Assessing Study Abroad: Rubric Shopping, Managerialism, and Audit Culture at the Neoliberal University
Authors: Barkin Gareth , Collins Lauren
Published: February 2023

This article investigates the increasing prominence of intercultural and global skills assessment in study abroad administration and pedagogy, and how it influences the practice of international education and the roles it plays in the administrative spaces of U.S. higher education. Drawing on a series of interviews with administrators, faculty leaders, and international programs staff, as well as the authors’ experience in international education, this essay explores the diverse functions served by assessment rubrics in real-world educational contexts. Drawing on the work of Shore (2008), Wright and Shore (2017), Doerr (2015, 2017), Slaughter (2014), and Slaughter et al. (2004), we first discuss the rise in popularity of quantitative assessment tools that purport to measure individuals’ and groups’ intercultural abilities, awareness, or “competence,” in the context of neoliberalization and “audit culture” in higher education. We then describe the results of our qualitative research, focusing on (1) the diverse relationships different faculty, staff, and administrators have to assessment rubrics and their implementation; (2) their importance in administrative decision making and accreditation processes; (3) their relationship to neoliberalization concerns in international education and its increasing professionalization; and (4) the role these rubrics can play in promoting intentional program design and pedagogy. We demonstrate that international programs stakeholders engage in what we call rubric shopping, in which they move between different assessment tools and implement them in different ways and toward different ends, for a variety of contrasting reasons. We argue that these rubrics’ power in administrative spaces comes from the reification of authored concepts like “global citizenship” and “intercultural competence,” along with the scientism of the tools themselves; this cultivates a fuzzy, variable perception of positivism that is juxtaposed to and undermined by the ongoing practice of rubric shopping, among other factors. Finally, we encourage study abroad practitioners maintain a degree of critical distance from the field of intercultural skills assessment, while recognizing its utility in advocating for particular outcomes and pedagogical interventions.
Macro Flow Dynamic Study of Wind Around a Gable Roof Building with Openings
Authors: - Rupam Deka , - Kalyan Kumar Das
Published: February 2023

Understanding the flow field developed in the proximity of a building due to the wind flow over it is a prerequisite for designing a building. The wind environment around buildings plays a pivotal role not only from the point of view of structural integrity but also impacts the ventilation performance, pedestrian comfort and dispersion of pollutants. With the emergence of the green building concept in the light of the sustainable living, modern buildings are equipped with various openings such as doors, windows and ventilators. These openings change the flow characteristics in and around the building remarkably and make the flow field much more complex. The current study seeks to improve the understanding of both the internal and external flow fields around the buildings with openings. In this work, an attempt has been made to investigate the influence of wind direction on the flow behavior of wind in and around gable roof buildings with six different opening configurations. Commercially available CFD software ANSYS-FLUENT is used for numerical simulations. The numerical simulations are carried out to solve the steady Reynolds Averaged Navier Stokes (RANS) equations. The results obtained from the numerical simulations are validated with the previously published experimental results, and a good agreement was observed.

Authors: Erawati Suci , Idamawati Nababan  , Anisa Ulfah
Published: February 2023

Background: Halitosis is a sign of dental and oral health problems. Halitosis is characterized by the presence of an unpleasant odor in the oral cavity. Halitosis is caused by many things, one of which is a result of impaired saliva production, which is caused by smoking. Online motorcycle taxi drivers are in a community that is very close to smoking. This study aimed to provide an overview of aspects of knowledge, attitudes, and behavior related to halitosis in online motorcycle taxi drivers in Sei Putih Tengah Sub District, Petisah District, Medan, Indonesia.

Methods: Descriptive observational study. A total of 36 research subjects, namely online motorcycle taxi drivers, participated in this study. Observation of knowledge, attitudes, and behavior refers to a questionnaire developed by the halitosis clinic at the University of Basel, Switzerland. Univariate analysis was carried out with the help of SPSS software.

Results: The majority of research subjects are independently aware of bad breath and experience similar complaints <1 year. The majority of research subjects felt bad breath after waking up in the morning. The majority of research subjects also stated that dentists were the choice for consultation regarding bad breath disorders. The majority of research subjects know the origin of bad breath, the source of bad breath, and know that smoking is the cause of bad breath. Most research subjects did not feel ashamed of other people even though they felt they had bad breath.

