    by Myungnam Bae, Jaehak Yu, Inhwan Lee, Yang Sun Lee 
    Abstract: In this paper, we propose a position revision of sensor node that utilizes the geo-spatial information and considers the path-loss factors to reveal the radio propagation loss interfered with the major urban obstacles. First, we measure the propagation path loss about the radio frequencies in the target street of the urban, and define the correlation between the measurements and the geo-spatial characteristics for the street and its surrounding obstacle get from the geographic information system. Secondly, through the use of the correlation, we describes the detailed instruction for required to determine the radio coverage and the reliable deployment plan of the wireless node in the core area of urban. By the consideration of them, we can evaluate the communication reliability below 5dB RMS error. And, our study can be utilized as the way to revise the deployment plan based on the path loss and can be apply to the power conservation stragegy of the entire networks through transmission power adaption that is reconfigure relative to a received power.

  • SaaS level Database Integration in Cloud Environment through Database as a Service   Order a copy of this article
    by Trushna Parida, Sanjukta Pal, Anirban Sarkar 
    Abstract: SaaS level database integration is trends to provide the integrated view of the cloud databases through the services. Till now data collection from the heterogeneous cloud databases through the reusable shared services, within a minimum time span and with the flexible and scalable computational support, are the challenging issues. So, limitations during service level database integration ranges from flexibility, scalability, data availability within less overhead, maximum service reusability as well as data reusability and handling data heterogeneity. For providing the logical integrated view of cloud databases, the most important task is data delivery. This data delivery can be performed through Database as a Service or DBaaS realization in a self-service mode. But, here Application services are considered as the user interface provider to deliver some extra facilities like flexibility, scalability, handling heterogeneity regarding implementation issues. In this paper, a graphical model for SaaS level database integration (SLDI) has been proposed. The proposed model is useful towards realization of various database Integration approaches through services. In this context, several important quality metrics like integration complexity, degree of consistency, degree of availability and degree of partitioning tolerance also have been defined over the proposed model. The proposed model is able to proof the compatibility of CAP theorem through the empirical evaluation. Except those, the proposed database integration approach also able to handle data heterogeneity through service reusability as well as data reusability in presence of scalability, flexibility.

  • Feature Models as Service Contracts in Service Oriented Architecture   Order a copy of this article
    by Akram Kamoun, Mohamed Hadj Kacem, Ahmed Hadj Kacem, Khalil Drira 
    Abstract: The service contract is one of the fundamental design principles in the Service Oriented Architecture (SOA). Its goal is to express the features (e.g., services and capabilities) of Service Providers (SPs) so Service Consumers (SCs) can identify them to communicate correctly. The two most known service contracts in the literature are: WSDL for SOAP and WADL for REST. We identify that these service contracts suffer from several problems (e.g., they only allow expressing a limited set of features). Also, we notice from the literature a lack of service contracts dedicated for SC. In order to overcome these problems, we propose two Features Models (FMs) based on SOA design patterns that can be considered as generic and formal service contracts for SP and SC. We propose extensions to the Feature MetaModel (FMM) and semantic constraints that ensure generating fully functional, valid, customized and consistent SPs and SCs from the proposed FMs.
    Keywords: Service oriented architecture; Service contract; Service provider and service consumer; Software product line; Feature model; Design pattern.

  • Identity Evaluation of Moving Vehicles Tracking using Hue and Slope Value on Wireless Sensor Network   Order a copy of this article
    by Ki-Hong Park, Yoon-Ho Kim 
    Abstract: Moving vehicle detection is a very important task in intelligent transportation system and video surveillance system. In this paper, we proposed the identity evaluation method for checking on whether or not the same vehicle as time progresses. The proposed method is composed of background/foreground, the moving vehicle detection with color-based shadow removal, and the tracking process. To verify the identity evaluation, we adopt the moving vehicle features including the hue value, a slope of moving distance and the movement factor. Some experiments are conducted so as to verify the proposed algorithm, and as a result, the identity evaluation of moving vehicles is well detected and tracked with a unique value of moving vehicle features.

  • The five-year effects of physical activity and sedentary behaviour on chronic disease morbidity of Chinese adults   Order a copy of this article
    by Qing Wei 
    Abstract: Chronic diseases are long-lasting and slow-progressing conditions that can be controlled but not cured. Physical activity and sedentary behaviour are risk factors for the major chronic diseases that account for most deaths in developed countries and are increasing rampantly in newly industrialized nations. In this paper, the five-year effects of physical activity and sedentary behaviour on the morbidity of five kinds of chronic diseases in Chinese adults aged 1855 years are examined using statistical analysis with the China Health and Nutrition Survey data. Cohort study demonstrates that completing more than 280 metabolic equivalent (MET) hours a week of physical activity can significantly reduce the risk of diabetes, whereas having more than 14 hours a week of sedentary behaviour during leisure time can increase the risk of suffering from hypertension, and having more than 28 hours a week can increase the risk of suffering from diabetes.

