Des hommes forts mais dociles ? La salarisation du secteur de la sécurité locale comme révélateur de la hiérarchisation des masculinités à Lagos (Nigéria)
Authors: Revilla Lucie
Published: June 2022

Le secteur de la sécurité locale à Lagos fait figure de « cas-limite » pour penser les dynamiques de salarisation des services et remettre en cause les définitions normatives du salariat. En tâchant de ne pas amalgamer trop vite virilité et masculinité, cette contribution s’attache à décrire les pratiques de hiérarchisation des masculinités à l’œuvre dans le travail de sécurité à l’échelle locale. Si les expressions viriles et la force physique sont valorisées par les notables qui emploient des travailleurs de sécurité, elles justifient aussi l’assignation de certains hommes à une position subalterne. D’autres, en connotant leurs pratiques de travail d’une valeur morale et en les assimilant à la possession d’un savoir, obtiennent une meilleure rémunération. Enfin, la hiérarchisation des masculinités a des conséquences sur les recompositions du foyer des travailleurs de sécurité.
Labour, Incorporated: Dependent Contracting and Wageless Work in Africa’s “Responsible” Mines
Authors: Bolay Matthieu , Calvão Filipe
Published: June 2022

This article examines the growing corporate reliance on artisanal labour in the cobalt mines of the Democratic Republic of Congo. This shift from autonomous miners to corporate contractors, we suggest, holds historical significance and augurs a radical break with contemporary modes of extractive production. Under the banner of “responsible mining,” this form of dependent contracting fosters wageless relations in exchange for legal access to mining sites and corporate monopoly over artisanal production. By analysing the roots and mechanisms underlying these cooperative-corporate partnerships, we describe this emergent relation between labour and capital around three key features: the role of cooperatives as labour platforms, corporate control over local markets, and the deployment of discursive and technological regimes of responsibility and traceability.
Wage Labor and Social Inequality in Kinshasa’s Informal Economy: A Class Analysis
Authors: Mesa Héritier
Published: June 2022

This article explores the social trajectories of some “informal workers” and the dynamics of inequality they highlight. The study investigates how the structure of labor relations reveal class relations and unequal social positionalities more broadly within the informal economy. The research draws from ethnographic data collected about three forms of income-generating activities in Kinshasa: street bread, second-hand clothing, and urban agriculture. While access to capital offers some the opportunity to successfully develop a profitable income-generating activity, the limited access to various forms of capital constrains many to sell their labor power—often with weakened bargaining power—to those in possession of capital. Conversely, some actors have successfully overcome the constraint of the forms of asymmetric labor relations within the informal economy and secured a relatively decent living despite their precarious position.
Scolariser un élève en situation de handicap, la question de l'attention conjointe en classe
Authors: Vilaine Valérie
Published: June 2022

Nous nous intéressons à la scolarisation d’un élève avec trouble du spectre de l’autisme en classe de cours moyen première année (CM1), soutenu par une unité localisée pour l’inclusion scolaire (ULIS). L’étude concerne plus précisément la présence de cet élève dans la création et la réalisation d'une œuvre collective en danse. Nous cherchons à quelles conditions l’attention conjointe du professeur et des élèves au mouvement dansé ensemble permet d’augmenter la qualité de sa présence en danse. Notre recherche didactique s’inscrit dans une ingénierie coopérative entre enseignants et chercheure. Le collectif conçoit ainsi un coenseignement in situ afin de créer des situations didactiques favorables à la scolarisation. Nous décrivons le concret de la classe à partir d’épisodes sélectionnés dans des films d’étude. Les données d’observation sont travaillées à partir des notions de contrat et de milieu dans le cadre de la théorie de l’action conjointe en didactique (TACD).
Culturaliser les difficultés scolaires ? L’exemple des politiques éducatives en Picardie face aux classes populaires blanches
Authors: Ferhat Ismail
Published: June 2022

