Developing Mathematical Communication Skills for Students in Grade 8 in Teaching Congruent Triangle Topics
Authors: Uyen Bui Phuong , Tong Duong Huu , Tram Nguyen Thi Bich
Published: April 2024

Teaching mathematics in general and instructing mathematics at junior schools in particular not only create favorable conditions for students to develop essential and core competencies but also help students enhance mathematical competencies as a foundation for a good study of the subject and promote essential skills for society, in which mathematical communication skill is an important one. This study aimed to train students in mathematics communication by presenting them with topics in line with the structure's congruent triangles. An experimental sample of 40 students in grade 8 at a junior school in Vietnam, in which they were engaged in learning with activities oriented to increase mathematical communication. A research design employing a pre-test, an intervention, and a post-test was implemented to evaluate such a teaching methodology's effectiveness. For assessing how well the students had progressed in mathematical language activities, the gathered data were analyzed quantitatively and qualitatively. Empirical results showed that most students experienced a significant improvement in their mathematical communication skills associated with congruent triangles. Additionally, there were some significant implications and recommendations that were drawn from the research results.
Nubian faience
Authors: Lacovara Peter
Published: April 2024

The complex interactions between Egypt and its Nubian neighbours are reflected in the most telling way in the artefactual materials left by these distinct yet interconnected cultures. One can see this in particular within the medium of what is known as “Egyptian faience”, a sintered-quartz, non-clay ceramic. Analysis has revealed that the material from the site of Kerma, the centre of a Bronze Age Nubian civilization, is both of Egyptian manufacture and local production. Further investigation of both the composition and context of the faience has revealed a distinct and dramatic difference in the use and production of the material that references the political dynamic that developed between the two cultures, and which appears to be echoed in the succeeding Nubian Napatan and Meroitic Periods in Nubia. Keywords: Faience production, Kerma, cultural development,Napatan Period, Meroitic Period
C-Group cattle management in the Second Cataract area
Authors: Monroe Shayla
Published: April 2024

Here, I present a brief osteometric comparison of cattle from two archaeological assemblages in ancient Sudan. These measurements are reviewed in the context of regional variation in the size and shape of cattle in Kerma, Lower Nubia, and pharaonic Egypt. The evolutionary and ecological principles of variation and breed formation are described. Archaeological studies comparing cattle stature across ancient Europe and ancient Rome are considered, and then factors likely to have contributed to stature variations in Nile Valley cattle populations are discussed, including differential land use between the territories of Egypt, Lower Nubia, and Kerma, variations in local ecology, and divergent political trajectories and their associated implications for pastoralist production. Keywords: Cattle, Sudan, Nubian C-Group, Kerma, ecology, zooarchaeology
Foodways and cultural entanglements in New Kingdom Nubia
Authors: Smith Stuart Tyson
Published: April 2024

Foodways play an important role in both ancient and modern societies, particularly in the context of imperial expansions like the New Kingdom Egyptian occupation of Nubia after the conquest of Kush. On the one hand, access to certain foods and knowledge of and the means to properly deploy dining etiquette provide ways to emphasise the differential status of members of the colonial regime and its local collaborators. But in both elite and non-elite contexts, foodways also provide insights into the logics of adoption, adaptation, and rejection that characterise Dietler’s consumptionbased model of cultural entanglement. Entanglement complicates the binary dichotomy of Egyptian dominance and Nubian or Kushite subordination, instead allowing us to document mutual influence by tracing the different cultural threads that entangled to produce a new fabric that was itself dynamic, evolving over time as individual tastes shifted over the course of the colonial encounter. This paper focuses on domestic foodways, while also considering funerary and religious evidence. An ongoing re-analysis of data on intercultural interaction between colonists and local populations from Askut in Lower Nubia and recent excavation at Tombos in Upper Nubia informs a discussion of the intercultural social role and politics of taste within the colony. Keywords: Practice theory, colonialism, meals, feasting, taste, Askut, Tombos, Nubia
Material meanings, technology and cultural choices: Pottery production in Late Bronze Age Nubia
Authors: D’Ercole Giulia
Published: April 2024

