Experiencing visual impairment in a lifetime home: an interpretative phenomenological inquiry

Lifetime home standards (LTHS) are a set of standards aimed at making homes more accessible. Previous research, however, indicates that LTHS do not adequately meet the needs of those with sensory impairments. Now, with visual impairment set to increase globally and acknowledging the recognised link between quality of dwelling and wellbeing, this article aims to examine the experiences of visually impaired people living in lifetime homes. The objectives are to investigate existing lifetime homes and to identify whether LTHS meet occupants’ needs. Qualitative semi-structured interviews were carried out with six visually impaired people living in homes designed to LTHS in Northern Ireland. Collected data was analysed using interpretative phenomenological analysis identifying three super-ordinate themes: (1) living with visual impairment; (2) design considerations and (3) coping strategies. A core theme of balance between psychological and physical needs emerged through interconnection of super-ordinate themes. Although there are benefits to living in lifetime homes, negative aspects are also apparent with occupants employing several coping strategies to overcome difficulties. Whilst residents experience negative emotions following visual impairment diagnoses, results suggest that occupants still regard their homes as key places of security and comfort in addition to then highlighting the need for greater consideration of specific individual needs within general guidelines

Multi-scale synthesis of historical fire regimes along the south-central US prairie-forest border

dendrochronology; drought; humans; oak; prairie; woodlandBackground: Along the prairie-forest border in the south-central USA exists one of the most extensive areas of uncut forest in the nation ([greater than]323 750 hectares), providing unique potential for developing multi-century records of environmental changes through dendrochronological analyses. Twentieth century changes in vegetation, increased prescribed fire management, and recent years of elevated wildfire activity have increased interest in understanding the region's long-term fire regime characteristics. To address this need, we analyzed and compared fire intervals, seasonality, severity, and extent based on fire-scar history datasets from three new and ten existing study sites. Results: At the study sites, mean fire intervals ranged from 3 to 10 years prior to Euro-American settlement and generally became more frequent after. The majority of fires occurred in the dormant season and resulted in low percentages of trees scarred. Coinciding with Euro-American settlement (EAS), fire frequencies appear to have varied by geography. At the regional scale, fire regimes have trended towards decreased fire severity and slightly decreased fire intervals over the past 300 years. Further, fires appear to have increased in extent from circa 1770 to the mid to late 1800s, after which it began to decline, circa 1920. Conclusions: Although frequent, descriptions of fire regimes since the eighteenth century should be characterized as time-dependent and spatially variable, likely depending on local socio-ecological influences. Similar influences may explain fire frequency increases following EAS, while fire severity trended lower. c2019, The Author(s).Includes bibliographical references

Structural Characteristics of Pennisetum Americanum (Pearl Millet) Using Scanning Electron and Fluorescence Microscopy

Fluorescence bright field and scanning electron microscopy were used to characterize the structure of selected mature pearl millet caryopses from the World Germplasm Collection. Kernel shape (globose, lanceolate, obovate and hexagonal). kernel endosperm color (while. yellow and grey) and external appearance (color) of the samples were documented for 96 varieties. Color of the pearl millet kernel was due to the combined effects of pigmentation in the pericarp. aleurone and endosperm. as well as the pericarp thickness. White kernels had few pigmented areas. yellow kernels had pigments primarily in the epicarp and endosperm. and brown kernels had pigments in the epicarp. aleurone and endosperm. The majority of white, yellow and brown kernels had a thick pericarp. Purple kernels also had pigments in the epicarp, aleurone and endosperm, but had a thin pericarp. Grey kernels had pigments in the aleurone and endosperm. and had a thin pericarp. The periicarp was different from that found in sorghum in that the epicarp cells could be large, round, multilayered and full of pigments, or flat. single-layered and empty. The seed coat and a leurone layer were similar to those found in sorghum. Phytin and nicotinic acid were present in the germ. B-D-glucans were present in the cell walls in the endosperm

Low fruit and vegetable consumption is associated with low knowledge of the details of the 5-a-day fruit and vegetable message in the UK: findings from two cross-sectional questionnaire studies.

BACKGROUND: This project aimed to understand the details of the 5-a-day fruit and vegetable (FV) message (which foods are included, portion sizes, the need for variety, reasons for consumption) least known by UK consumers, and most associated with low FV consumption. METHODS: Study 1 assessed FV consumption, knowledge of the details of the message, and relationships between these, using a short questionnaire administered face-to-face to an opportunity sample of one large UK city. Study 2 assessed the same variables using a comprehensive postal questionnaire administered across the UK to a representative population sample. RESULTS: Five hundred and seven respondents completed Study 1 and 247 respondents completed Study 2. The majority of individuals in both studies were aware of the 5-a-day message and could recount this correctly. In both studies, however, knowledge of the details of the message was low, and lower knowledge was associated with lower FV consumption. Respondents had lowest knowledge of the details of the message related to portion sizes and the need for variety. However, FV consumption was not independently associated with knowledge of any one aspect of the message. CONCLUSIONS: These findings suggest that, although most of the UK population sampled were aware of the 5-a-day FV message and could recount this correctly, details of the 5-a-day FV message were not well known, and that FV consumption was related to this knowledge. These findings suggest that strategies to increase FV consumption will benefit from increasing UK consumers' knowledge of the details of the 5-a-day FV message
