Debates about terrorism and technology often focus on the potential uses of technology by non-state terrorist actors and by states as forms of counterterrorism. Yet, little has been written about how technology shapes how we think about terrorism. In this chapter I argue that technology, and the language we use to talk about technology, constrains and shapes our understanding of the nature, scope, and impact of terrorism, particularly in relation to state terrorism. After exploring the (...) ways in which technology shapes moral thinking, I use two case studies to demonstrate how technology simultaneously hides and enables terroristic forms of state violence: police control technologies and Unmanned Aerial Vehicles (UAVs), or drones. In both these cases, I argue that features of these technologies, combined with a narrative of precision and efficiency, serves to mask the terroristic nature of the violence that these practices inflict and reinforces the moral exclusion of those against whom these technologies are deployed. In conclusion, I propose that identifying acts of terrorism requires a focus on the impact of technologies of violence (whether they are “high tech” or not) on those most affected, regardless of whether users of these technologies conceive of their actions as terroristic.

Relying on social capital to promote farmers’ adoption of green control technology is of great significance for the governance of rural environment and the realization of sustainable agricultural development. Based on the survey data of 754 farmers in Shandong Province, this paper uses the Probit model and the instrumental variable method to empirically analyze the impact of social capital on farmers’ green control technology adoption behavior. The results show that: social capital has a promoting influence on farmers’ green (...) control technology adoption behavior; the influence of the three dimensions of social capital on farmers’ green control technology adoption behavior is in turn social norms, social networks, and social trust; social networks play an enhanced moderating role in the process of social trust and social norms promoting farmers’ green control technology adoption behavior; education level, the number of family labor force and annual family income level have a significant positive impact on farmers’ green control technology adoption behavior, while age has a significant negative impact. Therefore, the government should make full use of social capital to promote farmers to adopt green control technology. (shrink)

This article draws on the suggestion that modern technology is “autonomous” in that our social control mechanisms are unable to control technology and instead merely adapt society to integrate new technologies. In this article, I suggest that common law judges tend systematically to support the integration of novel technologies into society. For example, courts sometimes require parties seeking compensation for serious injuries to submit to medical technologies to which the parties object for genuine reasons of fear or moral (...) objection. Where a novel technology alters the environment in some way, courts sometimes legitimize that alteration by refusing to recognize harm and instead characterizing avoidance of the technology as self-imposed harm. The examples selected in this article were chosen to support the hypothesis in one way or another, and future work will aim to look for counter examples and to conduct a more complete assessment of the hypothesis.

Despite the importance of knowing the cognitive capabilities of children with neurodevelopmental conditions, less than one-third of children with cerebral palsy participate in standardized assessments. Globally, approximately 50% of people with cerebral palsy have an intellectual disability and there is significant risk for domain-specific cognitive impairments for the majority of people with cerebral palsy. However, standardized cognitive assessment tools are not accessible to many children with cerebral palsy, as they require manual manipulation of objects, verbal response and/or speeded response. As (...) such, standardised assessment may result in an underestimation of abilities for children with significant motor and/or speech impairment. The overall aim of the project is to examine and compare the psychometric properties of standardised cognitive assessment tools that have been accommodated for use with either a switch device or eye-gaze control technologies, with the specific aims to: Examine the psychometric properties of accommodated assessment tools by comparing the performance of typically developing children on six cognitive assessment tools administered via standardised versus accommodated administration; Describe and compare the performance and user experience of children with cerebral palsy on six accommodated cognitive assessments administered via switch or eye-gaze control technologies. Secondary aims are to: Describe the completion rates and time to complete assessments of participants in each group; Within the group with cerebral palsy, examine the effects of condition-specific characteristics and demographics on participation. This protocol paper describes a two-phase validation and acceptability study that utilizes a mixed-model design. This study will collect concurrent data from 80 typically developing children and 40 children with cerebral palsy, who use switch or eye-gaze control technology as alternate access communication methods. The set of instruments will measure receptive vocabulary, fluid reasoning, sustained attention, vision perception, visuospatial working memory and executive functions. Data analyses will be conducted using SPSS v. 25 and R v 4.1.0. SPSS Sample Power 3 was used for power computation and allows for a 10% drop out rate. Quantitative descriptive statistics, measurement agreement data plotting, bivariate and multiple regressions analysis will be conducted using appropriate methods. (shrink)

New technologies are often introduced with the purpose of improving our control over a certain task: however, software, AI and robots often cause understandable fears of machines taking control away from us. This is what Ezio Di Nucci calls the ‘control paradox’.

