Abstract Inferring the nature of disorder in the media where elastic objects are nucleated is of crucial importance for many applications but remains a challenging basic-science problem. Here we propose a method to discern whether weak-point or strong-correlated disorder dominates based on characterizing the distribution of the interaction forces between objects mapped in large fields-of-view. We illustrate our proposal with the case-study system of vortex structures nucleated in type-II superconductors with different pinning landscapes. Interaction force distributions are computed from individual vortex positions imaged in thousands-vortices fields-of-view in a two-orders-of-magnitude-wide vortex-density range. Vortex structures nucleated in point-disordered media present Gaussian distributions of the interaction force components. In contrast, if the media have dilute and randomly-distributed correlated disorder, these distributions present non-Gaussian algebraically-decaying tails for large force magnitudes. We propose that detecting this deviation from the Gaussian behavior is a fingerprint of strong disorder, in our case originated from a dilute distribution of correlated pinning centers.

The territorial image is formed both purposefully by the subjects of image-making, and spontaneously-based on the influence of information content published in various media. The purpose of the research is to analyze the image of the Republic of Mordovia in the information space of the Volga Federal district. The image of the territory formed by external target audiences by means of news materials is studied using the method of case study and content analysis of publications: “Volga news”, “Federal Press” news of the PFD, “Pravda PFD”. The authors conclude that modern reality is perceived through the prism of the information field created by mass media. The media creates images filled with certain data, facts, colored by emotions, on the basis of which representations, opinions, judgments, and assessments are subsequently formed. The media play a significant role in shaping the territorial image, especially for external target audiences who are not familiar with the region and do not have their own assessment knowledge and experience. Most of the information content about the Republic in the studied media is related to the main thematic blocks: politics, economy, social sphere, culture (art, sports). Moreover, if in the publications “Volga news” and “Pravda PFD” mention of the region prevails in the economic block, then in the publications “Federal Press” and “Nezavisimaya Gazeta” - in the political one. The Volga news publication significantly dominates the rest in terms of the number of publications about Mordovia. The content of publications is mostly positive and neutral related to the issues of economic development of the territory and the preparation and holding of the world football championship. Pravda PFD mentions the Republic in the context of news from neighboring territories, most of the publications date back to 2018, but here the context is related to the Republic's positions among the regions of the PFD in various ratings. The publication “Federal-Press” forms a generally reflective image of the territory, focusing on the negative aspects of regional life. “Nezavisimaya Gazeta”, giving priority to political news, maintains a neutral and reflective context of publications, paying attention to the key problems of the territory. Thus, the desired image of the region is counter-dictated to the image broadcast by the media through various information channels, so it is necessary to constantly monitor the information space and timely correction of the broadcast materials.

Freedom of speech is not freedom from ethics: the 2019 Israel Folau media controversy as a case study

This article examines how freedom of speech is framed in the media controversy surrounding the Australian rugby player Israel Folau’s April 2019 Instagram post. A content analysis and framing analysis of newspaper reportage reveals that the controversy has been largely discussed in terms of whether or not Folau’s speech was being curtailed and whether this curtailing indicates a broader, ideologically motivated censoriousness. This discussion is problematic in that it says little about the actual substance of Folau’s post. This article argues that debates surrounding freedom of speech such as the one involving Folau could and should be enriched by an engagement with ethical principles. This engagement is premised on a commitment to the free exchange of views, while acknowledging that ‘speech’ is not always inherently beneficial for democracy, nor worth defending.

This study investigated the resilience of the Chinese child protection system in responding to the special needs of children in difficulty under the specific circumstances caused by the COVID-19 pandemic. This study applied qualitative document analysis of child protection administrative documents, in-depth interviews with 13 child protection professionals, and an in-depth case study of 14 children living in difficulty, complemented by relevant information available in the media. The results indicate that there are good policies in China’s child protection services but the organizational and functional fragmentation complicates implementation, suggesting a need for the development of bottom-up practices. The essential conclusion supported by these results is that the child protection system should be regarded and developed as a systematic project combining the legal, policymaking, and professional systems of child welfare services as well as governmental and non-governmental forces. As the COVID-19 pandemic has raised awareness of the need to develop the field of child protection holistically as an integrated system in terms of social sustainability in China, an international literature-based comparison indicates that the pandemic has also raised similar political awareness in other countries.

AbstractThe task of fault detection is crucial in modern chemical industries for improved product quality and process safety. In this regard, data-driven fault detection (FD) strategy based on independent component analysis (ICA) has gained attention since it improves monitoring by capturing non-gaussian features in the process data. However, presence of measurement noise in the process data degrades performance of the FD strategy since the noise masks important information. To enhance the monitoring under noisy environment, wavelet-based multi-scale filtering is integrated with the ICA model to yield a novel multi-scale Independent component analysis (MSICA) FD strategy. One of the challenges in multi-scale ICA modeling is to choose the optimum decomposition depth. A novel scheme based on ICA model parameter estimation at each depth is proposed in this paper to achieve this. The effectiveness of the proposed MSICA-based FD strategy is illustrated through three case studies, namely: dynamic multi-variate process, quadruple tank process and distillation column process. In each case study, the performance of the MSICA FD strategy is assessed for different noise levels by comparing it with the conventional FD strategies. The results indicate that the proposed MSICA FD strategy can enhance performance for higher levels of noise in the data since multi-scale wavelet-based filtering is able to de-noise and capture efficient information from noisy process data.

The Olympic Games

The Paralympic Games are one of the world’s most important multisport events, maybe second only to the Olympic Games. However, research conducted to date shows that the media do not devote as much space to them as would accordingly be expected. This article proposes, through a case study, a new way of approaching this hypothetical discrimination by comparing the attention that the London Paralympic Games received from the Spanish print press with the attention that other sports received (football, basketball, tennis, cycling, motor sports and other minority sports) while those Games were being held. The main finding of our study is that over the period analysed, the Spanish press devoted less space to the Paralympic Games than to any other sport.

This study aims to analyse the media management strategy of Indonesian television stations during the Covid-19 pandemic. In March 2020, an outbreak of the Covid-19 pandemic in Indonesia affected the operations of broadcasting offices, which forced people to work from home. This situation affects the operations, strategy, and content of the television industry. The object of research is Kompas TV, one of the largest media companies in Indonesia, which was the first to implement a digital concept for its customers. The concepts of planning, organising, actuating, and controlling are used to analyse the strategies media utilised. The methodology employed for the current research takes the form of a case study by adopting the qualitative approach through an in-depth interview and observation. The results showed that Kompas TV, through its digital platform in the form of websites, YouTube channels, and social media, achieved an increase in the number of viewers, users, and engagement during the pandemic. In particular, the digital aspect does not only appear in communication, but also in the implementation of the Kompas TV strategy. The results of the study also revealed that strategies carried out on Kompas TV can be used as a model for other television in Indonesia to emulate, in order to sustain its business in times of crisis. Keywords: Strategy, broadcast management, Indonesia television station, pandemic Covid-19, qualitative research.
