Life expectancy and labor supply of the elderly

Most of the 20th century saw a progressive reduction in the labor market participation of older workers, but in the 1990s, there was a turning point in this trend across the developed world. Incentives to retire early have gradually been removed and, even, substituted by benefits for workers who remain active. This study shows that these reforms will find less and less opposition from workers as a consequence of the growth in their life expectancy, as long as it has a greater positive effect on the productivity of the elderly than on the value of leisure.     

The Future of Nuclear Power: Value Orientations and Risk Perception

Since the turn of the 21st century, there has been a revival of interest in nuclear power. Two decades ago, the expansion of nuclear power in the United States was halted by widespread public opposition as well as rising costs and less than projected increases in demand for electricity. Can the renewed enthusiasm for nuclear power overcome its history of public resistance that has persisted for decades? We propose that attitudes toward nuclear power are a function of perceived risk, and that both attitudes and risk perceptions are a function of values, beliefs, and trust in the institutions that influence nuclear policy. Applying structural equation models to data from a U.S. national survey, we find that increased trust in the nuclear governance institutions reduces perceived risk of nuclear power and together higher trust and lower risk perceptions predict positive attitudes toward nuclear power. Trust in environmental institutions and perceived risks from global environmental problems do not predict attitudes toward nuclear power. Values do predict attitudes: individuals with traditional values have greater support for, while those with altruistic values have greater opposition to, nuclear power. Nuclear attitudes do not vary by gender, age, education, income, or political orientation, though nonwhites are more supportive than whites. These findings are consistent with, and provide an explanation for, a long series of public opinion polls showing public ambivalence toward nuclear power that persists even in the face of renewed interest for nuclear power in policy circles.     

Paradoxes of late-modern autonomy imperatives: Reconciling individual claims and institutional demands in everyday practice

Governmentality studies and social theories agree that in contemporary societies the idea of autonomy is no longer simply an ideal or an individual aspiration but a social obligation. In an attempt to clarify the meaning of autonomy in this day and age, this paper asks how individuals perceive and negotiate the various dimensions of autonomy and how this affects the functioning of late-modern institutions. The empirical insights derived from a qualitative study provide a differentiated picture of how individuals pursue their claims to autonomy and comply with institutional demands for autonomy in everyday practice. By presenting seven types of late-modern “autonomy managers,” the analysis evinces a usurpation of autonomous agency that renders individuals the institutional editors of the contemporary contradictions, deficits, and tensions that occur in their everyday interactions. This comes at the price of notionally free but exhausted actors running short of all kinds of resources.     

What Impact Do Contextual Variables Have on the Changing Geography of Mortality in Italy?

Using data for 94 provinces, three periods (1971–1973, 1981–1983 and 1991–1993), and for men and women, we present an interesting picture of the geography of adult and elderly mortality by cause of death in Italy. This picture brings into focus the North/South gap that has yet again emerged, this time in gender differences in mortality. Particular attention is given to mortality from those causes that would appear to depend on the geographical context and that have a greater role to play in overall mortality differences. We then define which causes of death have changed the geographic pattern in the period considered. Lastly we study the relationship between mortality by cause and socio-economic, health care, environmental, cultural, and nutritional variables. This revised version was published online in July 2006 with corrections to the Cover Date.     

Union–intersection permutation solution for two-sample equivalence testing

One of the well-known problems with testing for sharp null hypotheses against two-sided alternatives is that, when sample sizes diverge, every consistent test rejects the null with a probability converging to one, even when it is true. This kind of problem emerges in practically all applications of traditional two-sided tests. The main purpose of the present paper is to overcome this very intriguing impasse by considering a general solution to the problem of testing for an equivalence null interval against a two one-sided alternative. Our goal is to go beyond the limitations of likelihood-based methods by working in a nonparametric permutation framework. This solution requires the nonparameteric Combination of dependent permutation tests, which is the methodological tool that achieves Roy’s Union–intersection principle. To obtain practical solutions, the related algorithm is presented. To appreciate its effectiveness for practical purposes, a simple example and some simulation results are also presented. In addition, for every pair of consistent partial test statistics it is proved that, if sample sizes diverge, when the effect lies in the open equivalence interval, the Rejection probability (RP) converges to zero. Analogously, if the effect lies outside that interval, the RP converges to one.     

