PETROZAVODSK – CUNEO TELECONFERENCE: NEW FACETS OF ICT USE IN RCT TRAINING
Authors: Алешина А.Б. , Булгарелли Е.Д. 
Published: July 2020

В данной статье авторы делятся опытом проведения телемостов между изучающими РКИ в школе Enjoy Russian в г. Петрозаводске и студентами Высшей школы языкового посредничества Adriano Macagno в г. Кунео. Цель таких мероприятий – желание педагогов разнообразить аппарат коммуникативных упражнений, применяемых ими в обучении, а также повысить мотивацию у учащихся, в особенности у студентов, изучающих русский в Италии, где зачастую недостаточно возможностей для естественной речевой практики. Задачей телемостов стало создание ситуаций живого общения с заданными целями, стимулирующими участников к активному использованию языковых средств, усвоенных ранее в рамках пройденной темы. Общение с незнакомыми людьми, которые также изучают русский язык, но в другой стране послужило мотивирующим фактором, побуждающим искренний интерес к обмену информацией и желание узнать о собеседнике как можно больше. В рамках данной статьи подробно описываются преимущества и недостатки телемостов, особенности их проведения. Характеризуется не только формат общения участников через программу Skype, но и другой, не столь популярный в сфере обучения иностранным языкам вид дистанционного общения – обмен аудиосообщениями посредством мобильного приложения WhatsApp.
In the article, the authors share their experience in conducting teleconferences between the students, who study Russian language at Enjoy Russian in Petrozavodsk and Adriano Macagno high school in Cuneo. The goal of the teleconferences was to diversify communicative exercises the teachers use, and to increase students’ motivation, especially Italian students, because in Italy, there are usually not enough opportunities for speaking practice in Russian. Teleconferences were meant to create situations of natural communication with some objectives that stimulated the participants to actively use the language tools (vocabulary and grammar) that they have learned before. Communication with strangers that are also learning the Russian language, but in another country, was for sure a motivating factor that indulged a sincere interest towards exchanging the information and finding out as much as possible about the partner. In this article, the authors describe in details advantages and disadvantages of teleconferences, their special features. The authors do not only characterize distant communication through Skype, but also not such a popular tool among teachers of Russian as a foreign language – WhatsApp audio files exchange.
Negative Magnetic Diffusivity β Replacing the α Effect in the Helical Dynamo
Authors: Park Kiwan 
Published: July 2020

Abstract
In the Sun, the converting process of a poloidal magnetic field (
B

pol) from a toroidal field (
B

tor) is essential to sustaining the solar magnetic fields. However, the converting process, dominated by α and β effects, is not yet clearly understood. Conventional theories expect that the α effect should be quenched as the magnetic field grows. Also, plasma kinetic energy is thought to diffuse magnetic energy (positive β effect). Then,
B

pol is supposed to decay resulting in the dissipation of
B

tor, followed by the diminishing dynamo process. But the solar magnetic field evolves periodically, as is observed. To solve this inconsistency between the theory and real nature, we first need to check if the α and β effects indeed evolve as the conventional theories expect. However, these effects are theoretically or conceptually inferred quantities, and their exact expressions are not yet known. So, instead of their incomplete formulas, we used more practical representations composed of large-scale magnetic helicity

and energy

. We verified that the α effect quenches as the conventional theory expects. However, we also found that the β effect can be negative. This negative β apparently looks inconsistent with the conventional conclusion, but it can be a promising substitution for the decaying α effect. We discuss their physical bases and mechanisms using a field structure model supported by an analytic method. The model shows that the interaction between the poloidal velocity component (
U

pol) and nonlocally transferred magnetic field (
B
· ∇
U
) induces a current density
j

ind along with the magnetic field. Their combined structure yields magnetic helicity to the system, which is the α effect. However,
U

pol can also interact with the locally transferred magnetic field, i.e.,
U

pol × (−
U
· ∇
B
) inducing a current density
j

diff. This current density can produce additional magnetic helicity (negative β effect) to the system. Simultaneously, the toroidal component
U

tor with −
U
· ∇
B
leads to the usual positive β effect, which diffuses the magnetic field. Finally, using the negative β effect, we show how the plasma motion is suppressed in a helically forced dynamo system where Lorentz force (
J

