Media and Immersive Technologies in Higher Education

Media and Immersive experiences in higher education provide students the opportunity to engage with course content in ways that were not previously possible. The Media and Immersive team at the University of New South Wales, Sydney (UNSW) was created to support academics in developing innovative solutions and to foster engagement from students with new forms of content delivery. This paper will outline the affordances and challenges of media and immersive applications at UNSW and examine the possibilities that artificial intelligence and open educational resources offer in overcoming some of the barriers to widespread adoption.

Future challenges of contrast media in radiology

Contrast media (CM) were first used soon after the discovery of X-rays in 1895. Ever since, continuous technological development and pharmaceutical research has led to tremendous progress in radiology, more available techniques and contrast media, and expanded knowledge around their indications.A greater prevalence of chronic diseases, population ageing, and the rise in diagnosis and survival times among cancer patients have resulted in a growing demand for diagnostic imaging and an increased consumption of CM.This article presents the main lines of research in CM development which seek to minimise toxicity and maximise efficacy, opening up new diagnostic and therapeutic possibilities through new molecules or nanomedicine. The sector, which is continuously evolving, faces challenges such as shortages and the need for more equitable and sustainable practices.

Innovative xanthan gum-based nanocomposites for asphaltene precipitation prevention in shale and carbonate rocks

Asphaltene deposition in porous media creates many challenges in porous media. This study synthesizes ZnO/SiO2/xanthan nanocomposites (NCs) to adsorb asphaltene and reduce its effect on the shale and carbonate rocks. NCs structure is analyzed using SEM, EDX, BET, and FTIR tests. Also, the rocks' surface is analyzed by an atomic force microscopy (AFM) test after 48 and 96 h of contact with 20 ppm NCs and 20 mg asphaltene. Core flooding tests are performed on shale rocks using 20 ppm NCs at 5500, 4000, and 2500 psi at 48 h. Using AFM in calcite and dolomite formations and selecting core flooding tests based on that are new scenarios that followed in this paper. FTIR results confirm asphaltene adsorption on NCs's surface by changing 854 and 962 cm−1 peaks. AFM tests confirmed asphaltene adsorption on NCs surface, too. Average roughness, root mean square roughness, peak to valley roughness, and average size of the shale were higher than the carbonate sheets. At 20 ppm NCs in shale reservoirs, permeability reduction in porous media was increased up to 39.5 %, and asphaltene precipitation decreased from 8.95 and 20.06 wt% to 2.25 and 10.25 wt%, which shows our suggested scenarios were efficient.

Managing Pharmaceutical Promotion Mix in the Rise of Social Media

ABSTRACTA manufacturer of a branded prescription drug typically uses traditional promotional tools to communicate with consumers (i.e., direct‐to‐consumer advertising) and physicians (i.e., detailing, sampling, and journal advertising). These promotions seek to enhance brand drug visibility and, eventually, increase brand sales. As medical communication norms generally dictate how healthcare information is communicated, the emergence of social media challenges such norms and potentially inflates (or deflates) the efficacy of pharmaceutical marketing communication. In such situations, a crucial research question revolves around how marketers will adjust their promotional strategies. In this study, the authors analyze the longitudinal data of 41 brand drugs from 7 therapeutic classes between 2007 and 2014. Through the lens of signaling theory, they empirically show that the volume and valence of social media posts can enhance or hinder the sales impacts of different promotional activities. Specifically, the volume and valence of social media posts have the potential to amplify the sales impact of detailing and direct‐to‐consumer advertising, while diminishing the effects of sampling and journal advertising. The volume and valence of brand drug mentions as well as consumer passion toward the brand drug display similar effects on the efficacy of pharmaceutical promotions. The findings shed new light on conventional pharmaceutical promotion practices in the presence of social media and provide novel implications for promotion mix management.

Reflection Measurement of the Scattering Mean Free Path at the Onset of Multiple Scattering.

Multiple scattering of waves presents challenges for imaging complex media but offers potential for their characterization. Its onset is actually governed by the scattering mean free path ℓ_{s} that provides crucial information on the medium microarchitecture. Here, we introduce a reflection matrix method designed to estimate this parameter from the time decay of the single scattering rate. Our method is first validated by an ultrasound experiment on a tissue-mimicking phantom before being applied invivo to a human liver. This Letter opens important perspectives for quantitative imaging of heterogeneous media with waves, whether it be for nondestructive testing, biomedical, or geophysical applications.

