The Soil is Alive: Cultivating Human Presence Towards the Ground Below Our Feet
Authors: LeVasseur Todd
Published: June 2024

This article invites readers to rethink the presence and role of soil by creating a soliumpoietics, without which terrestrial plant life itself struggles to occur. It utilizes both materialism/material agency and hyperobject lenses to analyze soil. In so doing it argues that these lenses may provide a more holistic understanding to better theorize soil as an agential and interobjective other, without which civilization would most likely rapidly collapse. It undertakes this exploration within the context of rapid climate change and global heating, which threatens the survival of many soils (and thus plants), too. These alarming scenarios have severe implications for the academy, broadly, which the article argues scholars must attend to within their teaching and researching, including new research regimes on plant-based caloric lifeways, especially where such lifeways are regenerative to soil, plants, and thus, the human.

Published: June 2024

Recently, the level of criminals and terrorists using light weapons (such as knives and firearms) has increased rapidly around the world. Unfortunately, most current surveillance systems are still based mainly on human monitoring and intervention. For that reason, the requirement for a smart system for detecting different weapons becomes crucial in the field of security and computer vision. In this article, a novel technique for detecting various types of weapons has been proposed. This system is based mainly on deep learning techniques, namely, You Only Look Once, version 8 (YOLOv8), to detect a different class of light weapons. Furthermore, this study focuses on detecting two armed human poses based on ensemble learning techniques, which involve combining the outputs of different Yolov8 models to produce an accurate and robust detection system. The proposed system is evaluated on the self-created weapons dataset comprising thousands of images of different classes of weapons. The experiment results of this work show the effectiveness of ensemble learning for detecting various weapons with high accuracy, achieving 97.2% of mean average precision.
Study on the current situation and influencing factors of corn import trade in China – based on the trade gravity model
Authors: He Hongxue
Published: June 2024

With the rapid development of China’s economy and society, the income level of Chinese residents is increasing day by day, and the dietary consumption structure of domestic residents is constantly optimized and upgraded. The consumption demand for livestock products such as meat, eggs and milk, and corn starch industrial products is increasing day by day. Therefore, as the main raw material of feed industry and deep processing owners, the consumption scale of China corn market is constantly expanding. However, the corresponding domestic corn production scale has not expanded, and the domestic corn production presents an obvious problem of insufficient supply scale, which leads to a sharp and rapid increase in the number of corn imports in China, which seriously impacts the domestic corn market and affects China’s healthy development of corn industry. In recent years, the continuous spread of the COVID-19 epidemic has seriously affected the global grain production and trade. The fierce military conflict between Russia and Ukraine, the two major grain exporting countries, has once again brought a serious adverse impact on the supply and price of the global grain market, resulting in an increase in the import cost of corn in China and a change in the import pattern of corn in China. In this regard, this study analyzes the current situation of corn production and import trade in China, and based on the relevant trade data between China and major corn importing countries from 2013 to 2022, establishes a trade gravity model to quantitatively evaluate the main factors affecting China’s corn import trade, and analyzes the trade potential of sample countries. It was found that in 2022, China’s import and export trade volume and trade value were 20.62 million tons and 7.11 billion US dollars, respectively, compared with 2013, trade volume and trade volume increased by 6.3 times. Statistics on the potential types of various trading countries showed that the proportion of potential countries was 14.2%, and Brazil had the greatest potential in China’s corn import trade. The proportion of potential expanding countries is about 71.4%, and Laos is a mature country with less opportunities for further development. In order to promote the benign development of the domestic corn industry and the development of China’s corn import trade, this paper puts forward a series of countermeasure suggestions based on the above research.
Zwischen Abhängigkeit und der Möglichkeit einer Kooperation: Beherbergungsbetriebe und ihre Strategien im Umgang mit Onlinebuchungsplattformen
Authors: Balk Anselm
Published: June 2024

