Title: Making Malaysian modern visual arts visible through MyMAOVA

Authors: Shahnim Mohd Safian

Abstract: This study was motivated by reports that indicated even though Malaysian art resources are abundant, access to these information are scattered, incomplete and not easily accessible to students, researchers and people who are less skilled in searching for information. The objective of this study are: (a) to explore the opinions of selected persons in the arts industry about their perceived usefulness of an online archive for Malaysian visual arts resources; (b) to use a matrix to compare three sets of art gallery websites; and (c) to compare the performance of the prototype archive in terms of usability and design with the three sets of art gallery websites in order to gauge the performance of the prototype. The methods used to collate data were interviews with selected art personalities and viewing selected art gallery websites to identify best practices. The Interviews confirmed the prevailing ‘disconnection’ between content existence and content provision on the web. Findings indicate positive receptivity towards a web-based repository. In developing the prototype, a set of ‘best practice’ principles was identified. A customized Attributes Evaluation Checklist based on the Olsina Web-QEM steps was used as a tool to compare the designs of several sets of art repository websites. Findings indicate that the prototype (MyMAOVA) performs well against other similar art-related websites and the digital surrogates would be able to complement original resources presently available nationally and regionally. MyMAOVA would thus afford the public, access to Malaysian art resources at both national and international levels

Title: The landscape of open access institutional repositories in the Asian continent: a 2010 census

Authors: Abrizah, A; Noorhidawati, A; Kiran, K

Abstract: This paper reports on the 2010 survey of Asian institutional repositories, highlighting the current state of the repositories and describing their characteristics in terms of types, contents, disciplines, language, technical and operational issues, and policy. It also identifies the web performance of Asian institutional repositories as reflected through global visibility and impact of the repositories; as well as the performance of the Asian top-ranked universities in the archiving and sharing their research output through institutional repositories. Data obtained from the Open Directory of Open Access Repository (OpenDOAR) and the Ranking Web of World Repositories (RWWR) were used to analyse the current state and global visibility respectively. Findings indicate that the total number of institutional repositories in Asia is 191 with Japan as the biggest contributor (38%), followed by India (19%) and Taiwan 22 (11%). Out of the 191 Asian institutional repositories identified in this study, 48 (about 23%) are listed in the Top 400 RWWR. This suggests that only 12% (48 out of 400) Asian institutional repositories are visible and incorporate good practices in their web publication as extracted from the quantitative webometrics indicators used by the ranking. Out of these 48 institutions, 29 are among the Asian Top 200 universities. However, only 14 of these 29 universities were ranked top 100 in the RWWR. The paper concludes that if the web performance of a research institution is below the expected position according to their academic excellence, university authorities should reconsider their web policy, promoting substantial increases of the volume and quality of their intellectual output / research publications through institutional repositories

Title: Open Access repositories and journals for visibility: Implications for libraries

Authors: Zainab, A.N.

Abstract: This paper describes the growth of open access repositories and journals as reported by monitoring initiatives such as ROAR (Registry of Open Access Repositories), Open DOAR (Open Directory of Open Access Repositories), DOAJ (Directory of Open Access Journals), Directory of Web Ranking of World Repositories by the Cybermetrics Laboratory in Spain and published literature. The performance of Malaysian OA repositories and journals is highlighted. The strength of OA channels in increasing visibility and citations are evidenced by research findings. It is proposed that libraries can champion OA initiatives by making university or institutional governance aware; encouraging institutional journal publishers to adopt OA platform; collaborating with research groups to jumpstart OA institutional initiatives and to embed OA awareness into user and researcher education programmes. By actively involved, libraries will be free of permission, licensing and archiving barriers usually imposed in traditional publishing situation.

