Exocentric direction judgements in computer-generated displays and actual scenes

One of the most remarkable perceptual properties of common experience is that the perceived shapes of known objects are constant despite movements about them which transform their projections on the retina. This perceptual ability is one aspect of shape constancy (Thouless, 1931; Metzger, 1953; Borresen and Lichte, 1962). It requires that the viewer be able to sense and discount his or her relative position and orientation with respect to a viewed object. This discounting of relative position may be derived directly from the ranging information provided from stereopsis, from motion parallax, from vestibularly sensed rotation and translation, or from corollary information associated with voluntary movement. It is argued that: (1) errors in exocentric judgements of the azimuth of a target generated on an electronic perspective display are not viewpoint-independent, but are influenced by the specific geometry of their perspective projection; (2) elimination of binocular conflict by replacing electronic displays with actual scenes eliminates a previously reported equidistance tendency in azimuth error, but the viewpoint dependence remains; (3) the pattern of exocentrically judged azimuth error in real scenes viewed with a viewing direction depressed 22 deg and rotated + or - 22 deg with respect to a reference direction could not be explained by overestimation of the depression angle, i.e., a slant overestimation

Dogs and monsters: moral status claims in the fiction of Dean Koontz

This article explores conceptions of moral status in the work of American thriller author Dean Koontz. It begins by examining some of the general theories of moral status used by philosophers to determine whether particular entities have moral status. This includes both uni-criterial theories and multi-criterial theories of moral status. After this examination, the article argues for exploring bioethics conceptions in popular fiction. Popular fiction is considered a rich source for analysis because it provides not only a good approximation of the beliefs of ordinary members of the moral community, but also explores important issues in a context where ordinary individuals are likely to encounter them. Following on from this, the article then explores theories of moral status in the context of Koontz’s novels. In particular, the article focuses on the novel Watchers and Koontz’s Frankenstein series. Through these works, Koontz indicates that entities have moral status for a variety of reasons and thus presumably, he is a proponent of multi-criterial theories of moral status. The article concludes with an examination of what this might mean for our understanding of moral status claims generally

The responsibilities of conscience in healthcare decisions: moving towards a collaborative framework

Claims of conscience are a substantial area of concern in relation to healthcare decisions but are often only considered in a limited context. Broadening our understanding of claims of conscience, however, might lead to claims that we are moving back towards a doctor-centred understanding of medical care. This article argues that we can allow claims of conscience without unduly penalising patients by focusing on the responsibilities that ought to attach to conscience claims. This article sets out three responsibilities – humility, universality, and reciprocal respect – which ought to be part of any claim of conscience. The Charlie Gard case is then used as an example to explore the use of responsibilities. The article then moves to consider possible issues that arise from this view

BECOMING: an analysis of narratives describing the experiences of nurses who have undertaken training in solution focused brief therapy.

This thesis is a study of the experiences of nurses who have undertaken training in Solution Focused Brief Therapy (SFBT). While the clinical outcomes of using SFBT, and other psychological therapies, to treat clients have been the subject of much research, the outcomes of training therapists to use SFBT has been relatively unexplored. It is, therefore, my intention to address, in part, this uncharted area of practice. Utilising a mixed methodology, the study is divided into two Stages. In Stage I, an original Solution Focused (SF) methodology is developed and used to conduct individual interviews with twenty participants. Interviews are transcribed and treated as narrative texts, and are then subjected to multi-factored analysis enabling the synthesis of a group narrative and the construction of a typology of experience. In Stage II, I conduct further in-depth interviews with three of the original participants and utilise a hermeneutic methodology, drawing on the work of Hans-Georg Gadamer, to engage with the texts generated from these interviews. The texts are explored thematically, and through the nursing metaparadigm of Jacqueline Fawcett, and are compared with a metaparadigm of SF practice. The research suggests that training is SFBT can have a profound effect on the clinical practice, and professional identity, of nurses, and that this is related to the paradigm of nursing which informs their practice. Where the nursing paradigm is of the dominant assessment and delivery of care needs modality, SFBT training has little to offer the nurse; however, where the nursing paradigm reflects an interpersonal, dynamic modality based on shared relationships, training in SFBT can be a transformative experience for the nurse. This research makes an original contribution to the field of SFBT and to our understanding of the relationship between SFBT and nursing. Building on the work of earlier scholars, it argues that SFBT is congruent with some nursing paradigms, and not all nursing paradigms as previously suggested. It also advances our understanding of how the scope and field of SF practice may be delineated

THE IMPACT OF AN AGING RURAL POPULATION ON LOCAL TAX STRUCTURES

The growing American retired population increasingly is viewed for its economic development potential. The relationship between the elderly and local taxes may have a critical effect on this potential, however. This paper examines the local tax implications of an increasing elderly population in communities prohibiting tax referenda. In such communities, citizens have no direct role in tax decisions. The elderly's attitudes towards different local taxes are examined using telephone survey data, before using aggregate data to investigate the relationship between the elderly and the specific taxes used in communities. The results suggest that a high proportion of elderly do not affect the mix of local taxes, but that an increasing proportion does have an influence.Community/Rural/Urban Development,

ANALYSIS OF CHANGING METHODS OF VERTICAL COORDINATION IN THE PORK INDUSTRY

This study examines the motivation behind contracts and vertical integration in the pork industry, and simulates the effects of potential improvements in coordination. Incentives related to lowering costs of measuring and sorting hogs, and protecting against opportunistic behavior associated with specific assets, can result in hog quality improvements. A framework for simulating the effects of increased coordination through contracts and vertical integration was developed and used to evaluate potential improvements in leanness. Although simulations suggest only modest changes in pork prices and supplies, gains in consumers' surplus could be substantial for larger demand shifts due to quality improvements.Contracts, Hogs, Lean pork, Simulation model, Vertical coordination, Vertical integration, Industrial Organization, Livestock Production/Industries,

Strategic Alliances in U.S. Branded Beef Programs

In this paper, we combine concepts from organizational economics to examine supply chain alliances formed to market branded beef products. To illustrate application of the framework, we examine three different types of alliances. We conclude that measuring costs associated with quality attributes have an important role in alliance structure.Agribusiness,
