Authors: Álamo Mercedes , Falla Daniel 
Published: March 2023

Los estudios han evidenciado que un liderazgo transformacional favorece la innovación, el cambio e implicación hacia la mejora y resolución de problemas, generando una atmósfera de respeto y tolerancia y considerándose un liderazgo idóneo en el ámbito educativo. Asimismo, las competencias socioemocionales y morales son esenciales en los líderes y docentes de los centros escolares. Sin embargo, existe una brecha sobre qué tipo de competencias socioemocionales y morales pueden relacionarse con un estilo de liderazgo transformacional en futuros docentes y que podría ser una información relevante para la formación universitaria, siendo este el propósito de este trabajo. Para esta investigación ex post facto de corte cuantitativo a través de encuesta se contó con una muestra de 395 futuros docentes (81.3% mujeres y 18.7% hombres) entre 17 y 63 años (M = 21.08; DT = 3.49. Los análisis estadísticos incluyeron la prueba t de Student y regresiones lineales. Los resultados mostraron puntuaciones elevadas en liderazgo transformacional y un alto grado en competencias socioemocionales y morales. Se hallaron diferencias significativas en sexo, de forma que las chicas presentaron puntuaciones más altas. Se encontró relación entre la autogestión y motivación, conciencia social y conducta prosocial, toma de decisiones responsables y emociones morales con liderazgo transformacional. Se discute las implicaciones prácticas de estos hallazgos y se concluye señalando la importancia del trabajo y fomento de las competencias socioemocionales y morales en futuros docentes dentro de su formación universitaria para favorecer un liderazgo transformacional que facilite una mejor dirección en los centros educativos.

Abstract
The study investigates the effect of capital inflows and institutional quality on economic growth in eight oil exporting African countries using FGLS and AMG methods to analyse the data spanning from 1996 to 2020. It was observed that foreign direct investment, external debt and official development assistance present no significant influence on economic growth. Institutional quality has a positive and significant influence on economic growth. When institutional quality was interacted with the various capital inflows, it only had influence on external debt as the interaction between institutional quality and external debt revealed a significant effect but did not spur economic growth. The study therefore concluded that capital inflows have no effect on economic growth. Consequently, the study recommends that, for oil exporting African countries to reduce the risks and uncertainties inherent with foreign direct investment, good institutions must be set up and made to work, long-term economic growth and fiscal and debt sustainability must be emphasized, and finally, aid should be provided based on achieved policy levels rather than promises of improvement in order to boost foreign aid effectiveness.

Published: March 2023

Abstract
Background: Artemisia selengensis, a perennial herb of the genus Artemisiain the family Asteraceae, has both edible and medicinal values. There are few studies on the chloroplast genome of Artemisia selengensis, and the phylogeographic classification is vague, which makes phylogenetic analysis and evolutionary studies very difficult.
Results: The chloroplast genomes of 10 Artemisia selengensisin this study were highly conserved in terms of gene content, gene order, and gene intron number. The genome lengths ranged from 151,148 to 151,257 bp and were typical of a quadripartite structure with a total GC content of approximately 37.5%. The chloroplast genomes of all species encode 133 genes, including 88 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Due to the contraction and expansion of the inverted repeats (IR), the overlap of ycf1and ndhF genes occurred at the inverted repeats B (IRB) and short single copy sequence (SSC) boundaries. According to a codon use study, the frequent base in the chloroplast genome of Artemisia selengensis' third codon position was A/T. The number of SSR repeats was 42-44, most of which were single nucleotide A/T repeats. Sequence alignment analysis of the chloroplast genome showed that variable regions were mainly distributed in single copy regions, nucleotide diversity values of 0 to 0.009 were calculated by sliding window analysis, eight mutation hotspot regions were detected, and coding regions were more conserved than non-coding regions. Analysis of non-synonymous substitution (Ka) and synonymous substitution (Ks) revealed that accD, rps12, petB, and atpF genes were affected by positive selection and no genes were affected by neutral selection. Based on the findings of the phylogenetic analysis, Artemisia selengensis was sister to the genus Chrysanthemumand formed a monophyletic group with other Artemisia genera.
Conclusions: In this research, the present study systematically compared the chloroplast genomic features of Artemisia selengensis and provided important information for the study of the chloroplast genome of Artemisia selengensis and the evolutionary relationships among Asteraceae species.
Maternal exposure to metal components of PM2.5 and low birth weight in New Mexico, USA

