Published: December 2021

AbstractThis article proposes and demonstrates a new classification system of fish population level effects of hydropeaking operations in rivers. The classification of impacts is developed along two axes; first, the hydromorphological effect axis assesses the ecohydraulic alterations in rivers introduced by rapid and frequent variations in flow and water level, second the vulnerability axis assesses the site‐specific vulnerability of the fish population. Finally, the population level impact is classified into four classes from small to very large by combining the two axes. The system was tested in four rivers in Norway exposed to hydropeaking, and they displayed a range of outcomes from small to very large impacts on the salmon populations. The river with a relatively high base flow and ramping restrictions scored better than rivers with the lower base flow or limited ramping restrictions, indicating that hydropeaking effects can be mitigated while maintaining high hydropower flexibility. Most effect factors could easily be calculated from timeseries of discharge and water level, whereas the use of hydraulic models to estimate potential stranding areas may require more work. The vulnerability factors are mainly qualitative and depend more heavily on expert judgments and are thus more uncertain. The system was deemed suitable for the purpose of supporting management decisions for rivers exposed to hydropeaking operations. It evaluates the severity of the additional pressures due to hydropeaking operations and proved useful to identify mitigating measures. While the system was developed for Atlantic salmon river systems, it could be adapted to other species or systems.

AbstractThis is a mixed‐methods study of risk and resilience in a sample of over 14,000 students from 49 schools, assessed during the first 3 months of COVID‐19 in the United States. Over a third of students were of color and almost a third received financial aid. Participation rates were typically 90–99%. Overall, rates of clinically significant depression and anxiety were lower during distance learning in 2020 as compared to parallel rates documented during 2019, with a few exceptions. Hispanic students did not show reductions in depression rates, nor did gender non‐binary youth. Analyses of multiple risk and protective factors showed that in relation to depression, the most potent predictor was parent support, with effect sizes at least twice as high as those for any other predictor. Other robust predictors of depression included efficacy of learning online and concerns heard by school adults. In predicting to anxiety, parent support again had the largest effect sizes, followed by concerns heard at school, students’ worries about their futures, and worries about grades. In general, the absence of protective factors was more likely to be linked with high distress among youth of color than White students, and among girls and gender non‐binary students as compared to boys. At a policy level, the findings call for concerted attention to the well‐being of adults charged with caring for youth. Parents’ mental health has been increasingly threatened with the protracted stress linked with the pandemic. Thus, all avenues must be considered toward providing them with support—using feasible, community‐based interventions—as this is always the most important step in fostering children's resilience through adversity. Additionally, schools’ expectations about learning will have to be adjusted. As educators try to make up for academic losses during the pandemic, they must avoid high workloads detrimental for students’ mental health (and thus ability to learn). Finally, there must be ongoing institutional mental health support for teachers, counselors, administrators, and staff. Many of these adults have provided critical safety nets for youth since the start of the pandemic and are themselves at high risk for burnout. In conclusion, findings clearly show that if a central societal goal is to maximize resilience among youth through the continuing pandemic‐related challenges, we will have to deliberately prioritize an “upstream” approach, ensuring ongoing support for the adults who take care of them in their everyday lives.There must be ongoing institutional mental health support for teachers, counselors, administrators, and staff. Many of these adults have provided critical safety nets for youth since the start of the pandemic and are themselves at high risk for burnout.
Covid-19 and school closure: Examining the impact on private mid-range and low-fee private basic schools in Ghana
Authors: Juvenile Ehwi Lordina , Ehwi Richmond Juvenile 
Published: December 2021

AbstractThe Covid-19 lockdown implemented globally to prevent the spread of the virus has led to the closure of schools. However, insight into the impact of the lockdown on private schools and the responses it has elicited is limited, especially across the African continent. This article examines the impact of the lockdown on private basic schools in Ghana and how they responded to the closure. Following “organizational ambidexterity” and qualitative interviews with nine proprietors of private schools in Ghana, the study found that the schools’ closure had a negative impact on private basic schools in five crucial ways: disruption to teaching and learning, difficulty in retrieving unpaid teaching fees, inability to pay staff salaries and statutory payments, underutilization of existing assets, and the cost of storing unused stock. The article offers suggestions to the government to support private schools that are broadening educational access at thin profit margins.
Police Violence as Organizational Crime
Authors: Rich Sylvia 
Published: December 2021

