Cybercrime Definition Essay

What is this Cyber crime? We read about it in newspapers very often. Let’s look at the dictionary definition of Cybercrime: â€Å"It is a criminal activity committed on the internet. This is a broad term that describes everything from electronic cracking to denial of service attacks that cause electronic commerce sites to lose money†. Mr. Pavan Duggal, who is the President of www.cyberlaws.net and consultant, in a report has clearly defined the various categories and types of cybercrimes. Cybercrimes can be basically divided into 3 major categories: 1. Cybercrimes against persons. 2. Cybercrimes against property. 3. Cybercrimes against government. Cybercrimes against persons: Cybercrimes committed against persons include various crimes like transmission of child-pornography, harassment of any one with the use of a computer such as e-mail. The trafficking, distribution, posting, and dissemination of obscene material including pornography and indecent exposure, constitutes one of the most important Cybercrimes known today. The potential harm of such a crime to humanity can hardly be amplified. This is one Cybercrime which threatens to undermine the growth of the younger generation as also leave irreparable scars and injury on the younger generation, if not controlled. A minor girl in Ahmedabad was lured to a private place through cyberchat by a man, who, along with his friends, attempted to gangrape her. As some passersby heard her cry, she was rescued. Another example wherein the damage was not done to a person but to the masses is the case of the Melissa virus. The Melissa virus first appeared on the internet in March of 1999. It spread rapidly throughout computer systems in the United States and Europe. It is estimated that the virus caused 80 million dollars in damages to computers worldwide. In the United States alone, the virus made its way through 1.2 million computers in one-fifth of the country’s largest businesses. David Smith pleaded guilty on Dec. 9, 1999 to state and federal charges associated with his creation of the Melissa virus. There are numerous examples of such computer viruses few of them being â€Å"Melissa† and â€Å"love bug†. Cyberharassment is a distinct Cybercrime. Various kinds of harassment can and do occur in cyberspace, or through the use of cyberspace. Harassment can be sexual, racial, religious, or other.

Client-Server Networking Essay Essay

The problem in the given scenario for the user is that the new driver installed to be compatible with the graphics adapter was not downloaded correctly or was incomplete. This is what causes the secondary malfunctions with the screen. When he was seeing the wavy lines it meant that the driver needed to be updated to use the new graphics adapter. He then checked the device manager and saw that it could be updated. He did so and restarted the computer afterwards. As it started he began hearing the noises because the driver was not downloaded correctly. And he then lost the display and could not diagnose the issue properly. In order to resolve this issue you must first restart the computer. As it comes back up from restarting you would put it in safe mode.

Workplace Stress Management Essay Example | Topics and Well Written Essays - 250 words

Workplace Stress Management - Essay Example The work is bound to eventually start suffering since employees become overworked. The agencies can become highly productive by setting up guidelines that underpin reasonable hours of work. It is imperative to allow employees to take requisite breaks and some time off. As such, they are bound to develop a tendency to deliver a higher work output (Girdano, Dusek & Everly 2005). Â  It is important to listen to employee feedback. In most law enforcement agencies, the employees are given a descriptive course of action to pursue by the high command, and as such act in strict confidence of their instruction without necessarily imparting their opinion. Most employees have the feeling that their supervisors have little value for their opinion. Taking the time to listen to employees and outrightly implementing changes that are bound to benefit them is an approach that will see a tremendous decrease in employees’ workplace stress levels since employees ascribe a sense of value attached to them. The employees can contribute to the prodigious success of the agencies which benefit in the long term by gaining a long-lasting workforce that is not bound to easily resign and result in high turnover.

The History of Computer Programming Research Paper

The History of Computer Programming - Research Paper Example Computer programming started in the 19th century, though scientists had started designing several devices such as calculators for various purposes before this period. Charles Babbage designed the first programmable computer in 1835, called the Analytical Engine. The Analytical Engine could be programmed to solve computational problems. Ada Lovelace designed the first program for the Analytical Engine and invented the programming loop and subroutine. Herman Hollerith invented the concept of data recording on machine readable media in the late 1880s. He used punched cards and invented two machines namely the tabulator and keypunch to process the cards (Campbell-Kelly and Aspray 45). In the 1940s, computer coding was done manually and then entered into the system as the systems were slow and had limited memory. Computer programming languages such as Plankalkul, C-10, and ENIAC were developed. A machine called Robinson was developed in 1940 by the British in order to decrypt the messages encrypted using the Enigma machine by the German military during World War II. Z3 was designed in Germany in 1941 by Konrad Zuse. He started developing Plankalkul (Plan Calculus) in 1945, which was the first algorithmic computer programming language. His machines were destroyed during the World War II and only the Z4 survived. Scientists from IBM and Harvaerd designed a programmable computer in 1944 called Mark I (O’Regan 124). In 1945, John Von Neumann invented the concepts of ‘shared-program technique’ and ‘conditional control transfer’. The shared program technique stated that complex instructions should control simple hardware instead of the simple hardware being wired for every program. The conditional control transfer enabled the development of loops with IF, THEN, and FOR statements. This concept also suggested that small code blocks could take any random order instead of the steps ordered chronologically. Von Neumann architecture was invented and it enabled the

Job Design as a Motivational Tool Essay Example | Topics and Well Written Essays - 500 words

Job Design as a Motivational Tool - Essay Example Job enrichment is the practice of enhancing job content by building into it more motivating factors such as responsibility, achievement, recognition, and personal growth (Schermerhorn & Hunt & Osborn). A small business owner depends a lot on the output of their staff since resources are limited. The employees must be empowered by the owner in order to get more out these employees. The job enrichment strategy can be used effectively by proving the employee with higher level of involvement in the everyday activities of the business so that the employee feels that the overall performance of the company is highly dependent of the work the person is performing. Job enlargement increases the variety of tasks by combining two or more jobs into job description that used to be performed by different set of workers. This is a very typical scenario in a small business. Sometimes the accountant is also the marketing executives. The small business owner can use this strategy, but the owner must m ake sure the employee is being compensated adequately in financial terms so that the person does not feel he / she is being exploited. Job rotation is a work layout technique that involves a horizontal approach which involves the periodical shifting or rotating of employees into different job tasks. In small company job rotation occurs intrinsic without the employees noticing the business owner is shifting their job duties. The business need determines the rotation of the employee. Employees get motivated when the manager gives them different tasks to perform because the monotony of repetitive work tasks is eliminated. Employees enjoy working in a place where their time needs are part of the equation. A system that provides the flexibility employees desired is flextime. Flextime is a job design system that allows the employee to select the time he or she will

Pop culture across cultures Assignment Example | Topics and Well Written Essays - 1750 words

Pop culture across cultures - Assignment Example Walt Disney`s personages are often charming, attractive, and mostly traditional: princesses, princes, animals with extraordinary powers, villains. Disney chooses not to risk as Pixar producing films about an old man mourning his late wife or about a lonely robot cleaning the planet Earth from trash. So it was another good old story about a beautiful big-eyed and wasp-waisted princess who was waiting for true love to get rescued. But something went wrong†¦ In a couple of months after the release of the animation film the world got literally infected by â€Å"Frozen†-mania. The name of the main character became one of the most popular baby-girl names in Scandinavian countries and in Britain (not to mention America). YouTube got flooded with the videos in which the whole families, including toddlers and grandfathers, sing the songs from the animation film. I personally was impressed by the video of the head of the school who announced winter vacations with his own variant of â€Å"Let it go†. Children were ready to wait for more than five hours to meet Elza, Anna, and Olaf in Disney World. The hashtag #TheColdNeverBotheredMeAnyway got incredibly popular in so unexpectedly different groups and communities in Twitter and Instagram. The main theme of â€Å"Frozen† got a number of interpretations starting from divorce and autism and ending with the concept of homosexuality and transgender ( Lynskey). The answer why children are obsessed with â€Å"Frozen† seems obvious at first sight. It is the Walt Disney studio, it does not make bad movies, the company invests thousands and millions of dollars to make its animation colorful and realistic and attracts the best composers to create incredible soundtracks. But that is their general policy, and the number of films they produced before â€Å"Frozen† were made according to this high standards. I looked through the movies Disney created last five-six years and realized that I did not know the name of a

INTRODUCTION TO ECONOMICS FOR BUSINESS Essay Example | Topics and Well Written Essays - 2000 words

