Published: January 2022

A lot of research has been conducted to examine the effect of gender differences on language learning motivation in various learning environment, yet the outcomes remain contradictory. This study investigates gender differences in 568 Indonesian senior high school students’ motivation to learn English online during the COVID-19 pandemic. In this quantitative enquiry, the data were collected using a motivational questionnaire containing a number of items indicating motivational components. One-way MANOVA was performed to examine not only the students’ overall motivation, but also the effect of gender differences on three motivational variables, namely instrumental orientation, self-efficacy beliefs, and self-regulation. The findings revealed that the students’ overall motivation differs by gender. Furthermore, it was indicated that, in general, female students possessed higher levels of motivation than male students in learning English online. The results support the growing stereotype claiming that female learners tend to outperform their male peers in language learning. The analyses on the motivational variables indicated that female students had higher level of instrumental orientation and they were more self-regulated compared to male students. In terms of their self-efficacy beliefs, no significant differences detected between male and female students in learning English online during the COVID-19 pandemic.

Conflitos em formação
Authors: Kant de Lima Roberto , Heitor Pedro
Published: January 2022

Este texto identifica e discute as moralidades e os conflitos decorrentes da formação de profissionais das carreiras de segurança pública no Curso de Tecnólogo em Segurança Pública e Social na modalidade de ensino a distância da Universidade Federal Fluminense. O argumento é construído a partir da experiência etnográfica dos autores na criação e coordenação do curso e na administração dos conflitos de ordem acadêmica surgidos no decorrer de seu desenvolvimento. As observações foram realizadas nos primeiros anos do curso, de 2013 a 2018. A reflexão sugere que o estranhamento dos alunos com a Universidade demonstra as descontinuidades da convivência civil-militar, mas também permite compreender as demandas de um tratamento igualitário por parte dos agentes de segurança pública institucionalmente inculcados de uma hierarquia excludente. Assim, não basta socializar os alunos nas regras republicanas e democráticas para que eles assumam a postura pedagógica de reproduzi-las no tratamento aos cidadãos que demandam seus serviços, mas é necessário que esses esforços sejam acompanhados de transformações na estrutura profunda das instituições de segurança pública.

The appeal to the study of plate complexes of the Jewish Autonomous region is due to a number of circumstances. The main ones are: the small number of registered Neolithic settlements in the region, the lack of complete data on the middle Neolithic cultures of the region (which creates a kind of information vacuum between the cultures of the Middle and Lower Amur), the obscurity of connections and vectors of cultural influences of ancient communities, and others. The proposed article is devoted to a preliminary analysis of the ceramic material of the new complex of the Bijan-4 monument of the middle Neolithic period, the nature of the stone industry of which is focused on the preparation of subprismatic micronuclei, their splitting and obtaining knife-shaped blanks. The pottery of the settlement has bright individual features, on the one hand, which have no direct analogues in the famous monuments of archeology of the South of the Far East, and at the same time reveals cultural indicators that indicate a connection.

Introduction. Cystic lung diseases are rare (orphan) diseases. Lung cysts are an important X-ray and morphological sign that contributes to the correct diagnosis. The aim of the researchwas to describe histologic features and computed tomography findings in patients with pulmonary Langerhans cell histiocytosis (PLCH), lymphangioleiomyomatosis (LAM), primary malignant lung tumors, and endometriosis of the lung. Materials and methods. We evaluated video-assisted surgical lung biopsies from 139 patients, with 86 patients having LAM, 47 having PLCH, and in threes having primary peripheral lung adenocarcinoma and endometriosis of the lung. The average age of patients with LAM was 41±10 years, LCG – 32±11 years, lung adenocarcinoma – 62±3.5 years, and endometriosis of the lung – 32±4.1 years. All patients had undergone high-resolution computed tomography of the lungs (HRCT) before the biopsy was obtained. We performed histological and immunohistochemical examinations of lung tissue specimens. Antibodies to CD1a, SMA, HMB-45, CD207 (langerin), CD10, receptors to progesterone, and estrogen were used in the study. Results. We described HRCT, histological, and immunohistochemical features of cystic lung diseases, including characteristics of the walls of cystic cavities in patients with PLCH, LAM, primary malignant lung tumors, and endometriosis of the lung. Conclusion. The variety of causes of lung cysts required a differential diagnosis, considering the patients’ ages, HRCT data indicating the localization of the pathological process, histology, and immunohistochemistry if necessary.

