Um dos principais desafios em Redes Centradas em Informação (ICN) é como prover controle de acesso à publicação e recuperação de conteúdos. Apesar das potencialidades, as soluções existentes, geralmente, consideram um único usuário agindo como publicador. Ao lidar com múltiplos publicadores, elas podem levar a uma explosão combinatória de chaves criptográficas. As soluções projetadas visando a múltiplos publicadores, por sua vez, dependem de arquiteturas de redes específicas e/ou de mudanças nessas para operar. Nesta dissertação é proposta uma solução, apoiada em criptografia baseada em atributos, para controle de acesso a conteúdos. Nessa solução, o modelo de segurança é voltado a grupos de compartilhamento seguro, nos quais todos os usuários membros podem publicar e consumir conteúdos. Diferente de trabalhos anteriores, a solução proposta mantém o número de chaves proporcional ao de membros nos grupos e pode ser empregada em qualquer arquitetura ICN de forma gradual. A proposta é avaliada quanto ao custo de operação, à quantidade de chaves necessárias e à eficiência na disseminação de conteúdos. Em comparação às soluções existentes, ela oferece maior flexibilidade no controle de acesso, sem aumentar a complexidade do gerenciamento de chaves e sem causar sobrecustos significativos à rede. / One of the main challenges in Information-Centric Networking (ICN) is providing access control to content publication and retrieval. In spite of the potentialities, existing solutions often consider a single user acting as publisher. When dealing with multiple publishers, they may lead to a combinatorial explosion of cryptographic keys. Those solutions that focus on multiple publishers, on the other hand, rely on specific network architectures and/or changes to operate. In this dissertation, it is proposed a solution, supported by attribute-based encryption, for content access control. In this solution, the security model is focused on secure content distribution groups, in which any member user can publish to and retrieve from. Unlike previous work, the proposed solution keeps the number of cryptographic keys proportional to the number of group members, and may even be adopted gradually in any ICN architecture. The proposed solution is evaluated with respect to the overhead it imposes, number of required keys, and efficiency in the content dissemination. In contrast to existing solutions, it offers higher access control flexibility, without increasing key management process complexity and without causing significant network overhead.

A presente pesquisa tem como intuito estabelecer um olhar sobre a produção de periódicos alternativos no campo das artes, que passaram a servir como suporte e como meio para muitos artistas veicularem suas poéticas e seus discursos a partir dos anos 1960 e 70. Associados ao estouro da comunicação, à busca por liberdades estéticas e às reivindicações sociopolíticas, o formato editorial em série propagou-se em contexto nacional e internacional, possibilitando trocas e diálogos entre distintas regiões. A atual pesquisa procurou dar destaque à produção brasileira dos anos 1970, tendo como objeto de análise os cartazetes periódicos Nervo Óptico, de Porto Alegre, criados por um grupo de artistas da cidade, entre eles, Vera Chaves Barcellos, e a revista Punho, de Recife, também produção coletiva de artistas e escritores, da qual Paulo Bruscky era o principal idealizador. Pretende-se com esse estudo, além de alcançar um melhor entendimento específico acerca dessas poéticas e suas conexões e abrir caminho para a compreensão de alguns fenômenos similares, perceber a importância do impresso como espaço de expressão e como prática participativa da edificação do pensamento contemporâneo. / This research is meant to provide a glimpse into the alternative periodicals production in the art field, which served as support and as media for many artists to transmit their poetry and speeches from the 1960s and 70s. Related to burst communication, the search for aesthetic liberties and socio-political demands, the editorial format in series spreads in national and international context, making possible exchanges and dialogues between different regions. The current research sought to highlight the Brazilian production of the 1970s, with the object of analysis Periodicals cartazetes Optic Nerve, of Porto Alegre, created by a group of city artists, among them Vera Chaves Barcellos, and handle magazine from Recife also collective production of artists and writers, that Paul Bruscky was the main proponent. The aim of this study, in addition to achieve a better understanding of these specific poetic and their connections, realize the importance of printed as a space for expression and as participatory practice of building of contemporary thought.

