Published: December 2024

Failure by citizens to accelerate the desired human welfare in their civic engagement is a matter of concern. This article therefore reflects on innovative strategies of civic engagement in National governance of Zambia. A case study design within the domain of qualitative approach was used to generate evidence from 23 participants. The research relied on thematic approach to analyse the data. This research revealed that grounding Civic engagement in the cultural environment of Zambia, enhanced feedback mechanisms, inclusion of Education into platforms of civic engagement, promotion of democratic integrity and inclusion of life skills in the training of clergy men were the main perceived innovative strategies of civic engagement in Nation governance of Zambia. Among others, the research recommends that the Ministry of Home Affairs and Internal security should create an enabling environment for critical watchdog institutions like civic organizations as these help to create a conducive environment where governance can be practiced by good citizens. Equally, the Electoral Commission of Zambia and Non-government organisation must endeavour to provide both internal and external capacity building on civic issues as this is likely to reciprocate positive and informed engagement.

Celulosa bacteriana como agente emulsionante en la producción de una emulsión tipo mayonesa
Authors: Flores Valencia Ember Freddy , Flores Totora Paola Mirella
Published: December 2024

La creciente demanda de productos alimentarios innovadores y sostenibles impulsa la búsqueda de nuevos ingredientes que mantengan la estabilidad y calidad de las emulsiones. Este estudio evaluó el uso de celulosa bacteriana (CB) como emulsionante alternativo en la producción de una emulsión tipo mayonesa, comparándolo con la goma xantana. La CB se obtuvo a partir de un cultivo de SCOBY, y la emulsión tipo mayonesa se formuló con y sin emulsionantes de goma xantana y CB. Para caracterizar su comportamiento físico, se midió la viscosidad de las muestras usando un viscosímetro rotacional, aplicando el modelo de Ley de Potencia, lo cual permitió identificar el comportamiento pseudoplástico de las emulsiones. Sensorialmente, 16 panelistas evaluaron atributos como aspecto, textura, olor y sabor mediante una escala hedónica, y se utilizó ANOVA para determinar la consistencia en las respuestas. Los resultados indicaron que la emulsión con CB mostró una viscosidad inicial más alta y mayor estabilidad bajo esfuerzos de cizallamiento. Sensorialmente, la muestra con CB obtuvo calificaciones superiores en atributos como textura, olor y sabor, con una estabilidad visual sin separación de fases incluso tras 28 días de almacenamiento. Estas propiedades reológicas y sensoriales indican que la CB no solo es un emulsionante efectivo, sino que podría mejorar la percepción del producto final, ofreciendo una alternativa sostenible y funcional.
The Role of Digital Tools in Historical Research: A Study on the Intellectual Network of Gerbert of Aurillac
Authors: Göktepe Bedia , Parlakoğlu Muhammed Nurullah
Published: December 2024

This study employs digital tools to visualize the intellectual network of Pope Sylvester II (Gerbert of Aurillac) and to compare it with established historical narratives. Rather than applying a specific method comprehensively, the study reveals the benefits and limitations of the first use of three different digital tools by comparing them with the literature. In the first chapter, where the text analysis method is applied, Gerbert's life until Reims is discussed to provide the background for this analysis. The application of Voyant Tools has enabled the visualization of words that frequently appear in Gerbert's published letters, thereby providing an overview of his world. In the second part, Map-This, an artificial intelligence (AI) visualization tool, was employed. This tool generates a contextual chart based on index data from Gerbert's letters and visualizes the relationships he established throughout his tenure in Reims. However, including terms in the visualization that are not found in the original source text is a drawback that should be considered. In the final section, a sociogram representing Gerbert's intellectual network was created using Flourish, a web-based visualization tool. The social network analysis method reveals Gerbert's information network through the recipients of his letters requesting books. The fact that his book requests focused on secular rather than theological issues shows that his intellectual environment differed from the typical papal context. This multi-tool and phased approach demonstrate the effectiveness of digital tools in examining historical networks, providing a basis for further studies.

University and the Algorithmic Gaze
Authors: Gourlay Lesley
Published: December 2024

This open access book takes an innovative and critical look at the ways in which digital data and algorithms are changing the face of higher education in multiple ways.It examines their impact at both the macro scale of universities and systems worldwide, but also at the more subtle level of effects on academics and students. In doing so, it focuses on the day-to-day life of the university, examining how the digital is changing the way that we communicate, learn, and create new knowledge.

