How Does a Low Surface Brightness Galaxy Form Spiral Arms?
Authors: Narayanan Ganesh , A. G. Anagha , Banerjee Arunima 
Published: September 2024

Abstract
The formation and evolution of spiral arms in low surface brightness galaxies (LSBs) are not well understood. We study the dynamics of spiral arms in two prototypical LSBs, FGC 568-VI and FGC 568-01, using both analytical models and N-body + hydrodynamical simulations. We first consider the disk as a two-component system of gravitationally coupled stars and gas in the force field of a spherical dark matter halo, subjected to local, nonaxisymmetric perturbations. However, no local spirals are formed. We next assume the disk to be a one-component system of stars in the net gravitational potential of a galaxy with a spherical dark matter halo perturbed by a global m = 2 instability. In this case, the growth time for spiral formation was low, equal to 0.78 and 0.96 Gyr, respectively, corresponding to a few dynamical times of the galaxies. Finally, we simulate the LSBs using the N-body + hydrodynamical simulation code RAMSES. Our results show that a quadrupolar field associated with an oblate halo with an axial ratio of 0.7 is necessary to drive a long-lived global spiral in the LSB disks. Further, feedback corresponding to a supernova mass fraction of ∼0.05 is essential to comply with the observed stellar surface density. The simulated spirals survive for about 10 dynamical times and the average pattern speed lies between 10 and 15 km s−1 kpc−1. The spiral arms thus formed are therefore a transient global pattern driven by the tidal field of the oblate dark matter halo.

Abstract
We present an in-depth, high-resolution spectroscopic analysis of the M dwarf K2-18, which hosts a sub-Neptune exoplanet in its habitable zone. We show our technique to accurately normalize the observed spectrum, which is crucial for a proper spectral fitting. We also introduce a new automatic, line-by-line, model-fitting code, AutoSpecFit, which performs an iterative χ
2 minimization process to measure individual elemental abundances of cool dwarfs. We apply this code to the star K2-18, and measure the abundance of 10 elements: C, O, Na, Mg, Al, K, Ca, Sc, Ti, and Fe. We find these abundances to be moderately supersolar, except for Fe, with a slightly subsolar abundance. The accuracy of the inferred abundances is limited by the systematic errors due to uncertain stellar parameters. We also derive the abundance ratios associated with several planet-building elements such as Al/Mg, Ca/Mg, Fe/Mg, and (a solar-like) C/O = 0.568 ± 0.026, which can be used to constrain the chemical composition and the formation location of the exoplanet. On the other hand, the planet K2-18 b has attracted considerable interest, given the JWST measurements of its atmospheric composition. Early JWST studies reveal an unusual chemistry for the atmosphere of this planet, which is unlikely to be driven by formation in a disk of unusual composition. The comparison between the chemical abundances of K2-18 b from future JWST analyses and those of the host star can provide fundamental insights into the formation of this planetary system.
Different Influence of Gas Accretion on the Evolution of Star-forming and Non-star-forming Galaxies

Published: September 2024

Abstract
Using integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we investigate the spatially resolved properties and empirical relations of a star-forming galaxy and a non-star-forming galaxy hosting counterrotating stellar disks (CRDs). The DESI g, r, z color images reveal no evidence of merger remnants in either galaxy, suggesting that gas accretion fuels the formation of CRDs. Based on the visible counterrotation in the stellar velocity field, we can fit a spatial boundary to distinguish the inner and outer regions dominated by two stellar disks in each galaxy. In the inner region of the star-forming CRDs, stars are corotating with ionized gas, and the stellar population is younger. Comparison of the star-forming main-sequence relations between the inner and outer regions reveals enhanced star formation in the inner region. Given the abundant preexisting gas in the star-forming galaxy, collisions between preexisting and external gas efficiently consume angular momentum, triggering star formation in the inner region. Conversely, in the outer region of the non-star-forming CRDs, stars are corotating with ionized gas, and the stellar population is younger. Comparison of the stellar mass–metallicity relations between the inner and outer regions indicates enriched gas-phase metallicity in the outer region. Considering the less abundant preexisting gas in the non-star-forming galaxy, external gas could preserve angular momentum, fueling star formation in the outer region. Overall, gas accretion exhibits different influences on the evolution of star-forming and non-star-forming galaxies.
Quantifying the High Early Solar Cosmic-Ray Flux with Cosmogenic Neon Isotopes in Refractory Minerals
Authors: Yang Xin , Ciesla Fred J. , Heck Philipp R. 
Published: September 2024

