Turning-Induced Residual Stresses in CoCr28Mo6 Dual Modular Hip Endoprostheses
Authors: Denkena B. , Legutko B. , Bergmann B. , Prasanthan V.
Published: February 2025

To enhance patient care, it is necessary to increase the lifetime of double modular hip endoprostheses with tapered junctions. One approach to increasing the lifetime of components is to adjust the residual stress state to the load. Therefore, this study investigates the influence of process parameters and the effect of their interaction on the residual stresses of neck adapters manufactured from CoCr28Mo6. With the investigated process parameters, compressive residual stresses are present after turning. This study reveals the interaction and issues between surface roughness and the high bending of the surface due to the small radius of the samples in the measurement of residual stress.
Analysis of Energy Requirements in Thermochemical Heat Treatment Using the Example of Gas Nitriding
Authors: Oelker T. , Waldenmaier T. , Fechte-Heinen R. , Hoja S. , Steinbacher M.
Published: February 2025

In recent years, the metal processing industry has undergone a massive rethinking in terms of energy use. With the phase-out of nuclear energy, Germany wants to take responsibility and embark on a more sustainable path to green electricity. Not only due to the discontinuation of fast-available nuclear energy, but also due to the increasing demand for electrical energy and the geopolitical situation, the costs for production are continuously rising. Furthermore, the use of fossil fuels has come under criticism in the face of current climate policy discussions, and the procurement of fossil fuels such as natural gas has experienced a significant price increase due to the current geopolitical situation. A more efficient use of energy and resources is therefore essential, also with regard to socio- and environmental factors and, in particular, climatic aspects.

In this work, a standard industrial gas nitriding process is examined with regard to its key energy figures and potential savings are identified. On the basis of these, the significance of the heating of the components, the insulation technology and other process-relevant energy flows is determined. It was found that, on the basis of conservative calculation models, the heating of these industrial furnaces types is among the largest energy consumers, whereas only a smaller part is required for treating the components. Furthermore, the majority of the electrical power provided dissipates as power loss from the heat treatment process.

α-UO3 is a common intermediate compound found in the nuclear fuel cycle, yet the exact crystal structure of this material has long been debated. Inconsistent computational and experimental data in previous works has led to varying conclusions between authors. To ensure the validity of our results in this work, the structural and spectroscopic signatures of pure phase α-UO3 are investigated using powder X-ray diffraction and optical vibrational spectroscopy (infrared and Raman). Rietveld refinement of powder X-ray diffraction data on pure phase α-UO3 collected in this work allows us to propose an alteration to the currently accepted C2mm structure (a = 3.9705 Å, b = 6.8553 Å, c = 4.15955 Å, α = β = γ = 90°) for α-UO3 with no uranyl [UO2
2+] bonds. Raman spectra collected using two excitation wavelengths (two instruments using 532 nm and one 785 nm) are presented, and differences with recently published results are discussed. Infrared spectra from two instruments used here agree well with recently published results, but the spectral range encompassed in our data extends past what has been reported with modern techniques. Additionally, we provide tentative vibrational mode assignments based on density functional perturbation theory calculations and resulting phonon eigenvector visualizations. Unexpected features in the optical vibrational spectra of α-UO3 are explained by unique features in the structure we present.
Ein verletzliches Leben. Vulnerable Existenzweisen, performative Praktiken und ihre politische Beziehung
Authors: Lluis Conrad
Published: February 2025

