The LogicR4 is obtained by adding the axiom (A vB(AvB) to the modal relevant logicNR. We produce a model theory for this logic and show completeness. We also show that there is a natural embedding of a Kripke model forS4 in eachR4 model structure.We are indebted to several people for discussions relating to the topic of this paper, in particular, Kit Fine, John Slaney, J. M. Dunn, Jacques Riche, M. A. McRobbie, and Jill LeBlanc. We would also like to thank the Automated Reasoning Project for material assistance.

As reported in current research, many if not most freshmen and sophomores in colleges and universities who are declared as well as undeclared about their academic majors express uncertainty about their careers and lack the level of involvement in the career development process (especially self-assessment, career exploration, and career decision making) necessary to make educated career decisions. This research study, using both quantitative and qualitative research processes, identifies and examines differences and similarities in career uncertainty and in levels of involvement in the career development process between declared and undeclared college students. 相似文献

The present study investigated the validity of an inpatient pain behavior rating scale modified for outpatient use. A series of 43 consecutive outpatients referred for evaluation of chronic pain was examined using the Pain Behavior Scale (PBS) and other psychometric instruments. Analyses revealed significantly higher Pain Behavior Scale scores for low back and multiple pain-site groups. The results also indicated a high degree of internal consistency of the scale. A multiple regression analysis, predicting observed pain behavior from reported pain behavior, indicated that decreased activity accounted for 32% of the variance in the PBS score. A similar regression for pain experience found that the pain level and the sensory scale score on the McGill Pain Questionnaire accounted for 39% of the PBS variance. Psychological characteristics including disease conviction, self-control, depression, and anxiety explained 45% of the variability in the PBS score. Thus, the scale is related to pain intensity, interference with activities, and a variety of psychological characteristics. The scale provides a measure of observable pain behavior that is also relatively independent of these clinical data sources. The Pain Behavior Scale as modified for outpatient use provides a brief index of pain behavior with potential use in the comprehensive evaluation of the pain patient. 相似文献

Although group therapy is widely used in the treatment of children and adolescents, there has been little attention paid to establishing training standards and developing comprehensive programs for training psychiatry fellows in child and adolescent group psychotherapy. The authors conducted two surveys of child and adolescent training programs. After reviewing the literature, they present the data from their surveys, compare similarities and differences, and discuss trends. Finally, they propose a model for training in child and adolescent group therapy. 相似文献

Two experiments were simultaneously conducted in which two different groups of 40 rats each were exposed to one of two different stressors. In both experiments half the subjects were pretreated with shock, half with underwater exposure. For each pretreatment stressor, half the subjects were allowed to escape, the other half were not. The experiments differed in the test task used. Approximately 24 hr after pretreatment, one-half the subjects from each pretreatment group received 20 water-escape trials in an underwater maze, the other half received 20 shock-escape trials in a two-way shuttle box. The subjects in each of the inescapable pretreatment conditions were slower to escape in the subsequent shock-escape and water-escape tasks when compared with subjects in the corresponding escapable pretreatment condition. The “learned helplessness” effect appeared to be no smaller when aversive stimuli were changed between pretreatment and test than when they remained the same. 相似文献

An analysis of the meanings attached to 'careers education' in Britain and to 'career education' in the USA reveals a number of important differences, each of which identifies questionable assumptions in the careers education model emerging in Britain. Attention is also addressed to three major problems which have received inadequate attention in both countries: the socio-political aims of career(s) education, the extent to which it should be concerned with paid employment, and the relationship between the content of careers education curricula and the institutional structures within which these curricula are based. 相似文献