Abstract
An enhancement in the activity of the early young Sun resulting in a high charged particle flux has been invoked to explain excesses in spallation-induced nuclides in primitive planetary materials. Astronomical observations of energetic outbursts of young stellar objects (YSOs) also support the idea of an active young Sun. However, the early solar cosmic-ray (SCR) flux has not been well constrained. Here we use measured concentrations of SCR-produced nuclides that formed and are preserved in meteoritical hibonite and spinel, some of the solar system’s oldest solids, and physical models for dust transport in the early protoplanetary disk to determine the magnitude of the early SCR flux. We focus our attention on cosmogenic neon, which cannot have been inherited from precursors and can only be produced in situ in solids. Our modeled effective exposure time to SCRs for these solids is very short, on the order of years. This indicates that the young Sun’s SCR flux recorded in refractory mineral hibonite was up to ∼7 orders of magnitude higher than the contemporary level. Our flux estimate is consistent with the >105× enhanced flux inferred from astronomical observations of greatly enhanced flare activities of YSOs.

Published: September 2024

Although there have been many recent taxonomic revisions and large-scale faunistic surveys focusing on spiders from Jiangxi Province, many taxa still remain unknown, such as the Anyphaenidae spiders. Therefore, none of the anyphaenid species has been recorded from this Province.
Anyphaenidae spiders were collected from Jinggangshan National Nature Reserve, Jiangxi Province, China, during the past ten years. A new tube spider species, Anyphaena leidashi Yao & Liu, sp. nov. is diagnosed, described and illustrated. Moreover, three species including A. mogan Song & Chen, 1987, A. wuyi Zhang, Zhu & Song, 2005 and Rathalos xiushanensis (Song & Zhu, 1991) are recorded from Jiangxi Province for the first time. Distributions records are given for all investigated species.
Le précurseur
Authors: Schlanger Judith 
Published: September 2024

Le précurseur est défini par sa fonction par rapport à ce qui est à venir, et posé comme relatif à un autre terme qui n’est pas encore là, il est l’initiateur ou l’avant-coureur d’une réalité future qui se réalisera pleinement, mais pas en lui. C’est une notion moderne liée à une perception moderne de la durée historique et de l’intelligibilité historique. Elle appartient à une histoire culturelle du changement, comme la notion de chef-d’œuvre, soulignant en même temps, quand la distance est grande, les risques et les contingences de la « reprise ». Se joue ainsi une relation à trois termes, entre le précurseur, ce qui constitue sa reprise, et éventuellement l’instance qui attribue la relation entre les distants. Breton revendiquant une liste variable de précurseurs, ou Borgès relevant de très nombreux auteurs qu’il perçoit comme précurseurs de Kafka, fournissent des exemples de la richesse et de la profondeur d’un tel paysage culturel.
Perceptions and Lived Experiences of Nurses After Completion of a Perinatal Nurse Residency Program
Authors: Zinke Cassandra R. 
Published: September 2024

Background
This study was designed to explore the perceptions and lived experiences of new graduate or new-to-specialty labor and delivery nurses. These nurses had completed a perinatal nurse residency program at a high-risk metropolitan medical center in the Pacific Northwest region of the United States.

Method
Eight nurses were interviewed for this study with qualitative individual interviews. Qualitative content analysis was used.

Results
Three main themes emerged: assimilating a specialized knowledge base and skill sets, navigating challenging circumstances, and coping with the transition to independence.

Conclusion

Nurse residency programs can ease the transition to practice in the labor and delivery specialty. Revisions to future perinatal residency programs should include enhanced preceptor education, prolonged night shift orientation, assessment of nurse learning style and needs, and increased consistency of debriefing after traumatic events.

Attachment traumatology and dyadic completion: Toddler trauma, ten years post-treatment
Authors: Riordan Joseph 
Published: September 2024

Orientation: Research to elucidate trauma as a contagion in attachment traumatology began in 2014 with the construct of dyadic completion as a therapeutic goal for a traumatised toddler. Further research revealed secure phylogenetic attachment (SPA) as the antithesis of trauma, Attachment Focussed-Somatic Experiencing (AF-SE) as an efficacious treatment for dyadic trauma and interpersonal neurosynchronistic phylogenesis (INP) as a construct to explain how phylogenetic attachment dynamics are transposed neurosynchronistically in dyads throughout communities. These phenomena offer insight into community mental health.Research purpose: The purpose of the study was to elucidate neurosynchronistic constructs in attachment traumatology to examine treatment outcomes longitudinally.Motivation for the study: Assessed psychometrically, Little Bill (LB) was reviewed to examine his mental health and phylogenetic attachment dynamics ten years post-treatment.Research approach and/or design and method: A longitudinal single-case design was followed using psychometric assessments and clinical interviews with three family members.Main findings: Outcomes support dyadic completion as an effective treatment confirmed by long-term efficacy.Implications for practice: Dyadic completion in AF-SE is an effective treatment for dyadic trauma.Contribution and/or value-add: Dyadic completion resolves dyadic trauma phylogenetically. Trauma and SPA may now be considered as interpersonal, neurosynchronistic and phylogenetic phenomena impacting attachment and community mental health.

