基于Vague集和属性综合评价的股票投资价值分析方法

对二级市场上同一行业内的不同股票进行投资价值分析是一个系统综合评价问题。本文从评价指标的选择、单项指标的评价、多项指标的综合评价和属性识别准则四部分来阐述属性测度理论在股票投资价值分析中的应用。特别需要指出的是,股票投资价值评价指标体系的建立和指标权重的确定应用了Vague集的理论和方法。最后,我们应用属性综合评价方法对电子元器件制造业的公司股票进行投资价值分析,结果验证了该方法的实用性和正确性。     

萨特的"整体性"、"整体化"概念和他的"人学辩证法"

萨特认为,辩证运动来源于个体的多元复合的总体的"整体化","辩证法"应该是在人的个体实践的"整体化"活动中来理解."整体性"是经验可理论的个体实践的多元复合性关系及其结构的总体关联性,它是"整体化"的结果,也是"整体化"运动中具有惰性作用的暂时的调节性因素,它体现着个人的各种关系和结构,是可以通过触景生情的联想而予以把握的."整体化"是人的不断发展的多元复合性关系的实践及其过程,另方面它也是实践场域的运动,并且,这二者是相互规定和制约,使个人及其实践始终面向未来,从而构成历史的辩证法;同时,"整体化"也就是人的最根本的存在.个人是历史的施动者,同时他也是被整体化者.所以在萨特看来,辩证法也就是"人学辩证法".     

Weight Loss Practices and Body Weight Perceptions Among US College Students

Objective: The authors assessed associations between body weight perception and weight loss strategies. Participants: They randomly selected male and female college students (N = 38,204). Methods: The authors conducted a secondary data analysis of the rates of weight loss strategies and body weight perception among students who completed the National College Health Assessment survey. Results: Half of respondents (50%) were trying to lose weight, although only 28% of students were overweight or obese. Also, 12% of respondents had inaccurate body weight perception. Women and men with inaccurate body weight perception were significantly more likely to engage in inappropriate weight loss strategies than were those with accurate body weight perception. Of all students attempting to lose weight, 38% used both diet and exercise. Conclusions: These data show that college students are interested in weight loss and that body weight perception plays an important role in the desire to lose weight.     

辽中北洼锦州A 区东营组浊积扇地震描述研究

针对渤海油田辽中北洼锦州A 区东二下段不同类型浊积扇内部反射结构及其地震响应特征认识难度大的问 题，开展了浊积扇地震描述研究。从浊积扇形成机理出发，根据围区钻遇浊积扇体不同部位探井的相应井段的岩性及 组合结构等典型特征，对不同浊积扇沉积亚相的沉积特征、岩性结构、测井和地震响应特征进行了系统的分析和描述。 在此基础上，建立不同类型浊积扇模型进行地震正演模拟，并对其地震响应特征进行了深入研究，最后利用地震多属 性预测技术对浊积扇的内幕进行了精细地刻画。预测了辽中北洼锦州A 区东营组浊积扇有利储层发育部位，研究结 果对该区浊积扇岩性油气藏勘探具有指导意义。     

财产保险火灾风险评价方法与标准制定的研究

财产保险火灾风险评价方法及其标准的制定在我国处于空白状态。根据安全系统工程学的思想，提出了基于财产保险的建筑火灾风险评价指标体系的建立方法，利用层次分析方法确定各指标的权重，并根据科学性和操作性的原则对指标的评价尺度进行了划分；在此基础上得出了建筑火灾风险综合分值评分表和核保和费率浮动方法。结果表明:利用层次分析方法确定各指标权重的方法是比较科学的，权重分布比较符合实际情况。结果显示:基于安全系统工程学思想的方法，可以为火灾保险国家标准的制定提供帮助。     

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.

Anderson's classification statistic based on a post-stratified training sample

The performance of Anderson's classification statistic based on a post-stratified random sample is examined. It is assumed that the training sample is a random sample from a stratified population consisting of two strata with unknown stratum weights. The sample is first segregated into the two strata by post-stratification. The unknown parameters for each of the two populations are then estimated and used in the construction of the plug-in discriminant. Under this procedure, it is shown that additional estimation of the stratum weight will not seriously affect the performance of Anderson's classification statistic. Furthermore, our discriminant enjoys a much higher efficiency than the procedure based on an unclassified sample from a mixture of normals investigated by Ganesalingam and McLachlan (1978).     

Compensatory Weight Control Behaviors of Women in Emerging Adulthood: Associations Between Childhood Abuse Experiences and Adult Relationship Avoidance

Abstract

Objective: To examine correlates of compensatory weight control behaviors among women in transition between adolescence and adulthood. Participants: The authors recruited a sample of undergraduate women (N = 759) at a large northwestern university during the 2009–2010 academic year. Methods: Logistic regression was used to assess relations among childhood abuse, psychosocial functioning, adult dating relationship factors, and women's endorsement of compensatory weight control behaviors. Results: The final model reliably distinguished between participants who endorsed versus denied use of compensatory behaviors (χ²[5, N = 747] = 36.37, p < .001), with global psychosocial functioning and relationship avoidance accounting for the most variance. Conclusions: These findings illustrate the importance of considering childhood abuse histories and adult relationships while assessing young women's compensatory weight control behaviors.
