Taxonomic implications of anatomical characteristics of the genus Tulipa (Liliaceae) in Turkey and their place in the historical subgeneric classifications
Authors: EKER İSMAİL , TANIŞ EZGİ 
Published: July 2022

This paper comprehensively discusses anatomical features of the genus Tulipa (Liliaceae) in Turkey. These are compared with the current subgeneric classification. Anatomical structures, including transverse sections of the root, stem (scape) and leaf, and surface sections of the leaves are illustrated based on the 420 preparations obtained from 42 OTUs (populations) belonging to 18 taxa. Densities of stomata and epidermis cells per unit leaf area (mm2), stomatal index and ratio of stomata index on the leaf surfaces were also calculated. Cluster and principal component analyses (PCA) were employed, and all results were compared at the population level. In this anatomical study, some significant differences were found among Tulipa taxa, especially at the infrageneric and interspecific levels. The results of anatomical investigations are consistent with published results of previous morphological and molecular analyses. The results of cluster analysis and PCA support the classifications of Veldkamp & Zonneveld and Christenhusz et al. including three subgenera, Eriostemones, Tulipa and Clusianae, but subgenus Orithyia was not included in this study because it is absent from Turkey. Subgenus Eriostemones is divided into two sections, Sylvestres and Saxatiles, following treatments by Baker and Eker et al. In subgenus Tulipa, although morphometric analyses partially supported the taxonomic grouping previously proposed as three separate sections, Tulipa, Tulipanum and Eichleres, it also clearly indicates that considering them as a single section (Tulipa) is perhaps a better option.

Abstract
A set of diagnostics based on simple, statistical relationships between precipitation and the thermodynamic environment in observations is implemented to assess phase 6 of the Coupled Model Intercomparison Project (CMIP6) model behavior with respect to precipitation. Observational data from the Atmospheric Radiation Measurement (ARM) permanent field observational sites are augmented with satellite observations of precipitation and temperature as an observational baseline. A robust relationship across observational datasets between column water vapor (CWV) and precipitation, in which conditionally averaged precipitation exhibits a sharp pickup at some critical CWV value, provides a useful convective onset diagnostic for climate model comparison. While a few models reproduce an appropriate precipitation pickup, most models begin their pickup at too low CWV and the increase in precipitation with increasing CWV is too weak. Convective transition statistics compiled in column relative humidity (CRH) partially compensate for model temperature biases—although imperfectly since the temperature dependence is more complex than that of column saturation. Significant errors remain in individual models and weak pickups are generally not improved. The conditional-average precipitation as a function of CRH can be decomposed into the product of the probability of raining and mean precipitation during raining times (conditional intensity). The pickup behavior is primarily dependent on the probability of raining near the transition and on the conditional intensity at higher CRH. Most models roughly capture the CRH dependence of these two factors. However, compensating biases often occur: model conditional intensity that is too low at a given CRH is compensated in part by excessive probability of precipitation.

Published: July 2022

Objectives: The incidence of type 2 diabetes in UK Black African and Caribbean communities is up to three times higher than in the general population, and engagement with self-management advice is poorer. This study explores the perspective of those living with diabetes to understand how the cultural salience of advice could be improved. Design: Participants were recruited via community venues, faith institutions and primary care. Eight focus groups were conducted with 41 individuals (Black African n = 23, Black Caribbean n = 18). Grounded theory methods were used for analysis. Results: Although motivated to manage the condition, individuals experienced a misalignment between elements of the care provision and cultural norms. Explanatory models of diabetes differed from the biomedical model reducing trust in treatment protocols. A lack of cultural salience reduced the accessibility of advice. Furthermore, elements of self-management advice were seen to conflict directly with some cultural traditions and practices. Individuals had to reconcile the two perspectives in order to proceed with self-management, often prioritising cultural norms and advice from informal sources over healthcare advice. Building personal relationships with the healthcare team improved trust and engagement. Conclusion: Findings suggest the needs in these communities were not being fully met. The healthcare interaction was pivotal in improving trust and engagement and reducing misinformation. However, appropriately informed community support also offers the potential to mitigate misalignment and to improve equity of access.

