3D printable model of an entomological pinning block, designed for precise positioning of entomological glue boards and labels
Authors: Gjonov Ilia , Hristozov Andrey
Published: March 2024

The entomological pinning block is a device widely used by entomologists to facilitate the mounting of glue boards and labels on entomological pins. The most commonly used entomological blocks are wooden blocks with steps of varying heights, allowing the placement of individual glue boards and labels at different levels. Models of entomological blocks ready for 3D printing are scarce on the Internet. The proposed model of an entomological block is ready for printing on a standard 3D printer. In addition to the usual positioning of glue boards and labels along the Z-axis, the model also offers targeting devices that enable precise positioning of the entomological pin along the X- and Y-axes. The proposed model can be easily modified for use with glue boards or labels of a different width than proposed or with label level steps of varying heights along the pin. The design of the new pinning block is simple, yet effective, making it an accessible and useful tool for entomologists, museum curators and amateur collectors.
Is Garra rezai (Teleostei, Cyprinidae) a species known only from two widely disjunct areas in the Tigris drainage?
Authors: Kaya Cüneyt , Imre Haydar Birol , Kurtul Irmak
Published: March 2024

Garra rezai was recently described from two geographically distant areas in the Tigris drainage: upper Yanarsu River (eastern Türkiye) and Bouein-Sofla Creek (Iran). In the scope of this study, we aimed to ascertain the distribution ranges of G. rezai and its morphologically most similar congener G. rufa in Türkiye by examining 1165 specimens from 73 lots, which were collected between 1957 and 2023 and currently curated in two broad fish collections. To achieve this, we focused on two important diagnostic morphological characters which distinguish these two species: scales on predorsal mid-line between dorsal-fin origin and nape, and branched dorsal-fin rays. The results revealed that G. rufa is a widely distributed species in the Tigris-Euphrates catchment, while G. rezai is regionally widespread, with populations identified in at least six different regions within the Tigris catchment. Additionally, G. rezai is documented for the first time in the upper Euphrates. Furthermore, we identified the drainage areas where G. rezai co-exists with G. rufa.

An efficient data-driven approximation to the stochastic differential equations with non-global Lipschitz coefficient and multiplicative noise
Authors: Qi Xiao , Duan Tianyao , Guo Huan
Published: March 2024

This paper studied the numerical approximation of the stochastic differential equations driven by non-global Lipschitz drift coefficient and multiplicative noise. An efficient data-driven method, called extended continuous latent process flow, was proposed for the underlying problem. Compared with the piecewise construction of a variational posterior process used in the classical continuous latent process flow developed by Deng et al. [13], the principle idea of our method was to derive a variational lower bound by constructing a posterior latent process conditional on all information over the whole time interval to maximize the log-likelihood generated by the observations, which reduces the computational cost and, thus, provides a convenient way to approximate the considered equation. Particularly, our new method showed a better approximation to the underlying equation than the classical drift-$ \theta $ discretization scheme through numerical error comparison. Numerical experiments were finally reported to demonstrate the effectiveness and generalization performance of the proposed method.
Queueing system with batch arrival of heterogeneous orders, flexible limited processor sharing and dynamical change of priorities
Authors: Dudin Alexander , Dudin Sergey , Manzo Rosanna , Rarità Luigi
Published: March 2024

A queueing system with the discipline of flexible limited sharing of the server is considered. This discipline assumes the admission, for a simultaneous service, of only a finite number of orders, as well as the use of a reduced service rate when the bandwidth required by the admitted orders is less than the total bandwidth of the server. The orders arrive following a batch-marked Markov arrival process, which is a generalization of the well-known $ MAP $ (Markov arrival process) to the cases of heterogeneous orders and batch arrivals. The orders of different types have different preemptive priorities. The possibility of an increase or a decrease in order priority during the service is suggested to be an effective mechanism to prevent long processing orders from being pushed out of service by just-arrived higher-priority orders. Under a fixed priority scheme and a mechanism of dynamic change of the priorities, the stationary analysis of this queueing system is implemented by considering a suitable multidimensional continuous-time Markov chain with a generator that has an upper Hessenberg structure. The possibility of the optimal restriction on the number of simultaneously serviced orders is numerically demonstrated.
Mechanistic modeling of alarm signaling in seed-harvester ants
Authors: Lin Michael R. , Guo Xiaohui , Azizi Asma , Fewell Jennifer H. , Milner Fabio
Published: March 2024