Pain measurement in Intensive Care Units has received more notoriety just recently due to the need of developing new pharmacological methods and improving pain assessment in critically ill subjects. This assessment can be performed based on validated instruments as the Behavioral Pain Scale (BPS). The difficulty for patients using artificial airway to communicate and the absence of a Brazilian version of a scale for pain assessment in adults mechanically ventilated justifies the relevance of this study that aimed to validate the Brazilian version of BPS as well as to correlate the scores of this scale with the records of physiological parameters, sedation level and disease of this sample. This observational study was conducted in the cardiologic ICU at the Hospital de Cirurgia in Aracaju-Sergipe-Brazil from February to August 2014. Twenty five sedated or unconscious adult patients connected to an artificial airway who were using mechanical ventilation were included in this study. The Brazilian BPS version and the recording of heart rate, blood pressure and peripheral oxygen saturation were performed by two independent investigators simultaneously during three different moments: at rest, during eye cleaning (non-painful stimulus) and during tracheal aspiration (painful stimulus). Other variables as sedation level and severity of disease were recorded by using the Ramsay Scale, Richmond Agitation Sedation Scale (RASS) and APACHE II (Acute Physiology Health Chronic Evaluation) score respectively. The intake of sedative and analgesic medicines during patient assessment was also recorded. The analyzed sample was considered homogeneous despite of the type of surgery and postoperative time duration. It was evidenced high values of responsiveness coefficient (coefficient = 3.22), Cronbach alpha (internal consistency) (Cronbach α= 0.8 during both eye cleaning and tracheal suctioning) and Intraclass Correlation Coefficient (interrater reliability) (ICC= 0.8 during eye cleaning; ICC= 0.9 during tracheal suctioning). As to the validity, changes on BPS score in three assessment moments resulted in significant difference between rest and painful procedure, with the highest score values in this last one (p≤ 0.0001). However, correlations between pain and other variables (hemodynamic parameters, sedation level, and severity of disease) were not significant. Based on these results, the Brazilian BPS version was considered a valid instrument for ICUs in Brazil. / A mensuração da dor em Unidade de Terapia Intensiva é um tema que obteve maior notoriedade nos últimos anos devido à necessidade de desenvolvimento de métodos farmacológicos mais eficazes e de aperfeiçoamento do manejo da dor em pacientes críticos. Esta mensuração pode ser realizada através de instrumentos validados para tal fim, como a Behavioral Pain Scale (BPS). A dificuldade de comunicação de pacientes em uso de via aérea artificial, bem como a inexistência de validação da versão brasileira de uma escala que mensure dor em pacientes adultos mecanicamente ventilados justifica a relevância deste estudo que objetivou validar a versão brasileira da BPS além de correlacionar os escores desta escala com os registros das variáveis fisiológicas, nível de sedação e estado geral de saúde da amostra estudada. Trata-se de um estudo observacional transversal realizado no período compreendido entre os meses de fevereiro e agosto de 2014. A amostra foi composta por 25 pacientes adultos em uso de ventilação mecânica invasiva (VMI), sedados e/ou inconscientes, internados na Unidade de Terapia Intensiva Cardiológica (UTI-Cardio) do Hospital de Cirurgia em Aracaju-Sergipe-Brasil. A avaliação dos pacientes por meio da BPS e a observação da pressão arterial, frequência cardíaca e saturação periférica de oxigênio por dois avaliadores simultaneamente foi realizada em três momentos: repouso, durante limpeza do olho (estímulo não doloroso) e durante aspiração traqueal (estímulo doloroso). Outras variáveis como nível de sedação e estado geral de saúde foram respectivamente avaliadas através da Escala de Ramsay, Richmond Agitation Sedation Scale (RASS) e o escore APACHE II (Acute Physiology Health Chronic Evaluation). Também foi registrado o uso de fármacos sedativos e analgésicos administrados durante a avaliação do paciente. A amostra avaliada foi considerada homogênea no que concerne ao tipo de cirurgia e tempo de pós-operatório. Foram evidenciados valores elevados do coeficiente de responsividade (coeficiente = 3,22), Cronbach alfa (consistência interna) (Cronbach α= 0,8 durante repouso e limpeza do olho) e do coeficiente de correlação intraclasse (confiabilidade interavaliador) (CCI =0,8 durante limpeza do olho; CCI= 0,9 durante aspiração traqueal). Quanto à validade, a mudança na pontuação da BPS nos três momentos de avaliação resultou na diferença significativa entre o repouso e procedimento doloroso, sendo encontrados neste último os maiores escores de dor (p≤ 0,0001). Contudo, as correlações entre dor e as demais variáveis (parâmetros hemodinâmicos, nível de sedação e severidade da doença) não foram significativas. A partir destes resultados, a versão brasileira da Behavioral Pain Scale foi considerada um instrumento válido para utilização em UTIs do Brasil.

