Food choice by people with intellectual disabilities at day centres: A qualitative study
People with intellectual disabilities experience a range of health inequalities. It is important to investigate possible contributory factors that may lead to these inequalities. This qualitative study identified some difficulties for healthy eating in day centres. (1) Service users and their family carers were aware of healthy food choices but framed these as diets for weight loss rather than as everyday eating. (2) Paid carers and managers regarded the principle of service user autonomy and choice as paramount, which meant that they felt limited in their capacity to influence food choices, which they attributed to the home environment. (3) Carers used food as a treat, a reward and for social bonding with service users. (4) Service users’ food choices modelled other service users’ and carers’ choices at the time. It is suggested that healthy eating should be made more of a priority in day care, with a view to promoting exemplarily behaviour that might influence food choice at home
Development, initial validation and reliability testing of a web-based, generic feline health-related quality of life instrument
Objectives:
The objective of this study was to develop a valid, reliable web-based, generic feline health-related quality-of-life (HRQoL) questionnaire instrument to measure the affective impact of chronic disease.
Methods:
A large initial item pool, obtained through interviews with cat owners, was reduced using predetermined criteria, survey scores for relevance and clarity, and the ability of individual items to discriminate between healthy and sick cats when owners completed a prototype questionnaire. Using these data, factor analysis was used to derive a scoring algorithm and provide evidence for factorial validity. Validity was demonstrated further in a field trial using a ‘known groups’ approach (sick vs healthy cats will have a different HRQoL profile, and the HRQoL profile of cats will deteriorate as comorbidities increase). Test–retest reliability was assessed using intra-class correlation coefficients (ICC).
Results:
In total, 165 items were reduced to 20 and, on the basis of a factor analysis that explained 72.3% of the variation in scores input by 71 owners of 30 healthy and 41 sick cats using the prototype, these were allocated to three domains (vitality, comfort and emotional wellbeing [EWB]) with a scoring algorithm derived using item loadings. Subsequently, the owners of 36 healthy and 58 sick cats completed one or two (n = 48) assessments. Median scores (healthy vs sick) for all domains were significantly different (P <0.001), 78% of cats were correctly classified as healthy or sick and for comorbidities the correlation coefficients were moderate (vitality 0.64; comfort 0.63; EWB 0.50). Test–retest reliability was good (ICC vitality 0.635; comfort 0.716; EWB 0.853).
Conclusions and relevance:
This study provides initial evidence for the validity and reliability of a novel HRQoL instrument to aid the assessment and management of chronic diseases of cats
Tests of Five Metal Model Propellers with Various Pitch Distributions in a Free Wind Stream and in Combination with Model VE-7 Fuselage
This report describes the tests of five adjustable blade metal model propellers both in a free wind stream and in combination with a model fuselage with stub wings. The propellers are of the same form and cross section but have variations in radial distributions of pitch. By making a survey of the radial distribution of air velocity through the propeller plane of the model fuselage it was found that this velocity varies from zero at the hub center to approximately free stream velocity at the blade tip. The tests show that the efficiency of a propeller when operating in the presence of the airplane is, over the working range, generally less than when operating in a free wind stream, but that a propeller with a radial distribution of pitch of the same nature as the radial distribution of air velocity through the propeller plane suffers the smallest loss in efficiency
A new method for the prediction of airplane performance
A new method for the prediction of airplane performance in level and climbing flight, together with complete information regarding propeller speeds, is described in this report. Developed from Bairstow's system and making use of American absolute coefficients, this method has advantages of simplicity and brevity
Optimising outputs from a validated online instrument to measure health-related quality of life (HRQL) in dogs
Measurement of health-related quality of life (HRQL) is becoming increasingly valuable within veterinary preventative health care and chronic disease management, as well as in outcomes research. Initial reliability and validation of a 22 item shortened version of VetMetrica (VM), structured questionnaire instrument to measure HRQL in dogs via a mobile application was reported previously. Meaningful interpretation and presentation of the 4 domain scores comprising the HRQL profile generated by VM is key to its successful use in clinical practice and research. Study one describes transformation of domain scores from 0–6 to 0–100 and normalisation of these based on the healthy canine population in two age ranges, such that a score of 50 on a 0–100 scale represents the score for the age-related average healthy dog, and establishment of a threshold to assess domain-specific health status for individual dogs. This provides the clinician with a simple method of ascertaining the health status of an individual dog relative to the average healthy population in the same age group (norm-based scoring). Study two determines the minimum important difference (MID) in domain scores which represents the smallest improvement in score that is meaningful to the dog owner, thus providing the clinician with a means of recognising what is likely to be a significant improvement in scores for an individual dog over time. Visual representation of these guidelines for the purpose of interpreting VM profile scores is presented using case studies
