Taking a Closer Look: "Evaluating Online Video Content for Rehabilitation after Distal Radius Fracture".

Background: Fractures of the distal radius are among the most common bone injuries, and their frequency is constantly increasing, leading to an elevated need for subsequent rehabilitation. This growing need has led to the emergence of online content aimed at providing guidance on rehabilitation. Nonetheless, unreviewed online content raises concerns about its reliability; therefore, the objective of this study was to evaluate the quality, reliability, and comprehensiveness of online videos concerning rehabilitation following a distal radius fracture. Methods: A total of 240 YouTube videos were screened, identifying 33 videos that met the inclusion criteria. These selected videos were evaluated by five independent experts from various professional groups, using the Global Quality Scale, the DISCERN reliability tool, and the JAMA Benchmark Score, as well as a structured set of questions to assess their comprehensiveness and coverage of pertinent aspects. Results: The observers' assessment of the Global Quality Scale exhibited a broad spectrum of viewpoints, indicating considerable variability in evaluations. In most cases, therapy aligned well with the diagnosed condition, and most raters deemed the indication and instruction in the videos acceptable. A proportion of 87% of the videos was deemed suitable for home training by at least three raters. However, a concerning trend emerged, as potential risks and pitfalls were scarcely addressed. Conclusions: The moderate overall quality of the videos and the divergence in expert opinions highlight the need for a regulatory authority to ensure adherence to guidelines and maintain high-quality content. Additionally, our results raise concerns about the applicability of established assessment tools in this context.

Delirium care burden of intensive care nurses caring for patients undergoing open-heart surgery: A mixed-method research.

Delirium is an acute confusional state characterized by inattention, cognitive dysfunction and an altered level of consciousness. Delirium causes negative outcomes in patients, and patients with delirium increase the workload of nurses. Therefore, it is important to recognize the challenges and burdens experienced by nurses caring for patients with delirium. To determine the subjective burden experienced by intensive care nurses caring for patients who have undergone open-heart surgery. A mixed-method sequential explanatory design. A non-probability purposive sampling method was used for the quantitative stage. Using OpenEpi, we employed the method of sample calculation with an unknown universe. The sample size of the quantitive study comprised 130 nurses. Quantitative data were collected with Google survey. For gathering qualitative data, online video interviews were conducted with 10 nurses, an interpretive phenomenological approach was used and content analysis was performed. In the quantitative phase, we found that the subjective burden was high. In the qualitative phase, five main themes emerged: difficulty in recognizing delirium, physical burden, emotional burden, burden in care management of patients with delirium and the effect of patients with delirium on other patients. The nurses experienced physical and emotional burden in delirium management and felt lonely while caring for patients with delirium. Because nurses play a key role in the care of patients with delirium, reducing the burden nurses experience when caring for patients with delirium should be considered important in ensuring that this patient population receives adequate care. Delirium patients create a care burden for intensive care nurses. To reduce this burden of care, in-service training in patient management and bedside teaching support should be provided to nurses. Furthermore, the use of a valid scale to diagnose delirium should be integrated into health policies. Nurses should not be left alone in the management of delirium. Managing delirium patients with a team including physicians, nurses and professionals from other health disciplines will ensure that patients receive high-quality care, thereby reducing the care burden of nurses.

How to Develop an Online Video for Teaching Health Procedural Skills: Tutorial for Health Educators New to Video Production.

