The proliferation of big data and analytic workloads has driven the need for cloud compute and cluster-based job processing. With Apache Spark, users can process terabytes of data at ease with hundreds of parallel executors. Providing low latency access to Spark clusters and sessions is a challenging problem due to the large overheads of cluster creation and session startup. In this paper, we introduce Intelligent Pooling, a system for proactively provisioning compute resources to combat the aforementioned overheads. Our system (1) predicts usage patterns using an innovative hybrid Machine Learning (ML) model with low latency and high accuracy; and (2) optimizes the pool size dynamically to meet customer demand while reducing extraneous COGS.
The proposed system auto-tunes its hyper-parameters to balance between performance and operational cost with minimal to no engineering input. Evaluated using large-scale production data, Intelligent Pooling achieves up to 43% reduction in cluster idle time compared to static pooling when targeting 99% pool hit rate. Currently deployed in production, Intelligent Pooling is on track to save tens of million dollars in COGS per year as compared to traditional pre-provisioned pools.

AbstractTo determine the effects of astaxanthin (ASTX) supplementation on the equine gut microbiota during a deconditioning–reconditioning cycle, 12 polo ponies were assigned to a control (CON; n = 6) or supplemented (ASTX; 75 mg ASTX daily orally; n = 6) group. All horses underwent a 16‐week deconditioning period, with no forced exercise, followed by a 16‐week reconditioning program where physical activity gradually increased. Fecal samples were obtained at the beginning of the study (Baseline), after deconditioning (PostDecon), after reconditioning (PostRecon), and 16 weeks after the cessation of ASTX supplementation (Washout). Following DNA extraction from fecal samples, v4 of 16S was amplified and sequenced to determine operational taxonomic unit tables and α‐diversity and β‐diversity indices. The total number of observed species was greater at Baseline than PostDecon, PostRecon, and Washout (p ≤ 0.02). A main effect of ASTX (p = 0.01) and timepoint (p = 0.01) was observed on β‐diversity, yet the variability of timepoint was greater (13%) than ASTX (6%), indicating a greater effect of timepoint than ASTX. Deconditioning and reconditioning periods affected the abundance of the Bacteroidetes and Fibrobacteres phyla. Physical activity and ASTX supplementation affect the equine gut microbiome, yet conditioning status may have a greater impact.
Unconditional Endowment and Acceptance of Taxes: A Lab-in-the-Field Experiment on UBI with Unemployed
Authors: Tena Estrada Blanca , Luong Nhat 
Published: May 2024

Abstract
A universal basic income (UBI) would be a guaranteed income floor for both the employed and the unemployed, from which economic theory predicts a gain in bargaining power and a disincentive to work. For high earners, the increase in taxes necessary to fund this program would decrease their motivation to earn. To assess these aspects, we conducted a lab-in-the-field experiment at a State Employment Service office in Spain. The unemployed participants received either an initial unconditional endowment, framed under the logic of the solidarity condition of UBI (UBI treatment) – to examine the taxes’ effect – or as a participation fee (FEE) or no initial endowment (NONUBI). Subsequently, they faced one default randomized task from a set of four paid real-effort tasks. To study bargaining power, they could change the task up to three times and/or skip all tasks and conclude the experiment. In the FEE treatment, they yielded the highest earnings. While we did not find a statistically significant difference in earnings between the FEE and the NON-UBI treatments, the UBI differed from the NON-UBI and FEE. A likely reason could be a crowding-out of motivation by the pressure to reciprocate without believing in other participants’ deservingness of the UBI. In addition, the results reveal that females change tasks more frequently than males.
One-pot synthesis of a network of Mn2O3–MnO2–poly(m-methylaniline) composite nanorods on a polypyrrole film presents a promising and efficient optoelectronic and solar cell device

