IMPLEMENTATION OF NATIONAL HERITAGE IN PIANO MUSIC BY MODERN CHINESE COMPOSERS
Authors:   Herzen State Pedagogical University of Russia, Saint Petersburg, Russian Federation, Yan Rong
Published: December 2021

The purpose of the study is to identify and scientifically substantiate the extent to which traditional national culture has influenced the creation of modern Chinese piano music. Exploring the principles of modern Chinese composers' work with folklore, the author reveals the main trends in Chinese piano music at the present time. The scientific novelty lies in the consideration of various ways of integrating traditional Chinese musical culture into the piano works of the XXth – XXIst centuries. It was found that Chinese composers show a strong orientation towards the national tradition. The main idea of developing this trend is to turn to the roots as well as the cultural origins. This enables contemporary authors to successfully combine traditional musical means with innovative creative pursuits. The works of Li Yinghai, San Tong, He Lutin, Zhao Xiaosheng and Zhu Wanhua showed that the manifestations of national colour in piano works are as diverse as entire Chinese culture. The study also established a profound relationship between the figurative, genre and compositional uniqueness of the piano music of Chinese composers with the national cultural heritage.
DRAMATIC EXPRESSIVENESS OF THE LANGUAGE OF FOLK CHARACTER DANCE IN CLASSICAL HERITAGE BALLETS
Authors:   Bolshoi Ballet Academy, Moscow, Russian Federation, Pashkova T. V.
Published: December 2021

The article focuses on the phenomenon of folk character dance, which is a unique feature of Russian art, traces the key stages in the development of folk character dance in Russian ballet and identifies the sources that served as the basis for its figurative language. It is noted that the language of folk character dance is the creative fruit of many choreographers, whose works in the XXIst century are perceived as vivid examples of heritage. The author reviews the specificity of imagery in folk character dance currently existing in classical ballet repertoire. Significant attention is paid to the subtleties of depicting national characters when creating dance images of various ethnic groups. The author also considers the characteristic visualization in folk character dance, highlighting and describing distinctive features of a number of national characters more frequently implemented by the language of folk character dance in classical ballet and opera choreography of Russian music theatres. The article substantiates the idea that underestimating the potential of the language of folk character dance as means of expressiveness in ballet theatre leads to limitations for the new generation of choreographers striving to create realistic and truthful dramatic characters, depriving them of national distinction. In her research, the author aims to actualize the question of preservation of national character on the Russian ballet stage in the XXIst century.
A study on the modeling for obesity
Authors:   ,   University of Winnipeg Library, Lim Sung Young
Published: December 2021

This study primarily aims to develop an Agent Based Model (ABM) that can simulate the obesity rates based on statistical analysis and to find out how obesity is affected by risk factors in a Canadian environment. As obesity can have many causes, it is assumed that various risk factors, not just a decisive one, have an influence on obesity and they interact with one another. Therefore, unlike most previous studies, I approached the obesity problem as a Complex -Adaptive System (CAS). The data used for this study was provided by Statistics Canada, and the Canadian Community Health Survey (CCHS). This survey is a cross-sectional survey that collects self-reported information related to health status, health care utilization, and health determinants for the Canadian population. To build the Obesity ABM, it is necessary to find out which risk factors are closely associated with obesity and to what extent they interact with one another. Twelve categories of factors that are expected to influence the obesity rate were chosen on the basis of the related works. Through the statistical data analysis carried out, the main factors and variables for obesity were identified and their respective mathematical relationships obtained. From this, two categories that have several sub-factors for the obesity model were chosen. I implemented statistical data analysis on the CCHS dataset to see the interrelationship among the factors. Also, I implemented a year-to-year analysis that can show how people change their obesity status each year. Based on the data analysis result, I defined rules for how each risk factor changes each year. These rules are applied to the obesity model using NetLogo. The architecture of obesity model implementation consists of three main parts: The population module, the risk factor module, and the results module. Performance evaluation was conducted to examine whether the obesity model can simulate the obesity rate. For this evaluation, the data of CCHS from 2009 to 2014 and the result of the obesity model which is generated by simulation are compared. Model calibration was executed to fit the actual data to the model test result. The result of the model test shows that the percentage error is less than 5%. This means that the obesity model has high validity in predicting obesity for each risk factor. The obesity ABM is a useful tool to find out the risk factors related to obesity and their relationships in the Canadian population. Thus, this model can potentially assist to improve obesity management at various levels. At the individual level, everyone can find what kinds of strategies are best fit to improve her/his physical condition. Also, at a government or community level, it could help develop policies for people to continue to implement these strategies well. This will lead to reducing the associated social costs and help to promote national health.
Smaller Extended Formulations for Spanning Tree Polytopes in Minor-closed Classes and Beyond
Authors: Aprile Manuel , Fiorini Samuel , Huynh Tony , Joret Gwenaël , Wood David R.
Published: December 2021