Published: July 2022

Background: Medical students are at a significant risk of experiencing psychological issues, such as burnout. Over the past few years, more studies have been conducted on this topic, producing different results. Aims: The purpose of this review was to determine the global pooled prevalence rate and risk factors associated with burnout and its components among undergraduate (pre-intern) medical students. Method: From inception until 30 November 2021, nine electronic databases were used for an electronic search. Using random-effects meta-analysis, we pooled the estimates using the DerSimonian-Laird method. The prevalence of burnout in medical students was the primary outcome of interest. Data were analyzed globally, by country, by research measure. Age and sex were examined as confounders using meta-regression analysis. Results: A random-effects meta-analysis of 42 studies involving 26,824 evaluating the prevalence of burnout in medical students showed an overall prevalence rate 37.23% [32.66%; 42.05%], Q = 2,267.15(41), p < .0001, τ2 = .42, τ = .65, I2 = 98.2%; H = 7.5. Prevalence of emotional exhaustion, depersonalization, and personal accomplishment were 38.08% [30.67%; 46.10%], 35.07% [26.74%; 44.41%], and 37.23% [32.66%; 42.05%], respectively. Variations were observed between countries and research measures. Age (older) and sex (female) were both significant predictors of burnout. Conclusion: The prevalence of burnout in medical students was estimated to be 37.23%. It is urgent that future studies serve as a basis for the development of prevention and treatment programs to prevent and treat burnout in students.

Published: July 2022

Objectives National data on the health of children and adolescents exposed to commercial sexual exploitation (CSE) are lacking, during both adolescence and adulthood. Using nationally representative data, we examined the health of male and female adolescents in grades 7-12 who experienced CSE exposure and subsequent adult health outcomes and access to health care. Methods Our retrospective cohort study used data from Waves I-IV of the National Longitudinal Study of Adolescent to Adult Health (1994-2008) to characterize relationships between CSE exposure before or during adolescence and health during adolescence and adulthood. The analytic sample included 10 918 adult participants aged 24-34 in Wave IV. We performed bivariate analyses, stratified by sex, to quantify the relationship between CSE exposure before or during adolescence and adolescent and adult health outcomes. Results Four percent of participants reported having a CSE exposure before or during adolescence (5% of males, 3% of females). Factors associated with CSE exposure among adolescents included race/ethnicity, parental education level, previous abuse, same-sex romantic attractions, history of ever having run away from home, and substance use. During adolescence, exposure to CSE was associated with worse overall health, depressive symptoms, and suicidal thoughts for both males and females. In adulthood, adolescent CSE exposure was associated with depression among males and functional limitations among females. A higher percentage of males with CSE exposure before or during adolescence, compared with their non–CSE-exposed peers, used the emergency department as their usual source of care during adulthood. Conclusions CSE exposure before or during adolescence was associated with poor adolescent and adult health outcomes and health care access. Observed differences between males and females warrant further exploration.

Published: July 2022

Objectives: Identifying children and adolescents within child welfare at risk for commercial sexual exploitation (CSE) can ensure referrals to appropriate services. However, screening measures to understand the prevalence of CSE are missing in child welfare. We evaluated the classification accuracy of a screener developed for the purpose of this study, guided by the Sexual Exploitation among Youth (SEY) risk assessment framework used in practice with child welfare–involved young people, (1) to identify young people at high versus low risk for experiencing CSE and (2) to estimate the prevalence of CSE risk for child welfare–involved children and adolescents. Methods: We used extant data from the National Survey of Child and Adolescent Well-being study with a nationally representative sample of children and adolescents aged 11-17 years (n = 1054) investigated by child welfare from February 2008 to April 2009. The 26-item screener showed acceptable reliability (α = .73) and test-criterion validity evidence using a CSE proxy outcome (ie, narrowly defined as being paid for sexual relations). We used the receiver-operating curve to classify risk and calculate the optimal cutoff score. Results: Higher scores on the SEY screener (range, 0-20 points) increased the odds of experiencing CSE by 34%. The screener was good at discriminating CSE risk at the 6-point cutoff, with 26.7% of child welfare–involved young people identified as being at high risk for CSE. Conclusions: Given the absence of accurate prevalence rates of CSE risk in the population, a theoretical cutoff index using an established method can provide an objective decision on how to distinguish risk levels. Prevalence estimates for CSE risk highlight the need for systematic screening in child welfare to identify and provide services for young people at risk.

