Facilitating enterprise application integration adoption: An empirical analysis of UK local government authorities

local government authorities (LGAs) are organised around operational structures with business processes spanning within departments and across other government organisations. In such an organisational setting, the harmonisation of Information Technology (IT) operations, integration of cross-departmental processes and the underlying Information Systems (IS) signifies a challenge in delivering integrated services. This paper attempts to explore enterprise application integration (EAI) adoption in the UK local government authorities (LGAs). Despite the hype of EAI adoption in private domain, its application in LGAs is inadequate as there is a lack of adoption models/frameworks that can be used by the public sector. The context of the study is to consider the transformation of IT infrastructure management and operations with EAI technologies. The empirical findings, generated through a detailed case analysis, manifestly exemplify that EAI predominantly acts as a ‘back-office’ technology that facilitates operations by developing a flexible and maintainable integrated IT infrastructure. Our proposed framework is believed to be imperative and unique as it provides a more systematic way to examine the adoption of integration technologies, extends the established norms for EAI adoption by utilising a prioritisation technique to classify the importance of factors. The contribution of the research extends the literature on EAI and identifies theoretical and practical opportunities that facilitate LGAs in their decision-making process to produce more robust proposals for EAI adoption.     

关于Gelfer函数

我们称单位圆盘中的解析函数f(z)=1+(sum from n=1 to ∞)a_nZ~n为Gelfer函数,如果对一切Z,∈△,都有f(z)+f(C)≠0。文〔1〕中关于Gelfer函数提出了若干问题,我们解决了其中的两个。     

Hibernate中关联关系映射策略研究与实现

为解决对象模型和关系模型之间的不匹配,引入对象关系映射框架来解决。Hibernate是目前主流的ORM映射框架。分析了Web应用程序的体系结构和Hibernate体系结构。以在线购物系统为例,给出了对象关联关系映射策略,通过映射文件实现了该映射策略。实验结果表明,映射文件成功实现了该映射策略。通过Hibernate的数据持久层解决方案,提高了数据存取的速度,降低了系统的耦合性,保证了系统的扩展性。     

Preparing literary material for public utterance

This essay claims that arguments about the genres of discourse contain as a crucial element an attribution of status, which involves a dialectic of authority and marginality. Rhetorical scholarship is often a reaction against the condition of marginality. Reflection on these matters illumines the ontology of rhetorical discourse.     

How a qualitative approach to concept map analysis can be used to aid learning by illustrating patterns of conceptual development

This paper describes a qualitative approach to analysing students' concept maps. The classification highlights three major patterns which are referred to as 'spoke', 'chain' and 'net' structures. Examples are given from Year 8 science classes. The patterns are interpreted as being indicators of progressive levels of understanding. It is proposed that identification of these differences may help the classroom teacher to focus teaching for more effective learning and may be used as a basis for structuring groups in collaborative settings. This approach to analysing concept maps is of value because it suggests teaching approaches that help students integrate new knowledge and build upon their existing naive concepts. We also refer to the teacher's scheme of work and to the National Curriculum for science in order to consider their influence in the construction of understanding. These ideas have been deliberately offered for early publication to encourage debate and generate feedback. Further work is in progress to better understand how students with different conceptual structures can be most appropriately helped to achieve learning development.
