Why do Informal Sector Competitors Hinder Formal Entrepreneurs More in Some Countries?
Authors: Williams Colin C
Published: October 2020

Objective: The objective of this paper is to evaluate the different explanations provided by competing theories for informal sector competitors being viewed as hindering formal entrepreneurs more in some countries than others.Theoretical background: These theories variously explain such cross-country variations as determined by: economic under-development (modernization theory); government over-interference and high taxes (neo-liberal theory); too little government intervention (political economy theory), or the asymmetry between the laws and regulations of formal institutions and entrepreneurs’ views on the acceptability of participating in the informal economy (institutional theory).Methods: To evaluate these theories, the chosen method focus on World Bank Enterprise Survey data on 31 Latin American and Caribbean countries using binary probit regression analysis.Main results: The findings show significant cross-country differences, ranging from 58.1 per cent of entrepreneurs viewing informal sector competition as a major constraint in Bolivia to 11.1 percent in Dominica. The binary probit regression analysis confirms the modernization and institutional theories, only partially confirms political economy theory, but refutes neo-liberal theory.Theoretical contribution: The paper concludes by discussing the implications for theory and the policy initiatives required to reduce informal sector competition.

Published: October 2020

The melanocortin-4 receptor (MC4R) gene plays an important role in sympathetic nerve activity, as well as adrenal and thyroid function and mediates the effects of leptin on energy homeostasis. This study aimed to investigate the effect of the 642 bpMC4R gene on feed intake, nutrient digestibility, average daily gain (ADG),and feed conversion ratio (FCR)at post-weaned in Bligon goat. Forty-six Bligon were used for the blood sample collection, and genomic DNA was extracted using the Geneaid isolation kit. Feed intake data were collected on 46 Bligon goats kept on 2 different animal houses, including the laboratory’s farm of Faculty of Animal Science Universitas Gadjah Mada (FAS UGM) with n=23 and Banyusoco farm (n=23). Variables observed were feed intake, nutrient digestibility,ADG,and FCR. All samples were genotyped using the PCR-RFLP method with the KpnIenzyme. One SNP was located in the exonic region (g.1079C/T). The t-test analysis revealed a significant association between SNP g.1079C/T and the digestibility of dry matter (DM), organic matter (OM),and total digestible nutrient (TDN) of Bligon goats at 7 months of age kept on FAS UGM, as well as the digestibility of DM, crude protein (CP), nitrogen-free extract (NFE),and TDN of Bligon goats at 7 months of age kept on Banyusoco. In conclusion, it is possible to use SNP g.1079C/T for animal genotyping and asaMAS for nutrient digestibility in Bligon goats

Published: October 2020

Research on fermentation time and the addition of milk powder to egg albumen is still limited. The purpose of this study was to determine the antioxidant activity and chemical characteristics of fermented egg albumen using different levels of full cream milk powder and different microbial fermentation times. This study used a completely randomized factorial pattern design, 4 x 5 treatments with 4 replications. Research materials include egg albumen, full cream milk powder and mixed Lactic Acid Bacteria (L. bulgaricus, L.achidopillus, and Streptococcus thermopillus). The research treatments were the addition of powdered milk in different level (%) including, 0, 2, 4 and 6. Fermentation times were 0, 12, 24, 36, and 48 h, respectively. The results showed that the addition of powdered milk in different level and fermentation time had no significant effect on the antioxidant activity. The addition of different-level powdered milk was not significant on the glucose content and total protein, but it was very significant (P<0.01) on water content. The fermentation time had a very significant effect (P<0.01) on glucose levels and total protein, but it had no significant effect on the water content of albumen fermentation. Antioxidant activity did not change during the fermentation time and the addition of different-level milk powder. The 24 h fermentation time could reduce the total protein and glucose levels of egg albumen. Adding 2% milk powder could reduce the water content of egg albumen fermentation.

