Sexual behavior of resident street prostitutes with their clients in Camden,New Jersey

This paper describes a prospective study of the sexual behaviors of 20 resident street prostitutes and their clients. Prostitutes were long‐term residents of and practiced street prostitution in their community. They worked full‐time and reported averages of four clients per workday, four to five workdays per week, in an eight‐year career. Sexual behaviors with clients on five to eight workdays were recorded over a seven‐month period. Forty‐nine percent of contacts were with repeat clients. A regular client was defined by prostitutes as one who visited at least once a week. The results of the present study indicate that long‐term sexual relationships exist between some clients and prostitutes. Typically, a regular client had one to three sexual encounters per week with the prostitute, spent several hours with her at a motel (or one of their homes), and was more likely (than the occasional client) to engage in vaginal intercourse. Reported condom use was in the range of 39 to 74 percent.     

Generalized order statistic processes and Pfeifer records

We introduce a uniform generalized order statistic process. It is a simple Markov process whose initial segment can be identified with a set of uniform generalized order statistics. A standard marginal transformation leads to a generalized order statistic process related to non-uniform generalized order statistics. It is then demonstrated that the nth variable in such a process has the same distribution as an nth Pfeifer record value. This process representation of Pfeifer records facilitates discussion of the possible limit laws for Pfeifer records and, in some cases, of sums thereof. Because of the close relationship between Pfeifer records and generalized order statistics, the results shed some light on the problem of determining the nature of the possible limiting distributions of the largest generalized order statistic.     

Analysis of Order Statistics from Distributions with Regularly Varying Tails

In this article, necessary conditions for comparing order statistics from distributions with regularly varying tails are discussed in terms of various stochastic orders. A necessary and sufficient condition for stochastically comparing tail behaviors of order statistics is derived. The main results generalize and recover some results in Kleiber (2002 Kleiber, C. (2002). Variability ordering of heavy-tailed distributions with applications to order statistics. Statist. Probab. Lett. 58:381388.[Crossref], [Web of Science ®] , [Google Scholar], 2004 Kleiber, C. (2004). Lorenz ordering of order statistics from log-logistic and related distributions. J. Statist. Plann. Infer. 120:2004.[Crossref], [Web of Science ®] , [Google Scholar]). Extensions to coherent systems are mentioned as well.     

Statistical choice of extreme value domains of attraction — a comparative analysis

In recent years there has been a significant development of several procedures to infer about the extremal model that most conveniently describes the distribution function of the underlying population from a data set. The problem of choosing one of the three extremal types, giving preference to the Gumbel model for the null hypothesis, has frequently received the general designation of statistical choice of extremal models and has been handled under different set-ups by numerous authors. Recently, a test procedure, referred by Hasofer and Wang (1992), gave place to a comparison with some of other connected perspectives. Such a topic, jointly with some suggestions for applicability to real data, is the theme of the present paper.     

普通初中以奖学奖教构建和谐向上的人文学风和校风

初中短短的三年却是人生的一个较为重要的转折期和塑造期,这个阶段的学生很容易受到来自老师和同学们或褒或贬,促善或流俗的成长影响。所以要让普通初中每一个学生顺利而烂漫地度过他们的花季,必须构建一个和谐向上的人文化的学风和校风。根据初中生的身心特点和教育规律,汲取传统教育和地方文化的优势,我们拟以一所普通初中作为范例,进行奖学奖教人文学风和校风建设探索。
