    BACKGROUND: Despite technological, political and economic progress, Pakistan is still a traditionally patriarchal society, and cultural norms curb women's freedom of socialization, which contributes to poor mental health. The digital technology spaces are rampant with male dominance, and offline cultural behaviours are replicated. Therefore, the current research in Pakistan intends to focus solely on women, their social media uses and the consequent impact on their psychological well-being. Furthermore, the mediation role of social capital is explored, which is linked to women's socialization. In virtual communication, women can expand their connection or remain limited to known people.

    METHODS: An online survey collected 240 responses from women social media users. The questionnaire was divided into demographics, social media use patterns like access, online time, frequency of use, social media uses, online social capital and psychological well-being. The obtained responses were statistically analyzed using Smart PLS.

    RESULTS: Pakistani women use social media extensively; however, their uses are culturally influenced. The women use social media and socialize online but do not openly disclose their personalities and emotions to extend the connection. They seek information only from acquaintances and do not trust newly developed online contacts. Therefore, the mediation role of bonding social capital is significant, referring to the importance of close ties and trust in psychological well-being. Though virtual spaces provide an opportunity for bridging social capital, women use social media for socialization; however, it doesn't contribute to women's psychological well-being.

    CONCLUSION: Despite the higher penetration of digital technologies, cultural power still rules in developing countries like Pakistan. Social media uses are gender- and culturally specific, contributing to psychological well-being and developing social capital. The results from Pakistani society recommend ensuring a secure digital experience for women to get maximum benefits from social media and enhance their psychological well-being.

    To analyze the public opinion related to the employment situation, a combined approach is proposed to study the valuable ideas from social media. Firstly, the popularity of public opinion was analyzed according to the time series from a statistical point of view. Secondly, the feature extraction was carried out on the public opinion information, and the thematic analysis of the employment environment was carried out based on the Latent Dirichlet Allocation model. Thirdly, the Bert model was used to analyze the sentiment classification and trend of the employment-related public opinion data. Finally, the employment public opinion texts in different regions were studied based on the spatial sequence popularity analysis, keyword difference analysis. A case study in China is conducted to verify the effectiveness of proposed combined approach. Results shown that the popularity of employment public opinion reached the highest level in March 2022. Public opinions towards employment situation are negative. There is a specific relationship between the popularity of employment public opinion in different provinces.

    The COVID-19 pandemic presented significant challenges for individuals who experienced stroke and their caregivers. It is essential to understand the factors affecting preventive behavior in these populations. Therefore, the present study examined the factors that influenced COVID-19 preventive behavior and motivation for COVID-19 vaccine uptake among patients with stroke and their caregivers. A cross-sectional study comprising 191 participants (81 patients with stroke and 110 caregivers) was carried out. Participants completed a survey assessing fear of COVID-19, stress, perceived susceptibility, problematic social media use, preventive behaviors, and motivation for vaccine uptake. Statistical analyses included descriptive statistics, Pearson correlations, and multiple linear regressions. Motivation for COVID-19 vaccine uptake was significantly positively correlated with problematic social media use (r = 0.225, P = .002), perceived susceptibility (r = 0.197, P = .008), and fear of COVID-19 (r = 0.179, P = .015), but negatively correlated with stress (r = -0.189, P = .010). Caregivers, compared to patients, showed a lower level of preventive behavior (standardized coefficient = -0.23, P = .017). Furthermore, higher levels of fear were associated with increased preventive behavior (standardized coefficient = 0.22, P = .006), while greater stress correlated with lower preventive behavior (standardized coefficient = -0.38, P social media use, and stress. By using strategies such as targeted education, support, and communication campaigns, healthcare providers and policymakers may be able to enhance the well-being of patients with stroke and their caregivers during future pandemics.

