public participation in proprietary software development through user Roles and discourse
International Journal of Human-computer Studies \ International Journal of Man-machine Studies, 2008Co-Authors: David G HendryAbstract:The opportunity for users to participate in design and development processes has expanded in recent years through such communication and information technologies as mailing lists, bug trackers, usage monitoring, rich interactions between users and service-center staff, remote usability testing, and so on. A key question, therefore, is deciding how to engage users in design and development through such technologies. This paper addresses this question by reviewing literature on end-user programming and open source development to develop a framework concerning user Roles and discourse. The framework makes two claims: (1) user Roles and a social structure emerge after the introduction of a software Application (Role differentiation); and (2) different Roles demand different kinds of discourse for deciding what to do and for reflecting upon intended and unintended consequences (Role discourse demands). To show its Application, the framework is used to analyze the development of del.icio.us, a breakthrough Application for social bookmarking. This development process is notable because it is a characteristic of open source software development in some respects, but the code is not made available publicly. This hybridization appears to be widely applicable and suggests how design and development processes can be structured as a service where the design and development of the system proceeds simultaneously with the formation and nurturing of a community of users.

investigation of the origin of v_ t v_ rm fb modulation by hbox la _ 2 hbox o _ 3 capping layer approaches for nmos Application Role of la diffusion effect of host high k layer and interface properties
IEEE Transactions on Electron Devices, 2011Co-Authors: Bongmook Lee, Steven Novak, Daniel J Lichtenwalner, Xiangyu Yang, Veena MisraAbstract:The Role of La2O3 capping in the VT/VFB shift with various high- k and metal gate electrodes was systematically investigated. It was found that the La concentration at the high-k/SiO2 interface is mainly responsible for the VT/VFB modulation in NMOS devices, whereas the effect of the host high-k and gate electrodes on VT/VFB is minimal. A 400-mV shift in VT from the control HfO2 device with minimal degradation in mobility was obtained when a La2O3 layer was inserted between the high-k and SiO2 layers. It was also found that the incorporation of La2O3 in the dielectric stack improves device reliability in terms of breakdown and positive-bias temperature instability characteristics. The main key for the VFB shift is the ability of La diffusion through the host high-k material.

the early warning Application Role in facing the environmental crisis and disasters preliminarily risk management strategy for the greater city of cairo
Spatium, 2013Co-Authors: Yousef M Ghoneem, Ahmed Khaled Ahmed ElewaAbstract:Natural disasters are inevitable and it is almost impossible to fully recoup the damage caused by the disasters. But it is possible to minimize the potential risk by developing disaster early warning strategies, methods using the new technology Applications which play a crucial Role in efficient mitigation and management of disasters. This paper describes the importance of the remote sensing and Geographical Information System (GIS) in evolving a suitable strategy for disaster, crises and risk management using these technologies. The main objective of this paper is to make a Preliminary risk management plan (it is a logical and systematic method of identifying, analyzing, treating and monitoring the risks involved in any activity or process. This process helps Administrations to focus on priorities and in decisions on deploying limited resources to deal with the highest risks) using the Environmental risk map of the greater city of Cairo demonstrating the most high-risk administrative areas in the city, supported by field evidence and different sources of information. to reduce the loss of life and property and protect the Nation from all hazards, including natural disasters and other man-made disasters, by leading and supporting the Nation in a risk-based, comprehensive emergency management system of preparedness, protection, response, recovery, and mitigation. This study has shown that how can the early warning Applications can be useful in analyzing, Integrating and managing different datasets for predicting the environmental crises and disasters that may affect the urbanism inside the city and help in the preparation of the Risk management plan.
