Published: October 2019

Microbes in soil can degrade insoluble inorganic and organic phosphorus, which are components of the soil phosphorus cycle and play an important role in plant growth. Pinus massoniana is a pioneer tree species used for afforestation in southern China and grows in poor, acidic soil. A shortage of available phosphorus in soil limits the growth of P. massoniana. To alleviate this situation, it is necessary to improve soil fertility. A fungal strain (JP-NJ2) with the ability to solubilize phosphate was isolated from the P. massoniana rhizosphere. The ability of JP-NJ2 to solubilize inorganic and organic phosphorus and promote the growth of P. massoniana was evaluated. It showed that JP-NJ2 could grow in NBRIP inorganic phosphate (AlPO4, FePO4·4H2O, and Ca3[PO4]2) fermentation broths, with the highest phosphorus concentration (1.93 mg/mL) and phosphate-solubilizing rate (43.7%) for AlPO4 and in Monkina organic phosphate fermentation broth with a phosphorus concentration of 0.153 mg/mL. The phosphate-solubilizing capability in inorganic and organic fermentation broths was negatively correlated with pH. JP-NJ2-produced acids at a total concentration of 4.7 g/L, which included gluconic (2.3 g/L), oxalic (1.1 g/L), lactic (0.7 g/L), and malonic (0.5 g/L) acids. It prioritized extracellular acidic phosphatase and combined with phytase to solubilize organic phosphates. The fungal suspension and extracellular metabolites from phosphate-solubilizing fungi promoted the shoot length of P. massoniana seedlings by 97.7% and 59.5%, respectively, while increased the root crown diameter by 46.8% and 27.7%. JP-NJ2 was identified as Penicillium guanacastense based on its morphology and phylogenetic analyses of five genes/regions (ITS, ben A, cmd, cox1, and tef). This is the first report on P. guanacastense isolated from pine tree rhizosphere soil in China and its high phosphate-solubilization capability, which promoted the growth of P. massoniana. P. guanacastense JP-NJ2 has potential use as a biological fertilizer in forestry and farming.

Autophagy is initiated by the formation of a phagophore assembly site (PAS), the precursor of autophagosomes. In mammals, autophagosome formation sites form throughout the cytosol in specialized subdomains of the endoplasmic reticulum (ER). In yeast, the PAS is also generated close to the ER, but always in the vicinity of the vacuole. How the PAS is anchored to the vacuole and the functional significance of this localization are unknown. Here, we investigated the role of the PAS–vacuole connection for bulk autophagy in the yeast Saccharomyces cerevisiae. We show that Vac8 constitutes a vacuolar tether that stably anchors the PAS to the vacuole throughout autophagosome biogenesis via the PAS component Atg13. S. cerevisiae lacking Vac8 show inefficient autophagosome–vacuole fusion, and form fewer and smaller autophagosomes that often localize away from the vacuole. Thus, the stable PAS–vacuole connection established by Vac8 creates a confined space for autophagosome biogenesis between the ER and the vacuole, and allows spatial coordination of autophagosome formation and autophagosome–vacuole fusion. These findings reveal that the spatial regulation of autophagosome formation at the vacuole is required for efficient bulk autophagy.
A homeostatic mechanism rapidly corrects aberrant nucleocytoplasmic ratios maintaining nuclear size in fission yeast
Authors: Cantwell Helena , Nurse Paul
Published: October 2019

Nuclear size scales with cell size across a wide range of cell types. The mechanism by which this scaling is maintained in growing cells remains unclear. Here, we investigate the mechanism of nuclear size homeostasis in the simple eukaryote fission yeast, by monitoring the recovery of aberrant nuclear volume to cell volume (N/C) ratios following perturbation. We demonstrate that both high and low N/C ratios correct rapidly, maintaining nuclear size homeostasis. We assess the kinetics of nuclear and cellular growth and of N/C ratio correction, and demonstrate that nuclear and cellular growth rates are not directly coupled. We propose that the mechanism underlying nuclear size homeostasis involves multiple limiting factors implicated in processes including nucleocytoplasmic transport, lipid biogenesis and RNA processing. We speculate that these link cellular size increases to changes in nuclear contents, which in turn lead to changes in nuclear membrane surface area. Our study reveals that there is rapid nuclear size homeostasis in cells, informing understanding of nuclear size control and size homeostasis of other membrane-bound organelles.

