The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his
D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based
on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes
the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation,
as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J.
Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

The association between personality and personal relationships is mostly studied within dyadic relationships. We examined these variables within the context of personal network types. We used Latent Class Analysis to identify groups of students with similar role relationships with three focal figures. We performed Latent Class Logistic Regression to explore the relationships of the latent classes with the Big Five personality factors. Personality was assessed with the Five Factor Personality Inventory. We found three personal network types: a primarily family oriented network, a primarily peer oriented network, and a mixed family/peer oriented network. We found significant associations between personality and personal network type. Extraverted students were more likely to have a primarily peer oriented network relative to a primarily family oriented network. Autonomous students were more likely to have a primarily family oriented network relative to a primarily peer oriented network. Autonomous students were also more likely to have a mixed family/peer oriented network relative to a primarily peer oriented network. Conscientious students were more likely to have a primarily family oriented network relative to a mixed family/peer oriented network. 相似文献

In a sample of 107 five-year-olds, cluster analysis was used to identify groups of children with similar profiles of competence and adaptation. A comprehensive set of child characteristics was included in the analysis, together covering the most important aspects of five-year-olds’ development and functioning. Three groups of children emerged, which were labeled Well-adapted/Competent, Underachieving/Internalizing, and Maladapted/Externalizing. Well-adapted/Competent children (59%) were competent and well-adjusted in all domains. The Maladapted/Externalizing children (22%) scored low in almost all domains of competence and functioning, and the Underachieving/Internalizing children (22%) showed a mixed profile of competence and adaptation. The differences in the quality of parent–child interaction that were observed between the groups provide clues as to how the different profiles of competence and adaptation are shaped and maintained in the interactions with parents. 相似文献

探讨2型糖尿病患者伴发脑卒中的发生率及相关危险因素,采用头CT扫描,化验血糖、胆固醇、甘油三酯、高密度脂蛋白、纤维蛋白原。对我院自2005年7月-2007年7月间收治的2型糖尿病合并脑卒中患者与非糖尿病发生脑卒中患者进行比较分析。200例患者中糖尿病88例,患病率44%,两组患者比较糖尿病并发脑卒中发生多灶性梗死(P〈0.01),血流变学分析(P〈0.01)其差异有统计学意义。糖尿病合并脑卒中的患者与多种危险因素有关,必须及早控制,防止脑卒中发生、发展,减少致残率。 相似文献

研究应用投资游戏任务及其变式,探讨了任务类型与性别属性对人际交往过程中信任给予和信任维持的影响。24名被试(平均年龄为20.41±1.99)通过轮组,完成了实验一和实验二的投资游戏任务。通过对投资比、返还比及其关系的比较和分析,结果发现:(1)在风险任务中,不同性别信任者的信任给予存在显著性差异,而且信任对象的性别属性对信任者的信任给予也存在显著性影响。(2)在无风险任务中,性别属性对信任对象的信任维持行为不存在显著影响,而信任者的信任给予对信任对象的行为具有显著的预测作用。这一结果表明,性别属性对人际信任的影响,与任务的风险性有关。 相似文献

本研究采用内隐联想测验,通过控制不同的反馈情境,采用前--后测实验设计进行实验.结果发现:(1)反馈情境是影响内隐自尊稳定性的一个重要因素.如果个体在特定情境下得到及时反馈,其内隐自尊会显著降低;而投有得到及时反馈韵个体,虽然内隐自尊并没有发生显著的变化,却表现出了一致的上升趋势.(2)与男性相比,女性的内隐自尊在一定情境下表现出了明显的不稳定性.(3)所有被试接受了不同的反馈后,在后测中的反应速度明显快于处理之前. 相似文献

本研究深入考察了我国现阶段小学儿童算术估算能力的发展状况。通过运用自编材料对1027名儿童的团体与个别测试,发现其估算能力的发展具有如下特点:(1)明显受到题目类型的影响,但在不同年龄阶段影响又不尽相同。(2)三年级可能是整数和小数估算能力发展的一个关键期,五年级是发展分数估算能力的较好时期。(3)不同估算策略的发展进程差别相当大,不同时期都有发展的侧重点。(4)小学儿童在估算时易发生多种错误,而且不同年级均有一些典型错误。另外研究还对儿童估算能力、策略与错误类型的发展进行了深入讨论。 相似文献

A sample of 122 female students attending a Pentecostal Bible College in England completed Form G (Anglicised) of the Myers‐Briggs Type Indicator (MBTI). The data demonstrated preferences for extraversion over introversion, for sensing over intuition, for feeling over thinking, and for judging over perceiving. The predominant type was ISFJ (16%), followed by ESFJ (12%). Comparison with the population norms demonstrated an over‐representation of intuitives among this sample of Bible College students. 相似文献
