  • Citizen centric assessment framework for e-Governance services quality   Order a copy of this article
    by Vinay Singh, Garima Singh 
    Abstract: Citizen-centric e-governance services are essential to enhance the quality of life of citizens while ensuring citizen empowerment. The present study proposes a framework of assessing quality of e-governance services from citizens perspective to find out the degree of its quality impacting citizen satisfaction. The framework is validated through primary data collected from 213 respondents. Confirmatory factor analysis and structured equation modelling are employed to validate the model. The results depict quality of e-governance service and the information being disseminated to the citizens impact on their satisfaction significantly. The study contributes a parsimonious model that can significantly contribute in future theoretical advances in e-governance quality assessment. The findings can bridge the gap between government initiatives and citizens' needs. Thus designing high quality e-governance services while keeping the needs and expectations of citizen in focus translates its functional efficacy.

  • Code Refactoring Using Slice-Based Cohesion Metrics and Aspect-Oriented Programming   Order a copy of this article
    by Jagannath Singh, P.M. Khilar, D.P. Mohapatra 
    Abstract: Software restructuring is essential for maintaining software quality. It is a usual practice that we first design the software and then go for coding. After coding, if there is any change in the requirement or if the output is incorrect, then we have to modify the code again. For each small code modification, it is not feasible to alter the design. These minor changes made to the code causes decay in the software design. Software refactoring is used to restructure the code to improve the design and quality of the software. In this paper, we propose an approach for performing code refactoring. We use slice-based cohesion metrics to identify the target methods that require refactoring. After identifying the target methods, we use program slicing to divide the target method into two parts. Finally, we use the concept of Aspects to alter the code structure in a manner that does not change the external behavior of the original module.

  • A TRIANGULAR PERCEPTION OF SCOPE CREEP INFLUENCING THE PROJECT SUCCESS   Order a copy of this article
    by Lakshmi Madhuri, Suma V, Uma Mohan Mokashi 
    Abstract: Project management strategies are a part of every organization as developing high quality customer satisfied software is always one of the challenges for any software organization. Though, the scope creep is known to be one of the factors which influences project success, existing project management strategies do not effectively measure or predict the scope creep. This paper focuses on effective scope creep management which is achievable through a comprehensive analysis of the scope creep and its impact on project success. The paper further presents a case study conducted in one of the leading software companies to investigate the significance and impact of scope creep in the project success. An investigation was carried out on several empirical projects and a three dimensional visualization of scope creep on success of project was brought out. This trio visualization comprises of historical data perspective which leads to visualize the inferences in a pictorial representation perspective. Facts, thus, gained from historical and pictorial data perspectives lead one towards visualization of scope creep and its management using a mathematical modeling perspective. This mode of visualizing the scope creep and its implications on project success ensures one to effectively modulate their strategies in order to develop software products which attain total customer satisfaction.

  • An Empirical Examination of Antecedents Determining Students Usage of Clickers in a Digital Marketing Module   Order a copy of this article
    by Nripendra P. Rana, Yogesh K. Dwivedi 
    Abstract: As more and more educational institutions are integrating new technology such as clickers into their learning system, it becomes increasingly essential to have an understanding of students perceptions about such technology on their overall learning process. The incorporation of clickers into teaching instructions has created implications for teaching practices and student satisfaction. The purpose of this research is to understand student use and satisfaction with clickers in a large undergraduate digital marketing class in a British university. To do so, we propose a conceptual model based on information systems (IS) success models to understand students usage behavior and satisfaction with clickers. The data were analysed based on 138 valid responses gathered from the students, where clickers are effectively used for teaching and learning purposes. The results provided a strong support for all eight hypothesised relationships and adequate variance on its key dependent variables in the proposed research model.

  • Relative Importance of CSF in ERP Implementation Strategy: A Multi-Participant AHP Approach   Order a copy of this article
    by Shruti Nagpal, Ashok Kumar, Sunil Kumar Khatri 
    Abstract: Enterprise Resource Planning Systems (ERP) have found a wide acceptability among organizations, albeit with a pinch of salt. ERP systems appropriately bring about uniformity in the software across the organization by bringing all the processes under one umbrella. But the low adoption rates and greater time to value are often reasons for low ERP implementation success rates and even ERP implementation failures. Researchers have chronicled various Critical Success Factors (CSF) that determine a successful ERP implementation. This paper utilizes multi-participant Analytic Hierarchy Process (AHP) to determine the relative importance of CSF in various ERP implementation strategies. The paper contributes to the existing knowledge of CSF in ERP implementations by showcasing that CSF have varying importance across ERP implementation strategies.

  • Emergence of Multipresence A theoretical underpinning   Order a copy of this article
    by Somesh Gaur, Bala Krishnamoorthy 
    Abstract: Anytime anywhere and immersive Information and Communication technologies have penetrated all spheres of our life. Because of these technologies, an individual can be present in multiple environments either real or virtual at a given time or in a time frame. Such technology driven Multipresence has emerged as a prominent behavioral phenomenon today. Multipresence might have significant influence on an individuals behavior as well as on team, organization and society. Despite being such a prevalent and important behavioral phenomenon, there has been limited research and literature in this area. In this conceptual paper, we explore and refine the concept of Multipresence. We start with the exploration of concept of Presence, which forms the basis for understanding Multipresence. We further discuss various aspects of Multipresence from the literature. We also introduce a new revised definition and new concepts about Multipresence. Finally, we discuss possible implications of such behavior on performance of an individual and suggest potential future research opportunities in this area.

  • ERP Implementation in University: A Case Study in Thailand   Order a copy of this article
    by Nacha Chondamrongkul 
    Abstract: Enterprise Resource Planning (ERP) is considered a proven solution that enhances the organizations structure, which results in better productivity. Nowadays, universities have many reasons to improve efficiency in administrative operations. Therefore, there are number of universities that aim to enhance administrative efficiency by implementing ERP system. However ERP system implementation in the university has a high failure rate because of its unique characteristic. Even though a number of critical success factors have been proposed but there is rare example of how to put them into practice. This paper presents a case study in a Thai university that implements ERP system, which shows how selected critical success factors are taken into practice throughout implementation process. A combination of semi-structured interviews and survey questionnaires are used as research methods to observe and analyze implementation process in the university environment. The study shows software learnability as a significant challenge that causes problems in the post-implementation phase. Also, the study highlights ERP system as the foundation for the development of forthcoming IT system.

    by Bhim Sain Singla, Himanshu Aggarwal 
    Abstract: To-day, with the advent of Web technologies, there has been a sea change in the business scenario of not only the commercial organizations but also the higher education institutions. The organizational goals can be achieved more easily and efficiently by reaching out to a vast population through this medium. The educational institutes can provide quick and reliable services to the stakeholders of these websites within the shortest span of time and limited financial resources. However, the benefits to be derived from such websites rest more on their content quality in accordance with the requirements and expectations of the end users. Thus, this study is a modest attempt to evaluate the content quality of Indian universities websites through the perspectives of end users based on their demographic variables such as gender, age, education and status. The study is based on primary data which has been collected through a well-structured and pre-tested questionnaire from the respondents. The findings are extremely significant for the Indian universities as the improved quality of their websites would help them to attract more and more number of students for admission, and in improving their ranking.

