In this paper we present a case study of kids’ appropriation of GarageBand digital music software to create an informal, ad hoc collaborative process. We argue that elements of the socio-spatial context of use combined with the software and the audio mode created a ‘safe’ space for collaboration and a powerful mode for informal creative exchange and feedback. We conclude with suggestions for...

Faceted navigation is a proven technique for supporting exploration and discovery within an information collection. The underlying data model is simple enough to make navigation understandable while at the same time rich enough to make navigation flexible in a wide range of domains. Nonetheless, there remain issues in both the presentation of navigation options in the interface and in how to...

Internet scamming strategies associated with West Africa typically involve the creation and deployment of fictional narratives depicting political turmoil, corruption, violence, poverty, and personal tragedy set in a variety of African nations. This article examines Internet scammers' complicity in promoting these creatively dramatic, yet stereotyped, representations of Africa and Africans. Their...

The Extensible Markup Language (XML), which just celebrated its 10th birthday, is one of the big success stories of the Web. Apart from basic Web technologies (URIs, HTTP, and HTML) and the advanced scripting driving the Web 2.0 wave, XML is by far the most successful and ubiquitous Web technology. With great power, however, comes great responsibility, so while XML's success is well...

Ubicomp research has spurred the exploration of more "natural" or "invisible" interfaces that can be seamlessly embedded into their environment. In this paper, we discuss the role such technology can play in augmenting existing creative practice to enhance the sharing of the handcraft process. We present the design and implementation of Spyn, a system for knitters to record, playback, and share...

Content delivery networks (CDNs) are a vital component of the Internet's content delivery value chain, servicing nearly a third of the Internet's most popular content sites. However, in spite of their strategic importance, little is known about the optimal pricing policies or adoption drivers of CDNs. We address these questions using analytic models of CDN pricing and adoption under Markovian...

User-directed routing technologies - that is, systems in which users choose their own routes through a communications network - have generated considerable interest in recent years. Despite their numerous theoretical advantages, ISPs have so far resisted these technologies, even as users have learned to capture some routing power through overlay networks. This study responds to this disconnect...

In a sensor network environment, elements such as message rate, message size, mote frequency, and message routing can reveal transactional data - that is, information about the sensors deployed, frequency of events monitored, network topology, parties deploying the network, and location of subjects and objects moving through the networked space. Whereas the confidentiality of network...

This paper describes characteristics of information and service design by exploring the needs and motivations of tourists. Tourists are expected to be important and demanding users of location-based services. They will need customized means to filter their experience of destinations, as well as ways to meaningfully participate in the creation of narratives and histories about different places....

Advances in technology are permitting broadband service providers to enter the residential video market. This has enabled effective competition in the delivery of wired video services, bringing a wider variety of offerings and lower prices. This study uses current population data along with demand and subscription rate data from our 2006 study to develop reasonable estimates of the effects of...

Computer users express a strong desire to prevent attacks and to reduce the losses from computer and information security breaches. However, security compromises are common and widespread and highly damaging. Next to attackers' increased sophistication, a root cause for the harm inflicted is that users often fail to optimally protect their resources or to recover gracefully from a security breach...

Competition to cable television as the dominant means of delivering video programming via wired infrastructures to the home is starting to emerge in several countries. A few areas have competitive overbuilds and in others innovative broadband service providers (BSPs) are using digital systems to deliver video services. The recent emergence of IPbased video technologies and BSPs has provided...

We present a simple linguistically-motivated method for characterizing the semantic relations that hold between two nouns. The approach leverages the vast size of the Web in order to build lexically-specific features. The main idea is to look for verbs, prepositions, and coordinating conjunctions that can help make explicit the hidden relations between the target nouns. Using these features in...
