Differences between workstations and keypad group support systems: Implications for keypad GSS facilitators

Organizations are successfully using group support systems (GSS) to improve efficiency, effectiveness, and satisfaction in organizational meetings. Meeting success relies on making an appropriate match between group, taks, and technology. This responsibility often falls to the meeting facilitator. This article draws upon GSS and facilitation literature to develop a framework for the discussion of effective facilitation in workstation and keypad meeting environments. The article identifies differences between the systems and how they impact upon the behavior of the meeting facilitators and their choice of technology. Compensatory actions are proposed for keypad facilitators to address the lack of key workstation features. Keypad strengths are also identified to show the opportunities available to facilitators to maximize the benefits of using these GSS. Further, it is proposed that different types of GSS are not mutually exclusive and should be seen as complementary components of a suite of GSS tools designed to support organizational goals.     

Implications of Negotiation Theory for Research and Development of Negotiation Support Systems

This paper summarizes a parametric theory of negotiation as a basis forshedding light on negotiation support system possibilities. Previously, thetheory has been used to analyze prior research accomplishments in the area ofnegotiation support systems. Here, we discuss implications of the theory thatare relevant for future research and development of negotiation supportsystems. The implications are concerned with three topics: a high-levelgeneric characterization of these systems, an identification of theirpossible support functions, and a taxonomy for classifying suchsystems.     

条带充填开采支巷快速掘进支护技术

以山西三元煤矿1#充填工作面的具体工程地质特征及生产技术条件为背景,在保证巷道安全稳定的前提下,提出一种能够科学匹配沿空掘巷围岩现场实际变形破坏的新型支护理念与关键技术。结果表明：巷道掘出后围岩塑性区主要分布于巷道两帮及顶底板,巷道两帮的破坏主要是剪切破坏, 顶板处几乎没有塑性区的分布,底板塑性区分布较广泛,导致破碎岩层发生比较强烈的扩容变形,从而进一步加剧了帮部围岩和巷道肩窝的破坏变形。根据锚杆锚索长度计算原理图,并结合1#充填工作面顺槽巷道掘出后扰动应力分布曲线图,最终确定锚杆锚索参数。     

基于支持向量机的网贷借款人违约风险评估

随着互联网金融的发展,P2P网贷平台规模急速扩大,网贷平台的跑路潮现象及借款人违约问题等也随之出现,这极大制约着网贷平台的健康发展。利用爬虫技术获取借款人信息,选取17个核心变量为解释变量、项目状态为目标变量,并通过交叉验证确定支持向量机模型的最优参数,建立最佳网贷借款人违约风险评估模型。实验结果表明,模型的稳定性和泛化能力较好,研究结果可为网贷平台风险预警和风险防控等方面提供决策支持,有助于促进网贷平台健康发展。     

产业政策对总经理变更的影响

基于2000—2020年沪深A股上市公司数据,考察产业政策是否影响总经理变更概率,以及政策特征和企业特征对两者关系的影响。实证结果表明：获得产业政策支持的企业更可能变更总经理;产业政策支持的力度越大,总经理变更的可能性越大,表现为重点支持产业政策比一般鼓励产业政策、中央和地方配套的产业政策比独立实施的产业政策对企业总经理更替的影响更大;动态分析表明,产业政策对总经理变更的影响主要出现在政策颁布实施的第1、第2和第5年;异质性分析表明,处于垄断性行业、规模更大、总经理持股比例更高的企业,产业政策对总经理变更的影响会削弱。     

承诺补贴--对高新技术出口产业的一种市场进入扶持政策

发展中国家的出口产品结构现状表明其在一些高新技术出口产业上处于劣势：而从长期的动态的角度上看,鼓励这些产业的发展又是发展中国家优化本国出口产品结构的必由之路,通过模型分析我们发现,在一定条件下,发展中国家政府对本国企业承诺补贴使其净利润非负的市场进入扶持政策能达到预期的效果而补贴却无需兑现。当然此扶持政策有其自身固有的弊端．应慎重合作,同时应将最终眼光投向根本上提高本国高新技术出口产业的竞争力上。     

韩国德国产业政策比较及对我国的启示

韩国和德国经济的全面发展,在很大的程度上依赖于其有效的产业政策。进入20世纪90年代末期,德国企业继续保持着蓬蓬勃勃的向上势头,韩国经济却面临东南亚的金融危机中,出现了动荡不安的局面,这也是由于他们采取的产业政策不同所致。金融危机以后,韩国开始审视并重新制定完善其产业政策。至今经济得到较快地恢复和发展。中国应从中得到深刻的启示。

文章指出 ,社会养老不能取代家庭养老。在社会转型时期 ,中国家庭养老保障制度遇到诸多困难并引发一系列家庭矛盾。文章提出 ,必须合理界定赡养人的范围、明确家庭养老的内容、成立专门的家庭养老管理机构、严惩不履行赡养义务者。     

Group Decision Support Using Fuzzy Cognitive Maps for Causal Reasoning

Cognitive maps have been used for analysing and aiding decision-making by investigating causal links among relevant domain concepts. A fuzzy cognitive map (FCM) is an extension of a cognitive map with the additional capability of representing feedback through weighted causal links. FCMs can be used as tools for both static as well as dynamic analysis of scenarios evolving with time. An FCM represents an expert's domain knowledge in a form that lends itself to relatively easy integration into a collective knowledge base for a group involved in a decision process. The resulting group FCM has the potential to serve as a useful tool in a group decision support environment. An appropriate methodology for the development and analysis of group FCMs is required. A framework for such a methodology consisting of the development and application phases is presented.     

广西财政支农支出对农民收入影响的协整分析

文章采用协整分析方法对1982--2007年广西财政支农支出对农民收入的影响进行了实证分析。研究表明,广西财政支农与农民收入之间存在长期均衡关系,加大财政支农力度能有效促进农民增收。广西财政支农支出结构中对农民增收效应高低的次序为：支援农村生产支出最高,农业基本建设支出次之,支援不发达地区支出居第三,农林水利气象等部门的事业费最差。
