Authors: Melo Flávia Adrilene De Araújo , Barilli Elomar Christina Vieira Castilho
Published: February 2017

O presente artigo discute o papel da informação e do conhecimento no âmbito organizacional, procurando enfatizar, além de sua importância, o novo foco de sua conceituação, entendimento e aplicação dentro do cenário da chamada “era do conhecimento e da aprendizagem contínua”, entendendo-a como fruto de um contexto que impõe constantes mudanças inerentes a um mundo em transformação. Este cenário parece desafiar a inteligência humana a pensar novos modelos de gestão que contemplem crescimento pessoal e organizacional, como meio de agregar valor aos seus processos, bens e serviços, única forma de sobreviver às demandas da nova sociedade. Embora sejam inúmeros os enfoques e objetivos, o que a bibliografia atual aponta como consenso é o fato de a vantagem competitiva das empresas estar diretamente ligada a ativos intangíveis, conhecimento e aprendizagem. Não basta mais prospectar informação, armazená- la, tratá-la, analisá-la, gerar decisão e implementar ações. É preciso que a empresa aprenda com as experiências vivenciadas, estruturando seu próprio processo histórico, contínuo e inacabado. Dessa forma, a conclusão do presente artigo aponta para a integração informação/ conhecimento, entendendo-se a primeira como fruto da busca e análise com vistas à sua coerente utilização; já o segundo como o resultado da aplicação contextual de forma a gerar experiência individual e coletiva, elementos precursores da chamada aprendizagem organizacional. Espera-se que este escrito, portanto, motive o leitor a repensar novos paradigmas de competitividade, estratégias organizacionais e estruturas institucionais, onde a integração entre informação e conhecimento seja considerada chave para o sucesso das empresas nesta nova ordem mundial.
Diferenciação de cervejas usando fosforimetria
Authors: Cardoso Carlos Eduardo
Published: February 2017

Cerveja é uma mistura complexa que consiste principalmente de água e etanol, com 0,5% de sólidos dissolvidos. A caracterização de amostras complexas nestes casos, normalmente emprega técnicas analíticas baseadas na separação destes componentes. Alternativamente, o uso de métodos espectroscópicos vem sendo reconhecido como método rápido e sensível, com aplicabilidade para uma grande variedade de produtos. Assim, o presente trabalho teve por objetivo aplicar a fosforimetria em substrato sólido na temperatura ambiente para a caracterização de amostras de dois tipos de cervejas produzidas no mercado nacional através do efeito externo do átomo pesado e do efeito de um modificador de superfície na indução da fosforescência. Como resultado, uma metodologia para caracterização de amostras de cervejas foi desenvolvida. Parâmetros experimentais e instrumentais foram otimizados com o intuito de minimizar a interferência entre os processos radiativos. Isso foi conseguido pela combinação do uso de surfactante SDS 0,07 mol L-1 e de átomo pesado, KI 1,0 mol L-1 e também pela utilização de tempos adequados de abertura do detector e tempo de retardo.

Authors: Souza Ana Carla da S. , Cardoso Carlos Eduardo , Neto Miguel Rascado Fraguas
Published: February 2017

O uso excessivo de fósforo na forma de tripolifosfato de sódio (STPP) em detergentes em pó tem e contribuído de maneira significativa no processo de eutrofização da águas e consequentemente na poluição dos corpos hídricos. Visando a redução e eventual eliminação do uso de fosfato nos detergentes, o Conselho Nacional do Meio Ambiente criou a resolução CONAMA 359/05, que dispõe sobre a regulamentação do teor de fósforo em detergentes em pó para o uso no mercado nacional. O presente trabalho tem como objetivo determinar e comparar a concentração de fosfato em detergentes em pó, fabricados em três países (Omã, França e Brasil), de acordo com esta resolução. Para determinar a concentração do fosfato utilizou-se a técnica de titulação por volumetria.

