X as a Passive Sensor to Identify Opinion Leaders: A Novel Method for Balancing Visibility and Community Engagement.

The identification of opinion leaders is a matter of great significance for companies and authorities, as these individuals are able to shape the opinions and attitudes of entire societies. In this paper, we consider X (formerly Twitter) as a passive sensor to identify opinion leaders. Given the unreliability of the traditional follower count metric due to the presence of fake accounts and farm bots, our approach combines the measures of visibility and community engagement to identify these influential individuals. Through an experimental evaluation involving approximately 4 million tweets, we showed two important findings: (i) relying solely on follower count or post frequency is inadequate for accurately identifying opinion leaders, (ii) opinion leaders are able to build community and gain visibility around specific themes. The results showed the benefits of using X as a passive sensor to identify opinion leaders, as the proposed method offers substantial advantages for those who are involved in social media communication strategies, including political campaigns, brand monitoring, and policymaking.

TikToks Lead to Higher Knowledge and Perceived Severity of Sexual Violence among Adolescent Men.

Social media communication is a promising way to deliver important health messages about sexual violence to a key population of adolescent men. The researchers conducted an online, between-participants experiment to examine the impact of personal narrative TikToks about sexual violence on adolescent men. Participants were adolescent men (n = 580) aged 15 to 19 (M = 17.3, SD = 1.43). Participants were randomly assigned to treatment (personal narrative TikToks about sexual violence) or control (hair braiding TikTok tutorials) conditions. Adolescent men who viewed personal narrative TikToks about sexual violence had higher knowledge of consequences and higher perceived severity of sexual violence. Additionally, adolescent men found personal narrative TikToks more attention-grabbing (vs. control) and did not have negative reactions. Findings that short (approximately one-minute) TikTok videos led to differences in knowledge and beliefs among, and were interesting and not aversive to, adolescent men are important for sexual violence prevention research. Health messages on TikTok can help shift adolescent perceptions of sexual violence, which is a key starting point towards changing norms.

Sustainable development of multi-media communication path of broadcasting and hosting with a dynamic environment.

To enrich people's lifestyles at home, the research on the transmission path of new media broadcasting and hosting programs has become a hot topic. The traditional statistical regression model has low prediction accuracy and weak generalization ability on such issues. Therefore, we propose an improved comprehensive path planning algorithm based on an ant colony algorithm to search for the optimal path of the multi-media transmission for broadcasting and hosting programs in a dynamic environment. Firstly, we improve the bidirectional search strategy, optimize the probability transition and extend the early search scope. Then, we utilize the allocation strategy of the wolf to change the updating rules of the pheromone. Finally, we take the shortest process time for listeners to obtain the broadcast program as the optimization goal and construct a comprehensive evaluation model. We also solve the optimal parameters to improve the overall performance of our method for finding out the excellent path of multi-media transmission in a dynamic environment. Experiment results show that our method can achieve the optimal route plans and we can demonstrate that the path planned by the improved ant colony algorithm is more reasonable, which can effectively avoid the optimum local problem and shorten the solution.

Application of public emotion feature extraction algorithm based on social media communication in public opinion analysis of natural disasters.

Natural disasters are usually sudden and unpredictable, so it is too difficult to infer them. Reducing the impact of sudden natural disasters on the economy and society is a very effective method to control public opinion about disasters and reconstruct them after disasters through social media. Thus, we propose a public sentiment feature extraction method by social media transmission to realize the intelligent analysis of natural disaster public opinion. Firstly, we offer a public opinion analysis method based on emotional features, which uses feature extraction and Transformer technology to perceive the sentiment in public opinion samples. Then, the extracted features are used to identify the public emotions intelligently, and the collection of public emotions in natural disasters is realized. Finally, through the collected emotional information, the public's demands and needs in natural disasters are obtained, and the natural disaster public opinion analysis system based on social media communication is realized. Experiments demonstrate that our algorithm can identify the category of public opinion on natural disasters with an accuracy of 90.54%. In addition, our natural disaster public opinion analysis system can deconstruct the current situation of natural disasters from point to point and grasp the disaster situation in real-time.

