Enhancing sound transmission loss of polyurethane foams using waste soda glass filler
Authors: Yeşilyurt Ayşenur
Published: December 2024

Sound transmission mechanisms and sound transmission losses are of great importance in providing acoustic comfort. Research has focused on developing materials and structures that will reduce sound transmission loss. The increasing amount of waste disrupts the ecological balance; this situation brings about global warming, air and soil pollution. These environmental effects negatively affect the lives of all living things, especially humans, and also harm the economy. Combating global pollution has become one of the primary goals of scientists. Recycling provides significant economic benefits as well as protecting both human health and natural resources. In this study, polyurethane foams used in the automotive industry and many other areas were produced by adding waste soda glass powder at various rates while keeping the isocyanate/polyol ratio constant. The durability of the produced foams was tested by apparent density measurement, wettability by contact angle analysis, organic bond structures by FT-IR spectroscopy and acoustic properties by sound transmission loss analysis. It was determined that soda glass powder did not react with the foams and that the produced foams exhibited hydrophobic properties. The acoustic properties of the filler foams were higher than the neat foam in almost the entire frequency range (65-6300 Hz). The sample coded PU-SG4 is the sample that exhibits the best acoustic properties by reaching 9.28 dB, 9.10 dB and 13.48 dB values in the low, medium and high frequency regions, respectively. In the high frequency range region, all of the soda glass added foam composites reached a sound transmission loss of over 13 dB.
ANGER. DEGRADED REBEL AND TRAGIFARSE REVOLUTION (INTERPRETATION OF DYGRESJE NA TEMAT KALOSZY BY MICHAŁ CHOROMAŃSKI)
Authors:   Jagiellonian University, Kraków, Poland, Natkaniec Daniel
Published: December 2024

The aim of this article is to attempt a detailed analysis and interpretation of the novel “Dygresje na temat kaloszy” (1966) by Michał Choromański. I have focused my attention primarily on the numerous descriptions of rage in this work, which determines the existence of a mentally unstable individual. In this text, one can also find frequent descriptions of intellectual rebellion directed against foreign axiological models. Importantly, however, Choromański presents the phenomenon of a broadly defined breakthrough (for example: moral, social, cultural, civilizational) in a distorting mirror, with a characteristic dose of irony and sarcasm. Plusk-Zawiły (the main character), although he lives in an unnamed Western country, undertakes a tireless fight in the name of restoring an old-fashioned, thoroughly Sarmatian system of values. The protagonist’s painful defeat results in an outburst of uncontrolled, untamed, psychosomatic impulses. For this reason, I use the recently popular affect theory, the implementation of which allows me to pay more attention to the issue of fluid, difficult to define physical and spiritual tensions, eagerly raised by the author. In “Dygresje na temat kaloszy”, the feeling of rage leads to the melting, crumbling, of the subject’s identity. The enraged subject, it would seem, usually demonstrates his own strength and advantage (both psychological and physical) over the other people. But this is not what happens in “Dygresje na temat kaloszy”. In Choromański’s novel, anger turns out to be a manifestation of weakness, internal instability, and the instability of the ego instance. The writer uses descriptions of rage on an à rebours basis: the more bluntly Plusk-Zawiły expresses his indignation, the more he resembles a clown deprived of power and agency. What is the prospect for an individual who is exceptionally susceptible to the influence of the above-mentioned affect? If we were to follow the writer’s advice given in “Dygresje na temat kaloszy”, we would have to say: there is little that can be done. At best, we can close our eyes and surrender to unbridled intensity.

