Abstract
The distribution of spin–orbit angles for systems with wide-separation, tidally detached exoplanets offers a unique constraint on the prevalence of dynamically violent planetary evolution histories. Tidally detached planets provide a relatively unbiased view of the primordial stellar obliquity distribution, as they cannot tidally realign within the system lifetime. We present the third result from our Stellar Obliquities in Long-period Exoplanet Systems (SOLES) survey: a measurement of the Rossiter–McLaughlin effect across two transits of the tidally detached warm Jupiter TOI-1478 b with the WIYN/NEID and Keck/HIRES spectrographs, revealing a sky-projected spin–orbit angle

. Combining this new measurement with the full set of archival obliquity measurements, including two previous constraints from the SOLES survey, we demonstrate that, in single-star systems, tidally detached warm Jupiters are preferentially more aligned than closer-orbiting hot Jupiters. This finding has two key implications: (1) planets in single-star systems tend to form within aligned protoplanetary disks, and (2) warm Jupiters form more quiescently than hot Jupiters, which, in single-star systems, are likely perturbed into a misaligned state through planet–planet interactions in the post-disk-dispersal phase. We also find that lower-mass Saturns span a wide range of spin–orbit angles, suggesting a prevalence of planet–planet scattering and/or secular mechanisms in these systems.
Effects of the Planetary Field on the Accretion Process of a Planet in the Final Stage of Giant Planet Formation
Authors: Tang Pengfei , Zhong Jiayong , An Weiming 
Published: August 2022

Abstract
Recent studies suggest that the magnetic field may play an important role in the formation of giant planets during the final stage of the formation process. In this paper, we construct a circumplanetary system around a planet that is in the final formation stage to investigate the effects of the planetary magnetic field on the accretion process of the planet at this stage. We find that at the early times of our magneto-hydrodynamic (MHD) simulation, the magnetic loops connecting the planet and the circumplanetary material inflate upward due to the build-up of the toroidal field pressure with magnetic islands forming inside the loops, which changes the flow pattern above the planet in comparison with the hydrodynamic case. We find that a low-density gap, which is produced by the strong magnetic pressure, appears along the disk’s surface and expands as the system evolves. Accompanied by the accretion flow above the disk surface, the disk surface field lines can reconnect with the magnetic loops anchored on the planet. Thus, the material above the disk’s surface can permeate into the loops anchored on the planet via reconnection and can be accreted to the planet through the loops. Comparing the results in the hydrodynamic and MHD simulations, we find that the mass accretion rate and the angular momentum transport rate from the infalling gas to the planet do not change apparently when the effects of the magnetic field are included, but these rates from the circumplanetary disk to the planet increase significantly by an order of magnitude.

Published: August 2022

Abstract
The O’Connell effect—the presence of unequal maxima in eclipsing binaries—remains an unsolved riddle in the study of close binary systems. The Kepler space telescope produced high-precision photometry of nearly 3000 eclipsing binary systems, providing a unique opportunity to study the O’Connell effect in a large sample and in greater detail than in previous studies. We have characterized the observational properties—including temperature, luminosity, and eclipse depth—of a set of 212 systems (7.3% of Kepler eclipsing binaries) that display a maxima flux difference of at least 1%, representing the largest sample of O’Connell effect systems yet studied. We explored how these characteristics correlate with each other to help understand the O’Connell effect’s underlying causes. We also describe some system classes with peculiar light-curve features aside from the O’Connell effect (∼24% of our sample), including temporal variation and asymmetric minima. We found that the O’Connell effect size’s correlations with period and temperature are inconsistent with Kouzuma's starspot study. Up to 20% of systems display the parabolic eclipse timing variation signal expected for binaries undergoing mass transfer. Most systems displaying the O’Connell effect have the brighter maximum following the primary eclipse, suggesting a fundamental link between which maximum is brighter and the O’Connell effect’s physical causes. Most importantly, we find that the O’Connell effect occurs exclusively in systems where the components are close enough to significantly affect each other, suggesting that the interaction between the components is ultimately responsible for causing the O’Connell effect.
Solar Chromospheric Network as a Source for Solar Wind Switchbacks

