Conceptual Definition of Family

Ingredients for a Family Family is a group of people who can love another person beside himself or herself, give and gain trust, and accept each other for who they are. When people love one another, they’re not concerned about themselves. Being selfless allows more room for love. In a family, members are able to compromise with the ones they love, in order to make the relationship work. Without trust, a family cannot confide in one another. Trusting the members of within the family shows the respect that they have for each other.Respect and trust unite families, giving them a sense of understanding for one another. Being accepted by the family makes people feel assured that they are loved. Diversity in a family also is a part of acceptance, which makes them feel more comfortable. Diversity may also cause conflict, not only in a family but also in social situations. There are many different qualities that make up a family. Love isn’t just an emotion; it’s a feelin g and a sense of comfort. Being surrounded by a family that loves one another is one of the best feelings in the world.Love is the one of the most important qualities a family must have. If there were no love in the family, no one would get along or want to be near each other. In the painting Freedom from Want, by Normal Rockwell, you can see the love between the family through the picture. Everyone is smiling and excited to be around each other (Rockwell 23). You can tell that they love being around everyone because they keep a smile on their faces, which shows happiness. Being loved and loving someone else are two different concepts. Being able to love someone other than oneself takes time and effort.The more time spent between families, the move love begins to grow. I consider love being like a tree. As the tree grows it becomes stronger and larger. The same analogy goes for love between families. As the family grows together, the love between the members gets stronger. Selflessn ess in a family helps the family grow stronger as a whole. It’s nice to care about yourself once in a while but when someone is a part of a family they should care about everyone. Taking care of a family sometimes challenges the members in it.At times you have to give up certain things that may be important to you for another member of the family. There are times in my family when one of us has to sacrifice going out or canceling plans for another member in my family. When my parents want to go out, I have to cancel plans with my friends to watch my sister, but I don’t mind because I know that they sacrifice plans for me all the time. That’s just apart of being selfless. An Indian Story shows a good example of selflessness. Roger Jack states, â€Å"That’s when I walked into her life like a newborn Mathew or Grandpa or the baby she never had† (53).Aunt Greta, from â€Å"An Indian Story† sacrificed having children of her own or remarrying beca use she wanted to take care of her nephew. She knew that she could help him move forward in life and that it would make him happy to live there so welcomed him into her home. By her being selfless, the boy was able to grow up doing well in school, learned from his mistakes, and went to college. Because of Aunt Greta’s actions the boy was able to do well for himself. If everyone in a family were selfish than no one would actually care about anybody.If Aunt Greta were selfish and didn’t allow the boy to live with her, he most likely would have dropped out of school like this stepbrother. To deal with his family issues, he probably would have gotten into drugs and or fights with other kids from his area. If his family was selfish, they wouldn’t of cared about his grades or his feelings, but Aunt Greta wasn’t selfish, she took the love that she had for the boy and took him in to help him grow as a person. Being selfless plays a big part in society also. If a person is brought up being selfless it reflects on the person they are outside of the family.In the article by Anne Lidberg she writes, â€Å"Instead of watching parades on TV or simply chatting, the Yanchunises’ spent the day serving turkey and the trimmings to hundreds of homeless people at the St. Vincent de Paul food center† (Lindberg). Their ritual has been going on for 10 years straight. The children were brought up in a home with parents who were far from selfish. By being selfless at home, they were able to teach their children to be selfless also in society. The love that the children have for their parents reflects on the selflessness that they have. Compromise within a family also ties into being selfless.When compromising with another person in the family, they can make deals that end up working for the both of them. In the visual portfolio there is a picture of a woman with her seven young children. In this picture you can infer that she is a single mother who takes care of her children to the best of her ability (74). This woman is forced to make compromises all of the time just to be able to take care of her children. When my uncle had gotten a divorce he had taken full custody of my cousin Anthony. Being a single parent with a young boy and a full time job became very difficult for him at times.My uncle was still young at the time himself, while all his friends were out in the social scene he was home, watching movies, playing games and cooking for his son. My uncle made may compromises for his son, not because he had too, but because he loved him more than anything. Compromise in a family keeps things fair and understandable. Being the only person in a family that gets to do or get what they want makes the others in the family want to envy and rebel against that member. If you’re able to compromise within the family you can keep everyone happy.Trust isn’t just about knowing someone can keep your secrets, it’s about knowing someone will be there for you when you need to talk, or knowing that they will stick around during your ups and downs. The boy from â€Å"An Indian Story† trusted his Aunt with his wellbeing. The boy also respected his aunt enough to realize that his decision to drink and get into a fight was wrong. He knew that she trusted him to make right decisions and when he went against her, he understood what he had done wrong. If there were no trust between the two he wouldn’t have cared that he went against her wishes.All that she had taught him would have been a waste of her time if she couldn’t trust him. Without trust there is no relationship. Trust is a main ingredient of a family but you also need to have respect for your family. Respecting your elders is a common saying that is used. Although respecting the members of your family that are older than you is important, you should respect all of your family no matter of their age. In the article by Kel ly Weber she states, â€Å"It is important to note that I was given this privacy because I earned it† (Weber).Kelly believes that children and teens should be respected enough to have their privacy once in a while. Although her thoughts on privacy are strong, she also makes it known that she had to earn her privacy by respecting her parents (Weber). Privacy is something that all teens strive to have, including myself. As we get older, we want to be treated as more of an adult and want to be able to be left alone when needed. Privacy is only given if someone is able to trust and respect the other. If someone wants respect, it has to be given. Aunt Greta not only respects her nephew, but his father as well.In the story â€Å"An Indian Boy,† Roger Jack is asked what he plans to do with his life and responds, â€Å"I want to be like you† (54). Aunt Greta didn’t have an issue with the boy’s father; she didn’t think that she was a better role mode l than him. She reminded him that he had a father to think about and look up too. She respected his father enough to remind him that he had a male figure in his life that he could follow in the footsteps of (54). Respect is shared throughout the whole family and is well shown in Roger Jack’s story. Without respect there is no love. When someone doesn’t respect the people around him or her, they won’t be respected.Doing and saying what they want can sometimes harm others because they are inconsiderate. That type of disrespect will not gain someone the respect that they would like to have. When people inside the family do not respect each other, there will be no love shared between the family. Everyone deserves give and gain respect. Being respected and trusted within your family unites everyone and gives everyone a well understanding of each other. Uniting the family doesn’t necessarily mean doing planned out events, it can simply be sharing the dayâ€℠¢s events with each other or eating at the dinner table.In the article by Mary Atuheire she states, â€Å"Brenda Ninsiima has a big and closely knit extended family, so as long as she remembers, she has always spent Christmas with the whole family in the village with her grannies† (Atuheire). Brenda’s family unites on holiday’s to spend time with each other. Some families are only able to spend holidays with each other, while other families like the boy from â€Å"An Indian Story,† can see their family members at any time. Although the boy had already moved out of his home, still was able to unite with his father and ask for advice after he had gotten arrested for drinking in Calgary (55-56).His father had given him the advice that he needed and listened to him while he talked about his hard times. Even though he had moved out, he still was welcomed into his father’s home, uniting the two once again. If his father had shunned him for his home he wo uldn’t of been able to reunite with him. A family that can’t unite with each other won’t want to spend time together. It’s important to unite with ones family once in a while, just to show that they still love being around one another. Being accepted within the family for who they are is an important boost to someone’s confidence.No matter what the outside world thinks of you, your family will always accept the person you are. To be accepted is to feel loved and appreciated. In the story â€Å"Looking For Work,† Soto didn’t think that his family was accepted by the outside world. He watched TV shows that showed the perfect American family, but what he didn’t realize was that those TV shows aren’t reality, no family is perfect. Soto’s family accepted each other for who they were. Although they had no money, no materialistic items, and didn’t live the life shown on TV they were still a family that loved each other through their hard times.If Soto’s family couldn’t accept their living situation or one another they wouldn’t have been a family (26-31). Without acceptance there would have been no support system or feeling of comfort. Diversity can be within a family or out in society. Diversity is to be different; not like the rest. Whether being diverse within your family means that you have a different sexual preference, different religion, or different heritage, your family will still accept you for the person you are. Soto’s sister expresses. â€Å"They’ll never like us† (Soto 30).Soto’s idealistic family was the white American families that were shown on comic television shows. These families would all be dressed for dinner, had toys that would fill their closets, didn’t get beatings or got into arguments, and were kissed and tucked into bed every night. His family was the typical Mexican American family back in the 1950’s that weren’t respected, had no money, and had to work for the bare minimum. Soto believed that the differences between his family and normal American families, was the reason why in his mind, his family was â€Å"wrong†.Without diversity, all families would be alike, all traditions would be the same, they’re would be no differences. When everyone is the same, life becomes boring. The best part about having diversity in this world is for the simple fact that everyone can learn about different things from each other. Although diversity is a big part of being a family, so is conflict. In situations of conflict aren’t always within the family, but within society also. Some people in the world don’t accept the fact that people are different which causes conflict. In the article by E. W.Carp states â€Å" Leading experts challenges the myth that lesbians and gay men are unfit to adopt† (Carp 1539). Being apart of a family with same sex parents cau ses conflict in society. Some people in this world are unable to understand that no matter what sex people are, they are still capable of having and raising a family with all the love they have inside of them. Some families who have a mother and a father are more unfit to raise a family than families with two mothers or two fathers. Gays and lesbians are afraid to try and adopt because of the conflict they might cause in society.Diversity in society may cause conflict but, conflict makes the world grow, making it not so much of a negative aspect. Soto on the other hand, causes a conflict within his family when he brings up his idea to get dressed up for dinner. Although he is considering the fact of trying to act more sophisticated, his sister believes that he shouldn’t care what people think of their family because, society will never like them for who they are (Soto 29). Even though Soto started a conflict between siblings, people in this world will start an argument becaus e of the way some one acts or looks.Some may think that a family that doesn’t deal with conflict is a drama free family, but without a conflict once in a while a family wouldn’t be able to overcome their problems together. These conflicts, either external or internal, make a family stronger. A family joins together as one to love, trust and accept each other through even the hardest of times. Love within families is the largest component to making up a family. Consider love like a tree, the branches are made of selflessness, compromise, trust, respect, unity, acceptance, diversity, and conflict.Without the branches on the tree, it wouldn’t look like a tree. The same goes for a family. Love without the rest of the components wouldn’t be considered a family. Family in my opinion, are the only people who welcomed you into this world and will be the only people who stay by your side through the journey life brings. It’s important to always remember tha t your family will love you for what you do, trust you to do your best, and accept you for who you are. Works Cited Carp, E.

