3810 UA: um programa de informação universitária no canal público de televisão de Portugal

No âmbito de uma reestruturação da grelha de programas efectuada no início de 2004, o canal 2 (A DOIS) da empresa Rádio e Televisão de Portugal SGPS (RTP), empresa pública portuguesa para a área do audiovisual, convidou a Universidade de Aveiro, entre outras instituições do Ensino Superior, para o estabelecimento de uma parceria tendo por objectivo a produção de um programa semanal, com a duração de 50 minutos, a ser emitido num espaço diário de divulgação das actividades pedagógicas, científicas e culturais realizadas nas Universidades portuguesas. A Universidade de Aveiro foi a única Universidade pública portuguesa que respondeu afirmativamente a este desafio sem precedentes no Ensino Superior em Portugal. Para pôr de pé este projecto, foi internamente criado um pequeno grupo de trabalho que teve como missão desenvolver o conceito do programa de forma articulada com a estratégia de comunicação institucional da Universidade, que integra outros instrumentos orientados para os diferentes públicos internos e externos baseados em canais diversos, nomeadamente: a comunicação social, a Internet, as publicações periódicas e o contacto directo. O trabalho preparatório de concepção, constituição do núcleo base da equipa e de aquisição e disponibilização dos meios técnicos iniciais decorreu durante os meses de Abril e Maio de 2004, tendo as emissões sido iniciadas no dia 1 de Junho de 2004. Desde essa data o programa tem sido emitido semanalmente, com excepção dos períodos de férias de Agosto e Natal. Nesta comunicação é apresentado e discutido o modelo de programa adoptado, nomeadamente no que respeita à organização da grelha do programa, à estratégia editorial e ao envolvimento de alunos da Universidade na produção e realização, sendo, ainda, apresentada a estrutura da equipa constituída bem como os meios técnicos afectados a este projecto. Finalmente, são apresentados os resultados de audiências e discutidos os principais retornos, para a Universidade de Aveiro, do investimento e trabalho realizados.In the scope of a reorganization of the program schedule carried in 2004, the channel 2 (A DOIS) of Rádio e Televisão de Portugal SGPS, the Portuguese public broadcaster invited the University of Aveiro, among other Higher Education institutions, to establish a partnership aiming at the production of a 50 minutes weekly program, to be broadcasted within a daily space created for promoting pedagogical, scientific and cultural activities carried through at the Portuguese Universities. The University of Aveiro was the only Portuguese public University that accepted this challenge without precedents in Higher Education in Portugal. A small taskforce group was created with the mission to develop the concept of the program articulated with the institutional communication strategy of the University, that integrates other instruments focused on the different internal and external publics. This is achieved through diverse channels, including the social communication, the Internet, the periodic publications and the direct contact. The preparatory work of the development of the program’s concept, the set up of the team’s basic nucleus and the acquisition and installation of the technical infrastructure was carried during the months of April and May 2004. The emissions started on the 1st of June 2004. Since this date the program has been emitted weekly, with the exception of the vacation periods of August and Christmas. The program model adopted is presented and argued in this communication. This includes the organization of the grate of the program, the involvement of the University students in its production, as well as the human and technical resources required. Finally, the results of audiences and the main institutional outcomes are presented and discussed

Why are some prices stickier than others? Firm-data evidence on price adjustment lags

Infrequent price changes at the firm level are now well documented in the literature. However, a number of issues remain partly unaddressed. This paper contributes to the literature on price stickiness by investigating the lags of price adjustments to different types of shocks. We find that adjustment lags to cost and demand shocks vary with firm characteristics, namely the firm’s cost structure, the type of pricing policy, and the type of good. We also document that firms react asymmetrically to demand and cost shocks, as well as to positive and negative shocks, and that the degree and direction of the asymmetry varies across firms.

BioISO: an objective-oriented application for assisting the curation of genome-scale metabolic models

As the reconstruction of Genome-Scale Metabolic Models (GEMs) becomes standard practice in systems biology, the number of organisms having at least one metabolic model is peaking at an unprecedented scale. The automation of laborious tasks, such as gap-finding and gap-filling, allowed the development of GEMs for poorly described organisms. However, the quality of these models can be compromised by the automation of several steps, which may lead to erroneous phenotype simulations. Biological networks constraint-based In Silico Optimisation ( BioISO ) is a computational tool aimed at accelerating the reconstruction of GEMs. This tool facilitates manual curation steps by reducing the large search spaces often met when debugging in silico biological models. BioISO uses a recursive relation-like algorithm and Flux Balance Analysis (FBA) to evaluate and guide debugging of in silico phenotype simulations. The potential of BioISO to guide the debugging of model reconstructions was showcased and compared with the results of two other state-of-the-art gap-filling tools ( Meneco and fastGapFill ). In this assessment, BioISO is better suited to reducing the search space for errors and gaps in metabolic networks by identifying smaller ratios of dead-end metabolites. Furthermore, BioISO was used as Meneco's gap-finding algorithm to reduce the number of proposed solutions for filling the gaps.(undefined)info:eu-repo/semantics/publishedVersio

