Prosocial choices: How do young children evaluate considerate and inconsiderate behavior?
Authors: Sierksma Jellie , Klootwijk Christel Leonie Tonia , Lee Nikki
Published: April 2021

Adults often act considerately towards others, for example by leaving the last cookie on a plate or stepping aside on a busy sidewalk. What do young children infer from observing considerate behavior? In three preregistered studies, we assess how young children evaluate considerate and inconsiderate behavior by showing them animated videos in which targets make decisions that either leave or limit choice options for others. Study 1 (N = 372 6-to-12-year-old children, 170 girls, 187 boys (15 not reported), 84.4% native Dutch) showed that older children, but not younger children (i.e., 6 years), evaluated considerate others (i.e., who leave a choice for others) as nicer than inconsiderate others, and they were also more willing to lend their toys to them. Moreover, children’s evaluations were specific to the social domain, as children of all ages evaluated both targets as equally smart. Focusing on younger children (5-7 years), Study 2 (N = 99; 57 boys, 42 girls, 78.8% native Dutch) showed that when the consequences of considerate or inconsiderate behavior were made explicit and videos showed one target at a time, children as young as 5 years old evaluated considerate targets as nicer. Study 3 (N = 43; 20 boys, 23 girls, 92.5% native Dutch) showed that young children also evaluated considerate behavior as nicer when the consequences of considerate behavior were not made explicit. These studies extend developmental research on prosocial behavior and suggest that considerate behavior conveys a clear social signal early in life.

Published: April 2021

This study aims to determine differences in zooxanthella density based on the life forms of coral Acropora Branching, Submassive Acropora, Branching, Foliose, Heliopora and comparing zooxanthella densities between the forms of coral form. This study was conducted in January-February 2020 on Marak Island, Nagari Sungai Pinang, West Sumatera Province. Zooxanthella density was calculated at the Marine Biology Laboratory, Department of Marine Sciences, University of Riau. The survey methode was used in this study, where the data collected was primary data. Coral Sampling was done by free collection using the SCUBA (Self Contained Underwater Breathing Apparatus). The result of study in the waters of Marak Island, West Sumatera on Acropora Branching corals were in the range of 0.004-0.13×106 cells/cm2.  Acropora Submassive range of 2.95- 3.56×106 cells/cm2. Branching  range of 2.41-2.59×106 cells/cm2.  Foliose range of 0.44-1.09×106 cell/cm2. Heliopora range of 1.30-1.59×106 cell/cm2. The highest zooxanthella density was in Submassive Acropora and the lowest in Acropora Branching corals due to different forms of growth and temperature influences. Different forms of coral growth affect the zooxanthella density on a coral and the success of coral growth depends on the zooxanthella density and the size of the corallite of each coral life form.

Apartheid on Display: South Africa Performs for New York
Authors: Kruger Loren
Published: April 2021

In the metropolitan context, South African theater has largely been promoted and received as dramatic testimony to the antiapartheid struggle. Created and performed under particular local conditions and sometimes for quite different occasions and audiences in South Africa, plays such as Woza Albert, Born in the RSA, Asinimali, and Bopha have been marketed and consumed abroad as the authentic and univocal issue of a “blood-filled society staggering towards revolution,” in the words of African-American writer Amiri Baraka (xiii). Baraka’s rhetoric echoes the metropolitan reception for more than a decade of theater performances from South Africa, by which I mean pieces devised and performed by (usually black) South Africans rather than the dramatic literary works of an Athol Fugard. The latter have been absorbed into an international canon of “great works”; the value of the former, however, appears to rest on the performers’ presumed affiliation with a new and integral South African identity and thus on the metropolitan critics’ assumption that such a monological, uncontested identity exists. In the present context of a contradictory sociopolitical dispensation that is hardly postcolonial and in which violent conflict persists over who gets to determine what and who South Africa is, it seems especially important to scrutinize the process of this authoritative representation of South Africa on the metropolitan stage against the plurality of competing sites and shapes of this representation. Neither New York nor South Africa may be as stable as they seem.
Do Journals’ Author Guidelines Tell Us What We Need to Know about Plagiarism?
Authors: Sun Yu-Chih
Published: April 2021

