Prediction Performance Metrics Considering the Difficulty of Individual Cases
Authors: Kwon Hyunjin , Josephson Colin , Greenberg Matthew , Lee Joon
Published: December 2023

Prediction performance evaluation is an essential step in machine learning model development. Model performance is generally assessed based on the number of correct and incorrect predictions it makes. However, this evaluation metric has a limitation in that it treats all cases equally, regardless of their varying levels of prediction difficulty. In this paper, we propose novel prediction performance metrics considering the prediction difficulty. The novel performance metrics reward models for correct predictions on difficult cases and penalize them for incorrect predictions on easy cases. The prediction difficulty of individual cases is measured using three case difficulty calculation metrics developed by neural networks. We conducted experiments using a variety of datasets and seven machine learning models to compare prediction performance with and without considering the difficulty of individual cases. The experimental results demonstrate that our novel prediction performance metrics enhance the understanding of model performance from various aspects and provide a more detailed explanation of model performance than conventional performance metrics.

Published: December 2023

Background
The effects of air pollution on the results of assisted reproductive technology (ART) treatment in terms of pregnancy outcomes were inconclusive.
Methods
We performed an individual-level retrospective longitudinal cohort study among 11,968 participants undergoing ART treatment from a general hospital in Hefei, China in 2013-20. Monthly mean concentrations of air pollutants [fine particulate matter (PM2.5), suspended particulate matter (PM10), ozone (O3), sulfur dioxide (SO2), Nitrogen dioxide (NO2) and carbon oxide (CO)] during 3 Periods were obtained from ChinaHighAirPollutants (CHAP) dataset: respective Periods 1, 2 and 3 refer to 90 days, one or two years prior to oocyte retrieval. Multiple logistic regression model was applied to explore the impact of air pollution on four ART results (biochemical pregnancy, clinical pregnancy, pregnancy loss, and live birth).
Results
We observed negative relationships of PM10, PM2.5, CO and SO2 exposures with pregnancy outcomes were more evident during one year exposure (Period 2). An interquartile range increment of ambient PM10, PM2.5, CO, and SO2 exposures during Period 2 was associated with respective decrements of 5.85% (aOR: 0.94, 95% CI: 0.90–0.99), 7.82% (aOR: 0.92, 95% CI: 0.88–0.97), 10.60% (aOR: 0.89, 95% CI: 0.82–0.93) and 12.38% (aOR: 0.88, 95% CI: 0.82–0.93) on clinical pregnancy, while O3 and NO2 showed positive associations. Associations were stronger in patients undergoing frozen embryo transfer, aged < 32 years, with normal BMI, employed status, one embryo transferred, and in warm season.
Conclusions
Our data show that long-term individual-level exposure to the air pollutants of PM10, PM2.5, CO, SO2 but not O3 or NO2, especially in one year exposure before oocyte retrieval, could have a negative impact on ART outcomes.

Published: December 2023

With the continuous construction and development of deep engineering, in order to study the macro-damage and micro-change of temperature on sandstone, this paper conducts a series of Uniaxial Compressive Strength (UCS) tests, Acoustic Emission (AE) monitoring and Nuclear Magnetic Resonance (NMR) experiments on white sandstone treated at 25℃, 100℃, 300℃, 500℃ and 700℃. The study shows that the peak stress of the white sandstone specimens decreases with increasing temperature, and the corresponding axial strain increases significantly. The decrease in uniaxial compressive strength and modulus of elasticity increased sharply. The brittle-ductile transition occurs at about occurs between 500°C ~ 700°C. At temperatures between 25°C and 500°C, the peak AE energy occurs near the peak strength of the sandstone. The ringing counts of the sandstone specimens reached a maximum after the peak stress when the temperature was 700°C, and the peak AE energy gradually decreased at higher heating temperatures. The T2 spectrum curve and pore size curve of the white sandstone increased and gradually shifted to the right with the increase of the treatment temperature, and the total area of the T2 spectrum and porosity also gradually increased. There is a negative correlation between porosity and total area of T2 spectrum and peak stress and elastic modulus of white sandstone under high temperature. The micropores showed a monotonically decreasing trend with increasing temperature, the mesopores showed a trend of decreasing, then increasing, and finally decreasing, and the macropores-cracks enlarged the most.

