Authors: Stesko A. V.
Published: December 2022

The aim: Investigation of the survival rate of the red king crab during trawl fishing under the conditions of a research survey.   The methods: The paper based on works which were completed in 2020–2021 through the trawl survey in the Barents Sea. King crabs were overexposed on the open deck of the research vessel and after that they were keeped in traps and dropped out in the sea water of 15 m depth and keeped there more than 1.5 hours. Crabs heath conditions were checked after the experiments. We also used data on the state of the environment in the area of work and data on the number of injured individuals in the catches.   The newness: This is a first comlex research of king crabs survivability on the Barents Sea during the trawl catch. The same works were provided on the Barents Sea through traps.   The results: On an open deck at an air temperature of 3 to 12 °C and overexposure of less than 3 hours, the mortality of crabs was extremely low, amounting to a maximum of 2.5 % of the number of individuals in the experiment. Over the next 3–5 hours, up to 40 % of crabs could die, and if overexposed for more than 5 hours, up to 59 %. The average proportion of dead crabs during overexposure of 3–5 hours was 5.4 ± 0.3 %, more than 5 hours — 23.4 ± 1.2 % and increased with increasing air temperature: under conditions above 10 °C 100 % survival were never seen. The average delayed mortality in the simulation of release of crabs into the sea was 11 percent.   The practical significance: The results could be used for improving of fishery rules on the North fishery basign and red king crabs stock assessement. The article is not intended to calculate possible damage based on the results of control activities.

The aim of this research was to assess the scale and determine the possible reasons of the death of Caspian seals (Pusa caspica), that were washed up by a storm on the coast of the Republic of Dagestan in early December 2020. The corpses of seals were found on the Dagestan coast from the mouth of the Terek River to the southern outskirts of Derbent, in total about 205 km long.   The main methods of collecting material were: accounting of dead seals in open (not overgrown with vegetation) coastal areas, measurements and pathoanatomic autopsies of corpses, sampling of internal organs and tissues of animals for histological, virological, helminthological and toxicological studies. Simultaneously with the onshore work, observations of seals and registration of hydro- meteorological parameters in the coastal waters of the Republic of Dagestan were carried out by two research vessels of the Caspian branch of the Federal Research Institute for Fishery and Oceanography («KaspNIRH»): «Caspian Explorer» and «Hydrobiologist».

   As a result, 12 coastal sites with a total length of 49.2 km were surveyed, where 313 corpses of dead seals were registered; the average density was 12.27 ± 2.16 specimens/km. The total number of dead seals in December 2020 was estimated at 2,515 ± 443 individuals. Adult females predominated among the dead animals, most of which were pregnant. The corpses showed no signs of infectious diseases or exhaustion. Judging by their condition, the death of animals occurred during the first two decades of November, at some distance from the shore.   Conclusion: Basing on the data collected, infectious diseases, helminthiasis, intoxication, accident by catch in the fishing gears, and the impact of an underwater shock wave were excluded from the possible reasons of the death of seals. Acute asphyxia as a result of local release of natural gas, which could form above the sea surface a polluted lens of air unsuitable for breathing, was recognized as the most likely cause of the seals death.

Published: December 2022

The purpose of the workis to review the history of the development of walleye pollock stocks in the of Okhotsk sea, to analyze the fishery and the state of its stocks.

Methods:literature data, materials of long-term surveys by VNIRO (1997–2002) on the walleye pollock spawning grounds of Western Kamchatka, as well as the R/V «Professor Kaganovsky» in the spring of 2022 were used. Fishery statistics of OSM Monitoring.

Results:The maximum walleye pollock catch (0.91 million tons) in the North Sea of Okhotsk subarea was achieved in 1995. In the period 1998–2001 annual catches averaged 510 thousand tons, in 2002–2008 decreased to 210 thousand tons. Over the past decade, there has been a gradual increase in catch from 286 thousand tons in 2009 to 383 thousand tons in 2020. Pollock catches in the West Kamchatka and Kamchatka-K uril subzones after high fishery rates achieved in 1996–1997 (1.2 million tons), began to decline, falling in 2004 to 191 thousand tons, after which a tendency to their increase appeared. In the period 2016–2019 catches walleye pollock of East Okhotsk sea stabilized at the level of 617–618 thousand tons, in 2020 the catch amounted to 681 thousand tons. The walleye pollock stock in the East Sakhalin subzone is currently at a low level, its gradual recovery began in the mid-2000s in 2019–2020. its catch was 110 thousand tons.