    In recent years, users' privacy concerns and reluctance to use have posed a challenge for the social media and wellbeing of its users. There is a paucity of research on elderly users' negative connotations of social media and the way these connotations contribute to developing passive behaviour towards social media use, which, in turn, affects subjective wellbeing. To address this research vacuum we employed the stressor-strain-outcome (SSO) approach to describe the evolution of passive social media use behaviour from the perspective of communication overload, complexity, and privacy. We conceptualized subjective wellbeing as a combination of three components-negative feelings, positive feelings, and life satisfaction. Negative and positive feelings were used to derive an overall affect balance score that fluctuates between 'unhappiest possible' and 'happiest possible'. The proposed research framework was empirically validated through 399 valid responses from elderly social media users. Our findings reveal that communication overload and complexity raise privacy concerns among social media users, which leads to passive usage of social media. This passive social media use improved the subjective wellbeing favourably by lowering negative feelings and raising positive feelings and life satisfaction. The findings also revealed that respondents' overall affect balance leans towards positive feelings as a consequence of passive social media use. This study contributes to the field of technostress by illuminating how the SSO perspective aid the comprehension of the way passive social media use influences the subjective wellbeing of its users.

    As social media booms, abusive online practices such as hate speech have unfortunately increased as well. As letters are often repeated in words used to construct social media messages, these types of words should be eliminated or reduced in number to enhance the efficacy of hate speech detection. Although multiple models have attempted to normalize out-of-vocabulary (OOV) words with repeated letters, they often fail to determine whether the in-vocabulary (IV) replacement words are correct or incorrect. Therefore, this study developed an improved model for normalizing OOV words with repeated letters by replacing them with correct in-vocabulary (IV) replacement words. The improved normalization model is an unsupervised method that does not require the use of a special dictionary or annotated data. It combines rule-based patterns of words with repeated letters and the SymSpell spelling correction algorithm to remove repeated letters within the words by multiple rules regarding the position of repeated letters in a word, be it at the beginning, middle, or end of the word and the repetition pattern. Two hate speech datasets were then used to assess performance. The proposed normalization model was able to decrease the percentage of OOV words to 8%. Its F1 score was also 9% and 13% higher than the models proposed by two extant studies. Therefore, the proposed normalization model performed better than the benchmark studies in replacing OOV words with the correct IV replacement and improved the performance of the detection model. As such, suitable rule-based patterns can be combined with spelling correction to develop a text normalization model to correctly replace words with repeated letters, which would, in turn, improve hate speech detection in texts.

    PURPOSE OF REVIEW: There is a lack of synthesized evidence on social media-delivered lifestyle interventions for managing and preventing diabetes. This scoping review aims to evaluate recently reported lifestyle interventions delivered on social media for individuals with diabetes and prediabetes.

    RECENT FINDINGS: Twelve studies were included in this review. A team of multidisciplinary healthcare professionals coordinated most interventions, half of which lasted for 6 months, and used a combination of videos, texts, images or audio to deliver the educational materials. The glycosylated hemoglobin (HbA1c) level improved in most of the studies, followed by diabetes self-care and fasting plasma glucose. The dietary intakes were only assessed in two interventions among the individuals with prediabetes and showed promising improvements. This scoping review provides a holistic overview of the recent designs of lifestyle interventions for diabetes management and prevention on social media. This is essential for various healthcare professionals and stakeholders to formulate and implement population-based, cost-effective interventions in combating diabetes using social media.