O trabalho avaliou o uso de slogans e iconografia computacional 3D para fins educacionais. Foram aplicadas 3 formas textuais (tópicos longos; slogans e junção das formas anteriores), para avaliar o aprendizado de estudantes de 3º ano médico sobre Doenças Sexualmente Transmissíveis. Aplicou-se 10 questões de múltipla escolha imediatamente após a leitura e 60 dias após a primeira aplicação. Houve aumento de memorização nos estudantes que utilizaram o texto contendo a junção das formas. Após, demonstrou-se que as iconografias podem condensar grandes quantidades de informações e transmiti-las em pouco tempo, utilizando para análise o Ciclo do Pelo. Foram então inseridos slogans nas iconografias, apresentando uma nova forma de transmissão rápida da informação. Essas ferramentas, podem trazer benefícios ao aprendizado do aluno. / The paper evaluated the use of slogans and computational 3-D iconography for educational purposes. Three textual forms were applied (long topics; slogans; combination of the two previous forms), in order to evaluate the learning of third-year medical students about Sexually Transmitted Diseases. Ten multiple-choice questions were applied immediately after reading and 60 days after the first application. There was an increase in memorization in students who used the text with combination of the didactic material forms. Before, we demonstrated that the iconographies can condense high quantities of information and transmit them in a short time, utilizing the theme Hair Cycle for analysis. Slogans were inserted in the iconographies, presenting a new form of rapid transmission of information. These tools, when utilized in educational material, may provide benefits to the learning.

Assessment of the foreign direct investment (FDI) spillovers in the People's Republic of China (PRC) has become a lively area of research in the past decades; nonetheless, the existing primary literature seems to be inconclusive. The present thesis revises the literature through a meta-analytical approach using Bayesian Model Averaging (BMA). Considering that the previous liter- ature reviews are of either inferior quality or incomparable focus, our research is based on a collection of 1081 estimates from 14 primary studies published between 2007 and 2017 comprising data from 1995 to 2012. A variety of 85 characteristics of the observations is coded whilst we employ at least 30 of these within each BMA estimation. Through separate testing of individual spillover measures (horizontal, forward, and backward), an extensive evidence of publication bias is collected for horizontal spillovers in PRC-exaggerating the mean magnitude of the reported estimates. Finally, the thesis identifies that the spillover effect from FDI inflows originating from the area of Hong Kong, Macau, and Taiwan is systematically different from the others.

Au cours du XXème siècle jusqu’à aujourd’hui, des artistes d’horizons divers ont revendiqué comme oeuvres des gestes banals, effectués dans l’espace public. Réalisées au sein de la foule des grandes villes, aucune de ces actions n’a pourtant eu lieu en présence d’un spectateur. En raison de leur indiscernabilité artistique lors de leur effectuation, nous les nommons des « actions furtives ». Considérant que l’adjectif furtif qualifie ce qui cherche « à échapper au regard, à passer inaperçu », comment ces actions deviennent-elles oeuvres ? Notre travail s’attache à étudier ce paradoxe à travers notamment l’oeuvre de Vito Acconci, Adrian Piper, Jiří Kovanda ou Francis Alÿs. Nous cherchons à saisir l’élan qui a mené ces artistes à quitter les lieux traditionnellement consacrés à l’art pour embrasser la foule des grandes villes et faisons l’hypothèse d’une « attitude de la modernité » ; l’artiste s’engage activement dans le monde et son élaboration. Nous étudions ensuite la façon dont l’action furtive devient oeuvre et la structure qui se dessine, entre dissimulation et révélation. Les publications permettent à l’action furtive de faire oeuvre et fonctionnent comme des « écrans » qui désignent l’acte passé et le cachent à la fois, orientant la perception du spectateur à rebours. Enfin nous analysons la réception de l’action furtive devenue oeuvre, dont le délai instaure une relation dialogique et contribue à transformer le public. L’oeuvre affirme ainsi sa valeur d’exemplarité et invite le spectateur à agir. / Throughout the XXth century and still today, artists of diverse horizons have claimed for ordinary acts done out in public spaces the status of artworks. Created amidst big city crowd, none of these acts, however, took place in the presence of a spectator. Due to artistic indiscernibility during their effectuation, we name them “furtive actions”. Considering the adjective “furtive” to qualify which seeks to “to escape the look, to go unnoticed”, how might such actions become artworks? Our task is to study this paradox, notably through the works of Vito Acconci, Adrian Piper, Jiří Kovanda or Francis Alÿs.We aim to apprehend the energy that led these artists to leave the sites traditionally dedicated to art in order to embrace the metropolitan crowds. We propose as hypothesis an “attitude of the modern”; the artist engages actively within the world and its elaboration. We then study the way furtive action becomes art work and the structure that takes shape, between dissimulation and revelation. These publications enable the furtive action to become art and to function as “screens” that indicate the past act and at the same time conceal it, orienting in reverse the perception by the spectator. Finally, we analyze reception of the furtive action become art work, wherein the time-lapse sets up a dialogic relationship and contributes to a transformation of the public. The art work thus asserts its value of exemplarity and invites the spectator toward action.

