A framework for sustainable ecotourism : application to Costa Rica

Costa Rica is a small Central American nation that has gained an international reputation as a leader in environmental conservation. This has formed the base for its highly successful and lucrative small-scale ecotourism industry. However, there are threats from high rates of deforestation and expanding large-scale tourism that is trading on strong environmental credentials, so it is appropriate to conduct this policy analysis on such a significant ecotourism area. The paper develops an ecologically sustainable economic framework, drawing on the works of Adolph Lowe (1893-1995) and Michalstrok Kalecki (1899-1970), to examine the Costa Rican experience and then analyse lessons for general policy development of any ecotourism area. The analysis is conducted from a political economy (and not a tourism management) perspective on the trade-offs between small-scale and large-scale ecotourism.

Ecotourism in Costa Rica: an economic framework of analysis

Costa Rica is a small Central American nation that has gained an international reputation as a leader in environmental conservation. This has formed the base for its highly successful and lucrative small-scale ecotourism industry. However, there are threats from high rates of deforestation and expanding large scale tourism that is trading on strong environmental credentials. This paper sets out an ecologically sustainable economic framework to firstly examine the Costa Rican experience, and then analyse lessons for general policy development of any ecotourism industry. The analysis is conducted from a political economy perspective on the trade-offs between small-scale and large-scale tourism.

Effectiveness of IT-based diabetes management interventions: a review of the literature

Background : Information technology (IT) is increasingly being used in general practice to manage health care including type 2 diabetes. However, there is conflicting evidence about whether IT improves diabetes outcomes. This review of the literature about IT-based diabetes management interventions explores whether methodological issues such as sample characteristics, outcome measures, and mechanisms causing change in the outcome measures could explain some of the inconsistent findings evident in IT-based diabetes management studies.

Methods : Databases were searched using terms related to IT and diabetes management. Articles eligible for review evaluated an IT-based diabetes management intervention in general practice and were published between 1999 and 2009 inclusive in English. Studies that did not include outcome measures were excluded.

Results : Four hundred and twenty-five articles were identified, sixteen met the inclusion criteria: eleven GP focussed and five patient focused interventions were evaluated. Nine were RCTs, five non-randomised control trials, and two single-sample before and after designs. Important sample characteristics such as diabetes type, familiarity with IT, and baseline diabetes knowledge were not addressed in any of the studies reviewed. All studies used HbA1c as a primary outcome measure, and nine reported a significant improvement in mean HbA1c over the study period; only two studies reported the HbA1c assay method. Five studies measured diabetes medications and two measured psychological outcomes. Patient lifestyle variables were not included in any of the studies reviewed. IT was the intervention method considered to effect changes in the outcome measures. Only two studies mentioned alternative possible causal mechanisms.

Conclusion : Several limitations could affect the outcomes of IT-based diabetes management interventions to an unknown degree. These limitations make it difficult to attribute changes solely to such interventions.

Controlling the philosophical imaginary: reading Pierre Hadot with Luiz Costa Lima

This essay proffers a critical complement to Luiz Costa Lima's claims concerning the nature, history, and control of the imagination in Western culture. Accepting the wide scope of Costa Lima's critical claim about the socio-political control of imaginative literature in Western history, we claim that Pierre Hadot's work on philosophy as a bios in the ancient West cautions us lest we position philosophy in this history as always and necessarily an agency of control. At different times, philosophy has rather stood as an ally in practicing and promoting forms of criticity, and the playful, creative, and transformative envisaging of alternative ways of experiencing the world Costa Lima theoretically celebrates in literary fiction. Any critique of philosophy as always opposed to the critical imagination can only stand, we have argued, relative to philosophy as conceived on what Hadot suggests is but one, albeit the now hegemonic model: namely, as a body of systematic rational discourses, including discourses about the literary, poetics, and imaginary. What this vision of philosophy misses, Hadot shows, is how the ancient conception of philosophy (which survives in figures like Montaigne, Nietzsche, and Goethe) as a way of life promoted distinctly literary, aesthetic, and imaginative practices; first, to assist in the existential internalisation of the schools' ideas; secondly, to envisage in the sage and utopias edifying counterfactuals to help students critically reimagine accepted norms; and thirdly, in the conception of a transformed way of living and perceiving ‘according to nature’, whose parameters of autonomy and pleasurable contemplation of the singularity of the present experiences anticipate the experiences delineated in modern aesthetic theory.
