Published: July 2024

This research systematically investigates the impact of porphyrin and chlorophyll dyes on Dye-Sensitized Solar Cells (DSSC) performance, aims to achieve maximum solar cell efficiency. This investigation involved the use of Fluorine-doped Tin Oxide (FTO) coating with TiO2–ZnO composite, incorporating Al doping, and introducing variations in the concentration of chlorophyll SP and porphyrin (2:2:0.1 and 2:2:0.2). Synthesis of Al-doped ZnO was carried out via the sol-gel method, which involves mixing and heating at 65°C, followed by degradation at 150°C. TiO2 and ZnO: Al composites were formed using the sonication method at 45°C for 60 minutes. This study evaluates the impact of dyes on the growth of TiO2 and ZnO: Al composites and examines their characteristics - including UV-Vis, band gap, current versus voltage curves, DSSC efficiency-using EDX, and FTIR analyses of solar cells. The DSSC efficiency testing utilizes a photon light source from a halogen lamp with an intensity of 328-580 lux. The results showed that DSSC based on TiO2–ZnO: Al + chlorophyll produced an efficiency of 13.3%, while porphyrin (2:2:0.1) and (2:2:0.2) produced an efficiency of 8.9% and 13.9%, respectively. In conclusion, this study shows that adding dye to the TiO2–ZnO: Al composite significantly improves DSSC performance and shows optimal characteristics. The highest DSSC efficiency of 13.9% underscores the interdependence of absorber layer quality with photovoltaic performance, providing valuable insights for future solar cell design and optimization.
Adsorption Behavior of Chitosan-MWCNTs Nanocomposite for the Elimination of Ofloxacin Medication
Authors: Khudair Zainab Jasim , Kadam Zeina Mohammad
Published: July 2024

A nanocomposite of chitosan and poly acrylic acid grafting multi-walled carbon nanotubes p(CS-co-AA)/MWCNTs was produced using free radical polymerization to study its efficiency in eliminating the antibiotic ofloxacin (OFL) from aqueous solutions. The synthesized nanocomposite material has undergone characterization using FTIR, XRD, FESEM, TEM, EDX, and Zeta potential techniques. The adsorption of OFL on the p(CS-co-AA)/MWCNTs has been evaluated using three established Langmuir, Freundlich, and Temkin isotherm models. The isotherm constant (KF) of 0.218 and the separation factor (R2) of 0.956 indicate strong and desirable adsorption of OFL on p(CS-co-AA)/MWCNTs with a concentration of 100 mg/L at a temperature of 293K and an acidic medium with a pH of 7.0. The primary cause of the reduction in OFL adsorption and dehydrogenation is the increase in pH level. The Van't Hoff equation indicates that the OFL adsorption process exhibits fast kinetics, as seen by a negative thermodynamic parameter ΔH of -0.012 kJ/mol. The pseudo-second-order kinetic model (R2= 1.00) confirms this observation. The results indicate that the synthesized nanocomposite can effectively remove OFL from polluted aqueous solutions.

Authors: Mahmoudi Abdelghani , Van Schepdael Ann
Published: July 2024

New spectrophotometric methods have been developed for the determination of josamycin in pure and dosage forms based on charge transfer reactions. Method-A was based on the complexation reaction of 1,2-naphthoquinone-4-sulphonate with josamycin. Complex absorbance was measured at 454 nm. Method-B was developed by the charge transfer reaction of the amino group of josamycin with menadione. The formed orange products showed maximum absorbance at 458 nm. Lambert Beer’s law was obeyed in the range of 1.0–28.8 μg/mL. The regression plots showed good linearity with determination coefficients of 0.9997. Molar absorptivity and Sandell’s sensitivity were calculated, with a detection limit (LOD) down to 0.28 μg/mL and quantification limits (LOQ) of 0.85–0.89 μg/mL. The validity of procedures was tested for accuracy, precision, recovery and interference and the results were in accordance with ICH guidelines, with relative standard deviation (RSD %) values less than 5.0%. Determination results of josamycin in marketed formulations were in good agreement with the labelled quantities and without any interference from excipients, indicating that they can be used for quality control purposes.

