Relying on the conducted analysis, the author identifies universal and nationally specific means of the animalistic image objectification, describes functions of the zoonym component in paroemias. Scientific originality of the study involves a comprehensive semantic analysis of the Tatar, Russian and English proverbs and sayings with the zoonym component. The research findings are as follows: the author proposes a structural-semantic classification of the Tatar, Russian and English paroemias, identifies their universal and nationally specific features. The researcher for the first time provides a comparative analysis of the Tatar, Russian and English paroemias from the viewpoint of cognitive linguistics, which allows identifying similarities and differences between the Tatar, Russian and English paroemiological worldviews.
Aspects of Semantic Derivation and Development of Polysemy in Synchronic-Diachronic Perspective (by the Example of the German Lexeme Sprache)
Authors: Tsvetaeva Elena Nikolaevna , Maltseva Elizaveta Igorevna
Published: September 2021

The article considers polysemantic nature of the notion “language” when describing art, using the example of the German lexeme Sprache. The purpose of the study is to identify semantic transition mechanisms in formation of the lexeme non-linguistic meanings. The study used the German-language etymological and special-purpose dictionaries, as well as encyclopaedias on the history and theory of art, which made it possible to trace development of the lexeme new meanings. Scientific novelty of the study lies in considering semantic transition as a tool of intersemiotic translation. The attained results have shown that specialised meaning formation of the lexeme Sprache in the metalanguage of art is carried out in two stages and is a transfer between the “language” and “art” systems.

Results of the First Herpetological Survey of Israel’s Mediterranean Coastal Islets
Authors: Slavenko Alex , Maza Erez , Itescu Yuval
Published: September 2021

Small islets in the Mediterranean Sea are often home to reptiles, typically representing an impoverished sample of the continental fauna, yet with high population densities and signs of rapid morphological and behavioral evolution. In this paper, we present the first herpetofaunal survey of several small islet clusters in close proximity to the Mediterranean coast of Israel, only recently geologically separated from the mainland. We performed surveys of five islets during March of 2017 – 2018 and recorded the presence of five different species of reptiles on four of the surveyed islets. Species richness varied between 1 and 4 species, and appeared to be correlated with island area, with a distinct nested structure. Reptile species may have colonized the islets by natural dispersal from nearby coastal populations, or by hitch-hiking on fishing boats and similar methods of human-assisted dispersal. Alternatively, the recorded reptiles may represent relictual populations from earlier geologic periods, when lower sea-levels supported continuous land-bridges between the islets and the mainland. These insular reptile populations require further study to establish the exact means of colonization and describe if and how they differ from mainland populations. We stress the importance of such small Mediterranean islets such as these as centers of unique biodiversity and encourage future study and conservation action aimed at them and similar islets.
La metáfora como mecanismo de inteligencia, creación y comunicación en ciencias duras e ingeniería y su recupero en la docencia universitaria
Authors: Magnasco Humberto Manuel
Published: August 2021

Presentamos una síntesis de nuestra investigación sobre la validez epistémica del recurso a la metáfora en educación superior como mecanismo de inteligencia, creación y comunicación en “ciencias duras” e ingeniería. La misma fraguó en una tesis de maestría en docencia universitaria en la que rastreamos la presencia del mecanismo metafórico en las producciones inaugurales y basales de la ciencia moderna (Galileo, Newton, Faraday, Maxwell, Fourier, Ohm). El método empleado fue cualitativo y de alcance exploratorio, descriptivo y genético, infiriendo desde indicadores empíricos el potencial de inteligencia, creación y comunicación del mecanismo. El diseño fue dialéctico, proponiendo matrices de datos que dieron coherencia y entidad epistémica a los mismos. Detectamos en el avance del conocimiento científico en esta etapa fundamental el uso sine qua non de creativas metáforas, que haciendo pie en los ámbitos “extranjeros” de la vida diaria y de disciplinas ajenas, permitieron inteligir creativamente fenómenos intrigantes y desafiantes. Constatamos que estos últimos, produciendo en el espíritu una especie de “vacío hermenéutico”, desafiaron al investigador y motorizaron un “llenado” creativo inicialmente metafórico (intentando conocer lo desconocido desde lo conocido). Dicha metáfora inicial - cognoscitivamente vívida e implicante- quedó luego disecada bajo un insípido ropaje matemático que la trocó en modelo. Concluimos que, si en la producción del conocimiento científico la metáfora ayudó creativamente a inteligir y matematizar los fenómenos, es oportuna su recuperación por parte de la docencia en orden a promover la construcción de los conocimientos científicos de una manera interesante y significativa. 
Kindergarten in a Large Urban District
Authors: Engel Mimi , Jacob Robin , Claessens Amy , Erickson Anna
Published: August 2021

