O “Oriente” no “Ocidente”: observando o islã no Suriname

Esta dissertação trata do islã surinamês de origem javanesa, distante (não apenas geograficamente) do centro irradiador árabe-islâmico. O Suriname, país sul-americano e caribenho, abriga considerável comunidade muçulmana, a maior em termos percentuais fora da Ásia, África e Europa Oriental. Nele, encontra-se em curso a oposição entre o reformismo e o tradicionalismo no islã. A tendência reformista preza mais por um islã árabe puritano, universalista, com destaque para os valores morais; a tradicional prioriza a comunidade javanesa local e a tradição muçulmana oriunda de Java. A pesquisa envolveu discussões acerca da construção da identidade, da memória à qual os grupos encontram-se vinculados e das “negociações” entre o pertencimento étnico javanês e o pertencimento religioso. Um aspecto que emerge ao longo do trabalho é a diversidade do islã. No Suriname são praticadas cerimônias islâmicas semelhantes às descritas por Clifford Geertz em suas pesquisas realizadas em Java, na década de 1950, como é o caso do slametan, um rito de passagem pós-morte que expressa o momento de transição entre o mundo dos vivos e o dos mortos.

Introducing the CTA concept

The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span about four decades of energy, from a few tens of GeV to above 100 TeV with enhanced angular and energy resolutions over existing VHE gamma-ray observatories. An international collaboration has formed with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America. In 2010 the CTA Consortium completed a Design Study and started a three-year Preparatory Phase which leads to production readiness of CTA in 2014. In this paper we introduce the science goals and the concept of CTA, and provide an overview of the project.

Synthese, Charakterisierung und Testung von Phenylacrylsäure-Derivaten, Benzothiazolen und Diarylthioethern als potentielle Inhibitoren der Dengue-Virus-Typ-2-NS2B-NS3-Protease

Dengue-Fieber ist eine durch Stechmücken der Gattungen Aedes aegypti und Aedes albopticus übertragene, virale Infektionskrankheit des Menschen, welche eine zunehmende Bedrohung für die Weltbevölkerung darstellt; das Infektionsrisiko betrifft vorwiegend Menschen, die in tropischen und subtropischen Gebieten der Erde (Asien, Afrika, Amerika) leben. Bei dem Erreger handelt es sich um ein Flavivirus, bestehend aus einer positiv polarisierten Einzelstrang-RNA, welches in vier verschiedenen Serotypen existiert. Eine Infektion mit Dengue-Viren zeigt sich durch drei mögliche Krankheitsbilder: Klassisches Dengue-Fieber (DF), hämorrhagisches Dengue-Fieber (DHF) oder Dengue-Schock-Syndrom (DSS). Das Dengue-Virus-Genom codiert eine Serin-Protease mit einer klassischen katalytischen Triade, bestehend aus den Aminosäuren His51, Asp75 und Ser135. Die Funktion der Dengue-Virus-Protease besteht in der post-translationalen, proteolytischen Prozessierung des viralen Polyprotein-Vorläufers, womit sie essentiell für die Virus-Replikation ist und damit einen wichtigen therapeutischen Ansatz für die Entwicklung neuer Wirkstoffe gegen Dengue-Fieber darstellt. Die Ziele der vorliegenden Arbeit bestanden darin, neue potentielle Inhibitoren der Dengue-Virus Typ 2 NS2B-NS3 Protease (DEN-2 NS2B-NS3pro) zu synthetisieren, deren Hemmwirkung sowie den Inhibitionstyp mithilfe fluorimetrischer Enzym-Assays zu bestimmen, Struktur-Wirkungs-Beziehungen (u.a. mithilfe von Molecular Docking-Rechnungen) zu analysieren und die erhaltenen Leitstrukturen zu optimieren. In der vorliegenden Arbeit wurden zwei Substanzklassen und damit zwei Teilprojekte behandelt: Phenylacrylsäureamide im ersten Teilprojekt, Benzothiazole und Diarylthioether zusammen im zweiten Teilprojekt. Im ersten Teilprojekt zeigten einige Phenylacrylsäureamide eine schwache Hemmung der DEN-2 NS2B-NS3pro zwischen ca. 50 und 61 % bei einer Inhibitorkonzentration von 50 µM sowie eine nicht-kompetitive Hemmung, welche jedoch durch vielfältige Derivatisierung kaum verändert oder verbessert werden konnte. Darüber hinaus wurden die endogenen Serin-Proteasen alpha-Chymotrypsin und Trypsin durch einige Phenylacrylsäureamide erheblich stärker gehemmt als die DEN-2 NS2B-NS3pro. Das zweite Teilprojekt befasste sich mit der Synthese und Testung von Diarylthioethern mit hydroxy-substituierten Benzothiazol-Bausteinen sowie der Testung einiger methoxy-substituierter Synthese-Vorstufen der Endverbindungen, um die Relevanz und den Einfluss der einzelnen Bausteine auf die Hemmung der DEN-2 NS2B-NS3pro zu untersuchen. Der in der vorliegenden Arbeit synthetisierte, potenteste Inhibitor der DEN-2 NS2B-NS3pro (Hemmung: 90 % [50 µM]; IC50 = 3.6 +/- 0.11 µM) und der DEN-3 NS2B-NS3pro (Hemmung: >99 % [100 µM]; IC50 = 9.1 +/- 1.02 µM), SH65, ein Diarylthioether-Benzothiazol-Derivat, entstand aufgrund der Vorhersage zweier möglicher Bindungsmodi (kompetitiv und nicht-kompetitiv) mithilfe von Molecular Docking-Experimenten an der Röntgen-Kristall-struktur der DEN-3 NS2B-NS3pro (PDB-Code: 3U1I). Nach experimenteller Bestimmung der IC50-Werte bei unterschiedlichen Substratkonzentrationen erwies sich SH65 jedoch als nicht-kompetitiver Inhibitor der DEN-2 NS2B-NS3pro. Trypsin wurde von SH65 vergleichbar stark gehemmt (96% [50 µM]; IC50 = 6.27 +/- 0.68 µM) wie die beiden getesteten Dengue-Virus-Proteasen, nicht jedoch alpha-Chymotrypsin (nur 21% Hemmung bei 50 µM), wodurch diesem Inhibitor zumindest eine relative Selektivität gegenüber Serin-Proteasen zugeschrieben werden kann. SH65 zeigte lediglich Protease-Hemmung in den Enzym-Assays, jedoch keine antivirale Aktivität bei der Testung an Dengue-Virus-infizierten Zellen, was aber wiederum bei der synthetisierten Vorstufe von SH65, welche anstelle der beiden Hydroxy-Gruppen über Methoxy-Gruppen verfügt, der Fall war. Diarylthioether mit mehrfach hydroxy-substituiertem Benzothiazol-Baustein stellen hiermit eine neue, vielversprechende Wirkstoffgruppe zur Hemmung sowohl der Dengue-Virus Typ 2- als auch der Dengue-Virus Typ 3 NS2B-NS3 Protease dar.