Introduction. Choroidal melanoma is a malignant neoplasm of the eye’s vascular membrane. Prognosing and preventing metastasis are the main objectives of ocular oncology, aimed at maximizing the relapse-free survival of patients. Our goal was to determine the features of the cellular and stromal microenvironment of metastatic choroidal melanoma based on the immunohistochemical characteristics of surgical specimens. Materials and methods. We conducted a retrospective analysis of surgical specimens of cases of choroidal melanoma obtained from 2013 to 2017 and divided them into 2 study groups: group 1 included cases of choroidal melanoma without distant metastases (n=25) and group 2 involved cases of choroidal melanoma with distant liver metastases (n=18). The study was conducted using medical records analysis, histological, immunohistochemical, morphometric, and statistical research methods. Results. In group 2, the level of cells expressing CD4 markers – 138.5 (99.8;153.3), CD68 – 137 (99,5;173,8) and CD56 [5 (3;6)] prevailed significantly. The indicators of CD4 lymphocytes >95 and CD68 macro-phages >104 were found to allow the prediction of the appearance of distant choroidal melanoma metastases with the sensitivity of 83.3% and 72.2% and specificity of 76% and 76%, respectively. The indicators of the volume density of blood vessels in the tumor <3.9 (with a sensitivity of 77.8% and specificity of 64%) were of the same prognostic value. Conclusion. Metastatic choroidal melanoma is characterized by features of the cellular and stromal microen-vironment. Quantitative indicators of CD4 lymphocytes and CD68-macrophages and the volume density of blood vessels in the tumor have prognostic value with high sensitivity and specificity for predicting distant tumor metastasis. Keywords: choroidal melanoma, lymphocytes, macrophages, metastases, tumor blood vessels

In this study, a seismic reflection dataset and well-log data were integrated to investigate the geometry and internal configuration of a turbidite channel system within the Late Cretaceous interval of the deep-water Kribi-Campo sub-basin, offshore Cameroon. This interval is characterized by a well-developed submarine channel system consisting of an early and a late-stage channel. Morphologically, the submarine channel system has a northeast-southwest trend and is U-shaped in cross-section with a length of 56 km within the study area. The early-stage channel has a relatively straight morphology and varies in width and depth from 3 to 5 km and 89 to 197 m, respectively. However, the late stage of the channel is characterized by a narrower (1 to 3 km) and shallower (41 to 103 m) incision, with sinuous morphology carved into the early channel infill. The changing interaction of differential tectonic subsidence, relative sea level, source sediment supply and slope gradient change are considered to be the major control on the geometry and internal characteristics of the submarine channel system. Sag subsidence during the Campanian led to basin deepening and the widespread development of basinal sediments as submarine fans and promotion of submarine channel system development. The filling of the channel system occurred during a long-term Maastrichtian relative sea level rise, punctuated by falls in relative sea level. Sand appears to have been fed to the channel system by the palaeo-Sanaga and palaeo-Nyong Rivers, with sand rich aprons developed were these rivers debouched into the study area. The early stage of the submarine channel is dominated by coarse-grained sediments in the southwest and fine-grained sediments in the northeast, while the late-stage channel is mainly filled with fine-grained sediments. The presence of coarse-grained sediments occur within the submarine channel axis downstream represents a potential for hydrocarbon reservoirs with enhanced petrophysical qualities due to a low depositional gradient. The geomorphological analysis of this ancient submarine channel system along the western African margin, as presented in this study, has broad implications in the understanding of the distribution of deep-water sediments with potential for hydrocarbon exploration in the region.
Powering Earth’s ancient dynamo with silicon precipitation
Authors: Wilson Alfred , Pozzo Monica , Alfè Dario , Walker Andrew , Greenwood Sam , Pommier Anne , Davies Chris
Published: January 2022

