Transactive Memory Systems (TMS) are important cognitive constructs to share knowledge and control and coordinate interdependent tasks in teams. The construction of Transactive Memory Systems involves a number of key phases that lead up to the actual formation of a team’s TMS. In particular, the development of Task-Expertise-People (TEP) units, form an essential part of the development of a team’s Transactive Memory System. At this stage very little is known of how Task- Expertise-People units are formed in virtual teams. This paper addresses this problem by following an inductive, quantitative method to develop a measurement scale for TEP ...


A Methodology For Bridge Condition Evaluation, Maria Rashidi, Peter Gibson Jan 2012

A Methodology For Bridge Condition Evaluation, Maria Rashidi, Peter Gibson

Faculty of Engineering and Information Sciences - Papers: Part A

Due to the substantial role of bridges in transportation networks and in accordance with the limited funding for bridge management, remediation strategies have to be prioritised. A conservative bridge assessment will result in unnecessary actions, such as costly bridge strengthening or repairs. On the other hand, any bridge maintenance negligence and delayed actions may lead to heavy future costs or degraded assets. The accuracy of decisions developed by any manager or bridge engineer relies on the accuracy of the bridge condition assessment which emanates from visual inspection. Many bridge rating systems are based on a very subjective procedure and are ...


Beyond Simple Classifications: Contemporary Information Systems Development Projects As Complex Adaptive Systems, Karlheinz Kautz Jan 2012

Beyond Simple Classifications: Contemporary Information Systems Development Projects As Complex Adaptive Systems, Karlheinz Kautz

Faculty of Engineering and Information Sciences - Papers: Part A

Contemporary Information Systems Development (ISD) takes place in a dynamic environment and is generally acknowledged as a complex activity. We investigate whether complex adaptive systems (CAS) theory is relevant as a theoretical foundation for understanding ISD, and if so, what kind of conception can be achieved by utilizing the theory? We introduce key CAS concepts and describe an emergent method framework for understanding ISD. Extending existing research, our main contribution is twofold: We first show how CAS and CAS principles are advantageous for comprehending and organizing ISD in general, beyond any particular development approach chosen for the execution of a ...

Social Implications Of Technology: The Past, The Present, And The Future, Karl Stephan, Katina Michael, M. G. Michael, Laura Jacob, Emily Anesta Jan 2012

Social Implications Of Technology: The Past, The Present, And The Future, Karl Stephan, Katina Michael, M. G. Michael, Laura Jacob, Emily Anesta

Faculty of Engineering and Information Sciences - Papers: Part A

The social implications of a wide variety of technologies are the subject matter of the IEEE Society on Social Implications of Technology (SSIT). This paper reviews the SSIT’s contributions since the Society’s founding in 1982, and surveys the outlook for certain key technologies that may have significant social impacts in the future. Military and security technologies, always of significant interest to SSIT, may become more autonomous with less human intervention, and this may have both good and bad consequences. We examine some current trends such as mobile, wearable, and pervasive computing, and find both dangers and opportunities in ...

A Sociomaterial Approach To Co-Creating Rfid Value In A Multi-Firm Supply Chain Knowledge Sharing Einvironment: A Longitudinal Case Study, Akemi T. Chatfield, Samuel F. Wamba

Faculty of Engineering and Information Sciences - Papers: Part A

Orlikowski and Lacono (2001, p. 132) aptly argue that IT artifacts, particularly distributed network technology applications, including RFID, "do not provide the same material and cultural properties in each local time or context of use." A sociomaterial theory suggests the importance of adopting an integrative approach to study the social and material effects when examining IT benefits realization. While much has been written about the high potential of RFID as a new class of strategic enterprise information systems, the early adopters of RFID and researchers still have to answer the question on how to co-create the business value of RFID ...

Order-4 Quasi-Orthogonal Cooperative Communication In Stfc Mb-Ofdm Uwb, Zixuan Lin, Le Chung Tran, Farzad Safaei, Tadeusz A. Wysocki

Faculty of Engineering and Information Sciences - Papers: Part A

Recently, cooperative communication and Space-Time-Frequency-Codes (STFCs) have been introduced into the Multiband OFDM Ultra-Wideband (MB-OFDM UWB) to improve the reliability, data rate and system capacity. This paper proposes a cooperative communication scheme for a four source node MB-OFDM UWB system using Quasi-Orthogonal STFCs, which is referred to as order-4 Quasi-Orthogonal Cooperative Communication Scheme (4-QOCCS). Simulation results show that the proposed 4-QOCCS provides significantly better error performance over the conventional MB-OFDM UWB and our order-2 Orthogonal Cooperative Communication Scheme (2-OCCS) using the Alamouti STFCs, and even better than the order-4 Orthogonal Cooperative Communication Scheme (4-OCCS), which we have been recently proposed ...

Faculty of Engineering and Information Sciences - Papers: Part A

Background: The English National Health Service's (NHS) Stop Smoking Services (SSSs) constitute one of the most highly developed behavioural support programmes in the world. However, there is significant variation in success rates across the approximately 150 services, some of which may be due to variation in practice. This study aimed to assess these differences in practice.

Methods: Two online surveys were administered. All commissioners (people who purchase services for the NHS) and managers (those who run the services) of NHS SSSs in England were invited to participate. Items included details of current practices and services provided, what informed the ...
