Community Detection in Modular Complex Networks Using an Improved Particle Swarm Optimization Algorithm
Authors: Abduljabbar Dhuha Abdulhadi
Published: August 2023

Community detection is an important and interesting topic for better understanding and analyzing complex network structures. Detecting hidden partitions in complex networks is proven to be an NP-hard problem that may not be accurately resolved using traditional methods. So it is solved using evolutionary computation methods and modeled in the literature as an optimization problem.  In recent years, many researchers have directed their research efforts toward addressing the problem of community structure detection by developing different algorithms and making use of single-objective optimization methods. In this study, we have continued that research line by improving the Particle Swarm Optimization (PSO) algorithm using a local improvement operator to effectively discover community structure in the modular complex networks when employing the modularity density metric as a single-objective function. The framework of the proposed algorithm consists of three main steps: an initialization strategy, a movement strategy based on perturbation genetic operators, and an improvement operator. The key idea behind the improvement operator is to determine and reassign the complex network nodes that are located in the wrong communities if the majority of their topological links do not belong to their current communities, making it appear that these nodes belong to another community. The performance of the proposed algorithm has been tested and evaluated when applied to publicly-available modular complex networks generated using a flexible and simple benchmark generator. The experimental results showed the effectiveness of the suggested method in discovering community structure over modular networks of different complexities and sizes.

Authors: Eaton Maxwell , Zhang Yuanzhe , Liu Shih-Yuan
Published: August 2023

Borataalkenes are the boron-containing isoelectronic analogues of alkenes. Compared with alkenes, the borataalkene ligand motif in transition metal coordination chemistry is relatively underexplored. In this tutorial review, the synthesis of borataalkene complexes and other transition metal complexes featuring the η2-B,C coordination mode are described. The diversity of coordination modes and geometry in boraatalkene complexes, and the spectroscopic and structural evidence supporting their assignents are highlighted. The applications of the borataalkene ligand motif in homogeneous catalysis, especially those involving 1,4-azaborines, is discussed. Finally, the use of borataalkene complexes as reactive intermediates in catalysis, usually derived from geminal diboron compounds is summarized.

The Effects of Rhythm on Building Openings and Fenestrations on Airflow Pattern in Tropical Low-Rise Residential Buildings
Authors: Oforji Peter I. , Mba Emeka J. , Okeke Francis O.
Published: August 2023

Effective passive airflow in low-rise residential buildings in hot-humid environment is crucial to maintaining good indoor thermal comfort for occupants. However, investigation of effects of the rhythm of window openings on achieving a passive airflow pattern in such buildings in the tropical climate of sub-Saharan Nigeria have been rarely studied. Therefore, this research aimed to evaluate the effects of the rhythm of window openings on passive airflow patterns for indoor thermal comfort in low-rise residential buildings in the hot-humid environment of Obosi, Nigeria. It involved experimental research using the Anemometer TA465 instrument for measuring wind velocity, relative humidity, and temperature of the purposively designated buildings in the three layouts of the study area for both wet and dry seasons. Employing the Yamane statistical formula, a sample size of 433 was obtained, and questionnaires were administered to occupants of the studied buildings and analyzed using categorical Regression Analysis (CATREG). The regression analysis showed that p=0.000, i.e. p<0.05 indicating that there was a significant relationship between the type and sizes of windows (elements used in measuring rhythm) and the intensity or force of breeze (a measure of passive airflow pattern). Further analysis of the data involved the use of Autodesk CFD 2018 (Computational Fluid Dynamics) for building wind flow simulations. The result showed variations in temperature levels (indications of differences in indoor thermal comfort) of various indoor spaces of the investigated designated floors and buildings, especially ground floors and the top-most floors of the buildings. The study underscored the need to use architectural rhythm design strategies to create a positive impact on airflow patterns in low-rise buildings, especially in densely built-up urban areas. The results of this study are instructive in noting that in order to attain passive airflow in buildings in the face of challenge of land restrictions, vertical stacking of building floors could be used once an adequate rhythm of window openings is adopted. Doi: 10.28991/CEJ-2023-09-08-016 Full Text: PDF
A Review of Advances in Peat Soil Stabilisation Technology: Exploring the Potential of Palm Oil Fuel Ash Geopolymer as a Soil Stabiliser Material
Authors: Amaludin Adriana Erica , Asrah Hidayati , Mohamad Habib M.
Published: August 2023