Ant colonies demonstrate a finely tuned alarm response to potential threats, offering a uniquely manageable empirical setting for exploring adaptive information diffusion within groups. To effectively address potential dangers, a social group must swiftly communicate the threat throughout the collective while conserving energy in the event that the threat is unfounded. Through a combination of modeling, simulation, and empirical observations of alarm spread and damping patterns, we identified the behavioral rules governing this adaptive response. Experimental trials involving alarmed ant workers (Pogonomyrmex californicus) released into a tranquil group of nestmates revealed a consistent pattern of rapid alarm propagation followed by a comparatively extended decay period [1]. The experiments in [1] showed that individual ants exhibiting alarm behavior increased their movement speed, with variations in response to alarm stimuli, particularly during the peak of the reaction. We used the data in [1] to investigate whether these observed characteristics alone could account for the swift mobility increase and gradual decay of alarm excitement. Our self-propelled particle model incorporated a switch-like mechanism for ants' response to alarm signals and individual variations in the intensity of speed increased after encountering these signals. This study aligned with the established hypothesis that individual ants possess cognitive abilities to process and disseminate information, contributing to collective cognition within the colony (see [2] and the references therein). The elements examined in this research support this hypothesis by reproducing statistical features of the empirical speed distribution across various parameter values.

Published: March 2024

La evaluación de la influencia del COVID-19 en la violencia sobre la mujer es un tema de investigación internacional actual. Algunos países, como España, requieren especial interés por las particularidades de las medidas establecidas en respuesta a la pandemia. Este trabajo analiza la evolución de las llamadas al 016 como un indicador de las tensiones y violencias sobre la mujer. Se utilizan los datos anuales y mensuales desde 2008 hasta 2021, sobre las que se aplican diferentes metodologías como t-test, análisis de regresión e interrupted time-serie analysis. Los resultados de este trabajo indican que en España hubo, en términos generales, un incremento de las llamadas de teléfono al 016 desde la llegada del COVID-19. Sin embargo, existe una gran variabilidad en las llamadas según la situación social y las medidas restrictivas, que hace difícil atribuir este incremento a un efecto a corto plazo o cambio de tendencia.
“Los Argentinos”: A Gang of Swindlers and the Criminal Integration of the Americas, 1935-1943’
Authors: Esteva Diego Pulido
Published: March 2024

This article analyses the cross-border execution of the crime of fraud, which was rife across the American continent during the interwar period. In the early decades of the twentieth century, Mexico had become a major hub for fraud following a boom in this type of crime across the South American Atlantic region. Focussing on a gang of swindlers known as “Los Argentinos”, cosmopolitan travelling criminals, the article investigates the growth of so-called “tricksterism” and the cross-border nature of crimes of fraud and forgery. It concludes that “tricksterism” benefited from both flows of migrants and cross-border connections, eventually building webs of complicity with local, state and federal authorities.

Published: March 2024

Temos como pressuposto que as recentes produções de informações digitais e tecnológicas do fim do século XX e do início do século XXI, aliadas aos avanços da biologia molecular, criam uma nova economia e política dos signos, assim como, novas possibilidades de construção de sujeitos e modos de governo. Há nesse movimento, a configuração de uma nova biopolítica em que os seres humanos têm sido produzidos em meio às suas capacidades de absorção nessas linguagens, promovendo armazenamentos e projeção de vida por meio de algoritmos e linguagem biomolecular. Nesses modos de produção da subjetividade, o ‘eu’ é transmutado em um ‘perfil’, forjado enquanto objeto de governamentalidade. Diante disso, consideramos que tais processos produzem possibilidades ontológicas e de governo, alicerçadas nos atuais modos de produção de informações sobre a sociedade e indivíduos, balizadas, sobretudo, por informações digitais e biomoleculares em práticas de algoritmização da vida no interior do capitalismo contemporâneo.