Author guidelines for submitting manuscripts to journals play an essential role in communicating academic ethics and standards to prospective authors and in ensuring the originality of the articles that journals publish. The purpose of this study was to conduct a cross-journal analysis of author guidelines to see how they address plagiarism. One hundred author guidelines were selected randomly and were analyzed qualitatively and quantitatively. The findings revealed that the guidelines varied in the extent to which they covered plagiarism. Among the elements of plagiarism addressed, the four most common were duplicate publication, copyright, the definition of plagiarism of others’ work, and proper citation. The allowance for reproduction of language ranged along a spectrum from very strict (no verbatim copying of another’s words) to less strict (no verbatim copying of significant portions of others’ work). Although self-plagiarism is the most common form of plagiarism, it was addressed relatively less often than plagiarism of others’ work.
CHANGES IN THE CONTENT OF BIOAVAILABLE HEAVY METAL COMPOUNDS IN THE SOILS OF THE CRIMEAN MOUNTAIN PLATEAUS AFTER AFFORESTATION
Authors:   Nikitsky Botanical Gardens – National Scientific Center, Russian Academy of Sciences, Kostenko I.V. , Nikiforov A.R.
Published: April 2021

About 3 thousand hectares of forest stands were created on the surface of the Crimean mountain plateaus in the middle of the 20th century as a result of afforestation. Studies on the influence of these stands on the properties of mountain meadow soils (Phaeozems) showed that under the forest vegetation, the consolidation of structural aggregates, a decrease in the humus content, and an increase in acidity compared to the soils under the meadow vegetation, which could also affect other soil properties, including the mobility of some metals, were observed. The work objective of this research is to conduct a comparative analysis of the content of Pb, Mn, Cu, and Zn compounds available for biota (1 M ammonium acetate) in the soil under mountain meadows, natural beech forest, and artificial forest stands. Following the obtained results, the available Pb, Mn, and Cu compounds accumulated in the afforested mountain meadow soils relative to the adjacent mountain meadows areas. Thus, the average Pb content in the soil layer of 0–10 cm under the mountain pine stands in comparison with the soil under meadow vegetation was 1.6 times higher, Mn – 1.2 times, Cu – 1.2 times. The Pb content was 2.5 times higher, Mn – 1.5 times higher, and Cu – 1.2 times higher under the silver birch stands. The Pb content was 2.2 times higher, Mn – 2.4 times higher, and Cu – 1.5 times higher under Siberian larch stands. The Pb content was 1.9 times higher, Mn – 1.1 times higher, Cu – 1.3 times higher under the sycamore maple stands, compared to the meadow. Differences between afforested and meadow soils in the content of these elements in most cases were significant, except for the Zn content, signs of accumulation of which under artificial stands were not revealed. The Pb, Mn, and Cu content in the brown forest lessive soil (Luvisols) under the oriental beech corresponded to their concentration under the larch, and the Zn content was significantly higher compared to the soil under all species. The main reason for the increase in the mobility of some elements under tree stands is their transition from immobile forms under the influence of increased acidity of afforested soils. Wood litter due to the low content of trace elements in its composition cannot be a source of their accumulation in the topsoil.
IMPACT OF EARTHWORMS OF DIFFERENT MORPHO-ECOLOGICAL GROUPS ON CARBON ACCUMULATION IN FOREST SOILS
Authors:   Center for Forest Ecology and Productivity of the Russian Academy of Sciences, Geraskina A.P.
Published: April 2021