  • Data Mules Oriented Particle Swarm Optimization Based Mobile Sink Data Gathering Techniques with Analytical Data Analysis using Linear Regression   Order a copy of this article
    by Govindarajan Saravanan, MJS Rangachar 
    Abstract: Wireless sensor networks with convergecast nature poses great challenge on data collection strategies. In order to cut down the issues on constrained resources of wireless nodes, here a sink based (PSOMSDG) Particle Swarm Optimization Based Mobile Sink Data Gathering had been proposed. This PSOMSDG is a rendezvous based protocol which uses three metrics for data gathering based on the nodes position as; when the nodes are in inertia; when they change to optimistic position (based on current scenario); finally when they change to swarms optimistic position. These three metrics avoid long detour path by providing global optimal length constrained trajectory. In addition, residual energy consumption of protocol was achieved in a balanced manner. The performance is noticed with increasing data rates and compared with Biased Sink Mobility with Adaptive Stop Times (BSMAST). Then data obtained with NS2 simulation which was developed into a linear regression model. Finally the analytical study states that there is a strong relationship between data rate and energy consumption. The Analysis Of Variance (ANOVA) based analysis shows that there is a strong influence between groups.

    Abstract: Abstract: Knowledge sharing has been receiving the highest concern among knowledge management processes. It does attract many studies due to its vital role in the success of organizations. In fact, the practice of knowledge sharing in an organization is influenced by employees intention for sharing knowledge. This paper aims to investigate the influence of two technological factors precisely knowledge sharing systems and web2.0 on the individuals intention for knowledge sharing. Likewise, this paper examines the impact of knowledge sharing intention on the practice of knowledge sharing in organizations, particularly in oil and gas industry. Based on these objectives, a model was proposed, and research hypotheses were developed accordingly. Data were collected from seven international petroleum companies using a survey method. In details, an online questionnaire was used as a survey instrument which yielded a sample size of 157. Measurements were verified through reliability analysis using Cronbachs alpha method. Furthermore, factor analysis was also conducted for the purpose of dimension reduction and detecting any complex structure among the model variables. Further statistical tests were completed including correlation and multicollinearity tests. Structural equation modeling approach was used to evaluate the research model and test the proposed hypotheses as well. The findings indicated that both knowledge sharing systems and web2.0 platform positively influence knowledge sharing intention. Moreover, it was found that the intention to share knowledge has a positive influence on the knowledge sharing practice within organizations. All three proposed hypotheses were significantly supported. Finally, an extension of the study was suggested to be considered in the future.

  • New Local Sedec Pattern(LScP) Descriptor for improving the retrieval efficiency in Content Based Image Retrieval   Order a copy of this article
    by Umamaheswaran Subashchandrabose, Suresh Kumar N., Ganesh K 
    Abstract: In this paper, a novel Content Based Image Retrieval (CBIR) method is proposed using the Local Sedec Pattern(LScP). The Local Binary Pattern (LBP) and the Local Ternary Pattern (LTP), encode the relationship between the referenced pixel and its surrounding pixels, by computing gray-level difference, but in a different way. The proposed methods encode the relationship between the center pixel and its neighbors, based on directions such as vertical, horizontal and diagonal. Calculation based on First Order Derivatives is used here. Second order derivative is also applied to obtain LScP. The performance of the proposed method is compared with the LTrP and other local pattern (LBP,LDP and LTP)which results are obtained using benchmark image databases viz., Corel 1000 database(DB1), Brodatz texture database(DB2). Performance of the LScP shows improvement in retrieval from 75.9%/48.7% to 86.52%/54.4% in DB1, for average precision/average recall as compared with LTrP and other local patterns . A similar comparison shows improvement from 85.30% to 91.5% in terms of average retrieval rate on database DB2

    by Emmanuel C. Ogu, Benita Amos, Uduakobong Edy-Ewoh 
    Abstract: Cognizant Computing is one of the emerging, current and rapidly evolving information technologies that portends great promises for savvy businesses of the 21st century, with the potential to create huge savings and returns for businesses by reducing overhead costs and expenses. Lean practices in the business manufacturing and process industries have been proven to also guarantee global competitiveness and enhance efficiency of the manufacturing and process chain operations of businesses, while ensuring enhanced financial performance, productivity and market performance of end products. Until now, the existing nexus between these twain paradigms have remained blurred, with very little knowledge of how both can be combined and harnessed to ensure business success in the 21st century. As the world advanced towards the dawn of the long-deliberated Industry 4.0 revolution, it has become necessary that these twain concepts be re-investigated with a view to uncover a possible nexus between them; which, upon implementation, could guarantee the success, competitive advantage and stability of businesses in the coming industrial revolution. This study utilizes the exploratory research methodology due to the relatively new and emergent nature of the domain of discourse. The study introduces cognizant computing and illuminates its prospects for businesses in the present era, and how lean practices could combine with cognizant computing to guarantee the success and sustainability of businesses in the coming industrial age.

    by Vinay Singh, Anurag Singh, Divya Jain, Vimal Kumar, Pratima Verma 
    Abstract: With invent of Web 2.0 technology, online interpersonal interaction has been turned into the sensation of twentieth century. Websites and other applications on the Internet provide large amounts of data and new research area to the researchers. Twitter is one of them. Structurally, this site is the complex network of users connected to each other whose nodes represent individuals or organizations, and links mimic the interactions among them. Understanding the graph is critical, both to enhance current frameworks and to plan new applications for this platform. Here, we will endeavor to study the mixing patterns possible in Twitter online social networking site due to the geographic locations mentioned by the user via measuring assortativity coefficient and find out how these patterns are affecting the structural properties of the network. We examined data gathered from Twitter online social network by crawling on this site using the open Application Programming Interface (API)available for us by Twitter. We obtained a small portion of this social networks graph and observed that assortativity is indeed present in this network and also when we ranked the user according to their followers count and then remove few of them from the dataset, we found that network is resilient to the deletion of highest degree nodes and assortativity still exists. We performed the same experiment with random users and found the same results. To validate the above property observed in this social network, we plotted the graph to show the presence of core components in the network.

  • Evaluation of the StrAli-BPM approach: Strategic alignment with BPM using agreements in different levels   Order a copy of this article
    by Guilherme Salles, Vitor Barros, Marcelo Fantinato, João Albuquerque 
    Abstract: The strategic alignment between business areas and Information Technology (IT) is motivated by the needs of large organizations to thoroughly use the potentials of IT to transform business processes and deliver good products and services. In the treatment of processes and services, it is important to attend also to non-functional requirements, minimizing misapplied IT investments due to inefficiency. However, business process modelling languages do not represent these requirements, focusing only on functional requirements. Thus, in order to fill this gap, this paper presents the StrAli-BPM (Strategic Alignment with BPM) approach, which is divided in two parts BLA@BPMN and BLA2SLA: the former to extend the BPMN language aiming to embody non-functional requirements, in the form of BLAs (Business Level Agreements) enriched with KPIs (Key Performance Indicators); and the latter to semi-automatically derive a set of SLAs (Service Level Agreements), associated with web services, from a pre-defined BLA. This paper mainly describes the results obtained with the evaluation of the StrAli-BPM approach. First, the approach was evaluated by a proof of concept, based on the developed prototype tools, which allowed to verify its technical applicability. Then, a survey experiment was conducted with a panel of experts, members of a real organization. As a result, the proposed approach was well accepted by the experts who judged it as important and necessary to cover a gap in the BPM field. Some lessons learned from both evaluations are presented.

