Impact of Entrepreneurial Leadership on Teacher Creativity: The Mediating Role of School Culture in Indonesian Public Senior Secondary Schools
Authors: Machali Imam , Murfi Ali , Yani Zhou
Published: January 2025

Purpose – This study explores the relationship between entrepreneurial leadership, school culture, and teachers' creativity within public senior secondary schools in Yogyakarta, Indonesia. The research aims to determine whether entrepreneurial leadership directly influences teacher creativity or whether its impact is mediated through the school culture.
Methods/Design/Approach – A quantitative survey methodology was employed, collecting data from 136 teachers across multiple schools in Yogyakarta. Structural Equation Modelling Partial Least Squares (SEM-PLS) was used to analyze the relationships between the variables, including entrepreneurial leadership, school culture, and teachers' creativity.
Findings – The results reveal that entrepreneurial leadership does not directly enhance teachers' creativity within the studied context. However, entrepreneurial leadership significantly contributes to a conducive school culture, which in turn positively impacts teachers' creativity. The study identifies school culture as a critical mediator, suggesting that the influence of entrepreneurial leadership on creativity is indirect and operates primarily through the development of a supportive environment.
Originality/Value – This study provides new insights into the applicability of entrepreneurial leadership in educational settings, particularly in Indonesia. It challenges the assumption that entrepreneurial leadership directly fosters creativity and underscores the importance of school culture as a mediator.
Practical Implications – The findings emphasize the importance of developing a supportive school culture to foster creativity among teachers. Educational leaders should focus on building environments that encourage innovation, collaboration, and growth. Policymakers can support this by integrating entrepreneurial leadership practices with strategies to cultivate a positive school culture, enhancing overall teacher creativity and effectiveness.
Keywords Entrepreneurial leadership, school culture, teacher creativity, educational leadership, Indonesian schools.

A DISPUTA ELEITORAL ATRAVÉS DAS REDES SOCIAIS
Authors: DOURADO MANOELA
Published: January 2025

O presente artigo aborda o impacto das redes sociais na disputa eleitoral, destacando a transformação proporcionada pela Revolução Digital e a crescente importância dessas plataformas na política. Com bilhões de usuários globais e milhões no Brasil, as redes sociais se tornaram ferramentas cruciais para candidatos que buscam influenciar eleitores. Estudos mostram que quase a metade dos eleitores utilizam essas plataformas para obter informações sobre candidatos, o que denota sua importância na corrida eleitoral. No entanto, a disseminação de fake news é um problema significativo, influenciando negativamente a percepção pública e criando desafios para a Justiça Eleitoral, que tem implementado medidas regulamentações específicas para a propaganda eleitoral online. O artigo conclui que, embora as redes sociais democratizem o acesso à informação, é essencial que todos os participantes do processo eleitoral estejam cientes das normas e das consequências de práticas desinformativas para garantir eleições justas e democráticas.

Authors: Edo Abdulloh , Yasin Muhammad
Published: January 2025

Education is a key factor in encouraging social mobility in Indonesia. However, unequal access to quality education, especially in rural areas, creates significant gaps in opportunities to improve social status. This research aims to analyze the impact of gaps in educational access and family economic factors on social mobility in South Sangatta. Using a qualitative descriptive approach, data was collected through observation and in-depth interviews with various relevant informants. The research results show that limited access to adequate education in South Sangatta has a direct impact on the low level of social mobility. Children from well-off families have greater opportunities to obtain quality education compared to children from less well-off families. Family economic factors are proven to be the main determinant in the effectiveness of education as a tool for increasing social mobility. This research highlights the need for equitable access to education and economic interventions to increase social mobility in rural areas such as South Sangatta.
Makna Ungkapan “Jangan Kamu Membangkitkan Dan Menggerakkan Cinta Sebelum Diingininya (Kidung Agung 2:7b)” Dan Implementasinya Bagi Pasangan Pranikah
Authors: Intan Falensia Sambeta  , I Gede Agus Z.P.  , Riko Arnawijaya Ray
Published: January 2025

