The coverage of politics, and more specifically policies or political issues, in news media has been abundantly studied by scholars of agenda setting (see for example, McCombs and Shaw, 1972, 1993; Baumgartner and Jones, 2010, 1991; Soroka, 1999; Walgrave and Van Aelst, 2016; Vliegenthart and Walgrave, 2011; Walgrave and Van Aelst, 2016; Baumgartner et al., 2006). Building on Walter Lippmann’s (1957) argument of the media’s ability to construct social realities in the public mind, agenda setting refers to the transfer of often covered topics in news media to its salience in the public agenda. McCombs and Shaw (1972) pioneered this field, surveying voters in North Carolina (USA) on the most important political issues and comparing these results to a media content analysis of nine local news media outlets. This finding has been coined the first-level agenda setting theory. Ever since the seminal study of McCombs and Shaw (1972), this finding has been replicated hundreds of times all across the world – ranging from other locations in the USA, to Europe, Asia, Latin America and Australia – for both election and non-election settings over a broad range of public issues and other aspects of political communication. Moreover, the agenda-setting theory has been extended from objects of attention to attributes, known as the second-level (McCombs, 1992; McCombs and Shaw, 1993; McCombs et al., 2014). From the second-level, it became apparent that “the media not only can be successful in telling us what to think about, they also can be successful in telling us how to think about it” (McCombs, 2005, p.546, emphasis in original). In the early 2010’s, the theory extended with a third-level (Guo et al., 2012; Guo and McCombs, 2011). This level includes a network component to the theory. In this chapter, we will describe the state-of-the-art of agenda-setting theory for the coverage of politics, and especially policies and political issues in media in three trends. Thereafter, we discuss the most common used research designs (pp.5–8), and we conclude with the limitations and possible future directions of the field (pp.8–10)

This chapter provides an overview about common methodological designs and constructs employed to examine the contents of health coverage and points out current research desiderata.

Media systems have changed significantly as a result of the development of information technologies. However, typologies of media systems that incorporate aspects of digitalization are rare. This study fills this gap by identifying, operationalizing, and measuring indicators of media systems in the digital age. We build on previous work, extend it with new indicators that reflect changing conditions (such as online news use), and include media freedom indicators. We include 30 countries in our study and use cluster analysis to identify three clusters of media systems. Two of these clusters correspond to the media system models described by Hallin and Mancini, namely the democratic-corporatist and the polarized-pluralist model. However, the liberal model as described by Hallin and Mancini has vanished; instead, we find empirical evidence of a new cluster that we call “hybrid”: it is positioned in between the poles of the media-supportive democratic-corporatist and the polarized-pluralist clusters.

This chapter studies rally-around-the-flag effects cross-nationally during the COVID-19 crisis, with a focus on the moderating role of media and political polarization. It relies on a comparative two-wave panel survey scoping across 17 countries to measure changes in trust in government before and after the outbreak of the pandemic and levels of media and political polarization. It finds that although rally effects are modest and vary across countries, the COVID-19 crisis on average increased trust in government cross-nationally. However, high initial levels of media polarization and increasing polarization between wave 1 and wave 2 systematically reduced rally effects. In contrast, where media polarization was low and political polarization did not increase before and after the outbreak of the pandemic, governments were much more able to capitalize on the crisis to increase their level of public support. The findings suggest a different logic for the moderating role of media and political polarization, which is discussed in the closing section. The chapter also discusses the implications of the findings for declining levels of trust in government, government capacity, and the handling of future crises.

El treball que es presenta en aquesta tesi pretén contribuir al camp de la ciència de superfícies biològiques, amb el desenvolupament de superfícies adaptades amb cadenes lateral reactives per tal de unir covalentment biomolècul·les d'interès a la superfície.La polimerització assistida per plasma del recobriments actius és un mètode atractiu per tal d'obtenir cadenes laterals reactives, mitjançant pel·lícules nanomètriques amb densitats de grups funcionals adaptats.

La part essencial del treball es dirigeix cap al funcionalització amb grups èster de pentafluorofenil a la superfície, durant la polimerització per grafting i polimerització de plasma pulsat de pentafluofenil metacrilat. Aquesta classe de grup làbil és de gran interès per a la seva fàcil reactivitat amb molècules amb mines terminals, com pèptids. Altres monòmers comercials també s'han emprat al començament de l'estudi, com a primera aproximació a les tècniques de plasma. La caracterització d'aquestes superfícies s'ha fet a través de tècniques analítiques com FTIR, XPS, AFM o ToF - SIMS entre d'altres.A més, s'ha dut a terme un estudi per fer a mida el polímer de PFM per a millorar la retenció de la seva estructura, i així com un estudi profund de la seva reactivitat davant de molècules amb amines terminals diferents d'interès, afegint SPR o l'aplicació de sensors microcantiliver a les tècniques de caracterització per aconseguir una millor comprensió de la química i cinètica de la reacció.Sobre el propòsit d'aconseguir superfícies funcionalitzades útils, s'ha realitzat un patterning de les superfícies amb l'ús de màscares per a capa selectiva de les mostres per controlar les àrees modificades. Això s'ha fet per a l'aplicació d'aquesta pel·lícula a dispositius reals, així com a prova de la seva biocompatibilitat per cultiu cel·lular i per assaigs in vivo., El trabajo que se presenta en esta tesis pretende contribuir al campo de la ciencia de superficies biológicas, con el desarrollo de superficies adaptadas con cadenas lateral reactivas con el fin de unir covalentemente biomoléculas de interés a la superficie.La polimerización asistida por plasma de recubrimientos activos es un método atractivo con el fin de obtener cadenas laterales reactivas, mediante películas nanométricas con densidades de grupos funcionales adaptados.

Plasma polymerization of surface active coatings is an attractive method to obtain reactive side chains, by making nanometer thick films of tailored functional group densities. By controlling the experimental conditions, the structure of the polymer deposit can be largely controlled and the chemical structures obtained can range from highly functional polymer networks of low cross link density to polymer networks of low functional group but high cross link densities. The research described in this thesis deals with the surface modification of various substrates by plasma polymerization. The major part of the work is directed towards the funtionalization with pentafluorophenyl ester groups on the surface, through the grafting polymerization and pulsed plasma polymerization of pentafluophenyl methacrylate. This kind of labile group is of high interest for its easy reactivity to amino terminated molecules, such as peptides. Other commercial monomers were also used at the beginning of the study, as a first approach to the plasma techniques. The characterization of these surfaces is done through several analytical techniques as FTIR, XPS, AFM or ToF-SIMS among others. Furthermore, a study for tailoring the PFM polymer for better structure retention and deep study of its reactivity in front of different amino terminated molecules of interest was performed, adding SPR or the implementation of microcantilever sensors to the characterization techniques to achieve a better understanding of the chemistry and kinetic of the reaction, in order to achieve the best peptide binding for reliable well characterized bioactive interface..On the aim of achieving useful functionalized surfaces, a patterning of the surfaces with the use of masks for selective coating of the samples has been performed to control the modified areas. This has been done for application of this film to real devices, as well as to test of its biocompatibility by cell culture and in vivo assays.
