No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção.Na economia globalizada e altamente competitiva da atualidade, torna-se imperativa a necessidade de inovar, levando em consideração os aspectos ambientais. A implementação de um sistema de gestão ambiental de uma empresa pode ser vista como uma inovação, uma vez que trata de um processo que exige uma mudança comportamental e organizacional

Estratégia, gestão em qualidade na indústria hoteleira: estudo de caso Hotel Lancaster em Curitiba
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Produção, Florianópolis, 2000.O presente trabalho procura demonstrar a importância de a indústria hoteleira ter implantado o programa QTS - ISO 9.002, enfocando ações efetivas que levam o empreendimento ao sucesso, mantendo-o no mercado. Considerou-se que a certificação está provocando mudanças no atendimento do setor hoteleiro, exigindo-se uma avaliação com critérios mais modernos definidos agora pela EMBRATUR. Isto significa uma mudança na distribuição das estrelas onde a avaliação se dá pelo desempenho dos serviços, deixando de ser simples referências aleatórias. Ainda, o estudo procurou mostrar que a implantação de critérios de Qualidade Total nos Serviços aumenta os lucros, e apesar deste inteiro processo ser custoso, é financeiramente compensador. Também, evidenciou-se no corpo do estudo que são necessários muito estudos e avaliações futuras a fim de aprimorar os resultados e favorecer os órgãos competentes com sugestões e propostas construtivas

No full textMeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A convergent linear finite element scheme for the Maxwell-Landau-Lifshitz-Gilbert equations
No full textBanas L, Page M, Praetorius D. A convergent linear finite element scheme for the Maxwell-Landau-Lifshitz-Gilbert equations. Electronic Transactions on Numerical Analysis. 2015;44:250-270.We consider the lowest-order finite element discretization of the nonlinear system of Maxwell's and Landau-Lifshitz-Gilbert equations (MLLG). Two algorithms are proposed to numerically solve this problem, both of which only require the solution of at most two linear systems per time step. One of the algorithms is decoupled in the sense that it consists of the sequential computation of the magnetization and afterwards the magnetic and electric field. Under some mild assumptions on the effective field, we show that both algorithms converge towards weak solutions of the MLLG system. Numerical experiments for a micromagnetic benchmark problem demonstrate the performance of the proposed algorithms
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