Published: February 2017

Os resíduos gerados pelas atividades humanas representam um dos maiores problemas da atualidade, uma vez que tratados de maneira negligente e inadequada constituem graves riscos ao meio ambiente, à saúde humana e de animais. Integrado a este universo, temos a questão dos resíduos de serviços de saúde (RSS), que por suas particularidades torna-se inexeqüível o seu lançamento em rede pública de esgotos ou em corpos d’água, exigindo-se para isso, soluções técnicas e economicamente viáveis em face à melhor tecnologia disponível (ANVISA 2005). A consciência ambiental da população e a legislação tem levado as instituições hospitalares, de ensino e pesquisa a implantarem a gestão de resíduos laboratoriais buscando, desta forma, minimizar os riscos e impactos causados por tais resíduos. O presente trabalho tem por objetivo identificar e descrever a quantidade diária dos resíduos gerados nos laboratórios da área de saúde do Campus da Universidade Severino Sombra, justificando-se pela imprescindível necessidade de adequação às normas estabelecidas por lei e aos protocolos da instituição reconhecendo que muito já foi feito, todavia, ainda há muito o que aprimorar.

Published: February 2017

Inúmeras indústrias de cosméticos têm direcionado suas pesquisas no desenvolvimento de novos produtos utilizando matérias-primas de origens vegetais, representando uma alternativa de substituição dos materiais sintéticos por naturais. Uma tendência evidenciada ultimamente é a utilização de resíduos do processamento de alimentos tais como sementes e cascas, devido o grande potencial dos componentes bioativos dos mesmos. O uso do caroço de azeitona na área cosmética apresenta características favoráveis devido à qualidade dos mesmos ajudar na esfoliação da pele. O caroço da azeitona constitui um dos principais resíduos gerados nas indústrias de processamento de azeite. Atualmente estes resíduos são geralmente queimados, a fim de recuperar o calor residual da sua combustão. Devido as suas substâncias químicas e físicas, o caroço é rico em componentes bioativos para sua utilização ser restringida apenas a processos de combustão. Diante do exposto o objetivo deste trabalho foi produzir um sabonete esfoliante em barra à base de caroço de azeitona, agregando valor a este resíduo.

Para isso, foi aplicado um modelo de crescimento definido por um sistema de equações diferenciais, devido a Lotka-Volterra, que envolve a iteração entre duas espécies, neste caso a população da cidade e apopulação de estudantes, sabendo que o número de moradias desocupadas é dependente da procura pelos estudantes para aluguéis e estas moradias ocupadas influenciam também a oferta e a construção de novos empreendimentos na cidade.
Applying Computerized Adaptive Testing to the Four-Dimensional Symptom Questionnaire (4DSQ): A Simulation Study
Authors: Magnée Tessa , de Beurs Derek P , Terluin Berend , Verhaak Peter F
Published: February 2017

Background

Efficient screening questionnaires are useful in general practice. Computerized adaptive testing (CAT) is a method to improve the efficiency of questionnaires, as only the items that are particularly informative for a certain responder are dynamically selected.

Objective

The objective of this study was to test whether CAT could improve the efficiency of the Four-Dimensional Symptom Questionnaire (4DSQ), a frequently used self-report questionnaire designed to assess common psychosocial problems in general practice.

Methods

A simulation study was conducted using a sample of Dutch patients visiting a general practitioner (GP) with psychological problems (n=379). Responders completed a paper-and-pencil version of the 50-item 4DSQ and a psychometric evaluation was performed to check if the data agreed with item response theory (IRT) assumptions. Next, a CAT simulation was performed for each of the four 4DSQ scales (distress, depression, anxiety, and somatization), based on the given responses as if they had been collected through CAT. The following two stopping rules were applied for the administration of items: (1) stop if measurement precision is below a predefined level, or (2) stop if more than half of the items of the subscale are administered.

Results

In general, the items of each of the four scales agreed with IRT assumptions. Application of the first stopping rule reduced the length of the questionnaire by 38% (from 50 to 31 items on average). When the second stopping rule was also applied, the total number of items could be reduced by 56% (from 50 to 22 items on average).

Conclusions

CAT seems useful for improving the efficiency of the 4DSQ by 56% without losing a considerable amount of measurement precision. The CAT version of the 4DSQ may be useful as part of an online assessment to investigate the severity of mental health problems of patients visiting a GP. This simulation study is the first step needed for the development a CAT version of the 4DSQ. A CAT version of the 4DSQ could be of high value for Dutch GPs since increasing numbers of patients with mental health problems are visiting the general practice. In further research, the results of a real-time CAT should be compared with the results of the administration of the full scale.
Italian academic pedagogical magazines in the history of education in the XX century
Authors: Polenghi Simonetta
Published: February 2017

