Gestão de correio eletrónico em ambiente organizacional : uma perspetiva arquivística

O presente estudo tem como objetivo compreender a valoração de uma mensagem de correio eletrónico em ambiente corporativo, e respetiva integração no arquivo empresarial. Objetivamos, nos primeiros capítulos, descrever o modelo metodológico aplicado. Seguidamente, apresentamos uma revisão bibliográfica assente em literatura inerente à temática dos circuitos informacionais na empresa, e documentação eletrónica resultante dos mesmos, com ênfase nas mensagens de correio eletrónico. A investigação empírica teve por base a aplicação de um inquérito por questionário, tendo por amostra um grupo profissional pré-selecionado, com acesso regular a um sistema de correio eletrónico. Os resultados obtidos através da análise do material empírico permitem-nos observar uma utilização preferencial do correio eletrónico face a outros suportes comunicacionais, constituindo-se as mensagens eletrónicas no documento produzido em maior escala, em ambiente profissional. Foram igualmente verificados casos de ausência de regulamentação para criação, gestão ou arquivo de mensagens, ou mesmo de um sistema de gestão documental que permita integração das mesmas. Com base na análise empírica, e em associação com a revisão bibliográfica explanada, concluímos que estas, e outras questões enunciadas ao longo do estudo, poderão constituir-se num sério obstáculo à gestão, preservação, recuperação e integridade da informação registada por meio de mensagens de correio eletrónico, caso não sejam criados e aplicados procedimentos e sistemas de gestão orientados para a documentação eletrónica, de forma a garantir o acesso a informação de fulcral importância para empresa, enquanto evidência e memória dos processos e atividades organizacionais.

Should my company use Bitcoin?

This work project analyses the possibility for a company to trade their goods and services for bitcoins, by joining the Bitcoin network. It analyses the technological and business requirements to join the Bitcoin Network by looking at Bitcoin’s potential to act as a mean of exchange for trade, unit of account and store of value. The analysis points to the motives, benefits and risks for investors to use the Bitcoin as a traditional currency and recommends on strategies for addressing those risks and maximizing benefits. Other than companies this report, to a lesser extent, will also analyse the Bitcoin from an investor’s point of view, this is, should an investor buy bitcoins for trade and make savings on a regular and everyday basis? A major finding in this work project is that companies could start using the Bitcoin system as a legit form of payment since the benefits of using this technology outweigh the costs and risks, given the right approach. This form of payment will contribute for the upgrade of a company’s business’ image, attract a new pool of consumers and businesses that already trade in bitcoins and pressure existing financial institutions and electronic payment vendors to upgrade their service levels.

An evaluation of parchments' degradation a hybrid approach

Parchment stands for a multifaceted material made from animal skin, which has been used for centuries as a writing support or as bookbinding. Due to the historic value of objects made of parchment, understanding their degradation and their condition is of utmost importance to archives, libraries and museums, i.e., the assessment of parchment degradation is mandatory, although it is hard to do with traditional methodologies and tools for problem solving. Hence, in this work we will focus on the development of a hybrid decision support system, in terms of its knowledge representation and reasoning procedures, under a formal framework based on Logic Programming, complemented with an approach to computing centered on Artificial Neural Networks, to evaluate Parchment Degradation and the respective Degree-of-Confidence that one has on such a happening.

Optimisation of a surface mount technology process using a SnAgCu lead-free alloy

The impending introduction of lead-free solder in the manufacture of electrical and electronic products has presented the electronics industry with many challenges. European manufacturers must transfer from a tin-lead process to a lead-free process by July 2006 as a result of the publication of two directives from the European Parliament. Tin-lead solders have been used for mechanical and electrical connections on printed circuit boards for over fifty years and considerable process knowledge has been accumulated. Extensive literature reviews were conducted on the topic and as a result it was found there are many implications to be considered with the introduction of lead-free solder. One particular question that requires answering is; can lead-free solder be used in existing manufacturing processes? The purpose of this research is to conduct a comparative study of a tin-lead solder and a lead-free solder in two key surface mount technology (SMT) processes. The two SMT processes in question were the stencil printing process and the reflow soldering process. Unreplicated fractional factorial experimental designs were used to carry out the studies. The quality of paste deposition in terms of height and volume were the characteristics of interest in the stencil printing process. The quality of solder joints produced in the reflow soldering experiment was assessed using x-ray and cross sectional analysis. This provided qualitative data that was then uniquely scored and weighted using a method developed during the research. Nested experimental design techniques were then used to analyse the resulting quantitative data. Predictive models were developed that allowed for the optimisation of both processes. Results from both experiments show that solder joints of comparable quality to those produced using tin-lead solder can be produced using lead-free solder in current SMT processes.