Novelty:New data on walleye pollock stocks in the Okhotsk Sea are presented. Based on the results of a trawl survey conducted in the spring of 2022, the total number of walleye pollock in the Okhotsk Sea was estimated at 56.043 billion ind., biomass —  13.497 million tons, while the commercial stock was estimated at 10.413 million tons and 21.964 billion ind. Maps of the distribution of adult walleye pollock and eggs in the Okhotsk Sea in the spring of 2022 are given.

Practical significance:data on the status of walleye pollock stocks in the Okhotsk Sea will be used to prepare TAC materials, as well as recommendations for rational fishery.
A Prototype For Quantum Database in Hybrid Quantum

Published: December 2022

This study proposes a prototype And a possibility to converge both classical database and fully quantum database. This study mostly identifies the gap between this classical database and quantum database and it proposes a hypothesis and prototype which can be implemented in future products. It is a way that can be used in future industrial product development on hybrid quantum computers. The existing concept used to consider oracle as a black box this study opens up the possibility for the quantum industry to develop the QASAM module so that we can develop a fully quantum database instead of using a classical database as BlackBox. As the Toffoli gate is basically an effective NAND gate it is possible to run any algorithm theoretically in quantum computers. So we will propose a logical design for memory management for the quantum database, security enhancement model, Quantum Recovery Manager & automatic storage management model and more for the quantum database which will ensure the quantum advantages. In this study, we will also explain the Quantum Vector Database as well as the possibility of improvement in duality quantum computing. It opens up a new scope, possibilities and research area in a new approach for quantum database and duality quantum computing.
How to Exploit Optimization Experience? Revisiting Evolutionary Sequential Transfer Optimization: Part A - Benchmark Problems
Authors: xue xiaoming , yang cuie , Feng Lianghuan , zhang kai , song linqi , Tan Kay Chen
Published: December 2022

Evolutionary sequential transfer optimization (ESTO), which attempts to enhance the evolutionary search of a target task using the knowledge captured from several previously-solved source tasks, has been receiving increasing research attention in recent years. Despite the tremendous approaches developed, it is worth noting that existing benchmark problems for ESTO are not well designed, as they are often simply extended from other benchmarks in which the relationships between the source and target tasks are not well analyzed. Consequently, the comparisons conducted on these problems are not systematic and can only provide numerical results without a deeper analysis of how an ESTO algorithm performs on problems with different properties. Taking this clue, this two-part paper revisits a large body of solution-based ESTO algorithms on a group of newly developed test problems, to help researchers and practitioners gain a deeper understanding of how to better exploit optimization experience towards enhanced optimization performance. Part A of the series designs a problem generator based on several newly defined concepts to generate benchmark problems with diverse properties, which are competitive in resembling real-world problems. Part B of the series empirically revisits various algorithms by answering five key research questions related to knowledge transfer. The results demonstrated that the performance of many ESTO algorithms is highly problem-dependent, which suggest the necessity of more research efforts on transferability measurement and enhancement in ESTO algorithm design. The source code of the benchmark suite developed in part A is available at https://github.com/XmingHsueh/Revisiting-S-ESTOs-PartA.
Version Age-Optimal Cached Status Updates in a Gossiping Network with Energy Harvesting Sensor
Authors: Delfani Erfan , Pappas Nikolaos
Published: December 2022

In this work, we consider a real-time IoT monitoring system in which an energy harvesting sensor with a finite-size battery measures a physical process and transmits the status updates to an aggregator. The aggregator, equipped with caching capabilities, can serve the external requests of a destination network with either a stored update or a fresh update from the sensor. We assume that the destination network act as a gossiping network in which the update packets are forwarded among the nodes in a randomized setting. We utilize the MDP framework to model and optimize the average Version Age of Information (AoI) of the network, and to obtain the optimal policy at the aggregator. The structure of the optimal policy is analytically demonstrated, and numerically verified. Numerical results further highlight the effect of the system parameters on the average Version AoI. The simulations reveal the superior performance of the optimal policy compared to a set of baseline policies.
Novel Hardware Accelerated Magnetic Field Calculation Approach for Circular Coils With Rectangular Cross Section
Authors: Dobrota Davor , Sočec Nikola , Vrabac Lara , Bojanjac Dario
Published: December 2022

In this paper, we present a performance-oriented approach for calculating magnetostatic fields produced by circular coils. Those include the magnetic vector potential, magnetic flux density and magnetic field gradient, together addressed as fields.