Sujet montant dans la littérature savante et administrative anglo-saxonne, les rapports de l’institution scolaire aux classes populaires blanches restent moins présents dans les sciences de l’éducation et de la formation françaises. L’article s’appuie sur les résultats d'une enquête collective et interdisciplinaire sur le territoire éducatif picard (intitulée « Preuve »). Elle souligne combien les politiques éducatives locales ont précocement culturalisé les difficultés éducatives qui pouvaient y exister. Sans nommer et viser explicitement les classes populaires blanches, elles ont contribué, des années 1960 aux années 2010, à en redéfinir le lien à l’école sous le signe du retard culturel. Celui-ci a fini par devenir un cadre prégnant des politiques éducatives locales, dont de nombreux choix (implantation d’établissement, financement, orientations stratégiques) étaient en partie reliés au caractère supposément « a-scolaire » ou « inapte » des jeunes issus de ce groupe social.
Efficacy and Tolerability of Erenumab for Prevention of Episodic Migraine in India
Authors: Chowdhury Debashish , Chaudhuri Jaydip R. , Ghosh Pahari , Kulkarni Rahul , Singh Sumit , Thakur Sneha , Thorat Anup V.
Published: June 2022

Background:

EMPOwER, a 12-week, double-blind (DB), randomized, placebo-controlled study evaluated the efficacy and safety of erenumab in adult patients with episodic migraine (EM) from Asia, the Middle East, and Latin America. This study analyzes the Indian experience for the use of erunumab for prevention of episodic migraine.

Objective:

The study aimed to evaluate the efficacy and tolerability of erenumab (70 mg and 140 mg) in EM patients from India.

Methods:

Randomized patients received monthly subcutaneous injections of placebo and erenumab 70 mg or 140 mg for 3 months. The primary endpoint was a change from the baseline in monthly migraine days (MMDs) at month 3. Other endpoints included achievement of ≥50%, ≥75%, and 100% reduction in MMD; a change in monthly acute migraine-specific medication treatment days; a change in patient-reported outcomes; and safety assessment.

Results:

Of the 539 patients screened, 351 patients were randomized (erenumab, 70 mg: n = 133 and 140 mg: n = 94; placebo: n = 124). The mean (±SD) age, disease duration, and MMD were 35.1 (±8.6) years, 6.77 (±6.01) years, and 7.82 (±2.89) days, respectively. The placebo-adjusted difference in mean MMD for erenumab 70 mg was -0.88 (95% CI, -2.16, 0.39; P = 0.174) days, and that for erenumab 140 mg was -1.01 (-2.42, 0.41; P = 0.164) days versus placebo. Secondary and exploratory endpoints demonstrated consistently better results in both erenumab dosage groups versus placebo. Treatment-emergent adverse events were comparable across groups (erenumab, 70 mg: 22.7% and 140 mg: 24.5%; placebo: 25.2%).

Conclusion:

Both doses of erenumab showed numerical improvement for efficacy endpoints and were well-tolerated in the Indian population. No new safety signals were reported.
On the monodromy conjecture for non-degenerate hypersurfaces
Authors: Esterov Alexander , Lemahieu Ann , Takeuchi Kiyoshi
Published: June 2022

The monodromy conjecture is an umbrella term for several conjectured relationships between poles of zeta functions, monodromy eigenvalues and roots of Bernstein–Sato polynomials in arithmetic geometry and singularity theory. Even the weakest of these relations – the Denef– Loeser conjecture on topological zeta functions – is open for surface singularities.

We prove it for a wide class of multidimensional singularities that are non-degenerate with respect to their Newton polyhedra, including all such singularities of functions of four variables.

A crucial difference from the known case of three variables is the existence of degenerate singularities arbitrarily close to a non-degenerate one. Thus, even aiming at the study of non-degenerate singularities, we have to go beyond this setting.

