The characteristics of the ice cover in the northern part of the Caspian Sea are simulated using the CICE model. The general structure of the model and the experience of its operational application in leading forecast centers are described. Calculations of the ice cover characteristics in the northern Caspian Sea for four winter seasons (October–March) in 2005–2009 are performed. The values of ice concentration and ice thickness are calculated. The comparison of the calculation results with observational data showed that the model satisfactorily reproduces the processes of ice build-up and melting. Keywords: Caspian Sea, ice cover, CICE model, ice concentration and ice thickness
The Most Vulnerable and High-Risk Groups Sensitive to Impacts of Climate Change in Arusha Region, Tanzania
Authors: Joseph Laurent
Published: April 2022

The study investigated the groups that are more vulnerable and at high risk of climate change impact among the population of the Arusha Region, where four districts out of these seven districts were purposively picked, namely Longido, Arumeru, Arusha Urban, and Karatu districts. A cross-sectional research design was adopted in this study. The systematic random sampling method was used to obtain a sample size. The sample size was 300 respondents. To explore the most vulnerable and high risked groups to impacts of climate change among the population in Arusha region, eight socioeconomic variables such as age, sex, physical ability, topographical location, house status, degree of urbanization, income status, and occupational status were investigated. The findings indicate that children and older adults aged 65> years and above, women, disabled, people in lowlands, rural dwellers, crop cultivator, temporary houses, and lower-income earners are the most vulnerable and high risked groups to impacts of climate change. The chi-square test result of association indicates that there is a statistically significant relationship between (gender, age, physical ability of the population, topographical location, occupational type of the population, degree of urbanization, and type of residential houses of the population) and climate change impacts. However, the chi-square test result of association indicates no statistically significant relationship between the level of income and the effects of climate change. The study concludes that some groups in the population are more vulnerable and high risk to climate change than others because of their location, age, health, income, occupation, and how they go about their day-to-day lives. The study recommends that the government organs critically offer assistance to the mentioned groups by formulating a friendly framework for adaptability and mitigation of climate change impacts.

Authors: Ngige Lucy W. , Ndayala Phoebe D.
Published: April 2022

The purpose of the study was to determine whether socio-demographic characteristics of People Living with HIV and AIDS (PLWHA) predicted self-disclosure of HIV seropositivity status in Kenya. A survey was conducted among a random sample of 232 respondents in Nairobi County. Data was gathered through interviews and focus group discussions. The findings indicated that 28.0% of the respondents were male and 72.0% were female. The respondents were aware of their HIV seropositive status for at least one year prior to the study. About half of the respondents (50.9%) had disclosed their HIV seropositive status, while 49.1% had not disclosed. The binary logistic regression established that the socio-demographic predictors of HIV seropositive status disclosure were educational attainment (AOR =1.266; p = 0.001), regular employment status (AOR = 1.691; p = 0.001) perceptions of financial security (AOR = 2.440; p = 0.020) and knowledge of management of HIV (AOR = 3.505; p = 0.001). However, respondents’ sex (p = 0.162), age (p = 0.921) and marital status p = 0.621) were not statistically significant predictors of HIV seropositivity disclosure to sexual partners. This implies that public health programmes should focus on educational interventions, financial security, and training on the management protocols for People Living with HIV and AIDS in order to promote HIV seropositivity status disclosure to sexual partners.
i*-Based Goal-Oriented Modeling and Requirements Specification of an Urban Railway Interlocking System
Authors: Kadakolmath Lokanna , D R Umesh
Published: April 2022

Urban railway interlocking system is a safety-critical system, for which interlocking rules are well-defined by international standards to assure safe operations. However, it is very difficult to extract all of the safety requirements in the requirements engineering stage itself and construct a goal model as well. One approach to fulfill this goal is to extract safety requirements from regulations and analyze them at the early stage of the model. Improper specifications regarding the environs of an interlocking system are realized to be accountable for any faults in requirements specifications. Furthermore, nonfunctional requirements are kept aside from requirements specifications. To make an interlocking system operate in an ultra-dependable range we need to address variability issues, so in this paper, we used i*-based goal-oriented requirements language called TGRL to address variability issues as well as blend early and late requirements. The developed model can also be visualized and analyzed using jUCMNav. Finally, the safety requirements to be verified are specified with Formal Tropos, a formal specification language for the i* model.

