Science, technology, engineering, and mathematics undergraduates’ knowledge and interest in quantum careers: Barriers and opportunities to building a diverse quantum workforce

Efforts to build the workforce in support of the second quantum revolution are growing, including the creation of education programs that will prepare students for jobs in this area. We surveyed 186 undergraduate students with majors across the science, technology, engineering, and math (STEM) disciplines and followed up with group interviews to understand their perspectives. The project was designed to understand what these STEM students know about quantum and quantum career opportunities and their level of interest in pursuing a career related to quantum. We found that most of the students know very little about quantum. Nevertheless, except for students in the life sciences, there was an interest in quantum careers. Across STEM majors, women were less likely to express interest in quantum careers than men, but this difference disappeared when we examined only physical and computer science majors. Of the few students who had knowledge of quantum concepts, most learned about this topic from online media, especially online videos. Some students reported learning about quantum in high school classes, where it was taught as an extension beyond the usual topics of the course. The undergraduate STEM students in our study identified multiple ways they would like to learn more about quantum, including short videos, seminars, courses, certificates, and degree programs.

Learning to Implement Dialogic Reading Through Video-Based Online Training: A Preliminary Study.

Dialogic reading (DR) is an evidence-based method for reading with young children that is associated with improvements in children's oral language skills. There is, however, a lack of consensus on (a) how to train educators to deliver the intervention and (b) methods for assessing implementation fidelity. We designed this study to provide preliminary data about the viability of online video modules as an initial training option within a future tiered training model. We employed a within-subject repeated-measures group design to evaluate educators' (N = 20) implementation of DR after viewing training videos. Educators filmed themselves reading three storybooks with a child "as they would typically" to establish pretest reading behaviors. After being given access to a series of DR training videos, the educators recorded themselves reading three storybooks with the child using DR strategies as a posttest measure. Educators improved their use of individual strategies included in the DR instructional sequence at posttest; however, most participants did not consistently follow the entire instructional sequence as designed. Only one educator delivered the complete DR instructional sequence in > 80% of opportunities at posttest. Modifications to video training modules and additional coaching support may be warranted for many educators to achieve the level of implementation fidelity needed to improve the child's oral language skills from the intervention. https://doi.org/10.23641/asha.25749387.

Effectiveness and feasibility of 5G-based remote interactive ultrasound training in critical care

BackgroundUltrasound has widely used in various medical fields related to critical care. While online and offline ultrasound trainings are faced by certain challenges, remote ultrasound based on the 5G cloud platform has been gradually adopted in many clinics. However, no study has used the 5G remote ultrasound cloud platform operating system for standardized critical care ultrasound training. This study aimed to evaluate the feasibility and effectiveness of 5G-based remote interactive ultrasound training for standardized diagnosis and treatment in critical care settings.MethodsA 5G-based remote interactive ultrasound training system was constructed, and the course was piloted among critical care physicians. From July 2022 to July 2023, 90 critical care physicians from multiple off-site locations were enrolled and randomly divided into experimental and control groups. The 45 physicians in the experimental group were trained using the 5G-based remote interactive ultrasound training system, while the other 45 in the control group were taught using theoretical online videos. The theoretical and practical ultrasonic capabilities of both groups were evaluated before and after the training sessions, and their levels of satisfaction with the training were assessed as well.ResultsThe total assessment scores for all of the physicians were markedly higher following the training (80.7 ± 11.9) compared to before (42.1 ± 13.4) by a statistically significant margin (P < 0.001). Before participating in the training, the experimental group scored 42.2 ± 12.5 in the critical care ultrasound competency, and the control group scored 41.9 ± 14.3—indicating no significant differences in their assessment scores (P = 0.907). After participating in the training, the experimental group’s assessment scores were 88.4 ± 6.7, which were significantly higher than those of the control group (72.9 ± 10.8; P < 0.001). The satisfaction score of the experimental group was 42.6 ± 2.3, which was also significantly higher than that of the control group (34.7 ± 3.1, P < 0.001).ConclusionThe 5G-based remote interactive ultrasound training system was well-received and effective for critical care. These findings warrant its further promotion and application.