Published: September 2024

Abstract

Background:
Antibiotics are among the most commonly prescribed drugs. Unnecessary use of antibiotics is particularly concerning because antibiotics may be associated with a number of adverse drug events.

Aim:
The study was designed to detect the association between pulmonary embolism and antibiotics by disproportionality analysis in the Food and Drug Administration database of Adverse Event Reporting System (FAERS) using data mining algorithms (DMAs).

Materials and Methods:
A retrospective case/noncase disproportionality analysis was performed in the FAERS database. This study was based on adverse events (AEs) reported to FAERS from 2004 Q1 to 2022 Q3. Reporting odds ratio (ROR), proportional reporting ratio (PRR), and information component (IC) were applied to measure the disproportionality in reporting. A positive signal of increased AE risk was defined as ROR >1, Chi-square >4, PRR R2 with the number of cases >3, and IC >0.

Results:
Total AEs in the FAERS database from 2004 Q1 to 2022 Q3 were found to be 26,555,430. Among which 80,809 reports of pulmonary embolism were considered. The same were selected for further analysis which showed that 11 antibiotics were reported for pulmonary embolism. The number of reports for minocycline, chloramphenicol, and moxifloxacin was found to be 113, 14, and 179. A significant potential signal was noted for minocycline (ROR – 2.87, Chi-square – 135.95, IC – 1.22), chloramphenicol (ROR – 3.35, Chi-square – 22.80, IC – 0.77), and moxifloxacin (ROR – 2.08, Chi-square – 99.37, IC – 0.83).

Conclusion:
This study found a statistically significant increased risk of reporting pulmonary embolism with minocycline, chloramphenicol, and moxifloxacin, although a causal relation cannot be definitively established.
Imágenes de la ciudad del futuro: cinco utopías argentinas (1882-1908)
Authors: Quereilhac Soledad 
Published: September 2024

El artículo se concentra en el análisis de cinco utopías publicadas en los años de entresiglos en la Argentina: “Mañana City” de Manuel Vázquez Castro; “La ciudad del siglo XXX” de Justo S. López de Gomara; “El Centenario” de Paul Groussac; La estrella del sur. A través del porvenir de Enrique Vera y González; y Buenos Aires en 1950 bajo el régimen socialista de Julio Dittrich. En todos los casos, los autores son inmigrantes de diferentes procedencias y formación previa, que dan a conocer sus relatos tanto en libros como en revistas. En estas cinco utopías -ejercicios de imaginación literaria de estatuto estético dispar- es posible rastrear nudos de la cultura del presente que aparecen como síntomas en la construcción del mundo futuro. Entre esos nudos, la proyección de una ciudad futura es uno de los problemas centrales en la medida en que permite la espacialización de la fantasía y su proyección panorámica. Me interesa identificar cuáles son las tensiones históricas que se cifran en la construcción ficcional de estas ciudades.
THE EFFECTS OF INTENSIVE TRAINING SESSIONS OF PEER FEEDBACK ON ENGLISH-MAJORED STUDENTS’ WRITING ACHIEVEMENT
Authors: Dong Mai Hung , Ut Nguyen Van 
Published: September 2024

The current study aimed to scrutinize the effect of using intensive training sessions of peer feedback in teaching writing skills to English-majored students in English as a Foreign Language. To do as, the study sample consisted of sixty students from two classes with an equivalent number of participants in both the control and experimental groups (30 students each), and their treatment was implemented for eleven weeks. The experimental group received instruction through intensive training, while the control group was taught to use traditional methods. Both groups were administered pre-tests and post-tests, and their performance was evaluated by an instructor using the rubric of IELTS writing 2 based on a 10-point scoring system stipulated in the system of Vietnam education, which consists of four main domains, namely Task Achievements, Cohesion &amp; Coherence, Lexical Resource, and Grammatical Range &amp; Accuracy. The results indicated that both groups improved, but the experimental group demonstrated a relatively greater improvement compared to the control group. Furthermore, the most significant number of participants in the experimental group expressed a positive perception of the application of intensive training sessions of peer feedback in enhancing their writing skills. Thus, the proposed pedagogical implications of utilizing intensive training in peer feedback for academic writing in English as a foreign language are expected to bring innovation to the teaching of writing in Tra Vinh, which is located in the Mekong Delta region of Vietnam.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0770/a.php" alt="Hit counter" /></p>
ZUKUNFTSKOMPETENZEN AN DEN KAMERUNISCHEN HOCHSCHULEN – EINE REALITÄT ODER EINE UTOPIE? EINE EMPIRISCHE ANALYSE AM BEISPIEL DER DAF-LEHRERAUSBILDUNG
Authors: Ngoei Hamadou 
Published: September 2024