Incorporating Consumer Behaviour Into the Environmental Appraisal of Eco-Packaging
Authors: Kaur Uttam , Siddhey Prashant Kumar
Published: March 2024

In the packaging industry, where customer behaviours at the end of life are critical to the success of environmentally friendly plans, the incorporation of customer behavioural data is particularly pertinent. To improve the analysis and creation of environmentally friendly packaging, this research investigation investigates the integration of behavioural insights from customer behaviour sciences (such as psychology, sociology, and socio-technical techniques) into life cycle assessment (LCA). The findings show that research on LCA on packaging is typically predicated on theories about customer behaviour, which lessens the usefulness of these studies to assist with sustainable decisions. Nowadays, scenario and sensitivity analysis are the primary techniques used to incorporate behaviour variability. Two key areas in which customer behaviour sciences insights might benefit life cycle assessment (LCA) research are the definition of customer profiles and the modelling of socio-technical characteristics.
Community Detection on Social Networks With Sentimental Interaction
Authors: Feng Bingdao , Cheng Fangyu , Liu Yanfei , Chang Xinglong , Wang Xiaobao , Jin Di
Published: March 2024

Many studies on community detection are mainly based on the similarity in friendship between users. Recent studies have started to explore node contents to identify semantically meaningful communities. However, the sentimental interaction information which plays an important role in community detection is often ignored. By analyzing and utilizing the abundant sentimental interaction information, one can not only more precisely identify the communities, but also discover the interesting interactions and conflicts between these communities. Based on this concept, the authors propose a new Community Sentiment Diffusion Detection Model (CSDD), which utilizes sentimental information embedded in forward posts. Furthermore, the authors present an efficient variational algorithm for model inference. The community detection results have been verified on two large Twitter datasets. It is experimentally demonstrated that we can provide a fine-grained view of sentimental interaction between communities and discover the mechanism of sentiment diffusion between communities.
Resolvent Based Hilbert Transform
Authors: Kuwata Seiichi
Published: March 2024

To perform the Hilbert transformHilof a non-integrable functionφ, such asφ(x) = 1,x, in a numerical calculation-friendly way, we propose a method of rewritingHilin terms of the resolvent for a differential operatorRwhose eigenfunctions satisfy the orthogonality and the completeness, so that the resolvent kernel 〈x|R-1y〉can be given by the eigenfunction expansion. We deal with two cases for the choice ofR: one is the harmonic oscillator Hamiltonian, which is commutative with the Fourier transformF; and the other is such that is commutative withHilitself. We show how the calculation ofHilφis made in a numerical calculation-friendly way, to find that Πk=0,1Hilfk(fk(x) =xk) satisfies quite a simple relation.
Flight Simulation of a Hybrid Electric Propulsion VTOL UAV for Mission Performance Assessment
Authors: Benmoussa Amine , Gamboa Pedro Vieira
Published: March 2024

Hybrid Electric Propulsion Systems (HEPS) have grown to be a promising topic of research for Unmanned Aerial Vehicles (UAVs) applications as they combine the complimentary benefits of internal combustion engine and electric propulsion systems while reducing pollutant emissions. Controlling UAVs in any flight condition is essential for its successful application in practical missions. In general, hybrid-electric UAVs exhibit three flight modes: vertical flight mode, fixed-wing mode and transition mode. The transition control design from vertical and hover flights to fixed-wing flight mode or vice versa still remains a challenge due to the multiple nonlinearities in the model and the optimal design results have a strong effect on mission performance. In the present study, a numerical model was developed to enhance the flight performance and the transition control of a hybrid electric multi-rotor UAV during a specific flight mission. This model is based on the control of forward thrust, lift thrust, and pitch angle to achieve the speed, altitude, and position defined in the mission profile of the flight simulation. The simulation results show that, of the two applied control strategies, the one that separates the segment into one below stall speed and another above stall speed provides better performance and faster response during transition from vertical flight mode (VTOL) to horizontal fight mode (fixed-wing) and vice versa, where significant changes in speed and pitching angle occur.
Create a Win-Win Situation between the Knowledge Diffusion and the Benefits by Placing the Cost at the Threshold
Authors: Wang Ya Nan , Wang Jun
Published: March 2024