Redes sociais de saúde como grupos de suporte online na vida de pacientes com doenças cardiovasculares

Existe um aumento no conjunto de pacientes que utilizam a internet em busca de informações que possam melhorar suas condições de saúde. Nele, distinguem-se pacientes que procuram ambientes virtuais para expor experiências, dúvidas, opiniões, emoções e inclusive criar relacionamentos visando dar ou receber apoio. Nesse sentido, há uma crescente necessidade de estudar como estes ambientes podem repercutir na saúde dos pacientes. Este artigo tem por objetivo identificar na literatura científica estudos sobre a proliferação e impacto das comunidades virtuais conhecidas como Redes Sociais de Saúde ou Grupos de Suporte Online, voltados para doenças cardiovasculares, que podem ser úteis aos pacientes com determinadas doenças, permitindo-lhes obter informação e apoio emocional. Para o levantamento bibliográfico, foi realizada revisão sistemática da literatura com artigos publicados entre 2007-2012, nas bases de dados PubMed, Association for Computing Machinery e Institute of Electrical and Electronic Engineer, que se encontram relacionados com o tema proposto, e foram selecionados quatro artigos, segundo os critérios de inclusão dos métodos. Os resultados encontrados revelam dados interessantes, relevantes segundo o aspecto de saúde, os quais podem trazer alguns benefícios terapêuticos, destacando: provisão de suporte emocional, maior adesão ao tratamento, compartilhamento de informação sobre as doenças e obtenção de experiências de vida.

Characteristics of HIV patients referred to a medication adherence program in Switzerland.

Background Since August 2004, HIV patients who encounter -or are at risk of -problems with their antiretroviral treatment (ART) are referred by their physician to a medication adherence program at the community pharmacy of the Department of Ambulatory Care and Community Medicine in Lausanne (Switzerland). The program combines motivational interviewing and electronic drug monitoring. Objective To compare the demographic and clinical characteristics as well as ART of HIV patients referred to the adherence program versus those of the entire HIV population followed in the same infection disease department in the same time frame. Method Retrospective descriptive cross-sectional study. Study time frame was defined according to the period with the highest number of HIV patients visiting the adherence program. Results Subjects included in the adherence program had more often a protease inhibitor-based regimen (64 %; 95 % CI [52-75 %] vs. 37 %) and lower CD4 cell counts (419 (252.0, 521.0); 95 % CI [305-472] vs. 500 (351.0, 720.0)) than the entire HIV population. A majority of women were included in the adherence program (66 %; 95 % CI [54-76 %] vs. 39% in the entire HIV population). Conclusion Subjects referred to the adherence program were different from the entire HIV population and showed worse clinical outcomes and were more often under salvage therapy. More women than men were included. Reasons for such a difference need to be further explored.

Configuración de la entrada/salida paralela para el cómputo de altas prestaciones

La E/S Paralela es un área de investigación que tiene una creciente importancia en el cómputo de Altas Prestaciones. Si bien durante años ha sido el cuello de botella de los computadores paralelos en la actualidad, debido al gran aumento del poder de cómputo, el problema de la E/S se ha incrementado y la comunidad del Cómputo de Altas Prestaciones considera que se debe trabajar en mejorar el sistema de E/S de los computadores paralelos, para lograr cubrir las exigencias de las aplicaciones científicas que usan HPC. La Configuración de la Entrada/Salida (E/S) Paralela tiene una gran influencia en las prestaciones y disponibilidad, por ello es importante “Analizar configuraciones de E/S paralela para identificar los factores claves que influyen en las prestaciones y disponibilidad de la E/S de Aplicaciones Científicas que se ejecutan en un clúster”. Para realizar el análisis de las configuraciones de E/S se propone una metodología que permite identificar los factores de E/S y evaluar su influencia para diferentes configuraciones de E/S formada por tres fases: Caracterización, Configuración y Evaluación. La metodología permite analizar el computador paralelo a nivel de Aplicación Científica, librerías de E/S y de arquitectura de E/S, pero desde el punto de vista de la E/S. Los experimentos realizados para diferentes configuraciones de E/S y los resultados obtenidos indican la complejidad del análisis de los factores de E/S y los diferentes grados de influencia en las prestaciones del sistema de E/S. Finalmente se explican los trabajos futuros, el diseño de un modelo que de soporte al proceso de Configuración del sistema de E/S paralela para aplicaciones científicas. Por otro lado, para identificar y evaluar los factores de E/S asociados con la disponibilidad a nivel de datos, se pretende utilizar la Arquitectura Tolerante a Fallos RADIC.

