  • Investigating the Role of Information Technology in Developing the Learning Organization: Empirical Evidence from Egypt   Order a copy of this article
    by Hadia Hamdy, Karim Hodaib 
    Abstract: Developing a learning organization has been associated with organizational growth and innovation as it enables companies to maintain a memory for their created knowledge and experiences that can be shared among all organizational members. The most important tool identified to build such a memory is Information Technology knowledge management systems. However, despite their importance, their actual contribution to the development of the different dimensions of the learning organization has rarely been studied, especially in developing countries like Egypt. This research investigates the effect of using IT knowledge management tools on the development of the learning organization using the dimensions of the learning organization questionnaire developed by Watkins and Marsick. A pre-post quasi experiment was conducted in an Egyptian organization to measure the dimensions of the learning organization before and after the application of a new IT system designed to enhance employees learning and knowledge sharing. Results indicate that the implementation of the new IT system significantly improved all the dimensions of organizational learning except for degree of teamwork that is essential for the process of knowledge integration. It concludes that IT systems facilitate the creation of the learning organization, and convey a positive message regarding organizational commitment to developing and empowering employees towards a shared organizational vision. However, they have to be implemented within an integrated strategy, structure, culture, and policy change management system to be able to achieve the desired outcome of transferring a rigid organization into a learning one.

  • Enhancing Excel Business Tools with Additional Relational and Recursive Capabilities   Order a copy of this article
    by Pedro Ramos, Luís Botelho, Antonio Martins 
    Abstract: This paper presents a new plug in that enriches spreadsheet capabilities mainly in what concerns its potential regarding relational queries and recursive computational processes. Currently some apparently trivial and useful queries can only be handled with the support of programming skills. Spreadsheet users with low computer science skills should have a natural and easy way to handle those queries within the spreadsheet, without relying on external programming (e.g., VBA). The tool we have developed can be used with Prolog technology, and provides those features to the most used professional spreadsheet: Microsoft Excel. Throughout the paper we explore the plug-in features with several business examples.

  • Validation of Cognitive Inhibitors to Technology Adoption using Content Analysis   Order a copy of this article
    by Easwar Krishna Iyer, Sreehari Unnikrishnan, Paul Philip, Mallika Sundarrajan, Bharadhwaj Sivakumaran 
    Abstract: Inhibitors to technology play a crucial role in predicting eventual technology adoption. In the inhibitor space, studies have so far been limited to understanding affective inhibitors only. The central proposition of this paper is to identify two new cognitive inhibitor constructs. This study augments the existing body of knowledge in the area of technology acceptance behavior by positing Dissatisfiers and Risk as two cognitive inhibitor constructs to technology adoption. The methodology used for validating the proposed model is Content Analysis. The target technology chosen for validation is Internet of Things (IoT). The results obtained provide strong support for the proposed hypotheses thereby establishing Dissatisfiers and Risk as two new cognitive inhibitor constructs.

  • Illusion of SNS Influence: Are Popular SNS Influential?   Order a copy of this article
    by DongBack Seo, Martin Bügel 
    Abstract: People influence each other in the environment of social networking sites (SNS). Some SNS have gained popularity. Practitioners and researchers assume that these popular SNS are influential. However, influence and popularity are two different concepts. This research aims to provide two clear concepts of influence and popularity as well as their relationship. Popularity is hypothesized that it is affected by elements in the surroundings (e.g. societal position of a SNS owner) of SNS based on a peripheral information processing mechanism, whereas influence is hypothesized that it is affected by core elements (e.g. quality of content on a SNS message) of SNS based on a central information processing mechanism. The results indicate that influence is solely affected by the central information processing mechanism, but popularity is affected by both central and peripheral information processing mechanisms. There is a relationship between influence and popularity but it is marginal. Therefore, it should not be assumed that popular SNS are influential and vice versa.

  • Information Systems Continuance: The Role of Incentives and Goal Harmony   Order a copy of this article
    by Tove Boee, Boge Gulbrandsen, Tom Roar Eikebrokk 
    Abstract: This paper extends information systems continuance theory (ISCT) and integrates it with a managerial perspective. Our study integrates principalagent theory (PAT) to capture the managerial influence on users continued use of information technology. We argue that the two theories offer complementary explanations, ameliorate each others shortcomings, and enhance our ability to explain and predict IS continuance. As predicted by PAT, the study finds support for the effects of goal harmony and incentives on users continuance decisions. Additionally, goal harmony reduces the positive relationship between incentives and continuance. While the supported ISCT model shows an explained variance of 37%, the full model explains 51% of the variance of the dependent variable, indicating that the integrative model is more powerful in explaining user continuance than is ISCT in isolation. The study advances the theoretical understanding of continued use of IS from both a personal and a managerial perspective and offers proposals for organizational actions.

