Personality Traits and Common Ingroup Identity: Support for Refugee Policies Among Host Members
Authors: Çoksan Sami , Kekeli Burak , Turgut Buse , Sağdış Elif
Published: October 2024

Türkiye, which has hosted the largest number of refugees in recent years, requires remedial intervention programs to facilitate adaptation and coexistence. The irony of harmony studies that guide these interventions seem incomplete due to limited sample characteristics and a lack of attention to personality traits. Hence, we aimed to explore relationships between personality traits, identification with common ingroup identity, and support for social policies toward refugees by sampling the advantaged majority and the disadvantaged largest minority in Türkiye across two correlational studies (Ntotal = 772). In Study 1, agreeableness, extraversion, openness, narcissism, and psychopathy were associated with support for positive social policies. On the other hand, neuroticism was linked with support for negative social policies. However, when identification with common ingroup identity was included in the model, the significance of personality traits in almost all models disappeared, indicating that only the prediction of identification with common ingroup identity remained. The findings of Study 2 replicated and extended the previous result by sampling disadvantaged group members. We suggest that it may be more effective to focus on intergroup variables rather than personality traits to strengthen support for refugee policies, as the overall findings pointed out.

Published: October 2024

Reactive oxygen species are produced by aerobic organisms, including humans, because of metabolism. They can oxidise biomolecules and cause degenerative and cardiovascular diseases (diabetes, atherosclerosis, and neurological damage, among others). However, the consumption of different plant products is related to the prevention of reactive oxygen species–mediated damage because they contain various antioxidants that inhibit the oxidation of biomolecules. Some important natural antioxidants are carotenoids, flavonoids, polyphenols, and vitamins. These molecules are found in various crops produced in Mexico, some of which have been cultivated for a long time, while others have emerged in recent years. The study of the antioxidant capacity of these crops has increased over time. Different methods are used to determine this capacity, depending on the type of antioxidants. In this review, we analyse the antioxidant quantification methods of various crops of interest in Mexico (traditional and emergent), as well as their relationship to prevent the oxidation of biomolecules.

Published: October 2024

Glioma is one of the most prevalent primary intracranial tumors, and biomarker testing offers a non-invasive modality with high diagnostic efficiency. The aim of this meta-analysis is to evaluate the diagnostic effectiveness of exosomes as biomarkers for glioma. We included 16 studies on exosomes as biomarkers for gliomas. The pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the curve (AUC) for 25 biomarkers across these 16 studies were as follows: 82% (95% CI: 0.77-0.86), 91% (95% CI: 0.86-0.94), 9.10 (95% CI: 5.64-14.68), 0.20 (95% CI: 0.16-0.25), 45.94 (95% CI: 25.40-83.09), and 0.92 (95% CI: 0.89-0.94), respectively. Meta-regression indicated that biomarker analysis, biomarker type, and sample size may be sources of heterogeneity. Subgroup analysis suggested that ultracentrifugation (UC) was a better method for extracting exosomes. miRNA and other RNA groups (sncRNA, lncRNA, circRNA) provided higher SEN (0.88 vs. 0.84 vs. 0.78) compared to proteins. This study demonstrates the superior diagnostic efficacy of exosomes as biomarkers for gliomas, with high accuracy in diagnosing gliomas.

At present, the task of ensuring high-quality control of unmanned aerial vehicles and the transmission of reliable information in a complex interference environment is relevant. This task becomes especially important when intentional interference is used in the form of countermeasures. Various methods are used to detect and localize powerful sources of parasitic signals, including: time domain methods: signal spectrum analysis, correlation function analysis, phase shift analysis; frequency domain methods: signal amplitude response analysis, signal phase response analysis, power spectral density analysis; spatial domain methods: antenna directivity analysis, signal strength analysis at different points in space. Analyzing signals affected by EW and artificial interference is a challenging task. Traditional signal analysis methods are often ineffective for this task because they cannot take into account the complex characteristics of EW and artificial interference. Neural network classifiers are a promising tool for analyzing signals with EW and artificial interference. Neural networks can learn from large datasets and detect complex patterns that cannot be detected by traditional methods. This article describes the process of selecting a neural network classifier for analyzing EW and artificial interference signals. Various factors that should be considered when choosing a neural network architecture, training algorithm, and network parameters are discussed). The paper presents an analytical review of neural network classifiers, their varieties and features, and selects the optimal one for solving the task.
UKRAINIAN-BRITISH RELATIONS AFTER BREXIT: BILATERAL COOPERATION AND EUROPEAN INTEGRATION OF UKRAINE
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Yakovenko Natalya , Luzan Yevhen ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: October 2024

