Engineering Methodologies and Their Origins

The importance of becoming a global engineer could not be more emphasized than in the distinct differences found between American and Japanese engineers. The Japanese engineering method is highly based on an interest in success of the group rather than the success of the individual, as seen in the American model of engineering. What makes this so interesting to me is the motivational reasons that allow these unique methods of engineering to be successful. This is very intriguing because, as an engineer, I have learned we are looking at a very narrow scope of how engineering should be conducted. The following excerpt (found in the recommended reading section) clearly shows the reality of the different engineering methodologies,


“Such treatment is unthinkable for Americans. Some years ago I used a film from JETRO entitles “A Day in the Life of a Japanese Engineer.” In several scences, the “engineer,” explicitly identified as a college graduate, is seen helping production line workers repair or adjust equiment. He gets dirty and greasy with the men on the production line. A few students always reacted to this by questioning the authenticity of the film. Assurances to the contrary notwithstanding, they found such scene hard to believe.
Their expectations of an “engineering education” may be gleaned from a float in the Picnic Day Parade at U.C.-Davis a few years ago. The float featured a Mercedes-Benz. Stage money $100 bills had been inserted in the wheel covers. Engineering students in formal dress stood around the Mercedez and sipped champagne (more likely Budweiser). A sign on the side of the float said “Hard Work and Study Pays.” Even allowing for a certain amount of tongue-in-cheek humor, no survey of attitudes is needed to confirm the U.S. student perception that engineering is a route to high pay, not the factory floor.”

After reading this excerpt I found this very intriguing from the perspective of an engineering major in college. This particular section is very similar to my own experiences as an engineering major myself. Before picking my intended major in high school I was told by my friends, family and counselor that becoming an engineer would mean job security, prestige and most importantly (to them) a generous paycheck. This system of choosing engineering shifts the emphasis and motivatian to the individual and selfish gains rather than taking into account the group or society as a whole. From my experiences in high school and at this university the example above couldn’t be more true. We, the students, are constantly bombarded with statistics and figures of how much money each engineering major makes after leaving college and how important it is to the purpose of our college degree and we have even discussed this in ES 410. I have yet to read anything about the importance of contributing to society as one of the dominant images of attaining an engineering degree (or any degree for that matter) as seen in many of the readings about Japanese engineers.


At first, I thought both methods of engineering would work in the U.S. or Japan but after further readings and consideration at this point in time or the near future I don’t think it would be a possibility. The Japanese and U.S. children as a whole, and I am speaking generally for the sake of argument, are raised with a different mentality which translates to this difference in engineering ideologies. Every week the ICEX group volunteers at a nearby elementary school to teach robotics to 2nd graders to attempt to gain an early interest in engineering and specifically robotics. The second purpose and probably the most important is to get females and minorities involved in engineering before stereotypes set in and negatively influence them to stray from engineering. Each week we bring simple robots for them to play with and then hold a competition at the end of the class period. What I noticed as an outsider looking in was when a child won they would announce that they in fact were the winner or boast about beating someone else. This may seem very normal but that is not the case from what I have seen in Japanese sports. At a very young age Japanese baseball players are taught to love the sport from a group perspective (including both teams). When the game is over both teams are cheered for equally and it is common to not even remember the final score because there isn’t an emphasis on “winning” in the sense of who scored the most. The emphasis is on the sport and teams as a group rather than on the individual. A statement from another article articulates this point further,


“... the most important virtue is the striving for mutual harmony. In the company, the Japanese do not consider themselves as individuals but rather as a tiny part of a whole social system and they are very eager to look after the professional and personal duties that lead to the fulfilment of a perfect harmony. Defining themselves as part of a group does not make them feel unimportant, but rather comfortable and sheltered.”

I believe these ideals are what transfer to the dominant images of what it means to be an engineer in the U.S. and Japan. By learning about the Japanese engineering methodology and hierarchy, it is clear there is more than one way to create a system of successful engineers.My biggest question after reading this article still remains: Why are we not learning about this in our engineering classes (from a curriculum perspective)?

Brazil - Worldwide Leader in Ethanol Production

Draft Abstract

The oil crisis of the late 1970s had an effect felt around the world, but while many other countries only temporarily turn their attention away from fossil fuels, Brazil pushed forward to become the global leader in ethanol production methods. Why did Brazil succeed in eliminating its dependence on foreign oil where other nations failed? My paper will focus on the history, development, and future of ethanol production in the country of Brazil and what steps it took to succeed where others failed. The uniquely Brazilian engineering culture will be showcased for its ability to adapt to changing demands from agricultural, energy, and global markets. The feasibility of transferring this technology to other appropriate developing countries will also be discussed.

Annotated Bibliography

1. Ethanol's mid-life crisis. (2010). Economist, 396(8698), 41-42.

The article focuses on Brazil's sugar industry. Sugar is the main crop in this country, which is the biggest exporter in the world. While sugar cane is very valuable, the needs of the market determine if it is used as a source of biomass energy products and biofuels, notably ethanol, or turned directly into sugar. Sugar now also forms the nucleus of a new agro-industrial and renewable-energy complex. Each segment of the sugar industry is asking for government regulation to promote its use. Government officials complain that when the world sugar price is high, the mills divert cane away from producing ethanol, which can make its price rise as well.

This struggle within the industry helps to showcase how the success of new technology or industry can be molded by government attention. For instance, Brazil's government requires petrol to be blended with three or four parts ethanol to one of petrol. This control of the market creates the demand necessary for such a large capital intensive industry to survive in a competitive, and often unfair, market. The United States and Europe do something similar while also placing a tariff on imported ethanol. While Brazil is more efficient at producing ethanol than any other country on Earth, the tariffs placed on each gallon of imported ethanol makes it more expensive than domestic ethanol.


