TL;DR: The concept of Corporate Social Responsibility (CSR) has been controversially discussed for over 50 years as mentioned in this paper and a wide variety of definitions and understandings of CSR have been developed throughout the decades.
Abstract: The concept of Corporate Social Responsibility (CSR) has been controversially discussed for over 50 years. Consequently, a wide variety of definitions and understandings of CSR have been developed throughout the decades. That has made it increasingly hard, or not to say impossible, to agree on a common perception of CSR. Concerning the various notions of CSR, four core controversies can be identified which revolve around certain elements of CSR: First of all, there is the underlying question if CSR is the business of business or if it is none of its business as Friedman has famously argued. Second, should CSR contain legal obligations or is it a purely voluntary concept and, thus, ethical in nature? Strongly connected to that is the third controversy on whether CSR should be self-serving or if it has to be purely altruistic. Finally, there is widespread disagreement on the scope of CSR. Does it have a local, community-oriented focus or should it address concerns of a wider geographical scope? These controversies are analyzed and discussed here with the aim of developing a definition of CSR that does not remain confined to the academic world.

TL;DR: In this paper, the role of e-governance in improving service delivery by altering the principal-agent relationship is discussed and a survey is presented that seeks to test the role and benefits of egovernance.
Abstract: Using ICT in the form of e-governance could yield great benefits in the reform and modernization of the public sector. The experience of e-governance in a number of developed and developing countries has shown that ICT can be a tool for greater service delivery with the goal of improving service quality. E-governance can also promote ‘good govern-ance’, that is, greater civic engagement can increase opportunities for direct representation and voice, and support for increased democracy. This paper discusses and presents the survey findings that seek to test the role of e-governance in improving service delivery by altering the principal-agent relationship. It further seeks to elucidate the quality aspects of public service. Policy recommendations to achieve the benefits of e-governance in Fiji are presented. Strong leadership is required to implement e-governance to capture and internalize the benefits of quality services and satisfied customers.

TL;DR: This paper examined the perceived impacts of tourism on the lives of people from a small New England town and found that most people perceive both positive and negative impacts of tourists and do not want to change their town for increased tourism development even if it results in increased revenue.
Abstract: This study examined the perceived impacts of tourism on the lives of people from a small New England town. Twenty seven in-depth unstructured interviews were conducted. The study found that most people perceive both positive and negative impacts of tourism and do not want to change their town for increased tourism development even if it results in increased revenue. People recognized tourism’s benefit to the town’s economy but less so to their economic situation. Working locals expressed worry regarding the town’s gradually polarized economy and divided social classes and regard tourism as one of the causes. Wealthier members generally view tourism at its present level as beneficial. For further tourism development Peterborough’ population will need to solve this dilemma.

TL;DR: Wang et al. as discussed by the authors used the extended Model of Internet Commerce Adoption (eMICA) to evaluate the web-site performance of travel agencies in China, with some modifications of the model for the purpose of the study.
Abstract: Recent developments in information technologies (ITs), in particular the popularity of the Internet in the early 1990s, have changed the way that tourism businesses communicate with its customers and the way that promotion and sales of tourism products are conducted. Travel agencies with established websites are in a position to undertake productive marketing activities. This paper uses the extended Model of Internet Commerce Adoption (eMICA) to evaluate the web-site performance of travel agencies in China, with some modifications of the model for the purpose of the study. The results showed that travel agencies in China were not utilizing the Internet to its full potential, particularly in terms of marketing using its websites. Suggestions and recommendations are also provided based on the findings of this re-search.

TL;DR: In this article, the authors employed a questionnaire method to examine flight attendants' feelings about emotional labor, the status of their emotional exhaustion, and the relationship between emotional labor and emotional exhaustion.
Abstract: Few research studies have discussed the two variables of emotional labor and emotional exhaustion, and even fewer have examined flight attendants as the research subject. The current study employed a questionnaire method to examine 353 Taiwanese flight attendants’ feelings about emotional labor, the status of their emotional exhaustion, and the relationship between emotional labor and emotional exhaustion. The research results indicate that: 1) while the degree of emotional labor operating on female flight attendants is on the medium to high side, the attendants’ perception of emotional exhaustion is only medium; 2) female flight attendants’ emotional labor has a significant positive correlation with their emotional exhaustion; and 3) among the perspectives of emotional labor, the qualities of “deep emotional masking” and “multiformity” have a significant predictive effect on emotional exhaustion.