Tractament psicològic del dolor crònic en nens i adolescents

L'objectiu d'aquest projecte és que els nens i adolescents amb dolor crònic puguin gaudir d'una millor qualitat de vida. El projecte té dues línies de recerca complementàries. El primer objectiu específic és crear i adaptar instruments per avaluar l’experiència dolorosa a la població infantil. Dues són les mesures que s'han estudiat en escolars: l'escala numèrica verbal (vNRS-11) tant en paper com en format electrònic, i una versió modificada de la versió pediàtrica del Survey of Pain Attitudes (Peds-SOPA). El segon objectiu específic és avaluar els efectes de la teràpia cognitiva (TC) en una mostra de nens de 12 a 18 anys que pateixen dolor crònic. En concret, volem estudiar si algunes característiques personals i familiars dels joves (per exemple, creences relacionades amb la salut, intensitat del dolor, estratègies d'afrontament, expectatives del tractament) estan associades a l'adherència a les recomanacions terapèutiques i, en conseqüència, són variables que afavoreixen la recuperació d’aquests pacients. Un tractament de 10 sessions es porta a terme per aconseguir aquest objectiu. S’ofereix als pacients un conjunt d'habilitats i estratègies específiques per a què puguin exercir un major control dels seus símptomes i reduir l'impacte d'aquests en les seves vides. Els resultats d'aquests estudis seran de gran interès per millorar el maneig del dolor infantil. A més, els resultats determinaran quines són les variables associades amb l’adherència a les prescripcions terapèutiques. Aquest és un tema particularment d’interès pel fet de que un factor determinant de l’èxit clínic és el grau en què una persona s'adhereix a les recomanacions. D'altra banda, el desenvolupament de les mesures de dolor pediàtric és de gran rellevància tant per a clínics com per a investigadors, ja que moltes de les decisions clíniques es basen en allò que el pacient ha informat sobre el seu dolor.

From Naples 1963 to Rome 2013 - A brief review of how the International Research Group on Ostracoda (IRGO) developed as a social communication system

The 1st International Symposium on Ostracoda (ISO) was held in Naples (1963). The philosophy behind this symposium and the logical outcome of what is now known as the International Research Group on Ostracoda (IRGO) is here reviewed, namely ostracodology over the last 50 years is sociologically analysed. Three different and important historic moments for the scientific achievements of this domain are recognised. The first one, between about 1963-1983, is related to applied research for the oil industry as well as to the great interest in the better description of the marine environment by both zoologists and palaeontologists. Another important aspect during this period was the work by researchers dealing with Palaeozoic ostracods, who had their own discussion group, IRGPO. Gradually, the merger of this latter group with those dealing with post-Palaeozoic ostracods at various meetings improved communication between the two groups of specialists. A second period was approximately delineated between 1983 and 2003. During this time-slice, more emphasis was addressed to environmental research with topics such as the study of global events and long-term climate change. Ostracodologists profited also from the research "politics" within national and international programmes. Large international research teams emerged using new research methods. During the third period (2003-2013), communication and collaborative research reached a global dimension. Amongst the topics of research we cite the reconstruction of palaeoclimate using transfer functions, the building of large datasets of ostracod distributions for regional and intercontinental studies, and the implementation of actions that should lead to taxonomic harmonisation. Projects within which molecular biological techniques are routinely used, combined with sophisticated morphological information, expanded now in their importance. The documentation of the ostracod description improved through new techniques to visualise morphological details, which stimulated also communication between ostracodologists. Efforts of making available ostracod information through newsletters and electronic media are evoked.
