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.     

多复变数的黎曼边值问题

利用Bochner-Martinelli型积分工具,讨论Cn空间中具有逐块C(1)闭光滑边界流形的单连通区域D的黎曼边值问题;并在L*空间中给出了黎曼边值问题的唯一解。此问题的特征之一是其边界系数不出现指标。

关于Riemann可积性

证明了定义在有界闭区间上的有界函数Riemann可积的充分必要条件是它的左端点和有极限，即证明∫a^bf(x)dx=lim λ→0 ∑i=1^nf(xi-1)Δxi，λ=max|Δxi|其中xi是区间的分点，这个结果把Riemann积分定义中区间的分法和点的取法两个任意减弱为一个，即区间的分法任意，点的取法则固定选取小区间的左端点．