The truth of the matter is that our deficiency does not lie in the want of well-verified "facts." What we lack is our bearings. The contemporary experience of things technological has repeatedly confounded our vision, our expectations, and our capacity to make intelligent judgments. Categories, arguments, conclusions, and choices that would have been entirely obvious in earlier times are obvious no longer. Patterns of perceptive thinking that were entirely reliable in the past now lead us systematically astray. Many of our (...) standard conceptions of technology reveal a disorientation that borders on dissociation from reality. And as long as we lack the ability to make our situation intelligible, all of the "data" in the world will make no difference.;From the Introduction. (shrink)

La surveillance de masse peut être considérée comme un trait caractéristique des sociétés modernes. Son importance n’a d’égal que les moyens mis en place pour recueillir et amasser des renseignements. Parmi ces moyens, les nouvelles technologies de surveillance et de contrôle et surtout les manières de les déployer soulèvent un certain nombre d’enjeux éthiques qui, en avril 2008, ont fait l’objet d’un avis de la Commission de l’éthique de la science et de la technologie : Viser un juste équilibre : (...) un regard éthique sur les nouvelles technologies de surveillance et de contrôle à des fins de sécurité́. S’appuyant sur cette réflexion, cet article a pour objectif de montrer en quoi le déploiement des nouvelles technologies de surveillance et de contrôle constituera un défi pour la réflexion éthique dans la prochaine décennie. Les grandes lignes de l’avis et les technologies qui y sont abordées sont brièvement présentées. (shrink)

In this paper I argue that the technologizing of most things in our daily lives, from work and education to finance and leisure, can be seen to promote a loss of the tangible and a rootlessness for human societies, causing a disorientation in the knowledge and beliefs acquired over millennia. Arendt’s proposal that ‘the earth is the very quintessence of the human condition’ (1958, p. 2) appears to be challenged as digital interactions create new spaces that coax humans away from (...) a focus on their physical world. Instantaneity and simultaneity avoid the historic conditions of humanity in relation to time and place, while the hyperreal images and simulations of the virtual either distort reality or do not depict anything with a real existence. Stiegler goes so far as to suggest that human knowledge and memory is being confiscated by technology. The acceleration of reality, as a condition of the instant, erases the beginning as much as the end, and past, present and future are diminished as contemporary becomes simply temporary. My position, while not utopian, does not seek to be irrationally dystopian and accepts that there is much in technology that advances human physical well-being and thought. It is, however, cautionary in its concern that private technology corporations, having seconded science, actively seek to increase their market and control over hyperconnectivity, thinking, knowledge and the human condition. I draw on the writings of Stiegler and Virilio in particular, both of whom acknowledge a debt to Heidegger. (shrink)

The mastery of contemporary scientific and technological revolution is both a consequence and a condition of the purposeful control of social processes. Bourgeois social sciences failed to elaborate a comprehensive theory of social control since they ignore the social subject of the cognition and control of social processes. The scientific concept of social control arises due to the Marxist-Leninist analysis of the subject-object dialectic in the historical process with the formation of the advanced socialist society.