  • Factors driving consumer loyalty intention towards e-tailers: an integrated model   Order a copy of this article
    by Plavini Punyatoya, Anurag Satpathy, Arjun Agrawal 
    Abstract: Online shopping has emerged as one of the most important e-commerce applications in recent years. However, there is limited empirical research which has examined factors driving Indian consumers loyalty intention towards e-tailers. Thus, this study proposed and tested a model that examines the effect of perceived website quality, security and privacy policy, shared value, and perceived e-tailer reputation on online consumers trust, perceived risk, satisfaction, and loyalty intention in India. Data were collected from Indian online consumers and analysed using structural equation modelling. The results showed that perceived website quality has a strong positive effect on customer satisfaction. Data further demonstrate that security and privacy policy, and perceived e-tailer reputation directly influence e-trust. Online shoppers previous satisfaction with an e-tailer also builds e-trust and thus, decreases perceived risk. When a consumer is more satisfied with an e-tailer and has stronger trust on the same, this will lead to higher loyalty intention towards the e-tailer. These findings have interesting implications for website designers and online retailers. Finally, we discuss some limitations of our study and directions for future research.
    Keywords: e-tailer; perceived website quality; security and privacy policy; shared value; perceived e-tailer reputation; customer satisfaction; e-trust; perceived risk; customer loyalty intention; India

  • Sequence Clustering Approach for clustering Web User sessions   Order a copy of this article
    by Pradeep Kumar 
    Abstract: Clustering web usage data is useful to discover interesting patterns pertaining to user traversals, behavior and their usage characteristics. It is also useful for trend discovery as well as for building personalization and recommendation engines. Since web is dynamic, clustering web user transactions results in arbitrary shapes. Moreover, users accesses web pages in an order in which they are interested and hence incorporating sequence nature of their usage is crucial for clustering web transactions. In this paper, we present an approach to cluster web usage sequence data and removing noise using DBSCAN algorithm. We also study the impact of clustering process when both sequence and content information is incorporated while computing similarity measure. We use S3M (Sequence and Set Similarity) measure to capture both the order of occurrence of page visits and the page information itself, and compared the results with Euclidean distance and Jaccard similarity measures. The Inter-cluster and Intra-cluster distances are computed using Average Levensthein distance (ALD) to demonstrate the usefulness of the proposed approach in the context of web usage mining.

  • MULTI TERM BASED CO-TERM FREQUENCY METHOD FOR TERM WEIGHTING IN INFORMATION RETRIEVAL   Order a copy of this article
    by Santhanakumar Markandeyan, Christopher Columbus Chinnappan, Jayapriya Kalyanakumar 
    Abstract: Now a day, World Wide Web (WWW) has become the only source of all kind of information. Retrieving the relevant web pages based on user queries from WWW is an exigent task. Term Frequency Inverse Document Frequency (TF-IDF) is the most frequently used method for term weighting based on the occurrences and presence of a term inside the document. Retrieved document based on a single query term may not relate to the user search. This may lead the user to process the unwanted information. So, this paper proposes a new term weighting method named Co-Term Frequency, in which the weight is assigned according to the multi terms commonly occur in all documents. From the measures of precision, recall and F-score of the proposed method, it is clearly evident that the proposed framework retrieves the most relevant web pages when compared to other term weighting methods.

  • The impact of the quality of the service from IS/IT departments on the improvement of operational performance: The point of view of users of technological innovations   Order a copy of this article
    by Ricardo Santa, Mario Ferrer, Liliyana Makarova Jørsfeldt, Annibal Scavarda 
    Abstract: The purpose of this article is to examine how the provision of services from Information Systems / Information Technology (IS/IT) departments helps organisations to achieve reliable operations and improvements in operational performance in the view of the users. A Structural Equation Modeling (SEM) was used to examine structural relationships between the set of observed variables and the set of continuous latent variables from responses of a sample of 138 individuals from large service organisations in Australia that had recently implemented Enterprise Information Systems (EIS). The results suggest that there is no direct influence of the quality of the service from IS/IT departments on the improvement of operational performance, but there is an indirect relationship through the achievement of operational effectiveness. The findings also suggest that focusing solely on the effectiveness of the technological innovation is detrimental to long-term operational benefits.

    by Mahmoud Migdadi, AbdelRaouf Dado, Othman Al Safadi, Hisham Shadid 
    Abstract: With the increase in population and economic development of modern society of world, more and more people have cars of their own. The result is that traffic jam is more often than ever before. What is worse, in the increasingly crowded cities is the possibility of not finding safe parking lot especially in such crowded areas which could be a frustrating experiment. As parking facilities grow large, drivers need advanced methods of parking to reduce inefficiencies in finding spaces. A solution to reduce the drivers searching time for vacant car-park lots will greatly save time, reduce cost and improve the traffic flow in the car park areas. To this end, the researchers has created a web-based application (including PHP and MySQl server) which aims at providing its users (the drivers) several benefits-when they utilize it- such as provide real-time parking spot availability information in order to book a safe parking space any time and from any place, save them time and efforts, subscribe and pay electronically. In addition, the system allows parking owners and/or mangers to manage their own parking spaces bookings and subscriptions more efficiently.

  • Preventing Business And Information Technology Misalignment When Introducing Technology Changes   Order a copy of this article
    by Oscar Avila, Kelly Garcés 
    Abstract: Organisations introduce changes in order to adapt themselves to the extremely changing context. These changes often impact Information Technology (IT) and Business domains. In most of the cases, the scope of the organisational elements in these domains requiring adaptation is not well defined, leaving out elements, which can lead to misalignment. Thus, it is important to know the impact scope with the purpose of performing a full adaptation. When reviewing the literature in the Business-IT alignment research field, we found that there are no works dealing with this aspect. However, several works in adjacent areas have studied change management. In this paper, we report a systematic review of related work in these areas and extract a set of clues applicable to the Business-IT alignment domain which results in a change analysis framework and a set of rules to estimate impact scope and potential adaptation. Framework elements and rules are illustrated by means of an industrial case study

  • Comprehensive Three-Layer Trust Management Model for Public Cloud Environment   Order a copy of this article
    by Vikas Kumar, Prasann Pradhan 
    Abstract: Public Cloud Offerings are gaining a lot of popularity as they offer consistent savings to the users by their pay-as-you-go model. Parties involved in public cloud transactions may be unknown to each other, however the users need to access the services of unknown cloud providers or third parties and even handover their significant data. Then the genuineness of the service providers or users becomes the most important concern. An established trust between the parties can help in creating sustainable transactions as well as long lasting business relations. To manage and build the trust, there is a strong need of trust management mechanism, which can fulfil the requirements from both the customer and provider perspective. Present work proposes a three-layer trust management model in public cloud environment, which can accomplish the expectations from both the viewpoints and can also support in building a long-term trustworthy relationships between them.

  • A New Technique for Data Encryption Based On Third Party Encryption Server (TPED) to Maintain the Privacy Preserving in the Cloud Environment   Order a copy of this article
    by Ashraf Aljammal 
    Abstract: As the cloud datacenters are exposed to a various types of attacks, data theft/leakage is considered one of the vital attacks that may affect datacenters credibility. In this paper, a new technique is proposed to store the users data in an encrypted form in the cloud datacenter via a third-party-encryption server. There-fore, the attackers and the datacenter authorities will be able to deal only with an encrypted form of the data. Furthermore, to decrypt the data, they need to know the encryption algorithm as well as the encryption key which is in turn placed on a third-party-encryption server. In addition, using third-party-encryption server (TPED) will lead to reducing the workload on both the cloud servers and the data owners machine.