Published: April 2022

This work emphasizes on automatic brain tumor segmentation from three dimensional magnetic resonance imaging (3D-MRI) scan images. We have used fully convolutional neural networks (FCNN) for extracting whole tumor. The proposed architecture is based on V-Net architecture. We have developed a new activation function for training the network. ReLU is used and in experiment 2, proposed activation function is used. We have conducted two experiments for brain tumor segmentation by varying the activation functions. In experiment 1, we have also used dice loss as loss function. The proposed method is trained and tested using BraTs 2021 training dataset which contains 2000 volumes of 3D-MRI scans. The proposed method’s performance is closer to the manually segmented images by experienced neurologists available with BraTs 2021 datasets. We have obtained a mean dice score of whole tumor as 99% while using proposed activation function which is higher when compared to the existing methods. We conclude that our novel activation function proposed activation function produced enhanced accuracy and dice score when compared with ReLU activation function.
Nemzeti nagylét, nagy temető és – Batsányi
Authors: Debreczeni Attila
Published: April 2022

The narrative based on the images of „national grandeur” and „the great graveyard”, recurring in the writings of Batsányi and his contemporaries, is an imperative of inner unity in the face of „dissension,” a notion that used to stand for faction. Also, it is inseparable from memory becoming self-reflective. The concept of „dissension” can be actually dated back a long time ago; for example Mohács was considered a result of „dissension” within this tradition, even though the word itself mainly meant religious division at that time. However, in the public sphere evolving at around the end of the 18th century, these interpretations do not seem to be detectable anymore, at least there are no marked lines of continuity between publicity and the above mentioned interpretations. On the contrary, the elements of this narrative are not yet even solidified, and coexist with various other narratives. Furthermore, the ideologem based on the notion of dissension is in constant change, and thus calls attention to the potential of this historical moment for creating new cultural meanings. On the one hand, the turn of the 1780s and 1790s as an obscure period lead to the birth of this ideologem, while memory and the remembering subject came into the forefront on the other. As a result, the ideologem being formed was able to appear as a tangible cultural construction. This is how the national narrative we know as a timeless and ageless entity today emerged – also as a lieu de mémoire.
Tengerek, szigetek, mítosz
Authors: Pataki Elvira
Published: April 2022

The aim of the article is to give a panoramic view about the reception of ancient culture in contemporary Hungarian children’s literature. Because of the almost total disappearance of Latin and Greek instruction from secondary school education, the only way to present Antiquity to this generation is through literature, which carries genuine aesthetic and ethic messages. This analysis focuses on short stories and novels written in the last decade for children aged 8-12, highly influenced by the international trends of films and computer games which adapt Greek mythology for a popular entertaining narration (see the detective stories of F. Lenk or the action thriller series Percy Jackson by R. Riordan). The works analysed (Ida and the Golden Fleece by K. Baráth, Csoda and Kósza by Z. Czigány, the Siren-episode of J. Berg’s Rumini, Diabaz the Thunderbolt-throwing by E. Szakács, The Garden of Malena by K. R. Molnár), on the contrary, offer the up-to-date versions of Greek myths retold in a poetic or humorous register. Making the children acquinted by the most important elements of greco-roman culture, by the transmission of the humaniora, they help as well to create a humanistic attitude.

Published: April 2022

Organizing reliable and affordable energy supply for consumers in the Arctic area is an important and difficult task. An effective solution of this task requires taking into account many factors. This paper analyzes how various factors are taken into account in the state programs of the Arctic regions of the Rus-sian Federation, aimed at regional energy development. Natural resource, economic, social, technological, environmental, legal factors of energy supply are considered. The study is conducted on the example of four subjects of the Russian Federation, fully assigned to the Arctic zone (Murmansk Oblast, Nenets Autonomous Okrug, Yamalo-Nenets Autonomous Okrug, Chukotka Autonomous Okrug). The main research method is content analysis of the relevant information sources. The role of regional government programs in regulation of regional energy development is specified. A review of the main state programs of the considered Arctic subjects of the Russian Federation is carried out. It was revealed that the tasks of energy supply development are unevenly distributed in the state programs of the constituent entities of the Federation, and program measures are differently detailed. The content of the analyzed state programs is compared with the factors of energy supply. It is shown that regional government programs are primarily compared with economic factors. As instruments of regional policy, the state programs of the regions act as legal factors. Factors of other groups are taken into account in state programs to a lesser extent.

