System Support for Managing Invalid Bindings

Context-aware adaptation is a central aspect of pervasive computing applications, enabling them to adapt and perform tasks based on contextual information. One of the aspects of context-aware adaptation is reconfiguration in which bindings are created between application component and remote services in order to realize new behaviour in response to contextual information. Various research efforts provide reconfiguration support and allow the development of adaptive context-aware applications from high-level specifications, but don't consider failure conditions that might arise during execution of such applications, making bindings between application and remote services invalid. To this end, we propose and implement our design approach to reconfiguration to manage invalid bindings. The development and modification of adaptive context-aware applications is a complex task, and an issue of an invalidity of bindings further complicates development efforts. To reduce the development efforts, our approach provides an application-transparent solution where the issue of the invalidity of bindings is handled by our system, Policy-Based Contextual Reconfiguration and Adaptation (PCRA), not by an application developer. In this paper, we present and describe our approach to managing invalid bindings and compare it with other approaches to this problem. We also provide performance evaluation of our approach

Evaluating Integration Approaches Benefits Adopted by Healthcare Organizations

Healthcare organizations consist of a large number of disparate information systems (IS). These have been deployed to support specific needs of healthcare organisations. The information sharing among these disparate and heterogeneous systems has always been one of the most prominent issues for the management. As every day people die in hospitals, due to medical errors, which is generally causes due to non-integrated IT infrastructure. Various integration approaches have been adopted to solve integration problems. Although, some of them have partially supported the integration efforts, there are still many issues remaining to be solved such as level of integration, interpretability, cost reduction, and patients’ data security. There is marketplace confusion in healthcare organisations, due to the variety of integration approaches that support the integration of healthcare IS. This paper seeks to describe the current deployed integration approaches in healthcare organisations. In doing so, the benefits of these approaches are evaluated. This evaluation will help researchers to better understand issues surrounding the benefits of integration approaches

Investigating Identity Fraud Management Practices in E-tail sector:A Systematic Review

Purpose: Identity fraud is a growing issue for online retail organisations. The literature on this issue is scattered, and none of the studies presents a holistic view of identity fraud management practices in the online retail context. Therefore, the purpose of this paper is to investigate the identity fraud management practices and present a comprehensive set of practices for e-tail sector. Design/methodology/approach: A systematic literature review approach was adopted, and the articles were selected through pre-set inclusion criteria. The authors synthesised existing literature to investigate identity fraud management in e-tail sector. Findings: The research finds that literature on practices for identity fraud management is scattered. The findings also reveal that firms assume identity fraud issues as a technological challenge, which is one of the major reasons for a gap in effective management of identity frauds. This research suggests e-tailers to deal this issue as a management challenge and counter strategies should be developed in technological, human and organisational aspects. Research limitations/implications: This study is limited to the published sources of data. Studies, based on empirical data, will be helpful to support the argument of this study; additionally, future studies are recommended to include a wide number of databases. Practical implications: This research will help e-tail organisations to understand the whole of identity fraud management and help them develop and implement a comprehensive set of practices at each stage, for effective management identity frauds. Originality/value: This research makes unique contributions by synthesising existing literature at each stage of fraud management and encompasses social, organisational and technological aspects. It will also help academicians understanding a holistic view of available research and opens new lines for future research.</p

Issues & Challenges in Urdu OCR

Optical character recognition is a technique that is used to recognized printed and handwritten text into editable text format. There has been a lot of work done through this technology in identifying characters of different languages with variety of scripts. In which Latin scripts with isolated characters (non-cursive) like English are easy to recognize and significant advances have been made in the recognition; whereas, Arabic and its related cursive languages like Urdu have more complicated and intermingled scripts, are not much worked. This paper discusses a detail of various scripts of Urdu language also discuss issues and challenges regarding Urdu OCR. due to its cursive nature which include cursiveness, more characters dots, large set of characters for recognition, more base shape group characters, placement of dots, ambiguity between the characters and ligatures with very slight difference, context sensitive shapes, ligatures, noise, skew and fonts in Urdu OCR. This paper provides a better understanding toward all the possible engendering dilemmas related to Urdu character recognition
