Birds of a Feather? How Politics and Culture Affected the Designs of the U.S. Space Shuttle and the Soviet Buran

Garber, Stephen J. 04 February 2002 (has links)
What can we learn from comparing similar technologies that were designed and built in different countries or cultures? Technical products depend upon both technical and non-technical goals as socio-cultural factors determine which projects get funded and how they are conceived, designed, and built. These qualitative socio-cultural factors mean that there is almost always more than one possible design solution for a particular problem. By comparing how two major space projects were conceptualized and designed in the United States and Soviet Union, this case study aims to illuminate more broadly how political and cultural factors can influence the selection of technical designs, as well as the general conduct of engineering and science, in the space sector. / Master of Science

Obesity and the Technological Fix: Weight Loss Surgery in American Women

Augustine, Donna Marie 03 September 2003 (has links)
This thesis is an analysis of how societal values shape our ideas of health and disease, the designs and marketing of weight loss surgery technologies, and the ways in which obesity reducing-operations are accepted and desired. Gender ideologies, American values of commodity capitalism, treatment that focuses on the individual, and a moral aversion to fat have all shaped the medical treatment of obesity as an epidemic and the promotion of weight loss surgery as the best available solution. In this project, I approach the question of obesity by deconstructing the terms that have framed it as a social problem and I show how and why specific technological remedies have been pursued. My thesis is that among obese Americans, females and their bodies are especially stigmatized and pathologized. Because of this, efforts and applications of science, technology, medicine, and policy focus to "fix" these bodies/people, which are considered out of control. / Master of Science

Water is More Important than Gold: Local Impacts and Perceptions of the 1995 Omai Cyanide Spill, Essequibo River, Guyana

Ramessar, Candice Rowena 21 August 2003 (has links)
Improved technologies, increases in global demand for metals, and lax environmental policies and regulations are causing a shift of large-scale mining activities to the tropics. This shift of mining to the tropics has the potential to modify natural ecosystems and disrupt the social structures of rural and indigenous peoples in some of the most remote areas of the planet. This thesis encompasses research done in two villages of Guyana's Essequibo River basin after the 1995 Omai cyanide spill, and illustrates the local social consequences of a large-scale gold mining operation in the tropics. It documents not only the degradation of the local river ecology, but also the changes in local people's perceptions of their environment. That environment, once viewed as pristine, is now viewed as unsafe, leading to disrupted livelihoods and lifestyles. The finding of this study points to a direct link between international economic liberalization policies (which emphasize privatization, foreign direct investment, and economic growth) and the creation of disaster circumstances in developing countries. This thesis research is the result of a total of ten weeks of participant observer research in the area of the Essequibo River, Guyana. It utilizes the methodology of taped interviews of head-of-households. Interviews were conducted with approximately 85 percent of heads-of household of the villages of Rockstone and Riversview. Additionally, interviews were conducted with national and regional governmental officials, regional health officials, local and indigenous leaders, personnel of the Guyana Geology and Mines Commission, and the Environmental Protection Agency in Guyana. Interviews were supplemented with archival research. The findings of this thesis research closely mirror those of other researchers who contend that the social impacts of technological disasters are long-term and more severe than those related to natural disasters. Seven years after the cyanide spill, disruptions in livelihood activities, diet, and household behaviors continued to be evident in the two villages. There is little indication that the high negative perceptions of the villagers as a result of the disaster will change in the near future. The research found that macroeconomic policies, crafted by national governments and overseen by international financial institutions without the involvement of local citizenry, disproportionately affected the poor and rural populations through the degradation of local ecosystems. The thesis also illustrates the usefulness of ethnographic research-in particular, interviews in disaster studies of developing countries. / Master of Science

An electropneumatic teststand for teaching control to engineering undergraduates

Tripodi, Michael A. 25 April 2009 (has links)
Agricultural operations such as harvesting and sorting typify controlled processes. Engineering students who wish to specialize in automatic control often do not get sufficient experience in the integration of the three areas of a complete control system: sensors, computing, and actuation. A teststand was designed and built for laboratory exercises which illustrate the inter-relationship of sensors, computing, and actuation in a sorting operation. Black, gray, and white blocks were placed on a conveyor and moved past two sensors which provided color and position information to a control program. Based upon the information provided by the sensors, the control algorithm activated pneumatic cylinders that sorted the blocks. Two algorithms, identified as open-loop and closed-loop, were tested. For the open-loop tests, the conveyor moved at constant velocity, and for the closed-loop tests, conveyor velocity was cycled. The algorithms calculated the delay between the time a block passed the position sensor and the point where the block was struck by a cylinder, and adjusted the actuation time accordingly. Tests were run at conveyor speeds between 10 and 80 cm/s. Using the open-loop algorithm, 99.7% of the blocks were identified and struck by the correct cylinder, and for the closed-loop algorithm the accuracy was 98.6%. The control program was written in C and executed on an IBM PC. Three laboratory exercises at various levels of difficulty were developed for the teststand. / Master of Science

