Fastholder omsorgsarbejde etniske minoritetskvinder i hjemmet? Noget tyder på, at en kommunal ordning, der giver plejekrævende ældre mulighed for selv at udpege en hjælper i hjemmet, bidrager til det. Vi undrer os over, at forskningsprojektet AISHA, der undersøger, hvordan etniske minoritetsfamilier anvender ordningen, ikke stiller og besvarer spørgsmålet. Det er nemlig oplagt, når man ser på, hvem der gør brug af ordningen, og hvordan.

BETWEEN FICTION AND HISTORY: THE NARRATIVES OF MAJAPAHIT IN GIGREY'S NOVEL 'MADA'
Authors: Fitria Ajeng Aisyah , Priyatama Ardian Nugraha
Published: February 2025

The Majapahit Empire has been a source of inspiration for writers of historical fiction, such as Gigrey with his novel Mada. Unfortunately, these historical fictions have the possibility to make readers experience misunderstanding in comprehending history. Therefore, this study aimed to reveal to what extent historical deviation can be considered as creativity and not deviation and whether it can be considered a deviation when the writer develops the history excessively. This study employed a descriptive-qualitative method and used Lindbald's theory of historical fiction for analyzing the data. The result shows that there is a historical narrative that can be categorized as creativity because it is so imaginative and does not trap readers in false history. Meanwhile, one form of creative change in the novel that traps can be seen when Nertaja is told as Tribhuwana Wijayatunggadewi's adopted son. Because of these creative changes, many readers are trapped in a false history as evidenced by the comments on Goodreads. This is exacerbated by promotional narratives about the author's extensive research, making common reader even more trapped in the falsehood.

Published: February 2025

As population increases in urban centers, urban open spaces are gradually diminishing and the quality of existing spaces is deteriorating. Therefore, when designing open spaces in cities facing issues such as population growth, unplanned urbanization, industrialization, and transportation problems, social dimensions should be considered as much as ecological and economic dimensions. This study focuses on the Ganita Coastal Project, one of the identity spaces of the city of Trabzon. The aim is to determine the social performance of urban open space organizations formed after the implementation of the project and to reveal their effects on the sense of community. The research method consists of surveys that include the evaluation of the social interaction performance provided by the place and the assessment of the sense of community. The research results show that the social interaction performance of the place has a positive and significant relationship with the sense of community. This study defines the sub-dimensions of social features by focusing solely on the social characteristics of the place. The social factors affecting the sense of community are identified as the functional, social, and perceptual sub-dimensions, respectively. The success of the social features such as popularity of place, social accessibility, and variety of activities has allowed for the intense use of this space. This research focuses on the social interaction performance but cannot claim to have examined all the features of the place that constitute social interaction. Considering the importance of urban open spaces as a social stage and their significance in forming relationships between people and places as well as among people themselves, the findings of this study are quite important. The results, especially regarding which social features of a place should be taken into account when designing new urban spaces, can be guiding for both designers and managers.

Published: February 2025

El papel de la ética ambiental planetaria resulta esencial en el siglo XXI para preservar la vida y favorecer el bienestar humano a nivel global. La responsabilidad intergeneracional implica respeto a la biodiversidad y mayor equidad en la distribución y aprovechamiento de los recursos naturales. El diseño sustentable propone crear productos funcionales y estéticos integrando principios éticos ambientales. No solo se trata de minimizar el impacto negativo en el medio ambiente, sino además transitar hacia modos de vida más eficientes y solidarios. Los nuevos sistemas de producción, distribución y consumo de bienes y servicios deben garantizar la mitigación del cambio climático y la conservación de la biodiversidad, además de abrazar la responsabilidad social y la convivencia.
La simbiosis entre ética ambiental planetaria y diseño sustentable representa un compromiso ineludible para todas empresas y los profesionales. Metodológicamente se consideran ejemplos como: The Edge en Ámsterdam y Tesla Gigafactories muestran casos concretos de diseño sustentable y ética ambiental a escala mundial.
Son muchos los desafíos éticos y creativos involucrados con la sustentabilidad ambiental, como: la falta de estándares universales, el consumo excesivo y la obsolescencia programada, así como la exigua equidad y justicia social. Las oportunidades para mejorar la integración de la ética ambiental con el diseño sustentable involucran a la educación, colaboración interdisciplinaria y la innovación tecnológica responsable.