As well as exploring the role of ‘big data’ and learning analytics, the book also focuses on areas of academic life not normally considered to be part of datafication, such as the physical structures of surveillance on campus and the ways in which systems of ‘quality’ in research can morph into regimes of surveillance and algorithmic discipline. Taking an interdisciplinary perspective, the volume interweaves insights from Surveillance Studies, Science and Technology Studies and Postphenomenology. . Its wide-ranging analysis generates fresh, critical new insights into the nature of communication, semiosis, textual practices, subjectivities and knowledge practices at this dynamic and fast-moving juncture in the history and development of higher education worldwide.

Health Resort in Modern European Literature
Authors: Köhler Astrid , Schmidt Henrike
Published: December 2024

This innovative open access book reappraises the health resort in literature from its rise in the late Enlightenment period to the wellness age of the 21st century. Most of the existing body of academic work on the subject is concerned with either the classic spa novel or sanatorium narratives, and focuses on distinct national literatures, selected canonical texts, and particular themes. Contrary to this conventionThe Health Resort in Modern European Literaturecovers all types of health resort texts and sees them as part of a "transnational resort narrative" that covers the whole of Europe. Its uniquely broad corpus goes beyond the famous English, French, German and Russian novels and includes work in all genres, by female and male authors, from high literature and popular culture, in less studied languages such as Bulgarian, Catalan, Croatian, Polish, Swedish or Ukrainian, right up to the present day.

Drawing on theorists such as Barthes, Deleuze and Foucault, Henrike Schmidt and Astrid Köhler compellingly argue that the literary health resort represents a social microcosm that responds to and reflects historical developments in special ways. Being an ‘other place’ where time and space are configured differently, it has both utopian and dystopian potential, while its intertextual interconnectedness enables it to interrogate assumptions and discourses not just about sickness and health, but also about European society in its different iterations.

Economic Cooperation in the Shadow of Contested Sovereignty
Authors: Wu Chien-Huei , Lin Ching-Fu , Liu Han-Wei
Published: December 2024

This open access book is the first of its kind to address a question of both theoretical and practical significance: how do countries or entities approach economic cooperation in the face of vexing political concerns and overlapping sovereignty claims?

Built upon three contemporary case studies on North-South Korea, China-Taiwan, and North-South Cyprus – representative pairs of ‘divided nations’, broadly defined – the book explores from both an empirical and a conceptual perspective the underlying factors, approaches and patterns that influence the economic relationship between the two sides.

The book examines complex dynamics and identifies critical factors across the case studies, making a timely contribution to debates surrounding sovereignty, democracy and legitimacy in the context of international economic laws given the shifting geopolitical landscape. It further informs countries that do not share the same features of divided nations but nonetheless experience diplomatic crises or military conflicts, which render their economic cooperation sensitive and strenuous.

This book is a must-read for researchers, trade lawyers, and students in international law and international relations. It also serves as a valuable asset for negotiators, diplomats and policymakers, providing crucial insights for making decisions that can either escalate or de-escalate geopolitical conflicts.

The Best Interest of Restorative Justice in the Jordanian Juvenile Law
Authors: Rababah Asmaa
Published: December 2024

The principle of prioritizing the best interests of juveniles within restorative justice is crucial for their care, rehabilitation, and protection at both family and societal levels. This study examines how the Jordanian Juvenile Law No. 32 of 2014 addresses this principle. Using a descriptive analytical approach, the study explores the nature and characteristics of the best interests of restorative justice, how it is embedded within the law, and the mechanisms for its implementation.
The findings indicate that the best interests of restorative justice are recognized as both a fundamental right and a guiding legal principle in the Jordanian Juvenile Law. This principle informs all judicial procedures and stages of legal proceedings involving juveniles, ensuring that their well-being is prioritized in all actions taken by the relevant authorities. By focusing on protection, rehabilitation, and reintegration, the law favors a reformative approach over traditional punitive measures, offering a framework that benefits both juveniles and society at large.
The study recommends the inclusion of detailed legal provisions to support the application of restorative justice within the Juvenile Law. Additionally, it highlights the importance of codifying specialized programs and activities specific to juvenile justice and enhancing collaboration in developing restorative justice programs. Further research is encouraged to evaluate the effectiveness of these practices and to identify areas for improvement within the juvenile justice system.

