Investigação em Jornalismo: desafios e linhas de pesquisa no século XXI

Propomo-nos, com este artigo, mapear os principais desafios e linhas de pesquisa que marcam hoje os estudos sobre o jornalismo. Desta forma, tentaremos estimular os estudantes de jornalismo, e não só, a eleger as suas linhas de pesquisa e objectos de análise para a elaboração dos projectos de licenciatura e também para futuras incursões académicas, nomeadamente sob a forma de mestrados e doutoramentos.In this article are indentified and discussed the main challenges and research lines that mark the field of journalism in the present time. This way we try to encourage journalism students to elect their research lines and objects of analysis in the context of their courses, also considering future academic incursions, particularly in the form of master's and doctoral degrees

Novos media e domesticação

Artigo baseado na comunicação proferida no 5º Congresso SOPCOM: Comunicação e Cidadania, realizado na Universidade do Minho, Braga, Portugal, 06-07 de setembro de 2007Domesticação é uma metáfora que traduz o jogo de forças que se estabelece entre diferentes meios de comunicação e os seus utilizadores. Apesar de podermos assumir que o indivíduo domestica os media e que estes domesticam o indivíduo, importa perguntar se os chamados novos media obrigam a novas formas de domesticação e a um efectivo reforço da responsabilidade individual da sua utilização.info:eu-repo/semantics/publishedVersio

Towards an interpretation of the Portuguese cultural tourist: motivations and constraints

The importance of cultural tourism for the development of tourist destinations has created a need for knowledge on both supply and demand sides, related to the motivations and constraints which can affect the decisions of the cultural tourist. The aim of this study is to develop and validate for the Portuguese tourists two scales to measure motivations to travel and its constraints, considering theories of needs and constraints, and to examine differences according to tourists’ socio-demographic characteristics. The scales were determined using a non-linear principal component analysis followed by bootstrap confirmatory factor analysis, and differences were examined using parametric tests. A six-dimensional model for motivations and a five-dimensional model for constraints were validated, both with good overall fit. Motives linked to culture, intellectual curiosity and cultural knowledge stand out with high levels of relevance. Lack of resources and other commitments are the most important constraints. Significant differences were found in almost all characteristics. The results reveal influential dimensions on travel decisions which are of utmost importance for the design of the cultural offer of destinations.info:eu-repo/semantics/publishedVersio

As eleições de Cabo Verde (2016) nos média portugueses generalistas

Neste texto apresentam-se e discutem-se os resultados de uma investigação sobre a cobertura jornalística dos três atos eleitorais de Cabo Verde (2016) – eleições legislativas, eleições autárquicas e eleições presidenciais –, realizada pelos média portugueses generalistas. Concluímos que, se dependessem dos média portugueses analisados – RTP1, SIC, TVI, TSF, Antena1, Rádio Renascença, Público, Correio da Manhã, Expresso – para saberem o que esteve em causa nessas eleições, os portugueses e os cabo-verdianos residentes em Portugal teriam pouco mais do que a informação sobre os resultados das respetivas votações. Ou seja, a investigação dá conta de uma ausência de investimento na produção jornalística sobre três momentos relevantes para a vida de um país com uma forte relação histórica, linguística e cultural com Portugal. A estabilidade democrática do país afigura-se como um dos factores determinantes da fraca projeção mediática, comparativamente à situação de instabilidade política e social vivida por outros países africanos

O jornalismo visual em Portugal: contributos para uma história

Este trabalho é financiado por fundos nacionais através da FCT – Fundação para a Ciência e a Tecnologia, I.P., no âmbito do projeto PTDC/COM-JOR/28144/2017 – Para uma história do jornalismo em Portugal.Este livro reúne contributos resultantes de investigações realizadas no âmbito do projeto Para uma História do Jornalismo em Portugal (FCT- -PTDC/COM-JOR/28144/2017). Na primeira parte, tenta-se perceber como é que as imagens ocupam as páginas dos títulos mais relevantes da imprensa ilustrada, no período que medeia entre o fim da I República e os primeiros anos do Estado Novo (1926-1940), fortemente marcado pela censura, e de que modo o trabalho dos fotógrafos traduz o contexto político e as condições de exercício da profissão, na época. No 25 de Abril de 1974, qual foi o papel exercido pelos fotógrafos ao serviço de jornais e revistas, que transformações enfrentaram as editorias de foto- grafia na pós -revolução, com o aparecimento de alguma imprensa inspi- rada nas principais publicações europeias, e como tem evoluído o fotojornalismo nacional até ao presente.info:eu-repo/semantics/publishedVersio

Técnicas combinadas no fechamento de lesões em membros torácico e pélvico de um felino: Relato de caso: Combined techniques in the closure of a feline forelimb and pelvic limb injury: A case report

O objetivo desse trabalho é relatar o uso de técnicas combinadas de curativo em membros torácico e pélvico de um felino, além de desbridamento cirúrgico, após ter sido atropelado, contrariando a indicação primária de amputação de ambos os membros como resolução para as lesões apresentadas e comparar as técnicas e abordagens em feridas aplicadas no caso relatado, com a literatura consultada. No primeiro atendimento as lesões foram limpas, o animal medicado e liberado com prescrição medicamentosa e orientações para curativos. Após dois dias, o animal retornou com os membros edemaciados e sinais de sepse, procedeu-se então, a internação do felino, realização de exames de imagem e laboratoriais, sendo iniciado um protocolo medicamentoso e preparo para o desbridamento cirúrgico. Após o procedimento, foram realizados curativos com o uso de soro fisiológico 0,9% morno, o uso do polihexametileno biguanida (PHMB) e do alginato de cálcio com prata durante toda a fase aguda da lesão. Após a diminuição do exsudato, passou-se a utilizar a pomada sulfadiazina de prata 1% até a completa cicatrização das lesões. Durante toda a internação, o paciente recebeu analgesia antes das trocas de curativo. Após três meses, as lesões foram completamente cicatrizadas e não houve a necessidade de amputação e o animal manteve comportamento e hábitos muito próximos aos animais saudáveis. Dessa forma a técnica empregada com os curativos escolhidos mostrou-se efetivas

