Efficient Numerical Solution of the Sharma-Tasso-Olver Equation Using Radial Basis Function-Pseudo Spectral Method with Comparative Analysis
Authors: Zebari Luqman , A. Pirdawood Mardan , I. Sadeeq Mohammed
Published: July 2024

In this study, we will solve the Sharma-Tasso-Olver equation by utilizing the radial basis function-pseudo spectral approach. Pseudo spectral techniques are renowned for their exceptional precision but have constraints regarding their ability to handle geometric variations. The integration of Radial Basis Functions (RBF) with pseudo spectral methods offers a solution to surmount this particular limitation. To estimate the differentials with respect to the variable , we will use the radial basis functions, including commonly used ones like multiquadric, inverse multiquadric, and inverse quadric, have been employed. Furthermore, the problem has transformed into the ordinary differential equation (ODE), and the solution to this ODE system has been acquired through the application of the fourth-order Runge-Kutta method. Additionally, a comparative analysis has been conducted between the solutions obtained through the suggested technique and the exact solutions.

Published: July 2024

Age differences in cognitive performance have been shown to be overestimated if age-related hearing loss is not taken into account. Here, we investigated the role of age-related hearing loss on age differences in functional brain organization by assessing its impact on previously reported age differences in neural differentiation. To this end, we analyzed the data of 36 younger adults, 21 older adults with clinically normal hearing, and 21 older adults with mild-to-moderate hearing loss who had taken part in a functional localizer task comprising visual (i.e., faces, scenes) and auditory stimuli (i.e., voices, music) while undergoing functional magnetic resonance imaging. Evidence for reduced neural distinctiveness in the auditory cortex was observed only in older adults with hearing loss relative to younger adults, whereas evidence for reduced neural distinctiveness in the visual cortex was observed both in older adults with normal hearing and in older adults with hearing loss relative to younger adults. These results indicate that age-related dedifferentiation in the auditory cortex is exacerbated by age-related hearing loss.
Tell China’s Conspiracy Well: Networks and Narratives of Anti-CCP YouTube Conspiracists
Authors: QIN Abby Youran , Xiao Fan , Linjie DAI
Published: July 2024

Regarding political conspiracy theories as a combination of factually problematic information and populist morality, we draw on Habermas’s theory of communicative action to analytically distinguish the factual and moral components of conspiracy theories. We combine social network analysis and discourse analysis to illustrate the networks and narratives of anti-CCP conspiracy theorists on YouTube. Inhabiting a peculiar information ecology and targeting an opaque government, these YouTubers constitute a critical case for understanding the networked dissemination of conspiracy theories and the discursive blend of truth and normative rightness claims in such theories. We first mapped out and compared the anti-CCP conspiratorial networks formed through YouTubers’ mutual endorsement and emerged naturally from users’ viewing behaviors. Three major segments of anti-CCP conspiracists were identified, namely a strategically coordinated Falun Gong group, a tightly knitted “Whistleblower Movement” block, and a loosely connected residual of political dissidents. Then, we conducted a discourse analysis on seven central channels in the network, illustrating how anti-CCP conspiracists legitimize their extraordinary claims by (1) leaping from basic facts to morally embellished informative fictions and (2) making reassuring doomsday predictions that dissipate revolutionary potential.

Published: July 2024

Background. Symptom reduction occurring early in depression treatment is associated with favourable post-treatment outcome, but it is not known how early reduction in specific depression symptoms affect treatment outcome. We aimed to determine the impact of symptom-specific change from pre-treatment to week four during internet-delivered CBT (ICBT) on overall and symptom-specific depression severityat post-treatment. We hypothesized that change in mood and emotional involvement would be moststrongly associated with later overall depression severity.Methods. 1300 participants with Major Depressive Disorder were followed over 12 weeks of ICBT using the self-report Montgomery-Åsberg Depression Rating Scale gauging nine symptoms. Linear models,informed by causal inference and cross-lagged network analysis methods, were used to estimateassociations between early symptom-specific change and post-treatment depression severity, controlling for register-based and self-reported pre-treatment confounders.Results. Early reduction in all symptoms was associated with lower overall and symptom-specific depression severity post-ICBT. Seven symptoms showed similar associations between early change andoverall depression severity post-treatment: mood (standardized beta [β]=0.44), feelings of unease(β=0.39), ability to concentrate (β=0.46), initiative (β=0.43), emotional involvement (β=0.42), pessimism(β=0.44), and zest for life (β=0.42). Change in sleep (β=0.27) and appetite (β=0.27) had weaker associations with overall depression severity at post-treatment and were the only symptoms showing the hypothesized difference compared with mood and emotional involvement.Conclusions. The impact of early symptom-specific reduction on post-treatment depression severity in ICBT for MDD may be similar across most symptoms, but less for the sleep and appetite symptoms, although causal interpretations rests on several assumptions.

