HIGH PERFORMANCE SCHEDULER FOR MULTICAST SWITCHES
by Narayanan Prasanth, Chithra Devi, Raja SP
Abstract: Day-by-day the desideratum for high speed Internet connectivity gets increases and consequently high performance switches are imminent. These switches require efficient schedulers to reach its maximum potential. In this paper, a high performance scheduler is proposed for buffered crossbar switches to work under multicast traffic. The scheduler is able to reduce the starvation effect and thereby achieves maximum throughput with minimum delay than existing algorithms.
Keywords: Crossbar Switch; Scheduler; Starvation; Throughput; Delay.
DYNAMIC SOCIAL ALIGNMENT ON OPERATIONAL LEVEL AND ORGANIZATIONAL PERFORMANCE
by Nikola Levkov
Abstract: Business-IT (BIT) alignment on different organizational levels is thought to facilitate organizational performance. This study investigates how dynamic social alignment on an operational level improves organizational performance. The concept of dynamic social alignment has been introduced based on the theory of dynamic capabilities and the integration of two constructs: IS change agreement and task support satisfaction (TSS). The business value of dynamic social alignment was measured through business process performance and organizational performance. A conceptual model was thus developed and empirically validated through structural equation modeling (SEM). It is confirmed in this study that organizations which have better dynamic social alignment on the operational level continuously support the execution of changing everyday business tasks. The results also confirmed the mediating role of business process performance between task support satisfaction (TSS) and organizational performance. The study reveals that business and IT professionals need to nurture and maintain dynamic mutual agreement regarding IS changes in order to improve performance. In this manner their organization would be more prepared for reconfiguration and transformation, vital for adjustment to rapidly changing environment.
Keywords: business-IT alignment; dynamic social alignment; IS change agreement; shared understanding; task support satisfaction; business process performance; organizational performance; IT business value.
The Influence Mechanism of Goal Content on Employees Ethical Sensitivity
by Dalong Zhang, Jian Zhang, Ying Zhang
Abstract: Ethical sensitivity is the initial logical component of ethical behavior. Only if individuals recognize the ethical problems in a situation can they make ethical judgments and perform ethical behaviors. Ethical sensitivity is affected by many factors. Therefore, to promote the ethical behavior of employees, it is necessary to explore the key factors of employees ethical sensitivity. Based on a framework of self-determination theory, this study analyzes the effects of goal contents on ethical sensitivity and the mediating role of basic psychological needs. A total of 149 employees were surveyed and the results demonstrate the following: (1) intrinsic goals are positively related to ethical sensitivity; (2) the intrinsic goals and basic psychological needs are significantly positively related; and (3) basic psychological needs fully mediate the relationship between intrinsic goals and ethical sensitivity. Finally, the practical contributions of the research and suggestions for future studies are discussed.

Competency-based Diagnosis for Interns-Quality Assessment Approach
by Tao-Ming Cheng, Hsing-Yu Hou, Rung-Ching Chen, Dinesh Agrawal, Ji-Yuan Lin
Abstract: In order to understand how the advantages of internship programmes influence the undergraduates, this study evaluated seniors experiences with the internship programme in marketing and logistics management department at the case university. Through the University Career and Competency Assessment Network (UCAN) system, we used Demings Plan-Do-Check-Action (PDCA) methodology to investigate the relationship between learning outcome, competency assessment, and curriculum improvement. Our study showed that after the internship, students professional and common competencies were improved and interns were satisfied with the programme. In professional competency, students get opportunities for direct learning and experience of product, price, promotion, and place. Among the eight common competencies, the highest score represents the Responsibility and Discipline. The satisfaction surveys showed that it is very important to offer a rich and sufficient curriculum design. Also, it was found that communication expression and job responsibility and discipline are best achieved by real-world training. This research fulfills objectives of the PDCA cycle and fits teaching and learning quality improvement.

Task complexity and rapport in Outsourced System Development
by Neeraj Parolia, Yuzhu Li, Stella Tomasi
Abstract: Little work exists to study the impact of context on offshore development teams for information systems development (ISD) projects. This study examines the role of rapport and the impact of task complexity to influence cohesion within offshore ISD project teams and their implications for team performance and work satisfaction from a social capital and interdependence perspective. 500 surveys were sent to randomly selected IS team members in India from IS outsourcing vendors located in India. A total of 194 responses were used in the PLS analysis. The empirical results show that task complexity and rapport had a positive and significant effect on task cohesion while task cohesion had a positive and significant effect on project performance and work satisfaction. This study demonstrates that the interdependence between task complexity and rapport among team members that can lead to shared understanding of the problems and approaches the team adopts, which eventually leads to successful outcomes. rn
Keywords: Rapport; task cohesion; Task complexity; Work satisfaction; Project performance.
