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.

李商隐与屈原悲剧比较论

李商隐通过撷取屈赋文句和楚辞视野表达对屈原悲剧性的理解与认同,行似折射神合与“端午·楚地”的时空交点产生的历史机缘使二人悲剧感得以贯通,但在文本书写和情意表达上又有不同,包括娱忧与饮酒文字、惯性感伤与诗歌转折结构、抑郁排遣与幻境描写、仕隐二重心态以及取象、造境、诗歌样式等方面的差异,显示出不同的悲剧形态:屈原是崇高的壮美,李商隐是哀婉的秀美。差异的成因包括地位悬殊、宗教影响、最后的结局、后人的接受态度以及生命力感的刚韧之别。
