Hammerhead Sharks - Research Paper Example The characteristic hammer shaped head of these ocean predators is called cephalofoil and is the reason why they are called hammerhead sharks. The nostrils and eyes are located at the tip of the extensions. All hammerhead sharks belong to the genus Sphyrna. There are nine identified species of Hammerhead shark and all have the characteristic projections on both sides of the head. The largest Hammerhead species, the Great Hammerhead shark, can grow up to 20 feet in length and weigh up to 1,000 pounds, although smaller sizes are more common (National Geography). The smallest of this species is the Bonnethead, which can reach an average length of 3-4 feet and can weigh up to 24 pounds (University of Florida). Cephalofoil: Structural Variations There are two main theories regarding the development of the cephalofoil. Some scientists believe that the shape evolved gradually over numerous generations, while others suggest that it was a sudden mutation that rapidly proved to be an advantage (Aquatic Community). The shape of the cephalofoil has been found to vary considerably among the various species of Hammerhead sharks. The great hammerhead has a cephalofoil that is broad and nearly flat across the front, with a single shallow notch in the center. The scalloped hammerhead is arched more and has a pronounced center notch with two matching notches on either side, giving it a scalloped appearance. The smooth hammerhead is smooth with no notches but a slight broad arch. The cephalofoil of a bonnethead is rounded at the front and resembles a shovel more than a hammer. Function of Cephalofoil Researchers are not sure about the function of cephalofoil in hammerhead sharks, but they have a few theories, some of which hold up well under research. The prominent theories which have been tested are listed below: 1. Enhanced binocular field In this study, scientist hypothesized that one of the main features of the cephalofoil is to enhance frontal binocularity (McComb et al. 4010 ). As part of this study, they compared the visual fields of three hammerhead species: the bonnethead shark (Sphyrna tiburo), the scalloped hammerhead shark (Sphyrna lewini) and the winghead shark (Eusphyra blochii) with the visual field of two carcharhinid species: the lemon shark (Negaprion brevirostris) and the blacknose shark (Carcharhinus acronotus). Scientists also quantified the eye rotation and head yaw of these sharks in order to determine if species compensate for large blind areas anterior to the head. The study revealed that the winghead shark possessed the largest anterior binocular overlap which was nearly four times larger than that of the lemon and blacknose sharks (McComb 4013). The binocular overlap in the scalloped hammerhead sharks was greater than the bonnethead sharks and carcharhinid species (McComb et al. 4013). However, the bonnethead shark did not differ from the carcharhinids (McComb et al. 4013). The hammerhead species did not demonstrate greater eye rota tion in the anterior or posterior direction. However, both the scalloped hammerhead and bonnethead sharks exhibited greater head yaw during swimming than the lemon and blacknose sharks, indicating a behavioral compensation for the anterior blind area (McComb et al. 4013). The results indicate that hammerhead species have larger binocular overlap compared to the carcharhinid sharks which is consistent with the ‘enhanced binocular field’ hypothesis. 2. Head Morphology Scientists have conducted a comparative morphology test to determine if the sphyrnid cephalofoil offers better stereo-olfaction, increases olfactory acuity and samples a greater volume of the medium compared to the carcharhiniform sharks (Kajiura et al., Morphology 253). The broadly spaced nares provides significantly greater separation between the

The Story Behind Bell Essay Example for Free

The Story Behind Bell Essay â€Å"Mr. Watson, come here. I want you. † These famous words by Alexander Graham Bell were spoken twice – first when the first sentence on the telephone was transmitted, and second when the first transcontinental sentence was exchanged (Feinstein 76, 92). This great genius may be world-famous for his invention of the telephone, but he preferred to be known as something else – the teacher of the deaf (World Book 2001 240). Not only was this brilliant man the creator of the device that transmits speech but also an educator and a very curious human being who desired knowledge and continued to test new ideas throughout his long and productive life. You can see how he changed and influenced the world through the years of his early life, his achievements, his miraculous telephone and its impact on the world, and his other creative inventions. Bell was born on March 3, 1847 in Edinburgh, Scotland (Foster). He was named after his grandfather, Alexander Bell and got his middle name, Graham from a family friend. His father, who was also named Alexander, taught deaf-mutes on how to speak, whereas his mother Elisa was a painter (World Book 2001 240). He was a talented musician, and could play by ear from the years of his childhood which resulted in him receiving a musical education (World Book 2001 240). Bell enrolled as a student teacher in West Howe – which was a boys’ school near Edinburgh – and taught music and speech in exchange for being tutored in other subjects (World Book 2001 240). He eventually started his own school for deaf teachers in 1872, which was one achievement of his in the line of many, although his most important one was the telephone. Ever since he was young, he had a fervent interest in human voice and an ambition for fame and fortune. From the time when Samuel Morse invented the telegraph, Bell was determined to create a new and improved version. In other words, he wanted to be able to transmit human speech. He worked with his partner, Thomas Watson, whom he met at an electrical instrument-making workshop, because he lacked necessary parts (World Book 2001 241). Together, they worked on the creation of the telephone – using a wire, a transmitter, and a receiver. On March 1876, Bell was adjusting the transmitter in the lab of his apartment. Watson was in another room adjusting the receiver, and the door between them was shut. Bell accidentally spilled battery acid on himself, and said those famous words – â€Å"Mr. Watson, come here. I want you,† which Watson heard in the other room through the receiver (Creating America 588). Life flew by for Alexander and Thomas after that. The first telephone patent was issued on March 7, 1876 (World Book 2001 241). The French government awarded Bell the Volta Prize of 50,000 francs, and he used that money to set up more labs, which also meant that he accumulated teams of bright engineers to pursue new ideas (World Book 2001 241, Bellis). Before they knew it, telephones were widely used in the United States. In 1880, more than 50,000 telephones had been sold. A year later, that number changed to 132,000 (Feinstein 89). In 1915, the first transcontinental phone call took place between Bell – who was in New York City, and Watson – who was on the other side of the country, in San Francisco (Feinstein 92). Because this took place, it opened up a whole new level of possibility for Americans. If we could get a telephone call across the country, then why not across the whole world? Today, telephones are widely used, and we all have Bell to thank although not only for this one task. Some more accomplishments of his were when he was elected the first president of the National Geographic Society, and also when he founded the Journal of Science (Ament). Although these achievements may be big, they were not as great as the invention of the telephone. As a result, Bell created the â€Å"Bell Telephone Company† in 1885, which also led to the creation of the â€Å"American Telephone Telegraph Company† (ATT), which still exists today. (Feinstein 89). The invention resulted in Alexander demonstrating his telephone at the Centennial Exhibition in Philadelphia in 1876, and also for Queen Victoria at the Royal Palace (Feinstein 79, 82). Several major scientists at the time saw his exposition, and declared â€Å"Here is the greatest marvel ever achieved in electrical science,† (Creating America 588). Two days after the exhibition, he married Mabel Hubbard and had two daughters – Elsie and Marian (Feinstein 84). They sailed to England and introduced the telephone to the British. The telephone changed the whole world to an unimaginable extent, and it all started with an accident in his lab. Although this creation was one of Bell’s more successful inventions, he also had many that were not as well-known, but were developed with such cleverness that it plainly shows his creativity and hobby for experimentation. Alexander always strived for more knowledge, which meant that he experimented whenever possible. In 1880, he invented the photophone, which transmitted sound over a beam of light (Feinstein 99). He also devised a kite capable of carrying a person, and a â€Å"hydrodome,† which was the fastest boat in the world for several years, travelling at an average speed of 70 mph (Ament). Another one of his well-known inventions was a metal detector, which came in useful when President James Garfield was shot. On July 2, 1881, doctors probed the President’s body with bare and unwashed hands, hoping to find the bullet. They were unsuccessful and called Bell, expecting him to use his metal detector. When Bell first invented this device, he tested it on Civil War veterans who still had bullets in them, and was successful for every single person. When it came to the president, however, it did not work. Garfield eventually died from blood poisoning from the doctors’ filthy hands. After his death, Bell found out that his metal detector was fine, but the springs in the President’s bed had interfered with the functioning of the machine. Many newspapers incorrectly blamed him for the president’s death, but those close to him knew that he had tried his best, and that the death was not his fault in any way (Feinstein 103, 106). Inventing the telephone alone would’ve earned Bell lifelong fame and respect, but he continued to create or improve devices to make the world a better place. Forty-one years later Bell himself passed away. On August 2, 1922, Pernicious Anemia, a blood disease, sadly claimed his life at the age of 75 (Bellis). He is remembered for being the inventor of the telephone, and making the world a smaller place, because friends and family were now just a phone call away. To honor his death, the millions of telephone lines served by the Bell Telephone System in USA and Canada went silent for a whole minute, letting the people remember who invented it and how it dramatically changed the world (Ament). To this very day we can see how Alexander Graham Bell changed each and every one of our lives, and made the world what it is through the years of his early life, his accomplishments, his extraordinary telephone and its impact on the world, and his other astounding creations. He followed his dreams and desires, and told us all to â€Å"Leave the beaten track occasionally and dive into the woods. Every time you do so you will be certain to find something that you have never seen before. † ~Alexander Graham Bell (Feinstein 5).

