International research orientation of Swiss universities: self-regulated or politically imposed?

International openness is essential to science in small modern countries. The modernization of Swiss science and economy in the nineteenth century was promoted largely by foreigners: newly founded Swiss universities were staffed to a large extent by foreign professors, but students also came from abroad. Up to the middle of this century, the development of Swiss universities was marked by distinct successive phases of inviting in or shutting out international influence, depending mainly on changes in the political context. The international landscape of knowledge and science since the 1950s has undergone dynamic change. University structures were installed as a reaction to this dynamism. Patterns of international research orientation emerging in different universities and in the disciplinaryfields of business administration, chemistry and history are discussedin a comparative perspective.     

“If There's a Dance in the Book, I Feel It...Inside”: Lessons in Emergent Literacy

This case study illustrates the impact that an emergent literacy environment (both at home and at school) can have on literacy acquisition. The author's 3-year-old niece and 30 of her nursery school classmates were interviewed about their perceptions of reading. The impressive hypotheses the main character had formed about language learning by the age of 3, without any formal instruction, offers food for thought in view of the increasingly popular lockstep language arts programs currently being advocated by phonics zealots and basal text publishers.

Esports players,got muscle? Competitive video game players’ physical activity,body fat,bone mineral content,and muscle mass in comparison to matched controls

BackgroundEsports players, like traditional athletes, practice for long hours and, thus, are vulnerable to the negative health effects of prolonged sitting. There is a lack of research on the physical activity and the health ramifications of prolonged sitting by competitive players. The purpose of this study was to investigate activity levels, body mass index (BMI), and body composition in collegiate esports players as compared to age-matched controls.MethodsTwenty-four male collegiate esports players and non-esports players between 18 and 25 years of age signed a written consent to participate. Physical activity was examined using daily activity (step count) with a wrist-worn activity tracker. A questionnaire assessing physical activity was also administered. Secondary outcomes included body-fat percentage, lean-body mass, BMI, and bone mineral content measured using dual X-ray absorptiometry.ResultsThe step count in the esports players was significantly lower than the age-matched controls (6040.2 ± 3028.6 vs. 12843.8 ± 5661.1; p = 0.004). Esports players exhibited greater body-fat percentage (p = 0.05), less lean body mass (p = 0.003), and less bone mineral content (p = 0.03), despite no difference in BMI between the esports and non-esports players.ConclusionAs compared to non-esports players, collegiate esports players were significantly less active and had a higher body-fat percentage, with lower lean body mass and bone mineral content. The BMIs showed no difference between the 2 groups. Esports athletes displayed significantly less activity and poor body composition, which are all correlated with potential health issues and risk of injury. BMI did not capture this difference and should not be considered as an accurate measure of health in competitive esports players.     

Phase analysis in maximal sprinting: an investigation of step-to-step technical changes between the initial acceleration,transition and maximal velocity phases

Abstract

The aim of this study was to investigate spatiotemporal and kinematic changes between the initial acceleration, transition and maximum velocity phases of a sprint. Sagittal plane kinematics from five experienced sprinters performing 50-m maximal sprints were collected using six HD-video cameras. Following manual digitising, spatiotemporal and kinematic variables at touchdown and toe-off were calculated. The start and end of the transition phase were identified using the step-to-step changes in centre of mass height and segment angles. Mean step-to-step changes of spatiotemporal and kinematic variables during each phase were calculated. Firstly, the study showed that if sufficient trials are available, step-to-step changes in shank and trunk angles might provide an appropriate measure to detect sprint phases in applied settings. However, given that changes in centre of mass height represent a more holistic measure, this was used to sub-divide the sprints into separate phases. Secondly, during the initial acceleration phase large step-to-step changes in touchdown kinematics were observed compared to the transition phase. At toe-off, step-to-step kinematic changes were consistent across the initial acceleration and transition phases before plateauing during the maximal velocity phase. These results provide coaches and practitioners with valuable insights into key differences between phases in maximal sprinting.     

Extracting Latent Moral Information from Text Narratives: Relevance,Challenges, and Solutions

ABSTRACT

Moral Foundations Theory (MFT) and the Model of Intuitive Morality and Exemplars (MIME) contend that moral judgments are built on a universal set of basic moral intuitions. A large body of research has supported many of MFT’s and the MIME’s central hypotheses. Yet, an important prerequisite of this research—the ability to extract latent moral content represented in media stimuli with a reliable procedure—has not been systematically studied. In this article, we subject different extraction procedures to rigorous tests, underscore challenges by identifying a range of reliabilities, develop new reliability test and coding procedures employing computational methods, and provide solutions that maximize the reliability and validity of moral intuition extraction. In six content analytical studies, including a large crowd-based study, we demonstrate that: (1) traditional content analytical approaches lead to rather low reliabilities; (2) variation in coding reliabilities can be predicted by both text features and characteristics of the human coders; and (3) reliability is largely unaffected by the detail of coder training. We show that a coding task with simplified training and a coding technique that treats moral foundations as fast, spontaneous intuitions leads to acceptable inter-rater agreement, and potentially to more valid moral intuition extractions. While this study was motivated by issues related to MFT and MIME research, the methods and findings in this study have implications for extracting latent content from text narratives that go beyond moral information. Accordingly, we provide a tool for researchers interested in applying this new approach in their own work.     

Methods and Approaches to Using Web Archives in Computational Communication Research

ABSTRACT

This article examines the role of web archives as a critical source of data for conducting computational communication research. Web archives are large-scale databases containing comprehensive records of websites showing how those websites have evolved over time. Recent communication scholarship using web archives is reviewed, demonstrating the breadth of research conducted in this space. Subsequently, a methodological framework is proposed for using web archives in computational communication research. As a source of data, web archives present a number of methodological challenges, particularly with regards to the accuracy and completeness of web archives. These problems are addressed in order to better inform future work in this area. The closing sections outline a forward-looking trajectory for computational communication research using web archives.