THIS PAPER HAS NOW BEEN ACCEPTED AND PUBLISHED BY TRAVEL BEHAVIOUR AND SOCIETY. PLEASE REFER TO THE JOURNAL VERSION OF THE PREPRINT FOR THE MOST UPDATED VERSION.https://doi.org/10.1016/j.tbs.2024.100919Bike-riding GPS data offers detailed insights and individual-level mobility information which are critical for understanding bike-riding travel behaviour, enhancing transportation safety and equity, and developing models to estimate bike route choice and volumes at high spatio-temporal resolution. Yet, large-scale bicycling-specific GPS data collection studies are infrequent, with many existing studies lacking robust spatial and/or temporal coverage, or have been influenced by sampling biases leading to these data lacking representativeness. Additionally, accurately detecting bike-riding trips from continuously collected raw GPS data without human intervention remains a challenge. This study presents a novel GPS data collection approach by leveraging the combination of a smartphone application with a Bluetooth beacon attached to a participant’s bike. Aided by minimal heuristic pre-processing, our method limits data collection to trips taken by bike without the need for participant intervention, carefully optimising between survey participation, privacy challenges, participant workload, and robust bike-riding trip detection. Our method is applied to collect 19,782 bike trips from 673 adults spanning eight months and three seasons in Greater Melbourne, Australia. The collected dataset is shown to represent the underlying adult bike-riding population in terms of demographics (sex, occupation and employment type), temporal and spatial patterns. The average trip length (median = 4.8 km), duration (median = 20.9 min), and frequency of bicycling trips (median = 2.7 trips/week) were greater among men, middle-aged and older adults. The `Interested but Concerned' riders (classified using Geller typology) rode more frequently, while the `Strong and Fearless' and `Enthused and Confident' groups rode greater distances and for longer. Participants rode on roads/streets without bike infrastructure for more than half of their trips by distance, while spending 24% and 17% on off-road paths and bike lanes respectively. This population-representative dataset will be key in the context of urban planning and policymaking.

Published: July 2024

Children start formal schooling with substantial individual differences in their early literacy and numeracy abilities, but little is known about predictors of precocious (i.e. early advanced) reading and math. In this study, we investigated contributions from a range of cognitive and home-related predictors to early reading, arithmetic and applied math in 224 Dutch kindergartners (Mage=5;5). Our results showed that precocious reading and math were differentially predicted by specific combinations of domain-specific, domain-general and cross-domain cognitive skills. For reading, we primarily observed contributions from literacy-specific skills, especially letter knowledge. For mathematics, we observed contributions from various domain-specific, domain-general and cross-domain cognitive skills. Predictors of ‘basic’ arithmetic skills differed from predictors of ‘precocious’ arithmetic fluency, suggesting qualitative differences between typical and precocious learners. Contributions from children’s home environments (parental education levels, parent-child activities) provided small, yet notable results. Together, our results provide novel insights into the (co-)development of precocious reading and math in preschool-aged children.
Quality in Question: Assessing the accuracy of four heart rate wearables and the implications for psychophysiological research.
Authors: Sinichi Mohammadamin , Gevonden Martin , Krabbendam Lydia
Published: July 2024

