Authors: Agapito Juliano , Hobold Márcia de Souza
Published: August 2022

Este texto tem como propósito sistematizar a utilização dos casos de ensino como elemento teórico-metodológico nas pesquisas acerca da formação de professores no âmbito da pós-graduação stricto sensu. O estudo, de caráter exploratório e cunho documental, toma como lócus de investigação a Biblioteca Digital de Teses e Dissertações (BDTD) e o Catálogo de Teses e Dissertações da CAPES, tendo em vista que ambas as bases de dados concentram produções dos programas de pós-graduação. A primeira etapa do estudo identificou 264 teses e dissertações, que passaram por análise de títulos, resumos e palavras-chave, consolidando 36 pesquisas que foram, efetivamente, o corpus de análise da investigação. Os 36 trabalhos foram analisados na íntegra, com o propósito de realizar uma síntese integrativa abarcando os seguintes eixos de discussão: referentes teóricos; aspectos que constituem a metodologia; e, resultados das investigações. Foram identificadas publicações a partir do ano de 2001, sendo que a maior parte das pesquisas toma os casos de ensino como instrumento de investigação e formação, geralmente associado a outros instrumentos. Naquelas pesquisas em que há centralidade dos casos de ensino como objeto de estudo, explora-se seu potencial formador e a contribuição para o desenvolvimento profissional docente. Desponta, ainda, a necessidade de que as pesquisas no campo da formação de professores explorem mais os casos de ensino como elemento formador, uma vez que estes se configuram como possibilidades de promover efetiva reflexão sobre a ação do professor.

Authors: Farias Isabel Maria Sabino de , Mussi Amali de Angelis
Published: August 2022

Este escrito apresenta-se como um ensaio teórico sobre casos de ensino na área da Educação, precisamente, sobre a sua adoção na formação de professores. Tem como objetivo dialogar criticamente com estudos e pesquisas acerca das potencialidades formativas e investigativas de casos de ensino. Propõe-se, para tanto, discutir o conceito de casos de ensino, as várias terminologias presentes na abordagem do assunto, sua emergência como instrumento de pesquisa e de formação, os fundamentos teóricos e práticos em torno de sua elaboração, bem como o seu potencial para a compreensão do desenvolvimento docente numa perspectiva crítica reflexiva, especialmente no que concerne ao seu pensamento, suas crenças e teorias pessoais, a construção dos conhecimentos profissionais e ao raciocínio pedagógico por ele utilizado. Por meio da análise teórica acerca da temática, destaca que casos de ensino podem contribuir significativamente para a produção de conhecimentos para a área educacional, e, consequentemente, para a introdução de dispositivos de formação e pesquisa que valorizem a mobilização de conhecimentos profissionais e saberes docentes; o protagonismo e a socialização profissional; um processo singular de escuta sensível do que ocorre por dentro da profissão, o que concorre para a atualidade da temática e sua relevância no contexto atual de formação docente, seja inicial ou continuada. Espera-se, portanto, contribuir para aprofundar e disseminar o debate sobre casos de ensino como instrumento na formação de professores e na produção de conhecimento no campo.
Profit Education for Black American Students
Authors: Cruz Luciano
Published: August 2022

This study examined the insertion of black American students, especially those of low socioeconomic status, in for-profit schools. The study used two theoretical categories, credentialism and cultural capital, in order to analyze the factors that influence the enrollment of students in the for-profit sector of higher education. The sample consisted of 20 students from 10 educational institutions in southern California, USA. Four main themes were captured: convenience, lack of cultural capital, credentialism and student satisfaction with the institution. The results of this study showed that most of these students were dissatisfied with their experiences in for-profit schools. Among the reasons for dissatisfaction were issues related to the lack of effective training to enable students to enter the job market, lack of confidence in the practice of their profession, the high cost of tuition that leads to large debts after graduation and feelings of loss of time and money. The study's recommendations include: (a) the need to enable students to have more knowledge about for-profit schools and different educational paths; and (b) the need for insertion and inspection of the state in schools for profit, in order to offer excellence in teaching.