This study aims to highlight the latest developments in the field of peat soil stabilisation technology via chemical stabilisation. The review examines the use of traditional stabilisers such as OPC and various non-traditional stabiliser materials, i.e., Palm Oil Fuel Ash (POFA)-OPC blends, chemical solutions, and geopolymer materials, to enhance the Unconfined Compressive Strength (UCS) characteristics of peat soils based on the ASTM D 4609 requirements. OPC, POFA-OPC blends, and alkaline solutions mostly produced stabilised soil samples that fell short of the ASTM requirements. Existing studies on the use of waste-derived geopolymers to treat peat soils are limited, while the use of POFA geopolymer materials has mostly focused on the improvement of clayey and silty soils. The results of soil stabilisation with geopolymer were very encouraging, as the strength gains were in line with the ASTM soil strength requirements. As a result of this review, it can be concluded that POFA geopolymer is a viable soil stabiliser material with the addition of Ground Granulated Blast Furnace Slag, and that the use of POFA-GGBFS geopolymer to enhance the strength properties of peat soils should be investigated. Doi: 10.28991/CEJ-2023-09-08-017 Full Text: PDF

Ethics in Terminal Palliative Care: A Nursing Perspective
Authors: Elyeli Kemal , Esmaeilzadeh Samineh
Published: August 2023

Background/Objective: The World Health Organization defined palliative care as follows: “Palliative care is an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening
illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psycho social and spiritual.” Palliative care can be defined
as a multidisciplinary approach to control the symptoms of terminal illness, increase the quality of life, and provide psychosocial support to patients and their families. Terminal diseases are incurable, progressive and life-threatening
diseases. The goals of palliative care are to increase the quality of life of patients, to control symptoms, to provide psychosocial support and to support families. Palliative care services can provided to children, adults and
elderlies and who patients with terminal diseases such as cancer patients, advanced heart, lung and kidney diseases. These services are provided in accordance with the needs of patients and their families and are carried out with
a multidisciplinary approach. An important part of this approach is the participation of nurses. In this process, the ethical responsibilities of nurses are very important. Nurses should provide the medical and psychological care
needed to ensure the best possible quality of life in the patient's last days according to ethic codes. The aim of this review is to examine the issue of palliative care in terminal patients and ethical approaches in this regard
from a nursing perspective in the light of current literature. Conclusions: It is important that nurses, who spend the most time with patients and represent the most focused group of professionals in the health care team, are an
integral part of palliative care. Therefore, it is important to provide care especially considering the ethical principles of the care receiver. Also for nurses to approach ethical and palliative care principles in order to increase
the quality of life of the patient, to approach the patient's pain in a sensitive way, to respect the patient's autonomy and to provide psychological support in the last period of the patient.

The aim of this study was to determine the effect of the intensity of the yellow LED light and the sound intensity of religious music (Asmaul Husna) on the growth of various types of chili plants in indoor system. The research method uses experimental research. This research was conducted in Baitussalam District, Aceh Province. This research was conducted for a month. Based on the results and discussion, it can be concluded that exposure to LED lights and religious music (Asmaul Husna) has a fairly good effect on the growth of stem height, number of leaves and leaf width of the three types of chili plants tested. This is because the addition of light in the form of LEDs and sound can help the plant photosynthesis process to be more productive and accelerate the growth of the third type of chili. From the three types of chili, the most significant effect is in terms of plant height, leaf width and number of leaves found in chili peppers compared to the results obtained on cayenne pepper and green chili.