To date, forest ecology has not made any clear conclusions regarding the impact of large saprophagous invertebrates such as earthworms on soil carbon dynamics. Some authors claim that earthworm activities result in decreased carbon accumulation. Other studies show that earthworms contribute to soil carbon accumulation. At the same time, many studies do not take into account the differences between trophic and digging activity of different morpho-ecological groups of earthworms in different soil horizons. The objective of this study was to carry out differentiated assessment of the impact of different morpho-ecological groups of earthworms on carbon accumulation and correspondent soil parameters (nitrogen content and С/N ratio) throughout the change in forest succession status. Field operations were performed in the spring and summer of 2016 and 2018 in three regions: Bryansk Oblast (Bryansk Forest reserve), Moscow Oblast (Moskva–Oka plain, Valuyevsky urban forest) and Northwest Caucasus (Krasnodar Krai, Apsheron forestry; Republic of Adygeya, Caucasian Biosphere Reserve). Three main stages of coniferous-broadleaf forest restoration after clear cuttings were identified in each region. Three test plots 50х50 m were allocated for each stage; geobotanical and soil descriptions as well as earthworm registration were carried out on each plot. It was found out that during the change in forest succession status the species composition and the set of morpho-ecological groups of earthworms became more complicated, but there was no successive replacement of any groups with others. Ambiguous effects of different morpho-ecological groups of earthworms on carbon accumulation in forest soils were revealed. Negative correlation was found between the total biomass of earthworms feeding on the soil surface (epigeic, epi-endogeic and anecic species) and litter store. In the humus horizon, the biomass of epi-endogeic species was positively correlated with the content of carbon. C/N ratio and nitrogen content are unidirectionally correlated with the biomass of earthworms in the horizons of their activity: with an increase in the biomass of earthworms of different morpho-ecological groups, the C/N ratio decreases, and the nitrogen content increases.
Treatment difficulties during COVID 19 pandemic in a patient with giant renal tumor. A small town general hospital perspective
Authors: Attila Szöllösi
Published: April 2021

Introduction: We present an unusual case of papillary renal cell carcinoma, which is a rare subtype of kidney malignancy. Objective: The present case report emphasizes a voluminous left renal tumoral mass causing bowel obstruction and necessity of emergency surgical intervention. Presentation of case: A 74 year old patient with a history of multiple severe cardiovascular conditions, presented in the emergency room accusing abdominal distension and pain, nausea, vomiting and lack of intestinal transit for about 72 hours. Based on the symptomatology, physical examination and imagistic explorations a clinical diagnosis of bowel obstruction was arisen, caused by a voluminous tumor with compression of the large vessels and invasion of the left colon. Given the severity of the cardiovascular comorbidities and the complexity of the case, the possibility of patient’s transfer to a university hospital was arisen, which was not practicable due to the COVID 19 pandemic. During surgical intervention en-bloc resection of the left kidney and tumoral mass was practiced. Histopathologic examination identified the tumoral mass as type I papillary carcinoma of the left kidney. The postoperative evolution was unfavorable, due to the severe cardiovascular comorbidities, on maximal vasoactive support the patient remained hemodynamically unstable, showed progressive myocardial infarction with the persistence of arrhythmias and severely reduced ejection fraction which led to his unfortunate death. Conclusion: Careful patient selection is needed to ensure a favorable risk-benefit ratio. Also a thorough multidisciplinary evaluation of patient and the possible therapeutic options is necessary, in order to create an optimal and individualized treatment plan

Authors: Aashish Kamatham
Published: April 2021

India is the second-most populous country in the world has about 76.6 million people at or over the age of 60, constituting above 7.7% of total population. A cross-sectional study of 300 cases of geriatric and non-geriatric population groups was conducted at well-established Trauma, Orthopaedic and Neurosurgical services centre in Central India. Mechanisms of injury sustained by the participants showed that Falls which include both Ground level falls (GLF) and Fall from height (>2 metres) contributed to 55.4% cases in the geriatric population. The next most common cause of trauma in the geriatric population was road traffic accidents amounting to 34.3% of the cases. Data on the injuries sustained by both the study cohorts in terms of the different body regions based on Abbreviated Injury Scale (AIS) and Injury severity score (ISS) showed the head region was most consistently and maximally injured in both the study populations. Comorbidity profiles of geriatric and non-geriatric trauma populations showed significantly high hypertension, cerebrovascular disease, diabetes, diminished hearing and vision among the geriatric group. The maximum number of geriatric patients underwent Orthopaedic and spine surgeries (44.9%), Intercostal drain placements (34.6%), while the non-geriatric population had a higher number of Craniotomies (40%) and Intercostal drain placement (33.5%) surgeries respectively. The geriatric population had a significantly higher crude mortality rate of 39.3% compared to the non-geriatric population ( 26.3% ). With reference to intervention procedures, the geriatric population had a lower percentage of operative intervention and a higher rate of conservative management as compared to the non-geriatric population.

