Wild Rice Lakes in Comparison to Mapped Surficial Sands in Minnesota
Authors: Swenson Michael
Published: December 2023

Several recent studies have considered the distribution of wild rice (Zizania palustris) compared to a variety of physical and watershed parameters. However, the distribution of wild rice has not been systematically compared to the surficial geology. In this study, a relatively comprehensive list of identified wild rice lakes in Minnesota was compared to the mapped areas of surficial sands. Wild rice is significantly more likely to occur on basins which are within or adjacent to mapped surficial sands. Statewide, an odds ratio of 2.1. indicates that a given lake within the mapped surficial sands has more than twice the odds of wild rice occurrence than a lake outside of the mapped surficial sands. The correlation observed here between mapped surficial sands and wild rice presence suggests that a groundwater-surface water interaction may have more widespread importance for sustaining wild rice populations than previously considered.
From Wasteland to Tourist Attraction: The Creation of Everglades National Park
Authors: van der Valk Arnold
Published: December 2023

It took more than 50 years to change public perception of the Everglades from a wasteland that needed to be drained to a valuable natural resource that needed to be preserved as a National Park. The first attempts to stop the ongoing drainage of the Everglades started in the first two decades of the twentieth century. These early anti-drainage campaigns were led by progressive activist and journalist Frank Stoneman, Seminole activist Minnie Moore-Willson, and botanist John Kunkel Small. Their efforts failed. It was not until Ernest F. Coe moved to Miami in 1925 and established the Everglades National Park Association in 1928 that the movement to turn the Everglades into a national park made considerable progress. Coe first worked with fledgling U.S. National Park Service officials to get federal legislation passed in 1934 to establish an Everglades National Park. In parallel, he worked with Florida politicians, especially Governor and later U.S. Senator Spessard Holland, to get State support. While the National Park Service recognized the ecological significance of the Everglades, the State of Florida supported the Park’s creation primarily as a tourist attraction. To establish the Park, Florida eventually agreed to donate hundreds of thousands of acres of state land in the Everglades to the Federal government plus two million dollars to buy additional private land. Despite numerous setbacks, Everglades National Park was dedicated by President Harry S. Truman in December 1947. It was America’s first ecological park and the first to preserve a wetland.
E. Gaskell’s Short Story “The Crowley Castle”: Traditional Content in a New Sensational Form
Authors:   Perm State University, Firstova Maria Yu.
Published: December 2023

The article deals with the short story "The Crowley Castle" by E. Gaskell (1863). The use of elements of sensational poetics in the artistic depiction of the extinction history of a noble family is investigated: crime, mystery, the ruins of an ancient castle, which is new in the work of the writer in the 1860s. Attention is paid to the author's analysis of the causes of the crime: rational and irrational, the psychology of the criminal. The emergence of a new negative heroine, brought to the fore by Gaskell, is revealed. The commonality of the plot elements of Gaskell's story and the novel by Leo Tolstoy's "War and Peace" in the inability of the heroines to manage the surging feelings due to inexperience and life circumstances. An appeal to the traditional for the writer themes of motherhood and the need to follow moral Christian values within the framework of sensational poetics is analyzed.
Russian Intertext in Pounds’s Poem “The Cantos” (The Image of the Russian Revolution in Canto XVI
Authors:   Perm State University, Bratukhina Liudmila V.
Published: December 2023

The article is devoted to the analysis of the Canto XVI fragment from E. Pound's poem The Cantos, which depicts the events of the Russian February and October revolutions of 1917. As a necessary context, the political views of the American author are given, as well as the memories of Russian and foreign eyewitnesses of the events, which allow us to assess the objectivity of the depiction of ambiguous historical facts in the poem, and in addition to trace the sources from which Pound drew information. The author notes the originality of the punk style of presentation, which violates the chronological sequence of events, as well as the inclusion of the events of the Russian revolutions in the context of the era of the World War I. The conclusion is made about E. Pound's critical attitude to the Russian Revolution due to his specific political views.
Elizabeth Gaskell’s Novels and the Issues of Women’s Education in Victorian England
Authors:   Perm State University, Firstova Maria Yu.
Published: December 2023