Der Aufsatz fragt nach der Stellung der Vulnerabilität in der Gesellschaft. Als Ausgangspunkt dienen zwei gegenläufige Verständnisse von Vulnerabilität: einerseits gerinnt Vulnerabilität zu einer scheinbar unveränderlichen sozialen Tatsache, andererseits wird sie ständig politisch herausgefordert. Um diesen Widerspruch aufzulösen, werden zwei konträre Vulnerabilitätsbegriffe sozialtheoretisch so reformuliert, dass sie als Pole eines dynamischen Kontinuums erscheinen. An einem Pol steht Judith Butlers ontologischer Begriff von Vulnerabilität als basale Abhängigkeit von einer Um- und Mitwelt, am anderen Pol das in öffentlichen Debatten dominierende Verständnis von ‚vulnerablen Gruppen‘, die fest und handlungsunfähig scheinen. Die Vulnerabilität bewegt sich stets, so die These, in der Spannung zwischen diesen zwei Polen. Mittels eines von Butler stammenden, aber anhand der Ethnographie der Plattform der Hypothekbetroffenen (PAH) Barcelona analytisch ausgebauten Konzepts der kollektiven Performativität wird zunächst der aktiv-transformative Pol der Vulnerabilität ausformuliert. Im Rückgriff auf die Gender Studies, insbesondere auf Andrea Maihofer, sowie auf Einsichten der konstruktivistischen Disability Studies und der Arbeitssoziologie nach Bahl und Staab wird anschließend der Begriff der vulnerablen Existenzweise eingeführt. Dieser Begriff steht für den passiv-erfahrenden Pol der Vulnerabilität. Der aktive und der passive Pol der Vulnerabilität werden durch eine politische Beziehung verwoben.

Authors: Basu Biswajit , Rahaman Monosiz , Ghosh Sourav , Dutta Swarnali , Kumar Ashwini , Mukherjee Swarupananda , Singh Sudarshan
Published: February 2025

Sericin, a protein extracted from the cocoons of silkworms, has recently become an attractive biomaterial due to its potential as a good candidate for wound healing especially wounds seen in diabetic and immune-compromised patients. This review discusses the special biological nature of sericin such as its water-solubility and inherent moisturizing properties, antimicrobial, and antioxidant activities, which can act synergistically to foster ideal conditions for wound healing. The incorporation of sericin into composite wound dressings along with other natural and synthetic polymers was found to improve the mechanical properties, biocompatibility, and overall therapeutic performance. Moreover, the review draws attention toward sericin-based materials in diabetic wound healing with a focus on promoting rapid tissue regeneration and cell proliferation and enhancing clinical outcomes that conventional therapeutics cannot serve. The review also discusses the challenges associated with the production and application of sericin-based wound dressings and outlines the prospects for this emerging field. As research continues to advance, silk sericin holds the potential to revolutionize wound care, offering innovative solutions for the effective and holistic management of complex wounds.
How Often Are Constraints on Generality (COGs) Discussed? A Look at Articles Published in Four Psychology Journals 2018-2022
Authors: Zhu Jasmine , Cai Huanchen , Shoda Yuichi
Published: February 2025

Constraints on Generality statements (COGs, Simons, et al., 2017) address the boundary conditions of study findings, informing readers of the participant populations and methodological and social/cultural/historical contexts within which the reported phenomena are expected to occur. This in turn informs readers of the contexts in which additional studies are needed, facilitating cumulative science. Knowledge of boundary conditions is also crucial for conducting meaningful direct replications of findings (Simons, et al., 2018). In our review of 282 articles, we found that 6 included a separate COG subsection. The proportion of articles that contained any explicit COG statements anywhere in the discussion section ranged from 5% to 40% across the four journals we examined. This proportion was higher in journals whose editors publicly encouraged inclusion of COGs. We believe continued monitoring of the inclusion of COGs would be beneficial not only in psychology but also for other scientific disciplines.

Dobiveni rezultati ukazuju na metodičke, organizacijske i spoznajne teškoće pri ostvarivanju odgojno-obrazovnih ishoda nastavne jedinice u kojoj je primijenjena metoda eksperimenta. Razlike u stavovima učitelja daju indikacije za unaprjeđenje učiteljskih i učeničkih znanja i sposobnosti te vremensku i prostornu prilagodbu eksperimenta u nastavi s ciljem razvitka kvalitetnijih prirodoznanstvenih kompetencija.
СИНТЕЗ АЗОТИРОВАННОГО КОМПОЗИЦИОННОГО МАТЕРИАЛА ИЗ ФЕРРОАЛЮМОСИЛИКОЦИРКОНИЯ В РЕЖИМЕ ГОРЕНИЯ
Authors: БОЛГАРУ К.А. , РЕГЕР А.А.
Published: February 2025

Рассмотрена возможность получения композиционного материала из ферросплава на основе нитридов кремния, алюминия и циркония методом самораспространяющегося высокотемпературного синтеза. Показано что внесение азотсодержащей добавки на основе ферроалюмосиликоцирконии в количестве до 35 масс. % к исходному ферросплаву приводит к увеличению содержания азота, выходу основных нитридных фаз в продуктах горения, замедлению продвижения фронта волны горения и уменьшению максимальной температуры горения. Выявлено, что внесение предварительно азотированного материала более 20 масс. % позволяет перевести режим распространения фронта волны горения в стационарный и получить продукты горения с макрооднородным составом. В условии естественной фильтрации азота горением порошковой смеси на основе ферроалюмосиликоцирконии и азотированного материала получен композит, состоящий из фаз AlN, Si3N4 и ZrN и α-Fe.

