    This article presents a case study of the London suburb of Chipping Barnet to show how a spatial-morphological approach to tangible heritage challenges its archetypal image as an affluent commuter suburb by highlighting its resilience as a generative patterning of social space that has weathered successive phases of social change. We argue that the enduring spatial-morphological definition of Barnet as a local centre explains how it has been possible to preserve something less tangible—namely its identity as a suburban community. We show how Barnet’s street network constitutes community heritage through a combination of local- and wider-scale affiliations that have sustained diverse localised socio-economic activity over an extended period of time. Noting how local histories often go further than sociological studies in emphasising the importance of the built environment for indexing the effects of social change on everyday life, we draw on a range of archive sources including the analysis of historical maps using space syntax techniques, to reveal Barnet’s street network as a dialogue of both tangible and intangible heritages that are formative of a suburban community

    Building equitable literate futures : home and school computer-mediated literacy practices and disadvantage

    Full text link
    This paper examines the complex connections between literacy practices, the use of information and communication technologies (ICTs) and disadvantage. It reports the findings of a year-long study which investigated the ways in which four families use ICTs to engage with formal and informal literacy learning in home and school settings. The research set out to explore what it is about computer-mediated literacy practices at home and at school in disadvantaged communities that make a difference in school success. The findings demonstrate that the \u27socialisation\u27 of the technology - its appropriation into existing family norms, values and lifestyles - varied from family to family. Having access to ICTs at home was not sufficient for the young people and their families to overcome the so-called \u27digital divide\u27. Clearly, we are seeing shifts in the meaning of \u27disadvantage\u27 in a globalised world mediated by the use of new technologies. New definitions of disadvantage that take account not only of access to the new technologies but also include calibrated understandings of what constitutes the access are required. The article concludes that old inequalities have not disappeared, but are playing out in new ways in the context of the networked society.<br /

    Cultivating connections: Growing internationalization in your university

    Get PDF
    International student outreach should encompass all aspects of librarianship. A necessary step in this process includes aligning engagement efforts with those of the larger academic institution. At the University of Tennessee in Knoxville, one of the most prominent campus-wide initiatives has been making the campus “Ready for the World.” This paper outlines methods of integrating the library into the larger university outreach goals for internationalization, including the integration into existing programs, co-hosting international events, and offering independent library programs to serve international initiatives

    Cooperative strategies for pairwise secure communication channels in sensor networks

    Get PDF
    Establishing secure communication channels in sensor networks is made especially difficult because of low power resources, hostile environments, and wireless communication. The power requirements of traditional cryptographic methods create the need for alternative strategies for secure communication in sensor networks. This thesis explores key distribution techniques in sensor networks. Specifically, we study in depth one method that enables sensors to establish pairwise secure communication channels. This strategy relies on a cooperative set of peer sensors to construct a unique key between two sensors. We built a unique network simulator to test secure communication parameters in a typical deployment scenario. This research tests the strategy by which the cooperative set of sensors is chosen. The results demonstrate that a strategy favoring neighbor nodes consumes significantly less energy than other alternatives at the expense of vulnerability to geographically localized attacks

    Utilization of youth information sources for community security and socioeconomic development in Gwale Local Government Area of Kano State, Nigeria

    The continuous access to information sources among youths today in our dear structured communities is creating a conundrum on the very&nbsp; existence of the people and the general purpose of information usage. The study examines youth’s information sources as a phenomenon and its consequence on community security and socioeconomic development. This situational study applies Information Horizons theoretical bases to explain who a lazy worthless youth is, on one hand and the dynamism of their general information needs and seeking behaviour as its affecttheir community security and livelihood on the other hand. The study adopts mixed methodology and use descriptive research design approach to obtain vital information from the youths. The study area (Gwale Local Government) population is 362,059 and to determine the sample size of 300 respondents from the three wards (Kabuga, Dandago and Goron Dutse) Fischer’s formula was adopted, the study uses cluster and simple random sampling to obtain this representation from the population. Close and open ended structured questionnaires constructed along the theoretical frame were the main instruments used for data collection. The results obtained where presented using descriptive statistics of frequency and&nbsp; percentage distribution tables. The result shows that the dearth of well assessed information is sine-qua-non to poverty spread among youths and the state of poorly structured information feeders hampers the youth’s ability to understand the structure of their community security and equally contribute positively to its social balance and economic diversity for sustainable development. The potentials of technology should be harnessed by government at local level to design community base eplatforms, e-town hall meetings, e-social forums and social media integrating text, audio,&nbsp; video, audiovisual and other user graphic interface, where the government presence are guaranteed (e-governance and e-representation) with committed personnel to man the activities and provide all-round-current-information and access links and equally guide through its utilization. Newtrends in information service delivery are important considerations to satisfying youths information needs, the study concludes. Keywords: Youths, Information, Information need, Slouch and Socio-economic developmen

    Sviluppo di nuove funzioni per il supporto dell'algoritmo di routing OCGR nel simulatore ONE per reti DTN di tipo opportunistico

    Get PDF
    L'ambiente di ricerca di questa tesi è quello del Delay- and Disruption-Tolerant Networking (DTN), un'architettura di rete progettata per far fronte ai problemi che caratterizzano le cosiddette “challenged networks”: tempi di propagazione elevati, un alto tasso di pedita dei pacchetti e connessioni intermittenti. L'origine di questa architettura risiede nella generalizzazione dei requisiti identificati per Inter-Planetary Networking (IPN), una rete composta da sonde, stazioni spaziali e satelliti, ma sono state ampiamente studiate anche applicazioni terrestri come reti militari tattiche, reti di sensori, reti mobili ad-hoc etc.. Nelle comunicazioni nello spazio profondo i contatti tra i nodi sono deterministici (perché dovuti al moto dei pianeti e delle navicelle spaziali), a differenza delle reti terrestri nelle quali i contatti sono generalmente opportunistici (non noti a priori). Per tutte queste reti, l'impiego dei protocolli della suite TCP/IP risulta inefficace o inattuabile. Esistono diverse implementazioni dell'architettura DTN: DTN2, IBR-DTN e ION (Interplanetary Overlay Network), sviluppata da NASA/JPL, per applicazioni spaziali. All'interno di ION è presente l'algoritmo di routing detto Contact Graph Routing (CGR), progettato per operare in ambienti con connettività deterministica e una sua estensione per ambienti non deterministici detta Opportunistic Contact Graph Routing (OCGR). Per lo studio degli algoritmi di routing nelle reti DTN la “Helsinki University of Techology” ha sviluppato il simulatore “The ONE”, che implementa diversi modelli di moto, di generazione dei dati, e permette la visualizzazione in tempo reale tramite interfaccia grafica. L’obiettivo principale di questa tesi è stato quello di combinare in un unico pacchetto i contributi degli studenti dell’Università di Bologna che mi hanno preceduto lavorando sul tema dell’integrazione di CGR in The ONE