Published: May 2024

Abstract
A one-pot synthesis approach was employed to create a composite nanorod structure (Mn2O3–MnO2–poly(m-methylaniline) or Mn2O3–MnO2–PmMA) on a polypyrrole (Ppy) film. Optoelectronic and solar cell thin film devices were constructed using n- and p-type layers of Mn2O3–MnO2–PmMA and Ppy, respectively. The optical characteristics of the n-layer, coupled with the morphological behavior of its nanorods, enhance optical absorbance efficiency, reducing the bandgap value to 2.48 eV. The behavior of the optoelectronic device is chiefly determined by the significantly higher current density (J
ph) value of 0.017 mA/cm2 compared to the dark current density (J
o) value of 0.002 mA/cm2. Additionally, the linear dynamic range is 85 dB, and the noise ratio is 12%. The optimized values for the photosensitivity (R) and detectivity (D) at 340 nm are 0.22 mA W−1 and 0.47 × 10⁸ Jones, respectively. Even at 540 nm, these values decrease to 0.08 and 0.2 × 10⁸ Jones, respectively. For solar cell behavior, the short-circuit current (J
SC) and open-circuit voltage (V
OC) at 540 nm are determined, yielding values of 0.001 mA/cm2 and 0.98 V, respectively. The outstanding performance of this optoelectronic device, coupled with its solar cell behavior, positions the thin film material for a dual role in various industrial applications.
Bilingual education in postcolonial Mozambique as a site for creation of ethical spaces of otherwise
Authors: Chimbutane Feliciano 
Published: May 2024

Abstract
Using a broad decolonial approach and taking the bilingual education field as reference, in this article I analyse the intersection of language ideology, education and social order in Mozambique. More, specifically, I combine transformative notions of “Linguistic Citizenship” and “spaces of otherwise” to uncover “coloniality of language” in education and in other fields, and to understand how spaces of possibility are being created and maintained. The combination of these notions allows us to understand the politics of language in diverse multilingual contexts and how alternative modes of languaging, thinking and being may emerge and endure over time or be silenced. I argue that, in addition to the current “enabling” legislative and policy framework in Mozambique, there is a need to transform institutional structures as well as the positionality of the vulnerable and marginalised citizens, as these are necessary conditions for fostering “diversity of voice” and “mutuality and reciprocity” of engagement across difference. In this regard, I discuss how agency and transformation within bilingual education have the potential to trigger ethical transformations in other societal fields.
Ethical events in the internationalising university: engaging, learning and knowing in spaces of otherwise
Authors: Holmes Luke 
Published: May 2024

Abstract
This paper suggests that a sociolinguistics of potentiality is an “ethical” sociolinguistics that will grapple with the difference of others. Drawing on a linguistic ethnography of Social Sciences classrooms in a Swedish university, it illuminates how students and teachers work to foster improved sociality and mutual responsibility across social and linguistic difference in internationalising university life. The paper develops through a consideration of Levinasian “ethical events”, defined as interactions involving that which is not known, normative or ordinarily visible, but for which all involved are called upon to take responsibility. Analysis of the ethical events involving instances of embodied interdiscursive performance brings to light how late liberal values such as individualism and competition could be disrupted in favour of collaborative and mutually responsible academic and social practice. Yet, as is characteristic of “spaces of otherwise”, the task of shaping such new relations in and around the classroom spaces involved risk and exhaustion. The study concludes by arguing that constructing university spaces as open to different ways of engaging, learning and knowing involves an orientation in response to others’ desire for mutuality and reciprocity.
Towards a sociolinguistics of potentiality: Linguistic citizenship, quasi-events, and contingent becomings in spaces of otherwise
Authors: Kerfoot Caroline , Stroud Christopher 
Published: May 2024