Let $G$ be a connected $n$-vertex graph in a proper minor-closed class $\mathcal G$. We prove that the extension complexity of the spanning tree polytope of $G$ is $O(n^{3/2})$. This improves on the $O(n^2)$ bounds following from the work of Wong (1980) and Martin (1991). It also extends a result of Fiorini, Huynh, Joret, and Pashkovich (2017), who obtained a $O(n^{3/2})$ bound for graphs embedded in a fixed surface. Our proof works more generally for all graph classes admitting strongly sublinear balanced separators: We prove that for every constant $\beta$ with $0<\beta<1$, if $\mathcal G$ is a graph class closed under induced subgraphs such that all $n$-vertex graphs in $\mathcal G$ have balanced separators of size $O(n^\beta)$, then the extension complexity of the spanning tree polytope of every connected $n$-vertex graph in $\mathcal{G}$ is $O(n^{1+\beta})$. We in fact give two proofs of this result, one is a direct construction of the extended formulation, the other is via communication protocols. Using the latter approach we also give a short proof of the $O(n)$ bound for planar graphs due to Williams (2002).

Insecticidal potency of mixtures of plant powders and Actellic SuperTM (Pirimiphos-methyl + Permethrin) on Callosobruchus chinensis F. and Sitophilus zeamais Motch
Authors: Bett Philip K , Kiplagat Ann J. , Deng Arop L.
Published: December 2021

Insect pests still cause substantial quantitative and qualitative grain loss ranging from 20 to 100% in small holder farming systems in tropical countries. Synthetic pesticides are recommended as stop gap measures for the management of stored product insect pests. However, their application has not been fully exploited in small scale farming due to environmental, health, and economic concerns. As a result, new researches have shifted focus to exploiting pesticidal plants as alternatives to synthetic pesticides. Therefore, the current study evaluated mixtures of plant powders and reduced amount of Actellic superTM (pirimiphos-methyl + permethrin) as alternative insecticide formulation against Callosobruchus chinensis and Sitophilus zeamais. Green grams and wheat grains were mixed with a mixture of plant powders in the ratios of 1:1, 1:3 and 1:9 to obtain four rates (0.0, 2.0, 6.0 and 10%w/w). Grains and plant powders were also mixed with reduced amount (10, 25, and 50 %) of recommended rate of Actellic SuperTM to obtain dosages as above. Twenty unsexed adults, 1-5 day old S. zeamais and C. chinensis were introduced into treated grains. The mixture of C. lusitanica: T. vogelii powders in the ratios of 1:1, 1:3 and 1:9 caused mortality in C. chinensis of 55, 95 and 85%, respectively. At the same ratio, E. saligna: L. camara mixture produced mortality in S. zeamais of 77, 82, and 85% respectively. In mixture of C. lusitanica and T. vogelii and reduced amount of Actellic SuperTM by 50% the mortality of C. chinensis was 85 and 80 % respectively. Similarly, E. saligna and L. camara and reduced amount of Actellic SuperTM by 50% caused a mortality of S. zeamais of 48 and 97% respectively. The application of plant powders and reduced amounts of synthetic insecticide has the potential to be applied in stored product pest control
Seroprevalence and risk factors of Neospora caninum and Bovine Viral Diarrhoea Virus in smallholder dairy cattle in Kenya

