Published: March 2024

The current study aimed to investigate the chemical composition, antioxidant, antibacterial, and cytotoxic properties of three extracts (hexane, dichloromethane, and methanol) from Cynoglossum tubiflorus. The composition of the methanolic extract was elucidated using HPLC-HESI-MS/MS analysis. The antioxidant effect was examined using NO, DPPH, FRAP, and TAC assays. Antimicrobial activity was evaluated by broth microdilution using various bacterial strains such as S. aureus, S. epidermidis, P. aeruginosa, E. coli, and K. pneumoniae. Structural disruptions in Gram-positive bacteria were visualized using scanning electron microscopy (SEM). Cytotoxic effects were evaluated on human MRC-5 in culture according to the MTT assay. The outcomes suggest that methanol extract contained a high amount of phenolic compounds (254.35 ± 0.360 mg GAE/g DE and 211.59 ± 0.939 mg QE/g DE). By applying the HPLC-HESI-MS/MS analysis, 32 compounds were identified, including phenolic acids, flavonoids, lignans, and fatty acids. This extract showed strong antioxidant (IC50 = 0.043 ± 0.001 mg/mL) and antimicrobial (MIC = 156 µg/mL) activities. The SEM suggests that cells exhibited membrane distortions characterized by surface depressions and alterations in bacterial shape, including dents, when compared to untreated cells. The in vitro cytotoxicity effect on human MRC-5 cells showed no toxicity effects at a concentration of 600 µg/mL. In silico analysis predicted low toxicity for all tested compounds across four different administration routes. This research indicates that this plant could be explored as a powerful source of natural drugs to target pathogens, with applications in the food, pharmaceutical, and medical industries.

Published: March 2024

Serial sectioning and 3D image reconstruction methods were applied to elucidate the structures of the apices of root vascular cylinders (VCs) in taxa of the Poaceae: Zea mays “Honey Bantam”, Z. mays ssp. mexicana, Hordeum vulgare and Oryza sativa. The primary and nodal roots were investigated. Observations were performed using high-quality sectioning and 3D image-processing techniques improved and developed by the authors. We found that a quiescent uniseriate plerome was located at the most distal part of each VC. Vascular initials were located immediately basipetally to the plerome as a specific uniseriate layer that could be classified into central and peripheral initials that produced all the cells in the VC. No supplying of cells from the plerome to the vascular initials was observed. Numerical analysis revealed a “boundary point” along the root axis where the rate of increase of the vascular cell number markedly declined, and the VC diameter, number of vascular cells, and number of late-maturing metaxylem vessels (LMXs) at that point showed a similar relationship among the taxa and the types of roots examined (primary vs. nodal). The plerome and vascular initials layer can be considered independent after seed germination in these taxa. A boundary point at which procambial cell proliferation sharply declined was identified. The diameters of the VCs, number of LMXs, and number of vascular cells at the boundary point were found to be strongly related to each other.

Published: March 2024

Organic poultry sector needs high-quality proteins sources to meet specific requirements. The EU’s organic regulation forbids synthetic amino acids; therefore, soybean, with its balanced essential amino acid content, has become the most used protein source, though much of it is imported from non-EU countries, with sustainability and crop competition issues; therefore, it should be substituted with a high-protein-value alternative such as insect meal. In this study, 900 Aviagen Savanna broilers were fed with three different organic diets: soybean only (S100), 50% black soldier fly larvae meal (BSL) and 50% soybean (BSL50), and 100% BSL only (BSL100). Broiler performance, welfare, and fatty acids (FA) were analyzed. BSL50 and BSL100 negatively affected growth, while only BSL100 worsened all of the market-related performances. Meat showed a significant increase in saturated FA (SFA) (p < 0.000) and a corresponding decrease in polyunsaturated FA (PUFA), in BSL50 and BSL100, but α-linolenic acid was not affected by BSL50 treatment (p < 0.000). The SFA increase could represent a negative aspect for human health (e.g., cardiovascular diseases), but, as reported by other authors, medium chain SFA, (i.e., lauric acid), may show beneficial effects as well (i.e., antibacterial, anti-inflammatory and antioxidant properties).

