Latitude and longitude vertical disparities

The literature on vertical disparity is complicated by the fact that several different definitions of the term “vertical disparity” are in common use, often without a clear statement about which is intended or a widespread appreciation of the properties of the different definitions. Here, we examine two definitions of retinal vertical disparity: elevation-latitude and elevation-longitude disparities. Near the fixation point, these definitions become equivalent, but in general, they have quite different dependences on object distance and binocular eye posture, which have not previously been spelt out. We present analytical approximations for each type of vertical disparity, valid for more general conditions than previous derivations in the literature: we do not restrict ourselves to objects near the fixation point or near the plane of regard, and we allow for non-zero torsion, cyclovergence, and vertical misalignments of the eyes. We use these expressions to derive estimates of the latitude and longitude vertical disparities expected at each point in the visual field, averaged over all natural viewing. Finally, we present analytical expressions showing how binocular eye position—gaze direction, convergence, torsion, cyclovergence, and vertical misalignment—can be derived from the vertical disparity field and its derivatives at the fovea

The experience of retirement: a sociological analysis

The retirement experience is examined in this thesis via interviews with four groups - residents in an inner city area miners, car workers and architects The purpose behind these interviews is to explore the everyday experience of retirement relating this experience both to the immediate structures surrounding the individual and to broader economic and political forces. As well as giving detailed descriptions of the retirement experience, this thesis is also concerned with theoretical issues in the field of social gerontology. Here, I have reviewed the main sociological theories and have indicated the outline of an alternative approach. As a final aim of the thesis, I have tried to integrate some of the arguments advanced, with a discussion about the components of a retirement social policy, relating the necessity for such a policy both to the ending of life-time employment and the movement towards an ageing of the population. Further, I have attempted to illustrate the effect of these changes via the interviews conducted for this study, building the elements of a social policy for retirement both on the latter, and on extrapolations about future social changes

Branding: an adolescent sun protection perspective

Australian adolescents are consistently found to exhibit low levels of adherence to sun protection guidelines, resulting in high levels of skin cancer incidence in later life. Given the importance of image, appearance, and peer approval factors in adolescent sun protection, this study sought to examine adolescents’ perceptions of the “sun protection brand,” its competing brands, and possible complementary brands. A series of 14 focus groups were conducted with adolescents in Years 9 and 10 (junior high school), and the results are examined in the context of potential branding-related marketing strategies to overcome some of the barriers to sun protection

Older patients\u27 attitudes to general practice registrars: a qualitative study

Background Research suggests that older patients may be reluctant to engage general practice registrars (GPRs) in their care. The authors undertook a qualitative study of the attitudes of older patients to GPRs to investigate this issue. Method Thirty-eight patients aged 60 years and over from three training practices participated in semistructured telephone interviews, which explored patients responses to GPRs. The interviews were recorded, transcribed and analysed using a template analysis approach. Results Analysis of the interviews produced five major themes concerning patient attitudes to GPRs: desire for continuity, desire for access, openness, trust and a desire for meaningful communication. Discussion Older patients attitudes to GPRs cannot be viewed in isolation from their relationship with their usual general practitioner, and this needs to be taken into account when engaging GPRs in the care of older patients. Systems need to be developed to maintain relational and informational continuity with older patients\u27 regular GPs

Using health risk assessments to target and tailor: An innovative social marketing program in aged care facilities

The number of Australians over the age of 65 years is expected to double by 2021. Many older Australians suffer from one or more chronic diseases - including cancer, coronary heart disease, respiratory diseases (AIHW, 2009) resulting in increased morbidity and mortality, lower quality of life and a higher need for health care (Hickey and Stilwell, 1991). There is increasing evidence that the adoption of healthy lifestyles can have significant benefits even into older age (Haveman-Nies et al, 2002). This project utilized a social marketing framework to support aged residents of retirement homes to adopt healthy lifestyle behaviours to improve their health

Participatory social network map making with family carers of people living with dementia

This article focuses on the use of a participatory social network mapping method with family carers. This is one of a suite of methods developed in a 5-year qualitative multi-centre project exploring how neighbourhoods support, enable or disable people with dementia and their families to live well in their communities. The article considers how mapping provides insights into family support networks, revealing the fluidity of support and care within relationships as well as providing opportunity for individuals to represent the complexities of their relationships with more and less significant others. However, the potential offered by the approach goes beyond those of visual representations of networks and contacts. Paying attention to the co-production process, as well as the reflexive dialogue that emerges in the exchange between researcher, participants, and the maps themselves, we consider how the maps emerge as affective artifacts, weighted with emotion