Pneumatosis coli (PC) is a rare radiological phenomenon of the presence of gas in the wall of the large intestine. It carries a large burden of morbidity and mortality. All patients should have their underlying cause of PC investigated and have targeted therapy. In this novel case, a 68-year-old man developed PC following an aorto-bilateral common iliac artery mycotic aneurysm excision. Fortunately, he was asymptomatic and underwent close surveillance of this condition until near resolution. This case highlights the need for correlation of the patient’s symptoms and clinical features with appropriate aetiology and pathogenesis mechanism of the disease to guide management and optimise health outcomes.

Published: April 2021

The article provides data review of relevant publications, presenting issue of current state of the dairy cattle breeding in Western Europe and Mountain Altai. The intensification of milk production and milk quota abolition weaken milk from mountain farms with regard to direct competition with milk produced on the plains. The consequence is the declining number of mountain farms in the Alps that has negative influence on the ecological and economic situation. There are difficulties in promotion dairy products in the market despite the fact that dairy products are produced in the mountains from grazing cows and have an increased biological value in human nutrition. As a mountain region, Altai Republic has dairy cattle breeding that developed successfully throughout the XX century similar to Swiss concept. However, in recent years the industry is also in crisis due to the low animal productivity and the high costs of fodder production and purchase. The article describes some ways to increase economic efficiency of the industry in the region, considering foreign experience and local specifics.

Treatment of wastewater by adsorption is one of the most environmentally friendly methods, along with high efficiency. The main criteria when choosing materials for wastewater treatment by adsorption are its adsorption properties, porous structure and cost-effectiveness. Heavy metal ions are the main pollutants present in wastewater from machine-building, non-ferrous metallurgy and instrument-making enterprises, its removal being mandatory employing processes such as adsorption. This work deals with the development of materials based on natural clays and on pillared clays and further application in the the adsorption of Ni (II), used as model pollutant, from aqueous solution. The starting natural clay (montmorillonite) was obtained in a deposit of Kazakhstan (Asa), and two additional samples were prepared by treatment of the natural clay with acid and by pillarization with Fe2+ and Zn2+. Batch adsorption experiments were carried out to explore the effect of pH, adsorbent load, contact time and the initial ion concentrations of Ni (II) in the adsorption of the heavy metal from aqueous solution with the three adsorbent samples. A maximum removal of Ni (II) of 98.9% was achieved at pH 10 with a dose of adsorbent of 2 g/L, a contact time of 120 min and an initial concentration of metal ions of 50 mg/L, when considering the Asa natural clay.

The experiments were carried out in a static system in a thermostat glass reactor. It was found that cation exchanger shows high catalytic activity in the studied process - maleic acid conversion was 93%, and maleic hydrazide yield was 90%. The conversion selectivity of maleic acid to maleic hydrazide was 97,8%. The reaction rate was determined from the accumulation of maleic hydrazide. The apparent reaction rate constant (k) was calculated from the second-order reaction rate equation. The effect of initial concentrations of maleic acid and hydrazine hydrate, the temperature on the reaction rate was studied. The first order of maleic acid and hydrazine hydrate is determined. Activation energy of the process found from the Arrhenius dependence is 32,1 kJ/mol. On the basis of kinetic and IR spectroscopic methods, a probable reaction mechanism involving polymer-bound hydrogen ions is proposed.

This scientific article is devoted to the problems associated with the flow of suspensions and emulsions and some simplifications of the real picture of the flow of a polydisperse medium are made. It is also stipulated that differential equations characterizing the motion of suspensions and emulsions should take into account the fundamental discontinuity of the medium and the physicochemical processes of heat and mass transfer occurring in it. Taking into account all these factors, a general equation for multiphase systems is proposed with certain simplifications that do not change. The behavior of particles in two-phase systems, their concentration, collision and coagulation are considered. As a result, it was concluded that there is a multifactorial interaction and mutual influence of both phases in a dispersed flow. A differential equation of motion of a single i-th spherical particle in suspension was proposed, and an equation describing the drag force of a solid spherical particles. Equations of conservation of mass and momentum are presented for one-dimensional laminar motion of two incompressible phases in a gravity field with the same pressure in the phases. Having studied the parameters of the flow of fine particles in a turbulent gas flow, some assumptions were made. It was found that the pulsating motion of particles, performed by them during one period of gas pulsations, can be represented as a change in the pulsating gas velocity in time. The parameter of entrainment of particles by a pulsating medium is an important characteristic in determining the transport coefficients in a turbulent flow. It is concluded that the presence of various kinds of particles in the liquid complicates the problem of solving hydromechanical problems in turbulent and laminar flow, and the assumptions given in the work facilitate the study of this problem.