This paper explores the meaning of the phrase  "Do not arouse or awaken love until it so desires." in Song of Solomon 2:7b and its implications for premarital couples. This phrase emphasises the importance of self-control in love and desire, especially before marriage. Using qualitative methods and theological interpretation, this study explores the theological meaning of the verse and its relevance in the modern context. The results show that self-control in love, in accordance with biblical teaching, is essential to maintaining the sanctity of premarital relationships. The modern phenomenon shows that many young couples are failing to maintain this boundary, which has the potential to undermine marriage preparation and have long-term negative consequences. Therefore, applying the principles of love contained in the Song of Songs can help young couples build a strong and God-blessed marriage foundation. This study also aims to provide practical guidance for pre-marital couples in maintaining the sanctity of love and delaying physical relations until the right time according to God's will, in order to avoid temptation and build a healthy and balanced relationship.
Between Word and Body: (Re)Organ-izing the Autobiography in bpNichol’s Organ Music: Parts of an Autobiography
Authors: Brubacher William
Published: January 2025

This paper examines bpNichol’s entanglement of corporeality and textuality through his experimental intervention in the genre of autobiography, titled Organ Music: Parts of an Autobiography. By studying how his autobiography encounters morphologies organizing bodies around the penetration, entry, appropriation and mastery of female bodies, I argue that Nichol's text provides new models for writing the self, embodiment, and sexual difference. The body inscribed in the pages of the text is decentered and abstracted as it comes into contact with and contests the logics of sameness and corporeal impermeability. My work proposes that his text makes legible and resists what Luce Irigaray and Elizabeth Grosz respectively identify as heteropatriarchal “morphologies”—the meanings, vocabularies, and grammars that shape and constitute bodies.
Considerations about Materiality and the Medial Processes in the Puppet Company “Die Klappe. Das Kabarett an Fäden”
Authors: Orduño Bucio Rodrigo
Published: January 2025

This text collects some considerations of the work of the German puppet company “Die Klappe. Das Kabarett an Fäden” in the postwar period. From the study of a puppet, its morphology and its stage performance, the medial processes set in motion and promoted by its material constitution are explored, including the energetic flows that incite the act of embodiment framed by the register of the cinematographic camera. I consider the above as a reflection of the media incorporation promoted by the neo-avant-garde in the puppet theater.
The Networked Author: Looking at Contemporary Authorship Through Postdigital Comics
Authors: Busi Rizzi Giorgio
Published: January 2025

This article investigates contemporary authorship in the (global) English-speaking context, focusing on the shared creative practices of postdigital comics – those that bear the inscription of digital technologies and practices in unprecedented or renewed ways. In doing so, it proposes an original framework to discuss how the digital has brought forward novel network dynamics of comics creation beyond the single author, arguing for the identification, within this networked authorship, of (a) renewed forms and practices of ‘collective authorship,’ and (b) new types of ‘distributed authorship.’ In a conceptual reframing of this landscape, the article divides the former into ‘collaborative’ or ‘participatory’ authorship, and the latter into ‘algorithmic’ and ‘rhizomatic’ authorship, surveying and discussing their configurations.
Revisiting Post-May 1968 French Theory: Critical Thought and Data Capitalism
Authors: Taek-Gwang Lee Alex
Published: January 2025

This essay explores the critical crisis stemming from the normalization of data-driven capitalism in the neoliberal era. It proposes the concept of subjectivization of anachronism, developed by French philosophers in the 1960s, as a potential avenue for revitalizing critical thought. The rise of data capitalism, characterized by big tech-driven accumulation, emerged as a distinct mode of capitalist production during the post-war US-centric Cold War era and subsequent globalization from the 1950s onward. As artificial intelligence heralds a new technological paradigm shift, this essay examines the possibilities for critical subjectivity within this evolving landscape. By drawing on insights from 1960s French philosophy – a cornerstone of contemporary critical theory – the essay aims to reassess and reinvigorate critical discourse in the age of data capitalism.
Non-allometric expansion and enhanced compartmentalization of Purkinje cell dendrites in the human cerebellum
Authors: Busch Silas E , Hansel Christian
Published: January 2025

