Training in interactive sports

The general purpose of this systematic review was to study the effectiveness of off-court perceptual–cognitive training interventions in nonnovice, interactive sport athletes. We looked at task-specific practice effects and, more importantly, the transfer of effects. Databases used for the literature search were PubMed, Web of Science, and PsycINFO. In all, 16 studies were found to be eligible for this review. These studies were independently evaluated by four reviewers for methodological quality and their evidence for specific practice effects and transfer effects. The effectiveness was analyzed with respect to the level of transfer, i.?e., from training-task-specific effects to near-transfer (e.?g., a similar perceptual task), further-transfer (e.?g., a sensorimotor sports skill), and far-transfer (e.?g., competition performance) intervention effects. Analyses of the 16 included studies suggest that around 60% of the training-specific measures tested after off-court practicing perceptual–cognitive training in sports athletes signal performance enhancement. However, transfer, be it near, further or far, is mostly not studied empirically; if studied, there is currently only limited and weak evidence for intermediate and far transfer. To reason that perceptual–cognitive off-court training interventions are ineffective might be premature at this point of time as methodological quality can still be improved and only a very limited number of studies actually included transfer variables. In those few studies integrating transfer variables, results are mixed and inconsistent. Future work should focus on critical factors to assure transfer of perceptual–cognitive training interventions.

Computer based readers for intermediate foreign‐language students

The question that we are trying to answer in this article is how can computer technology and the WWW help us in enabling and motivating students to read in a foreign language? The article starts with some general considerations about the nature of foreign language teaching and the role of technology, as well as the research in the field of reading in general vs. computer assisted reading in particular, and is followed by the discussion of two computer based pedagogical readers. The article concludes with some suggestions for the development and design of new computer and on‐line readers for foreign language teaching. In this article, pedagogical readers are defined as authentic texts in a foreign language that are enhanced with interspersed questions, activities and glosses in multimedia format to assist low level students in learning how to read authentic texts and to understand them. This application is different from another very popular use of the WWW, namely as a source of authentic readings for students at more advanced language proficiency levels.Recueils des textes basés sur ordinateurs par les étudiants en langues vivantes. La question à laquelle nous essayons de répondre dans cet article est de savoir comment la technologie de l'ordinateur et le WWW nous aident à motiver les étudiants à la lecture des textes en langue étrangère. L'article débute par des considérations générales sur la nature de l'enseignement des langues étrangéres et le rôle de la technologie, aussi bien sur la recherche dans le champ de la lecture en général par rapport à la lecture assisté par l'ordinateur en particulier. L'article comporte ensuite une discussion sur deux recueils de textes pédagogiques fondés sur ordinateur. En conclusion on trouve des suggestions pour le développement et la conception de nouveaux recueils de textes online pour ordinateur pour l'enseignement des langues étrangères. Les recueils de textes pédagogiques sont définis comme des textes authentiques en langue étrangère renforcés par intervalles par des questions, des activités et des glosses et commentaires pour aider les étudiants de bas niveau à apprendre comment lire des textes authentiques et à les comprendre. Cette application est différente d'autre usage trés populaire du WWW, source de textes authentiques pour les étudiants à un niveau plus avancé.Computer basierte Leseprogramme für beginnende Fremdsprachenstudenten. Dieser Artikel geht der Frage nach, wie uns Computer und moderne Technologie helfen können, Schüler besser zum Lesen, in unserem Falle dem Lesen in einer Fremdsprache, zu befähigen und zu motivieren? Beginnend mit einigen allgemeinen Bemerkungen zum Fremdsprachenerwerb und zur Rolle von Technologie, zur Forschung auf dem Gebiet des Lesens mit und ohne Computerunterstützung, sowie gestützt auf die Diskussion zweier computergestützter pädagogischer Leseprogramme, soll der Artikel einige Anregungen für die Entwicklung und Gestaltung zukünftiger computergestützter Leseprogramme für den Fremdsprachenunterricht geben. Als pädagogische Leseprogramme bezeichnen wir in diesem Artikel fremdsprachige Orginaltexte, die durch eingeschobene Inhaltsfragen, Aktivitäten, Anmerkungen, Bilder und andere multimediale Hilfsmittel adaptiert wurden, um dem in der Fremdsprache noch relativ unerfahrenen Leser zu zeigen, wie man liesst, und um ihm zu helfen, das Gelesene zu verstehen. Diese Anwendung ist zu unterscheiden von einem anderen, sehr verbreitetem Gebrauch des Internets, nämlich als einer blossen Quelle für Originaltexte für fortgeschrittene Fremdsprachenlerner.     

Dreamings beyond ‘opportunity’: the collaborative economics of an aboriginal heritage trail

This article presents the Lurujarri Heritage Trail, an Indigenous tourism experience in Northwest Australia as exemplary for a world different from the teleological-minded futurism of neoliberal market economics. Drawing on long-term ethnographic fieldwork undertaken between 2011 and 2015, it first outlines how in 1987 the Trail was established at the very margins of the Australian economy. Through its emphasis on the here and now that is grounded in a collaboration of people and land and acknowledges diverse worldviews and ontological differences, the Trail today offers its participants a means to experience Indigenous culture as different from Western politics and development policies. As a result, its allegedly marginal Dreaming (Bugarrigarra) leads beyond the pursuit of economic opportunity and in doing so enabled the defeat of large-scale industrialisation in the region.     

Output-sensitive autocompletion search

We consider the following autocompletion search scenario: imagine a user of a search engine typing a query; then with every keystroke display those completions of the last query word that would lead to the best hits, and also display the best such hits. The following problem is at the core of this feature: for a fixed document collection, given a set D of documents, and an alphabetical range W of words, compute the set of all word-in-document pairs (w, d) from the collection such that w ∈ W and d ∈ D. We present a new data structure with the help of which such autocompletion queries can be processed, on the average, in time linear in the input plus output size, independent of the size of the underlying document collection. At the same time, our data structure uses no more space than an inverted index. Actual query processing times on a large test collection correlate almost perfectly with our theoretical bound.

Gender Differences in Self‐efficacy and Academic Performance among Students of Business Administration

Gender differences in perceived self‐efficacy and academic performance in marketing, organizational behaviour, accounting, computing, mathematics and statistics were investigated in 154 college students studying business administration. At the beginning of their second year in college, the students completed a questionnaire designed to measure self‐efficacy in subjects they had studied during their first year. The female students had significantly lower self‐efficacy in computing and marketing and higher self‐efficacy in statistics than the male students. Except for statistics, where female students outperform their male counterparts, there were no significant gender differences in academic performance.     

Dynamics of coordination within elite rowing crews: evidence from force pattern analysis.

For a rowing crew to be successful, the movements of the rowers need to be well coordinated. Because rowers show individual force patterns, they have to adapt their movements when rowing as a crew. In this exploratory study, these hypothesized changes in movement pattern were examined. The force graphs of six elite coxless fours crews were recorded over 11 training runs using strain gauges attached to the oars. A detailed force analysis showed that form differences, but not area differences, between force patterns decreased when force output increased as a result of two different processes. First, increasing force output reduced form differences instantaneously by reducing the individual variation in force patterns. Secondly, the kinaesthetic perception of form differences is easier than that of area differences. This better perception facilitates the adaptation of movement patterns, especially when force output is high.
