Information needs related to extension service and community outreach.

Air quality affects everyone. Some people are affected by air quality impacts, regulations, and technological developments in several ways. Stakeholders include the medical community, ecologists, government regulators, industries, technology providers, academic professionals, concerned citizens, the news media, and elected officials. Each of these groups may perceive problems and opportunities differently, but all need access to information as it is developed. The diversity and complexity of air quality problems contribute to the challenges faced by extension and outreach professionals who must communicate with stakeholders having diverse backgrounds. Gases, particulates, biological aerosols, pathogens, and odors all require expensive and relatively complex technology to measure and control. Economic constraints affect the ability of regulators and others to measure air quality, and industry and others to control it. To address these challenges, while communicating air quality research results and concepts to stakeholders, three areas of information needs are evident. (1) A basic understanding of the fundamental concepts regarding air pollutants and their measurement and control is needed by all stakeholders; the Extension Specialist, to be effective, must help people move some distance up the learning curve. (2) Each problem or set of problems must be reasonably well defined since comprehensive solution of all problems simultaneously may not be feasible; for instance, the solution of an odor problem associated with animal production may not address atmospheric effects due to ammonia emissions. (3) The integrity of the communication process must be preserved by avoiding prejudice and protectionism; although stakeholders may seek to modify information to enhance their interests, extension and outreach professionals must be willing to present unwelcome information or admit to a lack of information. A solid grounding in fundamental concepts, careful and fair problem definition, and a resolute commitment to integrity and credibility will enable effective communication of air quality information to and among diverse stakeholders.

e-Phys: a suite of intracellular neurophysiology programs integrating COM (component object model) technologies.

Current computer programs for intracellular recordings often lack advanced data management, are usually incompatible with other applications and are also difficult to adapt to new experiments. We have addressed these shortcomings in e-Phys, a suite of electrophysiology applications for intracellular recordings. The programs in e-Phys use Component Object Model (COM) technologies available in the Microsoft Windows operating system to provide enhanced data storage, increased interoperability between e-Phys and other COM-aware applications, and easy customization of data acquisition and analysis thanks to a script-based integrated programming environment. Data files are extensible, hierarchically organized and integrated in the Windows shell by using the Structured Storage technology. Data transfers to and from other programs are facilitated by implementing the ActiveX Automation standard and distributed COM (DCOM). ActiveX Scripting allows experimenters to write their own event-driven acquisition and analysis programs in the VBScript language from within e-Phys. Scripts can reuse components available from other programs on other machines to create distributed meta-applications. This paper describes the main features of e-Phys and how this package was used to determine the effect of the atypical antipsychotic drug clozapine on synaptic transmission at the neuromuscular junction.

The socio-economic landscape of biotechnology in Spain. A comparative study using the innovation system concept.

Biotechnology is becoming a crucial factor for the innovation strategies of the industrialised countries. Thus, the analysis of the sector is gaining relevance for the identification of the technological strength and potential of a country (or region) in a context of globalisation. A specific national case study may serve for more general comparative analyses. We have selected the case of Spain as illustrative of the complexity and differences existing in Europe. By using the analytical framework of the "national systems of innovation" concept, we have performed a multistep analysis of the biotechnology sector in Spain, focussing first on regions of Madrid and Cataluña which together account for more than 50% of the sector in Spain. The firms in both regions have followed a common strategy based on diversification and investment in R&D and innovation, so as to be able to compete in an international and competitive environment. There are, however, some interesting differences between the two subsectors; the one from Cataluña being more based on industrial traditions, and the one from Madrid characterised by the emergence of more specialised firms. The study has been extended to the remainder of Spanish firms for comparative purposes. The case of Spain is illustrative of the divergences existing in the biotechnology sector in Europe. A comparison is made with the structural and organisational characteristics of the biotechnology sector in several European countries. It shows that there is diversity in the pattern of commercialisation between countries and within regions of countries. Understanding these differences may assist the design of appropriate policies to promote the development of biotechnology in Europe.

