The Game/Play Aspect of Mythology: Genesis, Staging and Experience
Authors:   Nikolay I. Petev Vladimir State University, Petev Nikolay I.
Published: May 2023

This paper analyses and compares two related phenomena, namely, game/play and mythology. Particular attention is given to the practical side of mythology, i.e. its implementation within the framework of rituals and other religious practices. First, the study investigates the correlation between mythology/ ritual and playing in terms of their historical transformations, in particular, in the aspect of dependence of the aforementioned religious elements on the game/play and their derivation from the game/play. Next, the author compares the following elements that correspond to the structure of the phenomenon of the game/ play and myth/cult actions: staging (illustrativeness, visualization), experience, dressing up (special role of costume and other attributes), space and time, participants (group), rules, language, and implementation channel. This paper investigates staging and experience. The purpose of the study is to identify and analyse the game/play aspects of mythology and ritual, as well as to establish their dependent or independent relation to the game/play. The main task is a comparative analysis that will determine whether the components of religious practice and playing are identical or just similar. To fulfil the purpose and the task, a number of methods are applied here: analysis and synthesis, comparative historical method, as well as religious, cultural, and psychological approaches. The generally accepted comparative religious method is not applicable in this case due to the specific nature of one of the objects under study (games), in contrast to the general comparative method. As a result of the research, the author comes to the following conclusions: 1) no phylogenetic or historical dependence of mythology and cult actions on the game/play was revealed; 2) ritual practices often resemble such a class of games as Mimicry and have tendencies similar to paidia and ludus; 3) the practical side of mythology is autonomous from the phenomenon of the game/play; 4) a special existential tension inherent in both the game/play and ritual practices was identified. However, the contents of these states are not identical, each having their own characteristics and peculiarities. The established contradictions do not imply ascent to some unity that would determine the dependence of the myth/ritual, making the latter just a derivative of playing (a form of the game/play).
Discourse as a Result of Inter-Style Interactions: A Case of Religious and Ecclesiastical Russian- and English-Language Communication
Authors:   Southern Federal University, Sukhomlinova Marina A.
Published: May 2023

Review of the monograph: Nikolaev S.G., Karagodskaya Yu.S. Interaction of the Religious and Ecclesiastical Style with Related Spheres: Ontology and Expressology. Rostov-on-Don, 2022. 152 p. (in Russ.) The reviewed monograph studies the space of discourses reflecting the interaction of the religious and ecclesiastical style with other communicative spheres: official, scientific, literary, journalistic, and advertising. The self-sufficiency of the religious and ecclesiastical style and its isolation are deeply connected with its interaction with related communicative spheres; this interaction is realized in the style’s essence and expression. In the book, the ontological and expressological aspects of this interaction are described, its linguistic prerequisites are identified, its conditions are systematized, and the systemic significance of the correlation between various discourses is determined. Moreover, the interrelation between ontology and expression in the selected material is established and the vectors of integration of expressive resources in terms of their interaction are characterized, taking into account mutual attraction and repulsion.
Public Opinion and Public Space: The Semantic Relationship Within the Systems-Communicative Approach
Authors:   Lomonosov Moscow State University, Sapan Il’ya E.
Published: May 2023

In this article, the author investigates two social phenomena, namely, public opinion and public space, within the framework of the systems-communicative approach. The study is relevant due to the fact that today, both in Russia and beyond, the topic of public opinion, publicity and mass beliefs has received great attention from various spheres of public life, in particular, the political sphere, which can automatically generate research interest within the academic environment. The theoretical basis for this paper is Niklas Luhmann’s general social theory. The purpose of the study is to explicate the special characteristics of public opinion as a truly unique communication space necessary for the political system to reproduce itself. The author considers the problem of the interpretation of public opinion and its characteristics as a communicative phenomenon and consistently outlines the construct of Luhmann’s theoretical positions. Recognizing the special role of the media as an actor that gives a distinct shape to public opinion, the author demonstrates that the popular view of mass media as a manipulator of mass beliefs is often exaggerated and even prescribed: being guided by the desire to create a sensation, mass media can offer or even impose an agenda, but cannot force its full acceptance. It is postulated here that not only does the news seek its reader, but the reader seeks his/her news. Based on these positions, the author concludes that, within the framework of the political system, public opinion is a communicative tool for making universally binding decisions, rather than a sum of individual views, thus demonstrating the mythological content of the concepts of democracy, elections, and popular will.
Socio-Philosophical Interpretation of Sociality as a Universal Category
Authors:   Omsk State Pedagogical University, Aksyutina Zulfia A.
Published: May 2023