Existing measures for the suppression of dust and gas emissions during mass explosions at the quarry of a mining and processing plant were investigated. Measures have been developed to reduce dust and gas emissions, taking into account the analysis of existing measures to suppress dust and gas emissions from mass explosions in the open pit of the mining and processing plant of Lebedinsky GOK. The studies of surface active substances on the wettability of dust particles. In order to improve working conditions, it was proposed to reduce dust and gas emissions by suppressing them at the source of education, using the method of wetting and sticking of dust particles. The proposed engineering - technical solution can be used to reduce dust and gas emissions during massive explosions in the quarries of various mining and processing enterprises. The developed method is proposed to be used to ensure environmental safety and improve working conditions in industries with high dustiness by increasing the efficiency of dust collection.

The reduction of corner car traffic at Kochetovka station is an important component of a set of measures that contribute to improving the processing capacity and rhythm of the station. The main disadvantage of the station is that the station systems are separated by main tracks, which produce significant passenger and freight traffic, and therefore difficult shunting and work with angular gears. In article schemes of processing of angular car streams were considered and the most rational is chosen
Information vs. Automation and Implications for Dynamic Pricing
Authors: Bollinger Bryan K. , Hartmann Wesley R.
Published: October 2019

Essential resources, like electricity and water, can experience rapidly changing demand or supply while the other side of the market is unchanged. Short-run price variation could efficiently allocate resources at these critical times but only if consumers exhibit short-run demand elasticity. The question for firms in these markets has always been how to enable this response. Randomized control trials are increasingly used to test dynamic pricing and technologies that can assist in response by providing information and/or automated response. However, the trials typically do not randomize short-run prices. This paper illustrates how demand from a randomly assigned control group can be used to test the effectiveness of different technologies in increasing short-term price elasticity. To do so, we use a nonparametric control function approach that eliminates the bias inherent in estimating short-term price response using only household random assignment. We find that only automation technology leads to the short-term price elasticity needed to justify real-time pricing.

How Do Gender Quotas Affect Workplace Relationships? Complementary Evidence from a Representative Survey and Labor Market Experiments
Authors: Ip Edwin , Leibbrandt Andreas , Vecci Joseph
Published: October 2019

Gender quotas are frequently proposed to address persistent gender imbalances in managerial roles. However, it is unclear how quotas for female managers affect organizations and whether quotas improve or damage relationships between managers and their subordinates. We conduct a representative survey to study opinions on quotas for female managers and, based upon the survey, design a novel set of experiments to investigate how quotas influence wage setting and effort provision. Our findings reveal that both opinions about gender quotas and workplace behavior crucially depend on the workplace environment. In our survey, we observe that approval for gender quotas is low if women are not disadvantaged in the manager-selection process, regardless of whether there are gender differences in performance. Complementing this evidence, we observe in our experiments that quotas lead to lower effort levels and lower wages in such environments. By contrast, in environments in which women are disadvantaged in the selection process, we observe a higher approval of quotas as well as higher effort levels and higher wages. These findings are consistent with the concept of meritocracy and suggest that it is important to evaluate the perception of gender disadvantages in the workplace environment before implementing quotas.

Managerial Reliance on the Retail Shareholder Vote: Evidence from Proxy Delivery Methods
Authors: Lee Choonsik , Souther Matthew E.
Published: October 2019

Recent studies document the increasing effectiveness of shareholder voting as a monitoring mechanism. Because both directors and the market respond to shareholder votes, management has stronger incentives to influence voting outcomes. We identify one channel through which management can affect voting outcomes: increasing the turnout of (typically management-friendly) retail shareholders. Our study focuses on an observable managerial choice of how to deliver proxy materials to maximize retail turnout. Management can opt to send a full set of proxy materials to all shareholders, which increases retail turnout but also increases printing and mailing costs, or they can send a notice directing shareholders to proxy materials available online, which reduces costs but also decreases retail turnout. We find that managers are more likely to choose to deliver a full set of proxy materials when there are contentious items on the ballot for which they need additional voting support; and, indeed, the resulting support increases the likelihood that voting outcomes will align with management recommendations.

