  • Case studies of Chinese firms experiences with intellectual property-conditioned state incentives   Order a copy of this article
    by Dan Prud'homme, Xingle Long 
    Abstract: This paper explores how useful Chinas intellectual property (IP)-conditioned state incentives especially patent-related subsidies/awards and tax incentives tied to patenting requirements are to improving Chinese firms competitiveness. Based upon three short case studies derived from interviews with Chinese firms in Jiangsu province we reach several tentative conclusions. First, the incentives provide external resources that can directly help firms improve their competitiveness and more indirectly support strategic distribution of internal resources. Second, the incentives may be particularly useful for firms facing significant patent thickets because they can help strengthen their patent portfolios, which improves the firms bargaining power. Third, despite having some positive impacts, the incentives are not always sufficiently funded or accessible enough in order to make them optimal industrial policy instruments. Fourth, the state sometimes precludes the incentives from covering the costs of in-licensing foreign-owned IP and technology, which can be counterproductive to the states ultimate objective of helping Chinese firms catch up with foreign incumbents. Overall, we conclude Jiangsus IP-conditioned state incentives are somewhat useful to helping indigenous firms improve their competitiveness, but could even more smartly formulated and administered.

  • Ensuring Quality in ERP Implementations through Testing Components - An ISM Approach   Order a copy of this article
    by Shruti Nagpal, Sunil Kumar Khatri, Ashok Kumar 
    Abstract: Enterprise Resource Planning (ERP) systems are software implementations in which the entire or most of the organizations processes are brought under a uniform product suite. These ERP systems are mostly off-the-shelf vendor-specific ERP systems that are customized to the organizations specific needs. Thus, ERP implementations encompass not only software development which is mostly categorized as customization but also configuration of the organizations systems. If the organization is implementing a pre-tested ERP system, then why does the question still arise about ERP failures and/or ERP implementations grossly going beyond time and budget calculations. Previous research has paid focus on Critical Success Factors for ERP implementations. The present research goes beyond discovering the Critical Success Factors for ERP implementations and delves into factors that would help in ensuring overall quality of ERP implementations. Since, ERP systems themselves are implemented with the main objective of improving the overall efficiency and hence productivity of the organization, so the quality of ERP implementations itself becomes an aspect of paramount importance. The quality of ERP implementations has received lackadaisical research support. Nagpal et al. (2015) prioritized and ranked the testing components with the help of Analytic Hierarchy Process (AHP). The present study further explores the interrelationships between the testing components by utilizing the Interpretive Structural Modeling (ISM) and extends it by using Total Interpretive Structural Modeling and cross-impact matrix-multiplication (MICMAC) Approach.

  • TOWARD A REVISED THEORY OF TECHNOLOGY CYCLE FOR KNOWLEDGE-BASED TECHNOLOGIES - An Empirical Analysis of Microprocessor, Mobile Cellular, and Genome Sequencing Technologies-   Order a copy of this article
    by Yu Sang Chang 
    Abstract: Does the innovation process of knowledge-based technologies differ from the process of industrial technologies? Do knowledge-based technologies need a new theory of technology cycle? These are the two key questions that will be examined in this paper. This paper will examine the characteristics of radical innovation from a longitudinal study of knowledge-based technologies: genome sequencing, mobile cellular, and microprocessor technologies. Our findings are then compared to the similar research findings reported earlier from industrial technologies such as glass and cement technologies. We found that the role of radical innovation in knowledge-based technologies has become so critical that it deserves a new designation of super radical innovation. Finally, a revised theory of technology cycle incorporating the concept of super radical innovation for the knowledge-based technologies will be developed.

    by Eyup Calik, Fethi Calisir 
    Abstract: Firms must develop and improve their innovation capabilities to gain competitive advantage. There are many innovation models including components and their relationships in the literature. This study evaluates, based on a system approach, an innovation model with three basic components: innovation input, innovation process, and innovation output. The main objective of this study is to show the relationships among the innovation components. Structural equation modelling was performed to test the relationships by employing data from 309 companies in Turkey. Results show the innovation input components affect positively the innovation process. Moreover, the innovation process has a positive influence on the innovation output. It also mediates the relationship between the innovation input components and the innovation output. This model can be evaluated by innovation leaders to gain an overview of their firms innovation path and used by researchers to compare it with other innovation models.

