Perceções sociais dos portugueses face aos riscos associados às alterações climáticas

O aquecimento do sistema climático é inequívoco e a influência humana é clara. A continuação da emissão de gases com efeito de estufa irá potenciar os impactes das alterações climáticas, representando um compromisso futuro que se perpetuará por vários séculos. As alterações climáticas não proporcionam uma experiência sensorial direta, embora as variações de temperatura e de precipitação e os extremos climáticos de vários tipos poderem ser experienciados. O cidadão comum não se apercebe do que está a acontecer, a menos que ocorram mudanças significativas, no estado normal do tempo para uma determinada época, na região do mundo onde ele vive. Mesmo para os especialistas, o problema só é cognoscível através de uma vasta rede científica, técnica e institucional. O conhecimento, é portanto, transmitido ao público em geral maioritariamente através de representações dos media sobre o discurso produzido pela comunidade científica. O principal objetivo deste trabalho é averiguar a interligação entre o discurso científico, o discurso mediático e as perceções da população portuguesa na temática das alterações climáticas. A metodologia utilizada, para a prossecução do objetivo, num trabalho que cruza o domínio científico da engenharia do ambiente com o das ciências sociais, encontra-se dividida em 3 fases principais: (1) Uma primeira fase onde se realiza uma análise ao discurso científico de produção nacional, com uma análise de conteúdo aos resumos dos artigos científicos, utilizando 884 resumos da base de dados Scopus de 1975 a 2013 com a palavra-chave ‘Climate Change’; (2) Uma segunda fase onde se analisa o conteúdo de notícias de meios de comunicação social portugueses, aplicando uma análise de conteúdo a 4340 notícias veiculadas por 4 órgãos de comunicação social (Correio da Manhã, Público, RTP e TSF) entre 2004 e 2013, utilizando os respetivos motores de busca online com a palavra-chave ‘Alterações Climáticas’; e, (3) uma terceira fase onde se compila a informação dos estudos existentes sobre a população portuguesa, utilizando os dados dos Eurobarómetros que incluem o tema das alterações climáticas de 1982 a 2014. Seguindo uma linha condutora que inclui o discurso científico, o discurso mediático e as perceções sociais, almejou-se uma abrangência do tema das alterações climáticas, investigando a existência do fenómeno e as respetivas causas, as consequências com a análise dos impactes e dos riscos associados a esses impactes e as soluções através de medidas de mitigação e de adaptação. Nos principais resultados emerge a evidência de que a intensidade de crescimento da produção científica nacional não se traduz num crescimento consistente dos índices de noticiabilidade dos órgãos de comunicação social e desde 2010 que o número de dias por ano, sem notícias sobre alterações climáticas, ultrapassa dos 50%. Em consequência, os níveis de informação da população portuguesa sobre as alterações climáticas são sistematicamente inferiores à média europeia. Em Portugal as taxas de pouco ou nulo conhecimento rondam os dois terços de inquiridos. Não obstante o seu caráter contínuo, para que as alterações climáticas se tornem alvo de interesse dos media é necessário que ocorram reuniões políticas, encontros científicos ou outros acontecimentos. A visibilidade alcançada pelos acontecimentos nacionais é muito fraca e os acontecimentos meteorológicos extremos, não são frequentemente relacionados com o fenómeno das alterações climáticas. No seio da comunidade científica portuguesa existe um claro consenso sobre a existência das alterações climáticas e das suas causas antropogénicas. No discurso mediático português não se verifica enviesamento da informação não sendo surpreendente os baixos níveis de ceticismo dos portugueses. A abordagem aos impactes das alterações climáticas, tanto no discurso científico como no discurso mediático, é robusta e em 2014, cerca de sete em dez portugueses afirma que as alterações climáticas são um problema muito sério. Contudo, Portugal apresenta a proporção mais baixa da Europa de respondentes que percepcionam as alterações climáticas como o problema mais grave que o mundo enfrenta. Para estes resultados poderá contribuir a baixa inclusão de termos relacionados com o risco, tanto no discurso científico como no mediático, não ultrapassando os 20%. Tanto o discurso científico como o discurso mediático não estão direcionados para as soluções (mencionando especificamente medidas de mitigação ou medidas de adaptação). A menção às medidas de mitigação e às medidas de adaptação não ultrapassam os 16% no discurso científico e apresentam valores ainda mais baixos no discurso mediático (13%). Em ambos os discursos existe uma clara preferência pela menção às medidas de adaptação em detrimento das medidas de mitigação. Com valores tão baixos na abordagem às soluções das alterações climáticas não surpreendem os também diminutos níveis de responsabilidade que a população portuguesa atribui a si própria no combate às alterações climáticas.