Authors: Preble Kathleen M. , Nichols Andrea , Cox Ashley 
Published: July 2022

Objectives: While the needs of human trafficking survivors have been documented in the academic discourse, the saliency of such needs is understudied. This study aimed to reveal the critical needs of service provision for human trafficking survivors in a Midwestern state as perceived by multidisciplinary service providers. Methods: Targeting health care, social service, law enforcement, public health, and other service providers involved in anti–human trafficking service delivery, we disseminated a survey using purposive and snowball sampling. Drawing from survey responses collected in 2019 from 107 service providers working with 422 survivors of human trafficking in the previous 12 months in a Midwestern state, we examined the saliency of needs from the perspective of service providers in the health care, criminal justice, and social service sectors. Results: Respondents indicated on a Likert scale (1-5) the level of need for 37 social, health care, and legal services in their communities. The top-indicated needs statewide were mental health care, shelter/housing, peer mentorship programs, legal services, transportation, and provider training in juvenile courts, schools, law enforcement, and health care settings on human trafficking. Conclusion: The results suggest the need for statewide responses, such as legal assistance networks, telemental health options, and enhanced training collaborations between interpersonal violence and anti–human trafficking service providers. The study findings are generalizable beyond the study site in 3 ways that can guide strategic action: (1) they provide a framework for state-level analysis and strategic planning that parallels the results; (2) they show that regional variation is possible and should be accounted for in state-level study design, analysis, and strategic planning; and (3) the implications for housing assistance, legal assistance, mental health/substance use disorder–related health care, and training are scalable.
Use of ICD-10 Codes for Human Trafficking: Analysis of Data From a Large, Multisite Clinical Database in the United States
Authors: Kerr Patrick L. , Bryant Gavin 
Published: July 2022

Objectives: People experiencing trafficking often seek health care but are not identified. Although the Centers for Disease Control and Prevention added new International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes specific to human trafficking (hereinafter, HT ICD-10-CM codes) that could systematize the identification and documentation of human trafficking in US health care settings, the extent of their use is unknown. The objectives of this study were to investigate (1) the frequency of HT ICD-10-CM code use in US health care organizations (HCOs) and (2) demographic data associated with HT ICD-10-CM codes using a large clinical database. Methods: This retrospective study used deidentified data collected from October 1, 2018, through March 30, 2021, from a clinical database (N = 69 740 144 patients) network (TriNetX) of 48 collaborating US HCOs. Data included number of patients with ≥1 HT ICD-10-CM code, diagnoses, and demographic characteristics (age, sex, race, ethnicity, and region). Results: HT ICD-10-CM codes were associated with 298 patients in US HCOs, most of whom were young (mean [SD] age, 26 [16] y), White (53.0%; n = 158), and female (87.9%; n = 262). Thirty-seven of 48 (77.1%) participating HCOs used ≥1 HT ICD-10-CM code. The most frequently used HT ICD-10-CM codes were “forced sexual exploitation, suspected” (32.2%; n = 96) and “personal history of forced labor or sexual exploitation” (27.1%; n = 81). Labor trafficking codes were noted in approximately 3.7% of cases. Conclusions: HT ICD-10-CM codes are being used by health care professionals, as confirmed by large databases. Further research is needed to understand variation in code use and risk factors associated with human trafficking.
Analyzing the Relationship Between Psychological Biases and Initial Public Offerings Investment Decision-making in India
Authors: Singh Amit Kumar , Kumar Mohit 
Published: July 2022

The study investigates the effect of psychological biases on investment decision-making in the financial market with particular reference to the initial public offerings (IPO) market in India. The research is conducted by administering a self-completion questionnaire to measure selected psychological biases. Using the structural equation modelling (SEM) technique of the multivariate analysis, the study analyzes a sample of 230 individual IPO investors and examines the effect of the selected psychological biases on the degree of irrationality in the market. The findings of the study reveal that investors are prone to availability and representativeness biases. This study suggests that an augmented understanding of fundamental psychological biases of human decision-making would help the Indian IPO market achieve a more significant level of market efficiency. The contribution of this research lies in its practical implications to the issuer of the issue, intermediaries and market regulators. JEL Classification: G11, G23, G41
Linear Biases and Pandemic Communications
Authors: Villanova Daniel 
Published: July 2022

