Modelagem e avaliação de um sistema modular para gerenciamento de informação na Web

O gerenciamento de informação pode ser identificado como desafio crucial, sobretudo no tocante aos conteúdos de websites e sistemas de informação em ambiente web. Assim, o desenvolvimento de meios e métodos para gerenciamento de conteúdos é tema deste artigo, o qual objetiva, através de um relato de aplicação de pesquisa participativa, apresentar a descrição funcional de um sistema modular para gerenciamento de conteúdos em ambiente web. São discutidos aspectos relacionados com o desenvolvimento do sistema e sua aplicação em 28 websites. Adicionalmente, é apresentada uma avaliação quantitativa com base na satisfação, facilidade de uso percebida, freqüência de uso e importância dos módulos que o compõem. Entre os principais resultados, aponta-se a evidência da flexibilidade da proposta modular e a constatação de que os gestores se mostraram satisfeitos com o sistema, não apresentando dificuldade de uso e obtendo resultados positivos com o uso da ferramenta.

Os museus portugueses e a Web 2.0

O presente artigo dá a conhecer um projecto de investigação que teve como objectivo determinar e analisar a partir da observação dos sítios Web dos museus portugueses quais as ferramentas Web 2.0 usadas por estas instituições no desenvolvimento das suas actividades. Neste sentido, foram seleccionados como amostra os 125 museus pertencentes à Rede Portuguesa de Museus. Os resultados obtidos permitem-nos afirmar que utilização das ferramentas Web 2.0 por parte dos museus portugueses analisados está numa fase inicial. A ferramenta mais usada é o blogue. Foram, também, identificados projectos pioneiros ao nível dos wikis, Licenças Creative Commons, Youtube, Flickr e redes sociais on-line.

Web decoration of Micrathena sexpinosa (Araneae: Araneidae): a frame-web-choice experiment with stingless bees

The function of silk web decorations in orb weaving spiders has been debated for decades. The most accepted hypothesized functions are that web decorations I) provide camouflage against predators, 2) are an advertisement for vertebrates to avoid web damage, or 3) increase the attraction of prey to the web. Most studies have focused on only a few genera, Argiope being the most common. In this study, I evaluated the prey attraction hypothesis of silk decorations for a species of a poorly studied genus in this topic, Micrathena sexpinosa Hahn 1822. I used a web-choice experiment in which I presented empty or web-bearing frames at the end of a tunnel to stingless bees (Tetragonisca angustula). This frame-choice experiment consisted of the following comparisons: decorated web vs. empty frame, decorated web vs. undecorated web, and undecorated web vs. empty frame. Webs with decoration intercepted significantly more bees than empty frames and undecorated webs. Therefore, the decorations of Micrathena sexpinosa might play a role in increasing foraging success.

Multiplan Spreadsheets for Highway and Hydraulic Engineering Computations in County Engineering Offices, HR-284, 1987

Multiplan spreadsheet solutions were developed for a set of hydraulic and highway engineering computations of common interest to county engineers. These include earthwork, vertical and horizontal curves, staking superelevated curves and sign inventories for highways. The hydraulic applications were ditch flow, runoff, culvert size and stage discharge.

Dépistage et intervention brève par internet pour la consommation d'alcool a risque: www.alcooquizz.ch [Web-based screening and brief intervention for unhealthy alcohol use: www.alcooquizz.ch].

Many individuals with unhealthy alcohol use have few or no contact with the health care system and are therefore unlikely to receive information or a brief intervention from a health care professional. Consequently, many Internet-based interventions have been developed. These interventions can reach a large population. We present in this report www.alcooquizz.ch, a website providing tailored feedback and information on alcohol use and its consequences. In six months and a half, more than 15000 individuals visited the website. It appropriately targets individuals with unhealthy alcohol use and users' satisfaction was high. Internet is a valuable option to provide health related information and secondary prevention interventions for unhealthy alcohol use.

Swiss EMBnet node web server.

EMBnet is a consortium of collaborating bioinformatics groups located mainly within Europe (http://www.embnet.org). Each member country is represented by a 'node', a group responsible for the maintenance of local services for their users (e.g. education, training, software, database distribution, technical support, helpdesk). Among these services a web portal with links and access to locally developed and maintained software is essential and different for each node. Our web portal targets biomedical scientists in Switzerland and elsewhere, offering them access to a collection of important sequence analysis tools mirrored from other sites or developed locally. We describe here the Swiss EMBnet node web site (http://www.ch.embnet.org), which presents a number of original services not available anywhere else.

ABCtoolbox: a versatile toolkit for approximate Bayesian computations.

BACKGROUND: The estimation of demographic parameters from genetic data often requires the computation of likelihoods. However, the likelihood function is computationally intractable for many realistic evolutionary models, and the use of Bayesian inference has therefore been limited to very simple models. The situation changed recently with the advent of Approximate Bayesian Computation (ABC) algorithms allowing one to obtain parameter posterior distributions based on simulations not requiring likelihood computations. RESULTS: Here we present ABCtoolbox, a series of open source programs to perform Approximate Bayesian Computations (ABC). It implements various ABC algorithms including rejection sampling, MCMC without likelihood, a Particle-based sampler and ABC-GLM. ABCtoolbox is bundled with, but not limited to, a program that allows parameter inference in a population genetics context and the simultaneous use of different types of markers with different ploidy levels. In addition, ABCtoolbox can also interact with most simulation and summary statistics computation programs. The usability of the ABCtoolbox is demonstrated by inferring the evolutionary history of two evolutionary lineages of Microtus arvalis. Using nuclear microsatellites and mitochondrial sequence data in the same estimation procedure enabled us to infer sex-specific population sizes and migration rates and to find that males show smaller population sizes but much higher levels of migration than females. CONCLUSION: ABCtoolbox allows a user to perform all the necessary steps of a full ABC analysis, from parameter sampling from prior distributions, data simulations, computation of summary statistics, estimation of posterior distributions, model choice, validation of the estimation procedure, and visualization of the results.

Portal web para la empresa Ruben's instalaciones y excavaciones

Este proyecto consiste en el desarrollo de un portal web para una empresa de construcción. Estará formado por una parte pública de cara al cliente que contiene diversa información de la empresa y una sección para contactar con la empresa. Además, tendrá una parte privada de gestión de ciertos aspectos de la empresa como presupuestos y pagos, además de un módulo de estadísticas para el seguimiento. El desarrollo se ha considerado necesario debido al contexto actual y a las carencias detectadas en la empresa.
