Executive functions (EFs) are key skills underlying other cognitive skills that are relevant to learning and everyday life. Although a plethora of evidence suggests a positive relation between the three EF subdimensions inhibition, shifting, and updating, and math skills for schoolchildren and adults, the findings on the magnitude of and possible variations in this relation are inconclusive for preschool children and several narrow math skills (i.e., math intelligence). Therefore, the present meta-analysis aimed to (a) synthesize the relation between EFs and math intelligence (an aggregate of math skills) in preschool children; (b) examine which study, sample, and measurement characteristics moderate this relation; and (c) test the joint effects of EFs on math intelligence. Utilizing data extracted from 47 studies (363 effect sizes, 30,481 participants) from 2000 to 2021, we found that, overall, EFs are significantly related to math intelligence (r = .34, 95% CI [.31, .37]), as are inhibition (r = .30, 95% CI [.25, .35]), shifting (r = .32, 95% CI [.25, .38]), and updating (r = .36, 95% CI [.31, .40]). Key measurement characteristics of EFs, but neither children’s age nor gender, moderated this relation. These findings suggest a positive link between EFs and math intelligence in preschool children and emphasize the importance of measurement characteristics. We further examined the joint relations between EFs and math intelligence via meta-analytic structural equation modeling. Evaluating different models and representations of EFs, we did not find support for the expectation that the three EF subdimensions are differentially related to math intelligence. [less ▲]

Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

The COVID-19 pandemic has not only sparked a renewed interest in history; it has also focused our attention on how the present can be historically preserved. Therefore, it is safe to predict that the COVID-19 crisis and its documentation will be analyzed by future historians, and it will bring about methodological and technological changes that affect our ways of working as historians of education. This chapter will examine the following: First, it looks at some basic characteristics of web archives and how they challenge our work as historians. Second, it offers reflections on different modes of archival access and on how this may affect current concepts of the past. Third, the chapter discusses how web archives relate to public history and, next, introduces the Education & Pandemics Archive launched by the International Standing Conference for the History of Education (ISCHE). The chapter will also provide preliminary insights into how web archives may affect our work as historians of education. Web archives offer different structures, opportunities for different interactions and technological environments. They can be characterized by collaborative processes by networked data within a flattened structure, and by interconnected hardware and software environments. Web archives are user-friendly, flexible and invite us to get involved and to develop new historical dimensions. [less ▲]

Numerous studies and handbooks in the history of education are devoted to the history of educational media and the evolution of educational technologies. This chapter puts an explicit focus on the implications and conceptual background of the United Nations Educational, Scientific and Cultural Organization´s (UNESCO) technology-driven idea of education, which already took shape before the 1957 Sputnik shock. Eager to establish strong bonds between mass communication and education, UNESCO by the late 1940s had already begun to set up a powerful internal apparatus for media policy which soon closely collaborated with its Education Division. From the late 1970s, UNESCO set out to establish a New World Information and Communication Order to further stabilize its global role in education and media policies. This chapter posits that textbooks, radio, TV, film, and computers were serving as interconnected elements of UNESCO’s educational mission. By looking at these specific technological ecologies of education, I connect research into the history of education with research into UNESCO´s media policies. This conceptual history approach demonstrates that education is not only based on ethical norms, teaching, and learning but is also connected to technological properties that offer access to knowledge and its acquisition. In addition, and when studying UNESCO, it becomes evident that the organization´s education-technology-nexus is also very much connected with the media and publishing industries. [less ▲]

Dieser Beitrag richtet sich auf die Fotografie als aktive Intervention innerhalb einer geschädigten oder gefährdeten Umwelt und bedient sich dieses Mediums, um neue Perspektiven der Bildungsgeschichte – in Bezug auf die bereits geschriebene und die zukünftige – zu entwickeln. Diese Perspektiven werden besonders deutlich, wenn sie vor dem Hintergrund gegenwärtiger Debatten zu Fragen der planetarischen Verantwortung und einer geteilten Welt entwickelt werden, die auch unsere Vorstellungen von Erziehung und Bildung prägen. Der Beitrag schlägt vor, dass sich die Forschung von einer anthropozentrischen Weltsicht, sowohl in positiver als auch in negativ verstandener Weise, innerhalb der historischen Bildungsforschung verabschiedet. Dies impliziert kritische Distanz zu jenen Konzepten, die die Souveränität und Freiheit des Menschen in den Mittelpunkt rücken, ferner Distanz zu Ideen der Modernisierung und zu ökonomischem Wachstum als Norm, Distanz gegenüber Fortschrittsdenken, starken Nationalstaaten und dem Glauben an eine effiziente Steuerung von Bildungssystemen, deren ökologische Konsequenzen insgesamt negiert wurden und werden. Entsprechend wird argumentiert, dass anthropozentrische Ansätze der Bildungsgeschichte die Offenheit und Vulnerabilität des menschlichen Körpers sowie dessen ethische, kulturelle und soziale Nähe zu anderen Lebewesen sowie zur materiellen Welt vernachlässigt haben.

