Abstract. Plants emit biogenic volatile organic compounds (BVOCs) in response to changes in environmental conditions (e.g. temperature, radiation, soil moisture). In the large family of BVOCs, isoprene is by far the strongest emitted compound and plays an important role in ozone chemistry, thus affecting both air quality and climate. In turn, climate change may alter isoprene emissions by increasing temperature as well as the occurrence and intensity of severe water stresses that alter plant functioning. The Model of Emissions of Gases and Aerosols from Nature (MEGAN) provides different parameterizations to account for the impact of water stress on isoprene emissions, which essentially reduces emissions in response to the effect of soil moisture deficit on plant productivity. By applying the regional climate–chemistry model RegCM4chem coupled to the Community Land Model CLM4.5 and MEGAN2.1, we thus performed sensitivity simulations to assess the effects of water stress on isoprene emissions and near-surface ozone levels over the Euro-Mediterranean region and across the drier and wetter summers over the 1992–2016 period using two different parameterizations of the impact of water stress implemented in the MEGAN model. Over the Euro-Mediterranean region and across the simulated summers, water stress reduces isoprene emissions on average by nearly 6 %. However, during the warmest and driest selected summers (e.g. 2003, 2010, 2015) and over large isoprene-source areas (e.g. the Balkans), decreases in isoprene emissions range from −20 % to −60 % and co-occur with negative anomalies in precipitation, soil moisture and plant productivity. Sustained decreases in isoprene emissions also occur after prolonged or repeated dry anomalies, as observed for the summers of 2010 and 2012. Although the decrease in isoprene emissions due to water stress may be important, it only reduces near-surface ozone levels by a few percent due to a dominant VOC-limited regime over southern Europe and the Mediterranean Basin. Overall, over the selected analysis region, compared to the old MEGAN parameterization, the new one leads to localized and 25 %–50 % smaller decreases in isoprene emissions and 3 %–8 % smaller reductions in near-surface ozone levels.

Published: October 2023

Abstract. Global Navigation Satellite Systems (GNSS) radio occultation (RO) is a space-based remote sensing technique that measures the bending angle of GNSS signals as they traverse the Earth's atmosphere. Profiles of the microwave index of refraction can be calculated from the bending angles. High accuracy, long-term stability, and all-weather capability make this technique attractive to meteorologists and climatologists. Meteorologists routinely assimilate RO observations into numerical weather models. RO-based climatologies, however, are complicated to construct as their sampling density is highly non-uniform and too sparse to resolve synoptic variability in the atmosphere. In this work, we investigate the potential of machine learning (ML) to construct RO climatologies and compare the results of a ML construction with Bayesian interpolation (BI), a state-of-the-art method to generate maps of RO products. We develop a feed-forward neural network applied to COSMIC-2 RO observations and simulate data taken from the atmospheric analyses produced by the European Centre for Medium-Range Weather Forecasts (ECMWF). Atmospheric temperature, pressure and water vapor are used to calculate microwave refractivity at 2, 3, 5, 8, 15, and 20 km geopotential height, with each level representing a different dynamical regime of the atmosphere. The simulated data are the values of microwave refractivity produced by ECMWF at the geolocations of the COSMIC-2 RO constellation, which fall equatorward of 46 latitude. The maps of refractivity produced using the neural networks better match the true maps produced by ECMWF than maps using BI. The best results are obtained when fusing BI and ML, specifically when applying ML to the post-fit residuals of BI. At the six iso-heights, we obtain post-fit residuals of 10.9, 9.1, 5.3, 1.6, 0.6 and 0.3 N-units for BI and 8.7, 6.6, 3.6, 1.1, 0.3 and 0.2 N-units for the fused BI&ML, respectively. These results are independent of season. The BI&ML method improves the effective horizontal resolution of the posterior longitude-latitude refractivity maps. By projecting the original and the inferred maps at 2 km iso-height onto spherical harmonics, we find that the BI-only technique can resolve refractivity in the horizontal up to spherical harmonic degree 8 while BI&ML can resolve maps of refractivity using the same input data up to spherical harmonic degree 14.
Wind comparisons between meteor radar and Doppler shifts in airglow emissions using field widened Michelson interferometers
Authors: Kristoffersen Samuel Kaare , Ward William Edmund , Meek Chris E.
Published: October 2023

