加入WTO与中国烟草企业的股份制改革

烟草业在中国的国民经济中具有重要的地位 ,其发展对中国经济的影响不言而喻。从总体上看 ,中国烟草业现阶段已形成相对庞大的产业规模和较为完整的产业体系 ,产品也有一定的市场竞争力。但业内人士认为 ,在繁荣的背后 ,中国烟草业在迎接国内市场国际化的竞争中显得十分脆弱 ,国际竞争力令人担忧。本文针对入世带来的新问题、新形势 ,从经济和法律的角度对烟草企业的股份制改革的必要性进行分析 ,结合国内外股份企业发展的实践论证烟草企业进行股份制改革的可行性 ,并建议以红塔为试点对国内烟草大企业的进行股份制改制 ,通过设立烟草股份公司发行股票上市 ,吸纳资金 ,壮大企业规模 ,以构造我国烟草业的航空母舰 ,抵御外来竞争的压力。     

Depression,anxiety, and tobacco use: Overlapping impediments to sleep in a national sample of college students

ABSTRACT

Objectives: To examine how tobacco use and depression/anxiety disorders are related to disturbed sleep in college students. Participants: 85,138 undergraduate respondents (66.3% female, 74.5% white, non-Hispanic, ages 18–25) from the Spring 2011 American College Health Association–National College Health Assessment II database. Methods: Multivariate analyses of tobacco use (none, intermediate, daily) and mental health (diagnosed and/or symptomatic depression or anxiety) were used to predict sleep disturbance. Results: Daily tobacco use was associated with more sleep problems than binge drinking, illegal drug use, obesity, gender, and working >20 hours/week. Students with depression or anxiety reported more sleep disturbances than individuals without either disorder, and tobacco use in this population was associated with the most sleep problems. Conclusions: Tobacco use and depression/anxiety disorders are both independently associated with more sleep problems in college students. Students with depression and/or anxiety are more likely to be daily tobacco users, which likely exacerbates their sleep problems.     

Cigarette Smoking Among Korean International College Students in the United States

Abstract

Objective and Participants: This study explored (1) the prevalence of cigarette smoking among South Korean international college students in the United States, (2) differences in smoking between on- and off-campus living arrangements, and (3) predictors of an increase in smoking over time in the United States Methods: An online survey was completed by 1,201 students at 52 4-year US universities (34% response rate). Results: The overall smoking prevalence was 43.5%. The smoking rate (29.0%) of female students was higher than that (4%) of female college students in South Korea. Sex, living place, living situation, length of stay as a student in the United States, home smoking rules, campus-wide tobacco-free policies, and levels of acculturative stress, anxiety, and depression were significantly associated with an increase in smoking (p < .05). Conclusions: Given the high smoking prevalence among the South Korean students on US college campuses, targeted prevention efforts for these students may be warranted.     

A Systematic Analysis of College Substance Use Policies

College substance use policies provide guidelines for student behavior and influence campus culture. Although they are the primary environmental strategy to address campus substance use, policies have not been systematically compared and studied. We constructed a systematic review method to examine the accessibility, comprehensiveness, enforcement procedures, and clarity of college substance use policies. We developed an objective evaluation scheme for each of these 4 dimensions and then applied it to documented substance use policies from a sample of colleges and universities (N = 24). Policies were found to vary considerably but tended to specify compliance with local laws and emphasize student health and well-being. The next stage of campus policy review should examine actual implementation, evaluate potential differentiating factors among institutions, and assess the influence of policy on campus climate and student outcomes.     

Developing a Personal Program for Continuing Education

Abstract

The increasing number of field expeditions studying or working abroad each year is currently unparalleled by medical research efforts or data from which health professionals can make meaningful recommendations about how to keep personnel in the field healthy. The medical planning, organizing, and data are presented from a geology expedition to Guatemala involving 25 persons. Only minor medical problems were encountered, and less than 1% of the total person days at risk were lost due to illness. Eight guidelines are presented as a tool to assist any health professional in the planning and preparing of a team for the field.