Published: December 2024

Entrepreneurial Orientation (EO) has become an important research domain in the entrepreneurship literature to analyze the ability of firms to maximize the opportunities in the market. Similarly, considering the distinct context of firms in transition economies, networks have become an integrated part of analyzing firms in these contexts. Therefore, the purpose of this study is to examine the impact of EO dimensions (innovativeness, proactiveness, and risk-taking) and networks on micro-, small-, and medium enterprises' growth. This study employs a cross-sectional study on 438 firm owners/managers in four sectors in the case of Kosovo. Findings show highly statistically significant and positive results for all three dimensions: proactiveness, risk-taking, and innovativeness, and a positive and statistically significant relationship between networking and firm growth. All control variables remain consistent regarding statistical significance after introducing EO dimensions. Only when introducing the networking variable does the variable denoting university-level education become negative and statistically significant compared to the non-university education of managers.

INTERNATIONALISATION OF SMALL AND MEDIUM SIZED ENTERPRISES – INSIGHTS FROM THE LITERATURE
Authors:   Josip Juraj Strossmayer University of Osijek, Koprivnjak Popovic Tihana
Published: December 2024

Given their role and importance, small and medium-sized enterprises (SMEs) are the driving force in many economies. Researching their specificities is a basis for understanding their needs and possible levers that would enable their growth and development. The internationalisation of SMEs is a different process from the internationalisation of large companies and it is necessary to understand the specificities of this process. This paper reviews the literature in order to summarise the existing knowledge on the process of internationalisation of small and medium-sized enterprises. The aim of this paper is to provide a conceptual framework that offers a comprehensive overview of various important aspects of the internationalisation process. The proposed framework explains factors, barriers and possible approaches to SME internationalisation and provides guidance for future empirical research.

Svrha je svakog poslovanja ostvarivanje profita pa je glavni cilj ovog istraživanja utvrditi utjecaj internih čimbenika i indeksa BDP-a po stanovniku u odnosu na prosjek EU-a kao eksternog čimbenika na profitabilnost poduzeća. U radu je provedena regresijska analiza na uzorku od 181 velikog dioničkog društva u zapadnoj Europi iz različitih sektora. Interni čimbenici uključuju financijske pokazatelje te veličinu i starost poduzeća, dok se za procjenu utjecaja makroekonomskog okruženja na poslovanje poduzeća, koristio indeks BDP-a po stanovniku u odnosu na prosjek EU-a. Također je istražen utjecaj ESG pokazatelja na profitabilnost poduzeća s obzirom na to da se radi o internom čimbeniku koji mjeri održivost poslovanja poduzeća i utjecaj na okoliš, socijalnu odgovornost i upravljačke aspekte poslovanja. Sukladno s očekivanjima, rezultati analize ukazuju na to da profitabilnija poduzeća imaju viši ESG pokazatelj, nižu zaduženost i veći udio dugotrajne materijalne imovine u ukupnoj imovini. Ostale analizirane varijable nisu se pokazale značajnima. Rezultati imaju praktične implikacije za poduzeća, investitore, regulatorne tijela te donositelje političkih odluka. Istraživanje ističe potrebu za objavljivanjem izvještavanja o održivosti, uključujući objavu ESG rezultata, što bi značajno doprinijelo poboljšanju održivih poslovnih praksi.

Published: December 2024

This study investigates the performance of composite brake pads made of Ulin (Eusideroxylon zwageri) sawdust using simulation modeling, focusing on the pressure distribution, frictional stress, and contact state in five brake pad designs (DS0 to DS4). The brake pad designs used U-shaped grooves to improve cooling efficiency and debris removal. The results show that DS1 and DS2 exhibit the most uniform pressure distribution, with maximum values of 0.045 MPa and 0.048 MPa, respectively. DS1 recorded the highest peak frictional stress at 2.53 × 10-8 MPa, while DS2 showed consistent stress stability, reducing the possibility of uneven wear. DS3 achieved a balanced performance, with a maximum pressure of 0.062 MPa and a stable frictional stress distribution. In contrast, DS4 showed the highest stress (0.072 MPa) and increased “sliding” contact area, indicating reduced braking efficiency and potential for faster wear. Contact condition analysis showed predominantly “sticky” conditions on DS1, DS2, and DS3, which contributed to effective braking performance, while DS4 exhibited significant “sliding” conditions, which reduced friction efficiency. These findings confirm the potential of Ulin sawdust as an environmentally friendly brake lining material, with DS1 and DS2 emerging as the most suitable designs to achieve optimal braking performance and long life.

