This article compares communication technologies within and across crises, using evidence from contemporary postings in 68,022 blogs and news feeds and using a semiautomatic method to detect words that increase in usage during a crisis. Three case studies from 2005 are used: the July 7 London attacks, the New Orleans hurricane, and the Pakistan-Kashmir earthquake. The results highlight the info...

social commerce, a new stream in e-commerce, enables hyper-informed consumers to support the businesses in new product development. hyper-informed consumers are the results of online communication provided by social media. these consumers have been empowered by web 2.0 technologies to have online communication, which drives value for the companies in new product development. trust is one the va...

The birth of virtual reality marked a new path forward and also gave a fresh view of reality, allowing alternative ‘readings’ of cultural heritage. This new way of representation and simulation was soon associated with the term virtual environment, used to indicate those interactive three-dimensional models that could be navigated and that simulated a place, building, or synthetic representatio...

Advancements in telecommunication services and networking, have remarkably improved information communication services. The growing need of proper and secure communication is based on using appropriate communication technologies to work effectively and efficiently to meet the objectives of the information users. For some time this has been a great problem. For example, if one element e.g. a cab...

We explore lexical choice in Natural Language Generation (NLG) by implementing a model that uses both context and frequency information. Our model chooses a lemma given a WordNet synset in the abstract representations that are the input for generation. In order to find the correct lemma in its context, we map underspecified dependency trees to Hidden Markov Trees that take into account the prob...

Physical violence against women is pervasive through out the world and domestic violence has been a longstanding issue in feminist activism and research. Yet, these experiences are often not represented in technological research or design. In the move to consider HCI at the margins, in this paper, we ask: how have ICTs affected the experiences of domestic violence survivors? We interviewed fema...

Study of the interference effects in the space-frequency domain is substantially different from the study in the space-time domain though the basic equations are similar in their form. Recently, there is been an increasing interest in the theoretical and experimental investigations of number of coherence phenomena in the spacefrequency domain [1,2]. As has already been amply discussed and demon...

In this paper we will describe an approach to evaluating learning technology which we have developed over the last twenty-five years, outline its theoretical background and compare it with other evaluation frameworks. This has given us a set of working principles from evaluations we have conducted at the Open University and from the literature, which we apply to the conduct of evaluations. Thes...

T HIS special issue includes seven interesting articles that tackle some of the existing challenges and design issues related to the use of RF and Communication Technologies for wireless implants. An in-body medical device is a miniature device that is inserted in the human body to collect physiological signals and images or to act like a prosthetic device restoring certain body functions. In o...