Published: February 2025

La imperiosa necesidad de alcanzar los parámetros de sustentabilidad ha sido uno de los desafíos más grandes a los cuales se han tenido que enfrentar las instituciones de país, por la falta de metodología en su aplicación; por lo cual una herramienta virtual aplicada a su dirección resulta de gran utilidad en el proceso. Como objetivo principal se pretende brindar una guía sistematizada que sea capaz de medir los indicadores de los ODS en las acciones rutinarias de la institución, para poder ajustar las acciones encaminadas a alcanzar sus propios estándares. Como parte del funcionamiento se establece un marco logarítmico básico que sea capaz de ligar las acciones generales de la institución con los indicadores de cada uno de los ODS y sirva como ajuste de metas en su diseño e implementación final, de manejo abierto para cualquier área de la institución. Para poder mostrar los alcances en la instauración del proyecto se toma como referencia las instituciones educativas que tienen planes internos que deben ser analizados y rediseñados para ajustar acciones en pro de los indicadores ODS, pero teniendo como base un sistema planificado que contribuya con la guía y evalúe la incidencia de estos. Una herramienta que pueda ser capaz de asimilar y ajustar las acciones cotidianas, lograr el cumplimiento y ajuste de los ODS para comprender y ejecutar los procesos de forma objetiva.

Published: February 2025

El presente trabajo se integra a partir del quehacer del diseño en todas sus disciplinas como la arquitectura, las artes, el diseño gráfico, de modas, industrial, de interiores, de videojuegos, web, móvil, entre otros; surgiendo un interés por el design thinking, el cual, es una metodología que puede ser aplicada a cualquiera de estos campos de estudio, debido a que, al ser flexible e iterativo, implica modificarlo conforme se trabaja en el proceso creativo durante su desarrollo, por consiguiente, los elementos que conforman la sustentabilidad pueden ser añadidos a éste sin perjudicarlo y mejorando sus resultados. Por lo anterior, se considera prudente responder, para efectos de la posible eficacia de la aplicación del modelo ¿cómo se añade integralmente un elemento externo a una metodología ya establecida? Para lograrlo, se observa la metodología del design thinking, analizando cada uno de sus pasos, verificando sus fortalezas y debilidades, al mismo tiempo que se establece dónde pueden añadirse los conceptos del aspecto sustentable, sin denotar que antes no se encontraban allí. Entonces, después de este análisis, se contrasta el modelo original contra el modelo obtenido, dando como resultado el generar una nueva perspectiva de cuál proceso es ahora más conveniente utilizar, destacando virtudes y contrariedades, así como la posible modificación del producto de diseño esperado. Esto debido a que varios profesionales del diseño ya integran estos elementos en sus producciones, sin embargo, muchos otros, aún necesitan verlo expresado para comenzar a adoptarlo, en pro de alargar nuestra estancia en el planeta Tierra.

Situasi Masyarakat global dewasa ini semakin dipenuhi oleh  berbagai permasalahan yang serba  kompleks. Peperangan, fenomena "Double  Effect  of  Modernity",  kemiskinan  hingga masalah kelaparan dunia, bahkan krisis iklim dunia secara signifikan telah semakin mempersulit kondisi global. Situasi ini, mendorong Manusia agar segera membangun kembali kesadaran hidup bersama dalam semangat perdamaian demi kebaikan manusia itu sendiri. Perdamaian menjadi nilai yang sangat penting dalam membangun kehidupan manusia secara global untuk menghindari situasi kompetitif dan apatis antar negara. Untuk menjelajahi pemahaman tentang realitas dan eksistensi di tengah dinamika dunia modern semacam ini, pandangan filsafat metafisika Alfred North Whitehead memberi pedoman yang sangat membantu manusia untuk berintrospeksi diri akan pluralitas eksistensi setiap induvidu. Konsep "Proses dan Realitas" dalam pandangan Whitehead menggambarkan realitas sebagai serangkaian proses yang terus berubah dalam kesatuan metafisis. Pemahaman ini memungkinkan kita untuk melihat perdamaian sebagai hasil dari integrasi manusia dalam satu dunia yang ketergantungan dan keterkaitannya satu sama lain. Selain itu, agama sejatinya memiliki peran penting dalam upaya membentuk perdamaian global dengan menginspirasi nilai-nilai seperti keadilan dan kemanusiaan. Penelitian ini bersifat kualitatif. Dengan menggunakan metode studi pustaka, penulis mengimplementasikan pemikiran Whitehead terhadap situasi konkret masa kin i. Pandangan metafisis Whitehead membuka perspektif tentang perdamaian sebagai faktor penyatuan dunia secara holistic istimewanya sebagai upaya menghadapi tantangan geopolitik dan konflik global. Tujuan penulisan penelitian ini adalah untuk mendorong introspeksi diri masyarakat akan pentingnya kesadaran harmonis kehidupan bersama yang berimplikasi pada semangat perdamaian.