Jules Vernes A Journey to the Center of the Earth :: essays research papers

In the novel, A Journey to the Center of the Earth, author Jules Verne tells the fictitious story of three men and their adventures as they descend into the depths of the earth. The leading character in this expedition is a fifty-year-old German professor named Hardwigg. He is an uncle to the narrator, Henry (Harry), a simple Englishman. The other man is Hans, a serene Icelandic guide. Professor Hardwigg finds a piece of parchment that written in Runic in a book. Harry finds out before his uncle that it says there is a way to get into the center of the earth through a mountain (Mt. Sneffels) in Iceland. Harry is reluctant to tell his uncle the message because he is afraid his uncle will actually want to visit the center of the earth. He was right because the professor wanted to explore as soon as possible. They head off to Iceland, and, along the way, receive Hans as their guide. The journey to the mountain itself takes a while. They reach the entrance to the center, and from there, they head inside. Once in the dark labyrinths, they descend (this goes on for days). The three men then face difficulties: thirst, light, getting lost, injuries, and fatigue, were among them. They make many discoveries. They find that there’s a sea, with fish and sea monsters. They find forests, giant mushrooms, animals that look like dinosaurs, and even what seems to be giant human beings. The idea of writing this story came from a scientist who explored the crater of a certain mountain. Verne got the idea that maybe it would be possible to descend even further into the earth. Many of Verne’s â€Å"fantasy† stories have come true in the years following his death in the year 1905. A Journey to the Center of the Earth is farthest from reality. Even with the technology we have today, it would be impossible for one to descend into the earth. For one thing, we know now that the earth can’t be hollow because of extreme pressures and temperatures. People became interested in Verne’s stories during his time because though they were unrealistic, they were too interesting and entertaining to pass up. Some people even believed he had traveled to the many places that he wrote of. While checking into a hotel once, the woman told him to rest well in the room because he must be tired from his many adventures.

Stress and Anger Essay -- Stress Anger Psychology Essays

Stress and Anger Stress and Anger have always been related with each other. There have been countless studies, even more theories, about stress and anger and how they relate. But, no matter how many studies are conducted, there will always be the questions about whether or not stress and anger are related. But, I am here to provide the facts on both stress and anger, and then allow you, as the reader, to determine the relationship, because all-in-all, I feel that stress and anger can and cant be related, depending on the circumstance. If psychologists completely understood how stress and fears developed, we would know how to produce and reduce a phobia or an anxiety state. We don't. There seems to be a wide variety of life experiences which result in some form of stress, fear, anxiety, or psychosomatic illness. It would be convenient if life were simpler but it isn't. Perhaps a summary will help you review the ways you might become stressed and anxious Changes, such as sudden trauma, several big crises, or many small daily hassles, cause stress. Intense stress years earlier, especially in childhood, can predispose us to over-react to current stress. Events, such as barriers and conflicts that prevent the changes and goals we want, create stress. Having little control over our lives, e.g. being "on the assembly line" instead of the boss, contrary to popular belief, often increases stress and illness. Many environmental factors, including excessive or impossible demands, noise, boring or lonely work, stupid rules, unpleasant people, etc., cause stress. Conflicts in our interpersonal relationships cause stress directly and can eventually cause anxieties and emotional disorders. The human body has different ways of responding to stress; one quick responding nerve-hormonal system involving adrenaline, another long-lasting system involving cortisol, and perhaps others. These systems not only determine the intensity of our anxiety reactions but also our attitudes, energy level, depression, and physical health after the stressful events are over. As individuals, our nervous systems differ; however, according to Richard Dienstbier at the University of Nebraska, we may be able to modify our unique physiological reactions by learning coping skills. The genetic, constitutional, and intrauterine factors influence stress. Some of us may have been born "nerv... ...nd anti-social behavior. It is also known that a viral infection, called rabies, causes violent behavior. About 90% of women report being irritable before menstruation. Furthermore, 50% of all crimes by women in prison occurred during their menstrual period or premenstrual period. By chance only 29% of crimes would have occurred during those eight days. Hypoglycemia (low blood sugar) increases during the premenstrual period and it causes irritability. In all of these possibilities--instinct, heredity, hormones, or brain dysfunction--the aggression occurs without apparent provocation from the environment (although there is almost always a "target"). According to some of these theories, the need or urge to be aggressive is boiling within each of us and seeks opportunities to express itself. There is also clear evidence that alcohol consumption and hotter temperatures release aggression, but no one thinks there is something in alcohol or heat that generates meanness. The socialization process, i.e. becoming a mature person, involves taming these destructive, savage, self-serving urges that probably helped us humans survive one million years ago but threatens our survival today.

Native Americans in the United States and African American Cowboys Essay

APUSH, DAY-2-2 TO WHOM AND TO WHAT EXTENT WAS THE AMERICAN WEST A LAND OF OPPORTUNITY 1865 – 1890 During the year of 1865 to 1890, the American’s west land was a land of economic development for Native American, white settlers from the east across the Mississippi farmers, miners, ranchers and as well as African American cowboys and immigrants for Irish and Chines, moving west for goal of economic achievement and their position for profit. First, the Native Americans people opened the way of exploitation of the west land naturel environment. The Dawes Act, which turned Indians into landowners and farmers and distributed 160 acres for farming, designed Indians as individual rather than a group of tribes. The railroad made their trip easier, which Pacific Railroad Act was passed in 186, law allowed construction of new transportation systems. The Act also provided grants of land and limited jobs for immigrants’ worker on railroad, especially Chines immigrants worked for a lower wage and discovered millions of gold and silvers. The immigrants worked for a wealthy white settler in the west. Moreover, the railroad opened faster access for transportation for castles, miners and all the peoples, who were making money. Including the Homestead Act was passed; its offered 160 acres of land for any settlers live on the land for five or more years with little registration fees. It helped poor people to achieve economic business and farmers who needed more land, were permitted to purchase of up to 160 acres of land for $2. 50. The farmers took advantage of Westland by doing international market, which mostly depended on railroads for shipment. Even farmers had difficulties of weather conditions, the produced the agricultural business by the Bonanza farm. The farmers were hopes to getting rich soon. Together with the African American cowboys and cattle industry turned into a new marker as well. Because of Indians on to new reservation and the railroad opportunities bring them easier transportation anywhere in urban markets; without the railroads the new business were take a time to make money . In brief, west land was a place of a new beginning for people who were moving for seeking life and opportunities and hoping to get rich. The wealthy white settlers made the most profit in Westland.

The Ebola Virus Essays - Ebola, Animal Virology, Biological Weapons

The Ebola Virus Essays - Ebola, Animal Virology, Biological Weapons The Ebola Virus By: Wesley Mark Whitworth Ebola is an extremely deadly virus in our society today. Some even claim that is the most deadly ever discovered. Ebola is a member of the filoviruses (a family of RNA-BASED viruses). Filoviruses get their name from their peculiar shape. They appear to be long threads or filaments (henceforth the name filoviruses) *See attached photo. This virus was discovered in 1976 in Zaire, Africa and in Western Sudan, Africa. During the first outbreak there were approximately 550 cases leading to 340 deaths. Three years after the first outbreak, a smaller outbreak took place in Sudan, Africa. This outbreak was much smaller though, with only 34 cases and 22 deaths. The cause of this virus is still unknown. All that they really know is that the whole simian genus is susceptible to this disease (that includes most all members of the ape, chimpanzee, and various other monkey families). It can be carried though, through rodents (mice, rats, etc.), insects (mosquitoes, ticks, lice, etc.), and parasit es (small bacteria). This disease is classified as a viral hemorrhagic fever. That means that the disease has very distinct qualities. Ebola starts out as muscle aches, light fever, and your basic flu symptoms. Ebola then progresses to respiratory problems, server bleeding of most all of the bodies orifices, kidney problems, and then death. Basic symptoms include: fever, headaches, muscle aches, sore throat, loss of appetite, diarrhea, and your other common flu symptoms. Ebola symptoms usually begin within three to sixteen days after initial contact. Although most cases result in death, it sometimes may appear as just a light flu. It is very contagious. Ebola can be spread by the aforementioned animals, or by personal contact. It also can be spread through sexual contact (even after recovery for a short period). Doctors can detect this virus in much the same manner as they detect tuberculosis. They check for antigens already present in the body or they can take a throat culture and detect it. Contracting the disease in the United States is highly unlikely though. The only people who are even put at risk are those that visit Zaire or come in contact with people who do. The United States as well as the Zaire government both have strict quarantine policies involving the disease. Anyone who wishes to find out more about precautions and measures that must be taken if visiting Zaire, you may contact the U.S. State Department at 202-647-5225. They have all the travel information and requirements you need to get into and out of the country.