The issue of addressing the phenomenon of sociality and its research are designed to help identify the characteristics of its typological, dynamic, structural and functional properties. The problems of sociality are most acutely actualized during crises, becoming the basis for studying society. The purpose of this article was to identify and describe the categorical series of sociality based on the generalization of its characteristics. In the course of the research, the author applied the categorical systems methodology. The theoretical analysis revealed no unified interpretation of the category of sociality. Sociality is often considered to be a result of social reality, a human trait, although there are attempts to consider sociality as a general category in relation to a specific category, namely, social reality. Sociality reflects a person’s ability to exist in society, to be its full member. Using the results of the theoretical analysis, generalizations and conclusions on understanding the category of sociality, the author developed a model of the structure and elements of the categorical series of sociality based on the categorical pendulum method. This model includes the following categories: society, social life, social reality, culture, historical development, politics, citizenship, sociability, exchange, connections, dependence and interdependence. The paper revealed sociality trends in the pessimal scenario of its development. Asociality, prosociality and antisociality, in contrast to sociality, manifest themselves to varying degrees. At the same time, the information society contributes to the formation of asociality, while prosociality is a consequence of the sociocultural penetration of alien values, and antisociality is seen as a consequence of alienation, including in upbringing. Further study into the pessimal tendencies of sociality will contribute to new scientific research aimed to fulfil preventive practice-oriented tasks of counteracting the indicated antagonistic types of sociality.

The analysis of randomized response “ever” and “last year” questions: A non-saturated Multinomial model
Authors: Sayed Khadiga H. A. , Cruyff Maarten J. L. F. , van der Heijden Peter G. M.
Published: May 2023

Randomized response (RR) is a well-known interview technique designed to eliminate evasive response bias that arises from asking sensitive questions. The most frequently asked questions in RR are either whether respondents were “ever” carriers of the sensitive characteristic, or whether they were carriers in a recent period, for instance, “last year”. The present paper proposes a design in which both questions are asked, and derives a multinomial model for the joint analysis of these two questions. Compared to the separate analyses with the binomial model, the model makes a useful distinction between last year and former carriers of the sensitive characteristic, it is more efficient in estimating the prevalence of last year carriers, and it has a degree of freedom that allows for a goodness-of-fit test. Furthermore, it is easily extended to a multinomial logistic regression model to investigate the effects of covariates on the prevalence estimates. These benefits are illustrated in two studies on the use of anabolic androgenic steroids in the Netherlands, one using Kuk and one using both the Kuk and forced response. A salient result of our analyses is that the multinomial model provided ample evidence of response biases in the forced response condition.

Cement is one of the binders which is commonly used as a concrete-forming material. Currently, there is a lot of coffee husk waste in Takengon, Central Aceh Regency, which contains silica. The basis of using coffee husk ash and OPC cement as an adhesive on the normal compressive strength of concrete. This study aims to determine the influence of using coffee husk ash and OPC cement as an adhesive on the compressive strength of normal concrete at a percentage of 5%, 10% and 15%. The research specimen is cylindrical shape with 15 cm diameter and 30 cm height. The test was carried out at the age of 7 and 28 days by using a compressive strength testing machine. The method of making the specimen is in accordance with the SNI 7656-2012 standard. It is found from the results in the laboratory, coffee husk ash obtains silicate compounds (SiO2) 29.11%, magnesium oxide (MgO) 4.92%, calcium oxide (Cao) 5.33%, ferrioxide (Fe2O3) 4.25% and aluminum oxide (Al2O3). The average compressive strength test results of 7-day old concrete at the percentage of 5% coffee husk ash mixture was 20.21 MPa, at 10% was 20.03 MPa and at 15% was 17,25 MPa. The average compressive strength of concrete at 28 days of age with 5% coffee husk ash mixture is 20.27 MPa at 10% coffee husk ash mixture percentage 19.70 MPa and 15% coffee husk ash mixture 15.46 MPa. Comparison of the results of the compressive strength test for concrete at 7 and 28 days was higher for concrete at 7 days. The results of the different compressive strength tests between the ages of the concrete are caused by the high percentage of coffee husk ash mixture where the higher the coffee husk ash percentage, the weaker the adhesion to the concrete. The percentages of coffee husk ash and OPC cement that meet the design compressive strength of 20 MPa are at 5% and 10% respectively.

