New and existing companies are looking for ways to thrive in a competitive environment with innovative business models while respecting society and avoiding actions that harm the planet. Trends such as circular economy, fair trade, lowsumerism, and sharing economy are some of the many emerging entrepreneurial approaches that address this issue, but there is still a gap between what theory argues and the levels of environmental and social sustainability realized when theory is put into practice. In fact, most research on the topic of sustainable business models is still exploratory and does not fully acknowledge these emerging approaches, whose definitions, boundaries, and defining characteristics are still somewhat vague. This study seeks to contribute to the understanding of the inner entrepreneurial dynamics of innovative sustainable business models. In particular, we focus on the fashion business, a resource-intensive industry in which opportunities to reduce environmental impacts and to innovate business models abound. The aim of our research is to investigate innovative business models in the fashion industry that have sustainability as their defining characteristic, especially in terms of value proposition. In order to do that, we combine a systematic review of the literature with empirical research comprised of six interviews with specialists in sustainability, business model innovation, and the fashion industry, along with eight case studies on innovative fashion startups we define as 'born sustainable.' As a result, we propose a synthesizing framework that discloses trends and drivers of innovative and sustainable business models in the fashion industry. We also highlight opportunities and challenges for researchers and entrepreneurs interested in this topic.
Foot and mouth disease (FMD) is a highly infectious disease that affects cloven-hoofed livestock and wildlife. FMD has been a problem for decades, which has led to various measures to control, eradicate and prevent FMD by National Veterinary Services worldwide. Currently, the identification of areas that are at risk of FMD virus incursion and spread is a priority for FMD target surveillance after FMD is eradicated from a given country or region. In our study, a knowledge-driven spatial model was built to identify risk areas for FMD occurrence and to evaluate FMD surveillance performance in Rio Grande do Sul state, Brazil. For this purpose, multi-criteria decision analysis was used as a tool to seek multiple and conflicting criteria to determine a preferred course of action. Thirteen South American experts analyzed 18 variables associated with FMD introduction and dissemination pathways in Rio Grande do Sul. As a result, FMD higher risk areas were identified at international borders and in the central region of the state. The final model was expressed as a raster surface. The predictive ability of the model assessed by comparing, for each cell of the raster surface, the computed model risk scores with a binary variable representing the presence or absence of an FMD outbreak in that cell during the period 1985 to 2015. Current FMD surveillance performance was assessed, and recommendations were made to improve surveillance activities in critical areas.
RESUMO: Avaliaram-se os resultados de testes para diagnóstico da brucelose e tuberculose bovinas objetivando analisar a distribuição de positividade e características de performance do programa de controle. A análise utilizou como dados secundários todos os resultados de testes para diagnóstico realizados em bovinos no ano de 2008 no estado do Rio Grande do Sul (RS) por médicos veterinários habilitados para atuação no âmbito do Programa Nacional de Controle e Erradicação de Brucelose e Tuberculose Animal. Os dados foram estatisticamente ajustados para minimizar os efeitos de valores extremos e de dados faltantes. Os testes alcançaram 66,80% dos 497 municípios do RS e incluíram a participação de 165 médicos veterinários habilitados. 40,21% dos testes foram realizados nos meses de abril, setembro e outubro, sendo que em 73,90% dos estabelecimentos foram realizados testes para ambas as enfermidades. No caso da brucelose verificou-se que foram testados 35.289 animais, com uma frequência de positivos de 0,25%, enquanto a frequência de estabelecimentos positivos entre os 3.406 testados foi 0,94%. Fêmeas apresentaram frequência de positividade mais elevada (0,29%, de 26.724 testadas) do que machos (0,13%, de 5.235 testados). Animais entre 48-60 meses de idade apresentaram chance de positividade superior às demais faixas etárias (Razão de Chances (RC) =2,63; IC 95%=1,63-4,26). Animais de aptidão leiteira representaram 62,66% dos animais testados, e apresentaram maior chance de positividade do que animais de corte (RC=2,32; IC 95%=1,38-3,90). Adicionalmente, 73,74% dos estabelecimentos testados eram dedicados à produção de leite. Já no caso da tuberculose foram testados 62.149 animais distribuídos em 5.151 propriedades, com frequência de positivos de 0,87% e 3,13%, respectivamente. A chance de positividade aumentou com a idade, sendo que animais com idade acima de 48 meses de idades apresentaram valores superiores aqueles verificados em animais mais jovens (RC=2,07; IC 95%=1,73-2,48). 59,74% dos animais testados eram de aptidão leiteira, os quais apresentaram mais chance de serem positivos do que aqueles de corte (RC=5,03; IC 95%=4,09-6,94). Propriedades leiteiras representaram 78,50% da totalidade dos testes para tuberculose. A análise comparativa do presente trabalho com estudos precedentes de prevalência da brucelose sugere que as ações de controle em curso têm sido efetivas na redução da prevalência da enfermidade no RS. Por outro lado, as informações obtidas no âmbito da tuberculose podem ser indicadoras da condição desta enfermidade, especialmente pela inexistência de estudos de prevalência realizados há menos de 30 anos. Adicionalmente, conclui-se que a utilização de dados secundários, desde que devidamente ajustados, pode ser uma ferramenta eficaz na gestão de programas de saúde animal e em sistemas de monitoramento e vigilância.