The Battle At Midway Essays - Battle Of Midway, Japan, Free Essays

The Battle At Midway Essays - Battle Of Midway, Japan, Free Essays The Battle at Midway Nothing distinguished the dawn of June 2, 1942, from countless other dawns that had fallen over tiny Midway atoll in the North Pacific. Nothing, that is, except the tension, the electric tension of men waiting for an enemy to make his move. On Midway's two main islands, Sand and Eastern, 3,632 United States Navy and Marine Corps personnel, along with a few Army Air Force aircrews, stood at battle stations in and near their fighters, bombers, and seaplanes, waiting for the Japanese attack they had been expecting for weeks. The carrier battle of Midway, one of the decisive naval battles in history, is well documented. But the role played by the Midway garrison, which manned the naval air station on the atoll during the battle, is not as well known. Midway lies 1,135 miles west-northwest of Pearl Harbor, Oahu. The entire atoll is barely six miles in diameter and consists of Sand and Eastern islands surrounded by a coral reef enclosing a shallow lagoon. Midway was discovered in 1859 and annexed by the United States in August 1867. Between 1903 and 1940, it served both as a cable station on the Honolulu - Guam ? Manila underwater telegraph line and as an airport for the Pan American Airways China Clipper (Miracle 5). In March 1940, after a report on U.S. Navy Pacific bases declared Midway second only to Pearl Harbor in importance, construction of a formal naval air station began. Midway Naval Air Station was placed in commission in August 1941. By that time, Midway's facilities included a large seaplane hangar and ramps, artificial harbor, fuel storage tanks and several buildings. Sand Island was populated by hundreds of civilian construction workers and a defense battalion of the Fleet Marine Force, while Eastern Island boasted a 5,300-foot airstrip. Commander Cyril T. Simard, a veteran naval pilot who had served as air officer on the carrier USS Langley and as executive officer at the San Diego Air Station, was designated the atoll's commanding officer. Along with the naval personnel manning the air station was a detachment of Marines. The first detachment was from the Marine 3rd Defense Battalion; it was relieved on September 11, 1941, by 34 officers and 750 men from the 6th Defense Battalion under the command of Lt. Col. Harold D. Shannon, a veteran of World War I and duty in Panama and Hawaii. Shannon and Simard meshed into an effective team righ! t away. World War II began for Midway at 6:30 a.m. December 7, 1941, when the garrison received word of the Japanese attack on Pearl Harbor. At 6:42 p.m., a Marine sentry sighted a flashing light out at sea and alerted the garrison. Three hours later, the Japanese destroyers Sazanami and Ushio opened fire, damaging a seaplane hangar, knocking out the Pan American direction finder and destroying a consolidated PBY Catalina flying boat. The Japanese retired at 10:00 p.m., leaving four Midway defenders dead and 10 wounded. On December 23, 1941, Midway's air defenses were reinforced with 17 SB2U-3 Vought Vindicator dive bombers, 14 Brewster F2A-3 Buffalo fighters, and pilots and aircrews originally intended for the relief of Wake Island. The Buffaloes and Vindicators were cast-off aircraft, having been replaced by the Douglas SBD-2 Dauntless dive bombers and Grumman F4F-3 Wildcat fighters on U.S. aircraft carriers. The Buffaloes became part of MarineFighter Squadron 221 (VMF-221), while! the Vindicators were put into Marine Scout Bombing Squadron 241 (VMSB-241), both making up Marine Air Group 22 (MAG-22) under Lt. Col. Ira B. Kimes. Midway settled into a routine of training and anti-submarine flights, with little else to do except play endless games of cards and cribbage, and watch Midway's famous albatrosses, nicknamed gooney birds, in action (Stevens 56). Then, in May 1942, Admiral Isoruku Yamamoto, commander in chief of the Japanese Combined Fleet, came up with a plan, called Operation Mi, to draw out the U.S. Pacific Fleet by attacking Midway. Using Midway as bait and gathering a vast naval armada of eight aircraft carriers, 11 battleships, 23 cruisers, 65 destroyers and several hundred fighters, bombers and torpedo planes, Yamamoto planned to crush the Pacific Fleet once and for all. Alerted by his code-breakers that the Japanese planned to

Network Architecture in Entrepreneurship

Network Architecture in Entrepreneurship Free Online Research Papers The significance of networks as integral part of the explanation of entrepreneurial accomplishment is widely accredited. Ethernet, wireless LAN, WAN, MAN, ADSL, cable modem and dialup are common access networks, but have significantly diverse characteristics. Fast and accurate taxonomy of access network type can perk up protocol or application performance drastically. In this paper I make a distinction between large and small business enterprises on basis of network structural design. This distinction is introduced as a contingency in the way networks contribute to the capability of the industries to ascertain opportunities, to acquire resources, and to achieve authenticity. 1. INTRODUCTION The network of an enterprise plays a significant role in the search for latest opportunities and the quest for resources. In this paper I’m interested in comparing network architecture of two organization and their usage features. I will research extensively in order to find the best possible network for: ? A small business or a medium sized office ? A large business 2. NETWORK DEFINITION: Information system executed with a group of interconnected nodes. Computers on a network are called nodes. There are several diverse ways to network computers together. There are numerous types of computer networks, including: ? Local-area networks (LANs): The computers are physically close together (in the same building). ? Wide-area networks (WANs): The computers are farther apart and are linked by telephone lines or radio waves. 3. NETWORK RELATIONSHIP TYPES The term network relationship refers to two different concepts concerning how one computer utilizes computer resources of another computer over a network. Two fundamental types of network relationships exist: ? Peer-to-peer ? Client/server These two types of network association describe the very configuration of a network. For instance, a peer-to-peer network is to a great extent similar to a company run by decentralised management philosophy, where decisions are made locally and resources are managed according to the primarily urgent requirements. A client/server network is further like a company that works on centralised management, where decisions are made in a central site by a rather small group of individuals. Circumstances exist where both peer-to-peer and client/server relationships are suitable and several networks have features of both kinds contained in them. Both types of networks necessitate a physical network link between the computers and the same network protocols are to be used. There is no differentiation amid the two types of network association at this point. The disparity transpires when you extend the shared network resources around to entire computers on the network or employ a centralised network server(s). 4. NETWORK STRUCTURE IN SMALL ORGANIZATION LAN: Local Area Network (LAN) is a computer network that spans a reasonably small area. Most LANs are restricted to a sole building or group of buildings. Most LANs connect workstations and personal computers. Each node (individual computer ) in a LAN has its own CPU with which it executes programs, but it also is capable to access data and devices everywhere on the LAN. This means that several users can share high-priced devices, such as laser printers and at the same time data as well. Users can also utilize the LAN to communicate with each other. This distinctive characteristic on a wired LAN offers unbounded bandwidth on the network by allocating a separate broadband connection to be connected to each Complex Broadband Router on the network. 5. NETWORK DESIGN IN LARGE ORGANIZATION: WAN: Wide Area Network (WAN) is a computer network that envelops a broad area (i.e., every network whose communications links cross metropolitan, regional, or national borders). Or, a network that uses routers and public communications links. Compared with personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are typically restricted to a room, building, campus or specific metropolitan area (e.g., a city) correspondingly. The major and most recognized illustration of a WAN is the Internet. WANs are built to offer communication key for organisations or people who require exchanging digital information involving two places. The chief function of a WAN is to provide consistent, swift and secure communication among two or more places through small delays and at low costs. WANs facilitate an organisation to have one fundamental network amid all its departments and offices, even if they are not all in the identical environment. WANs are used to connect LANs and other types of networks simultaneously, so that users and computers at one place can communicate with users and computers at other locations. Many WANs are designed for one specific organization and are personal. Others, built by Internet service providers, supply connections from an organizations LAN to the Internet. WANs are often built via leased lines. At every end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Leased lines can be incredibly costly. As a substitute of using leased lines, WANs can also be built using less expensive circuit switching or packet switching techniques. Network protocols including TCP/IP send transport and addressing tasks. Protocols together with Packet over SONET/SDH, MPLS, ATM and Frame relay are frequently used by service providers to distribute the links that are used in WANs. X.25 was an significant early on WAN protocol, and is well thought-out to be the grandf ather of Frame Relay as countless of the basic protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.

Judaism Assignment Example | Topics and Well Written Essays - 250 words

Judaism - Assignment Example The Holocaust can be construed as generating the same kind of spiritual and psychological upheaval that it did during the time of the 597 BC exile, generating the same intense scrutiny of the Jewish faith and Jewish purity in relation to that covenant (Hooker, 2013). ‘What you believe follows only after what you do’ is a moral prescription, and a guide for judging what is right and wrong. This is another way of saying that actions are the true things, and that it is our actions that determine whether we are moral or not. It is another way of saying that we ought to do what is right, and that belief is only secondary to how we act. This places emphasis on right action as a key feature of Judaism. There is the sense that while Judaic beliefs and customs may seem complicated, in fact the crucible of moral judgment focuses on actions and in a way the effects of those actions on people. Jewish customs being the subject of rediscovery means those same customs being found to have relevance in the lives of modern-day Jews (Tippett,

Film Report Movie Review Example | Topics and Well Written Essays - 1000 words - 3

Film Report - Movie Review Example The film’s theme follows a courtroom drama that involves a battle of argumentative wits between and among brilliant lawyers. The audience can see the theme initially when Manion’s wife, Laura, talked to Stewart over the phone and asked him to defend her husband. It then follows that Stewart met with Laura and Frederick in the jail, and Stewart decided to accept the case. The film used an element of legal objects and subjects, such as Stewart’s law books and the introduction of Manion’s murder case. 2) What were the choices made by the main characters and what were the consequences of those choices? First of all, when Stewart accepted to represent the defendant on court, he embarked on a tedious journey of courtroom arguments in order to defend well an accused murderer. Manion’s wife also proved to be a disadvantage on the part of the defense because of her flirty and happy-go-lucky aura. Moreover, Stewart faced some dubious statements both from Fred erick and Laura which make it harder to patch things together consistently. Stewart’s appearance on the courtroom also showcased his unique temperament which shifts from being reserved to a sudden emotional outburst and rage. Furthermore, the judge also made important decisions while the case is going on. There in that trial, tabooed words in the court were used, such as ‘panties,’ ‘slut,’ and ‘bitch’ (Brunson par. 1). Now, these words have been legally used in trial cases. Lastly, the judge’s decision in giving the victory to Stewart’s camp was prompted by Mary Pilant’s decision to give in to Stewart’s request to side with their camp and tell the court that she herself found the undergarment in their laundry room. Pilant’s decision to reveal her identity as Quill’s daughter in the court made a stunning and shocking effect on the prosecution. As a result of their collaboration, Manion was freed a nd was charged not guilty of murder. 3) What three or four sequences are most important in the film? Why? These important sequences in this movie happened during the courtroom procedure. However, the first scene that can be considered important was when Stewart visited Manion for the first time in jail which initially got Stewart his impression towards Manion. He also learned about his marriage with Laura. It then follows that Stewart was set for the murder trial because he found out a precedent for ‘irresistible impulse’ in a Michigan court decision, and he began a battle with the two prosecution lawyers. Stewart, in one of his arguments, insisted that Quill and Manion had troubles before the murder happened because the former might have a fondness for Laura, and that Manion murdered Quill out of irresistible impulse, meaning he did not deliberately kill Quill but did so because he was ‘forced to its execution by an impulse.’ The case was sealed after Mary Pilant agreed to lie in court and tell the jury that she found Laura’s underwear in their laundry room suggesting that Quill did rape Laura. 4) Did the ?lm surprise you with anything unusual in its story, style, technique, or implications? Although I have seen modern courtroom drama films, such as My Sister’s Keeper, Erin Brockovich and The Exorcism of Emily Rose, I can say that this movie surprises me

