Topic Model Validation Methods and their Impact on Model Selection and Evaluation
No full textTopic Modeling is currently one of the most widely employed unsupervised text-as-data techniques in the field of communication science. While researchers increasingly recognize the importance of validating topic models and given the prevalence of discussions of inadequate validation practices in the literature, there is limited understanding of the consequences of employing different validation strategies when evaluating topic models. This study applies two different methods for topic modeling to the same text corpus. It uses four validation strategies to assess how the choice of validation method affects the final model selection and evaluation. Our findings indicate that different approaches and methods lead to different model choices and evaluations, which is problematic. This might lead to unwanted results in case the choice of model has a decisive impact on findings and, consequently, on theory development and practical implications
Cross-Platform Information Flow and Multilingual Text Analysis: A Comparative Study of Weibo and Twitter Through Deep Learning
No full textThis study delved into cross-platform information flow and multilingual text analysis by examining social media posts on Weibo and Twitter in Chinese and English. We investigated public opinions about a violent restaurant attack in China that received widespread attention and validated three strategies of Bidirectional Encoder Representations from Transformers (BERT) to classify multilingual social media posts regarding their attitudes, targets, and frames. This study found that there was more criticism than support on Twitter than on Weibo when calling for social justice. When targeting the governments, Weibo users focused more on the local level, while Twitter users focused more on the state level. When framing their opinions, Weibo users focused more on gender violence, while Twitter users focused more on gang violence. These variations within social media posts across platforms were fundamentally influenced by the interruption of transnational information flow as a result of Chinese governance and censorship of the internet. Through the “porous censorship,” social media users’ autonomy and trust in the government played critical roles in the dynamics between online criticism and authoritarian responsiveness
Are we projecting gender biases to ungendered things? Differences in referring to female versus male named hurricanes in 33 years of news coverage
No full textHurricanes are ungendered phenomena that are ascribed with gendered names. We examined if news information about the hurricanes are presented using gendered language. This work helps identify if people use gender stereotyping when referring to gender-neutral entities, and what these stereotypes might be. We use methods from natural language processing, qualitative text analysis, and statistics to analyze how gender is expressed in disaster-related news via text-level indicators: (1) pronouns, (2) lexical, syntactic, and semantic features of words related to hurricanes, and (3) types of sources quoted. Our sample contains news articles on 47 hurricane events from 1979 to 2012 from two weeks before to two weeks after landfall. We find that: (1) hurricanes are mainly referred to by gender-neutral pronouns, however, (2) when gendered pronouns are used, female-named hurricanes are five times more likely to be referred to by a gendered pronoun than male-named hurricanes, (3) adjectives and verbs used in discussing female-named hurricanes are on average more negative than those used for reporting on male-named-hurricanes, and (4) governmental sources are most frequently quoted as authority voices (voices from citizens and non-governmental entities are catching up), and a majority of these voices do not directly mention hurricanes with gendered references
Poetesse in accademia: il caso delle sorelle Bonanno tra gli Accesi di Palermo
No full textIl contributo analizza i sonetti di tre poetesse palermitane: Marta, Laura e Onofria Bonanno. I componimenti furono pubblicati all’interno del primo volume delle Rime dell’Accademia degli Accesi di Palermo nel 1571. Pur occupando uno spazio marginale nella raccolta, le poetesse si inseriscono a pieno titolo nello scambio di socievole conversazione attivato dalle rime di corrispondenza in stile petrarchista, dialogando con i principali membri dell’Accademia e rappresentando per essi un modello di femminilità virtuosa. La lode del cenacolo degli Accesi e il motivo spirituale ricorrono nei sonetti delle poetesse palermitane, caratterizzandosi come cifra stilistica e tematica della loro produzione poetica.

The paper analyses the sonnets of three female poets from Palermo: Marta, Laura and Onofria Bonanno. The poems were published in the first volume of the Rime edited by the Accesi Academy of Palermo in 1571. While occupying a marginal space in the collection, the poets fully participate in the sociable exchange, communicating with the main members of the Academy and representing a model of virtuous femininity. The praise of the cenacle of the Accesi and the spiritual motifs are the mains topics of the sonnets and key themes of these poets’ work
Television archives, social networks and the young audiences: The example of Internet memes as a way to revitalise public broadcasters’ engagement