Abstract

Infants with low birth weight (LBW) are more likely to have health problems than normal weight infants. In studies examining the associations between particulate matter (PM) exposures and LBW, there is a tendency to focus on PM2.5 as a whole. However, insufficient information is available regarding the effects of different components of PM2.5 on birth weight. This study identified the associations between maternal exposure to 10 metal components of PM2.5 and LBW in offspring based on small area (divided by population size) level data in New Mexico, USA, from 2012 to 2016. This study used a pruned feed-forward neural network (pruned-FNN) approach to estimate the annual average exposure index to each metal component in each small area. The linear regression model was employed to examine the association between maternal PM2.5 metal exposures and LBW rate in small areas, adjusting for the female percentage and race/ethnicity compositions, marriage status and educational level in the population. An interquartile range increase in maternal exposure to mercury and chromium of PM2.5 increased LBW rate by 0.43% (95% confidence interval (CI): 0.18%-0.68%) and 0.63% (95% CI: 0.15%-1.12%), respectively. These findings suggest that maternal exposure to metal components of air pollutants may increase the risk of LBW in offspring. With no similar studies in New Mexico, this study also posed great importance because of a higher LBW rate in New Mexico than the national average. These findings provide critical information to inform further epidemiological, biological, and toxicological studies.
Invasive freshwater snails are less sensitive to population density than native conspecifics.
Authors: Najev Briante Shevon Lewis , Neiman Maurine 
Published: March 2023

Abstract
Species invasion can negatively affect natural ecosystems by causing biodiversity loss, changing nutrient cycling processes, and altering trophic webs. Understanding how and why some species or lineages become invasive is critically important to preventing and controlling invasions. We address whether key life history traits of invasive vs. native lineages – here Potamopyrgus antipodarum - differ in response to environmental stressors that could determine the outcome of invasions. We focus here on population density, which is a fundamental characteristic of all populations and to which native lineages of P. antipodarum are very sensitive. This New Zealand freshwater snail successfully invaded Europe in the 19th century and is a more recent invader in North America. In just a few decades, invasive populations of P. antipodarum have spread across much of North America, with detrimental effects for local food webs and native species. We quantified individual growth rate and embryo number in P. antipodarum from multiple distinct native range and invasive lineages cultured from the juvenile stage across three different population density treatments. The growth of native but not invasive lineages decreased as density increased, and reproduction in invasive but not native snails was positively affected by increased density. These results are consistent with a scenario where differential sensitivity to population density could help explain why some lineages become invasive while others do not. Our findings also align with previous studies that show that invasive lineages of P. antipodarum exhibit a relatively wide range of tolerance to environmental stressors.

