Beyond The Domestic Space: The Beauty Of Women In Hijab In The Commercials
Authors: Qudratullah  , Abd Malik Ikmal
Published: July 2024

In advertisements, women are close to the role of models of the products offered. It is because women are considered to have many attractions. This article explores the meaning of the beauty of women wearing the hijab in the Wardah cosmetic advertisement version "Kisah di Balik Cantik: Awal Mimpi ."This advertisement highlights the stories of individual journeys and struggles to achieve authentic and meaningful beauty. This advertisement not only explores the physical aspects of beauty but also promotes messages about beauty that come from within  as well as  motivates personal stories. This can help change the narrow narrative of hijab-wearing women's beauty in the media.  This advertisement features a short story that includes the ability and competence to represent the beauty of women wearing the hijab in making decisions about products, jobs, and partners. This study uses a qualitative approach and Roland Barthes' semiotic as a tool of  analysis. The results of this study indicate that the beauty of women in hijab contains three elements: halal, reasonable, and not excessive. Beauty comes from within, behaves gently, and independently dares to get challenges and work outside the domestic sphere.[Dalam  iklan, perempuan sangat dekat dengan peran model dengan beragam produk yang ditawarkan. Hal ini dikarenakan wanita dianggap memiliki kelebihan dan daya tarik yang banyak dikagumi. Artikel  ini bertujuan untuk menggali makna kecantikan wanita berhijab dalam iklan kosmetik Wardah versi “Kisah di Balik Cantik: Awal Mimpi”. Iklan ini menyoroti cerita perjalanan dan perjuangan individu untuk meraih kecantikan yang autentik dan bermakna. Iklan ini tidak hanya mengeksplorasi aspek fisik kecantikan, tetapi juga mempromosikan pesan tentang kecantikan yang berasal dari dalam dan cerita-cerita pribadi yang memotivasi. Hal ini dapat membantu mengubah narasi yang terkadang sempit tentang kecantikan wanita berhijab dalam media.  Iklan ini menampilkan cerita singkat yang memuat kemampuan dan kompetensi dalam representasi kecantikan perempuan berhijab dalam memilih aspek mengambil keputusan tentang produk, pekerjaan dan pasangan. Penelitian ini menggunakan pendekatan kualitatif  dan semiotika Roland Barthes  sebagai alat analisis. Hasil penelitian ini menunjukkan bahwa kecantikan wanita berhijab mengandung tiga unsur yaitu halal, baik, dan tidak berlebihan. Kecantikan datang dari dalam, berperilaku lembut, dan secara mandiri berani  mengambil tantangan  serta  bekerja di luar ranah domestik]

Caracterización de las directrices éticas, legales y sociales para la conformación de un biobanco de investigación en el Ecuador, desde la perspectiva de los principios de confidencialidad, dignidad y autonomía. Una revision sistemática
Authors: Nuñez Vaca Evelyn Cristina
Published: July 2024

Se realizó una revisión sistemática para conocer las implicaciones éticas, legales y sociales de la creación de un biobanco de investigación desde la perspectiva de los principios de confidencialidad, dignidad y autonomía, con la finalidad de aplicarla a la creación de un biobanco de investigación en el Ecuador.
Se incluyeron todos aquellos artículos conteniendo los términos (DECS/MESH): “biobancos de investigación” y “ética”, “dignidad”, “autonomía”, “confidencialidad” y “cuestiones éticas, legales y sociales”. Entre enero del 2021 y mayo del 2022, se hizo uso de los motores de búsqueda Pubmed, Science Direct, Scielo y Google académico; incluyendo los artículos redactados en inglés, portugués y español de los últimos diez años.
Se analizaron 85 artículos con temas relevantes para los objetivos de la investigación. De estos, solo el 1% correspondió a América Latina, siendo Colombia, Brasil y México los países que más contribuyeron.
A pesar de que no se ha llegado a un consenso a nivel mundial sobre las directrices éticas, legales y de gobernanza de los biobancos de investigación en seres humanos, el camino para la estandarización de dichos procesos se debe fundamentar en el entrenamiento de los investigadores, la capacitación continua de los pacientes y la creación de marcos comunes de gobernanza local e internacional. Se comprobó que la ética principialista, específicamente los principios de confidencialidad, dignidad y autonomía forman parte del marco ético, legal y social de los biobancos de investigación en seres humanos.

