Experimenter as automaton; experimenter as human: exploring the position of the researcher in scientific research
Authors: Field Sarahanne M. , Derksen Maarten 
Published: November 2020

AbstractThe crisis of confidence in the social sciences has many corollaries which impact our research practices. One of these is a push towards maximal and mechanical objectivity in quantitative research. This stance is reinforced by major journals and academic institutions that subtly yet certainly link objectivity with integrity and rigor. The converse implication of this may be an association between subjectivity and low quality. Subjectivity is one of qualitative methodology’s best assets, however. In qualitative methodology, that subjectivity is often given voice through reflexivity. It is used to better understand our own role within the research process, and is a means through which the researcher may oversee how they influence their research. Given that the actions of researchers have led to the poor reproducibility characterising the crisis of confidence, it is worthwhile to consider whether reflexivity can help improve the validity of research findings in quantitative psychology. In this report, we describe a combination approach of research: the data of a series of interviews helps us elucidate the link between reflexive practice and quality of research, through the eyes of practicing academics. Through our exploration of the position of the researcher in their research, we shed light on how the reflections of the researcher can impact the quality of their research findings, in the context of the current crisis of confidence. The validity of these findings is tempered, however, by limitations to the sample, and we advise caution on the part of our audience in their reading of our conclusions.

Published: November 2020

BACKGROUND:
Public health measures were instituted to reduce COVID-19 spread. A decrease in total emergency department volume followed, but the impact on injury is unknown. With lockdown and social distancing potentially increasing domicile discord, we hypothesized that intentional injury increased during COVID-19, driven primarily by an increase in penetrating trauma.

STUDY DESIGN:
A retrospective review of acute adult patient care in an urban Level I trauma center assessed injury patterns. Presenting patient characteristics and diagnoses from 6 weeks pre to 10 weeks post statewide stay-at-home orders (March 16, 2020) were compared, as well as with 2015-2019. Subsets were defined by intentionality (intentional vs nonintentional) and mechanism of injury (blunt vs penetrating). Fisher exact and Wilcoxon tests were used to compare proportions and means.

RESULTS:
There were 357 trauma patients that presented pre stay-at-home order and 480 that presented post stay-at-home order. Pre and post groups demonstrated differences in sex (35.6% vs 27.9% female; p = 0.02), age (47.4 ± 22.1 years vs 42 ± 20.3 years; p = 0.009), and race (1.4% vs 2.3% Asian; 63.3% vs 68.3% Black; 30.5% vs 22.3% White; and 4.8% vs 7.1% other; p = 0.03). Post stay-at-home order mechanism of injury revealed more intentional injury (p = 0.0008). Decreases in nonintentional trauma after adoption of social isolation paralleled declines in daily emergency department visits. Compared with earlier years, 2020 demonstrated a significantly greater proportion of intentional violent injury during the peripandemic months, especially from firearms.

CONCLUSIONS:
Unprecedented social isolation policies to address COVID-19 were associated with increased intentional injury, especially gun violence. Meanwhile, emergency department and nonintentional trauma visits decreased. Pandemic-related public health measures should embrace intentional injury prevention and management strategies.
Obesity population at risk of COVID-19 complications
Authors: Cuschieri Sarah , Grech Stephan 
Published: November 2020

Abstract

Introduction
Global public health is challenged by two concurrent epidemics; COVID-19 and obesity. Considering the global prevalence of obesity, exploring relationships with COVID-19 are of clinical importance. The aim was to provide a comprehensive summary and recommendations on this relationship between COVID-19 and obesity.

Method
A literature search was performed to prepare a narrative review of COVID-19 and obesity.

Results
An obesity state promotes chronic inflammation, vitamin D deficiency, hinders immunity and causes mechanical lung compression. These increase susceptibilities to COVID-19 infection, complications including the requirement of invasive ventilation. Existing co-morbidities enhances these complications. Preventive measures of social distancing and self-isolation may increase stigmatisation and psychological deterrents. Hence, special recommendations targeting this vulnerable population are required.