Penelitian ini berangkat dari maraknya fenomena perselingkuhan dalam hubungan monogami yang terjadi di Indonesia. Perselingkuhan sebagai bentuk pengkhianatan terhadap komitmen, tetapi   tetap   dilakukan   oleh   individu   pelaku   tindakan.   Artinya,   perselingkuhan   bukan pengetahuan baru sebagai tindakan buruk, tetapi pelaku perselingkuhan tetap melakukanya. Maka tujuan penelitian ini adalah mendeskripsi penyebab terjadinya perselingkuhan dalam hubungan  monogami (marital  infidelity)  serta  menganalisis pandangan teori  etika  normatif terhadap tindakan perselingkuhan pada hubungan monogami. Metode penelitian adalah penelitian kualitatif deskriptif yang menggunakan data-data kepustakaan. Data dari penelitian ini terkait objek material fenomena perselingkuhan dalam pernikahan dan objek formal yaitu etika seksual. Dalam analisis melibatkan unsur-unsur metodis, yaitu interpretasi, holistika, dekrisipsi, dan refleksi kritis. Hasil dari penelitian ini adalah pertama penyebab terjadinya perselingkuhan dalam hubungan monogami (marital infidelity), dapat dimotivasi adanya hubungan yang tidak optimal dan ditandai dengan kepuasan yang rendah, konflik yang tinggi dan kurangnya komunikasi yang baik. Faktor lainnya karena hasrat seksual, mencari cinta yang bervariasi, ketidakpuasan secara seksual, marah pada pasanganya, menginginkan lebih banyak cinta dan perhatian dari  pada yang  diberikan pasangan, dan  merasa terabaikan.  Kedua, teori  etika normatif deontologi Kant, konsekuensialisme (utilitairianisme, egoisme etis), dan Virtue ethics tidak membenarkan tindakan perselingkuhan.

Published: February 2025

The mover school program, especially the school human resource strengthening program that has been followed by teachers, is expected to have an impact on the growth mindset of teachers. However, in reality, teachers have not yet maximally possessed growth mindset, so it needs to be improved by carrying out an activity that specifically discusses the topic of growth mindset. In addition, the length of service of teachers also has an impact on teacher performance (in this case the growth mindset of teachers). The purpose of this study was to describe the growth mindset profile of teachers of school drivers in Denpasar City in terms of length of service. This type of research is quantitative descriptive research. The research sample was 46 elementary school teachers representing five groups of length of service (<5 years, 5-10 years, 11-15 years, 16-20 years, >20 years). Research data were collected using non-test techniques in the form of questionnaires. The research instrument adopted the mindset quiz instrument by Carol Dweck, which consisted of 20 statements with 4 answer choices. The collected data were analyzed using descriptive statistics. The results of this study found that the growth mindset profile of teachers at mover schools in Denpasar City is generally dominated by a growth mindset with some fixed ideas, and the growth mindset profile of teachers at mover schools in Denpasar City reviewed from the length of service is dominated by a growth mindset with some fixed ideas. The results of this study will have implications for the selection/implementation of teacher quality empowerment programs, especially programs to improve teacher growth mindset.

Published: February 2025

Mathematics learning in elementary schools is intended so that students can master basic Mathematics knowledge and concepts in it and are skilled in applying it to real life. Facts in the field show that many students still have low Mathematics learning outcomes. This study aims to analyze the effect of the problem based learning model on the Mathematics learning outcomes of fifth grade elementary school students. The research design used is Quasi Experimental Research with the type of Non Equivalent Control Group Pre-test Post-test Design. The population in this study was 144 fifth grade elementary school students spread across nine schools. Sampling in this study used the Cluster Random Sampling technique with 16 students as the experimental group and 22 students as the control group. The technique of collecting Mathematics learning outcome data was carried out using a multiple-choice test consisting of 20 questions. Furthermore, the data was analyzed using the t-test. The results obtained were t count = 8.14 and ttable = 1.69. The test criteria showed tcount (8.24) > ttable (0.69) so H1 was accepted and H0 was rejected. This indicates that there is a significant influence of the problem-based learning model on the Mathematics learning outcomes of fifth-grade elementary school students. The latest information in the study has implications for its use as a reference for teachers to improve learning so that students' Mathematics learning outcomes are as expected.
Understanding Bitcoin: Its role in asset price spillovers, responses to monetary policy and impact on global CO2 emissions
Authors:   , Oluwasina Oluwaseun I. D.
Published: February 2025

