Basis history of oppression, diversity and struggle of human rights in Coursework

Basis history of oppression, diversity and struggle of human rights in the U.S - Coursework Example Thirdly powerless refers to a state where there is imbalance of power whereby the oppressed group becomes the recipients of oppressive authority. The fourth form of oppression according to Young (1990, p49) is cultural imperialism, which entails the â€Å"universalization† or establishment of the culture and experiences of the dominant group in the society as the model or norm from which other groups should adopt. The cultures or traditions of the oppressed group are not indentified and are regarded as deviant because they do not conform to those of the dominant group. Finally, violence is the fifth form of oppression and Young (1990, 54) defines it as â€Å"unprovoked physical attacks of a person and /or their properties†. Latina women and people with disabilities experience the Young’s five forms of oppression in the United States with varying degrees. Latinos have unique history of oppression in the United States society .The women of Latino descent experience oppression for being members of a minority group in the country as well as within their distinct ethnic groups (Gonzales, 2000). Historically, people from Latin America have been source of cheap labor for the Americans, working for low wages in American industries and plantations. Although the Latinos benefit from getting their subsistence, the rewards of their labor profit the American owners. Use of Latinos cheap labor amounts to oppression according to Young (1990). Marginalization of Latinos is a prevalent occurrence especially in regions with high population of these minority groups. Marginalization is manifested by exclusion of the community in making crucial economic, political and social policies in the United States. Consequent ly, Latinos suffer from higher unemployment rates, poverty and illiteracy levels than the majority group. For long period, Latinos have been

Lies, Lies, Lies Essay Example for Free

Lies, Lies, Lies Essay The white lie is an age old embellishment that has different reasons for being told. When it is all said and done a white lie is still a lie. A lie told with perfectly good intentions. A lie told to spare someone’s feelings. A lie about something trivial, which will have few consequences if you’re caught. A minor, polite, or harmless lie, a white lie is considered harmless as opposed to a black lie which is evil. Anything that is not accurate is a lie. There are a million reasons to tell a social white lie. Being nice leads to lying to prevent hurting someone’s feelings and it is commonly used by all. The baby in a stroller and the mother looks up, it is natural to say â€Å"What a cute baby† It could be the ugliest baby; yet the need to make a charitable response leads to a lie. Or Men say â€Å"I love you too† a white lie commonly told by men. The boss has on a dress that looks horrible, â€Å"What a beautiful dress† would someone tell the boss her dress is ugly. These are just examples of how we get caught up and we feel the need to say something positive instead of telling the truth. Lying begins early, if you observe children most know how to fib at the age of 4. By 6 they stop fibbing and begin lying. Watching and observing their parents, they gain insight in imitating their parents in the art of deception, they are told how to lie to relatives about gifts they may not like, and thus starts the white lies. The proverbial lie is used in our society to make small talk, to have someone show favor, when we greet someone, and we often lie to ourselves, â€Å"I am going to get up each day and walk.† I’ve said it, and I know I want to but I don’t. Salesman says anything you want to hear to sell a product. The doorman says â€Å"Have a good day†, no tip, doesn’t care if you even live another day almost every white lie is because of what a person wants to achieve with that white lie. It is almost second nature to living how we deceive, the Landlord I mailed that check yesterday. I lost my debt card can’t make the payment today will call as soon as I get my replacement! *I can’t come in today I have diarrhea; you’re going to the movie matinee. Researchers have been studying deception for decades, trying to figure out why we tell lies. It seems that our capacity for deceit appears nearly endless. That doesn’t mean we just tell a lie to hear it there is a purpose for the madness. Still lying is generally regarded as immoral and distasteful, â€Å"No one likes being lied to,† says former FBI agent and lying expert Joe Navarro. â€Å"We use lies to grease the wheels of social discourse.† Says University of Massachusetts psychologist Robert Feldman.

Pros and Cons of Globalization and Localization Essay -- Globalization

Growing up in the United States, we have been lucky enough to have been blessed with a stable economy. There has always been the extreme feeling of complacency and stability that comes with being a very large, internationally respected country. Strangely enough, America does not only reap the benefits of globalization, but it also basks in the glory of localization. We have, as a country, experienced much success both internationally and domestically. For example, without our international businesses booming the way they are, our country would suffer from a great economical loss. "One third of the growth of our economy comes from exports." (The New York Times, 9/15/98) On the other hand, localization brings the citizens a great sense of nationalism. It feels good to see something with a made in America tag on it, and it also feels great to know that we are not totally dependent on other countries. On more of an international level, "there is no question that freer capital flows have brought tremendous benefits to the global economy, as well as perils. Some places, like Hong Kong, have opened themselves to capital flows without restriction and are examples of the prosperity that free movements of capital can reap." (The New York Times, 9/20/98) On the other hand, the Malaysian economy, so far, has witnessed some short-term success with a localized view on their economy. Malaysia bans "most investments from being taken out of the country within the first year." (The New York Times, 9/20/98) Many countries are planning to try to follow in their footsteps. There are so many pros and cons, or costs and benefits, of both globalization and localization. For the United States, being a largely international economic country, "trading... ...with those changes are the adaptations that each country and each citizen of each country must go through. Whether or not the government chooses to act globally or domestically, there needs to be a conscience effort to make the best of what is offered. From each of these economic views, there are fundamental gains and fundamental losses. Neither is a more correct way. It is just what works for a country on a whole. There are all different levels of economic complexity that goes along with these two schools of thought. One has to do with the citizens, another with the government, and another with the world. The best thing for a country to do is to give up as little as it can while its political systems and economy conform to what it wants. To do so, one must weigh the costs and benefits of each, choosing what will be the best in the present and in the future.

Nineteen Eighty Four †Dystopian Society Essay

In the novel â€Å"Nineteen Eighty-Four† George Orwell created the dystopian society of Oceania, where the government has complete control of the language used by citizens. Aside from individuals of lower social class called the â€Å"Proles,† the â€Å"Party† constantly watches everyone. In an attempt to eliminate any chances of rebellion against the Party, they created the new language of â€Å"Newspeak. † Newspeak eliminates any controversial words along with all synonyms, antonyms and verbs. By doing this, the government has gained the power of meaning. Syme, a specialist in Newspeak tells the main character Winston exactly what control Newspeak has allowed the Party to have. â€Å"Don’t you see the whole aim of Newspeak is the narrow the range of thought? In the end we shall all make thoughtcrime literally impossible, because there will be no words in which to express it. † (Orwell 54). Along with that, the Party also has complete control of written language by altering history related documents to match the history that is in favor of this political power. The altering of these documents is what happens to be Winston’s job. While at work Winston pondered the power of being able to control the past, coming to a startling realization. As written by the narrator of the novel, â€Å"the past, he reflected had not only been altered, it had actually been destroyed. For how could you establish even the most obvious fact when there existed no record outside your own memory? † (Orwell 36). On top of being historically mislead, citizens are restricted of express any thought of their own or any way to voice against the Party. When you no truthful record for the past, the past doesn’t exist. When you have no words to associate with a meaning, the meaning behind the word then vanishes just like the political history of Oceania. For these reasons, a society with government restricted verbal and written language is one that proves to be dystopian.

