There is a longstanding definition of instantaneous velocity. It saysthat the velocity at t 0 of an object moving along a coordinate line is r if and only if the value of the first derivative of the object's position function at t 0 is r. The goal of this paper is to determine to what extent this definition successfully underpins a standard account of motion at an instant. Counterexamples proposed by Michael Tooley (1988) and also by John Bigelow and Robert Pargetter (1990) are reinforced and illuminated by considering the presence or absence of changes to the object's motion.  相似文献

The emergent consciousness and political activism within the transgender community has important implications for the field of counseling. In the current paradigm, the focus has shifted from using surgical and hormonal interventions and thereby enabling transgendered persons to “pass” within the traditional gender binary of society to affirming the unique identities of transgendered persons. To prepare counselors, counselor educators, and counseling supervisors for this important challenge, the authors describe the evolving nature of the transgender community, discuss mental health issues and counseling interventions for use with transgendered clients, and present a case study detailing the progression of counseling with 1 transgendered client.  相似文献

Marital estrangement, positive feelings toward spouses, and locus of control among a national sample of 323 female counselors who were either married or formerly married to alcohol‐abusing or to non‐alcohol‐abusing male partners were examined. Statistically significant differences between groups were found.  相似文献

Perceptions of a leader in a work environment is important from 2 perspectives: the leader themselves and more importantly the external observer. But what information does the observer use when making these judgments of leadership potential? Many studies on role congruity have demonstrated that gender stereotyping and perceived leadership ability is strongly tied to gender role incongruity. The role of facial appearance has been associated with leadership status and potential and becomes essentially relevant in military settings. Thus, the manner in which an individual’s face is perceived and evaluated may impact perceptions of his or her leadership ability and subsequent success. The present study seeks to extend research on how sex and gender characteristics of an individual’s face may possibly influence the perception of leadership abilities in a military service academy. Findings indicated that participants preferred individuals with gender congruent faces, which may reflect a preference for physical prowess and abilities.  相似文献

Many green products are costlier than their nongreen counterparts, for a variety of reasons. This “green premium” is a key challenge marketers face when targeting consumers with these green products. A potential solution to this issue is provided by signaling theory. According to the theory, green products can have a signaling benefit. This benefit acts as an incentive for consumers to pay a premium for environmentally friendly products that can even out their price disadvantage (the green signaling hypothesis). Previous studies have tested the green signaling hypothesis with hypothetical buying decisions. The research at hand tests the green signaling hypothesis with incentive‐compatible purchase decisions in a laboratory setting with student subjects. As predicted, subjects exhibit a higher willingness to pay for green products when the product choice (a nongreen product vs. a costlier green counterpart) is public rather than private. The results also suggest that green signalers are treated more favorably in social interactions. The main result is that a signaling benefit can even out moderate green premiums. One implication of this is the idea that marketers should design green products that are costlier than their nongreen counterparts in a way that renders them clearly recognizable as green. At the same time, marketers should avoid marketing everyday green products with a high green premium.  相似文献

Jacob Belzen spends the first two-thirds of his 2010 book doing two things: (1) developing a cogent critique of the presuppositions that underlie mainstream psychology, especially as regards the study of religion, and (2) promoting greater use of what he calls a “cultural psychology.” The last third presents a number of religious case studies, all from the Netherlands, that demonstrate the value of cultural psychology. Although Belzen emphasizes “embodiment” in these studies, his results suggest that religion is often a “performance” for particular audiences. Finally, the applicability of Belzen’s approach to religions outside the Western tradition is discussed.  相似文献

There is converging evidence that changing beliefs about an illness leads to positive recovery outcomes. However, cardiac misconceptions interventions have been investigated mainly in Angina or Coronary Heart Disease patients, and less in patients following Myocardial Infarction (MI). In these patients, cardiac misconceptions may play a role in the adjustment or lifestyle changes. This article reports a randomized controlled trial of an intervention designed to reduce the strength of misconceptions in patients after a first MI. The primary outcome was the degree of change in misconceptions and the secondary outcomes were: exercise, smoking status, return to work and mood (anxiety and depression). Patients in the intervention condition (n = 60) were compared with a control group (n = 67) receiving usual care. Both groups were evaluated at baseline and 4, 8 and 12 months after hospital discharge. There was a significant time-by-group interaction for the total score of cardiac misconceptions. Patients in the intervention group significantly decreased their total score of cardiac misconceptions at 4 months compared with the control group and this difference was sustained over time. Patients in the intervention group were also more likely to exercise at the follow-up period after MI than the control group. This intervention was effective in reducing the strength of cardiac misconceptions in MI patients and had a positive impact on health behaviour outcomes. These results support the importance of misconceptions in health behaviours and the utility of belief change interventions in promoting health in patients with Myocardial Infarction.  相似文献

This pioneering study in sub-Saharan African context examined the role played by religious strategies (religious coping, religious community support (RCS)) in the conjugal bereavement process and its outcomes depending on the expected or unexpected death. Based on cross-sectional approach, the study targeted Togolese bereaved spouses (N?=?162). The mean period of mourning was 112.52 months (SD?=?94.72). The results of a hierarchical regression revealed that RCS was positively associated with grief symptoms when the death was expected and, unsurprisingly, the negative religious coping predicted grief symptoms when the death was sudden and unexpected. Religious strategies would play a threefold role: providing refuge and comfort, regulating the bereavement distress and serving resources to give meaning to the loss of the beloved. Theoretical and clinical implications of these findings are discussed.  相似文献

Virtual prejudice   总被引:1,自引:0,他引:1  
According to recent theorizing in social psychology, social behavior is controlled not only by reflective, but also by impulsive systems. The latter are based on associative links that may influence behavior without intent. The current study examined how prejudiced implicit associations affect physiological and automatic behavioral responses. Our native Dutch participants were immersed in a virtual environment in which they encountered virtual persons (avatars) with either White or Moroccan facial features. In line with our predictions, participants maintained more distance and showed an increase in skin conductance level when approaching Moroccan avatars as opposed to White avatars. Participants’ implicit negative associations with Moroccans moderated both effects. Moreover, evidence was found that the relation between implicit prejudice and distance effects was fully mediated by skin conductance level effects. These data demonstrate how prejudiced implicit associations may unintentionally lead to impulsive discriminatory responses.  相似文献