Open Access to scholarly communications: Advantages, policy and advocacy

Title: Open Access to scholarly communications: Advantages, policy and advocacy

Authors: Furnival, Ariadne Chloe

Abstract: The Open Access (OA) movement regards OA modes of disseminating research as the unequivocal future of scholarly communication. Proponents of the open access movement itself have, over the last ten years, carried out systematic research to show how OA can tangibly benefit researchers, institutions and society at large. Even so, the number of research papers being uploaded to OA institutional repositories remains relatively low, frequently based on concerns which often contradict the facts. Policies for OA have been introduced to encourage author uptake, and these are also discussed here. Briefly delineating aspects of these phenomena, this paper outlines and discusses advocacy for OA in organisations, and whether this should be “downstream”, in the form of informational campaigns, or “upstream”, in the form of top-down change management. This paper seeks to make a contribution to these issues in the OA sphere, by bringing into the debate strands from the literature of the sociology of science and management science that will hopefully elucidate aspects of author reactions to OA, and the perceived changes that its adoption gives rise to.

Title: Understanding emotions to empower the Net generation

Authors: Kwon, Nahyun

Abstract: In my address, I will be talking about a pivotal need for librarians and information professionals to understand information users’ emotions to truly empower the Net Generation to educate them as informed citizens in the future. For this purpose, various characteristics of the Net generation reported in the literature will be introduced first. Subsequently, I will introduce the environment where higher education and academic libraries are situated currently, and the challenges and opportunities they are meeting now. Educators in higher education see the importance of teaching information literacy to help students prepare for their uncertain futures, and thus teaching critical thinking and critical use of information resources and services have become pivotal in the process. Yet, there are many indications that suggest many barriers for the Net Generation to access needed quality information. Among the many barriers that hamper effective information access, I will draw attention to the barriers caused by irrelevant emotions in particular, library anxiety. I will be sharing the research findings from recent studies, including my mixed-methods study of library anxiety and critical thinking dispositions among college students. These reports will demonstrate how both positive and negative emotions play a vital role throughout the information search and use process. Finally, I will share both theoretical and practical implications drawn from the empirical findings on emotions within the frameworks of affective information behavior and information literacy.

Abstract: ABSTRACT Research shows that stroke becomes the third leading cause of death in world. A lot of information provided online about stroke care is not focused on what the stroke patients really need. Furthermore, stroke patient is not the right person to gather all information about stroke care because of their limited accessibility. As a result, stroke patient did not get the correct information in their hands. The idea of this research is to insure that all the included information given through the internet is according to what the stroke people really need. This research discusses on User-Centered Design(UCD) approach, characteristics and methodologies for designing the web information system for stroke care (WISS). It uses interviews, focus group, observation, questionnaire and card sorting activities as the techniques in conducting the activities for eliciting the requirements among Malaysian users. It also discuss on eight (8) existing web-sites which offer the same information on stroke care to compare their features based on the eight (8) golden rules accordingly. This research covers four groups of users: stroke caregivers, stroke rehab centers, therapists and doctors who handle the stroke patients. Usability testing is used to evaluate the developed system for evaluation purposes. The study presents a web site as the medium to deliver the information as decided by the users. It also presents the navigation structure which is defined by user that has been iteratively design many times during evaluation process. Results of usability testing show that most of the users are satisfied with the system developed. ABSTRAK Kajian menunjukkan strok menjadi punca ketiga utama yang menyebabkan kematian di dunia.

Title: Enhancing job scheduling with adaptive prediction model based on user profiling

