Allusions explores the volatile nature of intimate relationships by revisiting and recovering my memory of dramatic experiences in my own intimate relationships then translating them into painted psychological scenes. These scenes are activated by symbolically charged objects and interrupted by openings or portals serving as points of entry or exit. The people involved are referred to by pieces of carefully chosen furniture situated in a space that has shifting perspectives and illogical planes, referencing the complexity of memory and the subjectivity of experience. Discordant color, texture, and layered information are used to heighten the drama of the moment. These painted panels and ceramic structures are a manifestation of my mental processing of interpersonal exchanges and remembered experiences through the development of a unique visual vocabulary in paint. / Includes bibliography. / Thesis (M.F.A.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

The literature contains conflicting ideas about the effectiveness of diagrams, and their constituent symbolism as teaching and learning tools. In addition, only limited research has been specifically conducted on the presentation and interpretation of arrow symbolism used in biology diagrams, let alone on the nature, source and remediation of student difficulties caused by arrows. On the basis of this limited research and 30 years of experience of teaching biology at secondary-level, the author suspected that students might have difficulties interpreting arrow symbolism in diagrams used as explanatory tools and decided to thoroughly investigate this issue. The hypothesis, 'Secondary-level students have difficulty with the use of arrow symbolism in biology diagrams' was formulated and the following broad research questions defined to address the hypothesis: 1. How much of a problem is arrow symbolism in diagrams? 2. How effectively is arrow symbolism used in diagrams to promote the communication of intended ideas? 3. To what extent does the design of arrow symbolism in diagrams influence students ' interpretation and difficulties? 4. How can the emerging empirical data and ideas from literature be combined to illustrate the process of interpretation of arrow symbolism? 5. What measures can be suggested for improving the presentation and interpretation of arrow symbolism in biology diagrams at secondary-level? To address Research question 1, a content analysis of all arrow symbolism in seven popular secondary-level biology textbooks was undertaken. This revealed a wide diversity of arrow styles, spatial organisations, purposes and meanings that could be confusing to students. These results suggested the need for an evaluation of the effectiveness of arrow symbolism (Research question 2). As there was no definitive set of guidelines available for specifically evaluating arrows, general guidelines from the literature on diagrams were used to develop a set of 10 criteria, to evaluate the syntactic, semantic and pragmatic dimensions of arrow symbolism, which were validated by selected educators, students and a graphic design expert. Application of the criteria (which constituted expert opinion) to the arrow symbolism used in 614 realistic, stylised and abstract diagram types, revealed a relatively high incidence (30%) of inappropriately presented arrow designs that could mislead students. To establish whether this problem could be the cause of student difficulties, and to thereby address Research question 3, a stylised and an abstract diagram were selected and evaluated according to the criteria. The results of the evaluation were compared to the responses given by 174 students to a range of written and interview probes and student modified diagrams. In this way, student performance was correlated with expert opinion. The results confirmed that students experience a wide range of difficulties (26 categories) when interpreting arrow symbolism, with some (12 categories) being attributable to inappropriately presented arrow symbolism and others (14 categories) to student-related processing skills and strategies at both surface- and deeper-levels of reasoning. To address question 4, the emerging empirical data from the evaluation and student studies was combined with a wide range of literature, to inform the development of a 3-level, non-tiered model of the process of interpretation of arrow symbolism in diagrams. As this model emphasised the importance of both arrow presentation in diagrams and arrow interpretation by students, it could be used as an effective explanatory tool as well as a predictive tool to identify sources of difficulty with the use of arrow symbolism. This model was, in turn, used to inform the compilation of a range of guidelines for improving the presentation and interpretation of arrow symbolism, and so target Research question 5. These, and other guidelines grounded in the data and relevant literature, were suggested for all role players, including students, educators, textbook writers, graphic artists and researchers, to use as remedial tools. Future research should focus on the implementation of these guidelines and studying their effectiveness for improving the presentation and interpretation of diagrams with arrow and other types of symbolism. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

One idea common in the computer industry today is that by the time a technological innovation reaches the mass market it is already obsolete. News of recent technological developments race quickly through the computer industry, creating large scale competition among various businesses for the dollars of both educational institutions and industries. In an effort to produce sophisticated and powerful software readily accessible to users whose area of expertise is not programming, software developers have increasingly turned toward the simplest form of language and concept representation--the icon. As icons become increasingly sophisticated and their function grows, so will their availability in various interfaces. The number of users who operate them will also increase. Advanced help systems and animation will assist in relieving some difficulties while creating others. In either case, icon recognizability will be a crucial factor for anyone (novice or expert) who will use them. The purpose of this study was to verify whether all users unfamiliar with a graphical user interface (GUI) system, specifically icons, will require assistance with 40' "W those icons that are unrecognizable in either form or function. Based on the results of this study, an icon recognizability does exist among different groups of computer users. This recognizability is based upon the experience of the users and not upon the type of software they may use most often.

