Abstract
Background
During any critical health care situation as COVID-19 pandemic, it is expected that the medical staff will be under a high level of stress. However, nurses specifically are under both physical and psychological pressure during this pandemic, with a risk of mental health problems, such as anxiety and depression. Accordingly, nurses exposed to patients with COVID-19 infection are expected to suffer from a high level of depressive symptoms. This cross-sectional study was applied on 456 nurses with age ranges from 18 to 60. They were divided into two groups: group 1 were composed of 228 nurses who were directly exposed to suspected or confirmed cases of COVID-19 patients, while group 2 were composed of 228 who were less exposed to suspected or confirmed cases of COVID-19 patients for comparison. Data were collected by personal interviews with nurses using Patient Health Questionnaire 9 (PHQ 9) scale for assessment of presence of depressive symptoms and its severity. We aimed to assess the both the prevalence and the predictors of depressive symptoms among nurses exposed to COVID-19 patients.

Results
We found a statistically significant higher percentage of depressive symptoms among nurses directly exposed to COVID-19 patients (61.8%) versus the less exposed group (18%). There was a statistically and significantly higher specific COVID-19 associated stressors score (SCAS) among nurses directly exposed to suspected or confirmed cases of COVID-19 patients compared to those who were less exposed; likewise, the PHQ-9 score was a statistically and significantly higher among directly exposed group compared to less-exposed group. Moderate and severe depressive symptoms were present in 23.2% and 22.4%, respectively, within the group of nurses with direct exposure; meanwhile, the less-exposed group showed 7.5% and 3.9%, respectively, with statistically higher significant difference. On doing a linear regression analysis, all the following predictors were significantly independently associated with higher PHQ-9 scores (with higher depressive symptoms severity) among nurses exposed to COVID-19: physical isolation (restrictions on touching others, even after working hours), exposure to a new COVID-19 patient, developing COVID-19-like symptoms, displaying COVID-19-like symptoms by colleagues, knowing that COVID mortality rate exceeds influenza, possible separation from family, concern about family members, fears about infection for patients, family, and friends.

Conclusions
COVID-19 pandemic has serious effects on the psychological well-being of nurses exposed to COVID-19 patients. There was an increased rate of depressive symptoms among them during the pandemic with its subsequent burden. Therefore, nurses exposed to COVID-19 patients are in a high need of care and support during the pandemic.

Abstract
As known, the piezoelectric polarization effect makes GaN HEMT have unique electrical characteristics and wider applications compared with other III-V semiconductor devices. In this letter, a novel electromechanical coupling theory is proposed and verified for the first time for the GaN HEMT heterojunction structure by applying the mechanical clamping boundary conditions in piezoelectric constitutive equations. The total piezoelectric polarization defined as P
couple in this new electromechanical coupling theory consist of three parts: the spontaneous polarization P
sp, the strain-induced piezoelectric polarization P
strain due to lattice mismatch in growth, and the bias-dependent piezoelectric polarization

. The output and transfer characteristics of GaN HEMT have been simulated based on the new electromechanical coupling theory and verified in agreement with the experimental results in trend. This theory helps to extend the understanding of the basic physical mechanism of the AlGaN/GaN interface and is of great significance to device design and application for GaN-based materials.
Genome-wide association studies (GWAS) for orthopedic diseases: a systematic review
Authors: Sadat-Ali Mir 
Published: January 2023

Background and Objective: The objective of this review is to examine genome-wide association studies (GWAS) and whether they have helped treat orthopedic diseases in general and in the Middle East in particular. Methods: Between 2005 and May 2022, we searched MEDLINE, Scopus, Web of Science, EMBASE, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews and the Science Citation Index. Our criteria for manuscript analysis included articles involving patients with the presence or absence of the gene and single nucleotide polymorphism (SNP) that were published in the English language. The exclusion criteria included review articles and correspondence. We reviewed all of the articles manually for risk of bias and found no discrepancies in the papers selected. Results: There were 53,652 GWAS articles that reported on the Human Genome Project, out of which 439 studies reported on orthopedics. In total, 38 studies with data from 1,489,834 patients was analyzed. Conclusions: We identified many novel loci that can cause disease processes. We expected these studies to help in predicting diseases and developing new diagnostic procedures, preventive strategies, and better clinical care; however, this has not happened yet. It appears that we must investigate further before translating this knowledge in patient care.