    Social media and its applications are a part of daily life in Turkey and the rest of the world. In 2022, about 80.7 % of Turkey's population (69.9 million people) spent an average of 8 h daily using the Internet, providing a significant opportunity to encourage and influence tourists' purchase intentions through social media. This study aims to determine the effects of digital marketing and social media on tourist behaviours in Turkey. This study proposes a comprehensive model for the antecedents of tourists' behavioural intentions in their destination selection that can be found in the tourist destination online content (TDOC). The quality and user-friendly accessibility of the online information provides essential clues that influence tourists' behavioural intentions (intention to visit the destination and eWOM). Tourists' level of satisfaction with their first destination visits and the digital marketing interaction channels through which they share their experiences may positively affect their repeat visits/other tourists' behavioural intentions. Therefore, this study investigates the mediator effect of satisfaction and digital marketing interactions on the behavioural intentions of tourists of Eastern origin during their destination selection. Data was collected from 264 structured questionnaires and analyzed using partial least squares structural equation (PLS-SEM) modelling. Findings show that tourists' TDOC perceptions directly affect their behavioural intentions and that tourist satisfaction has a mediator role in the relationship between tourists' TDOC perceptions and behavioural intentions. Also, the results show that satisfaction and digital marketing interactions are important determinants of the intention to visit a tourist destination and eWOM intentions. Understanding tourists' perspectives on destination choice is crucial for policy makers, businesses and marketers as it will help formulate appropriate strategies to increase destination visits. In this respect, it is recommended to develop strategies to encourage tourists to share their experiences and satisfaction levels through digital marketing channels by improving the quality of products and services. Finally, the population of this study is limited to Turkey, and future research can extend this study to countries with different cultures and make new contributions to the related literature.

    Surgical journals use videos for educational and promotional purposes. YouTube is a suitable social media platform for sharing videos of journal content. The Surgery journal experience on YouTube can be used to learn important information on the nature of video content, the measurement of performance, and the benefits and challenges of using YouTube to disseminate journal content. Video content can be created to deliver information and infotainment. The online performance of videos can be measured using various metrics on YouTube Analytics, including content views and engagement metrics. There are several benefits to the use of YouTube videos by surgical journals, including the dissemination of reliable information, language versatility and diversity, open access and portability, increased visibility for authors and journals, and the humanization of the journal interface. However, challenges also need to be overcome, including viewer discretion where graphic content is concerned, copyright protection, limitations of Internet connection bandwidth, algorithmic barriers imposed by YouTube itself, and violations of biomedical ethics.

    PURPOSE: Social media use among oral and maxillofacial surgeons (OMSs) has grown in recent years, serving as an important resource for the dissemination of medical/surgical knowledge, research, education, diplomacy, and advocacy. However, no studies have attempted to characterize the global reach of social media in OMS.

    METHODS: This study examined the profile activity, content performance, and demographic characteristics of followers from a single OMS-related Instagram account. Variables assessed include the total number of followers since the account's inception, profile views over the selected time period, and unique media content posts, as well as likes, comments, saves, impressions, and reach for all media content posts. The top 45 countries, cities, and languages based on each follower's geolocation and user settings were also included.

    RESULTS: There were 9569 followers of which 6208 (64.9%) were listed as public accounts. Of the 6208 followers with public accounts, 2496 (40.2%) were female. The countries with the most followers included the United States (31.7%), India (12.5%), Malaysia (5.3%), Mexico (4.0%), and Pakistan (3.6%). The cities with the most followers included New York, New York (8.9%), Boston, Massachusetts (5.2%), Cairo, Egypt (4.3%), Santiago, Chile (3.7%), and Karachi, Pakistan (3.5%).

    CONCLUSION: OMS-related social media is uniquely positioned to facilitate global collaboration and augment the dissemination of surgical knowledge and expertise. This information is critical in understanding the distribution and demographics of the OMS workforce, trainees, and affiliates around the world.

    Vaccine hesitancy is gaining attention due to the increasing spread of the COVID-19 pandemic in Malaysia. Malaysia is a majority Muslim country and religion has a significant influence on the acceptance or rejection of vaccines. This is clearly seen through the disagreement over the  halal status of vaccines. Social media has become a platform for discussion and dissemination of information and dis-information on vaccines. Thus, it has had a relatively significant influence on vaccine hesitancy among social media users. By analysing tweets from February 2020 to February 2021 using Twitter API, this paper highlights the discussion of COVID-19 vaccines' halal status on Twitter. This study focuses on the analysis of vaccination reluctancy among the Twitter users in Malaysia and found that the most prevalent theme from the discussion is the constructed religious narratives to justify scientifically misleading and false claims concerning vaccination represented on social media. This finding also calls for a deeper understanding of society's constructed knowledge concerning contemporary issues in the digital age on social media.