Published: December 2024

Indonesia as a country with a tropical climate, is famous for its natural wealth and has various kinds of flora and fauna that can be found and utilized. Several herbal products have antioxidant and antibacterial capabilities, one of which is propolis. Bee propolis is a functional food because of its nutrition and contains high levels of bioactive components that help protect health. Raw propolis from farmers needs to be purified before human consumption because raw propolis still contains beeswax, resin, and other impurities. The method used is shaking ultrasound-assisted extraction (SUAE), which produces perfect extraction, higher yield and active content, and a shorter time. The purpose of this research is analyzed optimum conditions for extracted Tetrigona apicalis propolis using the SUAE method in ethanol solvent. The propolis extraction process is that raw propolis is size reduced, then solvent is added and macerated using shaker. Next, the extract is processed with a sonicator, and the extract is filtered. The solvent used is 70% ethanol, and the results of the propolis extract are processed using Response Surface Methodology (RSM). The parameters that were optimized were variations in stirring time of 1-24 hours and ultrasonic process time of 1-20 minutes. The best conditions in the propolis extraction process from the yield response shown were a stirring time of 28.76 minutes and an ultrasonic process time of 23.94 minutes with a yield of 8.735%. Based on statistical analysis using software, stirring time and ultrasonic processing time are factors that have a significant influence on the yield of propolis extract produced. The model used is a quadratic model with R2 0.9452. The yield value of the propolis extract predicted by the software is close to the percent yield value obtained based on experiments carried out with an error value of less than 5%.

Resignificando las vulnerabilidades de la escritura académica en mujeres
Authors: De la Cerda Cecilia , Gutiérrez Valdés Yanina , Romero Lizama Pamela , Verdejo Tabisa , Carrasco-Aguilar Claudia
Published: December 2024

Este estudio revisa cómo las académicas enfrentan los efectos del capitalismo académico y las estructuras patriarcales, que les imponen presiones de productividad y competitividad, conduciendo a silenciamientos y autocensuras. El objetivo es explorar las experiencias narradas de mujeres académicas en torno a una escritura académica que se da en un contexto de altas presiones y capitalismo académico. La investigación sigue una metodología cualitativa basada en memory work, analizando experiencias personales y colectivas de cinco académicas en una universidad pública chilena. Se usó el kintsugi como metáfora para resignificar “fracturas” en narrativas, integrando vulnerabilidades y fortaleza. Los resultados se organizan en dos fases. La primera presenta fragmentos de experiencias de silenciamiento y autocensura. La segunda fase muestra una narrativa integrada que resignifica estos momentos como una red de apoyo mutuo y resistencia frente a las estructuras de poder en la academia. Las académicas participantes transforman sus experiencias de exclusión en conocimiento colectivo, revelando cómo las estructuras patriarcales y neoliberales imponen barreras, pero también destacando la capacidad de generar resistencia y apoyo. Este trabajo contribuye a visibilizar la escritura feminista y situada como una forma de resistencia frente a las normativas hegemónicas de la academia.
Proceso de desnazificación en Málaga (1945-1948)
Authors: Prieto Borrego Lucía
Published: December 2024

La derrota alemana en la Segunda Guerra Mundial supuso por parte del Consejo de Control Aliado la implantación de un programa diseñado para impedir el renacimiento de la capacidad bélica alemana y financiar la reconstrucción posbélica. España, pese a su inicial posición a favor del Eje, formó parte de ese programa comprometiéndose a colaborar en el bloqueo de bienes y activos alemanes y a repatriar a los ciudadanos considerados espías o colaboradores del Reich. Este artículo es una aproximación al desarrollo de ese proceso en la provincia de Málaga. Se pone de relieve el papel desempeñado por el gobernador civil a partir del análisis de fuentes conservadas en el Archivo Histórico Provincial de Málaga: ordenes de la Dirección General de Seguridad de búsqueda y detención de ciudadanos alemanes, y listados nominales de quienes debían ser repatriados al territorio alemán e informes policiales.
¿El principio del fin del colonialismo israelí?
Authors: Ramos Tolosa Jorge
Published: December 2024

Desde el pueblo palestino y numerosos ámbitos del Sur Global hasta la propia prensa israelí e intelectuales judíos israelíes críticos, cada vez son más los argumentos y los datos que indican que el proyecto sionista-israelí es más insostenible que nunca. En medio del horror del genocidio de Gaza, quizá haya esperanza a medio-largo plazo. Una esperanza de que entre el río y el mar no haya apartheid ni genocidio y de que todas las personas -sean judías, cristianas, musulmanas o de ninguna religión- tengan los mismos derechos. Y eso implica el fin del régimen colonial israelí y del sionismo que lo creó y lo mantiene, es decir, la descolonización de Palestina.