Abstract. Winds from two co-located two wind measuring instruments, a meteor radar and field widened Michelson interferometer at the Polar Environment Atmospheric Research Laboratory in Eureka, Nu, Canada (80° N, 86° W) are compared. The two instruments have very different temporal and spatial observational footprints. ERWIN provides airglow weighted winds from three nightglow emissions (O(1S) (oxygen green line, 557.7 nm), an O2 line (866 nm), and an OH line (843 nm)) on a ∼5 minute cadence for measurements at all three heights. As with Fabry-Perot airglow wind observations, these winds are airglow weighted winds from volumes of ∼8 km in height by ∼5 km radius. ERWIN’s higher accuracy (1–2 m/s for the O(1S) and OH emissions and ∼4 m/s for the O2 emissions) and higher cadence allows more detailed wind comparisons of airglow and radar winds than previously possible. The best correlation is achieved using Gaussian weighting of meteor radar winds with peak height and vertical width being optimally determined. Peak heights agree well with co-located SABER airglow observations. Offsets between the two instruments are ∼ 1–2 m/s for the O2 and O(1S) emissions and less than 0.3/s for the OH emission. Wind direction are highly correlated with a ∼ 1:1 correspondence. On average meteor radar wind magnitudes are ∼ 40 % larger than those from ERWIN. Gravity wave airglow brightness weighting of observations is discussed. Non-quadrature phase offsets between the airglow weighting and gravity wave associated wind and temperature perturbations will result in enhanced or reduced layer weighted wind amplitudes.

Published: October 2023

Abstract. In August and September 2022, Pakistan was hit by a severe flood, and millions of people were impacted. The Sentinel-1-based flood mapping algorithm developed by Technische Universität Wien (TU Wien) for the Copernicus Emergency Management Service (CEMS) global flood monitoring (GFM) component was used to document the propagation of the flood from 10 August to 23 September 2022. The results were evaluated using the flood maps from the CEMS rapid mapping component. Overall, the algorithm performs reasonably well with a critical success index of up to 80 %, while the detected differences can be primarily attributed to the time difference of the algorithm's results and the corresponding reference. Over the 6-week time span, an area of 30 492 km2 was observed to be flooded at least once, and the maximum extent was found to be present on 30 August. The study demonstrates the ability of the TU Wien flood mapping algorithm to fully automatically produce large-scale results and how key data of an event can be derived from these results.
Understanding masculinity in Turkey through the films of male auteur directors
Authors: Gürkan Hasan , Yarcı Işıl
Published: October 2023

This study focuses the representation of male characters in the films of contemporary male auteur directors in Turkey. Once Upon a Time in Anatolia (Zeki Demirkubuz, 2011), Underground (Demizkubuz, 2012), and Big World (Erdem, 2016) are explored using sociological film analysis. Unlike mainstream cinema, the protagonists in these directors’ films do not demonstrate hegemonic masculinity; the supporting male characters that do demonstrate hegemonic masculinity category are not white Turks. Arguably, the male characters embody a new hybrid hegemonic masculinity that combines various masculinities to reproduce patriarchy. It can be stated that “Others” in these films are negatively affected.
Deceptive Retrospective Narrative Strategy and Synchronistic Prerequisite: Case Study on The Design of Impossible Puzzles
Authors: Yang Yu
Published: October 2023

The deceptive clues in the impossible puzzle film confirm the viewer’s internal expectations and allow retrospective attributing. In the film, a transcendental object negates an internal expectation, causing a retrospective blockage. Retrospectivity does not stop there; the transcendental object reinterpreting deceptive clues in the associative area leads to repeated attribution. This article consists of three parts. First, it discusses impossible puzzle films in the context of complex narrative classification. The following section introduces the Jungian concept of synchronicity and illustrates how it works. The article concludes with a case study of Long Day’s Journey into Night (2018), which contains more complicated puzzles and explains how mind-game narrative techniques create deceptive clues and induce deceptive retrospective attribution.