Relational Misperceptions in the Workplace: New Frontiers and Challenges
Authors: Byron Kris , Landis Blaine
Published: October 2019

Understanding the social landscape at work helps employees accomplish organizational goals. A growing body of evidence, however, suggests that people are fallible perceivers of their work relationships. People do not always know how much others trust (or distrust) them, consider them a friend (or enemy), or rely on them for advice or information at work. Such relational misperceptions may be especially likely in the context of work organizations. Here, we develop theoretical accounts to explain how and why employees misinterpret the nature of their relationships with others at work—and what consequences ensue when they do. We direct attention to five key opportunities for future research on when and why relational misperceptions occur and matter in organizations. Building on the small body of organizational research and larger body of nonorganizational research on relationship misperception, we also identify areas that may be fruitful for exploration, highlighting several topics in the organizational literature that could be enlivened by considering the role of relational misperceptions. For example, we consider how employees’ relational misperceptions may affect how influential they are at work, how effectively they lead others, and how they navigate the social landscape in organizations.

The three-mother problem
Authors: Somay Bülent
Published: October 2019

‘Motherhood’, as opposed to ‘fatherhood’, has always been deemed to be something undisputable and certain, and as such, it is considered the main pillar of the institution of the family. There are texts throughout history, however, from the most ‘sacred’ (The Old Testament) to the most profane (contemporary television dramas), that dispute this certainty, thereby opening up the ‘self-evidentary’ nature of the family to critical scrutiny. ‘Motherhood’ is three different things at the same time (genetic, birth and nurturing), and as social and cultural structures get more and more complex, and new biotechnologies develop, these three will grow apart from each other. As things stand, the biological/genetic roots of motherhood (and hence the family) are becoming more and more questionable and insignificant. Furthermore, the cultural/nurturing function of the family is almost ripe to be assumed by networks of chosen human relationships in the near future, in which motherhood becomes a function to be fulfilled by any human being willing to do it, regardless of genetics and gender.
The psychosocial significance of social character, habitus and structures of feeling in research on neoliberal post-industrial work
Authors: Jimenez Luis
Published: October 2019

This article highlights the psychosocial relevance of Erich Fromm’s concepts of ‘social character’ and ‘social change’ to broaden our understanding of the intergenerational traumatic legacy of neoliberalism. As part of this, it also reflects on the psychosocial significance of other related concepts – namely Pierre Bourdieu’s ‘habitus’ and Raymond Williams’ ‘structures of feeling’ – as ways to also acknowledge their significance when related to each other in emerging research on the neoliberal effects of changes in work and identities. This includes secondary analysis of my own earlier research on the psychosocial ramifications of the loss of stable work, changing worker-gendered identities, disrupted affect, community engagement and historical memory within a global context of insecure labour. This is all understood within a theoretical frame that stresses the emerging neoliberal forms of social character in the aftermath of the massive redundancies and unemployment experienced recently in post-industrial working-class communities in the UK.
PRIMER REGISTRO DE PICHE LLORÓN (Chaetophractus vellerosus) PARA EL SUR DE LA PROVINCIA DE SANTA FE, ARGENTINA
Authors: Montani María Eugenia , Romano Marcelo C. , Barberis Ignacio M.
Published: October 2019

En este trabajo se presenta el primer registro de piche llorón Chaetophractus vellerosus (Cingulata, Dasypodidae) para el sur de la provincia de Santa Fe. Hasta el momento, los registros existentes para esta especie de armadillo comprendían un registro fósil y tres actuales para el norte de la provincia, no existiendo datos para la región sur. En junio de 2018, utilizando trampas tipo Tomahawk, se lograron capturar dos ejemplares (macho y hembra) de piche llorón en dos lotes de la Estancia ‘Santa Marta’, ubicada a unos 3 km al sur de la localidad de Christophersen. Existiendo dos poblaciones disyuntas para Argentina, una ubicada al norte-centro del país y la otra al este de la Región Pampeana, este nuevo registro constituye el primero para la Región Pampeana de la provincia de Santa Fe. Si bien coincide con las predicciones del área de distribución ya propuesta, extendería levemente la distribución de la población del norte-centro. La escasez de registros de esta especie para la provincia, dan cuenta de la necesidad de trabajos de campo que estudien la fauna local en una provincia donde más del 80% de los ambientes naturales se han perdido y transformado en agrícolas.
Fabrication of polyimide films with imaging quality using a spin-coating method for potential optical applications

