维特根斯坦界限主体的三重意蕴——维特根斯坦的主体思想探析

界限主体是维特根斯坦在其逻辑哲学中提出的一种特殊的主体形式,是主体界限化的结果。它区别于意识主体、身体主体、心灵主体等主体形式,是主体的极限情形。界限主体具有逻辑、语言和意志三重意蕴。界限主体的三重性,使形而上学主体与逻辑主体、语言主体、意志主体在某种程度上得到了合理的统一。界限主体的确立,既解决了主体的“体”带来的一系列问题,同时又为主体在逻辑语言的层面上找到了一种合理的存在形式。     

论官僚政治与商业资本的互动逻辑——双重纬度:下限和上限、矛盾与异化

唯物史观视角下,官僚政治不单纯是一个政治范畴,而是以专制政治权力为核心建构的政治形态层面、制度层面、过程层面、文化层面、技术层面的有机统一体。“下限和上限”、“矛盾与异化”构成政治哲学的双重纬度并有效解析商业资本与官僚政治两者间的互动逻辑和矛盾运动。     

略论限度观

限度对于人们生存和发展具有重要的指导意义。为更好地适应时代发展要求，人们应该确立科学合理的限度观：必须恪守“最低限度”，应该追求“最大限度”，务必防止“无意过度”，可以倡导“超越限度”。确立科学合理限度观体现了科学发展的精神，有利于和谐社会的构建，有益于社会主客体的发展。人们要在实践和感悟中去寻求、把握和发展限度。科学合理限度观的确立，必须坚持求真务实、持续发展和公正发展等实践原则。     

Single sampling plans indexed by point op control and inflection point

Three tables for selection of single sampling plans with any one of the following combinations of entry parameters are givens.

1) the indifference quality level and the average outgoing quality limit.

2) the indifference quality level with relative slope of the OC curve at that quality leve land.

3) the quality level corresponding to the inflection point with relative slope of the OC curve at that quality level.

A table enabling the transition from one set of parameters to match the OC curve of other similar sets is also given.     

Estimation of Correlation for Continuous Semimartingales

Abstract. In this study we are concerned with inference on the correlation parameter ρ of two Brownian motions, when only high‐frequency observations from two one‐dimensional continuous Itô semimartingales, driven by these particular Brownian motions, are available. Estimators for ρ are constructed in two situations: either when both components are observed (at the same time), or when only one component is observed and the other one represents its volatility process and thus has to be estimated from the data as well. In the first case it is shown that our estimator has the same asymptotic behaviour as the standard one for i.i.d. normal observations, whereas a feasible estimator can still be defined in the second framework, but with a slower rate of convergence.     

On LSE in regression model for long-range dependent random fields on spheres

We study the asymptotic behaviour of least squares estimators (LSE) in regression models for long-range dependent random fields observed on spheres. The LSE can be given as a weighted functional of long-range dependent random fields. It is known that in this scenario the limits can be non-Gaussian. We derive the limit distribution and the corresponding rate of convergence for the estimators. The results were obtained under rather general assumptions on the random fields. Simulation studies were conducted to support theoretical findings.     

Critical Effects and Exposure Limits

The use of critical effects in the determination of occupational exposure limits (OELs) in Sweden is subjected to a statistical study. Many of the present OELs are high in relation to known noeffect levels and effect levels, and the degree of protection has a surprisingly weak correlation with the seriousness of the adverse effect. Several proposals for improved procedures are put forward. One of these is to supplement the concept of critical effects with that of dominant effects. A dominant effect of a substance is a health effect that is at some concentration the most serious health effect.     

Limits of quantitation for laboratory assays

Summary.  A common problem with laboratory assays is that a measurement of a substance in a test sample becomes relatively imprecise as the concentration decreases. A standard solution is to establish lower limits for reliable measurement. A quantitation limit is a level above which a measurement has sufficient precision to be reliably reported. The paper proposes a new approach to defining the limit of quantitation for the case where a linear calibration curve is used to estimate actual concentrations from measured values. The approach is based on the relative precision of the estimated concentration, using the delta method to approximate the precision. A graphical display is proposed for the assessment of estimated concentrations, as well as the overall reliability of the calibration curve. Our research is motivated by a clinical inhalation experiment. Comparisons are made between the approach proposed and two standard methods, using both real and simulated data.