Der Artikel behandelt mittels quantitativer Forschungsmethoden die Frage, wie Unternehmen in Branchen, in denen Onlineplattformen eine wesentliche Rolle im Wertschöpfungsprozess spielen, mit der sich daraus ergebenden Situation umgehen. Exemplarisch wird die Situation anhand von Beherbergungsbetrieben in Niederösterreich betrachtet. Dabei ist festzustellen, dass die Betriebe die Dienstleistungen der Onlinebuchungsplattformen (OTAs) mehrheitlich nutzen und wertschätzen. Allerdings sehen sie sich ihnen gegenüber in einem Abhängigkeitsverhältnis. Dies führt dazu, dass sie u.a. Provisionen akzeptieren, die als zu hoch wahrgenommen werden. Um dieses Abhängigkeitsverhältnis zu reduzieren, wird untersucht, ob und welche Lösungswege Betriebe sehen, um dies zu erreichen. Ein besonderer Fokus liegt hier auf gegenseitigen Kooperationsmöglichkeiten. Dabei ist festzustellen, dass die Mehrheit der Betriebe einer Zusammenarbeit positiv gegenübersteht. Maßnahmen, die darauf abzielen, Abhängigkeiten gegenüber OTAs zu reduzieren, indem ein Gegengewicht aufgebaut wird, werden jedoch skeptisch gesehen. Kommt es jedoch zu einer Kooperation, die zu einer indirekten Stärkung führt, sehen die Betriebe großes Potential. Hier können u.a. genossenschaftliche Ansätze beitragen. So untersucht der Artikel praxisgeleitete Möglichkeiten von Kooperationen und richtet sich neben einer akademischen Leserinnenschaft auch und insbesondere an Personen aus der Praxis.

Published: June 2024

The textile industry contributes significantly to environmental pollution through the discharge of non-biodegradable colored dye effluents, emphasizing the need for effective wastewater treatment methods. Traditional approaches, including physical and biological treatments, face limitations, necessitating exploration into advanced oxidation processes (AOPs). Iron-based photocatalysts, particularly those synthesized through green methods, have shown promise in degrading organic pollutants. In this study, iron nanocomposites, including CSINCs, ASINCs, and ACINCs, are synthesized by mixing two different plant extract mixtures with an Iron precursor solution. XRD analysis confirms cubic structures for the prepared nanocomposites, with crystalline sizes of 14.21, 15.79, and 28.74 nm, respectively. UV–vis spectrophotometer shows characteristic absorption peaks in the 380–400 nm range. FESEM imaging reveals spherical particles, and EDX analysis detects typical signals of Fe, O, and C. FTIR spectra indicate various functional groups present in the nanocomposites. The study further focuses on optimizing the degradation of Reactive Blue 171 (RB 171) dye, considering factors such as pH, concentration of RB 171, and photocatalyst concentration. The results demonstrate that ACINCs, specifically at a concentration of 10 mg/100 mL in a mixture with Reactive Blue dye at a concentration of 50 ppm, exhibit enhanced degradation under UV irradiation. This detailed investigation contributes to the understanding of the structural and functional characteristics of Iron nanocomposites and their potential application in the efficient degradation of textile dyes, emphasizing the importance of optimizing key parameters for enhanced photocatalytic performance.

Authors: Ong Yean Sze , Abdul Rahim Noor Fareen , Md. Hanifah Haniruzila
Published: June 2024

In the context of Malaysian research universities, this study examined how psychological ownership influenced Malaysian academics’ intention to stay. Based on self-determination theory, a model was developed to investigate how psychological ownership and employee engagement might improve the intention to stay. A questionnaire survey was used to gather the data, which was then analyzed using partial least squares structural equation modeling (PLS-SEM). The results show that psychological ownership positively and significantly impacts employee engagement. The intention of an employee to stay is also positive and significantly impacted by employee engagement. In addition, when employing employee engagement as a mediator, psychological ownership also revealed a significant indirect effect on the intention to stay. The novelty of this study contributed to the body of knowledge on psychological ownership and intention to stay while also shedding light on the mediation of employee engagement in the context of Malaysian research universities. The findings of this study also have significant practical implications for academics and policymakers who wish to understand the roles of psychological ownership and employee engagement that contribute to the intention to stay among academics.