This study investigates the degradation kinetics of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil using hydrogen peroxide (H2O2) and the Fenton process (H2O2/Fe2+). The effect of oxidant concentration and the Fenton molar ratio on PAH decomposition efficiency is examined. Results reveal that increasing H2O2 concentration above 25 mmol/samples leads to a slight increase in the rate constants for both first- and second-order reactions. The Fenton process demonstrates higher efficiency in PAH degradation compared to H2O2 alone, achieving decomposition yields ranging from 84.7% to 99.9%. pH evolution during the oxidation process influences PAH degradation, with alkaline conditions favoring lower elimination rates. Fourier-transform infrared (FTIR) spectroscopy analysis indicates significant elimination of PAHs after treatment, with both oxidants showing comparable efficacy in complete hydrocarbon degradation. The mechanisms of PAH degradation by H2O2 and the Fenton process involve hydroxyl radical formation, with the latter exhibiting greater efficiency due to Fe2+ catalysis. Gaussian process regression (GPR) modeling accurately predicts reduced concentration, with optimized ARD-Exponential kernel function demonstrating superior performance. The Improved Grey Wolf Optimizer algorithm facilitates optimization of reaction conditions, yielding a high degree of agreement between experimental and predicted values. A MATLAB 2022b interface is developed for efficient optimization and prediction of C/C0, a critical parameter in PAH degradation studies. This integrated approach offers insights into optimizing the efficiency of oxidant-based PAH remediation techniques, with potential applications in contaminated soil remediation.

Authors: Kuang Yingfeng , Chen Xiaolong , Zhu Chun
Published: March 2024

The objective of this inquiry is to illuminate the attributes of heavy metal contamination and evaluate the potential ecological hazards inherent in the surface soil of Chenzhou City. A comprehensive analysis was conducted on 600 systematically collected soil samples within the study area, utilizing enrichment factors, geo-accumulation indices, comprehensive pollution indices, potential ecological hazard indices, and health risk assessment models to evaluate the degree of heavy metal contamination in the soil, potential ecological risks, and associated health hazards. The findings reveal that the average enrichment factor (EF) for each heavy metal is below 2, with the hierarchy from highest to lowest being Hg > Cd > Cu > Pb > Ni > Zn > Cr > As. Approximately 78.67% of soil samples exhibit no pollution to weak pollution levels based on heavy metal enrichment factors. Moreover, the comprehensive pollution index (IPIN) indicates that 95.17% of soil samples are within safe and pollution-free levels, indicating an overall environmentally secure setting. However, 2.67% of samples display heightened potential ecological risk levels, primarily concentrated in the southwestern region of the study area, influenced by nearby industrial activities. Additionally, it is noteworthy that both the non-carcinogenic and carcinogenic health hazards emanating from soil heavy metals to adult individuals lie within tolerable thresholds. Among these, arsenic (As), chromium (Cr), and lead (Pb) have been discerned as the principal non-carcinogenic agents. It is of particular significance that only a solitary soil specimen, located in the southwestern quadrant of the investigative region, manifests detectable health perils for children.

Published: March 2024

People living alone encounter well-being challenges due to unnoticed personal situations. Thus, it is essential to monitor their activities and encourage them to adopt healthy lifestyle habits without imposing a mental burden, aiming to enhance their overall well-being. To realize such a support system, its components should be simple and loosely coupled to handle various internet of things (IoT)-based smart home applications. In this study, we propose an exercise promotion system for individuals living alone to encourage them to adopt good lifestyle habits. The system comprises autonomous IoT devices as agents and is realized using an agent-oriented IoT architecture. It estimates user activity via sensors and offers exercise advice based on recognized conditions, surroundings, and preferences. The proposed system accepts user feedback to improve status estimation accuracy and offers better advice. The proposed system was evaluated from three perspectives through experiments with subjects. Initially, we demonstrated the system’s operation through agent cooperation. Then, we showed it adapts to user preferences within two weeks. Third, the users expressed satisfaction with the detection accuracy regarding their stay-at-home status and the relevance of the advice provided. They were also motivated to engage in exercise based on a subjective evaluation, as indicated by preliminary results.

