Assorted Spatial Optical Dynamics of a Generalized Fractional Quadruple Nematic Liquid Crystal System in Non-Local Media

Nematicons upgrade the recognition of light localization in the reorientation of non-local media. the current research employs a powerful integral scheme using a different procedure, namely, the modified simple equation method (MSEM), to analyze nematicons in liquid crystals from the controlling model. The expanded MSEM is investigated to enlarge the applicability of the standard one. The suggested expansion depends on merging the MSEM and the ansatz method. The new generalized nonlinear n-times quadruple power law is included. With the aid of the symbolic computational package Mathematica, new explicit complex hyperbolic, periodic, and more exact spatial soliton solutions are derived. Moreover, the related existence constraints are obtained. To show the dynamical properties of some of the obtained nematicons, three-dimensional profiles with corresponding contours are depicted with the choice of appropriate values of arbitrary parameters. The fractional impacts in various applicable senses are analyzed to investigate the generality of the considered model.

Sentiment Analysis Based on Transformer

This article aims to explore the sentiment analysis of Transformer comments on Weibo to understand the attitudes and emotional tendencies of social media users regarding the movie The boy and the heron. This paper uses natural language processing technology and sentiment analysis model Transformer to crawl the Weibo comment data set, analyzes the anti-crawling mechanism of Weibo, adds HEADERS and REFERER directly in the code to bypass the inspection, and preprocesses it. Sentiment analysis was conducted on a large number of Weibo comments related to the boy and the heron. The results of the study showed that the vast majority of the comments expressed positive emotional attitudes and held positive and appreciative attitudes towards the boy and the heron. This study reveals that social media users have positive attitudes and emotional identification with the boy and the heron, and the audience really likes the film, which is of great help for the filmmakers to further understand the advantages and disadvantages of the film. Performing Weibo sentiment analysis based on advanced natural language processing technologies such as transformers can not only improve the accuracy and efficiency of sentiment analysis, but also help promote the progress and application of artificial intelligence technology. This is important for the development of more intelligent social media analysis tools and systems.

Development of Pidgin English Hate Speech Classification System for Social Media

With the widespread use of social media, people from all walks of life—individuals, friends, family, public and private organizations, business communities, states, and entire nations—are exchanging information in various formats, including text, messages, audio, video, cartons, and pictures. Social media also facilitates the distribution and propagation of hate speech, despite the immense benefits of knowledge sharing through these platforms. The purpose of this work was to construct a text-based, Pidgin English hate speech classification system (HSCS) in social media, taking into account the alarming rate at which hate speech is shared and propagated on social media, as well as the negative effects of hate speech on society. We used text data sets in Pidgin English that were taken from Twitter and Facebook (3,153). To train the Support Vector Machine (SVM) text classifier to identify hate speech in Pidgin English, 70% of the Pidgin English data set was annotated. The SVM classifier's performance was tested and assessed using the remaining thirty percent of the Pidgin English text data set. The test set findings' confusion matrix, as determined by the HSCS performance evaluation, was 62.04%, 64.42%, 0.7541, 0.6947, and 0.64 in terms of accuracy, precision, recall, F1-score, and Receiver Operating Characteristics (ROC) curve. When HSCS was compared to other Machine Learning (ML) classifiers, such as Logistic Regression (LR), Random Forest (RF), and Naive Bayes, the results showed that LR had accuracy and precision of 61.51% and 63.89%, RF had 54.88% and 50.65%, and Naive Bayes had 61.51% and 63.89%.