Using data from 82 classroom observations conducted in a large urban school district, we explore how kindergartners spend their time in general and across schools serving children from lower and higher income households. Consistent with prior research, we find that kindergartners spend the majority of instructional time on reading and mathematics, with little time devoted to other subjects. On average, 2.5 hours are spent on noninstructional activities such as transitions. Kindergartners in lower income schools spend more time on reading and mathematics and experience more noninstructional time. They also spend substantially less time being physically active and have fewer opportunities to choose their own activities than their peers in higher income schools.
Ready for College? Examining the Effectiveness of Targeted Interventions in High School
Authors: Xu Zeyu , Backes Ben , Oliveira Amanda , Goldhaber Dan
Published: August 2021

Kentucky’s Targeted Interventions (TI) program is a statewide intervention intended to prepare non-college-ready high school students for college-level coursework. Using a difference-in-regression discontinuity design, we find that TI reduces the likelihood that students enroll in remedial courses by 8 to 10 percentage points in math. These effects are similar or stronger among students who are eligible for free/reduced-price lunch, students with remediation needs in multiple subjects, and students in lower performing schools. TI also increases the likelihood that students enroll in and pass college math before the end of the first year in 4-year universities by 4 percentage points and by 9 percentage points among free/reduced-price lunch eligible students. However, we do not find evidence of TI affecting credit accumulation or persistence.

Published: September 2021

Purpose of the study. The aim of the study was to study the morphogenesis of granulomatous inflammation in the liver in newborn animals and in remote periods of life.

Materials and methods. The experiment was carried out on 70 newborn C57BL / 6 mice, divided into two groups. On the first day after birth, mice of the 1st (experimental) group were injected intraperitoneally with a solution of the BCG vaccine at a dose of 0.02 mg / kg. On the fi rst day of the beginning of the experiment, the mice of the 2nd (control) group were injected intraperitoneally with 0.02 ml of physiological solution. Liver samples were subjected to morphological and morphometric study: the body weight of mice (g), the volumetric density (Vv) of dystrophy and necrosis of hepatocytes, foci of extramedullary hematopoiesis, the number density (Nai) of binuclear hepatocytes, mitotic figures, the diameter of granulomas (μm), and the number density were calculated (Nai) granulomas in test area.

Results. The introduction of the BCG vaccine to newborn mice on the 1st day led to a delay in their development and a lack of body weight. With the introduction of the BCG vaccine to newborn mice of the C57B1 / 6 line, a delayed formation of granulomas is noted, starting from the 10th day after the administration of the BCG vaccine, and a subsequent increase by 56 days in both the number and size of granulomas. The foci of extramedullary hematopoiesis in the liver of mice after the administration of the BCG vaccine persist for a longer period (up to 28 days), which is probably due to the participation of cells of the foci of hematopoiesis in the inflammatory process in the liver parenchyma. With the introduction of the BCG vaccine, pronounced destructive changes in hepatocytes in mice at all age periods are noted with reduced rates of reparative liver regeneration. Conclusion. The introduction of BCG vaccine to newborn mice led to the formation of tuberculous granulomas in the liver during the adult period of life with the development of destructive changes in hepatocytes and a reduced reparative ability of the liver.

In the literature devoted to the problems of liver transplantation, there is no clearly indicated attitude of the authors to intraoperative epidural blocks, although theoretically the benefits of a sympathetic block are considered. Some sources recommend prophylactic sodium bicarbonate infusion to alleviate post-reperfusion syndrome, but its effectiveness is questionable.

Purpose: to present the physiological, biochemical and hematological characteristics of recipients at the stages of orthotopic liver transplantation with an assessment of the feasibility of using sodium bicarbonate for the prevention of reperfusion complications.

Materials and methods. An observational study, contains an analysis of data from 39 participants operated on in 2020 in the volume of: hepatectomy, an orthotopic liver transplantation, with an initial assessment on the Child- Turcott- Pugh scale of 11 points. All participants were operated on under general inhalation anesthesia with sevoflurane and thoracic epidural three- component anesthesia according to the Breivik- Niemi method. There are 3 stages of data registration: the beginning of the anhepatic stage; the beginning of the neohepatic stage; the end of the operation.