Objectives. The objective of the study was to investigate the clinical performance of two different resin-based materials 6 months after their placement in dental non-carious cervical lesions (NCCL). This study also aimed to evaluate the effects of the materials on periodontal tissues in terms of clinical changes of several periodontal parameters. Material and methods. NCCLs characteristics (localization, morphology, dimensions) were preoperatively recorded. The clinical behavior of the restorations based on the modified United States Public Health Service (USPHS) criteria and periodontal parameters (plaque index, bleeding index, probing depth, and attachment loss) were assessed at baseline and after 1, 3 and 6 months. Results. No significant modifications were recorded for the modified USPHS criteria 6 months after the placement of NCCL restorations excepting postoperative hypersensitivity which was associated with 4 restorations after 6 months. Significant improvements of plaque and bleeding indices were recorded, while no significant modifications were noted for the other periodontal parameters. Conclusions. Considering the clinical success related to the good clinical behavior and the positive effect of the restorations on the periodontal status, the experimental conventional composites and giomers could be considered as a good therapeutic option for the restoration of NCCLs.

Dental-maxillary anomalies are accompanied by changes in the interbasal maxillary ratio in all reference planes, with influences on the functionality of articular structures. These joint changes not detected in time and not included in the treatment plan may worsen while wearing fixed appliances, as orthodontic treatment changes the cranio-mandibular position and causes cranio-mandibular reshaping. The articulator is an instrument that reproduces more or less all mandible movements. TMJ characteristics of skeletal dento-maxillary anomalies, especially class II sagittal pattern mainly reflected in condylar position rather than morphology. TMJ of different vertical patterns differed more in joint spaces, position of condyle and glenoid fossa than in morphologic measurements. Vertical position of glenoid fossa and proportion of posterior condyle increased gradually from hypodivergent to hyperdivergent. Highest glenoid fossa position, maximum ratio of posterior positioned condyle, smallest joint spaces, shallowest glenoid fossa depth, and narrowest condylar long axis diameter were found in skeletal class. The patients with high angle have considerable joint instable factors, and we should especially pay attention when orthodontic treatment is carried out on them. The condyle-fossa position and morphology differ with various vertical facial patterns in individuals with skeletal Class II mandibular retrognathism. These differences could be considered during temporo-mandibular diagnosis and orthodontic treatment
The Infrared Colors of 51 Eridani b: Micrometeoroid Dust or Chemical Disequilibrium?

Published: May 2023

We reanalyze the near-infrared spectra of the young extrasolar giant planet 51 Eridani b, which was originally presented in Macintosh et al. and Rajan et al. using modern atmospheric models, including a self-consistent treatment of disequilibrium chemistry due to turbulent vertical mixing. In addition, we investigate the possibility that significant opacity from micrometeors or other impactors in the planet’s atmosphere may be responsible for shaping the observed spectral energy distribution (SED). We find that disequilibrium chemistry is useful for describing the mid-infrared colors of the planet’s spectra, especially in regard to photometric data at the M band around 4.5 μm, which is the result of superequilibrium abundances of carbon monoxide, while the micrometeors are unlikely to play a pivotal role in shaping the SED. The best-fitting, micrometeoroid dust–free, disequilibrium chemistry, patchy cloud model has the following parameters: effective temperature T
eff = 681 K with clouds (or without clouds, i.e., the grid temperature T
grid = 900 K), surface gravity g = 1000 m s−2, sedimentation efficiency f

In late 2014, four images of supernova (SN) “Refsdal,” the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images’ discovery, the SN was predicted to reappear within hundreds of days at a new position ∼8″ away in the field. The observed reappearance in late 2015 makes it possible to carry out Refsdal’s original proposal to use a multiply imaged SN to measure the Hubble constant H
0, since the time delay between appearances should vary inversely with H
0. Moreover, the position, brightness, and timing of the reappearance enable a novel test of the blind predictions of galaxy-cluster models, which are typically constrained only by the positions of multiply imaged galaxies. We have developed a new photometry pipeline that uses DOLPHOT to measure the fluxes of the five images of SN Refsdal from difference images. We apply four separate techniques to perform a blind measurement of the relative time delays and magnification ratios between the last image SX and the earlier images S1–S4. We measure the relative time delay of SX–S1 to be