Postoperative CABG depression Essay

1. Why did Japan Airlines Development Company decide to develop a hotel company in the mid-1980s? It was developed to strengthen the company’s marketing and financial position. JAL is known for its aggressive global marketing and application of new technology in hotel operations, the company is determined to establish a worldwide network of hotels comparable in number to Hilton, Sheraton, and inter-Continental. 2. Why did Nikko Hotels International choose the Essex House in New York City as its first property in the United States? The chose the Essex hotel to be the first hotel Nikko to be a springboard for Nikko’s future growth. Nikko’s executives believed that if they could do well with the Essex house in the competitive NY market, then they would do well in other markets within the United States. 3. Can you describe the cultural diversity of the management team at the Essex House? When Nikko took over the Essex house they invited all of the on site Marriott managers and staff to stay with the new company, since they were being replaced by Nikko to manage the Essex. Six managers decided to stay and they were all a very culturally diverse group. A Austrian, Irish, Lebanese, Japanese, and a manager from North America. This group of executive managers represented a highly diverse cultural group. 4. What was the purpose of the executive retreat? The purpose of the retreat was to create a Nikko mission statement 5. When did Miura join the managers at the executive retreat? The retreat was held in May 1981 in Ithaca in upstate New York. Miura who was the president of the company, showed up at the retreat after the group sessions and attended the presentations and started to comment on them. 6. How did he annoy the non-Japanese managers during their presentations? Miura annoyed the non Japanese executives, because they felt that his comments were not allowing them to contribute to their mission statement. They felt as though he was testing them and already had a mission statement and was wasting their time. 7. Why was Miura shocked to hear complaints from his managers? What did he do after he regained control of himself? Miura was shocked to hear the sharp criticisms because he felt that the executive managers were his subordinates. He didn’t understand why everyone was so upset with his comments. 8. What happened the next day? The next day, Miura tried to start over and began his speech to the executive team in a frank and all humble manner. He spoke about the global strategic development by JAL, and explained why the Nikko company had come to the united states. He shared with this team his 27 years of experience with JAL, and appealed to the group for cooperation. After his speech, he joined the team as a working participant to develop the Nikko mission statement. 9. What is the mission statement for Nikko Hotels? Dedicated employees, attentive service, quality facilities, together in harmony 10. Can you explain what cultural blunder Miura committed during the executive retreat and how he ridged the cultural gap and brought the team together? Miura committed a cultural blunder when first speaking at the retreat. The group had not known much about this man and his culture. He gave critical feedback to his subordinates during the presentation. Instead of talking to the team and sharing his background, he spoke down to them and did not originally share about himself. The best thing that he did was go home and do his â€Å"homework† so that he could better learn how to communicate with this group of culturally diverse people. He came back the next day with a better outlook and attitude and treated the group as a team and worked together instead working away from one another. Comments: If cultural diversity can be managed effectively, there is potential to use diverse workforce if it will benefits the organization. I think that multiculturalism can be directly linked to the success of the organization.It helps to promote minority friendly reputation among potential employeesVarious cultural societies help customers to achieve that with a variety of people.The ability to manage cultural diversity increases adaptability and flexibility of an organization to environmental changes. Whatever the country of origin of the guest at Hotel Nikko, it sounds as though with the diverse group of employees that have kept, that there is a good chance that staff will be able to speak their native language and understand what may cause offense. In my opinion, language capability is a tool that helps attract new business as well as service customers once they have arrived. I found it very interesting the way that Miura was perceived at the retreat. Being a nurse, I see this type of cultural â€Å"blunder†, a lot when working with patients and their families. You really have to be culturally sensitive when working with people of other cultures. Many mannerisms can be taken the wrong way if you are not familiar with other cultures and their personalities. I think that Miura meant well, but of course because of his culture he was unable to communicate effectively to his employees. They didn’t feel that he was on their side working with them at first. I really admire that Miura went back to his hotel and thought about what he would say to the people at the retreat the following day. I  really like that he decided to share his history and where he came from and where his vision is. I think that is so important when first meeting with people, especially a boss. I recently had a manager for our unit that never did share anything about herself. She was bold, aggressive and didn’t always communicate effectively. We grew to dislike her, and knew nothing about her which gave us no appreciation or understanding of where she was coming from sometimes. After working with her for 4 years, she decided to leave and seek another job at a different hospital. It was then, in her goodbye email that she unloaded and shared with us her life. Me and my other coworkers then began to have a little understanding and perspective on why she would do the things that she did and why she had such a un approachable demeanor. If only she had shared with us over the years, our unit may have run a lot more effectively. I like that Nikko hotels are so culturally diverse with their employees. Its multicultural work force is helping achieve great respect and popularity by creating an international environment within the hotel which makes guests from around the world feel at home.

Free Essays on Female Recidivisim

Gender Inequality The influence of society’s gender biased roles can be traced back to the moment of human birth. Immediately sex roles are defined and can be divided into stereotypes. At a very young age the child is exposed to what it means to be either a boy or a girl. There are the gender specific color associations of blue for male and pink for female. There are gender distinct male names such as John, Paul and Tim while female names include Mary, Lisa and Elizabeth. As the child grows, even play toys have their gender differentiated purposes such as cars, balls and tools for males while the females are given dolls, doll houses and tea sets (Adolescence 1997). A child’s earliest exposure to what it means to be male or female comes from the parents. There is an expectant behavior from the child and as children grow and develop the gender stereotypes that are continuously reinforced are further perpetuated throughout childhood and into adolescence. Thus the stereotypes become firmly implanted into beliefs and also as part of the child’s self-concept. The theoretical perspective of gender polarization is the foundation for these gender specific divisions of male and female roles in society. â€Å"Gender polarization defines mutually exclusive scripts for being male and female and any deviation from these scripts as unnatural†. (Lenses of Gender pp. 80-87). Traditional male roles in society includes the economic provider, family patriarch, community educator, voter, property owner and sports athlete. In contrast the female traditional roles included the child bearer, home keeper and subordinate to the males. As females continue to cross over the boundary into the traditional male roles, then each act is considered to be abnormal or the act itself to be unnatural. The perceived invasion of females into the male role causes men to protect its once dominant social role. Feminists argue that â€Å"no j...

Say What You Mean

Say What You Mean Say What You Mean Say What You Mean By Michael One of the most influential teachers of writing was Rudolf Flesch. I encountered him through an out-of-print book called On Business Communications, formerly titled Say What You Mean. Only later did I discover that he also wrote the 1955 educational critique Why Johnny Cant Read. His other titles include The Art of Plain Talk, The Art of Readable Writing, How to Write Better you get the idea. Flesch practiced what he preached: everything Ive read by him was superbly readable, even entertaining. Throughout most of On Business Communications, Flesch fights a battle against business and government communication that is formal for its own sake, neglecting the very purpose of communication, which is to say something. We all tend to write the way we think were expected to write, instead of pondering the best way to meet our readers needs. Flesch fought the common belief that official writing must be boring or stuffy, or else nobody will respect it. The documents of the U.S. Social Security Administration became a little easier to read after they hired Rudolf Flesch as a consultant. Flesch was a pioneer of readability testing. His simple Flesch–Kincaid Readability Tests are still used by educators to assign appropriate grade levels to reading material. The more syllables in a word, the more words in a sentence, the more difficult an article is to read. You can test the readability of any web page against Fleschs formula at Juicy Studio. But readability goes beyond mathematical calculations. How a reader feels about an article influences whether he or she will understand it or even finish reading it. When people open a new book or magazine, they may subconsciously scan it to see if its reader-friendly. Do they see lots of periods? That means short sentences. Lots of white space? That may mean short paragraphs. Do they see exclamation points and question marks? That means that it isnt straight, routine exposition. A potential reader may subconsciously look for personal pronouns. That actually increases readability, because it suggests that the author is writing about people, and people are interesting. Does the book or article contain vocabulary that you wouldnt expect to see, such as the word puppy in a chemistry article? That suggests that it contains metaphors and analogies, which are easier to understand, and not just chemical formulas. Does it contain specific nouns at all? Seeing the word Weimaraner in an article gives me more hope of an interesting read than dog or animal. Flesch taught the importance of personality and personal connection in writing. A reader is not merely a customer, he or she is a human being like yourself, looking for reassurance and connection. We all want to hear, Im sorry about that, I know what you mean, I found the answer to your question, I solved your problem, and Thank you so much! Sentences like those appear all too rarely in business and government writing, and Flesch said there is no good reason why they shouldnt. Flesch had a special gift for helping to simplify legal language and theres a special reason for that. In one instance, he condensed a paragraph of gobbledy-gook into something like, These people have owed you $10,000 for two months. If they dont pay by next month, I think you should sue. Many clients might worry whether writing so simple can still be legally binding. Not to worry. Before he came to the United States, Rudolf Flesch was a lawyer in Vienna.

Associations of Diet and Lifestyle with Hyperlipidemia for Middle-Aged Assignment

Associations of Diet and Lifestyle with Hyperlipidemia for Middle-Aged and Elderly Persons among the Guangxi Bai Ku Yao and Han Populations - Assignment Example Since the study is focused Guangxi Bai Ku Yao and Han Populations, all other populations apart from ones used as control samples will be excluded from the study. Information on demography, dietary intake, and lifestyle factors was collected by standard questionnaires. Blood pressure, height, weight, waist circumference, and serum lipid levels were measured, and body mass index (BMI) was calculated as weight (kg) divided by height (m) squared. Data will be collected depending on various methods that will be used in the study to collect data. Since study will be conducted within certain period of time, there will be specific timing of measurements collected, depended variable like diet and lifestyle, and independent variables like middle-aged and elderly people. There will also be control variables as discussed above. In this study, people between the age of 25 and 65 (both male and female) were used in this study. This study will be focused on two clans Bai Ku Yao and Han. Their lifestyle and eating habits will also be used in this study.