Published: March 2024

The present research describes the development and validation of a self-reported instrument that measures the determinants of pedestrians’ intention to violate traffic rules, based on the theory of planned behaviour. Moreover, the research deals with the analysis of the predictive validity of an extended theoretical framework of the theory of planned behaviour in relation to pedestrians’ intention to violate. Based on the quota sample, adult pedestrian respondents (n = 383) completed a questionnaire assessing the relevant variables. Valid and reliable scales were developed, and they measure subjective, descriptive, normative, and personal norms, cognitive and affective attitudes, perceived behavioural control, habit formation, and behavioural intention concerning pedestrians’ misdemeanour. Hierarchical regression analysis indicated that all components, except descriptive norms, were significant simultaneous predictors of pedestrians’ intention to violate. The most powerful predictor is the personal norm. Overall, the findings considerably support the concept of the extended theoretical framework of the theory of planned behaviour.

Published: March 2024

Responding to changing value creation processes in the sheet metal working sector, where the complexity and interchangeability of products challenge traditional differentiation strategies, this exploratory analysis examines the integration of service-oriented and data-driven business models as new paths to ensure competitiveness, especially for small and medium-sized enterprises (SMEs). This study aims to capture the current state and challenges associated with the implementation of these business models in this sector. This research was conducted through semi-structured interviews with SMEs in the industry. The findings indicate that service-oriented and data-driven business models are not yet widely adopted and that manufacturing companies require support in their implementation. Fields of action were identified for the industry. These are “Creating awareness and understanding”, “Recognizing added value”, “Increasing company maturity”, and “Understanding the change process”. Cooperation between science and industry is essential in tackling these fields of action to ensure the successful integration of such business models in manufacturing companies. This paper identifies challenges in the fields of action that companies must address through a structured approach, promoting awareness, recognizing value, improving organizational maturity, and understanding the change process to successfully implement service-oriented and data-driven business models.
Analysis of Pros and Cons in Using the Water–Energy–Food Nexus Approach to Assess Resource Security: A Review
Authors: Rezaei Kalvani Somayeh , Celico Fulvio
Published: March 2024

The water–energy–food (WEF) nexus is drawing much attention in scholarly literature as a novel alternative to address complex resources and achieve resource security. The aim of this study is to analyze and review existing nexus studies to investigate the current status of nexus research worldwide. This study used a narrative review approach to provide a comprehensive overview on the WEF nexus using a variety of databases. It is indicated that the majority of studies in Asia and Africa focused on the water–energy–food (WEF) nexus. China and Brazil had the largest nexus research. Based on the existing literature, most of attention has been paid to food production. However, food consumption patterns and dietary change are rarely evaluated, and there is a lack of study on impacts of dietary change on the WEF nexus. Moreover, there is a lack of frameworks for the evaluation of the WEF nexus under dietary change scenarios. The major challenge of the nexus approach is data availability in crop production, which can be solved by using remote sensing data. There is a lack of standard and conceptual frameworks for nexus assessment and, then, an essential need to provide a new holistic and standard approach that be applicable worldwide to increase connections between researchers and decision makers, as well as the applicability of nexus approaches. Future research must couple the development of a holistic standard approach with experimental tests in different areas, involving interdisciplinary research groups able to carry out all the experimental activities, the numerical simulations, and the statistical analyses of climatic time series (in a climate change perspective) indispensable to demonstrate the real benefits of using a WEF-derived nexus approach.

Published: March 2024

In the present study, banana pseudo-stem (BS) was pyrolyzed under anaerobic conditions without any physical or chemical modification. Their properties, as well as their sorption affinity to ofloxacin (OFL), were studied. As a result, oxalates and KCl formed at a relatively low temperature of 300 °C, while bicarbonates generally formed at a pyrolysis temperature above 400 °C. Surface functional groups of BS biochars facilitated OFL sorption mainly via specific interactions including electronic attraction (EA), π–π electron donor–acceptor (π–π EDA) interaction, the ordinary hydrogen bond (OHB), and the negative charge-assisted hydrogen bond ((−)CAHB). Except for (−)CAHB, these interactions all decreased with an elevated pH, resulting in overall decreased OFL sorption. Significant OFL sorption by BS biochars produced at 300 °C, observed even at an alkaline condition was attributed to (−)CAHB. Micropores formed in BS biochar prepared at 500 °C, with a specific surface area as high as 390 m2 g−1 after water washing treatment. However, most micropores could not be accessed by OFL molecules due to the size exclusion effect. Additionally, the inherent K-containing salts may hinder OFL sorption by covering the sorption sites or blocking the inner pores of biochars, as well as releasing OH− into the solution. Thus, BS biochar produced at 300 °C is an excellent sorbent for OFL removal due to its high sorption ability and low energy. Our findings indicate that biochar techniques have potential win–win effects in recycling banana waste with low energy and costs, and simultaneously converting them into promising sorbents for the removal of environmental contaminants.

