Authors: Al Ajmi Mohammed , Mustakim Siti Salina , Roslan Samsilah , Almehrizi Rashid
Published: November 2024

This study evaluates the psychometric properties of the spatial ability test using the three-parameter logistic model within item response theory. The final version of the scale comprised 29 dichotomous items, administered to a sample of 2,694 male and female students from grades 5 and 6 across schools in the Arab Gulf region. The test adhered to the three-parameter model, satisfying the assumptions of unidimensionality and local independence. The item difficulty parameters ranged from -1.541 to 1.735, discrimination parameters spanned from 0.419 to 5.252, and guessing parameters varied between 0.00 and 0.346. With a marginal reliability coefficient of 0.86, the scale demonstrated strong stability. These findings indicate that the test items align with established measurement principles, supporting the spatial ability test as a valid and reliable assessment tool for measuring spatial abilities in the Gulf region. The results have important implications for educational assessment in the Arab Gulf and could guide the development of similar assessments in other educational contexts. Further research is recommended to improve the test’s precision and explore its application in diverse educational settings.

Published: November 2024

The worldwide view of education has experienced a significant shift due to technical improvements and the COVID-19 epidemic. The pandemic’s disruption led to the adoption of contemporary technologies like blended learning and online learning by international educational institutions. Calls for converting educational material to electronic forms have arisen as there is a rising realization that conventional education must change to meet the job market’s needs. The benefits of innovative and traditional education may be combined via blended learning. As a result, the primary goal of this article is to review the research article with a systematic review as an added value. PRISMA is used to guide the review process. However, three databases were used: Scopus, Web of Science, and Google Scholar. According to the articles, this study’s findings investigated (1) existing knowledge gaps of blended learning; and (2) the effectiveness of blended learning within the UAE secondary schools. Nine articles were evaluated within a limited period of 2020 to 2023, two were qualitative research, five were quantitative, and two were mixed research. The findings showed the effectiveness of blended learning in UAE secondary schools; however, it needs more research, practical implementations, and experience to make blended learning successful. In addition, the issues and challenges of some factors that impact the effectiveness of blended learning are also discussed. The results of this study constitute a valuable contribution to the existing body of scholarly knowledge and have practical implications for educational policymakers, administrators, and instructors.
Practice-based research in the Social Sciences & Humanities: A bibliometric analysis
Authors: Lewandowska Kamila
Published: November 2024

Practice-based research (PBR) has emerged as a promising alternative to traditional models of academia–practice collaborations, aiming to integrate scientific inquiry with practical interventions. However, the lack of a comprehensive, cross-disciplinary understanding of PBR has obstructed its recognition and led to inadequate evaluation frameworks. To address this gap, this study conducted a bibliometric analysis across the Social Sciences and Humanities disciplines to explore trends in PBR adoption and publication. Analyzing 3,417 documents from the Web of Science, it examined PBR research trends and utilized bibliometric mapping to identify thematic research clusters and historical evolution patterns. The findings revealed a growing interest in PBR, likely influenced by a focus on societal impact and educational reforms, such as the integration of vocational education into academic structures. It emphasized the need for cross-disciplinary exploration of PBR, shedding light on its diverse approaches and providing a systematic, data-driven perspective beyond theoretical frameworks.

Futural Leadership Theory: Synthesizing a Dynamic Avant-Garde Change Model, in the Age of Artificial General Intelligence (AGI)
Authors: Markham Paul A.
Published: November 2024

