Conditional interval estimation of the mean following rejection of a two sided test

The effect of rejecting a two-sided preliminary test of significance for the mean of a normal distribution upon subsequent interval estimation of the mean is examined. For the case where the variance is known, conditional confidence intervals may be shorter than unconditional intervals, in contrast to the one-sided preliminary test case examined by Meeks and D’Agostino (1983, The American Statistician, 7, 134-136) . For the case where the variance is unknown and must be estimated by the sample variance, it is shown that customary intervals do not offer uniformly greater or lesser coverage than the nominal level.     

论《招魂》《九歌》的生命美学

屈原的《九歌》《招魂》通过生命本身的热烈追求 ,深情缠绵 ,豪奢享受 ,展示了一种“盛”美、“奢”美、“华”美、“豪”美。这在汉人精神和汉赋风格中得到了继承和发挥。在美学上 ,它所体现的精神实质是戏剧和宴会的 ,而不是典礼的 ;是音乐与舞蹈的 ,而不是文学的。在主要受儒道两家思想浇灌的中国文艺的历史上 ,这种崇尚强的生命力或生命强力的审美追求尤其可贵

Insecurity related to working life by age groups in Finland and Estonia in the 1990s

This article compares the reasons for insecurity related to working life in different age groups in Finland and Estonia, and the coping strategies evident in the two countries. Insecurity related to working life is more common in Finland than in Estonia. The differences between the two countries are more distinct with respect to experienced work-related insecurity than to an experienced lack of well-being linked to work. This shows that feelings of insecurity are affected not only by external factors, but also by internal factors linked to a person's earlier development. The most common causes of insecurity for people of working age are unemployment, mental strain and difficulties in interpersonal relationships at the work place. The individual's willingness to find means of coping at work is more clearly evident in Estonia than in Finland. People of working age in Finland are more likely to attempt to change the external conditions of work than are their Estonian counterparts.

A time series approach to life table construction

This paper deals with the construction of the life table. A discussion of basic facts about the life table is followed by the proposal of a nonstationary, autoregressive model for the life table. The moment structure of the nonstationary, autoregressive model is developed. Some estimation procedures are proposed followed by several examples.     

Why Aesthetic Patterns Matter: Art and a “Qualitative” Social Theory

This paper argues that an explanation of the role of aesthetic patterning in human action needs to be part of any “qualitative” social theory. It urges the social sciences to move beyond contextualism and to see art as visual, acoustic and other media that lead to heightened sensory perception and the coordination of feelings through symbols. The article surveys the argument that art provides a basic model of how the self learns to interact with external environments; and the complementary thesis that art could be seen as integral to the emergence of systems of human knowledge, communication and economy. Ornamentation and stylization are advanced as two concrete devices through which human attention is captured and experience is ordered through aesthetic patterns. The conclusion is drawn that art offers the social sciences a meaningful account of the perceptual or “qualitative” dimensions of social interactions; and that this is much needed today.     

Generation of multivariate distributions by vertical density representation

Troutt (1991,1993) proposed the idea of the vertical density representation (VDR) based on Box-Millar method. Kotz, Fang and Liang (1997) provided a systematic study on the multivariate vertical density representation (MVDR). Suppose that we want to generate a random vector X[d]Rⁿthat has a density function ?(x). The key point of using the MVDR is to generate the uniform distribution on [D]_?(v) = {x :?(x) = v} for any v > 0 which is the surface in RⁿIn this paper we use the conditional distribution method to generate the uniform distribution on a domain or on some surface and based on it we proposed an alternative version of the MVDR(type 2 MVDR), by which one can transfer the problem of generating a random vector X with given density f to one of generating (X, X_n+i) that follows the uniform distribution on a region in Rⁿ⁺¹defined by ?. Several examples indicate that the proposed method is quite practical.     

《文化哲学》与生态文明

《文化哲学》是施韦泽生前发表的一部最重要的哲学-伦理学著作,是中国读者了解施韦泽提出和论证敬畏生命伦理学的方法和过程,并且探讨其思想与当代生态文明关系的最好资料。《文化哲学》的文化批判是其文化哲学的起点,敬畏生命伦理学则是其文化哲学的结论。而施韦泽所体现的向东方思想的转向和跨越,使其原本还没有直接针对环境和生态问题的敬畏生命伦理学成为当代“生态伦理学革命“的先声,并由此成为当代生态文明的思想渊源之一。     

Exploring the Moderating Influence of Delinquent Peers on the Link Between Trauma, Anger, and Violence Among Male Youth: Implications for Social Work Practice

This study’s objective was to explore the influence of delinquent peer exposure, on the relationship between male youths’ histories of trauma, anger, and violent behavior. Using a nationally representative sample of male adolescents aged 12–17 and self report interviews, information was gathered on their levels of exposure to violence, stressful life events (SLE), anger, depression, delinquent peer exposure, and violent behavior. Results of a moderation analyses revealed that youth who reported higher levels of exposure to trauma, anger, and delinquent peers were at an increased risk for anger and for violent offending. Delinquent peer exposure exerted a significant interaction effect on the relationship between anger and violent offending. The implications for prevention and intervention efforts are delineated.