  • Determinants of Success and Failure of Knowledge Transfer in Information Systems Offshoring: A Ranking-Type Delphi Study   Order a copy of this article
    by Artur Strasser, Susanne Strahringer, Markus Westner 
    Abstract: The transfer of knowledge from client to service provider poses major challenges in information systems (IS) offshoring projects. Knowledge transfer directly affects IS offshoring success. Therefore, associated challenges must be overcome. Our study examines the determinants of success and failure of knowledge transfer in IS offshoring projects based on a ranking-type Delphi study. We questioned 32 experts from Germany, each with more than ten years of experience in near- or offshore initiatives to seek a consensus among them. We identified 19 success and 20 failure determinants. These determinants are ranked in order of importance using best-worst scaling. Aspects of closer cooperation are critical for effective knowledge transfer. This includes regular collaboration, willingness to help and support, and mutual trust. In contrast, critical determinants of failure are concerned with fears and fluctuation of human resources. Hidden ambiguities or knowledge gaps, an unwillingness and disability to share knowledge, and high fluctuation of human resources negatively impact knowledge transfer.

  • How to evaluate brand extension in the mobile Internet environment   Order a copy of this article
    by Wenlong Zhu, Shiye Wang 
    Abstract: How to successfully implement a brand extension has been a common topic among global enterprises. Mobile Internet (M-Internet), a new information and communication technology, creates suitable conditions for enterprise brand extension. However, most researches related to brand extension evaluation focus on traditional information technologies presently. Little research has addressed M-Internet. From the perspective of consumer, this study constructs brand extension evaluation model based on the Task-Technology Fit (TTF) and Aaker and Keller Model (A & K Model), and analyzes the influencing mechanism of brand extension evaluation by using the Structural Equation Modeling (SEM). The final results show that technical characteristics of M-Internet produce a positive effect on attitude of parent brand. Furthermore, attitude of parent brand influences the brand extension evaluation, brand trust and perceived fit positively. Lastly, brand extension evaluation is subject to positive impact of brand trust and perceived fit besides attitude of parent brand. The theoretical and practical implications of this study are discussed lastly.

  • QoE-based service differentiation: An analysis of the business implications for the mobile services market   Order a copy of this article
    by Luis Guillermo Martinez Ballesteros, Per Jonny Nesse, Jan Markendahl 
    Abstract: Mobile network operators (MNOs) face a future characterized with new challenges, such as growing data consumption, a slowdown in subscriber growth and reduced revenues due to the success of over-the-top providers. To remain competitive, MNOs must offer affordable services and provide innovative strategies to retain current customers. Quality of Experience (QoE) is a well-established methodology for measuring and understanding the overall level of customer satisfaction and has also been presented as a way to improve telecommunication services. Even though QoE can be used to solve problems, such as customer loyalty and optimization of network resources in mobile networks, there is still a lack of knowledge on how the MNOs can take advantage of QoE and its potential benefits. In this paper, we explored the implications of the incorporation of QoE feedback in mobile networks at the business level. The analysis, which is based on a combination of value network configuration and business model analysis of scenarios, shows that value-added offers of differentiated and personalized services can be seen as alternatives to generate new revenue streams in the mobile service market. An important finding from our study is that, due to the nature of the challenges facing the mobile services industry, a QoE analysis cannot be limited to only a technical discussion but needs to be combined with an informed analysis of the business implications of the proposed solution.

  • Study on Optimization of Supply Chain Inventory Management Based on Particle Swarm Optimization   Order a copy of this article
    by Liangguang Mo 
    Abstract: Aiming at the problems of poor convergence, high cost and low efficiency of traditional supply chain inventory management model, an optimization method of supply chain inventory management based on particle swarm optimization (PSO) is proposed. Firstly, the whole process of particle swarm optimization (PSO) is described. Secondly, by introducing the inventory of different nodes in the supply chain, this paper studies the supply chain and designs the optimal inventory management model to meet the requirements of the supply chain model. Finally, the particle swarm optimization algorithm is used to design the optimal inventory management model and generate the optimal inventory. The experimental results show that the total inventory cost of the model is only 3.682 million yuan, which is much lower than other traditional models. The results show that the model can effectively reduce the cost of supply chain inventory management, has a high degree of convergence, and can reduce the work intensity of relevant personnel.

