Invasive candidiasis: comparison of management choices by infectious disease and critical care specialists.

OBJECTIVE: To compare the management of invasive candidiasis between infectious disease and critical care specialists. DESIGN AND SETTING: Clinical case scenarios of invasive candidiasis were presented during interactive sessions at national specialty meetings. Participants responded to questions using an anonymous electronic voting system. PATIENTS AND PARTICIPANTS: Sixty-five infectious disease and 51 critical care physicians in Switzerland. RESULTS: Critical care specialists were more likely to ask advice from a colleague with expertise in the field of fungal infections to treat Candida glabrata (19.5% vs. 3.5%) and C. krusei (36.4% vs. 3.3%) candidemia. Most participants reported that they would change or remove a central venous catheter in the presence of candidemia, but 77.1% of critical care specialists would start concomitant antifungal treatment, compared to only 50% of infectious disease specialists. Similarly, more critical care specialists would start antifungal prophylaxis when Candida spp. are isolated from the peritoneal fluid at time of surgery for peritonitis resulting from bowel perforation (22.2% vs. 7.2%). The two groups equally considered Candida spp. as pathogens in tertiary peritonitis, but critical care specialists would more frequently use amphotericin B than fluconazole, caspofungin, or voriconazole. In mechanically ventilated patients the isolation of 10(4) Candida spp. from a bronchoalveolar lavage was considered a colonizing organism by 94.9% of infectious disease, compared to 46.8% of critical care specialists, with a marked difference in the use of antifungal agents (5.1% vs. 51%). CONCLUSIONS: These data highlight differences between management approaches for candidiasis in two groups of specialists, particularly in the reported use of antifungals.

Esquemes de xifrat homomòrfics per a votació electrònica

This bachelor's degree thesis deals with homomorphic public-key cryptography, or in other words cryptosystems with special addition properties. Such cryptosystems are widely used in real life situations, for instance to make electronic voting secure. In Chapter 1 a few basic algebra results and other key concepts are introduced. Chapters 2 and 3 contain the algorithms and properties of the two cryptosystems which are considered to be the best for e-voting: Paillier and Joye-Libert. The thesis is concluded in Chapter 4, by comparing running times of the two above-mentioned cryptosystems, in simulations of real-life e-voting systems, with up to tens of thousands of voters, and different levels of security. Through these simulations, we discern the situations where each of the two cryptosystems is preferable.

Ocho dudas razonables sobre la necesidad del voto electrónico

En un momento en que se generaliza el uso de las diferentes soluciones de voto electrónico, parece razonable hacer balance sobre cuáles son los principales obstáculos que esta «última revolución electoral» debe superar. Antes, sin embargo, consideramos necesario discutir los principales malentendidos que se han creado en torno al voto electrónico, así como intentar aclarar cuáles son los motivos que se aducen para su implementación. A partir de aquí, se presentan ocho grandes dudas a las que todavía no se ha dado una respuesta satisfactoria en su conjunto, si bien una buena parte de estos aspectos han sido objeto de especial atención en algunas experiencias de voto electrónico.

Oportunidades estratégicas para la implementación del voto electrónico remoto

A partir d"una anàlisi comparada de diferents experiències d"implementació del vot electrònic remot a Espanya i de dades sociopolítiques de valoració d"aquestes votacions, es discuteixen els diferents arguments justificadors de la seva implementació. S"analitzen així els arguments estructurals que incentiven l"adopció del vot electrònic en el context del funcionament dels sistemes polítics democràtics, sense oblidar, però, la percepció i l"avaluació dels ciutadans davant l"ús de les NTIC per a l"emissió del vot. L"anàlisi se centra en la presa en consideració de les debilitats i les amenaces potencials associades a la introducció del vot electrònic, per a concloure que la seva implementació haurà d"ésser progressiva i complementària als sistemes tradicionals de votació.

Análisis de los alcances y limitaciones de la implementación del voto electrónico en América Latina, lecciones para Colombia

La tecnología electoral que da paso a la incorporación del voto electrónico no es simplemente un medio, sino implica cierto conocimiento y un cambio en la cultura electoral de los ciudadanos. Puesto que, la tecnología no podrá ser comprendida e implementada de manera correcta y exitosa mientras sea pensada solo como un medio pues supone necesariamente un conocimiento de las causas y razones que entrelazan los procesos del voto electrónico en su conjunto. Así, la tecnología electoral implica reglas y prácticas cotidianas que permitan la familiarización para con la tecnología del electorado. De ahí que se observe mucho más allá de las tendencias globales los rasgos específicos de cada país como su historia particular, los procesos por los que ha pasado, su situación política, la confianza que tienen los ciudadanos en las instituciones políticas y en los organismos electorales, entre otros que permiten proponer estrategias que posibiliten la implementación del voto electrónico o su mejoramiento para los países que ya lo han implantado.

