Hugh Mellor has proposed what appears to be a new solution to the problem of intrinsic change ( Mellor 1998 ). Assuming endurantism and a B‐theoretic, nonpresentist view of time, facts are supposed to have only enduring things and atemporal properties (or relations) as constituents, but no times. The having of properties and relations is not relativised to times. Instead, the whole of a fact is conceived of as temporally localised. It will be argued that this interesting and novel proposal does not succeed as an account of change in the intrinsic properties of things. The basic difficulty is that the view still leads into contradiction, since it makes it incomprehensible how one and the same thing can have both a property and some incompatible property. The having of these incompatible properties is treated as two facts. But to add that these facts have certain temporal locations is of no help for avoiding the contradiction. 相似文献

This article analyses the different connotations of “normality” and “being natural,” bringing together the theoretical discussion
from both human medicine and veterinary medicine. We show how the interpretations of the concepts in the different areas could
be mutually fruitful. It appears that the conceptions of “natural” are more elaborate in veterinary medicine, and can be of
value to human medicine. In particular they can nuance and correct conceptions of nature in human medicine that may be too
idealistic. Correspondingly, the wide ranging conceptions of “normal” in human medicine may enrich conceptions in veterinary
medicine, where the discussions seem to be sparse. We do not argue that conceptions from veterinary medicine should be used in human medicine and vice versa, but only that it could be done and that it may well be fruitful. Moreover, there are overlaps between some notions of normal and natural, and further conceptual analysis on this
overlap is needed. 相似文献

In this article, we develop and meta-analytically test the relationship between job demands and resources and burnout, engagement, and safety outcomes in the workplace. In a meta-analysis of 203 independent samples (N = 186,440), we found support for a health impairment process and for a motivational process as mechanisms through which job demands and resources relate to safety outcomes. In particular, we found that job demands such as risks and hazards and complexity impair employees' health and positively relate to burnout. Likewise, we found support for job resources such as knowledge, autonomy, and a supportive environment motivating employees and positively relating to engagement. Job demands were found to hinder an employee with a negative relationship to engagement, whereas job resources were found to negatively relate to burnout. Finally, we found that burnout was negatively related to working safely but that engagement motivated employees and was positively related to working safely. Across industries, risks and hazards was the most consistent job demand and a supportive environment was the most consistent job resource in terms of explaining variance in burnout, engagement, and safety outcomes. The type of job demand that explained the most variance differed by industry, whereas a supportive environment remained consistent in explaining the most variance in all industries. 相似文献

Diseases often spread in hospitals because health care professionals fail to wash their hands. Research suggests that to increase health and safety behaviors, it is important to highlight the personal consequences for the actor. However, because people (and health care professionals in particular) tend to be overconfident about personal immunity, the most effective messages about hand hygiene may be those that highlight its consequences for other people. In two field experiments in a hospital, we compared the effectiveness of signs about hand hygiene that emphasized personal safety ("Hand hygiene prevents you from catching diseases") or patient safety ("Hand hygiene prevents patients from catching diseases"). We assessed hand hygiene by measuring the amount of soap and hand-sanitizing gel used from dispensers (Experiment 1) and conducting covert, independent observations of health care professionals' hand-hygiene behaviors (Experiment 2). Results showed that changing a single word in messages motivated meaningful changes in behavior: The hand hygiene of health care professionals increased significantly when they were reminded of the implications for patients but not when they were reminded of the implications for themselves. 相似文献

This study examined the effects of different emotion regulation strategies on the experience and expression of anger. Participants consisted of undergraduate students who endorsed at least a moderate level of state anger. As part of a laboratory experiment, they were instructed to reappraise (n = 24), suppress (n = 24), or accept (n = 25) their anger during a frustrating task. Reappraisal was more effective at reducing anger than attempts to suppress or accept it. Furthermore, participants in the reappraisal condition persisted significantly longer with the frustrating task than those who were instructed to suppress or accept their negative feelings. These findings suggest that reappraisal techniques are more effective than acceptance and suppression techniques for modulating the experience and expression of anger. 相似文献

We present an overview of research on how social experiences and hormonal responses affect individual variation in parental care of birds and mammals. The parental roles of prolactin and glucorticoids (corticosterone or cortisol) have many similarities in birds and in mammals. Prolactin may be involved in the initiation of parental interactions, with prolactin variation possibly explaining individual differences in parental decision-making. Glucocorticoid levels increase when parents have to work harder, with some individuals showing greater hormonal and behavioural responses than others. Testosterone interferes with paternal behaviour in birds, but its role is more complex and species-specific in male mammals. We examine these differences in an adaptive framework, where retaining flexibility of response has allowed individuals to respond differentially to social opportunities and environmental change. 相似文献

According to Antonia Barkes version of contextualism, epistemic contextualism, a context is defined by a method and its associated assumptions. The subject has to make the assumption that the method is adequate or reliable and that good working conditions hold in order to arrive at knowledge by employing the method. I will criticize Barkes claim that epistemic contextualism can provide a more satisfactory explanation or motivation for context shifts than conversational contextualism (in particular, David Lewiss contextualism). Two more points of criticizm will be presented, which are meant to show that epistemic contextualism presupposes epistemic internalism, and that (epistemic) contextualism leads to an implausible view about which parameters the special achievement that is constitutive of knowledge depends on. I suggest that, contra (epistemic) contextualism, knowledge is a more robust phenomenon that does not depend on whether anyone calls into question any assumptions or raises skeptical doubts in conversation or in his or her mind (as, for example, Fred Dretskes account says). I indicate how this can be reconciled with the phenomenon that knowledge attributions are somewhat unstable and seemingly context-dependent. 相似文献
