HOTS (Higher Order Thinking Skill) is a thinking process of students at a higher cognitive level. The main goal of HOTS is to hone the thinking skills of students at a higher level, related to the ability to think critically, creatively, solve problems, and make decisions in complex situations. The student book on Christian Religious Education and Characteristics for SMP class VII published by the Ministry of Education and Culture, the 2017 revised edition is a book intended for students as a guide in learning activities. From the results of data analysis, it shows that HOTS content that appears most in textbooks is to analyze (C4) 46, 07% then create (C6) 33, 34% and the least evaluate (C5) 20, 58%. Therefore, the book is stated to follow the needs of junior high school students because it contains more cognitive abilities to analyze than other cognitive abilities. However, when viewed from the cognitive level, the book is not coherent because it produces (C6) more than evaluates (C5).

The problem of preserving historical memory in the context of modernity
Authors: Egorov Andrei 
Published: May 2023

Purposeful or thoughtless distortion of historical events, falsification of their causes, course or consequences, are fraught with such a transformation of the collective ideas of society and its citizens about their past, which carry the real prospect of the collapse of their internal integrity and stability. Respect for all pages of our own history is, of course, by no means the only one, but at the same time one of the important guarantees of the survival of modern Russian society.
The significance of historical memory to public consciousness and civic unity is hard to overstate. In this context, the resilience and vitality of, among other things, Russian society and its statehood depend to a large extent on citizens having an adequate understanding and decent attitude to the historical past of Russia and its peoples.
This circumstance implies the need for purposeful activities of state bodies, civil society institutions and, of course, professional historians to preserve historical memory on the basis of respect for the heroic past of their own country, based on documentary and other reliable historical facts, as well as objective scientific data, taking into account the basic spiritual and moral values of Russian society. It should be remembered that history invariably remains one of the significant resources of the state-organized people, the devaluation of which inevitably leads to the undermining of their vital cultural foundations and achievements.
It is necessary to state that history is indeed sometimes a field of fierce struggle, the reasons for which were obvious to Klyuchevsky, who said at one time that &quot;a people without history is like a child without parents: anyone can do with him what he pleases.&quot; Against the background of the contradictions of the modern multipolar world, there is a clear desire to reformat the historical past - including through falsification of history, which includes a deliberately inaccurate presentation or subjective interpretation of historical events vital to the world.
Bayesian pattern-mixture models for dropout and intermittently missing data in longitudinal data analysis
Authors: Blozis Shelley A. 
Published: May 2023

AbstractValid inference can be drawn from a random-effects model for repeated measures that are incomplete if whether the data are missing or not, known as missingness, is independent of the missing data. Data that are missing completely at random or missing at random are two data types for which missingness is ignorable. Given ignorable missingness, statistical inference can proceed without addressing the source of the missing data in the model. If the missingness is not ignorable, however, recommendations are to fit multiple models that represent different plausible explanations of the missing data. A popular choice in methods for evaluating nonignorable missingness is a random-effects pattern-mixture model that extends a random-effects model to include one or more between-subjects variables that represent fixed patterns of missing data. Generally straightforward to implement, a fixed pattern-mixture model is one among several options for assessing nonignorable missingness, and when it is used as the sole model to address nonignorable missingness, understanding the impact of missingness is greatly limited. This paper considers alternatives to a fixed pattern-mixture model for nonignorable missingness that are generally straightforward to fit and encourage researchers to give greater attention to the possible impact of nonignorable missingness in longitudinal data analysis. Patterns of both monotonic and non-monotonic (intermittently) missing data are addressed. Empirical longitudinal psychiatric data are used to illustrate the models. A small Monte Carlo data simulation study is presented to help illustrate the utility of such methods.
An Independent Determination of the Distance to Supernova SN 1987A by Means of the Light Echo AT 2019xis

