Impacto das tecnologias em contexto educativo formal

Publicado em "Revista galego-portuguesa de psicoloxía e educación : revista de estudios e investigación en psicología y educación, ISSN 1138-1663, Vol. Extra 1, 2007"Constitui propósito deste artigo reflectir sobre o papel dos objectos tecnológicos no processo de aprendizagem dos jovens em idade escolar. Não se questiona, hoje, o uso do computador, tanto como meio de informação e difusão, tanto como ferramenta de trabalho. Apesar de os jovens estarem saturados de objectos tecnológicos — TV, vídeo, DVD, telemóvel, consolas, entre outros —, a escola portuguesa, sobretudo ao nível do Ensino Básico, continua por um lado a ignorar alguns e, por outro, a ter dificuldade em incorporar outros no contexto de sala de aula como meio de aprendizagem que pode promover condições de “sucesso”. Com este trabalho pretendemos mostrar que ainda não se avaliaram todas as consequências da falta desta tecnologia em contexto de sala de aula. Esta reflexão parte do trabalho desenvolvido com professores, quer da formação especializada, quer pós-graduada, quer ainda da nossa actividade enquanto docentes e investigadores em Educação.CIEC - Centro de Investigação em Estudos da Criança, UM (UI 317 da FCT

Improvement of performance indicators after Scrum re-implementation in software development teams

Dissertação de mestrado em Engineering Project ManagementThe business world is more competitive than ever, and companies must adapt to a very fast passed consumer behaviour. Small and medium companies must be quick on their feet and have the ability to rapidly answer to the shifts in trends and products. In order to do so, businesses have shifted from Traditional project management to an Agile project management. Even though Agile project management has become very trendy, implementing an Agile framework requires work and an adaption period. Living Map adopted an Agile framework – Scrum – one year ago, but because they changed their Scrum Master, the process gradually broke and became problematic. This research was proposed by the company, to re-implement Scrum and analyse the changes on the performance indicators of the Software Development teams. The main goal was to collect data after each Sprint completion and compare it to old data collected previously by the researcher whilst being an intern. The first step was to re-define and re-implement Scrum within the two development teams. The researcher acted as the Scrum Master of both teams in order to be closer to them. This dissertation describes the re-implementation of Scrum, the adaptive measurements that were made during a 5-iteration cycle and the changes on the performance indicators that originated from it. In general, not only did every performance indicators had a significant growth but also, the understanding of Scrum increased, and the overall satisfaction of the Teams also improved.O mundo de negócios tem-se tornado mais competitivo do que nunca. As empresas têm de se adaptar às alterações rápidas do comportamento dos consumidores. Pequenas e médias empresas têm de ter a habilidade de responder rapidamente às mudanças das tendências e dos produtos. De forma a conseguirem fazer isto, há uma mudança da gestão de projetos tradicional para gestão de projetos ágil. Porém, implementar uma mentalidade ágil requer esforço e um período de adaptação. A empresa Living Map adotou um framework ágil - Scrum - há um ano atrás, mas por terem mudado de Scrum Master, o processo acabou por se deteriorar e tornar problemático. A pesquisa de reimplementar o Scrum em duas equipas de desenvolvimento de software foi proposta pela empresa, e o investigador desempenhou o papel de Scrum Master de ambas as equipas. O objetivo principal foi recolher dados após o fim de cada Sprint e comparar os mesmos com dados recolhidos de Sprints anteriores. O primeiro passo foi redefinir e reimplementar Scrum em duas equipas de desenvolvimento de software. Esta dissertação descreve a reimplementação de Scrum, as medidas adaptativas que foram tomadas durante um ciclo de 5 iterações e as mudanças dos indicadores de performance que ocorreram. Em geral, não só os indicadores de performance tiveram um crescimento significativo, mas o conhecimento sobre Scrum e a satisfação das equipas melhorou

Prevention of airborne disposal from staff in the O.R. reducing the risk of infection: what are the benefits of using clean air suits or scrub suits?