Telehealth uptake among middle-aged and older Americans during COVID-19: chronic conditions, social media communication, and race/ethnicity.

OBJECTIVES: This study investigated whether and to what extent constructs of the protection motivation theory of health (PMT)-threat appraisal (perceived vulnerability/severity) and coping appraisal (response efficacy and self-efficacy)-are related to telehealth engagement during the COVID-19 pandemic, and how these associations differ by race/ethnicity among middle-aged and older Americans. METHODS: Data were from the 2020 Health and Retirement Study. Multivariable ordinary least-squares regression analyses were computed adjusting for health and sociodemographic factors. RESULTS: Some PMT constructs are useful in understanding telehealth uptake. Perceived vulnerability/severity, particularly comorbidity (b = 0.13, 95% confidence interval (CI) [0.11, 0.15], p < 0.001), and response efficacy, particularly participation in communication via social media (b = 0.24, 95% CI [0.21, 0.27], p < 0.001), were significantly and positively associated with higher telehealth uptake during the COVID-19 pandemic among middle-aged and older Americans. Non-Hispanic Black adults were more likely to engage in telehealth during the pandemic than their non-Hispanic White counterparts (b = 0.20, 95% CI [0.12, 0.28], p < 0.001). Multiple moderation analyses revealed the significant association between comorbidity and telehealth uptake was similar across racial/ethnic groups, whereas the significant association between social media communication and telehealth uptake varied by race/ethnicity. Specifically, the association was significantly less pronounced for Hispanic adults (b = -0.11, 95% CI [-0.19, -0.04], p < 0.01) and non-Hispanic Asian/other races adults (b = -0.13, 95% CI [-0.26, -0.01], p < 0.05) than it was for their non-Hispanic White counterparts. CONCLUSION: Results suggest the potential of using social media and telehealth to narrow health disparities, particularly serving as a bridge for members of underserved communities to telehealth uptake.

Social Media's Use and Impact on Oral Surgeons and Oral Surgery Residents.

INTRODUCTION: Social networks are now an effective tool in medical communication used in many specialties. It provides wide access to patients and pears communities because the engagement of all age ranges on Facebook and Instagram is growing. More and more training programs are using these platforms to promote themselves to future students, including those in oral and maxilla-facial surgery. But the impact of specialized medical content has never been studied on the population of working practitioners and residents. METHOD: In this study, an anonymous online survey was distributed by email to French oral surgeons and French oral surgery residents. The questionnaire was accessible for a period of two months and included questions about demographic data and the professional use of different social networks. RESULTS: It received a total of 206 participations. All ages and professional statuses were represented. Around two-thirds of respondents were 25 to 35 years old. A large majority of the respondents (86%) had an account on at least one social media site, and 74% of those aged 25 to 35 were present on Facebook and Instagram at least. Residents at 65% affirmed they use social media as a source of medical information, in contrast to academic professors at 30%. This online content had a higher impact on residents' medical experiences compared with other groups. Twenty-nine surgeons declared to post occasionally or regularly on social media; most of them were private practitioners. The role of social media in oral and maxilla-facial surgery practice was judged significant or inevitable by 44.3% of the respondents. CONCLUSION: This preliminary survey of a small sample shows the growing interest of interns and young practitioners in medical content published by the professional community on social media as a source of non-institutional information.

Analysis of consumer product preference and news media based on data mining technology.

Media representations of crimes in close relationships: Qualitative analysis of narratives in a television broadcast.

