    by Jimbo Henri Claver 
    Abstract: This study assessed the impact of food advertising on purchasing and consumption behaviour of children in emerging consumption markets. A case study of consumption market in Kabul, Afghanistan was conducted on various dimensions by measuring the impact of several factors. The study relied on primary data collected by administering 385 survey questionnaires to children aged between 5 and 15 years old. Data were analysed with STATA 2013 using regression analysis, correlation analysis and descriptive statistics methods. The data and statistical methods and models were tested for validity and reliability; these tests includes Cronbachs alpha, Jarque-Bera, Bruesch-Pagan/Cook-Wisberg, Winsorization, Skewness and Kurtosis, Akaike Information Criteria (AIC), and Variance Inflation Factor (VIF). The study found that television advertising had the most influence on purchasing and consumption behaviour of children directly or indirectly through their parents. The study also found that the nature and magnitude of advertising outcome on childrens purchasing and consumption behaviour varies based on factors such as age and gender of children. The study provided first-hand information for food industry owners, parents, advertisers, and governmental policy makers.

  • A Queuing-based Mathematical Model for the Congested Network Design Problem under Demand Uncertainty   Order a copy of this article
    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.

  • The TODIM multi-criteria method applied to the ANBIMA ranking of Brazilian investment funds   Order a copy of this article
    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.

  • Building loyalty in e-commerce: Does consumer income matter?   Order a copy of this article
    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.

  • Research on Drug-Induced Liver Injury in Association with Co-Infections and Anti-Tuberculosis Drugs   Order a copy of this article
    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   Order a copy of this article
    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.

  • The effects of performance systems and management concepts on organizational performance in the public sector in Denmark   Order a copy of this article
    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.

  • Towards a Formal Specification for an AADL Behavioral Subset using the LNT Language   Order a copy of this article
    by Hana Mkaouar, Bechir Zalila, Jérôme Hugues, Mohamed Jmaiel 
    Abstract: The analysis of real-time systems designed by architectural languages such as AADL (Architecture Analysis and Design Language) is a challenging research topic. In such a context, formal methods become an advocated practice in software engineering for rigorous analysis. Yet, they are applied on specific formalisms to be analyzed on dedicated tools. This paper studies the formal verification of real-time systems modeled with the AADL language and its Behavior annex. We define a formal semantics of an AADL behavioral subset using the LNT language. This work is illustrated with a robot case study.

  • An Integrated GRA-DEMATEL-ANP Framework for Evaluation of Barriers to Implementation of Green Supply Chain Management in Manufacturing Industries   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • An Improved Authenticated Key Agreement Protocol with Privacy Protection for Mobile Healthcare Systems with Wearable Sensors   Order a copy of this article
    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.

  • Firm size effects on stock returns in mergers and acquisitions in Asian emerging markets   Order a copy of this article
    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.

  • LEADERSHIP MODELS IN THE GAMIFICATION CONTEXT - CASE STUDY   Order a copy of this article
    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.

Towards this direction, this paper proposes an effective integrated architectural model and framework for the purpose of formulating, aligning, executing and evaluating in a combined way both Business Strategy and Information Technology Strategy. In order to achieve this goal, key concepts and respective frameworks, such as the strategic alignment, the balanced scorecard, the strategic architecture, and the business architecture are thoroughly investigated. Then, we progressively integrate all of them in one model in order to eliminate the weaknesses of the previous models and provide the enterprises and the organizations with an innovative, useful and applicable tool. The proposed model can lead to high business performance, agility and consistency in decision making, improved resource control, refinement capability via feedback mechanisms, increased coordination, quality of service, and positive financial results.

  • A hybrid systems approach to determine effective factors on the growth of marine industries in developing countries   Order a copy of this article
    by Shahdad Eshaghpour, Seyed Hossein Hosseini, Seyed Amir Aghaei, Mohammad Saeed Seif 
    Abstract: Marine industries have always been provided power and development for countries both militarily and economically. Due to the lack of essential economic, industrial, and technological infrastructure in developing countries, the development of marine industries, has been facing serious obstacles. As a developing country, Iran has been tackling similar barriers. This paper aims at developing a conceptual model, to examine this complex problem, using a systems approach by which subsystems and casual loop diagrams have been created. Afterward, DEMATEL technique has been used, revealing the most effective variables. The research can remarkably help practitioners in appropriate recognition and investigation of marine industry development challenges. The results show that "domestic supply chain development", "special rights and benefits for employees", "increase in manpower efficiency", "domestic demand absorption", "low-interest loans with suitable guaranties", and "effective and integrated management" are the key factors and main issues in marine industry progress in developing countries.