Rehumanizar nuestro mundo
Authors: Salmerón Ángel
Published: July 2024

La crisis global de nuestro mundo, provocada por la violencia de las guerras y las pandemias, está poniendo de manifiesto la necesidad que tenemos los seres humanos no sólo de mejorar nuestras ciencias sino también de mejorar como personas. Aunque la deshumanización no es algo nuevo -y todos sabemos la que larga crisis de sentido que arrastra la Humanidad desde el siglo XIX- también es cierto que la crisis actual nos urge la puesta en práctica de una rehumanización. Como sugieren los autores de esta original monografía, se trata de apostar por unas ciencias de la persona que nos ayuden a ser auténticamente humanos. La utopía de un mundo nuevo rehumanizado quizás no es visible todavía, pero es un deber intentarlo porque los tiempos presentes, no más ni menos fáciles ni difíciles que otros, ciertamente tes, están acelerado una Historia deshumanizada. Lo importante ahora es que esta utopía, como diría Ernst Bloch, no sea abstracta o teórica, sino concreta y práctica. “Rehumanizar nuestro tracta mundo” justamente apunta a hacer visible la concreción de este ideal desde temáticas diferentes pero desde ópticas comunes, y así, como propone el profesor José Luis Cañas en su reciente obra Rehumanización, Un mundo más humano es posible te (Ed. Universo de Letras/Planeta), poder transformar de verdad nuestras sociedades.
Exploration of Pilobolus sp. Fungi from Various Livestock Manures in Kedung Pacul Village, Klaten
Authors: Mahardhika Wahyu Aji , Akmaliyah Rizna , Diana Milsa Solva , Listyowati Sri
Published: July 2024

Pilobolus is a coprophilous fungus belonging to the Zygomycota. Pilobolus sp. is called a coprophilous fungus because it can live in animal feces. The uniqueness of this fungus is that it can shoot its spores, so Pilobolus sp. is called a shotgun fungus. Pilobolus sp. exhibits a phototropism mechanism in which the sporangium shoots spores in the direction of light. Pilobolus has a unique living habitat, namely in the manure of herbivores such as cows, goats, sheep, etc. This habit of life may seem terrible to us, but fungi like Pilobolus sp. are very important in life because they are a type of decomposer, capable of breaking down organic matter from dead living things. So the purpose of this study was to observe the spores produced by the fungus Pilobolus sp.  (a fungus in animal waste). The method used was to cultivate the fungus Pilobolus sp. for seven days on various animal wastes placed in jam bottles. The results showed that the Pilobolus sp. fungus grew on various media of animal feces, such as horses, cows, goats, and pigs, with different growth times, and there were also spores shot on the glass walls that had been perforated.

Recast frequency and the acquisition of English articles in a computer-mediated context
Authors: Sarandi Hedayat , Nassaji Hossein
Published: July 2024

This study examines the role of recast frequency and its effectiveness in the acquisition of English articles in a computer-mediated context. Sixty-one pre-intermediate university language learners in Turkey were randomly divided into four main groups: high frequency recast (HF), low frequency recast (LF), test control, and task control groups. The learners in the HF and LF recast groups completed five and two tasks, respectively, in a video-conferencing environment and received oral recasts on their incorrect use of English articles. Learners in the test control group only took the pre and posttests, and learners in the task control group completed five tasks without receiving feedback on the target structure. The outcome was measured through online picture description and error correction tasks. Findings showed that in the picture description task, learners in the HF group performed significantly better than those in the LF recast group and the control groups. In the error correction task, the results revealed a short-term advantage for learners in the HF group, which faded away in the delayed posttest. Significant correlations were also found between the recast frequency and learners’ score improvement in the immediate and delayed picture description tasks but not in the error correction tasks. These results suggest that recast quantity may play an important role in improving learners’ accuracy of their oral production.
Exploring the psychometric properties of the Grammar Learning Strategy Inventory in the Chinese EFL context
Authors: Wang Yongliang , Derakhshan Ali , Pawlak Mirosław , Mehdizadeh Mostafa
Published: July 2024