Published: March 2023

Abstract
Background
Methamphetamines (MA) are a frequently used drug class with potent sympathomimetic properties that can affect cerebral vasculature. Conflicting reports in literature exist about the effect of exposure to MA on vasospasm risk and clinical outcomes in aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to characterize the impact of recent MA use on the timing, severity and features of vasospasm in aneurysmal subarachnoid as well as neurological outcomes.
Methods
We retrospectively screened 441 consecutive patients admitted to a tertiary care hospital with a diagnosis of SAH who underwent at least one cerebral digital subtraction angiogram (DSA). Patients were excluded if no urinary toxicology screen was performed within 24 hours of admission, if there was a diagnosis of non-aneurysmal SAH, or if ictus was greater than 72 hours from hospital admission. Vasospasm characteristics were collected from DSA and transcranial doppler (TCD) studies and demographic as well as clinical outcome data was abstracted from the chart.
Results
129 patients were included and 24 tested positive for MA. Among the 312 excluded patients, 281 did not have a urinary toxicology screen and 31 had a non-aneurysmal pattern of SAH or ictus occurring greater than 72 hours from hospital admission. No significant differences were found in respect to patient age, sex, or admission Hunt and Hess Score or Modified Fisher Scale based on MA use. There was no difference in the severity of vasospasm or time to peak severity using either TCD or DSA criteria on multivariate analysis. Aneurysms were more likely to be in the anterior circulation for both groups, however the MA cohort experienced less vasospasm involving the anterior circulation and more isolated posterior circulation vasospasm. There was no difference in delayed cerebral ischemia (DCI) incidence, length of ICU stay, need for ventriculoperitoneal shunt placement, functional outcome at discharge or hospital mortality.
Interpretation:
Recent MA use was not associated with worse vasospasm severity, time to vasospasm, or DCI in aSAH patients. Further investigations about localized MA effects in the posterior circulation and impact on long-term functional outcomes are warranted.
Global urbanization benefits food security and nature restoration

Published: March 2023

Abstract
Urbanization has been considered as an antagonist to food security and nature restoration due to land-taking by urban expansion. However, if urbanization was undertaken with a focus on integrated urban–rural development, it could in face release land areas globally. Here show that domestic rural-to-urban migration with urbanization can support a global population with 2 billion more people, while requiring 49 million hectares of less built-up lands due to higher population density in urban relative to rural areas, over the period from 2020 to 2050. If no urbanization would occur, currently predicted growth trends in global population would require an additional 46 million hectares of lands. If cross-countries rural-to-urban migration is supported, land release could be increased up to 67 million hectares. This amount could satisfy 51% of global cropland demand in 2050, and as an additional benefit, reduce cropland fragmentation. If the land areas released were set aside for nature restoration, 4,488 more species could be protected. As a further co-benefit, additional carbon sequestration of 15 billion tonnes could be achieved over the period from 2020 to 2050. Policies to promote cross-countries rural-to-urban migration and management of released lands would help to benefits food security and natural restoration.
Energy harvesting of flow induced vibration enhanced by bionic non-smooth surfaces
Authors: Wang Jiawei , Tang Bowen , Yang Hewei , Tan Wei 
Published: March 2023

Abstract
Inspired by the shield scale on the shark surface, a D-type bionic fin with non-smooth surface is proposed and used in tandem cylinders piezoelectric energy harvesters (PEHs) for the utilization of wind energy on the roof of buildings. The repeating unit of D-type bionic fin is semicircle, and the corresponding center angle of each repeating unit is 7.2°. PEHs consist of a piezoelectric cantilever beam and a wind-interference cylinder connected to the beam tip. The influence of the spacing ratio on the amplitude of PEHs with D-type bionic fins added under elastic interference is studied through wind tunnel tests and three installation positions are designed: only installed upstream, only installed downstream, and not installed upstream and downstream (bare). It is found that the maximum amplitude response law of the upstream piezoelectric energy harvester (UPEH) is not affected by the D-type bionic fins, and the D-type bionic fins can make the downstream piezoelectric energy harvester (DPEH) realize the change of the maximum amplitude from small spacing ratio to large spacing ratio. In addition, the influence of the installation position of D-type bionic fins on the output voltage of upstream and downstream PEHs is also studied. The research shows that the addition of D-type bionic fins significantly changes the vibration behavior of PEHs. D-type bionic fins can enhance the energy harvest performance by coupling "coupled vortex-induced vibration" and wake induced galloping (WIG), and increasing the surface velocity of PEHs. D-type bionic fins can also expand the bandwidth of the voltage harvested by the PEHs. The analysis of the power under the experimental wind speed shows that the installation of D-type fins in PEHs can increase the output power of the upstream and downstream PEH by 392.28% and 13% respectively compared with the bare piezoelectric energy piezoelectric energy harvester (BARE-PEH). In addition, the computational fluid dynamics is used to analyze the flow pattern, wake structure and lift coefficient of PEHs, and the reason why the installation of D-type bionic fins in the upstream has an impact on the harvest performance of upstream and downstream PEHs at 1.5 spacing ratio is explained.

