This paper presents a test for determining significance of differences between means of samples which are drawn from positively skewed populations, more specifically, those having a Pearson Type III distribution function. The quantity 2npx

(wherep equals the mean squared divided by the variance andn is the number of cases in the sample), which distributes itself as Chi Square for 2np degrees of freedom, may be referred to the tables of Chi Square for testing hypotheses about the value of the true mean. For two independent samples, the larger mean divided by the smaller mean, which distributes itself asF for 2n

When a lower theoretical score limit (c) exists which is not zero, the quantity (Mean —c) should be used instead of the mean in all calculations. 相似文献

The mnemic neglect model predicts and accounts for selective memory for social feedback as a function of various feedback properties. At the heart of the model is the mnemic neglect effect (MNE), defined as inferior recall for self-threatening feedback compared to other kinds of feedback. The effect emerges both in mundane realism and minimal feedback settings. The effect is presumed to occur in the service of self-protection motivation. Mnemic neglect is pronounced when the feedback poses high levels of self-threat (i.e., can detect accurately one’s weakness), but is lost when self-threat is averted via a self-affirmation manipulation. Mnemic neglect is caused by self-threatening feedback being processed shallowly and in ways that separate it from stored (positive) self-knowledge. The emergence of mnemic neglect is qualified by situational moderators (extent to which one considers their self-conceptions modifiable, receives feedback from a close source, or is primed with improvement-related constructs) and individual differences moderators (anxiety, dysphoria, or defensive pessimism). Finally, the MNE is present in recall, but absent in recognition. Output interference cannot explain this disparity in results, but an inhibitory repression account (e.g., experiential avoidance) can: Repressors show enhanced mnemic neglect. The findings advance research on memory, motivation, and the self. 相似文献

Between 65 and 75 % of juvenile-justice involved (JJI) youth present with at least one behavioral health disorder. Many communities have developed diversion programs that provide behavioral health services to JJI youth, often in lieu of detention. A key component of successful diversion programming is accurate screening and assessment. The Ohio Scales, a validated instrument designed to track service effectiveness in clinical samples of youth, are now being used with juvenile justice populations. The purpose of this study is to validate the Ohio Scales in a JJI youth population (N = 2246). The population (ages 12–18) is derived from Ohio’s Behavioral Health Juvenile Justice Initiative, a diversion program for JJI youth with behavioral health issues. We conducted Confirmatory Factor Analyses (CFA) on all forms of the Ohio Scales (parent, youth and worker) to measure fit for one factor, four factor and four factor second order solutions. We also conducted an Exploratory Factor Analysis (EFA) on the Problem Severity factor in the youth form to determine the number of appropriate sub-factors. The EFA indicated that the Problem Severity factor should be broken into three hypothesized sub-factors: Externalizing, Internalizing and Delinquency. The CFA confirmed this solution. CFA results indicated the four factor second order solution fits superior to the other two solutions. Using the Ohio Scales Problem Severity measure as a three sub-factor measure may increase clinical applicability by allowing a clinician to specifically measure and target externalizing or internalizing issues during treatment. 相似文献

We study how job-related well-being (measured by Warr’s ‘Enthusiasm’ and ‘Contentment’ scales) altered through the Great Recession, and how this is related to changing job quality. Using nationally representative data for Britain, we find that job-related well-being was stable between 2001 and 2006, but then declined between 2006 and 2012. We report relevant changes in job quality. In modelling the determinants of job-related well-being, we confirm several previously-studied hypotheses and present some new findings: downsizing, work re-organisation, decreased choice, and linking pay to organisational performance each reduce well-being; indicators of skills challenge in jobs have more of a positive association with Enthusiasm than with Contentment, while effort has a more negative association with Contentment than with Enthusiasm. Our estimates are largely orthogonal to the effects of personality traits and demographic controls on well-being. Using a standard decomposition, we find that the 2006–2012 fall in job-related well-being is partly accounted for by accelerations in the pace of workplace change, rising job insecurity, increased effort and changing participation. 相似文献

This paper discusses the way in which postmodern emergence was used to assist a group of undergraduate students come to new understandings of research practice as they participated in a reflective component of an Undergraduate Research Summer School. Students were encouraged to ‘write the (researcher) self’ through a collaborative writing group based on the theoretical and pedagogical work of Somerville. Postmodern emergence highlights three stages of learning; firstly, assigning time for wondering, then a liminal space for becoming and finally an opportunity for generating new knowledge. This article is both the tangible product of this emergence reflective writing process and a recommendation about the capacity of undergraduate students to engage with their own professionalisation and meaning-making. 相似文献

This paper explores the impact that recent transformations in digital music technology (e.g. the increasing popularity of legal streaming platforms) have had on the consumer experience. Following 35 in‐depth qualitative interviews, we have identified four key segments of contemporary music consumers (steadfast pirates, ex‐downloaders, mixed tapes and the old schoolers [the disengaged]) based on a continuum of their preference for illegal music piracy. Examining key themes (e.g. morality, format, value and identity investment) to distinguish each segment, we contribute to a fragmented music piracy literature in particular through the identification of the “ex‐downloaders” and “mixed tape” segments. Previous literature has tended to frame music piracy in very simplistic terms, failing to acknowledge a large number of consumers who are conflicted about their actions and rationalise their piracy in complicated and inconsistent ways related to the broader industry and their own sense of identity as a music consumer. Additionally, the discussion of the ex‐downloader segment provides significant evidence that for a large number of consumers, a policy of participation, in the shape of providing superior alternatives for legal digital music consumption, can be much more beneficial in tackling the problem of piracy than previous strategies of policing and coercion. Managerial and future research implications are discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

A central feature of meaning in life is a consideration of more than oneself. We extend this logic to suggest that altruistically motivated prosociality – acting in ways that benefit others – is a self-transcending action that may provide meaning in life. Study 1 provided evidence of a relationship between self-reported prosocial behavior and meaning in life, even after statistically controlling for personality traits and self-esteem. Study 2 provided evidence that engaging in a prosocial action, via writing notes of gratitude, increased meaning in life. Study 3 provided evidence that individuals bolster perceptions of prosociality following threats to meaning. Study 4 suggested relationship satisfaction partially mediates the link between prosocial actions and meaning in life. These studies provide initial evidence that prosociality enhances meaning in life. 相似文献
