With the increasing availability of high-quality longitudinal data on students in higher education, scholars’ interest in how students proceed through higher education has risen. So far, the research field is diverse in theoretical perspectives and methodological approaches. Thus, based on 27 studies published in (higher) education research journals during the past two decades, this literature review provides an overview of the theoretical concepts, methodologies and main empirical findings in the study of students’ trajectories in higher education. The results depict a US dominated research field. Most theoretical frameworks are based on student’s decision-making. Across different country contexts and research designs—ranging from descriptions of student trajectories to studies predicting who engages in which types of trajectories to sequential trajectory reconstruction—we found that historically disadvantaged groups in higher education such as students from low social origin follow less linear and less smooth higher education trajectories. However, while the field of comparative education is growing steadily and may significantly contribute to explaining the link between the realization of students’ opportunities and the way how higher education is designed and implemented both on the national and local level, there were no cross-country comparison studies on higher education trajectories.

Most EU countries are experiencing an increased use of Collective Labour Agreement clauses – Social Rehire Clauses – that oblige incoming service providers, while taking over a service, to employ all or part of outgoing providers’ personnel or at least give these workers priority future hiring. In the established case law of the Court of Justice, rehiring personnel is considered a crucial element, which may trigger the application of Council Directive 2001/23 on transfers of undertakings. This article defends the need to keep Social Rehire Clauses outside the material scope of the Directive, in order to respect social partners’ collective autonomy and prevent opportunistic behaviours, while promoting a fair competition between employers. Constitutionally justified under Article 3(3) TEU, and Articles 9, 147 and 151(1) TFEU, the protection of employment pursued by Social Rehire Clauses should be interpreted as legitimate limitation to the economic freedoms enshrined in the Treaties and the Charter of Fundamental Rights.

Der Auszug der erwachsenen Kinder aus dem Elternhaus stellt für Eltern und junge Erwachsene gleichermaßen eine Transition in der Lebensspanne dar, die eine Regulation der familiären Beziehungen erforderlich macht und somit eine wichtige Familienentwicklungsaufgabe darstellt. Eltern sehen sich mit einer „empty nest“-Situation konfrontiert und mitunter kann sich das Loslassen für die Eltern als schwierig erweisen (Perrig-Chiello, 2014). Gerade im Jugend- und jungen Erwachsenenalter wird jedoch eine Anpassung der Beziehungen hin zu mehr Autonomie erforderlich, wohingegen Kontrolle und Einmischen seitens der Eltern zunehmend negativ erlebt wird. Insbesondere können sich hier unterschiedliche Zielsetzungen in den Beziehungen zwischen den Eltern und ihren erwachsenen Kindern ergeben, die mit dem Begriff des „intergenerational stake“ von Bengtson und Kollegen eingehend beschrieben wurden – junge Erwachsene streben einerseits nach Autonomie und Selbständigkeit, deren Eltern andererseits nach Kontinuität in den Beziehungen. Gleichzeitig bleiben Eltern für junge Erwachsene eine wichtige Quelle der Unterstützung und eine stabile Eltern-Kind-Beziehung bildet die Grundlage für eine gelungene Individuation (Buhl, 2003). Die Aushandlung der beiden fundamentalen Bedürfnisse nach Autonomie und Verbundenheit kennzeichnet Eltern-Kind-Beziehungen also ein Leben lang (Albert & Barros, 2017; Trommsdorff, 2006; Rothbaum & Trommsdorff, 2007). Was bedeuten diese widerstreitenden Tendenzen nun für die Qualität der Eltern-Kind-Beziehungen und insbesondere für das Erleben von Ambivalenz? Wie verändern sich die Eltern-Kind-Beziehungen mit dem Auszug aus dem Elternhaus? Diesen Fragen ist eine Studie an der Universität Luxemburg nachgegangen. Die Studie beschäftigte sich unter anderem mit den Ambivalenzerfahrungen junger Erwachsener und der Rolle des Auszugs aus dem Elternhaus. Befragt wurden junge Erwachsene im Alter zwischen 17 und 30 Jahren. [less ▲]

What does it mean to get older and eventually become an older citizen when residing in Europe? How do individuals deal with the challenges that result from health-related issues, novel cognitive demands, developmental tasks, and societal changes? How can societies offer the context for a good life to individuals, who have lived beyond their sixth decade of life, and may still have more than four decades to go? Research on aging does not point to just one other field of psychological science that one may consider as topical. In all, the five contributions to this special issue provide a rich and instructive compilation of articles that point to the potentials of aging research in basic and applied psychology. The diversity of these articles may also give an idea of the contributions and insights that can be gained from geropsychological work in psychology. This special issue has been a joint initiative of a longstanding network on geropsychology that has been established on the premises of EFPA. [less ▲]

Cross-national analyses of university curricula are rare, particularly with a focus on internationalization, commonly studied as impacting higher education through the mobility of people, programs, and campuses. By contrast, we argue that university knowledge shapes globalization by producing various sociopolitical conceptions beyond the nation-state. We examine variants of such a globalized society in 442,283 study programs from 17,129 universities in 183 countries. Three variants stand out, which vary across disciplines: an interstate model (prevalent in business and political science), a regional model (in political science and law), and a global model (in development studies and natural sciences). Regression models carried out on a subset of these data indicate that internationalized curricula are more likely in business schools, in universities with international offices, in those with a large number of social science offerings, and in those with membership in international university associations. We discuss these findings and their links to changes in universities’ environment, stressing the recursive relationship between globalization and higher education. [less ▲]

