We examine the complex relationship between money and happiness. We find that both permanent income and wealth are better predictors of life satisfaction than current income and wealth. They matter not only in absolute terms but also in comparative terms. However, their relative impacts differ. The first exerts a comparison effect – the higher the permanent income of the reference group, the lower life satisfaction – the second exerts an information effect – the higher the permanent wealth of the reference group, the higher life satisfaction. We also show that negative transitory shocks to income reduce life satisfaction while transitory shocks to wealth have no effect. Lastly, we analyse the effects of their components and find that not all of them predict life satisfaction: permanent taxes do not matter, while only the value of permanent real estate, financial and business assets do. Finally, we use quantile regression and analyse to what extent our results vary along the well-being distribution, finding the impacts to be larger at lower levels of life satisfaction. [less ▲]

We study the effects of Chapter 11 bankruptcy protection on competitive product pricing in both domestic and international markets using data from the airline industry. We find a decline of about 5% in domestic markets and an even more significant drop in international markets. Further, in international markets the competing carriers respond by dropping their prices as well, whereas they slightly increase them domestically. By contrast, existing literature considers only domestic markets finding a more moderate fare drop of about 3% in domestic markets by the bankrupt carrier, with mixed results on the fare drop by competitors.

Dieses Kapitel geht der Frage nach, ob Lehrerüberzeugungen und –erwartungen, je nach sonderpädagogischem Förderbedarf variieren. Außerdem wurde deren Einfluss sowohl auf die Gefühle bei Auseinandersetzung mit der Inklusion von unterschiedlichen Schüler*innen, als auch auf die persönliche Bereitschaft Inklusion umzusetzen, untersucht. Die Studien basieren einerseits auf dem Dualen Prozessmodel der sozialen Kognition und betrachten andererseits das Stereotype-Content-Modell, laut dem Wärme und Kompetenz über 80% der Unterschiedlichkeiten in der Personenwahrnehmung erklären. Die Ergebnisse zeigten, dass Überzeugungen und Erwartungen von dem Typ von Förderbedarf beeinflusst werden. Positivere Überzeugungen bezüglich der Schülermerkmale (Wärme und Kompetenz) und höhere Leistungserwartungen waren hierbei mit positiveren Gefühlen und einer stärker ausgeprägten persönlichen Bereitschaft, die Schüler*innen mit sonderpädagogischem Förderbedarf zu inkludieren, verbunden. Abschließend werden die daraus resultierenden Konsequenzen für die Lehreraus- und -weiterbildung abgeleitet und diskutiert. [less ▲]

Die Auffassung, dass Grenzen aus sozialer Praxis hervorgehen und soziale Praxis hervorbringen, hat in den letzten Jahrzehnten für eine Reihe an Ansätzen und Begriffen gesorgt. Der Beitrag versucht diese zu systematisieren und stellt einen processual shift, multiplicity shift und complexitiy shift vor. Diese Trends beschreiben verschiedene analytische Schwerpunktsetzungen und eine zunehmend differenziertere Beschäftigung mit Grenzen.

In verschiedenen europäischen Ländern führt der Wechsel zur Sekundarschule zu einer bedeutsamen Aufgliederung der Bildungswege, welche ein unterschiedlich hohes Schulleistungsniveau der Schüler*innen voraussetzen. Die Akkuratheit der Zuweisung von Sekundarschulformen bestimmt nicht nur die Optionen der Schüler*innen bei späteren Übergangen im Bildungssystem, sondern beeinflusst auch den weiteren beruflichen und persönlichen Werdegang der Schüler*innen. Schüler*innen mit Migrationshintergrund sind auf die höheren sekundären Schulformen unterrepräsentiert. Inwiefern diese Unterrepräsentation auf stereotypgeprägte Leistungserwartungen zurückzuführen ist, ist bis jetzt unklar, denn es lisgt kein Kriterium vor, um die Urteilsakkuratheit adäquat zu messen. In diesem Kapitel wird ein Ansatz beschrieben, ein solches Akkuratheitskriterium zu entwickeln und zu validieren. In einem zweiten Schritt wird das Kriterium angewendet, um den Zusammenhang zwischen stereotypgeprägten Erwartungen und der Akkuratheit der Übergangsentscheidungen zu untersuchen. Das Kriterium erweist sich als valides Maß und könnte so einen wertvollen Ansatz für weitere Untersuchungen der Akkuratheit von Lehrerurteilen darstellen. Obwohl Lehrer*innen im Allgemeinen eine hohe Urteilsakkuratheit aufweisen, bestätigen die Befunde dennoch die Zusammenhänge zwischen stereotypgeprägten Erwartungen und Urteilsverzerrungen. [less ▲]

