Why school context matters in refugee education
Authors: Baak Melanie , McDonald Sarah , Johnson Bruce , Sullivan Anna 
Published: March 2023

AbstractEducation plays an important role in the successful settlement and life outcomes of young people from refugee backgrounds. Because of this, research into young people from refugee backgrounds in education systems tends to focus on examples of “good practice” in terms of how these young people experience education. Yet, examples of good practice commonly fail to take into account that schools are engaging in particular practices from very different contexts. This article contributes to the study of refugee education by drawing attention to the role that school contexts play in how different schools enact “good practice”. It presents data from a large multi-stage study which explored how the schooling experiences of students from refugee backgrounds are shaped by educational policies and school practices. By outlining case studies of seven schools, it highlights the impact of differing school contexts on how schools respond to the needs of students from refugee backgrounds. In this way, this article highlights that the notion of “good practice” within refugee-background education is always nuanced and contextual.
Einstein Completeness as Categoricity
Authors: Toader Iulian D. 
Published: March 2023

AbstractThis paper provides an algebraic reconstruction of Einstein’s own argument for the incompleteness of quantum mechanics—the one that he thought did not make it into the EPR paper—in order to clarify the assumptions that underlie an understanding of Einstein completeness as categoricity, the sense in which it is a type of descriptive completeness, and some of the various ways in which it has been more often misconstrued.
Analytical Solutions for Gravitational Potential up to Its Third-order Derivatives of a Tesseroid, Spherical Zonal Band, and Spherical Shell
Authors: Deng Xiao-Le , Sneeuw Nico 
Published: March 2023

AbstractThe spherical shell and spherical zonal band are two elemental geometries that are often used as benchmarks for gravity field modeling. When applying the spherical shell and spherical zonal band discretized into tesseroids, the errors may be reduced or cancelled for the superposition of the tesseroids due to the spherical symmetry of the spherical shell and spherical zonal band. In previous studies, this superposition error elimination effect (SEEE) of the spherical shell and spherical zonal band has not been taken seriously, and it needs to be investigated carefully. In this contribution, the analytical formulas of the signal of derivatives of the gravitational potential up to third order (e.g., V, $$V_{z}$$

) of a tesseroid are derived when the computation point is situated on the polar axis. In comparison with prior research, simpler analytical expressions of the gravitational effects of a spherical zonal band are derived from these novel expressions of a tesseroid. In the numerical experiments, the relative errors of the gravitational effects of the individual tesseroid are compared to those of the spherical zonal band and spherical shell not only with different 3D Gauss–Legendre quadrature orders ranging from (1,1,1) to (7,7,7) but also with different grid sizes (i.e., $$5^{\circ }\times 5^{\circ }$$

In summary, numerical experiments demonstrate the existence of the SEEE of a spherical zonal band and a spherical shell, and the analytical solutions for a tesseroid can benefit the investigation of the SEEE. The single tesseroid benchmark can be proposed in comparison to the spherical shell and spherical zonal band benchmarks in gravity field modeling based on these new analytical formulas of a tesseroid.
The chaperone system in cancer therapies: Hsp90
Authors: Basset Charbel A. , Conway de Macario Everly , Leone Lavinia Giovanna , Macario Alberto J.L. , Leone Angelo 
Published: March 2023

AbstractThe chaperone system (CS) of an organism is composed of molecular chaperones, chaperone co-factors, co-chaperones, and chaperone receptors and interactors. It is present throughout the body but with distinctive features for each cell and tissue type. Previous studies pertaining to the CS of the salivary glands have determined the quantitative and distribution patterns for several members, the chaperones, in normal and diseased glands, focusing on tumors. Chaperones are cytoprotective, but can also be etiopathogenic agents causing diseases, the chaperonopathies. Some chaperones such as Hsp90 potentiate tumor growth, proliferation, and metastasization. Quantitative data available on this chaperone in salivary gland tissue with inflammation, and benign and malignant tumors suggest that assessing tissue Hsp90 levels and distribution patterns is useful for differential diagnosis-prognostication, and patient follow up. This, in turn, will reveal clues for developing specific treatment centered on the chaperone, for instance by inhibiting its pro-carcinogenic functions (negative chaperonotherapy). Here, we review data on the carcinogenic mechanisms of Hsp90 and their inhibitors. Hsp90 is the master regulator of the PI3K-Akt-NF-kB axis that promotes tumor cell proliferation and metastasization. We discuss pathways and interactions involving these molecular complexes in tumorigenesis and review Hsp90 inhibitors that have been tested in search of an efficacious anti-cancer agent. This targeted therapy deserves extensive investigation in view of its theoretical potential and some positive practical results and considering the need of novel treatments for tumors of the salivary glands as well as other tissues.
A diatom-inferred water-depth transfer function from a single lake in the northern California Coast Range