Authors: Sena Lílian de Sousa , Silva Lima Márcia Raika e , Serra Ilka Márcia Ribeiro de Souza
Published: August 2022

A proposta da presente pesquisa pretende discutir as estratégias inclusivas adotadas por intérpretes de alunos surdos, em um estudo de caso realizado na cidade de Timon, no Estado do Maranhão, para compreender e direcionar o fazer pedagógico, sob a perspectiva da inclusão.O trabalho contextualiza-se durante o ensino remoto emergencial, no ano letivo de 2020, que vem alterando os processos interativos entre alunos e professores, impactando nas ações de inclusão e de aprendizagem. A pesquisa é de caráter qualitativo e o procedimento metodológico utilizado foi a entrevista compreensiva e focalizada, realizada com professores e intérpretes para coleta de dados, análises e interpretações a fim de investigar o seguinte problema: como se deu a inclusão de alunos surdos no contexto da pandemia? O arcabouço teórico que orienta este trabalho centra-se nos escritos de Vygotsky (1991) sobre o interacionismo social e aquisição da linguagem, além de Mantoan (2017), que apresenta estudos sobre inclusão; Quadros (2003; 2005) que trata sobre inclusão de surdos e Freire (1987) que propõe o protagonismo estudantil. Os resultados nos mostram que as atividades escolares, mediadas pela tecnologia, revelam o quão distantes estamos de nos tornarmos uma sociedade que pauta a Educação inclusiva e que tornar-se um professor inclusivo requer formação e mudança atitudinal.
Forecasting of daily dam occupancy rates using LSTM networks
Authors: Ayyildiz Ertugrul , Erdoğan Melike
Published: August 2022

Due to unconscious consumption of natural water resources and climate change, a water crisis is expected in the upcoming years. At this point, it is necessary to know the water levels in the dams and develop strategies for water-saving applications in the coming periods. This study aimed to propose the artificial neural network models for forecasting the water in the dams that provide usable water for the future. For this reason, long short-term memory (LSTM) networks that are a type of recurrent neural networks are employed to make future forecasts. The daily dam occupancy rate data between 2005 and 2021 for İstanbul is used to train the LSTM network. Then, the developed models are used to forecast over the next 30 days. The data are used in ARIMA to model the daily dam occupancy time series, for a fair comparison. The forecast values gained by the proposed LSTM network are compared with the traditional methods using RMSE and MAPE for all the forecast horizons. The results show that the LSTM-based forecast model always has a better accuracy rate than the ARIMA.

Los efectos del IDH sobre las emisiones de CO2 en América Latina y el Caribe
Authors: Villegas Pocaterra Esmeralda , Molero Oliva Leobaldo Enrique , Rodríguez López Virginia Elizabeth , Andino Chancay Tanya Shyrna
Published: August 2022

El propósito de esta investigación es estimar el efecto del índice de desarrollo humano (IDH) sobre las emisiones de dióxido de carbono per cápita con datos de 19 países de América Latina y el Caribe que cubren el período 1990-2019 con frecuencia anual. En cuanto al nivel de desarrollo humano, se evaluaron los índices de las dimensiones ingresos, salud y educación. Se utilizó una regresión cuantílica para estimar el efecto del regresor IDH sobre los diferentes cuantiles de la distribución de las emisiones per cápita. De acuerdo con los resultados, el efecto es mayor en los deciles superiores de la distribución de las emisiones, por lo que, de no adoptarse políticas específicas en la dimensión ambiental, la consecución de mayores niveles de desarrollo humano, indicado por un IDH más alto, tendría consecuencias perniciosas sobre las emisiones, haciendo que el desarrollo no esté acompañado de sostenibilidad ambiental.

