On evaluating parallel computer systems

A workshop was held in an attempt to program real problems on the MIT Static Data Flow Machine. Most of the architecture of the machine was specified but some parts were incomplete. The main purpose for the workshop was to explore principles for the evaluation of computer systems employing new architectures. Principles explored were: (1) evaluation must be an integral, ongoing part of a project to develop a computer of radically new architecture; (2) the evaluation should seek to measure the usability of the system as well as its performance; (3) users from the application domains must be an integral part of the evaluation process; and (4) evaluation results should be fed back into the design process. It is concluded that the general organizational principles are achievable in practice from this workshop

Trust in ICT-Based New Product Development - Guidelines for Virtual New Product Development Teams

The traditional process of new product development is focusing on an intra-organizational workflow, which should - in its ideal form - be done by virtual interdisciplinary teams. Team members should be from several departments like manufacturing, research & development, sales and marketing. But innovation is happening more and more in networks of companies, clusters or so called network companies. The following article delivers a framework of guidelines for virtual team management in order to improve the success of innovation strategies.e-collaboration, virtual team work, new product development, Research and Development/Tech Change/Emerging Technologies,

Accessibility Evaluation of E-Government Mobile Applications in Brazil

AbstractThe provision of e-government services using mobile applications (known as m-government) has had a significant growth in recent years. However, it is very important that such applications be accessible to people with disabilities in order to ensure inclusive access. Using appropriate accessibility auditing methods is very important to help identify accessibility problems in interactive systems during their development. However, there has been little support in terms of formal standard accessibility guidelines to help develop and evaluate mobile applications. In this paper, we present a case study with the evaluation of four e-government mobile applications in Brazil using the Web Content Accessibility Guidelines (WCAG) 2.0. The paper discusses the methodological adaptations of WCAG 2.0 for the context of mobile applications and its current limitations. The results of the evaluations performed in the four applications in the case study showed that many elementary accessibility problems widely known by HCI researchers were encountered extensively in the applications evaluated. This highlights the importance of furthering research in accessibility design and evaluation of mobile applications, in order to provide more inclusive access to essential applications used by all citizens, such as e-government services

Comparative Study on Agile software development methodologies

Today-s business environment is very much dynamic, and organisations are constantly changing their software requirements to adjust with new environment. They also demand for fast delivery of software products as well as for accepting changing requirements. In this aspect, traditional plan-driven developments fail to meet up these requirements. Though traditional software development methodologies, such as life cycle-based structured and object oriented approaches, continue to dominate the systems development few decades and much research has done in traditional methodologies, Agile software development brings its own set of novel challenges that must be addressed to satisfy the customer through early and continuous delivery of the valuable software. It is a set of software development methods based on iterative and incremental development process, where requirements and development evolve through collaboration between self-organizing, cross-functional teams that allows rapid delivery of high quality software to meet customer needs and also accommodate changes in the requirements. In this paper, we significantly identify and describe the major factors, that Agile development approach improves software development process to meet the rapid changing business environments. We also provide a brief comparison of agile development methodologies with traditional systems development methodologies, and discuss current state of adopting agile methodologies. We speculate that from the need to satisfy the customer through early and continuous delivery of the valuable software, Agile software development is emerged as an alternative to traditional plan-based software development methods. The purpose of this paper, is to provide an in-depth understanding, the major benefits of agile development approach to software development industry, as well as provide a comparison study report of ASDM over TSDM.Comment: 25 pages, 25 images, 86 references used, with authors biographie

Development and User Satisfaction of “Plan-It Commander,” a Serious Game for Children with ADHD

The need for engaging treatment approaches within mental health care has led to the application of gaming approaches to existing behavioral training programs (i.e., gamification). Because children with attention deficit/hyperactivity disorder (ADHD) tend to have fewer problems with concentration and engagement when playing digital games, applying game technologies and design approaches to complement treatment may be a useful means to engage this population in their treatment. Unfortunately, gamified training programs currently available for ADHD have been limited in their ability to demonstrate in-game behavior skills that generalize to daily life situations. Therefore, we developed a new serious game (called “Plan-It Commander”) that was specifically designed to promote behavioral learning and promotes strategy use in domains of daily life functioning such as time management, planning/organizing, and prosocial skills that are known to be problematic for children with ADHD. An interdisciplinary team contributed to the development of the game. The game's content and approach are based on psychological principles from the Self-Regulation Model, Social Cognitive Theory, and Learning Theory. In this article, game development and the scientific background of the behavioral approach are described, as well as results of a survey (n = 42) to gather user feedback on the first prototype of the game. The findings suggest that participants were satisfied with this game and provided the basis for further development and research to the game. Implications for developing serious games and applying user feedback in game development are discussed