Risks of the introduction of highly pathogenic avian influenza (HPAI) H5N1 through migratory birds to the main wintering site for wild birds in southern Brazil and its consequences were assessed. Likelihoods were estimated by a qualitative scale ranging from negligible to high. Northern migrants that breed in Alaska and regularly migrate to South America (primary Charadriiformes) can have contact with birds from affected areas in Asia. The likelihood of the introduction of HPAI H5N1 through migratory birds was found to be very low as it is a probability conditioned to successful transmission in breeding areas and the probabilities of an infected bird migrating and shedding the virus as far as southern Brazil. The probability of wild species becoming exposed to H5N1-infected birds is high as they nest with northern migrants from Alaska, whereas for backyard poultry it is moderate to high depending on proximity to wetlands and the presence of species that could increase the likelihood of contact with wild birds such as domestic duck. The magnitude of the biological and economic consequences of successful transmission to poultry or wild birds would be low to severe depending on the probability of the occurrence of outbreak scenarios described. As a result, the risk estimate is greater than negligible, and HPAI H5N1 prevention strategy in the region should always be carefully considered by the veterinary services in Brazil.
Pesq. Vet. Bras. 34(6):542-554, junho 2014 542 RESUMO.-O serviço veterinário oficial é responsável por proteger a saúde pública e animal, assegurando a oferta de produtos de origem animal inócuos aos consumidores. Uma ferramenta que auxilia na busca desses objetivos é a análise de risco, que iniciou a ser utilizada na segunda metade da década de 90 pelos serviços veterinários oficiais dos países. Para a realização de uma análise de risco, qualitativa ou quantitativa, inicialmente deve-se identificar o perigo, a qual na área da saúde animal geralmente é o agente patogênico causador de uma doença. A etapa subsequente The official veterinary service is responsible for protecting public and animal health, certifying the supply of safe animal products to consumers. A tool that assists in the pursuit of these goals is the risk analysis, which began to be used in the second half of the 1990s for the official veterinary services of countries. To carry out a risk analysis, qualitative or quantitative, one must initially identify the danger, which in the area of animal health is usually the pathogen causing a disease. The subsequent step is risk assessment, which must be analyzed, supported by scientific studies or experts in the field, the possible ways of introduction, exposition and maintenance of the pathogen in the susceptible population, as well biological, economic, political and social consequences. The third step in the analysis of risk refers to risk management, which aims to propose measures to mitigate the risk to the desired level, and assess the cost/benefit of each measure. The last phase of a risk analysis is risk communication. This step is critical for success of the study and should be initiated along with risk analysis itself, always leaving open a permanent communication with all social actors interested in risk analysis. Risk analysis has become an important tool used by managers of the official veterinary services in decision-making, contributing to the choice of alternatives that give scientifically the lowest animal health risk. This study conducted a review of the literature on risk analysis aimed to expose its definition and development process, as well as to see how it is being used and what limitations and challenges of using this tool by the Brazilian national veterinary service.
RESUMO Avaliaram-se os dados do controle e monitoramento de Salmonella em carcaças de frangos de corte, antes e após a implantação do sistema de lavagem de carcaças. Foram amostradas 2692 carcaças antes da instalação do sistema e 1940 após a instalação, totalizando 4632 amostras em cinco abatedouros sob Inspeção Federal, no sul do Brasil. Anteriormente à instalação dos lavadores, obtiveram-se 156 resultados positivos para Salmonella spp. e, após a instalação, 83 resultados positivos, com diferença significativa (P<0,05/OR 1,4) entre os resultados gerais. Em dois dos cinco abatedouros avaliados, houve redução na positividade para Salmonella spp. nas carcaças amostradas após a instalação do lavador. Entretanto, em três estabelecimentos não houve diferença significativa após a instalação desse sistema. Os resultados sugerem que o aumento da vazão da água está relacionado com a redução da contaminação, enquanto o aumento da pressão de água do sistema de lavagem não foi suficiente para reduzir o patógeno nas carcaças amostradas. Dessa forma, conclui-se que o sistema de lavagem tem vantagens do ponto de vista operacional, ao evitar os desperdícios atribuídos à prática do refile, porém não elimina o risco da presença de Salmonella na carcaça de frango.
