Usabilidade da Interface do Sistema Eletrônico de Editoração de Revistas: um estudo da revista BiblioCanto da UFRN

The electronic journals correspond publishing channels and dissemination of scientific information. Through them, users can spread their studies as well as developing new researches. One of the systems used for creation and e-journals management is the Electronic System for Journal Publishing (SEER), used in the construction of periodic portals, as well as the creation of magazines in isolation. In this purport, it is believed that the management systems and creation of e-journals should be developed (internally and externally) according to the needs of its users. In the case of internal development, some of these processes refer to the copyright registration and submission of articles, which, in turn, are relevant tasks in the editorial process. Thus, the proposed study, thematic Usability of scientific journals, aims to analyze the usability of the copyright registration process and submission of articles in the Electronic System for Journal Publishing through BiblioCanto magazine, part of the Electronic Journals Portal of the Federal University of Rio Grande do Norte (UFRN). For the realization of the research, two valuation techniques were used: the Usability Test with a total of twenty participants and the Cooperative Evaluation, with the same number of participants separated in four categories considered target audience of that magazine, namely: undergraduate students, graduate students, teachers and librarians. The results indicated that the two analyzed processes (copyright registration and submission of articles) need improvement. In the case of the registration process, the following needs are: signalizing of the conducting registration ambient; description and exclusion of requested information on the registration form. In the process of article submission, it is emphasized improvement of aspects: the early steps to submission, signaling of required fields, concise description of the steps, minimization and review of the steps. To this end, it is believed that in general idea the SEER partially meets the needs of its users regarding the usability of such software.

A influência das questões de gênero nos processos avaliativos escolares

This paper aims to discuss the influences of gender issues in formal and informal evaluation processes in order to identify situations that may lead to exclusion of boys and girls in our schools. Therefore, we rely on the authors as Freitas (2005, 2006, 2011), Sordi (2009), Villas Boas (2006), Fernandes (2006, 2008), (Carvalho (2001.2004, 2011), Blonde (1995, 2003), Scott (1995), Connell (1995), Navy (2009), Dal'igna (2004), among others. These authors help us understand that both gender issues as the evaluation questions in its formal and informal when analyzed, especially in light of school reality, are impregnated with socially constructed conceptions that are reflected in the school. The survey was conducted in two rooms of the 5th year of elementary school, and the genres of research were qualitative and quantitative. In the development of this study, the research followed those steps: School Rules analysis, grade maps, class journals; Mapping of records of the evaluation results of the 1st to 5th year of elementary school; Analysis of official government documents in education; development, implementation and analysis of questionnaires answered by the students and the teachers with issues about gender and evaluation; Mapping of the evaluation results of the students of two classes surveyed during 2012; Observation in the classroom; interview with the teachers of the surveyed groups. During the research we found that gender issues are not dealt with by the school and that this reinforces some exclusion processes that are linked to these questions. Studies also tell us that on the surveyed groups most of the children who have lower evaluative results are boys, which, in the evaluation of teachers, are considered undisciplined. Of the children with poor results, 50% are black. Some of these children who had low evaluative income have not completed the school year in that school. The study also reveals that on the observed groups, generally the girls have better results in formal assessments than boys, which are considered, by the teachers, more undisciplined and difficult to work with. The girls, on the other hand, are considered more docile and attentive than boys. The observations made by teachers concerning the behavior of boys and girls also reflect in the formal evaluative results, therefore the informal assessments, the value judgment of teachers in relation to the behavior of the students influence the results of formal assessments. In this sense, in order to seek ways to try to overcome the exclusion situations experienced in the evaluation process, we believe that the principles of popular education can be configured as an important parameter to begin discussions on gender and evaluation in schools.