We develop new tools to deal with such multidimensional phenomena, and conjecture how the proof for non-degenerate singularities of arbitrarily many variables might look like.
Derivation of strain-gradient plasticity from a generalized Peierls–Nabarro model
Authors: Conti Sergio , Garroni Adriana , Müller Stefan
Published: June 2022

We derive strain-gradient plasticity from a nonlocal phase-field model of dislocations in a plane. After scaling, from the nonlocal elastic interaction we derive a continuous energy with linear growth depending on a measure which characterizes the macroscopic dislocation density as well as a nonlocal effective energy representing the far-field interaction between dislocations. Relaxation and formation of microstructures at intermediate scales are automatically incorporated in the limiting procedure based on

La transformation de la structure des États, le renoncement aux anciens fondements sociaux, politiques et culturels ont considérablement accéléré ou, dans certains cas, dévoilé des processus d’évolutions sous-jacents dans les langues de l’espace postcommuniste au tournant du XXIe siècle. C’est le lexique et la sémantique lexicale qui sont surtout concernés par ces modifications, mais on constate également des évolutions dans des domaines plus « protégés » : morphologie, syntaxe, phonétique, prosodie. Les chercheurs peuvent rarement observer une évolution aussi rapide se produire sous leurs yeux. Dans ce contexte, il est également intéressant d’analyser la perception par les locuteurs des variations et changements linguistiques ainsi que les efforts des États et des impositions étatiques pour modifier l’évolution naturelle d’une langue. Dans le présent volume, nous avons rassemblé des études de linguistes et d’anthropologues s’intéressant aux différentes langues des pays de l’espace postcommuniste : l’albanais, le bélarussien, le bulgare, les langues fenniques, le polonais, le russe, les langues sibériennes, le tchèque, le tchétchène, l’ukrainien. À travers ce numéro de Slovo, nous désirons offrir un terrain d’échanges pour les spécialistes de ces langues et cultures autour des variations et changements linguistiques.
Bilingualism in Chechnya in the 20th and 21st centuries
Authors: Guérin Françoise
Published: June 2022

Épisciences - Slovo

The unbalanced bilingualism we see in Chechnya clearly shows the hegemony of the Russian language over the Chechen language. However, the linguistic situation is not homogeneous in time or space. Indeed, while the older generations have a high level of competence in both languages, they consider the Chechen language as their mother tongue and the Russian language as a second language, whereas the opposite is true for the younger generations. The Chechen language skills of the younger generation are very low in urban areas and higher in rural areas.Thus, this article will focus, on the one hand, on the influence of the Chechen language in the use of Russian, manifesting itself notably at the phonological and syntactic levels. On the other hand, my research will focus on the penetration of Russian language within the Chechen language at the phonological, lexical and syntactic levels.

Le bilinguisme déséquilibré que nous constatons en Tchétchénie montre clairement l’hégémonie de la langue russe sur la langue tchétchène. Cependant, la situation linguistique n’est homogène ni dans le temps ni dans l’espace. En effet, si les générations plus âgées ont de larges compétences dans les deux langues, elles considèrent la langue tchétchène comme leur langue maternelle et la langue russe comme deuxième langue, alors que le contraire est vrai pour les générations plus jeunes. Les compétences en langue tchétchène de la jeune génération sont très faibles dans les zones urbaines et plus fortes dans les zones rurales.Ainsi, cet article se concentrera d’une part, sur l’influence de la langue tchétchène dans l’utilisation du russe, se manifestant notamment aux plans phonologique et syntaxique. D’autre part, mes recherches porteront sur la pénétration du russe au sein de la langue tchétchène aux niveaux phonologique, lexical et syntaxique.

Несбалансированное двуязычие, которое мы видим в Чечне, ясно показывает гегемонию русского языка над чеченским. Однако языковая ситуация не является однородной во времени или пространстве. Действительно, старшее поколение обладает широкими знаниями обоих языков, пи этом чеченский язык они считают своим родным, а русский – вторым, в то время как среди подрастающего поколения наблюдается обратная картина. Уровень владения чеченским языком молодым поколением в городской местности очень низкий, а в сельской – более высокий.

Od snu o funkční univerzálnosti k jazykovému liberalizmu. O standardizaci češtiny a debatách o spisovnosti na přelomu tisíciletí.