La composición física, química y biológica de los sedimentos se ha usado ampliamente como indicador de calidad ambiental de los ecosistemas acuáticos, no obstante, la aplicación de directrices de calidad permite estimar de manera práctica los riesgos ecológicos asociados a la presencia de elementos potencialmente tóxicos (EPT) como metales, metaloides y otros. En este trabajo se evaluó el riesgo ecológico por Pb, Cd, Cr, Zn y Cu en sedimentos costeros del Lago de Maracaibo (Venezuela), mediante un enfoque multidirectrices (índices de enriquecimiento elemental y evaluación de riesgo ecológico potencial). Para ello, se recolectaron 33 muestras de sedimentos superficiales en 11 estaciones de muestreo de la zona costera del lago, para determinar los niveles totales de los EPT mediante espectrometría de absorción atómica con horno de grafito, previa digestión ácida en reactores de alta presión. Las concentraciones medias fueron de 3.811 ± 3.161, 0.032 ± 0.090, 8.574 ± 6.429, 26.480 ± 3.762 y 2.644 ± 1.792 mg/kg de masa seca para Pb, Cd, Cr, Zn y Cu, respectivamente. Los valores de los índices aplicados señalaron riesgos ecológicos de moderados a considerables por la presencia de Cd en algunas localidades, no obstante, las directrices de calidad de sedimento destacaron que la probabilidad de ocurrencia es muy baja o despreciable (9 %), considerándose un ambiente propicio para la vida acuática. Los EPT con mayor potencial de riesgo ecológico fueron Cd y Zn, mientras que el Cu exhibió las menores posibilidades de efectos adversos. Es necesario evaluar el riesgo ecológico potencial asociado a EPT en sedimentos internos de la bahía, el estrecho y de la zona central del lago.

Studies suggest that elevated postnatal blood lead levels (BLLs) are negatively associated with child growth. This study aimed to investigate associations of childhood BLLs at age one-year and growth outcomes at age six-years (n=661) in a cohort of children in Allada, Benin. The growth outcomes studied are weight-for-age Z-score (WAZ), height-for-age Z-score (HAZ) and BMI-for-age Z-score (BMIZ), head circumference (HC), underweight, stunting, and wasting. Multivariable regression models examined associations between blood lead levels, growth outcomes with adjustment for potential confounders. The geometric mean BLLs was 59.3 μg/L and 82% of children had BLLs >35 μg/L at one year. After adjusting for confounding factors, no association was found between BLLs quartiles and HAZ, WAZ, BMIZ, and height and weight growth velocities. However, boys in the highest quartile had 1.02 cm lower HC (95% CI: [-1.81, -0. 24]) as compared to those in the lowest quartile with a dose-response trend across quartiles (Ptrend =0.02). Furthermore, an increased risk of being stunted was observed in children in the highest quartile of exposure compared to the first (OR: 2.43; 95% CI: [1.11 – 5.33]) with a dose-response trend (Ptrend =0.03). Blood lead was found to be associated with an increased risk of childhood stunting and lower head circumference in a resource-limited setting.
The Approximate Analytical Solution for the Top-Of-Atmosphere Spectral Reflectance of Atmosphere – Underlying Snow System Over Antarctica
Authors: Kokhanovsky Alexander
Published: August 2022

The optical signals detected on multiple satellite platforms over snow surfaces are determined by the optical properties of snow surface and atmosphere. The solution of both direct and inverse problems of an atmosphere – underlying snow system requires simple relationships between top-of-atmosphere (TOA) reflectance R and microphysical/optical characteristics of both snow and atmosphere. The task of this paper is to present a simple analytical relationship between the value of R as detected on a satellite with atmosphere/snow properties. Such a relationship can be established using a numerical solution of integro - differential radiative transfer equation (RTE) (Liou, 2022). However, this path is quite complicated and time consuming. The analytical solutions of RTE are needed for the solution of various applied atmospheric and snow optics problems (Cachorro et al., 2022; Mei et al., 2020, 2022; Kokhanovsky, 2021). This is the main driver of this work. To simplify the problem under study we consider the case of Antarctica, where both snow and atmosphere are almost free of pollutants. This work is focused on the simulation of the moderate spectral resolution TOA measurements (1nm or so) and the spectral range 400-1000nm.

The high costs of cancer treatment and lack of investment in health care are significant obstacles to public health on the African continent. The objective of this study was to estimate the financial cost of treating children suffering from cancer in Africa. We conducted a systematic review and meta-analysis of expert opinions between March 2000 and March 2020. The key search terms included ‘cost’, ‘cancer’ and ‘child’; we selected articles that specifically addressed the financial costs of childhood cancer in African countries. Of the 103 articles found, 18 met the inclusion criteria. Cancer care was a heavy financial burden in most of the countries studied, although costs varied from country to country; the average expenditure on healthcare was US$1017.39 ± US$319.1 per year. In countries without a health insurance system, the highest proportion of cancer care costs, 46.6%, was indirect, whereas in countries with a cancer financing system, the direct cost of treatment was low, 53.4%. The cost of treating childhood cancer is high in Africa in relation to the standard of living of individuals residing in this region.

