Decreasing operational costs of nonprofit community-based blood centers
by Sima M. Fortsch, Qunfeng Liao
Abstract: Blood is a necessary resource for hospitals; however, acquiring blood poses several challenges for blood centers and hospital blood banks. First, blood is a perishable and natural resource that cannot be manufactured at the time of need. Second, supply and demand of blood are uncertain due to seasonality, natural disasters, and availability of donors. Third, blood centers and hospital blood are challenged in acquiring blood economically, as the price of one package of blood has reached the price of an iPad. Prior research shows the popular Economic Order Quantity (EOQ) model is not applicable to blood orders due to the ample shortages that result from the model. In order to provide fresh inventory and to reduce operational costs, this study employs an econometric methodology known as AIAO (ARMA-in-ARMA-out, where ARMA stands for Autoregressive Integrated Moving Average) combined with lean managerial accounting practices to place orders. Results show that applying the above system of ordering could supply fresh blood inventory and decrease operational costs for blood centers.

Career choice in teaching among engineering graduates: A study of the Altruistic, Extrinsic and Intrinsic factors
by Sweta Bhattacharya, V. Raju
Abstract: The Indian higher education system is the third largest in the world producing immensely talented manpower, winning accolades all across the world. But the system faces faculty crunch majorly in the engineering education sector failing to attract this huge talent pool towards teaching professions. The study analyses the effect of Altruistic, Extrinsic and Intrinsic factors pertaining to the choice of teaching career using survey research based statistical analysis and Analytical Hierarchy Process. The results of AHP reveal Intrinsic factor as the highest ranked factor affecting teaching career decisions which is supported by the consistency ratio value (0.033<=0.10). The effect of age, gender and program of study is also studied which reveal that age and program of study has significant effect on the intrinsic factor. The paper finally recommends policy amendments relating to the intrinsic factor so that more students could be attracted towards teaching profession.

SCORE Framework: A Layered Approach for Enterprise Architecture
by Priyanka Chakraborty, Anirban Sarkar
Abstract: Continuous and rapid changing business environment is a driving force for agile enterprise system because several new services and solutions are emerging from the multiple exchanges over time. A suitable Enterprise Architecture Framework (EAF) must be established for established for effective delivery of enterprise level technologies by adopting service-oriented architecture (SOA). However, existing non-SOA based EAFs are lacking of adopting such agility. On the other hand, existing SOA-based EAFs though can resolve the issues of flexibility and scalability, but they are less efficient to handle context sensitivity and agility of Enterprise System. To address these challenges, this paper proposes a novel SOA-based EAF, called SCORE framework that is comprised of five loosely coupled layers. Besides formal description, the proposed SCORE framework is illustrated with detailed case study on Care Management System. Moreover, a detailed comparative analysis is performed to express the strength of the proposed framework over the existing approaches.

by Amir Abbas Shojaie, Mohamad Amin Kaviani
Abstract: In this study, we propose a queuing-based mathematical model for analyzing the congestion phenomenon in a transportation network. For this purpose, we present a mathematical model for network design with the objective of the cost minimization and optimal demand satisfaction under demand uncertainty situation. The queuing theory usage helps to better model the congestion item caused by customers referrals to the facilities of the transportation network. Moreover, a numerical example is solved to demonstrate the validity of the proposed model. To the best of the authors knowledge, this is the first study which looks at the congested transportation network problem considering demand uncertainty from a queuing theory perspective.

Structural Investigation of service supply chain: A social network analysis approach
by Sumit Sakhuja, Vipul Jain
Abstract: In this study the structure of a service supply chain is analyzed using social network analysis approach. Service supply chains consist of peoples and organizations connected in form of a network. The network is formed by the combination of ties between different players in the chain/network. These players are dependent upon each other and there exists flow of material or flow of information between players. Despite the longevity of the social networks perspective, the product supply chains as well as the supply chain in services are less explored from the social network perspective. A case study on supply chain of property purchase has been discussed in this paper that is analyzed with the help of social network analysis approach.

