In the late summer and fall of 1983 articles appeared in such publications as the New York Times, Fortune Magazine , and Science News telling of attempts to set up an agency for the selling of kidneys from living donors. The shortage of organs, especially of kidneys where the transplantation success has increased quite markedly over the past decade, has become something of a crisis. A situation of increased need and inadequate supply is also becoming a problem for such substances as human bone marrow, for use in the treatment of immune and blood diseases, and large quantities of human plasma for use by hemophiliacs. Obtaining a kidney for a patient in renal failure was difficult in the past because adequate matching is likely only between very close relatives. Now with new immunosuppressant drugs such as cyclosporine, close matches have become less important. Cadaver organs or marrow from unrelated living donors can be used with far greater success. The supply problem is still immense and the literature is filled with suggestions for appropriate and efficient means of organ acquisition. One of the latest suggestions involves a system of salvaging based on implied consent of deceased donors. The organs would be taken without asking directly for permission from family. The relatives would have the right to object to the organ removal, but unless they did so, the organ would be taken when needed.  相似文献

The present study was designed to investigate student behaviour in a river-crossing problem in light of prior experience, intelligence, personality, mode of presentation and age. Ninety-six students at Year 6 and 61 students at Year 8 from schools in Australia were administered the Eysenck Junior EPQ and IVE scales, together with six cognitive tasks used to index the Luria successive and simultaneous processing and planning functional units. Each student was given a river-crossing problem presented in one of two modes and at one of two levels of difficulty. Success on the river-crossing problem was found to be independent of age, mode of presentation or prior experience on the task. There was a significant effect due to problem awareness, intelligence and empathy and a mode by success interaction. An attempt was made to group students into problem-solver ‘types’. The results were discussed in terms of the link between cognitive and affective variables and intervention programmes.  相似文献

AN OVERVIEW OF THE ARMY SELECTION AND CLASSIFICATION PROJECT (PROJECT A)   总被引:7,自引:0,他引:7  
This paper serves as an introduction and background for the remaining papers in this issue, which describe in somewhat more detail the major pieces in the Army's Selection and Classification Project (Project A). The principal objectives, the methods being used, and the basic research design of Project A are outlined. Project A was a 7-year effort conducted by the Army Research Institute and a consortium of three research firms. The overall objective was to generate the instrumentation and validity information data base that are necessary for modeling and developing an organization-wide selection and classification system. Both the scientific and practical implications of the project are noted.  相似文献

This paper describes the development and main results over the last 30 years from the treatment-research project with developmentally disabled (autistic) children in the Psychology Department at the University of California, Los Angeles (UCLA). Three important dimensions in treatment research are addressed. The first pertains to the role of serendipity or accidental discoveries, the second to the importance of pursuing inductive rather than theory-driven research, and the third to the importance of adding in a cumulative and step-wise manner to improve treatment adequacy. Data from various areas of treatment research have been used to illustrate new directions for the project. These illustrations center on early and successful attempts to isolate experimentally the environmental variables that control self-injury, failure to observe response and stimulus generalization with subsequent loss of treatment gains, and the main results of intensive and early behavioral intervention in the child's natural environment. Effective treatment for severe behavioral disorders is seen to require early intervention carried out during all or most of the child's waking hours, addressing all significant behaviors in all of the child's environments, by all significant persons, for many years.  相似文献

Stanley Hauerwas has been seen as a staunch opponent of liberal Protestantism. However his upbringing, education, and theological points of emphasis suggest that his work is best understood as in internal critique of liberal Protestantism, one that follows in a tradition of twentieth‐century theological renewals.  相似文献

A predictor battery of cognitive ability, perceptual-psychomotor ability, temperament/personality, interest, and job outcome preference measures was administered to enlisted soldiers in nine Army jobs. These measures were summarized in terms of 24 composite scores. The relationships between the predictor composite scores and five components of job performance were analyzed. Scores from the cognitive and perceptual-psychomotor ability tests provided the best prediction of job-specific and general task proficiency, while the temperament/personality composites were the best predictors of giving extra effort, supporting peers, and exhibiting personal discipline. Composite scores derived from the interest inventory were correlated more highly with task proficiency than with demonstrating effort and peer support. In particular, vocational interests were among the best predictors of task proficiency in combat jobs. The results suggest that the Army can improve the prediction of job performance by adding non-cognitive predictors to its present battery of predictor tests.  相似文献

Few behaviors have been found that consistently differentiate deceivers from truth-tellers. Consequently, recent research has focused upon identifying the factors that impact upon the display of behavioral correlates of deception. Following previous work in this area, four factors held to be important in this regard are reviewed: arousal, emotion, cognitive difficulty, and control. An integrative model that explicates the interrelations of these components is then developed. Finally, a study examining the effects of preparation and control on leakage during deception is presented. Planning of deception was found to relate to response latency and duration of eye contact. In addition, subjects appear to use inhibitory control processes to suppress the display of behavioral cues of deception.  相似文献