The article brings to light the use of recommender systems as technologies of the self, complementing the observations in current literature regarding their employment as technologies of ‘soft’ power. User practices on the music recommendation website last.fm reveal that many users do not only utilize the website to receive guidance about music products but also to examine and transform an aspect of their self, i.e. their ‘music taste’. The capacity of assisting users in self-cultivation practices, however, is not unique to (...) last.fm but stem from certain properties shared by all recommendation systems. Furthermore, unlike other oft-studied digital/web technologies of the self which facilitate ‘self-publishing’ vis-à-vis virtual companions in social media, recommender algorithms themselves can act as ‘intimate experts’, accompanying users in their self-care practices. Thus, recommendation systems can facilitate both algorithmic control and creative self-transformation, which calls for a theorization of this new cultural medium as a space of tension. (shrink)

Scholarship on technological change in academe suggests that the adoption of instructional technologies will erode professional control. Researchers have documented the pervasiveness of new technologies, but neither demonstrate how technological change is experienced by faculty nor collect data that permit assessment of consequences for professional control. Drawing on a sample of interviews with forty-two professors at three research-intensive universities, this research makes two contributions to existing research. First, in contrast to existing depictions of technological change in higher education, the findings (...) reveals that academics perceive instructional technologies to have limited value in enhancing education and that technology use is rarely motivated by pedagogical innovation. Second, the study suggests that a relationship between technological change and “unbundling” of the academic role may be overstated. These data indicate that technological change threatens professional autonomy through exclusion from decision-making processes, increased workloads, and delimited teaching and research roles.

Since the publication of ChatGPT and Dall-E, there has been heavy discussions on the possible dangers of generative artificial intelligence (AI) for society. These discussions question the extent to which the development of AI can be regulated by politics, law, and civic actors. An important arena for discourse on AI is the news media. The news media discursively construct AI as a technology that is more or less possible to regulate. There are various reasons for an assumed regulatability. Some (...) voices highlight the predominant capitalism of modern society as an ideology that enforces an uncontrolled development of AI. Others call on the rationality of civic society, which will push AI toward a development that serves humankind. Summarized, the discourse on AI floats between positions of technological and social determinism. The article conducts a discourse analysis on 113 articles from the German newspapers Süddeutsche Zeitung and Frankfurter Allgemeine Zeitung. The analysis shows how these center-left and center-right media frame the AI development in terms of social and technological determinism. As these newspapers reach out to a large audience, the article shows the kinds of perspectives on AI that confront civic society in Germany every day. News media can motivate or impede social action, as they frame the potential necessity of society and its members to intervene against certain developments. The article shows how the newspapers promote an understanding of AI, by which citizens will feel motivated to insist on a regulation of AI by politics and law. (shrink)

Progress in the technical means of monitoring to verify compliance to arms control treaties is discussed in the following areas: Real-time surveillance with charge-coupled devices in the visible and infrared; image enhancement with digital 1 image processing and with adaptive optics; imaging with radars based on satellites and on the ground; seismic monitoring with high frequency discrimination and with unattended in-country seismic stations; and nuclear weapons test monitoring with the global positioning satellite system.

This paper argues that many so-called digital technologies can be construed as notational technologies, explored through the example of Monegraph, an art and digital asset management platform built on top of the blockchain system originally developed for the cryptocurrency bitcoin. As the paper characterizes it, a notational technology is the performance of syntactic notation within a field of reference, a technologized version of what Nelson Goodman called a “notational system.” Notational technologies produce abstracted entities through positive and reliable, or (...) constitutive, tests of socially acceptable meaning. Accordingly, this account deviates from typical narratives of blockchains, instead demonstrating that blockchain technologies are effective at managing digital assets because they produce abstracted identities through the performance of notation. Since notational technologies rely on configurations of socially acceptable meaning, this paper also provides a philosophical account of how blockchain technologies are socially embedded. (shrink)

ABSTRACTThe quartz clock, the first to replace the pendulum as the time standard and later a ubiquitous and highly influential technology, originated in research on means for determining frequency for the needs of telecommunication and the interests of its users. This article shows that a few groups in the US, Britain, Italy and the Netherlands developed technologies that enabled the construction of the new clock in 1927–28. To coordinate complex and large communication networks, the monopolistic American Telephone and Telegraph (...) Company, and national laboratories needed to determine and maintain a common ‘standard’ frequency measurement unit. Exploiting novel piezoelectric quartz methods and valve electronics techniques, researchers in these organizations constructed a new crystal-based frequency standard. To ensure its accuracy they compared it to an accepted absolute standard - an astronomical clock, constructing thereby the first quartz clock. Other groups, however, had different, though connected, technological aims, which originated from the diverse interests of the industrial, governmental and academic institutes to which they belonged, and for which they needed to measure, control and manipulate with frequencies of electric oscillations. The present article suggests a comparative examination of the research and development paths of these groups on their incentives, the technological and scientific resources they utilized, and the kind of research carried out in the various institutional settings.

