Background: The pervasiveness of smartphones has raised concerns about an increase in the prevalence of problematic smartphone use (PSU), which depends on a set of psychological and behavioral risk factors. Previous research has yielded mixed results on factors predicting PSU, including social anxiety and trust. In particular, the role of trust remained largely unexplored. In the present study,...

Press ombudsmen are particularly visible in Anglo-Saxon countries and in Sweden, but they are also present in most European and Latin American countries. Many studies have been conducted to understand the origins, the role and the effectiveness of Anglo-Saxon ombudsmen but not much was known about ombudsmen active in the rest of the world. On the occasion of the function's 40th anniversary - the...

This paper combines causal mediation analysis with double machine learning to control for observed confounders in a data-driven way under a selection-on- observables assumption in a high-dimensional setting. We consider the average indirect effect of a binary treatment operating through an intermediate variable (or mediator) on the causal path between the treatment and the outcome, as well as...

This paper sets out to analyze the role that argumentation may play in dispute resolution, in particular within the practice of dispute mediation. The focus is on the complex interplay of different argumentative discussions which are necessary for the parties to personally handle and possibly solve their conflict. This contribution focuses in particular on the mediator's role in a...

This work investigates how argumentation, namely the communicative exchange aimed at founding ones position in a reasonable fashion, is an essential condition for the fulfilment of the pragmatic goals of mediation, conceived of as a conflict resolution practice. In mediation, the parties are competent and responsible for the decision on the conflict, while the mediator helps them assume an...

This paper proposes semi- and nonparametric methods for disentangling the total causal effect of a continuous treatment on an outcome variable into its natural direct effect and the indirect effect that operates through one or several intermediate variables or mediators. Our approach is based on weighting observations by the inverse of two versions of the generalized propensity score (GPS),...

This paper investigates the sensitivity of average wage gap decompositions to methods resting on different assumptions regarding endogeneity of observed characteristics, sample selection into employment, and estimators’ functional form. Applying five distinct decomposition techniques to estimate the gender wage gap in the U.S. using data from the National Longitudinal Survey of Youth 1979,...

The decomposition of gender or ethnic wage gaps into explained and unexplained components (often with the aim to assess labor market discrimination) has been a major research agenda in empirical labor economics. This article demonstrates that conventional decompositions, no matter whether linear or nonparametric, are equivalent to assuming a (probably too) simple model of mediation (aimed at...

Mediation analysis aims at evaluating the causal mechanisms through which a treatment or intervention affects an outcome of interest. The goal is to disentangle the total treatment effect into an indirect effect operating through one or several observed intermediate variables, the so-called mediators, as well as a direct effect reflecting any impact not captured by the observed mediator(s)....