INTRODUCTION TO ECONOMICS FOR BUSINESS - Essay Example In this context we will look at the costs incurred in the production of Apple’s new generation iPads. The company has basically two models of the new generation iPad models; one that is equipped with 32 GB on NAND flash memory and the other that is equipped with 64 GB NAND flash memory and both with a 4G long term evolution (LTE) wireless capability. These are just but the major brands of the new generation iPads. What stands out is the difference in the price of production of the two different models. Looking at the bill of materials of these two, we find that the new iPad 32 GB carries a total of $364.65 and an additional cost of about $10.75 which covers the cost of manufacturing one unit so that the total bill of materials for this iPad to be at $375.10. The 64 GB one’s bill of materials is just $22.85 more than that of the 32 GB model. Looking at these new models, it is simply the prices of their parts that make them so expensive. â€Å"For instance the NAND flash memory prices range from $16 to $67 and are one of the key profit generating components for Apple in the new iPad line† A. Rassweiler (2012) noted. The iPads display and touch screen are also expensive at $120 according to Andrew Rassweiler (2012) too. Some other parts include the $23 A5X processor manufactured by Samsung and which makes up 6.3% of the total BOM, a $41.50 camera similar to the one installed in the iPhone 4 modules, and an improved capacity lithium polymer battery that cost $32.00per piece. This new battery can support 42.5 watt hours which is about 75% from the previous 25 watt hours in the iPad 2. This new battery costs only about 40% more than the old model which costs about $22.75. All in all, basically the 2nd generation iPads cost about$271.00 to produce, about 9 percent cheaper than the 3rd generation ones. According to IHS iSuppli’s Fred Straker (2012). Apple has chosen to leave the price difference at only $71 in order to make it difficult for any other company to beat the price of the iPad 3 given how expensive its production cost is. The average variable cost of producing these new model iPads is just about $360 which is a very high price per unit produced. This however means that on the other hand Apple won’t be able to make quite the profit margin that it was evidently used to with the sale of every iPhone unit, although they will not be too much at loss as most of their profits will be from the 64 GB versions of the new iPads, that is if they sell. The cost of making a 64 GB version just beats that of making the 16 GB one by about $50, with the retail price difference being over $200 due to the added 4G LTE networking technology. This is basically an upgrade that pushes up the retail price of the 64 GB version way beyond the cost of the actual upgrade. This actually means that the more expensive iPads if sold will comfortably cover for the not so much profits earned by the company through the selling of the sl ightly affordable ones. Specifically the 64 GB8with no 4G and the 16 GB9 up to the 64GB11 are Apple’s most expensive iPads and if sold will earn the highest of profits. These are the models that can earn the company the profit margins they are looking forward to. Also the retail price of the iPad 3 is about $629 and that gives Apple a marginal profit of about 51% which is slightly less than that of the 3G iPad2

The form and function of Concept Store Literature review

The form and function of Concept Store - Literature review Example The subsequent section provides a detailed overview of concept stores, thus giving insight into the inception of this retail store concept and the principal features that characterize it. This chapter also covers the factors that contribute to the widespread adoption of concept stores in the fashion sector, under the key drivers section. Other factors addressed under this literary analysis segment include the format of a conventional concept store, the potential size and popular locations of these retail stores, as well as, the distribution hierarchy adopted by most concept stores. The latter section provides information on strategic function, design or architectural form of a concept store, and the overall language concept of this category of stores. The concluding part of the literature review chapter identifies research gaps that exist in study information available on concept stores, their design and overall operation. The physical environment of a store is one of the principal issues that retailers are supposed to take into account when launching a business venture. This is because it plays a significant role in affecting consumers’ decision to purchase and experience the entire shopping experience. Management of a store’ retail setting, therefore, affects both parties with the store owners’ enjoying increased revenues from enhanced customer loyalty, and shoppers gaining pleasure from the ambient shopping environs. Referred to as â€Å"atmospherics† the concept of managing the physical environs of a store was initially proposed by Kotler (1973). In this case, management of the atmosphere of a store is delineated as concerted effort to conceptualize a design that evokes certain emotions, which increase purchasing probability. Stimuli spurred by in-store setting directly correlates with the amount of pleasure that customers derive from shopping at the store. Ambient aspects related to the physical background of a store usually

Cultural Makeup Of China Essay Example | Topics and Well Written Essays - 1000 words

Cultural Makeup Of China - Essay Example It is essential to outline that there is a significant set of cultural features affecting the business behavior in China. China has a record population of more than 1.3 billion citizens (Fabbi 8). Due to hardworking nature of the Chinese society, a large portion of their population is involved the daily business operations. Based on this, Chinese have been putting most their cultural business practices into use. In addition, fifty-six (56) ethnic groups are officially recognized in the country. These ethnic groups include the Han and Zhuang. The Chinese culture and civilization has been influenced by three main religious movements, which are Taoism, Buddhism and Confucianism. In this sense, China’s prominent religions thus include Islam, Christianity and Buddhism (Alon 24). The country’s demographic values reveal that about 10% of China’s population lives on $1 a day (Fabbi 30). This small value has resulted into most Chinese doing their best to excel in business. 91.51% of the Chinese people belong to the Han ethnic group (Fabbi 12). Of the remaining 55 ethnic groups, only one has a population of over of 1%. This is the Zhuang ethnic group.

In terms of religion, 2% of the country’s population is made up of Muslim while the Christian population stands between 3.2% and 5%. Additionally, Buddhism is practiced by 10% to 18% of the Chinese population. Lastly, 30% of the Chinese practice local folk religions. Since China is an atheist, it officially does not survey its people based on religion. On this regard, the Chinese culture does not consider religion to be of any effect on their respective business behaviors (Fabbi 128). The other sets of crucial Chinese cultural characteristics in business are about prosperous entertainment. A key part of China’s business culture is that evening banquets are

