Temporary Labour–Migration System and Long–term Residence Strategies in the United Arab Emirates

The United Arab Emirates’ migration system, the sponsorship–based kafala system, is defined as a temporary labour–migration regime. Although there are policies making permanent residence unattainable for virtually all migrants, it is still relevant to explore the temporality of migrations in the UAE. The purpose of this study is to investigate developments in migration, migration policies and population trends in the country, including trends that concern the duration of migrants’ stay. We also identify some of the major strategies used by migrants to prolong their sojourn in the UAE. It is maintained that the migrant stock has increased continuously in the last decades and that a large number of migrants devise strategies to continue their residence and remain in the country for years. The authors also identify and discuss migrants’ transition within and in-between regularity and irregularity, and analyse the reasons for utilizing different strategies over time.

Working with Signs of Safety: Parents' perception of change

Signs of Safety (SoS) is an approach used to work with families involved with children's services that was developed in Australia during the 1990s. Despite the fact that it has been adopted by countries across the globe, the evidence for its effectiveness in relation to improved outcomes for children has not been established. This study attempted to take an initial step in measuring the impact of SoS on families. In the course of evaluating SoS in 10 areas across England, the authors collected data from social workers using the approach and from families with whom they were working who also gave permission for their case records to be examined. Where social workers were more confident about using SoS and had consistently applied its elements, more families reported improvements in their lives. Families with social workers who had higher confidence in using SoS were also more likely to say that they had achieved more than expected against their earlier stated goals and were more likely to report positively against self‐defined goals.     

On the equilibrium of voting games with abstention and several levels of approval

We study the core of “(j, k) simple games”, where voters choose one level of approval from among j possible levels, partitioning the society into j coalitions, and each possible partition facing k levels of approval in the output (Freixas and Zwicker in Soc Choice Welf 21:399–431, 2003). We consider the case of (j, 2) simple games, including voting games in which each voter may cast a “yes” or “no” vote, or abstain (j = 3). A necessary and sufficient condition for the non-emptiness of the core of such games is provided, with an important application to weighted symmetric (j, 2) simple games. These results generalize the literature, and provide a characterization of constitutions under which a society would allow a given number of candidates to compete for leadership without running the risk of political instability. We apply these results to well-known voting systems and social choice institutions including the relative majority rule, the two-thirds relative majority rule, the United States Senate, and the United Nations Security Council.     

Role of Clinical Diagnosis and Medication Use in Effects of Maternal Depression on Infant‐Directed Speech

Infant‐directed (ID) speech was recorded from mothers as they interacted with their 4‐ to 12‐month‐old infants. Hierarchical regression analyses revealed that two variables, age of the mother and mother's diagnosed depression, independently accounted for significant proportions of the variance in the extent of change in fundamental frequency (ΔF0). Specifically, depressed mothers produced ID speech with smaller ΔF0 than did nondepressed mothers, and older mothers produced ID speech with larger ΔF0 than did younger mothers. Mothers who were taking antidepressant medication and who were diagnosed as being in at least partial remission produced ID speech with mean ΔF0 values that were comparable to those of nondepressed mothers. These results demonstrate explicit associations between major depressive disorder and an acoustic attribute of ID speech that is highly salient to young infants.     

Chisquared and related inducing pivot variables: an application to orthogonal mixed models

Abstract

We use chi-squared and related pivot variables to induce probability measures for model parameters, obtaining some results that will be useful on the induced densities. As illustration we considered mixed models with balanced cross nesting and used the algebraic structure to derive confidence intervals for the variance components. A numerical application is presented.     

Timber,Minerals, and Social Change: An Exploratory Test of Two Resource-Dependent Communities1

Abstract There are few empirical tests of the relationship between local resource production and community social systems. This paper reports the results of research on two communities in northern Idaho: one timber-dependent, the other mining-dependent. Data were collected for 13 indicators of resource production and 15 indicators of social change for periods up to 65 years. Regression analysis was used to test if community social change is associated with the production level of local resource systems. The final models support the hypothesis in both communities. The form, lag condition, and strength of the relationship is complex and may vary with the dependent indicator. The original causal image—the rural community with a social order that directly responds to changes in local resource production—is blurred. Suggestions are made for future research.     

Chloroform Exposure and the Health Risk Associated with Multiple Uses of Chlorinated Tap Water

Recently, showers have been suspected to be an important source of indoor exposure to volatile organic compounds (VOC). The chloroform dose to an individual from showering was determined based on exhaled breath analysis. The postexposure chloroform breath concentration ranged from 6.0-21 micrograms/m3, while all corresponding background breath concentrations were less than 0.86 micrograms/m3. The internal dose from showering (inhalation plus dermal) was comparable to estimates of the dose from daily water ingestion. The risk associated with a single, 10-min shower was estimated to be 1.22 x 10(-4), while the estimated risk from daily ingestion of tap water ranged from 0.130 x 10(-4) to 1.80 x 10(-4) for 0.15 and 2.0 L, respectively. Since the estimates of chloroform risk from domestic water use for the three exposure routes--ingestion, inhalation, and dermal--are similar, all routes must be used to calculate the total risk when making policy decisions regarding the quality of the municipal water supply.
