Wardell, Emily K. "Graphic Content Warning; Personal and Political Traumas." VCU Scholars Compass, 2019. https://scholarscompass.vcu.edu/etd/5849.
Full textAbstract:
The written portion of this thesis work is meant to address and further investigate the visual work created using mediums of print and found video. This artistic research has been interested in examining varying associations with truth, recollection, and evidence. This includes the recollection of public histories and news-media narratives as well as my own history and trauma. Through this work my aim was to create a deconstruction and revolt against how associations are formed, and how to understand imagery as information. This thesis first discusses my relationship to appropriated imagery, then connects and examines it through the addition of poetic elements and events from my own lived experience.

Full textAbstract:
Within the current national atmosphere of accountability and high-stakes testing, many teachers are changing their instruction to return to more traditional strategies that emphasize rote memorization. As a result, classroom curriculum and student learning are narrowing. This study sought to explore the potential of graphic organizers as an instructional strategy to expand student content knowledge beyond rote memorization to include more organized, complex, meaningful learning.
For the purpose of this study, graphic organizers are described as visual displays of concepts, their component parts, and the relationships among their parts. This study was conducted over a six week period in a third grade classroom in a rural elementary school in Virginia. Ten focus students were identified for in-depth data collection on their learning process as recorded during science instruction.
Although existing research strongly supports graphic organizer effectiveness as an instructional strategy toward general student achievement, little is known about the type of learning they support or the process by which students' knowledge develops. Thus, this research utilized qualitative methodological strategies in order to investigate this process. Data collection methods included field notes, student artifacts, and participant interviews. Constant comparative methodology was employed to analyze data. The theoretical framework of constructivism, espousing that newly acquired information is connected to prior knowledge forming complex, organized networks of conceptual understanding, guided this qualitative study.
Findings resulted in emergent themes including student motivation, simplicity, efficiency, visual hierarchical organization, reconstructing knowledge, and cooperative socialization. Documentation of the learning process as opposed to a comparison of pre/post measurements clearly indicated that student thinking gradually became more complex and organized in nature. As students worked with graphic organizers, and participated in study activities, their knowledge moved from a form of listing facts to resemble more complex, interconnected networks.
Implications of this study for practice include appropriate instruction and practice for students with graphic organizers as a strategy and a tool, value as an assessment tool, and potential for use with complex classroom populations. Suggestions for future research are given for teacher training on how to use graphic organizers effectively, interdisciplinary use of graphic organizers within one context, potential benefit for struggling and diverse learners, a continuing focus on process as opposed to product, and an examination of the connection between graphic organizer activities and sorting.Ph.

Full textAbstract:
This comparative pre-test/post-test quantitative study investigated the effect of an instructional strategy using concept mapping as a graphic organizer on the quality of persuasive writing compositions produced by fourth grade elementary school students. Six fourth grade classes were assigned as intact groups to three conditions: concept mapping treatment, four square treatment, and control. Participants wrote a pre-test essay prior to treatment. Treatment consisted of an instructional unit collaboratively developed by the researcher and classroom teachers on persuasive writing. Instruction for the three treatment groups was the same except for type of graphic organizer used (Concept Map, Four Square, or none). Following treatment, a post-test on persuasive writing was administered in the form of an essay. The concept mapping treatment group used concept mapping as their graphic organizer, the four square treatment group used the four square method, and the control group used no graphic organizer.
Each of the pre- and post-test essays for both treatment and control groups were scored using rubrics created collaboratively by the researcher and participating teachers for Persuasive Content and for Engagement with Content. Only the concept mapping treatment group created concept maps during the post-test. Therefore, only the concept mapping treatment groups’ essays received a score for Sophistication of the Concept Map.
One-way Analysis of Variance showed a significant mean difference in Persuasive Content and Engagement with Content between the three treatment groups. Concept Mapping had the highest mean scores on each, followed by Four Square and then the control. Pearson’s product-moment correlation showed a moderate positive correlation between Sophistication of Concept Map and both Persuasive Content and Engagement with Content. Positive correlations were also found between prior KCCT scores and persuasive writing scores and prior writing portfolio scores and persuasive writing scores. No significant correlation was found between gender and persuasive writing scores or race/ethnicity and persuasive writing scores.
The results of this study indicate that Concept Mapping improves Persuasive Content and Engagement with Content when used as a graphic organizer in the writing of persuasive essays.

yesAs Leeds Metropolitan is a university of festivals and partnerships, the library was given the opportunity this year to host a festival to promote the library and all its services to the university. The library festival was a week of events and activities to promote the library and its space in new ways. It was a good way to remind staff and students of the value of libraries, not only as places to learn but also as places to enhance our leisure and working lives ... we chose to promote the database `Land of Lost Content¿. This was because graphic design and art students are based at our campus and we also thought this database would attract a wide range of students who might otherwise think that electronic databases contain little of interest for them. Our promotion has been so successful in many ways that we would like to share our experience with other librarians.

Full textAbstract:
This study explored the opinions of teachers regarding use and effectiveness in the use of graphic organizers in their classroom instruction. Data collection and analyses sought to determine if participating teachers used graphic organizers in their classrooms and how effective teachers perceived graphic organizers to be in the areas of English/language arts, social studies, science, and math.
A descriptive statistical study was conducted using a survey emailed nationwide. Quantitative methods of data collection, including a questionnaire, were used to gauge teachers' attitudes and uses of graphic organizers in their classrooms. The majority of teachers surveyed indicated they were aware of graphic organizer use and effectiveness in the classroom. Future research topics and recommendations were summarized regarding the use of graphic organizers by teachers in the high school content classrooms.