Cladding-free Fermi arc surface states and topological directional couplers in ideal photonic Weyl metamaterials

Photons can freely propagate in a vacuum, making it not a simple insulator but rather a conductor for photons. Consequently, in topological photonics, domain wall structures with opposing effective mass terms are used as cladding to confine electromagnetic waves. This approach is necessary to demonstrate topological edge/surface waves and Fermi arc surface states (FASS). Here, we show that the cladding-free FASS with high field localization at the boundary can be achieved using ideal Weyl gyromagnetic metamaterials (GMs). In these GMs, the ideal Weyl semimetal phase exists due to the dispersionless longitudinal modes. At the boundary of the GMs-vacuum system, the cladding-free FASS connects the projections of Weyl nodes with opposite chirality, thanks to the bulk-boundary correspondence principle. We further confirm that chiral boundary modes can propagate without experiencing scattering or backward reflection, i.e., they can advance seamlessly approximately various types of defects. Remarkably, various types of topological directional couplers are achieved by utilizing cladding-free FASS in an ideal gyromagnetic medium. Our theoretical analysis reveals that the underlying operational principle for accomplishing these nonreflecting directional couplers is due to the single coupling channel between the cladding-free FASS and the multi-type scatterers of the continuous media. Furthermore, the controllable propagation and topological directional coupling of cladding-free FASS can be further explored by adjusting the ideal gyromagnetic medium and boundary configurations of the continuous media system. This research offers increased flexibility for the development of cladding-free and directionally coupled topological devices.

International ethical documents in the practice of regulating journalism

RELEVANCE. In the modern world, globalization leads to the formation of a single information space and the blurring of boundaries between local and global media. The purpose of the study is to find out how international standards of journalism relate to national and religious ethical norms in the context of globalization, and what prospects exist for the formation of global ethics. The study is aimed at identifying problems and prospects in the field of international standards of journalistic ethics in the context of globalization.MATERIALS AND METHODS. The object of the study is international and national documents regulating the activities of the media, as well as specific codes adopted in various cultural and religious traditions. We applied a critical analysis of existing approaches and norms in the field of journalism and human rights, as well as possible contradictions and problems associated with the unification of standards. An interdisciplinary approach is used to analyze complex issues related to globalization and journalism.RESULT AND DISCUSSION. It is shown that, despite globalization and increased international interaction, there is significant diversity in the understanding and application of ethical standards in journalism. However, there is a tendency towards the formation of global ethics, despite existing cultural and religious differences. An example is the gradual approach of Muslim countries to international human rights standards, as well as efforts to take into account the specifics of different cultures in international documents regulating the activities of the media. CONCLUSION. The study confirms the possibility and necessity of developing universal ethical principles of journalism that take into account the diversity of cultural and religious traditions. At the same time, the role of international documents in promoting dialogue and mutual understanding between journalists from different countries is emphasized. In the future, additional research is required on the practical application of international recommendations in national media systems.

Reporting Cameroon’s Anglophone Crisis in a Hybrid Media Environment: How Citizen Journalists and Traditional Media Collaborate and Compete

ABSTRACT This study examined how Cameroonian legacy media and citizen journalists have collaborated or competed to report on the Anglophone crisis in Cameroon since October 2016. Using Chadwick’s hybrid media system theory, semi-structured interviews were conducted with 41 Cameroonian legacy media reporters, editors and citizen journalists. The results show that when reporting on political crises, new relationships are established between legacy media and citizen journalists that grow into formalised collaborations. Mainstream media reporters and citizen journalists either collaborate or compete to report on the crisis. Some citizen journalists both cooperate with traditional media and run their own reporting platforms, while professional journalists working for established media outlets create platforms of their own to freely report issues that would otherwise be censored on traditional media outlets. The findings reveal professional journalists acknowledge the important role of citizen journalists but are cautious about fully collaborating with them at every stage of the news production chain.

A new framework for the analysis of media systems and media organisations

This article asks: How can we best conceptualise and analyse media systems and media organisations today? A discussion of approaches to media systems and organisation analysis shows that many of them seem to assume the correctness of Francis Fukuyama’s claim that liberal democracy has after the breakdown of the Soviet system been universalised. This article argues that the contemporary world situation shows that Fukuyama’s concept of the end of history is wrong and that we, therefore, need to rethink approaches to media systems and organisation analysis. This article introduces one such approach that is based on a concept of society that argues that all social systems and organisations have economic, political and cultural dimensions and that there is an antagonism between self-management and alienation. The article builds on and extends a typology of media organisations introduced by Colin Sparks. It introduces a systematic model of 12 different types of media organisation and six types of media systems. It stresses the importance of discerning between and analysing the interactions of capitalist media, public service media, civil society media, state media, authoritarian media and democratic media.

