Coronavirus disease 2019-associated mucormycosis – A syndemic
Authors: Priyadarshi Megha , Praveen Tirlangi , Mittal Ankit , Singh Gagandeep , Xess Immaculata , Wig Naveet
Published: October 2021

Coronavirus disease 2019 (COVID-19) and COVID-associated mucormycosis (CAM) came as a syndemic that not only severely increased morbidity and mortality but also posed a serious challenge for the healthcare system of a developing country like India. Although mucormycosis is a rare disease with a worldwide incidence of 0.43 cases per million population/year, these two COVID-19 waves caused a total of more than 14,000 cases in India itself. Mucormycosis is an angio-invasive fungal infection with rapid progression. The three major modalities of treatment involve early surgical debridement, initiation of antifungal therapy and controlling the predisposing risk factor. A complex interplay of factors, including pre-existing disease such as diabetes mellitus, use of immunosuppressants and immunomodulators, risk of hospital-acquired infection and immune dysregulation post-COVID-19, may all predispose to the development of CAM. Future research regarding the efficiency of newer antifungal with lower side effect profiles and evidence-based establishment of risk factors for adopting preventing strategies is the need of the hour. The disease is known to have high mortality despite the best treatment. We review in this article the aetiopathogenesis, various diagnostic modalities and treatment considerations for this disease.
Porokeratotic eccrine ostial and dermal duct nevus
Authors: Kumar S. Sudheer , Kumar K. Ram , Chenchaih V. , Usha Grandhi , Ramana P. Venkata
Published: October 2021

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is an uncommon benign disorder that clinically mimicks comedo nevus but usually favors the palms and soles, where pilosebaceous follicles are absent. It also can present with widespread involvement along Blaschko's lines. It is a disorder of keratinisation involving the intraepidermal eccrine duct (acrosyringium) with classical histopathological examination findings (eccrine hamartoma and cornoid lamellation). The patient is a 32-year-old woman with a 12-year history of pruritic skin lesions on her right palm and index finger. Histopathological examination revealed multiple small epidermal invaginations with overlying parakeratotic cornoid lamellation and loss of granular layer. Few dyskeratotic cells are seen at the base of epidermal invagination. After clinic-pathologic correlation, the diagnosis of PEODDN was made. Late-onset and rare clinical presentation as pruritic lesion are the characteristic features that make this patient an extraordinary presentation of PEODDN.

Published: October 2021

Background:

Patients diagnosed to have active tuberculosis (TB) may have co-existing comorbid conditions. Treatment for both conditions may lead to possible drug-related problems. Hence, the present study was designed to understand the incidence and pattern of drug-related problems. This knowledge gives a scope to minimise the occurrence and help patients to adhere to treatment.

Methods:

A prospective observational study was carried out for a period of 6 months. A pre-designed data collection form was used for this study that was used to document clinical data including brief history, laboratory investigations, treatment details and drug-drug interactions (DIs).

Results:

One hundred and five TB patients were enrolled in the study. Their mean age was 43.7 ± 16.8 years. Sixty patients were found to have comorbidities. One hundred and fifty-eight drug-related problems between comorbidities' treatment regimens and ATT were documented. DIs were the most common drug-related problems. Seventy-nine major DIs and 74 moderate DIs were documented. Nine patients had adverse drug reactions which were ATT-induced hepatotoxicity, thrombocytopenia and anaemia.

Conclusions:

Co-existence of comorbidities and their treatment resulted in a significant burden on patients who are diagnosed positive for TB. This can lead to treatment delay or failure or default. Strategies and programmes to tackle the burden of comorbid conditions on TB-positive patients are to be developed and implemented aggressively.
A polynomial excluded-minor approximation of treedepth
Authors: Kawarabayashi Ken-ichi , Rossman Benjamin
Published: October 2021

Treedepth is a minor-monotone graph invariant in the family of “width measures” that includes treewidth and pathwidth. The characterization and approximation of these invariants in terms of excluded minors has been a topic of interest in the study of sparse graphs. A celebrated result of Chekuri and Chuzhoy (2014) shows that treewidth is polynomially approximated by the largest

k \times k

grid minor in a graph. In this paper, we give an analogous polynomial approximation of treedepth via three distinct obstructions: grids, balanced binary trees, and paths. Namely, we show that there is a constant

c

such that every graph with treedepth

\Omega(k^c)

has at least one of the following minors (each of treedepth at least

k

):

