The purpose of this study was to develop and compare tests of independent groups' slopes for non-normal distributions and heteroscedastic variances, including slope tests based on least squares, Theil-Sen, and trimmed estimation approaches. A slope test based on jackknife standard error estimates is proposed that can utilize each of the traditional estimation methods while also addressing problematic aspects of methods' standard error estimates. Simulations demonstrate that the proposed jackknife-based slope tests can improve standard error estimation, Type I error, and power relative to the traditional slope tests. 相似文献

Philosophers have nothing to lose, and much to gain, by paying close attention to developments in the natural sciences. This insight amounts to a case for a tempered, eclectic naturalism. But the case for naturalism is often overstated. We should not overestimate the heuristic benefits of close attention to scientists’ claims, nor should we give up on traditional “armchair” philosophical methods. We should not draw solely on the natural sciences (at the expense of the humanities) when seeking to enrich and discipline our philosophical theorising. Finally, philosophers should not shy away from criticising some scientists’ claims, at the same time as they learn from others. 相似文献

Many different instruments have been developed to assist in the assessment of risk for violence and other criminal behavior. However, there is limited evidence regarding how these instruments work in the 'real world'. Even less is known about how these instruments might work for assessing risk in jail diversion populations, whether in research or practice. To address these knowledge gaps, the present study examined the characteristics of risk assessments completed by program staff (n?=?10) on 96 mental health jail diversion clients (72 men and 24 women) using the Short-Term Assessment of Risk and Treatability (START). The findings provide preliminary support for the reliability and validity of START assessments completed in jail diversion programs, the first evidence of the transportability of START outside psychiatric settings, and further evidence regarding the reliability and validity of START assessments completed in the field. They additionally support the consideration of an eighth, general offending risk domain in START assessments. Copyright ? 2012 John Wiley & Sons, Ltd. 相似文献

Nostalgia fulfills pivotal functions for individuals, but lacks an empirically derived and comprehensive definition. We examined lay conceptions of nostalgia using a prototype approach. In Study 1, participants generated open-ended features of nostalgia, which were coded into categories. In Study 2, participants rated the centrality of these categories, which were subsequently classified as central (e.g., memories, relationships, happiness) or peripheral (e.g., daydreaming, regret, loneliness). Central (as compared with peripheral) features were more often recalled and falsely recognized (Study 3), were classified more quickly (Study 4), were judged to reflect more nostalgia in a vignette (Study 5), better characterized participants' own nostalgic (vs. ordinary) experiences (Study 6), and prompted higher levels of actual nostalgia and its intrapersonal benefits when used to trigger a personal memory, regardless of age (Study 7). These findings highlight that lay people view nostalgia as a self-relevant and social blended emotional and cognitive state, featuring a mixture of happiness and loss. The findings also aid understanding of nostalgia's functions and identify new methods for future research. 相似文献

Existing studies on task switching in Parkinson's disease (PD) patients have led to somewhat different results. In particular, it is unclear whether PD patients have a deficit in attentional control. In this study, we assessed task-switching abilities in samples of non-demented PD patients and elderly controls. We used a paradigm in which there was a random task sequence and the task was cued in every trial. This allowed the investigation of both task-set reconfiguration and task-set dissipation. In terms of the proportion of errors made, the patients showed increased switch cost and congruency effects. For reaction times, PD patients showed enlarged congruency effects on switch trials, specifically in the condition in which we used a short constant response-cue interval (RCI). Nevertheless, in a similar fashion to older controls, the patients showed reductions in reaction time switch cost from a short to a long cue-target interval (CTI) and from a short to a long RCI. While these latter findings, respectively, suggest unimpaired task preparation and task dissipation on correct trials in the PD patients, the overall results show that they have a deficit in biasing and selecting currently relevant task sets and more generally argue in favour of a failure of attentional control in PD. 相似文献