Systematics and distribution of the genus Darevskia Arribas, 1997 on the Iranian plateau: a review
Authors: Rastegar-Pouyani Nasrullah , Yusefi Milad , Karamiani Rasoul
Published: June 2024

Two hundred ninety species of lacertids are presently placed in from 24 to about 30 genera. Most of the genera that have been recognized appear to be clades on the basis of their morphology, with the exception of the paraphyletic central African Adolfus and Lacerta sensu lato of Europe, Asia and northwest Africa. Traditionally, species boundaries are only based on morphological and appearance differences, and this approach is qualitatively or quantitatively investigated. At the same time, several new and modern methods can be used for a more realistic and logical investigation in the determination of species boundaries. Molecular analysis has provided more evidence about lacertids' kinship relationships. These methods work particularly well when dealing with cryptic species or species complexes. Where there is a high general and morphological similarity between the species of a population. The rock lizards, genus Darevskia Arribas, 1999, are such species, as many of its members have few distinctive and diagnostic morphological features. Biodiversity and species diversity assessment allows for more precise determination of the causes of many biological processes. These processes involve complex patterns that are especially observed in areas with high species diversity. Anatolia and Caucasus regions are two important geographical regions where Darevskia species live, which have complex morphology and unique speciation. Darevskia valentini and D. rudis are two widely distributed species of this genus, both of which have controversial taxonomy. In this study, an attempt has been made to summarize the species available in Iran.

Published: June 2024

Background: This audit aimed to evaluate and measure the outcomes of spermatogenesis induction over a 5-year period. Men with primary, as well as central hypogonadism, received gonadotrophin therapy to stimulate sperm production and fertility outcomes, including live birth rates. Predictors associated with live births, were measured retrospectively. Methods: Men with severe oligospermia (sperm concentration <5million/ml), having gonadotrophin prescriptions for a minimum of 6 months, were identified via the electronic prescription system. They were asked to complete a service evaluation questionnaire. Results: Men with persistent azoospermia were more likely to have a diagnosis of PH (Odds ratio 22.5, p<0.001) and smaller testicular size (Odds ratio 8.8, p<0.001), compared to men with successful spermatogenesis. Twenty-eight per cent (13/47) had partners, who conceived spontaneously and delivered healthy babies. Nine per cent (4/47) had a live birth after ART. Live birth rate was higher in men with CH compared to PH, with 17 of 45 (38%) men with CH having a partner that successfully delivered a baby. Conclusion: Men with mainly central hypogonadism and female partners with no known subfertility are most likely to achieve conception and live birth. Patient education on the results of semen analysis or female factors affecting fertility could improve overall outcomes.

Dimensi Maqashidiyah Kisah Kaum Sodom dalam Al-Qur'an Surat Al-A'raf Ayat 80-81
Authors: Mujaddi Lalu Riastata Al , Ashri Zainul
Published: June 2024

Stories in the Qur'an have various interpretations and dominantly tend to tell stories like storytelling in general. This happens because of the method and intellectual background of the mufasir. Despite this, story verses in the Qur'an have a fairly important position and even the Qur'an is dominated by story verses. This indicates that a more in-depth study of the verses of stories in the Qur'an is needed so that the purpose, maqashid or maghza of the verse can be understood and the lessons (‘ibrah) from the previous story are applied to the present day. Therefore, this paper will try to reveal the deepest message of the homosexual story in Qs. al-A'raf [7]: 80-81 with the method of tafsir maqashidi by Abdul Mustaqim. With a library research, descriptive-analysis and tafsir maqashidi method, this paper produces findings: after conducting a fairly in-depth analysis of the story of sodomy in Qs. Al-A'raf [7]: 80-81, the main message contained in the verse is for hifzh an-Nafs or self-preservation as a foothold for improving social order as well as hifzh ad-Daulah, so that the surrounding community does not fall into homosexuality like the previous Sodomites which caused the descent of Allah's punishment which can damage the natural environment or bring natural disasters.