We consider translation and dilation mappings acting on the spaces of meromorphic functions on the complex plane and the punctured complex plane, respectively. In both cases, we show that there is a dense $G_{\delta}$-subset of meromorphic functions that are common universal for certain uncountable families of these mappings. While a corresponding result for translations exists for entire functions, our result for dilations has no holomorphic counterpart. We further obtain an analogue of Ansari’s Theorem for the mappings we consider, which is used as a key tool in the proofs of our main results. [less ▲]

This chapter critically examines the claim that investment treaty awards have a final and binding character. It finds that, despite providing different mechanisms of collection, the ICSID and New York Conventions provide states with a tool to avoid compliance with investment treaty awards based on sovereign immunity rules. These rules have been invoked by states in an increasing number of cases, creating a hurdle for investors to obtain payment of the award. This chapter concludes with some potential remedies to the immunity bar. [less ▲]

Die grenzüberschreitende Studie wendet sich jungen Menschen zu, die in der Nachbetrachtung der Pandemie kaum Berücksichtigung fanden. Die Autor:innen analysieren zunächst die Pandemiefolgen für die duale Berufsausbildung an der deutsch-französischen Grenze. Dabei stützen sie sich auf eigene Interviews, die Einblicke in die Dynamiken der grenzüberschreitenden Kooperation im Berufswesen geben in einer Zeit, die nicht nur von Covid-19, sondern auch von einer institutionellen Neuordnung geprägt war. Im Weiteren stellen die Autor:innen die Ergebnisse einer eigenen Befragung von Studierenden grenznaher Bachelor- und Master-Studienprogramme in der Großregion vor. Sie wurde an der Universität des Saarlandes koordiniert und gibt Auskunft über die physische und virtuelle Mobilität von Studierenden, über ihre sozialen Kontakte sowie den Beratungs- und Unterstützungsbedarf in den Jahren 2020 und 2021. Mit anschaulichen Beispielen aus dem trinationalen UniGR-Master in Border Studies werden die Ergebnisse illustriert. [less ▲]

We present a unified approach to the design of social index numbers. Our starting point is a model that employs an exogenously given partition of the population into subgroups. Three classes of group-dependent measures of deprivation are characterized. The three groups are nested and, beginning with the largest of these, we narrow them down by successively adding two additional axioms. This leads to a parameterized class the members of which are based on the differences between the income (or wealth) levels of an individual and those who are better off. We then proceed to show that our measures are sufficiently general to accommodate a plethora of indices, including measures of inequality and polarization as well as distance-based measures of phenomena such as diversity and fractionalization.

How will the coronavirus disease 2019 (COVID-19) pandemic develop in the coming months and years? Based on an expert survey, we examine key aspects that are likely to influence the COVID-19 pandemic in Europe. The challenges and developments will strongly depend on the progress of national and global vaccination programs, the emergence and spread of variants of concern (VOCs), and public responses to non-pharmaceutical interventions (NPIs). In the short term, many people remain unvaccinated, VOCs continue to emerge and spread, and mobility and population mixing are expected to increase. Therefore, lifting restrictions too much and too early risk another damaging wave. This challenge remains despite the reduced opportunities for transmission given vaccination progress and reduced indoor mixing in summer 2021. In autumn 2021, increased indoor activity might accelerate the spread again, whilst a necessary reintroduction of NPIs might be too slow. The incidence may strongly rise again, possibly filling intensive care units, if vaccination levels are not high enough. A moderate, adaptive level of NPIs will thus remain necessary. These epidemiological aspects combined with economic, social, and health-related consequences provide a more holistic perspective on the future of the COVID-19 pandemic. [less ▲]

It is often said that the entrepreneurs of today are the family businesses of tomorrow. This assertion is supported by findings in a Global Entrepreneurship Monitor (2019-20) Report on ‘Family Entrepreneurship’ which cites that 75% of respondent entrepreneurs across 48 economies indicate that their family was actively involved in either starting or developing a new business . In spite of this, and the fact that it is becoming more popular for family firms to encourage entrepreneurialism within the younger generation, it is often challenging for Next Gens to ‘carve out’ an entrepreneurial identity for themselves. This is even more so the case if the intention is to pursue new ideas that are not central to the core business and which might disturb long-planned succession strategies, or expectations held by senior family members. Making the decision to get on board the entrepreneur(ship) is an important career decision that has huge implications, not only for the Next Gens who are planning this, but also for current members of the family business who might have to adjust their expectations.
