O programa de incentivo à instalação de cozinhas comunitárias: avaliação de uma política pública brasileira

O trabalho tem como objetivo descrever e avaliar as Cozinhas Comunitárias (CC) apoiadas pelo Ministério do Desenvolvimento Social (MDS) em funcionamento no Brasil em 2006. Trata-se de estudo transversal que investigou as CC, com projetos contemplados nos editais do MDS realizados entre os anos de 2003 a 2005. Inicialmente foram identificadas as CC em funcionamento e estas CC foram visitadas para a coleta de dados relativos ao atendimento prestado, avaliação da estrutura física e das refeições oferecidas. A estrutura física foi avaliada por meio de um check-list, baseado nas exigências da legislação sanitária, e a oferta de refeições foi caracterizada pelos alimentos e preparações oferecidas pelas CC para determinar o valor nutricional das refeições. A maioria das cozinhas financiadas (60%) estava em fase de implementação no momento da entrevista, entre as cozinhas em funcionamento, a maioria estava localizada nos Estados de Santa Catarina e Paraná. Observou-se também que cerca de 20% das cozinhas não ofereciam refeições regularmente. Ao realizar a avaliação nutricional das refeições, foi observada uma grande heterogeneidade na oferta de alimentos. Ao avaliar as condições higiênico-sanitárias, quase a totalidade das CC foram classificadas como deficientes ou regulares, indicando inadequação na produção de refeições. O Programa das Cozinhas Comunitárias pode exercer importante papel nas políticas de segurança alimentar e nutricional do país, no entanto, devem ser realizados esforços no sentido de garantir a implantação em comunidades situadas nos Estados menos desenvolvidos, com fixação de números mínimos para atendimento, de parâmetros nutricionais e garantia de fornecimento seguro de alimentos

Antecedentes do relacionamento e da performance em empresas da cadeia de suprimentos: estruturação e aplicação de modelos de equações estruturais

The relationship between companies is an important issue in the management of supply chains. Several aspects relating to the flow and exchange of information along the chain are considered as having a decisive influence on the success of this relationship. The main objective of this work was to structured and test models that link aspects of this nature with performance and the purchaser-supplier relationship in the supply chain. Aspects relevant to communication and the use do IT in relationships between companies were investigated. The importance of performance in this relationship was also investigated. The research were based on empirical data obtained by means of structural equation modeling. The results show that some aspects contribute in a significant way to the success of this relationship while others that, a priori, are considered important make no contribution.

Logistics information systems adoption: an empirical investigation in Brazil

Purpose - The purpose of this paper is to examine whether the level of logistics information systems (LIS) adoption in manufacturing companies is influenced by organizational profile variables, such as the company`s size, the nature of its operations and their subsectors. Design/methodology/approach - A review of the mainstream literature on US was carried out to identify the factors influencing the adoption of such information systems and also some research gaps. The empirical study`s strategy is based on a survey research in Brazilian manufacturing firms from the capital goods industry. Data collected were analyzed through Kruskall-Wallis and Mann Whitney`s non-parametric tests. Findings - The analysis indicates that characteristics such as the size of companies and the nature of their operations influence the levels of LIS adoption, whilst comparisons regarding the subsectors appeared to be of little influence. Originality/value - This is the first known study to examine the influence of organizational profiles such as size, nature of operations and subsector on the level of US adoption in manufacturing companies. Moreover, it is unique in portraying the Brazilian scenario on this topic and addressing the adoption of seven types of LIS in a single study.

