African cinema in the 1960s originated mainly from Francophone countries. It resembled the art cinema of contemporary Europe and relied on support from the French film industry and the French state. ...Beginning in 1969 the biennial Festival panafricain du cinéma et de la télévision de Ouagadougou (FESPACO), held in Burkina Faso, became the major showcase for these films. But since the early 1990s, a new phenomenon has come to dominate the African cinema world: mass-marketed films shot on less expensive video cameras. These "Nollywood" films, so named because many originate in southern Nigeria, are a thriving industry dominating the world of African cinema. Viewing African Cinema in the Twenty-first Century is the first book to bring together a set of essays offering a comparison of these two main African cinema modes. Contributors: Ralph A.

Objective
To assess the content and quality of YouTubeTM videos concerning nasoalveolar molding (NAM).
Design
YouTubeTM was searched for videos containing information relevant to NAM with the 2 ...keywords “nasoalveolar molding,” and “presurgical infant orthopedics.” A total of 24 out of 51 videos were found to be applicable to this study and rated for quality using the Global Quality Scale (GQS). To determine whether the contents of the selected 24 videos were useful or not, a content usefulness index consisting of 8 parameters was created. The videos were classified according to the usefulness index as low or high content videos. Spearman rank correlation analysis, Kolmogorov-Smirnov, Shapiro-Wilk, and Mann-Whitney U-tests were used for statistical analysis.
Results
The mean GQS score of the 24 YouTubeTM videos on NAM was 2.3 ± 0.8, indicating overall poor quality. In terms of information, videos with high content (29.2%) were less in number than low content videos (70.8%). GQS values were found to be significantly higher in the high content group (P < .01). Regarding the source, video, and audio quality values were significantly higher in the expert group compared to the caregiver group (P < .01), whereas the usefulness index did not differ between groups (P > .05). A significant relationship was found between GQS and usefulness index, audio quality, and video quality (P < .001).
Conclusions
YouTube™ videos on NAM were generally inadequate in their content information and poor in quality. Expert videos, showing better audiovisual quality and flow compared to non-expert videos, did not offer higher quality information about NAM considering the usefulness index.
Background: Implementing lifestyle behavior programs in real-world settings challenges researchers. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) has implemented ...and sustained Mothers In Motion (MIM)’s client videos for clients to promote healthy lifestyle behaviors, and train-the-trainer videos, for personnel to enhance motivational interviewing techniques since 2015 and 2016, respectively. This paper describes the implementation processes and the results of client video implementation acceptability by WIC personnel. Methods: To document the implementation process, we applied the Framework for Adaptation and Modifications to Evidence-Based Implementation Strategies (FRAME-IS). To evaluate implementation acceptability, we conducted semi-structured interviews with 15 WIC personnel. A qualitative analysis was conducted to identify the common themes. Results: The facilitators for client video implementation were the inclusion of the target audience and family members addressing daily challenges, easy implementation, and compatibility with daily practice. While videos online facilitated implementation, videos in DVD format could challenge implementation. Conclusions: Future lifestyle intervention programs aimed for future implementation in community settings may consider the inclusion of the target audience and their family members and take into consideration easy implementation and compatibility.
Objectives: Breast self-examination (BSE) is very important to early detect breast cancer in women in addition to imaging methods. The easiest way to access information concerning how to perform this ...examination is undoubtedly the internet, and the most popular platform is YouTube. However, the most important disadvantage of this massive platform is the risk of spreading false information since it cannot be audited. This study aimed to evaluate Turkish videos on BSE on YouTube in terms of quality and content. Methods: On January 17, 2022, a search was conducted on YouTube using the keyword “breast self-examination”, and the first 210 videos presented on the first five pages were obtained. After applying the study criteria, 156 were included in the sample and evaluated by two general surgeons in terms of educational value, content, and upload source. Results: Of the 156 videos, 23 were categorized as useful (14.7%) and 133 as misleading (85.3%). When examined according to the upload source group, universities/professional organizations/non-profit physicians/physicians had the highest rate of misleading videos (96.9%), while stand-alone health information websites had the highest rate of useful videos (24%). There was no significant difference between the upload sources in terms of video length, number of views, content score, or quality score. Conclusions: The number of useful Turkish videos on BSE is very low. Our results indicate the need for more educational and useful videos to be produced, especially by healthcare professionals who use the YouTube platform.
