Vision 2020 - A whole life-cycle information management system for built environments

A whole life-cycle information management vision is proposed, the organizational requirements for the realization of the scenario is investigated. Preliminary interviews with construction professionals are reported. Discontinuities at information transfer throughout life-cycle of built environments are resulting from lack of coordination and multiple data collection/storage practices. A more coherent history of these activities can improve the work practices of various teams by augmenting decision making processes and creating organizational learning opportunities. Therefore, there is a need for unifying these fragmented bits of data to create a meaningful, semantically rich and standardized information repository for built environment. The proposed vision utilizes embedded technologies and distributed building information models. Two diverse construction project types (large one-off design, small repetitive design) are investigated for the applicability of the vision. A functional prototype software/hardware system for demonstrating the practical use of this vision is developed and discussed. Plans for case-studies for validating the proposed model at a large PFI hospital and housing association projects are discussed.

Managing groups of files in a rule oriented data management system (iRODS)

The iRODS system, created by the San Diego Supercomputing Centre, is a rule oriented data management system that allows the user to create sets of rules to define how the data is to be managed. Each rule corresponds to a particular action or operation (such as checksumming a file) and the system is flexible enough to allow the user to create new rules for new types of operations. The iRODS system can interface to any storage system (provided an iRODS driver is built for that system) and relies on its’ metadata catalogue to provide a virtual file-system that can handle files of any size and type. However, some storage systems (such as tape systems) do not handle small files efficiently and prefer small files to be packaged up (or “bundled”) into larger units. We have developed a system that can bundle small data files of any type into larger units - mounted collections. The system can create collection families and contains its’ own extensible metadata, including metadata on which family the collection belongs to. The mounted collection system can work standalone and is being incorporated into the iRODS system to enhance the systems flexibility to handle small files. In this paper we describe the motivation for creating a mounted collection system, its’ architecture and how it has been incorporated into the iRODS system. We describe different technologies used to create the mounted collection system and provide some performance numbers.

Sub-agent elements for control methods in multi-agent energy management system

Increased penetration of generation and decentralised control are considered to be feasible and effective solution for reducing cost and emissions and hence efficiency associated with power generation and distribution. Distributed generation in combination with the multi-agent technology are perfect candidates for this solution. Pro-active and autonomous nature of multi-agent systems can provide an effective platform for decentralised control whilst improving reliability and flexibility of the grid.

Measuring student perception and actual usage of online learning management system

Online learning management systems are in use to facilitate the face to face learning process in many universities. There are many variables that shape and influence a student’s perception of an online learning management system. This study investigates whether there is a relationship between the perception of a student regarding the learning management system and their actual usage of such system. It is believed to help better understand the student usage of online learning management system. An online questionnaire was published on a course management system for a selected subject and the student participation was voluntary. Results indicate that no significant relationship between the perception students had about the learning management system and the actual use of the system. Interestingly, a significant relationship was found between having internet access away from university and the student perception about the system. Students who had internet access away from university had better perception about the learning management system even though there was no significant difference in the level of online learning management system usage between the groups.

Cost function for sub-agent elements in multi-agent energy management system

Distributed generation plays a key role in reducing CO2 emissions and losses in transmission of power. However, due to the nature of renewable resources, distributed generation requires suitable control strategies to assure reliability and optimality for the grid. Multi-agent systems are perfect candidates for providing distributed control of distributed generation stations as well as providing reliability and flexibility for the grid integration. The proposed multi-agent energy management system consists of single-type agents who control one or more gird entities, which are represented as generic sub-agent elements. The agent applies one control algorithm across all elements and uses a cost function to evaluate the suitability of the element as a supplier. The behavior set by the agent's user defines which parameters of an element have greater weight in the cost function, which allows the user to specify the preference on suppliers dynamically. This study shows the ability of the multi-agent energy management system to select suppliers according to the selection behavior given by the user. The optimality of the supplier for the required demand is ensured by the cost function based on the parameters of the element.

Developing a knowledge management system using an ontological approach in global organisation

This paper introduces an ontology-based knowledge model for knowledge management. This model can facilitate knowledge discovery that provides users with insight for decision making. The users requiring the insight normally play different roles with different requirements in an organisation. To meet the requirements, insights are created by purposely aggregated transnational data. This involves a semantic data integration process. In this paper, we present a knowledge management system which is capable of representing knowledge requirements in a domain context and enabling the semantic data integration through ontology modeling. The knowledge domain context of United Bible Societies is used to illustrate the features of the knowledge management capabilities.

Beneath a learning management system: understanding the human information interaction in information systems

Studies on learning management systems have largely been technical in nature with an emphasis on the evaluation of the human computer interaction (HCI) processes in using the LMS. This paper reports a study that evaluates the information interaction processes on an eLearning course used in teaching an applied Statistics course. The eLearning course is used as a synonym for information systems. The study explores issues of missing context in stored information in information systems. Using the semiotic framework as a guide, the researchers evaluated an existing eLearning course with the view to proposing a model for designing improved eLearning courses for future eLearning programmes. In this exploratory study, a survey questionnaire is used to collect data from 160 participants on an eLearning course in Statistics in Applied Climatology. The views of the participants are analysed with a focus on only the human information interaction issues. Using the semiotic framework as a guide, syntactic, semantic, pragmatic and social context gaps or problems were identified. The information interactions problems identified include ambiguous instructions, inadequate information, lack of sound, interface design problems among others. These problems affected the quality of new knowledge created by the participants. The researchers thus highlighted the challenges of missing information context when data is stored in an information system. The study concludes by proposing a human information interaction model for improving the information interaction quality issues in the design of eLearning course on learning management platforms and those other information systems.