The challenges of media and information literacy in the artificial intelligence ecology: deepfakes and misinformation

In the ecosystem of artificial intelligence (AI), generative models enable the creation of hyper-realistic manipulations that are extremely plausible due to the precision of the audiovisual objects. These deepfakes are undetectable thanks to their components, which heightens concerns about the distortion of reality in the information ecosystem and how the ability to distinguish between real and fake audiovisual content affects public trust and democratic systems. This is a major challenge for media and information literacy if it is to combat misinfor­mation effectively. In this context, this study presents the results of a quasi-experiment conducted with 80 young people from the Community of Madrid (Spain) to assess their ability to detect deepfakes in immersive environments and to establish whether the context-identifying elements that enable detection of the reputation of the media source shape the credibility of the images. The results show that the images take precedence over the context identifiers, preventing a critical reading of the information that would make it possible to detect visual forgeries, something that is reinforced by their exceptional verisimilitude. It is concluded that the new post-humanist biome of virtual reality and artificial intelligence requires a reorien­tation of media and information literacy to raise the public’s awareness and educate them to make them less susceptible to disinformation based on deepfakes created with generative models.

A novel meshless numerical simulation of oil-water two-phase flow with gravity and capillary forces in three-dimensional porous media

This paper presents a novel fully implicit scheme for simulating three-dimensional (3D) oil-water two-phase flow with gravity and capillary forces using the meshless generalized finite difference method (GFDM). The approach combines an implicit Eulerian scheme in time with a GFDM discretization method in space to compute implicit solutions for the pressure and saturation in the flow control equations. The research introduces an L2 norm error formula and conducts a sensitivity analysis on the impact of varying influence domain radii on computational accuracy within the Cartesian node collocation scheme. Findings suggest that larger influence domain radii correspond to reduced computational accuracy, providing a preliminary guideline for selecting the domain radius in 3D GFDM applications. Overall, this paper presents an effective and precise meshless method for addressing two-phase flow challenges in 3D porous media, highlighting the promising prospects of GFDM in numerical simulations.

ENHANCING SECURITY IN NIGERIA: THE IMPLICATIONS OF SOCIAL MEDIA-BASED CRIME REPORTING

With the widespread use of social media platforms, individuals have increasingly turned to these platforms to report crimes, creating an evolving landscape for law enforcement and security agencies. Social media-based crime reporting has emerged as a transformative approach to public safety, offering real-time updates, accessibility, and community engagement. This study examines how social media platforms like Facebook and Twitter promote community mobilization and real-time information sharing by applying Information Diffusion Theory (IDT) and Social Network Theory (SNT). Notable examples, such as the Aluu Four lynching, End-SARS movement, Chibok kidnapping and the 2023 presidential elections amongst other events, demonstrate how social media plays a crucial role in increasing public knowledge, coordinating group efforts, and impacting legislative reforms. However, this innovative method of reporting also brings forth several security implications that demand careful consideration. By examining the advantages and challenges of social media for crime reporting, this study aims to provide insights into how such practices can enhance security measures while mitigating potential risks. This study, therefore, explores these security concerns and strategies for enhancing the security implications of social media-based crime reporting. It discusses the potential risks of misinformation, privacy issues, tipping off perpetrators, and the inadvertent exposure of victims and witnesses. The results emphasize the importance of adopting a well-rounded strategy to utilize the capabilities of social media for reporting crimes, while also acknowledging the difficulties it presents. The study highlights the need for collaboration between law enforcement agencies, policymakers, social media platforms, and the public to develop a robust legal framework, promote responsible reporting practices, and protect evidence integrity. The study therefore recommends the use of sophisticated verification technology, the establishment of responsible reporting criteria, collaboration with social media platforms, and the implementation of strong privacy protection measures.