  • A reliability and security enhanced framework for cloud-based storage systems   Order a copy of this article
    by Peng Xiao 
    Abstract: In cloud computing environments, reliable and secure data storage service plays a more and more important role in many data-intensive applications. However, existing storage systems either fail to provide them or provide them in a cost-ineffective manner. To provide better storage service in nowadays cloud environments, we propose a novel framework called Reliability and Security enhanced Cloud Storage (RSCS), which consists of several well-designed components to improve low-level data reliability as well as guarantee up-level data accessing security. In the RSCS framework, a simple yet effective file system scheme is proposed, which can mirror striped data among different nodes to improve the reliability while maintaining a high aggregated throughput. A centralized lease-based mechanism is designed to allow simultaneous accesses to different portions of a single file while maintaining the multiple-reader-single-writer semantics to each requested data portion. Finally, we provide a secure data accessing tunnel technology which allows the RSCS to establish secure communication channels between users and storage nodes without introducing too many extra costs. Extensive experiments are conducted in a real-world cloud storage platform, and the results indicate that the performance of the proposed RSCS framework can easily meet the requirements for most of current cloud systems.

  • Automatic recognition and defect compensation for calf leather   Order a copy of this article
    by Yu-Tang Lee, Chung Yeh 
    Abstract: Various defects existed on the surface of calf leather could affect its usable area and the salable price. No international criterion specifies the compensatory credits for calf leather surface defects which cause additional cost between supplier and purchaser in complicated negotiation process. This paper is to develop an artificial intellectual technique to implement the automatic recognition for types of leather defect and to compensate for leather defective unusable area in order to bridge trading gap between leather provider (supplier) and manufacturer (purchaser). An approach starts with scanning the images of collected samples of leather and classifies surface defects into seven categories by using digital image processing technique and blobs analysis which attributes hole, area, perimeter, ratio of perimeter, length and width of defects etc. Data of calf defects from sample is extracted to develop an automatic recognition system via artificial intellectual techniques ANN learning process is introduced to make a sustainable automatic recognition system used to identify types of categories for upcoming leathers under inspection, then incorporated with compensation criterion of specific category for leather defect which is accepted by both parties to conclude compensation credit. Study results the validity and accuracy of automatic defect recognition can meet requirement of practical implementation on leather business transaction; the mean error rate of recognizing leather defect is less than 2.16% and the mean deviation rate for compensation area is 0.03% under this simulated transaction.

  • A Blind Demodulation Algorithm of DSSS by Continuous Wavelet Transform   Order a copy of this article
    by Wei Huang, Xiangmo Zhao, Chao Wang 
    Abstract: This paper proposes a novel blind demodulation algorithm of the Direct Sequence Spread Spectrum Signal (DSSS) modulation with noise by using continuous wavelet transform. We chose Morlet wavelet with similarity and symmetry. The proposed algorithm can demodulate DSSS with a negative signal to noise ratio(SNR) without any prior knowledge. The simulated the bit error rate(BER) curves of the existing blind demodulation algorithms of DSSS are above the theoretical BER curve of the coherent demodulation or coincidence. Simulation result of new algorithm shows that BER curve of the blind demodulation of the wavelet transform is below the theoretical BER curve of coherent demodulation. The novel blind demodulation algorithm allows to obtain an 8dB gain in SNR terms compared with that obtained by the theoretical coherent modulation when SNR is 10^-4 .