Published: December 2021

Little is known of the risk factors associated with occurrence of Neospora caninum and Bovine Viral Diarrhoea Virus (BVDV) infection in Kenya. This cross-sectional study hypothesized that there are significant biosecurity measures associated with N. caninum and BVDV infections on smallholder dairy farms in Kenya that could be adopted to reduce seroprevalence and impacts. From 158 randomly selected farms in Meru County, Kenya, 470 serum samples were collected from dairy cattle (over six months of age and unvaccinated for these two pathogens). Sera were analyzed for antibodies to N. caninum and antibodies and antigens to BVDV. Data on risk factors were obtained through face-to-face interviews with the farmers. Multivariable logistic regression models were used to identify significant risk factors associated with seropositivity for the pathogens. The apparent seroprevalence of N. caninum, BVDV antibody, BVDV antigen, and co-infection with N. caninum and BVDV antibody and/or antigen were 35.1%, 47.1%, 36.2% and 18.5%, respectively. Risk factors associated with N. caninum antibody included: introducing milking cows into the farm, lending of cattle between farms, farm dogs having access to bovine aborted fetuses, and dogs whelping in the farm compound, with an interaction between the last two variables. BVDV antigen was associated with cattle having contact with pigs, and an interaction between cattle age and whether farms introduced new calves onto farms, and cattle age and whether visiting dairy farmers have access to the cow shed. Cows had higher odds of having BVDV antibodies compared to heifers. Factors associated with co-infection included cow parity, direct contact between dairy cattle, dogs and goats, and introducing new milking cows into the farms. Antibody and antigen results may be partly a function of classical swine fever virus or border disease virus interactions. Farmer education on these biosecurity measures is recommended, along with introduction of BVDV vaccination.

Katsauksessa kuvataan tärkeimpiä tuloksia Välitä viljelijästä -projektin toimenpiteistä, joita ovat alueellisten työntekijöiden tarjoama ammatillinen apu sekä ostopalvelusitoumuksilla hankittu asiantuntija-apu. Katsauksessa kuvataan erityisesti toimenpiteiden työkykyvaikutuksia. Tulokset koskevat projektin toimia vuosilta 2017–2018.

Tulosten mukaan Välitä viljelijästä -projektin toimenpiteet ovat hyödyttäneet kyselyyn vastanneita maatalousyrittäjiä. Vastanneista maatalousyrittäjistä 87 prosenttia oli tyytyväisiä ostopalvelusitoumuksella hankittuun asiantuntija-apuun ja kolme neljästä koki alueellisen työntekijän avun riittäväksi. Taustamuuttujista nousi tilastollisesti merkitseväksi vain ikä. Lisäksi asiantuntija-avusta oli vastaajien arvioimana hyötyä sekä psykososiaaliseen kuormitukseen että koettuun työkykyyn.

Jälkeenpäin kysyttynä koettu työkyky oli parantunut ostopalvelusitoumuksella hankitun asiantuntija-avun myötä selvästi. Ennen asiantuntija-apua vastaajat antoivat työkyvylleen arvioksi 4,9, asiantuntija-avun jälkeen 6,9 asteikolla 0–10. Vastaajista 45 prosenttia koki työkykynsä parantuneen asiantuntija-avun myötä. Työkyvyn parantumista selittivät sosiaalisen hyödyn mittari (se, oliko kokenut saaneensa asiantuntija-avusta hyötyä omaan jaksamiseen sekä sosiaalisiin suhteisiin), ammatillisen hyödyn mittari (se, oliko kokenut saaneensa asiantuntija-avusta hyötyä tilan talouteen, johtamiseen ja työtyytyväisyyteen) sekä riittävän avun saanti alueelliselta työntekijältä. Tulokset tukivat tutkimuksessa käytettyä integroitua työkykykäsitystä.