Conclusion: Knowledge and behavior related to halitosis are good, although attitudes related to halitosis are not good among online motorcycle taxi drivers in Sei Putih Tengah Sub District, Petisah District, Medan, Indonesia.

A recent experienced (2021-22) in the Faculty of Education of Málaga has been analysed and important conclusions have been drawn from results obtained.
A Critical Review on the Grounds for Subsequent Claim of Reassessment
Authors:   KOREAN SOCIETY OF TAX LAW, Lee Jeon Oh
Published: February 2023

It is desirable from the point of view of justice to get back the tax that has been filed and paid incorrectly, whether it is tax return or assessment. However, if the tax system is designed in such a way that any tax wrongly
paid can be refunded forever, regardless of the reason or any method, the tax legal relationship will be in an unstable state for a long time, undermining legal stability and putting an excessive burden on tax administration. Therefore, in order to receive various tax benefits under the tax law, not only the requirements set by the tax law must be met, but in many cases, procedural requirements such as reporting within a specified period are required. For the same purpose, an appeal period is set for contesting the validity of a tax disposition, and a period for exercising the right to claim for rectification is set. If so, it should be seen that the grounds for requesting a subsequent rectification can also be limited by law.
In light of the text and system of the law, the grounds for requesting subsequent rectification stipulated in Article 45-2 Paragraph 2 of the Framework Act on National Taxes and Article 25-2 of the Enforcement Decree of
the Framework Act on National Taxes should be regarded as enumerated.
Article 45-2, Paragraph 2, Subparagraph 5 of the Framework Act on National Taxes and Article 25-2, Subparagraph 4 of the Enforcement Decree of the Framework Act on National Taxes contain the expression ‘similar grounds’, but the meaning is ‘similar grounds to those listed above’. It doesn’t mean ‘every reason other than those listed above’. Nevertheless, Supreme Court precedents sometimes broadly interpret the grounds stipulated in the statute as illustrative, and sometimes narrowly interpret them as if they were restrictive, in determining the grounds for a subsequent request for rectification. Regarding the argument, the Supreme Court lacks a consistent standard, such as overcoming the limitations of the principle of affirming rights and obligations when interpreting broadly, and raising differences between civil and criminal judgments when interpreting narrowly.
In conclusion, although there is room for flexible interpretation of the current grounds for the request for rectification, it should be considered to be basically enumerative. Nevertheless, the attitude of forcibly fitting reasons that are not stipulated in the Framework Act on National Taxes to similar to those stipulated in the Act is judicial legislation close to law creation, not law interpretation. For example, it is the right direction to seek legislative improvement measures for issues that require taxpayer relief, such as the inability to collect debts due to the bankruptcy of debtors, changes in legal interpretation, and unconstitutional decisions.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has made a considerable global effect, posing notable challenges for clinicians, the pandemic becoming one of the most imperative international health emergencies lately. Among other more frequent manifestations, SARS-CoV-2 disease may also give rise to skeletal muscle involvement. Viral-induced skeletal muscle involvement is a potentially severe manifestation of COVID-19 (Coronavirus Disease 2019) and may be either acute, or in the context of “long-COVID”. The present review aimed to illustrate few aspects about pathomechanisms, clinical and paraclinical frames, and treatment options for SARS-CoV-2-induced muscle involvement. Notably, it has been stated that SARS-CoV-2 may have the ability to invade muscle myocytes directly, the disease having a variety of clinical manifestations, from myalgia and muscle weakness to rhabdomyolysis. Nevertheless, it is also important to take into account that most of patients with severe forms receiving mechanical ventilation for more than one week may have complications such as CIM (critical illness myopathy) and/or CIP (critical illness polyneuropathy) that may be clinically similar to SARS-CoV-2-induced myositis, yet may be differentiated paraclinically from it. Additionally, it was hypothesized that SARS-CoV-2 infection may constitute a trigger for autoimmune diseases such as polymyositis/ dermatomyositis. Presently, there are no diagnosis criteria and no specific therapeutic strategy for SARS-CoV-2-induced myositis.
First Detection of Radio Emission Associated with a Classical Cepheid
Authors: Matthews L. D. , Evans N. R. , Rupen M. P.
Published: February 2023