AbstractThis paper argues that patterns of pervasive police violence can and should be treated as organizational crime in Canada. It uses the documented events of police violence in Val d’Or, Quebec, that emerged in 2015 to show how a similar fact pattern might fit all of the elements of organizational crime as defined in the Criminal Code. The article also suggests that this is an example where legal imagination is important, in order to shift our collective understanding of what organizational crime is and where it occurs.
Large eddy simulation of aircraft at affordable cost: a milestone in computational fluid dynamics

Published: December 2021

Abstract
While there have been numerous applications of large eddy simulations (LES) to complex flows, their application to practical engineering configurations, such as full aircraft models, have been limited to date. Recently, however, advances in rapid, high quality mesh generation, low-dissipation numerical schemes and physics-based subgrid-scale and wall models have led to, for the first time, accurate simulations of a realistic aircraft in landing configuration (the Japanese Aerospace Exploration Agency Standard Model) in less than a day of turnaround time with modest resource requirements. In this paper, a systematic study of the predictive capability of LES across a range of angles of attack (including maximum lift and post-stall regimes), the robustness of the predictions to grid resolution and the incorporation of wind tunnel effects is carried out. Integrated engineering quantities of interest, such as lift, drag and pitching moment will be compared with experimental data, while sectional pressure forces will be used to corroborate the accuracy of the integrated quantities. Good agreement with experimental

$C_L$

data is obtained across the lift curve with the coefficient of lift at maximum lift,

$C_{L,max}$

, consistently being predicted to within five lift counts of the experimental value. The grid point requirements to achieve this level of accuracy are reduced compared with recent estimates (even for wall modelled LES), with the solutions showing systematic improvement upon grid refinement, with the exception of the solution at the lowest angles of attack, which will be discussed later in the text. Simulations that include the wind tunnel walls and aircraft body mounting system are able to replicate important features of the flow field noted in the experiment that are absent from free air calculations of the same geometry, namely, the onset of inboard flow separation in the post-stall regime. Turnaround times of the order of a day are made possible in part by algorithmic advances made to leverage graphical processing units. The results presented herein suggest that this combined approach (meshing, numerical algorithms, modelling, efficient computer implementation) is on the threshold of readiness for industrial use in aeronautical design.
Gender bias in morphological inferences

AbstractThe present study explores how language learners apply gender stereotypes in learning a novel language with grammatical gender. Adult, English-speaking participants were exposed to picture–sound pairs from a miniature language. Each picture was of a matched gendered professional (e.g., male tennis player, female tennis player) with a nonsense form [CVCV-go/gu]. Participants were exposed to 32 picture–sound pairs (16 male, and 16 female, all matched) five times in a randomized order. Following training, participants were given a two-alternative forced-choice test with novel picture–word pairs. Participants were presented with a novel picture paired with two words (e.g., [befegu vs. befebo]) and were asked to choose which word most likely portrayed the meaning conveyed by the picture. These novel items contained gender-matched professions (e.g., male and female chemist), neutral items (office supplies), stereotypically female items (makeup), and stereotypically male items (tools). Participants assigned the appropriate gender to the novel professions, and assigned gender in line with the stereotyped objects at a rate significantly greater than chance (but not for neutral items). These results support the hypothesis that learning a language with a binary grammatical gender might be influenced by gender stereotypes.

Published: December 2021

AbstractBackgroundTo determine whether depressive symptoms in traumatic brain injury (TBI) patients were associated with altered resting-state functional connectivity (rs-fc) or voxel-based morphology in brain regions involved in emotional regulation and associated with depression.MethodsIn the present study, we examined 79 patients (57 males; age range = 17–70 years, M ± s.d. = 38 ± 16.13; BDI-II, M ± s.d. = 9.84 ± 8.67) with TBI. We used structural MRI and resting-state fMRI to examine whether there was a relationship between depression, as measured with the Beck Depression Inventory (BDI-II), and the voxel-based morphology or functional connectivity in regions previously identified as involved in emotional regulation in patients following TBI. Patients were at least 4 months post-TBI (M ± s.d. = 15.13 ± 11.67 months) and the severity of the injury included mild to severe cases [Glasgow Coma Scale (GCS), M ± s.d. = 6.87 ± 3.31].ResultsOur results showed that BDI-II scores were unrelated to voxel-based morphology in the examined regions. We found a positive association between depression scores and rs-fc between limbic regions and cognitive control regions. Conversely, there was a negative association between depression scores and rs-fc between limbic and frontal regions involved in emotion regulation.ConclusionThese findings lead to a better understanding of the exact mechanisms that contribute to depression following TBI and better inform treatment decisions.
Divine procreation of the world in Zoroastrian Pahlavi texts
Authors: Ahmadi Amir 
Published: December 2021

