In continuation of our study of HST, Hrbaek set theory (a nonstandard set theory which includes, in particular, the ZFC Replacement and Separation schemata in the st--language, and Saturation for well-orderable families of internal sets), we consider the problem of existence of elementary extensions of inner "external" subclasses of the HST universe.We show that, given a standard cardinal , any set R * generates an "internal" class S(R) of all sets standard relatively to elements of R, and an "external" class L[S(R)] of all sets constructible (in a sense close to the Gödel constructibility) from sets in S(R). We prove that under some mild saturation-like requirements for R the class L[S(R)] models a certain -version of HST including the principle of +-saturation; moreover, in this case L[S(R)] is an elementary extension of L[S(R)] in the st--language whenever sets R R satisfy the requirements. 相似文献

Social support systems can have either a beneficial or adverse effect when a family faces stress. Hence, support perceived by family members is an important construct. We studied the psychometric properties of the Family Support Scale (FSS) with a sample of 244 low-income families of children in a Head Start program, and we conducted an exploratory factor analysis with the scale. We obtained a 5-factor solution for the FSS when assessing the family support of low-income families. The internal consistency and test-retest reliability were moderately high for the 5 proposed subscales. The factor structure obtained may prove more valid for Head Start families than structures from previous studies, although there is still a need for further psychometric study of the FSS. 相似文献

Medical semiotics in the 18th century was more than a premodern form of diagnosis. Its structure allowed for the combination of empirically proven rules of instruction with the theoretical knowledge of the new sciences, employing the relation between the sign and the signified. 相似文献

The present study applied Karolinska Scales of Personality (KSP) to study (i) if patients with benzodiazepine dependence have a characteristic personality profile, (ii) if the personality characteristics in patients with benzodiazepine dependence differ from those of polydrug users and normal controls, (iii) if differences in treatment outcome existed between the groups, and (iv) if the possible difference in treatment outcome was associated with any particular personality characteristic shown by the patients. The personality characteristics of primary benzodiazepine dependent patients (BDZ) and a group of polydrug users (MIX) were studied initially (during the first week in project as an inpatient) and approximately one year after drug discontinuation, and a comparison was made with healthy controls on both test occasions. The results showed that the personality of both groups of patients differed significantly from the Controls in the following characteristics: Detachment, Socialization, Somatic Anxiety, Muscular Tension, Psychic Anxiety, and Psychasthenia. Significant differences existed between the polydrug and benzodiazepine users in Somatic and Psychic Anxiety as well as in Socialization. The MIX group differed significantly from the BDZ group and from the Controls in Suspicion. Results of treatment outcome indicated that the benzodiazepine dependent patients were significantly more successful in quitting their drug use compared to polydrug users. Further, the results demonstrated that patients scoring high in the investigated personality characteristics are those who fail the treatment goal of quitting their drug use, especially the patients with a high level of anxiety and detachment. 相似文献

在内隐学习条件下任务难度对于判断准确率的影响 总被引:3,自引:0,他引:3
本研究利用自行设计的复杂规则产生出不同难度的任务系统,进而通过实验阐明了内隐学习的三个特征;(一)在任务难度极大的情况下,内隐学习并不发挥作用;(二)在任务难度降低到一定程度的时间,内隐学习开始发挥作用,这仿佛是一个“阈限”;(三)随着任务难度逐渐降低,内隐学习的效率也随着提高,但是最科停止在一个较高的水平而再继续上升,可以间接推断,内隐学习获得了样例的具体信息。 相似文献

The current research examined differences between women engineers who persisted in an engineering career versus those who left engineering using a combination of two prominent theories of career change: social cognitive career theory (SCCT, Lent, Brown & Hackett, 1994; 2002) and integrated model of career change (Rhodes & Doering, 1983). The two groups of women did not differ in three domains of self-confidence or outcome expectations (engineering tasks, navigating organizational climate, or multiple roles), in vocational interests, or in workplace barriers. Women who continue in engineering do differ from those who leave in their experience of workplace supports and their levels of occupational commitment. Engineering turnover intentions and occupational commitment emerged as the two key variables that explained 33.4% of the variance in persistence in engineering careers. We discuss the implications of the results in terms of theoretical development and practical implications for organizations. 相似文献

The relations between interests, personality and career adaptability were explored in two separate studies. In the first study, the RIASEC measure Occupational Preference Scale was applied along with personality inventories HEXACO-PI-(R)-100 and IPIP-50 on a sample of 602 university students and young adults. In the second study, PGI-Short, HEXACO-60 and Career Adapt-Abilities Scale were applied on a sample of 981 high-school graduates. Results from both studies were discussed together, and general conclusions about overlapping of interests, personality and career adaptability domains were drawn on the basis of correlational analyses and property vector fitting. Both studies have shown weak to moderate relations between interests and personality. In the HEXACO framework, it was found that Openness to Experience was positively related to creative interests, Emotionality was positively related to social interests and negatively related to technical interests, Extraversion was positively related to social and managing interests, and Honesty–Humility was negatively related to interests for business and finance. In the Big Five framework, Agreeableness was related to Social and Artistic interests, and Intellect to Artistic interests. The HEXACO personality domains showed predictive advantage for explaining interests in comparison to Big Five dimensions. The relation between career adaptability and interests was weak, and almost negligible when personality was included in hierarchical regression analysis. Career adaptability was weakly related to highly prestigious interests. Adaptability facets Concern, Control and Confidence were oriented toward data pole of interest space. The general factor of interests was weakly correlated with Openness Extraversion, Career Adaptability, and adaptability facets Confidence and Curiosity. Observed findings are as expected and in line with previous research. 相似文献

Based on organizational socialization literature (e.g., Bauer, Bodner, Erdogan, Truxillo, & Tucker, 2007; Kammeyer-Mueller & Wanberg, 2003; Saks, Uggerslev, & Fassina, 2007) and Conservation of Resources theory (COR theory; Hobfoll, 1989, 2001), this article aims to develop a conceptualization and a measurement of cognitive adjustment at work (CAW), as an indicator of psychological health in the workplace. Two studies, including three independent samples (NA = 296, NB = 350, NC = 139), were conducted to test an operational proposal of CAW. In Study 1, exploratory and confirmatory factor analyses, as well as reliability and temporal invariance analyses, were performed to test the structure of both the construct and the instrument. In Study 2, nomological network analysis was conducted. Results suggest strong empirical support for the structure and validity of CAW, defined as a second-order factor, which includes task adjustment, work group adjustment and organizational adjustment. 相似文献