As quantum computing fuels the journey toward artificial general intelligence, there is unambiguous evidence that we need to investigate, review, analyze, and adjust previous leadership and change management constructs. For one hundred years, leadership scholars have skillfully documented and debated numerous types of leadership. This paper presents a controversial, timely, and necessary review of the basis of leadership and change management research, recommending a new paradigm. This new era and leadership theory postulates new methods of training leaders to think metacognitively, delivering a more intelligent road forward, in this age of artificial intelligence. Furthermore, the well-worn idiom of “change is the only constant” is now a reality in the 21st Century, driving the author to reexamine the intersection of leadership and change management research. The author presents the landmark futural leadership theory with a uniquely integrated and dynamic avant-garde change model. This seminal leadership and change management research is poised to transform scholarly leadership theory, and impact applied work with leadership practitioners in organizations worldwide, as we move towards artificial general intelligence.
CORRELATION BETWEEN FERRITIN, IL-6 AND IL-1Β
Authors: Flavio Gomes Jardim Filho Marcelo
Published: November 2024

Inflammation plays a central role in the pathogenesis of cardiovascular diseases (CVDs), with the pro-inflammatory cytokines IL-6 and IL-1β exerting direct influence on atherosclerosis progression, endothelial dysfunction, and adverse cardiovascular outcomes. This article reviews the correlations between ferritin, an inflammatory and metabolic biomarker, and the cytokines IL-6 and IL-1β, emphasizing their relevance in chronic inflammatory states and their association with cardiovascular dysfunction. Ferritin, often elevated in response to IL-6 and IL-1β activity, reflects both an attempt by the organism to mitigate oxidative damage and a marker of inflammatory aggravation. Recent studies, including clinical trials with anti-inflammatory agents such as canakinumab, colchicine, and tocilizumab, suggest that targeted inhibition of these inflammatory pathways can significantly improve cardiovascular outcomes. Finally, this review highlights the need for personalized therapeutic strategies, considering patients’ inflammatory profiles and biomarkers, to optimize clinical interventions and improve prognosis in CVDs.
Money and Time in Access to Public Services: How Do Citizens Evaluate Different Forms of Bureaucratic Corruption?
Authors: Carreras Miguel , Vera Sofia , Visconti Giancarlo
Published: November 2024

There is extensive research about how bureaucracies in the developing world depart from the Weberian ideal and the ways in which corruption distorts the provision of public services. However, less is known about how citizens respond to the corruption they encounter in daily life. In this study, we implement a conjoint experiment to investigate how citizens evaluate different forms of corruption in the public sector. We find that they prefer “speed money” corrupt bureaucrats and reject “petty theft” corrupt bureaucrats when seeking a government service. In addition, this preference for “speed money” is not more salient among citizens who perceive the bureaucracy as inefficient. Instead, those who can afford to pay bribes are more accepting of bureaucratic corruption.

Where could surface water be used for Managed Aquifer Recharge (MAR) in the Besòs catchment, considering quantity and quality?
Authors: Scrinzi Luciana , Pérez Sandra , Pujades Estanislao
Published: November 2024

Abstract. Enhancing aquifer recharge could support climate adaptation in the Besòs basin and in the rest of Catalonia (Spain). This study examines how water quality in aquifers and streams varies along the catchment, and changes in surface water quality during wet and dry periods. Data from 2013 to 2023 from 20 river stations and 26 wells were used to map salinity (EC, Na+, Cl−, SO42-) and nutrient parameters (PO43-, NH4+, NO3-, TOC). Results indicate declining water quality downstream, necessitating salinity control during dry periods and ongoing nutrient management even in wet periods to preserve groundwater quality. These findings will inform the development of numerical models to test MAR methods and recharge strategies in the basin.