Unsteady and Incompressible Magneto-Hydrodynamics Blood Flow in an Inclined Cylindrical Channel
Authors: Liaqat Hussain , Salah Uddin , Asif Shahzad
Published: August 2023

In the current study, the blood flow through an inclined cylindrical tube subjected to an external magnetic field is evaluated. The blood flow has been considered under the consequence of a transverse magnetic field. Previously the mathematical model was solved by using Caputo-Fabrizio (CF) fractional order derivative with a non-singular kernel which has the limitations like it fails to satisfy the fundamental theorem of fractional calculus. Whereas, in the present study Adomian Decomposition Method (ADM) which is suitable for all types of linear and non-linear differential equations is used. The flow of magnetized blood in an inclined cylindrical tube has been studied by using the ADM. An external magnetic field and an oscillating pressure gradient drove the blood flow. ADM algorithm has been developed and used to find the Adomian solution. Computer software MATHEMATICA has been used to visualize the influence of various flow characteristics such as Hartmann number (Ha), different radial locations and angle of inclination on the Adomian velocity. Due to the Lorentz effect and central radial location, the results show that the magnetic field diminishes the velocities of blood. Meanwhile, progressive inclination angle enhanced the blood flow.

How anticipatory remapping along the saccade direction predicts peri-saccadic biphasic mislocalization
Authors: Berreby Yohaï-Eliel , Krishna B S
Published: August 2023

When we view the world, we move our gaze to bring light from different parts of the scene to the fovea. A given static stimulus in the visual scene therefore falls on different parts of the retina before and after a saccade. It has been shown that neurons in many visual and oculomotor “priority-map” brain areas respond to stimuli appearing before the saccade at the spatial location that their receptive field will occupy after the saccade, as if they are anticipating the consequences of the saccade. In a separate line of work, psychophysical studies have shown that stimuli flashed around the time of a saccade are systematically mislocalized in various characteristic patterns --- one of these is a biphasic pattern where flashes right before a saccade are mislocalized in the saccade direction and flashes right after a saccade are mislocalized opposite to the saccade direction. The anticipatory remapping along the saccade direction and the mislocalization along the saccade direction have been suspected to be linked, but there has been no explicit model of how they might be linked and some studies have called this connection into question. Here, we present a circuit model that shows how anticipatory remapping along the saccade direction predicts biphasic mislocalization of brief peri-saccadic flashes similar to that seen in empirical data. The mislocalization, rather than being an artifact of the remapping, is a result of incomplete remapping right before the saccade and residual remapping after the saccade. Smaller magnitudes of remapping before the saccade lead to larger forward mislocalization of pre-saccadic flashes, and smaller magnitudes of remapping after the saccade lead to smaller backward mislocalization of post-saccadic flashes. The model is consistent with the known physiology of RF remapping and trans-saccadic information transfer and makes clear predictions regarding the dynamics of RF remapping and trans-saccadic response updating for task-relevant stimuli that can be tested in future experiments. To the extent that RF remapping mechanisms along the saccade direction impact the same representations that may be used for the spatial localization of peri-saccadic flashes, they predict a biphasic mislocalization pattern for peri-saccadic flashes that is similar to what has been shown empirically.

The functioning and structure of most European forests are actively shaped by intensive human use. Harvesting of wood is one of the key processes of forest management, making it a crucial element to include in any large-scale analysis of forest ecosystems. Yet, our understanding of how forests are harvested across Europe is limited, as the true harvest regimes – a realisation of decisions made by individual forest owners – are not well described by aggregated wood harvest statistics or formal management guidelines. To fill this gap, we analysed recent forest harvest activity, as observed in permanent plots of forest inventories in eleven European countries, totalling to 182,649 plots and covering all major forest types from boreal to Mediterranean forests. We aimed to (1) characterise harvest regimes through the frequency and intensity of harvest events spatially across Europe, and (2) build predictive models for the probability and intensity of harvest events at the plot-level, by linking individual harvests to the pre-harvest forest structure and composition, but also to climatic, topographic and socio-economic factors, as well as past natural disturbances. The results reveal notable variation in harvest regimes across Europe, with different harvest strategies emerging in regions with similar total harvest rates. These include, for example, low-frequency but high-intensity harvest regimes in northern Europe and high-frequency but low-intensity harvest regimes in eastern Central Europe. The harvest regimes were strongly driven by country-level variation, emphasising the role of national level factors in driving harvest patterns. Pre-harvest forest structure and composition was an important driver for the intensity of harvest events, whereas probability of harvest was more related to socio-economic factors and the occurrence of natural disturbances. The empirical quantification of the current forest harvesting regimes across Europe presented in our study provides much needed detail in our understanding of the contemporary forest management practices in Europe, crucial for understanding how human activities shape forests and providing a baseline against which to assess future changes in management.
A Qualitative Study of Why Students Choose to Study Veterinary Nursing
Authors: Harniman Suzannah
Published: August 2023

Veterinary nursing (VN) is a popular subject amongst undergraduate students, but due to the high attrition rates from the profession there is a shortage of registered VNs. By identifying the factors that motivated student VNs to enroll on their degree and persist to the final, it may be possible to enhance the support available for students when they are deciding whether to study VN.