The article examines E. Gaskell's artistic study of the problems of female education and the work of middle- and working-class women outside home in the Victorian period in the novels Cranford (1853), Ruth (1853), North and South (1853) and Wives and Daughters (1865). The analysis has revealed that the author’s depiction of the shortcomings of the existing system of women’s education in Britain is based on the principles of social realism. The main negative feature of education for women, according to Gaskell, is its unsystematic nature, which prevents women from developing their talents and abilities, as well as getting a job outside home. There is no detailed image of a governess or a female teacher in the writer’s works. This peculiarity of her novels can be interpreted as a deliberate lack of attention to this profession, common among female representatives of the middle class, either as a result of its unattractiveness for the author, or because of the full development of the topic by her contemporaries in the English literature. Within the frames of the social novel, Gaskell also turns to a critical analysis of vocational education for working-class women, pointing out the exploitation of heroines hidden behind the mask of apprenticeship. The images of male teachers created by the author, for whom professional activity becomes an opportunity for self-realization, are also of interest.
The Intermadial Transition of Pink Floyd’s Mother in The Wall by A. Parker (1982)
Authors:   Perm State University, Gerasimova Aleksandra D. , Khokhryakov Andrei L. ,   Perm State University
Published: December 2023

The article considers the problem of transforming a piece of rock-poetry into an extra-meaning element in cinematography – using the example of the song Mother (R. Waters, 1979) by Pink Floyd, as a part of the film Pink Floyd: the Wall (dir. A. Parker, 1982). Along the song lyrics and the video footage, the article examines the film script, promoting the ‘songwriter – screenwriter’, ‘screenwriter – film director’, and ‘songwriter – film director’ interaction, resulting in a further perspective, introducing new characters, setting ties with other parts of the film. By combining the Mother lyrics and their visual implementation, the film unwinds the hidden polemics of the philosophical concepts of S. Freud, C. Jung and E. Fromm, only hinted in the lyrics. The technique of cross-cutting favours the non-verbal communication with the audience, pushing the boundaries of the film into a broader art object. The authors of the article reveal various forms of critical appreciation, born through inter-medial transition of the song lyrics into sound- and visual production.

The Meaning of the Maternal Image in the Children’s Literature by Edith Nesbit
Authors:   Southern Federal University, Kriukova Vera G.
Published: December 2023

The article discusses the way the maternal figure is portrayed by Edith Nesbit, one of the most celebrated children`s author. Throughout much Victorian literature, motherhood was exemplified as a center of morality and virtue. At the same time Nesbit was content with trying on the image of «the new woman». As a result, the representation of mothers in her books is quite ambiguous; they incorporate both the features of angelic femininity and of a new feminist ideal with regenerative power. As E. Nesbit`s relationship with her mother was complex, she subconsciously looked for mother substitute and expressed it in a metaphorical way in her children`s literature.

The Motive of Imprisonment on Joan Rhys’s Short Stories “From a French Prison”, “The Sidi”, “Outside the Machine”
Authors:   Southern Federal University, Matiunina Tatiana S.
Published: December 2023

The article examines the motive of imprisonment (supervision and punishment) in the concept of Jean Rhys’s short stories written in the first half of the XX century. The placement of female (Inez, Madame Tavernier, Mrs. Murphy) and male (the old man and the boy, Sidi) characters in the closed loci of the hospital and prison is seen as an emblem of alienation and identity crisis. The possibilities of philosophical and psychological interpretation of the imprisonment, the key leitmotif of the British writer’s stories, and the accompanying motives of loneliness, accidental encounter, non-involvement, guilt, inner human freedom and existential insight are analyzed in detail. The hospital/prison space turns out to be symbolic, irrational. It acquires metaphysical meaning, correlates with the key ideas of the French philosopher Michel Foucault. Special attention is paid to the representation of the motive of imprisonment in the poetics of the stories «From a French Prison», «The Sidi», «Outside the Machine» (internal psychologism, the unreliability of the narrator, the accentuation of detail).
The Rite of Initiation in Romantic Works of Russian and Foreign Authors of the XIXth Century
Authors:   Kaluga State University in the name of K. E. Tsiolkovsky, Oksenchuk Vera N.
Published: December 2023