Development, prevention and treatment of iron deficiency in women

Iron deficiency is the most common nutritional deficiency in the world. Women of childbearing age are at particular risk of developing iron deficiency due to the iron losses associated with menstruation and childbirth. Women in less developed countries are often unable to obtain adequate dietary iron for their needs due to poor food supplies and inadequate bioavailable iron. In this situation, fortification and supplementation of the diet with extra iron is a reasonable approach to the prevention and treatment of iron deficiency. In Western countries however, food supply is unlikely to be an issue in the development of iron deficiency, yet studies have shown that many women in these countries receive inadequate dietary iron. Research has shown that the form of iron and the role of enhancers and inhibitors of iron absorption may be more important than total iron intake in determining iron status. Despite this, very little research attention has been paid to the role of diet in the prevention and treatment of iron deficiency. Dietary modification would appear to be a viable option for the prevention and treatment of iron deficiency in Western women, especially if the effects of enhancers/inhibitors of absorption are considered. While dietary modification has the potential to address at least part of the cause of iron deficiency in women of childbearing age, its efficacy is yet to be proven. (C) 1998 Elsevier Science Inc.

RFID adoption: framework and survey in large Brazilian companies

Purpose - The purpose of this paper is to provide a framework for radio frequency identification (RFID) technology adoption considering company size and five dimensions of analysis: RFID applications, expected benefits business drivers or motivations barriers and inhibitors, and organizational factors. Design/methodology/approach - A framework for RFID adoption derived from literature and the practical experience on the subject is developed. This framework provides a conceptual basis for analyzing a survey conducted with 114 companies in Brazil. Findings - Many companies have been developing RFID initiatives in order to identify potential applications and map benefits associated with their implementation. The survey highlights the importance business drivers in the RFID implementation stage, and that companies implement RFID focusing on a few specific applications. However, there is a weak association between expected benefits and business challenges with the current level of RFID technology adoption in Brazil. Research limitations/implications - The paper is not exhaustive, since RFID adoption in Brazil is at early stages during the survey timeline. Originality/value - The main contribution of the paper is that it yields a framework for analyzing RFID technology adoption. The authors use this framework to analyze RFID adoption in Brazil, which proved to be a useful one for identifying key issues for technology adoption. The paper is useful to any researchers or practitioners who are focused on technology adoption, in particular, RFID technology.

Are supplier selection criteria going green? Case studies of companies in Brazil

Purpose - The purpose of this paper is to verify if Brazilian companies are adopting environmental requirements in the supplier selection process. Further, this paper intends to analyze whether there is a relation between the level of environmental management maturity and the inclusion of environmental criteria in the companies` selection of suppliers. Design/methodology/approach - A review of mainstream literature on environmental management, traditional criteria in the supplier selection process and the incorporation of environmental requirements in this context. The empirical study`s strategy is based on five Brazilian case studies with industrial companies. Face-to-face interviews and informal conversations are to be held, explanations made by e-mail with representatives from the purchasing, environmental management, logistics and other areas, and observation and the collection of company documents are also employed. Findings - Based on the cases, it is concluded that companies still use traditional criteria to select suppliers, such as quality and cost, and do not adopt environmental requirements in the supplier selection process in a uniform manner. Evidence found shows that the level of environmental management maturity influences the depth with which companies adopt environmental criteria when selecting suppliers. Thus, a company with more advanced environmental management adopts more formal procedures for selecting environmentally appropriate suppliers than others. Originality/value - This is the first known study to verify if Brazilian companies are adopting environmental requirements in the supplier selection process.

In the eye of the storm: exploring the introduction of environmental issues in the production function in Brazilian companies

This article aims to analyse the introduction of environmental issues in the context of the production function, which has been referred to as the organisational area to lead corporate environmental management. With that purpose, the theoretical references for corporate environmental management and the necessary alterations in production function have been organised to include environmental aspects, especially in terms of product and process development, quality management, and logistics. Considering that this research field still lacks empirical evidence for Brazilian companies, four case studies were conducted using companies located in the country. The environmental management maturity level of those companies tends to follow the rate with which the environmental issue is introduced in production sub-areas, especially in the product development process. However, in most cases we found that the companies had difficulties in structuring the insertion of the environmental dimension in logistics. The final notes point out the distance observed between what is recommended by international literature and the reality of Brazilian companies in the challenge of making the production function environmentally friendly.

