Children as Levels: Early Understandings of Reading Development Conceptualized by Preservice Teachers
Authors: Fraser Andrea 
Published: November 2024

This qualitative study surfaced beliefs around reading instruction and reading development at the onset of an elementary literacy methods course. Prior understandings and knowledge around reading instruction and reading acquisition emerge through various experiences and have the potential to contradict notions presented by teacher educators. This inquiry explored prior beliefs held by five preservice teachers (PSTs) about the nature of reading and the teaching of reading, drawing on a thematic analysis (Braun & Clarke, 2006) of a pre-course survey. Results indicated that early understandings of reading development and pedagogy appear to rely on levelling systems for assessing and identifying students’ acquisition of reading skills, as well as organizing students into levels for instruction. Beliefs that reading development progresses through a levelled gradient are problematic for both teacher and student, shifting attention away from the complex nature of reading acquisition and the skills required to develop proficiency. While no generalizable statement can be made regarding PSTs’ most frequently held beliefs, this pilot study puts forward the idea that understanding PSTs’ prior beliefs is a critical part of teacher education. Intentional opportunities to unpack prior beliefs and understandings may offer insight for teacher educators to engage students in discourse and experience cognitive dissonance around inconsistencies, making space for learning and unlearning.

“Self” in Self-Study: Alongside Stories as Indigenously Understood Inquiry
Authors: Hill Cher , Sivia Awneet , Kelly Vicki , Rosehart Paula , Keliipio Kau'i 
Published: November 2024

As part of our ethical responsibilities as scholar-practitioners and community members living as uninvited guests on Indigenous territories, we engaged in a collaborative inquiry to explore ways in which Indigenous pedagogies and worldviews extend understandings of self within self-study research. Over several years, we engaged in reflective conversations about our respective tensions, challenges, and successes in the effort to decolonize and Indigenize our pedagogies and research. These conversations moved us over time to a particular orientation as we shared our life stories as educators and women. We began by documenting our experiences and reflections at each meeting and shared in meaning making how our orientations shifted to ways of being in relation. The emerging synergies of our relationality led us to name our experiences “alongside stories,” in which we made meaning of the intersections and nuances between forms of self-study research and Indigenous Ways of Knowing. In sharing the alongside stories, we re-presented our collaborative understandings of inquiry as interweavings. These interweavings allowed us to explore how our knowledge and belief systems could be intertwined and disentwined to reveal resonances and particularities. Our exploration led us to reframe inquiry and self-study as Indigenously understood.

Background. Antibiotics were widely used during the COVID-19 pandemic, which may have led to an increase in the number and diversity of antibiotic resistance genes. Most studies assessing the human resistome during this period were conducted over a short period of time and on diﬀerent cohorts of people. In this case, the most informative approach is to study the composition of the resistome in people who have and have not recovered from COVID-19, using paired stool samples obtained before and after the pandemic.The aim of the study was to assess the prevalence of antibiotic resistance genes in the intestinal microbiota of the adult population of Arkhangelsk city before and after the COVID-19 pandemic.Material and Methods. The study included a random population sample of residents of Arkhangelsk who provided paired stool samples at intervals of ﬁve years. The study procedure included surveying and identiﬁcation of antibiotic resistance genes in stool samples using polymerase chain reaction. Processing of the obtained data was carried out in the R language.Results. The samples of almost all participants contained genes that cause resistance to macrolides: mefA and ermB. The frequency of glycopeptide resistance genes (vanA and vanB) in post-pandemic samples decreased signiﬁcantly. There is a trend towards an increase in the number of antibiotic resistance genes among patients hospitalized for COVID-19 compared to outpatients. The proportion of macrolide resistance genes shifted toward an increased relative representation of mefA in post-pandemic samples.Conclusion. The resistome of study participants did not undergo signiﬁcant changes during the COVID-19 pandemic, except for a decrease in the prevalence of glycopeptide resistance genes and a change in the ratio of macrolide resistance genes.

