Recently, we developed a GIS-Integrated Integral Risk Index (IRI) to assess human health risks in areas with presence of environmental pollutants. Contaminants were previously ranked by applying a self-organizing map (SOM) to their characteristics of persistence, bioaccumulation, and toxicity in order to obtain the Hazard Index (HI). In the present study, the original IRI was substantially improved by allowing the entrance of probabilistic data. A neuroprobabilistic HI was developed by combining SOM and Monte Carlo analysis. In general terms, the deterministic and probabilistic HIs followed a similar pattern: polychlorinated biphenyls (PCBs) and light polycyclic aromatic hydrocarbons (PAHs) were the pollutants showing the highest and lowest values of HI, respectively. However, the bioaccumulation value of heavy metals notably increased after considering a probability density function to explain the bioaccumulation factor. To check its applicability, a case study was investigated. The probabilistic integral risk was calculated in the chemical/petrochemical industrial area of Tarragona (Catalonia, Spain), where an environmental program has been carried out since 2002. The risk change between 2002 and 2005 was evaluated on the basis of probabilistic data of the levels of various pollutants in soils. The results indicated that the risk of the chemicals under study did not follow a homogeneous tendency. However, the current levels of pollution do not mean a relevant source of health risks for the local population. Moreover, the neuroprobabilistic HI seems to be an adequate tool to be taken into account in risk assessment processes. 相似文献

The Spanish Civil War (1936—1939) interrupted the evolution and development of social pedagogy, which in Spain had reached similar levels as in other European countries. This was followed by a period when Spain was isolated from developments in social welfare and the changes that go along with the economic and social transformations of cities and give rise to community action, self-help and popular education programmes. The reinstatement of democracy and of new City Councils that are genuinely devoted to solve the problems of the population are the starting point for new social services, that is for social work and social pedagogy. Initially it was practical work that gave an answer to emerging demand, followed by theoretical analysis and efforts of conceptualisation. The professionals and later the universities lead the debate on methodology. The interest and involvement of the universities increased as the Diploma in Social Education was introduced as a new university degree. 相似文献

The development of social policy related to religion has received increasing focus in recent years, yet psychology continues to play a relatively minor role in this important domain. In the current article, religion's positive and negative influences as a meaning system on individual, community, and societal well-being are delineated. The challenges facing psychology in contributing to public policy development in the religious arena are examined, challenges that stem from profound differences in the meaning systems of religion, government, and psychology. These challenges notwithstanding, a number of different pathways in the domains of applied research, community practice, and policy development are delineated through which psychology can help to maximize positive, and minimize negative, outcomes in the religion and social policy arena. 相似文献

Current findings are still inconclusive with regard to the role played by the characteristics of social networks in INVs’ early geographical scope. This study analyses how entrepreneurial-oriented networks affect new ventures’ early geographical scope through critical capabilities. We have adopted a behavioural perspective to investigate the effect of social networks both on international new ventures’ geographical scope and on their critical capabilities such as absorptive and adaptive capabilities. Results from a sample of 183 Spanish international ventures confirm the importance of entrepreneurial orientation as a network characteristic for early geographical scope. Additionally, the positive effect of adaptive capability on new ventures’ early geographical dispersion has been confirmed but not so in the case of absorptive capabilities. Our results suggest that future research must be careful to assume international new ventures’ absorptive capability as a prerequisite to their cross-border expansion. 相似文献

We propose a new and simple adaptive procedure for playing a game: ‘regret‐matching.’ In this procedure, players may depart from their current play with probabilities that are proportional to measures of regret for not having used other strategies in the past. It is shown that our adaptive procedure guarantees that, with probability one, the empirical distributions of play converge to the set of correlated equilibria of the game. 相似文献

ABSTRACTeLearning has become an academic tool used to provide access to education for multiple segments of the population, which otherwise would have little to no access to it. While other academic disciplines integrated it into their curricula early in the digital revolution, in many countries, social work education is just beginning to address the opportunities and challenges web-based learning may bring to these programmes [Blackmon, 2013. Social work and online education with all deliberate speed. Journal of Evidence-Based Social Work, 10(5), 509–521. doi:10.1080/15433714.2012.663672; Phelan, 2015. The use of eLearning in social work education. Social Work, 60(3), 257–264. doi:10.1093/sw/swv010]. This international collaborative research study seeks to better understand the challenges and opportunities faced by social work educators teaching at universities who are already using some form of eLearning in the United States and in Spain. A quantitative, non-experimental research design was employed. Results show that there are similarities as well as differences in the ways the two subsamples perceive the challenges and opportunities of eLearning. Findings reveal that there are some significant differences between the way the two subsample respondents perceived challenges and opportunities to eLearning. Recommendations for online social work educators and administrators are provided regarding overcoming challenges and capitalizing on opportunities applicable to the US, Spain, and the larger European and global contexts. Recommendations for further research and practice are also included. 相似文献
