The more engaging, the more enjoyable? Age matters in predicting perceived enjoyment with different Facebook activities.

Drawing upon uses and gratifications perspectives and socioemotional selectivity theory, this study examined the differences in the use of Facebook features among younger, middle-aged, and older adults. Furthermore, it explored the association between Facebook activities and users' perceived enjoyment for different age groups. An online survey was conducted with 647 Facebook users in the United States.

A Unified Neural Network Framework for Extended Redundancy Analysis.

Component-based approaches have been regarded as a tool for dimension reduction to predict outcomes from observed variables in regression applications. Extended redundancy analysis (ERA) is one such component-based approach which reduces predictors to components explaining maximum variance in the outcome variables. In many instances, ERA can be extended to capture nonlinearity and interactions between observed and components, but only by specifying a priori functional form.

Thinking about Social Consequences of COVID-19 Influenced Preventive Intention: The Case of South Korea.

Although South Korea has been relatively successful in addressing the COVID-19 pandemic, there were controversies surrounding the negative social consequences (SC) associated with the infection, such as breach of privacy in contact tracing and stigmatization of patients. We examined how individuals' thinking about the SC of COVID-19 infection influenced preventive intention through this specific case, the early phase of the pandemic in South Korea (March, 2020) when concerns regarding SC were very high but vaccines were not available. We theoretically investigated the path from information exposure about COVID-19, worry and risk perception about SC of COVID-19, attitudes/norms/self-efficacy, and preventive intention.

How does WeChat's active engagement with health information contribute to psychological well-being through social capital?

This study aims to examine how the users' engagement with health information benefits their well-being and to demonstrate the underlying mechanism of the relationships through bonding and bridging social capital. An online survey was conducted with 522 WeChat users in China. Structural equation modeling using the maximum likelihood of estimation was employed to test the study's hypothesized model.

Older Adults' Activities on Facebook: Can Affordances Predict Intrinsic Motivation and Well-Being?

This study investigated how older adults' use of specific features on Facebook is associated with intrinsic motivation and well-being. A content analysis and an online survey were conducted with Facebook users older than 60 years ( = 202). Results showed that profile customization and commenting are positively associated with feelings of autonomy and relatedness, respectively, both predictors of enjoyment on Facebook.

SNS Usage and Third-person Effects in the Risk Perception of Zika Virus among Singaporean Women.

This study examines the SNS activities of Singaporean women to assess how they perceive the risk of Zika virus infection based on the consumption of Zika-related news. Results from an online survey ( = 510) confirmed that third-person risk perception exists among study participants. Individual posting of ZIKA-related news on SNSs was negatively associated with third-person perception.

Modeling the Pathway Linking Health Information Seeking to Psychological Well-Being on WeChat.

Guided by the three-stage model and the integration of key constructs from the Health Belief Model, this study proposed a conceptual model to delve into the underlying mechanism linking health information seeking to psychological well-being. A nationwide online survey was administered, involving 522 WeChat users in China. The results of structural equation modeling analysis showed that health consciousness and WeChat health information reliability are significant antecedents predicting users' health information-seeking actions on WeChat, while perceived susceptibility, severity, and self-efficacy did not have significant relationships with such behavior.

WeChatting for Health: An Examination of the Relationship between Motivations and Active Engagement.

As one of the largest mobile social media in the world, WeChat holds great potential for promoting health. Users not only seek and exchange health information on WeChat but also fulfill their health-related needs afforded by the platform. Using the two-step procedure common in uses and gratifications research, in-depth interviews were conducted with 18 WeChat users to explore their motivations for health-related uses on the platform, which were further rated by 522 WeChat users in China through a national wide online survey.

Targeting ROR1 inhibits the self-renewal and invasive ability of glioblastoma stem cells.

Glioblastoma is the most malignant of brain tumours and is difficult to cure because of interruption of drug delivery by the blood-brain barrier system, its high metastatic capacity and the existence of cancer stem cells (CSCs). Although CSCs are present as a small population in malignant tumours, CSCs have been studied as they are responsible for causing recurrence, metastasis and resistance to chemotherapy and radiotherapy for cancer. CSCs have self-renewal characteristics like normal stem cells.

Theories and Messages in South Korean Antismoking Advertising.

This study evaluated antismoking advertisements in South Korean television by drawing upon a Health Communication article by Cohen, Shumate, and Gold (2007) and on Gold, Cohen, and Shumate's (2008) typology. This study examined the theories and messages in South Korean antismoking advertisements. First, South Korean antismoking advertisements primarily targeted adults.
