Racism and Xenophobia

Racism is perhaps the most serious basic problem affecting the welfare of people referred to as migrants or black people in Europe today. Racism is not just about personal racial prejudice but also about institutional processes, ways of thinking and ways of doing things that are deeply ingrained in European culture, including health care—especially mental health care. The prevention of racism in a health service requires a clear statement of intent in a race equality policy that generates monitoring systems, action plans and forward planning. Combating racism must go hand‐in‐hand with the promotion of cultural sensitivity in health care; equal opportunities in access to a service must be balanced by strict control of institutional racism in the quality of the service and employment practices.     

Semiparametric Bayesian classification with longitudinal markers

Summary.  We analyse data from a study involving 173 pregnant women. The data are observed values of the β human chorionic gonadotropin hormone measured during the first 80 days of gestational age, including from one up to six longitudinal responses for each woman. The main objective in this study is to predict normal versus abnormal pregnancy outcomes from data that are available at the early stages of pregnancy. We achieve the desired classification with a semiparametric hierarchical model. Specifically, we consider a Dirichlet process mixture prior for the distribution of the random effects in each group. The unknown random-effects distributions are allowed to vary across groups but are made dependent by using a design vector to select different features of a single underlying random probability measure. The resulting model is an extension of the dependent Dirichlet process model, with an additional probability model for group classification. The model is shown to perform better than an alternative model which is based on independent Dirichlet processes for the groups. Relevant posterior distributions are summarized by using Markov chain Monte Carlo methods.     

Mexican Immigrants,Labour Market Assimilation and the Current Population: The Sensitivity of Results Across Seemingly Equivalent Surveys

In this paper we compare estimates of immigrants’ labour supply assimilation profiles using the Current Population Survey Annual Demographic Files (March ADS) and the Current Population Survey Outgoing Rotation Groups (ORGs). We use a measure that is seemingly consistent across both surveys: usual weekly hours of work in the main job. This measure is not only important as it measures the intensive margin of labour supply, but it is also used to estimate hourly earnings in both surveys. Our results indicate that the two surveys produce dramatically different estimates of the change in average hours of work as immigrants’ years in the United States increase: estimates from the March ADS predict much steeper hour's assimilation profiles than do estimates obtained from the ORGs. These differences persist if we include controls for demographic characteristics, and only disappear once we control for occupation heterogeneity. We argue that these differences stem from two separate factors that differentiate the data. First, the ADS and ORG frame the usual “hours worked” question differently. Also, differences in the timing of the surveys may produce seasonality effects that differentially affect the composition of recent and earlier migrants, thereby changing assimilation profiles.     

Bayesian boundedly rational agents play the Finitely Repeated Prisoner's Dilemma

In this paper a model of boundedly rational decision making in the Finitely Repeated Prisoner's Dilemma is proposed in which: (1) each player is Bayesianrational; (2) this is common knowledge; (3) players are constrained by limited state spaces (their Bayesian minds) in processing (1) and (2). Under these circumstances, we show that cooperative behavior may arise as an individually optimal response, except for the latter part of the game. Indeed, such behaviorwill necessarily obtain in long enough games if belief systems satisfy a natural condition: essentially, that all events consistent with the players' analysis of the game be attributed by them positive (although arbitrarily small) subjective probability.     

Flexible models for non-equidispersed count data: comparative performance of parametric models to deal with underdispersion

AStA Advances in Statistical Analysis - Count data as response variables are commonly modeled using Poisson regression models, which require equidispersion, i.e., equal mean and variance. However,...     

Work of gravediggers and health

Gravediggers have death as object of their work. Their activities are painful, physically and mental demanding, as well as unhealthy. Literature is scarce about this theme. The aim of this study is to evaluate gravediggers' work activities and health consequences. The methodological frame which guided this study was Dejours' psychic suffering and its association with the psychodynamic aspects of work. Data collection took place in April-May 2011 in one public and one private cemetery of S?o Paulo, Brazil. Four male workers, aged between 45 to 60 years old were interviewed. Their work activities were observed during a workday. Participants reported their life dreams, defense mechanisms and frustration. The discourse of gravediggers showed serious problems associated to physical and mental demands, public invisibility and/ or social devaluation of work. The most important physical symptom was body pain. In spite this is a preliminary study, it was possible to raise a number of work stressors and health outcomes of gravediggers, an "invisible" worker of our society.     

Regionalization vs. globalization in advertising research: Insights from five decades of academic study

This paper is a response to calls for more research into the regional–as opposed to global–level of international business operations (Rugman and Verbeke, 2004). Focusing on a key issue in international management, the standardization decision, this paper presents a systematic review of top journal articles published over the last five decades on the subject of advertising standardization at the regional level. The results of this review demonstrate that in the last decade studies have frequently taken a regional rather than international focus of analysis, suggesting a shift in research in line with regionalization theory. However, this study also shows that research on regional standardization has lacked consistency in relation to how the phenomenon should be defined and measured. We present a conceptualization of measurement approaches to international advertising standardization, propose a typology of approaches and discuss their implications for knowledge advancement in the area.     

Do Absentee Voters Differ from Polling Place Voters?: New Evidence from California

In the 2003 California gubernatorial recall election 2,775,785absentee ballots were cast, representing about 30 percent ofall voters statewide. Given the number of absentee ballots andthe increasing propensity for voters in California and elsewhereto choose this voting method, we some basic questions: Who areabsentee voters, and are they different from polling place voters?To answer these questions, we fielded a statewide survey ofabsentee voters in the days before the October 7 recall election,asking respondents why they voted absentee, their partisan andideological preferences, demographic characteristics, and otherrelevant questions. We find that absentee voters do not differsignificantly from the overall state electorate in terms oftheir vote preferences, despite being older and better educated.For example, 56 percent of absentee voters in our survey voted"yes" on the recall, compared with 55 percent for the entirestate, according to official returns. Further, absentee votersfavored Arnold Schwarzenegger over Cruz Bustamante by a considerablemargin, similar to the overall election results. We found partyregistration among absentee voters to be nearly identical tostatewide partisan registration.