Impact of eWOM and risk-taking in gender on purchase intentions: Evidence from Chinese social media
by Muhammad Sohaib, Peng Hui, Umair Akram
Abstract: Electronic word of mouth (eWOM) has become as one of the most influential marketing tools in social media. The purposefulness of this study is to investigate the relationship between eWOM and purchase intention in Chinese social media context. Numerous studies have strived to elaborate eWOM phenomenon but little effort has done to explore its determinants. Using elaboration likelihood model, present article discusses not only explores the determinants of eWOM i.e. argument quality, source credibility, and involvement, but also identifies the relationship for eWOM with purchase intention of customers. The article also differentiates the risk-taking attitude between genders. Data were collected through online survey from 428 social media users. The results confirmed that argument quality, source credibility, and involvement are key determinants of eWOM in social media that positively influence customers purchase intentions. Furthermore, risk-taking propensity sounds more strongly in males than females, and it significantly and positively moderates the relationship of eWOM with purchase intentions. Findings of this study have important practical implications for marketing practitioners in the Chinese social media environment. Marketers should devise the comprehensive distinct marketing plan for customers to get them involved in spreading eWOM that would enhance their purchase intentions.
Keywords: Social media; eWOM; Argument quality; Source credibility; Involvement; Risk-taking; Purchase intentions.
The Impacts of Digital Business Strategy on Firm Performance: the Mediation Analysis of E-collaboration Capability
by Maomao Chi, Xinyuan Lu
Abstract: Nowadays, digital technologies (e.g., big data, cloud and mobility) have changed the firms activities. Many firms begin to utilize digital resources to formulate and execute digital business strategy. However, there is little empirical research focusing on explaining this novel phenomenon. In this paper, we proposed a framework which describes the value creation and appropriation process of digital business strategy in the digital settings. Our research model is tested by survey data and financial data from a sample of 138 manufacturing firms which adopted e-selling process. The result provides strong supports to the proposed research model. In particular, we find that, as hypothesized, the impact of digital business strategy on firm performance is completely mediated by e-collaboration capability which is one kind of digital capabilities. Theoretical and practical implications of the research are discussed.
Keywords: digital business strategy; e-collaboration capability; mediation effects.
BPMN4VC-Modeller: easy-handling of Versions of Collaborative Processes using Adaptation Patterns
by Imen BEN SAID, Mohamed Amine Chaabane, Eric Andonoff, Rafik Bouaziz
Abstract: BPMN4VC is an extension of BPMN for modelling versions of collaborative processes, represented as collaborations in BPMN. BPMN4VC has been recommended to address collaborative process flexibility issue, which is an important problem that Business Process Management (BPM) systems must face before their definitive acceptance and use in companies. BPMN4VC meta-model supports static and dynamic aspects of collaboration versioning. Dynamic aspects of collaboration versioning include low-level operations supporting versioning management, a life cycle indicating when these operations can be performed, and adaptation patterns making the update of collaboration schema easier to perform. This paper revisits the dynamic aspects of BPMNVC and in particular the adaptation patterns, detailing their implementation and use with BPMN4VC-Modeller, which is an implementation of BPMN4VC on top of the well-known BPMN Modeller Eclipse plug-in. Finally, the paper reports on an evaluation of the adaptation patterns and of BPMN4VC-Modeller to prove the feasibility of the contribution.
Keywords: Collaborative Process. Process Flexibility. Version. Adaptation Patterns. BPMN4VC-Modeller.
Statistical Bug Localization by Supervised Clustering of Program Predicates
by Farid Feyzi, Saeed Parsa, Esmaeel Nikravan
Abstract: Regarding the fact that the majority of faults may be revealed as joint effect of program predicates on each other, a new method for localizing complex bugs of programs is proposed in this article. The presented approach attempts to identify and select groups of interdependent predicates which altogether may affect the program failure. To ﬁnd these groups, we suggest the use of a supervised algorithm that is based on penalized logistic regression analysis. To provide the failure context, faulty sub-paths are recognized as sequences of fault relevant predicates. Estimating the grouping effect of program predicates on the failure helps programmers in the multiple-bug setting. Several case studies have been designed to evaluate the proposed approach on well-known test suites. The evaluations show that our method produces more precise results compared with prior fault localization techniques.
