Corpo e escola: o que o brincar nas filas [re]vela
Authors: Spolaor Gabriel Da Costa , Prodócimo Elaine
Published: June 2020

Neste trabalho tivemos como objetivo investigar o brincar nas filas de uma Escola de Tempo Integral da prefeitura Municipal de Campinas. Para tanto, realizamos uma pesquisa de cunho qualitativo interpretativo, observando uma turma de 1º ano do ciclo I do Ensino Fundamental, durante um semestre. Utilizamos diário de campo e escrevemos narrativas sobre as observações no processo de produção dos dados. Chamamos atenção principalmente para as estratégias de controle dos corpos e expressões utilizadas pelas professoras, assim como, para o brincar transgressor e resistente, que rompia com a continuidade na dinâmica da cultura escolar, subvertendo ou pelo menos revelando que outra escola seria possível de existir, com outras normas, outras configurações, outras regras, outros sentidos e significações.
Os saberes corporais na Educação Física escolar: reflexões acerca dos processos avaliativos
Authors: Brasil Isabella Blanche Gonçalves , Ferreira Lílian Aparecida
Published: June 2020

Na Educação Física escolar a avaliação dos saberes corporais vem se mostrando como um campo ainda pouco explorado pelo debate acadêmico. Neste sentido, o objetivo desta pesquisa foi analisar um processo avaliativo, envolvendo a utilização de fichas nas aulas de Educação Física no ensino médio, dos saberes corporais dos estudantes acerca do handebol. Pautada pela pesquisa-ação, a investigação foi desenvolvida ao longo de seis meses com uma turma de 30 estudantes do ensino médio. As coletas foram realizadas por meio de diário de aula (produzido pela professora) e questionários aplicados aos estudantes. A utilização das fichas avaliativas possibilitou a captação expressiva de elementos correspondentes aos aspectos técnicos, táticos, volitivos e físicos do jogo de handebol, individual e coletivamente. A  avaliação entre pares permitiu a partilha de saberes e trouxe aos estudantes a oportunidade de ‘olhar’ o jogo atentamente e aprender com isso. Esta dinâmica também contribuiu para o entendimento e a sensibilização da/com a história de vida do outro em relação às experiências esportivas, promovendo maior respeito entre os discentes.  Os resultados dos recursos utilizados para avaliar os saberes corporais dos estudantes nas aulas de Educação Física expressam a necessidade de uma reorientação das práticas pedagógicas, o que envolve, dentre outros aspectos, um conhecimento sobre as estruturas, dinâmicas e interações características de cada prática corporal

Published: June 2020

Propomos com este escrito apresentar a evolução histórica da estrutura do esporte em Moçambique. Para tanto, foram selecionados três professores e quatro dirigentes que viveram a história e a evolução da área da Educação Física (EF) e esporte no país. Utilizamos documentos históricos e entrevista semiestruturada com os participantes. A análise de conteúdo foi utilizada para análise e interpretação dos materiais encontrados e das entrevistas. O contexto sociocultural da EF e esporte em Moçambique foram marcados por dois períodos históricos: a era colonial (1927-1974), na qual se estabeleceram as bases para a estruturação da EF vigente em Moçambique e a era pós-independência (1975-2016), caracterizada pela regulamentação, criação de políticas e formação de profissionais de EF e esporte visando a dinamização da área. Nesse processo, apesar das condições sociais e econômicas precárias vivenciadas no período colonial e pós-independência, o governo moçambicano desempenhou um papel mediador que contribuiu para o desenvolvimento da área.