Uses and Gratification Research Essay Example for Free

Uses and Gratification Research Essay The Uses and Gratifications Theory is a famous approach to understanding mass communication. It is an audience-centered approach to media study focusing on the uses to which people put media and the gratifications they seek from that use. (Baran, S. J. , Daris, D. K. , 2006) It emphasizes the audiences rather than the actual message because it more focuses on what audiences will do with the media instead of what media does to the people. Blumler and Katz’s Uses and Gratification Theory recommend media users should take a dynamic role in interpreting and integrating media into their lives because they have alternate choices to gratify their own need. (Uses and gratifications theory) They also take a dynamic part in the communication process and this are the goal oriented in their media use. Uses and Gratification Theory (UG) is a psychological communication perspective that examines on how individual use mass media for satisfy their life but not study on how media impact the audiences. It also emphasizes that motives, actions or an attitude is related to the media use and might change by individual or groups. When an audience actively seeks out for media, they are usually seeking for delight a need. An audience based on theoretical structure to select media and content that can satisfy their needs and desires. (Papacharissi, Z. , n. d. ) The needs will deliver as a motive for adopting particular medium use and this will connected to the social and psychological which make up of the individual. For example, a family may watch a TV shows for instance The American Next Top Model for their entertainment or spend some time together with their family members while some people may choose to browse an internet or look for the magazine content in order to satisfy their information needs. Audience consumes the particular media because they like what they gained from it. However, a number of mass communications scholars have argument about uses and gratifications theory is not a strict social science theory. In reality, Uses and Gratifications perspective has always provided a cutting-edge theoretical approach in the early stages of each new mass communications medium for instance television, radio internet and newspapers as well. Although scientists now are continuously using traditional tools to answer questions about the media use, but we must also be prepared to enlarge our existing theoretical models of Uses and Gratification. Besides that, the theory explains the uses and functions of the media for individuals, groups and the society. At the core of uses and gratifications theory lies the assumption that audience often seek out the mass media in order to gratify their individual needs. (Uses and gratifications approach. ) Audience plays their role differently in seeking out for the medium in order to gain their own satisfaction and needs. Furthermore, medium will be used more when the current motives to use the medium leads to more satisfaction and happiness. Development Uses and Gratifications Theory first advanced in the 1940s by Lazarsfeld and Stanton (1944), attempts to describe the reason of people use on mass media, and also the different kinds of satisfaction they receive from mass media. Gratifications are happiness, satisfactions and rewards, as a result of you meet a specific goal or desire. â€Å"The theory relies on the belief that the audience is not merely a group of passive media consumers, but that they play an active role in selecting different media to meet their needs. (Infante, Rancer Womack, 1997; Lowery De Fleur, 1983) An audience has freedom to choose what media they prefer. For instances, read for newspaper or browser a website in order to meet their desires and goals. In 1944, Herta Herzog researches on the media gratifications and found that there are three major type of gratification towards the radio soup opera which are merely for emotional release, enjoyment for wishful thinking and getting advice from the listening to daytime serial. (Baran, S. J. , Daris, D. K. 2006) In 1961, Wilbur Schramm along with his associates did studies on children and TV which proved that this particular audience was active. It is not the TV lead to an effect on the passive viewers but children selected and watched TV programming in order to satisfy their three needs. There were the need for entertainment, the need for information and the need for social utility. (DeFleur, M. L. , 2010) During 1970s, some media researchers aware that the activeness people of using the media will determine the degree of the effect on that person. For example when a person think that the book have a particular effect on him/her, he/she will work to induce that effect rather than the book induce the learning effect on the person. (Baran, S. J. , Daris, D. K. , 2006) Furthermore, Rubin (1986) stated two underlying presumptions of the uses and gratifications model which explains how people are motivated by a desire to gratify certain needs and also how the audience uses media rather than how the media uses us. Besides, understanding audience consumption patterns will improve understanding of media effect impacts toward audiences. In two separate studies in 1979 1983, Rubin identified six major uses of television for children and adolescents are learning, passing time or habit, companionship, escape, arousal, and relaxation and for adult are passing time, information, entertainment, companionship, and escape. † Five basic assumptions of Uses and Gratification Theory As Katz, Blumler, and Gurevitch give explanation in the book â€Å"Mass Communication Research†, there are five basic assumptions in Uses and Gratifications Theory. (Spring, E. R. 2002) The first assumption is â€Å"the audience is conceived as active. † This idea emphasizes the viewers are goal-oriented and tries to achieve their goals from the media source. This directly reflects the needs of the audience member in gaining the media source. Second basic assumption is â€Å"in the mass communication process much initiative in linking need gratification and media choice lies with the audience member. † This assumption ex plains people use media for their own advantage rather than the media uses them. The receiver confirms what is going to absorb and does not allow the media to influence their mind because the individual opinion is more powerful than what media is portraying. The third basic assumption is â€Å"the media competes with other sources of need satisfaction. † This assumption emphasizes on each individual has different needs and desires. By fulfilling their needs and desires, they have to create a wide range of choices in order to meet these needs. The forth basic assumption which is â€Å"many of the goals media use can be derived from data supplied by the individual audience members themselves. People are very responsive and alert about their motives, choices and able to explain their motives verbally as well. The final basic assumption which is â€Å"value judgments about cultural significance of mass communication should be suspended while audience operations are explored on their own terms. † The theorists believe the audience would able to find out the value from the media content. It is the individual audience members who make the decision to view the particular media. Therefore, they place the value on it by their individual decision to view it. Katz, E. , Blumber, J. G. , Gurevitch, M. , 1974) These basic assumptions provide a framework for understanding the exact correlation between the media and the viewers. Lastly, it provides a distinction as to how the audience is more or less active and the consequences of their involvement in the media as a whole. Literature Review on the Key Findings in the New Era The uses and gratifications theory has been widely used for the studies of Internet as well as Social networking system used. As cited by Hetzog, Katz. 1974), UG suggested that people are consciously choosing the medium that can satisfy their needs and they can recognize their reasons for making that media choices. Maddox (1998) found that the main purpose of people using internet is to gather different type of information which is supported by Lin (2001) that people who need information reception are more likely to use the online services. According to Blumler Katz, (1974), Lasswell suggested that media fulfilled the needs for surveillance, correlation, entertainment and cultural transmission both for individuals and society. The reason for internet usage also associated with entertainment oriented gratification. (Lin, 1996). According to Urista, M. A. , Dong Q. , Day, K. D. (n. d. ), the Wollfradt and Doll Internet Motivation Scale comprise three underlying motives for using the Internet: information, interpersonal communication, and entertainment (Matsuba, 2006, p. 278). A 1995 study of college students Internet usage resulted in six motivational categories: entertainment, social interaction, passing the time, escape, information, and Web site preference (Kaye, 1998, p. 4). Stafford and Gonier (2004) have identified several gratifications from Internet use that motivate users’ behaviors. These include web searching, the acquisition of information, the ability to engage in interpersonal communication, and socialization. As cited by Soh, C. H. (2010), Jaafar and Sulaiman (2005) concluded that entertainment is the primary online activity of home computer users in Malaysia. As the Social network system is more and more popular, there are scholars who investigate it based on uses and gratification theory. As cited by Urista, M. A. , Dong Q. , Day, K. D. (n. d. ), Starkman (2007) has demonstrated that motivations for using the Internet are primarily caused by desires for â€Å"relaxation, fun, encouragement, and status† (p. 211). Ray (2007) explored the multifunctional uses of SNS for simultaneously fulfilling entertainment, information, surveillance, diversion and social utility needs. According to Raacke, J. , Bonds-Raacke, J. (2008), for those who have the Facebook account, many uses and gratifications are met such as keeping in touch with friends. For those who do not have Facebook account, the result indicated failed uses and gratifications for not having a friend-networking site. According to a comparative study between Australia and the Netherlands research, SNS are a very effective means for building and maintaining relationships. Many participants acknowledged that SNS make staying in touch with friends much more convenient, which in turn, increases their motivation for maintaining relationships through communication on SNS. It also showed that there is a link between internet addiction and eroticism Sex differences did occur when comparing uses and gratifications for users. However, sex differences were not found for the most popular uses and gratifications, indicating that in general men and women meet the same needs by using the sites. As cited by Wong, F. M. , Lean, M. L. , Fernandez, P. R. (2011), Hirst (2009) mentioned that SNS usage among females is more social relationship-oriented while the use of SNS among male respondents is outcome-oriented. Pros and its Criticism The Uses and Gratification theory is concerned that how people use media for gratification of their needs. Choices of the media for the media users are increasing, this approach is to direct the media’s attention to the audience. The Uses and Gratification theory bring advantages and disadvantages to people in their daily life. Nowadays, media become more and more important in our daily life. Advantages of the Uses and gratifications theory is this theory is one of the communication model which is more positive views of the media. This is because this theory posits the users have complete control over what kind media that they want to use, how they use it and what the effects on them. The uses and gratification theory reminds the media that people are using media for many purposes. As media users become increasingly confronted with choices, this theory should direct media’s attention to the audience. (Suresh, 2003) Based on the Lull’s television research, found that families used television for communication facilitation, relationship building, intimacy and for structuring the day. (Suresh, 2003) The researchers have found out four kinds of gratifications. The first information, people want to know about what is happening in the society and the world to satisfy their curiosity. The second is personal identity, people willing to look for models for their behaviors. This can help people to decide what is the feeling about themselves and if the media view the same behaviors, that mean the media is also agree with their behaviors so they will feel successful and feel better about themselves. Next is integration and social interaction. People use the media to find out more about the circumstances of other people, by watching a show may help the people to empathize the lives of others. The last is as entertainment, people sometimes use media for relaxing, enjoyment or sometimes just to fill time. Uses and gratification is useful for studying the motives and usage pattern of computer game players. (Hou, 2011. ) This research framework assumes the majority of people choose the particular communications is to satisfy their needs and interests. Gamers that with different social backgrounds and demographic always had different expectations and uses of the same media. (Hou, 2011. ) The uses and gratification theory is well fitted for studying the interactive of playing game. It provides principle for the gamers to gain insight on the impact of game experiences, the role of players’ choices and actions and their usage pattern when playing game. The uses and gratification theory have some limitations. There are three major criticisms of the users and gratification theory. (Littlejohn, 1989, P. 276) The first argument is due to the lack of coherence and it is non-theoretical. Although a more unified vision is emerging, some uses and gratification researchers are developing a theory that connects this work with another kindred program on dependency theory. Based on the researcher, Blmber said that â€Å"The nature of the theory underlying uses and gratifications research is not totally clear. † (Katz, Blumler, and Gurevitch, 1974) There is confusion between gratification and satisfaction of people, whether people is only seek what they want or enjoy it. (Littlejohn, 2002) The second criticism is focusing on social and political objections. This problem is because the uses and gratification is so focuses on media functional role and ignores its dysfunctions in the society. People view media positively which can meet their needs, but they do not pay attention to the overall negative effects of media in the society. Many people criticised that the uses and gratification theory as they believed that the public actually do not control on the media and what it produces. Media do not need to take responsibility for what they produce because public is too kind to the media. Although there are many choices available for the users, they actually do not have the control over the media about what the media produces. The information that obtained by the users is solely prepared by gatekeepers and the information may already include the influences and perception of the gatekeepers. (Littlejohn, 2002) Last there is argument said that uses and gratification theory make media consumption behavioristic and individualistic. Uses and gratification theory has criticized as â€Å"vulgar gratification† which is highly individualistic nature. It only focused in the individual psychological gratification derived from individual media uses. Individuals are believed to control their media-consuming behavior according to conscious goals. (Littlejohn, 1989, P. 276) As mentioned above, people will not pay attention towards the ways to form media content and reflect the cultural values. Zillman, Denis McQuail showed one of the weaknesses of the uses and gratification theory is that the mood of people will affect their media choice. People choose what contexts to view or depend on their mood or feelings. For example, boredom encourages for choosing the exciting context, stress encourages the choice of relaxing context. Therefore, it is argue that the uses and gratification theory is often too individualistic, so it is too difficult to predict beyond the people. Some analysts have doubted the accuracy of self-reports on the uses and gratifications obtained from the media. They argue that such an approach is too simplistic, underestimate the complexity of human motivation. Self-reports are based on personal memory which can be problematic (Nagel et al. , 2004). This is because the respondents might not recall exactly how they behaved in media use which in turn distort accuracy of the study.

