Abstract. Most research on the relationship between health and socio‐economic status (SES) controls for age or investigates the relationship for a particular age range. This paper, however, examines the effect of SES on health across different age groups. Using data from the German Socio‐Economic Panel and controlling for health–SES endogeneity, we find that the health–income relationship does vary across the life cycle and between genders and different labor force status, with the impact of income on health relatively more pronounced for younger cohorts. The unemployed also have lower levels of health at all levels of income. 相似文献

本文利用中国29个省份20年的面板数据,探讨了人口结构变化对储蓄、投资和经济增长的影响。我们将人口结构指标引入传统的经济增长模型中,并用固定效应模型和SYS-GMM计量方法分别测算其对储蓄、投资和经济增长的效应。考虑到老年抚养比在经济增长方程的内生性,我们还将滞后30年的就业人数比率作为工具变量来识别老年抚养比对经济增长的因果效应。结果显示老年抚养率对储蓄、投资和经济增长存在显著的正相关。人口增长率对储蓄和投资有着负相关,但对经济增长没有影响。工作年龄人口比率对储蓄率存在负相关,对投资和经济增长存在正向影响但估计的回归系数不显著。在加入其它制度和人口变量之后回归结果依然稳定。 相似文献

For right-censored data, the accelerated failure time (AFT) model is an alternative to the commonly used proportional hazards regression model. It is a linear model for the (log-transformed) outcome of interest, and is particularly useful for censored outcomes that are not time-to-event, such as laboratory measurements. We provide a general and easily computable definition of the R2 measure of explained variation under the AFT model for right-censored data. We study its behavior under different censoring scenarios and under different error distributions; in particular, we also study its robustness when the parametric error distribution is misspecified. Based on Monte Carlo investigation results, we recommend the log-normal distribution as a robust error distribution to be used in practice for the parametric AFT model, when the R2 measure is of interest. We apply our methodology to an alcohol consumption during pregnancy data set from Ukraine. 相似文献

In this paper, the limit distribution of the least squares estimator for mildly explosive autoregressive models with strong mixing innovations is established, which is shown to be Cauchy as in the iid case. The result is applied to identify the onset and the end of an explosive period of an econometric time series. Simulations and data analysis are also conducted to demonstrate the usefulness of the result. 相似文献

Chan CK. Hong Kong: workfare in the world's freest economy Int J Soc Welfare 2011: 20: 22–32 © 2009 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. Workfare was introduced in many countries to suppress welfare dependency and reduce social security expenditures. However, workfare was launched in Hong Kong when there was only a relatively small social security budget and its citizens still strongly adhered to the ideologies of self‐reliance. It was found that workfare has performed several functions in Hong Kong. First, by forcing unemployed claimants to give up benefits, Hong Kong has been able to save on social security expenditures. Second, workfare has combined with Hong Kong's semi‐democratic polity so that extremely stigmatising welfare measures have been implemented. Third, it has pushed poor citizens into the labour market without having any protection over wages and working hours. Thus, the combination of workfare and a semi‐democratic polity has successfully suppressed Hong Kong's welfare demands and strengthened its self‐help spirit. As a result, Hong Kong's minimal social security scheme and its low tax policy have been maintained. 相似文献

From Transitional to Permanent Uncertainty: Employability of Middle‐aged Workers in Hong Kong 下载免费PDF全文
Raymond K.H. Chan 《Asian Social Work and Policy Review》2016,10(3):358-374
Since the 1990s, Hong Kong has experienced increasing economic uncertainty. Middle‐aged workers, who often have little formal education and limited skills, have been the first casualties of economic restructuring. Initially, their unemployment was considered transitional. Limited government‐sponsored retraining programs were expected to improve their employability. Subsequent economic crises, however, have undercut the hopes of both workers and policy‐makers. Despite improvements in the job market since the mid‐2000s, the belief that unemployment was transitional has been replaced by a permanent state of uncertainty and consequent anxiety. Flexibility is considered the key to sustaining economic growth, and would relieve the insecurity and anxiety associated with unemployment. Policies have been modified, but they are still based on a narrowly defined concept of individual employability, which consolidates the sense of uncertainty. To address the factors contributing to the perception of permanent uncertainty among middle‐aged workers, we advocate a pragmatic approach that takes reference from the notion of flexicurity to mitigate this sense of uncertainty. 相似文献

