The social media time line, especially Twitter, is still interesting to follow. Various tweets delivered by the public are very informative and varied. This information should be able to be used further by utilizing the topic of conversation trends at one time. In this paper, the authors cluster the tweet data with the TF-IDF algorithm and the K-Mean method using the python programming language. The results of the tweet data clustering show predictions or possible topics of conversation that are being widely discussed by netizens. Finally, the data can be used to make decisions that utilize community sentiment towards an event through social media like Twitter.

This paper seeks to understand why there has been an increase in photographic images exposing military violence or displaying bodies killed by military forces and how they can freely circulate in the public without being censored or kept hidden. In other words, it aims to analyze this particular issue as a symptom of the emergence of new wars and a new regime of their visual representation. Within this framework, it attempts to relate two kinds of literature that are namely the history of war and war photography with the bridge of theoretical discussions on the real, its photographic representation, power, and violence.  Rather than systematic empirical analysis, the paper is based on a theoretical attempt which is reflected on some socio-political observations in the Middle East where there has been ongoing wars or new wars. The core discussion of the paper is supported by a brief analysis of some illustrative photographic images that are served through the social media under the circumstances of war for instance in Turkey between Turkish military troops and the Kurdish militants. The paper concludes that in line with the process of dissolution/transformation of the old nation-state formations and globalization, the mechanism and mode of power have also transformed to the extent that it resulted in the emergence of new wars. This is one dynamic that we need to recognize in relation to the above-mentioned question, the other is the impact of social media in not only delivering but also receiving war photographies. Today these changes have led the emergence of new machinery of power in which the old modern visual/photographic techniques of representing wars without human beings, torture, and violence through censorship began to be employed alongside medieval power techniques of a visual exhibition of tortures and violence.

Importance: Social media is widely used by various segments of society. Its role as a tool of communication by the Public Health Departments in the U.S. remains unknown. Objective: To determine the impact of the COVID-19 pandemic on social media following of the Public Health Departments of the 50 States of the U.S. Design, Setting, and Participants: Data were collected by visiting the Public Health Department web page for each social media platform. State-level demographics were collected from the U.S. Census Bureau. The Center for Disease Control and Prevention was utilized to collect information regarding the Governance of each State’s Public Health Department. Health rankings were collected from “America’s Health Rankings” 2019 Annual report from the United Health Foundation. The U.S. News and World Report Education Rankings were utilized to provide information regarding the public education of each State. Exposure: Data were pulled on 3 separate dates: first on March 5th (baseline and pre-national emergency declaration (NED) for COVID-19), March 18th (week following NED), and March 25th (2 weeks after NED). In addition, a variable identifying the total change across platforms was also created. All data were collected at the State level. Main Outcome: Overall, the social media following of the state Public Health Departments was very low. There was a significant increase in the public interest in following the Public Health Departments during the early phase of the COVID-19 pandemic. Results: With the declaration of National Emergency, there was a 150% increase in overall public following of the State Public Health Departments in the U.S. The increase was most noted in the Midwest and South regions of the U.S. The overall following in the pandemic “hotspots,” such as New York, California, and Florida, was significantly lower. Interesting correlations were noted between various demographic variables, health, and education ranking of the States and the social media following of their Health Departments. Conclusion and Relevance: Social media following of Public Health Departments across all States of the U.S. was very low. Though, the social media following significantly increased during the early course of the COVID-19 pandemic, but it still remains low. Significant opportunity exists for Public Health Departments to improve social media use to engage the public better.

BACKGROUND Healthcare is changing rapidly, and consumer focus has become a priority for most organizations. In fact, found that 81% have identified “improving consumer experience” as a high priority for their organization. But only 11% of healthcare executives feel that their organization has the capabilities to deliver positive consumer experience. It’s important to understand that social media has the potential to be both enhancing and damaging, during or after a crisis. There will be numerous rumours and misinformation spreading during a crisis, creating panic among the public, with the aim of making the information ‘go viral.’ Population education or empowerment is important to ensure that the general population doesn’t fall victim to such rumours. Healthcare organisations have a duty to prevent damage in this way, by creating awareness. People should be educated to distinguish between trustworthy and misleading information. For example, we published an article on how misleading information on anorexia is promoted on YouTube, stating that “the illiterate in this ICT era will not be those who cannot read and write, but those who cannot distinguish between trustworthy and misleading information available online” (Syed-Abdul et al. 2013).

Dynamic Relationships

The fast-growing social media in Indonesia has opened up opportunities for spreading feminist ideas to a wider and more diverse audience. Various social media accounts especially Instagram that focus on gender advocacy and feminism such as @indonesiafeminis, @lawanpatriarki, and @feminismanis have developed in Indonesia. However, the development of the social media platform also presents groups that oppose feminists. One of the accounts of women’s groups that oppose feminists is @indonesiatanpafeminis.id (@indonesiawithoutfeminist.id). The research objectives are namely to analyze the diversity of issues and reveal the discourse contestation that developed in the @indonesiatanpafeminis.id, and dynamic relationships on the online and offline spaces between groups of feminists and anti-feminists or the other interest. This research employed the digital ethnography method that utilized observation, interview, and literature study as data collection techniques. This study found that the online conversations at @indonesiatanpafeminis.id revealed misconceptions on feminism from a group of women with a religious identity. Furthermore, the conversation also tends to strengthen patriarchal values with religious arguments that are gender-biased. However, the @indonesiatanpafeminis.id serves as a public space for open debates and education on feminist issues. The anti-feminist group behind the @indonesiatanpafeminis.id are women who identify themselves in a certain Muslim circle that has political, cultural, and religious agendas. One of the agendas is to influence the public to reject the Sexual Violence Eradication Bill. This study also noted the Muslim supporters of anti-feminism in Indonesia are less popular compared to progressive religious-based Muslim women organizations such as Aisyiyah (Muhammadiyah), Muslimat NU (Nahdlatul Ulama), and Rahima (Center for Education and Information on Islam and Women’s Rights). The study also evokes discussion on how the feminist and anti-feminist discourses can be utilized to criticize and develop the women’s movement or feminism in a multicultural context.