Extensões na arquitetura SDN para o provisionamento de QoS através do monitoramento e uso de múltiplos caminhos

The substantial increase in the number of applications offered through the computer networks, as well as in the volume of traffic forwarded through the network, have hampered to assure adequate service level to users. The Quality of Service (QoS) offer, honoring specified parameters in Service Level Agreements (SLA), established between the service providers and their clients, composes a traditional and extensive computer networks’ research area. Several schemes proposals for the provision of QoS were presented in the last three decades, but the acting scope of these proposals is always limited due to some factors, including the limited development of the network hardware and software, generally belonging to a single manufacturer. The advent of Software Defined Networking (SDN), along with the maturation of its main materialization, the OpenFlow protocol, allowed the decoupling between network hardware and software, through an architecture which provides a control plane and a data plane. This eases the computer networks scenario, allowing that new abstractions are applied in the hardware composing the data plane, through the development of new software pieces which are executed in the control plane. This dissertation investigates the QoS offer through the use and extension of the SDN architecture. Based on the proposal of two new modules, one to perform the data plane monitoring, SDNMon, and the second, MP-ROUTING, developed to determine the use of multiple paths in the forwarding of data referring to a flow, we demonstrated in this work that some QoS metrics specified in the SLAs, such as bandwidth, can be honored. Both modules were implemented and evaluated through a prototype. The evaluation results referring to several aspects of both proposed modules are presented in this dissertation, showing the obtained accuracy of the monitoring module SDNMon and the QoS gains due to the utilization of multiple paths defined by the MP-Routing, when forwarding data flow through the SDN.

O produtor familiar na pecuária leiteira : limites e potencialidades

The technological change is nowadays, comprehended as a playing field which involves cultural and economic processes of appreciation and depreciation of the social aspects of family unit. The exclusion of small producers from the activity is used as an argument to characterize that in the contemporary intercapitalist competition, the family ways of production take up restrict social positions of a technical progress and of a cultural and economic appreciation. The state, a coparcener of the modernization process, has its relevance as a financing agent, a technical capacitor, an infrastructure propitiator, that is, through macro and microeconomic policies which can create sustainable conditions to permit, mainly, not only the family producer to be inserted in the activity, but, above all, to remain in it. This way, this study aims to identify and analyze the family producer, through its limits and potentialities, with a thesis that this would be the main agent responsible for boosting the Brazilian milk production in quantity and quality. Therefore, results were compared obtained from a field survey with data collection via semi-structured open interviews in a sample of 108 producers effectively respondents, namely: 59 family farmers with active DAP (research focus) and 49 employers producers the municipality of Monte Alegre de Minas - MG. Technological indices were used to identify the developmental stage of the producers, thus allowing a comparative study between them. The field research covered all rural municipality of Monte Alegre de Minas – MG and, the result found that the majority of family farmers presented lower rates than technological employers producers. However, it allowed us to state also that the producer family and assisted by public policies, can be the agent of transformation of dairy farming.

ENSINO DO FENÔMENO RELIGIOSO NA ESCOLA PÚBLICA: área de conhecimento necessária para uma sociedade secularizada

Ao estudarmos a evolução histórica e o panorama atual do ensino religioso no Brasil, nos deparamos hoje com o problema da exclusão mútua de duas visões do seu tratamento na escola pública: ou deve existir o ensino religioso confessional ou não deve existir nenhum tipo de ensino religioso. Superando uma visão de laicidade de abstenção ao afirmar que o religioso, por definição, não nos diz respeito ou não diz respeito à ciência, e admitindo uma laicidade de inteligência ao defender que é nosso dever ou dever da ciência compreendê-lo como expressão humana e social, o ensino do fenômeno religioso pode superar essas duas visões, a partir de uma base epistemológica sólida para esta área de conhecimento, como já é prevista pela nossa legislação. Ele garante o respeito à diversidade e à pluralidade cultural da sociedade brasileira e contribui para a compreensão do fenômeno religioso como “objeto de cultura”. Ele é capaz de subsidiar práticas de ensino do fenômeno religioso no sistema de ensino laico, sem prejuízo de sua laicidade, mas a favor dela. A educação laica para a cidadania não pode ignorar as religiões pela sua forte presença e função na sociedade. É preciso decodificar criticamente as representações e práticas religiosas em nome da convivência mais construtiva entre as pessoas e extrair das tradições religiosas valores que contribuam para a vida humana na sua plenitude. Este modelo de ensinar a religião como fenômeno antropológico, social e cultural pode ainda cumprir uma função específica no que se refere ao conhecimento de si mesmo (identidade) e do outro para a aceitação do diferente (alteridade) apontando para a construção de valores éticos e de cidadania. Esta pesquisa se baseia em um grande levantamento bibliográfico e entrevistas com especialistas em laicidade e ensino do religioso a partir da proposta de Régis Debray adotada na França. Ela nos leva a concluir que o ensino do fenômeno religioso na escola pública do Brasil não é apenas necessário, mas até indispensável, se queremos uma educação que contribua para a formação dos nossos alunos e alunas para a convivência solidária.