Divide and Conquer Assignment Example | Topics and Well Written Essays - 750 words

Divide and Conquer - Assignment Example Moreover, the study helps in developing a better understanding of the political processes and the relationship of different actors with each other and their impact on the system as a whole (Cunningham, 2011). The author argues that the study will explain in detail the concept of divide and conquer and divide and concede. He also argues that the logic behind them helps in determining the frequency, effects, and size of concessions. The author finally argues that the research will show how internal divisions affect the concessions (Cunningham, 2011). The researcher focuses on the divided and unitary characteristics of self determination movements and argues that it is important to study these characteristics as they help us in understanding which self determination movements have more control and which methods are more effective. The author argues that the study will help in getting insight on how the states respond to divided and unitary self determination movements and highlight the difference between them (Cunningham, 2011). The author argues that the governments are less likely to make concessions to divided self determination movements as the movements are weak and thus the threat is not as strong. The author uses the example of Yasser Arafat who failed to deliver to Palestinians after negotiations (Cunningham, 2011). The logic behind the concept is that if the government feels that the concessions will not settle the dispute, they are not likely to make settlements with divided self determination movements. The divide and concede logic argues that groups that are in favor of independence respond well to limited concessions. The state makes use of concessions in the bargaining process in favor of the moderates within the movement giving rise to the competition between different factions in the movement. It is different from divide

ESCAPING SALEM Essay Example | Topics and Well Written Essays - 250 words

ESCAPING SALEM - Essay Example In an attempt to find what she is suffering from – mind, it being an era that witchcraft was common -- Kate accuses others of bewitching her. Two women were finally put on trial. The book Escaping Salem takes the reader through the Connecticut court room. Witchcraft in a court room is more dramatic than one would ever imagine. The town’s people are scared of the act and its practice in the township, and this is a view that the judges are quick to point out to. Witchcraft poses a great danger to the society. However, how would Branch prove that the women actually were behind her ailments? Her accusations come from the fact that some evil spirit informed her about it. How would she prove this and how would she prove that the spirit were indeed factual? Escaping Salem offers an insightful revelation of life style in the early seventeenth century America. In addition, it offers proof of the existence of the white magic, an issue that has strongly been argued upon. The only pitfall that Godbeer‘s work seems to pose is the use of some of the photos that are manipulated. The photos are helpful in offering illustration and adding to the maps; the selected bibliography seems to provide some proof too. However, the use of the photos is overrated. This is a historical book and the images ought not to appear to be fictitious. In retrospect, the book is a must read for any undergraduate student of American History or Political Science. The insights it offers are indeed factual and one would relate them to the life of that

The Human Relations Movement Term Paper Example | Topics and Well Written Essays - 2000 words

The Human Relations Movement - Term Paper Example Response Scientific management concept gave birth to the field of management about a century ago with pioneering work performed by Fredrick W Taylor during 1900s. The concept of management has, ever since, evolved and developed into a completely new framework that is based on quite contrasting factors described in scientific management, referred to as the human relations movement, after pioneering work of Elton May and colleagues through the Hawthorne experiments. While scientific management levied greater emphasis on the employer and the business, contemporary management levies higher significance on employees. However, both management concepts are focused on improving and growing business and reducing costs and wastage. Management specialists regard scientific management or Taylorism as the villain and the Human Relations Movement as the hero of present times. This discourse evaluates this comparison in lieu of current organizational challenges. In the process, it also evaluates va rious situations that continue to apply scientific management concepts and how these concepts continue to save organizations. At the same time, application concepts from the human relations movement are also analyzed.

Economics - Essay Example Therefore, wages are considered a good indicator in employing people and expanding the business. Labor regulations like the ‘minimum wage’ affects the price signals in the market by disturbing the supply and demand. The differences between the supply and demand for labor could harm many people with the use of a minimum wage. This is true in the sense that increasing the minimum wage could result to an increase in the prices of goods. High prices of goods will eventually decrease the demand for the specific goods. Thus, people would tend to look for an alternative sources of similar item in order to maximize the value of their money. The SRAS curve would shift to the left; it means a decrease in the number of goods sold as prices of goods increases. (See Figure 1 – Aggregate Supply and Demand when Minimum Wage is Increased on page 4) Increasing the minimum wage could affect the U.S. international competitiveness and labor freedom. People who support an increase in the minimum wage insist that it would help the poor and less-skilled workers. However, the government intervention on this matter has an adverse effect in the market place. The increase in the minimum wage could affect the supply and demand curve leading to a less efficient in the allocation of labor. Thus, resulting to an increase in unemployment rate. (See Figure II – Supply and Demand of Labor When an Increase in Minimum Wage is Implemented on page 4) Each time the equilibrium real wage is not equal to the market-clearing real wage, the real wage becomes too high. In this case, some businesses would be forced not to hire additional manpower. For companies that are experiencing a bad business performance combined with a bad economic situation, some of these firms may choose to implement mass lay-offs or simply declare bankruptcy or closure. It simply proves that increasing the real wage too high would result to an involuntary unemployment. Determining

The Human Relations Movement Term Paper Example | Topics and Well Written Essays - 2000 words

The Human Relations Movement - Term Paper Example Response Scientific management concept gave birth to the field of management about a century ago with pioneering work performed by Fredrick W Taylor during 1900s. The concept of management has, ever since, evolved and developed into a completely new framework that is based on quite contrasting factors described in scientific management, referred to as the human relations movement, after pioneering work of Elton May and colleagues through the Hawthorne experiments. While scientific management levied greater emphasis on the employer and the business, contemporary management levies higher significance on employees. However, both management concepts are focused on improving and growing business and reducing costs and wastage. Management specialists regard scientific management or Taylorism as the villain and the Human Relations Movement as the hero of present times. This discourse evaluates this comparison in lieu of current organizational challenges. In the process, it also evaluates va rious situations that continue to apply scientific management concepts and how these concepts continue to save organizations. At the same time, application concepts from the human relations movement are also analyzed. Scientific management was indeed first science applied to management in order to help the employer reap maximum benefits from his/her employers’ efforts. ...

This is important to note that was conducted in a span of month month so as to ensure that each and every staff was interviewed. Motivation of employee is one key issue that is facing every organization. It is the responsibility of every leader in an organisation to ensure employees are motivated and also create a very conducive environment for them in the workplace (Koontz 1993). Though an employee may be capable to perform his/her job description without motivation every human being needs to feel a little bit of appreciation as this will spur inner urge to work well in an organisation. It is this role of a leader that he has to ensure that his workforce is motivated and if not he should identify a strategy on how to make them moretivated as this will enable him achieve his organisational goals(Marginson 1986). Motivation cannot be understated as it is always a key ingredient to help an organisation in achieving its goals. Issuinig of instructions that are well and clealy friendly (Marginson 1986). A manager first has to understand he has the right team and after it is when he should ensure that the team is motivated so as to keep the focus on objective goals.The role to motivate employees depends on very different dimesions and they cannot be for one department like the human resource but the whole organisation.Itis thus important to understand all humans have different needs and may be motivated in different ways but one of the most important task is to ensure it is done (Alous 2002). Strong needs in directing and satisfying latent needs in employees harness them in a manner that is functional for the organization. For motivation to be successfully implemented the factors that trigger motivation should be identified and analysed properly.The goal here is to identify the causes of motivation and not the