Learning a second language is a life-long process requiring acquaintance with a repertoire of language learning strategies (LLS). Despite copious research on LLS and their role in fostering autonomous learning, few studies have examined strategies employed when trying to master specific subsystems of the target language, especially grammar. Meaningful communication in a second language hinges on implicit or highly automatized grammar knowledge, which, given the limitations of classroom-based grammar instruction, must for the most part be developed by learners themselves outside the classroom and this can best be achieved through adept use of grammar learning strategies (GLS). Our knowledge of the GLS, however, is scant, an issue that can be addressed either by designing reliable GLS measurement instruments or revalidating the few existing ones. This study adopts the latter approach by investigating the psychometric properties of Pawlak’s (2018) Grammar Learning Strategy Inventory (GLSI) in the Chinese context. The tool was administered to 923 English majors, and the responses were subjected to exploratory and confirmatory factor analyses. We found that all seven strategy categories included in the original instrument showed acceptable composite reliability and discriminant validity. The paper concludes by suggesting further revalidation of the GLSI and proposing avenues of research that employ methodological innovations to shed further light on GLS.
PROPOSING A MODEL FOR UNDERSTANDING BLOCKCHAIN TECHNOLOGY ADOPTION IN ORGANIZATIONS
Authors: Gürbüz Fatma Gülruh , Aljamal Maryam
Published: July 2024

Blockchain technology was first introduced in 2008, and since then it has been a subject of interest for both academicians and practitioners. Blockchain has many applications in business areas, such as: cryptocurrency, health information systems, electronic notary, supply chain management, human resources management, music industry, real estate management and much more. Despite the growing interest in blockchain technology, the literature regarding it is relatively new and limited. In the context of technology adoption studies, especially in blockchain field, there are limited number of studies that investigate innovation adoption at the organizational level. This paper proposes a model that integrates diffusion of innovation theory, technology-organization-environment framework, and institutional theory for future blockchain adoption studies at the organizational level.
The Contemporary Significance of Gibran’s Literary Works
Authors: Li Pei
Published: July 2024

The Lebanese writer Gibran Khalil Gibran was one of the pioneers of modern Arab literature and the “standard-bearer, soul and leader” of the writers of the “Mehjar” literature who played an important role in the revival of Arabic literature. He is a world-renowned cultural celebrity who has had a great influence in both Arabia and the West. Based on the theory of literary interpretation, this paper explores the commonality between Gibran’s thought and contemporary social values, which are embodied in four aspects: ecological view, women’s emancipation thought, East-West relationship view, and human unity consciousness. Gibran’s ideas contain rich humanistic values that transcend their time, and the up-to-date interpretation to them will help us draw valuable insights from them and gain inspiration in the face of the many major challenges of the era of globalization.
The Green Economy Transformation of GCC Countries and China-GCC Cooperation in Green Development
Authors: Huang Chao
Published: July 2024

In 2015, all GCC countries acceded to the Paris Climate Agreement and submitted their Intended Nationally Determined Contributions since 2020. The Russian-Ukrainian conflict in 2022 led to a surge in world oil prices. Meanwhile, the increase in oil revenues created the new impetus for the green economy transformation and pushed it to an accelerated period. The green economy transition aimed at replacing fossil energy with hydrogen energy and making it a new driving force for export trade growth, on the other hand, it will incubate a number of private enterprises in the field of green science and technology, and realize economic diversification and private economy-led growth, and eventually led to economic structural adjustment which can increase the growth rate. GCC governments are committed to building renewable energy infrastructures, developing carbon capture and sequestration technologies, and emphasizing green and low-carbon building environmental governance. However, shortcomings in finance, technology and human resources restricted the transformation. China and the GCC countries need to cooperate to alleviate the difficulties and realize common green development. Currently, bilateral cooperation has already achieved fruitful results in areas of renewable energy infrastructure construction, green transportation and green capacity-building, In the future, green financial cooperation still needs to be strengthened.