Many inductive elements used in a wide range of applications can be modeled as circular coils with a rectangular cross-section, and this is reflected in the number of papers on the subject. Instead of extensively utilising analytic methods, we focused on achieving maximum performance by efficiently implementing the Gauss-Legendre quadrature and applying it to expressions which are simple with respect to computational intensity. To properly leverage this, we implemented our approach in the C++ programming language. The CUDA framework enabled us to utilise the full power of Nvidia graphics cards, especially when multiple coils are present. Our approach can also be used from Python and MATLAB with a small performance penalty.

Performance of field compute methods is primarily expressed in the number of field values calculated every second. Processor performance was tested on multiple systems and exceeded one million points per second on all of them. Graphics card performance is particularly noteworthy, with over 5 million magnetic flux density values computed every second for a system of 100 coils, placing effective performance at more than 500 million points per second on a contemporary laptop graphics card.

The meticulous implementation, available on GitHub, and unique performance are the highlights of our work.

Published: December 2022

When it comes to the provision of medical services, quality is crucial. It entails changing healthcare so that actions, not just words, reflect values. Additionally, there is a change from quantity to quality. The outcome of treatment is more crucial than how many patients a doctor sees in a day. The standard of care can be raised by being aware of numerous internal and external factors. Organizational leadership and management must comprehend these elements and incorporate them into the provision of services. This cross-sectional research seeks to determine the critical internal variables needed to raise the caliber and effectiveness of healthcare services provided by Hafr Al Batin hospital. It sought to learn the healthcare team's perspectives on internal factors and how to steer patients toward the best results. In favors of the patients, Hafr Al Batin hospital's healthcare team surveyed 66 respondents. Twenty-one respondents believe that the healthcare team needs more education to raise the standard of care provided in hospitals. The best way to improve medical performance, in the opinion of 38, is through communication skills, which 34 people believe can be learned by attending expert lectures. According to 25 respondents, raising salaries is the most crucial step that can be taken to improve the standard of healthcare services. While 63 respondents agree that healthcare services and equipment are equally important, 3 respondents disagree. Improvements must be made to internal organizational factors and healthcare service quality to achieve improved performance. by increasing the healthcare team's knowledge through lectures from knowledgeable members, improving communication and leadership skills, using more cutting-edge equipment, and paying higher salaries to inspire employees.

Self-regulation, the ability to guide behavior according to one’s goals, plays an integral role in understanding loss of control over unwanted behaviors, for example in alcohol use disorder (AUD). Yet, experimental tasks that measure processes underlying self-regulation are not easy to deploy in contexts where such behaviors usually occur, namely outside the laboratory, and in clinical populations such as people with AUD. Moreover, lab-based tasks have been criticized for poor test–retest reliability and lack of construct validity. Smartphones can be used to deploy tasks in the field, but often require shorter versions of tasks, which may further decrease reliability. Here, we show that combining smartphone-based tasks with joint hierarchical modeling of longitudinal data can overcome at least some of these shortcomings. We test four short smartphone-based tasks outside the laboratory in a large sample (N = 488) of participants with AUD. Although task measures indeed have low reliability when data are analyzed traditionally by modeling each session separately, joint modeling of longitudinal data increases reliability to good and oftentimes excellent levels. We next test the measures’ construct validity and show that extracted latent factors are indeed in line with theoretical accounts of cognitive control and decision-making. Finally, we demonstrate that a resulting cognitive control factor relates to a real-life measure of drinking behavior and yields stronger correlations than single measures based on traditional analyses. Our findings demonstrate how short, smartphone-based task measures, when analyzed with joint hierarchical modeling and latent factor analysis, can overcome frequently reported shortcomings of experimental tasks.
Именная морфология в памятнике марийской письменности… «Начатки христианского учения...» (1839/1841). Падеж
Authors:   Ivannikov Institute for System Programming, RAS (Moscow), Klyucheva Maria ,   Vasilyev Mari Research Institute of Language, Literature and History (Yoshkar-Ola)
Published: December 2022