Published: April 2022

The article deals with the key aspects of the formation of the integrated socio-economic development of the Arctic zone of the Russian Federation (AZRF). The main purpose of the study is to create a conceptual model for balanced socio-economic development. The article uses such methods as comparison, analysis, deduction and induction. The importance of the development of these territories for the sustainable development of the country is shown. The main regulatory documents defining the development of this region are highlighted. Threats to the security of the Arctic zone of the Russian Federation are identified. The relations of other countries to the Arctic are considered. The importance of bringing the standard of living in the Arctic region closer to the average in Russia and the importance of this direction of action to reduce the negative demographic trend are outlined. Besides, the need to study the development of the Arctic region of the Russian Federation is determined not by statistical methods, but by new research methods. The importance of creating a megaproject for the development of the Arctic zone of the Russian Federation with specific measurable goals is highlighted. Such risks of this region are described as: population decline, in particular, the decline of the able-bodied population (including highly qualified personnel), the critical state of housing and communal services, the high cost of living and use of resources, the threat to environmental safety, weak diversification of production, long distances from industrial centers. Economic, social and environmental factors affecting the dynamics of the integrated socio-economic development of the Arctic region of the Russian Federation are considered. A conceptual model of balanced socio-economic development of the region was developed on the basis of a set of factors. The conceptual model of integrated development of the Arctic regions of the Russian Federation is a complex of various factors. This model can become a basis for the preparation of strategic planning documents in the regions of the Arctic zone of the Russian Federation and it is possible to compare and compare the development of the regions using this model.

Published: April 2022

The relevance of this study is due to the need to develop a fairly understandable and in some sense universal tool for assessing the socio-economic situation in municipalities (districts and settlements) with pronounced territorial specifics, with clearly insufficient statistical and information support. The authors, with references to the results of their own research and to the work of their colleagues, present a detailed analysis of the key problems characteristic of the territories of the Russian Arctic, compare them with a set of main external factors of influence in relation to municipalities. Using the SEER expert proce-dure scheme and the hierarchy analysis method, according to the two-level model proposed by the au-thors, complex point estimates of the socio-economic situation in the Arctic settlements and municipal districts of the Arkhangelsk Oblast are calculated. The paper notes that the factors that are directly related to transport accessibility have the greatest impact on the development targets of Arctic municipalities. Therefore, the transport and logistics component should be fundamental in all strategic, program and planning documents aimed at achieving the goals of socio-economic development of the Arctic municipalities — districts and settlements. The obtained estimates are proposed to be used in the development of management decisions that could become the basis of a comprehensive interdepartmental inter-municipal program for the socio-economic development of Arctic municipalities.

Published: April 2022

The Russian Arctic has been attracting a growing interest in terms of research and management. The former is due to the lack of knowledge about current processes in its development in the rapidly changing internal and external environments, and the latter is driven by the rising significance of this macroregion in ensuring the country’s economic, ecological, geopolitical stability, and national security. Being inter-dependent, these interest spheres evidence the demand for the study of Arctic regions, especially newly established ones, and underlie its practical value, which consists in building the analytical foundations for working out and implementing the administrative mechanisms for socio-economic space integration in Arctic regions. Hence, the aim of this study is to define the strategic development priorities for the regional socio-economic system of the Karelian Arctic as a newly established region in the context of the multifarious Russian Arctic integration processes. This aim is achieved through the following tasks: analysis of the strengths and weaknesses of the socio-economic system of the Karelian Arctic, identification of key challenges and opportunities for its development, identification of the strategic priorities to overcome threats and realize opportunities. The principal methods were expert and in-depth interviews, SWOT analysis and content analysis, the dialectic method and system approach, which were applied in the context of the propositions of spatial economics. As a result of the study, characteristics of the Karelian Arctic’s socio-economic system are identified in the context of the high-relevance problems of managing the development of the Arctic macroregion as a complex system. Directions for further research are defined, with the aim to build the scientific foundations for managing the spatial development of the Russian Arctic zone and its constituent regions and for handling the challenges hindering such development.