The relevance of this paper is due to the fact that researchers of the rite of initiation in literary works have mostly ignored the works of the XIX century, focusing on the XX century. The aim of the work: to analyse how the initiation of the main characters occurs in the works of V. Zhukovsky and D. Byron. The material basis of the study was formed by the works of the following authors: A. Gennep, I.V. Vipulis, M. Eliade, G.V. Grinenko, T. I. Lipich, V. G. Simondon. The conclusion is that Harold and Conrad, the main characters of D. Byron's works, do not completely pass the initiation rite, as the experience gained within the liminal phase destroys them. In V. Zhukovsky's Svetlana, on the contrary, the protagonist undergoes a full initiation, as a result of which she receives new emergent qualities.

Published: December 2023

Studies of the formation of microstructure of grinding balls from the rejects of rail steel were carried out during their quenching in various polymer media. At the first stage, based on studies of the cooling capacity of solutions of polymers PCM and Thermovit with varying concentrations and temperatures, the authors constructed the cooling curves of grinding balls made of K76F rail steel. It was found that at concentration of these polymers in an aqueous solution of 2 and 4 %, cooling rate of grinding balls made of K76F steel is almost identical at solution temperatures of 20 and 30 °C and significantly decreases when the temperature of the polymer solution increases to 40 °C. At the same time, the most noticeable decrease in the cooling rate is characteristic of PCM polymer with its concentration at the level of 2 %. At the second stage, the authors carried out metallographic studies of the microstructure of grinding balls made of K76F rail steel, which were quenched in laboratory conditions using polymers PCM and Thermovit with concentrations of 2 – 4 % and temperature of 20 – 40 °C. As a result, it was determined that the use of the PCM solution for quenching balls provides a significantly higher quality of microstructure and hardness of heat-treated balls compared to the use of the Thermovit polymer. At the same time, varying the concentration and temperature of the PCM polymer quenching medium allows one to obtain grinding balls with different performance characteristics that determine the potential areas of their application. Thus, quenching of balls in a solution of the specified polymer with concentration of 2 % and temperature of 20 – 30 °C ensures the production of balls with high hardness (corresponding to the IV hardness group according to the state standard GOST 7524 – 2015), and the use of a solution of the same polymer with concentration of 4 % and temperature of 20 – 30 °С for quenching creates the possibility of producing balls with lower hardness, but potentially high impact resistance.
Structure and properties of low-alloy steel 10G2FBYu after rolling in embossed rolls under conditions of electroplasticity
Authors: Pochivalov Yu. I.
Published: December 2023

The article describes the features of grain structure formation and mechanical properties of low-alloy steel 10G2FBYu after rolling in flat and embossed rolls under the conditions of ordinary and electroplastic deformation. When rolling in embossed rolls, a significant non-uniformity of deformation is achieved over the rolling cross-section, expressed in localized macroshifts directed at an angle of 45° to the rolling plane. It is shown that local shear deformation during rolling in embossed rolls leads to an increase in the ultimate strength of the steel under study with a decrease in plasticity of the rolled material. Rolling 10G2FBYu steel in embossed rolls under conditions of electroplasticity provides maximum strength characteristics with a high hardening coefficient at the stage of macrodeformation. At the same time, the plasticity is maintained at a level sufficient for technological purposes. Structural metallographic and electron microscopic studies showed that increase in strength of steel when rolling in embossed rolls under conditions of electroplastic effect is caused by the refinement of ferrite grains to sizes less than 0.5 µm. Fractographic studies revealed changes in the nature of fracture in steel during rolling in embossed rolls, which is expressed in appearance of areas of brittle fracture in the rolled samples. Rolling under conditions of electroplasticity increases the proportion of ductile fracture and ductility of 10G2FBYu steel.