Design of a Standalone Energy System

Design of a Standalone Energy System Design of a Standalone Energy System and its Comparison with Grid Connected System in Pakistan Abstract During last few decades the investment and interest in the development of solar energy is being increased. PV is becoming more and more popular in those countries which can bear large investment cost and can offer economic incentives to the investors and almost in all those areas of world which are looking for a clean environment and working hard for green energy projects. This thesis work covers the design of a standalone power system and comparison of this designed system with already existing grid connected system in Pakpattan, Pakistan. After preliminary designing, an estimation of system and different components sizing was made and on the basis of this sizing, different energy sources like PV, wind and diesel generator were tested. Also if PV can fulfill the daily load or a backup diesel generator would be needed. For preliminary designing, Sandia sheets and PVSYST were used but for the actual designing, HOMER was used because HOMER is more accurate and precise tool for designin g standalone power systems. Simulations were carried out and the cost of energy per kWh was 0.435$. Total initial capital cost was 6517$. Further economic evaluation was carried out and was compared with already existing grid connected system. On pure economic terms, this system does not seem to be economical feasible but when different recommendations were taken into account like government subsidy and carbon credit then this system was economically feasible over the 25 years which is the life of this project. 1. Project background and Introduction 1.1 Introduction The project with respect to this thesis is to design a standalone energy system and to compare it with already existing grid connected system. This system might be PV alone system, PV wind hybrid system, PV Diesel hybrid system or just diesel generator system. This system is designed for a Jamia Masjid (Islamic center) in Pakpattan, Pakistan. The exact site of the project is a colony of Pakpattan which is in the south-west of the city Pakpattan. The Pakpattan city is situated around 161 Km south west to Lahore. The climate and weather data is almost same for Lahore and Pakpattan. Furthermore it will be first project of its own nature in this area and it will help to design the systems for the residential areas by which a common person can get benefits and get rid of power failures. â€Å"Pakistan is located between latitude 24 and 37 degrees North and longitude 62 and 75 degrees East. Pakistan has Afghanistan in the north-west, Iran on west boarder, India is on the east, China in the north and the Arabian Sea is on the south† [1]. Pakistan is ageographical centre of the Asian Continent because it builds a type of bridge between Far East and Middle East; also it has a continental type of climate which can be characterized by extreme variations of temperature. Generally the climate of Pakistan is arid, means very high temperature in summer and low temperatures in winter. High altitudes change the climate in the freezing northern mountains which are covered by heavy snow. There is little rainfall. There are some differences exist distinctly in various locations, e.g. the coastal line along Arabian Sea is usually under warm conditions, whereas the Karakoram mountain range and some other mountains of far north are so cold, completely frozen and covered with snow that these are only visible and accessible by some international world-class climbers for a couple of months of May and June of each year. The variation of daily temperature could be 11 0C to 17 0C but in winters the minimum mean temperature is about 4 0C in January. Pakistan has tremendous recourses of energy but unfortunately due to mismanagement out of 170 million population just 65-70% has access to electricity. Demand is more than supply of energy to residential and industrial sector. Currently Pakistan is facing 3000 MW of power storage and it is expected that in year 2010 the demand will exceed supply by 5500 MW. The current power and electricity demand and supply gap shows that there is a big need to increases the current power generation capacity in Pakistan. [1] 1.2 Aim of the thesis The main aim of the project is to design an independent and stand alone energy system for an Islamic center in Pakpattan, Pakistan. During the attempt to design this independent energy system, there could be sub aims as well, which are the procedures and details of the design are presented with step by step. There are main following aims which are supposed to be fulfilled by this thesis. * To go through the core knowledge of the designing process. * Obtaining data for the boundary conditions such as load, solar radiation wind data, available components, cost for fuel, electricity and components. * Sizing of the system. * Optimizing the cost. * To get familiar with different tools used for designing and make selection between them. * Beyond from bookish knowledge, get to know some real and practical aspects of different PV systems and projects. The body and structure of the thesis is mainly divided into four phases. * Introductory part (Abstract, contents) * Main part (Introduction, Background, Description, Analysis, Calculation of the primary load for this specific project. Boundary conditions and design parameters. Economical look on existed grid connected system and Comparative study between this newly design system and already existing grid connected system in terms of economics, Results and Conclusion ) * Reference part (Reference list and Appendices) 1.3 Method As the aim of this thesis project is to design an independent energy system for Islamic center and then compare it with existed grid connected system. The main interest is to provide electricity for Islamic center without shortfall. To do so, first of all literature survey was carried out and was gone through different designing procedures for standalone independent systems. Different tools were also tried and testified, so that an appropriate design could be chosen. In this way Scandia sheets, PVSYST and HOMER were considered especially because these tools were used previously to design such systems. First of all load demand was calculated. Why these three tools were used, the reason is that Scandia sheets are very helpful in sizing different components of standalone energy system while PVSYST has very big database of PV modules, batteries, inverters and diesel generators in itself. After that when the sizing was done then specific components were chosen for this stand alone system. In HOMER there are different options to check weather PV, PV wind hybrid or PV diesel hybrid system is feasible After designing the system, its economic analysis was carried out using different economic parameters like pay back periods, net present value, benefit to cost ratio and internal rate of return. 1.4 Energy profile of Pakistan The energy profile of Pakistan is inadequate and there are always short falls of energy (electricity) especially during summer. Pakistan needs around 14,000 to 15,000 MW electricity everyday to meet all residential and industrial demands. But Pakistan can produce around 11,500 MW, so it means there is around 3000 MW to 4000 MW short fall. The reasons for this deficiency are limited fossil fuel resources, weak economy and mismanagement of the available energy sources. In 1.1, an overview of primary energy supplies in Pakistan is presented in MTOE (TOE: ton of oil equivalent. It is an energy unit which is equal to the energy of burning of 1 ton of crude oil which is about 42 GJ) [2] From 1.1 it is clear that energy supply of Pakistan is highly dependent on Oil and Gas, both contribute more than 79% of total primary energy supplied. The other sources like hydro- electricity, coal, nuclear electricity and imported electricity contribute about 21% of the total share. Pakistan has been growing in agricultural and industrial sector during last decade and thats why energy demand is being increased. As population and industry is growing, the daily demand will increase up to 20,000 MW in 2010. Natural gas has played an important role to meet the energy needs in recent years. But Pakistan needs to expand its energy resource on permanent bases. In order to overcome this energy shortage, Pakistan needs to develop its indigenous energy resources such as hydropower, wind and solar energy. Pakistan is one of the highest solar insulation areas of the world. [3] Here are the main sources of energy in Pakistan right now; * Natural Gas * LPG * CNG * Oil * Coal * Nuclear Energy 1.5 Renewable energy sources in Pakistan Pakistan is situated in such a special geographic location that it is blessed with abundant and inexhaustible Renewable Energy (RE) resources. These resources can play an effective and considerable role for the contribution towards energy security of Pakistan. When we look into current world energy scenario in general and energy scenario of Pakistan in particular, the development and adoption of RE technologies makes better sense. Government policies and objectives to develop RE technology are also matching with this sense so that the share of RE in overall energy mix should be at least 5% by the year 2030. Solar energy has 2.9 Million MW potential and wind energy has around 0.346 Million MW while Mini Small Hydel has 2,000 MW. [4] There is a significant potential of wind energy in Pakistan especially in the coastal belt of Baluchistan and Sindh, and also in deserts of Sindh and Punjab. However this renewable energy source has not been utilized. â€Å"AEDB collected the wind data of all Pakistan from Pakistan Metrological Department and was analyzed. On the basis of this collected data and analysis, it was stated that the coastal belt of Pakistan has a God gifted 60 km wide (Gharo-Keti Bandar) and 180 km long (up to Hyderabad) wind corridor† [4]. This wind corridor has the potential to generate 50,000 MW of electricity. AEDB has done other different surveys in Gharo and Jhimpir regions and some coastal area of Baluchistan. After these surveys it is concluded that in the south region most of the remote villages can be easily electrified through micro wind turbines. Furthermore it is estimated that in Baluchistan Sindh and Northern areas more than 5000 villages can be electrified through wind energy. [4]. In 1.2a and 1.2b wind and solar maps for Pakistan are shown. Sincere efforts and aggressive lobbying has been done by AEDB with national and international investors to invest and to make them realize the tremendous potentials of RE. AEBD is in negotiations with international companies to set up their business in Pakistan. However large wind mills have not been installed yet but 30 wind mills for water pumping have been installed on experimental basis in different parts of Baluchistan and Sindh. In southern coastal areas of Pakistan remote villages are currently electrified with energy and so far more than 17 villages have been electrified using micro wind turbines. Around 95% of total electricity generation is from hydropower in Pakistan. But during hotter months of summer, it cannot meet the energy requirements due to less productive. Also 70% of population lives in around 50,000 villages. Many of these villages are very far from the main transmission lines and also it is not economically viable to connect these small villages to the main gri d due to their small population. On the other hand solar energy has excellent and significant potential. Pakistan is one of those countries which receive solar radiations at high level throughout the year. Every day it receives an average of about 19 MJ/m2 of solar energy. Studies have been already done and solar systems have been developed and tested. [4] 1.6 Potential of PV in Pakistan The location of Pakistan is very ideal to take advantage of solar energy as a source of energy because Pakistan is in the Sun Belt region. Solar energy is available abundantly and widely distributed all around the country. Following shows solar insolation map for Pakistan. The map shows around 200-250 W/m2 per day. The Baluchistan province is very rich in solar energy. It receives around 19-20 MJ/m2 per day averagely which is equal to 1.93-2.03 MWh/ m2 per day with annual 8-8.5 mean annual sunshine hours. These conditions are ideal for PV and solar energy applications. [5] Solar energy is very good option for off-grid villages. There are around 75,000 off-grid villages which contains 4 million homes and every home accommodates around 4-5 people. These off-grid villages are situated in the Baluchistan and Frontier Province. AEDB has set a target to electrify a thousand villages via solar technology by the year 2010. In this respect the first contract has been given to the Sehgal electronics group (Pakistan). Each home which is electrified with PV will have around 400W power supply and lead acid batteries for overnight storage. There are also other plans to have local production using PV modules with and estimation of this production is around 3MW/year. [6] 1.6.1 Possible routes for solar PV in Pakistan The global demand of PV equipment is increasing day by day and due to this fact the prices for PV systems, equipment and electricity has gone down remarkably. PV could be exploited in Pakistan through following two routes. [6] 1.6.1.1 Off-grid or stand-alone sector Stand-alone or off grid systems generate electricity independently of the utility grid. Stand alone systems can be a very good option for the remote areas and very deep located villages, where the extension of power transmission lines would be more costly. Also it could be implemented in environmentally sensitive areas as parks, remote homes and cabins. In rural areas, it could be used for solar water pumps and farm lighting. [6] 1.6.1.2 Grid-connected sector Grid-connected PV systems supply extra power when the home systems power supply is not sufficient to fulfill the load. These systems remove the need of battery bank. In some situation, utilities allow net metering, by which the owner can sell extra power back to the utility. [6] 1.6.2 Current solar energy applications in Pakistan Both PV and solar thermal have a wide range of applications in Pakistan. Although the scale of utilization and adoption has been very small but it has been utilized for last 25 years in Pakistan. Different applications mainly PV and solar thermal applications are summarized as. [5] 1.6.2.1 Photovoltaics Eighteen PV stations were built by the government in the early 1980s to electrify different villages the country. The installed capacity was nearly 440 kW but due to the lack of technical knowledge and follow up, these systems could not perform as required. Currently in Pakistan solar energy is being used for telephone exchanges stand alone rural electrification, cathodic protection, highway emergency telephones and vaccine refrigeration in hospitals. In different parts of Baluchistan, about 20 solar water pumps have been installed for drinking purposes by The Public Health Department. The northern and western area of Pakistan are mostly hilly and mountain areas (Hindu Kush-Himalayas, HKH region), which are blessed with a lot of sunshine with 4-6 kWh/m2 daily average solar radiation. Seven solar stations were installed in this region in the late 1980s for lighting by different companies. The total capacity of these systems was 234 kW. They are not in operation now due maintenance pro blems. SIEMENS Pakistan has installed many stand alone solar systems in Pakistan. On the Lahore-Islamabad