Get PDFThe purpose of this research is to explore the efforts that Spanish public television archives are making to bring their audiovisual content closer to young people via social networks. Specifically, this text focuses on analysing the public television archives of the Spanish national television company RTVE and of the Andalusian regional public television agency (RTVA), known as Archivo RTVE and MemorANDA, respectively. The methodology used is based on both qualitative and quantitative tools, consisting of content analysis and in-depth interviews. The results obtained show that both platforms manage to reach young people, but indirectly through viral videos or Internet memes. The RTVE archive is the most successful among young people because it has a more extensive collection and more resources as well as a policy that is more clearly geared towards the dissemination of its audiovisual heritage. The most negative aspect identified in this study was the repetition of regional clichés, especially in the case of MemorANDA
Marlis Prinzing & Roger Blum (Hrsg.). Handbuch Politischer Journalismus
Get PDFMarlis Prinzing und Roger Blum haben das «Handbuch Politischer Journalismus» herausgegeben, weil es bisher keine vergleichbare Publikation gab, obwohl der politische Journalismus ein zentrales Feld der Berichterstattung ist. Das Handbuch versteht sich als Brücke zwischen aktueller Forschung und Praxis. Es enthält Beiträge aus unterschiedlichen Disziplinen und gibt länderübergreifende Einblicke in die vielfältigen Arbeitsfelder des politischen Journalismus – mit Schwerpunkten auf Deutschland, Österreich und der Schweiz. Diese Zusammenführung unterschiedlicher Perspektiven verdeutlicht den integrativen Anspruch des 900 Seiten starken Werks. Es hat sich zum Ziel gesetzt, «den politischen Journalismus in modernen […] europäischen […] Demokratien einmal gesamthaft darzustellen» (S. 17). Dies war, wie Prinzing und Blum in ihrer Einleitung einräumen, ein arbeitsintensives Unterfangen, das sich aber – wie der Erfolg zeigt – gelohnt hat. Das Handbuch gewinnt sein Publikum in der Medien- und Kommunikationswissenschaft, in der Medienpraxis und Politik, in der PR- und Öffentlichkeitsarbeit sowie in der Verwaltung und den Staatskanzleien. Der Erfolg gründet in verschiedenen Stärken des Buches
Online Health Communities in Controversy over ME/CFS and Long Covid
No full textThe condition known variously as myalgic encephalomyelitis, chronic fatigue syndrome, or ME/CFS has been steeped in controversy for 40 years or more. Long Covid, first noticed and named in 2020, has become entangled with the ME/CFS controversy because of striking similarities in the experiences of patients suffering from the two illnesses. Online health communities (OHCs) have played central roles in both controversies, but these are not the kinds of roles that have been so well-documented in prior literature. While prior research has established many ways in which participation in an OHC may benefit or otherwise affect community members themselves, this essay focuses on how OHCs contribute to positional shifts in health controversies that involve other communities as well. Using a framework for understanding health controversies as argumentative polylogues, I show that OHCs arguing with other players have made contributions that are both effective in gaining ground for the OHCs\u27 own goals and in elevating the overall quality of the debate. Further, in some cases these contributions have been so innovative as to suggest surprising future trajectories for OHCs
Vergessen dürfen? Erinnern müssen? Die Grosse Kammer des EGMR zum Recht auf Vergessenwerden - 57292/16 (Hurbain gegen Belgien) vom 4. Juli 2023
No full textDas «Recht auf Vergessenwerden» umfasst dem Grunde nach den persönlichkeitsrechtlich geprägten Anspruch eines Individuums, öffentlich einsehbare Informationen unter bestimmten Voraussetzungen löschen, berichtigen oder anonymisieren zu lassen. Ausgehend von Art. 8 EMRK haben die Konzeption als solche ebenso wie die notwendigen Voraussetzungen in den vergangenen Jahren jedoch zahlreiche Konkretisierungen erfahren. Anlässlich des Urteils der Grossen Kammer des EGMR (57292/16, Hurbain gegen Belgien) vom 4. Juli 2023, in dem der Gerichtshof die Voraussetzungen für die Bejahung des Anspruchs festigt und weiter ausbaut, fasst der Beitrag die bisherige Entwicklung des Rechts auf Vergessenwerden zusammen, analysiert das aktuelle Urteil und setzt sich u.a. mit möglichen Auswirkungen auf die Pressefreiheit auseinander. Er schliesst mit einem Fazit und Ausblick.

En principe, le «droit à l\u27oubli» comprend le droit d\u27un individu, fondé sur le droit de la personnalité, à ce que certaines informations rendues accessibles au public soient - sous certaines conditions - effacées, rectifiées ou anonymisées. La notion de «droit à l\u27oubli», basé sur l\u27art. 8 CEDH, et ses conditions d\u27application ont fait l\u27objet de nombreuses concrétisations jurisprudentielles ces dernières années. La présente contribution retrace l\u27histoire du «droit à l\u27oubli» et, à l\u27occasion de l\u27arrêt de la Grande Chambre de la CEDH (57292/16, Hurbain c. Belgique) du 4 juillet 2023 - dans lequel la Cour renforce et élargit les conditions d\u27exercice de ce droit-, examine, entre autres, les potentielles répercussions sur la liberté de la presse. L\u27auteur conclut en esquissant de nouvelles pistes de réflexion
Die Kunst der Kritik: Der Einkaufswagen bei Banksy
Get PDFDa kein Abstract des Artikels vorhanden ist, finden Sie hier den Beginn des Artikels:
Graffiti-Mäuse in der Londoner U-Bahn, kunstvolle Parodien öffentlicher Figuren und zahlreiche Affen in unterschiedlichsten Situationen gehören zu der breiten Sammlung von Werken des anonymen, britischen Künstlers Banksy. Seine politisch aufgeladene Kunst und der Widererkennungswert in seinem klassischen Stencil Style machen ihn zu einem der bekanntesten Strassenkünstler*innen aller Zeiten. Durch ortspezifische Inszenierungen politischer Motive übt er einen subversiven, antikapitalistischen und politischen Aktivismus aus. Ein Beispiel für die Bedeutung seiner Ortswahl ist seine Strassenkunst an der Trennmauer zwischen Israel und Palästina. Auch die Wahl seiner Motive, beispielsweise ein Mädchen, welches eine Bombe umarmt, hilft ihm seine politische Kritik offensichtlich auszuüben
