Developing Distributed System with Service Resource Oriented Architecture

 Service oriented architecture (SOA) is a design paradigm in software engineering for an enterprise scale which built in a distributed system environment. This paradigm aims at abstracting of application functionality as a service through a protocol in web service technology, namely simple object access protocol (SOAP). However, SOAP have static characteristic and oriented by the service methode, so have restrictiveness on creating and accessing for big numbers of service. For this reason, this reasearch aims at combining SOA with resource oriented architecture (ROA) that is oriented by the service resource use representational state transfer (REST) protocol in order to expand scalability of service. This combination is namely service resource oriented architecture (SROA). SROA can optimize distributing of applications and integrating of services where is implemented to develop the project management software. To realize this model, the software is developed according with framework of Agile model driven development (AMDD) to reduce complexities on the whole stage processing of software development

A Knowledge-Constrained Role-Based Access Control model for protecting patient privacy in hospital information systems

Current access control mechanisms of the hospital information system can hardly identify the real access intention of system users. A relaxed access control increases the risk of compromise of patient privacy. To reduce unnecessary access of patient information by hospital staff, this paper proposes a Knowledge-Constrained Role-Based Access Control (KCRBAC)model in which a variety of medical domain knowledge is considered in access control. Based on the proposed Purpose Tree and knowledge-involved algorithms, the model can dynamically define the boundary of access to the patient information according to the context, which helps protect patient privacy by controlling access. Compared with the Role-Based Access Control model, KC-RBAC can effectively protectpatient information according to the results of the experiments

Institutional Viewpoint on Wireless Standardisation Process

The complexity of organizational and technological changes confronting most organizations has made an organizational change and adaptation a topical research question. This paper examines the process of wireless standardization viewpoint and sets out a framework for understanding organizational changes in wireless standardization organizations by applying institutional theory. It is concluded that such a framework can reveal more about the changes occurrence in standardization processes

National Land Coalitions and the Preservation of Communities’ Ancestral Land Heritage in Africa

National Land Coalitions (NLCs) work towards the recognition, defence, protection and redistribution of land rights at national level. They build upon frameworks on land tenure developed and agreed by different regional and intergovernmental institutions. Platforms are at the heart of protecting and preserving community and customary lands which constitute the major category of landholding in Africa. The purpose of this paper is threefold: share the successes of National Land Coalitions in selected countries in securing the land heritage for communities and other vulnerable groups; identify the ingredients for such successes including enabling factors and methods used; identify the bottlenecks and threats faced by the actors involved in these coalitions; as well as possible opportunities and recommendations to better capacitate these platforms in achieving their mandate. The analytical framework is based on three components of the syntax namely the Attribute, aIm, and Condition (AIC). The Attribute focuses on the organizational description, the aIm puts emphasis on the coalition’s goal, while the Condition highlights the means coalitions put at the service of their ambition. We undertook a literature review and three case studies serve as basis to analyse the contribution of National Land Coalitions to community land preservation. These include in Cameroon the Banen community in the Ebo Forest, and the land concessions in the Ntem Valley, and in Sierra Leone the palm oil investment by Socfin in the Malen Chiefdom. It is demonstrated that NLC actions and activities have contributed to increasing the preservation of community lands. These Coalitions emerge in a context of arable land scrambling, the adoption and implementation of new progressive land policies and laws that promote and protect community and customary land rights. Through intense policy dialogue, advocacy, and capacity strengthening, facilitated and supported by NLCs, more and more communities are in position to fight land dispossession by states and private actors. However, these Coalitions face challenges that hamper their action, including organizational structure, power asymmetries, financing and sustainability issues. In terms of opportunities, an increasing number of national legislative frameworks are being reviewed and land governance monitoring instruments like the LandMatrix and the LANDex are taken to scale. Spaces such as LandCollaborative put national platforms at the centre of people-centered land governance and facilitate horizontal learning between platform practitioners across countries in Africa

Physical processes, their life and their history

Here, I lay the foundations of a high-level ontology of particulars whose structuring principles differ radically from the 'continuant' vs. 'occurrent' distinction traditionally adopted in applied ontology. These principles are derived from a new analysis of the ontology of “occurring” or “happening” entities. Firstly, my analysis integrates recent work on the ontology of processes, which brings them closer to objects in their mode of existence and persistence by assimilating them to continuant particulars. Secondly, my analysis distinguishes clearly between processes and events, in order to make the latter abstract objects of thought (alongside propositions). Lastly, I open my ontological inventory to properties and facts, the existence of which is commonly admitted. By giving specific roles to these primitives, the framework allows one to account for static and dynamic aspects of the physical world and for the way that subjects conceive its history: facts account for the life of substances (physical objects and processes), whereas events enable cognitive subjects to account for the life story of substances
