Within tutoring systems research, there has been a lot of recent interest in developing systems that adapt their responses to the student’s changing affect and attitude as conveyed during the human-computer interaction (e.g., (Forbes-Riley & Litman, 2010b; Conati & Maclaren, 2009; D’Mello et al., 2008; McQuiggan et al., 2008b; Porayska-Pomsta et al., 2008; Wang et al., 2008; Arroyo et al., 2007...

Scyphomedusae undergo a predictable ontogenetic transition from a conserved, universal larval form to a diverse array of adult morphologies. This transition entails a change in bell morphology from a highly discontinuous ephyral form, with deep clefts separating eight discrete lappets, to a continuous solid umbrella-like adult form. We used a combination of kinematic, modeling, and flow visuali...

Et Tu, Torsten? This critique of my Economic Policy paper generates many emotions. It is certainly an honor for my research to be taken seriously by such an eminent scholar as my friend Torsten Persson. And while any publicity is good, a negative citation dominates a positive one. There is irony; I came up with the original idea in a hallway conversation with Harry Flam a few feet from Persson’...

A traditional view of the nature of species holds that populations within species maintain genetic cohesion through substantial intraspecific gene flow and that the whole genome of a species is protected from interspecific gene flow by strong reproductive isolation. Both aspects of this view have been challenged. Reproductive barriers between recently evolved species can be incomplete and perme...

This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological informatio...

Two new species of Dolichothele Mello-Leitão, 1923 are described from Brazil and Bolivia, D. mottaisp. n. from Distrito Federal and the state of Goiás, Brazil, and D. camargorumsp. n. from the state of Rondônia, Brazil, and the La Paz region, Bolivia. Males of the two new species resemble Dolichothele bolivianum (Vol, 2001) in having a small subapical keel on the distal embolus and females in p...

This special issue focuses on “advanced scheduling strategies and Grid programming environments”, and is based on selected papers from the 6 International Workshop on Middleware for Grid Computing (MGC 2008) and 2 Latin American Grid (LAGrid 2008) workshop . The authors were invited to provide extended versions of their original papers taking into account comments and suggestions raised during ...

The transfer of heat radiation through clothing (Bröde et al., 2005; Clark & Cena, 1978; Lotens & Pieters, 1995) and the effects of moisture in different clothing layers (Bröde et al., 2008a; Havenith et al., 2008; Richards et al., 2008) have been studied separately. Also models predicting the heat gain from radiation (den Hartog et al., 2007; Lotens & Pieters, 1995) or the heat loss with wet c...