) apparently looks negligible.
Nuclear X-Ray Activity in Low-surface-brightness Galaxies: Prospects for Constraining the Local Black Hole Occupation Fraction with a Chandra Successor Mission
Authors: Hodges-Kluck Edmund J. , Gallo Elena , Seth Anil , Greene Jenny , Baldassare Vivienne 
Published: July 2020

Abstract
About half of nearby galaxies have a central surface brightness ≥1 mag below that of the sky. The overall properties of these low-surface-brightness galaxies (LSBGs) remain understudied, and in particular we know very little about their massive black hole population. This gap must be closed to determine the frequency of massive black holes at z = 0 as well as to understand their role in regulating galaxy evolution. Here we investigate the incidence and intensity of nuclear, accretion-powered X-ray emission in a sample of 32 nearby LSBGs with the Chandra X-ray Observatory. A nuclear X-ray source is detected in four galaxies (12.5%). Based on an X-ray binary contamination assessment technique developed for normal galaxies, we conclude that the detected X-ray nuclei indicate low-level accretion from massive black holes. The active fraction is consistent with that expected from the stellar mass distribution of the LSBGs, but not their total baryonic mass, when using a scaling relation from an unbiased X-ray survey of normal galaxies. This suggests that their black holes co-evolved with their stellar population. In addition, the apparent agreement nearly doubles the number of galaxies available within ∼100 Mpc for which a measurement of nuclear activity can efficiently constrain the frequency of black holes as a function of stellar mass. We conclude by discussing the feasibility of measuring this occupation fraction to a few percent precision below ≲1010

Successfully delayed delivery of second twin after early second trimester rupture of membranes of the first twin: a case report
Authors: Georgievska Jadranka , Samardziski Igor , Daneva Ana , Kocoski Goran 
Published: July 2020

Twin pregnancies are high-risk pregnancies accompanied with multiple complications, such as: spontaneous abortion, preterm rupture of the membranes, preterm delivery, intrauterine death of one or both twins etc. There is no consensus about the management of twin pregnancies complicated with preterm rupture of the membranes of one twin and risk of preterm delivery. These cases are rarely found in the literature. We present a case of a 35 years old patient, hospitalized in a tertiary level institution, because of a diamniotic dichorionic twin pregnancy complicated with preterm rupture of the membranes of the first twin at 19 weeks of gestation. She had one delivery with Caesarean section 16 years ago. In consultation with the patient induction of labor was done with delivery of the first twin, a death male fetus. After that, antibiotics and tocolytic therapy were administrated and the patient remained in the hospital about one week. The patient was discharged at home with regular control of her condition and condition of the fetus. The patient was again hospitalized at 33 weeks of gestation with uterine contractions on cardiotocography. After administration of corticosteroid therapy for fetal lung maturation she delivered spontaneously the second twin in a good condition and she was discharged from hospital after 16 days. In twin pregnancies clinicians must think about delayed interval delivery of the second twin, after delivery of the first twin, with an aim to increase chances for survival, especially for pregnancies less than 30 weeks of gestation.

