高原卫士奉献精神的哲学反思

立足推进人类社会精神文明建设和加强部队思想建设,把高原卫士作为认识对象,运用马克思认识论和实践观,分析高原卫士在特殊环境里所具备的那种高尚品格和生命价值观。在阐述高原卫士奉献精神本质、内涵,及其实践效果的基础上,追问奉献精神产生的双重根源,指出:高原卫士可贵之处是奉献,人类文明需要可贵的奉献精神。     

秘密监听原则探析

秘密监听对公民宪法所保障的权利和自由产生了威胁,但是对侦查日益智能化的犯罪又是不可或缺的证据收集方式。从适应刑事庭审方式对证据要求的角度对秘密监听加以规范,使其以最小化的侵犯公民权利、自由的方式,达到证据收集效率的最优化,使以秘密监听收集方式获得的证据不致因违法而被排除在法庭之外,就必须从理论上解决秘密监听的法理依据及其密切相关的强迫自证其罪与拒绝证言权等问题,并使其能够最终成为定案的依据。     

消防责任事故罪构成要件探讨

消防责任事故罪包括客体、客观要件、主体、主观要件等若干构成要件,其客体为“国家的消防监督制度”,其客观要件是“经消防监督机构通知采取改正措施而拒绝执行”,其主体为特殊主体“直接责任人员”,其主观要件应限于过于轻信的过失。

Stochastic scheduling subject to machine breakdowns: The preemptive‐repeat model with discounted reward and other criteria

We consider the problem of scheduling a set of jobs on a single machine subject to random breakdowns. We focus on the preemptive‐repeat model, which addresses the situation where, if a machine breaks down during the processing of a job, the work done on the job prior to the breakdown is lost and the job will have to be started from the beginning again when the machine resumes its work. We allow that (i) the uptimes and downtimes of the machine follow general probability distributions, (ii) the breakdown process of the machine depends upon the job being processed, (iii) the processing times of the jobs are random variables following arbitrary distributions, and (iv) after a breakdown, the processing time of a job may either remain a same but unknown amount, or be resampled according to its probability distribution. We first derive the optimal policy for a class of problems under the criterion to maximize the expected discounted reward earned from completing all jobs. The result is then applied to further obtain the optimal policies for other due date‐related criteria. We also discuss a method to compute the moments and probability distributions of job completion times by using their Laplace transforms, which can convert a general stochastic scheduling problem to its deterministic equivalent. The weighted squared flowtime problem and the maintenance checkup and repair problem are analyzed as applications. © 2004 Wiley Periodicals, Inc. Naval Research Logistics, 2004     

Exact likelihood inference for the exponential distribution under generalized Type‐I and Type‐II hybrid censoring

Chen and Bhattacharyya [Exact confidence bounds for an exponential parameter under hybrid censoring, Commun Statist Theory Methods 17 (1988), 1857–1870] considered a hybrid censoring scheme and obtained the exact distribution of the maximum likelihood estimator of the mean of an exponential distribution along with an exact lower confidence bound. Childs et al. [Exact likelihood inference based on Type‐I and Type‐II hybrid censored samples from the exponential distribution, Ann Inst Statist Math 55 (2003), 319–330] recently derived an alternative simpler expression for the distribution of the MLE. These authors also proposed a new hybrid censoring scheme and derived similar results for the exponential model. In this paper, we propose two generalized hybrid censoring schemes which have some advantages over the hybrid censoring schemes already discussed in the literature. We then derive the exact distribution of the maximum likelihood estimator as well as exact confidence intervals for the mean of the exponential distribution under these generalized hybrid censoring schemes. © 2004 Wiley Periodicals, Inc.