The TODIM multi-criteria method applied to the ANBIMA ranking of Brazilian investment funds
by Frederico Silva Valentim Sallum, Luiz Flavio Autran Monteiro Gomes, Maria Augusta Soares Machado
Abstract: ANBIMA, the Brazilian Financial and Capital Markets Association, monthly presents the ranking of investment funds management by category. This ranking makes available information about the management of resources from players that invested in funds in Brazil. The institutions that are included in this ranking are ordered based on the total amount of the net equity under management in all categories of investment funds. The research presented in this article applies the TODIM multi-criteria method for building the ANBIMA ranking of June/2017 using the 10 best-positioned institutions. In order to accomplish this, each participating institution is considered as an alternative and each category of investment fund functions as a criterion. This allows for a comparison between the ANBIMA ranking against the ranking obtained by using the TODIM method. This comparison points to the possibility of making use of a new, enriched way to order the institutions based on pairwise analyses and taking into account expressions of gains and losses.
Keywords: ANBIMA Ranking; Management of Investment Funds; Ranking of Investment Funds; TODIM Method.
Building loyalty in e-commerce: Does consumer income matter?
by Viviane Ferreira, Juracy Parente, Mateus Ponchio, Felipe Zambaldi
Abstract: In emerging markets, the rapid expansion of online retailing is mainly driven by new adopters from lower-income consumer segments. However, little is known about the behaviour of this group in online retail. This study evaluates the relationships between e-loyalty, e-satisfaction, e-trust and e-quality, paying particular attention to the moderating role of consumer income. Data were collected from a sample of 1,020 Brazilian consumers via a web survey and were analysed using structural equation modelling (SEM). Among the main results, this study finds that consumers from the higher-income group pay more attention to the quality of website information, while consumers from the lower-income group emphasize the importance of fulfilment. E-satisfaction is more important than e-trust in determining e-loyalty and these relationships are moderated by income. Online retailers should pay special attention to tailoring their promotional efforts to foster consumer loyalty according to different consumer income groups.
Keywords: loyalty; e-commerce; emerging markets; quality; satisfaction; trust; structural equation modelling; income moderation effect; Brazilian consumers; technology.

by Ximena Lopez-Mendoza, David Mauricio
Abstract: Technology transfer is a tool for the development of societies and its success is affected by several factors; hence, it is important to identify them and note how they influence the different stages of the technology transfer process. The present work identifies new factors (adaptation to change, government policies, selection criterion of the project portfolio, work environment, product satisfaction, entropy, stress, and ethics), the same ones that have been supported in the theories of human and organisational behavior, these affect all stages of the technology transfer process from university to industry. The study was made based on confirmatory factor analysis and the model of structural equations and was carried out on 85 universities in four countries of the Andean region. The obtained results confirm that, at 95% confidence, the proposed factors influence all stages of the technology transfer process.
Keywords: Factors of technology transfer; technology transfer; stages of technology transfer; model of structural equations.
Research on Drug-Induced Liver Injury in Association with Co-Infections and Anti-Tuberculosis Drugs
by Wu Li-Ya, Weng Sung-Shun, Wong Wing-Wai
Abstract: This study uses data mining techniques to find out the risk factors for the tuberculosis (TB) patients with drug-induced liver injury (DILI). The Taiwan National Health Insurance Database is used for collection of domestic TB cases during 2004-2011 to study these TB patients and their drug prescribing patterns in order to build a model to predict the risk of drug-drug interaction between Hepatitis (HBV/HCV), Acquired Immune Deficiency Syndrome (AIDS) and TB. The results out of the total 188,032 TB patients have shown that 77,574 have taken anti-TB drugs. Afterwards, DILI occurred in 0.7% of the cases. Besides, for those DILI patients associated with TB and HBV or HCV, this study reveals that DILI is associated with the use of ethambutol and rifampin. It is suggested that TB patients associated with HCV should pay attention to their uses of rifampicin, and TB patients (especially males) associated with HBV should pay attention to the ethambutols impact on DILI. Moreover, our results also showed that having both AIDS and TB shows no significant effect on DILI.

Extension and Adaptation of an Aspect Oriented Programming Language for Real-Time Systems
by Wafa Gabsi
Abstract: Aspect-Oriented Programming (AOP) supports the separation of concerns cutting across the implementation of a software application to avoid scattering and tangling. We focus on the integration of this paradigm in the development of real-time systems. AOP is based on the weaving process to automatically integrate separately created segments of code, into the application. In the context of real-time systems, this can compromise determinism by including constructs that may violate real-time constraints beyond the control of the developer. In this paper, we both study and test the AspectAda language, an existing aspect extension for Ada, in order to adapt its implementation to respect real-time constraints. We study this language's grammar, runtime and especially weaving operations. Then, we extract its limits and provide solutions to adapt it to support real-time constraints. Finally, we propose a new architecture of the compiler/weaver to overcome the problems of the existing one and we detail its different parts.
Keywords: AOP; AspectAda; Ada; Real-Time Constraints; Compiler; Architecture.
The effects of performance systems and management concepts on organizational performance in the public sector in Denmark
by Steen Nielsen, Christian Nielsen
Abstract: This paper explores how different types and groups of performance systems and management concepts explain the cross-sectional variations of organizational performance within the public sector, by applying a Structural Equation Modelling approach to survey data from 318 respondents in the Danish municipal sector. We argue that links exist between different types of performance systems and a number of performance outcomes. More specific, we explore how different performance measures such as benchmarking, employee significance, innovation, accounting models and systems, strategy execution and cost allocation directly or indirectly affect performance. In particular, our data suggests that the association between adoption of accounting systems and performance is fully mediated through both strategy execution and cost allocation. Practitioners can improve empirical specifications for examining the effects of different measures and gain an understanding of the mediating effects of accounting and management concepts. These findings add to our understanding of the functioning of performance management systems within the public sector in theory and in practice.

