An account of conflicts within engineering in the 1960s that helped shape our dominant contemporary understanding of technological change as the driver of history.
In the late 1960s an eclectic group ...of engineers joined the antiwar and civil rights activists of the time in agitating for change. The engineers were fighting to remake their profession, challenging their fellow engineers to embrace a more humane vision of technology. In Engineers for Change, Matthew Wisnioski offers an account of this conflict within engineering, linking it to deep-seated assumptions about technology and American life.
The postwar period in America saw a near-utopian belief in technology's beneficence. Beginning in the mid-1960s, however, society—influenced by the antitechnology writings of such thinkers as Jacques Ellul and Lewis Mumford—began to view technology in a more negative light. Engineers themselves were seen as conformist organization men propping up the military-industrial complex. A dissident minority of engineers offered critiques of their profession that appropriated concepts from technology's critics. These dissidents were criticized in turn by conservatives who regarded them as countercultural Luddites. And yet, as Wisnioski shows, the radical minority spurred the professional elite to promote a new understanding of technology as a rapidly accelerating force that our institutions are ill-equipped to handle. The negative consequences of technology spring from its very nature—and not from engineering's failures. “Sociotechnologists” were recruited to help society adjust to its technology. Wisnioski argues that in responding to the challenges posed by critics within their profession, engineers in the 1960s helped shape our dominant contemporary understanding of technological change as the driver of history.

Products and services based on advanced technologies such as artificial intelligence and blockchain are normally considered to be for rich consumers in advanced countries. Fourth Revolution and the ...Bottom Four Billion demonstrates how marginalized and vulnerable groups with limited resources can also benefit from these technologies. Nir Kshetri suggests that the falling costs and the increased ease of developing and deploying applications based on these technologies are making them more accessible. He illustrates how key emerging technologies are transforming major industries and application areas such as healthcare and pandemic preparedness, agriculture, finance, banking, and insurance. The book also looks at how these transformations are affecting the lives of low-income people in low- and middle-income countries and highlights the areas needing regulatory attention to adequately protect marginalized and vulnerable groups from the abuse and misuse of these technologies. Kshetri discusses how various barriers such as the lack of data, low resource languages, underdeveloped technology infrastructures, lack of computing power and shortage of skill and talent have hindered the adoption of these technologies among marginalized and vulnerable groups. Fourth Revolution and the Bottom Four Billion suggests that it is the responsibility of diverse stakeholders—governments, NGOs, international development organizations, academic institutions, the private sector, and others—to ensure that marginal groups also benefit from these transformative innovations.
Over the past five centuries, advances in Western understanding of and control over the material world have strongly influenced European responses to non-Western peoples and cultures. InMachines as ...the Measure of Men, Michael Adas explores the ways in which European perceptions of their scientific and technological superiority shaped their interactions with people overseas. Adopting a broad, comparative perspective, he analyzes European responses to the cultures of sub-Saharan Africa, India, and China, cultures that they judged to represent lower levels of material mastery and social organization.
Beginning with the early decades of overseas expansion in the sixteenth century, Adas traces the impact of scientific and technological advances on European attitudes toward Asians and Africans and on their policies for dealing with colonized societies. He concentrates on British and French thinking in the nineteenth century, when, he maintains, scientific and technological measures of human worth played a critical role in shaping arguments for the notion of racial supremacy and the "civilizing mission" ideology which were used to justify Europe's domination of the globe. Finally, he examines the reasons why many Europeans grew dissatisfied with and even rejected this gauge of human worth after World War I, and explains why it has remained important to Americans.
Showing how the scientific and industrial revolutions contributed to the development of European imperialist ideologies,Machines as the Measure of Menhighlights the cultural factors that have nurtured disdain for non-Western accomplishments and value systems. It also indicates how these attitudes, in shaping policies that restricted the diffusion of scientific knowledge, have perpetuated themselves, and contributed significantly to chronic underdevelopment throughout the developing world. Adas's far-reaching and provocative book will be compelling reading for all who are concerned about the history of Western imperialism and its legacies.
First published to wide acclaim in 1989,Machines as the Measure of Menis now available in a new edition that features a preface by the author that discusses how subsequent developments in gender and race studies, as well as global technology and politics, enter into conversation with his original arguments.
In this engaging volume, Jon Dron views education, learning, and teaching through a technological lens that focuses on the parts we play in technologies, from language and pedagogies to computers and ...regulations. He proposes a new theory of education whereby individuals are not just users but co-participants in technologies—technologies that are intrinsic parts of our cognition, of which we form intrinsic parts, through which we are entangled with one another and the world around us. Dron reframes popular families of educational theory (objectivist, subjectivist, and complexivist) and explains a variety of educational phenomena, including the failure of learning style theories, the nature of literacies, systemic weaknesses in learning management systems, the prevalence of cheating in educational institutions, and the fundamental differences between online and in-person learning. Ultimately, How Education Works articulates how practitioners in education can usefully understand technology, education, and their relationship to improve teaching practice.

A vivid look at China's shifting place in the global political economy of technology production How did China's mass manufacturing and "copycat" production become transformed, in the global tech ...imagination, from something holding the nation back to one of its key assets? Prototype Nation offers a rich transnational analysis of how the promise of democratized innovation and entrepreneurial life has shaped China's governance and global image. With historical precision and ethnographic detail, Silvia Lindtner reveals how a growing distrust in Western models of progress and development, including Silicon Valley and the tech industry after the financial crisis of 2007–8, shaped the rise of the global maker movement and the vision of China as a "new frontier" of innovation.Lindtner's investigations draw on more than a decade of research in experimental work spaces—makerspaces, coworking spaces, innovation hubs, hackathons, and startup weekends—in China, the United States, Africa, Europe, Taiwan, and Singapore, as well as in key sites of technology investment and industrial production—tech incubators, corporate offices, and factories. She examines how the ideals of the maker movement, to intervene in social and economic structures, served the technopolitical project of prototyping a "new" optimistic, assertive, and global China. In doing so, Lindtner demonstrates that entrepreneurial living influences governance, education, policy, investment, and urban redesign in ways that normalize the persistence of sexism, racism, colonialism, and labor exploitation. Prototype Nation shows that by attending to the bodies and sites that nurture entrepreneurial life, technology can be extricated from the seemingly endless cycle of promise and violence.Cover image: Courtesy of Cao Fei, Vitamin Creative Space and Sprüth Magers
Blockchain technology (BT) is expected to bring a revolutionary paradigm shift in the manner the transactions are carried in the supply chains. BT provides better visibility and transparency by ...removing the disadvantages of trust related issues in a supply chain. In this paper, we advance the literature on BT and its adoption in the supply chain by developing, and statistically validating a model for understanding the user perceptions on BT adoption. The model is based on the integration of three adoption theories- technology acceptance model (TAM), technology readiness index (TRI) and the theory of planned behaviour (TPB). Based on a survey of 181 supply chain practitioners in India the proposed model was tested using structural equation modelling. The study found that the TRI constructs- Insecurity and discomfort have an insignificant effect on the perceived ease of use and usefulness. Perceived usefulness, attitude, and perceived behavioural control affect the behavioural intention. Subjective norm has a negligible impact on behavioural intention. This is one of the preliminary studies on BT adoption in supply chain and the findings imply that the supply chain practitioners perceive BT adoption free of efforts and would help them to derive maximum benefits for improving the supply chain effectiveness.
