Television (TV) food advertising has attracted criticism for its potential role in promoting unhealthy dietary practices among children. Content analyses indicate junk food advertising is prevalent on Australian children's TV; healthy eating is rarely promoted. This paper presents (a) a cross-sectional survey examining associations between children's regular TV viewing habits and their food-rel...

This study examined the associations between perceived neighborhood and home environmental factors and excessive television (TV) viewing time among Taiwanese older adults. The sample data was collected by administering computer-assisted telephone interviewers to 980 Taiwanese older adults (aged ≥ 65 years) living in two regions. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculat...

Internet TV is a convergent appliance from TV and desktop PC with Internet. Since TV and desktop PC have many different characteristics, so two major questions would be raised. The first question is which one of two media will be the dominant anchor across the three domains of Internet businesses; contents, community, and commerce. The second question is how the total value of convergence will ...

OBJECTIVE Evidence suggests that TV viewing is associated with body mass index (BMI) and metabolic syndrome (MetS) in adolescents. However, it is unclear whether dietary intake mediates these relationships. METHODS A cross-sectional analysis was conducted in adolescents (12-19 years) participating in the 2003-2006 United States National Health and Nutrition Examination Survey. BMI z scores (z...

We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. For U.S. cable-television markets between 1997-2006, we find that prices are 33% to 74% higher and qualities 23% to 55% higher than socially optimal. This “quality overprovision” contradicts classic results in the literature and our analysis suggest that it is a direct result of the presence of ...

This article is an extension for 2-D analogue signals (and more) of the methods presented in “A nearly One-to-One Method to Convert Analog Signals into a Small Volume of Data” which was published in an earlier issue. This new conversion method may save the storage space, the bandwidth of the transmitting channels and the necessary energy for transmission. It may be particularly interesting for ...

Playing TV game shows such as Jeopardy or Survivor in the classroom can be fun. But does it improve student understanding of course concepts? To find out, the author conducted eight experimental trials in five separate undergraduate information systems classes. Although he found limited improvement in student learning, the author’s experiences with the game and the results of a student survey w...

Using a time-diary, the authors asked 935 undergraduate college students to report on their multitasking habits while engaged in four main activities: reading for fun, watching TV, reading for school purposes, and using the Internet. The authors examined student data to find out (a) whether their multi-tasking habits vary significantly by college classification and (b) whether they felt the tim...