Published: October 2023

Background: In the Brazilian northeast region, the leaves of a plant scientifically known as Aristolochia cymbifera (A. cymbifera) are therapeutically used to treat different conditions, including fevers, ulcers and stomach disorders. Objective: To explore its effects in the oral cavity, this study aimed to evaluate the presence of morphological, cellular, and tissue modifications in the oral mucosa of rats treated with different A. cymbifera solutions. Materials and Methods: The rats were divided into 6 groups: Group 1 was treated with 0.3 ml of vehicle (DMSO and water); Group 2 treated with 0.3 ml of A. cymbifera-ethanolic extract 4mg/ml; Group 3 treated with 0.3 ml of A. cymbifera-hexane extract 4mg/ml; Group 4 treated with 0.3 ml of A. cymbifera-ethanolic extract 10mg/ml; Group 5 treated with 0.3 ml of A. cymbifera-hexane extract 10mg/ml; and Group 6 treated with 0.3 ml of chlorhexidine gluconate 0.12%. All groups were treated twice daily by applying the solutions into the oral cavity, over a total period of 24 days. To analyze cytotoxicity on cells, the micronucleus test was performed, and an additional histopathologic analysis was conducted in order to evaluate tissue changes such as inflammatory infiltration, desquamation, and degeneration of cells. Results: Results showed that the cytotoxicity of the A cymbifera -based solutions was similar to those of chlorhexidine, and all groups showed morphological characteristics of normal mucosa after treatments. Conclusion: It is concluded that no cytotoxicity was present after treatment with extracts of Aristolochia cymbifera, showing its potential for the development of future clinical trials.
Religious administration of the Gdańsk Voivodeship towards the allocation of bells from post-Evangelical temples in Powiśle after 1945. Case study
Authors: Krupa Andrzej B.
Published: October 2023

Ludność, osiedlająca się na Powiślu po 1945 roku przejmowała na potrzeby kultu świątynie poewangelickie. Obiekty te były w różnym stopniu uszkodzone lub zdewastowane. Brakujące wyposażenie, w tym dzwony uzupełniano między innymi z nieczynnych kościołów protestanckich. W 1948 roku przeniesiono dzwony z Mikołajek Pomorskich do Sztumskiej Wsi. Wobec konfliktu, który w związku z tym powstał gdańska administracja wyznaniowa oficjalnie zachowywała neutralność. Dzwony z kościoła poewangelickiego w Łozie zostały natomiast zakwalifikowane w 1953 roku jako źródło surowców wtórnych. Instrumenty jednak najprawdopodobniej przetrwały tylko dzięki nieudolności władz powiatowych w Sztumie. Najpewniej są wykorzystywane w którejś z parafii katolickiej północnej Polski.
Incorporating diminishing returns to opportunities in access: Development of an open-source walkability index based on multi-activity accessibility
Authors: Roper Josephine , Ng Matthew , Pettit Christopher
Published: October 2023

In this paper, we argue for an explicit decoupling of “walkability” and “walking behavior” and for the advantages of a definition of walkability based on access. This provides impetus for a new approach to constructing and using walkability indices, combining accessibility theory with a goal of comprehensiveness and communicability. Diminishing returns-to-opportunities can be used to map the infinite origin-destination gravity potential space to a finite scale thus creating an easily communicable metric, or metrics. In addition, this method can be applied to any mode and applied to multiple destination types singly or combined. Application of this theoretical approach is demonstrated through the creation of a novel comprehensive open-source transport walking potential index, WalkTHERE. A 0-100 scale is used to represent the percentage of people’s total needs potentially accessible by walking. The index is applied to eight Australian and two European cities, and the specific data considerations and parameters chosen are described. Significant disparity is shown in walking access between different destinations within cities, and in walking access between cities. Walking access to recreational opportunities is highest, followed by education and shopping, with very little employment access for most residents. Avenues for expansion and further validation are discussed.

