Kamala Harris is the first American Presidential Candidate to understand TikTok. Both her personal feed and campaign feed demonstrate this understanding. This essay will unpack what it means to create TikTok native content, and how Harris is doing so on TikTok.

Within Holocaust studies, there has been an increasingly uncritical acceptance that by engaging with social media, Holocaust memory has shifted from the ‘era of the witness’ to the ‘era of the user’ (Hogervorst 2020). This paper starts by problematising this proposition. This claim to a paradigmatic shift implies that (1) the user somehow replaces the witness as an authority of memory, which neglects the wealth of digital recordings of witnesses now circulating in digital spaces and (2) agency online is solely human-centric, a position that ignores the complex negotiations between corporations, individuals, and computational logics that shape our digital experiences. This article proposes instead that we take a posthumanist approach to understanding Holocaust memory on, and with, social media. Adapting Barad's (2007) work on entanglement to memory studies, we analyse two case studies on TikTok: the #WeRemember campaign and the docuseries How To: Never Forget to demonstrate: (1) the usefulness of reading Holocaust memory on social media through the lens of entanglement which offers a methodology that accounts for the complex network of human and non-human actants involved in the production of this phenomenon which are simultaneously being shaped by it. (2) That professional memory institutions and organisations are increasingly acknowledging the use of social media for the sake of Holocaust memory. Nevertheless, we observe that in practice the significance of technical actancy is still undervalued in this context.

TikTok is a global social media platform popular with young people, encouraging viewers to engage with user-generated video content (through likes, shares and comments) and mimic displayed behaviours (by creating similar videos or content). It is therefore a powerful and engaging tool that has potential for the widespread dissemination of information (or misinformation) and to influence behaviours. Social media is saturated with the promotion of ‘diet culture’ and has a strong influence on the eating behaviours of young people (1,2). This is concerning as childhood and adolescence are critical periods of growth requiring optimal nutrition (3). This study aimed to investigate how dieting is portrayed on TikTok and consider the potential implications for public health. A cross-sectional descriptive content analysis was undertaken of 50 videos from each of the five most popular diet-related hashtags (#diet, #whatieatinaday, #wieiad, #dietitian, #diettips). A codebook was developed to analyse the body-related content referenced (weight measurement, calories, body image, body checking, body comparisons over time) and collect the engagement for each video (likes, comments and shares). Overall, the 250 videos contributed to a total of 197.2 million likes (M = 789,051.0, SD = 923,335.0), 126,7251 comments (M = 5,069.0, SD = 9,315.3), and 3.8 million shares (M = 15,423.2, SD = 41,271.3). Most videos featured adults (n = 205, 82%), and only a small number of videos featured identifiable children or adolescents (n = 16, 6.4%). The information and advice regarding diets and eating behaviours came from two types of sources: 'experts’ and regular creators sharing their personal experience. Almost half of the videos were educational or instructional (n = 116, 46.4%), of which 74 (63.8%) were posted by users who claimed expert status. The most common titles by those claiming to be experts were “dietitian” (n = 43, 58.1%), “health and wellness coach” (n = 7, 9.5%), “doctor” (MD; n = 6, 8.1%), “fitness trainer” (n = 6, 8.1%), and “nutritionist” (n = 3, 4.1%). Of the videos that specifically mentioned a certain diet, the most common diets were low calorie (n = 32, 12.8%), vegan (n = 14, 5.6%), self-reported healthy eating (n = 12, 4.8%), and fasting (n = 10, 4.0%). The use of humour was the only feature significantly associated with engagement. Health professionals are presented with a unique opportunity to widely and positively influence the public by utilising the popularity of TikTok amongst young people to disseminate evidence-based information and promote healthy eating behaviours. Our findings suggest that experts using authentic, humorous, and engaging personas would be more likely to be popular on this platform.

A ‘Blackout Rage Gallon’ (borg) is a dangerous new alcohol consumption trend popular with young people. It involves creating a customised, individual alcoholic beverage by replacing half the water in a four litre (gallon) jug with alcohol (usually spirits), flavourings, electrolytes and caffeinated energy drinks or caffeine supplements. The most prevalent ‘recipe’ calls for the addition of 750ml of alcohol. The ‘blackout’ part of the name refers to the intent of one person to consume the borg in one session, thereby encouraging risky alcohol use. Indeed, there have been reports in popular media of multiple hospitalisations attributed to consumption of borgs at college events in the United States. Part of the attraction of the trend is to label the borg with a clever name, usually incorporating the term ‘borg’. The trend has gained traction recently on TikTok, which has become an important, yet unregulated, source of information for the public including young people(1). We investigated TikTok videos associated with the hashtag #borg to better understand this dangerous new phenomenon. We identified and analysed highly viewed TikTok videos (n = 105) for engagement, techniques, characteristics of featured individuals, and the portrayal of alcohol and risky drinking behaviours. Alcohol was visible in three quarters of the videos analysed (n = 78), and consumed in one third (n = 34). The average amount of alcohol present was well in excess of safe drinking guidelines (865ml) One quarter of videos (n = 25) promoted alleged benefits such as control of volume of consumption, protection from drink spiking, and mitigation of side effects due to addition of electrolytes and water. Alarmingly, only 9 videos included a warning about potential harms of the borg or alcohol in general. Indeed, videos discussing potential harms and benefits tended to encourage the use of borg, for example ‘I’m on board with the borg’. Our study found the borg TikTok trend encourages risky drinking in a fun and entertaining way, supporting previous studies where the majority of content was positively portraying a product or behaviour(2). As there is an association between viewing alcohol-related content on social media and alcohol use(3), there is an urgent need for social media content restrictions to limit the visibility of risky alcohol consumption, particularly to underage users.

