This paper discusses the social movement known in Italy as the movement of the centri sociali . The empirical material presented relies heavily on the centri sociali operating in Milan. Such material offers the opportunity to revisit issues related to social movement theories. In part one, a brief overview of these theories is sketched, and concepts suggested by both resource mobilisation theorists and new social movements theorists are presented. Attempts to unify the two approaches are also briefly reviewed. In part two, the origin of the centri sociali is traced. Some of the motives and practices inspiring the movement are described as a legacy, though re–elaborated and re–contextualised, of the particularly troubled, if compelling, Italian 1970s. The methodology used for the empirical work undertaken is then presented.
Finally, the discussion moves back to social movement theories, against which the movement of the centri sociali is analysed. Here, the utility of some aspects of both resource mobilisation and new social movement theories will be underlined, thus adding a modest, tentative, contribution to previous attempts to elaborate a synthesis between the two approaches.  相似文献

Most countries have designed programsto stimulate the birth and development of new firms.One of the most important issues in evaluating theimpact of public entrepreneurial policies is toanalyze their influence on the post-entry performanceof the new ventures. This paper examines how the mostimportant government program to encourageentrepreneurship in Italy (the Law 44 program) affectsseveral aspects of the early performance of new firms.A sample of new firms receiving government aid iscompared to a matched sample of new firms notreceiving public assistance, i.e., ``control' firms. The control firms were born in the same year, launchedtheir business in the same geographical area andoperate in the same industry classification. Resultsshow that the public program produces mixed effects.Government aid allows firms to have a higher level oftechnology. However, government funding gives rise toentrepreneurial start-ups, which are not fullyefficient. A discussion of these findings andsuggestions for future research are presented.  相似文献

Lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) represent one of the most common clinical complaints in adult men. Several drugs used for LUTS/BPO may strongly affect sexual function and bother. The aim of this systematic review and meta-analysis was to evaluate the impact of combination therapy with alpha-blockers (AB), 5-alpha reductase inhibitors (5-ARI) on the risk of erectile dysfunction(ED) and libido alterations (LA) from randomized clinical trial (RCT). Based on the inclusion and exclusion criteria, five RCTs involving 6131 patients were included in the analysis. According to the analysis, the overall prevalence of ED and LA were significantly greater in the combination treatment group than in the AB group (7.93% versus 4.66%; OR 1.81; p?p?=?0.003, respectively). The combination therapy increased the risk of ED compared to monotherapy with 5-ARI (7.93% versus 6.47%; OR 1.25; p?=?0.04) but not the risk of LA (3.51% versus 3.37; OR 1.03; p?=?0.84). In our systematic meta-analysis, we demonstrated that combination therapy with ABs and 5-ARIs was associated with significantly higher risk of ED and LA compared with single monotherapy. Combination therapy showed similar risk of LA compared with 5-ARI monotherapy.  相似文献

In this paper we present a non altruistic model of demand for children in the presence of uncertainty about children's survival. Children are seen as assets, as they provide help during old age. Theoretical predictions relating to the change in the mean and variance of the survival rate are derived. The empirical analysis is based on data from the Human Development of India (HDI) survey. Different models for count data variables, such as Poisson and hurdle models have been employed in the empirical analysis. The results highlight the importance of the uncertainty about children's survival in determining parental choices. This shows that realized or expected children's death is not the only link between fertility decision and children's mortality. The policy implications of such findings are briefly discussed.

Glass-cliff research shows that female leaders are preferentially selected in a crisis to signal change and not for their leadership qualifications. In parallel, the management literature urges for agentic “masculine” leadership to turn around organizations in crisis. We hypothesized that, regardless of their gender, agentic leaders should be preferred to communal leaders if leadership qualifications and actual change potential motivate leader selection. Three experimental studies demonstrated that agentic (vs. communal) candidates were perceived to match poorly-performing (vs. strongly-performing) companies. This effect was accounted for by perceptions of agentic candidates' higher suitability, higher task-orientation (versus person-orientation), and higher change potential. We discuss that women face ambiguity as to why they become leaders in crisis contexts: because they are perceived as signaling change, stereotypically linked to their gender, or for their perceived agentic qualities as leaders. In contrast, men become crisis leaders due to their perceived agentic change potential.  相似文献

The aim of this paper is to introduce a new approach for the synthesis and analysis of multidimensional poverty and well-being indicators. Our general perspective is inspired by the theoretical foundations of the capability approach and sustainable human development paradigm. The new synthesis of indicators aims at monitoring outcomes of units of interest. Its defining features include: full sensitiveness, continuity, flexibility in substitution between dimensions, and the straightforward interpretation of the results. All these properties are obtained through a transparent and accountable process that is fully open to public scrutiny and reason (as suggested by Amartya Sen). The main contribution of this approach is that the degree of substitutability between dimensions can be directly linked to the general level of well-being of a person, which addresses the so-called “inescapable arbitrariness” issue discussed by Anand and Sen (Concepts of human development and poverty: a multidimensional perspective. Human Development Papers. UNDP, New York, 1997). The new synthesis proposed opens up new possibilities for different types of applications, including monitoring and evaluating development programmes.  相似文献

What is the optimal allocation of prizes in an innovation race? Should the winner take all, or is it preferable that the original inventor shares the market with subsequent independent duplicators? Some recent papers in law and economics have argued that the latter, more permissive solution is socially preferable under mild conditions. We re‐examine that issue, arguing that a permissive regime may turn the innovation race into a waiting game, reducing the power of incentives, and may invite socially wasteful duplicative R&D expenditures. In a model that accounts for these effects, the winner‐take‐all system turns out to be preferable in a broad set of circumstances, especially in highly innovative industries.

We show that d'Aspremont and Gevers' (1977) characterization of utilitarianism can be strengthened by dropping the condition of transitivity of the social preference relation while slightly strengthening the Anonymity condition. The Anonymity condition we use is weaker, however, than the combination of transitivity and d'Aspremont and Gevers' Anonymity condition. Received: 24 January 1996/Accepted: 1 December 1997  相似文献

Using data for 9, 13 and 15-year-old students from three different datasets (PIRLS-2006, TIMSS-2007 and PISA-2009), we investigate whether the age at school entry affects children school performance at the fourth, eighth and tenth grade levels. Since student's age in a grade may be endogenous, we use an instrumental variable estimation strategy exploiting the exogenous variations in the month of birth coupled with the entry school cut-off date. We find that younger children score substantially lower than older peers at the fourth, the eighth and the tenth grade. The advantage of older students does not dissipate as they grow older. We do not find any significant effect of the relative age of a child with respect to the classmates’ age. Finally, we show that secondary school students are more likely to be tracked in more academic schools rather than in vocational schools if they are born in the early months of the year. From a policy point of view our results suggest that it might be useful to postpone the entry at school of children, or at least pupils should be prevented to anticipate the age of their entry at school. Tracking should also be delayed.  相似文献