  • A bottom-up approach for creating goal hierarchy using OLAP query recommendation technique   Order a copy of this article
    by Ranjeet Kumar Ranjan, Parimala N. 
    Abstract: Traditionally, data warehouses have been designed guided by an analysis of the underlying data sources. On the other hand, goal-oriented approaches build a goal decomposition structure which is further mapped to a data warehouse model. Goal-oriented approaches address the requirements of the decision makers. In this paper, we propose to build a goal decomposition structure for traditional data warehouses. As a result it can be assessed whether the existing data warehouse model satisfies the decision makers requirements. The approach is bottom-up wherein the tasks are identified first and the path to the strategic goal is built later. The tasks themselves are identified using OLAP query recommendation technique.

    by Sangharatna Godboley, Arpita Dutta, Durga Prasad Mohapatra 
    Abstract: After deployment, testing and validation techniques have become an important requirement for the reliability of software. However, these techniques do not measure energy that they consume, which is also an important parameter for software systems with short energy budgets. In this paper, we propose a new energy conservation technique. This novel technique does not affect the coverage percentage, but reduces the energy consumption. Energy conservation is based on test case minimization technique according to Modified Condition/Decision Coverage (MC/DC) requirements. Our experimental study shows that, as compared to existing work, our proposed approach achieves less energy consumption. On an average of five programs, we save 40.8% energy consumption

    by Rakesh Raut, Pragati Priyadarshinee, Manoj Kumar Jha, Manoj Kharat 
    Abstract: The purpose of this research article is to measure the business performance through Cloud computing adoption in Indian industries. Data collection was done through a questionnaire based survey that was completed by 660 managers from Indian industries. The derived hypotheses were tested using structural equation modelling. The results show that six out of eight hypotheses were supported for cloud computing adoption to measure business performance. The research model has been tested empirically through three phases: exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modelling (SEM). The findings are: (1) trust is having a major impact on cloud computing adoption followed by perceived IT security risk, technology innovation, risk analysis, management style; (2) usage of technology and industry use are having very insignificant effect on cloud adoption rate. This research identified trust as a major factor influencing the cloud adoption rate. However, further research is required to fully understand all the aspects involved especially with the growing number of vendors available. Some more sub-factors can be derived for business performance which can be analysed through second-order SEM. In the final survey with 660 managers, two factors top management support and market place establishment have been confirmed and found are the most important criteria for cloud computing adoption. So, from this study service, manufacturing and power sectors are benefitted in terms of the business performance. This research provides original insight for cloud computing adoption within Indian industries from a managerial perspective.

A questionnaire was developed based on an extended technology acceptance model (TAM). A total sample of 353 university students from various universities in Saudi Arabia participated in this study. After performing the satisfactory reliability and validity checks, the hypothesized model was tested using structural equation modeling. The findings of this study revealed that perceived usefulness (PU) and perceived ease of use (PEOU) are significant determinants of e-learning recommenders system initial acceptance. The results also showed that the service quality, a newly added external construct, has significant impact on perceived recommender system ease of use. User experience of recommender system, the second newly added construct, was found to have a significant effect on perceived recommender system usefulness. Finally we found that students acceptance of e-learning recommender systems positively and directly influences their continuance usage intention. Overall, the proposed model achieves acceptable fit and explains 55% and 42.8% of the sample variance for this studys key target constructs (i.e. user acceptance and continuance usage intention of e-learning recommender system, respectively) which is higher than that of the original TAM. Our findings suggest that service quality, user experience and TAM factors (i.e. PU and PEOU) are important to consider in explaining students' acceptance and the continuance usage of e-learning recommender systems.

  • Predicting e-commerce adoption in small hotel: the role of technology-organization-environment framework   Order a copy of this article
    by Nurhadi Nurhadi, Margo Purnomo 
    Abstract: This study aims at explaining the determinants of e-commerce adoption at firm level based on the technology-organization-environment framework. The population of this explanatory research included small hotels in Bali Indonesia which had implemented e-commerce system for at least a year. The result of the analysis showed that the four variables (relative advantage, organizational readiness, management commitment and external pressure) had a significant effect to the adoption of e-commerce system. Whereas statistically, the effect of the compatibility was not significant. Future researchers are expected to take more than one respondents as the informants in each of the selected hotel as the unit of the analysis. The result of this study proposed a practical implication suggesting that hotels need to consider the aspects of financial, technology, and human resources as an organizational readiness in implementing e-commerce system.

  • An Event-Driven Dynamic Cross-Layer Business Process Compliance Monitoring and Analysis Framework   Order a copy of this article
    by Sridevi Saralaya, Rio D'Souza, Vishwas Saralaya 
    Abstract: A key feature of any Business Process life-cycle is to persistently monitor adherence to compliance from various sources thus helping in detection, analysis and recovery from anomalies. Whenever a business process implemented as Service-Based System (SBS) deviates from compliance obligations it is imperative to overcome the anomalies, so that requirements of the business process are not adversely affected. This necessitates a monitoring and root-cause analysis process. Performance of the SBS is determined by several factors such as goals \& objectives of Business layer; output data, execution time \& number of services in Service layer; processing load, storage capacity, etc. of the Infrastructure layer. Current approaches to compliance monitoring are inadequate for this purpose as they observe and verify adherence to compliance properties in any one of the layers of the SBS. To identify the exact source of anomaly, the cause that may be rooted in any layer should be analyzed to propose effective recovery actions. We propose a monitoring and root-cause analysis framework capable of congregating and correlating events from all three layers of the SBS. The prototypical implementation based on event paradigm is non-invasive with the business process and hence introduces no overhead to the system under consideration.

  • A Three Pronged Technique For The Intelligent Ranking of Cloud Service Providers   Order a copy of this article
    by Tina Esther Trueman, Narayanasamy P 
    Abstract: Small and medium enterprise systems need to be preserved which is a necessity for our country as the growth is at the grass root levels. Cloud Computing can be a solution to help preserve the small and medium enterprises by promoting their services through the web as they can avoid huge infrastructure costs. However, most of the enterprise practitioners are not technology savvy, and it will be a daunting task to choose the best select service provider from the vast number of cloud service providers present. Hence, in this paper a comprehensive three pronged technique which will facilitate the easy selection of Cloud Service Providers is proposed. An Interval valued Fuzzy Soft Sets algorithm is used to rank the cloud service providers based on the user ratings of the cloud service providers. The information regarding the cloud service providers has been collected to create an ontology to match the service providers with user requirements. This suite of tools can be used by the enterprise owners to select the best cloud service provider for their requirements with minimum IT knowledge.

    by Hamad Balhareth 
    Abstract: The previous studies have significantly showed that Business-IT alignment is practically very important for the performance of the organisation. Its value is being derived from the influence of strategy on the outputs of the business. Hence, Business-IT alignment is recognised as very important for the profitability of the organisation. On the other hand, the previous studies have a limited focus on the two approaches: strategy content and strategy process, as impacting to the organisational performance. Therefore, this research study attempts to fill the gap in the literature and to test the relationship between Business-IT alignment and performance .The survey was conducted in universities along with assessing the contribution of strategy content and strategy process in the effects of strategic alignment on the performance. The data collected from the survey is used in the context of Saudi Arabia. The findings of the study show that the positive effects on the performance in the strategic alignment are statistically significant, where the effects can be varied in the absence of either strategic content or process.

