Understanding selection bias,time-lags and measurement bias in secondary data sources: Putting the Encyclopedia of Associations database in broader context

Secondary data gathered for purposes other than research play an important role in the social sciences. A recent data release has made an important source of publicly available data on associational interests, the Encyclopedia of Associations (EA), readily accessible to scholars (www.policyagendas.org). In this paper we introduce these new data and systematically investigate issues of lag between events and subsequent reporting in the EA, as these have important but under-appreciated effects on time-series statistical models. We further analyze the accuracy and coverage of the database in numerous ways. Our study serves as a guide to potential users of this database, but we also reflect upon a number of issues that should concern all researchers who use secondary data such as newspaper records, IRS reports and FBI Uniform Crime Reports.     

From Customer‐Oriented Strategy to Organizational Financial Performance: The Role of Human Resource Management and Customer‐Linking Capability

Drawing on the organizational capabilities literature, the authors developed and tested a model of how supportive human resource management (HRM) improved firms’ financial performance perceived by marketing managers through fostering the implementation of a customer‐oriented strategy. Customer‐linking capability, which is the capability in managing close customer relationships, indicated the implementation of the customer‐oriented strategy. Data collected from two emerging economies – China and Hungary – established that supportive HRM partially mediated the relationship between customer‐oriented strategy and customer‐linking capability. Customer‐linking capability further explained how supportive HRM contributed to perceived financial performance. This study explicates the implication of customer‐oriented strategy for HRM and reveals the importance of HRM in strategy implementation. It also sheds some light on the ‘black box’ between HRM and performance. While making important contributions to the field of strategy, HRM and marketing, this study also offers useful practical implications.     

Does change process healthiness reduce the negative effects of organizational change on the psychosocial work environment?

Abstract

This study aimed to investigate whether the detrimental effects of organizational change on the psychosocial work environment are reduced by the “healthiness” of change processes. This includes the management's awareness that the change may be experienced differently by various individuals and groups (diversity); availability of the manager during the process; the degree to which conflicts are resolved constructively; and the degree to which the new roles to be taken on are clarified. Two studies are presented. Using a randomized sample of the Norwegian working population (N = 2389), the first study showed that there were both direct and indirect positive relationships between organizational change and stress, with job demands (but not control and support) as a mediator. In the second study a healthy change process index (HCPI) was developed from dimensions of healthy change that had emerged in an earlier qualitative study. Using data from seven Norwegian enterprises undergoing change (N = 561), this study showed that the healthiness of the change process was related negatively to stress and positively to Control and Support, but not to Demands. Overall, these findings support the idea that a healthy process may not reduce the additional demands produced by organizational change. However, a healthy process may still be able to reduce the experience of stress and facilitate coping with stress and associated increased demands through enhancing the psychosocial work environment.     

EDUCATION AND MOBILITY

We show that the length of compulsory education has a causal impact on regional labor mobility. We reach this conclusion from an analysis of a quasi‐exogenous staged Norwegian school reform, using register data on the whole population. Based on the results, we conclude that part of the US–Europe difference, as well as the European North–South difference in labor mobility, is likely to be due to differences in levels of education in the respective regions.     

To Pool or Not to Pool in Call Centers

Should service capacities (such as agent groups in call centers) be pooled or not? This paper will show that there is no single answer. For the simple but generic situation of two (strictly pooled or unpooled) server groups, it will provide (1) insights and approximate formulae, (2) numerical support, and (3) general conclusions for the waiting‐time effect of pooling. For a single call type, this effect is clearly positive, as represented by a pooling factor. With multiple job types, however, the effect is determined by both a pooling and a mix factor. Due to the mix factor, this effect might even be negative. In this case, it is also numerically illustrated that an improvement of both the unpooled and the strictly pooled scenario can be achieved by simple overflow or threshold scenarios. The results are of both practical and theoretical interest: practical for awareness of this negative effect, the numerical orders, and practical scenarios in call centers, and theoretical for further research in more complex situations.     

The Trace Restriction: An Alternative Identification Strategy for the Bayesian Multinomial Probit Model

Previous authors have made Bayesian multinomial probit models identifiable by fixing a parameter on the main diagonal of the covariance matrix. The choice of which element one fixes can influence posterior predictions. Thus, we propose restricting the trace of the covariance matrix, which we achieve without computational penalty. This permits a prior that is symmetric to permutations of the nonbase outcome categories. We find in real and simulated consumer choice datasets that the trace-restricted model is less prone to making extreme predictions. Further, the trace restriction can provide stronger identification, yielding marginal posterior distributions that are more easily interpreted.     