  • Efficiency assessment of photovoltaic power stations using two-stage data envelopment analysis: case study in Inner Mongolia, China   Order a copy of this article
    by Yunna Wu, Xiaokun Sun, Chuanbo Xu, Xinli Xiao, Zhiming Lu 
    Abstract: The photovoltaic(PV) power generation industry has developed rapidly in China in recent years. However, given the rare research on the efficiency of Chinas photovoltaic power stations (PVPS), this paper takes 33 PVPS in Inner Mongolia as samples, and uses a two-stage model to analyze their power generation efficiency. In the first stage, the efficiency scores of PVPS are calculated by data envelopment analysis method, and the robustness of the efficiency scores is verified by sensitivity analysis. In the second stage, the relationship between the efficiency scores and the environment variables is studied using the Tobit regression. The results show that the age, solar energy curtailment rate, environmental temperature, atmospheric dustfall and ownership of PVPS have influence on productive efficiency in varying degrees. The results can help the stakeholders in the PV power generation industry to optimize operational strategies, make related operational policies and provide a useful dataset for comparative studies.

  • Does natural language perform better than formal systems? Results from a fuzzy agent-based model   Order a copy of this article
    by Cristina Ponsiglione 
    Abstract: The objective of the paper is to present the use of the March model on exploration and exploitation in organizational learning (1991) as a virtual laboratory of organizational design. The virtual laboratory, named CLOD (Computational Laboratory of Organizational Design), will be devoted to exploring the behaviour of organizational learning and evaluation systems under different external and internal conditions. The contribution of the article would be twofold: firstly, the cellular automata model of March is transposed in an agent-based environment and then extended to be used as a virtual lab supporting organizational design; secondly, a fuzzy version of the model is proposed in order to analyse, through generative experiments, the differences between crisp and fuzzy organizational learning approaches to environmental complexity.

  • Diffusion of Innovative Technology in U.S. Oil and Gas Industry- An Empirical Study   Order a copy of this article
    by Ronald Salazar, Rupak Rauniar, Carlo Mora 
    Abstract: This paper presents the results of our attempt to validate the theory of diffusion of innovation (Rogers 1962, 2003) employing survey methodology. We find that complexity, trialability, and observability exhibited correlation with innovation diffusion while the impact of remaining constructs are not supported. Innovation and technology have been long considered important drivers of organizational success. Once a decision to acquire and adopt a new technology has been made, a successful transfer of such technology within the organization is often measured by the extent of diffusion of the newly adopted technology. Understanding the drivers of successful diffusion of innovative technologies in the US Oil and Gas (O&G) industry is critical since the industry overall is facing economic hardship and actively seeking operational efficiency and excellence in exploration, production, and distribution costs. Rogers (1962, 2003) theory of Diffusion of Innovation or DoI is used in identifying and operationalizing key variables that affect diffusion of innovation. This paper elucidates diffusion of innovation (DOI) in the U.S. O & G industry. It broadens understanding of how the industry has responded to the presence of multiple, important new technologies and how the diffusion of these technologies can be explained by the application of the DOI model. Using primary data, the current study empirically tests DoI in the context of todays US O&G industry. The contribution of the current study to both researchers and practitioners, limitations, as well as suggestions for future studies are also provided.

  • An Efficiency Analysis of Turkish Railways Using Data Envelopment Analysis - Comparison study   Order a copy of this article
    by Ghanem Osman, Li Xuemei 
    Abstract: The aim of this study is to examine whether Turkey as a candidate for the EU membership, utilizes its railway performance. To investigate the Turkish railways efficiency and identify its current situation, the efficiency of Turkish and EU railway are evaluated by applying DEA output-oriented model of CRS (CCR) and VRS (BCC) analysis. In this research, each country is considered as a decision-making unit called DMU; every efficiency country is calculated and compared to the other country. In conducted analysis, there are five inputs taken into consideration, along with two outputs distinguished by two forms of transport: passengers and freight transport. The evidence from this study seems to suggest that the technical efficiency of Turkish railway equals 0.89, and sale efficiency equals 0.98, indicating obtained suitability in inputs and outputs for reaching the efficiency boundary.

    by Daniel Urueta-Hinojosa, Pedro Lara-Velázquez, Miguel Gutiérrez-Andrade, Sergio De-los-Cobos-Silva, Eric Rincón-García, Román Mora-Gutiérrez, Antonin Ponsich 
    Abstract: Coloring problems can model different problems in the real world. Among the problems of coloring we have the Soft Graph Coloring, in which, given anundirected complete graph with weights on its edges (penalizations), we search to reduce the sum of the penalizations between two vertices painted with the same color. Also, we have the classic coloring problems, which includes: minimal, weak, equitable and robust coloring. The objective of this work is to develop an integrativemodel that solves the classic coloring problems through the Soft Graph Coloring model and GRASP metaheuristic algorithm, using particular instances to each colororing problem that allow to compare how efficient the proposed model is; so will be possible to observe the behaviour of Soft Graph Coloringsolving other types of coloring problems.