What is Anthropocene?

The videos In the website â€Å"Welcome to the Anthropocentric,† discusses about Anthropocentric. Questions that I will answer are what Is Anthropocentric? Why Is It label that way? What are some patterns in the era that are exhibited? Along with why should we care about mass extinction? Anthropocentric is a new geological epoch dominated by humanity.The word â€Å"Anthropocentric† is given its name because human activity has polluted the sea, caused mass extinction of animals and plants, and changed the Earth's natural cycle. Some of the patterns that this era has exhibited re the changes in the Earth's life support system, such as changes within the environment. For example, temperatures and sea levels are changing due to global warming, level of greenhouse gases is rising, and changes In the global water systems Is through damming, extraction, arrogation, and climate change.Furthermore, population, production, and consumption have grown exponentially. We are moving m ore sentiment than natural erosion and rivers. Therefore, there Is a whole In the Ozone and this Is causing us to lose bloodlessly. We should be concern about the mass extinctions of organisms because without hem, we will not have any support for food supplies and the environment. Especially, the functioning of the ecosystem.However, I believe that this catastrophe has been going on for years, however some people have no idea where this will lead us to. We should do something about this and that carries with responsibility. We have the option to stop and act upon the current rate of extinction with measures that will prevent habitat loss, and with regulations and rules that will provide species the kind of safety net that humans have. Most importantly, we must adapt to change.

King Lear Essay Example | Topics and Well Written Essays - 750 words - 4

King Lear - Essay Example King Lear is a person who has many fine inclinations, however, he became a victim of wrong development. The power he possessed as a master over life and death of his citizens, the flattery and general servility strongly developed his self-conceit and vanity. All his goals were directed not at great deeds and mutual benefit, but at the satisfaction of his own desires. But with all his despotism and self-love Lear, even at the beginning of the tragedy, doesnt belong to people for whom the power and wealth are the top priorities. Most of all he wanted to be human. However, his own understanding of dignity got the perverted expression, it developed into self-adoration that reached an extreme point. The division of the kingdom between the daughters and refusal of his property, the deed that seemed reckless at first sight, had the internal logic. Lear believed that all the people loved him as a person, he wasnt able to differentiate those who really fed for it love, from those who loved only a monarch in him. He decided to give the property to his daughters, to become free of royal greatness and to take pleasure in human greatness. He was sure that without the power and property he will have the same respect and love; moreover, he wanted to have moral satisfaction being appreciated as a human. Believing in his superiority, he fondly thought that he remained the king in moral sense even if he was not a king any more. Therefore, making the division of the kingdom, he demands from daughters the expression of love to him. But, in reality, he demands not love, but obedience to his will, because he didnt get used to take into account feelings and desires of other people. Therefore, he turns out Cordelia whose answer did not satisfy him: â€Å"And yet not so; since, I am sure, my loves More richer than my tongue.† (Act 1 Scene 1), and gives all the property to two older

A Rhetorical Analysis of James Ladsen and Joseph Epstein Essay

A Rhetorical Analysis of James Ladsen and Joseph Epstein - Essay Example The essay "A Rhetorical Analysis of James Ladsen and Joseph Epstein" talks about the hubris that can be defined as tempting to face, or otherwise thumbing one’s nose at that which is already predetermined. This ancient Greek term for insolence and arrogance to fate plays a powerful role with respect to the way how current culture is defined and practiced. Essentially, the culture that exists within the United States, and to a large part around the globe as a result of globalization, can be understood as one that places a fundamental level of importance on maintaining youth and vitality; even at ages in which these are all but an unrealistic hope. Accordingly, the following analysis will seek to engage the reader with a rhetorical response to Ladsen’s â€Å"The Natural Order† as it relates to the idea of hubris. Likewise, this rhetorical response will be compared and contrasted with Joseph Epstein’s essay â€Å"Perpetual Adolescence†. Through such a level of analysis, it is the hope of this author that the reader will come to gain a more valuable and nuanced interpretation of why our current culture is so fixated on the idea of perpetual youthfulness; and whether or not this is a positive or negative attribute. Firstly, in terms of Ladsen’s story, entitled â€Å"The Natural Order†, the author represents the internal and external dialogue that is taking place between a middle-aged married man and one of his longtime best friends. The middle-aged married man is indicative of what might be termed as a â€Å"conservative†.

