Abstract This study assessed the mental and physical health status and psychological problems related to the September 11th terrorist incidents among a representative sample of adults living near New York City, using continuously time-sampled data collected throughout 2001. Prevalence estimates for poor mental or physical health after September 11th (October through December) were comparable to those for the entire year of 2001 (i.e. approximately 33%). Psychological problems related to the terrorist incidents were reported by more than half of the respondents, and appeared to peak in prevalence approximately two to three months following the incidents, followed by a decline in the next month and subsequent year. Poor mental health, female gender, media re-exposure, and ongoing or increased alcohol use were risk factors for psychological problems, while older age (65+ years old) and being married were protective factors. Risk factors for poor physical and mental health or psychological problems were generally stable over the three-month period following September 11th, but some changes were identified consistent with stage models of post-disaster psychological adjustment. Implications are discussed for using continuous time-sampling as a strategy to research patterns of relatively acute stress-related sequelae of terrorism in populations whose members are affected despite primarily not having been at the disaster epicenter. 相似文献

This study explores the ethical attitudes, behaviors, and perceptions of a sampling of political science students in Taiwan. It investigates their intentions toward observing ethics in the area of digital rights, on topics such as the freedom of expression, freedom of association, equal access to information, confidentiality, security, and protection of intellectual property while using computers. Based on preliminary studies, a questionnaire was designed and distributed to 660 political science and public administration students throughout colleges in Taiwan. Data collected from 440 valid samples have been analyzed using structural equation modeling to test the three sets of hypotheses made by the researchers in the framework of the theory of planned behavior. Findings show attitude, subjective norm, and perceived behavior control of the respondents all have positive impacts on the personal observation of information ethics. In this regard, altruism, the secondary group, and the sense of security have greater influence than egoism, the primary group, and the consideration of self-efficacy. Implications of these findings and recommendations for cultivating computer ethics in Taiwan and elsewhere are discussed. 相似文献

Internal knowledge and visual cues about object's weight play an important role in grasping and lifting objects. It has been shown that both visual cues and internal knowledge might influence movement kinematics and force production depending on action goal (use vs. transport). However, there is little evidence about weight's influence on action planning as reflected by initiation time. In the present study we investigated this issue. In Experiment 1, participants had to grasp light and heavy objects (without moving them) to either use or transport them. In Experiment 2 we asked another group of participants to actually use or transport the same objects. We observed that initiation times were faster for heavy objects than for light objects in both the transport and use tasks, but only in Experiment 2. Thus, weight influenced the planning of use and transport actions, only when the end-goal of the action was really achieved. These data are incompatible with the hypothesis that only use actions are supported by stored object's representations. They rather suggest that in some circumstances, depending of the end-goal of the action and the physical constraints the planning of both use and transport actions are based on stored object representation. 相似文献

Abstract: This article argues that teachers of environmental ethics must more aggressively entertain questions of private property in their work and in their teaching. To make this case, it first introduces the three primary positions on property: occupation arguments, labor theory of value arguments, and efficiency arguments. It then contextualizes these arguments in light of the contemporary U.S. wise‐use movement, in an attempt to make sense of the concerns that motivate wise‐use activists, and also to demonstrate how intrinsic value arguments miss the mark. Finally, it offers some suggestions about further directions for environmental ethics, reasoning that there is a good deal of headway to be gained for environmental ethics by accepting that nature can be owned as property, but nevertheless engaging the idea of private property critically. 相似文献

It makes sense that the more information people share, the better they communicate. To evaluate the effect of knowledge overlap on the effectiveness of communication, participants played a communication game where the \"director\" identified objects to the \"addressee\". Pairs either shared information about most objects' names (high overlap), or about the minority of objects' names (low overlap). We found that high-overlap directors tended to use more names than low overlap directors. High overlap directors also used more names with objects whose names only they knew, thereby confusing their addressees more often than low-overlap directors. We conclude that while sharing more knowledge can be beneficial to communication overall, it can cause communication to be locally ineffective. Sharing more information reduces communication effectiveness precisely when there is an opportunity to inform-when people communicate information only they themselves know. 相似文献

This study evaluated a device that prevents drivers from shifting vehicles into gear for up to 8 s unless seat belts are buckled. Participants were 101 commercial drivers who operated vans, pickups, or other light trucks from the U.S. and Canada. The driver could escape or avoid the delay by fastening his or her seat belt before shifting out of park. Unbelted participants experienced either a constant delay (8 s) or a variable delay (M = 8 s). A 16‐s delay was introduced for those U.S. drivers who did not show significant improvement. Seat belt use increased from 48% to 67% (a 40% increase) for U.S. drivers and from 54% to 74% (a 37% increase) for Canadian drivers. The fixed delay was more effective for U.S. drivers than the variable delay, but there was no difference between these two delay schedules for Canadian drivers. After the driver fastened his or her seat belt, it tended to remain fastened for the duration of the trip. 相似文献