The article examines the development of relations between Ukraine and the United Kingdom after the latter's withdrawal from the European Union. Expert assessments of the consequences of Brexit on Ukrainian-British relations, as well as the analysis of joint documents signed between Ukraine and the United Kingdom in the post-Brexit period, are taken into account. It turns out that, despite the decision to leave the integration association and its influence on political processes within the European community (loss of contributions to the common budget, lack of state representatives in key European institutions, strengthening of Eurosceptic tendencies in the rest of the EU member states), the United Kingdom remained an important international partner of Ukraine in bilateral relations and did not change its favorable attitude to Ukraine's European integration, guided primarily by foreign policy and security interests, but has lost access within the EU to levers of influence on positive decisions regarding Ukraine in this direction. The strategic level of partnership is laid down in the Trade and Cooperation Agreement of 2020, and later strengthened – already during the hot phase of the Russian-Ukrainian war – by additions to this agreement in terms of trade liberalization with Ukraine, as well as by the later agreement on security cooperation in 2024, which became the first such precedent in a number of bilateral security agreements between Ukraine and other partner countries. Since 2022, the United Kingdom has been actively providing the armed support necessary to repel the Russian invaders, which consists in the transfer of various types of weapons and the training of the Ukrainian military. In the end, the Ukrainian issue became a point of contact in European-British relations, guided by the common interest of protecting the region from escalation by Russia and preventing it from undermining the fundamental principles of the international order.
Results of surgical treatment for drug-resistant temporal epilepsy and related predictors of negative post-surgery outcome
Authors: Al-Sahli O.A.M. , Tibekina L. M. , Ivanova A. E.
Published: October 2024

Objective: to evaluate the results of surgical treatment and identify related predictors of unfavorable outcome in patients with temporal drug-resistant epilepsy (DRE) in long-term postoperative period.

Material and methods. Fifty-one patients with temporal lobe DRE were examined using clinical, neuroimaging, electro- physiological, and laboratory research methods from June 2020 to June 2023. Anteromedial temporal lobectomy (AMLE) and selective amygdalohippocampectomy (SAHE) were performed in 38 (74.5%) and 13 (25.5%) cases, respectively. Postsurgery outcomes were evaluated in 51 patients 6 months later, continued in 43 and 20 patients 1 year and 2 years, respectively, afterwards.

Results. The percentage of patients with significant improvement (Engel I/II) 6 months, 1 year and 2 years post-surgery was 82.4%, 72.1%, and 55.0%, respectively. After AMLE vs. SAHE, patients had a more favorable outcome while assessing seizure control. The predictors of unfavorable post-surgery outcome included a prolonged epilepsy course before surgery, the presence of electroencephalography-verified epileptiform activity in postoperative period, and repeated surgical intervention. Patient age, the presence of focal seizures evolving into bilateral tonic-clonic seizures as well as more frequent seizures before surgery were considered as potential predictors.

Conclusion. The study results show that quite high effectiveness of seizure control in postoperative period in temporal DRE is quite high that may be accounted for by probability of removing epileptogenic foci and suppression of the mechanisms ensuring emergence and irritation of epileptic discharges. Nevertheless, effectiveness of surgical treatment fades off with time, which requires to further investigate the negative factors countering long-term post-surgery effect. In connection with this, a special attention should be paid to factors such as the presence of electroencephalography-verified epileptiform activity in postoperative period, repeated surgical intervention as well as prolonged epilepsy before surgery.
Foreign Approaches to Protecting Business Reputation of Legal Entities
Authors: Zaitsev V. V.
Published: October 2024