TL;DR: In this paper, the authors explored the problems facing small and medium size contractors in Swaziland and highlighted the current government initiatives that had been put in place to address the challenges and problems in order to ensure that contractors are successful.
Abstract: The paper explores the problems facing Small and Medium Size Contractors in Swaziland. The construction sector in Swaziland is not only a significant source of direct employment but also a sector which contributes, through its wide range of projects and operations. The paper will also look at the current government initiatives that had been put in place to address the challenges and problems in order to ensure that contractors are successful. There is a high failure rate among small and medium size contractors in Swaziland. These contractors fail for a variety of reasons ranging from lack of adequate capacity to handle the uniqueness, complexity and risks in contracting, lack of effective management, lack of business management, poor record keeping and inadequate technical, financial and contract managerial skills. Drawing on research on small and medium size contractors, the paper used both secondary and primary litera-ture. 100 questionnaires were distributed to different role players in the construction sector in Swaziland. The response rate was eighty seven (87) percent. The paper reveals that the most problems facing small and medium size contractors in Swaziland is lack of access to finance and late payment by government. The paper closes with recommendations and key lessons for the future.

TL;DR: In this article, a nonparametric model for assessing the credit risk of credit default swaps (CDSs) is proposed, based on the structural approach pioneered by Merton [1] as regards the independent variables.
Abstract: This paper provides a methodology for valuing credi t default swaps ( CDS ). In these financial instruments a sequence of payments is promised in return for protection again st the credit losses in the event of default. Given the widespread use of credit default swaps, one major concern is wheth er the credit risk has been priced accurately. Cred it risk assessment of counterparty is an area of renewed interest due to the present financial crises. This article proposes a non parametric model for es timating pricing of the CDS, using learning network s, based on the structural approach pioneered by Merton [1] as regards the independent variables; he proposed a model for assessing the credit risk of a company by characteriz ing the company’s equity as a call option on its as sets. The model that we are introducing turns out peculiar not only for the use of the neural network, but also for th e use of the implied volatility of one-year options written on the share s of the analyzed companies, instead of historical volatility: this leads to a higher capability of getting the signals launched by the market about the future creditworthiness of the firm (historic volatility, being a medium value, brings in tempora l lags in the evaluation ). Besides, our analysis differs from the structural approach for the fact that it considers the 30-month mean-reverting historical series for CDS spre ads, and this turns out to be one of the main advantages of our f orward-looking model.

TL;DR: In this paper, the authors explored the structure of services processes using a database of 168 service processes that existed within a wide range of enterprises and suggested that applications within service science are not limited to the service industry and that service processes have many similar characteristics.
Abstract: The structure of services processes was explored using a database of 168 service processes that existed within a wide range of enterprises. The results indicate that applications within service science are not limited to the service industry and that service processes have many similar characteristics. The similarities exist across industry sectors (i.e., manu-facturing, service), customer types (i.e., internal, external) and enterprise size (large, SME). A few differences exist and their importance is discussed. It is suggested that an important field within the multidisciplinary umbrella of service science is organizational behavior.

TL;DR: In this article, the authors investigated the extent to which male and female employees of a University differ in various attributes and attitudes and in the level of satisfaction with the type of work they do, and further established factors that might help explain these differences.
Abstract: The study investigated the extent to which male and female employees of a University differ in various attributes and attitudes and in the level of satisfaction with the type of work they do, and further established factors that might help explain these differences. A stratified random sample of 360 academic and administrative staff of the University of Botswana was collected. Findings indicate that differences between males and females in the level of satisfaction were due to certain negative work experiences such as gender discrimination, tribalism and racism, nepotism and favoritism, and due to certain sources of stress from the immediate supervisor, demands of work on private life and from domestic responsibilities. These negative experiences contributed to lower levels of satisfaction among women than among men. Considering all factors that might explain different job satisfaction among employees at a university, five attributes stood out as significant, namely: belonging to an older age group; understanding the competing demands of teaching and research responsibilities; taking advantage of technological advancement at work; perceiving equity in the distri-bution of the workload; feeling that there was always enough to do at work.

