Serials Clutter in Online Catalogs

Abstract

Finding and deciphering serials records in online catalogs is a challenge to many library users. To understand and analyze these challenges, the author conducted searches for scientific journal titles in the online catalogs of Committee on Institutional Cooperation (CIC) libraries. The first part of the study measures the difficulty of retrieving serial records from online catalogs comparing one-word versus multiple-word titles. The second part analyzes displays for complexity by measuring the length of the complete record and the length of the holdings statements. These data show the complexity of displays and indicate the potential confusion that these displays may induce in library users.     

Improving traceability in continuous processes using flow simulations

Traceability is normally difficult to achieve in continuous processes, since there are no natural batch structures. In this article, we demonstrate flow-based simulation using process data to improve traceability in a continuous pelletising process. Using the simulation model, the engineers could test the impacts of process disturbances, identify cause and effect relations and aid control in case of process disturbances. In a field trial where the chemistry of an additive was varied during production of a special product, the simulation forecasts predicted the level of the chemical content after the plant within the errors that the engineers found acceptable.     

Fast and Stable Algorithms for Computing and Sampling From the Noncentral Hypergeometric Distribution

Although the noncentral hypergeometric distribution underlies conditional inference for 2 × 2 tables, major statistical packages lack support for this distribution. This article introduces fast and stable algorithms for computing the noncentral hypergeometric distribution and for sampling from it. The algorithms avoid the expensive and explosive combinatorial numbers by using a recursive relation. The algorithms also take advantage of the sharp concentration of the distribution around its mode to save computing time. A modified inverse method substantially reduces the number of searches in generating a random deviate. The algorithms are implemented in a Java class, Hypergeometric, available on the World Wide Web.     

Nonparametric regression with cross‐classified responses

In this article, we develop regression models with cross‐classified responses. Conditional independence structures can be explored/exploited through the selective inclusion/exclusion of terms in a certain functional ANOVA decomposition, and the estimation is done nonparametrically via the penalized likelihood method. A cohort of computational and data analytical tools are presented, which include cross‐validation for smoothing parameter selection, Kullback–Leibler projection for model selection, and Bayesian confidence intervals for odds ratios. Random effects are introduced to model possible correlations such as those found in longitudinal and clustered data. Empirical performances of the methods are explored in simulation studies of limited scales, and a real data example is presented using some eyetracking data from linguistic studies. The techniques are implemented in a suite of R functions, whose usage is briefly described in the appendix.

供应商管理库存环境下的分销网络连续近似模型

本文在现有连续近似(CA)模型的基础上,从供应商管理库存(VMI)角度出发,引入了PowerofTwo(POT)周期配送策略,构建了VMI环境下分销网络设计的CA模型。该模型的目标函数不仅包括了分销中心的建设 运营费用、运输费用,而且引进了实际中关注的存储费和订货费;该模型在确定分销网络结构的同时,也确定了各分销中心的库存策略和对其客户的配送策略。文中给出了模型的解法,利用此解法对算例进行求解,并分析了求解的结果,得出各参数变化对解的影响。     

群体决策过程组织研究述评

群体决策研究作为决策理论研究的热点和前沿在国内外方兴未艾, 尚未形成一个完整的 理论体系. 作者结合近年来在群体决策, 特别是在决策过程研究方面所做的一些工作, 以决策 过程研究为侧重点对群体决策理论研究进展进行了评述, 并通过社会选择理论和集体决策理 论的比较, 对群体决策的研究框架作了一些尝试性的探讨.     

政府主管部门与市政公用企业的博弈分析

市政公用设施具有公共性、福利性、外部性、垄断性、超余性和秩序性的经济学特征. 政府 主管部门与市政公用企业间存在着委托代理关系. 模型分析的结论证明了: 计划经济体制下市 政公用企业享受的“先用后算、多用多补”的补贴政策是导致激励弱化、成本失控、政府负担加 重的根本原因; 改革初期的“补贴包干”政策在调动企业积极性、减轻政府负担方面取得了一定 的成效, 但是这种做法仅局限于对企业的放权让利, 还存在很多缺陷; 建立现代企业制度及政 府主管部门与市政公用企业间的委托代理关系, 完善激励机制, 可以最大限度地     

基于价值管理的6 I’s 管理模式: 形成与结构

围绕价值管理,分析了基于职能管理的管理知识体系存在的问题,即忽视创新;对企业效用的存在假设越来越偏离实际,从而导致对企业组织中激励的认识偏差,甚至出现目的与手段的倒置;对信息的假设和运用有误;缺乏系统与综合,忽视整合的作用.在此基础上,提出了以价值管理为核心概念建立管理知识体系的观点,并建立了相应的6I's管理模式的框架,分析了有关要素的内涵.
