团队生产、计量难题与企业的性质

阿尔奇安和德姆塞茨(1972)从团队生产引发的“计量难题”及其解决机制的角度来解释企业的性质。本文在概述该企业理论的概念框架的基础上,指出了该理论存在的一个缺陷,即它忽视了企业的监督者-剩余索取者和其他成员之间的利益冲突及其解决机制。

克隆人技术应用的“能做”与“应做”

本文基于哲学的维度 ,以对人的解读为切入点 ,在工具理性与价值理性的紧张中 ,分析克隆人技术应用的“能做”与“应做”,反思并祛魅工具理性 ,寻求价值理性与工具理性的统一。笔者认为 :在严格的意义上人是不可被复制的 ,克隆人技术至多只是开辟了人类繁衍、自身生命再生产的一个新途径 ;工具理性并不能从根本上解决人性与社会问题 ;试图在基因层次上确定“完人”终极标准的努力既不现实 ,又十分危险 ;克隆人技术及其应用作为一种工具理性 ,必须有其目的性价值 ;在对克隆人技术及其应用采取理性谨慎态度的同时 ,应当对探究科学未知活动给予社会宽容。

城市发展的可持续性测评初探

城市发展是否是可持续的已成为人们关注的焦点,如何测度与评价城市发展的可持续性尚无统一的认识。文章设计了一个评价城市可持续发展的框架,借助于常用统计数据,并利用应用统计学方法筛选出一个由17个指标构成的测评指标体系,运用层次分析法确定权重,并以天津市为实证案例,测度并评价其1990—1999年这10年间发展的可持续性。     

The birds and the bees: interactive graphics and problem solving in the teaching of statistics

Software which allows interactive exploration of graphical displays is widely available. In addition there now exist sophisticated authoring tools which allow more general textual and graphical material to be presented in computer-based form. The role of an authoring tool in providing a graphical interface to a strategy for solving simple statistical problems in the context of teaching is discussed. This interface allows a variety of resources to be integrated. Specific examples, including the use of dynamic graphical displays in exploring data and in communicating the meaning of a model, are proposed. These ideas are illustrated by a problem involving the identification of the sex of a herring gull.     

高兹资本主义核电技术批判理论及其当代价值

高兹是法国当代左翼生态政治思想家,他以法国发展核电技术为例,从技术、经济、生态和安全方面对资本主义使用的核电技术进行了深刻的分析和批判。他指出核电技术是"资本的圈套",符合资本主义积累逻辑,是资本主义专制的政治选择,社会生态重建的基本前提是工具转换。高兹的核电批判理论为我们审视目前的能源发展战略提供了一种新的理论视野,他对节约能源以及采用新技术发展新型能源的思考,对建设生态文明具有重要的价值。     

The Interview for Decisional Abilities (IDA): a tool to assess the decisional capacity of abused and neglected older adults

We present the Interview for Decisional Abilities (IDA), a semi-structured tool for use by adult protective services (APS) workers as part of their comprehensive assessments of clients. The IDA was created in response to a Federal mandate to standardize the procedures and competencies of APS agencies with a view to improving client assessments and facilitating cross-jurisdictional research on adult mistreatment. The proximal aim of the IDA is to guide workers in gathering information on the ability of suspected victims of adult mistreatment to make decisions about the risks they face.     

Optimal acceptance sampling for modules F and F1 of the European Measuring Instruments Directive

ABSTRACT

Acceptance sampling plans offered by ISO 2859-1 are far from optimal under the conditions for statistical verification in modules F and F1 as prescribed by Annex II of the Measuring Instruments Directive (MID) 2014/32/EU, resulting in sample sizes that are larger than necessary. An optimised single-sampling scheme is derived, both for large lots using the binomial distribution and for finite-sized lots using the exact hypergeometric distribution, resulting in smaller sample sizes that are economically more efficient while offering the full statistical protection required by the MID.     

Development of the Emergency Department Senior Abuse Identification (ED Senior AID) tool

Emergency departments (EDs) are an important health care setting for the identification of elder abuse (EA). Our objective was to develop an ED-based tool to identify EA. The initial tool included a brief cognitive assessment, questions to detect multiple domains of EA, and a physical examination. Refinement of the tool was based on input from clinical experts and nurse and patient feedback. The revised tool, which included 15 questions about EA, was then tested in an academic ED. We calculated the inter-rater reliability, sensitivity, and specificity of individual EA questions. Among ED patients age≥65 (N = 259), 17 (7%) screened positive for suspicion of EA. We identified a combination of six questions that cover the included domains of EA, demonstrated good or excellent inter-rater reliability, and had a sensitivity and specificity of 94% (95% confidence interval (CI) 71–100%) and 90% (95% CI 85–93%), respectively. These results inform a proposed screening tool for multisite validation testing.