Abstract. Wind turbines generate significant seismic noise and interfere with sensitive instruments, such as permanent and temporary seismic sensors installed nearby, hampering their detection capabilities. This study investigates the seismic noise emission from one of Italy’s largest wind farms, consisting of 69 turbines (2 MW each), located in northeastern Sardinia. Characterizing the noise emission from this wind farm is of particular importance due to its proximity to the Italian candidate site for hosting the Einstein Telescope, the third-generation observatory for gravitational waves. We run a passive seismic experiment (WINES, 'Wind turbIne Noise assEsSment in the Italian site candidate for Einstein Telescope') using a linear array of nine broadband stations, installed at increasing distances from the wind farm. Spectral analysis, based on the retrieval of spectrograms and power spectral densities at all stations, shows a significant increase in noise amplitude when the wind farm is in operation. The reconstruction of noise polarization points out that the noise wavefield originates from a direction consistent with the wind farm’s location. We recognize four dominant fixed spectral peaks at 3.4, 5.0, 6.8, and 9.5 Hz, corresponding to the modes of vibration of the wind turbine towers. While decreasing in amplitude with distance, the 3.4 Hz peak remains detectable up to 13 km from the nearest turbine. Assuming an amplitude decay model of the form r -α, where r is the distance, we estimate a damping factor of α∼2, that remains rather constant for each of the four main peaks, an observation that we relate to the good geomechanical characteristics of the local terrain, consisting of granitoid rocks. To better evaluate the possible impact of the wind farm noise emission on the Einstein Telescope, we also analyze the seismic data from two permanent stations bordering the ET candidate site area, each equipped with both a surface and borehole sensor at approximately 250 m depth. Power spectral density analysis for the surface and borehole sensors exhibits similar results and very low noise levels. When the wind farm operates at full capacity, the borehole sensors remain unaffected by the emitted seismic noise, highlighting the significant noise suppression at depth. However, small residual spectral peaks at 3.4 Hz and between 4–6 Hz remain detectable.

Abstract. Relict low-relief surfaces, formed during tectonically quiescent periods, are prevalent within the active mountain ranges of Central Asia, but the timing and processes of their formation within the Mesozoic-Cenozoic tectonic context remain poorly understood. In the Harlik Mountains of the easternmost Tianshan, extensive low-relief surfaces are preserved. Terrain analysis and structural interpretations based on DEM data reveal that these surfaces are segmented by WNW-ESE striking faults, which experienced an initial phase of right-lateral transtensional movement followed by left-lateral strike-slip reactivation. Apatite fission-track (AFT) thermochronology of samples from both relict surfaces and fault zones yields AFT ages ranging from ~110 to ~100 Ma for the relict surfaces, while samples from fault zones record ages of 90–70 Ma. Thermal modeling of these samples indicates a period of moderate cooling in the mid-late Early Cretaceous, followed by a prolonged slow cooling phase for the relict surfaces. In contrast, fault zones show rapid cooling during the 90–70 Ma interval. Integrating these data with previous findings, we suggest that the mid-late Early Cretaceous cooling event corresponds to extensional collapse following the Mongol-Okhotsk orogeny. This period of cooling, enhanced by humid climate conditions, likely promoted erosion and relief reduction, fostering the development of low-relief surfaces. Subsequently, the region experienced right-lateral transtensional faulting at 90–70 Ma, linked to continued extensional tectonics from the orogenic collapse. Late-Cretaceous faulting segmented the area without generating significant topographic contrasts across the relict surfaces. During the Oligocene (~30 Ma), far-field tectonic effects from the India-Eurasia collision initiated a new uplift phase that reactivated boundary and internal faults in a left-lateral sense. This phase marked the end of relief reduction, as surrounding basins began receiving sediments, and resulted in the uplift, dissection, and tilting of low-relief surfaces, ultimately contributing to the formation of the modern Eastern Tianshan Mountains.