St. Lucia, a tourism-dependent economy in the Caribbean, has been hit hard by
the COVID-19 pandemic. Tourism exports, which in a typical year would account for nearly
90 percent of the country’s foreign exchange earnings, have come to an abrupt halt with
widespread cancellations spreading out into the foreseeable future. The economy is now
projected to contract by 8.5 percent in 2020. More severe local outbreaks of COVID-19
could cause additional widespread and prolonged disruptions to economic activity.
Republic of Belarus

Published: June 2020

The National Bank of the Republic of Belarus (NBRB) is reforming its monetary policy framework in line with recommendations of past IMF TA missions and its Road Map for Transitioning to Inflation Targeting with the aim of eventually adopting inflation targeting (IT). Transitioning to IT would require, among other measures and reforms, strengthening the monetary policy forecasting and analysis system (FPAS) and better integrating the core quarterly projection model (QPM) into the decision-making process. This TA mission was the fifth from series of quarterly IMF TA missions focused on the FPAS capacity building. It was mainly aimed to simulate initial conditions and compile a QPM-based forecast scenario as a part of a practical forecasting round at the NBRB in March. Moreover, the mission worked with the modeling team to deepen its understanding of the QPM’s role in policy decision making and in internal communication.

Published: June 2020

The COVID-19 shock hit Jamaica only a few months after the successful completion
of its precautionary Stand-By Arrangement with the Fund, which was underpinned by strong
ownership and civil society oversight. Jamaica’s established track record of economic reforms
has created buffers that are invaluable today in responding to the COVID-19 crisis. However,
the domestic impact of the outbreak, increasing fiscal needs, falling remittances, and a sudden
stop in tourism receipts are generating a sizable balance-of-payments need. The authorities
are, therefore, requesting emergency financial support under the Rapid Financing Instrument
(RFI) of 100 percent of quota (SDR 382.9 million or about US$520 million).

The COVID-19 pandemic is having a severe impact on Malawi’s economy.
Spillovers from the global slowdown, border closures, and economic disruption in
neighboring countries have reduced exports, raised trade transit costs, and weighed on
remittances, tourism, and foreign direct investment; and a country-wide lockdown—to
curb growing cases and deaths from COVID-19—has slowed domestic activity. Malawi’s
public health system is poorly equipped to manage this major public health emergency.
Database for the kinetics of the gas-phase atmospheric reactions of organic compounds
Authors: McGillen Max R. , Carter William P. L. , Mellouki Abdelwahid , Orlando John J. , Picquet-Varrault Bénédicte , Wallington Timothy J.
Published: June 2020

Abstract. We present a digital, freely available, searchable, and
evaluated compilation of rate coefficients for the gas-phase reactions of
organic compounds with OH, Cl, and NO3 radicals and with O3.
Although other compilations of many of these data exist, many are
out of date, most have limited scope, and all are difficult to search and to
load completely into a digitized form. This compilation uses results of
previous reviews, though many recommendations are updated to incorporate new
or omitted data or address errors, and includes recommendations on many
reactions that have not been reviewed previously. The database, which
incorporates over 50 years of measurements, consists of a total of 2765
recommended bimolecular rate coefficients for the reactions of 1357 organic
substances with OH, 709 with Cl, 310 with O3, and 389 with NO3,
and is much larger than previous compilations. Many compound types are
present in this database, including naturally occurring chemicals formed in
or emitted to the atmosphere and anthropogenic compounds such as halocarbons
and their degradation products. Recommendations are made for rate
coefficients at 298 K and, where possible, the temperature dependences over
the entire range of the available data. The primary motivation behind this
project has been to provide a large and thoroughly evaluated training
dataset for the development of structure–activity relationships (SARs),
whose reliability depends fundamentally upon the availability of
high-quality experimental data. However, there are other potential
applications of this work, such as research related to atmospheric lifetimes
and fates of organic compounds, or modelling gas-phase reactions of organics
in various environments. This database is freely accessible at

The Berkeley Earth Land/Ocean Temperature Record
Authors: Rohde Robert A. , Hausfather Zeke
Published: June 2020

