Balancing fit and parsimony to improve Q-matrix validation

The Q-matrix identifies the subset of attributes measured by each item in the cognitive diagnosis modelling framework. Usually constructed by domain experts, the Q-matrix might contain some misspecifications, disrupting classification accuracy. Empirical Q-matrix validation methods such as the general discrimination index (GDI) and Wald have shown promising results in addressing this problem. However, a cut-off point is used in both methods, which might be suboptimal. To address this limitation, the Hull method is proposed and evaluated in the present study. This method aims to find the optimal balance between fit and parsimony, and it is flexible enough to be used either with a measure of item discrimination (the proportion of variance accounted for, PVAF) or a coefficient of determination (pseudo-R²). Results from a simulation study showed that the Hull method consistently showed the best performance and shortest computation time, especially when used with the PVAF. The Wald method also performed very well overall, while the GDI method obtained poor results when the number of attributes was high. The absence of a cut-off point provides greater flexibility to the Hull method, and it places it as a comprehensive solution to the Q-matrix specification problem in applied settings. This proposal is illustrated using real data.     

Utopias and Comparative Assessments of Justice

When we make public policy choices, is it helpful to know how utopia (that is, the perfectly just institutional design) would look? Amartya Sen argues that it is neither necessary, nor sufficient, nor even contributory. He claims that before making a policy choice one should compare several feasible institutional designs to see which promotes justice most (a “comparative assessment” of justice), and that it is misleading to use the perfect design as a standard in those comparisons. Principles of justice are the proper standard. The present article contends that the perfect design has nevertheless an important role to play in the prior task of identifying and refining our principles of justice. It also shows that the perfect design—in at least one sense of this term—may be a legitimate long‐term goal for present policy choices.     

Measurement Invariance of the Day Reconstruction Method: Results from the COURAGE in Europe Project

Given the growing interest in the study of subjective well-being as a measure of social progress, instruments that produce valid and reliable scores and that can be used within and across countries are needed. The aim of the present study was to analyze the measurement equivalence of the Day Reconstruction Method in its brief version, using nationally representative samples from Finland, Poland, and Spain obtained within the COURAGE in Europe project. The goodness-of-fit of a two-correlated-factors model and the reliability of the scores obtained were assessed. Cross-country invariance was tested employing a multiple group confirmatory factor analysis, through sequential constraint imposition. In each country, measurement invariance was tested across time frames (morning, afternoon and evening) and days of the week (weekday and weekend). The results found support for the hypothesis of a two-correlated-factors (positive and negative affect) structure; the reliability of the positive, the negative and the net affect scores showed appropriate values. A high equivalence across the three national samples was found: all items except one showed strong measurement invariance indicating that respondents from Finland, Poland, and Spain attribute the same meaning to the latent construct under study, and the levels of the underlying items are equal in all three countries. Similar results were found for the measurement equivalence across time frames and days of the week. Our findings support the assumption of comparability across the different samples considered; in general, higher positive affect and lower negative affect were found in Finland, in the evening and at the weekend.     

Wellbeing at Work and the Great Recession: The Effect of Others’ Unemployment

The recent recession has generated a tremendous increase in unemployment rates in Spain. In this paper we use a very rich repeated cross-section dataset on workers’ job conditions, together with regional unemployment rates, to investigate whether peers’ unemployment affects individuals’ job satisfaction. We find that, once perceived job stability is controlled for, peers’ unemployment shows a positive effect on individuals’ wellbeing at work, greater and more precisely estimated for men and private-sector workers. The impact is highly non-linear and the greatest effect is found for unemployment rates exceeding 10 %. Interestingly, the results are robust to controlling for workforce selection.     