Experts in infection control are often asked about issues related to the use of scrubs and clean air suits in the operating room (OR). So, what are clean air suits and scrub suits? This article seeks to highlight the most relevant information of this products and try to define the benefits of using them for preventing airborne disposal from the surgical staff, reducing the risk of infection. No scientific data support the practice of using scrub suits as a means for preventing transmission of infection, but on the other side we have a vast amount of studies regarding the effectiveness of clean air suits. However this won´t invalidate the use of scrub suits, just validating that this type of studies has to be done for scrubs suits

The construction of an odour brand for children clothing

ISBN 978-2-7466-2858This research present the construction of an odour brand for a children clothing brand. Therefore, this study had the goal to verify the acceptance of an odour brand by children’s and based on this data´s, conceive an odour brand for this specific brand. The author’s analysed the children´s perception through inquiries to discover the adequate scent to apply on the children´s garment, having in consideration the concept of the brand. The results were based on inquiries realised in store environment. The survey was conducted in two phases, with two groups of children with ages between 7 and 10 years and another group from 11 to 14 years. These groups comprised children of both genders. The results of this research show that the garments and advertising material finished with the selected odours in the first part of this study has positive acceptation by the target audience. We also determine an odour brand for the studied brand and it was found that they have a specific odour that differentiates them from other clothing brands. Finally, we built a R & D procedure for the creation of an odour brand, applicable to any market segment that pretend to use a personalised odour

The Role of Educational Technology in Caregiving

Huge demographic and socio-economic changes are part of the experience of present societies. One consequence is the aging of the population and increasingly more people without the capacity for self-care. The provision of intergenerational care, namely caring for the older individuals, is a focus of attention for health professionals, but is also part of the political and social agenda. There is a need to regulate, support, and facilitate the daily life of families who have a dependent aged member. In contemporary societies, the use of information and communication technologies (ICT) is an important driver of innovation, responsible for a large transformation of living standards and new social behaviors. Within the scope of the provision of informal care, ICT can provide a great support, representing a primordial tool for updating the organizations in order to improve their efficiency, incorporating and making available services, and anticipating needs. Thus, the development of equipment, electronic applications, and websites for the elderly or their family caregivers should be conceptualized and customized to the profile of these users. A major challenge faced by healthcare institutions is to focus their services by organizing them around citizens’ needs

Optimal solution of a diffusion equation with a discrete source term

In this paper we study the numerical behavior of a diffusion equation with a discrete control source term. The equation is discretized in space by finite differences and in time by an implicit scheme. The control variables are calculated in order to minimize an objective function, taking into account some restrictions. We define two strategies to obtain the optimal solution and present some numerical results in a context of a model that describes the oxygen concentration in a single chamber microbial fuel cell

SIMBOLISMOS ALIMENTARES E MANJARES DA NOITE MAIS LONGA DO PORTO: ENTRE O SAGRADO E O PROFANO DAS FESTAS DE SÃO JOÃO

Não tendo a riqueza alimentar do Natal ou da Páscoa, o manjar cerimonial do S. João no Porto, como o de outros santos populares é isso mesmo: popular. Na véspera, sardinha assada, caldo verde, febras de porco, pimentos, pão e muito, muito vinho. O cordeiro salta do colo do santo e é imolado no dia seguinte com batatas assadas e arroz de forno. Mas noutros alimentos, que nesta noite o não são, reside também a simbologia das festas sanjoaninas: erva-cidreira, manjerico e alho-porro, atores principais da noite de S. João, que protegem e transmitem mensagens fraternas. Alimentos simbólicos, como simbólicos são também a água das fontes e o fogo das fogueiras e os balões que iluminam o céu nesta noite de infindável madrugada. É a vivência atual do S. João no Porto que constitui o tema central deste estudo, através de um passeio pela cidade na sua noite mais longa, identificando através desse percurso o que de mais singular a cidade manifesta e oferece, quais os comportamentos sociais e alimentares desta festa e a respetiva simbologia. Palavras-chave: São João. Porto. Festa. Manjerico. Alho-porro.ABSTRACTAlthough it does not have the richness of Christmas or Easter, the ceremonial food of St. John´s holiday in OPorto city is, like other popular saints feasts, exactly that: popular. On 23rd june´s evening, sardines, “caldo verde”, pork fibres, roasted peppers, bread, and much, much wine. The lamb jumps out of St John´s shoulders and is immolated with baked potatoes and rice. But in other nourishments, which in this night are not for eating, also lies the symbolism of St. John´s festivities: lemon balm, basil and leek, main actors of St. John´s night, protect and transmit fraternal messages. Symbolic, like fountain´s water and the fire of bonfires and balloons that light up the sky of this endless night. It is the actual experience of St. John in OPorto the focus of this study, experienced in a city tour in its longest night, identifying through this journey what most unique the city manifests and offers, the social and culinary behaviours this festivity holds and its symbology.Keywords: Saint John.
