Five Degrees of Happiness: Effective Smiley Face Likert Scales for Evaluating with Children

This paper focuses on achieving optimal responses through supporting children’s judgements, using Smiley Face Likert scales as a rating scale for quantitative questions in evaluations. It highlights the need to provide appropriate methods for children to communicate judgements, highlighting that the traditional Smiley Face Likert scale does not provide an appropriate method. The paper outlines a range of studies, identifying that to achieve differentiated data and full use of rating scales by children that faces with positive emotions should be used within Smiley Face Likert scales. The proposed rating method, the Five Degrees of Happiness Smiley Face Likert scale, was used in a large-scale summative evaluation of a Serious Game resulting in variance within and between children, with all points of the scale used

Engaging Children in Interactive Application Evaluation

nteractive applications designed specifically for children offer great potential for education and play. However, to ascertain that the aims of applications are achieved, child-centred evaluations must be conducted. The design of any evaluation with children requires significant consideration of potential problems with comprehension, cognitive ability, response biases and study attrition. Multidisciplinary R&D project evaluation requirements are often extensive, requiring an all-encompassing and prolonged evaluation design. Discontinuity between the highly engaging interaction experience and themultitude of measures that form the evaluation poses a major issue for the evaluation of interactive applications. In response, we have developed Transmedia Evaluation, a method that aims to maintain engagement throughout the evaluation process. In this paper, the Transmedia Evaluation process is explained and applied to evaluate a learning application for children, MIXER (Moderating Interactions for Cross Cultural Empathic Relationships). Children aged 9-11 (N = 117) used the MIXER application and completed an evaluation battery including pre- and posttest questionnaires, immediate learning assessment and qualitative evaluation. Using Transmedia Evaluation to develop the MIXER evaluation resulted in complete data-sets (100%) for quantitative data (by self-regulated completion) along with rich, high quality qualitative responses. Transmedia Evaluation transformed the evaluation, with children fully engaging in and enjoying their experience. Engaging Children in Interactive Application Evaluation (PDF Download Available).

Rotator cuff related shoulder pain. Describing home exercise adherence and the use of behavior change interventions to promote home exercise adherence:a systematic review of randomized controlled trials

Background: A home exercise program (HEP) is integral in the management of rotator cuff related shoulder pain (RCRSP). There are many methods of measuring HEP adherence and many possible interventions to promote HEP adherence. Understanding the adherence rates to HEP and the strategies used to promote HEP adherence is important in order to interpret the existing evidence for the use of HEP in the management of RCRSP. Objectives: To report and synthesize home exercise adherence and strategies to promote home exercise adherence in order to understand the limitations of the current evidence base and make recommendations for clinical practice and future research investigating HEPs in the management of RCRSP. Methods: An electronic search of EMBASE, MEDLINE, PubMed, CINAHL, AMED, and CENTRAL was undertaken. Methodological quality was assessed using the Cochrane RoB 2.0, and BC techniques were coded in accordance with the BC technique taxonomy (version 1). Results: Seventeen RCTs were retrieved. Forty-seven percent described a formal method of measuring HEP adherence and 29% described adherence rates. The included studies described between three and seventeen BC techniques and the mean number of BC techniques per study was 5.8. Twelve percent of the studies described offering patients an explanation of how the exercise program might help their symptoms resolve. Conclusions: Poor reporting of adherence and the underutilisation of BC interventions to promote HEP adherence was prevalent. Recommendations for clinicians and researchers include more widespread use and definitive reporting of BC techniques to promote adherence, and the use of objective, patient self-reported, and clinician-assessed measures of adherence when prescribing HEPs. © 2021 The Author(s).

An unusual reservoir of water emission in the VV CrA A protoplanetary disk

We present an analysis of an unusual pattern of water vapor emission from the $\sim$2 Myr-old low-mass binary system VV CrA, as observed in infrared spectra obtained with VLT-CRIRES, VLT-VISIR, and Spitzer-IRS. Each component of the binary shows emission from water vapor in both the L ($\sim3\,\mu$m) and N ($\sim 12\,\mu$m) bands. The N-band and Spitzer spectra are similar to those previously observed from young stars with disks, and are consistent with emission from an extended protoplanetary disk. Conversely, the CRIRES L-band data of VV CrA A show an unusual spectrum, which requires the presence of a water reservoir with high temperature ($T\gtrsim1500$ K), column density ($N_\mathrm{H2O}\sim 3\times10^{20}\ \mathrm{cm}^{-2}$), and turbulent broadening ($v\sim 10$ km s$^{-1}$), but very small emitting area ($A\lesssim0.005$ AU$^2$). Similarity with previously observed water emission from V1331 Cyg (Doppmann et al. 2011) and SVS 13 (Carr et al. 2004) suggests that the presence of such a reservoir may be linked to evolutionary state, perhaps related to the presence of high accretion rates or winds. While the inner disk may harbor such a reservoir, simple Keplerian models do not match well with emitting line shapes, and alternative velocity fields must be considered. We also present a new idea, that the unusual emission could arise in a circumplanetary disk, embedded within the larger VV CrA A protoplanetary disk. Additional data are likely required to determine the true physical origin of this unusual spectral pattern.Comment: 32 pages, 17 figures, 5 appendix figures, 2 tables. Accepted for publication in Ap