Subjective Wellbeing and Income: Empirical Patterns in the Rural Developing World

A commonality in the economics of happiness literature is that absolute income matters more for the subjective wellbeing of people at low income levels. In this article, we use a large sample of people in rural areas of developing countries with relatively low income levels to test whether subjective wellbeing an increasing function of absolute income in our sample, and to analyze the existence of adaptation and social comparison effects on subjective wellbeing. Our sample includes 6,973 rural households in 23 countries throughout Asia, Africa, and Latin America. The average total income per adult equivalent in our sample was US$ 1555, whereas levels of subjective wellbeing resembled levels found in previous research using cross-country data. We find that, despite low levels of absolute income, levels of subjective wellbeing of our respondents resemble levels found in previous research using cross-country data. We also find remarkable similarities in many of the determinants of subjective wellbeing previously tested. Our data show that absolute income covariates with subjective wellbeing, but—as for richer samples—the magnitude of the association is lower once we control for adaptation and social comparison. Finally, our results suggest that social comparison has a stronger effect than adaptation in explaining the subjective wellbeing of our sample. Our findings highlight the importance of adaptation and social comparison even at low levels of absolute income.     

Hermeneutics and Sport

Hermeneutics is the exploration of the process of textual interpretation. As such, it has long been recognised as an important component within the humanities and social sciences, whether one deals with actual texts or with other the products of meaningful human activity, including social actions and utterances. Here, we offer a brief overview of the contribution that hermeneutics might make to the philosophy of sport. If sports and sporting events are seen to be the results of meaningful human interactions, then they are meaningful phenomena that lend themselves to interpretation. It can thus be argued that a hermeneutics of sport is a valid and important discipline, worthy of consideration and development. We offer a review of the nature and history of hermeneutics in general, briefly exploring the place of key figures such as Schleiermacher, Heidegger, Gadamer and Riceour, as well as key concepts such as that of the hermeneutic circle. In addition, we suggest the importance of a hermeneutics of suspicion, grounded in the work of Marx, Freud and Nietzsche. In the second part of our introduction, we briefly comment on each of the papers that comprise the current volume, and that reflect the diversity of approaches that a hermeneutics of sport might embrace.     

Mobbing: a meta-analysis and integrative model of its antecedents and consequences

Although mobbing has been extensively studied, empirical research has not led to firm conclusions regarding its antecedents and consequences, both at personal and organizational levels. An extensive literature search yielded 86 empirical studies with 93 samples. The matrix correlation obtained through meta-analytic techniques was used to test a structural equation model. Results supported hypotheses regarding organizational environmental factors as main predictors of mobbing.     

Toward a richer view of the scientific method. The role of conceptual analysis

Within the complex set of activities that comprise the scientific method, three clusters of activities can be recognized: experimentation, mathematization, and conceptual analysis. In psychology, the first two of these clusters are well-known and valued, but the third seems less known and valued. The authors show the value of these three clusters of scientific method activities in the works of the quintessential scientist Galileo Galilei. They then illustrate how conceptual analysis can be used in psychology to clarify the grammar and meaning of concepts, expose conceptual problems in models, reveal unacknowledged assumptions and steps in arguments, and evaluate the consistency of theoretical accounts. The article concludes with a discussion of three criticisms of conceptual analysis.     

Impact of perceived value on casual mobile game loyalty: The moderating effect of intensity of playing

The retention rate of mobile game players is one of the subjects that spark most interest in the industry, as many abandon the games only a few hours after downloading them. This study examines the antecedents of loyalty towards mobile games from the perspective of perceived value and explores the moderating effect of intensity of playing. The results revealed that hedonic value (i.e., perceived enjoyment and perceived attractiveness) and, to a lesser extent, utilitarian value (i.e., effort expectancy and perceived usefulness) are crucial in the loyalty that players feel towards mobile games. Intensity of playing weakens the relationship between perceived usefulness, perceived enjoyment and loyalty intention. Based on the findings, theoretical and practical implications are provided.     

Sabina Spielrein: From Being a Psychiatric Patient to Becoming an Analyst Herself

In this paper, I evaluate Sabina Spielrein’s life and ideas from a contemporary understanding. I do this by considering the context and situation in which she lived: a journey from being a hospitalized psychiatric patient to becoming a psychoanalyst herself. From her crucial life experiences she learned that the main psychic conflicts stem from the struggle between life and death, and not from opposing ego drives and sexual desires. Spielrein’s considerable creative potentials were nurtured, as well as blocked by her inner conflicts, but also by the enormous historical conflicts of her time.