Published: August 2022

Abstract
Recent studies suggest that the magnetic switchbacks (SBs) detected by the Parker Solar Probe carry information on the scales of solar supergranulation (large scale) and granulation (medium scale). We test this claim using high-resolution Hα images obtained with the visible spectropolarimeters of the Goode Solar Telescope in Big Bear Solar Observatory. As possible solar sources, we count all the spicule-like features standing along the chromospheric networks near the coronal hole boundary visible in the Hα blue-wing but absent in the red-wing images and measure the geometric parameters of dense sections of individual flux tubes. Intervals between adjacent spicules located along the chromospheric networks are found in the range of 0.4–1.5 Mm (0.°03–0.°12) tending to be smaller than the medium scale of SBs. Interdistances between all pairs of the flux tubes are also counted and they appear in a single peak distribution around 0.7 Mm (0.°06) unlike the waiting-time distribution of SBs in a scale-free single power-law form. The length-to-diameter ratio of the dense section of flux tubes is as high as 6–40, similar to the aspect ratio of SBs. The number of spicules along a network can be as high as 40–100, consistent with numerous SBs within a patch. With these numbers, it is argued that the medium scale of SBs can be understood as an equilibrium distance resulting from a random walk within each diverging magnetic field funnel connected to the chromospheric networks.
Pourquoi édite-t-on les philosophes « classiques » en France au XIXe siècle ?
Authors: Barancy Félix 
Published: August 2022

L’édition des philosophes n’est pas conçue au XIXe siècle comme une tâche subalterne ou indifférente au travail philosophique lui-même. Mais elle n’est pas non plus réductible à des enjeux politiques, où il s’agirait seulement de se constituer des alliés et des ennemis dans une histoire réactualisée de la philosophie. Elle est au contraire pensée comme une pratique philosophique en elle-même. Les six études de ce dossier rendent compte de cette singularité de l’édition philosophique des classiques au XIXe siècle en France.
Agir en éditant. Les éditions de Pascal dans la seconde moitié du XIXe siècle et la formation du canon philosophique
Authors: Barancy Félix 
Published: August 2022

Les éditions et traductions représentent une part très importante du travail des philosophes français du XIXe siècle. Loin d’être envisagées comme des tâches subalternes, celles-ci sont comprises par leurs auteurs comme des œuvres elles-mêmes philosophiques. Dans cet article, nous montrons que pour pouvoir les considérer comme telles, il faut pouvoir identifier les raisons qui poussent l’auteur à s’intéresser à celui qu’il édite ainsi que les effets qu’il attend de sa publication dans le champ philosophique. En nous concentrant sur le cas de Blaise Pascal dans la seconde moitié du XIXe siècle, nous mettons en évidence la manière dont la question de son intégration au « canon » de la philosophie a conduit des philosophes étrangers, voire hostiles à sa pensée, à l’éditer : Ernest Havet et Léon Brunschvicg. Alors, il ne s’agissait pas pour eux de se déclarer « contre » Pascal, mais d’intégrer, en en pensant les spécificités, une édition de ses textes à leur propre projet philosophique.
Le libéralisme, combien de divisions ?
Authors: Quiriny Bernard 
Published: August 2022

Le libéralisme est une famille politique très vaste qui, si on la prend au sens large, réunit des auteurs aux positions diverses dont le seul point commun est l’attachement à la liberté. Il est alors indispensable, pour s’y repérer, de trouver des critères de classement. Les possibilités sont multiples : les libéraux peuvent être classés par nationalité, par époque, par champ d’intérêt privilégié (libéralisme économique, politique), etc. Le présent article propose de les classer selon deux critères, la conception de la liberté d’une part, le fondement utilitariste ou jusnaturaliste de l’attachement à la liberté d’autre part. Ces deux critères génèrent une grille de lecture opératoire en six catégories qui, sans épuiser le libéralisme, met en évidence des fractures décisives en son sein.
Gouverner les hommes : généalogie de la violence chez Ibn Khaldûn
Authors: Molino-Machetto Cédric 
Published: August 2022

