    This research investigates the reciprocal spatial impact of universities and their host cities. The study carries out a cross-case analysis between the University of Lincoln and city of Lincoln and with the University of Worcester and the city of Worcester. Both cities are located in United Kingdom (UK), have similar historical backgrounds, and are similar in terms of size and population demographic. Additionally, both universities are relatively new universities. This study attempts to uncover and clarify how the University of Worcester and the University of Lincoln have transformed their socio-economic and spatial environments in their respective cities. One of the most significant features of this transformation is related to spatial integration and connectivity between the campus and city. This is a complex relationship, that is dependent on many physical and non-physical variables. This paper presents the results of that highlight the spatial configuration of the city/ campus relationship. Space Syntax techniques and observation data are adapted in order to show how campus layouts influence the spatial configuration of the city. The main finding in this research shows that the location of a university campus has a significant impact on the city in physical, social and economic forms

    This dissertation investigates schematisation of computer-generated tactile orientation maps that support mediation of spatial knowledge of unknown urban environments. Computergenerated tactile orientation maps are designed to provide the blind with an overall impression of their surroundings. Their details are displayed by means of elevated features that are created by embossers and can be distinguished by touch. The initial observation of this dissertation states that only very little information is actually transported through tactile maps owing to the coarse resolution of tactual senses and the cognitive effort involved in the serial exploration of tactile maps. However, the differences between computer-generated, embossed tactile maps and manufactured, deep-drawn tactile maps are significant. Therefore the possibilities and confines of communicating information through tactile maps produced with embossers is a primary area of research. This dissertation has been able to demonstrate that the quality of embossed prints is an almost equal alternative to traditionally manufactured deep-drawn maps. Their great advantage is fast and individual production and (apart from the initial procurement costs for the printer)low price, accessibility and easy understanding without the need of prior time-consuming training. Simplification of tactile maps is essential, even more so than in other maps. It can be achieved by selecting a limited number from all map elements available. Qualitative simplification through schematisation may present an additional option to simplification through quantitative selection. In this context schematisation is understood as cognitively motivated simplification of geometry and synchronised maintenance of topology. Rather than further reducing the number of displayed objects, the investigation concentrates on how the presentation of different forms of streets (natural vs. straightened) and junctions (natural vs. prototypical) affects the transfer of knowledge. In a second area of research, a thesis establishes that qualitative simplification of tactile orientation maps through schematisation can enhance their usability and make them easier to understand than maps that have not been schematised. The dissertation shows that simplifying street forms and limiting them to prototypical junctions does not only accelerate map exploration but also has a beneficial influence on retention performance. The majority of participants that took part in the investigation selected a combination of both as their preferred display option. Tactile maps that have to be tediously explored through touch, uncovering every detail, complicate attaining a first impression or an overall perception. A third area of research is examined, establishing which means could facilitate map readersĂą options to discover certain objects on the map quickly and without possessing a complete overview. Three types of aids are examined: guiding lines leading from the frame of the map to the object, position indicators represented by position markers at the frame of the map and coordinate specifications found within a grid on the map. The dissertation shows that all three varieties can be realised by embossers. Although a guiding line proves to be fast in size A4 tactile maps containing only one target object and few distracting objects, it also impedes further exploration of the map (similar to the grid). In the following, advantages and drawbacks of the various aids in this and other applications are discussed. In conclusion the dissertation elaborates on the linking points of all three examinations. They connect and it is argued that cognitively motivated simplification should be a principle of construction for embossed tactile orientation maps in order to support their use and comprehension. A summary establishes the recommendations that result from this dissertation regarding construction of tactile orientation maps considering the limitations through embosser constraints. Then I deliberate how to adapt schematisation of other maps contingent to intended function, previous knowledge of the map reader, and the relation between the time in which knowledge is acquired and the time it is employed. Closing the dissertation, I provide an insight into its confines and deductions and finish with a prospective view to possible transfers of the findings to other applications, e.g. multimedia or interactive maps on pin-matrix displays and devices

