An experiment in primary health care provision

Missing data and, more generally, imperfections in implementing a study design are an endemic problem in large scale studies involving human subjects. We present an analysis of an experiment in the interaction between general practitioners and their patients, in which the issue of missing data is addressed by a sensitivity analysis using multiple imputation. Instead of specifying a model for missingness we explore certain extreme ways of departing from the assumption of data missing at random and establish the largest extent of such departures which would still fail to supplant the evidence about the studied effect. An important advantage of the approach is that the algorithm intended for the complete data, to fit generalized linear models with random effects, is used without any alteration.     

Chinese and Americans Agree on What Is Fair,but Disagree on What Is Best in Societal Decisions Affecting Health and Safety Risks

Through surveys of students and junior professionals and interviews with business and government executives, we studied Chinese choices and fairness perceptions in risky health and safety decisions. The survey responses were compared with American responses from an earlier study by Keller and Sarin.The survey results show that the American and Chinese respondents had similar fairness perceptions, but the Chinese did not make decisions that were consistent with their fairness perceptions, whereas the Americans did. We found that the middle-age Chinese professionals tended to make choices that were more different from the Americans than were the choices of the young Chinese management students. It is likely that these discrepancies were caused by cultural differences, with the younger Chinese tending to face a stronger Western influence.The insights from the survey results were enriched by interviews that revealed fairness perceptions of Chinese business and government executives. A framework to interpret cultural influences on decision making was also proposed.

Security or insecurity? Representations of the UK border in public and policy discourses

This article analyses representations of the UK border (in relation to migration) in UK public and policy discourses. It uses methods from corpus linguistics and critical discourse analysis to compare the two discursive domains. A 26 million-word corpus of policy documentation and British newspaper articles published between 2007 and 2014 is examined using the analysis tool Sketch Engine and applying qualitative concordance analysis. The analysis reveals a key difference between the two domains: while the UK border is represented as a security concept in the policy corpus, the corpus of the public newspaper domain frequently and saliently represents the UK border as a concept dominated by insecurity. The article argues that the discursive label of European Union has played a role in contributing to this difference.     

Adolescents’ perception of peer groups: Psychological,behavioral, and relational determinants

Adolescents’ social cognitive understanding of their social world is often inaccurate and biased. Focusing on peer groups, this study examines how adolescents’ psychological, behavioral, and relational characteristics influence the extent to which they accurately identify their own and others’ peer groups. Analyses were conducted with a sample of 1481 seventh- and tenth-grade Chinese students who are embedded with 346 peer groups. Overall, females and older students had more accurate perceptions. In addition, lower self-esteem, higher indegree centrality, and lower betweenness centrality in the friendship network predicted more accurate perception of one’s own groups, whereas higher academic performance and lower betweenness centrality in the friendship network predicted more accurate perception of others’ groups. Implications for understanding the connection between adolescents’ psychological and behavioral traits, social relationships, and social cognition are discussed.

The interpreter as institutional gatekeeper: The social-linguistic role of interpreters in Spanish-English medical discourse

Increases in immigration have led to an enormous growth in the number of cross-linguistic medical encounters taking place throughout the United States. In this article the role of hospital-based interpreters in cross-linguistic, internal medicine ‘medical interviews’ is examined. The interpreter's actions are analyzed against the historical and institutional context within which she is working, and also with an eye to the institutional goals that frame the patient-physician discourse. Interpreters are found not to be acting as ‘neutral’ machines of semantic conversion, but are rather shown to be active participants in the process of diagnosis. Since this process hinges on the evaluation of social and medical relevance of patient contributions to the discourse, the interpreter can be seen as an additional institutional gatekeeper for the recent immigrants for whom she is interpreting. Cross-linguistic medical interviews may also be viewed as a form of cross-cultural interaction; in this light, the larger political ramifications of the interpreters' actions are explored. ‘Interpreters are the most powerful people in a medical conversation.’ Head of Interpreting Services at a major private U.S. hospital, May 1999.
