The relationship between psychological contract breach and organizational commitment: Exchange imbalance as a moderator of the mediating role of violation

This study tested the mediating role of violation in the relationship between breach and both affective and continuance commitment and the extent to which this mediating role is moderated by exchange imbalance amongst a sample of 103 sales personnel. Results suggest that violation mediated the relationship between breach and commitment. Also, results suggest that perceived exchange imbalance moderates this mediating pathway: Low exchange imbalance increases the mediating role of violation in the case of affective commitment. On the other hand, exchange imbalance failed to moderate the mediating influence of violation in the case of continuance commitment. Results are discussed in view of the importance of a) including both measures of violation and breach in future studies and b) the role of social exchange in explaining psychological contract violation.

Treatment manuals: use in the treatment of bulimia nervosa

As psychology has moved toward emphasizing evidence-based practice, use of treatment manuals has extended from research trials into clinical practice. Minimal research has directly evaluated use of manuals in clinical practice. This survey of international eating disorder professionals examined use of manuals with 259 clinicians’ most recent client with bulimia nervosa. Although evidence-based manuals for bulimia nervosa exist, only 35.9% of clinicians reported using a manual. Clinicians were more likely to use a manual if they were younger; were treating an adult client; were clinical psychologists; were involved in research related to eating disorders; and endorsed a cognitive-behavioral orientation. Clinicians were less likely to use a manual if they provided eclectic psychotherapy that incorporated multiple psychotherapeutic approaches. We conclude that psychotherapy provided in clinical practice often does not align with the specific form validated in research trials, and “eclecticism” is at odds with efforts to disseminate manuals into clinical practice.     

Psychological wellbeing of Turkish university students with physical impairments: an evaluation within the stress-vulnerability paradigm

Generally, universities in developing countries offer little in the way of provisions and support (material, emotional, etc.) for disabled students. Therefore, disabled students experience considerable burdens and barriers in their educational life. This study investigated the psychological wellbeing of disabled Turkish university students by examining influences on stress-related growth and psychological distress. Disability is defined within the framework of a social model. According to this view, impairment refers to the functional limitation(s) that affect(s) a person's body, whereas disability refers to the loss or limitation of opportunities owing to social, physical or psychological obstacles. Seventy disabled university students with physical impairments were administered a questionnaire package, including a sociodemographic information sheet, Ways of Coping Questionnaire, Stress-Related Growth Scale, Multidimensional Scale of Social Support, Life Events Inventory, and Brief Symptom Inventory. Snowball sampling was used and voluntary participation was essential. The results showed that disability burden, daily hassles, and helplessness coping were significant predictors of psychological symptoms. For stress-related growth the only variable that appeared significant was problem-solving coping. The results pointed out that there may be different pathways to distress and growth. In order to decrease psychological distress and enhance growth in disabled university students, disability awareness programs, changes in the barriers in the academic and physical environments of the university campuses, and coping skills training to increase problem-focused coping and to combat helplessness may prove to be effective. Reducing daily hassles for the disabled students is likely to contribute to their wellbeing by decreasing their burdens. Also, a more disability-friendly environment is likely to be empowering for disabled university students.     

不同机械通气模式下吸痰对ARDS患者肺通气及顺应性的影响

为探讨不同机械通气模式下吸痰对ARDS患者肺通气及顺应性的影响。选择20例ARDS机械通气患者,随机分为A/C组与SIMV组;分别给予开放式吸痰,记录吸痰前后肺通气指标及呼吸系统顺应性指标的变化。结果吸痰后各时间点呼吸频率均显著增加(P0.01);潮气量、分钟通气量在0s显著降低,吸痰后15s、1min显著增加(P0.01);两通气模式比较SIMV组呼吸频率、分钟通气量增加显著(P0.01)。吸痰前后动静态顺应性、动态P-V曲线斜率差异不显著(P0.05),通气模式之间亦无统计学差异。提示开放式吸痰引起呼吸频率显著增加,潮气量及分钟通气量先是下降然后显著增加;SIMV模式呼吸频率、通气量增加较为显著。不同通气模式下吸痰对呼吸系统顺应性影响不显著。     