Firstmover Advantage Essay Example for Free

Firstmover Advantage Essay What, exactly, are first-mover advantages? Under what conditions do they arise, and by what specific mechanisms? Do first-movers make aboveaverage profits? And when is it in a firm’s interest to pursue first-mover opportunities, as opposed to allowing rivals to make the pioneering investments? In this paper we examine these and other related questions. We categorize the mechanisms that confer advantages and disadvantages on first-mover firms, and critically assess the relevant theoretical and empirical literature. The recent burgeoning of theoretical work in industrial economics provides a rich set of models that help make our understanding of first-mover advantages more precise. There is also a growing body of empirical literature on order-of-entry effects. Our aim is to begin to provide a more detailed mapping of mechanisms and outcomes, to serve as a guide for future research. We define first-mover advantages in terms of the ability of pioneering firms to earn positive economic profits (i. e. , profits in excess of the cost of capital). First-mover advantages arise endogenously within a multi-stage process, as illustrated in Figure 1. In the first stage, some asymmetry is generated, enabling one particular firm to gain a head start over rivals. This first-mover opportunity may occur because the firm posesses some unique resources or foresight, or simply because of luck. Once this asymmetry is generated there are a variety of mechanisms that may enable the firm to exploit its position; these mechanisms enhance the magnitude or durability (or both) of first-mover profits. Our discussion is organized as follows. We first consider theoretical models and empirical evidence on three general categories in which first-mover advantage can be attained: leadership in product and process technology, preemption of assets, and development of buyer switching costs. We then examine potential disadvantages of first-mover firms (or conversely, relative advantages enjoyed by late-mover rivals). These include free-rider problems and a tendency toward inertia or sluggish response by established incumbents. The next section addresses a series of basic conceptual issues. These include the endogenous nature of first-mover opportunities, and various definitional and measurement questions. We conclude with an assessment of opportunities for additional research, and a summary of managerial implications. 1 MECHANISMS LEADING TO FIRST-MOVER ADVANTAGES First-mover advantages arise from three primary sources: (1) technological leadership, (2) preemption of assets, and (3) buyer switching costs. Within each category there are a number of specific mechanisms. 1 In this section we survey the existing theoretical and empirical literature on these three general categories of first-mover advantages. The theoretical models surveyed in this section assume the existence of some initial asymmetry among competitors that can be exploited by the first-mover firm. This intial asymmetry is critical; without it first-mover. advantages do not arise. Later in the paper we consider ways in which this asymmetry may come about. Technological Leadership First-movers can gain advantage through sustainable leadership in technology. Two basic mechanisms are considered in the literature: (1) advantages derived from the â€Å"learning† or â€Å"experience† curve, where costs fall with Cumulative output, and (2) success in patent or RD races, where advances in product or process technology are a function of RD expenditures. Learning curve In the standard learning-curve model, unit production costs fall with cumulative output. This generates a sustainable cost advantage for the early entrant if learning can be kept proprietary and the firm can maintain leadership in market share. This argument was popularized by the Boston Consulting Group during the 1970s and has had a considerable influence on the strategic management field. In a seminal theoretical paper, Spence (1981) demonstrated that when learning can be kept proprietary, the learning curve can generate substantial barriers to entry. Fewer than a handful of firms may be able to compete profitably. 2 However, despite high seller concentration there are incentives for vigorous competition. Firms that do enter may initially sell below cost Rumelt (1987) refers to these as â€Å"isolating mechanisms,† since they protect â€Å"entrepreneurial rents† from imitative competition. 2 1n a related setting where learning depends on accumulated investment rather than output, Gilbert and Harris (1981) show that a first-mover will preempt in the construction of new plants over multiple generations. 1 2 in an effort to accumulate greater experience, and thereby gain a long-term cost advantage. Such vigorous competition sharply reduces profits. Empirical evidence supporting such learning-based preemption is given by Ghemawat (1984) in the case of DuPont’s development of an innovative process for titanium dioxide, and by Porter (1981) who discusses Proctor and Gamble’s sustained advantage in disposable diapers in the US. Similarly, Shaw and Shaw (1984) argue that late entrants into European synthetic fiber markets failed to gain significant market shares or low cost positions, and many ultimately exited. Learning-based advantages are also evident in the case of Lincoln Electric Company (Fast, 1975); the firm’s early market entry with superior patented products, coupled with a distinctive managerial system promoting continued cost reduction in an evolutionary technological environment, has enabled the company to sustain remarkably high profitability. Inter-firm diffusion of technology, which diminishes first-mover advantages derived from the learning curve, is emphasized in theoretical papers by Ghemawat and Spence (1985) and Lieberman (1987c). It is now generally recognized that diffusion occurs rapidly in most industries, and learning-based advantages are less widespread than was commonly believed in the 1970s. Mechanisms for diffusion include workforce mobility, research publication, informal technical communication, â€Å"reverse engineering,† plant tours, etc. For a sample of firms in ten industries, Mansfield (1985) found that process technology leaks more slowly than product technology, but competitors typically gain access to detailed information on both products and processes within a year of development. Lieberman (1982, 1987b) shows that diffusion of process technology enabled late entry into a sample of forty chemical product industries, despite strong learning curve effects at the industry level. R~Dand patents When technological advantage is largely a function of RD expenditures, pioneers can gain advantage if technology can be patented or maintained as trade secrets. This has been formalized in the theoretical economics literature in the form of RD or patent races where advantages are often enjoyed by the first-mover firm. Gilbert and Newberry (1982) were the first to develop a model of preemptive patenting, in which a firm with an early head-start in research exploits its lead to deter rivals from entering the patent race. Subsequent papers by Reinganum (1983), Fudenberg, et 3 al. (1983) and others showed that that preemption by the leader depends on assumptions regarding the stochastic nature of the RD process and whether it is possible for followers to â€Å"leapfrog† ahead of the incumbent. One general defect of this patent race literature is that all returns are assumed to go exclusively to the winner of the race. As an empirical matter, such patent races seem to be important in only a few industries, such as pharmaceuticals. In most industries, patents confer only weak protection, are easy to â€Å"invent around,† or have transitory value given the pace of technological change. For a sample of 48 patented product innovations in pharmaceuticals, chemicals and electrical products, Mansfield et al. (1981) found that on average, imitators could duplicate patented innovations for about 65% of the innovators cost; imitation was fairly rapid, with 60% of the patented innovations imitated within four years. Imitation appeared relatively more costly in the pharmaceutical industry, where immitators must go through the same regulatory approval procedures as the innovating firm. Levin et al. (1984) found wide inter-industry variation in the cost and time required for imitation. They also found inter-industry differences in appropriability mechanisms, with lead-time and learning curve advantages relatively important in many industries, and patents important in few. In a study using the PIMS data base, Robinson (1988) found that pioneer firms benefit from patents or trade secrets to a significantly greater extent than followers (29% vs. 13%). However, he also found that patents accounted for only a small proportion of the perceived quality advantages enjoyed by pioneers. Several case studies have examined the role of patents in sustaining firstmover advantages. Bresnahan (1985) discusses Xerox’s use of patents as an entry barrier. In addition to key patents on the basic Xerography process, Xerox patented a thicket of alternative technologies which defended the firm from entry until challengers used anti-trust actions to force compulsory licensing. Bright (1949) argues that GE’s long-term dominance of the electric lamp industry was initially derived from control of the basic Edison patent, and later maintained through the accumulation of hundreds of minor patents on the lamp and associated equipment. RD and innovation need not be limited to physical hardware; firms also make improvements in managerial systems and may invent new organizational forms. Organizational innovation is often slow to diffuse, and hence may convey more durable first-mover advantage than product or process innovation (Teece, 1980). Chandler (1977) describes managerial innovations that enabled producers to exploit newly-available scale economies in 4 manufacturing and distribution in the late 19th century. Many of these firms—e. g. , American Tobacco, Campbell Soup, Quaker Oats, Proctor and  Gamble—still retain dominant positions in their industries. Preemption of Scarce Assets The first-mover firm may be able to gain advantage by preempting rivals in the acquisition of scarce assets. Here, the first-mover gains advantage by controffing assets that already exist, rather than those created by the firm through development of new technology. Such assets may be physical resources or other process inputs. Alternatively, the assets may relate to positioning in â€Å"space,† including geographic space, product space, shelf space, etc. Preemption of input factors II the first-mover firm has superior information, it may be able to purchase assets at market prices below those that will prevail later in the evolution of the market. Such assets include natural resource deposits and prime retailing or manufacturing locations. Here, the returns garnered by the first-mover are pure economic rents. 