Clinician educators are experts in procedural skills that students need to learn. Some clinician educators are interested in creating their own procedural videos but are typically not experts in video production, and there is limited information on this topic in the clinical education literature. Therefore, we present a tutorial for clinician educators to develop a procedural video. We describe the steps needed to develop a medical procedural video from the perspective of a clinician educator new to creating videos, informed by best practices as evidenced by the literature. We also produce a checklist of elements that ensure a quality video. Finally, we identify the barriers and facilitators to making such a video. We used the example of processing a piece of skeletal muscle in a pathology laboratory to make a video. We developed the video by dividing it into 3 phases: preproduction, production, and postproduction. After writing the learning outcomes, we created a storyboard and script, which were validated by subject matter and audiovisual experts. Photos and videos were captured on a digital camera mounted on a monopod. Video editing software was used to sequence the video clips and photos, insert text and audio narration, and generate closed captions. The finished video was uploaded to YouTube (Google) and then inserted into open-source authoring software to enable an interactive quiz. The final video was 4 minutes and 4 seconds long and took 70 hours to create. The final video included audio narration, closed captioning, bookmarks, and an interactive quiz. We identified that an effective video has six key factors: (1) clear learning outcomes, (2) being engaging, (3) being learner-centric, (4) incorporating principles of multimedia learning, (5) incorporating adult learning theories, and (6) being of high audiovisual quality. To ensure educational quality, we developed a checklist of elements that educators can use to develop a video. One of the barriers to creating procedural videos for a clinician educator who is new to making videos is the significant time commitment to build videography and editing skills. The facilitators for developing an online video include creating a community of practice and repeated skill-building rehearsals using simulations. We outlined the steps in procedural video production and developed a checklist of quality elements. These steps and the checklist can guide a clinician educator in creating a quality video while recognizing the time, technical, and cognitive requirements.

Assessing the interplay of presentation and competency in online video examinations: a focus on health system science education

BackgroundThe integration of Health System Science (HSS) in medical education emphasizes mastery of competencies beyond mere knowledge acquisition. With the shift to online platforms during the COVID-19 pandemic, there is an increased emphasis on Technology Enhanced Assessment (TEA) methods, such as video assessments, to evaluate these competencies. This study investigates the efficacy of online video assessments in evaluating medical students’ competency in HSS.MethodsA comprehensive assessment was conducted on first-year medical students (n = 10) enrolled in a newly developed curriculum integrating Health System Science (HSS) into the Bachelor of Medicine program in 2021. Students undertook three exams focusing on HSS competency. Their video responses were evaluated by a panel of seven expert assessors using a detailed rubric. Spearman rank correlation and the Interclass Correlation Coefficient (ICC) were utilized to determine correlations and reliability among assessor scores, while a mixed-effects model was employed to assess the relationship between foundational HSS competencies (C) and presentation skills (P).ResultsPositive correlations were observed in inter-rater reliability, with ICC values suggesting a range of reliability from poor to moderate. A positive correlation between C and P scores was identified in the mixed-effects model. The study also highlighted variations in reliability and correlation, which might be attributed to differences in content, grading criteria, and the nature of individual exams.ConclusionOur findings indicate that effective presentation enhances the perceived competency of medical students, emphasizing the need for standardized assessment criteria and consistent assessor training in online environments. This study highlights the critical roles of comprehensive competency assessments and refined presentation skills in online medical education, ensuring accurate and reliable evaluations.

Constant or inconstant? The time-varying effect of danmaku on user engagement in online video platforms

PurposeAs an emerging video comment feature, danmaku is gaining more traction and increasing user interaction, thereby altering user engagement. However, existing research seldom explores how the effectiveness of danmaku on user engagement varies over time. To address this research gap, this study proposes a comprehensive framework drawing on social presence theory and information overload theory. The framework aims to explain how the effectiveness of danmaku in increasing user engagement changes over shorter time intervals.Design/methodology/approachA research model was proposed and empirically tested using data collected from 1,019 movies via Bilibili.com, one of China’s most popular danmaku video platforms. A time-varying effect model (TVEM) was used to examine the proposed research model.FindingsThe study finds that the volume of danmaku and its valence exert a time-varying influence on user engagement. Notably, the study shows that danmaku volume plays a more substantial role in determining user engagement than danmaku valence.Originality/valueThis research offers theoretical insights into the dynamic impact of danmaku on user engagement. The innovative conceptualization and measurement of user engagement advance research on pseudo-synchronous communication engagement. Furthermore, this study offers practical guidelines for effectively managing danmaku comments on online video platforms.