Motorway, it has installed power supply systems for many microwave-link repeater stations and more than 350 emergency call boxes. [5] 1.6.2.2 Solar thermal applications There are many applications which utilize the heat characteristics of solar energy directly. These applications are very simple, low price and easily to adoptable. These include heating and cooling of residential and commercial buildings, cooking, water heating for domestic and industrial use and drying agricultural products. A brief description of such applications in Pakistan is given here. [5] 1.6.2.3 Solar water heaters This technology is quite mature in Pakistan but very limited because of its higher capital cost as compared to conventional water heaters which operate on natural gas. But in last couple of years it has started to gain popularity because a number of public sector organizations are working to develop low cost solar water heaters. The prices of natural gas and electricity are increasing day by day, so people are adopting solar water heaters and also private sector has already started the production of such heaters. [5] 1.6.2.4 Solar cooker Different public sector organizations have been working to develop low cost and efficient design solar cookers. In HKH region of Pakistan, more than 2000 solar cookers are in use. This number is very small. It needs to be more popularized. Pakistan needs to reduce the use of precious forest resources as fuel wood and to replace it with solar cookers. [5] 1.6.2.5 Solar dryers Solar energy can be very good option for drying agriculture products. By this, we can get very good quality products at much less cost. Northern mountainous areas like Gilgit and Sakardu are very rich in fruit production like apricots which used to be wasted by tons every year. But now solar dryers are being used to dry large quantities of fruit, which is leaving a positive effect on the economy of this area. Different NGOs are working for the popularizing and the use of such dryers. [5] 1.6.2.6 Solar desalination Drinkable water is unavailable in many parts of Sindh, Baluchistan and southern Punjab and it is very critical issue. Underground water is available but it is highly saline. This saline water is not fit for drinking at all and causes many dangerous diseases such as hypertension. Solar energy can be utilized to convert this available saline water into drinkable water. Solar desalination is very simple, low cost and easy to use. Also it is very easy to adopt. A successful solar desalination project is in operation and it is working very fine and helping to change the life style of the population of Gawader in the Baluchistan province. It consists of 240 stills and each can clean 6000 gallons of seawater per day. [5] 2. Types of PV and PV Hybrid systems Generally the classification of PV systems is based on their operational and functional requirements, the configuration of their components and the connectivity of the equipment to power sources and electrical loads. PV systems are designed to supply DC and/or AC power and can operate interconnected with utility grid or independent of it. There are classified as;  · Grid-connected Photovoltaic systems  · Stand alone Photovoltaic systems 2.1 Grid-connected PV systems Grid-connected PV systems are designed to operate parallel with the interconnection of electric utility grid. Power conditioning unit (PCU) or inverter is very basic component in grid-connected PV systems. PV array produces DC power supply and the PCU converts it in to AC power supply which is consistent with the power and voltage requirements of the utility grid. PCU automatically stops the power supply to the grid when utility grid is not energized. [7] 2.2 Stand alone PV systems Stand alone PV systems or off grid systems are designed to operate independently. Mainly stand alone PV systems are used in isolated and remote areas where the connection with grid or electricity network is not possible. In this type of systems the storage system (batter bank) is very important component and storage is guaranteed by batteries. The design and sizing of such system should be done in a way that it could supply and meet the required load even in bad weather conditions or during winter months. For this surety these systems could be coupled with diesel generator, wind turbine or hydro generator and the systems after this type of coupling is called PV Hybrid systems. There could be different arrangements and designing methods of PV systems depending on the requirements and type of load to be fulfilled. In direct coupled system, DC power is supplied directly from PV array to DC load and there is no energy storage, thats why this type of systems can operate in sunlight hours which make them suitable for common applications like water pumps, ventilation fans and small circulation pumps used in solar thermal heating systems. In many other type of PV stand alone systems battery bank is used for the storage of energy and power inverters which can fulfill AC/DC loads at the same time. [7] 2.3 PV Hybrid systems PV hybrid systems are composed of combined solar energy with some other electricity producing sources like wind turbines, diesel generators or small hydro plants. The choice of other source of energy to be combined depends on the needs and the geographic situation and other specifications. The hybrid systems are best for the remote areas like islands and remote villages, also for remote applications like communication stations and military installations. Before go for designing a hybrid system, the specific energy needs and the available energy sources should be known. It means the potential for all available energy sources like solar energy, wind energy and hydro energy must be studied, so that the best combination could be made which can meet the specific energy requirements in best way of economy and availability. [8] 2.4 PV Diesel hybrid systems In remote areas the electricity has been produced by engine driven generators in the past. For those applications where we need a reliable and stationary generator is required, diesel generators are preferred. Petrol generators may provide electricity at lower cost due to their less frequent use. Engine driven generators are less efficient when driven at light loads (around 40 to 50% of their rated capacity) which can shorten their operating life and it results in high maintenance cost. When the engine is operated at light loads, the combustion temperature goes down which results incomplete combustion and carbon starts to deposit (glazing) on cylinder walls and this leads to premature engine wear and tear. In recent years, the cost of renewable energy technology has been declined continuously and also the concept of usage of alternative energy is growing day by day. Due to these two factors, the utilization of renewable energy has been increased for remote areas. Typically PV modules with small to medium size wind turbine are being used, but for some locations small hydro electric generators are suitable. In simple words combination of renewable energy sources and conventional energy sources with energy storage (battery bank) makes a Hybrid system which can give reliable and economic electricity supply. If we compare a system only with PV generator with a PV hybrid system, the second one reduces the batter size and improves the reliability of overall power supply. In hybrid system, the renewable energy source and battery bank try to reduce the run time of diesel generator. There is sufficient storage in these systems which allow the load to be shifted. Generally these type of systems a re installed in those locations where the logistics and costs of a reliable supply of fuel are not major contributing factors to overall system operation cost. [9] The displacement type systems are sized to decrease the fuel consumption of diesel generator by 70 to 90% as compared with a diesel battery system, so it relies mainly on renewable energy sources like solar. The engine driven generator still remains in the system to equalize the battery and it provides a backup for those periods when there is low solar input or high load demand. Such systems are installed in those locations where some attractive incentives for the use of renewable energy exist or fuel supplies are costly and unreliable. [9] Usually the conventional power supplies with diesel in remote areas are not flexible to react to the changes in load demand and varying operating conditions. This results in the compromises on reliability and efficiency. Significant changes in long term and short term load demand could happen as a result of * Increase or decrease of population; * Special community events; * Seasonal change in environmental conditions ( summer, humidity); * Change of consumer trends (increased use of home appliances) But renewable energy sources and batteries are modular in nature and can be upgraded without any problem when in future the load demand is increased with time. It means that we do not need to change the whole system. But as far as other components of the systems are concerned, they are different in their nature. For example inverters, battery chargers and PV charge controllers should be in such a way that the future increased demand should not exceed their rated capacity. Power conditioning devices are also inherently modular and they facilitate convenient system upgrade. [9] 2.5 Hybrid System configurations PV-Diesel hybrid systems produce AC power supply by the combination of PV array with inverter, which can be operated parallel or alternatively with engine driven generator. PV diesel hybrid systems can be classified as  · Series hybrid energy systems  · Switched energy systems  · Parallel energy systems 2.5.1 Series hybrid energy systems In this configuration, the power generated by generator is rectified first and then converted back to AC supply to fulfill AC demand which incurs much conversion looses. During low electricity demand periods, the diesel generator is powered off and the demand can be fulfilled from PV and stored energy. AC supply reaching to the load is converted from DC by an inverter. In series configuration the system efficiency is low because most systems pass large fraction of produced energy from battery bank which increases the cycling of the battery. [9] The SOC (state of charge) of the battery and actual load decide whether the diesel generator will operate or not, which depends on power supply from PV and diesel generator, load demand and the batteries are either charged or discharged. Solar controller is used to control such situations which prevent the overcharging of the batteries, when PV supply is more than the load and also the batteries are fully charged. The gain in energy is marginal for a good sized system but we can add a maximum tracking point which can improve the utilization of available PV energy. The system can be operated either in manual or automatic mode. This can be done by adding some extra components in the system. [9] There are certain merits and demerits of these configurations, they are as below. Merits * It has simplified electrical output interface as no switching of AC supply is required between different energy sources. * The supplied power to the load is not interrupted when diesel generator starts. * The inverter can produce a square wave, modified square wave or a sine wave depending on application. Demerits * The cycling of the battery bank increases which decreases the life time. * As diesel cannot supply power directly to the load, thats why system efficiency is low. * If there is some problem in inverter or in case of its failure, it results in complete loss of power. In this case diesel generator has to supply power directly for emergency purposes. * The cycling profile requires the large battery bank to limit the depth of discharge. 2.5.2 Switched configurations It is one of the most common configurations used, but it has some operational limitations. As the name shows, it operates either with diesel generator or inverter as AC source but no parallel operation of the main power generation source is possible. Switched configuration hybrid systems can be operated in manual mode but it makes the system more complex. In order to get rid of this complexity, it is desirable to add some automatic control unit. â€Å"This automatic control unit can work by adding appropriate battery voltage sensor and start/stop control unit of diesel generator† [9]. The advantage of this configuration is that the load can be fulfilled directly from diesel generator, which gives overall higher conversion efficiency. In this configuration both PV array and diesel generator can charge the battery. [9] This configuration has also certain advantages and disadvantages as Advantages * As the generator can fulfill the load directly, it improves the efficiency and reduces the fuel consumption. * The inverter can make a square wave, modified square wave or a sine wave depending on application. Disadvantages * Power supply is interrupted time by time as AC power sources are transferred. 2.5.3 Parallel configuration In this type of system PV and diesel generator supply the load separately when the load demand is low or medium. But when the load demand reaches at peck point, then PV and diesel generator combine and supply that peak load. In this configuration we use a Bi-directional inverter which has two functions * It can charge battery bank when excess energy is available from diesel generator (rectifier operation). * DC/AC converter (inverter operation). The bi directional inverter can also provide â€Å"peak shaving† which is defined as â€Å"the ability of parallel hybrid energy systems to supply load that exceed the power rating of the engine driven generator of the inverter from combine sources as part of the control strategy when the engine driven generator is overloaded †[19] Parallel configuration hybrid systems have also merits and demerits over other systems, like Merits * The efficiency of diesel generator could be maximized. * The maintenance of diesel generator could be minimized. * The system load could be fulfilled by optional ways. Demerits * It should be controlled by automatic control unit in order to make the operation of the system more reliable. * Operation of the system is much complex for untrained users 2.6 Power conditioning In PV diesel hybrid energy systems three types of conversion devices are used to control and conditioning of power flow. They are battery charge regulator, inverter and a rectifier. The rectifier or battery charger is included in the system to convert AC power generated by diesel generator to DC voltage. This is done to recharge the battery bank. Series type hybrid systems have always low efficiency because they use two conversions AC/DC and DC/AC. If we assume that both efficiencies of rectification and subsequent inversion of DC voltage are very high, lets say 90%, it will result a loss of 19% of total power gained in these conversions. This is the reason why parallel and switched cond systems have always more overall system efficiency. In hybrid energy system operation, usually the generator operates at 80% of its rated capacity. In switched or parallel cond energy systems AC power is supplied directly from diesel generator but the excess power which is more than the required load is used to recharge battery bank. This supply of power to battery bank is according to a defined battery charge strategy which takes the battery to high state of charge. In some modern parallel hybrid systems, a bi directional inverter unit is used. This bi directional inverter unit consists of solar controller, i

