A trend running diametrically opposed to the expansion of Intellectual Property Rights (IPR) is the increasing awareness that dominant positions sustained by IPR may be mitigated through exemptions and statutory or compulsory licences. It is argued that there are compelling economic reasons to protect valuable assets that are prone to copying, but that there are equally compelling reasons to limit monopolistic claims and stimulate cross-licensing practices. Compulsory licensing may serve as a stimulus to the bargaining process with private parties and research institutions alike. Another important category of information is public sector information. Access to information has become a concern and the European Commission has followed up on its Green Paper on Public Sector Information in the Information Society, with a Directive implementing its vision on affordable access for all and exploitation potential. The right of access to information may be enforced through the European Convention on Human Rights. It not only guarantees the freedom of speech, it also recognises the freedom to receive information. 相似文献

The apo E gene located on chromosome 19 in humans is polymorphic. The three apo E isoforms E2, E3, and E4 are coded by three
common alleles of the gene. The amyloid plaques in brains of Alzheimer disease (AD) patients are known to contain apo E. There
is an increased prevalence of E4 allele in AD patients. apo E exhibits increased binding to a peptide Aβ deriving from amylold
precursor protein. apo E, the risk factor for late AD disease is unable to prevent formation of paired helical filaments which
in turn destabilizes neuronal microtubules.
A variety of molecular techniques are available for apo E genotyping using DNA amplified by the polymerase chain reaction
(PCR). The high guanine to cytosine content of apo E is problematic to the extent that the yield of PCR product and hybridization
stringency can be compromised. The specificity of diagnosis of late-onset AD can be improved when results of apo E genotyping
are evaluated together with clinical criteria. 相似文献

摘要：随着企业的经营模式从以产品为核心到以客户为核心的转变,客户关系管理（CRM）的重要性日益显现。CRM应用实践表明,对CRM内涵和本质的认识不同往往造成CRM应用效果上的巨大差别。本文从价值创造的视角来研究客户关系管理,并基于价值创造从理念层、制度流程层和技术层三个层次来认识和理解客户关系管理。本文以保险公司为例,按照企业价值链从保险产品开发、产品营销、保险理赔和保险投资四个方面探讨了客户关系管理价值创造的机理。最后围绕价值创造这个核心,本文提出了将企业的内部条件和外部环境结合起来统一考虑,从公司战略、组织结构和业务流程、技术架构三个方面构建实施客户关系管理系统的框架和推动实施客户关系管理的策略。 相似文献

Although digital content (DC) business has been increasingly recognized as one of the core industries in a knowledge-based economy, little is known about its value stream from DC users’ perspective. This study suggests a DC value chain framework involving the stream of DC value from DC creation to use from users’ perspective, which has three key components of DC-value stream: (1) DC-value creation, (2) DC-value interaction, and (3) DC-value use. Drawing upon the DC value chain framework, we propose a research model exploring the direct relationships between DC-value creation and DC-value interaction and between DC-value interaction and DC-value use. It also explains the moderating role of DC types between DC-value and DC-value interactions. The empirical results of the study indicate that DC-value interactions play an intermediary role between DC creation value and DC use value and that users’ perceptions of DC value vary in different types of DC. We discuss theoretical contributions and practical implications along with some avenues for future research. 相似文献

The case study illustrates another genre of the B2E (business to employee) model, implemented at a large Indian IT organisation to engage its employees in order to create value for its customers. The main focus of the empirical analysis is the counterintuitive strategy to ensure customer loyalty and increased revenues by transforming the relationship between the management and the employees. A brief outline is presented of the B2E model and a case analysis of issues is derived. 相似文献

对价值链概念首创者－迈克尔·波特的"价值"概念进行剖析,解释了其用价格分析取代价值分析的理论背景,并得出价值链价值实现的出发点为顾客价值的结论;通过对价值链进一步分析,说明解构传统的"纵向一体化"价值链成为必然,而分散的链环将导致实物流、资金流与信息流的分离,使得价值链的价值实现的成败反映在企业对资金、信息与实物的驾驭能力上;而管理的工作将是对实物流、资金流与信息流的运作、跟踪、监控、预测与决策。 相似文献

Digital inclusion research has focused overwhelmingly on access to information. But access to information by itself is of limited value unless the intended beneficiary has the capacity to use it. It is the use of information that delivers the benefits. However, in information and communication technologies for development literature, there is little empirical work on the process by which use of information delivers benefits. This study fills the gap by studying information use by poor female mobile phone users in rural India. It identifies six stages in the information use process and models them. 相似文献

Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to focus on the continuity of the resources and processes through which a particular business model is accomplished in practice but omit the business model itself. We argue that in order for BC approaches to become holistic and strategic, business models need to become a part of the BC considerations, entailing an expansion of the scope of BC from value preservation to value creation. We propose an approach of Strategic Business Continuity Management, which consists of two parts: (1) sustaining the continuity of the company business model (value preservation) and (2) evaluating and modifying the business model (value creation). We illustrate conceptually the value creation part with an example drawn from the sharing economy. 相似文献