Online semi-structured interviews were used with 10 student participants from the final year of a BSc (hons) VN program. The data were analyzed using a six-step method of thematic analysis. The Situated Expectancy-Value Theory was used as a framework to interpret the results and allowed for an in-depth understanding of the participant's values and beliefs to be obtained.

The results highlighted that a high intrinsic value for animals is a common reason for enrolling on the program, but that, partly due to the representation of the VN profession in marketing materials, at enrollment students do not seem to have a thorough understanding of the VN job role. As students’ progress through their training journeys, they develop a sense of professional identity that motivates them to continue, but they also gain an insight into the challenging reality of the VN role.

VN marketing materials need to be improved to ensure they provide prospective student VNs with an accurate insight into the realities of the VN job role. They will then be in a position to make an informed choice to join the VN profession.

Goniometry is an essential skill used in veterinary rehabilitation settings to monitor orthopedic conditions. Our objectives were to create a normal canine stifle goniometry model and to compare students’ confidence and accuracy in performing goniometry with exposure to either the model or traditional teaching methods. We hypothesized that students would demonstrate goniometry skills more confidently and accurately after using a simulation model than those given traditional materials. A flexible model of a canine stifle was made. Twenty-eight veterinary students (8 clinical, 20 pre-clinical) prepared with either instructional material from a textbook ( n = 15) or access to the stifle model ( n = 13), and then assessed when performing goniometry (live dog). Students completed pre- and post-surveys where they indicated their confidence and anxieties. Statistical analyses included thematic analysis, descriptive statistics, and Chi-square analyses (significant at p ≤ .05). There was no difference in goniometry assessment or anatomy palpation scores between the model and reading groups. Clinical students ( n = 8) achieved higher scores in goniometry assessment ( p = .01) and anatomy palpation ( p = .04). Students were more confident when identifying their anatomical landmarks after using prep materials as compared to before using the prep materials ( p = .03), but only averaged identification of 3/5 landmarks. Half could not correctly read the goniometer. In general learning with models was preferred by all. There was no difference in learning between the model and textbook, so either can be used based on student preference. Further goniometer instructions should be provided. Anatomy of live dogs should be assessed more frequently pre-clinically.
Introduction

Since early 2020, the covid-19 pandemic has unfolded as a global crisis that poses significant challenges to governments and societies.1 Governments have reacted quite variably, with policies ranging from strict lockdowns over a longer period of time to flexible approaches with restriction of freedoms at very low thresholds of intrusion into citizens’ rights.2 While the pandemic does not affect everyone equally, and some countries are more advanced in containing the virus than others, the sense of vulnerability and insecurity is widespread. In addition to the 6.5 million people who have died from covid-19 as of late August 2022, many more are affected by ongoing symptoms of long covid-19. Increased economic disparities and new forms of inequality only exacerbate the degree of uncertainty and the feeling that life is out of control.3 However, the popular yearning to regain control has not led to an unambiguous “desire for the state.”4 Rather, trust in governments has fluctuated in the wake of the pandemic. If there was a “rally around the flag” effect, it was certainly not found in every country.5 Even if support for government regulations and restrictions were prevalent within a state, it was not shared equally by different parts of the population. In several countries, the pandemic has also given rise to substantial protests against the restriction of civic, economic, and social liberties, often driven by fears of state surveillance, libertarian rebellion against state paternalism, and conspiratorial beliefs.6