Published: December 2023

In testing industry, precise item categorization is pivotal to align exam questions with the designated content domains outlined in the assessment blueprint. Traditional methods either entail manual classification, which is laborious and error-prone, or utilize machine learning requiring extensive training data, often leading to model underfit or overfit issues. This study unveils a novel approach employing the zero-shot and few-shot Generative Pretrained Transformer (GPT) classifier for hierarchical item categorization, minimizing the necessity for training data, and instead, leveraging human-like language descriptions to define categories. Through a structured python dictionary, the hierarchical nature of examination blueprints is navigated seamlessly, allowing for a tiered classification of items across multiple levels. An initial simulation with artificial data demonstrates the efficacy of this method, achieving an average accuracy of 92.91% measured by the F1 score. This method was further applied to real exam items from the 2022 In-Training Examination (ITE) conducted by the American Board of Family Medicine (ABFM), reclassifying 200 items according to a newly formulated blueprint swiftly in 15 minutes, a task that traditionally could span several days among editors and physicians. This innovative approach not only drastically cuts down classification time but also ensures a consistent, principle-driven categorization, minimizing human biases and discrepancies. The ability to refine classifications by adjusting definitions adds to its robustness and sustainability.
The impacts of inter- and intra-seasonal burns on the terrestrial orchid Pterostylis curta
Authors: Thomsen Alexandria M. , Davies Richard J. P. , Ooi Mark K. J.
Published: December 2023

Prescribed burning is a management tool used for both management of fuel loads and for ecological purposes across fire prone areas. While in temperate areas wildfires usually occur during the hottest summer months, prescribed burns are generally conducted in autumn and spring to reduce risk. Plant species such as orchids are adapted to summer fires and maintain avoidance mechanisms, such as persisting as dormant tubers during the predominant fire season, and therefore may be at risk from prescribed burns occurring during their active life cycle period. Using a glasshouse experiment, we investigated the impacts of fire season on the Australian orchid species Pterostylis curta. This approach allowed us to i) implement seasonal burns and relate impacts to quantifiable life cycle stages of the study species, ii) isolate and assess the role of smoke, and iii) control for life stage of the study species at each of the treatment levels to enable robust comparison. We found that late autumn burns caused complete failure of a cohort in our glasshouse study. Another key finding is that heat alone is not the driver of tuber mortality, because soil heating was similar across all burn seasons, and plants burnt in the three other seasons were able to resprout strongly in the first growing season after fire. Generally, burning orchids like P. curta at the latter stages of their growing season seems to have low risk, while burning at the start of the growing season is of greater risk but potentially with minimal negative impacts.
Spatial delineation of soil erosion vulnerability in Angereb watershed, Amhara Region, Ethiopia
Authors: TESHOME SAMUEL
Published: December 2023

Background: Soil erosion has always been one of the most severe problems challenging watersheds around the world, mostly in Ethiopia. It is the major type of land degradation, resulting from a combination of natural and human activities.
The main purpose of this research is to demarcate a soil erosion-vulnerable area for watershed planning and conservation plans in study area. In order to map erosion hotspot areas multi-criteria decision analysis (MCDA) technique combined with GIS was used. Based on a conversation with local specialists, as well as the topography of the area and the physical and chemical characteristics of the soil types found in the study area, six major factors: and use, soil, slope, rainfall, Topographic Wetness Index (TWI), and Stream Power Index (SPI) were considered. Each factor was reclassified based on sensitivity classes. These reclassified factors overlaid using the ArcGIS 10.7 weighted overlay analysis tool and produce the final soil erosion source area map of study area.
Results: The final findings indicated that 11.18% of the entire watershed area was highly sensitive, 82.93% was moderately sensitive, 4.64% was low, and 1.25% was very susceptible to soil erosion.
Conclusion: Based on these findings, we can conclude that the majority of the investigated region was moderate to high risk, and most of the soil erosion-susceptible areas were found in the northern, eastern, and north-eastern parts of the watershed, which need suitable plans to conserve water and soil to reduce the disturbing issue of soil loss.

Published: December 2023

This paper extracts alginate of Dictyota mertensii (DM), brown macroalgae found on the north coast of northeastern Brazil. A Composite Central Design (CCD) associated with Response Surface Methodology (RSM) was employed to optimize the extraction process of different fractions of alginate, in different conditions of time, temperature, and concentration of Na2CO3. Yield (𝜂), sulfate content, intrinsic viscosity ([𝜂]), viscosimetric molar mass (Mv), color parameters (a*, b* e L*), and M/G ratio are model response variables. The DM algae has its chemical composition expressed. Response surfaces are plotted from the variables studied, quadratic models were predicted, the influence of factors is analyzed, and response variables are subjected to analysis of variance (ANOVA) and F-test at 95% confidence. The antioxidant potential was evaluated based on the scavenging of the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). The maximum extraction yield was 29.28±0.02 %, and sulfate content ranged from 3.50±0,00 % to 12.33±0.29 %. The maximum values of [𝜂] and Mv were 5.84±0.06 dL.g-1 and 278.00±2.66 kDa, respectively. The alginate showed a dark brown color and M/G ratio <1, indicating that the extracted alginate provides rigid and compact gels. The antioxidant potential and the CI50 were 54.93±0.27% and 0.51±0.07 mg.mL-1 , respectively, indicating moderate antioxidant activity.