Background: The World Health Organization (WHO) recommends seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine and amodiaquine for children aged 3 to 59 months, living in areas where malaria transmission is highly seasonal. However, due to widespread prevalence of resistance markers, SMC has not been implemented at scale in East and Southern Africa. An initial study in Uganda showed that SMC with SPAQ was feasible, acceptable, and protective against malaria in eligible children in Karamoja region. Nonetheless, exploration of alternative regimens is warranted since parasite resistance threats persist. Objective: The study aims to test the effectiveness of SMC with DP or SPAQ (DP-SMC & SPAQ-SMC), chemoprevention efficacy as well as the safety and tolerability of DP compared to that of SPAQ among 3-59 months old children in Karamoja region, an area of Uganda where malaria transmission is highly seasonal. Methods: A Type II hybrid effectiveness-implementation study design consisting of four components: 1) a cluster randomized controlled trial (cRCT) using passive surveillance to establish confirmed malaria cases in children using both SPAQ and DP; 2a) a prospective cohort study to determine the chemoprevention efficacy of SPAQ and DP (if SPAQ or DP clears sub-patent infection and provides 28 days of protection from new infection) and whether drug concentrations and/or resistance influence the ability to clear and prevent infection; 2b) a sub study examining pharmacokinetics of DP in children between 3 to <6 months; 3) a resistance markers study in children 3–59 months in the research districts plus the standard intervention districts to measure changes in resistance marker prevalence over time and finally; 4) a process evaluation. Discussion: This study evaluates the effects of a clinical intervention on relevant outcomes whilst collecting information on implementation. Conclusion: This study will inform malaria policy in high-burden countries and contribute to progress in malaria control.

Published: January 2023

HighlightsSteam gasification parameters of cattle manure char were optimized.Effects of slow heating and fast heating modes on char gasification were analyzed.1.92 m3/kg syngas yield and 88.72% C-conversion efficiency were obtained at 850 °C, with fast heating, 1.66 g/min of steam flow rate, and K2CO3 catalyst.Abstract. This study investigated the hydrogen-rich gas production from cattle manure char by steam gasification. The characteristics of char were studied by proximate analysis, ultimate analysis, thermogravimetric analysis, and XRD analysis. The effects of temperature, heating mode, steam flow rate, and catalyst on syngas yield, hydrogen yield, gas composition, heating value, and carbon conversion efficiency were explored. The results showed that the fixed carbon content in cattle manure char was 34.46%, an increase of 2.24 times compared with that of cattle manure, and the cattle manure char had a high fixed carbon content and thermal stability. The steam gasification indicated that the high temperature and fast heating could obtain high syngas and hydrogen yields. The steam flow rate played an important role in the char and steam reforming reactions. The SiO2 and ash catalysts had an inhibitory effect on the steam gasification of char. However, the K2CO3 catalyst improved the syngas and hydrogen yields. The optimal parameters in this study were 850 °C, fast heating, 1.66 g/min of steam flow rate, and K2CO3 catalyst. By comparison, the syngas and hydrogen production of char were better than those of biomass. As a result, the steam gasification of char was a promising method for producing hydrogen-rich gas.

Effects of Livestock Exclusion on Pollutant Export From a North Carolina Beef Cow Pasture
Authors: Line Daniel E. , Doll Barbara 
Published: January 2023