    Abstract: Different aspects have enhanced the development of scientific research in business and management in Chile. The aim of this paper is to analyse the characterization of this scientific evolution. The method used is a Bibliometric analysis. Our sample examines any paper published between 1991 and 2015 in the Web of Science (WoS) database in the area of business and management. The main results show that the publications have had a significant increase. In the last 5 years (period 2011-2015) 30% more has been published than in 20 years (period 1991-2010). Scientific productivity increase may be related, among other factors: to the efforts of the Chilean universities that reward and incentivize publications in WoS; the participation of academics in competitive grants (Fondecyt); and international accreditations that demand more productive universities in terms of research. The results of the study could be interesting for universities from developing countries wishing to generate policies to increase the productivity in the areas of business and management.

    Abstract: This paper features a two-country study on digitalisation: Australia and Finland. The empirical data was acquired from the national accounts for 19952015 in Australia and for 19982012 in Finland. This data was averaged for a cross-sectional comparison of industries and then for the two countries. Different industries advancement in digitalisation seems to follow approximately the same pacing in both countries. Financial and insurance services, telecommunications and media, and professional, technical and scientific services are the most active digitalisers. The empirical testing of the a priori assumption that digitalisation over a long period of time leads to greater productivity shows that the observed correlation between ICT investment and productivity is weak. The results partly confirm Solows productivity paradox.

  • Evaluation of Development Level and Economic Contribution Ratio of Science and Technology Innovation in Eastern China   Order a copy of this article
    by Mingran Wu, Min Zhao, Zhaodan Wu 
    Abstract: Scientific and technological (S&T) innovation is the key driving factor for economic development and social progress. The eastern part of China is the barycenter of the Chinese economic map and has one of the highest economic growth rates in the world. Eastern Chinas growth pattern has a tremendous impact on the structure of world economy. The paper evaluates the development level and economic contribution ratio of S&T innovation in all provincial regions of eastern China from 2013 to 2015. The results show that the levels and ratios in regions have significant differences. Moreover, the current economic growth primarily relies on capital investment, and the contributions of S&T are relatively limited. Thus, in future developments, the government needs to emphasize S&T innovation as a key driver of economic growth to ensure the balanced growth of the entire region.

  • Analyzing consumers perception comparatively on hybrid electric according to online comments   Order a copy of this article
    by Jianfeng LI, Mingqiushuo Wei, Jun Zhai 
    Abstract: Hybrid electric vehicles are regarded as an available near-term green solution to reduce the greenhouse gas emission in transportation sector, but they still dont play a dominant role in some auto market. In the view of consumers perception, this paper investigates 1109 online comments to find out the reasons that cause large sale discrepancy. A framework including five aspects and nineteen factors is proposed, which help to analyze the consumers perception on HEVs systematically. In addition, based on that framework, the difference on consumers perception between China and America is investigated comparatively, which is also as a good case on HEVs for some other developing and developed countries. Finally, according to comparative result, three basic strategies, including cannikin strategy, suboptimum strategy and dominant strategy, are brought forward to boost the widespread adoption of HEVs in different markets.

  • A Control Strategy of ES System based on Short Term Wind- PV Power Prediction   Order a copy of this article
    by Huizheng Ji, Dongxiao Niu, Han Wu, Meiqiong Wu, Bingjie Li 
    Abstract: Based on the short term wind and photovoltaic power forecasting, a charge and discharge power control method of energy storage system containing two control coefficients is proposed, which may make the output of the hybrid wind/photovoltaic/energy storage (wind-PV-ES) system furthest matched with the scheduled output. In view of the randomness and uncertainty of wind/PV generation, chance-constrained programming is adopted. This method takes the output of wind-PV-ES in scheduled range and the cost of ES as the objectives, considers the constraints of power output of energy storage equipment and electric quantity, and wields adaptive genetic algorithm (AGA) based on Monte Carlo simulation (MCS) to obtain each time frames charge and discharge power day-ahead. Finally, taking national wind-PV-ES and transmission power station for simulation, this paper compares the effect of tracking scheduled output in fixed coefficients situation and variable coefficients situation. The results verify the feasibility and flexibility of the proposed strategy, which can improve the ability to schedule of hybrid wind-PV-ES system. Furthermore, the results between multi-objective and single-objective optimization in fixed coefficient case indicates that multi-objective optimization is more comprehensive and economy.