TL;DR: In this article, the authors investigated the moderating roles of customer satisfaction and advertising spending on the service operation efficiency (SOE) and profit relationship and found that customer satisfaction is positively associated with a firm's profit.
Abstract: Service-profit chain (SPC) is a powerful tool for evaluating the relationship between the degree of service effort and profit. This framework has been empirically tested in the banking, hospital, retail, and other brick and mortar service verticals. This paper extends the applicability of SPC to Internet-based businesses. The paper also investigates the moderating roles of customer satisfaction and advertising spending on the service operation efficiency (SOE) and profit relationship. Analysis of U.S. Internet service providers during a seven year period from 2000 to 2006 indicates that service operations efficiency is positively associated with a firm’s profit. However, the customer satisfaction and adver-tising spending constructs are negative moderators of the relationship between service operations efficiency and profit.

TL;DR: In this article, the authors consider the changing cultural requirements to support the rise of improvisational working practices within the UK financial services sector and report on some of the outcomes of a study encompassing over 100 hours of interviews, together with a variety of other primary and secondary data.
Abstract: This paper considers certain aspects of a four-year program of research, and addresses the changing cultural requirements to support the rise of improvisational working practices within the UK financial services sector. Specifically, it reports on some of the outcomes of a study encompassing over 100 hours of interviews, together with a variety of other primary and secondary data. The outcomes of the full study are documented elsewhere, and they identify a number of key factors that contribute to the successful use and control of improvisational working practices. One of these factors is a supportive organizational culture, and this specific area is dealt with in this paper. A particular focus is how the sample of organizations has attempted to identify and create supportive cultural conditions for improvisational work to take place. In order to bring clarity to the outcomes of this study, a matrix of the case study organizations is also offered, which segregates those organizations according to their cultural support for improvisation and apparent improvisation effectiveness. Some comment on the current difficulties in the Financial Services sector has also been included, as it could be argued that improvisation may have contributed to shortcomings in control processes by members of that sector.

TL;DR: In this article, a regression model of real estate price with relevant economic variables, and an econometric model to measure real estate's speculative bubble is presented, and the authors conclude that globally there is no bubble in Chongqing (but on the edge of bubble).
Abstract: The paper analyses the causes of the bubble of the real estate, then elaborates real estate bubble theory based on specu-lation. This paper establishes a regression model of real estate’s price with relevant economic variables, and builds the econometric model to measure real estate’s speculative bubble. In application of the model for empirical research on real estate’s speculative bubble of Chongqing, the paper concludes that globally there is no bubble in Chongqing (but on the edge of bubble). Finally, by analyzing the common points about the existence of bubble, the paper indicates that real estate’s investment and macro-economic indexes are disjointed, and thus the investment is excessive, which can in turn corroborate the conclusions obtained by the measuring model.

TL;DR: A personalized recommendation algorithm based on Associative Sets is proposed in this paper, which uses frequent item sets to filter out noise data, and makes recommendations according to users’ real preferences, so as to enhance the accuracy of recommending results.
Abstract: During the process of personalized recommendation, some items evaluated by users are performed by accident, in other words, they have little correlation with users’ real preferences. These irrelevant items are equal to noise data, and often interfere with the effectiveness of collaborative filtering. A personalized recommendation algorithm based on Associative Sets is proposed in this paper to solve this problem. It uses frequent item sets to filter out noise data, and makes recommendations according to users’ real preferences, so as to enhance the accuracy of recommending results. Test results have proved the superiority of this algorithm.

TL;DR: In this article, the authors examined the key issues on system decoupling in service operations of mass customization by conducting a case study in catering services and proposed a judgment-matrix-based model on how to make the decoupled decisions in balancing the multiple operation objectives.
Abstract: The paper examines the key issues on system decoupling in service operations of mass customization by conducting a case study in catering services. It firstly justifies the effectiveness of applying concept of mass customization into service system decoupling to deal with the operation dilemma and then reveals the nature of decoupling decisions for mass customization purpose after discussions on the importance of modularization and the role of technologies including IT in the decoupling process. Based on these analyses, a Judgment-Matrix-based model on how to make the decoupling decisions in balancing the multiple operation objectives is then proposed and further research directions are finally suggested.