<p>Ausgehend von der Ausbildung der Deutschlehrer*innen an den pädagogischen Hochschulen analysiert und überprüft die vorliegende Studie, ob das Konzept der Zukunftskompetenzen in der kamerunischen Hochschulbildung eine existierende Realität oder ein Hirngespinst ist, d.h. ob die Hochschulbildung den Studenten ermöglicht, diese Kompetenzen zu erwerben. Eine Analyse der Lehrpläne, ergänzt durch eine Umfrage mittels Fragebogen, der den Absolventen der DaF-Lehrer*innenausbildung an der ENS von Yaoundé, Maroua und Bertoua im Jahr 2023 vorgelegt wurde, wurde durchgeführt. Die Analyse hat gezeigt, dass das Konzept der Zukunftskompetenzen bisher weder umgesetzt noch in den Lehrplänen als zu erreichendes Ziel erwähnt wird. Es ist jedoch festzustellen, dass die Studierenden im kamerunischen Hochschulwesen trotz dieser Tatsache und trotz der infrastrukturellen und ausstattungsbezogenen Mängel zwar Zukunftskompetenzen erwerben, aber auf niedrigem Niveau. Die vorliegende Studie schlägt vor, die Inhalte der Lehrpläne an den aktuellen Kontext und die Realitäten in Kamerun anzupassen, die Leistungsnachweise und die didaktischen Methoden an den Universitäten und Fachhochschulen zu überarbeiten.</p><p>Based on the training of German teachers at the Higher Teachers' Training College (HTTC), this study analyses and examines whether the concept of future skills in Cameroonian higher education is an existing reality or a fantasy, i.e. whether higher education enables students to acquire these competences. An analysis of the curricula was carried out, supplemented by a questionnaire survey of the 2023 graduates of the HTTC of Yaoundé, Maroua and Bertoua. The analysis showed that the concept of future skills has not yet been implemented or mentioned in the curricula as an objective to be achieved. It should be noted, however, that despite this fact and despite the infrastructural and equipment-related deficiencies, students in the Cameroonian higher education system acquire future skills, but at a low level. This study proposes to adapt the content of the curricula to the current context and realities in Cameroon and to revise the way students are evaluated and the didactic methods used in universities.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0775/a.php" alt="Hit counter" /></p>
POST-COLONIALISM AT ITS FINEST OR WHAT? EXPLAINING LA ‘FRANCAFRIQUE’ IN INTERNATIONAL RELATIONS
Authors: Manboah-Rockson Joseph Kwabena , Teng-Zeng Frank K. 
Published: September 2024

<p>This research examines the extent to which ‘Françafrique’ exists in the 21st century in view of the recent coup d’états’ in Mali, Burkina Faso, Niger and Gabon as case-studies. Four schools of thought are presented on ‘Françafrique’s’ robustness: <em>the Ideological school</em>, the <em>Regime theory school</em>, <em>the post-colonial theory </em>and <em>the Afrocentric School</em>. ‘Françafrique’ is analysed within five concrete, observable implications: the rationale for dismantling French Military bases in those countries, severing the deeply rooted preconceived financial servitude, military interventionism, corruption of African leaders, and an over-estimation of France’s economic interest in the continent. At the heart of all these lies a profound ignorance of bilateral and contextual dynamics in favour of outdated generalisations and economic relations with Metropolitan France. The overall trends and takeaways are evaluated, considering all implications and the changes over time. The question we ask is: is ‘Francafrique’ waning as ‘a policy of engagement’ within Francophone Africa? Alternatively, is Gaston Monnervile, the former French head of the Senate’s addressed in France, a truism when he said: <em>“Without overseas territory, today’s France would decline to be a lesser power needing to be liberated instead of the winner of WWII”. In contexture: ‘Are chickens coming home to roost’ as in </em>Former President François Mitterrand’s earlier assertion that <em>“without Africa, there would be no history of France in the 21<sup>st</sup> century.” </em></p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0711/a.php" alt="Hit counter" /></p>
