千古先贤一圣心——胡居仁兴复白鹿洞书院浅析

以一介布衣获聘入主千年学府江西白鹿洞书院的明初理学大儒胡居仁,延名师、购书籍、量学租、陈学弊、作洞记、定学规,拳拳兴复白鹿洞书院于将废。虽因学风士习等原因导致他最终忍痛辞归,但给书院留下了宝贵的精神遗产,对整饬当时浮风士习、传播程朱理学思想有着深远的历史影响。

Goal-Setting in the Information-Generating Environment of the Universe

Problem of goal-setting is related to the fundamental principles of informationology and general, rather than specific, aproaches, which enable a more adequate appraisal of certain managerial decisions in terms of their efficiency. In article this problem is considered and from positions of informationology is formulated and on the basis of a method of full mathematical induction the Law of positive dynamics of the Universe is proved. This law establishes preference of the positive purposes in all processes happening in the Universe. Thus, the goal-setting which is carried out from positions of the described Law is the important world outlook prerequisite searching, identification and development of strategic alternatives of purposeful social innovations.

Regular Black Holes with Cosmological Constant

We present a class of regular black holes with cosmological constant A in nonlinear electrodynamics. Instead of usual singularity behind black hole horizon, all fields and curvature invariants are regular everywhere for the regular black holes. Through gauge invariant approach, the linearly dynamical stability of the regular black hole is studied. In odd-parity sector, we find that the A term does not appear in the master equations of perturbations, which shows that the regular black hole is stable under odd-parity perturbations. On the other hand, for the even-parity sector, the master equations are more complicated than the case without the cosmological constant. We obtain the sufficient conditions for stability of the regular black hole. We also investigate the thermodynamic properties of the regular black hole. and find that those thermodynamic quantities do not satisfy the differential form of first law of black hole thermodynamics. The reason for violating the first law is revealed.

Environmental Justice in the Context of Scientific Uncertainty: On the Safety of Genetically Modified Organisms

A foremost issue of our time is our response to risks,especially those arising from scientific uncertainty,such as genetically modified organisms(GMOs).In this context,we need to achieve and maintain environmental justice.This should be based on the corresponding scientific research;essentially,however,it is a kind of social construct.We must maintain a free market mechanism for the development,application,and dissemination of modern technology,including genetically modified biotech and its products.At the same time,the necessary government intervention and legal regulation of the relevant science and technology should be put in place to ensure public safety and the interests of socially disadvantaged groups.

Sample Size Determination Based on Decision Rules in Regression Analysis

Sample inference is an important way for people to carry out awareness, which is based on sampling and the subsequent sample observation. In this process, in order to ensure the purpose of the studying sample observation can be achieved, we need know the sample size in advance. Generally speaking, there are two approaches to determinate the sample size. One is power function principle, namely providing a good sampling estimation accuracy in advance, then calculate the sample size. The other are the decision rules based on Bayesian ideology. In this paper, from the perspective of statistical decision as our major decisions, we discuss the problem about the sample size determination in regression analysis. The full text of major features in this paper include： sample size determination when estimating parameters in regression model, sample size determination when doing mean-value regression prediction, and sample size determination when doing point-value regression prediction. To some extent, using decision rules to determinate sample size is better than using the power function method.