In this paper, the concept of Human-Centred Technology will be described with regard to the different dimensions of workplace, groupwork and networks and in terms of the frameworks of both society and the natural environment. These different aspects of Human-Centred Systems will be illustrated by a series of case studies representing several European countries. The report covers a wide range of research fields. The emphasis is on technology: the roles of control and information technology in enterprises today (...) — including issues of applying AI — and the strategies of designing and implementing technology taking into account the specific aspects which characterize human-centred systems.

A system of environmental ethics recently developed by Lawrence Johnson may be used to analyze the moral implications of biological control. According to this system, entities are morally relevant when they possess well-being interests (i.e., functions or processes that can be better or worse in so far as the entity is concerned). In this formulation of ethical analysis, species and ecosystems are morally relevant because they are not simply aggregates of individuals, so their processes, properties, and well-being interests are not (...) reducible to the sum of their individual members. Following Johnson's thesis, species and ecosystems have morally relevant interests in surviving and maintaining themselves as integrated wholes with particular self-identities. This theoretical structure gives rise to a number of ethical criteria that are particularly relevant to biological control, which apply to the ecosystem (the extent to which it is large, native, unique, and integrated) and to the action being considered (the extent to which it is novel, omnipresent, monitored, reversible, and necessary). In these terms, it is evident that not all biological control efforts are ethically defensible. In general terms, natural biological control is most desirable, followed by augmentative strategies, classical approaches, and finally neoclassical biological control. Two specific cases (neoclassical biological control of rangeland grasshoppers and classical biological control of prickly pear cactus) illustrate the ethical concerns. Finally, it can be shown that formalized restrictions of biological control are necessary, given the unique properties of this technology. (shrink)

In their paper, “Autonomy and the ethics of biological behaviour modification”, Savulescu, Douglas, and Persson discuss the ethics of a technology for improving moral motivation and behaviour that does not yet exist and will most likely never exist. At the heart of their argument sits the imagined case of a “moral technology” that magically prevents people from developing intentions to commit seriously immoral actions. It is not too much of a stretch, then, to characterise their paper as a (...) thought experiment in service of a thought experiment. In order for an argument involving a thought experiment to progress debate in applied ethics three things must be true. First, the thought experiment must accurately represent and illuminate a pressing ethical dilemma. Second – and most obviously – the central claims of the argument regarding the thought experiment must be plausible. Third, it must be possible to apply or develop the arguments established with reference to the thought experiment to the real world cases the experiment is intended to illuminate. In this commentary, I argue that there are serious reasons to question the extent to which their argument meets each of these challenges involved in the use of thought experiments in applied ethics. While Savulescu et al. succeed in showing how behavioural modification might be compatible with freedom and autonomy – and perhaps justifiable even if it were not — in the fantastic case they consider, there is little we can conclude from this about any technology of “moral bioenhancement” in the foreseeable future. Indeed, there is a real danger that their argument will license attempts to manipulate behaviour through drugs and brain implants, which raise profound moral issues that they barely mention.

Under the innovation-driven development strategy, the improvement of the core competitiveness of enterprises demonstrates increasing dependence on the ability of technological innovation. In this article, data of A-share listed companies in Shanghai and Shenzhen stock markets from 2008 to 2018 were selected as research samples for the analysis of the influencing factors and mechanism of enterprise technological innovation from the dual perspectives of the external economic environment and internal management system based on the use of the fixed-effect model. The results (...) show that government intervention significantly hinders enterprises' investment in resources for technological innovation, and less government intervention can improve the innovation investment of enterprises. The intervention of internal control fails to bring institutional advantages; rather, it aggravates the negative effect of government intervention on enterprise technological innovation. The research enriches the existing academic research results on government intervention, internal control quality, and enterprise technological innovation. The findings provide experience for accelerating the marketization process in China, enterprise governance, and improving the level of enterprise technological innovation. (shrink)

