冷应激对雏鸡下丘脑-垂体-肾上腺皮质轴的影响

为探明冷应激对雏鸡下丘脑-垂体-肾上腺皮质轴的影响,对15日龄公雏鸡进行了急性(15 min、1h、3 h、6 h、12 h和24 h)与慢性(5 d1、0 d和20 d)冷应激处理(12℃±1℃),检测了雏鸡下丘脑促肾上腺皮质激素释放激素(CRH)mRNA的表达水平及血清促肾上腺皮质激素(ACTH)、醛固酮(ALD)及皮质醇(CORT)的含量。结果显示,急性应激时,随着应激时间的延长,下丘脑CRH mRNA的表达水平先略升高,随后下降,ACTH、COTR及ALD含量均呈现上升趋势,在3 h时开始下降,并处于稳定状态。慢性应激时,下丘脑CRH mRNA的表达水平呈上升趋势,ACTH含量呈缓慢下降趋势,COTR与ALD含量均呈上升趋势。结果表明,冷应激可以使下丘脑-垂体-肾上腺皮质轴的激素分泌发生改变,而且不同程度的冷应激对同一激素也会产生不同的影响。     

后现代语境下的行政管理改革与行政法

在公共选择、新公共管理、企业型政府以及治道等理论指导下,各国行政管理变革在政府职能市场化、公共服务社会化、行政权力分散化以及政府管理电子化等方面都取得了显著的成效,但改革也引发公共行政与行政法的价值冲突以及行政法非法律化、离散化与合法性危机等问题。因此,传统行政法必须进行反思,在综合考量全球化、电子化、民营化以及充分尊重人性等因素的基础上对行政组织法、行政行为法与行政救济法等进行重构。     

National Competition Policy

Economic reform in Australia certainly did not start with the Hilmer Report — it has been underway for the last 15 or so years. It began with financial deregulation and floating of the Australian dollar in the 1980s and the reduction of tariff protection, and includes more recent initiatives such as moving from the centralized wage fixing system to more flexible enterprise bargaining arrangements, restructuring of government business enterprises, developments in public administration and most recently the focus on competition policy.

自媒体时代公安机关应对公关危机的策略探讨——以辽宁大连“刘巍巍下跪维权事件”为例

近年来,随着以微博为代表的自媒体技术的兴起和发展,打破了传统新闻媒体对舆论的控制以及对信息的垄断,往往推动突发事件快速形成并使事态发展难以预测,继而引发公关危机,给公安机关应对和有效处置涉警危机带来难度。本文以大连市公安局处置2013年＂刘巍巍下跪维权＂事件为例,就公安机关应对自媒体时代突发事件引发的公关危机策略作一些探讨。     

社会契约论视角下国家限度性问题探析

从人性恶到社会契约的形成,霍布斯的《利维坦》利用社会契约论的论证逻辑,构建了一个绝对主权国家,被认为是专制主义的代表。从社会契约的原则、内容与主体间关系来看,作为国家基础的公民被国家所吞噬,国家享有对公民的绝对主导地位。然而从国家主权产生方式、社会契约的基础与目的来看,人为构建的利维坦,仍然具有自身的限度,这也是为什么霍布斯的《利维坦》同时被称为自由主义的代表作,证明了社会契约论视角的双重性。     

关于加强公安派出所建设的几个问题

Governmental liability for breach of contract

Government contracts are subject to a number of legal rulesthat have no private sector analogues and that have receivedvirtually no attention from law and economics scholar. Thisarticle explores these rules from an economic perspective, withspecial attention to the leading modern case on the subject,United States v. Winstar. The analysis emphasizes a number ofdifferences between governmental and private actors that haveimportant implications for the wisdom of applying conventionalbreach of contract remedies to the government. These differencesafford plausible efficiency justifications, in our view, formany of the most important doctrines governing government contracts.Some of these doctrines help to impede the use of long-termcontracts to insulate inefficient rent-seeking arrangementsagainst subsequent attack, some seem to prevent the governmentfrom inefficiently contracting away its ability to respond tonew information, and others seem to work a sensible allocationbetween the government and private contractors of the risk thatgovernment may change its policies. Not all doctrines and decisionscan be justified in this fashion, however, and we do not meanto claim that the existing body of law is in any sense optimal.Indeed, the Winstar decision itself seems quite mistaken froman economic standpoint. The considerations that we develop haveimplications for a number of related legal issues. Not all ofthese implications are developed here, but we do consider modernlitigation under the Contract Clause of the U.S. Constitutionas well as the recent academic debate about the wisdom of retroactivetaxation.