Abstract. Temperate semi-natural grassland plant communities are expected to shift under global change, mainly due to land use and climate change. However, the interaction of different drivers on diversity and the influence of diversity on the provision of ecosystem services are not fully understood. To synthesise the knowledge on grassland dynamics and to be able to predict community shifts under different land use and climate change scenarios, we developed the GrasslandTraitSim.jl model. In contrast to previously published grassland models, we link morphological plant traits to species-specific processes via transfer functions, thus avoiding a large number of species-specific parameters that are difficult to measure and calibrate. This allows any number of species to be simulated based on a list of commonly measured traits: specific leaf area, maximum height, leaf nitrogen per leaf mass, leaf biomass per plant biomass, above-ground biomass per plant biomass, root surface area per below-ground biomass, and arbuscular mycorrhizal colonisation rate. For each species, the dynamics of the above- and below-ground biomass and its height are simulated with a daily time step. While the soil water content is simulated dynamically, the nutrient dynamics are kept simple, assuming that the nutrient availability depends on total soil nitrogen and the total plant biomass. We present a model description, which is complemented by online documentation with tutorials, flowcharts, and interactive graphics, and calibrate the model to grassland sites with different number of mowing events and grazing intensity in central Germany. Furthermore, we show how the model can be used to conduct simulation experiments to analyse shifts in plant community composition under different land use intensities. We believe that the GrasslandTraitSim.jl model is a useful tool for predicting plant biomass production and plant functional composition of temperate grasslands in response to management under climate change.

Abstract. Peatlands play an important role in the global CH4 cycle and models are key tools to assess global change effects on CH4 processes. It remains unclear how well our existing wetland modelling frameworks are suited to peatland questions. Therefore, we reviewed 16 peatland or wetland models operating at different spatial (seconds-to-decadal) and temporal (soil core-to-global) scales, having different spin-up periods for carbon pool stabilization and various CH4 production, oxidation and transport processes. Through a literature review, model specific advantages and limitations, common and specific driving inputs of all models and critical inputs of individual models impacting CH4 plant-mediated transport, diffusion and ebullition were summarized. The 16 reviewed models were qualitatively ranked 0 to 4 (none-to-full process representations) with respect to CH4 production, oxidation and transport. The most common temporal and spatial scale for 14 models was daily time-step and field scale respectively, while the spin-up stabilization periods of different carbon pools (peat, litter, roots, exudates, microbial, humus, slow, fast) of all models ranged 7 to 90102 years. With regards to CH4 production and oxidation, 50 % of reviewed models (Ecosys, CLM-Microbe, ELM-Spruce, Peatland-VU, Wetland-DNDC, TRIPLEX-GHG, TEM, CLM4Me) exhibited full to adequate process representation. Meanwhile 44, 44 and 25 % models exhibited full to adequate process representation for plant mediated transport, diffusion and ebullition respectively. This meant there is ample scope to improve ebullition processes in the remaining 75 % models. We conclude that existing models are adequate for site-level CH4 flux assessments but may lack a predictive understanding of CH4 production pathways.

Abstract. The chemical interaction between nitrogen oxides (NOx = NO + NO2) and α-pinene plays a critical role in air quality and climate. However, uncertainties remain regarding their coupling in NOx loss, renoxification, and oxidation chemistry. To address these gaps, we conducted controlled chamber experiments, analyzing nitric acid (HNO3), NO2, and particulate nitrate (pNO3) for their oxygen and nitrogen stable isotope variations (Δ17O, δ18O, and δ15N). A strong linear relationship between δ18O and Δ17O across experiments revealed contributions of oxygen from ozone (O3) and atmospheric oxygen (O2) in forming reactive radicals. The δ15N values followed the order δ15N(pNO3) < NO2 < HNO3, reflecting isotope fractionation during NOx oxidation. A new chemical mechanism accurately predicted aerosol precursor decay and simulated Δ17O and δ15N values. Simulations showed NOx photochemical cycling and pNO3 formation, primarily from organic nitrate, with Δ17O(NO2) simulations achieving a root mean square error (RMSE) of 1.7 ‰. Improved δ15N(NO2) and pNO3 simulations used a nitrogen isotope fractionation factor (15α) of 0.997 for NO2 + OH reactions. However, modeling Δ17O and δ15N of HNO3 proved challenging, likely due to sampling artifacts. This study provides insights into Δ17O transfer dynamics, nitrogen isotope fractionation, and the role of NOx-BVOC chemistry in air quality, highlighting the potential of Δ17O and δ15N as tools for evaluating complex atmospheric processes.

