Merging information for semiparametric density estimation

Summary.  The density ratio model specifies that the likelihood ratio of m −1 probability density functions with respect to the m th is of known parametric form without reference to any parametric model. We study the semiparametric inference problem that is related to the density ratio model by appealing to the methodology of empirical likelihood. The combined data from all the samples leads to more efficient kernel density estimators for the unknown distributions. We adopt variants of well-established techniques to choose the smoothing parameter for the density estimators proposed.     

Geographic labour mobility and unemployment insurance in Europe

Conventional wisdom suggests that the generous provision of UI in Europe can account for the low regional mobility rates. Emphasizing the disincentive effect, this hypothesis ignores that UI might also have a positive effect by relaxing liquidity constraints in the presence of mobility and search costs. This paper investigates empirically the effect of UI on geographic labour mobility for five European countries. Overall, the findings suggest that receiving benefits is not associated with lower mobility, and they indicate that the effects might vary depending on the institutional characteristics and the incentive structure of the UI system of each country.      

An emerging transnational industrial relations? Exploring the prospects for cross‐border labour bargaining

Global union federations (GUFs) and multinational enterprises (MNEs) have been concluding “international framework agreements” (IFAs) to protect their interests amidst the globalizing economic landscape. By modelling the underlying bargaining processes, the authors show that IFAs can be expected when both sides exhibit risk aversion, although the agreement will favour the less risk‐averse side. Since globalization has created fewer vulnerabilities for MNEs than for GUFs, IFAs have so far typically delivered only minimal benefits for labour. But this should change in the future if strengthened transnational union capacities and abilities to threaten MNEs with reputational costs bring greater equalization of attitudes towards risk.     

Judging Facial Emotion Expressions in Context: The Influence of Culture and Self-Construal Orientation

We assessed the impact of social context on the judgment of emotional facial expressions as a function of self-construal and decoding rules. German and Greek participants rated spontaneous emotional faces shown either alone or surrounded by other faces with congruent or incongruent facial expressions. Greek participants were higher in interdependence than German participants. In line with cultural decoding rules, Greek participants rated anger expressions less intensely and sad and disgust expressions more intensely. Social context affected the ratings by both groups in different ways. In the more interdependent culture (Greece) participants perceived anger least intensely when the group showed neutral expressions, whereas sadness expressions were rated as most intense in the absence of social context. In the independent culture (Germany) a group context (others expressing anger or happiness) additionally amplified the perception of angry and happy expressions. In line with the notion that these effects are mediated by more holistic processing linked to higher interdependence, this difference disappeared when we controlled for interdependence on the individual level. The findings confirm the usefulness of considering both country level and individual level factors when studying cultural differences.     

Gender differences in life expectancy at birth in Greece 1994–2017

In this paper, we analyse the difference in life expectancy at birth between females and males in the Greek population between the years 1994–2017. After constructing life tables per gender, we used the method of Arriaga in order to decompose life expectancy’s differences by age and sex. We found that the gender gap increased until 2009 and decreased afterwards. Moreover, we estimated the differential contribution of the broad age groups of the population to the regulation of gender inequalities in longevity and studied the different effect of the causes of death. Besides age, the most important regulators are the neoplasms and the diseases of the circulatory system, followed by the external causes of morbidity and mortality, as well as the diseases of the respiratory system. All other causes of death play a marginal role. The results of the analysis indicate the need for the development and expansion of several public interventions and programs in order, not only to reduce the gender inequalities in longevity, but also to reduce the prevalence of several preventable diseases in the population.

     

Adolescent Online Gambling in Cyprus: Associated School Performance and Psychopathology

This paper presents results from the study of gambling behaviors in a representative sample of Cypriot high-school students. The aim of the study was to ascertain epidemiology of adolescent online gambling in Cyprus and possible correlates. The sample consisted of 2,684 students (48.5 % boys, 51.5 % girls) from the first grades of junior (Gymnasium) and senior (Lyceum) high school. Our results indicate that gamblers presented with lower school achievement and related expectations while scoring consistently higher on measures of Internet addiction, parental bonding and psychopathology. Discriminant analysis revealed two profiles which explained the most variance in gambling behavior; the first profile that corresponded to more explained variance was the student with higher psychopathology, less prosocial behavior, higher Internet addiction score with higher frequencies of online activities and moderate levels of truancy and lower expectation of school achievement. The second profile was that of a student who reported less psychopathology, more prosocial behavior, less involvement with the Internet in general but skipped classes more and his prospects on finishing high school were even slimmer. These results will be utilized in the design of a comprehensive prevention program in an effort to combat online addictive behaviors.

A synaptic common sense? McLuhan’s tactility and electronic media rhythms

In Understanding Media, Marshall McLuhen proposed that tactility would eventually become a determining factor in electronic media, leading to the formation of a new kind of “common sense.” This article investigates whether by exploring this idea we are able to arrive at an alternative theoretical framework for understanding tactility, a framework that avoids the tactile-optic distinction and the understanding of tactility as a sensation primarily innervated through the bodily part of the hand. McLuhan’s notions of “acoustic space” and “contraction” are directly related to this breakthrough. It is further argued that the resulting theoretical framework can be enriched when considered in conjunction with social analyses of rhythms and used to account for the differentiation and customization or individualization of media use in the digital age. In this way, tactility is treated as embedded within rhythmic signals and fluctuations in media, allowing us to rethink McLuhan’s “common sense” in a singularly illuminating way.     

Effects of Activated and Dispositional Self-Construal on Emotion Decoding Accuracy

The present study examined effects of temporarily salient and chronic self-construal on decoding accuracy for positive and negative facial expressions of emotion. We primed independent and interdependent self-construal in a sample of participants who then rated the emotion expressions of a central character (target) in a cartoon showing a happy, sad, angry, or neutral facial expression in a group setting. Primed interdependence was associated with lower recognition accuracy for negative emotion expressions. Primed and chronic self-construal interacted such that for interdependence primed participants, higher chronic interdependence was associated with lower decoding accuracy for negative emotion expressions. Chronic independent self-construal was associated with higher decoding accuracy for negative emotion. These findings add to an increasing literature that highlights the significance of perceivers’ socio-cultural factors, self-construal in particular, for emotion perception.