3 A first-mover with superior information can (in principle) collect all such rents earned on non-mobile assets such as resource deposits and real estate. 4 The firm may also be able to appropriate some of the rents that accrue to potentially mobile assets such as employees, suppliers and distributors. The firm can collect such rents if these factors are bound to the firm by switching costs, so that their mobility is restricted. One empirical study of first-mover advantages in controlling natural resources is Main (1955). Main argues that the concentration of high-grade nickel deposits in a single geographic area made it possible for the first company in the area to secure rights to virtually the entire supply, and thus dominate world production for decades. The basic argument is sta-ndard economic analysis, and can be traced back to Ricardo’s analysis of rents captured by landowners (first-movers) in the market for wheat in 19th century England. 4 Note that with complete markets, a first-mover with superior information need not actually own or control such assets to capture economic rents. Hirshleifer (1971) argues that if futures markets exist, the firm can simply assume forward market positions that exploit its superior information. 3 5 Preemption of locations in geographic and product characteristics space First-movers may also be able to deter entry through strategies of spatial preemption. In many markets there is â€Å"room† for only a limited number of profitable firms; the first-mover can often select the most attractive niches and may be able to take strategic actions that limit the amount of space available for subsequent entrants. Preemptable â€Å"space† can be interpreted broadly to include not only geographic space, but also shelf space and â€Å"product characteristics space† (i. e. , niches for product differentiation). The theory of spatial preemption is developed in papers by Prescott and Vissher (1977), Schmalensee (1978), Rao and Ruttenberg (1979) and Eaton and Lipsey (1979, 1981). The basic argument is that the first-mover can establish positions in geographic or product space such that latecomers find it unprofitable to occupy the interstices. If the market is growing, new niches are filled by incumbents before new entry becomes profitable. 5 Entry is repelled through the threat of price warfare, which is more intense when firms are positioned more closely. Incumbent commitment is provided through sunk investment costs. 6 The empirical evidence suggests that successful preemption through geographic space packing is rare. In their study of the cement industry, Johnson and Parkman (1983) found no evidence of successful geographic preemption even though structural characteristics of the industry suggest that such strategies would be likely. In a study of local newspaper markets, Glazer (1985) found no difference in survival rates between first- and second-mover firms. One explanation for these findings is that all firms in cement and newspaper markets have similar technologies and entry opportunities, so preemptive competition for preferred sites drives profits to zero. In other words, there were no initial asymmetries in timing or information to be exploited. One counter-example illustrating effective geographic preemption is a case study of the Wal-Mart discount retailing firm (Ghemawat, 1986b). Wal-Mart targeted small southern towns located in contiguous areas that competitors initially found unprofitable to serve. By coupling spatial preemption at the retail level with an. extremely efficient distribution network, the firm has been able to defend its position and earn sustained high profits. Schmalensee (1978) developed his model of product space preemption in lncumbents fill these niches in order to sustain monopoly profits at nearby locations; these profits may be dissipated if new entry occurs. 6 judd (1985) argues that sunk costs are not sufficient; exit costs are required as well. 5 6 the context of a lawsuit brought by the Federal Trade Commission against the three major US breakfast cereal companies. The FTC alleged that these firms had sustained their high profit rates through a strategy of tacit collusion in preempting supermarket shelf space and product differentiation niches. Although the lawsuit was dismissed, the cereal firms have continued to sustain exceptionally high profit rates. 7 Robinson and Fornell (1985) found that new consumer product pioneers initially held product quality superiority over imitators, and eventually developed advantages in the form of a broader product line. Thus, there is some evidence that pioneers try to reinforce their early lead by filling product differentiation niches. Preemptive investment in plant and equipment Another way in which an established first-mover can deter entry is through pre-emptive investment in plant and equipment. Here, the enlarged capacity of the incumbent serves as a commitment to maintain greater output following entry, with price cuts threatened to make entrants unprofitable. In these models, the incumbent may successfully deter new entry, as in Spence (1977), Dixit (1980), Gilbert and Harris (1981) and Eaton and Ware (1987). Alternatively, pre-emptive investment by the pioneer may simply deter the growth of smaller entrants, as in Spence (1979) and Fudenberg and Tirole (1983). These investment tactics do not seem to be particularly important in practice. Gilbert (1986) argues that most industries lack the cost structure required for preemptive investment to prove effective. Lieberman (1987a) shows that preemptive investment by incumbents was seldom successful in deterring entry into chemical product industries. One exception was magnesium, where Dow Chemical maintained a near monopoly position for several decades, based largely on investments (threatened or actual) in plant capacity (Lieberman, 1983). The role of scale economies is intentionally de-emphasized in the abovementioned models of preemptive investment. 8 When scale economies are large, first-mover advantages are typically enhanced, with the limiting case being that of natural monopoly. However, outside of public utilities, scale 7 8 0f course, these profits may be derived from sources other than spatial preemption. have also ignored the possibility that network externalities may enhance the po- sition of the first-mover firm. These externalities arise if there are incentives for interconnection or compatibility among users. (See, for example, Farrell and Saloner (1986) and Katz and Shapiro (1986). ) 7 economies approaching the natural monopoly level are seldom observed in US manufacturing industries. 9 In a theoretical treatment, Schmalensee (1981) shows that in most realistic industry settings, scale economies provide only minor entry barriers and hence potential for enhanced profits. Switching Costs and Buyer Choice Under Uncertainty Switching costs First-mover advantages may also arise from buyer switching costs. With switching costs, late entrants must invest extra resources to attract customers away from the first-mover firm. Several types of switching costs can arise. First, switching costs can stem from initial transactions costs or investments that the buyer makes in adapting to the seller’s product. These include the time and resources spent in qualifying a new supplier, the cost of ancillary products such as software for a new computer, and the time, disruption, and financial burdens of training employees. A second category of switching costs arises due to supplier-specific learning by the buyer. Over time, the buyer adapts to characteristics of the product and its supplier and thus finds it costly to change over to another brand (Wernerfelt, 1988). For example, nurses become accustomed to the intravenous solution delivery systems of a given supplier and are reluctant to switch (Porter, 1980). A third type of switching cost is contractual switching cost that may be intentionally created by the seller. Airline frequent flyer programs fit in this category (Klemperer, 1986). Theoretical models of market equilibrium with buyer switching costs include Klemperer (1986) and Wernerfelt (1986, 1988). Switching costs typically enhance the value of market share obtained early in the evolution of a new market. Thus, they provide a rationale for pursuit of market share. However, first-movers with large market shares do not necessarily earn high profits; early competition for share can dissipate profits. And under some conditions the inertia of an incumbent with a large customer base can make this firm vulnerable to late entrants, who prove to be relatively more profitable (Klemperer, 1986). For example, see Weiss (1976). This finding applies to manufacturing operations only; greater scale economies may arise in distribution and advertising. Also, many retailing markets are geographically fragmented, leading to the possibility of spatial preemption of the sort described earlier. Such preemption requires the presence of some scale economies in the form of fixed costs. 9 8 Buyer choice under uncertainty A related theoretical literature (e. g. , Schmalensee, 1982) deals with the imperfect information of buyers regarding product quality. In such a context, buyers may rationally stick with the first brand they encounter that performs the job satisfactorily. Brand loyalty of this sort may be particularly strong for low-cost â€Å"convenience goods† where the benefits of finding a superior brand are seldom great enough to justify the additional search costs that must be incurred (Porter, 1976). In such an environment, early-mover firms may be able to establish a reputation for quality that can be transferred to additional products through umbrella branding and other tactics (Wernerfelt, 1987). Similar arguments derived from the psychology literature suggest that the first product introduced receives disproportionate attention in the consumer’s mind. Late entrants must have a truly superior product, or else advertise more frequently (or more creatively) than the incumbent in order to be noticed by the consumer. In a laboratory study using consumer products, Carpenter and Nakamoto (1986) found that order-of-entry influences the formation of consumer preferences. If the pioneer is able to achieve significant consumer trial, it can define the attributes that are perceived as important within a product category. Pioneers such as Coca-Cola and Kleenex have become prototypical, occupying a unique position in the consumer’s mind. Pioneers’ large market shares tend to persist because perceptions and preferences, once formed, are difficult to alter. More traditional marketing studies confirm the existence of such perceptual effects. In a study of two types of prescription pharmaceuticals—oral diuretics and antianginals—Bond and Lean (1977) found that physicians ignored â€Å"me-too† products, even if offered at lower prices and with substantial marketing support. ’ ° Montgomery (1975) found that a product’s newness was one of the two key variables necessary to gain acceptance onto supermarket shelves. These imperfect information effects should be greater for individual consumers than corporate buyers, since the latter’s larger purchase volume justifies greater investment in information acquisition activities)-~ Using the 0ne explanation of these findings is that physicians are price insensitive because they do not actually pay the prescription costs. However, the Carpenter and Nakamoto (1986) experiments found that more typical consumers are also unwilling to switch to objectively similar â€Å"me-too† brands, even at substantially lower prices. 