The possibility of obtaining a composite material from a ferroalloy based on silicon, aluminum, and zirconium nitrides by the method of self-propagating high-temperature synthesis is considered. It is shown that introduction of a nitrogen-containing additive on the basis of ferroalumosilicozirconium in amounts up to 35% to the initial ferroalloy leads to an increase in the nitrogen fraction, emission of the basic nitride phases in combustion products, deceleration of motion of the combustion wave front, and reduction of the maximum combustion temperature. It is found that introduction of a preliminary nitridized material in amounts of more than 20% makes it possible to convert combustion wave front propagation to a steady regime and to obtain combustion products with a macroscopically homogeneous composition. Under the conditions of natural filtration of nitrogen, combustion of a powder mixture based on ferroalumosilicozirconium and a nitridized material yields a composite consisting of AlN, Si3N4, ZrN, and α-Fe phases.

Представлено исследование процесса механохимического синтеза нитрида титана в условиях двойной механической активации (МА) порошка титана: в аргоне и в газообразном азоте. В экспериментах варьировали времена МА титана в аргоне и в азоте. Анализ морфологий порошковых смесей, данных рентгенофазового и микроанализа показал, что предварительная МА титана в аргоне способствует ускорению механохимического синтеза нитрида титана. Получены аналитические соотношения и даны теоретические оценки, позволяющие прогнозировать процесс двойной механоактивации титана.

A study of the process of mechanochemical synthesis of titanium nitride under conditions of double mechanical activation of titanium powder: in argon and in nitrogen gas is presented. In the experiments, the time of mechanical activation of titanium in argon and nitrogen was varied. Analysis of the morphology of powder mixtures, X-ray diffraction and microanalysis data showed that preliminary mechanical activation of titanium in argon helps to accelerate the mechanochemical synthesis of titanium nitride. Analytical relationships are obtained and theoretical estimates are given that make it possible to predict the process of double mechanical activation of titanium.

Authors: Phukan Himraj , Lynser Donboklang , Lyngwa Gareth Yobel , Daniala Chhunthang , Barman Himesh , Ghosh Tamajyoti
Published: February 2025

Pott’s Puffy Tumour (PPT) is an inflammation and swelling of the forehead secondary to osteomyelitis of the frontal bone. Multiple aetiologies are associated with this condition, predominately involving a prior sinus surgery or a direct trauma to the frontal bone. There can be intracranial extension with an epidural, subdural as well as intracerebral abscess. We present the case of an 8-year-old boy who presented with swelling in his forehead secondary to trauma. His general condition was poor, and further evaluation revealed multiple subdural empyemas. Although PPT is rare in this modern era of antibiotics, it should be kept as a differential for any inflammation of the forehead. Timely diagnosis and the appropriate treatment by a multidisciplinary team are indispensable in reducing the morbidity and mortality associated with this case.
The Life of Chariton the Confessor (September 28) by Symeon the Metaphrast asa Source for the Life of John the New of Suceava (June 2) by Gregory Tsamblak
Authors: Temčinas Sergejus
Published: February 2025

The article demonstrates that while writing the Life of the martyr John the New of Suceava, the first national Moldavian saint, the internationally known prolific Bulgarian author Gregory Tsam- blak must have used one of several existing Church Slavonic versions of the Byzantine Life of the venerable Chariton the Confessor, written by Simeon the Metaphrast, which is quite different it its plot. It is manifested in a quite extensive verbatim quotation of its incipit in the opening sentence of the text. Tsamblak must have consulted the Byzantine Life in its East Slavonic version, as the collation pre- sented in the article evidently shows, since only a weak connection with the South Slavonic version can be traced. The fact that Tsamblak used Symeon’s hagiography in the Church Slavonic translation and not in the Greek original excludes the theoretical possibility that the Life of John the New was origi- nally written in Greek by a different (anonymous) author, as it is sometimes assumed. It is explained by Gregory Tsamblak’s appreciation of the Jerusalem Typikon, quite new in the early 15th-century Moldova, while creating the new national Moldavian church cult of John the New of Suceava, since the ecclesiastic tradition features Chariton the Confessor as the earliest “creator” of the Jerusalem Typikon.
Francisk Skorina, Wroclaw and Adam Dyon: Book Migration and the First Paleotype of the Grand Duchy of Lithuania
Authors: Morozova Nadežda , Parshenkov Aleksandr
Published: February 2025

