What Makes Crohn's Disease Patients Difficult to Manage? The Role of Psychosocial Factors

Most GI clinicians face the problem of a small group Crohn's Disease (CD) patients who function poorly and consume inordinate amounts of service with poor outcome. This study examines the hypothesis that psychosocial factors differentiate the CD patients who function poorly from the typical CD patient. A prototypal sample of CD patients with problems functioning, more typical CD patients (not selected for having problems in functioning), and healthy controls each completed a battery of validated psychosocial measures of disease-specific quality of life, coping skills, social support and life stress, perceived medical symptoms and life history factors. Chart data on hospital admissions, ER, GI, Surgeon, and GP visits were also collected. The CD patients with problems functioning reported more symptoms (GI and non-GI) and had many more ER, GI, and GP visits than the typical group. Psychologically, those with problems functioning had poorer quality of life and were more likely to cope using emotional discharge and support seeking. They experienced significantly more stress and reported a more chaotic family history. No differences on an experimental method of information processing biases were found between the CD groups, however. These results indicated that patients with problems functioning, selected by GI staff because they were best-case examples of functional difficulties, shared little with a matched group of typical CD patients. These patients likely require psychological as well as medical intervention to best manage their illness.     

Timepieces: Components of Survey Question Response Latencies

Political scientists have increasingly found that the time respondents require to answer survey questions is a useful measure of the strength of political attitudes. However, questions remain about the collection, use, and interpretation of response time data— particularly latencies collected during telephone interviews, far removed from the controlled environment of a laboratory setting. This paper uses a theoretical model of question response to decompose survey response time data into three hypothesized elements—components of response time attributable to baseline individual differences, systematic question effects, and the accessibility of the attitudes being targeted. These findings have implications for the study of political attitudes and other mental constructs, as well as practical implications for public opinion survey researchers using response time data.

Reciprocal relationships between job resources, personal resources, and work engagement

This study examined longitudinal relationships between job resources, personal resources, and work engagement. On the basis of Conservation of Resources theory, we hypothesized that job resources, personal resources, and work engagement are reciprocal over time. The study was conducted among 163 employees, who were followed-up over a period of 18 months on average. Results of structural equation modeling analyses supported our hypotheses. Specifically, we found that T1 job and personal resources related positively to T2 work engagement. Additionally, T1 work engagement related positively to T2 job and personal resources. The model that fit best was the reciprocal model, which showed that not only resources and work engagement but also job and personal resources were mutually related. These findings support the assumption of Conservation of Resources theory that various types of resources and well-being evolve into a cycle that determines employees’ successful adaptation to their work environments.     

Psychological and demographic correlates of career patterns

Recent years have witnessed a growing diversity of career patterns, resulting from the relative decline of stable employment. In the present study of 1368 employed and self-employed German adults career pattern diversity was assessed using nine pictograms. The goal was to identify psychological and demographic correlates of these patterns and to answer the question of whether they differed for participants from the former (communist) East and the capitalist West. Findings indicated that upward-pointing career patterns still connected to extrinsic criteria such as income and job security. With regard to psychological correlates, upward patterns connected to lower work-related demands imposed by social change and a higher level of personal and social resources. Only in the West, upward patterns related to male gender and high education, reflecting more traditional access to upwardly mobile career opportunities.     

Resource-dependent effects during sex categorization

The limited capacity of face perception resources in the left cerebral hemisphere was examined using a sex categorization task. One study tested the hypothesis that sex categorization is impeded whenever feature extraction resources in the left hemisphere are simultaneously being utilized by another task. This hypothesis was tested by presenting prime faces for either 32 ms or 320 ms to either the left or right visual-field just before centrally presented target faces were categorized by sex. Results showed that sex categorization was slower after prime faces were presented for 32 ms in the right visual-field compared to the left visual-field. This difference was not found after the 320 ms prime length. The results are interpreted in the context of a neurocognitive model of social perception and suggest that efficient sex categorization depends, in part, on the availability of facial feature extraction resources in the left hemisphere.     

COGNITIVE DISABILITY IN A SOCIETY OF EQUALS

Abstract: This essay considers the range of possible policy options that are available if we wish to attempt to treat people with cognitive disabilities as equal members of society. It suggests that the goal of policy should be to allow each disabled person to establish a worthwhile place in the world and sets out four policy options: cash compensation, personal enhancement, status enhancement, and targeted resource enhancement. The essay argues for the social policy of targeted resource enhancement for individuals with cognitive disabilities, in the form of providing cash, with some limits on its use. Taking the example from the United Kingdom of "self-directed support," it argues that such policies can be cost-effective and advance the autonomy of people with cognitive disabilities, especially when compared with current policies of centrally provided services.     

Do the Weak Stand a Chance? Distribution of Resources in a Competitive Environment

When two agents of unequal strength compete, the stronger one is expected to always win the competition. This expectation is based on the assumption that evaluation of performance is complete, hence flawless. If, however, the agents are evaluated on the basis of only a small sample of their performance, the weaker agent still stands a chance of winning occasionally. A theoretical analysis indicates that, to increase the chance of this happening the weaker agent ought to give up on enough occasions so that he or she can match the stronger agent on the remaining ones. We model such a competition in a game, present its game-theoretic solution, and report an experiment, involving 144 individuals, in which we tested whether players (both weak and strong) are actually sensitive to their relative strengths and know how to allocate their resources accordingly. Our results indicate that they do.     

社会比较方向及目标可达性对行为水平的影响

采用“错觉合取效应”实验材料,以正确率和反应时为行为水平的指标,探讨在coaetion的情景下．不同的社会比较方向及比较目标的可达性对个体任务操作水平的影响。结果发现,成绩差异量越大．可达性越低：无论个体进行上行比较还是下行比较,当成绩差异量为20％时,其行为水平显著高于其他成绩差异量时的行为水平。上行比较时,不同的成绩差异量,任务操作的正确率由高到低依次为：20％、30％、10％、40％;下行比较时．不同的成绩差异量,任务操作的正确率由高到低依次为：20％、10％、30％、40％。对个体心理紧张度进行方差分析发现,当个体进行上行比较时,心理紧张度显著高于下行比较。     

Real World Justice

Despite a high and growing global average income, billions of human beings are still condemned to lifelong severe poverty with all its attendant evils of low life expectancy, social exclusion, ill health, illiteracy, dependency, and effective enslavement. We citizens of the rich countries are conditioned to think of this problem as an occasion for assistance. Thanks in part to the rationalizations dispensed by our economists, most of us do not realize how deeply we are implicated, through the new global economic order our states have imposed, in this ongoing catastrophe. My sketch of how we are so implicated follows the argument of my book, World Poverty and Human Rights, but takes the form of a response to the books critics.