    Underpinned by integrating self-determination and source credibility theories (SCT), this paper investigates the focal roles of memorable local food experiences (MLX) and travel influencer endorsement (TIE) on revisit intention. A questionnaire was used to collect data from 513 TikTok influencers (individuals who frequently post videos on TikTok and have a large number of followers). A purposive sampling technique is used to collect data from TikTok influencers who create videos about food tourism in Pakistan. SmartPLS 4.4 was used with PLS-SEM. The empirical results suggest a positive and significant linkage of culinary memorable experience factors with MLX. The focal effects of MLX and TIE on revisit intention are significantly positive. Our findings further revealed that MLX partially mediated the linkage of culinary memorable experience factors with revisit intention, while TIE strengthened the positive relationship between MLX and revisit intention. The study's findings influence travel agents, local food providers, and marketing specialists who develop marketing strategies for local food tourism and online trip purchasing.

    INTRODUCTION: The evaluation of the quality of information (QOI) and clarity of information (COI) among oral health-related videos on the video-streaming Web site YouTube is scarce. This study evaluated QOI and COI regarding temporary anchorage devices contained within videos uploaded by dental professionals (DPs) on YouTube.

    METHODS: YouTube videos were systematically acquired with 4 search terms. The top 50 videos per search term by the number of views were stored in a YouTube account. A set of inclusion/exclusion criteria were applied, videos were assessed for viewing characteristics, a 4-point scoring system (0-3) was applied to evaluate QOI in 10 predetermined domains, and a 3-point scoring system (0-2) was applied to evaluate COI. Descriptive statistical analyses and intrarater and interrater reliability tests were performed.

    RESULTS: Strong intrarater and interrater reliability scores were observed. Sixty-three videos from the top 58 most-viewed DPs were viewed 1,395,471 times (range, 414-124,939). Most DPs originated from the United States (20%), and orthodontists (62%) uploaded most of the videos. The mean number of reported domains was 2.03 ± 2.40 (out of 10). The mean overall QOI score per domain was 0.36 ± 0.79 (out of 3). The "Placement of miniscrews" domain scored highest (1.23 ± 0.75). The "Cost of miniscrews placement" domain scored the lowest (0.03 ± 0.25). The mean overall QOI score per DP was 3.59 ± 5.64 (out of 30). The COI in 32 videos was immeasurable, and only 2 avoided using technical words.

    CONCLUSIONS: The QOI related to temporary anchorage devices contained within videos provided by DPs through the YouTube Web site is deficient, particularly in the cost of placement. Orthodontists should be aware of the importance of YouTube as an information resource and ensure that videos related to temporary anchorage devices contain comprehensive and evidence-based information.

    In this study, we investigated the association between perceived sociocultural influences and the 3-month prevalence of disordered weight-control behaviors and lifetime prevalence of cosmetic procedures in four Asian countries, and if these associations were modified by gender. We conducted a cross-sectional online survey in September 2020 among adults ages 18-91 years (N = 5294) in Malaysia, Singapore, Thailand and Hong Kong. The 3-month prevalence of disordered weight control behaviors ranged from 25.2 % (Singapore) to 42.3 % (Malaysia), while the lifetime prevalence of cosmetic procedures ranged from 8.7 % (Singapore) to 21.3 % (Thailand). Participants who perceived their body image to be influenced by sociocultural factors were more likely to engage in disordered weight control behaviors (RRs ranged from 2.05 to 2.12) and have cosmetic procedures (RRs ranged from 2.91 to 3.89) compared to participants who perceived no sociocultural influence. Men who were influenced by traditional or social media were more likely to engage in disordered weight control behaviors and have cosmetic procedures than similarly influenced women. The high 3-month prevalence of disordered weight control behaviors and lifetime prevalence of cosmetic procedures in Asia is concerning. More research is needed to develop effective preventive interventions in Asia for men and women to promote a healthy body image.