The driving of turbulence in galaxies is deeply connected with the physics of feedback, star formation, outflows, accretion, and radial transport in disks. The velocity dispersion of gas in galaxies therefore offers a promising observational window into these processes. However, the relative importance of each of these mechanisms remains controversial. In this work we revisit the possibility that turbulence on galactic scales is driven by the direct impact of accreting gaseous material on the disk. We measure this effect in a disk-like star-forming galaxy in IllustrisTNG, using the high-resolution cosmological magnetohydrodynamical simulation TNG50. We employ Lagrangian tracer particles with a high time cadence of only a few million years to identify accretion and other events. The energies of particles are measured by stacking the events in bins of time around the event. The average effect of each event is measured by fitting explicit models for the kinetic and turbulent energies as a function of time. These measurements are corroborated by cross-correlating the turbulent energy with other time series and searching for signals of causality, i.e., asymmetries across zero time lag. We find that accretion contributes to the large-scale turbulent kinetic energy even if it does not dominate in this ∼5 × 109
M
⊙ stellar mass galaxy. Extrapolating this finding to a range of galaxy masses, we find that there are regimes where energy from direct accretion may dominate the turbulent energy budget, particularly in disk outskirts, galaxies less massive than the Milky Way, and at redshift ∼2.

The precision of our new M31 mass estimates (23%–50%) improves by a factor of two compared to previous mass estimates using a similar methodology with just one satellite galaxy, and places our results among the highest-precision M31 estimates in recent literature. Furthermore, our results are consistent with recently revised estimates for the total mass of the Local Group (LG), with the stellar mass–halo mass relation, and with observed kinematic data for both M31 and its entire population of satellites.

Toward Accurate Modeling of Galaxy Clustering on Small Scales: Halo Model Extensions and Lingering Tension
Authors: Beltz-Mohrmann Gillian D. , Szewciw Adam O. , Berlind Andreas A. , Sinha Manodeep
Published: May 2023

This paper represents an effort to provide robust constraints on the galaxy–halo connection and simultaneously test the Planck ΛCDM cosmology using a fully numerical model of small-scale galaxy clustering. We explore two extensions to the standard Halo Occupation Distribution model: assembly bias, whereby halo occupation depends on both halo mass and the larger environment, and velocity bias, whereby galaxy velocities do not perfectly trace the velocity of the dark matter within the halo. Moreover, we incorporate halo mass corrections to account for the impact of baryonic physics on the halo population. We identify an optimal set of clustering measurements to constrain this “decorated” HOD model for both low- and high-luminosity galaxies in SDSS DR7. We find that, for low-luminosity galaxies, a model with both assembly bias and velocity bias provides the best fit to the clustering measurements, with no tension remaining in the fit. In this model, we find evidence for both central and satellite galaxy assembly bias at the 99% and 95% confidence levels, respectively. In addition, we find evidence for satellite galaxy velocity bias at the 99.9% confidence level. For high-luminosity galaxies, we find no evidence for either assembly bias or velocity bias, but our model exhibits significant tension with SDSS measurements. We find that all of these conclusions still stand when we include the effects of baryonic physics on the halo mass function, suggesting that the tension we find for high-luminosity galaxies may be due to a problem with our assumed cosmological model.
Third Epoch HST Imaging of a Nonradiative Shock in the Cygnus Loop Supernova Remnant
Authors: Sankrit Ravi , Blair William P. , Raymond John C.
Published: May 2023

We present new HST/WFC3 optical images of a region in the northeastern part of the Cygnus Loop supernova remnant, which includes a well-studied Balmer-line filament. These data represent the third epoch of HST Hα imaging and a second epoch of [O iii] λ5007 imaging of that particular filament. The Hα images were used to measure the proper motions at various locations along the shock front, and the values ranged from 55 to 85 mas yr−1 with a median value of 70 mas yr−1, which corresponds to a shock velocity of 240 km s−1. The proper motions between epochs 1 and 2 were the same as between epochs 2 and 3, implying that there has been no measurable deceleration of the shock in the 22 yr period between the first and third epochs. The range of proper motions (and therefore shock velocities) along the filament indicate variations of over a factor of two in the preshock density. The [O iii] emission is prominent toward one end of the filament where the shock has transitioned from nonradiative to radiative. The proper motion is smaller than for the Hα filaments, and it corresponds to a shock velocity of about 155 km s−1. The images obtained about 18 yr apart show that the [O iii] morphology has not changed, which places limits on any short-timescale variations due to catastrophic cooling or thermal instabilities. We find that the effective shock age is less than the eddy turnover timescale, which implies that turbulence has not yet influenced the dynamics of the shock.
Understanding the Chemical Evolution of Blue Edge-on Low Surface Brightness Galaxies