Individual Proton Pump Inhibitors and Outcomes in Patients With Coronary Artery Disease on Dual Antiplatelet Therapy: A Systematic Review.

BACKGROUND: Observational studies evaluating the possible interaction between proton pump inhibitors (PPIs) and clopidogrel have shown mixed results. We conducted a systematic review comparing the safety of individual PPIs in patients with coronary artery disease taking clopidogrel. METHODS AND RESULTS: Studies performed from January 1995 to December 2013 were screened for inclusion. Data were extracted, and study quality was graded for 34 potential studies. For those studies in which follow-up period, outcomes, and multivariable adjustment were comparable, meta-analysis was performed.The adjusted odds or hazard ratios for the composite of cardiovascular or all-cause death, myocardial infarction, and stroke at 1 year were reported in 6 observational studies with data on individual PPIs. Random-effects meta-analyses of the 6 studies revealed an increased risk for adverse cardiovascular events for those taking pantoprazole (hazard ratio 1.38; 95% CI 1.12-1.70), lansoprazole (hazard ratio 1.29; 95% CI 1.09-1.52), or esomeprazole (hazard ratio 1.27; 95% CI 1.02-1.58) compared with patients on no PPI. This association was not significant for omeprazole (hazard ratio 1.16; 95% CI 0.93-1.44). Sensitivity analyses for the coronary artery disease population (acute coronary syndrome versus mixed) and exclusion of a single study due to heterogeneity of reported results did not have significant influence on the effect estimates for any PPIs. CONCLUSIONS: Several frequently used PPIs previously thought to be safe for concomitant use with clopidogrel were associated with greater risk of adverse cardiovascular events. Although the data are observational, they highlight the need for randomized controlled trials to evaluate the safety of concomitant PPI and clopidogrel use in patients with coronary artery disease.

A transatlantic case: the derivative action as a corporate governance tool

The derivative action as a minority shareholder protection device seems to be almost a dead-letter law in the British Isles as compared with the United States. Whether it can or should be revived through legislative reform and judicial interpretation presents us with important governance questions at first instance, but also raises questions regarding the importance of law, as distinct from non-legally enforceable norms, to the development of corporate governance systems, in particular regarding the director-shareholder relationship.

El Estado y las mujeres, concepciones en clave feminista

Pensar el Estado sigue presentando cierta urgencia en Argentina pues no ha dejado de tener una gran centralidad como interlocutor de las demandas sociales. Específicamente, procuro recuperar los aportes sustantivos de algunas pensadoras feministas. En particular, y aún a riesgo de que mi recorte pueda encasillarse en el de la colonialidad discursiva, retomaré las contribuciones de la politóloga inglesa Carole Pateman y la jurista estadounidense Catharine MacKinnon. Luego, estableceré algunas consideraciones sobre las derivaciones de sus propuestas y la forma en que otras autoras han aportado con particular eje en la ciudadanía tanto en su faz activa como pasiva. Finalmente, volveré a pensar nuestra práctica y nuestra teoría en el proceso de devenir feminista...