Published: March 2023

AbstractThis study examines the relationship between water depth and diatom assemblages from lake-sediment-surface samples at Kelly Lake, California. A total of 40 surface-sediment samples (integrated upper 5 cm) were taken at various depths within the small (~ 3.74 ha) 5.7 m-deep lake. Secchi depths, water temperature, pH, salinity, conductivity, and total dissolved solids were also measured. Some diatom species showed distinct association with depth (e.g., Fragilaria crotonensis, Nitzschia semirobusta). The relationship between the complete diatom assemblages and water depth was analyzed and assessed by depth-cluster analysis, a one-way analysis of similarity, principal components analysis and canonical correspondence analysis. Statistically significant differences were found between the assemblages associated with shallow depth (0–1.25 m), mid-depth (1.25–3.75 m), and deep-water (3.75–5.2 m) locations. The relationship between diatom assemblages and lake depth allowed two transfer models to be developed using the Modern Analogue Technique and Weighted Averaging Partial Least Squares. These models were compared and assessed by residual scatter plots. The results indicate that diatom-inferred transfer models based on surface-sediment samples from a single, relatively small and shallow lake can be a useful tool for studying past hydroclimatic variability (e.g., lake depth) from similar lakes in California and other regions where the large number of lakes required for traditional transfer-function development may not exist.
Government R&D and green technology spillovers: the Chernobyl disaster as a natural experiment
Authors: Orsatti Gianluca 
Published: March 2023

AbstractUsing data on green patents filed at the European Patent Office from 1980 to 1984, this paper investigates the effect of increasing government R&D budget on green technology spillovers. Spillovers are measured with patent forward citations over the period 1981–1988. The level of government R&D budget is instrumented leveraging the unexpected occurrence of the Chernobyl nuclear accident—that exogenously pushed governments to reduce their energy-related R&D budgets—in a difference in differences setting. 2SLS results show that a 10% increase in government R&D increases by some 0.7% the number of citations received by green patents. Although positive and significant, the small magnitude of the estimated elasticity suggests that government R&D takes time to let innovation spillovers from green technologies to materialize with some relevance. Interestingly, increasing government R&D expenditures fosters green technology spillovers across traditional (non-green) fields and enlarges the technological breadth of inventions citing green patents. Overall, I conclude that government R&D fosters green knowledge spillovers, accelerates hybridization processes and favors technological diversification around green technologies. However, these positive effects seem to materialize at a slow pace.
Deep learning’s shallow gains: a comparative evaluation of algorithms for automatic music generation
Authors: Yin Zongyu , Reuben Federico , Stepney Susan , Collins Tom 
Published: March 2023

AbstractDeep learning methods are recognised as state-of-the-art for many applications of machine learning. Recently, deep learning methods have emerged as a solution to the task of automatic music generation (AMG) using symbolic tokens in a target style, but their superiority over non-deep learning methods has not been demonstrated. Here, we conduct a listening study to comparatively evaluate several music generation systems along six musical dimensions: stylistic success, aesthetic pleasure, repetition or self-reference, melody, harmony, and rhythm. A range of models, both deep learning algorithms and other methods, are used to generate 30-s excerpts in the style of Classical string quartets and classical piano improvisations. Fifty participants with relatively high musical knowledge rate unlabelled samples of computer-generated and human-composed excerpts for the six musical dimensions. We use non-parametric Bayesian hypothesis testing to interpret the results, allowing the possibility of finding meaningfulnon-differences between systems’ performance. We find that the strongest deep learning method, a reimplemented version of Music Transformer, has equivalent performance to a non-deep learning method, MAIA Markov, demonstrating that to date, deep learning does not outperform other methods for AMG. We also find there still remains a significant gap between any algorithmic method and human-composed excerpts.