Purkinje cell (PC) dendrites are optimized to integrate the vast cerebellar input array and drive the sole cortical output. PCs are classically seen as stereotypical computational units, yet mouse PCs are morphologically diverse and those with multi-branched structure can receive non-canonical climbing fiber (CF) multi-innervation that confers independent compartment-specific signaling. While otherwise uncharacterized, human PCs are universally multi-branched. Do they exceed allometry to achieve enhanced integrative capacities relative to mouse PCs? To answer this, we used several comparative histology techniques in adult human and mouse to analyze cellular morphology, parallel fiber (PF) and CF input arrangement, and regional PC demographics. Human PCs are substantially larger than previously described; they exceed allometric constraint by cortical thickness and are the largest neuron in the brain with 6-7cm total dendritic length. Unlike mouse, human PC dendrites ramify horizontally to form a multi-compartment motif that we show can receive multiple CFs. Human spines are denser (6.9 vs 4.9 spines/μm), larger (∼0.36 vs 0.29μm), and include an unreported ‘spine cluster’ structure—features that may be congruent with enhanced PF association and amplification as human-specific adaptations. By extrapolation, human PCs may receive 500,000 to 1 million synaptic inputs compared with 30-40,000 in mouse. Collectively, human PC morphology and input arrangement is quantitatively and qualitatively distinct from rodent. Multi-branched PCs are more prevalent in posterior and lateral cerebellum, co-varying with functional boundaries, supporting the hypothesis that this morphological motif permits expanded input multiplexing and may subserve task-dependent needs for input association.
Fast binary logistic regression
Authors: Saran Nurdan Ayse , Nar Fatih
Published: January 2025

This study presents a novel numerical approach that improves the training efficiency of binary logistic regression, a popular statistical model in the machine learning community. Our method achieves training times an order of magnitude faster than traditional logistic regression by employing a novel Soft-Plus approximation, which enables reformulation of logistic regression parameter estimation into matrix-vector form. We also adopt the Lf-norm penalty, which allows using fractional norms, including the L2-norm, L1-norm, and L0-norm, to regularize the model parameters. We put Lf-norm formulation in matrix-vector form, providing flexibility to include or exclude penalization of the intercept term when applying regularization. Furthermore, to address the common problem of collinear features, we apply singular value decomposition (SVD), resulting in a low-rank representation commonly used to reduce computational complexity while preserving essential features and mitigating noise. Moreover, our approach incorporates a randomized SVD alongside a newly developed SVD with row reduction (SVD-RR) method, which aims to manage datasets with many rows and features efficiently. This computational efficiency is crucial in developing a generalized model that requires repeated training over various parameters to balance bias and variance. We also demonstrate the effectiveness of our fast binary logistic regression (FBLR) method on various datasets from the OpenML repository in addition to synthetic datasets.
Evaluación de la recuperación de las selvas tropicales del Parque Nacional Main Range después de los incendios forestales Black Summer 2019/20 en Australia
Authors: O’Hare Sydney
Published: January 2025

