Organizational Support and Servant Leadership: the Mediating Role of Work Motivation and Integrity in Work Productivity
Authors: Andriansyah Muhammad , Rubini Bibin , Setyaningsih Sri
Published: December 2024

This research aims to identify the optimal strategy to enhance the work productivity of lecturers at Muhammadiyah University Jakarta by reinforcing organizational support, servant leadership, work motivation, and integrity. Employing a quantitative approach, this study distributed a survey to 164 lecturers. The data were analyzed using path analysis to evaluate the direct and indirect relationships among variables and the SITOREM method to pinpoint indicators requiring improvement or development. The findings demonstrate that organizational support and servant leadership significantly and directly impact work productivity. Additionally, their effects are partially mediated by work motivation and integrity. However, the direct influence of organizational support and servant leadership outweighs the indirect effects mediated by motivation and integrity. This suggests that while motivation and integrity are important, strengthening organizational support and servant leadership yields a more substantial impact on productivity. To optimize productivity, weaker areas such as economic added value and fairness in rewards need improvement. Specific attention should also be given to indicators such as cost efficiency and accountability. Organizational support can be enhanced by promoting fairness in reward distribution, increasing involvement in decision-making, ensuring resource availability, and fostering supportive supervision. The implications of this study provide practical guidance for colleges and universities aiming to improve lecturers’ productivity. This research serves as a valuable reference for academic institutions striving to create a supportive environment that fosters continuous productivity improvement among their staff, ultimately contributing to institutional success and societal impact.

La opacidad del poder
Authors: Schmich Niklas
Published: December 2024

Mientras en los debates públicos sobre la cultura digital se hace un llamado a la transparencia, la semántica histórica del secreto y sus múltiples funciones políticas demuestran que el concepto suele implicar una reducción de complejidad. Con el nacimiento del Estado moderno, se produce un cambio de paradigma: la connotación religiosa y cosmológica del misterio pasa a la técnica política del secreto. En la época moderna, el cálculo racional detrás del secretismo político se convierte en un dispositivo estratégico de una raison d'État orientada a preservar y ampliar el poder. Esta transformación ha dado lugar a que el Estado, al operar en secreto, se vuelva vulnerable a una interminable cascada de relatos conspirativos sobre sus actividades, tanto por teóricos de la conspiración que utilizan medios alternativos como por opositores políticos que respetan las normas del debate democrático. Tras indagar en la relación entre los secretos de Estado y los relatos de conspiración, este ensayo analiza ficciones políticas de dos escritores argentinos, Jorge Luis Borges y Ricardo Piglia, que narran la impotencia ante la opacidad del poder de una soberanía cuya conspiración impregna el discurso formal estético de los propios relatos, subrayando así la capacidad de la ficción para analizar la lógica secreta de las conspiraciones políticas.
Otros actores de la diplomacia veneciana. Los residentes en Nápoles durante la Guerra de Candía (1645-1669)
Authors: Quiles Albero David
Published: December 2024

El objetivo de este artículo es señalar la relevancia de los residentes de la República de San Marcos en Nápoles dentro de las complejas y oscilantes relaciones hispano-venecianas durante el siglo XVII. Nos centraremos en las décadas centrales de la centuria, con el fin de comprobar como el inicio de la Guerra de Candía dio paso a una nueva fase en los contactos entre ambas potencias, en la que lograr el envío de las galeras de Nápoles y Sicilia al Mediterráneo oriental se tornó en uno de los principales desafíos de la diplomacia veneciana.
De ahí la importancia de la actuación de su residente en la corte partenopea, cuya intermediación era fundamental para que las escuadras hispanas acudieran en su auxilio. A fin de cuentas, de la predisposición del virrey en esta materia –cuya autonomía comprobaremos en las siguientes páginas– dependía en última instancia el envío de los socorros deseados a Candía.