This article continues the analysis of the Mari text of the book “The Beginnings of Christian doctrine ...”, published in Kazan in 1841. Previously (see [Klyucheva 2021]), the verb morphology (conjugation) in it was described. This work describes the noun morphology in “The Beginnings…” — the case system of nouns in the singular. In continuation of this work, we plan to consider the categories of number and possession. The case system in “The Beginnings…” includes all the 9 cases of the modern standard Mari (Meadow-Eastern) language and also abessive and ablative. The presence of the causative (case) with the indicator -lanen is questionable: it occurs in “The Beginnings…” in a single example with a pronoun. The analysis of noun morphology in “The Beginnings…” is made in comparison with the standard Mari (Meadow-Eastern) language and Meadow dialects. Its specificity lies primarily at the phonetic level: in the vocalism of unstressed syllables and the stress system. The system of vowels includes labial reduced u and ü. They are expressed in “The Beginnings…” by the letters о, у, ю, and are located on the border between the stem and the case affix (after labial vowels in the stem). In the standard language, only the non-labial reduced vowel ǝ̂ occurs in this position. Such vowel harmony in the language of “The Beginnings…” corresponds to the western subdialects of the Meadow dialect, especially the Volga subdialect. As regards the stress system, in “The Beginnings…” in the comitative, dative, ablative, partly in the lativе the stress is kept on the same syllable as in the nominative, while in the literary norm and in modern Meadow dialects all these case suffixes are under stress (only in the dative is the stress fluctuation allowed). This indicates changes in the system of stresses in the Meadow dialect since the creation of the monument. The article also shows examples of non-standard use of case forms (mainly inessive, accusative and genitive). They may reflect some poorly studied functions of cases in Meadow dialects. The results of the study of the case correlate with the previously obtained conclusions about the Volga dialect as the dialectal basis of this written monument. It reflects not only the modern, but also the historical features of this dialect.
Изменение этноязыковой территории западных и южных манси в XVII—XX вв. Часть I. Предуралье и бассейн Туры

Published: December 2022

This article examines the changes in the ethno-linguistic territory of the Mansi (Voguls) in the Cis-Urals and in the Tura basin during the 17th—20th centuries. In most of these lands, the Mansi and Mansi languages disappeared no later than the early / middle 19th century. But the assimilation and displacement of the Mansi took place a little differently and at different speeds in different parts. The purpose of this article is to bring together and systematize information about the distribution of the Mansi and Mansi languages in the western and southern parts of their range during the 17th—20th centuries. Both primary sources of the 17th—19th centuries and the works of researchers of the 19th—21st centuries were used as material for the study. Particular attention is paid to census data, as well as data on yasak payers of the 17th century. The result of the work is a detailed reconstruction of the geographical distribution and demographics of the Mansi in this region after the 17th century. All toponyms mentioned in earlier works were georeferenced, and diachronic correlation of objects from different time layers was made. For convenience of presentation, the territory under consideration is divided into several sub-areas. Special attention was paid to the time of the disappearance of the Mansi languages in each sub-area and more accurate georeferencing of the known Mansi dictionaries of the 18th—19th centuries. The collected and systematized information is illustrated by detailed ethno-linguistic maps, which make it possible to compare the situation with the Mansi and the Mansi language in different centuries. Such an analysis, based on the areal principle and accompanied by detailed maps, is being done for the first time. The results of the work, including maps, can be used by specialists of various profiles, incl. linguists studying Mansi dialectology and toponymy, ethnographers and historians