The article discusses the contributes to the development of a new focus on the use of various mixtures of natural raw materials and waste in the construction materials industry as a strategically important direction for solving the environmental burden and recycling industrial waste with a feasibility study that improves the state of the environment. This problem is particularly relevant in the production of building materials used in environmentally distressed areas of the republic and in conditions of intense corrosion and erosion wear. The production of efficient building materials and products that meet the modern requirements of environmental friendliness, basic physical and mechanical characteristics, availability and cost is an important and not fully solved task in the field of construction and the construction materials industry. Analysis have been conducted on the current state of the local availability of perspective materials for high-quality composite construction materials, their chemical and mineralogical and granulometric properties have been studied, the influence of the granulometric composition of the basic properties of a composite material and features of the structure formation during heat treatment were studies; physical and mechanical properties of the obtained compositions were tested. Optimal compositions and technological schemes for the production of composite materials based on the use of technogenic waste, natural raw materials and their mixtures have been developed to ensure the production of high-quality construction products with specified thermomechanical properties.The optimization of compositions and properties of compositions was carried out using mathematical planning methods, which made it possible to predict changes in the properties of composite materials depending on the number, weight of the components and the size of the filler granules. Experimental batches of at least 3 main types of construction products were obtained.

Published: April 2021

The formation of anti-erosion procedures is based primarily on achieving an equilibrium state that affects the state of the soil or constituent rocks of the slope. In this regard, the formation of a model that can demonstrate the processes of slope destruction, which can be represented not only by soil, but also by rocks or other formations, becomes relevant. In particular, it should be relevant for urban soils and technologically transformed landscapes. The novelty of the study is determined by the fact that all possible materials that form both slopes of natural origin and technological origin are considered as objects of potential erosion activity. The authors of the article are considering the possibility of applying reclamation measures that will reduce the maximum erosion activity within not only natural, but also urban landscapes. The article developed a model for analyzing the potential of erosion activity in combination with the physical parameters of the slopes and their mechanical composition. The practical significance of the study is determined by the fact that the proposed measures and the developed model for countering erosion activity can reduce technological costs for reclamation activities and thus increase the economic and technological efficiency of the project.

The article examines the effectiveness of GIS-technologies in Kazakhstan for determining and clarifying hydrographic characteristics (e.g. catchment area, river length, location, lakes and reservoirs), the analysis of hydrological processes and phenomena, as well as the creation of a cartographic and attributive database of water bodies. Yesil River, the main waterway of the central and northern part of Kazakhstan, is one of the least hydro- logically studied catchments in the region. To address this research and information gap data was obtained from remote sensing and runoff depth based on the Kazhydromet network for the period 1945 to 2016. A topographic and river network map (1:1,000,000) of the Yesil River basin, including locations of gauging stations as well as depth and runoff coefficient maps were created using ArcGIS software. These maps provide a very useful tool for water resource management and economic policy decision making.
YOLO NETWORK TRAINING FOR FACE RECOGNITION IN MEDICAL MASKS
Authors: Temyrkanova E. K. , Saurambekova A.
Published: April 2021

The detection of face masks is a very important issue for the safety and prevention of Covid-19. In the medical field, the mask reduces the potential risk of infection from an infected person, regardless of whether they have symptoms or not. Thus, the detection of masks on the face becomes a very important and complex task. The efficiency of facial recognition systems can significantly deteriorate due to occlusions, such as medical masks, hats, facial hair, and sunglasses. Currently, there are a number of different methods for recognizing objects in an image. One of the most popular methods is convolutional neural networks and their modifications. This article provides a brief description of the YOLO network, an example of training that can detect faces with a mask and without a mask, and the results of the work. The recognition model has been trained on different object recognition pre-trained models with the same data and evaluated on multiple environments to achieve good accuracy for limited identities.