An Integrated GRA-DEMATEL-ANP Framework for Evaluation of Barriers to Implementation of Green Supply Chain Management in Manufacturing Industries
by Mohamad Sadegh Sangari, Fatemeh Nikkhoo, Maziar Khoshsirat
Abstract: Nowadays, green systems and technology have received much attention due to the increased concerns about environmental issues. However, companies have faced various barriers in its implementation. Thus, proper identification and evaluation of these barriers is necessary to achieve effective results. In this paper, an integrated framework based on Grey Relational Analysis (GRA), DEMATEL, and Analytic Network Process (ANP) methods is proposed to identify and evaluate the barriers to Green Supply Chain Management (GSCM) implementation in manufacturing industries. Drawing upon an extensive literature review, a reference framework of the GSCM barriers is developed consisting of two main groups, namely internal and external barriers. GRA is used to deal with ambiguity in experts assessments. Also, the interactions and cause-effect relationships among the GSCM barriers are evaluated using DEMATEL. The relative importance of the barriers is then identified by integrating results of DEMATEL and ANP. The proposed framework is implemented in a case study of an auto manufacturing company. The results show that, by taking interrelationships of the barriers into consideration, the factors related to customer and market and business partners as well as social and managerial factors are the most important barriers to effective implementation of GSCM initiatives in the case company.

Formal Design Model for Service Oriented System: A Conceptual Perspective
by Amit Mandal, Anirban Sarkar
Abstract: The numerous design specifications in the service oriented architecture (SOA) standards space reflect knowledge captured mainly from the different perspectives. However, most of these approaches merely exhibits any compliance with the service design facets described commonly in different reference architectures. Moreover, most of these literatures merely drawn any correspondence between the business process facets to service design and further service design facets to real-world effect. This leads to semantic gap between services representation, its association with the business processes, and invocation of services to its real-world effects. To overcome these issues in this paper a formal model of service oriented system (SOS) has been proposed. To represent the concepts properly, here the SOS is divided into Information Model, Process Model and Action Model. The semantic relationship between the models helps in reducing the gap between the business processes and services, as well as services to its real-world effect. Further, the proposed service model facilitates the flexible, reusable and scalable service composition and it is in compliance with the open reference standards of SOA.

A multicriteria forecast of the default probability in credit risk assessment
by Ayrton Benedito Gaia Do Couto, Luiz Flavio Autran Monteiro Gomes
Abstract: This study analyzes, through a multicriteria approach producing if-then rules, the possibility of forecasting the default probability for low-default portfolios in credit risk assessment. This approach relies on the simultaneous and complementary application of fuzzy and rough sets theories. The calculation of this probability is normally subject to judgments of experts, which imply subjectivity, imprecision and uncertainty of the results. In the proposed approach, the inferred if-then rules for a decision table generated by a simulation of 50 companies allowed the production of a knowledge base for the forecasting of classes of default probabilities.

Development and evaluation of wearable electro-goniometer for the assessment of repetitive efforts and measurement of joint trajectories during carpet weaving
by Ashish Kumar Singh, Makkhan Lal Meena, Himanshu Chaudhary, Govind Sharan Dangayach
Abstract: This study is first of its kind to investigate the occupational goniometry while using weaving hand tools. The aim is to construct, calibrate and validate a low-cost sensor-embedded glove and elbow brace. This article establishes a common thread between electro-goniometry and postural assessment techniques. A low-cost sensory electro-goniometer embedded with resistive bend sensors was evaluated for the measurement of accuracy and output linearity. The output voltages from the sensors were converted into angles by implementing LabVIEW Interface for Arduino (LIFA) based graphical environment. Ten experienced female weavers participated in the study. Dynamic recordings of the finger, wrist and elbow bending trajectories were measured using the sensory electro-goniometer. Data from the electro-goniometer, photographs, and videotapes were used to investigate the postures involved while weaving. Assessment of repetitive task (ART) technique was used to identify the postural risks. Based on the data output from each sensor, the voltage to angle optimal linear models were obtained for the measurement range of 0˚-90˚ with 5˚ steps. The accuracy of the sensors was found within the limits of traditional goniometry. ART priority scores (ES>22) for subtask 1 and 2 revealed that working posture during carpet weaving requires necessary action and hand tools should be redesigned. The low-cost electro-goniometric glove and elbow brace for measurements of hand movements could be a promising tool for postural assessment and safety systems.

