An investigation of web-based hypermedia design support: methods and tools

Since the Internet networking was first established, the World Wide Web (or WWW) provides a new opportunity to deliver information and to communicate with others. Therefore, many organisations and industries have joined this exciting technology to take advantage of the Web. In recent years, the opportunity has arisen for other tasks to be carried out on the Web apart from delivering information. As the Web applications and documents have become larger and more complex, they have experienced many design and development problems which often lead to very high maintenance cost. To improve the quality of Websites and the structure of information, the designers need structured design methods, guidelines, and tools to assist their work. Some researchers have proposed hypermedia design methods and guidelines, which contain development cycle with formal design techniques to assist the construction of Web page designs. To overcome the design and development problems, this research is carried out by surveying currently available design methods. It shows the ways to apply these methods for developing structured Web sites. The results of this research led to identifying the design stages involved in developing Web sites using hypermedia methods. It also presents a CASE tool to provide a development environment for producing Web pages based on hypermedia design stages. This encourages Web designers to apply structured hypermedia design methods to improve the quality of design and to reduce the maintenance cost. The thesis is relevant for end-users, Web designers from organisations, institutes, and institutes for those who want to apply structured hypermedia design methods for producing their Web documents

Attribute based component design: Supporting model driven development in CbSE

In analysing the evolution of Software Engineering, the scale of the components has increased, the requirements for different domains become complex and a variety of different component frameworks and their associated models have emerged. Many modern component frameworks provide enterprise level facilities and services, such as instance management, and component container support, that allow developers to apply if needed to manage scale and complexity. Although the services provided by these frameworks are common, they have different models and implementation. Accordingly, the main problem is, when developing a component based application using a component framework, the design of the components becomes tightly integrated with the framework implementation and the framework model is embedded in the component functionality, and hence reduces reusability. Another problem arose is, the designers must have in-depth knowledge of the implementation of a component framework to be able to model, design and implement the components and take advantages of the services provided. To address these problems, this research proposes the Attribute based Component Design (AbCD) approach which allows developers to model software using logical and abstract components at the specification level. The components encapsulate the provided functionality, as well as the required services, runtime requirements and interaction models using a set of attributes. These attributes are systemically derived by grouping common features and services from light weight component frameworks and heavy weight component frameworks that are available in the literature. The AbCD approach consists of the AbCD Meta-model, which is an extension of the บML meta-model, and the Component Design Guidelines (CDG) that includes core Component based Software Engineering principles to assist the modelling process for designers. To support the AbCD approach, an implementation has been developed as a set of plug-ins, called the AbCD tool suite, for Eclipse IDE. An evaluation of the AbCD approach is conducted by using the tool suite with two case studies. The first case study focuses on abstraction achieved by the AbCD approach and the second focuses on reusability of the components. The evaluation shows that the artefacts produced using the approach provide an alternative architectural view to the design and help to re-factor the design based on aspects. At the same time the evaluation process identified possible improvements in the AbCD meta-model and the tool suite constructed. This research provides a non-invasive approach for designing component based software using model driven development

A design recording framework to facilitate knowledge sharing in collaborative software engineering

This paper describes an environment that allows a development team to share knowledge about software artefacts by recording decisions and rationales as well as supporting the team in formulating and maintaining design constraints. It explores the use of multi-dimensional design spaces for capturing various issues arising during development and presenting this meta-information using a network of views. It describes a framework to underlie the collaborative environment and shows the supporting architecture and its implementation. It addresses how the artefacts and their meta-information are captured in a non-invasive way and shows how an artefact repository is embedded to store and manage the artefacts

Policy Outcomes in Indonesia Before and After Democratization

Different types of regimes face different political situations and have different incentives to pursue different policies. In this paper, I am examining whether there are any differences in economic and social policy outcomes under democracy and dictatorship in Indonesia. The study is divided into two periods. The first period covers the authoritarian rule of President Suharto(1966 to 1998) and the second period covers the new democratic government(1999 to 2010). I set out by analyzing the rules used in distinguishing democracy from dictatorship and discussing the process by which Suharto\u27s regime was categorized as a dictatorship and the Indonesian government after 1999 as democratic. Then I compare and contrast the economic and social policies pursued under each of the two regime types and the policy outcomes achieved. Some authors suggest that democracy is more conducive to economic and human development than authoritarian leadership whereas others suggest that there is no significant difference. Some even suggest the authoritarian regime to be better at developing a country. In the case of Indonesia, I found that there is no significant change in the trend both in economic and human development and in some cases, the development rate is slower under democracy. I discuss the findings in light of literatures on democracy and development. Indonesia\u27s democracy is still young and the democratic period covered by the study is relatively short compared to the authoritarian period. Better comparison of policy outcomes could be made in the future if further research can be done after Indonesia\u27s democracy becomes stronger

