Factors Associated with Physician Discussion of Health Behaviors with Adolescents

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

我国当代社会泛政治化因素分析

我国当代社会具有明显的“泛政治化”倾向。“泛政治化”是一种缺乏政治理性的行为,它妨碍了正常的政治发展,使人们对社会问题不能做出实质的理解和处理,也使社会功能难以正常发挥,还常常带来政治冷漠。我们应当摈弃“泛政治化”的思维模式,构筑政治的理性主义,按照社会发展的规律来处理政治、经济、文化、体育、司法、教育等等的关系,以积极理性的心态来开展政治参与。

THE STATE SOCIALIST WELFARE SYSTEM and the POLITICAL ECONOMY OF PUBLIC HOUSING REFORM IN URBAN CHINA

This aticle analyses China's housing reform against the background that a new housing policy has been implemented since 1988. The crucial point of the 1998 housing policy package is to stop the allocation system of state‐subsidized public housing. By changing this rule of the game, a major institutional obstacle to housing reform will be removed, and some unfeasible policy measures become feasible within the new institutional context.     

Self-imposed term limits

In “Reconciling voters' behavior with legislative term limits,” Dick and Lott argue that since more senior representatives are better at rent-seeking, there is an inefficient tendency to re-elect incumbents. In their model, term limits are preferred collectively by constituencies, even though no constituency would independently oust its incumbent representative. However, many term limits are unilaterally self-imposed (in particular the 22nd amendment limiting presidents' terms to two), and their model cannot explain these limits. In this comment, I suggest that term limits may be self-imposed by risk-averse voters, who prefer cycling between left and right wing candidates to a once-and-for-all election that imposes a candidate of a single ideology on the entre electorate. The market failure that makes term limits helpful is that out of power minorities cannot bribe the median voter.     

Chinese nationalism,Taiwan autonomy and the prospects of a larger war

In contrast to the belief that the 1995–1996 Taiwan Straits crisis was caused by the visit of the President of Taiwan to Cornell University, in fact, the post‐Mao ruling groups in Beijing made forcing early reunification with mainland China on Taiwan a top priority soon after assuming power in 1978. This new focus on Taiwan's reunification reflects a policy switch. It is not a continuation of Mao era policies. The switch is basic. It involves a profound change in the content of Chinese nationalism from Mao era nationalism, which is seen by its critics in China as insufficiently promoting the national interests of the Chinese people. The new, post‐Mao nationalism in China not only challenges Taiwan's autonomy, it also could endanger peace in the Pacific‐Asia region. Consequently, it is important to rethink the political dynamics at work in China and in the region if the parties involved hope to avoid a larger war.
