The attenuating effect of role overload on relationships linking self-efficacy and goal level to work performance

The reported research examines the moderating effects of role overload on the antecedents and consequences of self-efficacy and personal goal level in a longitudinal study conducted in an industrial selling context. The results indicate that role overload moderates the antecedent effect of perceived organizational resources on self-efficacy beliefs. They also show that role overload moderates the direct effects of both self-efficacy and goal level on performance, such that these relationships are positive when role overload is low but not significant when role overload is high. Further, the results reveal a pattern of moderated mediation, in which goal level mediates the indirect effect of self-efficacy on performance when role overload is low but not when it is high. Implications for theory and managerial practice are discussed.     

Empirically supported psychotherapies: comment on Westen, Novotny, and Thompson-Brenner (2004)

D. Westen, C. M. Novotny, and H. Thompson-Brenner (2004; see record 2004-15935-005) suggested that efforts to identify empirically supported treatments are misguided because they are based on assumptions that are not appropriate for some types of treatment and patients. The authors of this comment argue that Westen and colleagues are simply incorrect when they assert that empirically supported treatments require that psychopathology must be highly malleable, that treatments must be brief, or that the samples studied are unrepresentative of the kinds of patients typically encountered in clinical practice--comorbidity is common in many clinical trials. Randomized controlled trials remain the most powerful way to test notions of causal agency.     

Perceptual organization in schizophrenia spectrum disorders: empirical research and theoretical implications

The research into perceptual organization in schizophrenia spectrum disorders has found evidence for and against a perceptual organization deficit and has interpreted the data from within several different theoretical frameworks. A synthesis of this evidence, however, reveals that this body of work has produced reliable evidence for deficits in schizophrenia, as well as for the clinical, stimulus, and task parameters associated with normal and abnormal performance. Recent models of cognition have also advanced understanding of the underlying pathophysiological processes of perceptual organization dysfunction in schizophrenia spectrum disorders. These suggest that deficits in perceptual organization may be one manifestation of a wider disturbance in the integration of contextually related information across space and time.     

Provision of antiretroviral prophylaxis to child rape victims in South Africa: HIV status and delayed reporting

In a sample of 780 South African child victims of rape (girls under the age of 18 years; age M= 10.5 yr., SD=4.8), 10% did not qualify for antiretroviral prophylaxis because HIV status at presentation was positive and a further 34.1% did not qualify because the rape was reported more than 72 hours after the alleged offense. Regression analyses indicated that child rape victims who reported that they had been sexually active prior to the rape constitute a particularly high risk group for HIV infection and suggest primary and secondary prevention programs should be designed to decrease sexual activity among children and to encourage more immediate reporting of rape among younger children, children who are not sexually active, and children who are incestuously abused.     

Transitions in caregivers' use of paid home help: associations with stress appraisals and well-being

This study examines the associations between transitions in paid home care and stress appraisals and psychological well-being of family caregivers of dementia relatives. The sample consisted of 264 caregivers who completed up to 3 interviews during 1 year. Longitudinal analyses (i.e., generalized estimating equations) showed that the onset of paid home care was associated with increases in feelings of worry and strain and a worsening in positive affect. Ending paid home care was strongly associated with a decrease in depressive symptoms, whereas sustained use of paid home care was related to reduced overload. Several possible mechanisms for the complex relationship of paid home care and family caregivers' stress appraisals and well-being are discussed.     

Is obsessive-compulsive disorder a disturbance of security motivation? Comment on Szechtman and Woody (2004)

H. Szechtman and E. Woody (2004) proposed that obsessive-compulsive disorder (OCD) is caused by a malfunctioning brain security motivation system. In the current article, the authors' review of the model suggests that it is limited in the following ways: (a) It is built on a selective review of the empirical literature, (b) it offers no explanation for many important OCD phenomena, (c) it fails to distinguish OCD from generalized anxiety disorder, (d) some of the model's predictions are ambiguous or unfalsifiable, and (e) other predictions are refuted by previously published research. Models proposing that OCD is caused by a single dysfunctional mechanism, such as the security motivation model, have difficulty explaining the complexity and heterogeneity of OCD.     

论马一浮"六艺之学"视野中的易学研究

作为现代新儒家早期思想的代表人物,马一浮先生提出了以儒家"六艺之学"统摄天下诸学的主张.这是马先生的一个创举,体现着他对传统儒学有意识地改造和发扬.作为"六艺之学"的一个分支,易学研究在马一浮先生的学术研究中无疑具有着"本体论"地位和作用,它所体现的"心之本体",不仅是"六艺"所自出的本原,也是"六艺之学"共同的目的和归宿.     

The effects of directive and nondirective prompts on noncompliant vocal behavior exhibited by a child with autism

Results of an analogue functional analysis indicated that noncompliant vocal behavior exhibited by a young girl with autism was maintained by negative reinforcement. Follow-up analyses suggested that the immediate escape contingency assessed in the demand condition did not appear to maintain the behavior. Instead, noncompliant vocal behavior occurred in response to directive prompts. Nondirective prompts reduced noncompliant vocal behavior to near zero.     

Different emotional reactions to different groups: a sociofunctional threat-based approach to "prejudice"

The authors suggest that the traditional conception of prejudice--as a general attitude or evaluation--can problematically obscure the rich texturing of emotions that people feel toward different groups. Derived from a sociofunctional approach, the authors predicted that groups believed to pose qualitatively distinct threats to in-group resources or processes would evoke qualitatively distinct and functionally relevant emotional reactions. Participants' reactions to a range of social groups provided a data set unique in the scope of emotional reactions and threat beliefs explored. As predicted, different groups elicited different profiles of emotion and threat reactions, and this diversity was often masked by general measures of prejudice and threat. Moreover, threat and emotion profiles were associated with one another in the manner predicted: Specific classes of threat were linked to specific, functionally relevant emotions, and groups similar in the threat profiles they elicited were also similar in the emotion profiles they elicited.
