ResumoObjetivou-se desenvolver e validar um instrumento adequado para avaliar o impacto de um programa piloto de intervenção no ambiente alimentar local para promoção da alimentação saudável em comércios de varejo de alimentos da Zona Noroeste em Santos/SP, região caracterizada como deserto alimentar. Foi realizada pesquisa formativa para validação do instrumento, incluindo reuniões de pesquisadores, varredura no território estudado para identificação dos comércios de alimentos, visitas a atores do canal de distribuição de alimentos, oficinas comunitárias com a comunidade local e entrevistas em profundidade com proprietários dos estabelecimentos para validação de conteúdo e validade aparente. Foi testada confiabilidade do instrumento por coeficiente de alfa de Cronbach. O desenvolvimento do questionário incluiu questões para avaliação da Identificação e Caracterização do Comércio; Parâmetros de Comercialização, incluindo importância de fatores para a inclusão de um novo alimento, frequência de aquisição de produtos, rentabilidade; e Escala de Fatores Psicossociais, incluindo expectativa em relação às vendas de alimentos saudáveis, expectativa em relação ao impacto, e autoeficácia em relação à comercialização de alimentos saudáveis. A validação permitiu revisão de todas as questões e alternativas de resposta do questionário, com alfa de Cronbach variante de 0,440 a 0,967 nas questões do instrumento final. Este resultado indica que o instrumento proposto foi capaz de identificar características relevantes do sistema de distribuição de alimentos á nível local e pode ser utilizado em estudos epidemiológicos para avaliação de políticas públicas territoriais elaboradas para aumento do acesso a alimentos saudáveis.Palavras-chave: Estudos de Validação; Saúde da População Urbana; Ambiente Alimentar AbstractThe objective was to develop and validate a culturally appropriate instrument to evaluate the impact of a pilot intervention program in the food environment to promote healthy eating in small food stores in an urban food desert. A formative research was carried out for the validation of the instrument, including meetings of researchers, visits to all the streets in the study's region to identify food stores, visits to food distribution system agents', community workshops with the local community and in-depth interviews with food store owners for content and apparent validity. Instrument reliability was tested by Cronbach alpha coefficient. The development of the instrument included questions to evaluate the Identification and Characterization of Store; Marketing Parameters (i.e. influencers for including new food itens and frequency of product acquisition and profitability); and Psychosocial Factors Scale (i.e. expectations regarding healthy food sales, expectations regarding impact of intervention, and self-efficacy in relation to the marketing of healthy foods). Validation process allowed a review of all questions and questions' responses, with Cronbach alpha between 0.440 to 0.967 in the final instrument questions. It can be concluded that the instrument was developed to identify relevant characteristics of the food distribution system and can be used in epidemiological studies and public policies to evaluate increase access to healthy foods.Key words:Validation Studies; Urban Health; Food Environment

SIDA (Intelligent Food Distribution System, for its acronym in Spanish) is a proposed tool for the distribution of food that can be personalized depending on the medical characteristics of each patient. The target of the tool is to provide foods that contain higher nutrients in the diet set by a hospital. A model of decision trees was based on data from the organization of the United Nations Food and Agriculture Organization (FAO) and used for decision making in the simulated three basic foods based on the diet of Latin American countries typically integrated by rice, potatoes, and lentils from the parameters of fat, energy, and protein, respectively, that contains every type of food.

In May, 1980, when the Geneva meeting on Humani tarian Assistance and Relief to the Kampuchean People took place and funds to continue aid were pledged, the food distribution system inside Kampuchea was a sham bles. Rice-laden ships were backed up in the harbors at Kampong Som and Pnompenh, where warehouses were full. Rice, unlike rice seed, was not reaching the villages.There was rare consensus on this point, even among those international organizations and voluntary agencies that had been presenting a generally positive pic ture of developments inside Kampuchea. Relief work ers in Pnompenh took the unprecedented step of jointly warning the Heng Samrin regime that it could not count on continued international aid unless distribu tion improved. Interviews with Khmer peasants treking on foot, by bicycle, and oxcart to the Thai border from several provinces in west and northwest Kampuchea confirmed that food distribution was grossly inadequate if it existed at all. Heng Samrin's own village commit tees, with no rice to give peasants and farmers, were issuing passes to the Thai border that were being hon ored by the Vietnamese soldiers who control much of the access to the relief “land bridge” at Nong Chan.

The traditional food distribution system is often characterized by small farmers and of several retailer called middlemen who sell their products on market. Since the intermediaries and their market powers are largely considerable in the food market, this paper proposes an industrial organization model of the middlemen in this conventional food distribution system for developing countries. Since most of the works in this field has adopted an empirical approach, the focus of our study in this paper will be instead on theoretical model. In order to analyze this situation, we borrow several arguments from the theory of imperfect competition. We assume that middlemen have oliopsony and oligopoly power in the up and down stream of the food system. We defined the consumer behavior by discrete choice model and study the quantity flow from small producers to the consumers by mean of Cournot competition. We address the question of land reform policy implication by creating a productivity shock in order to examine the effect of this instrument on the wealth of both farmers and consumers.

In today's business environment, as the competitiveness becomes increasingly fierce, improving the business performance becomes more important. A major factor affecting business operations is distribution systems performance control. In a distribution network, if an independent point well manages its performance, the efficiency of the entire enterprise will improve. In order to do this, it is essential to evaluate the effectiveness of each distribution point. However, at present, this evaluation is usually based on experience or only a few indicators such as revenue or profit. The effectiveness of a distribution point should be simultaneously considered for sales with resources used such as costs, manpower or business market characteristics such as the number of similar stores within 4 kilometers radius... Therefore, DEA (Data Envelopment Analysis) method is proposed and used to evaluate the performance of independent distribution points and analyze the factors that affect efficiency by the Tobit regression model. This model was tested for a food distribution system in Ho Chi Minh City to prove its feasibility and usefulness.