Full textAbstract:
By augmenting an existing static medium (a graphic organizer) with attributes such that learners were able to sort or rearrange information in multiple ways, two new types of “dynamic” graphic organizers were created. An experiment was performed to investigate the effectiveness of these dynamic graphic organizers as instructional tools. One-hundred-sixty-one students were recruited for participation in the study from a two-year community college and a four-year public university in the southeast United States. Participants were randomly assigned to one of three graphic organizer treatment groups: static, sortable, and shuffle-sortable. Response accuracy and response latency measurements for three types of mental tasks (factual, comparative, and inferential) were compared across the three treatment groups.
A multivariate analysis of variance showed no significant difference between the three graphic organizer types for response accuracy. A within-groups analysis of variance showed no significant differences in response accuracy between mental tasks within the static or sortable treatment groups. However, analysis of variance indicated that accuracy for inferential judgments was lower than that for factual judgments in the shuffle-sortable group. With respect to response latency, a multivariate analysis of variance revealed no significant difference between the three treatment groups. A within-groups analysis of variance showed significant differences in response latency between factual and inferential judgment-making for both the sortable and shuffle-sortable treatments. The sortable treatment had the most pronounced differences in latency between mental tasks, whereas no significant differences in response latency were observed within the static treatment.
Participants in the two dynamic treatments reported much higher percentages of affirmative responses to the question, “Did you think your graphic organizer was an effective instructional tool?” with 82.7% and 81.5% responding “yes” for the Sortable and Shuffle-sort groups, respectively, and only 60.0% responding “yes” for the Static group.
The graphic organizers in the study are known as adjunct displays and therefore each was associated with an accompanying text passage. Participants had the capability of viewing the accompanying text passage at will within the constraints of a five-minute graphic organizer study period. Analysis of variance revealed that participants in the shuffle-sortable group spent significantly less time viewing the text passage than participants in the static group, possibly because the overhead associated with the shuffle-sortable graphic organizer’s user interface controls consumed time or mental resources that would have otherwise been used to view the text.
The results of this study suggest that dynamic graphic organizers are equivalent to traditional static graphic organizers, at least for the educational subject matter used in this study (comparative text comprising 204 words describing six fictitious species of fish, their attributes, and the relationships between these attributes) for measures related to accuracy. Additionally, participants in the two dynamic graphic organizer treatments took advantage of the affordances offered by those treatments (88.5% of the Sortable group sorted, 75.9% of the Shuffle-sort group sorted, and 88.9% of the Shuffle-sort group shuffled). This study may benefit both instructional designers and educational researchers as new curricula are designed and new instructional tools are studied, respectively.

Full textAbstract:
The purpose of this study was to investigate the effects of using graphic organizers during prereading, reading, and postreading positions of the comprehension and retention of Chinese sixth-grade students who were identified as below-average or above-average readers. Chinese sixth graders from one school were first administered The Michigan Chinese Reading Test to identify reading level. Subjects were then assigned to one of the four treatment groups: traditional Chinese social studies method, graphic preorganizers, graphic organizers as a reading guide, and graphic post organizers.Two practice passages were first used to familiarize the subjects with how graphic organizers were utilized in instruction before reading on experimental passage. The dependent measure, 45 multiple-choice questions based on the experimental passage, was administered twice: the next day after the instructional sessions were concluded and again seven days later.The principal analysis to test the three null hypotheses was a 2 x 4 x 2 ANOVA with repeated measures on the last factor corresponding to the two administrations of the test. Two follow-up analyses of variance (ANOVAs) were used to test for differences in treatment condition sepa-rately for above-average readers and below-average readers, using the average of the immediate and the seven-day delayed tests. One Scheffe test was applied to find the location of significant differences among the four treatment conditions for above-average readers. Finally, four follow-up t-tests were used to test for differences in reading level at each of the four treatment levels.Three conclusions were drawn from the statistical analyses of the data: 1) graphic organizers had a significant effect on comprehension and retention only when above-average readers were required to process the organizers during reading; 2) graphic organizers did not produce significantly better comprehension and recall performance of below-average readers; and 3) the effect of graphic organizers was equal to that of the traditional Chinese social studies method in maintaining comprehension and recall for both above-average readers and below-average readers over a one-week delay.Department of Elementary Education

