Optical nanoantennas are of great importance for photonic devices and spectroscopy due to their capability of squeezing light at the nanoscale and enhancing light–matter interactions. Among them, ...nanoantennas made of polar crystals supporting phonon polaritons (phononic nanoantennas) exhibit the highest quality factors. This is due to the low optical losses inherent in these materials, which, however, hinder the spectral tuning of the nanoantennas due to their dielectric nature. Here, active and passive tuning of ultranarrow resonances in phononic nanoantennas is realized over a wide spectral range (≈35 cm−1, being the resonance linewidth ≈9 cm−1), monitored by near‐field nanoscopy. To do that, the local environment of a single nanoantenna made of hexagonal boron nitride is modified by placing it on different polar substrates, such as quartz and 4H‐silicon carbide, or covering it with layers of a high‐refractive‐index van der Waals crystal (WSe2). Importantly, active tuning of the nanoantenna polaritonic resonances is demonstrated by placing it on top of a gated graphene monolayer in which the Fermi energy is varied. This work presents the realization of tunable polaritonic nanoantennas with ultranarrow resonances, which can find applications in active nanooptics and (bio)sensing.
Near‐field nanoscopy monitors active and passive tuning of ultranarrow resonances in phononic nanoantennas over a wide spectral range (−35 cm−1, being the resonance linewidth ≈9 cm−1). Passive tunability can be realized by tailoring the dielectric environment of nanoantennas made of boron nitride, while reversible in situ tuning of narrow resonances is realized by placing nanoantennas on top of a graphene layer.
This study analyses the information and tools for citizen participation on the institutional websites of local bodies to improve participation in the management of local resources in a context ...following the introduction of Spain’s Transparency Law. The method is based on applying 14 indicators to analyse the institutional websites of 605 municipalities that have over 10,000 residents, located in 9 autonomous communities of the Spanish state. The main results show how the institutional information offered on the websites of the councils analysed does not follow journalistic criteria in terms of accountability, meaning that citizens’ decisions regarding their local governments cannot be based on precise, reliable information. In this regard, in this study we have confirmed that council websites publish very little information on the activity of the opposition or on the plenary sessions, debates and agreements, but do publish information on the activity of the government. Furthermore, they do not make use of web resources for citizen participation, which impedes the transparent, collaborative management of political processes between leaders and citizens. Nonetheless, the results show how political and technical managers are not averse to change if they have access to guidance and incentives to improve the management of information and participation on municipal websites.

The fact that traditional radio is synchronous and unidirectional, with little or no room for interaction and content selection, is one of the main reasons why young people have turned their backs on ...it. In retrospect, conventional radio never cared for the younger generation, never designing strategies to bring them in. As a result, radio lost its relevance and it does not feature as part of young people’s digital diet. Over the last year, the number of podcast consumers has steadily increased, which is causing this format to become more and more cemented in society. It could be a way to gain younger listeners, an opportunity not to be missed by the radio industry. In the past, young people continued to listen to the radio as they got older, but that is no longer the case nor is radio seen as the go-to resource for new musical content. The challenge for radio is clear: regaining its influence through proposals with added value to differentiate itself from global platforms. In order to carry out this research, a total of 410 young university students were surveyed. The results show what the current picture is in such a changing atmosphere. It has been observed that this audience bases their audio consumption on personal preferences, they mainly access it via social media and they would find it useful and interesting to create their own podcast. This paper includes a podcast where academic experts and audio professionals, interviewed for the doctoral thesis “xxx (anonymity for review)”, reflect on the strategies that radio should adopt in order to gain young listeners.
In recent years, the current media ecosystem has been transformed owing to the adaptation to digital media, affecting all genres and audiovisual formats. As a result, from the point of view of ...participation, the viewer-user has acquired an unprecedented protagonism owing to the possibility now offered by social networks. The informative genre, far from turning its back on this reality, has allied itself with it and is exploring new ways of reaching audiences, and one of the latest trends has to do with informative television channels and the use of Instagram reels. This research focuses on the case of RTVE Noticias (@rtvenoticias), with the purpose of analyzing the use and communication strategy that they make of Instagram reels on this platform, precisely because it is the feature that has achieved more popularity of late. The findings show that RTVE Noticias does not currently have a clear strategy when it comes to informing through this medium, which translates into content being reused from other media without really taking advantage of the narrative potential of the network, resulting in low interaction with followers. The main results obtained allow us to continue a rich academic debate related to the media’s use of social networks from the perspective of information and consumption, mainly among the youngest users.
This article analyses the differences in the level of transparency and quality of information on the institutional websites of Spanish councils depending on whether the mayor’s office is held by a ...woman or a man. We focus on 605 Spanish municipalities with more than 10,000 inhabitants in which women mayors represent 26.3% (n = 159) of the total. The method is based on 52 quantitative indicators divided into two thematic blocks related to municipal transparency and to information for participation. The principal results reveal that municipalities led by women yield better results in terms of compliance with the indicators evaluated, with 50.68%, compared to the municipalities in which the mayor is a man, with 38.13%. In addition, a more detailed analysis reveals how women mayors obtain better results in all groups of indicators: transparency, quality of the information published on municipal websites and tools provided for citizen participation. The study reveals how the increase in elected women has a positive influence on the implementation of policies that allow for more transparent information and communication and that promote greater inclusion of citizens in the public debate.
The front pages of newspapers are the main showcase to sell the product. Those first pages are a perfect hook for newspapers to attract readers; thus, it becomes vital to show striking pieces of ...information, captivating the audience. In the case of the written sport press in Spain, there is a key period in which true information is mingled with half-truths and even rumors: The summer transfer window. This paper shows an analysis of the front-page news appearing in the Spanish sports newspapers Marca, As, Mundo Deportivo, and Sport, over a five-year period (2015–2019), based on a sample of 120 different issues of the newspaper. Many times, the media present information either as something true or as a hypothesis or possibility. After quantitatively analyzing that, it can be noticed that in more than 50% of the cases, the signing or sale of the player referenced on the front page (the main news) does not occur. Similarly, it can be observed that there is a direct link connecting the news referring to Real Madrid with Marca and As, and Fútbol Club Barcelona with Mundo Deportivo and Sport. Finally, almost 100% of this news is showed along with real photographs, using photo montage in just a few cases.
La rendición de cuentas de los medios de comunicación constituye en un mecanismo de transparencia y proximidad con las audiencias para avanzar hacia la participación, pluralidad y diversidad, se ...sustenta en la ética y se complementa con normas para procurar modelos de corregulación. La presente investigación toma la tipología de instrumentos propuesta en el proyecto MediaACES para establecer la percepción de los periodistas y los ciudadanos ecuatorianos sobre los instrumentos de rendición de cuentas impulsados de forma interna y externa a los medios de comunicación social. El análisis es de tipo descriptivo y relacional, se emplea metodología cualitativa y cuantitativa a través de encuestas y un foro de discusión virtual. Los instrumentos de rendición de cuentas más apreciados son los tradicionales externos a las empresas de medios tanto en autorregulación, participación y transparencia, se aprecia la intención de emplear aquellos mecanismos de amplio conocimiento a través de los cuales los medios pueden mostrar sus buenas prácticas, se evidencia además una fuerte impregnación de la Ley de Participación respecto a la rendición de cuentas, se la concibe como un deber legal, en ello influye lo sucedido con la Superintendencia de Comunicación durante el gobierno del presidente Rafael Correa.