Performance management is key to achieving sustained competitive Essay

Performance management is key to achieving sustained competitive advantage - Essay Example advantage (Amit & Schoemaker, 1993; Barney, 1991; Schoenecker & Cooper, 1998). Human capital is more mobile than other intangible resources (Teece, Pisano, & Shuen, 1997). Therefore, it may seem an unlikely source of sustained competitive advantage. Hence the organization must search for the means and ways to retain them to achieve completive advantage. Competitive advantage is gained only when the organization selects or develops these resources and structures work tasks and the reward system in ways that motivate the team to perform well and thereby contribute to organizational effectiveness (Guzzo & Shea, 1992). Some organizations reward employees financially when they demonstrate an ability to acquire and master new knowledge (Jenkins & Gupta, 1985; Gerhart, 2000; Lawler, ch-10).Also some studies like, Jackson & Schuler, 2002 considers that organizational structures for rewards improve organizational performance and proves competitive advantage rather than team effectiveness and selection and training. But according to Dobbins, Cardy, Facteau, & Miller, 1993 opinion, system factors are the only constraining influences that restrict individual ability and motivation, and result in lowered performance. Performance management involves enabling people to perform their work to the best of their ability, meeting and perhaps exceeding targets and standards, and hence the PM system involves the following components.1. The focus is on an individual's work.2. There are expectations or standards of performance.3. There are usually two sessions between the employee and the evaluator: one to establish the standards and another to review performance. 4. The evaluator is usually the person who has line management authority over the one evaluated. 5. The evaluation session usually results in some written conclusion--some paper trail regarding the performance of the person reviewed. Corporate Performance Management (CPM) has become a widely adopted strategy execution in the current day corporate scenario with systematic and integrated improvements in the management processes to ensure efficiency and effectiveness. At the core of CPM is A metrics-based strategic planning and execution framework that helps align strategic plans with resource allocation and strategic initiatives Strategic goal alignment through enhanced communication and focusing processes / resources towards organization objectives A structured information based review mechanism that provides the feedback loop and connects strategic planning to operational performance measures Eg: Infosys is a best example to observe the competitive advantage of the company that has achieved through the adoption of CPM approach. Performance management and improvement is observed as Cycle to adopt in the process with certain steps. The practice of Infosys CPM is observed through the following steps of PM cycle. 1. Performance planning: Here

Genetics of Type 1 Diabetes Research Proposal Example | Topics and Well Written Essays - 750 words

Genetics of Type 1 Diabetes - Research Proposal Example Although this is significantly reduced as compared to Europe, this still represents a statistic that is most certainly higher than should be represented (Klompas et al., 2013). A large portion of research with respect to type I diabetes has been concentric upon heredity and environment. Ultimately, the research that is been concentric upon environment necessarily weighs pollution, exposure to sunlight, diet, and other relevant factors (Hilmi et al., 2013). By contrast, the analysis that is been concentric upon heredity has focused mainly upon genetic indicators. As such, many of the genetic indicators that have been linked to potentially encouraging or otherwise exacerbating a risk rate for type I diabetes include haplotypes of the human leucocyte antigen; these include: HLA-A, HLA-B, HLADRB1 as well as HLA-DQB1 genes. Researchers have noted that the association to Type 1 diabetes that these genes portend is concentric upon auto-immune issues that an individual is exposed to if they have these specific genes. Beyond these, IDDM1 through IDDM18 have also been noted to have a clear and distinct linkage to the possibility of an individual developing Type 1 di abetes at some point in their lives. Further, beyond genes that deal with the regulation of proteins or amino acids, CTLA4 has been clearly linked to an increase in the potential of an individual to develop Type 1 diabetes as well. This is due to the fact that the CTLA4 gene plays a regulatory role in the body’s immune system; therefore the prevalence of this gene or absence thereof has a contributing effect with respect to Type 1 diabetes (Lundgren et al., 2013). As Type 1 diabetes is understood in terms of a disease that is exacerbated and/or evidenced by the prevalence of key genes, understanding a differential between these genes and how they relate to individuals of different racial backgrounds is key to better understanding Type 1

The Cognitive Approaches of Challenged the Concept of Behavioral Essay

The Cognitive Approaches of Challenged the Concept of Behavioral Theory - Essay Example A child learns new behaviours or is able to modify existing behaviours, as a function of environmental events that either reward or punish that behaviour. Skinner’s learning theory is a move away from the traditional behaviourist approach of stimulus and response, as he differentiated between types of responses. When a response was elicited by a known stimulus it is considered to be associated with the known stimulus. Alternatively, responses that do not require a specific stimulus, which he termed operants, are independent of the stimulus. Skinner emphasized that it was the operant response that could be strengthened or weakened by the use of personal, social or environmental rewards or punishments respectively. Skinner’s principles advocated the idea that learning could be ‘programmed,’ which fit with the 1960s initial explorations into computer-aided instruction. All that was required was for the student to practice, and to be provided with the ideal rei nforcement (i.e., reward or punishment). Students were perceived to learn through processes of rote memorization and amount of practice. A subject such as English has been greatly influenced by Skinner’s principles of reinforcement in terms of being better able to regulate student behaviours and learning achievements. Information is reduced by the teacher into smaller components (e.g., poetry, spelling, vocabulary), and organized by the teacher into a format believed that the student will understand and can systematically build on.

Literary research Essay Example | Topics and Well Written Essays - 1250 words

Literary research - Essay Example Women searches for ways and means to be appreciated in response to obvious inequality to the relevant worth of existence. The current research aims to expound, through the novel as the backdrop, the apparent unequal role of women compared to men during the historical frame, particularly in the 1930s. II. Status of Women’s Roles in Society in the 1930s A. Brief description of women’s roles The discourse written by Moran clearly illustrated the roles of women in society during the 1930s. This time period was depicted as the Great Depression, where â€Å"worldwide economic collapse following the stock market crash in 1929, in which unemployment remained high for an extended period and many businesses failed† (Investor Words, par. 1). Therefore, despite the spur of enlightenment of women towards the promotion of equal rights through the passage of laws depicted in the 19th Amendment in 1920s, the economic slowdown and financial crisis delayed the persistent and deter mined focus to fight for equal rights. As Moran averred, â€Å"the 1930s brought apple-sellers to city street corners and breadlines to urban charity houses. In a depressed economy, unemployment figures escalated and federal forces concentrated on bringing Americans back to work. Or, more accurately, bringing American men back to work. For society viewed working women as un-American money grubbers, stealing jobs from men who needed them to support their families† (par. 3). B. Perceived Inequality of Women’s Rights Prior to efforts to fight for equal rights, women were rarely given the opportunities to be properly educated, to vote, to work or be employed, among others. The fact was validated in the article entitled How Does the Representation of Women Change Between 1930-1960 On the Covers of Vogue? The article revealed that â€Å"the 1930s were a less vibrant decade for women, seeing the depression, which meant that all women were encouraged to return to their homes whilst men returned to jobs that were becoming scarce. All their roles and responsibilities were taken away from them; the economy could not deal with the growing number of men returning to work. Any women who married therefore gave up her right to work. This meant women had to spend more time at home doing the domestic jobs that would normally be considered the women’s ‘job’† (How Does, par. 5). The setting was typically exemplified by Curley’s wife, who is left spending most of her time hanging around with the workers; rather than having something productive and rewarding done according to her skills and abilities. C. Effects of Inequality of Women The study conducted by Amartya Sen on the Many Faces of Gender Inequality has attested to the continued existence of inequality felt by women the world over. The author categorized inequalities in gender according to seven types, to wit: (1) mortality inequality (â€Å"high mortality rates of women and a consequent preponderance of men in the total population† (Sen, par. 3); (2) natality inequality (the preference accorded to male children over female); (3) basic facility inequality (opportunities for education, cultivation of one’s talents, and participation in social functions); (4) special opportunity inequality (pursuing higher education and delving into more professional training);