Published: May 2023

Abstract
Accurate distance determination to astrophysical objects is essential for the understanding of their intrinsic brightness and size. The distance to SN 1987A has been previously measured by the expanding photosphere method and by using the angular size of the circumstellar rings with absolute sizes derived from light curves of narrow UV emission lines, with reported distances ranging from 46.77 to 55 kpc. In this study, we independently determined the distance to SN 1987A using photometry and imaging polarimetry observations of AT 2019xis, a light echo of SN 1987A, by adopting a radiative transfer model of the light echo developed in Ding et al. We obtained distances to SN 1987A in the range from 49.09 ± 2.16 kpc to 59.39 ± 3.27 kpc, depending on the interstellar polarization and extinction corrections, which are consistent with the literature values. This study demonstrates the potential of using light echoes as a tool for distance determination to astrophysical objects in the Milky Way, up to kiloparsec level scales.
Grandes manœuvres dans le Caucase du Sud
Authors: Minassian Gaïdz 
Published: May 2023

Si, lors de la chute de l’URSS en 1991, le leadership occidental a permis au Caucase du Sud de retrouver son statut de carrefour en impulsant une première phase du désenclavement, les rapports de forces ont aujourd’hui changé. Progressivement et à la faveur des conflits entre Russes et Géorgiens en 2008, puis entre Arméniens et Azerbaïdjanais en 2020, la Russie a retrouvé sa place dans cet isthme caucasien et au-delà. Au nom d’un monde post-occidental qu’elle cherche à édifier sur fond d’invasion de l’Ukraine, la Russie s’appuie entre autres sur le Caucase du Sud pour projeter les premières ébauches de son projet d’autonomie géopolitique. Mais cette ambition néo-impériale se heurte à l’Occident et aux intérêts de certaines puissantes émergentes comme l’Iran et l’Inde, qui, tout en coopérant avec la Russie, tiennent à ne pas se détourner de l’Occident pour dépendre totalement de Moscou.
L’Iran, la Russie et le Caucase : perspective géo-historique
Authors: Pahlavi Christian , Pahlavi Pierre 
Published: May 2023

S’élevant à une altitude moyenne de 4500 m, le Caucase forme une barrière granitique de 1200 kilomètres entre la mer Noire et la Caspienne séparant le sud-est de l’Europe de l’Asie. Creusée par le Tarek, l’antique Kavkaz est aussi un lien naturel entre l’Iran et la Russie qui, depuis plus de cinq siècles, rivalisent pour le contrôle de cette région charnière de l’ensemble eurasiatique. Combiner le recul historique et le prisme de la géopolitique est indispensable pour comprendre comment et dans quelle mesure le théâtre caucasien voit converger, en ce début de XXI e siècle, les intérêts stratégiques du Kremlin et ceux de la République islamique.
Le corridor Nord-Sud et la redéfinition des relations entre l’Iran, l’Arménie et l’Azerbaïdjan
Authors: Tisserand Zadig , Ciboulet Thomas 
Published: May 2023

Le développement du projet de « Corridor de Transit golfe Persique - mer Noire » marque un tournant dans la région, et cela dans un contexte géopolitique très instable depuis 2016, année des premières négociations. Il témoigne de la volonté iranienne de s’imposer comme un acteur incontournable dans le Caucase du Sud, mais aussi au-delà, tout en contournant la Turquie, rivale régionale de l’Iran et couloir traditionnel de transit entre le Moyen-Orient et l’Europe. Le « Corridor de Transit golfe Persique - mer Noire » fait d’autre part face à des difficultés liées aux gains qu’il pourrait occasionner pour les États participants. En effet, les opportunités de diversification d’approvisionnement énergétique et de désenclavement qu’il apporterait pour certains États sont considérées avec méfiance par les puissances régionales. L’Arménie, nœud de ce « Corridor de Transit golfe Persique - mer Noire », fait ainsi face aux attentes du voisin iranien ainsi qu’aux pressions de la Russie, surtout après la défaite militaire de 2020.
Retour sur le temps long du conflit du Karabagh
Authors: Mouradian Claire 
Published: May 2023