Tools and peripersonal space: an enactive account of bodily space
Authors: Sykes John J. 
Published: March 2023

AbstractPeripersonal space (PPS) is frequently defined as a plastic, pragmatic and goal-directed multisensory buffer that connects the brain-body with its immediate environment. While such characterisations indicate that peripersonal spatiality is profoundly embodied and enactive, comparatively few attempts have aimed to systematically synthesise PPS literature with compatible phenomenological accounts of lived space provided by Heidegger and Merleau-Ponty. Moreover, in traditional cognitive neuroscience, neurophysiological activity is thought to map onto discrete ‘cognitive correlates’. In contemporary 4E approaches to cognition, however, phenomenology-derived notions such as ‘pre-reflective cognition’ and ‘motor-intentionality’ frequently appear, yet their neural correlates may be comparatively difficult to pin down. Pre-reflectively, agents seemingly do not thematise spatial properties as operationalised in key experimental paradigms (e.g., spatial rotation tasks) but are instead inherently spatially embedded within the world. To refine this distinction, I survey how tools co-determine this distinctly spatial ‘world-embeddedness’ using a neurophenomenological methodology (Varela, Journal of Consciousness Studies, 3(4), 330–349, 1996). Specifically, I conduct two neurophenomenological analyses of tool-perception and tool-use, examining both how distance modulates affordance-perception and how tool-use remaps bodily space via the withdrawal of tools from intentional-objects into co-constituting motor-intentionality itself. I conclude by briefly distinguishing this interpretation of spatial cognition from cognitivist frameworks. Thereafter, I briefly highlight the temporal scaffolding underlying PPS while conceptually grounding my account within Embodied Simulation Theory (Gallese, Reti, Saperi, Linguaggi, (1), 31–46, 2018). What is at stake is thus both an explicitly embodied-enactive account of bodily space that is qualitative and situational instead of quantitative and positional, as well as a viable, interdisciplinary strategy for unifying pre-reflective cognition with neurophysiological data.
Skin applications of cannabidiol: sources, effects, delivery systems, marketed formulations and safety

AbstractIn recent decades, the therapeutic potential of cannabinoids and analogous compounds has been intensively investigated. The endocannabinoid system has already been identified in the skin and, although much remains to be discovered about its contribution and importance for the maintenance of skin homeostasis, it has been increasingly associated as promising for dermatological disorders’ management. Cannabidiol (CBD), the main non-intoxicating phytocannabinoid in cannabis, has been shown to have hydrating, sebostatic, antipruritic, antimicrobial, anti-inflammatory, antioxidant, wound healing, photoprotective, anti-fibrotic and antitumoral, as well as modulating hair growth. Thus, CBD has gained attention concerning its application in cutaneous pathologies such as atopic dermatitis, psoriasis, acne, epidermolysis bullosa, systemic sclerosis, seborrheic dermatitis, androgenetic alopecia and cutaneous melanoma, although its bioactivities still lack scientific evidence and some of its mechanisms of action remain to be elucidated. Given its physicochemical characteristics, its topical administration becomes challenging, and it is necessary to develop new technological strategies to overcome the skin intact barrier. This review describes the latest evidence that exists on the application of CBD to the skin, the problems inherent to its chemical structure and that compromise its cutaneous administration, and the different strategies and formulations that have been studied to improve it, also clarifying some CBD-containing cosmetics products that are already available on the market.

How academic opinion leaders shape scientific ideas: an acknowledgment analysis
Authors: Doehne Malte , Herfeld Catherine 
Published: March 2023

AbstractIn this paper, we examine how a research institution’s social structure and the presence of academic opinion leaders shaped the early adoption of a scientific innovation. Our case considers the early engagement of mathematical economists at the Cowles Commission with John von Neumann and Oskar Morgenstern’sTheory of Games and Economic Behavior.We argue that scholars with administrative leadership functions who were not only scientifically but also organizationally central—in our case Jacob Marschak, the director of research at Cowles—played a crucial role in promoting the early adoption of theTheory of Games. We support our argument with a scientometric analysis of all acknowledgments made in 488 papers published from 1944 to 1955 in the two main research paper series at the Cowles Commission. We apply blockmodeling techniques to the acknowledgments network to reconstruct the formal and informal social structure at Cowles at the time. Our case study emphasizes the importance of formal and informal social structures and the research agendas of academic opinion leaders to explain the early engagement with and adoption of innovative scientific ideas. Studies of the early adoption of scientific theories can benefit from complementary perspectives on the role of academic opinion leaders and scientists in explaining theory adoption.
Fear, Angst, and the “Startling Unexpected”. Three Figures of Teaching During the COVID-19 Pandemic
Authors: d’Agnese Vasco 
Published: March 2023