Published: December 2021

The purpose of the article is to introduce into scientific circulation little-known and controversial objects made of stones discovered during our field surveys in 2019 on the Tersk Coast of the White Sea near the Khlebnaya River. The monument consists of 27 boulder structures of four types: ring-shaped layouts with a recess in the center –– boulder pits (24), “seid”, “pile”, a flat boulder with stones laid on it. Boulder pits within the borders of the Russian Federation are found in the coastal zone of the Western and Northern White Sea regions and the Barents Sea. The distribution of such objects is noted in Finnmark and Finnish Lapland and correlates with the area of historical settlement of local Sami groups. We tend to interpret the “boulder pits” as objects associated with non-Christian cult practices, possibly of a funerary nature.
The problem of perception of the scanned paper sheet image as an authentic image of the object
Authors:   Barents Centre of the Humanities of the Kola Science Centre of RAS, Travin I. A.
Published: December 2021

The article considers the issue of the researcher's perception of the scanned image of paper sheets: both separate and as part of a book. The importance and timeliness of work on obtaining digital copies of books and sheets with text / photographs was emphasized. The problem is the authenticity of their depiction of a physical object. The methods of scanning and visual features of the image on an electronic screen are characterized, depending on whether the work is carried out to scan a paper sheet in its entirety or minus the margins and edges of the sheet. Currently, there are no technologies for transferring the texture of a paper sheet when scanning, which leads to an erroneous solution to this problem by increasing the clarity of scanning. The greatest authenticity of the image of a physical object can be achieved by scanning the entire sheet, without deliberately separating the margins and edges of the sheet.

La aplicación de intereses en el proceso laboral
Authors: Consuelo Ferreyra
Published: December 2021

En un contexto de economía inestable e inflacionaria, el debate acerca de la actualización judicial de créditos provenientes de indemnizaciones recobra especial trascendencia y enciende nuevamente el alcance entre la tesis nominalista y valorista y la aún vigente prohibición de actualización monetaria o repotenciación de deudas cualquier sea su causa.

Si bien el debate no es nuevo, si no por el contrario, el tema de la actualización monetaria mediante la aplicación de intereses ha sido objeto de innumerables discusiones doctrinarias y jurisprudenciales. Se pretende hacer un repaso para analizar su aplicación judicial actual en el ámbito laboral.

El tema en cuestión merece análisis sobre los siguientes puntos a saber: el encuadramiento de las indemnizaciones principalmente como obligaciones de dar sumas de dinero, la determinación de la deuda, su necesidad de actualización y los intereses como vía indirecta de reajuste.

A partir de dicha revisión conceptual es que se analiza cuál ha sido la tasa judicial aplicable por los tribunales, cuestionamiento que deriva la necesidad de analizar el origen de la facultad judicial para determinar intereses y su consiguiente potestad para declarar la inconstitucionalidad de las leyes.

Research as an Outsider: Positionality, Ethics, and Risk
Authors: Maley William
Published: December 2021

Outsiders—or “foreigners”—who study violent extremism in affected countries can have multiple iden- tities as students of violent extremism, as students of the countries in question, and as “foreigners” to the contexts they study. They often have long-standing personal relationships with local community members and in some cases they have spent more time living in the countries they study than in their countries of nationality. Yet they inhabit an ambiguous space, being “insiders” in the eyes of some, and “outsiders” in the eyes of others. This ambiguity gives rise to both practical and ethical challenges in undertaking fieldwork. The following reflections draw on the author’s own experiences to illustrate some of the complexities associated with positionality, ethics, and risk as well as important considerations that all researchers should take into account when undertaking fieldwork in a country other than their own.

