Family Context and Spanish‐Language Use: A Study of Latino Children in the United States*

Objective. This article seeks to explain why Latino children maintain some knowledge of their native language even though past research has consistently supported the view that non‐English‐language use rarely lasts past the third generation. I argue that family context, in addition to assimilation characteristics, plays an important role in determining their language situation. Method. I use both logistic regression and tobit regression, as well as data from the 1988 National Education Longitudinal Study, to examine the use and proficiency of Spanish among Latino children. Results. The results demonstrate that language and family context strongly influence Spanish usage and proficiency for Latino children, regardless of generational status. Conclusions. These findings reveal a relationship between assimilation, family, and language that can have important implications for the future academic and economic success of Latino children.     

The Choice Revolution: Privatization of Swedish Welfare Services in the 1990s

During the 1990s, the Swedish welfare state was declared by some to be in a “crisis”, due to both financial strain and loss of political support. Others have argued that the spending cuts and reforms undertaken during this period did slow down the previous increase in social spending, but left the system basically intact. The main argument put forward in this article is that the Swedish welfare state has been and is still undergoing a transforming process whereby it risks losing one of its main characteristics, namely the belief in and institutional support for social egalitarianism. During the 1990s, the public welfare service sector opened up to competing private actors. As a result, the share of private provision grew, both within the health‐care and primary education systems as well as within social service provision. This resulted in a socially segregating dynamic, prompted by the introduction of “consumer choice”. As will be shown in the article, the gradual privatization and market‐orientation of the welfare services undermine previous Swedish notions of a “people's home”, where uniform, high‐quality services are provided by the state to all citizens, regardless of income, social background or cultural orientation.     

Decision process of allocating projects to project managers

Allocating projects to project managers (PM) is a crucial decision in project management. Choosing the PM must be undertaken in a structured way, and thereby take into account the needs of the project and the PM’s competences and availability. The proposed model optimises the total time that PMs have available and takes into account the constraint of the switchover time loss within the mathematical programming. It model is part of a three-stage approach where: (1) projects are sorted using a multicriteria approach; (2) PMs are sorted using a multicriteria approach; and (3) the final allocation to intra-classes of projects is made using the optimisation model. This proposal contributes to aiding decision-makers involved in allocating projects: by respecting the limit of the time that PMs have available, or by extrapolating PMs’ available hours in which case overtime will have to be used. The model is applied in a Brazilian Energy Company.     

On estimation and influence diagnostics for log-Birnbaum–Saunders Student-t regression models: Full Bayesian analysis

The purpose of this paper is to develop a Bayesian approach for log-Birnbaum–Saunders Student-t regression models under right-censored survival data. Markov chain Monte Carlo (MCMC) methods are used to develop a Bayesian procedure for the considered model. In order to attenuate the influence of the outlying observations on the parameter estimates, we present in this paper Birnbaum–Saunders models in which a Student-t distribution is assumed to explain the cumulative damage. Also, some discussions on the model selection to compare the fitted models are given and case deletion influence diagnostics are developed for the joint posterior distribution based on the Kullback–Leibler divergence. The developed procedures are illustrated with a real data set.     

Residents’ preferred policy actions for shrinking cities

Cities facing a continued and prolonged process of population decline require innovative urban regeneration policies complementary to growth-oriented policies. Losing inhabitants involves a decrease in economic activity and social capital. Therefore citizens’ participation in defining policies to cope with population decline is being increasingly advocated. This research focused on four shrinking cities of Portugal to capture residents’ knowledge about the strengths and weaknesses of their city of residence as well as the policies and actions they prioritized for dealing with the population decline. The responses from 701 questionnaires show that economic revival policies as well as safety and accessibility policies were preferred. To put these policies into action, the recovery of industrial activity, the creation of business incubators, an improvement in law enforcement, and public lighting were ranked as top priorities. Rank-ordered logistic regression models were used to understand which variables influenced the residents’ rankings. We found that the evaluation of the city's characteristics impact the ranking of the policies and actions. Hence, residents show a high level of coherence when engaging in a discussion at the level of policy-making. Therefore, the findings support residents’ involvement in decision-making processes regarding urban regeneration in shrinking cities.     

Neuropathology in Alzheimer's disease: awaking from a hundred-year-old dream

For one hundred years after Alois Alzheimer's first report of Alzheimer's disease (AD) in 1906, the pathological hallmarks of the disease, senile plaques and neurofibrillary tangles (NFTs), have been attractive targets for researchers. Therefore, not surprisingly, efforts to understand disease mechanisms have concentrated on the cell biology of amyloid-beta (Abeta) deposition as senile plaques or on the phosphorylation and aggregation of tau as NFTs. However, it now appears that this focus on pathology as a central contributor to disease may be misguided. Indeed, neurons associated with Abeta and NFTs in AD brain show a decrease in oxidative damage relative to those in vulnerable but morphologically intact areas of the brain, suggesting that neurodegenerative lesions are compensatory phenomena, and thus manifestations of cellular adaptation. That Abeta and tau accumulations indicate an age-related physiological reaction to chronic stress calls into question the rationale of current therapeutic efforts targeted toward lesion removal. Moreover, if this concept holds true for pathology in other neurodegenerative diseases, we may need to restructure our thinking and undergo a paradigm shift before substantial progress can be made in therapeutic intervention.     

‘Full‐time is a Given Here’: Part‐time Versus Full‐time Job Quality*

This study explores full‐time workers' understanding of and assumptions about part‐time work against six job quality components identified in recent literature. Forty interviews were conducted with employees in a public sector agency in Australia, a study context where part‐time work is ostensibly ‘good quality’ and is typically long term, voluntary, involving secure contracts (i.e. permanent rather than casual) and having predictable hours distributed evenly over the week and year. Despite strong collective bargaining arrangements as well as substantial legal and industrial obligations, the findings revealed some serious concerns for part‐time job quality. These concerns included reduced responsibilities and lesser access to high status roles and projects, a lack of access to promotion opportunities, increased work intensity and poor workplace support. The highly gendered, part‐time labour market also means that it is women who disproportionately experience this disadvantage. To foster equity, greater attention needs to focus on monitoring and enhancing job quality, regardless of hours worked.     

Women and Access to Political Office: a Comparison of Female and Male State Legislators

The status of women in state legislatures is examined in terms of representation across the United States. A sample of female state legislators and a sample of male state legislators are compared on social and political career characteristics, including marital status, education, occupation, age when one began serving, election mobility, party leadership, and tenure. Party leadership, education, age and, to a lesser extent, occupation were found to distinguish female from male legislators. But party leadership significantly differentiated only between female and male legislators with less than a college degree. Overall, access to state legislative office seems to depend on the same characteristics which define success in society as a whole; for certain groups of women, however, achievement within party ranks provides an alternative mechanism to this end.