AbstractIn this paper, I focus on teachers’ lived experiences during the COVID-19 outbreak. Specifically, I explore the emotional impact the abrupt shift to online teaching had on teachers’ work and life throughout the various phases of the lockdown. I develop my argument by analyzing teachers’ everyday work, using a qualitative approach, and constructing a small-scale empirical study. Philosophically, my attempt is phenomenologically developed and is framed by Heidegger’s and Arendt’s thoughts. Methodologically, my attempt falls within an emerging research horizon that combines educational philosophy with empirical research. Drawing from research data, I argue that teachers’ experience bears witness to a deep modification of the schooling space-time, namely, the horizon in which the very perception of students, themselves, and teaching arise. In the case of teachers experiencing discomfort, fear, and even angst, the totality of their gestures and emotions was, as it were, swallowed by this unknown and disquieting horizon; teachers in distress were experiencing the collapse of any projecting without being freed by projecting itself. In the case of teachers experiencing feelings of fulfillment and even joy, a different horizon was allowed to emerge. Such a different space-time, rather than producing a sense of distance and alienation, created a new intimacy and nearness, which allows for a different attitude toward the topics and the educational community. Students became more sensitive, susceptible to transformation, and open to what was being said. At the same time, relationships were caught in a new web of meanings that transcended them, thus giving birth to an educational experience in its own right. I conclude with some remarks about the building of the educational community.
Efficient design of a quantum absolute-value circuit using Clifford+T gates

Published: March 2023

AbstractCurrent quantum computers have a limited number of resources and are heavily affected by internal and external noise. Therefore, small, noise-tolerant circuits are of great interest. With regard to circuit size, it is especially important to reduce the number of required qubits. Concerning to fault-tolerance, circuits entirely built with Clifford+T gates allow the use of error correction codes. However, the T-gate has an excessive cost, so circuits with a high number of T-gates should be avoided. This work focuses on optimising in such terms an operation that is widely used in larger circuits and algorithms: the calculation of the absolute-value of two’s complement encoded integers. The proposed circuit halves the number of required T gates with respect to the best circuit currently available in the literature. Moreover, our circuit requires at least 2 qubits less than the other circuits for such an operation.

Abstract
Diabetes mellitus is a worldwide problem characterized by hyperglycemia as well as the damage of the microscopic structure of the beta cells of Langerhans pancreatic islets. In the present study, the histological, immunohistochemical, morphometric, and biochemical alterations to pancreatic beta cells in streptozocin (STZ)-induced diabetes were assessed in rats treated with curcumin (CU) (100 mg/kg/day) or nano-curcumin (nCU) (100 mg/kg/day) for 1 month. Twenty-four adult male Wistar albino rats were distributed into four groups: the nondiabetic control group, the diabetic untreated group, and two diabetic groups treated with CU or nCUR, respectively. Blood glucose, serum insulin levels, and lipid profile were measured. The pancreatic tissues were collected and processed into paraffin sections for histological and immunohistochemical examination, oxidative stress markers, and real-time PCR expression for pancreatic and duodenal homeobox 1 (PDX1). The insulin expression in beta cells was assessed using immunohistochemistry. Morphometrically, the percentage area of anti-insulin antibody reaction and the percentage area of islet cells were determined. STZ-induced deteriorating alteration in beta cells led to declines in the number of functioning beta cells and insulin immunoreactivity. In STZ-treated rats, CU and nCUR significantly reduced blood glucose concentration while increasing blood insulin level. It also caused a significant increase in the number of immunoreactive beta cells to the insulin expression and significant reduction of the immunoreactive beta cells to the caspase-3 expression. In conclusion, CU and nCUR could have a therapeutic role in the biochemical and microscopic changes in pancreatic beta cells in diabetes-induced rats through STZ administration with more bio-efficacy of nCUR.

AbstractPharmaceuticals can be considered a global threat to aquatic ecosystems due to their pseudo-persistence and their potential toxicity towards non-target species. Amoxicillin (AMX) and carbamazepine (CBZ) and their mixture (1:1) were investigated on the marine copepod Tigriopus fulvus (Fischer, 1860) considering both acute and chronic endpoints. While acute and chronic exposure did not directly affect survival, reproductive endpoints were affected like the mean egg hatching time that was significantly longer than the negative control for treatments with AMX (0.789 ± 0.079 μg/L), CBZ (8.88 ± 0.89 μg/L), and AMX and CMZ as a mixture (1.03 ± 0.10 μg/L and 0.941 ± 0.094 μg/L), in that order.