Women's Experiences of Sexual Harassment in Online Gaming.

To better understand the types of sexual harassment women experience in online gaming, their labeling of such experiences, and the relationship between the perpetrator and the victim, we surveyed women gamers to inquire about their experiences. Participants were 182 women from North America who played online video games. Overall, 56.6% of participants reported experiencing one or more types of sexual harassment during online gaming. Additionally, 45.6% of participants reported witnessing one or more types of sexual harassment perpetrated against other women. About half (50.5%) of participants who had experienced harassment labeled their own experiences as "sexual harassment," and 42.2% labeled the behaviors that they witnessed against someone else as "sexual harassment." Results speak to the need for prevention interventions to protect women gamers.

Online dance versus online therapeutic exercise on quality of life - a study protocol for a randomized controlled trial investigating social telerehabilitation efficacy in Parkinson disease

Background Social telerehabilitation delivers rehabilitation services over online video conferencing within a social context. The modality of multimodal therapeutic exercises is the most recommended rehabilitation for individuals with PD, although other modalities, such as dance, have shown potential benefits. The investigation of the feasibility and efficacy of these therapeutic strategies in a remote online format is unknown. Methods This is a prospectively registered two-arm randomised controlled trial investigating the efficacy of online dance compared to online multimodal therapeutic exercise by looking at the biopsychosocial PD aspects. Individuals diagnosed with idiopathic PD between 40 and 90 years old, at any stage of disease severity, and without cognitive impairment will be recruited from the community. Participants will be randomly allocated to one of the two social telerehabilitation groups: (1) dance and music or (2) multimodal therapeutic exercise and music. Interventions will occur twice a week for twelve weeks. Each session will last 60 min. Tele-assessments will be conducted pre-, post-, and one-month follow-up through a videoconference platform. Results For feasibility, primary outcomes will include adherence, attendance, adverse events, and participants’ perceptions of enjoyment and socialisation. For efficacy, primary outcomes will investigate well-being by positive affect (by the Positive Affect and Negative Affect Schedule) and persistent anxiety, episodic anxiety, and avoidance behaviour (by the Parkinson Anxiety Scale). Secondary outcomes will include motor severity (by the UPDRS III), functional lower extremity strength (by the Five Times Sit to Stand Test), memory and attention (by the Attention and Recognition Memory Test), and quality of life (by the Parkinson’s Disease Questionnaire 39). Conclusion We hypothesise that both interventions would effectively ameliorate motor symptoms. However, we expect dance to be more enjoyable and improve well-being by increasing positive affect and reducing anxiety signs.

InteractNet: Social Interaction Recognition for Semantic-rich Videos

The overwhelming surge of online video platforms has raised an urgent need for social interaction recognition techniques. Compared with simple short-term actions, long-term social interactions in semantic-rich videos could reflect more complicated semantics like character relationships or emotions, which will better support various downstream applications, e.g., story summarization and fine-grained clip retrieval. However, considering the longer duration of social interactions with severe mutual overlap, involving multiple characters, dynamic scenes and multi-modal cues, among other factors, traditional solutions for short-term action recognition may probably fail in this task. To address these challenges, in this paper, we propose a hierarchical graph-based system, named InteractNet, to recognize social interactions in a multi-modal perspective. Specifically, our approach first generates a semantic graph for each sampled frame with integrating multi-modal cues, and then learns the node representations as short-term interaction patterns via an adapted GCN module. Along this line, global interaction representations are accumulated through a sub-clip identification module, effectively filtering out irrelevant information and resolving temporal overlaps between interactions. In the end, the association among simultaneous interactions will be captured and modelled by constructing a global-level character-pair graph to predict the final social interactions. Comprehensive experiments on publicly available datasets demonstrate the effectiveness of our approach compared with state-of-the-art baseline methods.