The considered scientific works of foreign and domestic scientists made it possible to determine the methodology for rational assessment of the resource potential of the industry of the Arctic territories. The study was performed on the basis of production, technical, investment, staffing and innovation development indicators for 2013–2019. The study showed that in terms of production and technical indicators the Arctic regions generally have an average level of resource potential while the maximum values are typical for the Nenets and Yamalo-Nenets Autonomous Okrugs. In terms of investment indicators, the Arctic regions are characterized by high potential. In terms of staffing, the Arctic regions are characterized by low potential while Murmansk Oblast demonstrated effective personnel policy. Innovation development indicators of the Nenets Autonomous Okrug and the Murmansk Oblast are lower than in the Chukotka and Yamalo-Nenets Autonomous Okrugs. The Arctic regions are characterized by the differentiation of indicators of resource provision of economic development associated with differences in production, investment, personnel and innovation spheres. The study showed that the highest aggregate resource potential for innovation development is typical for the Yamalo-Nenets Autonomous Okrug while the lowest one is typical for the Chukotka Autonomous Okrug and the Murmansk Oblast. Proposals for further scientific research in the direction of enhancing innovation and accordingly increasing socio-economic indicators of the Arctic regions were developed.

Published: April 2022

Mineral fillers provide a significant role in the Marshall properties of hot mix asphalt for paving applications. The article's goal is to assess the suitability and effectiveness of two minerals (coal dust and wood powder ash) used as fillers in asphalt concrete. Chemical composition test using X-ray fluorescence indicated a high content of SiO2, Fe2O3, and Al2O3, which encouraged us to select the coal dust and wood powder ash as mineral fillers for further investigation. A total of 90 cylindrical Marshall Specimens, made with different percentages (i.e., 4%-8%) of coal dust, wood powder ash, and conventional stone dust filler were prepared to assess the performance of individual filler within the asphalt concrete mix. And after that, volumetric characteristics such as density, stability-flow test, air void, and voids in mineral aggregates have been analyzed to evaluate the effectiveness of every sample and, afterward, to find out the optimum asphalt content. Finally, the optimum asphalt content for every filler material was ascertained, and subsequently, Marshall properties were checked again to assess the optimum filler content in the mix that satisfy all the standard criteria. The overall Marshall properties for both fillers were within the acceptable limits. Though the optimum asphalt content was higher for coal dust than wood powder ash and stone dust, the wood powder ash showed better durability than coal dust. All mixtures have been found to have better resistance to deformation, fatigue, and moisture-induced damages; however, 4% coal dust and 6% wood powder ash satisfied most of the Marshall criteria than other percentages.

Published: April 2022

The long arc and high-quality astrometric measurements of outer irregular satellites are prerequisites for improving their orbital theories and increasing the precision of their ephemerides. In order to obtain good astrometric positions of Himalia, the largest irregular satellite of Jupiter, we have processed and reduced 911 ground-based CCD frames obtained between 2015 and 2021 by three telescopes (including 1 and 2.4 m telescopes at Yunnan Observatory, and 0.8 m telescope at Purple Mountain Observatory) over 61 nights. Subtracting off the companion star of our target by constructing an effective point-spread function (ePSF) model in some CCD frames, the ePSF-subtracted technique is used to reduce the centering error. Some additional techniques are applied in data reduction to further improve positional accuracy and precision of Himalia. This includes geometric distortion correction, weighted polynomial plate models, and the precision-premium effect, since their relative positional measurements have better precision when two objects are very near (e.g., less than 60″). The star catalog Gaia DR2 is used for astrometric calibration, and theoretical positions of Himalia are retrieved from JPL Horizons ephemeris, including the satellite ephemeris Jup344 and the newest planetary ephemeris DE441. Our results show the mean (O − C)s (observed minus computed) of the positional residuals of Himalia are −0."004 and 0.″005 in R.A. and decl., respectively, and their corresponding standard deviations are about 0.″020 in each direction.
The Accurate Mass Distribution of M87, the Giant Galaxy with Imaged Shadow of Its Supermassive Black Hole, as a Portal to New Physics
Authors: De Laurentis Mariafelicia , Salucci Paolo
Published: April 2022