Earth's core has produced a global magnetic field for the last 4 Gyrs, presently sustained by inner core growth.Models of the core with high thermal conductivity suggest potentially insufficient power available for the geodynamo prior to inner core formation ~1 Ga.Precipitation of SiO2 from the liquid core might offer an alternative power source for the magnetic field before inner core growth, however, no estimates of partition coefficient exist for conditions of the early core.We present the first determination of the silicon partition coefficient at core-mantle boundary conditions and use these results to build a thermodynamic model that is integrated into a model of coupled core-mantle thermal evolution.We show that models including precipitation of silicon can satisfy constraints of inner core size, mantle convective heat flux, mantle temperature and a persistent ancient geodynamo whilst those excluding fail.Successful power from precipitation favours an oxygen poor initial core composition.
Urinalysis: Extract the Relevant Information Before Throwing it into the Drain
Authors: Lamsal Madhab
Published: January 2022

From ancient time urine has been considered as a substance of importance and examination for physical wellbeing. Evidences from the ancient civilizations including the Egyptian, Sumerian, Babylonian and Eastern Civilizations such as Vedic cultures support the use of urine as an index of physical and mental well-being. Classified as coloured, black, frothy, cloudy and sweet, urine used to be correlated with different disease conditions such as jaundice, kidney diseases, diabetes etc. These practices have been carried on even by the alchemists and have now formed as an integral constituent of clinical laboratory diagnostics.
Modern approach to urinalysis can be credited to Dr. Richard Bright, MD, who in 1827 by performing urine examinations related to vol-ume, colour, pH, protein (but not cast) corre-lated his findings to several diseases and clini-cal picture including edema, proteinuria etc.
Urinalysis combines the expertise from vari-ous disciplines including biochemistry, pa-thology, microbiology, cytology etc. Urinalysis may be used for screening, diagnosis, monitoring and prognosis due to the ease of collection in any settings. Modern day tech-niques such as molecular biology, immunolo-gy, and mass spectrometry with high resolu-tion microscopy have taken up urinalysis to explore the genetic predisposition to inherited diseases and tumor studies besides the routine diagnostics. So, variation occurs in urinalysis from the simple routine analysis, microscopic examination to highly sophisticated and ad-vanced automated analytical techniques. Uri-nalysis therefore, forms a key component of personalized medicine also integrating with proteomics, genomics, metabolomics approaches.

The controlled use of antimicrobials is important for national and international policymakers to draw guidelines on its use. Assessing AMR in meat-producing industry is essential to track emerging resistant pathogens that are common between animals and humans. In this study, we have aimed to investigate the prevalence of bacteria in meat products and the antimicrobial resistance pattern in those isolates.
Methods: This study is a quantitative, observational study, where we collected meat samples (n=118) from shops, in Banepa and Dhulikhel Municipality. The samples were cultured in appropriate media for isolation of bacteria. Subsequently, AMR pattern was studied through antibiotic susceptibility test using Kirby Bauer Disc Diffusion method.
Results: In our study, only two sites, out of 48, did not have any pathogenic bacteria. There were total of 113 iso-lates from 118 samples. E. coli (62.8%), Enterococcus (14.1%), Klebsiella pneumoniae (11.5%), were the most prevalent bacteria in processed samples including MRSA (4%). Additionally, 81.6% of the isolated E. coli were resistant to Ampicillin and 60.5% to Ciprofloxacin and 35% to Gentamycin. 43.6% of all isolated E. coli, 100% of all Klebsiella, 100% of all Enterobacter and 25% of all Citrobacter were multi-drug resistant. The resistance was mostly observed against Ampicillin (83.3%), followed by resistance against Ciprofloxacin (64.4%), Gentamycin (58.8%), Ceftazidime (38.8%), with the lowest resistance against Sulbactam/Cefoperazone (3.3%).
Conclusion: E. coli was the most prevalent organism in meat samples. Multi-drug resistance was also most common in E. coli with resistance against Ampicillin, Ciprofloxacin and Gentamycin. Therefore, we recommend for more controlled use of antibiotics in animal rearing industry and more hygienic environment at meat vendors.