Training in Mental Health: Evaluation of the Telephone Conference Network

The Telephone Conference Network, sponsored by The Pennsylvania State University's Coordinating Council for Health Care, is designed as a cost-effective format for providing inservice training in geriatric mental health for individuals who serve the elderly. Institutions which subscribe to the Telephone Conference Network are equipped with a conference speaker and telephone hook-up providing a two-way line of communication, and may choose from a variety of inservice programs. Mailed evaluations were completed by participants (N=73) in the "Skills to Manage Moods" program, a series of four 1-hour sessions designed to teach participants the skills needed to help patients cope with depression and to deliver the program to others. The majority of respondents reported high levels of satisfaction with the Telephone Conference Network system and the specific program in which they participated. Although 85 percent reported that they would be able to use the skills learned in the program on the job, 50 percent reported that they would not be interested in teaching these skills to others. The convenience and efficiency of the Telephone Conference Network were the most frequently mentioned strengths of the system, while the physical facilities and the program delivery format adopted by the individual institutions were the most frequently mentioned weaknesses. These data suggested several recommendations for Network subscribers and for professionals offering telephone conference programs, including ensuring optimal class enrollment and adequate physical facilities, and participant involvement in program implementation.

Towards a Swiss National Research Infrastructure

In this position paper, we describe the current status and plans for a Swiss National Research Infrastructure. Swiss academic and research institutions are very autonomous. While being loosely coupled, they do not rely on any centralized management entities. A coordinated national research infrastructure can only be established by federating the local resources of the individual institutions. We discuss current efforts and business models for a federated infrastructure.