A Framework of Nonequilibrium Statistical Mechanics. II. Coarse-Graining
Authors: Montefusco Alberto , Peletier Mark A. , Öttinger Hans Christian
Published: October 2020

For a given thermodynamic system, and a given choice of coarse-grained state variables, the knowledge of a force-flux constitutive law is the basis for any nonequilibrium modeling. In the first paper of this series we established how, by a generalization of the classical fluctuation-dissipation theorem (FDT), the structure of a constitutive law is directly related to the distribution of the fluctuations of the state variables. When these fluctuations can be expressed in terms of diffusion processes, one may use Green–Kubo-type coarse-graining schemes to find the constitutive laws. In this paper we propose a coarse-graining method that is valid when the fluctuations are described by means of general Markov processes, which include diffusions as a special case. We prove the success of the method by numerically computing the constitutive law for a simple chemical reaction

Simultaneous improvement of mechanical and conductive properties of poly(amide-imide) composites using carbon nano-materials with different morphologies
Authors: Fang Yawen , Yu Huang , Wang Yanbin , Zhang Zhehao , Zhuang Changlong , Fang Gui , Luo Zhonglin , Zhang Bo , Wang Biaobing
Published: October 2020

Two conductive carbon materials, one with a beaded-like structure (carbon black, ECP) and another with tube-like structure (functionalized multi-walled carbon nanotubes, FMWCNTs), were added into a poly(amide-imide) (PAI) matrix. Combining the advantages of ECP (good compatibility) and FMWCNT (high conductivity), the conductivity was improved from 3.7 S m−1 for PAI/FMWCNT polymer composites to 100 S m−1 for PAI/FMWCNT/ECP ternary conductive polymer composites, much higher than that of the sum of PAI/ECP and PAI/FMWCNT. The tensile strength increased from 40 to 70 MPa. The improved conductive and mechanical properties were mainly due to much more intensive conductive network produced in the PAI/FMWCNT/ECP ternary composites, which is useful for electron flow and stress spread. The number of hydrogen bond was increased by adding ECP into PAI/FMWCNT binary composites, and played an important role in forming the unique morphology as evident by Fourier transform infrared spectrometry (FTIR) and X-ray diffraction (XRD) measurements. These conductive composites have potential for flexible electronic applications.
A rare case of fructose-1,6-bisphosphatase deficiency: a delayed diagnosis story
Authors: Ergoren Mahmut Cerkez , Tuncel Gulten , Sag Sebnem Ozemri , Temel Sehime Gulsun
Published: October 2020

Objectives

Fructose-1,6-bisphosphatase deficiency (FBPase deficiency, OMIM 229700) is an early-onset rare genetic disorder caused by mutations in the FBP1 gene.

Case presentation

Our patient was 17-years-old when she was diagnosed with the disease. Initial sequencing analysis with Ion Torrent technology failed to detect the gross deletion that covered complete exon 2 (c.-24-26_170 + 5192del) of FBP1 gene and caused the delay in diagnosis. Deletion was then detected when sequencing was performed in an Illumina MiSeq platform.

Conclusions

This case emphasizes the importance of sequencing data analysis for precise diagnosis of rare diseases and therapy planning.
Influence of varying magnetic field on nonlinear wave excitations in collisional quantum plasmas
Authors: Roy Debasish , Sahu Biswajit
Published: October 2020

The nonlinear wave excitations arising from the spatially varying magnetic field in the quantum plasma environment are investigated in the frame work of quantum hydrodynamic model. In the weakly nonlinear, dispersive and dissipative limit it is shown that the varying magnetic field and collision-induced excitations can be described by a modified form of Korteweg-de Vries–Burgers’ type model equation. It is found that the dissipation terms (Burgers’ and collisional term) arise due to spatially varying magnetic field and the ion-neutral collisions. The numerical solutions of this equation predict that the localized soliton solutions decay algebraically due to the combined effect of varying magnetic field and collision by radiating oscillatory pulses behind the propagating soliton.
Ethyl acetate extract from Cistus x incanus L. leaves enriched in myricetin and quercetin derivatives, inhibits inflammatory mediators and activates Nrf2/HO-1 pathway in LPS-stimulated RAW 264.7 macrophages
Authors: D’Ambrosio Mario , Bigagli Elisabetta , Cinci Lorenzo , Gori Antonella , Brunetti Cecilia , Ferrini Francesco , Luceri Cristina
Published: October 2020

