A survey in an unincorporated urban area compared the major community problems of concern to two groups: (a) a randomly selected sample of listed telephone subscribers, and (b) community leaders identified through nominations and reputational methods. In addition to asking about the major problems of the community, the randomly selected telephone subscribers were also asked to indicate for each problem (a) the persons or organizations to whom they looked for information and advice, (b) whom they considered qualified to speak for them, and (c) whom they expected to act in their behalf in the solution of these problems. The results of these surveys showed a large divergence of concerns expressed by the random samples and the reputed community leaders, as well as a striking number of respondents who felt themselves to be without spokesmen.  相似文献

An apparatus suitable for conducting simultaneous or delayed matching-to-sample experiments with as many as eight comparison stimuli is described. Data are presented which indicate that pigeons are capable of performing such a task. It is concluded that the simultaneous matching-to-sample procedure with more than two comparison stimuli is an efficient means of obtaining information about discrimination capacity and that this procedure may be suitable for studying visual perception in infrahuman Ss.  相似文献

This paper examined (1) the association between parents who are convicted of a substance-related offense and their children’s probability of being arrested as a young adult and (2) whether or not parental participation in an adult drug treatment court program mitigated this risk. The analysis relied on state administrative data from North Carolina courts (2005–2013) and from birth records (1988–2003). The dependent variable was the probability that a child was arrested as a young adult (16–21). Logistic regression was used to compare groups and models accounted for the clustering of multiple children with the same mother. Findings revealed that children whose parents were convicted on either a substance-related charge on a non-substance-related charge had twice the odds of being arrested as young adult, relative to children whose parents had not been observed having a conviction. While a quarter of children whose parents participated in a drug treatment court program were arrested as young adults, parental completion this program did not reduce this risk. In conclusion, children whose parents were convicted had an increased risk of being arrested as young adults, irrespective of whether or not the conviction was on a substance-related charge. However, drug treatment courts did not reduce this risk. Reducing intergenerational links in the probability of arrest remains a societal challenge.  相似文献

Training, coaching, and consulting with people in leadership roles can be a primary consulting function for clinicians. In this paper, the authors describe their model of leadership, and what they believe to be the central personality or character components of leadership necessary for producing extraordinary results. Throughout they will show where and how REBT skills can make a significant contribution.  相似文献

In this essay, the core concepts of psychoanalysis are set forth as the context for the application of classical psychoanalytic theory to the practice of couple therapy. Infantile sexuality and aggression are shown to have a powerful role in the interpersonal lives of family members. The repetition compulsion structures marital interaction and intergenerational dynamics. The intrapsychic emphasis of classical ego-psychology is viewed in the interpersonal arena, and the author suggests adding to the Oedipus and Narcissus myths a myth that resonates with this shift in emphasis. In introducing the “Pygmalion–Galatea process,” the author captures the universal attempt to change the psychic dynamics of the other or others. This ultimately mutual process begins with the infant's mirroring of its caretakers—which includes language acquisition. Much of human interaction is fueled by subsequent attempts to create others in our own images of them and by their reactive compliance or resistance to that dynamic. Three case illustrations are presented to show how these phenomena manifest themselves in marital interaction and in dreams.  相似文献

Assertions that studying is done best at a desk rather than on a bed are largely untested. In the present study the GPA of students working at their desks was compared with that of students studying on their beds. There was no difference in the GPA's of the two groups. The assumption that there is a single type of study environment optimal for all students appears unwarranted. Since a sizable number of college students use their beds and even the floor for studying, the use of softer and more comfortable furniture in libraries and study halls deserves consideration.  相似文献

In investigations of the perception of space, the consideration of ocular counterrolling-the movement of the eye around its visual axis in response to body movement-is crucially important. The angle of this movement must be known in order for one to determine the precise retinal coordinates of a distal object. Following transformation, this stimulus serves as a reliable cue for visual direction. The otolith organs provide information about body tilt and are responsible for ocular counterrolling. A novel, noninvasive method to measure ocular counterrolling, based on the cross-correlation of digitized video pictures of the eyes, is presented. The resolution attained was ≤ 0.1°. The computer analysis is fully automatic and fast, and it can be performed while subjects work on perceptual tasks. No direct access to the eyeballs is required. Data from 4 subjects showing the counterrolling profile in various body positions are presented.  相似文献
