This study analyzes the characteristics of publications on sustainability topics and education for sustainability in the Web of Science (WOS) database during the period ranging from 2005 to 2014. We identified the topics that are being studied within those subjects and other relevant topics. We also analyzed a special edition of the Journal of Cleaner Production on “Higher Education for Sustainable Development: Emerging areas,” published in January, 2014. Our approach was both qualitative and quantitative and aimed at qualifying and quantifying certain variables related to the scientific literature on the broad subject of sustainability. The number of published pieces in the WOS focusing on sustainability issues during the period from 2005 to 2014 was 5,924. In our analysis of the special edition of the Journal of Cleaner Production, we found and analyzed 17 abstracts and full papers. The main results of our survey highlight the education, educational research, environmental sciences, ecology, and engineering areas as including the greatest number of publications. Articles, as opposed to conference proceedings or reviews, accounted for 63% of the published documents, and the year 2013 showed the largest number of publications. Huisingh, Suciu, Katane, and Barth are the most published authors on these topics. Furthermore, management, environmental studies, ecology, and environmental sciences are the “hot topics” with the best search results, meaning articles of impact and high quality. Finally, it should be emphasized that publications on the subject of sustainability appear most often in the sciences.

The aim of this study was to identify the factors that influence in configuration of the technological capability of companies in sectors with medium-low technological intensity. To achieve the goal proposed in this article a survey was carried out. Based on the framework developed by Lall (1992) which classifies firms in basic, intermediate and advanced level of technological capability; it was found that the predominant technological capability is intermediate, with 83.7% of respondent companies (plastics companies in Brazil). It is believed that the main contribution of this study is the finding that the dependent variable named "Technological Capability" can be explained at a rate of 65% by six variables: development of new processes; selection of the best equipment supplier; sales of internally developed new technology to third parties; design and manufacture of equipment; study of the work methods and perform inventory control; and improvement of product quality.

Analysis of blood and lymphatic vessel in colorectal cancer is controversial in the literature, possibly due to variations in the methods of analysis. In this study, it was aimed to search for a reliable approach in the quantification of angio- and lymphangiovascular density and area as a prognostic factor and to compare such vessel counts in normal mucosa, adenomas and cancer. A retrospective study was performed on 60 sporadic colorectal cancer, 30 colorectal adenomas, and 10 colorectal non-neoplastic lesions. Archival tissues were submitted to immunohistochemical evaluation using antibodies to CD31, CD34, CD105, VEGF-A, VEGF-C, and D2-40. Microvessel density and total vascular area were determined by computer image analysis and values were compared in the three groups of lesions; the prognostic value of these parameters was evaluated in the group of colorectal cancer. Most markers showed progressive vessel counts from non-neoplastic tissue to carcinoma, both for microvessel density and total vascular area. Only microvessel density determined by CD34 in the central areas of the cancer correlated with recurrence/metastasis (p = 0.04) and survival (p = 0.02). Different methods of quantification (microvessel counting versus estimation of total vascular area), immunohistochemical markers (pan-endothelial marker versus neovessels and lymphatic markers), and areas of analysis (periphery versus inner portions of the lesion) were assessed using image analysis. The results corroborate the increase in vascularization of carcinoma and suggest that microvessel density determined by immunostaining for CD34 in the inner portion of the tumor might represent a prognostically relevant parameter in colorectal cancer.

RESUMOA Logística Reversa (LR) é um tema relativamente recente nos estudos acadêmicos e teve no Brasil seu maior destaque a partir da Política Nacional de Resíduos Sólidos. Este artigo tem o objetivo de verificar, em 47 artigos da base SPELL publicados entre o ano de 2003 e setembro de 2015, como tem sido estudada a LR. Observou-se que os pesquisadores parecem ter restrições em se debruçar sobre a LR nas questões diárias de consumo (como, por exemplo, o descarte de óleo lubrificante para veículos, lâmpadas, vidro, plástico e embalagens). Concluiu-se que a Logística Reversa ainda pode ser mais amplamente explorada, uma vez que há diversidades e especificidades nos setores, funções e fluxos envolvidos. Futuros estudos podem abordar mais temas, assim como o impacto da legislação brasileira e também ações em prol de uma Logística Reversa verde e ecoeficiente.

The aim of this study was to investigate whether the AgNOR technique could be helpful for the cytologic diagnosis of neoplastic and non-neoplastic urinary tract lesions. We analysed the AgNOR pattern in urinary cytology in samples from 70 patients. In every case the average number of silver precipitations per nucleus was counted and the range between the minimum and maximum AgNOR value calculated. Furthermore we noted whether the AgNOR precipitations had a homogeneous or heterogeneous distribution. The diseases were classified in three groups: non-neoplastic lesions, low grade and high grade carcinoma. Linear discriminant analysis (with jack-knife procedure) was performed with the AgNOR parameters as independent variables. The final diagnosis of each patient had been established by histological analysis of bladder biopsies. We obtained a correct classification in 84.3% of the cases. All patients with normal or reactive lesions were correctly classified and only two cases of low grade malignancy were erroneously diagnosed as non-malignant. Five high grade neoplasms had been classified as low grade and four low grade carcinomas had been over-diagnosed as high grade neoplasms. We conclude that a combined qualitative and quantitative AgNOR analysis can be useful in the differential diagnosis of urinary cytology.

-33 - RESUMoO termo "alienação" é usado em análises sociológicas dos sistemas produtivos (alienação no trabalho) e, recentemente, em estudos sobre consumo compulsivo. Não se identificou, entretanto, definição ou investigações discutindo "alienação no descarte" de produtos e embalagens. Nesse contexto, o intuito deste artigo é identificar a percepção das pessoas sobre implicações do ato de descartar um produto ou uma embalagem. Para isso, realizaram-se entrevistas com cidadãos e especialistas na área socioambiental em Porto Alegre, Brasil, mediante roteiros semiestruturados, abordando questões gerais sobre meio ambiente, comportamento de compra, hábitos e atitudes relacionados ao descarte e destino de produtos e embalagens. Os resultados apontam uma falta de conhecimento sobre o ciclo de vida das embalagens e dos produtos. O consumidor, durante a compra, não leva em conta que deverá descartar a embalagem e, posteriormente, o produto. O descarte é associado ao ato de "fazer sumir da frente dos olhos", sendo visto como uma atribuição dos órgãos de limpeza urbana, eximindo, assim, o consumidor de qualquer responsabilidade sobre as etapas posteriores ao descarte. Os resultados desta investigação poderão subsidiar iniciativas à conscientização socioambiental da população, bem como à elaboração de políticas para informações sobre produtos e responsabilidades dos consumidores.Palavras-chave: consumo, alienação, descarte, consciência ambiental.
