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…     

Educating Art in a Globalizing World. The University of Ideas: A Sociological Case‐study

In 1999, the Italian Arte Povera artist Michelangelo Pistoletto and other artists laid the foundations of The University of Ideas (UNIDEE), an exceptional international artist‐in‐residence programme with a strong ideological foundation. As a sociologist of culture I had the opportunity to do research in the huge organization for a month by doing participant observation, in‐depth interviews and discourse analysis. In this article the educational programme of UNIDEE is interpreted in sociological terms. First of all it will be contextualized in the artistic work of Michelangelo Pistoletto through his concept of the mirror and his a‐modern idea of ‘The Minus Artist’. In the second part Pistoletto's artistic, political and economic movement Cittadellarte, in which UNIDEE is based, will be described. Finally UNIDEE will be analysed as a model for art education on the border of modernity attempting to redefine the position of art and of the artist in a globalizing world.     

Knowledge, Concepts, and Inferences in Childhood

The role of knowledge in children's inferences was investigated in 3 experiments. Experiment 1 examined developmental changes in the role of categorical membership, perceptual appearance, and item complexity in inferences for natural kind and artifact concepts. Preschoolers (5-year-olds), second graders (8-year-olds), and fourth graders (10-year-olds) were taught novel properties about target concepts and asked whether each of 4 probes had those properties. Probes varied in category membership and perceptual appearance relative to the target item. Item complexity also varied. Experiments 2 and 3 examined inferences with known and unknown concepts for familiar and unfamiliar properties. Older children's knowledge led to differential weighting of categorical information over appearance but only for known concepts and/or familiar properties. Preschoolers made no distinction between category and appearance for either known or unknown concepts. Additionally, as target item complexity increased, older children made more inferences than preschoolers. No differences between inferences about natural kind and artifact concepts were found. The role of theories and knowledge in children's drawing of inferences is discussed.     

Conflicting Views of Realistic Professionalism: Preservice Educators' Concerns Arising from Analysis of Themes in Their Reflective Writings

Current demands for professionalism from society are great, and future educators are concerned that they do not have the stamina and resources to fulfill their personal roles. This research examines 453 reflective writings of 151 preservice teachers, child and youth care providers, and counselors who, despite being asked to identify how their learning could help children, also wrote about their professional concerns. The 406 expressed concerns were identified based on 86 vocabulary leads. The categories of concern were (a) Misbehaviour, Aggression, Violence, and Victimization, (b) Multiculturalism and Diversity, (c) Personal Preparation and Career Choice, (d) The Responsibility of Providing Appropriate Teaching and Learning Methods, and (e) Appropriate Involvement in Children's Lives. The overall highest concern was for Personal Preparation and Career Choice, although the second highest concern for Misbehavior, Aggression, Violence, and Victimization increased dramatically after a special unit on childhood discipline practices was presented to the participants.     

A Historical Examination of Self-Regulation: Helping Children Now and in the Future

Using content and archival analysis as a mixed method research design, this study addresses the broad issue of self-regulation since this subject area first appeared in the developmental psychology journals, addressing the question of whether each historical period had its own particular perspective on self-regulation, or was there, in fact, a progressive development? This research also explored the historical basis of current perspectives in order to provide background and continuity for present theories and the discussion of implications for families, professionals, and communities in supporting the development of self-regulation in infants and children.     

THE PARENTS COUNCIL

The aim of this article is to consider the psychological mechanisms that may prevent individuals from achieving religious tolerance and religious pluralism. After defining these concepts and explaining why they are desirable outcomes, four psychological obstacles to the achievement of religious tolerance and religious pluralism will be explored by considering both research in psychology and the literature on religious education. The aim of identifying these obstacles is to enable us to suggest how they might be overcome through education, and what the implications for religious education are.     

Policy,practice, and reality: exploring a nation-wide technology implementation in Turkish schools

Technology has already become an indispensable part of our lives, and nations around the world see schools as the main agents to prepare their youth for a technology-filled future, and invest important amounts of funding to provide hardware to schools, students and teachers. The Turkish Ministry of National Education is in the midst of the FAT?H project, a nation-wide attempt to provide each classroom with an interactive whiteboard and each student with a tablet computer. In this paper, the authors present interview data from teachers at first-year FAT?H pilot schools who are using these technologies to understand how this national attempt is being translated into practice, and identify what is working and what areas need further attunement. Results show that teachers were especially content with being able to make their lessons visually more appealing for their students. They were, however, not satisfied with the in-service training provided, especially in understanding ways to effectively integrate the technologies into their teaching, and the limitations put upon Internet access from the tablets. The impacts of these tools on their teaching practices were very minimal.     

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.