We report the detection of 15 GHz radio continuum emission associated with the classical Cepheid variable star δ Cephei (δ Cep) based on observations with the Karl G. Jansky Very Large Array. Our results constitute the first probable detection of radio continuum emission from a classical Cepheid. We observed the star at pulsation phase ϕ ≈ 0.43 (corresponding to the phase of maximum radius and minimum temperature) during three pulsation cycles in late 2018 and detected statistically significant emission (>5σ) during one of the three epochs. The observed radio emission appears to be variable at a ≳10% level on timescales of days to weeks. We also present an upper limit on the 10 GHz flux density at pulsation phase ϕ = 0.31 from an observation in 2014. We discuss possible mechanisms that may produce the observed 15 GHz emission, but cannot make a conclusive identification from the present data. The emission does not appear to be consistent with originating from a close-in, late-type dwarf companion, although this scenario cannot yet be strictly excluded. Previous X-ray observations have shown that δ Cep undergoes periodic increases in X-ray flux during pulsation phase ϕ ≈ 0.43. The lack of radio detection in two out of three observing epochs at ϕ ≈ 0.43 suggests that either the radio emission is not linked with a particular pulsation phase, or else that the strength of the generated radio emission in each pulsation cycle is variable.

We present the results of a new reverberation mapping campaign for the broad-line active galactic nucleus (AGN) in the edge-on spiral IC 4329A.

The time delay for Hβ is consistent with the predicted value from the relationship between AGN luminosity and broad-line region radius, after correction for the ∼2.4 mag of intrinsic extinction at 5100 Å.

Modeling of the full reverberation response of Hβ was able to provide only modest constraints on some parameters, but does exhibit agreement with the black hole mass and average time delay. The models also suggest that the AGN structure is misaligned by a large amount from the edge-on galaxy disk. This is consistent with expectations from the unified model of AGNs, in which broad emission lines are expected to be visible only for AGNs that are viewed at relatively face-on inclinations.

; every halo in the catalog is characterized by several properties such as position, mass, velocity, concentration, and maximum circular velocity. Our models, built to be permutationally, translationally, and rotationally invariant, do not impose a minimum scale on which to extract information and are able to infer the values of Ωm and σ
8 with a mean relative error of ∼6%, when using positions plus velocities and positions plus masses, respectively. More importantly, we find that our models are very robust: they can infer the value of Ωm and σ
8 when tested using halo catalogs from thousands of N-body simulations run with five different N-body codes: Abacus, CUBEP3M, Enzo, PKDGrav3, and Ramses. Surprisingly, the model trained to infer Ωm also works when tested on thousands of state-of-the-art CAMELS hydrodynamic simulations run with four different codes and subgrid physics implementations. Using halo properties such as concentration and maximum circular velocity allow our models to extract more information, at the expense of breaking the robustness of the models. This may happen because the different N-body codes are not converged on the relevant scales corresponding to these parameters.
Synchrotron Firehose Instability
Authors: Zhdankin Vladimir , Kunz Matthew W. , Uzdensky Dmitri A.
Published: February 2023

We demonstrate using linear theory and particle-in-cell (PIC) simulations that a synchrotron-cooling collisionless plasma acquires pressure anisotropy and, if the plasma beta is sufficiently high, becomes unstable to the firehose instability, in a process that we dub the synchrotron firehose instability (SFHI). The SFHI channels free energy from the pressure anisotropy of the radiating, relativistic electrons (and/or positrons) into small-amplitude, kinetic-scale, magnetic-field fluctuations, which pitch-angle scatter the particles and bring the plasma to a near-thermal state of marginal instability. The PIC simulations reveal a nonlinear cyclic evolution of firehose bursts interspersed by periods of stable cooling. We compare the SFHI for electron–positron and electron–ion plasmas. As a byproduct of the growing electron-firehose magnetic-field fluctuations, magnetized ions gain a pressure anisotropy opposite to that of the electrons. If these ions are relativistically hot, we find that they also experience cooling due to collisionless thermal coupling with the electrons, which we argue is mediated by a secondary ion-cyclotron instability. We suggest that the SFHI may be activated in a number of astrophysical scenarios, such as within ejecta from black hole accretion flows and relativistic jets, where the redistribution of energetic electrons from low to high pitch angles may cause transient bursts of radiation.
A Plausible Model for the Galactic Extended Red Emission: Graphene Exposed to Far-ultraviolet Light

