Child‐Care Usage and Mother‐Infant “Quality Time”

Mothers' time‐use patterns were compared in families in which infants spent more than 30 hours per week in child care (In‐Care group; n= 143) versus 0 hours per week (At‐Home group; n= 183) from birth to 6 months of age. In‐Care group mothers spent about 12 fewer hours per week interacting with their infants, for about 32% less time; fathers of these infants were more involved in caregiving. The groups did not differ in the quality of mother‐infant interaction. In the In‐Care group, quantity of interaction was related to greater separation anxiety and concerns about effects of maternal employment. Time‐use data were not related to child outcomes at 15 months of age. Results suggest that the effect of extensive time spent apart on the quantity and quality of mother‐infant interaction may be smaller than anticipated.

Using a computer simulation game to teach family time use concepts

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.     

Some quantitative concepts of value and utility from a utilitarian point of view

This paper clarifies and interprets some basic quantitative concepts of value, utility and utility function from a utilitarian point of view. First, I discuss the question as to whether value is objective or subjective. I hold that value is subjective and statistical in nature (although from the various subjective values of a certain object a norm can usually be obtained). Second, I emphasize the distinction between use value and exchange value in relation to utility. Third, I propose a law of diminishing incremental interest, which refers to the incremental (marginal) utility of money. Fourth, I identify the utility of money with the von Neumann-Morgenstern utility. Fifth, I question the necessity of the usual normalization of utility functions and the restricted linear transformation (and the consequent concept of strategic equivalence). Sixth, I discuss in detail the terminal values and utilities of a utility function from a philosophical rather than mathematical point of view, particularly the boundedness of a utility function and the magnitudes of V ₀ and U ₀. Finally, I conclude that, in order to be able to have interpersonal comparisons of utility, utility should have the same dimension as value rather than no dimension, and the normalization problem should be reconsidered in the light of terminal values and utilities.     

房地分离：宅基地流转之钥——以宅基地使用权继承之困局为切入点

尽管具有一定保障性,但宅基地制度的首要目标在于经济管理,其表面上强调“户有所居”,实际是“户有定居”。宅基地上使用权所承载的管理性与农民自费建造农房所有权的私权性,存在内在的矛盾,不应适用房地一体规则,因为后者遵循着传统民法应对市场交易的基本逻辑。自然资源部所发布的文件明确了宅基地使用权可以由城镇居民继承,内核乃是基于房地一体,以房屋所有权的可继承带动宅基地使用权的可继承,颇为冒进。宅基地上所有权与房屋使用权应当分离,这将为宅基地的流转与乡村振兴提供新的契机：农房的自由流转加上宅基地使用权的农民保有,将最大限度地在现有阶段实现市场与制度的有机契合;对于取得农房的所有权人,在房地分离之下,可以借助对宅基地使用权的法定租赁来设计合理的权利结构。     

大数据时代个人信息法益刑法保护的应然转向——以规制非法使用个人信息为重点

我国《刑法》第253条之一侵犯公民个人信息罪规定的行为类型仅限于非法获取、出售或提供个人信息代表的转移行为,没有将非法使用个人信息行为纳入规制范围,造成刑事规制出现漏洞,体现了将个人信息自主片面地理解为转移自主、忽视使用自主的法益认识缺陷,进而仅以防范非法转移个人信息为入罪逻辑,使得个人信息法益刑法保护不周延。当前个人信息已然成为网络犯罪中的关键要素,非法使用个人信息现象愈演愈烈,侵犯公民个人信息犯罪已经逐渐形成“提供者—中间商—非法使用”的完整黑色产业链,各环节分工明确、组织严密,通过非法使用个人信息实施违法犯罪活动,进而变现牟利是诱发个人信息泛在泄露以及违法交易激增的根源,刑法单纯打击制裁非法转移个人信息行为只能是治标之策,导致侵犯个人信息犯罪刑事治理效果欠佳。随着进入大数据深度挖掘应用阶段,数字经济蓬勃发展背景下根植于个人信息的人身性、财产性、公共性等复合法益属性的使用价值日益凸显,使得个人信息使用自主相较于个人信息转移自主更具核心法益地位,个人信息刑法保护的重点理应从转移环节转向使用环节。非法使用个人信息属于下游行为,对公民的人身财产安全以及社会管理秩序造成极大损害或威胁,与处...
