Recycling workflows and services through discovery and reuse

Scientific workflows are becoming a valuable tool for scientists to capture and automate e-Science procedures. Their success brings the opportunity to publish, share, reuse and repurpose this explicitly captured knowledge. Within the myGrid project, we have identified key resources that can be shared including complete workflows, fragments of workflows and constituent services. We have examined the alternative ways these can be described by their authors (and subsequent users), and developed a unified descriptive model to support their later discovery. By basing this model on existing standards, we have been able to extend existing Web Service and Semantic Web Service infrastructure whilst still supporting the specific needs of the e-Scientist. myGrid components enable a workflow life-cycle that extends beyond execution, to include discovery of previous relevant designs, reuse of those designs, and subsequent publication. Experience with example groups of scientists indicates that this cycle is valuable. The growing number of workflows and services mean more work is needed to support the user in effective ranking of search results, and to support the repurposing process.

Políticas públicas de segurança do Brasil e da Argentina: uma abordagem sobre os acordos de integração policial entre as unidades federativas do Codesul e da Crecenea-Litoral

Essa dissertação objetiva identificar até que ponto o acordo firmado entre o Codesul e a Crecenea-Litoral para integração do Sistema de Segurança Pública foi executado. A obra apresenta teorias sobre a origem do Estado e da Sociedade e procura relacionar esse assunto, em linhas gerais, com as problemáticas da Segurança Pública. Aborda questões relacionadas aos direitos e garantias individuais dos cidadãos. Mostra a estrutura da organização da Segurança Pública no Brasil e na Argentina e também faz considerações sobre a integração policial entre o Codesul e a Crecenea-Litoral. A metodologia utilizada privilegiou a pesquisa de campo. O estudo concluiu que a integração do Sistema de Segurança Pública entre o Codesul e a Crecenea-Litoral se encontra em uma fase embrionária. A vivência social, a praxe operacional e administrativa nos trabalhos policiais, das duas regiões, revelam que as políticas públicas no setor de segurança pública e principalmente no que se refere a integração policial são insignificantes.

A Racionalidade Sustantiva na Avaliação de Projetos em ONGSs : Três Casos

Este trabalho analisa a prática de avaliação de projetos por parte de três organizações não-govemamentais brasileiras, a partir dos conceitos da racionalidade substantiva esboçados por Guerreiro Ramos e implementados por Maurício Serva. São abordadas as condições históricas de surgimento das ONGs no Brasil, em que a formação de seus integrantes, os objetivos que perseguem e o foco de sua ação conformam o pano de fundo a partir do qual se materializa sua gestão. A avaliação é entendida aqui como um aspecto que sintetiza, de forma dinâmica, o conjunto de valores, identidades, posturas e propostas destas organizações ao processo social mais amplo com que se relacionam. Desta forma, a avaliação de projetos ilustra uma maneira de administrar peculiar a organizações de natureza não-govemamental. O trabalho analisa, ainda, os limites da racionalidade substantiva nos processos de avaliação estudados e aponta o conhecimento sobre o universo das organizações não-govemamentais como gerador de possíveis aprendizagens para uma administração pública que pretenda aprimorar a prática democrática.

Não há que ser flexível, há que ser forte: um estudo sobre os limites no trabalho e na família

É cada vez maior o número de indivíduos que lidam com responsabilidades familiares e de trabalho nas suas rotinas do dia a dia. Esse cenário tem levado a um maior número de investigações sobre as relações entre trabalho e família e os impactos das mesmas na vida dos indivíduos e nas organizações. Diversas são as abordagens e perspectivas teóricas que buscam explicar a ligação entre esses dois domínios e que exploram os efeitos que trabalho e família podem exercer um sobre o outro. O presente estudo aborda a relação trabalho-família a partir da concepção dos limites existentes nestes domínios, limites estes que influenciam diretamente no modo como a interface trabalho-família é construída. São desenvolvidas hipóteses de pesquisa que exploram o constructo força do limite (boundary strength), seus antecedentes e sua relação com o conflito trabalho-família e com o estresse ocupacional. Propõe-se ainda uma relação de moderação do suporte social na relação entre conflito trabalho-família e estresse ocupacional. Para testar a validade empírica do modelo proposto, um estudo de campo é conduzido, com 401 funcionários de diversas organizações no Brasil. Os resultados sugerem que quanto maior a força do limite na família e no trabalho, menor o conflito trabalho-família experimentado pelos indivíduos e consequentemente menor o nível de estresse ocupacional. O teste empírico deu suporte ao papel moderador do suporte social de chefes e colegas de trabalho na relação entre o conflito trabalho-família e o estresse ocupacional. Implicações teóricas e práticas dos resultados obtidos são explicitadas, além de sugestões para pesquisas futuras. Espera-se que o tema amplie o foco de análise da interface trabalho-família e auxilie na compreensão da teoria e da prática organizacional.