This chapter tackles the concepts of materiality and style in relation to the manufacturing sequence of the production of Egyptian-style and Nubian-style vessels in Nile clay, presenting case studies from the two colonial sites of Sai Island and Dukki Gel (Kerma) in Late Bronze Age Nubia. Through a combined macroscopic and microscopic analysis of the ceramic assemblages, it was possible to determine in which stages of the chaîne opératoire the influence of the Egyptian and Nubian cultures, and associated pottery traditions, were the most emphasised. This demonstrates the potential of integrating a multi-analytical approach to the study of material evidence with the aim of expanding our knowledge of the interplay between the system of production and use of vessels, as well as the surrounding cultural and environmental landscape. Keywords: Materiality, chaîne opératoire, Late Bronze Age, Sudan, Nubian-style pottery, Egyptian-style pottery
‘Where are you from?’ The affective and emotional dimensions of an ambiguous event of everyday racism
Authors: Piwoni Eunike
Published: April 2024

This article discusses the various affective and emotional dimensions of how racialised individuals understand and cope with the ambiguous question of ‘Where are you (really) from?’ Theoretically, the article argues that people do not necessarily ‘comprehend’ racism but sense it, and that it is through affects and being affected that they understand the nature of an encounter. Empirically, the article is based on 21 in-depth interviews conducted with Black Germans, and it analyses respondents’ reflections on and ‘emotion memories’ of being asked the question of ‘Where are you from?’ Only a few respondents said that they had consciously decided to always regard the question as ‘normal’ and thus to ‘switch off their sensitivity’. Overall, when asked this question, interviewees relied on ‘affective thinking-feeling’ to determine whether there was racism to be sensed. By analysing respondents’ narratives of particular episodes in which they were asked the question, the article proposes that a specific assemblage and affective intensities are the main conditions for immediately sensing racism in and through the question. In addition, the article discusses interviewees’ range of response options and why and when respondents may engage in ‘emotion work’ when responding to the question. The article concludes by highlighting different types of emotions associated with sensing racism through the question, particularly the emotions of unease, discomfort, and disappointment that can lead to feelings of non-belonging.

Embodied, Salvaged, Reused: The Inadvertent Trajectories of Patching, Unpatching, and Repatching Carbon in Low-Income Housing Construction Practices in Karachi
Authors: Abdullah Adam , Macktoom Soha
Published: April 2024

Abstract: This article conceptualizes everyday processes of carbon embodiment and transplantation in informal settlements across Karachi, Pakistan. The authors explore these grounded carbon trajectories against the state’s carbon discourses and policies, highlighting the lacunae in the national (de)carbonization discourse particularly in the housing construction sector. In contrast, they look at grounded, unintended, and ad hoc practices of carbon embodiment and transplantation through the lens of the informal housing construction sector in urban Pakistan, drawing on several representative cases from extended fieldwork in Karachi during 2018–22. They examine how carbon is embodied and “transplanted” across spatial regions, intergenerational life courses, and the localized imaginaries of urban housing, through the everyday practices of residents (de/re)constructing and living in informal, patchworked houses. Against the backdrop of Karachi’s housing precarity, Abudallah and Macktoom observe peculiar temporal-material patterns that frame everyday carbon management for a large proportion of urban dwellers. They conceptually weave these cases together to speculate on patchwork housing processes, material redistributive practices, and carbon (dis)embodiment for populations lying beyond the state’s formal attempts at de-carbonization. They posit that understanding, accounting for, and upscaling the existing practices of patching, unpatching, and repatching carbon constitutes a critical lens to understand the smaller-scale yet more proximate and intense relations of carbon in under-documented cities like Karachi.
Dirty Industry, Heritage, and the Erasure of Immigrant Pasts
Authors: Lozanovska Mirjana
Published: April 2024

