Processo de transferência de tecnologia da universidade para a indústria: estudo de caso envolvendo a conversão de glicerol

Currently, public policy has encouraged innovation in universities and also transference of technology to the industry. Another important stage to be considered would be the registration or filing of a patent and the economical viability study. Government programs, such as the innovation incentive program, among others, should facilitate popularization and promote interest by industry. In this work we described the steps, from the conception of the idea to the scale up going through its interest by the industry. The case study is about the glycerol conversion utilizing modified niobia as catalysts.

Seguros de desempleo: revisión de literatura y propuesta para Colombia

En este artículo se estudia la posibilidad de introducir seguros de desempleo en Colombia. En una primera parte, se propone una revisión de literatura de los seguros de desempleo en la cual se exponen las ventajas generadas por una cobertura contra este riesgo, así como sus inconvenientes. En una segunda parte, se estudian varios escenarios para introducir seguros de desempleo en Colombia. Después de haber presentado el contexto del mercado laboral y de las normas que lo vigilan, se proponen varios diseños que abordan la gestión y la administración del riesgo de desempleo en Colombia. Igualmente se presentan algunas consideraciones teóricas para la valoración del costo del aseguramiento, las cuales incorporan los efectos del riesgo moral sobre la duración y la incidencia del desempleo.

Grupo interdisciplinar: Construção de unidade educacional sistematizada em aprendizagem baseada em problemas

In 2003 the construction team of the 1st grade of the medical and nursing courses from a medical school began a work aiming at curriculum reconstruction, and restructured cognitive contents and the integration of basic and clinical aspects, in order to adapt to the incentive program for Curriculum Changes (PROMED) which allows for the continuity of curricular innovations. This team worked considering the group dynamics, a method already used in tutorial sessions which teachers have some familiarity with. For a good group performance the team participants were divided into two subgroups: one for constructing educational problems and the other for doing cognitive assessment exercises. The team and the subgroups met weekly, and every 15 days the group met for socialization of information, identifying the strengths and weaknesses of the process and/or products. A good adhesion, an active involvement of participants and satisfaction expressed by each participant with their inclusion in the group were reflected in the final product and contributed to the subjects' commitment to the proposal. This way, in the process the individual transformations and relations in a situation requiring the collaboration of professionals were essential in the process of permanent curricular reconstruction.

Economia solidária e política pública de geração de trabalho e renda – uma análise do Programa Bolsa Trabalho do estado do Pará

A dissertação intitulada “Economia solidária e política pública de geração de trabalho e renda: uma análise do Programa Bolsa Trabalho do Estado do Pará” traz contribuições à proposta de incluir social e economicamente jovens trabalhadores excluídos do mercado formal de trabalho a partir de uma estratégia política que articulou economia solidária, geração de trabalho e renda e incentivo financeiro temporário e condicionado. A pesquisa foi desenvolvida com base na experiência do referido Programa, realizado no período de 2007 a 2010, enquanto proposta de governo que compôs a Política Pública de Trabalho e Renda do Estado, sinalizando para construção de estratégias possíveis no combate ao desemprego, à pobreza, à exclusão social, especialmente da população jovem, a partir da economia solidária. O Programa Bolsa Trabalho foi estruturado em três eixos de qualificação social e profissional, a saber: capacitação profissional para o mercado formal, constituição de empreendimento individual e familiar e organização de empreendimentos coletivos solidários. Para efeito de análise a pesquisa foi delimitada neste último eixo, dado seu diferencial em promover a inclusão produtiva por meio do trabalho cooperado e autogestionário. Assim, elegeu-se a abordagem qualitativa para efetivação desta dissertação combinando pesquisa documental nos projetos e relatórios referentes ao Programa Bolsa Trabalho com a realização de entrevista a coordenadores e técnicos que participaram do mesmo. Além de pesquisa bibliográfica em livros, dissertações, monografias e outras produções sobre as políticas discutidas nesse trabalho. Posto o objetivo desta dissertação consistir na análise do Programa Bolsa Trabalho, em sua articulação entre as políticas de transferência de renda, economia solidária e geração de trabalho, os resultados da pesquisa permitem concluir que a proposta de incluir social e economicamente jovens trabalhadores a partir desta estratégia se mostra possível, contudo demanda interação com as demais políticas sociais e econômicas do governo. Em relação à economia solidária, por se tratar de uma novidade política e na forma de organizar o trabalho observa-se que faltou, principalmente, esclarecimento sobre a proposta, demanda pelo grupo beneficiário e política de financiamento para implantação dos empreendimentos formados pelo Programa.