Agriculture is the science and art of cultivation of the soil, rearing of livestock and raising of crops. Agricultural sector is considered as the most essential tool for the common masses to get their livelihood. It is estimated that about two-third of population is still dependent on agriculture in India. Throughout the world near about 50 % persons are associated with agricultural activities and their production. Soils which are rich in mineral contents and adequate climatic conditions are the factors which are vital for agricultural activity. The contribution of agriculture at national level on Gross Domestic Product is dynamic in nature and has reduced from 30% in 1990-91 to about 14% in 2011-12, it then again increased and reached 17% in 2019-20 up to about 19.9% in 2020-21 but still it is considered as the backbone of Indian economy. Agriculture sector should be given priority in order to make adequate measures to reduce poverty and to provide food security to the common people. The growth of agriculture is vital for inclusive and sustainable development of the nation. The growth of agriculture in India, is facing the challenges of unemployment, rural poverty, underemployment and accessibility of natural resources. The aim of this paper is to highlight whether the Government Policies and Programmes related to agriculture has done well in improving the living standard of people. This paper will focus on whether the people of district Shopian got benefited from agricultural schemes implemented by the ministry of agriculture.

giovane poesia nella Svizzera italiana
Authors: Valentini Jordi
Published: January 2022

The article provides a broad overview of the poetry produced in Italian-speaking Switzerland over the past twenty years. The first part presents three channels of poetry dissemination (journals, editorial projects, and literary festivals) both within and outside the Swiss-Italian territory. The second part reflects on some critical readings of Swiss-Italian poetry and addresses the reasons why some forms of poetic writing have appeared later or to a lesser degree within the Swiss territory than they have in Italy, despite the two countries’ proximity. From this analysis, it is argued that the lack of strong counter styles in Swiss-Italian poetry has hindered the development of more mature and diverse forms of poetic expression. In the conclusion, it is argued that the non-use of digital resources for poetry production and dissemination in Italian-speaking Switzerland, as well as an often short-sighted cultural policy, are other important points to address in order to promote dialogue within and beyond the Swiss-Italian border.
 
L’articolo fornisce una panoramica ampia della poesia prodotta nella Svizzera italiana negli ultimi vent’anni. La prima parte indaga tre principali canali di diffusione (riviste, case editrici, festival letterari) dentro e fuori il territorio della Svizzera italiana. La seconda parte riflette su alcune letture critiche della poesia nella Svizzera italiana e cerca di stabilire le ragioni per cui alcuni tipi di scrittura poetica siano giunti tardi o poco sul territorio svizzero rispetto all’Italia, nonostante la vicinanza tra i due paesi. Da questa analisi, si argomenta che la mancanza di controtendenze forti nella poesia nella Svizzera italiana abbia impedito lo svilupparsi di forme di espressione poetica più mature e diverse. In conclusione, si ritiene che il mancato uso di strumenti digitali per la produzione e la disseminazione della poesia nella Svizzera italiana, oltre che una politica culturale spesso poco lungimirante, siano temi importanti da affrontare per promuovere dialogo dentro e oltre il confine della Svizzera italiana.