Metaverse decline, growth in online videos increases: implications to libraries

Purpose This paper aims to explore the decline of the metaverse and the concurrent growth of online videos, examining their implications for libraries. It analyzes factors contributing to the metaverse decline, such as technical issues and privacy concerns, and explores the emergence and popularity of online video platforms. Design/methodology/approach This study applied the interpretive content/document analysis of literature harvested from different databases of Scopus, Web of Science and Directory of Open Access Journals. Given the shift in digital consumption patterns and their impact on libraries, the paper systematically reviews the literature to elucidate the changing landscape of digital engagement and its implications for library services and outreach efforts. Findings The paper identifies technical issues, privacy concerns and a lack of interoperability as key factors contributing to the decline of the metaverse. Conversely, the growth of online videos is driven by the emergence of platforms, increasing accessibility to high-speed internet and a diversification of content offerings. These trends reshape user preferences and behaviors, presenting both challenges and opportunities for libraries. Originality/value The decline of the metaverse and the rise of online videos underscore the importance of adaptation and innovation for libraries. To remain relevant in the digital age, libraries must transform their services to meet the demand for on-demand content and multimedia resources. The findings highlight the need for libraries to invest in digital literacy and media literacy programs, embrace emerging technologies and forge strategic partnerships with online video platforms. By adapting to changing trends and user preferences, libraries will continue to fulfill their mission of providing access to information and knowledge in the digital age.

“Did I do the right thing?” Nurses' experiences of caring for victims of child maltreatment: A qualitative study

PurposeThe purpose of this study is to explore and gain insight into pediatric nurses' lived experiences in caring for children who experienced maltreatment. Design and methodA qualitative descriptive phenomenological approach using Giorgi's method was used to support the inquiry of this study. Participants were recruited through the Society of Pediatric Nurses (SPN) and the International Association of Forensic Nursing (IAFN). To collect data, the research team conducted semi-structured interviews individually with each participant online via online video conferencing. ResultsA total of 21 nurses participated in the study. In the final analysis of data, six meaning units are found: (1) helplessly watching children relive the traumatizing events, (2) lack of knowledge and training on caring for children who experienced maltreatment, (3) adversarial relationship and resentment towards parents, (4) conflicting emotions and feelings, (5) long-lasting effects of trauma, and (6) feelings of isolation and loneliness. ConclusionsPediatric and forensic nurses' experiences of caring for children who experienced maltreatment were highlighted by the fact that they lacked the knowledge of caring for these children and felt isolated. Practice implicationsImplementing simulation training on nurses' knowledge and confidence in caring for children who experienced maltreatment is a paramount of importance. This in turn may improve nurses' sense of belonging and enhance the quality of care victims receive.

Exploration of factors affecting webcam-based automated gaze coding.

Online experiments have been transforming the field of behavioral research, enabling researchers to increase sample sizes, access diverse populations, lower the costs of data collection, and promote reproducibility. The field of developmental psychology increasingly exploits such online testing approaches. Since infants cannot give explicit behavioral responses, one key outcome measure is infants' gaze behavior. In the absence of automated eyetrackers in participants' homes, automatic gaze classification from webcam data would make it possible to avoid painstaking manual coding. However, the lack of a controlled experimental environment may lead to various noise factors impeding automatic face detection or gaze classification. We created an adult webcam dataset that systematically reproduced noise factors from infant webcam studies which might affect automated gaze coding accuracy. We varied participants' left-right offset, distance to the camera, facial rotation, and the direction of the lighting source. Running two state-of-the-art classification algorithms (iCatcher+ and OWLET) revealed that facial detection performance was particularly affected by the lighting source, while gaze coding accuracy was consistently affected by the distance to the camera and lighting source. Morphing participants' faces to be unidentifiable did not generally affect the results, suggesting facial anonymization could be used when making online video data publicly available, for purposes of further study and transparency. Our findings will guide improving study design for infant and adult participants during online experiments. Moreover, training algorithms using our dataset will allow researchers to improve robustness and allow developmental psychologists to leverage online testing more efficiently.

