Exploring academic teachers’ continuance toward the web-based learning system: The role of causal attributions

The Expectation Confirmation Model (ECM) is a popular model used to explain the continuance of information system usage. However, past studies have found that the ECM, based on extrinsic motivations (e.g. perceived usefulness, user satisfaction), has limitations insofar as people often have both intrinsic and extrinsic motivations simultaneously. This study used the belief of causal attributions to extend the ECM and verify it in a web-based learning system (WLS) context. Nine hypotheses were derived from the modified ECM. Empirical data were collected by a mail survey from faculty with experience of WLS in Taiwanese universities. The final sample used for further analysis comprised of 144 respondents. The results revealed that the modified ECM has greater power to explain the continued intention of WLS usage even if the effects of user satisfaction and perceived usefulness on continued intention are reduced.     

Beyond the Web: Mobile WAP-Based Management

Mobility, tightening competition and changes in system administrator behavior present new challenges in the management world. In particular, the need to constantly monitor services and rapidly identify and fix problems is becoming increasingly important. The Internet has made it possible to offer a comprehensive range of management services and applications accessible over the web. Nevertheless, in the near future a new and improved way to manage systems will be done by means of mobile phones. This paper shows how existing web-based solutions can be enhanced to support the new generation of media phones based on WAP (Wireless Application Protocol) technology. Although the specific focus of this work is on management solutions, the rsults are general and applicable to many other types of existing web-based applications. Some implementation details and experiences drawn from adding a WAP interface to an existing web-based management application are described.     

Design and implementation of a web-based medical drawing management system

This paper addresses the architecture and implementation of a medical drawing management system. The system enables physicians to draw directly on a patient picture or built-in anatomical templates of a body part. It contains modules for querying patient data and managing associated drawings including sketching, uploading, and sharing features. The system adapts to embed Windows-based applications into web pages; the web-based applications contain Windows-based graphical tools and enable seamlessly incorporating necessary drawing modules into the web-based healthcare information system at National Taiwan University Hospital. The system provides a web-based sketching capability that effectively support practitioners’ daily operations, as well as the use of paperless, digitizing patient records, and ultimately, will improve the overall quality of healthcare.     

Reviewing Enterprise Content Management: a functional framework

Enterprise Content Management (ECM) focuses on managing all types of content being used in organizations. It is a convergence of previous approaches that focus on managing only particular types of content, as for example documents or web pages. In this paper, we present an overview of previous research by categorizing the existing literature. We show that scientific literature on ECM is limited and there is no consensus on the definition of ECM. Therefore, the literature review surfaced several ECM definitions that we merge into a more consistent and comprehensive definition of ECM. The Functional ECM Framework (FEF) provides an overview of the potential functionalities of ECM systems (ECMSs). We apply the FEF in three case studies. The FEF can serve to communicate about ECMSs, to understand them and to direct future research. It can also be the basis for a more formal reference architecture and it can be used as an assessment tool by practitioners for comparing the functionalities provided by existing ECMSs.

A web-based learning and assessment system to support flexible education

Abstract At a time where increased costs and resource constraints are experienced by many tertiary institutions globally, the pressure to find alternative methods to deliver teaching and assessment increases. Whilst the individual learning experience is paramount, the need to manage the numbers, resources and assessment provide an administrative overhead and headache to all teaching staff. With this predicament in mind a computer-supported learning system ( CECIL ) was developed. It is a web-based teaching and learning resource and administration system. This paper describes the CECIL structure and discusses the potential benefits that a university-wide resource management system may have in terms of the educational flexibility and resource sharing.     

Intervention and strategy analysis for web group-learning

Abstract Owing to the lack of face-to-face interactions, students using a web-based learning system are likely to study alone and with relatively little classmate support and pressure. Teachers in a web-based learning system may apply a group-learning model to overcome this problem. Teachers first need to organise, manage and monitor the group learning and they must take appropriate actions based on teaching strategies to improve the learning achievements of the students. To perform these tasks effectively, teachers must obtain relevant information by analysing the huge volume of web-access logs or by monitoring web interactions. This paper presents novel methodologies for developing instruments to assist teachers in performing intervention and strategy analysis. The proposed methodologies apply data mining tools provided by existing database management systems. Database techniques, including the multi-dimensional cube, are then applied to make student web logs meaningful and helpful to teachers in managing group learning. The associate rule mining tool is finally employed to assist teachers in analysing their pedagogical strategies. These tools relieve teachers of tedious data collection and analysis, allowing them to focus on managing the groups to promote students' learning achievement.