Development of a digital hearing aid to meet the Brazilian Government`s Ordinance 587 (APAC) - Health Department

The treatment of sensorineural hearing loss is based on hearing aids, also known as individual sound amplification devices. The hearing aids purchased by the Brazilian Government, aiming at fulfilling public policies, are based on dedicated components, which bring about benefits, but also render them expensive and may impair repair services after manufacture`s warranty expires. Aim: to design digital behind-the-ear hearing aids built from standardized components coming from the very supply chain of these manufacturers. Study design: experimental. Materials and Methods: to identify the supply chain of these manufacturers, request samples and set up hearing aids in the laboratory. Results: The developed hearing aids did not show lesser electroacoustic characteristics when compared to those acquired by the Government, also being tested by the same reference international technical standard. Conclusion: It is possible to develop digital behind-the-ear hearing aids based on off-the-shelf components from hearing aid manufacturers` supply chain. Their advantages include low operational costs - for acquisition (with clear advantages for the Government) and service (advantage for the patient).

An evaluation of two indices of red fox (Vulpes vulpes) abundance in an arid environment

The suitability of spotlight counts to index red fox abundance was assessed in an arid environment through a comparison with a scat deposition index (active attractant). In most cases there was a high degree of correlation between the two indices, suggesting that the spotlight counts were accurately documenting fluctuations in population size. However, the precision of the spotlight index was often low (c.v. = 0.07-0.46), suggesting that the technique may not allow the statistical detection of small changes in abundance. During periods when there was an influx of new individuals into the population, the seasonal scat index displayed a three-month time lag in documenting abundance while foxes accustomed themselves to the presence of the regular food supply. The level of precision of the scat index was also found to be relatively low (c.v. = 0.21-0.48). Nevertheless, further refinements of this technique may produce a suitable measure of fox abundance.

An overview of APSIM, a model designed for farming systems simulation

The Agricultural Production Systems Simulator (APSIM) is a modular modelling framework that has been developed by the Agricultural Production Systems Research Unit in Australia. APSIM was developed to simulate biophysical process in farming systems, in particular where there is interest in the economic and ecological outcomes of management practice in the face of climatic risk. The paper outlines APSIM's structure and provides details of the concepts behind the different plant, soil and management modules. These modules include a diverse range of crops, pastures and trees, soil processes including water balance, N and P transformations, soil pH, erosion and a full range of management controls. Reports of APSIM testing in a diverse range of systems and environments are summarised. An example of model performance in a long-term cropping systems trial is provided. APSIM has been used in a broad range of applications, including support for on-farm decision making, farming systems design for production or resource management objectives, assessment of the value of seasonal climate forecasting, analysis of supply chain issues in agribusiness activities, development of waste management guidelines, risk assessment for government policy making and as a guide to research and education activity. An extensive citation list for these model testing and application studies is provided. Crown Copyright (C) 2002 Published by Elsevier Science B.V. All rights reserved.

Avanços logísticos no varejo nacional: o caso das redes de farmácias

O artigo descreve as conquistas realizadas na logística do varejo farmacêutico nacional nos últimos anos. As farmácias organizaram-se em redes; melhoraram seu aspecto visual; muitas operam 24 horas; usam fórmulas sofisticadas, teoricamente corretas, na gestão de estoques; dispõem de softwares avançados; operam depósitos racionalizados, por vezes automatizados; as entregas às lojas são diárias; o código de barras facilita o controle dos produtos. Subsistem problemas que impedem a obtenção de autêntico just in time e de falta-zero: dificuldade de prever a demanda; limitação da capacidade dos bancos de dados para registrar dados relativos a 5.000 apresentações em 100 lojas; entrosamento precário entre os setores de vendas e compras na empresa; freqüência e rapidez ainda insuficientes de reposição dos produtos no depósito e nas lojas; existência de numerosos medicamentos de baixo giro. Recomendações são apresentadas para a remoção desses entraves e o advento do sonhado Supply Chain Management.