Human Visceral Leishmaniasis is an endemic public health problem in the Amazon. This article analyzed the spatial distribution of this disease and its relationship with socioeconomic, environmental and public health policy variables in four mesoregions of the state of Pará, from 2011 to 2022. This ecological study used secondary data obtained from official Brazilian agencies. Spatial analysis was performed using the Flow, Kernel and Global Moran bivariate techniques expressed in thematic maps. In the mesoregions studied, 2685 cases of the disease were confirmed, with the highest number of cases in Southeast Pará state. The epidemiological profile followed the national pattern of occurrence of the disease, with a higher number of cases in children below school age. Spatial dependence was observed between the prevalence of the disease and socio-economic indicators. The most intense movement of patients was towards the Belém Metropolitan mesoregion. The disease showed an inhomogeneous pattern of distribution of cases, with a direct relationship between areas with cases and deforestation associated with different anthropic activities. There is a socio-environmental production of the disease that goes beyond the border limits of the mesoregions, and its establishment is related to the unsustainable development model implemented in the region.

Natural 4-1BBL (CD137L) is a cell membrane-bound protein critical to the expansion, effector function, and survival of CD8+ T cells. We reported the generation of an active soluble oligomeric construct, SA-4-1BBL, with demonstrated immunoprevention and immunotherapeutic efficacy in various mouse tumor models. Herein, we developed an oncolytic adenovirus (OAd) for the delivery and expression of SA-4-1BBL (OAdSA-4-1BBL) into solid tumors for immunotherapy. SA-4-1BBL protein expressed by this construct produced T-cell proliferation in vitro. OAdSA-4-1BBL decreased cell viability in two mouse lung cancer cell lines, TC-1 and CMT64, but not in the non-cancerous lung MM14.Lu cell line. OAdSA-4-1BBL induced programmed cell death types I and II (apoptosis and autophagy, respectively), and autophagy-mediated adenosine triphosphate (ATP) release was also detected. Intratumoral injection of OAdSA-4-1BBL efficiently expressed the SA-4-1BBL protein in the tumors, resulting in significant tumor suppression in a syngeneic subcutaneous TC-1 mouse lung cancer model. Tumor suppression was associated with a higher frequency of dendritic cells and an increased infiltration of cytotoxic CD8+ T and NK cells into the tumors. Our data suggest that OAdSA-4-1BBL may present an efficacious alternative therapeutic strategy against lung cancer as a standalone construct or in combination with other immunotherapeutic modalities, such as immune checkpoint inhibitors.

Published: March 2024

This study aimed to understand Poles’ attitudes and beliefs towards influenza vaccinations in the flu season of 2022–2023, especially among individuals at risk of flu complications. The cross-sectional survey-based study was carried out on a sample of 810 respondents. The questionnaire was disseminated electronically using social media and e-mail. The majority of respondents (71%) could identify “high-risk groups” recommended for influenza vaccination, and 52.01% of respondents reported receiving influenza vaccination at some point in the past, with 32.12% receiving it in the 2022–2023 flu season and 41.09% in the 2021–2022 season. The majority of respondents declaring acceptance of the vaccine for the 2022–2023 season were in the high-risk group. Only 17.28% of respondents declared receiving both influenza and SARS-CoV-2 vaccines in the 2022–2023 season, with the vast majority being respondents from the “high-risk group” (p < 0.0001). Only 26.12% of respondents declared their intention to continue influenza vaccination in the future. Of those expressing the intention to get vaccinated against the influenza virus in future seasons, 46.79% were from the “high-risk group” (p = 0.0087). Results suggest the need for further interaction and education with healthcare providers and targeted informational efforts for at-risk groups regarding the benefits of flu vaccination.