Authors: Llave Angulo Irvin Luis
Published: December 2024

Objetivo: Determinar o nível de relação entre a gestão pública e os conflitos sociais no Estado peruano durante o período de 2021-2023. Métodos: O estudo adotou uma abordagem quantitativa e relacional, com um desenho não experimental e aplicado. Foi realizada uma revisão documental dos relatórios emitidos pela Ouvidoria e pelo Conselho de Competitividade Privada entre 2021 e 2023. O coeficiente Rho de Spearman foi utilizado para avaliar a relação inversa significativa entre o Índice de Gestão Pública Regional e os níveis de conflitos sociais registados durante os 36 meses analisados. Resultados: Há uma relação inversa significativa entre a gestão pública e os níveis de conflito social. Essa relação foi mais evidente em regiões remotas, onde o desempenho ruim da governança regional gerou valor público limitado em quatro pilares principais: acesso a serviços públicos, educação, saúde e instituições. Conclusão: O baixo desempenho na gestão de políticas públicas relacionadas aos quatro pilares fundamentais intensifica a proliferação de conflitos sociais, especialmente em regiões distantes da capital do país. Isso se deve à pouca atenção do Estado ao desenvolvimento sustentável e descentralizado nessas áreas.

In May 2024, extensive flooding impacted multiple cities in Rio Grande do Sul, Brazil, including the capital, Porto Alegre. This research evaluates the potential radiological and nuclear hazards resulting from these floods. 106 facilities that use radioactive materials in nearby regions were identified, of which 30 are located in the regions of interest, categorized based on IAEA risk standards. The flooding compromised containment and monitoring systems, heightening the risk of exposure to various hazardous materials, including radioactive substances. The floods affected high-risk sites in São Leopoldo and Canoas and moderate-risk sites in Porto Alegre and São Leopoldo. The study underscores the necessity of enhancing disaster preparedness and response systems to safeguard public health and the environment.
Predicting dynamics from structure in a sodium silicate glass
Authors: Christensen Rasmus , Smedskjaer Morten M.
Published: December 2024

Understanding the dynamics of atoms in glasses is crucial for unraveling the origin of relaxation and the glass transition as well as predicting transport properties. However, identifying the structural features controlling atom dynamics in glasses remains challenging. Recently, machine learning models based on graph neural networks (GNNs) have successfully been used to predict future dynamics, but these prior studies focused primarily on model systems such as Kob–Andersen-type Lennard–Jones mixtures. This study investigates the use of local descriptors, GNN models, and molecular dynamics simulations to clarify the atomics dynamics in a realistic glass system (sodium silicate) across varying time scales. By harnessing the capabilities of different structural representations, we develop effective models for predicting the dynamics of sodium ions within the glassy silicate network, based solely on the initial atom positions. We further demonstrate the viability of our approach through comparison to previously proposed methods. Our findings pave the way for designing new glass formulations with tailored dynamical properties (e.g., as glassy electrolytes for batteries).

Impact statement

Glass science has long grappled with understanding the fundamental nature and origin of glassy dynamics. The governing principles of atomic dynamics in glasses remain elusive as it is not obvious what to look for in the glass structure. While previous studies have focused on simplified model systems, we demonstrate for the first time that machine learning models can be used to accurately predict multi-time scale atomic dynamics in a complex oxide glass (sodium silicate) from the static atomic structure. By comparing different machine learning architectures, we establish that graph neural networks outperform conventional structural descriptors for dynamics prediction, with graph representations being able to effectively capture the complex multibody correlations that govern dynamics. Our findings show that the future dynamics in oxide glasses on time scales up to nanoseconds are at least partially encoded in the initial glassy configuration itself, showing that glassy dynamics is not a completely stochastic process. The capability to predict dynamics from structure has major implications as it could provide new tools for rational design of glassy materials with tailored dynamical properties and functionalities, possibly accelerating development of advanced glasses for applications in areas such as solid-state batteries and nuclear waste immobilization.

