Web服务日益成为异构网络环境下的主流分布式计算模式.基于XML的数据传输格式在给Web服务带来跨平台性、松散耦合和良好的互操作性等优点的同时,也在一定程度上影响了其性能.Web服务的性能成为决定其是否能进一步得到更加广泛应用的关键因素之一.在分析Web服务性能的基础之上,针对Web服务的额外性能开销问题,以.NET平台为例,提出了使用缓存技术、SOAP压缩技术和异步Web技术等策略实现Web服务性能的优化. 相似文献

对全国31个省市理工类院校和北京地区22所理工类高校实验教师队伍的现状调查发现,实验教师队伍发展的现状不容乐观,主要表现为传统的实验教学思路和观念的偏差,实验教师队伍建设政策的缺失,对实验教师队伍建设缺乏规划。实验教师队伍建设发展对策应着重于以下几方面:制定高校实验室教师发展的策略,合理构建实验教师队伍;健全体制、优化实验教师发展平台,建立完善的政策环境、新型实验教学体系、规范高效的运行机制以及科学的考评机制。 相似文献

This paper reports on a study that investigated the range of institutional support needs of international students at one Australian university with a view to increasing understanding of their needs and the ways in which support was provided. The study involved a number of data collection methods including focus groups, key informant interviews and a larger scale survey, undertaken in an inductive and sequential process. The results indicated that the levels of awareness about services differed, that lack of knowledge of how to access a service and finding information about it were key reasons for non-use, and that the helpfulness of staff impacted on the perception of services as useful. The paper concludes by recommending a reconsideration of current practices to move towards a model of student support service provision in which the student is at the centre. 相似文献

Comparable scales to measure quality of early intervention services for infants and toddlers as perceived by parents and service providers were developed based on the Recommended Practices in Early Intervention. Each scale consisted of four subscales focusing on: home-based therapies/instruction, centre-based therapies/instruction, medical/ health services, and service coordination. The scales were administered to 209 parents and 177 of their service providers. A sample of 24 parents completed the instrument twice during a two-week interval to assess test-retest reliability of the parent scale. Test-retest reliability for the parent scale was .785. Validity of the scale was assessed by examining the correlation of parent and provider perceptions of quality with family demographic and early intervention service characteristics. Parents' perceptions of quality were related to family centredness of services. Neither parents' nor providers' perceptions of quality were related to family socioeconomic status. Problems and prospects for measuring quality of early intervention services are discussed. 相似文献

With the rapid growth of service scale, there are many services with the same functional properties but different non-functional
properties on the Internet. There have been some global optimizing service selection algorithms for service selection. However,
most of those approaches cannot fully reflect users’ preferences or are not fully suitable for large-scale services selection.
In this paper, an ant colony optimization (ACO) algorithm for the model of global optimizing service selection with various
quality of srevice (QoS) properties is employed, and a user-preference based large-scale service selection algorithm is proposed.
This algorithm aims at optimizing user-preferred QoS properties and selecting services that meet all user-defined QoS thresholds.
Experiment results prove that this algorithm is very efficient in this regard. 相似文献

Formal models for service composition have been proposed with the variation of the requirements of service developers. Some
famous models have provided checking and verification techniques and tools for the behavior of service composition. These
models generally focus much on the message flow of web services and neglecting the data contained in the exchanged messages
among services, which restrict the application range of these models and also the web service techniques. As new kind of services
with different protocols and communication methods have appeared, it is needed to model service composition from a new view
which is adapted to the new development in service area. In this paper we offer a function oriented model of service composition
which treats the composite service as a software system and specify the function of services which can be directly used to
the realization by service providers. 相似文献

This article describes a study by co-integration test and Granger causality test on the relationships between China's services trades and employment using the data of services trade from the WTO website and the employment data from China Statistic Yearbook for the years from 1982 to 2003. Co-integration test showed that 1% increase in export value and import value of services created respectively 0.205% and 0.068 7% more job opportunities in the service sector. Both export and import of services impacted positively on employment in service industry, and export did more than import. However, in the short run, the impacts of services export and import on employment in service industry were both very small, though positive; and the impacts of employment in service industry on both export and import of services were very big, but not stable. Granger causality test indicated that employment in service industry was a Granger cause of services export. The findings highlight the importance of facilitating services import and reducing import barriers, and suggest that the competitiveness of China's labor- intensive services trade can be exploited to boost services export and help employment in service sector, and that the structure of services trade should be optimized by shifting from labor-intensive to knowledge-and technology-intensive services thus to enhance China's competitiveness of services export. 相似文献