Published: December 2023

The paper presents the results of studies of macro- and microstructure of alloyed chromium-vanadium cast iron after laser treatment (LT) in air using a continuous laser source with a variation in its power from 60 to 100 W and scanning speed of the laser beam varying from 5 to 17 mm/s. Metallography and durometry methods were used to determine composition and structure of the laser exposure zones (LEZ). It is shown that LT with a slight melting of the surface leads to a significant increase in microhardness in LEZ. In this case, martensite is the main structure in the near-surface layer of LEZ in the melting zone, and ledeburite structure prevails in the quenching zone. For the studied LT modes, LEZ depth is 220 – 310 μm. At the same time, microhardness is more than 2.5 – 4.2 times higher than microhardness of the base metal and reaches 820 HV0.1, that is a significant factor in increasing the wear resistance of the material. On the contrary, no significant structural changes were found in the case of LT without melting the surface. In order to identify the role of LT in wear of cast iron, sliding friction tests were carried out according to the “disk – finger” scheme at a pressure in the contact zone of 12.5 MPa and indenter rotation speed of 580 rpm. According to the test data, a significant decrease in linear wear and the wear intensity after the surface melting was found. The wear intensity is reduced by more than 100 times, and linear wear – by more than 50 times. The characteristics of LEZ surface cause a decrease in the friction coefficient by 30 % relative to the untreated surface.

Published: December 2023

Burnt pellets must retain their strength from the moment they are taken out of an induration machine until they are loaded into a blast furnace. One of the indicators of the burnt pellets’ strength is the compressive strength, i.e. the ultimate force. In experiments to determine compressive strength, the main type of fracture is occurrence and development of cracks that pass through the core center of pellets (where the maximum radial tensile stresses present) or near it. The paper presents the requirements for static compression strength imposed by blast furnace production to iron ore pellets. Using an optical and scanning electron microscope equipped with an energy-dispersive microanalyzer, we analyzed the relationship of structural components and pores in the core of burnt unfluxed iron ore titanomagnetite pellets with the ultimate force under static compression. By scanning electron microscopy and X-ray spectral microanalysis, it was established that the core of pellets is a multiphase material, and its main phases are titanomagnetite, magnetite, titanohematite, hematite and aluminosilicate binder. Optical microscopy made it possible to establish the microstructure of the pellet core, which has three types of microstructures: non-oxidized core (magnetite or titanomagnetite), partially oxidized core – around (magnetite or titanomagnetite) hematite grains (titanohematite) and oxidized core (hematite and titanohematite). The main factors for obtaining pellets with an ultimate force of more than 2.5 kN/pellet according to the requirements of blast furnace production are: the number of closed macropores and the number of large grains in the core. It is shown that with an increase in the number of closed macropores and the number of large grains in the core, the ultimate force is reduced from 3.5 kN to 0.87kN/pellet.
Interaction of cracks with grain boundaries in iron bicrystals

Published: December 2023

Molecular dynamic modelling of seed cracks evolution in iron bicrystals with inclined grain boundaries under uniaxial expansion was carried out. The process of seed crack evolution can be divided into four stages. At the first stage, in the interval of elastic deformations, the seed crack is stationary, and the stresses increase linearly, reaching a maximum value of ~7.0 GPa. At the same time, the atomic volume and stresses at the crack tip before its opening grow significantly faster than the average for the sample. At the second stage, the crack begins to spread into the grain volume. The process of crack propagation leads to an abrupt stress release due to relaxation processes in the areas adjacent to the crack banks and the emission of defects from the crack tip. After reaching the grain boundary, the crack stops and blunts. At the third stage, the crack remains in the grain boundary, and the sample stresses experience significant oscillations, which is caused by the emission of various defects both from the grain boundary and from other interfaces. The emission of defects from the crack tip can cause local migration of the grain boundary, which is formation of a bend on the initially flat surface of the grain boundary. When defects cease to be emitted from the crack tip, the voltage and atomic volume in this region increase rapidly. At the fourth stage, the crack begins to spread into the second grain. It was found that a boundary with a large grain misorientation angle is a more effective barrier restraining crack propagation. Initiation of the seed crack propagation in material is always preceded by an abrupt increase in atomic volume and stresses at the crack tip.