Authors: Vicol Crina , Sârghi Alexandra , Fifere Adrian , Duca Gheorghe
Published: July 2024

The intricate dynamics of antioxidant interactions holds promise for innovating formulations to reduce patient antioxidants doses and prolong efficacy, these aspects being also important for other industrial applications, such as food preservation. In this context, the study presents data on the antioxidant interaction between ascorbic (AA) and dihydroxyfumaric acids (DHF) determined via DPPH method, by applying EPR spectroscopy. Two calculations methods used demonstrated strong and moderate synergistic effects, with antioxidant interaction parameter (AI) of 1.24 and 0.9, respectively. The type of antioxidant interaction is dependent on the concentration ratio of the ascorbic and dihydroxyfumaric acids, thus, at the mM DHF/mM AA ratios of 1.4 and 1.7 the highest synergistic effects with AI of 1.24 have been noticed, but at the mM DHF/mM AA ratio of 1 – an antagonistic effect with AI of 0.93 was registered.

Published: July 2024

Activated carbons have great applicability in the conditioning of wines: discoloration, removal of foreign taste and smell, correction of organoleptic parameters, etc. The purpose of this work was to compare the structural and sorption characteristics of local vegetal activated carbon obtained from apricot stones (AC-C, Republic of Moldova) with that of commercial activated carbons (Granucol® BI/GE/FA, Germany). The physico-chemical characteristics of studied activated carbons have been evaluated by standard methods (nitrogen sorption isotherms, IR spectroscopy, pH value of activated carbons suspension etc.) and the adsorption capacity by using methylene blue dye as a reference substance. Experimental data were analysed by theoretical models: Langmuir and Equilibrium isotherm models, and pseudo-first-order, and pseudo-second-order kinetic models. The adsorption capacity of the local activated carbon (AC-C, 690 mg/g) is higher by 30% than that of activated carbons from Granucol® series (approx. 535 mg/g).
Problems of personnel training in higher education system and ways to solve them
Authors: Alexandrov Aleksandr Yu. ,   Kovrov State Technological Academy of Degtyarev
Published: July 2024

The problematic issues raised in the article are common in the training of engineering and technical personnel of our country. The source of all the problems is the Bologna system of higher education imposed on us — essentially a system of services, not education. At the same time, the pain points that have arisen in the training of specialists related to the organization and implementation of the educational process in universities are derivative and secondary. The most vulnerable pain point — derived from the system of services and business in education — is regulatory per capita financing. In turn, this type of financing has created other problems in the education system. They are especially relevant now in the training of personnel for our military-industrial complex. The problems are most clearly manifested in the regional university. Of course, they are smoothed out to some extent when the university is surrounded by city-forming defense enterprises and good interaction with them. However, with all this, these problems remain very significant. Along with the positive aspects in the work on personnel training, the article examines the factors of the negative impact of regulatory per capita financing on the educational process, as well as some other problems that arise when training specialists for the military-industrial complex. The ways of their solution are proposed. The experience of interaction of the Department of Mechanical Engineering of the Kovrov State Technological Academy of Degtyarev with defense industry enterprises in the training of personnel in the specialty “Small arms, cannon, artillery and rocket weapons” is systematized.

