The present paper takes a first step toward the integration of recent findings on brain dynamics and learning into established fields of psychophysiological science. Leading-edge studies of brain dynamics have shown that the brain manifests an inherent variability and that, when new stimuli (i.e., “problems”) are presented to the organism, brain chaos increases.  相似文献

This process evaluation study examined what variables moderate and mediate treatment effects on days in stable housing and client satisfaction for homeless mentally ill clients. In general, demographic characteristics did not moderate either outcome variable. Housing contacts, entitlement contacts, mental health contacts, and supportive services were significant mediators of the treatment effect on days in stable housing. Program contacts, mental health contacts, and supportive services were significant mediators of client satisfaction. The authors thank the National Institute of Mental Health for their financial support (MH43248, MH42357) for this project, Dorothy Gano for word processing and editorial assistance, and Gitry Heydebrand, Melissa Dannelet, Betty Tempelhoff, Ruth Smith, and Laeeq Ahmad for assisting in the interviews of clients. We are also appreciative of the cooperation given to us by the staffs of Malcolm Bliss Mental Health Center, St. Patrick's Center, the Community Advocacy and Support Alliance Program, and the St. Louisemergency shelters. Finally, we thank all of the participants in this study; we hope that their homelessness has now ended.

There is a growing awareness of how stress adversely affects organizational efficiency. The implementation of stress management programs to counteract this problem has been slow. This study examined such programs in companies who claimed that they were active and successful in stress management for their employees. The successful features of these organizational stress management programs are identified, discussed, and a model for organizations is presented.  相似文献

The efficacy of three different schedules of reinforcement for promoting and sustaining drug abstinence was compared in this study. Cigarette smoking was studied as an exemplar of stimulant drug self-administration. Sixty cigarette smokers were assigned to one of three groups (progressive rate of reinforcement, fixed rate of reinforcement, and yoked control). Participants in all three groups were asked to refrain from smoking for 1 week. Participants in the progressive and fixed groups achieved greater mean levels of abstinence than those in the control group. Participants in the progressive group were significantly less likely to resume smoking when they became abstinent than participants in the other groups.  相似文献

Therapists are increasingly considering chemical addiction from a family systems perspective. Effects of chemical dependency upon the family are discussed and intervention approaches aimed toward assisting the family as families redefine themselves and change their structure are considered. The integration of chemical dependency treatment and the family therapy is also discussed as it is practiced in an intensive outpatient program at a psychiatric hospital.  相似文献

In a follow-up to Juba (1997), the author suggests how a direct service practitioner can use Gustafson's (1992, 1995) concept of plot to help introduce narrative ideas within human service organizations and other systems. A general procedure is described and the concept is used to help practitioners develop specific strategies which may facilitate steps toward such introduction.  相似文献

In this study it was determined whether (a) classification as opposed to absence of classification has an effect on the quality of clinical hypotheses (b) the DSM-III-R and the CBCL have a different effect on the quality of clinical hypotheses, and (c) the potential difference between the DSM-III-R and the CBCL is moderated by the different number of syndromes identified by these systems. To investigate these questions, an experiment was conducted in which 86 clinicians generated hypotheses for six cases. The clinicians were divided into a DSM-III-R, a CBCL, and a control group. Of the six cases, two were classified by both classification systems as one syndrome, two were classified as one syndrome by the DSM-III-R but as two syndromes by the CBCL, and two were classified as two syndromes by the DSM-III-R but as one syndrome by the CBCL. The quality of the hypotheses was determined by means of four dependent variables selected from an overview of qualitative criteria: explanatory value, redundancy, possibility of operationalization, and specificity. No differences between the CBCL and the control groups were found. The DSM group performed better than the control group regarding explanatory value and redundancy. The DSM-III-R group also scored better than the CBCL group regarding explanatory value, particularly when the number of identified syndromes was two for the CBCL and one for the DSM-III-R.  相似文献

This paper situates Bogdanov in the context of social theory generally and socialist theory in particular. It outlines briefly the principal characteristics of his mature system, and assesses the strengths and weaknesses of his approach to the fundamental problems of social thought. The paper devotes particular attention to the problem of just how systems develop from less complex to more complex forms of organization, and evaluates Bogdanov’s solution to this problem against the background of populist, social democratic, and Leninist alternatives.  相似文献

本研究采用日本三隅二不二教授的PM领导行为理论 ,用中国修订版的PM量表对 2 64名初级军官的领导行为类型进行了评定 ,并与对中、日企业界的有关研究结果进行了比较 ,目的是研究初级军官所特有的领导行为特征以及与其相对应的情境因素。研究结果显示 :①在军事组织中 ,PM型是较理想的领导类型 ,其次为P型。这与中、日企业的结果有所不同。②方差分析结果表示 ,在与领导行为类型相关的八项情境因素中 ,初级军官在工作激励、连队满意度、团队精神和会议成效等因子上高于中、日企业界 ;但在心理卫生、对待遇满意度、信息沟通和绩效规范等因子上均低于中国企业界。③ χ2 分析结果显示 ,三种组织与四种PM行为类型之间在六项情境因素上的差异显著 ,提示三种组织在领导行为和情境因素上各有其特点 ;另外 ,与军事指挥官领导行为类型关系最为密切的是工作激励因素和团队精神 ,这是军事集团突出的特征之一。④中、日企业界在会议成效和信息沟通两因素上的差异较大 ,反映了两国在企业管理方面不同的特点。  相似文献

New York State's initial attempt at individualizing services occurred within the context of an experiment. We randomly assigned children 5–12 years old who were referred for out-of-home placement in treatment foster care to either treatment foster care, Family-Based Treatment (n=15), or to Family-Centered Intensive Case Management (FCICM) (n=27). FCICM used teams of case managers and parent advocates to provide in-home services. Flexible service dollars, respite care, and behavior management skills training were available to assist teams in individualizing care. Preliminary outcomes indicate that children in FCICM are doing as well or better than children assigned to FBT in their functioning and symptom reduction. Parents of children in FCICM have made gains, although not at a statistically significant level, in behavior management skills and family strengths that allow them to provide care for their children at home.  相似文献