Moreover, given a graph

G

we can, in randomized polynomial time, find an embedding of one of these minors or conclude that treedepth of

G

is at most

O(k^c)

. This result has applications in various settings where bounded treedepth plays a role. In particular, we describe one application in finite model theory, an improved homomorphism preservation theorem over finite structures [Rossman, 2017], which was the original motivation for our investigation of treedepth.
New solution of a problem of Kolmogorov on width asymptotics in holomorphic function spaces
Authors: Bandtlow Oscar F. , Nivoche Stéphanie
Published: October 2021

Given a domain

D

in

\mathbb{C}^n

and a compact subset

K

of

D

, the set

\mathcal{A}_K^D

of all restrictions of functions holomorphic on

D

the modulus of which is bounded by

is a compact subset of the Banach space

C(K)

of continuous functions on

K

. The sequence

(d_m(\mathcal{A}_K^D))_{m\in \mathbb{N}}

of Kolmogorov

m

-widths of

\mathcal{A}_K^D

provides a measure of the degree of compactness of the set

\mathcal{A}_K^D

in

C(K)

and the study of its asymptotics has a long history, essentially going back to Kolmogorov’s work on

\epsilon

-entropy of compact sets in the 1950s. In the 1980s Zakharyuta showed that for suitable

D

and

K

the asymptotics

\lim_{m\to \infty}\frac{- \log d_m(\mathcal{A}_K^D)}{m^{1/n}} = 2\pi \bigg( \frac{n!}{C(K,D)} \bigg) ^{1/n},

where

C(K,D)

is the Bedford–Taylor relative capacity of

K

in

D

, is implied by a conjecture, now known as Zakharyuta's Conjecture, concerning the approximability of the regularised relative extremal function of

K

and

D

by certain pluricomplex Green functions. Zakharyuta’s Conjecture was proved by Nivoche in 2004 thus settling (1) at the same time.

We shall give a new proof of the asymptotics (1) for

D

strictly hyperconvex and

K

non-pluripolar which does not rely on Zakharyuta’s Conjecture. Instead we proceed more directly by a two-pronged approach establishing sharp upper and lower bounds for the Kolmogorov widths. The lower bounds follow from concentration results of independent interest for the eigenvalues of a certain family of Toeplitz operators, while the upper bounds follow from an application of the Bergman–Weil formula together with an exhaustion procedure by special holomorphic polyhedra.

Authors: Ocana-Mayorga Sofia , Bustillos Juan J. , Villacís Anita G. , Moncayo Ana L. , Yumiseva Cesar A. , Brenière Simone F. , Grijalva Mario J.
Published: October 2021

Transmission risk of Chagas disease has been associated with human-vector contacts and triatomines colonizing dwellings, but alternative scenarios, independent of domestic colonization, are poorly documented. In the present work, we estimated the frequency of human blood meals in triatomines from domicile, peridomicile, and sylvatic environments in two endemic regions in Ecuador. Blood meal origins were identified by sequencing a cytb gene fragment. Human blood meals were detected in 42% of the triatomines among 416 analyzed, including 48% of sylvatic triatomines (both adults and nymphs). In triatomines from domicile and peridomicile, Trypanosoma cruzi infection rate was > 20%, and reached 48% in sylvatic triatomines. Human is a common source of blood for triatomines whether they live in or near dwellings in both regions, and the high rate of T. cruzi infection represents an important risk of transmission of Chagas disease. Consequently, control strategies should also take into account possible nondomestic transmission.

Published: October 2021

The paper is devoted to the critical analysis of the radiocarbon dating results of Mesolithic, Neolithic and Chalcolithic complexes of the northeastern part of the East European Plain (Republic of Komi, Arkhangelsk and Vologda Regions and the Nenets Autonomous Area, Russian Federation). The comprehensive evaluation of all available geochronometric data in relation with the studied archaeological events highlighted the following three data sets: reliable, ambiguous and invalid dates. A new chronological model of Far Northeast of Europe colonization and dispersal of innovations over the Holocene is proposed based upon reliable radiocarbon dating results.

