  • 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.

    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.

  • 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.

  • Are You Having a Laugh? Detecting Humorous Expressions on Social Media: An Exploration of Theory, Current Approaches and Future Work   Order a copy of this article
    by Suzanne Elayan, Martin Sykora, Tom Jackson, Ejovwoke Onojeharho 
    Abstract: The role of humorous content on social media has rarely been taken into account in prior work. Understanding its dynamics on social media provides insight that could benefit a range of applications in sentiment analysis. This paper introduces literature on humour theory, related human behaviour and a discussion of existing automated approaches to humour detection. We present and review current research on humorous language use on social media and its significance. In particular, example humorous expressions from Twitter are used to illustrate the heterogeneous types of humour on social media. Since most prior work focused on English language contexts, the analysed example uses of humour are set in the Arabic cultural context, providing a novel view. The primary contribution of this paper is the position that similar to sentiment analysis, automated humour detection in its own right has potential in understanding public reactions and should be explored in future studies.

  • AQINM: an adaptive QoS management framework based on intelligent negotiation and monitoring in cloud   Order a copy of this article
    by Zeng Saifeng 
    Abstract: Recently, more and more federated cloud platforms have been constructed to deal with non-trivial large-scale applications, which typically require certain level of quality-of-service (QoS) guarantee. However, most of existing cloud-oriented QoS solutions are likely to introduce extra overheads on either resource allocation or task execution, which is especially true in federated cloud environments. In this paper, we present a lightweight QoS-enhancing middleware, namely Adaptive QoS Management based on Intelligent Negotiation and Monitoring (AQINM), which provides three QoS-enhancing services including policy management, service-layer-agreement (SLA) negotiation, and SLA monitoring. Unlike the conventional QoS-enable middleware, these services in the AQINM framework introduce several novel mechanisms to offer more cost-effective and efficient solutions to enforcing the QoS management in federated clouds. The implementation of our AQINM framework are tested in a campus federated cloud platform by using different applications as experimental benchmarks, and its performance are compared with other similar solutions. The experimental results indicate that the proposed AQINM can significantly reduce the costs of SLA negotiation and monitoring for large-scale cloud application that deployed in federated cloud environments.

    by Xindong You, Pengfei Guan, Xueqiang Lv, Baoan Lv 
    Abstract: Current existing fine-grained sentiment analysis method usually extract the context of the sentence while ignoring the semantic representation of the target words. We extent the target words in comments as the additional input parameters to the deep learning model in this paper. And the influence of the number of extended words on the models performance is also discussed thoroughly during the experimenting process. Main procedures of our proposed fine-grained sentiment classification method can be described as: (1) Firstly, target words are expanded by using the semantic distance of the word embedding, which used as the key information. (2) Bidirectional LSTM neural network is used to extract the semantic information afterwards. (3) Additionally, the attention mechanism is employed to learn the sentiment weight distribution of the target words among the text automatically. Experiments conducted on the SemEval 2014 Task 4 corpus showed that the proposed method outperforms the other LSTM model.

    Abstract: In this paper, a grid-connected inverter system is deeply researched based on the two-stage single-phase PV grid-connected inverter. Full bridge structure is adopted in the backend inverter circuit. In order to realize the balanced flow of power, to improve the system's response speed and to eliminate the influence of the resonance peak of LCL filter, the three loop control strategy is adopted in the inverter system. At the same time, the reason of generation of the dead-time and its influence on the output of the grid-connected inverter are analyzed in detail. And an improved dead-time compensation method is proposed for zero-current clamping phenomenon. The output voltage error of inverter is extended from two to seven in this method, which effectively solves the problems, such as zero-crossing distortion of the grid-connected current, more odd harmonic content, higher distortion rate and lower amplitude of fundamental wave.

    by Guojian Lin, Weichuan Chen 
    Abstract: In order to overcome the problem that the traditional method only considers the financial report index when designing the early warning model, and ignores the influence of non-financial data on the early warning model, there is a low accuracy problem. Based on the discrete-time risk model, this paper proposes an early warning method of enterprise financial information caused by tax differences. Starting from the establishment of enterprise financial information early warning system, this paper analyzes the importance of tax indicators to enterprise financial information early warning. By studying the early warning system, we select index data in the model, add tax difference indicators, select multi period panel data, and use discrete-time risk model to build enterprise financial information early warning model. The experimental results show that the accuracy of this method is as high as 99.05%, and there is no multicollinearity among the variables in the model, which is reliable.

  • Optimization Decision Model of Enterprise Financial Risk Management Combining Stochastic Demand   Order a copy of this article
    by Dandan Zhao, Lin Li 
    Abstract: The Corporate financial management has certain risks. The influencing factors include the laws of economy, politics, and the market itself. Constructing a suitable enterprise financial risk management model based on the market mechanism can effectively reduce the enterprises financial risks and increase the investment return rate. The random demand is a kind of artificial intelligence optimization decision model with better optimization ability, but sometimes will fall into a local optimal solution. Combining random demand with optimization decision and adding optimization decision random number can make the algorithm jump out of the local optimal solution and get the global optimum so as to improve the accuracy of the algorithm. Then the random demand is used to optimize the enterprise financial risk management model. Experiments show that the random demand, which has better convergence accuracy and convergence speed, can achieve a better optimization effect on the enterprise financial risk management model, reduce the risks, and increase the income.
