The present paper proposes a new psychophysiological approach to the genesis of positive and negative schizophrenic symptoms. According to this approach, the initial factor in schizophrenic disorders is a functional insufficiency of the right hemisphere which can be determined by early emotional experience in combination with subtle brain damage. This functional insufficiency causes (a) the inability to grasp and select information before its realization; and (b) the inability to produce a polysemantic context which is crucial for creativity, psychological defense, and the restoration of search activity, all of which determine psychophysiological adaptation to the environment. Right hemisphere insufficiency causes left hemisphere hyperactivity as an ineffective attempt to compensate for this functional deficiency. As a result, normal search activity is replaced by artificial search activity which is represented by “positive” symptoms, and which uses the predisposition of the left hemisphere's catecholamine system for its increased activity. The suggestion is made that cognitive impairment in schizophrenia (the inability to use appropriate previous information in relation to current perceptual input) is related to the competition between information processing which requires left hemisphere activity, and the formation of positive symptoms, also based on left hemisphere activity.  相似文献

Based on the fuzzy characteristic of the pulse state and syndromes differentiation thinking mode of TCM, an information fusing recognition method of pulse states based on SFNN (Stochastic Fuzzy Neural Network) is presented in this paper. With the learning ability in parameters and structure, SFNN fuses the measurement information of three pulse-state sensors distributed in Cun, Guan, and Chi location of body for the pulse state recognition. The experimental results show that the percentage of correct recognition with new method is higher than that by single-data recognition one, with fewer off-line train numbers.  相似文献

后现代心理学概观   总被引:5,自引:0,他引:5  
后现代心理学家反对以往的心理学理论和流派把心理或行为看作是一个独立于研究者的“实体”。后现代心理学的典型特征是反对基础主义和本质主义。它认为心理现象并不是一种“精神实在” ,而是一种文化的社会建构。后现代心理学的理论基础是社会建构论 ,多元文化论、后现代女性心理学都是后现代心理学的重要形式。  相似文献

人力资源战略在医院管理中的运用及价值探讨   总被引:5,自引:1,他引:4  
余彬  徐伟伟 《中国医院》2004,8(1):39-41
人力资源是医院最重要的资源,随着国内医疗市场的逐步开放和"三医"联动医药卫生体制改革的实施,医院之间的竞争愈加表现为人才的竞争,作为医院的高层管理者在战略决策管理中如何通过合理的人才战略和管理机制,吸引、培养、留下更多的人才并最大程度地调动他们的积极性和创造性显得十分重要.本文重点阐述了医院实施人力资源战略管理的方法,认为个人目标与组织目标保持高度一致,设计合理、灵活、富有激励的绩效考核办法是医院人力资源战略管理的关键所在.  相似文献

This study uses the Taiwan Healthcare Indicator Series (THIS) system as an example to examine which determinants would improve performance by sharing indicators from a management perspective. This study population included all 227 hospitals participating in the THIS system in 2006. A structured questionnaire was sent to the director who was responsible for the THIS system via electronic mail. A total of 111 responses were returned by February 10, 2006. Questions included current implementation and impacts of the system. Hierarchical regression models were performed to identify which variables were significantly associated with performance improvement, adjusted for hospital characteristics. Four variables significantly associated with implementing the THIS system to improve performance were ‘senior management support,’ ‘benchmarking,’ ‘making departments improve the underperforming indicators and report the improvement results in performance management meetings,’ and ‘integration with the National Health Insurance payment regulations’. This study contributes substantially to the evidence base about what works to improve performance by information sharing. Although information sharing is the basis of efforts to improve performance, senior management support and how to effectively apply the information are the most important determinants of performance enhancement.  相似文献

This paper, updating the findings of an earlier study, provides additional evidence that sheet metal workers in the construction trades are at increased risk for asbestos-related disease. A proportional analysis of cause of death among 331 New York sheet metal workers found a significantly elevated PMR for lung cancer (PMR = 186). In addition, there were six deaths attributable to mesothelioma (three classified as lung cancer deaths) and three death certificates mentioned asbestosis or pulmonary fibrosis, although none of these three deaths were attributed to these diseases.  相似文献

Exposure to mineral dust was studied among construction workers (N = 437) with the aid of a questionnaire and a chest X-ray examination of the lungs. The results of the questionnaire showed that 81% of the construction workers had been exposed to asbestos. Exposure had occurred in all of the occupational groups studied. Pleural plaques and/or lung fibrosis (ILO greater than or equal to 1/1) were found in 26% of the examined workers; the prevalence varied from 18 to 40% among the various occupational groups. Comparison with a representative sample of the Finnish male population from another investigation indicates that the frequency of lung fibrosis (ILO greater than or equal to 1/1) is at least two times higher among the examined construction workers than among the general population. It seems likely that exposure to asbestos dust can be considered an etiological factor for an appreciable number of the X-ray findings.  相似文献