Lateral Ankle Joint Injuries in Indoor and Court Sports: A Systematic Video Analysis of 445 Nonconsecutive Case Series

Background: Lateral ankle sprains are one of the most common injuries in indoor and court sports. Self-reports and case studies have indicated that these injuries occur via both contact and noncontact injury mechanisms typically because of excessive inversion in combination with plantarflexion and adduction of the foot. Video-based documentation of the injury mechanism exists, but the number of cases reported in the literature is limited. Purpose: To retrieve and systematically analyze a large number of video-recorded lateral ankle injuries from indoor and court sports, as well as describe the injury mechanism, injury motion, and injury pattern across different sports. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 445 unique video-recorded lateral ankle sprain injuries were retrieved from indoor and court sports of broadcasted levels of competition. The videos were independently analyzed by 2 different reviewers. Outcomes included classification of the injury mechanism according to the International Olympic Committee consensus guidelines, primary and secondary motions of ankle joint distortion, and documentation of the fixation point (fulcrum) around which the foot rotates. Results: Overall, 298 (67%) injuries were direct contact, 113 (25%) were noncontact, and 32 (7%) were indirect contact incidents. Direct contact injuries were especially prevalent in basketball (76%), handball (80%), and volleyball (85%), while noncontact injuries dominated in tennis and badminton (96% vs 95% across both). Inversion (65%) and internal rotation (33%) were the primary distortion motions, with the lateral forefoot (53%) and lateral midfoot (40%) serving as the main fulcrums. Landing on another player's foot was the leading cause of injury (n = 246; 55%), primarily characterized by inversion (79%) around a midfoot fulcrum (54%). The noncontact and indirect landings on floor (n = 144; 33%) were primarily characterized by a distortion around a forefoot fulcrum (69%). Conclusion: Two of 3 ankle sprains from online video platforms were direct contact injuries, with most involving landing on another player's foot. The distortion motion seems to be related to the injury mechanism and the fixation point between the foot and the floor. The injury mechanisms varied greatly between sports, and future studies should clearly differentiate and investigate the specific injury mechanisms.

Towards definitive categories for online video game money laundering

Purpose This paper aims to investigate how best to classify money laundering through online video games (i.e. virtual laundering). Currently, there is no taxonomy available for scholars and practitioners to refer to when discussing money laundering through online video games. Without a well-defined taxonomy it becomes difficult to reason through, formulate and implement effective regulatory measures, policies and security controls. As such, efforts to prevent and reduce virtual laundering incidence rates are hampered. Design/methodology/approach This paper proposes three mutually exclusive virtual laundering categorizations. However, instead of fixating on the processes undergirding individual instances of virtual laundering, it is argued that focusing on the initial locale of the illicit proceeds provides the appropriate framing within which to classify instances of virtual laundering. Thus, the act of classification becomes an ontological endeavour, rather than an attempt at elucidating an inherently varied process (as is common of the placement, layering and integration model). Findings A taxonomy is proposed that details three core virtual laundering processes. It is demonstrated how different virtual laundering categories have varied levels of associated risk, and thus, demand unique interventions. Originality/value To the best of the authors’ knowledge, this is the first taxonomy available in the knowledge base that systematically classifies instances of virtual laundering. The taxonomy is available for scholars and practitioners to use and apply when discussing how to regulate and formulate legislation, policies and appropriate security controls.