Understanding arsenic mobility and speciation in lake sediments impacted by ore roasting near Giant mine, NWT

The roasting of gold-bearing arsenopyrite at Giant mine (Northwest Territories) between 1949 and 1999 released approximately 20,000 tonnes of toxic arsenic-bearing aerosols in the local aerial environment. Detailed examination of lake sediments, sediment porewaters, surface waters and lake hydrology sampled from three lakes of differing limnological characteristics was conducted in summer and winter conditions. Samples were analyzed for solid and dissolved elemental concentrations, speciation and mineralogy. The three lakes are located less than 5km from the mine roaster, and downwind, based on predominant wind direction. The objective of the study was to assess the controls on the mobility and fate of arsenic in these roaster-impacted subarctic lacustrine environments. Results show that the occurrence of arsenic trioxide in lake sediments coincides with the regional onset of industrial activities. The bulk of arsenic in sediments is contained in the form of secondary sulphide precipitates, with iron oxides hosting a minimal amount of arsenic near the surface-water interface. The presence of geogenic arsenic is likely contained as dilute impurities in common rock-forming minerals, and is not believed to be a significant source of arsenic to sediments, porewaters or lake waters. Furthermore, the well correlated depth-profiles of arsenic, antimony and gold in sediments may help reveal roaster impact. The soluble arsenic trioxide particles contained in sediments act as the primary source of arsenic into porewaters. Dissolved arsenic in reducing porewaters both precipitate as secondary sulphides in situ, and diffuse upwards into the overlying lake waters. Arsenic diffusion out of porewaters, combined with watercourse-driven residence time, are estimated to be the predominant mechanisms controlling arsenic concentrations in overlying lake waters. The sequestration of arsenic from porewaters as sulphide precipitates, in the study lakes, is not an effective process in keeping lake-water arsenic concentrations below guidelines for the protection of the freshwater environment and drinking water. Seasonal impacts on lake geochemistry derive from ice covering lake waters, cutting them off from of atmospheric oxygen, along with the exclusion of solutes from the ice. Such effects are limited in deep lakes but are can be an important factor controlling arsenic precipitation and mobility in ponds.

The Brain Drain : Myth and Reality - What it is and What Should be Done (Working Paper 13)

The brain drain debate has been marked by a considerable amount of confusion and frustration, largely because there has been relatively little hard data available, and that which exists has often been twisted into very different forms by those with competing policy agendas. The first goal of this paper is to pull together and summarize the available evidence regarding the size and nature of the outflows, thus establishing an empirical basis from which the issue can be addressed. The second goal is to address some of the major related policy issues. This begins with some general brain drain policy principles. The personal income tax cuts solution is then addressed with simulations of the effects on government revenues and the associated costs “per brain”, thus putting such discussions on a much firmer empirical footing. A number of alternative proposals are then suggested for various problem groups of brain drain workers.

Forging Iconographies and Casting Colonialism: Monuments and Memories in Ontario, 1850-2001

Commemorations are a critical window for exploring the social, political, and cultural trends of a specific time period. Over the past two centuries, the commemorative landscape of Ontario reaffirmed the inclusion/exclusion of particular racial groups. Intended as static markers to the past, monuments in particular visually demonstrated the boundaries of a community and acted as ongoing memorials to existing social structures. Using a specific type of iconography and visual language, the creators of monuments imbued the physical markers of stone and bronze with racialized meanings. As builders were connected with their own time periods and social contexts, the ideas behind these commemorations shifted. Nonetheless, creators were intent on producing a memorial that educated present and future generations on the boundaries of their “imagined communities.” This dissertation considers the carefully chosen iconographies of Ontario’s monuments and how visual symbolism was attached to historical memory. Through the examination of five case studies, this dissertation examines the shifting commemorative landscape of Ontario and how memorials were used to mark the boundaries of communities. By integrating the visual analysis of monuments and related images, it bridges a methodological and theoretical gap between history and art history. This dissertation opens an important dialogue between these fields of study and demonstrates how monuments themselves are critical “documents” of the past.