Après trois décennies d’une relative accalmie, le conflit du Karabagh dont la population à majorité arménienne réclame son rattachement à l’Arménie, est revenu à « la une » de l’actualité depuis septembre 2020, quand a débuté la ‘guerre de 44 jours’, désastreuse pour les Arméniens en nette infériorité numérique et matérielle, face à l’Azerbaïdjan, fort de sa manne pétrolière, du soutien actif de la Turquie et de mercenaires djihadistes et de la complicité passive russe. Les enjeux de ce conflit dépassent le cadre bilatéral et local et gagnent à être resitués dans un contexte post-colonial plus large de sortie de guerre (froide) et d’empire (soviétique), ainsi que dans une perspective de longue durée., Dans une zone de fractures multiples, la confrontation est en effet l’héritage d’un long passé – cinq siècles - de dominations, rivalités et pratiques administratives impériales, de violences de masse, d’interférences internationales.
AsPeer: Method to Self and Peer Assessment in Large Online Design Classes

Published: May 2023

Peer and self-assessment open opportunities to scale assessments in online classrooms. This article reports our experiences of using AsPeer- peer assessment system, with two iterations of a university online class. We observed that peer grades highly correlated with staff assigned grades. It was recorded that, the peer grade of all student submissions within the range of instructor grade averaged to 21.0% and that within the next 2 ranges was 49.0%. We performed three experiments to improve accuracy of peer grading. First, we observed grading bias and introduced a data driven feedback mechanism to inform peers of it. Students aided by feedback were mindful and performed grading with better accuracy. Second, we observed that the rubric lacked efficiency in translating intent to students. Simplified guiding questions improved accuracy in assessment by 89% of students. Third, we encouraged peers to provide personalized qualitative feedback along with rating. We provided them with feedback snippets that addressed common issues. 64% of students responded that the snippets helped them to critically look at submissions before rating.
De gemeentelijke administratieve sancties in Brussel op de proef gesteld tijdens de coronacrisis
Authors: Tatti Diletta 
Published: May 2023

Les mesures adoptées lors du premier confinement, de mars à juin 2020, ont été caractérisées par leur impact inédit sur la possibilité même de jouir de l’espace public. Des comportements jusqu’alors anodins ont été érigés en infractions. Dès le départ, la répression de ces dernières a constitué une priorité pour les autorités belges. En Région bruxelloise, les sanctions administratives communales (SAC) ont assuré ce rôle de répression, dans une articulation originale avec la répression pénale. À partir de l’analyse de données empiriques quantitatives et qualitatives, l’article se penche sur les contours et les applications de cette « exception bruxelloise », à l’aune d’enjeux liés à la jouissance de l’espace public dans une ville caractérisée par d’importantes inégalités sociospatiales.
A Study of Organophosphorus Induced Delayed Myelopathy: Uncommon Sequelae of a Common Poisoning
Authors: Porey Camelia , Jha Menka , Bhoi Sanjeev Kumar , Samal Priyanka , Naik Suprava 
Published: May 2023

Abstract

Introduction:
Organophosphorus (OP) compounds, with their lipophilicity, are responsible for a spectrum comprising of acute cholinergic symptoms, intermediate syndrome, as well as delayed neurological sequelae in the form of OP-induced delayed neuropathy and subsequently, myeloneuropathy with predominantly thoracic cord affection, manifested on partial recovery of the neuropathy. The pathogenesis of this myeloneuropathy in humans is still not well perceived.

Aim of Study:
To determine the onset and course of development of delayed myeloneuropathy in patients of OP poisoning.

Materials and Methods:
Twelve patients of OP ingestion presenting with delayed myeloneuropathy were evaluated with prior history, examination, MR imaging, nerve conduction and electromyography studies, and various evoked potentials to elicit the pattern of disease manifestation and progression.

Results:
Among the included patients, a majority had consumed chlorpyrifos and permethrin composition, a majority had undergone gastric lavage. Five (41.7%) had experienced acute worsening and 8 (66.7%) patients had developed intermediate syndrome. OPIDN had appeared after a median of 4 (1–8) weeks after the poisoning. All patients had lower limb hypertonia with wasting and distal more than proximal weakness with pure motor or sensorimotor involvement. MRI showed thoracic cord atrophy in 3 (25%) patients. Motor-evoked potential with reduced amplitude was noted in lower limbs on lumbar stimulation but absent on cortical stimulation.

Conclusion:
Various animal models have shown similar patterns of neurotoxicity in OP poisoning with predominant thoracic cord pathology. Further research in humans may be undertaken to elicit the pathogenesis, thereby improving the treatment modality.