Salgados – um sítio com produção de ânforas. Contributo para o estudo da ocupação romana no estuário da ribeira de São Lourenço (Almancil – Loulé – Faro)

O sítio arqueológico dos Salgados localiza-se junto à margem esquerda da ribeira de São Lourenço, aproximadamente a 400 m para SE do dique do Ludo. Administrativamente pertence à freguesia de Almancil, concelho de Loulé, a algumas dezenas de metros da linha divisória entre este concelho e o de Faro (Fig. 1). A área com os vestígios arqueológicos situa-se junto a um pequeno olival circundado por um vasto pinhal e pomar de citrinos, sob as coordenadas 7° 59’ 27’’ Long. W e 37° 02’ 53’’ Lat. N. Neste local observam- se inúmeros materiais cerâmicos de cronologia romana à superfície e num corte existente no terreno. Tendo este arqueosítio sido identificado, ocasionalmente, na sequência de um percurso pedestre em Março de 2004, por um grupo de alunos da Universidade do Algarve que deu conhecimento ao Prof. Doutor João Pedro Bernardes, e verificando-se estar o sítio inédito, surgiu a oportunidade e o incentivo para a realização do presente artigo

Diretrizes para prevenção de manifestações patológicas em Habitações de Interesse Social

Os programas habitacionais do governo visam combater o déficit brasileiro que gira em torno de sete milhões de habitações. A preocupação quantitativa, nem sempre articulada com políticas urbanas e sociais, incentiva a produção de conjuntos habitacionais com soluções urbanísticas, arquitetônicas e construtivas repetitivas em larga escala. Diante desta realidade preocupante, o presente estudo visa contribuir para melhorar a qualidade construtiva de empreendimentos habitacionais de interesse social e diminuir o impacto ambiental causado pela sua degradação prematura. A abordagem metodológica adotada foi estudo de caso exploratório. Foi realizada uma investigação das manifestações patológicas no conjunto habitacional Jardim das Palmeiras, situado na cidade de Uberlândia-MG. Neste empreendimento, o sistema construtivo e materiais empregados eram tradicionais, representando as tecnologias típicas da indústria da construção brasileira. As principais contribuições do trabalho referem-se às possíveis origens das manifestações patológicas e à retroalimentação para processo de projeto, gestão da construção e utilização das habitações de interesse social

Bike-sharing mobility patterns: a data-driven analysis for the city of Lisbon

Albuquerque, V., Andrade, F., Ferreira, J. C., Dias, M. S., & Bacao, F. (2021). Bike-sharing mobility patterns: a data-driven analysis for the city of Lisbon. EAI Endorsed Transactions on Smart Cities, 5(16), 1-20. [169580]. https://doi.org/10.4108/eai.4-5-2021.169580New technologies applied to transportation services in the city, enable the shift to sustainable transportation modes making bike-sharing systems (BSS) more popular in the urban mobility scenario. This study focuses on understanding the spatiotemporal station and trip activity patterns in the Lisbon BSS, based in 2018 data taken as the baseline, and understand trip rate changes in such system, that happened in the following years of 2019 and 2020. Furthermore, our paper aims to understand the COVID-19 pandemic impact in BSS mobility patterns. In this paper, we analyzed large datasets adopting a CRISP-DM data mining method. By studying and identifying spatiotemporal distribution of trips through stations, combined with weather factors, we looked at BSS improvements more suitable to accommodate users’ demand. Our major contribution was a new insight on how people move in the city using bikes, via a data science approach using BSS network usage data. Major findings show that most bike trips occur on weekdays, with no precipitation, and we observed a substantial growth of trip count, during the observed time frame, although cut short by the pandemic. We believe that our approach can be applied to any city with available urban mobility data.publishersversionpublishe

Joint Optimal Allocation of Electric Vehicle Charging Stations and Renewable Energy Sources Including CO2 Emissions