Audience-authored paratexts: legitimation of online discourse about Game of Thrones
Authors: Laukkanen Markus
Published: July 2024

With the increasing proliferation of the internet, audience-authored online paratexts continue to gain significance in culture and in the communicative structures of narrative texts. This article takes a critical look at the ways in which Gérard Genette’s concept of paratext (1987) has been used in contemporary scholarship. The article offers a model of online paratexts based on an interdisciplinary understanding of paratextuality and internet-age culture. Ways in which paratexts become legitimate in online environments are considered through the analysis of HBO’s popular TV series Game of Thrones (2011–2019). Legitimation extends from production-authored paratexts to audience-authored paratexts, reflecting changes in the relationship between authors and readers typical to contemporary culture. Finally, the article introduces the concept of paratextual reauthoring, which refers to the practice of canonizing alternative interpretations of texts via the use of online paratexts.
Explaining the innovation dichotomy: the contexts, contents, conflicts, and compromises of innovation stories
Authors: Lemmetty Soila
Published: July 2024

This study describes the narratives of innovation produced in a knowledge-based company, constructs them into core stories and develops a narrative framework suitable for researching the topic. The research data consisted of thematic interviews with 23 professionals from the Finnish technology company. Innovation stories were convoluted, identifying innovation-framing contexts that were related to ownership, drivers, continuity, decisions and values. Based on these narratives, the study generated the 4Co (context, content, conflict, and compromise) analytical framework suitable for examining narrative data in innovation research. The study also produced an ideal description of innovation as a simultaneously shared and personally meaningful evolutionary learning process that takes place in small steps and requires a balance of necessity and freedom as well as decision-making based on intuition and facts, producing human efficiency as a value for employees and the organisation. Based on the findings, scientific, methodological, and practical discussions are also presented.
Oxidative stress-mediated epigenetic remodeling, metastatic progression and cell signaling in cancer
Authors: Phull Abdul-Rehman , Arain Sadia Qamar , Majid Abdul , Fatima Humaira , Ahmed Madiha , Kim Song-Ja
Published: July 2024

Cancer is a serious public health issue and cases are rising at a high rate around the world. Altered production of reactive oxygen species (ROS) causes oxidative stress (OS) which plays a vital role in cancer development by disrupting signaling pathways and genomic integrity in the cellular microenvironment. In this study, we reviewed the regulation of noncoding RNAs, histone modifications, and DNA methylation which OS is involved in. These mechanisms promote cancer growth, metastasis, and resistance to chemotherapeutic agents. There is significant potential to improve patient outcomes through the development of customized medications and interventions that precisely address the role of OS in the onset and progression of cancer. Redox-modulating drugs, antioxidant-based therapies, and measures to restore regular cellular activity and OS-modulated signaling pathways are some examples of these strategies. One other hypothesis rationalizes the cancer-suppressing effect of OS, which acts as a two-edged condition that warns against the use of antioxidants for cancer treatment and management. The present study was executed to review the impact of OS on epigenetic machinery, the evolution of metastatic cancer, and how OS mediates cellular signaling. Along with, insights into the potential of targeting OS-mediated mechanisms for cancer therapy.
Pour une reconnaissance des signes éthiques : les formes de l’ethos et ses implications sociologiques
Authors: Levesque Simon , Bédard Pascale
Published: July 2024