Heart rate (HR) and heart rate variability (HRV) are two key measures with significant relevance in psychophysiological studies, and their measurement has become more convenient due to advances in wearable technology. However, photoplethysmography (PPG)-based wearables pose critical validity concerns. In this study, we validated four PPG wearables: three consumer-grade devices (Kyto2935, Schone Rhythm 24, and HeartMath Inner Balance Bluetooth) and one research-grade device (Empatica EmbracePlus, successor to the widely-used but discontinued Empatica E4). All devices were worn simultaneously by 40 healthy participants who underwent conditions commonly used in laboratory research (seated rest, arithmetic task, recovery, slow-paced breathing, a neuropsychological task, posture manipulation by standing up) and encountered in ambulatory-like settings (slow walking and stationary biking), compared against a criterion electrocardiography device, the Vrije Universiteit Ambulatory Monitoring System (VU-AMS). We determined the signal quality, the linear strength through regression analysis, the bias through Bland-Altman analysis, and the measurement error through mean arctangent absolute percentage error for each condition against the criterion device. We found that the research-grade device did not outperform the consumer-grade devices in laboratory conditions. It also showed low agreement with the ECG in ambulatory-like conditions. In general, devices captured HR more accurately compared to HRV. Finally, conditions that deviated from baseline settings and involved slight to high movement, negatively impacted the agreement between PPG devices and the criterion. We conclude that PPG devices, even those advertised and designed for research purposes, may pose validity concerns for HRV measurement in conditions other than those similar to resting states.
Challenges for a Computational Explanation of Flexible Linguistic Inference
Authors: Woensdregt Marieke , Blokpoel Mark , van Rooij Iris , Martin Andrea E.
Published: July 2024

We identify theoretical challenges for developing a computational explanation of flexible linguistic inference. Specifically, the human ability to interpret a novel expression (like "mask-shaming"), where inferring plausible meanings requires integrating relevant background knowledge (e.g., COVID-19 pandemic). We lay out (i) the core properties of the phenomenon that together make up our construal of the explanandum, (ii) explanatory desiderata to help make sure a theory explains the explanandum, and (iii) cognitive constraints to ensure a theory can plausibly be realised by human cognition and the brain. By doing so, we reveal the ‘force field’ that theories of this explanandum have to navigate, and we give examples of tensions that arise between different elements of this force field. This is an important step in theory-development because it allows researchers who aim to solve one part of the puzzle of flexible linguistic inference to keep in clear view the other parts.

Authors: Rana Shreema , Aadisukma Dana
Published: July 2024

Urban areas are dynamic and intricate, encompassing various social, economic, ecological, and cultural aspects. It's crucial to employ effective approaches and management methods to achieve sustainable urban development. Stakeholder analysis is pivotal in understanding their roles and responsibilities in this process. By analyzing potential stakeholders and their responsibilities, enhances achieving development goals. This paper uses ‘solid waste bank’ and ‘socio-cultural water management approach’ case of Surabaya, Indonesia and Lalitpur, Nepal respectively. The challenges stakeholders face when implementing have been studied and mapped. Additionally, the significance of stakeholders in implementing development plans and policies has been reviewed through relevant journals and reports, considering the current cases of solid waste management and water management only. The mapping of stakeholders’ problems and prospects revealed that none of the stakeholders had low influence and low importance in both Nepal and Indonesia. This finding suggests that further studies could explore other relevant aspects of the stakeholder dynamics that could contribute to developing eco-city in both the countries. Also mapping, synthesizing both situation and stakeholder of other practices, and upgrading the practices as well may help achieve eco-city, which is unique, inclusive and has the contextual flavors.

Authors: Sahani Kameshwar , Khadka Shyam Sundar , Sahani Suresh Kumar
Published: July 2024

Carbonation-induced corrosion is a major concern for reinforced cement concrete (RCC) structures, impacting their long-term durability and structural integrity. This review synthesizes the findings on the deterioration mechanisms in concrete structures, focusing on carbonation, chloride-induced corrosion, and time-dependent deterioration. The analysis includes discussions on predictive likelihood methods for estimating bridge reliability, the impact of environmental factors on carbonation, and standardized testing methods for assessing concrete durability. The review highlights the importance of understanding material characteristics and environmental conditions in designing durable concrete structures, emphasizing the processes of carbonation, its impact on rebar corrosion, and strategies for mitigation. Sheltered concrete carbonation resistance in metropolitan tropical climates is 10-20% lower than open exposure. SCM concretes exhibit equivalent or greater long-term carbonation resistance to OPC concretes, as evidenced by the increase in carbonation depth ( Δ xd) at ages greater than 5 years. The paper concludes with recommendations for integrating advanced modeling techniques and empirical studies to develop robust maintenance strategies and improve concrete mix designs for enhanced durability.