Four-month-olds make triangular bids to father and mother during trilogue play with still-face

(from the journal abstract) A new observational procedure, Trilogue Play with Still-face, revealed 4-month-olds' capacities to address both their fathers and mothers, by rapidly shifting gaze and affect between them. Infants were observed in four interactive contexts: (1) '3-together' play with both parents; (2) '2 + 1' play with one parent engaging and the other as third party; (3) the same, with one parent posing a still-face; (4) '3-together' play. Infants were able to discriminate between the four contexts. They coordinated three social poles of attention in each one. Their affect configurations were context sensitive. These findings demonstrate the infant's social capacities for triangular, three-person interactions, in addition to dyadic, two-person, and triadic, two-person plus object, ones. They support a view of intersubjectivity as primary and point to a promising field of investigation for the study of family process. (PsycINFO Database Record (c) 2005 APA, all rights reserved)

Comparing ESL electronic and face-to-face pre-writing conferences and first drafts : discourse, participation, and idea transfer /

This study was a comparative investigation of face-toface (i.e., proximate) and computer-mediated written (i.e., graphic) pre-writing conferences. The participants in this study were advanced English as a second language students. The 2 types of conferences were compared in terms of textual features, participation, and the . degree to which they were on topic. Moreover, drafts written after the 2 types of conferences were compared in terms of textual features, and the degree to which they were related to the conferences. Students produced an equivalent amount of discourse in an equivalent amount of time in the 2 types of conferences. The discourse in graphic conferences displayed greater lexical range, and some evidence suggests that it was less on-topic. Both these results likely occurred because the graphic conferences contained more discourse demonstrating interactive competence. Participation in graphic conferences was found to be as balanced or more balanced among students, and among students and the group leader combined. Overall, the drafts produced after the 2 types of conferences were of equivalent length and topical range, but some evidence suggests that drafts written after proximate conferences were more related to the conferences.

Effects of computer-mediated communication and face-to-face communication on the quantity and quality of discourse produced by English as a second language students /

The effects oftwo types of small-group communication, synchronous computer-mediated and face-to-face, on the quantity and quality of verbal output were con^ared. Quantity was deiSned as the number of turns taken per minute, the number of Analysis-of-Speech units (AS-units) produced per minute, and the number ofwords produced per minute. Quality was defined as the number of words produced per AS-unit. In addition, the interaction of gender and type of communication was explored for any differences that existed in the output produced. Questionnaires were also given to participants to determine attitudes toward computer-mediated and face-to-face communication. Thirty intermediate-level students fi-om the Intensive English Language Program (lELP) at Brock University participated in the study, including 15 females and 15 males. Nonparametric tests, including the Wilcoxon matched-pairs test, Mann-Whitney U test, and Friedman test were used to test for significance at the p < .05 level. No significant differences were found in the effects of computer-mediated and face-to-face communication on the output produced during follow-up speaking sessions. However, the quantity and quality of interaction was significantly higher during face-to-face sessions than computer-mediated sessions. No significant differences were found in the output produced by males and females in these 2 conditions. While participants felt that the use of computer-mediated communication may aid in the development of certain language skills, they generally preferred face-to-face communication. These results differed fi-om previous studies that found a greater quantity and quality of output in addition to a greater equality of interaction produced during computer-mediated sessions in comparison to face-to-face sessions (Kern, 1995; Warschauer, 1996).