In the coming years, several transformations in the transport sector are expected, associated with the increase in electric vehicles (EVs). These changes directly impact electrical distribution systems (EDSs), introducing new challenges in their planning and operation. One way to assist in the desired integration of this technology is to allocate EV charging stations (EVCSs). Efforts have been made towards the development of EVCSs, with the ability to recharge the vehicle at a similar time than conventional vehicle filling stations. Besides, EVs can bring environmental benefits by reducing greenhouse gas emissions. However, depending on the energy matrix of the country in which the EVs fleet circulates, there may be indirect emissions of polluting gases. Therefore, the development of this technology must be combined with the growth of renewable generation. Thus, this proposal aims to develop a mathematical model that includes EVs integration in the distribution system. To this end, a mixed-integer linear programming (MILP) model is proposed to solve the allocation problem of EVCSs including renewable energy sources. The model addresses the environmental impact and uncertainties associated with demand (conventional and EVs) and renewable generation. Moreover, an EV charging forecast method is proposed, subject to the uncertainties related to the driver's behavior, the energy required by these vehicles, and the state of charge of the EVs. The proposed model was implemented in the AMPL modelling language and solved via the commercial solver CPLEX. Tests with a 24-node system allow evaluating the proposed method applicationThe work was supported from FEDER funds through the Operational Programme for Competitiveness and Internationalization (COMPETE2020), under Project POCI-01-0145-FEDER-028983; by National Funds through the FCT Portuguese Foundation for Science and Technology, under Projects PTDC/EEI-EEE/28983/2017(CENERGETIC), CEECIND/02814/2017, and UIDB/000760/2020.

The occidental otaku: Portuguese audience motivations for viewing anime

Japanese animation, widely known as anime, has a global reach. It is simultaneously broadcasted by traditional media and easily distributed and discussed among fans in the digital and online realms. However, non-Japanese audiences’ motivations for watching this kind of content remain almost unstudied in some countries, with Portugal being one of them. This article presents and discusses the outcomes of an online survey completed by 568 respondents, most of them young and regular watchers of anime. A scale by Rubin and Perse (1987), originally used in regard to the audiences of soap operas, was adapted in the scope of this article. Five main motivations were found for anime viewing, with entertainment being the strongest. Age and gender are relevant predictors for the sample’s motivations and also influence audience preferences regarding genres. The survey’s outcomes are complemented by nine in-depth interviews conducted during an anime convention, further exploring the motivations derived from the survey

The Systemic Impacts of a Large-Scale Socio-Environmental Educational Program

In this article we present our findings regarding the systemic impacts of the Environmental Education for the Communities (ECOA) program, an educational program sponsored by the Alcoa Institute. The program, which was developed from 2014 to 2016 in Brazil, involved one corporation (Alcoa Institute), one educational consulting firm (Evoluir), seven Municipal Departments of Education and 30 schools and its surrounding communities. The program promoted environmental awareness following a project-based learning approach: first the students became aware of certain socio-environmental problems in their areas, and then they developed projects to address these problems with support of local communities and guidance from teachers and Evoluir’s educators. Our research objective was to understand the impacts of the program. We followed a qualitative research approach, collecting data by means of document analysis and interviews, unveiling the recurrent themes and analyzing the connections between them by means of a systemic analysis. Our main findings were: 1) The use of the PBL approach, involving schools and communities in joint planning and execution processes, promoted environmental awareness and strengthened the ties between the schools and local communities. 2) The PBL approach challenged the students to solve real-life problems, improving their critical thinking, their communications and problem-solving skills, leading to the improvement of their self-confidence and in their interest in learning. 3) The PBL approach empowered the teachers, motivating them to study and to make connections with community partners, thus changing the ways the courses were conducted and the relationships between school and local communities.Neste artigo, apresentamos nossas conclusões sobre os impactos sistêmicos do programa Educação Ambiental para as Comunidades (ECOA), um programa educacional patrocinado pelo Instituto Alcoa. O programa, desenvolvido de 2014 a 2016 no Brasil, envolveu uma corporação (Instituto Alcoa), uma empresa de consultoria educacional (Evoluir), sete Secretarias Municipais de Educação e 30 escolas e suas comunidades vizinhas. O programa promoveu a conscientização ambiental, seguindo uma abordagem de aprendizagem baseada em projetos (ABP): primeiro, os alunos tomaram conhecimento de problemas socioambientais de suas regiões e, em seguida, desenvolveram projetos para resolver esses problemas, com o apoio das comunidades locais e a orientação de professores e educadores da Evoluir. Nosso objetivo da pesquisa foi entender os impactos do programa. Seguimos uma abordagem qualitativa de pesquisa, coletando dados por meio de análise de documentos e entrevistas, revelando os temas recorrentes e analisando as conexões entre eles por meio de uma análise sistêmica. Nossas principais conclusões foram: 1) O uso da abordagem ABP, envolvendo escolas e comunidades em processos conjuntos de planejamento e execução, promoveu a conscientização ambiental e fortaleceu os laços entre as escolas e as comunidades locais.2) A abordagem ABP desafiou os alunos a resolver problemas da vida real, melhorando seu pensamento crítico, suas habilidades de comunicação e resolução de problemas, levando à melhoria de sua autoconfiança e do interesse em aprender. 3) A abordagem ABP empoderou os professores, motivando-os a estudar e a estabelecer conexões com os parceiros da comunidade, alterando assim a maneira como os cursos eram realizados e as relações entre a escola e as comunidades locais
