This article examines Russian engineers’ social imagination about the future through the professional discussions held at the electrotechnical congresses in the nineteenth century. Formulating the prospective future of the industry, the state and society was a collective endeavor, a process in which the identity and mission of engineers were crystallized. Through envisioning the future of technology and its role in the society, engineers revealed their cultural role as mediators between technological innovation, and both the wider public and the state. In (...) order to better understand the manifestations of the shared cultural understandings of a desirable future and social order, the article resorts to Sheila Jasanoff’s concept of sociotechnical imaginaries. The engineering community’s sociotechnical imagination about electricity was shaped around the transformative possibilities of this technology. It was believed that electrical engineering was able not only to accelerate industrial production, but also to solve social, medical and cultural problems, thereby uniting the Russian Empire. Descriptions of the rational, comfortable and beautiful world of the electrified future overlapped in engineering discussions, journalism and science fiction. Positive scenarios emphasized the advantages of electrical engineering and bypassed the problems associated with electrification, constructing an idea of its inevitability. The electrical engineer became a kind of a new cultural hero, who knew how to make a working device or system, and also filled the task of linking the development of technology to the development of society.

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value of missing (...) data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms. (shrink)

Ethics is the science that studies the theoretical part of the human condition and its values. The individual has the responsibility to conduct ethic decisions and to have an ethical behavior. This article presents the ethics from the research and engineering perspective, its main characteristics; lack of honesty, confidentiality, conflict of interests and intellectual property. The engineering teaching is the act which includes multiple ethic subjects in order to educate the student about the importance of ethics and its repercussions. The (...) students have the right to benefit of ethical behavior from their teachers from the staff of the school. The ethic is essential in all the educational and working fields, but we insisted specially on the electrical engineering field. (shrink)

The technological breakthroughs and entrepreneurial adventures of Frank J. Sprague during the transformative years of the early electrical industry. Over the course of a little less than twenty years, inventor Frank J. Sprague achieved an astonishing series of technological breakthroughs--from pioneering work in self-governing motors to developing the first full-scale operational electric railway system--all while commercializing his inventions and promoting them to financial backers and the public. In Engineering Invention, Frederick Dalzell tells Sprague's story, setting it against the backdrop (...) of one of the most dynamic periods in the history of technology. In a burst of innovation during these years, Sprague and his contemporaries--Thomas Edison, Nicolas Tesla, Elmer Sperry, George Westinghouse, and others--transformed the technologies of electricity and reshaped modern life. After working briefly for Edison, Sprague started the Sprague Electric Railway and Motor Company; designed and built an electric railroad system for Richmond, Virginia; sold his company to Edison and went into the field of electric elevators; almost accidentally discovered a multiple-control system that could equip electric train systems for mass transit; started a third company to commercialize this; then sold this company to Edison and retired. Throughout his career, Dalzell tells us, Sprague framed technology as invention, cast himself as hero, and staged his technologies as dramas. He toiled against the odds, scraped together resources to found companies, bet those companies on technical feats--and pulled it off, multiple times. The idea of the "heroic inventor" is not, of course, the only way to frame the history of technology. Nevertheless, as Dalzell shows, Sprague, Edison, and others crafted the role consciously and actively, using it to generate vital impetus behind the process of innovation. (shrink)

The efficiency of engineering applied to civilian projects sometimes threatens to run away with the social agenda, but in military applications, engineering often adds a devastating sleekness to the inevitable destruction of life. The relative crudeness of terrorism (e.g., 9/11) leaves a stark after-image, which belies the comparative insignificance of random (as opposed to orchestrated) belligerence. Just as engineering dwarfs the bricolage of vernacular design—moving us past the appreciation of brush-strokes, so to speak—the scale of engineered destruction makes it difficult (...) to focus on the charred remains of individual lives. Engineers need to guard against the inappropriate military subsumption of their effort. Fortunately, the ethics of warfare has been an ongoing topic of discussion for millennia. This paper will examine the university core class I’ve developed (The Moral Dimensions of Technology) to meet accreditation requirements in engineering ethics, and the discussion with engineering and non-engineering students focused by the life of electrical engineer Vannevar Bush, with selected readings in moral philosophy from the Dao de Jing, Lao Tze, Cicero, Aurelius Augustinus, Kant, Annette Baier, Peter Singer, Elizabeth Anscombe, Philippa Foot, and Judith Thomson.