  • OBWD: An ontology and Bayesian network-based workflow design platform   Order a copy of this article
    by Chao Dong, Chongchong Zhao 
    Abstract: Workflow management provides a great convenience for the cooperation between different roles in modern industry and business. The task reuse and design automation are challenges of workflow management currently. In this paper, an ontology SDWMO is constructed for workflow resources integration and task request release. An algorithm DOMDM is proposed to achieve the conversion of the data from traditional workflow database to SDWMO ontology. In order to provide workflow templates for designers, we extract statistic-oriented cases from the workflow database. Based on these cases a Bayesian network is established for workflow template recommendation. We have designed OBWD platform to implement the above methods. The experimental data indicates that OBWD is statistically effective and saves a lot of time for workflow designers. Currently, OBWD has been used in space debris mitigation domain for workflow management. Moreover, our methodology can also be applied in many other domains in the future.

    by Mohana Sundaram Kuppusamy, Kalaimani P 
    Abstract: Secure operation and reliable utilization of transmission lines is a challenging issue in deregulated power system. The scheduled power transactions are difficult due to the overloading of transmission lines in restructured power system as the electricity market has become more competitive. Due to congestion of transmission lines, the transfer of real power and the power system voltage profile are greatly affected in the power system. The aim of this research work is to increase the real power and the reactive power flowing in the lines of multibus system using thyristor controlled series compensator (TCSC). Real power transfer with reduced losses and improved voltage stability is an important factor in the present global scenario. This paper deals with the improvement of power flow in power transmission lines by series compensation device in thirty bus system with reduced congestion. The thirty bus system without and with thyristor controlled series compensation device (TCSC) is modeled and simulated and the results are presented. The simulation studies indicate a significant improvement in the real and the reactive power flow with the introduction of TCSC .The advantages of the proposed system include the smooth variations of the real and the reactive powers.

    Abstract: The problem of classifying scenes from cricket video is addressed and a robust framework for this problem is proposed. It is proposed that the finite state machines (FSM) are suitable for detecting and classifying scenes and their usage is demonstrated for three types of events: wicket, six, four. This framework utilises the structural information of the scenes together with the low-level and mid-level features. Low level features of the video including motion and audio energy and a mid-level feature, body, are used in this approach. The transitions of the FSMs are determined by the features from each shot in the scene. The FSMs have been experimented on over 80 clips and convincing results have been achieved.

  • An Improved Mean Curvature Based Bending Model for Cloth Simulation   Order a copy of this article
    by Xiaohui Tan 
    Abstract: In cloth animation, the bending behavior of cloth is important for cloth simulation effects. The presentation of cloth bending properties plays a key role in cloth animation research because cloth is characterized by strong resistance to stretch while weak resistance to bending. This paper proposed an improved approximate nonlinear bending model based on local geometric information. In the dynamic simulation, cloth was divided into several regions according to mean curvature of surface. The bending force was updated according to the changes of the mean curvature in each region. The calculation of bending force was simple and accurate with the proposed model. Experimental results show that wrinkles and folds generated in a natural way with the improved model and the efficiency of simulation is improved compared with the original algorithm.

  • Promoting Business -IT Alignment through Agent Metaphor Based Software Technology   Order a copy of this article
    by Venkatesan Devanathan 
    Abstract: Business-IT Alignment (BITA) not only enables enterprises to synchronise their effort among stakeholders but also facilitates efficient achievement of organizational goals. A strategy to facilitate BITA in enterprises is to adopt suitable Enterprise Architecture (EA). Popular software modeling approaches like unified modeling language (UML), Business Process Modeling Language (BPML) are used in EA to depict its IT models. So there is a direct interdependency or connection among BITA, EA, and software technology. Aligning the modeling terminologies of BITA, EA and software technology, facilitate CASE automation. It also improves traceability among different kinds of enterprise models, and facilitates change propagation. By this enterprises can avoid unnecessary effort to synchronise different models and terminologies using error prone and hard to comprehend model connectors. This result in enhanced stakeholder performance by reducing their effort needed to comprehend and perform BITA, EA and software modeling tasks. The present study evaluates the suitability of the object-oriented and agent-oriented modelling for the development of business model aligned software. EA alignment capabilities of these technologies are compared using Zachman Framework (ZF). The comparison is carried out by evaluating the property of the models of these technologies in filling up the grid cell units of ZF, in a manner preserving the syntactic and sematic relationship between grid cell units. This study presents the fact that agent models provide better business process software model alignment between gird cells of ZF due to the syntactic continuity of model abstractions in grid cell diagrams. It improves stakeholder communication, reduces the possibility of misunderstanding of business flow and augments savings due to fewer errors. This study also demonstrates that models created using agent abstraction can satisfy the information requirements as needed in ISO 19440/19439 and other enterprise modelling standards.

