Body posture in elderly,physically active males

The objective of this study was to evaluate the shape of anterior–posterior curvatures of the spine and to determine the values of body symmetry deviations in the frontal plane, in elderly males. The study group consisted of 34 males aged between 61 and 83 years, attending two hour-long training sessions a week. The comparative group consisted of 30 students. The photogrammetric method based on the Moire phenomenon was used to evaluate the body posture. The obtained data confirm characteristic tendencies of physiological spinal curvatures to change with the aging process. A decrease of the lumbar–sacral spinal-segment inclination and an increase of the upper thoracic spinal-segment inclination were observed in the elderly males. Whereas, the value of thoracic kyphosis lower-segment inclination was similar to the value obtained in young adult males. The stated differences indicate a flattening of lumbar lordosis and a deepening of the upper arch of thoracic kyphosis, which results in a characteristic body posture in the standing position with the head protruding and the upper trunk segment inclined. The above-mentioned observations indicate a dominance of the angular thoracic kyphosis value over the remaining spinal curvatures. These differences occur to a greater degree in elderly males.     

The Generalized Pascal Triangle and the Matrix Variate Jensen-Logistic Distribution

This article defines the so called Generalized Matrix Variate Jensen-Logistic distribution. The relevant applications of this class of distributions in Configuration Shape Theory consist of a more efficient computation, supported by the corresponding inference. This demands the solution of two important problems: (1) the development of analytical and efficient formulae for their k-th derivatives and (2) the use of the derivatives to transform the configuration density into a polynomial density under some special matrix Kummer relation, indexed in this case by the Jensen-Logistic kernel. In this article, we solve these problems by deriving a simple formula for the k-th derivative of the density function, avoiding the usual partition theory framework and using a generalization of Pascal triangles. Then we apply the results by obtaining the associated Jensen-Logistic Kummer relations and the configuration polynomial density in the setting of Statistical Shape Theory.     

Body Dissatisfaction in Midlife Women

ABSTRACT

We examined the extent and correlates of body dissatisfaction among 1026 54-year-old women from the MRC National Survey of Health and Development. Weight dissatisfaction was reported by nearly 80% of the sample and by over 50% of ‘normal weight” women (BMI < 25). Women indicated being most dissatisfied with their bodies currently, relative to their younger years, including their forties. Adjusting for BMI, dissatisfaction was highest in higher social class women and in those who rated themselves in poorer health. Women with poor body esteem, regardless of body size, were likely to avoid various everyday situations because of how they felt about their bodies. Adjusting for BMI, women who were happy with their weight were more likely to report distress about other aspects of their appearance. We suggest that body dissatisfaction in women of this age group merits further attention.

Simulation for the complex Bingham distribution

The complex Bingham distribution is relevant for the shape analysis of landmark data in two dimensions. In this paper it is shown that the problem of simulating from this distribution reduces to simulation from a truncated multivariate exponential distribution. Several simulation methods are described and their efficiencies are compared.     

“文革”农村小说：女性命运观照及伦理探索

"文革"农村小说对"社会主义"伦理道德的探索,是通过对如下几种女性命运进行观照而完成的:一种是出身于没落地主、富农家庭,在婚姻、"贞节"、生育等方面饱受封建伦理道德摧残的人格萎缩型女性;一种是经受过旧社会的煎熬,但在新社会终于获得了新生的妇女;还有一种是长在红旗下的年轻人,她们"家庭出身好,文化程度高,又有丰富的斗争实践经验",因而成为无产阶级革命事业当然的接班人。     

高中生的体型认同:基于女性的分析视角

从身体社会学来看,女性的体型审美取向是男权文化的典型表征。通过中日韩三国高中生的对比分析发现,与男生相比,高中女生普遍接受"以瘦为美"的体型观,存在更为严重的体型认同问题:在主观体型认知上,倾向于"向胖认同";在体型认同情绪上,表现为对"胖"不满:在体型认同策略上,以饮食减肥为主。这表明,身体焦虑已蔓延到了高中生群体,导致高中女生中存在着较为明显的体型认同偏差和盲目减肥现象。究其原因,传媒的渲染与强化起的是主导作用,家庭教养和同辈交往也有间接影响。     

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.
