锅炉排污的重要性及方法探讨分析

工业锅炉在使用中由于锅水蒸发而残留下的水垢、泥渣及沉淀物和腐蚀产物其他有害物质,使受热面污染,使锅炉的安全和经济运行带来影响,严重者可能导致重大事故发生。本文就锅炉排污的概念、目的、意义、方式、控制方法、质量要求、排污率的确定及宏观控制进行阐述,使我们在今后的工作中能对锅炉排污引起足够重视,确保锅炉安全运行。     

乡村社会二元规则系统的共存与博弈——以外嫁女的村民资格为例

近年来，围绕外嫁女的村民资格，产生了很多冲突，有的甚至诉诸司法程序。在冲突中，维权的外嫁女，与以村委会为代表的其他村民，分别依据不同的规则系统为自己辩护，即国家正式的法律制度与乡村社会的父系传统。前者源于现代工业文明，后者源于中国传统的农业文明，它们的并存，型塑了中国社会，尤其是乡村社会秩序的基本特征。     

Guns and crime revisited

I focus on the effect of changes in public security (policing) on private security measures that potential victims can take. In particular, I look at the tradeoff between different types of private security measures – such as using or carrying guns, carrying less cash or keeping less valuables at home, and using burglar alarms or Lojack – and study how this tradeoff is affected by changes in public security. If private householders’ direct security expenses are strongly substitutable with public policing (e.g., for guns which may be more useful in badly policed areas), an increase in policing results in a drop in these expenses; it also results in carrying or keeping less cash (an indirect security measure which reduces the prize a criminal can seize). If, however, householders’ direct security expenses are “complementary” to policing in the sense that they are more effective when police response is rapid (e.g., for burglar alarms), more policing increases these expenses unless the efficacy of joint (public and private) security expenses on combating crime encounters very sharply diminishing returns; moreover, a rise in policing also induces carrying or keeping more cash. An increase in penalties increases the tendency to keep cash on hand, and also reduces crime, provided that as private precautions increase, with policing constant, it takes a larger increment in security spending to compensate for a specific drop in penalties. The results are consistent with some empirical trends in crime rates, policing, penalties and private precautions.     

A note on the connection between factorial series distribution and zero-truncated power series distribution

Summary

The main purpose of this note is to call attention to the close relationship between the problem of estimating the parameter of a zero-truncated power series distribution and the problem of estimating the parameter of an associated factorial series distribution. We also extend a known recurrence property for the Poisson case to the binomial and negative binomial cases.     

旅游策划创新中存在的问题及对策探讨

随着我国旅游产业的迅猛发展,各级政府和有关部门对策划与规划也日益重视,因而策划、规划从业人员越来越多,影响越来越大,竞争也日趋激烈。于是"创新"往往成为吸引眼球、击败对手、争取项目的制胜"法宝",创新的成败往往也决定着一个地区旅游业的兴衰和景区的生死存亡。不过,在创新策划与规划的过程中确实出现了不少问题,如:有关部门对策划与规划资质把关不严;盲目求大求洋;策划或规划项目与景区主题及文化内涵不协调;严重破坏资源和环境;评审流于形式等。针对这些问题,应相应地采取一些对策,如:严把资质关;严格遵守有关的法律法规;高度重视对策划从业者的培养和管理工作;严格遵循科学策划、科学规划的程序和原则;建立并严格执行全程监督和终身责任追究制度;严把评审关等。     

试论电子支付的立法完善

电子商务的一个重要问题是确保网络交易支付的安全性、有效性。保障电子支付活动的安全既是一个技术问题,更是一个法律问题。当前我国电子支付的立法严重滞后于金融电子化的步伐,研究和参照国际相关立法,完善我国该领域的法律规定已迫在眉睫。鉴于此,文中对此进行了探讨。     

新会计制度与现行税法的矛盾及对策研究

新会计制度与现行税法的矛盾表现在资产、负债、所有者权益、收入、成本费用支出等各个方面.由于新会计制度与税法施行的目的不同,所以这些矛盾将始终存在.为此,一方面应该同时执行两种法规,另一方面要采取措施尽量缩小两者的矛盾.     

海洋文化产业集群内在规律及发展思路探讨——以浙江舟山为例

海洋文化产业是文化产业中特殊的组成部分,是当代文化产业的一个前沿研究领域。本文运用理论研究和实地调查相结合的方法,列举舟山群岛鲁家峙、岱山东沙镇、普陀山、朱家尖、沈家门、长峙岛、蚂蚁岛、太阳谷、朱家尖白山、桃花岛等实际案例,从文化产业集群三大核心定律出发,即产业链组合与延伸的规律、区位优势与选择的规律、产业集聚与联动的规律,充分揭示了舟山群岛海洋文化产业集群的内在规律及发展思路,提出舟山应结合各个岛屿的资源禀赋特征,因岛制宜构建不同种类的海洋文化产业集聚区的建议,对于舟山群岛海洋文化产业集群发展具有一定的指导意义。     

RANDOM COEFFICIENT MODELS: THEORY AND APPLICATIONS

Abstract. This paper provides an overview of the rationale behind, and the implementation, and uses of, the random coefficient approach to econometric modelling. A simple random coefficient model is presented, and methods for estimating, testing, and validating such a model are described. A more general model is then presented. The general model is shown to include several fixed-coefficient models as special cases and can be estimated incorporating a variety of judgements concerning simplification. Finally, the paper reviews recent applications of random coefficient estimation.     

医患纠纷法律适用探析

近年来,对医患纠纷的法律适用问题,理论及司法实践中均存在争议,这既不利于化解日益尖锐的医患矛盾,也有碍于对医患双方利益的维护。在明确医患纠纷法律适用的前提条件、理论基础及关键的基础上,提出医患纠纷应适用《民法通则》《合同法》等民事法律规范调整;医患纠纷原则上应属于《消法》调整,但由于医疗服务的高风险性的特征,应予以区别对待。