Abstract. A global land/ocean temperature record has been created by combining the Berkeley Earth monthly land temperature field with spatially-kriged version of the HadSST3 dataset. This combined product spans the period from 1850 to present and covers the majority of the Earth's surface: approximately 57 % in 1850, 75 % in 1880, 95 % in 1960, and 99.9 % by 2015. It includes average temperatures in 1° × 1° lat/lon grid cells for each month when available. It agrees quite well with records from Hadley's HadCRUT4, NASA's GISTEMP, NOAA's GlobalTemp, and Cowtan and Way, but provides a more spatially complete and homogeneous temperature field. Two versions of the record are provided treating areas with sea ice cover as either air temperature over sea ice or sea surface temperature under sea ice. The choice of how to assess the temperature of areas with sea ice coverage has a notable impact on global anomalies over past decades due to rapid warming of air temperatures in the Arctic. Accounting for rapid warming of Arctic air suggests ~ 0.1 °C additional global-average temperature rise since the 19th century than temperature series that do not capture the changes in the Arctic. Updated versions of this dataset will be presented each month at the Berkeley Earth website (http://berkeleyearth.org/data/), and a convenience copy of the version discussed in this paper has been archived and is freely available at https://doi.org/10.5281/zenodo.3634713 (Rohde & Hausfather, 2020).
Parameterization of river incision models requires accounting for environmental heterogeneity: insights from the tropical Andes
Authors: Campforts Benjamin , Vanacker Veerle , Herman Frédéric , Vanmaercke Matthias , Schwanghart Wolfgang , Tenorio Gustavo E. , Willems Patrick , Govers Gerard
Published: June 2020

Abstract. Landscape evolution models can be used to assess the impact of
rainfall variability on bedrock river incision over millennial timescales.
However, isolating the role of rainfall variability remains difficult in
natural environments, in part because environmental controls on river
incision such as lithological heterogeneity are poorly constrained. In this
study, we explore spatial differences in the rate of bedrock river incision
in the Ecuadorian Andes using three different stream power models. A
pronounced rainfall gradient due to orographic precipitation and high
lithological heterogeneity enable us to explore the relative roles of
these controls. First, we use an area-based stream power model to scrutinize
the role of lithological heterogeneity in river incision rates. We show that
lithological heterogeneity is key to predicting the spatial patterns of incision
rates. Accounting for lithological heterogeneity reveals a nonlinear
relationship between river steepness, a proxy for river incision, and
denudation rates derived from cosmogenic radionuclide (CRNs). Second, we explore
this nonlinearity using runoff-based and stochastic-threshold stream power
models, combined with a hydrological dataset, to calculate spatial and
temporal runoff variability. Statistical modeling suggests that the
nonlinear relationship between river steepness and denudation rates can be
attributed to a spatial runoff gradient and incision thresholds. Our
findings have two main implications for the overall interpretation of
CRN-derived denudation rates and the use of river incision models: (i)
applying sophisticated stream power models to explain denudation rates at
the landscape scale is only relevant when accounting for the confounding
role of environmental factors such as lithology, and (ii) spatial patterns in
runoff due to orographic precipitation in combination with incision
thresholds explain part of the nonlinearity between river steepness and
CRN-derived denudation rates. Our methodology can be used as a framework to
study the coupling between river incision, lithological heterogeneity and
climate at regional to continental scales.
Image Processing Based Atmospheric River Tracking Method Version 1 (IPART-1)
Authors: Xu Guangzhi , Ma Xiaohui , Chang Ping , Wang Lin
Published: June 2020

Abstract. Automated detection of atmospheric rivers (ARs) has been heavily relying on magnitude thresholding on either the integrated water vapor (IWV) or integrated vapor transport (IVT). Magnitude thresholding approaches can become problematic when detecting ARs in a warming climate, because of the increasing atmospheric moisture. A new AR detection method derived from an image processing algorithm is proposed in this work. Different from conventional thresholding methods, the new algorithm applies threshold to the spatio-temporal scale of ARs to achieve the detection, thus making it magnitude independent and applicable to both IWV- and IVT-based AR detections. Compared with conventional thresholding methods, it displays lower sensitivity to parameters and a greater tolerance to a wider range of water vapor flux intensities. A new method of tracking ARs is also proposed, based on a new AR axis identification method, and a modified Hausdorff distance that gives a measure of the geographical distances of AR axes pairs.
On the shape of forward transit time distributions in low-order catchments
Authors: Heidbüchel Ingo , Yang Jie , Musolff Andreas , Troch Peter , Ferré Ty , Fleckenstein Jan H.
Published: June 2020