Published: November 2024

Abstract. Diatoms play a major role in carbon and silicon cycles, and thus diatom-bearing sediments represent an archive of past climatic and environmental settings. In shallow-marine and freshwater environments, the accumulation of diatom frustules forms a sedimentary rock called diatomite. While most global-scale studies of diatom-bearing sediments focus on deep-sea sites, shallow-marine and freshwater diatomites are studied mainly at a regional level. To address this problem, we present a global-scale compilation of diatomite occurrences spanning the Palaeogene (∼66 to ∼23 Ma). This period was characterized by initial extreme warmth, followed by prolonged cooling, disrupted by short-term climatic events called hyperthermals and by a number of palaeoceanographic and palaeogeographic changes. The aim of this compilation is to determine the response of diatom production to Palaeogene environmental fluctuations by examining the influence of climate, tectonic activity, and ocean circulation on diatomite deposition. Although climatic factors appear to have had an indirect impact, our study suggests that palaeogeographic and palaeoceanographic changes were key drivers of diatomite deposition during the Palaeogene, particularly from the Early Eocene Climatic Optimum (∼53 to ∼49 Ma) onwards. In fact, our compilation suggests the absence of diatomite deposition in epicontinental seas between ∼46 and ∼44 Ma, whereas diatomites did not begin to accumulate in open-ocean environments until ∼43.5 Ma. Moreover, we observe that regional climate and volcano-tectonic activity have had an impact on the deposition of freshwater diatomites.
Interdecadal Cycles in Australian Annual Rainfall
Authors: Selkirk Tobias F. , Western Andrew W. , Webb J. Angus
Published: November 2024

Abstract. The extremes of Australian rainfall have profound economic, ecological and societal impacts; however, the current forecast horizon is limited to a few months. This study investigates interdecadal periodicity in annual rainfall records across eastern Australia. Wavelet analysis was conducted on rainfall data from 347 sites covering 130 years (1890–2020). Prominent cycles were extracted from each site and clustered using a Gaussian Mixture Model. This revealed three principal cycles centred around 12.9, 20.4 and 29.1 years that were highly significant over red noise by t-test (p<0.0001). Overall, the three cycles combined had a mean contribution to total rainfall variance (R2) of 13 % across all sites, but this was up to 29 % at individual sites. Both the 12.9-yr and 20.4-yr cycles were detected at over 95 % of sites. The strength of each cycle varied over time and this amplitude modulation of the signal showed a systematic movement across the area investigated. 86 % of extremely wet years fell within the positive phase of the combined reconstruction, with 80 % of extremely dry years falling in the negative phase. These results indicate underlying periodicity in annual rainfall across eastern Australia, with the potential to build this into long-term forecasts. This concept has been suggested in the past, but not rigorously tested. These findings open new paths for research into rainfall patterns in Australia and internationally. They also have broad implications for the management of water resources across all sectors.
Early warnings of the transition to a superrotating atmospheric state
Authors: Williamson Mark S. , Lenton Timothy M.
Published: November 2024

Abstract. Several general circulation models (GCMs) show bifurcations of their atmospheric state under a broad range of warm climates. These include some of the more extreme global warming scenarios. This bifurcation can cause the transition to a superrotating state, a state where its angular momentum exceeds the solid body rotation of the planet. Here we use an idealised GCM to simulate this transition by altering a single non-dimensional control parameter, the thermal Rossby number. For a bifurcation-induced transition there is potential for early warnings, and we look for these here. Typically used early warning indicators, variance and lag-1 autocorrelation, calculated for the mean zonal equatorial wind speed, increase and peak just before the transition. The full autocorrelation function taken at multiple lags is also oscillatory, with a period of 25 d preceding the transition. This oscillatory behaviour is reminiscent of a local supercritical Hopf bifurcation. Motivated by this extra structure, we use a generalised early warning vector technique based on principal oscillation patterns (POPs) to diagnose the dominant spatial modes of the horizontal wind field fluctuations. We find a zonal-wavenumber-0 pattern that we call the “precursor” mode that appears shortly before and disappears soon after the transition. We attribute the increase in the early warning indicators to this spatial precursor mode. This mode is correlated to oscillations in strength of the Hadley cells. Following the transition, an eastward-propagating zonal-wavenumber-1 mode of period ∼4 d dominates the dynamics. This mode appears to be representative of the Kelvin–Rossby instability others have previously identified. Although the control parameter used to simulate the transition is unlikely to be relevant to future climate change, the Kelvin–Rossby transition mechanism may well be relevant, and the simulations reported here do show early warnings and serve as a test bed for whether we can detect this transition before it happens.
On the cause of large daily river flow fluctuations in the Mekong River