Published: December 2023

Health outcomes are significantly influenced by unmet social needs. Although screening for unmet social needs has become common in healthcare settings, there is often poor linkage to resources after needs are identified. The structural barriers (e.g., staffing, time, space) to helping address social needs could be overcome by a technology-based solution. This study presents the design and evaluation of a chatbot, DAPHNE©, that screens for social needs and links patients to resources. This study used a two-step approach: (1) iterative design with interdisciplinary stakeholder groups and (2) feasibility and usability assessment. Virtual sessions were held with an interdisciplinary group of stakeholders (n=10) using thematic and content analysis to inform the chatbot's design and development. Evaluation included an online survey, focus group interviews, and scenario-based usability testing with community health workers (family advocates) (n=4) and social workers (n=9). The stakeholders emphasized the importance of provider-technology collaboration, inclusive conversational design, and user education. Users found the chatbot's capabilities met expectations and the chatbot was easy to use (System Usability Scale score=72). The stakeholders raised concerns about accuracy of suggested resources, electronic health record integration, and trust with a chatbot. Future research should examine effectiveness, cost- effectiveness, and scalability of chatbot interventions to address social needs.

Authors: Morozova Elena , Larin Stepan
Published: December 2023

As a relatively new phenomenon in Russia, social entrepreneurship is undergoing the scientific understanding and the formation of a conceptual apparatus. The purpose of the study is to substantiate the author’s vision of the social entrepreneurship essence and its representation in definitions. The meaning of social entrepreneurship determines the expediency of its understanding in a broad and narrow interpretation. In a narrow intepretation, it is proposed to define it as the entrepreneurial activity of medium-sized and small businesses aimed at achieving socially useful goals, contributing to solving social problems of citizens and society. In a broad sense, social entrepreneurship includes what its narrow meaning implies, as well as socially oriented activities of commercial enterprises; social activities of non-profit organizations, charitable foundations; informal social entrepreneurship, including patronage. In this case, social entrepreneurship is an organizational and economic activity aimed at solving social problems of society or its individual categories based on the entrepreneurial approach.

Published: December 2023

Combining with the characteristics of Fe3O4 and activated carbon, magnetic granular activated carbon (GAC–Fe3O4) was prepared by chemical coprecipitation. With GAC–Fe3O4 as the adsorbent, the effects of GAC–Fe3O4 dosage, the initial pH of wastewater temperature, and the initial concentration of copper (II) and chromium (Ⅵ) on the removal performance were explored. The adsorption process of copper (II) and chromium (VI) on magnetic GAC was studied using adsorption kinetics, adsorption isotherms, scanning electron microscopy, and infrared spectroscopy. The experimental results indicate that among these influencing factors, the pH value of wastewater plays a vital role in the removal efficiency. When the pH value was 6 and 2, the initial concentration of copper (II) and chromium (VI) ions was 5 ppm, the optimum removal efficiencies of copper (II) and chromium (VI) were 99.98 and 96.39%, respectively. As to the adsorption mechanism of GAC–Fe3O4, the adsorption of copper (II) and chromium (VI) in wastewater was more consistent with the Langmuir model. The adsorption process in this study can be well explained by the pseudo-second-order kinetic model.
Analysis of a simplified approach for the determination of modified Kostiakov model parameters
Authors: Zakwan Mohammad
Published: December 2023

Accurate estimation of infiltration losses is very important in many hydrologic projects. However, the lack of available data often forces hydrologists to resort to the application of empirical and semi-empirical models for estimating the infiltration rates. Estimation of infiltration rate from these empirical and semi-empirical models is highly dependent on the method adopted to determine the parameters of models. One of the most common infiltration models known as the Kostiakov model was modified to rectify zero infiltration at the start of the infiltration process. Recently, a simplified approach for determining the parameters of the modified Kostiakov model was proposed. The present article focuses on analyzing the reliability of the simplified approach for determining the parameters of the modified Kostiakov model. In this regard, six observed datasets were analyzed from different parts of the world to arrive at some generalized results on the reliability of the simplified approach. Cumulative infiltration obtained from simplified approaches was compared with that obtained through the application of an excel spreadsheet-based nonlinear optimization solver. It was found that on average Sum of Square of Error reduced by 72% on application of nonlinear optimization as compared to the simplified approach.

