The AEC industry has long been in need of effective modes of information exchange and knowledge sharing, but their practice in the industry is still far from satisfactory. In order to maintain their competence in a highly competitive environment and a globalized market, many organizations in the AEC industry have aimed at a move towards the development of learning organizations. Knowledge management has been seen as an effective way to have every member of an organization engaged in learning at all levels. At the very centre of knowledge management and learning is knowledge sharing through effective communication. Unfortunately, however, there is a big gap in the AEC industry between existing practice and the ideal in this area. In order to effectively coordinate information and knowledge flow in the AEC industry, this present research has developed a framework for an information system – a Construction Information and Knowledge Protocol/Portal (CIKP) which integrates within it a publish/subscribe system, Semantic Web technology, and Social Web concepts. Publish/subscribe is an appropriate many-to-many, people-to-people communication paradigm for handling a highly fragmented industry such as construction. In order to enrich the expressiveness of publications and subscriptions, Semantic Web technology has been incorporated into this system through the development of ontologies as a formal and interoperable form of knowledge representation. This research first involved the development of a domain-level ontology (AR-Onto) to encapsulate knowledge about actors, roles, and their attributes in the AEC industry. AR-Onto was then extended and tailored to create an application-level ontology (CIKP-Onto) which has been used to support the semantics in the CIKP framework. Social Web concepts have been introduced to enrich the description of publications and subscriptions. Our aim has been to break down linear communication through social involvement and encourage a culture of sharing, and in the end, the CIKP framework has been developed to specify desired services in communicating information and knowledge, applicable technical approaches, and more importantly, the functions required to satisfy the needs of a variety of service scenarios.

The History of the Book in Canada / Histoire du livre et de l’imprimé au Canada and other national book history projects have been a catalyst for research into the local production of print and have highlighted the need for more study of the print trades in smaller centres. In Ontario during the nineteenth century independent weekly newspapers were printed in most villages, while larger towns boasted more than one print shop and often one or more booksellers and stationers. Bookbinders were active members of the book trades selling books and stationery, ruling paper, binding local pamphlets, periodicals, and books, and manufacturing blankbooks for a variety of purposes. Since much local printing was ephemeral in nature, the only evidence of its existence is found in the record books kept by printers and binders. Partial business records and other surviving artifacts of the Guelph Bookbindery, which operated from 1855 to 1978, are both a rich source of evidence of the day-to-day operations of the bookbindery and a key to the intersection of print trades in Guelph, Ontario, and the surrounding counties. This study uses local imprints, blankbooks, authors’ papers, newspapers, directories, maps, assessment records, photographs, museum artifacts, and oral history accounts to reconstruct a history of the bookbindery and its place in the print culture of nineteenth-century Guelph. It documents the transformation of a business selling books, stationery, and wallpaper into a commercial bindery, which along with local printers produced large numbers of pamphlets, ubiquitous then but increasingly rare today. It is a view into the microcosm of a dynamic community where print was a vital medium for communication reflecting the cultural, commercial, and entrepreneurial discourse in nineteenth-century Canadian society that reached far beyond its borders.

Right now you are reading a sentence. Earlier, you might have been looking at a realistic picture, such as a photograph, or an outline drawing in a set of instructions. If you are a programmer, you work with sentence-like structures, such as code, or a system diagram. These are all graphic representations. To varying degrees, the effectiveness of every graphic representation relies on its ability to convey the designer’s intended meaning and elicit the intended reaction from its audience. However, the design of graphic representations, even in technical domains such as visual programming language design or interactive information visualization, currently relies heavily on general principles based solely on practice, intuition, and informal measures of effectiveness from the applied art and craft of design (as opposed to scientific analysis or theory). There is an increasing demand for a scientific understanding of design and its evaluation from stakeholders (who seek evidence for effectiveness) and designers (who seek to advance their field). Because both the creation of graphic displays and their perception are literally embodied experiences, a model was developed with an embodiment orientation, specifically based on how graphics are perceptually and cognitively processed. In my research, I found that graphic representations are constituted of two properties, pictorial and symbolic information, that emerge through two interrelated aspects of perception. In sighted individuals, for example, every graphic representation makes use of biological capabilities to process visual sensation (i.e., light hitting the retina), which are processed in relation to culturally-learned capabilities (i.e., writing). I observed how graphic representations – such as pictures, diagrams, and sentences – are “naturally selected” (i.e., during different phases of design or problem solving). From these observations, I developed a model that distinguishes and predicts the effectiveness of pictures, diagrams, and sentences, in terms of how object relations and attributes are pictorially or symbolically represented, relative to the functional roles of those representations, contexts, and in some cases, individual perceptual-cognitive differences among perceivers. This model is a step toward a science of graphics that could lead to evaluation techniques for information systems, theories for inclusive design, and ergonomically designed software programming tools.

