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.
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.
Keywords: Leadership; Models; Gamification; Management Game; Organizational Learning.

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.
Keywords: Retinal Features; Blood Vessel; Diabetic Retinopathy; Fractal Features; Optical Disc Localization; Mathematical Morphology.
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.

The Dead Goat Syndrome in Organisations
by Robert M. Yawson, Emmanuel Osafo
Abstract: The use of metaphors to explore the connection between theory and practice in organisation and leadership studies has proven to be highly effective. This paper discusses the dead goat syndrome (DGS) as a benchmark in discussing the importance of metaphor in organisation life and to identify the various leadership types that conform to the DGS metaphor. The dead goat syndrome emanates from a popular Ghanaian metaphor literary meaning a goat that is already dead does not fear to be thrust with a knife. Using this metaphor, we present a new lens for looking at leadership effectiveness and identify the basis for certain leadership behaviours in organisations. We illuminate some definitions of metaphor by briefly reviewing the literature on the classical views on metaphors, metaphors in organisational theory development, and how the DGS metaphor can be utilised to identify certain leadership behaviours in organisations.

Workforce Gender Diversity and Corporate Performance
by Khaoula Aliani, Imen MHAMID, Ghousia Khatoon Khatoon
Abstract: Gender diversity is equitable or fair representation of people of different genders. Gender diversity, as it relates to a work environment system, means that men and women are hired at the same rate, paid equally for equal work, and promoted at the same rate. The study conducted by McKinsey & Company titled 'Woman Matter' suggests that the companies where woman are most strongly represented at the level of top management may perform better. The objective of this paper is two-fold. First, we aim at understanding the impact of the feminisation of the lowest ranks of the company on the performance. Secondly, we focus on analysing the relationship between the disclosure of the feminine values at the lowest ranks and the performance. Based on a sample composed of 209 unlisted Tunisian companies, the empirical analysis indicates that the existence of the female values at the lowest echelons influences positively and significantly the operating profit of the Tunisian companies.
Keywords: Diversity; Gender; Workforce; Corporate Performance; Generalized method of moments.

by Yasmeen Shamsi Rizvi
Abstract: Purpose: The purpose of this review article is to analyse the role of green human resource management (GHRM) in the implementation of the environmental sustainability (ES) strategies of organizations and how it is related to environmental sustainability performance (ESP). This study also analyses the role of the other internal fields of green intellectual capital (IC), specifically, green human capital (GHC), green organizational culture (OCul.) and environmental management (EM) systems in context of green human resource management (GHRM) and ESP.
Design/Methodology/Approach: To achieve its objectives, the paper is divided in four parts: 1. Introduction 2. Literature review 3. Model 4. Discussion and Conclusion. Literature on ESP, GHRM and other components of green internal IC, namely, environmental management (EM), GHC, and green oOCul. has been reviewed. Seven functions of GHRM have been studied. A macro-level analyses of ES issues in India was discussed. Information on the role of job description was supplemented with that from interviews.
Findings: The study found that an integrative approach is required for the achievement of green goals. Based on literature analysis, ESP is found to be related to GHRM and other internal fields of green IC. GHRM also has interlinkages with other internal fields of green IC. A knowledge body has been created for further studies and research gaps have identified. These issues have been found to be at a nascent stage in a developing country--India.
Implications: This study will help practitioners understand the relationships between the variables which would enhance their abilities in implementing ES strategies. It also makes a case for systems approach to green management and also for the robust formulation and implementation of environmental strategies in organizations where these may be at nascent stages. A need for focus on building green intellectual capital for the achievement of green goals has also been highlighted through this study. A research model based on the hypothesized relationships has been developed for further testing and areas of research have been identified for further studies.

Event detection in educational records: An application of big data approaches
by Alan D. Smith
Abstract: As the exponential growth of predictive analytics applied to educational institutions continues, with various goals in mind, an event detection system could serve as the foundation for more sophisticated predictive systems What is envisioned is a system that flags educational records that have a sudden change (i e event detection in education records) The basic algorithm prosed would retrieve the current weeks data for each student, calculate Euclidian and Mahalanobis Distances among current weeks data, and historical student data, sort all student data based on these distances, and update historical data with current data The educational event detection system uses a query-based, R-tree structure, big data analytical approach A simulated experiment determined that the event detection algorithm was able to detect relatively small changes in simulated data Although, the units of the 2 distance metrics do not coincide, so distance measurements are not directly comparable, the event detection algorithm with the two different distance metrics have comparable CPU run times. Research and suggestions for constructing predictive analytics on student learners' attrition/retention approaches were documented.

A size and impact analysis of digital footprints
by Chia-Chi Teng, Whitney Maxwell
Abstract: Personal information accessible online can be known as a digital footprint. While most of us have a digital footprint in todays technological society, few if any, know what it encapsulates or how to manage it. Technology and personal information are becoming more intertwined as we become more dependent on technology with everyday activities. In addition to basic information such as names, addresses, and phone numbers; personal information also includes ones demographic, interests and shopping history which is used by businesses to track consumers spending and even predict future purchases. With such wide variety of personal information being captured and exposed online, not all are equally valuable or personally unique. This study proposes methods to identify the content, size and impact of an individuals digital footprint by measuring the discoverability of various types of personal information.

