Mementos from Boots multisensory boxes: qualitative evaluation of an intervention for people with dementia: innovative practice

This qualitative study explored a multisensory (including olfactory) intervention for people with dementia. Six themed boxes (e.g. Childhood) containing items chosen from the Boots archive designed to encourage conversation were used in weekly group sessions. Session participants were people with dementia and care staff from a local care home, a trained facilitator and archivists from Boots UK. Semi-structured interviews explored participants’ experiences of the sessions. Interviews were analysed using Thematic Analysis. The three major themes Engagement (subthemes: Inclusiveness; Emotional involvement; Factors that supported engagement), What’s in the box (subthemes: Contents stimulate memories; Mystery, variety and age of items; Value of olfactory stimuli), and A conversation starter (subtheme: Opportunity for self-expression) reveal the success of the intervention and the value of olfactory stimuli. Multisensory boxes including olfactory stimulation can be an engaging intervention with scope to refine it for people with dementia and their carers in the wider community

Prevalence and Correlates of Overweight and Obesity among Preschool-Aged Children in San Luis Obispo County, 2006-2014

Background and Purpose: National prevalence of overweight and obesity (OW/OB) among children remains high; surveillance of OW/OB at state- and local-levels is needed. This study determines the prevalence and sociodemographic predictors of OW/OB among preschool-age children in San Luis Obispo (SLO) County. Methods: Cross-sectional convenience samples of Head Start, California State, and private preschools were surveyed in 2006 (n=482), 2009/10 (n=559), and 2014 (n=442). At all waves, preschool children aged 3-5 years were measured for height and weight using standardized stadiometer and digital scale protocols. In 2014, parents completed a demographics questionnaire. Results: Children assessed in 2009/10 and 2014 were more likely to be OW/OB than those assessed in 2006 (p=0.016). Unadjusted, bivariate odds ratios illustrated increased risk for OW/OB was associated with Hispanic ethnicity, residing in a lower income household, attending preschool in southern SLO County, and participation in a Head Start preschool. In the adjusted, multivariable model, increased risk for OW/OB was associated with attending preschool in SLO City and participation in a California State or Head Start preschool. Conclusion: OW/OB trends in SLO County are similar to national trends. Programs to continue to monitor and reduce socioeconomic disparity in OW/OB prevalence among young children are needed

Stationary solutions for the parity-even sector of the CPT-even and Lorentz-covariance-violating term of the standard model extension

In this work, we focus on some properties of the parity-even sector of the CPT-even electrodynamics of the standard model extension. We analyze how the six non-birefringent terms belonging to this sector modify the static and stationary classical solutions of the usual Maxwell theory. We observe that the parity-even terms do not couple the electric and magnetic sectors (at least in the stationary regime). The Green's method is used to obtain solutions for the field strengths E and B at first order in the Lorentz- covariance-violating parameters. Explicit solutions are attained for point-like and spatially extended sources, for which a dipolar expansion is achieved. Finally, it is presented an Earth-based experiment that can lead (in principle) to an upper bound on the anisotropic coefficients as stringent as $(\widetilde{\kappa}_{e-}) ^{ij}<2.9\times10^{-20}.$Comment: 8 pages, revtex style, revised published version, to appear in EPJC (2009

CPT and Lorentz tests with muons

Precision experiments with muons are sensitive to Planck-scale CPT and Lorentz violation that is undetectable in other tests. Existing data on the muonium ground-state hyperfine structure and on the muon anomalous magnetic moment could be analyzed to provide dimensionless figures of merit for CPT and Lorentz violation at the levels of $4\times 10^{-21}$ and $10^{-23}$.Comment: 4 pages, accepted for publication in Physical Review Letter

Data Generated during the 2018 LAPSE-RATE Campaign: An Introduction and Overview

Unmanned aircraft systems (UASs) offer innovative capabilities for providing new perspectives on the atmosphere, and therefore atmospheric scientists are rapidly expanding their use, particularly for studying the planetary boundary layer. In support of this expansion, from 14 to 20 July 2018 the International Society for Atmospheric Research using Remotely piloted Aircraft (ISARRA) hosted a community flight week, dubbed the Lower Atmospheric Profiling Studies at Elevation – a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE; de Boer et al., 2020a). This field campaign spanned a 1-week deployment to Colorado\u27s San Luis Valley, involving over 100 students, scientists, engineers, pilots, and outreach coordinators. These groups conducted intensive field operations using unmanned aircraft and ground-based assets to develop comprehensive datasets spanning a variety of scientific objectives, including a total of nearly 1300 research flights totaling over 250 flight hours. This article introduces this campaign and lays the groundwork for a special issue on the LAPSE-RATE project. The remainder of the special issue provides detailed overviews of the datasets collected and the platforms used to collect them. All of the datasets covered by this special issue have been uploaded to a LAPSE-RATE community set up at the Zenodo data archive (https://zenodo.org/communities/lapse-rate/, last access: 3 December 2020)

Surface and Temporal Biosignatures

Recent discoveries of potentially habitable exoplanets have ignited the prospect of spectroscopic investigations of exoplanet surfaces and atmospheres for signs of life. This chapter provides an overview of potential surface and temporal exoplanet biosignatures, reviewing Earth analogues and proposed applications based on observations and models. The vegetation red-edge (VRE) remains the most well-studied surface biosignature. Extensions of the VRE, spectral "edges" produced in part by photosynthetic or nonphotosynthetic pigments, may likewise present potential evidence of life. Polarization signatures have the capacity to discriminate between biotic and abiotic "edge" features in the face of false positives from band-gap generating material. Temporal biosignatures -- modulations in measurable quantities such as gas abundances (e.g., CO2), surface features, or emission of light (e.g., fluorescence, bioluminescence) that can be directly linked to the actions of a biosphere -- are in general less well studied than surface or gaseous biosignatures. However, remote observations of Earth's biosphere nonetheless provide proofs of concept for these techniques and are reviewed here. Surface and temporal biosignatures provide complementary information to gaseous biosignatures, and while likely more challenging to observe, would contribute information inaccessible from study of the time-averaged atmospheric composition alone.Comment: 26 pages, 9 figures, review to appear in Handbook of Exoplanets.

Towards drought impact-based forecasting in a multi-hazard context

The lives and livelihoods of people around the world are increasingly threatened by climate-related risks as climate change increases the frequency and severity of high-impact weather. In turn, the risk of multiple hazards occurring simultaneously grows and compound impacts become more likely. The World Meteorological Organization (WMO) proposed the use of multi-hazard impact-based forecasting (IbF) to better anticipate and reduce the impacts of concurrent hazards, but as yet, there are few operational examples in the humanitarian sector. Drought is particularly susceptible to multi-hazard influences. However, challenges encountered in the development of drought IbF systems – including poor understanding of compound impacts and specific hazard-focused mandates – raise important questions for the feasibility of multi-hazard IbF as envisioned by the WMO. With these challenges in mind, we propose an interim approach in which real-time assessment of dynamic vulnerability provides a context for drought-based IbF. The incorporation of dynamic vulnerability indicators account for the local effects of non-drought hazards, whilst the use of a drought-based system facilitates effective intervention. The proposed approach will improve our understanding of compound events, enhance adoption of IbF in the humanitarian sector, and better mitigate the impacts of concurrent hazards