  • What Managers Think about Big Data   Order a copy of this article
    by Ossi Ylijoki, Jari Porras 
    Abstract: Digitization progresses rapidly, producing vast amounts of big data. Companies can innovate their business models by using big data and related technologies. Some industries and companies are already on their way towards more data-driven businesses, but for most organizations this is an uncharted territory. The process is first and foremost a business transformation issue. Management leads the change and sets the pace; therefore the attitudes and intentions of executives towards big data are important in the transformation process. This survey concerns the behavioural intentions of Finnish executives with regard to big data. Building on a well-established technology acceptance model we explored the factors that explain the intentions. According to the results, executives intend to take actions that will promote the utilization of big data. They have either experienced or expect big data to be beneficial to their business, especially with regard to current products or services, streamlining of processes and increasing customer understanding. In addition to the generally positive attitude towards big data, the results reveal significant differences between respondents with big data experience compared to the inexperienced ones. The role of IT management seems to play an important role in the differences.

  • Efficient enhanced Intrusion identification and response system for MANETs   Order a copy of this article
    by SANTHOSH BABU A V, MEENAKSHI DEVI P, SHARMILA B 
    Abstract: Mobile ad hoc networks (MANETs) are the new generation of self organizing networks that offer unrestricted mobility without any underlying infrastructure. It relies on the cooperation of all the participating nodes. Due to diverse nature of MANET routing is the major challenge. Security for MANETS has become a difficult problem than the security in other networks. Authentication and encryption would be used as the primary defense. Second level of defense to detect and respond to the security problem called an Intrusion identification system. In this paper, two phased enhanced intrusion identification and response (t-EIIAR) system for multi hop cluster based MANETs is proposed. The two phases of the proposed method (1) cluster formation and cluster head selection (2) the enhanced identification and response system. The fuzzy c means algorithm (FCM) is used to form the cluster and the Intuitionistic Fuzzy TOPSIS (IFT) method used to calculate the trust value for each node in the cluster, based on the trust value select the cluster head and identify the intrusion levels. Finally the intrusion response action is performed from the intrusion level classifications. In the performance analysis, t-EIIAR system maximizes the intrusion detection ratio, network life time and minimum energy consumption in both transmitter and receiver side.

  • Implicit Feature Identification for Opinion Mining   Order a copy of this article
    by Farek Lazhar 
    Abstract: In Opinion Mining area, mining consumer reviews can give a finer-grainedrnunderstanding of consumer needs, which can efficiently help companies and merchants to improve the quality of their products and services. However, identifying features on which consumers express their opinions and sentiments, is not always a simple task. Some existing approaches that attempt to extract implicit features using opinion words as clues or co occurrence techniques lead to unsatisfactory results, and that due to the ambiguity caused by common opinion words which are often expressed on various features. In this paper, we propose, an approach based on Association Rule Mining (ARM) and classification techniques. The first step, consists of creating from a corpus, a set of association rules regrouping explicit feature-opinion pairs. The second step, consists to use this set to build a classification model able to predict for each given set of opinion words the appropriate target. Tested on many classifiers, experimental results show that our approach performs better when incorporating many opinion words than using single ones.

  • Managing Digital Infrastructures: Negotiating Control and Drift in Service Provisioning   Order a copy of this article
    by Nils-Petter Augustsson, Agneta Nilsson, Jonny Holmström, Lars Mathiassen 
    Abstract: The digital infrastructure literature provides important perspectives on the intrinsic relations between information systems in todays organizations. However, little attention has been paid to the challenges involved in providing requisite digital infrastructure services to organizations. In this paper, we argue digital infrastructure service providers operate in highly complex and uncertain environments. Rather than adopting a traditional approach to control, providers must therefore continuously negotiate a balance between control and drift as two complementary strategies. Our argument is based on a retrospective longitudinal case study of a Swedish infrastructure service team within a large international firm. Using the encounterepisode process model as structuring principle and focusing on the tension between control and drift, we analyze the evolution of the providers efforts to manage a portfolio of digital infrastructure services over a period of ten years. Based on these analyses, we uncover the involved complexities and dynamics, how control efforts and drift constituted and how the infrastructure services were managed by continuously balancing control and drift. In conclusion, we relate the findings to extant literature to discuss new insights into provider management of digital infrastructure services.

  • A Semantic Matching Engine for Web Service Composition   Order a copy of this article
    by Rouached Mohsen 
    Abstract: One of the main assets of service-orientation is composition, which consists in developing higher-level services by re-using well-known functionality provided by other services in a low-cost and rapid development process. However, considerable differences on structural, semantical and technical levels along with the growing number of available Web services makes their discovery a significant challenging task. Therefore, services compatibility is an essential pre-requisite to service composition. Measuring the similarity of services is an important and valuable task to get useful information about their compatibility. Similarity measure can be considered as an optimization step before composing services since it enables to reduce the search time by classifying functionally similar services. This paper presents a practical approach to measure the similarity of Web services. Both semantic and syntactic descriptions are integrated through specific techniques for computing similarity measures between services. Formal Concept Analysis (FCA) is then used to classify Web services into concept lattices, and therefore generate a hierarchy of classes of similar Web services. Following this step, a composition engine takes as inputs the set of similar services and the specification of the required service, and generates the candidate composition plans that realize the goal. To determine the composition plan, the composition is reduced to a planning problem.

  • Effective Selling Strategies for Online Auctions on eBay: A Comprehensive Approach with CART Model   Order a copy of this article
    by Yanbin Tu, Y. Alex Tung, Paulo Goes 
    Abstract: Most existing studies on selling strategies in online auctions do not distinguish auction heterogeneity when providing operational selling recommendations. They also tend to assume single objective for sellers. In this study, we incorporate seller and product heterogeneity into our analytical framework and implement data mining analysis in four auction segments. We use classification and regression tree (CART) to identify the critical factors along with their sequences for auction success and prices. We find different determinants for auction success and ending prices in these four auction segments. The classification and regression trees provide operational choices for sellers to build the most effective selling strategies. We propose that, by using expected auction prices with the classification and regression trees, sellers can integrate auction success and prices as multiple objectives in their selling strategies. Overall, this study contributes to the literature by providing an innovative methodology for effective selling recommendations, which can potentially lead to significant and smooth growth of the online auction market.

    by Kamran Syed, Neda Barqawi, Lars Mathiassen 
    Abstract: Software is increasingly developed in a recurrent fashion. Still, we lack theoretical knowledge and conceptual models for continuously improving software release management in such dynamic contexts. In response, we conducted an action research study to improve Software Inc.s capability to recurrently release a specific software service, Secure-on-Request. Drawing on contextualist inquiry as theoretical frame, we addressed an initial problematic situation with a recent software acquisition, complexity of service delivery, new engineering and product management teams, and low process maturity to improve the organizations approach to software releases. As a result, we offer a detailed account of the process of, the content of, and the context for transforming release management at Software Inc. through the phases of diagnosing, establishing, acting and learning. Based on these insights, we theorize Release Cycle Management (RCM) as a key practice that integrates software process improvement into recurrent delivery of software. Moreover, we offer a conceptual model for RCM that software managers can use to implement such practices into their organizations.

    by Alan D. Smith, James Shock, Robert Beaves 
    Abstract: As retail consumers are using mobile devices to access the Internet for information and actual purchases, retails are trying to create promotional campaigns that take advantage of this trend by offering digital coupons? However, there are a number of consumer preferences than marketers need to understand when creating marketing strategies. A survey addressed 5 factors that could affect a customers likelihood of utilizing e-coupons. It was hypothesized that customers will consider themselves loyal customers, but will change their purchase habits for retail (e.g., clothing and accessory purchases) and electronic goods due to an e-coupon offer. Customers disliked e-coupons with threshold values regardless of their annual income. Customers will consider coupon misredemption fraud as an issue for businesses in a negative light, but will admit to searching for coupon codes online. Most of the hypotheses were found to be statistically significant, suggesting management may need to re-evaluate its strategy the B2C retail industry and change how retailers implement e-coupon campaigns as a vehicle to drive CRM initiatives.

