Abstract
Introduction
There is paucity of data around the support that medical students have been provided with, need to be provided with, and would like to be provided with during the COVID-19 pandemic. This study sought to explore the effects of the COVID-19 pandemic on medical students and establish the support they require.

Methods
A prospective, observational, multicentre study was conducted in 2020. All medical students and interim foundation year 1 doctors were eligible to participate.

Results
Six hundred forty individuals participated from 32 medical schools. Participants reported a drop in their mood following the onset of the pandemic (p < 0.001). This drop in mood was evident in both May and August. Participants did have an improved mood in August compared to May (p < 0.001). There was a significant decrease in pandemic disease-anxiety (13.8/20 to 12.4/20, p < 0.001) and consequence-anxiety (6.3/10 to 6.0/10, p < 0.001) between May and August. Nineteen percent of participants (n = 111/596, 19%) had not received the support they needed from their university by August. The most common area of support that our participants needed and had not received from their medical schools by August was support with course material (n = 58/111, 52%). ‘Clinical knowledge’ was thought to have been affected by the greatest number of participants in both May and August.

Conclusion
Medical students’ mental well-being has been adversely affected during the COVID-19 pandemic. Our findings have actionable implications that can better protect medical students as they acclimatise to a working environment that has been radically changed by COVID-19.
“They Just Want Us to Exist as a Trash Can”: Parents of Children with Autism Spectrum Disorder and Their Perspectives to School-Based Bullying Victimization
Authors: Zhang Hui , Chen Chun 
Published: July 2021

AbstractLittle is known about parents’ perspectives on school-based bullying victimization of children with autism spectrum disorder (ASD) in China. This study began by interviewing 16 parents about their experiences with their children (7 to 15 years old) at school in China under the inclusive education policy. Most of the parents’ responses indicated the existence and the severity of school-based bullying victimization of their children with ASD. Our findings indicated that bullying victimization at school was a concern for children with ASD and their parents were frequently victimized. Parents reported that they dealt with bullying victims at school independently and tended to hold a pessimistic view about their bullying victimization. The study highlights the importance of incorporating parents’ voices in understanding bullying victimization of students with ASD and proposing potential implications in bullying prevention and advocacy with this group of students in mainstream schools in China.
On the dark side of open access and new expectations of scientific productivity in adult education research
Authors: Vetter Tim , Schemmann Michael 
Published: July 2021

AbstractThe aim of this paper is to explore international adult education research in the context of predatory publishing or predatory journals. The paper presents empirical characteristics of predatory journals, determines the quantitative occurrence of predatory journals in the field of adult education by means of a catalogue of criteria, takes a closer look at the authors of adult education contributions identified, and examines the content and quality of the contributions. The article deals with the phenomenon of predatory publishing, an unintended side effect of the Open Access movement, and thus operates in the context of Open Science.
Global searches of frozen orbits around an oblate Earth-like planet
Authors: Ma Yuechen , He Yanchao , Xu Ming , Zheng Yaru 
Published: July 2021

AbstractA frozen orbit is beneficial for observation owing to its stationary apsidal line. The traditional gravitational field model of frozen orbits only considers the main zonal harmonic terms J2 and limited high-order terms, which cannot meet the stringent demands of all missions. In this study, the gravitational field is expanded to J15 terms and the Hamiltonian canonical form described by the Delaunay variables is used. The zonal harmonic coefficients of the Earth are chosen as the sample. Short-periodic terms are eliminated based on the Hori–Lie transformation. An algorithm is developed to solve all equilibrium points of the Hamiltonian function. A stable frozen orbit with an argument of perigee that equals neither 90◦ nor 270◦ is first reported in this paper. The local stability and topology of the equilibrium points are obtained from their eigenvalues. The bifurcations of the equilibrium points are presented by drawing their global long-term evolution of frozen orbits and their orbital periods. The relationship between the terms of the gravitational field and number of frozen points is addressed to explain why only limited frozen orbits are found in the low-order term case. The analytical results can be applied to other Earth-like planets and asteroids.
Semiarid bunchgrasses accumulate molybdenum on alkaline copper mine tailings: assessing phytostabilization in the greenhouse