Customer Experience with Self-Service Technologies in Banking Sector: Evidence from Nigeria
by Chidera. C. Ugwuanyi, Joseph. I. Uduji, Chukwunonso Oraedu
Abstract: This study investigates experiential indicators within the retail banking sector. Specifically, the paper examines the drivers and outcome of self-service technologies experience and customers satisfaction. A survey research design was used to generate data from a densely populated Nigerian university and was analysed using the Structural Equation Modelling Partial Least Square Technique (SEM-PLS). Findings show that perceived ease of use and perceived usefulness of banks self-service technologies are strong indicators of customers cognitive experience, and in turn influences customers satisfaction. Perceived ease of use was also found to directly predict perceived usefulness and customer satisfaction. An interesting, but surprising result was that perceived usefulness did not directly predict customer satisfaction, meaning that customers expect the performance of banks self-service technologies to be a basic requirement. This perceived usefulness is therefore not necessarily a factor influencing customers satisfaction. These findings and important implications for bank managers were discussed herein.
Keywords: Customer experience; Perceived ease of use; Perceived usefulness; Self-service technology; Nigerian banking sector; PLS-SEM; Systems/Technology.

Formal design model for service-oriented system: a conceptual perspective
by Amit Kr Mandal, Anirban Sarkar
Abstract: The numerous design specifications in the service-oriented architecture (SOA) standard space reflects knowledge captured from the various perspectives. However, most of these approaches merely exhibit any compliance with service design facets described in reference architectures. Moreover, majority of this approach lacks correspondence between the business process facets to service design facets and its real-world effects. This leads to semantic gap between services representation, its association with the business processes, and invocation of services to its real-world effects. In this paper a formal model of service-oriented system (SOS) is proposed. The SOS is divided into information model, process model and action model. The semantic relationship between these 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 flexible, reusable and scalable service composition and it follows the open reference standards of SOA.
Keywords: service-oriented system; SOS; service model; business process; service binding; service composition.
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 analyses, through a multicriteria approach producing if-then rules, the possibility of forecasting the default probability (PD) 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. The 'RoughSets®' package, in 'R', was used as support for the analysis and forecasting system.
Keywords: default probability; multicriteria analysis; rough sets theory; RST; credit risk assessment; forecasting system.

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, M.L. Meena, Himanshu Chaudhary, Govind Sharan Dangayach
Abstract: 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. The output voltages from the sensors were converted into angles by implementing LabVIEW-Interface-for-Arduino based graphical environment. Ten experienced weavers participated in the study. Dynamic recordings of the finger, wrist and elbow bending trajectories were measured using sensory electro-goniometer. Assessment of repetitive task technique was used to identify the postural risks. Based on 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. The cost-benefit breakdown revealed that wearable electro-goniometer is cost-effective as compared to commercially available electro-goniometers. 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.

Study of enhancing employee engagement at workplace by adopting internet of things
by Sumi Jha, Preeti Khanna
Abstract: The internet of things (IoT) continues to affirm its importance in the context of information and communication technologies (ICT) for the development of organisation and society. The ecosystem of IoT may still be in a nascent state but is rapidly evolving. As far as the business demand is concerned the demand for IoT solutions seems to be coming from all industry verticals across all functions. Therefore, it is required to align different business functions to IoT. Human resource management function is one such pivotal function. It is believed that good HR practice enhances employee engagement. There is an increasing awareness that employee engagement is pivotal to successful commercial and business performance, where engaged employees are the "backbone of good working environments where people are industrious, ethical and accountable" (Levinson, 2007; Cleland et al., 2008). The paper presents an analysis of human resource management practices and IoT interventions on employee engagement at workplace. Further, the paper discusses that, in practice, organisations need to continuously realign work practices with IoT to enhance the employee engagements, and stakeholder interests.
Keywords: internet of things; IoT; employee engagement; systems; human resource management; technology.
The unique effect of dynamic motivation and different perception of organisational politics on students' ethics
by Setyabudi Indartono
Abstract: Although scholars coincide with the need to support higher education students toward higher levels of ethics, their findings lack dynamic individual behaviour and environmental influence. Students' motive and their perception of external dynamics are closely to react to their ethical behaviour. Various education systems and technologies are believed to boost students' ethics behaviours differently. This study investigates the effect of motivation and perception of organisational politics on students' ethics. It is employed by 2,375 higher educations' students. This study expected that students' motivation and their perception of organisational politics have a significant unique effect on their ethics. Multiple regressions are used to analyse the data. The better ethical behaviour of the student is shown by a student with higher motivation and perceives less political behaviour at school. The unique findings show that motivation able to strengthens the effect of perception of organisational politics on their ethical behaviour, and perception of organisational politics strengthen the effect of students' motivation on their ethical behaviour. Implications and future research are discussed.
Keywords: motivation; perception of organisational politics; POP; students' ethics; systems; technology.