Computing the Total $H$-irregularity Strength of Edge Comb Product of Graphs
Authors: Wahyujati Mohamad Fahruli , Susanti Yeni
Published: August 2022

A simple undirected graph $\Gamma=(V_\Gamma,E_\Gamma)$ admits an $H$-covering if every edge in $E_\Gamma$ belongs to at least one subgraph of $\Gamma$ that isomorphic to a graph $H$. For any graph $\Gamma$ admitting $H$-covering, a total Labelling $\beta: V_\Gamma \cup E_\Gamma \longrightarrow \{1,2,\dots,p\}$ is called an $H$-irregular total $p$-labelling of $\Gamma$ if every two different subgraphs $H_1$ and $H_2$ of $\Gamma$ isomorphic to $H$ have distinct weights where the weight $w_\beta(K)$ of subgraph $K$ of $\Gamma$ is defined as $w_f(K):=\displaystyle \sum_{v\in V_K} f(v) + \sum_{e\in E_K} f(e)$. The smallest number $p$ for which a graph $\Gamma$ admits an $H$-irregular total $p$-labelling is called the total $H$-irregularity strength of $\Gamma$ and is denoted by $ths(\Gamma)$. In this paper, we determine the total $H$-irregularity strength of edge comb product of two graphs.
Modelling Recent and Future Climate Scenarios Impact on Malaria Transmission in Senegal using bias-corrected CMIP6
Authors: Diouf Ibrahima , Ndione Jacques-André , Gaye Amadou Thierno
Published: August 2022

Malaria is a constant reminder of the climate change impacts on health. Many studies have investigated the influence of climatic parameters on the of malaria transmission. Climate conditions can modulate malaria transmission through increased temperature, which reduces the duration of the parasite's reproductive cycle inside the mosquito. The intensity and frequency of the rainfall modulate the development of the mosquito population. In this study, the Liverpool Malaria Model (LMM) is used to simulate the spatio-temporal variation of the malaria incidence in Senegal. The simulations are based on the WATCH Forcing Data applied to ERA-Interim data (WFDEI) used as a point of reference, and biased-corrected CMIP6 models, separating historical and projections for 3 Shared Socio-economic Pathways scenarios (SSP126, SSP245 and SSP585). Our results highlight a strong increase in temperatures, especially towards eastern Senegal under the SSP245 but mainly the SSP585 scenarios. The ability of the LMM model to simulate the seasonality of malaria incidence is assessed. The model reveals a period of high malaria transmission between September and November with a maximum reached in October. Results indicate a decrease in malaria incidence in certain regions of the country for the far future and for the extreme scenario. This study is importance for the planning, prioritization, and implementation of control activities in Senegal.

Published: August 2022

Vacation is an integral part of the modern life for many people, while there is a fundamental assumption that a short-term vacation agrees with your health, and therefore a factor for improving quality of life. The purpose of the study was to analyze the main indicators of physical development and cardiovascular system in young people of the North who leave and do not leave the region for a summer vacation. Material and methods: the author has conducted a survey of 126 young residents of the Magadan region aged 16-18 (the average age 17.2±0.8 years), who were divided into the following two groups: young people traveling outside the Magadan region for a summer vacation on an annual basis or once in two years and young people who have not left the region for vacation for more than 3 years (on average 7±1.2 years)). The main indicators of physical development and cardiovascular system were determined in the survey participants. Results: The survey shows that 37% of young people travel outside the Magadan region for vacation on an annual basis, 40% leave the region every two years and 30% have not left the region for more than 3 years, while 3% of the surveyed sample have never left the Magadan region. According to the data obtained, in the group of people who do not leave the region for vacation, imbalances in the cardiovascular system have been registered, manifested by a significant increase in systolic blood pressure against the background of increased processes of mechanical activity of the heart, manifested in the increased myocardial oxygen demand and gas exchange in general. Conclusion: The study results expand knowledge about positive contribution of summer vacation to the health and well-being of the younger generation of the Northern region. It should be particularly noted that the beneficial effect of leaving the Magadan region for a summer vacation can be objectively measured by indicators of the cardiovascular system. The data obtained fully provide basis for further research in the field of organizing summer vacation as a public health resource.