This paper offers a comprehensive analysis of proximity between the dialects within Khanty and Mansi languages, which form the Ob-Ugric group within the Uralic languages. Even though they are thought to be closely related, research has shown the discrepancy between the phonological and lexicostatistical distance between Khanty varieties vs. Mansi varieties. In the article, innovations in phonology, morphology and basic vocabulary are brought together and compared. New data from archives (18th century) and latest fieldwork shed the light on chronology of phonetic, morphological and lexical changes. Using comparative method, it is shown that in the late 18th century Mansi dialects were still not very distant from each other. Moreover, phonetic differences which hindered mutual understanding between speakers of eastern and northern dialects in the 20th century became distinctive not earlier than 250 years ago. On the contrary, Khanty dialects were as distant as separate languages back in the late 18th century. Judging by glottochronological calculations, the time of divergence of contemporary Kazym and Vakh Khanty can be dated back as early as the beginning of the first millennium AD. These Khanty varieties have more differences than any Slavic and even Turkic (except Chuvash) languages between each other. Therefore, they should be counted as different languages, not dialects. Overall, from the extensive analysis of phonetics, morphology and basic vocabulary, it is proved that Mansi varieties were still dialects (until all but one became extinct) and Khanty varieties were separate languages when they were first recorded in the late 1700s.

State-resolved charge exchange (CX) cross sections are of the utmost importance for modeling related photon emissions existing in a broad range of astrophysical environments. With the cold-target recoil-ion momentum spectroscopy, we determined with high accuracy the state-resolved single and double CX cross sections at the quantum orbital angular momentum level for solar wind ion C4+ collisions with He in an energy range of 1.67–20 keV u−1, which allow one to benchmark the CX calculations in great detail, and to test the applicability of the analytical n- and ℓ-distribution models widely adopted by the astrophysical community. We found that the present measurements are well reproduced by the most recent state-of-the-art atomic–orbital close-coupling calculations. However, the CX models failed to give a consistent description on the measured ℓ distributions. The present work reveals that the velocity and collision partner species dependence effects as well as electronic correlations for multielectron processes should be included in an improved model. Alternatively, in future modeling to interpret high-resolution astrophysical observations the more elaborate quantum-mechanical calculations may be resorted to with confidence.

Published: December 2022

The investigation of metal-containing interstellar molecules stands as a prolific field for current astrochemical research. However, the search for many of these systems in the interstellar medium has remained inaccessible to date due to the lack of preliminary spectroscopic data. In this context, pioneering theoretical studies have inspired quantum chemists to study new appealing candidates to enable their subsequent search in space. The aim of this study is to provide high-level theoretical spectroscopic signatures of the tetratomic system [Na, N, C, O]. We have performed a thorough exploration of its potential energy surface employing different state-of-the-art quantum chemical methods and nine different species have been characterized. Moreover, we have evaluated the stability of the most stable isomers against dissociation and explored their main isomerization processes. We therefore suggest sodium isocyanate (NaNCO,1Σ) and sodium cyanate, (NaOCN, 1Σ) as the most relevant candidates for laboratory and interstellar detection. To aid in their eventual spectral search by means of rotational spectroscopy, we report a complete set of the required spectroscopic parameters including the nuclear quadrupole coupling constants, which are needed to interpret their complex hyperfine structure. NaNCO and NaOCN present exceptionally high values of the electric dipole moment (11.4 and 13.6 Debyes, respectively at the CCSD(T,rw)/aug-cc-pVTZ level), which strongly support to perform an eventual radio astronomical search. Furthermore, both isomers exhibit rather small vibrational frequencies, which indicates that these species are certainly floppy molecules.

Besides the two formerly described species, five new species are identified using a combination of morphology and molecular characters (COI, Kimura 2-parameter distances), four species from Sumatra and one from the Philippines. They are described and illustrated at the larval stage. Additionally, a complementary description of larva and adult stages of the generic type speciesB. javanicuscomb. nov.as well as the first description of the eggs are provided. Furthermore, new reports ofB. javanicuscomb. nov.andB. sabahensiscomb. nov.are indicated. The distribution ofBranchiobaetisgen. nov.includes the Indonesian Sunda Islands, Borneo, and the Philippines. A key to the larval stage of all species is provided.
Recognizing and Addressing the Needs of Sex Trafficking Victims
Authors: Camak Deborah
Published: December 2022

Sex trafficking is a global crime enslaving persons of all ages and across all borders, and providers can be challenged to locate and recognize victims. Trafficked victims present with varied and complex healthcare needs requiring unique and tailored interventions. This investigative project sought to situate the existing literature with experiences described by professionals who work with trafficking survivors. Findings from the report indicate that many survivors report seeking care and receiving treatment from nurses while trafficked yet failing to be identified by nurses or other healthcare providers as a trafficking victim. This article addresses the scope of sex trafficking, indicators used to recognize victims of sex trafficking, the critical need for nursing to be knowledgeable of sex trafficking, and concludes with a discussion of nurses’ responsibility to address victims’ diverse needs.