In The Heart Of The Sea |Book Analysis

In The Heart Of The Sea |Book Analysis In the early nineteenth century it was very common for communities to rely upon specialized products as a source of income. This book, In the Heart of the Sea: The Tragedy of the Whaleship Essex, is a story of a whaleship that was attacked by a giant bull sperm whale in the heart, or middle of the Pacific Ocean while on a voyage to acquire whale oil, Nantuckets prime commodity. The author, Nathanial Philbrick, describes the effects that this tragedy had on the city of Nantucket, the hardships that came along with being a sailor in the whaling industry, and the gruesome battle for survival that it placed upon the crew of the Essex. The early 1800s was a great and prosperous time for Nantucket. This community was extremely functional in the fact that it had a flourishing economy, little to no crime due to the harmony of the people and dominant Quaker religion, and well played roles of both men and women. As mentioned before, Nantucket heavily relied on whale oil as a source of revenue. At this time the price of whale oil was rapidly rising, thus stimulating their economy. Though it seems as if this town had it made, the act of obtaining whale oil was quite dangerous and often deadly. It was typical for men to be gone for years at a time out at sea and for women to lose their husbands and other male loved ones to the risky whaling business. Women as well had a very crucial role in keeping the town running smoothly. In addition to having to attend to normal everyday tasks of taking care of the children and household duties, they had to run a majority of the islands businesses. The women struggled with these tasks and because of the loneliness brought on by the absence of their spouses many began to fall in to the addictive traps of opium. It was tough to say the least but this was all necessary for the existence of this town. The Essex was a whaling ship used by the town of Nantucket in the nineteenth century. It, along with two companion ships, set sail in August 1819 from Nantucket Island in search of the one thing that was vital to the community, whales. Within the first few days of being out at sea the Essex experienced a great storm that almost killed everyone on board. Not only was the ship almost flipped over but the sails that they used to guide the ship across the ocean were torn. One of their three ships was swept out to see, leaving them with only two. Having no other choice the crew made stops along the coast of South America to restock the ship with various supplies and equipment necessary for the voyage. After embarking once again the crew eventually came upon two whales, which they killed. This was about half of the amount that the crew had set out to capture before returning back to Nantucket. Around mid-November 1820, nearly fifteen months after they had originally set sail, the crew came upon a group of whales needed to complete their journey. While trying to kill the whales, a giant sperm whale severely damaged the side of the ship making it unable to be fixed. It was at this point in which their nightmare started to begin. They were forced to abandon the Essex and take shelter on a nearby island. The crew brought a majority of their supplies with them because they feared that the rumors they had heard might in fact be true. It was said that there were cannibals on a close island towards the west. Capitan Pollard along with the other men decided to sail back to South America on their one and only ship. It ended up being over a month until they reached any land. Eventually they ended up at Henderson Island where they discovered that there was not a plentiful amount of anything, including fresh drinking water. Pollard decided to get back on the ship leaving three men behind who we hoping that they would eventually come back to help them. It wasnt long before the cre w on the ship started to become starved and dehydrated. After months of malnourishment they started dying off just one after another. At first they would throw their bodies overboard and bury them at sea but it came to a point in which they began to run extremely low on supplies. What the ironic part is about this story is that the men were faced with the tough choice of becoming cannibals and feasting off of their old crew members deceased body, giving them some hope for survival, or hoping for the best and reaching land soon. It is ironic in the sense that they were tremendously frightened by the tales that there were cannibals in close proximity to them, which is why they ended up not staying, but cannibalism actually ended up saving some of their lives. Only a few crew members from the original twenty survived, they included Thomas Nickerson, Owen Chase, Charles Ramsdell, Benjamin Lawrence, and Capital George Pollard. The tragedy of the Essex will greatly affect the community of Nantucket because they rely so heavily upon the whale oil for survival. When the Essex sank so did the whale oil, leaving the town with nothing recovered from that journey. Not only does it affect them economically it affects them socially as well. Many men lost their lives during this expedition, leaving numerous wives without husbands and children without fathers. As for the sailors who actually survived the harsh time out at sea it was hard on them after their return. Gossip went around the town talking about how the men became cannibals. The community was respectful towards the sailors though, they kept quiet about the topic for the most part. But, townspeople continued to whisper about the Essex well into the twentieth century, it was not a topic a Nantucketer openly discussed (Philbrick 217). The disaster made it extremely difficult to survive in this community, and eventually led to the collapse of it. This led to t he falling down of the whaling industry in Nantucket. The industry moved to other various locations along the New England coast, usually with deeper ports than that of Nantucket. Shortly after this a major catastrophe happened to the town of Nantucket. Fire raged across the town leaving many homeless, jobless, and with nothing. Philbrick describes the event saying à ¢Ã¢â€š ¬Ã‚ ¦more than a third of the town and almost all the commercial district was charred wasteland (222). After this accident many people took off to the west to California to start a new and having hopes of finding gold, leaving the town nearly empty. You would think that an event as serious that this would have a big negative effect on the nation no matter how small the incident, but it didnt at all. By looking at the time period in which this took place, other issues that were a concern of America, and the sheer size of the nation you can tell why it had such a minor effect on the country and received almost no attention or interest. Whaling was not a concern of the entire nation because it only benefitted a certain region. Also, we were getting over wars that had been going on for awhile. When looking back at the series of events that took place over this entire story you can start to see where crucial errors in decision making in which determined the fate of the voyage. As I had mentioned earlier the Essex went through a major storm that tore up the sails and made the ship nearly inoperable. Capitan Pollard, with his years of experience in commanding ships, suggested that the crew turn the ships around and head back for repairs so that they could travel more safely down the road ahead. Two of his less experienced mates disputed that there were extra ships available at a close port, and that they should just keep moving along so that they would not waste time. Philbrick writes that, Pollards behavior, after both the knockdown and the whale attack, indicated that he lacked the resolve to overrule his two younger and less experienced officers (101).