Abstract
In writing of the economies of abandonment of late liberal globalization, Elizabeth Povinelli also points to the potential for SPACES OF OTHERWISE, those spaces of “curiosity and risk, potentiality and exhaustion” which open possibilities for more ethical becoming and the emergence of new forms of sociality and social life (2012. The will to be otherwise/the effort of endurance. South Atlantic Quarterly 111(3). 453–475: 454). This Special Issue aims to contribute to an expanded, southernized sociology of language and sociolinguistics by exploring what role sociolinguistics can play in thinking through and with these spaces. It brings together a set of papers from southern contexts rarely represented in sociolinguistic research (Crimea, Mozambique, Palestine) spaces of grim endurance where suffering is chronic rather than catastrophic, and a study of the metaphorical south in the north, where migration imperatives land people in situations of precarity, in this case, Sweden. An illuminating invited commentary offers a novel perspective on the key theme QUASI-EVENT threading across all the papers. In exploring the construction of spaces of otherwise, authors use the southern concept of Linguistic Citizenship that construes language as a site of political struggle. This framing offers an alternative approach to a politics of language where potentialities for otherwise can be attended to. The papers show how, through acts of Linguistic Citizenship, participants bring potential worlds into existence, however fleetingly. From the chronicling of these ‘quasi-events’ emerges a sociolinguistics of potentiality, one which contributes to an understanding of what enables some emergent forms of life to endure and others not. The sociolinguistics of potentiality is an invitation to listen beyond and within ‘noise’ to those who inhabit discounted bodies and speak unvalued languages, to move beyond ‘community’ and ‘selfhood’ to becoming otherwise with others in projects of world-building, simultaneously prompting research which seeks to be ‘ethically otherwise’.
Generalized energy-conserving dissipative particle dynamics with mass transfer: coupling between energy and mass exchange

Published: May 2024

Abstract
The complete description of energy and material transport within the Generalized energy-conserving dissipative particle dynamics with mass transfer (GenDPDE-M) methodology is presented. In particular, the dynamic coupling between mass and energy is incorporated into the GenDPDE-M, which was previously introduced with dynamically decoupled fluxes (J. Bonet Avalos et al., J. Chem. Theory Comput., 18 (12): 7639–7652, 2022). From a theoretical perspective, we have derived the appropriate Fluctuation-Dissipation theorems along with Onsager’s reciprocal relations, suitable for mesoscale models featuring this coupling. Equilibrium and non-equilibrium simulations are performed to demonstrate the internal thermodynamic consistency of the method, as well as the ability to capture the Ludwig–Soret effect, and tune its strength through the mesoscopic parameters. In view of the completeness of the presented approach, GenDPDE-M is the most general Lagrangian method to deal with complex fluids and systems at the mesoscale, where thermal agitation is relevant.

Published: May 2024

Abstract
This study proposes a hybrid approach combining Energy Detection (ED) and Matched Filter (MF) spectrum sensing techniques to enhance power spectrum density (PSD) in optical Nonorthogonal Multiple Access (NOMA) systems. Optical NOMA has emerged as a key technology for boosting spectral efficiency in optical communication networks. However, optimizing PSD remains a critical challenge due to various factors including signal detection and noise interference. The hybrid ED–MF spectrum sensing method aims to address these challenges by leveraging the strengths of both techniques. Energy Detection (ED) offers simplicity and robustness in detecting primary users, making it suitable for initial spectrum sensing in cognitive radio networks. Matched Filter (MF) spectrum sensing, on the other hand, provides superior signal detection and noise rejection capabilities, particularly in low signal-to-noise ratio (SNR) environments. By integrating these two techniques, we aim to achieve improved sensitivity and accuracy in spectrum sensing, thus enhancing spectral efficiency and system performance in optical NOMA networks. The effectiveness of the proposed hybrid approach is evaluated through theoretical analysis and simulation experiments. Results demonstrate significant enhancements in spectral efficiency and system reliability compared to conventional spectrum sensing methods, highlighting the potential of the hybrid ED–MF approach for enhancing PSD in optical NOMA systems. This research contributes to advancing the design and optimization of optical communication systems for future high-capacity and high-speed data transmission applications. The PSD values −920 are obtained and it confirmed that the proposed algorithm outperforms the standard algorithms.
The role of recoverability in the implementation of non-phonemic glottalization in Hawaiian
Authors: Davidson Lisa , Parker Jones Oiwi 
Published: May 2024

