Many journals in the physical sciences require authors to submit assurances of compliance with human subjects and other research ethics standards. These requirements do not cover all disciplines equally, however. In this paper we report on the findings of a survey of perceptions of ethical and managerial problems from journal editors in political science and related disciplines. Our results show that few journals in political science require assurance statements common to journals for other scientific disciplines. We offer some reasons for this as well as some recommendations for implementing ethical assurance safeguards for political science. 相似文献

The present study investigates sleep, mood, and the proposed bidirectional relationship between the two in psychiatric disorders. Participants with interepisode bipolar disorder (n = 49), insomnia (n = 34), and no psychiatric history (n = 52) completed seven consecutive days of sleep diaries and mood measures. The interepisode bipolar and insomnia participants exhibited greater sleep disturbance than the healthy control individuals. Negative mood was equally heightened in both interepisode bipolar disorder and insomnia, and there were no differences between the three groups in positive mood. Total wake time was associated with next morning negative mood in bipolar disorder, whereas evening negative mood was associated with subsequent total wake time in both bipolar disorder and insomnia. Additionally, positive mood was associated with subsequent total wake time for the insomnia group. Results support the theory that disruptions in nighttime sleep and daytime mood may be mutually maintaining and suggest the potential importance of transdiagnostic or universal processes. 相似文献

Treatment integrity has cogent implications for intervention effectiveness. Understanding these implications is an important, but often neglected, undertaking in behavior analysis. This paper reviews current research on treatment integrity in applied behavior analysis. Specifically, we review research evaluating the relation between integrity failures and the efficacy of behavioral interventions. Avenues for future research are provided. 相似文献

A growing body of research has suggested that the experience of injustice, psychological contract breach, or unfairness can adversely impact an employee's health. We conducted a meta-analysis to examine the effects of unfairness perceptions on health, examining types of fairness and methodological characteristics as moderators. Results suggested that perceptions of unfairness were associated with indicators of physical and mental health. Furthermore, psychological contract breach contributed to the prediction of strain-related indicators of health above and beyond that accounted for by injustice alone. 相似文献

This longitudinal study sought to identify developmental changes in strategy use between 5 and 7 years of age when solving exact calculation problems. Four mathematics and reading achievement subtypes were examined at four time points. Five strategies were considered: finger counting, verbal counting, delayed retrieval, automatic retrieval, and derived fact retrieval. Results provided unique insights into children's strategic development in exact calculation at this early stage. Group analysis revealed relationships between mathematical and/or reading difficulties and strategy choice, shift, and adaptiveness. Use of derived fact retrieval by 7 years of age distinguished children with mathematical difficulties from other achievement subtypes. Analysis of individual differences revealed marked heterogeneity within all subtypes, suggesting (inter alia) no marked qualitative distinction between our two mathematical difficulty subtypes. 相似文献

Mental rotation is thought to underlie the increase in response times (RTs) for deciding whether rotated letters are normal
or mirrored versions. However, mental rotation predicts a linear increase in RTs, whereas the mirror/normal letter discrimination
task typically produces a curved function. Recently, Kung and Hamm suggested that this curved function results from a mixture
of trials in which mental rotation is employed and trials in which it is not. The mixture ratio may vary between individuals,
with some individuals relying more on mental rotation than others. There is no factor in the Kung and Hamm model that reflects
such individual differences. In the present study, we suggest that a possible exponent parameter could be added to the Kung
and Hamm model to capture individual differences in the mixture ratio. This exponent parameter appears to capture an individual
characteristic since the value obtained correlates between the mirror/normal letter task and a left/right object facing task.
The development of a quantity that represents the mixture ratio will aid further testing of processes involved in the visual
imagery system. 相似文献

In this paper, I argue that theists are extremely well-situated with respect to developing metaethical accounts that qualify
as ‘robust’ versions of moral realism. In the first part of the essay, a number of metaethical desiderata are identified.
In the second part, theistic strategies for accommodating those desiderata are explained and defended. The upshot is that,
contrary to the received philosophical wisdom, there are good theoretical reasons for theistic philosophers to seek to develop
metaethical accounts that ground moral facts in facts about God. 相似文献

Across four studies, people sat (or reported they would sit) closer to physically similar others. Study 1 revealed significant aggregation in seating patterns on two easily observed characteristics: glasses wearing and sex. Study 2 replicated this finding with a wider variety of physical traits: race, sex, glasses wearing, hair length, and hair color. The overall tendency for people to sit beside physically similar others remained significant when controlling for sex and race, suggesting people aggregate on physical dimensions other than broad social categories. Study 3 conceptually replicated these results in a laboratory setting. The more physically similar participants were to a confederate, the closer they sat before an anticipated interaction when controlling for sex, race, and attractiveness similarity. In Study 4, overall physical similarity and glasses wearing similarity predicted self-reported seating distance. These effects were mediated by perceived attitudinal similarity. Liking and inferred acceptance also received support as mediators for glasses wearing similarity. 相似文献

Converging findings suggest that depressed individuals exhibit disturbances in positive emotion. No study, however, has ascertained which specific positive emotions are implicated in depression. We report two studies that compare how depressive symptoms relate to distinct positive emotions at both trait and state levels of assessment. In Study 1 (N=185), we examined associations between depressive symptoms and three trait positive emotions (pride, happy, amusement). Study 2 compared experiential and autonomic reactivity to pride, happy, and amusement film stimuli between depressive (n=24; DS) and non-depressive (n=31; NDS) symptom groups. Results indicate that symptoms of depression were most strongly associated with decreased trait pride and decreased positive emotion experience to pride-eliciting films. Discussion focuses on the implications these findings have for understanding emotion deficits in depression as well as for the general study of positive emotion. 相似文献

Recently, Walter Sinott-Armstrong and Justin Snedegar have argued for a general contrastivist theory of reasons. According to the contrastivist account of reasons, all reasons claims should be understood as a relation with an additional place for a contrast class. For example, rather than X being a reason for A to P simpliciter, the contrastivist claims that X is a reason for A to P out of {P,Q,R…}. The main goal of this paper is to argue that the contrastivist account of reasons will be ill-fitted for accommodating certain features of moral reasons. In brief, the reason why the contrastivist analysis fails is that it cannot adequately allow for cases of morally correct whole-hearted action—cases where consideration of any alternate course of action would be misguided. But, if all consideration of alternate courses of action is misguided, then it is hard to see how one can set the relevant contrast class that is essential to the contrastivist view—any contrast class will seem out of place. In addition, I address some of the arguments that have been given in favor of the contrastivist account of reasons and argue that there are at least two ways that the non-contrastivist can respond to these arguments. 相似文献