Ibn Khaldûn a souvent été présenté comme un précurseur du matérialisme historique : le Machiavel ou le Marx arabe du XIVe siècle. Matérialiste, il l’est indéniablement dans sa méthodologie : l’origine du pouvoir est pensée à partir de la nécessité de contraindre les hommes à coopérer pour qu’ils puissent se reproduire dans leur existence matérielle. Mais à partir de son étude anthropologique des sociétés tribales et des sociétés étatiques, il a développé une analyse originale du pouvoir et de son corollaire : la violence. Le politique peut se concevoir, à partir de l’œuvre d’Ibn Khaldûn (de sa Muqaddima en particulier), comme l’organisation et la coordination de la violence. Celle-ci est vectrice d’unité sociale grâce à l’esprit de corps dans les sociétés tribales en étant dirigée vers l’extérieur : l’attaque des tribus ennemies et la défense de la communauté. Dans les sociétés étatiques, l’affaiblissement de l’esprit de corps nécessite l’établissement d’une autorité politique (wazi’), qui dirige la violence vers l’intérieur comme régulation de l’agressivité naturelle. Loin d’être la négation du politique, la violence est consubstantielle au politique : elle est la condition de possibilité de la préservation d’une totalité et d’une unité sociales. Lorsqu’un groupe social perd sa capacité de violence, la communauté s’effondre, à l’image de la ville de Damas ravagée par les troupes de Tamerlan sous les yeux impuissants du philosophe.
Modulating the Nordic Hamstring Exercise From “Zero to Hero”: A Stepwise Progression Explored in a High-Performance Athlete

Published: August 2022

BackgroundThe Nordic hamstring exercise (NHE) is commonly implemented to selectively improve eccentric knee-flexor strength. However, the standard version of the exercise (leveled shanks, extended hip joint) is too strenuous for most individuals, whose muscle activity rapidly decreases at extended knee angles. Hitherto, a gradual approach to the exercise has been missing. In this exploratory case study, we investigated elite performance to introduce a stepwise progression to the NHE.ObjectiveTo determine the extent to which exercise modifications (shank inclination, additional load, hip flexion) altered NHE mechanics.Data Collection and AnalysisOne male long jumper (age = 33 years, height = 171 cm, mass = 69 kg) with high-level expertise in the NHE performed 20 exercise variations. The corresponding kinematics, kinetics, and electromyographic activity of the biceps femoris long head (BFlh) and semitendinosus (ST) muscles were evaluated.ResultsExercise variations demonstrated gradually increased peak moments from 69% (zigzag pose) to 154% (inclined bent single-legged version) versus a standard NHE. Shank inclination and additional load elicited small to moderate effects on peak moments, BFlh, and ST (0.24 ≤ d ≤ 0.72), whereas hip flexion largely affected all tested variables (2.80 ≤ d ≤ 6.66), especially muscle activity (BFlh = −63%; ST = −55% of maximal voluntary isometric contraction).CommentaryThese insights will help practitioners and scientists design multifaceted stepwise NHE progressions by creating differentiated stimuli that best match the strength capacities of individuals and address their specific needs.

Published: August 2022

ContextBecause of the close proximity of the cochlea, vestibular apparatus, and shared neurovascular structures, the static postural control of athletes who are deaf or hard of hearing (D/HoH) may be different from that of athletes who are hearing. Limited research is available to quantify differences between these athletes.ObjectiveTo determine the effect of hearing status and stance condition on the static postural control of athletes.DesignCross-sectional study.SettingAthletic training facilities.Patients or Other ParticipantsFifty-five collegiate varsity athletes who were D/HoH (age = 20.62 ± 1.80 years, height = 1.73 ± 0.08 m, mass = 80.34 ± 18.92 kg) and 100 university club athletes who were hearing (age = 20.11 ± 1.59 years, height = 1.76 ± 0.09 m, mass = 77.66 ± 14.37 kg).Main Outcome Measure(s)Participants completed the Modified Clinical Test of Sensory Interaction and Balance on a triaxial force plate. Anteroposterior and mediolateral (ML) center-of-pressure (CoP) velocity, anteroposterior and ML CoP amplitude root mean square, and 95% ellipse sway area were calculated.ResultsAthletes who were D/HoH had a larger CoP velocity, larger ML root mean square, and larger sway area than those who were hearing (P values &lt; .01). A significant main effect of stance condition was observed for all postural control variables (P values &lt; .01).ConclusionsDuring the Modified Clinical Test of Sensory Interaction and Balance, athletes who were D/HoH demonstrated a larger sway area compared with athletes who were hearing. Therefore, individualized baseline assessments of static postural control may be warranted for athletes who are D/HoH as opposed to comparisons with existing normative data.