A new framework for managing IT-enabled business change

Abstract. Although information systems and technology (IS/IT) investments have always caused varying degrees of business change, the main purpose of many of today's IS/IT implementations is to change the business and/or organization in some significant way. However, most organizations' approaches to managing IS/IT developments have changed little in the last 15–20 years and are heavily dependent on methodologies of IS/IT development and associated project management principles. The philosophy being adopted by many organizations today is that there are few IS/IT projects (some infrastructure investments only) that do not cause business changes and therefore they are really 'business projects involving IS/IT'. This exploratory research set out to devise a new framework for 'IT and change' management, which is more appropriate to today's realities than traditional approaches. The initial framework was derived from 'first principles', then adapted and further developed by applying and testing it in a range of real projects in organizations. This paper summarizes the results of that work.

Autonomic QoS control in enterprise Grid environments using online simulation

As Grid Computing increasingly enters the commercial domain, performance and quality of service (QoS) issues are becoming a major concern. The inherent complexity, heterogeneity and dynamics of Grid computing environments pose some challenges in managing their capacity to ensure that QoS requirements are continuously met. In this paper, a comprehensive framework for autonomic QoS control in enterprise Grid environments using online simulation is proposed. This paper presents a novel methodology for designing autonomic QoS-aware resource managers that have the capability to predict the performance of the Grid components they manage and allocate resources in such a way that service level agreements are honored. Support for advanced features such as autonomic workload characterization on-the-fly, dynamic deployment of Grid servers on demand, as well as dynamic system reconfiguration after a server failure is provided. The goal is to make the Grid middleware self-configurable and adaptable to changes in the system environment and workload. The approach is subjected to an extensive experimental evaluation in the context of a real-world Grid environment and its effectiveness, practicality and performance are demonstrated.

Managing Problems for Global Software Production – Experience and Lessons

With the increase in size and complexity of current software projects, many large companies have established global software production lines over the world to develop and deliver software products with collaborative software development processes involving multiple teams located at different sites. Supporting global software production needs an effective software-engineering environment to meet the special requirements of the collaborative software development process, diverse management methods and engineering practice. WWW technology provides powerful means to set up an enterprise-oriented software engineering environment for global software production due to its advantages in networking, global access, internationalization, and communication. Although there are many articles addressing the methods and experience in building web-based applications systems and tools, very few papers discuss the real-world problems and solutions in the development and deployment of web-based software tools to support a collaborative software development process for global software production. This paper discusses the real world issues, and reports our experience and lessons in building and deploying a web-based problem information management system (PIMS) to support global software development processes at Fujitsu. It focuses on the real issues and needs of current collaborative development process involving multiple teams, and highlights the benefits and impact of the PIMS on global software production. Moreover, it discusses our technical solutions and trade-offs in the development of PIMS, and shares our experience and lessons. Furthermore, it introduces a new data-centered conceptual process model to support diverse collaborative processes for project and problem management in global software production. Finally, the paper shares our key successes and weaknesses, and reports our experience and lessons in the deployment of the system.     

Improving quality function deployment analysis with the cloud MULTIMOORA method

Quality function deployment (QFD) is a quality guarantee method extensively used in various industries, which can help enterprises shorten the product design period and enhance the manufacturing and managing work. The task of selecting important engineering characteristics (ECs) in QFD is crucial and often involves multiple customer requirements (CRs). In this paper, a modified multi‐objective optimization by ratio analysis plus the full multiplicative form (MULTIMOORA) method based on cloud model theory (called C‐MULTIMOORA) is developed to determine the ranking order of ECs in QFD. First, the linguistic assessments provided by decision makers are transformed into normal clouds and aggregated by the cloud weighted averaging operator. Then, the weights of CRs are determined based on a maximizing deviation method with incomplete weight information. Finally, the importance of ECs is obtained using the C‐MULTIMOORA method. An empirical case conducted in an electric vehicle manufacturing organization is provided together with a comparative analysis to validate the advantages of our proposed QFD model.

Developing a web-based system for supervised classification of remote sensing images

Web-based image classification systems aim to provide users with an easy access to image classification function. The existing work mainly focuses on web-based unsupervised classification systems. This paper proposes a web-based supervised classification system framework which includes three modules: client, servlet and service. It comprehensively describes how to combine the procedures of supervised classification into the development of a web system. A series of methods are presented to realize the modules respectively. A prototype system of the framework is also implemented and a number of remote sensing (RS) images are tested on it. Experiment results show that the prototype is capable of accomplishing supervised classification of RS images on the Web. If appropriate algorithms and parameter values are used, the results of the web-based solution could be as accurate as the results of traditional desktop-based systems. This paper lays the foundation on both theoretical and practical aspects for the future development of operational web-based supervised classification systems.
