The aim of this study was to test the direction of effect in the relationship between parents' sources of knowledge (parental monitoring and child disclosure) and adolescent alcohol use. The participants were 215 adolescents and their mothers, randomly selected from urban and rural areas in Cyprus. A 3‐month, two‐timepoint longitudinal design was used in which adolescents completed the alcohol use disorders identification test while mothers completed a parental knowledge questionnaire. The results of this study showed that parental monitoring did not predict subsequent adolescent alcohol use. However, child disclosure at Time 1 negatively predicted adolescent alcohol use at Time 2. Moreover, adolescents' alcohol dependence symptoms at Time 1 negatively predicted both sources of parental knowledge at Time 2.  相似文献

A computer virus is a program that replicates itself and spreads to computers with the goal of disrupting or destroying normal computer use. In academic computing, viruses represent a serious problem that costs millions of dollars in losses annually and hinders the free exchange of information so critical to education. Viruses operate in incubation, infection, and destroy phases. The nature, mechanisms, and preventive measures for personal-computer viruses are reviewed. Different procedures are recommended to protect research laboratories, instructional laboratories, and software lending libraries. Tradeoffs between providing adequate protection and not having the security become too burdensome are considered.  相似文献

Enhancements to the Micro Experimental Laboratory (MEL) and the ways in which they facilitate development of psychological experiments are discussed in this paper. New procedures are described for (1) presenting and manipulating pictorial graphics, (2) inputting response box, voice key, joystick, digitized speech, and mouse responses, (3) outputting lights, speech, and tone stimuli, (4) editing and analyzing digitized speech, and (5) implementing multitask processing. Methods for extending the language, developing test batteries, sequencing subjects, and managing and analyzing data are described.  相似文献

Topographic electroencephalographic alpha in recovered depressed elderly   总被引:1,自引:0,他引:1  
Late-middle-aged and elderly normal volunteers with past histories of Major Depression according to the Diagnostic and Statistical Manual of Mental Disorders (third edition-revised) criteria were compared with sex- and age-matched control subjects using topographic electroencephalographic (EEG) indices. Healthy, euthymic recovered depressed subjects showed greater alpha amplitudes than controls. Delta, theta, and beta amplitudes did not reliably distinguish the groups. Considered in the context of previous research indicating that actively depressed subjects exhibit elevated EEG alpha compared to controls, these findings raise questions concerning state and trait conceptualizations of depression and EEG alpha.  相似文献

Issues connected with sexuality such as heterosexual relationships, homosexuality, sexual identity, and seductiveness, create conflict and countertransference dilemmas for staff who work with psychiatric patients in a therapeutic community. When the therapeutic community is composed of adolescents, these issues are exacerbated since sexual identity and sexual development are major concerns. The staff reacts strongly to the issue of self-determination and violation/infringement on a basic human need. These philosophical differences have their roots in countertransference feelings. Staff sometimes find it difficult to confront adolescents on emotionally charged issues that have a sexual coloring. A system is proposed for articulating and working through these feelings. A unique solution is posited for solving this conflictual attitude (based on object relations theory), whereby the residential treatment center serves as the analog of the home in order to allow adolescents to develop a sense of self before they can move on to the halfway house where heterosexual behavior is allowed (as part of the therapeutic process). This facilitates the meeting of the "self" with the "other." This procedure is explored in light of Sullivan's concept of intimacy.  相似文献