Legislation on violence against women: overview of key components

This study aimed to determine if legislation on violence against women (VAW) worldwide contains key components recommended by the Pan American Health Organization (PAHO) and the United Nations (UN) to help strengthen VAW prevention and provide better integrated victim protection, support, and care. A systematic search for VAW legislation using international legal databases and other electronic sources plus data from previous research identified 124 countries/territories with some type of VAW legislation. Full legal texts were found for legislation from 104 countries/territories. Those available in English, Portuguese, and Spanish were downloaded and compiled and the selection criteria applied (use of any of the common terms related to VAW, including intimate partner violence (IPV), and reference to at least two of six sectors (education, health, judicial system, mass media, police, and social services) with regard to VAW interventions (protection, support, and care). A final sample from 80 countries/territories was selected and analyzed for the presence of key components recommended by PAHO and the UN (reference to the term "violence against women" in the title; definitions of different types of VAW; identification of women as beneficiaries; and promotion of (reference to) the participation of multiple sectors in VAW interventions). Few countries/territories specifically identified women as the beneficiaries of their VAW legislation, including those that labeled their legislation "domestic violence" law ( n = 51), of which only two explicitly mentioned women as complainants/survivors. Only 28 countries/territories defined the main forms of VAW (economic, physical, psychological, and sexual) in their VAW legislation. Most highlighted the role of the judicial system, followed by that of social services and the police. Only 28 mentioned the health sector. Despite considerable efforts worldwide to strengthen VAW legislation, most VAW laws do not incorporate the key recommended components. Significant limitations were found in the legislative content, its application, and the extent to which it provided women with integrated protection, support, and care. In developing new VAW legislation, policymakers should consider the vital role of health services.

Fine-tuning the use of bail-in to promote a stronger EU financial system. CEPS Special Report No. 136/April 2016

This paper discusses the application of the new European rules for burden-sharing and bail-in in the banking sector, in view of their ability to accommodate broader policy goals of aggregate financial stability. It finds that the Treaty principles and the new discipline of state aid and the restructuring of banks provide a solid framework for combating moral hazard and removing incentives that encourage excessive risk-taking by bankers. However, the application of the new rules may have become excessively attentive to the case-by-case evaluation of individual institutions, while perhaps losing sight of the aggregate policy needs of the banking system. Indeed, in this first phase of the banking union, while large segments of the EU banking sector still require a substantial restructuring and recapitalisation, the market may not be able to provide all the needed resources in the current environment of depressed profitability and low growth. Thus, a systemic market failure may be making the problem impossible to fix without resorting to temporary public support. But the risk of large write-offs of capital instruments due to burden-sharing and bail-in may represent an insurmountable obstacle to such public support as it may set in motion an investors’ flight. The paper concludes by showing that existing rules do contain the flexibility required to accommodate aggregate policy requirements in the general interest, and outlines a public support scheme for the precautionary recapitalisation of solvent banks that would be compliant with EU law.

Trade and culture history across the Vitiaz Strait, Papua New Guinea: The emerging post-Lapita coastal sequence

This paper, focusing principally on post-Lapita times, outlines the course and outcomes of work undertaken over the last two decades in the West New Britain-Vitiaz Strait-north New Guinea coastal region. It presents two principal arguments. The first is that major periods of movement and abandonment documented in the archaeological sequences of this region from about 3,500 years ago coincide with the record of volcanism in the Talasea-Cape Hoskins area. The second is that the post-Lapita sequences of this region differ significantly from the post-Lapita sequences emerging in the island arc reaching from Manus via New Ireland to southern and eastern island Melanesia, which show continuous occupation and pottery production.

ICP-MS Trace Element Analysis of Song Dynasty Porcelains from Ding, Jiexiu and Guantai kilns, North China

Bodies of Ding kiln white porcelains and their imitations from Guantai and Jiexiu kilns of the Chinese Song dynasty (960-1279 AD) were analysed for 40 trace elements by inductively coupled plasma mass spectrometry (ICP-MS). Numerous trace element compositions and ratios allow these visually similar products to be distinguished, and a Ding-style shard of uncertain origin is identified as a likely genuine Ding product. In Jiexiu kiln, Ding-style products have trace element features distinctive from blackwares of an inferior quality intended for the lower end market. Based on geochemical behaviour of these trace elements, we propose that geochemically distinctive raw materials were used for Ding-style products of a higher quality, which possibly also underwent purification by levigation prior to use. Capable of analysing over 40 elements with a typical long term precision of < 2%, this high precision ICP-MS method proves to be very powerful for grouping and characterising archaeological ceramics. Combined with geochemical interpretation, it can provide insights into the raw materials and techniques used by ancient potters. (C) 2004 Elsevier Ltd. All rights reserved.

A short note on starch and xylem of Colocasia esculenta (taro) in archaeological deposits from Pitcairn Island, southeast Polynesia

We present results of starch analysis of archaeological deposits from Pitcairn Island. High concentrations of starch grains preserved in cell membranes, and xylem tracheary elements, consistent with introduced Colocasia esculenta (taro) were found. Because of limited age control, we are uncertain if the microfossils are prehistoric. Problems associated with identifying taxa with small starch grains in extractions from weathered deposits are highlighted. (c) 2006 Elsevier Ltd. All rights reserved.
