1	Community Wireless Networks : a case study of Austin, Texas Rock, Kathy 05 December 2013 (has links) Community Wireless Networks (CWNs) are a fairly new phenomenon. One of the first projects, NYC Wireless, started in 2001. These wireless initiatives are often a response to the lack of high-speed ubiquitous computing. Many of the first users, frustrated neighborhood “techies,” jerry rigged low cost WiFi antennas to rooftops and the side of buildings in order to access a high-speed broadband service. By doing this the wireless pioneers shared high speed wireless signals with neighbors and anyone within reach of their signal. As wireless computing became more popular, and it’s social and economic benefits more obvious, CWNs became an attractive alternative for many rural and low-income urban communities. Populations that had been overlooked by large cable and telephone service companies. The success of CWNs has paved the way for municipalities to build publicly supported wireless projects. Cable and telephone companies, major providers of broadband service, view municipal networks as unfair competition, and thus began the legislative battle over municipal wireless networks. The battle continues to wage. Cable and telephone companies have had some success at the state level and the federal debate is underway at this moment. Therefore, the purpose of this report is to understand the role Austin’s nonprofits play to ensure that high speed broadband access is made available for everyone and how lessons learned in Austin can be applied to other cities and locations around the country. The study found that Austin, compared to other cities of the same size, has a very small nonprofit community to addresses the issue of universal broadband access. Although the group is small, networking and mingling between community service organizations, the city government and wireless projects has created a community that effectively addresses the issue of high-speed access to the Internet. / text Community Wireless Networks CWN Broadband access Internet access Austin High speed broadband
2	Mathematische Remodellierung zur Erforschung der exakten Semantik einfacher konventioneller Notationssysteme Lepper, Markus, Oehler, Michael, Kinzler, Hartmuth, Trancón y Widemann, Baltasar 01 October 2024 (has links) Das Projekt semPart – Semantik der Partitur versucht, durch Übertragung von Methoden der Informatik auf die musikalische Notation exakte Aussagen über deren Semantik zu erzielen. Dies geschieht durch Remodellierung, also durch das Erstellen kleiner mathematischer Modelle, die jeweils das historisch-kulturell bestimmte Dekodieren von isolierten Parameter-Schichten eines Notates nachbilden. Erstes wichtiges Ergebnis ist, dass es in keinem Bereich jemals eine einzige ›richtige‹ Definition von Syntax und Semantik geben kann, sondern einen Katalog von vielfältigen theoretisch möglichen und in der Praxis auch angetroffenen Varianten. Diese sind durch ihre Remodellierung exakt identifizier- und benennbar; ihre Gesamtheit bildet ein Raster, durch das Notationsstile und -werkzeuge beschreib- und vergleichbar werden. Dieses Raster und die Remodelle sind besonders politisch wichtig, zur Förderung einer öffentlichen Diskussion von Notationssystemen und ihren Eigenschaften, da zunehmend die Arbeitsweise von digitalen Werkzeugen die notationelle Praxis zu überformen und zu filtrieren droht. / The project semPart – Semantics of the Musical Score tries to clarify the semantics of musical notation by applying methods from informatics. This is done by remodelling, i. e., constructing small mathematical models that mimic the mentally and culturally determined processes taking place when decoding isolated parameters in musical notation. The first important result is that there can never be one single ‘correct’ definition of semantics in any area but rather a catalogue of many theoretically possible variants encountered in practice. Through their remodelling, these can be precisely identified and named; their totality constitutes a classification grid applicable to styles, corpora, single scores and digital tools such as editors or encoding standards. This grid and the remodels are of particular political importance in promoting a public discussion on notation systems and their characteristics, given that the increasing use of digital processing systems threatens to over-shape and narrow down notational practice. info:eu-repo/classification/ddc/780 ddc:780
3	Can mindfulness enhance connectedness with nature? The case of in-depth nature experiences with adolescents McCloskey, Jake A. 03 May 2018 (has links) This thesis is an exploratory look into the use of mindfulness practice on in-depth nature experiences to determine if the practice has benefit to the participant, their outdoor experience, and overall connectedness with nature. An original research project examined three groups of adolescents from St. Michaels University School Outdoor Education program in Victoria, BC, Canada, as they hiked the Juan de Fuca trail. Two of the three groups undertook a simple mindfulness protocol to explore the outcomes. Based on participant-observation and interviews, mindfulness practice was determined to be a useful practice towards alleviating stress and anxiety associated with aspects of in-depth outdoor experiences, such as morning preparations. Participants who practiced mindfulness on the trip asked fewer questions about the future and remained present more often than those who did not practice mindfulness. A further finding was that there are aspects of mindfulness inherent in in-depth nature experiences, such as sitting around a fire. These inherent mindfulness moments should be encouraged as they provide benefit to trip experiences, and potentially towards greater connectedness with nature. Overall, this qualitative study suggests that mindfulness is a useful tool for the benefit of human well-being and nature connection. However, more research is needed to further identify the magnitude and mechanisms of the benefit. / Graduate mindfulness meditation sit spot mindfulness practice nature nature experience nature connection connectedness with nature human/nature connection nature association association with nature CWN nature affiliation biophilia nature deficit disorder attention restoration theory biophilia hypothesis psycho-evolutionary theory adolescent outdoor education nature education wilderness therapy adventure therapy qualitative nature experience in-depth nature experience stress-reduction anxiety reduction campfire hiking backcountry outdoor outdoors nature Mindfulness-based stress reduction MBSR