The paper is devoted the problem of protecting the business reputation of legal entities in Russia and in foreign countries. The author elucidates various approaches to the definition and protection of business reputation and the possibility of compensation for moral harm caused to legal entities. The paper provides examples from the legislation and judicial practice of various countries, including Russia, Armenia, Belarus, Kazakhstan, Kyrgyzstan, Brazil and China. The legislation of the EAEU and BRICS member states differs in approaches to protecting the business reputation of legal entities. In some countries, such as Armenia, Belarus and Kazakhstan, legal entities are not granted the right to compensation for moral damage, but they can demand refutation of defamatory information and compensation for damages. In Kyrgyzstan and Brazil, legal entities can claim compensation for moral damage. In China, the reputation of legal entities is protected on an equal basis with individuals, while taking into account public interests.
Comrades' Courts in the Soviet Period of Russian Statehood as a Form of Non-Professional Justice
Authors: Gavrilova A. V.
Published: October 2024

The formation and development of comrades’ justice in the Soviet period of Russian statehood is associated with the implementation of the unified national concept of the court, conditioned not so much by professional justice as by the mass participation of non-professional judges from the people in court. The jurisdiction of cases heard in public courts was regulated by the relevant provisions and criminal codes, providing that these courts considered minor crimes, both by virtue of a direct indication in the law, and by way of delegation of the function of justice by the courts or the prosecutor’s office in each specific case. The activities of the comrades’ courts are divided into three periods. The first period — from 1919 to 1922 — is characterized by the disciplinary orientation of the comrades’ courts authorized to consider all violations of labor legislation. The second period — from 1928 to the beginning of the Great Patriotic War — is characterized by a variety of     comrades’ and public courts that covered various spheres of economic, social and political activities, from Soviet enterprises and institutions to collective farms. Its main purpose was to free public courts from a mass of minor offenses and property disputes, as well as ensuring productivity growth and combating disruptors of production in enterprises and institutions. The third period — from the late 1950s to 1991 — set the goal of strengthening socialist democracy by involving a wide range of workers in the management of public affairs, including through comradely justice, which defined comrades’ courts as quasi-judicial bodies of public and state power, intrinsically inscribed in the concept of a socialist national state.
Mikhail M. Speransky and his Constitutional Project
Authors: Akhmyatzhanova D. R.
Published: October 2024

Mikhail M. Speransky was a versatile person, who knew law, politics, philosophy, mathematics, physics, eloquence. Even Napoleon was impressed by the sharpness of the mind of the Russian political figure. The statesman clearly understood the needs of the society of the 19th century, realized what and how it was necessary to bring the Russian Empire into the state system in order to improve it. Indeed, a detailed analysis of the constitutional project of the great reformer is of great importance for the history of Russia. Thus, research on this topic remains relevant now. Mikhail M. Speransky is a key figure who found himself at the junction of two eternally opposing movements of socio-political thought, namely: conservatism and liberalism. The reformer was a supporter of liberal transformations, but for their successful implementation it was necessary to have a society, albeit conservative, but internally ready for new trends in politics, state and law. Why did a statesman with radical views fail to fully implement his ambitious plans? Is his large-scale plan only a ghostly illusion? The paper examines the main directions of the liberal policy of Mikhail M. Speransky in the process of creating and trying to implement a constitutional project, analyzes objective and subjective socio-historical factors that influenced the possibility of the actual implementation of the ideas of an astute and wise state and legal figure. Special attention is also paid to the significance of the personality of Mikhail Mikhailovich — a reformer with radical views — in the history of our country. Undoubtedly, Mikhail M. Speransky formulated a large number of liberal postulates governing the creation of a rule of law. Echoes of some of his ideas can be seen in modern concepts and principles implemented in Russia.
Seismic Discrimination Using Regional Distance Coda-Wave Ratios
Authors: Kintner Jonas A. , Delbridge Brent , Alfaro-Diaz Richard , Scott Phillips W.
Published: October 2024

This study utilizes regional seismic coda-wave amplitude ratios to distinguish earthquakes and declared nuclear explosions in the Democratic People’s Republic of Korea (DPRK). We compute the coda spectral ratios at common stations to isolate source information from propagation and site effects. The resulting frequency-dependent amplitude ratios help identify differences between source types at DPRK. We use parametric models to validate observations, linking them to seismic source parameters. Our method effectively distinguishes the spectral signatures of explosions, nearby earthquakes, and a post-explosion collapse event. The measurements show clear differences between source-type combinations and agree with estimated seismic source models. Notably, the coda spectral ratios between explosions and earthquakes indicate that explosive sources exhibit relatively lower high-frequency S-wave energy and corner frequency compared to P waves. We leverage these spectral differences to develop a Bayesian inference framework for seismic source discrimination at the DPRK test site. This study demonstrates that spectral differences between source types can be exploited in coda spectral ratios to provide critical information for seismic discrimination.