Authors: Menéndez-Cuervo Pablo , Vílchez-González José Miguel
Published: December 2024

Aunque hoy en día la importancia del conocimiento científico sea cada vez más evidente y la tecnología esté más presente que nunca, el interés de los estudiantes por la ciencia está en claro declive. Las metodologías tradicionales no les motivan, no logran captar su atención ni les demuestran su utilidad para resolver problemas que, cada vez más a menudo, requieren de un enfoque interdisciplinar. El presente estudio analiza la actitud hacia la ciencia de cuatro alumnos de 3º ESO de un Programa de Mejora del Aprendizaje y Rendimiento (PMAR), antes y después de participar en tres proyectos STEM. Si bien su carácter es piloto y la vocación científica del alumnado no se ve modificada, su interés por la ciencia sí aumenta. De hecho, confirman comenzar a valorarla y a disfrutar de ella. Por tanto, aunque no se cumplan todos los objetivos de la educación STEM, la participación en proyectos de este tipo propicia la mejora de la alfabetización científica y la actitud hacia la ciencia.

Published: December 2024

Desde la didáctica de las ciencias se ha puesto de manifiesto la necesidad de una visión global de los problemas y soluciones interrelacionados que caracterizan la situación de emergencia planetaria. Sin embargo, en la generalidad de trabajos publicados, se echan en falta instrumentos que contribuyan a la visión holística para evitar adquisiciones dispersas y lograr visualizar, de manera global, las relaciones existentes entre factores claves. Para hacer frente a esta disfunción, se ha propuesto la elaboración de mapas conceptuales a los participantes en cursos y talleres dirigidos al profesorado en formación y en activo, así como a colectivos ciudadanos. Los resultados obtenidos permiten concluir que la elaboración y discusión colectiva de dichos mapas contribuyen a establecer la vinculación de los problemas socioambientales y a comprender la necesidad de su tratamiento conjunto, para sintetizar, clarificar y reforzar los conocimientos adquiridos.
Key competencies and role profiles for sports managers: a multi-dimensional analysis
Authors: Carranza-Bautista Daniel , Valcarce-Torrente Manel , Amaya-Sánchez Blanca Esneda , Rojas-Núñes Claudia Fernanda
Published: December 2024

Sports organizations, to be profitable and competitive, become structures that demand the integration of competent personnel with certain characteristics and specific attributes determined by the job profile. This position rests on the purpose of productivity through good performance to fulfill the mission, vision, policies, goals, or objectives of the organization. Preceding from the above, there is diversification regarding the competencies, attributes, elements, and operational components that a sports manager must adopt to practice their profession successfully. In this sense, the aim of this study is to determine the elements and ideal holistic components that integrate the competencies and job profiles of the sports manager in the professional context. The research methodology uses nine variables in three dimensions: one related to six levels of mastery in sports management, another that refers to competencies, and one more that focuses on the job profile, resulting in 15 specific traits that a sports manager must develop to be professionally competent.
Do rising interest rates matter for bank profitability? Evidence from Portuguese banks
Authors: Pires Clara , Borralho Carlos , Cantarinha Ana
Published: December 2024

The purpose of this paper is to analyse the profitability determinants of seventeen banks operating in Portugal from 2013 to 2023. The banking market has changed significantly, particularly since 2021, when Euribor grew rapidly to control inflation target. Methodologically, a hypothetical-deductive approach was used based on panel data collected from banks' published accounts. To generate results, grouped ordinary least squares were applied, as the Breusch-Pagan test confirms homoscedasticity, an essential assumption in this regression model. Internal variables considered include credit quality, capital adequacy, management quality, financial margin, and bank size, alongside an external variable, the Euribor. The findings reveal that credit risk, capital adequacy, management capacity, and Euribor are the most statistically significant for both return on equity and return on assets, with Euribor emerging as the greatest statistically significant variable. The analysis of Euribor as an explanatory variable represents the key contribution of this study relative to the existing and reviewed literature.
Exploring determinants of VAT gaps using structural equation models: a MIMIC approach
Authors: Hasíková Iva
Published: December 2024