Recent years have seen increased media attention paid to crimes committed against women by partners or former partners has grown. Crime, especially violent crime, dominates the news and the mass media. In this sense, criminology" impacts publicly the collective representation of crime. The study was motivated by the interest to understand what representations are conveyed by television broadcasts and how closely related they are to criminological theories and literature on the subject. The objective of the proposed qualitative research is to examine the media representations proposed in thematic television broadcasts, as well as the narrative profiles relating to the victims, perpetrators of the crimes and their relationships, as described in the news and by a multiplicity of roles associated with them based on kinship, friendship or professional role.

Eight Patients With Pilonidal Carcinoma in One Decade-Is the Incidence Rising?

INTRODUCTION: Carcinoma secondary to pilonidal disease is very rare with fewer than 130 reported cases so far. It is presumed that underreporting and underpublishing contribute to the low reported incidence. METHODS: A post was published on a closed Facebook group with about 30,000 Syrian doctors asking if anyone had ever seen a patient with pilonidal carcinoma before. The patients' data were collected retrospectively from the treating physicians. RESULTS: Between 2010 and 2019, we identified eight patients with pilonidal carcinoma. All patients were males with a mean age of 55.5 years. The mean interval between diagnosis of pilonidal disease and diagnosis of carcinoma was 6.9 years. A growing ulcer on the background of a pilonidal sinus disease was the presenting complaint in 50% of cases. Three patients were lost from follow-up after the diagnosis due to referral. All other five patients underwent surgical resection and three of them received postoperative chemoradiation. Four patients were followed for six months or longer: two died of metastases, one survived after recurrence and re-excision, and one survived with no recurrence. CONCLUSION: This paper presents the largest cohort of pilonidal carcinoma so far and the first that describes the disease in the Syrian population. Due to underreporting, the real incidence of pilonidal carcinoma exceeds what is reported so far in the literature.

"Say a Little but Say It Well": Assessing the Impact of Social Media Communication on Value Co-creation, Online Customer Experience, and Customer Well-Being.

The purpose of the study is to identify how both tourism service provider- and tourist-generated social media communication affect the value co-creation process and how this can affect online customer experience and customer wellbeing. A questionnaire survey was used and 361 valid responses were obtained from Malaysian citizens. The research findings showed that tourism service provider- and tourist- generated social media communication positively influence value co-creation. Similarly, value co-creation positively influences cognitive and affective experiential states and these two states positively influence customer wellbeing. Furthermore, value co-creation partially mediates the relationship between social media communication and online customer experience, whereas, online customer experiences also partially mediate the relationship between value co-creation and customer wellbeing. This study has tried to establish theoretical relationship between some significant variables and the findings would aid both academicians and practitioners in formulating strategies for future.

Evaluating South African and Namibian governments' use of digital media during Covid-19.

Governments during the Covid-19 pandemic in response to the challenge of reaching as many of their citizens as quickly as possible have relied on the use of digital media communication. Various stakeholders, however, have questioned whether strategic use of digital communication by governments has been effective during the Covid-19 health crisis. We thematically analyzed a public online bi-country webinar and conducted a netnographic analysis of South African Health Minister Dr. Zweli Mkhize and Namibian Ministry of Health and Social Services Twitter accounts to evaluate the effectiveness of government digital communication during the Covid-19 pandemic. Stakeholders and social media analysis highlight that government digital communication has lacked engagement, falling short in assisting citizens to understand the effects of the Covid-19 pandemic. We highlight the shortcomings of governments simply transmitting information on channels built for dialogue, the digital divide limiting reach, as well as how limited engagement opens up opportunities for misinformation.

Neoliberalismo e a construção do sujeito criativo / Neoliberalismo y construcción del sujeto creativo / Neoliberalism and the construction of the creative subject

Resumo: O presente artigo visa a problematizar o lugar da categoria "sujeito criativo" na contemporaneidade, assim como suas vinculações com os padrões estabelecidos pelas práticas de mercado. Foram analisados dois discursos midiáticos proferidos no programa Saia Justa (GNT) e em um comercial do programa Shark Tank (ABC), ambos voltados à criatividade e ao empreendedorismo no contexto da pandemia de covid-19. A metodologia de análise teve como base a Análise de Discurso de linha francesa. Os resultados evidenciam um sujeito criativo construído a partir de um mecanismo neoliberal que (a) silencia discursivamente a contradição desigualdade-universalidade; (b) atribui valor à criatividade (e ao sujeito criativo) a partir da lógica de mercado (consumo e concorrência); e (c) induz, pelo processo de interpelação, o sujeito a identificar-se com este Outro neoliberal e regular suas volições criativas a partir desse.