Aging is one of the major global demographic trends, including in the Russian Federation. In this regard, health officials pay a special attention to the resource and regulatory support for care delivery to people older than working age, taking into account the changed conditions and capabilities of medical organizations. The purpose of the study was to assess normative documents and main indicators characterizing the number and performance of geriatricians providing medical care to the elderly and senile people. Material and methods: retrospective analysis of data from federal statistical observation forms No. 30 for the period from 2015 to 2020, data on the population aged 60 years and older, Rosstat data, orders of the Ministry of Health of the Russian Federation No. 38 and No. 297. Content analysis of regulatory documents, statistical (calculation of extensive and intensive indicators), descriptive statistics using MS Office Excel 2016, Statistica 6.1. The study results showed that, despite a gradual increase in the number of geriatricians and relevant visits by patients of this category, the full-time position staffing remains low, affecting a growth in the part-time coefficient, suggesting a need for training geriatricians. For example, the number of geriatricians in Russia as a whole in 2020 equaled to 0.09 per 10,000 population older than working age. The ongoing decline in medical position staffing against a background of a positive growth rate in the number of medical specialists is probably due to the gap between the increasing number of full-time positions and the staffing rate by individuals. Conclusion: the study results have identified the need for developing time standards that correspond to the modern conditions of primary care delivery by geriatricians, as well as establishing workload standards and the actual number of doctors in this specialty to ensure high-quality care delivery to the elderly.

Significance. One of the strategic priorities of the Russian domestic policy is to increase life expectancy to 78 and 80 years in 2024 and 2030, respectively. High mortality from curable diseases that contributes to the decrease in life expectancy in the Krasnoyarsk Territory can be associated with low access to timely medical care. The current policy in the economic and social spheres should contribute to reducing mortality from curable diseases, which ultimately should result in the increased life expectancy. The purpose of the study is to analyze dynamics in contribution of mortality from curable diseases to the decrease in life expectancy in the Krasnoyarsk Territory to evaluate the current situation and identify prospects for increasing life expectancy. Material and methods. Contribution to the decrease in life expectancy was calculated according to the method of assessing eliminated reserves. To assess dynamics in the analyzed indicators, the total and average annual growth and loss rates, expressed as a percentage, were calculated. Results. The study has assessed contribution of mortality from curable diseases to the decrease in life expectancy calculated during the study. The assessed contribution makes it possible to evaluate possible reserves of the Krasnoyarsk Territory healthcare system cat can be mobilized using modern and effective medical interventions, including secondary prevention and treatment, to decrease mortality in the light of the target values of life expectancy established at the federal level. A special focus in the Krasnoyarsk Territory should be placed on mortality from diseases of the circulatory system, neoplasms and diseases of the digestive system associated with curable causes. Conclusion. Improving quality of treatment and secondary prevention of such curable diseases will make it possible to improve life quality and decrease premature deaths resulting in the increased life expectancy in the Krasnoyarsk Territory.

Effects of intrinsic properties, particle size, bulk density and specific gravity on thermal properties of coal dusts
Authors: Sahu Aashish , Mishra Devi Prasad
Published: August 2022

Thermal properties of pulverized coal govern the heat transfer and greatly influence the coal dust explosion and spontaneous combustion processes. This study measures the thermal properties of five coal samples at six distinct particle sizes using an advanced Thermal Property Analyzer. The thermo-physical properties of coal dust positively correlated with particle size. Thermal conductivity, diffusivity and specific heat capacity increased with increase in the ash percentage, bulk density, and specific gravity of coal dust, whereas they negatively correlated with fixed carbon and volatiles content of coal. Empirical relations between the thermo-physical properties were developed. The thermal conductivity, diffusivity, and specific heat capacity of coal dusts varied in the ranges of 0.091–0.147 W/mK, 0.125–0.164 mm²/s, and 0.715–0.945 MJ/m³K, respectively. With increase in particle size from < 38 to 500–1000 µm, thermal conductivity, thermal diffusivity and specific heat capacity increased in the range of 25.60-32.89%, 9.76–22.11%, and 9.57–20.80%, respectively for different coal samples.