Rabies Diagnosis for Developing Countries

A new diagnostic test for rabies in animals was evaluated in N'Djaména, capital of Chad. The test is based on a direct immuno-histochemical detection of rabies virus in brain tissue (dRIT) visible by normal light microscopy. Rabies detection by dRIT light microscopy is 10 times less expensive than fluorescence microscopy required for the current gold standard of rabies diagnosis. The test showed ideal results in fresh samples with 100% agreement with the gold standard and confirms the results of a first study in Tanzania. Thus, it has a significant potential for diagnosing rabies in low-income countries, and under field conditions where rabies diagnosis is unavailable for the moment. This new test opens up a great potential to train technical staff and to establish rabies diagnosis without delay in low-income countries with urban rabies

Volcanic ash layer depth: processes and mechanisms

The long duration of the 2010 Eyjafjallajökull eruption provided a unique opportunity to measure a widely dispersed volcanic ash cloud. Layers of volcanic ash were observed by the European Aerosol Research Lidar Network with a mean depth of 1.2 km and standard deviation of 0.9 km. In this paper we evaluate the ability of the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME) to simulate the observed ash layers and examine the processes controlling their depth. NAME simulates distal ash layer depths exceptionally well with a mean depth of 1.2 km and standard deviation of 0.7 km. The dominant process determining the depth of ash layers over Europe is the balance between the vertical wind shear (which acts to reduce the depth of the ash layers) and vertical turbulent mixing (which acts to deepen the layers). Interestingly, differential sedimentation of ash particles and the volcano vertical emission profile play relatively minor roles

Constraining remote oxidation capacity with ATom observations

The global oxidation capacity, defined as the tropospheric mean concentration of the hydroxyl radical (OH), controls the lifetime of reactive trace gases in the atmosphere such as methane and carbon monoxide (CO). Models tend to underestimate the methane lifetime and CO concentrations throughout the troposphere, which is consistent with excessive OH. Approximately half of the oxidation of methane and non-methane volatile organic compounds (VOCs) is thought to occur over the oceans where oxidant chemistry has received little validation due to a lack of observational constraints. We use observations from the first two deployments of the NASA ATom aircraft campaign during July-August 2016 and January-February 2017 to evaluate the oxidation capacity over the remote oceans and its representation by the GEOS-Chem chemical transport model. The model successfully simulates the magnitude and vertical profile of remote OH within the measurement uncertainties. Comparisons against the drivers of OH production (water vapor, ozone, and NOy concentrations, ozone photolysis frequencies) also show minimal bias, with the exception of wintertime NOy. The severe model overestimate of NOy during this period may indicate insufficient wet scavenging and/or missing loss on sea-salt aerosols. Large uncertainties in these processes require further study to improve simulated NOy partitioning and removal in the troposphere, but preliminary tests suggest that their overall impact could marginally reduce the model bias in tropospheric OH. During the ATom-1 deployment, OH reactivity (OHR) below 3 km is significantly enhanced, and this is not captured by the sum of its measured components (cOHRobs) or by the model (cOHRmod). This enhancement could suggest missing reactive VOCs but cannot be explained by a comprehensive simulation of both biotic and abiotic ocean sources of VOCs. Additional sources of VOC reactivity in this region are difficult to reconcile with the full suite of ATom measurement constraints. The model generally reproduces the magnitude and seasonality of cOHRobs but underestimates the contribution of oxygenated VOCs, mainly acetaldehyde, which is severely underestimated throughout the troposphere despite its calculated lifetime of less than a day. Missing model acetaldehyde in previous studies was attributed to measurement uncertainties that have been largely resolved. Observations of peroxyacetic acid (PAA) provide new support for remote levels of acetaldehyde. The underestimate in both model acetaldehyde and PAA is present throughout the year in both hemispheres and peaks during Northern Hemisphere summer. The addition of ocean sources of VOCs in the model increases cOHRmod by 3 % to 9 % and improves model-measurement agreement for acetaldehyde, particularly in winter, but cannot resolve the model summertime bias. Doing so would require 100 Tg yr-1 of a longlived unknown precursor throughout the year with significant additional emissions in the Northern Hemisphere summer. Improving the model bias for remote acetaldehyde and PAA is unlikely to fully resolve previously reported model global biases in OH and methane lifetime, suggesting that future work should examine the sources and sinks of OH over land