Thesis (MA)--Stellenbosch University, 1999. / ENGLISH ABSTRACT: In this thesis an exploration is made into whether or not hieroglyphs reflect ideas of the ancient Egyptians themselves. By examining "living creature" hieroglyphs one may contemplate why the ancient Egyptian chose a particular manner of depiction. The manner of depiction can then be examined insofar as what ideas they may reflect. In this way study into other groups of signs such as those of the environment may be used to further illuminate the lives and our understanding of the ancient Egyptian(s). This thesis begins with an examination of both the problem inherent in such a task and an overview of some of the "processes" involved. By understanding that a reconstructed reality, that of the hieroglyph, reflects both real and perceived characteristics represented in glyphic form, one may seek out the mental impressions considered relevant to the people themselves. Next the role literacy played and still plays is discussed. This discussion includes a brief historical overview of both the history of decipherment and the "language" of the ancient Egyptians. The importance of "writing", artistic in nature in Egypt in regards to hieroglyphs, is then discussed as it relates to its use as symbol. Hieroglyphs are then discussed in their role as art, communication, and language emphasizing the multitudinous role(s) which they served. The importance is thus reiterated that hieroglyphs served as a communication of ideas to both the literate and the "illiterate" in at least a menial manner. After providing a "background" context of both the world and time of hieroglyphs and their subsequent "understanding" and interpretation, there is an analysis of the hieroglyphs for living creatures including the following Gardiner groupings: (1) mammals, (2) birds, (3) amphibians and reptiles, (4) fish, (5) invertebrates and lesser animals. The signs are examined in regards to their function and variations followed by some observations and comments related to the "structure" and perspective of the sign itself. Summary observations and comments are then made about each group. The thesis is then brought full circle by examining the implications of what hieroglyphs can tell us about the ancient Egyptians, via the perceptive and communicative role which they played. By understanding hieroglyphs as "fingerprints" of/from the mind of the people and subsequently their culture, this framework may provide a new mechanism into understanding the Egyptian via their own visualization and perceptive nature. A case is then proposed that this new "mechanism", if it is indeed considered feasible, can be applied to not only the physical world consisting of nature such as the environment, but also to groups which depict manmade objects. / AFRIKAANSE OPSOMMING: In hierdie tesis is die moontlikheid ondersoek dat hierogliewe iets van die ideewereld van die antieke Egiptenare reflekteer. In die bestudering van "lewende wese" hierogliewe kom vrae op soos waarom die antieke Egiptenare juis 'n spesifieke vorm van voorsteIIing verkies het. Die vorm van voorsteIIing kan dan bestudeer word vir die idees wat dit moontlik mag reflekteer. Ander groepe/velde van tekens, soos die van die breër omgewing, kan gebruik word om verdere lig te werp op die lewe van die antieke Egiptenaar(e) en ons verstaan daarvan. Die tesis begin met 'n bestudering van die inherente probleme in die aanpak van so 'n taak en 'n oorsig oor sommige van die "prosesse" daarby betrokke. By die verstaan van die hieroglief as 'n gekonstrueerde realiteit, wat weklike sowel as afgeleide eienskappe reflekteer, ontdek die ondersoeker daarvan iets van die persoonlike/kulturele indrukke wat deur hierdie groep mense as relevant ervaar is. In die volgende