LAICIDADE E ECUMENICIDADE DA IGREJA O Pensamento Eclesiológico de John Wesley

A presente investigação se concentra na eclesiologia prática, experimental e funcional de John Wesley, examinando não apenas o que se encontra explícito em seus escritos sobre a igreja, mas também o que está implícito na práxis social e missionária dos primeiros metodistas. Antes, porém, é traçado um panorama das discussões em torno da concepção wesleyana de igreja, desenvolvidas, sobretudo, nos últimos cinqüenta anos. O valor dessas pesquisas é reconhecido, pois elas ajudaram a criar certa convergência em torno dos principais temas da visão de Wesley. Entretanto, em boa parte delas, nota-se esforço em enquadrar a fragmentada reflexão wesleyana em algum esquema de interpretação previamente definido. De conservador e defensor da Igreja estabelecida a cismático radical, quase todas as qualificações lhe foram atribuídas. É certo que Wesley assimilou a contribuição de várias correntes, o que oferece justa dimensão da complexidade de sua teologia, resistente a explicações simplistas. Nem sempre, porém, se indaga sobre o que determinou as suas preferências. Aqui é sustentada a tese de que não foi o apego a princípios considerados ortodoxos, mas o encontro com o povo que levou Wesley à abertura crescente para uma compreensão da igreja, ao mesmo, sensível ao sofrimento dos excluídos da sociedade inglesa, e flexível para se ajustar a conjunturas em mutação constante. Ele rompeu com a eclesiologia hierárquica, em que foi formado, e pôs em prática uma concepção fundamentalmente laica de igreja. Quebrou o monopólio do clero e tornou realidade o sacerdócio de todos os crentes, tanto de homens quanto de mulheres. Rejeitou o individualismo e valorizou a vida comunitária responsável. Desfez a interpretação paroquialista e exclusivista de igreja e abraçou a ecumenicidade como caráter essencial da Igreja de Cristo. Enfim, centralizou-se na via salutis, na renovação de toda a criação, pela graça de Deus com a participação humana responsável, e relativizou a própria Igreja.

Invariance under type morphisms: the bayesian Nash equilibrium

Ely and Peski (2006) and Friedenberg and Meier (2010) provide examples when changing the type space behind a game, taking a "bigger" type space, induces changes of Bayesian Nash Equilibria, in other words, the Bayesian Nash Equilibrium is not invariant under type morphisms. In this paper we introduce the notion of strong type morphism. Strong type morphisms are stronger than ordinary and conditional type morphisms (Ely and Peski, 2006), and we show that Bayesian Nash Equilibria are not invariant under strong type morphisms either. We present our results in a very simple, finite setting, and conclude that there is no chance to get reasonable assumptions for Bayesian Nash Equilibria to be invariant under any kind of reasonable type morphisms.

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.

Thrombolysis in myocardial infarction risk score in an observation unit setting.

OBJECTIVE: The Thrombolysis in Myocardial Infarction (TIMI) score is a validated tool for risk stratification of acute coronary syndrome. We hypothesized that the TIMI risk score would be able to risk stratify patients in observation unit for acute coronary syndrome. METHODS: STUDY DESIGN: Retrospective cohort study of consecutive adult patients placed in an urban academic hospital emergency department observation unit with an average annual census of 65,000 between 2004 and 2007. Exclusion criteria included elevated initial cardiac biomarkers, ST segment changes on ECG, unstable vital signs, or unstable arrhythmias. A composite of significant coronary artery disease (CAD) indicators, including diagnosis of myocardial infarction, percutaneous coronary intervention, coronary artery bypass surgery, or death within 30 days and 1 year, were abstracted via chart review and financial record query. The entire cohort was stratified by TIMI risk scores (0-7) and composite event rates with 95% confidence interval were calculated. RESULTS: In total 2228 patients were analyzed. Average age was 54.5 years, 42.0% were male. The overall median TIMI risk score was 1. Eighty (3.6%) patients had 30-day and 119 (5.3%) had 1-year CAD indicators. There was a trend toward increasing rate of composite CAD indicators at 30 days and 1 year with increasing TIMI score, ranging from a 1.2% event rate at 30 days and 1.9% at 1 year for TIMI score of 0 and 12.5% at 30 days and 21.4% at 1 year for TIMI ≥ 4. CONCLUSIONS: In an observation unit cohort, the TIMI risk score is able to risk stratify patients into low-, moderate-, and high-risk groups.