HighlightsExclusion of beef cattle from two streams resulted in significant reductions in nitrogen, phosphorus, and sediment exports.Reductions in nutrient and sediment export improved following four or more years of exclusion.Nitrogen and phosphorus concentrations in storm samples decreased more than those in baseflow samples.Abstract. Fences were installed to exclude cattle from two adjacent small streams on a beef and swine farm located in central North Carolina. The two streams, referred to as UTA and North, originated in a pasture used for beef cow production and the application of swine waste. Rainfall and discharge were continuously monitored for 1.34 years prior to and 1.8 years after the fencing was installed in order to quantify the effect of the livestock exclusion on pollutant export/loads in the two streams originating in the pasture. Monitoring results documented reductions in total nitrogen (TN), phosphorus (TP), and total suspended solids (TSS) exports via the North stream of 15%, 54%, and 67%, respectively. Monitoring on the UTA stream was restarted 3.7 years after the initial 1.8 years and continued for about 1 year to assess the effect of natural vegetation growth and stream channel soil recovery. The combined reductions for the two periods were 39%, 64%, and 74% for TN, TP, and TSS, respectively. Exports of TN, TP, and TSS during the later monitoring period decreased by 13%, 60%, and 22%, respectively, compared to the initial 1.8-year monitoring period. These results indicated that exclusion fencing was effective at reducing pollutant exports during the first 1.8 years and that its effectiveness increased after about four years. Consequently, studies that report effectiveness during the first 2 to 4 years after exclusion likely underestimate the long-term effectiveness of the exclusion fencing.

Quenching measurements of Kr 5p[3/2]2 ← ← 4p6
1S0 electronic transition using absorption spectra

Published: January 2023

Quenching rate is an important parameter to include in fluorescence
measurements that are aimed at quantifying the thermochemical field of
a reacting flow. Traditionally, the quenching measurements were
obtained at low pressures using the direct measurements of quenching
times followed by a linear scaling to the desired pressure. This
approach, however, cannot account for the possible deviation from the
linear pressure scaling at elevated pressures due to three and
multi-body collisions. Furthermore, the best accuracy on the quenching
rate is obtained with ultra-short pulse lasers that are typically not
readily available. This study offsets these limitations by
demonstrating a new approach for making direct quenching measurements
at atmospheric conditions and using nanosecond lasers. The quenching
measurements are demonstrated in a krypton-perturber system, and the

accessed. A theoretical construct is presented that relates the
absorption spectral parameters and the integrated fluorescence signal
to the quenching rate, referenced to a given species and conditions.
Using this formulation, the relative quenching rates for different

measurement of the relative quenching rate, unlike the previous
studies where absolute quenching rates are measured. Nonetheless, when
the reference quenching rate is independently measured, the relative
quenching rates can be converted to absolute values.
A Changing Culture? An Exploration of Data Sharing in the Humanities
Authors: Grant Rebecca , Cannon Matt , McKellar Kate 
Published: January 2023

This poster will present preliminary results from a survey of humanities authors, and interviews with editors of humanities journals, which aimed to explore their attitudes towards, and knowledge of research data sharing.
Although academic publishers are increasingly adopting data sharing policies across their journal portfolios, many policies are drafted to reflect scientific research outputs rather than those from the humanities or social sciences. Researchers in the humanities may find compliance with such policies challenging, and struggle to identify what constitutes their “research data” and how it can be shared appropriately.
As part of the STM Association’s Research Data Program, a group representing seven academic publishers (Taylor & Francis, SAGE, BRILL, Oxford University Press, Wiley, F1000 and Cambridge University Press) have come together to discuss how data sharing by authors in humanities journals can be supported and encouraged.
The group developed an online survey to identify which aspects of data policy compliance researchers find most challenging; and in parallel, conducted a series of interviews with editors to discuss the impacts of data sharing policies on their journals. The results presented will address questions including “What is humanities data?” and “Do humanities researchers perceive journal data sharing policies negatively, or positively?”
AI and Peer Reviewer Selection
Authors: Selonick Lillian Wang , Gupta Saumya , Pajerowski Jennie 
Published: January 2023

In a recent study by Hamilton (2020), of 196 surveyed journal editors, only 35% reported satisfaction with their journal’s peer review process. They named, among other challenges, difficulty recruiting reviewers as one desired area of improvement. Publishers, meanwhile, have shown an interest in diversifying their author, editor, and reviewer pools, as evidenced by the proliferation of webinars, committees, projects, and coalitions dedicated to increasing Diversity, Equity, and Inclusion—notably, C4DISC, the Royal Society of Chemistry’s Joint Commitment, last year’s Peer Review Week theme of Identity in Peer Review, and the many excellent posts on the Scholarly Kitchen that address this topic. In recent years, companies like Clarivate and Unsilo have introduced AI-driven tools that claim to meet the editors’ need by suggesting relevant reviewers. In this poster, we will explore the viability of using these and similar technologies to improve the diversity of reviewer pools by connecting editors with reviewers outside of their usual professional networks. These technologies are exciting, but have the potential to perpetuate existing biases. Artificial intelligence has the potential to improve the peer-review system; however, Checco et al. (2021) found major pitfalls and implications of using AI tools in terms of biases and ethics.
To what extent can technology counterbalance human bias by suggesting early career, non-male, or international reviewersü What biases might an AI-driven reviewer search replicate, and can they be avoidedü How do design choices by submission management systems affect an editor’s reviewer selection processü Are there problems that can’t be solved by techü
Smarter Business Intelligence for the Open Access Era: The Advanced Analytics You’re Probably Not Using for Your Editorial, Sales, and Plan S Strategies
Authors: Groth Mike , Beyer Tom , Maxwell Stuart 
Published: January 2023

