云计算给图书馆管理带来挑战   总被引：71，自引：4，他引：67  

胡小菁  范并思 《大学图书馆学报》2009,27(4):7-12

与云计算相关的网络技术或服务,已经应用到了图书馆中。云计算将给图书馆带来巨大好处,也将给图书馆管理带来挑战。图书馆面临的管理方面的挑战包括:可替代性问题,标准问题,数据安全和保密问题,知识产权问题。为应对这些挑战,图书馆学理论界应当研究:云计算的基础理论问题,云计算在图书馆应用的可行性,图书馆云计算政策、标准与协议,基于云计算的图书馆管理体制,云计算案例。  相似文献

梦中来复少年身：谈金庸短篇小说《月云》     

廖可斌 《西南师范大学学报(人文社会科学版)》2010,(5):53-57

金庸2000年发表的短篇小说《月云》,是一篇自传色彩很浓的作品。男主人公童年宜官真诚对待弱小者丫环月云,并对她产生＂主人——婢女＂模式的朦胧情愫,整个作品流露出忆念江南的＂江南情结＂,都可以看成是金庸后来创作的武侠小说中倡导平等博爱思想、描写＂一男多女＂式情感关系、对江南和其他地域的描写笔法各异的源头。作者通过追忆童年经历,实际上为自己的武侠小说创作和人生道路做出了某种自我诠释,这篇小说是透视金庸其人及其作品的一扇窗口。  相似文献   

Computing and STEM in Greek tertiary education: gender representation of faculty members during the decade 2003–2013     

Ioannis Berdousis 《Gender and education》2018,30(1):1-21

This study focuses on the investigation of gender representation of faculty members of all ranks (professors, associate professors, assistant professors and lecturers) of Computing and STEM (Science, Technology, Engineering and Mathematics) in Greek tertiary education during the decade 2003–2013. To this end, a quantitative study was conducted, taking into account appropriate data derived from the Hellenic Statistical Authority. The data analysis shows that during the said decade, (a) faculty members in Computing and in each discipline of STEM constituted a small part of the total number of Greek faculty members; (b) for every single year of the decade, females were less prevalent than males in all ranks of faculty members in Computing and Engineering; (c) the situation for females in the Computing faculty appears to have been even worse, as the percentage of them in every rank was the lowest among the STEM disciplines studied for all or most of the years of the decade under study; and (d) although females were better represented in the position of lecturer, which constituted the fewest faculty members in the aforementioned disciplines, highly populated ranks of faculty members were dominated by males.  相似文献   

CloudChain: A novel distribution model for digital products based on supply chain principles     

《International Journal of Information Management》2018

Cloud computing is a popular outsourcing solution for organizations to support the information management during the life cycle of digital information goods. However, outsourcing management with a public provider results in a lack of control over digital products, which could produce incidents such as data unavailability during service outages, violations of confidentiality and/or legal issues. This paper presents a novel distribution model of digital products inspired by lean supply chain principles called CloudChain, which has been designed to support the information management during digital product lifecycle. This model enables connected networks of customers, partners and organizations to conduct the stages of digital product lifecycle as value chains. Virtual distribution channels are created over cloud resources for applications of organizations to deliver digital products to applications of partners through a seamless information flow. A configurable packing and logistic service was developed to ensure confidentiality and privacy in the product delivery by using encrypted packs. A chain management architecture enables organizations to keep tighter control over their value chains, distribution channels and digital products. CloudChain software instances were integrated to an information management system of a space agency. In an experimental evaluation CloudChain prototype was evaluated in a private cloud where the feasibility of applying supply chain principles to the delivery of digital products in terms of efficiency, flexibility and security was revealed.  相似文献   

改进的切片法三角化     

陈新河 《巢湖学院学报》2009,(3):54-57

空间点云的三角化问题是立体视觉等众多领域中的一个热点研究问题.当前相关文献只有少量的介绍了空间闭合点云的三角化方法,而这些方法中又只有为数不多的能对表面曲率变化剧烈的空间点云进行三角化.本文通过对医学断面法和增量算法的结合、改进,来处理空间闭合散乱点云的三角化问题,不但能对空间普通形状闭合点云进行三角化,而且对表面曲率变化剧烈的空间闭合点云也可以进行正确的三角化.实验表明,本方法三角化速度快,产生的三角面片质量高.  相似文献
