OUT OF UTOPIA:     
An important segment of writings on postindustrialization is distinctly utopian in stressing the greater mastery and control made possible by recent innovations in information technology. The utopian theme underscores the technical outcomes of innovations and highlights their benefits for ameliorating social problems. By contrast, our work suggests that many of the social problems in contemporary society are a consequence of recent innovations in information technology. We argue that postindustrial theorists are correct in stressing mastery over certain technical problems but incorrect in slighting the destabilizing effect innovations have on organizations and the markets in which these organizations participate. These destabilizing effects complicate organizational strategies by increasing market risk and uncertainty. Since most organizations are risk aversive, social problems are created as organizations externalize their costs and pass along risk to other, more dependent actors. Illustrations from two institutions, politics and the economy, indicate that many postindustrial innovations are associated with heightened competition as well as greater risk and uncertainty across the institutional order. We conclude that postindustrial technology introduces no net gain in man aging the complexities of the social world. Risk and control are both integral to technological innovation and constitute the paradox of postindustrialization.  相似文献

The present study was designed to explore further the effects of nonverbal behaviors and sex on compliance. Male and female subjects who had just found a dime in a phone booth were approached by a male or female experimenter and were asked to return the dime that the experimenter had supposedly just lost. In the Eye Contact condition, the experimenter gazed at the subject as the request was made, whereas in the No-Eye Contact condition he/she did not. In addition, the experimenter lightly touched half of the subjects while making his/her request, but did not touch the other half. Replicating previous findings, it was found that both eye contact (significantly) and touching (marginally) produced increased rates of compliance. Extending prior results, these effects were obtained for male experimenters. Furthermore, a Sex of experimenter times Sex of subject interaction effect was obtained, such that subjects were much more willing to comply with the request of an opposite, rather than same sex experimenter. Questionnaire data suggested that: 1) subjects were aware of the touch, but not of the eye contact variable, and 2) the requesters were perceived as much more attractive when they were of the opposite, rather than the same sex as the subjects.  相似文献

Academic freedom and the autonomy of academic institutions (their freedom from outside interference) are core values in contemporary academic life. This article outlines changes that have taken place in the last few decades that impact academic freedom and autonomy to at least some degree. These include the increasing catering by universities to stake-holders in the environment, increasing professionalization of university administrations, an evolving pattern of broadening authority over internal university decision-making, and an increasing attention to student (i.e. customer) needs. Two case studies -- one of recent decisions in the University of California system and the other at the University of Oslo -- illustrate the theoretical points in the article and point to the need to know a lot more about academic autonomy and academic freedom, especially in an environment of changing management practices and scarce resource bases for many institutions. The cases were selected because of the authors’ familiarity with them and are examples meant to illuminate some of the challenges and complexities inherent in the phenomena and to inspire further research on academic freedom and autonomy utilizing the instrumental and institutional perspectives from organization theory that are the core of our theoretical analysis.  相似文献

The extraordinary social and economic impact of the COVID-19 pandemic has generated many claims about the middle-range future—the period beginning in the late summer or early fall of 2020 and projected to last for some months or years. This paper surveys those assertions and seeks to explain the factors that led to them. Exploring questions about future claims can expand the scope of social problems theory.  相似文献

Objective: This pilot study pursued two aims. The first was to investigate the feasibility and acceptability of a Web-based acceptance and commitment therapy (ACT) intervention to reduce academic procrastination among university students. The second aim was to test the effectiveness of the intervention on procrastination and committed actions. Participants: The sample was comprised of Canadian university students (n?=?36) that participated in the intervention between September 2016 and April 2017. Methods: The study relied on a prepost research design. Results: The intervention appears feasible, acceptable, and valuable to students. A significant reduction in procrastination and a significant improvement in committed actions were found between pre and postintervention. The effect sizes for these results were medium. Conclusions: Results provide preliminary support for the feasibility and effectiveness of a Web-based ACT intervention for academic procrastination. Results also highlight some aspects that need to be improved for further development.  相似文献

This symposium describes collaborative research on neuroergonomics, technology, and cognition being conducted at George Mason University and the US Air Force Research Laboratory (AFRL) as part of the Center of Excellence in Neuroergonomics, Technology, and Cognition (CENTEC). Six presentations describe the latest developments in neuroergonomics research conducted by CENTEC scientists. The individual papers cover studies of: (1) adaptive learning systems; (2) neurobehavioral synchronicity during team performance; (3) genetics and individual differences in decision making; (4) vigilance and mindlessness; (5) interruptions and multi-tasking; and (6) development of a simulation capability that integrates measures across these domains and levels of analysis.  相似文献

To expand the scant research on sexual expectancies development among non–sexually active adolescents, we examined the relationship between adolescents' exposure to four socializing agents—mother/female guardian, father/male guardian, peers, and television programs with high sexual content—and their endorsement of four sexual expectancies: social benefit, pleasure, social risk, and health risk. Data are from Waves 2 and 3 of a three-wave annual longitudinal study conducted among California adolescents, the majority of whom were not sexually active (N = 914, 84%). Structural equation models were conducted to examine cross-sectional and longitudinal associations between the socializing agents and the sexual expectancies. Cross-sectional results indicate associations between peer sexual communication and social benefit, pleasure, and social risk expectancies. A positive association was found between exposure to music videos and social benefit expectancies, and a negative association was found between exposure to music videos and health risk expectancies. Longitudinal results suggest that communication with peers positively predicted pleasure expectancies and negatively predicted social risk expectancies. No other socializing agents were associated with any sexual expectancies. An invariance test found that significant correlations were similar across the different age groups. Results suggest that efforts to support positive sexual decision making among non–sexually active adolescents should target peer sexual communication.  相似文献

Organisations that develop demographic projections usually propose several variants with different demographic assumptions. Existing criteria for selecting a preferred projection are mostly based on retrospective comparisons with observations, and a prospective approach is needed. In this work, we use the mean–variance scaling (spatial variance function) of human population densities to select among alternative demographic projections. We test against observed and projected Norwegian county population density using two spatial variance functions, Taylor’s law (TL) and its quadratic generalisation, and compare each function’s parameters between the historical data and six demographic projections, at two different time scales (long term: 1978–2010 vs. 2011–2040; and short term: 2006–2010 vs. 2011–2015). We find that short-term projections selected by TL agree more accurately than the other projections with the recent county density data and reflect the current high rate of international migration to and from Norway. The variance function method implemented here provides an empirical test of an ex ante approach to evaluating short-term human population projections.  相似文献