ABSTRACT. A series of metal complexes [Co(HL)2(H2O)2]Cl2.5H2O (A), [Cu(HL)2](CH3COO)2.2H2O (B), [Y(HL)2]Cl3.2H2O (C), [ZrO(HL)2H2O]Cl2.H2O (D), [La(HL)2(H2O)2]Cl3.5H2O (E) and [UO2(HL)2](CH3COO)2 (F) were prepared. The structures of the compounds in solid state were detected by micro analytical, Fourier transform IR, 1H NMR, UV-Vis, mass, X-ray diffraction spectra, molar conductivity, magnetic susceptibility measurements and TG/DTG analysis. The IR spectral data point out that the ligand behaves as tridentate in nature with Cu(II), Y(III), U(VI) and bidentate with Co(II), Zr(IV) and La(III) metal ions. The conductivity values showed that the complexes found as electrolytes and the XRD models of the complexes indicated crystalline nature. The thermodynamic parameters of compounds have been detected using Coats-Redfern and Horowitz-Metzeger methods at n = 1 and n ≠ 1 and values point out more ordered activated complex formation. The nematicidal efficacy of compounds was assessed.

Mechanizmy karier na dworach kobiecych w Wersalu w drugiej połowie XVIII wieku
Authors: Kuras Katarzyna
Published: October 2021

The career mechanisms at the women’s courts in Versailles in the second half of the 18th century

The purpose of the article is to examine the career mechanisms at the royal court in Versailles mainly in the 60s and 70s of the 18th century in reference to the households (maisons) of Queen Marie Leszczyńska (d. 1768) and Dauphine Marie Josephe of Saxony (d. 1767). The structures and sustainability of these households went beyond the usual patterns as a result of accidental circumstances and ad hoc decisions taken by King Louis XV. The accumulation of problems and surprising circumstances forced him to take non-stereotypical actions. Reforms – even the smallest ones – revealed additionally the signs of crisis, which was systematically increasing at the entire court in Versailles. As a result, in the second half of the 18th century, the modernization of the court was also a sign of its serious crisis, and the careers of maisons’ officials were directed by new mechanisms that had previously not existed.
Kampania polska 1939 roku. Przegląd koncepcji i sposobów jej prezentacji w historiografii i edukacji historycznej XX wieku

Published: October 2021

The Polish campaign of 1939 in historiography and historical education of the 20th and 21st centuries, in selected aspects

The article is part of a publication series devoted to the terminological and historiographic aspects of the Polish campaign of 1939. A completely new approach to this important event is the focus on its presence in historical education of the 20th and 21st century. The Polish Campaign of 1939 has held a special place in the historiographic narrative and school curricula alike. Its depictions – both academic and popular-scientific – have been and still remain compatible with each other. At certain times however – especially during the ideological assault of the 1950s – historical education diverged from historiography, creating an anti-German and pro-Soviet image. After 1989, the narrative of the Polish campaign of 1939 changed significantly and the “forgotten threads” were also introduced. This event still occupies a leading place in the so-called historical policy. It has also been put on a pedestal in historical education of school students, although for a period of several years in the early 21st century it was largely absent due to the limited number of topics from the recent history included in the school curriculum.
The Evacuation and Flight of Galician Refugees in the Habsburg Empire During the First World War – an Analysis of the Relocation System
Authors: Ruszała Kamil
Published: October 2021

As a result of war hostilities which began in the Habsburg Monarchy in 1914, migrations of the civilian population started, resulting from the movement of war refugees from the eastern front, i.e. Galicia, and also since May 1915 from the Italian front. Austria-Hungary had to face relocation and accommodation of hundreds of thousands of civilians, who were put in special refugee camps or outside of them in various towns and cities in the monarchy while being housed with their residents or in specially adapted buildings. The article shows selected aspects of the system of barrack camps created during the World War I in the Habsburg Monarchy, focusing on the efficiency of the system in the face of real challenges of the war period.

War refugees of the World War I in paintings and drawings from the Western Russian Provinces
During the World War I millions of civilians all around Europe and the Near East were often forced to leave their homes unprepared and in desperate hope of finding safety and refuge in distant lands. From the very beginning of the war, refugees became the topic and subject for both propagandists and artists alike. For the purposes of this article, a selected number of examples of drawings and paintings, presenting perspectives of Latvian, Polish and Jewish subjects of the tsar, have been chosen. In the iconography, war refugees are generally presented as innocent and helpless victims of the conflict, and as a proof of the brutality and barbarity of the unfolding hostilities. The article also explores the way artists honed in on the depictions of crying women; troubled and helpless old men; small children snuggling up to their mothers and people contending with hunger, cold, fear, disease, uncertainty of the future and longing for lost homes as well as separated family members. Very often, the typical backgrounds for such scenes are ruins and burning buildings. The artists who depicted the war refugees’ fate did not always share such dramatic experiences personally. However, they clealy acknowledged the fact that it played a huge role in forming the identity of the nations they belonged to.