Changing from orbital flights to exploration of remote space will require development of an automated onboard system of monitoring, optimization and predicting cosmonauts' physical performance. The paper proposes a method of predicting the physiological cost of work using the data about daily training with the help of machine learning methods. Mathematical models were constructed for 3 cosmonauts assigned for 6-month missions. Prediction was made using the linear regression, decision trees and random wood. Model quality was assessed and retraining confirmed using R2 (proportion of the explained dispersion). The highest value of metrics R2 = 0.61 was calculated for the random wood. Distance covered in the treadmill passive mode was found to make the largest contribution to the predicted value.

Chromatography-mass spectrometry was used to investigate dynamics of volatile organic compounds released by 6 coal plastics of a carbon fiber and epoxy binder proposed for internal structures of manned spacecrafts. It was established that temperature growth higher than 90 °С increases migration and enlarges the spectrum of volatile organics, hygienically important aldehydes primarily, which is characteristic of autocatalytic radical depolymerization with production of volatile low-molecular-weight compounds. Kinetics of their off-gassing can be used to characterize destruction of the epoxy base of composite materials (CMs). Primary products of the thermo-oxidative destruction of these CMs are aldehydes and ketones; at 150 °С and 180 °С, concentrations of these compounds reached maximum levels and made up 98 % of off-gassed compounds.

Childhood Heart Tumors: Detection, Diagnosis, and Treatments
Authors: Jayaraman Megala , Sivakumar Diveyaa
Published: December 2023

:

Childhood cardiac tumors are rare but challenging conditions that can have a significant
impact on a child’s health and even be fatal if not detected and diagnosed timely. While various types
of tumors can occur in the heart, the most common among children are benign tumors, such as
rhabdomyomas. Diagnosis of pediatric cardiac tumors is often challenging and requires a
combination of clinical examination, imaging studies and biopsy. In some cases, the tumors may be
asymptomatic and discovered incidentally, while in others, they can cause symptoms, such as
shortness of breath, chest pain, arrhythmias and congestive heart failure. Treatment options for
pediatric cardiac tumors vary depending on the type, size and location of the tumor and may include
surgical resection, watchful waiting or a combination of both. The prognosis for children with cardiac
tumors is generally good, with a high rate of complete cure in many cases. However, long-term
follow-up and monitoring are important to detect and manage any potential complications or
recurrence of the tumors.

Authors: Yarahmadi Zahra , Sadeghi Atefeh , Mohammadian Fahimeh , Roustaei Farzad , Hajizadeh Mohammadreza , Mirzaei Mohamamdreza , Swann Jennifer , Hosseiniara Reza , Mahmoodi Mehdi
Published: December 2023

Background:

Various forms of epigenetic modification, including DNA methylation,
contribute to hepatocellular carcinoma (HCC) dissemination, invasion, and metastasis. The Persian
shallot (Allium hirtifolium Bioss.) is reported to have antibacterial, antifungal, antioxidant, and anticarcinogenic
properties.

Aims:

In the present study, we examined the expression of DNA (cytosine-5)-methyltransferase 1
(DNMT1) and ten-eleven translocation methylcytosine dioxygenase 1 (TET1) at the mRNA level in
HepG2 cells following treatment with Persian shallot extract.

Method:

Ethanolic extracts of Persian shallot were prepared and dried at 80°C and 50°C for 20 and
30 minutes, respectively. Different concentrations of dried shallot extract over the range of 0-250
µg/ml were prepared. HepG2 cells were cultured and the cytotoxicity of each extract concentration
was measured using an MTT assay. The gene expression in treated and untreated cells was assessed
by Real-time polymerase chain reaction (RT-PCR).

Results:

The half maximal inhibitory concentration (IC50) was determined to be 149 µg/ml using an
MTT assay. A concentration of 175 µg/ml was found to reduce the expression of DNMT1 in the
treated group compared to the control group (P<0.001). Furthermore, the TET1 mRNA of HepG2
cells was down-regulated significantly after treatment with 100 and 1000 µg/ml of Persian shallot
extract (P<0.05). These doses reduced the viability of the samples by 60% or higher.