Discourse on equality in organizations. A case study of the chemical industry in Tarragona

This paper presents a proposal for analyzing discourses on gender equality in organizations. The research is carried out as a case study, focusing on the chemical industry in Tarragona. To the question: why there are still so many differences between women and men in labour market, despite having multiple tools to avoid inequalities? we propose to focus on discourses of equality to find an answer. The viewpoint that companies have on gender is crucial in enabling policies for equality. To ensure that policies are truly aimed at promoting equality, it is needed a gender approach that nowadays is not widespread in organizations. From these considerations, we present a fourfold typology of discourses on equality in organizations.

Assessing the Societal Impact of Research: The Relational Engagement Approach

Marketing and policy researchers seeking to increase the societal impact of their scholarship should engage directly with relevant stakeholders. For maximum societal effect, this engagement needs to occur both within the research process and throughout the complex process of knowledge transfer. A relational engagement approach to research impact is proposed as complementary and building upon traditional approaches. Traditional approaches to impact employ bibliometric measures and focus on the creation and use of journal articles by scholarly audiences, an important but incomplete part of the academic process. The authors suggest expanding the strategies and measures of impact to include process assessments for specific stakeholders across the entire course of impact: from the creation, awareness, and use of knowledge to societal impact. This relational engagement approach involves the co-creation of research with audiences beyond academia. The authors hope to begin a dialogue on the strategies researchers can make to increase the potential societal benefits of their research.

Using UAV acquired photography and structure from motion techniques for studying glacier landforms: application to the glacial flutes at Isfallsglaciären

Glacier and ice sheet retreat exposes freshly deglaciated terrain which often contains small-scale fragile geomorphological features which could provide insight into subglacial or submarginal processes. Subaerial exposure results in potentially rapid landscape modification or even disappearance of the minor–relief landforms as wind, weather, water and vegetation impacts on the newly exposed surface. Ongoing retreat of many ice masses means there is a growing opportunity to obtain high resolution geospatial data from glacier forelands to aid in the understanding of recent subglacial and submarginal processes. Here we used an unmanned aerial vehicle to capture close-range aerial photography of the foreland of Isfallsglaciären, a small polythermal glacier situated in Swedish Lapland. An orthophoto and a digital elevation model with ~2 cm horizontal resolution were created from this photography using structure from motion software. These geospatial data was used to create a geomorphological map of the foreland, documenting moraines, fans, channels and flutes. The unprecedented resolution of the data enabled us to derive morphological metrics (length, width and relief) of the smallest flutes, which is not possible with other data products normally used for glacial landform metrics mapping. The map and flute metrics compare well with previous studies, highlighting the potential of this technique for rapidly documenting glacier foreland geomorphology at an unprecedented scale and resolution. The vast majority of flutes were found to have an associated stoss-side boulder, with the remainder having a likely explanation for boulder absence (burial or erosion). Furthermore, the size of this boulder was found to strongly correlate with the width and relief of the lee-side flute. This is consistent with the lee-side cavity infill model of flute formation. Whether this model is applicable to all flutes, or multiple mechanisms are required, awaits further study.