Authors: Galvez-Nieto Alexander
Published: July 2024

El boom del cómic en la actualidad del siglo XXI ha sido en gran parte por la reaparición de historia de superhéroes y su salto a la realidad cinematográfica. Esto ha suscitado un rápido y basto detalle de los diferentes escenarios donde se tiene la acción de los personajes. Pero muchas veces estos fondos se vuelven en personajes principales de la historia, cuentan una historia, un modo de habitar, la cosmovisión de los personajes, su pasado, presente e incluso futuro. Escenarios que son representaciones únicas de conceptos de vida, estilos arquitectónicos, diseños urbanos y edificaciones icónicas que se basan en una especulación de realidad alterna que en algunos casos pueden responder algunas interrogantes existenciales, mostrar un futuro originado por malas decisiones o simplemente permite soñar en realidades que gustarían habitar. Estos productos imaginarios pueden convertirse en referentes de estudio bajo el enfoque de análisis de una ciudad o arquitectura real, e invitar a la reflexión y crítica del tipo de espacio habitable deseado. Ante ello la presente investigación tiene como objetivo recopilar información teórica del estado del arte sobre la arquitectura imaginaria como producto del cómic. Para lograrlo, se compiló datos provenientes de tesis de maestría y doctorales, libros, ponencias y artículos de revistas científicas. La investigación comienza con la definición del cómic y la presentación de sus conexiones con la ficción y la arquitectura, luego sobre la relación arquitectura y ficción, la relación arquitectura y cómic; y finalmente presenta las arquitecturas imaginarias y las conclusiones del trabajo. Cabe señalar, que hay escasos trabajos actuales sobre análisis y reflexión de estas arquitecturas imaginarias producidas por el cómic, con un enfoque crítico arquitectónico. La mayoría de los estudios enfatiza la evolución de este medio artístico a lo largo de su existencia, los estilos de presentación y calidad gráfica, e incluso más recientemente, el estudio del cómic como herramienta didáctica tanto para estudiantes de educación básica como para estudiantes de arquitectura. La relación de la ficción, arquitectura y cómic es tan profunda y estrecha que permite considerarla como producto experimental o especulativo para tratar de resolver situaciones imaginarias o desafiar los conceptos actuales y seguir especulando sobre otras realidades o futuros alternos. Por eso se concluye que esta arquitecturas imaginarias o especulativas merecen ser estudiadas, porque son ejemplos de cómo se relaciona las necesidades de los habitantes con el espacio, idea prima de todo encargo proyectual de arquitectura real.

This text explains why the results of research carried out in the State of Acre in the years 2002 to 2008 were released late, with financial support from two research projects financed by the CNPQ (SelenMerAs and Geosedintama) and a third (Ageopam) which also had a slight facet towards the region of this State. Although several works were published through communications at events and journals, much was restricted to dozens of dissertations, TCCs and reports from IC/PIBIC and others. It was concluded that even after almost 20 years, it was still opportune to disseminate these results and discussions, mainly because they are focused on the geological, mineralogical, multi-element chemical and fertility characterization of sediments on river cliffs, beach sands (bars in Pontal) and suspended sediments from rivers and lakes, in addition to environmental impacts, mainly on the wave of mercurial problem announced loudly in those years, which covered the entire Amazon. The BOMGEAM bulletin was chosen to disseminate unpublished results, due to its low cost, speed and accessibility. There will be two issues dedicated to the topic: BOMGEAM – ACRE 1 and BOMGEAM – ACRE 2. Issue 1 is dedicated more to the geology, mineralogy and geochemistry of sediments in ravines and bars; and number 2 to sediment fertility and potential environmental impacts. There are 13 contributions, involving dissertations, TCCs and monographs from IC/PIBIC and PDR.