  • Musculoskeletal health problems and relationship of risk factors among manual Clay Brick Sector Workers   Order a copy of this article
    by Manoj Kumar Sain, M.L. Meena, G.S. Dangayach 
    Abstract: Adverse working conditions with prolonged awkward postures and traditionally designed hand tools result in musculoskeletal health problems among brick kiln workers. The occurrence of musculoskeletal problems depends on various physiological and work-related factors. The present cross-sectional study aims to determine the prevalent musculoskeletal health issues among 150 manual clay brick sector workers and the relationship of risk factors with these issues. Random sampling survey using modified Nordic questionnaire and postural assessment methods, Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) were used for data collection. The association between prevalence of MSDs and risk factors was determined by binary logistic regression. Most prevalent musculoskeletal issues were found in shoulder (56.15 %), wrist (50.77%) and lower back (50%) regions. Musculoskeletal issues were found to be associated with personal and work-related factors. The average REBA and RULA scores for all tasks indicated high postural risk. The outcomes of the study pointed out the need for ergonomic interventions to reduce the issues among kiln workers.

  • Examine Factors Affecting Success of Enterprise Resource Planning System Adoption on Organization Performance among Medium-Sized Enterprises Sector   Order a copy of this article
    by Adejare Yusuff Aremu 
    Abstract: This study presents a conceptual framework to determine the factors affecting the failure and success of ERP system adoption in medium-sized enterprises. These factors are technological change, government policy and the performance of medium enterprises. The current study also applied resource-based value, contingency and diffusion of innovation theories to explain the factors affecting ERP system adoption. In this light, a proposed conceptual framework has been designed based on information obtained from a newly developed questionnaire which were distributed to one hundred and forty-four (144) medium-sized enterprise organizations in Ondo State, Nigeria. For this study, the CEO / director and managers of these companies were selected as the key respondents and the empirical data were analyzed using the Partial Least Squares Structural Equation Modelling. The result obtained revealed that technological change significantly influences the adoption of the ERP system to enhance the performance of medium-sized enterprises organizations. However, government policy has no significant relationship with the performance of medium-sized enterprise firms. In this light, the outcomes of this study are useful for organizations adapting ERP to help them strategize future ERP system implementation in different industry, such as education, SMEs and multinational companies. However, this study is limited to medium-sized enterprise firms as the author has not included other measures of medium-sized enterprises performance factors.

  • Factors of technology transfer and its relation to success   Order a copy of this article
    by XIMENA Lopez-Mendoza, David Mauricio 
    Abstract: Technology transfer is the process by which science and technology developed in universities are transferred to companies for technical, scientific, and economic development. Success in this process is effected by several factors; hence its importance to identify them and note how they influence the different dimensions of the success of the technology transfer process. The critical success factors are analysed: adaptation to change, government policies, selection criterion of the project portfolio, work environment, product satisfaction, entropy, stress, and ethics; and, how these effect successes in its three dimensions scientific, social, and financial. A study was carried out based on confirmatory factor analysis and structural equations model on 84 universities in four countries of the Andean region dat confirm to 85% confidence dat the proposed factors influence all the success dimensions of the technology transfer process.

  • Performance Analysis of Retinal Features for Diabetic Retinopathy Characterization and Diagnosis   Order a copy of this article
    by Charu Bhardwaj, Shruti Jain, MEENAKSHI SOOD 
    Abstract: Automated retinal feature extraction serves as a significant step for accurate Diabetic Retinopathy (DR) diagnosis and screening. Ophthalmologists highly rely on retinal fundus segmentations for the treatment of severe eye related abnormalities; glaucoma, strokes, occlusions and diabetic retinopathy. DR caused due to prolonged retinal blood vessel deterioration and if it is left untreated, it may lead to severe vision complications. This work proposes a mathematical morphology based optical disc localization and blood vessel extraction approach to determine vascular alterations and expedite accurate identification of pathological symptoms. Shape and pixel based features are evaluated for optical disc localization and blood vessels obtained along with a new set of fractal features to determine the self similarity between the extracted blood vessels and ground truth vessels labelled by the professional experts. A three-fold analysis is done on two benchmark databases; DRIVE and STARE, consisting of visual, statistical and performance analysis of the proposed blood vessel extraction approach. Performance evaluation of the proposed approach yields average accuracies of 95.50% and 94.80% respectively, when tested on benchmark DRIVE and STARE databases. The accuracy values obtained are appreciable and comparable to the various researches done in this field.
