Educators’ experiences and strategies for responding to ecological distress
Authors: Verlie Blanche , Clark Emily , Jarrett Tamara , Supriyono Emma 
Published: December 2020

AbstractResearch is increasingly identifying the issues of ecological distress, eco-anxiety and climate grief. These painful experiences arise from heightened ecological knowledge and concern, which are commonly considered to be de facto aims of environmental education. Yet little research investigates the issues of climate change anxiety in educational spaces, nor how educators seek to respond to or prevent such emotional experiences. This study surveyed environmental educators in eastern Australia about their experiences and strategies for responding to their learners’ ecological distress. Educators reported that their students commonly experienced feeling overwhelmed, hopeless, anxious, angry, sad and frustrated when engaging with ecological crises. Educators’ strategies for responding to their learners’ needs included encouraging students to engage with their emotions, validating those emotions, supporting students to navigate and respond to those emotions and empowering them to take climate action. Educators felt that supporting their students to face and respond to ecological crises was an extremely challenging task, one which was hindered by time limitations, their own emotional distress, professional expectations, society-wide climate denial and a lack of guidance on what works.
THE IMPACTS OF INDIVIDUAL INFORMATION ON LOSS RESERVING
Authors: Wang Zhigao , Wu Xianyi , Qiu Chunjuan 
Published: December 2020

AbstractThe projection of outstanding liabilities caused by incurred losses or claims has played a fundamental role in general insurance operations. Loss reserving methods based on individual losses generally perform better than those based on aggregate losses. This study uses a parametric individual information model taking not only individual losses but also individual information such as age, gender, and so on from policies themselves into account. Based on this model, this study proposes a computation procedure for the projection of the outstanding liabilities, discusses the estimation and statistical properties of the unknown parameters, and explores the asymptotic behaviors of the resulting loss reserving as the portfolio size approaching infinity. Most importantly, this study demonstrates the benefits of individual information on loss reserving. Remarkably, the accuracy gained from individual information is much greater than that from considering individual losses. Therefore, it is highly recommended to use individual information in loss reserving in general insurance.

Abstract
CTSI Career Development Award (KL2) programs provide junior faculty with protected time and multidisciplinary, mentored research training in clinical and translational science research. The KL2 Visiting Scholars Program was developed to promote collaborative cross-CTSA training, leverage academic strengths at host CTSAs, and support the career development of participating scholars through experiential training and the development of new partnerships. This manuscript provides a detailed programmatic description and reports outcomes from post-visit and outcomes surveys. Since 2016, 12 scholars have completed the program, with 6 scheduled to complete it in 2021. Post-visit surveys (n = 12) indicate all scholars reported the program valuable to career development, 11 reported benefit for research development, and 11 expansion of collaborative networks. Outcomes surveys (n = 11) revealed subsequent scholar interaction with host institution faculty for 10 scholars, 2 collaborative grant submissions (1 funded), 2 planned grant submissions, 1 published collaborative manuscript, and 3 planned manuscript/abstract submissions. The Visiting Scholars Program is a cost- and time-efficient program that leverages the academic strengths of CTSAs. The program enhanced KL2 scholar training by expanding their professional portfolio, promoting research development, and expanding collaborative networks. Resources to support the program are shared in this report to expedite the development of similar programs at regional and national levels.

Abstract
A late Pleistocene glaciolacustrine record was studied at Fagnano Lake (54°35´S, 67°20´W), central Isla Grande de Tierra del Fuego, southernmost South America. Two profiles from the Río Valdéz outcrop were collected for isotopic, geochemical, sedimentological, and geophysical analyses. The sedimentological characteristics, such as rhythmites, presence of dropstones, absence of fossil record, and scarce presence of organic matter, suggest deposition in an ice-contact lake, possibly dammed by the Fagnano paleoglacier. Organic matter of C3 plant origin suggests certain cold and wet conditions. A chronology of the late Pleistocene outcrop was obtained from five 14C ages resulting in an age-depth model. The time span covered 49.01 cal ka BP to 32.14 cal ka BP. Based on the thickness of the deposit and the calculated average sedimentation rate, the glacial environment could have been present in the study area prior to the last glacial maximum, in agreement with the Inútil-San Sebastián paleoglacier. Both glaciers flowed from the same mountain ice sheet in the Darwin Cordillera, which makes it possible to infer a different behavior of this ice cap from those of the Patagonian Andes, perhaps forced by different atmospheric dynamics and proximity to the wet and cold subantarctic air masses.