Conclusion
The obese population is a COVID-19 vulnerable group, requiring special attention during this pandemic to avoid complications and healthcare systems burden. Lacking COVID-19 vaccination, regular physical activity and a healthy diet are recommended with attention to mental health. A prolonged quarantine duration and administration of prophylactic vitamin D may be considered.
Retrospection, fairness, and economic shocks: how do voters judge policy responses to natural disasters?
Authors: Bechtel Michael M. , Mannino Massimo 
Published: November 2020

AbstractWhich factors explain voters’ evaluations of policy responses to economic shocks? We explore this question in the context of mass preferences over the distribution of disaster relief and evaluate three fairness-based explanations related to affectedness, need, and political ties. We analyze experimental data from an original survey conducted among American citizens and find that affectedness and need are key drivers of voters’ preferred disaster responses. We then compare these patterns with observed disaster relief distributions (1993–2008). The results suggest that observed relief allocations largely mirror the structure of voter preferences with respect to affectedness and need, but not to political ties. These findings have implications for an ongoing debate over the electoral effects of natural disasters, voters’ retrospective evaluations of incumbent performance, and the extent to which divide-the-dollar politics decisions align with mass preferences.
Deprivation or discrimination? Comparing two explanations for the reverse income–obesity gradient in the US and South Korea
Authors: Han SeungYong , Hruschka Daniel 
Published: November 2020

AbstractIn high-income countries, poverty is often associated with higher average body mass index (BMI). To account for this reverse gradient, deprivation theories posit that declining economic resources make it more difficult to maintain a healthy weight. By contrast, discrimination theories argue that anti-fat discrimination in hiring and marriage sorts heavier individuals into lower-income households. This study assesses competing predictions of these theories by examining how household income in representative samples from South Korea (2007–2014, N=20,823) and the US (1999–2014, N=6395) is related to BMI in two key contrasting groups: (1) currently-married and (2) never-married individuals. As expected by anti-fat discrimination in marriage, the reverse gradient is observed among currently-married women but not among never-married women in both countries. Also consistent with past studies no evidence was found for a reverse gradient among men. These findings are consistent with anti-fat discrimination in marriage as a key cause of the reverse gradient and raise serious challenges to deprivation accounts as well as explanations based on anti-fat discrimination in labour markets.

Published: November 2020

AbstractThe experiment described in this research communication aimed to compare the immunological traits of Simmental (sire) × Holstein (dam) crossbred cows with the two parental breeds in the peripartum and early lactation period and to estimate the effects of heterosis for these traits. Flow cytometric evaluation of leukocyte subpopulations was assessed in 16 Crossbred (CR), 8 Holstein (HO) and 8 Simmental (SI) cows. Estimated average values of innate and adaptive immune cells showed statistically significant differences between the crossbred cows and parental breeds. Interestingly, the most relevant differences between the three groups related to adaptive immune cells. In particular, the CR cows showed a lower percentage of CD3+ T lymphocytes compared with the SI group (P < 0.0001) and the highest proportions of CD21+ B lymphocytes among the three groups (P < 0.0001). Furthermore, we found the highest positive value of heterosis for the CD21+ B lymphocytes (7.0) and the lowest negative value for CD3+ T lymphocytes (−4.8) in F1 derived population. It seems reasonable to believe that these differences could affect immune function of crossbred cows.

Published: November 2020

SUMMARYA versatile architecture is presented to implement autonomous vehicles. The focus idea consists of a set of standalone modules, called wireless robotic components wireless robotic components (WRCs). Each component performs a particular function by means of a radio modem interface, a processing unit, and a sensor/actuator. The components interact through a coordinator that redirects asynchronous requests to the appropriate WRCs, configuring a built-in network. The WRC architecture has been tested in marine and terrestrial platforms to perform tasks of waypoint and wall following. Results show that the tested system complies with adaptability and portability that allow conforming a variety of autonomous vehicles.

Published: November 2020

AbstractBackground:A 10% prevalence of intracranial aneurysms in patients with coarctation of the aorta has been described in a few studies. Our objective is to describe the rate of intracranial aneurysm detection in patients with coarctation of the aorta in the current era. We hypothesise that, with earlier detection and coarctation of the aorta intervention, the rate of intracranial aneurysm is lower than previously reported and screening imaging may only be warranted in older patients or patients with certain risk factors.Methods:This is a retrospective study of 102 patients aged 13 years and older with coarctation who underwent brain computed tomography angiography, magnetic resonance imaging (MRI), or magnetic resonance angiography between January, 2000 and February, 2018.Results:The median age of coarctation repair was 4.4 months (2 days–47 years) and the initial repair was primarily surgical (90.2%). There were 11 former smokers, 4 current smokers, and 13 patients with ongoing hypertension. Imaging modalities included computed tomography angiography (13.7%), MRI (41.2%), and magnetic resonance angiography (46.1%), performed at a median age of 33.3 years, 22.4 years, and 25 years, respectively. There were 42 studies performed for screening, 48 studies performed for neurologic symptoms, and 12 studies performed for both screening and symptoms. There were no intracranial aneurysms detected in this study.Conclusions:These results suggest that the rate of intracranial aneurysms may be lower than previously reported and larger studies should explore the risk of intracranial aneurysms in coarctation of the aorta in the current era.