This study explores the estimation of the VAT gap using the Multiple Indicators and Multiple Causes (MIMIC) model, a specific type of structural equation model. The VAT gap, a significant indicator of tax revenue loss and inefficiency in VAT collection, is treated as a latent variable driven by various causes and reflected through specific indicators. Drawing on data from European countries, the model incorporates variables such as economic openness, government spending, corruption perceptions, and the e-government development index, each serving as proxies for underlying VAT collection challenges.   This study presents a first-time application of the MIMIC model to the Czech Republic, estimating the VAT gap of 2003 – 2020 and revealing fluctuations between 27 % and 35 % of total tax liability, with stabilization at 31 % since 2016.  The findings underscore policy areas for potential improvements in VAT compliance and collection efficiency, particularly through enhanced digitalization efforts and governance quality in tax administration by highlighting key factors contributing to the VAT gap.

Por ello, se han generado un importante número de resoluciones judiciales que valoran la colisión entre los derechos fundamentales al honor y las libertades de expresión e información en el deporte, cuya solución presenta particularidades interpretativas que justifican su precisión y el presente trabajo, para cuya comprensión adecuada es necesaria una previa exposición de los requisitos generales de los derechos fundamentales en litigio, tras lo cual se procede a desarrollar específicamente la colisión en la materia apuntada, siendo para ello esencial el estudio de la doctrina y jurisprudencia existente.
Implications of the COVID-19 Pandemic on the Current & Future Health of Youth Athletes via the Ecological Model for Health Promotion
Authors: Disanti Justin , Janosky Joseph , Oliver Gretchen , Jones David , Ulman Sophia
Published: December 2024

The participation limitations and experiential challenges stemming from the COVID-19 pandemic threatened the potential for youth sport participation to positively impact the multidimensional development of adolescent athletes. As society moves on from the novel conditions of the pandemic, it is important to take stock of the deficits that adolescent athletes and their supporting stakeholders experienced during this time, while also planning productive steps to learn and grow from this experience. Thus, the purpose of this paper was to conduct an evidence-based review of existing literature of this topic, purposefully organized through the lens of the Ecological Model for Health Promotion. By identifying emerging trends, gaps, and interactions of between each level of this model (i.e., intrapersonal, interpersonal, organizational, community, public policy) in relation to literature related to youth experiences during the COVID-19 pandemic, several promising avenues for future research inquiry and practical application are proposed. Through this approach, the paper aims to assist in better embodying a systematic approach that targets areas of deficit and needs that were uncovered or exacerbated by the pandemic.
Beyond the Surface: Exploring the Mind-Skin Dynamics of Psychodermatology
Authors: Criton V. J. , Tharakan Ann
Published: December 2024

Psychodermatology is an emerging interdisciplinary field that combines dermatology and psychiatry, focusing on the complex interactions between psychological factors and skin disorders. Despite its significance, this area has historically received limited attention due to inadequate training for healthcare professionals. The field is evolving, acknowledging that biological, psychological, and social elements contribute to skin disease development. Recent studies have explored the connections between the skin and nervous system, revealing how these interactions manifest in various skin conditions. Although classifications for psychodermatological disorders exist, there is no consensus on definitions. Many dermatology patients experience secondary psychiatric issues, which are frequently overlooked. It is crucial for dermatologists to be equipped to initiate basic pharmacological treatments, understand various non-pharmacological options, and know when to refer patients to psychiatrists. An integrated approach involving dermatologists, psychiatrists, and psychologists is essential for effectively addressing these complex disorders.