The features of phase transformations of 12 % chromium ferritic-martensitic steel EP-823 under heating and cooling conditions in the temperature range from 30 to 1100 ℃ were studied by the methods of high-temperature X-ray diffraction analysis (XRD) in situ and differential scanning calorimetry (DSC). According to XRD in situ data, upon heating, the temperatures of the beginning and end of the (α → γ) transformation of ferrite (martensite – austenite) are Ac1 ≈ 880 °C, Ac3 ≈ 1000 °C, respectively. Upon cooling, a diffusion (γ → α) transformation occurs with critical points – Аr1 ≈ 860°С (beginning temperature) and Аr3 ≈ 840 °С (end temperature). According to DSC data, during heating, the critical points of the (α → γ) transformation are Ac1 ≈ 840 °C and Ac3 ≈ 900 °C. During cooling, a martensitic (γ → α) transformation is realized with critical points of the beginning of Ms = 344 ℃ and the end of Mf = 212 ℃ of this transformation. The XRD in situ analysis revealed no precipitation of carbide phases under heating and cooling conditions of steel EP-823. Position of the critical points of phase transformations depends on the research method (XRD in situ or DSC), which is determined by the difference in effective (taking into account the time for shooting in the XRD method) heating-cooling rate. The effect of elemental composition on the position of critical points of phase transformations and the formation of structural-phase states of ferritic-martensitic steels is discussed. It is shown that the increased content of ferrite-stabilizing elements (Cr, Mo, Nb) in composition of EP-823 steel, compared with other steels of the same class, expands the region of existence of the ferrite phase, which can contribute to an increase in the temperature of Ac1 .

The paper presents the results of a laboratory study of the effect of refilling the ingot knock-off head with melt in a certain time interval after pouring the ingot body on solidification and structure formation of the model ingot. The research was carried out by the method of physical (cold) modeling for which a laboratory installation (casting form-mold) was developed and manufactured. It allows visually studying the processes occurring during solidification and structure formation on a 19.6-ton model ingot. We used sodium sulfuric acid (crystalline hyposulfite) as a modeling solution. Correspondence of the processes occurring on the model and in real conditions of industrial ingots casting was evaluated using similarity criteria obtained on the basis of dimension theory with analysis of physico-chemical processes occurring during casting and crystallization of the ingot. Casting of the melt into the casting form-mold was downhill. In order to assess changes in the temperature field during casting and crystallization of the ingot in the entire solidification time, we performed thermometry of the mold model surface. Analysis of the conducted studies results showed that refilling the melt before 40 min leads to stimulation of early settling of crystals (“rain of crystals”), which contributes to an increase in the crystallization directivity in vertical direction. It was established that in a conventional ingot up to 40 min solidification proceeds by a sequential mechanism, and after that the crystals begin to settle (“rain of crystals”) and the solidification of the ingot passes through a volume-sequential mechanism. Refilling the ingot knock-off head with melt 40 min after pouring the ingot body contributed to the continuation of the sequential mechanism of ingot solidification, which led to the formation of a monolithic defect-free structure in the ingot body and the least development of shrinkage shell in the knock-off head. The results obtained make it possible to develop a technology for differentiated ingots casting when filling their knock-off heads with melt in a certain time interval after pouring the ingot body, which will affect the process of metal structure formation and reduce defective zones.