AbstractThere are two schemes of creation in Zoroastrianism. According to one, Ohrmazd fashions the world in the manner of a skilful craftsman. According to the second, Ohrmazd gestates and gives birth to the world. This article is about the latter. The relevant Pahlavi texts are presented and discussed. The article argues that Pahlavi authors used macrocosm-microcosm correspondence theory to elaborate the doctrine from Avestan rudiments.

Published: December 2021

Abstract

Introduction
Mini health technology assessment (HTA) reports have been used to support policy makers and health systems by providing a timely summary of scientific evidence. The objective of this meta-epidemiologic study was to evaluate the quality of reporting of mini-HTA reports published in Brazil.

Methods
An electronic search for all mini-HTA reports published between 2014 and March 2019 was conducted in the SISREBRATS and CONITEC databases. The study selection and data extraction were performed by two independent assessors. The following data were extracted: bibliographic data; research question; characteristics of the population, health technologies and outcomes assessed; eligibility criteria; information about searches and study selection; risk of bias assessment; quality of evidence assessment; synthesis of results; and recommendation about the technology evaluated. A descriptive analysis was used to summarize the information retrieved from all the included mini-HTA reports.

Results
We included 103 mini-HTA reports, the great majority of which (92.3 percent) focused on the coverage of the technologies in the healthcare system, with more than 60 percent being about drugs. Only five mini-HTA reports (4.8 percent) gave reasons for the choice of outcomes, and fifteen (14.5 percent) discriminated between primary and secondary outcomes. All mini-HTAs reported the databases searched and 99 percent of them reported using Medline. Sixty percent of the mini-HTA reported assessing the risk of bias, and 52 percent reported assessing the quality of evidence.

Conclusion
The quality of reporting of the mini-HTA reports performed in Brazil is insufficient and needs to be improved to guarantee transparency and replicability.

Published: December 2021

AbstractIntroduction:Education and training programs are critical to achieve personnel capacity building and professionalization in the rapidly growing humanitarian health sector. Thus, this study aimed to describe the status of humanitarian health education and training programs world-wide.Methods:A web-based analysis was conducted to identify the available humanitarian health programs. The following characteristics of the training programs were described: geographical location, target audience, prerequisite, qualification, curriculum, content, length, modality of delivery, teaching and assessment methods, and tuition fee.Results:The search identified a total number of 142 training programs, most of them available in few countries of the global North. Only seven percent of the identified programs qualified for a master’s degree in humanitarian health. Public health was the most identified content (47.2%). Approximately one-half of the training programs (50.7%) were delivered face-to-face. Theoretical knowledge was the most common method used for teaching and assessment. The duration of the training and tuition fees were different for different programs and qualifications, while target audience, prerequisite, and curriculum design were often vaguely described or missing.Conclusions:The study shows a global inequality in access to humanitarian health training programs due to financial and geographical constraints. The study also reveals gaps in program contents, as well as teaching and assessment methods, all issues that could be addressed by developing cost-effective e-learning and online simulation programs. Lastly, the data from this study provide a learning tool that can be used by humanitarian health educators and training centers to further define and standardize the requirements and competencies of humanitarian health professionals.
Power Struggles in the Implementation of Gender Equality Policies: The Politics of Resistance and Counter-resistance in Universities
Authors: Tildesley Rebecca , Lombardo Emanuela , Verge Tània 
Published: December 2021

