Moral guardians, industry protectionists and concerned citizens (each with their own political agendas) had, or many years, lobbied various Ministers of Customs to regulate the offensive material which flooded the local market-the war effectively opened a protectionist climate in which the local publishing industry nourished (Johnson-Woods Pulp Friction). Though westerns dominated at first, science fiction (i.e., futuristic stories, alternative histories, space exploration, time-travel past and future ) soon followed. Within the decaying and yellowed pages, contemporary readers have a glimpse into the culture of the 1950s and, amusing though some of the predictions are, the cultural and social critic gains some understanding of the anxieties and desires of post-World War II Australia.

It is technically feasible for mobile social software such as pairing or ‘matchmaking’ systems to introduce people to others and assist information exchange. However, little is known about the social structure of many mobile communities or why they would want such pairing systems. While engaged in other work determining requirements for a mobile travel assistant we saw a potentially useful application for a pairing system to facilitate the exchange of travel information between backpackers. To explore this area, we designed two studies involving usage of a low-fidelity role prototype of a social pairing system for backpackers. Backpackers rated the utility of different pairing types, and provided feedback on the social implications of being paired based on travel histories. Practical usage of the social network pairing activity and the implications of broader societal usage are discussed.

RFID is one of the contemporary technologies that has the potential to enable improved data gathering and cross-companies integration, and thus achieve cost efficiency. However, RFID has not yet become primary approach to collect data from the supply chain activities. This is partly due to (relative) high cost of implementation, partly due to technical deficiencies, as well as cross-company systems integration issues. This paper discusses a potential application area for RFID technology, which is environmentally sustainable supply chain management. The paper discusses the current practices in green supply chain management, and proposes possible applications of RFID enabling green supply chain management. The paper also proposes an idea of ad hoc RFID systems which are rapidly deployable and require minimal, if at all, pre-existing infrastructure. © 2010 IEEE.

This paper presents a Decision Support System framework based on Constrain Logic Programming and offers suggestions for using RFID technology to improve several of the critical procedures involved. This paper suggests that a widely distributed and semi-structured network of waste producing and waste collecting/processing enterprises can improve their planning both by the proposed Decision Support System, but also by implementing RFID technology to update and validate information in a continuous manner. © 2010 IEEE.

Competition in the 3PL market continues to intensify as providers compete to win and retain clients. 3PL providers are required to reduce costs while offering tailored innovative logistical solutions in order to remain competitive. 3PL providers can reduce costs through the consolidation of assets and introduction of cross-docking activities. Innovative logistical services can be tailored to each client via the introduction of real-time data updates. This paper highlights that RFID enabled RTE can assist in improvements of both these areas through increased network visibility. A framework is presented where the 3PL provider focuses on asset reduction, asset utilisation, real-time data employment and RTE cycle time reduction in order to enhance competitiveness. © 2011 IEEE.

This paper aims to discuss the recent literature on Radio Frequency Identification (RFID) and reverse logistics (RL). Particular attention is applied to the bullwhip effect and its increase as RL activities are integrated into the supply chain. RFID is investigated as a tool to assist with integrating reverse and forward logistics into a seamless supply chain and reduce the bullwhip effect. However, further research is required within this area and in particular the return on investment for RFID-enabled integrated systems.

Warehouse is an essential component in the supply chain, linking the chain partners and providing them with functions of product storage, inbound and outbound operations along with value-added processes. Allocation of warehouse resources should be efficient and effective to achieve optimum productivity and reduce operational costs. Radio frequency identification (RFID) is a technology capable of providing real-time information about supply chain operations. It has been used by warehousing and logistic enterprises to achieve reduced shrinkage, improved material handling and tracking as well as increased accuracy of data collection. However, both academics and practitioners express concerns about challenges to RFID adoption in the supply chain. This paper provides a comprehensive analysis of the problems encountered in RFID implementation at warehouses, discussing the theoretical and practical adoption barriers and causes of not achieving full potential of the technology. Lack of foreseeable return on investment (ROI) and high costs are the most commonly reported obstacles. Variety of standards and radio wave frequencies are identified as source of concern for decision makers. Inaccurate performance of the RFID within the warehouse environment is examined. Description of integration challenges between warehouse management system and RFID technology is given. The paper discusses the existing solutions to technological, investment and performance RFID adoption barriers. Factors to consider when implementing the RFID technology are given to help alleviate implementation problems. By illustrating the challenges of RFID in the warehouse environment and discussing possible solutions the paper aims to help both academics and practitioners to focus on key areas constituting an obstacle to the technology growth. As more studies will address these challenges, the realisation of RFID benefits for warehouses and supply chain will become a reality.

In recent years the increased interest in introducing radio frequency technology (RFID) in warehousing was observed. First adopters of RFID reported numerous benefits, which included: reduced shrinkage, real-time tracking and better accuracy of data collection. Along with the academic and industrial discussion on benefits which can be achieved in RFID enabled warehouses there are reports on issues related to adoption of RFID technology in warehousing. This paper reviews results of scientific reports of RFID implementation in warehouses and discusses the adoption barriers and causes of not achieving full potential of the technology. Following adoption barriers are identified and set in warehousing context: lack of forseeable return on investment (ROI), unreliable performance of RFID systems, standarisation, integration with legacy systems and privacy/security concerns. As more studies will address these challenges, the realisation of RFID benefits for warehouses will become reality.

In recent years the applications of radio frequency identification technology (RFID) in warehousing have gained a great amount of attention as it is a challenging and dynamic environment. Analysing a receiving operation of third party logistic (3PL) operator running a tyre distribution centre, this paper presents a case study of RFID application in the warehouse. The receiving process is enhanced with the RFID technology, which provides contactless identification, less manual data entry errors, instant stock management. Moreover, these benefits could be maximised by the proposed use of the RFID generated data in accounting of costs and services, which is a novel application of the RFID technology.

Radio-frequency identification technology (RFID) is a popular modern technology proven to deliver a range of value-added benefits to achieve system and operational efficiency, as well as cost-effectiveness. The operational characteristics of RFID outperform barcodes in many aspects. Despite its well-perceived benefits, a definite rationale for larger scale adoption is still not so promising. One of the key reasons is high implementation cost, especially the cost of tags for applications involving item-level tagging. This has resulted in the development of chipless RFID tags which cost much less than conventional chip-based tags. Despite the much lower tag cost, the uptake of chipless RFID system in the market is still not as widespread as predicted by RFID experts. This chapter explores the value-added applications of chipless RFID system to promote wider adoption. The chipless technology's technical and operational characteristics, benefits, limitations and current uses will also be examined. The merit of this chapter is to contribute fresh propositions to the promising applications of chipless RFID to increase its adoption in the industries that are currently not (or less popular in) utilising it, such as retail, logistics, manufacturing, healthcare, and service sectors. © 2013, IGI Global.
