Integration Deficits of IT Controlling

The paper is based on the thesis that IT controlling suffers from two integration deficits with regard to its methods base: On the one hand, this is a lack of synchronization between research on IT controlling methods and developments in practice; on the other hand, a lack of integration of IT controlling methods with methods of business and information systems engineering (BISE). Based on this assumption, the paper investigates historical developments in IT controlling research and practice to derive theses about the present state of method integration. The analysis finds indications for further potential for method integration and identifies these potentials. Requirements towards method integration are derived from an analysis of the identified integration potentials and two examples illustrate how to realize further integration. Accepted after two revisions by the editors of the special focus.

基于SSM的福建省区域制造业结构比较研究

利用偏离-份额分析法分析了福建省9个设区市制造业的结构和地域分工特征,研究发现福建省东部地区制造业竞争力比西部地区强、知识密集型产业比重高,同时发现福州市制造业地位正在下降,最后结合实际针对福建省制造业结构和地域分工的特征提出优化整合对策,以优化配置制造业资源,提高福建省区域制造业竞争力。     

教师如何有效实施螺旋式项目教学法

在计算机专业的一些实践性很强的技能型课程中,采用新的螺旋式项目教学法,根据课程应用性的特点,以及职业能力的需求,在宏观的课程上的拓展,微观课堂上递进驱动教学法将理论教学与实践教学有机结合,实践教学效果很明显。但是新的教学方法对教师的工作任务有了新得标准,如何处理知识点的衔接,实现螺旋式上升势态,教学过程中如何把握知识点的内在联系,加强知识的层次性,最终实现知识点层层梯进,逐步深入。     

Toward a more practical approach to evaluating programs: The Multi‐Objective Realization approach

Emerging trends indicate that programs are being used to deliver benefits that may not be fully harnessed from single sets of uncoordinated projects. To support this movement, it is essential to have suitable measurement frameworks to assess the contribution of these activities and supply decision makers with valuable data on whether their objectives are being realized. This paper introduces the Multi‐Objective Realization Method (MORE) to help measure the strategic contributions of programs. The main principles of MORE underline the importance of a formal strategy to elicit and develop program objectives and to frame those objectives within defined measurement dimensions.     

Labour adjustment costs: Estimation of a dynamic discrete choice model using panel data for Greek manufacturing firms

In this paper we estimate a dynamic structural model of employment at firm level. Our dataset consists of a balanced panel of 2790 Greek manufacturing firms. The empirical evidence of this dataset stresses three important stylized facts: (a) there are periods in which firms decide not to change their labour input, (b) there are periods of large employment changes (lumpy nature of labour adjustment) and (c) the commonality is employment spikes to be followed by smooth and low employment growth periods. Following Cooper and Haltiwanger [Cooper, R.W. and Haltiwanger, J. “On the Nature of Capital Adjustment Costs”, Review of Economic Studies, 2006; 73(3); 611–633], we consider a dynamic discrete choice model of a general specification of adjustment costs including convex, non-convex and “disruption of production” components. We use a method of simulated moments procedure to estimate the structural parameters. Our results indicate considerable fixed costs in the Greek employment adjustment.     

一种新的超市门店需求预测方法与库存管理模型

探讨了VMI模式下如何确定连锁超市门店的订货点的问题。利用专家判定法改进了基于历史数据的零售商需求预测模型，并在此需求预测模型基础上提出一种具有时间和数量柔性的自动补货策略模型。最后通过实倒分析表明，研究结果有助于帮助企业在快速响应市场需求的同时。降低企业的成本，提高企业的竞争力。此模型将在某连锁百货的订货系统中得到应用。     

快速全站仪三角高程测量方法及应用

传统三角高程测量由于受仪器高和棱镜高量取误差的影响，精度较低。文章介绍了两种较传统三角高程测量更为简易且高精度的方法，分别是中间法和设定参数法。这两种方法无需量取仪器高和棱镜高，减少了三角高程测量的误差来源，提高了观测的精度。     

基于六西格玛管理法的我国银行流程再造研究

基于六西格玛管理法的银行流程再造(PRSS),是以银行业务流程为切入点,引入六西格玛管理法的思想、步骤、目标、技术方法来规范、量化银行流程再造,并以其作为理论指导路径和实施框架,从而不断提高顾客满意度与绩效,使银行获得持续的动态竞争优势。它是一项复杂而持久的系统工程,需要对整个银行体系传统的经营理念和经营模式进行全面而深刻的变革。

资本永续盘存法及其国内应用

资本存量数据是宏观经济运行政策研究的重要决定因素。资本存量核算比较复杂，在理论与技术两个层面都存在诸多问题难以厘清。我国资本统计十分薄弱，数据可得性成为资本存量估算的严重制约。在我国经济增长研究中，如何准确估算资本存量一直是困扰研究者的难题。学术界需要使用这方面数据，又促使很多学者基于各自的研究目的对我国资本存量进行估算。这些研究分别利用不同的假设和处理方法，这使我国资本存量数据出现了差异很大的众多版本。本文在对资本存量估算方法进行梳理之后，对我国资本估算现有研究进行了回顾和评论。