Published: March 2024

Julia Creek dunnarts are an endangered species of carnivorous marsupials and the focus of multiple conservation strategies involving significant resources such as captive breeding programs. Despite the relevance for conservation, no study to date has focused on evaluating geriatric diseases in dunnarts. This study describes the pathology findings in a group of one wild and thirty-five captive-born, mostly geriatric Julia Creek dunnarts that failed to produce offspring over multiple breeding periods. A total of 20 females and 16 males were submitted for a postmortem examination, with ages ranging from 9 to 42 and 12 to 42 months for females and males, respectively. Of these, 10 had unremarkable findings. The most common condition in females was cystic glandular hyperplasia (n = 8), typical of hormonal dysregulation profiles in senescence, particularly hyperestrogenism. Rarely, cutaneous disease represented by unidentified dermal round cell infiltrates was observed in females (n = 2). Primary reproductive hormonal dysregulation was also suspected in males diagnosed with testicular degeneration, aspermatogenesis and/or atrophy (n = 3). Cutaneous round cell infiltrates, possibly compatible with epitheliotropic lymphomas, were seen in males (n = 3), and 2/3 affected males also had concurrent testicular degeneration or atrophy, indicating male sex could be a predictor for lymphoid neoplasia in aged dunnarts, especially in individuals with concurrent testosterone-luteinizing hormone dysregulation as it occurs in gonadectomized animals. The role of an underlying viral etiology is also explored. This study is the first to describe major spontaneous diseases in endangered aged Julia Creek dunnarts, providing an important understanding of senescence and geriatric diseases within a conservation context.
Fault-Tolerant Controller Applied to a Wind System Using a Doubly Fed Induction Generator

Published: March 2024

Wind systems are sustainable and economical options for producing electrical energy. These systems efficiently manage the power flow by maximizing wind power and consuming reactive power from the grid. In addition, wind systems must maintain operation despite utility grid electrical failure; hence, their control system must not collapse. This study proposes a fault-tolerant converter controller to ensure the efficient operation of wind system converters. The central concept behind this is that when there is an imbalance in the utility grid voltage due to a fault nearby or far away, positive and negative sequence voltages are created in the time domain. Then, two parallel controllers operate to allow the wind system to continue operating despite the failure. One controller utilizes positive sequence voltages as inputs to regulate the generator’s electromagnetic torque. This helps in maximizing the amount of wind energy. The second controller uses negative sequence voltages as inputs, which helps to cancel out the produced torque in the opposite direction, thereby preventing generator overload. Finally, the controllers proposed in this article are validated through simulations, and the results are presented.

The possibilities of the author’s professional development courses “Technologies of Effective Pedagogical Communication, Psychodiagnostics and Provision of Psychological Support to Participants of the Educational Process in Institutions of Professional Pre-Higher Education” for the development of the resilience of economic college teachers in war conditions based on their key competencies, in particular personal, social and educational competence, are considered. The experience of the Poltava Academy of Continuing Education named after M. V. Ostrogradskyi to fulfill the requirement of the Ministry of Education and Culture of Ukraine to ensure that teachers pass advanced training courses to improve their knowledge, skills, and practical skills to provide psychological support to participants in the educational process in wartime conditions is shown.

The article outlines the essence of the following terms: “key competencies” (necessary for the growth of a person’s personal potential and development, expansion of his opportunities for employment, social integration, active citizenship), “personal, social and educational competence” (the ability to be aware of one’s own internal states, effectively manage time and information, work constructively with other people, remain stable and manage one's own education and career), “resilience” (a dynamic, complex, multidimensional set of characteristics personality, its ability to resist and adapt to adverse and traumatic events), “resilience” (the ability of an individual to withstand the difficulties of life, quickly recover, successfully adapt in adverse circumstances, a dynamic personality property that can and should be developed, although it is innate).