This study examines the relationships among ethics code awareness, perceived corporate ethical values, and organizational commitment. Three key findings emerged. First, those aware of the existence of an ethics code in their organizations perceived their organizations as having more ethical values than those not aware of an ethics code in their organizations. Second, respondents exhibited higher levels of organizational commitment when they were aware of an ethics code in their companies. Finally, the relationship between ethics code awareness and organizational commitment was fully mediated by perceptions of an organization’s ethical values. The results suggest that ethics codes may lead to higher levels of organizational commitment by increasing the belief that their organizations have strong ethical values, as long as the existence of ethics codes are adequately communicated. 相似文献

Abstract This paper describes the development of a simple paper-and-pencil test designed to measure satisfaction/dissatisfaction with 16 body parts. It is based on the body-cathexis scale of Secord and Jourard (1953) but takes only 2–3 minutes to complete. The factorial structure of the scale is described together with the three summative scales (“general,” “head parts” and “body parts” dissatisfaction) which are derived. The internal consistency of the scales was found to be acceptable. Significant positive correlations are also reported with the Body Shape Questionnaire (Cooper et al., 1987). The paper reports data for female comparison groups (college students, nursing students and female volunteers) and for samples of eating disorder patients and overweight subjects. The latter two groups report significantly higher body dissatisfaction than the comparison groups. Finally, it is argued that the scale is useful for work in health related fields and some current applications are briefly described. 相似文献

Although he does not provide a general analysis of argumentation, Aristotle is a highly influential source of modern argumentation theory. In his treatises the Topics, the Sophistical Refutations and the Rhetoric, Aristotle presents complementary aspects of a theory of sound arguments that are seen as the most effective means of persuasion. Aristotle’s central notion of a deductive argument (sullogismos) does not include references to an addressee, the situative context or non-verbal aspects of communication, and thus differs from some modern views on argumentation. A deductive argument in the Aristotelian sense is a sequence of intellectual steps where the conclusion follows of necessity from the premises. Aristotle does not relativize or relax this notion but takes other factors into account by providing supplementary theoretical elements. For example, he reflects on acceptable premises (endoxa), the adjustment of rhetorical arguments to the horizon of the audience, methods of finding premises on the basis of argumentative schemes (topoi), the use of non-argumentative means of persuasion, and a framework of implicit discourse rules. Many of these themes are, albeit under a different name, still discussed in modern argumentation theory. 相似文献

This paper defends an interpretation of the representational function of sensation in Kant's theory of empirical cognition. Against those who argue that sensations are ‘subjective representations’ and hence can only represent the sensory state of the subject, I argue that Kant appeals to different notions of subjectivity, and that the subjectivity of sensations is consistent with sensations representing external, spatial objects. Against those who claim that sensations cannot be representational at all, because sensations are not cognitively sophisticated enough to possess intentionality, I argue that Kant does not use the term ‘Vorstellung’ to refer to intentional mental states exclusively. Sensations do not possess their own intentionality, but they nevertheless perform a representational function in virtue of their role as the matter of empirical intuition. In empirical intuition, the sensory qualities given in sensation are combined with the representation of space to constitute the intuited appearance. The representational function of sensation consists in sensation being the medium out of which intuited appearances are constituted: the qualities of sensations stand in for what the understanding will judge (conceptualize) as material substance. 相似文献

Numerous researchers have highlighted the social determinants of athletes' attitude toward pain, yet little is known about the role of cognitive processes and emotions that are related to pain in sport endeavors. There is evidence, in a dot probe paradigm, that individuals with chronic pain selectively orient their attention toward pain-related stimuli, but no studies have differentiated between the two attentional processes of hypervigilance that are evident in athletes: facilitated detection of threat and difficulty in disengaging attention from threatening stimuli. In the present study using a dot probe paradigm, we examined whether professional rugby players (N=58) with high pain-related anxiety (HPA) would show an attentional bias for pain-related threat, and whether this hypervigilance would reflect difficulty disengaging from threat or facilitated detection of threat. Rugby players with HPA oriented their attention toward pain-related threat with a concomitant difficulty disengaging from threat. Difficulty disengaging from painful stimuli may increase anxiety, and thus be maladaptive in sport. This is the first study to identify pain-related anxiety as a vulnerability marker in athletes' attentional biases. 相似文献