Published: December 2023

The aim of this work was to study the influence of the iron and carbon doping of the epitaxial GaN layer on sapphire on the growth features of epitaxial films and their dislocation structure. Investigation methods used were: mass spectroscopy of secondary ions, selective chemical etching on spherical sections, and also single-crystal diffractometry.It is shown that doping during growth of an epitaxial GaN layer with carbon can lead to a significant decrease in the dislocation density in epitaxial layers.It has been shown that for samples doped with iron, a decrease in the number of short dislocations located in the bulk of the structure is characteristic, but a large number of extended dislocations are generated contributing to the diffusion of iron into the working regions of heterostructures, which can adverselyinfluence on the electrical parameters of the structures. In the course of the work, a technique for determining the density of dislocations in epitaxial films was proposed using two schemes of selective etching of spherical thin sections, which makes it possible to determine the dislocation density distribution over the depth of epitaxial films.

Published: December 2023

The Zn1-xNixO nanoparticles have been synthesized by novel co-precipitation method and systematically characterized by XRD, SEM, TEM and photo luminescence. The XRD patterns confirm the hexagonal wurzite structure without secondary phases in Ni substituted ZnO samples. SEM and TEM are used for the estimation of particle shape and size. In PL study there is a peak in the range of 380—390 nm in all samples that is attributed to the oxygen vacancies. Gas sensing tests reveal that Ni doped ZnO sensor has remarkably enhanced performance compared to pure ZnO detected at an optimum temperature 100 °C. It could detect ethanol gas in a wide concentration range with very high response, fast response–recovery time, good selectivity and stable repeatability. The possible sensing mechanism is discussed. The high response of ZnO Nanoparticles was attributed to large contacting surface area for electrons, oxygen, target gas molecule, and abundant channels for gas diffusion. The superior sensing features indicate the present Ni doped ZnO as a promising nanomaterial for gas sensors. The response time and recovery time of undoped is 75 s and 60 s and 0.25 at.% Ni are found to be 60 s and 45 s at 100 °C respectively.

Published: December 2023

The effects of changing the acceptors concentration on the electrical characteristics of Au/Ti on Be-doped Al0.29Ga0.71As Schottky contact have been investigated in the temperature range of 100—400 K. Using three devices with three different doping levels, the barrier height (ΦB), ideality factor (n) and series resistance (RS) for each diode were evaluated using both thermionic emission (TE) theory and Cheung's method. Our experimental results showed that the sample with a moderate doping concentration of 3 · 1016 cm-3 has the best performance, including ideality factor of 1.25 and rectification ratio of 2.24 · 103 at room temperature. All samples showed an abnormal behavior of reducing ΦB and increasing n with increase of temperature. This behavior was attributed, in case of low concentration samples, to barrier inhomogeneity and was explained by assuming a Gaussian distribution of barrier heights at the interface. While for the heavily doped sample, such non-ideal manner was ascribed with tunneling through the field emission (FE) mechanism.

As plantas ruderais são adaptadas aos ambientes antrópicos e contribuem com a biodiversidade, servindo como fonte medicinal, alimentar e ornamental ao homem. No paisagismo, as espécies ruderais podem acrescentar interesse visual ao espaço construído. De rápido crescimento, fácil cultivo e baixo custo elas são uma alternativa viável ao uso das plantas convencionais. Entretanto, para utilizá-las faz-se necessário o conhecimento de suas espécies e características. Dentro deste contexto e da meta “tornar as cidades e os assentamentos humanos inclusivos, seguros, resilientes e sustentáveis” dos Objetivos de Desenvolvimento Sustentável, este estudo teve como objetivo caracterizar a flora ruderal da Campina Experimental do Cerrado. As coletas de material reprodutivo foram realizadas semanalmente, de março a julho de 2023, e os espécimes foram identificadas até o nível de espécie, herborizados e incorporados ao acervo do Herbário UNBA. Elaborou-se uma lista florística com os nomes científicos, nomes populares e indicação da origem. A flora ruderal da Campina Experimental do Cerrado apresenta uma alta riqueza florística constituída por 59 espécies, de 42 gêneros e 20 famílias, com predominância das famílias Asteraceae, Poaceae e Cyperaceae e de espécies nativas. O próximo passo consiste na avaliação do potencial ornamental dessas espécies, para subsidiar o planejamento de novos jardins que podem ser parte da conservação do Cerrado em ambientes urbanos.