Extended red emission (ERE) is a broad feature in the spectral region of 500–900 nm commonly observed in a wide range of circumstellar and interstellar environments. Although the observational constraints for ERE are well established, definitive identifications of the carriers and associated processes complying with these constraints remain unanswered. We report a plausible two-step model involving far-ultraviolet (UV)-irradiated single-layer graphene (SLG), considered as large polycyclic aromatic hydrocarbons, to meet these constraints and supported by laboratory experiments. The far-UV-treated SLG, producing structural defects and graphene quantum dots, showed photoluminescence excitation spectrum extending from the far-UV to UV–visible region, hence meeting the requirements of far-UV light and high photon conversion efficiency. Furthermore, a photoluminescence band shifted from ∼585 to ∼750 nm for high-dose-exposed SLG agrees with the observed redshift of the ERE band in regions under a greater far-UV radiation density.
Quasar Properties from the Sloan Digital Sky Survey. III. The Quasars Obtained by the SDSS-IV
Authors: Huang Wei-Rong , Chen Zhe-Geng , Chen Zhi-Fu , Li Xiao-Feng
Published: February 2023

This paper provides the compilations of properties of the quasars newly obtained by the Sloan Digital Sky Survey (SDSS) during the fourth stage (SDSS-IV). The catalog is available on the journal's website. We have measured the main properties of emission lines around C iv, Mg ii, Hβ, and Hα spectral regions. We estimate the quasar redshifts from our fits of narrow [O iii], broad Mg ii, and broad C iv emission lines and find that the best redshifts included in DR16Q are robust with respect to our measurements. Based on the broad C iv, Mg ii, Hβ, and/or Hα emission lines, we calculate the virial black hole mass with empirical relationships provided by previous works. Systematic biases are found among the different line-based mass estimators.

emission that suggests the presence of an accretion disk. The dark companion does not seem to be a white dwarf because of the lack of any observed dwarf nova outbursts in the long-term data archive, although a magnetic white dwarf cannot be excluded. Alternatively, we propose a scenario wherein the dark companion is a neutron star, but we have not detected radio pulsations or a single pulse from the system with the FAST (Five-hundred-meter Aperture Spherical radio Telescope), which hints at a radio-quiet compact object. If the dark companion is identified as a neutron star, it will be the nearest (∼118 pc) and lightest neutron star. Furthermore, kinematic analysis of the system’s orbit in the galaxy may suggest its supernova event is associated with the radionuclide 60Fe signal observed from deep-sea crusts. This radio-quiet and X-ray-dim nearby neutron star may resemble an XDINS (X-ray-dim isolated neutron star) but in a binary.

We report a statistically significant detection of nongravitational acceleration on the subkilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences favorable observing apparitions every 5 yr. Thus, since its discovery, 2003 RM has been extensively tracked with ground-based optical facilities in 2003, 2008, 2013, and 2018. We find that the observed plane-of-sky positions cannot be explained with a purely gravity-driven trajectory. Including a transverse nongravitational acceleration allows us to match all observational data, but its magnitude is inconsistent with perturbations typical of asteroids such as the Yarkovsky effect or solar radiation pressure. After ruling out that the orbital deviations are due to a close approach or collision with another asteroid, we hypothesize that this anomalous acceleration is caused by unseen cometary outgassing. A detailed search for evidence of cometary activity with archival and deep observations from the Panoramic Survey Telescope and Rapid Response System and the Very Large Telescope does not reveal any detectable dust production. However, the best-fitting H2O sublimation model allows for brightening due to activity consistent with the scatter of the data. We estimate the production rate required for H2O outgassing to power the acceleration and find that, assuming a diameter of 300 m, 2003 RM would require Q(H2O) ∼ 1023 molec s−1 at perihelion. We investigate the recent dynamical history of 2003 RM and find that the object most likely originated in the mid-to-outer main belt (∼86% probability) as opposed to from the Jupiter-family comet region (∼11% probability). Further observations, especially in the infrared, could shed light on the nature of this anomalous acceleration.
Fomitiporella crystallina sp. nov. (Basidiomycota, Hymenochaetales) from China
Authors: Ji Xiao-Hong , Fan Longfei
Published: February 2023