Learning and Experiential Outcomes of Face-to-Face Versus Online Communications Courses

Higher education is rapidly trending toward the implementation of online (OL) courses and a blended facilitation style that incorporates both OL and face-to-face (FTF) classes. Though previous studies have explored the benefits and pitfalls of OL and blended learning formats from institutional, teacher, and student perspectives, scant research has examined learning outcomes for OL and FTF courses sharing identical content. This study used an explanatory mixed methods design—including pre- and post-test assessments, a questionnaire, and interviews—to explore similarities and differences in participant and teacher perceptions and outcomes (gain scores and final grades) of OL versus traditional FTF Communications courses, and to examine effects of students’ age and gender on learning preference and performance. Data collection occurred over a 4-month period and involved 183 student and 2 professor participants. The study used an SPSS program for data analysis and created a Microsoft Excel document to record themes derived from the questionnaire and interviews. Quantitative findings suggest there are no significant differences in gain scores, final grades, or other learning outcomes when comparing OL and FTF versions of identical Communications courses; however, qualitative findings indicate differences between facilitation styles based on student and professor perception. The study sheds light on student and faculty perceptions of facilitation styles and suggests areas for potential improvements in FTF- and OL-facilitated courses. The study ultimately recommends that students and faculty should have options when it comes to preferred delivery of course material.

Flourishing in the face of mental illness: A heuristic examination of the contribution of leisure to creating a meaningful life

The purpose of this research was to examine the ways in which individuals with mental illness create a life of purpose, satisfaction and meaning. The data supported the identification of four common themes: (1) the power of leisure in activation, (2) the power of leisure in resiliency, (3) the power of leisure in identity and (4) the power of leisure in reducing struggle. Through an exploration of the experience of having a mental illness, this project supports that leisure provides therapeutic benefits that transcend through negative life events. In addition, this project highlights the individual nature of recovery as a process of self-discovery. Through the creation of a visual model, this project provides a benchmark for how a small group of individuals have experienced living well with mental illness. As such, this work brings new thought to the growing body of mental health and leisure studies literature.

“This wasn’t supposed to happen” : making sense of emotions in the face of expectation breach

Des recherches antérieures sur les émotions en contexte organisationnel, notamment autour des notions de travail émotionnel, de contrat psychologique et d'équité, ont souvent soulevé la question de la rationalité et du caractère approprié ou non des manifestations émotionnelles, ainsi que sur les mécanismes utilisés pour contrôler et modérer celles-ci. Cependant, peu de recherche empirique a été effectuée sur la façon dont les employés eux-mêmes font sens de leurs émotions au travail et le processus par lequel ils parviennent à rendre celle-ci compréhensibles et légitimes, à la fois pour eux-mêmes et pour autrui. Au cours des dernières années, un courant de recherche émergent tend toutefois à mettre de côté la perspective normative / rationaliste pour soulever ce type de questions. Ainsi, au lieu d'être considérées comme des expériences strictement subjectives, privées, voire inaccessibles, les émotions y sont envisagées à travers les discours et les mises en récits dont elles font l’objet. Les émotions apparaissent ainsi non seulement exprimées dans le langage et la communication, mais construites et négociées à travers eux. La recherche présente développe empiriquement cette perspective émergente, notamment en faisant appel aux théories du sensemaking et de la narration, à travers l’analyse détaillée des récits de quatre employés chargés du soutien à la vente pour un revendeur de produits informatiques. En demandant à mes sujets de parler de leurs expériences émotionnelles et en analysant leurs réponses selon une méthodologie d’analyse narrative, cette recherche explore ainsi la façon dont les employés parviennent à construire le sens et la légitimité de leurs expériences émotionnelles. Les résultats suggèrent entre autres que ces processus de construction de sens sont très étroitement liés aux enjeux d’identité et de rôle.

Relative Contributions of Internal and External Features to Face Recognition

The central challenge in face recognition lies in understanding the role different facial features play in our judgments of identity. Notable in this regard are the relative contributions of the internal (eyes, nose and mouth) and external (hair and jaw-line) features. Past studies that have investigated this issue have typically used high-resolution images or good-quality line drawings as facial stimuli. The results obtained are therefore most relevant for understanding the identification of faces at close range. However, given that real-world viewing conditions are rarely optimal, it is also important to know how image degradations, such as loss of resolution caused by large viewing distances, influence our ability to use internal and external features. Here, we report experiments designed to address this issue. Our data characterize how the relative contributions of internal and external features change as a function of image resolution. While we replicated results of previous studies that have shown internal features of familiar faces to be more useful for recognition than external features at high resolution, we found that the two feature sets reverse in importance as resolution decreases. These results suggest that the visual system uses a highly non-linear cue-fusion strategy in combining internal and external features along the dimension of image resolution and that the configural cues that relate the two feature sets play an important role in judgments of facial identity.