Study purpose. Although it is acknowledged that exercise can positively affect both physical and biochemical markers in older individuals with type 2 diabetes (T2DM), there are still uncertainties about the specific impacts of combining Thai yoga with an elastic band exercise in this population. The objective of the study was to assess the impact of a 12-week program involving Thai yoga combined with an elastic band exercise on the physical fitness and functional exercise capacity among older individuals with T2DM.
Materials and methods. A total of 42 participants, consisting of 20 men and 22 women with T2DM and a mean age of 64.6±3.6 years, were randomly assigned to two groups: the control group and the exercise group. The exercise group engaged in a daily regimen of Thai yoga combined with an elastic band exercise for 40 minutes, 5 days a week, over a 12-week period. In contrast, the control group maintained their regular routines. Physical fitness and functional exercise capacity were assessed both before and after the 12-week intervention.
Results. The exercise group showed significant reductions in body weight (58.7±11.9 vs. 58.0±12.0 kg), body mass index (24.2±3.0 vs. 23.9±3.0 kg/m2), waist circumference (33.6±3.6 vs. 33.1±3.6 in), and waist-hip ratio (0.90±0.06 vs. 0.89±0.06) (p < 0.001). Additionally, there were notable improvements in physical fitness parameters, including hand grips, back strength, leg strength (p < 0.01), and trunk flexibility (p < 0.001). Functional exercise capacity, indicated by the 6-minute walk test and estimated peak oxygen consumption (p < 0.01), also improved significantly.
Conclusions. Thai yoga combined with an elastic band exercise enhances physical fitness and functional exercise capacity in older individuals with T2DM. This improvement has the potential to enhance their cardiopulmonary performance. Consequently, this exercise regimen is considered a health alternative for older individuals with T2DM.

Background. Somatotyping in modern sports can be an important factor to be considered. Different studies have already taken the initial step to identify the sport-specific somatotypes for different games and sports. In contrast with the Kho-Kho game, some attempts have been made to identify somatotypes specific for these games. But there are only few studies that have been conducted, and various areas are still waiting to be explored.
Study purpose. The present study aimed to identify the specific somatotypes of the kho-kho players. Additionally, this study also made an attempt to explore the important somatic traits that influence the somatotypes of the Kho-Kho players.
Materials and methods. A total number of 74 players from six Kho-Kho teams that participated in East Zone Inter-University Tournament were purposively selected for the study. The anthropometric data collection was done according to the standard procedures given by ISAK (International Society for Advancement of Kinanthropometry). The statistical analysis was done by using MS Excel (2021) and SPSS’23.
Results. The results of the study showed that most of the Kho-Kho players (90.6%) were possessing ectomorphic and mesomorphic dominant traits. There was also a significant difference found in ectomorphic and mesomorphic traits among the players possessing mesomorphic-ectomorph (p<0.05), ectomorphic-mesomorph (p<0.05) and ectomorph-mesomorph (p<0.05) somatotypes. Furthermore, the discriminant analysis also highlighted that attributes of ectomorphic traits (Discriminant coefficient = 1.168) and mesomorphic traits (Discriminant coefficient = 0.812) were important somatic traits for the Kho-Kho players. Overall, 88.6% of the original cases have been correctly represented by the discriminant analysis.
Conclusions. The present study showed that Kho-Kho players for the most part possess the ectomorphic and mesomorphic dominant somatotypes. Furthermore, based on the study results, it can be also concluded that somatic attributes in the similar body types also play important role to determine players’ performance level.