Abstract
Previous research has shown that non-phonemic uses of glottalization are often prosodically determined in a variety of languages such as English, German, Polish, and Spanish. We examine the use of inserted glottalization in Hawaiian, a language that also has a phonemic glottal stop, to determine whether the distribution and realization of non-phonemic glottalization is conditioned by higher prosodic boundaries and/or prosodic prominence as found in other languages. The spontaneous speech data in this study comes from the Hawaiian-language radio program Ka Leo Hawaiʻi, which featured interviews with bilingual Hawaiian–English speakers in the 1970s and 1980s (Kimura, Larry (Producer). 2020. Ka Leo Hawaiʻi [radio program]. Kaniʻāina, the digital repository of Ka Haka ʻUla O Keʻelikōlani, College of Hawaiian Language, University of Hawaiʻi at Hilo. Available at: https://ulukau.org/kaniaina/). Results show that non-phonemic glottalization occurs most often before an unstressed, monophthongal single-vowel grammatical marker (/a e i o/), where it is also longer, as well as before unstressed vowels and between different flanking sounds. Full closures were more likely between identical vowels, but stress does not affect realization. These results are not consistent with the use of glottalization at higher prosodic boundaries or to mark prosodic prominence. Instead, the preponderance of non-phonemic glottalization before single-vowel grammatical markers may be to ensure that these critical markers are recoverable and not perceptually subsumed by the preceding vowel.
Dynamic simulation of non-Newtonian boundary layer flow: An enhanced exponential time integrator approach with spatially and temporally variable heat sources
Authors: Arif Muhammad Shoaib , Abodayeh Kamaleldin , Nawaz Yasir 
Published: May 2024

Abstract
Scientific inquiry into effective numerical methods for modelling complex physical processes has led to the investigation of fluid dynamics, mainly when non-Newtonian properties and complex heat sources are involved. This paper presents an enhanced exponential time integrator approach to dynamically simulate non-Newtonian boundary layer flow with spatially and temporally varying heat sources. We propose an explicit scheme with second-order accuracy in time, demonstrated to be stable through Fourier series analysis, for solving time-dependent partial differential equations (PDEs). Utilizing this scheme, we construct and solve dimensionless PDEs representing the flow of Williamson fluid under the influence of space- and temperature-dependent heat sources. The scheme discretizes the continuity equation of incompressible fluid and Navier–Stokes, energy, and concentration equations using the central difference in space. Our analysis illuminates how factors affect velocity, temperature, and concentration profiles. Specifically, we observe a rise in temperature profile with enhanced coefficients of space and temperature terms in the heat source. Non-Newtonian behaviours and geographical/temporal variations in heat sources are critical factors influencing overall dynamics. The novelty of our work lies in developing an explicit exponential integrator approach, offering stability and second-order accuracy, for solving time-dependent PDEs in non-Newtonian boundary layer flow with variable heat sources. Our results provide valuable quantitative insights for understanding and controlling complex fluid dynamics phenomena. By addressing these challenges, our study advances numerical techniques for modelling real-world systems with implications for various engineering and scientific applications.
Understanding Contemporary Societal Challenges with Philosophy of Trust
Authors: Pedersen Esther Oluffa , Niknam Arman Teymouri 
Published: May 2024

Abstract
We argue that philosophy of trust can be employed to counter the paralysis of action ensuing out of the experience of polycrisis in the current state of international social life. Philosophy of trust can recognize the impact of the polycrisis on contemporary societies all the while that an analysis of trust inevitably takes the concrete life world experiences of humans as a central part of the analysis. Using the philosophy of trust as an analytic tool involves digging into relations of trust and distrust situated in concrete social environments which takes humans’ concrete experiences of trust, distrust, and breaches of trust into account all the while that its theoretical conceptualizations can pay heed to overall societal challenges. As such it provides a means to study our contemporary world of polycrisis without simplifying the social world or succumbing to paralysis. This is shown in short discussions and presentations of the five articles included in the special issue.
Pentekostale Migrationsgemeinden – Religionspädagogische Annäherungen an ein vieldeutiges Handlungsfeld
Authors: van der Hoek Stefan 
Published: May 2024