Published: November 2024

Abstract. Natural fluctuations in river flow are central to the ecosystem productivity of basins, yet significant alterations in daily flows pose threats to the integrity of the hydrological, ecological, and agricultural systems. In the dammed Lancang–Mekong River (hereafter LMR), the attribution of these large daily flow changes to upstream regions remains mechanistically unexamined, a factor blamed on challenges in estimating the time required for large daily shifts in upstream river flow to impact the downstream stations. Here, we address this with a newly developed subbasin modeling framework that integrates 3D hydrodynamic and response time models, together with a hydrological model with an embedded reservoir module. This integration allows us to estimate the time required between two hydrological stations and to distinguish between the contributions of subbasins and upstream regions to large daily river flow alterations. The findings revealed a power correlation between upstream river discharge and the time required to reach downstream stations. Significant fluctuations (greater than 1 m) in the river's daily flow were evident before the advent of the era of human activities, i.e., before 1992, with around 92 % of these fluctuations occurring during the wet season, particularly in June, July, and August. This pattern persisted throughout subsequent periods, including the growth period (1992–2009) and the mega-dam period (2010 to 2020), with minimal variation in the frequency of events. The Lancang basin contributed approximately 33 %–42 % of these large river fluctuations at the Chiang Saen station. We found that daily-scale water level and runoff might not fully capture dynamic river flow changes, as significant differences were observed between daily and subdaily river flow profiles. Subbasins significantly contributed to mainstream discharge, leading to substantial shifts in mainstream daily river flows. The outcomes and model derived from the subbasin approach have significant potential for managing river fluctuations and broader applicability beyond the specific basin studied.
Correlation between seismic activity and acoustic emission on the basis of in situ monitoring
Authors: Zhu Zhiwen , Jiang Zihan , Accornero Federico , Carpinteri Alberto
Published: November 2024

Abstract. Since April 2023 an in situ experimental campaign has been underway in a granite underground tunnel, which is a dedicated monitoring platform located in Southeast China. Acoustic emission (AE) signals and seismic sequences were recorded simultaneously by installing the AE device together with the seismometer in order to investigate, among other parameters, the b value and the natural-time variance, κ1, of AE time series. In addition, AE and related temporal correlation with incoming seismic events are analysed using an appropriate multi-modal statistical analysis. The results show that AE has a strong correlation with seismic swarms in surrounding areas. The changing trend in AE temporal distribution occurs before that of the earthquake and regularly anticipates a major seismic event by approximately 17 h. The AE bursts indicate that an earthquake is approaching. The dense clusters of AE are closely related to two major earthquakes with Richter magnitudes equal to 3.2 and 2.4. Approaching the earthquake occurrence, the b value shows a downward trend, reaching its minimum value prior to the earthquake, whereas the natural-time variance κ1 rapidly decreases from 0.07 to a minimum value close to zero. Moreover, κ1 occurs earlier than the minimum b value and the AE bursts. Therefore, trends in the b value and the natural-time variance derived from the AE time series can be used as effective earthquake precursors. It is also evident that there is widespread micro-seismic activity in the earthquake preparation zone before the earthquake occurrence. The micro-seismic activity represents the origin of microcracks in the nearby ground surface, resulting in the AE bursts. The results of this paper provide new experimental evidence for the application of fracto-emissions as seismic precursors.
The future of Upernavik Isstrøm through the ISMIP6 framework: sensitivity analysis and Bayesian calibration of ensemble prediction