Authors: Öztay Çağan Hilal , Şüküroğlu Veysel Karani
Published: June 2024

İşletmelerin yoğun rekabet ortamlarında varlıklarını sürdürmeleri için tüketicilerin davranış kalıplarını iyi analiz etmesi gerekmektedir. Seçenek sayısının fazla olması tüketiciler için bir avantaj olarak görülmekteyken bu durum işletmeler için dezavantajlı bir durum oluşturmaktadır. Bu yüzden pazarlama yöneticileri tüketicilerin çeşitli satın alma davranışlarının öncüllerinin belirlenmesine önem vermektedir. Ürünlerin kıt olduğu durumlarda tüketicilerin nasıl tepki verdiğinin belirlenmesi de bu kapsamda önemli bir konudur. Ayrıca plansız satın alma da günümüz tüketicisinin sıklıkla uyguladığı bir satın alma şeklidir. Mevcut gerçeklerden hareketle bu çalışmanın amacı algılanan kıtlığın tüketicilerin plansız satın alma davranışlarına olası etkilerinin araştırılmasıdır. Materyalizm ve moda liderliği özellikle beğenmeli ürün kategorisindeki ürünlere yönelik tüketici tepkilerinin belirlenmesi açısından önemli kavramlardır. Bu yüzden materyalizm ve moda liderliğinin de algılanan kıtlık ile plansız satın alma davranışı arasındaki ilişkide düzenleyici bir etkiye sahip olup olmadığı araştırılmıştır. Çalışma hipotez test etmeye dayalı olarak yürütüldüğü için niceliksel araştırma yaklaşımı benimsenmiş ve anket tekniği ile 348 katılımcıdan veri toplanmıştır. Betimsel analizler ve hipotez test tekniklerinden yararlanılarak veriler analiz edilmiştir. Araştırma sonuçlarına göre algılanan kıtlığın plansız satın alımlarda etkili olduğu, başarı odaklı materyalizm, sahiplik odaklı materyalizm ve moda liderliğinin de algılanan kıtlık ve plansız satın alma davranışı ilişkisinde düzenleyici rolü olduğu ortaya konmuştur. Düzenleyici etki değişkenlerinin düşük ya da yüksek olduğu durumlardaki değişimin ortaya konması için de slope (eğim) analizi uygulanmıştır. Sonuçlara göre başarı odaklı materyalizm, sahiplik odaklı materyalizm ve moda liderliği düzeyi düşük olan tüketicilerde algılanan kıtlığın plansız satın almalara neden olmadığı, düzenleyici etki değişkenlerinin düzeyi yüksek olan tüketicilerde ise kıtlık algısının plansız satın almalara neden olduğu ortaya konmuştur. Çalışma sonuçları düzenleyici etki değişkenlerinin önemini ortaya koymaktadır.

Authors: Gromov V. E. , Konovalov S. V. , Efimov M. O. , Panchenko I. A. , Shlyarov V. V.
Published: June 2024

Created one of the first and studied more than 20 years ago, high-entropy five-component alloys CoCrFeNiMn (Cantor alloy) and CoCrFeNiAl still attract the attention of researchers in the field of physical materials science due to their possible application in various industries because of their successful combination of strength and plastic properties. To date, a large amount of experimental materials has been accumulated on the ways to control the properties of these alloys. This article reviews the publications of domestic and foreign authors in two areas of improving the properties of these alloys: alloying, precipitation and heat treatment, and the use of CALPHAD phase diagrams. In the first direction, the role of alloying with B, Al, V, Si, Nb is analyzed; γ and γ′ nanoprecipitations, various modes of thermal and deformation processing. It was concluded that it is necessary to conduct experiments on the alloying of HEAs with Zr and Nb, which have proven themselves well in hardening steels. Creation and modification of the properties of five-component HEAs is possible using the CALPHAD computer programs developed for calculating state diagrams. The results of publications on the thermodynamic description of five-component alloys analyzed in the article are confirmed by comparing the phase diagrams with the available experimental data. In one of the analyzed works on the phase formation of five-component HEAs consisting of Co, Cr, Fe, Ni, Al, Mn, Cu, 2436 compositions were considered, which made it possible to determine 1761 variants of reliab­le prediction of the formation of bcc/B2 and fcc phases, bypassing amorphous phases and intermetallic compounds, thereby designing a certain level of mechanical properties. It is shown that the design of a new generation of HEAs is possible based on calculation of the CALPHAD phase diagrams.