The State of Acre is situated in the southwestern portion of the Amazon region and occupies 3.16% of its area. Two systems of drainage cross it: Juruá and Purus rivers. During the dry season, some beaches (point bars) are formed in the concave parts of the meanders. An example of this is observed on the Acre River, tributary of the Purus River. Incidentally, this area is of great historical importance for the region, as it was the site of a battle between Brazil and Bolivia for ownership of the State of Acre. Those beaches, which occur on the edges of the main rivers of the Acre, are intensely used for agriculture of subsistence of short cycle (beans (Vigna unguiculata (l) Walp), maize (Zea- Mays) and watermelon (Citrullus Lanatus) by the local peasants. These cultures occupy small areas, up to 2 hectares, on these beaches. Such situation is different from those on beaches from other regions of the Amazonia and Brazil. With the purpose of understanding the source of these sediments and the origin of this fertility, the present work was developed.The main unity of the State Acre is Solimões Formation, that occupies more than 80% of its surface (SEHA, 2000). It is formed mainly by argilites with carbonized organic matter (Radambrasil, 1976), and some fossils fragments of vertebrates and invertebrates. Locally, argillaceous siltites, calcareous rocks, ferruginous arenites and polimithics conglomerates are found (Radambrasil, 1976). On this Formation it was deposited holocenic sediments which constitute in part unstable abrupt declivities and, currently, beaches in both the edges of the rivers.The beach sediments, mainly in the cultivated areas, are predominantly siltics with unimodal distribution. The grains are angular to sub-angular and are constituted mainly of quartz, followed by smectite, illite, kaolinite and feldspar. The chemical composition shows high values of SiO2 (84,0 ± 4,7%, n = 10), and moderate to low values of the oxides (1 to 6%): Al2O3 (6,1 ± 1,7%, n = 10), Fe2O3 (2,7 ± 0,6%, n = 10), K2O (1,3 ± 0,2%, n = 10); Na2O (0,43 ± 0,12%, n = 10), CaO (0,28 ± 0,08%, n = 10) and MgO (0,4 ± 0,15%, n = 10), compatible with the mineralogical assembly identified, and therefore very different from those of other fluvial beaches, which are very poor in these components. Mineral constituents, such as feldspar and smectite and the angular form of the grains beach sediments, indicate immature evolution being Solimões Formation the source of these sediments.The fertility show that these sediments are comparable the eutrofic cambissols, with high capacity of exchange of cations (~ 11.01 Cmolc/Kg) and percentage of saturation of bases (v) above 90, indicating that they are in fact appropriate for agriculture. This fertility is related to clay minerals (smectite and illite) and its siltic and loosely bound grains.
CARACTERIZAÇÃO MINERALÓGICA DOS SEDIMENTOS DO IGARAPÉ DIABINHO (FORMAÇÃO SOLIMÕES) NO ESTADO DO ACRE – PROVENIÊNICA E IMPLICAÇÕS AMBIENTAIS

Igarapé Diabinho, situated in the central region of the state of Acre, is a tributary on the right bank of the Envira river, belonging to the Juruá river basin. Its U-shaped grooved channel is carved in sediments known as the Solimões Formation, of Late Miocene–Pleistocene age. The rocky exposures along Diabinho stream demonstrate a succession of massive silt-clay sediments, covered by other compact sandy silts cemented by carbonates. These sediments are partly overlain by alluvial (fluvial-lacustrine) sediments from the Quaternary, in the region where this stream dominates. For the study, samples collected in three profiles along a ravine on the right bank of Igarapé Diabinho were investigated, in an area used for picnics during the dry season, that is, with slight human disturbance. To assist in identifying the probable source areas of these sediments, and determine their weathering and transport conditions, granulometric analyzes were carried out, investigating the mineralogical composition of the sediments, their heavy minerals, and the mineralogy of the sediments’ clay fraction. The sediments are predominantly silts with little clay, being composed of quartz, feldspars (albite and microcline), clay minerals (smectite, illite, and kaolinite), muscovite, and chlorite. As a result, the sediments were deposited in mild paleoclimatic conditions under weak chemical weathering, indicated by the predominance of unstable minerals, such as amphiboles, feldspars, biotite, epidote, garnet, apatite, and titanite. The dominant presence of aluminosilicates (kyanite, andalusite, sillimanite, garnet, and micas) and epidote indicates that these sediments had as their primary source metamorphosed pelitic rocks. A second assemblage composed of tourmaline, zircon, apatite, titanite, and even ilmenite points to possible contributions from basic and intermediate igneous rocks that are currently observed in Serra do Divisor on the borders of Brazil and Peru. In conclusion, these findings contribute to implications in the paleoenvironmental context by providing insights into the probable source areas of the sediments, determining the weathering and transport conditions, and identifying the mineralogy of the sediments.

