The following study used politeness theory to explore the impact of simultaneously engaging in a face to face conversation and a text message conversation. Specifically the study used Brown and Levinson’s (1978, 1987) five original politeness strategies to see whether strategy choice (in the face to face conversation) impacts the face threat present in engaging in multiple conversations. Multivariate analysis of covariance was used to understand the impact different politeness strategies had on the following variables: conversational appropriateness, relational/social appropriateness, immediacy, attentiveness, and politeness. Findings show that when a face to face partner ignores (no verbal/nonverbal politeness) a text message interruption the partner is seen as more relational/socially appropriate, immediate, attentive, and polite. Findings also indicate that aside from ignoring the text message, politeness messages that acknowledge the text message interruption and offer a relevant verbal message are viewed as more relationally/socially appropriate, immediate, attentive, and polite than those that indirectly deal with the text interruption. This study partially supports the popular belief that texting in the presence of others violates face to face conversational expectations and is perceived as “rude.” However, future studies need to look at the role and influence mediated conversational expectations play in overall conversational expectations.

The proliferation of mobile devices has resulted in the creation of an unprecedented amount of context about their users. Furthermore, the era of the Internet of Things (IoT) has begun and it will bring with it even more context and the ability for users to effect their environment through digital means. Applications that exist in the IoT ecosystem must treat context as a first class citizen and use it to simplify what would otherwise be an unmanageable amount of information. This thesis proposes the use of context to build a new class of applications that are focused on enhancing normal human behaviour and moving complexity away from the user. We present Yakkit—a location based messaging application that allows users to communicate with others nearby. The use of context allows Yakkit to be used without the creation of a login or a profile and enhances the normal way one would interact in public. To make Yakkit work we explore different ways of modelling location context and application deployment through experimentation. We model location in an attempt to predict a user’s final destination based on their current position and the trajectories of past users. Finally, we experiment deploying the Yakkit service on different servers to observe the effect of distance on the message transit time of Yakkit messages. / Graduate / przemek@uvic.ca

In this study we will explore impact exposure to brands references in music videos may have on the development of consumers’ brand knowledge. We assert that an understanding of this relationship is a function of both executional elements of the message and the intervening effects of select individual-difference factors. This dissertation applies social cognitive theories, the cultivation hypothesis, attribution theory and the elaboration likelihood model to develop the set of hypotheses. This dissertation seeks to provide initial evidence regarding the key factors brand managers and music executives must be aware of when implementing music video brand placements. A conceptual model of music video brand placement is presented and evaluated utilizing qualitative and quantitative techniques. The qualitative methodology employs real music fans as informants and music videos as stimuli in developing an understanding of the relationship consumers have with music as well as their reactions to music videos. The quantitative methodology uses an original music video as the stimulus, real music fans as respondents and a real-time on-line survey to measure the relationship among the variables. Study findings support the ability of music videos to impact extra-musical consumption and provide early evidence regarding factors important to understanding consumers’ responses to music video brand placements.

Text communication is often perceived as lacking some components of communication that are essential in sustaining interaction or conversation. This interaction incoherency tends to make text communication plastic. It is traditionally devoid of intonation, pitch, gesture, facial expression and visual or auditory cues. Nevertheless, Instant Messaging (IM), a form of text communication is on the upward uptake both on PCs and on mobile handhelds. There is a need to rubberise this plastic text messaging to improve co-presence for text communications thereby improving synchronous textual discussion, especially on handheld devices. <br /> <br /> One element of interaction is gesture, seen as a natural way of conversing. Attaining some level of interaction naturalism requires improving synchronous communication spontaneity, partly achieved by enhancing input mechanisms. To enhance input mechanisms for interactive text-based chat on mobile devices, there is a need to facilitate gesture input. Enhancement is achievable in a number of ways, such as input mechanism redesigning and input offering adaptation. This thesis explores affective gesture mode on interface redesign as an input offering adaptation. This is done without a major physical reconstruction of handheld devices.<br /> <br /> This thesis presents a text only IM system built on Session Initiation Protocol (SIP) and SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE). It was developed with a novel user-defined hotkey implemented as a one-click context menu to &ldquo / fast-track&rdquo / text-gestures and emoticons.<br /> <br /> A hybrid quantitative and qualitative approach was taken to enable data triangulation. Results from experimental trials show that an Affective Gesture (AG) approach improved IM chat spontaneity/response. Feedback from the user trials affirms that AG hotkey improves chat responsiveness, thus enhancing chat spontaneity.

Mobile banking is an application of mobile computing which provides customers with the support needed to be able to bank anywhere, anytime using a mobile handheld device and a mobile service such as text messaging (SMS). Mobile banking removes space and time limitations from banking activities such as checking account balances, or transferring money from one account to another. In recent research and studies it was found that while mobile banking and more specifically SMS-based mobile banking applications have become popular in some countries and regions, they were still not widely used. This study identifies and investigates the factors which influence customers’ decision to use a specific form of mobile banking, and specifically focuses on the evaluation of SMS-based mobile banking in the context of New Zealand. The research model includes the basic concepts of the Technology Acceptance Model (TAM), as well as some constructs derived through a focus group discussion. The model is tested to determine its predictive power with respect to individual’s behaviour when considering the use of SMS-based mobile banking. A survey questionnaire was developed and employed to collect data from 250 AUT university students in New Zealand. The results of the data analysis contributes to the body of knowledge in the area by demonstrating that context specific factors such as service quality and service awareness are influencing user perceptions about the usefulness of SMS mobile banking which in turn affect intention to use and adoption. Secondly, the study demonstrates, on the example of SMS-based mobile banking, how a hybrid approach involving qualitative data collection and a subsequent quantitative survey can help investigate how user perceptions about usefulness and ease of use are formed. Although the study has its limitations, the implications of the results allow providing practical recommendations to the banking industry, and directions for further work.