Firm size effects on stock returns in mergers and acquisitions in Asian emerging markets
by Jianyu Ma, Yun Chu, Robert Beaves
Abstract: This study finds that firm size effects can be captured at every step during the process of estimating abnormal returns. Our small firm portfolio has higher averages with respect to alpha, total risk, firm-specific risk, expected return, actual return, and abnormal return. However, this small firm portfolio has a smaller beta average, which contradicts most prior findings which suggest that small firms tend to have higher betas. The observed higher alpha coefficient (not beta coefficient) makes a major contribution to the observed higher expected return for small acquiring firms. Small acquiring firms still gain higher abnormal returns than large acquiring firms even when the higher expected returns of the small firms are incorporated in the process of the abnormal return estimation.

Financial Integration of Asian Markets: Multivariate Cointegration, Causality and Variance Decomposition
by Lamia Kalai
Abstract: The aim of this paper is to study financial integration of East Asian equity markets. To this end, we examine time series of 11 stock market indices. We conduct a multivariate cointegration analysis using the Engle-Granger test to determine the presence of a long-term equilibrium relationship between the studied indices. The Granger procedure defines the meaning of causality. Vector autoregression helps to model the dynamic relationships between the different markets. Forecast error variance decomposition captures much of the information on the dynamics of the indices VAR system and allows for checking the relative contribution of each shock in explaining price movements. The results indicate that there are long-term stationary equilibrium relationships and causal links between these markets. The results on the forecast error variance decomposition show that the price indices of emerging Asian countries can explain their caused variance and confirm that financial integration prevails in the region.

LEADERSHIP MODELS IN THE GAMIFICATION CONTEXT - CASE STUDY
by Joao Pereira, Renato Lopes Da Costa, Jose Borges, Maria Miguel
Abstract: The present work addresses the association of leadership quality factors (e.g. decision direction success and effectiveness of strategic moves) and gamification. In the last 30 years, commerce and international investments have increased faster than world economy as a whole. In order to deal with such complex environment, leaders and their decision making processes (either formal or informal) play a crucial role. Therefore, the study of leaders performance while attempting to solve real-life gamified scenarios, correlated with leadership factors, provide a powerful (yet underutilized) analysis instrument. The work proposed in this paper attempts to contribute for the business management area, which is typically focused in determining correlations between leadership factors framed by literature models and behaviour analysis of leaders in the different contexts.
The present investigation comprehends the following objectives: analysis of leadership models and their framework in the scope of a management simulator; the effectiveness of gamification for organizational learning. Such objectives are achieved through: correlating operational results with leadership styles for players managing a company; to understand how the management style can and will affect the game final results; to identify prominent leadership styles during the game. The assessed sample of gamers consisted of 92 players. At the end of the game each player answered a leadership survey to assess leadership factors. The results obtained suggest a stronger focus on a decision making scope of traits model.
Keywords: Leadership; Models; Gamification; Management Game; Organizational Learning.
Assessing service quality using fuzzy numbers and TOPSIS: an application to self-contained and serviced apartments
by Juan Carlos Martín, Cira Mendoza, Concepción Román
Abstract: This research paper proposes a methodological framework to assess the service quality (SQ) of self-contained and serviced apartments (SCSAs). The study is based on 2,753 surveys administered in a SCSA resort located in the south of Gran Canaria Island. SQ is based on a questionnaire that contains a list of 48 attributes. The answers' format is based on a four-facial expressions scale that cannot be easily transformed in a numeric scale. Thus, the ambiguity and possible biased analysis has partly overcome applying the fundaments of the fuzzy set theory. TOPSIS approach is then employed to obtain a synthetic SQ indicator. Finally, an observation-attribute relative performance analysis is developed to identify the operational areas that need improvement or can keep up the good work. The findings of this study may assist managers and policy planners with important insights about the attributes that tourists value more.

