    'When I click "ok" I become Sassy – I become a girl.' Young people and gender identity: Subverting the ‘body’ in massively multi-player online role-playing games

    This article is available open access through the publisher’s website through the link below. Copyright @ 2012 Taylor & Francis.This article explores young people's practices in the virtual spaces of online gaming communities. Based on a five-year ethnographic study of virtual worlds, it considers how young people construct and maintain identities within virtual social systems. In particular, the article discusses digital gender practices and considers the potential that these games offer for their young users to engage in alternate gender identities. We argue that these digital spaces offer spaces for the imagination and can enhance agency and, potentially, resistance. However, digital identity is simultaneously no ‘liberated space’ and it incorporates norms and practices that often mirror those of the material world. We argue that this ‘porosity’ is an important tool through which young people come to understand gender identity

    Progress in the development of a S RETGEM-based detector for an early forest fire warning system

    In this paper we present a prototype of a Strip Resistive Thick GEM photosensitive gaseous detector filled with Ne and ethylferrocene vapours at a total pressure of 1 atm for an early forest fire detection system. Tests show that it is one hundred times more sensitive than the best commercial ultraviolet flame detectors and therefore, it is able to reliably detect a flame of 1.5x1.5x1.5 m3 at a distance of about 1km. An additional and unique feature of this detector is its imaging capability, which in combination with other techniques, may significantly reduce false fire alarms when operating in an automatic mode. Preliminary results conducted with air filled photosensitive gaseous detectors are also presented. The approach main advantages include both the simplicity of manufacturing and affordability of construction materials such as plastics and glues specifically reducing detector production cost. The sensitivity of these air filled detectors at certain conditions may be as high as those filled with Ne and EF. Long term test results of such sealed detectors indicate a significant progress in this direction. We believe that our detectors utilized in addition to other flame and smoke sensors will exceptionally increase the sensitivity of forest fire detection systems. Our future efforts will be focused on attempts to commercialize such detectors utilizing our aforementioned findings.Comment: Presented at the International Conference on Micropattern gaseous detectors, Crete, Greece, June 200

    Reduction of Late Design Changes Through Early Phase Need Analysis

    Published and used by INCOSE with permission. Abstract. Contractors in the oil and gas industry are experiencing an increased pressure to deliver projects at a lower cost and at a shorter schedule. Extensive requirements combined with strict governing documents restrict project designs. Therefore, contractors need efficient governing processes that capture customers ’ needs and ensure that system requirements relates to these customer needs. In the execution phase of a project, the engineering degrees of freedom are limited. In the early project phase of concept and study, the basic design is established. The design freeze occurs in the tender phase, based on a best interpretation of customer needs. This causes any changes made in the execution phase to be costly and have the potential to impose severe subsequent consequences. Proper use of systems engineering ensures a minimal amount of late design changes. The most important systems engineering process in such a context, is the capturing of customer needs and definition of user requirements. We researched the processes used to capture system requirements today, and the potential impact of using systems engineering techniques for this purpose. We uncovered multiple gaps in the current process of capturing customer needs, which subsequently led to the definition of system requirements based on international standards and best practices, instead of actual needs. Our research also showed that with a process of capturing customer needs based on systems engineering techniques, as much as 92 % of the costs imposed by late design changes are avoidable

    Surveying Standard Model Flux Vacua on T6/Z2×Z2T^6/Z_2\times Z_2

    We consider the SU(2)LxSU(2)R Standard Model brane embedding in an orientifold of T6/Z2xZ2. Within defined limits, we construct all such Standard Model brane embeddings and determine the relative number of flux vacua for each construction. Supersymmetry preserving brane recombination in the hidden sector enables us to identify many solutions with high flux. We discuss in detail the phenomenology of one model which is likely to dominate the counting of vacua. While Kahler moduli stabilization remains to be fully understood, we define the criteria necessary for generic constructions to have fixed moduli.Comment: 30 pages, LaTeX, v2: added reference