Abstract. Transit time distributions (TTDs) integrate information
on timing, amount, storage, mixing and flow paths of water and thus
characterize hydrologic and hydrochemical catchment response unlike any
other descriptor. Here, we simulate the shape of TTDs in an idealized
low-order catchment and investigate whether it changes systematically with
certain catchment and climate properties. To this end, we used a physically
based, spatially explicit 3-D model, injected tracer with a precipitation
event and recorded the resulting forward TTDs at the outlet of a small
(∼6000 m2) catchment for different scenarios. We found
that the TTDs can be subdivided into four parts: (1) early part – controlled
by soil hydraulic conductivity and antecedent soil moisture content, (2) middle part – a transition zone with no clear pattern or control, (3) later
part – influenced by soil hydraulic conductivity and subsequent
precipitation amount, and (4) very late tail of the breakthrough curve –
governed by bedrock hydraulic conductivity. The modeled TTD shapes can be
predicted using a dimensionless number: higher initial peaks are observed if
the inflow of water to a catchment is not equal to its capacity to discharge
water via subsurface flow paths, and lower initial peaks are connected to
increasing available storage. In most cases the modeled TTDs were humped
with nonzero initial values and varying weights of the tails. Therefore,
none of the best-fit theoretical probability functions could describe the
entire TTD shape exactly. Still, we found that generally gamma and
log-normal distributions work better for scenarios of low and high soil
hydraulic conductivity, respectively.
Study on dynamic characteristics of underwater pressure compensator considering nonlinearity
Authors: Li Songyu , Du Xinguang , Zhang Luyao , Chen Ken , Wang Shuai
Published: June 2020

Abstract. The external pressure is the biggest problem faced by
underwater hydraulic systems. The strength and sealing ability of the
structure are facing enormous challenges. For this problem, the common
solution is to use pressure compensation technology. The pressure of the
seawater is transmitted to the inside of the hydraulic system through a
pressure compensator, which equalizes the return pressure of the hydraulic
system and the seawater pressure. The structure of the compensation system,
the volume and dynamic characteristics of the compensator, and the
compensation failure caused by hydraulic oil leakage will all affect the
normal operation of the underwater equipment. Therefore, it is necessary to
study the pressure compensation system. This paper analyzes the pressure
characteristics of the rubber-bellows type compensator. The dynamic
characteristic equation of the pressure is established. Due to the strong
nonlinear nature of rubber, the finite element method is used to simulate
the deformation process of the rubber-bellows type pressure compensator. The
relationship between the volume variation and the spring displacement of the
rubber-bellows type pressure compensator is calculated by FE simulation. The
relationship is brought into the theoretical equation result to obtain the
pressure characteristics of the compensator. Through the control variable
method, the influence of damping, total mass, effective area and spring
stiffness on the internal pressure of the compensator is obtained. According
to the analysis result, the damping ratio should be appropriately increased
to reduce the overshoot of pressure fluctuations in the design. Since the
damping is difficult to control, the total mass of the end cap, the guide
post, the rubber bellows and the spring can be minimized. It also reduces
the quality of the equipment. The spring stiffness and effective area have a
significant influence on the steady-state pressure. A softer spring should
be used and the effective area should be increased as much as possible to
reduce the final steady-state pressure.
Data assimilation of sea surface temperature and salinity using basin-scale EOF reconstruction: a feasibility study in the NE Baltic Sea
Authors: Zujev Mihhail , Elken Jüri , Lagemaa Priidik
Published: June 2020

Abstract. The tested data assimilation (DA) method based on EOF (Empirical Orthogonal Functions) reconstruction of observations decreased RMSD of surface temperature (SST) and salinity (SSS) in reference to observations in the NE Baltic Sea by 22 % and 34 %, respectively, compared to the control run without DA. The method is based on the covariance estimates from the long period model data. The amplitudes of the pre-calculated gravest EOF modes are estimated from point observations using least-squares optimization; the method builds the variables on the regular grid. The study used FerryBox observations along four ship tracks from 1 May to 31 December 2015, and observations from research vessels. In the reconstruction, this data amount was compressed into daily averages over 5’ N X 10’ E coarse grid. Skill was tested based on daily averages on the 0.5’ N X 1’ E original fine grid of the model. DA with EOF reconstruction technique was found feasible for further implementation studies, since: 1) the method that works on the large-scale patterns (mesoscale features are neglected by taking only the gravest EOF modes) improves the high-resolution model performance by comparable or even better degree than in the other published studies, 2) the method is computationally effective.
Development of pedotransfer functions for water retention in tropical mountain soil landscapes: spotlight on parameter tuning in machine learning
Authors: Gebauer Anika , Ellinger Monja , Brito Gomez Victor M. , Ließ Mareike
Published: June 2020

