This time I’m (not) voting: how campaign factors affect European citizens’ turnout in EP elections
Turnout in European Parliament elections declined in every vote held between 1979 and 2014. Ahead of the 2019 elections, the EU launched an initiative, ‘This time I’m voting’, in the hope of raising public interest. While turnout did increase in the 2019 contest, it remains an open question as to whether such campaign efforts help mobilise citizens. Drawing on a new study, Franziska Marquart, Andreas C. Goldberg and Claes H. de Vreese assess the role of individuals’ passive exposure to and active engagement with the 2019 campaign, finding that not all campaign efforts helped to increase turnout, with some even serving to demobilise the European electorate
“Cross-editing”: Comparing News Output Through Journalists’ Re-working of Their Rivals’ Scripts
Newsdesk journalists make thousands of editorial decisions every day without recourse to style guides. They can do this because they have internalised the aims and values of their news organisations: they know what counts as a “good story” for their output. This paper describes a pioneering micro-level comparative method of studying journalistic values in which, unlike in other comparative studies, the journalists themselves perform the initial analysis. In essence, newsdesk editors from two news organisations swap scripts. They evaluate, edit and mark up their rivals’ texts as if they were being asked to use them in their own output. What would they alter, insert or leave out? Would they reject a story completely? This “cross-edit” and the editors’ additional observations represent unmediated analysis from inside the news editing process, allowing researchers to draw comparative conclusions grounded principally in discourse analysis. To pilot the method, a number of journalists from the BBC and China’s official English-language news provider, CCTV-News (now CGTN), cross-edited selected news scripts published by their rivals. The technique shed new light on news routines, lexical choices, omissions and unexpected consonances in news values. It was then refined to provide a framework for future, wider use
Framing immigration and integration: Relationships between press and parliament in the Netherlands
This article examines how the salience and framing of political issues in the press and in parliament influence each other and how this salience and framing is influenced by key events outside the media and parliamentary realms. The case focused on is the debate on immigration and integration in the Netherlands between 1995 and 2004. The empirical analyses are based on a computer-assisted content analysis of both parliamentary documents and newspaper articles. Results show bidirectional causal relationships between media and parliament. In the case of salience only long-term influence relationships are found, while framing influences follow an interesting pattern: an increase in the use of a frame in one arena leads to an increase in the other arena only if this frame has already been used regularly in the latter arena. External events have more considerable and consistent impact on issue salience and framing in both arenas. Copyright © 2007 Sage Publications
Vivid visual mental imagery in the absence of the primary visual cortex
The role of the primary visual cortex in visual mental imagery has provided significant debate in the imagery literature. Functional neuroimaging studies show considerable variation depending on task and technique. Patient studies can be difficult to interpret due to the diverse nature of cortical damage. The type of cortical damage in patient SBR is exceedingly rare as it is restricted to the gray matter of the calcarine sulcus. In this study, we show that in spite of his near-complete cortical blindness, SBR exhibits vivid visual mental imagery both behaviorally and when measured with functional magnetic resonance imaging. The pattern of cortical activation to visual mental imagery in SBR is indistinguishable from individual sighted subjects, in contrast to the visual perceptual responses, which are greatly attenuated
Alternative Oxidase Dependent Respiration Leads to an Increased Mitochondrial Content in Two Long-Lived Mutants of the Ageing Model Podospora anserina
The retrograde response constitutes an important signalling pathway from mitochondria to the nucleus which induces several genes to allow compensation of mitochondrial impairments. In the filamentous ascomycete Podospora anserina, an example for such a response is the induction of a nuclear-encoded and iron-dependent alternative oxidase (AOX) occurring when cytochrome-c oxidase (COX) dependent respiration is affected. Several long-lived mutants are known which predominantly or exclusively respire via AOX. Here we show that two AOX-utilising mutants, grisea and PaCox17::ble, are able to compensate partially for lowered OXPHOS efficiency resulting from AOX-dependent respiration by increasing mitochondrial content. At the physiological level this is demonstrated by an elevated oxygen consumption and increased heat production. However, in the two mutants, ATP levels do not reach WT levels. Interestingly, mutant PaCox17::ble is characterized by a highly increased release of the reactive oxygen species (ROS) hydrogen peroxide. Both grisea and PaCox17::ble contain elevated levels of mitochondrial proteins involved in quality control, i. e. LON protease and the molecular chaperone HSP60. Taken together, our work demonstrates that AOX-dependent respiration in two mutants of the ageing model P. anserina is linked to a novel mechanism involved in the retrograde response pathway, mitochondrial biogenesis, which might also play an important role for cellular maintenance in other organisms
Explanatory pluralism in the medical sciences: theory and practice
Explanatory pluralism is the view that the best form and level of explanation depends on the kind of question one seeks to answer by the explanation, and that in order to answer all questions in the best way possible, we need more than one form and level of explanation. In the first part of this article, we argue that explanatory pluralism holds for the medical sciences, at least in theory. However, in the second part of the article we show that medical research and practice is actually not fully and truly explanatory pluralist yet. Although the literature demonstrates a slowly growing interest in non-reductive explanations in medicine, the dominant approach in medicine is still methodologically reductionist. This implies that non-reductive explanations often do not get the attention they deserve. We argue that the field of medicine could benefit greatly by reconsidering its reductive tendencies and becoming fully and truly explanatory pluralist. Nonetheless, trying to achieve the right balance in the search for and application of reductive and non-reductive explanations will in any case be a difficult exercise
Motor-Skill Learning in Alzheimer’s Disease: A Review with an Eye to the Clinical Practice
Since elderly people suffering from dementia want to go on living independently for as long as possible, they need to be able to maintain familiar and learn new practical skills. Although explicit or declarative learning methods are mostly used to train new skills, it is hypothesized that implicit or procedural techniques may be more effective in this population. The present review discusses 23 experimental studies on implicit motor-skill learning in patients with Alzheimer’s disease (AD). All studies found intact implicit motor-learning capacities. Subsequently, it is elaborated how these intact learning abilities can be exploited in the patients’ rehabilitation with respect to the variables ‘practice’ and ‘feedback.’ Recommendations for future research are provided, and it is concluded that if training programs are adjusted to specific needs and abilities, older people with AD are well able to (re)learn practical motor skills, which may enhance their autonomy