Persuasion and gender: experimental evidence from two political campaigns

AbstractWe investigate differential responses by gender to competitive persuasion in political campaigns. We implemented a survey and a field experiment during two mayoral elections in Italy. Eligible voters were exposed to a positive or negative campaign by an opponent. The survey experiment used on-line videos and slogans. The field experiment used door-to-door canvassing. In both experiments, gender differences emerge. Females vote more for the opponent and less for the incumbent when exposed to positive—as opposed to negative—campaigning. Males do the opposite. These differences cannot be explained by gender identification, ideology, or other voters’ observable attributes.

'I cannot accept it' distressing experiences in parents of children diagnosed with cancer: A qualitative study.

To explore the distressing experiences of Chinese parents of children with cancer from the perspective of psychological inflexibility. A qualitative study using a descriptive qualitative approach based on the model of psychological inflexibility was adopted. Individual semi-structured interviews through synchronized online video were conducted with 21 Chinese parents of children with cancer from October 2020 to May 2021. Data were analysed using content analysis. Four themes and 11 subthemes were identified: (i) immersion in struggling and suffering, (ii) avoidance and suppression, (iii) blaming and complaint and (iv) helplessness and worthlessness. Parents were unwilling to accept the diagnosis and witness their children's suffering, trapped in uncontrollable negative emotions and thoughts. Avoiding emotions and socializing, blaming themselves or complaining of injustice were common. They felt helpless towards life and valueless without the child. The research findings provide additional perspectives in understanding the distressing experiences in parents of children with cancer. Overall, the emotional and coping styles indicated the lack of psychological flexibility of parents when facing childhood cancer, which is profoundly influenced by Chinese culture. Healthcare professionals are recommended to provide culturally sensitive strategies or interventions for building psychological flexibility in addressing parental psychological distress. The study provides insights into exploring distressing experiences and reveals the inflexible psychological and behavioural patterns in parents of children with cancer, which could benefit healthcare providers in managing parental psychological distress and helping these parents build flexible coping strategies. The COREQ guideline was followed. No patient or public involvement.

Link between Wi-Fi, cordless devices, mobile phone usage patterns, and behavioral problems among Japanese children: A prospective cohort study

BackgroundWith the recent advent of technology, it is important to confirm the health and safety of the youth. This study aimed to prospectively evaluate the relationship between Wi-Fi, cordless phones, and mobile phone usage patterns and behavioral problems. MethodsThis study involved 2465 children aged 8–17 years from the Hokkaido Study on Environment and Children’s Health from October 2020 to January 2021, with a follow-up from September 2021 to March 2022. The mother–child dyad provided information on the presence of residential Wi-Fi and cordless phones, cordless phone call duration, and mobile phone usage pattern (duration of calls using mobile network and internet, online audio streaming, online video streaming, and playing online games) via a baseline questionnaire. Based on the scores on Strength and Difficulties Questionnaire at baseline and follow-up, the children were categorized into four groups: normal, persistent, improved, and concurrent. ResultsNo significant association was found between Wi-Fi, mobile phone calls via mobile networks, and behavioral problems. Cordless phone at home had higher odds for improvement in total difficulty scores, and cordless phone for calling more than 4 min per week had lower odds of persistent problematic prosocial behavior. Longer duration of mobile phone calling via the internet (>40 min/week) had higher odds of concurrent total difficulties. Mobile phone calling via mobile network for <5 min per week had higher odds for improved total difficulty scores. Audio streaming via mobile phones for 60–120 min had lower odds of persistent total difficulties. ConclusionOur results showed sporadic findings between residential RF-EMF indoor sources and mobile phone usage pattern. These observed findings could be affected by residual confounding and chance findings. Ongoing follow-up studies are necessary to further explore this association through detailed exposure assessment and addressing the potential limitations of our study.