Academia and journalism: Two different worlds? How scientific institutions can successfully collaborate with journalistic organizations

Traditionally, researchers have played only a limited role as experts or qualified sources for journalists—and journalists were the subject of investigation for researchers rather than cooperation partners. The rapid pace of transformation processes in media use poses various challenges for media practitioners today, which is why they increasingly rely on the support of media researchers and their valuable insights into consumer attitudes and behaviour. However, the cooperation between scientific institutions and media practitioners is marked by many challenges and apart from individual temporary projects, lasting collaborations have not yet been established. This paper presents a long-term transfer initiative that aims to promote news use and news literacy among young people in close cooperation between a scientific institution and a wide range of private and public service media. Using this initiative as an example, we analyse the opportunities, challenges, and productive dynamics that result from this project. Based on our experience, we propose four main pieces of advice for how researchers can enhance long-term collaboration with newsrooms.

The Global Development and Communication Mechanisms in the New Media Era: Multiculturalism and the Global Communication of New Media

In the era of new media, social media has become an essential platform for global information dissemination and cultural exchange. The globalization of social media has changed the way of information dissemination of traditional media, making the cultural values of different countries and regions blend and collide more frequently. This report will analyze how users with different cultural backgrounds interact and disseminate content on social media platforms, and reveal the potential and challenges of new media in promoting cross-cultural communication, developing multicultural and resolving cultural conflicts. In addition, through research methods to analyze the interaction of users from different cultural backgrounds on new media platforms and the dissemination of content, the research objects will include active social media users of different ages, different countries and cultural backgrounds. This report finds that new media plays a vital role in resolving cultural conflicts and promoting cultural exchanges, but it needs to be further optimized in terms of communication mechanisms to create a harmonious network atmosphere. Additionally, this report proffers recommendations for the refinement of new media communication mechanisms. By enhancing the efficacy of these channels, it becomes increasingly feasible to address the cross-cultural communication imperatives of a global user base, thereby facilitating the promotion of cultural integration and fostering a deeper, more nuanced understanding of diverse societal contexts on a global scale.

Cyber social proof and hazard: Investigating the impact of social media on pediatric burn incidents – Analysis and comprehensive literature review

Investigating the growing concern of pediatric burn injuries caused by social media challenges. Adolescents, seeking fame or succumbing to peer pressure, engage in risky behaviors, recording and sharing them online. The study presents two case reports detailing severe burn injuries resulting from such challenges, highlighting the physical and psychological toll on affected children and their families. In Case Report 1, a 14-year-old suffered severe burns attempting a TikTok challenge involving igniting a soaked t-shirt. The patient's critical condition necessitated intensive care, surgical procedures, and skin grafts, accompanied by complications like anemia and sepsis. Case Report 2 features a 9-year-old who sustained extensive burns while attempting another social media challenge. Treatment included escharolysis, skin grafts, and surgeries, with complications managed during the recovery process. A literature review explores social media-generated burn injuries, revealing their physical and psychological impact. The influence of social proof and peer pressure on adolescents' behavior in the digital age is discussed. The pandemic's effect on mental health is considered, emphasizing the vulnerability of adolescents to such challenges. In conclusion, the paper highlights the rising incidence of teen burn injuries linked to social media challenges. Urgent measures are needed to restrict the promotion of risky behaviors on social platforms. Alongside state-of-the-art burn treatments, comprehensive psychological care is essential for young patients and their families to cope with trauma. Increased content monitoring and the dissemination of prevention materials are recommended to mitigate the occurrence of such incidents.

Challenges for campus and community media in Asia-Pacific diversity

The ‘watchdog’ model has created a journalism culture that is too adversarial and creates conflicts rather than helping to solve today’s problems/conflicts. The panellists assess new journalism paradigms in the Asia-Pacific region where the media is able to make powerful players to account for facilitating the development needs of communities, especially those in the margins of society. A challenge for contemporary journalism schools is to address such models in a global context of ‘development rights’ with the UN’s Sustainable Development Goals as a benchmark. In the Pacific Islands context, journalists face a challenging news reporting terrain on their news beats, especially in the Melanesian countries of Fiji, Papua New Guinea, Solomon Islands and Vanuatu. Besides dealing with political instability, coups, civilian unrest and complex developmental issues, journalists must contend with hostile governments and draconian media legislation. The talents, idealism and storytelling skills of Pacific journalists can be cultivated and strengthened to produce independent platforms and models of journalism that challenge the status quo. Examples of this campus strategy include Radio Pasifik, Wansolwara, Pacific Scoop and Asia Pacific Report.