The very careful Event Horizon Telescope estimate of the mass of the supermassive black hole at the center of the giant cD galaxy M87, allied with recent high-quality photometric and spectroscopic measurements, yields a proper dark/luminous mass decomposition from the galaxy center to its virial radius. That provides us with decisive information on crucial cosmological and astrophysical issues. The dark and the standard matter distributions in a wide first time detected galaxy region under the supermassive black hole gravitational control. The well-known supermassive black hole mass versus stellar dispersion velocity relationship at the highest galaxy masses implies an exotic growth of the former. This may be the first case in which one can argue that the supermassive black hole mass growth was also contributed by the dark matter component. A huge dark matter halo core in a galaxy with inefficient baryonic feedback is present and consequently constrains the nature of the dark halo particles. The unexplained entanglement between dark/luminous structural properties, already emerged in disk systems, also appears.

Published: April 2022

Background: Chemical agents such as streptozotocin (STZ) and nicotinamide (NAD) are used in animal models of diabetes mellitus and their related consequences in the kidneys. Several studies have been conducted to determine the modeling, however, the results are still unclear. Moreover, diabetic nephropathy is considered to begin with an inflammatory reaction in the kidneys.  Objectives: This study aims to investigate the metabolic profile STZ and NAD induce inflammation in the kidney.  Methods: The male Wistar rats used were divided into control and STZ-induced diabetes. Half of the diabetes group received a single dose of nicotinamide (230 mg/Kg) 15 minutes after STZ injection and all groups were monitored for 6 weeks. Furthermore, the profiles of creatinine, urea, and uric acid from serum and urine were observed and the kidney inflammation was tested by immunohistochemistry (IHC) with IL-6 and TNF-α parameters.  Results: The result shows that the administration of a single dose of 230 mg/kg NAD in diabetic rats induced with 50 mg/kg and 65 mg/kg STZ affects body weight and kidney organ index. For 6 weeks of testing, both doses of STZ were enhanced several parameters of kidney damage in diabetic rats in blood and urine chemical parameters. Furthermore, the use of NAD to promote inflammation in STZ-induced diabetic rats gave no significant difference. However, NAD can help mice live longer and avoid problems throughout the test.  Conclusions: The use of NAD leads to inflammation in Streptozotocin-induced diabetic rats. Therefore, the administration of Nicotinamide is recommended since it helps the rats live longer during the experiment.

Published: April 2022

BACKGROUND: The coronavirus disease-19 (COVID-19) pandemic is of special concern in all parts of the world, including Indonesia. The number of active cases also continues to increase in most provinces in Indonesia, especially in the Special Region of Yogyakarta. This condition requires health workers to collaborate well in suppressing and handling COVID-19 patients.

AIM: The aims of this study were to find out how collaboration occurs between health workers in handling COVID-19. This study identifies opportunities and challenges for Interprofessional Collaboration (IPC) health workers at the Primary Health Center of Bantul Regency.

METHODS: The design of this study was a cross-sectional study. We used the purposive sampling method to recruit participants. This study was followed by 200 participants who were health workers at the Primary Health Center in Bantul Regency. We used a questionnaire as the instrument. The questionnaire consists of four dimensions of IPC such as knowledge, collaboration, service, and the role of a pharmacist. The data obtained were statistically analyzed using Chi-square and Spearman.

RESULTS: The result showed that IPC health worker at Health Primary Center of Bantul was categorized as good (45%). However, IPC at the Health Primary Center is still not optimal. There were top three obstacles in collaborating, namely, lack of time, perception of complicated bureaucracy, and lack of trust from health workers about their knowledge and skill.Based on spearman test p-value for age, gender, education level, years of service, occupation were 0.764; 0,732; 0.808; 0.189; 0.582; 0.746. This result showed that the sociodemographic characteristics of the participants did not significantly affect the IPC (P>0.05).