Omar Khayyam Was A Persian Mathematician History Essay

Omar Khayyam Was A Persian Mathematician History Essay Omar Khayyam was a Persian mathematician, philosopher, astronomer, physician and a poet. He was born in Nishapur, Persia on 18 May, 1048 (AD) and he died on 4 Dec, 1131 (AD). He wrote treatises on mechanics, geography, and music. Khayyam had superior intelligence, his expertise were in many different subject areas. Just like most ancient scientists Omar Khayyam was also a polymath. Khayyams full name was Ghiyath al-Din Abul-Fath Umar ibn Ibrahim Al-Nisaburi al-Khayyami. A litteral translation of al-Khayyami is tent maker which possibly came from his father Ibrahims trade. Khayyam was an established astronomer and mathematician of the medieval period. He was recognized for the most important treatise on algebra, as shown in his Treatise on Demonstration of Problems of Algebra giving geometric method for solving cubic equations by intersecting a hyperbola with a circle. One of his greatest achievements in astronomy was that he came up with a calendar to figure the length of the tropical year. This calendar was so accurate that it is still used today. Khayyam was truly an intellectual being, whose legacy continues in the 21st century. Khayyam may have proposed a heliocentric theory a long time before Nicolaus Copernicus. This theory states that the sun is stationary and is placed in the center of the universe, and the earth and other planets revolve around it. Khayyam has not only impacted the Persian world but has also had a substantial impact in the west through literature and his scholarly work. Edward FitzGerald was one the man that made Khayyam famous in the western world. FitzGerald translated Khayyams work into English and the result was a small number of quatrains, also known as rubaiyaas in the Rubà ¡iyà ¡t of Omar Khayyà ¡m. Khayyam is well known for his scientific and poetic writings, but he has received very little credit as a philosopher and a teacher. Al-Zamakhshari was a famous medieval muslim scholar of Iranian origin. He recognized Khayyam as a philosopher of the world. Now there are many sources that confirm that Khayyam spent a lot of his life teaching the philosophy of Ibn Sina in Nishapur. Most of Khayyams life was spent in Nishapur, and he passed away there as well. He is buried in a masterpiece of Iranian architecture, which is visited by many people every year. Nishapur was located near an ancient civilization of china and India. Every year, the high school that Omar Khayyam attended has a national day of celebration, where they credit this genius mans work and pray that may god bring many more Omar Khayyam in the future. The original Nishapur city does not exist anymore due to some earth quakes and the Mongol invasions later on. Only some remains of Nishapur exist today. This was a very large city, in 1040AD Persia was invaded by the Turkish tribe know as the Sultans. They defeated the rulers and made this city the capital of their new empire. The sultans came converted to Islam and had knowledge of agriculture and civilization and they had no intention to destroy the land. During the time of Khayyam, the ruling king was Malik Shah, also known as JalÄ l al-Dawlah Malik-shÄ h. He was remembered as one of the greatest Seljuk Sultans and he ruled from 1072 to 1092. Under Malik Shahs ruling colleges in Nishapur were opened where some of the finest scholars studied, and Khayyam was one of them. People would come to Nishapur from all over the world to study and they would take Nishapurs great name back to their home with glory. Khayyam became so famous due to his work that a lunar crater and a small planet is even named after him. Abour 900 years after Khayyams death, his name appears everywhere in what is known in the modern days as Tehran. Manny people were inspired by Omar Khayyam genious work and a person with a name of Ali Dhebashi even wrote a book called May va Mina translated in English as Wine and the Wine Glass. The author mentions that he only wrote the book to satisfy his own curiosity. This book contains a collection of the most important articles about Khayyam on different aspects of life. This books presents a very accurate picture of Omar Khayyam, about his poetry, mathematics and his understanding of how he managed to understand the depth of the human spirit. Every summer professors and intellectual people gather in the University of Cambridge to celebrate Omar Khayyams achievements. The man responsible for making Omar Khayyam well known in the west was Edward FitzGerald. He was from a very wealthy Irish family, and his parents were known to be one of the richest people in England. FitzGerald went to Cambridge University, but never really had a profession or a job. He had a very nice personality and was very friendly person. FitzGerald soon became friends with a young linguist called Edward Cowell. In 1857, Cowell found some Persian poetry written by Omar Khayyam in a library located in Kolkata, India and gave them to FitzGerald. He translated this book and the first edition was published during January in 1859, it was titled as Rubaiyat of Omar Khayyam. This book did not gather much attention at first and it was not until 1868 that the Rubaiyat started to become famous and FitzGerald was urged to write a revised second version. The original Rubaiyat was produced around 550 years ago, and still it has been kept in its original condition. It is still hard for a person that speaks Persian now in the 21st century to translate just a couple of lines of the Rubaiyat into English. For that reason it is still recognized that FitzGerald had great talent and was also a very intelligent being. Mainly, people have seen Omar Khayyams as such a great figure because of the aspect in his poetry. Khayyam demonstrates his understanding of human nature, mans loneliness and the complex inner being of a human through poetry. Around 1070AD Omar Khayyam moved to a place called Samarqand which is now known as one of the oldest cities located in Uzbekistan. It was only here that Khayyam did his mathematical work, which would make him even more famous for that as well. Abu Tahir, a well known jurist supported Khayyam in Samarqand which allowed Khayyam to write some his most famous algebra work. Now days, most people think that mathematics was all created by the Greeks. Then, once the ancient Greek empire collapsed, the math discoveries were stopped until the Europeans started to prove new findings around late 1300s. In fact, there were a huge amount of discoveries being made in the eastern side of the world. Countries such as, China, India, Persia, and the Muslim world were discovering specifically a language that would come to be known as algebra during Omar Khayyams time period. During this time in the west, mathematicians were not aware of the achievements being made by young scholars in the east. Omar Khayyams greatest achievement in math was the cubic equation. Although he did not solve this problem of inventing a cubic equation, he got a partial answer to it. Omar Khayyam was very frustrated with this for some time, and he wrote that later one in the future someone would come uncover this secret and it was actually the Europeans that took Khayyams partial answer and c onverted it into a full equation. Music is a part of our daily life; it is the spirit of our languages. Mohammad Reza Shajarian is well known around the world now to be a master of Persian music. Over 30 years ago, he made an album containing Omar Khayyams Rubaiyat and it is still one of the best sellers today. One of the famous lines is Ah, make the most of what we yet may spend, before we too in the dust descend, Dust into Dust and under Dust to lie, Sans Wine, Sans Song, Sans Singer, and Sans End! (Edward FitzGerald, The Rubaiyat of Omar Khayyam) Many people still believe that Omar Khayyams poetry had a substantial influence on him as an astronomer and only this ability allowed him to achieve the great discoveries he made. Khayyam found the lunar calendar, one of his biggest accomplishments throughout his life. Even though Khayyam is mainly known in our world today as a great poet mainly, but he was well known in his time for revolutionizing the way time was calculated. Prior to the discovery of the lunar calenda r, people would celebrate spring when it was actually winter or vice versa. Over the years, the king figured the time was being calculated incorrectly. This was due to the time measurements being taken from the moon. The old time calculating method still had 12 months but it had only 354 days in a year, which were slowly decreasing. The king Malik Shah at the time of Omar Khayyam needed an accurate calendar since he collected tax from the public every year. So the rule was that when you harvest your crop, you have to pay the tax. Sometimes, the kings people would claim to want more tax due to the year being shorter, or other times the farmers would say we dont owe any tax this year. The founder of the Seljuk dynasty, Toghril Beg had made Malik Shah, his grandson the ruler of Esfahan. So in the early 1070s the king Malik Shah and his chief Nizam al-Mulk requested Khayyam to go to Esfahan and setup a place built for the intellectual astronomers, known as an observatory. Omar Khayyam led the scientists and studied the movements in space over 18 years and they m ade their greatest discoveries here. This period of time was of political peace, which helped to dedicate Khayyam to this scholarly work. These astronomers were ingenious, they learned from the Greeks achievements in the past that one had to observer accurately, be extremely careful and they required high technological instruments. Khayyam observed that the planets and the sun change position all the time. However, the stars stay fixed but only relative to each other, so the astronomers used certain stars as reference points. Later, these were known as the signs of the zodiac. The astronomers calculated the time it took to go from one star to the other, and these are now called the months. This allowed Khayyam to calculate the time it took for the sun to make a complete revolution around the earth, which is known as a year. Khayyam came up with the length of the solar year which is very accurate even until today. He measured the length of the year to be precisely, 365.24219858156 days. Scientists have now proven that Khayyams calculation was correct upto sixth decimal places, since the earths revolution only goes to six decimal places accuracy, Khayyam actually had predicted with the over amount of significant figures and this is how accurate his calculations were. Khayyam would use an instrument called Astrola be. It was an amazing technology, which would allow one to accurately check what time it is at a certain point in the day. Even until after about 900 years, there exist some clubs named after Omar Khayyam and Edward FitzGerald who took the ingenious author out of the shadow. A dinner club dedicated to both these authors still exists today in London. This club was built in the early 1890s and does not allow women to be a part of it, even now. Its members eat dinner together in the remembrance of both the great authors. There exists a Club of Omar Khayyam in the United States as well and in the University of Texas, they have the world largest collection of the Rubaiyat. Ever since FitzGerald started to publish Omar Khayyams work in the west, advertisements started using Omar Khayyams name in the books. There were games made after Omar Khayyams name and many dinner menus. In Khayyams poetry, his main message across the audience was life is short; enjoy it while you still can. He used to say that one should maximize life, and have another glass of wine while still they can. The argument still continues about how much FitzGerald translated the Rubaiyat and how much of it was his own work. The original Persian copy of the Rubaiyat was not written in much order but FitzGerald arranged the Rubaiyat in a chronological manner increasing the poetries depth and meaning. It was not too long until the peaceful political period ended during Khayyams time. In 1092, Malik Shah died and his chief Nizam al-Mulk was murdered in Esfahan due to a terrorist movement known as the Assassins. Then later, Malik Shahs wife ruled for two years and many people did not support her. Consequently, the obersvatory was shut down and the funding was stopped. This meant that Khayyams mission to reform the calendar was put on hold. After a little while, Khayyam had been attacked by a g roup of religious people that claimed Khayyam was questioning the faith of the believers. Soon, Khayyam came to know that no one was in his favour, but he still tried to remain calm and hoped to regain favour. As the time passed one, he wrote a book a book which described Irans previous rulers as being great men of honour, since they had supported the scholarly works of science. At this point in time of Omar Khayyam, the rulers of this empire were not in favour of promoting any sort of scholarly work. Sanjar, Malik Shahs third son became the leader of the Seljuk Empire in 1118AD. Under Sanjars ruling Merv became the capital of the empire. It is now located in Mary, Turkmenistan, here Sanjar built a great center of Islamic studies and Khayyam found many more of his mathematic findings here. Khayyam discovered here that the a cubic equation can have more than one solution. Sadly, he was not able to prove that there could even be three solutions but he wrote in his work that he hopes one day arithmetic solution might be found one day.

Analysis of Anne Bradstreets To My Dear and Loving Husband Essay

Analysis of Anne Bradstreet's To My Dear and Loving Husband Anne Bradstreet's poem, To My Dear and Loving Husband, shows her profound love and undying affection for her husband. For a Puritan woman who is supposed to be reserved, Bradstreet makes it her obligation to enlighten her husband of her devotion. She conveys this message through her figurative language and declarative tone by using imagery, repetition, and paradoxes. Over and over again she expresses her adoration for him with imagery. "I prize thy love more than whole mines of gold, Or all the riches that the east doth hold. My love is such that rivers can not quench,..." (5-7). Bradstreet is declaring there is nothing as powerful as the love she shares with her husband which is untouchable and eternal. These three line...