In monopropellant system, hydrogen peroxide is used with catalyst to create an exothermic reaction. Catalyst made of silver among the popular choice for this application. Since the catalyst used is in porous state, the effect of its porosity in the hydrogen peroxide monopropellant thruster performances is yet unknown. The porosity changes depending on factors including catalyst pact compaction pressure, bed dimension, and type of catalyst used. As researches on this topic is relatively small, the optimum porosity value is usually left out. The performance of the thruster indicated by the pressure drop across the catalyst bed. Porosity of the catalyst bed adds additional momentum sink to the momentum equation that contributes to the pressure gradient which lead to pressure loss inside thruster. The effect of porosity influences the performance and precision of the thruster. Study of the pressure drop by the catalyst bed requires a lengthy period and expensive experiments, however, numerical simulation by mean of Computational Fluid Dynamics (CFD) can be an alternative. In this paper, 90 wt% hydrogen peroxide solution with silver catalyst is studied in order to investigate the influence of porosity to the performances of the thruster, and to find the optimum porosity of the thruster. Species transport model is applied in the single-phase reaction simulation using the EDM for turbulence-chemistry interaction. Through this study, the effect of porosity towards the thruster performances represented in term of pressure drop, exit velocity, bed temperature, and thrust, and porosity of 0.4 found to be as an optimal value.

Aim: According to World Health Organization data, around 1.5 billion people in the world use tobacco products. Nicotine, the most common use of tobacco, is the main psychoactive substance that causes addiction. Exposure to nicotine during pregnancy increases the risk of low placenta weight, stillbirth, congenital heart disease, musculoskeletal defect. Antioxidants are used to protect against teratogenic substances such as nicotine. The purpose of the study was to determine the skeletal system malformations caused by low (3 mg/kg) and high (6 mg/kg) doses of nicotine during embryonic bone evolution by using the double skeletal staining method and the protector role of vitamin E in preventing these malformations.Material and Method: The rats were divided into 6 groups: the control, low-dose nicotine, high-dose nicotine, low-dose nicotine+vitamin E, high-dose nicotine+vitamin E and vitamin E. The development of the skeletal system of the fetuses was examined by the skeleton staining method. The anterior and posterior extremity images of the fetuses were examined under the stereomicroscope and then through photographing total bone length, ossification length and ossification rate were calculated in the ImageJ program. Results: There was an important decline in the total bone length, ossification length and ossification rate (p<0.05) in the bone measurements of the front and hind extremities, while it was found that the treatment groups approached the control group and the increases were important (p<0.05). Conclusion: It was concluded that being to nicotine during pregnancy delayed skeletal ossification and that vitamin E, which is an antioxidant, may be protective opposite the teratogenic effect of nicotine on the bone.
CAF: el banco de la reactivación de América Latina y el Caribe

CAF, como Banco de Desarrollo de América Latina y el Caribe, tiene por misión ayudar a los países a enfrentar retos estructurales que afectan su capacidad de desarrollo relacionados con la productividad, las brechas sociales y, más recientemente, el reto del cambio climático y la sostenibilidad ambiental. Estos se han exacerbado con la irrupción de la pandemia del COVID-19 amenazando con retrotraer las ganancias que se habían logrado en algunos indicadores sociales en los últimos 10 años. El riesgo también atañe a consecuencias de largo plazo sobre la productividad de las economías por daños en la asignación de recursos y aumentos en la informalidad, y sus consecuencias sobre las habilidades de los trabajadores actuales. A ello se debe sumar el deterioro de las capacidades de los futuros trabajadores por la interrupción de los procesos educativos. El propósito de esta nota es elaborar un diagnóstico de estos desafíos estructurales que enfrenta la región y cómo estos han sido potenciados por la crisis sanitaria. También discutir el marco de políticas que podría ser relevante para apoyar la recuperación, y cómo la acción de CAF y su proyección futura puede ser un instrumento eficaz para acompañar a los países con servicios financieros, apoyo técnico y de conocimiento con el objetivo de implementar esta agenda y apuntalar el desarrollo inclusivo y ambientalmente sostenible.