be the set of vertices and by drawing an edge between distinct elements

$x,y\in G^{\scriptsize\#}$
if and only if the subgroup

$\langle x,y\rangle $
is cyclic. Recall that a Z-group is a group where every Sylow subgroup is cyclic. In this short note, we investigate

Published: December 2020

AbstractObjectiveTo evaluate voice intensity as the primary outcome measurement when treating unilateral vocal fold paralysis patients.MethodsThis prospective observational study comprised 34 newly diagnosed unilateral vocal fold paralysis patients undergoing surgical interventions: injection laryngoplasty or medialisation thyroplasty. Voice assessments, including maximum vocal intensity and other acoustic parameters, were performed at baseline and at one and three months post-intervention. Maximum vocal intensity was also repeated within two weeks before any surgical interventions were performed. The results were compared between different time points and between the two intervention groups.ResultsMaximum vocal intensity showed high internal consistency. Statistically significant improvements were seen in maximum vocal intensity, Voice Handicap Index-10 and other acoustic analyses at one and three months post-intervention. A significant moderate negative correlation was demonstrated between maximum vocal intensity and Voice Handicap Index-10, shimmer and jitter. There were no significant differences in voice outcomes between injection laryngoplasty and medialisation thyroplasty patients at any time point.ConclusionMaximum vocal intensity can be applied as a treatment outcome measure in unilateral vocal fold paralysis patients; it can demonstrate the effectiveness of treatment and moderately correlates with self-reported outcome measures.
Resilience in a changing world: Indigenous sharing networks in the Republic of Sakha (Yakutia)
Authors: Solovyeva Vera , Kuklina Vera 
Published: December 2020

AbstractGlobal change poses challenges for remote Arctic Russian indigenous communities in the Republic of Sakha. On the basis of interviews from the village of Khara Tumul (Oymyakonskiy ulus) and city of Yakutsk, we illustrate the manners in which sharing networks may be used to enhance resilience in remote conditions as these communities confront climate change, industrial development and limited support from authorities. We identified the main carriers (givers and recipients), location, relationships and mediators, objects, and social and cultural meanings of sharing practices both in daily life and in the case of extreme events. The circulation of goods, money, information and people between cities and remote communities ultimately combines traditional values and modern technologies.
Where’s the body? Reconsidering the concept of pedagogical content knowledge through research in music education with Dutch specialist preschool music teachers
Authors: Bremmer Melissa 
Published: December 2020

AbstractThis article reports an investigation into the pedagogical content knowledge (PCK) of Dutch specialist preschool music teachers with regard to teaching and learning rhythm skills from an embodied cognition perspective. An embodied cognition perspective stresses the intimate relationship between body, mind and environment. Through stimulated recall interviews, video analysis tasks, notebooks and semi-structured interviews, the PCK of six music teachers was explored. Regarding the content, a new form of bodily based PCK was found in the data: instructional gestures, representational gestures and guiding gestures that facilitate the learning of rhythm skills of preschoolers. Regarding its nature, this study demonstrated that the music teacher’s PCK presents itself as a multimodal form of knowing, distributed over language, sound, gestures, body positioning and physical actions. This study raises the question whether the body is marginalised in current conceptualisations of PCK.
Expanding Higher Education: China's Precarious Balance
Authors: Postiglione Gerard A. 
Published: December 2020

AbstractChina implemented an unprecedented expansion of higher education along with excellence initiatives that propelled more universities into the global rankings. Yet, the international influence of the higher education system pales in comparison to its economy. This paper argues that governance reforms in higher education only partially address the increasingly complex social and geopolitical realities. With more institutional and professional autonomy, universities and the academic research enterprise would be better placed and more inclined to find innovative solutions to urgent problems of domestic and global sustainability.

