Dominância política e paralisia executiva

Desde 2014 nossas análises têm enfatizado o vínculo entre a política e a economia para explicar a crise pela qual o país passa desde então. De um lado, a falta de consenso político tem impedido respostas mais fortes ao quadro de deterioração fiscal. Isso derrubou a confiança de empresários e consumidores, levando junto o nível de atividade e, em um círculo vicioso, as receitas tributárias, dessa forma agravando ainda mais o quadro fiscal. De outro lado, a deterioração econômica enfraqueceu a disposição dos políticos, a começar pelo próprio Executivo, de adotar medidas mais fortes na área fiscal, levando a um quadro de quase inércia na política econômica.

O DEBATE SOBRE A HISTÓRIA DAS ORIGENS DO TRABALHO BATISTA NO BRASIL Uma análise das relações e dos conflitos de gênero e poder na Convenção Batista Brasileira dos anos 1960-1980

O presente trabalho analisou as relações e os conflitos de gênero e poder observados durante o debate sobre as origens do trabalho batista no Brasil, debate esse entre o Pastor José dos Reis Pereira, líder oficial da Convenção Batista Brasileira durante os anos 1960-1980 e a pesquisadora batista Betty Antunes de Oliveira. A análise do conflito foi realizada principalmente com a mediação de gênero como instrumento hermenêutico, conforme os pressupostos de Joan Wallach Scott. Desse modo, a pesquisa teve como propósito principal, a partir da análise do debate, dar visibilidade ao conflito de gênero nos lugares de poder da Convenção Batista Brasileira dos anos 1960-1980, conflito dissimulado pelos discursos batistas sobre direitos de liberdade e igualdade sociais. Esta pesquisa trabalhou basicamente com as seguintes hipóteses: a dinâmica do debate foi fortalecida pelo contexto sociopolítico daqueles anos, que favoreceu a emergência dos movimentos de mulheres e feminista no Brasil, cujas influências foram também sentidas em outras tradições de fé cristã; e o resultado final do debate dependeu mais das questões de gênero e poder do que das discussões técnicas e acadêmicas sobre o acerto histórico do marco inicial do trabalho batista no Brasil. O ineditismo desta pesquisa está em oferecer uma nova perspectiva do debate sobre as origens do trabalho batista no Brasil, a partir do uso da categoria de gênero como instrumento de análise, o que complementará, desse modo, a pesquisa acadêmica já publicada sobre o tema.

Semantikos: proposta de interfaces para aplicativo mediador de técnica de diferencial semântico em mobile tablet

This research aims to systematize a proposal of developing a mobile tablet application in order to help implementing the Semantic Differential technique – SD, under the approach of Participatory Design. In 1975, Osgood et al. created the Semantic Differential technique. Since then, many experiments use it to measure the affective perception of individuals concerning objects and concepts by means of compounded scales of bipolar adjectives, based on the theoretical models that support the technique: the conductible, spatial and metric models. During the application of the technique with potential users, the researcher must simultaneously manage several contexts, that is, audio recorder, when authorized, and observe and record spontaneous reports of the respondent. It is noticeable that often occurs a cognitive overload during this event. Thus, the use of a single application whose interface is assigned to its users and respondents could assist researchers in applying the SD technique. This research aimed to understand the processes inherent to the task of implementing the Semantic Differential technique and obeyed the following steps: a) training of users, b) background questionnaire c) interview with Focus Group, and d) cooperative evaluation. Besides these procedures, one can also observe the degrees of facilitation or difficulty concerning the use of the conventional model, which is the development and application of scales with the aid of printed material, pencil, pens, clipboards, and recorder software for editing the document and data analysis. This paper comprises reactions and impressions from the experiences of users of SD technique. Considering the data recollected from the user’s observation, the hypothesis of the experiment proved to be right. It means that the development of the application for mobile tablet employing the technique of Semantic Differential is viable, since it assembles all the steps in one only tool, increases the accomplishment of the task between user/researcher and user/respondent resulting in their mutual satisfaction.

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.

Recomendações para um sistema de sinalização tátil a partir de abordagens ergonômicas e da percepção do deficiente visual para o Campus Parnamirim do IFRN

This study reports recommendations for a tactile and graphic wayfinding system aiming to offer more orientability and mobility for visually impaired people (blindness and low vision) at Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN), Parnamirim Campus. It was necessary to focus on visual impaired people and approach concepts like orientation and accessibility at the built environment. In order to provide the comprehension of a complex social phenomenon and preserve the meaningful characteristics of the events, this research has developed a single case study in which elements of Post Occupation Evaluation have been used. Its purpose was to allow not only a technical analysis, but also the user perception about the space in use. The chosen tool to collect the user’s opinions and considerations was the Walk Together Method. The collected and analyzed information has demonstrated that, although Parnamirim Campus has implemented some interventions in relation to the spatial accessibility, they are still not enough to create an environment which arranges safety and autonomy for the visual impaired people and the other ones who attend there. This study suggests that it happened because the engineering interventions at the Campus have been based on Brazilian technical standards NBR 9050:2004, which is proper for the physical impaired people, but it does not offer enough information to respond to all the specific needs demanded by all the classifications of visual impairment.