Invasion risks may be influenced either negatively or positively by climate change, depending on the species. These can be predicted with species distribution models, but projections can be strongly affected by input environmental data (climate data source, Global Circulation Models and Shared Socio-economic Pathways SSP). We modelled the distribution of Phelsuma grandis and P. laticauda , two Malagasy reptiles that are spreading globally. We accounted for drivers of spread and establishment using socio-economic factors (e.g., distance from ports) and two climate data sources, i.e., Climatologies at High Resolution for the Earth’s and Land Surface Areas (CHELSA) and Worldclim. We further quantified the degree of agreement in invasion risk models that utilised CHELSA and Worldclim data for current and future conditions. Most areas identified as highly exposed to invasion risks were consistently identified (e.g. in Caribbean and Pacific Islands). However, projected risks differed locally. We also found notable differences in quantitative invasion risk (3% difference in suitability scores for P. laticauda and up to 14% for P. grandis ) under current conditions. Despite both species native distributions overlap substantially, climate change will drive opposite responses on invasion risks by 2070 (decrease for P. grandis, increase for P. laticauda ). Overall, projections of future invasion risks were the most affected by climate data source, followed by SSP. Our results highlight that assessments of current and future invasion risks are sensitive to the climate data source, especially in Islands. We stress the need to account for multiple climatologies when assessing invasion risks.

Bacillus velezensis is a new species of Bacillus sp recently discovered. It is considered a new plant growth promoting rhizobacteria because of its ability to inhibit a variety of pathogens and promote plant growth. In this study, we isolated a novel Bacillus velezensis strain ES2-4 in orchard soil. Based on comparative analysis, including average nucleotide polymorphism (ANI), digital DNA-DNA hybridization (dDDH), and phylogenetic analysis, ES2-4 was designated as Bacillus velezensis. Genomic analysis revealed that Bacillus velezensis contains a series of genes closely related to promoting plant growth directly and indirectly. Genomic secondary metabolite analyses indicated there are 9 identified gene clusters involved in the biosynthesis of various secondary metabolites (Surfactin, Iturin, Fengycin, Bacillibactin, Bacilysin, Macrolactin, Bacillaene, Difficidin, Amylocyclicin), and five clusters encoding polyketides, lanthipeptide, terpenes, but the specific substances are unclear. In addition, Bacillus velezensis ES2-4 showed good antagonistic activity against various plant pathogens, especially Rhizoctonia solani. These findings suggest that Bacillus velezensis ES2-4 could be used as a PGPR strain to develop new biofertilizers and biocontrol agents.
Characteristics of food insecurity prevalence in North Philadelphia Federally Qualified Health Center target populations, a cross-sectional study
Authors: Inguito Kai , Joa Brandon , Gardner James , Fung Eric N. , Layer Laura , Fritz Karen
Published: August 2022

Background
The prevalence of food insecurity declined in the United States but paradoxically increased in the large metropolitan area of Philadelphia in the past decade, and compared to the general U.S. population, a greater percentage of households in Philadelphia are affected by food insecurity and dependent on programs such as SNAP. The objective of this study was to determine food insecurity prevalence and demographics of the populations near Philadelphia Federally Qualified Health Center (FQHC) clinics. In line with risk factors on the national level, we hypothesized that food insecure people in a low-income area of Philadelphia would be more likely to be older, female, Hispanic, and overweight or obese.
Methods
This cross-sectional study took place in North Philadelphia, a populous section of Philadelphia with a high concentration of poverty and many zip codes reporting 30–45% or more of the population below the federal poverty line. Students and clinicians affiliated with a local FQHC conducted surveys on residents (n = 379) within 1-mile radiuses of three FQHC sites using the validated food security tool, the Hunger Vital Sign™. Survey data were collected through door-to-door visits in the summer of 2019. We used multivariate logistic regression models to predict food insecurity with independent variables including age, sex, language preference, and BMI category.
Results
The percentage of food insecurity in the area surveyed was much higher (36.9%) than previously reported in both Philadelphia and nationwide. Contrary to our hypothesis, food insecure individuals were younger on average and more likely to be English-speaking; these individuals had statistically significant lower mean BMI and lower odds of being overweight or obese vs. normal weight, with no significant difference by sex.
Conclusion
These North Philadelphia areas had a high prevalence of food insecurity associated with normal and low BMI and demographics of younger, English-speaking individuals. Some of these findings may be related to local confounding factors such as employment or substance abuse status, demonstrating a need for public health and organizations to work together for more locally targeted research and interventions on food insecurity in impoverished urban settings.