Fomitiporella is an important genus of wood-decaying fungi. Many new species were revealed in the last five years, based on morphological characters and molecular data. During a study on the taxonomy of Fomitiporella, two specimens from China were investigated, which have morphological characteristics close to Fomitiporella. After morphological examinations and phylogenetic analyses, a new species was confirmed to be a member of the Fomitiporella clade.

Fomitiporella crystallina sp. nov. is described and illustrated as a new species, based on morphological characters and molecular evidence. It has perennial, irregular, pileate basidiocarps, an indistinct subiculum (ultrathin to almost lacking), lack of any kind of setae, has brownish, thick-walled basidiospores and causes a white rot. A molecular study, based on the combined ITS (internal transcribed spacer region) and nrLSU (the large nuclear ribosomal RNA subunit) dataset, supports the new species in Fomitiporella. The differences between the new species and phylogenetically related and morphologically similar species are discussed. A key to species with pileate to effused-reflexed basidiocarps of Fomitiporella is given.

To have an insight into the karyotype variation of eight Cucurbitaceae crops including Cucumis sativus Linnaeus, 1753, Cucumis melo Linnaeus, 1753, Citrullus lanatus (Thunberg, 1794) Matsumura et Nakai, 1916, Benincasa hispida (Thunberg, 1784) Cogniaux, 1881, Momordica charantia Linnaeus, 1753, Luffa cylindrica (Linnaeus, 1753) Roemer, 1846, Lagenaria siceraria var. hispida (Thunberg, 1783) Hara, 1948 and Cucurbita moschata Duchesne ex Poiret, 1819, well morphologically differentiated mitotic metaphase chromosomes were prepared using the enzymatic maceration and flame-drying method, and the chromosomal distribution of heterochromatin and 18S-5.8S-26S rRNA genes (45S rDNA) was investigated using sequential combined PI and DAPI (CPD) staining and fluorescence in situ hybridization (FISH) with 45S rDNA probe. Detailed karyotypes were established using the dataset of chromosome measurements, fluorochrome bands and rDNA FISH signals. Four karyotype asymmetry indices, CVCI, CVCL, MCA and Stebbins’ category, were measured to elucidate the karyological relationships among species. All the species studied had symmetrical karyotypes composed of metacentric and submetacentric or only metacentric chromosomes, but their karyotype structure can be discriminated by the scatter plot of MCA vs. CVCL. The karyological relationships among these species revealed by PCoA based on x, 2n, TCL, MCA, CVCL and CVCI was basically in agreement with the phylogenetic relationships revealed by DNA sequences. CPD staining revealed all 45S rDNA sites in all species, (peri)centromeric GC-rich heterochromatin in C. sativus, C. melo, C. lanatus, M. charantia and L. cylindrica, terminal GC-rich heterochromatin in C. sativus. DAPI counterstaining after FISH revealed pericentromeric DAPI+ heterochromatin in C. moschata. rDNA FISH detected two 45S loci in five species and five 45S loci in three species. Among these 45S loci, most were located at the terminals of chromosome arms, and a few in the proximal regions. In C. sativus, individual chromosomes can be precisely distinguished by the CPD band and 45S rDNA signal patterns, providing an easy method for chromosome identification of cucumber. The genome differentiation among these species was discussed in terms of genome size, heterochromatin, 45S rDNA site, and karyotype asymmetry based on the data of this study and previous reports.