afdeling kom die rol van geletterdheid aan die beurt. Hierdie bespreking sluit 'n bondige historiese oorsig oor die geskiedenis van ontsyfering asook die taal van die Egiptenare in. Die belang van die "skryfkuns" en veral die kunsaard daarvan in die Egiptiese hierogliewe word vervolgens bespreek. Dit is veraI waar soos dit in verhouding staan met die gebruik daarvan as simbool. Die veelsydige rol(le) en belang van hierogliewe in die kuns, kommunikasie en taal word dan ondersoek en bespreek. Die klem word daarop gelê dat hierogliewe as die kommunikasie van idees aan beide die geletterde en "ongeletterde" dien. Nadat 'n agtergrondkonteks van die wereld en tyd van die hierogliewe en die daaruitvloeiende "verstaan" en interpretasie daarvan gegee is, word 'n analise van die "lewende wese" hierogliewe gedoen. Dit sluit die volgende groeperinge van Gardiner in: (1) soogdiere, (2) voels, (3) amfibiee en reptiele, (4) visse, (5) invertebrata en kleiner diere. Hierdie hierogliewe word ondersoek in terme van hulle funksie en variasies, gevolg deur waarnemings en opmerkings aangaande die "struktuur" en die perspektief van die teken. Opsommende observasies en enkele opmerkings oor elke groep volg daarna. Die tesis word afgerond met 'n ondersoek na die implikasies van wat ons kan wys word uit die hierogliewe aangaande die antieke Egiptenare, via die perspektiwiese en kommunikatiewe rol wat dit vervuI. Deur hierogliewe te verstaan as die "vingerafdrukke" van die begrip van hierdie mense kan hierdie raamwerk 'n nuwe meganisme in die verstaan van die Egiptenaar via die visualisasie en waarneembare aard daarvan, vorm. 'n Voorstel word gemaak dat hierdie nuwe "meganisme", indien dit uitvoerbaar is, toegepas kan word, nie net op die hierogliewe van die fisiese wereld bestaande uit die natuur en die omgewing nie, maar ook op hierogliewe wat mensgemaakte voorwerpe voorstel.

Thesis (DTh)--University of Stellenbosch, 1995. / ENGLISH ABSTRACT: A number of theories aimed at more effective ways of religious education have seen the light in recent years. They are all characterized by a holistic approach which emphasises the fact that we should try to utilise more than just the cognitive and verbal potential of man. This study does not merely accept this view but would also like to go further and look for practical means to implement these ideas. The central hypothesis of the study is that symbols and rituals are eminently suitable instruments if one opts for a holistic approach towards religious education. Various shifts which have recently occurred in modern society are highlighted in the study. These include a new outlook on life, new behavioural patterns, new ways of communication and new theories on communication. The complexity of our society is described because it has a major influence on the functioning of symbols and rituals. Secondly, symbols and rituals are defined and their functioning is described. Issues like the interplay between symbol and ritual and society, the way in which order and identity are given to society by symbols and rituals, the way in which symbols and rituals communicate without the use of a multitude of words, the pastoral function that symbols and rituals can fulfil and the gradual disappearance of symbols and rituals from our society are discussed. Attention is also paid to the concepts "liminality" and "commullitas", as described by the anthropologist Victor Turner. These two concepts are central to the understanding of the way in which rituals function. Thirdly, symbols and rituals are viewed from a Biblical and theological angle. The study shows that man was created as a symbol, but also underlines the importance of seeing man's body and soul as a unity. This has special implications for the manner in which we