  • Discovering Objects and Services in Context-aware IoT Environments   Order a copy of this article
    by Wei Wang, Kevin Lee, David Murray, Jian Guo 
    Abstract: The future IoT is expected to connect trillions of objects across infrastructures and domains worldwide. Compared to traditional web applications, the context of objects, such as dynamic object property values, may rapidly change. Browsing web pages with hyperlinks is unsuitable for representing and discovering the dynamic state of objects and services in the IoT, as the dynamic context is less keyword-rich than the relatively static contents on traditional Web pages. This paper reviews state-of-the-art in discovery in the current IoT, and analyzes the constraints. This paper also proposes a discovery mechanism, which is extended from previous work GGIoT. The proposed discovery mechanism is aware of dynamic context change in the IoT, and can improve the discovery process using automation.

  • Analysing Prior Research to Improve Business Performance in the IoT Industry.   Order a copy of this article
    by Soo-Young Kim, Gyu-Don Lee, Sang-Jin Lee 
    Abstract: The development of information and computer technology (ICT) leads to a hyper-connected society in which humans and things are connected to one another over networks. Accordingly, information technology (IT) firms are gradually incorporating Machine to Machine (M2M), the Internet of Things (IoT) and the Internet of Everything (IoE). Under these circumstances, IT firms strive to manage uncertainty and rapidly changing environments and optimise performance. The growing IoT industry forces IT firms to innovate to survive. Therefore, this study attempts to identify the main factors facilitating business performance by analysing prior studies. This study demonstrates that IT firms non-financial performance outweighs their financial performance. In particular, it emphasises that value orientation, adaptive selling behaviour and organisational citizenship behaviour are the key factors influencing the non-financial performance of IT firms. This study reviews the literature on the business performance of IT firms in the IoT industry, which would help researchers studying IoT.
    Keywords: Business Performance; Value Oriented; Adaptive Selling; Transformational Leadership; Organisational Citizenship Behaviour.

  • The Effects of Sign Value of Travel Blogs on Travellers Motivation, Negotiation and Intention to Travel   Order a copy of this article
    by Wee-Kheng Tan, Chia-Yu Kuo 
    Abstract: Sign value is significant in its information multiplier effect. However, few studies on sign value offered by tourism information are available. This study focused on the effect of sign meaning of tourism information provided by travel blogs on leisure negotiation mechanism, i.e. whether sign value assists information seekers to enforce motivation, initiate leisure negotiation to overcome obstacles and contribute to overseas leisure travel intention. Partial least squares analysis showed that sign value enforces motivation and intention but cannot initiate negotiation strategies. The nature of travel blogs is conducive for tourism information to provide sign meaning to the information seekers. This study added to the literature in the behaviour of tourism information search that centred on travel blog and leisure negotiation mechanism, and suggested that destination marketing organisations and bloggers could enhance their offer of service and symbiotic mutualistic relationship by working together to provide sign-rich information to their potential visitors/readers.
    Keywords: travel blog; sign value; information search; leisure negotiation mechanism.

  • Chinese university students perceptions of ecotourism   Order a copy of this article
    by Ming Ming Su, Geoffrey Wall 
    Abstract: The concept and practices of ecotourism have been widely discussed since the term was created. Current understanding of ecotourism has been primarily rooted in western ideology and values. When transported to a different culture, equivalency of meaning is difficult to establish. With a growing interest in ecotourism research and practices in China, scholars have argued that the concept of ecotourism has distinctive connotations in China. Using a questionnaire survey and focus group discussions with university students, it is shown that while an emphasis on natural environments and respect for their use is widely accepted, Chinese informants assigned greater importance to culture, were more inclined to reject a dualism between humans and nature, and gave more priority to health outcomes than is common in the west. On the other hand, they were more tolerant of mass use and were less likely to recognize the need for local benefits and empowerment. This study generates valuable insights on the future development ecotourism in China.

  • An adaptive load management service in federated cloud platforms   Order a copy of this article
    by Peng Xiao, Yongjian Li 
    Abstract: Recently, cloud platforms have become a promising distributed paradigm for providing flexible computing capability to various high-end applications. Unfortunately, traditionally load management service can not meet the requirements of cloud platforms due to its elastic resource provision characteristic, which is especially true in federated clouds. In this paper, we present a novel adaptive load management service which applies the Fuzzy Inference Model to implement the load-dispatching rules. In this way, we can quantitatively describe the highly nonlinear workload patterns through a small number of simple rules and then make robust load-dispatching decisions. Extensive experiments are conducted in a campus-oriented federated cloud platform to investigate the effectiveness and performance of the proposed load management service, and the results indicate that it can precisely capture the runtime characteristics of workloads and significantly improve the performance of load management service in large-scale cloud environments.

  • Interactivity, engagement, trust, purchase intention and word-of-mouth: A moderated mediation study   Order a copy of this article
    by Shu-Hsien Liao, Yu-Chun Chung 
    Abstract: This paper presents a model of influence of interactivity and engagement on hotel customers purchase intention and word-of-mouth by simultaneously including trust as a mediator, analyzes the direct and indirect effects among these constructs, and examines the moderated mediation effect of brand loyalty. In the proposed model, purchase intention and word-of-mouth are indirectly affected by interactivity and engagement respectively in the hospitality industry, via the mediation of trust. Besides, the indirect effect of interactivity on purchase intention, and engagement on word-of-mouth through trust will be stronger with higher brand loyalty than for those with lower brand loyalty. Empirical testing using a survey of 408 Taiwan consumers in hospitality and tourism confirms our hypothesized effects. Finally, managerial implications and limitations of our findings are discussed.

