FROM LINE-DRAWINGS TO IMPRESSIONS OF 3D OBJECTS - DEVELOPING A MODEL TO ACCOUNT FOR THE SHAPES THAT PEOPLE SEE

The interpretations people attach to line drawings reflect shape-related processes in human vision. Their divergences from expectations embodied in related machine vision traditions are summarized, and used to suggest how human vision decomposes the task of interpretation. A model called IO implements this idea. It first identifies geometrically regular, local fragments. Initial decisions fix edge orientations, and this information constrains decisions about other properties. Relations between fragments are explored, beginning with weak consistency checks and moving to fuller ones. IO's output captures multiple distinctive characteristics of human performance, and it suggests steady progress towards understanding shape-related visual processes is possible.

Design optimization of cold-formed steel portal frames taking into account the effect of building topology

Cold-formed steel portal frames are a popular form of construction for low-rise commercial, light industrial and agricultural buildings with spans of up to 20 m. In this article, a real-coded genetic algorithm is described that is used to minimize the cost of the main frame of such buildings. The key decision variables considered in this proposed algorithm consist of both the spacing and pitch of the frame as continuous variables, as well as the discrete section sizes.A routine taking the structural analysis and frame design for cold-formed steel sections is embedded into a genetic algorithm. The results show that the real-coded genetic algorithm handles effectively the mixture of design variables, with high robustness and consistency in achieving the optimum solution. All wind load combinations according to Australian code are considered in this research. Results for frames with knee braces are also included, for which the optimization achieved even larger savings in cost.

Narrative on the Net:Bill and his hyper- lives, loves and texts

Narrative, by its very nature, is changing as a consequence of internet developments. Hypertexts are, for example, changing not just the way in which we disseminate information, but also the ways in which we write, speak and think. In this paper a narrative approach is taken to assess a case study of a person’s extensive home site on the web. Bill maintains an extensive web site documenting his life with Parkinson’s Disease, his love for running and all matters relating to the island of Montserrat in the Eastern Caribbean. Bill’s Parkinson’s Disease hypertext diary forms the focus of this case study of a life spent on-line. Though set up just as a diary about this progressively degenerative disease, because of its hypertextual qualities, this paper argues that it is through the diary that Bill comes to produce and sustain - to narrate - his identity. This paper thus contributes to the position that though hypertext encourages the construction of fragmented and false identity narratives, it is also a medium for sustaining linear and coherent representations of self-identity.

Vision and Virtuality:The Construction of Narrative Space in Film and Computer Games

This paper seeks to explore the construction of narrative space in 3D PC computer games. With reference to Stephen Heath’s theory of filmic narrative space, the paper will examine how computer games, based on the rendition of a continuous 3D, real-time interactive environment, construct a distinct mode of narrativisation. The dynamic imbrication of the manipulation of 3D objects in a virtual world and the (re)presentation of this virtual mise-en-scene constitute an interaction that affects the concept of narrative in computer games. This leads to several questions that the paper seeks to investigate: How does the construction of space in PC games contribute to the meaning-making process or the gamer’s experience of narrative? How then is this experience of narrative game-space different from that of film?

Just what is narrative urgency?

This article takes as its main point of departure a body of empirical research on reading and text processing, and makes particular reference to the type of experiments conducted in Egidi and Gerrig (2006) and Rapp and Gerrig (2006). Broadly put, these experiments (i) explore the psychology of readers’ preferences for narrative outcomes, (ii) examine the way readers react to characters’ goals and actions, and (iii) investigate how readers tend to identify with characters’ goals the more ‘urgently’ those goals are narrated. The present article signals how stylistics can productively enrich such experimental work. Stylistics, it is argued, is well equipped to deal with subtle and nuanced variations in textual patterns without losing sight of the broader cognitive and discoursal positioning of readers in relation to these patterns. Making particular reference to what might constitute narrative ‘urgency’, the article develops a model which amalgamates different strands of contemporary research in narrative stylistics. This model advances and elaborates three key components: a Stylistic Profile, a Burlesque Block and a Kuleshov Monitor. Developing analyses of, and informal informant tests on, examples of both fiction and film, the article calls for a more rounded and sophisticated understanding of style in empirical research on subjects’ responses to patterns in narrative.

USING ‘NUTRITIONAL NARRATIVE’ AND FOCUS GROUPS TO UNDERSTAND HOW NUTRITIONAL CARE CAN BETTER PRIORITISED FOR OLDER PEOPLE IN HOSPITAL SETTINGS

Introduction: Poor nutritional status among older people is well documented with 40% of older people reported as malnourished on hospital admission. Poor nutrition contributes to increased infection, poorer patient outcomes and death and longer hospital stays. In this study, we assessed the ‘nutrition narrative’ from older hospital patients together with nutrition knowledge among nursing and medical staff and students.
Methods: The study used a convenience sample of older people (30, mean age 82 years) in two large geographically separate city hospitals. Patients mentally alert and consenting, gave a recorded ‘nutrition narrative’ to get a sense of how they felt their nutritional needs were being met in hospital. Main themes were identified by grounded analysis framework. Focus groups were recruited from medical/nursing teachers and students to assess their working knowledge of nutrition and the nutritional needs of the older patient group.
Results: Analysis of the ‘nutrition narrative’ suggested several themes (i) staff should listen to patients' needs/wishes in discussion with themselves and family members (ii) staff should continue to encourage and progress a positive eating experience (iii) staff should monitor food eaten/or not eaten and increase regular monitoring of weight. The focus groups with medical and nursing students suggested a limited knowledge about nutritional care of older people and little understanding about roles or cross-talk about nutrition across the multidisciplinary groups.
Conclusions: The ‘nutrition narrative’ themes suggested that the nutritional experience of older people in hospital can and must be improved. Nursing and medical staff providing medical and nursing care need better basic knowledge of nutrition and nutritional assessment, an improved understanding of the roles of the various multidisciplinary staff and of hospital catering pathways. Care professionals need to prioritise patient nutrition much more highly and recognise nutritional care as integral to patient healing and recovery

Marie Sallé, Handel, Rameau and the development of narrative dance music:Bericht vom Internationalen Symposium an der Hochschule fur Musik und Theater Leipzig

Paradigmatic analysis reveals that these two composers developed distinct responses to creating narrative in dance music

Paranoia and self-concepts in psychosis: A systematic review of the literature.

The purpose of the present study was to review systematically, research exploring the relationship between self-concepts and paranoia in psychosis. A literature search was performed by two independent raters in relevant databases (MedLine, PsychInfo and Web of Science) and articles meeting the inclusion criteria were cross-referenced. Following scrutiny according to inclusion criteria, 18 studies were selected for review. A narrative synthesis of findings, in which methodological variability is discussed, is presented relative to three key areas: the nature of the relationship between paranoia and self-concepts; the association between paranoia and discrepancies in self-concepts; the nature of the relationship between paranoia and self-concepts when other, dimensional aspects of these constructs are taken into account. The systematic literature review indicated relatively consistent findings, that paranoia is associated with more negative self-concepts when measured cross-sectionally. Results are somewhat more mixed in regards to research on paranoia and self-concept discrepancies. Studies investigating dimensional aspects of self-concepts and paranoia yield findings of particular interest, especially in regards to the association indicated between instability of self-concepts and paranoia. Limitations in research and of the present systematic review are discussed. Clinical and theoretical implications of findings are outlined and possible directions for future research are suggested.