Collaboration on knowledge is an essential channel for fostering the production and integration of knowledge. Knowledge collaboration user interactions can evolve into a network for knowledge collaboration. The "resources" variable has a significant effect on knowledge diffusion in the actual world. This paper examines the impact of resource production and consumption processes on the knowledge diffusion. We construct the knowledge diffusion model and determine the threshold for knowledge diffusion's propagation. We analyze the existing collaboration network dataset, Erdos Collaboration Network (ERDOS), and demonstrate that it exhibits clustering and small-world behavior. Using ERDOS data, we investigate the effect of resource generation and consumption processes on knowledge diffusion, as well as the role of self-learning and review mechanisms in this process. In addition, we find that the steady-state density of informed users is insensitive to both the benchmark knowledge diffusion rate and the maximum resource-mediated knowledge diffusion rate. In the actual world, managers can set the cost at the threshold, creating a win-win situation between the degree of knowledge diffusion and the benefits.
Bending Ovalization of Thin-Walled Circular Tubes
Authors: Iandiorio Christian , Salvini Pietro
Published: March 2024

This paper presents a new analytical model to predict the mechanical behaviour of an elastic straight thin-walled circular tube (pipe) subjected to bending. A thin-walled pipe cannot be modelled as a simple beam, inasmuch it presents a shell-like behaviour due to the ovalization (in-plane warping) of the cross-section when loaded. The section modification implies a non-linear trend between the applied moment and the axial curvature, i.e. a non-invariance of the section moment of inertia. Two analytical ways are proposed in the reference literature: a rigorous one due to Reissner use a stress-function approach, and an approximated one, first due to Brazier, that follows Ritz approach. The Reissner model is analytically unsolvable and difficult to face numerically due to some integral conditions to fulfill. On the contrary, the Ritz approach is easy to implement, but being Heuristic is limited to circular sections. To overcome the previous mentioned difficulties a new geometrically exact Pipe model in terms of displacements is proposed, which turns out to be a mix between a shell and a beam model. The present approach leads to a system of ODEs accompanied by Boundary Value Problems (not requiring any integral conditions) that can be solved using a direct collocation method. After solving it, we build-up the dimensionless (non-linear) moment-curvature diagram, valid for any straight pipe, i.e. for every diameter, thickness, and whatever linear elastic material. The results are compared with other literature solutions performed using the Ritz’s approach and with Finite Element Analysis.
Assessment of Localization Strategies in a Radial Basis Function Meshless Method to Solve Two-Dimensional Convection-Diffusion Problems
Authors: Granados Julián Mauricio , Oquendo Gabriel Arturo , Bustamante Carlos Andres , Florez Whady Felipe
Published: March 2024

Two-dimensional Poisson and convection-diffusion problems are solved by using three localization schemes implemented in the context of a Radial Basis Function (RBFs) collocation method. The first scheme uses the traditional RBF superpositions to approximate the problem variable in a defined stencil. The second scheme is the Partition of Unity strategy and it is used to obtain a representation of governing equations as a linear combination of RBFs local superpositions evaluated at neighbouring stencils. Weight functions are designed to capture the convection term effect on the solution. In the third scheme, an upwind strategy is included in the Partition of Unity scheme for solving the convection-diffusion problem by moving and deforming stencils based on velocity. For all schemes, stencils in the form of crosses, circles, and squares are considered, and Root mean square (RMS) is obtained as a function of shape parameter, nodal distribution size and stencil size. In the case of Poisson problems, the use of Partition of unity in circular configuration with no more than 37 nodes per stencil is recommended as far as a $c$ suitable range is obtained for each nodal distribution employed to avoid ill-conditioning issues.
Titanium Nitriding: A Systematic Literature Review
Authors: Yuda Aria Wira , Arifin Amir , Yani Irsyadi , Oemar Barlin
Published: March 2024

