Vitamin A Deficiency and Training to Farmers: Evidence from a Field Experiment in Mozambique

Vitamin A deficiency is a widespread public health problem in Sub-Saharan Africa. This paper analyzes the impact of a food-based intervention to fight vitamin A deficiency using orange-fleshed sweet potato (OFSP). We conducted a randomized evaluation of OFSP-related training to female farmers in Mozambique, in which the treatment group was taught basic concepts of nutrition, and OFSP-planting and cooking skills. We found encouraging evidence of changes in behavior and attitudes towards OFSP consumption and planting, and considerable increases in nutrition-related knowledge, as well as knowledge on cooking and planting OFSP.

Migrant Remittances and Information Flows: Evidence from a Field Experiment*

Do information flows matter for remittance behavior? We design and implement a randomized control trial to quantitatively assess the role of communication between migrants and their contacts abroad on the extent and value of remittance flows. In the experiment, a random sample of 1,500 migrants residing in Ireland was offered the possibility of contacting their networks outside the host country for free over a varying number of months. We find a sizable, positive impact of our intervention on the value of migrant remittances sent. Our results exclude that the remittance effect we identify is a simple substitution effect. Instead, our analysis points to this effect being a likely result of improved information via factors such as better migrant control over remittance use, enhanced trust in remittance channels due to experience sharing, or increased remittance recipients’ social pressure on migrants.

Análise comparativa do direito de acesso a cuidados de saúde no serviço nacional de saúde português e sistema de saúde norte-americano (EUA)

RESUMO - O presente estudo situa-se nas áreas gerais da Saúde Pública, dos Sistemas de Saúde e do Acesso à Prestação de Cuidados de Saúde e procura analisar o conteúdo e concretização do Direito de Acesso a Cuidados de Saúde na perspectiva de dois sistemas de saúde paradigmaticamente distintos, um sistema de acesso universal, representado pelo Serviço Nacional de Saúde português e um sistema de saúde de “não universal”, cujo paradigma é o modelo existente nos Estados Unidos da América, onde entidades gestoras de cuidados, Managed Care Organizations, são chamadas a desempenhar um papel central no acesso e prestação de cuidados de saúde. O vasto campo de investigação representado pela problemática do acesso a cuidados de saúde e a necessidade de limitar o trabalho de investigação subjazem à definição de quatro vertentes a analisar: (a) a existência ou não de uma base legal que preveja e regule o exercício do direito de acesso a cuidados de saúde; (b) o conteúdo deste direito no âmbito de cada um dos sistemas em estudo; (c) as condições de concretização do acesso a cuidados de saúde em ambos os sistemas, e, por último (d) a existência de garantias de efectivação do mesmo. Analisados os sistemas em estudo à luz das vertentes apresentadas, concluímos que a existência de um quadro normativo próprio, que explicite o conteúdo e condições de efectivação do direito, apresenta maiores garantias de concretização do exercício do Direito de Acesso a Cuidados de Saúde, entendendo-se que um sistema de acesso dependente da actuação de entidades gestoras de cuidados não beneficia o acesso a cuidados de saúde, nomeadamente por não garantir equidade no momento de procura e necessidade de cuidados. Os dados apresentados foram recolhidos através do recurso a uma metodologia qualitativa. A análise documental foi aplicada na recolha dos dados relativos à evolução e caracterização dos sistemas, bem como às condições de acesso. No âmbito do sistema de saúde de acesso universal, ou seja, o caso português, procedeu-se essencialmente à análise dos normativos aplicáveis. No que se refere ao sistema de saúde norte-americano, na ausência de base legal aplicável, recorreu-se sobretudo à análise de literatura e documentos. A participação no vi Second Biennal Seminar in Law and Bioethics1 e na 30th Annual Health Law Professors Conference2, realizados em Bóston, EUA, em Julho de 2007, permitiram uma melhor percepção da actual situação da prestação de cuidados naquele País, nomeadamente de algumas das reformas em curso, bem como um melhor entendimento das características do sistema prestador norte-americano em si mesmo. 1 Seminário organizado nos dias 30 e 31 de Maio, numa colaboração entre a Escola Nacional de Saúde Pública e o Departamento de Direito da saúde, Bioética e Direitos Humanos da Escola de Saúde Pública da Universidade de Bóston, sob o tema: “Law and ethics in rationing Access to care in a high-cost global economy”. A nossa participação deveu-se a um convite da Prof.ª Paula Lobato de Faria para colaborar na sessão sobre o sistema de saúde português. 2 Reunião realizada em Bóston nos dias 31 de Maio a 2 de Junho, sobretudo a sessão dedicada ao tema “New Models for Reform”, sobre os novos modelos de sistema de saúde em desenvolvimento nos EUA.

Automatic delimitation of the clinical region of interest in ultra-wide field of view images of the retina

Retinal ultra-wide field of view images (fundus images) provides the visu-alization of a large part of the retina though, artifacts may appear in those images. Eyelashes and eyelids often cover the clinical region of interest and worse, eye-lashes can be mistaken with arteries and/or veins when those images are put through automatic diagnosis or segmentation software creating, in those cases, the appearance of false positives results. Correcting this problem, the first step in the development of qualified auto-matic diseases diagnosis programs can be done and in that way the development of an objective tool to assess diseases eradicating the human error from those processes can also be achieved. In this work the development of a tool that automatically delimitates the clinical region of interest is proposed by retrieving features from the images that will be analyzed by an automatic classifier. This automatic classifier will evaluate the information and will decide which part of the image is of interest and which part contains artifacts. The results were validated by implementing a software in C# language and validated through a statistical analysis. From those results it was confirmed that the methodology presented is capable of detecting artifacts and selecting the clin-ical region of interest in fundus images of the retina.