CRJS 205 Introduction to Criminal Law Essay Example | Topics and Well Written Essays - 250 words - 1

CRJS 205 Introduction to Criminal Law - Essay Example Having difference remedies in civil and criminal cases implies different penalties for prospective offenders. In civil cases, a defendant who loses a case if immune from incarceration or a jail sentence as compared to losers in criminal cases. In general, a defendant in a civil case is only required by law to pay compensation to any losses incurred by the plaintiff (Standler, web). Punishments offered by at the civil and criminal level for a similar case should not correlate in any way. The main reason why the two punishments should not correlate is that civil litigations are aimed at restoring the plaintiff to the initial financial position while criminal punishment offers emotional consolation and therefore the two remedies are not related or equivalent. Secondly, in criminal cases the state bears the burden of proof while a plaintiff shoulders the burden of proof in civil cases and the two have different capabilities (Standler, web). Finally civil cases corporate as the defendant while criminal cases have individuals as the defendant therefore available punishments will have different effects on the two

Applied Economics Essay Example | Topics and Well Written Essays - 250 words

Applied Economics - Essay Example Concerning the four countries in question it is evident that the rate of growth of the Gross domestic product varies from one country to another (The world bank, 2014). Based on the comparison among the four countries it is apparent that a high volume of Money at LCU corresponds with a low gross domestic product and a low volume of money at LCU corresponds with a high gross domestic product. Money at LCU is one of the significant economic indicators since it refers to the money that is in circulation (Econstats, 2014). In this case, financial transaction tax will have a direct impact on the money at LCU. In this case, financial transaction tax will lead to a decrease for money at LCU. Based on the relationship between money at LCU and GDP a reduction in the money at LCU will raise the rate of GDP for a given country. Consequently, this will have a reduction in money at LCU will lead to reduction in inflation since it will reduce the spending habits of residents in a country. On the o ther hand, an increased local currency unit volume will increase money supply, which may lead to inflation (Eisenstein, C. 2011, 295). In conclusion, an analysis of the four data variables Inflation, money at its local currency unit (LCU), and revenue collected form tax and the gross domestic product outlines that financial transaction tax can have an impact on the economy of a country. Because financial transaction tax can regulate the money supply of a country, it can have an effect on the economic activities of a country. As a result, financial transaction tax can be used to stabilize economic conditions of a

Video game console and Nintendo Essay Example for Free

Video game console and Nintendo Essay In the world of video games, Nintendo has been a household name for nearly three decades. After all, it was one of the pioneers of home video game consoles with the Nintendo Entertainment System in the early 1980s. It continued as the market leader with its Super Nintendo and Nintendo 64 systems. But in the mid-1990s, all that began to change. Along came Sony with its Playstation and Playstation 2, and Microsoft introduced the xBox. Before long, Nintendo was reduced to a fraction of its former glory, running a distant third in a highly competitive market. What happened? In certain respects, Nintendo fell prey to the industry model that it had created. More advanced technology led to the creation of more powerful gaming consoles, which in turn paved the road for more sophisticated games with more realistic graphics. As each new generation of product hit the market, Nintendo found that it could not keep up with more technologically advanced rivals. While more than 120 million Sony PS2s became fixtures in homes, apartments, and dorm rooms around the world, Nintendo moved just slightly more than 20 million GameCubes. As the most recent generation of gaming platforms from the gaming industry’s â€Å"big three† came to market, many industry insiders figured Nintendo was destined to continue its downward path. Sony’s PS3 and Microsoft’s xBox 360 were so advanced that it looked like Nintendo was due for another drubbing. Oh what a difference a couple of years makes. For Nintendo, everything is now coming up Super Mario Bros. â€Å"flowers. † Last year, revenues and profits were up by 73 percent and 67 percent, respectively. In the last couple of years, during a time in which the Nikkei Stock Average fell nearly 25 percent, Nintendo’s stock price tripled. In fact, Nintendo’s stock price rose so high during 2007 that its market capitalization exceeded that of the Sony Corporation. On that measure alone, Nintendo became the second largest corporation in Japan, trailing only Toyota Motor Company. How did this struggling number three player go from product loser to product leader in such a short time? FROM PRODUCT LOSER TO PRODUCT LEADER Most people probably don’t know that Nintendo was founded way back in 1889. Obviously, Nintendo did not make video games back then. It began as a playing cards manufacturer. But it also found success in hotels, packaged foods, and toys. When it came time to revive itself as a veteran in the video game industry, Nintendo did something that it had done time and time again. It focused on customers to find true opportunities. For the video game industry, â€Å"the customer† typically means one of two groups: the 18 to 35-year old hard-core gamers and the children/teenagers. The industry earns most of its revenue and profits from these core consumers who spend a great deal of time and money enhancing their virtual skills. Over the years, as hardware became more sophisticated and games more realistic, these tech junkies were all the more pleased. In the process, Nintendo watched its revenues slide and its rivals strengthen. It realized that it could not compete against technologically superior products. So when it set out to develop the Wii console, it didn’t even try. Instead, it focused on something the others were ignoring. It set its sites on the masses. â€Å"Nintendo took a step back from the technology arms race and chose to focus on the fun of playing rather than cold tech specs,† said Reggie Fils-Aime, president and COO of Nintendo of America. â€Å"We took a more intuitive approach and developed something that could be fun for every member of the family. † 298 Part Three | Designing a Customer Driven Strategy and Mix placed on a separate scale. The light bulb went on as Sawano thought about the possibility of tracking a user’s shifting weight on a game pad as they shimmied and twisted their way through virtual worlds. That game pad is now called the Balance Board and lies at the heart (or rather the foot) of the Wii Fit’s portfolio of exercise applications. Users can do aerobic, strength training, balancing, and yoga exercises all in realistic virtual settings. â€Å"It is now possible to go beyond the fingertip controls of past games and now use your whole body,† Sawano told a crowd of game developers. The Wii Fit also facilitates exercise programs as it tracks and analyzes individual performance over time as well as keeping track of stats like weight and body-mass index. Perhaps the most promising part of the Wii Fit is not that it continues to broaden an ever-growing market segment. In addition, the Balance Board component has the potential to be integrated into a nearly limitless number of applications. Already, Nintendo has developed ski jump and slalom games. It’s only a matter of time before Nintendo develops a Balance Board version for just about every sport imaginable. Releasing hit after hit, Nintendo has vaulted to the top of the Wall Street Journal’s latest Asia 200 survey. Placing first in the â€Å"Innovative in Responding to Customer Needs† category, the company placed second overall, trailing only Toyota. For a company that hadn’t placed in the top 10 since 2002, the sudden turnaround is a telling demonstration of consumer confidence. For the Wii, this meant that Nintendo had to do more with less. The Wii boasts a humble combination of low-powered processors and a standard optical disc drive. Compared to the powerful, state-of-the-art chips and high definition lasers contained in the PS3 and xBox 360, the Wii’s graphics are out right scrawny. But at the core of the Wii’s broad appeal lies a revolutionary motion-sensing wireless technology that forces the once sedentary gamer to get up off the couch and get into the game. The Wii controller resembles a television remote. This feature was no accident as Wii designers correctly speculated that the familiarity of a TV remote would be more inviting than the more typical and complex video game controllers. The Wii’s basic software also allows users to custom design avatars from a seemingly infinite combination of characteristics. With this configuration, users play tennis, go bowling, and hit the links by swinging the controller like a racket, ball or golf club, all with characters resembling themselves. The Wii met with immediate and drastic success. Entering the market after the release of the xBox 360 and the PS3, Wii consoles flew off the shelves. Not only did the Wii’s contain an enticing combination of features, it also had a cost advantage. Microsoft and Sony had priced their offerings in the stratosphere. And even at $599 for the top and most popular PS3 model, Sony was still losing hundreds of dollars on each unit that it sold! Nintendo’s low-tech approach allowed it to earn a hefty profit and be the low-price leader at only $250. With such a favorable benefit-to-cost ratio, the Wii easily won the launch phase, outselling each of the two competing consoles by nearly two-to-one in the first few months . 9 Chapter CXXXX 43550 Page 298 08/15/08 MD SECURING THE FUTURE Although the success of the Wii has largely been attributed to attracting non-traditional gamers, hardcore gamers have hardly been absent. In fact, many of the industry faithful saw the Wii as a relatively cheap second gaming platform—as a nice diversion from more graphic-intensive games. The Wii also has the nostalgic advantage of appealing to the gaming elite with characters they grew up with, such as those from the Mario and Zelda franchises. But developers and executives at Nintendo are not content to sit back and risk having hardcore gamers lose interest. Part of Nintendo’s future strategy includes games focused on more serious gamers. CEO Satoru Iwata shocked the industry last year when he announced that Nintendo would soon add games from two Sony allies: Capcom’s Monster Hunter series and Square Enix’s Final Fantasy Crystal Chronicles. The release of these titles will do more than appeal to traditional gamers. It will elevate the Wii’s image from that of a machine with little firepower to one that will run the industry’s most advanced games. Said one game industry analyst at a tradeshow sneak preview, â€Å"It’s symbolic. I didn’t think the Wii could handle this type of game. Everyone in the room today saw that it can. † As Nintendo has successfully attracted an untapped audience of gamers over the past few years, it has done more than revive its business. It has transformed a market. The competitors that once trounced Nintendo now find that they must play catch-up. Both Sony and Microsoft are now developing easierto-play games that depart from their usual fast-action fare. Game publishers, including powerhouses such as Electronic Arts Inc. , have started putting more resources into developing games for the Wii. And even small, independent shops are getting into the action as Nintendo’s download channel reduces barriers to entry. All this is causing an already huge $30 billion industry to swell. NOT JUST A FAD Although the Wii was an instant smash hit, many analysts wondered whether or not its appeal would hold up. That speculation began to subside when retailers were still having trouble keeping the Wii in stock more than a year after it was introduced. In its first 18 months, Nintendo moved more than 24 million Wiis. Even though the xBox 360 had been on the market a full year longer, it had sold only 19 million units. And Sony, once the undisputed industry champ, placed only 12 million PS3s. Nintendo’s willingness to reinvent what a video gaming system can mean continues to drive Wii sales. For example, the Wii can scan weather, news, and Web sites through a wireless Internet connection. Through the Wii Shop Channel, an iTunesstyle store, customers can download classic Nintendo games as well as games from independent developers. But in its pursuit to break gaming boundaries, Nintendo has also relentlessly pursued new applications for the basic motionsensing technology. A plastic rifle contraption allows users to realistically play shooting gallery games. Snapping the Wii controller into a steering wheel has made driving games all the more electrifying. And tiny in-controller speakers add touches like the sound of an arrow being shot while the TV makes the â€Å"thwack† of that arrow hitting its target. But perhaps one of the greatest strokes of creative genius in Nintendo’s continuing stream of new applications is the Wii Fit, an add-on device targeted directly at women wanting to lose weight or keep in shape. The idea for the Wii Fit came to Takao Sawano, general manager of development for Nintendo, as he watched sumo wrestlers being weighed in for a television match. The tubby athletes were so heavy that they had to have each foot Company Cases Chapter 9 | New-Product Development and Product Life-Cycle Strategies 21 299 Chapter 3. In which stage of the product life-cycle is the Wii? Based on that stage, is Nintendo employing good marketing mix strategies? Simon Jeffery, president and COO of Sega of America, summarizes why Nintendo has been successful and why the rest of the industry must keep up. The fundamental interface in games has always been a controller, and Nintendo is bringing opportunities to developers to think about how interactions use motion. That has opened doors of creativity throughout the video game business. Nintendo’s success is about creative leadership and the willingness to do things differently. As long as Nintendo can stay focused on these elements that have returned it to its throne, it will reign for a long time to come. 4. Develop a strategy for the Wii’s next product life-cycle phase. 5. Discuss the potential threats to Nintendo’s future success. What will help Nintendo avoid a premature decline for the Wii?

