E-Commerce Business Models & The Ever Changing Environment Unbelievably, the E-Commerce Business models are probably the most discussed and least understood aspect of the Internet. In the simplest form, a business model is the method of doing business by which a company can sustain itself while generating positive revenue. Internet will give rise to new kinds of business models. The Internet business models continue to evolve on a daily basis. The models could be implemented in a variety of ways. Furthermore, a company may combine several different models as part of its overall Internet business strategy. For example, it is not uncommon for businesses to blend customer service with a marketing model. Business models have taken on greater importance recently as a form of intellectual property that can be protected with a patent. Indeed, business models have fallen increasingly within the realm of patent law. A number of business method patents relevant to e-commerce have been granted. But some of the more noteworthy patents may be challenged in the courts. Some questions that arise are as follows: Which models will prove most effective for which kinds of businesses? How can each be pursued most effectively? What combinations of the pure models tend to be particularly effective and which tend to be in conflict? It is understood that each of the business models should be applied to a Web site under centralized management. Here are some important example of E-commerce business models: Â · STOREFRONT MODEL: An organization offers products or services for sale. Many Web sites of this sort also have Customer Service Model features, and if not then probably they should have.

Sicko Assignment Example | Topics and Well Written Essays - 500 words

Sicko - Assignment Example After seeing how well the universal healthcare programs worked for the people in Canada, England, France and Cuba, I would have to say that the program should become a norm for the United States as well. I truly believe that if it is implemented in the same manner as in those countries, then the system would actually work for us. Since we are already paying one of the highest taxes in the world, why not actually make that money work for the people paying for it by covering their healthcare costs? Granted that the cost subsidies would put the health insurance companies out of business and maybe the doctors will earn less under the system, but isnt the idea of healthcare to â€Å"help† people become well or prevent their illnesses? Isnt it the job of doctors to â€Å"do no harm† under the Hippocratic Oath? None of that is happening under the American system of healthcare at the moment so yes, it may not be cost-effective for the bottom line of the insurance companies and doctors who are used to fleecing their clients, but it is what will be in the interest of their patients and should therefore be done for them. I would definitely like to initiate the British form of universal healthcare in America. That is because nobody is turned away from the hospitals, the care is given without question, and the medicine is subsidized at a flat rate cost that is affordable to the working class and free to the retirees and jobless who do not stop needing medical care or medicines just because of their age or situations. That is why I would definitely be willing to sacrifice the quality of the healthcare for the quantity of the healthcare. Imagine, being able to get the tests that you need albeit in a schedule in Canda, while you need to wait for health insurance approval for the test in the United States and most likely get denied the procedure anyway. It seems like a no-brainer in that instance. The test will get done, you just need to wait your