11 Moreover, switching costs in industrial markets often dissipate over time as the buy~r becomes more knowledgeable about competing products (Cady, 1985). 10 9 PIMS data base, Robinson (1988) and Robinson and Fornell (1985) found that pioneers had larger market shares than followers in both consumer and industrial markets, but the effect was much greater for consumer goods: order of entry explained 18% of the variance in market share in consumer goods markets, but only 8% in industrial markets. For a sample of 129 consumer packaged goods, Urban et al. (1986) found a strong inverse relation between order-of-entry and market share. Brand positions remain remarkably durable in many consumer markets. Ries and Trout (1986) noted that of twenty-five leading brands in 1923, twenty were still in first place some sixty years later. Davidson (1976) found that two-thirds of the pioneers in eighteen United Kingdom grocery product categories developed since 1945 retained their market leadership through the mid- 1970s. FIRST-MOVER DISADVANTAGES The above-mentioned mechanisms that benefit the first-mover may be counterbalanced by various disadvantages. These first-mover disadvantages are, in effect, advantages enjoyed by late mover firms. Late movers may benefit from: (1) the ability to â€Å"free ride† on first-mover investments, (2) resolution of technological and market uncertainty, (3) technological discontinuities that provide â€Å"gateways† for new entry, and (4) various types of â€Å"incumbent inertia† that make it difficult for the incumbent to adapt to environmental change. These phenomena can reduce, or even completely negate, the net advantage of the incumbent derived from the mechanisms considered previously. Free-Rider Effects Late movers may be able to â€Å"free ride† on a pioneering firm’s investments in a number of areas including RD, buyer education, and infrastructure development. As mentioned previously, imitation costs are lower than innovation costs in most industries. However, innovators enjoy an initial period of monopoly that is not available to imitator firms. Nevertheless, the ability of follower firms to free ride reduces the magnitude and durability of the pioneer’s profits, and hence its incentive to make early investments. The theoretical literature has focused largely on the implications of freerider effects in the form of information spillovers in RD (Spence, 1984; Baldwin Childs, 1969), and learning-based productivity improvement 10 (Ghemawat and Spence, 1985; Lieberman, 1987c). As mentioned previously, empirical studies document a high rate of inter-firm diffusion of technology in most industries. Guasch and Weiss (1980) assess free-rider effects operating in the labor market. They give a theoretical argument that late-mover firms may be able to exploit employee screening performed by early entrants, and thus acquire skilled labor at lower cost. This is on top of the fact that early entrants may invest in employee training, with benefits enjoyed by later entrants who may be able to hire away the trained personnel. Teece (1986a, 1986b) argues that the magnitude of free-rider effects depends in part on the ownership of assets that are complementary or specialized† with the underlying innovation. For example, EMI developed the first CT scanner but lost in the marketplace because the firm lacked a technology infrastructure and marketing base in the medical field; Pilkington, by comparison, was able to profit handsomely from its pioneering float glass process because of the firm’s ability to draw upon relevant assets and experience in the glass industry. In other instances late-mover firms have proven successful largely because they were able to exploit existing assets in areas such as marketing, distribution, and customer reputation—e. g. , IBM in personal computers and Matsushita in VCRs (Schnaars, 1986). Resolution of Technological or Market Uncertainty Late movers can gain an edge through resolution of market or technological uncertainty. 12 Wernerfelt and Karnani (1987) consider the effects of uncertainty on the desirability of early versus late market entry. They argue that early entry is more attractive when firms can influence the way that uncertainty is resolved. Firm size may also matter—they suggest that large firms may be better equipped to wait for resolution of uncertainty, or to hedge by maintaining a more flexible portfolio of investments. In many new product markets, uncertainty is resolved over time through the emergence of a â€Å"dominant design. † The Model T Ford and the DC-3 are examples of such designs in the automotive and aircraft industries. After emergence of such a design, competition often shifts to price, thereby con12 A related point is that a late-mover may be able to take advantage of the firstmover’s mistakes. For example, when Toyota was first planning to enter the US market it interviewed owners of Volkswagons, the leading small car at that time. Information on what owners liked and disliked about the VW was incorporated in the design process for the new Toyota. 11 veyin. g greater advantage on firms possessing skills in low-cost manufacturing (Teece, 1986b). Shifts in Technology or Customer Needs. Schumpeter (1961) conceived of technological progress as a process of â€Å"creative destruction† in which existing products are superceded by the innovations of new firms. New entrants exploit technological discontinuities to displace existing incumbents. Empirical studies which consider these technological discontinuities or â€Å"gateways† for new entry include Yip (1982), and Bevan (1974). Foster (1986) gives practical advice on how such discontinuities can be exploited by entrants, who might be defined as â€Å"first-movers† into the next technological phase. Sch. erer (1980, p.438) provides a list of innovative entrants who revolutionized existing industries with new products and processes. He also cites numerous examples of dominant incumbents that proved slow innovators but aggressive followers (p. 431). Since the replacement technology often appears while the old technology is still growing, it may be difficult for an incumbent to percieve the threat and take adequate preventative steps. Cooper and Schendel (1976) provide several examples, such as the failure of steam locomotive manufacturers to respond to the invention of diesel. Foster (1986) cites American Viscose’s failure to recognize the potential of polyester as a replacement for rayon, and Transitron’s inattention to silicon as a substitute for germanium in semiconductor fabrication. This perceptual failure problem is closely related to that of â€Å"incumbent inertia† considered below. Customer needs are also dynamic, creating opportunities for later entrants unless the first mover is alert and able to respond. Docutel, as the pioneer, had virtually 100% of the automatic teller machine market up to late 1974. Over the next four years, its market share declined to less than 10% under the onslaught of Honeywell, IBM and Burroughs, all of whom offered total system solutions to customers’ emerging needs for electronic funds transfer (Abell, 1978). Incumbent Inertia Vulnerability of the first-mover is often enhanced by problems of â€Å"incumbent inertia. † Such inertia can have several root causes: (1) the firm may be locked-in to a specific set of fixed assets, (2) the firm may be reluctant to cannibalize its existing product lines, or (3) the firm may become organi-12 zationally inflexible. These factors inhibit the ability of the firm to respond to environmental change or competitive threats. Incumbent inertia is often a rational, profit-maximizing response, even though it may lead to organizational decline. For example, Tang (1988) presents a model that rationalizes the decisions of most U. S. steel producers to continue investing in open hearth furnace technology during the late 1950’s and early 1960’s even though it had become clear that basic oxygen furnaces were superior. A firm with heavy sunk costs in fixed plant or marketing channels that ultimately prove sub-optimal may find it rational to â€Å"harvest† these investments rather than attempt to transform itself radically. 13 MacMillan (1983) suggests that in the rapidly-changing environment of health care, old health care systems may currently be harvesting from their initial investments in locations and personnel. The appropriate choice between adaptation and harvesting depends on how costly it is to convert the firm’s existing assets to alternative uses. And as we consider below, there have been numerous instances where organizational inertia has led firms to continue investing in their existing asset base well beyond the point where such investments could be economically justified. Much of the literature on cannibalization-avoidance refers to the case of RD. Arrow (1962) was the first to lay out the theoretical argument that an incumbent monopolist is less likely to innovate than a new entrant, since innovation destroys rents on the firm’s existing products. More recent theoretical work along these lines include Reinganum (1983) and Ghemawat (1986a). Bresnahan (1985) argues that Xerox exhibited such behavior following the expiration ofits patent-enforced monopoly—Xerox lagged in certain types of innovations and was sluggish to cut prices, given the firm’s large fleet of rental machines in the field. Brock (1975) and Ghemawat (1986a) make similar arguments regarding the innovative responses of IBM in computers and ATT in PBX’s. However, Connor (1988) shows that under a broad range of conditions, the incumbent’s optimal strategy is to develop an improved product but delay market introduction until challenged by the appearance of a rival product. From an organizational theory perspective, Hannan and Freeman (1984) outline factors that limit adaptive response by incumbents.