ritualize. It is also pointed out that symbols and rituals have played a major role in worship since the earliest times. The important role which kerugmatic and cultic acts, as well as the sacraments have played and can still play in the life of a believer is also described. Fourthly, the study concludes that symbols and rituals can indeed play a vital role in the process of religious education and the deepening and expansion of faith. The argument is supported in a deductive manner by the insights of people like H. Westerhoff, P. Babin, C.R. Foster, S. McLean and others. It is stressed that symbols and rituals should be used in a nuanced manner. Finally a number of proposals are made as to how these principles could be implemented in practice, together with some suggestions for further study. We believe that this should stimulate both the utilisation of symbols and rituals and further discussion and research in this regard. / AFRIKAANSE OPSOMMING: Daar het die afgelope aantal jare 'n hele aantal teoriee rakende die effektiewe oordrag van geloofsinhoude die lig gesien. Die teoriee word feitlik deurgaans gekenmerk deur 'n holistiese benadering wat beklemtoon dat meer as die kognitiewe en verbale potensiaal van die mens benut behoort te word. Hierdie studie sluit daarby aan, maar soek verder na praktiese instrumente vir geloofsvorming wat aan hierdie vereiste sal voldoen. Die sentrale hipotese van die studie is dat simbole en rituele by uitnemendheid geskik is om geloofsinhoude op 'n holistiese wyse oor te dra en so mee te werk aan 'n proses van geloofsvorming. Daar word in die studie gewys op skuiwe wat die afgelope aantal jare binne die moderne samelewing plaasgevind het en die mens se gedrag, lewens- en wereldbeskouing, asook kommunikasie en teoriee ten opsigte van kommunikasie daadwerklik beinvloed het. Die kompleksiteit van die samelewing word uitgelig omdat dit sowel positiewe as negatiewe implikasies vir die funksionering van simbole en rituele het. Tweedens word simbole en rituele gedefinieer en die funksionering daarvan beskryf Sake soos die wisselwerking tussen simbole en ritue1e en die gemeenskap, die wyse waarop simbole en rituele orde en identiteit aan die gemeenskap gee, die wyse waarop simbole en rituele sonder 'n omhaal van woorde kommunikeer, die pastorale funksies wat deur simbole en ritue1e vervul kan word en die wyse waarop simbole en rituele algaande uit die samelewing verdwyn het, word bespreek. Aandag word ook aan die begrippe "liminaliteit" en "communitas" gegee. Daar word veral aangesluit by die werk van die antropoloog Victor Turner. Hierdie twee begrippe word as wesenlik vir die verstaan van die funksionering van rituele beskou. Derdens word simbole en rituele deur 'n teologiese en Bybelse bril beskou. Ten aanvang word daarop gewys dat daar aan die mens die kwaliteit gegee is om as lewende simbool te funksioneer. Vervolgens word aangetoon hoe be1angrik dit is om die liggaamlikheid van die mens ernstig op te neem en daarna hoedat simbole en rituele vanaf die Bybelse tye 'n sentrale rol gespeel het in die aanbiddingswereld van gelowiges. Die besondere rol wat kerugmatiese en kultiese handelinge, asook die sakramente, in die geloofslewe van mense gespeel het en steeds speel, word bespreek. Vierdens word die gevolgtrekking gemaak dat simbole en rituele inderdaad 'n belangrike rol kan speel in die proses van geloofsvorming. Die argument word verder op deduktiewe wyse ondersteun deur insigte van persone soos J.H. Westerhoff, P. Babin, R. Osmer, C.R. Foster, S. McLean e.a. Daar word veral gewys op die belangrikheid van 'n genuanseerde gebruik van simbole en rituele. Ten slotte word enkele bedieningsvoorstelle en aanbevelings vir verdere navorsing gemaak wat as stimulering van die bedieningspraktyk behoort te dien.

