Parasites are incredibly diverse. An important factor in the evolution of this diversity is the fact that many parasite species are restricted to 1, or just a few, host species. In addition, some parasites exhibit geographic specificity that is nested within their specificity to a particular species of host. The environmental factors that restrict parasites to particular regions within the host...

The determinants of human sensitivity to concurrent variable-interval variable-interval schedules of reinforcement have been difficult to identify, in part because of procedural differences separating published experiments. This experiment investigated vigilance to stimuli correlated with concurrent schedules. Across phases, 3 college students were provided with either no schedule-correlated st...

This paper presents a game with a purpose for the construction of a Portuguese lexicalsemantic network. The network creation is implicit, as players collaboratively create links between words while they have fun. We describe the principles and implementation of the platform. As this is an ongoing project, we discuss challenges and long-term goals.We present the current network in terms a quanti...

Phase 3 of the study is currently under way. One hundred and twenty students from the University of Sydney are being tested at six different times across their final medical school year (Year 4) and the internship year. The core measurement tools have again been administered and, in addition, the General Health Questionnaire,4 the International Personality Disorder Examination (IPDE, ICD-10 mod...

Many aspects of plant water use -- particularly in response to soil drought -- may have as their basis the alteration of hydraulic conductance from soil to canopy. The regulation of plant water potential (Psi) by stomatal control and leaf area adjustment may be necessary to maximize water uptake on the one hand, while avoiding loss of hydraulic contact with the soil water on the other. Modellin...

Man is, irl many ways, very unsuitable as an object for the study of genetics. Families are too small for dependable determination of ratios, desired test matings cannot be made, and study of more than a very few generations for 'my particular purpose is not often possible, The social implications of human genetics are so great, however, that the subject must be investigated; and there are some...

A review was conducted of studies that assessed the effects of acute bouts of physical activity on adults' cognitive performance. Three groups of studies were constituted on the basis of the type of exercise protocol employed. Each group was then evaluated in terms of information-processing theory. It was concluded that submaximal aerobic exercise performed for periods up to 60 min facilitate s...

The objective of this research proposal is to see how components can be used to map information from one system to an other. To do this a number of different problems must be addressed, and three groups of problems can be found. The first is how components work and how the other problems can benefit from that. The second is mapping, both syntactically and semantically. What information is neede...

Andre Carus (Hegeler Institute): “Carnap and Phenomenology: What Happened in 1924?” Abstract: The sketch of the Aufbau system in "Vom Chaos zur Wirklichkeit" (1922) employs phenomenology to describe the system basis, as do other writings before 1924. But in January 1925, we find a new principle of " ̈Überwindung der Subjektivität" and a new emphasis on "Einheit des Gegenstandsbereichs." Russell'...
