Social capital is the whole set of shared norms, values, attitudes, and beliefs that promote cooperation among individuals within the community and that has proved to be a key factor in explaining development processes. This article aims to provide an analytically reliable notion of social capital within the farming sector and a methodological tool for empirically measuring how social capital is accumulated at the farmer level. The theoretical framework proposed is based on the multidimensionality of the complex concept of social capital. Thus, to develop a comprehensive index for social capital, we identify three dimensions of the concept, structural, relational, and cognitive social capital, each one also comprising several subdimensions. This integrative approach permits creation of a composite indicator of the agricultural social capital accumulated at the farmer level, further identifying socioeconomic factors that influence its accumulation at that level. We empirically apply this methodological approach to farmers in Andalusia in southern Spain as a case study. This research provides an interesting starting point for informing policymakers about social capital and helping them implement the necessary programs to facilitate sustainable development in the agricultural sector.  相似文献

Doubly periodic non-homogeneous Poisson models for hurricane data   总被引:3,自引:1,他引:2  
Non-homogeneous Poisson processes with periodic claim intensity rate have been proposed as claim counts in risk theory. Here a doubly periodic Poisson model with short- and long-term trends is studied. Beta-type intensity functions are presented as illustrations. The likelihood function and the maximum likelihood estimates of the model parameters are derived.Doubly periodic Poisson models are appropriate when the seasonality does not repeat exactly the same short-term pattern every year, but has a peak intensity that varies over a longer period. This reflects periodic environments like those forming hurricanes, in alternating El Niño/La Niña years. An application of the model to the data set of Atlantic hurricanes affecting the United States (1899–2000) is discussed in detail.  相似文献

In this article we propose mixture of distributions belonging to the biparametric exponential family, considering joint modeling of the mean and variance (or dispersion) parameters. As special cases we consider mixtures of normal and gamma distributions. A novel Bayesian methodology, using Markov Chain Monte Carlo (MCMC) methods, is proposed to obtain the posterior summaries of interest. We include simulations and real data examples to illustrate de performance of the proposal.  相似文献

A non-negative AR(2) process with exponentially distributed white noise is investigated in the paper. It is assumed that the autoregressive parameters are random variables with a vague prior density. They can be esto,ated by their posterior expectations. Explicit formulas for these estimators are derived and their strong consistency is proved. An approximation to the estimators is proposed which is easier for calculation. The results are illustrated in a simulation study  相似文献

Chair yoga (CY), a mind-body therapy, is a safe nonpharmacological approach for managing osteoarthritis (OA) in older adults who cannot participate in standing exercise. However, there is no linguistically tailored CY program for those with limited English proficiency (LEP). This 2-arm randomized controlled trial compared the effects of a linguistically tailored yoga program (English and Spanish versions) on the outcomes of pain, physical function, and psychosocial factors compared to the effects of a linguistically tailored Health Education Program (HEP; English and Spanish versions). Participants with lower-extremity OA, recruited from 2 community sites, completed the Spanish (n = 40) or English (= 60) version of twice-weekly 45-min CY or HEP sessions for 8 weeks. Data were collected at baseline, 4 weeks, 8 weeks, and 1- and 3-month follow-ups. English and Spanish CY groups (but neither HEP language group) showed significant decreases in pain interference. Measures of OA symptoms, balance, depression, and social activities were not significantly different between English and Spanish versions of CY and English and Spanish versions of HEP. It was concluded that the Spanish and English versions of CY and HEP were equivalent. Linguistically tailored CY could be implemented in aging-serving communities for persons with LEP.  相似文献

This article addresses the following questions: (a) How common is child abuse among domestically violent families? (b) Are there specific patterns of child abuse among domestically violent families? (c) What may explain occurrences of child abuse in domestically violent families? (d) How might domestic violence affect treatment for child abuse? We review research on child abuse in the context of domestic violence. We discuss implications of this research for service-delivery programs for domestically violent families.  相似文献

The aim of this study was to determine the psychometric properties of a short version of the Fisher Divorce Adjustment Scale (FDAS–SF; Fisher, 1978) in the Chilean context. Participants were 260 individuals who were divorced or separated. The FDAS–SF included 22 of the original 100 items, and its factorial structure was evaluated using exploratory and confirmatory factor analysis. Instead of the 6 original subscales proposed by its author, the structure that showed the best fit to the data was composed of 5 subscales: self-worth, disentanglement from the ex-partner, anger, grief, and social trust. The social self-worth subscale was excluded. Reliability analyses revealed good internal consistency of the subscales and adequate convergent validity with depression, anxiety, stress, and life satisfaction. Given the psychometric properties of this short version, it can be concluded that the FDAS–SF can be used in the Chilean context to evaluate the adjustment to divorce and separation.  相似文献

After a survey on the work of prominent philosophers within the Western tradition, it can be noticed a tendency to view habits as automatic, unfree and unconscious behaviour. In this context, this article attempts to show that habits are actually much closer to the characteristics that are otherwise attributed to actions. That is, following the dialectical approach of Sartre, I develop arguments to support that habits are conscious actions carried out with a sense of identification towards the form of life that actions, in turn, project as a whole; in this way, each form of life requires a set of habits that the agent performs freely and rationally, understanding the latter as the dialectical procedure by which the act itself brings about a totalizing identity. This vision implies that habits are interrelated and codependent within a network of social behavior, so they cannot be discarded without discarding the form of life to which they belong. That is, a change of habit requires a change in the totality of which it is a part. But that change can only occur if social agents become aware that their habits are a product of their free acceptance and not of necessity. In the article, this latter is paradigmatically exemplified by neoliberal capitalism as a form of life.  相似文献

Objective

The occurrence of pediatric asthma has been associated with exposure to chronic stress. This study examined the relationship between maternal and community risk factors and asthma in a sample of maltreated children in foster care.

Method

Interviews were conducted with 365 maltreated children in foster care. Measures included youth/caregiver reports of asthma, an index of maternal risk based on data abstracted from child welfare records and community violence exposure.

Results

After controlling for demographic variables, maternal risk was associated with the presence of asthma (OR = 1.314, 95% CI = 1.09–1.58). Community violence exposure, however, was not related to the presence of asthma.

Conclusion

Maternal risk factors were significantly associated with the presence of asthma in a foster care population. Physicians who care for maltreated children in foster care should be particularly attuned to the presence of these additional risk factors that may place high-risk children at increased risk for chronic health problems.  相似文献
