Beyond demand–control: Emotional labour and symptoms of burnout in teachers

Abstract

Teaching is a profession that involves a high level of emotional labour. This includes such behaviours as surface acting (displaying an emotion that is not actually felt), deep acting (the activity undertaken to actually feel a required emotion), and suppression of emotion. In many professions, this emotional labour is thought to be related to high levels of burnout. The aim of our study was to show that emotional labour has a unique relationship with burnout that is separate from its relationship with the variables of the Demand Control Support (DCS) model. Emotional labour was studied, together with the variables of the Karasek Job Demand Control Support model, in a random sample of 365 mathematics teachers in the Netherlands. We used the Dutch Questionnaire on Emotional Labor (D-QEL) that measures: (1) surface acting, (2) deep acting, (3) suppression, and (4) emotional consonance. In line with other studies, job characteristics were found to be specifically related to emotional exhaustion. Surface acting was significantly related to depersonalization, and emotional consonance (the absence of emotional labour) was related to personal accomplishment. We conclude that whereas the DCS model has been valuable for understanding emotional exhaustion, emotional labour provides an additional perspective for understanding work stress.     

Selection of a Computerised Maintenance Management System: a case study in a regional health service

The selection of a Computerised Maintenance Management System (CMMS) is a strategic decision in any industry. In hospitals such systems are becoming increasingly necessary because of the high proportion of the budget allocated to the maintenance area and the increasing demand for quality from both health-care professionals and patients. The aim of this study is to propose a more satisfactory CMMS selection process. The process uses a decision-making model based on the use of the multicriteria technique ELECTRE II in two stages. First, the software suppliers that can guarantee a successful implementation of the CMMS are selected. Then, the CMMS that best meets the organisation's needs and requirements is selected. To demonstrate the process, the authors present a case study of the selection process in a Spanish regional health service. Finally, a discussion of the influence of the public health-care environment on the final decision is offered.     

Public-Private Partnership Contractual Design: A Computational Model of the Moral Hazard with Lotteries

Public-Private Partnership (PPP) is a new model of public management which consists of the contractual relationship between public and private entities. In particular, PPPs enable risk share between public and private sectors making the asymmetric information problem in a contractual arrangement more evident. The aim of this paper was to study a moral hazard problem applied to PPP contracts. To achieve this objective, a PPP computational contractual model including the moral hazard with lotteries was developed to assess how contractual changes could affect the optimum behavior of arrangement members. Simulations indicate that projects with higher economic value should attract more qualified firms, which may be why the companies expend more effort. To deal with possible contractual contingencies and try to minimize the moral hazard problem, the government could draw up more flexible contracts in order to include possible necessary changes and punish unwanted or improper consortium behavior.     

Chance-Corrected Measures of Reliability and Validity in 2 × 2 Tables

It is customary to use two groups of indices to evaluate a diagnostic method with a binary outcome: validity indices with a standard rater (sensitivity, specificity, and positive or negative predictive values) and reliability indices (positive, negative and overall agreements) without a standard rater. However neither of these classic indices is chance-corrected, and this may distort the analysis of the problem (especially in comparative studies). One way of chance-correcting these indices is by using the Delta model (an alternative to the Kappa model), but this means having to use a computer program to work out the calculations. This paper gives an asymptotic version of the Delta model, thus allowing simple expressions to be obtained for the estimator of each of the above-mentioned chance-corrected indices (as well as for its standard error).     

A Note on Unwanted Variance in Exploratory Factor Models

One strategy of exploratory factor analysis is to decide on the number of factors to extract by means of the eigenvalues of an initial principal component analysis. The present article proves that there is a non zero covariance of the factors with the components rejected when the number of factors to extract is determined by means of principal components analysis. Thus, some of the variance declared as irrelevant or unwanted in an initial principal component analysis is again part of the final factor model.     

Optimal correction for continuity in the chi-squared test in 2×2 tables

The most common asymptotic procedure for analyzing a 2 × 2 table (under the conditioning principle) is the ‰ chi-squared test with correction for continuity (c.f.c). According to the way this is applied, up to the present four methods have been obtained: one for one-tailed tests (Yates') and three for two-tailed tests (those of Mantel, Conover and Haber). In this paper two further methods are defined (one for each case), the 6 resulting methods are grouped in families, their individual behaviour studied and the optimal is selected. The conclusions are established on the assumption that the method studied is applied indiscriminately (without being subjected to validity conditions), and taking a basis of 400,000 tables (with the values of sample size n between 20 and 300 and exact P-values between 1% and 10%) and a criterion of evaluation based on the percentage of times in which the approximate P-value differs from the exact (Fisher's exact test) by an excessive amount. The optimal c.f.c. depends on n, on E (the minimum quantity expected) and on the error α to be used, but the rule of selection is not complicated and the new methods proposed are frequently selected. In the paper we also study what occurs when E ≥ 5, as well as whether the chi-squared by factor (n-1).     

Coefficients of determinations for variable selection in the msae regression

Our objective is to modify a robust coefficient of determination for the minimum sum of absolute errors MSAE regression proposed by McKean and Sievers (1987) so that it satisfies all the desirable properties. We also propose an adjusted coefficient of determination that is appropriate for comparing several models with different number of variables. Further, it has the property that if it decreases with the addition of predictor variables to the model, then the contribution of these variables is statistically non-significant. We illustrate the results with an example.     

Political Institutions,Elites, and Territorial Identity Formation in Belgium

Territorial identities in Belgium require a political rather than a cultural or structural explanation. The forces behind the development of identities in Flanders, Wallonia, Brussels and the German-speaking area are similar to the ones that produced the Belgian identity they are challenging. Political institutions and elites are at the heart of the process of territorial identity formation in Belgium. The emergence of Walloon and Flemish identities in the nineteenth and early twentieth centuries was the by-product of a struggle between the dominant French-speaking bourgeoisie and the traditional Flemish lower bourgeoisie within the institutional context of the early Belgian state. Transformations in the party system and reforms to political-territorial institutions in the last 40 years have strengthened these identities and created entirely new ones.