CONCLUSIONS: The main key in practicing IPC was building a good work team, good communication and relationship, responsibility for each other’s, keep learning from each other and being critical, and maintaining the ethics of each profession. Thus, effective and efficient collaboration will be established.

BACKGROUND: Diabetes mellitus is a metabolic disease associated with unhealthy eating patterns, a lack of physical activity, obesity, smoking habits, and family history. Strobilanthes crispus (SC) contains antioxidant compounds known to exert a hypoglycemic effect during long-term interventions in non-diabetic samples.

AIM: This study sought to determine the effect of administering the extract of SC leaves on the blood glucose levels and blood serum lipid profiles of streptozotocin (STZ)-induced diabetic rats.

METHODS: A total of 30 male Rattus norvegicus rats were divided into control and treatment groups. The control groups consisted of negative (normal rats) and positive controls (diabetic rats), whereas the treatment groups consisted of diabetic rats administered with 3.2% and 16.8% SC leaf extract, and glibenclamide as the drug comparison groups. Blood samples were collected from the rats’ retro-orbital vein for the purposes of glucose level and lipid profile measurement before and after the induction of diabetes with STZ as well as 14 days after the intervention. The collected data were analyzed statistically by means of a one-way analysis of variance continued with Duncan’s multiple range test.

RESULTS: The results showed the rats to be hyperglycemic experienced changes in their lipid profiles following the induction of diabetes. The administration of 3.2% SC leaf extract for 14 days reduced the rats’ blood glucose levels, while the effect of the 16.8% SC leaf extract was more pronounced in terms of reducing the rats’ blood glucose levels and improving their lipid profiles (reducing the triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels, while increasing the high-density lipoprotein cholesterol levels).

CONCLUSIONS: This study found 16.8% SC leaf extract to exert a good hypoglycemic effect and leads to an improvement in the lipid profiles in diabetic rats.

Published: April 2022

BACKGROUND: Staple foods as a source of carbohydrates contribute most of human energy needs. Based on Perkeni’s recommendation, diabetic patients can consume at least 45–60% of carbohydrate sources. In addition, several previous studies have shown that increasing the adequacy of dietary fiber above 20–25 g/day can improve glycemic control.

AIM: Our scoping review investigated the potential of Indonesian food sources, namely, sorghum and corn as a source of carbohydrates and also fiber as a substitute rice for diabetic patients.

METHODS: We systematically used electronic databases searched such as PubMed, Science Direct, Web of Science, Portal Garuda, Sinta Ristekbrin, and Google Scholar. We choose the relevant documents used experimental animals and humans’ studies then published between 2011 and 2021.

RESULTS: In total, 17 relevant articles discuss the relationship between giving corn or sorghum with blood glucose levels of animal studies and human. Some studies showed that the effect of eating sorghum or its derivatives can reduce blood glucose. As well as, the other articles indicated eating corn or its derivatives also decrease glycemic response of healthy people and experimental animals. Corn and sorghum contain dietary fiber in the form of resistant starch and have low glycemic index compare with white rice. Furthermore, corn also contains essential fat, mineral, β-Carotene, and isoflavone, while sorghum also includes phenolic components such as phenolic acids and flavonoids.

CONCLUSIONS: Sorghum and corn have the potential as an alternative staple food to achieve a better glycemic response in diabetic patients.

