Refining CycleGAN with attention mechanisms and age-Aware training for realistic Deepfakes

In the evolving landscape of deep learning technologies, the emergence of Deepfakes and synthetic media is becoming increasingly prominent within digital media production. This research addresses the limitations inherent in existing face image generation algorithms based on Generative Adversarial Networks (GAN), particularly the challenges of domain irrelevancy and inadequate facial detail representation. The study introduces an enhanced face image generation algorithm, aiming to refine the CycleGAN framework. The enhancement involves a two-fold strategy: firstly, the generator's architecture is refined through the integration of an attention mechanism and adaptive residual blocks, enabling the extraction of more nuanced facial features. Secondly, the discriminator's accuracy in distinguishing real from synthetic images is improved by incorporating a relative loss concept into the loss function. Additionally, this study presents a novel model training approach that incorporates age constraints, thereby mitigating the effects of age variations on the synthesized images. The effectiveness of the proposed algorithm is empirically validated through comparative analysis with existing methodologies, utilizing the CelebA dataset. The results demonstrate that the proposed algorithm significantly enhances the realism of generated face images, outperforming current methods in terms of Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index Measure (SSIM), while also achieving notable improvements in subjective visual quality. The implementation of this advanced method is anticipated to substantially elevate the efficiency and quality of digital media production, contributing positively to the broader field of digital media creation.

Life cycle assessment of Beefy-9 and Beefy-R serum-free culture media for cell-cultivated beef production

The sustainable production of cell-cultivated meat requires the use of environmentally friendly nutrients. Culture media, which provides the necessary nutrients for cell proliferation and differentiation is a major contributor to the environmental impacts of cultivated meat production. Fetal bovine serum (FBS) is problematic due to animal sourcing, ethical concerns, and high cost. Beefy-R and Beefy-9 are experimentally validated, serum-free cell culture media designed for bovine myoblast culture. While both formulations include basal media, ascorbic acid, sodium selenite, recombinant proteins, and growth factors, Beefy-9 and Beefy-R contain recombinant albumin and rapeseed protein isolates (RPI) to replace FBS, respectively. While these culture media do not include animal-sourced components, their environmental impacts have not yet been investigated. In this study, life cycle assessment (LCA) was performed to estimate the environmental burdens of Beefy-9 and Beefy-R culture media production and identify hotspots for optimization. Uncertainty was assessed through sensitivity and scenario analyses, as well as Monte Carlo simulation. Our results demonstrate that Beefy-R has significantly lower environmental impacts compared to Beefy-9 in 13 out of 18 evaluated impact categories. For instance, the global warming potential (GWP) of Beefy-R was almost five times lower when compared against that of Beefy-9 production. In Beefy-R, despite the absence of recombinant albumin, recombinant proteins and growth factors were hotspots, accounting for 41 %, 5.9 %, and 12 % of GWP, land use, and water consumption impacts, respectively. This study confirms that RPI can be a more sustainable substitute for recombinant albumin in bovine myoblast serum-free media formulations. Additional research is required to identify low-impact alternatives for other recombinant proteins and growth factors in culture media.

Developing Hyperpolarized Butane Gas for Ventilation Lung Imaging.

