User discontinuance on short-video platform has become increasingly prevalent in recent years. Short-video discontinuance refers to reduced use, controlled use or suspended use of the short-video platform. In this study, we examined factors associated with discontinuance behavior on short-video platform.

From the perspective of stressor–strain–outcome (SSO), we put forward a theoretical model integrating perceived information overload and perceived system feature overload (stressors), dissatisfaction (psychological strain), flow experience and regret to explain discontinuance behavior on short-video platform (behavioral outcome). We collected 482 survey data from Douyin users in China, and empirically examined the proposed research model via Partial least squares structural equation modeling (PLS-SEM) technique.

Our results demonstrated that perceived system feature overload exerts a positive effect on perceived information overload. Perceived system feature overload has a stronger influence on dissatisfaction than perceived information overload. Regret increases user dissatisfaction, while flow experience decreases user dissatisfaction. We also discovered that dissatisfaction and regret have significant positive effects on discontinuance behavior. Interestingly, flow exerts no significant influence on discontinuance behavior.

This study enriches the body of knowledge on social media discontinuance by revealing the interaction and effects of flow experience, dissatisfaction and regret on discontinuance. This study also extends the understanding on the complex role of flow experience in leading to social media discontinuance. Additionally, this study deepens the research on the interaction between perceived system feature overload and perceived information overload as well as their different influences on negative emotion.

This paper investigates the interaction effect of audio and video, and studies lip synchronization (lip sync). The study shows a comprehensive evaluation of achievable audio and video quality undertaken based upon different sets of impairments between audio and video, prior to transmission. The tests have been conducted on two different task scenarios, i.e. passive communication and interactive communication (person to person). The research concentrates on quantifying the effects of network impairments (packet loss) on perceived audio and video quality, as well as finding the correlations between audio and video in multimedia applications. The results presented in this paper show the strong interaction dependency between audio and video. It was justified that video has a unique benefit on multimedia quality for its psychological effects. The findings also concluded that the sensory interactions, and the attention given to a particular aspect of performance, are clearly content‐dependent.

The purpose of this paper is to explore the availability and features of Latin American and Spanish online videos available through video vendors and other providers to US academic libraries.

The paper examines US, Spanish, and Latin American video vendors that offer online videos about and/or are produced in Latin America and Spain. The study focuses on: content, technical aspects, and terms of purchase. For video vendors providing digital delivery systems, searching capabilities and special features are also analyzed. The paper also evaluates video providers interested in working with academic libraries. The availability of videos integrated in major multimedia databases is also explored.

The paper concludes that the Spanish and Latin American online video marketplace for academic libraries is still emerging, especially for those video vendors located abroad. The relatively small number of offerings are mostly documentaries. Streaming via internet protocol access is the most common way of delivery. Term licenses are standard and access is allowed both off‐campus and on‐campus.

Little research has been done on the availability of Latin American and Spanish online videos. This research would be especially useful for librarians responsible for collection development in these subject areas.

Video is an increasingly important medium for the communication of ideas in academia. It has high potential as a tool in instruction and is valuable for the visual portrayal of the outcomes of large‐scale mathematical models and simulations. A major problem for conventional video is that it is a passive medium, moving linearly at a fixed pace regardless of the viewer. This problem is overcome when video documents are made interactive so that the viewer can affect the pace and order of viewing. Video controlled by computer software permits the user to select video segments for viewing in any order and see video segments in the context of text, computer graphics, and sound. In effect, one can read a book (on screen) where the photographs are video segments, and one can branch from any page to any other as interest dictates. We might call such materials compound documents and the method of delivering them a multimedia presentation. Libraries have begun to collect interactive video materials and to sustain the equipment necessary to make the documents useful to readers. The challenge to library managers is making sensible decisions about investments in this arena.

The purpose of this paper is to describe and assess Arabic videos related to cancer treatment to gain insights about the nature of health information as it is shared on YouTube. Accordingly, future strategies for different bodies are suggested to promote effective communication.

The approach is to select a representative sample of YouTube videos for certain search terms related to cancer treatment in the Arabic language. In order to identify the search terms, Google Trends is utilized. To retrieve the most relevant videos, a simple python tool is developed using YouTube API V3. For this study, the first 150 relevant videos are quantitatively and qualitatively analyzed. Objective data and subjective data are collected for each video and analyzed. Objective data include video title, URL, length, view count, like count, dislike count, comment count and the associated tags. For content analysis, coding themes are defined for the subjective data as follows: video format, video authorship and video content. Video content includes three categories: types of treatments, targeted part and evidence-based indicators.