Published: November 2024

Abstract. This study investigates the uncertain future contribution to sea-level rise in response to global warming of Upernavik Isstrøm, a tidewater glacier in Greenland. We analyse multiple sources of uncertainty, including Shared Socioeconomic Pathways (SSPs), climate models (global and regional), ice–ocean interactions, and ice sheet model (ISM) parameters. We use weighting methods based on spatio-temporal velocity and elevation data to reduce ice flow model uncertainty and evaluate their ability to prevent overconfidence. Our developed initialization method demonstrates the capability of Elmer/Ice to accurately replicate the hindcast mass loss of Upernavik Isstrøm. Future mass loss predictions in 2100 range from a contribution to sea-level rise from 1.5 to 7.2 mm, with an already committed sea-level contribution projection from 0.6 to 1.3 mm. At the end of the century, SSP-related uncertainty constitutes the predominant component of total uncertainty, accounting for 40 %, while uncertainty linked to the ISM represents 15 % of the overall uncertainty. We find that calibration does not reduce uncertainty in the future mass loss between today and 2100 (+2 %) but significantly reduces uncertainty in the hindcast mass loss between 1985 and 2015 (−32 % to −61 % depending on the weighting method). Combining calibration of the ice sheet model with SSP weighting yields uncertainty reductions in future mass loss in 2050 (−1.5 %) and in 2100 (−32 %).

In this context, our existing assessment procedures are unable for developing measuring these above mentioned skills and traits with traditional assessment procedures. In this context, a panel survey study was designed to examine the development of critical and innovative thinking skills through an intervention of authentic assessment tasks using learning management system (LMS). A cohort of MPhil students (N=38) was pretested and went through an intervention of two semesters in which ten different tasks were given to students for developing critical and innovative thinking skills. At the end of course assessment tasks were evaluated against a rubric to find the evidence of critical and innovative thinking skills in completing tasks and a post-test of skills was taken. Internal validity threats were controlled during intervention and reliability of scale was ensured (α=.965). The findings of the study highlighted a significant positive change in the development of students ability to draw conclusions (p= .004), decision making (p=.013) and Implementing new ideas (p=.000). The space for creativity and implementing new ideas in given assignment tasks helped students to enhance critical and innovative thinking skills using learning management system at Allama Iqbal Open University.
Calling Out the Catalogue

The implicit and explicit silencing of Romani and Traveller voices in museum and archive collections, and in the wider narrative of British history, has been increasingly recognised over the last decade (Matthews 2015). In the pursuit of decolonising museums and archives, however, institutional recognition of the significant contributions of Romani and Traveller peoples to the traditional music heritage of the UK and Ireland has largely been absent.
Throughout the 20th century and increasingly since the 1960s, folk song collectors around the British Isles have turned to Romani Gypsies and Travellers in search of traditional songs and music. Hamish Henderson, Ewan MacColl, and Peggy Seeger, amongst others, admired Romani and Traveller singers for preserving what collectors perceived to be native song traditions.  Recordings of Romani Gypsies and Travellers, held in national and regional sound archives, have had a lasting impact on folk repertoires in the UK and Ireland. However, the incorporation of such recordings into specialist collections has tended to erase Romani and Traveller identities. As the cultural and ethnic backgrounds of the singers are rarely acknowledged in the catalogues, and are searchable only with specialist knowledge, their songs are implicitly added to the canon of English, Scottish or Irish folk music. The songs are thus co-opted, not to tell Romani Gypsy and Traveller stories and history, but those of a majority population.
This article addresses specific issues pertaining to an English archive collection held at the Vaughan Williams Memorial Library in Cecil Sharp House, London. Recognising the precariousness of funding that many specialist collections face, we do not simply critique a lack of progress regarding representation. Instead, we outline how Romani and Traveller communities might collaborate with archivists, cultural events organisers, and universities, to connect archival collections with various publics in England today.
Researching a Community in Transition
Authors: Weaver Ieva
Published: November 2024