Effect of intravenous haloperidol on the duration of delirium and coma in critically ill patients (Hope-ICU):A randomised, double-blind, placebo-controlled trial

Background: Delirium is frequently diagnosed in critically ill patients and is associated with poor clinical outcomes. Haloperidol is the most commonly used drug for delirium despite little evidence of its effectiveness. The aim of this study was to establish whether early treatment with haloperidol would decrease the time that survivors of critical illness spent in delirium or coma. Methods: We did this double-blind, placebo-controlled randomised trial in a general adult intensive care unit (ICU). Critically ill patients (≥18 years) needing mechanical ventilation within 72 h of admission were enrolled. Patients were randomised (by an independent nurse, in 1:1 ratio, with permuted block size of four and six, using a centralised, secure web-based randomisation service) to receive haloperidol 2·5 mg or 0·9% saline placebo intravenously every 8 h, irrespective of coma or delirium status. Study drug was discontinued on ICU discharge, once delirium-free and coma-free for 2 consecutive days, or after a maximum of 14 days of treatment, whichever came first. Delirium was assessed using the confusion assessment method for the ICU (CAM-ICU). The primary outcome was delirium-free and coma-free days, defined as the number of days in the first 14 days after randomisation during which the patient was alive without delirium and not in coma from any cause. Patients who died within the 14 day study period were recorded as having 0 days free of delirium and coma. ICU clinical and research staff and patients were masked to treatment throughout the study. Analyses were by intention to treat. This trial is registered with the International Standard Randomised Controlled Trial Registry, number ISRCTN83567338. Findings: 142 patients were randomised, 141 were included in the final analysis (71 haloperidol, 70 placebo). Patients in the haloperidol group spent about the same number of days alive, without delirium, and without coma as did patients in the placebo group (median 5 days [IQR 0-10] vs 6 days [0-11] days; p=0·53). The most common adverse events were oversedation (11 patients in the haloperidol group vs six in the placebo group) and QTc prolongation (seven patients in the haloperidol group vs six in the placebo group). No patient had a serious adverse event related to the study drug. Interpretation: These results do not support the hypothesis that haloperidol modifies duration of delirium in critically ill patients. Although haloperidol can be used safely in this population of patients, pending the results of trials in progress, the use of intravenous haloperidol should be reserved for short-term management of acute agitation.

Ciclos econômicos e emissão de CO2 no Brasil: uma análise dinâmica para políticas ambientais ótimas

Este artigo estuda como as políticas ambientais devem responder de forma ótima aos ciclos econômicos no Brasil. Para isso utilizamos um modelo de ciclos reais de negócios (RBC) com externalidades de poluição. Os resultados indicam que o custo de mitigação de emissões de carbono é mais baixo que o da poluição no Brasil, justificando a adoção de políticas restritivas. Além disso, diante de choques de produtividade, o comportamento ótimo é uma política de mitigação pró-cíclica, onde o imposto e o teto de emissões devem aumentar em períodos de expansão da economia e diminuir em períodos de crise. Também definimos uma regra de decisão para a dinâmica da política de mitigação.

Functional characterization by genetic complementation of aroB-Encoded dehydroquinate synthase from Mycobactetium tuberculosis H37Rv and its heterologous expression and purification

The recent recrudescence of Mycobacterium tuberculosis infection and the emergence of multidrug-resistant strains have created an urgent need for new therapeutics against tuberculosis. The enzymes of the shikimate pathway are attractive drug targets because this route is absent in mammals and, in M. tuberculosis, it is essential for pathogen viability. This pathway leads to the biosynthesis of aromatic compounds, including aromatic amino acids, and it is found in plants, fungi, bacteria, and apicomplexan parasites. The aroB-encoded enzyme dehydroquinate synthase is the second enzyme of this pathway, and it catalyzes the cyclization of 3-deoxy-D-arabino-heptulosonate-7-phosphate in 3-dehydroquinate. Here we describe the PCR amplification and cloning of the aroB gene and the overexpression and purification of its product, dehydroquinate synthase, to homogeneity. In order to probe where the recombinant dehydroquinate synthase was active, genetic complementation studies were performed. The Escherichia coli AB2847 mutant was used to demonstrate that the plasmid construction was able to repair the mutants, allowing them to grow in minimal medium devoid of aromatic compound supplementation. In addition, homogeneous recombinant M. tuberculosis dehydroquinate synthase was active in the absence of other enzymes, showing that it is homomeric. These results will support the structural studies with M. tuberculosis dehydroquinate synthase that are essential for the rational design of antimycobacterial agents.