This study aims to assess the impact of gold mining operations on the socioeconomic well-being of the Paring Lahung Village community in the Montallat District of North Barito Regency. The research utilizes both secondary and primary data sources. Secondary data is collected from many sources, such as the Central Bureau of Statistics (BPS), sub-district offices, villages/districts, and private entities. On the other hand, primary data is directly received from respondents residing in Paring Lahung Village, Montallat District, North Barito Regency. For a sample size of 30 participants. The research findings indicate that there is a discernible public impression regarding the presence of unauthorized gold mining operations in Paring Lahung Village. The findings indicate that the residents of Paring Lahung Village have a predominantly neutral stance towards gold mining operations. Out of the total number of respondents, 14 individuals (46%) expressed a positive attitude towards gold mining activities in the vicinity of the Paring Lahung Village forest area. Additionally, 9 respondents (30%) had a neutral view, while 7 respondents (24%) exhibited a negative attitude towards such activities. The present study examines the social, economic, and environmental conditions associated with the presence of gold mining activities in Paring Lahung Village. The analysis of social situations reveals that individuals distribute their wealth towards several sectors, including education, health, and housing. The economic conditions demonstrate a tendency towards above-average performance and have exhibited growth subsequent to the implementation of gold mining operations. This can be attributed to the augmentation of respondents' primary income, as well as the acquisition of supplementary sources of revenue. In Paring Lahung Village, the prevailing environmental conditions indicate the utilization of a method to separate combined gold and sand, alongside a minority engaging in conventional processing techniques. As per the accounts of certain inhabitants, the procedure of gold extraction involves the utilization of quicksilver, often known as mercury. Mercury is categorized as a heavy metal with the capacity to be designated as B3 trash

Published: October 2023

The prevalence of cyberbullying and associated psychological problems on the victims has been on the increase, especially in the developing countries. While studies on the effects of cyberbullying and management of the victims have been done in developed countries, this is not the case in many developing countries. Therefore, this study investigated predictors of cyberbullying behavior among youths in Ibadan metropolis, Nigeria. Cross-sectional survey design was adopted while purposive sampling technique was used to select the two institutions. Data was collected from 416 students using three validated scales. Two hypotheses were tested using stepwise multiple regression analysis and t-test of independent samples. Results indicated that personality traits significantly predicted cyberbullying behavior among students in the two tertiary institutions. When aggression was introduced into the model, there was an additional amount of variance explained. Furthermore, the result revealed that male students reported higher cyberbullying behavior than female students. The study concluded that personality traits of extraversion, openness to experience, conscientiousness, neuroticism, and aggression are important predictors of cyberbullying behavior among students in the study population. The study recommended that discouraging cyberbullying would be achieved by understanding the personality traits and aggressive behavior that triggers students into cyberbullying.

Published: October 2023

In this study, in line with TIMSS 2019 data, 8th grade students' school engagement in the Turkish education system and various variables in the field of science and mathematics, which are thought to be related to school engagement, were examined with the Random Forest method, a method amongst data mining methods. This research focuses on student bullying, which includes psychological factors at school, such as whether students like or dislike their lessons, their confidence in science, their self-confidence, absenteeism, and the effects of teachers' teaching methods on SE.  The sample of the study consisted of 3872 students in the science data set and 3802 students in the mathematics data set, which remained as a result of the lost data deletion and assignment processes from 4077 students who originally participated in the application. The open-source Python infrastructure was used in the analysis of the data. Orange 3.32 data mining program was employed for model setup. The model performance criteria MSE, RMSE, MAE and R2 values obtained as a result of the analysis. In both areas, the variables that contribute to the prediction of students' school engagement were ranked according to their importance levels, starting from the most important, also interpreted and discussed. It was observed that the performance criteria of the established model have values close to zero in the field of science (MSE: 2.775 RMSE: 1.666 MAE: 1.267) and mathematics (MSE: 2.240 RMSE: 1.497 MAE: 1.131). Variables explain school engagement at the rate of 69.6% in science and 75.7% in mathematics. The order of importance of the variables in both areas showed a great similarity. Student bullying was obtained as the most important variable. Prospective studies can also be planned towards collecting more in-depth data deploying qualitative data collection methods under a qualitative research model that also includes the opinions of self, peers, teachers and parents. For the education policies that the TES should produce toward increasing SE, it is weighty to reduce and prevent student bullying in schools with sustainable practices. Exclusively school administrations should focus on student bullying with the help of counselors, diagnose the problems and take measures in and out of school according to the types of bullying.

