Understanding the Socioeconomic Status of International Immigrants in Chile Through Hierarchical Cluster Analysis: a Population‐Based Study

Immigration to Chile is not large (just under 2% of the total population) but has increased in recent years. This study aimed to analyse the socioeconomic status (SES) of immigrants in Chile and compare it with the Chilean‐born, by secondary data analysis of an anonymous nationally representative survey (CASEN, 2006). Immigrants are categorized into Low, Medium and High SES through hierarchical cluster analysis. Around 1 per cent of the total sample are international immigrants; an additional 0.7 per cent did not report their migration status. Self‐reported immigrants show great variability in their SES. Immigrants in the Low SES cluster appeared to be significantly younger than those in Medium and High SES, also more likely to be children, women and belong to an ethnic minority. Immigrants in the Low SES cluster appeared similar to the unemployed, poorest Chilean‐born but are more than eight years younger on average and more likely to be female. Immigrants to Chile are a unique group, with socio‐demographic characteristics that differ significantly from the Chilean‐born population, but there is great heterogeneity and complexity within this group. Cluster analysis provided a meaningful interpretation of the multidimensional concept of SES and allowed the identification of a vulnerable group of Low SES immigrants to Chile.     

Living Arrangements of American Urban Widows

Abstract

This paper is devoted to the examination of the residential arrangements of widows and of the reasons they do not live with married children. It is based on interviews with a modified area probability sample of 301 widows, aged 50 and over, residing in metropolitan Chicago. The conclusion of the analyses is that older widows expect problems in living with married children or are enjoying the ease and independence of living alone sufficiently to offset its disadvantages. Although one-quarter of the widows live in arrangements which they do not like, in terms of sharing a residence, most express satisfaction with their current location. The tendency toward, and satisfaction with, independent living is associated with age, education, and attitudes toward selected social relations, particularly toward children. Widows sharing a residence tend to be with never married children or those undergoing a disorganization of their marriage and to be the head of such a household. Very few Chicago area widows live in three-generation families.     

Methylmercury Risks and EPA + DHA Benefits Associated with Seafood Consumption in Europe

The intake of methyl‐Hg and EPA + DHA through consumption of seafood in Europe as well as the associated probability of exceeding the provisional tolerable weekly intake (PTWI) and the recommended daily intake (RDI), respectively, were estimated by combining methyl‐Hg and EPA + DHA contents in the five most consumed seafood species with hypothesized consumption distributions for eight European countries, chosen on the basis of size and representative significance. Two estimators were used: plug‐in (PI) and tail estimation (TE). The latter was based on the application of the extreme value theory to the intakes distribution curves. Whereas contents data were collected from own database and published scientific papers, consumption data were obtained from statistical sources of the various countries. Seafood consumption levels varied considerably between countries, from 140 in the United Kingdom to 628.5 g/(person.week) in Iceland. The main consumed species were also different between countries. The probability of exceeding the methyl‐Hg PTWI ranged from 0.04% in the United Kingdom to 9.61% in Iceland. Concerning the probability of exceeding the RDI of EPA + DHA, Iceland was third, after Portugal (66.05%) and Spain (61.05%) and the United Kingdom was the last (0.32%). While TE was most accurate for small probabilities, PI yielded best estimates for larger probabilities.     

Market Access and Manufacturing Wages: Evidence for the Enlarged EU

This paper shows that the establishment of market access to the new EU member countries can favour manufacturing wages in larger EU members, but not in smaller ones, although within the latter some sectors may have gains. Hence the impact of market access is country and sector-specific. The variation in country size, as measured by GDP, is highly correlated with the variation in the impact of market access to the new EU member countries on manufacturing wages.     