Factors Influencing the Self-Management Stages of Older Patients With Chronic Pain: A Cross-Sectional Study

PurposeTo investigate the current status and related influencing factors of self-management stages in older patients with chronic pain. DesignA cross-sectional study. MethodsA total of 326 older patients with chronic pain were selected as the study subjects in five city districts from December 2022 to June 2023. We used a general information survey form, a numerical rating scale, a pain stages of change questionnaire, a health literacy assessment instrument for patients with chronic pain, and a psychological inflexibility in pain scale to collect relevant information from participants. Univariate analysis and multiple ordinal logistic regression analysis were conducted to identify the relevant influencing factors of the self-management stages. ResultsThe self-management stages of older patients with chronic pain were as follows: precontemplation stage (n = 52; 16.0%), contemplation stage (n = 103; 31.6%), action stage (n = 62; 19.0%), and maintenance stage (n = 109; 33.4%). Regression results showed that average monthly household income, smoking history, pain duration, health literacy, and psychological inflexibility were the influencing factors for the self-management stages of older patients with chronic pain. ConclusionsIn this study, the self-management stages of older patients with chronic pain still needed to be improved. Suitable personalized pain self-management strategies should be developed based on identified factors affecting patients to improve their self-management stages. Clinical ImplicationsNursing professionals can use research survey findings to identify patients at low levels of self-management stage and develop personalized intervention strategies based on various influencing factors. For example, nurses can provide practical smoking cessation guidance to assist older chronic pain patients in improving their lifestyle. Nurses can also seek support from family members to collectively offer better medical care and nursing services for the patient if financially feasible. Secondly, as our study has demonstrated, patients' health literacy and psychological flexibility were poor. Nurses can utilize available clinical resources to offer educational materials, such as portable handbooks and online videos, covering pain-related knowledge, managing pain medication, and coping strategies like massage and exercise. Combining this approach with mental health education, such as relaxation therapy, can help patients better understand their pain and actively participate in their self-management. In addition, nursing staff should pay more attention to the self-management stages of older chronic pain patients, and the assessment of self-management stages can be included in clinical pain management for patients. Regular assessment will help track more patients needing attention and make timely adjustments to their pain management plans.

Live birth after transmyometrial embryo transfer in a patient with radical trachelectomy

ObjectiveTo report the successful utilization of transmyometrial embryo transfer (TMET) in a patient with a history of radical trachelectomy. DesignVideo article. SettingAcademic fertility center. Subject(s)A 39-year-old, para 1, woman with a history of radical trachelectomy and abdominal cerclage presented with secondary infertility. Her prior pregnancy was conceived naturally. Her first in vitro fertilization (IVF) cycle yielded only one day-7 euploid blastocyst. All attempts at performing mock embryo transfers, cervical dilatation and hysteroscopy were unsuccessful due to absence of clinically identifiable cervical tissue. The euploid embryo was transferred into a gestational carrier; however, this resulted in a biochemical pregnancy. She underwent a second IVF cycle that yielded one day-5 euploid blastocyst. Given her history, TMET was planned. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. InterventionTMET using the Towako® catheter. Main Outcome MeasuresImplantation, clinical pregnancy and live birth. ResultsFollowing institutional and Health Canada approval of the Towako® catheter, a transvaginal-ultrasound guided TMET was performed under sedation with intravenous midazolam and fentanyl. The day-5 euploid blastocyst from the second IVF cycle was transferred and the patient’s β-human chorionic gonadotropin (β-hCG) levels 9 and 11 days after TMET were 86 IU/L and 262 IU/L, respectively. A single intrauterine pregnancy with cardiac activity of 119 beats/min was noted at a gestational age of 7 weeks and 2 days. The patient delivered a live singleton at 35 weeks and 2 days weighing 2182 grams. ConclusionTMET is a useful clinical technique for transferring embryos in patients with acquired or congenital cervical issues in whom trans-cervical embryo transfer is either very difficult or impossible.