Authors: Pelletier Liliane
Published: February 2023

Dans le contexte de l’école inclusive, il est recommandé de travailler en équipe. Or, la forme scolaire reste structurée par des frontières visibles et invisibles (Pelletier et Thomazet, 2019). L’étude porte sur la classe passerelle, dispositif situé au carrefour de plusieurs métiers avec la participation des parents en classe. À partir de photos et d’entretiens d’autoconfrontation simples, nous cherchons à éclairer le processus de collaboration dans ce territoire partagé et à repérer le rôle des objets frontières. Les résultats permettent de caractériser d’une part, l’activité collective en confortant le rôle structurant du leadership de l’enseignant (Bardy  et al. , 2019) et d’autre part, des objets frontières facilitant la dynamique collaborative entre famille et école : débriefing/briefing, espace-parents en classe, ateliers parentaux et activités pédagogiques coanimées.
Effet du temps d’exposition aux écrans sur le graphisme des enfants de 5 à 6 ans
Authors: André Alexandre , Cochetel Odile
Published: February 2023

Une étude épidémiologique transversale a été menée en 2019-2020 dans sept classes de grande section de maternelle en Auvergne. Le critère de jugement principal regroupe trois activités graphiques étalonnées, réalisées lors d’un bilan individuel à l’école. Le temps hebdomadaire d’exposition aux écrans de l’enfant a été évalué lors d’un entretien parental. 127 enfants ont été inclus. Les résultats montrent que les enfants passant plus de 10 heures en semaine d’école (plus de 20 heures en semaine de vacances scolaires) sur écran, quelle que soit leur origine sociale ou géographique ont des habiletés graphiques significativement plus faibles. D’autres travaux seront nécessaires pour explorer ce lien. Des programmes d’éducation en santé dans le milieu scolaire, sanitaire, et auprès des parents, seraient utiles afin d’améliorer l’usage des écrans et prévenir les troubles d’apprentissage.
Un malentendu qui dure : l’immigration et le communautarisme
Authors: Bastenier Albert
Published: February 2023

Un malentendu durable plane sur l’idée d’un communautarisme des immigrés qui constituerait un obstacle à leur intégration. Il repose en fait sur un obscurcissement et même une fétichisation de la notion de communauté. C’est elle qui demande à être clarifiée si l’on veut contribuer à plus de sérénité dans les politiques migratoires en Europe.
Les conséquences de la sortie de la Russie du Conseil de l’Europe
Authors: Costa Jean-Paul
Published: February 2023

À la suite de l’offensive militaire de la Russie contre l’Ukraine, le 24 février 2022, la Fédération de Russie a été aussitôt exclue du Conseil de l’Europe et a cessé d’être partie à la Convention européenne des droits de l’homme. Avant d’examiner les conséquences possibles de cet événement considérable, il faut rappeler les relations tumultueuses entre cet État et le Conseil et la Cour et décrire le processus complexe qui a conduit à la sortie de la Russie du système européen de protection des droits et libertés.
Chronique de jurisprudence du Comité européen des droits sociaux (2012-2022)
Authors: Marguénaud Jean-Pierre , Carillon Alain
Published: February 2023

Les premières décisions rendues par le Comité européen des droits sociaux en application du système de réclamations collectives instauré en 1995 lui ont valu une chronique dans cette Revue jusqu’en 2012. Depuis cette date, il a développé une jurisprudence trop méconnue, mais pourtant d’une importance considérable, qui justifie qu’une lumière particulière soit à nouveau portée sur ses décisions. Cette jurisprudence, construite patiemment à l’ombre de celle de la Cour européenne des droits de l’homme dont elle emprunte de nombreux mécanismes, révèle à la fois l’autonomie dont le Comité sait faire preuve pour adapter les concepts à la spécificité de la Charte sociale européenne et l’audace qu’il montre lorsqu’il s’agit d’en assurer l’effectivité ou d’aborder des contentieux politiquement sensibles tels que celui des barèmes d’indemnisation des licenciements. Doté d’une procédure et de méthodes d’interprétation parvenant à maturité, le Comité embrasse un domaine très vaste, allant des droits à caractère professionnel (rémunération, interdiction des discriminations, droit à la négociation collective, liberté syndicale et droit de grève) aux droits à caractère extraprofessionnel (protection des populations vulnérables, protection sociale, interruption volontaire de grossesse) en passant par le droit de l’environnement, dans lequel il peut faire figure de pionnier.
Accès à des documents classifiés, sécurité nationale et recherche historique : le secret d’État en équilibre(s)
Authors: Rosoux Géraldine
Published: February 2023