V průběhu 19. a v prvních desetiletích 20. století se čeští filologové aktivně podíleli na vytvoření kultivované varianty národního jazyka. Ve 30. letech 20. století Pražský lingvistický kroužek navrhl teorii spisovného jazyka a jazykové kultury založenou na fukčním kritériu, která se stala výchozím bodem uvažování o spisovné češtině až do dnešních dní. V 90. letech 20. století a na začátku nového tisíciletí někteří bohemisté označili takto vytvořenou spisovnou češtinu za vnucenou kodifikovanou formu, odporující každodennímu užívání jazyka, a nastínili nová řešení.

During the 19th and early 20th centuries, Czech philologists actively worked on the cultivated variant of the language. In the 1930s, the Prague Linguistic Circle proposed a theory of standard language and language culture, based on the functional criterion, which has become the basis of all reflection on Czech standard language till today. In the 1990s and 2000s, some bohemists considered the standard Czech thus conceived as an imposed code, in conflict with everyday uses, and sought to propose new solutions.

Sharivskyi Park (Kharkiv region, Ukraine): history and monitoring research during 1997–2018
Authors: Klymenko Yurii , Hryhorenko Alla
Published: June 2022

Changes in the taxonomic composition, landscapes, and plantations of the ancient Sharivskyi Park (Kharkiv region, Ukraine) were studied according to the literature and the results of our own monitoring research conducted in 1997 and 2016–2018. It was found that the number of species and cultivars decreased between the studies, but not significantly (the rate of decline in taxonomic diversity slowed down because due to a long period of inadequate care, only the most resistant species remained in the park). There was an almost complete loss of Picea abies plantations, which occupied 2.3 ha (7.9 % of the green area) in 1997. In most of Sharivskyi Park, the park landscape was replaced with a forest type. Garden and meadow landscapes are disappearing in the park. The Oak grove of Sharivsky Park, which represented the park type of the landscape, is degrading; it was replaced by derivative plantations that form the forest type of landscape. Forest-type areas of the oak grove appeared to be stable; degradation does not occur in them. Restoration of the degraded oak grove is possible only if the existing derivative plantations are removed, which is currently prohibited by law (therefore, changes in legislation are required), and artificial planting of oaks.

Repensar la Escuela de Salamanca: Presentación de publicaciones recientes
Authors: Domingo Rafael
Published: June 2022

Esta recensión colectiva analiza cuatro importantes obras recientes publicadas en torno a la segunda escolástica española, y más específicamente sobre la Escuela de Salamanca. El autor defiende que la Escuela de Salamanca irradia todavía luz sobre cuestiones tan actuales como los derechos humanos, la igualdad de todos los seres humanos, la autonomía del poder civil, la existencia de una comunidad humana global y la necesidad de entendimiento entre los pueblos. En el estudio actual de la Escuela de Salamanca, sin embargo, se echa en falta una mayor coordinación internacional entre todas las iniciativas. Se debe seguir trabajando para superar ciertas barreras culturales, especialmente idiomáticas y para mejorar la capacidad de integrar las diversas perspectivas desde las que aproximarse a este movimiento cultural. La Escuela de Salamanca debe analizarse holónicamente, es decir, como parte y como todo: como una parte de un movimiento más amplio llamado escolasticismo, que promociona un método de estudio concreto, y como un todo autónomo que surge en Salamanca. Excluir cualquiera de los enfoques posibles, como insinúan algunos autores, más que conducir a la precisión intelectual, supone una limitación del conocimiento. La unidad de la realidad demanda unidad en el saber.
Security Model for Randomization-based Protected Caches
Authors: Ribes-González Jordi , Farràs Oriol , Hernández Carles , Kostalabros Vatistas , Moretó Miquel
Published: June 2022

Cache side-channel attacks allow adversaries to learn sensitive information about co-running processes by using only access latency measures and cache contention.This vulnerability has been shown to lead to several microarchitectural attacks. As a promising solution, recent work proposes Randomization-based Protected Caches (RPCs). RPCs randomize cache addresses, changing keys periodically so as to avoid long-term leakage. Unfortunately, recent attacks have called the security of state-of-the-art RPCs into question.In this work, we tackle the problem of formally defining and analyzing the security properties of RPCs. We first give security definitions against access-based cache sidechannel attacks that capture security against known attacks such as Prime+Probe and Evict+Probe. Then, using these definitions, we obtain results that allow to guarantee security by adequately choosing the rekeying period, the key generation algorithm and the cache randomizer, thus providing security proofs for RPCs under certain assumptions.
The Best of Two Worlds: Deep Learning-assisted Template Attack
Authors: Wu Lichao , Perin Guilherme , Picek Stjepan
Published: June 2022