Authors: Işık Metin
Published: October 2023

The objective of this research is to assess whether the distance education experiences of pre-service teachers currently undergoing higher education differ according to specific variables. These variables relate to the distance education processes instituted following the COVID-19 pandemic and the earthquakes that took place in Maraş and Elbistan on February 6, 2023. The study also endeavors to discern the impact of distance education on pre-service teachers' attitudes toward the teaching profession. Employing a mixed methodology, the research engaged a sample of 300 students from varying departments at Kırşehir Ahi Evran University during the 2022–2023 academic year, all of whom were participating in pedagogical formation courses via distance education. The quantitative data for the research was compiled using the "Pre-service Teachers' Perception of Distance Education Scale" developed by Gündüz (2013). Additionally, qualitative data was gathered from 50 volunteer pre-service teacher students engaged in pedagogical formation education using a semi-structured interview form designed by the researcher. An analysis of pre-service teachers' attitudes toward distance education and their chosen profession was conducted based on data derived from the scale. Quantitative data was processed with SPSS 25, while qualitative data was analyzed via the MAXQDA 2020 program. Quantitative analysis revealed that pre-service teachers' perceptions of distance education did not significantly differ in relation to gender, personal computer ownership, or field of study. However, differences were observed in relation to their internet connection status. Qualitative analysis generated sub-themes under the Distance Education theme, such as the Student in Distance Education and the Features of Distance Education.
Teacher Hiring Processes in Private Educational Institutions: Methods, Qualifications, and Challenges
Authors: Özsoy Metin , Tabancalı Erkan
Published: October 2023

This research aims to comprehensively analyze the teacher recruitment process in private education institutions. The study utilizes a qualitative case study method, and data was gathered through semi-structured interviews with five administrators from boutique schools and five administrators from chain schools. The findings of the interviews revealed three main themes: "Methods for Teacher Hiring," "Desired Teacher Qualifications," and "Challenges." Interviews and course practices emerged as the primary methods for evaluating the personal and professional qualifications of potential teachers. Private school administrators emphasized the significance of personal, professional, and organizational qualifications in their recruitment processes. The research identified several difficulties faced during the teacher recruitment process, including teacher shortages, issues with loyalty, salary concerns, limited options, a lack of transparency, and teacher transfers. This information suggests that private school administrators may need to address these challenges to attract and retain qualified teachers effectively. To improve the recruitment of highly qualified teachers, it is recommended that private school administrators diversify their human resource management methods. Additionally, they should establish legal specifications for private school establishments, prioritizing educational goals over financial concerns. Collaboration between relevant institutions, such as the Council of Higher Education and the Ministry of National Education, is necessary for planning university teacher training quotas and open appointment processes, taking into account the needs of private schools.