This study reports on recurring difficulties experienced by undergraduate students with respect to understanding and interpretation of certain symbolism, nomenclature, terminology, shorthand notation, models and other visual representations employed in the field of Molecular Biology to communicate information. Based on teaching experience and guidelines set out by a four-level methodological framework, data on various topic-related difficulties was obtained by inductive analyses of students’ written responses to specifically designed, free-response and focused probes. In addition, interviews, think-aloud exercises and student-generated diagrams were also used to collect information. Both unanticipated and recurring difficulties were compared with scientifically correct propositional knowledge, categorized and subsequently classified. Students were adept at providing the meaning of the symbol “Δ” in various scientific contexts; however, some failed to recognize its use to depict the deletion of a leucine biosynthesis gene in the form, Δ leu. “Hazard to leucine”, “change to leucine” and “abbreviation for isoleucine” were some of the erroneous interpretations of this polysemic symbol. Investigations on these definitions suggest a constructivist approach to knowledge construction and the inappropriate transfer of knowledge from prior mental schemata. The symbol, “::”, was poorly differentiated by students in its use to indicate gene integration or transposition and in tandem gene fusion. Idiosyncratic perceptions emerged suggesting that it is, for example, a proteinaceous component linking genes in a chromosome or the centromere itself associated with the mitotic spindle or “electrons” between genes in the same way that it is symbolically shown in Lewis dot diagrams which illustrate covalent bonding between atoms. In an oligonucleotide shorthand notation, some students used valency to differentiate the phosphite trivalent form of the phosphorus atom from the pentavalent phosphodiester group, yet the concept of valency was poorly understood. By virtue of the visual form of a shorthand notation of the 3,5 phosphodiester link in DNA, the valency was incorrectly read. VSEPR theory and the Octet Rule were misunderstood or forgotten when trying to explain the valency of the phosphorus atom in synthetic oligonucleotide intermediates. Plasmid functional domains were generally well-understood although restriction mapping appeared to be a cognitively demanding task. Rote learning and substitution of definitions were evident in the explanation of promoter and operator functions. The concept of gene expression posed difficulties to many students who believed that genes contain the entity they encode. Transcription and translation of in tandem gene fusions were poorly explained by some students as was the effect of plasmid conformation on transformation and gene expression. With regard to the selection of transformants or the hybridoma, some students could not engage in reasoning or lateral thinking as protoconcepts and domain-specific information were poorly understood. A failure to integrate and reason with factual information on phenotypic traits, media components and biochemical pathways were evident in written and oral presentations. DNA-strand nomenclature and associated function were problematic to some students as they failed to differentiate coding strand from template strand and were prone to interchange the labelling of these. A substitution of labels with those characterizing DNA replication intermediates demonstrated erroneous information transfer. DNA replication models posed difficulties integrating molecular mechanisms and detail with line drawings, coupled with inaccurate illustrations of sequential replication features. Finally, a remediation model is presented, demonstrating a shift in assessment score dispersion from a range of 0 - 4.5 to 4 - 9 when learners are guided metacognitively to work with domain-specific or critical knowledge from an information bank. The present work shows that varied forms of symbolism can present students with complex learning difficulties as the underlying information depicted by these is understood in a superficial way. It is imperative that future studies be focused on the standardization of symbol use, perhaps governed by convention that determines the manner in which threshold information is disseminated on symbol use, coupled by innovative teaching strategies which facilitate an improved understanding of the use of symbolic representations in Molecular Biology. As Molecular Biology advances, it is likely that experts will continue to use new and diverse forms of symbolic representations to explain their findings. The explanation of futuristic Science is likely to develop a symbolic language that will impose great teaching challenges and unimaginable learning difficulties to new generation teachers and learners, respectively. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

CAPES / Este trabalho examina a pictografia e sua força de construção representativa na constituição subjetiva das pessoas. A partir do estudo de pictogramas, investigação histórica, da construção simbólica nos preceitos de transformação e construção com o meio, é localizada a pictografia dentro da cultura, da linguagem, da semiótica e da tecnologia, utilizando iconografias de navegação presentes em interfaces de smartphones e criar um modelo de análise a fim de demonstrar o rastro na construção simbólica e subjetiva das pessoas. / The present paper analyzes pictography and its impact on the individual’s subjective nature. By studying pictograms, retracing their historical origins and investigating their symbolic qualities, as well as how those meanings are created and transformed by the environment in which they exist, this paper places pictography within the realms of culture, language, semiotics and technology. It uses the iconography found in smartphone interfaces as the foundation for an analytic model in order to demonstrate the traces left by process of symbolic construction on the individual.
