运动队中根据简单血液生化指标间接推断运动员贫血种类的应用

体能类运动项目的运动员,尤其是女运动员经常出现贫血现象,较低的血红蛋白水平代表着较低的载氧能力,严重的影响了运动员的健康和教学训练。贫血分为多种类型,在运动员中发生的贫血有些由运动训练导致,称为运动性贫血,有些是由于生理原因造成的。如果不能针对导致贫血发生的原因对症治疗,无法有效的治愈贫血症状,本文力图通过举例与分析,给出推断不同种类贫血发生原因的方法,帮助运动员对贫血症状进行有效治疗。     

推拿按摩对运动性疲劳恢复的作用机理

目的：探讨中医按摩对消除运动性疲劳的作用。方法：采用随机对照实验,把100名大学体育专业的学生随机分成2组,一组运动疲劳后立即采用中医按摩方法（以下简称实验组）;另一组运动疲劳后采用休息的方法（以下简称对照组）。比较实验后两组中学生机体疲劳恢复所用的时间。结果：实验组采用中医按摩方法可以缩短了肌肉和血中乳酸清除的时间,缩短了运动性疲劳恢复的时间。结论：采用中医按摩对消除运动性疲劳有切实可靠效果,学生在运动后应做一些中医的按摩推拿。

对运动性猝死的现场急救及防控措施

<正>据中国体育报报道:2012年11月10日,在华中科技大学举办的秋季运动会上,女子3000米和男子5000米长跑项目被取消。后续报道中北京、西安等地部分高校也取消了长跑项目,原因都是学生体质差,无法坚持下去,担心在比赛中出现意外伤害事故。11月18日,广州举办的首届广州马拉松赛中,有两位参赛运动员发生猝死。相继发生的猝死和取消长跑项目比赛事件,引起了社会各界的高度关注。

A Reexamination of How Athletic Success Impacts Graduation Rates

A BSTRACT . Past research has found conflicting evidence concerning whether higher levels of athletic success positively or negatively impact college graduation rates. This paper intends to improve on past research by separating the graduation rate of student-athletes from all other undergraduates. Results using generalized least squared estimation and paired t-tests from a sample of Division I schools suggest that neither the graduation rate for student-athletes nor the graduation rate for all other undergraduates is sensitive to the level of a school's athletic success. However, the graduation gap between student-athletes and all other undergraduates is sensitive to various measures of a school's athletic success. Women have higher graduation rates than men in general, and this gender graduation gap is exacerbated when focusing on student-athletes at schools with the most prominent athletic programs.     

Threat appeals in social marketing: death as a ‘special case’

Death is commonly used as a threat, both by fear-appeal researchers and by social marketing and health promotion practitioners (eg ‘Quit smoking or you'll die’). Fear (or threat) appeal researchers have frequently used death to arouse fear, and particularly in the ‘high’ fear condition. It is argued here that death is a ‘special case’ threat, and that the introduction of death in high fear conditions is a confounder in that death is a qualitatively different negative outcome from the non-death negative outcomes used in low fear conditions. The use of death in threat appeals requires attention in its own right for a number of reasons. First, death will occur eventually regardless of the message recipient's behaviour. Hence, messages that threaten death may arouse defensive responses in the target audience (eg ‘you've got to go sometime’), and unresolvable anxiety in the general population. Secondly, death can vary on a number of attributes (eg age at death, sudden versus prolonged, etc), and, while most threat appeals imply premature death, few studies have made this point explicit. Thirdly, the fear of death is multidimensional and some dimensions are more readily acknowledged as fearful than others. For example, a threat specifying the effect of one's death on loved ones might have more impact than a threat of death to oneself. Fourthly, people may fear death differently, or, for religious or other reasons, may not fear death at all. Furthermore, there may be age and gender differences in response to threat appeals using death. It is concluded that systematic research is required to determine whether and for whom death threats are effective. Copyright © 1999 Henry Stewart Publications     

The revival of cities in medieval Europe: An application of catastrophe theory

In early medieval times, a great change came over Europe. One of its most noticeable aspects was the growth of cities which had been static or declining for centuries. This paper discusses the possibility that the growth was due to the fact that trade was gradually becoming easier. Using the notions of catastrophe theory, it is shown that even a slow improvement in communications could result in a sudden change in the nature of the system, with regions that had previously been unspecialized and self-contained changing over to active concentration on manufacturing or farming. The resulting improvement in living standard could explain the increase in total population which happened concurrently with the growth of the cities. A different explanation is also discussed: cities may have originally grown in response to the pressure of an independently increasing population. It is shown that in this case the growth patterns would be different, making it possible to test which of the two explanations is incorrect.     

Investigating differences between female and male athletic donors: a comparative study

• The purpose of the study was to identify differences between male and female donors of athletic programmes in order to improve fundraising effectiveness. Simple random techniques were used to gather data for the study.
• The total sample size was 387 from which 115 were female and 272 were male donors of the athletic programmes of a large eastern state university.
• The classification with discriminant analysis results showed that motives (priority seating and professional contacts), annual contribution, personal and household income, attendance of sport events and years of sport experience significantly discriminated between female and male athletic donors.
• The athletic fundraising practical implications are explored.

An estimation of NCAA Football Bowl Subdivision demand as a two‐part tariff

College football is one of the highest revenue generators for university athletic departments, and revenue from attendance is one of the major football revenue sources. This paper seeks to estimate the demand for Football Bowl Subdivision (Division I) college football using athletic department supplied financial information. I find that Football Bowl Subdivision athletic department's price spectator demand is consistent with two‐part tariffs.

Resource allocation, equity and public risk: Dying one at a time vs dying all together

This paper focuses on the evaluation, from an individual and societal perspective, of risk in terms of possible loss of life due to an exposure to two different types of events over a period of time. The two types are: risk of death from a catastrophic event (a sudden death of many people in a disaster at a yet unknown point in time) expected to occur during a planning period, or risk of death from another event (e.g. disease, road accident, etc) which claims fewer lives each year. but for which the expected total number of deaths over the planning period is equal to the expected number of deaths from the catastrophic event. Our analysis considers the extreme case in which these two types of events have the same probabilities of death every year and the same expected number of fatalities over the planning period. The individual's decision problem is described using a von-Neumann Morgenstern (vNM) utility function. The model suggests that the choice between these types of events depends on the value of the following variables: the probability of death over the planning period, the length of the planning period, the individual's time preference pattern, and the utility of being in different anxiety states. Stochastic extensions that may direct the public decision making process (involving aggregated preferences) are discussed. We also discuss issues of implementation.