Description of the Hawthorne Studies and What Were the Results Research Paper

Description of the Hawthorne Studies and What Were the Results - Research Paper Example At the beginning of the 20th Century, large businesses in America began the adoption of scientific management, an idea initiated by Fredrick Taylor. His idea involved the division of tasks into small portions that would be done by the employees like automatons. These studies have varied to include the effects of the physical environment on the workforce in an effort to ensure maximum productivity. Western Electric Company conducted studies in their Hawthorne plant to establish the relationship between productivity and the influence of the physical conditions. The initial studies began around November 1924 where they evaluated the social effects as well as the experimenter effects. Elton Mayo, who became a professor of industrial research at Harvard later on, supervised the studies (Mayo 64). The initial studies focused on the influence of lighting on the productivity of the workers. Two groups of employees were involved in this study; one group’s lighting was varied while the control group’s lighting remained under the same conditions. When light remained constantly unchanged the two groups demonstrated the same level of productivity. Lighting in the test group was reduced, a situation that raised complains among the group members (Steven and John 5). To further demonstrate the effect, the researchers changed the bulbs daily in the presence of the workers. Despite the bulbs replaced being the same, some improvement in productivity was noticeable in the test group. The findings were that the group with improved lighting demonstrated an improved productivity compared to the control group. In explaining the findings, the researchers concluded that the workers felt motivated by the changes. To the workers, the change was a demonstration that the management was concerned about them. The mental stimulation that they were being treated in a special way encouraged them to be active in their work. Another study was conducted in the relay assembly Test Room using six workers who had worked for the company for some time. Five of them were set to work in the assembling area while the sixth was to supply them with the parts they would require. The study was to focus on the effects of changing the working arrangements on the employees’ productivity (Gale 439). The researchers introduced various variables such as breaks, reduced working hours, and provision of food during the breaks. The breaks were varied, initially they were introduced to two-five minutes break that was done according to their suggestion. This was later changed to two-ten minutes breaks, during this period productivity was seen to improve. Consequently, the researchers adjusted the breaks to six-five minute breaks, these did not go well with the employees, they complained and their total productivity that was measured by the total output reduced (Franke and Kaul 625). Reduction of the total working hours by thirty minutes depicted an increased level of productivit y, further reduction showed an increase in hourly output but the total output per day was drastically reduced. The researchers concluded that the feeling of the employees was that their work was being checked individually. Therefore, the workers were motivated by working as a group, having supervisors that were concerned about their welfare and having a special treatment in the workplace. Another aspect under observation was the social effect and its influence on productivity. This study was done in a bank wiring room where the workers were subjected to the assembling of telephone switching equipment, a task that involved the processes of wiring, soldering, and inspection. At the initial stages of the study, the workers were not open to the observer and had limited

Antitrust practices Essay Example for Free

Antitrust practices Essay Antitrust practices are practices carried on by businesses that end up destroying perfect competition in the market. Antitrust laws are laws prepared to seek and promote healthy market competition by preventing anti-competitive practices by companies. Some of the illegal practices that constitute to antitrust behavior include corporate mergers, monopolies and price fixing conspiracies (Bailey, 2010). The Clayton Act of 1914 was passed by the U.S Congress. It was an antitrust law that was amended to stop and prevent practices that led to unhealthy competition in the market. The Clayton Act was amended in order to complement an earlier version of the antitrust law referred to as the Sherman antitrust Act of 1980. This was a federal law that sought to prevent practices that were harmful to consumers such as cartels, monopolies and other unfair business practices (California Association of REALTORS, 2005). Google Company One of the recent firms to be investigated for antitrust behavior is Google Company that leads the online searching industry. According to Weiss (2014), the firm recently was being investigated by Competition Commission of India (CCI) for claims that it abused its dominance in the online search engine industry by mainly promoting its own services over those of its rivals. This reason is considered to create unhealthy competition in the business as the search engine company dominates its rivals in what is considered almost a monopolistic market. Antitrust behavior brings about both pecuniary and non-pecuniary costs. Since it damages healthy competition in the market, monopolies can result and this has adverse effects to the prices of commodities. The products end up becoming costly and expensive for the customers and, therefore, affecting the society negatively (Bailey, 2010). On the other hand, antitrust behavior leads to the output of products falling below the market competitive le vel and this is mainly witnessed in monopolistic markets. Then again, the antitrust practices can be costly for any company that has engaged in them since if investigations prove that the company is guilty of the said acts then heavy penalties can be imposed on them. Furthermore, this can ruin the reputation of any company and, therefore, ending up losing its customers (Bailey, 2010). Monopolies and  Oligopolies Monopolies and oligopolies are not always good for the society. Their presence in any market simply means they have all the power to control the prices of their products and services. This is not favorable to the customers since prices can always go up any time especially when the demand for certain commodities is high. One good example of an oligopoly is the Coca Cola and Pepsi Companies. These are the world’s largest beverage companies and demand for their products is never decreasing. However, these two companies represent a market with few suppliers while the consumers are many. They have all the power to dictate their products’ prices and the consumers have no power whatsoever (Hovenkamp, 2011). On the other hand, some government monopolies can be considered beneficial to the members of the society. Many governments in the current world control the production and supply of electricity and other forms of energy. This is useful because the governments aim at providin g such services to the citizens at affordable prices and across the countries. It is the responsibility of the government to enhance infrastructure development in the country and, therefore, running such sectors of the economy can be beneficial to consumers. Conclusion In conclusion, it is important to point out that antitrust practices are unwanted behaviors since they destroy healthy competition among businesses. However, the law is strict on companies that engage in these practices and heavy penalties can be imposed on them. Antitrust practices include price fixing, corporate mergers and creation of monopolies (Reeves, 2010).

