Enhanced Living Environments

This open access book was prepared as a Final Publication of the COST Action IC1303 “Algorithms, Architectures and Platforms for Enhanced Living Environments (AAPELE)”. The concept of Enhanced Living Environments (ELE) refers to the area of Ambient Assisted Living (AAL) that is more related with Information and Communication Technologies (ICT). Effective ELE solutions require appropriate ICT algorithms, architectures, platforms, and systems, having in view the advance of science and technology in this area and the development of new and innovative solutions that can provide improvements in the quality of life for people in their homes and can reduce the financial burden on the budgets of the healthcare providers. The aim of this book is to become a state-of-the-art reference, discussing progress made, as well as prompting future directions on theories, practices, standards, and strategies related to the ELE area. The book contains 12 chapters and can serve as a valuable reference for undergraduate students, post-graduate students, educators, faculty members, researchers, engineers, medical doctors, healthcare organizations, insurance companies, and research strategists working in this area

Design Opportunities for Assistive and Social Technologies Situated in Space

Computers are increasingly integrated into daily environments. Human interactions with computers become inseparable from interacting with physical spaces. I take a qualitative research approach to consider space as an integral part of understanding people, leading to design opportunities for technologies situated in space. My thesis presents the design opportunities for blind assistive technology to support exploratory navigation and physically-grounded social technology for remote connections. Studying space gives insights into how users and technologies situated in space interact with one another, how users perceive the physical space, and what behavioral patterns users display around the space while using technology. The insights contribute to constructing design implications from an underexplored creative angle and shed light on how spatial scenarios dynamically change preferences and opportunities in the design of future technologies

The effect of bright light on sleep in nursing home patients with dementia

Background: Up to 70% of nursing home patients with dementia suffer from disrupted sleep, often characterized by multiple awakenings at night and excessive daytime sleep. Sleep disruption may have negative effects on the cognition, mood, behaviour, and well-being of nursing home patients, while also representing a challenge for nursing home staff. However, few sleep scales are developed and validated specifically for the nursing home setting. Sleep problems among nursing home patients are frequently treated by medications, which are associated with severe side effects, including daytime sleepiness, and an increased risk of falls. Thus, there is a need for non-pharmacological interventions to improve sleep in this population. Bright light treatment (BLT) may represent such an intervention, providing increased light exposure aiming to impact sleep, circadian rhythmicity, mood, and/or behaviour. Light is the most important zeitgeber to the circadian system, and consequently has a significant impact on sleep-wake behaviour. Unfortunately, studies have reported low indoor light levels in nursing homes, which in combination with dementia-related neuropathology and age-related reductions in light sensitivity, are likely to contribute to sleep problems in this population. The aim of this thesis was to investigate whether increasing daytime light exposure, by means of BLT, can improve sleep in nursing home patients with dementia, and also to address methodological challenges in this field of research. Methods: Paper 1 is a systematic review of the literature, focusing on the methodological features of the included studies, in addition to their findings. Paper 2 and 3 are based on data from the DEM.LIGHT trial; a cluster-randomized placebo-controlled trial conducted in Norwegian nursing homes, including 69 patients. The intervention comprised a diurnal cycle of ambient light with a maximum of 1,000 lux and 6,000 Kelvin (K) from 10:00-15:00, administered using light emitting diode (LED) light. Before and after this interval, the light levels gradually increased/decreased in lux and K. In the placebo condition, standard light levels were maintained at 150-300 lux and approximately 3,000 K throughout the day. The intervention and placebo lights were installed in the common rooms of the included nursing home units. Outcomes were measured at baseline and at follow-up at week 8, 16, and 24. Paper 2 was a validation study of a proxy-rated sleep scale, using the baseline data from the DEM. LIGHT trial. Actigraphy was used as the reference standard. Paper 3 reported on the sleep outcomes of the trial, which were the primary outcomes. Results: Paper 1 found that there are promising, though inconsistent, results regarding the effect of BLT on sleep and circadian rhythmicity in dementia. Large heterogeneity in terms of interventions, study designs, population characteristics, and outcome measurement tools may explain some of the inconsistencies of results across studies. Paper 2 showed that the proxy-rated Sleep Disorder Inventory (SDI) had satisfactory internal consistency and convergent validity. Using actigraphy as the reference standard, the SDI was termed clinically useful, and we suggested a cut-off score of five or more as defining disrupted sleep in nursing home patients with dementia. These results should be interpreted keeping in mind that actigraphy have some important weaknesses, such as underestimating wake time. Paper 3 evaluated the effects of the BLT on sleep and found an improvement in sleep according to the SDI scores in the intervention group, as compared to the control group, from baseline to week 16 and baseline to week 24. There was no effect in terms of sleep measured by actigraphy. Conclusion: In summary, this thesis found that the evidence for an effect of BLT on sleep in nursing home patients with dementia is promising, but equivocal. Importantly, the research field faces some important methodological challenges, such as accurately measuring sleep. The SDI may represent a valid tool to measure sleep in the nursing home setting, which may be used both by researchers and by practitioners. Although the results of this thesis are not conclusive regarding the effect of BLT on sleep in nursing home patients with dementia, it may represent a step forward in understanding the potential value of BLT in this population, and may lay the ground for further investigation. The lack of an improvement on the SDI at week 8 indicates that the effect of BLT may take a long time to manifest in this population.Doktorgradsavhandlin

