Casework in Developing Nations

Although social casework began in the West as a child of the social reform movement, the two approaches have become widely separated during the intervening years. The developing nations are currently enacting mass development programs and the value of the Westernized casework method as taught in schools of social work and as an operational service delivery system must be evaluated in terms of national priorities. Literature on the subject is reviewed and some suggestions are made regarding the establishment of a holistic approach to social work in these countries.     

Aging in America: Limits to life span and elderly care options

Expanding longevity among the elderly and fertility decline are contributing to an aging US population. The number of persons 65 years or older is projected to double from about 32 million in 1990 to 66 million by 2030; the elderly proportion is expected to increase from 13 to 22 percent over the same period. Chronic illness and functional disability afflicts a significant proportion of older persons. An estimated 80–85 percent of people over age 65 have at least one chronic illness, and nearly one-half of older people report that chronic illness limits their activity to some degree. Altogether, about one-third of the population over 65 may need some kind of medical or social assistance. This paper discusses the three primary modes of care available to older persons: (1) the informal network of the family, (2) the more formal arrangements of home and community care, and (3) the institutionalized care of nursing homes. Of particular policy interest are the questions: Who provides the care? What type of care is available? Who receives the care? How much does each type of care cost? and Who pays? The current patterns and costs especially of long-term care provide a framework for planning future options. A discussion of research and policy recommendations concludes the paper.     

A new asymmetric class of bivariate copulas for modeling dependence

In this paper, we propose an asymmetric class of bivariate copulas. This class is obtained through limiting properties of the extended copula introduced by Bekrizadeh, et al. (2015 Bekrizadeh, H., Parham, G. A., Zadkarami, M. R. (2015). Extending some classes of copulas; Applications. Ph.D. Thesis, University of Shahid Chamran, Ahvaz. [Google Scholar]), and includes some of known copulas. Some general formulas for well-known association measures and concepts of dependence of the proposed model are obtained. This paper highlights the usefulness of this new bivariate copula for modeling the interested variables whose marginal distribution effect on joint distribution isn't identical. We apply some subfamilies of this new class to model a dataset of medical science to show the superiority of presented model in comparison with the known copulas. These results will be investigated using simulation.     

Social Capital in Association with Socioeconomic Variables in Iran

The objective of this study was to determine the various dimensions of social capital in Tehran and its association with socioeconomic variables. Two thousand, four hundred and eighty-four persons participated in the study through multi-stage stratified sampling in Tehran. The study questions were extracted from the World Bank integrated questionnaire. While respondents obtained over 50 % of the attainable scores in the ‘trust’, ‘cooperation’, ‘social cohesion’, and ‘political action’ dimensions, they obtained only 18.9 % of the attainable scores in the ‘networks’ dimension. The respondents in age groups older than 45 had higher trust scores than respondents in the 18–25 age group. Men had higher ‘network’ and ‘social cohesion’ scores than women (p ≤ 0.001). Respondents in the poorest wealth quintile had lower ‘networks’ and ‘social cohesion’ scores than the richest group and ‘political action’ scores higher than the richest group (p = 0.038). The lowest score in ‘Tehranians’ social capital was in the groups and networks dimension. Therefore designing effective interventions for such activities, particularly in women’s groups, is a priority.