NMR hyperpolarization dramatically improves the detection sensitivity of magnetic resonance through the increase in nuclear spin polarization. Because of the sensitivity increase by several orders of magnitude, additional applications have been unlocked, including imaging of gases in physiologically relevant conditions. Hyperpolarized 129Xe gas recently received FDA approval as the first inhalable gaseous MRI contrast agent for clinical functional lung imaging of a wide range of pulmonary diseases. However, production and utilization of hyperpolarized 129Xe gas faces a number of translational challenges including the high cost and complexity of contrast agent production and imaging using proton-only (i.e., conventional) clinical MRI scanners, which are typically not suited to scan 129Xe nuclei. As a solution to circumvent the translational challenges of hyperpolarized 129Xe, we have recently demonstrated the feasibility of a simple and cheap process for production of proton-hyperpolarized propane gas contrast agent using ultralow-cost disposable production equipment and demonstrated the feasibility of lung ventilation imaging using hyperpolarized propane gas in excised pig lungs. However, previous pilot studies have concluded that the hyperpolarized state of propane gas decays very fast with an exponential decay T 1 constant of ∼0.8 s at 1 bar (physiologically relevant pressure); moreover, the previously reported production rates were too slow for potential clinical utilization. Here, we investigate the feasibility of high-capacity production of hyperpolarized butane gas via heterogeneous parahydrogen-induced polarization using Rh nanoparticle-based catalyst utilizing butene gas as a precursor for parahydrogen pairwise addition. We demonstrate a remarkable result: the lifetime of the hyperpolarized state can be nearly doubled compared to that of propane (T 1 of ∼1.6 s and long-lived spin-state T S of ∼3.8 s at clinically relevant 1 bar pressure). Moreover, we demonstrate a production speed of up to 0.7 standard liters of hyperpolarized gas per second. These two synergistic developments pave the way to biomedical utilization of proton-hyperpolarized gas media for ventilation imaging. Indeed, here we demonstrate the feasibility of phantom imaging of hyperpolarized butane gas in Tedlar bags and also the feasibility of subsecond 2D ventilation gas imaging in excised rabbit lungs with 1.6 × 1.6 mm2 in-plane resolution using a clinical MRI scanner. The demonstrated results have the potential to revolutionize functional pulmonary imaging with a simple and inexpensive on-demand production of proton-hyperpolarized gas contrast media, followed by visualization on virtually any MRI scanner, including emerging bedside low-field MRI scanner technology.

The Public's Perception of Florence Nightingale's Legacy in the Digital Media: A Critical Discourse Analysis.

This study critically examines the public's perception of Florence Nightingale's legacy through a critical discourse analysis (CDA) of digital media, specifically podcasts and YouTube. Nightingale, who is often remembered as "The Lady with the Lamp", holds a complex identity within modern narratives that is celebrated for her pioneering contributions to nursing and public health, even if there are some disagreements about her, given the colonialist setting that may have shaped some of her opinions and decisions. This research employed CDA to analyze 25 podcasts and 18 YouTube videos, which were systematically included according to a priori inclusion criteria. The study synthesized how these media products portray Nightingale and, by extension, shape public discourse about the nursing profession. The findings reveal five thematic representations of Nightingale: as a legendary figure, a modern feminist, a dedicated statistician, a pioneer in public health, and a pivotal STEM contributor. These portrayals challenge traditional nursing stereotypes by emphasizing Nightingale's role as a rigorous scientist and reformer, suggesting broader perceptions of nurses that encompass leadership, analytical skills, and strategic thinking. The study supports the hypothesis that digital narratives significantly influence the public's understanding and appreciation of nursing, advocating for a more nuanced professional identity that integrates traditional caregiving roles with critical and analytical capabilities.

Enhancing Engagement and Autonomy in Advanced Japanese Learning as the Second Language through AI-Assisted Video Production

This study delves into the integration of generative AI in second language acquisition, particularly focusing on advanced Japanese learners' autonomy and motivation enhancement through video production. Drawing from Japan's educational guidelines and prior research, the investigation examines the roles of generative AI in language education, emphasizing ethical considerations and strategies for effective integration (Mollick Mollick, 2023). The course implemented a hybrid approach, combining language instruction with media production, where students created YouTube videos in Japanese. Their productions were supported by AI tools for language correction, narration, and content generation. Results indicate that while AI facilitated practical language learning, instructor guidance remained crucial for ensuring accuracy and contextual appropriateness. The study highlights challenges such as overreliance on AI-generated content and the need for nuanced communication in prompt engineering. Despite these challenges, students demonstrated cultural understanding and improved nonverbal communication skills through video production. Future research aims to analyze students' reflections on their experiences, shedding light on their insights and future applications of AI in language learning.

Analyzing California Student Media Festival winning videos

ABSTRACT The researchers conducted an extensive examination of winning student videos from the California Student Media Festival (CSMF) spanning the years 2009–2023. This content analysis aimed to gauge the quality of these videos and shed light on the diverse participation of schools in the festival. By scrutinizing high-quality videos across different school levels and years, the researchers sought to identify common technical and content factors, particularly those that reflect media and information literacy. The analysis also examined the patterns of participating schools. The analyzed videos not only provided insights into the evolving interests and agendas of students but also showcased their adeptness in embracing emerging technologies and employing a variety of digital tools. Notably, the presence of media assignments and teacher guidance underscored the vital role of school support and instruction in nurturing students’ media production skills. However, the study also revealed that there remains untapped potential for growth in the realm of media literacy education.