TL;DR: The authors examines the perception of small and medium enterprises (SMEs) in juxtaposition to the macro-regional level of tourism development as lead by the Blackstone Valley Tourism Council (BVTC).
Abstract: The Blackstone Valley Tourism Council (BVTC), a state designated council to promote tourism in the Blackstone Valley, Rhode Island, has led tourism development efforts for two decades to revitalize the economics and livability of place. This study examines the perception of small and medium enterprises (SMEs) in juxtaposition to the macro-regional level of tourism development as lead by the BVTC. Local SMEs foresee business opportunities via tourism, yet often do not fully recognize their potential role within it. Local government and the notion of civic tourism are also examined to further understand this gap. The study concludes that local community involvement still remains in the realm of participation rather than empowerment. Thus, the BVTC is being sought for a more innovative and strategic role to develop and manage tourism assets instead of the implementer role traditional tourism organizations engage in.

TL;DR: The deficiencies of current access control techniques in solving the problems of manufacturing process access conflict in networked manufacturing environment were analyzed and an improved access control model was constructed, and the access control models based on manufacture tasks, roles and time limits and the relationships among the ele-ments were defined.
Abstract: The deficiencies of current access control techniques in solving the problems of manufacturing process access conflict in networked manufacturing environment were analyzed. An information model of manufacturing process was con-structed, and a case XML Schema of manufacturing task model was given. Based on the characteristic analysis of the access control for the information model, an improved access control model of manufacturing process was constructed, and the access control model based on manufacture tasks, roles and time limits and the relationships among the ele-ments were defined. The implementation mechanisms for access control model were analyzed, in which the access case matching strategy based on manufacture tasks and time limits, the authorization assignment mechanism based on manufacture tasks, roles, correlation degrees and time limits, XML based access control for transaction security and integrity were included. And the two-level detection architecture of transaction conflict was designed to find the con-flicts both in application and in the database. Finally the prototype system was developed based on these principles. Feasibility and effectiveness of the method were verified by an enterprise application.

TL;DR: In this article, a new evaluation index system for ULC evaluation is set up which contains factors that reflect the market supply and demand, economic development and transportation accessibility.
Abstract: Urban Logistics Infrastructure (ULI) is an important area of urban competition capability. The connotation of Urban Logistics Capability (ULC) is analyzed in this paper. Compared with the extensive research on ULC in developed world, empirical work is still rare in China. In this paper the theory of ULC is firstly overviewed. Then a new evaluation index system for ULC evaluation is set up which contains factors that reflect the market supply and demand, economic devel-opment and transportation accessibility. Secondly, an empirical study is carried out by using Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA) method to classify ULC into 3 clusters for 30 cities in Peo-ple's Republic of China. Thirdly, according to the characteristics of the 3 clusters, suggestions are proposed for im-proving their ULI. Finally, after comparing different ULC of 30 cities in People's Republic of China, this paper focuses on that different logistics infrastructure including Hub, Central Distribution Center & Cross Docking Center, Regional Distribution Center or Distribution Center should be build reasonably in order to meet the customer’s requirement in the 3 different cluster cities.

TL;DR: A virtualization-based service system development method is proposed that will auto-match and dispatch task to the component to build a real-world service system.
Abstract: Amazon and Taobao publish product introduction online for customers’ personal choice and become the successful examples of modern service based on information and communication technologies. However, if they want to achieve a complex service through composing some simple services, the research of service composition platform is still rudi-mental. In order to achieve this goal, a virtualization-based service system development method is proposed. The service elements are described standardized as service component at first. Then the service component is virtualized to be a web service and is deployed on a service platform, which is similar to Amazon. Customers put forward their demands on this platform and the platform will auto-match and dispatch task to the component to build a real-world service system. Finally, an application in ocean logistics service is briefly introduced.

TL;DR: This paper examined narratives relating to the development of National Geo Information Infrastructures (NGII) in ethnographic research on a Dutch NGII project which was monitored throughout its course.
Abstract: This paper examines narratives relating to the development of National Geo Information Infrastructures (NGII) in ethnographic research on a Dutch NGII project which was monitored throughout its course. We used an approach which focuses on narratives concerning the environment, groups and practice to elicit sense-making processes. We assert that narratives are relatively fixed and that they only change under specific circumstances. Moreover, the fixing of or change in narratives takes place in practice, so our research approach aimed at analysing narratives of practice, which we label ‘storyboards’. For this purpose, project meetings and conferences were observed, key persons both within and outside the project environment were interviewed, and an analysis of relevant documents and video footage was undertaken. Storyboards are created by actors as a result of day-to-day challenges related to project goals, technology and infrastructure. In our research we found that these storyboards occur as vicious circles from which actors cannot escape. In the specific case analysed, our interpretation of the narrative storyboards suggested that these vicious circles are caused by the inability of project participants to distinguish between infrastructure and innovation requirements in their daily work.