Mobile phone-based applications (apps) can promote faster targeted actions to control COVID-19. However, digital contact tracing systems raise concerns about data security, system effectiveness, and their potential to normalise privacy-invasive surveillance technologies. In the absence of mandates, public uptake depends on the acceptability and perceived legitimacy of using technologies that log interactions between individuals to build public health capacity. We report on six online deliberative workshops convened in New South Wales to consider the appropriateness of using the COVIDSafe app to (...) enhance Australian contact tracing systems. All groups took the position (by majority) that the protections enacted in the app design and supporting legislation were appropriate. This support is contingent on several system attributes including: the voluntariness of the COVIDSafe app; that the system relies on proximity rather than location tracking; and, that data access is restricted to local public health practitioners undertaking contact tracing. Despite sustained scepticism in media coverage, there was an underlying willingness to trust Australian governing institutions such that in principle acceptance of the new contact tracing technology was easy to obtain. However, tensions between the need to prove system effectiveness through operational transparency and requirements for privacy protections could be limiting public uptake. Our study shows that informed citizens are willing to trade their privacy for common goods such as COVID-19 suppression. But low case numbers and cautionary public discourses can make trustworthiness difficult to establish because some will only do so when it can be demonstrated that the benefits justify the costs to individuals.

Objective: To systematically analyze the effectiveness of technology-based interventions for reducing loneliness in older adults.Methods: We searched relevant electronic databases from inception to April 2021, which included Cochrane Library, PubMed, Web of Science, SpringerLink, EMBASE, CNKI, and Wanfang. The following criteria were used: study design—randomized controlled trial designs, people—older adults, intervention—technology-based interventions in which a core component involved the use of technology to reduce loneliness in older adults; and outcome—reduction of loneliness level in terms of rating scale (...) scores. Two reviewers independently identified eligible studies, extracted data, and assessed the risk of bias in the included studies. A third reviewer resolved any conflicts. The Cochrane Collaboration's bias assessment tool was used to evaluate the risk of bias for the included studies, and Review Manager 5.4 software was used for the meta-analysis. A random effects model was adopted to measure estimates of loneliness reduction, and standard mean differences with a 95% confidence interval were calculated for each intervention-control contrast, and the I2 statistic was applied to examine heterogeneity.Results: A total of 391 participants from six RCTs were included in the review. Of these, three studies were rated as low-quality, and the remaining three were rated as moderate-quality studies. The meta-analysis showed that the evidence regarding the effects on loneliness of technology-based interventions compared with control groups was uncertain, and suggested that technology-based interventions resulted in little to no difference in loneliness reduction compared to control groups. Two types of technology-based interventions were identified: smartphone-based video calls and computer-based training with Internet usage. The subgroup analysis found low-quality evidence to support the effectiveness of both intervention types.Conclusions: We found no current evidence to support that technology-based interventions were effective compared to different control conditions in reducing loneliness in older adults. This suggests that more research is needed to investigate the effects of technology-based interventions on loneliness in older adults. (shrink)

Acclaimed throughout the world as a philosopher of liberation and revolution, Herbert Marcuse is one of the most influential thinkers of the twentieth century. His penetrating critiques of the ways modern technology produces forms of society and culture with oppressive modes of social control indicate his enduring significance in the contemporary moment. This collection of unpublished or uncollected essays, unfinished manuscripts, and correspondence between 1942 and 1951, provides Marcuse's exemplary attempts to link theory with practice, and develops ideas that (...) can be used to grasp and transform existing social reality. These papers vividly chronicle Marcuse's increasing, yet reluctant estrangement from Max Horkeimer, director of the Institute for Social Research and his years as an analyst with various U.S. government agencies. Marcuse's later attempts to link theory and practice in the 1960s and 1970s in regard to the New Left, National Liberation Movements and other new social movements were grounded in his work from the 1940s. As the 1940s witnessed the rise to global prominence of German fascism and its defeat in World War Two, and the emergence of the Cold War, Marcuse strived to preserve the radical vision of his youth during a difficult historical period while many turned toward more conservative positions. Precisely the sort of broad theoretical and political theorizing that Marcuse undertook througout his life is needed today to analyze the momentous changes that we are currently undergoing. Excerpt: Personal history is interwoven with intellectual and political events in these papers. We debated whether letters belonged here: whether some should be published at all. My father had a deep sense of personal privacy, both as a character trait and as a political expression of resistance to the commodification of the private. Yet the letters contain substantive discussions also. We could have edited out, expurgated some of the material. While not publishing every letter my father wrote, our selection was based on interest, and every letter that is included is included in full. That decision was in part painful for me personally. The juxtaposition of the letters to Horkeimer and the exchange with Heidegger highlights the point. --from the Foreword by Peter Marcuse. (shrink)

