e-Business challenges and directions: important themes from the first ICE-B workshop

A three-day asynchronous, interactive workshop was held at ICE-B’10 in Piraeus, Greece in July of 2010. This event captured conference themes for e-Business challenges and directions across four subject areas: a) e-Business applications and models, b) enterprise engineering, c) mobility, d) business collaboration and e-Services, and e) technology platforms. Quality Function Deployment (QFD) methods were used to gather, organize and evaluate themes and their ratings. This paper summarizes the most important themes rated by participants: a) Since technology is becoming more economic and social in nature, more agile and context-based application develop methods are needed. b) Enterprise engineering approaches are needed to support the design of systems that can evolve with changing stakeholder needs. c) The digital native groundswell requires changes to business models, operations, and systems to support Prosumers. d) Intelligence and interoperability are needed to address Prosumer activity and their highly customized product purchases. e) Technology platforms must rapidly and correctly adapt, provide widespread offerings and scale appropriately, in the context of changing situational contexts

A service-oriented technical framework for the development of integrated education management information system

The increasing demand for education, especially tertiary education, has triggered a lot of challenges within the university system, especially in developing nations like Nigeria. These challenges include management and administration of the following: students’ enrolment, staff and students profile information, tuition fees payment, course registration, examination, and result processing, among others. The development of various types of Education Management Information Systems (EMIS) to alleviate these challenges has presented a more efficient means of optimising processes in the university systems. Thus, stakeholders within the university system: administrators, lecturers and students interact with the EMIS to ease their respective academic activities. However, these EMIS are designed, developed, and deployed with different application platforms and programming standards, which make it difficult for different EMIS to share information as they act as isolated information island. Thus, there is a challenge of data exchange in integrating different EMIS to achieve cross platform data exchange. Meanwhile, there are such initiatives on standard frameworks for the integration of disparate systems that are found in education institutions like the Education Management Information System Interoperability Framework (EMIF) and the School Interoperability Framework (SIF). However, the complexity in the mechanism for data exchange of these frameworks and the limited focus on the design structure of EMIS that can easily adapt and integrate limit their use in education institutions, especially those in developing countries with limited technical manpower and knowhow. In the search for a simplified framework that reconsider EMIS as an integrated system that can seamlessly exchange data, this research study involved the investigation, design, demonstration, and evaluation of a service-oriented technical framework for the development of integrated EMIS using the design science research methodology. This study, therefore, contributed to knowledge with the proposition of a technical framework that simplifies and standardizes the development of integrated EMIS that seamlessly exchange data among different functional modules. The technical framework is designed based on the identified layered conceptual components: a) Education Information Structure (EIS) that provides adaptable Central Information System (CIS) for handling the specific information requirements of different education systems with Access Control that provides a layer of security services to check and grant authorization and authentication access; b) Service-Oriented Design layer that handles integration of functional modules to connect with the EIS with service interfaces using Representational State Transfer Application Programming Interface (REST API); c) Demonstration Logic layer that recognizes the development platform and the flexibility of the programming logic to scale with new information requirements; d) Data Exchange Mechanism that provides a layer of standard data serialization format using Java Script Object Notation (JSON) to exchange data, through the RESTful API services, among functional modules in the Service-Oriented Design layer and the CIS in the EIS layer; e) Database System layer that handles data storage and requests from services. Thus, the framework makes key contributions with provision for customisation and multi-tenant cloud approach for adaptability and standardisation of the development of integrated EMIS to fit into different education systems. It was demonstrated on a web-based platform using the Laravel development platform that offer framework for rapid application development. The demonstration considered a case study approach, and the evaluation was based on expert reviews and comparative analysis within the context of the key requirements from the research findings. These requirements are: a) Adaptability that consider the suitability to fit into the specific information requirement of the different education systems; b) Maintainability that underscore the use of simplified common technologies that can be delivered within the knowledge of the EMIS developer; c) Standardization that check for the use of standard technologies and techniques; d) Scalability that consider provision for extension of the CIS and the functional modules to respond to changes in information requirements of the education system; e) Connectivity that benchmark access to shared data sources by the different functional modules of the integrated EMIS; f) Accessibility that benchmark usability of the platform to deliver user expectations on cross-platform data for presentation. In essence, the technical framework is appropriate for the development of an integrated EMIS that uses simplified technologies and techniques for achieving EMIS integration. While the framework addressed the integrated EMIS development that achieve seamless data exchange and scalability using the service endpoint extensions, the issues of optimizing the framework for enhanced security and performance are open to further research.School of ComputingPh.

Investigation and development of a tangible technology framework for highly complex and abstract concepts

The ubiquitous integration of computer-supported learning tools within the educational domain has led educators to continuously seek effective technological platforms for teaching and learning. Overcoming the inherent limitations of traditional educational approaches, interactive and tangible computing platforms have consequently garnered increased interest in the pursuit of embedding active learning pedagogies within curricula. However, whilst Tangible User Interface (TUI) systems have been successfully developed to edutain children in various research contexts, TUI architectures have seen limited deployment towards more advanced educational pursuits. Thus, in contrast to current domain research, this study investigates the effectiveness and suitability of adopting TUI systems for enhancing the learning experience of abstract and complex computational science and technology-based concepts within higher educational institutions (HEI)s. Based on the proposal of a contextually apt TUI architecture, the research describes the design and development of eight distinct TUI frameworks embodying innovate interactive paradigms through tabletop peripherals, graphical design factors, and active tangible manipulatives. These computationally coupled design elements are evaluated through summative and formative experimental methodologies for their ability to aid in the effective teaching and learning of diverse threshold concepts experienced in computational science. In addition, through the design and adoption of a technology acceptance model for educational technology (TAM4Edu), the suitability of TUI frameworks in HEI education is empirically evaluated across a myriad of determinants for modelling students’ behavioural intention. In light of the statistically significant results obtained in both academic knowledge gain (μ = 25.8%) and student satisfaction (μ = 12.7%), the study outlines the affordances provided through TUI design for various constituents of active learning theories and modalities. Thus, based on an empirical and pedagogical analyses, a set of design guidelines is defined within this research to direct the effective development of TUI design elements for teaching and learning abstract threshold concepts in HEI adaptations

Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm

Abstract— Online transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can’t store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system.