Conclusion:

This study provides evidence for the potential use of Persian shallot extract as a supplementary
herbal agent for the treatment of HCC. The concentrations of extract used in this study
are near or above the level required for toxicity, and as such, further study is warranted.

Authors: Rey Juniman , Widiyanto Slamet , Retnoaji Bambang
Published: December 2023

The current high demand for Yellow rasbora (Rasbora lateristriata) is not supported by the availability of captured Yellow rasbora in nature. Aquaculture is the most rational way of utilizing biological natural resources. In intensive aquaculture, it is necessary to optimize all processes that occur in aquaculture, including hatchery. However, the common problem that often happens in hatchery activities is spawning which depends on the season. The hormonal manipulation technique is an appropriate way to stimulate gonadal maturation. Oodev is a hormonal combination of pregnant mare serum gonadotropin and anti-dopamine to stimulate gonadal maturation. The purpose of this study was to determine the effectiveness of using the Oodev with different doses in feed to accelerate gonad maturation of female Yellow rasbora. The study was carried out with four treatments and three replications in 21 days with different doses of Oodev, such as; A (Feed without Oodev), B (0.5 mL/kg feed), C (1 mL/kg feed) and D (2 mL/kg feed). The parameters observed in this study were gonad maturity level, histological structure of ovary, gonadosomatic index, fecundity, and diameter of eggs. The results showed that the dose of Oodev at 1.0 mL/kg feed was an effective dose to optimize the gonad maturity of female Yellow rasbora. This is proven by the highest results shown on all parameters, such as; the maturity level in the IV phase, histological structure of the ovary which showed the dominance of the oocyte maturation phase, gonadosomatic index of 14.014%, the fecundity of 721 eggs, and egg diameter of 0.865 mm. In conclusion, using Oodev in feed at a dose of 1.0 ml/kg of feed for 21 days is an effective dose to optimize the maturation of female Yellow rasbora.

Published: December 2023

The induction of colchicine mutations is one method of breeding. PT Gunung Madu Plantations, for example, has induced mutations of commercial sugarcane (Saccharum officinarum L.) varieties, however, investigations on the impact of colchicine on stomatal characters have received less attention. Therefore, this study aimed to analyse the stomata character of 21 sugarcane mutants of the GMP3 variety at PT Gunung Madu Plantations, Lampung, Indonesia with a focused look at stomata aperture width, stomata length and width, number of stomata, stomatal density, and stomata index. The collected data were analysed using cluster and Principal Component Analysis (PCA) through MVSP software. This study showed that all GMP3 mutants had Graminae-type stomata. In terms of stomata length and width, the average size of the GMP3 variety mutant was greater than that of the control. The diversity of stomata characters is fairly high due to differences in stomata size between GMP3 and control mutants. With a similarity index of 0.20, the phenetic analysis of 21 mutants of the GMP3 variety revealed that the relationship between mutants and controls was getting further. A six-character principal component analysis revealed that axis I's total variation accounted for 40.54 percent of the variation and had an eigenvalue of 2.43, whereas axis II's contribution to the variation was 19.02 percent and had an eigenvalue of 1.14. The findings indicate that stomata are excellent taxonomic evidence for identifying and analysing sugarcane varieties induced by colchicine-induced breeding.

Published: December 2023

Abstract: People are pressured for time in today's fast-paced environment, and technology assists them in a variety of ways. Agriculture is the primary industry in India. As a result, in the current environment, increasing output or production is critical. When it comes to determining certain chemical features of soil that have an immediate impact on plant growth, traditional farming faces various obstacles. Another critical factor to consider is the effect of timely water supply on plant output. The soil alkalinity and electrical conductivity are measured with PH electrodes. This study also looked into the real-time detection of soil variables and the location of chemical properties like pH, humidity, temperature, and soil moisture using a Raspberry Pi as a controller. Semi-supervised learning will be carried out in a methodical manner using the Q-learning algorithm. We used a range of samples in the experiment to show how to apply the indicated performance.