El Parque Nacional Main Range (MRNP) experimentó incendios sin precedentes y fue gravemente afectado por los incendios forestales de la temporada 2019-2020, conocidos como el “Verano Negro” o Black Summer. Esta investigación tiene como objetivo comprender cómo se recuperan las selvas tropicales de los incendios forestales severos, comparando su recuperación con la de los bosques de eucaliptos y determinando cuáles ecosistemas regionales de selva (RE) están expuestos a mayor riesgo. Se utilizó la imagen de Sentinel 2 para calcular los valores de dNBR del incendio y los tres años siguientes, validándolos mediante una prueba t emparejada para detectar cambios, con el fin de entender cuán severo fue el incendio y cómo se recuperó la selva tropical. Se descubrió que 81,28 km² se quemaron con una severidad extrema o alta, y 28,35 km² de selva tropical se recuperaron, dejando solo 0,35 km² quemados para 2022. Se determinó que el RE 12.8.4 era el más vulnerable al fuego, debido a que los 0,02 km² restantes quemados en 2022 aún mostraban quemaduras de severidad moderada o alta, lo que permite la posibilidad de transiciones comunitarias, a pesar de que solo se quemaron 2,4 km² en total. Estos resultados muestran que la selva tropical puede recuperarse de incendios extremos; sin embargo, algunos ecosistemas tardan más tiempo en recuperarse y están en mayor riesgo. Este estudio es relevante para futuras respuestas ante incendios, con el fin de priorizar áreas como el RE 12.8.4 para su protección, y además profundizar en el entendimiento de la resiliencia de las selvas tropicales ante los incendios.
Tres casos de antinomias del consumo financiero. Propuesta de solución a la luz del diálogo de fuentes
Authors: Barrientos Francisca , Cañete Rossana , Barroilhet Agustín
Published: January 2025

Este artículo aborda las antinomias que se producen en Chile entre la Ley N° 19.496, que protege los derechos de los consumidores (LPDC), y diversas leyes especiales del ámbito financiero. Estos conflictos normativos generan incertidumbre a los consumidores y a la industria financiera. La investigación identifica tres casos de conflicto normativo en créditos al consumidor, seguros asociados a créditos y la competencia para conocer de ciertos conflictos relativos a seguros, mostrando que los métodos tradicionales de resolución de antinomias son insuficientes para resolverlos. Este escenario abre la propuesta a la utilización del método del “diálogo de fuentes” como alternativa para la resolución de antinomias. Este enfoque fomenta una interpretación armónica de las normas, procurando que las normas protectoras de los derechos de los consumidores no dejen de ser aplicadas, aunque estén en distintos cuerpos normativos. El diálogo de fuentes, ampliamente desarrollado en Brasil y Argentina, tiene sustento normativo en el principio proconsumidor recientemente consagrado en Chile, y permite dar prevalencia a las normas que mejor salvaguardan los intereses del consumidor en situaciones de conflicto normativo. Este método ofrece una solución viable para integrar de manera coherente la normativa financiera con la LPDC, evitando que la fragmentación del sistema jurídico menoscabe la protección de los derechos de los consumidores.

Published: January 2025

To meet the ever-increasing demand for food, there is a huge concern about the selection of superior genotypes with enhanced resilience to abiotic stress. However, choice/selection of suitable genotype/line is complex due to significant interaction of genotypes with environmental factors. Aiming few traits for selection may simplify the statistical analysis, however selection of genotypes using multiple traits is quite difficult. Furthermore, use of any single index may bias the selection of genotypes.  Here, we proposed one method for selection of superior genotypes using combined approach of four selection indexes such as, multi-trait genotype-ideotype distance index (MGIDI), factor analysis and genotype-ideotype distance (FAI-BLUP), Smith-Hazel index (SHI) and multi-trait stability index (MTSI) under multi-environment stress conditions by using R programming. From our study, twenty random recombinant inbred wheat lines among the 220 lines developed by crossing HD3086 and HI1500 has been taken for analysis. The selection intensity (SI) was 15% for all the indexes. The lines were tested for stay-green and stem reserve mobilisation traits under control, drought, heat and combined stress conditions. Result found that RIL-10 was common to these four indexes by using venn diagram and was considered to be superior among the lines, which can perform better under multi-environment stress conditions. Thus, we recommend that combined approach of several indexes can be used a robust method for selection of ideal genotypes in wheat and other crop as well.
Fatigue Life Prediction of Wheels for CRH2 High-speed Train Due to Flexible Tracks
Authors: Rodger Murungi , Mohammedseid Awel
Published: January 2025

