Background: The practice of clinical supervision is considered an effective procedure to achieve a variety of professional outcomes for supervisees. Supervisory alliance mediates many of the learning outcomes thought important for effective supervision. Therefore, it is important to identity supervisor characteristics that relate to the capacity to develop a positive supervisory alliance and achieve supervision outcome. Aim: Supervisor interpersonal skill was investigated as a characteristic involved with both supervisee assessment of supervisory alliance and learning outcomes of supervision. Method: Forty supervisors completed assessments for interpersonal skill and provided 8 sessions of supervision to 50 supervisees. Supervisees completed assessments for supervisory alliance and supervision evaluation. Findings: Supervisor interpersonal skill predicted supervisee rated supervisory alliance and supervision outcome. Implications: Supervisor interpersonal skill is important for the capacity to develop a positive supervisory alliance and manage the learning environment of supervision. 相似文献

This paper uses wealth attainment as an indicator of economic integration and assesses how educational–occupational mismatch (i.e., over/underqualification) and race/ethnicity affect the wealth attainment of a sample of legal permanent residents in the USA. Using data from the New Immigrant Survey, this paper finds that overqualification is positively associated with wealth attainment, but below the rate for adequately qualified workers in the same occupation. Underqualified immigrants are associated with a pattern of wealth attainment that is equivalent to the adequately qualified. Racial/ethnic wealth inequality among legal permanent residents generally reflects the well-documented pattern among the U.S. native-born. This paper concludes with a discussion that places these results alongside previous research that examines the relationship between educational–occupational mismatch and income among immigrants. 相似文献

Epidemiological investigations have revealed increases in the prevalence of sedentary behaviors in industrialized societies. However, the implications of those lifestyle choices and related cardiorespiratory fitness levels for memory function are not well-understood. To determine the extent to which cardiorespiratory fitness relates to the integrity of multiple memory systems, a cross-sectional sample of young adults were tested over the course of 3 days in areas related to implicit memory, working memory, long-term memory, and aerobic fitness. Findings revealed an association between aerobic fitness and memory function such that individuals with lower cardiorespiratory fitness exhibited poorer implicit memory performance and poorer long-term memory retention. These data indicate that cardiorespiratory fitness may be important for the optimal function of neural networks underlying these memory systems. 相似文献

Given the importance of lexical frequency for psycholinguistic research and the lack of comprehensive frequency data for sign languages, we collected subjective estimates of lexical frequency for 432 signs in American Sign Language (ASL). Our participants were 59 deaf signers who first began to acquire ASL at ages ranging from birth to 14 years old and who had a minimum of 10 years of experience. Subjective frequency estimates were made on a scale ranging from 1 = rarely see the sign to 7 = always see the sign. The mean subjective frequency ratings for individual signs did not vary in relation to age of sign language exposure (AoLE), chronological age, or length of ASL experience. Nor did AoLE show significant effects on the response times (RTs) for making the ratings. However, RTs were highly correlated with mean frequency ratings. These results suggest that the distributions of subjective lexical frequencies are consistent across signers with varying AoLEs. The implications for research practice are that subjective frequency ratings from random samples of highly experienced deaf signers can provide a reasonable measure of lexical control in sign language experiments. The Appendix gives the mean and median subjective frequency ratings and the mean and median log(RT) of the ASL signs for the entire sample; the supplemental material gives these measures for the three AoLE groups: native, early, and late. 相似文献

By definition, multiple regression (MR) considers more than one predictor variable, and each variable’s beta will depend on both its correlation with the criterion and its correlation with the other predictor(s). Despite ad nauseam coverage of this characteristic in organizational psychology and statistical texts, researchers’ applications of MR in bivariate hypothesis testing has been the subject of recent and renewed interest. Accordingly, we conducted a targeted survey of the literature by coding articles, covering a five-year span from two top-tier organizational journals, that employed MR for testing bivariate relations. The results suggest that MR coefficients, rather than correlation coefficients, were most common for testing hypotheses of bivariate relations, yet supporting theoretical rationales were rarely offered. Regarding the potential impact on scientific advancement, in almost half of the articles reviewed (44 %), at least one conclusion of each study (i.e., that the hypothesis was or was not supported) would have been different, depending on the author’s use of correlation or beta to test the bivariate hypothesis. It follows that inappropriate decisions to interpret the correlation versus the beta will affect the accumulation of consistent and replicable scientific evidence. We conclude with recommendations for improving bivariate hypothesis testing. 相似文献

Plagiarism by college and university faculty members has become a growing issue and concern in academia. This paper presents a case study of an extreme and clear case of such plagiarism. Yet an analysis of the legal and ethical contexts of such plagiarism, and the specific chronicle of this case, illustrate the complexities and difficulties in dealing with such situations. Implications for researchers, for colleges and universities, and for academic publishers and journals are offered. 相似文献

Previous research has suggested that gambling as an escape is strongly related to disordered gambling. The present study tested whether factors related to disordered gambling were predictive of endorsing gambling as an escape. Three hundred eleven adults from the United States completed several measures of gambling and questionnaires on alcohol expectancies, emotion-regulation strategies, social-adjustment level, and sensation seeking. Consistent with previous research, endorsing gambling as an escape was strongly associated with reporting of gambling problems. Drinking as a coping mechanism and several emotion-regulation strategies were significant predictors of endorsing gambling as an escape. However, levels of social adjustment and sensation seeking were not predictive of gambling as an escape. The present results suggest that escape may be a higher-order factor that links substance abuse and disordered gambling. Likewise, they suggest that endorsing gambling as an escape is rooted in affect. As such, the results are informative to both researchers and practitioners. 相似文献

Infants born very preterm are at risk of developmental and behavioural problems and their parents are at risk of psychological distress and compromised parenting. This study has two key aims: (1) to identify, from the parents’ own perspective, the unique aspects of parenting an infant born very preterm and (2) to assess parent preferences for support including opinions of a new, tailored parenting intervention, Prem Baby Positive Parenting Program (Triple P). A qualitative approach was taken with focus groups of 18 parents of infants born preterm and a thematic analysis conducted. Parents identified several unique aspects of parenting an infant born preterm including: difficulty coping with the stress of hospitalisation; institutionalisation to the hospital environment; a lack of preparation for the transition to parenthood; grief; isolation; getting into “bad parenting habits” of overnurturance and a lack of certainty about developmental expectations. Parents preferred parenting support that is tailored to parents of infants born preterm, has flexible delivery, enhances coping skills and the spousal relationship and is sensitive to the emotional context of parenting an infant born preterm. Understanding the experiences and the preferences of parents of infants born preterm is an important step in tailoring parenting interventions to fit their needs. 相似文献

Explanations for the cognitive basis of the Müller-Lyer illusion are still
frustratingly mixed. To date, Day’s (1989)
theory of perceptual compromise has received little empirical attention. In this
study, we examine the merit of Day’s hypothesis for the Müller-Lyer illusion by
biasing participants toward global or local visual processing through exposure
to Navon (1977) stimuli, which are known
to alter processing level preference for a short time. Participants
(N = 306) were randomly allocated to global, local, or
control conditions. Those in global or local conditions were exposed to Navon
stimuli for 5 min and participants were required to report on the global or
local stimulus features, respectively. Subsequently, participants completed a
computerized Müller-Lyer experiment where they adjusted the length of a line to
match an illusory-figure. The illusion was significantly stronger for
participants with a global bias, and significantly weaker for those with a local
bias, compared with the control condition. These findings provide empirical
support for Day’s “conflicting cues” theory of perceptual compromise in the
Müller-Lyer illusion. 相似文献