Lets Fire All the Managers

Already title is caching our attention : â€Å"First, Let's Fire All the Managers†. Intriguing start changes in the list of charges against the modern management system. The author is showing his critic for complicated system, where we have hundreds of managers in various level. He lists three main problems. As first is the costs of management which is very expensive. At second he shows that typical management hierarchy increases the risk of â€Å"calamitous† decisions with bad judgment. And as third multitiered management structure systematically disempowers lower-level employees. For all this three he is giving examples to make sure that readers will understand the problem. After that there is a lot of information about how this system is working and how the place of work is organized. So now we have question. Wouldn’t it be great if we could achieve high levels of coordination without a supervisory superstructure? To confirm theory author is giving very strong arguments by describing new management model called self-management which is in use at American company Morning Star. There are no employees, there are only â€Å"colleagues† which are taking personal responsibility for what they have done. And each person is at the same level. So if there is any problem other colleagues going to help to resolve it. There are no managers all the decision are made in the group of employees : â€Å"Around here, nobody’s your boss and everybody’s your boss. † To be sure that each employee now what he is doing and what kind of opportunities standing in front of him there are management courses , seminars which provide necessary information. As author is showing company have got only great achievement and there is only few small disadvantages. He is giving very strong arguments about almost â€Å"utopia† organization where everybody are happy. Everything sounds perfect but is it real? Using the Google’s I found Morning Star company. â€Å"One of the best, world’s leading tomato ingredient processor†. And as author shows, they have got self-management system in use. As a founders of the new system they create website â€Å"Self-management Institute† which provide all necessary information about new system . Self-Management is an organizational model where functions of a manager (planning, coordinating, controlling, staffing and directing) are pushed out to all participants in the organization as opposed to a select few. From that website we can read the main issue of new system, which is: self-directed work teams, employee empowerment, distributed decision making, â€Å"flattening† the organization, elimination of bureaucratic red tape . All of that is already successfully working in Morning Star company. To be sure author of article Gary Hamel , decide to check on his own that system. What he saw was very fast developing company where without even one manager, people working very efficiently. And the most important is that they know what they doing and feel responsible for that. They are more loyal and are better judgment because they are not lack of context and understand the facts from the ground. System, called pancake-flat, is not complicated, because there are no bosses. But who is making the big decisions? Giving power to everybody is scary, danger, for sure there must be someone responsible more than others. Summary. How can a big company survive without structure? For company like Morning Star where from the beginning the main system was self-management and all the structure was already prepared system was easy to absorb. In my opinion it would be difficult to put that system in mega companies with 100,000 employees. It would look like a loud school class with pupils, when teacher left for a moment and everybody doing what they want even when they were said to read book . That is why in big companies there always must be someone who is going to manage a group. It is almost impossible that 100,000 employees will work efficiently without manager. Self-Management gives a great deal of freedom to colleagues; isn't that dangerous? Freedom must be balanced with responsibility in any organization. Ofcourse employees need to feel free when they working no one like big pressure and stress on top of work. But if we going to say â€Å"Feel free†, probably their going to put their own targets first. If we gonna left them on their own, we will never be sure if they doing what they where asked for and don’t waste our time and money. The company creates an environment where people can manage themselves by making the main mission the boss and truly empowering people. Where everybody are on the same level, and every one are bosses. It is sounds like â€Å"One for all and all for one†. For sure one thing is good in system like that. It is much cheaper without managers which have to be paid bigger salary. Reading this article I started to thing that that was the main problem. And thet is why new system was invented. To save the money. In my point of viewself-management system is very intresting and very innovative. By the example of Morning Star company I can assume that it can work. Author is sure that is possible to improve this system in much bigger companies. And with that I can not agree. It can not work everywhere and with every person. It always depends on the place (where company is), kind of company, (it worked in a simple agricultural organization doesn’t mean it is gonna work at New York) and employees characters (there is always leading person and someone who only want to do his job) .

Demographics Report Essay Example | Topics and Well Written Essays - 1500 words

Demographics Report - Essay Example This has seen an increase in employment opportunities for previously under-utilized labor-force sources like women and generation U. Finally, demographic changes in Europe have created an increasingly global and mobile market. CHANGING DEMOGRAPHICS: ISSUES AND CHALLENGES FOR BUSINESS Introduction European states face challenges with the composition of their age structure changing substantially now and in the near future. Demographic change also requires development of urgent social policies. The concept of demographic change can be defined as the age structure of a population adjusting to various changes in the living conditions. These changes in the societal age structure composition result from social shifts. The European Union population pyramids show that, after the Second World War, the first two decades experienced especially high rates of birth. However, since the 1970s, professional demographers have begun to observe negative trends in Europe’s population structure. Lo wer rates of birth come, in the present and recent past, with ever-increasing life expectancy among Europeans. Ongoing low rates of birth have seen a progression towards an ageing society, as rates of mortality remain low. Consequently, approximately half of population growth forecasted in Europe between 2005 and 2050 will be because its population is living longer, rather than an increase in birth rates. Furthermore, the baby boomer generation is now coming past its retirement threshold and highlights a turning point in the development of demographics. This paper aims to discuss the impact of demographic changes on business operations in the United Kingdom and the larger European Union. The challenges of demographic change refer to the adjustments or changes arising from a society that is aging. Ageing of the population is a long-term trend that started decades ago in the European Union and the UK. This ageing has been most visible in the age structure development, reflected in the increasing share of older citizens, coupled with a declining share of persons in the working age in the total population. In the preceding two decades, the working age share in the European Union increased by 0.3% while that of the older generation grew by a more significant 3.7%. Because of this, top of the age pyramid for the EU-27 for the year 2012 has become larger as compared to that in the year 1992. This growth in older people’s relative share can be explained by an increase in longevity, which has been in evidence for some decades as life expectancy has also increased. This development is referred to as the population pyramid’s ‘ageing of the top’. On the other hand, low fertility levels have remained across the European Union, resulting in a decreased share of the younger generation. This is referred to as ageing at the bottom. The EU-27s median age development of the population also illustrates an ageing population. The median age has gone up fr om thirty five and a half in 1990 to forty one in the year 2012. The median age has risen in all the EU member states by at least seven years. Impacts of Demographic Changes in the EU and UK Never before has there been such a swift change in demographics, in Europe. On the continent, the

Impact of WWI on European Society Essay Example | Topics and Well Written Essays - 750 words

Impact of WWI on European Society - Essay Example This paper briefly analyses the impacts of WW1 on European society. The total deaths of all nations who fought in the WW1 are thought to have been 8.5 million with 21 million being wounded.  Alongside these statistics, was the fact that vast areas of north-eastern Europe had been reduced to rubble. Flanders in Belgium had been all but destroyed with the ancient city of Ypres being devastated. The homes of 750,000 French people were destroyed and the infrastructure of this region had also been severely damaged. Roads, coal mines, telegraph poles had all been destroyed and such a loss greatly hindered the area's ability to function normally (The Treaty of Versailles). Apart from the 116,000 American soldiers, all the other soldiers killed in the WW1 were from Europe. In other words, Europe suffered heavy casualties as a result of WW1. It should be noted that along with the loss of lives, Europe faced a lot of destruction of its properties. The return of war prisoners after WW1 caused many social problems in Europe. Millions of Europeans were in jails after WW1. They forced to spend longer periods in jails even after the end of WW1. Decades after the end of WW1, they got freedom and their return caused new social problems in Europe. â€Å"Emaciated and physically broken, they experienced psychological and material difficulties adjusting to normal life. Their spouses had often remarried. The state aid they received after the release was insufficient and they failed to get new employment† (Paxton, & Hessler, p.472) â€Å"The birth rate in Northern and Western Europe declined by one half after the WW1† (Paxton & Hessler, p.18). It should be noted that the birth rate reduced considerably after WW1 since European couples were either separated after the war or failed to engage in sexual activities because of the physical and psychological trauma caused by this war. Moreover, European women forced to come out from kitchens and work in the factories just l ike men after WW1. They started to lead a more independent life after WW1 (Paxton & Hessler, p.20). Such free life helped them to avoid pregnancy and forced sexual activities. The 1919 Treaty of Versailles was instrumental in ending WW1. It was signed on 28 June 1919. This treaty created a lot of controversies in Europe, especially in Germany. It puts the entire blame on Germany for causing WW1. It forced Germany to concede many of its lands and pay heavy compensation to certain countries. The "Big Three" (David Lloyd George of Britain, Clemenceau of France and Woodrow Wilson of America) were responsible for the preparation of the clauses of Treaty of Versailles. The Big Three were keen on humiliating German feelings as much as possible. In fact, they were concerned about the rise of communism in Europe and they tried to block the spreading of communism in Europe through this treaty. Some people believe that the controversial clauses in the Treaty of Versailles were the exact reason for the occurrence of WW2. Hitler, through his inspirational speeches, injected nationalism in the veins of Germans. He argued that German culture is superior to other cultures and hence Germans have the right to rule the world. He had pointed out that the allied powers caused shame to Germans while forcing them to accept the responsibilities of WW1. In short, the end of WW1 actually prepared a way for WW2.  