In the last twenty years, the manufacturing of titanium and its alloys for commercial use continued to expand. As this material has several very advantageous properties, leading to increasing applications in various industries, it is seldom used in mechanical engineering applications due to its tribological properties, which are unfavourable. The nitriding process is one of the most frequently used thermochemical processes designed to enhance the surface characteristics of titanium alloys and improve tribological properties. Various types of nitriding for titanium are studied, such as ion nitriding, plasma nitriding, laser nitriding and gas nitriding. This article provides a comprehensive examination of research papers on different advancements through a systematic literature review conducted in the period 2017-2023 about titanium nitriding for its process parameters, characteristics and functionalities of the product, particularly emphasising their contributions in surface characteristics and mechanical properties. The review seeks to offer an understanding of how the predominant processing factors, specifically temperature and time, affect the microstructure and the creation of novel phases. This review suggests a challenge for future researchers to investigate mechanisms of microstructure evolution and its impact on mechanical properties in conditioned environments to microhardness and ability to withstand rusting of titanium and its alloys.

Introduction: The MBBS curriculum is one of the most strenuous graduation courses worldwide, leading to constant anxiety and stress regarding good performance in a MBBS students’ life. It requires regular, consistent hard-work and dedication to acquire medical knowledge and skills. In this highly competitive studious environment, some students are left behind, affecting their psychosocial wellbeing and growth. Few unsuccessful candidates become hopeless due to lack of guidance and multiple learning issues leading to repeated failures in professional examinations. We aimed to identify problems affecting both the personal and academic domain of these students leading to failure at the 1st MBBS Annual Examination and intervene with multimodal measures to improve their academic performance by teaching, guidance and counselling.Methodology: The study was conducted on 46 first year MBBS students including 18 multiple attempt students and 28 first attempt supplementary students. The cause of failure was assessed through a questionnaire. Multimodal interventions targeting specific problem areas in individual students were implemented for a period of 1 month after the annual result declaration.Results: Multiple academic and personal factors were observed among the failed students. The academic performance improved with passing percentage of 66.7 % in multiple attempt students and 92.9% in first attempt supplementary students.Conclusion: An active teaching-learning multi-modality intervention comprising academic and psychosocial components is essential for the success of failed students in addressing their personal and academic needs.

Introduction: Continuous Professional Development (CPD) is a system of practice that plays an integral part in honing the knowledge, skills, attitudes and mindsets of healthcare professionals leading to improved patient experiences and better health outcomes, the world over. CPD in the Sri Lankan context is at the cusp of a monumental achievement. Following many years of discussions and setbacks, the National Continuous Professional Development (NCPD) framework has finally reached operational status with pilot programs being planned in several districts.Methodology: we referred to local literature, official documents and various research studies centered around CPD in an effort to detail the history of CPD activities in Sri Lanka, the establishment of the NCPD framework, the obstacles encountered during previous attempts of implementation, the journey thus far and the way forward for a sustainable, long-lasting NCPD program that is beneficial for all Grade Medical Officers (GMOs) and health professionals later on.Results: Findings included uptake of a wide array of e-learning modalities following the COVID-19 pandemic. Multiple research studies showed that stakeholders were satisfied with the cost-effectiveness, heightened productivity, convenience, flexibility and information accessibility offered by web-based CPD initiatives. However, the underdeveloped digital infrastructure remained the main drawback of adopting e-learning strategies in our context.Conclusion: E-learning platforms that gained traction during the COVID-19 pandemic have become a boon to actualizing the NCPD program together with the steps taken to strengthen the local digital infrastructure. This promises to mark the next major era of Medical Education in the country.

