解决“乙肝”问题亟须“四化”

乙型病毒性肝炎是一个严重的社会问题,而不是简单的医患之间的医疗和接受医疗的问题,它涉及到医疗机构、制药厂家以及社会、家庭、婚姻、就业等很多问题。要想从根本上解决乙型病毒性肝炎所带来的诸多问题需要全社会共同努力,形成一种“社会监督法制化、诊疗方案规范化、社会关爱人性化、具体施治个性化”的格局。     

老年人对退休生活的心理适应

本研究调查了退休老年人生活的心理适应情况,有70％的老年人能适应退休生活,30％则适应不良。调查研究表明:(1)适应退休生活与年龄、性别、文化、职业等有一定的关系;(2)老年人刚退休时的消极情绪反应与其对退休的心理准备呈负相关;(3)老年人能否适应退休生活,也受其过去生活满意感的影响;(4)找到对工作或消遣娱乐的老年人,多半能适应退休生活。     

经济体制改革中的组织发展研究

“组织发展”在中国还是一门新崛起的学科。在我国的改革的号召下,“组织发展”的实践却领先于理论的研究。农村的改革,给农民带来了自主权,取得了很大的成功,极大地推动了工业改革。开始,我们试行了弹性工时制,接着推行了目标管理,进而扩大到满负荷工作法和预见管理。同时我们又必须克服工人的短期行为,培养他们对企业长期利益的认同感,如今还在研究集中管理和分权管理,即参与管理的问题。我们深信,组织的发展最终还是取决于工人的素质,而训练和教育则是必然的手段。

Using a local Web browser as a multimedia platform for lecture and presentation support

As an alternative to commercial multimedia systems, lecturers may wish to consider using a Web browser for multimedia classroom presentations. Many Web browsers, including Netscape and Mosaic, can be configured for use in a “local mode” (i.e., without an active connection to the Internet). In this local mode, files, graphics, audio, and video can be accessed directly from the hard disk of the instructor’s computer. By using a laptop computer, an LCD panel, and an overhead projector, an instructor can present a classroom multimedia presentation that can also be published on the Web.     

The effects of interaction with the device described by procedural text on recall,true/false,and task performance

In two experiments, subjects interacted to different extents with relevant devices while reading two complex multistep procedural texts and were then tested with task performance time, true/false, and recall measures. While reading, subjects performed the task (read and do), saw the experimenter perform the task (read and see experimenter do), imagined doing the task (read and imagine), looked at the device while reading (read and see), or only read (read only). Van Dijk and Kintsch’s (1983) text representation theory led to the prediction that exposure to the task device (in the read-and-do, read-and-see, and read-and-see-experimenter-do conditions) would lead to the development of a stronger situation model and therefore faster task performance, whereas the read-only and read-andsee conditions would lead to a better textbase, and therefore better performance on the true/false and recall tasks. Paivio’s (1991) dual coding theory led to the opposite prediction for recall. The results supported the text representation theory with task performance and recall. The read-and-see condition produced consistently good performance on the true/false measure. Amount of text study time contributed to recall performance. These findings support the notion that information available while reading leads to differential development of representations in memory, which, in turn, causes differences in performance on various measures.     

Humor As a Stress Moderator in the Prediction of Blood Pressure Obtained during Five Stressful Tasks

In five consecutive stressful tasks we examined the role of humor as a potential stress moderator using systolic and diastolic blood pressure as an indication of cardiovascular reactivity. In all five tasks, the Coping Humor Scale interacted with sex in the prediction of blood pressure. The same pattern was found in response to each of the five tasks: Females who were higher in coping humor exhibited lower systolic blood pressure than females scoring lower on coping humor, while the reverse characterized males; males who scored high on the coping humor scale exhibited higher systolic blood pressure than males scoring low on that scale. Similar though less robust results were found when the Situational Humor Response Questionnaire was used as the measure of humor. In the Cold Pressor Task, which involves pain and endurance, interactions were found between humor, sex, and trials indicating a stress-moderator effect. The absence of interactions indicating stress moderation in most of the analyses with the other four stress tasks suggests that humor may play more of a role in moderating the impact of uncontrollable and passively experienced stressors. Tasks requiring more active, problem-solving behavior may be less amenable to the beneficial effects of humor. The findings do not clearly resolve the questions about the role of humor in effecting responses to stress. However, they do suggest that the subjects' sex may be an important consideration when evaluating the impact of humor as a stress moderator.     

The role of symmetrical and asymmetrical social conflict in cognitive change

We asked whether dyads consisting of nonconservers of liquid would be more likely than solo controls to change to a conservation answer when each child gave symmetrically conflicting answers from different perspectives ("more" versus "less" from different viewpoints). We also asked whether nonconservers are more likely than conservers to abandon their answers in conserver + nonconserver dyads. In order to stimulate the perspectival conflicts in the nonconserver + nonconserver dyads, the partners experienced artificial displays in which the two possible answers were afforded by different views of the apparatus. We found no evidence that social conflict of the kind engineered in the nonconserver + nonconserver dyads stimulates cognitive change. Our evidence that nonconservers tend to adopt the conservation answer of their partners was less strong than that collected in previous studies, but this may have been due to the fact that, contrary to previous studies, the children's social dominance relations were affecting the outcome. We concluded that the ineffectiveness of symmetrical social conflict is consistent with Piaget's conception of nonconservers as children insensitive to the perspective-relative nature of their judgments.
