The erosion of the gatekeeping function of photojournalists in the digital age
In today’s digital news media environment, where the number of professional staff photojournalists is declining, this study examines the extent to which images outsourced from external sources, including vested groups, are published, and how the visual quality of images varies by photo source: 1) staff photojournalist, 2) wire services, 3) social media, 4) news sources, and 5) citizens. Computational and statistical analyses of 7,651 online news …
How does violence in a webcomic relate to user ratings of the webcomic and perceptions of violence in the webcomic
We examined how the amount of violence depicted in a webcomic episode was related to readers’ ratings of the episode and their perceptions of violence. Furthermore, we investigated how the relationships varied depending on whether the webcomic was action-oriented. To measure violence and readers’ perceptions, we used computational methods based on deep learning, and the relationships between the variables were analyzed using regression models. We…
Analyzing Shared Value Creation in Korea’s Public Buildings
The recent expansion of function-driven public buildings constructed for the public interest has escalated conflicts over social issues, such as housing and the environment. Despite efforts, government-led public architecture projects often leave room for improvement in addressing social and environmental challenges. This study identifies shared value creation (CSV) factors in public buildings by employing Latent Dirichlet Allocation (LDA) for to…
Bert and Bertopic for screening clinical depression on open-ended text messages collected through a mobile application from older adults
These results imply that collecting respondents' reports regarding stressful experiences can be useful to screen the risk of clinical depression. Including this function within a smartphone application publicly administered by community health care professionals can help monitor mental health in older adults. It can approach a hidden high-risk population suffering from depression in the community, providing enriched information about their risk f…
Socio-economic and Policy Determinants of Low Fertility in OECD Countries (2014–2023)
Low fertility rates pose significant demographic and economic challenges across many OECD countries, including South Korea. This study examines how economic, social, and policy-related factors collectively influence fertility decisions by employing fixed-effects regression models on panel data from 2014 to 2023. The findings confirm that higher unemployment rates and economic uncertainty negatively affect fertility, whereas family benefit expendi…
Examining the Relationship Between the Violence in a Webcomic Episode and Violence in readers’ Comments with Computational Approaches
We examined how violent scenes and words used in action- and non-action-oriented webcomics were associated with the frequency by which violent words were used in readers’ online comments. Data on the webcomics provided by Naver, a popular webcomics provider, were analyzed with computational approaches. Primary results were as follows: there was a positive relationship between the number of violent words used in a webcomic and that of violent comm…
Exploring the relationship between YouTube video characteristics and a viewer’s mental health traits among young adults
We investigated the relationship between individuals' mental health traits and the characteristics of YouTube videos they watch. The mental health traits considered were stress, depression, anxiety, and self-esteem, which were measured using a survey questionnaire. We considered violence shown in a video, brightness and saturation of a video as video characteristics. We utilized the viewing history log data of the participants and analyzed the vi…
Perceiving as biased but nevertheless persuaded? Effects of fact–checking news delivered by partisan media
The effectiveness of and its boundary conditions regarding fact–checking news exposure have significant normative and practical implications. While many of the prior studies have focused on the attitudinal consequences of fact–checking news delivered by neutral third parties such as fact–check organizations, relatively less is known as to the effect of fact–checking news delivered by partisan media. Based on the frameworks of motivated reasoning …
Media Coverage of Senior and Celebrity Suicides and Its Effects on Copycat Suicides among Seniors
This study examined whether suicide rates in the elderly population are associated with media coverage of senior or celebrity suicides. Analyzing data from 2012 to 2015, we found that seniors were likely to be more influenced by media coverage of senior suicides than by celebrity suicides. Furthermore, the effects of media coverage of senior suicides were more significant when the reported reason was either health (mental or physical problems) or…
Do media coverage of suicides and search frequency on suicides predict the number of tweets seeking others for a suicide pact
We examined whether media coverage of suicides and frequencies of searching for suicide methods or suicide pacts predicted the number of users posting tweets seeking others for a suicide pact. Analyses of 6,119 tweets containing "suicide pact" posted on Twitter during a 6-month period revealed that the number of users posting tweets seeking others for a suicide pact had a positive association with media coverage of celebrity suicides, but not wit…
Engagement in Emotional News on Social Media
This study sheds new light on the relationship between emotion and engagement. Specifically, we investigate how the six discrete emotions that news visuals deliver, as well as the positiveness of news text, are associated with three engagement activities: sharing, commenting, and reacting. The findings show that users are less likely to share or comment on news posts that convey positive emotions, although they tend to react to such news frequent…
Do effects of copycat suicides vary with the reasons for celebrity suicides reported by the media
We examined whether the number of suicides in the public in the weeks following the media coverage of celebrity suicide varied with the reason of the suicide. Using 9-year data, from 2007 to 2015, collected in South Korea, we found that when the reported reason of a celebrity's suicide was either "depression," "financial problems," or "life despair," there were more suicides in the public and more individuals searched for suicide methods on the W…