Mapping Educational Specialist knowHow (MESH): the building of a knowledge management system for research informed practice

In this invited article the authors present an evaluative report on the development of the MESHGuides project (http://www.meshguides.org/). MESHGuides’ objective is to provide education with an international knowledge management system. MESHGuides were conceived as research summaries for supporting teachers’ in developing evidence-based practice. Their aim is to enhance teachers’ capacity to engage actively with research in their own classrooms. The original thinking for MESH arose from the work of UK-based academics Professor Marilyn Leask and Dr Sarah Younie in response to a desire, which has recently gathered momentum in the UK, for the development of a more research-informed teaching profession and for the establishment of an on-line platform to support evidence-based practice (DfE, 2015; Leask and Younie 2001; OECD 2009). The focus of this article is on how the MESHGuides project was conceived and structured, the technical systems supporting it and the practical reality for academics and teachers of composing and using MESHGuides. The project and the guides are in the early stages of development, and discussion indicates future possibilities for more global engagement with this knowledge management system.

Environmental management system adoption by Australasian organisations: part 1: reasons, benefits and impediments

The decision to adopt environmental management system (EMS) and to develop effective implementation strategies has engrossed managers at all levels and in all types of organisations in recent years. Some organisations have claimed that environmental issues have been determining their  bottom-line and business performance in the market place. This paper is first part in the series focussing on the reasons for EMS implementation and the benefits and impediments associated with the process. Measures  commonly practised by organisations to overcome/address the  impediments are also presented in this paper. The findings of this paper are based on a questionnaire survey mailed to Australasian organisations on their experiences with ISO 14001 implementation and certification.

A study of the environmental management system (EMS) adoption process within Australasian organisations-2. Role of stakeholders

The importance of an Environmental Management System (EMS) for organisations is becoming widely known across all industrial sectors. EMS has brought both challenges and benefits for the organisations and these many-a-times are determined by the role played by the organisational stakeholders. Stakeholder is a broad term and can encompass a number of individual(s) or group(s) directly or indirectly impacted by organisational activities. This paper, second part in the series, focuses on the role of the stakeholders, primarily employees and suppliers during the EMS planning and implementation stages. It is based on the findings of the quantitative part of a large research project exploring the role of employees and suppliers, as organisational stakeholders, during the EMS adoption stages. A response rate of almost 50% was achieved from a questionnaire survey of ISO 14001 certified organisations in Australia and New Zealand. The key relationships existing between the organisations and stakeholder involvement and the benefits and impediments associated with the process have also been presented.

A framework for environmental management system adoption and maintenance : an Australian perspective

Purpose – The purpose of this paper is to present a framework for environmental management system (EMS) adoption which can be used by managers to enable them to achieve a faster, smoother, effective and sustainable EMS implementation. This is termed by the authors as “successful” EMS implementation.
Design/methodology/approach – The framework presented is based on an extensive field study conducted in Australia that included a questionnaire survey and in-depth interviews conducted with practitioners, the results of which have been reported in this and other journals.
Findings – The framework presented covers three distinct phases, namely development, certification and maintenance and continuous improvement. Preliminary assessment of this framework by a group of Australian experts that included four senior managers, one academic and one consultant suggests that this framework is a useful tool for implementing an effective EMS.
Practical implications – Each of the three phases of the framework provides a step-by-step approach and a sequential map towards a successful EMS implementation.
Originality/value – The framework has been developed from extensive fieldwork and has been validated by a group of “experts” which comprised of four industry practitioners, one management academic, and one EMS consultant. The framework provides a detailed understanding of the steps involved in the implementation, certification, and maintenance of EMS.

Integrated management system:the experiences of three Australian organisations

Purpose – Management systems and standards have become a key part of the organisation's lifeline and a prerequisite for survival in the twenty-first century. Systems for quality environmental and occupational health and safety (OHS) now form the three main pillars of the organisation, the fourth one being financial accounting. In light of the increasing pressure and demands from different stakeholders, it is becoming necessary for organisations to adopt the different systems/standards. However, to achieve the benefits from the implementation and subsequently maintenance of these systems it is only a practical and logical step that the existing management systems/standards be integrated into a single system.

Design/methodology/approach – This paper presents the experiences of three Australian-based organisations that have successfully undertaken the integration of their management systems/standards. Data for this paper were collected through in-depth interviews conducted with the managers responsible for quality, environment and OHS systems.

Findings – The interviews revealed a number of quantifiable and unquantifiable benefits experienced by the companies from operating one integrated system, such as saving of dollars, better utilisation of resources and improved communication across the organisation, to name a few. However, for the benefits to be realized it is essential that organisations are aware of the challenges and obstacles accompanying integration of systems/standards. If these challenges are not addressed early in the process they can delay the completion of the integration process.

Originality/value – Recommendations for other organisations contemplating integrating their management system include: obtaining commitment from the top management; having adequate resources to integrate the systems; having communication and training across the organisation in aspects of integration; and, last but not the least, having integrated audits. Implementation of these recommendations may vary from one organisation to another; however, it would result in lesser resistance for the organisations following them.

Environmental management system auditing within Australasian companies

Reviews the literature on environmental management auditing, and surveys 132 ISO 14001 certified organizations in Australia and in New Zealand. Identifies the main reason for internal environmental audit, and the most frequent actions that result from the audit process, such as formation of a preventive plan. Looks at review procedures by top management, and the frequency of audit. Reveals the length of time an audit takes and the method of documentation adopted, by different industries. Notes six major findings and recommends sharing the findings of audits with employees and  suppliers so that improvements can be identified and implemented.