Materials and methods. The subject of this article is the determination of the approach to the technological process validation of manufacturing medical devices using the example of injectable implants based on cross-linking hyaluronic acid, based on the experience of batch production of the specified type of products on an industrial scale and the regulatory requirements of Ukraine and the European Union.
Results. The article presents information about the nature of hyaluronic acid, its structure, sources and methods of production, and the scope of application.
Determination of critical points of the technological process was carried out by the method of risk assessment using the approach of forming the Ishikawa diagram, i.e. "analysis of cause-and-effect relationships ".
The main stages of the analysis of causal relationships are the following:
– determination of the process that is subject to analysis (obtaining high-quality finished products) and sub-processes that have an impact on the final result;
– determination of the main categories of impact on the process, displayed by blocks on the Ishikawa diagram.
The result of such an analysis is displayed in the form of the above-mentioned diagram Ishikawa ("fishbone").
Sub-processes that have the main influence on it were determined. These elements are the critical points that will be subject to validation. The impact of each of these elements, their key parameters and permissible operating ranges are described in the article.
Conclusions. The sub-processes that have the main impact on the technological process of manufacturing the medical device are identified. These elements are critical points that are subject to validation. The article describes the impact of each of these elements, their main parameters and permissible operating ranges, and also presents the validation process and confirmation of the validity of the corresponding technology

Explainability in Artificial Intelligence Models for Business Intelligence: Addressing NonTechnical Decision Makers’ Needs
Authors:   (Alumnus) University of Maiduguri, Dangote Business School, Bayero University Kano, Nigeria, Jidda Ahmad
Published: December 2024

Artificial Intelligence (AI) is transforming Business Intelligence (BI) by helping organizations make
better decisions through predictive and prescriptive insights. However, many AI models are complex and difficult to
understand, especially for non-technical decision-makers. This creates challenges in trusting and using AI-driven
outputs effectively. To address this, we propose an Explainable AI (XAI) framework specifically designed to make AI
insights clearer, more transparent, and easier to act on for business users. To address these issues, this article proposes a
tailored Explainable AI (XAI) framework specifically designed for BI contexts. The framework incorporates five key
components: interpretability guidelines, visualization techniques, natural language processing (NLP) interfaces, bias
detection and mitigation tools, and role-specific customization. Conceptual validation through hypothetical scenarios in
industries such as telecom, banking, and retail, we demonstrate how the framework reduces confusion, builds trust, and
helps decision-makers confidently use AI to improve outcomes. This work relies on secondary data from reputable
academic research and industry case studies to propose the framework. While this framework shows significant
benefits, we acknowledge some limitations, such as the need for high-quality data, the resources required for initial
setup, and frequent updates in fast-changing business environments. Future research should focus on creating advanced
visual tools, real-time bias detection systems, and ways to measure the success of explainability frameworks. By
bridging the gap between AI’s technical complexity and users’ understanding, this framework empowers decisionmakers to use AI insights effectively, making organizations smarter, more ethical, and more data-driven.

Parallel Mediating Role of FoMO and Mental Well-Being Between Entrapment and Psychological Distress
Authors: Akyıl Yusuf , Oral Tuncay , Erdinç Beste
Published: December 2024