IntroductionDue to the accelerated pace and quantum of scientific publication during the COVID-19 pandemic, a large number of articles on COVID-19 have been retracted. Pre-prints though not peer-reviewed offer the advantage of rapid dissemination of new findings. In this study, we aim to systematically compare the article characteristics, time to retraction, social media attention, citations, and reasons for retraction between retracted pre-print and peer-reviewed articles on COVID-19. MethodsWe utilized the Retraction Watch database to identify retracted articles on COVID-19 published from 1st January 2020 to 10th March 2022. The articles were reviewed and metadata such as article characteristics (type, category), time to retraction, reasons for retraction, and Altmetric Attention Score (AAS) and citation count were collected. ResultsWe identified 40 retracted pre-prints and 143 retracted peer-reviewed articles. The median (IQR) retraction time for pre-print and peer-reviewed articles was 29 (10-81.5) days and 139 (63-202) days (p = 0.0001). Pre-prints and peer-reviewed article had median (IQR) AAS of 26.5 (4-1155) and 8 (1-38.5), respectively (p = 0.0082). The median (IQR) citation count for pre-prints and peer-reviewed articles was 3 (0-14) and 3 (0-17), respectively (p = 0.5633). The AAS and citation counts were correlated for both pre-prints (r = 0.5200, p = 0.0006) and peer-reviewed articles(r = 0.5909, p = 0.0001). The commonest reason for retraction for pre-prints and peer-reviewed articles concerns about data and results.ConclusionThe increased adoption of pre-prints results in faster identification of erroneous articles compared to the traditional peer-review process.

This study sets out to explore the nexus between energy consumption, economic growth, and quality of the environment within the separate contexts of BRICS and the Next 11 Countries. The empirical analysis is carried out using the Feasible Generalized Least Squares (FGLS) modeling approach, which considers cross-sectional dependency analysis, cross-sectional heterogeneity, and cointegration analysis. The empirical results show that BRICS countries support the EKC hypothesis, but the Next-11 countries have a U-shaped path between economic growth and environmental degradation, which is contrary to the conventional EKC hypothesis. Moreover, the nexus between economic growth share in the quality of the environment and energy consumption is also seen to exhibit nonlinearity. Besides, unidirectional causations are confirmed between CO2 emissions and energy consumption for BRICS countries. However, a unidirectional causal linkage moves from CO2 emissions to energy consumption for the Next 11 countries. Thus, these findings have profoundly important policy consequences for the achievement of the BRICS and the Next 11 countries' energy stability and environmental protection, mainly by reducing the higher energy usage of these countries.JEL Classification: C51, F64, O13, O44, P18

There has been a renewed interest for larviciding during the recent decade. Although biological larvicides are considered not to be harmful to non-target organisms, there is still not sufficient data on the effect of new long lasting larvicide formulations such as VectoMax G combiningBacillus thuringiensis israelensisandB. sphaericuson the environment especially on non-target organisms. The present study aimed to assess the possible influence of VectoMax G on the diversity and abundance of the aquatic fauna cohabiting with mosquito larvae in breeding habitats during a larviciding trial in the city of Yaoundé. Twelve districts of the city of Yaoundé divided into 6 intervention and 6 control sites were chosen for the study. In each district 4 semi-permanent or permanent aquatic habitats were followed. VectoMax G application was done once every two weeks during 6 months and aquatic organisms were collected 48h after each treatment. All collected organisms were brought to the laboratory for identification. Physico-chemical parameters were recorded as well. A high diversity of the zooplankton was recorded in the intervention areas with 28 species collected against 14 species in the control areas. Cladocerans were the most represented group in both sites while Oestracods were found only in control sites. A total of 19 macro-invertebrates species were recorded in the control areas vs 16 species in the intervention areas. Gasteropods were the most represented groups of macro-invertebrates. Vertebrates such as larvivorous fishes and amphibians larvae were also found in approximately similar densities in both sites. The study indicated no significant influence of larviciding with VectoMax G on the diversity and abundance of the non-target aquatic fauna in the city of Yaoundé.
