A study into the relationships between candidateself-monitoring ability, interviewer perceptions ofcandidate personality, and interviewer outcome decisionsin the context of actual graduate recruitment interviews (n = 130) is presented. Detailedpsychometric norm data is also reported on the Lennoxand Wolfe (1984) revised Self-Monitoring (RS-M) scale,together with the results of confirmatory factoranalyses into the factor structure of this measure. Itwas found that candidate self-monitoring ability wasonly moderately and nonsignificantly related tointerviewer outcome evaluations, and thatself-monitoring was generally uncorrelated with thepositiveness of recruiter impressions of candidatepersonality. Confirmatory factor analyses revealed thata two correlated factor structure for the RS-M scale, inaccordance with the original authors' formulation,provided the most parsimonious fit. Norm data for theRS-M scale is reported for this sample of Britishgraduates, including item statistics, item to subscale,item to scale correlations, and internal reliabilitycoefficients. Implications for future research intocandidate impression management, self-monitoring,interviewer decision making, and the practicalimplications arising from these findings arediscussed.  相似文献

This study tested the hypothesis that married psychiatric outpatients would have lower total health services expenditures than divorced or separated patients. Chart review of the 471 individuals attending an academic medical center outpatient psychiatric clinic during 1994 identified 131 married, 40 separated, and 93 divorced patients. Separated men had significantly higher average total charges ($16,890) than married ($5,279) or divorced ($5,539) men by one-way ANOVA (p < .05). The nonparametric Mann-Whitney test also showed that separated men had higher charges than married or divorced men. There were no differences between marital status groups for women.  相似文献

Research on conflict, power, and violence in families in the 2000s developed a promising focus on the interconnections between types of violence and between the experience of violence and locations in larger structures of power and inequality. I examine research on poly‐victimization, typologies of violence, dyadic research, and links between violence and inequalities of gender, race, class, and sexual orientation. Additionally, this review evaluates research on the connections between violence in families and other arenas of family study, including teen pregnancy, marriage formation, cohabitation, and divorce. The review concludes with a discussion of studies showing declines in rates of abuse within families in the 2000s.  相似文献

This study reviews the creation and testing of a model of Therapist Personal Agency during MFT training. A model including self-efficacy, trainee developmental level, supervisor working alliance, family of origin relationships, and psychological states was supported by data collected from a national sample of MFT students. The model supported by the data was consistent with much of the previous research regarding the correlates of therapist self-efficacy. Furthermore, the model accounted for 20% of the variance in therapist performance as measured by therapist reports of the working alliance. The results also highlighted the importance of attending to the relationships, interactions, and experiences that take place within the training environment and secondly, the added value that may accrue from focusing on the trainee's extended network of family relationships. A brief case example serves to illustrate the importance of tending to Therapist Personal Agency. In sum, this study provides preliminary support for holistic training methods that focus upon the whole person of the therapist.  相似文献

Plant-based stormwater management systems such as green roofs are typically composed exclusively of vascular plants. Yet, mosses have several desirable properties that could warrant their more widespread use in green roof applications. In natural systems mosses are important primary colonizers of bare ground, and their establishment improves water storage and provides numerous soil benefits including carbon and nitrogen sequestration. Additionally, mosses often facilitate the establishment and survival of vascular plants at otherwise environmentally harsh or stressful sites. Despite their potential value, few studies have investigated the functional performance of mosses on green roofs. In this study we evaluated the establishment success and potential stormwater performance of three candidate moss species. We also directly compared the runoff and thermal characteristics of replicate moss covered green roofs to vascular planted and bare roofs. Candidate mosses had high water holding capacities, storing 8–10 times their weight in water compared to only 1.3 times for typical green roof medium. Mock-up roof sections composed of mosses and medium had delayed and reduced runoff flows relative to medium only sections, although the magnitude of these effects varied with moss species. In field trials all three mosses survived a harsh rooftop environment with limited summer irrigation, although lateral growth after one year was minimal. Green roofs planted solely with Racomitrium canescens had between 12–24% higher stormwater retention than vascular or medium only roofs. Moss cover also ameliorated temperature fluctuations on green roofs. Hourly heating rates were buffered to a similar degree (less than half that of surface temperatures) 5 cm below the surface of both moss covered and medium only roofs. In contrast, cooling under the surface of the moss roof was nearly 6 times faster than under the medium only roof. These results demonstrate the potential for mosses to be valuable components of green roofs, either in combination with vascular plants or planted exclusively.  相似文献

In a recent Decision Sciences article, McMath (1990) developed the correction constants approach for eliminating the end-of-year bias in the present value of streams with subannual cash flows. A limitation of this approach is that it assumes subannual cash flows are level. In many types of businesses, subannual cash flows follow a predictable seasonal pattern and, consequently, a present value estimate based upon a level correction constant is biased. This article derives a general formula for determining correction constants for seasonal cash flow patterns, examines the direction and magnitude of the seasonal bias, and applies seasonal correction constants to a capital budgeting problem.  相似文献

Deposits held at Federal Reserve Banks are an essential input to the business activity of most depository institutions in the United States. Managing these deposits is an important and complex inventory problem for two reasons. First, Federal Reserve regulations require that depository institutions hold certain amounts of such deposits at the Federal Reserve Banks to satisfy statutory reserve requirements against customers' transaction accounts (demand deposits and other checkable deposits). Second, some inventory of such deposits is essential for banks to operate one of their core lines of business: furnishing payment services to households and firms. Because the Federal Reserve does not pay interest on such deposits used to satisfy statutory reserve requirements, banks seek to minimize their inventory of such deposits. In 1994, the banking industry introduced a new inventory management tool for such deposits, the retail deposit sweep program, which avoids the statutory requirement by reclassifying transaction deposits as savings deposits. This is an interesting inventory problem for fungible items, where the conversion process is reversible. We examine two methods for operating such sweeps programs within the limits of Federal Reserve regulations, and we develop a stochastic dynamic programming model to implement one such method, the threshold method.  相似文献

In the past decade nearly 20 Colorado communities have constructed kayak courses to provide recreational amenities and attract tourists. These projects were followed in some cases by applications for a new form of recreational water rights, which differs dramatically from traditional forms of water rights in Colorado. This paper investigates the role that citizens played in the legal and legislative battles that resulted in this policy change. Findings indicate that citizens demanded the construction of kayak courses across Colorado, to which local officials responded. Citizens generally were indifferent to water rights applications once kayak facilities were constructed, however. Government officials sought the water rights to protect their economic investment and their newfound tourist revenue.

ABSTRACT

Objective: This campaign sought to (a) increase awareness of sexual health and chlamydia testing; (b) motivate students, particularly sexually active men who do not pursue regular sexually transmitted infection (STI) testing, to get tested; and (c) improve the capacity of the student health center to provide free chlamydia testing and treatment for all students. Participants: Students enrolled at a 4-year public research university (N = 333). Methods: Collaborative partnerships formed the foundation of a campus marketing and testing campaign, with treatment for students testing positive for chlamydia. Results: A total of 333 students were tested over 5 consecutive Mondays, showing a chlamydia incidence of 9.6%. The incidence for females and males were 8.6% and 10.8%, respectively. Conclusions: The campaign was effective in reaching men, an at-risk population not traditionally emphasized in STI testing.  相似文献