Exploring The Culture Of Denmark Sociology Essay

Exploring The Culture Of Denmark Sociology Essay My great, great grandfather, Paul Christian Lautrup, a single, caucasian man of 35, migrated from Denmark to the United States. He came from a wealthy family originating in the Danish culture and was educated to become an architect. He was expected to continue in the occupation that his nuclear family had persuaded him to train for in order to be kept in the family will. If he were to move away and not pursue the career that had been expected of him, he would be removed from the family will and lose all his inheritance. Against his familys wishes, he chose to leave Denmark to escape their career demands and to pursue his own interest. He moved to the United States in 1880 to follow his dream of becoming an actor. He made Washington DC his home, where he met his wife Delia whom he had 6 sons with. Unfortunately, he did not succeed in becoming an actor and settled for becoming an architect in the US. This is rather ironic, because he ended up moving away from Denmark and losing all his inheritance only to become an architect in another land. (Lautrup, Paul). Denmark is a small nation nestled within the Scandinavian countries located on the European continent. Denmark, also known as the Kingdom of Denmark, has a tiny population of roughly 5.3 million citizens with only a 69km land border that is shared with Germany; this is the only land connection that Denmark has with Europe through its only peninsula and largest region, called Jutland. Also, Denmarks main realm has 5 major islands, which support most of Denmarks population, accompanied by 406 minor islands. Only around 90 of the 406 minor islands of Denmark are known to be inhabited. Also, Greenland and the Faroe Islands are part of the Kingdom of Denmark. (Bendure, Glenda, and Ned Friary) They are both located in the Atlantic Ocean and considered to be autonomous regions within the Kingdom of Denmark; both have very small populations under 100,000 citizens. Copenhagen is the capital of Denmark and is the nations largest city. Copenhagen is also the biggest and most modern city in all of Scandinavia. Scandinavia includes the countries of Sweden, Norway and Denmark. Over 70% of Denmarks population lives in an urban environment, while most of the population consists of people of Danish ethnicity, although there are a growing number of immigrants from Asian and African nations. (Bendure, Glenda, and Ned Friary) The North Sea is to the west of Denmark and the Baltic Sea is to its east. Denmark is separated by its northern, neighboring, Scandinavian nations of Norway and Sweden by the Kattegat and Skagerrak straits. Sweden, the second closest neighbor to the Danes is cut off from Denmark by only 5km of water named the Oresund strait. Denmarks climate is humid and chilly during the winter, with an average temperature of 34 degrees F and during the drier, summer months, the temperature averages 72 degrees F. (Bendure, Glenda, and Ned Friary) Denmark has gently rolling hills with fertile soil that are at a close range to sea level with no true mountains throughout the nation. There are many lakes, rivers, streams and moors, which create an ideal environment for agricultural prospects. There are no extreme changes in climate due to the Gulf Stream that flows up from the south over Denmarks western borders. Since the land is accessible to the sea, it is a prominent supplier to the ship industry is Northern Europe. Denmark has no point on its land that is more than an hours drive from the sea. There are numerous bays and inlets, which creates gainful opportunity for their prosperous shipping industries. (Bendure, Glenda, and Ned Friary) Some especially important Danish landmarks include: The Tivoli Park, the most popular amusement park in Denmark, Fredericksborg Castle, and The Royal Theater. Hans Christian Andersen, known for his fairytales with relatable moral teachings and Karen Blixen, known for short tales and life memoir are among many famous writers of Danish literature. Soccer is Denmarks national sport, but sailing, cycling and rowing are also Danish favorites. The national language is Danish, although, many Danes can speak English and/or German at least on elementary levels. (Bendure, Glenda, and Ned Friary) The Krone is the source of Denmarks monetary exchange and the Euro has not yet been accepted, due to the nations suspicions that switching over to the Euro will have a detrimental effect on their beloved social welfare system, which the citizens of Denmark take great comfort in. Denmark maintains the oldest continual monarchy in Europe and the second oldest in the world. Queen Margrethe II is the current Queen and head of the constitutional monarchy in Denmark. She is only the second queen to rule the monarchy throughout the entire history of Denmark. The Danish community is very proud of their form of government, their royal family and their Dannebrog, which is their national flag. Danes are not a people who are easily insulted, but one way to offend them would be to criticize anything concerning their Dannebrog, royal family or form of government. (Bendure, Glenda, and Ned Friary) The subsistence strategy relied upon most in Denmark today is information. Higher education, the promotion of environmentally green solutions, literature and the fine arts are all very important to the Danish people. (Bendure, Glena, and Ned Friary) Over 77.3% of the jobs held by Danes are part of the information subsistence strategy through service-related jobs. (CIA The World Factbook) Since education is paid for by the heavy taxes the Danish people submit to, it is financially obtainable for anyone with high enough scores to continue their education into any of Denmarks universities. There are 5 universities for the citizens to choose from which include: Copenhagen, Roskilde, Odense, Aaloborg and Arhus Universities. Queene Margrethe II and her son, Crowned Prince Frederik are graduates of the elite Arhus University. Danes also have the option of continuing their education by attending community colleges or vocational technical schools. Some of the occupations that Danes are going to school for include: maritime studies, nursing, physicists, architects, social services, literature, history, religion, photography, teaching or various other information service occupations. (Bendure, Glenda, and Ned Friary) These jobs all rely on technology and tools such as computers, cameras, high-tech printers, internet connections, satellites, sterilized medical equipment, body-image scanners, reference texts, cell phones, writing utensils, specialized uniforms and printers are just a few examples of the many advanced tools that are necessary for these various fields of information subsistence strategies. For example, a teacher would use tools such as a blackboard, a computer projector, chalk, erasers, videos, books and printers in order to relay information to teach her class a particular subject. Of course, these types of tools and technology are used all over the nation in rural and urban areas, but perhaps slightly more in the densely populated regions. Division of labor can be divided up in a number of ways in regards to the information subsistence strategy. For example, a dean of a college may oversee that the college professors are following the guidelines for teaching classes from the code of ethics in their employee handbooks. The professors oversee the progress of skills and information learned by his/her students. The students attempt to maintain good grades in their class by completing all their schoolwork to the best of their ability. Division of labor usually depends on the socioeconomic status and education acquired. However, in Danish society, social caste or social status does not create an obstacle in regards to whom can do what type of career. The citizens have a silent understanding amongst one another that every individual within the nation is important and should not be treated differently whether the citizen is a doctor or a trash man. The opportunity to pursue an information career is equally welcome to men and women; gender does not hinder occupational roles in Danish society. (Bendure, Glenda, and Ned Friary) The second most important subsistence strategy amongst Danish society is industrialism in which some 20.2% of the population is employed. (CIA The World Factbook) Some examples of the products manufactured are ships, boats, ceramics, silverware, furniture, chemicals, paper, fish products, dairy products, canned ham, electronics, textiles, concrete, marine engines, radio and communication equipment, toys, glass, pharmaceuticals, agriculture/forestry machinery, electrical products and diesel engines. Most of the industrial facilities that produce these Danish goods are located in more urbanized areas throughout the country. Many of these products require special skills used by laborers that have been trained at either a vocational school or through a type of apprenticeship training program paid for by the Danish government. Particular tools and equipment are necessary for creating these products that can include: pulleys, compressors, mixers, castes, hammers, nails, scissors, ovens, k ilns, saws, test tubes, Bunsen burners, beakers, glue, electrical wiring, assembling machines, counting machines, computers, charts, slicing equipment, turbines, converters, nets, sails, anchors, food processors, milking machines and generators. (Bendure, Glenda, and Ned Friary) For instance, if a plant is producing paper products, large, metal rollers, would need to be used in order to press the paper into the desired thickness. Also, mixers would be used to stir and prepare the paper pulp in order to pour it into the appropriate screening containers. A specialized machine would be necessary to wrap the finished paper product for distribution and sale. Distribution of labor depends on experience, skill level and seniority of the workers involved in the particular industry. Owners of factories and heads of departments oversee the quality and efficiency of production, which is reported from the supervisors. Supervisors organize, direct and monitor manual labor workers in their duties. Manual labor workers attempt to create products at a company-desired rate and quality, while not bearing the responsibility of their overseeing their co-workers. The third of the most important subsistence strategies used in Denmark consists of agriculture. The main products grown in The Kingdom of Denmark include: sugar beets, barely and