Deflecting a significant portion of corn production to ethanol for fuelling purposes increases the prices of corn. Although many studies examined the relationship between biofuels and agricultural commodity prices in the last decade, their estimates vary broadly (from nil to 85%). Without knowing the precise estimates of these impacts, policymakers can hardly set the biofuel policies optimally. I conduct a meta-analysis of over 150 estimates of the effect of corn ethanol production on corn prices to bring more clarity to the issue. Furthermore, I detect substantial selective reporting bias in the literature. After controlling for this bias with the use of various methods including the mixedeffects multilevel model, the results show that the true effect of a one billion gallon expansion in corn ethanol on corn prices is about 2-3%, which is less than commonly thought.

Afrikaans: Die Vlootkommissaris, Jahleel Brenton, se ywer en passie vir Bybelverspreiding lei tot die stigting van die tweede Hulpvereniging van die Britse en Buitelandse Bybelgenootskap in Afrika. Hierdie stigtingsvergadering vind plaas onder voorsitterskap van die luitenant-goewemeur aan die Kaap, sir Rufane Donkin, op 23 Augustus 1820. Dit is eers in 1965, dat die Bybelgenootskap van Suid-Afrika 'n selfstandige Bybelgenootskap word en sy plek kan inneem by die Wereldbond van Bybelgenootskappe as 'n finansieel bydraende Genootskap tot die Werelddiensprogram. In 1970 verskyn die publikasie, God het laat groei, wat die geskiedenis van die Bybelgenootskap van Suid-Afrika beskryf vanaf 1820 tot 1970. Sedert hierdie publikasie verskyn het, is daar nog nie weer so 'n uitgebreide studie uitgevoer nie. Jaarverslae is elke jaar gepubliseer, maar dit was gerig op die donateurskorps, met inligting wat by wyse van opsommings weergegee is. Dit is egter opmerklik dat daar nog nooit 'n missiologiese studie gedoen is oor die werksaarnhede van die Bybelgenootskap van Suid-Afrika nie. As gevolg van die feit dat die Bybelgenootskap die enigste organisasie in Suid-Afrika is wat die Bybel amptelik vertaal, produseer en versprei in al die inheemse tale van ons land, moet daar gevra word na die relevansie van hierdie organisasie se werksaarnhede vir die sendingontwikkeling in Suid-Afrika asook Suider-Afrika. <op> Betrokkenheid deur die Bybelgenootskap by vertalingsprojekte in die inheemse tale van ons land, het deur die jare baie gewissel. Tans word vertaalspanne in diens van die Bybelgenootskap van Suid-Afrika gestel en hulle doen die vertaalwerk namens die kerk, sendingorganisasies en breë Christelike gemeenskap. Die Bybelgenootskap van Suid-Afrika staan in 'n baie unieke verhouding met die kerk, sendingorganisasies en die breë Christelike gemeenskap. Samewerking geskied op 'n wye spektrum van terreine. Die Bybelgenootskap is afhanklik van die kerke, sendingorganisasies en die breë Christelike gemeenskap, vir menslike hulpbronne en finansiële ondersteuning. Die kerke, sendingorganisasies en die breë Christelike gemeenskap is weer van die Bybelgenootskap afhanklik vir Bybels in die inheemse tale van ons land, asook ander verwante materiaal. Hierdie studie het aangetoon dat daar 'n missionere visie aanweslg is in die werksaamhede van die Bybelgenootskap van Suid-Afrika, maar ook by die donateurskorps. Hierdie missionêre visie het inderdaad daartoe gelei dat die Christendom in Suid-Afrika gevestig kon word. Hierdie studie toon baie duidelik aan dat die Bybelgenootskap van Suid-Afrika 'n integrale deel van die missionêre speelveld in Suid¬Afrika is, ook ten opsigte van die toekoms. English: The Naval Commissioner, Jaheel Brenton's passion and diligence regarding Bible distribution leads to the founding of the second Auxiliary of the British and Foreign Bible Society in Africa. This founding meeting takes place on 23 August 1820 under the chairmanship of the lieutenant-governor at the Cape, Sir Rufane Donkin. Only in 1965 does the Bible Society of South Africa become an independent Bible Society and became immediately a contributing Society towards the World Service Programme of the United Bible Societies. In 1970 the publication, God