Families migrate to improve their outcomes, however the process is very disruptive. My research asks and answers the question can scaffolding communication through technology mitigate the disruption caused to families by migration, and if so, how? In my work I have explored two forms of disruptive family migration—parental migration (where parents and children live in separate countries) and refugee resettlement (resulting from forced migration). In both forms, families are embedded in support networks of individuals they rely on to minimize vulnerabilities faced post-migration and to rebuild a stable family structure. My empirical results revealed barriers (distance, language, literacy and so forth) that render the communication between families and their support network less than effective. Through participatory approaches, I then design and evaluate separately, two systems to mitigate the barriers and improve communication in the various support networks. The end contributions of my work include: i) contributing a nascent agenda on migration for Human-Computer Interaction (HCI) and related fields through providing an increased understanding of the challenges that limit the livelihoods of migration-separated and refugee families; ii) demonstrating two communication scaffolding systems for transient use by migrants to mitigate communication barriers--- time and distance on one hand (to support transnational home-school communication) and language and literacy on the other (through mediated human-in-the-loop voice translations for everyday interactions with refugees); iii) putting forth a reflection on methods to guide others seeking to work with similar groups and establishing the notion of designing for transient use in the development of systems to scaffold communication.

The purpose of this study was (1) to examine rural residents’ perceived social support from Internet use for communication and (2) to understand the meanings associated with rural Internet users’ social media use, particularly with respect to mediating diverse social ties and exchanging different types of social support. To assess how Internet use affects rural residents’ sense of social support, this study investigated dynamic relationships between online communication and perceived social support by looking at interaction effects relative to extroversion, size of social networks, broadband use, and length of time using the Internet. To explore how social media are situated in a rural area, the present study investigated how rural residents use social network sites (SNSs) to maintain social contacts and exchange social support with members of their networks. / text

The purpose of this study was to explore how instructors of online courses accommodate and make provisions for culturally diverse learners in an online community of inquiry. Ten instructors from two Alberta higher education institutions participated in two phases of research. To explore this phenomenon in the CoI model, intercultural competency indicators were created to test how they could develop and expand teaching and social presence in a cross-cultural environment. In the first phase, analysis of the open-ended survey questionnaire (AMEQ) revealed that in the absence of any cross-cultural design, instructors use facilitation and open communication strategies to foster learning and prevent conflict. The second phase, informed by the first phase, involved augmenting the original 34-item CoI survey instrument. Additional roles that relate to instructor cross-cultural efficacy were incorporated into both teaching presence and social presence elements in the CoI survey instrument. The revised 37-item CoI survey instrument was then administered to the same respondents for face validity. Findings revealed that the incorporated cultural indicators correlated highly with the teaching and social indicators, indicating their usefulness to measure multicultural efficacy in the CoI model. / 2012-April

Computer-mediated environments such as social media create new social climates that impact communication interactions in un-mediated environments. This study examined social variables during conversations on Twitter through a qualitative document analysis that coded messages into affective, interactive or cohesive categories. Perceived social presence, participant satisfaction, and relationships between social presence and satisfaction among Twitter users during streaming conversations were examined through an online questionnaire that was created using qualtrics.com and made available to respondents over a one-week period. The researcher concluded that most social variables in the Twitter conversations of this study fall into the interactive social presence category. In addition, each category of responses functions in a different way to foster social presence. Two groups of survey respondents agreed with 10 out of 21 and 13 out of 21 statements about social presence and 10 out of 13 and 12 out of 13 statements about satisfaction. Findings indicated that positive and negative relationships exist between social presence and satisfaction. Both conversations in this study appeared to be successful. Therefore, agricultural communicators should feel comfortable using CMC more frequently to circulate agricultural information among populations across the globe. It was recommended that further research be conducted to examine social presence among new topics, populations, and other forms of CMC.