Abstract: Industry is dirty, and land, soils, and sites remain toxic even after operations have diminished or closed. Dominant heritage frameworks, aligned with narratives that serve national interests, and environmental plans, have not yet imagined the heritage futures of industrial landscapes— nor the narratives that link the industrial pasts of workers to the present and the future. Significant labor histories are frequently diminished, marginalized, or omitted altogether. Major nation-building industries in Australia, America, Canada and northern Europe were dependent on immigrant labor drawn from Asia, Europe, and South America, and their stories are embedded in the large tracts of industrial sites that have become wastelands of defunct and demolished structures. “Dirty” extends onto a linguistic terrain of “dirty histories” and the silencing of particular histories parallel the masking of environmental toxicity. Focusing on the Port Kembla steelworks in Australia, this article examines immigrant industrial labor history and develops a perspective from which to rethink heritage practice and the theoretical development of critical carbon. If critical carbon is conceptualized as a matter that concerns both the exploitation of land and of peoples, this article argues that heritage practice needs to develop projects around immigrant heritage sites such as the steelworks.
The "New Animism": Implications for a Postmodern Christian Spirituality
Authors: Frohlich Mary
Published: April 2024

Abstract: The movement called "new animism" asserts that experiencing life as an immersion in personal relationships with all beings (including those commonly regarded as "inanimate") is the foundational human way of being. The suppression of that immersive, participative way of life is currently climaxing as both cascading ecological catastrophe and an epidemic of human despair. This essay argues that Christian faith can fruitfully be reconciled with the new animism through a recognition of Christ's ability to "person" anywhere. Openness to this participative ecological consciousness invites us to develop new skills of attentiveness to the "thousands-of-years-old conversation" through which Earth and its creatures exchange their primal wisdom.
Finding God in the Eye of a Needle
Authors: Crisp Beth R.
Published: April 2024

Abstract: Textile artifacts associated with Christian worship and spirituality have been documented extensively. However, the spirituality of sewists themselves has received relatively little attention. In addition to the products created for sacred and secular use, there have long been sewists for whom sewing has been an inherently spiritual activity. This essay explores the ways in which sewing can be an embodied expression of Christian spirituality. It can be a means of service to the larger community as well as a means of spiritual expression for sewists themselves.
Ignatian Spirituality and Racism
Authors: Haight Roger
Published: April 2024

Abstract: This article uses the spirituality of Ignatius Loyola's Spiritual Exercises to show theologically Christianity's intrinsic bearing on American racism. Working from a definition of racism, and inspired by the work of Ignacio Ellacuría, it stipulates certain modern theological principles for interpreting the Exercises in a racist context, and then proposes four dimensions of the logic of the Exercises that bring them to bear on Christian life in America today.
Preliminary analysis on the characteristics of light absorption coefficients in typical rivers of different river basins across China
Authors: Zhang Yuting , Shen Qian , Yao Yue , Li Junsheng , Zhang Bing
Published: April 2024

As a vital constituent of water’s optical properties, the absorption coefficients influence the distribution of underwater light field, consequently impacting the structures and functional patterns of riverine ecosystems. In this study, the light absorption of non-algal particulates (ad(λ), m−1), phytoplankton (aph(λ), m−1) and CDOM (ag(λ), m−1) of 380 water samples collected from 133 rivers in eight external river basins across China from 2013 to 2023 were examined to determine the optical absorption characteristics. Results showed significant differences in ad(λ), aph(λ) and ag(λ) across different basins. ① The water bodies of eight basins can be categorized into 5 dominant types of absorption coefficients. ② In eastern China, ag(440) exhibited a northeast-high and southwest-low spatial distribution pattern. The Songliao River Basin had the highest ag(440) than other basins. The higher slope S of ag(λ) in rivers compared to lakes and reservoirs confirm river water primarily derive CDOM from external sources, distinguishing them from lakes and reservoirs. ③ The Huaihe and Haihe River Basins had higher ad(440) and aph(440) values, primarily due to lower terrain and human activities, leading to the accumulation of suspended particles and nutrients. And soil erosion from the Loess Plateau caused significant differences in ad(440) between the upper and middle reaches of the Yellow River Basin. These findings hold significant implications for understanding the optical characteristics of rivers in China.

