Gender in focus: (new) trends in media

(Excerto) Nowadays, the public discourses about gender equality are commonly accepted in Western society. In fact, we live in an era of “equality illusion” (Banyard, 2010) because the mainstream discourses incorporate gender in the agenda, conveying the message that feminist struggles are unnecessary today. At the same time, postfeminism (McRobbie, 2004) gains importance and demonstrates the intricacies of a neoliberal, highly individualist culture that subtly imprisons the freedoms that it is supposed to grant (Gill & Scharff, 2011).

Media(ted) discourse and society: rethinking the framework of critical discourse analysis

The analysis of journalistic discourse and its social embeddedness has known significant advances in the last two decades, especially due to the emergence and development of Critical Discourse Analysis. However, three important aspects remain under-researched: the time plane in discourse analysis, the discursive strategies of social actors, and the extra- and supra-textual effects of mediated discourse. Firstly, understanding the biography of public matters requires a longitudinal examination of mediated texts and their social contexts but most forms of analysis of journalistic discourse do not account for the time sequence of texts and its implications. Secondly, as the media representation of social issues is, to a large extent, a function of the discursive construction of events, problems and positions by social actors, the discursive strategies that they employ in a variety of arenas and channels ‘‘before’’ and ‘‘after’’ journalistic texts need to be examined. Thirdly, the fact that many of the modes of operation of discourse are extra- or supra-textual calls for a consideration of various social processes ‘‘outside’’ the text. This paper aims to produce a theoretical and methodological contribution to the integration of these issues in discourse analysis by proposing a framework that combines a textual dimension with a contextual one

Conversion of Cn-unsaturated into Cn-2-saturated LCFA can occur uncoupled from methanogenesis in anaerobic bioreactors

Fat, oils, and grease present in complex wastewater can be readily converted to methane, but the energy potential of these compounds is not always recyclable, due to incomplete degradation of long chain fatty acids (LCFA) released during lipids hydrolysis. Oleate (C18:1) is generally the dominant LCFA in lipid-containing wastewater, and its conversion in anaerobic bioreactors results in palmitate (C16:0) accumulation. The reason why oleate is continuously converted to palmitate without further degradation via β-oxidation is still unknown. In this work, the influence of methanogenic activity in the initial conversion steps of unsaturated LCFA was studied in 10 bioreactors continuously operated with saturated or unsaturated C16- and C18-LCFA, in the presence or absence of the methanogenic inhibitor bromoethanesulfonate (BrES). Saturated Cn-2-LCFA accumulated both in the presence and absence of BrES during the degradation of unsaturated Cn-LCFA, and represented more than 50\% of total LCFA. In the presence of BrES further conversion of saturated intermediates did not proceed, not even when prolonged batch incubation was applied. As the initial steps of unsaturated LCFA degradation proceed uncoupled from methanogenesis, accumulation of saturated LCFA can be expected. Analysis of the active microbial communities suggests a role for facultative anaerobic bacteria in the initial steps of unsaturated LCFA biodegradation. Understanding this role is now imperative to optimize methane production from LCFA.

Ensino superior, formação de professores e Educação para os Media

Este capítulo propõe-se traçar um retrato da actual situação da Educação para os Media no Ensino Superior em Portugal (público e privado), no que à vertente da formação diz respeito, tentando observar a evolução e as mudanças ocorridas ao longo da primeira década do século XXI. Pretende-se saber se os conteúdos de Educação para os Media estão presentes nos cursos de formação de professores, bem como noutros cursos; se a Educação para os Media integra unidades curriculares (UC) específicas, ou se os conteúdos relaciona-dos estão diluídos em UC´s mais genéricas; se tem presença obrigatória ou opcional; se a área faz parte do currículo formal ou se está integrada em actividades de investigação e/ou de formação, além de outros aspectos que sejam relevantes para a compreensão do quadro geral neste subsector.

Association between coronary artery atherosclerosis and the intima-media thickness of the common carotid artery measured on ultrasonography

OBJECTIVE: To assess whether the intima-media thickness of the common carotid artery of patients with coronary artery disease is greater than that of individuals without that disease. METHODS: Case-control prospective study of prevalence assessing the thickness of the intima and media layers of 29 patients with coronary artery disease and 29 individuals without that disease by using ultrasonography of the carotid arteries. Diabetic patients and those with peripheral artery and cerebral vasculopathies were excluded from the study. RESULTS: The mean age was 51±7.5 years. Fifty-five per cent of the patients were males. Acute myocardial infarction was present in 62%; cardiac catheterization in 72%; saphenous bypass in 5%; and coronary angioplasty in 24%. The intima-media thickness of the common carotid artery in case patients and in control patients was, respectively, 0.81±0.25 mm and 0.62±0.18 mm (P=0.001). CONCLUSION: Intima-media thickness of the common carotid artery was significantly greater in patients with coronary artery disease.

Competencias genéricas en las culturas institucionales de la escuela media: su potencial significación para la educación superior universitaria

El proyecto tematiza la identificación de competencias genéricas (no disciplinarias) originadas en las culturas institucionales de la escuela media con potencial significación para la educación superior universitaria. La necesidad de identificar competencias genéricas en las culturas institucionales de la escuela media encuentra sus antecedentes en algunas investigaciones que, si bien analizan la problemática desde la perspectiva de la articulación Escuela Media – Universidad, focalizan su interés en explorar cuestiones vinculadas al ámbito epistemológico de las disciplinas es decir, al ámbito de las competencias específicas. En este sentido, estos estudios resaltan el déficit en la adquisición por parte de los alumnos de la escuela media de competencias académico-curriculares, particularmente en los conocimientos vinculados con las disciplinas escolares (matemática, lengua, química, física, biología; entre las más atendidas). El estudio posibilitará identificar competencias genéricas construidas en las culturas institucionales de la escuela media con potencial significación para la educación superior universitaria. En otra etapa –no prevista en esta investigación - permitirá el diseño e implementación de un plan de formación para equipos directivos de escuela media y responsables de gestión de educación superior universitaria.