Background Previous research has demonstrated a tendency for individuals to mentally linearize nonlinear trends, leading to forecast errors. The present research notes that prior conceptualizations of these linear biases do not make identical predictions and examines how linear biases affect forecasts and risk perceptions of an unfolding epidemic. Methods This research uses an online experiment and a preregistered direct replication in a different online participant pool (total N = 608) to assess the trajectories of forecasts and risk perceptions over time in an unfolding epidemic. Results Framing the progress of the epidemic using total cases (v. the rate of new cases) leads to higher forecasts. This research also finds that the effect of frame varies over different time points in the epidemic and differs for forecasts versus risk perceptions. Finally, the effect of frame for forecasted totals is weaker among more numerate individuals. Limitations The studies use repeated measures that occur in 1 session rather than over the course of several months and involve a smooth epidemic curve rather than a noisy one with jagged case counts. Conclusions This research compares prior conceptualizations of linear biases and yields data with implications both for theory on linear biases and for communicators involved in disseminating information about epidemics. Highlights Framing the progress of the epidemic using total cases (v. the rate of new cases) leads to higher forecasts. The effect of frame varies over different time points in the epidemic and differs for forecasts v. risk perceptions. The effect of frame for forecasted totals is weaker among more numerate individuals.

Published: July 2022

Aims: The combination of biomaterial conductive scaffolds and electrical stimulation (ES) dramatically promotes stem cell differentiation into electro-responsive cells like neural cells. In this study, we aimed to fabricate PCL/PPY nanofiber scaffolds through the electrospinning method and investigate the effect of ES duration on neural differentiation of Conjunctiva Mesenchymal Stem Cells (CJMSCs). Methods: The topography of the fabricated scaffold was characterized using SEM and TEM microscopy, and its mechanical and other properties were determined by tensile, TGA, FTIR, and Contact angle tests. CJMSCs were seeded on the scaffolds and then subjected to electrical current (115 V m−1 at 100 Hz) with durations of 1, 3, and 7 min for 3 days. Then the effect of nanofiber scaffold and electrical currents on cell viability and expression of neural marker genes (Nestin, β-tubulin, MAP-2) was investigated by MTT assay and qPCR analysis. Results: Our results revealed the good biocompatibility of the PCL-PPy nanofiber scaffold, and according to q-PCR results, the electrical stimulation of 1 min day−1 for 3 days can induce neural differentiation of CJMSCs as indicated by the fold change of gene expression of Nestin (~127), B-tubulin (~30), and MAP-2 (~52). Conclusion: This study emphasizes that the utilization of an electrically conductive nanofibrous scaffold in conjunction with electrical current has potential applications in the field of neural tissue engineering.
Age Differences in Mental Health During the COVID-19 Pandemic: Assessing the Moderating Role of Attachment to God
Authors: Zhu Xi , Upenieks Laura 
Published: July 2022

Objectives: This study examined age differences in mental health problems (depression and anxiety) during the COVID-19 pandemic using nationally representative data from the United States. Drawing from a life course perspective, we also assessed if a secure attachment to God conditioned the relationship between age and mental health. Methods: Data were from the 2021 Values and Beliefs of the American Public Study ( N = 1168), collected roughly 1 year into the pandemic. Results: Older adults (61 years and over) reported lower depression and anxiety than respondents 18–30 years of age. However, stronger perceptions of attachment to God significantly closed the age gap in anxiety between these age groups. Discussion: Though absolute levels of religiosity tend to be higher for older adults, secure attachment to God was more protective of the mental health of younger adults during the pandemic. We reflect on our findings through a life course lens.
Comparative analysis of the aerodynamic performance of trains and dynamic responses of catenaries for windbreak walls with different heights under crosswind

Published: July 2022

Due to the deterioration of the crosswind-protection performance of the original earth embankment windbreak walls on the train with increased speed, researching the influence of the heightened windbreak walls on aerodynamic performances of trains as well as the protection of the catenary is necessary for optimizing the windproof performance. The improved delayed detached eddy simulation based on the shear stress transport (SST) κ-ω turbulence model was employed to simulate flow structures. Furthermore, the effect on the displacement of the catenary was investigated using the finite element method (FEM). The numerical case was validated against the field tests. The results show that the aerodynamic performances of the train were improved as the windbreak wall was heightened by 0.5 m. Whereas, further heightening the windbreak wall worsened the aerodynamic performance. When the windbreak wall was heightened by 0.5 and 1 m, the wind speed of the catenary was reduced by 31.17% and 53.87%, and the displacement of the catenary was reduced by 48.09% and 74.11%, respectively, compared with that of the original windbreak wall. These results reveal that the wind-protection performance on the train and catenary can be both improved by reasonably heightening windbreak walls.