An evaluation of the planning and control system required for technology management in an engineering business

Pentz, R. D. 12 1900 (has links)
Script contains articles in Afrikaans and some text also in Afrikaans / Opportunities abound in the Armaments industry is South Africa and abroad. This is probably one of the main reasons why it has grown to almost astronomical amounts in va lu e . Simultaneously, the vast f igures in turnover and profits have attracted numerous competitors into the business. The next factor which has contributed most significantly to the increase in development and manufacture of armaments is of course the need of countries to defend themselves against aggressors. Political unrest , terrorism , border conflicts , war and invasions are the order of the day. All of these events require a show of arms, if not retaliation . In order to satisfy a need for strategic independence, even to a limited extent , countries have insisted on development and establishment of various categories of technologies. During the past fifty years there has been an explosion in the amount of information published in the technology sector. Some highly sophisticated technologies have become commonplace in most technical fields , including the armaments industry . As might be expected, the armaments industry is also greatly influenced by trends and change in the sector of economics, by social and cultural factors , and new legislation. It may rightfully be regarded as a highly volatile , complex and dynamic part of any economy. Under these circumstances the role of technology management in a country and in a business enterprise becomes more important, more difficult , and more essential. To ensure that a large organisation stays competitive, or becomes more competitive, the system of planning and control must be well integrated , kept up to date, and well/managed to fulfil its purpose. For the purpose of this script an investigation was undertaken into the corporate and business systems for technology management in a firm in the local engineering industry . The description covers planning and control theory, system models, innovation and technology management principles , and the theory of forecasting methods usually adapted for technology predictions , Evaluation of the practical systems which are in place and are being utilised , led to a few significant observations and conslusions. The investigation was by no means exhaustive, but was aimed at getting an overview of the corporate and business systems as they operate with in the stated strategic frameworks. It is concluded that technology planning and control systems are well-developed, highly integrated and applied in a top-down fashion . Not all aspects are conducted as efficiently as should be possible. Also, due to the dynamic nature of the industry, effectiveness can still improve for the company. Moves are afoot to meet new challenges and requirements and there is no doubt that the future will see great achievements. / Business Management / M.B.L.

Biplane to monoplane : twenty years of technological development in British fighter aircraft, 1919-1939

Kelly, Paul January 2014 (has links)
In the summer of 1940 around five thousand aircraft clashed during several months for control of the skies over Britain. The fighter aircraft used by the German Luftwaffe and British Royal Air Force were, for the most part, very similar. They were monoplane airframes made with a metal structure and covered with fabric or metal skin, their engines produced around 1,000 h.p., and the aircraft themselves achieved speeds of around 350 to 370 m.p.h. They had retractable undercarriages and were bristling with armaments. These aircraft stood in stark contrast to those used just over twenty years earlier in the First World War. Those machines were biplanes, almost exclusively made from wood, covered in a doped fabric, their engines produced around 400 h.p., with speeds at around 120 m.p.h., they had fixed undercarriages, one or two machine guns and were largely un-armoured. In a little over twenty years the basic form of fighter aircraft had changed, and the materials used in their construction had changed. The engines, guns, interior structure and even the operational roles to which they were assigned had been altered to greater or lesser extents. The period 1918-1939 was, therefore, very important in the development of British fighter aircraft, as it was in aviation technology more generally. The inter-war period suggested itself for several reasons. Firstly, the historiography upon which part of this thesis is hinged deals largely with its latter years and the years leading to World War Two. Due to this concentration on the mid-late 1930s, there is no real sense of what was going on in the 1920s, or attempts to understand the changes that the technology, and the institutions behind them, went through over the years. Secondly, following the First World War, the British aircraft industry was possessed of some considerable degree of competence and experience. To study the development of aviation technology before the war would be to catalogue the efforts of a number of pioneers each doing their own thing and following their own beliefs. To look at such development during the First World War would be to look at what happens when money is no serious object to research and development, production space, labour, management and so on. In looking at the inter-war years, we can examine a new industry that has just come out of a very considerable baptism of fire (in the case of Britain this baptism came just five years after her first successful flight was conducted). We can examine an industry that had to deal with enormous cutbacks, governmental micromanagement and lacking, for a long time, a fertile market in which to operate. Furthermore, the twenty years of the inter-war period allows us to look at a protracted period of technological change enabling us to account for the many varied and changing factors influencing the development of British fighter aircraft. Finally, the approach of the Second World War, the danger of Adolf Hitler and National Socialism and the proliferation of the Luftwaffe was not lost on policymakers and so this period also allows us to examine the effects of wider international events on technology. As it will be shown in the section dealing with historiography there has been plenty of work examining the British aircraft industry, individual aircraft and even the technologies which appeared over the twenty years that this thesis covers. However, there has been a great scarcity of work attempting to explain how such technologies appeared, how they linked together and how aircraft technology changed over the period. These are important questions, not only in terms of providing comprehensive explanations for their creation, development and existence but also in providing crucial context when attempting to pass judgement (as many historians have done) on the industry and the technology it created, and the politics and bureaucracy involved in shaping the technology. Using the example of British fighter aircraft during the 1920s and 1930s, this thesis will look at how the pace of technological change was set. How and why did British fighter aircraft develop the way they did and at the pace that they did? In particular, it will address the central issue of how the shift from the wooden biplanetype fighter of 1918 to the metal monoplane-type of 1939 came about. And can this change be conceptualised as a ‘paradigm shift’ from one ‘technological paradigm’ to another? This is particularly interesting because many consider that aviation now needs to carry out another paradigm shift, due to concerns about environmental impacts, especially as regards climate change.