The United States Environmental Protection Agency has begun to encourage innovative market-based approaches to address nonpoint source water pollution. These water quality trading programs have the potential to achieve environmental standards at a lower overall cost. Two fundamental questions must be answered before these benefits can be realized: How will trades between point and nonpoint sources be monitored and enforced? and, How will nonpoint sources be included within a trading market? ;Point-nonpoint source trading can be accommodated through either a (...) class='Hi'>technology-based or performance-based approach. The technology-based approach accommodates trading through the use of a proxy for unobservable, individual nonpoint source emission reductions. While trading ratios can effectively deal with the uncertainty associated with using a proxy for actual abatement, they are inefficient and ineffective for dealing with problems of hidden action. The alternative use of performance-based trading approaches requires the use of team contracts that provide individual incentives linked to the performance of the entire group. Such contracts must be designed to overcome both adverse selection and moral hazard problems. Performance-based approaches promise efficiency gains in terms of reducing the problems of asymmetric information, and by introducing flexibility into the choice of nonpoint source abatement technologies and practices. ;Nonpoint sources are exempted from direct regulation under the polluter-pays-principle. As a result, their participation in trading markets is voluntary, thus preventing a baseline cap on pre-trade emissions. To determine whether this arrangement should be changed, we must ask if there something that morally prohibits the direct regulation of nonpoint sources of pollution. While a morally relevant distinction can be made between point and nonpoint sources of emission based on differences in the ability to observe individual emission levels, this relevance is limited to the case of performance-based policy instruments. The moral legitimacy of applying the polluter-pays-principle to nonpoint sources of pollution must be made on a case by case basis, as it is dependent upon existing social, economic, and other practical factors. However, it can be stated that there is no general moral barrier to prohibit the application of the polluter-pays-principle to nonpoint sources of pollution. (shrink)

Earthquake is a kind of natural disaster, which will have a great impact on the building structure. In the vibration control field of building structures, the timeliness of system stability is extremely important. In traditional control methods, the timeliness is not paid enough attention for systems with uncertain seismic waves. For setting this problem, fuzzy adaptive compensation control for uncertain building structural systems by sliding-mode technology is proposed. It is combined with fuzzy adaptive control and sliding-mode control to ensure (...) that the system can be stable with satisfied timeliness. Also, saturation function is used to ensure the feasible physical implementation of the control system. Compared with the traditional LQR control, the simulation results showed that the proposed method can make the system reach a stable state with rapid convergence performance and has a feasible physical implementation.

There is growing interest in teaching computational thinking to preschool children given evidence that they are able to understand and use CT concepts. One of the concepts that is central in CT definitions, is the concept of control structures, but it is not clear which tools and activities are successful in teaching it to young learners. This work aims at providing a comprehensive overview of tools that enable preschool children to build programs that include control structures, and analyzing empirical evidence (...) of the usage of these tools to teach control structures to children between 3 and 6. It consists of three parts: systematic literature review to identify tools to teach CT to young children, analysis of tools characteristics and the possibilities that they offer to express control structures, and SLR to identify empirical evidence of successful teaching of control structures to young children using relevant tools. This work provides an understanding of the current state of the art and identifies areas that require future exploration. (shrink)
