Pension Participation: Do Parents Transmit Time Preference? 总被引:1,自引:0,他引:1
Elena Gouskova Ngina Chiteji Frank Stafford 《Journal of Family and Economic Issues》2010,31(2):138-150
A wide range of economic and health behaviors are influenced by individuals’ attitudes toward the future—including investments
in human capital, health capital and financial capital. Intergenerational correlations in such behaviors suggest an important
role the family may play in transmitting time preferences to children. This article presents a model of parental investment
in future-oriented capital, where parents shape their children’s time preference rates. The research identifies a dual role
for a parent’s time preference rate in the process of shaping the offspring’s attitude toward the future, and discusses paths
through which parents may socialize children to be patient. The model’s implications are studied by investigating the parent–child
correlation in pension participation using data from the Panel Study of Income Dynamics 相似文献

The article presents the results of a comparative study of human resource development (HRD) in two groups of knowledge-intensive firms: those working in the information technology (IT) field and in advertising/public relations (PR) field. One hundred Russian medium-sized enterprises participated in the study. The questionnaire was developed on the basis of the European quality standard ‘Investors in People’. The study findings suggested that the differences in HR practices aimed at personnel development between two groups of companies were statistically significant. Thus, in the advertising/PR companies, HRD practices were used more actively and effectively, with particular emphasis on providing timely feedback and involving employees in the decision-making process. In IT companies, formal assessment tools were used more often, while in advertising/PR companies, more informal and individualized approaches were more prevalent. 相似文献

A risk assessment was performed to incorporate uncertainty in food processing conditions to develop a risk-based sterilization process design. The focus of this analysis was uncertainty associated with heterogeneous food products. Quartered button mushrooms were the chosen food product because it represents the most typical type. A model for sterilization of spherical particles was utilized, and each parameter's uncertainty was characterized for use under Monte Carlo simulation. Various particle distributions and fluid types were compared. The output of the model was the required sterilization time to achieve the target sterilization conditions with 95% probability. This value was then used to determine the mean fluid velocity for a given tube length. Finally, the output from the model was analyzed to determine the confidence in output based on uncertainty in the input parameters. The model was more sensitive to variation in particle size distribution than fluid type for power-law fluids. The 90% confidence interval included a holding time range of 1 min. With a 95% confidence level that only 8% of the data will be below the target sterilization conditions, a maximum of 9% of the data were expected to achieve double the target level. The results of such an analysis would be useful for management decisions concerning the design of aseptic food processing operations. 相似文献

Spatial and temporal databases that integrate urban tree inventories and soil quality information are needed for modern-day sustainable urban forest management. The objective of this study was to demonstrate the usefulness of low-cost and widely-available technology, such as global positioning system (GPS)–enabled cameras to photo-document sites and cloud-based products and services (Google Picasa and Fusion Tables), to aid in developing sustainable street tree management programs. Google Fusion Tables provide a cloud platform to store, share and map urban tree and soil data over time using internet connected computers, tablets or mobile devices. Although indicators of urban soil quality and best methods to assess it are not yet standardized, we demonstrate here promising indicators that are both useful and easy to incorporate into spatial and temporal databases of trees managed in urban environments. By utilizing technology, we demonstrate that site-specific urban soil quality indicators can be used together with readily-available soil rating systems specific to different plant types as a means to better evaluate and manage conditions for optimal street tree growth and health. 相似文献

The education system's responsibility for social workers to be is a central argument in the academic arena. The purpose of the article is to present an innovative perspective about social work education promoted for several years in the Catholic University in Milan. The education experience with students, social workers to be, gave life to a particular workshop ‘Social Work Orientation’ characterized by different and innovative activities. The experience presented focuses on relational principles such as empowerment, peer facilitation, involvement of service users, and facilitation, following the idea that teaching and learning could be a simultaneous process. Revealing is the experience of ‘service users as professors’, a meeting day in the university between students and service users, a sharing of life stories and relationships. The future social workers learn from the service users, accustoming themselves to considering the service users as people able to cope with their life situations even before enrichment with all the professional tools. The feedback collected about this experience (from students, service users, and professors) shows that the possibility to experiment from the beginning in this approach facilitates the students to become social workers oriented to empowerment and relational processes. 相似文献

People form essentialist beliefs about social categories as a strategy to organize their world and to make sense of the similarities and differences between different categories. This research examines four dimensions of essentialist thinking (biological basis, immutability, clarity of discreteness and informativeness) across different sexuality-related categories. Specifically, the categories of gays, lesbians, transsexuals, paedophiles, rapists and prostitutes were studied. Results show that essentialist beliefs of the six categories vary across dimensions and that essentialist dimensions function independently. Therefore, we discuss the relative usefulness of taking a global measurement as opposed to analysing the dimensions of essentialism separately. 相似文献