A Design Methodology for Computer Security Testing

The field of "computer security" is often considered something in between Art and Science. This is partly due to the lack of widely agreed and standardized methodologies to evaluate the degree of the security of a system. This dissertation intends to contribute to this area by investigating the most common security testing strategies applied nowadays and by proposing an enhanced methodology that may be effectively applied to different threat scenarios with the same degree of effectiveness. Security testing methodologies are the first step towards standardized security evaluation processes and understanding of how the security threats evolve over time. This dissertation analyzes some of the most used identifying differences and commonalities, useful to compare them and assess their quality. The dissertation then proposes a new enhanced methodology built by keeping the best of every analyzed methodology. The designed methodology is tested over different systems with very effective results, which is the main evidence that it could really be applied in practical cases. Most of the dissertation discusses and proves how the presented testing methodology could be applied to such different systems and even to evade security measures by inverting goals and scopes. Real cases are often hard to find in methodology' documents, in contrary this dissertation wants to show real and practical cases offering technical details about how to apply it. Electronic voting systems are the first field test considered, and Pvote and Scantegrity are the two tested electronic voting systems. The usability and effectiveness of the designed methodology for electronic voting systems is proved thanks to this field cases analysis. Furthermore reputation and anti virus engines have also be analyzed with similar results. The dissertation concludes by presenting some general guidelines to build a coordination-based approach of electronic voting systems to improve the security without decreasing the system modularity.

Planteamientos sobre Sistemas de Voto y Democracia Electrónica.

This paper present a preliminary analysis of electronic voting schemes and the requirements of Electronic Democracy as a part of the work carried out by the authors in the VOTESCRIPT project (TIC2000-1630-C02). A summary of the most relevant experiences on this field are discussed and a basic classification of them is pointed out, according to different degrees on process computerization. As it is shown, most of them only take into account a technological perspective, just trying to imitate the conventional voting schemes. A citizen-base bottom-up perspective is proposed to analyze the implementation of electronic voting systems in order to avoid citizen rejection. The paper also hallmarks the new technical possibilities created to be applied to the development of citizen?s right realm. Further than conventional voting schemes, the paper proposes the use of advanced security services to extend conceptualization of Electronic Democracy in which citizens have a key role on decision making processes.

INFLUÊNCIA DA COMUNICAÇÃO POLÍTICA NO SISTEMA DE VOTAÇÃO ELETRÔNICO BRASILEIRO

A velocidade da informação e do conhecimento instaurou na sociedade contemporânea uma constante busca pela melhoria dos processos informacionais, com vistas a garantir maior rapidez nos processamentos e resultados. No universo público, as exigências caminham de modo similar, sob o olhar do eleitor cidadão, portanto, a proposta da pesquisa é promover um panorama do sistema eletrônico de votação brasileiro, mais precisamente a Urna Eletrônica e transitar desde a concepção do projeto nos idos da década de 90 até o momento atual, apontando um olhar científico para as ações comunicacionais do Tribunal Superior Eleitoral (TSE), no sentido de promover campanhas publicitárias para fomentar a conscientização do sistema informatizado de voto pelos eleitores, supostamente mais rápido e eficiente. A pesquisa utiliza para fins descritivos múltiplas visões da comunicação da urna: por intermédio do órgão mantenedor, os políticos, diretamente envolvidos no pleito competitivo e os consultores políticos, atuantes nas estratégias de bastidores das campanhas eleitorais. Essa diversidade de visões e posições acerca da credibilidade do sistema busca propiciar a pesquisa um caráter de macro compreensão dos impactos de um sistema informatizado em um ambiente democrático.(AU)

Głosowanie elektroniczne – nowe wyzwanie dla demokracji?

The notion of democracy poses a significant challenge and problem in modern considerations on history, philosophy and politics. At present, in the face of the so-called information revolution, democracy has undoubtedly undergone profound and easily visible transformations. It can be said that the application of IT to exercise democratic power has brought about a revolution that will span a period of many years, given the different potential differing states have to spread the new technologies. The development of information and communications technology (ICT) has introduced new notions related to democracy, such as teledemocracy, technopolitics or electronic democracy (e-democracy). The subject of this paper, electronic voting (e-voting) is among the highly significant instruments of e-democracy. Electronic voting is the fulfillment of the principle of national sovereignty as it can be applied in the procedures of both indirect (e-elections) and direct (e-referendum) democracy.