Published: May 2023

We present a sample of 330 blue edge-on low surface brightness galaxies (ELSBGs). To understand the chemical evolution of ELSBGs, we derived the gas-phase abundance and the [α/Fe] ratio. Compared with star-forming galaxies, ELSBGs show a flatter trend in the mass–metallicity (M
*–Z) relation, which suggests that the oxygen abundance enhancement is inefficient. We focused on 77 ELSBGs with H i data and found that the closed-box model cannot explain their gas fraction and metallicity relation, which implies that infall and/or outflow is needed. We derived the [α/Fe] ratio of normal ELSBG (<109.5
M
⊙) and massive ELSBG (> = 109.5
M
⊙) using single stellar population grids from the MILES stellar library. The mean [α/Fe] ratios are 0.18 and 0.4 for normal ELSBG and massive ELSBG, respectively. We suggest that the long timescales of star formation and/or metal-rich gas outflow events caused by SNe Ia winds are likely to be responsible for the α-enhancement of massive ELSBGs.

Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted that different scales of flares share the same physical process. Here we present the newly developed semiautomated jet identification algorithm and its application for detecting more than 1200 off-limb solar jets during Solar Cycle 24. Power-law distributions have been revealed between the intensity/energy and frequency of these events, with indices found to be analogous to those for flares and coronal mass ejections (CMEs). These jets are also found to be spatially and temporally modulated by the solar cycle, forming a butterfly diagram in their latitudinal-temporal evolution, experiencing quasi-annual oscillations in their analyzed properties, and very likely gathering in certain active longitudinal belts. Our results show that coronal jets display the same nonlinear behavior as that observed in flares and CMEs, in solar and stellar atmospheres, strongly suggesting that they result from the same nonlinear statistics of scale-free processes as their counterparts in different scales of eruptive events. Although these jets, like flares and other large-scale dynamic phenomena, are found to be significantly modulated by the solar cycle, their corresponding power-law indices still remain similar.
Case A or Case B? The Effective Recombination Coefficient in Gas Clouds of Arbitrary Optical Thickness
Authors: Nebrin Olof
Published: May 2023

In calculations of the ionization state, one is often forced to choose between the Case A recombination coefficient α
A (sum over recombinations to all hydrogen states) or the Case B recombination coefficient α
B (sum over all hydrogen states except the ground state). If the cloud is optically thick to ionizing photons, α
B is usually adopted on the basis of the “on-the-spot” approximation, wherein recombinations to the ground state are ignored because they produce ionizing photons absorbed nearby. In the opposite case of an optically thin cloud, one would expect the Case A recombination coefficient to better describe the effective recombination rate in the cloud. In this paper, I derive an analytical expression for the effective recombination coefficient in a gas cloud of arbitrary optical thickness which transitions from α
A to α
B as the optical thickness increases. The results can be readily implemented in numerical simulations and semi-analytical calculations.

The existence of Himalayan long-eared bats, Plecotus homochrous (Chiroptera, Vespertilionidae), in China has not been previously confirmed. In this study, four bats captured with harp traps from two sites in the Maoershan National Nature Reserve in Guangxi, China were investigated. These bats have long, wide auricles, each with a prominent tragus. The length of each auricle is about the same as that of a forearm. Hairs on the ventral fur have a dark base with mixed grey and yellowish tips; those on the dorsal fur also have a dark base and are bicolored with brown tips. The thumbs are very short. A concavity is present in the front of the dorsal side of the cranium. Based on morphological characteristics and phylogeny using Cyt b gene sequences, these bats were identified as P. homochrous, thus confirming the existence of Himalayan long-eared bats in China.