wheat, grains, rapeseed, fruits, vegetables and flowers. (Bendure, Glenda, and Ned Friary) Agriculture is most commonly practiced by only 2.5% of the population and is normally achieved in rural areas of the country. (CIA The World Factbook) Training apprenticeship programs and information passed down through family generations are used to teach agricultural methods. (Bendure, Glenda, and Ned Friary) Some technologies used for agriculture include items such as combines, separating machinery, generators, irrigation systems, planting machinery, tractors, plows, fertilizing distributors, storage units and computers for analyzing crop quantity and quality. Irrigation systems are used to water the large expanse of crops, plows are used to till the land for preparation of planting seeds and computers are used to keep record of seasonal harvest yields and perhaps even profit margins. There are over 60,000 family-owned farms in Denmark (Bendure, Glenda, and Ned Friary) and the division of labor is shared by the family and or corporation that own the farms along with the hired employees who are used for cleaning and fixing equipment, sorting crops, running machinery, irrigation and maintaining the health of the crops. The family or corporation of the agricultural operation oversees the employees or hires a supervisor(s) to ensure that the agricultural laborers are working efficiently. The supervisors or owners of a farm may calculate the quantity of crop and the value it yields per season. The agricultural land owners or supervisors also may keep track of the laborers improvement or lack of effort on the job. The farm laborers will tend to any manual labor that the agricultural operation needs completed while only having to be responsible for their individual production. The division of labor in agriculture is based mostly on skill, seniority and ownership. The fourth most important subsistence strategy in Denmark is pastoralism of which is included in the 2.5% of the nations population that maintains a career in agriculture. (CIA The World Factbook) The animal goods raised and produced in the Kingdom of Denmark include: canned ham, butter, cheese, fish oil, fish meal and milk through the use of fish hatcheries and typically family-owned farms. As in the agricultural subsistence strategy, pastoralism is either passed down through families or learned through an apprenticeship training program. (Bendure, Glenda, and Ned Friary) Some tools used for pastoralism include: fences, watering/feeding troughs, barns, herding rods, milking machines, slaughtering equipment, medical tools, labels, hoof clippers, lead ropes, halters, hoses, generators, heaters and computers. Fences are used to keep the livestock confined to a desired location, animals are put in barns to protect them from predators and the occasional harsh outdoor elements and heaters may be used in the barns to keep a sustained temperature that is more suitable for the livestocks health. As in the agricultural subsistence strategy in Denmark, the division of labor amongst workers in pastoralism is based on skill level, seniority and ownership. For example, the owner of a herd of swine may hire a supervisor or herd manager in order to keep track of the manual laborers and also the efficiency of herd quality, health and maintenance. The owner of the swine operation may calculate yearly profits, upkeep costs and decide what to pay employees based on their skill levels. The employees without management skills, the hired hands or basic herd tenders will be responsible only for the safety, feeding and order of their set group of livestock that they are to have authority over. Denmark has a centralized political organization and maintains a constitutional monarchy as a political model. A constitutional monarchy can only be led by offspring of the current king or queen after he or she is deceased. It is a requirement for the king or queen of Denmark to be a member of the national church. A single-chamber parliamentary runs hand-in-hand with the constitutional monarchy. The prime minister, currently known as Lars Lokke Rasmussen, leads Denmarks political organization with the indirect support of all 179 parliament members and direct assistance from the cabinet ministers who lead numerous political departments throughout the nation. Voting age in Denmark is 18 and all parliament members are elected for a term of 4 years, unless state minister forces a new election before the 4 years is completed. It is the duty of the members of parliament to come to consensus on decisions to enact or not enact new legislation and the duty of the prime minister to carry the d ecision to action, however new legislation cannot be enacted fully until Queen Margrethe II writes her finalizing signature on it. There are typically around 12 political parties that make up the single-chamber parliamentary system of the Danes. The top 2 of these major political parties consist of Social Democrats and Liberals-a right-of-centre part. Social Democrats seem to be the most popular considering the fact that they are tied heavily to the belief that all Danish citizens should be granted security by maintaining the comforts of social-welfare programs, but of course, these are safety features only made possible by very high taxes to the Danish people. (Bendure, Glenda, and Ned Friary) The royal constitutional monarchy headed by Queen Margrethe II has control of the executive powers, while legislative powers are for the most part, granted to the parliament and judicial powers are carried out by the courts of Denmark. Denmarks military branches include: a home guard, an air force, a navy and a national rescue corps. Military members are usually enlisted for 4 months to a year of service. During war times, the Danish military acquires 58,000 members, but during peace times, there are roughly fifteen thousand participating members. The Danish military ranks are usually based on mandatory enrollment in order to be ready when an emergency arises. Denmarks police force has about 10,000 law enforcement officers who are known for their more civilized, calmer approaches to domestic disputes by using advanced communication skills and maintaining close, positive relationships with the overall communities they work in. (HOG, ERLING, and HELLE JOHANNESSEN) One form of internal political control in Denmark is the enforcement of laws through the judiciary court systems. Although, crime in Denmark is very low and it is not normal for a Dane to even consider breaking the basic laws of the land. An example of externalized political control would be the decision of the Danish Parliament to not accept the Euro as Denmarks new currency, even though Denmark is a member of the European Union. Internalized political responsibilities of Denmarks parliament involve the maintenance of social welfare programs that protect all Danish citizens regardless of socioeconomic status. The externalized responsibility of the parliament consists of maintaining peaceful political connections with the European Union and other nations in regards to preserving a secure way of life for its citizens and also keeping a cohesive relationship with national allies for added protection. After all, Denmark is a very small nation and it would be beneficial to preserve as mu ch peace with as many nations as possible. (Bendure, Glena, and Ned Friary) The economic system of Denmark is based on negative reciprocity due to the use of capitalism throughout the nation. Capitalism is used by the Danes to generate profit through sales of products from private businesses and corporations to customers. Redistribution is also used throughout the Danish culture in the form of health care and educational needs. Danish pay high taxes that allow them to enjoy the freedoms of free health care and education of any type. This allows the Danish citizens to give and take as they need, for example, all citizens are taxed regardless of how much income they generate, but it is possible that not all of them will use the free education opportunities or the free health care services during their lifetimes. (Bendure, Glenda, and Ned Friary) Market exchange is also used through capitalism in Denmark in regards to having the freedom to set up a private business and gain profit from it without limit, which is a prime example of capitalistic market exchange. Denmark uses both socialism and capitalism, but the predominant economic system would have to be capitalism. This is true, because Danes are free to pursue their own interests through careers that will allow them to generate profit without limit to the individual. Although, socialism is prevalent in the way Denmark controls and maintains social welfare for the citizens in order to provide free and easily accessible, equal-quality health care and education to all Danish citizens regardless of social or economic status, gender, religion or ethnicity. (Bendure, Glenda, and Ned Friary) The primary economic sector, which involves extraction of resources form the land, also known as mainly agriculture in Denmark, makes up 2.5% Danish employment. (CIA The World Factbook) A few of Denmarks exports consist of canned ham, butter, cheeses, beer and processed fish products of which are brought forth through agriculture, pastoralism and industry. (Bendure, Glenda, and Ned Friary) The nations secondary economic sector, which involves processing of goods, also known as industry makes up 20.2% of the Danish workforce. (CIA The World Factbook) Denmark manufactures machinery, chemicals, furniture, electronics of which are exported all over the world. (Bendure, Glenda, and Ned Friary) The tertiary economic sector, which involves services, makes up 77.3% of the working Danish population. (CIA The World Factbook) A few of Denmarks popular service industry jobs are found in the fields of architecture, nursing, teaching, physics, environmental science, literature and social sciences. Denmark enjoys the highest Gross Domestic Product in Europe and maintains one of the highest standards of living for its citizens compared to all nations in the world. Unemployment is very low and over half the country is employed with the reassurance that health care and education will not be a challenge to pay for. Denmark relies heavily on the income from its exports and puts a great deal of value on maintaining its social welfare programs. (Bendure, Glenda, and Ned Friary) Denmarks most common religious organization is Evangelical Lutheran, of which over 90% of Danish citizens belong to. Evangelical Lutheran