This article provides an analysis of the early history of a copy of Akathists by Francisk Skorina, held in the Wroclaw University Library, along with a detailed examination of the edition’s specific decorative features. Evidence is presented demonstrating that this copy of the Akathists formerly belonged to Daniel Prinz von Buchau.
Through a thorough study of the historical context, the authors conclude that Skorina employed se­ condary printed materials in the production of his Akathists.
The hypothesis regarding the possible Nuremberg origin of certain decorative elements in Skorina’s edition of Akathists is supported by the findings presented in this article. The information also substantiates the assumption that Skorina spent time in Wroclaw and engaged with local publishers. Furthermore, it is demonstrated that parts of The Little Traveller’s Book could not have been printed in Prague. This article is the first to publish scientifically verified information about the connection between Francisk Skorina and Adam Dyon, and it includes images of decorative elements shared by both printers. Additionally, it suggests the possibility that Skorina utilized materials from the Leipzig printer Martin Landsberg in his work. The arguments presented provide a robust basis for confirming the chronology of the first paleotype of the Grand Duchy of Lithuania.
Латинизмы в текстах литовских татар (на примере тефсира из Олиты 1723 г.)
Authors: Kozhinowa Alla
Published: February 2025

The article is devoted to the analysis of Latinisms in the tefsir from Olita, the Polish translation of the Koran, which, being made by the Tatars of the Grand Duchy of Lithuania, is the oldest translation of the holy book of Islam into the Slavic languages. Both direct borrowings and indirect ones, when there was another intermediary language between the donor language (Latin) and the recipient language (Polish), are considered. It was noted that the text contains the largest number of nouns of Latin origin, followed by verbs, and adjectives are few in number. The article concludes that the presence of Latinisms in the text of the translation indicates that the translators belonged to the culture of the Polish gentry, and number of Latinisms per unit of text (25 word usages out of 6000 word usages of the text, what, according to researchers, was characteristic of Polish literature in the 16th century) confirms the dating of the lost prototype of the tefsir to the end of the 16th century. The fact that the formal signs of some Latinisms indicate their penetration into the text of the translation through the East Slavic languages confirms the fact of its creation in the territory directly bordering on the territory of distribution of these languages.
ТРЕНДИ ЗМІН У ЗОВНІШНІЙ ПОЛІТИЦІ КИТАЮ В КОНТЕКСТІ ФОРМУВАННЯ НОВОГО СВІТОВОГО ПОРЯДКУ: ЕКОНОМІЧНІ ТА ПОЗАЕКОНОМІЧНІ ВИМІРИ
Authors: СІДЕНКО Володимир
Published: February 2025

Проаналізовано новітні тренди в міжнародній економічній і позаекономічній політиці Китаю, які виразно виявили себе за останні роки, особливо в умовах нинішньої глобальної безпекової кризи. Головну увагу приділено еволюції політико-економічних пріоритетів країни в міжнародній сфері, змінам у політиці стосовно глобальних і регіональних економічних організацій та їх впливу на систему світового порядку і стан міжнародної безпеки.
Показано, що ухвалені Китаєм за останні роки стратегічні ініціативи активізують поширення альтернативних поглядів на світовий порядок на основі реалізації принципу багатополярності, утвердження альтернативної моделі процесу глобалізації, міжнародного розвитку на підставі стратегічної концепції «Спільне майбутнє для людства». Ця політика має системний характер і стратегічно орієнтована на істотну зміну чинних механізмів глобального регулювання. Цей міжнародний курс Китаю розглядається Заходом як стратегічний виклик і започаткував період стратегічної конкуренції за майбутній формат світоустрою, а також спричинив тенденції фрагментації світової економіки.
Підкреслено необхідність широкого глобального співробітництва, а не глобального протистояння і ведення військових дій у процесі переходу до оновленого світового порядку. Значний вплив на цей процес матимуть майбутній формат розв’язання глобальної безпекової кризи і завершення російсько-української війни. Обгрунтовано, що Китай може сказати своє вагоме слово в цьому процесі на основі торжества сили права, від чого істотно залежатимуть майбутній рівень довіри до глобальних ініціатив Китаю і можливості їх імплементації.