Objective: Criterion A of the alternative model for the classification of personality disorders in the DSM-5 introduced the Level of Personality Functioning Scale (LPFS), a dimensional model for the assessment of impairments in self and interpersonal functioning. The LPFS was developed based on a review of different measures of personality functioning, such as the Reflective Functioning Scale, a measure of mentalizing. This study investigated the empirical overlap between LPFS and mentalization. Methods: The study sample included adult inpatients (n = 55) with a mental disorder and a healthy adult control group (n = 55). All participants were examined regarding the LPFS using the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1); mentalizing was assessed with the Brief Reflective Functioning Interview and coded with the Reflective Functioning Scale. We used structural equation modeling to investigate the relationship between LPFS domains and mentalization. Correlation analysis was used to examine the agreement between interview-rated LPFS and self-report measures of personality dysfunction. Results: All domains of the LPFS were significantly related to mentalizing. Interview-rated LPFS was significantly associated with self-reported personality dysfunction. Conclusion: The findings support the notion that the LPFS and mentalization share a strong conceptual and operational overlap by demonstrating that both constructs are empirically interrelated. The results yield further support for the validity of the LPFS as a dimensional model for the assessment of personality disorder severity. [less ▲]

Task orientation is currently a prominent concept under discussion in primary school di-dactics. It focuses on tasks along which pupils acquire competences on distinct levels of compe-tence. The qualitative empirical study ANONYMOUS pursues the question which conception of task orientation is present in current textbooks in primary science education. The study follows two foci: (i) the introduction of a new category system for the analysis of the task-orientation potential of tasks, based on the further development of existing category systems for analyzing tasks; and (ii) the analysis of 994 task statements in science textbooks with respect to the di-dactic quality of their task orientation. The sample included nine primary science textbooks, four from Germany and five from Luxembourg. Textbooks were selected from the most fre-quently sold series in the respective country. All tasks of the textbooks were analyzed deduc-tively and inductively by four coders in three steps: (i) identifying tasks with task-oriented po-tential; (ii) itemizing different types of task-orientation potential; and (iii) comparing the text-books with respect to country- and period-specific manifestations of task orientation. Analysis indicated that (i) there are few tasks which meet the criteria of task orientation; (ii) distinct types of task orientation can be generated, among which implicit forms dominate; and (iii) dif-ferences occur in the characteristics of task orientation between older and newer textbooks as well as between German and Luxembourgish ones. Central points of discussion ensue from this: the need to develop models for social and cognitive activation for tasks, challenges for school management and professional development for teachers, and support for pupils—in particular high achieving heterogenization.

Early life adversity (ELA) may cause permanent disturbances in brain-body signaling. These disturbances are thought to contribute to physical symptoms and emotional dysregulation in adulthood. The current study investigated the effects of childhood trauma on young adults’ interoceptive accuracy as an indicator of brain-body communication that may be dysregulated by ELA. Sixty-six participants completed an online-questionnaire followed by a laboratory session including the socially-evaluated cold pressor stress test during which ECG, salivary cortisol and interoceptive accuracy were assessed. Childhood trauma was negatively related to interoceptive accuracy (IAc) after the stressor. This stress-effect could not be observed for heart rate and cortisol, which were unrelated to IAc. Participants reporting higher baseline unpleasantness exhibited lower IAc after the stressor, while increases in unpleasantness due to the stressor were associated with higher IAc. Unpleasantness at baseline mediated the effect of childhood trauma on IAc after the stressor. [less ▲]

South Africa is currently one of the world’s most unequal countries, with massive income inequality, millions of people living in poverty without access to basic services and amenities, unemployment rates consistently above 20% and the top 10% of the population receiving two thirds of the total income. Government economic policies on poverty reduction in the decades since the advent of democracy in South Africa in 1994 have been unable to eradicate the extreme racialised inequality which was the basis of the 342 years of colonialism and apartheid which were characterised by systematic dispossession and socio-economic marginalisation of South Africa’s majority Black population and the systematic privileging of the minority White population. While this history is not the primary focus of this paper, it nonetheless provides useful context. The paper’s primary focus is on the more recent normative and legal challenges of post-1994 South Africa that have resulted in further entrenching socio-economic inequality and contributing to the rise of populism. In this paper we argue that the dire living conditions of a large proportion of the population and disillusionment with the State’s ability to deliver on its promises in this regard, along with the poor implementation of social and economic rights have led to the development of a populist culture in South African politics.