  • Technological Competency Assessment   Order a copy of this article
    by Ercan Oztemel, Semih Ozel 
    Abstract: Technological competency assessment has become one of the most important issues in Small and Medium Sized Enterprises (SMEs), particularly in manufacturing industry. The main motivation for assessing the technological infrastructure of an enterprise as a corporate competency is that it provides a faster and higher quality presentation of products and services through the discovery and utilization of technological knowledge. Since, assessing the technological competency of SMEs will bring about various benefits not only to the respective enterprises but also to fund providers and country as a whole. Competency measurement ad related studies are attracting the attention of the research community day by day. A conceptual model for technology assessment is proposed in this study due to this and respective research attractions. The intention is to make the management of the enterprises to become aware of the technological developments as well as the gaps between the actual enterprise technological suit with the availabilities along this line. The proposed model has four core components that are great importance in defining the technological capability contributing to the technological competency as well as making it easy to measure and perform the relative assessments. Those four concepts are defined as Machinery, IT systems, Manufacturing Support Operations, Storage and Distribution. Note that these components are used to generate a nested assessment model which indicates an evolutionary approach to assess the enterprise technological background against the availabilities in the market. The details of those are explained in the paper.

  • The Relationship between Perceived Moral Intensity and Business Ethical Sensitivity of Chinese Insurance Agents: the Mediating Role of Empathy   Order a copy of this article
    by Na Zhang, Jian Zhang, Jing Wang 
    Abstract: Insurance agents business ethics and social image represent an industrial image for the public. However, previous research on insurance agents has mainly focused on the industrial- and organizational-level; individual-level research on personal insurance agents psychology and behavior, which is the foundation and core of the management of an insurance company, has received the least attention. The present study introduces empathy, a moral emotion, into the issue-contingent model to explore the influence of perceived moral intensity on the business ethical sensitivity of Chinese insurance agents. Through the regression analysis of 417 insurance agents, it is found that perceived moral intensity is a significant positive function of business ethical sensitivity. Furthermore, empathy has a full mediation effect in the relationship between perceived moral intensity and business ethical sensitivity. The integrated model of perceived moral intensity, individuals empathy and business ethical sensitivity makes several contributions to service research and management.
    Keywords: Moral intensity; Business ethical sensitivity; Empathy; Emotional contagion; Perspective taking.

  • A Study on Chinese Peoples Everyday Life Information Seeking: Taking a comparison between web and weibo   Order a copy of this article
    by Fang Xiaoke, Xie Yongxian 
    Abstract: There is a paucity of research on Chinese peoples everyday life information seeking (ELIS), especially investigating the relationships between channel value and user behavior. In this paper, an online survey was conducted to capture the background and behavior data from users who regularly use web and weibo, the most influential Chinese language information acquired channels. The friend-of-a-friend recruitment technique received a total of 136 responses, 129 of which were valid and analyzed to generate both descriptive and inferential statistics. Findings indicate that compared with weibo, web was more frequently used by users, and there was more professional information when seeking the purposeful life information on the web. More than one seeking mode were adopted by people through the two channels, and searching is the most widely adopted mode on the web, while browsing on the weibo. Much information can be obtained through the two channels, however the information types needed were different across gender and education levels on the web and weibo. Notably, variables including web use history, web frequency, and weibo use frequency, among the six user characteristics, had significant relationships with values on the two channels, and the four value stages across variables above and other nominal variables had significant differences on the both channels. The reasons behind the preference, usage, and effectiveness of particular platform for ELIS are a fruitful area for future research.

  • A game theoretical analysis of the going global strategy of Chinese high-speed railway   Order a copy of this article
    by Kefei Zhu 
    Abstract: In this paper, we studied the going global strategy of high-speed railway industry in China. We proposed two game models to analyze the situation faced by the high-speed railway industry in China. We first considered the country selection problem (CS problem) to shed light on the situation when we try to find a right partner to fulfil our going global strategy. Our results showed the conditions that guarantee the going global cooperation becomes a dominant strategy Nash Equilibrium. Then, we considered the product or technology problem (POT problem) to discuss the going global mode, i.e. what we should export to the other country. The results showed that even technology export may generate more payoffs to China, the more likely cooperation mode will be the product export. Based on the results of the paper, some practical suggestions have been made to the going global strategy. As far as we know, this paper is the first paper which studies the going global strategy of Chinese high-speed railway industry by game theory.

  • Impacts of Day Trading on the Intraday Pattern of Market Quality   Order a copy of this article
    by Tsung-yu Hsieh, Ying-Fen Fu, Shih-Ya Ma 
    Abstract: In Taiwans stock market, buying first and selling later, as well as selling first and buying later, are permitted, as of January 1, 2014, and June 30, 2014, respectively. This study investigates day trading stocks (pilot stocks) and nonday trading stocks (control stocks) that appear in the Taiwan 50 index and Taiwan mid-cap 100 index during 20132014, with the goal of investigating the impact of day trading on the intraday pattern of market quality. With a difference analysis and cross-sectional regression analysis, this study reveals insights into a stock market that is populated mainly by individual investors. Prior research into intraday patterns of market quality rarely focused on individual investors. The current study demonstrates that the effective spread of pilot stocks decreases significantly, and trading depth increases significantly, after the implementation of buying first and selling later options. This liquidity increase phenomenon then is offset when the selling first and buying later option is permitted.
    Keywords: Market Quality; Day Trading; Buying First and Selling Later; Selling First and Buying Later; Intraday Pattern.