A szervezeti adaptabilitás és az otthoni munkavégzés lehetőségének hatása az észlelt stressz, magányosság és általános jóllét kapcsán
Authors: Klajkó Dóra , Csapó Gyöngyvér Virág , Czibor Andrea
Published: February 2025

Háttér és célkitűzések: A 21. századi szervezeteket a folyamatos és rendkívül gyors változás jellemzi. A világjárvány idején a szervezeti rugalmasság kérdésköre még nagyobb prioritást élvezett, amely a szervezet működésének kulcskritériumát is jelentette egyben. A rugalmasság nemcsak a munkavégzés módjára (online, távmunka, munkaidő-kedvezmények), hanem a szervezeti tanulásra és a változásokra való fogékonyságra is kiterjed. Mindezzel szorosan összefonódva a munkavállalói egészségvédelem és a mentális jóllét is előtérbe került. A korábbi szakirodalmi eredményeket alapul véve jelen kutatás célja volt, hogy feltárjuk a szervezeti rugalmasság különböző aspektusait a munkavállalói jóllét szempontjából. A változásra és tanulásra fókuszáló szervezeti kultúrát, valamint egy rugalmas szervezeti intézkedést, a távoli munkavégzés hatásait vizsgáltuk meg részletesebben. Módszer: Kutatásunk 203 fő magyar munkavállaló bevonásával zajlott, amely során a pandémia után tapasztalt megváltozott munkavégzési sajátosságokat és a munkavállalói jóllét aspektusait vizsgáltuk. Az adatgyűjtéshez a Denison Organizational Culture Profile (OCP) adaptabilitás skáláját, valamint a munkavállalói észlelt stressz kérdőívet (PSS), a WHO általános jóllét kérdőívét (WHO10) és az UCLA Loneliness Scale (Magányosság Skála) 8 itemes verzióját használtuk. Emellett rákérdeztünk arra, hogy a kitöltő az elmúlt két hónap során milyen gyakran végezte a munkáját otthonából. Eredmények: Az adatelemzés során Structural Equation Modeling (SEM) eljárást alkalmaztunk egy elméleti modell felállítása céljából, amely a szervezeti adaptabilitás és az otthoni munkavégzés hatásainak mechanizmusait tárja fel a munkavállalói jóllét látens változói kapcsán. Ezen belül egy multigroup elemzést is végeztünk a nemi különbségek feltárására. Következtetések: A SEM elemzés során erős modellilleszkedést találtunk, illetve kimutatható volt, hogy a szervezeti adaptabilitás pozitívan hat a munkavállalói jóllétre, míg az otthoni munkavégzésnek nincsenek szignifikáns hatásai. A multigroup elemzés során feltárult az otthoni munkavégzés nőkre és férfiakra nézve eltérő hatása. Míg a nők esetében nem találtunk szignifikáns hatást (nem szignifikáns fordított korrelációt igen), addig a férfiak esetében egy közepes erősségű pozitív kapcsolat rajzolódott ki a munkavállalói jóllét kapcsán, amely eredmény illeszkedik a korábbi nemzetközi kutatások eredményeihez is.
Economy and Ethnicity. The Recolta Agricultural Cooperative as a Driver of Local Economic and Social Resilience in the Village of Csanálos
Authors: Szilágyi Levente
Published: February 2025

This study examines the impact of the agricultural cooperative currently operating in Csanálos (Urziceni), a Swabian settlement in Szatmár (Satu Mare), on the local economy and society. Agricultural cooperatives played an important role at the beginning of the process of agrarian transformation after the regime change in Romania. Established on a voluntary basis, the successor organizations to the socialist agricultural collectives were able to offset the impoverishment brought about by re-peasantization or forced peasantization during the long transition period, provided a stable financial basis for communities in the difficult periods following the regime change, and, often taking over state responsibilities, represented social cooperation and trust-based social localism. On the other hand, they took advantage of their monopolistic position to hinder the emergence of individual and family farmers. The risk-averse, self-reliant economic model of the cooperatives evokes the self-sufficient organization of peasant farms. Cooperatives can thus be seen as a very specific form of post-socialist post-peasant production system.