Resumen: Este artículo busca problematizar el lugar de la categoría "sujeto creativo" en la época contemporánea, así como sus vínculos con los padrones establecidos por las prácticas de mercado. Se analizaron dos discursos mediáticos pronunciados en el programa Saia Justa (GNT) y en un comercial del programa Shark Tank (ABC), ambos enfocados en la creatividad y el espíritu empresarial en el contexto de la pandemia covid-19. La metodología de análisis se basó en el Análisis del Discurso de matriz francesa. Los resultados muestran un sujeto creativo construido a partir de un mecanismo neoliberal que (a) silencia discursivamente la contradicción desigualdad-universalidad; (b) asigna valor a la creatividad (y al sujeto creativo) desde la lógica del mercado (consumo y competencia); y (c) induce, a través del proceso de interpelación, al sujeto a identificarse con este Otro neoliberal y regular sus voliciones creativas a partir de él.

Abstract: This article aims to problematize the position of the "creative subject" category in contemporary times, as well as its relations with the standards established by market practices. Two media discourses were analyzed, one uttered in the Saia Justa (GNT) TV show and the other in a commercial from the Shark Tank (ABC) TV show, both of them focused on creativity and entrepreneurship in the context of the COVID-19 pandemic. The analysis methodology was based on the French approach of Discourse Analysis. The results show a creative subject built from a neoliberal mechanism that (a) discursively silences the inequality-universality contradiction; (b) assigns value to creativity (and to the creative subject) based on the market logic (expenditure and competition); and (c) through the process of interpellation, induces the subject to identify him/herself with this neoliberal Other and regulate his/her creative volitions based on it.

The practice of and reflection on hospital publicity in post-epidemic era / 西安交通大学学报(医学版)

In the wake of the COVID-19 pandemic, only through whole-hearted cooperation and joined efforts can medical institutions, governments, and social organizations cope with emergency, convert the crisis into opportunities, promote modern governance and accomplish high-quality development in the fight against the pandemic. Taking the First Affiliated Hospital of Xi’an Jiaotong University as an example, this paper analyzes the all-media communication matrix of "one network platform, 3W + N" that the hospital established during the pandemic by combining the authoritative official website with WeChat, Wesee, Weibo and that other publicity media. The study explores how to create a publicity brand that is mindful, poignant, compassionate and devoted and maintains its scientific and refined management, so as to achieve the professional goal of educating the public, shouldering the responsibility in the combat against the pandemic, and taking the lead in the research on the pandemic.

Social Media in Physician Education.

Background Social media has fundamentally changed the practice of medicine. It has taken the medical community by storm, benefited patient care, and has become a leading source for distributing medical information. Social media platforms are a low-cost, low-barrier entry means for health systems to highlight their competitive advantage to patients and providers alike. This study aimed to assess the role of social media in the education of physicians. Methods To evaluate the utility of social media in engaging physicians, four vignettes were utilized to highlight Class 1 indications for transvenous lead extraction (TLE), an electrophysiology procedure aimed at removing infected or damaged cardiac device leads. Individuals, via Twitter, were presented with cases and multiple-choice response options to determine the next best step in management. Results The clinical vignettes were seen by more than 18,000 individuals worldwide. Survey results indicated that 83% of individuals who participated had correctly identified class 1 indications for this life-saving procedure. Sixteen percent to 21% of physicians incorrectly identified the next step in the management of Class 1 indications for lead extraction, representing a need for education and an opportunity to inform and educate. Conclusion Social media may be a useful tool in physician education. However, guidelines and further research are needed to continue to understand the role of social media within the medical field.