Nanotechnology In Architecture

Nanotechnology In Architecture Historically and geographically human have lived in extremely varied technology or environment and have had to adapt to comfort habitats and thus the architects have had to manage the ideal of design as well as incorporate the evolutionary technology. A technology has evolved to a level where it is just too complex. Sometimes satisfying the need of the user and sometimes becoming too dangerous when the negative consequences are not taken care of. For example, the issues of the Large scales in architecture is one such matter which has been partially solved with the help of low cost materials, energy savingà ¢Ã¢â€š ¬Ã‚ ¦etc. The scientists have developed and are continuing to develop nanotechnology to help architects incorporate more artificial intelligence in construction. Nanotechnology is a combination of various fields of science like, Bio- technology, Chemistry, Physics, Bio-informatics, etc. There are three chief divisions in Nanotech: Nanoelectronics, Nanomaterials, and Nano-Biotechnology. Worldwide, there is much enthusiasm about nanotechnology as it has application in medicine, electronics, biomaterials, energy etc. It is observed that US, Japan, and Germany dominate the current RD effort in nanotechnology with a focus on they own expertise and needs (Hyd and spook, 2012). The use and control of the technology at an atomic or particle scale known as nanotechnology has started to have its impact like never before in materials of constructions and has immense futurist impact in architecture, this application of the nanotechnology and nanomaterials in architecture is NanoArchitecture. The nano world in technology is a real challenge for todays designers, it started with an understanding and control of the technology and materials on one billionth (10-9) scale. The understanding of these materials, its use in architecture to be profitable for users and its implication on the building (Construction) are some of the key aspect for inquiry in this dissertation. With the perfect solution of this dilemma, the Architects would not only know how big their task is but how it might lead to new ways of thinking architecture. After understanding the meaning and origin of this technology, we will study certain aspects that is a must in todays constructions and then we see the direction where this science is going, we will also look at the ways to incorporate these technologies in our architecture, therefore the question that will guide our research is how does nano (technology, materials, science, concept, form and function) become important to the level of influencing architects (designers). Nanotechnology is developed in the manner that it is active or passive, this repartition will lead us to a large study but our focus will rely on the relation passive active nanostructure and application of nanotechnology in a building design and construction. Passive nanotechnologies, such as nanocoatings, nanoparticles, and nanostructured materials, are already available. Second generation active nanostructures, for example, nanoelectro-mechanical systems, nanomachines, self-healing materials, and targeted chemicals, can evolve their properties, structure and/or state during their operation. This could increase nanotechnologys impacts and require new approaches for risk assessment. Active nanostructures are likely to have a different and increased profile of impacts (including benefits as well as potential risks) compared with passive nanotechnologies. RESEARCH QUESTION: How does nano (technology, materials, science, concept, form and function) becomes important to the level of influencing architects (designers). NEED IDENTIFICATION: Over the years the materials used in buildings (during construction, inside or outside finishes) has been of a large scale, the evolution today have brought into existence the materials on a microscopic scale with even more value to life and building. They can be metals, ceramics, polymers or composites. Known as nanomaterials, nanocomposites, and manufactured nanomaterials (MNMs), the method of making these materials begins at the molecular or atomic level, sometimes creating new products with extraordinary physical and chemical properties. For example, a carbon nanotube has strength of 150 times that of steel but is approximately six times lighter. Besides strength enhancement, properties can include self-cleaning, super hardness, electrical conductivity, antimicrobial superior thermal resistance and stability, non-flammability, lightweight, anti-corrosion, superior barrier, light emitting and low permeability, among others. Applications in the building industry include use as fire retardants, high performance insulation, protective coatings, equipment lubricants, structural integrity enhancement and monitoring, photovoltaic, stronger tensile cables, and self-cleaning or heat absorbing windows ( CFN, 2011 )à ¢Ã¢â€š ¬Ã‚ ¦ Using these materials which contain extraordinary application in the building can also bring amazing influences to the architect, designer or the design. Therefore apart from attempting to understand the transformation that the nanotechnology brings to our building there is a need to understand by students the uses of nanotechnology for creating better design. SCOPE: à ¢Ã¢â€š ¬Ã‚ ¢ A general understanding of nano especially toward architecture à ¢Ã¢â€š ¬Ã‚ ¢ Nanotechnology (materials) applications in buildings à ¢Ã¢â€š ¬Ã‚ ¢ Concept; form and function derived from nano LIMITATION: à ¢Ã¢â€š ¬Ã‚ ¢ The laboratories details of certain materials and nano applications in medical branches will not be part of our research. à ¢Ã¢â€š ¬Ã‚ ¢ This research dissertation will have some limitation in details like calculations, manufactures process, chemical components. à ¢Ã¢â€š ¬Ã‚ ¢ Thinking in more detail about how to use nanomaterials in a design context, a first consideration is simply to define what is being design?. But there is a lack of built case studies, so we will rely on existing, futurist, basic concept and reading materials. à ¢Ã¢â€š ¬Ã‚ ¢ Regarding the size of this matter nanotechnology, we will limit at the level where nanotech is active and very briefly talk about the passive Nanotechnology RESEARCH METHODOLOGY: N A N O A R C H I T E C T U R E PART O.