Cistus x incanus L. is a Mediterranean evergreen shrub used in folk medicine for the treatment of inflammatory disorders but the underlying mechanisms are not fully understood. We therefore investigated the anti-inflammatory effects of an ethyl acetate fraction (EAF) from C. x incanus L. leaves on lipopolysaccharide (LPS) activated RAW 264.7 macrophages. HPLC analysis revealed myricetin and quercetin derivatives to be the major compounds in EAF; EAF up to 1 µM of total phenolic content, was not cytotoxic and inhibited the mRNA expression of interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2) (p < 0.05) and the production of prostaglandins E2 (PGE2) (p < 0.05). Meanwhile, EAF triggered the mRNA expression of interleukin-10 (IL-10) and elicited the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2), as well as the expression of its main target gene, heme oxygenase-1 (HO-1) (p < 0.05). These data indicate that EAF attenuates experimental inflammation via the inhibition of proinflammatory mediators and at least in part, by the activation of Nrf2/HO-1 pathway. These effects are likely due to myricetin and quercetin derivatives but the role of other, less abundant components cannot be excluded. Further studies to confirm the relevance of our findings in animal models and to highlight the relative contribution of each component to the anti-inflammatory activity of EAF should be conducted.
Solubilization, Hansen solubility parameters and apparent thermodynamic parameters of Osimertinib in (propylene glycol + water) cosolvent mixtures
Authors: Shakeel Faiyaz , Anwer Md. Khalid , Haq Nazrul , Alsarra Ibrahim A.
Published: October 2020

The solubilization, Hansen solubility parameters (HSPs) and apparent thermodynamic parameters of a novel anticancer medicine osimertinib (OMT) in binary propylene glycol (P) + water (W) cosolvent mixtures were evaluated. The mole fraction solubility (x
e) of OMT in various (P + W) cosolvent mixtures including neat P and neat W was determined at T = 298.2–318.2 K and p = 0.1 MPa by applying a saturation shake flask method. HSPs of OMT, neat P, neat W and (P + W) cosolvent compositions free of OMT were also estimated. The x
e values of OMT were regressed with Van’t Hoff, modified Apelblat, Yalkowsky-Roseman, Jouyban-Acree and Jouyban-Acree-Van’t Hoff models with an average errors of <3.0 %. The highest and lowest x
e value of OMT was estimated in neat P (2.70 × 10−3 at T = 318.2 K) and neat W (1.81 × 10−5 at T = 298.2 K), respectively. Moreover, HSP of OMT was found to be closed with that of neat P. The solubility of OMT was found to be increased significantly with an increase in temperature and P mass fraction in all (P + W) cosolvent compositions including neat P and neat W. The results of activity coefficients suggested higher molecular interactions in OMT-P combination compared with OMT-W combination. The results of thermodynamic studies indicated an endothermic and entropy-driven dissolution of OMT in all (P + W) cosolvent compositions including neat P and neat W.

