In particular, visual materials are playing a crucial role in organizational social media communication. They can manifest the social representations (SRs), which are systems of opinions, knowledge, and/or beliefs shared by a group of people. Based on the social representations t…
The effectiveness of intervention measures on Mers-CoV transmission by using the contact networks reconstructed from link prediction data
Introduction: Mitigating the spread of infectious diseases is of paramount concern for societal safety, necessitating the development of effective intervention measures. Epidemic simulation is widely used to evaluate the efficacy of such measures, but realistic simulation environments are crucial for meaningful insights. Despite the common use of contact-tracing data to construct realistic networks, they have inherent limitations. This study expl…
Personality of organizational social media accounts and its relationship with characteristics of their photos
This study applied the theoretical lens of personality, which has been mainly used to examine individuals' behaviors, to investigate the SNS communication of startups. Moreover, it focused on the visual communication of organizational accounts, which has not been actively studied in the literature. This study has implications for expanding the realm of personality research to organizational SNS accounts
Exploring Organizational Self-(re)presentations on Visual Social Media
Presenting oneself visually is an essential part of online behaviors on social networking sites (SNSs), and this is also the case for organizational accounts. Examining organizational self-presentation on their SNS accounts can show the key instruments through which organizations communicate online with the public. Thus, taking startups' Instagram accounts as examples, this study aims to explore what and how organizations present visually on the …

Effects of Integrative Autism Therapy on Multiple Physical, Sensory, Cognitive, and Social Integration Domains in Children and Adolescents with Autism Spectrum Disorder
This study aimed to compare the effects of conventional autism therapy (CAT) and integrative autism therapy (IAT) in children and adolescents with autism spectrum disorder (ASD). A convenience sample of 24 children with ASD was recruited and underwent either CAT or IAT for 60 min/day, twice a week, for 20 sessions over 10 weeks. Outcome measures included the following: (1) physical domain (pediatric balance scale, PBS), (2) sensory domain (short …
Nomask on Instagram
Social media (SM) functions such as hashtags and photo uploading can enrich and expedite user interactions, but can also facilitate the online spread of antisocial norms. Mask aversion is one such antisocial norm shared on SM in the current COVID-19 pandemic circumstances. This study utilized the social representation theory (SRT) to explore how mask aversion is visually represented in the Instagram photos tagged with #NoMask. It examined the ove…
A Framework-Based Approach to Assessing Mental Health Impacts of the Covid-19 Pandemic on Children and Adolescents
The COVID-19 pandemic has yielded extensive impacts globally in the year of 2020. Although the mental health of children and adolescents may be particularly susceptible to stressors stemming from the pandemic and anti-contagion policies, most ongoing efforts are geared toward curbing the viral spread. In the current perspective, we have identified four domains of factors corresponding to an ecological framework that may directly or indirectly inf…
Personality of Public Health Organizations’ Instagram Accounts and According Differences in Photos at Content and Pixel Levels
Organizations maintain social media accounts and upload posts to show their activities and communicate with the public, as individual users do. Thus, organizations' social media accounts can be examined from the same perspective of that of individual users' accounts, with personality being one of the perspectives. In line with previous studies that analyzed the personality of non-human objects such as products, stores, brands, and websites, this …
Effectiveness of Intervention Strategies on Mers-CoV Transmission Dynamics in South Korea, 2015
The MERS-CoV spread in South Korea in 2015 was not only the largest outbreak of MERS-CoV in the region other than the Middle East but also a historic epidemic in South Korea. Thus, investigation of the MERS-CoV transmission dynamics, especially by agent-based modeling, would be meaningful for devising intervention strategies for novel infectious diseases. In this study, an agent-based model on MERS-CoV transmission in South Korea in 2015 was buil…
Projection Bias and Youth’s and Parents’ Perceptions of Their Joint Political Discussions
This study investigated the idea that youth’s perceptions of the frequency of family political discussions and of parental political support mostly derive from their own political interest, a form of projection bias. Tests were performed of whether the same bias applies to parents, and whether youth’s and parents’ perceptions of political discussions and political support overlap to only a limited extent. Multivariate multiple regression analyses…
Classroom Disorder and Internalizing Problems Among Swedish Adolescents
BACKGROUND: Internalizing problems have increased among Swedish adolescents. We examined whether classroom disorder was associated with internalizing problems and whether it explained the trends in internalizing problems. Furthermore, we examined whether school contextual factors were associated with internalizing problems and whether they moderated the association between classroom disorder and internalizing problems. METHODS: We used repeated c…
Antivaccination on Instagram
A dramatic increase has been registered in the number of social media posts in photo form as well as in hashtag activism. Hashtags, which manifest thoughts and feelings clearly and concisely, originated on Twitter, where the length of a post is limited; their use, however, has expanded into other social media services, including Instagram. Hashtags, which make it easy to find and express support for posts of interest, have been widely used for on…
Mental Health Problems Among Adolescents in Sweden from 1995 to 2011
We compared the mental health of native and immigrant adolescents in Sweden from 1995 to 2011 and examined whether the municipality-level proportion of immigrant adolescents moderated the association between individual-level immigrant status and mental health. The sample (14,189 adolescents aged 15-16) was obtained from a repeated cross-sectional study conducted from 1995 to 2011. Adolescent self-report data (gender, immigrant status, economic si…
Mental health problems among economically disadvantaged adolescents in an increasingly unequal society
Increasing inequality in many societies highlights the importance of paying attention to differences in mental health between the economically disadvantaged adolescents and the non-disadvantaged adolescents. Also important is to understand how changing inequality in society over time influences adolescents' mental health at the population- and individual-level. The current study examined to what extent increased societal-level income inequality o…
Agent-Based Modeling for Super-Spreading Events
Super-spreading events have been observed in the transmission dynamics of many infectious diseases. The 2015 MERS-CoV outbreak in the Republic of Korea has also shown super-spreading events with a significantly high level of heterogeneity in generating secondary cases. It becomes critical to understand the mechanism for this high level of heterogeneity to develop effective intervention strategies and preventive plans for future emerging infectiou…
Trends in adolescent mental health during economic upturns and downturns
Background A long-term trend of increasing mental health problems among adolescents in many Western countries indicates a great need to investigate if and how societal changes have contributed to the reported increase. Using seven waves of repeated cross-sectional data collected between 1988 and 2008 in Sweden, the current study examined if economic factors at the societal level (municipality unemployment rate) and at the individual level (worry …
The longitudinal relation between online and offline political participation among youth at two different developmental stages
The role played by the Internet in young people’s political lives has received great research attention. However, two gaps in the literature hinder the drawing of conclusions on how online political participation is related to its offline counterpart. First, although there are multiple hypotheses on the nature of the relationship, they have not been compared in any single study. Second, although the relation may differ according to developmental …