  • Innovative Behaviour and Performance of Technology-based Knowledge-Intensive Business Service: An empirical study   Order a copy of this article
    by Xavier Amores Bravo, Anna Arbussa, Andrea Bikfalvi, Josep Llach, Marc Saez 
    Abstract: The aim of this paper is to learn more about how technology-based knowledge-intensive business service firms (t-KIBS) innovate. To do so, we examine the range of innovation practices employed by a sample of 50 t-KIBS in Catalonia, Spain and the impact these practices have on innovation and business results. We distinguish between practices widely used among manufacturing and services firms and practices that are more typically used by services. Our results reveal that, on the one hand, practices common to manufacturing and services are significant in explaining improvements in both innovation and financial performance, while on the other hand, innovation patterns and practices that are more often used in services are not significant in explaining either innovative outputs or increases in operational profits and returns. These results are important for refining the design of innovation policies at a regional level in Catalonia, as well as abroad. Further research is needed to establish whether the innovative behaviour of t-KIBS is more akin to that of manufacturing firms than to that of service firms.

    by Hao Zhang, Yan CUI, LIYU ZHU, Qing-xiao Hou 
    Abstract: With the development of society and the advancement of science and technology, Chinese automobile manufacturers are struggling with increasingly intense competition in the market. To earn a place in the industry and improve brand competitiveness, many companies are beginning to focus on the logistics of cost control, such that the whole supply chain cost is at its lowest when the value is at its highest, as this is the key to the future survival and development of China's automobile industry. As an example, this paper uses the container transport of Changan Ford auto parts logistics, and based on the cost analysis derived from the Program Evaluation and Review Technique (PERT), the existing transport process is reengineered. Through the comparison of the costs before and after the transformation and the sensitivity analysis based on the reengineered process, it is determined that the reengineered process is superior to the initial process and exhibits strong practical guiding significance for logistics cost control and the development of China's automobile companies.
    Keywords: transport process optimization; PERT network; logistics cost control.

  • Service Supply Chain Incentive Strategy: From the Perspective of Win-win   Order a copy of this article
    by Weiping Zhu, Hongguang Yao 
    Abstract: Classical principal-agent model based on the hypothesis of decision-maker completely self-interest is the mainstream in classical economics; however it reduces the stability of long-term cooperation and cannot reflect win-win cooperation. The paper introduces principals value parameter reflecting win-win relation into incentive strategy, expands the traditional model, and establishes Service Supply Chain dynamic incentive model from the perspective of win-win. In the new incentive strategy, the paper further considers implicit incentive and service providers opportunism behavior. Research shows that the value preference parameter can effectively coordinate the value relation between service integrator and service provider, motivate service provider to improve productive input and decrease opportunistic behavior; implicit incentive has definite substitute effect on explicit incentive; under the joint effect of explicit and implicit incentives, service provider will keep higher productive input level, and its opportunistic input will be controlled effectively at the same time.

This constant turbulence, combined with rapid changes in the external environment, has forced the business sector to become more agile and flexible. Customers want flexibility so that they can choose specific products and services according to their needs. Therefore, providing flexibility to customers has become a major task for service providers, especially in an online context where competition is fierce and there is no direct interaction with the customer. In literature very little has been written by researchers on this context; therefore, the aim of this study is to design a framework for online marking flexibility. To achieve this objective, a combined method i.e. a mixture of fuzzy theory and qualitative Delphi method has been used with data collected through non-probabilistic sampling methods combined with a survey of experts. The findings of this study can help online service providers to target their customers in online platforms according to their needs and flexibility demands.

  • Examining mobile SNS continuance from a dual perspective of social support and privacy concern   Order a copy of this article
    by Tao Zhou, Zuoning Xu 
    Abstract: Mobile SNS enable users to conduct ubiquitous interactions with their peers and exchange social support conveniently. This may strengthen social relationships and facilitate their continuance. At the same time, users are concerned with their personal information disclosed to the service providers. Integrating both perspectives of social support and privacy concern, this research examined mobile SNS continuance usage. The results indicated that social support, which includes informational support and emotional support, has significant effects on flow and trust. Privacy concern affects privacy risk. Flow, trust and privacy risk determine continuance usage. The results imply that service providers need to build a supportive climate and alleviate privacy concern in order to facilitate users continuance.

  • Social resources and value creation: A consumer perspective   Order a copy of this article
    by Tuan Nguyen 
    Abstract: Consumer role in value creation is recently an emerging theme in service research. In the contemporary networked economy, consumer social resources, specifically social capital and social identity, are opportunely suggested as the determinants of their co-creation that, in turn, presumably cause their perceived value. A survey study with SEM analysis of 439 consumers in health care and education in HCMC, VietNam shows all of 13 hypotheses empirically supported. The finding reinforces that social capital and social identity, as interconnected operant resources, influence both consumer co-creation and perceived value that further affects consumer satisfaction and loyalty. The theoretical and managerial implications of the paper are derived.

    by Olanrewaju Kareem, Olayemi Abdullateef Aliyu, Sany Sanuri Mohd Mokhtar 
    Abstract: In the contemporary business environment technology is vital to an organizations performance. Therefore, in the context of an inbound call centre, this study examines the effect of technology-based customer relationship management (CRM) on employees intention to quit. A cross-sectional research approach was used and data was collected from the Malaysian call centre industry. By using survey data, the conceptualized model was tested through structural equation modelling. The findings revealed that the deployment of state-of-the-art technology based CRM, followed by proper training, could significantly and positively engender employee job satisfaction. Furthermore, qualitative overstretch could be prevented, consequentially resulting in a significant reduction in employees intention to quit. Moreover, this study confirms that technology-based CRM implementations within the call centre industry can be a powerful initiative toward resolving the problem of employees low job satisfaction and intentions to quit. This study recommends ways in which management of call centres might best develop, deploy and assess their technology applications so that employees will be less stressed, more satisfied, and willing to remain with the organization. Areas for future research were also discussed.

