Remeasuring ageing in Hong Kong SAR; or ‘keeping the demographic window open’

Hong Kong SAR has among both the lowest fertility rates and highest life expectancy in the world. Under the current calculation of the Old Age Dependency Ratio (OADR), Hong Kong is, understandably, ageing extremely rapidly. This is a cause of significant concern among policy makers. However, OADR assumes that the entire population aged above 65 is both ‘old’ and ‘dependent’, neither of which is clearly defined, and that all aged below 65 are active in the labour force. Furthermore, because the rate is fundamentally based upon a European/North American model of pension and retirement it is arguably less appropriate to areas of the world where retirement ages are more fluid and pension systems less developed. We apply and extend a method for Hong Kong, designed by Sanderson and Scherbov, to ‘remeasure ageing’ by taking remaining life expectancy as the constant, rather than years lived by using projected life tables and 1 × 1 population projections. In doing so, we show that Sanderson and Scherbov’s new ‘prospective’ measurements of ageing more accurately reflect the increased longevity and vitality of Hong Kong’s population. Rather than passively accepting fate as a ‘rapidly ageing’ population, East Asian economies can be active in rethinking society’s relationship to work and other activities across the life-cycle. By adapting existing measurements to take into account the different welfare regimes in East Asia, we can radically alter the timeframe in which population ageing becomes ‘critical’. This allows more time to develop a more holistic life-course view of the relationship between work, longevity and fertility and to actively tackle ageing in an optimistic way.     

Assessment of the Refined Aging Semantic Differential: Recommendations for Enhancing Validity

The US population is aging. Traditional perspectives have emphasized that a substantial increase in the number of gerontological social workers is needed to care for this population. However, published evidence demonstrates that, along with population growth, economic and social factors must be taken into account before predicting future gerontological social work demand. Structural lag theory is introduced to explain how these factors affect the profession and may limit its presence in gerontological work settings. Recommendations are made to correct the lag, allowing the social work profession a more substantive voice in the aging enterprise.     

Child abuse in the context of domestic violence: prevalence, explanations, and practice implications

This article addresses the following questions: (a) How common is child abuse among domestically violent families? (b) Are there specific patterns of child abuse among domestically violent families? (c) What may explain occurrences of child abuse in domestically violent families? (d) How might domestic violence affect treatment for child abuse? We review research on child abuse in the context of domestic violence. We discuss implications of this research for service-delivery programs for domestically violent families.     

The differential effects of husbands' and wives' statuses on marital fertility

As an extension of prior subjectively-oriented studies that predicted couples' fertility decisions or outcomes by the expected costs and benefits of childbearing to husbands and wives, this article examines the differentiated effects of husbands' and wives' objective statuses on marital fertility, using the cumulative 1972–1990 GSS data. An interesting finding is that wives' education has a significant, negative effect on fertility while the effect of husbands' education is positive and statistically insignificant. This suggests that the generalization of the negative effect of education on fertility may be misleading if one fails to make a distinction between marital partners. Meanwhile, this study finds no significant differences in the effects of husbands' and wives' occupational and work statuses on fertility. By and large, the husbands' status variables add little information to the models explaining fertility. It is also found that the effects of husbands' and wives' statuses are contingent upon their relative education.     

A linear programming duality approach to analyzing strictly nonblocking <Emphasis Type="Italic">d</Emphasis>-ary multilog networks under general crosstalk constraints

When a switching network topology is used for constructing optical cross-connects, as in the circuit switching case, no two routes are allowed to share a link. However, if two routes share too many switching elements, then crosstalk introduced at those switching elements degrades signal quality. Vaez and Lea (IEEE Trans. Commun. 48:(2)316–323, 2000) introduced a parameter c which is the maximum number of distinct switching elements a route can share with other routes in the network. This is called the general crosstalk constraint. This paper presents a new method of analyzing strictly nonblocking multi-log networks under this general crosstalk constraint using linear programming duality.     

Work, employment, and mental illness: expanding the domain of Canadian social work

Despite established evidence that work and employment are an important component of recovery for people who experience mental illness, social work education in Canada seldom offers graduate training or courses on the significance of work in peoples' lives or on the practices involved in helping to gain and retain employment for these individuals. In this article the authors argue that the high levels of unemployment among people who experience mental illness, and the rising incidence of mental health and addictions issues in workplaces, offer the opportunity, as well as the mandate, for social work educators to provide professional education in the area of employment support and assistance.     

A new two-party bargaining mechanism

If resources and facilities from different partners need to be engaged for a large-scale project with a huge number of tasks, any of which is indivisible, decision on the number of tasks assigned to any collaborating partner often requires a certain amount of coordination and bargaining among these partners so that the ultimate task allocation can be accepted by any partner in a business union for the project. In the current global financial crisis, such cases may appear frequently. In this paper, we first investigate the behavior of such a discrete bargaining model often faced by service-based organizations. In particular, we address the general situation of two partners, where the finite Pareto efficient (profit allocation) set does not possess any convenient assumption for deriving a bargaining solution, namely a final profit allocation (corresponding to a task assignment) acceptable to both partners. We show that it is not appropriate for our discrete bargaining model to offer the union only one profit allocation. Modifying the original optimization problem used to derive the Nash Bargaining Solution (NBS), we develop a bargaining mechanism and define a related bargaining solution set to fulfil one type of needs on balance between profit-earning efficiency and profit-earning fairness. We then show that our mechanism can also suit both Nash’s original concave bargaining model and its continuous extension without the concavity of Pareto efficient frontier on profit allocation.     

论民族主义史学的兴起与缺失(下)--从全球比较史学的角度考察

民族主义史学是近现代史学的主要潮流。自 17世纪从西方兴起以后 ,随着西方殖民主义的扩张而走向全球 ,至今不衰。对于非西方地区的史家而言 ,民族主义史学为他们抵御西方军事和文化的侵略 ,从事民族国家的建设 ,起了重要的作用。尽管如此 ,民族主义本身是西方历史与文化的产物 ,并不完全适用于解释中国和印度等地区的历史。因此 ,需要从比较史学的角度 ,以西方、东亚、伊斯兰和印度等地民族主义史学的发展特点为例 ,分析民族主义史学的共性 ,及其在近年所面临的挑战 ,以展望全球史学在未来的发展走向     

Intergenerational Transmission and the Formation of Cultural Orientations in Adolescence and Young Adulthood

In this article we wanted to shed light on the intergenerational transmission and the formation of cultural orientations in adolescence. The intergenerational transmission was analyzed in different age groups in a longitudinal design (orientations of parents and their adolescent children were measured twice, with a time lapse of 3 years). Results clearly revealed that late adolescence is the “formative phase” for the establishment of cultural orientations and suggested that psychological processes such as internalization are guiding this formation. This internalization was found for all investigated orientations. In addition, as adolescents grew older, their susceptibility to parental orientations diminished, but, in contrast, parents did not become more susceptible to their children's orientations. No age effects in sociocultural influences were found. It was concluded that the investigated sociocultural influences should be seen as providing a structural context within which the formation of orientations in adolescence takes place.