The study included 150 videos, from which 30 videos were not content related; therefore, 120 videos remain in the analysis. Using rounding values, it can be observed that the average video lasted 10 min, had 184,966 views, was commented on 263 times, was liked by 2,295 users and disliked by 148 users. Non-professional individuals (46 percent) posted less than half of the videos, whereas public institutions posted only 18 percent of videos. More than half of videos (56 percent) promoted using herbal, botanical, and other natural products for cancer treatment. The majority of YouTube video formats were videos (52 percent), followed by audio with captions (30 percent). News and stories were the dominant videos, with (16 percent), and other types of videos were mostly testimonials and private centers promotions. Only 6 and 9 percent of videos targeted the genetic and immune systems, respectively. Out of the 120 analyzed videos, 86 percent did not mention any risk factor for the recommended treatment, and 73 percent did not offer the details of their usage direction.

Researchers need to understand the information that is currently available on social media platforms related to the high-risk diseases in order to design initiatives, tools, and actions to allow an easy effective transfer of knowledge.

Recounting in-depth knowledge of YouTube cancer treatment contents will allow policy makers, YouTube management, medical organizations, and government agencies to understand the viewers’ behavior of YouTube and their needs to provide accurate and trustworthy information to adopt evidence-based resources.

Creating the suitable content, in terms of health promotion strategies, associated with the appropriate format and understandable language that people need will be one of the major responsibilities of YouTube management, government and professional bodies. The well-designed health messages will enhance users’ engagement and attention to health issues from trusted sources.

There is very less information about Arabic messages in social media, YouTube in particular, specifically regarding cancer treatment. Thus, this study is one of the first studies to explore how Arabic messages are presented on YouTube. The aim of the assessment is to extract the current status and suggest future strategies for different bodies to have effective communication toward the Arabic communities.

The high-efficient processing of mass data is a primary issue in building and maintaining security video surveillance system. This paper aims to focus on the architecture of security video surveillance system, which was based on Hadoop parallel processing technology in big data environment.

A hardware framework of security video surveillance network cascaded system (SVSNCS) was constructed on the basis of Internet of Things, network cascade technology and Hadoop platform. Then, the architecture model of SVSNCS was proposed using the Hadoop and big data processing platform.

Finally, we suggested the procedure of video processing according to the cascade network characteristics.

Our paper, which focused on the architecture of security video surveillance system in big data environment on the basis of Hadoop parallel processing technology, provided high-quality video surveillance services for security area.

The use of video as a teaching and learning aid in education and training is a relatively recent development. Yet already its effectiveness can be demonstrated in many areas. For many, the first contact with video is in the home. Here it is typically used as a means of time‐shifting television programmes: that is, recording them at the time of transmission in order to view them at a more convenient time. A further popular use of the home video recorder is to view tapes purchased or rented from shops and video clubs. These cover a variety of topics, some educational in content.

NO better indication of the growing consumer interest in video systems in Britain exists than the number of monthly magazines available on the subject. Excluding journals such as Audio visual and Video which cater mainly for the professional, there are at the time of writing six periodicals dealing with domestic video: Popular video (formerly Music and video), Television and home video, Video review, Video today, Video world and What video? (As a further sign of the times, the established magazine Photoplay has been transformed into Photoplay movies and video, with front cover emphasis on the last three words of the title). By way of contrast, there is only one comparable journal devoted to amateur film making, Movie making having taken over its competitor Film making in late 1980. Movie maker itself has ackowledged the importance of home video by carrying a regular video column and advertisements. The various publishing groups are as follows:

The power of television in modern society is beyond dispute. The ability of television and video to captivate an audience and create maximum impact can easily be harnessed for training and teaching. Instructors will find that video ‐ when used properly ‐ will enhance virtually any presentation. Video in training and teaching must be used carefully and considerable thought and preparation is needed. This paper presents ideas and information on different types of video material, including their sources and most effective use. It concludes with notes on copyright to help ensure your presentation is both successful and legal.

This paper reports on a project in which students watched short instructional videos on aspects of academic writing as part of a ‘flipped classroom’ approach at an English-medium university in the United Arab Emirates. The authors present the video tutorial project in the context of the flipped classroom, and evaluate student satisfaction with the video input. The findings suggest that although most students liked watching the videos at home, and found the input easy to understand, they still felt the need for teacher explanations. One conclusion from this study is that students are not yet ready for a complete flipped classroom in which all the input is given through the video. In this context, a mix of video input and teacher explanation is more appropriate.