  • The Joint Effect of Buyer-Supplier Interaction and Service Complexity on Satisfaction   Order a copy of this article
    by Rafael Teixeira, Ely Paiva, Celso Matos, Patrick Vesel 
    Abstract: This study investigates the influence of interaction frequency between service providers and business-to-business (B2B) buyers on buyer satisfaction, taking into account technological services of varying degrees of complexity. Simply put, interaction frequency is moderated by service complexity. Higher levels of service complexity require more interactions between service providers and B2B buyers so that they can exchange information and prepare for service co-production. Data were collected from 228 B2B buyers of telecommunications services in Brazil. The results show that buyer satisfaction is associated with low and medium levels of service complexity and interaction frequency; however, high levels of these variables were not found.

  • A Novel Approach for Improving Data Locality of MapReduce Applications in Cloud Environment through Intelligent Data Placement   Order a copy of this article
    by Shabeera T P, Madhu Kumar S D 
    Abstract: In this world of big data, hosting storage and analytics as cloud service is extremely relevant. In multi-user environments, there are chances for load imbalance during data placement. MapReduce like frameworks move computation towards data. However, because of load imbalance, some nodes cannot start computation on the node on which data is stored and may be compelled to start computation on some other nodes. This results in deteriorating data locality. In this case, data have to be copied to the computing node. This data transfer increases the job completion time. This paper proposes a data placement policy for clouds in which the data and virtual machines are colocated in the same set of physical servers. The physical servers in the cloud are grouped into partitions created using the minimum spanning tree. Experimental results show that this proposal improves node utilization and reduces execution time over default placement in the cloud environment.

  • Segmenting Indian Shoppers on Mall Attractiveness Factors   Order a copy of this article
    by Sanjeev Prashar, Harvinder Singh, Chandan Parsad, T Sai Vijay 
    Abstract: In the last decade, the retail sector in India has transformed from small shops to modern shopping formats. Shopping malls have mushroomed across the country, especially, in metro cities. These emerging formats have attracted a large number of shoppers as they provide - convenience, large assortment of products, entertainment, safety and reasonably priced goods. The existence of many malls has not only increased competition, but also has confused shoppers regarding the distinctiveness of one shopping mall from another. Therefore, it is highly imperative for mall managers to ascertain features that would differentiate their malls from their competitors. The objective of this paper is to identify the various shopper segments and profile them on the bases of their orientation towards various factors associated with shopping malls. The study adopted hierarchical and K-means clustering techniques. The paper also attempts to distinguish these segments in terms of demographic features. Data was collected using a questionnaire in Indian commercial city of Mumbai. Existing measurement scales were adopted and was pilot-tested to check their validity and reliability. The findings advocated that there exist distinctive shopper segments based on various antecedent factors influencing mall selection. Three cluster groups - Hygienic Experience Seekers, Extended Experience Seekers and Prudent Experience Seekers, exhibited noteworthy differences in demographic characteristics like age, marital status, education qualification, income and gender. Though the first two segments constitute a vast eighty-two per cent of the market, they also differ significantly in terms of their expectations from the malls. Besides profiling these segments, the paper has also identified key mall attractiveness factors that retailers and mall managers must take into account while developing the positioning for their outlets. The findings of this study shall facilitate retailers in preparing differentiation strategies in order to cater to the target segment. Though the study is limited to the city of Mumbai and needs caution in generalizing the findings, this has pertinence in understanding varied shoppers segments in the fastest-growing economy of the world.

  • Implementing Lean Thinking in Software Development A Case Study from India   Order a copy of this article
    by Gopalakrishnan Narayanamurthy, Anand Gurumurthy, Shyam Prasath B 
    Abstract: Implementation of lean thinking (LT) in the service sector has been widely reported. Although few studies describing the application of LT in software development (SD) are available, not many are from an emerging market such as India. Our study addresses this gap by using a single-case study methodology to understand the lean approach adapted by a firm in India to overcome the issues faced in its SD process. Data were collected through direct observation for a period of 1 year. Difficulty in integrating work from various teams, long release cycles for the developed software products, late shipments, quality issues, customers dissatisfaction, and high operational costs were the problems faced by the case company. These problems motivated the case company to adopt LT at the team level by following the scrum process. This study identified how the LT approach guided the case company to achieve responsiveness, regular interaction between employees, involvement of customers, accomplishing targets within the planned timeline and so on. This study helps both academicians and practitioners to understand the approach followed to implement LT in a SD firm in India.