Published: October 2019

Optical polyimide (PI) films were prepared by spin-coating from nearly non-volatile dimethylacetamide (DMAc) solutions. The uniformity of film thickness met the requirements of diffraction imaging quality. The results show that the final rotating speed ω, dynamic viscosity η, and initial polymer solid concentration c are the main factors affecting the film thickness T, and an empirical relationship which describes the film thickness as a function of the measured parameters was established to be

$T \propto {c^{3.473}},{\rm{ }}{\eta ^{0.586}},{\rm{ }}{\omega ^{ - 0.811}}.$

Moreover, the viscosity dependence on concentration is system specific. Unlike traditional photoresist, the thickness uniformity of the PI film is determined by both spinning and precure process, which is intensively discussed in the present work. Uniform, 22-μm thick, PI films with transmitted wavefronts peak to valley (PV) ≤ 1/5 λ and root mean square (RMS) ≤ 1/50 λ were prepared under the optimum process: spin speed 900 rpm, initial fluid viscosity 10,500 cp, final spin time 120 s, precure temperature 70°C, spin process repeated 3 times. The results will find use in the production of optical quality membrane for ultra-lightweight optics or other applications.

Craft Beer's Unlikely Alchemist
Authors: McCulla Theresa
Published: October 2019

In 1965, Frederick (Fritz) Maytag III began a decades-long revitalization of Anchor Brewing Company in San Francisco, California. This was an unexpected venture from an unlikely brewer; for generations, Maytag's family had run the Maytag Washing Machine Company in Iowa and he had no training in brewing. Yet Maytag's career at Anchor initiated a phenomenal wave of growth in the American brewing industry that came to be known as the microbrewing—now “craft beer”—revolution. To understand Maytag's path, this article draws on original oral histories and artifacts that Maytag donated to the Smithsonian Institution's National Museum of American History via the American Brewing History Initiative, a project to document the history of brewing in the United States. The objects and reflections that Maytag shared with the museum revealed a surprising link between the birth of microbrewing and the strategies and culture of mass manufacturing. Even if the hallmarks of microbrewing—a small-scale, artisan approach to making beer—began as a backlash against the mass-produced system of large breweries, they relied on Maytag's early, intimate connections to the assembly-line world of the Maytag Company and the alchemy of intellectual curiosity, socioeconomic privilege, and risk tolerance with which his history equipped him.
Mechanism of SEMA3G knockdown-mediated attenuation of high-fat diet-induced obesity

Published: October 2019

Obesity is a worldwide health problem. Semaphorins are involved in axonal guidance; however, the role of secretory semaphorin 3G (SEMA3G) in regulating adipocyte differentiation remains unclear. Microarray analysis showed that the SEMA3G gene was upregulated in an in vitro model of adipogenesis. In this study, SEMA3G was highly expressed in the white adipose tissue and liver. Analysis of 3T3-L1 cell and primary mouse preadipocyte differentiation showed that SEMA3G mRNA and protein levels were increased during the middle stage of cell development. In vitro experiments also showed that adipocyte differentiation was promoted by SEMA3G; however, SEMA3G inhibition using a recombinant lentiviral vector expressing a specific shRNA showed the opposite results. Mice were fed a chow or high-fat diet (HFD); knockdown of SEMA3G was found to inhibit weight gain, reduce fat mass in the tissues, prevent lipogenesis in the liver tissue, reduce insulin resistance and ameliorate glucose tolerance in HFD mice. Additionally, the effect of SEMA3G on HFD-induced obesity was activated through PI3K/Akt/GSK3β signaling in the adipose tissue and the AMPK/SREBP-1c pathway in the liver. Moreover, the plasma concentrations of SEMA3G and leptin were measured in 20 obese and 20 non-obese human subjects. Both proteins were increased in obese subjects, who also exhibited a lower level of adiponectin and presented with insulin resistance. In summary, we demonstrated that SEMA3G is an adipokine essential for adipogenesis, lipogenesis, and insulin resistance and is associated with obesity. SEMA3G inhibition may, therefore, be useful for treating diet-induced obesity and its complications.