Abstract
There is currently no clinically effective vaccine against cutaneous leishmaniasis because of poor understanding of the Ags that elicit protective CD4+ T cell immunity. In this study, we identified a naturally processed peptide (DLD63–79) that is derived from Leishmania dihydrolipoyl dehydrogenase (DLD) protein. DLD is conserved in all pathogenic Leishmania species, is expressed by both the promastigote and amastigote stages of the parasite, and elicits strong CD4+ T cell responses in mice infected with L. major. We generated I-Ab-DLD63–79 tetramer and identified DLD-specific CD4+ T cells at clonal level. Following L. major infection, DLD63–79–specific CD4+ T cells massively expanded and produced effector cytokines (IFN-γ and TNF). This was followed by a gradual contraction, stable maintenance following lesion resolution, and display of memory (recall) response following secondary challenge. Vaccination with rDLD protein induced strong protection in mice against virulent L. major challenge. Identification of Ags that elicit protective immunity and their responding Ag-specific T cells are critical steps necessary for developing effective vaccines and vaccination strategies against infectious agents, including protozoan parasites.
Development and Validation of a Theory-Informed Group Learning Environment Assessment Tool for Graduate Medical Education Programs
Authors: Welch Cristina E. , Carbajal Melissa M. , Kumar Shelley , Thammasitboon Satid 
Published: July 2020

ABSTRACT

Background
Recent studies showed that psychological safety is important to resident perception of the work environment, and improved psychological safety improves resident satisfaction survey scores. However, there is no evidence in medical education literature specifically addressing relationships between psychological safety and learning behaviors or its impact on learning outcomes.

Objective
We developed and gathered validity evidence for a group learning environment assessment tool using Edmondson's Teaming Theory and Webb's Depth of Knowledge model as a theoretical framework.

Methods
In 2018, investigators developed the preliminary tool. The authors administered the resulting survey to neonatology faculty and trainees at Baylor College of Medicine morning report sessions and collected validity evidence (content, response process, and internal structure) to describe the instrument's psychometric properties.

Results
Between December 2018 and July 2019, 450 surveys were administered, and 393 completed surveys were collected (87% response rate). Exploratory factor analysis and confirmatory factor analysis testing the 3-factor measurement model of the 15-item tool showed acceptable fit of the hypothesized model with standardized root mean square residual = 0.034, root mean square error approximation = 0.088, and comparative fit index = 0.987. Standardized path coefficients ranged from 0.66 to 0.97. Almost all absolute standardized residual correlations were less than 0.10. Cronbach's alpha scores showed internal consistency of the constructs. There was a high correlation among the constructs.

Conclusions
Validity evidence suggests the developed group learning assessment tool is a reliable instrument to assess psychological safety, learning behaviors, and learning outcomes during group learning sessions such as morning report.

It featured open-ended questions, with neither a right nor a wrong answer. Questions such as: should everything be automated?
With this question Design Does* presented the piece Death Inc., a reflection on design applied to the arms industry. The exploration of a new style of killing that arises from the incorporation of image recognition technologies to military robots. The death of a human by a machine’s hands and decision.
Landscape Design Methodology: Pattern formation through the use of Cellular Automata
Authors: Abellán Sanfélix Sergi , Bilurbina Camps Marcel , Christodoulou Marilena 
Published: July 2020

The purpose of this study is to develop a landscape design methodology based on the use of a Cellular Automaton (CA) algorithm in order to introduce the plant-plant interaction factor in the plantating design of a site. This design methodology introduces the relationships between neighboring individuals of different species as parameters for the project. These parameters are codified in order to define the Cellular Automaton rules. Parameters related to the growth and morphologic characteristics of the species as well as programmatic and aesthetic parameters of the project may be introduced as rules that influence the behavior of the CA algorithm.
The algorithm developed is called NNB-CA (Natural Neighbouring Behaviour Cellular Automata) and it is based on John Conway’s original “Game of Life” CA. The design methodology takes in account site conditions and is developed in two phases. In the first one, starting with a list of species, a preselection of species is done taking into account the site’s parameters and it defines which species are able to populate on each area of the discretized site. In the second phase, the CA algorithm is run applying the relational rules with the selected species. This iterative process is applied until it reaches an equilibrium state.
Rules related to the competition between species according to their growing characteristics are studied comparing an analog/natural evolutive process using rapidly developing plants and the corresponding digital process that simulates the analog one.