Refugees’ Troubles or Trouble with Refugees? The DPS as Featured in the Polish Daily & Soldier’s Daily between 1945 and 1948
The article presents issue of the Polish displaced persons on the territory of the former Third Reich in light of coverage in the The Polish Daily & Soldier’s Daily newspaper (Dziennik Polski i Dziennik Żołnierza – DPDŻ). The author of this article verifies this journalistic representation, which wasn’t in line with reality. Journalists wrote about such topics as material conditions in the DP camps, possibilities of cultural activities in camps and attitudes of camp authorities towards the DPs. The newspaper criticised the UNRRA which it regarded as a proponent of compulsory repatriation. This and other opinions have been confronted with the actual state of research. Another question raised by the newspaper was one concerning the international efforts taken to solve problem of the displaced persons. DPDŻ’s journalists were against Moscow and its satellites states, which sought to repatriate all the DPs.
Особенности синтаксической организации и пунктуации в рекламном тексте рубежа XIX–XX вв. (на примере региональной прессы)
Authors: Рожкова Полина Алексеевна
Published: October 2021

The article deals with the syntactic organization and punctuation in advertising texts at the turn of the 19th and 20th centuries. The research material were advertising texts and advertisements placed in regional press (“Ural life”, “Irbit fair leaf”, etc.). During the period under review, print advertising is at the stage of formation and has not yet emerged as an independent genre. Modern advertising texts are primarily focused on attracting attention. They should be readable by a potential buyer without any difficulty, therefore, their syntax, punctuation, font and illustrative design should contribute to ease of perception and understanding of the text. In the considered material, the opposite situation is observed. With regard to its genre, advertising at the turn of the 19th and 20th centuries is close to announcements and aims to convey important information. The desire of the seller/manufacturer to tell as much as possible about their product to the buyer results in complexity of the text. Organization of advertising text at the turn of the 19th and 20th centuries involves an active use of abbreviations, complex syntactic constructions as well as unusual design elements (for example, a line break). Syntactic organization of the text at the given period can become an indicator of a gradual transition from the announcement genre to the ad genre: the texts most rich in information, still drifting towards the announcement genre, have complex punctuation and syntactic organization, while texts focused on the emotional response of the reader (a new stage in the development of the ad genre), on the contrary, are distinguished by considerable simplifications.

The text of the drama “Janko krUl’ albAnskaj” by Ilia Zdanevich is the embodiment of the ideas of Russian futurism on the creation of a new poetic language, and reflects discussions on spelling reform relevant to the beginning of the 20th century. Punctuation in the text of avant-garde works plays a special role. By minimal means, using small number of punctuation marks in principle, the author achieves structural division of the text, which contributes to the understanding of its basic constructions – in particular, residual emotions.
«Точки» и «запятые» в структуре ситуации: абсолютный и относительный предел и средства их выражения (аспектуальные характеристики и падеж прямого дополнения)
Authors: Чуйкова Оксана Юрьевна
Published: October 2021

The paper deals with some features of the event structure that influence its formal expression and determine the wider context of a clause. The notion of relative/absolute boundedness is used to indicate the exhaustiveness of the event. The relative boundedness is a feature that makes it possible to use the genitive partitive case as the direct object. Within such perfective verbs as vypit’ ‘drink.PF’ and sjest’ ‘eat.PF’, the nominal case determines the interpretation of a verbal phrase: the accusative indicates the absolute boundedness while use of the genitive results in the relative boundedness. As for degree achievements, delimitative Aktionsart and semelfactive Aktionsart, it is the verb that determines the interpretation of a verbal phrase. What all the examined cases have in common is that the use of the genitive as the direct object marker indicates the relative boundedness (partial resultativeness): the object of the event is a part of the cumulative object of a wider (actual or ideal) situation.

