关于整数的两类加权幂和(英文)

本文研究了n个自然数的m农幂分别以与（k=1，2…，n）为权的两类加权和。文中给出了和式的形式较为简单的递推公式；利用第二类Stirling数求出了和式的一般闭型表达式；同时，研究了和式的结构特征，并由此给出了和式的某些整除性质．     

论有限责任公司股东优先购买权的权利界定

为维护有限责任公司股东间的信赖利益 ,我国公司法赋予了股东优先购买权。该规定表面上看似具体 ,但实务中出现的新情况却使其出现了适用上的疑义———其他股东能否对欲转让的股权中的一部分而非全部行使优先购买权 ?作者从立法本意和法理角度进行分析得出 ,股东行使优先购买权的条件———同等条件 ,应既包括同等价格又包括同等数量 ,股东不能对欲让股权中的部分行使优先购买权。只有在立法上坚持这一价值取向才能最大限度地平衡老股东、出让股东和第三人之间的利益 ,从而实现立法意图和目的     

Statute Definitions of Elder Abuse

ABSTRACT

Older women victims of violence by a partner or family member are more often categorized as victims of elder abuse, not victims of family violence. Their needs are assessed, if at all, by social and health service agencies, often with little knowledge or understanding of domestic violence, while domestic violence policy initiatives, advocacy, and services focus on younger women and children. A survey of domestic violence services in British Columbia and the Yukon found that women over 60 years of age were a very small fraction, generally less than two percent, of women served, and those 50 to 59 years of age were also substantially under-represented. Only four percent of respondents had special services for older women. Comments from respondents confirm that abused older women face enormous difficulties in trying to establish a safe and secure future. It was also evident that better interaction is needed between those providing support and advocacy for abused women, and those who provide health and social services for older persons. A majority of the shelters provided community education to a wide range of agencies. Most have only partial accessibility to women with mobility handicaps.

论中国诗歌中的析数艺术

修辞学里设有"析字"一格,在诗歌里有一种与之相似的数字运用现象,本文姑且称之为"析数".枯燥的数字与诗人之情相碰撞,诗美学的瑶圃里又多了一颗璀璨的明珠.     

A law of large numbers for the scaled age distribution of linear birth-and-death processes

It is shown that certain measure-valued stochastic processes describing the age distribution of particles whose development is controlled by linear critical birth-and-death processes converge in distribution to a deterministic positive bounded measure.     

基于模糊层次分析法的军品供应商选择体系研究

针对我国的现实国情与军情,同时考虑到信息化战争后勤保障的发展趋向,建立了基于供应链的军品供应商选择指标体系,该体系可为当前的军事订货与采购制度改革提供一定的参考和依据;利用模糊层次分析法制订了军品供应商的选择方法,其中提出了一种新的三角模糊数排序的可能度指标,并将其与现有的可能度指标进行了比较;最后用计算实例对建立的选择方法进行了验证。     

英汉数字的文化差异

作者认为国际间在科技、贸易、经济等各方面的合作与交往都与文化不可分。数字作为一种文化现象存在于各种语言,但其在各种语言中的使用、表达等却不尽相同。作者从跨文化学角度出发,对英汉数字的文化差异进行了以下探讨:(1)英汉数字表示法差异;(2)英汉数字所表示的含义差异;(3)数字的联想及其跨文化差异。比较研究了其间的差异,指出了数字文化在跨文化交际中的重要作用。     

Recommendations on the Testing and Use of Pseudo-Random Number Generators Used in Monte Carlo Analysis for Risk Assessment

Monte Carlo simulation requires a pseudo-random number generator with good statistical properties. Linear congruential generators (LCGs) are the most popular and well-studied computer method for generating pseudo-random numbers used in Monte Carlo studies. High quality LCGs are available with sufficient statistical quality to satisfy all but the most demanding needs of risk assessors. However, because of the discrete, deterministic nature of LCGs, it is important to evaluate the randomness and uniformity of the specific pseudo-random number subsequences used in important risk assessments. Recommended statistical tests for uniformity and randomness include the Kolmogorov-Smirnov test, extreme values test, and the runs test, including runs above and runs below the mean tests. Risk assessors should evaluate the stability of their risk model's output statistics, paying particular attention to instabilities in the mean and variance. When instabilities in the mean and variance are observed, more stable statistics, e.g., percentiles, should be reported. Analyses should be repeated using several non-overlapping pseudo-random number subsequences. More simulations than those traditionally used are also recommended for each analysis.