The aim of the present paper is to present algorithms that explicitly construct groups of singular and S-singular elements (modulo squares) in a global function field.
The Historic and Contemporary Permanence of the Doctrine of Discovery in Canada
Authors: Beaulieu Celine Rose
Published: April 2021

In the Truth and Reconciliation’s Final Report, four of the 94 calls to action referred to the repudiation of concepts which have justified claims of European sovereignty while implicitly refuting claims that dismiss the legitimacy of Indigenous land ownership prior to European contact. This paper demonstrates how the concepts of terra nullius and the Doctrine of Discovery have prevented the recognition and affirmation of Indigenous peoples’ sovereignty in Canada historically and presently. This article will first introduce the concepts of the Doctrine of Discovery and terra nullius as religious constructs and demonstrate how these concepts became integrated into the colonial mentality of European countries by drawing from Andrew Crosby and Jeffery Monaghan’s concept of “settler governmentality.” These two concepts, in particular, justified the false pretensions of European countries to assume they could occupy, ‘discover’ and take the land from Indigenous peoples. By acknowledging Indigenous sovereignty is inherently connected to their relationship with the land, this article will conclude by analyzing the work of contemporary academics and reports that argue Indigenous laws cannot be adequately acknowledged under the current Canadian legislation.
Berlin: Bir Büyükşehir Sorunsalının Filme Aktarımı
Authors: PERK Derya
Published: April 2021

19. yüzyılın sonunda Avrupa’da önemli politik ve ekonomik gelişmeler yaşanmış ve bunun sonucunda hayatın günlük akışı da zorunlu olarak değişmiştir. Sanayi Devrimi ile şehirlere göçün başlamasıyla ortaya çıkan mekân değişimi, beraberinde toplumsal yozlaşma, bireysel yalnızlaşma ve memnuniyetsizlik getirmiştir. Bunun sebebi olarak ağır çalışma koşulları, maddi sıkıntılar ve şehir hayatına alışma sürecinde rutin hayatın getirdiği bilindik toplumsal sorunlar gösterilebilir. Modernleşme sürecinin yanı sıra Birinci Dünya Savaşının da yaşanmasıyla var olan sorunlara karamsarlık ve korku da eklenmiştir. Toplum bilincine sirayet eden bu unsurlar, elbette ki çeşitli sanat eserlerine de konu olmuştur. Walther Ruttmann’ın 1927 yılında yönetmenliğini üstlendiği “Berlin. Büyük Bir Kentin Senfonisi” (Orjinali: Berlin. Die Sinfonie der Großstadt) adlı sessiz filmi, Almanya’nın ve Alman halkının 20’li yıllardaki portresini çizmesi açısından önemli bir örnek teşkil etmektedir. Filmde yönetmen, bir yandan büyükşehrin telaşlı ritmini izleyiciye aktarırken, diğer yandan Berlin’i modernliğin simgesi haline getirmiştir. Bunu, Berlin’de günün en erken saatlerinden gecenin en karanlık anlarına kadar çektiği görüntülerle beyaz perdeye aktarmıştır. Siyah beyaz çekilen film, şehrin bir günlük akışını göz önüne serdiğinden tam olarak dönemin bir yansıması niteliğindedir. Bu çalışmanın amacı 20. yüzyılın başındaki Berlin'i incelerken, şehrin yapısının görsel bir medya aracı olan filmde 24 saat içerisinde nasıl ve ne şekilde anlatıldığını ortaya koymaktır.

Biological assets are a unique type of asset, because they undergo growth transformation, and are able to produce an output. This transformation consists of the process of growth, degeneration, production and procreation that can cause a variety of changes qualitatively and quantitatively the life of the asset. This study aims to determine the problem of the reality of obstacles in the application of recording IAS 41 for SMEs fisheries and farming in East Java. Data collection was carried out through the Group Group Discussion (FGD) grouping technique. This data is then processed through three stages, namely: 1) data reduction, 2) data presentation, 3) data analysis and drawing conclusions based on predetermined theories. The results showed that market prices that occurred in Indonesia could not be used as a basis for measuring the value of biological assets in some MSMEs fisheries and farming in East Java. This is because some MSME fisheries and farming actors in East Java are still doing their own estimates in accordance with the conditions of their biological assets. Thus, existing market prices give rise to unreliable information, which allows changes in estimates that differ from time to time according to the life of biological assets.