Full textAbstract:
The issue of the image of African countries in European media is an age-long one which has resurfaced in recent times. Eyebrows have been raised over the image of African countries in Europe and other Western Media which is always touted to be negative.The question about how the EU is reported in the African media has however been relegated to the background. This study therefore used content analysis to unearth how the EU and its member countries are reported in the African Media particularly in the Daily Graphic, a leading Daily Newspaper in Ghana in two separate years of 1998 and 2008 and whether what is reported reflects colonial ties between EU member countries and their former colonies in Africa. The study which used both quantitative and qualitative methods of research also sought to investigate the power relations between African media and their European counterpart, the sources of the stories were examined to find out whether they are stories written by European media or in-depth analysis of issues written by Ghanaian or African reporters. Special emphasis was placed on issues around trade and aid between Africa and the European Union which comes across as the key issues. The years 1998 and 2008 were selected because it has a ten year interval in which one can assess whether coverage of EU related issues in the paper has improved over the last ten years especially as the EU has grown in membership and scope, deepening its process of integration and acquiring new responsibilities in the world.Findings of the study indicated a strong tie between some EU member countries and their former colonies, (i.e United Kingdom and Ghana).The study also found out that The Daily Graphic simply borrows stories from EU sources and reproduce them with very little or no analysis, comments, or criticisms, of the issues raised that may have implications for the country or Africa’s growth in terms of aid and trade issues. This is a pointer to the fact that European media has been setting the agenda and the Daily Graphic simply follows.The study further revealed the unequal power relations between the EU and for that matter Africa which also reflects in media relations whereby as a result of poor salaries, logistical support and appropriate technology, newspapers in Africa, such as the Daily Graphic are unable to send reporters to the EU headquarters in Brussels to report issues from the African point of view and as such reproduce what has already been reported in the European media by European reporters and sent down through wire services.Again from the study, it is evident that the Daily Graphic does not report regularly on issues on EU- Africa trade and aid. In 1998, aid related issues involving the EU and Africa were only six percent while that of 2008 was 11 percent. Trade related issues involving the EU and Africa recorded nine percent in both years. Also reporters lack of interest in analysis of the issues in feature articles was reflected in 97 percent of news stories in 1998 as against three percent of feature articles in the same year while 2008 recorded a woefully two percent of feature articles as against a whopping 98 percent of news stories.One of the issues that emerged as a surprise was the fact that contrary to expectations, EU related stories not connected to Africa received more coverage than what connects Africa to Europe. This may be an indication that African media gate-keepers are not selecting stories based on the interest of the country or continent but rather still serving their colonial masters under a new colonial empire facilitated by the EU. Theories underpinning colonialism such as Edward Said’s Orientalism, modernization, media and society theories have helped to discuss some of the issues under focus.

Prediger, Maciel. "How does the store flyer design and content features influence consumer behavior?" Doctoral thesis, Universitat de Barcelona, 2019. http://hdl.handle.net/10803/667921.
Full textAbstract:
Store flyers have an extraordinary importance to marketing management and contribute to a retailer's performance (Ziliani and Ieva, 2015). They influence the intentions to visit a store, affect the purchase of advertised and unadvertised products (Burton et al., 1999), improve sales volume of store brand products (Gázquez-Abad and Martínez-López, 2016), and contribute to better selling margins and profits (Volle, 2001). Therefore, retailers and packaged-good manufacturers, who are willing to pay to have their brands featured, are increasingly using store flyers as the primary vehicle for advertising their assortments, promoting new products, and communicating price specials to consumers (Gázquez-Abad et al., 2014; Gijsbrechts et al., 2003). Using store flyers, retailers can directly communicate with consumers, and influence preferences and behaviors throughout the stages buying cycle, both at home and in store (Gázquez-Abad and Martínez-López, 2016; Mimouni Chaabane et al., 2010).
We offer herein an improved understanding of how the features of the store flyer design and content features influence the consumer’s perceived variety of the retailer’s assortment, as a dimension of its global image. We evaluated the effect of different store flyer design scenarios on the intentions to visit the store and buy (especially a store brand product) and how the perceived store image and variety of the retailer’s assortment can moderate such buying decisions. We also evaluated how different store flyer designs and content features are used by consumers in their heuristic decision-making process to visit the store and buy, according to the principle of energy efficiency. Our findings are relevant to both researchers, manufacturers, and retailers. Besides improving the efficiency of store flyers, the new findings will allow the development of environmentally friendly store flyers. This study is the first to delve into the influence of the store flyer design on consumers’ behavior after actually glancing through the store flyer. Although there are previous studies on store flyers that used experiments, most of them were based on econometric models at the aggregate level. This is the first study to combine a between-subjects design with a conjoint analysis.

Full textAbstract:
In graphic design, colours can be used to communicate a message and attract attention. In book design, colours convey the content, just like they communicate the product’s information in packaging design. The purpose of this study is to analyse how colours have been used on book covers to convey the content, within the topic of health. A quantitative content analysis was made on the book covers of the top 11 bestsellers in Sweden. The colour theory analysis is based on Shigenobu Kobayashi’s work in Colour image scale. The result found that neutral hue was the one that was most commonly used. Additionally, the analysis revealed some correlation between the book content and the colour combination on the book covers. For example, a book related to finding happiness had a colour combination that matches a casual and natural lifestyle. Although the analysis offered some insight within the subject of colour and book design, further studies are needed in order to understand the extent of how colours are being used towards communicating the content.

Simply rendering a publication or object in two-dimensional digital format is no longer sufficient throwing a challenge to the institution – how to preserve their identity and character. In a time when it is becoming easier and easier to self-publish into the digital realm; as witnessed by social content, the rise of the e-book and the decentralization of content, what elements concern specifically to museum catalogues in this space? This work presents a selection suggestions applicable specifically to museum catalogues so they can leverage the emerging technologies and go beyond the printed versions, without losing touch with the artist, the exhibition and the institution.

