On perhaps becoming what you had previously despised: Psychologists as prescribers of medication

The authors contend that organized psychology's efforts to gain limited prescriptive privileges may be misguided. The modification of psychology's traditional scope of practice may produce harm in the form of lessened patient regard, devaluation of nonpharmacologic elements of practice, and markedly increased exposure to claims of malpractice. The authors also decry the disingenuous use of psychopharmacologically “underserved” populations as rationales for the pursuit of prescriptive privileges. Psychology may mount a major effort to make this change without sufficient justification, in the view of the authors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44851/1/10880_2005_Article_BF01989620.pd

Towards a framework for critical citizenship education

Increasingly countries around the world are promoting forms of "critical" citizenship in the planned curricula of schools. However, the intended meaning behind this term varies markedly and can range from a set of creative and technical skills under the label "critical thinking" to a desire to encourage engagement, action and political emancipation, often labelled "critical pedagogy". This paper distinguishes these manifestations of the "critical" and, based on an analysis of the prevailing models of critical pedagogy and citizenship education, develops a conceptual framework for analysing and comparing the nature of critical citizenship

Smaller and better: The university of Michigan experience

This paper discusses several hierarchical and sequential reduction options, including Balderston's budgetary strategies and this author's curricular change options. The latter are based on data gathered in a 1979-80 survey of 46 states on patterns of program reduction. Having introduced various reduction categories, the paper then focuses on the institutional shrinkage process currently being implemented at the University of Michigan. Four specific strategies are being discussed: (1) across-the-board cuts, (2) reduction of nonacademic programs; (3) long-range faculty reduction procedures, and (4) program discontinuance. A host of potential problems regarding the elimination of academic programs is described. The paper concludes by providing several general recommendations for institutional shrinkage procedures.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43589/1/11162_2004_Article_BF00992049.pd

Optic disc classification by the Heidelberg Retina Tomograph and by physicians with varying experience of glaucoma

PurposeTo compare the diagnostic accuracy of the Heidelberg Retina Tomograph's (HRT) Moorfields regression analysis (MRA) and glaucoma probability score (GPS) with that of subjective grading of optic disc photographs performed by ophthalmologists with varying experience of glaucoma and by ophthalmology residents.MethodsDigitized disc photographs and HRT images from 97 glaucoma patients with visual field defects and 138 healthy individuals were classified as either within normal limits (WNL), borderline (BL), or outside normal limits (ONL). Sensitivity and specificity were compared for MRA, GPS, and the physicians. Analyses were also made according to disc size and for advanced visual field loss.ResultsForty-five physicians participated. When BL results were regarded as normal, sensitivity was significantly higher (P<5%) for both MRA and GPS compared with the average physician, 87%, 79%, and 62%, respectively. Specificity ranged from 86% for MRA to 97% for general ophthalmologists, but the differences were not significant. In eyes with small discs, sensitivity was 75% for MRA, 60% for the average doctor, and 25% for GPS; in eyes with large discs, sensitivity was 100% for both GPS and MRA, but only 68% for physicians.ConclusionOur results suggest that sensitivity of MRA is superior to that of the average physician, but not that of glaucoma experts. MRA correctly classified all eyes with advanced glaucoma and showed the best sensitivity in eyes with small optic discs

Environmental and Economic Impacts of Growing Certified Organic Coffee in Colombia

According to advocates, eco-certification can improve developing country farmers' environmental and economic performance. However, these notional benefits can be undercut by self-selection: the tendency of relatively wealthy farmers already meeting eco-certification standards to disproportionately participate. Empirical evidence on this matter is scarce. Using original farm-level survey data along with matching and difference-in-differences matching models, we analyze the producer-level effects of organic coffee certification in southeast Colombia. We find that certification improves coffee growers' environmental performance. It significantly reduces sewage disposal in the fields and increases the adoption of organic fertilizer. However, we are not able to discern economic benefits

A future for game histories?

Recent years have seen an efflorescence of writing and curatorial work focused upon the past of video games. However, this work has tended to concentrate on particular forms of analysis, and privileged certain kinds of discourse. This article argues that these approaches limit our capacity to produce effective histories of and around games, and proposes more nuanced histories, informed by Foucauldian ideas of a genealogical approach to historical work, and a clear sense of the voices that present histories fail to represent. Broader, cultural game histories, we contend, offer us a clearer understanding of games’ past, and can move us away from the teleological, deterministic, and “great man” histories which dominate the present landscape. Reflecting on the past in this way also suggests an agenda for the future, in encouraging us to consider how and to what end we preserve video game culture

Long-range transport of airborne microbes over the global tropical and subtropical ocean

The atmosphere plays a fundamental role in the transport of microbes across the planet but it is often neglected as a microbial habitat. Although the ocean represents two thirds of the Earth’s surface, there is little information on the atmospheric microbial load over the open ocean. Here we provide a global estimate of microbial loads and air-sea exchanges over the tropical and subtropical oceans based on the data collected along the Malaspina 2010 Circumnavigation Expedition. Total loads of airborne prokaryotes and eukaryotes were estimated at 2.2 × 1021 and 2.1 × 1021 cells, respectively. Overall 33–68% of these microorganisms could be traced to a marine origin, being transported thousands of kilometres before re-entering the ocean. Moreover, our results show a substantial load of terrestrial microbes transported over the oceans, with abundances declining exponentially with distance from land and indicate that islands may act as stepping stones facilitating the transoceanic transport of terrestrial microbes.En prens