Task orientation is currently a prominent concept under discussion in primary school didactics. It focuses on tasks along which pupils acquire competences on distinct levels of competence. The qualitative empirical study TAPSE (Textbook Analysis in Primary Science Education) pursues the question which conception of task orientation is present in current textbooks in primary science education. The study follows two foci: (a) 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 (b) the analysis of 994 task statements in science textbooks with respect to the didactic 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 frequently sold series in the respective country. All tasks of the textbooks were analyzed deductively and inductively by four coders in three steps: (a) Identifying tasks with task-oriented potential; (b) itemizing different types of task-orientation potential; and (c) comparing the textbooks with respect to countryand period-specific manifestations of task orientation. Analysis indicated that (a) there are few tasks which meet the criteria of task orientation; (b) distinct types of task orientation can be generated, among which implicit forms dominate; and (c) differences 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 professional development for teachers, and support for pupils—in particular high achieving heterogenization.

While higher education research has paid considerable attention to the impact of both ratings and rankings on universities, less attention has been devoted to how university subunits, such as Schools of Education, are affected by such performance measurements. Anchored in a new institutional approach, we analyze the formation of a competitive institutional environment in UK higher education in which ratings and rankings assume a central position in promoting competition among Schools of Education (SoE). We apply the concepts of “ institutional environment” and “ organizational strategic actors” to UK SoE to demonstrate how such university subunits articulate their qualities and respond to the institutional environment in which they are embedded—by using ratings and rankings (R&R) to compete for material and symbolical resources as well as inter-organizational and intra-organizational legitimacy. Through findings from 22 in-depth expert interviews with members ofthe multidisciplinary field of education and a content analysis of websites (n = 75) of SoE that participated in REF 2014, we examine the stratified environment in which SoE are embedded (1). We uncover how R&R are applied by SoE within this competitive, marketized higher education system (2). Finally, we indicate the strategic behaviors that have been triggered by the rise of R&R in a country with a highly formalized and standardized research evaluation system (3). The results show both homogenization and differentiation among SoE in their use of organizational vocabulary and the applications of R&R while simultaneously revealing strategic behavior, ranging from changes in internal practices to changes in organizational structures.

[Context] In legal requirements elicitation, requirements analysts need to extract obligations from legal texts. However, legal texts often express obligations only indirectly, for example, by attributing a right to the counterpart. This phenomenon has already been described in the Requirements Engineering (RE) literature. [Objectives] We investigate the use of requirements templates for the systematic elicitation of legal requirements. Our work is motivated by two observations: (1) The existing literature does not provide a harmonized view on the requirements templates that are useful for legal RE; (2) Despite the promising recent advancements in natural language processing (NLP), automated support for legal RE through the suggestion of requirements templates has not been achieved yet. Our objective is to take steps toward addressing these limitations. [Methods] We review and reconcile the legal requirement templates proposed in RE. Subsequently, we conduct a qualitative study to define NLP rules for template recommendation. [Results and Conclusions] Our contributions consist of (a) a harmonized list of requirements templates pertinent to legal RE, and (b) rules for the automatic recommendation of such templates. We evaluate our rules through a case study on 400 statements from two legal domains. The results indicate a recall and precision of 82,3% and 79,8%, respectively. We show that introducing some limited interaction with the analyst considerably improves accuracy. Specifically, our human-feedback strategy increases recall by 12% and precision by 10,8%, thus yielding an overall recall of 94,3% and overall precision of 90,6%. [less ▲]

In this doctoral thesis, the low-dimensional algebraic cohomology of infinite-dimensional Lie algebras of Virasoro-type is investigated. The considered Lie algebras include the Witt algebra, the Virasoro algebra and the multipoint Krichever-Novikov vector field algebra. We consider algebraic cohomology, meaning we do not put any constraints of continuity on the cochains. The Lie algebras are considered as abstract Lie algebras in the sense that we do not work with particular realizations of the Lie algebras. The results are thus independent of any underlying choice of topology. The thesis is self-contained, as it starts with a technical chapter introducing the definitions, concepts and methods that are used in the thesis. For motivational purposes, some time is spent on the interpretation of the low-dimensional cohomology. First results include the computation of the first and the third algebraic cohomology of the Witt and the Virasoro algebra with values in the trivial and the adjoint module, the second algebraic cohomology being known already. A canonical link between the low-dimensional cohomology of the Witt and the Virasoro algebra is exhibited by using the Hochschild-Serre spectral sequence. More results are given by the computation of the low-dimensional algebraic cohomology of the Witt and the Virasoro algebra with values in general tensor-densities modules. The study consists of a mix between elementary algebra and algorithmic analysis. Finally, some results concerning the low-dimensional algebraic cohomology of the multipoint Krichever-Novikov vector field algebra are derived. The thesis is concluded with an outlook containing possible short-term goals that could be achieved in the near future as well as some long-term goals. [less ▲]