Humanizing Industrialization?: Japanese Productivity Methods, Ethiopian Factories, and Low Modernism in Foreign Aid
Authors: Fourie Elsje
Published: October 2020

The past decade has seen a gradual convergence between the modernizing, top-down development agendas associated with “new donors” to Africa and the human development agenda more commonly linked to traditional donors. But while instruments such as the Sustainable Development Goals now demand both industrialization and empowerment, donors still struggle to reconcile these competing expectations. This article uses a variety of qualitative data to examine one such project: the attempted transfer of Japanese management techniques (or kaizen) to workplaces across Ethiopia as part of Japanese official development assistance. Asking why and how the Japanese and Ethiopian governments pursue these aims, the article finds an intervention that is low modernist in design: its goals and logics are modernist but tempered by a respect for local knowledge and a preference for evolutionary over revolutionary change. The fact that Japan is the donor to promulgate such a paradigm is no coincidence, I find, given the historical origins of kaizen and Japan’s long-standing hybrid role in international development debates. Low modernist interventions such as Ethiopian kaizen demonstrate the utility of moving beyond dichotomies (China/West, growth/equity, efficiency/empowerment). But in both Ethiopia and the Japanese aid apparatus, powerful centrifugal forces still make low modernism a difficult balancing act to achieve.
Agricultural Citizenship and the German Winemakers of Los Angeles County, 1853–1891
Authors: Ornelas-Higdon Julia
Published: October 2020

Newly arrived in 1850s California, a group of German immigrants adopted viticulture and founded Anaheim as a wine colony. Along with industry leaders and boosters, they helped expand the region’s commercial wine industry from its Spanish and Mexican roots, using viticulture as a vehicle of Americanization in California. Per the observations of wine industrialists, trade groups, and boosters, these German immigrants represented the American ideal of agricultural citizenship as a barometer of belonging in California. This notion was rooted in large-scale land ownership and relied on modern technology, shipping infrastructure, agricultural science, marketing, and wage workers. Significantly, Anaheim’s German wine growers also employed modern agribusiness techniques that laid the foundation for the citrus industry in the early twentieth century.
“Oppressed and Destroyed”
Authors: Montgomery S. Janelle
Published: October 2020

In 1932 in Depression-era Los Angeles, Mexican muralist David Alfaro Siqueiros took advantage of a unique site on Olvera Street to confront Los Angeles’s establishment on behalf of not only Mexican Americans in California but the proletariat everywhere. The resulting mural, América tropical, challenged Los Angeles’s sanitized history of its Mexican past and the persecution of the city’s immigrant working class. The establishment responded by requesting that Siqueiros leave the country and by whitewashing the mural. In the late 1960s, the white overpaint began to fade, and América tropical re-emerged to play a part in another chapter of the politics of race and class in Los Angeles. Revisiting the mural and its destruction illuminates the complex interplay between outdoor art and civic discourse.

Diversity and relative autonomy of the representation of the Ukrainian population about social inequality
Authors: Kovalisko Natalia , Makeev Serhii
Published: October 2020

In modern literature, the dependence of inequality estimates on the situation in which the individualis immersed, i.e. on some constellation of place and time circumstances which determines the degree of availability of vital benefits and opportunities, has been empirically confirmed. Experiencing and comprehending this situation exfoliates into experience, determines the modality of personally expressed value-colored judgments.exfoliated into experience, which determines the modality of personally expressed value-based judgments. In general, although the perception of inequality does not coincide with "reality", it remains significant regardless of this, as it can be the immediate motive for political action — protest voting in elections, participation in actions demanding a change in the current state of income and welfare. The article substantiates the approach to the perception of inequality as a self-sufficient factuality. The data obtained in the survey on the module "Social Inequality–V" of the International Social Research Project (ISSP) show that respondents are of different categorical assessment of inequality to two objects: the country as a whole and their specific life situation. Since the range of perception always manifests itself in the range from “deep inequality” to “non-recognition of inequality,” the social space is differentiated into “worlds of inequality” that do not coincide in scale. Based on the answers to the questions about the placement on specific levels of the social ladder, the financial situation of the family and belonging to a particular class, quantitative assessments of each of these worlds have been made. At the same time, the distribution over the "worlds of inequality" obtained in the quantitative survey is nothing more than an approximate assessment of the "real" stratification of Ukrainian society. The results of the correspondence analysis between the estimates of inequality and the 34 predictors of their passing have been described and interpreted.
Global risks and their systemic consequences
Authors: Chepurko Gulbarshyn
Published: October 2020