Background/Aims: Renal recovery of a kidney donor after undergoing nephrectomy though challenging is essential. We aimed to examine the effect of estimated glomerular filtration rate (eGFR) percent change at 1-month post-donation on insufficient kidney function after kidney donation.Methods: A total of 3,952 living kidney donors who underwent donor nephrectomy from 1982 to 2019 from eight different tertiary hospitals in Korea were initially screened. Percent changes in the eGFR from baseline to 1-month post-donation were calculated. The degree of percent changes was categorized by quartile, and the 1st quartile was regarded as the group with the lowest decreased eGFR at 1-month after donation. The remaining eGFR less than 60 mL/min/1.73 m2 was the end-point. The Cox proportional hazard model was used for evaluating the impact of initial eGFR and eGFR percent change at 1-month post-donation on the condition with remaining eGFR < 60 mL/ min/1.73 m2. In the multivariate analysis, we used variables with a p < 0.1 in the univariate analysis.Results: A total of 1,585 donors were included in the analysis. During 62.2 ± 49.3 months, 13.7% of donors showed renal insufficiency. The 4th (adjusted hazard ratio [aHR], 10.41; 95% confidence interval [CI], 5.15 to 21.04) and the 3rd (aHR, 4.29; 95% CI, 2.15 to 8.56) quartiles of percent change in eGFR and the pre-donation eGFR (aHR, 0.90; 95% CI, 0.88 to 0.92) were associated with the development of renal insufficiency.Conclusions: The impact of worse initial renal recovery on renal insufficiency was pronounced in donors with lower pre-donation eGFRs. Additionally, worse initial renal recovery of remaining kidney affected the long-term development of renal insufficiency in kidney donors.
Le renversement des rôles : un « reflet » plutôt négligé de l’héritage du passé
Authors: Borgogno Franco , Vigna-Taglianti Massimo , Angelini Rota Antonella
Published: April 2022

Les auteurs explorent, du point de vue théorique et clinique, le phénomène du renversement des rôles, une forme particulière de répétition transférentielle – plutôt négligée par notre littérature – qui peut se représenter de manière plus ou moins continue sur le scénario analytique à travers l’identification inconsciente du patient aux défenses et à la culture psychique du parent, avec une dissociation concomitante d’aspects souffrants de son Soi infantile dans l’analyste. Deux brèves vignettes cliniques illustrent quelques-unes des modalités avec lesquelles ce processus inter/intrapsychique est mis en œuvre dans l’« onde longue » du traitement analytique, et la nécessaire « inter- acting cure  » qui en découle pour amener le patient à accéder à « son cœur dissocié », et favoriser « la cicatrisation de ses blessures psychiques » et l’entrée dans l’univers symbolique partagé.
Les berceuses et enfantines : entre tradition et soin
Authors: Barraco Marthe , Gane Hélène
Published: April 2022

À partir de l’analyse de quelques récits chantés des berceuses traditionnelles et de vignettes tirées de leur clinique en pédopsychiatrie, les auteures décrivent les effets de la pratique des berceuses et des enfantines. Elles montrent comment ce jeu corporel et vocal donné au bébé, quand il est ranimé entre parents et enfants désaccordés, apporte des bénéfices. Il participe ainsi à vivifier les interactions, à construire un attachement de meilleure qualité, il ouvre le bébé à la culture ambiante, il suscite des intégrations somato-psychiques et conforte le démarrage de la construction identitaire chez le tout petit enfant.
Le temps du conte dans la thérapie post-traumatique
Authors: de Bérail Brune
Published: April 2022

Au confluent de la narratologie et de la psychologie, le concept de narrativité est un outil thérapeutique primordial. Dans le cadre de thérapies post-traumatiques, le thérapeute est l’interlocuteur dont l’écoute soutient les fonctions de l’enveloppe narrative du patient : cette élaboration qui transforme les éléments bruts d’un réel effractant en éléments pensables puise dans la vie fantasmatique qui préexistait à l’événement traumatique. Ces « mythèmes » organisateurs sont venus nourrir la structuration de ces contes à usage privé qui se construisent dans le cadre de la thérapie. Mais ce travail engage un jeu particulier où les identités du témoin, de la victime et du coupable sont floues. Patient et thérapeute se retrouvent au coeur d’une valse-hésitation d’identifications projectives qu’il est nécessaire d’analyser.
Un monde en développement de plus en plus inégal
Authors: Lautier Marc , Quenault Béatrice , Gérardin Hubert
Published: April 2022

Les inégalités sont au cœur des processus de développement à l’échelle de la planète. L’article examine les relations inégalités-développement sur la longue période et leurs évolutions quantitatives au fil de l’essor différencié des pays du Nord et du Sud, dans un contexte marqué par la mondialisation des échanges et la globalisation financière, à l’origine de profonds changements dans les chaînes de valeurs et les trajectoires de développement national. Malgré les difficultés d’appréhension des inégalités sociales et environnementales, le plus souvent de natures qualitatives, l’évolution des rapports sociaux et du changement climatique en renforcent l’évidence.