Authors: Watkins Stephanie , Freeborn Ellen , Mushtaq Sohail 
Published: November 2020

AbstractObjective:The aim of the present study was to develop and validate a vitamin D FFQ for assessment of dietary vitamin D intake in healthy adults in England, UK.Design:The current study assessed the agreement between a four-day food diary (4 d-FD) and a new vitamin D FFQ to measure dietary intake of vitamin D. Dietary intake was estimated using Nutritics dietary analysis software, and Spearman’s and Bland–Altman tests were utilised to assess correlation and agreement, respectively. Participants also provided a blood sample for plasma analysis of vitamin D concentrations.Setting:Home setting.Participants:Fifty participants were recruited to the study from the University of Chester and vicinity.Results:Results showed a strong correlation between vitamin D intake recorded by the FFQ and the 4 d-FD (r = 0·609; P < 0·0001) within 95 % limits of agreement. Furthermore, a significant correlation between plasma 25(OH)D concentrations and vitamin D intake measured by the FFQ (r = 0·290, P = 0·041) and the 4 d-FD (r = 0·360, P = 0·01) was observed.Conclusion:Our analysis suggests this FFQ is a useful and rapid tool for researchers and health professionals to assess vitamin D dietary intakes in healthy adults in the UK.
Viral surveillance and the 1968 Hong Kong flu pandemic
Authors: Peckham Robert 
Published: November 2020

AbstractThis article traces the diffusion of the 1968 Hong Kong influenza pandemic against the backdrop of scientific and global health developments, a global wave of social protests, and Cold War tensions between the United States and the People’s Republic of China. Although the outbreak was far less severe than the 1918–19 ‘Spanish’ influenza pandemic, the ease with which influenza spread globally between 1968 and 1970 contributed to a reformulation of global health that emphasized the need for enhanced preparedness and rapid vaccine production. From the 1950s through the 1960s, the scope of disease surveillance expanded, with China increasingly identified as the global epicentre of viral threats. In so arguing, the article challenges histories of global health that suggest that this was a period when concerns for infectious disease receded, in contrast to the final two decades of the twentieth century that saw the ascendancy of an ‘emerging diseases worldview’.
Germs, genomes, and global history in the time of COVID-19
Authors: Harper Kyle 
Published: November 2020

AbstractThe COVID-19 pandemic presents opportunities and challenges for historians working on the global history of health and disease. This article argues that the history of disease will benefit from interdisciplinary work that brings together historians, microbiologists, and archaeologists. Genomes are historical archives, in two complementary ways. Palaeogenomics provide direct access to genomes of the past, while phylogenetics furnish historical insight from evolutionary relationships. Both palaeogenomics and phylogenetics have already contributed enormously to the history of disease, helping us understand how human ecological transformation drives the evolution of our microparasites.

Published: November 2020

ABSTRACTThe Late Triassic fauna of the Lossiemouth Sandstone Formation (LSF) from the Elgin area, Scotland, has been pivotal in expanding our understanding of Triassic terrestrial tetrapods. Frustratingly, due to their odd preservation, interpretations of the Elgin Triassic specimens have relied on destructive moulding techniques, which only provide incomplete, and potentially distorted, information. Here, we show that micro-computed tomography (μCT) could revitalise the study of this important assemblage. We describe a long-neglected specimen that was originally identified as a pseudosuchian archosaur,Ornithosuchus woodwardi. μCT scans revealed dozens of bones belonging to at least two taxa: a small-bodied pseudosuchian and a specimen of the procolophonidLeptopleuron lacertinum. The pseudosuchian skeleton possesses a combination of characters that are unique to the clade Erpetosuchidae. As a basis for investigating the phylogenetic relationships of this new specimen, we reviewed the anatomy, taxonomy and systematics of other erpetosuchid specimens from the LSF (all previously referred toErpetosuchus). Unfortunately, due to the differing representation of the skeleton in the availableErpetosuchusspecimens, we cannot determine whether the erpetosuchid specimen we describe here belongs toErpetosuchus granti(to which we show it is closely related) or if it represents a distinct new taxon. Nevertheless, our results shed light on rarely preserved details of erpetosuchid anatomy. Finally, the unanticipated new information extracted from both previously studied and neglected specimens suggests that fossil remains may be much more widely distributed in the Elgin quarries than previously recognised, and that the richness of the LSF might have been underestimated.
Synthesis technique of a low-profile multiple sub-beam phased array antenna for high-throughput satellite applications
Authors: Sharifi Moghaddam Elham , Ahmadi Arash 
Published: November 2020