Abstract
Bryophytes have, in their chemical composition, important bioactive metabolites that can be used to control insect pests, such as Spodoptera frugiperda (JE Smith). This study reported the antifeedant and insecticidal effects of the ethanolic extract of Calymperes lonchophyllum Schwägr. on 3rd instar S. frugiperda larvae. Five treatments were tested (control; 2.00; 1.00; 0.50 and 0.25 mg/ml of extract), with five replications, totaling 25 bioassays, each containing a leaf disc treated with 50 µl of control (water and DMSO) and the four concentrations of the extract and one caterpillar. The antifeedant and mortality evaluations were performed after 24, 48 and 72 hours of the experiment. The results indicated that, after 48 hours, the treatments with the concentrations 2.00 and 1.00 mg/ml already showed an antifeedant action on the caterpillars, as well as such concentrations demonstrated an insecticidal effect, in 72 hours. Based on this, this is the first study carried out in Brazil with C. lonchophyllum, and indicated the potential of the ethanolic extract of this species of moss for biotechnological applications aimed at controlling pests of the genus Spodoptera spp.

Parientes y emprendedoras. Formas de participación de mujeres en el mercado local ilegal de drogas en la ciudad de Rosario (Argentina)
Authors: Cozzi Eugenia
Published: October 2024

This article proposes, through a predominantly ethnographic approach, the analysis of the forms of participation of women in activities linked to the local illegal drug market in the city of Rosario (Argentina). It is interesting to ask what the specific modalities of participation are like in this predominantly masculine universe. In other words, it is worth asking if this form of participation always occurs from a place of subordination or if women also occupy spaces of power, authority and/or leadership. To this end, an empirical universe composed of in-depth interviews and conversational situations held with female inmates in the women’s prison in the city of Rosario in Argentina, carried out during the years 2022 and 2023, is analyzed.

Published: October 2024

Counseling services are very important to help children find meaning in life and overcome the various problems they face as adults. Children are the future of the nation and need attention; many of them lose their identity during adolescence but can lead good lives with an intact family. The aim of this study is to understand the implementation of counseling services in developing the meaningfulness of life for orphans at the Al-Washliyah Orphanage in Lubuk Pakam, Indonesia. The method used is a qualitative approach. The subjects of this study are the children of the Al-Washliyah Orphanage in Lubuk Pakam, Lubuk Pakam District, Deli Serdang Regency, North Sumatra, Indonesia. The results of the study show that the success of the counseling services at the Al-Washliyah Orphanage in Lubuk Pakam can be seen from several indicators, such as understanding a clear purpose in life, knowing how to find meaning in daily activities, recognizing their potential and knowing how to develop it, valuing life experiences, having positive relationships with others, creating a harmonious family within the orphanage, feeling gratitude and accepting themselves without comparing themselves to others, being optimistic about their life choices, learning valuable lessons from suffering, and having spirituality with the belief that Allah SWT loves them. The activities provided by the counselors to the children in the orphanage include religious activities such as prayer guidance, teaching reading and writing of the Qur'an, and moral guidance. The children at the orphanage can understand their purpose in life through various processes and activities conducted during their stay.

O apagamento da memória como um processo estrutural da urbanização de São Paulo no século XX
Authors: Silva Marcos Virgílio da
Published: October 2024

Este artigo tem como objetivo comparar os diferentes momentos da história da urbanização em São Paulo e indicar como o processo de destruição de certos espaços significativos para a memória de alguns grupos sociais pode ser visto como mais do que uma sucessão de eventos fortuitos. Em vez disso, é tão extraordinariamente regular que é possível reconhecer um padrão de transformação do espaço urbano baseado no desrespeito à memória e à identidade urbana popular diante dos ditames do "progresso". Um dos traços desse desrespeito é a maneira pela qual a porção mais pobre e muitas vezes negra da população é frequentemente a principal vítima da principal vítima da descaracterização de seus lugares de memória. Esta investigação baseia-se na comparação entre a leitura de fontes iconográficas que mostram a transformação de determinados espaços da cidade, comparada com a análise de músicas que narram ou descrevem espaços significativos e suas mudanças.
Norwida Autoportret z grecką inskrypcją
Authors: Chlebowska Edyta
Published: October 2024