The role of social and endocrinological context in regulating life history transitions among reproductive phenotypes in in the bluebanded goby, Lythrypnus dalli

During the lifetime of an organism, key events are orchestrated by a confluence of environmental, social, and physiological factors to promote reproductive success. Steroid hormones are critical regulators of fundamental aspects of reproductive life history, including gametogenesis, secondary sexual characteristics, sexual behavior, territory establishment and defense, and parenting. The steroid hormones investigated herein (testosterone (T), 11-ketotestosterone (KT), 17b-estradiol (E2) and cortisol) are linked through steroidogenic conversion pathways. This dissertation utilized an integrative approach to investigate the neuroendocrine and social contexts that regulate transitions among phenotypes in a bi-directionally hermaphroditic haremic fish, Lythrypnus dalli. Conventional sex roles are reversed, such that only males provide nest care, females exhibit intra-sexual competition and male reproductive success is associated with female courtship solicitation. Females living in stable social groups maintain dramatic differences in status, morphology, and tissue T, KT, E2, and cortisol. Parasitic male morphs, mini males, do not defend territories and have morph-typical water-borne and tissue profiles of T, E2, and KT. Two life history transitions, socially induced sex change and male parenting, are associated with increase in rates of behavior and KT levels. The regulation of these life history transitions by KT was investigated via two types of endocrine manipulations. Coupling systemic KT implants with a social context permissive to sex change caused rapid, but transient effects on agonistic behavior in dominant females, and secondary effects on subordinates during a period of social instability. Despite elevated brain and systemic KT 5 d after implant, overall rates of aggressive behavior remained unaffected, demonstrating a key role for context in regulating steroid associated changes in behavior. Intracerebroventricular inhibition of the enzyme 11b-hydroxysteroid dehydrogenase, reduced KT, elevated cortisol, and reduced male parenting behavior. 11-Ketotestosterone rapidly rescued parenting when administered along with the inhibitor, while cortisol had no effects on parenting. During reduced male nest attendance caused by KT inhibition, dominant, but not subordinate females, exhibited transient parenting and elevated brain KT. Taken together, rapid and/or local modulation of steroids allows for context-specific regulation of dynamic changes in behavior in an environment that requires an organism to successfully coordinate multiple activities to enhance fitness

All in the Family: Exploring Design Personas of Systems for Remote Communication with Preschoolers

Although there have been recent advances in remote communication technologies that foster connectedness and intimacy over a distance, systems designed for communicating with preliterate preschoolers—a desired use case—are not yet prevalent, nor are there clear guidelines for their design. We conducted a mixed-methods study to characterize the current practices, goals, and needs of people who wish to use remote communication systems with young children. We present quantitative and qualitative findings on the motivations for communicating, the habits, activities, and patterns that have been established, and the barriers and concerns faced. We synthesized these findings into four design personas that describe the desired functionality and requirements of systems to support remote communication with preschoolers. For each persona, we systematically evaluated 60 research-based systems based on the extent to which each persona’s requirements were covered, demonstrating that none of the personas were greatly satisfied with the available tools
