Human activity has significantly influenced energy flows in the landscape. Physical and geographical features of an area in the context of natural processes highlight their influence on the human lives in the affected regions of Slovakia. The paper aimed on the influence of the extraordinary flooding impact in June 2013 on the quality of life in Slovak rural regions. We have investigated the impact of the resulting damage on human activities in the rural municipality of Ch?aba. The case study of southern Slovakia can provide a more realistic view at regularly flooded areas in Slovak geographical conditions. The target of our research was to map and monitor the situation during the floods and shortly after them and to draw proposals leading to a more operative approach in the context of comprehensive flood protection in Slovakia. The added value of the research is a creation of such graphical supporting documents, which could be served as a basis for creating the plan of flood prevention management in rural territories, as a part of negative impacts of floods reduction on human activities.  相似文献

OBJECTIVES: The authors previously reported that individuals who rate their daily life as more demanding or less controllable by momentary electronic diary (ED) reports showed greater intima-medial thickness (IMT) by carotid ultrasonography. They now present prospective findings on this relation. DESIGN: Three hundred thirty-five healthy individuals (ages 50-70 at study onset) completed ongoing ratings of activity and mood over a 6-day period, using ED assessments. MAIN OUTCOME MEASURES: Mean bilateral carotid artery IMT was measured at baseline and 36 months later. RESULTS AND CONCLUSION: Mean ratings of high demand and low control were significantly associated with IMT progression among men but not among women. These associations were not explained by traditional risk factors or by measures of occupational stress. Effects were partially accounted for by elevated ambulatory heart rates among those with low ratings of control. These data support the utility of ED-based measures for examining psychosocial risks in the prediction of cardiovascular disease progression.  相似文献

A pilot study was conducted of a personalized feedback intervention for problem gamblers. Respondents (N = 61) were recruited from an ongoing gambling research study to take part in another study to help us “develop and evaluate self-help materials for gamblers.” Respondents were randomly assigned to receive a personalized feedback summary or to a waiting list control. At 3-month follow-up (80.3% follow-up rate, N = 49), after controlling for baseline demographic characteristics and gambling severity, respondents in the feedback condition displayed some evidence that they were spending less money on gambling than those in the control condition. Further, ratings of the usefulness of the feedback summary were positive and most recipients (96%) recommended that they be made available to other gamblers interested in evaluating or modifying their gambling. Given these promising pilot results, a full-scale evaluation of these personalized feedback materials would appear justified. An online version of the intervention is now also available at www.CheckYourGambling.net.  相似文献

This project explores the impact of Barack Obama’s presidential campaign and the resulting high levels of exposure to a positive, counter-stereotypic Black exemplar, on prejudice and stereotyping among non-Black participants. We found dramatically decreased levels of implicit anti-Black prejudice and stereotyping as compared with bias observed previously at the same institutions and in the literature. Providing some insight why the bias was reduced, Study 1 demonstrated that participants had positive Black exemplars come to mind or anticipated that other people have positive exemplars come to mind when they thought of Black people and this was associated with low levels of racial prejudice. Our second study revealed that participants who had qualities strongly associated with Obama as a political figure (e.g., president) activated when they were primed with “Black” had lower levels of implicit prejudice. These findings indicate that the extensive exposure to Obama resulted in a drop in implicit bias.  相似文献

While electronic reading devices are extremely popular, research is equivocal regarding their benefits for outcomes such as reader comprehension. Integrating literatures on reading medium comparisons and matching effects in persuasion, this research tested whether comprehension is maximized when the content of the material (e.g., whether it is traditional vs. modern) matches the medium (e.g., reading from a traditional book vs. digital e-reader). In Study 1, participants read a traditional- or modern-themed short story from either a book or an e-reader. Story comprehension was greater when participants read from the printed medium compared to the e-reader, an effect that was marginally moderated by story content, consistent with a matching effect. In Study 2, participants read a persuasive message that emphasized either a traditional versus modern solution to improving health in either a magazine format or on an iPad. Message comprehension was marginally greater among participants who read their message in a printed format. Participants’ interest in weight loss showed evidence of a matching effect – participants were more interested in losing weight when a modern solution to obesity article was presented on an iPad compared to a printed format. The results are applied to the study of reading and attitude change.  相似文献

At a time of acute danger, people commonly petition God for help for themselves or their loved ones; such as praying that an avalanche heading in one's direction be diverted, or that an organ donor be found for one's dying child. Such prayer seems natural and, indeed, for believers, reasonable and acceptable. It seems perverse to condemn such typical prayer, as wrong. But once we closely examine what is actually happening in such situations, we shall see that frequently prayer of this sort is morally problematic. I argue that such prayer ought to be seen as a form of action (rather than, say, mere hope), thereby needing to meet the higher moral standards that apply to actions; and that the assumption of the benevolence of the deity does not suffice to make such prayer legitimate.  相似文献