Published: October 2021

The making-do stands out for representing a potential generator of other wastes, such as safety reduction, quality problems, productivity and rework. The paper seeks to analyze the production-related wastes by making-do in order to identify, through the categories of improvisation wastes, the impacts generated by them, from the perspective of the Goiás scenario. At the end of the analysis a matrix was applied for risk analysis of making-do wastes. Data were collected from three construction companies in the city of Goiânia. For data collection, data triangulation was performed through the results of interview analysis, direct non-participant observations, photographic records and document analysis. After data analysis, it is concluded that most improvisations are related to short term planning, logistics and projects. However, the most important impacts of these types of wastes are the need for rework and material waste. As a result, we highlight the importance of studying the wastes related to making-do, as it goes beyond the waste of materials, highlighting issues related to health and safety of the workforce and impacts on the production process as a whole.

Published: October 2021

The Project Management Body of Knowledge (PMBOK®) guide brings together best practices for project management and edited an extension called Construction Extension to the PMBOK® Guide. The medium-term planning level (MTL) is one of the hierarchical levels of the Last Planner System (LPS®) and involves the process of constraint analysis. The present work sought to analyze the contributions of the extension for the construction of the PMBOK® guide for the MTL with the objective of identifying important practices that support the realization of the MTL in the construction. The interactions and contributions of the twelve areas of knowledge of the extension of the PMBOK® guide in the construction with the MTL were pointed out. It was noted that the scope of the MTL permeates and interacts with the management of the twelve areas of knowledge defined by the extension of the PMBOK® Guide in construction. The MTL incorporates actions present in some areas of knowledge or receives input data from others to feed the MTL. The contributions of this paper were to add other categories of constraints to be managed in PMP and to highlight integrated change control and risk management in PMP.

Currently, it is notorious the lack of reliable information that has an inexperienced engineer regarding the process of elaboration of the concrete in situ. Therefore, the main objective of this research was the development of a physical and digital manual to improve the quality of the work carried out in a civil construction project. This paper comprises a study regarding the implementation of a training plan in civil construction work. The training plan covers the tasks associated with the formwork, assembly and elaboration of concrete, which constitutes the main material for the construction industry. The plan has been implemented by means of interviews applied to a person in charge of the project in a construction company in the city of Encarnación, Paraguay. Then, a group of 15 workers have been trained for a period of 3 months with the aim of increase the efficiency and competence, and also, to improve the indicators of productivity and quality of the tasks mentioned above. At the end of the process, the workers have been assessed individually through written tests. The results shown an improvement of competence and productivity of the workers, as well as an increase on the quality of the works.

One of the main protective equipment used to prevent falls is the lifeline. However, at the construction site, this equipment is deficient in visual identification, as there is a lack of information on how to use it properly. The purpose of the study is to create a visual device for guidance on the use of lifeline equipment in construction. As for the research method, a literature review was initially performed. In a second moment, a technical visit was made to a company. The last step consisted of data analysis and the proposition of the device model to orient activities that use lifelines following the model proposed by Valente (2017). The results show the development of a visual device in three parts: a description of the activity to be developed, the protection equipment used and information on how to react in case of an accident at work. The study highlights two contributions: the probable reduction in the number of accidents due to the misuse of lifeline equipment and the validation of the method proposed by Valente (2017) for the design of visual devices.One of the main protective equipment used to prevent falls is the lifeline.

Published: October 2021

This study aims to contribute to an improvement in the management of workers health and safety. Through a bibliographical review the work brings several concepts about safety culture at work, showing that there is still a consensus among the scholars about the subject and showing the importance of understanding the same for organizations success. It sought to analyze the maturity degree of work safety culture in a construction company in Goiânia, through application of a questionnaire based on Hudson’s model. The model is an important managerial tool, because it can define in which of the five stages (pathological, reactive, bureaucratic, proactive and sustainable) the company finds itself, through the way it treats the following factors: information, organizational learning, involvement, communication and commitment. The result of this research demonstrated that both the workers and the administrative team attribute to the organization a transition between the proactive and sustainable stage, but most of it is allocated in the sustainable stage, considered the ideal stage. Safety culture is of paramount importance for improving the well-being of workers towards the work environment, as it contributes to reduction of risks and accidents, requiring a greater investment in this area, either through new studies and research or by the entrepreneurs' awareness.

