Determinants of housing quality: A comparison of white,African-American,and Hispanic single-parent women

This study examines housing quality among three groups of single-parent women: white, African-American, and Hispanic. Three indicators of housing quality—crowding, affordability, and satisfaction—are used to discover the extent to which these groups experience housing problems. This study also explores differences and similarities in the factors that precipitate problems in housing quality for these three groups of single parents. Findings suggest important differences and similarities in the nature of housing quality problems among white, African-American, and Hispanic single-parent women. The specified variables explained about 20% of the variance in crowding, housing affordability, and housing satisfaction. On measures of objective and subjective housing quality, white single mothers are better housed than their African-American or Hispanic counterparts. Hispanic single mothers have the largest housing cost burden and average more persons per household than the other groups. African-Americans are twice as likely as either group to live in low-quality housing and reported the lowest average satisfaction with their housing. Her research interests include housing and neighborhood assessment and women and public policy issues. She has recently published articles inUrban Affairs Quarterly andHousing and Society on housing and neighborhood assessment criteria among black urban households and the housing cost burden of various groups of female-headed households. She received her Ph.D. from Ohio State University. Her research interests include the housing adjustment behavior of women and public policy. She has recently completed her thesis on the role of noncustodial parents in determining the quality of life of their children. She is also the recipient of the Tessie Agan Award for research excellence from the American Association of Housing Educators for a paper titled “Unterstanding Constraints and Residential Satisfaction among Low-Income Single-Parent Families.”

Compatibility,Leisure, and Satisfaction in Marital Relationships

This study challenges the prevailing view that marital companionship promotes marital satisfaction. By following a cohort of married couples for over a decade and by incorporating several methodological improvements—such as refining the measurement of marital satisfaction, determining how much spouses enjoy doing the leisure activities they pursue together and apart, and using diary data to portray marital leisure patterns—we found that the association between companionship and satisfaction is less robust than previously believed, and that it depends on how often spouses pursue activities that reflect their own and their partner's leisure preferences. Over time, involvement in leisure liked by husbands but disliked by wives, whether as a couple or by husbands alone, is both a cause and a consequence of wives' dissatisfaction.

中国民事诉讼费用负担制度的法经济学思考

当事人之间诉讼费用负担和国家对审判成本负担的划分影响着当事人诉讼行为的选择。目前中国民事诉讼费用负担制度存在着制度供给不足、缺少救济措施、权利分布不均衡和国家承担公共成本太低等问题,因此健全中国民事诉讼费用负担制度,制定可行的救济措施,并对民事诉讼费用负担判决实行监督,实施法院独立预算等措施,才是解决民事诉讼费用负担问题的根本途径。

论跨国公司以消费者为中心的分销渠道的构建

跨国公司要在我国市场取得成功，必须更加着重于开发针对我国“大众市场”的战略，而减少对竞争激烈、市场趋于饱和的顶级城市的关注。跨国公司构建以消费者为中心的分销渠道应与消费者保持零距离接触，向终端市场靠拢，实现分销渠道扁平化，有利于与同一个市场上优势明显的本地公司进行有效竞争。从消费者的需求出发，实现本土化经营，以便更好地了解以及服务当地客户，提高客户的满意度。