Artykuł omawia nieznany rysunkowy autoportret Cypriana Norwida powstały w Rzymie w 1845 r. odnaleziony ostatnio w zbiorach prywatnych. Ujęty w kameralną scenę rodzajową rysunek znajduje szereg analogii w autoportretowej spuściźnie artysty, przy czym najwięcej wspólnych cech łączy go z zaginionym wizerunkiem Dolce far niente pochodzącym z tzw. Albumiku włoskiego. Autoportret ujęty jest w pogodnym, nieco żartobliwym tonie, choć jego twórca uwzględnił szereg szczegółów, wykraczających poza realia życia salonowego w stronę szerokiego kręgu literackich oraz artystycznych odniesień. Mowa o zgromadzonych u boku młodzieńca dziełach Szekspira, Calderona, Kochanowskiego i Dantego oraz o umieszczonym w górnej partii rysunku starożytnym greckim cytacie z którym łączy się również sylwetka przybranej w antykizowany kostium kobiety towarzyszącej rysunkowemu wizerunkowi artysty. W artykule omówiono kwestie związane z pochodzeniem, znaczeniem oraz szerszym kontekstem przywołanego cytatu, pochodzącego z rzymskiej steli nagrobnej, a odnoszącego się pośrednio do starożytnej opowieści o porwaniu Hylasa przez nimfy. Podjęto także próbę interpretacji całego rysunku w świetle znaczeń generowanych przez starannie przepisany fragment starożytnej inskrypcji.

Authors: Кенжегалиева А.Р. , Жамболова А.Б. , Онгарбаев Е.К.
Published: October 2024

В краткой обзорной статье рассмотрена модификация нефтяных битумов и асфальтобетонных смесей углеродными наноматериалами. В качестве углеродных наноматериалов выбраны углеродные нанотрубки, фуллерены и графен. Показано влияние добавок углеродных наноматериалов на физико-механические характеристики битумов, полимер-битумных вяжущих и асфальтобетонных смесей. Содержание углеродных наноматериалов при модификации битумов, полимер-битумных вяжущих и асфальтобетонных смесей не превышает 5 мас. %, в среднем оставляет около 1 мас. %. Модификация битумов и асфальтобетонных смесей углеродными наноматериалами приводит к повышению температуры размягчения, вязкости, предела прочности на сжатие и снижению глубины проникания иглы и растяжимости. При этом улучшаются степень эффективности битумов и параметр устойчивости к колееобразованию. В обзоре также приводятся сведения о механизме действия углеродных наноматериалов на состав и свойства битумов и асфальтобетонов. Показаны преимущества и недостатки модификации битумов, полимер-битумных вяжущих и асфальтобетонных смесей углеродными наноматериалами. Применение модифицированных наноматериалами битумных вяжущих для дорожных покрытий экономически выгодно из-за многократного увеличения срока их службы. Необходимы дальнейшие исследования для лучшего понимания использования наноматериалов в качестве модификатора битумов на фундаментальном уровне, а также их эксплуатационных характеристик.

Flawonoidy – naturalne związki o potencjale przeciwwirusowym i przeciwnowotworowym
Authors: Sergiel Iwona
Published: October 2024

Flavonoids are a group of plant secondary metabolites that have a number of health-promoting properties and have both preventive and therapeutic effects. Research confirms that flavonoids work, among others: antiviral and anticancer. Apigenin, luteolin, isorhamnetin, kaempferol, myricetin, quercetin, hesperetin, naringenin, epicatechin and genistein have documented antiviral activity. The discovery of the anticancer activity of flavonoids (including apigenin, naringenin, hesperetin) initiated a number of studies to identify the most active compounds against various cancers and to understand the mechanism of their action. However, the relationship between flavonoid intake and cancer risk appears to be non-linear. Available literature data suggest that flavonoids may act as therapeutic agents in the early stages of virus infection and as an anticancer agent and should be included in the daily diet by increasing the consumption of primarily fruit (chokeberry, elderberry, cherry, mandarin), vegetables (parsley, celery, onion) and herbs and spices (mint, oregano, lovage, moringa, saffron). Flavonoids present in food are transported by passive diffusion (hydrophobic aglycones) and by active transport (hydrophilic glycosides). Individual classes of flavonoids differ in the amount they appear in food, the metabolites they produce and their possible impact on health. The aim of this review is to summarize the current knowledge on the potential use of selected flavonoids in the treatment of diseases of various etiologies, with an indication of their anticancer and antiviral effects. The perspectives and possibilities of using these compounds are presented, taking into account the problems resulting from their bioavailability.