    BACKGROUND: Professional and personal boundaries are blurred with the wide application of social media (SM) in the health professions line of work. Little is known about practice of extending friend requests to patients and faculty members among dental students, which encompass a part of E-professionalism. The aim of this study is to assess the factors associated with the perceptions and practices of interactions with patients and faculty on SM among dental students from Malaysia and Finland.

    METHODS: Dental students from 4 institutions in Malaysia and Finland completed self-administered questionnaires on the practices and perceptions of SM use. The main variables assessed were the perceptions and practices of student-patient and student-faculty communication on SM, between the two countries. Students' country, age, gender, time spent on SM and perceived importance of communicating dental related aspects over SM were analysed as potential explanatory variables. Crosstabulation was used to estimate the distributions of the response variables by the background characteristics. Multivariate analyses were performed using a dichotomous logistic regression model to investigate relevant associations between the responses and the explanatory variables independent from other factors.

    RESULTS: A total of 643 students completed the survey in March-April 2021. More Malaysian students agreed with "guiding patients online is a new responsibility for dentists in the digital age" compared to Finnish students (86.4% vs. 73.4%). Similarly, significantly more Malaysian students befriended patients (14.1% vs. 1%) and invited faculty to be friends on SM (73.6% vs. 11.8%). Expectedly, clinical year students befriended patients more than pre-clinical (13.8% vs. 6.8%). Significantly more students who felt 'communication of dental related issues over SM' were likely to extend friend requests to faculty rather than accept patient friend requests.

    CONCLUSIONS: Social media regulations and socio-cultural practices contribute to dental students' attitudes and behaviour when befriending patients and faculty members on social media. Future dental curriculum should incorporate guidelines for professional communication on social media based on local and cultural needs. Students' should be encouraged to interact with their patients using professional identities on social media.

    African swine fever (ASF) is one of the highly contagious diseases of pigs that affect both domestic and wild pigs. The primary purpose of this research was to evaluate the online social attention on the ASF research to inform the research scientists and key stakeholders in the field by reporting the concise information of the most influential articles, social engagement, and impacts of the research. This study employed the altmetrics tool to evaluate the research papers. Bibliographic data of 100 articles were collected from Scopus; altmetric data was collected from the Altmetric.com database and analyzed using SPSS and Tableau. The articles were mainly mentioned on Twitter, followed by News Outlets and significant readers on Mendeley. Pearson correlation coefficients revealed a weak and insignificant correlation between Scopus Citation and Altmetric Attention Score (AAS). Mendeley Readership and Scopus Citation were moderately correlated. However, there was a significant positive correlation between the AAS and Mendeley readership. Using altmetric tools, the paper is the first research to shed light on the characteristics of ASF on social media.

    Nowadays, social media has become the main source of news around the world. The spread of fake news on social networks has become a serious global issue, damaging many aspects, such as political, economic, and social aspects, and negatively affecting the lives of citizens. Fake news often carries negative sentiments, and the public's response to it carries the emotions of surprise, fear, and disgust. In this article, we extracted features based on sentiment analysis of news articles and emotion analysis of users' comments regarding this news. These features were fed, along with the content feature of the news, to the proposed bidirectional long short-term memory model to detect fake news. We used the standard Fakeddit dataset that contains news titles and comments posted regarding them to train and test the proposed model. The suggested model, using extracted features, provided a high detection accuracy of 96.77% of the Area under the ROC Curve measure, which is higher than what other state-of-the-art studies offer. The results prove that the features extracted based on sentiment analysis of news, which represents the publisher's stance, and emotion analysis of comments, which represent the crowd's stance, contribute to raising the efficiency of the detection model.