The study addressed the challenges of poor performance in numeracy knowledge at primary educational level by exploring the innovative strategy of whole school instructional model to improve teacher teaching-learning strategies and pupils’ attitude/interest towards numeracy at primary level of education. Three objectives and research questions were raised with two hypotheses. The pre-test, post-test quasi-experimental design was adopted with a focus on public primary schools’ pupils and teachers teaching numeracy within Plateau state central educational zone. The target population for the study comprised 523 primary five pupils in public schools enrolled in 2023/2024 academic session with sample size of 32 pupils in two intact classes from two Local Government Areas within the plateau central educational zone. The instruments for data collection were self-constructed questionnaire and achievement test titled “Teachers Numeracy Teaching Methods/strategies Observation Checklist (TNTMOC)”, “Pupils Numeracy Achievement Test (PNAT)”, and “Pupils Interest/attitudes towards Numeracy knowledge Checklist (PINKC)”. The instruments were validated using face and content validity by experts and the reliability index of 0.76, 0.75 and 0.81 respectively determined by Cronbach Alpha and split-half Methods. Data was analyzed using mean, standard deviation and paired sampled t-test to examine the differences of the repeated measure on pupils in the study. The study found significant improvement in teachers’ teaching strategies and Pupils interest/attitude in numeracy teaching and learning processes respectively with significant Pupils’ numeracy performance after being exposed to whole school instructional model. The study therefore recommended the use of whole school instructional model in teaching and learning of numeracy at primary school level.
Analysis of Optimal Tax Ratio and Efficiency of Regional Tax Revenue: A Case Study of Provinces in Indonesia

This study explores the impact of regional tax ratios on economic growth across 34 Indonesian provinces from 2013 to 2022, using the Fixed Effects Model for panel data regression analysis. The primary results reveal a substantial positive relationship between the regional tax ratio and economic growth, with a coefficient of 71.22% (p < 0.01). This finding suggests that increasing the regional tax ratio can effectively promote economic growth when optimally managed. However, the study also uncovers a non-linear relationship where the squared regional tax ratio has a negative impact on economic growth, with a coefficient of -2067.14% (p < 0.01) beyond a certain threshold. This indicates that while moderate increases in the tax ratio can be beneficial, exceeding the optimal regional tax ratio may suppress investment and economic activity. Additionally, the research shows that the ratio of regional revenue from non-tax sources and the ratio of central government transfer revenues negatively affect economic growth, with coefficients of –39.63% (p < 0.01) and –11.65% (p < 0.01), respectively. Conversely, the ratio of other regional revenues demonstrates a significant positive impact on growth, with a coefficient of 9.20% (p < 0.01). The study identifies an optimal regional tax ratio (RTMG) of 1.72%, compared to an average tax ratio of 1.20% during the study period, highlighting the potential for increasing the tax ratio to approach or reach RTMG to maximize economic growth. Based on these findings, it is recommended that regional governments pursue sustainable management of the regional tax ratio, diversify revenue sources, optimize the allocation of central government transfer funds, and invest in infrastructure and human capital. Routine evaluation of fiscal policies is also advised to adjust tax strategies in response to evolving economic conditions, aiming to achieve long-term sustainable economic development.
The Dynamics of Tax Compliance: How Attitudes, Social Influence, and Peer Effects Shape SME’s Compliance Behavior in Tanzania
Authors:   University of Dodoma, Dodoma, Tanzania, Buzohera Mohamed Issa
Published: February 2025