Essays on Movies (Films) - Stephen Spielbergs Schindlers List :: Movie Film Essays

Essays on Movies (Films) - Stephen Spielberg's Schindler's List    "I know that the great tragedies of history often fascinate men with approaching horror.   Paralyzed, they cannot make up their minds to do anything but wait.   So they wait, and one day the Gorgon devours them,   But I should like to convince you that the spell can be broken, that there is an illusion of impotence, that strength of heart, intelligence and courage are enough to stop fate and sometimes reverse it." Albert Camus.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Albert Camus believes that the greatest tragedies of history are so horrific that people stand in awe, and consequently, nobody even attempts to do anything in response of the tragedies.   Many are under â€Å"an illusion of impotence† , and eventually, Camus states, â€Å"The Gorgon devours them†.   Also, in order for this â€Å"spell to be broken†, people must   have â€Å"strength of heart, intelligence and courage.†Ã‚   I believe that Albert Camus is correct, people are under a vale of impotence when it comes to the tragedies of the world, and that people can easily overcome this inability and reverse their fate, or let the â€Å"Gorgon† devour them.   Camus's beliefs can be proved through the use of examples from the movie Schindler's List.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Oscar Schindler, the movie's main character, is, in the beginning of the movie, not actually aware of the full extent of the killing of Jews and the powerful anti-Semitic outlook of his comrades.   His ties relating to the affairs of the Nazi party and his loyalty to his country shield him from this knowledge. Thus, it can be concluded that in the beginning of the movie Schindler does not fully grasp the tragedy at hand, and consequently does nothing attempt to aid the Jews.   Shindler's realizations of the horrors of the holocaust begin in one scene near the middle of the film.   During this infamous turning point of the movie, Schindler, on top of a barren hill, traces the path of a young and helpless Jewish girl who wanders haphazardly through the streets of a devastated camp.   In a red trench-coat-coat, nowhere to go, desperately searching for her two parents, the little girl finally wanders into an abandoned building where she is safe from the chaotic world outside.   Her safety is only temporary, for later she will be hunted down and cold heartily murdered, forgotten to the world, destroyed by her own people, asking in wonderment, why do I deserve such punishment?      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This scene is the point at which Schindler becomes infuriated, and he asks himself why, and most importantly, what he could do to stop the massacre.

Band of Brothers: E. Company, 506th Regiment, 101st Airborne From Normandy to Hitler’s Eagle Nest, Book Analysis Essay