Abstract. Machine-learning algorithms are good at computing
non-linear problems and fitting complex composite functions, which makes
them an adequate tool for addressing multiple environmental research questions.
One important application is the development of pedotransfer functions
(PTFs). This study aims to develop water retention PTFs for two remote
tropical mountain regions with rather different soil landscapes:
(1) those dominated by peat soils and soils under volcanic influence with high organic matter
contents and (2) those dominated by tropical mineral soils. Two tuning procedures were
compared to fit boosted regression tree models: (1) tuning with grid search,
which is the standard approach in pedometrics; and (2) tuning with
differential evolution optimization. A nested cross-validation approach was
applied to generate robust models. The area-specific PTFs developed outperform other more general PTFs. Furthermore, the first PTF for typical soils of
Páramo landscapes (Ecuador), i.e., organic soils under volcanic
influence, is presented. Overall, the results confirmed the differential
evolution algorithm's high potential for tuning machine-learning models.
While models based on tuning with grid search roughly predicted the response
variables' mean for both areas, models applying the differential evolution
algorithm for parameter tuning explained up to 25 times more of the response
variables' variance.
Snow depth estimation and historical data reconstruction over China based on a random forest machine learning approach

Published: June 2020

Abstract. We investigated the potential capability of the random forest (RF)
machine learning (ML) model to estimate snow depth in this work. Four
combinations composed of critical predictor variables were used to train the
RF model. Then, we utilized three validation datasets from out-of-bag (OOB)
samples, a temporal subset, and a spatiotemporal subset to verify the fitted
RF algorithms. The results indicated the following: (1) the accuracy of the
RF model is greatly influenced by geographic location, elevation, and land
cover fractions; (2) however, the redundant predictor variables (if highly
correlated) slightly affect the RF model; and (3) the fitted RF algorithms
perform better on temporal than spatial scales, with unbiased root-mean-square errors (RMSEs) of ∼4.4 and ∼7.3 cm,
respectively. Finally, we used the fitted RF2 algorithm to retrieve a
consistent 32-year daily snow depth dataset from 1987 to 2018. This product
was evaluated against the independent station observations during the period
1987–2018. The mean unbiased RMSE and bias were 7.1 and −0.05 cm,
respectively, indicating better performance than that of the former snow
depth dataset (8.4 and −1.20 cm) from the Environmental and Ecological
Science Data Center for West China (WESTDC). Although the RF product was
superior to the WESTDC dataset, it still underestimated deep snow cover
(>20 cm), with biases of −10.4, −8.9, and −34.1 cm for
northeast China (NEC), northern Xinjiang (XJ), and the Qinghai–Tibetan Plateau
(QTP), respectively. Additionally, the long-term snow depth datasets
(station observations, RF estimates, and WESTDC product) were analyzed in
terms of temporal and spatial variations over China. On a temporal scale,
the ground truth snow depth presented a significant increasing trend from
1987 to 2018, especially in NEC. However, the RF and WESTDC products
displayed no significant changing trends except on the QTP. The WESTDC
product presented a significant decreasing trend on the QTP, with a
correlation coefficient of −0.55, whereas there were no significant trends
for ground truth observations and the RF product. For the spatial
characteristics, similar trend patterns were observed for RF and WESTDC
products over China. These characteristics presented significant decreasing
trends in most areas and a significant increasing trend in central NEC.
Radar measurements of blowing snow off a mountain ridge
Authors: Walter Benjamin , Huwald Hendrik , Gehring Josué , Bühler Yves , Lehning Michael
Published: June 2020

