Using computerized ambulatory diaries for the assessment of job characteristics and work-related stress in nurses

Much research into work-related stress is based on retrospective self-reports, whereas records made at the time could be more valuable. In this study the primary components of two models of work stress, Karasek's demand-control (DC) model and Siegrist's effort-reward imbalance (ERI), were assessed in trained nurses using ambulatory diaries and traditional questionnaire methods. The diaries were entered on small hand-held computers and the method used has been termed ecological momentary assessment (EMA), in which recordings are made in real time in the working environment. The participants were 36 nurses who completed standardized questionnaires evaluating ERI, strain (from DC model), and, over three shifts, computerized behavioural diaries that measured effort-demand, control, reward, and stress every 90 minutes on average, enabling determination of strain and ERI repeatedly in the work situation. A total of 674 observations were recorded. Using multilevel linear modelling, it was found that the questionnaire and computerized diary derived measures of strain (DC) and ERI were reliably correlated. In addition, the ambulatory measures of both strain (DC) and ERI correlated with ratings of stress taken at the same time. From this study it would appear that ambulatory diaries could be a powerful and flexible way of assessing work related stress and its putative determinants in a real life work setting.     

Pierre Bourdieu and Jacques Rancière on art/aesthetics and politics: the origins of disagreement, 1963–1985

Rancière published two substantial criticisms of the work of Bourdieu in the early 1980s. It is possible that these were provoked by his sense that he needed to oppose what he considered to be the sociological reduction of aesthetic taste offered by Bourdieu in Distinction (Bourdieu 1986 [1979]) at precisely the moment when he (Rancière) was beginning to articulate his commitment to the potential of aesthetic expression as a mode of political resistance. Except in so far as it draws upon some of the retrospective reflections offered by Rancière in his introductions to the re‐issues of his early texts, this paper examines the parallel development of the thinking of the two men up to the mid‐1980s – but not beyond. The discussion is situated socio‐historically and, by definition, does not seek to offer comparatively any transhistorical assessment of the values of the positions adopted by the two men. I argue that Rancière misrepresented the character of Bourdieu's sociological work by failing to recognize the underlying phenomenological orientation of his thinking. Bourdieu suppressed this orientation in the 1960s but, after the May events of 1968, it enabled him to expose the extent to which the practices of both science and art operate within constructed ‘fields’ in strategic distinction from popular primary experience. The challenge is to introduce an ongoing dialogue between primary and constructed cultures rather than to suppose that either social science or art possesses intrinsic autonomy.     

The influence of nonverbal cues associated with looking behavior on young children's mentalistic attributions

The ability of children to use looking behavior as a cue to guide their mentalistic attributions was assessed. In Experiment 1 video displays were presented in which a protagonist faced one of two potential goals, half of the time standing equidistant from both targets and in the remaining trials standing closer to the target not being faced. Preschoolers consistently based their inferences of another's attention and goal on the direction in which the protagonist was facing. However, in Experiments 2 and 3 preschoolers experienced difficulty in correctly inferring an actor's desired goal when the protagonist's body was oriented in a direction opposite of where she was looking. Under these conditions, only young elementary school children consistently inferred that the protagonist's goal was the target being looked at (Experiment 2). The results from these three studies suggest that an important development occurring in childhood is the ability to consistently distinguish gaze from body orientation when inferring the goals of another. The implications of this development for children's understanding of the mind are discussed.     

Change from within: The ABC‐AME church

This article describes the dilemma of a senior pastor whose urban church lost its community focus as the congregation became more affluent. His task was to determine what role the church should play in helping its less fortunate neighbors and how to get the members to support this new vision. Where there is no vision the people perish. —Proverbs 29:18     

Using success to measure quality in British higher education: which subjects attract the best-qualified students?

Summary. A theory is developed to measure the quality of applicants into UK higher education. It is based on the principle that more able applicants will self-select into more difficult subject choices. The advantage is that it gives a unidimensional measure whereby different groups can easily be compared across any dimension of interest, e.g. men, women and the various ethnic groups. Here the relative quality of applicants and acceptances across 170 separate subject groups is calculated and discussed by using a data set with over 2 million observations. It, therefore, offers a way of achieving a more refined measure of the quality of human capital.     

Why is there so much genetic variation for wing dimorphism?

Wing dimorphism appears in general to be determined either by a single locus, 2 allele system in which brachyptery is dominant, or by the additive action of numerous loci. In the latter case studies indicate that the heritability is typically quite large. It is generally postulated that wing dimorphism is under strong selection: why then is genetic variation not eroded? In this paper I consider three possible explanations. First, genetic variation may not be exposed to selection because environmental heterogeneity effectively makes heritability zero. Because wing dimorphisms are known to evolve it seems unlikely that this is the primary factor. Second, directional selection on a threshold trait may push the population almost to monomorphism but erodes genetic variance at a very slow rate. This mechanism cannot preserve variation but makes it possible for other factors to more easily maintain variability. Finally, I demonstrate that in a heterogeneous environment spatio-temporal variation in fitness will itself maintain a genetic polymorphism for wing dimorphism. This paper is dedicated to Professor Sinzo Masaki, whose work on the evolution of wing dimorphism and diapause has been so important to our understanding of the evolution of dimorphic variation.