Wheels are some of the most vital components of a railway vehicle with respect to reliable and safe operations of the railway system. However, the wheels of the railway vehicle are routinely subjected to continuous excitations resulting from track flexibility and irregularities during the running action. Frequent subjection on the wheels results in repetitive loads and hence contributes to fatigue failure. Thus this study aims to propose a method of fatigue life prediction for wheels of high-speed trains due to irregularities and flexibility of the track and conducts an investigation about the influence at different speeds. A study on the wheel was conducted using the finite element method, SIMPACK software for dynamic performance and Matlab for irregularities.
An investigation was conducted at different speeds of operation to establish the effect on the wheels and the results indicated that as the speed of operation increases, the life of the wheels reduces significantly from  to  Hence irregularities and track flexibility are some of the most important factors which must be put into consideration to ensure a lasting service life of the wheels.

Preclinical studies of nanoparticles for pulmonary therapeutics are often performed on 2D cell cultures or in vitro models that do not include a mucus barrier. However, the mucus layer lining the lungs is an essential barrier for drugs to permeate in order to exert a therapeutic effect. Herein, the role of surface coating of lanthanide‐doped upconverting nanoparticles (UCNPs) and their interaction with the mucus barrier are explored using a patient‐derived 3D cell culture model. The upconverted emissions from the UCNPs are used to track them throughout the 3D model and study their localization as a function of administration time and mucus thickness. Positively charged, ligand‐free, and negatively charged, supported lipid bilayer‐coated UCNPs are evaluated. A substantial difference in the residence time in mucus and mucociliary clearance of each type of UCNP is observed in a realistic and relevant model. As such, these results underscore the need for preclinical investigations in tissue models, especially with respect to the surface properties of the nanoparticles under study.

Published: December 2023

Solution‐processed hole transporting layers (HTLs) not only play a crucial role in realizing high performance of organic solar cells (OSCs), but also possess excellent compatibility with low‐cost and large‐area processing methods of industrialized productions. However, the number and species of HTL materials are obviously fewer than that of electron‐transporting materials, which limits the development and application of OSCs. In particular, the large energy level difference between anode and organic active layer leads to the serious energy barrier for hole collection, bringing much difficulty in developing efficient HTL materials. In this review, it is focused on the recent advances in solution‐processed HTLs in OSCs. Initially, the working mechanism, property requirement, and existing issues of solution‐processed HTLs are systematically analyzed. Afterward, the main classes of solution‐processed HTL materials are discussed, including PEDOT:PSS, conjugated polyelectrolytes (CPEs), TMOs, and others. The structure‐property relationships of solution‐processed HTL materials are analyzed, and some important design rules for such materials toward efficient and stable OSCs are presented. Finally, a brief summary is presented along with some perspectives to help researchers understanding the challenges and opportunities in this field.

For real‐time care of metabolic diseases, it is highly demanded to simultaneously monitor metabolite content and diagnose muscle strength in a rapid and convenient way. However, such a biosensor with integrated functions of detecting chemical and biopotential signals at the same time has seldom been reported. In this work, a multifunctional biosensor, integrating the electrochemical detection of uric acid (UA) and glucose (Glu) in sweat, electrophysiological signal acquisition, and electrostimulation therapy, is designed. Hence, an electrophysiological MOF/MXene electrode is fabricated using highly conductive MXene and porous conductive metal–organic framework (c‐MOF, Ni3(HITP)2). Compared with commercial Ag/AgCl electrode, MOF/MXene electrode has lower electrode/skin interface impedance, higher stability and signal‐to‐noise (SNR). By utilizing the high charge storage capacity (CSC) of MOF/MXene electrode, it can realize muscle treatment by electrostimulation. Besides, with abundant active regions of c‐MOF, the electrode exhibits excellent electrochemical performance in detecting sweat metabolites. Multimodal signals detected by such integrated biosensors are wirelessly transmitted to a mobile terminal, showing significant potential on muscle theranostics and daily non‐invasive monitoring. Additionally, they offer timely nutritional guidance for individuals dealing with hyperuricemia or hyperglycemia.

