Processing Steps

The integrity of images is an important and interesting field of research, since digital images are constantly encountered in everyday life today. The availability of image processing programs makes it possible for almost anyone to manipulate images without great effort. With the help of social media platforms, the hurdle for their distribution to a very large number of viewers has also been lowered. As a result, confidence in the integrity and authenticity of images, which was even stronger at the time of analogue photography, is dwindling. The aim of this work is to develop and investigate a concept that counteracts the lost trust and creates an opportunity to check the integrity of processed images. The concept is based on a combination of signed thumbnails and the logging of possible processing steps. We show that this combination has advantages compared to the existing approaches.

Instagram — one of the biggest social media platforms of our times, brings together many different kinds of users. Content creators and companies try to engage their followers by building relationships with them. Both groups are connected by their willingness to have a positive experience with the plat-form. It uses many functions which greatly facilitate using it. However, why do we even need Instagram in our everyday life?

The use of social media in intensive care has increased steadily since their development in the early 2000s. Usage of social media platforms are now part of everyday life for a sizable proportion of the world’s population. The success of social media relies upon developing a culture where openness and sharing are the norm. This is at odds with traditional medical ethical values such as confidentiality and privacy. Social media can be used for both social and professional purposes, which can lead to unhelpful blurring of lines between personal and professional roles. This chapter discusses guidelines for use of social media for communication purposes by healthcare professionals in the United Kingdom, the benefits and pitfalls of the use of social media for medical education, and the legal aspects of use of social media with respect to intensive care.

This paper analyzes what makes young adults feel insecure when they use social media in everyday life as a means to socialize and connect with peers. The analysis is based on a two-year online ethnography (Hine, 2015) conducted on Jodel, an anonymous location based social media app popular among young adults across Europe. The paper focuses on Jodel users’ anonymous disclosures about their social media related insecurities – shedding light on discourses related to social media practices that are often hidden or neglected in interview studies. The analysis finds that it is often the affordances of the social media platforms (Bucher & Helmond, 2018) or changes in the design of apps such as Snapchat, Instagram or Tinder that lead to feelings of insecurity or uncertainty in relational maintenance or in the forming of new relationships. Thus, the codes of everyday actions become unclear and different expectations as to the affordances of social media platforms result in diffuse interaction orders (Goffman, 1983) in various situations. Put in other words: Because of the platforms, young adults sometimes find it difficult to know why peers behave like they do online resulting in unfounded worries and feelings of insecurity.

The Impact

Background During the COVID-19 pandemic, numerous countries, including China and France, have implemented lockdown measures that have been effective in controlling the epidemic. However, little is known about the impact of these measures on the population as expressed on social media from different cultural contexts. Objective This study aims to assess and compare the evolution of the topics discussed on Chinese and French social media during the COVID-19 lockdown. Methods We extracted posts containing COVID-19–related or lockdown-related keywords in the most commonly used microblogging social media platforms (ie, Weibo in China and Twitter in France) from 1 week before lockdown to the lifting of the lockdown. A topic model was applied independently for three periods (prelockdown, early lockdown, and mid to late lockdown) to assess the evolution of the topics discussed on Chinese and French social media. Results A total of 6395; 23,422; and 141,643 Chinese Weibo messages, and 34,327; 119,919; and 282,965 French tweets were extracted in the prelockdown, early lockdown, and mid to late lockdown periods, respectively, in China and France. Four categories of topics were discussed in a continuously evolving way in all three periods: epidemic news and everyday life, scientific information, public measures, and solidarity and encouragement. The most represented category over all periods in both countries was epidemic news and everyday life. Scientific information was far more discussed on Weibo than in French tweets. Misinformation circulated through social media in both countries; however, it was more concerned with the virus and epidemic in China, whereas it was more concerned with the lockdown measures in France. Regarding public measures, more criticisms were identified in French tweets than on Weibo. Advantages and data privacy concerns regarding tracing apps were also addressed in French tweets. All these differences were explained by the different uses of social media, the different timelines of the epidemic, and the different cultural contexts in these two countries. Conclusions This study is the first to compare the social media content in eastern and western countries during the unprecedented COVID-19 lockdown. Using general COVID-19–related social media data, our results describe common and different public reactions, behaviors, and concerns in China and France, even covering the topics identified in prior studies focusing on specific interests. We believe our study can help characterize country-specific public needs and appropriately address them during an outbreak.

BACKGROUND During the coronavirus disease 2019 (COVID-19) pandemic, numerous countries, including China and France, have implemented lockdown measures that have been shown to be effective in controlling the epidemic. However, little is known about the impact of these measures on the population as expressed on social media from different cultural contexts. OBJECTIVE To assess and compare the evolution of the topics discussed on Chinese and French social media during the COVID-19 lockdown. METHODS We extracted posts containing “COVID-19”- or “lockdown”-related keywords in the most commonly used micro-blogging social media platforms, i.e., Weibo (China) and Twitter (France), from one week before to the lifting of the lockdown. A topic model was applied independently for three periods: pre-lockdown, early lockdown and mid-to-late lockdown, to assess the evolution of the topics discussed on Chinese and French social media. RESULTS 6 395, 23 422 and 141 643 Chinese Weibo messages, and 34 327, 119 919, and 282 965 French tweets were extracted in the pre-lockdown, early lockdown and mid-to-late lockdown periods in China and France, respectively.

This article examines the relationships between cultural spaces, the image-making practices of smartphone users and social media platforms. I argue that social media platforms depend on the curatorial capacities of smartphone users who observe everyday life and register it online. Social media platforms use databases and analytics to continuously assemble identities, cultural practices and social spaces in relation to one another. In addition to targeted advertising, value is created by leveraging a continuous circulation of meaning and attention. Using the example of a music festival, I examine how the production of value involves channelling the productive activity of smartphone users in material cultural spaces.

In recent years, social media has become an integral part of internet users' everyday life. Customers are increasingly seen to be more like “content creators” or even company employees rather than mere customers as they were in the past. In this chapter, we try to understand how customers use the various social media platforms to interact and how this interaction influences the company's marketing policy. An overview of the customers' different uses and practices enabled authors to identify several forms of interactions and to detect their effects on pricing, product, place and promotion, the four main components of the marketing mix.
