四种老龄化理念及其政策蕴意

在老龄化问题研究中,健康老龄化、积极老龄化、成功老龄化和生产性老龄化,这四种理念具有不同的内涵。在结合地方养老服务创新案例分析四种老龄化理念的相互关系及其政策蕴意的基础上,运用“生活质量-社会质量”视角,评估健康老龄化和成功老龄化在提升老年群体生活质量方面的效用,探讨生产性老龄化和积极老龄化对提升社会质量的意义,从而深化人们对各种养老理念的理解,将老龄化的问题延展至老年照顾之外的参与和增能方面,丰富养老政策的内容和内涵,为发展老年友好型社会提供政策路径。     

国际经验和中国社会福利体系的发展

一、从国际经验看社会福利体系发展的趋势 纵观欧美发达国家在20世纪所经历的社会福利体系发展进程,我们可以看到,当经济发展的水平超越了人均国民产值6000美元的阶段之后,政府在社会福利方面的投入将会逐渐加大,并开始构建起各自的福利国家体系.在英国,其人均GDP在上世纪40年代已达到6000美元之上(以国际元即G-KD美元作为衡量单位),而正是在这个时候,贝弗里奇提出了"福利国家"的理念.

Signed compound poisson integer-valued GARCH processes

Abstract

We propose signed compound Poisson integer-valued GARCH processes for the modeling of the difference of count time series data. We investigate the theoretical properties of these processes and we state their ergodicity and stationarity under mild conditions. We discuss the conditional maximum likelihood estimator when the series appearing in the difference are INGARCH with geometric distribution and explore its finite sample properties in a simulation study. Two real data examples illustrate this methodology.     

INTERNATIONAL CURRENCY SUBSTITUTION AND SEIGNIORAGE IN A SIMPLE MODEL OF MONEY

This paper investigates the economic signcance of currency substitution using a small, open economy model of money. The main result is that in a low-inflation economy the seigniorage-maximizing inflation rate can be quite large despite a very high elasticity of currency substitution when the share of foreign real balances in producing domestic liquidity services is small (as some recent econometric estimates indicate in the case of Canada). This suggests that currency substitution is likely to be of second-order importance to policymakers in a low-inflation economy where foreign real balances provide economically small domestic liquidity services.     

Identity and Disruptiveness in Boys: Longitudinal Perspectives

After more than 30 years of research on identity, the links between identity and disruptive behaviors are not clear. This study compared the identity formation of boys with stable disruptive behaviors from age 6 to age 15 (n = 16), with the identity formation of boys that were never disruptive during the same period (n = 25). All boys came from low socio-economic status families. At age 9 and 11, identity was assessed with the The Self-Perception Profile for Children (Harter, 1985). At age 15, identity was assessed with the Extended Objective Measure of Ego Identity Status (Adams, Bennion, & Huh, 1989) and two scales of the Offer Self-Image Questionnaire (Offer, Ostrov, & Howard, 1981). Differences between disruptive and non-disruptive boys were found only for behavior in childhood and identity in ideological domains at age 15. Explanations for the weakness of the link between identity and disruptiveness are discussed.     

How leader humility helps teams to be humbler,psychologically stronger,and more effective: A moderated mediation model

We hypothesize that (a) the level of humility expressed by leaders predicts team performance through, serially, team humility and team PsyCap, and (b) the strength (i.e., consensus within the team) of the leader humility, team humility and team PsyCap moderates the paths of that hypothesized model. A sample comprising 82 teams (82 leaders; 332 team members) was collected. Team members reported leader humility, team humility and team PsyCap. Leaders reported team performance. To handle the risks of common method bias, each mediating path of the hypothesized model is based on data from two different subsamples within each team. Our model's most novel theoretical contribution is the (moderated mediated) connection between leader humility, collective humility, and team PsyCap, and this was consistently supported in our data. Our inconsistent findings dealing with the relationship between team PsyCap and performance is well established in the literature and our results in both sub-samples were in the theorized direction. The study contributes to understand why, how and when humble leaders are more effective.     

Predictors of Adolescent Participation in Organized Activities: A Five‐Year Longitudinal Study

This study examined (a) growth curves of youth participation in sports, performance and fine arts, and youth clubs throughout the high school years and (b) the associations between a series of predictors and the initial participation rates and growth over time. The predictors included individual, friend, and family factors. The moderating effect of youths' gender was also examined. Study participants were 272 youths (55% girls, M_age=12.4 years) and their parents. The predictors were assessed in Grade 6 and were based on reports by youths, parents, teachers, and classmates. Participation in organized activities was assessed annually from Grades 7 to 10. Altogether, the findings revealed that participation in sports, performance and fine arts, and youth clubs remains stable across the high school years. However, interindividual differences were found in the participation growth curves. This variation was predicted by individual, friend, and family factors, mostly with respect to sports activities.