2. Goldemberg, J. (2008). The brazilian biofuels industry.Biotechnology for Biofuels,1(6), 6.

This paper reviews the technological characteristics of ethanol as a fuel, the present 'status' of the ethanol Program in Brazil, the characteristics of ethanol as a renewable fuel, the future perspectives of the ethanol program in Brazil, and discusses the limitations on expansion for the industry. The author is very thorough in his citation of specific statistics with regards to each of these categories. This information will be helpful in analyzing the environmental, political, economic impacts of this technology. In the paper’s discussion of the future of ethanol, the mention of a reliance on first generation technologies as a limiting factor is enlightening. He mentioned the efficiency of sugarcane-to-ethanol production can still be increased through improvements such as TRS (total recoverable sugar), which has increased 1.5% per year in the period 1977–2004. These statistics will help to show how these technologies may be viable if transferred to other countries around the world.

3. REGALADO, A. (2010). Race for cellulosic fuels spurs brazilian research program.Science, 327(5968), 928-929

This article explains the importance of scientific discovery in the global race for ethanol production. The article stresses the importance of efficiency in production technologies. It mentions that Brazil’s sugar-cane based ethanol can be produced for half of what it costs in the United States, where ethanol is made from corn. The article discusses the huge amount of investments the U.S. and Europe are making in next-generation approaches, such as cellulosic ethanol production. Cellulosic ethanol is especially attractive because it can create energy from plant material normally considered waste. Brazil is also investing in this technology and has just built a demonstration plant of its own. Up til now, biofuel research has been practical or “applied research” based and many believe that is still the way to go, citing improvements to sugar extraction methods and the development of flex-fuel cares. Scientists claim that development of “next-generation” technologies can increase per-acre ethanol production by 40%, which would not be possible with first-generation technologies. To help realize these assumptions, Brazil is partnering with international companies such as Royal Dutch Shell and Monsanto to develop biofuel R&D.

4. Sovacool, B. (2010). The importance of open and closed styles of energy research.Social Studies of Science (Sage), 40(6), 903-930.

This paper explores the styles of research associated with wind turbines, ethanol and fuel cells in six countries. The concept of a ‘research style’ emphasizes that values and interests, along with deeper historical and cultural influences, shape research and get built into technology. Open research styles are epitomized by a broad inclusion of actors in the research process, participatory ownership of its results, cooperation among stakeholders and users, and experimentation and flexibility. Closed research styles are distinguished by limited access and ownership, competition among researchers, centralization of the research process and rigidity in dictating programme goals and preferences. The paper uses the concept of open and closed research styles to compare the experiences of Denmark, Brazil and China (open) with those in the USA, France and Norway (closed).

5. Qurashi, M and Hussain, Tajammul. (2005). Renewable Energy Technologies for Developing Countries Now and to 2023. Published by the Islamic Educational, Scientific and Cultural Organization

This is a very comprehensive document which encapsulates the need, importance, options and impact of renewable energy technologies in nearly all aspects of economic and environmental livelihood. The authors go on to establish policy options and alternatives both on the international and national stages. This book gives a thorough assessment of energy options and relates those with specific reference to various developing countries. The book assesses and analyzes the current energy situation of the world and provides logical and practical suggestions and recommendations for the future world energy assessment and policy. This will be invaluable to comparing the transferability of ethanol and biomass technology from Brazil to other countries around the world. It will also serve to give suggestions on other types of technologies might be appropriate to deal with the energy needs of developing countries.

6. Sandalow, David. (May 2006). Ethanol: Lesson from Brazil

This article comes from the American perspective and seeks to understand what we as a country can learn from Brazil’s experience with ethanol. The article first talks about the need for ethanol and how the United States is lagging behind Brazil in ethanol production. It then summarizes the history of the Brazilian ethanol program, describes the program’s current status and considers lessons for the United States from the Brazilian experience. It gives five lessons that the United States can learn from Brazil:

1. 1. Rapid expansion of ethanol production is possible with government support.

2. Consistency counts – Requiring ethanol make up a certain percentage of fuel supply

3. 3. Any ethanol program must anticipate commodity price swings

4. 4. Public attitudes can change quickly, in 1970s enthusiasm was high in late 80s was low

5. 5. Ethanol technologies improve steadily with time, between 1975 and 2000 production per hectare more than doubled and harvesting prices fell by more than half.

7. Struminski, Thiago. (April 2008). Has the world really discovered the advantages of Brazilian automotive engineering? Obtained on February 9th, 2011 from http://www.frost.com/prod/servlet/market-insight-top.pag?docid=127369340

This article showcases the automotive engineering side of Brazil. It gives a history of the development of a uniquely Brazilian approach to engineering that could not be transferred from the international companies opening up factories. Because Brazil is such a large country, with poor road conditions, and wide ranges in temperatures, engineers had to design a durable and flexible automobile. The Brazilian automotive industry has been the pioneer in producing small pick-ups and 1.0 liter engines. Cars with 1.0 liter engines account for 52 percent of all cars sold in the country. While this is impressive the true flagship automotive technology is related to alternative fuels. Flex-fuel cars, ones which allow a mixture of ethanol and gasoline, are very popular in the country and are now offered in 86 percent of new cars. These developments in engineering have led to General Motors electing Brazil as one of the five Global Engineering Centers (the others are U.S, Europe, Australia and South Korea). Even while this is happening, engineering as a profession in Brazil is woefully underrepresented. Most developed countries have an average of 25 engineers per every 1000 inhabitants; Brazil is much lower, with only six per 1000 inhabitants. To remedy this problem, local associations are trying to incentive newcomers at the very bottom of the education system creating technical courses for youngsters and fostering a culture of technology. It is a wonder if the government should be creating an engineering culture as well.
