家庭文化对于历史小说家的审美趣味和历史观念具有重要影响,家学传统给予历史小说家的文化熏陶对于历史小说写作具有重要意义,情感的苦乐体验使作家对历史小说如何以史鉴今重塑中国文化和民族精神有着独特理解,但家庭文化的负面因素也造成了历史小说的缺憾和不足。  相似文献

This two-part study applied an ecocultural perspective to socialization of daily and long-term goals in low-income Mexican-American and European-American families with children in third, fifth, and seventh grades. The first part of the study examined family members' participation and parents' socialization goals and guidance strategies for their children's daily household chores and homework activities. The second part of the study examined parents' long-term aspirations and guidance strategies for their children's educational, vocational, and moral development. For daily activities, results showed that in Mexican-American families both parents and siblings played important roles, whereas in European-American families parents were the primary socialization agents. As predicted, in both groups parents' expertise influenced their guidance strategies. Finally, Mexican-American and European-American parents differed in their relative endorsement of gender, relational, and self-reliance goals for household chores. For long-term goals, parents in both groups held high educational, vocational, and moral aspirations for their children. However, some parents of seventh-graders had lower educational and vocational aspirations than those of fifth- and third-graders. Although expertise consistently influenced Mexican-American parents' guidance strategies, the pattern for European-American parents was mixed. The discussion highlights between- and within-group differences in daily and long-term socialization practices with an emphasis on resources and vulnerabilities in the families.  相似文献

A computer simulation game designed to give students insights into family time use concepts has been used in an introductory family resource management class at Ohio State University and other universities. The game allows for planning for time use changes over the family life cycle. The game can give students insights into economic and sociological models of time use. It is possible that future versions of the game could be used in family counseling.His research interests include derivation of optimal decision-making rules for families and family financial management.Her research interests include financial management over the life course including financial ratios, baby boomers, and retirement. She received her Ph.D. in 1993 from The Ohio State University in Family Resource Management.His research interests include the time trade-offs made between couples, financial planning over the life cycle, and the interaction of time and money between families and their home-based businesses. He received his Ph.D. in 1993 from The Ohio State University in Family Resource Management.  相似文献

家族企业积极引入并利用非家族资本时,CEO人选对其职业化经营和现代化转型具有重要促进作用。基于2004—2017年中国2065家上市家族企业数据,从家族企业股东异质性的视角考察了其对家族企业CEO人选的影响。研究发现:家族大股东和非家族大股东投票权不对称性与职业经理人担任CEO显著负相关。非家族大股东类型越多,投票权不对称性与职业经理人担任CEO的负相关关系越强,但家族股东数量增加会抵消这种作用。横截面差异检验表明,不同类型非家族大股东对CEO人选具有不同的影响,未发生代际传承、由家族直接创办、审计质量较低的家族企业,投票权不对称性与职业经理人担任CEO之间的负相关关系更强。研究结论表明,家族式的非制度管理可能成为家族企业高质量发展的瓶颈,积极引入非家族股东并保持权力制衡有助于职业经理人的引入,这对于企业最终实现高质量发展意义重大。  相似文献

Generalized Leverage and its Applications   总被引:2,自引:0,他引:2  
The generalized leverage of an estimator is defined in regression models as a measure of the importance of individual observations. We derive a simple but powerful result, developing an explicit expression for leverage in a general M -estimation problem, of which the maximum likelihood problems are special cases. A variety of applications are considered, most notably to the exponential family non-linear models. The relationship between leverage and local influence is also discussed. Numerical examples are given to illustrate our results  相似文献

This study is a contribution to the development of family resource management scales, specifically financial management scales. Principal axis factor analysis, with varimax rotation, is used to assess underlying relationships in 23 family resource management variables related to time and money resources. Reliability and content, construct, and criterion-related validity of the scales are assessed. Two scales that are reliable and have some degree of validity are developed: frequency of financial problems and frequency of financial management. The scales could be used in future research, teaching, or counseling to organize financial management concepts.Preparation of this research was supported in part by the Illinois Agricultural Experiment Station. Data were collected in conjunction with the cooperative regional research project NC-182, Family Resource Utilization as a Factor in Determining Economic Well-Being of Rural Families. Cooperating states are Arizona, California, Illinois, Indiana, Iowa, Kansas, Michigan, and Minnesota.She received her Ph.D. from the University of Illinois; her current research interests include gender roles, family financial management, and economic well-being.Her current research interests include family financial management and consumer bankruptcy.

在食品安全威胁下,农户重新定义了“为自家生产”和“为市场生产”的差别化生产行为。基于经济理性行为假设认为农户存在以确保自家食品安全为动机的生存理性。根据在5省区收集的827份农村入户调研数据,对农户差别化生产行为进行具体分析,描述了差别化生产行为总体特征,并测量农户食品安全自我保护意识、威胁感知程度和信息渠道等因素。运用Probit模型验证了命题:以食品安全自我保护意识为特征的生存理性,支配了农户为确保自家消费安全而进行的差别化生产。  相似文献

家庭农场发展的多重动力机制分析   总被引:2,自引:0,他引:2  
基于政府、市场和农民家庭的综合分析视角,考察了家庭农场兴起的过程,系统揭示了家庭农场发展的多重动力机制。研究发现:政府推动农业规模经营的政策实践及市场化条件下农业规模效益的增长,构成为家庭农场发展的两个重要外部动力。但家庭农场的兴起和发展更是农民家庭借助政府和市场等外部条件变化,不断调整和优化其家庭劳动力的配置方式,从而最大化家庭收入以不断满足日益增长的家庭消费需求的结果。农民家庭构成为家庭农场发展的内在动力。家庭农场是农民家庭同政府和市场“互构”的结果,这也充分显示出了农民家庭经济组织的发展活力和发展前景,形塑了我国小规模农业的独特发展道路。  相似文献