Published: April 2024

In this study, we employed the principle of Relative Mode Transfer Method (RMTM) to establish a model for a single pendulum subjected to sudden changes in its length. An experimental platform for image processing was constructed to accurately track the position of a moving ball, enabling experimental verification of the pendulum’s motion under specific operating conditions. The experimental data demonstrated excellent agreement with simulated numerical results, validating the effectiveness of the proposed methodology. Furthermore, we performed simulations of a double obstacle pendulum system, investigating the effects of different parameters, including obstacle pin positions, quantities, and initial release angles, on the pendulum’s motion through numerical simulations. This research provides novel insights into addressing the challenges associated with abrupt and continuous changes in pendulum length.
Porcine reproductive and respiratory syndrome virus 2 hijacks CMA-mediated lipolysis through upregulation of small GTPase RAB18

Published: April 2024

RAB GTPases (RABs) control intracellular membrane trafficking with high precision. In the present study, we carried out a short hairpin RNA (shRNA) screen focused on a library of 62 RABs during infection with porcine reproductive and respiratory syndrome virus 2 (PRRSV-2), a member of the family Arteriviridae. We found that 13 RABs negatively affect the yield of PRRSV-2 progeny virus, whereas 29 RABs have a positive impact on the yield of PRRSV-2 progeny virus. Further analysis revealed that PRRSV-2 infection transcriptionally regulated RAB18 through RIG-I/MAVS-mediated canonical NF-κB activation. Disrupting RAB18 expression led to the accumulation of lipid droplets (LDs), impaired LDs catabolism, and flawed viral replication and assembly. We also discovered that PRRSV-2 co-opts chaperone-mediated autophagy (CMA) for lipolysis via RAB18, as indicated by the enhanced associations between RAB18 and perlipin 2 (PLIN2), CMA-specific lysosomal associated membrane protein 2A (LAMP2A), and heat shock protein family A (Hsp70) member 8 (HSPA8/HSC70) during PRRSV-2 infection. Knockdown of HSPA8 and LAMP2A impacted on the yield of PRRSV-2 progeny virus, implying that the virus utilizes RAB18 to promote CMA-mediated lipolysis. Importantly, we determined that the C-terminal domain (CTD) of HSPA8 could bind to the switch II domain of RAB18, and the CTD of PLIN2 was capable of associating with HSPA8, suggesting that HSPA8 facilitates the interaction between RAB18 and PLIN2 in the CMA process. In summary, our findings elucidate how PRRSV-2 hijacks CMA-mediated lipid metabolism through innate immune activation to enhance the yield of progeny virus, offering novel insights for the development of anti-PRRSV-2 treatments.

Libertad de tránsito y autoridad internacional en los primeros años de la Sociedad de Naciones
Authors: Sánchez Román José Antonio
Published: April 2024

La Sociedad de Naciones recurrió al término tránsito como una suerte de metáfora espacial vinculada al movimiento y la libre circulación, buscando reforzar su autoridad internacional. Este artículo explora cómo la SdN utilizó la idea de tránsito en la primera mitad de la década de 1920 para intentar construirse un espacio de autoridad, más allá de la soberanía territorial, presentando a la organización como la valedora de la libertad de movimientos de personas y mercancías, una de las claves para la cooperación y la paz internacional, según lo entendían los impulsores del nuevo orden internacional que se intentaba construir a partir de 1919. El artículo explora igualmente los límites que rápidamente emergieron para que los expertos de la Liga construyeran su autoridad sobre los principios del tránsito y la libertad de movimientos.

