The tags and descriptions entered by video owners in video sharing sites are typically inadequate for retrieval purposes, yet the majority of video search still uses this text. This problem is escalating due to the ease with which users can self-publish videos, generating masses that are poorly labelled and poorly described. This thesis investigates how users tag videos and whether video tagging games can solve this problem by generating useful sets of tags. A preliminary study investigated tags in two social video sharing sites, YouTube and Viddler. YouTube contained many irrelevant tags because the system does not encourage users to tag their videos and does not promote tags as useful. In contrast, using tags as the sole means of categorisation in Viddler motivated users to enter a higher proportion of relevant tags. Poor tags were found in both systems, however, highlighting the need to improve video tagging. In order to give users incentives to tag videos, the VideoTag project in this thesis developed two tagging games, Golden Tag and Top Tag, and one non-game tagging system, Simply Tag, and conducted two experiments with them. In the first experiment VideoTag was a portal to play video tagging games whereas in the second experiment it was a portal to curate collections of special interest videos. Users preferred to tag videos using games, generating tags that were relevant to the videos and that covered a range of tag types that were descriptive of the video content at a predominately specific, objective level. Users were motivated by interest in the content rather than by game elements, and content had an effect on the tag types used. In each experiment, users predominately tagged videos using objective language, with a tendency to use specific rather than basic tags. There was a significant difference between the types of tags entered in the games and in Simply Tag, with more basic, objective vocabulary entered into the games and more specific, objective language entered into the non-game system. Subjective tags were rare but were more frequent in Simply Tag. Gameplay also had an influence on the types of tags entered; Top Tag generated more basic tags and Golden Tag generated more specific and subjective tags. Users were not attracted to use VideoTag by the games alone. Game mechanics had little impact on motivations to use the system. VideoTag used YouTube videos, but could not upload the tags to YouTube and so users could see no benefit for the tags they entered, reducing participation. Specific interest content was more of a motivator for use than games or tagging and that this warrants further research. In the current game-saturated climate, gamification of a video tagging system may therefore be most successful for collections of videos that already have a committed user base.

The Bronco Chase and arrest of O.J. Simpson for the murder of his ex-wife, Nicole Brown Simpson and her friend, Ronald Goldman, and his subsequent criminal trial became one of the most captivating, mass-mediated events of the last decade of the twentieth century. Simpson's iconic celebrity status and his race as an African-American inflamed the notoriety of the crime. An insatiable spectatorial desire for Simpson and narratives concerning his alleged involvement in the Brentwood murders engulfed the American public and American culture for thirty-two months. An excessive scrutiny of his identity by the media, law and order professionals and the populace generated a racially charged discursive cacophony. The memoir Simpson published during his remand to raise funds for his defense expenses, I Want to Tell You: My Response to Your Letters, Your Messages, Your Questions, allows for a productive critical study of everyday rhetoric and the commodity fetishism of celebrity. Released in late January 1995, during the first week of the prosecution�s opening statements in the criminal trial, I Want to Tell You was Simpson's first public comment following the nationally televised reading of his suicide note and his spectacular arrest on June 17, 1994. The intercalation of Simpson�s narrative utterance with 108 of the more than three hundred thousand letters he received from June to December 1994 as Los Angeles County Jail inmate 4013970 is a practical manifestation of the use value and exchange value of fame. The reciprocity of the epistolic, the phatic demands of address, the etiquette of fan mail and hate mail, the gift of the written text, vulnerable and resonant, reveal an adherence to the symbiotic dynamic of the celebrity-fan, writer-reader, dyadic relation and its currency. Plying his trade as idol of consumption, as spectacle, as genre, Simpson capitalised on the cultural condition of his name and his face as objects of desire. The racialised flesh of Simpson's African-American male body became a site and a sight for narrative and inscription within a pay-per-view marketplace of reification, prosopopoeia, gazeability and criminality.