Book Report â€Å"Band of Brothers: E. Company, 506th Regiment, 101st Airborne From Normandy to Hitler’s Eagle Nest† by Stephen E. Ambrose Band Of Brothers is the history of Easy Company, 506th Parachute†¨Infantry Regiment, 101st Airborne Division, from basic training to†¨D-Day. It follows the jump into Holland, the Battle of†¨the Bulge, and finally the occupation of Berchtesgaden and Austria. This is a rarity among military histories, told from the viewpoint†¨of the front line soldier, the privates, non-commissioned officers and officers who†¨carry out the grand strategy of generals. Many books†¨discuss the inner working of commands at Division and Army levels, but few detail the day to day life of the†¨soldier. Stephen Ambrose’s book does that and†¨more. It explores the how draftee citizen soldiers of†¨elite outfits like the 101st Airborne did, in World War II, defeat†¨an enemy like the well trained German Wehrmacht and S.S. In 1942 the Second Battalion of the 506th was formed and started†¨basic training. The recruits volunteered for the thrill, the honor, the extra money, but above all the desire to be better†¨than the ordinary draftee. A description of the physical effort†¨required in basic training explains why a majority of the†¨volunteers never made it as far as the door of the airplane. When†¨the Company finally made it to Fort Benning for jump school, they†¨were in such great physical shape that they outdid the school’s†¨physical fitness cadre. After five jumps in December of†¨1942, the company qualified as Parachutists, and nine-months later†¨they were on a ship to England to train for the invasion of†¨Hitler’s Fortress Europa. Ambrose also details the nine months of training that the company†¨endured in England in preparation for the invasion. He†¨tells it from the viewpoint of both officers and men and explains†¨the final shift in Easy Company hierarchy just prior to D-Day. His†¨description of the night jump of the 101st in the early morning†¨hours of June 6, 1944, with men and officers scattered about the†¨countryside, and the confusion, heroism and chaos that surrounded†¨the successful landings at Utah Beach, is masterful. He†¨explains how the few outer roads from the beach are zeroed in by†¨German artillery, and that the job of the airborne was to nullify†¨the artillery and its defending troops. The efforts of Lt. Richard  Winters to fulfill that mission are one†¨of the high points of the book. As the book reports â€Å"By†¨this time, about 0700, E Company consisted of two light†¨machine-guns, one bazooka (no ammunition), one 60mm mortar, nine†¨rifleman, and two officers.† Lt. Winters was in charge. With less†¨than 100 men assembled in the battalion, the commander could only†¨afford to send Easy Company to attack and overrun a four gun German†¨battery defended by a fifty-man platoon. As the book puts it, quoting one of the men, â€Å"Here the training paid off. `We fought as†¨a team without standout stars,’ Lipton said. `We were like a†¨machine. We didn’t have anyone who leaped up and charged a†¨machine-gun. We knocked it out or made it withdraw by†¨maneuver and teamwork or mortar fire. We were smart;†¨there weren’t many flashy heroics. We had learned that heroics was†¨the way to get killed without getting the job done, and getting the†¨job done was more important.† Three hours after the attack†¨commenced, it was completed successfully. Easy Company went on to fight through Normandy until June 29th when†¨it was pulled out of line and sent to a field camp near Utah†¨Beach. They had jumped into Normandy with an effective†¨strength of 139 men and officers and ended up with†¨79. Ambrose’s description of those few days from the†¨night jump to their last fight at Carentan is magnificent. The book next describes the company’s jump into Holland, near the†¨Rhine River, where they fought through November of 1944, and then†¨on to Bastogne, to again become front