In the last decade, machine learning-based side-channel attacks have become a standard option when investigating profiling side-channel attacks. At the same time, the previous state-of-the-art technique, template attack, started losing its importance and was more considered a baseline to compare against. As such, most of the results reported that machine learning (and especially deep learning) could significantly outperform the template attack. Nevertheless, the template attack still has certain advantages even compared to deep learning. The most significant one is that it has only a few hyperparameters to tune, making it easier to use.We take another look at the template attack, and we devise a feature engineering phase allowing the template attack to compete or even outperform state-of-the-art deep learning-based side-channel attacks. More precisely, with a novel distance metric customized for side-channel analysis, we show how a deep learning technique called similarity learning can be used to find highly efficient embeddings of input data with one-epoch training, which can then be fed into the template attack resulting in powerful attacks
Complete and Improved FPGA Implementation of Classic McEliece
Authors: Chen Po-Jen , Chou Tung , Deshpande Sanjay , Lahr Norman , Niederhagen Ruben , Szefer Jakub , Wang Wen
Published: June 2022

We present the first specification-compliant constant-time FPGA implementation of the Classic McEliece cryptosystem from the third-round of NIST’s Post-Quantum Cryptography standardization process. In particular, we present the first complete implementation including encapsulation and decapsulation modules as well as key generation with seed expansion. All the hardware modules are parametrizable, at compile time, with security level and performance parameters. As the most time consuming operation of Classic McEliece is the systemization of the public key matrix during key generation, we present and evaluate three new algorithms that can be used for systemization while complying with the specification: hybrid early-abort systemizer (HEA), single-pass early-abort systemizer (SPEA), and dual-pass earlyabort systemizer (DPEA). All of the designs outperform the prior systemizer designs for Classic McEliece by 2.2x to 2.6x in average runtime and by 1.7x to 2.4x in time-area efficiency. We show that our complete Classic McEliece design for example can perform key generation in 5.2 ms to 20 ms, encapsulation in 0.1 ms to 0.5 ms, and decapsulation in 0.7 ms to 1.5 ms for all security levels on an Xlilinx Artix 7 FPGA. The performance can be increased even further at the cost of resources by increasing the level of parallelization using the performance parameters of our design.

The present study aimed to investigate the acute influence of repeated sprint training (RST) protocol on neuromuscular performance, measured with countermovement jump (CMJ) and a 40m sprint test, at different moments - during and post training; and to check if the sprint decrement obtained throughout the RST protocol would be related to the acute decrement in CMJ. The sample was composed of 11 male university-level team-sport athletes (22.66±1.97 years, 75.68±7.84 kg, 1.78±2.06 m). After the familiarization process, the volunteers participated in the CMJ baseline test, RST training session, CMJ test during the RST training, CMJ test after RST training (2h, 24h and 48h). The minimal individual difference (MID) was used to identify actual individual changes in CMJ and sprint performance. Pearson’s correlation coefficient, with 95% percentile bootstrap confidence intervals, was used to identify the relationship between CMJ and sprint performance. The RST training protocol was able to induce real CMJ and sprint performance changes. The CMJ performance returned to initial values 24 and 48 hours after RST training. The sprint performance remained altered during the RST, which was expected. However, performance remained below MID at 2h, 24h and 48h after the training protocol. The performance at CMJ and sprint showed a positive and significant correlation. A multi-parameter approach should be adopted to monitor the status of neuromuscular fatigue.

