网络效应是指用户消费某产品的效用随着消费该类产品的总人数的增加而增加.网络效应产品因其本身的特殊性,其顾客价值构成不同于传统意义上的产品,除了有主要由产品属性决定的产品效用外,还有由网络规模决定的网络效用.在网络规模的动态演化中,网络效应分别经历了零点、启动点、饱和点,网络效应产品的顾客价值也随着发生了很大的变化.产品效用与网络效用不是以简单加总的方式,而是以交互的方式决定了网络效应产品的顾客价值.  相似文献

本文在考察网络能力与创新绩效之间的逻辑关系基础上,引入内部网络效度和合作治理方式作为调节变量,检验了企业内外部网络因素对创新绩效的影响,研究结果发现:企业网络能力和内部网络效度均对创新绩效产生显著正向影响;内部网络效度对网络能力与创新绩效的关系发挥着正向的调节效应;尽管合作治理方式对创新绩效具有正面影响,但它对网络能力与创新绩效的关系不具有调节效应;此外,企业规模对外部网络能力和内部网络效度的影响差异显著。  相似文献

Since the commercialization of the Internet, content and related applications, including video streaming, news, advertisements, and social interaction have moved online. It is broadly recognized that the rise of all of these different types of content (static and dynamic, and increasingly multimedia) has been one of the main forces behind the phenomenal growth of the Internet, and its emergence as essential infrastructure for how individuals across the globe gain access to the content sources they want. To accelerate the delivery of diverse content in the Internet and to provide commercial-grade performance for video delivery and the Web, Content Delivery Networks (CDNs) were introduced. This paper describes the current CDN ecosystem and the forces that have driven its evolution. We outline the different CDN architectures and consider their relative strengths and weaknesses. Our analysis highlights the role of location, the growing complexity of the CDN ecosystem, and their relationship to and implications for interconnection markets.  相似文献

Within this paper, a conceptualised triadic schema is hypothesised for locating emotion within a creative, learning and product orientated Design and Technology experience. The research is based upon an extensive literature review that has been synthesised and juxtaposed with the broad aspirational aims of the subject. The schema, based upon abductive reasoning and grounded theory, ultimately conceptualises the overarching theme of emotion within a creative, learning and product orientated Design and Technology experience within the Primary and Secondary stages of England’s education system. The triadic schema offers an additional opportunity in meta-theorising how the broad aspirational aims of the subject, as outlined in the English national curriculum statement of importance for Design and Technology, can be achieved through recognising the powerful overarching concept of emotion within three emerging domains: Person, Process and Product. The central tenet of this paper is the recognition of emotion within a triadic schema for meta-theorising the place of emotion within a creative, learning and product orientated Design and Technology experience. David Spendlove was previously a senior teacher in secondary education before moving into Higher Education and is now the subject leader for Design and Technology at the University of Manchester. He co-edits both Design and Technology Education: An international Journal and the DATA international research conference proceedings. He is a director of the Design and Technology Association and his research interests are broadly based around learning, pedagogy, creativity, emotion and gender.  相似文献

Childhood obesity and unhealthy nutrition are high on the European policy agenda because of their association with chronic diseases and due to the related social and economic burden. In 2014, the EU Action Plan on Childhood Obesity 2014–2020 was launched with an overarching goal to halt the rise of overweight and obesity in children by the year 2020. To facilitate the implementation of the Action Plan, the Directorate-General for Health and Food Safety of the European Commission provided support to bring together 25 Member States plus Norway for a Joint Action on Nutrition and Physical Activity (JANPA). The current paper is based on the results of JANPA and presents the explored policy options to improve children's nutrition by targeting the food environment in and around kindergartens and schools. We conclude that for effective actions countries need to combine various mutually reinforcing policies in parallel, including the provision of healthy foods, lowering the availability of unhealthy foods, restricting marketing, and promoting education. Success will depend on the coherence of messages and on the engagement of a wide range of stakeholders and sectors. Evaluation should be carefully designed, using indicators of progress towards the goal of improving diet and reducing obesity in children.  相似文献

Firms' Growth,Size and Age: A Nonparametric Approach   总被引:1,自引:0,他引:1  
This paper offers empirical evidence of firm failurerates as well as the mean of the distribution ofrealized growth rates, distinguishing between thesample of non-failing firms and the sample of allfirms, failing and non-failing. Attention is directedat identifying a set of characteristics, in particularthe size and age of firms, systematically related tothe patterns of firm growth and exit, using a panel ofSpanish manufacturing firms. The two maincontributions of the paper are the use ofnonparametric techniques and the analysis of issuesignored in other studies like theregression-to-the-mean bias and the measurement oflearning effects. We find evidence that failure ratesand the mean growth rate of successful firms declinewith size and age. When failing firms are integrated,there are no significant differences in the meangrowth rate across the age and size of firms.Regression-to-the-mean does not prove to be asubstantial factor behind the negative relationshipbetween size and growth of surviving firms.  相似文献

In Albania, many children exhibit poor nutritional status, have unhealthy diets and inadequate physical activity. Yet, comprehensive studies on the nutritional status, food and nutrition knowledge, attitudes and practices (KAP) are largely non-existent for Albanian school-age children.To fill these important gaps, a nationwide survey was conducted in Albania in 2017–2018 to assess the nutritional status and the nutrition-related KAP of Albanian school-aged children.The study consisted of a nationally representative sample of 7578 Albanian schoolchildren from all regions of the country. In addition, 6810 parent questionnaires were collected, along with interviews with the directors of all involved schools, 311 teachers and 53 key informants representing local authorities in all districts of Albania. Data collection consisted of anthropometric measurements of children and structured questionnaires administered to children, their parents, teachers, school directors, and key informants.The survey is unique in both the scope of the respondents involved, and in the breadth of content area covered, and as such, makes an important contribution not only to Albania, but also to the field of research in food, health and nutrition for school-age children.This paper presents the preliminary findings from the KAP survey that will help influence policies for actionable advancement on the commitments and priorities of Albania to improve food security and nutrition. In particular, the study findings will support the development of a national school food and nutrition programme in Albania embedded into the local food system and the design of food and nutrition educational materials and campaigns to promote healthy diets and practices among both school-age children and the Albanian population.  相似文献

网络防火墙技术浅析   总被引:2,自引:2,他引:2  
介绍了企业网络的安全屏障——防火墙的概念、作用、体系结构。互联网的资源共享与开放模式容易使网络受到黑客攻击,对于防范黑客入侵采取的主要措施是安装网络防火墙。防火墙的作用是防止不希望的、未授权的通信进出被保护的网络。任何关键性的服务器,都应放在防火墙之后。防火墙内外的计算机通信是通过代理服务器来中转实现的。本文给定了代理服务器、屏蔽路由器、双穴主机网关、被屏蔽主机网关、被屏蔽子网在防火墙内的具体实现,并对现代防火墙技术的局限性做了揭示。  相似文献

This paper outlines a selection of technological and organisational developments in the information and communication technology (ICT) sector and analyses their likely challenges for workers and trade unions around the globe. It addresses the convergence of telecommunications and information technology, the related developments of ubiquitous computing, ‘clouds’ and ‘big data’, and the possibilities of crowdsourcing and relates these technologies to the last decades' patterns of value chain restructuring. The paper is based on desk research of European and international sources, on sector analyses and technology forecasts by, for instance, the European Union and Organisation for Economic Co‐operation and Development, and some national actors. These prognoses are analysed through the lens of recent research into ICT working environments and ICT value chains, identifying upcoming and ongoing challenges for both workers and unions, and outlining possible research perspectives.  相似文献