Par de nouvelles mesures, nous testons et quantifions l’importance relative de ces deux pratiques dans le monde. Codes JEL : J13, J16, O10.
Finance digitale en République démocratique du Congo : quelles leçons retenir pour les exclus du système financier de la province du Haut-Katanga ?
Authors: Kamenga Mapurita Christian , Mayoukou Célestin
Published: May 2023

Si la finance digitale est reconnue comme un outil qui facilite le développement financier, il devient alors impératif de discuter de son apport dans la lutte contre l’exclusion financière. En effet, il existe un manque de consensus autour de la relation entre le développement financier et l’exclusion financière. Codes JEL: G23, O35.

Pauvreté, santé. Le subjectif comme révélateur de la dureté des rapports sociaux
Authors: Duvoux Nicolas
Published: May 2023

Cet article montre que la mesure des inégalités en santé et dans le domaine de la pauvreté fait, conjointement, apparaître l’intérêt et l’importance des variables subjectives. Celles-ci sont parfois considérées comme étant à l’opposé d’analyses donnant la première place aux conditions matérielles d’existence et aux intérêts de classe. Nous montrerons que ces variables permettent de saisir les inégalités de classe d’abord à partir des inégalités de santé, ensuite des mesures subjectives de la pauvreté.
L’impact de la pauvreté sur le développement et la santé des jeunes enfants
Authors: Gorza Maud , Cardoso Thierry
Published: May 2023

La grossesse et la petite enfance sont des moments-clés pour le développement des enfants, leur santé et leur bien-être tout au long de la vie. Naître et grandir dans une famille vivant dans la pauvreté est reconnu comme un facteur d’adversité important dont l’impact marque les indicateurs de santé périnatale et développementale. Cet article explore l’altération des systèmes de réponses au stress qui en découle et les conséquences sur la qualité des interactions parent-enfant. Il met en évidence des leviers d’action pour influencer favorablement le développement des enfants.

Paternité et parentalité dans des contextes de violences conjugales : quand des hommes s’expliquent
Authors: Ranchin Bruno
Published: May 2023

À partir d’une longue expérience de coanimation de groupes de parole dans l’association avac en tant que thérapeute auprès d’hommes auteurs de violences conjugales, l’auteur explore les notions de paternité et de parentalité dans un contexte de violences conjugales. Des paroles des hommes recueillies dans les séances, il met en lien les réalités de l’exercice de la parentalité et tente d’approfondir ce que peuvent apporter (ou pas) des interventions sur l’engagement paternel.
Le statut juridique des aidantes et des aidants. La situation française au regard du droit européen
Authors: Martin Philippe
Published: May 2023

Le rôle assumé par les aidantes et aidants auprès des personnes handicapées ou des personnes âgées fait l’objet de l’attention du législateur, tant au plan national qu’européen. Un statut des aidants se cherche, autour de plusieurs questions : reconnaissance du travail de l’aidant et ouverture de droits sociaux ; conciliation de l’aide avec une activité professionnelle salariée ; santé de l’aidant. Le droit européen appréhende cette problématique selon un prisme particulier, qui tient au fait que l’Union européenne n’est pas juridiquement outillée pour imposer un cadre commun aux politiques sociales nationales. Le droit français s’est dès lors construit de manière relativement autonome par rapport au droit européen. Pour l’heure, le « statut » des aidants demeure fragmenté et peu lisible en France, en raison essentiellement de la prégnance d’une logique sectorielle qui distingue handicap et dépendance et cloisonne les catégories juridiques.
La formation des aidantes et des aidants : au-delà de la concurrence des savoirs, une diversité des besoins et des pratiques
Authors: Giraud Olivier
Published: May 2023

Depuis la fin des années 2000, les formations destinées aux aidantes et aidants de personnes âgées ou en situation de handicap se sont répandues. Censées améliorer la qualité du soin prodigué, protéger la santé des personnes aidantes, mais aussi renforcer le lien entre aidant et aidé, ces formations font parfois l’objet de critiques. Engageant les personnes aidantes dans une certaine technicité ou professionnalité, ces mesures les éloigneraient de leur rôle affectif primordial. Aujourd’hui encore, un petit nombre d’entre elles font un recours concret aux mesures de formation. Une analyse d’entretiens approfondis auprès des personnes aidantes a montré que les relations qu’elles entretiennent aux savoirs formels dépendent non seulement de leur volonté et capacité d’autonomie dans la conduite des soins, mais aussi du niveau de conflictualité entretenu avec les aidantes et aidants professionnels. Ces deux dimensions permettent de dégager quatre rapports types aux savoirs formels entretenus par les personnes aidantes.
Comprendre les besoins des proches aidants pour mieux agir : une problématisation au prisme du non-recours
Authors: Revil Hélèna , Gand Sébastien
Published: May 2023

