A component of the United Nations Development Programme Human Development Index which measures longevity was negatively associated -.55 with suicide rates in 37 nations for men; the correlation with the suicide sex ratio was also negative (r = -.59). Women's access to social, political, and economic power in a subsample of 26 nations, summarized in the UNDP's Gender Empowerment Measure, was positively correlated with suicide rates (r = .36 for both women and men). UNDP measures of attainment in literacy and income showed no individual relationship with suicide rates. In a multiple regression model, life expectancy was negatively related, and the Gender-related Development index was positively related, to suicide rates. 相似文献

Should there be a three-strikes rule against pure discovery learning? The case for guided methods of instruction 总被引:17,自引:0,他引:17
Mayer RE 《The American psychologist》2004,59(1):14-19
The author's thesis is that there is sufficient research evidence to make any reasonable person skeptical about the benefits of discovery learning--practiced under the guise of cognitive constructivism or social constructivism--as a preferred instructional method. The author reviews research on discovery of problem-solving rules culminating in the 1960s, discovery of conservation strategies culminating in the 1970s, and discovery of LOGO programming strategies culminating in the 1980s. In each case, guided discovery was more effective than pure discovery in helping students learn and transfer. Overall, the constructivist view of learning may be best supported by methods of instruction that involve cognitive activity rather than behavioral activity, instructional guidance rather than pure discovery, and curricular focus rather than unstructured exploration. 相似文献

Contrasting fantasies about the future with reflections on reality that impedes fantasy realization creates a tight link between expectations of success and forming commitments to self-improvement goals. This effect applies to both fantasies about a positive future contrasted with impeding negative reality as well as fantasies about a negative future contrasted with impeding positive reality. In Study 1, with 63 student participants, contrasting positive fantasies about benefiting from a vocational training with negative reflections on reality impeding such benefits led to expectancy-dependent willingness to invest in the training, more so than indulging in the positive future and than dwelling on the negative reality. In Study 2, with 158 high school students from former East Berlin, contrasting negative, xenophobic fantasies about suffering from the influx of immigrants with positive reflections on reality impeding such suffering led to expectancy-dependent tolerance and willingness to integrate the immigrants. Findings are discussed in terms of how mental contrasting facilitates self-improvement and personal development by making people form expectancy-dependent goal commitments to approach positively-perceived as well as negatively-perceived futures. 相似文献

The psychometric properties of a new measure of dissociative behaviors, the Scale of Dissociative Activities (SODAS), were evaluated. Undergraduates (n = 533) completed the SODAS, 2 other established self-report measures of dissociative behaviors, and a measure of socially desirable responding. A randomly selected subset of participants (n = 100) also participated in an additional reliability and validity follow-up study. The SODAS was found to be internally consistent (a =.95) and temporally stable (r =.77) over an average 38-day interval. The validity of the SODAS was established by a moderately low negative correlation with social desirability, high correlations with other self-report measures of dissociation, and moderate to high correlations with samples of dissociative activities assessed in naturalistic environments with experience sampling methodology. Overall, the SODAS compared favorably to other existing self-report measures of dissociative behaviors. Directions for future research on the SODAS are discussed. 相似文献

The authors examined the relationship of a set of career variables, family cohesion, and demographic variables with the acculturation level of a sample of 176 Mexican American community college students. Multiple regression analyses using a blocked entry method revealed that only the demographic variables related significantly to acculturation. Based upon the zero order correlations, socioeconomic status would appear to account for most of the variance shared by acculturation and a linear combination of the demographic variables. 相似文献

By what process was the Jacobin identity transplanted into nineteenth-century Russian radical culture? According to the conventional account, the Jacobin label was coined by proponents like Zai?nevskij and Tka?ev. Lenin, in turn, is said to have derived his Jacobin identity from them, thus revealing the non-Marxian source of his political ideas. This article contests that interpretation through a study of the origin and spread of the Jacobin terminology in post-emancipation Russia. I show that the Jacobin identity in Russia was invented by anti-Jacobin populists and that there were scarcely any self-proclaimed Jacobins prior to Lenin. I also reconstruct the path by which Lenin came to identify with French Jacobinism. That path remained within the territory of Marxist theory from beginning to end. 相似文献

When the underlying distribution is discrete with a limited number of categories, methods for interval estimation of the intraclass correlation which assume normality are theoretically inadequate for use. On the basis of large sample theory, this paper develops an asymptotic closed-form interval estimate of the intraclass correlation for the case where there is a natural score associated with each category. This paper employs Monte Carlo simulation to demonstrate that when the underlying intraclass correlation is large, the traditional interval estimator which assumes normality can be misleading. We find that when the number of classes is 20, the interval estimator proposed here can generally perform reasonably well in a variety of situations. This paper further notes that the proposed interval estimator is invariant with respect to a linear transformation. When the data are on a nominal scale, an extension of the proposed method to account for this case, as well as a discussion on the relationship between the intraclass correlation and a kappa-type measure defined here and on the limitation of the corresponding kappa-type estimator are given.The authors wish to thank the Editor, the Associate Editor, and the three referees for many valuable comments and suggestions to improve the clarity of this paper.

Errors in child speech show that some children initially formulate tense-hopping and subject-auxiliary inversion as copying without deletion. Other errors suggest that some children may formulate other movement rules as deletion without copying. A claim about the nature of the language acquisition device is made on the basis of our analysis of these errors: the language acquisition device formulates hypotheses about transformations in terms of basic operations. The basic-operations hypothesis predicts that for any transformation which is composed of more than one basic operation, there exists a class of errors in child speech correctly analyzed as failure to apply one (or more) of the operations specified in the adult formulation of the rule. 相似文献
