AbstractWe investigated the process through which children understand the conventional use of numbers in interaction with an adult. We analysed previous semiotic systems that support, transform and adjust to this new semiotic system — the numerical — and we investigated the communicative-educative basis that makes it possible. We conducted an exploratory and longitudinal study with one boy and one girl at 24, 27, 30, 33 and 36 months of age in a triadic interaction (adult-child-object) with their mothers at home. We adopt the pragmatic-semiotic perspective of the object, which considers that triadic interactions are the unit of analysis of early development. Our results show a great variety of semiotic mediators used by children and adults and both children’s progressive comprehension of the meaning and use of the die as a numerical object. 相似文献

Several theoretical models and testing procedures are presented with the aim of identifying the most relevant items and domains to include in a model for evaluating adolescents’ subjective well-being, above and beyond those usually included in adults’ scales. Data were collected in three countries based on a list of 30 items regarding adolescents’ satisfaction with different domains or facets of life. Responses to these 30 items (including Personal Well-Being Index and Brief Multidimensional Students’ Life Satisfaction Scale items) have been analysed by means of Confirmatory Factor Analysis using different Structural Equation Models (SEM) on a pooled sample comprising 5,316 twelve to sixteen-year-olds from Spain, Brazil and Chile. Several models have shown good enough fit statistics. A model using 14 items shows excellent fit statistics and is conceptually coherent. However, the inclusion or non-inclusion of items related to satisfaction with religion or spirituality results in both advantages and disadvantages when comparing the alternative models analysed. The relevance of including these items may therefore depend on the socio-cultural context where data are collected and their inclusion makes cross-country comparison more statistically challenging. The 14-item model has also been tested using multigroup SEM in order to check comparability of data among the three countries. All things considered, multigroup models have shown good fit with constrained loadings, but not with constrained loadings and intercepts, suggesting we can compare correlations and regressions among countries, but not means. Additional multigroup SEM with the five age groups available from the pooled sample have demonstrated that responses—and means—are comparable across different age groups during early adolescence. 相似文献

Reemployment chances for unemployed aged fifty and over are low compared to those of younger persons. To explain the different chances, the job search literature has largely focused on the job search behavior of unemployed individuals. Based on job search models, we propose that not only job search behavior, but also wage setting behavior, attitudinal variables and personal variables impact the difference in reemployment opportunities. Besides gaining insight into which variables explain the difference in reemployment opportunities, we also test how much of the difference each of these variables explains. We do this by drawing on a decomposition analysis. Using data from 647 recently unemployed, we find that about one third of the reemployment gap can be explained by the variables suggested by job search models, mostly in terms of age differences in search behavior, educational levels and reservation wage. Hence, about 70 % can be ascribed to other factors, such as employer preferences for those aged between 18 and 49. Implications of these results for theory, policy and practice are discussed. 相似文献

The previously unknown asymptotic distribution of Cook's distance in polytomous logistic regression is established as a linear combination of independent chi‐square random variables with one degree of freedom. An exhaustive approach to the analysis of influential covariates is developed and a new measure for the accuracy of predictions based on such a distribution is provided. Two examples with real data sets (one with continuous covariates and the other with both qualitative and quantitative covariates) are presented to illustrate the approach developed. 相似文献

Mexican‐origin families are a large and rapidly increasing subgroup of the U.S. population, but they remain underrepresented in family scholarship. This paper introduces a special section of four papers on Mexican‐origin families designed to contribute to the advancement of research on how cultural, family, and gender socialization processes unfold across key developmental periods and life transitions in this cultural context. Two longitudinal studies of Mexican‐origin families provided the data for these four papers: (a) The Juntos Project, an 8‐year longitudinal study of mothers, fathers, and adolescent sibling pairs in 246 Mexican‐origin families; and (b) The Supporting MAMI Project, a study following 204 adolescent mothers and their mother figures from the third trimester of pregnancy through their young children's 5th birthdays. In this introductory paper, we highlight four themes, including (a) differential acculturation and reciprocal socialization, (b) interdependence in families, (c) the intersection of culture and gender, and (d) methodological issues. We end with suggestions for future research. 相似文献

We assessed 2 forms of agreement between mothers' and fathers' socially desirable responding in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand and the United States (N = 1110 families). Mothers and fathers in all 9 countries reported socially desirable responding in the upper half of the distribution, and countries varied minimally (but China was higher than the cross‐country grand mean and Sweden lower). Mothers and fathers did not differ in reported levels of socially desirable responding, and mothers' and fathers' socially desirable responding were largely uncorrelated. With one exception, mothers' and fathers' socially desirable responding were similarly correlated with self‐perceptions of parenting, and correlations varied somewhat across countries. These findings are set in a discussion of socially desirable responding, cultural psychology and family systems. 相似文献