Formação continuada: um estudo sobre fatores motivacionais e a participação de professores em cursos de especialização

O estudo aqui apresentado tem como objetivo analisar e compreender fatores motivacionais que impulsionam profissionais de educação do ensino básico a buscarem participação em cursos de especialização lato sensu na área de educação. O caminho metodológico escolhido e que embasou a análise e a interpretação dos dados foi a Técnica de Análise de Conteúdo, tendo como suporte os estudos de Bardin (2011). O presente estudo inclui-se no modelo de pesquisa de abordagem quantitativa e qualitativa. O questionário é composto por questões relacionadas com o levantamento dos dados biográficos dos respondentes, os itens estão configurados em uma escala de Likert sobre os fatores motivacionais que mobilizam os profissionais de educação a participarem do curso de especialização e duas questões subjetivas sobre as expectativas dos respondentes acerca das novas competências adquiridas e contribuições para a prática profissional. O estudo foi realizado através da pesquisa de campo onde coletamos dados a partir de um questionário semiestruturado. A amostra estudada está composta por 122 (cento e vinte e dois) respondentes qualificados para o nosso estudo, com formação em pedagogia ou licenciaturas diversas. O campo de estudo foi a FAFIRE – Faculdade Frassinete do Recife - no ano de 2012 e considerou alunos participantes de nove cursos de especialização voltados para a área de educação. Os resultados nos permitiram identificar e compreender os principais fatores que motivam os professores na busca de ampliação do seu conhecimento, podendo ser sintetizados como sendo fatores voltados para a profissionalidade e prática docente, empregabilidade e a questão salarial.

Valuing emerging markets companies : new approaches to determine the effective exposure to country risk

The aim of this paper is to propose new methods to measure the effective exposure to country risk of emerging-market companies. Starting from Damodaran (2003), we propose seven new approaches and a revised CAPM for emerging markets companies. The “Prospective Lambda” represents the effective exposure according to analysts’ estimates of growth. The “Relative Lambda” relies on the firm value estimated through a relative valuation. The “Retrospective Lambda” represents the ex-post effective exposure to country risk. The “Company Effective Risk Premium” is a generalization of the Retrospective Lambda, and expresses the premium effectively requested by investors to invest in that specific company in the past year. “The Actual Lambda” and the “Company Actual Risk Premium” represent, respectively, the actual exposure to country risk of a company and the actual premium requested by investors to invest in that specific company. The “Industry Lambda” reflects the median exposure to country risk of the industry in which the company belongs. We tested our new measures of exposure to country risk on the Latin American emerging markets companies according to the classification of the MSCI Emerging Markets Latin America Index. The results confirm that the new approaches can be effectively applied by financial analysts to stable-growth companies that operate in emerging markets and to mature markets companies that operate in emerging markets, providing with a more reliable estimate of both the premium effectively requested by investors in the past and the actual premium. Applying the new approaches, the cost of equity reflects the effective exposure of a company to country risk without being over- or underestimated, as is the case with other existing approaches.

O projeto politico pedagógico de enfermagem e o sistema único de saúde: a visão de discentes