Distribution of Household Labor Between Mothers and Fathers in Rural and Urban Malaysia
Authors: Hossain Ziarat , Madon Zainal
Published: January 2022

This study examined whether the distribution of household labor including childcare in Malay families varied as a function of the gender of parents and their rural-urban residence. Using a convenience-sampling approach, we interviewed mothers and fathers from 50 rural and 50 urban intact Malay families in peninsular Malaysia. We employed the tenets of the bioecological systems theory to interpret the findings. Multivariate analysis of variance revealed that mothers spent more time doing housework, laundry, childcare, and preparing meals than fathers did and fathers spent more time in maintenance and shopping for food than mothers did in both rural and urban families. Whereas urban fathers spent more time in childcare and shopping for food than their rural counterparts did, mothers and fathers in urban families equally participated in keeping track of expenses. The discrepancy between mothers’ and fathers’ time engagement in childcare was less in urban families than it was in rural families. Mothers were more engaged in traditional areas of household labor than fathers and compared to rural fathers, urban fathers spent more time in most household tasks including childcare. In view of rapid urbanization and multiethnic social context, the current findings are important because they highlight the contemporary patterns of parental engagement in household labor including childcare in understudied Malay families.
Construction of Childcare Practices Among Icelandic and Polish Parents Living in Iceland: Mixed-Methods Explorations
Authors: Arnalds Ásdís A. , Björk Eydal Guðný , Dís Skaptadóttir Unnur
Published: January 2022

The parental leave policy in Iceland is designed to encourage both parents to work and care and access to public early education and care (ECEC) for under six-year-olds is widespread. To date, research has not focused on how migrants in Iceland arrange care for their young children. Poles constitute the largest group of first-generation migrants in Iceland, and the study addresses the question of how they arrange care for their children compared to Icelandic parents. A population-based survey and qualitative interviews with parents were used to gain an understanding of the childcare practices of the two groups of parents during the first two years after childbirth. In the study, childcare practices refer to the use of paid parental leave and care arrangements after the leave period is over. The study draws on Bourdieu’s concept of habitus when discussing how parents construct their childcare practices. The findings show that although Polish and Icelandic parents use their entitlements to paid parental leave to a similar degree, their childcare practices are quite different. While there is more emphasis on family care among Polish parents, Icelandic parents rely more on public out-of-home care options, showcasing how parents construct childcare practices in a constant flux of values and the social context in which they live.
PREVENTION OF STUDENTS’ MISTAKES DURING THE STUDY OF FRACTIONAL RATIONAL EXPRESSIONS IN THE NEW UKRAINIAN SCHOOL
Authors: Blahodyr Liudmyla
Published: January 2022

Among the semantic lines of the school course in algebra, the line of expressions and their transformations is essentially significant. Free execution of the main types of transformations of whole and fractional, rational and irrational expressions is a prerequisite for further successful mastering of other semantic lines. Therefore, the provision of strong knowledge and skills on identical transformations of expressions should be the subject of constant attention of the mathematics teacher.The article considers typical mistakes of students during the study of the semantic line of expression and transformation of expressions, the course of algebra in institutions that provide basic secondary education, namely in the process of studying the topic “Fractional rational expressions”. The analysis of the most widespread mathematical errors of schoolchildren, psychological and pedagogical preconditions of their occurrence is carried out. The method of organization of preventive activity of the teacher of mathematics is offered (under preventive activity of the teacher of mathematics we understand the activity initiated by necessity: to prevent mathematical mistakes of pupils, to correct the admitted, having found out the reasons of their occurrence), and transformations of whole expressions.Preventive activities should be organized as a process of interaction between teachers and students, during which through specially selected methods, firstly, reveals the origin of errors, and secondly, organizes work to prevent and correct them. The main task of the formation of preventive activities of students is to develop their ability to independently adhere to all its structural components. The result of such activities largely depends on how the teacher understands the structure of mental activity of students in specific learning conditions, is able to take into account the objective patterns of learning material, psychological and pedagogical patterns of perception and memory.The effectiveness of the proposed method was tested by the author in the research process: “Methodical system of analysis and prevention of mathematical errors in the study of algebra in primary school”.