Hidden variables and Bell’s theorem: Local or not?
Authors: Allori Valia
Published: April 2024

Bell’s inequality is an empirical constraint on theories with hidden variables, which Einstein, Podolsky and Rosen argued are needed to explain observed perfect correlations if keeping locality. One way to deal with the empirical violation of Bell’s inequality is by openly embracing nonlocality, in a theory like the pilot-wave theory. Nonetheless, recent proposals have revived the possibility that one can avoid nonlocality by resorting to superdeterministic theories. These are local hidden variables theories which violate statistical independence which is one assumption of Bell’s inequality. In this paper I compare and contrast these two hidden variable strategies: the pilot-wave theory and superdeterminism. I show that even if the former is nonlocal and the other is not, both are contextual. Nonetheless, in contrast with the pilot-wave theory, superdeterminist contextuality makes it impossible to test the theory (which therefore becomes unfalsifiable and unconfirmable) and renders the theory uninformative (measurement results tell us nothing about the system). It is questionable therefore whether a theory with these features is worth its costs.
Az intellektuális bűnözés feltalálása
Authors: Perényi Roland
Published: April 2024

This paper examines the process during which Hungarian society „invented” the category of intellectual property crimes at the turn of the 19th and 20th century. Since the rapidly urbanizing capital was at this time the economic and financial center of the country, the focus of this investigation is Budapest. The effort to define intellectual property crimes can be identified in criminal law, criminology, and in public opinion as well. At the turn of the 19th and 20th centuries, the development of modern capitalist economy and bourgeois society happened extremely quickly in Hungary, so the modern forms of crime closely related to the process – including intellectual property crimes – were codified in the criminal law in response to this, in the framework of a longer process. From the sources available from the turn of the century, it is clear that crimes of an intellectual nature had already appeared in Hungary in the early period of the Austro-Hungarian Monarchy, but they only became really „visible” from the early 1900s. Then, as a result of the First World War and the social and economic crisis following the defeat, the number of white-collar criminals increased by leaps and bounds. Accordingly, from the 1920s onwards, the issue of intellectual property crime became a defining topic in both police and press discourse. While the amount of economic or financial crimes committed by white-collar people increased significantly in the early 1920s and then during the Great Depression, their quantity and the types of crimes also changed continuously, adapting to changes in the economic environment.
Behavior of Sand Specimens Subjected to Cyclic Loads under Drained and Undrained Conditions in Variable Loading Amplitudes
Authors: Thuy Do Van
Published: April 2024

Dynamic loads with different magnitudes cause shear stress and strain in the soil and increase the pore water pressure, reducing soil strength and leading to structural failure. This article presents the behavior of natural river-sand specimens subjected to cyclic loads under both drained and undrained conditions, as observed in cyclic triaxial tests conducted in the laboratory. The experiments were performed on sand specimens with a relative compaction of 0.95 when changing the loading amplitude with three different levels of 30 kPa, 50 kPa and 60 kPa. Experimental results show that, under the condition of drained cycle load, the pore water pressure does not form; only accumulated strain and dynamic parameters are almost unchanged. Meanwhile, with the condition of undrained cyclic load, the pore water pressure increases and causes liquefaction of the specimen, then the axial strain increases dramatically and is not capable of recovery. When varying the loading amplitude under drained condition, the initial-strength values increase as the amplitude of the load increases. This trend has the opposite direction when testing under undrained condition, which means that when increasing the loading amplitude, the initial-strength values decrease and the liquefaction potential of the specimens is faster. Further, under the undrained condition, the loading amplitude of 30 kPa effect is almost negligible on the liquefaction ability of the specimen. Keywords: Sand, Drained condition, Undrained condition, Loading amplitude, Cyclic triaxial tests
ARGUMENTATION OF A FORMULA FOR NUMERICAL ASSESSMENT OF EARTHQUAKE-RESISTANCE SHORTAGE OF BUILDINGS USING NONLINEAR STATIC PUSHOVER ANALYSIS IN SAP2000
Authors: Sosnin A.V.
Published: April 2024