Results and discussion. Significant fluctuations in hemodynamics, violations of the acid-base state and energy metabolism were not revealed; a decrease in hepatic protein synthesis, a shift of the P50 point to the left, and moderate metabolic acidosis did not exceed the levels described in the literature. The dynamics of acidosis, РСО2 and natremia did not depend on the infusion of soda. There was no close correlation between arterial blood pH and lactate concentration.

Conclusion. The benefits and safety of epidural anesthesia in orthotopic liver transplants are obvious and make it possible to recommend this component as a routine element of anesthesia during these operations. The indications for sodium bicarbonate infusion should be narrowed and consensus is needed to determine the critical pH value for sodium bicarbonate infusion.

Differential expression of shisa family member 6 in human epithelial ovarian cancer.
Authors: Mamoor Shahan
Published: August 2021

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published and public microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding shisa family member 6, SHISA6, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. SHISA6 expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. SHISA6 expression correlated with progression-free survival in patients with p53 mutant ovarian cancer. These data indicate that expression of SHISA6 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. SHISA6 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.

Centennial- and orbital-scale erosion beneath the Greenland Ice Sheet
Authors: Balter-Kennedy Allie , Young Nicolás , Briner Jason , Graham Brandon , Schaefer Joerg
Published: September 2021

Erosion beneath glaciers and ice sheets is a fundamental Earth-surface process dictating landscape development, which in turn influences ice-flow dynamics and the climate sensitivity of ice masses. The rate at which subglacial erosion takes place, however, is notoriously difficult to observe because it occurs beneath modern glaciers in a largely inaccessible environment. Here, we present 1) cosmogenic-nuclide measurements from bedrock surfaces with well constrained exposure and burial histories fronting Jakobshavn Isbræ in western Greenland to constrain centennial-scale erosion rates, and 2) a new method combining cosmogenic nuclide measurements in a shallow bedrock core with cosmogenic-nuclide modelling to constrain orbital-scale erosion rates across the same landscape. Twenty-six 10Be measurements in surficial bedrock constrain the erosion rate during historical times to 0.4–0.8 mm yr-1. Seventeen 10Be measurements in a 4-m-long bedrock core corroborate this centennial-scale erosion rate, and reveal that 10Be concentrations below ~2 m depth are greater than what is predicted by an idealized production-rate depth profile. We utilize this excess 10Be at depth to constrain orbital-scale erosion rates at Jakobshavn Isbræ to 0.1–0.3 mm yr-1. The broad similarity between centennial- and orbital-scale erosion rates suggests that subglacial erosion rates have remained relatively uniform throughout the Pleistocene at Jakobshavn Isbræ.
Do toddlers reason about other people’s experiences of objects? A limit to early mental state reasoning
Authors: Woo Brandon Matthew , Spelke Elizabeth
Published: September 2021

Human social life requires an understanding of the mental states of one’s social partners. Two people who look at the same objects often experience them differently, as a twinkling light or a planet, a 6 or a 9, and a random cat or Cleo, their pet. Indeed, a primary purpose of communication is to share distinctive experiences of objects or events. Here, we test whether toddlers (14-15 months) are sensitive to another agent’s distinctive experiences of pictures when determining the goal underlying the agent’s actions in a minimally social context. Across seven experiments (n = 206), toddlers viewed either videotaped or live events in which an actor, whose perspective differed from their own, reached (i) for pictures of human faces that were upright or inverted or (ii) for pictures that depicted a rabbit or a duck at different orientations. Then either the actor or the toddler moved to a new location that aligned their perspectives, and the actor alternately reached to each of the two pictures. By comparing toddlers’ looking to the latter reaches, we tested whether their goal attributions accorded with the actor’s experience of the pictures, with their own experience of the pictures, or with no consistency. In no experiment did toddlers encode the actor’s goal in accord with his experiences of the pictures. In contrast, in a similar experiment that manipulated the visibility of a picture rather than the experience that it elicited, toddlers (n = 32) correctly expected the actor’s action to depend on what was visible and occluded to him, rather than to themselves. In a verbal version of the tasks, older children (n = 35) correctly inferred the actor’s goal in both cases. These findings provide further evidence for a dissociation between two kinds of mental state reasoning: When toddlers view an actor’s object-directed action under minimally social conditions, they take account of the actor’s visual access to the object but not the actor’s distinctive experience of the object.
An open-source color picker for online synesthesia research.
Authors: Root Nicholas
Published: September 2021

