现代高校教师的劳动特性与人性化管理问题探析

"人性化管理"是由现代行为科学演变出来的一种新的管理概念,随着知识时代的来临,人作为知识、智慧的主体变得越来越重要,而高校是人才聚集之地,如何合理开发人的内在潜能,已成为新形势下高校人事管理部门研究的重要课题。本文分析了高校教师劳动特性并对高校教师人性化管理的问题进行了探析,对人事制度改革过程中的教师管理问题具有一定的指导意义。     

怀特海的大学教育思想述评

怀特海认为大学存在的理由在于,它是青年和老年人之间进行知识和生命沟通的桥梁;大学要培养学生的智慧、想像力和创造力;大学的教学应该与学生的生活结合起来,让学生获得活的知识;大学的管理不同于商业或其他部门,应该尊重大学和大学教师的独立性和自由。

一种海底应答器绝对位置的精确校准方法

应答器越来越多地应用于各种水下作业,而其绝对位置的校准是工作的前提。在深海下由于声速的不均匀性,声线会发生弯曲。海底应答器绝对位置的校准需要进行声线弯曲修正。给出了一种深海条件下含声线弯曲修正的海底应答器绝对位置精确校准的方法。深海试验结果验证了该算法的有效性以及进行声线修正的必要性。

Subspace dynamic‐simplex linear interpolation search for mixed‐integer black‐box optimization problems

Design and management of complex systems with both integer and continuous decision variables can be guided using mixed‐integer optimization models and analysis. We propose a new mixed‐integer black‐box optimization (MIBO) method, subspace dynamic‐simplex linear interpolation search (SD‐SLIS), for decision making problems in which system performance can only be evaluated with a computer black‐box model. Through a sequence of gradient‐type local searches in subspaces of solution space, SD‐SLIS is particularly efficient for such MIBO problems with scaling issues. We discuss the convergence conditions and properties of SD‐SLIS algorithms for a class of MIBO problems. Under mild conditions, SD‐SLIS is proved to converge to a stationary solution asymptotically. We apply SD‐SLIS to six example problems including two MIBO problems associated with petroleum field development projects. The algorithm performance of SD‐SLIS is compared with that of a state‐of‐the‐art direct‐search method, NOMAD, and that of a full space simplex interpolation search, Full‐SLIS. The numerical results suggest that SD‐SLIS solves the example problems efficiently and outperforms the compared methods for most of the example cases. © 2017 Wiley Periodicals, Inc.

Optimal maintenance policies for a safety‐critical system and its deteriorating sensor

We consider the integrated problem of optimally maintaining an imperfect, deteriorating sensor and the safety‐critical system it monitors. The sensor's costless observations of the binary state of the system become less informative over time. A costly full inspection may be conducted to perfectly discern the state of the system, after which the system is replaced if it is in the out‐of‐control state. In addition, a full inspection provides the opportunity to replace the sensor. We formulate the problem of adaptively scheduling full inspections and sensor replacements using a partially observable Markov decision process (POMDP) model. The objective is to minimize the total expected discounted costs associated with system operation, full inspection, system replacement, and sensor replacement. We show that the optimal policy has a threshold structure and demonstrate the value of coordinating system and sensor maintenance via numerical examples. © 2017 Wiley Periodicals, Inc.
