Instructed versus pharmacological effects of alcohol in alcoholics and social drinkers

Twelve alcoholics and 12 social drinkers were studied in an experiment where instructions about alcohol or placebo were orthogonally crossed with administration of alcohol or placebo in a Balanced Placebo Design. Three subjects were simultaneously observed while watching soccer games on the TV together and having free access to a mixed drink, which in the alcohol conditions contained 150ml of 80% proof vodka. The assessment procedure included several aspects of drinking behavior, behavioral observations during the session, psychiatric ratings and nurse observations before and after each session, ratings for craving, self-reported state anxiety and physiological changes (heart rate and blood pressure). In general, the results showed the alcoholic's behavior to be controlled by instruction-induced expectancies rather than by the actual beverage given, whereas the social drinkers showed tendencies in the opposite direction. The implications of these results for the traditional disease conception of alcoholism and for learning theory approaches are discussed.     

Perception of autonomic reactions and actual heart rate in phobic patients

The relationship between perceived physiological arousal and actual heart-rate reactions was studied in two behavioral test situations. The subjects were 70 phobic patients (34 social phobics and 36 claustrophobics) who were given the general form of the Autonomic Perception Questionnaire about 1 month before the respective behavioral test and the specific form immediately after the test. The results showed significant correlations between APQ and actual heart rate for the social phobics, while the picture was more complicated for the claustrophobics. The implications of these results are discussed.This research was supported by Grant 05452 from the Swedish Medical Research Council.     

Gender and power in school: On girls' open resistance

Drawing upon a Swedish empirical study of gender and power relations in a 9th-grade classroom, this paper focusses especially on girls' attempts to gain influence in school. Typically, such behaviours are reported to be more frequently exhibited by boys, as is almost all kinds of public classroom participation. In the class reported on here, however, girls are those actively contesting power relations and pursuing their principles. This is done through a process much resembling the idea of a representative democratic model. The features and implications of this process are elaborated in relation to two conflicts taking place in the class.     

Evaluating research institutions: Lessons from the CGIAR

Investing in research is a long-term, risky proposition. In agriculture, it could take fifteen years or more for a research finding to show an improvement in a farmer’s field. Yet, research institutions, like other organizations it needs to be evaluated. For more than twenty years, independent panels of outside experts have evaluated each of the international research centers that the Consultative Group of International Agricultural Research (CGIAR) supports. This paper examines the evolution of this review system, outlines the key methodological challenges faced, and draws lessons for others engaged in evaluating research institutions. It notes that the scope of the CGIAR reviews have been broadened over time in response to users’ concerns. Reviews now cover four dimensions of performance: research results, quality and relevance of research, vision and strategic directions, and management efficiency. The methodological challenges faced in measurement, valuation, and attribution are reviewed, along with practices found to be helpful in addressing these concerns. The paper concludes that the panel approach to institutional evaluation has served CGIAR’s needs well, and recommends it as an evaluation technique for integrating quantitative and qualitative dimensions of institutional performance. His recent work has concentrated on the governance and management of the CGIAR and the individual research centers it supports, including questions of evaluating management effectiveness.

Overweight and cognition

There is a growing concern among health authorities that an increasing number of people in the Western world become overweight and even obese. It is well known that obesity is related to several diseases (e.g., diabetes, stroke, and high blood pressure) and that such diseases related to obesity lead to early death. It has also been discussed whether overweight and obesity in themselves or in relation to such diseases lead to cognitive decline. On the basis of data from a large, population‐based, prospective study we examined three cognitive domains: episodic memory, semantic memory, and spatial ability. Two body measures were used to define normal weight and overweight, body‐mass index and waist/hip ratio. Although these two body measures reveal quite different prevalence data of overweight, the associations between overweight and cognition are similar. For episodic memory, overweight interacts with age, but when controlling for hypertension, stroke and diabetes, this interaction disappears. For semantic memory, normal weight participants outperform overweight participants even after controlling for these diseases. For spatial ability, the well‐established advantage for men holds for young‐old and old‐old normal‐weight participants. For overweight participants, this advantage holds for middle‐age participants only. We conclude that there is a weight‐cognition relationship even after controlling for obesity‐related diseases. The results are discussed in terms of possible biological mechanisms.     

QUALIA UND PHYSIKALISMUS

Qualia and Physicalism. It is assumed that the following three relations exhaust the possibilities for a physicalist account of qualia: 1. determination, 2. identity, 3. realization. The first relation is immediately rejected because it does not exclude property dualism. The second faces the problem that it is probably impossible to discriminate empirically between the identity thesis and the epiphenomenalist position. The third cannot handle qualia adequately, for qualia are not functional properties and the realization relation is only plausible as a relation between physical realizers and functional properties. Finally, if one attempts to replace multiple realization by multiple identities it is shown that the notion of multiple property identities is unintelligible. The upshot is that if these three relations exhaust the possibilities of a physicalist construal of qualia then physicalism is wrong.

Effects of Illness Representation,Perceived Quality of Information Provided by the Health-Care Professional,and Perceived Social Support on Depressive Symptoms of the Caregivers of Children with Leukemia

The present study examined the effects of illness representation, perceived quality of information provided by the health-care professional, and perceived social support on the depressive symptoms of the caregivers of children with leukemia. The sample was composed of 71 caregivers of children with leukemia living in Turkey. The obtained data were analyzed by path analysis. The results show that caregivers of children with leukemia experience higher levels of depressive symptoms when they have negative illness representation and lower levels of depressive symptoms when they perceive higher levels of social support. Moreover, they perceive higher social support when they perceive high quality of information provided by health-care professionals. It can be suggested that intervention programs which aim to increase caregivers’ social support and change their illness representation in a positive way would be helpful for the caregivers showing depressive symptoms.     

INTEGRAL ECOLOGY: THE WHAT,WHO, AND HOW OF ENVIRONMENTAL PHENOMENA

Providing an overview of Integral Ecology, this article defines and explains some of the key terms and concepts that underlie an approach to the environment that is inspired by and makes use of Ken Wilber's Integral Theory. First Integral Ecology is distinguished from other environmental approaches. Then Wilber's Integral Theory is introduced, which provides a foundation for a participatory approach to ecology. Next, the ontology, epistemology, and methodology of environmental phenomena is examined in light of Wilber's framework and illustrated with multidimensional examples of recycling. Finally, an Integral Ecology platform is presented.
