Much has happened in the past fifty years, and the broadcasting system and in fact the entire media landscape have changed in many significant ways. Yet, the debate on the role of public service media and the involvement of the state in them still perseveres. It has indeed been reinvigorated due to the tectonic shifts in media production, distribution, access and consumption caused by digital technologies in general, and the Internet in particular. The gist of the debates has however curiously remained almost the same and is still focused on a set of economic arguments that call for state intervention in public media, and not unimportantly, on the various political interpretations of these economic arguments. In Europe, the debate has another essential core too, as Public Service Broadcasting (PSB) has been traditionally entrusted to serve some higher goals intrinsically related to key democratic and cultural processes. Accordingly, PSB in Western Europe has developed as the core media institution at the national level and has become deeply embedded in many facets of the nation’s economic, political, social and cultural life. Against the backdrop of PSB’s history, its vital tasks in society, as well as the dramatic changes brought about by the digitally networked environment, the question on the future of PSB and its transition into Public Service Media (PSM) is very interesting, to say the least, and highly challenging at the same time. The book by Karen Donders, Public Service Media and Policy in Europe (Palgrave, 2012), makes an essential contribution to these complex debates, and more importantly, adds some new value to an otherwise saturated discourse.

Reactive oxygen species (ROS) production is important in the toxicity of pathogenic particles such as fibres. We examined the oxidative potential of straight (50 microm and 10 microm) and tangled carbon nanotubes in a cell free assay, in vitro and in vivo using different dispersants. The cell free oxidative potential of tangled nanotubes was higher than for the straight fibres. In cultured macrophages tangled tubes exhibited significantly more ROS at 30 min, while straight tubes increased ROS at 4 h. ROS was significantly higher in bronchoalveolar lavage cells of animals instilled with tangled and 10 mum straight fibres, whereas the number of neutrophils increased only in animals treated with the long tubes. Addition of dispersants in the suspension media lead to enhanced ROS detection by entangled tubes in the cell-free system. Tangled fibres generated more ROS in a cell-free system and in cultured cells, while straight fibres generated a slower but more prolonged effect in animals.

Cultural protectionism has been an element of national and foreign policies, as an extension of state sovereignty expressed both in a defensive and offensive manner. While the generic protectionist formula in the sense of restraining trade between states through measures such as import tariffs or quotas and through privileging domestic production has somewhat disintegrated over time under the rationale for free trade and the strong practical evidence of its benefits, the particular case of cultural protectionism has persevered. As we reveal in this paper, however, it has been modified, or at least its rhetoric has changed. The enquiry into the notion of cultural protectionism or cultural diversity, as the current political jargon would have it, is but one of the paper’s objectives. Its second and certainly more ambitious goal is the search for the normative dimensions of cultural diversity policies in the global digital space, asking what adjustments are needed and how feasible the entire project of diversity regulation in this environment may be. Taking into account the specificities of cyberspace and in a forward-looking manner, we propose some adjustments to current media policy practices that could better serve the goal of a sustainably diverse cultural environment.

BACKGROUND Type D personality (Type D) is an independent psychosocial risk factor for poor cardiac prognosis and increased mortality in patients with cardiovascular disease (CVD), but the involved mechanisms are poorly understood. Macrophages play a pivotal role in atherosclerosis, the process underlying coronary artery disease (CAD). We investigated macrophage superoxide anion production in production in CAD patients with and without Type D. METHODS AND RESULTS We studied 20 male CAD patients with Type D (M:66.7±9.9years) and 20 age-matched male CAD patients without Type D (M:67.7±8.5years). Type D was measured using the DS14 questionnaire with the two subscales 'negative affectivity' and 'social inhibition'. We assessed macrophage superoxide anion production using the WST-1 assay. All analyses were controlled for potential confounders. CAD patients with Type D showed higher superoxide anion production compared to CAD patients without Type D (F(1,38)=15.57, p<0.001). Complementary analyses using the Type D subscales 'negative affectivity' and 'social inhibition', and their interaction as continuous measures, showed that both Type D subscales (negative affectivity: (ß=0.48, p=0.002, R(2)=0.227); social inhibition: (ß=0.46, p=0.003, R(2)=0.208)) and their interaction (ß=0.36, p=0.022, R(2)=0.130) were associated with higher WST-1 reduction scores. Results remained significant when controlling for classical CVD risk factors (i.e. body mass index, mean arterial blood pressure), atherosclerosis severity (i.e. intima media thickness, presence of carotid plaques), and psychological factors (depressive symptom severity, chronic stress). CONCLUSIONS Our results indicate higher macrophage superoxide anion production in CAD patients with Type D compared to those without Type D. This may suggest a mechanism contributing to increased morbidity and mortality in CAD patients with Type D.

This presentation is about the inside story of the PhD project El malagueño real, mental y virtual. Configuración de los significados sociales de una variedad urbana in Hispanic Linguistics. That is, the production and perception of the Spanish spoken in the city of Malaga and used on the social network sites Facebook and Tuenti by users from Malaga is analysed. Actually, the southern Spanish variety in question is quite distinct from the national standard in terms of its phonetic features, its prestige, and the attitudes to it. Thus, the project started with the initial interest in «Why do people often communicate in very “strange” ways on social media» which then slightly changed to the final research interest in «What do the different non-standard variants mean in virtual (and real) malagueño?». This long – sometimes hazardous, yet mostly fun – process is exposed in more detail by looking at the research questions, the methods and results. Lastly, the presentation concludes with some lessons learnt and an outlook on possibilities and necessities for further investigation.
