    Abstract This thesis explores how the general public understands and responds to dementia. In the context of this study the word ‘understanding' is used to convey the complex co-construction of knowledge and establishing of beliefs that constitutes public understandings of dementia. The study also examines the responses of members of the public to dementia, in the context of their understanding. Data were collected over a 12 month period and included a module in the Northern Ireland Life and Times (NILT) survey, five focus groups and nine interviews with participants from the focus groups. The survey module included thirty measures examining levels of knowledge and attitudes towards dementia. 1200 participants were targeted and the survey was administered by the Northern Ireland Research & Statistics Agency with a response rate of 58%. The focus groups and interviews provided the mechanism to gather a more nuanced picture, exploring the beliefs behind the attitudes and the self-reported responses of participants to people with dementia. Findings indicate that the general public has a reasonable knowledge of the symptoms and pathway of dementia in line with a bio medical model. However the findings also indicate that the general public holds a mix of theoretical and empirical knowledge and that this is often contradictory. A complex mix of scientific or medical information, experience, anecdote and assumptions contribute to the discourse. This information is stored and conveyed in the form of stories and a consequence of this interplay is that individual experiences told in the form of stories are generalised to become building blocks in the construction of what the general public understands dementia to be. The current construction of dementia among the general public is found to be both nihilistic and ageist with clear evidence that dementia is stigmatised. I will argue that that the relationship between dementia and ageing in the minds of the general public is a symbiotic one. Dementia has become a cultural metaphor for unsuccessful ageing marking entry to the fourth age. The stigmatising response of the general public is the result of a complex interplay of multiple factors. I have expanded on previous ideas of multiple jeopardy and intersectionality, suggesting that the stigma associated with dementia is unique and driven as much by emotional responses as by the social location of the person with dementia. I have borrowed Brooker’s (2003) term “Dementia-ism’ to describe this stigma. This thesis argues for a more complex and sophisticated approach to changing public attitudes and reducing stigma. Dementia-ism must be addressed with the same strength of purpose currently applied to sexism, racism and ageism

    The challenges of implementing and evaluating a pilot music and movement intervention for people with dementia (innovative practice).

    This paper reports on the challenges associated with implementing and evaluating an innovative pilot music and movement project. The evaluation documents that participants enjoyed the sessions and that they created the opportunity for social engagement although there is little to suggest this is unique to this particular type of intervention. Difficulties included matching the programme to the needs of participants, communicating effectively, and over burdensome paperwork. The paper also comments on the challenges associated with last minute, limited funding opportunities for both the organisation commissioning a project and the team evaluating it. In this case, the evaluation team found that many of the more difficult issues associated with the pilot could have been resolved with more time for planning and preparation

    Purging of inbreeding depression within the Irish Holstein-Friesian population

    The objective of this study was to investigate whether inbreeding depression in milk production or fertility performance has been partially purged due to selection within the Irish Holstein-Friesian population. Classical, ancestral (i.e., the inbreeding of an individual's ancestors according to two different formulae) and new inbreeding coefficients (i.e., part of the classical inbreeding coefficient that is not accounted for by ancestral inbreeding) were computed for all animals. The effect of each coefficient on 305-day milk, fat and protein yield as well as calving interval, age at first calving and survival to second lactation was investigated. Ancestral inbreeding accounting for all common ancestors in the pedigree had a positive effect on 305-day milk and protein yield, increasing yields by 4.85 kg and 0.12 kg, respectively. However, ancestral inbreeding accounting only for those common ancestors, which contribute to the classical inbreeding coefficient had a negative effect on all milk production traits decreasing 305-day milk, fat and protein yields by -8.85 kg, -0.53 kg and -0.33 kg, respectively. Classical, ancestral and new inbreeding generally had a detrimental effect on fertility and survival traits. From this study, it appears that Irish Holstein-Friesians have purged some of their genetic load for milk production through many years of selection based on production alone, while fertility, which has been less intensely selected for in the population demonstrates no evidence of purging

    Lessons Learned in Pooling Data for Reference Populations

    This study set out to demonstrate the feasibility of merging data from 4 different experimental resource dairy populations (1 herd in each of Scotland and Ireland, and 2 in the Netherlands) to create a pooled reference population for joint genetic and genomic analyses. Data included a total of 60,058 weekly records from 1,630 Holstein-Friesian cows across the 4 herds and included 7 traits: milk, fat and protein yield, milk somatic cell count, live weight, dry matter intake, and energy intake and balance. Missing records were predicted using random regression models, so that at the end there were 44 weekly records, corresponding to the typical 305-day lactation, for each cow. Data were subsequently merged and analysed with mixed linear models. Genetic variance and heritability estimates were greater (P0.05) from zero. When estimable, the genetic correlation between herds for the same trait ranged from 0.85 to 0.99. Results suggested that merging experimental herd data into a single dataset is both feasible and sensible, despite potential differences in management and recording of the animals in the four herds. Merging experimental data will increase the precision of parameter estimates in a genetic analysis and augment the potential reference population in genome-wide association studies especially of difficult-to-record traits
