A Trivariate Distribution for the Height,Weight, and Fat of Adult Men*

Using exploratory data analysis, probability plots, scatterplots, and computer animations to rotate and visualize the data, we fit a trivariate Normal distribution to data for the height, the natural logarithm of body weight, and the body fat for 646 men between the ages of 50 and 80 years as reported by the medical staff of the U.S. Veterans Administration's “Normative Aging Study” in Boston, MA. Although these data do not include any children, women, or young men, the measurements represent the best data that we could find through a 4-year search. We believe that these data are well measured and reliable for men in the specified age range and that these data reveal an interesting statistical pattern for use in probabilistic PBPK models.     

论《红岩》的“身体”革命意识

“身体”是解读《红岩》革命意识的一个重要的维度,从身体的命名、身体的出场仪表、身体的感知系统等身体的构成属性互证自明地凸显了敌、我两种不同的“身体阵营”。革命身体的受虐被演绎成了庄严的凯旋仪式与洗礼典礼。在红色狂欢的受难姿态中“身体”的痛感为一种信仰道义充斥的革命浪漫激情所替代。     

Predicting Severity of Foreign Body Injuries in Children in Upper Airways: An Approach Based on Regression Trees

The entry of a small item into the upper airways is one of the leading causes of injuries in children up to 14 years old. The aim of this study is to characterize types of objects causing choking along with the features of the children involved in the accident and compare results with current standards. The European Survey on Foreign Bodies Injuries Study (ESFBI) collected data on foreign body injuries from 19 European countries. The data from ESFBI were selected according to the ICD-9-CM codes 933 (foreign body in the pharynx and larynx) and 934 (foreign body in the trachea, bronchi, and lungs). Both a classification tree and a linear discriminant analysis (LDA) have been set up to predict the probability that an injured child experiences a hospitalization. The classification tree provides flowchart-type decision rules and allows for analyzing the impact of the item features, the children characteristics, and the circumstances of the accidents on the severity of the foreign body injuries. Results showed that children younger than 3.5 who are involved in an accident have a high probability to experience a hospitalization.

萧红小说中的身体之喻

萧红把自身身体的受损经验投射到文本中的女性生存上去，形成了独特的身体叙事，但这并没有让她具有真正的女性主义立场，反而因为过度依赖与沉溺于女性的身体受损经验而失去了女性性别定位，从而在经历性别冒险后陷入自我的迷失。

艺术的身体性本源——从身体出发解读尼采美学

尼采文本中隐含着一条思想的道路,即从身体出发,在身体敞开的维度内思考问题。身体为我们透视尼采的美学提供了这样一个视角:尼采是从艺术家这一身体性的存在者出发思考艺术的本源,他在艺术家的陶醉状态中揭示出作为创造力意志的权力意志。权力意志作为艺术的本源是身体性的,具体表现为人类学、生理学和心理学三个方面。     

对我国粮食双层流通市场运作机制的经济学解释

与大部分商品一样,现实中的粮食市场往往也是一个多层次的流通市场,其供求关系绝非一个简单的生产者与消费者之间的单层级的市场关系,而是一个包含着生产者、消费者以及多层经销商在内的复杂的市场往来关系.基于我国现阶段粮食市场双层流通体制运作的现状与具体特征,为进一步健全与完善我国的粮食流通体制,现阶段一方面有必要打破国有粮食企业对粮食购销市场的垄断局面和以力争形成竞争、活跃的粮食流通市场;另一方面也要积极培育全国性与区域性的粮食批发市场和积极利用市场机制来配置粮食资源,大力开展省际的产销协作,鼓励产区与销区建立起长期且稳定的购销关系,支持有奈件的企业从事粮食的进出口业务.