Appliquant, à l’égard de documents classifiés, les principes établis par l’arrêt de Grande Chambre Magyar Helsinki Bizottság concernant l’accès à l’information d’intérêt public, l’arrêt Šeks de la Cour européenne des droits de l’homme avalise le point d’équilibre – dont le secret constitue l’enjeu – dégagé par les autorités nationales croates. Du point de vue matériel, cette affaire illustre la mise en balance de deux intérêts bénéficiant d’un haut degré de protection dans le droit de la Convention : d’une part, la sécurité nationale et, d’autre part, la recherche historique. Du point de vue procédural, une procédure nationale contradictoire doit permettre de contester le refus d’accès, pour un motif lié à la sécurité nationale, même si l’exigence de motivation du refus se révèle atténuée.
L’enregistrement du nouveau sexe de la personne transgenre
Authors: Gallus Nicole
Published: February 2023

Selon la Cour européenne des droits de l’homme, la reconnaissance de la conversion sexuelle de la personne transgenre par une annotation en marge de son acte de naissance et non pas par l’établissement d’un nouvel acte ne constitue pas une violation des articles 8 et 14 de la Convention européenne des droits de l’homme. En effet, cette modalité réalise un juste équilibre entre le droit au respect de la vie privée de la personne concernée et les exigences de sécurité publique de l’enregistrement de l’état civil.
La Cour de Strasbourg remet en cause tout le système belge de reconnaissance des cultes
Authors: Wattier Stéphanie
Published: February 2023

Saisie afin de se prononcer sur une ordonnance qui impacte le régime fiscal des communautés religieuses non reconnues en Région bruxelloise, la Cour européenne des droits de l’homme a été amenée, en cascade, à remettre en cause tout le système de reconnaissance des cultes tel qu’il existe actuellement en Belgique.
Politisation du voile et mobilisation des accompagnatrices scolaires contre la circulaire Chatel
Authors: Hadj Belgacem Samir , Karimi Hanane
Published: February 2023

Cet article s’intéresse aux conditions d’émergence et de déploiement d’une mobilisation collective de mères portant le foulard contre la circulaire Chatel qui interdit le port de signes religieux aux parents accompagnateurs lors de sorties scolaires. L’étude du collectif Sorties scolaires : avec nous ! (2012-2015) permet d’observer la construction d’une cause dans un cadre fortement contraint où le foulard des accompagnatrices scolaires est désigné comme une atteinte à la laïcité. Les mères accompagnatrices se mobilisent contre leur exclusion par une campagne d’interpellation des autorités scolaires et politiques au plan local et national et par une demande d’égalité de traitement et de citoyenneté. Ce cadrage tend à contourner la mise en cause de visibilité religieuse musulmane (hijab) par la circulaire Chatel qui devient l’objet d’un dissensus dans la lutte contre l’islamophobie.
Atomistic modeling and molecular dynamic simulation of polymer nanocomposites for thermal and mechanical property characterization: A review
Authors: Shahapure Nilesh , Shinde Dattaji , Kelkar Ajit
Published: February 2023

Epoxy resins are formed when epoxy monomers react with crosslinkers that have active hydrogen sites on them such as amine and anhydrides. These cross-linked structures are highly unpredictable and depend on different parameters during curing. Epoxy material when reinforced with nanoparticles has got importance because of its extraordinary enhanced mechanical and thermal properties for structural application. Experimentally it is challenging to tailor these nanostructures and manufacture epoxy-based nanocomposites with desired properties. An experimental approach to preparing these is tedious and costly. The improvement of such materials requires huge experimentation and a better level of control of their properties can't be accomplished up till now. There is a need for numerical experimentation to guide these experimental procedures. With the headway of computational techniques, an alternative for these experiments had given an effective method to characterize these nanocomposites and study their reaction kinetics. Molecular dynamics (MD) simulation is one such technique that works on density function theory and Newton*s second law to characterize these materials with different permutations and combinations during their curing. This review is carried out for MD simulation studies done to date on different epoxies and epoxy-based nanocomposites for their thermal, mechanical, and thermo-mechanical characterization.
The singularity of two kinds of tricyclic graphs
Authors: Ma Haicheng , You Xiaojie , Li Shuli
Published: February 2023