TL;DR: The results show that, combining collaborative filtering technology with FCA in a recommendation system can get better users’ satisfaction.
Abstract: With the advance of information technology, people could retrieve and manage their information more easily. However, the information users are still confused of information overloading problem. The recommendation system is designed based on personal preferences. It can recommend the fittest information to users, and it would help users to obtain in-formation more conveniently and quickly. In our research, we design a recommendation system based on personal ontology and collaborative filtering technologies. Personal ontology is constructed by Formal Concept Analysis (FCA) algorithm and the collaborative filtering is design based on ontology similarity comparison among users. In order to evaluate the performance of our recommendation system, we have conducted an experiment to estimate the users’ satisfaction of our experiment system. The results show that, combining collaborative filtering technology with FCA in a recommendation system can get better users’ satisfaction.

TL;DR: In this article, the use of knowledge for innovation has been analyzed from an individual organization point of view so that contextual elements of a knowledge in-novative organization can be identified more precisely along with the institutional implications.
Abstract: The term ‘knowledge’ is getting increased importance as the economy is becoming progressively knowledge intensive. Contemporary view of innovation management is acknowledging knowledge as the most effective source of innovation. Success of the business depends on how successfully knowledge is used for innovation. As a result, organizations are increasingly embracing knowledge strategy for their innovation scheme. Incorporating knowledge in the innovation process; building innovative capabilities and identifying essential features of a knowledge innovative organization are the key concerns of this study. Knowledge is a context specific notion. In this case study, the use of knowledge for innovation has been analyzed from an individual organization point of view so that contextual elements of a knowledge in-novative organization can be identified more precisely along with the institutional implications. Thus, this article would be able to provide a good number of meaningful indications in using knowledge for innovation; it would also shed light on constant capability building for innovation; nurturing of creativity and developing of knowledge infrastructure of a knowledge innovative organization. In addition, this study will be revealing the true nature of knowledge strategy and its application in the context of a developing country.

TL;DR: A U-shaped production line with multiple machines and multiple workers is considered under carousel allocation in which all workers take charge of all machines in the same order and the overall cycle time changes periodically.
Abstract: A U-shaped production line with multiple machines and multiple workers is considered under carousel allocation in which all workers take charge of all machines in the same order. Nakade and Ohno (2003) show that, when the processing, operation and walking times are constant, the overall cycle time, which is a time interval between successive outputs of finished goods, is the greatest value of the maximal sum of the processing and operation times among machines and the time required for a worker to operate and walk around the production line without waiting for processing divided by the number of workers. In this paper, it is considered that operation times at each machine may be different between workers. If processing time is short, it is expected that the overall cycle time will be equal to the time for a worker to operate and walk around the line divided by the number of workers. However, under some specified cases, the overall cycle time is longer than that of this time, and the overall cycle time changes periodically. From numerical examples, it is shown that the order of arrivals of workers at machine 1 affects the overall cycle time. We give some properties on the periodicity of cycle times and discuss about cycle times.

TL;DR: In this article, an error correction model was used to test the relationship between corporate bank loans and commercial papers comprised of post-dated cheques and bills of exchange, and the results showed that corporate bank loan and cheques are substitutes.
Abstract: In this paper, we attempt to find a “channel” through which Greek economy can exhibit a relative “resistance” in a credit crunch. For this purpose, we specify an error correction model so as to test the relationship between corporate bank loans and commercial papers comprised of post-dated cheques and bills of exchange. The results show that corporate bank loans and cheques - bills of exchange are substitutes. This finding combined with the fact that in Greece, the issuance of these papers is positively connected with the informal economic activity which in turn rises during economic downturns, has a strong economic implication regarding the ability of Greek economy to partly “amortize” the shocks connected with the current financial crisis.