Text sentiment analysis and classification based on bidirectional long and short term memory networks

In this study, we explored the method of text sentiment analysis and classification using bi-directional long and short-term memory networks, which brings new ideas to the field of sentiment classification. In the text pre-processing stage, we processed chat phrases, non-alphanumeric characters, deactivated words, numbers, special characters, blanks, and addresses to convert the raw text data into numerical data that can be processed by the model. Subsequently, word frequency statistics were conducted for texts of different mood types to analyse the frequency of occurrence of different words in texts of different mood types. By introducing a bi-directional long and short-term memory network model for training, we observed the accuracy and loss value performance on the training and validation sets. The accuracy of the training set increases from the initial 94.6% to 99.5%, and the accuracy of the validation set gradually grows to 99.4%; at the same time, the loss value of the training set decreases from the initial value of 0.2075 to 0.0194, and the loss value of the validation set gradually increases from the initial value of 0.0538 to 0.0372. This indicates that the bi-directional long short-term memory network achieves a significant and stable performance improvement. The confusion matrix results for the test set show that our model achieves more than 99% prediction accuracy on the test set. This implies that our proposed method can efficiently classify textual sentiment with high prediction accuracy. This research result helps to improve the effectiveness of the application of sentiment analysis techniques in the fields of social media opinion monitoring and product review analysis, and provides a useful reference for further deepening the research on text sentiment analysis. In conclusion, this study achieves the optimisation of the text sentiment classification task by means of a bidirectional long and short-term memory network model, and achieves satisfactory results. In the future, the model performance and generalisation ability can be further improved by combining more corpus and optimising the model structure, so as to be better applied in real-world scenarios.

Doctors',Patients' and Physician Associates' Perceptions of the Physician Associate Role in the Emergency Department.

The Emergency Department (ED) has seen increased patient attendance and difficultymeeting demands. New healthcare professions such as Physician Associates (PAs) are being utilised to complement the existing medical workforce. Despite the growth of their professions in the United Kingdom, little evidence is available about the perceptions of their roles. This study aims to provide evidence of doctors', PAs' and patients'perceptions of the PA role in the UK ED. A mixed methods approach consisted of the following: 1. An online exploratory survey of ED doctors at one English EDover 1 month (February-March 2022). 2. Post consultation semi-structured patient questionnaires over 2 weeks (April 2022). 3. Semi-structured virtual interviews with ED consultants across thefour regions of theUnited Kingdom (3 months in 2022). 4. Semi-structured virtual interviews with ED PAs across thefour regions of theUnited Kingdom(3 months in 2022). The analysis methods that were used includedfrequency counts and percentages from closed questions, andhybrid thematic analysis of free text and interview transcripts. Four ED consultants and four ED PAs across the United Kingdom were interviewed. Twenty-eight ED doctors participated in the online survey. Fifty-seven patients completed the post consultation questionnaire. Four main themes (PAs being fit for purpose; patient recognition of PAs, PAs providing continuity of care, and future PAs and regulation) were deduced as per the General Medical Council, Good Medical Practice domains (knowledge, skillsand development; patients, partnership and communication; colleagues, culture and safety; and trust and professionalism). Other subthemes were induced via hybrid thematic analysis. In this study, doctors and patients had mixed comments about the role of PAs. Most of them were positive as doctor participants perceived PAs to be knowledgeable, highly skilled, with mostly good communication skills, team players, providing continuity of care and overall being fit for purpose. However, some doctor participants commented negatively about PAsfor providing little quality healthcare and being inexperienced. There was a desire for career progression amongthe PA participants and a need to work to their full potential. Although the clinicians of this study displayed a clear understanding of the PA role in the ED,a high frequency of surveyed patients mistook PAs for doctors. It was suggested that future PAs could complete a postqualification programme in emergency medicine, combine roles, be paid on an alternative scaleand be formally regulated. In this study, mixed views were expressed by ED consultants, ED junior doctorsand patients regarding the role of the PA in the ED. Stakeholders can use the information presented to develop a better understanding of the perceptions of the PA role within the UK ED. The Patient and Public Involvement and Engagement (PPIE) group, led by Healthwatch, made significant contributions to the study's design by providing valuable feedback on the information sheets and consent forms utilised. The patients' responses helped guide the study's direction and shape its future work. As part of the dissemination activities, the study findings was shared with both the PPIE team and Healthwatch media production team.