Resilience is considered as a) a concept; b) a process; c) a result; and also as a) personality quality (ability to overcome stress); b) a coping process (psychological strategy and method of overcoming a stressful situation); c) adaptive protective mechanism of the individual (allows to adapt after mental trauma or resist stress). The components of the resilience of economic college teachers are determined – adaptability, stability, hope, optimism. The expediency of following the self-help rules and advice for the development of the teacher’s resilience in the conditions of war, which are used in professional development courses, is substantiated.

The methodological principles of conducting professional development courses for the development of economic college teachers’ resilience in the conditions of war based on their key competencies (in particular, personal, social, and educational competence) are singled out. They are the following: a) continuity; b) science; c) visibility; d) objectivity; e) developmental training; f) democratization; g) self-development of the individual; h) psychological support.

The purpose and objectives of the study are to identify and evaluate the impact of Generative Artificial Intelligence (Generative AI) on the labor market of Kazakhstan. To optimize approaches related to determining the possibilities of automating production processes, the authors developed and applied a methodology that allows assessing the possibility of automation not of the profession as a whole, but only of the basic functions performed, characteristic of a particular profession. As a result of the analysis of the professional structure of employment in the Republic of Kazakhstan, the potential for replacing workers with mechanisms, automatic machines, robots, and Generative AI in the context of industries and regions was determined and assessed, and the most and least vulnerable categories of personnel were identified. The authors conclude that the potential for using Generative AI turned out to be significantly wider than could have been previously assumed. Automation of jobs and replacement of workers with mechanisms Generative AI (according to forecasts - from 33% to 36%) will begin primarily in organizations and enterprises of large cities, as well as industrialized regions. However, for several objective reasons, one should not expect rapid changes. According to forecasts based on the results of the study, this process will take over smoothly, as companies see this as a way to increase profits.

The purpose of the study is to fill the gap in studying the practice of developing consumer budgets in Soviet Russia and the USSR, generalizing, analyzing, and systematizing the experience of developing consumer budgets in 1918–1928 and 1956–1991. The concepts of consumer budgets used in these periods are considered and the areas of their application are grouped. Particular attention is paid to the methods used for developing consumer budgets, including normative. The research methods are dialectical knowledge, bibliographic and historical research (comparative, periodization, retrospective), classifications, groupings, etc. The authors conclude about the continuity of the experience of Soviet Russia and the USSR in the development and application of consumer budgets in the conditions of modern Russia after 1991 and the feasibility of its use by federal and regional executive authorities at present when preparing decisions related to the further development of the system of consumer budgets and programs to reduce poverty.
Beckett et Bion

Beckett and Bion.

Beckett underwent psychoanalysis for two years (1934-35) with Bion in London before emigrating to Paris where he began, in French, his most significant literary work as a writer of fiction. The author of this article explores Beckett’s works for the trace of his interrupted psychoanalytical experience, and more particularly for the transposition of the psychonalytical situation and the working through of negative transference.

Furthermore, it can be seen that Beckett’s heroes and narrators often anticipate ideas and formulae which can later be found in Bion. The author thus reaches the hypothesis that Bion was profoundly implicated in the psychoanalysis of Beckett, in whom found several of his characteristics (cynicism, aloofness, depression). Bion and Beckett probably represented for each other, mutually, the secret imaginary twin.
Lieux communs de l’élaboration plurielle du contre-transfert en situation de groupe
Authors: Vidal Jean-Pierre
Published: March 2024

Common places of the plural elaboration of the counter-transference in groupal circonstances.

The question is, for the author; to drax metapsychological inferences inscribed in the upsetting reality of the counter-transference, both as an experience (this one which reveals the partial settlement of the other in oneself) and as a concept. This one implies a common psychical space of which condions of possibility lie in the refusal, from now on, of considerering the psyche as a close and individed entity. Bot, if this one’s limits are comparatively indecided and pervious it is owing to her actual nature. Consequence of her own division (that is to say of her essential groupa-lity) she must be understood as an inside out side (inner exteriority). It results prom this, an original ability to form associating connections an to build «dissubjectivated» psychical spaces perfect common places of which we pind the spatial analogy in these created (elected) spaces for meeting and working. These externalized spaces of a groupal psychical topography would be both the wittnesses and the revealer of it. We should not consider them as neutral and insignificant; in this respect, they are the soitable places for the counter-transferencial analysis as plural elaboration, when the opportunity occurs, for those of the «intertranferencial analysis».
Un groupe thérapeutique pour «deuils spéciaux». Le problème du savoir