line troops in the historic†¨Battle of the Bulge. Easy Company was the first Allied†¨troops to occupy Hitler’s mountain retreat at†¨Berchtesgaden. After occupation duty in Austria, the†¨company and battalion were sent back to a small town near Paris,†¨and on November 30, 1945, the 101st was deactivated. As Ambrose†¨puts it, â€Å"The Company had been born in July 1942 at†¨Toccoa. Its existence essentially came to an end almost†¨exactly three years later. In those three years the men had†¨seen more, endured more and contributed more than most men can see, endure or contribute in a lifetime.† Band Of Brothers†¨describe s those eventful three years in such a way as to make the†¨reader experience them too. I think Ambrose did very well telling the story of Easy Company because, as stated above, I felt that I was able to experience the three years very well. I am not much of a reader, but enjoyed reading the book very much. I love American history and I have an interest in the military. Having participated in JROTC in high school for 4 years and  doing ROTC my first year in college, I was able to understand the roles and concepts presented in the book. One theme I saw a lot in the book was the feeling and thought of brotherhood. The title of the book is Band of Brothers and Ambrose did a very good job of conveying the soldiers’ brotherhood through out the book. Starting at the beginning, when they are training, the soldiers’ trained together, worked together, and suffered together. As a team, working together is key, and the soldiers of the 101st Airborne identified that concept early on and kept it strong. One phrase I saw quite a few times was â€Å"follow me†. I think Ambrose included that phrase so much because it shows the leadership and brotherhood. They helped each other and led each other to success and improvement. From the American history perspective, I loved this book! I have been learning about World War 2 for several years now, i ncluding this year in this American History class with the great Keith Maljean, but this is the first time I learned from the soldiers’ perspectives. Ambrose did a phenomenal job of interviewing the members of the 101st Airborne and recounting their stories. Reading the book, I felt like I was right there with them on their first jump, landing in France, and at the first mention of the Airborne division. Volunteering for something new, not knowing what was going to happen. Literally jumping into an unknown, new division of the Army. I embarked with them on the fight to defeat Germany and bring an end to the Nazis. I feel that I gained a better understanding of the American soldier in the World War 2 era, and it is nothing like the American soldier nowadays. Today, our armed forces are facing things that we have seen before, for the most part. Back in the World War 2 era, the soldiers were facing new ships, vehicles, aircrafts, artillery, rocketry, small arms, and biological, chemical, and atomic weapons. It was a very scary time for the soldiers not knowing what was coming or how bad it is. Through the stories in Band of Brothers, I was able to understand what the life of the soldier was like and how they adapted to the new weaponry. When I first heard that I was going to have to do a book report for this class, I was completely dreading it due to my lack of joy for reading and writi ng, but I am glad that I stumbled across this book because I don’t know if I would have been able to find a book as good as this. Stephen Ambrose is a brilliant writer and recounted the stories of the men from the 101st Airborne with great detail. It was entertaining,  informative, and all around life changing. This book reinforced the concept of brotherhood and gave me a great perspective of World War 2 from a soldier’s point of view. I would definitely recommend this book to anyone interested in American History or just looking for a good read.