    Abstract: Nowadays, Cloud Computing becomes the most widespread environment that provides several services over the internet. However, improving the customers' trust with cloud computing requires monitoring and ensuring the quality of the provided services continuously. Therefore, this paper provides a model for the process of monitoring the Service Level Agreement (SLA) to maintain specific Quality of Service (QoS) parameters. The proposed model assists in monitoring the cloud with multiple Virtual Machines (VM's) in the same environment, which belongs to the same customer. The core foundations for this model are: SLA, QoS parameters, multiple VM's and violations' penalty assessment. This model helps in enforcing and monitoring the service level agreement (SLA). Moreover; observing the quality of service within multiple virtual machines environment, which is described as complex, resource consuming and imposes workload over the cloud system. The proposed model for monitoring the (QoS) parameter in multiple VMs environment works dynamically and checks for any violation. Moreover; the penalty for each violation will be calculated and informed to the customer and provider at the same time. The same SLA which belongs to the same customer and a specific provider will be monitored and managed through multiple VMs. The proposed model depends on the time factor while running the VMs in sequentially manner with a short period of time as a gap between each VM. The proposed model will prevent any interception between VMs and can maintain synchronization.

  • Building Federated Data Warehouse Schema Using Web Service Approach   Order a copy of this article
    by Nouha Arfaoui, Faiçal Felhi, Jalel Akaichi 
    Abstract: The data warehouse is considered as a repository that stores data from disparate sources. It is used mainly in the process of decision making. Because of the diversity of the applications, their heterogeneity and their physical spacing, building a data warehouse, to make decisions in a federated architecture, is a very complicated task. To overcome this problem, we propose a new approach for the design of a federated data warehouse schema based on the web services. The latter are applied because of their capacity to solve many technical problems related to the integration of data source in a federated environment. The proposed solution is based on the bottom-up approach where the data warehouse schema is generated from the set schemas of the data mart. It is composed by two steps. In the first one, a web service is used to generate the schemas of the data mart one for each data source. In the second step, a second web service is used to merge the generated schemas to build the final schema of the data warehouse.

    by Risto Silvola, Arto Tolonen, Janne Harkonen, Harri Haapasalo, Tarja Mannisto 
    Abstract: The growing importance of product data management and master data necessitate companies to have practices for deriving product master data from their corporate strategy. Business drivers need to be understood from the perspective of corporate strategy to capture product master data in relevant systems in a straightforward manner. Ideally master data is created only once and used through the life-cycle of the product. This study clarifies the foundations for determining one product data from corporate strategy. Data definitions are analysed to understand its linkages to business drivers, whereas main business processes are used to support categorisation. The practices of three companies are analysed to understand how business drivers for new products impact product data requirements. The results highlight the importance of business drivers in defining one product data based on the product master data, business-process related product data and IT systems over the product life-cycle.

  • A study of Feature Selection techniques for predicting customer retention in Telecommunication sector   Order a copy of this article
    by E. Sivasankar, J. Vijaya 
    Abstract: Churn is a termination of a contract between customer and company or quitting customer using the product or service. The goal of Churn Management (CM) is to reduce customer losses and retain profitable customers. Churn prediction is an important measure that leads to the solutions for the development of any business or industry; mainly it has lots of impact in telecommunication field. The eventual aim of the organization is to retain the existing customer base, because adding new customers may need investment of money, human resource and additional time. In the current era many researches and industries focus on effective research on churn prediction. Based on the analysis of works performed in the past, it is comprehended that there is some lagging in identifying necessary features in the telecommunication field and also the performance of the telecommunication sector is challenging due to the highly complex dimensional data sets.Feature selection is the process of eliminating irrelevant features from the data set, while maintaining acceptable classification accuracy. The selected features play an important role which can directly influence the effectiveness of the resulting classification. In this paper, a methodology is proposed consisting of two phases, attributes selection and classification based on the attributes selected. Phase one uses a Filter and Wrapper method for attribute selection with Random over-sampling (Ros) through which the size of attributes set and misclassification error can be reduced. In the second phase, the selected attributes are taken as inputs by classification techniques like Decision Trees(DT), K-Nearest Neighbor(KNN), Support Vector Machine(SVM), Naive Bayes(NB) and Artificial Neural Network(ANN). In this work the data set KDD Cup 2009 is used for evaluating the performance. Finally True Churn, False Churn, Specificity and Accuracy are measured to evaluate the efficiency of the proposed system and it is found that the above mentioned methodology performs well ahead for churn prediction and suits well for the telecommunication sector.

    by V. Raj Kumar, L. Suganthi 
    Abstract: In todays tech-savvy society, social media platforms revolutionize the way in which people communicate and share information with each other. These platforms enable customers to instantly and openly convey their opinions, criticisms and praises on various topics pertaining to products and brands. Hence it becomes imperative for organisations to integrate social media information into their CRM strategy. In this paper, relative efficiency of the Social CRM packages using fuzzy AHP/DEA:AR-CCR was determined by considering price as the input criterion and functionality, product quality and customer support as output criteria. Using fuzzy AHP it was found that product quality (41.66%) is the most important criteria followed by functionality (33.29%) and customer support (25.05%). Pipedrive and Really Simple Systems were found to be relatively more efficient. In this manner a Social CRM package that best fits an organisations customer-centric work culture is selected. The Social CRM vendors can utilise these results to benchmark their packages against their competitors.

  • An Adaptive Algorithm for Frequent Pattern Mining over Data Streams using Diffset Strategy   Order a copy of this article
    by Subbulakshmi Balasubramanian, Deisy Chelliah 
    Abstract: Frequent pattern mining using sliding window over data streams is commonly used due to its wide applicability. Determining suitable window size and detection of concept change are the major issues and can be addressed by having flexible window based on amount of changes in frequent patterns. For mining frequent patterns over data streams, vertical mining algorithms can be used. However, in these algorithms, size of transaction identifiers (tidsets) and the time for computation of intersection between tidsets is large. Moreover, presence of null transactions does not contribute any useful frequent patterns. A new algorithm called Recent Frequent Pattern mining based on Diffset with Elimination of Null Transactions (RFP-DIFF-ENT) over data streams using variable size window is proposed. It stores difference of tidsets and eliminates null transactions which minimize memory and mining time. Experimental results show that proposed algorithm saves computation time, memory usage and minimizes the number of frequent patterns.

