Wearable learning tools

In life people must learn whenever and wherever they experience something new. Until recently computing technology could not support such a notion, the constraints of size, power and cost kept computers under the classroom table, in the office or in the home. Recent advances in miniaturization have led to a growing field of research in ‘wearable’ computing. This paper looks at how such technologies can enhance computer‐mediated communications, with a focus upon collaborative working for learning. An experimental system, MetaPark, is discussed, which explores communications, data retrieval and recording, and navigation techniques within and across real and virtual environments. In order to realize the MetaPark concept, an underlying network architecture is described that supports the required communication model between static and mobile users. This infrastructure, the MUON framework, is offered as a solution to provide a seamless service that tracks user location, interfaces to contextual awareness agents, and provides transparent network service switching

Commons and Cooperatives

In the last decade, the commons has become a prevalent theme in discussions about collective but decentralized control over resources. This paper is a preliminary exploration of the potential linkages between commons and cooperatives through a discussion of the worker cooperative as one example of a labour commons. We view the worker coop as a response at once antagonistic and accommodative to capitalism. This perspective is amplified through a consideration of five aspects of an ideal-type worker cooperativism: associated labour, workplace democracy, surplus distribution, cooperation among cooperatives, and, controversially, links between worker cooperatives and socialist states. We conclude by suggesting that the radical potential of worker cooperatives might be extended, theoretically and practically, by elaborating connections with other commons struggles in a process we term the circulation of the common

Automating Content Analysis of Video Games

Content analysis of video games tends to be an extremely arduous task, involving the collection of a very large quantity of data and statistics detailing the experiences of gameplay. Nevertheless, it is an important process that supports many business, policy, social, and scholarly activities related to the games industry. Consequently, supports are clearly necessary to facilitate content analysis procedures for video games. This paper discusses an innovative approach to automating content analysis for video games through the use of software instrumentation. By properly instrumenting video game software to enable data collection and processing, content analysis procedures can be either partially or fully automated, depending on the game in question. This paper discusses our overall approach to automation, as well as our experiences to date with Epic’s Unreal Engine. Sample results from initial experiments conducted so far are also presented. These results have been quite positive, demonstrating great promise for continued work in this area

Everyday graphic design

This paper explores a tension between the contemporary Graphic Designer David Carson and the 1960s artist Jacques Villeglé, an artist Carson has never heard of. We claim that Villeglé’s work celebrates the irregularities of what could be considered mundane ad hoc street performances. In contrast, Carson more or less detaches his work from that seamy reality of the banal by reducing the inherent complexity of the everyday into ideal assemblages of image-and-text. By highlighting this awkward difference between an ideal designerly intention and a grubbier everyday reality, we stimulate appetites for more realist-inspired discourses of graphic design

Mobilizing User-Generated Content For Canada’s Digital Advantage

Executive Summary: The goal of the Mobilizing User-Generated Content for Canada’s Digital Content Advantage project is to define User-Generated Content (UGC) in its current state, identify successful models built for UGC, and anticipate barriers and policy infrastructure needed to sustain a model to leverage the further development of UGC to Canada\u27s advantage. At the outset, we divided our research into three domains: creative content, small scale tools and collaborative user-generated content. User-generated creative content is becoming increasingly evident throughout the technological ecology through online platforms and online social networks where individuals develop, create and capture information and choose to distribute content through an online platform in a transformative manner. The Internet offers many tools and resources that simplify the various UGC processes and models. Social networking sites such as Facebook, Twitter, YouTube, Vimeo, Flickr and others provide functionality to upload content directly into the site itself, eliminating the need for formatting and conversion, and allowing almost instantaneous access to the content by the user’s social network. The successful sites have been able to integrate content creation, aggregation, distribution, and consumption into a single tool, further eroding some of the traditional dichotomies between content creators and end-users. Along with these larger scale resources, this study also treats small scale tools, which are tools, modifications, and applications that have been created by a user or group of users. There are three main categories of small scale tools. The first is game modifications, or add-ons, which are created by users/players in order to modify the game or assist in its play. The second is modifications, objects, or tools created for virtual worlds such as Second Life. Third, users create applications and tools for mobile devices, such as the iPhone or the Android system. The third domain considers UGC which is generated collaboratively. This category is comprised of wikis, open source software and creative content authored by a group rather than a sole individual. Several highly successful examples of collaborative UGC include Wikipedia, and open source projects such as the Linux operating system, Mozilla Firefox and the Apache platform. Major barriers to the production, distribution and aggregation of collaborative UGC are unduly restrictive intellectual property rights (including copyrights, licensing requirements and technological protection mechanisms). There are several crucial infrastructure and policies required to facilitate collaborative UGC. For example, in the area of copyright policy, a careful balance is needed to provide appropriate protection while still allowing downstream UGC creation. Other policy considerations include issues pertaining to technological protection mechanisms, privacy rights, consumer protection and competition. In terms of infrastructure, broadband internet access is the primary technological infrastructure required to promote collaborative UGC creation. There has recently been a proliferation of literature pertaining to all three of these domains, which are reviewed. Assessments are made about the most effective models and practices for each domain, as well as the barriers which impede further developments. This initial research is used as a basis for generating some tentative conclusions and recommendations for further research about the policy and technological infrastructures required to best mobilize and leverage user-generated content to create additional value in the digital economy internal and external to Canada. Policy recommendations based on this research focus on two principles: balancing the interest of both content owners and users, and creating an enabling environment in which UGC production, distribution, aggregation, and re-use can flourish

The use of columns of the zeolite clinoptilolite in the remediation of aqueous nuclear waste streams

Mud Hills clinoptilolite has been used in an effluent treatment plant (SIXEP) at the Sellafield nuclear reprocessing site. This material has been used to remove Cs-134/137 and Sr-90 successfully from effluents for 3 decades. Samples of the zeolite have been tested in column experiments to determine their ability to remove radioactive Cs+ and Sr2+ ions under increasing concentrations of competing ions, Ca2+, Mg2+, Na+ and K+. These ions caused increased elution of Cs+ and Sr2+. Ca2+, Mg2+ and K+ were more effective competitors than Na+. For Na+, it was found that if concentration was reduced, then column performance recovered rapidly.Peer reviewe

The biological origin of linguistic diversity

In contrast with animal communication systems, diversity is characteristic of almost every aspect of human language. Languages variously employ tones, clicks, or manual signs to signal differences in meaning; some languages lack the noun-verb distinction (e.g., Straits Salish), whereas others have a proliferation of fine-grained syntactic categories (e.g., Tzeltal); and some languages do without morphology (e.g., Mandarin), while others pack a whole sentence into a single word (e.g., Cayuga). A challenge for evolutionary biology is to reconcile the diversity of languages with the high degree of biological uniformity of their speakers. Here, we model processes of language change and geographical dispersion and find a consistent pressure for flexible learning, irrespective of the language being spoken. This pressure arises because flexible learners can best cope with the observed high rates of linguistic change associated with divergent cultural evolution following human migration. Thus, rather than genetic adaptations for specific aspects of language, such as recursion, the coevolution of genes and fast-changing linguistic structure provides the biological basis for linguistic diversity. Only biological adaptations for flexible learning combined with cultural evolution can explain how each child has the potential to learn any human language
