The relationships between the generations in Third World countries are changing as migration and industrialization erode traditional family responsibilities for supporting the elderly. It is no longer possible to assume that, as a matter of course, old people will be looked after by their families. Social change leads to an eroding of the support systems. The author finds growing evidence of this breakdown in Asia, particularly in Singapore, Hong Kong, and other highly industrialized centers. Singapore, for example, has reinstituted the compulsory study of filial piety in an attempt to push the younger generation into assuming its traditional responsibility toward the old. There has also been a significant decline in the status, prestige, and support given old people in Indonesia, although politicans insist that the family will always take care of its elderly. 2 reasons for this breakdown are 1) the impact of the mass media and 2) the increasing involvement of the younger generation in non-agricultural jobs which often involve a move to the city and away from dependence on a patriarch. Many Third World countries are in a twilight stage, between the traditionally strong structure of family support and government systems of social security.  相似文献

For the purpose of describing change in an economy's structure, and addressing issues of transformation, the notion of a time-dependent macroeconomic potential function is introduced. It penalizes deviations from equilibrium (entrepreneurial error) and induces moves toward equilibrium. Thus, from the concept of a potential function is derived the concept of short-term and long-term change forces. We focus here on the long-term structural changes of an economy as distinct from short-term cyclical variations, and we represent economic transformations as phase-transitions between monostable and ambiguous bistable states of the economy. One important feature of the potential function approach is that the parameter of the potential can be determined from empirical data. In particular, the parameters can be regressed for input variables. Hence, a relationship has been established between the structural change force and a set of input variables, some of which are controlled in part by either public or private sector agents. The method has been applied to West German and United States industry data for 1950–1980.  相似文献

Two surveys were conducted of volunteers working for recreation organizations in four New South Wales regions. The results highlight the dependence of these organizations on volunteers. Volunteers were found to be heavily engaged in instructing and organizing recreation activities. Few have any specific training for the role although further training is frequently considered desirable by respondents. Many respondents indicated that the government could assist voluntary work by providing— ? training at the local level, ? general financial assistance, and ? subsidies for equipment and facilities. Generally, responses indicate that the government should play a supportive rather than controlling role in recreation.  相似文献

ABSTRACT Despite increasing recognition of the importance of including the perspectives of children and young people in care in alternative care research, in practice this is not always a straightforward matter. This paper describes the recruitment of disruptive young people in care under the jurisdiction of the South Australian statutory authority to three studies on placement instability. Non‐response rates of 72.5% and 82% are reported. A large number of subjects were excluded because agency social workers did not cooperate with the project, and more subjects were excluded for reasons which suggest high levels of distress in this population. The dilemma of providing a voice to distressed subjects when distressed subjects are excluded from research is discussed, and the appointment of an independent representative for children in care to review research proposals and to negotiate research access to children is proposed.  相似文献

Do management tasks differ by field of practice?   总被引:1,自引:0,他引:1  
The authors examine the question: Do management tasks differ by field of practice? Many social work Master's programs are organized on the principle of specialization by field of practice for both micro- and macro-practice students. Secondary analysis of task data suggests that managers and supervisors with MSW degrees perform the same task regardless of the field of practice. The study suggests a need to examine assumptions of current MSW curriculum organization.  相似文献

Aumann's (1987) theorem shows that correlated equilibrium is an expression of Bayesian rationality. We extend this result to games with incomplete information.First, we rely on Harsanyi's (1967) model and represent the underlying multiperson decision problem as a fixed game with imperfect information. We survey four definitions of correlated equilibrium which have appeared in the literature. We show that these definitions are not equivalent to each other. We prove that one of them fits Aumann's framework; the agents normal form correlated equilibrium is an expression of Bayesian rationality in games with incomplete information.We also follow a universal Bayesian approach based on Mertens and Zamir's (1985) construction of the universal beliefs space. Hierarchies of beliefs over independent variables (states of nature) and dependent variables (actions) are then constructed simultaneously. We establish that the universal set of Bayesian solutions satisfies another extension of Aumann's theorem.We get the following corollary: once the types of the players are not fixed by the model, the various definitions of correlated equilibrium previously considered are equivalent.  相似文献