The analysis of Young goodman Brown Essay Example | Topics and Well Written Essays - 750 words

The analysis of Young goodman Brown - Essay Example For instance, he introduces Young Goodman Brown, whose name is allegorical in several manners. In addition, this is the title that he gives this narration, which is also a significant part in this narration. There are three allegories in this protagonist’s name that have individual meanings. First, there is the name Young, which seems to suggest the innocence of his character. However, this innocence is later corrupted by several factors that surround this protagonist. The second name is Goodman and is equally significant in an allegorical manner. Careful analysis of this narration reveals that there are few righteous deeds in this narration hence some irony (Neary 445). Consequently, the wife of the protagonist has an allegorical name: Faith. This name suggests hope for several significant things in the narration. In addition, the protagonist needs faith in order to survive the journey he takes through the forest. Consequently, Faith acts as a guardian to the protagonist throughout the narration. Further, Faith is his wife hence presenting a physical guide in the material world, which they live in. In particular, she pleads with the protagonist not to take the evil journey, which would later compromise his spirituality (Hoffman 98). The forest represents all the evil in the narration by Hawthorne because of its components. For instance, it has such tings as trees and wild animals that are synonymous of evil. According to Xian-chun(56) the forest is similar to the mind of the protagonist who struggles to fight evil. In addition, his mind has similar uncertainties to the ones, which people experience in any forest. Traditionally, forests are dark because of the overlapping of trees and other plantations. Similarly, Brown’s mind is dark since it has. Evidently, this forest is ruled by the devil like Brown’s mind, which compromises his spiritual actions

Managerial Applications of Technology (Emerging IT Trends) 1 Assignment

Managerial Applications of Technology (Emerging IT Trends) 1 - Assignment Example This reduces an organization’s operation cost. In business, it is clear that when it comes to technology the entities that adopt a technology first are always the highest beneficiaries of the technology. This is because by the time the other organizations start adapting the new technology they would have already integrated the new technology into their system. By integrating a technology first a business organization, a business organization will be able to gain a competitive advantage over their competitors. It is therefore advisable for a business organization to adopt new technologies as early as possible (Alam, 2014). However, this should come after serious considerations and research on whether the technology in question will be of any benefit to the business organization. The risk involved in early adaptation is that it is always a big gamble with no assurance of the effectiveness of the technology. The other consideration regarding emerging trends in information technology is that a business organization might decide to prototype a technology before actually adopting it. This will enable them to know if the technology will actually be viable for the organization (Brunetti, 2014). However, the negative thing about prototyping is that it can sometimes be

Politics, Society and Business in the New Europe Essay

Politics, Society and Business in the New Europe - Essay Example Germany's employers increased vulnerability to conflict that showed up centralized bargaining agreement and its effects will distabilize its system in the longer term (Steele,2005). Because globalisation pushes all countries toward neoliberalism and deregulation, encouraging firms to lower labor cost and increase labor market flexibility, (Thelen, 2003) which result to distabilization of Germany's economy. It would create trouble between employer and union e.g. labor strike and lockout in some companies if the problem will not be resolve . Besides, the state could no longer depend the welfare of their citizen because in globalization it is the multinational who is powerful. They are the one who detates the state in the removal of some Tariffs, Regulations, Certain Standards, Laws, Legislation and Regulatory measures and the restriction of capital flows and invesment. Germanys' were able to realized that the rich (multinational) grow richer and the poor grows poorer around the world. In otherwords, globalization is beneficial only for those who prososed the theory like the first world countries. ... manys' as second world exporter their employers are trying to come up a bargaining agreement to sustain economic activity by maintaining labor peace and closure or lockout of some establishment.. Martinez and Garcia (Cited by Shah,2007), revealed that there are five (5) points in neoliberalism as follows: 1. The rule of Market- freedom of capital, goods and services these is to trickle down of "Wealth distribution." It is the deunionizing of labor forces and removals of any impedements to capital mobility regulated by the state or government. 2. Reducing public expenditure for social services e.g. health and education, by the government; 3. Deregulation to allow market forces to act as a self-regulating mechanism; 4. Privatization of public enterprise ( things from water to even internet); 5. Changing perceptions of public and community good to individualism and individual responsibility. Robbins and Bacon (Cited by Shah, 2007) pointed out five (5) principles of ideology of neoliberalism: 1. Sustained economic growth is the way to human progress; 2. Free markets without government "interference" would be most effecient and socially optimal allocation of resources; 3. Economic globalisation would be beneficial to everyone; 4. Privatization removes inefficiencies of public sector; 5. Government would provide the infrastructure to advance the rule of law with respect to property rights and contracts. Gounet (n.d.) stated six (6) characteristics of neo-liberalism /competition/free trade and laissez-faire as follows: 1. Bourgeois ideology preponderates by awakening industrial capitalism against feudality and parasitism by abolishing the previleges, for free competition, free trade and laissez faire to bring about wealth. 2. Age of mondialisation is the

Practical Business Analysis Essay 1. Re-do all problems in Practice Problem Set 1. 2. Dollar Car Rental Co. was originally named Dollar a Day Car Rental because they charged $1.00 per day to rent a car, plus a charge per mile driven. Many customers complained that the odometers on Dollar’s cars recorded more miles than were actually driven. To evaluate these complaints you take a random sample of 6 Dollar’s cars, drive them on a carefully measured 100-mile course, and record the miles driven as registered by the odometers. The results are 100, 105, 109, 102, 107, and 101, with the sample standard deviation around 3.578. a. Using these sample results, construct a 95% confidence interval for the population mean miles recorded by all Dollar cars for a 100-mile trip. b. As a legal consultant hired by the group of the customers who complained about the odometers, do you have enough evidence to support your clients’ claim? State your hypotheses (H0 vs. Ha), rejection region and both statistical and substantive conclusions. 3.

The values of the relevant variables were observed for a period of 40 quarters. When the data were run on STATGRAPHICS PLUS, the accompanying printout was created.