This research aims to analyze, in the view of students, the pedagogic project of undergraduate nursing course, of UFRN, and its articulation with the SUS, in an attempt to understand the issues that permeate the teaching and learning of nursing. This is a qualitative study that used the focus group technique as a tool to collect empirical data. There were three meetings, where we had the collaboration of 23 graduating students from the eighth period of the semester 2009.1. For the analysis of information, we use a theoretical framework based on curriculum guidelines and basic principles of the SUS, making the analogy of the results with the metaphor of Greek mythology, Ariadne's thread, in dialogue with authors who discuss education as a transformative practice. Thus, the texture of the yarn was built of five thematic fields: joint the pedagogic project with the SUS; the teaching/service and theory/practice relation; interdisciplinarity or transdisciplinarity; didactic/methodological and relational approaches; and co-participation of students in the pedagogic project. According to the discussions, we find many difficulties in the teaching and learning process of undergraduate nursing in UFRN to strengthen the SUS, including: dislocation of educational institutions with services, professionals, managers and community; dichotomy between theory and practice; reality of services as a learning field and working process in health; posture adopted by professionals, teachers and other subjects included in the process of health education; decontextualization and fragmentation of teaching with the practice in health and nursing; excessive use of very illustrative methodologies, but little problem-solving; difficult and precarious situation in the relations between teachers and between teachers/students, regarding the acceptance of differences; absence of participation of students in the evaluation process and conduct of the educational project in progress. In this sense, we understand the need an auto-reflexive act of teaching and conducting collective pedagogical course with a view to achieving the SUS. Thus, it is necessary to support practices motivated by the polyphonic dialogue and the exercise of symbiosis and autopoiesis of subjects/actors jointly responsible for the ongoing process of learning for life.

Abordagens pedagógicas na formação de enfermeiros : compreensão de docentes de enfermagem

In the new world order is notorious changes in social, ethical, economical and political aspects in the society, which reach incisively higher education, requiring a number of modifications and a new vision in nursing education, in order to meet the demands of the Unique Health System. Thus, the Higher Education Institutes (HEI) and teachers are invited to face new challenges and reflect on their practices, using pedagogical approaches and innovative methodologies to meet the requirements of a globalized society. This study has as an objective to analyze the perspective of teachers in what concern the pedagogical approaches used in nursing education and to identify pedagogical approaches utilized by teachers in nursing education. This is a field research of exploratory kind, descriptive, of quantitative approach. The search was conducted at the Department of Nursing of the Federal University of Rio Grande do Norte UFRN, based in the city of Natal. The population consisted of forty-six teachers. From this population was selected a sample of twenty teachers. Data collection occurred from August to September 2011, through the utilization of the technique of interview and questionnaire. The obtained data were analyzed in two moments. In the first moment, was carried out the quantitative analysis that refers to the obtained data through the interview technique, methodological procedures were submitted to the content analysis proposed by Bardin. On the second moment, concerning the quantitative analysis of the questionnaires applied to the teachers and of the identification data, which were digitized and transferred to a spreadsheet electronic of Microsoft Excel XP, tabulated and organized into tables, containing their relative and absolute frequencies. It is worth mentioning that were respected the aspects of the CNS Resolution 196/96. With regard to the characteristics of research participants, 20% were male; with a degree of titration of 55% doctorates; regarding time of service there was a greater representation from 15 to 45 years, with 45%. The results showed that 90% of teachers who participated in the research have an appropriate understanding of non-critical pedagogical approaches, only 10% had an inadequate understanding. However, 70% of teachers, despite having an adequate understanding, reported difficulties when attempting to implement these pedagogies. Most teachers, with representability of 80% consider the non-critical pedagogies relevant in nursing education, as well as critical pedagogies, being represented by 95% of teachers. It was concluded that both critical and non-critical pedagogies are in teachers practice of undergraduate nursing education. It feels like a moment of transition, since the presence of new ways of teaching as a part of this educational context, with educational models that give value to scientific, ethical and personal aspects in the educational process. The research contains limitations, however highlights the contribution of new possibilities for action, reflection on the context of performance, maximizing the pedagogical skills necessary to conduct teaching process, in line with the new educational paradigm of higher education

O gênero joke em atividades de inglês: uma proposta intercultural de ensino-aprendizagem para o ensino médio