The purpose of this exploratory study is to investigate organizational‐level mechanisms in the Prevention Delivery System (PDS) and their influence on implementing comprehensive programming frameworks (e.g., Communities that Care‐CtC) as the innovation. The PDS is part of the Interactive Systems Framework for Dissemination and Implementation (ISF) and describes key characteristics of innovation implementation and dissemination. The study addresses two research questions: (1) What types of organizational characteristics are related to successful use of each of the programming processes (i.e., planning, implementation, evaluation, and sustainability) that are part of comprehensive programming frameworks?; and (2) What are the similarities and differences in the organizational patterns correlated with use of each of the programming processes? Surveys, interview data, and other documents designed to assess organizational characteristics and extent of use of a comprehensive programming framework over time, were collected from 8 Community boards and 23 provider agencies. These organizations were responsible for planning and delivering substance abuse prevention services as part of a statewide initiative in Ohio. Data were analyzed using Spearman rho (and rank‐biserial) correlations, with an emphasis on effect sizes. Results indicated that leadership, shared vision, process advocates, and technical assistance were common correlates of use across programming processes. However, the role played by these organizational variables differed for each programming process, pointing to complex interactions of the organizational infrastructure with other variables (i.e., characteristics of the innovation itself and external macro‐level factors). This exploratory study provides preliminary data on the organizational‐level mechanisms of the PDS and the complexity of their relationships with the other Systems in the Interactive Systems Framework. 相似文献

Abstract: In this article I examine three ways in which one might interpret Wittgenstein's Philosophical Investigations (PI). In a partial response to Hans‐Johann Glock's article in this journal, I suggest that since publication PI has, broadly speaking, been interpreted in three ways: doctrinal; elucidatory; or therapeutic. The doctrinal interpretation is shown to be, at best, difficult to sustain textually. The elucidatory (standard) interpretation, though seemingly closer to the text, is shown both to implicate Wittgenstein in some unfortunate philosophical commitments and to face a problem of “motivation.” I argue that, correctly understood, any attempt to elucidate in PI is undertaken only in pursuit of the therapeutic goal. I conclude by arguing that the therapeutic interpretation is the only interpretation that can adequately make sense of Wittgenstein's text as a whole and the metaphilosophical remarks in particular. Furthermore, it is the only interpretation that can demonstrate Wittgenstein's continued importance and relevance as a philosopher. 相似文献

This paper is the work of fi ve psychoanalysts who came together as a group in order to refl ect on their work as analysts. How are we analysts to identify the unconscious resistances that may sometimes hold us back from offering psychoanalysis to some patients? Do these resistances sometimes hamper the inner freedom that we require in order to maintain a psychoanalytic focus once that process is under way? How do we manage from time to time to overcome these resistances or, better, make use of them in order to develop our understanding of the unconscious dynamics that create the link between analyst and patient? The authors discuss these issues with particular reference to clinical situations taken from classic psychoanalytic treatment cases during which the analyst had to fi nd within him‐ or herself the audacity to be a psychoanalyst. Each clinical situation is different: preliminary interviews, in the course of the actual treatment, issues that emerge in the training of candidates. One of the signifi cant features of this group lies in the fact that the participants are at different stages in their development as psychoanalysts (student, associate member, full member, training analyst). This means that their experiences complement one another and encourage a discussion of issues such as how psychoanalysis can be passed on, and the relationship between supervisor and supervisee. 相似文献

Resiliency theory provides a conceptual framework for studying why some youth exposed to risk factors do not develop the negative behaviors they predict. The purpose of this study was to test compensatory and protective models of resiliency in a longitudinal sample of urban adolescents (80% African American). The data were from Years 1 (9th grade) and 4 (12th grade). The study examined effects of cumulative risk and promotive factors on adolescent polydrug use including alcohol, tobacco and marijuana. Cumulative measures of risk/promotive factors represented individual characteristics, peer influence, and parental/familial influences. After controlling for demographics, results of multiple regression of polydrug use support the compensatory model of resiliency both cross-sectionally and longitudinally. Promotive factors were also found to have compensatory effects on change in adolescent polydrug use. The protective model of resiliency evidenced cross-sectionally was not supported in longitudinal analysis. The findings support resiliency theory and the use of cumulative risk/promotive measures in resiliency research. Implications focused on utilizing multiple assets and resources in prevention programming are discussed. 相似文献