made it grow, appears, describing the history of the Bible Society of South Africa from 1820 to 1970. A comprehensive study of this has not hitherto been executed. Reports are published annually but are directed at the contributing donors of the Bible Society of South Africa with relevant information conveyed in the form of summaries. It is, however, remarkable that a missiological study has never been done on the activities of the Bible Society of South Africa. Considering the fact that the Bibles Society is the only organization in South Africa which officially translates, produces and distributes the Bible in all our indigenous languages, one must question the relevance of this organization's activities towards the development of missionary actions in South Africa and Southern Africa. Over the years the Bible Society's involvement regarding translation projects into the indigenous languages of our country has changed considerably. Nowadays, teams of translators are appointed in the service of the Bible Society. They do the translation on behalf of the Church, missionary organizations and the broader Christian community. The Bible Society of South Africa maintains a unique relationship with the Church, missionary organizations and with the broader Christian community and a wide spectrum of co-operation exists. The Bible Society is dependant on the churches, missionary organizations and the broader Christian community for human resources and financial support. Accordingly, churches, missionary organizations and the broader Christian community are dependant on the Bible Society for Bibles and other related material in the indigenous languages of our country. This study has indicated the presence of a missionary vision in the activities of the Bible Society of South Africa as well as their donors. Indeed this missionary vision has resulted in the establishment of Christianity in South Africa. This study clearly indicates that the Bible Society of South Africa is an integral part of the missionary playing-field in South Africa, also with regard to the future. / Thesis (PhD (Science of Religion and Missiology))--University of Pretoria, 2007. / Science of Religion and Missiology / unrestricted

Esta dissertação traz múltiplos estudos que se destinam a investigar os fatores internos e externos que influenciam a publicação dos pesquisadores brasileiros na área da Administração. Para tanto, quatro etapas são traçadas, que consistem em quatro estudos distintos e interligados. Eu exploro a publicação de artigos, as competências essenciais para a publicação de artigos de alto nível, fatores de rejeição e as diferenças entre rankings de periódicos. Esta dissertação tem implicações para três públicos principais. Primeiro, para os pesquisadores que são capazes de entender melhor os fatores que influenciam sua produtividade. Em segundo lugar, os programas de doutorado são capazes de saber quais são os fatores mais importantes na formação de futuros pesquisadores. Em terceiro lugar, as agências institucionais podem repensar demandas institucionais de publicação e suas verdadeiras implicações. / Scholars need to conduct research and publish their studies to cope with institutional rules and advance in their career, which makes publishing a subject of great importance for all the academy. In this dissertation I conduct multiple studies that investigate a set of internal and external factors that influence research publication of Brazilian researchers in the field of Management. For this, four steps are used, consisting in four distinct and interconnected studies. Therefore, I explore the publication of articles, core competencies for top-level publication, rejection factors, differences between journal ranks. The studies contained in this dissertation have implications to three main audiences. First, scholars are able to better understand what influences their productivity. Second, doctoral programs are able to know what are the most important factors in the training of future researchers. Third, institutional agencies can rethink institutional demands for publication and their true implications.
