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.

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
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.

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.

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.
Keywords: firm size effect; mergers and acquisitions; Asian emerging markets; market model; alpha coefficient; beta coefficient.

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.

by Adejare Yusuff Aremu, Arfan Shahzad, Shahizan Hassan
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.

Performance Analysis of Retinal Features for Diabetic Retinopathy Characterization and Diagnosis
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.

The Effect of the Consumers Engagement in the Process of Adopting Functional Applications: the Mobile Banking Case
by Cid Goncalves Filho, Plínio Rafael Reis Monteiro, Melissa Morais Simplício, Renata De Sousa Da Silva Tolentino
Abstract: The use of mobile applications in the banking sector has achieved a representative growth with customers that use uniquely online devices to transact. In this scenario, this paper has the objective of analyzing the impacts of the adoption of functional applications in the improvement of consumer-brand relationships. A survey, which involved 408 respondents, was conducted. The basic model for this study was the Unified Theory of Acceptance and Use of Technology (UTAUT), whose effects were analyzed by the moderation perspective exerted by the consumers engagement with the brand. According to the results, it was observed that effective engagement alters the modus operandi of adopting a functional technology, starting from the constructs of performance, the expectation of effort, social influence and facilitating conditions. The field data demonstrated differences between the UTAUT models tested in groups of high and low engagement. This research presents a new approach for the adoption of technologies to bring the role of engagement as a factor of influence.