In questo lavoro discuto la natura del delirio per prospettare un approccio terapeutico alla psicosi. Particolare attenzione è data alla natura e alla struttura dell'esperienza delirante e alla sua relazione con la parte sana della personalità. Se delirio rappresenta una costruzione psicopatologica che oblitera la capacità di comprendere l'esperienza emotiva, il lavoro terapeutico consiste nel ridurre il suo potere per recuperare il pensiero intuitivo e ristabilire il contatto con la realtà emotiva. Esiste un posto nella mente del paziente, virtualmente inaccessibile, in cui viene continuamente costruito lo stato psicotico. Di qui deriva l'importanza di orientare il lavoro analitico verso la presa di consapevolezza del significato dell'organizzazione psicotica, che tende ad inglobare il sè e a distruggere il senso di realtà. In questo senso, come ho cercato di mostrare nei frammenti clinici riportati nel lavoro, i sogni psicotici sono molto utili perchè costituiscono la vera comunicazione all'analista che non si realizza fino quando il paziente rimane complice e sottomesso all'organizzazione delirante. Da questo punto di vista mentre il delirio nasconde, il sogno comunica.
I paradossi della congiunzione crescente di W. Bion alla luce della teoria della complessità
Authors: Lenti Gabriele
Published: March 2024

Il presente lavoro tratta del rapporto tra la psicoanalisi e la teoria della complessità, un"impostazione epistemologica che si è andata sviluppando negli ultimi decenni. Si sostiene che il contributo teorico necessario sia da individuare nello studio della logica sottostante il campo di indagine della psicoanalisi, in questo modo si individuano i concetti di non-linearità, di autopoiesi e di ologramma del campo analitico che devono essere tenuti presenti per comprendere appieno la natura reale dei fenomeni studiati. La psicoanalisi potrà così dare il suo contributo alla teoria della complessità proponendo nuovi sviluppi di senso. Psicoanalisi e complessità potranno così entrare in un rapporto conviviale che feconderà entrambe le discipline.
Valutare la psicopatologia grave nell'adolescenza: alcune ipotesi sul trauma e la dissociazione per la comprensione dell'organizzazione borderline
Authors: Albasi Cesare
Published: March 2024

l'articolo riflette sulla salute e sulla psicopatologia nell'adolescenza in una prospettiva evolutiva che si nutre dell'orientamento relazionale in psicoanalisi, della teoria dell'attaccamento, dell'infant research. La salute è intesa con riferimento alla soggettività personale dell'adolescente e quindi come possibilità di fare esperienza della propria esistenza come occasione di realizzazione di potenzialità specifiche che lo contraddistinguono come individuo in crescita. Caratteristiche della salute sono la capacità di integrazione mentale, la flessibilità delle funzioni mentali e dell'organizzazione della personalità, la possibilità di elaborare i conflitti (intrapsichici ma intesi in senso relazionale e non pulsionale) con capacità che si vanno strutturando come sostegno allo sviluppo, la resilienza necessaria per fronteggiare le esperienze potenzialmente traumatiche, perchè disconoscenti le proprie necessità evolutive specifiche, senza strutturare processi dissociativi pervasivi. La psicopatologia è concepita in modo strettamente connesso alla diagnostica, con riferimento al PDM, e discussa con riferimento ai livelli di organizzazione: particolare attenzione è posta sul livello organizzazione borderline e sui processi dissociativi sul loro ruolo nell'organizzare i livelli borderline di organizzazione della personalità.
La consultazione psicologica in adolescenza
Authors: Vanni Fabio
Published: March 2024