A case study is presented of the development of computer-based support tools for power engineers in the electricity supply industry. The objective was to develop an expert system to support witching schedule production. A user-centred approach was followed which led the user community to conclude that a switching schedule production assistant (SSPA) was required which would leave control with the power engineer. Prototype systems were developed and evaluated in user trials which revealed that a significant and more general purpose (...) tool would be a computer generated electricity network display that the engineers could manipulate. The paper concludes that the process of enabling users to evaluate alternative forms of technology can facilitate the development systems that are useful, acceptable and usable. (shrink)

Integrity is a critical determinant of the effectiveness of research organizations in terms of producing high quality research and educating the new generation of scientists. A number of responsible conduct of research (RCR) training programs have been developed to address this growing organizational concern. However, in spite of a significant body of research in ethics training, it is still unknown which approach has the highest potential to enhance researchers’ integrity. One of the approaches showing some promise in improving researchers’ integrity (...) has focused on the development of ethical decision-making skills. The current effort proposes a novel curriculum that focuses on broad metacognitive reasoning strategies researchers use when making sense of day-to-day social and professional practices that have ethical implications for the physical sciences and engineering. This sensemaking training has been implemented in a professional sample of scientists conducting research in electrical engineering, atmospheric and computer sciences at a large multi-cultural, multi-disciplinary, and multi-university research center. A pre-post design was used to assess training effectiveness using scenario-based ethical decision-making measures. The training resulted in enhanced ethical decision-making of researchers in relation to four ethical conduct areas, namely data management, study conduct, professional practices, and business practices. In addition, sensemaking training led to researchers’ preference for decisions involving the application of the broad metacognitive reasoning strategies. Individual trainee and training characteristics were used to explain the study findings. Broad implications of the findings for ethics training development, implementation, and evaluation in the sciences are discussed. (shrink)

This paper provides an empirically informed perspective on the notion of responsibility using an ethical framework that has received little attention in the engineering-related literature to date: ethics of care. In this work, we ground conceptual explorations of engineering responsibility in empirical findings from engineering student’s writing on the human health and environmental impacts of “backyard” electronic waste recycling/disposal. Our findings, from a purposefully diverse sample of engineering students in an introductory electrical engineering course, indicate that most of these (...) engineers of tomorrow associated engineers with responsibility for the electronic waste problem in some way. However, a number of responses suggested attempts to deflect responsibility away from engineers towards, for example, the government or the companies for whom engineers work. Still other students associated both engineers and non-engineers with responsibility, demonstrating the distributed/collective nature of responsibility that will be required to achieve a solution to the global problem of excessive e-waste. Building upon one element of a framework for care ethics adopted from the wider literature, these empirical findings are used to facilitate a preliminary, conceptual exploration of care-ethical responsibility within the context of engineering and e-waste recycling/disposal. The objective of this exploration is to provide a first step toward understanding how care-ethical responsibility applies to engineering. We also hope to seed dialogue within the engineering community about its ethical responsibilities on the issue. We conclude the paper with a discussion of its implications for engineering education and engineering ethics that suggests changes for educational policy and the practice of engineering. (shrink)

Based largely on unpublished manuscript material from the Kelvin papers, and especially on a series of letters exchanged in 1867 between Fleeming Jenkin and William Thomson , this paper aims to examine the background and content of the Thomson-Jenkin speculations on the nature of matter. The letters formed an interlude in a long collaboration over electrical patents and raise the fundamental question of whether these speculations, involving the construction of a variety of conceptual models, derive primarily from older traditions (...) of speculative matter theory, or from contemporary problems within natural philosophy qua physics. The correspondence also provided the immediate background to Jenkin's North British review article of 1868 on ‘Lucretius and the atomic theory’. (shrink)

The electrification of East Africa followed an exceptionally uneven path. After about 50 years of relative neglect under colonial rule, the construction of hydroelectric dams moved electricity generation into the focus of late colonial development policy and became the major field of intervention for foreign donors after independence. The metrics of electricity attained a role as indicator and driver for economic growth, and therefore as a target figure in economic policy, one that was arguably not justified by their actual significance (...) in the energy landscape of East Africa. This paper analyses both the global preconditions of this shift and its local repercussions. Rather than the physical visibility of electricity in the form of large dams and high-tension lines, the paper focuses on the processes that rendered electricity ontologically visible. It traces attempts by engineers, expert advisors, or development consultants to translate the complex information associated with the generation and consumption of electricity into calculable and comparable metrics. The paper scrutinises these commensuration processes in terms of the resources and knowledge they required, the frameworks of agency they opened, and the way they fed into wider discourses of development. It asks how the metrics of electricity themselves became part of the colonial and postcolonial politics of calculation, as they increasingly came to be seen as a medium for conceiving national economies. This trend was reinforced by the ascent of development economics in the 1950s and its influence on the ontological foundations of international development cooperation and post-independence nation-building. Because of the calculability and capital-intensity of its production, electricity lent itself perfectly to an economic policy based on macroeconomic aggregates and abstract growth models. Conversely, the electricity bias of international development agencies and the national government rendered rural, non-commercial, and non-productive energy use largely invisible. (shrink)
