Smart technology for healthcare: Exploring the antecedents of adoption intention of healthcare wearable technology

© The Author(s), 2019. Technological advancement and personalized health information has led to an increase in people using and responding to wearable technology in the last decade. These changes are often perceived to be beneficial, providing greater information and insights about health for users, organizations and healthcare and government. However, to date, understanding the antecedents of its adoption is limited. Seeking to address this gap, this cross-sectional study examined what factors influence users’ adoption intention of healthcare wearable technology. We used self-administrated online survey to explore adoption intentions of healthcare wearable devices in 171 adults residing in Hong Kong. We analyzed the data by Partial least squares – structural equation modelling (PLS-SEM). The results reveal that perceived convenience and perceived irreplaceability are key predictors of perceived useful ness, which in turn strengthens users’ adoption intention. Additionally, the results also reveal that health belief is one of the key predictors of adoption intention. This paper contributes to the extant literature by providing understanding of how to strengthen users’ intention to adopt healthcare wearable technology. This includes the strengthening of perceived convenience and perceived irreplaceability to enhance the perceived usefulness, incorporating the extensive communication in the area of healthcare messages, which is useful in strengthening consumers’ adoption intention in healthcare wearable technology

However, no unambiguous photochemical products have been detected in exoplanet atmospheres so far. Recent observations from the JWST Transiting Exoplanet Community Early Release Science Program2,3 found a spectral absorption feature at 4.05 μm arising from sulfur dioxide (SO2) in the atmosphere of WASP-39b. WASP-39b is a 1.27-Jupiter-radii, Saturn-mass (0.28 MJ) gas giant exoplanet orbiting a Sun-like star with an equilibrium temperature of around 1,100 K (ref. 4). The most plausible way of generating SO2 in such an atmosphere is through photochemical processes5,6. Here we show that the SO2 distribution computed by a suite of photochemical models robustly explains the 4.05-μm spectral feature identified by JWST transmission observations7 with NIRSpec PRISM (2.7σ)8 and G395H (4.5σ)9. SO2 is produced by successive oxidation of sulfur radicals freed when hydrogen sulfide (H2S) is destroyed. The sensitivity of the SO2 feature to the enrichment of the atmosphere by heavy elements (metallicity) suggests that it can be used as a tracer of atmospheric properties, with WASP-39b exhibiting an inferred metallicity of about 10× solar. We further point out that SO2 also shows observable features at ultraviolet and thermal infrared wavelengths not available from the existing observations.Publisher PDFPeer reviewe

Vluchthaven Wijdenes: Verzandingsprobleem in de vluchthaven

In opdracht van het Recreatieschap Westfriesland werd een onderzoek gestart naar het verzandingsprobleem in de vluchthaven Wijdenes. De vluchthaven kampte jarenlang met verzandingsproblemen en er zijn diverse onderzoeken en aanpassingen uitgevoerd, maar het probleem is nog steeds niet verholpen. Door de verscherpte wetgeving in 2008, zijn de kosten voor het behandelen van baggerspecie toegenomen. Hierdoor is het financieel niet meer rendabel voor de havenbeheerder om de haven op diepte te houden. Bij een bezoek ter plaatse bleek dat de zuidelijke golfbreker verzakt was. De opbouw van de golfbreker bestaat uit een geotube, een kunststoffilter en breukstenen. Door de verzakking van de golfbreker vindt nu golfoverslag met sediment plaats dat zorgt voor verzanding achter de zuidelijke golfbreker. Golfoverslag vindt meestal plaats in de zomer, omdat de waterstand in onze situatie de maatgevende factor is. Naast golfoverslag is de golfbreker ook sedimentdoorlatend geworden bij windopzet. Dit gebeurt wanneer het waterniveau de bovenkant van de geotube heeft bereikt. Ook de vorm van de zuidelijke golfbreker zorgt voor verzandingsproblemen. De golfbreker staat bijna haaks op de kustlijn en zorgt ervoor dat het water achter de golfbreker kalmer wordt. Door het kalmere water kan het sediment bezinken en vervolgens naar de haven worden verplaats. Als laatste is de noordelijke golfbreker te kort, hierdoor kan sediment uit het noorden de golfbreker passeren. Omdat de zuidelijke golfbreker langer is dan de noordelijke golfbreker, wordt het sediment opgevangen door de zuidelijke golfbreker en vindt er verzanding plaats in de vluchthaven. Om verzanding van de vluchthaven te beperken, zijn drie alternatieven uitgewerkt. Het verzakte golfbreker herstellen; de vorm van de zuidelijke golfbreker aanpassen en als laatst worden beide golfbrekers aangepast. Een kostenanalyse zou uitgevoerd moeten worden voor de diverse alternatieven, om de financiële haalbaarheid vast te stellen. Met behulp van een Multi- Criteria- Evaluatie ontstaat er een overzicht van de sterke en zwakke punten van elk alternatief. Het vaststellen van de toekomstvisie van de vluchthaven is bepalend voor de keuze van de alternatieven.Hydraulic EngineeringCivil Engineering and Geoscience

Interfaces in metamict titanite: the macroscopic mechanical properties after stepwise annealing

Elastic material properties of metamict titanite (sample E2312) during thermally induced stepwise recrystallization are measured using nanoindentation. Changes of the elastic modulus (E) and the hardness (H) are related to increasing long-range order and vanishing amorphous interface areas. Metamict titanite shows H and E values close to titanite glass. H decreases on annealing until ca. 950 K to 9.08 GPa and increases at higher temperatures, while E increases continuously on annealing up to ca. 168.4 GPa at 1220 K. Crystalline titanite from Rauris shows strong anisotropy and H and E values are clearly larger than those of E2312