Le concept d’ethos, que l’étymologie rattache à l’éthique, aux mœurs et à la morale, est ici examiné à l’intersection des études sémiotiques et des sciences sociales. Une méthode est développée pour l’étude des caractères, ou ethe, qui passe par la reconnaissance des signes éthiques sur les scènes d’énonciation considérées, elles-mêmes constitutives d’une situation sociale à analyser. L’article est divisé en trois parties. La première partie définit l’ethos selon ses deux usages dans la théorisation aristotélicienne (rhétorique et poétique). La deuxième partie définit les signes éthiques dans leur rapport théorique aux études sémiotiques et à la sociologie. La troisième partie présente une application à un cas contemporain à cette recherche : la controverse dans l’espace public autour d’un projet de développement du territoire dans la ville de Québec. En théorisant pour la première fois les signes éthiques, cet article propose un renouvellement de la sociologie compréhensive au moyen d’une méthodologie éprouvée.
Meaning-making and transformative engagement – notes on Gunther Kress’s social semiotic and multimodal approach to learning
Authors: Selander Staffan
Published: July 2024

Against the background of a longstanding collaboration between Gunther Kress’s research group in London and my own research group in Stockholm, I reflect, in this paper, on the role of Kress’s ideas in our joint development of a social semiotic, multimodal, and design-oriented approach to learning, an approach which sees learning as performative, and as an activity in which learners create their own learning paths. I first discuss how, for Kress, this path has three elements, the affordances of the learning resources available to the learner, the learner’s ‘interest’ which turns aspects of these resources into ‘prompts’ for learning, and the learner’s active interpretation and transformation of these aspects, the results of which can then be recognized and valued as ‘signs of learning’. However, recognizing learning also needs to take account of the dimension of time, so as to make it possible to assess whether learners have gained knowledges and skills they did not have at an earlier stage. I then discuss the role of context in Kress’s thinking about learning. For Kress, context is another vital aspect of a social semiotic theory of learning. On the one hand, Kress focuses here on the specific, unique contexts in which individual learners create their own learning paths. On the other hand, he recognizes that signs will always carry social and political relations. Reflecting on the dynamic relation between individual learners and the way institutions regulate ways of learning, I discuss both the continued role of institutional learning contexts and their hidden curricula, and the way emerging technologies facilitate individual learning paths and interactive, participatory forms of learning.

Published: July 2024

New series of benzimidazole incorporating piperazine moieties in single molecular framework has been reported. The structures of the synthesized derivatives were assigned by 1H-NMR, 13C-NMR, and HR-MS techniques. The hybrid derivatives were evaluated for their acetylcholinesterase and butyrylcholinesterase inhibition effect. All the synthesized analogs showed good to moderate inhibitory effect ranging from IC50 value 0.20 ± 0.01 µM to 0.50 ± 0.10 µM for acetylcholinesterase and from IC50 value 0.25 ± 0.01 µM to 0.70 ± 0.10 µM for butyrylcholinesterase except one that showed least potency with IC50 value 1.05 ± 0.1 µM and 1.20 ± 0.1 µM. The differences in inhibitory potential of synthesized compounds were due to the nature and position of substitution attached to the main ring. Additionally, molecular docking study was carried out for most active in order to explore the binding interactions established by ligand (active compounds) with the active residues of targeted AChE & BuChE enzyme.
A Sense of Stalinism
Authors: Kravtsova Alena , Slade Gavin
Published: July 2024

This article compares visitor experiences at the Gulag History Museum in Moscow and the NKVD Prison Museum in Tomsk, Siberia. The museums differ in the production of authenticity in the museum experience. The Moscow museum has no direct relationship to a site of memory and therefore utilizes constructed forms of authenticity. In contrast, the Tomsk museum makes use of objective authenticity given its location in an original prison building. The museums share a stated mission to produce a cosmopolitan mode of remembering based on universal values and empathy for victims with a preventive mission for the sake of the future. The article examines original data from visitor focus groups to understand the emotional impact of these museums. The Moscow museum manufactures the atmosphere of the Gulag through interactive sensory stimulation. We found that this can meet resistance from visitors who sense that their emotions are being manipulated. We found that the Tomsk museum directly elicits strong emotional responses but responses could also include dark tourist titillation. In conclusion, we consider how these findings speak to debates around the tension between cosmopolitan, antagonistic, and agonistic modes of remembering.