    Connaßtre la géographie de son environnement urbain est un enjeu important pour les personnes déficientes visuelles. Des cartes tactiles en relief sont généralement utilisées mais elles présentent des limitations importantes (nombre limité d'informations, recours à une légende braille). Les nouvelles technologies permettent d'envisager des solutions innovantes. Nous avons conçu et développé une carte interactive accessible, en suivant un processus de conception participative. Cette carte est basée sur un dispositif multi-touch, une carte tactile en relief et une sortie sonore. Ce dispositif permet au sujet de recueillir des informations en double-cliquant sur certains objets de la carte. Nous avons démontré expérimentalement que ce prototype était plus efficace et plus satisfaisant pour des utilisateurs déficients visuels qu'une carte tactile simple. Nous avons également exploré et testé différents types d'interactions avancées accessibles pour explorer la carte. Cette thÚse démontre l'importance des cartes tactiles interactives pour les déficients visuels et leur cognition spatiale.Knowing the geography of an urban environment is crucial for visually impaired people. Tactile relief maps are generally used, but they retain significant limitations (limited amount of information, use of braille legend, etc.). Recent technological progress allows the development of innovative solutions which overcome these limitations. In this thesis, we present the design of an accessible interactive map through a participatory design process. This map is composed by a multi-touch screen with tactile map overlay and speech output. It provides auditory information when tapping on map elements. We have demonstrated in an experiment that our prototype was more effective and satisfactory for visually impaired users than a simple raised-line map. We also explored and tested different types of advanced non-visual interaction for exploring the map. This thesis demonstrates the importance of interactive tactile maps for visually impaired people and their spatial cognition

    City/Campus Duality: Spatial Impact of University Campuses on Cities with reference to Lincoln, Worcester and Bath, UK

    Get PDF
    This research presents a critical investigation and analysis of the spatial configuration of three spatially similar cities and universities. Albeit, these cities are with different distributions of university campus accessibility and location in their cities. The research attempts to present a new approach to the conceptualization of relationship, between universities and cities, through an analytical investigation of the structure of urban space. This conception is the subject of investigation through a comparative analysis of urban structure in the University of Lincoln and Lincoln city, the University of Worcester and Worcester city, and the University of Bath and Bath city. Also, it shows that the spatial configuration of the city is influenced by the university, not only in terms of a various set of social elements, which include the urban structure such as the socio-economic environment, but also in terms of physical morphology. The aim of this study is to conduct an investigation into the spatial relationship between the university and the city from a theoretical viewpoint, which is informed by the notions of space and spatiality in an attempt to unveil the impact of university on the city, in terms of both physical and spatial relationship. This study utilises a mixed methods research to investigate and understand the relationship between universities and cities. These include a critical literature investigation, Space syntax analysis, Observation, interviews and socio-economic analysis. The finding indicated that the physical location of campuses has a direct impact of the relationship between universities and cites. However, there is no direct relationship between socio-economic impact and physical location of the campuses within cities. The results support that the city/campus duality is complex and it is based on a variety of indictors from socio-economic and socio-spatial points of view. Therefore, this relationship is bilateral. This thesis develops a new assessment tool to measure the quality of the relationship between university and city. Through the methodology and data analysis, this research provides guidelines for creating new insights into how cities and universities engage one another. The findings of this empirical study can be adopted as a compelling strategy for creating positive urban space within a campus utilising such critical investigation and syntax of campus-cities. The outcome of this study will form the basis for further development and planned growth of the universities and cities presented in this thesis

    An ontological analysis of vague motion verbs, with an application to event recognition

    Get PDF
    This research presents a methodology for the ontological formalisation of vague spatial concepts from natural language, with an application to the automatic recognition of event occurrences on video data. The main issue faced when defining concepts sourced from language is vagueness, related to the presence of ambiguities and borderline cases even in simple concepts such as ‘near’, ‘fast’, ‘big’, etc. Other issues specific to this semantic domain are saliency, granularity and uncertainty. In this work, the issue of vagueness in formal semantics is discussed and a methodology based on supervaluation semantics is proposed. This constitutes the basis for the formalisation of an ontology of vague spatial concepts based on classical logic, Event Calculus and supervaluation semantics. This ontology is structured in layers where high-level concepts, corresponding to complex actions and events, are inferred through mid-level concepts, corresponding to simple processes and properties of objects, and low-level primitive concepts, representing the most essential spatio-temporal characteristics of the real world. The development of ProVision, an event recognition system based on a logic-programming implementation of the ontology, demonstrates a practical application of the methodology. ProVision grounds the ontology on data representing the content of simple video scenes, leading to the inference of event occurrences and other high-level concepts. The contribution of this research is a methodology for the semantic characterisation of vague and qualitative concepts. This methodology addresses the issue of vagueness in ontologies and demonstrates the applicability of a supervaluationist approach to the formalisation of vague concepts. It is also proven to be effective towards solving a practical reasoning task, such as the event recognition on which this work focuses