The present study investigated simultaneous-successive syntheses and planning as cognitive processing constructs in 66 grade 4 and 63 grade 6 Chinese children. Principal factor and promax analyses provided evidence of the realities of these independent factors. Simultaneous and successive components contributed to composite reading with varying degrees of variance for each grade. The Luria paradigm provides a useful framework for research into patterns of readers.  相似文献

对应对效能的测量研究抽取了1806名高校大学生样本,另对某戒毒机构中30人的吸毒特殊人群进行了比较研究。结构方程建模的验证性研究证实了应对效能的存在及其重要作用:应对效能区别于一般自我效能,在对躯体症状、抑郁和焦虑的作用中,以及对严重突发性事件如对可能出现的SARS的应激反应的作用中,发挥更重要的作用;应对效能发挥作用的机制表明它是一个独立的更为稳定的变量。根据应对效能的理论假设编制的量表有良好的信度与效度。其克伦巴赫α系数为0.86,分半信度0.79,相隔两个月63个被试的重测信度为0.71。探索性因素分析和验证性因素分析揭示应对效能主要由三个因素构成,即自信程度、认知水平、胜任力的知觉。问卷的聚合效度与区分效度也比较满意。30个人的吸毒者与一般正常人的比较提供了实证效度的证据,应对效能能够有效区分吸毒人群与一般正常人群。以全国大学生的样本,建立了应对效能量表的常模。  相似文献

Abstract. Scientific understandings suggest very strongly that humans are related to the rest of nature in ways that are expressed both by metaphors of genetic kinship and by ecological interrelatedness. The image of genetic kinship is the more intense image, and also the most likely to cause discomfort for Western traditions. Both secular critical reason and Western religious traditions favor images that portray the relation of humans to nature in terms of separation, domination, and stewardship. At best they are ambivalent toward portrayals of a more intense relatedness. In order to best serve our self-understandings, we must recognize (1) our intrinsic kinship with the rest of nature; (2) that our purpose as humans is to serve nature; (3) that we are preparers for nature's future; (4) that our highest calling as humans is to discern the dimensions of ultimacy in nature and to conceptualize them. In this, we follow God's own pattern of investing in nature as the greatest project.  相似文献

The data base for the Army Selection and Classification Project (Project A) contains two major samples referred to as the concurrent validation sample and the longitudinal validation sample. The former was drawn from a cohort that joined the Army in 1983/84, and the latter from a cohort that entered in 1986/87. This paper describes the data base resulting from the concurrent sample. The sampling procedure, the distribution of sample sizes over jobs, the total array of variables, and the data collection procedures are described. Also discussed are the extensive data editing procedures that were used to deal with missing data.  相似文献

The relative effectiveness of incentive plans administered on continuous and VR-4 schedules of reinforcement was investigated with unionized employees using a within subjects design. Mountain beaver trappers working side by side were randomly assigned to one of two groups. In group A the trappers received $1.00 for every rat they trapped. At the end of four weeks, they were switched to a VR-4 schedule in which they received $4.00 contingent upon trapping a rat and correctly guessing the color of one of four marbles prior to drawing it from a bag held by the supervisor. In group B the order of the schedules was reversed. The results were analyzed in terms of cost-related, behavioral, and reaction criteria. The study increased employee productivity and decreased costs for the company. Inexperienced workers had higher productivity on the continuous reinforcement than on the VR-4 schedule; experienced workers had higher productivity on the VR-4 schedule than on the continuous schedule. Both the experienced and the inexperienced employees preferred the VR-4 schedule over the continuous schedule.  相似文献

Career planning programs require participant effort to influence career progress. This study investigated the relationship of beliefs in internal vs. external locus of control of behavior (I/E) and self-reported activity four months after a one-day career planning workshop. Internally oriented secretaries took more actions to explore potential career goals and to identify means of attaining these goals. In addition, respondents to the follow-up questionnaire were more internally oriented than non-respondents. Implications for administration of career planning programs are listed.  相似文献

This article describes the group process in a feminist research project on resiliency in adult women survivors of childhood sexual abuse. Memos written by members of the research team that were content analyzed independently provided the major source of data. Researchers' subjectivity, members' expectations for intimacy, and the role of power were examined. We describe how group members learned that taking the researcher's subjectivity into account affected our understanding of participant stories. The longing for intimacy created frustrations that needed to be acknowledged and processed by the group. Further tensions revolved around the feminist ideal of egalitarian relationships, which at times conflicted with the need for efficient decision making. We conclude with suggestions to aid feminist researchers in negotiating process issues.  相似文献