Measuring geographic inequities in the Portuguese health care system: an estimation of hospital care needs.

Portugal created a NHS to achieve greater equity of access to health care. Successive governments continued to assert the importance of equity in the face of evidence of inequities in supply of hospital resources, but lacked methods to provide sound information on the degree of inequities in Portugal and hence how to achieve greater equity. Capitation formulae have been increasingly used in other countries with a NHS to measure geographical inequities and allocate resources to reduce them. The main objective of this paper was to develop a capitation formula to measure need for hospital care for the Portuguese system by transferring this technology from methods used in other countries, and, in particular, in England. We find, however, problems with the common use of standardised mortality ratios (SMRs) as a measure of need and found age-specific mortality ratios to offer more soundly-based estimates. We also raise questions on the use of empirical estimates of utilisation of health care by age and sex as they appear to reflect inadequacies of health care in Portugal. We also believe it is important to improve knowledge of health insurance and care outside the NHS. Our results show that there are considerable inequities on the distribution of hospital resources in Portugal.

Transaction costs economics as a conceptual framework for the analysis of barriers to the diffusion of telemedicine.

Telemedecine has been talked about for more than 20 years, without it entering daily use with any success. Based on transaction costs economics, the present analysis of the exchange relationships between health care producers highlights certain characteristics of the current technical and legislative context, which leads to transaction costs. It also demonstrates that the introduction of telemedicine shifts the costs associated with agents' opportunism from patients to health-care producers themselves. All these costs may be considered nowadays to thwart the use of telemedicine. It is argued here that the Public Authorities and professionals of health care could act upon telemedicine in two fields: (1) intervention in the institutional environment aims notably at better defining the property rights of telemedicine, and so constitutes an unavoidable means of encouraging health-care producers to invest in new technology; and (2) implementation of organisational forms and mechanisms susceptible to regulating such telemedical relationships between health care producers-given the present institutional environment-constitutes an essential means for overcoming the immediate barriers blocking the diffusion of telemedicine.

The impact of the UK NHS purchaser-provider split on the 'rational' introduction of new medical technologies.

This article uses evidence from case studies of the introduction of three new medical technologies to explore the impact of the UK NHS purchaser--provider split on the diffusion of new medical technologies. A desirable policy objective is assumed to be the 'rational' diffusion of medical technologies according to evidence that they are clinically and cost effective. Theoretical mechanisms are identified through which diffusion could be controlled, and the case studies are used to explore the extent to which rational technology diffusion occurs in practice in the NHS. They illustrate the influence of purchasers and providers on the introduction and early use of new technologies and explore the extent to which research about clinical and cost effectiveness is used to inform decisions about technology adoption. The results demonstrate the limited influence of purchasers and the short term clinical and organisational objectives pursued by providers in relation to technology adoption. It is suggested that initiatives to promote rational technology diffusion might be most effective if they are focused on decision making in providers, and if they aim to balance the influence on decisions of administrative and financial information about the technologies with more systematic use of research about clinical and cost effectiveness.

Diffusion of laparoscopic technologies in Denmark.

It has been predicted that minimally invasive therapy will have dramatic consequences for the specialty of general surgery, as demonstrated by the diffusion of laparoscopic cholecystectomy. To investigate the determinants of the diffusion in Denmark of five laparoscopic technologies (cholecystectomy, appendicectomy, surgery for colon cancer, surgery for inguinal hernia and fundoplication), questionnaires on seventeen factors' influence on the adoption (stimulating or impeding) were sent to fifty-nine hospitals. Fifty hospitals (85%) responded. Overall, 98% adopted laparoscopic cholecystectomy in Denmark between 1991 and 1995, whereas the remainder of the technologies were adopted by 7-65% of hospitals performing these operations. Large and specialized hospitals were the earliest adopters. The factors, nature of technology (minimally invasive versus conventional), training (appropriate training courses), competition (between specialties and between hospitals) and media attention have stimulated the diffusion, whereas three budget factors (budget for investment, budget for operation and public regulation) usually had an impeding effect. Stimulating factors prevail for all laparoscopic technologies indicating that some guidance of the adoption and use of new health technologies might be necessary. In Denmark, one of the suggested health policies to secure timely guidance is the establishment of an early warning system.