Published: July 2021

AbstractPhytostabilization is the use of plants and soil amendments to physically stabilize and remediate contaminated mine wastes and to control wind and water erosion in semiarid environments. The aim of this study was to evaluate two native bunchgrass species’ (Pseudoroegneria spicata and Festuca campestris) biomass accumulation and metals uptake response to locally available soil amendments (compost, wood ash and wood chips) to determine their suitability for phytostabilization at an alkaline copper mine tailings site in British Columbia, Canada. In the greenhouse, bunchgrasses important as forage for livestock and wildlife were grown in tailings with various ash–compost–wood chip combinations and evaluated using a randomized complete block design with 13 treatments and 10 replicates. Plants were harvested after 90 d, and tissues were analyzed for root and shoot biomass. Tissue samples (n = 3) from three treatment subsets (ash, compost, blend) were selected for elemental analysis. Biomass increased with increasing compost applications, and the response was greatest for P. spicata. Shoot molybdenum exceeded the maximum tolerable level for cattle and was significantly higher when grasses were grown on the ash treatment (183–202 mg kg−1) compared to the others (19.7–58.3 mg kg−1). Translocation and root bioconcentration factors were highest on the ash treatment (2.53–12.5 and 1.75–7.96, respectively) compared to the other treatments (0.41–3.43 and 1.47–4.79, respectively) and indicate that both species are ‘accumulators.’ The findings suggest that these bunchgrasses were not ideal candidates for phytostabilization due to high shoot tissue molybdenum accumulation, but provide important considerations for mine restoration in semiarid grassland systems.
ArcGIS Urban: an application for plan assessment
Authors: Soward Ellen , Li Jianling 
Published: July 2021

AbstractMost cities in the United States rely on zoning to address important planning-related issues within their jurisdictions. Planners often use GIS tools to analyze these issues in a spatial context. ESRI’s ArcGIS Urban software seeks to provide the planning profession with a GIS-based solution for various challenges, including zoning’s impacts on the built environment and housing capacity.This research explores the use of ArcGIS Urban for assessing the existing zoning and comprehensive plans in meeting the projected residential growth in the near future using the City of Arlington, Texas as a case study. The exploration provides examples and lessons for how ArcGIS Urban might be used by planners to accomplish their tasks and highlights the capabilities and limitations of ArcGIS Urban in its current stand. The paper is concluded with some suggestions for future studies.
The Un-meeting approach to stimulate collaborative adult learning: an application for clinical research professionals

Published: July 2021

AbstractWe used a Zoom Un-meeting as an educational approach to provide experienced clinical research professional (CRP) adult learners a collaborative learning space to learn more about current issues for academic medical center (AMC) clinical research workforce development and collaborate on solution finding. CRPs operationalize the conduct of clinical trials and represent a significant brain trust for the Clinical and Translational Science (CTSA) consortium hubs with their vast knowledge base, extensive experience, understanding of relevant institutional policy, organizational culture, and clinical research operations. Un-meetings are an intentionally organized and coordinated group activity that encourages participants to focus on a topic and incorporate an open flow of ideas through brainstorming and an open discussion format, setting the stage for future collaborative action. We divided topics into a series of six consecutive monthly Un-meeting Zoom workshops. Ultimately, one resulting output from the meeting was the Center for Leading Innovation and Collaborations (CLIC) synergy paper award to support continued collaborative work. Currently, work teams have emerged to analyze qualitative data from brainstorming and breakout session recordings and to identify small-group activities. We describe this adult learning tool as valuable for exploring issues of AMC CRP professional development. This approach encouraged creative/critical thinking and opportunities for leadership, team science, and problem-solving among participants.

AbstractObjective:Our objective was to compare care-seeking patterns in Mosul, Iraq, in 2018, 1 y after Islamic State of Iraq and Syria (ISIS) control, with findings from neighborhoods that had been sampled in 2017Methods:For this multi-stage randomized cluster household survey, we created one cluster in each of 20 neighborhoods randomly selected from the 40 neighborhoods in the 2016/17 survey; 12 in east Mosul, 8 in west Mosul. In each, 30 households were interviewed beginning at a randomly selected start house. Questions were derived from the 2016/2017 post-ISIS survey.Results:We interviewed the head of household or senior female in 600 households containing 3375 persons. One year after ISIS, some household demographic shifts had occurred. Diarrhea in children during the past 2 wk decreased from 50.1% to 7.5% (P < 0.001); however, cough/difficulty breathing increased from 15.5% to 33.6% (P < 0.01). Among adults, care-seeking for noncommunicable diseases increased from 22.3% to 43.5% (P < 0.001). Emotional and psychological complaints common in the previous survey were now nearly absent. Pregnancy complications diminished from 65.2% to 15.4% (P < 0.001).Conclusions:Communicable diseases predominated among children and noncommunicable diseases among adults. Access to health care substantially improved, although barriers remained. Satisfaction with services was mixed, with dissatisfaction expressed about testing, medicine access, and costs, but the work of health providers was rated highly.