A therapeutic group for «special mourning». The problem of knowledge

Group therapeutic space allows us to recognise the effect of social violence exercised by State terrorism. We are studying the repercussions on exchanges within groups and in the individual psyche of each of its members. We have focussed on the process of mourning, the permeability between social context and the group , the transformation of panic and the reflection of induction methods within the social context, as well as knowledge and the mental significance of disappearance.
De l’influence de la frontière dans les orientations et la pratique de la psychanalyse roussillonnaise. Des analystes en groupe... au travail psychanalytique groupal
Authors: Vidal Jean-Pierre
Published: March 2024

A partir d’une réflexion, à la fois critique et psychanalytique, sur r histoire particulière d’un groupe de psychanalystes associés pour faire de la psychanalyse en groupe, l’auteur se demande comment et pourquoi on devient psychanalyste de groupe. Où s’ origine et se fonde ce mouvement qui conduit des individus à se rassembler pour faire en groupe, entre eux et avec d’autres, un travail psychanalytique groupal, pour penser ce travail, aussi, en vue de ï élaboration théorique de leur pratique ? Au-delà des déterminations personnelles inscrites dans l’ histoire singulière de chacun qui peuvent pousser tel ou tel à investir le groupe, à s’investir dans le groupe et dans le travail psychanalytique à son sujet, il y a lieu de se demander s’il n’existe pas des situations, des expériences communes ou équivalentes susceptibles de mobiliser ou induire un identique processus de recherche du groupe, un même souci d’ appartenance à un groupe. L’auteur fait l'hypothèse, à ce sujet, qu’une manière originale de vivre la «frontière» dans la totalité de son expérience personnelle n’est peut-être pas sans rapport avec cette passion en relation avec sa propre groupalité, ses appartenances multiples, ses références plurielles, sa marginalité, ses déportements, ses transgressions..., ses filiations freudiennes et les origines groupales de la psychanalyse.

De quelques hypothèses sur les causes «rémanentes» de la violence familiale. Les avatars de l’angoisse génétique
Authors: Vidal Jean-Pierre

Concerning several hypotheses on the recurrent causes of family violence — The avatars of genetic anguish

The psychical organisers of «groupness» in its nascent form appear to fulfill the function of assuring protection and reassurance against the disturbing effects provoked by encounters. The closer and more intimate the relationship, the greater is the worry, anguish and finally reactive violence released because of proximity or promiscuity. In this sense, family violence is the scene of the most profound insecurity.

The psychical organisers, such as those that Bion defines as Basic Hypotheses (to take an example), demonstrate a contention of this violence and can thus be considered as elementary defensive processes. Since institutions define the positions, roles, attitudes and specific behaviour of their members as well as the nature and the quality of their reciprocal exchanges, couldn’t they be considered to be the institutionalisation of the defensive processes of social life in its fluid state ?

As a result, any harm caused, for example, to the institution of the family in so far as its organisation tends to define, for the sake of its members, their respective places or functions, creating in this way a feeling of relative security, will necessarily release considerable anguish and violence, instead of containing them in conformity with its initial function.

This hypothesis is sustained by a reflection on the manifestations of genetic anguish (persecutive and depressive ) and the different defensive strategies elabored as a remedy. One can suppose that when these dispositions for a modus vivendi, which are initially instituted by the Basic Presuppositions, become altered or feeble, the logical consequence is a general state of anomia which generates a type of violence of which the Greek myths are not only the expression (in the form of phantasies) but also the direct witness and reflection.
Séduction et traumatisme : les formes élémentaires de la sexualité dans les groupes
Authors: Kaës René

Seduction and Trauma : Elementary Forms of Sexuality in Groups

Elementary forms of sexuality in groups have scarcely ever been taken into consideration. Thus, a preliminary base to any psychoanalytic comprehension of psychic reality in the inter-subjective group space and in the formation of the subject of the group is missing : after recalling Freud's theses, the effects of instinctual co-excitation, seduction, and mastery are taken up this perspective.