The purpose of this study is to design a Kalimba ensemble teaching plan based on the direction and digital application of the 2022 revised curriculum, and to suggest ways to effectively fulfill the goals of the 2022 revised curriculum in the school setting. The theoretical backgrounds of the Kalimba and the Metaverse were gathered through a review of academic papers and dissertations. The performance domain of the 2022 revised music curriculum was analyzed to design a teaching plan and explore practical methods for implementing a digital-instrument integrated class, as intended by the revised curriculum. The digital elements and music performance classes emphasized in the 2022 revised curriculum were fused so that students could experience the basics of new technologies. To create a student-led participatory class, a virtual reality space and study score were produced directly, enabling students to engage in creative and self-directed learning. To complement this, this study creates a virtual reality space using the Metaverse platform "ZEP" and provides online video and ensemble performance forms using the video link connection function of "ZEP" to foster basic digital literacy and improve music performance. It is hoped that research on instrumental teaching methods using digital media will be further expanded so that students can recognize the sensibility and value of music.

Do Student Perceptions of Teaching Vary by Faculty Rank?

In this study we measured the degree to which undergraduate students are aware of differences in tenure-track and adjunct faculty roles and responsibilities, and tested if student perceptions of teaching effectiveness vary based on faculty position type. We randomly assigned undergraduate students (N = 214) to read an instructor profile identifying the teacher as either a tenure-track faculty or adjunct instructor. Students then watched an online video lecture and rated the instructor’s teaching effectiveness, perceived effort, and their own likelihood to take the instructor’s class. We used analyses of variance and found that students rated the instructor the same in both conditions regardless of perceived position, but students were able to distinguish differences in faculty rank roles and responsibilities, suggesting students have a basic understanding of the roles and responsibilities of tenure-track and adjunct instructors.

Immediate Versus Delayed Low-Stakes Questioning: Encouraging the Testing Effect Through Embedded Video Questions to Support Students’ Knowledge Outcomes, Self-Regulation, and Critical Thinking

AbstractIn light of the educational challenges brought about by the COVID-19 pandemic, there is a growing need to bolster online science teaching and learning by incorporating evidence-based pedagogical principles of Learning Experience Design (LXD). As a response to this, we conducted a quasi-experimental, design-based research study involving nN = 183 undergraduate students enrolled across two online classes in an upper-division course on Ecology and Evolutionary Biology at a large R1 public university. The study extended over a period of 10 weeks, during which half of the students encountered low-stakes questions immediately embedded within the video player, while the remaining half received the same low-stakes questions after viewing all the instructional videos within the unit. Consequently, this study experimentally manipulated the timing of the questions across the two class conditions. These questions functioned as opportunities for low-stakes content practice and retention, designed to encourage learners to experience testing effect and augment the formation of their conceptual understanding. Across both conditions, we assessed potential differences in total weekly quiz grades, page views, and course participation among students who encountered embedded video questions. We also assessed students’ self-report engagement, self-regulation, and critical thinking. On average, the outcomes indicated that learners exposed to immediate low-stakes questioning exhibited notably superior summative quiz scores, increased page views, and enhanced participation in the course. Additionally, those who experienced immediate questioning demonstrated heightened levels of online engagement, self-regulation, and critical thinking. Moreover, our analysis delved into the intricate interplay between treatment conditions, learners’ self-regulation, critical thinking, and quiz grades through a multiple regression model. Notably, the interaction between those in the immediate questioning condition and self-regulation emerged as a significant factor, suggesting that the influence of immediate questioning on quiz grades varies based on learners’ self-regulation abilities. Collectively, these findings highlight the substantial positive effects of immediate questioning of online video lectures on both academic performance and cognitive skills within an online learning context. This discussion delves into the potential implications for institutions to continually refine their approach in order to effectively promote successful online science teaching and learning, drawing from the foundations of pedagogical learning experience design paradigms and the testing effect model.