Authors: Durgut Utku , Yildiz Tulin 
Published: July 2021

AbstractObjective:This study aimed to carry out the validity and reliability study for the adaptation of the Competencies for Disaster Nursing Management Questionnaire (CDNMQ), which was developed by Al Thobaity and others in 2016, (https://pubmed.ncbi.nlm.nih.gov/26778698/) to Turkish, and to be able to use in the nursing literature.Method:This study was conducted in a methodological approach. The scale used in this study was a 10-point Likert scale with 43 items and 3 subfactors. The questionnaire was applied to 450 nurses. The validity and reliability of the scale were evaluated using the exploratory and confirmatory factor analysis. The content validity index was measured within the scope of the internal consistency measurements, and the Pearson’s product-moment correlation coefficient was examined for the test-retest.Results:The content validity index score was found to be 0.98. As a result of the confirmatory factor analysis of the CDNMQ, it was found that the 3-factor structure of the scale was valid and the goodness of fit tests was appropriate.Conclusion:The findings have shown that the CDNMQ study is similar to the original scale and an adequate measurement tool in determining competencies in disaster nursing management.
Risk of methicillin-resistantStaphylococcus aureus(MRSA) and vancomycin-resistantEnterococcus(VRE) acquisition during ambulance transport: A retrospective propensity-score–matched cohort analysis
Authors: Schaps Diego , Godfrey Andrew W. , Anderson Deverick J. 
Published: July 2021

AbstractObjective:To estimate the relative risk (RR) of developing methicillin-resistantStaphylococcus aureus(MRSA) or vancomycin-resistantEnterococcus(VRE) colonization or infection within 30 days of ambulance transport.Methods:We performed a retrospective cohort study of patients with a principal diagnosis of chest pain presenting to our emergency department (ED) over a 4-year period. Patients were included if they presented from and were discharged to nonhealthcare locations without being admitted. Encounters were stratified by arrival mechanism: ambulance versus private vehicle. We performed propensity score matching and multivariable logistic regression to estimate the RR for the primary outcome.Results:In total, 321,229 patients had ED encounters during the study period. After applying inclusion criteria and propensity score matching, there were 11,324 patients: 3,903 in the ambulance group and 7,421 in the unexposed group. Among them, 12 patients (0.11%) had the outcome of interest, including 9 (0.08%) with MRSA and 3 (0.03%) with VRE. The 30-day prevalence of MRSA or VRE was larger in the ambulance group than in the unexposed group: 8 (0.20%) and 4 (0.05%), respectively (P= .02). Patients who presented to the ED via ambulance were almost 4 times more likely to have MRSA or VRE within 30 days of their encounter (RR, 3.72; 95% CI, 1.09–12.71;P= .04).Conclusions:Our cohort study is the first to demonstrate an association between ambulance exposure and pathogen incidence, representing the first step in evaluating medical-transport–associated infection burden to eventually develop interventions to address it.

Published: July 2021

AbstractObjective:The coronavirus disease 2019 (COVID-19) vaccine may hold the key to ending the pandemic, but vaccine hesitancy is hindering the vaccination of healthcare personnel (HCP). We examined their perceptions of the COVID-19 vaccine and implemented an intervention to increase vaccination uptake.Design:Before-and-after trial.Participants and setting:Healthcare personnel at a 790-bed tertiary-care center in Tokyo, Japan.Interventions:A prevaccination questionnaire was administered to HCP to examine their perceptions of the COVID-19 vaccine. A multifaceted intervention was then implemented involving (1) distribution of informational leaflets to all HCP, (2) hospital-wide announcements encouraging vaccination, (3) a mandatory lecture, (4) an educational session about the vaccine for pregnant or breastfeeding HCP, and (5) allergy testing for HCP at risk of allergic reactions to the vaccine. A postvaccination survey was also performed.Results:Of 1,575 HCP eligible for enrollment, 1,224 (77.7%) responded to the questionnaire, 533 (43.5%) expressed willingness to be vaccinated, 593 (48.4%) were uncertain, and 98 (8.0%) expressed unwillingness to be vaccinated. The latter 2 groups were concerned about the vaccine’s safety rather than its efficacy. After the intervention, the overall vaccination rate reached 89.7% (1,413 of 1,575), and 88.9% (614 of 691) of the prevaccination survey respondents answered “unwilling” to or “unsure” about eventually receiving a vaccination. In the postvaccination questionnaire, factors contributing to increased COVID-19 vaccination included information and endorsement of vaccination at the medical center (274 of 1,037, 26.4%).Conclusions:This multifaceted intervention increased COVID-19 vaccinations among HCP at a Japanese hospital. Frequent support and provision of information were crucial for increasing the vaccination rate and may be applicable to the general population as well.
“Is This Not Just Nationalism?” Disentangling the Threads of Folk Costumes in the History of Central and Eastern Europe
Authors: Geering Corinne 
Published: July 2021