The manufacturing process of concrete blocks has showed high production costs and high waste generation from their own manufacturing. This paper evaluates the viability of production of recycled concrete blocks using recycled aggregate from manufacturing process industry. This way, the aim of this experimental work was to evaluate the compressive strength, of munufactured concretes blocks using in replacement of natural aggregate the recycled aggregate (20% replacement by mass). The concrete blocks were produced with brazilian Portland cement (CP II F) and meassured for compressive strength in the age of 14 days. The results showed that the shape aggregate and porcentage replacement influenced the durability and compressive strength of the concretes.

A indústria da construção vem passando por uma mudança significativa com o surgimento da indústria 4.0. Entretanto, para obter sucesso e vantagens competitivas, as empresas precisam entender como os processos transformados devem ser gerenciados e medidos. Pesquisadores tem discutido e desenvolvido sistemas de medição de desempenho com foco na indústria 4.0 no ramo industrial, porém existe uma lacuna no contexto da construção 4.0. Assim, o objetivo deste trabalho é identificar indicadores a serem incorporados em Sistemas de Medição de Desempenho (SMD) no setor da construção, visando medir as transformações promovidas pela digitalização no contexto da construção 4.0. Para isso, foi realizada uma Revisão Sistemática da Literatura para identificar os indicadores que estão sendo adotados nos SMDs do setor manufatureiro e com potenciais de incorporação e adequação no contexto da construção civil. Além das medidas tradicionais relacionadas a custo, qualidade e produtividade, foram identificados novos indicadores principalmente no que se refere aos contextos organizacionais, de recursos humanos, e gestão dos sistemas e da tecnologia. A principal contribuição deste trabalho é a indicação inicial de medidas que podem contribuir para o setor da construção melhorar o seu desempenho promovido pela transformação digital.

O processo de planejamento e controle da produção exerce um papel fundamental nas empresas, à medida que o mesmo tem um forte impacto no desempenho da função produção. Diversas técnicas de planejamento e controle de projetos são utilizadas, sendo a Linha de Balanço a mais indicada para projetos com serviços repetitivos, uma vez que utiliza conceitos de fluxo de produção, repetição de ciclos e estabelece a coordenação entre esses fluxos de produção. Dessa forma, esse estudo teve por objetivo uma exploração gráfica sobre os conceitos da Lean Construction e sua ligação com a Linha de Balanço.  Para isso realizou-se um estudo teórico feito através de revisão de literatura sobre o assunto e um levantamento de gráficos que relacionam termos da Lean Construction com essa técnica de programação. Como resultado, obteve-se uma ampla apresentação gráfica sobre os ciclos e os fluxos na construção civil e como os mesmos ocorrem ao longo do tempo, além de verificar a semelhança desses com a Linha de Balanço. Conclui-se por meio destas representações, que os conceitos da Lean Construction e a da Linha de Balanço podem ser trabalhados em conjunto.

Published: October 2021

For local self-government bodies – the level of public authority which is the closest to the people – working with the population is the goal of their activity, therefore, the problem of interaction of local authorities with the population is relevant. The purpose of the study is to review the domestic and foreign experience of interaction of municipal authorities with the population, as well as the development of recommendations of practical importance for improving the organization of local self-government. The author notes a number of problems hindering the development of mechanisms of interaction of local self-government bodies with the population, in particular: lack of understanding by the population of their responsibility in solving problems of municipal education; insufficient access to information about the activities of local authorities; poor use of modern information resources for interaction of local authorities with the population; low level of professionalism of municipal personnel, etc. The study was conducted using the methods of systematic and comparative analysis, comparative legal method. On the basis of the analysis defines the most important mechanisms of interaction of local governments with populations: improving information transparency local authorities; the improvement of existing and development of new normative legal the acts regulating the forms of public participation in solving local issues; the creation of the subjects of the Russian Federation outreach resource for the exchange of experience in implementing practices of interaction of public authorities with the population, etc.