The reading of the applications in nanotechnology in todays constructions is more related to Green designers, this part of the design has an impact in the ecology and climate control therefore the green rated buildings has in fact a considerable amount of nanotechnology use in it. This leads us to refer to architects involved in green concepts or sustainability from LEED etc ( Ar Alex Nyembo Kalenga) and also we could make a visit studies on the actual certified Green building Rajiv Gandhi urja Bhavan at Vasan Kunj New Delhi Still in Construction. A list of questions has guided our study and survey interview in which the answers are include to our conclusion of this research: 1.

Fundamental Knowledge II.1.1. WHAT IS NANOTECHNOLOGY? A brick is the smallest building block in construction. Whatever you do, the strength of the building is limited to the strength of the brick. The brick itself is made of minute particles of clay bonded together. One has limited control over how the particle of clay forms. Each particle of clay in turn is formed from molecules joined together in a particular pattern dictated by the forces of nature. What happens if it is possible to arrange these molecules in a pattern that provides greater strength? You get stronger clay and a stronger brick. This results in a much thinner, but stronger wall. This technology of arranging molecules the way we want is a basis of nanotechnology. (Johnzactruba, 2011) A strict definition of nanotechnology characterizes it as the manipulation of a matter at the scale of one-billionth of a meter or smaller. The measurement of one-billionth of a meter is identified as one nanometer (nm) (Jeffrey H. Matsuura,1957). Nano, is a word which does not only mean billionth less but also leaves a billionth of question in mind, because of the complexity to understand its simplicity. It is a world hold by the scientist, chemist and physicians. Yes nanotechnology is a relatively recent development in scientific research but not new. The level of its study and diversity has involved touching now many sector of life and becoming more and more known by the public. The concept first was introduced by American physicist Richard P. Feynman (1918-1988). But it is noted that in the 10th centuries the 16th centuries the ruby-red color of many stained-glass windows from the medieval era was a consequence of embedded nanoscale metallic particles within the glass. There were no scientific understanding of these phenomena at the time, nor were there deliberate attempts to produce what we now know as nanomaterials. Early knowledge relied on craft-based trial and error to achieve effects we must keep in mind, however, that not all interesting color phenomena are a result of embedded nanomaterials ( Michael F. Ashby, 2009). The evolution of nanotechnology has been more or less in the domain of chemical, medicine and physics (technique) then it involved to the environment, energy, agriculture, communication and information because of some of its advantage and disadvantage in the society. The main tools used in nanotechnology are three main microscopes: Transmission Electron Microscope (TEM), Atomic Force Microscope (AFM), and Scanning Tunneling Microscope (STM). (Jamie Jackson, CIS 121) II.1.2. NANO PRODUCTS Use as gateways to build other nano products, Nanosensors can be chemical sensors or mechanical sensors. Amongst other applications they can be used: à ¢Ã¢â€š ¬Ã‚ ¢ To monitor physical parameters such as temperature, displacement and flow à ¢Ã¢â€š ¬Ã‚ ¢ As accelerometers in Microelectromechanical systems (MEMS) devices that can rapidly and remotely detect change in their surroundings like airbag sensors à ¢Ã¢â€š ¬Ã‚ ¢ For medical diagnostic purposes either as blood borne sensors or in lab-on-a-chip type devices à ¢Ã¢â€š ¬Ã‚ ¢ To detect various chemicals in gases for pollution monitoring à ¢Ã¢â€š ¬Ã‚ ¢ Sensors using carbon nanotube detection elements are capable of detecting a range of chemical vapors. These sensors work by reacting to the changes in the resistance of a carbon nanotube in the presence of a chemical vapor ( Hawks Perch Technical Writing, 2007). II.1.2.1. Nanotube Known as well as Carbon Nanotube (CNTs), it is a tube-shaped material or cylindrical nanostructure made of carbon, having a diameter of nanometer scale. Nanotubes form a tiny portion of the material(s) in some baseball bats, golf clubs, or car parts. Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (GPa). Since carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm3, its specific strength of up to 48,000 kNà ¢Ã¢â€š ¬Ã‚ ¢mà ¢Ã¢â€š ¬Ã‚ ¢kgà ¢Ã‹â€ Ã¢â‚¬â„¢1 is the best of known materials, compared to high-carbon steels 154 kNà ¢Ã¢â€š ¬Ã‚ ¢mà ¢Ã¢â€š ¬Ã‚ ¢kgà ¢Ã‹â€ Ã¢â‚¬â„¢1. Standard single-walled carbon nanotubes can withstand a pressure up to 24GPa without deformation. The bulk modulus of super hard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal) and can produce materials with toughness unmatched in the man-made and natural worlds. Because of the carbon nanotubes superior mechanical properties, many structures have been proposed ranging from everyday items like clothes and sports gear to combat jackets and space elevators. However, the space elevator will require further efforts in refining carbon nanotube technology, as the practical tensile strength of carbon nanotubes can still be greatly improved (Wikipedia, 2012). II.1.2.2. Nanocomposites The definition of nano-composite material has broadened significantly to encompass a large variety of systems such as one-dimensional, two-dimensional, three-dimensional and amorphous materials, made of distinctly dissimilar components and mixed at the nanometer scale (Kanatzidis, 2006). New materials with novel proprieties are generate rapidly through this field. The properties of nano-composite materials depend not only on the properties of their individual parents but also on their morphology and interfacial characteristics. Although nanoscale reinforcements (or nanofillers) of nanocomposites have different kinds of fillers such as nanofibers, nanowires, nanotubes and nanoparticles etc, their mechanical behaviors have some common features. As the figure shows a potential use of nanocomposites as multifunctional materials (Journal Club, 2008). AREA OF APPLICATION Such mechanical property improvements have resulted in major interest in nanocomposite materials in numerous automotive and general/industrial applications. These include potential for utilisation as mirror housings on various vehicle types, door handles, engine covers and intake manifolds and timing belt covers. More general applications currently being considered include usage as impellers and blades for vacuum cleaners, power tool housings, mower hoods and covers for portable electronic equipment such as mobile phones, pagers etc (Professor J.N. Hay, 2001). The inorganic components can be three-dimensional framework systems such as zeolites, two-dimensional layered materials such as clays, metal oxides, metal phosphates, chalcogenides, and even one-dimensional and zero-dimensional materials such as (Mo3Se3-)n chains and clusters. Experimental work has generally shown that virtually all types and classes of nanocomposite materials lead to new and improved properties when compared to their macrocomposite counterparts. Therefore, nanocomposites which combine new nanomaterials with more traditional ones such as steel, concrete, glass, and plastics, can be many times stronger than standard materials and promise new applications in many fields such as mechanically reinforced lightweight components, non-linear optics, battery cathodes and ionics, nano-wires, sensors and other systems. On the market there already a nanocomposite steel that is three times stronger than conventional steel. Before long, nano-reinforced glass might be used for both structure and enclosure. In the some student projects in the nanoSTUDIO at Ball State University, nanotube structural panels create transparent load-bearing curtain walls free of columns and beams, quantum dots make walls and ceilings light up or change color with the flip of a switch, and nanosensors in building components create smart environments that constantly adapt to their environment and users. II.1.3. TYPOLOGY M. C. Roco, one of the driving forces behind the NNI, has developed a more detailed typology of nanotechnologies. He identifies four generations of nanotechnologies: passive nanostructures, active nanostructures, systems of nanosystems and molecular nanosystems (J. Clarence, 2009) ( Fig04: For generation of nanotechnology development, Center for Responsible Nanotechnology ) Each generation of products is marked by the creation of commercial prototypes using systematic control of the respective phenomena and manufacturing processes. Products may also include components which correspond to different generations. Todays rudimentary capabilities of nanotechnology for systematic control and manufacture at the nanoscale are expected to evolve significantly in both complexity and the degree of integration by 2020. II.1.3.1 Passive to Active nanotechnology It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment. An active nanostructure changes or evolves its state during its operation, according to the National Science Foundations (2006) Active Nanostructures and Nanosystems grant solicitation. Passive: (steady function) nanostructures Behaviour: inert or reactive nanostructures which have stable behaviour and quasi -constant properties during their use. Potential risk: e.g. nanoparticles in cosmetics or food with large scale production and high exposure rates. Active: (evolving function nanostructures) Behaviour: the nanostructures properties are designed to change during operation so behaviour is variable and potentially unstable. Successive changes in state may occur (either intended or as an unforeseen reaction to the external environment). Potential risk: e.g. nanobiodevices in the human body; pesticides engineered to react to different conditions. Categories of active nanostructures are: à ¢Ã¢â€š ¬Ã‚ ¢ Remote actuated active nanostructures, such as light-actuated embedded sensors; à ¢Ã¢â€š ¬Ã‚ ¢ Environmentally responsive active nanostructures, such as responsive drug delivery; à ¢Ã¢â€š ¬Ã‚ ¢ Miniaturized active nanostructures, such as synthetic molecular motors and molecular machines; à ¢Ã¢â€š ¬Ã‚ ¢ Hybrid active nanostructures, or uncommon combinations of materials, such as silicon-organic ; à ¢Ã¢â€š ¬Ã‚ ¢ Transforming active nanostructures, such as self-healing materials. (M.C. Roco, 2004, 2007) Tour estimates the time it will take to commercialize each of these types as 0-5 years for passive nanotechnologies, 15-50 years or more for active nanotechnologies and 7-12 years for hybrids (J. Clarence, 2009) II.1.4. WHY ALL THE FUSS ABOUT NANOTECHNOLOGY? NANOTECHNOLOGY: THE SCIENCE CHANGING YOUR LIFE Penny Sarchet The advantages of using nanomaterials in construction are enormous. When you consider that 41 percent of all energy use in the United States is consumed by commercial and residential buildings, the potential benefits of energy-saving materials alone are vast (Dr. Pedro Alvarez of Rice University, 2010) and when we have to evaluate the energy used by buildings in the rest of the world the result will surly show that the use of the nanomaterials in buildings will be of an anxiety necessity. Nanotechnology thus has profound potential because it can free us from some traditional limits and offer us useful new capabilities. Nanotechnology can change some of the physical rules that have traditionally confined us. It can also free us from some of the limitations that have long been placed upon us by size ( Jeffrey H, 1957). The key is to understand the specific risks and implications of the product before it is widely used. This way we can ensure that nanotechnology evolves as a tool for sustainability rather than as an environmental liability (Dr. Pedro Alvarez of Rice University, 2010). Benefices and profit with the nanotechnology is now in the hand of everyone and architects are with no doubt going to shape this realm to another level. e.g.: Solera enables seamless integration of natural daylight into the design and function of buildings. Well daylighted spaces deliver substantial and measurable benefits to sustainability, energy efficiency and human performance. This series of products provide architects with solutions to solve the challenges traditionally associated with daylighting techniques including solar heat gain, cost, complexity and glare. Other materials such as brickà ¢Ã¢â€š ¬Ã‚ ¦ have already showed us the changes that it has done to the industries, life, designers, buildersà ¢Ã¢â€š ¬Ã‚ ¦ In the early days, paint was available in a limited variety of colors for you to choose. Now most of the paint shops have mixers that allow the users to choose the color they require. The manufacturers have to produce and stock only a few basic colors, reducing production and inventory costs at much greater satisfaction to the consumer. The future of nanotechnology will be the personal nano-factories, like the paint mixers, that allow you to produce any material that you require. The shops have to carry only stock in molecular form. Advances in nanotechnology are moving at an exponential rate. It will eventually encompass every field of human activity including energy. (Johnzactruba, 2011) Disadvantages of Nanotechnology: Safety hazards with nanomaterials, Some studies detected possible cancer-causing properties of carbon nanotubes, Some nanomaterials bounded with other materials or components (Jamie Jackson, CIS 121) II.1.5. RISK OF NANOTECHNOLOGY It is obvious to find out that except from the greatness and impressive opportunities that nanotechnology offers, the risks are associated with it as well. And these risk touch-up on Health, environment, Industryà ¢Ã¢â€š ¬Ã‚ ¦ Because of the size of the particles, nanomaterials may enter human and other living bodies and disrupt body-functions. Some nanoparticles may also be non-biodegradable thereby posing a new threat to the environment. Therefore it is crucial to examine and estimate the risk for regulating the production, use, consumption and disposal of these materials. (Hyd and spook, 2012). For example, Health effects of several insulating materials are a concern; 1. The fibers released from fiberglass insulation may be carcinogenic, and fiberglass insulation now requires cancer warning labels. 2. There are also claims that the fire retardant chemicals or respirable particles in cellulose insulation may be hazardous (Dr. George, 2007). The risk most talked about is the ability of nanotech carbon tubes to potentially cause asbestosis-type illnesses, (Mike Childs, 2012) Manufactured nanomaterials (MNMs); and nanocomposites are being considered for various uses in the construction and related infrastructure industries. To achieve environmentally responsible nanotechnology in construction, it is important to consider the lifecycle impacts of MNMs on the health of construction workers and dwellers, as well as unintended environmental effects at all stages of manufacturing, construction, use, demolition, and disposal. Emphasis in industries; In India, late industry participation has also begun in this area, and there is an emphasis on fostering public-private partnerships (PPP). Nonetheless government support to this sector remains crucial for three reasons: 1. Nanotechnology is a capital-intensive technology and is in an embryonic phase, thus industry would not be able to sustain the research effort needed for the establishment of scientific and technological infrastructure. 2. The state is required to define the regulatory framework. In 2010-11 this process was initiated. 3. The state ,particularly in the developing country context, can set the agenda and resist the tendency to uncritically follow international trends in research that do not address their developmental needs.

III.1. Environmental application Environmentally, Nanotechnology also has the potential to help our environment. Example: It controls pollution through source reduction. This is a method of eliminating toxic waste at its source, with the understanding that releasing the waste into the environment is the last resort. Source reduction can be achieved by cleaning up existing processes or by reducing consumption of resources where such consumption creates pollution. III.1.1. Insulation The impact of the improvement of insulation reductions is counted by billions of pounds annually. Ref table (Fig06: Potential sources of EU CO2 emission reductions ) Nanoscale materials hold great promise as insulators because of their extremely high surface-to-volume ratio. This gives them the ability to trap still air within a material layer of minimal thickness (conventional insulating materials like fibreglass and polystyrene get their high insulating value less from the conductive properties of the materials themselves than from their ability to trap still air.) Insulating a nonmaterial may be sandwiched between rigid panels, applied as thin films, or painted on as coatings (Dr. George, 2007) Nanogel panels; Aerogel This material as an incredible ability and capacity such as strength, it can take its own load 2000 times reminding that it has only 5 percent solid and the rest is filled with air only an are also applicable on fabric architecture or structures. Because nanoporous aerogels can be sensitive to moisture, they are often marketed sandwiched between wall panels that repel moisture. Aerogel panels are available with up to 75 percent translucency, and their high air content means that a 9cm (3.5) thick aerogel panel can offer an R-value of R-28, a valu