Towards collaborative learning via shared artefacts over the Grid

The Web is the most pervasive collaborative technology in widespread use today; and its use to support eLearning has been highly successful. There are many web-based Virtual Learning Environments such as WebCT, FirstClass, and BlackBoard as well as associated web-based Managed Learning Environments. In the future, the Grid promises to provide an extremely powerful infrastructure allowing both learners and teachers to collaborate in various learning contexts and to share learning materials, learning processes, learning systems, and experiences. This position paper addresses the role of support for sharing artefacts in distributed systems such as the Grid. An analogy is made between collaborative software development and collaborative learning with the goal of gaining insights into the requisite support for artefact sharing within the eLearning community

Support for collaborative component-based software engineering

Collaborative system composition during design has been poorly supported by traditional CASE tools (which have usually concentrated on supporting individual projects) and almost exclusively focused on static composition. Little support for maintaining large distributed collections of heterogeneous software components across a number of projects has been developed. The CoDEEDS project addresses the collaborative determination, elaboration, and evolution of design spaces that describe both static and dynamic compositions of software components from sources such as component libraries, software service directories, and reuse repositories. The GENESIS project has focussed, in the development of OSCAR, on the creation and maintenance of large software artefact repositories. The most recent extensions are explicitly addressing the provision of cross-project global views of large software collections and historical views of individual artefacts within a collection. The long-term benefits of such support can only be realised if OSCAR and CoDEEDS are widely adopted and steps to facilitate this are described. This book continues to provide a forum, which a recent book, Software Evolution with UML and XML, started, where expert insights are presented on the subject. In that book, initial efforts were made to link together three current phenomena: software evolution, UML, and XML. In this book, focus will be on the practical side of linking them, that is, how UML and XML and their related methods/tools can assist software evolution in practice. Considering that nowadays software starts evolving before it is delivered, an apparent feature for software evolution is that it happens over all stages and over all aspects. Therefore, all possible techniques should be explored. This book explores techniques based on UML/XML and a combination of them with other techniques (i.e., over all techniques from theory to tools). Software evolution happens at all stages. Chapters in this book describe that software evolution issues present at stages of software architecturing, modeling/specifying, assessing, coding, validating, design recovering, program understanding, and reusing. Software evolution happens in all aspects. Chapters in this book illustrate that software evolution issues are involved in Web application, embedded system, software repository, component-based development, object model, development environment, software metrics, UML use case diagram, system model, Legacy system, safety critical system, user interface, software reuse, evolution management, and variability modeling. Software evolution needs to be facilitated with all possible techniques. Chapters in this book demonstrate techniques, such as formal methods, program transformation, empirical study, tool development, standardisation, visualisation, to control system changes to meet organisational and business objectives in a cost-effective way. On the journey of the grand challenge posed by software evolution, the journey that we have to make, the contributory authors of this book have already made further advances

the case of oil and gas companies

Thesis(Master) --KDI School:Master of Public Policy,2016This study aims to learn the foreign investors’ perception of FDI investment climate in and explore the major influencing factors for their investment decisions and their social contribution in the case of oil and gas companies operating in Myanmar. Primary data is collected from Foreign Investor Perception Survey and key informant interview with different stakeholders. Based on this survey, the study found that the foreign investors’ retrospective and prospective views on FDI climate is magnificent while the New Myanmar Investment Law (2016) become the main factor in promoting FDI. Concerned with the principal drivers of investment decision, resource availability is the most important factor, and the cost of production, the rule of law, and stable policy environment and political commitments are major influencing factors. The tax incentive is not the major driver for their investment decision even though the government is offering generous tax incentives. In examining the influencing factors of social contribution, almost all of the respondents are very keen to contribute human capital development programs and willingness to deal with local governments. Community support from the project area is also a major factor driving factor. Hence, the study suggests creating the dialogue channels with foreign companies and a better understanding of the government’s policies. Besides, the study also recommends to build the capacity of the civil servants, to strengthen the state/region governments’ capability to administer foreign investment projects and to enforce social contribution programs through the PSC obligation or MIC and reviewing tax expenditure when giving generous tax incentives and incorporating tax expenditure report in the budget preparation.Chapter I:Introduction Chapter II: Methodology Chapter III: Findings and Discussion Chapter IV: ConclusionmasterpublishedAung Phyo KYAW