The purpose of the article is to clarify the essence of global risks. Global risks are considered in terms of the ratio of the likelihood and consequences of adverse events that can cause harm or damage, while being global in nature and impact. The systemic nature of global risks has been identified as a defining feature of their current manifestation. A systematic approach to determining the source of modern global risks is used. It is defined that the main risks of the last decade are the risks of the ecological, geopolitical and social spheres, while technological risks are also being developed. It is noted that overall picture of global trends and global risks is constantly changing due to distinction of risks with extremely high growth rates. WEF has determined the forecast for 2020 regarding global trends and global risks is analyzed. For the first time in the ten-year history of global risks study, environmental threats took all positions within the top five risks of high probability of occurrence and three positions in the top 5 risks in terms of their impact. Other two major risks in terms of impact are the usage of weapons of mass destruction and the water crisis. The environmental risks by probability of their occurrence include: weather cataclysms, failure in fight against climate change, natural disasters, reduction of biodiversity, and anthropogenic environmental disasters. Three of these, related to failures in the fight against climate change, reduction of biodiversity and weather cataclysms — are also among the five risks with the most negative consequences. The growing risks of stagnation in the global economy were also noted, including those caused by increasing trend towards emphasizing national economic policy, and local political polarization in consequence of socio-economic intensifying inequality, as well as dissatisfaction of citizens with the way governments try to solve this problem. It is defined that environmental risks, including the ones caused by climate change, are dangerous to that extent that the response to them requires not just a set of measures, but changes in consumption patterns.

On extremal subspaces for widths of classes of convolutions
Authors: Parfinovich N.V.
Published: October 2020

We obtained the exact values of the best $L_1$-approximations of the classes $K*F$ ($r\in \mathbb{N}$) of periodic functions $K*f$ such that $f$ belongs to a given rearrangement-invariant set $F$ and $K$ is $2\pi$-periodic, not increasing oscillation, kernel, by subspaces of generalized polynomial splines with nodes at points $2k\pi / n$ ($n\in \mathbb{N}$, $k\in \mathbb{Z}$). It is shown that these subspaces are extremal for the Kolmogorov widths of the corresponding functional classes.

Published: October 2020

Background

Not much is known about the correlation between gaming problems and substance use across different countries. This paper presents cross-national analyses of different gaming indicators and their relationship to substance use.

Methods

Based on data from the 2015 ESPAD study, differences in the relationship between gaming and substance use across 35 countries were analysed using multi-level logistic regression, using substance use as an individual level predictor, economic wealth as a country-level predictor and a combined problem gaming indicator as the outcome.

Results

Multi-level logistic regressions revealed significant correlations between individual substance use and gaming problems, which varied across countries and were moderated by economic wealth. Students who used alcohol, tobacco or cannabis and who lived in high-income countries had a smaller risk of scoring positively on a combined problem gaming indicator than students who used alcohol, tobacco or cannabis and who lived in less prosperous countries.

Discussion

Different gaming indicators varied substantially across countries, with self-perceived gaming problems being more common in countries with a low prevalence of gaming. Significant cross-level effects demonstrate the need to take the societal context into account when the relationship between problem gaming and substance use is analysed. Prevention measures need to take the fact into account that patterns of substance use among problem gamers vary across countries.