Published: October 2023

This study examines the relationship between gifted students' perfectionism and life satisfaction. It also aims to understand how perfectionism and life satisfaction differ according to variables such as gender, parental education level, number of siblings, and grade level for gifted students. The relational survey method, one of the quantitative research methods, was used. The sample of the study consists of 395 gifted 5th–8th grade students. The Positive and Negative Perfectionism Scale and the Life Satisfaction Scale were used to collect data within the scope of this research. Some findings show that life satisfaction and positive perfectionism were high and negative perfectionism low among gifted secondary school students. When their positive perfectionism increases, their life satisfaction increases, and when their positive perfectionism decreases, their life satisfaction decreases. The life satisfaction of gifted students does not differ according to their gender, and negative perfectionism was significantly higher in girls. The life satisfaction of the gifted student who was the only child in the family was higher than that of the gifted student who had two or more siblings. The life satisfaction of the gifted student whose mother had a master's degree or above was higher than that of others. As gifted students move from 5th to 8th grade, their life satisfaction decreases and their negative perfectionism increases.

In the contemporary educational landscape, principals' adeptness in technological leadership holds significant implications for fostering teachers' professional evolution. A mixed-method converging parallel design was employed in this study, facilitating both quantitative and qualitative data collection and analysis. The research sample comprised 418 teachers from various types of schools in Istanbul's districts of Beylikdüzü, Büyükçekmece, Silivri Avcılar, and Esenyurt during the spring term of the 2022-2023 academic year. Quantitative data were procured using the "School Principal Technological Leadership Behavior Scale (SPTLBS)" developed by Durnalı (2018). In contrast, qualitative data were gathered using an "Interview Form" curated by the researcher. Throughout the research process, the researcher ensured the participating teachers were fully informed about the measurement tool and their voluntary participation was respected. Descriptive statistical techniques, including arithmetic mean and inferential statistics, including t-tests, were used to analyze the quantitative data. For qualitative data analysis, the MAXQDA program was utilized. The study hypothesizes that school principals' technological leadership practices significantly impact teachers' professional development. Interestingly, the principals' technological leadership practices did not significantly vary according to the teachers' education level, age, tenure, or teaching field. In qualitative findings, participants suggested that the influence on teachers' professional development was jointly attributable to both the teacher and the principal.
INVESTIGATING THE DEPENDENCE OF ELASTOMERIC FRACTURE ON TEMPERATURE AND RATE
Authors: Wang Shi-Qing , Fan Zehao
Published: October 2023

Decades of elastomeric fracture phenomenology resulting from the work of Thomas and Smith demonstrated the remarkable fact that rubbers are stronger and tougher at lower temperatures. The prevailing explanation relates the fracture behavior to polymer viscoelasticity. Given the recent insight and evidence that toughness is influenced by material strength, we examine elastomeric fracture with a different perspective and conclude that chain scission dictates fracture characteristics, including its temperature dependence. Working within selected temperature ranges, stretching is shown to be entirely elastic at a stretching rate less than 0.17 s−1. We demonstrate that the same temperature and rate dependencies of strength and toughness, observed by Thomas and Smith, also occur in our crosslinked polybutadiene and styrene–butadiene rubber. The temperature effects on rate dependence of strength and toughness are found to be much stronger than that prescribed by the Williams–Landel–Ferry shift factor aT. Moreover, crack propagates, upon either stepwise stretching or during creep, at a much lower speed at lower temperature that cannot be rationalized with polymer relaxation dynamics. Our new interpretation is that a carbon–carbon bond is stronger at a lower temperature. Because backbone bonds are more stable, a higher degree of network stretching occurs before rupture at lower temperatures.

Khojanazar Huvaido is a mature representative of the Kokand literary environment and master poet. His lyrical legacy was published as a divan. The article compared the poet’s published divan with the lithograph called "Huvaidoyi Chimyoni" kept in the Bukhara Museum of Literature and Art. Also, a munajaat ghazal unknown to the scientific community and a musaddasi related to Navai’s ghazal are being published for the first time. The text of the ghazal and musaddas was analyzed based on its idea and artistic features, converted from the old Uzbek script to the current script. In the analysis, special attention was paid to the mystical content of the ghazal.