Pontes para a (Des)inserção: inserção pelo trabalho no Concelho de Stª Mª da Feira

O presente relatório visa a obtenção do grau de Mestre em Serviço Social pelo Instituto Superior Miguel Torga. Motivada pela preocupação nascida na prática profissional quotidiana, no acompanhamento aos cidadãos beneficiários do Rendimento Social de Inserção (R.S.I.), procurámos compreender a relação entre a pobreza e o mercado de trabalho. Criado no ano de 1996 pela Lei nº 19-A/96 de 29 de Junho, como prestação de rendimento mínimo garantido, o R.S.I. tem introduzido formas cada vez mais apuradas de seleção das suas clientelas, quer através da redefinição do conceito de agregado e avaliação dos seus rendimentos, quer da contratualização da prestação, pelo reforço crescente das penalizações ao incumprimento relativo ao emprego e à formação. Objetivo geral é perceber como se efetiva o processo de colocação no mercado de trabalho e que oportunidades de (des)inserção social dai resultam para os beneficiários. Procurámos também analisar a configuração das propostas oferecidas, no âmbito do contrato de inserção, aos homens e às mulheres, aos “velhos” e “novos” pobres. Assim, foram efetuadas entrevistas exploratórias aos técnicos do Centro de Emprego e Formação Profissional Entre Douro e Vouga (CEFP-EDV); Gabinete de Inserção Profissional (GIP) e Núcleo Local de Inserção (NLI) de Stª Mª da Feira e aplicado um inquérito por questionário aos beneficiários do R.S.I. com Contrato de Inserção para colocação no mercado de trabalho. Os técnicos do CEFP-EDV e do GIP expressaram dificuldades no acompanhamento e gestão de carreira dos beneficiários, devido à sobrecarga e à natureza burocrática das tarefas exigidas nos seus organismos. Os beneficiários consideram igualmente que o CEFP-EDV não é eficiente nem eficaz, para a colocação no mercado de trabalho não cumprindo portanto a função que legalmente lhe está atribuída. Os homens são amplamente beneficiados na relação com o Centro de Emprego, comparativamente com as mulheres, porque recebem mais propostas de emprego e formação. A “velha pobreza” aparece instalada no desemprego e na prestação durante mais tempo que os “novos” pobres. Estes raramente são convocados pelo CEFP-EDV. São as redes informais que têm um papel mais ativo e preponderante no processo de inserção laboral. Na população inquirida a inserção pelo trabalho por si só não constituiu a solução para a saída da pobreza. / The present report aims to obtain a Master’s degree in Social Work from the Instituto Superior Miguel Torga. Motivated by concern aroused from the day to day professional practice, while monitoring citizens on social income benefits, “Rendimento Social de Inserção” (R.S.I.) (Social Insertion Income), we have sought to understand the relationship between poverty and the labour market. Introduced in the year 1996 by Law nº 19-A/96 of 29th June, as the provision of income support, the R.S.I. has introduced increasingly more refined forms of selection of its clientele, either by redefining the concept of aggregate and assessmento of their income, or the contractual provision, by increasingly strenthening the penalties for failure in relation to employment and training.The overall goal is to understand how the process of entering the work market is made and the opportunities of (un)inclusion arising from it for the beneficiaries. It was also sought to analyse the configuration of the proposals offered under the insertion contract to men and women, to the “old” and the “new” poor.Consequently, exploratory interviews were made to the technicians of Centro de Emprego e Formação Profissional Entre Douro e Vouga (CEFP-EDV) (Emloyment and Training Centre); Gabinete de Inserção Profissional (GIP) (Professional Insertion Office) and Núcleo Local de Inserção (Local Insertion Group) (NLI) of Stª Mª da Feira. The survey was carried out through a questionnaire to the beneficiaries of the R.S.I. with Insertion Contracts for placement in the labour market.The CEFP-EDV and GIP technicians expressed diffficulties in monitoring and career management of the benefeciaries due to overhead and bureaucratic nature of the tasks recquired in their institutions. The beneficiaries also considered that CEFP-EDV is neither efficient nor effective in placing people in the work market thus not fulfilling the function for which they are legally assigned. Men are largely benefitted in relation to the Job Centre, compared to women, because they get more job offers and training. The “old poverty” appears to be installed in unemployment and provision for longer than the “new” poor. These are rarely called up by CEFP-EDV. It is the informal networks that have a more active and leading role in the process of job placement. For the questioned population entering the job market does not itself constitute a solution to ending poverty.