The article is a continuation of research previously published in the Bulletin (2021, vol. 21, no. 2). Au-thor offers explanations and clarifications of a formula proposed to assess insufficient earthquake resistance shortage (hereinafter Id) of buildings using calculation procedures of nonlinear static Pushover analysis in SAP2000. An idea was implemented to graphically justify the mathematical expression used to determine Id with building age adjustments per building age. It was assumed that under certain conditions a change in service life-span (hereinafter referred to as Tst) of a building will lead to changes in the calculated acceleration of vibrations in proportion to the cube root of Tst. It was also assumed that at the end of a building's service life an earthquakes, can cause severe structural damage (or destruction) of its members, can occur. Change of a building age by estimation time of Id value was assumed to be distributed accord-ing to an exponential law. A value corresponding to the end of the building's service life Tst was taken an objectivity compliance criteria for the proposed formula for estimating of Id. Obtained an Id value should be confirmed by technical survey of buildings in seismic areas. Relationship curves of Id (Tst) were plotted according to a refined formula for the considered territory tremor values and earthquake waiting time. The obtained results can be applied to fulfill the re-quirements of term 6.19.11 of Seismic Design Building Code SP 14.13330.2018 and to be used as a supplement the cal-culation provisions laid out in the Assessment Procedure for Survey of Standard Buildings to Determine their Earth-quake Resistance and Need for Seismic Retrofitting (Kamchatgrazhdanproekt, 2009).
THE MATERIAL COMPOSITION AND PROPERTIES OF ASH FROM THE INCINERATION OF DOMESTIC SEWAGE SLUDGE
Authors: Shakhov S.A.
Published: April 2024

Ash generated by sewage treatment facilities – domestic sewage sludge (DWS) – is an untapped source of potential raw materials for the construction industry. We studied the material composition and properties of ash from the incineration of domestic wastewater. Ash consists of particles with a rough surface texture and porous microstructure and exhibits high absorbent properties. It has been established that the characteristics of ash produced by the incineration of DWS (the coefficient of philosity, true density, granulometric composition, the content of a number of oxides) differ significantly from ash produced by thermal power plants and loam which are used in the production of building materials. The proximity of the oxide composition of ash and loam makes it a rational choice as a fusible aluminosilicate raw material with an extended sintering interval. Hydraulic activity in the ash allows it to be considered as an active mineral additive for cement clinker. The crushing resistance of ash is comparable to that of expanded clay, which in some cases means it can be suitable as a filler or fine aggregate. The drainage characteristics of ash allow its use in the construction of road foundations.

Published: April 2024

The article assesses the impact of concrete biodegradation on the durability of concrete and reinforced concrete bridge structures. Areas of biocorrosion and other types of concrete corrosion were identified on real bridges. Based on the developed physical and mathematical model, we calculated the service life of reinforced concrete bridge supports and proposed economically advantageous terms for removing biodeposits from concrete. We also calculated the economic efficiency of removing biofouling from concrete and determined that the annual economic effect amounted to 9 % of the cost of the estimated work. If preventative measures against biofouling are carried out at least once every five years, the period for carrying out works to eliminate defects in concrete and reinforced concrete building structures can be in-creased by 1.5x. We provide recommendations to improve the durability and effective operation of bridge structures.
ROMAN CONCRETE: THE MATERIAL OF CONSTRUCTION HERITAGE
Authors: Sagdiyev R.R. , Belov S.V.
Published: April 2024

Statement of the problem. Many cultural heritage buildings of 17th–18th centuries in Russia and abroad require reconstruction not by modern systems such as ventilated facade or “wet facade”, but by authentic materials based on roman concrete. The authenticity lies in its unique structure, which is obtained after the drying of the plaster composition based on roman concrete. This material has a number of advantages: it permits the movement of steam and moisture, allowing the façade to breathe and preventing the growth of fungi and mold; it is lighter than plaster mixes based on Portland cement; and the texture is aesthetically pleasing. Compositions based on roman concrete have demonstrated their applicability in facade reconstruction, since it perfectly retains the old plaster, increasing service life. The purpose of this article is to give an overview of the production and use of roman concrete in the 17th and 18th centuries for finishing facades and stucco. Our task is to review and analyze the advantages and disadvantages of roman concrete and the experience of its production and use, and justify the prospects of researching and improving its composition and properties. Results. We define the necessary performance properties of roman concrete for the reconstruction and resto-ration of facades. Conclusions. Roman concrete is one of the few materials with a composition and structure compatible with architectural monuments that is suitable for restoration.