    Abstract: Tourism is an attractive sector for economic development as it offers potential economic benefits for developing countries. Most tourism sectors throughout the globe consist of Small and Medium-sized Enterprises (SMEs) and as such, tourism SMEs (SMTEs) utilization of Mobile commerce (M-commerce) is crucial in terms of added efficiency, effectiveness and innovation. However, there is a low level of acceptance for M-commerce applications in SMTEs in most developing countries. In such countries, effective applications and factors that impact the acceptance rates of M-commerce in SMEs, is still in the early stage. More importantly, the factors impacting the application of M-commerce are still ambiguous and the relevant theories for M-commerce acceptance have largely been untouched in literatures in the context of developing countries, particularly in Jordan. The paper aimed to test the factors influencing the acceptance of M-commerce application among SMTEs. The questionnaire was distributed to the target sample and the obtained data from questionnaires was analyzed through the SPSS statistical software. Results of the analysis revealed that all factors positively influenced behavioural intention to use M-commerce application in such enterprises. The study provides advanced knowledge of users acceptance of M-commerce in SMTEs, which will help the M-commerce providers in such enterprises to understand the factors that influence the acceptance of M-commerce in SMTEs, which in turn, plays an important role in increasing the acceptance level of M- commerce in SMTEs.

    by C. SriVenkateswaran, Sivakumar D. 
    Abstract: Wireless sensor networks are widely deployed for wide range of applications for gathering information about the desired application. In general, sensor nodes sense their environment, collect sensed data and transmit it to the base station. During this transmission of sensed data from node to sink there is a lot of energy get reduce. In-order to overcome this problem, some of the researchers used cluster head-based approach to send the data to the sink node. The cluster heads collects all traffic from their respective cluster and performs data aggregation before transmitting the data to the sink. In this paper, we have presented the approach for cluster head selection for data aggregation in wireless sensor network. For clustering the node, the proposed method is use hybrid k means and fuzzy c means clustering algorithm. Then we select the cluster head from each cluster. Every node in the wireless sensor network sends their sensed data to the cluster head. The data aggregation is done in the cluster head. Finally base station is received the data from one cluster head, in order to reduce the transmission time here the proposed method is remove the duplicate data and then secure transmission is done by Elliptic curve cryptography (ECC). The performance of the proposed technique is evaluated by overall running time and also the encryption and decryption time. Finally, the simulations are performed and the results are analyzed within the simulation set up to determine performance of the proposed algorithm in the sensor network.

  • Designing an e-commerce recommender system based on collaborative filtering using a data mining approach
    by Samira Khodabandehlou 
    Abstract: E-commerce recommender systems have been converted to a very important decision-making helper for customers, due to the wide variety of goods and services offered by e-commerce companies. These systems provide online personalized recommendations using information technology and customers’ information. In the meantime, Collaborative Filtering (CF) recommender systems are one of the key components of successful e-commerce systems. Despite the popularity and successes of CF, these systems still face a series of serious limitations, including cold start, Sparsity of user-item matrix, scalability and change of user interest during the time that impede exact recommendations to customers. Although much research has been presented to overcome these limitations, but no comprehensive model is yet offered to reduce them. Therefore, the present research aims to eliminate the limitations of CF and to provide a comprehensive system by employing a set of data collection methods in order to present the best and most reliable recommendations to customers for product selection. The proposed system has been implemented in 5 stages including: 1. Customer segmentation based on LRFM variables in the level of product category to evaluate the Length of customer relationship with the company, Recency, Frequency, and Monetary of purchasing product categories 2. Extracting association rules based on user-category matrixes in the level of each cluster 3. Customer segmentation according to demographic variables 4. Change of user-item matrix and reduction of its dimensions 5. Developing a new similarity function by weighted combination of results of segmentation methods and CF. According to the gained results, the proposed system of this research has resulted in the removal of traditional CF constraints and presenting more accurate and appropriate recommendations for the preferences of customers.

  • A conceptual framework of e-loyalty in social-based e-commerce   Order a copy of this article
    by Bushra Alhijawi, Hourya Douglass 
    Abstract: The social-based e-commerce as we named is a type of e-commerce, which appeared as a result of widespread use of social networks like Facebook, Instagram, YouTube, and Twitter. The retailer in social-based e-commerce depends on the personal profile, pages, or groups on the social networks to present their products. In this study, we investigate the factors that affect the customer satisfaction and e-loyalty in this type of e-commerce. Four factors are proposed (i.e., usefulness, usability, customer services, and customisation) that may have an impact on customer satisfaction and may derive the e-loyalty in social-based e-commerce. Online survey was distributed and 95 complete and valid questionnaires were returned. All the four factors have a positive impact on customer satisfaction. In addition, the customer satisfaction has a positive impact on e-loyalty in social-based e-commerce. The findings suggest that to determine e-satisfaction in SEC, the merchants need to focus on providing a handmade, tailor-made, variant colours and sizes products, special attention by the salespersons and deliverymen to the customers. This will reflect on the loyalty of the customers.

  • User acceptance of business intelligence application: motivation to learn, technology, social influence, and situational constraints   Order a copy of this article
    by Tom E. Yoon, Bong-Keun Jeong, Biswadip Ghosh 
    Abstract: Organisations have implemented business intelligence (BI) applications to realise a variety of organisational benefits. However, a majority of BI application implementation projects are unsuccessful. One of the main reasons for the failure is end user resistance to adopt BI applications that their organisation chose. Therefore, it is important to understand how to facilitate individual adoption of BI application. Based on a survey collected among enterprise resource planning (ERP) system users in large to medium sized organisations, this study finds individual intention to adopt a BI application is positively influenced by their motivation to learn the BI application. In addition, the results show that the users' motivation to learn a BI application is influenced by the relative advantage of the application and situational constraints, such as requisite skills/resources and organisational learning climate. These findings provide some practical implications that can help organisations to promote the adoption rate.

  • The relationships between definitions of big data, business intelligence and business analytics: a literature review   Order a copy of this article
    by Kenneth Mashingaidze, Judy Backhouse 
    Abstract: Advances in technology and increasing data volumes have led to new tools and techniques to exploit data and improve decision-making. Terms used to refer to these tools and techniques include big data (BD), business intelligence (BI) and business analytics (BA). Definitions of these terms are not agreed on. In particular, the terms are used as subsets or special cases of each other and this leads to confusion about their meaning and how they relate. This paper examines both academic and practitioner literature that deals with two or more of the terms to synthesise definitions and describe the relationships between them. BD is data with high volume, variety of sources and high velocity. BI is a set of tools and techniques to use data for decision-making. BA is an advanced form of BI. BD is data that can be used in both BI and BA.

  • Performance optimisation of the decision-support queries by the horizontal fragmentation of the data warehouse   Order a copy of this article
    by Mohamed Kechar, Safia Nait-Bahloul 
    Abstract: The horizontal fragmentation of the data warehouse is considered as one of the important performance optimisation techniques of the decision-support queries. This optimisation is reached only if the large data volume of the fact table is horizontally fragmented. For that, the fragments of the fact table are always derived from the fragments of the dimension tables. Unfortunately, in this type of fragmentation, the fragments number can dramatically increase, and their maintenance becomes quite hard and costly. Thus, to reduce the number of the fragments and to further optimise the decision-support queries performances, we propose to fragment horizontally only the fact table by exploiting jointly: the selectivities of the selection predicates, their occurrence numbers, and their access frequencies. To prove the effectiveness of our fragmentation technique, we present at the end, a set of experimental results conducted under Oracle 10g on the APB-1 benchmark.
    Keywords: decision support system; data warehouse; query performance optimisation; horizontal fragmentation; selection predicates; fragmentation predicates.

  • A User Study on Trust Perception in Persuasive Technology   Order a copy of this article
    by Wan Nooraishya Wan Ahmad, Nazlena Mohamad Ali 
    Abstract: A wide range of persuasive technologies has been developed for many different issues to assist people in changing their attitude or behavior. However, whether or not users trust persuasive technology and which trust perception affects them more in making trust decision are yet to be found out. Therefore, this study aimed to examine users trust level and its trust perceptions using two types of persuasive technologies, for example, health application and educational games on the environmental issues. The questionnaire is used as an instrument to measure trust level and trust perceptions. A pre-and-post-test approach is used to study 25 participants who are required to use both types of persuasive technology concurrently for 6 weeks. The finding shows that the users trust is at low-level, indicating a significant lack of trust problem. Cognitive trust dominates the trust decision-making though it is correlated with affective trust.