La présente recherche vise à explorer et à décrire l’accommodation des valeurs professionnelles au sein du système de valeurs culturelles par les bibliothécaires universitaires sénégalais. Elle répond aux questions de recherche suivantes : (1) Quel est le système de valeurs culturelles dominant chez les bibliothécaires universitaires sénégalais ? (2) Comment les bibliothécaires universitaires sénégalais priorisent-ils leurs valeurs professionnelles ? (3) Comment les bibliothécaires universitaires sénégalais accommodent-ils leurs valeurs professionnelles à leurs valeurs culturelles ?cette recherche confirme la théorie de la prédominance dans les sociétés africaines en général d’un système de valeurs s’inscrivant dans l’axe « Continuité – Dépassement de soi » du modèle théorique de Schwartz (2006, 1992). Dans ce système, les valeurs dominantes sont des valeurs de types universalisme, bienveillance, tradition, conformité et sécurité. Ces valeurs favorisent l’intégration de l’individu au groupe, la solidarité et la sécurité familiale et le refus des actions de nature à porter atteinte à l’harmonie du groupe. Au plan pratique, la recherche démontre la nécessité de renforcer la socialisation professionnelle en intégrant l’éthique et les valeurs dans la formation des bibliothécaires universitaires sénégalais. / A profession basically includes two components: scientific skills and professional values, which are the guidelines of professionals’ daily demeanor. The library profession is based on values like the preservation of humanity cultural heritage, a fair access to knowledge, intellectual freedom, confidentiality and the protection library users’ private lives, professional neutrality, tolerance etc. In Senegal as well as in the other African countries, libraries are, on the whole, legacies of colonialism. The values of library science were designed in a western perspective. This profession value system may sometimes conflict with the Senegalese librarians’ cultural value systems. However, very little is known on ways Senegalese professionals cope with these two value systems. This present research will describe and explore the interactive co-existence and adaptation of professional values within the cultural value system of Senegalese academic librarians. It seeks to answer the following research questions: (1) what is the Senegalese academic librarians’ dominant cultural value system? (2) How do Senegalese academic librarians prioritize their professional values? (3) How do Senegalese academic librarians adapt their professional values to cultural values? This exploratory and descriptive analysis combines a mixed methodology approach: Two types of data collecting methods have been used: a questionnaire based on interviews and on Schwartz’s Portrait Values Questionnaire (PVQ) (Schwartz, 2006) The findings highlight the fact that, on the cultural level, Senegalese academic librarians essentially emphasize, in the value system, the interests of the social group they belong to, the respect of social order and adoption of normative behavior in order to facilitate their relationships with the other group members. The values favor a strong integration of the individual into a group but do not encourage an action and thought autonomy which may destroy social harmony. On the professional level, they regard access to information, preservation and conservation of heritage and the denial of all sorts of discriminations as essential professional values. As professional values conflict with cultural norms, Senegalese academic librarians often seek a compromise, a balanced position to make decision which does not basically question their cultural values. When a compromise is impossible, the final decision is made in favour of cultural values. On the theoretical level, this research confirms the theory of a value system predominance rooted in Schwartz’ perspective of the “continuity/self-transcendence” (Schwartz, 2006, 1992). In his system, the dominant values are universalism, benevolence, tradition, conformity and security. These values favor the individual’s integration into a group, solidarity and family security and the refusal to undertake actions which may endanger group harmony. On the practical level, this research displays the necessity to reinforce professional socialization which includes ethics and values in the training of Senegalese academic librarians.

L’évolution technologique et l'accroissement de la population vieillissante sont deux tendances majeures de la dernière décennie. Durant cette période, la prolifération ubiquitaire de la téléphonie mobile a changé les habitudes de communication des gens. Le changement constant des appareils téléphoniques portatifs, l'augmentation des fonctions, la diversité iconographique, la variété des interfaces et la complexité de navigation exigent aujourd’hui non seulement plus de temps d'adaptation et d’apprentissage, mais représentent aussi un effort cognitif important. Les technologies d'information et de communication (TIC) sont devenues des outils incontournables de la vie moderne. Pour les personnes âgées, cet univers en perpétuelle mutation avec ces nouveaux appareils représente un obstacle à l’accès à l’information et contribue ainsi au gap générationnel. Le manque de référence et de soutien et les déficiences physiques ou cognitives, que certaines personnes développent en vieillissant, rendent l'usage de ce type d’objet souvent impossible. Pourtant, les produits intelligents plus accessibles, tant au niveau physique que cognitif sont une réelle nécessité au sein de notre société moderne permettant aux personnes âgées de vivre de manière plus autonome et « connectée ». Cette recherche a pour but d'exposer les défis d'usage des téléphones portables existants et d'identifier en particulier les problèmes d’usage que les personnes âgées manifestent. L’étude vise la tranche de population qui est peu habituée aux technologies de communications qui ne ciblent le plus souvent que les plus jeunes et les professionnels. C’est en regardant les habitudes d’usage, que la recherche qualitative nous permettra d’établir un profil des personnes âgées par rapport au TIC et de mieux comprendre les défis liés à la perception, compréhension et l’usage des interfaces de téléphones portables. / Technological progress and the growing aging population are two major trends of the last decade. The ubiquitous proliferation of mobile communication devices during this period has significantly altered people’s communication habits. The constantly changing mobile phones, their increasing features, the numerous icon designs, the variety of user interfaces and its complex navigation require nowadays not only more time for adaptation and learning but also a significant cognitive effort. Information technology and communication (ICT) have become essential tools of modern life. For seniors, this constantly mutating universe with its new digital devices makes information accessible to many thus contributing to a generational divide. The lack of reference and support and the physical or cognitive impairment that some people often develop while aging makes the use of such products very difficult. Both, a physically and cognitively accessible system becomes a real necessity in our modern society since it could help seniors live more autonomously and« connected ». This research aims to identify the challenges related to mobile phone use and reveal specific problems that older people encounter. The study focuses on the population that is little familiar with these devices especially since communication technologies seem aimed at the younger generations and professionnels. Through qualitative research seniors’ usage pattern will be studied allowing us not only to establish different user profiles with respect to ICT but also to better understand the challenges related to the perception, comprehension and manipulation of mobile phone user interfaces.

