TL;DR: Longer daily exposure to TV during early childhood (age 4–5) may be associated with subsequent problematic child self-regulatory behavior, and video games may have a protective effect on the risk of problematic self-Regulatory behavior at ages 3 and 5.
Abstract: Objective The effect of media use on child behavior has long been a concern. Although studies have shown robust cross-sectional relations between TV viewing and child behavior, longitudinal studies remain scarce. Methods We analyzed the Longitudinal Survey of Babies, conducted by Japan's Ministry of Health, Labour and Welfare since 2001. Among 53,575 families, 47,010 responded to the baseline survey; they were followed up every year for 8 years. Complete data were available for longitudinal analysis among 32,439 participants. Daily media use (TV viewing and video game-playing hours at ages 3, 4, and 5 years) was used as the main exposure. We employed an index of the children's self-regulatory behavior as the outcome variable. Odds ratios and 95 % confidence intervals (CIs) were estimated. Results Among boys, longer TV-viewing times at ages 4 and 5 were related to problematic self-regulatory behavior. Compared with boys who watched just 1-2 h of TV a day, those who watched it 4-5 h had a 1.79-fold greater risk (CI 1.22-2.64) of problematic self-regulatory behavior, according to parental report. Among girls, similar results were evident at ages 4 and 5 (e.g., adjusted odds ratios for 4-5 h daily viewing versus 1-2 h at age 4: 2.59; 95 % CI 1.59-4.22). Video games may have a protective effect on the risk of problematic self-regulatory behavior at ages 3 and 5. Conclusion Longer daily exposure to TV during early childhood (age 4-5) may be associated with subsequent problematic child self-regulatory behavior.

TL;DR: In this article, the authors examine how information broadcasting through television (TV) media influences stock market activities and find that increased information flow via TV is significantly associated with greater trading volume and larger price change.
Abstract: This study examines how information broadcasting through television (TV) media influences stock market activities. Consistent with the effect of TV information to attract investor attention, we find that increased information flow via TV is significantly associated with greater trading volume and larger price change. Market liquidity (bid–ask spread) is improved for more TV information flows, suggesting that new information arrival in the market widens information asymmetry. As for information type, hard information from business-oriented programs and earnings-related news contributes to the attention effect of media compared with soft information. Finally, the impact of TV is more influential for stocks with more individual shareholders than those with institutional shareholders.

TL;DR: In this article, the authors analyze the circumstances surrounding pay-TV industry in Japan and conclude that although competitive video on demand services on the web are expanding gradually, the coverage rate of pay-tv remains stable in the Japanese market.
Abstract: The purpose of this paper is to analyze the circumstances surrounding pay-TV industry in Japan. According to SDL (Service Dominant Logic) theory, the paper considers the industry as a service ecosystem that is a self-adjusting system of components connected by service exchange. The study analyzes and illustrates the ecosystem using information from audience measurements by TV viewing meter and survey, media marketing research, economic statistics, observation of marketing activities and interviews with businesspersons in the industry. This paper argues that it is meaningful to consider the situations surrounding the pay-tv industry as a service ecosystem that consists of various components such as platforms, cables, satellites, channels, productions, TV sets, set top boxes, and family viewers. This consideration has to lead to a better understanding of the situation where each component is mutually nested. The paper concludes that although competitive video on demand services on the web are expanding gradually, the coverage rate of pay-tv remains stable in the Japanese market. The pay-tv ecosystem embraces strength to survive in the market for the moment due to attributes of audience and its prevention system against churn.