Our research has arisen from the interest of aligning English as a Foreign Language (EFL) classroom practice to current discussions in the ambit of learning and teaching Foreign Languages (FLs). Because of the need to integrate the linguistic development to the development of notions clung to the practice of citizenship, we have adopted a cultural perspective. We have noticed jokes as a fertile ground for discussing cultural aspects in classroom. Considering such factors, our research question is: how to explore cultural aspects in jokes for the elaboration of EFL activities which aim for the development of intercultural competence and interaction? Therefore, our general goal is to explore cultural aspects in jokes for the elaboration of EFL teaching and learning activities and our specific goals are: (I) to study official suggestions (LDB, 1996; PCNEM, 2000; PCN+EM, 2002; OCEM, 2006) regarding culture at foreign languages teaching and learning, (II) to select 05 (five) jokes and analyze them focusing on their cultural aspects, (III) to identify possible interpretations for jokes; (IV) to elaborate EFL activities which grant a privilege to jokes cultural aspects. This investigation is descriptive and documental and relies on qualitative paradigm (CHIZZOTTI, 2010; FLICK, 2009; CHAROUX, 2006; BOGDAN; BIKLEN, 1994; 1992). The corpus is constituted by jokes taken from Internet sites and by official documents (LDB, 1996; PCNEM, 1998; PCN+EM, 2000; OCEM, 2006). For the elaboration of activities we have chosen a weaker version of Content-based instruction (CBI), in which contents are cultural aspects in jokes and we have undertaken a reflection on methods, approaches and perspectives, among which there are notions about post-method and CBI, which talk to EFL learning and teaching. For theoretical support we have some discussions about FL methods and approaches (BELL, 2003; KUMARAVADIVELU, 2003; WESCHE; SKEHAN, 2002; PRABHU, 1990), a cultural perspective (KRAMSCH, 1998, 1996, 1993; BYRAM; FENG, 2004), some works in Linguistics about jokes (POSSENTI, 2010, 1998; CHIARO, 1992); notions about implicit (MAINGUENEAU, 2004, 1996; CHARAUDEAU; MAINGUENEAU, 2012) and about ambiguity (KEMPSON, 1977; CHARAUDEAU; MAINGUENEAU, 2012; TRASK, 2011), having the adoption of such categories emerged from the analyzes of some jokes

Registros de ordens e ocorrências: uma prática de letramento no trabalho da enfermagem hospitalar

Nursing documentation is a literacy practice which is regulated by law. Among the written practices of the literacy field, nursing registration is understood as the attendance resume of the main problems and occurrences on duty. In other words it is a document and a communication instrument used by hospital orderly on duty. It s main goal is to keep a record of the information which is necessary to the continuity of the activities as well as to the assistance to the patients. Taking into consideration the complexity of this kind of literacy practice, this study which took place in a hospital context, aims at studying the nursing registration process in order to explain its implementation in the nursing field. The discussion is situated in the area of applied linguistics, and it makes a linkage between linguistics approaches and language questions which are related to the area of discourse at work. The theoretical foundations come from contemporary literacy studies such as Hamilton (2000) who proposes the following categories: participants, domain, artifacts and activities. The analysis was guided by the principles of the ethnographic methodology which proposes that the researcher spends much time in the field and uses a set of techniques in order to collect data related to the subjects speech as well as their deeds concerning the research main object. The data were collected through field observations, analysis of 100 nursing records, 04 reflective sessions and interviews as well involving 36 nurses. On one hand, the analysis reveals the importance of the nursing records in terms of documentation and communication. On the other hand, it shows informational, compositional as well as normative difficulties in terms of linguistics and legal aspects. For, we conclude that these questions need to be addressed through the process of intervention especially in events of teacher in service activities so that the professional nurses may improve their practice in relation to the elaboration of the nursing documentation on duty

Muscle lesion treatment in Brazilian soccer players: Theory vs. Practice

Background: In this study we evaluated the rehabilitation profile of Brazilian soccer players which underwent lower limb muscle lesions.Methods: This is a descriptive investigation. We evaluated 139 professional soccer players (1724 years old). We evaluated the following variables: muscle lesion diagnosis, symptoms, non steroidal anti-inflammatory used, physiotherapy treatment, which physiotherapy recourses was used if treated and train adaptation.Results: In great part of the athletes muscle lesion remained between 2 weeks and 1 month. Around 54% were diagnosed by a physician; the other part was diagnosed by a physical therapist. Non steroidal anti-inflammatory were prescribed by physicians in 42% of the cases; in 7% the physical therapist prescribed the medication while in 49% of the cases the masseur prescribed the drug. More than 1/4 of the athletes received physiotherapy treatement between 48 hours and 5 days. Isometric exercise therapy was applied in 15% of the cases. 63% were not accompanied by the physiotherapist on their return to the field. 48% received massages immediately after injury.Conclusion: We presented discrepancy between the recommended theory described by several researches and the practice. We indicate the necessity of recycling in a general context the rehabilitation of muscle injuries.

