Urban Poverty,Ethnicity, and Personality Development

There are multiple factors which contribute to the development of the individual’s personality. Many of these factors have been amply discussed in traditional theories of personality Jonnation. An area that has been neglected in these discussions has been the role that poverty and ethnic and cultural factors may have in this regard. This paper offers a discussion of these issues with special emphasis on cultural, ethnic, and socioeconomic factors which tend to characterize the lives of Latino and Black individuals. Recommendations are made for a re-evaluation of the traditional theories of personality when applied to poor and minority individuals.     

Small mammal assemblages in fragmented shrublands of urban areas of Central Chile

Mediterranean-type ecosystems are one of the most affected environments by habitat loss and fragmentation due to urban development, however only few studies have evaluated the effects of urbanization on the biodiversity of remnant fragments in these ecosystems. This study aims to evaluate the effects of urban development over small mammal assemblages inhabiting isolated forest fragments of an urban area of Chilean Mediterranean zone. We compared abundance and richness of small mammal assemblages of six remnant fragments within an urban matrix, and six fragments similar in area and habitat characteristics with those of urban area, but surrounded by a rural matrix. We found that small mammal assemblages differ considerably among fragments types (urban vs rural), with lack of endemic species from urban fragments and with high proportion of introduced rodents in urban fragments. Furthermore abundance of small mammals was higher in rural than in urban fragments. In urban areas small mammal abundance and richness were not correlated with any of the explanatory variables assessed (woody cover, flora heterogeneity, fragment area, perimeter/area ratio). However in rural fragments small mammal richness was negatively correlated with flora heterogeneity and the abundance of small mammals was positively correlated with perimeter/area ratio. These results reveal important differences within the effects of fragmentation over small mammal assemblages among the two types of fragments assessed. Our findings suggest that in forest fragments isolated by urbanization, larger areas with good quality habitats are not sufficient to maintain native small mammal population.     

Growing Parental Economic Power in Parent–Adult Child Households: Coresidence and Financial Dependency in the United States, 1960–2010

Research on coresidence between parents and their adult children in the United States has challenged the myth that elders are the primary beneficiaries, instead showing that intergenerationally extended households generally benefit the younger generation more than their parents. Nevertheless, the economic fortunes of those at the older and younger ends of the adult life course have shifted in the second half of the twentieth century, with increasing financial well-being among older adults and greater financial strain among younger adults. This article uses U.S. census and American Community Survey (ACS) data to examine the extent to which changes in generational financial well-being over the late twentieth and early twenty-first centuries have been reflected in the likelihood of coresidence and financial dependency in parent–adult child U.S. households between 1960 and 2010. We find that younger adults have become more financially dependent on their parents and that while older adults have become more financially independent of their adult children, they nevertheless coreside with their needy adult children. We also find that the effect of economic considerations in decisions about coresidence became increasingly salient for younger adults, but decreasingly so for older adults.     

Gender wage discrimination at quantiles

The literature provides several scalar measures of gender wage discrimination that cannot identify whether discrimination is greater among high earners or among low earners. Furthermore, two populations may exhibit the same value of the scalar measure while discrimination could be very differently distributed. We extend Oaxacas scalar measure to any quantile of the distribution of wages. Our measure allows comparisons within a population and inter-population. Using the Spanish Survey of Wage Structure we find that gender wage discrimination increases with the quantile index but as a fraction of the gender wage gap reaches a maximum at the ninth percentile.All Correspondence to Javier Gardeazabal.

Intermediate inequality and welfare

We introduce a new centrist or intermediate inequality concept, between the usual relative and absolute notions, which is shown to be a variant of the α-ray invariant inequality measures in Pfingsten and Seidl (1997). We say that distributions x and y have the same (x, π)-inequality if the total income difference between them is allocated among the individuals as follows: 100π% preserving income shares in x, and 100(1−π)% in equal absolute amounts. This notion can be made as operational as current standard methods in Shorrocks (1983). Received: 13 May 1998/Accepted: 25 January 1999     

Determining socio-demographic predictors of treatment dropout: results in a therapeutic community

This article presents a study of a number of socio-demographic factors that predict treatment dropout from a residential substance use disorder programme in Spain ( Proyecto Hombre Therapeutic Community). A sample of 430 patients (173 who completed treatment and 257 who dropped out of treatment) was assessed at entry to the therapeutic community programme in order to collect information on socio-demographic characteristics of the participants. According to the results obtained, factors that predicted treatment dropout included younger age, male gender and previous treatment history in the Proyecto Hombre therapeutic community. Patients with these characteristics were at significantly greater risk of dropping out of treatment. The implications of these results for further research and clinical practice are commented upon.     

Bayesian design in queues: An application to aeronautic maintenance

We exploit Bayesian criteria for designing M/M/c//r$M/M/c//r$ queueing systems with spares. For illustration of our approach we use a real problem from aeronautic maintenance, where the numbers of repair crews and spare planes must be sufficiently large to meet the necessary operational capacity. Bayesian guarantees for this to happen can be given using predictive or posterior distributions.     

In search of optimal management of the purchasing–marketing interface for new product development

Abstract

Growing dependence on suppliers for production and innovation, together with increasing consumer demands, has prompted recent discussions of the importance of purchasing–marketing functional integration. However, empirical studies are needed to understand how to manage this interface within a new product development (NPD) context. This study, grounded in information processing theory, proposes a new model to classify integrating mechanisms as either information-sharing forums or optimizers. This model further postulates the greater capacity of optimizer mechanisms for improving NPD commercial and financial performance, as well as speed. The empirical results, obtained from a sample of 141 firms, show that forums only improve NPD speed, whereas optimizer mechanisms evoke better commercial and financial performance. This study therefore highlights the potential of different integrating mechanisms and contributes to the on-going debate about the very concept of functional integration itself.     

Educational potential of e-social work: social work training in Spain

ABSTRACT

Information and communication technologies (ICTs) have enhanced peer communication and contributed to social change and, as such, have become an essential tool in the initial training and professional development of future social work practitioners. In the new millennium, it is particularly important to provide the foundations for delivering appropriate interventions in the fields of social education, social services, healthcare and development cooperation. To face these new challenges, training programmes in the framework of the European Higher Education Area should facilitate the acquisition of skills and competencies through curricula based on ongoing assessment which promote creativity and educational innovation. Through a systematic and comprehensive review of the scientific literature, this article examines the educational potential of e-social work in Spain and the training needs of social workers from an interdisciplinary approach. A critical debate is presented throughout the paper to encourage reflection among professionals. The study highlights the importance of the acquisition of digital skills through the development of educational intervention programmes using the latest technological media and resources with a view to serving citizens in these new spaces of interaction.
