An approach to faulty reader detection in RFID reader network

Radio Frequency Identification (RFID) technology is becoming increasingly popular as an automated tool for object monitoring and identification in a cost-efficient manner. RFID systems are made up of heterogeneous components consisting of both hardware and software. RFID components such as the readers are prone to failures with serious consequences to the overall system. Thus, issues such as reliability and dependability of RFID systems are receiving attention recently. This mandates fault management that includes monitoring the health of RFID readers and accessing the RFID reader configurations remotely. Therefore, an approach that detects the faulty readers with the aim to minimize the impacts of the faulty readers on the system reliability and dependability is of paramount importance. In this chapter, the authors discuss an approach to detect faulty readers in networked RFID system environments. Performance evaluation of the approach against other techniques is presented and shows that it performs reasonably well in the presence of faulty readers.

A security framework for networked RFID

In the last decade RFID technology has become a major contender for managing large scale logistics operations and generating and distributing the massive amount of data involved in such operations. One of the main obstacles to the widespread deployment and adoption of RFID systems is the security issues inherent in them. This is compounded by a noticeable lack of literature on how to identify the vulnerabilities of a RFID system and then effectively identify and develop counter measures to combat the threats posed by those vulnerabilities. In this chapter, the authors develop a conceptual framework for analysing the threats, attacks, and security requirements pertaining to networked RFID systems. The vulnerabilities of, and the threats to, the system are identified using the threat model. The security framework itself consists of two main concepts: (1) the attack model, which identifies and classifies the possible attacks, and (2) the system model, which identifies the security requirements. The framework gives readers a method with which to analyse the threats any given system faces. Those threats can then be used to identify the attacks possible on that system and get a better understanding of those attacks. It also allows the reader to easily identify all the security requirements of that system and identify how those requirements can be met.

Discovery of latent subcommunities in a blog's readership

The blogosphere has grown to be a mainstream forum of social interaction as well as a commercially attractive source of information and influence. Tools are needed to better understand how communities that adhere to individual blogs are constituted in order to facilitate new personal, socially-focused browsing paradigms, and understand how blog content is consumed, which is of interest to blog authors, big media, and search. We present a novel approach to blog subcommunity characterization by modeling individual blog readers using mixtures of an extension to the LDA family that jointly models phrases and time, Ngram Topic over Time (NTOT), and cluster with a number of similarity measures using Affinity Propagation. We experiment with two datasets: a small set of blogs whose authors provide feedback, and a set of popular, highly commented blogs, which provide indicators of algorithm scalability and interpretability without prior knowledge of a given blog. The results offer useful insight to the blog authors about their commenting community, and are observed to offer an integrated perspective on the topics of discussion and members engaged in those discussions for unfamiliar blogs. Our approach also holds promise as a component of solutions to related problems, such as online entity resolution and role discovery.

Social reader : following social networks in the wilds of the blogosphere

The social interactions manifest in blogs by the network of comments left by owners and readers are an under-used resource, both for blog pundits and industry. We present a web-based feed reader that renders these relationships with a graph representation, and enables exploration by displaying people and blogs who are proximate to a user's network. Social Reader is an example of Casual Information Visualization, and aims to help the user understand and explore blog-based social networks in a daily, real-life setting. A six week study of the software involving 20 users confirmed the usefulness of the novel visual display, via a quantitative analysis of use logs, and an exit survey.

Water in the Indic Traditions

The essay critically discusses the predominant role played by water in the lives of people from Vedic times to the present day, in the Hindu world. A number of ceremonies both happy or auspicious-making and secular have been associated with water. Several hymns of the Vedas, Brāhmanas, Mahābhārata, Āgamic and Purānic texts are drawn upon to bring out the legends and myths, and genuine beliefs, connected with water that underscore the sacred and profane, purificatory, healing and resuscitating dimensions of water. The essay treats readers to many ancient motifs concerning the pervasive value and utility of water. These comprise, variously, sacrifice, fertility rites, water-medium birth, divine metamorphosis, self-conceiving cosmic birth, totemism life-cycle rites, sanctifications, consecration and installation of icons and edifices, food rituals, monsoon rites, to pacifications, possession and exorcism, death, after-life and rebirth rituals. Reference is also made to the ecology of water resources, the economy of water scarcity, ‘war-wars’ or water imperialism, and water justice in the socio-political arenas of post independent India, in a rapidly liberalising and globalising world. In that regard practical applications of the knowledge-base are explored through the work of NGOs and Water Swamis in the subcontinent.