À présent reconnus politiquement et médiatiquement, beaucoup de proches aidants de personnes en perte d’autonomie n’ont pas recours aux droits, services, aides et/ou prestations auxquels ils pourraient prétendre. Cet article propose de s’interroger sur l’effectivité de l’offre destinée aux proches aidants et sur les formes que prend ce non-recours. La difficulté à appréhender les besoins propres des proches aidants ainsi que le caractère hétérogène de l’offre qui leur est destinée au niveau des territoires contribuent à expliquer la rencontre en partie manquée entre l’offre et la demande. Il est également utile de s’intéresser aux logiques de recours différenciées des proches aidants ainsi qu’aux représentations qu’ont les professionnels du social et de la santé des offres et de ce que peut être leur propre rôle vis-à-vis des proches aidants.
« Avoir le choix » : un enjeu de l’éducation contemporaine qui n’est pas sans conséquence psychopathologique…
Authors: Marcelli Daniel
Published: May 2023

Qu’est-ce que choisir ? Classiquement, un compromis entre le désir inconscient et la rationalité psychique. Chez l’adolescent d’aujourd’hui, le plan narcissique l’emporte sur l’objectal, ce qui implique que la transmission évolue dans son mode opératoire. Parentale, familiale, culturelle, religieuse, sociale, celle-ci construit l’adolescent. La clinique nous montre une évolution des modes de construction de ce dernier. Un détour par Aristophane permet d’analyser le refus de choisir son sexe chez les jeunes « a-genre », « neutre » ou « bi genre », en évitant l’amalgame avec les « transgenres ». Ainsi, il n’y a pas de médicament pour traiter le « refus de choix ». Un accompagnement psychothérapeutique permet à l’adolescent actuel de contourner la « fatigue de soi » et le refuge dans la passivité.
Trajectoires
Authors: Cerutti Gaëlle
Published: May 2023

Cet article propose de réfléchir à la situation de deux jeunes enfants, Tiago et Timéo, alors placés par ordonnance judiciaire dans une Maison d’enfants à caractère sociale. L’hypothèse principale à notre réflexion sera de soutenir que le maintien des droits de visite libres au domicile des parents dans le cadre du placement est le résultat d’une approche et d’un état d’esprit seulement objectivant posé sur la situation de cette famille. En filigrane, nous proposons de penser que le pli de la pédopsychiatrie donné aux origines de cette situation a contaminé celui de la protection de l’enfance et avec lui, le monde de la justice et des services sociaux, « tournés en rond » et tous ensemble vers la rééducation de ces enfants et l’aide apportée aux parents. Nos hypothèses de pensée nous conduiront à l’abord des notions et idées suivantes : le mimétisme des dispositifs sociaux — La bascule vers l’ouverture au contact d’une altérité compréhensive — L’émergence de la subjectivité écrasée — Le contact séparant.
Study of nonlinear generalized Fisher equation under fractional fuzzy concept
Authors: Usman Muhammad , Khan Hidayat Ullah , Khan Zareen A , Alrabaiah Hussam
Published: May 2023

Fractional calculus can provide an accurate model of many dynamical systems, which leads to a set of partial differential equations (PDE). Fisher's equation is one of these PDEs. This article focuses on a new method that is used for the analytical solution of Fuzzy nonlinear time fractional generalized Fisher's equation (FNLTFGFE) with a source term. While the uncertainty is considered in the initial condition, the proposed technique supports the process of the solution commencing from the parametric form (double parametric form) of a fuzzy number. Next, a joint mechanism of natural transform (NT) coupled with Adomian decomposition method (ADM) is utilized, and the nonlinear term is calculated through ADM. The obtained solution of the unknown function is written in infinite series form. It has been observed that the solution obtained is rapid and accurate. The result proved that this method is more efficient and less time-consuming in comparison with all other methods. Three examples are presented to show the efficiency of the proposed techniques. The result shows that uncertainty plays an important role in analytical sense. i.e., as the uncertainty decreases, the solution approaches a classical solution. Hence, this method makes a very useful contribution towards the solution of the fuzzy nonlinear time fractional generalized Fisher's equation. Moreover, the matlab (2015) software has been used to draw the graphs.