No estudo analisam-se as práticas docentes no ensino da Geografia do 8o ano; no sentido de perceber o modo como um conceito científico é apropriado pela Geografia escolar. A pesquisa foi realizada com professores de Geografia do Ensino Secundário Geral. Para tal, optou-se pelo método fenomenológico. Para a coleta de dados recorreu-se a observação direta e entrevista semiestruturada - grupo focal. Foi pensando no contexto do ensino da Geografia em Moçambique que se trabalhou com a transposição didática do conceito atmosfera do 8o ano. No final do processo, os professores expuseram as suas práticas em sala de aula, o que contribuiu para uma melhor abordagem do conceito atmosfera no ensino da Geografia e ainda, se criaram possibilidades de aprendizagem para os alunos. Do estudo compreendeu-se que ensinar Geografia não é uma tarefa fácil para o professor, como também se pode dizer que não é para o aluno aprendê-la, compreendê-la, e aplicá-la, pois transpor didaticamente os conceitos criados pela ciência sem perder a sua essência é um exercício exigente. Portanto, a transposição didática pode contribuir no processo de ensino/aprendizagem centrado na formação de cidadãos críticos e conscientes da realidade que os rodeia.

FROM SCIENTIFIC TO SCHOOL KNOWLEDGE: the approach of atmosphere in the teaching and learning process of Geography
Abstract
In this study, the teaching practices in the teaching of Geography in grade 8 are analyzed; aiming at perceiving the way a scientific concept is used by school Geography. The research was conducted with Geography teachers from General Secondary Education. Thus, the phenomenological method was chosen. For data collection, direct observation and semi-structured interviews were used - focus group. It was thinking in the context of Geography teaching in Mozambique that the didactic transposition of the concept of 'atmosphere' in grade 8 was focused on. At the end of the process, the teachers exposed their practices in the classroom, which contributed to a better approach to the concept of 'atmosphere' in the teaching of Geography and also, created learning possibilities for students. From this study, it was understood that teaching Geography is not an easy task for the teacher, in the same way it can also be said that it is not an easy task for the student to learn, understand, and apply it, as it transposes didactically the concepts created by science without losing its essence. Therefore, the didactic transposition can contribute to the teaching/learning process centered on the formation of critical citizens and aware of the reality that surrounds them.

THE EFFECTS OF INDIRECT FEEDBACK ON GRAMMATICAL ERRORS IN EFL LEARNER WRITING
Authors: Pham Anh Lan
Published: October 2021

This paper examines the impact of indirect feedback on learners’ grammatical errors in English as a Foreign Language (EFL) writing classes. It also considers students’ attitudes towards indirect feedback. Fifty-six eleventh-grade students and one teacher-researcher participated in this empirical study. Three instruments used to collect both quantitative and qualitative data were pretest, posttest and delayed test on English writing as well as a questionnaire and individual interview on students’ attitudes towards indirect feedback. The results showed that the students in the experimental condition committed many fewer grammatical errors than their counterparts in the control group when errors were treated as a single group. The results also indicated that indirect feedback helped reduce more error categories and more errors in each category, especially those related to the simple past tense. Moreover, the participants in the experimental group had positive attitudes toward indirect feedback. These findings support the claim that indirect feedback may help reduce grammatical errors in student writing.

A Fast Algorithm for Estimating Parameters of a Multivariate Autoregressive Moving Average Processes
Authors: MBAMBE Emilie EPEKA , SOTAZO Angèle YULE , KISETA Jacques SABITI , LIENDI Roger AKUMOSO
Published: October 2021

We propose in this paper a fast and iterative algorithm for estimating the parameters of a Gaussian vector autoregressive-moving average (VARMA) model. This algorithm is a multivariate generalization of that suggested by Sabiti (1996) for estimating the parameters of a univariate ARMA(p,q) process. It is proposed, mainly for providing initial estimators for the iterative maximization of a log-likelihood function. Comparisons about the number of computations in terms of multiplication operations are made with a method that uses gradients to locate a maximum of the likelihood function and the fast method suggested by Spliid (1983).

This is article aims to find out what methods are taken by teacher in teaching children during the Covid Pandemic 19. The method used in the case study is trough interviews, by interviewing R1, R2, R3, R4, R5, and R6. The results show that the learning method taken is DARING ( Method in the Network ) through social media which is widely used whatsapp by sending material through Audio, Visual, and Audio Visual. In particular the assessment taken not only from the values of assignments given by the teacher board, even the assessment of character can also be seen its development. Such as when taking daily tests students are prohibited from cheating both with books and mobile phones. Indirectly the role of parents also helped the council of teachers to assist the course of learning during the covid pandemic 19. In general the role of parents who appear is as a guide, educator, guardian, developer, and supervisor. Cooperation is needed between the two parties so that there are no misunderstanding in distance learning during the covid pandemic 19.