Abstract. Modelling and forecasting wind-driven redistribution of
snow in mountainous regions with its implications on avalanche danger,
mountain hydrology or flood hazard is still a challenging task often lacking
in essential details. Measurements of drifting and blowing snow for
improving process understanding and model validation are typically limited
to point measurements at meteorological stations, providing no information
on the spatial variability of horizontal mass fluxes or even the vertically
integrated mass flux. We present a promising application of a compact and
low-cost radar system for measuring and characterizing larger-scale
(hundreds of metres) snow redistribution processes, specifically blowing
snow off a mountain ridge. These measurements provide valuable information
of blowing snow velocities, frequency of occurrence, travel distances and
turbulence characteristics. Three blowing snow events are investigated, two
in the absence of precipitation and one with concurrent precipitation.
Blowing snow velocities measured with the radar are validated by comparison
against wind velocities measured with a 3D ultra-sonic anemometer. A minimal
blowing snow travel distance of 60–120 m is reached 10–20 % of the
time during a snow storm, depending on the strength of the storm event. The
relative frequency of transport distances decreases exponentially above the
minimal travel distance, with a maximum measured distance of 280 m. In a
first-order approximation, the travel distance increases linearly with the
wind velocity, allowing for an estimate of a threshold wind velocity for
snow particle entrainment and transport of 7.5–8.8 m s−1, most
likely depending on the prevailing snow cover properties. Turbulence
statistics did not allow a conclusion to be drawn on whether low-level,
low-turbulence jets or highly turbulent gusts are more effective in
transporting blowing snow over longer distances, but highly turbulent flows
are more likely to bring particles to greater heights and thus influence
cloud processes. Drone-based photogrammetry measurements of the spatial snow
height distribution revealed that increased snow accumulation in the lee of the
ridge is the result of the measured local blowing snow conditions.
Betrayal Set Design: From Minimalism to Multimedia
Authors: Cole George
Published: June 2020

Betrayal marked a radical shift in style, form, and plot device, with Pinter abandoning a single set structure for multiple sets. This article aims to explore how directors and designers have approached the challenges and opportunities offered by the play's structure. The article will examine eight major UK productions—from the original 1978 National Theatre production to the 2019 Harold Pinter Theatre production—which demonstrate a multitude of approaches and interpretations when it comes to set design, from naturalistic to multimedia to minimalism. The article will include accounts from designers and directors, and also critical reaction to the set designs. It will be argued that the creative flexibility offered by Betrayal's dramatic structure means that the play will continue to be staged in new, fresh and innovative ways.

Published: June 2020

In Independent Judgment and Introspection: Fundamental Requirements of the Free Society, Jerry Kirkpatrick maintains that a free society can exist only when a sufficient number of people have healthy psycho-epistemologies. He identifies fundamental aspects in our culture that work against this end. Building on the work of Objectivist psychologist Edith Packer, he presents a process for improving one's psycho-epistemology. Kirkpatrick also traces the history of child-rearing practices and relates the process of change to the work of many other psychologists including Horney, Freud, Ellis, and Rogers.

Published: June 2020

As moedas virtuais (ou criptomoedas) estão se tornando cada vez mais competitivas no mercado mundial, oque atrai investidores a obter lucros sobre as oscilações deste mercado. Esses investimentos são orientados por um princípio simples: comprar as moedas quando seu valor de mercado estiver prestes a subir, e vendê-las moedas quando estiverem prestes a perder o valor. O Objetivo deste trabalho é desenvolver um modelo de predição do movimento de preços de criptomoedas que utilize como base a percepção pública da população em relação às moedas. Foram realizadas predições tanto utilizando sentimento de notícias quanto sentimento de tweets, e o útlimo obteve melhores resultados, apresentando MDA de 73% no modelo criado com XGBoost, sendo capaz de prever os resultados também em períodos de grandes oscilações. Supõe-se que os melhores resultados foram obtidos a partir de sentimentos de tweets devido ao maior volume de dados gerado em um único dia, e devido à velocidade com a qual a manifestação pública é evidenciada na rede social.