Scalable assembly of two dimensional (2D) lamellar nanomaterials for deformable films has potential in wearable energy storage devices, but overcoming the trade‐off in mechanical and energy storage properties is a challenge. Here, a blade‐coating strategy is reported to develop highly stretchable and bendable metal‐organic frameworks/large‐sized Ti3C2Tx MXene (MOF/LMX) composite films on the pre‐stretched elastomer substrates. The LMX sheets serve as conductive scaffolds for loading the small‐sized ultrathin MOF sheets (SUMOFs), resulting in an improved tensile strength (≈97 MPa) of the films, which guarantees their structural integrity when forming a wavy structure on a relaxed substrate. In addition, SUMOFs incorporated in‐between LMX layers not only expose active redox sites by mitigating the intrinsic self‐restacking of MOF but also accelerate the electron transfer in the redox reaction process revealed through the density functional theory calculations. As a result, the composite films deliver high electrical conductivity (3244 S cm−1) and energy storage capability (1238 F g−1). When assembled into an asymmetric supercapacitor device, it also exhibits stable performances under different bending and stretching states. Thus, the development of conducting and deformable MOF‐based films with high mechanical, electrical, and energy storage properties enables their potential commercial applications for wearable electronics.

This research aims to enhance MXene (Ti3C2Tx) synthesis from MAX phases (Ti3AlC2) through a hydro‐solvothermal exfoliation process, with a focus on reducing time and temperature requirements. Prior hydrothermal studies have encountered challenges due to high reaction temperatures. In comparison to previous research, this work achieves superior results at lower temperatures. Two optimized MXene preparation routes are investigated and the etchant's impact on MXene surface chemistry is analyzed. Comprehensive X‐ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X‐ray Spectroscopy (EDS), X‐ray Photoelectron Spectroscopy (XPS), Fourier transform infrared (FTIR), Raman spectroscopy, and Atomic Force Microscopy (AFM) analyses provide insights into hydrosolvothermal synthesis (H‐Ti3C2Tx ) multilayers(ML), confirming/challenging recent spectroscopic assignments. Remarkably, hydro‐solvothermal treatment induces significant changes in surface composition, increasing hydroxyl (─OH) groups without oxidation and reducing fluorine (─F) groups on the H‐ Ti3C2Tx surface. These study's results hold promise for applications in energy storage and electromagnetic wave shielding. This research accomplishes three main objectives: i) secures hydrothermal synthesis of two‐ dimensional (2D) MXenes, ii) efficiently utilizes lithium fluroide‐ hydrochloric acid (LiF−HCl) etching for high‐quality MXene flakes with minimal defects, and iii) understands hydro‐solvothermal kinetics. This approach advances MXene synthesis with enhanced material quality and production efficiency (>98%), in a more eco‐friendly and safer manner. This eco‐conscious synthesis underscores MXene's versatility and eco‐friendly methods' significance, reshaping MXene exploration and sustainable material synthesis, with potential implications for future electrochemical applications.

Published: December 2023

The fault estimation (FE) and fault‐tolerant control (FTC) problems are studied for the switched system with sensor fault, actuator fault, and stochastic noise. The dynamic FE observers are used to reconstruct the system states and faults at the same time. Differently from the classical observer design method, in the process of observers design, both the output information and its derivative are introduced to improve the estimation performance, especially in the case of the systems subject time‐varying fault. Based on the coordinate transformation, the output derivative is not appeared in the observers, which means that the proposed dynamic observers can be used for the cased that the output derivative is unmeasured. Utilizing the estimate information, the observer‐based FTC scheme is given. For any switching signal, the linear matrix inequality (LMI) conditions are provided, which can ensure that the entire system is mean‐square exponentially stable (MSES). Finally, simulation examples show the effectiveness of the observer and controller.