Individuals may occasionally experience psychological distress and entrapment, which is not a desirable situation. Psychological distress is defined as a state of emotional suffering characterized by symptoms of depression and anxiety, whereas entrapment is defined as negative feelings caused by an unsuccessful struggle and the belief that the defeating situation cannot be resolved or escaped. Currently, rapid developments have brought along with them the fear of missing out on these developments. In order to minimize these undesirable situations in human life, this study aims to test the mediating role of FoMO and mental well-being between psychological distress and entrapment. The relationships between these variables have not been investigated before and this study is the first to investigate the relationships between the mentioned variables. 64 male and 420 female participants over the age of 18 participated in the study voluntarily. To evaluate the related variables, Entrapment Scale, Fear of Missing Out Scale, Mental Well-Being Scale, and the Kessler Psychological Distress Scale were used. Structural Equation Modeling was used to conduct mediation analysis on the study's data. The findings revealed that FoMO and mental well-being acted as parallel mediators of psychological distress and entrapment. In other words, psychological distress predicts entrapment both directly and through fear of missing out and mental well-being. In the model, psychological distress positively predicted entrapment and FoMO, but mental well-being negatively predicted. The direct relationship between psychological distress and entrapment, through related mediators, significantly aids individuals in managing negative experiences such as psychological distress, entrapment, and FoMO more effectively. The current research is a quantitative model explaining the relationship between psychological distress, entrapment, fear of missing out and mental well-being. The findings are discussed within the scope of the relevant literature.
Price Forecasting of Feed Raw Materials Used in Dairy Farming: A Methodological Comparison
Authors: Kılınç Yılmaz Merve , Şahin Yusuf , Oruç Kenan Oğuzhan
Published: December 2024

Milk is among the products of strategic importance for countries due to its nutritional value and being a priority foodstuff. Feed raw materials are one of the most important input items in the dairy cattle sector. Ensuring the balance of milk/feed parity is of great importance for producers to maintain their activities and profitability. In countries like Turkey, where inflationary effects are observed, the prices of feed raw materials are not stable. In an environment of high price fluctuations, forecasting feed raw material prices for producers is of vital importance for future planning. In this study, price forecasting of 43 feed raw materials, which are used extensively in the ration preparation process in the dairy cattle sector, was carried out. The performances of 11 methods based on Time Series, Statistics and Grey System Theory are compared. After the comparison using model success criteria, it was found that the DGM (1,1) method forecasts more effectively than Exponential Smoothing and Regression models as well as other Grey Forecasting models. Based on MAD, MSE and MAPE values, it is concluded that Grey Forecasting methods can be a good alternative for price forecasting of feed ingredients.
Effect of surfactant on bubble rising velocity in viscous liquid
Authors:   Tomsk State University, Borzenko Evgeniy I. , Usanina Anna S. ,   Tomsk State University, Shrager Gennadiy R. ,   Tomsk State University
Published: December 2024

This paper presents a study of the rising velocity of a single gas bubble in a viscous liquid with a dissolved surfactant and the characteristics of hydrodynamic and diffusion processes on the free surface under conditions of dominance of viscous friction forces over gravitational forces. The original computational method accounting for the surface tension forces and the Marangoni effect caused by the surfactant concentration gradient along the boundary is presented. The mathematical formulation of the problem includes the equations of motion, continuity, and convective diffusion. The boundary conditions on the free surface are written with account for the discontinuity of shear and normal stresses. The surfactant transport on the surface is described in accordance with the Langmuir model. The free surface motion is carried out in compliance with the kinematic condition. The approach is based on the simultaneous use of the finite volume method and the method of invariants, which allows one to explicitly identify a free surface with valid natural boundary conditions. The effect of concentration of surfactants on the characteristics of hydrodynamic and diffusion processes is demonstrated.
Modeling of inhomogeneous deformation of porous ceramics using gaussian random fields
Authors:   Institute of Strength Physics and Materials Science of the Siberian Branch of RAS, Zimina Valentina A.
Published: December 2024