Authors: Gajda Katarzyna
Published: April 2024

In the last decade, there has been a marked increase in interest in the use of mobile technologies in education, especially in language teaching. In the context of Mobile Assisted Language Learning (MALL), mobile applications offer unique features such as personalization, interactivity, and access to online resources, promoting individual language learning processes and supporting traditional teaching methods. This article focuses on the analysis of the effectiveness of the Duolingo application in teaching Russian at the University of Warsaw. The study was conducted in the summer semester of 2021/2022 with a group of 78 students. The results confirmed the positive impact of Duolingo on student engagement and the efficiency of material assimilation, while emphasizing the need for technical and educational support for the full use of the application. Study participants were keen on using Duolingo, particularly appreciating the reading lessons, although exercises aimed at developing speaking and writing skills were perceived as less effective. The conclusions of the study indicate the need for further research on the application of Duolingo in foreign language teaching and the analysis of its materials in the context of glottodidactics.

ChatGPT can be used as an alternative resource when learning a foreign language. It has a wide range of applications, such as: working with vocabulary and grammar, practicing, testing and proofreading texts, practicing speaking, creating learning materials, automatically translating texts and providing information about countries, cultures, history and other aspects related to the foreign language being taught. Phraseological competence is an important element of general communicative skills, which enables the learner of a foreign language to use the language correctly, freely, and broadens knowledge of intercultural issues. The article analyses the possibilities of using a chatbot when learning foreign language phraseology. The study aims to assess the effectiveness of ChatGPT in the process of foreign-language phraseology acquisition. Texts from Russian and Polish textbooks containing phraseological units are used as material. The results reveal that for this purpose ChatGPT can be used partially because its effectiveness is related to the type of specific task. The Chatbot gives worse results when it is tasked with translating phraseological compounds or citing an example of their use, while it is promising as an alternative resource for creating educational content.
Poczucie własnej skuteczności studentów w rozwijaniu sprawności pisania w języku obcym

Self-efficacy is a well-known and researched concept originating from the social-cognitive theory of Albert Bandura (1977, 1997). However, it still seems to be able to promote interesting reflections that are important for language education in higher education, both in teacher and learner activities. According to a number of studies learners acquire important skills and attitudes that are linked to a high degree of self-efficacy: they are highly motivated to learn, set ambitious goals for themselves, and are more persistent and committed to learning than those with a low degree of self-efficacy. The text analyses the results of a quantitative-qualitative study conducted among students participating in foreign language classes at the University of Warsaw. The collected data is analysed with the aim of answering the following research questions: What is the level of self-efficacy in written expression in a foreign language at B2-C2 levels? How do the students perceive the teacher-lecturer’s actions to strengthen their sense of self-efficacy? Do they see strengthening their involvement in written expression as a key element of self-efficacy? In addition, we are also interested in their opinion towards the possibilities of Chat GPT in this regard. The results are used to propose some teaching activities that will enhance students’ self-efficacy in written expression at B2-C2 levels as an important motivational factor which may result in a sense of agency.
Emotions in Language Learning: Understanding Foreign Language Enjoyment and Anxiety in Higher Education
Authors: Łodej Monika , Osmoła Agnieszka
Published: April 2024

The significant role of emotions in learning was reemphasized during school and university closures caused by the COVID-19 pandemic. However, upon returning to campus, cognitive learning outcomes have reclaimed a dominating position in the university curriculum, while affective learning appears to have been disregarded. The present study contributes to the discussion on the significance of social-emotional learning in higher education. Therefore, the primary objective of this inquiry is to trace the perceived levels of foreign language enjoyment (FLE) and foreign language classroom anxiety (FLCA) in order to understand factors which contribute to their emergence. The research sample comprises 108 Polish university students majoring in English and enrolled in a bachelor’s programme. The findings demonstrate that language enjoyment is more prevalent among participants than language anxiety. The causes of language enjoyment are associated with teacher-student and peer-peer interactions as well as the classroom atmosphere, while language anxiety is reported to be linked to the fear of negative evaluation of students’ academic performance, test anxiety, and communication apprehension. These results suggest that English Department students are not exempt from experiencing language classroom anxiety, and engaging in practical English classes may be a source of a range of positive and negative emotions.
A Chrysippean Modality
Authors: Bailey D. T. J.
Published: April 2024