The summation inequality is essential in creating delay-dependent criteria for discrete-time systems with time-varying delays and developing other delay-dependent standards. This paper uses our rebuilt summation inequality to investigate the robust stability analysis issue for discrete-time neural networks that incorporate interval time-varying leakage and discrete and distributed delays. It is a novelty of this study to consider a new inequality, which makes it less conservative than the well-known Jensen inequality, and use it in the context of discrete-time delay systems. Further stability and passivity criteria are obtained in terms of linear matrix inequalities (LMIs) using the Lyapunov-Krasovskii stability theory, coefficient matrix decomposition technique, mobilization of zero equation, mixed model transformation, and reciprocally convex combination. With the assistance of the LMI Control toolbox in Matlab, numerical examples are provided to demonstrate the validity and efficiency of the theoretical findings of this research.
Asymptotic behavior of survival probability for a branching random walk with a barrier
Authors: Lv You
Published: December 2022

Consider a branching random walk with a mechanism of elimination. We assume that the underlying Galton-Watson process is supercritical, thus the branching random walk has a positive survival probability. A mechanism of elimination, which is called a barrier, is introduced to erase the particles who lie above $ ri+\varepsilon i^{\alpha} $ and all their descendants, where $ i $ presents the generation of the particles, $ \alpha > 1/3, \varepsilon\in{{\mathbb{R}}} $ and $ r $ is the asymptotic speed of the left-most position of the branching random walk. First we show that the particle system still has a positive survival probability after we introduce the barrier with $ \varepsilon > 0. $ Moreover, we show that the decay of the probability is faster than $ e^{-\beta'\varepsilon^{\beta}} $ as $ \varepsilon\downarrow 0 $, where $ \beta', \beta $ are two positive constants depending on the branching random walk and $ \alpha $. The result in the present paper extends a conclusion in Gantert et al. (2011) in some extent. Our proof also works for some time-inhomogeneous cases.

Dielectric properties of the BiFe0.5Cr0.5O3 ceramics synthesized under high pressure were investigated in a broad frequency range (20 Hz – 1 GHz) between 200 and 500 K. It was revealed that the ceramics exhibit electrical conductivity above 300 K. Below 300 K, a dielectric dispersion caused by ferroelectric domains was observed. It was found that the conductivity follows the Almond–West law, which allowed us to determine a DC contribution (σDC). From the σDC values obtained at different temperatures, the activation energy (EA = 0.302 ± 0.006 eV) was calculated using the Arrhenius law.

In this paper, we present the dielectric and piezoelectric properties of tetragonal 0.8Na0.5Bi0.5TiO3-0.2BaTiO3 modified with NaNbO3 ((1-x)[0.8Na0.5Bi0.5TiO3-0.2BaTiO3]-xNaNbO3). Our experimental study has revealed that the ferroelectric phase in these compositions is suppressed with the increase of sodium niobate concentration. A broad anomaly, resembling relaxor ferroelectrics, appears in the 325–450 K temperature interval. The investigation of the electric field dependence of polarization has indicated that the double hysteresis loop behaviour is characteristic of the modified compositions, which is associated with the 1st order phase transition under the applied electric field. The experiments below room temperature have revealed that the range of stability of the ferroelectric phase is shifted to lower temperatures upon the increase of sodium niobate concentration. The electromechanical displacement in the modified compositions shows a similar maximum displacement in the whole concentration range. The electromechanical response in 0.8Na0.5Bi0.5TiO3-0.2BaTiO3 solid solutions is due to the piezoelectric effect, while, in the mixed compositions, it is related to the jump-like change of the lattice constants in the vicinity of electric fieldinduced 1st order phase transition.
Façonner les rôles sexués et discipliner le corps féminin : les discours de distribution de prix en Guadeloupe et en Martinique, 1905-1920
Authors: Palmiste Clara
Published: December 2022