Zusammenfassung
Dieser Artikel untersucht die religionspädagogischen Potenziale pentekostaler Migrationskirchen im Kontext des evangelischen Religionsunterrichts. Vor dem Hintergrund der schwindenden Bedeutung traditioneller Kirchenformen widmet sich der Beitrag dem anhaltenden Wachstum pentekostaler Migrationsgemeinden in Deutschland. Diese Gemeinden zeichnen sich bisweilen durch ihre lebendige Glaubenspraxis und ihre Fähigkeit aus, Menschen über kulturelle und sprachliche Grenzen hinweg anzuziehen, was nicht selten zu lokalen Spannungen führen kann. Der Artikel beleuchtet die Notwendigkeit, interkulturelle Kompetenzen zu stärken und den Religionsunterricht weiterzuentwickeln, um den Herausforderungen einer pluralistischen Gesellschaft gerecht zu werden. Dabei werden die sozialen, institutionellen und theologischen Dimensionen pentekostaler Migrationskirchen in Deutschland und ihre Auswirkungen auf den Religionsunterricht analysiert. Besondere Aufmerksamkeit gilt der Glossolalie und der Wohlstandstheologie als charakteristische Merkmale pentekostaler Praxis und Glaubensüberzeugung. Der Beitrag argumentiert, dass die Einbeziehung von Migrationsgemeinden in den Religonsunterricht nicht nur zu einem besseren Verständnis religiöser Vielfalt beiträgt, sondern auch zur Bildung interreligiöser Kompetenzen anregen kann. Ziel ist es, einen dialogorientierten und multiperspektivischen Ansatz zu fördern, der Schülerinnen und Schüler dazu befähigt, die komplexe religiöse Landschaft moderner Gesellschaften kritisch zu reflektieren und ein tieferes Verständnis für die Vielfalt des Christentums zu entwickeln.
Es geht nicht immer so weiter

Published: May 2024

Zusammenfassung
Im Kontext gesellschaftlicher Zwänge zu verzweckter Originalität fragt der Beitrag danach, wie innovative Erkenntnis in der Theologie zu denken sei. Als anthropologische Urszene wird zunächst die persönliche Erschließungserfahrung der taubblinden Helen Keller über die Lesbarkeit der Welt geschildert. Darauf bezogen kann ein theologischer Zugang die anthropologische Grundbedürftigkeit zur Intuition näher ausleuchten. Biblische Traditionen werden transparent als kollektive Gegen-Intuitionen eines sprunghaft qualitativ neuen Lebens. Dem entspricht bildungstheoretisch die Anbahnung der (ambivalenten) Fähigkeit, sich faszinieren zu lassen.

Objective. Autism spectrum disorder (ASD) is characterized by developmental disorders, difficulties in social interaction and communication, and restrictive and repetitive patterns of behavior. Despite its high prevalence, few studies have been conducted in rehabilitation settings. This study aimed to describe the characteristics of children with ASD from the Pediatric Rehabilitation Service of the Rebagliati Hospital (SRP-HNERM). Materials and methods. Cross-sectional descriptive study. We reviewed the medical records of children under 14 years of age previously diagnosed with ASD from the SRP-HNERM during 2022. Results. A total of 120 children with ASD were evaluated. The median age was 5 years. Most received regular education, but it was inclusive only for 9.8%. The mean age at diagnosis was 3.83 years. We found that 78.4% had no disability certificate and 77.5% of the participantshad incomplete psychological evaluation. The median time since the last physical, occupational and speechtherapy sessions was 3, 8 and 3.5 months respectively. Conclusion. The mean age at diagnosis of ASD was olderthan three years, and more than 75% of the patients had neither a disability certificate nor a complete psychological evaluation. The median time since the last rehabilitation therapy sessions was three months or more. Our findings highlight the need to improve early diagnosis, inclusive education and evaluation and subsequent certification of disability, as well as to establish timely interventions.