is a denomination that is part of a national church, supported by the state called the Danish Peoples Church. Only about 5% of Danish people actually attend church weekly; most Danes only participate in church services during important religious holidays such as Christmas or Easter. Evangelical Lutheranism is a monotheistic religion, which means that they worship only one god. (Bendure, Glenda, and Ned Friary) Other religious organizations that exist in Denmark consist of Catholicism, Judaism and Islam, which also practice monotheism. Also, a small percentage practice forms of religious organizations such as Buddhism, Sikhism and Hinduism, which promote polytheism, the worship of many gods. It is ironic that the overall Danish society does not have a strong faith in the god or gods of their religious choice, yet at birth most of the country is automatically enrolled as a member of the national church, also known as the Danish Peoples Church. Their enrollment is expected unless they belong to a religion other than Evangelical Lutheran. It is a requirement that the current king or queen of Denmark be a member of the Evangelical Lutheran religious organization. (HOG, ERLING, and HELLE JOHANNESSEN) Danish churches are typically located in close proximity to all Danish towns and are encompassed by graveyards. Evangelical Lutheran religious organizations have sermons and worship in churches on Sundays. Their ceremonies include a minister, a servant, an organist and a cantor. Evangelical Lutheran important ritualistic ceremonies include: weddings, confirmations, funerals and baptisms. It is expected that most Danish churches have fairly low attendance rates during Sunday services. (HOG, ERLING, and HELLE JOHANNESSEN) Throughout the Danish social organization, monogamy, the practice of marriage to single spouse, is the most accepted and nationally predominant form of union. Marriage is important in regards to the most common form of religion in Denmark, Evangelical Lutheranism, yet because Danes are not known for being highly involved in the practices of their religious organizations, there is a loose view on marriage and when it should be chosen, if at all. It is common for a Dane to cohabitate for years, have offspring and not be married until many years after. Therefore, it is not uncommon for Danish households to have illegitimate children born outside of wedlock. (Bendure, Glenda, and Ned Friary) If Danes do decide to marry, it is usually not until they are in their very late twenties or early thirties. Danes do not participate in arranged marriages, an event where parents choose a marriage partner for offspring, instead, single Danes choose their own marriage partners through the anthropological term love match. Endogamy, marriage created within ones own organized cultural group, is practiced in Denmark as well as exogamy, marriage outside ones own organized cultural group. Most often, Danes marry other Danes of their own ethnicity, yet those who choose to marry outside of Denmark or ones ethnicity is not condemned within the Danish societal organization. (Bendure, Glenda, and Ned Friary) Post-marital residence, pertaining to where a bride and groom reside after their marriage ceremony, only pertains to the Danish societal organization in the sense that marriage partners typically practice neolocal forms. A neolocal form of post-marital residence can be defined as the event of taking residence in a home that is set apart from the married couples families. Other forms of post-marital residence, such as patrilocal, the act of a married couple living close to or with the married males family of his father, or matrilocal, the practice of both marriage partners residing with or in close proximity to the married females family of her mother, are not commonly practiced. Marriage in modern Denmark societal organization, is not required, nor is it a high priority. (HOG, ERLING, and HELLE JOHANNESSEN) Therefore, post-marital residence is not of great importance, It is only on a neolocal sense, considering that Danes learn to be very independent at a very early age, while maintaining a close-knit family on an emotional level. The most important family type for Danes is the nuclear families containing dependent children, a wife and a husband. Even though the idea of marriage in the Danish societal organization is very loose and laid-back, out of all couples living together in Denmark, most of them are in fact married. Extended family, consisting of aunts, uncles, cousins, grandparents and other individuals with marriage or blood relating them, are also important, but not as high a priority as the nuclear family. Most Danish nuclear families are small, having two or less dependant offspring. Privacy is valued greatly by Danes, especially when it comes to the nuclear familys home. It is rare for a Danish family to invite a guest to their home whom they have not known for a great while . (Bendure, Glenda, and Ned Friary) Each of the nuclear family members generally has their own private room in the home along with the rooms for meeting, such as the kitchen and larger family rooms. In Denmarks societal organization, descent is traced by using a lineage, which is used by connecting all ancestors back to a single, original ancestor. Descent in Denmark is traced in this way, because last names are important links to ancestry. Although last names are taken from the male within a married couple, patrilineal descent, tracing only by acknowledging male individuals as ancestors, is not used, because all genders are included when tracing Danish ancestry. (Bendure, Glenda, and Ned Friary) When referring to kin, relatives connected by marriage or blood, Danish citizens value ties with both the mothers and the fathers side of the family, which is called bilateral kinship. Bilateral kinship is important for Danes, because both nuclear and extended family, regardless of mother or fathers side, builds a cohesive unit of strength emotionally, sometimes financially and offers support that is not commonly expected outside of family ties. National polls and summaries do not generally include information in regards to socio-economic classes, instead Denmarks citizens are divided up into 5 social layers. These social layers consist of subcategories within each layer. (HOG, ERLING, and HELLE JOHANNESSEN) The first social layer consists of corporate owners, employees of the educational system and anyone that has over 50 workers. The second social layer involves academically professional owners of businesses, agricultural owners with at least 4 employees and corporate owners that have over 6 workers. The third social layer includes small business owners, individuals with employment that calls for special skills and agricultural owners with a limit of 3 workers. The fourth social layer is made up of employees containing academic training, owners of small plots of land and experienced employees. The fifth social layer consists of employees with no special skills or experience. (HOG, ERLING, and HELLE JOHANNESSEN) Denmark, as a social organization, is very tolerant of other peoples ways of perceiving life and is considered to be outgoing and well-educated. Danes are very accepting of homosexual marriage and equality of the sexes. Denmark was the first European nation to allow for legal gay marriages within its borders offering homosexuals the majority of rights granted to straight married couples. Danes are very conscientious when it comes to preserving a clean, toxic-free environment. (Bendure, Glenda, and Ned Friary) A recent news article summarizes a protest put on by Greenpeace activists at the Environment Ministry in Denmark. This article was used for this research paper, because Danes are very involved in environmental policies in regards to keeping the planet as clean and sustainable as possible. The article was personally interesting, because Denmark is one of the most environmentally conscious nations on the planet and I was curious to see how they react to the disposing of harmful waste products. The Greenpeace activists were protesting the transport of a poisonous pollutant called HCB from an Australian company named Orica. The Kommunekemi in Nyborg, Denmark is one of a small number of companies in the world that is able to incinerate the hazardous carcinogen, HCB. The Greenpeace activists argued that hazardous waste materials should be incinerated closer to the point to which they are processed. This is just one of many examples of the Danish cultures desire for a cleaner and greener pl anet. (Greenpeace Goes Aloft to Protest Transport from Down Under) Danes are also known to love their most famous amusement park, Tivoli. This amusement park is located in Copenhagen and is the most popular attraction in Denmark. The park was built in 1914 and maintains a dà ©cor and cuisine that is based on the historical, traditional Danish culture of the time the park first opened. Some Danes pay the parks entry cost just to eat at a few of the thirty-seven restaurants within the park. The park has roller coasters, games, gardens and various amusements and entertainment. (Copenhagen, Denmark) Danish people are in love with the concept of social gatherings combined with eating and the two almost always go hand-in-hand. It is customary for a Danish household to always have tea, chocolates, pastries and cheese just in case guests arrive unexpectedly. Their meals often consist of three or more courses and it is considered a crime to oneself to not savor and take time to enjoy ones meal. Danes love rich, whole foods of which often include broiled or marinated fish, thick and creamy cheeses, hearty breads, substantial gravies and delectable deserts. Hot tea is often served with milk and honey and it is customary to leave the last bit of food in a main communal dish when eating. This is a symbolic action of politeness to show that nobody is selfish or rushed during the meal. The Danish culture is known for being one of the happiest cultures on earth. They are generally friendly, warm and open to communication with strangers. Recently, Denmark has incorporated many American concepts, products, stores and fast-food conveniences into their societal organization. Unfortunately, they are also gaining a few of the health problems that are associated with the introduction of American culture into their nation. However, despite the Danes cultural borrowing, they still have a strong sense of uniqueness through a proud society that shows compassion for its citizens and welcomes visitors. (Waldron, Julie)