AbstractThis article develops an analytical framework to study the power struggles between status quo and gender equality actors underpinning the implementation of gender equality policies. While resistance to gender equality policies in different institutions has received considerable scholarly attention, examining this struggle in light of a multifaceted concept of power that encompasses both domination and individual and collective empowerment, we argue, offers a more accurate account of the possibilities of a feminist politics of implementation. Our analytical framework also accounts for the factors that enable resistance by dominant actors and counter-resistance by gender equality actors and the informal rules that are being upheld or challenged, respectively. Applying our framework to the study of Spanish universities, we identify both the forms and types of resistance that hinder gender reform efforts in higher education institutions and the counter-action strategies that seek to drive implementation forward and achieve institutional change.
Estimation of Specific Yield for Regional Groundwater Models: Pitfalls, Ramifications, and a Promising Path Forward

Published: December 2021

AbstractSpecific yield (Sy) is one of the most important aquifer parameters in groundwater models with large storage changes. However, it has received limited attention from the modeling community and there are few, if any, approaches that can be widely applied for determination of Sy at the scale required for regional aquifer studies. Despite the limitations of parameter estimation methods and of direct measurements of aquifer storage properties in the field, the large uncertainty in model Sy values is typically ignored and Sy is incorrectly assumed to be a known quantity. These practices can introduce errors into model predictions of aquifer budget components, such as recharge and storage depletion. In turn, aquifer management and planning can be greatly impacted, as estimates of aquifer responses to pumping changes are highly dependent on those simulated budget components. In this work, we use a groundwater model of a portion of the High Plains aquifer in the central United States to illustrate the impacts of inappropriately large Sy values on model predictions and the related water management ramifications. Building on our recent work, we propose a data‐driven approach for determining specific yield for regional groundwater models. Results demonstrate that this new approach can improve model reliability and lead to more robust predictions of aquifer responses to management scenarios.
Availability of ultrasound imaging of a guidewire parallel to the vein during internal jugular central venous catheter placement
Authors: Wakabayashi Ryo 
Published: December 2021

AbstractUltrasound verification of the guidewire traveling along the vein parallel to it and without any changes in angle has been recommended for prevention of inadvertent arterial catheterization during central venous catheter (CVC) placement. The aim of this study was to determine the availability of this parallel guidewire imaging during internal jugular CVC placement. Fifty-six adult patients undergoing cardiovascular surgery were included. The success rate of acquiring a parallel guidewire image was assessed. Logistic regression models and generalized additive models were used to identify the factors contributing to achieve parallel guidewire imaging. Among 56 patients in whom the guidewire was correctly positioned, the parallel guidewire image was acquired in 45 (80%) patients. Body mass index (crude odds ratio: 0.74 [95% confidence interval: 0.61–0.91]; p = 0.004) and distance from the puncture site to the clavicle (crude odds ratio: 1.32 [95% confidence interval: 1.11–1.58]; p = 0.002) were associated with successful depiction. The predicted probability of successful visualization was 96% (95% confidence interval: 82–99%) when the distance from the puncture site to the clavicle was 50 mm. The distance is a reliable predictor for successful visualization, and thus it should be considered when performing internal jugular CVC placement.
Hypochromic red cells as predictors of anemia in patients undergoing hemodialysis: an observational retrospective study

Published: December 2021

AbstractThe percentage of hypochromic red blood cells (%HRC) estimates the availability of iron by evaluating the degree of hemoglobinization. We investigated whether %HRC was a predictor of anemia in patients undergoing hemodialysis. We recruited 142 patients undergoing routine hemodialysis between 2017 and 2019. Delta hemoglobin level (ΔHb)1mo-baseline was calculated as the difference between the hemoglobin level at 1 month after study enrollment and that at the time of study enrollment. Development of anemia was defined as hemoglobin level ≤ 15% of baseline. The median %HRC was 3.1%. There was a significant negative correlation between (ΔHb)1mo- baseline and %HRC (r =  − 0.63, P < 0.001). The incidence of anemia was significantly higher in patients with %HRC > 3.1% than in those with %HRC ≤ 3.1%. In the multivariate logistic regression analysis, %HRC was significantly related to the development of anemia (odds ratio 2.57, 95% confidence interval [CI] 1.72–3.85, P < 0.001). The best cutoff value for %HRC to predict the development of anemia was 4.3%, with a sensitivity and specificity of 67.74 (95% CI, 54.7–79.1) and 97.50 (95% CI, 91.3– 99.7), respectively. %HRC is an independent predictor of anemia in patients undergoing hemodialysis. %HRC ≤ 4.3% is an early marker to consider changing the anemia treatment.