Background. The spread of pathogenic antibiotic-resistant microorganisms often leads to the ineﬃciency of antimicrobial therapy. One of the solutions to this problem is the search for new active natural antibiotics.The aim of the study. The search for producers that show antibiotic activity in relation to resistant test microorganisms, including those from the ESKAPE group, in the natural environment. The object of the study was bacteria isolated from a poorly studied environment — the soil of the tropical desert, namely the soil of the Sinai Peninsula.Methods. Soil suspensions were sown on universal sterling agar environment No. 2 Gause, suitable for the growth of many bacteria and fungi. The isolated microorganisms were identiﬁed by morphological characteristics and by the analysis of ribosomal RNA genes. Deep cultivation was carried out in nutrient media of various compositions under aeration conditions. Test strains of gram-positive and gram-negative bacteria, as well as fungi, were used to evaluate antimicrobial activity.Results. 38 cultures of microorganisms were isolated: 9 strains of fungi, 5 strains of streptomycetes, 2 strains of Bacillus subtilis, and 22 strains of representatives of other taxonomic groups of bacteria. 5 strains of streptomycetes and 2 strains of B. subtilis exhibit antibiotic activity, in particular against resistant pathogens of the ESKAPE group, namely methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Escherichia coli, as well as Mycobacterium smegmatis — a preliminary test in the search for anti-tuberculosis drugs.Conclusion. The search for antibiotic producers from the isolated desert soil was productive, due to the fact that a quarter of the isolated bacterial strains exhibited antimicrobial activity, even against multidrug-resistant test strains. Bio-synthesis conditions have been developed for subsequent isolation and chemical study. The most promising strains are Streptomyces rochei INA 01452 and INA 01509, as well as Streptomyces sp. INA 01523.

Published: November 2024

Abstract
The presence of another planetary companion in a transiting exoplanet system can impact its transit light curve, leading to sinusoidal transit-timing variations (TTV). By utilizing both χ
2 and rms analysis, we have combined the TESS observation data with an N-body simulation to investigate the existence of an additional planet in the system and put a limit on its mass. We have developed CMAT, an efficient and user-friendly tool for fitting transit light curves and calculating TTV with a theoretical period, based on which we can give a limit on its hidden companion’s mass. We use 260 hot Jupiter systems from the complete TESS data set to demonstrate the use of CMAT. Our findings indicate that, for most systems, the upper mass limit of a companion planet can be restricted to several Jupiter masses. This constraint becomes stronger near resonance orbits, such as the 1:2, 2:1, 3:1, and 4:1 mean-motion resonance, where the limit is reduced to several Earth masses. These findings align with previous studies suggesting that a lack of companion planets with resonance in hot Jupiter systems could potentially support the high-eccentricity migration theory. Additionally, we observed that the choice between χ
2 or rms method does not significantly affect the upper limit on companion mass; however, χ
2 analysis may result in weaker restrictions but is statistically more robust compared to rms analysis in most cases.

Abstract
Thanks to the rapidly increasing time-domain facilities, we are entering a golden era of research on gamma-ray bursts (GRBs). In this Letter, we report our observations of GRB 240529A with the Burst Optical Observer and Transient Exploring System, the 1.5 m telescope at Observatorio de Sierra Nevada, the 2.5 m Wide Field Survey Telescope of China, the Large Binocular Telescope, and the Telescopio Nazionale Galileo. The prompt emission of GRB 240529A shows two comparable energetic episodes separated by a quiescence time of roughly 400 s. Combining all available data on the GRB Coordinates Network, we reveal the simultaneous apparent X-ray plateau and optical rebrightening around 103–104 s after the burst. Rather than the energy injection from the magnetar as widely invoked for similar GRBs, the multiwavelength emissions could be better explained as two shocks launched from the central engine separately. The optical peak time and our numerical modeling suggest that the initial bulk Lorentz factor of the later shock is roughly 50, which indicates that the later jet should be accretion driven and have a higher mass loading than a typical one. The quiescence time between the two prompt emission episodes may be caused by the transition between different accretion states of a central magnetar or black hole, or the fallback accretion process. A sample of similar bursts with multiple emission episodes in the prompt phase and sufficient follow-up could help to probe the underlying physics of GRB central engines.
Detection of 19 lt-yr Long Bipolar Jets from Interacting Binary KX And
Authors: Ziegenbalg Stefan 
Published: November 2024

