A hybrid numerical method to develop America’s Cup yacht appendages

A method aimed at the development of an America’s Cup racing yacht bulb is developed and validated against experimental data. The method relies heavily on Reynolds Averaged Navier Stokes computational fluid dynamics (CFD) and also factors in gravitational and aerodynamics effects through the use of a Velocity Prediction Program. Initial extensive use of towing tank results is made to be able to validate the CFD solution and thus develop a solid ground for predictive work. Then, in order to narrow down the focus on bulb developments, decoupled hypotheses are made on the influence of the hull and free surface wave. The development of a detailed performance analysis chart of a known base bulb allows the use of a relatively small series of CFD simulations together with physical hypotheses to assess any given bulb performance relative to the known base. The discussion of the results on a specific development highlights the promises and limitations of the method; final full scale results are discussed and analysed as well.     

The organizing and regulation of mountain guiding in Scandinavia 1820–2016, with a glance at the Alps

Abstract

In this article, we study how mountain guiding was organized and regulated in Scandinavia and the Alps between 1820 and 2015 and focus on the most important differences and similarities in Scandinavia, and between Scandinavia and the Alps. We conclude that Switzerland and Chamonix (France) represent two different systems in the Alps during the nineteenth century. However, through the emergence of national and international guide unions the regulation of mountain guiding in the Alps today appears unified, with a close connection between national regulation and mountain guide unions. In Scandinavia, Norway and Sweden historically had similar practices organizing and regulating mountain guiding, where a relatively strong layman tradition emerged during the 1960s and 1970s. In 2008, legal decisions led Sweden to change its system to match the Alp model, while Norway held on to the layman tradition. This leaves mountain guiding in Norway as a distinctly less regulated field than in France, and Switzerland, as in and Sweden.

ePedagogy as a threshold concept: a reflection on a programme for Science Teaching Assistants

Abstract

A Science Teaching Assistant (TA) Programme, at the University of the Western Cape (UWC), focused on preparing promising lecturers. A key component of this programme was the contribution by the Centre for Innovative Education and Communication Technologies (CIECT), which promoted the pedagogical adoption of eTools to assist development of Science TAs. A questionnaire enabled TAs to reflect on the eTools and CIECT’s sessions. The authors reflect on academic developer roles in higher education. Within CIECT’s contribution, ePedagogy was identified as a threshold concept that the TAs found challenging, but that could lead to transformed and improved teaching and learning.     

READING MATHEMATICS REPRESENTATIONS: AN EYE-TRACKING STUDY

We use eye tracking as a method to examine how different mathematical representations of the same mathematical object are attended to by students. The results of this study show that there is a meaningful difference in the eye movements between formulas and graphs. This difference can be understood in terms of the cultural and social shaping of human perception, as well as in terms of differences between the symbolic and graphical registers.     

Knowledge asset similarity and business relational capital gains: evidence from European manufacturing firms

This paper leverages the concept of absorptive capacity to explore whether similar configurations of intellectual capital (IC) are associated with the performance of relational capital in firms. It proposes a novel implementation of graph theory to analyse similarities in knowledge assets. We use Community Innovation Survey data to examine 5813 manufacturing firms in 13 business sectors and 13 European countries. While firms rely on external relations to compensate for a lack of internal assets, we find that a company’s propensity to cooperate in innovation is associated with its own IC profile. In particular, firms with common knowledge assets are more likely to benefit from business relational capital. The main contribution of this study lies in a holistic approach to understanding how similarities in knowledge assets are linked to gains in business relational capital.     

Fútbol para Todos (Soccer for All): Democratization,Populist Legitimization or Quasi-Authoritarianism?

Abstract

In 2009 the Argentine government of Cristina Fernández de Kirchner created Fútbol para Todos (Soccer for All), a programme that led to a policy of direct state intervention in the acquisition of government television rights for the transmission of soccer matches throughout Argentina. Does Fútbol para Todos serve as a tool for the democratization of Argentinean society, a strategy for populist legitimization, or as an embodiment of quasi-authoritarianism? Successive Argentine governments have politicized soccer. Fútbol para Todos has served as a tool for populist legitimization, but also as a strategy designed to legitimize state interference in a historically private domain, promote government propaganda through a new state monopoly, and strengthen governance processes through popular approval under the ambit of the ‘democratization’ slogan. Fútbol para Todos thus aims to use the state as an agent in the construction of better governance processes for all, but it also reinforces the historical union between soccer and establishment political power in Argentina. Fútbol para Todos is populist in tone and appears democratic, but also masks a darker undercurrent of quasi-authoritarian tendencies in Argentina.