Participation of youth in decision‐making procedures during residential care: A narrative review

Participation in decision‐making procedures of young people in care is considered a key element that affects their current or future living circumstances and might improve the quality of decision‐making on and delivery of provided services. This narrative literature review, covering the period 2000–2016, focuses on the opportunities of young people to participate, the challenges and facilitators to participation, and the outcomes of care related to participation. Sixteen studies met our search criteria. Several studies show that young people seem to have limited possibilities to “meaningful” participation in decision‐making. Various challenges and facilitators in the participation process emerge with regard to the level of the young person, the professional, and the (sociocultural) context. None of the studies provides evidence for a connection between the “amount” of youth participation in decision‐making and/or treatment during the care process and the outcomes of residential care. Implications for research and practice are reflected upon.     

Group variable selection in cardiopulmonary cerebral resuscitation data for veterinary patients

Cardiopulmonary cerebral resuscitation (CPCR) is a procedure to restore spontaneous circulation in patients with cardiopulmonary arrest (CPA). While animals with CPA generally have a lower success rate of CPCR than people do, CPCR studies in veterinary patients have been limited. In this paper, we construct a model for predicting success or failure of CPCR, and identifying and evaluating factors that affect the success of CPCR in veterinary patients. Due to reparametrization using multiple dummy variables or close proximity in nature, many variables in the data form groups, and thus a desirable method should take this grouping feature into account in variable selection. To accomplish these goals, we propose an adaptive group bridge method for a logistic regression model. The performance of the proposed method is evaluated under different simulated setups and compared with several other regression methods. Using the logistic group bridge model, we analyze data from a CPCR study for veterinary patients and discuss their implications on the practice of veterinary medicine.     

Movers and Stayers: A Study of Emigration from Sweden 1993–2014

A standard proposition in the migration literature is that emigrants are not drawn randomly from their source population, but rather compose a self-selected group in terms of labour market characteristics. Such self-selection refers to observed characteristics, such as education, or occupation, as well as unobserved characteristics such as cognitive abilities. However, due to data limitations, most previous studies on selectivity have analysed immigrants’ characteristics at destinations rather than using data from their source countries. This paper assesses emigrants’ selectivity patterns by following the full-risk population of natives over a long period of time (over 20 years). It also includes an innovative measure of selectivity on unobserved characteristics—namely, school performance—as a proxy for individual motivation and cognitive abilities, and it compares it to the widely used measure of income residuals. We use Swedish register data and assess the probabilities of leaving Sweden between 1993 and 2014 among men and women born in Sweden between 1975 and 1978. We further look for differences among Swedish emigrants who chose different countries of destination. The findings suggest that emigrants are positively self-selected in terms of their observed characteristics, whereas selectivity patterns in terms of unobserved characteristics are more complex. When we assess unobservable characteristics using compulsory school grades as a proxy, emigrants are found to be positively self-selected, while when using income residuals, we find that the effect is U-shaped. Individuals leaving to non-Nordic countries are also found to be more positively self-selected than those heading to neighbouring countries. We discuss these findings and their implications in light of economic and sociological theories.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10680-022-09634-3.     

Health-Related Quality of Life Among Abused Women One Year After Leaving a Violent Partner

This is the first follow up study measuring quality of life among abused women who have left their abusive partner. The women (n = 22) answered a questionnaire while staying at women’s shelter and one year later. The aim was to examine long-term effects of intimate partner violence against women on health-related quality of life. Health-related quality of life was measured using the SF-36 Health Survey and the WHOQOL-BREF. The meantime for living in a violent partnership was 11 years, most of the women had children under 10 years living with them, low income and were on sickness absence or disability pension. About half of the women had experienced threats of violence and 6 had experienced violent acts after leaving their partner. SF-36 scores after one year were significantly better in vitality (t-test, P < 0.001), mental health (t-test P < 0.001) and social domains (t-test, P < 0.04). WHOQOL-BREF scores did not change significantly from baseline, showing that the SF-36 showed more responsiveness in this population. Regression analysis showed that serious physical violence reported at baseline predicted significantly less improvement in physical and mental health and role-emotional in the SF-36 and in social relationships and environmental health in the WHOQOL-BREF. High psychological violence at baseline predicted significantly less improvement in mental health in the SF-36 and in social relationships and environmental health in the WHOQOL-BREF.
