I denna projektrapport sammanställs arbetet med att skapa webbplatsen www.mannesmusik.com. Resultatet är tänkt att bli en hemsida som riktar sig till elever i högstadiet. Syftet med projektet var att skapa en pedagogisk plattform för musik på internet. Webbplatsen innehåller grundläggande förklaringar för gitarr, piano och bas. Ett annat mål var att skapa en digital materialbank för egna kompskisser, noter och körarrangemang på webbplatsen. I arbetet med att jobba fram hemsidan har vissa digitala program använts. Hemsidan har producerats i publiceringsprogrammet Wordpress. I rapporten beskrivs processen med att arbeta i detta program som till stor del bygger på färdiga mallar. Ett annat program som använts är Paintbrush vilket är ett ritprogram som brukats för att skapa enkla och tydliga kompskisser med ackordtabeller för de olika instrumenten. Obligatorisk och fri vald litteratur (se litteraturlista) ligger till grund för en mer allmän pedagogisk och konstnärlig diskussion av projektet men också som musiker och musiklärare.

Over the past 10 years, internet use has become an integral part of adolescent socialization. Teenagers use the internet to communicate with known others as well as with strangers. They engage in online entertainment in the form of gaming and surfing the web. While adolescents mainly use the internet to maintain pre-existing friendships, some adolescents make close friendships online. They also encounter negativity online in the form of cyberbullying. Despite the pervasiveness of internet use, relatively little is known about long-term effects of internet activities on adolescent psycho-social adjustment. This group of studies aimed to identify change over time associated with various aspects of internet use. First, the long-term associations between different internet-based activities and adolescent social relationships were identified. Second, the differences between adolescents who form close internet-based friendships and those who do not were examined. Finally, the importance of internet-based bullying was identified. Overall, results suggest that while some internet-based activities are associated with increased positive effects, some internet activities are also associated with negative outcomes over the long term. Having close online friends as part of one’s peer group is associated with negative psychosocial factors. Cyberbullying was identified as a form of bullying that is associated with many important outcomes. The implications of these findings call for an increase in monitoring, involving not only supervision but direct communication, of adolescents’ internet activities, and increased communication in families about internet use. / Thesis (Ph.D, Psychology) -- Queen's University, 2008-08-27 21:52:03.178

An investigation into the nature of public space in the North American city, this research seeks establish a more appropriate approach to a complex situation. Due to the manner in which North America has developed, true public space is superseded by the dominance of the automobile and private commercial interests. When this condition is tempered with the proliferation of ICTs and internet technology issues of private and public inhabitation become paradoxical. As a result of this study a new navigational system and series of interventions are proposed. These interventions are offered as only one of an incalculable set of possibilities and hope to generate further dialogue.

Best effort networks fail to deliver the level of service emerging Internet applications demand. As a result many networks are being transformed to Quality of Service (QoS) networks, of which most are Differentiated Services (DiffServ) networks. While the deployment of such networks has been feasible, it is extremely difficult to overhaul the transport layer protocols such as Transmission Control Protocol (TCP) running on hundreds of millions of end nodes around the world. TCP, which has been designed to run on a best effort network, perform poorly in a DiffServ network. It fails to deliver the performance guarantees expected of DiffServ. In this thesis we investigate two aspects of TCP performance in a DiffServ network unaccounted for in previous studies. We develop a deterministic model of TCP that intrinsically captures flow aggregation, a key component of DiffServ. The other important aspect of TCP considered in this thesis is its' transient behavior. Using our deterministic model we derive a classical control system model of TCP applicable in a DiffServ network. Performance issues of TCP can potentially inhibit the adoption of DiffServ. A DiffServ network commonly use token buckets, that are placed at the edge of the network, to mark packets according to their conformance to Service Level Agreements (SLA). We propose two token bucket variants designed to mitigate TCP issues present in a DiffServ network. Our first proposal incorporates a packet queue alongside the token bucket. The other proposal introduces a feedback controller around the token bucket. We validate both analytically and experimentally the performance of the proposed token buckets. By confining our changes to the token bucket we avoid any changes at end-nodes. The proposed token buckets can also be incrementally deployed. Most part of the Internet still remains as a best effort network. However, most nodes run various QoS functions locally. We look at one such important QoS function, i.e. the ability to survive against flows that are non-responsive to congestion, the equivalent of a Denial of Service (DoS) attack. We analyze existing techniques and propose improvements.

Technological neutrality in law is, roughly, the idea that law should not pick technological winners and losers, that law should neither help nor hinder particular types of technological aItefacts. It has become an increasingly recognized principle in the international stage, adopted by courts, legislatures, governmental and inter-governmental organizations alike. The grounds on which the principle has been adopted, however, are yet to see more in-depth articulation. This thesis takes up the task of more rigorously questioning whether technological neutrality is a sound principle for law and policy making in the information age. It does so by asking both whether technological neutrality makes sense internally, as a coherent proposition of the institutional normative order, and externally, as an unsuspected manifestation of the much more established, if contested, idea of political neutrality. Internally, the thesis questions: i) the ability of the principle to itself enable law to survive technological change; ii) the coherence of excluding reasons concerning dimensions of technological altefacts beyond the utilitarian functions of these from incorporation by law; iii) the soundness of transforming an idea of vagueness into a general principle for law and policy making in the information age; iv) the extent to which technological neutrality fUlther exacerbates the already problematic idea of instrumentalism in law. Externally, after demonstrating the political contours of technological neutrality, the thesis questions: i) whether technological neutrality would be able to survive the challenges that have been levelled at political neutrality by authors of diverse theoretical affiliations; and ii) whether the normative articulation of new forms of authority in the background culture of the information environment calls on the state to protect personal autonomy in ways thl1t are incompatible with the exclusionary methodology of political neutrality. Technological neutrality, the thesis demonstrates, does not live up to these or other challenges that the thesis introduces.
