Relatively little research has addressed the role of LI in the perception of English speech contrasts by Chinese learners of English as L3. The present study investigates the role of LI in the perception of the English alveolar-velar nasal coda contrast (/n/ vs. /η/) after the vowels /i Λ æ/ by bilingual Changsha Chinese speakers, whose LI is Changsha Chinese and L2 is Standard Mandarin. Changsha...
Service Networks (SNs) are open systems accommodating the co-production of new knowledge and services through organic peer-to-peer interactions. Key to broad success of SNs in practice is their ability to foster and ensure a high performance. By performance we mean the joint effort of tremendous interdisciplinary collaboration, cooperation and coordination among the network participants. However,...
Closeness in meaning of the terms in the information systems and software engineering may result in discussion of using proper affiliated terms while covering the scope of research. An example is touched in this exploratory study, which discusses flexibility and its affiliated terms: changeability, adaptability, compatibility, flexibility, expandability, extendibility, extensibility and portability...
Most of the software developers are adopting the CBSE approach, to guarantee; on time delivery of software products, reduce development and maintenance cost and to improve reusability. CBSE is the development of new software by integrating built-in components. A component is a unit of composition with a well defined interface and having self-existence property. Component specification is performed...
Practitioners spend significant amounts of time creating high-level design from requirements. Though there exist methodologies to describe and manage requirements and design artifacts, there is not yet an automated way to faithfully translate a requirement into a high-level design. While it is extremely difficult to generate design elements from free-form natural language due to its inherent ambiguity,...
The complexity of today's software systems is constantly increasing. As a result, requirements for these systems become more comprehensive and complicated. In this setting, requirements engineers struggle to capture consistent and complete requirements of high quality. We propose a feedback-centric requirements editor to help analysts controlling the information overload. Our HeRA tool provides analysts...
Inter-organization collaboration is recently acknowledged as an important vision of the grid research, however there are not many well implemented system and not many applications that are in large-scale real use either. This paper present a VO (virtual organization) ontology model framework that simplifies the Inter-organization collaboration of the future grids. Thanks to the semantic technology,...
This paper addresses the questions, "Why is a test process necessary?" and "How can a "one size process "fit all lifecycles?" In answer to the first question, the paper will demonstrate that a test process based on the systems lifecycle, which is clearly understood by all stakeholders, will enable successful testing in all projects. The paper will then look at three common...
A generic test process should support all approaches "formal to informal" and mixed approaches within, and across, all test levels. But widely-accepted formal approaches, from current standards, certification syllabi and tools, have explicitly-defined test cases as the key underlying entity: not all real-life approaches use explicit test cases. Also, testing is maturing beyond merely "finding...
Due to the continuously growing possibilities provided by technology and its wider application, today's IT products are becoming more and more complex both from technical and managerial standpoints. Very often, multiple parties are involved in their development. Consequently, the organization of the integration and testing of these products gets increasingly complex. Organisations already encounter...
This position paper proposes a research agenda for the field of security testing. It gives a critical account of the state of the art as seen by a practitioner and identifies questions that research failed to answer so far, or failed to answer in such a way that it would have had an impact in the real world. Three categories of research problems are proposed: theory of vulnerabilities, theory of security...
Like RM-ODP [1], enterprise architecture (or EA for short) has its own perspectives as a basic construct for its architecture definition to represent areas of concern. In this paper, difference between RM-ODP and one concrete example EA, and applicability of Use of UML for ODP system specifications [2] (or UML4ODP in short) standard to the example EA, are discussed. Several additional diagrams that...
In this paper we propose a way to facilitate the issue of discovering the eGovernment services that address a citizen's need. This approach is implemented in an application, which we call a semantic portal. The semantic portal is part of our SemanticGov project architecture. The portal's components and its architecture are presented and explained. The portal's conceptual modeling is based on the generic...
In the current globalized world, characterized by strong Web based interactions, relationships between people and organizations are subject to fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems. Considering that some business logic portions are quite volatile and susceptible to changes and other portions...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