Madeira wine vinification process: analysis and control

The present study was done in collaboration with J. Faria e Filhos company, a Madeira wine producer, and its main goal was to fully characterize three wines produced during 2014 harvest and identify possible improving points in the winemaking process. The winemaking process was followed during 4 weeks, being registered the amounts of grapes received, the fermentation temperatures, the time at which fermentation was stopped and evolution of must densities until the fortification time. The characterization of musts and wines was done in terms of density, total and volatile acidity, alcohol content, pH, total of polyphenol, organic acids composition, sugars concentration and the volatile profile. Also, it was developed and validated an analytical methodology to quantify the volatile fatty acids, namely using SPME-GC-MS. Briefly, the following key features were obtained for the latter methodology: linearity (R2=0.999) e high sensitivity (LOD =0.026-0.068 mg/L), suitable precision (repeatability and reproducibility lower than 8,5%) and good recoveries (103,11-119,46%). The results reveal that fermentation temperatures should be controlled in a more strictly manner, in order to ensure a better balance in proportion of some volatile compounds, namely the esters and higher alcohols and to minimize the concentration of some volatiles, namely hexanoic, octanoic and decanoic acids, that when above their odours threshold are not positive for the wine aroma. Also, regarding the moment to stop the fermentation, it was verified that it can be introduced changes which can also be benefit to guarantee the tipicity of Madeira wine bouquet.

Simulação de sistemas solares passivos usando materiais de mudança de fase (PCMs)

O gradual consumo de energia primária a nível mundial deu origem a uma crise não só ambiental como também económica, proveniente das limitações das reservas energéticas e do fornecimento. Estas inquietações têm levado a um estudo cada vez mais aprofundado no que concerne à eficiência energética de edifícios. É neste contexto que surge o estudo da aplicação dos materiais de mudança de fase (PCM) na térmica dos edifícios. O presente trabalho consiste no estudo da influência da introdução de materiais de mudança de fase no comportamento térmico de um edifício. Foi analisada uma simulação numérica para um sistema solar passivo de ganho direto, por um programa de simulação designado EXTEND™. Efetuou-se, também, o estudo paramétrico de determinadas propriedades associadas aos materiais de mudança de fase. Após a análise, foi testado o impacto, em termos de conforto, da utilização de materiais de mudança de fase em sistemas solares passivos de ganho direto.

Ferulates and lignin structural composition in cork

The structure of lignin and suberin, and ferulic acid (FA) content in cork from Quercus suber L. were studied. Extractive-free cork (Cork), suberin, desuberized cork (Cork(sap)), and milled-cork lignins (MCL) from Cork and Cork(sap) were isolated. Suberin composition was determined by GC-MS/FID, whereas the polymers structure in Cork, Corksap, and MCL was studied by Py-TMAH and 2D-HSQC-NMR. Suberin contained 94.4% of aliphatics and 3.2% of phenolics, with 90% of omega-hydroxyacids and alpha,omega-diacids. FA represented 2.7% of the suberin monomers, overwhelmingly esterified to the cork matrix. Py-TMAH revealed significant FA amounts in all samples, with about 3% and 6% in cork and cork lignins, respectively. Py-TMAH and 2D-HSQC-NMR demonstrated that cork lignin is a G-lignin (>96% G units), with a structure dominated by beta-O-4' alkyl-aryl ether linkages (80% and 77% of all linkages in MCL and MCLsap, respectively), followed by phenylcoumarans (18% and 20% in MCL and MCLsap, respectively), and smaller amounts of resinols (ca. 2%) and dibenzodioxocins (1%). HSQC also revealed that cork lignin is heavily acylated (ca. 50%) exclusively at the side-chain gamma-position. Ferulates possibly have an important function in the chemical assembly of cork cell walls with a cross-linking role between suberin, lignin and carbohydrates.

Lake Inaha 217971

This vessel was built at Lorain, Ohio in 1919 by the American Ship Building Company. Until 1930, she was owned by the U. S. Shipping Board of Washington, D. C. That year she was sold to the Ford Motor Company. In 1943, she once again was owned by the U.S. Shipping Board. In 1946, she was purchased by the Bright Star Steamship Company of Washington, Panama. Her name was changed to "Captain John." From 1951 to 1954, she was owned by Navebras of Rio de Janeiro, Brazil. Her name was then changed to "Santa Martha." In 1954, she foundered off the coast of Brazil.