Olmec Religion - the First Mesoamerican Civilization

The Olmec civilization (1200-400 B.C.) was the first major Mesoamerican culture and laid the foundation for several later civilizations. Many aspects of Olmec culture remain a mystery, which is not surprising considering how long ago their society went into decline. Nevertheless, archaeologists have been able to make surprising progress in learning about the religion of the ancient Olmec people. The Olmec Culture The Olmec culture lasted roughly from 1200 B.C. to 400 B.C. and flourished along Mexicos Gulf coast. The Olmec built major cities at San Lorenzo and La Venta, in the present day states of Veracruz and Tabasco respectively. The Olmec were farmers, warriors and traders, and the few clues they left behind indicate a rich culture. Their civilization collapsed by 400 A. D. - archaeologists are unsure as to why - but several later cultures, including the Aztec and the Maya, were profoundly influenced by the Olmec. The Continuity Hypothesis Archaeologists have struggled to put together the few clues that remain today from the Olmec culture which vanished well over 2,000 years ago. Facts about the ancient Olmec are hard to come by. Modern researchers must use three sources for information on the religion of ancient Mesoamerican cultures: Analysis of relics including sculpture, buildings and ancient texts when availableEarly Spanish reports of religious and cultural practicesEthnographic studies of modern-day traditional religious practices in certain communities Experts who have studied the Aztecs, Maya and other ancient Mesoamerican religions have come to an interesting conclusion: these religions share certain characteristics, indicating a much older, foundational system of belief. Peter Joralemon proposed the Continuity Hypothesis to fill in the gaps left by incomplete records and studies. According to Joralemon there is a basic religious system common to all Mesoamerican peoples. This system took shape long before it was given monumental expression in Olmec art and survived long after the Spanish conquered the New Worlds major political and religious centers. (Joralemon quoted in Diehl, 98). In other words, other cultures can fill in the blanks in regards to Olmec society. One example is the Popol Vuh. Although it is normally associated with the Maya, there are nevertheless many instances of Olmec art and sculpture that seemingly show images or scenes from the Popol Vuh. One instance is the nearly identical statues of the Hero Twins at t he Azuzul archaeological site. The Five Aspects of Olmec Religion Archaeologist Richard Diehl has identified five elements associated with Olmec Religion. These include: A cosmos which identifies the socio-cultural context within which Gods and man interactedDivine beings and gods who controlled the universe and interacted with menA shaman or priest class who acted as intermediaries between the common Olmec people and their gods and spiritsRituals enacted by shamans and/or rulers that reinforced the concepts of the cosmosSacred sites, both natural and man-made Olmec Cosmology Like many early Mesoamerican cultures, the Olmec believed in three tiers of existence: the physical realm they inhabited, an underworld and a sky realm, home of most of the gods. Their world was bound together by the four cardinal points and natural boundaries such as rivers, the ocean and mountains. The most important aspect of Olmec life was agriculture, so it is no surprise that the Olmec agricultural/fertility cult, gods and rituals were extremely important. The rulers and kings of the Olmec had an important role to play as intermediaries between the realms, although it is unknown exactly what relationship to their gods they claimed. Olmec Deities The Olmec had several deities whose images repeatedly appear in surviving sculptures, stonecarvings and other artistic forms. Their names have been lost to time, but archaeologists identify them by their characteristics. No fewer than eight regularly-appearing Olmec deities have been identified. These are the designations given to them by Joralemon: The Olmec DragonThe Bird MonsterThe Fish MonsterThe Banded-eye GodThe Maize GodThe Water GodThe Were-jaguarThe Feathered Serpent Most of these gods would later figure prominently in other cultures, such as the Maya. Currently, there is insufficient information about the roles these gods played in Olmec society or specifically how each was worshiped. Olmec Sacred Places The Olmecs considered certain man-made and natural places sacred. Man-made places included temples, plazas and ball courts and natural places included springs, caves, mountaintops and rivers. No building easily identifiable as an Olmec temple has been discovered; nevertheless, there are many raised platforms which probably served as bases upon which temples were built of some perishable material such as wood. Complex A at La Venta archaeological site is commonly accepted as a religious complex. Although the only ballcourt identified at an Olmec site comes from the post-Olmec era at San Lorenzo, there is nevertheless much evidence that the Olmecs played the game, including carved likenesses of players and preserved rubber balls found at the El Manatà ­ site. The Olmec venerated natural sites as well. El Manatà ­ is a bog where offerings were left by the Olmecs, probably those who lived at San Lorenzo. Offerings included wooden carvings, rubber balls, figurines, knives, axes and more. Although caves are rare in the Olmec region, some of their carvings indicate a reverence for them: in some stonecarvings the cave is the mouth of the Olmec Dragon. Caves in Guerrero state have paintings inside which are associated with the Olmec. Like many ancient cultures, the Olmecs venerated mountains: an Olmec sculpture was found close to the summit of the San Martà ­n Pajapan Volcano, and many archaeologists believe that man-made hills at sites such as La Venta are meant to represent sacred mountains for rituals. Olmec Shamans There is strong evidence that the Olmec had a shaman class in their society. Later Mesoamerican cultures which derived from the Olmec had full-time priests who acted as intermediaries between the common people and the divine. There are sculptures of shamans apparently transforming from humans into were-jaguars. Bones of toads with hallucinogenic properties have been found at Olmec sites: the mind-altering drugs were presumably used by shamans. The rulers of Olmec cities probably served as shamans as well: rulers were likely considered to have a special relationship with the gods and many of their ceremonial functions were religious. Sharp objects, such as stingray spines, have been found at Olmec sites and were most likely used in sacrificial bloodletting rituals. Olmec Religious Rituals and Ceremonies Of Diehls five foundations of Olmec religion, the rituals are the least known to modern researchers. The presence of ceremonial objects, such as stingray spines for bloodletting, indicate that there were, indeed, important rituals, but any details of said ceremonies have been lost to time. Human bones - particularly of infants - have been found at some sites, suggesting human sacrifice, which was later important among the Maya, Aztec and other cultures. The presence of rubber balls indicates that the Olmec played this game. Later cultures would assign a religious and ceremonial context to the game, and it is reasonable to suspect that the Olmec did as well. Sources: Coe, Michael D and Rex Koontz.