Published: December 2023

In today’s economy based on knowledge and innovation, the development of absorptive capacity by companies is a critical aspect of business competitiveness. In this study, the tech stack of sites is considered as a specific, measurable part of the digital and innovative development of a company. In literature to date, there is no clear answer to which technologies and in what quantity should be included in the tech stack. From the point of view of assessing the tech stack, mainly qualitative methods are proposed that are quite resource intensive. Accordingly, the purpose of this study is to determine the impact of the technologies used by the characteristics of quantity, uniqueness and popularity in the tech stack of the product on the result (the absence of critical errors); as well as in developing a quantitative approach for assessing the impact of the technologies used on the result of a digital product. The quantitative approach was developed and conceptualized based on previous literature, tested on 12 sites of large Russian banks, including 12 main domains and 595 subdomains. An analysis of a study of 216 online applications for banking products showed a positive relationship between the share of unique technologies in the bank’s visible tech stack and the number of errors, as well as a negative relationship between the share of popular technologies in the stack and errors. This study expands the discussion on the development of absorptive capacity, contributes to the understanding of the limitations of absorptive capacity of companies and proposes a quantitative approach for auditing the operational tech stack of companies’ websites.

Bu çalışma genellikle apolitik olarak adlandırılan, bireysel değişimi, gelişimi ve tekâmülü hedefleyen spiritüel hareketler ile siyaset arasında duygular sosyolojisinin kavramsal imkânlarını kullanarak bir ilişki kurmaya çalışıyor. Spiritüel hareketlerin spiritüel nitelikleri yanında büyük oranda duygulara hitap ettiğini; bir tür duygu siyaseti yürüttüklerini ve alternatif bir duygusal kamusal alan inşa etmeye çalıştıklarını iddia ediyor ve bu iddiasını 2018 ve 2020 yılları arasında yaptığımız bir alan araştırmasının verilerinden yararlanarak temellendirmeye çalışıyor. Bunun için öncelikle duygu siyaseti ile neyi kastettiğimizi, ardından da spiritüel hareketleri neden bu kapsamda değerlendirdiğimizi anlatmaya çalışacağız. Böylece hem duygular sosyolojisi hem de spiritüel hareketler literatürüne katkı sunmayı amaçlıyoruz. Bu kapsamda öncelikle duygu, duygulanım, kamusal duygular ve duygu siyaseti gibi kavramları, bu kavramların içinden çıktığı duygular sosyolojisi alanı çerçevesinde ele alıp spiritüellik, duygular ve siyaset arasındaki ilişkileri tartışacak; ardından da bu tartışmaları birbiriyle bağlayıp alan bulgularıyla birleştirmeye çalışacağız. Makale, ulaştığımız sonuçların genel bir değerlendirmesi ile son bulacak.

Published: December 2023

Bu makale spiritüel eğilimlerden hepsine değil; bunlardan biri olan astrolojiye odaklanmaktadır. Ancak bu odak noktasında, astrolojinin ne olduğunun önemi bulunmamaktadır. Astrolojinin gündelik hayat içindeki deneyimlenme biçimi, astrolojiye yönelişin sebepleri, bireylerin astroloji uygulamaları ile ne yaptığı mercek altına alınmaktadır. Özellikle dijital çağ ile spiritüellik de kendine dijital bir form oluşturmaya başlamıştır. Spiritüel pratiklerden biri olan astroloji de tarih boyunca olduğu gibi, günümüzde de oldukça popülerdir. İnsanlar astrolojiye sadece merak, eğlence gibi nedenlerle yönelebildiği gibi, belirsizliklerden, korkudan veya inançtan dolayı da yönelebilmektedir. Bireylerin astrolojiye olan ilgilerine yönelik çeşitli araştırmaların aksine, dijital spiritüel uygulamaların deneyimlenme şekillerine yönelik yapılan araştırmalar kısıtlıdır. Bu çalışma, bir astroloji uygulaması olan, Co-Star’ı kullanan kişilerin deneyimlerine odaklanan nitel bir araştırımadır. Yarı yapılandırılmış sorularla mülakat yapılan katılımcılar, 25-35 yaş arasında ve çoğunlukla kadın bireylerden oluşmaktadır. Araştırmanın analizi sonucunda, katılımcıların uygulama deneyimleme biçimleri belirli temalar çerçevesinde değerlendirilmiştir.