Keywords: Italian academic pedagogical magazines, extensive historical works, educational publishing housesThis paper aims to reconstruct the main strands of Italian educational thought using academic pedagogical magazines as a mirror for scientific and political developments through the years. I shall follow a chronological order, indicating the main changes which have occurred in Italy since its unification, concentrating on cultural turns and academic shifts. Pedagogical and school magazines have been the object of quite a number of extensive historical works, followed by other studies on school and educational publishing houses. Giorgio Chiosso has been the leading figure in this research for many years, having directed national projects in pedagogical journals and publishing houses, which have provided important historical tools, such as the catalogues of Italian school and educational magazines 1820-1945 (Chiosso, 1989, 1992, 1993, 1997) and the catalogues of Italian pedagogical publishing houses in the XIX and XX centuries (Chiosso, 2003a, 2008). Whilst the pedagogical magazines before and after unification have been carefully catalogued, the educational journals of Republican Italy have yet to be researched. An updated short biography and bibliography of the quoted educationalists can be found in the recent biographical dictionary directed by Chiosso and Sani (2013).
Erziehungswissenschaft in Deutschland – nationale Form, kulturelle Differenzen
Authors: Tenorth Heinz-Elmar
Published: February 2017

Schlüsselwörter: Disziplingeschichte, deutsche Erziehungswissenschaft, Bedeutung der KonfessionDisziplingeschichte wird bisher vorrangig auf nationale Kontexte bezogen und wenn kulturell, dann in Sprachkulturen und Theorietraditionen diskutiert und für das Hochschulsystem erforscht, wie sie für den deutschsprachigen Bereich typisch sind. Die Geschichte der Erziehungswissenschaft in Deutschland zeigt demgegenüber, dass jenseits nationaler Einheitsformen, wie sie durch die Sprache, die Struktur der Universitäten und durch die Ordnung der Lehrerbildung erzwungen werden, weitere kulturelle und soziale Differenzen bedeutsam bleiben. Der Vortrag soll vor allem die fortdauernde Bedeutung der Konfession und die politische und gewerkschaftliche Organisation von Lehrern und Parteien als Differenzmerkmal herausarbeiten und die Mechanismen klären, wie diese Faktoren wirksam werden.Keywords: history of discipline, German science of education, role of religionNations and their cultural context, mostly defined by language, by the specific national systems of higher education and by the forms of teacher training dominate worldwide the current analysis of the discipline of education in its modern history, despite of all international relationships. The central thesis of the here presented arguments is that in the case of German Pedagogy and the German science of education the concentration on nation, language and the system of higher education is misleading in understanding the genuine dynamic of their special history in Germany. Contrary to the dominating interpretation the article tries to demonstrate that hereby the central role of religion, of socio-political factors like the tradition and form of the trade unions of teachers and of the pedagogical and political ideologies of the political parties is ignored or underestimated in its continuing impact on the discipline of education. The role of these factors is both effective and significant in the structure of arguments and theory-building and in the construction of social networks inside and outside of the academic field

Blanqueo de activos: la experiencia costarricense
Authors: Azofeifa-Céspedes Arturo
Published: February 2017

El propósito de este trabajo es demostrar que la legitimación de activos representa un problema que debilita gobiernos, afecta economías, deteriora a la sociedad, genera corrupción y aumentos significativos en la violencia, por ende contribuye a la inseguridad ciudadana, aun cuando las autoridades policiales hagan sus mayores esfuerzos para combatir este flagelo. Cualquier ciudadano debe ser capaz de entender que eventualmente puede sufrir las consecuencias del problema y debe ser consciente de que debe aportar su granito de arena para luchar contra este flagelo. La lucha internacional contra la legitimación de activos demuestra que únicamente se puede ganar si cada ser humano, mediante la concienciación, reconoce en sus valores y en su aporte individual, las armas más poderosas para combatir este mal.
Optimization of vanadium oxide catalyst for the oxidation of 3-methylpyridine into nicotinic acid

Published: February 2017

Upon modification of V2O5 with SnO2 or ZrO2, increase in the activity and selectivity of the vanadium-oxide catalyst in the vapor-phase oxidation of 3-methylpyridine into nicotinic acid were observed. It was shown that the promoting effects of SnO2 and ZrO2 were the result of increases under their influence of the proton affinity of the vanadyl oxygen and decreases in the enthalpy of deprotonation of the methyl group of the substrate, connected by a nitrogen atom with the Lewis acidic center (vanadium ion). The given characteristics were calculated by the density functional theory quantum-chemical method. Modification of binary V2O5?SnO2 and V2O5?ZrO2?catalysts by TiO2 addition resulted in a further increase in the nucleophility of the vanadyl oxygen and, as a consequence, an increase in the catalytic activity and selectivity for nicotinic acid formation.
Investments and Risk Transfers
Authors: Baldenius Tim , Michaeli Beatrice
Published: February 2017