  • RETHINKING THE OLD RESIDENTIAL SECTOR IN THE UAE: A METHODOLOGY FOR SUSTAINABLE RETROFITTING   Order a copy of this article
    by Mohamed Elkaftangui, Basem Eid Mohamed 
    Abstract: The Abu Dhabi Government has recently devised a program to promote sustainability guidelines and regulatory tools within the AEC industry in the UAE. The program; known as Estidama, proposes a set of strategies to ensure sustainable practices from design to operation, and maintenance for all building typologies and communities across the UAE. Currently, the Estidama Design Guidelines have been directed towards new construction of residential and commercial buildings. Nevertheless, it is evident that existing buildings and other facilities should be considered in the future within the programs appraisal, given that they represent a large percentage of Abu Dhabis built environment. This research addresses the status of the existing residential stock in the UAE built environment, which included around 185 000 units by the end of the year 2007, prior to the Estidama initiative. We analyze various contextual characteristics, then propose a methodology to integrate effective sustainable refurbishment strategies to capitalize on the scope of Estidamas guidelines with the aim of potentially including a chapter for buildings overhaul in Abu Dhabi. We strongly believe that this research would be a valuable addition to the Estidama guidelines, and could compliment the Abu Dhabi vision 2030.

    by Vimi Jham, Gunjan Malhotra 
    Abstract: Research in ethical consumerism has concentrated on attempts to either categorize ethical consumers or to uncover their decision-making processes, but to-date there have been few investigations into the key ethical drivers behind the decision-making process. This study attempts to identify these ethical drivers within their particular product groups by means of a survey of self-proclaimed ethical consumers distributed via a questionnaire through face to face interactions. The study analyzes whether ethical decision making is dependent on product attributes or ethical attributes or both . A theoretical framework with hypothesized relationships is developed and tested in order to answer the research question. Data have been collected from195 respondents in beauty and health care sector. The proposed relationships are tested using structural equations modeling. The findings indicate that positive relationships exist between the two exogenous constructs namely product attributes (PA), ethical attributes (EA) and the single endogenous construct while making a decision to buy ethical products (BE). The managerial and academic implications of the results are discussed.

    by Bertha Maya Sopha, Aprilia Hestiani 
    Abstract: This present research seeks to explore SCM practices by Indonesian SMEs and to empirically examine the impact of the SCM practices on firm financial performance. Empirical data was collected in 2013 through a survey using structured face-to-face interview. Thirty-nine SMEs producing food, handicraft, clothing and leather in Yogyakarta, Indonesia, are taken as studied cases. Structural Equation Modelling was applied to test the causation relationship between the SCM practices and the financial performance. Findings generally confirm that SMEs put high importance on operational efficiency particularly high on downstream and less attention on the supplier side, which is consistent with previous studies. The findings also demonstrate the significant positive causal relationship between the SCM practices and the financial performance, implying that the higher implementation level of the SCM practices, the better the financial performance. Customer relationship management, supplier relationship, and information system, are found to be the three most practices which contribute significantly to the firm performance. Potential improvement areas and their associated strategies (e.g., horizontal collaboration and vertical partnership) are also discussed.

  • Monetary Integration in the ASEAN Economic Community Challenge: The Role of the Exchange Rate on Inflation in Indonesia   Order a copy of this article
    by Heru Rahadyan, Alexander Lubis 
    Abstract: The implementation of the ASEAN Economic Community (AEC) in 2015 required some form of monetary integration, such as exchange rate management. This paper investigates the role of the exchange rate on the inflation rate in Indonesia. Using the monthly data series from 1970 to 2015, we find that the nominal exchange rate affects the inflation rate at a low transmission speed rate. However, the exchange rate volatility and depreciation threshold may accelerate the speed of the exchange rates transmission to inflation. Thus, studies with short-lagged variables, or studies in different periods may lead to different findings, as shocks and changes in exchange regimes occur regularly in Indonesia. These findings are important as they imply that Indonesia may fail to reach the aims of the AEC if it fails to coordinate its exchange rate policy with the rest of the AEC.

  • The Challenge of e-Money Adoption for Transportation in Indonesia   Order a copy of this article
    by Amalia E. Maulana, Nova Aryanti 
    Abstract: The use of e-money as a breakthrough and solution for customers will enable a variety of transaction activities. Unfortunately, this product has not yet been adopted until the desired level by the issuers and the government as a policy maker. This study is aimed to find deep insights on different aspects that hamper the adoption of e-money in Indonesia, especially those used for transportation. The observation of customers behaviour was conducted by using marketing ethnographic approach, and it was expected to gain insights about the obstacles. This study shows that the lower Relative Advantage and Compatibility is an aspect that needs to be addressed. The level of observability and operational complexity of e-money at the level of customers is considered high, and the lack of education to the customers, and the lack of customers cooperation in the process of learning of new things can be considered as inhibiting factors. This study finds that the incentives for customers and social influencers are the trigger of penetration that can be improved. The results of this research is expected becoming usable for stakeholders in an effort to increase the use of e-money in the sector of transportation to become more precisely targeted and effective.

    by Agung Iswadi, Alan Owen, Leuserina Garniati, Jito Sugardjito 
    Abstract: Coastal community profiles are usually seen as a dilemmatic condition between poor population with unequal energy provision and traditional livelihoods to meet daily needs and specific areas with substantial marine resources potential. One of the immediate and significant challenges confronted by coastal communities in Indonesia related to food security and direct economic productivity, is access to energy. Marine renewable energy provides opportunities and challenges, not only for national energy production from renewable sources, but also for community development in coastal areas. Three (3) case studies have been performed in three different coastal communities in order to capture actual information regarding coastal community profiles and needs. The investigation in Aceh, West Nusa Tenggara and West Papua found that marine renewable energy could become part of sustainable solutions to promote coastal community development. One of the socio-economic impacts that could be beneficial at community level is job creation that would support regional and national GDP of Indonesia. Therefore, Indonesia should be able to face identified challenges in developing marine energy sector in order to strengthen its position in the ASEAN Economic Community.