The Rain Horse By Ted Hughes Essay -- English Literature

The Rain Horse By Ted Hughes 1. Before he sees the horse, the narrator is feeling confused and angry; "anger against himself for blundering into this mud-trap" As you can see from another word in the sentence, 'blundering', the narrator's anger against himself has made him clumsy, and 'blundering' is a very clumsy word. At this point, the narrator is feeling confused because he cannot decide whether to go round a longer journey, or take a shortcut through a farm. It seems as though he has a bad history with the farmer, because he talks of being called a trespasser; "or shouted at as a trespasser deterred him" 2. The sense of fear and mystery surrounding the horse is given because the writer uses many similes to describe it; "running on its toes like a cat, like a dog up to no good like a nightmarish leopard" Because the horse is far away from him, he can only give a description of its appearance, and he can not know any more, this is what gives the horse a sense of mystery and wonder. 3.

Harmonic Elimination

336 IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 22, NO. 1, JANUARY 2007 Modulation-Based Harmonic Elimination Jason R. Wells, Member, IEEE, Xin Geng, Student Member, IEEE, Patrick L. Chapman, Senior Member, IEEE, Philip T. Krein, Fellow, IEEE, and Brett M. Nee, Student Member, IEEE Abstract—A modulation-based method for generating pulse waveforms with selective harmonic elimination is proposed. Harmonic elimination, traditionally digital, is shown to be achievable by comparison of a sine wave with modi? d triangle carrier. The method can be used to calculate easily and quickly the desired waveform without solution of coupled transcendental equations. Index Terms—Pulsewidth modulation (PWM), selective harmonic elimination (SHE). I. INTRODUCTION S ELECTIVE harmonic elimination (SHE) is a long-established method of generating pulsewidth modulation (PWM) with low baseband distortion [1]–[6]. Originally, it was useful mainly for inverters with naturally low switching frequency due to high power level or slow switching devices.Conventional sine-triangle PWM essentially eliminates baseband harmonics for frequency ratios of about 10:1 or greater [7], so it is arguable that SHE is unnecessary. However, recently SHE has received new attention for several reasons. First, digital implementation has become common. Second, it has been shown that there are many solutions to the SHE problem that were previously unknown [8]. Each solution has different frequency content above the baseband, which provides options for ? attening the high-frequency spectrum for noise suppression or optimizing ef? iency. Third, some applications, despite the availability of high-speed switches, have low switching-to-fundamental ratios. One example is high-speed motor drives, useful for reducing mass in applications like electric vehicles [9]. SHE is normally a two-step digital process. First, the switching angles are calculated of? ine, for several depths of modulation, by sol ving many nonlinear equations simultaneously. Second, these angles are stored in a look-up table to be read in real time. Much prior work has focused on the ? st step because of its computational dif? culty. One possibility is to replace the Fourier series formulation with another orthonormal set based on Walsh functions [10]–[12]. The resulting equations are more tractable due to the similarities between the rectangular Walsh function and the desired waveform. Another orthonormal set approach based on block-pulse functions is presented in [13]. In [14]–[20], it is observed that Manuscript received August 2, 2006; revised September 11, 2006.This work was supported by the Grainger Center for Electric Machines and Electromechanics, the Motorola Center for Communication, the National Science Foundation under Contract NSF 02-24829, the Electric Power Networks Ef? ciency, and the Security (EPNES) Program in cooperation with the Of? ce of Naval Research.

Digital Object Identi? er 10. 1109/TPEL. 2006. 888910 the switching angles obtained traditionally can be represented as regular-sampled PWM where two phase-shifted modulating waves and a â€Å"pulse position modulation† technique achieve near-ideal elimination. Another approximate method is posed by [21] where mirror surplus harmonics are used. This involves solving multilevel elimination by considering reduced harmonic elimination waveforms in each switching level.In [22], a general-harmonic-families elimination concept simpli? es a transcendental system to an algebraic functional problem by zeroing entire harmonic fami lies. Faster and more complete methods have also been researched. In [23], an optimal PWM problem is solved by converting to a single univariate polynomial using Newton identities, Pade approximation theory, and symmetric function properties, which . If a few can be solved with algorithms that scale as O solutions are desired, prediction of initial guess values allows rapid convergence of Newton iteration [24].Genetic algorithms can be used to speed the solution [25], [26]. An approach that guarantees all solutions ? t a narrowly posed SHE problem transforms to a multivariate polynomial system [27]–[30] through trigonometric identities [31] and solves with resultant polynomial theory. Another approach [32]–[34] that obtains all solutions to a narrowly-posed problem uses homotopy and continuation theory. Reference [35] points out the exponentially growing nature of the problem and proposes the â€Å"simulated annealing† method as a way to rapidly design the wavef orm for optimizing distortion and switching loss.Another optimization-based approach is given in [36] and [37], where harmonics are minimized through an objective function to obtain good overall harmonic performance. There have been several multilevel and approximate real-time methods proposed; these are beyond the scope here but discussed brie? y in [38]. This manuscript proposes an alternative real-time SHE method based on modulation. A modi? ed triangle carrier is identi? ed that is compared to an ordinary sine wave. In place of the conventional of? ine solution of switching angles, the process simpli? s to generation and comparison of the carrier and sine modulation, which can be done in minimal time without convergence or precision concerns. The method does not require an initial guess. In contrast to other SHE methods, the method does not restrict the switching frequency to an integer multiple of the fundamental. The underlying idea was proposed in [39] but has been re? ned he re to identify speci? c carrier requirements that exactly eliminate harmonics and improve performance in deeper modulation. The method involves a function of modulation depth that is derived from simulation and curve ? ting. In this respect, it has some similarity to [15] and [16], in which approximate switching angles are calculated and ? tted to simple functions for cases of both low-( 0. 8 p. u. ) and high-modulation depth. It is interesting that the proposed approach connects modulation to a harmonic elimination process.

