Adiabatic versus Non-Adiabatic Electron Transfer at 2D Electrode Materials

2021

<div><div><div><p>Outer-sphere electron transfer (OS-ET) is a cornerstone elementary electrochemical reaction, yet microscopic understanding is largely based on idealized theories, developed in isolation from experiments that themselves are often close to the kinetic (diffusion) limit. Focusing on graphene as-grown on a copper substrate as a model 2D material/metal-supported electrode system, this study resolves the key electronic interactions in OS-ET, and identifies the role of graphene in modulating the electronic properties of the electrode/electrolyte interface. An integrated experimental-theoretical approach combining co-located multi-microscopy, centered on sc…

The image of the candidates in the 2019 General Elections in Spain

2019

[Resumen] Las Elecciones Generales de 1977 en España obligaron a los partidos a explicar cuestiones elementales como “qué significaba votar”. En general, la imagen proyectada de los candidatos era una cuestión “menor”, dada la falta de cultura democrática del momento. Tras 42 años desde la transición, el contexto político y comunicativo ha dado un vuelco que exige de una aproximación más compleja. Los partidos políticos son conscientes de la importancia que tiene construir la imagen pública de sus candidatos. En este trabajo analizamos la imagen del principal cartel de campaña de los candidatos a presidente en las Elecciones Generales de abril de 2019 de Vox, PP, C’s, PSOE, UP y del candida…

How, Why and with Whom Do Local Politicians Engage on Facebook?

2013

Part 2: Social Media and E-Participation; International audience; This article focuses on how, why and with whom local politicians engage on Facebook. Based on a literature review of the public sphere, eParticipation and research related to social media, we propose a theoretical framework that identifies thematic areas integral to understanding the nature of political participation. The explanatory potential of our ‘ENGAGE’ model (Exchange, Narcissist, Gather, Accented, General and Expense) is exemplified by conducting a qualitative case study focusing on politicians in a local municipality in southern Norway. The findings indicate various uses of Facebook among the respondents, and a disso…

Historia y Enseñanza de la Astronomía : II. La posición de los cuerpos celestes

2006

In the following pages we continue the study of an ensamble of astronomical instruments utilized from early times, which still help us to complete an elementary knowledge of the position of the objects constituting the celestial sphere and their motions. Special emphasis has been given to their pedagogical implications.

Social Media as Public Sphere: A Stakeholder Perspective

2016

Purpose This paper aims to examine major stakeholders’ communication preferences in eParticipation initiatives and discuss how this affects the public sphere. Despite the potential of social media, it has proven difficult to get people actively involved in the decision-making processes. There is a need for more research on how stakeholders manage and use social media to communicate. Design/methodology/approach The study was conducted as a qualitative case study. Data sources include interviews, social media content, document analysis and field notes. Findings Communication preferences of stakeholders vary according to their salience level. Stakeholders with higher salience are less likely …

Madagascar's independence jubilee: a nation's holiday in times of crisis

2013

The fiftieth anniversary of Madagascar's independence in 2010 took place in the midst of political crisis. The transitory government staged large public parties to mark the Jubilee. Despite a public discussion about legitimacy and justification of this fact, the national holiday was lavishly celebrated. In Madagascar, Independence Day is also an important family event and emphasis was put on private celebrations including family feasts and reunions. As a result, it enhanced the participants' emotional attachment to their personal and local face-to-face milieu. This article asks how the golden jubilee was celebrated against a backdrop of political illegitimacy. I contrast official state-led …

Zarys koncepcji Habermasowskiej sfery publicznej

2015

Dla Habermasa sfera publiczna jest centrum życia społeczno-politycznego. Jest ona niejako buforem między społeczeństwem a płaszczyzną władzy i polityki. Właściwy jej kształt zapewnia możliwość trafnej oceny problemów i przekazywania ich do centrów decyzyjnych władzy. Sfera publiczna jest sferą prywatnych ludzi gromadzących się w publiczność, jednak nie jako biernych widzów, ale aktywnie włączających się w definiowanie i rozwiązywanie wspólnie tematyzowanych problemów. Jej ideał Habermas upatruje w XVIII-wiecznej sferze mieszczańsko-obywatelskiej, po której jednak następuje jej rozpad. Media stają się elementem opiniotwórczym i manipulującym publicznością.

Physical Activity and Exercise: Text Mining Analysis

2021

It is currently difficult to have a global state of the art vision of certain scientific topics. In the field of physical activity (PA) and exercise, this is due to information overload. The present study aims to provide a solution by analysing a large mass of scientific articles using text mining (TM). The purpose was to analyse what is being investigated in the PA health field on young people from primary, secondary and higher education. Titles and abstracts published in the Web of Science (WOS) database were analysed using TM on 24 November 2020, and after removing duplicates, 85,368 remained. The results show 9960 (unique) words and the most frequently used bi-grams and tri-grams. A co-…
