Radical and autonomous urban movements like the European squatters' movement tend to resist integration into the institutions of the state, although particular legal and political conditions in each country or city may significantly alter this tendency. In this article, I examine the controversial issue of ‘institutionalization’ among squatters, focusing on the few cases of legalized squats (social centres) in the city of Madrid. Negotiations with the state authorities and processes of legalization are the major forms of institutionalization involving squatters. However, an anomalous kind of institutionalization also emerges once squats, whether legalized or not, become consolidated and socially accepted. For squatting to have a successful impact, then, depends on both the type of autonomy achieved by squatters and the different outcomes of the processes of institutionalization. The case of Madrid provides empirical evidence that: (1) negotiations with state authorities were very frequent among squatters, but most were defensive; (2) the few cases of legalization were due to specific conditions such as the urban centrality of the squats, single‐issue identities, social network solidarity, favourable media coverage, formal organizations working as facilitators and the squatters' leadership of the process. Furthermore, legalized squats in Madrid preserved a high degree of autonomy, self‐management and ties to other radical social movements. In conclusion, both the legalized squats and the squatters' movement in Madrid as a whole, avoided ‘terminal institutionalization’ and, instead, gave shape to a ‘flexible’ one.  相似文献

A partir de datos del Panel de Hogares de la Unión Europea (PHOGUE) sobre Austria, España, Grecia, Irlanda, Italia y Portugal de 1995–2001 se examina la influencia de la discapacidad en el absentismo laboral utilizando tres variables: el estado de salud autoevaluado, el número de visitas al médico y el número de noches de ingreso en hospital. Según los resultados, el absentismo entre los trabajadores con discapacidad es mayor. La gravedad de la discapacidad también tiene influencia. El efecto total de la discapacidad en el absentismo representa un incremento marginal de entre 6 y 26 días de ausencia al año (dependiendo del país).  相似文献

Logistic activity can be thought of as a socio-technical process whereby a social network of individuals orchestrates a series of technical activities using supporting systems such as transportation and communications. To understand the functioning of the entire system requires proper consideration of all its components. We identify seven key components: the objectives being pursued, the origin of the commodity flows to be transported, knowledge of demand, the decision-making structure, periodicity and volume of logistic activities, and the state of the social networks and supporting systems. Based on our analysis of the differences between commercial and humanitarian logistics, we pinpoint research gaps that need to be filled to enhance both the efficiency of humanitarian logistics and the realism of the mathematical models designed to support it.We argue that humanitarian logistics is too broad a field to fit neatly into a single definition of operational conditions. At one end of the spectrum we find humanitarian logistic efforts of the kind conducted in long-term disaster recovery and humanitarian assistance, where operational efficiency – akin to commercial logistics – is a prime consideration. At the other, post-disaster humanitarian logistic operations involved in disaster response and short-term recovery activities represent a vastly different operational environment, often in chaotic settings where urgent needs, life-or-death decisions and scarce resources are the norm. The huge contrast between these operational environments requires that they be treated separately.  相似文献

Employment fluctuations are examined, at different levels of aggregation, in a model with firm-specific hiring decisions due to search frictions and sticky pricing. The results indicate that firm-level employment dispersion rises with higher price stickiness and higher demand elasticity, whereas it falls with more convexity of search costs and with a higher labor supply elasticity. Industry-level employment is more volatile and less procyclical than aggregate employment, and a larger industry size reduces volatility and raises co-movement with output. The calibrated model is able to match the volatility, autocorrelation and cyclical correlation of US industry-level employment when incorporating firm-specific technology shocks.  相似文献

For trade unions, the central problematic of globalization is the growing disparity between the mobility of capital and labour. The ability of capital to operate on a trans-national basis is widely perceived to have precipitated a process of cost cutting as international companies seek to cut workers' remuneration and other conditions of employment. However, systematic empirical evidence on the impact of globalization on human resource management is hard to find, as is any assessment of the differential impact of globalization on different occupational groups or the response of trade unions to any deterioration in their members' terms and conditions of employment. Focusing on the international civil aviation industry, we examine the effects of globalization on human resource management and the national and international strategies developed by organized labour in response. Although the evidence suggests that there is indeed a concerted effort by major airlines to cut costs, trade unions have been able to retard the pace of change and effectively defend the interests of some occupational groups. Moreover, the future course of globalization will be contested through new international strategies and repertoires of collective action developed by the trade union movement.  相似文献

From 1980 to 1990 Portugal experienced a generalized liberalization of economic activity, due in large part to its 1986 integration in the European Union. This paper studies the changes in the Portuguese distribution of household income and expenditure during this period, using micro-data on household budgets and applying recent developments in statistical inference for Lorenz curves. We find a significant increase in six measures of welfare and an unambiguous decrease in the inequality of the respective distributions. Different explanations for the findings of decreased inequality are discussed.  相似文献

The aim of this paper is to analyse the construct involvement. Specifically, the present work extends the sphere of study of the construct involvement at brand level, applying it to Denominations of Origin (D.O.s). Hence, after an overview of the concept, it suggests a cognitive approach to the measurement of involvement. It proposes as indicators the number of values associated with this designation, the centrality of these values and the intensity of the association. In this delimitation of the concept, a model is presented that is set within the framework of an analysis of the decision-making process adopted by consumers when purchasing wine. This postulates that temporary involvement with a D.O. has explanatory power, as does the direct effect of the regular outcomes of a permanent involvement with such a designation on the process in question. In addition, a correlation is proposed between the state of temporary involvement with a D.O. and the continuing consequences of a permanent involvement with this designation.  相似文献

In this paper, a sufficient condition for non-negative random variables to be ordered in the Generalized Lorenz sense is presented. This condition does not involve inverse distribution functions. Applications of this result to several income distribution models are given. Journal of Economic Literature Classification Numbers: D36, D69.  相似文献