The authors recount the ways in which a COVID-19 vaccination campaign that explicitly embraced strengths-based community engagement moved further away from implicitly deficit-based data and assessment strategies. The conceptual framework was developed over several years in explicit confrontation with difficulties in implementation of various earlier projects, and the vaccination campaign was an important but not final step. The paper explains the driving philosophical commitments of the project and its expanding commitment to a vision of embedded community health workers (CHWs) as the mechanism for creating visibility into the dynamics of communities as they develop in terms of their own strengths and confront barriers to better health outcomes. This paper is written from the perspective of the management team and describes how the CHWs were supported and how they facilitated engagement with community members as a precursor to the vaccination decision. Some examples of CHW interactions within their communities are provided, as still preliminary steps toward a fully strengths-based approach to community data, but the authors recognize serious shortcomings in the highly individualized approach to data collection and interpretation, especially as researchers will require more sophisticated ways to model community dynamics at larger scales.
Therapeutic implications of interferon tau in medicine
Authors: Morales Victor
Published: December 2024

Interferon tau has been described as a cytokine associated with the pregnancy recognition signal in ruminants. It is structurally and functionally related to type I interferons and binds to the same receptor, but unlike other interferons, it is not inducible by viruses. Interferon tau is less toxic in vitro and in vivo than interferon alpha and Interferon beta even at high concentrations and displays high species cross-reactivity. This review describes the properties of Interferon tau and its applications in health. We emphasize the antiviral, antiproliferative and anti-inflammatory properties of interferon tau, as well as its effects in mitigating diabetes, obesity, autoimmune diseases, and anti-cancer. Therefore, interferon tau has great potential as a promising therapeutic agent with low cytotoxicity particularly for the treatment of infections and chronic diseases, cancer, and autoimmune disorders with application in health.

Purpose: To determine in a cohort of 69 African patients with large optic discs and large optic cups, that proportion of patients with physiologic cupping (normal eyes) misdiagnosed as glaucomatous. To evaluate the possible relationship between optic disc size and central corneal thickness.

Method and design: A case series of 69 African patients with large optic discs (vertical disc height measuring >1.8mm) and large optic cups (vertical cup to disc ratio ≥0.6) was evaluated to determine what proportion had glaucoma and what proportion was normal. Patients categorized as normal were further evaluated to determine what proportion were previously misdiagnosed and treated for glaucoma. Patients with a suspected diagnosis of glaucoma, normal tension glaucoma or primary open angle glaucoma were recruited from the glaucoma clinic at St John Eye Hospital in South Africa.

Outcome measures included corrected vertical disc height, vertical cup to disc ratio, intraocular pressure, central corneal thickness, retinal nerve fibre layer analysis and visual fields.

Results: Sixty-nine African patients (138 eyes) with large optic discs and large optic cups were evaluated. 41 patients (59%) were females and 28 (41%) were males. The mean age was 56 years. Of the 69 patients, 51 (74%) had physiologic cupping (normal eyes) and 18 (26%) patients had glaucoma. Of the group of 51 patients with physiologic cupping, there were 9 patients who were previously misdiagnosed with glaucoma and who had received treatment.

Vertical disc height ranged between 1.9 and 3.2 mm (mean±SD, 2.3±0.26mm). The distribution analysis of the vertical disc height measurements noted the largest cluster around 2.3mm. The central corneal thickness ranged between 454µm and 618µm (mean±SD, 516±37um). 107 (77.5%) of the 138 eyes had central corneal thickness less than 544µm.

