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

We argue that the long‐term influence of actors in fields of cultural production depends on the opportunities for resource mobilization offered by external conditions combined with intense interaction among actors. Using a unique data set of 1,143 architects active between 1890 and 1940, at a time of large‐scale socioeconomic transformations and political disruption, we find by multiple regression analysis that exposure to industrialization and political upheaval, and halo effects in an architect's network of collaborators predict greater ultimate impact, while urbanization and professional affiliations do not. Theory of social movements and theory of cultural production thus have important implications for each other.  相似文献

Objective: In this study we aimed to investigate the association between dietary phytoestrogen consumption and prostate cancer in a sample of southern Italian individuals.

Methods: A population-based case-control study on the association between prostate cancer and dietary factors was conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy (Registration number: 41/2015). A total of 118 histopathological-verified prostate cancer (PCa) cases and a total of 222 controls were collected. Dietary data was collected by using two food frequency questionnaires.

Results: Patients with PCa consumed significantly higher levels of phytoestrogens. Multivariate logistic regression showed that lignans (Q[quartile]4 vs. Q1, OR [odds ratio]?=?4.72; p?p?p?p?p?p?p?Conclusion: We found of an inverse association between dietary isoflavone intake and PCa, while a positive association was found with lignans intake.  相似文献

The three-partition problem is one of the most famous strongly NP-complete combinatorial problems. We introduce properties which, in many cases, can allow either a quick solution of an instance or a reduction of its size. The average effectiveness of the properties proposed is tested through computational experiments.  相似文献

The global controversy regarding the use of genetically modified (GM) crops has proved to be a challenge for "science-based" risk assessments. Although risk analysis incorporates societal perspectives in decision making over these crops, it is largely predicated on contrasts between "expert" and "lay" perspectives. The overall objective of this study is to explore the role for farmers' knowledge, and their decade-long experience with herbicide-tolerant (HT) canola, in the risk analysis of GM crops. From 2002 to 2003, data were collected using interviews ( n = 15) and mail surveys ( n = 370) with farmers from Manitoba and across Canada. The main benefits associated with HT canola were management oriented and included easier weed control, herbicide rotation, and better weed control, whereas the main risks were more diverse and included market harm, technology use agreements (TUAs), and increased seed costs. Benefits and risks were inversely related, and the salient factor influencing risk was farmer experiences with HT canola volunteers, followed by small farm size and duration using HT canola. These HT volunteers were reported by 38% of farmers, from both internal (e.g., seedbank, farm machinery, etc.) and external (e.g., wind, seed contamination, etc.) sources, and were found to persist over time. Farmer knowledge is a reliable and rich source of information regarding the efficacy of HT crops, demonstrating that individual experiences are important to risk perception. The socioeconomic nature of most risks combined with the continuing "farm income crisis" in North America demonstrates the need for a more holistic and inclusive approach to risk assessment associated with HT crops and, indeed, with all new agricultural technology.  相似文献

Heath and Tversky (1991, Journal of Risk and Uncertainty 4:5–28) posed that reaction to ambiguity is driven by perceived competence. Competence effects may be inconsistent with ambiguity aversion if betting on own judgement is preferred to betting on a chance event, because judgemental probabilities are more ambiguous than chance events. This laboratory experiment analyses whether ambiguity affects prices and volumes in a double auction market, and contrasts ambiguity aversion to competence effects. In order to test for the presence of competence effects, in the experiment uncertainty is tied to the realisation of events about which the decision maker is more or less knowledgeable. Two experiments are presented: in the first, knowledge is exogenous, whereas in the second the knowledge judgement is endogenous. Market prices provide evidence in favour of the competence hypothesis only when competence is self-assessed. Comparable volumes are observed in both experiments.   相似文献

ABSTRACT

Circuit parties (CP) are extended celebrations, lasting from a day to a week, primarily attended by gay and bisexual men in their thirties and forties. The increasing popularity of circuit parties may play a significant role in the epidemiology of HIV and other sexually transmitted diseases. We performed a systematic literature search in MEDLINE, without any temporal limit, using the term “circuit party”. Only articles reporting cross-sectional studies were analyzed. Ten articles, published in the period from 2001 to 2015 were included in our systematic review and reported data on samples ranging from 173 to 13,883 gay/bisexual men. The HIV prevalence among men who attended the CPs was very high, ranging from 6% to 40.8%. Sexual risk behaviors (e.g. unsafe sex or multiple partners) and drug use were particularly frequent. It wo'uld be useful to promote efficient strategies with the cooperation of party planners, catching the participants before nightlife activities in order to prevent HIV transmission and the use of recreational drugs.  相似文献

In this contribution we show that the dualistic nature of the Italian economy has been, and still is, crucial for the design of short- and long-run macroeconomic policies, concerning unemployment, income growth and public finance.We establish the seriousness of the dualistic process of Italian regional development using several approaches. We then considered the regional nature of the Italian unemployment and show that it has profound implications for short- and long-run policies. In particular, we find that an aggregate price–unemployment relationship must be rejected. Different values of equilibrium unemployment rates for the main macro-regions of Italy are found and short-run policy implications discussed. We then consider how this heterogeneity relates to the design of growth-promoting policies.Lastly, we present evidence in favor of the importance of the missing growth of the Italian southern regions for the evolution of the Italian public finance.  相似文献