Authors: Chong, Sin Ni

Abstract: The recent advances in Grid and Cloud Computing have brought about a number of challenges on computing resource management. In particular, the ability to fulfil the Service Level Agreement (SLA) and Quality of Service (QoS) on job scheduling. Service providers are obliged to meet the user’s expectation that stated in the SLA. A job scheduler’s efficiency is graded based on how well the user’s expectations are met. However, the user’s Requested Time is at best an estimate and fraught with inaccuracies to begin with. This thesis focuses on developing a new runtime prediction algorithm to improve the scheduling efficiency rather than merely relying on the user’s Requested Time. In this work, an analysis on the job submission characteristics has been carried out. The result revealed that there is a trend in the job submission characteristics. An adaptive approach is used to categorize those trends into different profiles that lead to similar predictable behaviour. A novel user profile-aware method, Runtime Prediction using Dynamic Weighted Moving Average (RP-DWMA) in making runtime prediction is proposed. Based on the simulation results on 11 production workloads obtained from Grid and supercomputer, RP-DWMA has successfully improved the scheduling efficiency. The results demonstrated an average of 41.2% performance improvement with inclusive of the resubmission cost and an acceptable average error rate of about 12.4%. Furthermore, RP-DWMA is able to adapt quickly to the dynamic changes in the submission patterns with less overhead and performs well in handling user inaccuracies in runtime estimates. In conclusion, RP-DWMA is well suited for job submission environment that requires service-oriented approaches.

Title: A middleware integrating ERP, CRM and supply chain management system using service oriented architecture

Authors: Chong, Kwong Chen

Abstract: ABSTRACT In the era of competitive business world, ERP, CRM and SCM system has become among the most influential enterprise systems in term of improving competitive advantages of an organization. However, most of the systems running in companies are continue to exist in isolation. They become less relevant in today business context due to lack of integrated information achievable through each of the system respectively. This dissertation introduces an idea of service-sharing system integration approach named SCAIM that consists of a conceptual model and a connector to integrate the participated systems at conceptual level. Through the development of the conceptual model and the connector, any representational and services participated are organized in a center component and integrity these systems functionalities is mapped conceptually. Hence, the capability of SCAIM to integrate ERP, CRM and SCM is tested by using different standard testing approaches. Basically, the research methodology chosen for this dissertation is survey research; hence survey questionnaire and interview are two modes of survey research used to conduct the survey and data analysis. Of 40 survey responses, majority agreed that ERP, CRM and SCM are most suitable among the business applications to be integrated to improve competitive advantages of an organization. Moreover, this research supports the idea that SCAIM increases the integration level of ERP, CRM and SCM effectively. ABSTRAK Dalam era dunia perniagaan yang kompetitif, sistem ERP, CRM dan SCM telah menjadi antara sistem-sistem syarikat yang paling menarik perhatian dari segi meningkatkan kelebihan kompetitif bagi satu organisasi. Walau bagaimanapun, sebahagian besar sistem-sistem itu masih wujud dalam keadaan isolasi. Sistem-sistem itu menjadi kurang relevan dalam konteks perniagaan hari ini kerana kurangnya maklumat yang terintegrasi dapat dicapai melalui sistem masing-masing. Disertasi ini memperkenalkan pendekatan idea mengenai sistem integrasi perkhidmatan berkongsi bernama SCAIM yang terdiri daripada sebuah model konseptual dan penyambung untuk mengintegrasikan sistem yang menyertai di peringkat konseptual. Melalui pembangunan model konseptual dan penyambung itu, setiap representasional dan perkhidmatan yang menyertai dianjurkan dalam pusat komponen, dengan fungsi-fungsi sistem ini dipetakan dari segi konseptual. Oleh yang demikian, kemampuan SCAIM untuk mengintegrasikan ERP, CRM dan SCM diuji dengan menggunakan pelbagai pendekatan yang berbeza. Pada dasarnya, metodologi kajian yang dipilih untuk disertasi ini adalah kajian tinjauan. Maka kaji soal selidik dan wawancara adalah dua mod kajian tinjauan yang digunakan untuk mejalankan kajian dan data analisis. Daripada 40 tanggapan tinjauan, majoritinya bersetuju bahawa ERP, CRM dan SCM yang paling sesuai di antara aplikasi perniagaan yang dapat diintegrasikan untuk meningkatkan kelebihan kompetitif suatu organisasi. Selain itu, kajian ini menyokong idea bahawa SCAIM meningkatkan tahap integrasi ERP, CRM dan SCM dengan berkesan.