Published: July 2024

The article discusses the issues of improving the quality of training of personnel with higher education who have competencies of such a level that will allow them to ensure the technological sovereignty of the state, including in a dynamically changing labor market. Adjustments to the current legislation in the field of higher education and the labor market in order to improve educational programs of higher education (OOP HE), as well as the harmonization of educational and professional qualifications. Ensuring effective interaction between developers of educational standards (federal educational and methodological associations of higher education — FGOS HE) and professional standards (councils for professional qualifications in economic sectors — SEC), as well as training on their basis of OOP HE. The significance of Federal Law No. 144-ФЗ dated 26.05.2021, in terms of the development and implementation of the OOP HE, and the creation of the necessary legal conditions for the development of a new generation of the Federal State Educational Standard. It is emphasized that the introduction of these changes contributed to reducing the severity of the problem of ensuring the interface of educational and professional standards and removing certain disagreements when updating the Federal State Educational Standard, taking into account professional standards. But the main task of harmonizing the requirements of the labor market for the qualifications of specialists and the competencies of graduates remains unresolved. Therefore, a positive example of interaction between universities and employers’ organizations to resolve controversial issues is presented, as well as the approaches of the SEC of the UP to use on the basis of a systematic analysis of all available capabilities of the relevant Federal State Educational Standard in the formation of the OOP IN.
On the problem of staffing national technological sovereignty
Authors: Reznik Sergey V. ,   Bauman Moscow State Technical University
Published: July 2024

The issues of training specialists with higher technical education are considered in the light of the need to achieve national technological sovereignty. Russia’s withdrawal from the Bologna system initiated another reform of higher education. The content, forms and duration of education are being reviewed, and ways to reform technical universities are being discussed. In this paper, a comparative analysis of three models of technical universities is carried out — research, entrepreneurial and full innovation cycle. Possible changes in the setting of training sessions, the position of students and teachers are highlighted. It is noted that it is necessary to preserve the experience of domestic engineering education and a balanced attitude to the reform of universities in order to exclude a critical decline in the role of scientific schools and departments. The subjectivity of universities, as well as the loyalty of students and staff, will primarily be determined by the presence of advanced scientific schools, outstanding scientists, and not only the state of the campus and the commercialization of research and development results. The significant difference between the tasks facing departments and scientific and educational centers in personnel training is shown. Scientific and educational centers are aimed at research and development, and the educational process in them is of a secondary nature. In the vast majority of scientific and educational centers, do not have high-class working scientists in their composition, and the further they are from the departments, the less chance they have to create advanced scientific and technical products. In this regard, the fascination with clustering and the creation of research and educational centers independent of departments at universities from the standpoint of achieving genuine technological sovereignty is futile.

Balancing Well-being and Social Harmony. An Interdisciplinary Educational Approach
Authors: Ciferri Alberto , Bongianni Cinzia
Published: July 2024

This article reviews the finalities and the methodology of a multidisciplinary educational course designed for students at the high school level. The course can be included in the conventional curricula of public or private schools or used for educational conferences by municipalities. The course is not based on conventional disciplines but rather on socio-economic indicators, which have been recently considered for a classification of the development of various countries. In particular, the course focuses on two indicators “social harmony” and “well-being” that are regarded as the most relevant indices of the quality of life. A brief assessment of cognitive science, relevant to the definition of the indicators, is included.The introduction of elements of real life into educational curricula was pioneered by early educators. The lack of a balance between economic well-being and social harmony appears a primary factor in the conflicts prevailing in the world. It is expected that the introduction elements of real life in current curricula might promote a more balanced society, and also stimulate the development of an interdisciplinary socio-economic discipline.
In Search for Soviet Philosophy of Consciousness. A Review on: Soviet Philosophy of Mind: Etudes on History of Ideas. Ed. by A.D. Maydanskiy. Moscow: Kanon+ROOI “Reabilitatsiya”, 2023. 336 p.
Authors: Pavlov Alexey ,   RAS Institute of Philosophy
Published: July 2024