Il testo traccia le linee generali di un modello di consultazione psicologica con l'adolescente che si rifà alla teoria del soggetto relazionale elaborata all'interno della Società Italiana di Psicoanalisi della Relazione. Una volta richiamati i punti principali del pensiero teorico sull'età adolescenziale che fa da retroterra alla clinica, viene declinata l'impostazione della consultazione a partire dalla concezione sistemica degli attori in campo, sia per la parte clinica che per quella dell'adolescente, il contesto, gli obiettivi. La consultazione viene assunta come momento centrale della clinica psicologica dell'età adolescenziale e descritta in tutta la sua complessità conoscitiva, decisionale, interattiva e dinamica. Viene proposta come un processo diagnostico e terapeutico che può concludersi in sè o fare da premessa a sviluppi terapeutici diversificati co-costruiti sulle esigenze specifiche di quel sistema che ha al centro l'adolescente. Numerose esemplificazioni cliniche aiutano a comprendere le proposte tecniche.
Dalla coppia alla famiglia
Authors: Milanesi Paolo
Published: March 2024

l'autore prende spunto dai lavori del Gruppo di Losanna per sostenere la tesi della polarità duale quale ambito specie-specifico del divenire dell'essere umano. Questa tesi viene esposta nella cornice epistemologica della complessità. Secondo l'autore la differenziazione tra duale, triadico o multi personale rappresenta un falso problema: l'ambiente è normalmente multiforme e variegato, ma il rapporto con l'Io-soggetto è sempre duale, nella misura in cui il contesto diventa unificato nella percezione gestaltica di un insieme di più individui quale altro polo dell'interazione. l'individuo può entrare in rapporto con il gruppale o il multiforme, ma sempre e soltanto attraverso una polarità che riduce gli elementi a due: io-altro/i. Viene poi approfondita la comprensione del divenire dell'uomo alla nascita di un figlio, sottolineando il delicato passaggio dalla coppia alla coppia genitoriale e poi alla famiglia. l'articolo si conclude con una breve elencazione di alcuni possibili significati dell'investimento che la coppia coniugale/genitoriale attua verso il proprio figlio.
La patologia borderline come livello di organizzazione di personalità
Authors: McWilliams Nancy
Published: March 2024

l'autrice passa in rassegna la storia del concetto di organizzazione borderline di personalità, come si è sviluppata attraverso varie esperienze cliniche con i pazienti e nella valutazione diagnostica della personalità. l'articolo mette bene in evidenza l'importanza di tenere a mente che i pazienti borderline lottano con interminabili problemi evolutivi. Critica la definizione ristretta di disturbo borderline di personalità secondo la descrizione del DSM e sostiene che, sebbene questa etichetta fondata su un criteri dicotomici sia stata utile per i ricercatori, un costrutto più dimensionale e meno categorico riveste un valore maggiore per chi pratica la psicoterapia. Inoltre, l'autrice delinea numerose funzioni mentali ed emotive mature che mancano o sono gravemente compromesse nelle personalità borderline. Sono citati parecchi approcci recenti e degni di apprezzamento al trattamento dei pazienti borderline e vengono anche messe in evidenza diverse implicazioni terapeutiche che tutti hanno in comune.
Occuparsi dell'altro: compito interrotto da perseguire?
Authors: Galardi Daniela
Published: March 2024

l'Autrice, psicanalista esperta di psicologia delle emergenze, vuole approfondire le motivazioni sottese al prendersi cura delle vittime in situazioni di eventi disastrosi. La coazione a ripetere che si evolve in "coazione alla cura" diventa la possibilità per il terapeuta di "occuparsi di sè" attraverso la relazione di aiuto. A partire da questa ipotesi, l'autrice si interroga sul rischio di instaurare una collusione che potrebbe ri-traumatizzare il paziente e bloccarne lo sviluppo. La maggior consapevolezza dell'analista delle proprie funzionalità inconsce può permettergli di costruire con la vittima/paziente un processo interpersonale, caratterizzato dalla condivisione, ma anche dalla distanza necessaria per riflettere su quanto sta accadendo. Diventa così possibile "dare parola": nuova narrazione che nel suo essere condivisa diventa esplicita e riconoscibile. Tale opportunità è un"alternativa alla ripetizione dei conflitti intrapsichici del passato, che riapre la processualità del divenire evolutivo e il perseguimento del desiderio nella sua dimensione reale-progettuale.