Conclusion: Large optic cup to disc ratio in relation to large disc size can be normal. It can be misdiagnosed as glaucomatous if objective retinal nerve fibre layer analysis is not carried out. In this study, 9(18%) patients from a group of 51 patients with physiologic cupping were misdiagnosed as glaucomatous. There was no linear correlation between central corneal thickness and vertical disc height in this study. Pearson's correlation coefficient was 0.13. The majority (77.5%) of eyes had thin corneas. Central corneal thickness less than or equal to 544µm.
Promoting scientific software quality through transition to continuous integration and continuous delivery

Published: December 2024

Software quality has been an issue for decades in many areas of scientific modelling for environment applications. Much of the software that has been developed is well-suited to supporting research investigation and application in one-off curated application environments, such as delivering solutions through community-based participatory approaches. However, when releasing the software into constrained production environments, with everyday operational challenges such as missing data, unintended user inputs, variable data quality, and values outside the bounds of those previously tested, lacks in software quality can become apparent. The lacks can result in lost time and effort to get the model running again, loss of trust in the model by users and, potentially, cessation in model use, and early and unexpected end-of-life. There have been many efforts through the years to encourage improved software quality, through approaches such as test-driven development, paired programming, more rigorous documentation, and better and broader user acceptance testing. The basis of many of these approaches is the art and science of software testing, through the whole development chain from unit testing, regression testing, integration testing, functional testing and to user testing. Continuous Integration/ Continuous Development (CI/CD)/ Continuous Deployment uses an automated or semi-automated process pipeline that promotes or progresses software through various stages of 'readiness' in different system realms, from development to testing to production. Faithful application of CI/CD promotes good quality software by requiring the software to pass a series of pre-determined tests before it is accepted into the next realm. Models must meet quality levels and pass automated tests to be able to be promoted. Additionally, governance gateways are used to check non-automated workflow components, such as manual testing. This paper explores the challenges and lessons learned in adoption and application of secure CI/CD in an operational environmental modelling enterprise, and suggests a minimum viable good practice approach for application to scientific environmental modelling.
Lo curatorial por un tránsito hacia el habitar-se la tierra
Authors: Montalvo-Senior María Camila
Published: December 2024

Este artículo es una reflexión sobre la participación de los colectivos indígenas en el 46 Salón Nacional de Artistas (46SNA) 2021-2022—el SNA es el evento artístico más antiguo del país, organizado por el Ministerio de Cultura de Colombia. Se señalan los procesos de hacer de los colectivos junto con la tierra, desde la perspectiva de las experiencias estéticas cotidianas. Lo anterior se contrapone desde y en las tensiones de los mundos que habitan el evento artístico nacional: el mundo Estatal, el mundo administrativo, el mundo del arte y el mundo indígena. A partir de esta reflexión, que hace parte de un ejercicio curatorial, se proponen posibles rutas para un tránsito onto- estético-político desde los muchos mundos hacia el habitar-se la tierra.

Escherichia coli small heat shock proteins, IbpA/B, function as molecular chaperones and protect misfolded proteins against irreversible aggregation. IbpA/B are induced during overproduction of recombinant proteins and bind to inclusion bodies in E. coli cells. We investigated the effect of DeltaibpA/B mutation on formation of inclusion bodies and biological activity of enzymes sequestered in the aggregates in E. coli cells. Using three different recombinant proteins: Cro-beta-galactosidase, beta-lactamase and rat rHtrA1 we demonstrated that deletion of the ibpA/B operon did not affect the level of produced inclusion bodies. However, in aggregates containing IbpA/B a higher enzymatic activity was detected than in the IbpA/B-deficient inclusion bodies. These results confirm that IbpA/B protect misfolded proteins from inactivation in vivo.

Nowadays, scientists may learn a lot about the organisms studied just by analyzing their genetic material. This requires the development of methods of reading genomes with high accuracy. It has become clear that the knowledge of the changes occurring within a viral genome is indispensable for effective fighting of the pathogen. A good example is SARS-CoV, which was a cause of death of many people and frightened the entire world with its fast and hard to prevent propagation. Rapid development of sequencing methods, like shotgun sequencing or sequencing by hybridization (SBH), gives scientists a good tool for reading genomes. However, since sequencing methods can read fragments of up to 1000 bp only, methods for sequence assembling are required in order to read whole genomes. In this paper a new assembling method, based on graph theoretical approach, is presented. The method was tested on SARS-CoV and the results were compared to the outcome of other widely known methods.