Objetivo: Describir las tendencias de la mortalidad por cáncer oral entre 2000 y 2017 por sexos en 20 países de América Latina, e identificar los efectos de las políticas implementadas para controlar de los factores de riesgo. Materiales y métodos: Se realizó un estudio ecólogico que evaluó la relación entre las tasas estandarizadas por edad de mortalidad por cáncer oral según el sexo, la prevalencia de tabaquismo y consumo de alcohol y la implementación de las políticas públicas de control. Resultados: Los hombres de Cuba y Brasil muestran las más altas tasas de mortalidad en la región. Los descensos más importantes se presentan en los hombres de Brasil y en las mujeres de Panamá. Son pocas las tendencias al aumento, aunque éstas se evidencian especialmente entre las mujeres. La implementación de las medidas de control de factores de riesgo, en cuanto a tabaco, alcohol, infecciones virales, programas de detección temprana y tratamiento, muestra avances desiguales entre los países. Se observó una mayor relación entre la mortalidad por cáncer oral con el consumo de tabaco en los contextos de menor implementación de las políticas, y el consumo de alcohol en los escenarios de mayor avance. Conclusión: La mortalidad por cáncer oral afecta especialmente a los hombres de la región, lo que se puede asociar a la distribución de los factores etiológicos y avances desiguales de los países en la implementación de las medidas preventivas. Se requiere profundizar en investigación subnacional de seguimiento, y fortalecer la prevención y tratamiento con estrategias validas para cada contexto.

The Covid-19 pandemic has had negative effects throughout the whole world, including education systems. To overcome this negativity, all educational institutions have turned to internet-based education. However, the educator’s self-efficacy is of more importance in this system. This study aimed to reveal the connection between the University academic staff’s genders, ages, titles (doctorate/non-doctorate), and work year characteristics and their self-efficacy beliefs about their educational Internet usage. The sample consists of 100 [51% (n = 51) female and 49% (n = 49) male] academic staff, who were selected according to convenience sampling in the Faculty of Education and Faculty of Sport Sciences at Uludag University. In this study, the “Educational Internet Usage Self-Efficacy Beliefs” scale, developed by Şahin (2009), was used to collect data. Descriptive statistics refer to number and percentage for qualitative variables; quantitative variables are summarized using mean, median, standard deviation, and minimum and maximum statistics. Univariate analyses used binary group comparisons with the Student’s t-test and relationships between numerical variables and Spearman correlation coefficients. Multiple regression analysis was used, in conjunction with the backward method, for the multivariate linear regression method. Analysis results alpha (Type I error) value was evaluated at the level of 0.05 significance. The mean level of self-efficacy belief of academic staff is 109,42. Since the highest score that can be obtained from the scale is 140, the relationships between scale score and age and duration of service variables are significant according to the univariate analysis, while differences in gender and PhD and non-PhD groups are not significant. When multiple linear regression analysis is applied with the backward stepwise method, age and academic title variables are significant in the model. Additionally, the mean scale scores of PhD academicians are higher than others.

The research area is located in the territory of Khatanbulag soum, Dornogovi province, in the Great Govi Province (coordinates: 108°25'39.04"E and 43°10'11.43"N). Here, the authors studied the composition of sediments that had previously been classified as Lower Cretaceous Khukhteeg Formation, forming Mt. Ergel-Khaliv during earlier mapping work. The authors revealed fossils of faunas and floras, processing some data of biostratigraphic survey works taken on fossil-bearing sediments of the area. The fieldwork was conducted in April 2019 by researchers from the Institute of Paleontology, Mongolian Academy of Sciences. The area is very rich in fossils of mollusca, therefore, the local communities named it Dun-Ovoo (Conch hill). During the previous studies, the sediments outcropping around the Ergel-Khaliv were classified as Khukhteeg Formation (K1ht, Aptian-Albian) based on lithological characteristics and comparing them to the type section of the Khukhteeg Formation sediments. Our research revealed biostratigraphic basements and recorded previous data of collected fossils two types of mollusca; we have studied plant fossils, turtles, ostracods, fish and dinosaur bones had been revealed at first in that area. The results of the research work, the fossils that found in the mountain, were amended by more and new types and families of fauna and flora and their constituents. These new findings were helpful in the precise determination of the age of the sediments and provided some information on the paleoenvironmental conditions of the sedimentation period.
Petrology and mineralogy of the Ulaan Del Zr-Nb-REE deposit, Lake Zone, Western Mongolia
Authors: Oyunbat Sanjsuren
Published: June 2020