Abstract
Bipolar jets with an apparent length of 20′ ejected from KX And have been discovered in the first data release of the Northern Sky Narrowband Survey. KX And is a well-studied interacting binary with mass transfer through Roche lobe overflow at a distance of about 760 pc. However, the faint jets, which are visible in Hα light, have been overlooked in the past. With a known inclination of i ≈ 50° of the binary system, this leads to a true length of the jets of about 19 lt-yr (5.8 pc) in each direction.
The Impact of AGN Jet Speed on the Lyα Forest Flux Power Spectrum
Authors: Pirecki Megan , Tillman Megan Taylor , Burkhart Blakesley 
Published: November 2024

Abstract
The Lyα forest has received attention recently as a constraint for galactic feedback. In particular, different active galactic nucleus (AGN) feedback models have been shown to have varying effects on the Lyα forest. Some show minimal effect, while others have shown dramatic effects that may be observable given current data. Out of the various Lyα forest statistics, the 1D transmitted flux power spectrum (P1D) has shown the most potential in its ability to distinguish between feedback models. In this work we analyze the effects that AGN jets in the Simba simulation have on the Lyα forest P1D. We specifically explore how changing the maximum speed of the jets impacts the predicted P1D across a wide range of redshifts (0.1 < z < 2). We find that the impact of changing the jet speed on the P1D is most dramatic at lower redshifts (z < 1) and k ≳ 2 × 10−2.

Abstract
Comparing how an asteroid appears in space to its ablation behavior during atmospheric passage and finally to the properties of associated meteorites represents the ultimate probe of small near-Earth objects. We present observations from the Lowell Discovery Telescope and multiple meteor camera networks of 2022 WJ1, an Earth impactor that was disrupted over the North American Great Lakes on 2022 November 19. As far as we are aware, this is only the second time an Earth impactor has been specifically observed in multiple passbands prior to impact to characterize its composition. The orbits derived from telescopic observations submitted to the Minor Planet Center and ground-based meteor cameras result in impact trajectories that agree to within 40 m, but no meteorites have been found as of yet. The telescopic observations suggest a silicate-rich surface and thus a moderate-to-high albedo, which results in an estimated size for the object of just D = 40−60 cm. Modeling the fragmentation of 2022 WJ1 during its fireball phase also suggests an approximate 0.5 m original size for the object as well as an ordinary chondrite-like strength. These two lines of evidence both support that 2022 WJ1 was likely an S-type chondritic object and the smallest asteroid compositionally characterized in space. We discuss how best to combine telescopic and meteor camera data sets, how well these techniques agree, and what can be learned from studies of ultrasmall asteroids.

Published: November 2024

Based on unique morphological features and phylogenetic analysis of combined LSU and ITS sequences, Paramirandina guttulata is established as the third species in Paramirandina, along with P. aquatica and P. cymbiformis. All three species of Paramirandina were reported from freshwater habitats in China.
Paramirandina guttulata sp. nov. is a morphologically conspicuous hyphomycetes species, collected from a plateau lake (Dujuanhu Lake) in Yunnan Province, China. The key distinguishing characteristics of P. guttulata are scattered or gregarious conidiophores, polyblastic, terminal, sympodial conidiogenous cells and fusiform, cymbiform, 4–6-septate, guttulate, hyaline conidia that are solitary or in chains and with truncate base and obtuse apex. Detailed descriptions and illustrations are provided for the new species.
Símbolos del eurocomunismo. Representaciones e imaginario en la cartelería del PCI y el PCE (1975-1978)
Authors: Donofrio Andrea , Rueda Laffond José Carlos 
Published: November 2024