Absztrakt:

Az acromegalia ritka, de klinikailag fontos betegség, amelyet a növekedési hormon
és az inzulinszerű növekedési faktor-1 krónikusan magas szintje okoz. Számos
tünete és komplikációja lehet, amelyek közül a diabetes mellitus gyakori
szövődmény. A növekedési hormon különböző mechanizmusokon keresztül hathat a
szénhidrát-anyagcserére és idézhet elő inzulinrezisztenciát. Cikkünkben egy
acromegaliás beteg esetét dolgozzuk fel, kiemelve a beteg
szénhidrátanyagcsere-eltéréseit, valamint az eset kapcsán ismertetjük az
acromegalia kezelésében használt terápiás lehetőségeknek a glükózháztartásra
gyakorolt hatását a nemzetközi irodalom áttekintésével. A contrainsularis hatású
növekedésihormon-túlprodukció rontja a glükóztoleranciát. Ennek megfelelően a
kórosan fokozott növekedésihormon-termelést csökkentő különböző kezelési módok
(mint a sebészi vagy radioterápia, illetve a gyógyszeres kezelés bizonyos
típusai) hatására javul a szénhidrát-anyagcsere. Ugyanakkor a gyógyszeres
terápiás lehetőségek közül az első generációs szomatosztatinreceptor-ligandok az
esetek kis részében ronthatják a szénhidrátháztartást, míg a második generációs
pazireotid a betegek jelentős részénél hyperglykaemiát okoz. Az acromegaliás
beteg kezelése komplex feladat, több diszciplína képviselői (endokrinológus,
idegsebész, radioterapeuta, az egyes speciális problémák megoldásában részt vevő
orvosok, fogorvosok) végzik, de a kezelés összefogásáért az endokrinológus
szakorvos a felelős. Az acromegaliának, illetve a kezelés szövődményeinek,
kiemelten a szénhidrátháztartás zavarainak ellátásában a háziorvosnak is fontos
szerepe van, ehhez pedig ismernie kell a kezelési módozatok főbb pontjait és
potenciális mellékhatásait. Orv Hetil. 2020; 161(40): 1724–1729.

Authors: Funes Guillermo , Pocasangre-Orellana Xochilt
Published: October 2020

Lontra longicaudis Olfers, 1818 (Neotropical Otter) has been poorly studied in El Salvador. We report sightings and traces of L. longicaudis which were found in Río Angue, in the department of Santa Ana, and Río Sapo, Río Negro, and Quebrada de Perquín, in the department of Morazán. Moreover, we review the sight records of the species in the scientific literature, the mammal collection of the University of California, Los Angeles, and citizen reports with verifiable evidence. This is the first compilation of information on L. longicaudis occurrences in El Salvador.
Injury Rate of the Bronze Age Population from the Lower Volga Area
Authors: Pererva Evgeny
Published: October 2020

Introduction. The research objective is to determine and analyze data on traumatic phenomena found in the bones of the Bronze Age population originating from the burial sites of the Lower Volga area.

Methods. The identification of traumatic injuries in anthropological materials was based on the works and recommendations in the field of special traumatology and pathology used in forensic medicine and bioarchaeological reconstructions. Statistical analysis was carried out using one-dimensional methods and nonparametric Mann-Whitney and Kruskal-Wallis criteria.

Analysis. The study of paleoanthropological materials of the Early Bronze Age shows that injuries are found only on skulls. The total injuries of the adult population in the group are at the level of 15.2%. Of the 5 injuries on the bones of the Early Bronze Age, 1 belongs to a woman and 4 – to men. Severe injuries are discovered in adult individuals. General injuries are not numerous and reach 24.8%. In the series of the Late Bronze Age, injuries on the bone remains of children are also not detected. The frequency of occurrence of traumatic objects on anthropological materials of II millennium BC is insignificant, only 18 cases, which is 16.1% of the total number of adult individuals.

Results. In the studied series, sex dimorphism and differences in the nature of distribution of injuries between groups of different ages are not statistically revealed, which indicates similar social roles of the male and female population in the Bronze Age. No injuries are detected in children. The frequency of perimortem injuries is extremely low. Non-lethal (uniform, with traces of healing) injuries on the skull bones and postcranial skeleton dominate in the series, which indicates a similar level of technological development and medical knowledge in the Bronze Age population. Injuries of the Bronze Age of the Lower Volga region can be described as every day or civilian trauma due to the development of labor production or social tension in the groups.
Demography of the Crimean Tatar Population of the 16th – 18th Centuries (According to the Materials of the Necropolis near the Village of Fontan)
Authors: Popov Aleksandr
Published: October 2020

Introduction. The article discusses the demographic characteristics of the population of the Crimean Tatar village of Karmysh-Kelechi of the 16th – 18th centuries based on the materials of Fontan-1 burial ground.