The functionality grid as paradigm for management of technology

Lochner, Frederick Christoffel 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2011. / Technology is a critical component in modern society. Management of Technology (MOT) should be a major focus of management studies. At present the status of MOT is much less than it should be. Part of the reason is that there is little consensus about the body of knowledge for MOT. This can be traced down to as far as an inadequate consensus about the very nature of technology itself. There is a need for a simple and elegant conceptual foundation. There is a need for an accepted paradigm to govern MOT. The paradigm discourse initiated by Thomas Kuhn allows for a comprehensive frame of reference about theory contestation and about the attributes required from a contesting theory to achieve the ultimate status of a paradigm. In order to help create a coherent and streamlined conceptual foundation for MOT, this research evaluates the functionality grid as a paradigm. To realise this goal, this study first assesses the functionality grid’s compliance with the theoretical requirements of a paradigm, and secondly its compliance with the empirical requirements of a paradigm. The theoretical test uses a newly created format, the paradigm template, to establish the necessary criteria. The functionality grid is then subjected to a critical review using the said criteria. It is found that it meets the requirements of a valid paradigm. For measurement of empirical requirements, Kuhn’s own criteria are used. This second part of the study involves three practical exercises to examine the practical descriptive power of the functionality grid, and its ability to help first with the formation of a technology attuned mindset of participants, second with the improvement in technological knowledge and third with an increase in the technological literacy of participants. The outcomes of these tests are positive as well. The dissertation concludes that the functionality grid would be a viable paradigm to serve as a guide for the further development of MOT. The functionality grid becomes confirmed as a paradigm for MOT, because it contains all the attributes to serve as a coherent and streamlined conceptual structure for this discipline. Given this outcome, it is recommended that more effort be invested to understand, promote and popularise the functionality grid; and the various analytical frameworks derived from it. It is recommended that it becomes an explicit part of the book of knowledge for MOT and that it constitutes the basis for an educational curriculum to be shared by every MOT professional and student.

A strategic business approach for sustainable e-participation at local government level

24 April 2015 (has links)
M.Com. (Business Management) / Since the dawn of democracy, South Africa has experienced continued service delivery protests. The extent to which these protests manifest themselves could be indicative of the communication gap that exists between local councillors and communities. In response, communities might use protests to serve as a medium of communication to highlight their unhappiness with service delivery. The e-participation programme is an intervention introduced by the German International Cooperation to explore the potential and assist municipalities with the implementation of a short message system-based, two-way channel for citizen-municipality communication. This study examined the level of readiness of municipalities with regard to the implementation and the sustainability of the e-participation programme. It used a mixed method approach to investigate a sample of municipalities. Findings and recommendations to government on considerations for implementation of the programme is discussed. The study concludes by highlighting earned benefits that can be enjoyed by all South African municipalities by employing the core pillars of various models used in other countries in implementing e-participation.

The Historical Development and Future of the National Technological University

Mays, Marilyn Elaine 08 1900 (has links)
The National Technological University (NTU), a consortium of more than twenty American engineering schools, broadcasts courses produced at member institutions to professional engineers at corporate sites across the country. It is a nonprofit institution.begun in fall 1984 with headquarters in Fort Collins, Colorado, which offers only course work leading to the Master of Science degree in various branches of technology, or applied science. Students must be sponsored by their corporate employers who pay their tuition. This is the first systematic examination of the instructional process at an educational institution created in response to the demands of the governmental and corporate sectors' technological needs. This study includes an attempt to explore the effectiveness of that instructional process and the use of computers in distance education at NTU and implications for institutions of the future. This study focuses on distance education, corporate education, national universities and nontraditional institutions and the extent to which NTO exemplifies each of these concepts. It covers the organizational structure and methods of operation of NTU, and offers opinions of students, faculty, and other personnel associated with the institution as reflected by surveys, interviews, and the media.
