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.     

Effectiveness and Efficiency of Controlling Campylobacter on Broiler Chicken Meat

Campylobacter bacteria are an important cause of foodborne infections. We estimated the potential costs and benefits of a large number of possible interventions to decrease human exposure to Campylobacter by consumption of chicken meat, which accounts for 20-40% of all cases of human campylobacteriosis in the Netherlands. For this purpose, a farm-to-fork risk assessment model was combined with economic analysis and epidemiological data. Reduction of contamination at broiler farms could be efficient in theory. However, it is unclear which hygienic measures need to be taken and the costs can be very high. The experimental treatment of colonized broiler flocks with bacteriophages has proven to be effective and could also be cost efficient, if confirmed in practice. Since a major decrease of infections at the broiler farm is not expected in the short term, additional measures in the processing plant were also considered. At this moment, guaranteed Campylobacter-free chicken meat at the retail level is not realistic. The most promising interventions in the processing plant are limiting fecal leakage during processing and separation of contaminated and noncontaminated flocks (scheduling), followed by decontamination of the contaminated flock. New (faster and more sensitive) test methods to detect Campylobacter colonization in broilers flocks are a prerequisite for successful scheduling scenarios. Other methods to decrease the contamination of meat of colonized flocks such as freezing and heat treatment are more expensive and/or less effective than chemical decontamination.     

Consumer Evaluations of Food Risk Management Quality in Europe

In developing and implementing appropriate food risk management strategies, it is important to understand how consumers evaluate the quality of food risk management practices. The aim of this study is to model the underlying psychological factors influencing consumer evaluations of food risk management quality using structural equation modeling techniques (SEM), and to examine the extent to which the influence of these factors is country-specific (comparing respondents from Denmark, Germany, Greece, Slovenia, and the United Kingdom). A survey was developed to model the factors that drive consumer evaluations of food risk management practices and their relative importance (n= 2,533 total respondents). The measurement scales included in the structural model were configurally and metrically invariant across countries. Results show that some factors appear to drive perceptions of effective food risk management in all the countries studied, such as proactive consumer protection, which was positively related to consumers' evaluation of food risk management quality, while opaque and reactive risk management was negatively related to perceived food risk management quality. Other factors appeared to apply only in certain countries. For example, skepticism in risk assessment and communication practices was negatively related to food risk management quality, particularly so in the UK. Expertise of food risk managers appeared to be a key factor in consumers' evaluation of food risk management quality in some countries. However, trust in the honesty of food risk managers did not have a significant effect on food risk management quality. From the results, policy implications for food risk management are discussed and important directions for future research are identified.     

Fear and Loathing on Reality Television: An Analysis of “America's Most Wanted” and “Unsolved Mysteries”*

From early newspapers to contemporary television drama, the media demonstrate a continuing fascination with crime. Two recent television programs, “America's Most Wanted” and “Unsolved Mysteries,” claim to offer a different treatment of crime in that these programs dramatize “real” crimes and encourage the television audience to assist in locating fugitives. Content analysis of the programs reveals that depictions of crime are consistent with television crime drama, and that these dramatizations resemble urban legends in which crime symbolizes the uncertainties of modern life. The programs convey an unpredictable world filled with unsafe people and places. This sense of modern danger justifies the programs' solicitation of audience participation through surveillance.

Service Learning in a Small Groups Course

This paper describes a service learning program used in a Sociology of Small Groups course. Service learning programs attempt to apply knowledge learned in the classroom in a setting of community service. This paper advocates the use of service learning as a tool for applying social knowledge even in courses that are not traditionally linked with service learning. The usefulness of a service learning program in a group processes course is identified. Details on the content of the program, the methods of evaluation and the relevance to the course material are provided. Numerous examples of how service learning can lead to classroom enhancement activities are described.     

Don't call it child abuse if It's really poverty

As a society, we continue to broaden the jurisdiction of child abuse programs so that an ever larger proportion of poor children (and their families) are drawn into the child protective system. Helping these families does not require mandatory reporting laws, involuntary investigations, central registers of reports, and psychologically oriented “treatment” interventions     

Status claims, performance expectations, and inequality in groups

We state and test two new theoretical assumptions regarding effects of explicit status claims upon others' performance expectations and the consequent group hierarchy: (1) that any such claim is aggregated with other status information, and (2) that the weight of the effect of a claim is a direct function of the status position of the person expressing it. Added to the core assumptions of theories of status generalization, the new assumptions account for phenomena also called “second-order expectations” and “status cues.” Results from a six-condition experimental test support the ideas, and permit comparing our assumptions with two variant mechanisms. We consider some uses of the extended theory, including interventions to control status effects within groups and legitimating and de-legitimating group hierarchies.     

Density of the quotient of non-negative quadratic forms in normal variables with application to the F-statistic

The density of the quotient of two non-negative quadratic forms in normal variables is considered. The covariance matrix of these variables is arbitrary. The result is useful in the study of the robustness of theF-test with respect to errors of the first and second kind. An explicit expression for this density is given in the form of a proper Riemann-integral on a finite interval, suitable for numerical calculation.
