Do brief personalized feedback interventions work for mandated students or is it just getting caught that works?

Studies evaluating the efficacy of brief interventions with mandated college students have reported declines in drinking from baseline to short-term follow-up regardless of intervention condition. A key question is whether these observed changes are due to the intervention or to the incident and/or reprimand. This study evaluates a brief personalized feedback intervention (PFI) for students (N = 230) who were referred to a student assistance program because of infractions of university rules regarding substance use to determine whether observed changes in substance use are attributable to the intervention. Half the students received immediate feedback (at baseline and after the 2-month follow-up), and half received delayed feedback (only after the 2-month follow-up). Students in both conditions generally reduced their drinking and alcohol-related problems from baseline to the 2-month follow-up and from the 2-month to the 7-month follow-up; however, there were no significant between-group differences at either follow-up. Therefore, it appears that the incident and/or reprimand are important instigators of mandated student change and that written PFIs do not enhance these effects on a short-term basis but may on a longer term basis.     

Proposing and testing the contextual gender influence theory: An examination of gender influence types on trust of computer agents

The purpose of this research is to examine gender-based determinants of consumer trust towards computer agents. Employing multiple literatures, we propose a contextual gender influence theory (CGIT) which has direct bearing on trust in online exchange relationships. A set of studies is presented that begin to demonstrate how the effects of gender identity on human-to-computer interaction are not the same for person-to-person interaction. Indeed, employing both gaming and shopping exchange environments, the results reveal that while biological gender identity appears in a person-to-person interaction as concerns trust, psychological gender identity (specifically femininity) and not biological gender identity, influences relationship trust online.     

Delinquent peer affiliation and conduct problems: A twin study

Many putative environmental risks correlate with individuals' genotypes. The association between delinquent peer affiliation and conduct problems may occur because of shared genetic liability. Five hundred fifty three monozygotic and 558 dizygotic twin pairs, aged 11 to 18 years, were assessed for delinquent peer affiliation and conduct problems. The authors investigated whether genes contribute to both delinquent peer affiliation and the correlation between delinquent peer affiliations and conduct problems. Delinquent peer affiliation was influenced by genetic, shared environmental, and nonshared environmental factors; genetic factors also contributed to the correlation between delinquent peer affiliations and conduct problems, providing evidence for genotype-environment correlation. The magnitude of the genetic variance of conduct problems was contextually dependent on levels of delinquent peer affiliation and was greater at higher levels of delinquent peer affiliation.     

LTP induction modifies functional relationship among hippocampal neurons

To obtain evidence linking long-term potentiation (LTP) and memory, we examined whether LTP induction modifies functional relationship among neurons in the rat hippocampus. In contrast to neurons in low-frequency stimulated or AP5-treated slices, LTP induction altered 'functional connectivity,' as defined by the degree of synchronous firing, among simultaneously recorded neurons in the CA3 region. Interestingly, functional connectivity changed bidirectionally so that the total sum of functional connectivity remained constant. These results demonstrate LTP-induced changes in neuronal functional connectivity and suggest the existence of a normalization mechanism for the total sum of functional connectivity.     

The Relationship of Coworker Incivility to Job Performance and the Moderating Role of Self-Efficacy and Compassion at Work: The Job Demands-Resources (JD-R) Approach

Purpose

This study examined the relationship between coworker incivility and job performance via emotional exhaustion, and the moderating effect of employee self-efficacy and compassion at work on the relationship.

Design/Methodology/Approach

Drawing on the Job Demands-Resources (JD-R) model, we hypothesized an indirect relationship between coworker incivility and job performance through emotional exhaustion. Also, we predicted that the positive relationship between coworker incivility and emotional exhaustion would be weaker for employees with high self-efficacy and compassion experience at work. Surveys were gathered at two time points, 3 months apart, from 217 frontline employees of a five-star hotel in South Korea.

Findings

The results indicated that coworker incivility was negatively related to job performance and that the link was fully mediated by emotional exhaustion. Employees’ self-efficacy buffered the negative outcomes of coworker incivility, whereas experienced compassion at work did not moderate the relationship between coworker incivility and emotional exhaustion.

Implications

This study advances understanding of the negative consequences of coworker incivility and the ways to attenuate such negative effects. We suggested emotional exhaustion as a key psychological mechanism and revealed self-efficacy belief as a boundary condition related to coworker incivility.

Originality/Value

With a focus on emotional exhaustion, this study addresses the call for a better understanding of the psychological mechanism involved in workplace incivility. Also, we discovered the role that personal resources play in mitigating the negative effects of coworker incivility. Finally, we extend the literature by theorizing the boundary conditions of coworker incivility using the JD-R approach.

     

Structural Determinist Aspects of Depression in Freud's “Mourning and Melancholia”

This article examines Freud's theory of depression based on his paper “Mourning and Melancholia” from the structural determinist paradigm. The reality of depression lies in the underlying structure of the mind in which Freud's libidinal drives and topographical structure of mind bring forth conflicts in relation to an object. Freud delves into the fundamental causes of depression and points out that loss of object, regression of libido into the ego, and ambivalence cause hidden conflicts, which manifest themselves as depressive symptoms and feelings. William Styron's Darkness Visible is used to illustrate its relevance to the structural determinist aspects of Freud's psychoanalytic theory of depression.     

Acculturation, communication patterns, and self-esteem among Asian and Caucasian American adolescents

This study examined level of acculturation, openness in communication with parents, peer interaction, and self-esteem in two ethnic groups-Asian and Caucasian American adolescents who grew up in the same neighborhood. The findings provide evidence of significant ethnic differences in behavioral patterns, peer networks, family contexts, and levels of self-esteem. In general, Asian adolescents expressed more difficulty discussing problems with their parents when compared to their Caucasian counterparts. Further, self-esteem was found to be significantly lower among Asians than Caucasians. Implications for the provision of mental health services are discussed.     

Stress effects in the hippocampus: synaptic plasticity and memory

It is now well-documented that exposures to uncontrollable (inescapable and unpredictable) stress in adulthood can have profound effects on brain and behavior. Converging lines of evidence from human and animal studies indicate that stress interferes with subsequent performances on a variety of hippocampal-dependent memory tasks. Animal studies further revealed that stress impedes ensuing induction of long-term potentiation (LTP) in the hippocampus. Because the hippocampus is important for key aspects of memory formation and because LTP has qualities congruent to an information storage mechanism, it is hypothesized that stress-induced modifications in hippocampal plasticity contribute to memory impairments associated with stress. Recent studies provide evidence that the amygdala, a structure important in stress- and emotion-related behaviors, plays a necessary role in the emergence of stress-associated changes in hippocampal LTP and memory. Early life stress also alters hippocampal plasticity and memory in a manner largely consistent with effects of adult stress exposure. This review focuses on endocrine-system-level mechanisms of stress effects in the hippocampus, and how stress, by altering the property of hippocampal plasticity, can subsequently influence hippocampal memory.     

Testing hypotheses regarding the causes of comorbidity: examining the underlying deficits of comorbid disorders

The authors examined the validity of a method commonly used to test alternative hypotheses regarding the causes of comorbidity: the examination of underlying deficits of comorbid disorders. The authors simulated data in which the true causes of comorbidity were known, then compared the patterns of underlying deficits of the comorbid disorders found in the simulated data with the predicted results. The method of examining the underlying deficits of comorbid disorders could distinguish between several comorbidity models, including those that could not be distinguished well using other methods. The ability to distinguish the correct model decreased as the sample size and the correlation between the underlying deficits and the symptom scores decreased, suggesting that the issue of power should be considered carefully.