Hitler :: essays research papers

Adolph Hitler was responsible for World War II and the massacre of millions whom he thought to be inferior. He was also one of the most powerful and influential leaders of the 20th Century. Hitler single handedly built up his Nazi party into a massive power, which would eventually control most of Europe and North Africa. How is it, that a man of such evil had so much influence and control? We would like to think that never again will such tragedy occur. Never, would we let such a man into power. Yet, it happened in the 1930’s, only 70 years ago. What factors resulted in Hitler rising to power? Rather than one single reason, it was the perfect combination of luck and leadership, at just the right time.   Ã‚  Ã‚  Ã‚  Ã‚  In Austria, 1889, Klara and Alois became the proud parents of a baby boy – Adolph. As a young boy, he attended elementary school at the Benedictine monastery at Lambach. His early school years went well. Adolph earned good grades, became a choirboy, and anticipated one day becoming a Catholic priest. As he got older, he began getting into serious quarrels with his father. This fighting, he later claimed, caused his marks to slip. By the age of sixteen, he had quit school.   Ã‚  Ã‚  Ã‚  Ã‚  Once out of school, Adolph refused to find work or learn a trade. Rather, he spent his time going to the Opera, and reading. For hours on end, he would read books on German history and mythology. As a result of the reading, he soon found himself very concerned with the world’s tribulations. A school friend later recalled: â€Å"Hitler was always up against something and at odds with the world. I never saw him taking anything lightly.†   Ã‚  Ã‚  Ã‚  Ã‚  At the eager age of eighteen, Hitler had a new dream. He wanted to become an artist, as this was now his one true passion. The Vienna Academy of Fine Arts quickly turned him down after his entrance examination. This rejection would hurt him for his remaining life.   Ã‚  Ã‚  Ã‚  Ã‚  Another devastating event followed shortly after; the death of his beloved mother only four days prior to Christmas. Hitler later wrote: â€Å"It was a dreadful blow. I had honored my father, but my mother I had loved. Her death put a sudden end to all my high-flown plans. Poverty and hard reality compelled me to take a quick decision. I was faced with the problem of somehow making my own living.

Marhsal Field :: essays research papers fc

Marshal Field The elder Marshall Field considered himself the â€Å"Chief Apostle of the American Way,† he epitomized the American Dream by becoming one of America’s first rags to riches stories in the industrial boom of both the pre-Antebellum and post-Antebellum periods. Marshall Field was born and raised as a humble farm boy and became perhaps the greatest businessman this country has ever had. Field learned his work ethic as a young boy by direct example of his father, who started working two hours before daybreak and stopped two hours after. As soon as Marshall could walk, he was working on the family farm. At the age of six, he enrolled in district school only during the winter months when farm work was scarce. He continued these lines of life until the age of fifteen, when the Field family was forced to stop working their farm due to a road closure. At this time it was decided that since Marshall was the youngest son and did not qualify for of the estate property, that he would have to go out and earn his own living. His father being friends with the local dry goods (general store) owner secured Marshall a clerking job in the dry goods store. Ironically, Marshall was fired from that same job after two weeks. When the father inquired what had happened the owner told him that your son has no future in the dry goods market and he should be kept at home on the farm where he belongs. Marshall Field then began working as a hired hand on his brother’s farm. After two years of being his brother’s servant, he moved to Pittsfield, Massachusetts with his other brother. His brother had secured Marshall a job at the Deacon-H.G. Davis dry goods store. There his first year salary was a measly $400. However, he was able to save two hundred of this by sleeping in the store. By the time of the 1857 panic, Marshall had modernized Deacon’s credit policies; subsequently Deacon was not monetarily damaged by the panic. By modernizing Deacon’s credit programs Field was able to insure the store’s future by making credit harder to attain, by shortening the amount of time customers had to repay the store. Because of some unwise business dealings the store’s owners had been involved in, the store was reorganized into Cooley, Farwell and Company. Marshall Field was then awarded a partnership for his part in saving the store from the Panic.

Pop Culture Archetype Comparison

The archetype of the villain is seen in many Disney fairytales and are usually one of the most important characters in the films. Shan Yu from Mulan and Scar from The Lion King although are from different backgrounds and different plots both display the same characteristics and thought processes. SIMILARITY 1-The primary similarity between Shan Yu and Scar is that they both will stop at nothing in order to conquer the land and power that they think they deserve. This is seen in Mulan, where Shan-Yu feels no hesitation when it comes to taking a life. He kills without remorse, for his own amusement. This is demonstrated when he asks â€Å"How many men does it take to deliver a message? † to which one of his henchmen replies â€Å"one† as he aims his arrow at one of two Chinese spies. This is also seen in The Lion King. Scar the evil brother of Mufasa will do anything to become King of the Pride Lands, even if it means killing his brother and his nephew Simba. Although he only succeeds in murdering Mufasa, he convinces his nephew that it was his fault, leaving Simba to live with the guilt of his father’s death and tells the cub to ‘run far away, Simba, and never come back’. SIMILARITY 2-The second similarity between Shan Yu and Scar is their similar deaths, in which the hero takes part in taking down the villain. Shan Yu gets thrown off a building by Mulan and Scar is pushed off a cliff by Simba. CONCLUSION- Therefore both characters are seen as the classic archetype villain and have many similarities such as their lust for superiority and power. However, while both characters have many similarities between them they also demonstrate some differences as well. DIFFERENCE 1- A major difference between the two characters is that Shan Yu is a Mongolian leader of the huns whereas Scar is a lion from Africa. Although Scar is not a human being, the character still demonstrates the same desire to conquer the land. DIFFERENCE 2- The second difference between Shan Yu and Scar is the means in which Scar grew up, for example growing up Scar’s father spent more time and attention on his other son Mufasa. This ultimately leads to Scar hating his brother and constantly seeking revenge against him. While, for Shan Yu, growing up because of his cultural and political background he has always hated the Chinese and wanted to take them down. However, the two characters both attempt to conquer and take down their opposing forces whether it is their family or political enemies. Relevance- The significance of the archetype of the villain in both films is that they essentially help the main character, the hero to complete a quest or journey of finding who they really are. In Mulan, if it were not because of Shan Yu and the threat of the war, then she would have never had to change her lifestyle or leave her family behind. This would not have made her the person she became towards the end of the film. The same goes for Simba, if it were not for Scar telling him his father had died and there was nothing left for him there, furthermore he was able to see how others lived and decide that he wanted to rule. Conclusion- In conclusion, while both characters are archetypes of the classic villain. They both demonstrate the same ideals and desires to be achieve total control and superiority over the people around them.