Pseudo-likelihood inference for clustered binary data

The maximum likelihood procedure to estimate paraneters of a model has scveral attractive properties including the existence of the covariance matrix which yield asymptotic covariances: for a sample size N the asymptotics are in general of order 1/N. Here we give an asymptotic for the skewness of the distribution of the maximum likelihood estimator of a parameter; this is of order 1/ n2 and this expression is new. Applications relate to the parameters of (i) the Poisson, binomial, and normal density. (ii) the gamna density and (iii) the Beta debsity. Other application are being considered. The expression for the asymptotic skowness at one phase of the study tured out to be unusually complicated involving the asymptotic expressions for variance and bias. When these were identified a much simpler compact expression appeared which we now describe. The work is a much improved treatment of the subject described in Shenton and Bowman (Mariunm likelihood estimation in small samples, Griffin. 1977).     

Student Functioning,Concerns, and Socio-Personal Well-Being

The following study used the Student Quality of Lifeand Satisfaction (SQOLAS) instrument and 467University of Rhode Island undergraduate and graduatestudents as participants in order to examinerelationships among functioning and performancevariables, student concern and importance areas, andmeasures of socio-personal satisfaction andwell-being. Canonical correlational analysis revealedtwo statistically significant canonical correlationsbetween a student functioning/performance variable setand a concern/importance area variable set. A set ofvariables related to increased concern and importanceratings of socio-sexual behavior, and decreasedratings of crime, violence, multicultural, and genderissues was significantly associated with a second setof variables: increased levels of alcohol use andassociated negative consequences, younger age,increased mental health concerns, men more than women,decreased class year, and less positive ratings towarddirection in life. Standard multiple regressionanalysis produced a statistically significant modelwhere positive attitude towards direction in life canbe predicted by higher levels of socio-personalsatisfaction and deep metacognitive processing, andlower levels of alcohol use and associated negativeconsequences, and fewer mental health concerns.Implications of the results are discussed in relationto theories of cognitive behavior, phenomenologicalfunctioning, life meaning, and well-being.     

Relationships between Borda voting and Zermelo ranking

There are many situations wherein a group of individuals (e.g., voters, experts, sports writers) must produce an ordered list of ‘best’ alternatives selected from a given group of alternatives (e.g., candidates, proposals, sports teams). Two long established mechanisms that have been used for this task are ‘Zermelo’s Ranking Method’ (1929) and ‘Borda’s Voting Scheme’ (1781). The main purpose of this paper is to point out that they are, under certain common circumstances, identical. We then show that Zermelo’s Method can be used in situations that Borda’s Method is not designed to handle.     

HCBS Spending and Nursing Home Admissions for 1915(c) Waiver Enrollees

Medicaid waiver programs for home- and community-based services (HCBS) have grown rapidly and serve a population at high risk for nursing home (NH) admission. This study utilized the Medicaid Analytic Extract Personal Summary File and the NH Minimum Data Set and tested whether higher levels of per-beneficiary HCBS spending were associated with (1) lower risk of long-term (90+ days) NH admission and (2) higher functional/cognitive impairment at admission for new enrollees in 1915(c) aged or aged and disabled waiver programs. Waiver enrollees in states and counties with higher HCBS spending were found to have lower risk of long-term NH admission and greater functional impairment at NH admission compared to waiver enrollees in states and counties with lower spending. This indicates that higher per-enrollee HCBS spending may enable waiver enrollees to remain in the community until their functional impairment becomes more severe.     

The challenges of interdisciplinary education and its application on teaching ergonomics

The education in Brazil is still strongly based on traditional teaching methods that reinforce a passive attitude of the student. Despite the educational guidelines indicate the need for more liberating and interdisciplinary methodologies, there are few actions for change. Within this context, interdisciplinary appears as an important tool to help the creation of a new thinking in education, proposing the connection between the parts of an area of knowledge. In this way leading the student to develop a more critical and reflective thinking about the reality of the community where he lives. Being understood ergonomics as a scientific discipline that looks for the interactions among humans and other elements of a system in order to optimize human well-being and overall system performance, interdisciplinary has become essential in this process. The aim of this study was to discuss the educational foundations of interdisciplinarity and their applicability in the teaching of ergonomics in the context of Brazil.
