Decision Analysis for Utilizing Hazardous Waste Site Assessments in Real Estate Acquisition

When a buyer needs to purchase commercial or industrial property, the decision of what real estate to purchase should be based on an assessment of the total costs of acquisition. In addition to the direct purchase cost, other possible costs include hazardous waste site assessment studies and clean up costs if the purchased site proves to be contaminated. This paper presents a decision analysis model for determining when and which type of hazardous waste assessment tests should be conducted and how the test output affects the choice of site. The model assumes there are two types of hazardous waste assessment, an historical use review (phase 1 test)and soil and water sampling (phase 2 test). Model inputs include the cost, sensitivity and specificity for each type of test, a site's purchase price, and a priori probability of contamination, along with the clean-up cost for a contaminated site. The analysis uses the results of a data survey of 17 environmental engineering firms in setting values on the model input requirements. The paper also reports on sensitivity analysis with the model for the purpose of providing decision-makers with explicit protocols for test utilization.     

An evaluation of the American Community Survey: results from the Oregon test site

The American Community Survey (ACS) is a Census Bureau product designed to provide accurate and timely demographic and economic indicators on an annual basis for both large and small geographic areas within the United States. Operational plans for Census 2010 call for ACS to replace the decennial census long form (Census LF), pending the results of evaluation studies. This plan represents a major change in that variables that traditionally have been collected on a “snapshot” basis once every 10 years would be collected on a “rolling” annual basis. Using a loss function analysis and other tools, this paper reports preliminary findings from a comparison of ACS and Census 2000 results in Multnomah County, Oregon, one of five national “local expert” test sites set up to compare ACS data collected at the time of Census 2000. The preliminary findings suggest that there are notable differences between some of the corresponding variables found in the ACS and Census LF that require more detailed examination. For example, the loss function analysis reveals notable differences for race and disability variables. In other comparisons of corresponding variables between ACS and Census 2000, differences are found within each of the four major areas of interest: (1) demographic characteristics, (2) social characteristics, (3) economic characteristics, and (4) housing characteristics, with housing characteristics showing the least similarity overall. These results also suggest that more detailed examinations are needed to understand differences between corresponding variables collected by ACS and the Census LF.

大辛庄遗址的考古发现与研究

大辛庄遗址是一处以商文化为主要内涵的古代遗址。遗址最初由当地农民发现于1935年,而最早把这一发现公诸于学术界的,则是英国人林仰山(F.S.Drake)教授。五十年代的两次勘探,探明了大辛庄遗址的面积,初步确认遗址的主要堆积和年代。1984年的发掘,建立起鲁北地区商文化陶器的发展序列。2003年春季的发掘,因发现商代甲骨文而引起海内外学术界的广泛重视。这是在商都殷墟以外首次于原生地层中发现甲骨卜辞,被誉为甲骨学史上具有界标意义的重大考古发现。这次发掘所发现的青铜器族徽,不见于以往著录,是研究商代历史和社会的重要资料。随着研究的深入,大辛庄遗址将愈益显示出其重要的学术地位。

Blinded sample size re‐estimation in crossover bioequivalence trials

In drug development, bioequivalence studies are used to indirectly demonstrate clinical equivalence of a test formulation and a reference formulation of a specific drug by establishing their equivalence in bioavailability. These studies are typically run as crossover studies. In the planning phase of such trials, investigators and sponsors are often faced with a high variability in the coefficients of variation of the typical pharmacokinetic endpoints such as the area under the concentration curve or the maximum plasma concentration. Adaptive designs have recently been considered to deal with this uncertainty by adjusting the sample size based on the accumulating data. Because regulators generally favor sample size re‐estimation procedures that maintain the blinding of the treatment allocations throughout the trial, we propose in this paper a blinded sample size re‐estimation strategy and investigate its error rates. We show that the procedure, although blinded, can lead to some inflation of the type I error rate. In the context of an example, we demonstrate how this inflation of the significance level can be adjusted for to achieve control of the type I error rate at a pre‐specified level. Furthermore, some refinements of the re‐estimation procedure are proposed to improve the power properties, in particular in scenarios with small sample sizes.

Lead factory operationalisation and challenges

Abstract

This paper deepens the understanding of the lead factory concept by examining how the lead factory role is operationalised and what challenges are associated with it. The research is based on an explorative case study of eight Swedish lead factories in the manufacturing industry. The empirical findings suggest that the understanding of the lead factory concept should be extended as it is not restricted to one type of set-up. The findings show a spectrum ranging from an entire manufacturing plant, parts of a plant, to a virtual plant considered to be the lead factory. The research also shows a broad range of challenges experienced by lead factories. Several of these are related to and originate from unclear role, responsibility and mandate of the lead factory. The lack of dedicated resources for lead factory activities, specifically long-term development and difficulties in measuring the benefits of the role, were other challenges faced.

“批判佛教”的批判哲学

吕凯文指出,袴谷宪昭凸显"批判哲学"对抗"场所哲学"的意义,旨在遏止"西欧思想(场所哲学)流入日本",免使佛教"非佛教化"而不再具有公开的、客观的知识批判以及具有公义的社会实践能力。吴可为提出,松本史朗强调如来藏或本觉思想作为东亚大乘佛教的主流和基础,是一种非批判性的"界论"、一元论的基体主义、彻底的"我论"。其实,如来藏佛教不但不缺乏批判性,甚至可能提供一切佛教中最全面和最深刻的批判力;松本的解读基本上依照西方哲学的框架、角度和方法,隐含着一种理性主义和西方中心论的视角。刘宇光认为,"批判佛教"首度尝试把当代日本佛教中各种抵抗现代实体论的零碎的异议声音整合为一体,一方面在传统教义的论辩中凸现出代脉络中的新向度,另一方面又能把对现代实体的批判定为教义的必然要求;但是,他们存在着本质主义的倾向、论证与修辞上对各种"本土思想"的排他态度以及在方法论上自相矛盾等诸多问题。周贵华认为,"批判佛教"将佛教精神定为批判性,相当程度上是正确的,但佛教作为在漫长历史中由众多教派形成的复杂思想传统,不可能只有一种单面化的衡量与裁定,所以,"批判佛教"对佛教思想特质的归纳颇为片面;从历史与文献的角度看,其不少论断相当武断;其将日本社会的不平等状况、种族问题以及日本文化的弊端直接归咎于本觉思想,在逻辑上亦不可靠。