El presente es un proyecto investigativo de carácter exploratorio con un enfoque descriptivo alrededor de un fenómeno poco estudiado: el homecasting. Se busca aportar en la construcción, definición y delimitación del fenómeno del homecastig a través de un estudio de caso en el cual se describen y analizan ejemplos específicos relacionados con sujetos, objetos y prácticas particulares, en torno a la producción casera audiovisual alojada en el portal YouTube. El proyecto, realizado entre los años 2009 y 2013 busca aplicar algunos conceptos y metodologías del estudio de la vida cotidiana y la antropología urbana al estudio de las interacciones en Internet, proponiendo un estudio de caso específico (pues los encontrados son más generales o teóricos y no se ocupan de asuntos particulares en relación al homecasting) aportando al campo comunicacional a través de una mirada transversal, que enfatiza en que lo audiovisual está en el centro de los cambios en el sentido de las experiencias estéticas contemporáneas.

The convergence of transport, communication, computing and positioning technologies has enabled a smart car revolution. As a result, pricing of roads based on telematics technologies has gained significant attention. While there are promised benefits, systematic disclosure of precise location has the ability to impinge on privacy of a special kind, known as location privacy. The aim of this thesis is to provide technical designs that enhance the location privacy of motorists without compromising the benefits of accurate pricing. However, this research looks beyond a solely technology-based solution. For example, the ethical implications of the use of GPS data in pricing models have not been fully understood. Likewise, minimal research exists to evaluate the technical vulnerabilities that could be exploited to avoid criminal or financial penalties. To design a privacy-aware system, it is important to understand the needs of the stakeholders, most importantly the motorists. Knowledge about the anticipated privacy preferences of motorists is important in order to make reasonable predictions about their future willingness to adopt these systems. There is limited research so far on user perceptions regarding specific payment options in the uptake of privacy-aware systems. This thesis provides a critical privacy assessment of two mobility pricing systems, namely electronic tolls and mobility-priced insurance. As a result of this assessment, policy recommendations are developed which could support a common approach in facilitating privacy-aware mobility-pricing strategies. This thesis also evaluates the existing and potential inferential threats and vulnerabilities to develop security and privacy recommendations for privacy-aware pricing designs for tolls and insurance. Utilising these policy recommendations and analysing user-perception with regards to the feasibility of sustaining privacy , and willingness to pay for privacy, two privacy-aware mobility pricing designs have been presented which bridge the entire array of privacy interests and bring them together into a unified approach capable of sustaining legal protection as well as satisfying privacy requirements of motorists. It is maintained that it is only by social and technical analysis working in tandem that critical privacy issues in relation to location can be addressed.

The dissertation explores factors influencing consumers' payments in anonymous Pay-What-You-Want (PWYW) pricing contexts. Consumers often pay more than zero when given the opportunity to self-determine payments. However, most PWYW research has focused on contexts where the possibility of social influence from a salesperson or clerk is present. I suggest that in anonymous exchange contexts where social pressure does not exist, consumers will nevertheless make voluntary payments greater than zero. The present research explores PWYW in anonymous purchase contexts. Results from eight studies indicate that PWYW payment amounts are affected by heuristics and biases. In Essay 1, the influence of reference price on PWYW payments is explored. Firm-provided external reference prices (ERPs) framed as injunctive norms (e.g., suggested price) and descriptive norms (e.g., average payment) caused anchoring effects on voluntary payments such that those with higher ERPs reported higher payments. Further, ERPs framed as descriptive (vs. injunctive) norms were more predictive of payment amounts, but only when the ERP is high. Recalling internal reference price information is more effortful than simply reacting to a firm-provided price. The possibility that decreased cognitive processing results in higher payments, violating the concept of self-interest primacy, is explored in Essay 2. Four studies manipulate processing styles and demonstrate that when consumers use more effortful cognitive processing, they tend to make lower PWYW payments. These results suggest that consumers are likely to rely on a normal price heuristic when using more superficial processing. The dissertation demonstrates the importance of reference price information and cognitive processing styles when voluntary anonymous payments are made anonymously. PWYW decisions are influenced by the exchange context and how the information is cognitively processed. At a theoretical level, the findings demonstrate that consumers make voluntary payments in the absence of social pressure and that those payments can be predictably influenced by features in the exchange setting. Finally, the research suggests that consumers who exert less cognitive effort in PWYW situations make higher payments. It therefore appears that the first instinct is not to act self-interestedly by making little or no payments, but rather payments seem to be guided by heuristic-based decision making. / 2016-09-29