Surveillance and self-care: Performing beauty labor in online video content

Beauty labor, practices that are aimed at attaining, optimizing or shaping physical appearances, has been a part of ‘doing girl’ for decades. But new technologies and neoliberal sensibilities are changing the ways in which beauty is presented to girls and women. This qualitative research examines the discourse of 22 YouTube beauty videos. Using a multimodal critical discourse analysis, this project concerns the mechanisms through which influencers construct themselves as neoliberal subjects and convey this identity to their audiences, subsequently selling the idea of aesthetic entrepreneurialism through the object of the self. It is found that beauty videos contain new and intensified two-way surveilling gazes under which women perform their beauty labor. These gazes influence both the audience and the audienced, as both are subject to possible constant evaluation. YouTubers criticized or praised the looks, behavior or beauty practices of other women, but also adjusted their own behavior and beauty practices based on audience’s critiques. Ideas of beauty labor as a personal responsibility and as a tool for self-optimizing are also found within data. Videos contain notions of neoliberal sensibilities, with YouTubers emphasizing the malleability of their face, the efficiency of their practices, the pricelessness of their labor and the fun of their beauty practices.

Pornographic video detection based on semantic and image enhancement

Abstract Pornographic video detection is of significant importance in curbing the proliferation of pornographic information on online video platforms. However, existing works often employ generic frame extraction methods that ignore the low-latency requirements of detection scenarios and the characteristics of pornographic videos. Additionally, existing detection methods have difficulties in detail characterization and semantic understanding, resulting in low accuracy. Therefore, this paper proposes an efficient pornographic video detection framework based on semantic and image enhancement. Firstly, a keyframe extraction method tailored for pornographic video detection is proposed to select representative frames. Secondly, a light enhancement method is introduced to facilitate accurate capture of pornographic visual cues. Moreover, a compression-reconstruction network is employed to eliminate adversarial perturbations, enabling models to obtain reliable features. Subsequently, YOLOv5 is introduced to locate and crop human targets in keyframes, reducing background interference and enhancing the expression of human semantic information. Finally, MobileNetV3 is employed to determine if the human targets contain pornographic content. The proposed framework is validated on the publicly available NPDI dataset, achieving an accuracy of 95.9%, surpassing existing baseline methods.

Legal nature of the metaverse

Representing a network of virtual worlds, the metaverse ultimately forms a complex object of legal regulation due to the possibility of its normalization according to the provisions of different branches of law. The present work sets out to reveal the legal nature of the metaverse from a legal perspective. The selected methodology for determining its legal nature consists in comparing objects that are similar to the metaverse, but are already regulated by legal provisions. Such objects include the Internet, websites, multiplayer online video games, and virtual space in general. In order to identify their similarities and differences, the metaverse is compared to the specified objects. While the multifaceted nature of the metaverse permits its definition from a Russian legal perspective as information, as an object of intellectual property, or as a means of communication, the metaverse resembles the compared objects only in the most general way, while their differences are so significant that reducing its legal nature to only one of them does not fully account for its salient characteristics. By analogy with other spatial categories, but taking into account its specific features, the metaverse can be considered as a virtual space sui generis. While there is a lack of current legal regulation to support such a conclusion, future legislation of the metaverse should be built with this in mind.

Evaluation on Digital Online Videos-Project of Algebra Material

It's a challenges to learn algebra at the faculty of informatics in Sorong, Papua Barat, Indonesia. This suggested learning materials that were engaging and interactive and focused on practical skills. Algebra courses at times assign online digital video projects as a learning strategy. In this study, the skills of students in video-projects along with additional online, digital assignments pertaining to algebra were observed, examined, and determined. The ICSDR (Identify, Conceptualize/Connect, Storyboard, Develop, Review/Reflect, and Refine) methodology was utilized as the framework for a digital online video production. The ICSDR methodology makes algebraic content interactive for education and helps students in understanding the idea of online digital video projects. This study employed a hybrid approach, including project-based learning , descriptive theoretical-practical evaluation, and subjectively analysis. As a result, students are passionate about using applications for producing movies and working on assignments such as online digital video projects. This increased skills and experience in terms of video processing and video editing. Results from the subjective video evaluation were fairly good in terms of concepts, creativities, theories, and problem solving as practice questions.