Evolutionary regulatory dynamics in a pluralist and polarized journalism landscape: a case study of the normative framework in Spanish media

Within the European Union, the pluralist polarized journalistic model suggests the presence of journalistic cultures rooted in the connections between political parties and media organizations. In this classical framework, the state exerts significant intervention to influence a media system characterized by lower levels of professionalization. In this regard, Spain serves as a well-examined example of a pluralist polarized Western democracy. Our study entails a systematic review based on two distinct dimensions. Firstly, we scrutinized all legal documents pertaining to media regulation in Spain published between the Spanish transition and the present 1977–2024. From this perspective, we propose a chronological evolution to categorize this extensive collection of norms. Secondly, we complement our primary source assessment with an examination of secondary sources to validate the proposed evolution. Our findings indicate that the Spanish media regulation is evolving due to two pivotal factors: the influence of the European Union and the preservation of the narrative established during the transition to democracy. While contemporary communication grapples with issues such as the rise of artificial intelligence, journalistic instability, algorithmic communication, and fragmented user consumption, these areas are only addressed peripherally within the Spanish media normative context.

Epistemic Vulnerability: Theory and Measurement at the System Level

ABSTRACT Research about the epistemic crisis has largely treated epistemic threats in isolation, overlooking what they collectively say about the health of news environments. This study integrates the literature on epistemic problems and proposes a broadly encompassing framework that departs from the traditional focus on falsehoods: epistemic vulnerability. This framework is an attempt to more fully capture the erosion of authority and value conferred to political information, which has put stress on the public spheres of many democracies. The study develops the EV index to quantify this phenomenon at the system level in a comparative manner. Using OLS regression, I test the relationships between the EV index and various structural characteristics of political and media systems. Findings are remarkably consistent with established typologies of media systems. Northern European countries exhibit greater epistemic resilience, while the US, Spain, and Eastern Europe are more vulnerable. The study also offers strong evidence that populism, ideological polarization, and political parallelism contribute to higher levels of epistemic vulnerability. Conversely, public media viewership and larger party systems are associated with more epistemically resilient societies.

The need for residential housing for foreigners who reside is a basic right that should be considered. Foreigners who have competencies in the field of tourism, managers, and other expertise for the Indonesian state are very realistic because the knowledge of foreigners' work skills for progress is mostly owned by foreigners. Indonesia as a country that will lead to progress is in dire need of knowledge and skills in various fields of technology, management and increasing resources both human and natural resources. The research method is carried out with the type of normative legal research method, with the source of primary legal material Government Regulation of the Republic of Indonesia Number 103 of 2015 concerning Ownership of Residential Houses or Occupancy by Foreigners Residing in Indonesia, and other laws and regulations related to the issues discussed. While secondary legal materials are library books, journal articles on line journal system, scientific papers, and reviews in the mass media and others. The results of the study indicate that there is conformity between the Republic of Indonesia Government Regulation Number 103 and the Republic of Indonesia Government Regulation in Article 4 letter a and number 1 of Number 10 of 1996 concerning Cultivation Rights, Building Rights and Land Rights Article 39 letter e and land objects Article 40 letter c, as well as the Republic of Indonesia Government Regulation Number 18 of 2021 concerning Land Management Rights, Land Rights, Flat Housing Units and Land Registration Article 49 paragraph (1).