El artículo aborda las claves iconográficas y simbólicas presentes en la cartelería del Partido Comunista Italiano (PCI) y el Partido Comunista de España (PCE) de mediados de los años setenta. Dicho contexto se caracterizó por el tránsito de la clandestinidad a la legalización y la concurrencia del PCE a las elecciones de 1977, en España, y, en Italia, por el compromesso storico y el creciente respaldo social y electoral al PCI (comicios regionales y comunales de 1975, generales de 1976). El texto destaca las particularidades de los respectivos mensajes gráficos, sus paralelismos o la influencia de ciertas representaciones italianas en España. También considera que el cartel sirvió de soporte para un amplio imaginario que dio forma visual al eurocomunismo, un implícito eje integrador que permitió articular la identidad visual de ambos partidos.
IMPACT OF ROAD GRID TEMPORAL AND SPATIAL CHANGES ON THE ECOSYSTEM IN THE HIGH-ALTITUDE PLATEAU AREA: AN EMPIRICAL STUDY
Authors: Zhang Jingxiao , Li Hui , Cao Shuwen , Philbin Simon P. , Cheng Liyuan , Skitmore Martin 
Published: November 2024

ABSTRACT
This empirical research utilized geographic information system (GIS) data and involved kernel density estimation (WKDE), ecological footprint modeling, landscape index analysis, and spatial analysis methods. A plateau landscape ecological risk model is constructed, and the temporal and spatial changes in the road network pattern and the landscape ecological risk in the region in 2012 and 2020 are investigated. The study results identify that the expansion of the road network led to a rapid increase in construction land area and a decrease in cultivated land area. However, there is little impact on other landscape types. The study reveals that road network expansion leads to landscape ecological risk changes, primarily in low-altitude urban centers. The risk levels decrease with increasing ecological risk levels, with the proportion of road level lengths increasing and decreasing. Landscape ecological risk and road level is correlated. This study will interest practitioners engaged in ecosystem management, infrastructure planning, and transportation systems development, as well as researchers in these and related areas.
Le transfert avorté de la capitale de la Côte d’Ivoire à Yamoussoukro de 1983 à 2012 : les textes législatifs en cause
Authors: Kouadio Kouakou Didié 
Published: November 2024

Cette recherche questionne les insuffisances des textes législatifs sur le transfert de la capitale politique et administrative de la Côte d’Ivoire à Yamoussoukro. Ainsi, elle entend faire ressortir les germes de l’échec du transfert effectif de la capitale ivoirienne d’Abidjan à Yamoussoukro à travers les lois et décrets votés à cet effet. À partir d’une approche historique, juridique et sociologique, l’étude fait ressortir une loi de transfert ambiguë adoptée à la hâte en mars 1983. Cette loi reste imprécise sur la zone susceptible d’accueillir les bâtiments administratifs et les institutions de la république. Le décret no 97-177 du 17 mars 1997, censé corriger les imperfections de la loi de 1983, n’en demeure pas moins tendancieux. Il ne fait pas mention des purges des droits coutumiers et de l’indemnisation des populations impactées par la délimitation de la Zone administrative et politique (ZAP). En 2002, le décret no 2002-646 du 30 octobre 2002 portant transfert effectif de la capitale à Yamoussoukro se heurte aux conflits fonciers entre communautés villageoises de la ZAP. Au lendemain de la crise post-électorale, le décret no 2012-02 du 9 janvier 2012 consacre la suspension du transfert effectif de la capitale. Au regard de tous ces décrets, il est évident que les textes législatifs sont en partie responsables de l’échec du transfert effectif de la capitale à Yamoussoukro.
Écrits épiques royaux et identité politique guerrière au royaume bamoun (Cameroun)
Authors: Pemboura Aïcha 
Published: November 2024

Cet article démontre comment Histoire
et coutumes des Bamum, un ouvrage de l’emblématique souverain
bamoun Ibrahim Njoya, a contribué à construire et à diffuser, dans la
mémoire culturelle de la communauté bamoun, une culture stratégique de
la guerre fondée essentiellement sur le souvenir des glorieux souverains
guerriers bamoun et des stratégies belliqueuses dont ceux-ci usaient. La
grandeur perçue et perpétuée du royaume bamoun dans le Cameroun
aujourd’hui tient à la diffusion d’une histoire épique des traditions
martiales et de la résistance aux conquêtes extérieures. C’est par la
transmission d’écrits vernaculaires mais aussi par l’oralisation de ces
textes — en particulier par les héritiers d’une notabilité palatine
bamoun devenus les dépositaires des traditions du royaume — qu’est
reconduite cette épopée guerrière, mythe fondateur d’une identité
politique bamoun constamment ravivée.