In a world increasingly driven by technological advancements, cryptocurrencies emerge as a paradox: a beacon of financial innovation with significant environmental costs. This thesis explores Bitcoin's interactions with economic variables and its carbon footprint, aiming to uncover the broader implications of its disruptive presence in both financial markets and ecological sustainability. The first chapter investigates spillover effects between Bitcoin and traditional financial indices and volatility measures. Findings indicate that Bitcoin exhibits significant self-explained variance and minimal spillover from other markets. Despite failing to act as a traditional safe haven during market crises, Bitcoin's relative isolation underscores its unique role due to decentralisation. This contributes to understanding Bitcoin's stability and interconnectedness with broader financial markets, particularly during the COVID-19 pandemic. The second chapter explores the asymmetric impact of U.S. monetary policy on Bitcoin's price. Analysis reveals that Bitcoin prices react differently to monetary policy shocks depending on the interest rate regime. During high interest rates, Bitcoin prices experience substantial and prolonged declines, while the impact is less severe during low interest rates. Highlighting Bitcoin's sensitivity to monetary policy changes. The results suggest why and how cryptocurrencies fit into the asset-based channels of the monetary transmission mechanism. The final chapter assesses the long-run relationship between Bitcoin's carbon emissions and global carbon emissions. Findings establish a positive long-term cointegrating relationship between Bitcoin-related CO2 emissions and global CO2 levels. indicating that while Bitcoin's immediate impact is small, sustained mining could have significant long-term effects.
The Social Construction of Extremism
Authors:   , Berger John M.
Published: February 2025

There is no consensus definition of extremism in academic or policy circles. Most existing definitions classify extremism as a fringe or anti-authority phenomenon that only exists relative to the mainstream of society. This thesis addresses the important gaps that result in the literature. For instance, movements that seize and/or hold power are not considered extremist while in power even if their beliefs and behaviors are substantially unchanged. The relative framework also inhibits the study of how historically mainstream movements (such as White nationalism) are related to contemporary fringe movements with substantially the same beliefs. These questions are vitally important because most extremist movements seek to take control of their host societies. Using grounded theory to analyze case studies across a wide historical span, this thesis argues that defining extremism as “the belief that an in-group’s success or survival can never be separated from the need for hostile action against an out-group” creates a thematically consistent category for comparative and longitudinal study. This thesis concludes that important insights can be generated by comparing diverse ideologies using the definitional framework, especially when comparing movements that are socially dominant to those that are socially marginalized. Across the case studies, extremists are found to grapple with the mechanics of social construction, including strategies to take or claim control of the in-group’s consensus view of reality. Social context also shapes the nature of the hostile actions extremists seek to implement. The thesis concludes with a challenge to the field’s conventional wisdom assertion that extremism presents adherents with a simplified worldview that reduces their cognitive labor.
Modeling the antecedents of integration of ethnomathematical perspectives into geometry teaching among faculty: A logistic regression analysis
Authors: Kyeremeh Patrick , Awuah Francis Kwadwo , Orey Daniel Clark
Published: February 2025

The necessity for establishing links between school mathematics and students' personal lives and cultures, as enshrined in the ethnomathematics program, is being recognized and investigated in different regions across the globe. However, a comprehensive understanding of the antecedents that drive the integration of ethnomathematical perspectives into mathematics teaching among mathematics teachers is still limited. This cross-sectional survey aimed to address this gap by investigating whether the explanatory variables (such as gender, teaching experience, and religion) predict the mathematics teacher educators’ incorporation of the mathematics found outside of school into geometry teaching. We included a sample of 128 mathematics teacher educators in the survey through non-probability sampling. A logistic regression model was employed to analyze the data garnered using a web-based questionnaire. Based on the findings, all three explanatory variables (gender, teaching experience, and religion) did not predict mathematics teacher educators’ incorporation of mathematics found outside of school into geometry teaching. The findings would help key actors of mathematics education to re-examine their beliefs and practices about the incorporation of ethnomathematical perspectives into teaching that builds on students’ socio-cultural experiences. Implications for teaching and future research are reported.
Growth mindset in mathematics: A bibliometric analysis
Authors: Metu Chukwuemeka , Marbán José Maria , Espina Estefanía
Published: February 2025