The state of Acre, located in the southwest of the Brazilian Amazon, is drained by two large river basins, the Purus and Juruá rivers, which have their sources on the sub-Andean slopes of Peru and cross the state in a path almost parallel to each other and a southwest-northeast direction. They are meandering rivers, with a large amount of suspended sediment (suspended solids or load materials), which gives them their white or muddy color, in addition to transporting a lot of silty-sandy sediments by traction, forming significant beach bodies (pointed bars). The geological terrains drained by these rivers are made up of rocks from the Solimões Formation and sediments from the Alluvial Terraces. The present work sought to characterize the granulometry, mineralogy and chemical composition of suspensions from rivers in the State of Acre. These were subjected to granulometric analysis, mineral identification using X-ray diffraction (XRD) and scanning electron microscopy (SEM/SED) and total chemical analysis of trace elements. The highest concentration of suspended solids was found in the central part of the State both during the flood and dry periods, while the lowest are in the Moa and Paraná dos Mouras rivers. They are predominantly made up of silt with little fine sand and clay, averaging 12 microns. Mineralogically, they are made up of quartz, mica, smectite, illite, kaolinite, as well as albite and K-feldspar. These are sediments rich in SiO2 (55.69% +/- 3.89%), Al2O3 (18.68% +/- 1.76%), Fe2O3 (5.89% +/- 0.41%), with significant K2O values ​​(1, 93% +/- 0.07%), MgO (1.17% +/- 0.22%), Na2O (0.41% +/- 0.06%), in addition to TiO2 (0.85% +/- 0.10%). The values ​​of P2O5 (0.10% +/- 0.014%), CaO (0.14% +/- 0.17%) and MnO (0.10% +/- 0.021%) are at crustal levels. In terms of trace elements Rb, Sr, Cs, Ba, Th, U, Zr, Hf, Y, Nb, Cr, Co, Ni, Cu, Sc and V, are the elements that presented the highest concentrations. The average concentrations of these elements in the suspended materials when compared with beach sediments show enrichment in Al2O3, Fe2O3, MnO, MgO, Rb, Cs, Sc, and V. On the other hand, with the upper earth’s crust they show enrichment in Cs, Y, Cr, Co, Ni, Cu, Sc and V and with post-Archaean Australian shales only slightly enriched in Y. The presence of clay minerals (smectite, illite and kaolinite) and feldspars (albite and K-feldspars) are responsible for the high concentrations not only Al2O3 and Fe2O3, but also K2O, MgO and Na2O. The mineralogical and chemical composition shown by these suspensions, in addition to their granulometry, contribute to fertilizing both the floodplains (“varzeas”) as well as the beaches exposed by the rivers during the dry period, which are intensely cultivated with corn (Zea-mays) and beans (Vigna unguiculata (L) Walp) by riverside dwellers.

Published: July 2024

INTRODUCTION: Chronic venous insufficiency (CVI) is a common condition especially among those of advance age that is often neglected. As the disease severity progresses, it increases the healthcare cost and resources required, while diminishing the quality of life of the persons. Health-related Quality of Life (HRQoL) among CVI patients begins to decline once the symptom starts to appear, and reduces it further as the symptoms worsens. MATERIALS AND METHODS: This is a prospective, multi-centred, cross-sectional study on consenting symptomatic CVI patients who presented to the International Islamic University of Malaysia (IIUM) teaching hospital in Pahang, Malaysia. The diagnosis of CVI was confirmed on duplex imaging. Clinical grading was performed using Clinical Etiologic Anatomic Pathophysiologic (CEAP) classification. Patients completed generic validated Malay language Short Form 36 (SF36) HRQoL instrument. RESULTS: One hundred and ten patients (62% male) with a mean age of 57 years, Malays (60%), Chinese (25%) and Indian (15%) were recruited. The most frequent CVD symptoms reported were pain (42%). The clinical, aetiological, anatomical, and pathophysiological (CEAP) classification placed most patients in the C2 class (34%). Apart from partaking in social functions, all other elements of mental and physical health component of SF 36 showed a marked deterioration as the disease progressed.

The philosophy of art is an important aspect of the study of art and culture, playing a key role in understand-ing the fundamental concepts and ideas behind various art forms. In this article, we examinedthe basic con-cepts of the philosophy of art and their influence on modern culture, as well as exploredthe humanizing sig-nificance of art. The goal of this study is to develop a systematic understanding of the nature of art from a so-cial philosophy perspective, revealing its humanizing role in shaping personality, and analyzing the essential characteristics of “new art”in the context of Ortega y Gasset's teachings. While there are numerous theories of art, it cannot be claimed that its essence, specificity, and social significance are fully comprehended, with debatable issues remaining in its understanding. The complexity and multifaceted nature of art as a phenome-non of human life make it challenging to create a complete and final theory. It is difficult to say that this issue has been sufficiently addressed in our country, as it reflects our society and requires complex philosophical consideration.
The relevance of F. Barth's ideas for modern studies of ethnicity
Authors: Mukanova A.K. ,   Karaganda University named after E.A. Buketov
Published: July 2024

