Although there is a growing literature on the use of telepresence robots in institutional dementia care settings, limited research focused on the perspectives of frontline staff members who deliver dementia care. Our objective was to understand staff perspectives on using telepresence robots to support residents with dementia and their families. Guided by the Consolidated Framework for Implementation Research, we conducted four focus groups and 11 semi-structured interviews across four long-term care (LTC) homes and one hospital in Canada. We included 22 interdisciplinary staff members (e.g., registered nurses, social workers, occupational therapists, recreational therapists) to understand their experiences with telepresence robots. Thematic analysis identified three key themes: 1) Staff Training and Support; 2) Robot Features; 3) Environmental dynamics for Implementation. Our results underscore the imperative of structural support at micro-, meso- and macro-levels for staff in dementia care settings to effectively implement technology. This study contributes to future research and practice by elucidating factors facilitating staff involvement in technology research, integrating staff voices into technology implementation planning, and devising strategies to provide structural support to staff, care teams, and care homes.

Abstract: In situ laser ablation ICP-MS U–Pb dating of metamorphic rutile from granulite facies metapelitic rocks of the Archaean Pikwitonei granulite domain (Manitoba, Canada) provides constraints on Pb diffusion and characterizes the closure behavior of rutile. The analysis of transects of 35-μm spots across 15 rutile grains having a size of 120 to 280μm yielded concordant ages with core ages of ca. 2450Ma and core-to-rim younging towards 2280Ma. Age profiles indicate that volume diffusion of Pb occurs in rutile implying that the ages represent cooling ages. To investigate the closure behavior of Pb in rutile closure temperature profiles (T c(x)) were constructed based on different models combined with experimentally-determined diffusion parameters. The classical T c(x) model of Dodson (1986; Mat. Sci. Forum 7, 145–154) indicates a rapid decrease of T c in the rims of grains, providing unrealistic estimates for the cooling rate when combined with U–Pb ages. A new T c(x) model was constructed based on the analyzed age profiles that are described by an error function. This model shows a more steady decrease in T c throughout the grain from ca. 640°C in the core (depending on grain size) to a rim intercept (T c,rim) of 490°C (±7, 2σ), which is interpreted to be the extrapolated theoretical absolute temperature of insignificant Pb diffusion in rutile. The new model provides a better description of the relation between age and T c for the analyzed grains. However, both T c(x) models demonstrate that even in small grains the variations of T c can be significant making it impossible to derive one representative T c for Pb in rutile. The error function-based T c(x) model allows the determination of cooling rates, which show a decrease over time from ca. 2.2 to 0.4°C/Ma agreeing well with previous estimates for the Pikwitonei granulite domain. This consistency supports the validity of our model and indicates that cooling rates can be estimated from single grains by LA-ICP-MS U–Pb dating of rutile providing constraints on the cooling history of a metamorphic terrane. The slow cooling rates imply that exhumation was slow (<0.1mm/yr) and was controlled by surface erosion. [Copyright &y& Elsevier]

The Canadian Organization of Medical Physicists (COMP), in close partnership with the Canadian Partnership for Quality Radiotherapy (CPQR), has developed a series of Technical Quality Control (TQC) guidelines for radiation treatment equipment. These guidelines outline the performance objectives that equipment should meet in order to ensure an acceptable level of radiation treatment quality. The TQC guidelines have been rigorously reviewed and field tested in a variety of Canadian radiation treatment facilities. The development process enables rapid review and update to keep the guidelines current with changes in technology (the most updated version of this guideline can be found on the CPQR website). This particular TQC details recommended quality control testing for Gamma Knife radiosurgery., (© 2018 The Authors.