British Citizenship Under Neoliberalism

Neoliberalism simplifies trade between nations. It involves uncontrolled exchange and movement of goods, services, resources and activities with the aim of acquiring profit leverage with efficiency through cheap resources (Shah, 2007). Neoliberalism espouses the removal of the free trade barriers. These barriers include tariffs, regulations, laws and legislation, and investment restrictions. Neoliberalism is the intensification and expansion of the market through the increase in quantity, frequency, recurrence and formalization of transactions (Treanor). The goal of Neoliberalism is to enhance market competition in every transaction process.These transactions tend to be more competitive if they occur repeatedly for short periods of time. This way the dynamism of the cycle of cost and profit remains active. The basic principles of Neoliberalism include the freedom of trade in goods and services, limitless circulation of capital and, investment capacity and opportunities. The concept o f Neoliberalism involves several vital points mainly in reference to the economy. The five points include the rule of the market, reducing public expenditure for social services, privatization, deregulation, and the concept of individual responsibility against public good (Martinez & Garcia, 2000).The rule of the market means limitless freedom of the flow and exchange of goods, services and capital. It sustains that the market regulates and balances itself through the dynamics of market demand. The government has a hands-free policy when it comes to the dealings of the private enterprises like the freedom to determine prices of commodities. International trade and investment are likewise encouraged. The next point is the reduction of public expenditure for social services. Social Services comprise health, education and infrastructure development among others.Privatization is a main aspect of Neoliberalism in that it espouses the transfer of the previously state-owned enterprises or businesses like banks, schools and hospitals to private investors. There are two opposing views on privatization. On one hand, it increases efficiency of the enterprise under the ownership of a specialized private group. On the other hand, privatization results to a concentration of wealth and power to a few groups. Deregulation is another aspect of Neoliberalism. It refers to a reduction in the regulating power of the government. Instead, the market is allowed to regulate itself with the aim of maximizing profits.The last point is the concept of individual responsibility versus public good. Each individual is responsible for his or her conditions in life. The decrease in government support to the community for education, health care and social security should be compensated by the individuals themselves. What are the justifications of Neoliberalism? Is it an underlying theory for most of the economic successes of a nation? Neoliberalism promotes the idea of a free market without go vernment interventions in order for resources to be more efficiently distributed to groups in society who can better handle businesses.It likewise supports the idea that privatization of enterprises takes away the inefficiency or incompetency of the public sector in running businesses. Neoliberalism believes that the best way to achieve progress is through continued economic growth and the inevitable road to success is economic globalization. Economic globalization pertains to trade and financial movement as the factors which increase the integration of world economies (IMF Staff, 2000). It is also referred to as the transfer and exchange of knowledge and labor beyond the national boundaries and into the international field.The term Globalization is most often interchangeably used with Neoliberalism because of the similar principles that both concept advocates. Both support free trade as the ultimate means to achieve economic growth. Globalization leans more towards the weakening of national borders and the increase in the assimilation of global policies and trends in the national level. The aspects of Globalization include trade, movement of capital, movement of people and information dissemination and exchange through technology.Information exchange has been significantly globalized due to the proliferation of the internet. The global financial market run on a very fast pace due to the internet where transaction can be done with just one click. Movement of capital involves foreign investment and movement of people refers to employment opportunities outside the home country. These employment opportunities give way to an increasing trend of migration from developing countries to countries with more advanced economies.On the other hand, Neoliberalism is more focused on the nationwide aspect of trade with major effects from the international trade community. Other policies supported by Neoliberalism include the maintenance of competitive exchange rates where mar ket-determined exchange rates are followed instead of government-fixed exchange rates (Neoliberalism). Another policy is fiscal rectitude where expenditures are reduced and taxes are increased to sustain a budget surplus. II. The Neoliberal Revolution in Great BritainPrior to the Neoliberal Revolution, the dominant principle in both Western and most parts of the Third World economies is the Keynesian concept (Ambrose). John Meynard Keynes was an advocate of the idea that government interventions are needed to lead markets in endeavors which would benefit the most number of people. This idea was put to a halt when Neoliberalism began to take shape. In 1975, Margaret Thatcher became opposition Conservative Party head and was elected as Prime Minister in 1979 (Scott, 1997).She was determined to alleviate the condition of the British people from recession to economic greatness. The Neoliberal Revolution started in 1980 with Margaret Thatcher as the main proponent. The proposal of the re volution included decrease in corporate taxes, corporate regulation reduction, public services privatization and abolition of international trade barriers (Moore, 1998). At this time, privatization was a major practice and the primary force of Neoliberalism, as power, assets, rights and responsibilities along with a great deal of autonomy were afforded to private enterprises.Thatcher’s principle of Neoliberalism was supported by her TINA or There Is No Alternative campaign (George, 1999). The significance of Thatcher’s neoliberal policy lies in the idea of competition as an essential part of growth. Nations, regions, companies and individuals compete with each other. This competition makes the market more effective as it maintains only those who survive or those who won against the others. Thus, only the best resources, may it be natural, human, physical or financial, are included in the final market competition.It is the belief of Thatcher that people by nature are un equal so there are no worries about issues of social inequality as a hindrance to economic success. Those who are the strongest, more intelligent and well-educated can contribute best to the welfare of the country and its people. On the other side of the fence, the weak and the poorly educated are only responsible for themselves and have themselves to blame for their status. The Neoliberal Revolution introduced changes in policies which brought about the negative effects to the public sector.The budget for the health sector was reduced which meant less free health services for the people and the privatization of health services was started resulting to the charging of fees and introduction of insurance policies (Navarro, 2006). A very important factor in the Neoliberal Revolution is not only the promotion by the U. K. and U. S. governments, but the support it got from international organizations like the International Monetary Fund (IMF), the World Trade Organization (WTO), the Worl d Bank and the World Health Organization (WHO).III. Effects of Neoliberalism on British Citizenship The main goal of citizenship is equality among the people. There are three forms of citizenship: civil, political and social citizenship. Civil Citizenship comprises employment, private property and contract protection, and market access. Political Citizenship involve the right to vote and hold public office, while Social Citizenship means the right to the provision of education, health benefits and other social services (Sparke).The rights of the citizens are mainly dependent on the policies of the government. Neoliberalism had a great impact on the government policies in that citizenship was largely affected to its detriment. It is important to note the social policy of Neoliberalism before we move further into a discourse of its negative effects on citizenship. In Neoliberalism, social policy means the provision of equal opportunities available in the market and equal legal treatme nt to all citizens (Rosch). This is also the measure of social justice.The social policy does not include concern for the social welfare of the people. Its premise lies in individual responsibility where each person is responsible for achieving his or her own social and ethical ideals. This responsibility is not to be shouldered by the government in any way. This social policy is deemed as leaning favorably to those with financial power and is discriminating and pushing those at the lower level of the economic ladder further down. Neoliberalism threw its strongest punch on the social form of citizenship.Social services were privatized and budget cutbacks were enforced as part of the fiscal rectitude policy where expenditures are reduced to maintain a budget surplus. Education, health services, housing, transportation and other social services were stripped off their importance as part of the government’s responsibility to its citizens. Instead, the people are encouraged to st rive on their own to meet these needs. The social services organizations were handed over to private institutions which now are to be dealt with if the people need the kinds of services they offer.Since these private enterprises are now competing in an open market, the cost of availing their services becomes expensive and incomparable to the previous benefit that the citizens were receiving from the government. The negative impact is most felt by the underprivileged and advantage is savored by the wealthy and powerful. Civil Citizenship was likewise adversely affected by Neoliberalism in terms of the contract and employment terms. The most notable effect is the reduction, if not elimination of the trade unions which are primarily based in public enterprises.Privatization meant abolishing of the existing systems as the policy making is transferred to the owners of the private companies. Protection of the employee was abandoned with the increasing short term contracts along with short duration of jobs. Employees now are offered shorter tenures which force them to undergo the tedious task of re-applying to companies. With private companies’ anti-union policies, the employees now have nowhere to go. They either sink or swim. Employment opportunities are now available to more competent and well educated individuals.The name of the game became employability or the capacity of the individual to sell his or her services based on the acquired knowledge and skills. This now brings us back to the issue of the advantage of the more financially able citizens. Individuals with access to good education from schools which are now private enterprises and which are now able to charge high fees, has the advantage. The flow of trade money between enterprises, regions and even between nations on a wider scale as espoused by neoliberalism, has a tremendous effect on the electoral system or the political aspect of citizenship.The exercise of electoral right is now deemed futi le as doubts are cast upon the veracity of the election results because of the money generated inside the politics arena. Politics, as a powerful venue of pushing legislative programs or business leverage, is considered to be a channel used by some groups or enterprises in advancing their own personal agenda. Neoliberalism has in great part affected the entire nation including the people and how they function in society. Its effects are criticized left and right by different groups as to its advantages and disadvantages.Critics and proponents both have their valid points. It has to be stressed though that for a concept or idea to be considered truly successful is to analyze if a great majority of the people has benefited from the underlying principles of the concept. The ultimate question now is: Has Neoliberalism created a healthy balance between the rich and the poor or has it been an instrument to push the rich to the topmost part of the economic ladder and to push the poor furth er down the pit?