Published: July 2020

Esse artigo é recorte de uma pesquisa de mestrado acadêmico que adota a noção de transposição didática de Yves Chevallard e objetiva analisar aspectos relacionados ao processo de transposição didática interna da operação de divisão de números naturais no Ensino Fundamental. Para subsidiar a análise das aulas de Matemática de três professores, foi realizado um estudo dos documentos legais do Brasil e do Estado de Pernambuco, análise de livros didáticos para o 4º, 5º e 6º anos e entrevistas com os professores que atuam nesses anos escolares. Nas aulas, o foco de análise foram os diferentes significados da divisão, os procedimentos de cálculo, o tratamento dado ao resto e à interpretação dos resultados obtidos, abordados ou não nas aulas observadas. Ao comparar o saber previsto para ser ensinado e o saber efetivamente ensinado verificou-se mudanças, deformações e lacunas, que poderiam acarretar dificuldades no processo de aprendizagem da operação.

La COVID-19 ha irrumpido en la vida de los seres humanos causando efectos devastadores en la salud y en la vida de gran parte de la población mundial, afectando a las esferas sociales, económicas y educativas del planeta. La comunidad científica se encuentra ante uno de sus mayores retos para resolver un problema sanitario de alcance global como es la pandemia del COVID-19. Esta situación ha generado un volumen de publicaciones sin precedentes. El impacto del COVID-19 en la enseñanza ha supuesto que los momentos de contacto social hayan desaparecido a cambio de reuniones, clases, exámenes o encuentros virtuales. En este escenario, las aulas universitarias al volver a abrirse no serán las mismas, tampoco sus campus ni espacios del ámbito educativo. El objetivo del estudio fue identificar las publicaciones científicas relacionadas con los efectos del COVID-19 en las aulas universitarias durante el período 2019 hasta la actualidad. Para esto, se realizó un análisis bibliométrico de la literatura científica. Se identificaron 676 documentos sobre esta temática. Los resultados del análisis revelaron que la productividad científica se ha incrementado desde enero de 2020 con más de 650 artículos sobre la enfermedad, verificando el profundo interés por el COVID-19 en todas las disciplinas. Las principales tendencias de investigación incluyen el impacto de la vuelta a las aulas con los efectos en los procesos cognitivos, motivaciones y del rendimiento académico de los estudiantes.

Salah satu fungsi pendidikan adalah membangun karakter bangsa yang harus tetap dipertahankan. Begitu pula perlu dikembangkan nilai-nilai yang dikategorikan high-trust seperti Etika Pancasila menjadi fundamental bangsa dalam rangka penguatan integritas para penyelenggara negara atau pejabat publik jelas perlu penguatan etika. Etika umumnya dipahami sebagai ‘teori atau ilmu tentang praktik moral. Sedanglkan Etika Pancasila secara normatif dapat dijadikan sebagai suatu acuan atas tindakan baik, dan secara filosofis dapat dijadikan perspektif kajian atas nilai dan norma yang berkembang dalam masyarakat. Namun, sebagai suatu kesatuan nilai yang utuh, nilai-nilai tersebut memberikan ciri khusus pada ke-Indonesia-an. Pancasila sebagai dasar etika dalam kehidupan bermasyarakat, berbangsa, dan bernegara diberdayakan melalui kebebasan akademik untuk mendasari suatu sikap mental atau attitude. Kebebasan akademik adalah hak dan tanggung jawab seseorang akademisi. Hak dan tanggung jawab itu terkait pada moral akademik

Abstract
Date Presented 03/26/20
This study examined the impact of AT paired with individualized support on occupational engagement in higher education (HE). Findings indicate that individualized support paired with AT use increases self-efficacy and continued engagement with AT. This data shows that individualized support by an OT paired with AT may decrease AT abandonment and enhance academic occupational engagement in HE, specifically in self-reported academic performance and satisfaction.