Fibrosis of Peritoneal Membrane, Molecular Indicators of Aging and Frailty Unveil Vulnerable Patients in Long-Term Peritoneal Dialysis

Funding: Sociedade Portuguesa de Nefrologia (SPN) SPN funded a project and Ana Rita Martins, MD, Nephrology fellow, for a residence at Jiménez Díaz Foundation University Hospital, Madrid under the scope of novel serum biomarkers of CKD. iNOVA4Health research program (UIDP/04462/2020) is also acknowledged to support J.M.Peritoneal membrane status, clinical data and aging-related molecules were investigated as predictors of long-term peritoneal dialysis (PD) outcomes. A 5-year prospective study was conducted with the following endpoints: (a) PD failure and time until PD failure, (b) major cardiovascular event (MACE) and time until MACE. A total of 58 incident patients with peritoneal biopsy at study baseline were included. Peritoneal membrane histomorphology and aging-related indicators were assessed before the start of PD and investigated as predictors of study endpoints. Fibrosis of the peritoneal membrane was associated with MACE occurrence and earlier MACE, but not with the patient or membrane survival. Serum α-Klotho bellow 742 pg/mL was related to the submesothelial thickness of the peritoneal membrane. This cutoff stratified the patients according to the risk of MACE and time until MACE. Uremic levels of galectin-3 were associated with PD failure and time until PD failure. This work unveils peritoneal membrane fibrosis as a window to the vulnerability of the cardiovascular system, whose mechanisms and links to biological aging need to be better investigated. Galectin-3 and α-Klotho are putative tools to tailor patient management in this home-based renal replacement therapy.publishersversionpublishe

This is an open access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly citedThe objective of this study was to assess whether clinical measures of rheumatoid arthritis activity and severity were influenced by tumor necrosis factor-alpha (TNF-alpha) promoter genotype/haplotype markers. Each patient's disease activity was assessed by the disease activity score using 28 joint counts (DAS28) and functional capacity by the Health Assessment Questionnaire (HAQ) score. Systemic manifestations, radiological damage evaluated by the Sharp/van der Heijde (SvdH) score, disease-modifying anti-rheumatic drug use, joint surgeries, and work disability were also assessed. The promoter region of the TNF-alpha gene, between nucleotides -1,318 and +49, was sequenced using an automated platform. Five hundred fifty-four patients were evaluated and genotyped for 10 single-nucleotide polymorphism (SNP) markers, but 5 of these markers were excluded due to failure to fall within Hardy-Weinberg equilibrium or to monomorphism. Patients with more than 10 years of disease duration (DD) presented significant associations between the -857 SNP and systemic manifestations, as well as joint surgeries. Associations were also found between the -308 SNP and work disability in patients with more than 2 years of DD and radiological damage in patients with less than 10 years of DD. A borderline effect was found between the -238 SNP and HAQ score and radiological damage in patients with 2 to 10 years of DD. An association was also found between haplotypes and the SvdH score for those with more than 10 years of DD. An association was found between some TNF-alpha promoter SNPs and systemic manifestations, radiological progression, HAQ score, work disability, and joint surgeries, particularly in some classes of DD and between haplotypes and radiological progression for those with more than 10 years of DD.This work was supported by grant POCTI/SAU-ESP/59111/2004 from Fundação Ciência e Tecnologia.info:eu-repo/semantics/publishedVersio

Biology and conservation of freshwater bivalves : past, present and future perspectives

Freshwater bivalves have been highly threatened by human activities, and recently their global decline has been causing conservational and social concern. In this paper, we review the most important research events in freshwater bivalve biology calling attention to the main scientific achievements. A great bias exists in the research effort, with much more information available for bivalve species belonging to the Unionida in comparison to other groups. The same is true for the origin of these studies, since the publishing pattern does not always correspond to the hotspots of biodiversity but is concentrated in the northern hemisphere mainly in North America, Europe and Russia, with regions such as Africa and Southeast Asia being quite understudied. We also summarize information about past, present and future perspectives concerning the most important research topics that include taxonomy, systematics, anatomy, physiology, ecology and conservation of freshwater bivalves. Finally, we introduce the articles published in this Hydrobiologia special issue related with the International Meeting on Biology and Conservation of Freshwater Bivalves held in 2012 in Braganc¸a, Portugal.We would like to express our gratitude to our sponsors and institutions, especially to the Polytechnic Institute of Braganca for all the logistic support. We acknowledge all keynote speakers, authors, session chairpersons and especially to all attendees whose contributions were fundamental for the success of this meeting. We would also like to thank all referees of this special issue and to Koen Martens, Editor-in-Chief of Hydrobiologia, for all the valuable comments and suggestions. The chronogram was built with the help of the expert opinion of fellow colleagues Rafael Araujo, Arthur Bogan, Kevin Cummings, Dan Graf, Wendell Haag, Karl-Otto Nagel and David Strayer to whom we are very grateful.