With continuing population growth and increased urbanisation, the prevalence of apartment living will also increase. The food practices and diet of apartment residents may differ to those in lower density, detached or semi-detached housing. Food practices may be impacted by physical constraints of apartment kitchens (size, storage, cooking facilities) and the influence of the surrounding community food environment, particularly in smaller apartments. High-rise apartment residents spend a larger proportion of their weekly household budget on eating foods prepared out of the home 1. This is concerning given meals prepared outside the home tend to be of lower diet quality 2 and are associated with higher body weight 3. This study investigated how kitchens, residents’ food practices and hypothesised barriers to healthy eating were portrayed on popular TikTok videos associated with hashtags denoting small apartments. Using the keyword ‘microapartment’, the top four most viewed hashtags relevant to the topic were identified: #studioapartment (190.5 million views), #smallapartment (152.5 million views), #tinyapartment (62 million views), and #microapartment/ #microapartments (4.9 million views combined). The most liked videos (n = 50) from each of these four hashtags and #apartment (as a comparator) were selected for investigation. Using a REDCap survey, two researchers independently coded a random sample of 15 videos, with comparison and discussion to tighten codebook definitions and reduce ambiguity. Subsequently over half of all videos were coded by at least two researchers, achieving acceptable inter-rater reliability (Cohen’s kappa >0.8). Each video was coded for engagement characteristics, user profile, and characteristics of individuals appearing. Further coding included apartment size, kitchen features displayed or mentioned, and food practices (grocery shopping, cooking at home, and eating foods prepared out of the home). Videos were categorised as having positive sentiment if they depicted the apartment in an explicitly positive way, including promoting or encouraging an aspect of apartment living or indicating support for a behaviour. Conversely, videos were coded as being of negative sentiment where they depicted a clear negative position on an aspect of apartment living. Else, the video was coded as neutral sentiment. The majority of videos (87%) portrayed apartment living with a positive or neutral sentiment; with only 2% of videos portraying kitchen size or function negatively. The expected physical constraints of small apartment kitchens were not evident in the videos, nor were interactions with the food environment surrounding the apartment. Indeed, in the small number of videos portraying the food practices of cooking, shopping and eating, the videos highlighted the ability to undertake these practices despite limitations of size and facilities. As the food practices of residents of small apartments are not well researched, it is not known whether their portrayal on TikTok may indeed reflect reality, or may be a glamorisation.

Antihistamines are among the most widely used medications in the world. Ebastine is an antihistaminic which is long-acting, second-generation, and selective H1-receptor inverse agonist. I report a twelve-year-and-six-month-old girl with temporary prolongation of the QTc interval caused by acute ebastine intoxication due to TikTok challenge. Initial electrocardiogram showed sinus arrhythmia (72 beats/min) and prolongation of the QTc interval (QTc 482 milliseconds). Gastric lavage was performed. Intravenous fluid was administered, and activated charcoal (1 g/kg/per dose) was given. Electrocardiogram 9 h after drug ingestion showed sinus rhythm and normal QTc interval (QTc 414milliseconds). During follow-up, no electrocardiogram abnormalities were detected with electrocardiogram monitoring. She was discharged on day 2 without any complications. This case report is the first in the literature to show acute intoxication with ebastine due to challenge video on TikTok, which leads to a temporary prolongation of the QTc interval. Also, with this case report, I assert the fact that it is important to properly supervise the use of social media, such as TikTok and to review the content of TikTok videos.

Firms from transforming economies can leverage the characteristics of their location to develop innovative business models before internationalizing. This note showcases ByteDance's innovative business model for its TikTok app, which became one of the most downloaded apps globally. ByteDance used its large and increasingly demanding home market to experiment with creative combinations of business model elements to develop a unique business proposition that positions the TikTok app as a hybrid of social networking and video-sharing. In addition, TikTok benefitted from China's IT strength supported by national high-tech policy to an AI-based recommendation algorithm as a non-location bound resource. TikTok shows that firms from transforming economies can launch successful global products through business model innovation.