Natural convection effects of the numerical solution for unsteady, laminar, free convection flow over an incompressible viscous fluid past a non-isothermal vertical cone with surface temperature T′w(x) = T′∞ + axn varying as power function of distance from the apex (x = 0) is presented here. The dimensionless governing equations of the flow that are unsteady, coupled and non-linear partial differential equations are solved by an efficient, accurate and unconditionally stable finite difference scheme of Crank-Nicolson type. The velocity and temperature fields have been studied for various parameters Prandtl number, semi vertical angle 0◦ < φ < 90◦ and n. The local as well as average skin-friction and Nusselt number are also presented and analyzed graphically. The present results are compared with available results in literature and are found to be in good agreement.
Radiative Heat Transfer Flow of Micropolar Fluid with Variable Heat Flux in a Porous Medium
Authors: Rahman M. M. M. , Sultana T.
Published: October 2019

A two-dimensional steady convective flow of a micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux has been analyzed numerically. Using Darcy-Forchheimer model the corresponding momentum, microrotation and energy equations have been solved numerically. The local similarity solutions for the flow, microrotation and heat transfer characteristics are illustrated graphically for various material parameters. The effects of the pertinent parameters on the local skin friction coefficient, plate couple stress and the heat transfer are also calculated. It was shown that large Darcy parameter leads to decrease the velocity while it increases the angular velocity as well as temperature of the micropolar fluids. The rate of heat transfer in weakly concentrated micropolar fluids is higher than strongly concentrated micropolar fluids.

On the Dynamics of Controlled Magnetohydrodynamic Systems

Published: October 2019

In this paper we study the long time behavior of solutions for an optimal control problem associated with the viscous incompressible electrically conducting fluid modeled by the magnetohydrodynamic (MHD) equations in a bounded two dimensional domain through the adjustment of distributed controls. We first construct a quasi-optimal solution for the MHD systems which possesses exponential decay in time. We then derive some preliminary estimates for the long-time behavior of all admissible solutions of the MHD systems. Next we prove the existence of a solution for the optimal control problem for both finite and infinite time intervals. Finally, we establish the long-time decay properties of the solutions for the optimal control problem.
Evaluation of the effectiveness of cryptic coloration of the Carolina anole’s skin
Authors: Kiladze A. B.
Published: October 2019

Cryptic coloration of animals’ integument is one of the effective adaptations that allow them to lead an active lifestyle while being protected from natural enemies due to visual disguise. This is achieved by the similarity of body color of a particular individual to the background of various substrates in its environment. The morphological and functional basis of cryptic coloration in vertebrates, including reptiles, is ensured by the skin pigmentation. Using bioinformatic methods, we calculated the skin camouflage index of the Carolina anole (Anolis carolinensis Voigt, 1832) in various conditions of its habitat. The skin camouflage index (Ic) is the ratio of the sum of the average values of rgb coordinates of the skin color to the sum of the average values of rgb coordinates of the color of the external substrate. Ic satisfies the effective level of adaptation to habitat conditions if it falls within the range of 0.80–1.20. It has been shown that rgb-values of the dominant color of the dorsal skin of green anoles slightly differ from the similar parameters characteristic of the deciduous habitat, which is reflected by Ic of its skin (0.94). In the brown anoles on a background of woody substrate, the Ic value of its skin (0.88) is also optimal, since it exceeds the lower limit (0.80), which indicates close values of the sums of the rgb coordinates of the skin color and the color of the external background. In the mixed green-brown anoles, the deciduous habitat is preferable to the woody one. In the first case, Ic (1.11) is in the optimum zone, and in the second case, Ic (0.70) goes beyond the lower limit of the optimum, which indicates a greater vulnerability of the animal to external threats. We have confirmed the relativity of visual hiding of the skin that is effective only in the habitat conditions in which the camouflage abilities of the skin manifest as fully as possible.
The mechanism of adaptation of the organism of patients with chronic heart failure combined with vitamin D deficiency and the morphofunctional state of peripheral blood erythrocytes
Authors: Baryla N. I. , Vakaliuk I. P. , Pоpеl’ S. L.
Published: October 2019