Analysing and Applying Business Process Reengineering

Analysing and Applying Business Process Reengineering In the first part of this assignment the meaning of business process reengineering (BPR) is analysed. In more details, it is outlined how business processes might be reengineered to improve company or organizational performance. The themes covered are: The importance of BPR in organizations The objectives of implementing BPR The specific techniques that can be used (like process mapping) The required training The possible problems in implementation (like resistance) As about the second part, a critical evaluation is made concerning the statement of McCabe (2004: 851): BPR does not challenge hierarchical authority, but instead attempts to reconfigure authority and power relations so as to obscure them through the language of consensus. In this section of the assignment it is critically evaluated the proposition that BPR in fact does very little to question the fundamental tenets of hierarchical control and in several important respects simply reinforces them. ANALYSIS OF PART 1. The term of BPR Today the business world is characterized by unpredictable changes, under the global competition and the customers demands. To be successful in such an environment, a firm must operate with speed, flexibility, low overheads and a clearly defined customer focus. The term business process reengineering (BPR) refers to an approach that is used by organizations seeking improvements in their business performance (Anonymous, 2007). The importance of BPR There is a series of driving forces, which trigger companies to undertake reengineering projects. These are customers, competition, change, cost, technology and shareholders and they lead to a requirement of new organizational structures and an alteration of the traditional way of doing business. Organizations consider BPR as an important tool of organizational improvement, as it helps them achieve the radical change necessary for todays volatile business environment. Additionally, BPR stresses the importance of linkages within an organisation. Though its structure integrated processes are generated concerning the nature of peoples jobs and how people are grouped and organized in the working environment. What is more, through BPR peoples jobs become multidimensional instead of narrow and traditional task orientation. When the concept of process is promoted in the BPR, cross boundary teamwork is incorporated and process shifts the goal focus on performance measurement and managerial r esponsibility from a function or responsibility center to an activity derivative process concept. So, BPR defines process teams as an important element in the business environment where work becomes multidimensional, substantive and more rewarding (Anonymous, 2007). It can be concluded that the importance of BPR is found at the fact that it is a dynamic tool for improving operations. BPR provides a process view of the organisation and a way of improving processes. Using this approach a company will be organized based on processes. As a result, processes are simplified, flows are improved and non value added work is eliminated (Schroeder, 2000). BPR is a complete life cycle approach. This provides the scope for problem identification and also solutions to implement the successful business operations. BPR can significantly improve cost, quality, service and speed simultaneously, so important results are provided to customers (Thyagarajan and Khatibi, 2004). It can be supported that organisations should focus on BPR for three key reasons: Firstly, there is much to be gained by improving business process. Secondly, business processes can be controlled and finally business processes are comparatively more important than production processes (Anonymous, 2007). The objectives of BPR BPR is a fundamental element in improving business performance and profitability. The BPR objectives refer to: improved operational performance, by closing performance gaps improved competencies, by closing skill and competency gaps reduced costs and manpower savings, by application of management analysis tools and techniques improved customer services or employee quality of life increased customer satisfaction increased productivity in the workplace continuous improvement of services quality delivered quality goods at competitive prices in a timely fashion (Anonymous, 2010a). The technical tools used in BPR There are different improvement techniques that can be adopted to analyse the BPR. These techniques enable the organization to understand, simplify and improve processes that already exist, not only to meet, but also to exceed the expectations of customers and provide a coordinating discipline for overall performance improvement (Anonymous, 2007). The selection of technical tools for BPR depends upon: (i) the nature of decision areas, (ii) the nature of data to be analysed, and (iii) the background of users. Table 1. The specific techniques that can be used in BPR Areas to be reengineered Techniques used in BPR BPR strategies Decision support system and Knowledge-based models Business process system design Analytical models such as queuing and simulations models Project management PERT/CPM and Flow Charts Reengineering business process Activity-based analysis and workflow model including flow chart Design of information system for reengineering business process Object-oriented models and programming Understanding of the business process system IDEF Models, EFQM Models, Petri-Net Models (Gunasekaran and Kobu, 2002). Process Mapping is a technique known as Process Charting or Flow Charting and is one of the oldest, simplest and most valuable techniques for streamlining work. It is one of the fastest ways to lower errors, increase productivity and affect customer service. It generally follows these steps: Choose a process. Assemble a team. Map out the way work is currently done. Identify problem areas. Brainstorm solutions. Evaluate action steps. Assign responsibilities. Create a master plan. Follow through. (Anonymous, 2010b). Process Mapping is an important tool in examining work flow and customer supplier relationships, which is the foundation for appropriate improvements. Additionally, it is a cost effective training tool for everyone interesting in increasing the efficiency of their organization and improving communication. (Damelio, 1996). Many organizations use this technique as a part of their reengineering projects, as it provides a variety of benefits (figure 1). Figure 1. The main benefits of implementing process mapping technique (Image available at the website http://www.google.gr, accessed 8-10-2010) The BPR training Implementing successfully BPR in an organisations environment is not an easy task, as the appeared changes require changes in attitudes and deep involvement of workforce both in individual and team level. As a result, the fact that a major aspect of BPR is human factor, it makes obvious that appropriate training is required in order to implement successfully BPR in the business environment. Companies should ensure that their employees are suitably motivated and the technology required for training is available in implementing BPR. Training is one of the most frequently used approaches to changing the organisations mindset. A company might offer the suitable training programs so as to effectively implement BPR processes (Daft, 2006) According to White (2010) business process reengineering education and training can come in a variety of ways, including: Learning more about process design at a graduate level. Using online continuing education options for further education. Attending seminars that cover various aspects of business process reengineering. The possible problems in BPR implementation Various radical changes occur when BPR takes place. Hammer and Champy (1993, cited in Anonymous, 2007) have listed the various kinds of changes that occur when a company re-engineers its business process. A shift from functional departments to process teams Job change A reversal of the power relationship: from superordinate to subordinate empowerment . Today markets are characterized by a high flow of information and companies face competitive business environments. Under this reality, organizations must follow effective strategies concerning change management (Robbins, 2001). BPR has to do with improving company or organizational performance, so its implementation requires the changes mentioned above often in a rapid way of implementation in attitudes and deep involvement of workforce both in individual and team level. These changes often refer to redefinition of charts structure and/ or redesign of the workforces roles and responsibilities. The new situation can bring resistance to change, so managers should examine carefully the way BPR implementation will take place. Managers should support understanding and trust concerning the new situation and minimize uncertainty within the workplace. The suggestions for dealing with the possible resistance to change are the following: Determining the goals of BPR implementation. Establishing a clear view about the changes that will occur in the workplace. Applying a direct communication method between managers and employees Checking the procedures of re-engineering, so as to deal with possible problems and find solutions. Focusing on performance measures and compensation shifts Enhancing customer focus as about value change Showing an appropriate management behaviour, through control and supervision Under these suggestions the changes in the business process, lob and structures, management and measurement systems, values and beliefs will result in a flatter organizational structure. As a consequence all the aspects (people, jobs, managers and values) are linked together and the organization will become more responsive in BPR implementation (Anonymous, 2007). ANALYSIS OF PART 2. In this section it will be critically evaluated the statement of McCabe (2004: 851): BPR does not challenge hierarchical authority, but instead attempts to reconfigure authority and power relations so as to obscure them through the language of consensus. In order to make this evaluation, it is essential to introduce the issue of hierarchical authority in an organizations environment. Hierarchical structures are present in most organizations today. Smaller organizations may have only two levels, while larger ones may have a vast number of levels. These structures are used as a method of communications and as the lines of authority. In an organizational environment, the hierarchy mainly apart of a singular/group of power at the top with subsequent levels of power beneath them. Members of such structures chiefly communicate with their immediate superior and with their immediate subordinates. Hierarchical authority structures are providing the opportunity for greater decision-making width for individuals and more flexible definitions of job activities. This is a challenge to existing organizational forms (Zhao, Rosson and Purao, 2007). In a hierarchical organisation employees are ranked at various levels within the organisation, each level is one above the other. At each stage in the chain, one person has a number of workers directly under them, within their span of control. A tall hierarchical organisation has many levels and a flat hierarchical organisation will only have a few (Anonymous, 2010d). At figure 2 a traditional hierarchy is given. Figure 2. A traditional hierarchy diagram (Hierarchical Organisation, available at the website http://www.learnmanagement2.com, accessed 18-10-2010) CHIEF EXECUTIVE MANAGER MANAGER MANAGER ASSISTANT MANAGER ASSISTANT MANAGER ASSISTANT MANAGER STAFF STAFF STAFF STAFF STAFF STAFF STAFF STAFF STAFF It is obvious that hierarchies within control systems are a clear need for business environments. Without some form of hierarchy, a low level of control can create numerous problems in an organization. There ate two kinds of control systems: flat and hierarchical. Hierarchical architectures have a more indirect coupling of perceptions to actions through a hierarchical control structure. Both kinds of control systems have benefits, but hierarchical structure can support faster learning and a better way to deal with resistance to change (Digney, 1998) Control is a fundamental managerial function. It is the process of regulating organizational activities so that actual performance conforms to expected organizational standards and goals and ensures that necessary corrective action is taken. In fact, control is ensuring work accomplishment according to plans. It is a process of ensuring that activities are producing desired results. We can support that control is an executive function involving three elements, i.e., standards, evaluative and corrective action. BPR is the latest wave in a series of management initiatives to increase managerial control (Gupta, 2010). According to the issues covered in the analysis of part one of this assignment, business process reengineering is proved to be a revolutionary, radical change approach to improving organizational performance through transformation. BPR methodologies aim for a flatter organizational structure, promoting the development of empowered process workers who are encouraged to use information technology in radically new ways to carry out business operations. In BPR approaches, empowerment is inflicted by leadership changing worker values and through the use of information technologies enables managerial control. Empowerment through BPR does not necessarily release control but does change the way control is exercised. Authority is still enforced through hierarchical control of culture. The reengineering approach polishes the management of power relations, when attempts are made to change traditional power structures and everyday power relations through the flattening of the hierarchy (Sayer an d Harvey, 1997). The introduction of reengineering introduces a new relationship of power in the form of a discipline which the reengineering sustains through discourse control. In this new situation any discipline comes with its structures, its hierarchies, its inspections, exercises and methods of training and conditioning (Foucault, 1980, p. 158). BPR is an approach that supports transformation with the notion of producing the flatter organization. Hierarchy and control are still promoted and within BPR, the emphasis lies on changing the formal patterns and using mechanisms of control to change the informal (Sayer and Harvey, 1997). BPR is a strong tool of managerial control. Controlling is the fourth function of management process (the other functions are planning, organizing and leading). Through BPR managers can identify whether the organization is on target towards its goals and can make better corrections if necessary. In BPR, information technology is generally considered as playing a role as enabler of new forms of organizing and collaborating. New information technology can help managers provide needed organizational control without strict top down constraints. A representative example is that of Cisco Systems: By using information technology to coordinate and monitor several aspects of operations, the company keeps tabs on employee and organizational performance without maintaining daily authoritarian control over workers. Cisco employees have amazing freedom to make decision and take actions, but they also know that top managers keep a close eye on what is going on throughout the company (Daft, 2006). Most businesses try to take advantage of BPR concerning dealing with the fundamental tenets of hierarchical control. BPR assumes radical redesign of business processes. Many processes simply can not be further improved in small steps and require a complete redesign in order to improve them in a major way. Hierarchical control is a fundamental element in this effort and managers who desire to organize around outcomes, have people processed their own information, put the decision point where the work is performed and build control into the process, should support the view that BPR can reinforce the fundamental tenets of hierarchical control. BPR is a management system of forced, speedy culture change, highly linked to hierarchical control. In fact it does very little to question the fundamental tenets of hierarchical control and in several important respects simply reinforces them. CONCLUSIONS Business Process Reengineering includes changes concerning both structures and procedures defined in a business environment. Human, organizational, technological dimensions that characterize an organization can change through BPR. Using this approach, organizations can seek improvements in their business performance. As it was analysed at the first part of this assignment, organizations consider BPR as an important tool of organizational improvement, as it helps them achieve the radical change necessary for todays volatile business environment. Additionally, BPR stresses the importance of linkages within an organization. What is more, through BPR peoples jobs become multidimensional instead of narrow and traditional task orientation. In result, the importance of BPR is found at the fact that it is a dynamic tool for improving operations. BPR is a fundamental element in improving business performance and profitability. The main BPR objectives refer to improved operational performance, improved competencies, reduced costs and manpower savings, improved customer services or employee quality of life, increased customer satisfaction, increased productivity in the workplace, continuous improvement of services quality and delivered quality goods at competitive prices in a timely fashion. There are different improvement techniques that can be adopted to analyse the BPR. Among them, Process Mapping is a technique known as Process Charting or Flow Charting and is one of the oldest, simplest and most valuable techniques for streamlining work. It is a cost effective training tool for everyone interesting in increasing the efficiency of their organization and improving communication and is highly preferred by enterprises today. Implementing successfully BPR in an organisations environment is not an easy task, as a major aspect of BPR is human factor. So, companies should ensure that their employees are suitably motivated and the technology required for training is available in implementing BPR. Various radical changes occur when BPR takes place, so managers should carefully examine the strategies in change management so as to achieve the best efficiency and deal appropriately with the possible resistance to change that BPR will bring. The second part included a critical evaluation of the statement of McCabe (2004: 851): BPR does not challenge hierarchical authority, but instead attempts to reconfigure authority and power relations so as to obscure them through the language of consensus. According to the relevant analysis, within control systems are a clear need for business environments. Without some form of hierarchy, a low level of control can create numerous problems in an organization. Hierarchical structure can support faster learning and a better way to deal with resistance to change, so BPR supports the management initiatives to increase managerial control. . In BPR approaches, empowerment is inflicted by leadership changing worker values and through the use of information technologies enables managerial control. Empowerment through BPR does not necessarily release control but does change the way control is exercised. Most businesses should try to take advantage of BPR concerning dealing with the fundamental tenets of hierarchical control. This is because BPR is a management system of forced, speedy culture change, highly linked to hierarchical control. In fact it does very little to question the fundamental tenets of hierarchical control and in several important respects simply reinforces them.
