There are currently about 6 million – mainly older – people with dementia in the European Union. With ageing, a number of sensory changes occur. Dementia syndrome exacerbates the effects of these sensory changes and alters perception of stimuli. People with dementia have an altered sensitivity for indoor environmental conditions, which can induce problematic behaviour with burdensome symptoms to both the person with dementia and the family carer. This paper, based on literature review, provides an overview of the indoor environmental parameters, as well as the integrated design and implementation of relevant building systems. The overview is presented in relation to the intrinsic ageing of senses, the responses of older people with dementia and the impact on other relevant stakeholders through the combined use of the International Classification of Functioning, Disability and Health, and the Model of Integrated Building Design. Results are presented as indicators of the basic value, functional value and economic value, as well as a synthesis of building-related solutions. Results can help designers and building services engineers to create optimal environmental conditions inside the living environments for people with dementia, and can be used to raise awareness among health care professionals about of the influence of the indoor environment on behaviour of the person with dementia. 相似文献

A decline in the cognitive ability of mental rotation causes a poor sense of spatial direction and environmental cognitive capacity. Currently, training tasks for the elderly thus affected are still presented in 2D form. However, clinical research indicates that this strategy generates a cognitive load that reduces the interest of the trainees and diminishes the effects of training. In contrast, augmented reality (AR) is a rising solution that effectively reduces cognitive load, improves the sense of spatial direction of the elderly, and helps increase interest in training. We recruited 28 elderly (age ≥ 65 years) for this study. Fourteen were randomly assigned to an active Intervention group and were given AR-based 3D hologram (AR-3DH) mental rotation training, and 14 were assigned to a group that used the traditional 2D model. Both groups took ABA-designed pre-and post-tests that required inferring the rotating shapes' states from standard mental rotation tasks. Change scores for the two groups were compared using error rates and reaction times as covariates. After six-week of training, the mental rotation ability of the Intervention group improved through the use of AR-3DH training system during the intervention phase. The practical and developmental implications of the findings are discussed. 相似文献

Self-regulation in driving has primarily been studied as a precursor to driving cessation in older people, who minimise driving risk and compensate for physical and cognitive decline by avoiding driving in challenging circumstances, e.g. poor weather conditions, in the dark and at busy times. This research explores whether other demographic groups of drivers adopt self-regulatory behaviours and examines the effects of affective and instrumental attitudes on self-regulation across the lifespan. Quantitative data were collected from 395 drivers. Women were significantly more likely than men to engage in self-regulation, and to be negatively influenced by their emotions (affective attitude). A quadratic effect of age on self-regulation was determined such that younger and older drivers reported higher scores for self-regulation than middle-years’ drivers. However, this effect was affected by experience such that when experience was controlled for, self-regulation increased with age. Nevertheless, anxious driving style and negative affective attitude were independent predictors of self-regulation behaviours. Results suggest that self-regulation behaviours are present across the driving lifespan and may occur as a result of driving anxiety or low confidence rather than as an effect of ageing. 相似文献

This article evaluates the propensity of firms to apply for R&D public grants, their capacity for obtaining subsides and how these relate to the firm age. This analysis is particularly relevant in understanding why young firms may be more or less successful in their application for public subsidies. Using data from an extensive database of 19,236 firms in Catalonia, we estimate a maximum likelihood probit model with sample selection. Our results show that firm age does not exert a significant direct impact on the application propensity in R&D public call, but younger firms tend to show a larger propensity to receive an R&D subsidy. They also show that firm age exerts a moderating role through different internal resources. They highlight the need to design R&D public policies that explicitly favour applications by young firms to help overcome their obstacles to innovation. 相似文献