Published: December 2020

AbstractObjectives:To assess the overall burden and outcomes of acute respiratory infections in paediatric inpatients with congenital heart disease (CHD).Methods:This is a retrospective cross-sectional study of non-neonates <1 year with CHD in the Kid’s Inpatient Database from 2012. We compared demographics, clinical characteristics, cost, length of stay, and mortality rate for those with and without respiratory infections. We also compared those with respiratory infections who had critical CHD versus non-critical CHD. Multi-variable regression analyses were done to look for associations between respiratory infections and mortality, length of stay, and cost.Results:Of the 28,696 infants with CHD in our sample, 26% had respiratory infections. Respiratory infection-associated hospitalisations accounted for $440 million in costs (32%) for all CHD patients. After adjusting for confounders including severity, mortality was higher for those with respiratory infections (OR 1.5, p = 0.003), estimated mean length of stay was longer (14.7 versus 12.2 days, p < 0.001), and estimated mean costs were higher ($53,760 versus $46,526, p < 0.001). Compared to infants with respiratory infections and non-critical CHD, infants with respiratory infections and critical CHD had higher mortality (4.5 versus 2.3%, p < 0.001), longer mean length of stay (20.1 versus 15.5 days, p < 0.001), and higher mean costs ($94,284 versus $52,585, p < 0.001).Conclusion:Acute respiratory infections are a significant burden on infant inpatients with CHD and are associated with higher mortality, costs, and longer length of stay; particularly in those with critical CHD. Future interventions should focus on reducing the burden of respiratory infections in this population.

AbstractBackground:Understanding the impact of the COVID-19 pandemic on paediatric non-COVID-19-related care, as well as patient and caregiver concerns and stressors, is critical for informing healthcare delivery. It was hypothesised that high care disruptions and psychological stress would be observed among paediatric and adult CHD patients in the early phase of the pandemic.Methods:A cross-sectional, international, electronic survey study was completed. Eligible participants included parents of children with acquired or CHD, adults with CHD, or caregivers of adults with CHD.Results:A total of 1220 participants from 25 countries completed the survey from 16 April to 4 May, 2020. Cardiac care disruption was significant with 38% reporting delays in pre-pandemic scheduled cardiac surgeries and 46% experiencing postponed cardiac clinic visits. The majority of respondents (75%) endorsed moderate to high concern about the patient with heart disease becoming ill from COVID-19. Worry about returning for in-person care was significantly greater than worry of harm to patient due to postponed care. Clinically significant psychological stress was high across the sample including children (50%), adults with CHD (42%), and caregivers (42%).Conclusions:The early phase of the COVID-19 pandemic contributed to considerable disruptions in cardiac care for patients with paediatric and adult CHD. COVID-19-related fears are notable with potential to impact willingness to return to in-person care. Psychological stress is also very high necessitating intervention. Further study of the impact of delays in care on clinical outcomes is warranted.

AbstractObjective:To use Internet search data to compare duration of compliance for various diets.Design:Using a passive surveillance digital epidemiological approach, we estimated the average duration of diet compliance by examining monthly Internet searches for recipes related to popular diets. We fit a mathematical model to these data to estimate the time spent on a diet by new January dieters (NJD) and to estimate the percentage of dieters dropping out during the American winter holiday season between Thanksgiving and the end of December.Setting:Internet searches in the USA for recipes related to popular diets over a 15-year period from 2004 to 2019.Participants:Individuals in the USA performing Internet searches for recipes related to popular diets.Results:All diets exhibited significant seasonality in recipe-related Internet searches, with sharp spikes every January followed by a decline in the number of searches and a further decline in the winter holiday season. The Paleo diet had the longest average compliance times among NJD (5.32 ± 0.68 weeks) and the lowest dropout during the winter holiday season (only 14 ± 3 % dropping out in December). The South Beach diet had the shortest compliance time among NJD (3.12 ± 0.64 weeks) and the highest dropout during the holiday season (33 ± 7 % dropping out in December).Conclusions:The current study is the first of its kind to use passive surveillance data to compare the duration of adherence with different diets and underscores the potential usefulness of digital epidemiological approaches to understanding health behaviours.
Assessing sugar-sweetened beverage intakes, added sugar intakes and BMI before and after the implementation of a sugar-sweetened beverage tax in South Africa

