电子手写签名认证算法的研究

文章提出了在微机Windows环境中的一种联机电子手写签名认证算法。该算法在强调签名的形状和签名压力的动态特征上都具有相似性,并采用了基于特征函数的点—点手写签名匹配映射方法,先将联机输入的电子手写签名切分为笔段,以笔段作为签名的特征区,对两个待比较的签名相应笔段中的点,经由点—点的映射算法得到最后的匹配映射结果。

信息需求与IT投资的商业价值：组织资本视角的审视

我国企业对信息技术（简称IT）的投资巨大，已成为世界各大IT厂商的主要市场之一，但国内学术界和企业对IT投资对企业绩效的作用机理研究甚少。本文认为，IT投资是为了满足企业的信息需求，而企业的信息需求充分体现在组织资本的信息本质中，因此，IT投资的商业价值在于它促进了组织资本的形成和积累，并通过组织资本对组织的价值创造和价值增长产生有力的促进作用。本文力图帮助企业理解IT投资对企业绩效的作用机理，从而能够采取合理的IT投资策略以最大化IT投资的商业价值。     

On the Natural and Economic Difficulties to Fulfilling the Human Right to Water Within a Neoclassical Economics Framework

We present a neoclassical economic model of the human right to water using a nonrenewable resource model inclusive of a backstop technology. The right is interpreted as a minimum consumption requirement the government is obligated to fulfill in the event that any one household cannot do so independently. Differing by income levels, households maximize utility by purchasing a composite consumption good and water from two distinct, government-owned sources. Facing physical and financial constraints, the government uses fiscal policy to address potential human rights violations. Reducing the analysis to two periods, we develop a novel approach to compare total welfare levels from a joint human rights and neoclassical economics perspective. We define a human rights welfare standard and discuss cases in which traditional social welfare measures would exceed, violate, or meet this standard. We thus offer a unique way to merge economic analysis with human rights research.     

Validation of an economic model of paliperidone palmitate for chronic schizophrenia

Abstract

Objective:

Model validation is important, but seldom applied in chronic schizophrenia. Validation consists of verifying the model itself for face validity (i.e., structure and inputs), cross-validation with other models assessing the same issue, and comparison with real-life outcomes. The primary purpose was to cross-validate a recent pharmacoeconomic model comparing long-acting injectable (LAI) antipsychotics for treating chronic schizophrenia in Sweden. The secondary purpose was to provide external validation.

Methods:

The model of interest was a decision tree analysis with a 1-year time horizon with costs in 2011 Swedish kroner. Drugs analyzed included paliperidone palmitate (PP-LAI), olanzapine pamoate (OLZ-LAI), risperidone (RIS-LAI), haloperidol (HAL-LAI), and oral olanzapine (oral-OLZ). Embase and Medline were searched from 1990–2012 for models examining LAIs. Articles were retrieved, with data extracted for all drugs compared including: expected costs, rates of hospitalization, proportion of time not in relapse, and associated QALYs. Outcomes from the model of interest were compared with those from other articles; costs were projected to 2012 using the consumer price index.

Results:

Twenty-six studies were used for validation; 14 of them provided evidence for cross-validation, 13 for external validation, and four for cost. In cross-validation, cost estimates varied ?1.8% (range: ?12.4–20.1%), hospitalizations 5.2% (?12.1–3.1%), stable disease 2.5% (?5.6–1.5%), QALYs 9.0% (4.3% after removing outliers). All estimates of clinical outcomes were within 15%. In external validation, hospitalization rates varied by 6.3% (?0.7–11.3%). The research was limited by data availability and validity of the original results.

Conclusion:

Other models validated the outputs of our model very well.

KTV火灾模拟及安全疏散研究

KTV是人员密集场所,一旦发生火灾便容易造成人员伤亡和财产损失。因此,对KTV火灾进行模拟,研究人员的安全疏散显得尤为重要。文章以某一KTV为例,运用CFAST软件进行火灾模拟与分析,将得出的上下层烟气温度、烟气层高度等参数与人体能承受的相对指标作比较,以此来判定在疏散设计时间内人员能否安全撤离。由此得出的结论可为KTV的人员安全疏散设计提供理论依据。
