沿海经济发达区种植业集约度评价研究

评价区域种植业集约化程度,对于研究区域种植业持续健康发展对策建议具有重要的理论和实践意义。本研究采用种植业集约度评价种植业投入产出总体集约化程度,采用指数和法评价区域种植业集约度。以山东省寿光市为研究区,选取确定了11个评价指标及其评分分级标准和权重,评价结果表明:寿光市经过24年(1980-2004)的时间,种植业集约度大幅度提高,集约度指数由1980年的46.9上升到2004年的87.3,增长幅度为86.1%,集约度指数等级由6级提高到1级。2004年寿光市种植业集约度明显高于全国和山东省平均水平,集约度指数高于全国平均水平29.3%,高出3个等级;高于山东省平均水平8.8%,高出1个等级。

Partner Choice and the Differential Retreat From Marriage

The contemporary retreat from marriage in the United States has had a differential impact across socioeconomic and racial groups. Here, 1990 marriage rates and propensities for Virginia, North Carolina, and Wisconsin are analyzed regarding (a) the likelihood that persons in different groups ever marry and (b) patterns of partner choice with respect to race and educational level. Marriage remains strong in most race‐education groups but is substantially lower among Blacks and among those with less than 12 years of education. Patterns of partner choice have shifted to show greater symmetry between the educational levels of brides and grooms. Changes have been modest with regard to the level and pattern of interracial (Black‐White) marriage. Marriage is increasingly a union of equals, but a union chosen more by Whites than by Blacks and more by the well educated than by the poorly educated.

The Division of Household Labor in Germany and Israel

We compare the patterns of household division of labor in Germany and Israel—two countries that share key elements of the corporatist welfare regime but differ in their gender regimes—and evaluate several hypotheses using data from the 2002 International Social Survey Program. Although time constraints and relative resources affect the division of household labor and women’s housework in both societies, we find that in Germany the gender order of household labor is more rigid, whereas in Israel the spouses’ linked labor market status exerts distinctive effects. We also find significant relationships between gender ideology and the division of household labor. We discuss the theoretical advantages of approaching the comparative study of gender inequality from the vantage point of family and gender regimes.