Empirical evidence suggests that individuals can hold different interpretations of a technology. In this research, I explore the question of where these different interpretations come from. What influences an individual s interpretation of a technology? And what is the nature of these interpretations? I explore these questions through studies of computer-mediated messaging systems, including instant messaging, photo-enhanced instant messaging, multimedia messaging (cameraphones), and mobile messaging (BlackBerries). In this research, I draw from philosophical hermeneutics, a domain of study examining the nature of interpretation, and present a technological hermeneutic, a descriptive theory of how individuals interpret technology how they come to understand the meaning of the technology in their own lives. This theory offers insight into the myriad resources individuals draw from when constructing an interpretation of technology, including their own experiences with related technologies as well as their interactions with others use and understanding of the technology. This theory also offers insight into the nature of the interpretive process. Interpretations are dynamic and evolving; individuals continually draw from new experiences, reengaging and reinterpreting technology. Interpretations are also hybrid and synthesized; individuals draw from multiple resources in an active process of interpretive bricolage.

O fenômeno do estrangeiro se apresenta na CMC em língua italiana como uma relação ao mesmo tempo de proximidade e distância, além de algumas barreiras para o desenvolvimento de uma sociabilidade entre italianos e estrangeiros. Na aproximação feita ao fenômeno do estrangeiro, em um dos sistemas mais usados na CMC, o webchat, verificou-se que apesar da possibilidade técnica de se construírem e de se utilizarem diversas identidades nos sistemas de CMC analisados, a identidade nacional se destaca na interação entre italianos e estrangeiros, acompanhada muitas vezes de hostilidades ou de um discurso retórico em relação aos imigrantes na Itália. / With the development of Computer-Mediated Communication (CMC), new forms of social interaction became possible and, despite of the fact that they are responsible for the creation of social groups in the cyberspace, we can also find some forms of exclusion. The “stranger phenomenon” presents itself, in the CMC that uses Italian language, as a relation, at the same time, of proximity and of distance, and also as barriers against the development of a sociability between strangers and Italians. By approaching the “stranger phenomenon”, through one of the most used CMC, the webchat, we could verify that, despite of technical possibility of constructing and of using multiple identities, national identity stands out in interrelation between Italians and strangers, bringing with it hostility or rethorical speeches related to immigrants in Italy.

Cette thèse concerne l’analyse automatique des SMS et l'extraction des informations qui y sont contenues. Le point de départ de notre recherche est le constat que la plupart des messages courts, observés dans le corpus alpes4science, présentent des différences en comparaison avec le langage standard. Les différences sont mises en évidence, d’une part, par la morphologie particulière des mots et, d’autre part, par les règles de syntaxe et de grammaire qui ne sont pas respectées lorsque l’émetteur considère que cela ne nuit pas à l’intelligibilité du message. À cause des écarts par rapport à la langue standard, le traitement et l'analyse des messages bruités est toujours un défi pour les tâches du TAL. Par conséquent, réduire les écarts est un défi fondamental que nous surmontons en utilisant l’approche de la normalisation pour la conception d’outils en traitement automatique des SMS.Nous proposons un modèle de normalisation en deux étapes, fondé sur une approche symbolique et statistique. La première étape vise à produire une représentation intermédiaire du message SMS par l’application de grammaires locales, tandis que la deuxième utilise un système de traduction automatique à base de règles pour convertir la représentation intermédiaire vers une forme standard. Le résultat produit par ce modèle a été évalué, par la suite, pour la reconnaissance d'entités nommées au travers d'une série de tests appliqués à l'aide de trois autres systèmes. Les résultats obtenus ont montré que les performances de ces systèmes de reconnaissance d'entités nommées présentent des améliorations significatives lorsqu’ils sont appliqués sur les SMS automatiquement normalisés en comparaison avec le corpus brut et manuellement transcrit.Mots-clés : communication médiée par ordinateur, langage SMS, normalisation des SMS, extraction d’informations / This thesis focuses on SMS language and information extraction from the point of view of natural language processing. The starting point of our study is the observation of the differences that most short messages have, using the alpes4science corpora, in comparison with the standard language. The differences are highlighted by the particular morphology of words and by the syntactic and grammar rules that are not respected when the issuer considers that it would not impair the intelligibility of the message.Because of the deviations from the standard language, processing and analyzing noisy messages is still a challenge for any NLP task. Therefore, reducing the gaps is a fundamental step to overcome when designing approaches for automatic SMS processing.We propose a two-step normalization model based on a symbolic and statistical approach. The first step aims to produce an intermediate representation of the SMS by applying local grammars. The second step uses a rule-based machine translation system to convert the intermediate representation to a standard form. The obtained result from this model was evaluated, afterwards, for named entities recognition through a series of tests applied thanks to three other systems. The results have shown that these performances of named entity recognition systems are significantly improved when applied to automatically normalized SMS in comparison with raw and manually normalized corpora.Keywords: computer-mediated communication, SMS language, SMS normalization

