A Test of Basic Assumptions of Affective Events Theory (AET) in Call Centre Work1

Based on data from 2091 call centre representatives working in 85 call centres in the UK, central assumptions of affective events theory (AET) are tested. AET predicts that specific features of work (e.g. autonomy) have an impact on the arousal of emotions and moods at work that, in turn, co‐determine job satisfaction of employees. AET further proposes that job satisfaction is an evaluative judgement that mainly explains cognitive‐based behaviour, whereas emotions and moods better predict affective‐based behaviour. The results support these assumptions. A clear separation of key constructs (job satisfaction, positive and negative emotions) was possible. Moreover, correlations between several work features (e.g. supervisory support) and job satisfaction were, in part, mediated by work emotions, even when controlling for gender, age, call centre type (in‐house versus outsourced centres) and call centre size. Predictions regarding consequences of satisfaction and affect were partly corroborated as continuance commitment was more strongly related to job satisfaction than to positive emotions. In addition, affective commitment and health complaints were related to both emotions and job satisfaction to the same extent. Thus, AET is a fruitful framework for explaining why and how specific management strategies used for designing work features influence important organizational attitudes and well‐being of employees.     

Social Protection and Health: Experiences in Uganda

There is an interesting and continuing debate on the nature and role of social protection in poverty reduction. Within the health sector, discussion has focussed on the drawbacks associated with fee exemption schemes and community‐based health insurance, with much less attention paid to the policy option of abolishing user fees. This paper reviews empirical evidence on the impact of the Government of Uganda's decision in 2001 to abolish user fees for health services. The paper finds that this policy intervention has had a significant positive impact on health‐seeking behaviour in Uganda and concludes that this policy measure can make an important contribution towards a more ‘promotional’ policy approach to social protection.

Investigating Race,Class and Context through Historical Evidence: Segregation and the Ecology of Aspirations of Black College Students in the 1960s South

In an era of re-segregation among school systems in the United States, we find ourselves revisiting times of forced school segregation (pre Brown v. Board) for a better understanding of explanations and potential consequences. One consequence, depressed aspirations for occupational mobility, is examined here. Using data for Mathews and Prothro's Negro Participation Survey, administered to black college students in 1961, we examine this relationship while controlling for various individual level indicators of capital, demographics, political participation, and ecologically-centered organizational and economic factors through the use of Hierarchical Linear Modeling (HLM). We uncover patterns of aspirations (or lack thereof) concerning social class mobility that are directly related to social class background and the cultural orientations of the environment in which the student hails. Our conclusions link such patterns to the current trajectory of re-segregation in the education system.     

Bayesian variable selection for multioutcome models through shared shrinkage

Variable selection over a potentially large set of covariates in a linear model is quite popular. In the Bayesian context, common prior choices can lead to a posterior expectation of the regression coefficients that is a sparse (or nearly sparse) vector with a few nonzero components, those covariates that are most important. This article extends the “global‐local” shrinkage idea to a scenario where one wishes to model multiple response variables simultaneously. Here, we have developed a variable selection method for a K‐outcome model (multivariate regression) that identifies the most important covariates across all outcomes. The prior for all regression coefficients is a mean zero normal with coefficient‐specific variance term that consists of a predictor‐specific factor (shared local shrinkage parameter) and a model‐specific factor (global shrinkage term) that differs in each model. The performance of our modeling approach is evaluated through simulation studies and a data example.     

Support for torture over time: Interrogating the American public about coercive tactics

In this study, we examine what influences public attitudes toward torture and whether the public's attitude affects or is affected by shifts in presidential policy on torture. We employed ten surveys over five years that looked at approval of torture, as well as two surveys that asked questions about specific methods. We find that public support for torture has risen mildly, but a resilient ambivalence best describes the public's attitude. The public was not affected by the change in government from an administration that strongly supported enhanced interrogation techniques to one that opposed them, and labeled them torture. Public opinion also seemed unaffected by the increased criticism of torture generally. Large majorities oppose most specific methods of interrogation, while at times a majority supports torture in general. We also find support for torture and specific methods is affected most strongly by partisanship and ideology.     

The Performance of Periodic Autoregressive Models in Forecasting Seasonal U.K. Consumption

The parameters of a periodic model are allowed to vary according to the time at which observations are made. Periodic autoregressive models are fitted to the quarterly values of seasonally unadjusted real nondurable consumers' expenditure for the United Kingdom and its components. The periodic model offers no improvement over conventional specifications if the aggregate is modeled directly. On the other hand, periodic models generally perform well for the components, which contain additional seasonal information. The choice between a periodic or nonperiodic specification is also shown to have an important influence on the resulting dynamic properties.     

Can Body Mass Index (BMI) be used as a proxy for somatotype?

In a paper published in The Social Science Journal, Maddan et al. [Maddan, S., Walker, J. T., & Miller, J. M. (2008). Does size really matter? A reexamination of Sheldon's somatotypes and criminal behavior. The Social Sciences Journal, 45, 330–344.] proposed that Body Mass Index (BMI) can be used as proxy for somatotype, a quantitative system for describing body build, in social science research. This paper tests this proposal using a sample of 200 males from an archival data set collected by Sheldon [Sheldon, W. H. (1942). The varieties of temperament: A psychology of constitutional differences (with S.S. Stevens). New York: Harper and Row Publishers.]. The data included somatotype data, height, and weight. BMI was calculated and individuals were assigned to the categories endomorph, mesomorph, and ectomorph based on the Maddan et al. BMI criteria. The BMI method was only able to correctly classify 110 individuals, 55% of the sample. This finding suggests that BMI is an inadequate proxy for somatotype.
