A Metrics Approach for Collaborative Systems

This article presents different types of collaborative systems, their structure and classification. This paper defines the concept of virtual campus as a collaborative system. It builds architecture for virtual campus oriented on collaborative training processes. It analyses the quality characteristics of collaborative systems and propose techniques for metrics construction and validation in order to evaluate them. The article analyzes different ways to increase the efficiency and the performance level in collaborative banking systems.collaborative system, collaborative learning, virtual campus, banking, metric

Impact of Information and Communication Technology (ICT) on construction projects

The changing face of construction projects has resulted in a movement towards the use of technology as a primary means of communication. The consequences of this rise in the use of information and communication technology (ICT) is a loss of interpersonal communication skills. A number of resulting issues within the human – electronic and human – human interfaces are identified in an attempt to define the efficiency of communication in projects. The research shows how ICT effects the social environment of construction project teams and the project outcome. The study seeks to confirm the need for further work in order to develop new forms of communication protocols and behaviour. An initial literature review was undertaken to develop a theoretical review of the impacts of ICT on construction project teams. This review identified a number of issues that were then tested in the field through an observation and two verification interviews. The research confirms the existence of tensions and conflicts in the human – electronic and human - human communication interfaces within the studies environment. It is proposed that the increasing use of ICT occur at the expense of soft system communication. The principal impact of this is a form of ‘human distraction’ which adversely affects the performance of project teams. There is limited theory exploring these issues that suggests the problems identified are not well understood and consequently indicates a gap in knowledge

Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach

Unified Modelling Language (UML) is the most popular modelling language use for software design in software development industries with a class diagram being the most frequently use diagram. Despite the popularity of UML, it is being affected by inconsistency problems of its diagrams at the same or different abstraction levels. Inconsistency in UML is mostly caused by existence of various views on the same system and sometimes leads to potentially conflicting system specifications. In general, syntactic consistency can be automatically checked and therefore is supported by current UML Computer-aided Software Engineering (CASE) tools. Semantic consistency problems, unlike syntactic consistency problems, there exists no specific method for specifying semantic consistency rules and constraints. Therefore, this research has specified twenty-four abstraction rules of class‟s relation semantic among any three related classes of a refined class diagram to semantically equivalent relations of two of the classes using a logical approach. This research has also formalized three vertical semantic consistency rules of a class diagram refinement identified by previous researchers using a logical approach and a set of formalized abstraction rules. The results were successfully evaluated using hotel management system and passenger list system case studies and were found to be reliable and efficient

'Any Portal in a Storm?' Online Engagement Patterns of First Year QUT Students

Engaging new students in tertiary study, amidst the storm of their adjustment to university life, should harness conventional physical as well as new virtual spaces to ensure (as urged by McInnis 2003, p.9) learning opportunities are maximised inside and outside of the classroom. When ubiquitous information, merged technologies, blurred social-study-work boundaries, multitasking and hyperlinked online interactions epitomise generational routines (Oblinger & Oblinger, 2005); positive, rewarding interactions through virtual space "portals" may establish the mode and intensity of on- and off-campus student experience. Conventional modes of curriculum delivery and learning support that hinge on presentation of material according to (for example) scheduled topic sessions, contact times and administrative office hours, do not necessarily fully accommodate these new social realities (James, 2002, p.81), contemporary learning practices or transition-informed curriculum design (Kift, 2005). In this paper, quantitative data and rich qualitative information from internal and external surveys are triangulated to examine the patterns of online engagement for students at QUT. These patterns inform our ongoing project that seeks to tailor the delivery of curriculum mediated resources within a virtual space

Learning Lessons with Knowledge Audits

{Excerpt} Knowledge from evaluations will not be used effectively if the specific organizational context, knowledge, and relationships of evaluation agencies, and the external environment they face, are not dealt with in an integrated and coherent manner. Knowledge management can shed light on this and related initiatives can catalyze and facilitate identification, creation, storage, sharing, and use of lessons. Most development agencies have committed to become learning organizations. But the use of evaluation for learning may be less important than that of other inputs, such as self evaluation and training, and evaluation results may only marginally support policy, strategy, and operational changes. In 2006, the Independent Evaluation Department in the Asian Development Bank determined to apply knowledge management to lesson learning. In 2007, it formulated a strategic framework to improve the organizational culture, management system, business processes, information technology solutions, community of practice, and external relations and networking for that. These Knowledge Solutions explain the strategic framework. They also describe the knowledge audit methodology developed to tie in with the department’s audiences. The online, questionnaire-based survey of perceptions conducted as a first exercise that year provided ready and multiple entry points against which the department can take measures to that intent, as well as a comprehensive baseline assessment against which to judge progress. Fundamentally, these Knowledge Solutions contend that evaluation agencies should move from “make-and-sell,” at the simplest level, to “sense-and-respond” in ways that are increasingly satisfying to stakeholders. Knowledge from evaluations will not be used effectively if the specific organizational context, knowledge, and relationships of evaluation agencies, and the external environment they face, are not dealt with in an integrated and coherent manner. Knowledge management can shed light on possible operating frameworks for this and knowledge management initiatives can be applied to catalyze and facilitate identification, creation, storage, sharing, and use of lessons. That would be knowledge utilization indeed

Symmetric Synchronous Collaborative Navigation

Synchronous collaborative navigation is a form of social navigation where users virtually share a web browser. In this paper, we present a symmetric, proxy-based architecture where each user can take the lead and guide others in visiting web sites, without the need for a special browser or other software. We show how we have applied this scheme to a problem-solving-oriented e-learning system