Published: August 2023

The infrastructure of smart cities is intended to save citizens’ time and effort. After COVID-19, one of such available infrastructure is electronic shopping. Online consumer reviews have a big influence on the electronic retail market. A lot of customers save time by deciding which products to buy online by evaluating the products’ quality based on user reviews. The goal of this study is to forecast if reviews based on reviews representation mining will be helpful while making online purchases. Predicting helpfulness is used in this suggested study to determine the usefulness of a review in relation to glove vector encoding of reviews text. Using an encoding-based convolution neural network and a bidirectional gated recurrent unit, the authors of this study constructed a classification model. The suggested model outperformed these baseline models and other state-of-the-art techniques in terms of classification outcomes, reaching the greatest accuracy of 95.81%. We also assessed the effectiveness of our models using the criteria of accuracy, precision, and recall. The outcomes presented in this study indicate how the proposed model has a significant influence on enhancing the producers’ or service providers’ businesses.
L'azione dei comuni italiani per la pace e la costruzione dell'Europa dopo la Seconda guerra mondiale
Authors: Zucca Fabio
Published: August 2023

Il contributo, dopo una breve premessa iniziale, ripercorre la vicenda storica, precedente e successiva alle guerre del secolo scorso, che ha portato alla costituzione del Consiglio dei Comuni d'Europa (CCE), ponendo in rilievo il contributo italiano nel periodo del secondo dopoguerra allo sviluppo del ruolo delle autonomie locali nel processo di integrazione europea come base politico-ideale e socio-territoriale di formazione di una Europa dei cittadini
Simboli religiosi e multiculturalismo. Il caso del Crocifisso
Authors: Negri Carla
Published: August 2023

Il contributo affronta la questione dell'esposizione dei simboli religiosi nella scuola pubblica, in cui si trovano a convivere diverse tradizioni religiose e culturali, ripercorrendo le principali tappe del cammino giurisprudenziale sul tema dell'esposizione del Crocifisso nella scuola, sia a livello nazionale che internazionale, con particolare riguardo alla sentenza della Corte di cassazione, Sezioni Unite, del 2021, che sembra sciogliere alcuni nodi problematici rimasti irrisolti nella precedente giurisprudenza, evidenziando come l'‘attività di ‘supplenza' dei giudici è insufficiente, perché lascia aperti alcuni spazi vuoti che richiederebbero l'intervento del legislatore e della classe politica da esso rappresentata.
Lavoro e solidarietà nel diritto dell'Unione europea, a partire dal principio fondamentale della libera circolazione
Authors: Comazzetto Giovanni
Published: August 2023

Il saggio offre un'analisi critica del concetto di "solidarietà transnazionale", connettendolo in particolare al tema dei diritti del cittadino migrante alla luce della giurisprudenza della Corte di giustizia dell'Unione europea sul concetto di lavoratore e sull'esercizio delle libertà di circolazione. Le difficoltà di concettualizzazione del principio di solidarietà nel diritto dell'Unione europea sono prima indagate nel quadro della perdurante incertezza sulla natura dell'ordinamento giuridico complessivo, e poi lette nella magmatica evoluzione della giurisprudenza che ha lentamente "costruito" i diritti connessi alla cittadinanza europea.
Il danno da vacanza rovinata e il ruolo nomofilattico della Cassazione tra inadempimenti contrattuali e autoregolamentazione del viaggiatore
Authors: Miletti Antonella
Published: August 2023

Il danno non patrimoniale da vacanza rovinata è una ingiusta lesione della persona (ex art. 2 Cost.), garantita – prima – dalla interpretazione costituzio-nalmente orientata dell'art. 2059 c.c. – successivamente – dal codice del turi-smo. La Corte di Cassazione è tornata sul tema della risarcibilità del danno da vacanza rovinata a seguito del mancato accoglimento da parte del giudice dell'appello della domanda di risarcimento per inadempimento contrattuale, per i disagi psicofisici generati alla mancata realizzazione della vacanza attesa.
Esiste la mente inconscia? La (ri)scoperta dell'inconscio alla luce delle neuroscienze
Authors: De Benedittis Giuseppe
Published: August 2023