Insights on associations between the frequency of use of diverse social media products and social networks use disorder tendencies from a German speaking sample

ObjectiveIn the present work we investigate how individual differences in at least occasionally using distinct social media platforms is linked to social networks use disorder (SNUD) tendencies. A final sample of n = 2200 participants filled in the AICA-C-9 measure to get insights into individual differences in overuse of social media and participants also indicated which platforms they used at least once a month.ResultsThe analysis revealed a robust positive association between number of at least occasionally used social media apps and SNUD tendencies (r = .44, p < .001). Further, platforms differed in terms of their “addictive potential”, if one takes associations between frequency of distinct platforms use and SNUD tendencies as a proxy for this (and of course the actual descriptive statistics of the SNUD scale for the (non-)frequent user groups of the different platforms). In this regard, at least occasionally using some platforms (here Tumblr, Twitter and TikTok) was associated with highest SNUD tendencies. Moreover, largest differences in terms of effect sizes between the occasional and non-occasional user groups regarding SNUD scores could be observed for Instagram, WhatsApp, and TikTok. The present work bases on data from a larger project investigating associations between SNUD and tobacco use disorder.

The Influence of Social Media Marketing , Product Quality and Price Perceptions on Purchasing Decisions for Some Skincare Products

There are several common problems in the beauty industry related to these variables. In social media marketing, the level of competition is very high, with many brands vying for consumer attention. Small brands may struggle to stand out among the big brands. Products that don't suit a consumer's skin type or concerns can lead to negative experiences and damage a brand's reputation. Consumers' experiences influence their reviews and recommendations, which can have a positive or negative impact on the company (Susanti &amp; Gunanto, 2022) .This research aims to identify the influence of social media marketing, product quality, and price perceptions on purchasing decisions for Somethingnc skincare. The sample was determined using a purposive sampling technique with a total of 100 respondents. The validity and reliability of the questionnaire were tested using the SPSS 23 tool. The results of this research show that social media marketing, product quality, and price perceptions have a significant positive influence on purchasing decisions.

After the killing fields: Post-pandemic changes in journalism employment in Australia and Aotearoa New Zealand

This article continues a longitudinal national study of journalism employment in Australia and contributes to new understandings of journalism employment in Australia and Aotearoa New Zealand. Results suggest a shift in the organisational landscape of the media in Australia, with an expansion of large organisations at the ‘top,’ and a considerable loss of small micro-ventures (largely based online) at the ‘bottom.’ Implications include stronger centralised editorial control at the corporate level, urbanisation and homogenisation of media producers and product, and reduced opportunities for creative entry-level roles.

De-figuring and Blurring Bodies from Cinema to Data Moshing

In the post-medial era of maximum digital definition of images (Eugeni 2015; 2021), a part of the aesthetic research on images work on the modes of the indistinct and indeterminate, the formless and the blurred (Dusi 2013; 2019). Fictional cinema and TV series, documentary photography that investigates movement and performance, experimental video art that works on the limits of vision, use operations of “imperfect” visibility dominated by a subjectification and non-closure of meaning. They decline the modes of filtered or blurred vision, for example alternating montage of sharp and blurred images or using indistinct images within a single frame. Blurring the images is a way to filter the opposition between visible and invisible and between presence and absence. It complicates the game between real and virtual, opening the audio-visual media products to the drift of interpretations and the vertigo of potential worlds. For some directors (i.e. David Lynch) this type of imperfect vision and the mechanisms of de-figuration by blurring or rarefaction are a way of narrating the loss of identity of the subject (Ricoeur 1990) and become structural mechanisms that affect representation. Nowadays we also face a new manipulation of moving images, producing melted and liquefied images, a collective and playful sharing of a practice that until ten years ago was considered experimental. It is the case of data moshing and glitching, actually an exercise in rewriting and manipulating the algorithms and an intervention on the digital medium that reveals its capacity for decomposition and manipulation of the image.
