组织政治环境如何影响领导者公正准则遵从？

论文基于自我控制的强度模型,研究了组织政治环境作为情境因素影响领导者公正准则遵从的作用机制和边界条件。对来自某国有商业银行73位网点主任连续10个工作日的570个经验取样法的数据分析结果发现：(1)在个体内层次,领导者组织政治感知提高了自我耗竭,领导者职位任期削弱了该正向关系。(2)个体内层次自我耗竭对公正准则遵从的作用取决于个体间层次领导身份认同的程度：当领导身份认同较高时,二者关系为正;当领导身份认同较低时,二者关系为负。(3)当领导者职位任期较短且领导身份认同较高时,组织政治感知通过自我耗竭促进公正准则遵从;当职位任期较短且领导身份认同较低时,组织政治感知通过自我耗竭阻碍公正准则遵从。上述研究结论将公正准则遵从的前因研究从行为者中心视角拓展到情境中心视角,率先研究了组织政治感知的个体内变化及其影响,同时增进了对自我耗竭作用机制和边界条件的认识。     

ACHIEVING AND MAINTAINING COMPLIANCE WITH THE KETOGENIC DIET

The ketogenic diet, a treatment for intractable epilepsy, is rarely initiated because it requires strict compliance with a diet that is perceived to be unpalatable. In a case study of a 15-year-old girl with uncontrolled epilepsy, we used a stimulus-choice procedure to assess relative preferences of 33 foods from the diet and to develop two treatments based on Premack's principle. The results of a multielement analysis showed that both treatments increased dietary compliance. Compliance was maintained with generalization of treatment across settings, and was associated with a 40% reduction in seizures.     

Evaluating preference for and reinforcing efficacy of fruits and vegetables compared with salty and sweet foods

Children diagnosed with autism spectrum disorder are often more selective in their food preferences than their typically developing peers. Additionally, many preferred food selections have minimal nutritional value. We evaluated the preference for, and reinforcing efficacy of, fruits and vegetables compared with salty and sweet foods, which are often used as edible reinforcers. Multiple-stimulus preference assessments were conducted to identify preferred foods, and reinforcer assessments were conducted to determine the reinforcing efficacy of more preferred foods. Fruits and vegetables were sometimes preferred over salty or sweet foods and often functioned as reinforcers. Future research should incorporate fruits and vegetables into preference assessments when identifying putative reinforcers.     

Predatory aggression in the mink (Mustela vison): Roles of serotonin and food satiation

5-Hydroxytrypotophan at a dose of 50 mg/kg intraperitoneally (i.p.) sharply increased neural serotonin (5-HT) levels in mink and considerably inhibited that animal's predatory attack on rats. Intraperitoneal injection of 5-HT (10 and 20 mg/kg) did not influence such rat-killing. Neural levels of 5-HT or 5-hydroxyindoleacetic acid (5-HIAA) and subsequent aggression by the predator did not change to any great degree after ingestion of a single meal. Abundance of natural mink food for 3 days was associated with an increased level of 5-HIAA in the lateral hypothalamus and the amygdala as well as with an increased latency to attack and to kill rats. 5-HT seems to represent an endogenous factor that inhibits predatory attack by the mink; this effect appears to function through increased metabolism of 5-HT in some brain regions, which is evident after abundant intake of tryptophan with the natural diet.     

Predictors of Adherence to a Brief Behavioral Insomnia Intervention: Daily Process Analysis

Behavioral interventions for insomnia are effective in improving sleep, yet adherence is variable, and predictors of adherence have not been consistently replicated. The relationships between daily variations in state factors at the initiation of treatment and adherence have not been investigated. Using 2-week, self-report online logs, this study determined, among 53 college students with probable insomnia, the associations of pretreatment factors and daily factors during treatment on daily variations in adherence to one session of behavioral treatments for insomnia. These treatments included stimulus control therapy (SCT), sleep restriction therapy (SRT), and sleep hygiene (SH). Low self-efficacy was associated with poorer SCT and SH adherence. Participants with a “bed partner or pet” at least some of the time had better SCT adherence. Greater total sleep time and poorer sleep quality were associated with poor SCT and SRT adherence the following night. Greater sleep efficiency was related to greater next night SCT and SRT adherence. Alcohol consumption was related to poorer SRT and SH adherence the following night. Future studies should test the replicability of these findings. Adherence trials may want to test whether discouraging alcohol intake, enhancing treatment-related self-efficacy, and monitoring and providing feedback on sleep, early in treatment, affects adherence.     

Striving Towards Empowerment and Medication Adherence (STEP-AD): A Tailored Cognitive Behavioral Treatment Approach for Black Women Living With HIV

In the U.S. Black women with HIV face numerous psychosocial challenges, particularly trauma, racism, HIV-related discrimination, and gender role expectations, that are associated with negative HIV health outcomes and low medical treatment adherence. Yet many of these factors are unaddressed in traditional cognitive behavioral approaches. This study presents a case series of a tailored cognitive behavioral treatment approach for Black women living with HIV. Striving Towards EmPowerment and Medication Adherence (STEP-AD) is a 10-session treatment aimed at improving medication adherence for Black women with HIV by combining established cognitive behavioral strategies for trauma symptom reduction, strategies for coping with race- and HIV-related discrimination, gender empowerment, problem-solving techniques for medication adherence, and resilient coping. A case series study of five Black women with HIV was conducted to evaluate the preliminary acceptability and feasibility of the treatment and illustrate the approach. Findings support the potential promise of this treatment in helping to improve HIV medication adherence and decrease trauma symptoms. Areas for refinement in the treatment as well as structural barriers (e.g., housing) in the lives of the women that impacted their ability to fully benefit from the treatment are also noted.     

Critical Issues in Causation and Treatment of Autism: Why Fads Continue to Flourish

The increasing incidence of autism and the lack of specific answers regarding causation have given rise to unproven educational interventions and medical treatments. Parents of a newly diagnosed child can easily fall prey to interventions that promise cures. These interventions may be harmful and, thus, pose one of the critical issues in special education today. This article will discuss some of the suspect interventions that have been popularized through the media (i.e., celebrities, journalists, and professional organizations). The authors argue that using the scientific method is clearly the antidote for pseudoscience; the need for accurate research-based decision making is apparent.     

Does Motivational Interviewing (MI) Work With Nonaddicted Clients? A Controlled Study Measuring the Effects of a Brief Training in MI on Client Outcomes

This study investigated the relationships between motivational interviewing (MI) and client symptoms, attendance, and satisfaction. Seventy‐nine clients attending a university‐based counseling center were purposefully assigned to treatment or control conditions. Statistical analyses revealed client symptoms in both groups improved. However, clients assigned to treatment conditions attended more sessions and missed fewer sessions than clients in the control group. Implications for using MI and suggestions for additional research are explored within the study.