  • Assessing an Information System in Mandatory Environment: A Case of a Government Agency in Indonesia   Order a copy of this article
    by Siti Mardiana, Jann Tjakraatmadja, Atik Aprianingsih 
    Abstract: This study aims to develop a conceptual model for assessing an information system in a mandatory environment. An empirical study is conducted to test the validity of the model. The analysis was using SmartPLS due to the abnormality of data distribution and relatively small sample size. The respondents were operators at a government agency who use the system for managing migrant workers data. Even though all indicators for a good model are fulfilled, due to a relatively small sample size, the findings should be used with caution. In this study, social influence is not a good predictor for intention to use while perceived usefulness is. The effect size calculation showed that perceived usefulness has a substantial effect toward intention to use. System usage made a bigger impact on perceived benefits rather than on user satisfaction. The implications are, first, the authority in the agency must promote the usefulness of the system. Second, increasing users intention to use the system will increase system usage that provides benefits for users.

    by Akbar Adhi Utama, Nurbudi Mulyono, Sita Deliyana Firmialy 
    Abstract: To increase the competitiveness of ASEAN economy through AEC (ASEAN Economic Community), the role and strategy of R&D in spending alignment need to be revitalized. An understanding of the current R&D strategy of each AEC member country through the comprehensive analysis of R&D expenditure is also required. This paper addressed the issues of R&D expenditure and intensity in Indonesia that is currently placed at a relatively low position among other ASEAN members. The quantitative method was utilized to achieve the research objectives. The data,obtainedfrom 228 companies ofvarious sectors in Indonesia, were collected and integrated as the empirical basis for testing the hypotheses.The results suggested that although the growth opportunities and leverage have the different effect on R&D intensity, the intensity effect is still very inadequate. Most of companies allocated their R&D investment for internal purposes.They invested R&D expenditures to increase the efficiency of their companies, even it hadlow contribution to their companyvalue.

    Abstract: This study aims to clarify the dominant factors (which can be defined as antecedent factors) influencing the structure choice in the supply chain governance of traders and middlemen of broiler chickens. This study has utilized closed-ended questionnaires with 5-Likert Scale distributed to several traders and middlemen of broiler chickens in the traditional town market in Semarang City of Central Java Province. One hundred and twenty-five copies of the questionnaire were administered to the traders of broiler chickens in these marketplaces: North Johar, Central Johar, South Johar, Bulu, Karangayu, Peterongan, and Jatingaleh. Additional information was collected through follow-up telephone interviews and archive records. Data acquired from the questionnaire were processed using Structural Equation Modelling (SEM). The findings indicate that the transaction cost economy and the collaborative advantage have a significant positive effect on the level of integration; in this case, the effect of the transaction cost economics stronger than that of collaboration advantages. The findings also suggest that the transaction cost economics significantly depends on uncertain conditions between traders and the middlemen; whereas, the collaborative advantage significantly depends on uncertain conditions and collaboration capability.

    by Sonu Rajak, P. Parthiban, R. Dhanalakshmi 
    Abstract: Nowadays, meeting the customers demands in the shortest time and least cost is the most challenging task of maintaining any supply chain. Vehicle Routing Problem (VRP) plays an important role in the logistics. In typical VRP, customers are used to serving as a single depot, but in real-life single depot will not be sufficient to meet the customers demand or customers satisfaction. In this context, this article presents the Multi-Depot Vehicle Routing Problem based on Customers Satisfaction (MDVRPCS). Since MDVRPCS is an NP-hard problem so, Ant Colony Optimization (ACO) has been proposed to solve the MDVRPCS. The proposed algorithms have two phases. The first Phase involves clustering the nodes into a desired number of groups. This has been done by using K-means clustering algorithm. The second Phase involves optimization of routes for each cluster. This is achieved by using ACO. The proposed algorithm has been tested for wellknow problem instances from the literature. The results show that the algorithm is capable of obtaining good optimal solutions.

  • Energy-Efficient Fairness-Aware Memory Access Scheduling   Order a copy of this article
    by Aastha Modgil, Vivek Sehgal, Nitin Chanderwal 
    Abstract: In a chip multiprocessor (CMP) major resource that is being shared among multiple cores is main memory as it is responsible for storing data structures needed for execution of a program. Chip multiprocessor system enables multiple threads to run simultaneously on a chip. Diverse threads running simultaneously on same chip may compete with each other for resources. Because of interference among threads, each thread can experience extremely different memory system performance. If interference among threads is not controlled, then one thread can experience extreme starvation or slowdown while another is unfairly prioritized. Performance, power consumption and capacity are three major factors that affect the design of a memory system. By efficiently reordering concurrent memory requests, power consumption and performance can be improved. Intelligent reordering of memory accesses reduce the number of operations to be performed thereby resulting in decreased average latency and power consumption. This work proposes a memory access scheduler, Energy-Efficient Fairness-Aware Memory Access Scheduling (EEFA) that provides each thread equal opportunity to access memory banks by prioritizing requests generated from reorder buffer head thus ensuring thread fairness. The scheduler exploits bank level parallelism by pre-issuing issuable read commands during drain-write mode. Also, proposed scheduler prioritizes row buffer hit requests, hence reduces average access latency and power consumption. The authors show that Energy-Efficient Fairness-Aware Memory Access Scheduling significantly reduces unfairness among threads and energy consumption in DRAM memory system while also improving performance.