Organochlorine pesticides and polychlorinated biphenyls in soil and water samples in the northeastern part of São Paulo State, Brazil

Detailed analyses of persistent organic pollutants (POPs) such as organochlorine pesticides (OCPs), hexachlorocyclohexane (HCH) isomers (HCHs), dichlorodiphenyltrichloro ethane (DDT) and its metabolites (DDTs) and congeners of polychlorinated biphenyls (PCBs) in soil and surface water from the northeastern São Paulo, Brazil allowed the evaluation of the contamination status, distribution and possible pollution sources. The pesticides and PCBs demonstrated markedly different distributions, reflecting different agricultural, domestic and industrial usage in each region studied. The ranges of HCH, DDT, and PCBs concentrations in the soil samples were 0.05-0.92, 0.12-11.01, 0.02-0.25 ng g(-1) dry wt, respectively, and in the surface water samples were 0.02-0.6, 0.02-0.58 and 0.02-0.5 ng l(-1), respectively. Overall elevated levels of DDT and PCB were recorded in region 2, a site very close to melting, automotive batteries industries, and agricultural practice regions. High ratios of metabolites of DDT to DDT isomers revealed the recent use of DDT in this environment. The sources of contamination are closely related to human activities, such as domestic and industrial discharge, street runoff, agricultural pesticides and soil erosion, due to deforestation as well as atmospheric transport.

Arranjos urbanos e subjetivos contemporâneos na invenção de territórios turísticos

We seek consistency empirical and analytical rigor to the concept of touristification in the course of the contemporary arrangements of subjectivity and urbanity stations through a landscape of social (dis)encounters between residents and foreigners living in the capital of Rio Grande do Norte, Natal. In the last three decades the city has become a major destination country for national and international tourism, making tourism an important monitor of choreography in search of synchrony between cities and subjectivities, orchestrated by the cyclical crises and the relentless battle for systemic capitalistic expansion and survival. We proceed with an ethnographic and cartographic inspiration in Ponta Negra, where the waterfront redevelopment in 2000 conducted by the government, influenced the implementation of various establishments, services and practices related to the construction of Natal s major industry hub of tourism and entertainment. We proposed an arch-genealogy of touristification inspared on Michel Foucault analytical perspective, increased by authors in confluence or in different theoretical and methodological approaches, among which stand out Karl Marx, Gilles Deleuze and Felix Guattari, Michael Hardt and Antonio Negri. The reflections that initially turned to the advancement of the sphere of consumerism as the issue capable of articulating the developmental trajectory of the capitalist system and the practice of tourism, promoting some effects (un)desirable in the conflictual dynamics of the condition of the district of Ponta Negra, territory each again (re) produces the designs to meet the consumption by affluent portion of the population and foreign, encountering social exclusion and inclusion differentiated a growing trend. We go forward with an analysis of the "liberation of desire" phenomenal features of the process of producing subjective, providing a breakdown of the recent world s financial crisis initially, but proved social and political crisis also, through a plot derived from the operation of real estate speculation, which Natal is mainly caught through touristification, showing the outlines of a generalized crisis in establishing a new order buoyed by the emergence of a context "biopolitical" since it is a major route that uses the capital to survive and expand, while guiding the process of "strategic beautification" held in Ponta Negra, problematized by us. We conclude by assessing the appropriateness of proposing on further analysis to explore the establishment of a "new social ontology in terms of interference touristification ongoing and the constitution of a "new order" local/global, away from that characterize a system's capitalist overcoming, try to give emphasis in the current stage of the radicalization of a capitalistic utopia

Morphometric study of placental villi and vessels in women with mild hyperglycemia or gestational or overt diabetes

In this study, morphometric measures of placental terminal villi and villous vessels were compared in overt, as well as gestational diabetes mellitus, and mild hyperglycemia diagnosed by oral 100 g glucose tolerance test (100 g-OGTT) and glucose profile (GP). At delivery (gestational age >= 34 weeks) a total of 207 placentas were assigned to a control group (n = 56) or to one of three groups complicated by mild hyperglycemia (n = 5 1), gestational diabetes (n = 59) and overt diabetes (n = 4 1). Placenta samples were randomly selected for blind morphometric assessment with an image analyser. Morphometric measures obtained included area and number of terminal villi and their respective villous vessels. Statistical analyses were performed using the chi-square test, ANOVA and stepwise regression (p <= 0.05). Glycemic means were 86.2 mg/dL in controls, 98.9 mg/dL in mild hyperglycemia, 114.1 mg/dL in gestational diabetes and 122.1 mg/dL in overt diabetes. Our results show that abnormal maternal glycemic levels may change the placental morphometric characteristics related to materno-fetal exchanges. (C) 2007 Elsevier B.V.. All rights reserved.