Methods and materials. Research procedures included the construction of mortality tables that characterize the sequence of extinction of a certain generation of people or general patterns of changes in mortality for cohorts of the population with a similar order of extinction. The mortality tables contain various demographic indicators that were analyzed during the study.

Results. As a result of the analysis, the author has found out the main demographic indicators of this population. These include a high mortality rate of children from newborn to 4 years with a predominance of children under 1 year; a slight predominance of the male population over the female; the average age of death for children was 20.6; the average age of death of the adult population – 36.5.; men lived three years longer than women. Moreover, in women, two peaks of mortality occur during the childbearing period and are probably associated with the stress that accompanies the female body during pregnancy and childbirth. The distribution of the male mortality reflects the natural process of aging and death. It is possible that the high infant mortality rate, as well as the lower average age of death, may be due to adverse external factors. The comparative analysis of the demographic indicators of the population who left Fountain-1 burial ground with synchronous groups shows that they all correspond to the indicators of populations of the Early Modern times and do not get out of the general context.
Cultural and Morphological Differentiation of the Population of the Middle Bronze Age in the Lower Volga Region and Adjacent Territories
Authors: Balabanova Mariya
Published: October 2020

Introduction. The author of the article considers the cultural and morphological differentiation of the population of the Middle Bronze Age in the Lower Volga region and adjacent territories. Methods and materials. The researcher has analyzed 18 male craniological series, which were compiled from published and new materials. The authors contribution is more than 230 skulls. The comparative analysis has been carried out by the canonical method to solve the problem. The Mahalanobis proximity distance matrix has been processed by cluster analysis to visualize the results as a dendrogram. Analysis. The results of the comparative analysis reveal a significant morphological similarity of the population of the Lower Volga region catacomb circle cultures who did not practice the deformation custom, except for a burial ground series of the Volga-Don variant. First of all this similarity can be explained by the commonality of the genetic substrate. A series of skulls with traces of artificial deformation has a certain similarity, the distribution of intergroup variability can be associated not only with the modeling effect of the deforming structure on the craniological patterns, but also the genetic relationship of this group of populations. Results. The series of the Volga-Don variant is more similar to the Poltavka culture series in the Lower Volga region, which confirms the hypothesis made by some scientists about the evolutionary nature of the development of cultural elements from the earlier Poltavka to the later Volga-Don ones. This group has some similarities with the late Ymna population of the Lower Volga region. As for the population of the PostCatacomb time (Krivolukskaya and Lola cultures), they differ from the rest of the population by a longer and narrower skull, which is apparently related to the foreign cultural component that took part in the origin of these populations.

Published: October 2020

With the amendment of the Public Official Election Act, the age of voting in an election was changed from 19 years old to 18 years old beginning in the 21st National Assembly election on April 15, 2020. The purpose of this study was to explore the direction of democratic citizenship education for youth with developmental disabilities who have the right to vote. Recognizing that t the expansion of youth political participation is a condition for a democracy to be realized, related laws and policies on the right for students with disabilities to participate were confirmed. In addition, we reviewed the content and scope of democratic citizenship education in the basic curriculum for special education. Finally, through election education conducted at special education schools among students with intellectual disabilities. we sought democratic citizenship education methods using creative experience activities. Based on this, we argued that the exercise of suffrage by adolescents, with disabilities was not enough to teach them how to participate in elections. Democratic citizenship education that recognizes and acts as a political subject was necessary, and the tasks for its implementation were discussed.