    by Mingjun Xin, Wenfei Liang, Weimin Li 
    Abstract: With the development of the massive amount of Web services, the popular research area is involved with the solution to select the required services according to the personal preference for different users. To solve these urgent problems, a user preference awareness k-neighbor optimized selection algorithm is proposed and designed in this paper. Initially, the potential interest of the user is explored and clustered by using association rules method of data mining technology. At the same time, an expanded LDA model is used to analyze the influence on user preference calculation for different types of services caused from the functional attributes of Web services. Furthermore, the user preference matrix is constructed for service selection in this paper. To improve the accuracy of the service selection result, the ant colony algorithm is modified to optimize the service selection process of K-neighbors in traditional collaborative filtering, while the missing data in the user preference matrix is predicted. Finally, the Web services with personalized user preference are selected for the target user. The experiment shows that our proposed method leads to a higher accuracy and coverage than the traditional Web service selection methods based on the real service set, which is collected from the Programmable Web site under SOA environment.

    by Li Jin, Bai Yu, Cheng Xuhong 
    Abstract: Model transformation methods tend to create many transformation rules, but there is still some redundancy among these transformation rules. Therefore, how to obtain effective transformation rules has become an unsolved important problem. However, current model transformation methods do not focus on these rules. Therefore, we propose a clustering-based method for the selection of transformation rules. The main idea is to classify the target model elements, transform the rules of each class, and finally obtain the appropriate conversion rules via the post-clustering conversion rules. We also present an algorithm to automatically validate the optimal selection of model transformation rules. A motivating example is presented to illustrate our approach. Furthermore, the comparison experiments of these algorithms are conducted, which have proved the effectiveness of the optimal selection method.

    Abstract: To improve the efficiency of selection of resource services and collaboration among them, the business link between resource services is essential for collaborative tasks. Service flow can better describe the business relationship between resource services. Although a workflow model can describe the relationship of resource service sequences (RSSs), it describes the static relationship between resource services and does not reflect the frequency of RSSs in real business. A method of mining frequent RSSs is proposed. First, by analyzing the task-relevance that exists between resource services, an equation is presented to calculate the distances between resource services. Next, for an RSS, the similarities of resource services are measured by the equation to resolve the set of frequent resource service sub-sequences. Finally, an evaluation method of frequent subsequences is proposed. The result of the experiment proves the proposed approach is valid.
    Keywords: collaborative tasks; resource service sequence; mining.

    by Lei Wang, Yibo CHEN, Zhenying ZHAO, Lingxiao ZHAO, Jin LI, Cuimin LI 
    Abstract: As an important branch of wireless sensor network (WSN) in biomedical field, body sensor network (BSN) could remotely monitor a variety of human health data in real time by means of energy-saving and high-accuracy sensor technology, and the sensitive data related to personal privacy should be protected in the process of data transmission.. In this paper, we study a multi-modal health data fusion and analysis method based on the data collected in BSN, in which we design a networking for BSN including Holter sensor, blood pressure sensor and oxygen saturation sensor, and propose a method of myocardial ischemia monitoring and identification based on Bayesian network model and reasoning algorithm. Single-modal Holter monitoring and multi-modal health monitoring were performed on 60 patients with confirmed heart disease, and it was proved that the proposed multi-modal health data fusion and analysis method could effectively improve the detection rate of asymptomatic myocardial ischemia and provide a new auxiliary judgment method for clinical application. Aiming at the requirement of privacy preserving in the data fusion process of wireless body sensor network, a new SMART-RR algorithm is proposed in which an unequal time interval and repetitive data reduction joined factor data fusion strategy is embedded in the algorithm using the characteristics that human health data is cycle repeatability and redundancy. Simulation results show that the SMART-RR is an energy-saving privacy preserving data fusion algorithm with small data communications, high privacy protection and accuracy, and has certain application value in human health signs oriented data acquisition of wireless body sensor network domain.

    by Taiqi Wang, Ting He, Yanjiang Cheng 
    Abstract: After-sales service plays an increasingly vital role in home appliance enterprises. Current research related to after-sales service for home appliance mainly focuses on qualitative analysis while not paying more attention to quantitative analysis. In addition, the importance of each node should be distinguished. To solve the two issues, a customer satisfaction-oriented after-sales service index system which can evaluate the quality of after-sales service nodes is presented based on customer satisfaction framework, and the key indexes with crucial influences on customer satisfaction are selected by association rule algorithm. The significance test verifies the effectiveness of the mining results. Besides, the importance of each key node is analyzed by random forest. Furthermore, the quantitative analysis of the key nodes is performed by multiple linear regression, and the moderating effect of consumption level is verified. Finally, Kano theory and prospect theory are employed to explain the results, and optimization strategies are put forward.