Dans le premier cas, on considère des fonctionnelles additives sur deux modèles d'arbres aléatoires: le modèle de Catalan sur les arbres binaires (où un arbre est choisi avec probabilité uniforme sur l'ensemble des arbres binaires complets ayant un nombre de nœuds donné) et les arbres simplement générés (et plus particulièrement les arbres de Galton-Watson conditionnés par leur nombre de nœuds).Les résultats asymptotiques reposent sur les limites d'échelle d'arbres de Galton-Watson conditionnés. En effet, lorsque la loi de reproduction est critique et de variance finie (ce qui est le cas des arbres binaires de Catalan), les arbres de Galton-Watson conditionnés à avoir un grand nombre de nœuds convergent vers l'arbre brownien continu qui est un arbre réel continu qui peut être codé par l'excursion brownienne normalisée. Par ailleurs, les arbres binaires sous le modèle de Catalan peuvent être construits comme des sous arbres de l'arbre brownien continu. Ce plongement permet d'obtenir des convergences presque-sûres de fonctionnelles. Plus généralement, lorsque la loi de reproduction est critique et appartient au domaine d'attraction d'une loi stable, les arbres de Galton-Watson conditionnés à avoir un grand nombre de nœuds convergent vers des arbres de Lévy stables, ce qui permet d'obtenir le comportement asymptotique des fonctionnelles additives pour certains arbres simplement générés. Dans le second cas, on s'intéresse à la convergence de la fonction de répartition empirique des degrés ainsi qu'aux densités d'homomorphismes de suites de graphes finis, simples et denses. Une suite de graphes finis, simples, denses converge si la suite réelle des densités d'homomorphismes associées converge pour tout graphe fini simple. La limite d'une telle suite de graphes peut être décrite par une fonction symétrique mesurable appelée graphon. Etant donné un graphon, on peut construire par échantillonnage, une suite de graphes qui converge vers ce graphon. Nous avons étudié le comportement asymptotique de la fonction de répartition empirique des degrés et de mesures aléatoires construites à partir des densités d'homomorphismes associées à cette suite particulière de graphes densesThe aim of this thesis is the study of approximations and rates of convergence for functionals of large dicsrete graphs towards their limits. We contemplate two cases of discrete graphs: trees (i.e. connected graphs without cycles) and dense simple finite graphs. In the first case, we consider additive functionals for two models of random trees: the Catalan model for binary trees (where a tree is chosen uniformly at random from the set of full binary trees with a given number of nodes) and the simply generated trees (and more particulary the Galton-Watson trees conditioned by their number of nodes).Asymptotic results are based on scaling limits of conditioned Galton-Watson trees. Indeed, when the offspring distribution is critical and with finite variance (that is the case of Catalan binary trees), the Galton-Watson trees conditioned to have a large number of nodes converge towards the Brownian continuum tree which is a real tree coded which can be coded by the normalized Brownian excursion. Furthermore, binary trees under the Catalan model can be built as sub-trees of the Brownian continuum tree. This embedding makes it possible to obtain almost sure convergences of functionals. More generally, when the offspring distribution is critical and belongs to the domain of attraction of a stable distribution, the Galton-Watson trees conditioned to have a large number of nodes converge to stable Levy trees giving the asymptotic behaviour of additive functionals for some simply generated trees. In the second case, we are interested in the convergence of the empirical cumulative distribution of degrees and the homomorphism densities of sequences of dense simple finite graphs. A sequence of dense simple finite graphs converges if the real sequence of associated homomorphism densities converges for all simple finite graph. The limit of such a sequence of dense graphs can be described as a symmetric measurable function called graphon.Given a graphon, we can construct by sampling, a sequence of graphs which converges towards this graphon. We have studied the asymptotic behaviour of the empirical cumulative distribution of degrees and random measures built from homomorphism densities associated to this special sequence of dense graphs

Full textAbstract:
Simulation and game content includes the levels, models, textures, items, and other objects encountered and possessed by players during the game. In most modern video games and simulation software, the set of content shipped with the product is static and unchanging, or at best, randomized within a narrow set of parameters. However, ideally, if game content could be constantly and automatically renewed, players would remain engaged longer in the evolving stream of content. This dissertation introduces three novel technologies that together realize this ambition. (1) The first, NEAT Particles, is an evolutionary method to enable users to quickly and easily create complex particle effects through a simple interactive evolutionary computation (IEC) interface. That way, particle effects become an evolvable class of content, which is exploited in the remainder of the dissertation. In particular, (2) a new algorithm called content-generating NeuroEvolution of Augmenting Topologies (cgNEAT) is introduced that automatically generates graphical and game content while the game is played, based on the past preferences of the players. Through cgNEAT, the game platform on its own can generate novel content that is designed to satisfy its players. Finally, (3) the Galactic Arms Race (GAR) multiplayer online video game is constructed to demonstrate these techniques working on a real online gaming platform. In GAR, which was made available to the public and playable online, players pilot space ships and fight enemies to acquire unique particle system weapons that are automatically evolved by the cgNEAT algorithm. The resulting study shows that cgNEAT indeed enables players to discover a wide variety of appealing content that is not only novel, but also based on and extended from previous content that they preferred in the past. The implication is that with cgNEAT it is now possible to create applications that generate their own content to satisfy users, potentially significantly reducing the cost of content creation and considerably increasing entertainment value with a constant stream of evolving content.Ph.D.

