A theory has been proposed by Mulder that the tendency to take over superordinate power varies inversely with the power distance between ego and the target. As compared to the person who occupies the middle rank, an individual who is on the bottom rank has been shown to be less inclined to take over the top position. What will happen, however, if the latter individual had to act in terms of group instead of self? Will the induction of social categorization activate him to take over superordinate power? Three experimental conditions were set up by means of Mulder's cognitive representational method, using secondary school boys as subjects (N = 54). It was found that minimal social categorization did not enhance the tendency of the bottom member to take overpower. Enhancement effect was observed only in the condition of political categorization where the bottom member belonged to a majority group which had ingroup affinity to the source of power (p < .05). No such effect was found in the political categorization condition where the bottom member belonged to a minority group which did not have ingroup affinity to the source of power.

This study assessed the power of four theories in predicting individuals' perception of economic distributive justice: Self-interest Theory, Belief in a Just World, Attribution Theory, and Ideology. On the basis of a community survey of 487 adults, regression analyses showed that Self-interest Theory and Belief in a Just World provided moderate predictions of economic distributive justice perception; and Attribution Theory and Ideology yielded the strongest predictions. This finding has implications for future theoretical development.

Research on employee turnover has usually relied on employment status (quitters vs. stayers) to index the criterion variable (turnover), and on multiple regression (MR) to model the turnover process. In the present study, which was based on a national sample of nurses in New Zealand (n = 1249), we improved the criterion variable by combining employment status with a continuous measure, namely, job survival duration (length of employment starting from the time of survey). We then applied Cox's (1972) proportional hazards regression (PHR) analysis to the improved criterion, and compared the results with those obtained by applying MR on employment status. The comparisons favored PHR: (1) MR selected an extra predictor of quitting that turned out to be nonsignificant, and (2) the numbers of quitters estimated by PHR tended to be more accurate than those by MR.

ABSTRACTThis paper provides an introduction to a special issue focusing on diverse examples of policy practice in social inclusion and ageing across different regions of the world. These examples illustrate the multifaceted nature of the concept of social inclusion, and how it is applied in the context of global demographic ageing. The paper begins with an exploration of the history and development of the concept of social inclusion, as applied to ageing policy, and how the concept has emerged following its initial association with economic disadvantage. Now commonly defined as relating to social participation in key activities of the society in which people live, a social inclusionary approach highlights the risks of social exclusion and isolation faced by older people. Social inclusion thus incorporates core issues in ageing such as civil engagement, an ageing workforce, age-friendly communities, and civic involvement. There are some particular challenges to implementing social inclusion policies within the current environment, which are addressed within this special issue, and these include the impact of social and cultural change, particularly across some of the East Asian countries, and the impact of global financial crises on work and retirement.