Cadeia reversa do óleo de cozinha: coordenação, estrutura e aspectos relacionais

As atividades de produção e consumo geram resíduos que, conforme o destino, produzem impactos negativos no meio ambiente. Essa situação agravou-se, de maneira crítica, a partir da Revolução Industrial. Para reaproveitar esses resíduos, são necessárias novas formas de produzir, consumir e dar um destino adequado aos produtos após o final de seu ciclo de vida útil. Com base nesse contexto, o objetivo deste estudo é analisar como se estrutura e é coordenada uma cadeia de suprimentos reversa, tendo como objeto a coleta de óleo de cozinha utilizado. O caminho metodológico observa a abordagem qualitativa e caracteriza-se como exploratório. Em termos teóricos, o estudo orienta-se pelas abordagens de cadeias de suprimentos reversas e coordenação da cadeia de suprimentos. Os resultados evidenciam a iniciativa de uma empresa que não trabalha com óleo de cozinha utilizado, mas utiliza uma estratégia a partir desse resíduo para desencadear o processo de estruturação da cadeia analisada. Como principal contribuição, o estudo sugere a consolidação da quinta fase da logística: a Reverse Supply Chain (RSC).

RFID together with multi-agent systems to control global value chains

Nowadays, the cooperative intelligent transport systems are part of a largest system. Transportations are modal operations integrated in logistics and, logistics is the main process of the supply chain management. The supply chain strategic management as a simultaneous local and global value chain is a collaborative/cooperative organization of stakeholders, many times in co-opetition, to perform a service to the customers respecting the time, place, price and quality levels. The transportation, like other logistics operations must add value, which is achieved in this case through compression lead times and order fulfillments. The complex supplier's network and the distribution channels must be efficient and the integral visibility (monitoring and tracing) of supply chain is a significant source of competitive advantage. Nowadays, the competition is not discussed between companies but among supply chains. This paper aims to evidence the current and emerging manufacturing and logistics system challenges as a new field of opportunities for the automation and control systems research community. Furthermore, the paper forecasts the use of radio frequency identification (RFID) technologies integrated into an information and communication technologies (ICT) framework based on distributed artificial intelligence (DAI) supported by a multi-agent system (MAS), as the most value advantage of supply chain management (SCM) in a cooperative intelligent logistics systems. Logistical platforms (production or distribution) as nodes of added value of supplying and distribution networks are proposed as critical points of the visibility of the inventory, where these technological needs are more evident.

EDI e a fatura eletrónica redes colaborativas e desmaterialização

O Electronic Data Interchange (EDI) oferece um vasto leque de oportunidades para as empresas se tornarem mais competitivas. Não só na ótica dos processos de negócio de bens e serviços, como nas práticas organizacionais e de gestão. A adoção de tecnologias de informação e comunicação do comércio eletrónico B2B, visando o aumento da eficácia e eficiência na troca de documentos de negócio, possibilita a melhoria da colaboração entre agentes económicos de uma cadeia produtiva de bens ou serviços. O comércio eletrónico permitiu uma profunda transformação das práticas comerciais tradicionais, onde o EDI influenciou positivamente na forma de conduzir o negócio. Um conceito atualmente emergente é o de fatura eletrónica, essencial para o desenvolvimento da relação entre entidades (B2B). A desmaterialização da fatura acarreta inúmeros benefícios para as entidades envolvidas, tais como: a redução de custos, a redução do impacto ambiental e o aumento da produtividade e da transparência nos processos de negócio. Esta dissertação pretende abordar em detalhe as temáticas referentes ao EDI e à fatura eletrónica, no que concerne ao conceito, às mensagens, aos standards utilizados, aos benefícios e custos envolvidos, e a toda a sua envolvência ao longo de uma cadeia de abastecimento. Com base nestes conceitos, é apresentado um caso de estudo de sucesso na empresa nacional Sonae®, que pretende abordar todo o programa EDI da empresa. O esforço despendido na implementação do programa e na adoção da fatura eletrónica legal na Sonae® supera em larga escala os objetivos pretendidos, devido aos benefícios inerentes à utilização do EDI. A fatura eletrónica representa não só o conceito de troca de documentos via eletrónica, como também uma nova forma de conduzir os negócios.