The Jadidism movement, which began practical activity in Turkestan at the beginning of the 20th century, became a great force in a short period of time. Intellectual and political movements in Turkestan were closely overwatched not only by the local Russian government officials, but also from abroad. In this regard, the periodical press of a new direction, which appeared in Turkey at the beginning of the 20th century, was different. In this press, a lot of messages, letters and analytical articles of various contents related to the social and political life of Turkestan, especially Bukhara Emirate, began to be published. Through these materials, the Turkish intellectuals of the beginning of the 20th century expressed their attitude towards those political events and as well as tried to inform the Turkish society about the social and political processes in Turkestan. In particular, the Turkish press closely followed the articles published in the Russian press about the future fate of the Bukhara Emirate. In this article, the articles published in the Turkish press about Turkestan are analyzed based on primary sources.

The new field of lingopersonology linguistically explores each per-son. Manifestation of the linguistic personality in the literary text is caused by several factors. In this article, the concept of gender in linguistics, the views of the female and male linguistic personality are studied, also the issue of the role of gender factors in determining the linguistic personal-ity is highlighted in the literary. Peculiarities in the formation of the lin-guistic personality are analyzed in the literary text. The embodiment of a linguistic personality in a literary, it is important for the writer to be the owner of the language, and for the hero of the opposite sex, it is import-ant to understand the world, express it through language, understand the unique aspects of reflecting the value attitude. The article discusses the role of lexical and syntactic units for the formation of a female linguistic personality in the stories of Zulfiya the daughter of Kurolboy.
Travel through the Empire of Bukhara or Uzbekistan

Many travelers from Europe came to Iran, Central Asia and India in the 17th and 18th centuries. One of the European travelers who traveled through Central Asia and wrote down detailed information about the peoples of the region was the Greek traveler Vassilios Vatatzis, who traveled for many еars from 1708 through the countries of Europe and Asia. Vasilio Vatazzi’s travelogue, Periegetikon (“Travels”), written in poetic Greek, is one of the rarest and least studied sources. His journey through Central Asia in 1727 – 1730 is especially important for us. In 1886, the main contents of the travelogue were abridged in French in prose. Recently, its English translation was done in the same way. But despite this, this travelogue and the valuable information in it are still unknown to scientists of Central Asia, including Uzbekistan. Below is a summary of the main content of this travelogue. The information given in the travelogue is compared with the traveler’s comments on the map of Central Asia.
The degree of study and classification principles of imitative words
Authors:   Uzbekistan State World Languages University., Qahhorova Iroda
Published: October 2023

The purpose of the article is to identify the typological features of modern English and Uzbek imitative words, semantic and contextual description, showing the norm of constant use, translation problems.The morphological, semantic and typological-structural state of mimetic expressions in modern English and Uzbek languages and the problems of mutual translation are highlighted in the research. In Uzbek, imitative words are morphologically divided into separate word groups between independent and non-independent word groups, while in English linguistics, imitative words and independent words formed from imitation are called onomatopeia. However, it was found that the independent words made from imitation in the morphological layer belong to one of the existing independent word groups according to their grammatical signs. Also, the disadvantages of translating imitative words from Uzbek to English, from English to Uzbek, including imitative words can be omitted in the translation text or expressed by transliteration.
Grammatical and functional characteristics of some standard tools in newspaper language
Authors:   The professor of the university of fine arts named after Memor Sinan, Seyhan Tanju , Bozorova Sabohat ,   Tashkent state university of Uzbek language and Literature named after Alisher Navai
Published: October 2023

This article discusses the grammatical and functional features of some standard tools used in newspaper language. Newspaper standards are sometimes used exactly in the process of covering the material, sometimes with different lexical-grammatical means, with certain changes, and in various forms. This change is sometimes characterized by their expansion at the expense of various components, and in some cases, the loss of one of the components of the compound is observed. As a result of these changes, the enrichment of functional synonymous lines in the vocabulary system increases. In some of them, new semantic and formal reconstructions occur. In this way, vocabulary becomes richer. This, in turn, has an active influence on the development of syntactic synonymy. As a result of changes in language rules and syntactic norms, we observe that several different functional options have been created due to the fact that standard expressions are not repeated exactly the same way and the language possibilities are used effectively and appropriately for other purposes.