    BACKGROUND: Chatbots have become a promising tool to support public health initiatives. Despite their potential, little research has examined how individuals interacted with chatbots during the COVID-19 pandemic. Understanding user-chatbot interactions is crucial for developing services that can respond to people's needs during a global health emergency.

    OBJECTIVE: This study examined the COVID-19 pandemic-related topics online users discussed with a commercially available social chatbot and compared the sentiment expressed by users from 5 culturally different countries.

    METHODS: We analyzed 19,782 conversation utterances related to COVID-19 covering 5 countries (the United States, the United Kingdom, Canada, Malaysia, and the Philippines) between 2020 and 2021, from SimSimi, one of the world's largest open-domain social chatbots. We identified chat topics using natural language processing methods and analyzed their emotional sentiments. Additionally, we compared the topic and sentiment variations in the COVID-19-related chats across countries.

    RESULTS: Our analysis identified 18 emerging topics, which could be categorized into the following 5 overarching themes: "Questions on COVID-19 asked to the chatbot" (30.6%), "Preventive behaviors" (25.3%), "Outbreak of COVID-19" (16.4%), "Physical and psychological impact of COVID-19" (16.0%), and "People and life in the pandemic" (11.7%). Our data indicated that people considered chatbots as a source of information about the pandemic, for example, by asking health-related questions. Users turned to SimSimi for conversation and emotional messages when offline social interactions became limited during the lockdown period. Users were more likely to express negative sentiments when conversing about topics related to masks, lockdowns, case counts, and their worries about the pandemic. In contrast, small talk with the chatbot was largely accompanied by positive sentiment. We also found cultural differences, with negative words being used more often by users in the United States than by those in Asia when talking about COVID-19.

    CONCLUSIONS: Based on the analysis of user-chatbot interactions on a live platform, this work provides insights into people's informational and emotional needs during a global health crisis. Users sought health-related information and shared emotional messages with the chatbot, indicating the potential use of chatbots to provide accurate health information and emotional support. Future research can look into different support strategies that align with the direction of public health policy.

    TikTok use and overuse have grown rapidly in recent years among adolescents. However, risk factors for problematic TikTok use are still largely unknown. In addition, drawing on the flow theory and parental mediation theory, this study aims to examine how adolescents' perceptions of enjoyment, concentration, and time distortion affect their problematic TikTok use behavior. Further, we examined the moderating effect of active parental mediation. An online survey in China received responses from a sample of 633 adolescents between the ages of 10 and 19 (males: 51.2%; Mage = 15.00; DS = 0.975). Our findings showed that enjoyment was positively associated with concentration and, in turn, with time distortion. We also found significant positive effects of concentration and time distortion on problematic TikTok use. The effect of enjoyment, however, was non-significant, indicating that hedonic mood was not associated with problematic TikTok use. Out of the three moderated relationships examined in this study, only active parental control was found to be a significant moderator for the relationship between concentration and problematic TikTok use. The significant negative moderation result showed that as active parental mediation grows, the impact of adolescents' concentration on problematic TikTok use is reduced. Future research directions and implications are discussed.

    The use of social media has increased during the COVID-19 pandemic because people are isolated and working from home. The use of social media enhances information exchange in society and may influence public protective behavior against the COVID-19 pandemic. The purpose of this study is to identify the factors affecting public protective behavior when relying on COVID-19 pandemic-related content shared on social media. A model based on Protection Motivation Theory (PMT) was proposed and validated using a quantitative survey approach. A questionnaire was distributed to random respondents, and 488 responses were received and analyzed using Smart-PLS software. The findings showed that perceived risk, e-health literacy, public awareness, and health experts' participation influence public protective behavior when using social media to share COVID-19-relevant content. The outcomes of this study can enhance government agencies' and public health care authorities' understanding of how to use social media to raise awareness and reduce panic among the public.