This text is a review of the collective monograph «Soviet Philosophy of Mind: Etudes on History of Ideas» edited by A.D. Maydanskiy. It is highly improbable that someone will dispute that philosophy of mind is the central (if not main) discipline of contemporary analytic philosophy. Of great importance was identifying the parallels between discussions in analytic philosophy and in what was going on at that time in the Soviet thought which largely existed in the framework of the Marxist-Leninist discourse. The name of the monograph in question suggests that it’s the first systematical historical and philosophical research dedicated to these discussions in Soviet philosophy that to some extent relate to the problems of the philosophy of mind. If our preliminary impression of the book is true, this work has been awaited for a long time. However, the monograph leaves an ambiguous impression. On the one hand, the book tries to fill the gap in the review of the problems of the Soviet philosophy of mind. The «Addendum» contains unique sources (the abstract of Merab Mamardashvili’s Ph.D. thesis, the review of Evald Ilyenkov’s official opponent, etc.), and as a result, the scientific value of the monograph is beyond doubt. On the other hand, there is a clear lack of elaboration of the research methodology. The book tries to convince us that it is arguing with the analytic philosophy of mind but it doesn’t do its job. The reader will unlikely to have a clear understanding of how the Soviet philosophy of mind differs from its Anglo-American alternative: if this kind of comparative analysis took place as one of the goals of the research then it should have been carried out explicitly and systematically. The achievement of this goal is also not facilitated by the lack of consistency in the use of the term «mind»: in different places and without preliminary explanations it is understood either as a phenomenon of nature or as a certain social construct. Among the shortcomings of a different kind, one should point out the incompleteness of the historical and philosophical review.

Accumulated reserves hold back age-related neural compensation in speech-in-noise perception
Authors: Alain Claude , Zhang Lei , Ross Bernhard , Du Yi
Published: July 2024

Recruitment of neural activity or functional connectivity is commonly observed in older adults but poorly understood. We measured brain activity with fMRI during speech-in-noise tasks and assessed whether accumulated reserve accrued through musical training bolsters or holds back age-related neural compensation. Older musicians exhibited less upregulation of task-induced functional connectivity than older non-musicians in dorsal regions, which predicted better behavioral performance in older musicians. The findings suggest that accumulated reserve may hold back neural recruitment. Besides functional connectivity strength, we also found that older musicians showed more youth-like fine spatial patterns of functional connectivity than older non-musicians. However, benefits from visual lip movements were not specific to either hypothesis. Aligning with enhanced benefits in behavioral performance, older musicians showed more extensive functional connectivity enhancement, specifically in the right hemisphere, than older non-musicians. Our findings enlightened the intricate interplay between accumulated reserve and age-related neural compensation during speech in noise perception.
MHD Run-up Flow between Parallel Plates in the Presence of a Transverse Magnetic Field with Dynamic Wall Slip
Authors: Jha Basant K. , Yusuf K. L , Jibril H.M.
Published: July 2024

In this study, we investigate the impact of a uniform transverse magnetic field on the flow between parallel plates. We analyze both impulsive and uniformly accelerated motion of the lower plate in an open circuit system. The magnetic lines of force are assumed to be fixed either relative to the fluid (MFFRF) or fixed relative to the moving lower plate (MFFRP). The Laplace transform technique is employed to obtain the velocity field and skin friction. The obtained solutions are then inverted back into the time domain using a numerical inversion technique based on the Riemann-sum approximation. The results reveal that slip relaxation time affects velocity differently for impulsive versus accelerated motion. This research contributes to our understanding of magnetohydrodynamic (MHD) flow dynamics, with potential applications in aerospace engineering and material processing.

Authors: KINGA OSEMEK , LESZEK KRAKOWSKI , PIOTR BRODZKI
Published: July 2024

The aim of this review was to present different techniques for examining semen and improving its quality. High quality of semen is a critical factor for successful mating and artificial insemination. There are many traditional methods of examining semen, which were used for decades in the 20th century to select the most valuable males. Parameters such as spermatozoa motility, concentration and morphology were examined with the microscope. More advanced methods included Computer-Assisted Sperm Analysis, flow cytometry and Motile Sperm Organelle Morphology Examination. Today, however, examination alone is not enough. The aim is to improve the quality of semen and thus increase pregnancy rates. This review focuses on innovative techniques of selecting spermatozoa, primarily the non-standard and uncommon nanotechnology. This novel, but relatively easy, method makes it possible to selectively purify semen of apoptotic sperm cells and improve the vitality of sperm cells by antioxidative activity, as well as to sort spermatozoa X and Y.
Animals in the legal codes of the countries of the Ancient Near East - Assyria and the Hittite state
Authors: MAŁYSZEK AGATA , JANECZEK MACIEJ
Published: July 2024

