Normal approximation to the hypergeometric distribution in nonstandard cases and a sub-Gaussian Berry–Esseen theorem

In this paper, we consider simple random sampling without replacement from a dichotomous finite population. We investigate accuracy of the Normal approximation to the Hypergeometric probabilities for a wide range of parameter values, including the nonstandard cases where the sampling fraction tends to one and where the proportion of the objects of interest in the population tends to the boundary values, zero and one. We establish a non-uniform Berry–Esseen theorem for the Hypergeometric distribution which shows that in the nonstandard cases, the rate of Normal approximation to the Hypergeometric distribution can be considerably slower than the rate of Normal approximation to the Binomial distribution. We also report results from a moderately large numerical study and provide some guidelines for using the Normal approximation to the Hypergeometric distribution in finite samples.

Estimating the distribution of one-dimensional discrete scan statistics viewed as extremes of 1-dependent stationary sequences

Discrete one-dimensional scan statistics can be viewed as extremes of 1-dependent stationary sequences. A result of Haiman [1999. First passage time for some stationary processes. Stochastic Process. Appl. 80, 231–248] provides approximations of the distributions of extremes of 1-dependent stationary sequences together with sharp bounds for the corresponding errors. We apply this result to scan statistics generated by Bernoulli r.v.'s and to the charge problem.

完善非法侵入计算机信息系统罪的几点思考

非法侵入计算机信息系统罪是信息时代产生的一种新型犯罪，我国刑法第285条对此作出规定。然而，该罪在罪名、犯罪客体和对象、犯罪主体、刑种和量刑、刑事管辖权等方面都存在一些立法缺陷。因此，从立法层面应规范罪名的表述．适当扩大犯罪对象的范围，增加单位犯罪主体．增加本罪的刑种，提高本罪的刑度，明确本罪的刑事管辖权。

‘Ass‐kicking’ Women: Doing and Undoing Gender in a US Livestock Auction

Using in‐depth interviews with farm operators and participant observation at a livestock auction, this article explores how women in conventional agriculture in the USA ‘do gender’ in a male‐dominated world. In particular the ways that space, both public and private, alters the performance of gender are analysed. Given that agriculture in the USA has traditionally been tied to masculinity and that more and more women are entering the field, the article examines the strategies women employ to negotiate the tension between being women and being farmers. The findings suggest that in general women's success is intricately tied to their ability to reproduce the masculinity that spells success for their male counterparts. These women dress in masculine clothing, swear and are ‘tough as nails’. Furthermore, women's mere presence as farm operators does not necessarily subvert the relationship between masculinity and agriculture. In many ways this notion is reinforced by the presence of these women and so the performance of gender ultimately reinforces rather than subverts the ties between hegemonic masculinity and agriculture.     

中东油气与中国石油发展的战略思考

在当前国际环境下,中国的石油安全战略应是开放和外向型的,其核心思想是“保内争外”,即中国政府应进一步加强对中国石油企业参与国际能源合作的宏观指导和支持;中国石油企业应加强国内油气资源的可持续开发和利用,坚持开展国际能源合作,直面国际博弈。中东国家油气资源丰富,且与中国关系友好,应是中国石油企业对外开展能源合作的首选地区。