Full textAbstract:
L’évolution du web, de ce qui était typiquement connu comme un moyen de communication à sens unique en mode conversationnel, a radicalement changé notre manière de traiter l’information. Des sites de médias sociaux tels que Flickr et Facebook, offrent des espaces d’échange et de diffusion de l’information. Une information de plus en plus riche, mais aussi personnelle, et qui s’organise, le plus souvent, autour d’événements de la vie réelle. Ainsi, un événement peut être perçu comme un ensemble de vues personnelles et locales, capturées par différents utilisateurs. Identifier ces différentes instances permettrait, dès lors, de reconstituer une vue globale de l’événement. Plus particulièrement, lier différentes instances d’un même événement profiterait à bon nombre d’applications tel que la recherche, la navigation ou encore le filtrage et la suggestion de contenus. L’objectif principal de cette thèse est l’identification du contenu multimédia, associé à un événement dans de grandes collections d’images. Une première contribution est une méthode de recherche d’événements basée sur le contenu visuel. La deuxième contribution est une approche scalable et distribuée pour la construction de graphes des K plus proches voisins. La troisième contribution est une méthode collaborative pour la sélection de contenu pertinent. Plus particulièrement, nous nous intéresserons aux problèmes de génération automatique de résumés d’événements et suggestion de contenus dans les médias sociauxThe ease of publishing content on social media sites brings to the Web an ever increasing amount of user generated content captured during, and associated with, real life events. Social media documents shared by users often reflect their personal experience of the event. Hence, an event can be seen as a set of personal and local views, recorded by different users. These event records are likely to exhibit similar facets of the event but also specific aspects. By linking different records of the same event occurrence we can enable rich search and browsing of social media events content. Specifically, linking all the occurrences of the same event would provide a general overview of the event. In this dissertation we present a content-based approach for leveraging the wealth of social media documents available on the Web for event identification and characterization. To match event occurrences in social media, we develop a new visual-based method for retrieving events in huge photocollections, typically in the context of User Generated Content. The main contributions of the thesis are the following : (1) a new visual-based method for retrieving events in photo collections, (2) a scalable and distributed framework for Nearest Neighbors Graph construction for high dimensional data, (3) a collaborative content-based filtering technique for selecting relevant social media documents for a given event

Full textAbstract:
Chatbots are computer programs with the capability to lead a conversation with a human user. When a chatbot is unable to match a user’s utterance to any predefined answer, it will use a fallback intent; a generic response that does not contribute to the conversation in any meaningful way. This report aims to investigate if a content-based recommender system could provide support to a chatbot agent in case of these fallback experiences. Content-based recommender systems use content to filter, prioritize and deliver relevant information to users. Their purpose is to search through a large amount of content and predict recommendations based on user requirements. The recommender system developed in this project consists of four components: a web spider, a Bag-of-words model, a graph database, and the GraphQL API. The anticipation was to capture web page articles and rank them with a numeric scoring to figure out which articles that make for the best recommendation concerning given subjects. The chatbot agent could then use these recommended articles to provide the user with value and help instead of a generic response. After the evaluation, it was found that the recommender system in principle fulfilled all requirements, but that the scoring algorithm used could achieve significant improvements in its recommendations if a more advanced algorithm would be implemented. The scoring algorithm used in this project is based on word count, which lacks taking the context of the dialogue between the user and the agent into consideration, among other things.

Full textAbstract:
The recent transformation of consumer graphics (CG) cards into powerful 3D rendering processors is due in large measure to the success of game developers in delivering mass market entertainment software that feature highly immersive and captivating virtual environments. Despite this success, 3D CG application development is becoming increasingly handicapped by the inability of traditional content creation methods to keep up with the demand for content. The term content is used here to refer to any data operated on by application code that is meant for viewing, including 3D models, textures, animation sequences and maps or other data-intensive descriptions of virtual environments. Traditionally, content has been handcrafted by humans. A serious problem facing the interactive graphics software development community is how to increase the rate at which content can be produced to keep up with the increasingly rapid pace at which software for interactive applications can now be developed. Research addressing this problem centers around procedural content creation systems. By moving away from purely human content creation toward systems in which humans play a substantially less time-intensive but no less creative part in the process, procedural content creation opens new doors. From a qualitative standpoint, these types of systems will not rely less on human intervention but rather more since they will depend heavily on direction from a human in order to synthesize the desired content. This research draws heavily from the entertainment software domain but the research is broadly relevant to 3D graphics applications in general.

Full textAbstract:
The present work introduces a set of solutions to extract graphs from enterprise data and facilitate the process of information search on these graphs. First of all we have defined a new graph model called the SPIDER-Graph, which models complex objects and permits to define heterogeneous graphs. Furthermore, we have developed a set of algorithms to extract the content of a database from an enterprise and to represent it in this new model. This latter representation allows us to discover relations that exist in the data but are hidden due to their poor compatibility with the classical relational model. Moreover, in order to unify the representation of all the data of the enterprise, we have developed a second approach which extracts from unstructured data an enterprise's ontology containing the most important concepts and relations that can be found in a given enterprise. Having extracted the graphs from the relational databases and documents using the enterprise ontology, we propose an approach which allows the users to extract an interaction graph between a set of chosen enterprise objects. This approach is based on a set of relations patterns extracted from the graph and the enterprise ontology concepts and relations. Finally, information retrieval is facilitated using a new visual graph query language called GraphVQL, which allows users to query graphs by drawing a pattern visually for the query. This language covers different query types from the simple selection and aggregation queries to social network analysis queries.

noThe results from previous experiments using structured musical stimuli to communicate coordinate locations within a graphical grid, navigation of an auditory cursor and simple shapes are used as a basis for further exploratory research to communicate diagrams. An experimental framework program (called AudioGraph) provided a platform for investigating musical information processing for blind users. Under this platform, simple arrangements of shapes (forming diagrams) were communicated to users using structured musical stimuli. Meaningfully arranged graphical shapes (at least for the visual sense) were communicated in the absence, and in the presence of a particular perceptual context or different perceptual contexts. The results indicated that perceptual context played an important role in the interpretation of the structured musical stimuli that communicated simple diagrams. The paper concludes with a discussion on the implications of the results, the role of context and the use of structured musical stimuli to communicate graphical information to visually impaired users.