A growth mindset is the belief that one's intellect and abilities may develop through effort. This mindset suggests that intelligence is not fixed but adaptable. With the continuous growth in literature on the growth mindset in mathematics, there is a need to investigate the current trends from a bibliometric perspective. To meet this need, the leading countries, source citations, author co-citations, and word co-occurrences were examined. A total of 317 articles were retrieved from the Scopus and Web of Science (WoS) databases spanning 2014–2023. The VOSviewer software was used to analyze the collected data. The United States was the leading contributor to growth mindset research, Frontiers in Psychology emerged as the major source of citations, with Dweck being the most cited author. The word co-occurrence map was grouped into different clusters. The Scopus database shows how belief systems shape mindsets and how motivation intersects with clinical and longitudinal investigations. WoS emphasizes the importance of interventions that narrow belief-achievement gaps, as well as the role of technology. These findings offer valuable insights into the expanding body of research on growth mindset in mathematics, paving the way for further research to explore interventions, cultural influences, and long-term effects on student outcomes.

Using a semi-empirical model, the vapor-liquid equilibrium is described in the dimethylzinc-dimethyl telluride system: the activity coefficients of the solution components and the partial-molar heats of mixing at infinite dilution are calculated. The primary data for the application of the semi-empirical model were obtained by us from measuring the temperature dependence of the saturated vapor pressure of highly pure samples of dimethylzinc, dimethyl telluride and their solutions.

The paper is devoted to the study of the sorption properties of residual coal formed after hydrocavitation treatment of brown coal of the Olexandria deposit. The study aims to investigate the possibility of more efficient usage of brown coal processing products that have undergone cavitation treatment. Hydrocavitation of earthy brown coal provides complete and fast extraction of humus acids during extraction with the sodium hydroxide solution. At the same time, the residual coal is pulverized to the size of 10-20 µm. It was shown that the residual carbon has a high sorption capacity (the degree of extraction of methylene blue from the solution is more than 95%).

The exploration of buffer layers in organic bulk heterojunction photovoltaic cells utilizing a blend of MDMO-PPV:PCBM has revealed the effectiveness of both organic solvent-based and electrodeposited polyaniline (PANI) films. Research demonstrates that incorporating polyaniline as a buffer layer significantly enhances the photovoltaic performance parameters over the conventional PEDOT:PSS layers. Notably, the utilization of electrodeposited PANI films has yielded a remarkable increase in power conversion efficiency, achieving an optimum rate of 2.01%. This study underscores the potential of PANI in optimizing the efficiency of organic photovoltaic devices.

Using the oxidation desulfurization method, a plasticizing additive for road bitumen was obtained from high-sulfur brown coal. Taking into account the need to maximize the quantity of the plasticizing additive while maintaining quality, constant conditions of the oxidative desulfurization process were selected and the influence of the main variable technological factors on it was investigated. The sample of a plasticizing additive was obtained in near-optimal conditions of the lignite oxidation desulphurization process. It was established that its addition to bitumen modified with coumarone-indene resin improves the plastic properties of the binder, while the softening temperature practically does not decrease. An increase in the plasticizer dosage increases both penetration and ductility of the resulting mixture. In terms of increasing ductility and penetration, the effectiveness of the plasticizing additive under study is somewhat lower than that of other industrial plasticizers used (e.g., residual extract of selective treatment), and vice versa in terms of reducing the softening point. We found that the resulting plasticizing additive, in contrast to the residual extract of oil fractions selective treatment, slightly improves the adhesive properties of bitumen modified with coumarone-indene resin.

This study examined the suitability of hydrophobic associative tetrapolymers (HATs) for enhanced oil recovery through sandpack flooding. Two novel hydrophobic associative tetrapolymers, herein designated as HAT-1 and HAT-2 were synthesised via free radical polymerisation and the structures were confirmed by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (1H NMR). HAT-1 composed of acrylamide - hydroxyethyl methacrylate - N- vinyl pyrrolidone - N,N-dimethyl acrylamide and HAT-2 consisted of acrylamide - sodium 2-acrylamido-2-methyl propane sulphonate - diallyldimethylammonium chloride - lauryl methacrylate. Comparative tests were carried out under laboratory conditions on the oil displacement efficiencies of the two HAT polymers. The incremental oil recovered using polymer HAT-1 and HAT-2 injection after water flooding were 33.7% and 36.2%, respectively. Combining the oil recovered from water flooding followed by polymer flooding both scenarios, the cumulative recovered using HAT-2, 83.3 % was relatively higher than that of HAT-1, 74.4%. These values are relatively high from the economic perspective. Based on brine viscosity enhancement, mobility ratio reduction and additional oil recovery, HAT-2 polymer exhibited a relatively higher potential to improve oil recovery for reservoirs with characteristics similar to the experimental conditions for this work.