In this paper, I attempt to explain one of the most controversial views attributed to the Stoic Chrysippus: that the impossible can follow from the possible. My solution finds in Chrysippus a distinction later made by the medieval logician John Buridan: that between being
possible (there being a state of affairs that may occur) and being
possibly-true (there being some proposition whose truth-conditions are that state of affairs). Buridan and Chrysippus have radically opposing views on the nature of propositions. What their conceptions share is the conclusion that at least some propositions must be contingent beings. They argue for this while maintaining a rigorous commitment to the view that propositions are strictly bivalent. In 2. I explain the Chrysippean passage in terms of a distinction Buridan makes explicitly. In 3. I show how the distinction follows implicitly from the Stoic theory of quantification. In 4. I compare the modality with other aspects of Stoic logic. In 5. I discuss how the distinction behaves in the future tense.
Naufragés aux portes du Japon d’Edo (1603–1867) : Des frontières « infranchissables » et un espoir de retour
Authors: Kashkin Danila
Published: April 2024

It is often surmised that the Tokugawa shogunate (1603–1867) was obsessed with the notion of rigorous border control. During the first half a century of its existence, it had expelled from the country all Westerners but the Dutch, prohibited the Japanese from ever setting foot on foreign soil and banned the return of those abroad. Though, were the borders as impenetrable as they seemed to be? Historians agree nowadays that the bakufu maintained relations with the outside world and, even if international trade was restricted to certain nations and ports, it prospered still. The archipelago as well was far from lifeless. It was undergoing an intense urbanisation, centred mainly on the cities of Edo and Ōsaka. Before long, hosts of transport craft became a crucial part of the booming Japanese economy. However, shipwrecks were extremely common, and several hundred castaways ended up in Europe, in the United States or in their colonies in Asia, a fate that they viewed as worse than death, since they were theoretically forbidden from coming back. Many shipwrecked sailors chose to remain abroad, but some did return to their home country. This paper examines how they tried to cross a border that was reputed to be impossible to cross.
Identification of KDM4C as a gene conferring drug resistance in multiple myeloma

Bortezomib (BTZ), a proteasome inhibitor, is a promising therapeutic option for multiple myeloma (MM) patients. However, drug resistance often occurs, leading to disease relapse and poor prognosis. In this study, we aimed to identify novel genes associated with drug resistance and investigate their roles in BTZ resistance. Through the screening of 26 genes frequently associated with chemosensitivity or drug resistance, we discovered that KDM4C, a histone demethylase, exhibited increased expression in BTZ-resistant MM cells compared to their sensitive counterparts. Overexpression of KDM4C enhanced the tolerance of a MM cell line to the drug, whereas the knockdown of KDM4C, using shRNA, increased the sensitivity of resistant cells to BTZ treatment. This suggests that KDM4C plays a pivotal role in conferring BTZ resistance. Our study offers fresh insights into BTZ resistance in MM and highlights KDM4C as a potential target for overcoming drug resistance.
Analysis of muscle implanted antenna performance with the variation of implantation depth
Authors: Ghosh Soham , Gupta Bhaskar
Published: April 2024

Implantation depth of Implantable Medical Devices (IMDs) is an important factor of communication quality between implantable antennas in IMDs and external devices. Therefore, it is required to study the effect of implantation depth on implantable antenna performance. In this article, dependence of resonant frequency and scattering parameters of a two-antenna system where one miniaturized meander-line antenna is placed within human muscle tissue layer operating at 2.45 GHz ISM (industrial, scientific and medical) band and a rectangular patch antenna placed outside human body, are tested. Here 15 values of implantation depth ranging over 5–35 mm inside muscle layer are taken and for each case resonant frequency and scattering parameters (S
11 and S
21) of the system are recorded. Statistical analysis has been performed to observe how these performance parameters are dependent on depth of implantation which may be varied at the time of surgery.
