Preventing HIV in injection drug users: exploring the tradeoffs between interventions

Injection drug users (IDUs) transmit the human immunodeficiency virus (HIV) via both needle sharing and sex. Available interventions for this population have varying costs and effectiveness and focus on different risk behaviors. In this analysis, we look at two interventions. One is inexpensive, broad-based and provides modest risk reductions (street outreach (SO)); the other is narrowly focused, expensive and relatively effective (methadone maintenance). This analysis explores the effects of population risk behavior, intervention effectiveness, intervention costs, and decision constraints when allocating funds between these two interventions to maximize effectiveness. We develop a model of the spread of HIV, dividing IDUs into susceptibles (uninfected) and infectives, and separately portraying sex and injection risk. We simulate the epidemic in New York City for time periods from the mid-1980s to the early 1990s, and incorporate the behavioral effects of two interventions performed singly or in combination to find the allocation that maximizes the number of infections averted in the IDUs and their noninjecting sex partners, assuming interventions have increasing marginal costs. We find that the optimal allocation nearly always involves spending the maximum allowable amount on SO. This result is largely insensitive to variations in risk parameters, intervention efficacy, or cost. The model's structure, however, makes clear that many factors contribute to this insensitivity, namely the scope of the interventions, the dual drug/sex nature of HIV risk in the population, the asymmetry of sexual risk for men and women, and the potential benefits to nonIDUs.

最终控制人特征与上市公司现金股利政策

本文以2002年-2004年上市公司的股利分配数据,实证检验了最终控制人的特征对上市公司现金股利政策的影响.结果表明.上市公司现金股利政策与最终控制人的侵害动机成反比,现金股利的支付率随着最终控制人控制权比例的增加呈先减少后增加的U形变动;两权分离程度越小,派发现金股利的水平就越大,但这种影响主要来自于较高的现金流量权,现金流量权比例越大,派发现金股利的概率和水平也越大;最终控制人性质为政府尤其是地方政府时,上市公司派发现金股利的概率和水平更高.

融资约束与公司投资关系研究综述

公司的融资约束和投资-现金流量敏感性之间的关系成为财务管理的焦点问题。本文通过对国内外融资约束与投资关系众多文献的分析,研究了融资约束的影响因素,探讨了不同情况下融资与投资的关系,并分析了现存的投资-现金流敏感性模型的应用现状。最后,对我国进行投资-现金流敏感性问题的研究提出了建议。     

第三方物流管理系统设计

物流管理软件在我国市场具有巨大的应用前景。由于我国企业的物流支出成本过高、管理水平落后，所以物流服务业市场潜力很大。物流管理软件的出现成为物流业发展的必然。然而，现在出现的各种物流管理软件很多存在自身的弊端和局限性。因此能设计出一个功能比较完备且经济、实用的物流管理系统迫在眉睫。本文主要对第三方物流管理系统的各种功能进行了论述和说明。     

西部民族地区新农村建设中的特色经济与特色人力资源开发研究

西部民族地区新农村建设,特色经济仍然是其必然选择,而特色经济的发展,特色人力资源的开发是有效途径.在西部民族地区农村人力资源开发中,存在着重视程度不够、开发基础薄弱、开发机制不健全以及开发主体单一等问题.鉴于此,从政府作用机制、教育机制以及人才管理机制等方面对西部民族地区新农村建设中特色人力资源开发的有效途径进行探讨.     

Financial reporting consequences of natural disasters: Evidence from the impact of resource constraints at audit offices on non-affected clients

Disaster-affected clients demand significant additional effort from their audit office, and hence strain the audit office’s resources available to other non-disaster-affected clients. We consider audit offices with disaster-affected clients to be strained offices and find that, compared with clients audited by non-strained audit offices, non-disaster-affected clients audited by strained audit offices are more likely to have their financial statements restated. This result suggests the financial reporting quality of companies not directly exposed to disasters could also be negatively affected by the disasters, due to their auditors’ strained-resource issue. We further find such a negative effect is more pronounced when the degree of resource constraints is greater and when the audit office lacks client experience or industry expertise. We offer novel evidence of financial reporting consequences of natural disasters, focusing on the externality of disasters on companies not directly affected by disasters. The findings have important implications for regulators in making disaster-related policies, for auditors in managing their client portfolios, and for companies in making auditor choice decisions.