Direct calculation of the phase modulation function at various modulation depths with ? rst through 177th harmonics controlled. i? cation is common in other PWM work, as in switching frequency ra ndomization intended to reduce high-frequency components. A detailed review is outside the scope, but one discussion is given in [40]. The proposed technique is not a variation of random-frequency carriers. Instead, the carrier waveform is modi? ed in a speci? c and deterministic way to bring about a certain effect. The proposed method is readily implemented in real time.The switching signals themselves can be generated by analog comparison, while the modi? ed carrier is generated with fast digital calculation and digital-to-analog conversion. Hardware demonstration is provided here. An approximate, low-cost implementation based on present-day hardware is given in [41], but further re? nement is needed for precise elimination. II. SIGNAL DEFINITIONS AND SIMULATED RESULTS Consider a quasi-triangular waveform to be used as the carrier signal in a PWM implementation. In principle, the frequency and phase can be modulated.To represent this, consider a triangular carrier function written as (1) where is the base switching frequency, is a phase-mod0, (1) reulation signal, and is a static phase shift. For duces to an ordinary triangle wave based on conventional quadrant de? nitions of the inverse cosine function. The modulating where signal will be represented as is the depth of modulation. The pulsewidth-modulated signal, , is 1 if and 1, otherwise. 2 In [39], a phase modulation function is considered, where is the desired output fundamental fre, but dequency. This was shown to approach SHE at low 0. . To determine a better phase-modulagrades above tion function, the pattern of switching angles that occurs was investigated. Fig. 1 shows the phase modulation values needed for various with harmonics 1–109 conversus angle trolled. Fig. 2 shows the same with harmonics 1–177 controlled. Many other sets of controlled harmonics were tested with similar results. The pattern looks much like a shockwave pattern that can be modeled with the Bessel–Fubini e quation from nonlinear acoustics [42] (2) where is a Bessel function of the ? rst kind. The natural is in? ity in principle, but for calculation purposes number 15 or higher is usually suf? cient, as discussed below. The and have been determined by curve functions ? tting as (3) 1. and (4), shown at the bottom of the page, where 0 Fig. 3 shows a closeup view of a PWM waveform generated as in (2). Nineteen harmonics are with a carrier that uses 0. 95. The waveform is compared controlled with a (high) to one generated with conventional elimination by numerical solution of nonlinear equations. As can be seen, the switching edges match well. Fig. 4 shows a full-period time waveform and a magnitude 11.With spectrum [fast Fourier transform (FFT)] for this switching frequency ratio, the method eliminates harmonics two through ten (even harmonics are zero by symmetry). The 2 and the modulation depth carrier phase shift is set to 1. The spectrum con? rms the desired elimination. is 0. This v alue Fig. 5 shows the same study except with also achieves satisfactory baseband performance, but with a different pulse pattern. The pattern provides slight differences in higher-order harmonics. For example, the 11th and 13th harto . monics vary 2%–3% in magnitude as is varied from (4) 338IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 22, NO. 1, JANUARY 2007 Fig. 3.

Pulse waveform p, message signal m, and magnitude of pulse waveform spectrum for ! =! 11, m 1, and ‘ =2. = = = In these cases, all baseband harmonics are eliminated. In three-phase systems, triplen harmonics may cancel in the currents automatically if neutral current does not ? w. Therefore it is not always necessary to eliminate them by design in the SHE pro cess. Modulation-based harmonic elimination excluding triplen harmonics is similar in many respects to the case here. However, the phase-modulation functions resemble piecewise polynomials rather than the shockwave form of Figs. 1 and 2. This is discussed in detail in [38]. The speed of calculating these waveforms is dictated by , the number of terms to keep in the series (2), and , the number of discrete points used to approximate the waveforms. A personal computer (1. 86-GHz Intel M Processor with 1. -GB RAM) running MATLAB on Windows XP was used to carry out the calculations. First, a modi? ed triangle wave was ap100 000 points per cycle, the modulation proximated with 1, and a frequency ratio of 19 was used. depth was set to was varied from ? ve to 35. Over this range, the The number quality of solution was acceptable and the average calculation time varied from 0. 327 to 0. 915 s. Next, the same conditions 35 and was varied from 10 000 were used with except to 200 000. The aver age calculation time varied almost linearly from 0. 149 to 1. 78 s with no signi? cant difference in the resulting spectrum.Finally, with held constant at 100 000, the frequency ratio was varied from seven to 51. The average calculation time was consistently near 0. 92 s. This is expected since the number of harmonics eliminated has no scaling effect in (2). However, for larger frequency ratios, larger may be needed for precision. In summary, it is recommended that be set to at least 1,000 the frequency ratio and set to at least 15. In any case, with present-day personal computers the solution can be calculated in less than 1 s (typically) without iteration, divergence, or need for an initial estimate, and reduced versions can be computed in less than 200 ms.Notice that this time interval need not cause trouble with real-time implementations. The carrier only needs to be recomputed with the modulation signal changes. In applications such as uninterruptible supplies, this is infreque nt. In motor-drive applications, a response time of 200 ms to a command change may be acceptable as is. Alternatively, a look-up table can store some of the relevant terms to speed up the process dramatically. Dedicated DSP Please de? ne DSPalgorithms will be much faster than PC computations based on MATLAB. III. EXPERIMENTAL EXAMPLES To show that the proposed technique satisfactorily eliminates harmonics, the modi? d carrier was programmed into a function generator. The output provided a carrier signal in a conventional sine-triangle process. Three examples are shown below to reveal a range of interesting conditions. Fig. 6 shows the resulting waveforms for a high-depth case 0, and 0. 95. The with nineteen harmonics eliminated, and are shown at frequency ratio is 21:1. The signals the top, followed by the PWM waveform and the FFT spectrum. From the spectrum it can be seen that the desired harmonic-free baseband spectrum is achieved. In the next example, the phase 2.The unexpected r esult was that the spectrum shift is was insensitive to , as shown in comparison to Fig. 7. The desired spectrum occurs despite the difference in carriers. The resulting PWM waveforms at various values of may not offer obvious advantages, but it is noteworthy that they are not the same as conventionally computed SHE waveforms and would not be achievable with conventional SHE solution techniques. As another example, it is shown that the carrier base fre, need not be an odd multiple of . In Fig. 8, the frequency, IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 22, NO. 1, JANUARY 2007 339 Fig. .

IV. CONCLUSION A method for calculating and implementing SHE switching angles was proposed and demonstrated.The method is based on modulation rather than solution of nonlinear equations or numerical optimization. The approach is based on a modi? ed carrier waveform that can be calculated based on concise functions requiring only depth of modulation as input. It rapidly calculates the desired switching waveforms while avoiding iteration and initial estimates. Calculation time is insensitive to the switching frequency ratio so elimination of many harmonics is straightforward. It is conceivable the technique could be realized with low-cost microcontrollers for real-time implementation.Once the carrier is computed, a conventional carrier-modulator comparison process produces switching instants in real time.