Flight time is the most accurate and frequently used variable when assessing the height of vertical jumps. The purpose of this study was to analyze the validity and reliability of an alternative ...method (i.e., the HSC-Kinovea method) for measuring the flight time and height of vertical jumping using a low-cost high-speed Casio Exilim FH-25 camera (HSC). To this end, 25 subjects performed a total of 125 vertical jumps on an infrared (IR) platform while simultaneously being recorded with a HSC at 240 fps. Subsequently, 2 observers with no experience in video analysis analyzed the 125 videos independently using the open-license Kinovea 0.8.15 software. The flight times obtained were then converted into vertical jump heights, and the intraclass correlation coefficient (ICC), Bland-Altman plot, and Pearson correlation coefficient were calculated for those variables. The results showed a perfect correlation agreement (ICC = 1, p < 0.0001) between both observers' measurements of flight time and jump height and a highly reliable agreement (ICC = 0.997, p < 0.0001) between the observers' measurements of flight time and jump height using the HSC-Kinovea method and those obtained using the IR system, thus explaining 99.5% (p < 0.0001) of the differences (shared variance) obtained using the IR platform. As a result, besides requiring no previous experience in the use of this technology, the HSC-Kinovea method can be considered to provide similarly valid and reliable measurements of flight time and vertical jump height as more expensive equipment (i.e., IR). As such, coaches from many sports could use the HSC-Kinovea method to measure the flight time and height of their athlete's vertical jumps.
Since the mid-1980s, US audiences have watched the majority of movies they see on a video platform, be it VHS, DVD, Blu-ray, Video On Demand, or streaming media. Annual video revenues have exceeded ...box office returns for over twenty-five years. In short, video has become the structuring discourse of US movie culture. Killer Tapes and Shattered Screens examines how prerecorded video reframes the premises and promises of motion picture spectatorship. But instead of offering a history of video technology or reception, Caetlin Benson-Allott analyzes how the movies themselves understand and represent the symbiosis of platform and spectator. Through case studies and close readings that blend industry history with apparatus theory, psychoanalysis with platform studies, and production history with postmodern philosophy, Killer Tapes and Shattered Screens unearths a genealogy of post-cinematic spectatorship in horror movies, thrillers, and other exploitation genres. From Night of the Living Dead (1968) through Paranormal Activity (2009), these movies pursue their spectator from one platform to another, adapting to suit new exhibition norms and cultural concerns in the evolution of the video subject.
In general, academic but not community endoscopists have demonstrated adequate endoscopic differentiation accuracy to make the 'resect and discard' paradigm for diminutive colorectal polyps workable. ...Computer analysis of video could potentially eliminate the obstacle of interobserver variability in endoscopic polyp interpretation and enable widespread acceptance of 'resect and discard'.
We developed an artificial intelligence (AI) model for real-time assessment of endoscopic video images of colorectal polyps. A deep convolutional neural network model was used. Only narrow band imaging video frames were used, split equally between relevant multiclasses. Unaltered videos from routine exams not specifically designed or adapted for AI classification were used to train and validate the model. The model was tested on a separate series of 125 videos of consecutively encountered diminutive polyps that were proven to be adenomas or hyperplastic polyps.
The AI model works with a confidence mechanism and did not generate sufficient confidence to predict the histology of 19 polyps in the test set, representing 15% of the polyps. For the remaining 106 diminutive polyps, the accuracy of the model was 94% (95% CI 86% to 97%), the sensitivity for identification of adenomas was 98% (95% CI 92% to 100%), specificity was 83% (95% CI 67% to 93%), negative predictive value 97% and positive predictive value 90%.
An AI model trained on endoscopic video can differentiate diminutive adenomas from hyperplastic polyps with high accuracy. Additional study of this programme in a live patient clinical trial setting to address resect and discard is planned.