心理契约、工作满意度与组织承诺关系

深入研究心理契约、工作满意度与组织承诺关系,将对组织变革中的人力资源管理具有重要理论和实践价值。本文首先回顾心理契约、工作满意度和组织承诺的概念,其次对心理契约、工作满意度和组织承诺之间的关系做一简单总结,最后提出对人力资源管理实践的启示。     

人力资源实践对员工创新行为的影响：心理契约破裂的中介作用及上下级沟通的调节作用

本研究选取了影响员工创新行为的组织（人力资源管理实践）、个体（对心理契约破裂的感知）及领导因素（上下级沟通）,通过402名企业员工的问卷调查,采用有调节的中介研究设计,对人力资源实践影响员工创新行为的机制进行研究。结果发现：（1）人力资源管理实践水平与员工创新行为正相关;（2）心理契约破裂在人力资源管理实践与创新行为关系间起部分中介作用;（3）上下级沟通水平调节了心理契约破裂与创新行为的关系,也调节了心理契约破裂对人力资源实践与创新行为关系的中介作用。     

自我-他人决策差异：问题、研究与思考

目前关于自我-他人决策差异的研究在采用的任务、得到的发现及理论解释上均存在诸多矛盾或不一致的地方, 且缺乏对此种现象深层心理机制的探讨。虽然一些研究者试图用心理距离假设来解释相关结果, 但由于对心理距离的实验操纵过于简单, 难以形成解释力较强的理论模型。近年来我们的一系列研究发现：得失情境下自我-他人决策差异存在不对称性; 直接操纵心理距离比操纵决策者角色和社会距离对诱发自我-他人决策差异更有效; 决策者个体的自尊水平影响自我-他人决策差异。未来的研究需要进一步探讨自我-他人心理距离的本质、决策者角色转换引起的心理距离变化及自我-他人决策差异的脑机制等问题。     

The scientific use of ‘representation’ and ‘function’: avoiding explanatory vacuity

Nearly all of the ways philosophers currently attempt to define the terms ‘representation’ and ‘function’ undermine the scientific application of those terms by rendering the scientific explanations in which they occur vacuous. Since this is unacceptable, we must develop analyses of these terms that avoid this vacuity. Robert Cummins argues in this fashion in Representations, Targets, and Attitudes. He accuses ‘use theories’ of representational content of generating vacuous explanations, claims that nearly all current theories of representational content are use theories, and offers a non-use theory of representational content which avoids explanatory vacuity. One task I undertake in this article is to develop an alternative non-use theory which avoids an objection fatal to that theory. My second task is to adapt Cummins’ argument to criticize most current analyses of ‘function,’ which undermine scientific explanation in an analogous way. Though Cummins does not explicitly argue in this manner, his own analysis of ‘function,’ by avoiding any appeal to use, avoids the explanatory vacuity to which they succumb. Consequently, I endorse Cummins’ notion of function. However, although use theories fail as analyses of the terms ‘representation’ and ‘function,’ they can still make significant contributions to the sciences employing these terms. For, while philosophers seeking to define ‘representation’ and ‘function’ must avoid incorporating representational and functional uses into their definitions, scientists must still find a way to determine which representations and functions are being used. Suitably re-construed use theories of representation and function may in many cases assist them in this task.     

Optimism and pessimism as predictors of physical and psychological health among grandmothers raising their grandchildren

This study examines the role of personality in predicting psychological and physical health among grandmothers who are coping with a non-normative non-traumatic stressor, i.e. serving as primary caregivers for their grandchildren. Using the Life Orientation Test-Revised (LOT-R), a measure of personality disposition, we examine the contributions of both optimism and pessimism to health outcomes. ANOVAs and regression analyses of the LOT-R and self reports of health in 67 African American and Latino grandmothers revealed psychological (obsessive compulsive symptoms, depression, hostility) and physical (sleep disorder, hypertension) health outcomes are differentially predicted by optimism and pessimism among older and younger age-groups of grandmothers. Implications for grandmothers’ response to caregiving stress and for future studies of personality’s relation to health are discussed.