Managing university rank and tenure decisions using a multi-criteria decision-making approach
by Enrique Mu, Cynthia Busin Nicola
Abstract: Faculty evaluation in academia is a serious concern for higher-education administrators. This study develops a model for rank and tenure (R&T) decisions using an analytic hierarchy process (AHP) multi-criteria decision-making (MCDM) approach. Literature review suggests most R&T evaluations are rather subjective in many institutions. A case method approach is used for the development of a model and demonstration of its use. The proposed evaluation model provides objectivity, transparency and customisation for R&T committee decisions in higher-education institutions.
Keywords: analytic hierarchy process; AHP; rank and tenure; R&T; university promotion decisions; decision transparency.
Hedonic preference for technological devices justified by utilitarian application
by Emílio José Montero Arruda-Filho
Abstract: This study analyses consumer behaviour for bundled mobile phones, and tests the perception that integrated products have higher hedonic, rather than utilitarian, value. The study covers a variety of scenarios based on brand, price, and preference (hedonic or utilitarian) in the selection of mobile telecommunications devices. Two studies are developed on two specific themes: benchmarking of hedonic and utilitarian values according to consumers' current mobile phones, and hypotheses testing of consumer preferences related to hedonism/utilitarianism under the conditions of brand, price, and mobile characteristics (kind of convergence) proposed. This study enhances understanding of consumers' preferences and market tendencies according to their values related to hedonic and utilitarian characteristics converged in mobile devices. Thus, it has academic implications related to the theory of technology convergence according to the characteristics of new products that can lead to a combined hedonic, social, and utilitarian values perception. In terms of practical implications, the findings enhance comprehension for enterprises regarding which features/attributes, according to significance, are most closely related to the various scenarios that consumer are exposed to.
Keywords: hedonic value; utilitarian value; technology preference; bundle products.
The impact of governmental policy on the relationship between IT systems inputs and business performance: a comparison of large corporations and SMEs in Taiwan
by Hsin-Pin Fu, Hsiaoping Yeh, Wen-Chin Yeh, Tzu-Ling Chien
Abstract: To rapidly adapt to global competition, manufacturers' business models have shifted from a company focus to a focus on the whole supply chain. The 'industry global e-logistics diffusion plan' has provided funds for manufacturers to establish their IT-based logistics systems. However, the performance of such establishments has not yet been evaluated, particularly under the influences of governmental policy. This study investigated the impacts of successful IT-based logistics systems and partnership in the supply chain on business performance moderated by governmental policy and organisational effects. The findings show that, for both large corporations and small-and-medium companies, their IT systems inputs and partnership would positive affect business performance. Governmental policy shows its moderating effect on IT systems inputs boosting up business performance. Yet, particularly for large corporations, organisational factors can also moderate the causal relationship between IT systems inputs and business performance.
Keywords: IT systems input; partnership; organisation; governmental policy; business performance; Taiwan.
Environmental uncertainty and corporate social responsibility
by Brian Chabowski, Sharon Xuerong Huang, Li Sun
Abstract: This study examines the impact of environmental uncertainty on corporate social responsibility (CSR). Using a 23-year panel sample with 3,053 unique US firms and 23,742 firm-year observations, we test the ethics view and risk management view of corporate social responsibility. We find a significant and negative relationship between environmental uncertainty and corporate social responsibility, suggesting that firms are less likely to engage in corporate social responsibility activities when faced with an uncertain environment. Our results support the ethics view of corporate social responsibility. These insights should interest policymakers who implement guidelines on CSR and firms that are considering adjusting their CSR levels. Our results should also provide practitioners with useful insights regarding which specific determinants are associated with a company's level of CSR activities, and interest firms that attempt to incorporate CSR in their business systems.
Keywords: environmental uncertainty; corporate social responsibility; business systems.

An Improved Authenticated Key Agreement Protocol with Privacy Protection for Mobile Healthcare Systems with Wearable Sensors
by Tian-Fu Lee, Yin-Yu Diao, Meriske Chen
Abstract: Authenticated key agreement schemes for mobile healthcare systems with wearable sensors enables patients wearable devices, the mobile terminal, healthcare staff and the healthcare service to authenticate each other and establish a secure communication channel. Recently, Li et al. proposed an authenticated key agreement scheme based on elliptic curve cryptography for mobile healthcare systems with wearable sensors. Although the scheme of Li et al. provides a complete solution for providing healthcare staff, wearable sensors, mobile users, controller nodes and the healthcare service provider with authentication and key agreement, their scheme still fails to realize mutual authentication, user privacy protection, perfect forward secrecy. This investigation discusses these limitations and presents an improved protocol based on the scheme of Li et al. The improved protocol not only avoids the limitations in previous approaches, but also increases the efficiency in computation.
Keywords: Authentication; key agreement; elliptic curve cryptography; privacy protection; mobile healthcare systems; wearable sensors.