In the ancient countries of Mesopotamia, animals were subject to many legal regulations. These regulations applied to domestic animals, such as cattle, sheep, goats, horses, pigs, dogs and bees. They concerned animal trade and rental animals, the seizure of animals, compensation for bodily injury to animals and various legal sanctions related to the coexistence of animals and humans. Legal records also include evidence of veterinary procedures performed on animals, such as castration of males. The authors analyze legal records from the Hittite Empire and Assyria of the Middle Assyrian period. The codes also contain first regulations aimed at animal protection. Hittite law codifies sexual intercourse between humans and animals.

Pregabalin is the active ingredient of drugs used to treat neurosis, anxiety disorders, neuropathic pain. Due to severe stress, caused by genetic factors but mainly lifestyle, many patients currently suffer from anxiety disorders, and increasingly they are turning to this type of medication. Pregabalin taken in an uncontrolled manner can cause adverse side effects, and indirectly even lead to death. Pregabalin is also used in cats to alleviate anxiety and fear associated with veterinary visits and transport. Administered as an oral solution about 1.5 hours before a scheduled trip, it significantly reduces this anxiety. It is also used to reduce pain in dogs undergoing surgery and for the treatment of neuropathic pain. The purpose of this study was to investigate the effect of pregabalin on the length of the life cycle of Lucilia sericata (Meigen, 1826) (Diptera: Calliphoridae). A culture was carried out on a meat medium in the form of a dead laboratory mouse. Observations were carried out using different doses of the active substance (administered orally to the mice): 100 mg/kg (dose 1), 200 mg/kg (dose 2) and 300 mg/kg (dose 3). A control sample (without the drug) was used for comparison. The results showed that pregabalin prolonged the life cycle of the fly relative to the control without the addition of the drug. In addition, it caused a decrease in the body weight of the larvae and pupae and increased their mortality relative to the control sample. By contributing to an understanding of the mechanism of bioaccumulation, this type of study provides valuable information for more accurate estimation of the time of death.

Toxoplasmosis, caused by Toxoplasma gondii, is a parasitic zoonosis of crucial medical and veterinary importance. It is diagnosed mainly by serological methods, which are insufficiently sensitive. It is therefore necessary to rely on the direct detection of the parasite. The present study aimed at the direct detection of T. gondii DNA in placenta fragments by PCR targeting the B1 gene of the parasite. In addition, we identified possible risk factors for infection. The study was carried out on 25 goat farms between 2019 and 2020 in four regions of the Tebessa province in northeastern Algeria and involved 503 goats that had aborted. T. gondii DNA was detected in 30.41% of goat placenta samples (CI: [27.12-41.53]). The on-farm molecular prevalence was 60% (CI: [53.32-72.53]). The molecular prevalence of toxoplasmosis was higher for primiparous females (53.2%) than it was for multiparous ones (15.2%) (p = 0.0001). Likewise, the level of contamination was high in farms with a sedentary management system (36.4%); this system tended to increase the prevalence of toxoplasmosis (P = 0.008). In addition, it appears that the stage of gestation, history of abortion, and season had a significant effect (p < 0.05) on the prevalence of the disease. To conclude, this study revealed that goats included in this experiment were heavily infected with T. gondii, which represents a major risk for consumers in the Tebessa region. Further research is needed to improve our knowledge of the different genotypes of T. gondii infecting populations of small ruminants.