Low tax compliance rates among small and medium-sized enterprises (SMEs) in developing countries, including Tanzania, pose a significant challenge to national revenue collection and economic stability. This study delves into this persistent issue by examining the interplay between attitudes toward tax compliance and the influence of social dynamics on compliance behavior. Using structured questionnaires administered to SMEs in Dar es Salaam and Dodoma, the analysis reveals a strong positive relationship between tax compliance attitudes and behavior (β = 0.527, t = 7.573, p < 0.001), indicating that favorable attitudes significantly boost the likelihood of compliance. Additionally, social influence, particularly peer effects, plays a pivotal role, positively impacting compliance (β = 0.286, t = 4.333, p < 0.001). These findings emphasize the critical role of social networks, peer support, and prevailing social norms in shaping tax behaviors. The study highlights practical implications, advocating for educational programs to enhance tax knowledge and foster positive tax attitudes among SMEs. Furthermore, engaging local communities and business associations is essential to cultivating supportive environments that encourage voluntary compliance. By offering fresh insights into the combined effects of attitudes and social forces, this research provides actionable recommendations for policymakers and tax authorities to craft strategies that address attitudinal barriers and leverage social dynamics for improved tax compliance among SMEs. The study’s theoretical contributions lie in extending the application of the Theory of Planned Behavior by incorporating social dynamics as critical elements influencing tax compliance. Practically, the findings emphasize the importance of leveraging social networks and community norms to foster voluntary compliance.
Advancements in Viral Genomics: Gated Recurrent Unit Modeling of SARS-CoV-2, SARS, MERS, and Ebola viruses
Authors: Devaraj Abhishak Raj , Marianthiran Victor Jose
Published: February 2025

ABSTRACT Background: Emerging infections have posed persistent threats to humanity throughout history. Rapid and unprecedented anthropogenic, behavioral, and social transformations witnessed in the past century have expedited the emergence of novel pathogens, intensifying their impact on the global human population. Methods: This study aimed to comprehensively analyze and compare the genomic sequences of four distinct viruses: SARS-CoV-2, SARS, MERS, and Ebola. Advanced genomic sequencing techniques and a Gated Recurrent Unit-based deep learning model were used to examine the intricate genetic makeup of these viruses. The proposed study sheds light on their evolutionary dynamics, transmission patterns, and pathogenicity and contributes to the development of effective diagnostic and therapeutic interventions. Results: This model exhibited exceptional performance as evidenced by accuracy values of 99.01%, 98.91%, 98.35%, and 98.04% for SARS-CoV-2, SARS, MERS, and Ebola respectively. Precision values ranged from 98.1% to 98.72%, recall values consistently surpassed 92%, and F1 scores ranged from 95.47% to 96.37%. Conclusions: These results underscore the robustness of this model and its potential utility in genomic analysis, paving the way for enhanced understanding, preparedness, and response to emerging viral threats. In the future, this research will focus on creating better diagnostic instruments for the early identification of viral illnesses, developing vaccinations, and tailoring treatments based on the genetic composition and evolutionary patterns of different viruses. This model can be modified to examine a more extensive variety of diseases and recently discovered viruses to predict future outbreaks and their effects on global health.
How to Redo Things with Words: Deniability and the Determinants of Illocutionary Force
Authors: CLAPP LEONARD
Published: February 2025

Abstract When one speaks duplicitously one performs a (risky) speech act and at the same time intends that one have deniability regarding that speech act. What is it for a speaker who performs an illocutionary act to have deniability regarding that act? I first review an answer to this question proposed by Alexander Dinges and Julia Zakkou. According to them, deniability is “an epistemic notion. A speaker has deniability if she can make it epistemically irrational for her audience to reason in certain ways” (2023, p. 373). I argue, however, that the epistemic account is refuted by a counterexample, and informed by the counterexample, I propose an alternative. According to my alternative account, deniability concerns illocutionary norms: a speaker has deniability regarding an illocutionary action iff (i) she is permitted to deny having performed the action, and (ii) if she denies having performed the action, she thereby avoids being responsible for it. I conclude by considering the implications of illocutionary norms account of deniability for the vexed issue of the determinants of illocutionary force; I argue that the illocutionary norms account of deniability provides evidence in support of McDonald’s (2021) “collaboration” view.
Emprego e salários na indústria “O caso brasileiro”
Authors: TAVARES MARIA DA CONCEIÇÃO , SOUZA PAULO RENATO
Published: February 2025

RESUMO As características excludentes do modelo de desenvolvimento capitalista na América Latina podem se manifestar em dois fatores principais: baixos níveis de salários, que forçam os trabalhadores a viver na pobreza, e a marginalização de uma parte da população que não consegue sequer igualar o nível de salário dos trabalhadores. Este artigo tem a intenção de analisar a evolução do setor industrial no Brasil à luz de tais fatos.

