Becoming Overweight without Gaining a Pound: Weight Evaluations and the Social Integration of Mexicans in the United States

Mexican women gain weight with increasing duration in the United States. In the United States, body dissatisfaction tends to be associated with depression, disordered eating, and incongruent weight evaluations, particularly among white women and women of higher socioeconomic status. However, it remains unclear how being overweight and obesity are interpreted by Mexican women. Using comparable data of women aged 20–64 from both Mexico (the 2006 Encuesta Nacional de Salud y Nutricion; N = 17,012) and the United States (the 1999–2009 National Health and Nutrition Examination Surveys; N = 8,487), we compare weight status evaluations among Mexican nationals, Mexican immigrants, US‐born Mexicans, US‐born non‐Hispanic whites, and US‐born non‐Hispanic blacks. Logistic regression analyses, which control for demographic and socioeconomic variables and measured body mass index and adjust for the likelihood of migration for Mexican nationals, indicate that the tendency to self‐evaluate as overweight among Mexicans converges with levels among non‐Hispanic whites and diverges from blacks over time in the United States. Overall, the results suggest a US integration process in which Mexican‐American women's less critical self‐evaluations originate in Mexico but fade with time in the United States as they gradually adopt US white norms for thinner body sizes. These results are discussed in light of prior research about social comparison and negative health assimilation.     

Giving birth: Expectations of first time mothers in Switzerland at the mid point of pregnancy

Problem and background

Despite a generally affluent society, the caesarean section rate in Switzerland has steadily climbed in recent years from 22.9% in 1998 to 33.7% in 2014. Speculation by the media has prompted political questions as to the reasons. However, there is no clear evidence as to why the Swiss rate should be so high especially in comparison with neighbouring countries.

Anthropometric change: implications for office ergonomics

Well-designed office workspaces require good anthropometric data in order to accommodate variability in the worker population. The recent obesity epidemic carries with it a number of anthropometric changes that have significant impact on design. We examine anthropometric change among US civilians over the last 50 years, and then examine that change in a subset of the US population--the US military--as military data sets often have more ergonomic dimensions than civilian ones. The civilian mean stature increased throughout the period 1962 to 2006 for both males and females. However, the rate of increase in mean weight was considerably faster. As a result, the male obesity rate changed from 10.7% in 1962 to 31.3% in 2006. The female change for the same period was 15.8% to 33.2%. In the Army, the proportion of obesity increased from 3.6% to 20.9%, in males. In the absence of national US ergonomic data, we demonstrate one approach to tracking civilian change in these dimensions, applying military height/weight regression equations to the civilian population estimates. This approach is useful for population monitoring but is not suitable for establishing new design limits, as regression estimates likely underestimate the change at the ends of the distribution.     

A Generalized Estimating Equations Approach for Analysis of the Impact of New Technology on a Trawl Fishery

The article describes a generalized estimating equations approach that was used to investigate the impact of technology on vessel performance in a trawl fishery during 1988–96, while accounting for spatial and temporal correlations in the catch-effort data. Robust estimation of parameters in the presence of several levels of clustering depended more on the choice of cluster definition than on the choice of correlation structure within the cluster. Models with smaller cluster sizes produced stable results, while models with larger cluster sizes, that may have had complex within-cluster correlation structures and that had within-cluster covariates, produced estimates sensitive to the correlation structure. The preferred model arising from this dataset assumed that catches from a vessel were correlated in the same years and the same areas, but independent in different years and areas. The model that assumed catches from a vessel were correlated in all years and areas, equivalent to a random effects term for vessel, produced spurious results. This was an unexpected finding that highlighted the need to adopt a systematic strategy for modelling. The article proposes a modelling strategy of selecting the best cluster definition first, and the working correlation structure (within clusters) second. The article discusses the selection and interpretation of the model in the light of background knowledge of the data and utility of the model, and the potential for this modelling approach to apply in similar statistical situations.     

Integrating education: Parekhian multiculturalism and good practice

This paper explores the concept of good practice in integrating education in divided societies. Using Northern Ireland as a case study, the paper draws on data from eight schools (both integrated Catholic and Protestant, and separate) that are identified as exemplifying good practice in response to cultural diversity. Analysis is provided through the lens of Bhikhu Parekh’s reconceptualization of multiculturalism from 2006 Parekh, B. 2006. Rethinking multiculturalism: Cultural diversity and political theory, , 2nd ed., Hampshire and New York: Palgrave Macmillan.  [Google Scholar]. The data provide insights into characteristics of good practice from the perspectives of pupils, support staff, teachers and principals, in a society that is not only moving out of conflict but is also responding to the challenges of incoming minority students.     

Becoming involved in raising a relative's child: reasons, caregiver motivations and pathways to informal kinship care

Interviews with 207 informal kinship caregivers describe a dynamic process that influences how children come to live with a relative other than their parent. This process involves three overlapping and often simultaneously occurring factors: (1) the reasons the children's parents were unable to care for them; (2) the caregiver's motivation for assuming responsibility for the child; and (3) the pathways or routes that children took to the caregiver's home. Understanding these factors and their mutual and simultaneous influence is important as we shape policies, programs and interventions to support families as they consider whether to care for a relative's child and once they assume this responsibility.     

Probabilistic Principal Component Analysis

Principal component analysis (PCA) is a ubiquitous technique for data analysis and processing, but one which is not based on a probability model. We demonstrate how the principal axes of a set of observed data vectors may be determined through maximum likelihood estimation of parameters in a latent variable model that is closely related to factor analysis. We consider the properties of the associated likelihood function, giving an EM algorithm for estimating the principal subspace iteratively, and discuss, with illustrative examples, the advantages conveyed by this probabilistic approach to PCA.     

Promise or Problem? A Review of the Literature on Men Working in Early Childhood Services

Few men care for, or teach, young children. The 1991 UK census found that less than 1% of nursery nurses were male, while 14% of nursery/primary teachers were male. A similarly gendered picture can be found across European, North American and Australian studies of early childhood services, such as childcare centres and early education. The practice and prospect of men early childhood workers are both encouraged and resisted. The aim of this article is to review the international literature relevant to men working in early childhood services with pre‐school‐aged children. The case for male early childhood workers is reviewed: two pertinent themes from the related field of men working in non‐traditional occupations are highlighted. The review considers how these are applied to the specific context of men and early childhood services. Four aspects of the debate about men and early childhood work are examined: gender stereotypes; senior positions; gendered motives; and risks, allegations and protection. The literature suggests that men's careers have much to gain from working in early childhood services, but that, certainly in the Anglo‐American literature, a recurring theme is the representation of men early childhood workers as a source of suspicion.     

Does defending affect adolescents' peer status,or vice versa? Testing the moderating effects of empathy,gender, and anti-bullying norms

This study examined bidirectional associations between students' bully-directed defending behavior and their peer status (being liked or popular) and tested for the moderating role of empathy, gender, and classroom anti-bullying norms. Three waves of data were collected at 4–5-month time intervals among 3680 Finnish adolescents (M_age = 13.94, 53.0% girls). Cross-lagged panel analyses showed that defending positively predicted popularity and, to a larger degree, being liked over time. No moderating effect of empathy was found. Popularity was more strongly predictive of defending, and defending was more strongly predictive of status among girls than among boys. Moreover, the positive effects of both types of status on defending were—albeit to a limited extent—stronger in classrooms with higher anti-bullying norms.