Analysis of Tokyo 2020 Olympic modern pentathlon equestrian jumping results

Modern Pentathlon (MP) includes an equestrian Jumping discipline, with horses drawn blindly by unfamiliar riders. At the Tokyo 2020 Olympic Summer Games, concerns regarding inadequate horsemanship generated adverse publicity for MP. Conventional stadium Jumping in Tokyo provided an opportunity for comparison of the two closest Olympic equestrian Jumping disciplines. The objectives of this study were to complete an objective analysis of the Tokyo MP riding phases, and to test the hypothesis that MP riding faults in women's and men's Tokyo competitions combined were more frequent than in the Individual Jumping Qualifier (JQ). Types of faults for Tokyo MP (n = 71 riders) and JQ (n = 73 riders) were tabulated from published official results and detailed observation of online videos of each competition. Fault distributions were compared using Chi-square analysis (significance at P < .05). MP riders had more jumping faults (15.4 %) than JQ (7.8 %, P < .0001). Both MP and JQ riders had more faults at oxers (17.1 %, P < .0001 and 9.7 %, P = .0171, respectively) than verticals (14.5 % and 6.2 %). JQ (9.8 %, P = .0093) but not MP (15.7 %, p = .5166) riders had more faults in the second half of the course compared to the first half (5.7 % and 15.0 %, respectively). Double clear rounds (no jumping or time faults) were 4.9 times more likely in JQ (34.2 %) than in MP (6.9 %: P < .0001). Proposed solutions to decrease MP fault frequency include lower maximum fence heights, fewer jumping efforts, and a more liberal re-ride policy.

Legitimizing video-sharing practices on local and global platforms: A multimodal analysis of menu design, folk genres and taxonomy

There have been extensive public and academic debates on the role platform algorithms play in shaping social media (sub)cultures. Little attention, however, has been paid to how platform (sub)cultures are discursively constructed by the design of the platform interface. This study examines Bilibili, a leading Chinese video platform, and investigates how it discursively frames video-sharing culture through platform menu design. We developed a three-level analytical framework that includes: 1) a multimodal social semiotic analysis of Bilibili’s menu design; 2) a contrastive analysis of YouTube’s video menu, and 3) a focused analysis of guichu or kichiku videos (as a linguistic phenomenon, a transcultural practice and a multimodal semiotic artefact). Our findings reveal that Bilibili discursively frames and legitimizes video-sharing practices by establishing a folk taxonomy of video genres and integrating subculture into its menu design. Furthermore, Bilibili controls access to cultural knowledge through explicit (gatekeeping) and implicit (semiotic) measures, in contrast to YouTube’s visual and superficial taxonomy. This study unveils different discursive strategies platforms use to shape unique online video cultures.

Harnessing Open Innovation for Translating Global Languages into Indian Lanuages

Understanding foreign languages can be challenging for individuals living in India's diverse linguistic landscapes. We propose a new technology that utilizes machine translation to address this issue, specifically focusing on speech recognition and synthesis. It aims to convert online video resources into Indian languages by integrating open-source technologies like text-to-speech (TTS), speech-to-text (STT) systems, and FFmpeg library to separate or augment audio and video. We used the whisper model, the application that can read up to 60 different Languages in the form of audio as input, and it transcripts the audio into text with segments of sentences based on timestamps. The sentence-based transcription generated by whisper is then translated into the desired language using Google Cloud translate_v2. Later, Each timestamp was individually converted into audio using the Google Cloud text-to-speech service, ensuring the audio fits inside the length of its respective timestamp. The individual audio segments are then augmented to generate the final audio in the desired language. Finally, the audio is attached to the original video, ensuring video-audio synchronization. The accuracy of the translation was verified by comparing the naturalness of the audio with general spoken language standards. This application benefits visually impaired individuals and those who cannot read text, providing them with a means to acquire knowledge in their native languages.

Characterizing Technology Use and Preferences for Health Communication in South Asian Immigrants With Prediabetes or Diabetes: Cross-Sectional Descriptive Study.