"It's some kind of women's empowerment": the ambiguity of the female condom as a marker of female empowerment.

The female condom is the latest in a series of sexual and reproductive technologies to be imported into the third world, following the contraceptive pill, the Depo-Provera injection, the latex male condom, and others. It is an example of "traveling technology", which accrues different meanings and connotations in the different settings into which it is introduced in its journey through the circuits of international technological diffusion, from the headquarters of international NGOs and bilateral aid programs, through the bureaucracies of national ministries of health to the communities in urban and rural settings where the condoms are distributed. The female condom almost always carries connotations of women's empowerment, and the possibility of greater sexual autonomy for women. This association is a result of the female condom being the first new "post-Cairo" technology, the diffusion of which was spurred by the consensus reached at the 1994 International Conference on Population and Development in Cairo, at which the need to promote women's empowerment was moved to the center of international family planning and population movements. However, I demonstrate that "empowerment" is an ambiguous term, interpreted in different ways in different contexts. I illustrate this through interviews conducted in 1998 and 1999 with stakeholders in the female condom in Cape Town, Nairobi, and in rural western Kenya. These stakeholders range from directors of US-based development programs to heads of national AIDS-prevention efforts to community-based distributors and primary health care nurses at the village level. I argue that three different notions of empowerment are being articulated with respect to the female condom--two which correspond to Maxine Molyneux's typology of strategic and practical gender interests, and a third in which women's empowerment is conceived of as something which diminished the power of men. I argue further that the disjunctures between these three different notions of what "empowerment" means will pose a challenge for people at all levels which are seeking to make the female condom more widely accessible to women at risk of HIV/AIDS.

A review of successful transport and home injury interventions to guide developing countries.

Injury is recognized as an increasing public health problem in developing countries. Extensive research on injury control has been conducted in the U.S. and other industrialized countries in the past several decades, but research is still in its infancy in developing countries. In this paper, successful interventions for transport and home injuries are reviewed in the context of the developing country setting. The aim is to evaluate injury interventions developed in the industrialized countries and identify those likely to be usable in developing countries. The evaluation criteria used include the efficacy of the interventions, as well as their affordability, feasibility and sustainability. The review demonstrates that while several interventions are available in the field of injury prevention for developing countries to import, caution should be taken in doing this. The use of automobile safety seat belts, bicyclist and motorcyclist helmets, speed limits, laws banning the sale of alcohol at lorry parks, pedestrian crossing signs, adequate roadway lighting, separation of pedestrians from vehicles, conspicuity-enhancement measures, simple safety equipment, and poison prevention packaging should be seriously considered by developing countries to reduce the morbidity and mortality from transport and home injuries. Since injury prevention may often require a blend of several interventions due to the multifactorial nature of the causes of injury, interventions that appear to be most effective are those with multidimensional strategies including education, legislation and environmental modification. This review should serve as a useful guide to injury control efforts in developing countries which must grapple with limited resources and low levels of education.

The health transition, global modernity and the crisis of traditional medicine: the Tibetan case.

The epidemiologic and demographic consequences of the health transition, coupled with worldwide pressures for health care reform according to neoliberal tenets, will create new opportunities, and well as new problems, for organized systems of indigenous medicine. Spiraling costs of biomedically-based health care, coupled with an increasing global burden of chronic, degenerative diseases and mental disorder, will produce significant incentives for the expansion of indigenous alternatives. Yet this expansion will be accompanied by pressures to rationalize and modernize health care services according to the structurally dominant scientific paradigm. Without concerted effort to maintain native epistemologies, indigenous medical systems face an inevitable slide into narrow herbal traditions and a loss of those elements of diagnosis and therapy which may be the most valuable and effective. Analyzing the case of Tibetan medicine and other Asian medical systems, I show how this process occurs and how it is resisted. I conclude by discussing the policy dimensions of this problem.
