Economic Analysis of Knowledge: The History of Thought and the Central Themes

Following the development of knowledge economies, there has been a rapid expansion of economic analysis of knowledge, both in the context of technological knowledge in particular and the decision theory in general. This paper surveys this literature by identifying the main themes and contributions and outlines the future prospects of the discipline. The wide scope of knowledge related questions in terms of applicability and alternative approaches has led to the fragmentation of research. Nevertheless, one can identify a continuing tradition which analyses various aspects of the generation, dissemination and use of knowledge in the economy

"A wild and wondrous ride": CDC field epidemiologists in the east Pakistan smallpox and cholera epidemics of 1958 "Uma louca e maravilhosa jornada": epidemiologistas de campo do CDC nas epidemias de varíola e cólera do Paquistão Oriental em 1958

In mid-April of 1958 the Government of Pakistan summoned the press to announce a grave need for international aid to cope with smallpox and cholera epidemics in East Pakistan. In response, and with the backing of the US State Department, Dr. Alexander D. Langmuir, chief epidemiologist of the CDC, led a team of epidemiologists to assist authorities in Dacca strengthen their immunization programs. Langmuir's superiors hoped for a Cold War advantage, but he saw an opportunity for trainees in the Epidemic Intelligence Service to learn about public health in a developing country. Langmuir later described the episode as a "wild and wondrous ride," but it had been more like a nightmare: the East Pakistan health department had collapsed; a popular movement had taken over vaccination and squandered vaccine supplies; hostile journalists had questioned the Americans' deeper motives; and a professional rivalry opened between the Americans and a British epidemiologist named Aidan Cockburn. By the time the epidemic subsided in July 1958, 30 million Bengalis had been vaccinated for smallpox but another 20,000 had succumbed to the disease. This episode was CDC's first sustained foreign intervention, a precursor to its extensive role in the 1970s helping WHO eradicate smallpox from Bangladesh.<br>Em meados de abril de 1958, o Governo do Paquistão convocou a imprensa para anunciar a urgente necessidade de auxílio internacional para lidar com epidemias de varíola e cólera no Paquistão Oriental. Em resposta, e com o apoio do Departamento de Estado dos Estados Unidos, Dr. Alexander D. Langmuir, chefe de epidemiologia do CDC em Atlanta, liderou um time de epidemiologistas para auxiliar as autoridades em Dacca a reforçar seus programas de imunização. Os superiores de Langmuir ansiavam por demonstrações de capacidade dos EUA na Guerra Fria, mas ele vislumbrou uma chance para o Serviço de Inteligência Epidemiológica aprender sobre saúde pública em países em desenvolvimento. Langmuir descreveu o episódio como uma "jornada louca e maravilhosa", porém pareceu mais um pesadelo: o departamento de saúde do Paquistão Oriental entrou em colapso; um movimento popular assumiu a vacinação e desperdiçou suprimentos de vacinas; jornalistas hostis questionaram as motivações ocultas dos americanos; e iniciou-se uma rivalidade profissional entre americanos e o epidemiologista britânico Aidan Cockburn. No final da epidemia, em julho de 1958, tinham sido vacinados trinta milhões de bengalis contra varíola, mas outros vinte mil sucumbiram. Esse episódio foi a primeira intervenção sistemática do CDC no exterior

Rural Mental Health Ecology: A Framework for Engaging with Mental Health Social Capital in Rural Communities

The mental health of people in rural communities is influenced by the robustness of the mental health ecosystem within each community. Theoretical approaches such as social ecology and social capital are useful when applied to the practical context of promoting environmental conditions which maximise mental health helping capital to enhance resilience and reduce vulnerably as a buffer for mental illness. This paper explores the ecological conditions that affect the mental health and illness of people in rural communities. It proposes a new mental health social ecology framework that makes full use of the locally available unique social capital that is sufficiently flexible to facilitate mental health helping capital best suited to mental health service delivery for rural people in an Australian context