Type 2 diabetes disproportionately affects South Asian subgroups. Lifestyle prevention programs help prevent and manage diabetes; however, there is a need to tailor these programs for mobile health (mHealth). This study examined technology access, current use, and preferences for health communication among South Asian immigrants diagnosed with or at risk for diabetes, overall and by sex. We examined factors associated with interest in receiving diabetes information by (1) text message, (2) online (videos, voice notes, online forums), and (3) none or skipped, adjusting for sociodemographic characteristics and technology access. We used baseline data collected in 2019-2021 from two clinical trials among South Asian immigrants in New York City (NYC), with one trial focused on diabetes prevention and the other focused on diabetes management. Descriptive statistics were used to examine overall and sex-stratified impacts of sociodemographics on technology use. Overall logistic regression was used to examine the preference for diabetes information by text message, online (videos, voice notes, or forums), and no interest/skipped response. The overall sample (N=816) had a mean age of 51.8 years (SD 11.0), and was mostly female (462/816, 56.6%), married (756/816, 92.6%), with below high school education (476/816, 58.3%) and limited English proficiency (731/816, 89.6%). Most participants had a smartphone (611/816, 74.9%) and reported interest in receiving diabetes information via text message (609/816, 74.6%). Compared to male participants, female participants were significantly less likely to own smartphones (317/462, 68.6% vs 294/354, 83.1%) or use social media apps (Viber: 102/462, 22.1% vs 111/354, 31.4%; WhatsApp: 279/462, 60.4% vs 255/354, 72.0%; Facebook: Messenger 72/462, 15.6% vs 150/354, 42.4%). A preference for receiving diabetes information via text messaging was associated with male sex (adjusted odds ratio [AOR] 1.63, 95% CI 1.01-2.55; P=.04), current unemployment (AOR 1.62, 95% CI 1.03-2.53; P=.04), above high school education (AOR 2.17, 95% CI 1.41-3.32; P<.001), and owning a smart device (AOR 3.35, 95% CI 2.17-5.18; P<.001). A preference for videos, voice notes, or online forums was associated with male sex (AOR 2.38, 95% CI 1.59-3.57; P<.001) and ownership of a smart device (AOR 5.19, 95% CI 2.83-9.51; P<.001). No interest/skipping the question was associated with female sex (AOR 2.66, 95% CI 1.55-4.56; P<.001), high school education or below (AOR 2.02, 95% CI 1.22-3.36; P=.01), not being married (AOR 2.26, 95% CI 1.13-4.52; P=.02), current employment (AOR 1.96, 95% CI 1.18-3.29; P=.01), and not owning a smart device (AOR 2.06, 95% CI 2.06-5.44; P<.001). Technology access and social media usage were moderately high in primarily low-income South Asian immigrants in NYC with prediabetes or diabetes. Sex, education, marital status, and employment were associated with interest in mHealth interventions. Additional support to South Asian women may be required when designing and developing mHealth interventions.

Идеология российского феминизма в свете гендерных процессов (анализ феминистского дискурса)

The article delves into Russian feminism from the perspective of an ideological discourse field that has a coer-cive effect on the participants covered by this field. In modern conditions, the leading actor of discourse for-mation is the blogosphere. Analyzing a number of sites and online videos has shown that apologists of Russian intersectional feminism tend to absolutize the constructivist component of social differences between men and women, which allegedly determine the structure and viciousness of gender relations. However, this thesis de-termines the whole logic of feminist discourse. The functional side of Russian feminism is the emphasis on a critical approach to a number of social facts and phenomena, which allows for a more in-depth understanding of their real and potential problems. Feminism’s socio-economic and legal demands adequately reflect the problems at hand. Far less adequate is feminism on the socio-cultural sphere, where aesthetic norms are actu-ally replaced by naturalism, and politically, feminism is a tool of the diffuse influence of the Western political correctness project, aimed at cultural degradation, anomization and fragmentation of Russian society.