We demonstrate a novel link between relationship-specific investments and risk in a setting where division managers operate under moral hazard and collaborate on joint projects. Specific investments increase efficiency at the margin. This expands the scale of operations and thereby adds to the compensation risk borne by the managers. Accounting for this investment/risk link overturns key findings from prior incomplete contracting studies. We find that if the investing manager has full bargaining power vis-à-vis the other manager, he will underinvest relative to the benchmark of contractible investments; with equal bargaining power, however, he may overinvest. The reason is that the investing manager internalizes only his own share of the investment-induced risk premium (we label this a “risk transfer”), whereas the principal internalizes both managers' incremental risk premia. We show that high pay-performance sensitivity (PPS) reduces the managers' incentives to invest in relationship-specific assets. The optimal PPS, thus, trades off investment and effort incentives.

Abstract. Levenberg Marquardt (LM) algorithm algorithm is a developed backpropagation algorithm that is improved to speed up the training process with a numerical optimization technique, while the Backpropagation Gradient Descent Adaptive Gain (BPGD/AG) algorithm is developed backpropagation algorithms that is improved with a heuristic technique. The comparison of both algorithms is needed to find a better algorithm to provide accurate results on prediction cases. Comparative analysis based on the speed of convergence by considering the number of epoch is required to achieve convergence while training and it is also based on the accuracy of the testing results by calculating the MAPE and NMSE values for unemployment prediction cases in Central Java. The test results show that the LM algorithm achieves the MSE convergences with an iteration of 99 epochs, while the BPGD/AG algorithm achieves the MSE convergences with an iteration of 27506 epochs. The unemployment prediction by the LM algorithm provides an average MAPE 7.5% and the average NMSE 0.16453.

Abstract. Ant Colony Optimization (ACO) is an optimization algorithm which can be used for image edge detection. In traditional ACO, the initial ant are randomly distributed. This condition can cause an imbalance ants distribution. Based on this problem, a modified ant distribution in ACO is proposed to optimize the deployment of ant based gradient. Gradient value is used to determine the placement of the ants. Ants are not distributed randomly, but are placed in the highest gradient. This method is expected to be used to optimize the path discovery. Based on the test results, the use of the proposed ACO modification can obtain an average value of the Peak Signal to Noise Ratio (PSNR) of 12.724. Meanwhile, the use of the traditional ACO can obtain an average value of PSNR of 12.268. These results indicate that the ACO modification is capable of generating output image better than traditional ACO in which ants are initially distributed randomly.Keywords: Ant Colony Optimization, gradient, Edge Detection, Peak Signal to Noise RatioÂ Abstrak. Ant Colony Optimization (ACO) merupakan algoritma optimasi, yang dapat digunakan untuk deteksi tepi pada citra Pada ACO tradisional, semut awal disebarkan secara acak. Kondisi ini dapat menyebabkan ketidakseimbangan distribusi semut. Berdasarkan permasalahan tersebut, modifikasi distribusi semut pada ACO diusulkan untuk mengoptimalkan penempatan semut berdasarkan gradient. Nilai gradient digunakan untuk menentukan penempatan semut. Semut tidak disebar secara acak akan tetapi ditempatkan di gradient tertinggi. Cara ini diharapkan dapat digunakan untuk optimasi penemuan jalur. Berdasarkan hasil uji coba, dengan menggunakan ACO modifikasi yang diusulkan dapat diperoleh nilai rata-rata Peak Signal to Noise Ratio (PSNR) 12,724. Sedangkan, menggunakan ACO tradisional diperoleh nilai rata-rata PSNR 12,268. Hasil ini menunjukkan bahwa ACO modifikasi mampu menghasilkan citra keluaran yang lebih baik dibandingkan ACO tradisional yang sebaran semut awalnya dilakukan secara acak.Kata Kunci: Ant Colony Optimization, gradient, deteksi tepi, Peak Signal to Noise Ratio