We report the detection of more than 120 emission lines corresponding to eight complex organic molecules (COMs; CH3OH, CH3CH2OH, CH3OCH3, CH3OCHO, CH3COCH3, NH2CHO, CH2DCN, and CH3CH2CN) and three isotopologues (CH2DOH, 13CH3CN, and CH3C15N) toward the western component of the Ser-emb 11 binary young stellar object using observations with the Atacama Large Millimeter/submillimeter Array at ∼1 mm. The complex organic emission was unresolved with a ∼0.″5 beam (∼220 au) in a compact region around the central protostar, and a population diagram analysis revealed excitation temperatures above 100 K for all COMs, indicating the presence of a hot corino. The estimated column densities were in the range of 1017−1018 cm−2 for the O-bearing COMs, and three orders of magnitude lower for the N-bearing species. We also report the detection of H2CO and CH3OH emission in a nearby millimeter source that had not been previously cataloged. Ser-emb 11 is classified in the literature as a Class I source near the Class 0/I cutoff. The estimated COM relative abundances in Ser-emb 11 W and the other three Class I hot corino sources reported in the literature are consistent with those of Class 0 hot corinos, suggesting a continuity in the chemical composition of hot corinos during protostellar evolution.

Low-density points (LDPs), obtained by removing high-density regions of observed galaxies, can trace the large-scale structures (LSSs) of the universe. In particular, it offers an intriguing opportunity to detect weak gravitational lensing from low-density regions. In this work, we investigate the tomographic cross-correlation between Planck cosmic microwave background (CMB) lensing maps and LDP-traced LSSs, where LDPs are constructed from the DR8 data release of the DESI legacy imaging survey, with about 106–107 galaxies. We find that, due to the large sky coverage (20,000 deg2) and large redshift depth (z ≤ 1.2), a significant detection (10σ–30σ) of the CMB lensing–LDP cross-correlation in all six redshift bins can be achieved, with a total significance of ∼53σ over ℓ ≤ 1024. Moreover, the measurements are in good agreement with a theoretical template constructed from our numerical simulation in the WMAP 9 yr ΛCDM cosmology. A scaling factor for the lensing amplitude A
lens is constrained to A
lens = 1 ± 0.12 for z < 0.2, A
lens = 1.07 ± 0.07 for 0.2 < z < 0.4, and A
lens = 1.07 ± 0.05 for 0.4 < z < 0.6, with the r-band absolute magnitude cut of −21.5 for LDP selection. A variety of tests have been performed to check the detection reliability against variations in LDP samples and galaxy magnitude cuts, masks, CMB lensing maps, multipole ℓ cuts, sky regions, and photo-z bias. We also perform a cross-correlation measurement between CMB lensing and galaxy number density, which is consistent with the CMB lensing–LDP cross-correlation. This work therefore further convincingly demonstrates that LDP is a competitive tracer of LSS.

Magnetic field line reconnection is a universal plasma process responsible for the conversion of magnetic field energy to plasma heating and charged particle acceleration. Solar flares and Earth's magnetospheric substorms are two of the most investigated dynamical systems where global magnetic field reconfiguration is accompanied by energization of plasma populations. Such a reconfiguration includes formation of a long-living current system connecting the primary energy release region and cold dense conductive plasma of the photosphere/ionosphere. In both flares and substorms the evolution of this current system correlates with the formation and dynamics of energetic particle fluxes (although energy ranges can be different for these systems). Our study is focused on the similarity between flares and substorms. Using a wide range of data sets available for flare and substorm investigations, we qualitatively compare the dynamics of currents and energetic particle fluxes for one flare and one substorm. We show that there is a clear correlation between energetic particle precipitations (associated with energy release due to magnetic reconnection seen from riometer and hard X-ray measurements) and magnetic field reconfiguration/formation of the current system, whereas the long-term current system evolution correlates better with hot plasma fluxes (seen from in situ and soft X-ray measurements). We then discuss how data sets of in situ measurements of magnetospheric substorms can help interpret solar flare data.