The magnetic, electronic, and structural properties of the cubic phase of lead-doped alloys of praseodymium bismuth compounds with the generic formula PrPbxBi1-x (x = 0, 0.25, 0.50, 0.75, and 1.0) have been reported in this paper by employing the formalism of density functional theory (DFT). For the analysis of physical properties, we have executed the full-potential linearized augmented plane wave plus local orbit (FPLAPW+lo) technique, while the exchange-correlation potentials in the Kohn-Sham equation (KSE) are implemented within the generalized gradient approximation (GGA) extended by the Perdew-Burke-Ernzerhof (PBE) correction. The structural parameters, lattice constants, volume, bulk modulus, pressure derivatives, and energy have been computed with the Wein2k code by fitting total energy through Murnaghan's equation of state. The structural stability of the compounds has been reported from the spin-polarized calculations. The electronic energy bands and total and partial densities of states of the compounds have been calculated in both majority and minority spins, depicting them as metallic. The similar spectrum intensities of the Pr(5d+4f) and (Pb +Bi)2p states account for the majority of the contribution to the density of states near the Fermi energy level. The spin magnetic moments computed for the supercell of the doped compounds have indicated that they are magnetic materials. From the comparison of spin magnetic moments in the PrBi compound, we noticed an improvement in the magnetic moments after doping lead into the PrBi compound.

The current study investigates the complex physical characteristics of DPs Na2AgGaY6 (Y = Cl, Br, I) through the utilization of density functional theory (DFT), thus providing insights into its potential benefits in the fields of optoelectronics and thermal usage. The tolerance factor and Born’s stability criteria are meticulously calculated in order to determine the structural stability of the cubic phase. The calculated direct band gap values for Na2AgGaCl6 and Na2AgGaBr6 ensure maximum absorption in the visible and infrared spectra, respectively. Na2AgGaI6 is the most optimal DP used in photovoltaic devices. An examination has been conducted on the See-beck coefficient, electrical and thermal conductivities, and other essential parameters utilized in the characterization of transport properties. The compounds Na2AgGaI6, Na2AgGaBr6 and Na2AgGaCl6 demonstrate exceptional ZT indices of 0.78, 0.74 and 0.73, accordingly, emphasizing their critical importance in thermoelectric devices.

The N/Cl co-doped TiO2 nanostructures were studied as photocatalyst for rhodamine B (RhB), Methylene Blue (MB), and Methyl Orange (MO) degradation. A Commercial TiO2 (P25) grade was also compared to our materials. The N/Cl co-doped TiO2 at different Ti4+ precursors were synthesized by the co-precipitation method. The structural, surface morphology, and surface area were analyzed by XRD, SEM, TEM, and BET. Optical properties of samples were investigated by UV-visible spectroscopy showing that the N/Cl co-doped TiO2 has smaller bandgap than the P25. Overall, the improved N/Cl co-doped TiO2 samples showed better performance than the P25 for RhB, MB and MO degradations.

In order to promotion the RF performance, a grade In1-xGaxAs channel (G-HEMT) introduced to the AlGaAs/InGaAs HEMT. The G-HEMT with the grade In1-xGaxAs channel forms a deeper potential well and confines more electrons in the channel, results in improving the DC and RF characteristics. Moreover, because of the grade In1-xGaxAs is effectively reduced the peak electric field, and leads to a significant increase in breakdown voltage (BV). Moreover, the G-HEMT also increases resistance to single event effects (SEE). The simulation results indicate that the fmax is significantly increased to 889 GHz of G-HEMT from 616 GHz of conventional AlGaAs/InGaAs HEMT (C-HEMT). The the fT is significantly increased to 521 GHz of G-HEMT from 326 GHz of C-HEMT, as well as the IDsat is increased by 64.8% and the BV increases by 37%. In addition, the SEE peak drain current of G-HEMT is dramatically reduced 51%.