O conceito de mark up nos modelos de distribuição e crescimento
Authors: LIMA LUIZ ANTONIO DE OLIVEIRA
Published: February 2025

RESUMO Este artigo tem como objetivo discutir algumas questões relacionadas aos modelos de crescimento e distribuição pós-keynesianos e como a introdução do conceito de mark-up pode contribuir como uma alternativa ao modelo de distribuição e se tornar uma característica fundamental para construir um modelo de crescimento. Partimos da suposição de que a análise de Harrod não menciona nenhuma contribuição para explicar a distribuição. Kaldor visa eliminar tais limitações por meio da suposição não realista de que a economia está sempre operando sob pleno emprego. Mostramos como a introdução do mark-up pode ser uma solução para essa questão.

Published: February 2025

Adequate fruit and vegetable consumption is recognized for its health benefits, including preventing noncommunicable diseases, therefore it should be monitored over the years. This study aimed to investigate the temporal trend of fruit and vegetable consumption among Brazilian adults (≥ 18 years) residing in 26 Brazilian capitals and the Federal District from 2008-2023. A time-series analysis of the Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel) was conducted. Regular (≥ 5 days/week) and recommended (≥ 5 servings/day on ≥ 5 days/week) fruit and vegetable consumption were analyzed for total population and sociodemographic groups. Prais-Winsten regression models were used to identify trends in the entire (2008-2023), initial (2008-2014) and most recent (2015-2023) periods. Regular and recommended consumption remained stable from 2008 to 2023. From 2008 to 2014, regular consumption increased in total population (0.71pp/year) and all sociodemographic groups, except for adults aged 25-34 years. From 2015 to 2023, regular consumption decreased in the total population (-0.56pp/year), mainly among men (-0.70pp/year), adults aged 25-34 years (-0.84pp/year), and with higher schooling (-0.96pp/year). The recommended consumption increased from 2008 to 2014 (0.81pp/year), mainly among women (0.90pp/year), adults aged 55-64 years (0.96pp/year), and those with higher schooling (0.77pp/year). The recommended consumption decreased from 2015 to 2023 in total population (-0.52pp/year) and all sociodemographic groups, except for men and adults aged ≥ 65 years. The Brazilian fruit and vegetable consumption increased from 2008 to 2014 but reduced recently (2015-2023).
Vacunación infantil: dudas, ambigüedades y toma de decisiones en mujeres-madres de sectores medios de Argentina
Authors: Mantilla María Jimena , Alonso Juan Pedro
Published: February 2025

Resumen: En los últimos años, las actitudes de rechazo o reticencia a la vacunación y el crecimiento de los llamados “movimientos anti-vacunas” han sido definidos como un desafío para la Salud Pública. El objetivo del artículo es analizar los procesos de decisión de mujeres madres de sectores medios del área metropolitana de Buenos Aires, Argentina, respecto de la vacunación de sus hijos/as, dando cuenta de los factores que disparan actitudes de reticencias o temores a la vacunación. Se realizaron 35 entrevistas en profundidad con mujeres madres de sectores medios de la Ciudad de Buenos Aires, identificadas con estilos de maternidades “naturales” o afines a la denominada “crianza respetuosa”. Se describen diferentes trayectorias o recorridos hacia la reticencia o el rechazo a la vacunación: (a) generadas ya por comentarios o indicaciones de profesionales de la salud durante el parto o controles pediátricos; (b) derivadas de cambios más generales en los estilos de vida, marcados por la opción por cuidados de la salud alternativos o “naturales”; (c) inscriptas en procesos de crítica y desconfianza sobre la biomedicina y la afirmación de la autonomía sobre las decisiones en salud; y (d) a partir de una búsqueda activa de información en fuentes principalmente contrarias a la vacunación. Las dudas o ambigüedades en torno a la vacunación que presentan estas madres no se traducen unívocamente en el rechazo a la vacunación, sino en una diversidad de prácticas: de la vacunación con reparos, la selección o el retraso de algunas vacunas, y la no vacunación.