The first rule of writing is an important one: writers should not plagiarize; what they write should be their own. It is taken for granted. But who made the rule? Why? And how is it enforced? This dissertation traces the history of proprietary authorship from the earliest distinctions between imitation and misappropriation in the humanist schoolroom, through the first recorded uses in English of the Latin legal term plagiary (kidnapper) as a metaphor for literary misappropriation, to an inchoate conception of literary property among a coterie of writers in early modern England. It argues that the recognition of literary misappropriation emerged as a result of the instrumental reading habits of early humanist scholars and that the subsequent distinction between authors and plagiarists depended more upon the maturity of the writer than has been previously recognized. Accusations of plagiarism were a means of discrediting a rival, although in this capacity their import also depended largely upon one’s perspective. In the absence of established trade customs, writers had to subscribe to the proprieties of the institutions with which they were affiliated. They were deemed plagiarists only when their actions were found to be out of place. These proprieties not only informed early modern definitions of plagiarism; they also helped define the perimeters of proprietary authorship. Authors who wished to make a fair profit from labours in print had to conform to the regulations of the Stationer’s Company, just as authors who maintained a proprietary interest in their manuscripts had to draw upon legal rhetoric, such as plagiary, in the absence of a legally recognized notion of authorial property. With new information technologies expanding the boundaries of proprietary authorship everyday, the proprieties according to which these boundaries were first defined should help teachers and researchers not only better to understand the nature of Renaissance authorship but also to equip their students for the future.

This research examines situated behaviours and perceptions around textual navigation as it is practiced in situ by professionals working in various domains. In its investigation of interactions between human cognition and mediating artifacts, this research relies heavily on the resources of cognitive ethnography, including both observation and in-depth interviews with participants. Relevant contributions from the fields of information studies, book history, digital humanities, and human-computer interaction are presented to further elucidate the findings of this study. The findings reveal several emergent, interrelated navigational strategies, such as the use of annotations as navigational aids, reliance on automated interface actions, and the navigational value of interface metaphors. In further addressing the practice of textual navigation, this research also describes the creation of a prototype interface reflecting the study’s findings. This research proposes new ways of conceptualizing textual navigation and designing interfaces that support emergent textual interaction.

Doctor of Philosophy / Agronomy / Kevin Price / Stephen M. Welch / Plant phenotyping has been studied for decades for understanding the relationship between plant genotype, phenotype, and the surrounding environment. Improved accuracy and efficiency in plant phenotyping is a critical factor in expediting plant breeding and the selection process. In the past, plant phenotypic traits were extracted using invasive and destructive sampling methods and manual measurements, which were time-consuming, labor-intensive, and cost-inefficient. More importantly, the accuracy and consistency of manual methods can be highly variable. In recent years, however, photogrammetry and 3D modeling techniques have been introduced to extract plant phenotypic traits, but no cost-efficient methods using these two techniques have yet been developed for large-scale plant phenotyping studies. High-throughput 3D modeling techniques in plant biology and agriculture are still in the developmental stages, but it is believed that the temporal and spatial resolutions of these systems are well matched to many plant phenotyping needs. Such technology can be used to help rapid phenotypic trait extraction aid crop genotype selection, leading to improvements in crop yield. In this study, we introduce an automated high-throughput phenotyping pipeline using affordable imaging systems, image processing, and 3D reconstruction algorithms to build 2D mosaicked orthophotos and 3D plant models. Chamber-based and ground-level field implementations can be used to measure phenotypic traits such as leaf length, rosette area in 2D and 3D, plant nastic movement, and diurnal cycles. Our automated pipeline has cross-platform capabilities and a degree of instrument independence, making it suitable for various situations.