A tungsten oxide load at submonolayer coverage of alumina renders highly dispersed dimeric polytungstate (octahedral and distorted octahedral coordination) and isolated monotungstate (tetrahedral) species. The polytungstate/monotungstate proportion increases when approaching monolayer. Crystalline WO3 nanoparticles emerge at higher loads. All components display hexavalent oxidation; yet, tungsten‐ oxide (W–O–W) and tungsten‐ oxide‐ alumina (W–O–Al) interactions were discerned by X‐ ray photoelectron spectroscopy of the WOx/Al2O3 materials herein prepared with 1, 3, and 5 weight percentages. The 5 wt % sample displayed the highest intensity percentage of W–O–Al species correlated to the highest methanol conversion (45 %), ascribed to the appearance of the weak acidity disclosed by temperature‐ programmed desorption of ammonia.

Corneal blindness affects approximately 8 million people worldwide. The effectiveness of keratoplasty depends on several factors, including surgical technique, clinical characteristics of the patients, and social factors such as their adherence to treatment. Objective — To analyze nonattendance of doctor’s appointments and associated clinical outcomes in Russian patients who underwent high-risk and low-risk penetrating keratoplasty (PKP). Material and Methods — We conducted a retrospective cohort study to analyze the pre- and postoperative records of patients who underwent PKP. The low-risk group included 28 people with keratoconus (their mean age was 33±3 years), while high-risk group included 54 people with corneal opacity of various etiologies (their mean age was 67±13 years). The study assessed adherence to treatment by examining attendance at postoperative physician visits. Successful corneal transplant engraftment was considered favorable outcome, whereas graft failure or opacification was considered adverse outcome. The duration of observation was 12 months. Results — Patients in the low-risk group were twice as likely to attend postoperative appointments compared with patients in the high-risk group (p=0.0001). Patients over 70 years of age showed lower adherence to treatment (p=0.016), while those with higher education had significantly improved appointment attendance (p=0.017). Moreover, poor adherence increased the odds of adverse PKP outcome at 12 months in high-risk patients (OR=4.31; p=0.045). Conclusion — Failure to attend postoperative appointments in the high-risk group was associated with older patient age and lower education level, and correlated with adverse clinical outcome in Russian patients.
Русская женская литература в XVIII–XIX веках: эволюция, проблематика и поэтика

The purpose of this article is to analyze the evolution, problematics and poetics of Russian women’s literature of the 18th and 19th centuries. The main task of the work is to determine the origins of professional women’s writing, as well as to show the development and evolution of this branch of art. The period of women’s creative work that lasted from the second half of the 18th century reached its peak in the 1830s and 1840s, becoming a fruitful stage for women’s literature, which developed in many forms and directions. It should be noted that its formation is inextricably linked with changes in the state system (the accession of women to the Russian throne) and the literary process (for example, the era of sentimentalism), as well as with the emergence of new, purely female, groups and movements (for example, emancipation). The evolution of Russian women’s writing in the eighteenth and nineteenth centuries was all along a process subordinate to the power of men, who had a real influence on the formation of women’s style or publication processes.
Kategoria wroga w dyskursie rosyjskiej władzy (na przykładzie orędzia W. W. Putina z 24 lutego 2022 roku)

The subject of research in this article is the figure of the enemy, which is identified in numerous studies as one of the basic components of the world of propaganda, including communist propaganda. The aim of the analysis is to characterize the language exponents of the category of enemy in V. V. Putin’s message and to indicate their functions in the contemporary discourse of the Russian authorities. It should be emphasized that we treat the discourse of the Russian authorities as modern newspeak, that is, as a contemporary variant of the communist propa ganda discourse used by the political elite of today’s authoritarian Russia. In the examined message, two types of enemies were distinguished: real, i.e. actually existing in the world around us, to which the United States belongs, along with its allies from the North Atlantic Treaty Organization, and invented enemies, i.e. ones that are a kind of creation of Russian propaganda. These created enemies include neo-Nazis allegedly supported by the NATO organization, who supposedly form the current government in Kiev. They are portrayed as posing the most se rious threat to the Russian Federation. The category of enemy serves V. V. Putin for officially explaining to the Russian people the reasons for beginning the socalled “special military operation” in Ukraine, which is supposed to be “self-defence against threats to Russia”.