Cette étude se propose d’explorer, à partir des discours de distribution de prix, le rôle de l’école républicaine dans le façonnage des rôles sexués durant la période postérieure à la laïcisation des écoles, où la politique scolaire est intimement liée à la politique coloniale, toutes deux aspirant à éduquer et civiliser des populations jugées moralement et intellectuellement inférieures. Dans le contexte antillais, il s’agit d’en appréhender les spécificités, d’examiner les modèles masculins et féminins célébrés par l’école et le corps social, d’interroger l’imbrication de ces représentations sexuées avec d’autres représentations liées à la race et à la classe, et de voir la manière dont ils participent au maintien de l’ordre social, aux tentatives de contrôle du corps féminin (la peur de la « masculinisation » des jeunes filles) et à la poursuite d’un idéal féminin calqué sur le modèle bourgeois métropolitain.
La quête de reconnaissance dans la socialisation de garçons et d’adolescents martiniquais
Authors: Kabile Joëlle
Published: December 2022

Cet article questionne les modalités de la reconnaissance dont peuvent bénéficier les garçons et les adolescents lors de la socialisation masculine dans la société martiniquaise. Celle-ci, reposant sur des modes d’éducation souvent autoritaires, complique la valorisation et la reconnaissance mais ne l’exclut pas pour autant. L’importance du groupe des pairs comme acteur de la reconnaissance se révèle également fondamentale mais expose aussi les individus au mépris et à l’ambivalence.

RESIDÊNCIA TERAPÊUTICA: PERMANÊNCIAS E RUPTURAS NAS PRÁTICAS DE TRABALHO
Authors: Bragheto Ferreira Cintia , Da Silva Ferreira Caroline
Published: December 2022

No Brasil, o funcionamento das residências terapêuticas tende a apresentar desafios, tais como a falta de apoio social, que podem dificultar a produção do cuidado em saúde e afetar os trabalhadores do serviço. Por isso, a presente pesquisa tem como objetivo relatar a experiência de realização de oficinas com profissionais de uma residência terapêutica, além de descrever os desafios e potencialidades enfrentados pelos profissionais ao produzirem o cuidado em saúde. Para tanto, realizou-se um estudo qualitativo-descritivo, do tipo relato de experiência, embasado na abordagem metodológica do construcionismo social. Os dados foram coletados a partir de entrevistas semiestruturadas, gravadas, com cinco profissionais de uma residência terapêutica, seguidas por quatro oficinas, adaptadas a partir da Metodologia ‘Ritmos da Vida’, e diários de campo da pesquisadora. A partir dos relatos apresentados percebe-se que as participantes do estudo relataram muito mais desafios do que potencialidades para a produção do cuidado em saúde mental. Contudo, os espaços de fala e de escuta ofertados às profissionais parecem ter disponibilizado reflexões que possibilitaram a construção de sentidos positivos relacionados ao trabalho em saúde mental.

A AUTORA E OS BICHOS: A VIDA ÍNTIMA DE ULISSES
Authors: Scorsolini-Comin Fabio
Published: December 2022

O objetivo deste estudo teórico é problematizar a presença do cachorro Ulisses como alter ego de Clarice Lispector no livro infantil Quase de verdade (1978). Ulisses era também o cachorro da autora, mencionado por ela em diversas entrevistas e no livro Um sopro de vida (1999) em termos de sua humanidade, que o habilitaria a compreender Clarice de um modo particular e mais próximo, quase cúmplice. Essa humanidade se concretiza quando ele assume a narração em Quase de verdade, posicionando Clarice como sua intérprete. A relação com o bicho revela-se de modo simbiótico, recuperando tanto uma experiência mais instintiva da autora como permitindo a fruição das emoções presentes no animal, em um processo de complementaridade. Como vértices de um mesmo eu, discute-se em que medida Ulisses também funciona como um intérprete de Clarice, propondo a ela uma experiência concreta de viver que ultrapassaria a construção de uma inteligibilidade racional. A dimensão do viver, sensorial e corpóreo, desse modo, apresenta-se como superior à atividade compreensiva, aproximando Clarice do universo íntimo, básico e igualmente selvagem tão bem vivido e corporificado por Ulisses, capitaneado à posição de um alter ego puro capaz de ensiná-la a viver com a sua própria animalidade.
