The relationship between science, politics, and the media. Remarks from a communication scientific point of view

Die Systeme Wissenschaft, Politik und Massenmedien stehen in einem vielfältigen Interdependenzverhältnis zueinander. Aufgrund ihrer unterschiedlichen Funktionen und Logiken führen die gegenseitigen Abhängigkeiten in den meisten Fällen zu Spannungen und Unzufriedenheiten, wie sie dann zum Beispiel in den Klagen über die PISA-Berichterstattung der Medien ihren Ausdruck finden. (DIPF/Orig.)The relations between the systems of politics, media and science are characterized by a net of interdependencies. Because of the different functions and logics of the three systems, the mutual dependencies lead in most cases to tensions and discontent, which, for instance, is reflected in the complaints about the PISA reporting of the German media.

The EU, the member states and the future of public broadcasting

La Comisión Europea ha venido ejerciendo una considerable presión sobre el sistema público de difusión. El motivo radica en que la Comisión entiende la difusión como cualquier otro servicio y aplica por tanto la regulación en materia de competencia a las cadenas de transmisión independientemente de que tengan intereses comerciales o desarrollen una función de servicio público. Contraria a esta idea, la financiación de la radiodifusión pública hace referencia a aquellas ayudas procedentes del Estado y que sólamente son permitidas en determinadas circunstancias. En los últimos años, varias cadenas privadas de difusión de diferentes países miembros de la Unión Europea se han sentido molestas por esta forma de financiación y han denunciado que las ayudas estatales al servicio público de radiodifusión provocan una distorsión de la competencia. La Comisión se mostró reacia a intervenir pero con el paso del tiempo ha ido adoptanto una postura más comprometida y, finalmente, ha dejado al margen a los estados miembros aunque, de acuerdo con el Protocolo de amsterdam, tienen la competencia para determinar la función del Sistema Público de Difusión y para decidir el modo de financiación. Esta lucha persigue cambiar este sistema, pendiente de definir desde hace más de cincuenta años

Auntie knows best? public broadcasters and current affairs knowledge

Public service broadcasters (PSBs) are a central part of national news media landscapes. In many countries, PSBs are the first choice of citizens when it comes to news providers. And in perhaps more countries still, PSBs are thought of as specialists in provision of hard news. We test this proposition here using survey data from a large crossnational survey involving indicators of current affairs knowledge and media consumption. Specifically, we examine whether exposure to public versus commercial news influences the knowledge citizens possess about current affairs, both domestically and internationally. We also test, using propensity score analysis, whether there is variation across PSBs in this regard. Results indicate that compared to commercial news, watching PSB has a net positive influence on knowledge of hard news, though not all PSBs are equally effective in contributing to knowledge acquisition. This knowledge gap between PSB and commercial news media consumption appears to be mitigated by factors such as de jure independence,proportion of public financing, and audience share

Ergosterol Effect on the Desaturation of 14C-Cis-Vaccenate in Tetrahymena

Supplement of ergosterol to the growth medium of the ciliated protozoan Tetrahymena pyriformis W leads to incorporation of the foreign sterol within cell membranes and suppression of synthesis of the native sterol-like compound tetrahymanol, as well as to changes in the fatty acid compositions of several major classes of membrane lipid. Alteration of fatty acid composition is thought to represent a regulatory mechanism whereby optimum membrane fluidity is maintained when the slightly dissimilar foreign sterol is added into the phospholipid bilayer of the membranes. The present study, using several different conditions of growth temperature, substrate concentrations and incubation time, and ergosterol concentrations and exposure time, is an attempt to provide evidence supporting a hypothetical regulatory mechanism. This mechanism proposes that there is a feedback regulation by membrane-bound sterol on an enzyme or enzymes involved in synthesis of the long chain fatty acids contained in membrane phospholipid. Such a mechanism could account for the balance between sterol and fatty acid content of membrane. The data presented here show that a statistically significant increase in desaturation of 14C-cis-vaccenate can be demonstrated in Tetrahymena cell cultures whose membranes contain the foreign sterol, when growth temperature is maintained at 20° or 29.5°. Tetrahymena desaturated 14C-cis-vaccenate substrate in both ergosterol supplemented and normal cultures. The 14C labeled product, 6,11-18:2 was recovered and separated by silver nitrate-Unisil column chromatography

Political candidates in infotainment programmes and their emotional effects on Twitter: An analysis of the 2015 Spanish general elections pre-campaign season

This is an Accepted Manuscript of an article published by Taylor & Francis in Contemporary Social Science on 2019, available online: http://www.tandfonline.com/10.1080/21582041.2017.1367833.[EN] The infotainment format offers candidates an informal setting to show a more personal side of themselves to the electorate, opening themselves up to potential voters. An example of media hybridisation, social networks users can immediately comment on infotainment television programmes, a process known as second screening. These second screeners tend to be especially active in politics. This paper analyses the immediate emotional reaction of these users as they watch infotainment programmes that air during the campaign or pre-campaign seasons and feature political candidates as guests. We have confirmed that second screeners react more emotionally towards the candidate when his or her party is mentioned, and less emotionally when the host displays an aggressive attitude through his or her non-verbal communication. When issues related to the candidate¿s personal lives are discussed, users¿ emotional reactions improve slightly. The relevance of this research stems from the fact that we are witnessing the consolidation of a politics that increasingly strays from ideological questions, and instead focuses on more emotional and personal issues.This work was supported by the Ministerio de Economia y Competitividad under Grants CSO2013-43960-R and CSO2016-77331-C2-1-R.Baviera, T.; Peris, À.; Cano-Orón, L.

The professionals speak: Practitioners’ perspectives on professional election campaigning

Faced with some fundamental changes in the socio-cultural, political and media environment, political parties in post-industrialized democracies have started to initiate substantial transformations of both their organizational structures and communicative practices. Those innovations, described as professionalization, become most obvious during election campaigns. In recent times, the number of empirical studies measuring the degree of political parties’ campaign professionalism has grown. They have relied on a broad spectrum of indicators derived from theory which have not been tested for their validity. For the first time, we put these indicators to a ‘reality check’ by asking top-ranked party secretaries and campaign managers in 12 European countries to offer their perceptions of professional election campaigning. Furthermore, we investigate whether any differences in understanding professionalism among party campaign practitioners can be explained by macro (country) and meso (party) factors. By and large, our results confirm the validity of most indicators applied in empirical studies on campaign professionalism so far. There are some party- and country-related differences in assessing campaign professionalism too, but the influence of most factors on practitioners’ evaluations is weak. Therefore, we conclude that largely there is a far-reaching European Union-wide common understanding of professional election campaigning

Do voters get it right? A test of the ascription-actuality trait theory of leadership with political elites

Are the traits preferred by voters also associated with success in political office? Drawing on the ascription-actuality trait theory of leadership the present study examines whether traits ascribed to politicians predict leadership outcomes differently to the actual traits they possess. We collected self-ratings of politicians’ personality (N=138) using the NEO-PI-R (actual traits) and observer ratings of politicians’ facial appearance (ascribed traits) to examine their relationship with (a) leadership emergence, measured using share of vote in election, and (b) in-role leadership effectiveness, rated anonymously by political and local authority colleagues. Facial appearance predicted leadership emergence but not effectiveness. Personality had a more nuanced relationship with leadership outcomes. Conscientiousness predicted effectiveness but not emergence, and Agreeableness revealed a trait paradox, positively predicting emergence and negatively predicting effectiveness. These findings suggest a need to understand the contested nature of political leadership and qualities required for different aspects of political roles