  • Heuristic Rule-based Process Discovery Approach from Events Data   Order a copy of this article
    by Hind R’bigui, Chiwoon Cho 
    Abstract: Knowledge management consists of taking data and transforming it into beneficial knowledge in a business environment. Today, large amounts of data related to the execution of business processes called event logs are stored in the information systems. Process mining enables knowledge management by extracting knowledge from these historical event logs. Most organisations seek to understand how their business processes are executed to improve them and survive in todays dynamic business environment. Therefore, several process discovery techniques have been developed in the field of process mining. However, none of the existing algorithms can discover all types of constructs that can exist in an event log in a restricted time. In this paper, we propose a new heuristic rule-based technique that constructs process models and which is capable of handling standard constructs, short loops, invisible tasks, duplicate tasks, and non-free choice constructs. Artificial and real-life data have been used to evaluate the algorithm, and the results demonstrate that the aforementioned characteristics can be discovered correctly.

    Abstract: Distributed storage and processing of dataset of big data have become an integrated component of data science. With the technology progress towards the IoTs, big data becomes more important. Therefore, processing of such data needs utmost concern for the ease of availability and accuracy. Various research has been executed till date for the efficient use of splitting and merging of content in the processing of data. But, somehow they lack in the generation of proper clusters in Hadoop. In this paper, we have shown an efficient approach of using splitting and merging process of data processing. We have used component analysis and hamming distance to generate thee clusters depending on the split values which is novel in this domain of work. The experimented results of our proposed approach provide better efficiency in term of discrete clusters and time consumption.

  • Inclusion of Wikipedia, a language specific knowledge resource to generate and update a synset in WordNet   Order a copy of this article
    by Sunny Rai, Amita Jain, Priyank Pandey 
    Abstract: Lack of competent lexical resources is a ubiquitous fact that negatively affects the development of tools for Natural Language Processing of not so widely spoken languages. Recent advancements in machine readable lexicons creation such as Indo WordNet have significantly contributed in reducing the scarcity of lexicons for Indian languages. However, the coverage of the generated lexicon is a matter of concern. In addition, the cost and time incurred during the process are other limiting factors. The reluctance to adopt an automated approach for a lexicon generation is majorly credited to the poor precision of the generated synsets in the lexicon. The inability to capture meanings limited to a language and incorrect back-translation of gloss or examples in the target language also act as a deterrent. In this paper, we strive to tackle these issues by incorporating languagespecific knowledge resources which enable us to capture the words endemic to a culture or a language. We propose a corpus based approach to automate the process of generation of lexical entries i.e. synsets.We use existing language-specific knowledge resources namely Wikipedia and Wiktionary. We also present a method to update existing synsets in WordNets to include newly coined yet globalized words such as selfie. The inclusion of Wiki features for Hindi visibly improves the process of synset generation along with preserving the authenticity of endemic senses. The experiments performed on a manually created dataset of Hindiwords demonstrate a precision of 81.56% and F-measure of more than 72%.

  • Matches between Network Structure and Competitive Strategies   Order a copy of this article
    by Xuefeng LIU, Ke'nv YU, Xuefeng LIU 
    Abstract: Drawing on social network theory and Porters competitive strategy analysis consistent with extant literature, this study investigates characteristics that leverage the matches between network structure and competitive strategies and explores if the combination of effects can also influence firms performance. Using data from a special unit within Chinese floricultural cluster, we test the interaction effects between network structure (measured by centrality, structural holes and key ties) and competitive strategies (cost leadership strategies and differentiation strategies).Results show that inter-firm networks with a high degree of centrality should be matched with cost leadership strategies. In addition, these findings indicate that key ties, which may affect how firms process non-redundant resources are a great help to execute cost leadership strategies but are detrimental to the effectiveness of differentiation strategies. Managerial implications and directions for future research are discussed.
