Spiders in Fauna Europaea : dual use of the database
The history and current work of the project Fauna Europaea is outlined. The different sources used for building up the database and the efforts to keep it updated are described. Available models of national checklists are discussed and the ideal checklist is described. The double use of the database as a matrix behind the official site of Fauna Europaea – as well as a directly visible document on the website of the European Society of Arachnology – are indicated and the differences in transparency, links to literature sources, and facilities such as distribution maps and calculations of numbers of scores per species or of species per country are discussed. The future of the project is briefly outlined. The need for a European identification tool for spiders is stressed
Linyphia triumphalis : a junior synonym of Centromerus pabulator (Araneae, Linyphiidae)
Linyphia triumphalis Denis, 1952 was found to be a junior synonym of Centromerus pabulator (O.P.-Cambridge, 1875) (Araneae, Linyphiidae). New synonymy
Spiders in a hostile world (Arachnoidea, Araneae)
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders. Kleptoparasites are found among spiders as well as among Mecoptera, Diptera, Lepidoptera, and Heteroptera. Predators are found within spiders’ own population (cannibalism), among other spider species (araneophagy), and among different species of Heteroptera, Odonata, and Hymenoptera. Parasitoids are found in the orders Hymenoptera and Diptera. The largest insect order, Coleoptera, comprises a few species among the Carabidae which feed on spiders, but beetles are not represented among the kleptoparasites or parasitoids
Judgments of Learning in Collaborative Learning Environments
Helsdingen, A. S. (2010, March). Judgments of Learning in Collaborative Learning Environments. Poster presented at the 1st International Air Transport and Operations Symposium (ATOS 2010), Delft, The Netherlands: Delft University of Technology.Professional environments such as Air Traffic Control are characterized by increasing interdependency and complexity. As the complexity of the situation and environment increases, it becomes more unlikely that an individual will be able to manage the situation alone. Therefore, organizations are increasingly using teams to handle difficult, complex situations.
Many studies on effective team performance show that effective teams have developed specific team behaviors such as supporting each other, re-allocating tasks to share workload, taking initiative, and providing relevant information to other team members (Stout, Cannon-Bowers, Salas & Milanovich,1999). Such behaviors rely on team members having an adequate awareness of other team member’s performance and workload (Entin & Serfaty, 1999; Stout, Cannon-Bower, Salas & Milanovich, 1999). Similarly, we expect that for effective team learning in a collaborative environment, it is essential to be able to adequately assess one’s own and other team members’ learning progress and share workload. In recent years, the interest in cognitive strategies such as self-monitoring and self-regulation in cognitive and learning research has grown considerably (Koriat, 1998; Nelson & Narens, 1990). Adequate self-monitoring is important, especially in self-directed learning programs, because it determines the effort and time an individual spends on learning something or taking extra measures so as to prevent forgetting (Koriat, 1997). However, these cognitive strategies, such as Judgments of Learning, have mainly been studied in individual learning environments. Therefore, this study aims to investigate how adequate judgments of learning can be supported in a collaborative learning environment and whether these contribute to individual and team learning. The poster will outline the relevant theory on collaborative learning and Judgments of Learning, the hypotheses and the experimental approach that is foreseen.Knowledge development center Mainport Schipho