Title: Rapid application development toolkit for persistence framework-based web application development

Authors: Choo, Choon How

Abstract: Abstract Software systems must be delivered quickly in order to respond to today’s rapid changing business environments. In response to this, Rapid Application Development (RAD) based on persistence framework has been identified and adopted in this research as an approach to develop a method of designing web applications so that the whole process is quick, painless, and nearly effortless. The main objective of the research is to propose an approach to develop a toolkit to support rapid web application development leveraging on a persistence framework. The persistence framework was introduced to overcome the problem of object-relational impedance mismatch occurred in most applications that need access to a relational database. However, most persistence frameworks are difficult to configure and use, thus do not really contribute much to the improvement of software developers’ overall productivity. This research proposes suitable concepts, architecture, design and development of a rapid application development toolkit that will leverage on a persistence framework with configuration wizard to subsequently provide an easy-to-use and customisable front-end web application development environment for developers to perform rapid web application development. Unlike prior efforts, the combination of the features of rapid prototyping, code generation and configuration wizard on top of the persistence framework provided by the proposed RAD toolkit enables developers not only to deliver web applications within a shorter time frame through an easy-to-use front-end environment, but also achieve encapsulation of database access from business objects. The research was designed and implemented using Java programming language. An evaluation process carried out shows the effectiveness of the approach that makes exploration of future works possible. Abstract (in Malay Language) Sistem perisian harus dibangunkan dengan cepat untuk menyelaraskan persekitaran perniagaan yang sentiasa berubah pada masa ini. Sehubungan dengan itu, Pembangunan Aplikasi Pantas (RAD – Rapid Application Development) yang berdasarkan persistence framework (kerangka yang menguruskan penyimpanan data) telah dikenal pasti dan diterima pakai dalam kajian ini sebagai pendekatan untuk menghasilkan satu kaedah mereka bentuk aplikasi web supaya seluruh prosesnya adalah cepat dan mudah. Objektif utama kajian ini adalah untuk mencadangkan satu pendekatan untuk membangunkan satu set alat (toolkit) untuk menyokong pembangunan aplikasi web pantas yang bergantung pada persistence framework. Sebenarnya, persistence framework diperkenalkan untuk mengatasi masalah object-relational impedance mismatch (ketidaksamaan antara teknologi berorientasikan objek dengan konsep hubungan) yang banyak berlaku pada aplikasi yang memerlukan akses pangkalan data jenis hubungan (relational database). Namun demikian, kebanyakan persistence framework sukar untuk dikendalikan sehingga tidak begitu banyak menyumbang kepada peningkatan produktiviti pembangun perisian. Kajian ini mencadangkan konsep, seni bina, reka bentuk dan pembangunan set alat pembangunan aplikasi pantas (RAD toolkit) yang akan memanfaatkan persistence framework dengan adanya program kecil (wizard) konfigurasi, kemudian ia menyediakan persekitaran pembangunan aplikasi web yang mudah dikendalikan kepada pembangun perisian untuk melakukan pembangunan aplikasi web pantas. Tidak seperti dahulu, kombinasi ciri-ciri pembinaan prototaip cepat (rapid prototyping), penjanaan kod pengaturcaraan (code generation) dan program kecil konfigurasi bagi persistence framework yang disediakan oleh RAD toolkit membolehkan pembangun perisian tidak hanya menghasilkan aplikasi web dalam jangka masa yang lebih pendek melalui penggunaan muka depan persekitaran yang mudah dikendalikan, tetapi juga dapat mengurungkan akses pangkalan data dari objek bisnes. Kajian ini telah direka dan dilaksanakan dengan menggunakan bahasa pengaturcaraan Java. Proses penilaian telah dijalankan untuk menunjukkan keberkesanan pendekatan ini dan ia juga sebagai eksplorasi untuk kajian masa depan.