Published: July 2024

In 2013, the Polish Federation of Cattle Breeders and Dairy Farmers introduced a new service – identifying cows in a state of subclinical ketosis (SK). Based on the content of ketone bodies in milk, i.e. β-hydroxybutyrate and acetone determined in a milk sample taken on the day of the trial milking, cows that were probably in the SK state on the test day are identified using a logistic regression model. Such cows are indicated to breeders in the reports from milk recording. The aim of the study was to analyze the incidence of SK in the recorded population. During 10 years of SK monitoring, the incidence of SK in cows decreased with each subsequent year. SK occurred more often in cows with lower milk yield and in smaller herds. The results indicate a constant improvement in the health situation of recorded cows in Poland, in the context of the incidence of SK.

Bu bağlamda, daha önce herhangi bir çalışmaya konu olmayan Bursa Mudanya Halil Ağa (Eski) Camisi ve haziresindeki mezar taşları ayrıntılı bir şekilde ele alınmıştır. Halk arasında Eski Cami olarak da bilinen Halil Ağa (Eski) Camisi, plan, düzenleme ve süsleme bakımından mütevazı bir mahalle camisidir. İlk inşa tarihi kesin olarak bilinmeyen yapı, taçkapısının üzerindeki onarım kitabesine göre, Kethüda Halil Ağa tarafından 1643-44 tarihinde onarılmıştır. Yapının ilk inşa tarihi ve banisi vakıf kayıtları, arşiv belgeleri ve yapının haziresindeki mezar taşı sayesinde tespit edilmiştir. Caminin haziresinde sekiz mezar yer almaktadır. Hazirede, caminin banisine ait mezar taşının yanı sıra ulema-ı kuzattan yüksek rütbeli kadı, müderris, molla gibi kentte görev yapmış kişilerle onların yakınlarına ait mezar taşları da yer almaktadır.

Recent studies have mainly relied on radar technology for extracting crucial vital signs because of its ability to measure without physical contact. The focus on deriving cardiac interbeat interval and heart rate variability has gained significance due to its complexity and relevance in healthcare. Our investigation involved a detailed analysis of continuous wave radar signals to enhance the extraction of chest wall movement data. Using a convolution algorithm, we eliminated the respiratory component from the signal, while a locally projective noise reduction algorithm helped isolate the heartbeat component. Subsequently, a derivation filter was applied to pinpoint the R peak of the heartbeat, facilitating the collection of IBI and HRV metrics. This methodology proved effective for individuals in a relaxed, motionless state. However, its efficacy in cases of elevated heart rates caused by factors such as exercise or caffeine consumption remained uncertain. For subjects with large changes in heart rate followed by large changes in cardiac IBI, we made a small improvement in the algorithm. By performing a window shift of 10 seconds with an overlap of 1 second. Each 10-second data segment is fed into the algorithm. At each data segment, we perform multiple iterations with decreasing number of neighbors until no further change is made. With this adjustment, the results achieved in the group of subjects using input stimulation to increase heart rate such as exercise, or drinking coffee were indicated a strong correlation of 96.38% between radar-based measurements and reference measurements for this group of subjects, affirming the effectiveness of the proposed method in such scenarios.

Kişilerarası iletişimi sağlayan dil, aşamalı bir yapıya sahip karmaşık bir dizgedir. Bu özelliğiyle karşılıklı iletişimi sağlamanın yanı sıra ve ötesinde pek çok, özellikle de toplumsal bazı işlevleri yerine getirmektedir. Bu dizge içerisinde yer alan argo, her dilde görülen ve toplum içindeki bir kesimin farklı biçimde anlaşma sağlamak amacıyla oluşturduğu özel bir alt dizge durumundadır. Argo sözcüklerin oluşumunda sıklıkla eğretilemelerden yararlanıldığı görülmektedir. Eğretileme, iki kavram arasında ilişki kurma ve bir kavrama ilişkin özellikleri kullanarak başka bir kavramı anlatma işlevini gören bir tür anlambilimsel aktarım olarak kabul edilmektdir. Argolardaki eğretilemelerde kadın ve erkek ikili karşıtlığını vurgulayan sözcüklerin belirgin biçimde kullanıldığı gözlemlenmiştir. Bu noktadan hareketle, bu çalışmada argoda kadın ve erkek eğretilemelerinin gönderimleri nitel araştırma yöntemi ile incelenmiştir. Çalışmanın bütüncesi Türkçenin en kapsamlı argo dağarcığı olduğu düşünülen Türkçenin Büyük Argo Sözlüğü (Tanıklarıyla)’nden derlenmiştir. Erkek ve kadın kavramlarına gönderimde bulunan sözcüklerin hangi kaynak alanlardan aktarıldığına ilişkin bulgular karşılaştırılarak toplumsal cinsiyet bağlamında yorumlanmıştır. Buna göre, Türk argosunda yer alan sözcüklerdeki eğretilemelerde erkek için daha olumlu kavramlarla ilişki kurulurken, kadının daha olumsuz kavram alanlarıyla ilişkilendirildiği saptanmıştır.