Effect of porous media heterogeneity and FeS re-generation for multiple cycles on arsenic immobilization under in-situ conditions

Arsenic (As) contamination in groundwater is a well-established concern. Several studies have explored the possibility of immobilizing arsenite [As (III)] in-situ within the aquifer. Recent studies show a uniform distribution of ferrous sulfate (FeS) synthesized within homogenous porous media and demonstrated promising performance in immobilizing As(III). Upscaling from bench-scale to field-scale systems involves the integration of physical and chemical heterogeneities. Thus, the distribution of reducing agent (i.e., FeS), subsequent capturing of As(III) in the upscaled heterogeneous porous media system is a complex and uncertain phenomenon. Therefore, this study focuses on assessing the performance of FeS when synthesized for multiple cycles under constant flow and constant head conditions for immobilization of As(III) through a heterogeneous porous media system. A 3-D heterogenous porous media system is first simulated using a sequential indicator simulator model (SISIM). Then, the same heterogeneous media is prepared in the laboratory by packing three different-sized sand within a 3-D tank (0.67 m × 0.40 m × 0.40 m) which is subdivided into a total of 150 grids (0.096 m × 0.08 m × 0.08 m). FeS is synthesized in-situ by sequential injection of sodium sulfide (Na2S) and ferrous sulfate (FeSO4‧6H2O), as detailed in the previous study. The outcome of the study suggests that flow within the model subsurface porous media is non-uniform and follows an inter-connected preferential flow path. The progression of in-situ synthesized FeS is faster in the areas of higher hydraulic conductivity. The immobilization of As (88%) is promising by FeS synthesized within heterogeneous porous media. An overall reduction of porosity (7.7%) and hydraulic conductivity (68.3%) are observed, which is more predominant along the preferential flow path where deposition of FeS is significantly higher. To maintain constant flow rate, 60% increase in head difference is required. Whereas the flow rate decreases by 47.2% when constant head condition is adopted. Overall, the newly synthesized FeS shows promising performance in immobilizing As(III) within heterogeneous model subsurface porous media; however, there might be some possibility of pore-clogging and bypassing of flow due to deposition and subsequent retention of As, which may impact the As removal efficiency in the longer run.

Four types of video-on-demand markets: Comparing the development of European VoD

The European video-on-demand (VoD) market has grown rapidly over the past decade, but differences across European nations persist. While the US-based globally operating players Netflix, Amazon and Disney+ dominate the subscription video-on-demand (SVoD) market, VoD services emerging from the legacy media industries and funded by means other than subscription shaped the early development of the European VoD market. This article maps and compares the development of the VoD market within the European Union with a focus on the idiosyncrasies in uptake and offer of VoD in different countries. Building on previous studies of national media systems, the article develops four comparative dimensions for the case of the European VoD market and operationalizes them using quantitative data from the European Audiovisual Observatory (EAO) and Eurostat from the period 2016–22. The comparative data analysis results in a grouping of countries, according to similar levels of market penetration and diversity of catalogue and content offers, while accounting for differences in size, concentration in the SVoD market and levels of market intervention within these clusters. These four types of VoD market development offer a contextualization to nation or service-specific case studies of players in the European market and a basis for hypotheses to explain these differences.

Signalling media professionalism: comparative social constructions of RT and CGTN

ABSTRACT The messaging content of Russia Today (RT) and China Global Television Network (CGTN) provides alternatives to those offered in mainstream western media. Comparative studies point to RT’s aggressive, ideological rhetoric and CGTN’s more tacit, celebratory, and culture-focused approach. This study adds to these understandings by examining how messaging strategies construct media professionalism – one of the four historic pillars of media systems analysis – to delegitimize media systems of rival states and build credibility of their own platforms and by assessing the dialectical role of key oppositional voices to Western media hegemony in the digital sphere. Using a mixed methods approach, we analyzed thousands of RT and CGTN’s Facebook posts across language accounts between 2017 and 2022. The study documents that RT and CGTN utilise arguments by comparison to assess competing news outlets and redefine scholarly modes of assessing media professionalism. The study identified four metrics used by RT and CGTN to evaluate media professionalism: source attribution, adherence to positive news values, distinctions from negative news standards of competing outlets, and relative commitment levels to free expression. It further reveals differences in RT and CGTN’s language-based, message targeting in relation to media professionalism.