Abstract
A quantum router is a device that is proposed to direct a quantum data signal in a quantum network system. Here, we demonstrate a Hamiltonian based quantum router on a four-qubit system using the IBM quantum experience platform. Transfer of information through input message qubit to the desired output qubit in a router is performed by following certain conditions. Using quantum state tomography, we show that message from the input qubit gets transferred to a particular output qubit with 0.99 fidelity. Our study also presents the time evolution of the system Hamiltonian for a four-qubit quantum router. Finally, with a three output qubit router example, we illustrate the scalability of the quantum router system using the Hamiltonian required.

Published: March 2023

Abstract
Background
Nutrition is an important issue to ensure growth and development. Nutritional knowledge is one of the factors affecting the eating habits and maintaining the healthy life. However, nutritional knowledge and life practices of medical students in Hengyang have not been studied.
Methods
A self-reported questionnaire was administered to 550 students, ranging in age from 18–23 years. Medical students from the University of South China (270 men and 280 women) participated in this research. SPSS 20.0 was used to analyze the experimental data, one way analysis of variance (ANOVA) was used for the comparison between groups, and p < 0.01 was considered statistically significant. Frequency distributions and Chi-square analyses were conducted, and a p value less than 0.01 was considered statistically significant.
Results
Our results showed that 71.45% of students had a normal BMI and 2.18% of students were underweight, with an increased prevalence of overweight and obesity. Even though students understand the importance of taking nutritional balanced food, whereas only a small number of students take it into consideration when they are selecting food.

Abstract

Background: The impact of vitamin D status on the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) has recently been the focus of interest with a lot of controversy. In this study we aimed to evaluate the impact of pre-transplant vit. D level on the outcome of HSCT. We also wanted to find an explanation of the controversy in the literature.
Methods: In this study, we evaluated the impact of vitamin D level on the risk of development of graft versus host disease (GVHD) and survival after HSCT. The study included 97 patients who received allogeneic HSCT from an identical sibling. Serum vitamin D level was measured before conditioning using ELIZA.
Student t- test, Mann-Whitney U test, ANOVA F-test and Kruskal-Wallis H tests were used to determine significance of difference for quantitative data. Pearson correlation, Spearman correlation and Chi-square test were used to determine correlations and associations. Kaplan-Meier and Log rank (Mantel-Cox) tests were used for analysis of survival. P value ≤ 0.05 was considered significant.
Results: Vitamin D level showed a range of 18.24 - 84.6 with a mean of 38.14 ± 9.73 and a median of 36.26 ng/ml. Two patients had vitamin D level <20 and 17 had a level <30 ng/ml. Acute GVHD occurred in 33 (34%) and chronic GVHD in 29 (29.9%) patients. Vitamin D level had no impact on frequency or severity of GVHD; either did it impact survival. This might be attributable to the relatively normal level in the majority of our patients on account of the sunny weather of Egypt. This might also be a potential explanation for the inconsistency of the different studies with variable levels of vitamin D. Conclusions: The current study failed to demonstrate an impact of pre-transplant vitamin D level on the outcome of HSCT. This might be attributed to the low prevalence of vitamin D deficiency in our population on account of our almost always sunny weather. The marked variability in the level of vitamin D that is considered sufficient interferes with objective comparison between studies; a consensus on what is considered sufficient, insufficient, or deficient is essential.