Published: June 2024

This paper presents results of the studies of hydrogen exposure duration influence on the characteristics of two aviation alloys at atmospheric pressure and room temperature. First alloy (alloy 1) was obtained by hot isostatic pressing, and was used for the manufacture of gas turbine rotor discs. Second alloy (alloy 2) was obtained by directional crystallization, and was used for the manufacture of gas turbine blades. It was determined that microhardness of the samples increased during 1000 h of hydrogen exposure duration. The relative increase of the microhardness was insignificant, and for the sample of alloy 1 it was 2.5 %, and for the sample of alloy 2 – 2 %. Correlation analysis of the XRD diagram parameters indicated positive and negative statistically significant relationships correlation between XRD diagrams peaks parameters, hydrogen exposure duration and microhardness of the samples. It was revealed that XRD diagrams peaks of alloy 1 were broadened and their heights increased during hydrogenation, which can be associated with a decrease of dislocations in the grains and their local accumulation at the grains boundaries. Conterwise, XRD diagrams peaks of alloy 2 were narrowed, which can indicate an increase of dislocations in the material grain structure. XRD diagrams processing demonstrated that the crystallite size and dislocation density for alloy 1 decreased with a delay from the hydrogenation start, but for alloy 2 these parameters monotonically increased, and it corresponds to microhardness changes trends of the samples during hydrogenation.

A téma megjelenése Márton Ferencnek a Vasárnapi Újságban megjelent Régi váraink ügyében című írásához köthető, melyben a szerző javaslatot tett archeológiai társulatok felállítására a vármegyékben az Akadémia támogatásával, de sürgette a magán-, családi, városi és egyházi levéltárak felmérés, módszeres kutatását, a fellelt okmányok hiteles másolatainak elkészítését és összegyűjtését. A munkálatok eredményeiről neves tudósok közöltek ismeretterjesztő cikkeket. Tanulmányomban a család- és helytörténészként is ismert Nagy Iván nógrádi vonatkozású írásait vizsgálom, melyek a tudományos esszé és a népszerű ismeretterjesztés jegyeit viselik magukon, illetve a lap főszerkesztőjével való levelezéséből idézek olyan részleteket, melyek a lapszerkesztés folyamatára is rávilágítanak.
Egyházellenesség a katolicizmus fővárosában
Authors: Molnár Dávid
Published: June 2024

Az első világháború kitörése előtti években Egerben is megerősödött a szociáldemokrata munkásmozgalom. A baloldali szerveződésnek egyedi jelleget adott, hogy a hagyományosan katolikus többségű és sajátos társadalmi-gazdasági berendezkedéssel bíró érseki székhelyen a helyi kulturális és művelődési viszonyokra a katolikus egyház volt leginkább hatással. A progresszív szemléletű egri szocialisták és a konzervatív klérus között ennek köszönhetően éles ellentét alakult ki. A szocialista mozgalom befolyásának ellensúlyozására az egyház keresztényszocialista egyesületek alapítását támogatta, de a két irányzat közötti ideológiai ellentét az egész dualizmuskori lokális sajtóban végigkövethető.Az 1910-ben induló és csak néhány hónapon át megjelenő Egri Munkás című lapból a helyi szociáldemokrata munkásmozgalom egyházellenes kritikája is jól megismerhető. Az alapvető eszmei különbségeken túl azonban az itt közreadott írások konkrét konfliktusokról is beszámolnak, melyek nagy mértékben meghatározták a 20. század első évtizedeinek egri közéletét. Előadásomban a legfontosabb témába vágó cikkek szemlézésén túl igyekszem azokat az országos szociáldemokrata sajtóban megjelenő antiklerikális írásokkal összehasonlítani, és ezáltal rávilágítani a dualizmuskori magyar munkásmozgalom komplex jellegére.

The research focuses on the analysis of open data on public procurement of innovative products and on procurement of research and development services (R&D). The principle of stimulating innovations is enshrined in the legislation governing public procurement. However, the complexity of testing products for innovation criteria, the differences in classifying products as innovative and the specifics of conceptual and categorical framework in this sphere indicate the peculiarities of the implementation of the principle of stimulating innovation by contracting authorities regulated by 44-FL and by 223-FL. This research empirically answers the following questions: What procured products in the market are considered innovative by contracting authorities? What characteristics and peculiarities are specific to innovative public procurement in Russia? What types and categories of contracting authorities perform such procurement? We reveal that the procurement of innovations is related to the law under which the organization conducts purchases, as well as to the organizational and legal form of the contracting authority. The procurement of innovations is also influenced by the method of determining the supplier, the price of the product and the subject of the purchase. The results of the study show heterogeneity in the procurement of innovations by Russian contracting authorities and link this heterogeneity with the differences in the procurement legislation.
IMPLEMENTING A RISK-BASED APPROACH IN LABOUR CONTROL AND SUPERVISION ACTIVITIES
Authors:   Russian Presidential Academy of National Economy and Public Administration, Savina Alexandra , Antonenko Natalia ,   Russian Presidential Academy of National Economy and Public Administration
Published: June 2024