The influence of taphonomy on histological and isotopic analyses of treated and untreated buried modern human bone
The chemical (e.g., preservation/embalming) treatment of skeletal remains can reduce overall DNA quality and quantity. The histological and stable isotope examination of treated and untreated human remains improves our understanding of how chemical preservatives impact bone diagenesis and will determine if chemical treatment adversely affects stable isotope ratio analysis of collagen. Fidelity in the application(s) of stable isotope interpretations requires that the isotope delta (δ) values have not been altered postmortem. Re-associated antimeres and refits of chemically treated and untreated rib and long bones from eight casualties [thin-sectioned human bone (n = 43) and collagen extraction/stable isotope analysis (n = 42)] from the World War II Battle of Tarawa were examined to compare skeletal elements from the same individual that had different taphonomic histories. Histological analyses included scoring upon the Oxford Histological Index (OHI) and Birefringence scale, recording microbial invasion, and general observations. The collected data were analyzed via simple descriptive statistics and paired samples t-tests. Treated remains scored higher on the OHI and for Birefringence, indicating that bone quality was good to excellent. The untreated samples scored lower on the OHI and Birefringence scales suggesting poorer preservation than the treated remains. Histology results were supported by the isotope sample preparation results: the collagen % yield was higher for treated bone than untreated bone. Additionally, chemical preservation had no meaningful impact on isotope δ values of treated and untreated remains from the same element or pair-matched elements. Overall, treated remains exhibited good preservation while untreated remains exhibit poorer preservation with significant microfocal destruction to the extent that little histological analyses can be applied. Stable isotope ratio analysis is viable for both treated and untreated remains indicating this testing modality likely can be used for most treated remains, regardless of origin
Evaluating a partnership model of hospice enabled dementia care: A three-phased monitoring, focus group and interview study
BACKGROUND: People with dementia and their caregivers often lack equitable access to hospice care which is a concern internationally. Domains of best practice in palliative care for this population exist and hospices are urged to become dementia friendly. AIM: This study aimed to evaluate the model of ‘Hospice Enabled Dementia Partnership’ mapped to international domains of best practice. DESIGN: Three-phased monitoring, group interview and individual interview study using a formative evaluation framework. SETTING/PARTICIPANTS: The partnership model was a collaboration between a large specialist palliative care hospice, a dementia charity and a Health Care Trust in the United Kingdom. Service documents were subjected to documentary review of monitoring activity and key indicators of service success. Group interviews and individual interviews took place with family carers (n = 12), health care professionals involved in delivering the service (n = 32) and senior professionals (n = 5) responsible for service commissioning in palliative or dementia care. RESULTS: One hundred people with dementia were referred to the service between May 2016 and December 2017. Thirty-eight of the 42 people who died, achieved their preferred place of care and died at home. Four themes were derived from the data ‘Impact of Dementia’, ‘Value of the Service’, ‘Information and Learning Needs’ and ‘Working in Partnership’. CONCLUSIONS: Positive outcomes resulted from this best practice model; achievement of preferred place of care and death at home, dual benefits of therapies for patients and families and partnership in cross working and learning between services. Replication of this model should be considered internationally
Changing teachers, changing Scotland?
Teacher professionalism and development are central to the study of education across the globe, and in particular, are central to concepts of educational reform and change. This article explores the centrality of teacher professionalism and development to the three substantive networks of the Applied Educational Research Scheme (AERS) in Scotland, examining how they feature within discussions about: school management and governance; schools and social capital; and teachers as learners. The article explores each of these contexts in turn concluding with consideration of how the work of the three AERS networks might help to understand and inform an agenda for change