Magister Scientiae - MSc / Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits from new services. With the rapidly growing trend toward LBS, there is a need for standard LBS protocols. This thesis started with introducing the Internet Engineering Task Force GEOPRIV working group, which endeavors to provide standard LBS protocols capable of transferring geographic location information for diverse location-aware applications. Through careful observation, it was found that Session Initiation Protocol (SIP) is well suited to the GEOPRIV requirements. The aim of this research was therefore to explore the possibility of the integration of LBS and the SIP protocol and, to some extent fulfill the GEOPRIV requirements. / South Africa

abstract: Background: This study examines how pro-vaccine flu messages, guided by the Extended Parallel Process Model (EPPM), affect parents’ intentions to vaccinate their children. Methods: Parents of children six months to five years old (N = 975) were randomly exposed to one of four high-threat/high-efficacy messages (narrative, statistical, combined, control) and completed a follow-up survey. Differences between message conditions were assessed with one-way ANOVAs, and binary logistic regressions were used to show how constructs predicted intentions. Results: There were no significant differences in the ANOVA results at p = .05 for EPPM variables or risk EPPM variables. There was a significant difference between message conditions for perceived manipulation (p = 0.026), authority, (p = 0.024), character (p = 0.037), attention (p < .000), and emotion (p < .000). The EPPM model and perceptions of message model (positively), and the risk EPPM model and fear control model (negatively), predicted intentions to vaccinate. Significant predictor variables in each model at p < .05 were severity (aOR = 1.83), response efficacy (aOR = 4.33), risk susceptibility (aOR = 0.53), risk fear (aOR = 0.74), issue derogation (aOR = 0.63), perceived manipulation (aOR = 0.64), character (aOR = 2.00), and personal relevance (aOR = 1.88). In a multivariate model of the significant predictors, only response efficacy significantly predicted intentions to vaccinate (aOR = 3.43). Compared to the control, none of the experimental messages significantly predicted intentions to vaccinate. The narrative and combined conditions significantly predicted intentions to search online (aOR = 2.37), and the combined condition significantly predicted intentions to talk to family/friends (aOR = 2.66). Conclusions: The EPPM may not be effective in context of a two-way threat. Additional constructs that may be useful in the EPPM model are perceptions of the message and fear control variables. One-shot flu vaccine messages will be unlikely to directly influence vaccination rates; however they may increase information-seeking behavior. The impact of seeking more information on vaccination uptake requires further research. Flu vaccine messages should be presented in combined form. Future studies should focus on strategies to increase perceptions of the effectiveness of the flu vaccine. / Dissertation/Thesis / Doctoral Dissertation Public Health 2015

A maneira como percebemos visualmente o entorno afeta nosso próprio conhecimento do mesmo como um conceito de realidade. Este olhar, no entanto, não é influenciado apenas pelas peculiaridades físicas da visão humana ou por um conceito de subjetividade de um único indivíduo; ele é resultante de um determinado contexto social, cultural e tecnológico. Paralelamente são estes os fatores condicionantes que moldam a linguagem--verbal e visual--de um coletivo. Estas linguagens, por sua vez, delimitam aquilo que sabemos ou percebemos do mundo, pois são codificações que transformam os fênomenos e manifestações em conceitos transmissíveis por seus respectivos mecanismos de sintaxe. Entende-se que toda forma de linguagem criada pelo ser humano é um exercício de analogia da fenomenologia do cosmos. / The way we visually perceive the environment affects our own concept of reality. Sigh, however, is not only influenced by physical peculiarities of human\'s vision neither by one\'s concept of subjectivity; It is the result of a particular social, cultural and technological context. At the same time, these are the conditioning aspects that gives shape to a collectivity\'s verbal and visual language. These forms of languages delimit what we know or perceive about the world because they are codefying processes that transform phenomenons and manifestations themselves into concepts capable of being transmited one to another by their respective mechanisms of syntax. It is understood that every form of language created by humans is an analogy of the cosmos\' phenomenology.

Vi ville med denna uppsats undersöka om instant messaging matchar de kommunikationsbehov som IT-anställda har. För att ta reda på detta använde vi oss av ett kvalitativt angreppssätt i form av intervjuer. Dessa intervjuer skapade även ytterligare kunskap vilken vi benämnt barriärer. En lista på IM-funktioner hämtades från Wikipedia och reviderades senare av oss. Kommunikationsbehoven identifierades under analysen av intervjuerna. Matchningen genererade en tabell som kan användas som karta över vilka IM-funktioner som tillgodoser några vanliga kommunikationsbehov som finns på datortäta arbetsplatser. Barriärerna är till för att visa vad som försvårar tillgodoseendet av behoven. Vidare erhöll vi även kunskap om att de av oss identifierade kommunikationsbehov som i dagsläget inte tillgodoses av IM inte heller behöver göra det. Vi kom också fram till att IM skulle kunna utvecklas till att vara en brygga mellan annan kommunicerande programvara och kollegor.