Since 2004, when Latvia joined the European Union, nearly half of the Latvian Roma have moved abroad, mainly to the UK. This fact has influenced the research on Latvian Roma music. The article self-reflexively explores migration as “losing” a fieldwork community and coping with the loss. A digital action for re-connecting with the Roma community was establishing a Facebook group, “Latvijas romu vēsture un kultūra” (“History and Culture of Latvian Roma”), in the summer of 2019. Initially, the group was defined as a one-way commitment to share historical sources with Roma and people interested in Roma history and culture. Gradually, the group shifted from being primarily a science communication tool to digital participative ethnography. A part of it was exploring Roma’s engagement with music-related content. Another chapter is based on recent fieldwork with Latvian Roma in England. The fieldwork took place among born-again Christian Roma and their established churches and reflected on the traditional Romani values and behavior in this context. The author identifies a triple mobility – physical, social and spiritual – which necessitates a redefinition of the existing framework for researching the Latvian Roma. The article concludes with a reflection on a field-centric, community-centric approach as an interdisciplinary-oriented research practice.
Romani Musical Resistance During Russia's War in Ukraine
Authors: Helbig Adriana
Published: November 2024

Romani activism and political participation in Ukraine grew in earnest when the country declared independence from the Soviet Union in 1991. Western-funded Romani non-governmental organizations guided the early years of political engagement. This first generation of Romani politicians heralded from musical and artistic families, leading to a Romani activism firmly focused on cultural rights. Following Ukraine’s 2014 Euromaidan and Revolution of Dignity, the Romani political narrative shifted from focusing solely on cultural rights to encompassing Romani citizenship rights. Since 2014, many Romani politicians have been elected to local governments. Their leadership has been especially evident since Russian forces invaded Ukraine on February 24, 2022. This article provides an overview of Romani political responses to the war and shares how Roma in Ukraine have mobilized against Russian aggression. Specifically, this article draws on Romani-themed popular Ukrainian-language songs performed during the war. Such performances shared widely on social media have brought Ukrainian Roma into the center of Ukraine’s resistance narrative.

In this article, we investigate Romani musicians and Romani religious musicking, a previously under-researched facet of Roma musicking. We detail the emergence of Romani religious music and its distinctive features, explore its evolution over the past fifty years, and identify the earliest Roma religious musicians in Hungary. Furthermore, this study will highlight the significance of Romani religious music in the process of Romani conversion, the emergence of a Christian Romani collective identity, and the development of Romani relations and inculturation. In addition to historical sources and literature, our study draws on personal field experiences and interviews with Roma believers in Baptist, Catholic, Pentecostal-Charismatic, and Free Christian congregations in Békés, Budapest, Szeged, Szendrőlád, Csatka, and Uszka.

Parents of children with rare diagnoses are often responsible for both providing diagnosistic information to service providers and for coordinating services. This requires diagnostic knowledge, insight into services and belief in yourselfself-confidence. Competence centreers for rare diagnoses provide joint counselling for parents and service providers to ensure good care for the child. The study aimed to describe parents’ health literacy and perceived empowerment before counselling, and their perceived change in this, and in their diagnostic knowledge after after counselling. The participants were 42 parents from 38 families (23.8 % fathers) of children with rare diagnoses (1–16 years). Health literacy and empowerment were measured with the Health Literacy Questionnaire (HLQ) and the Family Empowerment Scale (FES) pre-counsellingbefore and two months post-after counselling. A sub-sample (n = 27) , and 27 parents werewas interviewed two months after counselling interviewed two months post counseling about perceived changes in diagnostic knowledge and health literacy. A content analysis of interview data and statistical analyszes of correlations between with parents’ and children’s age, group differences (gender, educational level and economyfinancial situation), and changes in the outcome measures were conducted. Children’s age and parents’ educational level were related to health literacy, and educational level was also related to perceived empowerment before pre-counselling. Interviews described increased knowledge and health literacy post- counselling. No significant change in health literacy were was found with HLQ. A significant increase in empowerment was found for parents with up to four years of higher education. Parents with initially low health literacy and empowerment showed the greatest increase post- counselling. Joint counselling forof service providers and parents for counseling is an important health psychology work method in health psychology that strengthens parents in their role when as parents to athe child haswith a rare diagnosis.