Let $ G $ be a finite simple graph and let $ A(G) $ be its adjacency matrix. Then $ G $ is $ singular $ if $ A(G) $ is singular. Suppose $ P_{b_{1}}, P_{b_{2}}, P_{b_{3}} $ are three paths with disjoint vertices, where $ b_i\geq 2 (i = 1, 2, 3) $, and at most one of them is 2. Coalescing together one of the two end vertices of each of the three paths, and coalescing together the other end vertex of each of the three paths, the resulting graph is called the $ \theta $-graph, denoted by $ \theta(b_{1}, b_{2}, b_{3}) $. Let $ \alpha(a, b_{1}, b_{2}, b_{3}, s) $ be the graph obtained by merging one end of the path $ P_{s} $ with one vertex of a cycle $ C_{a} $, and merging the other end of the path $ P_{s} $ with one vertex of $ \theta(b_{1}, b_{2}, b_{3}) $ of degree 3. If $ s = 1 $, denote $ \beta(a, b_{1}, b_{2}, b_{3}) = \alpha(a, b_{1}, b_{2}, b_{3}, 1) $. In this paper, we give the necessity and sufficiency condition for the singularity of $ \alpha(a, b_{1}, b_{2}, b_{3}, s) $ and $ \beta(a, b_{1}, b_{2}, b_{3}) $, and we also prove that the probability that any given $ \alpha(a, b_{1}, b_{2}, b_{3}, s) $ is a singular graph is equal to $ \frac{35}{64} $, the probability that any given $ \beta(a, b_{1}, b_{2}, b_{3}) $ is a singular graph is equal to $ \frac{9}{16} $. From our main results we can conclude that such a $ \alpha(a, b_{1}, b_{2}, b_{3}, s) $ graph ($ \beta(a, b_{1}, b_{2}, b_{3}) $ graph) is singular if $ 4|a $ or three $ b_i (i = 1, 2, 3) $ are all odd numbers or exactly two of the three $ b_i (i = 1, 2, 3) $ are odd numbers and the length of the cycle formed by the two odd paths in $ \alpha(a, b_{1}, b_{2}, b_{3}, s) $ graph ($ \beta(a, b_{1}, b_{2}, b_{3}) $ graph) is a multiple of 4. The theoretical probability of these graphs being singular is more than half.
Biodegradable waste to renewable energy conversion under a sustainable energy supply chain management
Authors: Sarkar Mitali , Seo Yong Won
Published: February 2023

Effective surveillance during smart cities' sustainable development allows their cleanliness to be maintained by reusing waste to produce renewable energy. This study quantifies the biodegradable waste generated in specific regions of several cities and presents ways to convert it into renewable energy. This energy can then be used to partially support regional energy demands. This study explores ways of reducing carbon emissions for biodegradable waste collection processes in regional centers, ultimately sending the biodegradable waste to the energy conversion center. The smart production system allows for the flexible production and autonomation of rates of conversion; green technology depends on each regional center's research management, which is a decision variable for reducing carbon emissions. The major contribution of this study is to consider an energy supply chain management with flexibility of energy conversion under the reduction of carbon emissions, which leads to a sustainable ESCM with the global maximum profit. This study uses mathematical modeling to decrease biodegradable waste with conversion of energy through a classical optimization technique. The solution to this mathematical model yielded significant results, providing insight into waste reduction, reduced carbon emissions and the conversion of biodegradable waste to energy. The model is examined using numerical experiments, and its conclusion supports the model with the fundamental assumptions. Results of sensitivity analysis provide insight into the reduction and re-utilization of wastes, carbon emission reduction, and the benefits of using renewable energy.
