Object-Oriented Bayesian Networks for Modeling the Respondent Measurement Error

In this article, Object-Oriented Bayesian Networks (OOBN) are proposed as a tool to model measurement errors in a categorical variable due to respondent. A mixed measurement error model is presented and an OOBN implementing such a model is introduced. The insertion of evidence represented by the observed value and its propagation throughout the network yields for each unit the probability distribution of the true value given the observed. Two methods are used to predict the individual true value and their performance is evaluated via simulation.     

A practical approach for assessing the effect of grouping in hierarchical spatio-temporal models

Hierarchical spatio-temporal models allow for the consideration and estimation of many sources of variability. A general spatio-temporal model can be written as the sum of a spatio-temporal trend and a spatio-temporal random effect. When spatial locations are considered to be homogeneous with respect to some exogenous features, the groups of locations may share a common spatial domain. Differences between groups can be highlighted both in the large-scale, spatio-temporal component and in the spatio-temporal dependence structure. When these differences are not included in the model specification, model performance and spatio-temporal predictions may be weak. This paper proposes a method for evaluating and comparing models that progressively include group differences. Hierarchical modeling under a Bayesian perspective is followed, allowing flexible models and the statistical assessment of results based on posterior predictive distributions. This procedure is applied to tropospheric ozone data in the Italian Emilia–Romagna region for 2001, where 30 monitoring sites are classified according to environmental laws into two groups by their relative position with respect to traffic emissions.     

Occupational stress and cardiovascular reactivity in blue-collar workers

This study analyses the influence of chronic occupational stress on cardiovascular reactivity (heart rate [HR] and blood pressure [BP] elevation from baseline to maximal challenge) during a standard mental stress test (modified version of the STROOP colour word interference test). The test was applied to a sample of 190 healthy male blue-collar workers at the end of a regular working day. Our research hypothesis was based on the assumption that sustained autonomic activation due to chronic occupational stress may reduce cardiovascular responsiveness to challenge: workers defined by high level of chronic occupational stress exhibited lower maximal HR and BP elevations under challenge as compared to workers with low levels of stress. Three distinct indicators of occupational stress were derived from structured interviews: 'cumulative workload', 'worsening of job conditions', and 'high demand and low job security'. Statistical analysis, using ANOVA, showed that all main effects of chronic stress were in the expected direction (6 of 9 effects were statistically significant at the 0'05 level). These effects remained stable after adjusting for age, hypertensive status, physiological baseline level, cigarette smoking, test performance, and individual style of coping. In summary, cardiovascular reactivity under experimental challenge is modulated by an individual's experience of chronic occupational stress.     

Mikropolitisches Kompetenzmodell

The acquirement of and possessing competencies is a fundamental requirement to every executive. Micro-political competence constitutes uncharted waters. Therefore in the research project “Micro-politics and women’s career advancement competence” were, with regard to the category gender, pursued the question, whether micro-political competence are acquirable with the help of coaching, and whether it is beneficial for women’s career advancement. The outcome is the Micro-political Competence Model (MCM), which is the main topic of this paper. After an introduction in the study, the MKM is to be described theoretically and the four competence classes of Micro-political Competence will be defined. In the final empirical part benefit and practicability of the Model will be demonstrated, using the example of case studies.     

Is there such a thing as a family constitution? A test based on credit rationing

The paper tests the hypothesis that private transfers can be explained by the existence of self-enforcing family constitutions prescribing the minimum level at which a person in middle life should support her young children and elderly parents. The test is based on the effect of a binding credit ration on the probability of making a money transfer, which can be positive only in the presence of family constitutions. Allowing for the possible endogeneity of the credit ration, we find that rationing has a positive effect on the probability of giving money if the potential giver is under the age of retirement, but no significant effect if the person is already retired. This appears to reject the hypothesis that transfer behavior is the outcome of unfettered individual optimization on the part of either altruistic or exchange motivated agents, but not the one that individuals optimize subject to a self-enforcing family constitution. The policy implications are briefly discussed.

Ambivalent sexism and egalitarian ideology in perception of psychological abuse and (in)vulnerability to violence / Sexismo ambivalente e ideología igualitaria en la percepción del maltrato psicológico y la (in)vulnerabilidad a la violencia

Abstract

Psychological violence against women in intimate relations is one of the most widespread and hidden ways of limiting their human rights. Nowadays different ideologies, including sexism and feminism, can contribute to (dis)regard this phenomenon. This study focuses on the relationship between ambivalent sexism (in its hostile and benevolent dimensions) and feminism (in the egalitarian ideology dimension) with the identification of psychological violence and the perception of invulnerability to the intimate partner violence in women. The mediator role of the myths about gender-based violence in these relationships is analysed. Participants were 91 women, with heterogeneous socio-demographic characteristics. Results showed benevolent sexism as a risk factor and egalitarian feminism ideology as a protector factor in the process of the perception of psychological violence. The egalitarian feminism ideology also appears as the main predictor of the perception of invulnerability to abuse. This relationship is mediated by the degree of adhesion to the myths about gender-based violence. These findings reinforce the importance of the attitudinal and ideological factors in the perception of gender-based violence.     

Building resilient communities: Social work practice and rural Queensland

Abstract

This paper applies the notion of community resiliency to rural and regional Queensland and explores the role of human services and practitioners in developing this resiliency. Communities can be considered as being ‘resilient’ when they respond to crises in ways that strengthen communal bonds, resources and the community's capacity to cope. Increasingly, community resiliency has become the focus of international research (Kulig and Brown 1996; 1997), In our work, we have been exploring alliance-building between practitioners and their communities in several research projects in rural and regional Queensland. We argue that these alliances contribute significantly to the building of resiliency and are a potential site for further work in strengthening and sustaining rural communities. The implications of community resiliency for social work practice are discussed.