Psychological Aspects of Media Communication during the COVID-19 Pandemic: Insights from Healthcare and Pharmacy Specialists in Lithuania.

In the setting of disasters, people seek information as they hope that knowledge will provide security. This makes the media a critical source of crisis exposure. The aim of the study described in this article was to analyze COVID-19 pandemic-related psychological aspects of media use by healthcare and pharmacy workers in Lithuania and to reveal the subjective effects of media consumption on their psychological well-being. 967 healthcare workers and pharmacists in Lithuania completed an electronic survey, which consisted of questions about the changes in well-being experienced since the beginning of the lockdown and media use in the search for information on COVID-19. It was found that communication might have ambiguous effects on psychological well-being. Excessive, unreliable, misleading, contradictory information and "catastrophizing" were subjectively related to impaired psychological well-being. Objective and reliable, relevant, clear, timely, hopeful and supportive information had a subjective positive effect. Seeking COVID-19-related information many times a day was associated with increased fear of becoming infected with COVID-19, feeling unable to control the risk of contracting COVID-19, fear of infecting relatives with COVID-19 and feeling that other people would avoid interaction with healthcare workers and pharmacists because of their job. General browsing was not consistently associated with COVID-19-related fears.

The Effects of COVID-19 Risk Perception on Travel Intention: Evidence From Chinese Travelers.

This study attempts to assess the relationship between risk perception, risk knowledge, and travel intentions of Chinese leisure travelers during the COVID-19 pandemic in the framework of social contagion and risk communication theories by analyzing a sample of 1,209 travelers through structural equation modeling (SEM) and path analysis. We used the process macro of Hayes to analyze the moderation effects of age, gender, and education between risk perception, media and interpersonal communication, and risk knowledge. It was found that travelers were more concerned about self-efficacy than severity. Risk perception of travelers predicts the information-seeking process of tourists. This process helps travelers to accumulate risk information that influences their travel intentions. Travelers give more importance to interpersonal (contagion) communication in making a traveling decision. Demographic factors influence traveling decision-making; women travelers were found to be more risk resilient than men. Young travelers seek information at low- and old travelers at high-risk levels. Marketing implications also provided.

Health authorities' health risk communication with the public during pandemics: a rapid scoping review.

BACKGROUND: Responses from the H1N1 swine flu pandemic and the recent COVID-19 coronavirus pandemic provide an opportunity for insight into the role of health authorities' ways of communicating health risk information to the public. We aimed to synthesise the existing evidence regarding different modes of communication used by health authorities in health risk communication with the public during a pandemic. METHODS: We conducted a rapid scoping review. MEDLINE and EMBASE were searched for publications in English from January 2009 through October 2020, covering both the full H1N1 pandemic and the response phase during the COVID-19 pandemic. The search resulted in 1440 records, of which 48 studies met our eligibility criteria. RESULTS: The present review identified studies across a broad interdisciplinary field of health risk communication. The majority focused on the H1N1 pandemic and the COVID-19 pandemic. A content analysis of the studies identified three categories for modes of communication: i) communication channels, ii) source credibility and iii) how the message is communicated. The identified studies on social media focused mainly on content and engagement, while studies on the effect of the use of social media and self-protective behaviour were lacking. Studies on the modes of communication that take the diversity of receivers in the field into account are lacking. A limited number of studies of health authorities' use of graphic and audio-visual means were identified, yet these did not consider/evaluate creative communication choices. CONCLUSION: Experimental studies that investigate the effect of health authorities' videos and messages on social media platforms and self-protective behaviour are needed. More studies are needed across the fields of health risk communication and media studies, including visual communication, web design, video and digital marketing, at a time when online digital communication is central to reaching the public.