Published: December 2024

Abstract. Luminescence dating plays a pivotal role in Quaternary science, yet ongoing methodological challenges persist in refining the temporal range, accuracy, and precision of luminescence methods. Our contribution revisits zircons as potential alternative dosimeters to quartz, feldspar, or calcite for routine dating applications. The essential advantage of zircons over other minerals is the time-invariant and high internal dose rate due to high radionuclide contents, dominating over the external contribution, which is more challenging to assess. Reported drawbacks are low zircon abundance, laborious sample preparation, signal instabilities, unknown optical signal resetting rates, and low signal intensities. Our present study uses modern luminescence detection equipment and analytical methods to investigate mineral separation, mineral characteristics, bleachability, signal spectra and intensities, and the potential to auto-regenerate signals. We present results for two zircon samples that are different in provenance, trace element composition, and luminescence characteristics, each of them containing a couple of hundred grains. Optically stimulated luminescence (OSL) signal resetting rates of zircon in response to simulated sunlight exposure are orders of magnitudes faster than for feldspar and slightly slower than for quartz. The recorded thermoluminescence (TL) spectra confirm previously published results with luminescence emissions in the UV/violet and red wavelength range, supplemented by narrowband emissions associated with rare earth element (REE) dopants. Storage experiments of single zircon grains for auto-regenerated measurements over 1.5 years yielded very low OSL signals. At the same time, after only 3 weeks, we measured acceptable TL signal intensities at the cost of lower bleaching rates. To date, the auto-regeneration approach seems to be a promising and accurate approach to dating zircon light exposure events, especially when combining the natural OSL with auto-regenerated TL. However, further studies are required to optimise signal intensities and establish zircons as viable targets for routine dating applications.
Improving the efficiency of visual navigation of an unmanned aerial vehicle by choosing the most informative route

Published: December 2024

Abstract. The problem of estimating the coordinates of unmanned aerial vehicles (UAVs) using visual navigation in the absence of satellite navigation signals is considered. The UAV has a camera pointing towards the underlying surface to adjust its position using correlation algorithms. It is assumed that the UAV can choose one of several alternative route options as part of the implementation of the target task. The aim of the study is to increase the effectiveness of visual navigation by choosing a route with maximum information content. When assessing the information content, it is proposed to take into account the size and shape of the correction areas that can be observed during flight along the appropriate routes, based on the predicted density of the distribution of errors in measuring the coordinates of the UAV. During the flight, this estimate can be updated at any time when new information is received. An adaptation of the algorithm for calculating information content for the task under consideration is proposed. As an example, the flight of a UAV with a known model accumulation of an error in determining its coordinates, loaded with a table of landmarks and a correction system is considered. Model calculations show that the proposed approach can significantly increase the probability of correctly estimating the coordinates of the UAV compared to a random choice of route. It should be noted that the estimated informative value of the routes is the average predicted value. Specific implementations can produce results that differ significantly from the calculated averages, however, the proposed algorithm allows to adapt the assessment of informativeness using new information.
Survivor Perspectives on Institutional Use of Child Sexual Abuse Material

This literature review draws together literature describing how child sexual abuse material (CSAM) is currently used in institutional contexts – by police, courts, academic and policy researchers and private sector entities. In doing so, it reveals that there has historically been scant engagement with victims and survivors about such uses, and little research into the impacts of reuse for individuals who are depicted in CSAM. Despite the specificities of CSAM experience (as described by victims and survivors), and the recognised value of lived experience perspectives, inclusion of CSAM victim and survivor perspectives in research design and policies governing institutional reuse of this material is still a rarity. We hypothesise that better outcomes can be achieved for children and adults who experience victimisation through CSAM if these perspectives are prioritised in ways that are supported by human-centred and trauma-informed research and practice.