El objetivo del presente estudio fue evaluar la asociación entre el perfeccionismo, en sus dimensiones adaptativas y desadaptativas, y los esquemas desadaptativos tempranos (EDT) propuestos por Young (1999), en una población de adultos jóvenes universitarios estudiantes de Psicología (N=307). Además se examinó el rol predictivo de los EDT y dominios de esquemas sobre las dimensiones del perfeccionismo. Los instrumentos utilizados fueron: la Almost Perfect Scale-Revised (APS-R, Slaney et al., 2001; adaptado por Arana, Keegan, & Rutsztein, 2009) y el Schema Questionnaire-Short Form (SQ-SF, Young & Brown, 1994). Los resultados de las correlaciones mostraron que la escala Discrepancia del APS-R (representativa del aspecto disfuncional del perfeccionismo) se asocia significativamente con todos los EDT y todos los dominios de esquemas propuestos por Young. Las subescalas diseñadas para evaluar el perfeccionismo adaptativo, también presentan asociaciones significativas con creencias disfuncionales, aunque en mucho menor grado, siendo incluso en algunos casos la relación inversa. Los análisis de regresión múltiple dan cuenta que varios dominios de esquemas y EDT son predictores significativos del perfeccionismo desadaptativo, mientras que para el perfeccionismo adaptativo el único dominio que se mantuvo como predictor significativo fue el de Sobrevigilancia e Inhibición y el esquema Estándares Inflexibles.

Introduction: The neonatal intensive care unit (NICU) is the place intended for the treatment of newborns, premature or full-term, who need specialized assistance due to clinical conditions. Objective: To identify the role of nurses in neonatal care during hospitalization in the NICU. Methodology: Scoping review based on the assumptions of the Joanna Briggs Institute review method. The guiding question was: "What scientific evidence shows the care practices for newborns in the Neonatal Intensive Care Unit? Searches were conducted in five national and international databases, on papers published until December 2022. Of the 5,803 studies found, 302 were selected for reading in full, resulting in a final sample of 08 studies analyzed. Results: The 08 publications analyzed were published from 2018 to 2023 nationally and internationally. Based on the title and abstract, 80 studies were evaluated and 18 studies followed by eligibility for full-text reading step. As for the type of study they were clinical trials, systematic review and scientific articles. This procedure was chosen for allowing the synthesis and analysis of the scientific knowledge already produced on nursing care in intensive care units for premature infants, highlighting some procedures that the health team should undertake, specifically on the care of premature infants in their recovery, due to their fragility and need for individualized care, since their hospitalization period will last months and the process is slow, therefore the importance of the recovery of this newborn extends to the family, where we will have even more success in reducing mortality. Conclusion: The nurse has a crucial role in caring for the newborn during hospitalization in the NICU, being able to approach and assist in building the maternal-infant bond. For this, good care practices are needed during birth, encouraging the approximation between mother and NB immediately after delivery, in skin-to-skin contact (kangaroo method).

The objective of this study was to investigate how families who lost a family member as a result of COVID-19 have structured themselves in the resilient process of mourning. This is a qualitative research, which used the Episodic Interview technique as a research instrument. Five family members of patients who died from COVID-19 participated in the study, invited by recommendation from the Social Assistance Reference Center and Basic Family Health Units in the municipality; with the study approved by CEP/FPM, under opinion number 5,977,311. Among the reports from the sample of interviewees, it was unanimous among those interviewed that religion was an element that could serve as a source of emotional support in the face of loss. It was observed that all these losses occurred in public hospitals in the city of Patos de Minas, and psychotropic medications were used as a result of grief. Finally, limitations of the study included reluctance to participate due to the painful nature of the subject and a lack of understanding about the academic research process, as the initially proposed sample was larger than those who actually participated in the research. In view of this study, new reflective research is suggested on the elaboration of grief in pandemic consequences and methods for professional psychologists to clinically help bereaved patients.

Recoding, Reaccentuation, Creative Association (Topos of the Incomplete Discoveries of Precursors in the Works of Russian Modernists)

The article focuses on cultural transfer — i. e. the process of “reformatting,” which ideas, texts and authors inevitably undergo while getting into a foreign context. Based on the analysis of Russian modernist literature, which intensively assimilated the ideas of Western literature, the article shows how major cultural phenomena became a “productive basis” both for literary achievements of equal merit and for “popular,” imitative ones. The paper draws particular attention to the fact that even early writings of some of Western European authors gained more popularity in Russia than in their home countries. However, due to the intensity of literary and social life in Russia in the second half of the 19th and early 20th centuries, the readers’ receptivity to literary novelties also enhanced. Russian modernists turned to their European “teachers” in order to resolve new issues, but at the same time they reinterpreted them. The formation of Russian modernist aesthetics went hand in hand with a revision of aesthetic and ideological principles of European authors, and discussions about the ways of further development of Russian literature and the role, which the “transplantation” of the latest achievements of Western culture played in it, generated the basis for the first manifestations of the Russian version of modernist aesthetics.