Published: October 2024

Realization of the determined targets in drastically changed working conditions requires development of new approaches, new business models and ideas of management. As a consequence, managerial practice and methods significantly changed in the last decade of the 20th century and those changes have been continuing in the 21st century. In that context, contemporary trends present in the managerial accounting are associated with its strategic concepts, such as: activity based costing system, just-in-time system and total quality management. Starting from the a.m., the main objective of this research will be directed towards providing data for that if Macedonian business entities are familiar with these concepts and how much they implement them. For this purposewe carried out a survey on a representative sample of Macedonian companies.The examination conducted in this paper shows that business entities in R. Macedonia still apply these accounting techniques not sufficiently. Obtained results are presented within this paper in details.

Published: October 2024

This paper presents a power loss analysis for a Single Ended Parallel Resonance (SEPR) Converter used for induction heating. The analysis includes a comparison of the losses in the electronic switch when the circuit is realized using a conventional Silicon (Si) based IGBT or when using Silicon Carbide (SiC) based MOSFET. The analysis includes modelling and simulation as well as experimental verification through power loss and heat dissipation measurement. The presented results can be used as a base of comparison between the switches and can be a starting point for efficiency based design of those types of converters.
Discipline, Good Faith and Payment’s Loyalty –Main Factors for Reducing the Corporate Indebtness in Bulgaria
Authors: Stoyanova Slavena
Published: October 2024

As a member of the European Union Bulgaria is subject to monitoring, including in the field of ecomomy. Our country complies with the rules and procedures imposed by the common European policy. Although recent analyses indicate a slight decline in corporate indebtedness, it also maintains the same high levels, thus it hides certain risks for businesses in all sectors of the economy. The delayed payment to a counterparty leads to an avalanche of delayed payments. The need for discipline, good faith and fair payments is tangible.

Published: October 2024

Autoclaved Aerated Concrete (AAC) is a porous light weight concrete obtained by adding a pore-forming material to a mixture made of finely pulverized siliceous aggregate and inorganic binder (lime and/or cement) and hardened by steam cure. In this study fly ash was used instead of siliceous aggregate and experiment samples were obtained by adding 3%, 6%, 9%, 12% silica fume to the cement. Samples were cured under 1560C and 4 bars and 1770C and 8 bars, and were investigated for compressive strength, bulk density and ultrasound pulse velocity to determine their mechanical and physical properties. Microstructure of samples was observed by using SEM and XRD techniques. Samples’ bulk density values and compressive strengths are changing between 0.6-0.7 kg/dm3 and 2.5-4.4 MPa respectively.

Published: October 2024

The series ISO 14001 of international voluntary standards is an effective tool for improving organizational environmental performance and implementation of sustainable approach to energy management. These standards established and implemented a systematic management plan. Plan is made to continually identify and reduce environmental impacts. Eco-management approach may be suitable because its implementation is a possible way to replace the widely used environmental control system based on legislation and controlling of the application of environmental and energy regulations. Eco-management systems can help companies to integrate environmental efforts into decision making. Application of eco-management system improves compliance with environmental regulations. Today, the number of companies in the world which tend to integrate the system of eco-management in their business strategies is rapidly increasing. They accept advanced technologies. Systems of eco-management encourage companies to consider environmental consequences of their operations. To reduce waste, risks and costs the companies then define strategies which would help them.
Determining a Proper Text Similarity Approach for Resume Parsing Process in a Digitized HR Software
Authors: Özçevik Yusuf , Yücalar Fatih , Demircioğlu Murat
Published: October 2024

