一种基于信号机制在UNIX实时应用中快速传递信息的方法

在多进程的实时应用程序中，进程之间往往需要通过传递一些信息来达到资源共享的目的。介绍了一种基于信号机制在UNIX实时应用中的两个进程之间实现快速传递信息的方法，提高了实时性。     

The Disciplining Role of Accounting in the Long-Run

One role of accounting is to discipline softer (more manipulable) sources of information. We use a principal-agent model of hidden actions and hidden information to study this role. In our model, there is both a verifiable signal (a publicly observed output) and an unverifiable signal (a productivity parameter privately observed by the agent). In a one-period setting, the optimal contract does not make use of the agents report on the private signal. However, when the output is tracked over two periods, the agents communication can be valuable. This reversal of results suggests uncovering the disciplining role of accounting may require a long-term perspective.JEL Classification: D82, M41     

相关瑞利衰落信道下空时分组编码性能分析

目前对空时编码的研究大都是基于信道是独立的假设下进行的,然而在实际系统中独立性假设是不成立的。基于此,研究了信道的相关性对空时编码性能的影响。计算机仿真结果表明：由于衰落信道的相关性,系统性能有所下降,且系统性能关于相关系数存在“地板效应”,即相关系数小于某一数值时,对系统性能的影响较小;当大于此值时,系统性能就会急剧下降。     

Marketing of competence: Exploring the resource-based content of value-for-customers through a case study analysis

In this article, we propose a competence-based view of value-for-customer in business markets. While literature in both strategy and marketing has provided many insights to understand the competence-based roots of value creation, the interface between the two areas is still largely unexplored. Moreover, while the notions of competence exchange and value creation feature strongly in the relational perspective, they occur only once relationships have been established. This begs the question whether competencies could be developed outside established relationships, and then marketed to guide customers' buying behavior. Basing on three case studies from the yarn manufacturing, IT systems, and automotive components industries, we identify key features of competence-based marketing: the alignment of supplier's competencies with the customer's business processes, the experiential communication of supplier's competencies, and the delivery of competencies to the buyer's business processes. Within the strategies for creating value-for-customers, these findings contribute to the understanding of the use of competencies to induce purchases.

银行跨国并购中的文化差异识别体系研究

在跨国并购中,并购银行将面临民族文化和企业文化双重差异和冲突带来的挑战,而且缺乏对文化差异的理解和管理是并购失败的首要原因。在并购实施中,我们有必要把文化整合与业务技术整合看成截然不同但又紧密相关的两个领域,而构建文化差异识别体系是文化整合的基础。本文从感知跨国并购中的文化差异冲突和融合入手,提出构建文化差异识别体系应以整合战略执行为导向,突出促成行为改变的关键要素;提出了涵盖人本文化、处事文化、沟通文化等角度,共7个维度、22种偏好的文化差异识别体系的基础框架。     

今道有信:技术联结时代的爱

今道有信在《关于爱》中探讨了技术关联时代爱的危机和继续存在的可能性;在《关于美》中,就爱与美的关系提出了"美是存在的恩惠和爱"的命题,将爱置放在了现代性语境中,并赋予它以存在论的意义,但全部讨论没有脱离精神现象学的视野,没有摆脱意识——理念——艺术的范围。美存在于人类生命的根底部,是人类的生存方式和表征;现代社会爱的危机首先是美,即生存本身的危机,因此,对爱的命运的探讨和爱的形而上学的建构只能立足于存在论。     

基于识别度与传播能力的品牌竞争力评价

品牌识别度与品牌传播能力两项指标,表现了品牌和消费者心理、行为之间的互动、多变的关系。基于这种认识,本文构建了品牌识别度与品牌传播能力的评价指标体系,用层次分析法来计算影响品牌识别度与传播能力的指标的权重,再用模糊综合评价法来进行具体评价,并借助于德尔菲打分法,设计了一个基于品牌识别度与品牌传播能力的品牌竞争力二维评价模型,在此基础上,以"苏宁电器"为例进行具体的案例分析。     

Organisational Change through Collaborative Learning in a Network Form

In view of the changing nature of organisations, their structures and processes, managing organisational change is seen to be an ongoing challenge. In this paper, organisational learning is considered to be a potent force that drives organisational change. The use of an electronic group communication system supporting a distributed work process is explored in a network form of organisation. Following an analysis of the patterns of behaviour that occur within an evolving electronic social space, this paper concludes with a discussion of the implications for managing change through learning in a network form of organisation.