In this paper, the inhomogeneous distribution of strain in porous ceramic specimens under diametral compression is numerically analyzed using a stochastic representation of the material structure. Models of the structure of porous ceramics are based on a probabilistic description of mechanical properties of ceramics using Gaussian random fields. Numerical simulation is performed for zirconium ceramics with porosities of 4 and 42 %. In the framework of the modeling method used, different porosities of ceramics are taken into account in terms of effective mechanical properties and parameters of the covariation matrix of a random Gaussian field. The simulation of the diametral compression of porous ceramic specimens is carried out in a two-dimensional formulation under plane-strain conditions. The loading is set in the upper and lower parts of the specimen near the central vertical axis through the velocities of the selected nodes. Distributions of the strain tensor components for the studied specimens are analyzed, and their evolution in the central part of the specimens is studied in detail. It is shown that the strain is localized in the form of bands of different sizes and intensities inclined at an angle of approximately 45° to the loading axis. The difference in the strain distributions for the specimens with various porosities in the performed calculations is a result of different models of the inhomogeneous structure. The specimen with a porosity of 4 % is characterized by a greater number of heterogeneous regions of smaller size compared with a specimen with a porosity of 42 %. The proposed method of describing the material structure allows one to obtain various types of inhomogeneous strain distributions under diametral compression, as well as to control the size of heterogeneous regions in the strain distributions.

Published: December 2024

This paper presents the verification results for a one-dimensional computer mathematical model of longitudinal-transverse vibrations of an artillery gun barrel under internal pressure loading and the thermal effect of powder gases based on a comparison with a three-dimensional problem solution. The mathematical model takes into account gravity, non-uniform thermal loading, and pressure distribution along the barrel length on firing. A comparison of one-dimensional and three-dimensional modeling results for vibrations of a cylindrical barrel with variable annular cross-section and a cylindrical barrel of variable annular cross-section with account for manufacturing tolerance of the classical barrel and the barrel with stiffeners is carried out. The comparison shows that the onedimensional model gives a reasonable approximation for barrel oscillations with a deviation from the three-dimensional model case ranging from 2.9% to 12.5%. Therewith, the time required to calculate the vibrations of the barrel in a one-dimensional formulation is significantly reduced (by 4-5 orders of magnitude) as compared to a three-dimensional formulation.

Moreover, significant differences were observed in problem solving skills based on educational status, seniority and type, but no significant differences were found according to gender or teaching specialization. Additionally, technostress levels varied significantly across gender, seniority, teaching specialization, educational status and school type. The study further identified a significant negative correlation between technostress and problem solving skills, suggesting that technostress has a notable detrimental effect on teachers' problem solving abilities. Based on the findings obtained, recommendations have been made.

Severe acute pancreatitis (SAP) is one of the leading causes of hospital admissions for gastrointestinal diseases, with a rising incidence worldwide. Intestinal microbiota dysbiosis caused by SAP exacerbates systemic inflammatory response syndrome and organ dysfunction. Fecal microbiota transplantation (FMT) has emerged as a promising therapeutic option for gastrointestinal diseases. In this study, fecal samples from healthy, control, and FMT-treated groups were analyzed using 16S rRNA sequencing to assess microbiome abundance and diversity. Composition and functional prediction analyses were conducted to explore the mechanisms underlying FMT in SAP. FMT significantly improved clinical parameters in SAP patients, including leukocyte count, C-reactive protein (CRP), neutrophil granulocyte count, lactate dehydrogenase (LDH), and calcitonin (P < 0.05). Organ failure rates significantly increased in the control group but decreased in the FMT group after treatment (P < 0.05). Fecal microbiota sequencing revealed that FMT significantly upregulated the abundance of Bifidobacterium longum among all SAP patients (P < 0.05). Receiver operating characteristic (ROC) curve analysis indicated that Bifidobacterium longum might play a critical role in the efficacy of FMT, with an area under the curve (AUC) value of 0.84. Additionally, there was a negative correlation between Bifidobacterium longum abundance and procalcitonin (PCT) levels, as well as a negative correlation between Escherichia coli abundance and both CT and Ca values (P < 0.05). The relative abundances of Bifidobacterium longum and Escherichia coli were significantly higher in the FMT group compared to the Bifidobacterium triple viable group (P < 0.05). In conclusion, this research supports FMT as a safe and effective intervention for treating SAP patients.