AbstractThis article critically examines the prevalent nationalist interpretation of historical images featuring textiles from rural regions. In an effort to disentangle the threads of folk costumes, it proposes a conscious unlearning of the way we read images of rural material culture from the late 19th century. This period has entered historiography as a period of intensifying national movements and political use of rural culture, in particular in Central and Eastern Europe. So-called folk costumes have been viewed as a symbolic representation of the nation, whereas their broader social and economic role in the history of industrial society has been overshadowed. By bringing together the production, collection, and exhibition of rural material culture, this article reveals processes in industrial society that shaped the modern history of folk costumes. It draws on late-19th-century source material stemming from a network centered in Prague that promoted textiles from rural Bohemia, Moravia, Hungary, and Galicia as ethno-commodities. Textiles were integrated into women’s industrial education and presented at events promoting national economy and the latest technological innovations. Thus, this article contributes to nationalism studies by discussing capitalism and industrialism and seeks to further scrutinize the history of nationalism in Central and Eastern Europe.
BOMB-PRODUCED RADIOCARBON ACROSS THE SOUTH PACIFIC GYRE—A NEW RECORD FROM AMERICAN SAMOA WITH UTILITY FOR FISHERIES SCIENCE
Authors: Andrews Allen H , Prouty Nancy G , Cheriton Olivia M 
Published: July 2021

ABSTRACTCoral skeletal structures can provide a robust record of nuclear bomb produced 14C with valuable insight into air-sea exchange processes and water movement with applications to fisheries science. To expand these records in the South Pacific, a coral core from Tutuila Island, American Samoa was dated with density band counting covering a 59-yr period (1953–2012). Seasonal signals in elemental ratios (Sr/Ca and Ba/Ca) and stable carbon (δ13C) values across the coral core corroborated the well-defined annual band structure and highlighted an ocean climate shift from the 1997–1998 El Niño. The American Samoa coral 14C measurements were consistent with other regional records but included some notable differences across the South Pacific Gyre (SPG) at Fiji, Rarotonga, and Easter Island that can be attributed to decadal ocean climate cycles, surface residence times and proximity to the South Equatorial Current. An analysis of the post-peak 14C decline associated with each coral record indicated 14C levels are beginning to merge for the SPG. This observation, coupled with otolith measurements from American Samoa, reinforces the perspective that bomb 14C dating can be performed on fishes and other marine organisms of the region using the post-peak 14C decline to properly inform fisheries management in the South Pacific.

AbstractLet
$f(x)\in \mathbb {Z}[x]$
be a nonconstant polynomial. Let
$n\ge 1, k\ge 2$
and c be integers. An integer a is called an f-exunit in the ring
$\mathbb {Z}_n$
of residue classes modulo n if
$\gcd (f(a),n)=1$
. We use the principle of cross-classification to derive an explicit formula for the number
${\mathcal N}_{k,f,c}(n)$
of solutions
$(x_1,\ldots ,x_k)$
of the congruence
$x_1+\cdots +x_k\equiv c\pmod n$
with all
$x_i$
being f-exunits in the ring
$\mathbb {Z}_n$
. This extends a recent result of Anand et al. [‘On a question of f-exunits in
$\mathbb {Z}/{n\mathbb {Z}}$
’, Arch. Math. (Basel)116 (2021), 403–409]. We derive a more explicit formula for
${\mathcal N}_{k,f,c}(n)$
when
$f(x)$
is linear or quadratic.

AbstractThe association between the intake of non-alcoholic beverages and CVD in Asians is uncertain. The intake of non-alcoholic beverages was estimated in 77 407 participants of the Japan Public Health Centre-based cohort study aged 45–74 years. The Cox regression calculated the hazard ratios (HR) and 95 % CI for incident CVD according to sex-specific quintiles of intake of non-alcoholic beverages. A total of 4578 incident CVD (3751 strokes and 827 CHD) were diagnosed during a 13·6-year median follow-up. The risks of stroke and total CVD were lower for the highest v. lowest intake quintiles of non-alcoholic beverages in men and women: the multivariable HRs (95 % CIs) were 0·82 (0·71, 0·93, Ptrend = 0·005) and 0·86 (0·76, 0·97, Ptrend = 0·02), respectively, in men and were 0·73 (0·63, 0·86, Ptrend = 0·003) and 0·75 (0·65, 0·87, Ptrend = 0·005), respectively, in women. The reduced risk was evident for both ischaemic and haemorrhagic strokes and was mainly attributable to green tea consumption. The intake of non-alcoholic beverages from coffee and other beverages was not associated with the risk of CVD in both men and women. Also, there was no association between the intake of non-alcoholic beverages and the risk of CHD in either sex. In conclusion, the risks of stroke and total CVD were lower with a higher intake of non-alcoholic beverages in Japanese men and women.