Beyond basic COUNTER compliance, many societies and independent publishers struggle to turn platform and usage analytics into action, especially for Open Access content. From measuring the performance of their publications to guiding editorial strategy to uncovering revenue opportunities, scholarly publishers often don’t avail themselves of all the measurable data or know how to use it to make informed business decisions. Add to that the problems of unauthenticated and unidentified OA usage, the indeterminate status of transformative journals, and the onerous reporting requirements of Plan S, and publishers can easily find themselves in a state of analysis paralysis.
Fortunately, there are many resources already at your disposal and supplemental supports to help academic book and journal publishers connect the dots, fill in the OA gaps, and make sense of raw data to turn it into actionable business intelligence. KGL PubFactory’s Tom Beyer will give an overview of publishing analytics from essential reports to advanced custom metrics using granular data, to emerging capabilities and prerequisites for tracking and reporting OA content. Joined by a publisher who will describe specific use cases, the authors will cover the latest advances in business analytics and unique data problems experienced by our industry. Together we will aim for a higher intelligence—no matter what business model—to better serve our users and the research community.
Foreign language teacher grit: scale development and examining the relations with emotions and burnout using relative weight analysis
Authors: Soleimanzadeh Soheila , Khajavy Gholam Hassan , Barabadi Elyas 
Published: January 2023

Abstract
As teaching a foreign language (FL) is a demanding and frustrating career, FL teachers might face different challenges and difficulties which in turn would lead them to quit their jobs. Therefore, FL teachers need to keep their effort, energy, and passion to achieve their teaching goals. FL teacher grit (i.e., perseverance of effort and consistency of interest in FL teaching) is the concept that deals with these issues. In this study, we developed a new FL teacher grit scale (FLTGS) and investigated how FL teacher grit is related to their burnout and different discrete emotions. To this end, a total of 235 FL teachers filled out the questionnaires. The results of the study indicated, firstly, that the newly developed FL teacher grit scale had high reliability and a two-factor model fitted the data adequately. Secondly, findings indicated that both grit components had positive correlations with FL teaching enjoyment and negative correlations with FL teaching anxiety, boredom, and burnout. Finally, the results of relative weight analysis showed that FL teacher grit components can be as important as emotions in predicting burnout. Our findings suggested that the newly developed grit scale could provide us with a valid and reliable tool to assess FL teacher grit. Moreover, our findings suggested that higher levels of FL teacher grit can prevent them from experiencing burnout.

Abstract
The absorption, distribution, and transport trends of organic and inorganic arsenic (As) in honesuckle (Lonicera japonica) were studied using synchrotron X-ray fluorescence spectroscopy (μ-XRF). The root, stem, and leaf samples were analyzed by μ-XRF, proving that in the presence of dimethyl arsenate acid, a small amount of As accumulated in local areas of the epidermis and cortex of roots, while most of As migrated to the upper plant through the middle vascular column. After reaching the stem, As was mainly distributed in the outer skin, indicating that the root and stem of L. japonica blocked the transport of As in the plant. In the presence of As(iii), A large amount of As accumulated in the epidermis and cortex of the root, reducing its further transport from the plant roots. Once As entered the stem of L. japonica from the root, it achieved a strong transport capacity, thus causing severe harm to plants. The element correlation analysis revealed that As in L. japonica had the strongest correlation with Cu and Zn elements, for the future research on the influence of As pollution on plants, the interference based on the above two elements can be considered.
