Television,teenagers, and health

The purpose of this study was to determine the extent to which multiple health and lifestyle variables differ among 406 adolescent males classified according to average duration of daily television viewing. Cattell's 16PF Questionnaire, Form C, and Rosenberg's Self-Esteem Scale were employed to assess psychological health, and the Physical Performance Test for California was used to measure six dimensions of physical fitness. Participants also completed a questionnaire requesting general demographic data, and information regarding lifestyle and average amount of time spent watching television per day. Results indicated that the well-being of the boys was related significantly to the extent of television viewing. Light television viewers were more physically fit, emotionally stable, sensitive, imaginative, outgoing, physically active, self-controlled, intelligent, moralistic, college bound, church oriented, and self-confident than their counterparts, especially heavy television viewers. Furthermore, light television viewers were less troubled, frustrated, and shrewd, and used drugs less frequently, particularly alcohol, than moderate and heavy television watchers, especially the latter.Larry Tucker, Associate Professor, received his Ph.D. from Southern Illinois University-Carbondale in Health Education. His research interests include adolescent health behavior, particularly self-destructive behaviors and achieving high-level wellness.     

A salt on the land: A narrative analysis of the controversy over irrigation-related salinity and toxicity in California's San Joaquin Valley

A narrative network analysis of the seeming paralysis of efforts to deal with the problem of toxic elements in agricultural drainage in California's San Joaquin Valley shows irrigation agencies to be caught in a dilemma. Despite pressures to reduce uncertainty about treatment methods, reducing this uncertainty risks increased political polarization over agricultural subsidies. As a result, policy-makers are reluctant to move in any action-forcing direction, and continue to order further studies. We sketch out those areas of contention that must be addressed if real progress is to be made, demonstrating that the issues are primarily organizational and political rather than technical. We also discuss our experience in presenting these findings, along with our recommendations for structural separation of drainage functions from present irrigation agencies, to the relevant policy audience.     

It's About Time: The Lifespan of Information Effects in a Multiweek Campaign

I advance a theoretical and empirical framework that puts time and thus the temporal dynamics of candidate evaluation front and center in order to advance our understanding of the lifespan of information effects while enhancing the external validity of our experimental approaches. With these temporal properties in mind, I designed a “panel experiment” with research conducted over 12 weeks. This represents the first experimental approach to combine control over information exposure with attention to information processing throughout the course of a multiweek campaign. Against the backdrop of partisanship, empirical tests assess the ability of transient exposure to issue and character information to produce effects that endure beyond the moment the information is encountered either via memory‐based or on‐line processes. Findings reveal a remarkably limited role for enduring information effects and suggest a “rapid displacement” model of information processing where new information quickly displaces the accumulated stockpile of old information.