Innovative technologies and their ability to grow rapidly are known to be a great source of controversy and paranoid reactions amongst people. The aim of this research is to examine the acceptance and perception of the technology of digital supermodels and influencers. This will be done in the global market of end-users where this technology has proliferated or has the potential to emerge. Digital supermodels and influencers were regarded specifically in a marketing context for this research, since the whole essence of their existence is for marketing purposes, and was approached as a new innovative technology. The research was divided into two parts, first was about conducting a questionnaire to analyse people’s acceptance of the technology, more specifically to examine the possible change in their purchasing behaviour. The purpose of the second part of given research was to examine people’s reactions and perception towards this technology through a content analysis of Instagram comments for the Instagram accounts of digital supermodels and influencers. The addressed innovative technology of digital influencers and supermodels is mostly perceived positively or neutrally. The significant amount of neutral positions in both parts of given research states the presence of confusion and the need for answers rather than lack of interest, which is to be addressed by the creators and users of digital avatars in marketing in the fashion industry.

Full textAbstract:
"Similarity is a central cognitive mechanism for humans which enables a broad range of perceptual and abstraction processes, including recognizing and categorizing objects, drawing parallelism, and predicting outcomes. It has been studied computationally through models designed to replicate human judgment. The work presented in this dissertation leverages general purpose semantic networks to derive similarity measures in a problem-independent manner. We model both general and relational similarity using connectivity between concepts within semantic networks. Our first contribution is to model general similarity using concept connectivity, which we use to partition vocabularies into topics without the need of document corpora. We apply this model to derive topics from unstructured dialog, specifically enabling an early literacy primer application to support parents in having better conversations with their young children, as they are using the primer together. Second, we model relational similarity in proportional analogies. To do so, we derive relational parallelism by searching in semantic networks for similar path pairs that connect either side of this analogy statement. We then derive human readable explanations from the resulting similar path pair. We show that our model can answer broad-vocabulary analogy questions designed for human test takers with high confidence. The third contribution is to enable symbolic plan repair in robot planning through object substitution. When a failure occurs due to unforeseen changes in the environment, such as missing objects, we enable the planning domain to be extended with a number of alternative objects such that the plan can be repaired and execution to continue. To evaluate this type of similarity, we use both general and relational similarity. We demonstrate that the task context is essential in establishing which objects are interchangeable."

The developed algorithms can be used to apply extracted properties to other drawings automatically; transfer a selected style; categorise images based upon perceived style; build 3D models using style features from concept artwork; and other style-based actions that change our perception of an object without changing our ability to recognise it. The research in this thesis aims to provide the style manipulation abilities that are missing from modern digital art creation pipelines.

Full textAbstract:
In this thesis visual search experiments are devised to explore the feasibility of an eye gaze driven search mechanism. The thesis first explores gaze behaviour on images possessing different levels of saliency. Eye behaviour was predominantly attracted by salient locations, but appears to also require frequent reference to non-salient background regions which indicated that information from scan paths might prove useful for image search. The thesis then specifically investigates the benefits of eye tracking as an image retrieval interface in terms of speed relative to selection by mouse, and in terms of the efficiency of eye tracking mechanisms in the task of retrieving target images. Results are analysed using ANOVA and significant findings are discussed. Results show that eye selection was faster than a computer mouse and experience gained during visual tasks carried out using a mouse would benefit users if they were subsequently transferred to an eye tracking system. Results on the image retrieval experiments show that users are able to navigate to a target image within a database confirming the feasibility of an eye gaze driven search mechanism. Additional histogram analysis of the fixations, saccades and pupil diameters in the human eye movement data revealed a new method of extracting intentions from gaze behaviour for image search, of which the user was not aware and promises even quicker search performances. The research has two implications for Content Based Image Retrieval: (i) improvements in query formulation for visual search and (ii) new methods for visual search using attentional weighting. Futhermore it was demonstrated that users are able to find target images at sufficient speeds indicating that pre-attentive activity is playing a role in visual search. A current review of eye tracking technology, current applications, visual perception research, and models of visual attention is discussed. A review of the potential of the technology for commercial exploitation is also presented.

Full textAbstract:
This study explored 14 to 15 year old pupils' graphical understanding and their teachers' pedagogical content knowledge. A diagnostic instrument was developed from the research literature to suit the UK National Curriculum, and was administered to 425 pupils. The problems were deliberately posed in such a way as to encourage relevant errors and misconceptions to surface. The test was 'scaled' using Rasch methodology and the result was a hierarchy of responses, each level of which was described as a characteristic performance including key misconceptions. Results showed that pupils were able to solve tasks involving both reading and interpretation of graphs from an early level. The hierarchy was generally consistent with previous literature. The errors were validated apart from one which is believed to be a new version of the so called 'interval-point' confusion. The instrument was also further developed to function as a questionnaire for assessing teachers' Pedagogical Content Knowledge (PCK). Teachers' estimation of the difficulty of the items, their proposed learning sequences and their awareness of errors and misconceptions were examined. Furthermore, teachers' perceptions of what is difficult were correlated with the children's actual difficulty estimates. Results showed that these teachers' estimation of what is difficult seemed to be partly structured by the curriculum sequence. Some of the teachers overestimated the difficulty of some tasks involving global interpretation and underestimated the difficulty of those which entailed pointwise reading or algebraic manipulation. Also, their knowledge was highly sensitive to the method adopted to collect the data. The teachers' mis-estimation of (relative) difficulties could be explained by one of two reasons: sometimes teachers apparently misunderstood the actual question themselves, and so underestimated the difficulty of the item. At other times, teachers overestimated the difficulty because they did not realise that children could answer the question without a sophisticated understanding of some concepts. Pupils' and teachers' responses were confirmed and enriched through group interviews and semi-structured interviews respectively.