Vegetable soybean (Glycine max L. Merr.) is a highly nutritious crop in Africa whose attributes make it a product of choice to formulate diets with numerous human health benefits. The crop is still novel in West Africa, but is making inroads in many countries of the region. The objective of this study was to evaluate selected vegetable soybean varieties for agronomic performance and stability for fresh pod yield across Benin. Thirty-five vegetable soybean varieties were planted at three locations, namely Calavi, Grand-Popo and Sèmè, for two seasons. There was a significant variation (P < 0.05 ; P< 0.01 and P < 0.001) among genotypes for most quantitative traits; with highly significant environmental (P < 0.001) and GEI effects on fresh pod yield (P < 0.001). Genotype Maksoy 3N (15.9 t ha-1) had the highest fresh pod yield; while genotype AGS466 was the most stable across environments. Based on GGE, Sèmè-2 was the ideal environment for growing vegetable soybean in Benin. The study confirmed that vegetable soybean is well adapted to be grown in Benin and varieties AGS466, AGS346 and Ashorowase are candidates for wide cultivation in the country. Also, grain soybean varieties (S1079-6-7 and Maksoy 3N) are well suited to produce vegetable soybean in Benin.

VIETNAMESE HIGH SCHOOL EFL TEACHERS’ PERCEPTIONS TOWARD ONLINE TEACHING UNDER THE IMPACT OF COVID-19
Authors: Chi Vo Thi Le , Yen Phuong Hoang 
Published: August 2022

<p>The coronavirus disease case, commonly known as Covid-19, has spread internationally since March 2020. Approximately 100 countries, including Vietnam, closed their schools due to a public health emergency, according to UNESCO. Due to the circumstance, teachers were forced to convert from in-person instruction to online instruction. In the context of Covid-19, this study investigated how EFL high school instructors felt about online English language education. A descriptive design and a mixed-methods approach were utilized in this investigation. Six EFL high school teachers in the Mekong Delta were interviewed for this study to get their perspectives. The findings demonstrated that the participants' opinions on the usefulness and simplicity of online instruction during the Covid-19 epidemic were overwhelmingly positive. Despite the challenges they encountered when conducting their online classes, the teachers were able to show the proper attitude toward using technology to teach. The pedagogical implications of online teaching and learning are also meant to encourage the development of innovative teaching strategies in the setting of high schools in the Vietnamese Mekong Delta.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0595/a.php" alt="Hit counter" /></p>
REFLECTION OF ACADEMICIANS IN USING BLENDED LEARNING
Authors: Şengel Erhan , Aktaş Niyazi 
Published: August 2022

<p>Due to the current Covid-19 pandemic, the physical conditions of learning environments and the measures taken within the scope of combating the epidemic have made blended teaching practices, including distance education, much more important. With this study, it is aimed to shed light on the opinions and experiences of the academicians, who are thought to have a higher assumption of experiencing the blended teaching method, regarding the use of the blended method at the higher education level during the Covid-19 pandemic. In this study, a mixed research methodology was adopted in which quantitative and qualitative data were used together by using a convenient sampling method. In this context, the data collection tool was shared with the academicians via the LinkedIn network. 58 academicians from 16 universities participated in the research. Descriptive statistics (frequency, percentage and mean) were used in the analysis of Likert-type quantitative questions, and content analysis was used in the analysis of qualitative data. According to the findings of the study, academics who stated that they could possibly teach with the blended method in the future stated that their educational experience in blended courses was better than in face-to-face courses without any web component. On the other hand, academics mostly stated that the amount of interaction in blended courses is lower than in face-to-face courses. Together with these findings, it is understood that academicians perceive the quality of interaction in blended courses as similar to the quality of interaction in face-to-face courses. According to academics, the most positive aspects of using the blended method in lessons are the use of <em>technological opportunities, flexibility of space, flexibility of time and equality of opportunity.</em> The most negative aspects of using the blended method are attendance problems, <em>lack of communication, infrastructure problems and technological inadequacies and workload</em>. It is understood that the materials, tools or technologies that academicians use most in blended courses are <em>need-oriented trainings (web 2.0, web, innovation, technique, etc.), video and audio peripherals, online content, virtual reality technology and a powerful computer. </em>Although some of the academicians stated that their experiences in blended courses affected their face-to-face courses, almost half of them stated that their blended course experiences did not affect their face-to-face courses. These results may guide both present and future policies and procedures for blended learning in general.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0336/a.php" alt="Hit counter" /></p>