AbstractSub-beam concept is very useful for size reduction of multiple beam phased array antenna (PAA) systems that are applied for high-throughput communication satellites. In this paper, the synthesis procedure for a PAA with multiple sub-beams in two dimensions of the coverage domain is proposed and analyzed. In the design procedure, the interleaved sub-arraying technique has been applied to eliminate the grating lobes. The extremely short angular distance between adjacent sub-beams is challenging. An innovative beam forming network is proposed, which can generate multiple orthogonal sub-beams while keeping the required angular distance between sub-beams. To demonstrate the effectiveness of the design technique, an example considering the requirements derived from conceptual design of a high-throughput communication payload is presented. The array is optimized using the genetic algorithm while taking into account the technical requirements of the antenna. The gain patterns exhibit a 0.4° angular distance between adjacent sub-beams. In addition, the number of sub-arrays and element spacing guarantee the orthogonality of the sub-beams. The calculated carrier to interference ratio in the synthesized array shows that it has acceptable values in each spot. The aperture size reduction in the synthesized array compared to a conventional multiple beam array is more than 36.7%.

Abstract

Aims
Compared to their heterosexual peers, youth who identify as lesbian, gay or bisexual (LGB) tend to suffer higher rates of peer victimisation from bullying. However, studies of LGB adolescents' participation as bullies are scarce. We aimed to examine the possible association of sexual minority identity and the heightened risk of not only being bullied but bullying others as well. We also explored the effect of one's sexual identity on their involvement in bullying through the mediation of coping strategies and mood states.

Methods
A total of 12 218 students were recruited from 18 secondary schools in China. The demographic information, positive and negative coping strategies, mood state (anxiety, depression and hypomania) and information related to bullying and being bullied were collected. Multinomial regression was used to assess the heightened risk of sexual minority groups in comparison to their heterosexual adolescents' counterparts. A structural equation model (SEM) was used to test the mediating role of coping strategy and mood state between one's sex, sexual identity and bullying experience.

Results
Two trends could be observed: (1) LGB groups reported heightened risks of being bullied and bullying others at school than heterosexual peers. However, being a sexual-undeveloped girl seemed to have a protective effect on bullying-related problems. (2) Birth-assigned males were more likely to be bullied as well as bullying others at school when compared to birth-assigned females. SEM analysis revealed that being a sexual minority was directly associated with a higher frequency of being bullied (B = 0.16, 95% CI [0.10, 0.22], p < 0.001) but not bullying others (B = 0.02, 95% CI [−0.02, 0.06], p = 0.398) when compared to the heterosexual group. Negative coping, hypomania, anxiety and depression were associated with a higher frequency of being bullied, while positive coping was associated with a lower frequency of being bullied. Moreover, negative coping, hypomania and depression were associated with a higher frequency of bullying others, while positive coping was associated with a reduced likelihood of bullying others. In addition, being bullied and bullying others were significantly correlated in the SEM model.

Conclusions
This novel research investigated the dynamic nature of the interaction between victim and bullying of LGB school adolescents in China, with a specific exploration of the psychological mechanism behind the pattern of being bullied and bullying others. School-level interventions aimed at teaching positive coping strategies to lower psychological distress are recommended to support sexual minority students.
Collision‐Induced Absorption of CH4‐CO2 and H2‐CO2 Complexes and Their Effect on the Ancient Martian Atmosphere

Published: November 2020

AbstractExperimental measurements of collision‐induced absorption (CIA) cross sections for CO2‐H2 and CO2‐CH4 complexes were performed using Fourier transform spectroscopy over a spectral range of 150–475 cm−1 and a temperature range of 200–300 K. These experimentally derived CIA cross sections agree with the spectral range of the calculation by Wordsworth et al. (2017) however, the amplitude is half of what was predicted. Furthermore, the CIA cross sections reported here agree with those measured by Turbet et al. (2019, 2019). Additionally, radiative transfer calculations of the early Mars atmosphere were performed, and showed that CO2‐CH4 CIA would require surface pressure greater than 3 bar for a 10% methane atmosphere to achieve 273 K at the surface. For CO2‐H2, liquid water is possible with 5% hydrogen and less than 2 bar of surface pressure.