Full textAbstract:
This thesis investigates new clustering paradigms and algorithms based on the principle of the shared nearest-neighbors (SNN. As most other graph-based clustering approaches, SNN methods are actually well suited to overcome data complexity, heterogeneity and high-dimensionality.The first contribution of the thesis is to revisit existing shared neighbors methods in two points. We first introduce a new SNN formalism based on the theory of a contrario decision. This allows us to derive more reliable connectivity scores of candidate clusters and a more intuitive interpretation of locally optimum neighborhoods. We also propose a new factorization algorithm for speeding-up the intensive computation of the required sharedneighbors matrices.The second contribution of the thesis is a generalization of the SNN clustering approach to the multi-source case. Whereas SNN methods appear to be ideally suited to sets of heterogeneous information sources, this multi-source problem was surprisingly not addressed in the literature beforehand. The main originality of our approach is that we introduce an information source selection step in the computation of candidate cluster scores. As shown in the experiments, this source selection step makes our approach widely robust to the presence of locally outlier sources. This new method is applied to a wide range of problems including multimodal structuring of image collections and subspace-based clustering based on random projections. The third contribution of the thesis is an attempt to extend SNN methods to the context of bipartite k-nn graphs. We introduce new SNN relevance measures revisited for this asymmetric context and show that they can be used to select locally optimal bi-partite clusters. Accordingly, we propose a new bipartite SNN clustering algorithm that is applied to visual object's discovery based on a randomly precomputed matching graph. Experiments show that this new method outperformed state-of-the-art object mining results on OxfordBuilding dataset. Based on the discovered objects, we also introduce a new visual search paradigm, i.e. object-based visual query suggestion.

This dissertation describes the design and evaluation of the Fast, Flexible Forwarding system (F3), a distributed system for disseminating information to networked subscribers. It examines existing subscription approaches, proposes F3 as an alternative to these approaches, and presents results from comparisons of F3 and other subscription approaches. Existing subscription approaches examined in the dissertation fall into three categories: unicast, single-identifier multicast, and content-based multicast systems. Careful examination of these approaches suggests that none is able to support complex subscription requests from large numbers of subscribers at high data rates. F3, the systems proposed as an alternative, shares many features with other multicast systems. Like many multicast systems, for example, F3 uses an overlay network of routers to distribute messages to subscribers. F3 differs from other systems, however, in its use of preprocessors to analyze messages before routing begins. Preprocessors carry out analyses of the relationships between subscription topics, and store the results in special content graph data-structures. Preprocessors share the results of their analyses by distributing content graphs to routers in the F3 network. Using content graphs, F3 routers can determine the relationships between subscriptions and notifications more efficiently than in previous approaches. Four studies compared performance of F3 and competing subscription systems. In the four studies, subscription systems handled such tasks as disseminating baseball scores, distributing traffic alerts, and disseminating generic subscriptions formatted as attribute-value pairs.
(cont.) The four studies examined system performance in both simulated network environments and on a working router. Performance characteristics examined in the studies included size of forwarding tables and processing speeds at routers. Results from these experiments showed that F3 does not overproduce messages, as do unicast systems. F3 also outperformed single-identifier multicast systems in such areas as message production, table size, and subscription overhead. The most significant finding of the studies, however, was that F3 processing speed surpassed the speed of a state-of-the-art content-based system by orders of magnitude in scenarios with large numbers of subscribers. Overall, these results suggest that F3 is a promising development in the area of Internet subscription systems.

This study investigated the comparison between captured and revealed Pedagogical Content Knowledge (PCK) about graphs of motion. The aim of the study was to explore PCK when captured in a written format and discussions (captured PCK) and compare it to the PCK that the same teachers revealed in practice (revealed PCK) when teaching the topic. Four Grade 10 Physical sciences teachers were purposively and conveniently selected as participants of the study. Their PCK was captured through Content Representations (CoRes) and interviews. The revealed PCK on the other hand was gathered through lesson observations. The Topic Specific Pedagogical Content Knowledge (TSPCK) model was used as the framework that guided the analysis of the two manifestations of PCK. The focus was on teachers’ competences in the TSPCK components namely; learners’ prior knowledge including misconceptions, curricular saliency, what is difficult to teach, representations including analogies, and conceptual teaching strategies. The results of this study indicated that teachers’ competences in the TSPCK components varied. This was evident in both the captured and the revealed PCK. Thus it suggested that a teacher’s level of competence in one component is not necessarily an indication of his or her competence in the other components that define PCK, and subsequently in his/her overall captured or revealed PCK. Furthermore, the study suggested that the level of competence in a component in the captured PCK is not necessarily an indication of the level of competence within that component that the teacher would reveal during lesson presentation. The level may be the same, slightly different (higher or lower) or even be drastically different in the lesson than suggested by the captured PCK. A concluding remark was then made that teachers’ captured PCK is not necessarily a true reflection of the PCK they reveal during lesson presentation and that different instruments must be used to reflect on and assess teachers’ PCK in a topic.Dissertation (MEd)--University of Pretoria, 2017.