Este estudo apresenta um relato de experiência sobre o trabalho desenvolvido com crianças participantes de um projeto de extensão universitária de judô, em Porto Alegre, durante a pandemia da COVID-19, no ano de 2020. A orientação recebida dos órgãos de saúde para o cumprimento do distanciamento social como medida para conter a propagação da COVID-19 impactou significativamente a rotina das pessoas, uma vez que ficaram afastadas de suas atividades presenciais. O objetivo do trabalho foi ofertar uma proposta de ensino on-line de judô que, além de trazer os aspectos técnicos da modalidade, contribuísse para promoção da saúde psicossocial dos participantes, reduzindo os impactos do isolamento social. A turma observada foi composta por 20 crianças de ambos os sexos, com idades entre 8 e 13 anos, praticantes de judô há pelo menos 1 ano. Elas tiveram aulas de judô com duração de 45 minutos cada, três vezes por semana, entre os meses de junho e dezembro, ministradas através da plataforma Google Meet. Além da adaptação ao treinamento dos aspectos técnicos, foram propostos também momentos de conversa em cada encontro. Foi observado que todos os participantes apresentaram comprometimento com as aulas, mantendo bom nível de assiduidade, bem como dedicação para o aprendizado técnico em um formato diferente ao qual estavam acostumados. A experiência permitiu constatar que a prática do judô, mesmo no formato on-line, é possível, e assim, foi possível contribuir para a manutenção da atividade física e do aprendizado técnico, bem como para a promoção da saúde psicossocial dos participantes.

O trabalho com conteúdo esportivo nas aulas de Educação Física não deve se restringir à execução de movimentos técnicos, mas contribuir no processo de formação da criticidade dos/as estudantes. Nesta perspectiva, a utilização de metodologias que tenham o potencial de estimular o protagonismo de todos/as os/as participantes deve ser valorizada. Assim, o objetivo da presente pesquisa foi analisar os processos educativos que emergiram da inserção da Metodologia Callejera na prática do Basquetebol durante aulas de Educação Física escolar para o Ensino Médio. Para a coleta de dados foram utilizados registros em diários de campo, produzidos a partir de uma intervenção realizada em uma escola pública da cidade de São Carlos, São Paulo, Brasil. A análise dos dados utilizou da Análise de Conteúdo, dando origem às categorias: A) A competição no Basquetebol Callejero; B) As relações de gênero nas aulas de Educação Física Escolar. Durante as vivências, questões de gênero foram bastante recorrentes nas falas dos/as alunos/as, principalmente estereótipos machistas reproduzidos por meninos e meninas, que se fazem presentes não só no ambiente escolar como também em nossa sociedade, assim como a competitividade excessiva, que também esteve presente em situações de jogo. A partir da reflexão e do diálogo proporcionados pela Metodologia Callejera, passou-se a considerar o respeito, a cooperação e a solidariedade na prática do Basquetebol.

The paper found that after a course of general cryotherapy, the degree of extinguishing tryptophan fluorescence with pyrene decreases in the plasma membranes of lymphocytes and platelets by approximately 35% and 50%, respectively, in relation to these indicators in the control group. Previously, it was shown that the main target of cryotherapy on blood cells is the lipid component of biomembranes. In particular, there is a transition of lipids to a more «liquid» state, which, in turn, to a certain extent affects the structure and function of proteins, as well as lipid-protein interactions. With shortterm exposure to ultra-low temperatures on the body, a system-wide change in the functioning of stress-realizing and adaptive mechanisms occurs. The mechanism of adaptation to ultra-low temperatures is associated with a change in the physicochemical state of the biological membranes of the cells of the body.

The ecocentric strategy of radiation protection involves the expansion of experimental bases of radiation-induced effects in representatives of biota. This paper presents the calculated values of LD50/60 for the terrestrial mollusk F. fruticum after acute irradiation. To conduct a laboratory experiment, the conditions for keeping animals close to their natural habitat were selected. At the same time the mortality of mollusks in the control group remained at zero during the entire experiment. The calculated method of probit analysis using the least squares method was used to determine the LD50/60 index for F. fruticum mollusk of different age groups. Based on calculations, the LD index is 50/60 for three age groups of land mollusks: 118.7 ± 62.2 Gy, 115.6 ±33.9 Gy and 141.4 ±26.3 Gy for the first, second and third age groups, respectively.