The Ulaan Del deposit is located in the Lake Zone, Western Mongolia. In the area, middle-late Devonian alkali dykes of the Khalzan Complex are hosted in the middle-late Cambrian granodiorite-tonalite of the Togthohiinshil Complex. The alkali dykes of the Khalzan complex comprise medium- to fine-grained syenite, microsyenite, syenite-porphyry and trachyte, trachyrhyolite, and trachyandesite. The dykes are replaced to silica, sericite, albite, fluorite and are brecciated. They crosscut by quartz and quartz-carbonate veinlets. The dykes contain zircon (>0.19% Zr) with a total of rare earth elements oxides >0.1%. The host rocks of the Togtokhiinshil complex are mid-K, metaluminous, I- type granite, depleted in HFSE. Based on geochemical and mineralogical data, economic REE mineralization is concentrated in syenite and syenite porphyry of calc-alkaline high K to shoshonite series of A- type granite, emplaced at within a plate setting. Syenite dykes are enriched in REE. Ore minerals are zircon, apatite, sphene, monazite, xenotime, synchysite, parisite, fluorite and REE complex minerals, pyrite, rutile and limonite. Magmatic, metasomatic and hydrothermal processes significantly contributed to the formation of Zr, Nb, REE and Y mineralization at the Ulaan Del deposit.

Ao identificar casos de sucesso na alfabetização em território vulnerável e ancorada em estudos que mostram a influência do território vulnerável na aprendizagem dos alunos (BATISTA; CARVALHO-SILVA, 2013; CENPEC, 2011; ERNICA; 2012), esta pesquisa buscou responder à questão: quais fatores levam uma escola situada em território vulnerável a apresentar maior percentual de alunos no nível avançado em alfabetização nas provas do PROALFA. O método de pesquisa foi um estudo de caso, com análise documental, observação e entrevistas com profissionais da escola e familiares dos alunos. A unidade de estudo foi a Escola Municipal Professora Laura Fabri que, entre 19 escolas municipais de Governador Valadares-MG, apresentou melhor desempenho no PROALFA, entre 2014 e 2016. Dos cinco mecanismos que explicam as razões do sucesso da escola em alfabetização, nesse artigo, serão abordados os dois que colocam em evidência o efeito da atuação do pedagogo: coordenação das práticas de alfabetização e formação continuada.

Published: June 2020

Este artigo tem como objetivo analisar os sentidos que emergem do discurso de professores e professoras em processo de formação continuada centrada na escola sobre os saberesfazeres do coordenador pedagógico. Utilizamos como caminho metodológico a Análise do Discurso na perspectiva utilizada por Orlandi. Os dados foram construídos a partir da utilização de entrevistas semiestruturadas realizadas com nove professores do ensino médio da rede estadual de ensino do município de Vitória de Santo Antão (PE). Os achados da pesquisa revelam sobretudo que os sentidos sobre os saberesfazeres do/a coordenador/a pedagógico/a se articulam, principalmente, à lógica gerencialista e da performatividade afetando intensamente o cotidiano das escolas e os modos de ser e estar docente.

Published: June 2020

O objeto do estudo é a formação continuada do coordenador pedagógico de uma rede municipal de ensino. O problema de investigação indaga: quais as possibilidades e os limites da formação continuada para a realização do trabalho do coordenador pedagógico nas escolas municipais? A pesquisa de cunho qualitativo pautou-se na análise de conteúdo (BARDIN, 2010) de documentos legais do município e realização de entrevistas semiestruturadas com 10 coordenadores pedagógicos. A concepção de formação continuada fundamenta-se no eixo epistemológico da teoria como expressão da prática (MARTINS, 1996). Os resultados indicam: a) possibilidades: formação para o iniciante na função; definição do papel de formador dos professores; troca de experiências; b) limites: formação distanciada das necessidades da escola e do protagonismo docente; definição da função do coordenador pedagógico alinhada aos moldes da sociedade capitalista.