  • E-Collaborative Learning experience, Interdependencies of Presences and Learning Outcomes: Evidence of Mediating and Moderating Effects   Order a copy of this article
    by Alimatu-Saadia Yussiff, Wan Fatimah Wan Ahmad, Emy Elyanee Mustapha 
    Abstract: E-collaborative teaching and learning have gained much attention from practitioners, businesses and academics. However, the impact of e-collaborative teaching and learning on students learning outcomes with the mediating and moderating effects of three presences (social, cognitive and teaching presences) has not been thoroughly investigated. To bridge this gap, we conducted an experimental research design consisting of two main groups experimental and control groups. The control group, consisting of 42 students is the group using the conventional methods of in-class collaboration. The experimental group, consisting of 60 students used a developed e-collaboration system after which a survey was conducted using four sets of instruments the Community of Inquiry Survey Instrument, effectiveness for teamwork survey, pre-test and post-test questions. Partial least square approach to structural equation modeling was employed to analyze the experimental groups data based on the hypothesized relationship model. The results demonstrated that the constructs in the hypothesized model are reliable and valid. In addition, findings also indicated that e-collaborative learning experience strongly predict learning outcomes indirectly through the mediating and moderating effects of the three presences. This research offers significant contributions to practice, research and theory.

  • Mobile Decision Support System with Dynamic Knowledge Base using Decision Tree and Case-Based Reasoning   Order a copy of this article
    by Hasimah Hj Mohamed, Muhammad Rafie Hj Mohd Arshad, Muhammad Dzulhimi Azmi 
    Abstract: Muslims from around the world performing Hajj and Umrah every year. The rituals involve many rules and procedures in which can become a challenge for pilgrims to remember. While performing the ritual, pilgrims might encounter some problems that need an immediate solution, especially those related to dos and donts in the ihram. The best way to get the solution is by referring to the ustaz or muttawif (Hajj Guider). However, theyre limited and not available all the time. It is best to have a knowledge that can be stored digitally that enable the pilgrims to refer it anytime and anywhere. We proposed a dynamic knowledge-based approach that can capture possible problems and solutions from the expert on mobile platform. Users can query both simple and advance questions to the system. The system is on android and web based platform. The system has been implemented using an artificial intelligence method of Decision Tree and Case Based Reasoning methodology. We use case based reasoning to retrieve similar cases (Question and Answer). Decision tree with dynamic knowledge based is being used to predict the solutions for problems inquired by users. Rules are stored in databases, and it will be retrieved according to the problems given. We have implemented these methods on hajj domain to solve the dumm imposition for the ihram ritual which can be referred by pilgrims anywhere and anytime to solve any problems encounter during hajj ritual.

    Abstract: Mental health presents as one of the greatest challenges to the current generation. It has been reported that about 5% of the population in developed countries are affected by Generalized Anxiety Disorder (GAD) withwomen twice as likely to be affected as compared to men. Predicting GAD among women is no longer an arduous task especially with the assistance of data mining technology. In this paper, a methodology encompassing data collection, data preprocessing, data analysis and data mining process using random forest approach is drawn for an effective prediction. The random forest approach is one of the classification data mining techniques which is embedded with good predictive characteristic. The result of this study in term of accuracy, sensitivity and specificity conforming to its high predictive performance in GAD prediction based on depressive symptoms. Besides that, several popular machine learning techniques are also applied to the resultant dataset of this study and the comparison result attests to random forest algorithm outperformed other methods. The generated prediction model is expected to provide an effective screening process to detect Generalized Anxiety Disorder earlier among women in Malaysia.

    by Deborah Paris, Mahadi Bahari, Noorminshah A. Iahad 
    Abstract: Despite various studies conducted on the implementation of business-to-customer (B2C) e-commerce, prior studies presumed that B2C e-commerce implementation as a plug and play exercise rather than a process-based. This paper presents a model for the implementation process of B2C e-commerce in a fashion and apparel business. Based on qualitative research approach using a case study and summary of experience, a model for the implementation process of B2C e-commerce is proposed. The model describes the characteristics of 14 implementation factors that occurred during Lewins and Kotters stages of implementation. Although the models generalisability is limited, it offers a guideline for the existing and future senior managers of B2C e-commerce in fashion and apparel business. This model helps managers to identify the highlights in each stage of the B2C e-commerce implementation process.

    by Shahla Asadi, Ab Razak Che Hussin, Halina Mohamed Dahlan 
    Abstract: the growing of environmental issues had drawn attention from governments sector, societies as well as business organizations. In fact, organizations have put effort on challenging the environment issues. One of the most important logical efforts that organizations put to deal with environmental issues is Green Information Technology (IT) which, in turn, leads to enhancement in the organisations performance and improvement. Using Green IT by organizations, hence, will be advantageous to the society. There is plethora of research on Green IT in organizations and the adoption of Green IT from managers pro-environmental intention to adopt Green IT was only explored by a small number of them. The Norm Activation Theory (NAT) and the Theory of Planned Behaviour (TPB) have been used in the current research. The study, provides the available recent knowledge about information system which are necessary to monitoring the decision maker's intention for adoption of Green IT and sustainability with the development of a research model which recognizes the important aspects for adoption of green information technology.

  • Validation of a Multimodal Interaction Model for Foot Reflexology Virtual Reality Stress Therapy Application   Order a copy of this article
    by Suziah Sulaiman, Hector Chimeremeze Okere, Dayang Rohaya Awang Rambli, Oi-Mean Foong 
    Abstract: Multimodal interactivity when supported in a foot reflexology virtual reality environment has the potential to relief stress. Current works leading to the development of such an environment have focused on creating models involving human to human (H-to-H) interactions which later could be used as design requirements. The goal is to translate these requirements and lay foundation for future foot reflexology virtual reality stress therapy (VRST) application. Despite the intention, the development missed an important activity that is feedback from those experts in the domain. This paper closes the gap by presenting an expert review to the multimodal H-to-H interaction model as a form of validation. Eight experts from the Human Computer Interaction (HCI) domain or related field reviewed and provided feedback on the model. The reviews were utilized to reconstruct the multimodal H-to-H interaction model, consequently yielding a final validated model for foot reflexology VRST application.

  • An investigation of factors influencing the intention to use mHealth apps for self-care   Order a copy of this article
    by Faiz Aiman Azhar, Jaspaljeet Singh Dhillon 
    Abstract: This paper reports factors that are essential to be considered in the design mHealth apps for self-care. Self-care is an emerging area that refers any intentional actions people take to care for their physical, mental and emotional health. Encouraging people to practice self-care is a challenge and it is known to be an important part of a healing process. There are numerous health support applications in the market that can be downloaded via smartphones. These apps are typically designed to enable healthcare consumers to improve their health or maintain their good health. However, recent research indicates that with the exception of physical activity, more consumers are currently tracking key health factors on paper or in their heads than with mobile applications. In this paper, we identify factors that influence the intention to use mHealth apps for self-care that were identified via a systematic literature review approach and which thereafter were investigated quantitatively by involving 203 consumers. These factors when considered in the design of future mHealth apps could address the requirements and expectation of consumers towards mHealth apps in general and could possibly motivate them to use mHealth continuously in achieving their health goals.