The concept of ethnicity continues to be an important factor for the analysis of modern society of the XXI century. This text is devoted to a critical analysis of the relevance of Frederick Barth's research conducted in 1969 and presented in the work “Ethnic Groups and Borders”. Barth's theoretical model reveals diversity and consistency at the junction of ethnic boundaries, the connection between which is due to the heuristic correlation of the author's concepts reflecting the static and dynamic identity in the aspect of ethnicity. Of particular interest are the less popular categories of Barth's discourse, which represent the positive and negative labeling of ethnic groups in acts of nomination and discrimination. An attempt to draw attention to F.'s ideas, which have already become classic and therefore somewhat outdated. Barth's work is due to the incredible plasticity of his methodology, which, combined with modern approaches (for example, symbolic interactionism) can become a very useful tool for studying ethnic issues in our time. Addressing the ethnic issues of Barth's works contributes to a deeper rethinking of the reality around us and an understanding of the principles of functioning of modern society.

Sufism is one of the significant and greatest philosophical phenomena that have played a huge role in the spiritual life of the Muslim world. In Central Asian countries, Sufism was a theoretical and practical model of Islamic culture. Therefore, in the present time when post-Soviet countries face the issue of national identity, the questions related to spiritual heritage, including Sufism, are particularly relevant. Detailed studies of the works of renowned theorists are necessary for a deep understanding of this religious phenomenon. Ibn Arabi is one of the significant figures representing a significant interest in the philosophical and practical study of Sufism. Almost all the works of the Great Sufi are dedicated to knowing God, knowing the world, and know-ing human beings. Based on the analysis of the thinker's works and the known studies of modern authors, the authorsof thearticle tried to demonstrate the types of knowledge presented in the works of Ibn Arabi. In the article the methods of comparative analysis, paradigmatic approach, and general philosophical studieswere used. At the same time, different positions on the understanding of Ibn Arabi's gnoseological ideas in the re-search environmentwere demonstrated. The authors aimed to show that Ibn Arabi's teachings on knowledge have a character that goes beyond mysticism and encompasses a philosophical concept. The essence of Su-fism and philosophy lies in the continuous pursuit of truth, rather than perceiving it as a predetermined entity that seizes a person's being. Instead, it entails the understanding and assimilation of truth, paving the way for the vast expansion of spiritual contemplation and ultimately allowing individuals to embody this truth. Ibn Arabi's philosophical teachings on knowledge revolve around acquiring truth, and consistently serving man-kind.

SHAPING THE NOVEL
Authors: Mitchell Constantina Thalia , Côté Paul Raymond
Published: July 2024

The dialogue between form and message is intrinsic to the novel as genre. Yet the strength of that discourse has been shaken in the twentieth century by an increasing doubt about affirmations of any kind and a growing awareness of the relativity of knowledge and perception. The novel reflects this intellectual current by turning its glance inward to mediate on the creative act as a form of self-contained assertion of its own particular significance. The three writers on whom this study focuses, all major twentieth century authors, were chosen because they can be considered as important representatives of this novelistic self-consciousness. Building on André Malraux's vision of the colloquium as an open-ended verbal interchange, this study calls upon the voices of Anne Hérbert and Patrick Modiano to enter into a dialogue on novelistic form.
OSTHANDEL AND OSTPOLITIK
Authors: Spaulding Robert Mark
Published: July 2024

Eclipsed by the scope of the Atlantic economy, obscured by Anglo-German rivalry, and nearly destroyed by the post-1945 division of Europe, the flow of goods across East Central Europe has been, nonetheless, an immensely significant pattern of European economic exchange. For Germany, the Osthandel (Eastern trade) was both a blessing and a curse; its bounty provided much of the raw material for the rise of German economic and political power in Europe, while its lure tantalized German ambitions to the point of madness. Despite the enduring importance of this commerce, no monograph has yet made this pattern of trade the centerpiece of its treatment of German-East European relations. This study puts this important pattern of German-East European trade into the center of discussion and views an extended period of German foreign policy toward Eastern Europe through this lens.