The objective of this study was to know the distribution of winning strokes and errors in padel and to analyze the differences between male and female gender. A total of 1,068 strokes were analyzed corresponding to 8 matches (4 men's and 4 women's) of the Valencia Master tournament of the official World Padel Tour 2021 circuit. The matches were analyzed through systematic observation. The results showed that there are no significant differences between genders in the area of ​​the court in which the players make the last shot of the point in padel (winner or error). Both men and women make approximately 40% of the point-ending shots from the middle of the court. Furthermore, men make 22.9% more winning shots bringing the ball into their own court than women, and women make 29% more winning shots with double bounces than men. On the other hand, there are no differences between men and women in the distribution of errors in professional padel and approximately half of the errors in padel occur by hitting the ball against the net, in both men's and women's padel. These data will serve as a reference for coaches and players to design exercises adapted to the demands of the competition.

Di Malaysia, penggunaan media sosial telah diiktiraf sebagai strategi yang relevan dan efektif untuk kempen pemasaran sosial dan membolehkan penggerak politik mencapai khalayak yang luas. Platform media sosial memainkan peranan yang sangat penting dalam pola ‘diet’ media dikalangan pengundi digital asli (digital native) dan dapat mendorong keterlibatan dalam kempen pilihan raya. Pengundi baharu yang menggunakan platform ini lebih terdedah kepada komunikasi langsung dari aktor politik daripada pengundi berpengalaman, sementara kandungan dari berita di platform media sosial memainkan peranan yang sama dalam pola ‘diet’ media kedua-dua kumpulan tersebut. Kajian ini memfokuskan kepada pembingkaian kandungan hantaran kempen politik di media sosial milik calon Perikatan Nasional (PN) negeri Selangor yang bertanding sepanjang tempoh berkempen PRU15. Kajian ini bertujuan untuk mengenal pasti isu khusus berunsur perkauman dan agama yang telah digunakan dalam kempen pilihan raya dan bagaimana ia dibingkaikan melalui kandungan hantaran di saluran media sosial seperti Facebook, Instagram, Twitter, TikTok dan YouTube. Dengan menggunakan kaedah analisis kandungan, pengkaji telah membuat analisis untuk mengenal pasti isu khusus dan cara ia dibingkaikan. Hasil kajian mendapati antara isu khusus yang berkait rapat dengan perkauman dan agama adalah Teraju dan Ekuinas, pemimpin beragama, PN dan agama Islam, peruntukan usahawan Bumiputera, Sisters In Islam, Bahasa Melayu, dasar afirmatif, ICERD, pengundi India dan transgender. Manakala bingkai moral merupakan bingkai paling utama digunakan diikuti oleh bingkai tanggungjawab, bingkai kesan ekonomi, bingkai kepentingan manusia dan bingkai konflik.

The US regards China as a challenger to its dominant global order. China is no longer satisfied with America dominating the world as the single superpower. The US has relied on its global-leading film industry, Hollywood, to promote soft power and accomplish cultural hegemony on the global stage. Compared to the US, China needs more international attraction from the perspective of soft power and its film industry. Meg 2: The Trench can be seen as an attempt at cooperation in competition. This study focuses on the recent Sino-US co-production, Meg 2: The Trench, released in 2023, in the political context of competition between the two countries. The research objective is to evaluate the Chinese culture, values and foreign policies Meg 2: The Trench promotes. The central problem to be addressed in this research is the Chinese soft power promotion of the recently released Sino-US co-production Meg 2: The Trench. This research employed Algirdas Julien Greimas’s Actantial Model (1983) to critically analyse the portrayal of the characters and narratives in Meg 2: The Trench with close textual analysis as the method for this research. We found that Hollywood made concessions regarding its values propaganda. Meg 2: The Trench emphasises China`s official culture, values and foreign policies, but its essence is individual heroism.
Keywords: Soft power, cultural hegemony Sino-US co-production, Sino-US relations, Meg 2: The Trench, Actantial Model.