Federal Service for Labour and Employment (Rostrud) adopted risk-based regulation and enforcement principles by installing a system of inspections targeted according to the object’s risk profile. However, the criteria that are used to evaluate the object’ risk ranking and to assign risk categories have not been revised since 2017. The purpose of this study is to analyze the Rostrud inspection prioritization system in 2017-2023, identify its weaknesses and evaluate how external factors (two periods of inspection moratoria, introduction of prophylactics measures) affected the results of inspection activity. Statistical analysis based on data obtained from Rostrud, Federal State Statistics Service, SPARK-Interfax, Unified register of control (supervisory) measures and Unified register of inspections, demonstrates that companies have been moved from one risk group to another intensively during 2017-2023 (about 15% of them have changed the risk category drastically during only one year of observation). It also has revealed the number of shortcomings in Rosrtud risk evaluation methodology that led to estimation bias and miscategorization of supervised organizations. At the same time, the connection between both prophylactics and inspection prioritization and risk category is weak, while their results have little influence on risk category revision. The study resulted in recommendations about ways the risk categorization methodology can be improved with minimal additional costs.

As políticas educacionais desempenham um papel vital ao fornecer diretrizes e recursos para a formação intercultural dos docentes. A colaboração entre professores, administradores escolares, pais e a comunidade é essencial para criar um ambiente de aprendizagem inclusivo e culturalmente sensível. Conclui-se que, para promover uma educação mais justa e equitativa, é necessário um compromisso contínuo com a formação intercultural dos professores, o desenvolvimento de políticas educacionais robustas e a utilização eficaz de tecnologias educacionais. Este estudo contribui para o campo das ciências da educação ao oferecer informações detalhadas sobre como aprimorar a formação docente e as práticas pedagógicas para melhor atender às necessidades de uma população estudantil diversificada.
Human RA-gastruloid induction from pluripotent stem cells v1
Authors: Hamazaki Nobuhiko
Published: June 2024

Gastruloids are a powerful in vitro model of early human development. However, although elongated and composed of all three germ layers, human gastruloids do not morphologically resemble post-implantation human embryos. Here we show an early pulse of retinoic acid (RA), together with Matrigel, robustly induces human gastruloids with posterior embryo-like morphological structures, including a neural tube flanked by segmented somites, and diverse cell types including neural crest, neural progenitors, renal progenitors, and myocytes. Through in silico staging based on single-cell RNA-seq (scRNA-seq), we find human RA-gastruloids to be more advanced than other embryo models, and comparable to E9.5 mouse and CS11 cynomolgus monkey embryos. We leverage chemical and genetic perturbations of RA-gastruloids to confirm that WNT and BMP signalling regulate somite formation and neural tube length in the human context, while transcription factors TBX6 and PAX3 underpin presomitic mesoderm and neural crest, respectively. Looking forward, RA-gastruloids are a robust, scalable model for decoding early human embryogenesis.

Androcentrism in Arabic Educational Materials: A Linguistic Analysis of GCC Countries’ Selected School Textbooks
Authors: Zumor Abdulwahid Q. Al
Published: June 2024

This study seeks to investigate the existence of androcentrism in school textbooks used in the six Gulf Cooperation Council (GCC) countries. It attempts to unveil potential implicit biases ingrained in the language of these textbooks. The data for this study is derived from a corpus comprising six textbooks, encompassing a variety of courses representing the GCC secondary level education systems. The employed methodological approach entailed content analysis, wherein categories were discerned directly from the textual data during a comprehensive examination of the textbooks. The established framework facilitated the classification of gendered linguistic references into three distinct categories: nouns, verbs, and pronouns. The principal findings highlight preferential representation of male students and, consequently, underrepresentation of female students, permeating almost the entire research corpus. Contrary to assumptions suggesting an intrinsic gender bias within the Arabic language, this investigation argues that the locus of androcentrism seems to be rooted in the authors of the scrutinized textbooks. This discernment contributes valuable insights challenging prevailing notions and accentuates the role of textbook authors in shaping linguistic biases.