Resume parsing is one of the costly phases of a recruitment process. This phase has been alleviated in digitized human resources recently by using text processing approaches between a job advertisement content and resume of applicants. For this purpose, performing a text similarity calculation is one of the most commonly used approaches. However, there are lots of similarity calculation models and most of them are not targeted a recruitment process. Moreover, a subjective assessment of such approaches is required to provide a proper text processing in such a specific problem domain. Thus, in this paper, we offer to evaluate different similarity score calculation approaches through a recruitment case study with the help of a statistical assessment. For this purpose, a computer-aided resume evaluator on a set of resumes is proposed, a human evaluation on the same set of resumes is performed by the professions and the correlation between the outcomes is sought out. As a conclusion, a discussion among different similarity score calculation approaches available for resume processing is presented to find out a proper computer-aided resume evaluator for digitized human resources.
Evaluation of variability of morphometric traits of plants and age spectrum of cenopopulations of Matthiola daghestanica (Brassicaceae) of the Piedmont and Mid‐mountain Dagestan, Russia
Authors: Osmanov R. M.
Published: October 2024

Aim: Study of intra‐ and interpopulation variability of quantitative traits of Matthiola daghestanica (Conti) N. Busch and assessment of the age spectrum of natural cenopopulations of Piedmont and Mid‐mountain Dagestan. The material consisted of 90 plants (shoots with inflorescences) taken from coenopopulations of various locations of the studied species (450, 610 and 960 m above sea level). An analysis of the variability of 12 morphological traits of M. daghestanica was carried out. To assess the age spectrum, 5x5 m test plots were laid out at three points (75 m²), where the age (ontogenetic) states of M. daghestanica guided by methods from the works of T.A. Rabotnov (1950) and A.A. Uranov (1957).

The variability of the morphological traits of the Dagestan endemic M. daghestanica has been studied and its age spectrum in the natural cenopopulations of Piedmont and Mid‐mountain Dagestan has been assessed. The most variable were the weight traits. Analysis of the significance of the differences between the selected groups using the t‐test confirmed that “Chakh‐Chakh” is highly isolated from other coenopopulations, and to the greatest extent from “Chirkata”. The linear trait “length vegetative features” introduces the greatest significant differences between all coenopopulations. The percentage of age states from the total number of individuals varies among populations. The age spectrum of M. daghestanica in the “Chirkata” cenopopulation is represented by a predominance of the juvenile (25 %) and virginal (25 %) groups and in the “Ashilta” cenopopulation by the adult group (23.9 %). Among the age states of the generative period in all cenopopulations, young generative individuals prevail (16.7–19.4 %). The largest number of middle‐aged generative individuals is in the “Chakh‐Chakh” cenopopulation (16.3 %).

Analysis of the variability of morphological characteristics of M. daghestanica plants showed that linear and numerical traits for the three cenopopulations are less variable. Significant variability was revealed in weight characteristics: “mass caulis and leaves” (518.3–818.7 mg); “total mass shoot” (990.7–1342.8 mg). The squared Mahalanobis distances of the characters studied revealed the isolation of the “Chakh‐Chakh” cenopopulation from the other two (“Achilta”, “Chirkata”). The age spectrum of M. daghestanica coenopopulations is similar in the Piedmont and Mid‐mountain Dagestan, despite the different number of age states. Cenopopulations of M. daghestanica are normal, capable of self‐renewal, characterized by recovery indices of 1.2–2.8 %.

Aim. To identify economically significant species of segetal plants of agrophytocenoses in the Southern Non‐Chernozem zone and assess their dynamics with changes in anthropogenic load.

The study was carried out by analysing geobotanical descriptions of agrophytocenoses in the Southern Non‐Chernozem Zone. The species diversity of economically important species was established during the period of extensive farming (1929–1933), the beginning of intensification (1936–1938), a high level of intensification (1981–1983), and a period of decreasing intensity of farming (2012–2022).

At all stages of the study, groups of forage, medicinal and honey plants were round to have a high species diversity. The presence of individual representatives of vegetable, vitamin, insecticidal and ornamental species in agrophytocenoses was established.

Changes in the nature and degree of anthropogenic pressure on agrophytocenoses has led to a significant transformation of species composition and abundance of representatives of economically significant groups. The smallest number of these was noted in the 1980s. Currently, species diversity has increased due to a decrease in the intensity of agriculture in the region.
