An extended exponentiated-G-negative binomial family with threshold effect

In this paper, we formulate a very flexible family of models which unifies most recent lifetime distributions. The main idea is to obtain a cumulative distribution function to transform the baseline distribution with an activation mechanism characterized by a latent threshold variable. The new family has a strong biological interpretation from the competitive risks point of view and the Box–Cox transformation provides an elegant manner to interpret the effect on the baseline distribution to obtain this alternative model. Several structural properties of the new model are investigated. A Bayesian analysis using Markov Chain Monte Carlo procedure is developed to illustrate with a real data the usefulness of the proposed family.     

企业价值网络文献综述及未来研究方向展望

企业价值网络的形成主要从价值链理论寻求理论依据,模块化理论是企业价值网络运营机理的重要阐释工具。企业价值网络的竞争优势问题是当前价值网络研究领域的核心问题,主要围绕竞争优势的表现、竞争优势的阐释和竞争优势的演化三方面展开。企业价值网络的治理问题、网络文化管理问题以及有针对性的相关产业、企业个案的研究也正在进行当中。企业价值网络的未来研究方向主要在于构筑价值网络战略理论模型,整合战略网络的现有研究成果、整合市场营销相关理论成果以及定量研究的展开。     

中国地区文化产业竞争力的实证研究

本文提出从文化产业实力、产业效益、产业结构和产业环境等四个方面考察区域文化产业的竞争力,构建了定量化的评价模型。应用该模型对中国主要地区的文化产业竞争力进行了综合评价,找出各区域的差异并进行了层级分类。根据实证分析结果,分别针对不同层级的区域上以及我国整体上提升文化产业的竞争力提出建议。     

从价值链管理到知识价值链管理——企业获取竞争优势的必然选择

基于波特价值链设计出由知识管理主要活动（包括知识审计、知识获取、知识创造、知识吸收、知识保护与知识应用）与辅助活动（包括知识领导、知识协调、知识控制、知识组织、知识测评）组成的知识价值链,并对知识价值链管理与价值链管理从价值活动划分标准、价值活动种类与范围、竞争优势来源、核心管理方法、信息技术与知识的利用程度、价值活动的协调机制、价值链扩展性等方面进行了比较,建议企业采取诸如执行系统化知识审计、建立战略联盟、开展知识协调、采用先进信息技术、加强组织学习、建立知识型组织等策略来实施知识价值链管理。     

Uncertainty in competitive bidding – a framework for product–service systems

Owing to servitisation, manufacturing companies are increasingly required to compete through the provision of services around their products. The contracts for these services are often allocated through competitive bidding where the potential suppliers submit a price bid to the customer. The pricing decision is influenced by various uncertainties. This article proposes a conceptual framework depicting these influencing uncertainties on the bidding strategy. This framework is based on three empirical studies with industry investigating different viewpoints on the decision-making process. The intention is to support the pricing decision when competitively bidding for a service contract. The framework can be applied to specific competitive bidding situations to identify the influencing uncertainties, model them and depict their influences on the pricing decision.     

基于网络效应的竞争性产品微观扩散研究

竞争性产品扩散是成熟市场的重要表现,网络效应的存在不仅改变了传统的扩散模式, 而且对个体采纳行为有重要影响． 但是以往研究竞争性产品扩散侧重于宏观层面的扩散速度和扩散效果,忽略了微观层面个体的个性以及社会交互等特点对产品扩散的影响,因此需要基于网络效应从个体微观层面研究竞争性产品扩散的特点． 首先构建了基于个体间交往关系的直接网络效应函数和基于多种互补产品协同作用下的间接网络效应函数,然后,个体将计算自己当前时刻的收益以及下一时刻的预期收益,并根据预期社会化效益满意决策机制确定下一时刻的产品选择． 通过仿真对扩散系统进行研究,结果表明: 直接网络效应和间接网络效应对竞争性产品扩散具有阶段性影响; 在小世界网络的社会交往结构中竞争性产品扩散效果最好; 个体人数分布、偏好、对环境的判断都对竞争性产品扩散有重要影响．     

Using Public Feedback and Competitive Rewards to Increase the Safe Driving of Pizza Deliverers

Abstract

This study investigated the effects of a safe driving competition facilitated by publicly-posted individual feedback. The turn-signal use, safety-belt use, and complete intersection stopping of 82 pizza deliverers were observed at two experimental and three control stores, as well as among the civilian population. After baseline observations, pizza deliverers received posted weekly individual feedback on their turn-signal use (at Store A) or complete intersection stops (at Store B). The deliverers' safe driving scores were posted individually on a vertical scale along with their names. Each week the deliverer with the highest average performance was rewarded with a free vehicle-maintenance coupon. Turn-signal use among drivers at Store A (n= 24) increased 22 percentage points from baseline to the intervention phase which was maintained into the withdrawal phase. Complete intersection stopping among drivers at Store B (n= 21) increased 17 percentage points from baseline to the intervention phase and was maintained into the withdrawal phase. Although the winners of the weekly competitions had the greatest increase in performance, non-winners also increased their instances of safe driving during the competition.     

我国商业银行竞争力研究

银行业竞争力是银行综合能力的体现。在经济全球化和金融一体化加速发展的今天,中国要想成为经济强国和金融强国,需要迅速提高中国商业银行的竞争力。因此,客观比较并切实提高中国商业银行的竞争力,对于维护金融业的健康发展具有重要意义。以往的研究往往忽略了整合城市与农村银行的竞争优势问题,而本文的创新点在于：以商业银行竞争力理论为基础,通过对于2014年年初的数据整理,将四家城市商业银行和四家农村商业银行进行对比分析,提出了要健全我国的金融市场体系,营造良好的法律环境,努力开发中间业务并建立第三方平台等解决措施。     

媒介化社会中“媒治”问题的探讨

媒介化社会的到来,使媒介的社会地位日益突出,媒介的作用也显著增强并日益受到重视.在媒介化社会中,“媒治”的呼声渐趋强烈.文章重在探讨“媒治”的正面效应和负面效应,提倡科学看待“媒治”功能,认真对待其正、负效应,主张对“媒治”进行社会监控,认为实现“媒治”与“法治”的良好结合最有利于社会发展进步.
