When it comes to conserving electricity, it is crucial for
users to understand how much electricity is used by single appliances. However, the rather technical feed-
back in pure numbers and intangible units of existing
energy feedback systems is not appropriate for most users. To improve this situation, we present PowerPe-
dia, a system that aims at providing action guiding
feedback beyond pure consumption values. PowerPedia
enables users to identify and compare the consumption of their residential appliances to those of others. It thus helps users to better assess their electricity consump-
tion and draw effective measures to save electricity.
Returnable transport items (RTIs) are key elements for enabling a smooth flow of goods throughout supply chains. Despite their importance, RTIs can be prone to high loss and breakage rates. Today’s RTI management processes are rather inefficient and are based on estimates about when, where and how RTIs are utilised. This limited visibility inevitably causes the involved parties to feel less responsible for the proper management of RTIs. As a consequence, inefficiencies created by a single party can result in a significant cost burden for the whole supply chain. The goal of this paper is therefore to explore the impact of increased asset visibility on the RTI management process. We describe a solution based on Radio Frequency Identification (RFID) technology and quantify its financial impact from each individual stakeholder’s perspective. Our findings suggest that RFID can provide a powerful means to counter inefficiencies in the RTI management process and improve the overall effectiveness of the RTI supply chain network.
Purpose – The present study is concerned with the determinants of RFID adoption among a group of early standards adopters. Despite the extensive discussion of the technological characteristics and expected benefits of RFID in the literature, only little is known about the drivers and barriers of RFID implementations in practice. This holds particularly for the later stages of the adoption process after an initial decision in favor of the technology was made. This paper aims to fill this gap by an analysis of a set of factors on the adoption of RFID, which have been shown to be relevant for the adoption of other forms of IT, such as ERP systems and EDI.
Design/methodology/approach – Based on a review of prior works, this paper constructs and empirically tests a structural model including factors related to the technology, the organization, and its environment.
Findings – The results suggest that top management support, perceived technology costs, and forces within the supply chain exert a significant influence on the adoption process. The study also finds that benefit perceptions have a significant but negative influence, which might be explained by the different modes of adopting RFID. The influence of a number of other factors known from the literature could not be supported by the study.
Originality/value – Prior works considered factors influencing the initial adoption decision among non-adopters. In contrast with these, the focus is set on research on early adopters that have already made a decision in favor of RFID standards. The data underlying this study were collected from EPCglobal, an international association of RFID adopters covering the whole supply chain.
Several problems exist in accurately quantifying the greenhouse gases (GHG) which result from the production, transportation, usage, and recycling of products. We review in this paper the current attempts at measuring GHG emissions and investigate the potential of UbiComp technologies in improving the state of the art in carbon footprint calculation and in communicating the result to
consumers. This has potential benefits on consumer awareness and behaviour and can also foster competition among companies towards higher energy and resource efficiency.
In this paper, we investigate how RFID and NFC could improve current customs processes to fight illicit trade. During the import process, customs officers have to evaluate which consignments are inspected and, when an inspection takes place, whether intellectual property rights have been infringed. We propose and evaluate new micro processes that leverage the dualexistence of products and logistic units in order to enable easier, faster and more reliable inspection of goods. The impact of the improved processes is analyzed with an example case.
The strong effects of descriptive normative feedback (“how you compare to others”) on an individual’s electricity consumption have been documented in the IS literature. Here, we extend prior research on reference group effects (“whom to compare with”) by defining the relevance of the reference group in terms of similarity in contextual factors as opposed to personal characteristics. Specifically, we manipulate the spatial proximity of reference groups and test whether population density moderates the effects of feedback. In a field study with 560 energy customers, we find that reference groups that are close in terms of geographical proximity are more effective than more distant groups. However, population density does not moderate this effect. Designer of green information systems should therefore use reference groups that are close to the energy consumer with regard to geographical proximity, but they do not need to tailor the intervention to the energy consumer’s location.
This paper describes a field study to investigate whether and to what extent individuals conserve more electricity if they have the opportunity to signal their behavior to others in the online community. Moreover, the study intends to reveal how positive social sanctions (e.g., publicly rewarding people who reduce their energy consumption) and negative social sanctions (e.g., publicly warning people who increase their consumption) cause individuals to alter both their energy demand and their time dedicated to the online community. We discuss related work on identity disclosure in online communities, on promoting sustainable behavior with information systems, and on economic theory explaining the effects of prosocial motives on behavior. The study will be conducted as field experiment using an energy efficiency portal developed by us and operated by an Austrian utility company that currently facilitates 9,899 active users out of which 1,400 will be randomly selected as study participants.
In industries including aerospace, pharmaceuticals, and perishables, as covered in the preceding chapters, counterfeit trade has developed into a severe problem. While established security features such as holograms, micro printings, and chemical markers do not seem to efficiently avert trade in illicit imitation products, RFID technology, with its potential to automate product authentications, may become a powerful tool to enhance brand and product protection. The following contribution aims at structuring the requirement definition for such a system by providing a non-formal attack model, and outlines several principal approaches to RFID-based solutions.
The escalating rate of energy consumption underpins the need to set goals that promote a reduction in CO2 emissions. In 2011 the transport sector contributed 23% to the total EU CO2 emissions; road transport alone was responsible for 71% of this 23% compared to 12% from aviation transport. Corporate car drivers drive, on average, three times more than private car users in Europe (21,500 miles). An improvement in their fuel efficiency, by encouraging sustainable driving using eco-feedback technologies, has the potential to reduce CO2 emissions and promote fuel cost savings of 1% to 8%. This paper evaluates, through an explorative structured analysis, these findings further by defining recommendations for an organization intending to use eco-feedback technologies to reduce the overall corporate fleet's CO2 emission. The theoretical analysis of these findings, through the lens of the Feedback Intervention Theory and appraisal of corporate car drivers' extrinsic and intrinsic motivation, revealed that it is imperative to raise driver's awareness of their fuel consumption. Drivers' concerns regarding management monitoring leading to control and punishment, if their fuel efficiency has not improved, must be addressed. It is essential that an organizational roll-out is not associated with punishments, but focused on motivating employees by providing extrinsic motivation through realistic goal setting and constructive feedback.
