Hard Living,Perceived Entitlement to a Great Marriage,and Marital Dissolution

Using the two waves of the National Survey of Families and Households (NSFH), we examine the effects on marital dissolution of couple's gender attitudes, perceived unfairness, marital disagreements, and relationship alternatives, exploring whether these dimensions of marriage influence marital dissolution, net of serious forms of hardship commonly noted in divorce research. With event history methods, we find that husbands’, but not wives’, perceived disagreements and alternatives are associated with higher odds of marital dissolution, though couples' marital happiness strongly mediates the effects of husbands' dissatisfaction. Wives' traditional attitudes are associated with lower odds and husbands' with higher odds of marital dissolution. We find no significant effects of unfairness perceptions on divorce. A nonviolent relationship is associated with lower odds of marital dissolution, but accumulated assets and debt and husbands' drug or alcohol abuse are not associated significantly with marital dissolution. Our analysis contributes to divorce research by demonstrating the importance of gender attitudes and low physical conflict and by showing that instances of perceived dissatisfaction might not matter for couples as much as marital happiness as an influence on divorce.     

Union Transitions Among Cohabitors: The Significance of Relationship Assessments and Expectations

Data from both waves of the National Survey of Families and Households (NSFH) were used to estimate the effects of couple‐level measures of cohabitors' relationship assessments and expectations on their union transitions. Although positive relationship assessments deterred separation, they did not hasten entry into marriage. Female partners' negative assessments of the relationship increased the odds of separation, whereas such reports among male partners weakened the odds of marriage. Plans to marry were positively associated with marriage entry, but this effect was considerably larger for White couples than it was for Black couples. Cohabitors' expectations that their union would dissolve were also associated with union transitions. When both partners reported an even to high chance of dissolution, the odds of marriage were low, and the odds of separation were high. Cohabitors' own relationship assessments and expectations are significant predictors of their union outcomes.

论分权理念在政府人力资源开发中的运用

随着社会实践的不断发展,传统人事行政管理体制下政府权力运作过于集中的弊端日益暴露出来。现代政府在人力资源开发过程中,应积极转变不合时宜的集权范式,适度分权,从而促进政府人力资源的充分开发、使用和政府工作效率的提高。为此有必要坚持分权理念,在政府人力资源开发中充分运用分权理念的主要原则、环节和方式。     

ANSYS在张力膜结构找形分析中的应用

找形分析是膜结构与其它一般刚性结构在计算上的一个显著区别。这个过程是一个强烈几何非线性的计算过程,进行编程求解有一定难度。文章介绍了膜结构找形的计算理论,并借助通用有限元软件ANSYS对膜结构的找形问题进行叙述,最后给出找形算例,证明采用ANSYS进行膜结构的找形计算是切实可行的。     

Distress in Emerging Adults: Further Evaluation of the Painful Feelings About Divorce Scale

Young adults from divorced families experience clear emotional distress despite most not meeting diagnostic criteria for emotional disorders. Laumann-Billings and Emery (2000) developed the Painful Feelings About Divorce (PFAD) scale to assess the emotional distress emerging adults feel regarding childhood parental divorce. The study sample is undergraduates predominately between the ages of 18 and 22. This study adds to the literature by (a) further demonstrating the PFAD scale reliability and validity, (b) including participants with both divorced and separated but never married parents, and (c) assessing generalizability of the PFAD with a more diverse socioeconomic sample.
