London is Just Around the Corner: Belgium,Britain and Sport

Answering the legitimate call for a more transnational approach to the history of sport in Europe, we seize upon the 2012 Olympic Games as an opportunity to look back on Belgo-British contacts in sport since the Middle Ages. Contextualising this history within the wider Belgo-British political, economic and cultural contacts is, indeed, much more revealing than recounting a superficial story about the three medals the Belgian Olympic delegation actually obtained in London. We illustrate that transnational flows and contacts – crucial to the shaping and diffusion of sport – are not always reflected at the level of the Olympic Games. The cases of cycle racing and soccer demonstrate the divergent adoption and adaptation processes of specific sporting disciplines in Belgium and Britain. At the end of the paper, we also reflect on David Cameron's competitive sport policy in primary education, and raise the question whether the dissipation of public funds for elite sport – to the detriment of ‘Sport for All’ – is still defendable in times of government budgetary scarcity.     

Impact of early code‐skill and oral‐comprehension training on reading achievement in first grade

In a 3‐year longitudinal study, we examined the relationships between oral language development, early training and reading acquisition on word‐identification and reading‐comprehension tests administered to a sample of 687 French children. Hierarchical linear models showed that both phonological awareness and oral comprehension at the age of 4 years were relevant to reading acquisition 2 years later. These two broad skills explained separate parts of the variance on both outcome measures, while revealing opposite effects: phonological skills explained more variance for alphabetic reading skills and oral comprehension explained more variance for reading comprehension. We also assessed the effects of two preschool training programmes focusing on either phonological awareness or comprehension skills. The results showed that phonological awareness training had a positive effect on alphabetic scores, and comprehension training had a positive effect on reading comprehension. These results provide insight into early oral instruction and contribute to the theoretical debate about the linguistic predictors of literacy acquisition.     

The Effects of Teachers’ Training on Pupils’ Achievement: The Case of Elementary Schools in France

This investigation examines the effects of teachers’ training on pupils’ achievement in French and mathematics. The aim of the research is to compare the effectiveness of three samples of elementary school teachers with different levels of experience and training. Using a multilevel model, the results demonstrate that training enhances the effectiveness of novice teachers. In addition, experience was also found to have a positive effect. Neither training nor experience have a significant effect on equity, defined as the capacity of reducing the initial gap between high and low achieving pupils.

Media-specific rate allocation in heterogeneous wireless networks

INTRODUCTION With the development of novel wireless tech- nologies and increasing available bandwidth, multi- media applications over wireless networks become attractive for both businesses and end users. Fast de- ployment of Wi-Fi HotSpots, increase in wireless coverage of remote habitable areas (Wi-Max, or wireless mesh networks), improved data services over the 2G cellular systems and the long awaited debut of 3G wireless services offer many potential and inter- operable communicatio…     

Biological Pest Control of a Biscuit Beetle (Stegobium paniceum) Infestation in an Old Masters Paintings Storage Area

ABSTRACT

We report on biological control of an active infestation by biscuit beetles (Stegobium paniceum) of museum objects (Old Masters paintings) in the storage facilities of the Museum of Fine Arts in Vienna. Because chemical and non-chemical treatment methods would have been very problematic, the release of parasitic wasps (Lariophagus distinguendus) was discussed and accepted by the director of the collection. We released 3000 wasps every month from August 2013 until September 2014 in the two infested storage rooms and monitored the activity of biscuit beetles on sticky blunder traps and light traps, and also by visual inspection. In the insect monitoring of 2014 until 2018 no more biscuit beetles were found in the two storage depositories, showing that the treatment was 100% successful. To our knowledge, this is the first proof of a fully successful biological control of a museum pest using parasitoids only, and also of stored product/food pest, outside a laboratory experimental setup. This biological pest control method allowed avoiding negative side effects such as contamination from treatments with biocides, or costly logistics in case of chemical-free methods.     

Extending the testimony problem: evaluating the truth, scope, and source of cultural information

Children's learning--in the domains of science and religion specifically, but in many other cultural domains as well--relies extensively on testimony and other forms of culturally transmitted information. The cognitive processes that enable such learning must also administrate the evaluation, qualification, and storage of that information, while guarding against the dangers of false or misleading input. Currently, the development of these appraisal processes is not clearly understood. Recent work, reviewed here, has begun to address three important dimensions of the problem: how children and adults evaluate truth in communication, how they gauge the inferential potential of information, and how they encode and evaluate its source.     

The effects of representational format on learning combinatorics from an interactive computer simulation

The current study investigated the effects of different external representational formats on learning combinatorics and probability theory in an inquiry based learning environment. Five conditions were compared in a pre-test post-test design: three conditions each using a single external representational format (Diagram, Arithmetic, or Text), and two conditions using multiple representations (Text + Arithmetic or Diagram + Arithmetic). The major finding of the study is that a format that combines text and arithmetics was most beneficial for learning, in particular with regard to procedural knowledge, that is the ability to execute action sequences to solve problems. Diagrams were found to negatively affect learning and to increase cognitive load. Combining diagrams with arithmetical representations reduced cognitive load, but did not improve learning outcomes.