    The Agency of Art Objects in Northern Europe, 1380–1520

    Get PDF
    This monograph book offers a new interpretation of northern European art of the fifteenth century. The author presents it as a conglomerate of objects-things which act on the recipient in a specific – material and spatial – way. He analyzes macro-scale objects that impose movement on the viewer, and micro-scale objects that encourage manipulation. Inspired by the anti-anthropocentric concept of “returning to things” (B. Latour, A. Gell and others), the author searches for the “agency of things” in late-medieval art objects, which evoke specific liturgical, devotional, propaganda-political behaviors, or establish the status of social owner of the object that once co-created the network of material and spiritual culture. This methodologically innovative approach is part of the latest research in early art in Western Europe and the United States

    Clothing Sacred Scriptures

    According to a longstanding interpretation, book religions are agents of textuality and logocentrism. This volume inverts the traditional perspective: its focus is on the strong dependency between scripture and aesthetics, holy books and material artworks, sacred texts and ritual performances. The contributions, written by a group of international specialists in Western, Byzantine, Islamic and Jewish Art, are committed to a comparative and transcultural approach. The authors reflect upon the different strategies of »clothing« sacred texts with precious materials and elaborate forms. They show how the pretypographic cultures of the Middle Ages used book ornaments as media for building a close relation between the divine words and their human audience. By exploring how art shapes the religious practice of books, and how the religious use of books shapes the evolution of artistic practices this book contributes to a new understanding of the deep nexus between sacred scripture and art

    Effects of forensically-relevant facial concealment on acoustic and perceptual properties of consonants

    Get PDF
    This thesis offers a thorough investigation into the effects of forensically-relevant facial concealment on speech acoustics and perception. Specifically, it explores the extent to which selected acoustic-phonetic and auditory-perceptual properties of consonants are affected when the talker is wearing ‘facewear’ while speaking. In this context, the term ‘facewear’ refers to the various types of face-concealing garments and headgear that are worn by people in common daily communication situations; for work and leisure, or as an expression of religious, social and cultural affiliation (e.g. surgical masks, motorcycle helmets, ski and cycling masks, or full-face veils such as the niqāb). It also denotes the face or head coverings that are typically used as deliberate (visual) disguises during the commission of crimes and in situations of public disorder (e.g. balaclavas, hooded sweatshirts, or scarves). The present research centres on the question: does facewear influence the way that consonants are produced, transmitted, and perceived? To examine the effects of facewear on the acoustic speech signal, various intensity, spectral, and temporal properties of spoken English consonants were measured. It was found that facewear can considerably alter the acoustic-phonetic characteristics of consonants. This was likely to be the result of both deliberate and involuntary changes to the talker’s speech productions, and of sound energy absorption by the facewear material. The perceptual consequences of the acoustic modifications to speech were assessed by way of a consonant identification study and a talker discrimination study. The results of these studies showed that auditory-only and auditory-visual consonant intelligibility, as well as the discrimination of unfamiliar talkers, may be greatly compromised when the observer’s judgements are based on ‘facewear speech’. The findings reported in this thesis contribute to our understanding of how auditory and visual information interact during natural speech processing. Furthermore, the results have important practical implications for legal cases in which speech produced through facewear is of pivotal importance. Forensic speech scientists are therefore advised to take the possible effects of facewear on speech into account when interpreting the outcome of their acoustic and auditory analyses of evidential speech recordings, and when evaluating the reliability of earwitness testimony

    The Invariant in Phonology. The role of salience and predictability

    Get PDF
    This aim of this thesis is to give a phonological account of acoustic variation and reduction. It is argued that phonological representations are uneven and include information about the relative strength of the segmental and subsegmental units composing them. This unevenness implies a distinction between the invariant – the “phonetic essence” of a word, which is practically undeletable – and other units which can be dispensed with under certain circumstances. In the first chapter I compare different theoretical approaches to the problem of acoustic variation, in particular with reference to generative phonology and exemplar-based theories. In the second chapter I propose a model which combines aspects of Optimality Theory, Element Theory and usage-based linguistics. Additionally, I discuss the role of acoustic salience in the formation of the invariant. In chapter three, typological and experimental data are examined in order to establish a salience scale for consonants. In chapter four, the results of the acoustic analysis of four dialogues extracted from a corpus of spoken Italian are presented. As expected, highly salient consonants are preserved to a greater extent than less salient ones. In chapter five I attempt to identify the phonological correlates of acoustic salience and discuss other factors which may favor reduction and deletion, among which predictability. In chapter six I draw some conclusions, deal with some pending issues and suggest future directions for research