Synesthesia is a neurological phenomenon in which healthy individuals experience additional, automatic, and consistent perceptions unrelated to veridical sensory input. For most (but not all) synesthetes, this additional sensation is a color: for example, grapheme-color synesthetes experience colors for letters of the alphabet. Measuring these color associations is of central importance to synesthesia research, but there is no standard color picker “tool” that researchers can adapt to use in their own experiments: each researcher must code their own. This is a barrier to entry for synesthesia research, and additionally creates potential methodological confounds because different researchers make color pickers with different properties. Here, I present SynesthesiaColorPicker, an open-source, mobile-friendly color picker tool that can be integrated with two popular online experiment platforms (Qualtrics and LabJS/ Open Lab) without any prior programming knowledge. The templates, underlying JavaScript code, and detailed instructions are available for download on a GitHub repository. I then use experimental data to show how two methodological design choices in SynesthesiaColorPicker overcome measurable confounds in existing color picker methodology.

Greening lifestyles with good intentions: Cross-country evidence on the association between attitudes and environmentally significant actions
Authors: Petev Ivaylo D. , Coulangeon Philippe
Published: August 2021

Recent evidence shows a considerable potential for individuals to intervene, their widespread willingness to do so but also sizeable barriers they face to reduce their environmental footprint. This study investigates whether pro-environmental attitudes can serve as potent drivers of individual pro-environmental. Using a multi-level latent variable framework, we model the association between attitudes and a diverse range of environmentally significant actions and scale up the analysis to a cross-country setting using the 2017 wave of the Eurobarometer data. We find a moderate, positive association which holds beyond standard sociodemographic and country-level controls and exhibits an additive effect: higher attitudinal levels align with higher numbers of undertaken actions, including difficult, costly and high-impact ones. The attitudes-actions association is contingent on a country's economic affluence and individual socioeconomic status. This, we argue, is evidence of the limits of mitigation strategies which focus exclusively on attitudes-driven behavioral change without consideration for the influence of sociodemographic and country-level inequalities.
Racial/Ethnic Variation in Residential Fathers’ Time in Childcare and Co-presence with Children
Authors: Nomaguchi Kei , Milkie Melissa , Allen Amira , Gustafson Kristen
Published: September 2021

Past research on racial/ethnic minority fathers’ involvement in children’s lives tends to focus on subgroups of fathers and narrow definitions of involvement, making knowledge of racial/ethnic variation in fathering obscure. Using ordinary-least-squared regression models with the 2003-2019 American Time Use Survey (N = 30,622), we compare White, Black, Latino, and Asian residential fathers’ time spent in four childcare activities and 10 additional daily activities when fathers are co-present with children, attending to variation by age of children. Results show that how fathers spend time with children varies by racial/ethnic group across stages of children’s lives. Latino fathers spend more time in presence of young children than other fathers, whereas Black and Asian fathers spend less time in presence of older children than other fathers, with differences concentrated in the amount of downtime spent together. Within father-child co-present time, Black fathers spend more time in religious activities, Latino fathers in shopping, and Asian fathers in hobbies. Considering the narrower arena of childcare, Black and Latino fathers spend less time overall, White fathers spend more time on play, and Black and Asian fathers spend more time teaching children. These findings suggest that broadening assessments of time beyond childcare and being attentive to fathers in different racial/ethnic statuses enrich our understanding of how fathers spend time with children and align more with the whole of family life across children’s developmental stages.

The success of a culture depends on the quantity and quality of water used in fish culture without water exchange, the concentration of aquaculture waste such as ammonia (NH3) will increase very rapidly and is toxic to the cultivated organism. One of the innovations applied in fish farming is integrating plants through an aquaponics system. This study aims to determine the effect of using a settling tub in reducing ammonia waste (NH3) and growth in tilapia aquaculture using an aquaponic tidal system. The size of the initial tilapia seeds used is 3-4 cm. There are two treatments used, without settling tub (A) and addition of settling tub (B) with three replications. However, the results showed no significant differences (P>0.05) between treatments for all parameters observed. It is necessary to carry out further research on different fish and plants to see the optimization in reducing ammonia waste (NH3).