Bu araştırmanın amacı, Türkiye’de çalışma ekonomisi ve endüstri ilişkileri konusunda 2021 yılında tamamlanan lisansüstü tezlerin araştırma yöntemi, veri toplama yöntemi ve kullanılan veri türü ile analiz yöntemleri kapsamında incelenmesidir. Araştırmada nitel araştırma yöntemi seçilmiş, veri toplama yöntemi olarak doküman analizi yöntemiyle YÖK Ulusal Tez Merkezi Veri Tabanından (YÖKTEZ) elde edilen 146 adet lisansüstü tez belirlenmiştir. Elde edilen veriler tanımlayıcı istatistiki veriler kullanılarak içerik analizi ile incelenmiştir. Elde edilen bulgular sonucunda 2021 yılında 25 üniversitenin sosyal bilimler enstitülerinde çalışma ekonomisi ve endüstri ilişkileri anabilim dalında 42 doktora tezi ve 104 yüksek lisans tezi olmak üzere toplam 146 lisansüstü tezin tamamlandığı, tezlerden 7'sinde karma yöntem, 15'inde nicel araştırma yöntemi ve 124'ünde ise nitel araştırma yönteminin kullanıldığı, araştırmada en sık kullanılan veri toplama yönteminin %32,88 oranla görüşme/mülakat yönteminin olduğu ve verilerin, en sık analiz edildiği yöntem olarak %45,89 kullanım oranıyla içerik analizi olduğu tespitlerine yer verilmiştir. Örneklemin 2021 yılı çalışma ekonomisi ve endüstri ilişkileri ana bilim dalında tamamlanan lisansüstü tez çalışmalarından YÖKTEZ’de yayınlanmasına izin verilenlerin kullanılması araştırmamın sınırlılıklarıdır. Diğer alanlarda yoğun olarak çalışılmış olmasına rağmen çalışma ekonomisi ve endüstri ilişkileri kapsamında sınırlı sayıda çalışma bulunmaktadır. Alandaki en son araştırma 2020 yılında yapıldığından, akademik çalışmalara ve lisansüstü eğitime sağladığı katkılar çalışmamızın eşsiz değerini oluşturmaktadır.

The performance of students in argumentative writing has not yet met the required standards. This issue stems from the fact that educational activities are not centered around students, and the instructional methods used by lecturers are not suitable, leading to poor results in students' argumentative writing. To enhance these skills, it is essential to adopt an effective instructional model, specifically the prediction, observation, explanations, elaboration, writing, and evaluation (POE2WE) model. This study aims to investigate the impact of the POE2WE model and critical thinking on the argumentative writing skills of students at Indraprastha PGRI University. An experimental approach is utilized, employing a 2 x 2 factorial design to analyze data with SPSS software. The findings indicate that high critical thinking skills are crucial for argumentative writing, regardless of whether the POE2WE or Discovery Learning model is used. Both learning models and critical thinking significantly affect argumentative writing skills. The POE2WE model is particularly beneficial for students with lower critical thinking skills, while the Discovery Learning model suits those with higher critical thinking skills better. Learning models serve as frameworks that lecturers use to create effective learning environments.