Book review : The making of the European Union : foundations, institutions and future trends

Whilst there are many books on the European Union (EU), this recently published book by four scholars is a comprehensive and important addition to the research on Europe. As the title of the book suggests, the EU is impacted by historical events and is shaped by future trends. The authors of this book include eight chapters on the EU that range from an analysis of the EU's development from a free trading area to having a common currency to how the EU is changing in terms of diversity and consumer trends. The book contains the most recent figures that are available on the EU and these figures are presented in useful tables to explain developments in the EU. This book stands out from the existing books on the EU by combining a cultural and historical analysis together with current discourse on the EU. The book is easy to read and is very suitable for both scholars, public policy practitioners and general readers who want a holistic book that incorporates a diverse range of topics on the EU.

The case of children's literature : colonial or anti-colonial?

Since Jacqueline Rose published The Case of Peter Pan in 1984, scholars in the field of children’s literature have taken up a rhetorical stance which treats child readers as colonised, and children’s books as a colonising site. This article takes issue with Rose’s rhetoric of colonisation and its deployment by scholars, arguing that it is tainted by logical and ethical flaws. Rather, children’s literature can be a site of decolonisation which revisions the hierarchies of value promoted through colonisation and its aftermath by adopting what Bill Ashcroft refers to as tactics of interpolation. To illustrate how decolonising strategies work in children’s texts, the article considers several alphabet books by Indigenous author-illustrators from Canada and Australia, arguing that these texts for very young children interpolate colonial discourses by valorising minority languages and by attributing to English words meanings produced within Indigenous cultures.

Professional education using e-simulations : benefits of blended learning design

The use of digital, Web-based simulations for education and training in the workplace is a significant, emerging innovation requiring immediate attention. A convergence of new educational needs, theories of learning, and role-based simulation technologies points to educators’ readiness for e-simulations. As modern e-simulations aim at integration into blended learning environments, they promote rich experiential, constructivist learning.

Professional Education Using E-Simulations: Benefits of Blended Learning Design contains a broad range of theoretical perspectives on, and practical illustrations of, the field of e-simulations for educating the professions in blended learning environments. Readers will see authors articulate various views on the nature of professions and professionalism, the nature and roles that various types of e-simulations play in contributing to developing an array of professional capabilities, and various viewpoints on how e-simulations as an integral component of blended learning environments can be conceived, enacted, evaluated, and researched.

Metadiscourse functions in English and Persian sociology articles : a study in contrastive rhetoric

This study on contrastive rhetoric reports on metadiscourse functions in sociology articles in Persian and English. The results have revealed a higher number of metadiscourse elements in the English texts. Among the different metadiscourse elements used, text connectors are the most frequently employed in both languages. Modality markers are the second most frequent in both languages although the English writers used nearly twice the number of these markers. Overall, it is found that the frequency of textual metadiscourse markers is greater than the interpersonal markers in both language samples. It was further revealed that the Persian writers of sociology texts are less interested in explicitly orienting the readers and some of the main points in an article, especially in the concluding section, are left for the readers to infer. This, we believe, is the result of less reliance on academic writing in the educational system of the country. Instead, the Iranians are largely encouraged to employ a flowery language and rhetoric to decorate their writing in their school years which makes them less attentive of their readers.

Learners' incidental vocabulary acquisition : a case on narrative and expository texts

This study was intended to determine whether or not the genre of a reading text affects the incidental vocabulary acquisition of L2 learners while reading. To this aim, 40 Iranian EFL students whose vocabulary knowledge was within a limited range (already determined by Nation’s Vocabulary Levels Test) were divided into two groups of 20 each for the reading sections. The Narrative Group comprised the participants who read the narratives, and the Expository Group were those who read the expository texts. Three types of vocabulary tests (i.e., Form recognition, Meaning translation and Multiple-choice items) were administered after the reading sessions to assess the incidental vocabulary gains of the participants. Overall, this study demonstrated the relative superiority of expository texts over narratives in terms of enhancing readers' incidental acquisition of unknown words. It is argued that depending on the genre of a text, readers will invest processing resources with different depths and varying degrees of cognitive elaboration for the task of comprehension.

Online communities and commercialization of Chinese internet literature

This article presents a case study on roles of online communities in development and commercialization of Chinese Internet literature (CIL). Online communities are widely used in ethnic Chinese communities for publication of CIL works. Uses of online communities in publication of CIL works enhance authors’ and readers’ experience and facilitate the growth of the CIL market. In turn, the growth of the CIL market creates new business opportunities that eventually lead to CIL commercialization. Evidences from the case show that the roles of online communities on CIL commercialization are much larger than simply being a new product development platform.