Published: December 2020

AbstractObjective:To provide insight into the context and public health implications of the South African sugar-sweetened beverage (SSB) tax (Health Promotion Levy; HPL) by describing SSB and added sugar intakes, as well as BMI, 1 year prior to, at the time of and 1 year after implementation of the HPL.Design:Longitudinal dietary intake was assessed using a quantitative food frequency questionnaire (QFFQ) and BMI was measured via anthropometry.Setting:Soweto, Johannesburg, South Africa.Participants:Adolescents, young adults and middle-aged adults (n 617).Results:At baseline, median SSB intakes were 36 ml/d, 214 ml/d and 750 ml/d for those in low, medium and high consumption tertiles, respectively. SSB intake decreased by two times/week in medium consumers and seven times/week in high consumers between baseline and 12 months, equivalent to 107 ml/d and 536 ml/d reductions, respectively. These reduced levels were maintained in the following year (i.e. to 24 months). There was an overall decrease in the amount of energy consumed as added sugar in the low (−48 kJ/d), medium (−153 kJ/d) and high (−106 kJ/d) SSB consumption groups between baseline and 24 months; however, the percentage of total energy consumed as added sugar remained relatively consistent (between 10 and 11 %). There were small overall increases in BMI across low (0·6 kg/m2), medium (0·9 kg/m2) and high (1·0 kg/m2) SSB tertiles between baseline and 24 months.Conclusions:These findings suggest reductions in SSB and added sugar consumption contemporaneous to the introduction of the HPL – particularly for those with higher baseline intakes.

AbstractBackground:The present study reports myeloablative total body irradiation (TBI) on an isocentrically mounted linac by laying the patient on the floor and management of abutting radiation fields and partial shielding of lungs. Dosimetrical efficacy of this novel technique was evaluated.Materials and methods:In this retrospective study, dosimetrical parameters from TBI plans on whole-body CT scans of 46 patients were analysed. The prescribed dose to TBI was 12 Gy in six fractions delivered over a period of 3 days for myeloablative conditioning. TrueBeam STx platform Linac (Varian Medical Systems Inc., Palo Alto, CA, USA) was used to deliver opposing fields. Radiation fields were abutted to form a single large field using an arithmetic formula at source-to-skin-distance of 210 cm.Results:Discrepancies in dose calculated by treatment planning system were within 1·6% accuracy, and dose profile at the junction of abutting radiation fields was reproduced within 3·0% accuracy. The real treatment time for each patient was ~30 minutes/fraction. Monitor unit was weighted for multiple sub-fields to achieve dose homogeneity within 5·0% throughout the whole body, and the mean dose to lung was ≤10 Gy.Conclusion:Our abutting radiation field technique for myeloablative TBI is feasible in any existing linac bunker. ‘Island-blocking’ is feasible in this technique using multi-leaf collimator. This technique is cost-effective as it does not require any costly equipment than the readily available equipment in any radiotherapy facility. In general, TBI requires laborious planning procedures and spacious linac bunkers; this novel technique has the potential to change previously held notions.

AbstractThe manipulation of articulated objects is of primary importance in Robotics and can be considered as one of the most complex manipulation tasks. Traditionally, this problem has been tackled by developing ad hoc approaches, which lack flexibility and portability. In this paper, we present a framework based on answer set programming (ASP) for the automated manipulation of articulated objects in a robot control architecture. In particular, ASP is employed for representing the configuration of the articulated object for checking the consistency of such representation in the knowledge base and for generating the sequence of manipulation actions. The framework is exemplified and validated on the Baxter dual-arm manipulator in the first, simple scenario. Then, we extend such scenario to improve the overall setup accuracy and to introduce a few constraints in robot actions execution to enforce their feasibility. The extended scenario entails a high number of possible actions that can be fruitfully combined together. Therefore, we exploit macro actions from automated planning in order to provide more effective plans. We validate the overall framework in the extended scenario, thereby confirming the applicability of ASP also in more realistic Robotics settings and showing the usefulness of macro actions for the robot-based manipulation of articulated objects.