Under the General Data Protection Regulation (GDPR), transparency of information becomes an obligation aimed at creating an ecosystem where data subjects understand and control what happens to their personal data. The definition of transparency stresses its user-centric nature, while design considerations to comply with this obligation assume central importance. This article focuses on the icons established by the GDPR Art. 12.7 to offer “a meaningful overview of the intended processing”. Existing attempts to represent data protection through icons have not met widespread adoption and reasons about the strengths and weaknesses of their creation and evaluation are here discussed. Building on this analysis, we present an empirical research proposing a new icon set that responds to GDPR requirements. The article also discusses the challenges of creating and evaluating such icon set and provides some future directions of research for effective an effective implementation and standardization.

Reducing pollutant emissions and promoting sustainable mobility solutions, including Public Transport (PT), are increasingly becoming key objectives for policymakers worldwide. In this work we develop an optimal vehicle scheduling approach for next generation PT systems, considering the instance of mixed electric / hybrid fleet. Our objective is that of investigating to what extent electrification, coupled with optimal fleet management, can yield operational cost savings for PT operators. We propose a Mixed In- teger Linear Program (MILP) to address the problem of optimal scheduling of a mixed fleet of electric and hybrid / non-electric buses, coupled with an ad-hoc decomposition scheme aimed at enhancing the scalability of the proposed MILP. Two case studies arising from the PT network of the city of Luxem- bourg are employed in order to validate the model; sensitivity analysis to fleet design parameters is performed, specifically in terms of fleet size and fleet composition. Conclusions point to the fact that careful modelling and handling of mixed-fleet conditions are necessary to achieve operational savings, and that marginal savings gradually reduce as more conventional buses are replaced by their electric counterparts. We believe the methodology proposed may be a key part of advanced decision support systems for policymakers and operators that are dealing with the on-going transition from conventional bus fleets towards greener transport solutions.

This paper examines the political economy and law of bank resolution in the case of Italy—specifically its treatment of three failing banks that were resolved in 2016/2017—Monte de Paschi, Veneto and Vicenza banks. These three cases stand out for the relatively large degree of discretion exercised by national resolution and state aid authorities, ultimately with the permission of their European counterparts. This paper examines the motivations driving Italian authorities to lobby the Commission for leeway in applying the Bank Recovery and Resolution Directive, and analyses the intricacies of the legal framework to underline the extent of discretion exercised by policy makers. It concludes that the discretion visible in these three cases is not (entirely) contained within EU law, and that bending the law or turning a blind eye to infractions was key to understanding the EU approach to Italy.

This paper explores the interface between central banks and cryptocurrencies. Focusing on the European Central Bank (ECB), it identifies the potential threats that the rise of cryptocurrencies would pose to the basic and ancillary tasks of the ECB, in particular, its monetary policy operations and the exercise of its supervisory functions over credit institutions and payment systems. The paper finds that cryptocurrencies can potentially have both direct – through their potential impact on the price stability and monetary policy, and central banks’ monopoly over issuing base money – and indirect effects on central banks, mainly through the institutions and systems that fall under the ECB’s scope of competence. To address the challenges posed by cryptocurrencies, the ECB may take both legal (including supervisory and oversight) measures and non-legal (or technical) measures. With respect to technical measures, the ECB - to the extent falling within the scope of its competence - may focus on improving the efficiency of existing payment systems and addressing the existing frictions in market infrastructures to indirectly affect the cryptocurrency markets. Alternatively, it can venture into issuing Central Bank Digital Currency (CBDC). Regarding legal measures, central banks could envisage regulating cryptocurrencies either directly or indirectly. However, as the most significant potential impact of cryptocurrencies on central banks is likely to be indirect through the impact of cryptocurrencies on the banking and payment systems, and given the limitations on the ECB’s mandate and its regulatory and supervisory tools, it is apposite for the ECB to consider using indirect strategies and tools to influence cryptocurrency markets. This indirect approach can be implemented through the ECB’s existing supervisory and oversight powers over the banking and payment systems. This paper specifies the direct and indirect measures and assesses their merits in addressing the concerns about cryptocurrencies. [less ▲]
