This experiment compared the extent to which students learned facts included in computer-based-training frames that required
an overt response to those that did not. Frames included two types of facts: Some facts had one word missing which had to
be supplied by the student (active facts). Other facts had no missing words and required no overt response (passive facts).
Each student completed four 14-fact modules in random order. Two of the modules contained frames with all active facts. Each
frame in the other two modules contained one active and six passive facts. Paper pretests and posttests showed that students
learned twice as many facts when all facts in the module were active than when only one in seven were active. The modules
that included passive facts required one-fifth the time to complete than those with only active facts. Students learned more
facts per minute of training in one of the two modules that included passive facts than in the two modules with only active
facts. 相似文献

This study investigated the personality and family-of-origin differences in male and female alcoholics. Results indicated that, regarding personality, men (both type 1 and type 2) were less troubled than were women. Implications for treatment based on these results are included. 相似文献

Molecular sequence data, made available in the last 15 years or so, have led to the classification of living cells into three phylogenetic domains: Bacteria, Archaea, and Eucarya. All the organisms that have been tested belonging to either domain were capable of mounting a stress response with essentially the same characteristics, regardless of the stressor. The protagonists in the cell's stress response are the stress genes and their protein products. Some of the latter are molecular chaperones. Under physiological conditions, these chaperones aid other cellular proteins to fold properly and achieve a native -functional- configuration, and to translocate from the place of synthesis to the cell's locale in which they will operate. In a stressed cell, the stress proteins that are chaperones protect other molecules from denaturation and help those partially damaged to regain a functional configuration. Thus, cell death is avoided and recovery is enhanced. The study of stress genes and proteins has progressed considerably in organisms belonging to the domains Bacteria and Eucarya. Less is known about the archaeal stress genes. Here, research with an organism from the Archaea is discussed, focusing on the stress genes of the hsp70 (dnaK) locus. Future perspectives for basic and applied research within the health sciences and biotechnology industries are presented. 相似文献

The axiomatic approaches of quantum mechanics and relativity theory are compared with approaches in which the theories are thought to describe readings of certain measurement operations. The usual axioms are shown to correspond with classes of ideal measurements. The necessity is discussed of generalizing the formalisms of both quantum mechanics and relativity theory so as to encompass more realistic nonideal measurements. It is argued that this generalization favours an empiricist interpretation of the mathematical formalisms over a realist one. 相似文献

In the postmodern information era with its increasing complexity and demands on my time, I find storytelling increasingly attractive. The right story told to the right person(s) at the right time in the right way can powerfully define and shape both individuals and the systems into which they organize themselves. As interventions go, I find stories to be relatively high impact, low-risk, parsimonious, and user-friendly. This paper contains some of my favorite teaching stories and describes why and how I use them as both a family therapist and teacher of family therapy. 相似文献

The aim of this study was to apply the narrative approach in analyzing family therapy meetings in cases of acute psychosis. The self-narrative is essential in acute psychosis since it is either collapsed or not coherent enough. The results indicate that it is important to create concrete practices that produce stories concerning the patient in relation to others. The self-narrative must be re-authored by the patient even though it is socially constructed. This is achieved by creating multiple perspectives of self-narratives in so-called therapy meetings with the patient, family members, and staff members representing different professionals. 相似文献

This paper discusses issues relating to therapeutic practice based upon the narrative metaphor. A case of someone suffering the effects of Dissociative Identity disorder is used to illustrate the difficulties that clients can experience with the “expert” knowledge conception of therapy. The value of the “respectful” and “non-expert” emphasis of Narrative Practice emerges even when the therapist believes that he or she lacks expertise in the client's apparent “condition.” Three themes emanating from the case form the basis for the discussion: the client's experience of being recruited into accepting the diagnostic label of Dissociative Identity Disorder; the effects of being forced to accept a contract to eliminate self-abusive behaviour; and the therapist's dealing with a gun in the therapy room. 相似文献

Supported by a review of relevant literature and a case study, the author argues that family therapy intervention enhances the likelihood of a female alcoholic's positive prognosis. With a basis in systems theory, family therapy views the family as a system and, hence, perceives the alcoholism as a symptom of that family. A profile of the female alcoholic, how her drinking affects her family, and the role that family therapy plays in the recovery process are examined. 相似文献

Over the past three decades, Arab society in Israel has been undergoing processes of transition. These processes are manifested by changes in the economy, education, the status of women, family structure, and by socio-cultural changes and transformations in patterns of coping with social problems. There is a serious lack of empirical research on the implications of this process for the value systems of Arab society and families in Israel and a dearth of relevant intervention-oriented literature. This article outlines the basic cultural values in the Arab society in Israel in an attempt to illuminate the relevance of these values for family structure and for direct interventions with Arab families in Israel. 相似文献
