Headed Toward Equality? Housework Change in Comparative Perspective

This paper examines gendered housework in the larger context of comparative social change, asking specifically whether cross‐national differences in domestic labor patterns converge over time. Our analysis of data from 13 countries (N = 11,065) from the 1994 and 2002 International Social Survey Program (ISSP) confirmed that social context matters in shaping couples' division of labor at home, but also showed that context affects patterns of change. Our results suggested that, compared to the most egalitarian countries, the shift in housework patterns was greatest among the most traditional countries. This provides support for the thesis of cultural convergence, but the evidence did not suggest that such convergence will lead to complete equality in the foreseeable future.     

The flood algorithm—a multivariate, self-organizing-map-based, robust location and covariance estimator

Self-organizing maps (SOMs) introduced by Kohonen (Biol. Cybern. 43(1):59–69, 1982) are well-known in the field of artificial neural networks. The way SOMs are performing is very intuitive, leading to great popularity and numerous applications (related to statistics: classification, clustering). The result of the unsupervised learning process performed by SOMs is a non-linear, low-dimensional projection of the high-dimensional input data, that preserves certain features of the underlying data, e.g. the topology and probability distribution (Lee and Verleysen in Nonlinear Dimensionality Reduction, Springer, 2007; Kohonen in Self-organizing Maps, 3rd edn., Springer, 2001).

Effects of international student exchange on pre-service teachers: a quasi-experimental study

This contribution provides empirical answers to the question of how teaching-specific competencies develop during participation in an international student exchange programme. The quantitative analyses of this quasi-experimental study suggest that, generally speaking, no specific developments occur during an exchange experience. These findings contradict the majority of existing literature. Possible reasons for this divergence are discussed. The interpretation of the results suggests future research should focus on the key question of pre-conditions for productive exchange experiences.     

Rights or Identity? Naturalization Processes among “Labor Migrants” in Germany

The determinants of the decision to naturalize for first and second generation “labor migrants” in Germany are examined. We assume that Turkish migrants' comparatively high naturalization rate cannot be explained by the legal advantages they gain by naturalizing. We argue instead that naturalization offers an opportunity for individual upward mobility to Turkish migrants who have achieved a high level of individual assimilation. Using data from the GSOEP, we show that individual assimilation does in fact promote naturalization for Turkish migrants, but not for members of other ethnic groups, which generally have higher status within German society.     

Women’s Timing of Receipt of Social Security Retirement Benefits

The 2000–2006 waves of Health and Retirement Study data were used to estimate the effects of human capital characteristics and income sources on women’s timing of receipt of Social Security retirement benefits. Using logistic regression, the likelihood of early election of benefits was increased by earnings regardless of marital status; and, for married women, by husband’s age being greater than wife’s, and by other income. For married women, education decreased the likelihood of electing early benefits. For unmarried women, IRA/annuity income reduced the likelihood of early receipt of benefits. Using multinomial logistic regression, the likelihood of combinations of expected and actual benefit receipt options were estimated. A greater percentage of married, compared to unmarried, women expected and elected early benefits.