  • Predicting Service Collaboration for Users based on Data Variation Patterns   Order a copy of this article
    by Jiaqiu Wang, Zhongjie Wang 
    Abstract: Service collaboration allows the realization of more complicated business logic by using existing services. Nowadays, users use lots of services in their daily work. For example, developers use a large number of services (e.g., Stack Overflow, Github, Blogger, etc.) to develop programs. Services are used continuously. Since most of the users\' data is distributed in these different service providers, these data are separated from each other although they are correlated. If we coordinate different services based on these correlation data, we can provide users with seamless and effective support. This is very significant because it greatly increases users\' productivity. However, due to the segregation of data, it is difficult to coordinate different services based on data correlation. To deal with this challenge, we propose a novel deep recurrent neural network (runs in a centralized service) to predict future services collaboration and their generated data. The network captures the correlation between different data and discovers patterns of data variation by using multiple hidden layers, which are beneficial to services collaboration prediction. Extensive experiments are conducted on the real world data set. Experimental results show that our model significantly outperforms a few competitive baseline methods.

  • A Caching Strategy Based on Dynamic popularity for Named Data Networking   Order a copy of this article
    by Meiju Yu, Ru Li 
    Abstract: Named Data Networking (NDN) is a prominent architecture for the future Internet. In NDN, routers have the capacity of in-network cache, which can completely improve network performance. However, the cache capacity in routers is limited and how to utilize the cache resources effectively is still a great challenge. To solve the problem, this study presents a dynamic popularity caching strategy based on additive increase multiplicative decrease for NDN (DPCA). DPCA takes content popularity and caching capacity into account and it utilizes AIMD algorithm to adjust the popularity threshold dynamically. At the same time, it also proposes a evict algorithm which takes the historical information of content popularity, the trend of content request and the interval from the last request time into account. The simulation results show that the DPCA strategy can effectively improve cache hit ratio, decrease network throughput and reduce the average hit distance compared with other schemes.

  • A Dynamic Programming-based Approach for Cloud Instance Type Selection and Optimization   Order a copy of this article
    by Pengwei Wang, Wanjun Zhou, Caihui Zhao, Yinghui Lei, Zhaohui Zhang 
    Abstract: With the advantages of cloud computing gradually highlighted, users increasingly want to deploy their applications and services on the cloud to reduce costs and obtain high computing capacity. Nowadays, cloud providers (e.g. Amazon, Microsoft) at home and abroad provide a large amount of cloud instance types optimized to fit different use cases, such as compute optimized and memory optimized. Due to the potentially large quantity of cloud instance types in the public cloud market, it is often a challenge for users to select an optimal set of cloud instance types subject to limited resource capacity. In this paper, a dynamic programming-based approach is proposed for cloud instance type selection, which can provide optimal combination of cloud instance types to users. Experiments are performed based on real-world cloud information to evaluate the proposed method.

  • Learning context-dependent word embedding based on dependency parsing   Order a copy of this article
    by Ke Yan, Jie Chen, Wenhao Zhu, Xin Jin, Guannan Hu 
    Abstract: Word embeddings constitute the basic method of text representation. Whether they are the input to a machine learning algorithm or the features used in a natural language processing application, such embeddings have proven helpful in solving various text processing tasks. In natural language texts, contextual information exerts a crucial influence on the semantics of word representations. In current research, most training models are based on shallow textual information and do not fully exploit deep relationships in sentences. To overcome this problem, this paper proposes the dependency-based continuous bag-of-words (DCBOW) model. This model integrates the dependency relationships between words and sentences into the context in the form of weights, thereby increasing the influence of specific contextual information on the prediction of target words. This method increases the abundancy of word context information and enhances the semantics of word embeddings. The experimental results show that relative to syntactic similarity, the proposed method highlights semantic relations and improves the performance of word representations.

    Abstract: Location-based social networks (LBSNs) make it possible for people to share their visited places by uploading the check-in information. To improve the efficiency of recommendation algorithm, researchers introduce check-in data into point of interest (POI) recommendation to help users find new and interesting place. However, some researches ignore the signification of time factor for POI recommendation in LBSNs. In this paper, we propose a time-based collaborative filtering algorithm according to the similarity between users which combines the global similarity during a long period and local similarity within a short time interval. The experimental results show that the method we proposed can get more accurate recommendation.
