Strategies have been far more widely researched in conference interpreting than in the interactional setting of public service interpreting (PSI), although studies of the latter by Wadensjö and other authors suggest a strategic rationale for certain types of rendition (especially non-renditions). The present article describes an exploratory, qualitative study, based on roleplay, to identify strategies in PSI: the roleplays were designed to incorporate a variety of ‘rich points’, coinciding with peak demands on the interpreter’s problem-solving capacities and therefore particularly relevant to empirical study of interpreting strategies. Five interpreter-mediators with the Chinese–Spanish/Catalan language combination were each asked to interpret three different dialogues, in which the primary participants’ input was a re-enactment of real situations. Analysis of the transcribed video recordings was complemented by a preliminary questionnaire and by retrospective interviews with the interpreters. Their strategies, classified according to whether the problems concerned were essentially linguistic or involved the dynamics of interaction, in some cases reflect priorities typically associated with intercultural mediation. The advantages and limitations of using ‘rich points’ and roleplays in the study of interpreting strategies are briefly discussed

The work approaches theoretical and implementation issues of a framework for creating and executing Learning Objects (LOs) where problem-solving tasks are ordered according to the matching of two parameters, both calculated automatically: (1) student skill level and (2) problem solution difficulty. They are formally defined as algebraic expressions. The definition of skill level is achieved through a rating-based measure that resembles the ones of game mastery scales, while the solution difficulty is based on mistakes and successes of learners to deal with the problem. An empirical study based on existing students data demonstrated the suitability of the formulas. Besides, the motivational aspects of learning are considered in depth. In this sense, it is important to propose activities according to the student’s level of expertise, which is achieved through presenting students with exercises that are compatible with the difficulty degree of their cognitive skills. Also, the results of an experiment conducted with four highschool classes using the framework for the domain of logarithmic properties are presented.

Based on current research findings on the possibilities of integration of problem solving into mathematics teaching, the difficulties of pupils with problem solving tasks and of teachers to get started in problem solving, this article would like to show which concrete difficulties delayed the start of the implementation of a generally problem-oriented mathematics lesson in an eighth grade of a grammar school. The article briefly describes the research method of this qualitative study and identifies and discusses the difficulties of problem solving in the examined school class. In a next step, the results of this study are used to conceive a precise teaching concept for this specific class for the introduction into problem-oriented mathematics teaching.

The role of online communities is a key element in free and open source software (F/OSS) and a primary factor in the success of the F/OSS development model. F/OSS communities are inter-networked groups of people who are united by a common interest in F/OSS software. This chapter addresses holistic issues pertaining to member participation in F/OSS communities, specifically considering their reasons and motivation for participating. It collates the relevant literature on F/OSS community participation and presents the results of an empirical study into members’ perceptions of their own participation. We identify primary reasons for participation such as problem solving, support provision, and social interaction and rank their importance by the participants’ preferences. We then separate development and support activities and compare the community members’ perceptions of the two. Finally, we draw conclusions and discuss the potential for future research in this area.

AbstractThe New Legal Realist approach to international law builds from a jurisprudential tradition that asks how actors use and apply law in order to understand how law obtains meaning, is practised, and changes over time. The article addresses the jurisprudential roots of the New Legal Realism, its core attributes, and six important components in the current transnational context. In the pragmatist tradition, the New Legal Realism is both empirical and problem-centred, attending to both context and legal normativity. What is new is the rise of transnational activity that gives rise to an enlarged scope of transnational problem-solving through international law in radically new ways across areas of law, and the growth of empirical study of these phenomena. The article concludes by addressing the potential risks of the New Legal Realist approach in terms of scientism and relativism, and it responds to them.
