Abstract

As theologian Henri Nouwen has pointed out, the opposite of love is not hate; it is fear. Nowhere is the fear which strips us of our capacity to behave rationally better evidenced than in relation to AIDS. Only as we allow ourselves to be moved from what Nouwen calls the house of fear into the house of love will responsible answers begin to be formulated to the emerging moral questions presented by AIDS. The questions are threefold. To those potentially at risk for AIDS or actually infected with it, it raises questions about honesty and love in sexual relations. For caregivers, it raises questions about the nature of our professional obligations. And for society at large, it raises questions about confidentiality and scapegoating. It is the author's contention that an experience of the divine love—unconditional, unmerited, unbounded—is alone sufficient to move us from fear, and its responses to AIDS, to a more loving (and courageous) stance. Only thus will we begin—whether as victims of AIDS, as caregivers, or as members of society at large—to exercise moral responsibility with respect to this dread disease.  相似文献

Since the mid-1980s, street gangs known as maras have emerged as a new social entity in Central America. In Honduras, these informal organizations are repeatedly represented in various forms of media as an aberration that is clearly separate from populace and state. Such representations render mareros as entities that possess a radically alien ontology, which is the sole locality of intervention of anti-mara programs. This article analyzes popular media and ethnographic observations to demonstrate that a) rather than being an alien ontology, marero subjectivities are co-constituted through nation and class-forming practices and b) despite such representations, Hondurans of various walks of life routinely subvert attempts to create a tripartite body politic of state-populace-marero. Continued emphasis on the marero as the sole site of intervention and rehabilitation deals with the mara issue at a symptomatic level and fails to address the quotidian processes that give form to this phenomenon.  相似文献

This article explains the success of All Puerto Rico with Vieques (TPRCV) in coordinating a broad-based coalition in support of the movement to remove the US Navy from Vieques. Considering the literatures on organizations, strategic fields and social movements, the analysis looks at how environmental conditions and the attributes of the leadership become relevant in the formation and sustainability of coalition work. The article argues that under the conditions of a vibrant political activist sector and a dynamic political field, TPRCV used accumulated social skills to take advantage of network intersection and frame adaptation. Though environmental dynamics may produce favorable conditions for coalition building, these will be limited to the capacity of the social actors to identify them, assimilate their potential and translate them into opportunities.  相似文献

This paper investigates the relationships among corporate ownership, the level of board compensation, and firms’ future performance within Italian listed companies. Board compensation could be related to corporate ownership characteristics, like the type of controlling shareholder, ownership concentration, the separation between cash flow and voting rights, and the presence of shareholders’ agreements. The evidence of high levels of board compensation associated with certain governance characteristics could signal, in a principal-agent framework, rent extraction by entrenched managers or by controlling shareholders versus minority shareholders; high board compensation, however, could be related to the need to hire directors with higher professional standing and also to the desire to create a network with other companies through the enlargement of the board, according to a social network view. In this paper we disentangle this issue showing the relationship between excess board compensation and future performance: examining firms listed on the Milan Stock Exchange over the period 1995–2002, we show that board compensation is linked to many governance characteristics, but excess compensation is never positively related to future performance. For founder family firms, in particular, high board compensation is associated with (a) smaller board size; (b) higher proportion of family members on the board; (c) lower future performance. The whole evidence therefore doesn’t support the hypothesis suggested by the social network view, but is consistent with a rent extraction hypothesis. These results could add new empirical evidence to the recent debate on the need for global remuneration reform. According to our results, some control mechanism and an increase in transparency of executive compensation schemes could be appropriate.  相似文献

In many European countries requirements for retirement have been tightened, causing an increase in work participation of older workers, in spite their potentially poorer health may limit their work ability. This study aimed at assessing the diffusion of health problems and exposure to unfavorable working conditions among ageing workers in two Italian surveys, as well as comparing them with those observed in the same surveys conducted before the 2011 Italian pension reform tightening the normal retirement age. The 2013 National Health Survey (NHS) and Labour Force Survey (LFS) were employed to assess the prevalence of poor perceived health, health conditions and functional limitations, and of exposure to physical, psychosocial and organization factors at work, among 60–64 years workers. Poisson regression models were used to estimate Prevalence Ratios of health outcomes and unfavorable working conditions in the two surveys, compared to data from the 2005 (NHS) and 2007 (LFS) corresponding surveys, respectively. Among both men and women, approximately one quarter had at least one physical disorder or functional limitations and 15% poor mental health. Exposure to different ergonomic factors (15–30%) and working during unsocial hours (19%) were particularly diffused. A significant increase in the prevalence of functional limitations and of working at night or during unsocial hours was found in 2013, compared to corresponding data from 2005 and 2007, respectively. Our results indicate that exposure to ergonomic and organizational hazards should be reduced among ageing workers, to avoid decreased work ability, health damage or early exit from the labour market.

In this paper four regression estimators are considered for a finite population total based on interpenetrating subsamples, two of which are with jackknifing and the other two are without jackknifing. Both theoretical and empirical comparisons of the four proposed estimators are done with respect to bias, variance and mean square error.  相似文献

ABSTRACT

The procedure for online control by attribute consists of inspecting a single item at every m items produced (m ≥ 2). On each inspection, it is determined whether the fraction of the produced conforming items decreased. If the inspected item is classified as non conforming, the productive process is adjusted so that the conforming fraction returns to its original status. A generalization observed in the literature is to consider inspection errors and vary the inspection interval. This study presents an extension of this model by considering that the inspected item can be rated independently r (r ≥ 1) times. The process is adjusted every time the number of conforming classifications is less than a, 1 ≤ a ≤ r. This method uses the properties of an ergodic Markov chain to obtain the expression for the average cost of this control system. The genetic algorithm methodology is used to search for the optimal parameters that minimize the expected cost. The procedure is illustrated by a numerical example.  相似文献

In this work, a generalization of the Goodman Association Model to the case of q, q > 2, categorical variables which is based on the idea of marginal modelling discussed by Gloneck–McCullagh is introduced; the difference between the proposed generalization and two models, previously introduced by Becker and Colombi, is discussed. The Becker generalization is not a marginal model because it does not imply Logit Models for the marginal probabilities, and because it is based on the conditional approach of modelling the association. The Colombi model is only partially a marginal model because it uses simple logit models for the univariate marginal probabilities but is based on the conditional approach of modelling the association. It is also shown that the maximum likelihood estimation of the parameters of the new model is feasible and, to compute the maximum likelihood estimates, an algorithm is proposed, which is a numerically convenient compromise between the constrained optimization approach of Lang and the straightforward use of the Fisher Scoring Algorithm suggested by Glonek–McCullagh.Finally, the proposed model is used to analyze a data set concerning work accidents which occurred to workers at some Italian firms during the years 1994–1996.  相似文献

Using a representative sample of currently legal third-country immigrants in Italy, obtained from the Social Condition and Integration of Foreign Citizens survey, this article examines the long-term labour market consequences of previous undocumented spells. First, formerly undocumented immigrants are identified using retrospective information on respondents' legal status. Second, immigrants are classified according to the duration of irregular spells before the achievement of the first residence permit. Third, current labour market outcomes are investigated to account for the endogeneity underlying the previous undocumented history. Results show that even though formerly undocumented immigrants are more likely to participate in the labour market, they are more likely to be employed in underqualified occupations than continuously legal immigrants. The duration of the irregular experience affects occupational qualification negatively, among both men and women. The lack of legal entry channels and policies to plan and regulate migration to Italy may reinforce labour market segmentation, exposing migrants to long-term occupational downgrade.  相似文献