U-Pb SHRIMP and 40Ar/39Ar constraints on the timing of mineralization in the Paleoproterozoic Caxias orogenic gold deposit, São Luís cratonic fragment, Brazil

Caxias é um depósito de ouro orogênico do fragmento cratônico São Luís, que é correlacionável aos terrenos Riacianos do Cráton Oeste-Africano. O depósito se formou após o metamorfismo regional (estimado em 2100 ± 15 Ma) e está hospedado em zona de cisalhamento que secciona xistos do Grupo Aurizona (2240 ± 5 Ma) e o Microtonalito Caxias. O microtonalito foi aqui datado em 2009 ± 11 Ma, e representa um estágio magmático tardio na evolução do fragmento cratônico São Luís. Cristais de zircão com idades de 2139 ± 10 Ma foram herdados da fonte magmática ou s��o produto de contaminação durante a intrusão. A composição dos isótopos de chumbo sugere que granitoides de arco de ilhas de ca. 2160 Ma são a fonte provável para o Pb incorporado na pirita relacionada com o minério. Sericita hidrotermal mostra idade ⁴⁰Ar/³⁹Ar de 1990 ± 30 Ma, que, combinada com a idade de posicionamento do microtonalito hospedeiro, limita o evento mineralizador ao intervalo 2020-1960 Ma.

Influential Social Workers: A Preliminary Exploration of Social Work Faculty

The profession of social work in the U.S. has been influenced and is being influenced by a wide-range of advocates, politicians, practitioners, and educators. This paper is a preliminary attempt to systematically examine who social work faculty consider influential in shaping the field. Identifying influential social workers is an important step in understanding the history of a profession, its current state, and its future trajectory.

U.S. school based sealant programs: Review of their most common characteristics

In the United States, dental caries is the most common chronic illness in children, occurring five to eight times as frequently as asthma. 11 Dental caries is an unmet health need, disproportionately affecting minority groups and individuals with low socio-economic status.15,34,36 School-Based Sealant Programs were developed to target children at risk, to provide dental services in a closer geographic area, to offer low cost preventive dental services, and to educate families about oral health and prevention.1 There is scientific, evidence based literature that shows the effectiveness of dental sealants preventing dental decay. 13^ Currently, there is no central source for cataloging School-Based Sealant Programs (SBSPs). Information is scattered around publications and documents. For instance, the National Health and Nutrition Examination Survey (NHANES) does not have information about all the existing SBSPs. ^ This literature review determined which are the most common characteristics of SBSPs in the U.S. and determined the extent to which these programs provide sealants to children of low socio-economic status. The method utilized was an electronic database search. Pubmed and EBESCO host databases were searched with Mesh terms like “dental school sealant programs”, “community dentistry”, “school based sealant programs” and “oral preventive programs”. Results were organized in terms of location, population served, providers, funding source and data shared. ^ The searches produced 77 studies, from which 40 were included in this work. Only 18 U.S. states were represented in the results; however these findings are very consistent with the Best Practice Approach – School Based Sealant Programs3. Most of the SBSPs provide their services to children from low income families, and utilized the lower labor cost providers permitted by their state regulations. The author intends that this thesis work will become an aide in the development of future programs, and as evidence for the sustainability of these programs.^

Vanadium-Doped In and Sn Sulphides: Photocatalysts able to use the whole visible light spectrum

Using photocatalysis for energy applications depends, more than for environmental purposes or selective chemical synthesis, on converting as much of the solar spectrum as possible; the best photocatalyst, titania, is far from this. Many efforts are pursued to use better that spectrum in photocatalysis, by doping titania or using other materials (mainly oxides, nitrides and sulphides) to obtain a lower bandgap, even if this means decreasing the chemical potential of the electron-hole pairs. Here we introduce an alternative scheme, using an idea recently proposed for photovoltaics: the intermediate band (IB) materials. It consists in introducing in the gap of a semiconductor an intermediate level which, acting like a stepstone, allows an electron jumping from the valence band to the conduction band in two steps, each one absorbing one sub-bandgap photon. For this the IB must be partially filled, to allow both sub-bandgap transitions to proceed at comparable rates; must be made of delocalized states to minimize nonradiative recombination; and should not communicate electronically with the outer world. For photovoltaic use the optimum efficiency so achievable, over 1.5 times that given by a normal semiconductor, is obtained with an overall bandgap around 2.0 eV (which would be near-optimal also for water phtosplitting). Note that this scheme differs from the doping principle usually considered in photocatalysis, which just tries to decrease the bandgap; its aim is to keep the full bandgap chemical potential but using also lower energy photons. In the past we have proposed several IB materials based on extensively doping known semiconductors with light transition metals, checking first of all with quantum calculations that the desired IB structure results. Subsequently we have synthesized in powder form two of them: the thiospinel In2S3 and the layered compound SnS2 (having bandgaps of 2.0 and 2.2 eV respectively) where the octahedral cation is substituted at a â?10% level with vanadium, and we have verified that this substitution introduces in the absorption spectrum the sub-bandgap features predicted by the calculations. With these materials we have verified, using a simple reaction (formic acid oxidation), that the photocatalytic spectral response is indeed extended to longer wavelengths, being able to use even 700 nm photons, without largely degrading the response for above-bandgap photons (i.e. strong recombination is not induced) [3b, 4]. These materials are thus promising for efficient photoevolution of hydrogen from water; work on this is being pursued, the results of which will be presented.