AbstractThis essay explores a series of sovereign ‘machines’ – slaves, puppets, automata – in political theory from Benjamin to Agamben. It is now well-documented that the philosophical question of ‘the machine’ – of whether a complex system requires a human operator or whether it can function autonomously – is also a crucial political question that haunts every discussion of sovereignty from Hobbes onwards. However, my wager in what follows is that this machine is not just a metaphor for a metaphysical situation – whether it be rationality (Hobbes), bureaucratization (Weber), neutralization (Schmitt), historicism (Benjamin) or governmentality (Foucault) – but a material phenomenon that carries transformative political promise and threat. To summarize the argument of this essay, I contend that ‘sovereign machines’ like slavery (Aristotle, Hegel, Kojève, Agamben), puppets, automata or clockwork (Descartes, Hobbes, Schmitt, Benjamin, Derrida), lens, optics and mirrors (Hobbes, Kantorowicz, Benjamin, Lacan, Foucault) and so on do not merely reflect but change our understanding of the causal relationship between sovereignty and governmentality, decision and norm, exception and rule. If the self-appointed task of the modern political theorist has so often been to obtain or regain sovereignty of, or over, the machine – to jam its gears – I seek to expose what the later Derrida calls the ‘machine’ of sovereignty itself. In conclusion, I argue that political theory’s attempt to reveal or retroactively invent the sovereign person at the heart of the machine only ends up revealing the sovereign machine at the heart of the person. What – if anything – is really inside the machine of sovereignty? 相似文献

This study investigated hope as a protective factor buffering the relationships between parenting stress and well-being among a sample of parents identified at moderate to high risk for child maltreatment. Two hundred parents were recruited from a nonprofit organization providing secondary and tertiary child maltreatment prevention programs. Results of the analyses showed that parental stress was negatively associated with subjective and emotional well-being. Hope was positively correlated with well-being and negatively associated with parenting stress. Hierarchical regression analyses showed that hope had a significant incremental relationship to well-being and that the negative effects of parenting stress fell below statistical significance. These findings provide preliminary support for hope as a coping resource social workers can target when working with parents in the prevention of child maltreatment. 相似文献

This article adopts a processual and relational approach to study food remembrance and investigates how different ways of appropriating food reveal the politics of identities in Hong Kong. It examines how food memories reveal relationships between the past and the present, reflect epochal transformation, and mark changing identities of various groups of people through new ways of appropriations. It takes the case study of pancai, a special banquet food for the villagers in the New Territories of Hong Kong, to examine the relationships between food and identities. This article investigates how pancai is remembered, popularized, and reinvented with different variations and embodies shifting meanings for the New Territories inhabitants as well as other Hong Kong people in changing socioeconomic and political environments. Pancai has been imbued with multiple layers of significance, involving linkages between local and national, emigration and Chineseness, urbanization and rural heritage, as well as decolonization and identity politics. As identities are by nature negotiable, situational, and fluidic, pancai's multiple layers of meanings correspond to different levels of identities—identities of the New Territories inhabitants, the rest of the Hong Kong people, and the mainland Chinese. 相似文献

This paper elaborates the notion of mediated action through a comparison of group improvisational performance and the product‐oriented creative domains studied by psychology. Semiotically mediated interaction is central to both forms of creativity: in group improvisation, the interaction is parallel and simultaneous, communication between performers is mediated by musical or verbal symbolic structures, and is thus synchronies in product‐oriented creative domains, interaction between creating individuals is mediated by ostensible products in the domain, the interaction is over long time spans, and thus is historical or diachronic. After presenting a model of mediated action, six interactional dimensions of contrast are described which are characteristic of both synchronic and diachronic creative interaction. By demonstrating these processual parallels between synchronic and diachronic creativity, the model suggests that the study of performance has several implications for the broader study of creativity. The focus on processes of symbolic interaction represents an application of the mediated action concept to both product creativity and improvisational performance. 相似文献