The problem of structural changes in peripheral blood erythrocytes in patients with chronic heart failure in combination with vitamin D deficiency during exercise stress remains insufficiently studied. Vitamin receptors are located on smooth myocytes, endothelial cells, cardiomyocytes and blood cells. It affects the state of the cell membrane, the contractile function of the myocardium, the regulation of blood pressure, cardiac remodeling and reduction of left ventricular hypertrophy. Therefore, it is important to assess the level of vitamin D in blood plasma in individuals with chronic heart failure and to identify the effect of its deficiency on the state of peripheral red blood cells when performing a 6-minute walk test. A total of 75 patients of the main group with chronic heart failure stage II A, I–II functional class with different levels of vitamin D deficiency were examined. The control group included 25 patients with chronic heart failure stage II A, functional class I–II without signs of vitamin D deficiency. The average age of patients was 57.5 ± 7.5 years. All patients were asked to undergo the 6 minutes walking test. The level of total vitamin D in plasma was determined by enzyme immunoassay. Morphological studies of erythrocytes were performed on the light-optical and electron-microscopic level. The obtained results showed that patients of the main group with chronic heart failure had a decrease in vitamin D by 2.2 times compared with the control group. Correlation analysis showed a directly proportional relationship between vitamin D deficiency and the number of red blood cells of a modified form and red blood cells with low osmotic resistance. Dosed exercise stress in patients with chronic heart failure against a background of vitamin D deficiency leads to an increase in the number of reversibly and irreversibly deformed erythrocytes and a decrease in their osmotic stability. This indicates a disorder in the structural integrity of their membrane and can have negative consequences for the somatic health of such patients.
“Witch” and “Shaman”
Authors: Puca Angela
Published: October 2019

From the very birth of the term, Strega (“Witch”) has been used with a negative connotation to describe women with powers aimed at harming people. Strega has its etymological origin in the Latin Strix, the owl believed to feed on human blood. Pop culture, books and media alike, also portrayed the witch as an evil character to the point where it became common parlance to address a person deemed evil as a witch. In the last three decades, with the popularization of paganism and Wicca, the term has been reclaimed and somehow sanitized by Pagans who neutrally describe this figure as someone who has the ability to change reality in accordance with the will. In more recent years, with the spread of shamanism, more practitioners start to either renounce the term “witch” in favour of Sciamano/sciamana (“Shaman”) or use them both to define themselves. By analysing the discourses that practitioners create around the terms “witch” and “shaman”by means of Paul Johnson’s categories, I will illustrate how both terms manifest a form of indigenization and extending. In conclusion, I will argue that indigenizing and extending may be seen as two aspects of the same phenomenon entailing the opening of cultural borders to the outside, reshaping both the imported and exported cultural elements.
Entering the Magic Mists
Authors: Butler Jenny
Published: October 2019

This article explores the ways in which contemporary Pagans in Ireland engage with traditional culture, as well as with notions of the Celtic, in forming identities that are regarded by some practitioners as being indigenous identities. This cultural process at work in the Pagan movement is examined against a backdrop of contested constructions of “Irishness” in different political and sociocultural milieus. Drawing from ethnographic research on the Irish Pagan community, the examination includes examples of mechanisms used by modern Pagans to engage with ancestral and historical cultures. In entering the magic mists to search for symbols and ideas to help connect to the “old religion,” modern Pagans create something new and unique while taking inspiration from the past. This overview of Pagans’ utilization of cultural forms, and their use of tradition, aims to communicate why this creative approach to the past, and resulting formation and maintenance of identities, is culturally significant in the Irish context.

Crisis of Intellectual Culture: on Issue of Approaches to Studying the Problem of Typology
Authors: Tkachev Valery , Suranova Elena
Published: October 2019

The article is devoted to studying the problem of typology of intellectual culture crises. It proves that the intellectual culture as a historical process represents itself as an endless change of cultural forms, in which case each of the forms once emerged, reached its flourishing and died, being replaced by other cultural forms. It emphasizes that crises are intertwined into this process; they appear in cultures inevitably, under certain conditions - when the potential of the former cultural form has not been exhausted yet, and the struggle for its future form is only outlined, but the crises themselves take a short period of time in this process, although they have a complex nature. The article focuses on the fact that the typology of crises should be built, on the one hand, in conjunction with the typology of intellectual cultures and, on the other hand, with the typology of the historical process; there can be a number of such typologies, and this proves that cultures and crises can be classified in a variety of ways. It notes that the typology is a method used to study, compare and describe a variety of processes, including intellectual cultures and their crises, but this method does not exist in a vacuum, it is formed in an environment of idealism and materialism, dialectical and metaphysical methods. The peculiarities of modern typologies stem from the fact that, since the turn of the 19th and 20th centuries, they are under the pressure of the metaphysical method, hence there is their internal need for the culture unification on the grounds close to their ethnicity: the idea of the unity of the cultural process is rejected with the help of these features, and the understanding of the process itself is reduced to the individuality of its cultural forms.
