Challenges of teaching corporate environmental management in Brazil

This paper sheds light on the main challenges of teaching Corporate Environmental Management (CEM) in Brazil. Thus, we analysed the main challenges for CEM in Brazil from the viewpoint of teachers. The objective of the research is achieved by means of interviews performed with five renowned professors responsible for teaching CEM in undergraduate courses. Results indicate five types of barriers for teaching CEM: weak integration of other teachers in the teaching of CEM; low level of acceptance of CEM as a subject by the peers teachers; a lack of focus on business while teaching CEM; a scarcity of CEM teaching materials appropriate for the realities of Brazil; and a relative lack of interest among some students in CEM. Teaching CEM is fundamental for the education of more responsible students, but little is known about teaching CEM in Brazil.. Copyright © 2013 Inderscience Enterprises Ltd.

Environmental management and operational performance in automotive companies in Brazil: The role of human resource management and lean manufacturing

The main objective of this study is to verify the influence of Environmental Management (EM) on Operational Performance (OP) in Brazilian automotive companies, analyzing whether Lean Manufacturing (LM) and Human Resources (HR) interfere in the greening of these companies. Therefore, a conceptual framework listing these concepts was proposed, and three research hypotheses were presented. A questionnaire was elaborated based on this theoretical background and sent to respondents occupying the highest positions in the production/operations areas of Brazilian automotive companies. The data, collected from 75 companies, were analyzed using structural equation modeling. The main results are as follows: (a) the model tested revealed an adequate goodness of fit, showing that overall, the relations proposed between EM and OP and between HR, LM and EM tend to be statistically valid; (b) EM tends to influence OP in a positive and statistically weak manner; (c) LM has a greater influence on EM when compared to the influence HR has over EM; (d) HR has a positive relationship over EM, but the statistical significance of this relationship is less than that of the other evaluated relationships. The originality of this paper lies in its gathering the concepts of EM, LM, HR and OP in a single study, as they generally tend not to be treated jointly. This paper also provided valid empirical evidence for a littlestudied context: the Brazilian automotive sector. © 2012 Elsevier Ltd. All rights reserved.

Efeito do manejo e de níveis de lodo de esgoto na fertilidade do solo após tres aplicações

The agricultural use of sewage sludge as organic fertilizer is considered nowadays as on alternative of disposal, in the end of the residue in addition to possible environmental problems, it's using can decrease the mineral fertilizers and avoid provide organic matter to the soil. The objective of this study it was to evaluate the parameters of soil fertility under different managements and doses of sewage sludge after the third application of the residue. The experiment was carried out in São Manuel - SP, with the cultivation of sunflower in two consecutives cycles, followed by wheat and triticale without application of the residual, and in the following year with the application of sewage sludge and cultivated the black oats. It was adopted a randomized complete block design, consisting of six treatments and five repetitions defined as follows: T0 - without fertilization; T1 - mineral fertilizer nitrogen according to crop need, T2 - 50% of N from sewage sludge and 50% in mineral form, T3 - 100% of N from sewage sludge, T4 - 150% of N from sewage sludge, T5 - 200% of N derived from sewage sludge. Soil samples were collected in the end of the trial of oats. There were an increase in the levels of P, H + Al, CEC and OM, B, Cu, Fe, Mn, Zn as a function of increasing dose of sewage sludge. To V% and pH were decreased the values in the proportional soil to the increase of sludge dose until 24 and 22 t ha-1, respectively and after increasing the pH and V%.

In Vitro Susceptibility of Environmental Isolates of Exophiala dermatitidis to Five Antifungal Drugs

Several dematiaceous fungi frequently isolated from nature are involved in cases of superficial lesions to lethal cerebral infections. Antifungal susceptibility data on environmental and clinical isolates are still sparse despite the advances in testing methods. The objective of this study was to examine the activities of 5-flucytosine, amphotericin B, itraconazole, voriconazole and terbinafine against environmental isolates of Exophiala strains by minimum inhibition concentration (MIC) determination. The strains were obtained from hydrocarbon-contaminated soil, ant cuticle and fungal pellets from the infrabuccal pocket of attine gynes. Broth microdilution assay using M38-A2 reference methodology for the five antifungal drugs and DNA sequencing for fungal identification were applied. Terbinafine was the most active drug against the tested strains. It was observed that amphotericin B was less effective, notably against Exophiala spinifera, also studied. High MICs of 5-flucytosine against Exophiala dermatitidis occurred. This finding highlights the relevance of studies on the antifungal resistance of these potential opportunistic species. Our results also contribute to a future improvement of the standard methods to access the drug efficacy currently applied to black fungi. © 2012 Springer Science+Business Media Dordrecht.

Enriquecimento alimentar e cognitivo para o bem-estar em cativeiro

Quando colocamos um animal em cativeiro, limitamos suas ações, assumindo o controle de boa parte das variáveis que atuam sobre um ambiente restrito. Essas variáveis, apesar de suprirem as necessidades básicas dos animais, tem o potencial de ser extremamente previsíveis e, por conseguinte, estressantes. Enriquecimento ambiental pode ser um dos mais importantes avanços na área de saúde animal em cativeiro nos últimos tempos, elevando os parâmetros psicológicos e fisiológicos de bem-estar, suprimidos pelo cativeiro. O principal objetivo deste trabalho foi criar e verificar a efetividade de um equipamento de enriquecimento ambiental denominado “roleta”, com a função de minimizar os efeitos danosos do cativeiro a dois macacos-prego, ao aumentar o tempo dedicado às atividades de forrageamento, aproximando seu orçamento de atividades àquele pertinente aos animais em vida livre. As observações foram realizadas pelo método de amostragem instantânea, em cinco etapas: 1) pré-intervenção, 2) D5, 3) D10, 4) D15 e 5) pós-intervenção, sendo, posteriormente, comparadas longitudinalmente. Os dados demonstram a efetividade da roleta como item enriquecedor do ambiente, uma vez que a frequência de comportamentos associados à exploração e deslocamento sofreu incremento ao longo das intervenções – com exceção à D10, que oportunamente será reavaliada – mantendo-se frequência média de forrageamento próxima ao esperado em animais de vida livre (Rímoli, 2001) ainda nas observações pós-intervenção, em detrimento da frequência de comportamentos considerados anormais ou estereotipados.