Practices and rhetoric of migrants’ social exclusion in Italy: intermarriage,work and citizenship as devices for the production of social inequalities

The article aims to investigate the intersection of legislative dimensions, economic conditions and intimate life contributing to racialising and marginalising the poorest non-European migrants. First, this article focuses on the central role played by the private life in claiming citizenship rights and in building a sense of belonging within migratory contexts. As a result, mixed couples become a border zone through which the state disciplines immigrants according to their class, nationality and gender. On the other side, mixed couples and their intimate lives define resistance against the state’s biopolitical power to control people and become the space of intimate citizenship. Second, the article analyses the matrix for immigrants’ exclusion and differentiation embodied within the institutional and legislative system through immigration and citizenship laws. Therefore, the ‘coloniality power matrix’ becomes an active component of the naturalisation system of social differences at an institutional level.     

Cooperative learning: we can also do it without task structure

The present study focuses on the use of a cooperative methodology with university students during the last year of their degree programme. The task structure could be freely chosen, and there were no restraints on group decisions to deal with the classroom work. All the elements of cooperation were based on a reward structure. The results show that internal group cohesion can be achieved through an inter‐group competitive reward system and positive interdependence can be reached with an extreme cooperative reward structure, grounded on individual assessments of the students. The results also point to the importance of a reward structure, based on grades, when using a cooperative methodology in the university classroom.

Este estudio supone la utilización de una metodología cooperativa con alumnos universitarios en el último curso de la carrera. La estructura de tarea es siempre libre y no hay ninguna restricción a las decisiones del grupo para abordar el trabajo de aula. Todos los elementos de la cooperación se abordan desde la estructura de recompensa: la cohesión interna de los grupos se consigue mediante un sistema de recompensa competitiva intergrupal y la interdependencia positiva se logra mediante una estructura de recompensa cooperativa extrema, basada en las evaluaciones individuales de los alumnos. Los resultados demuestran la importancia que tiene una estructura de recompensa, basada en las calificaciones, para la aplicación de una metodología cooperativa al aula universitaria.     

A continuous rating method for preferential voting. The incomplete case

A method is given for quantitatively rating the social acceptance of different options which are the matter of a preferential vote. In contrast to a previous article, here the individual votes are allowed to be incomplete, that is, they need not express a comparison between every pair of options. This includes the case where each voter gives an ordered list restricted to a subset of most preferred options. In this connection, the proposed method (except for one of the given variants) carefully distinguishes a lack of information about a given pair of options from a proper tie between them. As in the special case of complete individual votes, the proposed generalization is proved to have certain desirable properties, which include:  the continuity of the rates with respect to the data,  a decomposition property that characterizes certain situations opposite to a tie,  the Condorcet–Smith principle,  and clone consistency.     

Fornicatie and Hoerendom or the Long Shadow of the Portuguese: Connected Histories,Languages and Gender in the Indian Ocean and Beyond

Abstract

Processes of creolisation, some of which went by the name of ‘miscegenation’ in older colonial studies, have a much broader area of distribution than the colonial and postcolonial spaces wherein they are traditionally studied. In fact, they originate in a very large area of the Indian Ocean and the Mediterranean Sea, and are ultimately not colonial in origin. Moreover, these processes involved social technologies that were gendered and deeply affected knowledge networks and movement of people and goods in the Indian Ocean and beyond. Processes of creolisation in the Americas can also be traced back to these ancient Indian Ocean patterns. Those processes have been somewhat overlooked by traditional nation-centred historiographies. They have, however, noticeably inflected colonial and postcolonial imaginaries through a variety of local languages, such as, for instance, from west to east: Brazilian Portuguese, Afrikaans, Netherlands Indies Dutch or Malay-Indonesian. They also find expression in various kinds of narratives, including historiographical works. Only a connected history, linked to a translinguistic approach, will be able to retrieve more fully the complexities and nuances of those ancient networks of people and knowledge transfer.