Advances in technology over the last few decades have led to significant changes in the way we communicate. Technological innovation has been one of the reasons for the development of computer-mediated communication (CMC), which has had far-reaching implications in the private and professional lives of many people. Instant messaging (IM), which is one form of computer-mediated communication, has significantly gained popularity over the years and many scholars have examined its influence in areas including business and academics. Initially developed to enhance communication between users who understood the same language, some IM clients including Wechat (www.wechat.com), QQ International (www.imqq.com), and Skype Translator (www.skype.com) have integrated a built-in translation application that facilitates communication among users that speak different languages. The current research project explores the relationship between machine translation, IM, and foreign language (FL) learning. In particular, it investigates whether machine-translated IM could improve the willingness to communicate (WTC) of beginner FL learners and whether the IM translation tool offers learners opportunities to communicate (OTC) in the FL. To answer these questions, China-based beginner FL learners were recruited and paired with native and near-native English speakers based in Canada. China-based participants completed two questionnaires and also exchanged (machine-translated) IM on selected topics with Canada-based participants for a period of ten weeks. Some China-based participants communicated with the help of the IM translation tool, while the others communicated without the tool. After analyzing the data gathered during the study, we found that WTC increased more for participants with the IM translation tool than for participants without the IM translation tool. Our analysis also indicated that the IM translation tool offered participants OTC in English. This was illustrated in various conversation aspects including number of words and turns exchanged, synchronous exchanges, ownership, conversation enhancement, topics discussed, tasks undertaken, and requests for paraphrase, repetition and explanation. In the discussion of the implications of our findings, we outline how the research project reinforced our understanding of the concept of WTC in a technology driven FL learning environment. We also discuss the implications of our findings for machine translation (MT), FL, and translation studies. Our discussion focuses on the debate on the tools to use and content to teach in the translator and FL training environments as well as various concepts in translation studies including MT quality, writing for MT, fit-for-purpose MT, collaboration and MT post-editing. This project enables us to test the applicability of MT in a different context using a novel group of users. The project therefore contributes to ongoing research on the relationship between CMC (specifically IM), MT, and FL learning, as well as to our knowledge of applications and perceptions of MT.

The language used in Massively Multiplayer Online Role Playing Games (or MMORPGs) is a form of computer-mediate communication. It consists of elements from both written and spoken language, but it is a highly abbreviated and innovative form of written language. This study focuses on the English language used in a MMORPG called Warhammer Online. The aim of this study is to identify abbreviations, interpret their meanings and to analyze the word formation processes and semantic changes that are involved in new words. The method used in this study is a qualitative case study of the English language in a MMORPG from a synchronic point of view. The secondary sources used in this study include previous works on morphology and semantics. The material used is based on logs acquired from the game Warhammer Online as a subscribed player. The results presented in this study show new and unique words created by players in Warhammer Online, along with other semantic changes that have taken place. It is concluded that the English written language has not seen such a major change in its entirety before, within one community.
