- Demographic changes and a predicted shortage of nursing staff are progressively putting pressure on the healthcare system. Care robots may represent one part of a possible solution to this problem as they can assist care work. However, large parts of the population are reportedly skeptical about robotics in care, and field studies are difficult to conduct due to the low prevalence of real robotics in the field. Therefore, we follow an experimental approach pertaining to the question of individual decision-making. In this regard, we analyze the aspects that influence the individual's choice between a care robot and a human caregiver for assistance in their daily life. Our economic experiment is conducted in a virtual laboratory to examine specifically how quality uncertainty of care affects individual's decisions for and against robotic care. In the experiment, 162 participants fully completed the experiment in which they were asked to repeatedly choose between a human caregiver and a care robot. Our results reveal that, overall, the care robot is chosen more often than a human caregiver. At the same time, the quality uncertainty of care linked to a human caregiver barely affected the choice of participants. On the other hand, a participant's health status and their attitude toward direct interactions with care robots did partially affect their choice. Additionally, we explored causes for indecisiveness and its effect on the choice. Here, we found indecisive participants tending to choose a human caregiver more often.

- This paper explores Finnish, German and Swedish older adults’ perceptions of a future welfare service with increased use of welfare technologies, specifically care robots. The issues are the rapid digitalization and development of health and welfare technology, which presently is mainly technology driven (not need or user driven), and the demographic challenge. The aim of the study was to explore older adults’ perception of the future use of welfare technology or care robots. A qualitative approach with focus group discussions was employed, followed by thematic analysis. The results are presented in four overall themes: the impact on daily life for older adults and professional caregivers, codes of practice and terms of use, dissemination of information and knowledge, and conditions for successful implementation. There were significant differences in the informants’ attitudes toward and knowledge about care robots. However, the informants’ attitudes appeared to change during the focus groups and in general, became more positive. Authentic needs, which care robots could support, refer to independence, safety and security, and the ability to manage or ease daily life or working life. The results suggest that older adults, after receiving relevant information, were open to the idea of being supported by care robots in their daily lives.

- Physical activity (PA) has beneficial effects on older age physical functioning, but longitudinal studies with follow-ups extending up to decades are few. We investigated the association between leisure-time PA (LTPA) and occupational PA (OPA) from early to late adulthood in relation to later life performance-based physical functioning.Methods:The study involved 1260 people aged 60 to 79 years who took part in assessments of physical functioning (Short Physical Performance Battery [SPPB] test, 10-m maximal walking test, and grip strength test). Participants’ data on earlier life LTPA/OPA (age range 25 to 74 years) were received from the previous studies (average follow-up 13.4 years). Logistic, linear, and censored regression models were used to assess the associations between LTPA/OPA earlier in life and subsequent physical functioning.Results:A high level of LTPA earlier in life was associated with a lower risk of having difficulties on the SPPB test (odds ratio [OR]: 0.37; 95% confidence interval [CI], 0.24–0.58) and especially on the chair rise test (OR: 0.42; 95% CI, 0.27–0.64) in old age. Heavy manual work predicted difficulties on SPPB (OR: 1.91; 95% CI, 1.22–2.98) and the chair rise test (OR: 1.75; 95% CI, 1.14–2.69) and poorer walking speed (β = .10, P = .005).Conclusions:This study highlights the importance of LTPA on later life functioning, but also indicates the inverse effects that may be caused by heavy manual work.

- Lakes are generally supersaturated in carbon dioxide (CO2) and emitters of CO2 to the atmosphere. However, estimates of CO2 flux ((Formula presented.)) from lakes are seldom based on direct flux measurements and usually do not account for nighttime emissions, yielding risk of biased assessments. Here, we present direct (Formula presented.) measurements from automated floating chambers collected every 2–3 hr and spanning 115 24 hr periods in three boreal lakes during summer stratification and before and after autumn mixing in the most eutrophic lake of these. We observed 40%–67% higher mean (Formula presented.) in daytime during periods of surface water CO2 supersaturation in all lakes. Day-night differences in wind speed were correlated with the day-night (Formula presented.) differences in the two larger lakes, but in the smallest and most wind-sheltered lake peaks of (Formula presented.) coincided with low-winds at night. During stratification in the eutrophic lake, CO2 was near equilibrium and diel variability of (Formula presented.) insignificant, but after autumn mixing (Formula presented.) was high with distinct diel variability making this lake a net CO2 source on an annual basis. We found that extrapolating daytime measurements to 24 hr periods overestimated (Formula presented.) by up to 30%, whereas extrapolating measurements from the stratified period to annual rates in the eutrophic lake underestimated (Formula presented.) by 86%. This shows the importance of accounting for diel and seasonal variability in lake CO2 emission estimates.