Full textAbstract:
Computer screens are very small compared to the size of large information spaces that arise in many domains. The visualization of such datasets requires multiscale navigation capabilities, enabling users to switch between zoomed-in detailed views and zoomed-out contextual views of the data. Designing interfaces that allow users to quickly identify objects of interest, get detailed views of those objects, relate them and put them in a broader spatial context, raise challenging issues. Multi-scale interfaces have been the focus of much research effort over the last twenty years.There are several design approaches to address multiscale navigation issues. In this thesis, we review and categorize these approaches according to their level of content awareness. We identify two main approaches: content-driven, which optimizes interfaces for navigation in specific content; and content-agnostic, that applies to any type of data. We introduce the content-aware design approach, which dynamically adapts the interface to the content. The latter design approach can be used to design multiscale navigation techniques both in 2D or 3D spaces. We introduce Arealens and Pathlens, two content-aware fisheye lenses that dynamically adapt their shape to the underlying content to better preserve the visual aspect of objects of interest. We describe the techniques and their implementation, and report on a controlled experiment that evaluates the usability of Arealens compared to regular fisheye lenses, showing clear performance improvements with the new technique for a multiscale visual search task. We introduce a new distortion-oriented presentation library enabling the design of fisheye lenses featuring several foci of arbitrary shapes. Then, we introduce Gimlens, a multi-view detail-in-context visualization technique that enables users to navigate complex 3D models by drilling holes into their outer layers to reveal objects that are buried into the scene. Gimlens adapts to the geometry of objects of interest so as to better manage visual occlusion problems, selection mechanism and coordination of lenses.

Full textAbstract:
L'ambiente di questa tesi è quello del Delay and Disruption Tolerant Networks (DTN), un'architettura di rete di telecomunicazioni avente come obiettivo le comunicazioni tra nodi di reti dette “challenged”, le quali devono affrontare problemi come tempi di propagazione elevati, alto tasso di errore e periodi di perdita delle connessioni. Il Bunde layer, un nuovo livello inserito tra trasporto e applicazione nell’architettura ISO/OSI, ed il protocollo ad esso associato, il Bundle Protocol (BP), sono stati progettati per rendere possibili le comunicazioni in queste reti. A volte fra la ricezione e l’invio può trascorrere un lungo periodo di tempo, a causa della indisponibilità del collegamento successivo; in questo periodo il bundle resta memorizzato in un database locale. Esistono varie implementazioni dell'architettura DTN come DTN2, implementazione di riferimento, e ION (Interplanetary Overlay Network), sviluppata da NASA JPL, per utilizzo in applicazioni spaziali; in esse i contatti tra i nodi sono deterministici, a differenza delle reti terrestri nelle quali i contatti sono generalmente opportunistici (non noti a priori). Per questo motivo all’interno di ION è presente un algoritmo di routing, detto CGR (Contact Graph Routing), progettato per operare in ambienti con connettività deterministica. È in fase di ricerca un algoritmo che opera in ambienti non deterministici, OCGR (Opportunistic Contact Graph Routing), che estende CGR.
L’obiettivo di questa tesi è quello di fornire una descrizione dettagliata del funzionamento di OCGR, partendo necessariamente da CGR sul quale è basato, eseguire dei test preliminari, richiesti da NASA JPL, ed analizzarne i risultati per verificare la possibilità di utilizzo e miglioramento dell’algoritmo. Sarà inoltre descritto l’ambiente DTN e i principali algoritmi di routing per ambienti opportunistici. Nella parte conclusiva sarà presentato il simulatore DTN “The ONE” e l’integrazione di CGR e OCGR al suo interno.

The aim of this research, part of a wider program called SPOFIC, is to investigate how the casting procedure affects the concentration of hydrogen and nitrogen gases in Compacted Graphite Iron used for the production of truck cylinder blocks. Hydris equipment was used for the Hydrogen measurements and the Optical Emission Spectroscopy and combustion analysis methods were used for the nitrogen measurements. The experiment was performed in one of the cooperating foundries. It was found that Hydrogen content is increased during pouring of the melt into the mold but nitrogen content does not seem to be effected by the process. In both cases the gas content never exceeded the solubility limit. The results are comparable with results from similar researches regarding Gray Cast Iron.SPOFIC

Full textAbstract:
This thesis describes the implementation and evaluation of a modular approach for generating 2D side-scroller game levels from a procedurally generated 3D world. Manually generating large amounts of game levels can take considerable amounts of time, and it maybe desirable to automate this process, using procedural content generation. The problem with using procedural content generation is that it is hard to generate coherent game levels. We implement a modular pipeline which, given a set of heightmaps, generates a 3Dworld. From this world, 2D game levels are generated by pathing and extracting terrain features which influence the content in the game levels. The resulting 2D game levels will, using our approach, have a coherent and logical look. The game levels themselves do not contain any interesting gameplay. Instead they rely on a game level designer to add gameplay elements. The resulting modular implementation is considered a success, it proves that it is possible to generate 2D game levels from a procedurally generated 3Dworld, using the features of that world.