La scoperta che una parte straordinaria della nostra vita mentale avviene al di fuori della nostra consapevolezza viene generalmente accreditata a Sigmund Freud, anche se storicamente è di molto antecedente. La mente inconscia è gene-ralmente considerata in psicologia generale come l'ombra della "reale" mente con-scia, ma vi è una significativa evidenza che l'inconscio non sia meno flessibile, complesso, intenzionale della sua controparte conscia. Numerosi sistemi inconsci regolano processi attentivi, percettivi, emozionali, mnestici, valutativi e motivazio-nali. Tali processi cognitivi si manifestano a livello inconscio e influenzano com-portamento ed emozioni (affetti). Le neuroscienze soltanto di recente hanno co-minciato a comprendere i correlati neurali di tali processi e le loro interazioni di-namiche con i processi consci. Ad esempio, come impulsi, pensieri e desideri consci diventino inconsci (e.g., repressione, dissociazione) e, d'altra parte, come impulsi, motivazioni e desideri inconsci diventino consci (e.g., lapsus e/o atti mancati freu-diani). Sulla base dell'evidenza disponibile, non esistono strutture e circuiti cerebra-li specificamente deputati all'elaborazione del pensiero inconscio, ma tutte le re-gioni del cervello partecipano al pensiero cosciente e non cosciente. Qual è il rap-porto tra inconscio e coscienza? Si tende a ritenere che le radici profonde della co-scienza e del senso di sé risiedano in un grande insieme di strutture cerebrali fina-lizzate alla mappatura neurale del corpo e all'omeostasi in modo non consapevo-le. Sarebbe questo il "Proto-Sé" Inconscio (Damasio, 2003), dal quale emergerebbe l'espe¬rienza cosciente. In questa prospettiva, si può arguire che le azioni della men-te inconscia precedono e influenzano l'emergenza della mente conscia. Non sap-piamo se queste attività implicite e automatiche possano essere concettualizzate e organizzate in una mente auto-inconscia che assomigli alla mente auto-cosciente. Anche se percezioni, sentimenti, motivazioni e alcuni processi decisionali possono verificarsi al di fuori della consapevolezza, ciò che sembra mancare è la capacità e l'intensità di queste attività implicite di auto-organizzarsi, possibilmente attraverso un meccanismo bottom-up di coalizioni neurali, in una rappresentazione coerente, significativa e mirata della realtà.
Metafore in 4D: quando l'ipnosi incontra il costruttivismo
Authors: Di Giusto Carlotta , Favaro Alessandra
Published: August 2023

In questo lavoro le autrici propongono una nuova tecnica esplorativa ed elabo-rativa del mondo interno del paziente, chiamata "metafore in 4d". Dopo una pre-sentazione dei principi della teoria costruttivista, si illustra, in dettaglio, la procedu-ra utilizzata, che combina la capacità esplorativa e di aumento di consapevolezza della tecnica costruttivista del laddering (strutturazione gerarchica del sistema di costrutti individuali), con la forza creatrice e promotrice di cambiamento delle me-tafore prodotte in ipnosi. La tecnica viene, infine, esemplificata nei suoi vari pas-saggi attraverso il report di un caso clinico.
Valorizzare il capitale umano per la gestione della diversità culturale
Authors: Pinna Pintor Stella , Ricucci Roberta
Published: August 2023

Il riconoscimento dei benefici dei processi migratori comporta necessariamente una adeguata valorizzazione del capitale umano tramite pratiche e politiche di gestione della diversità culturale, in primo luogo a livello locale. Le pratiche di diversity management, sviluppate principalmente nei contesti imprenditoriali, si pongono questo obiettivo. Tuttavia in Italia ci sono alcuni ostacoli al loro sviluppo, legati in particolare alle piccole dimensioni delle imprese e alle resistenze culturali diffuse. Risulta quindi necessario sviluppare delle pratiche che tengano conto della specificità del contesto italiano e del quadro culturale, insieme ad un aggiornamento delle normative per rimuovere gli impedimenti ad una buona integrazione della popolazione immigrata. Questi interventi non vanno declinati solamente nelle imprese in riferimento alla presenza straniera, si tratta piuttosto di tenere in considerazione l'intersezione delle diverse dimensioni dell'identità e, allo stesso tempo, dei diversi luoghi in cui queste si incontrano (oltre che nelle imprese, nelle scuole, nelle strutture sanitarie, nelle realtà associative, nelle università, nei contesti sportivi etc.). Infine, il presente contributo assume una funzione introduttiva dei diversi articoli che presentano, tramite lenti differenti, l'intreccio delle pratiche di gestione della diversità culturale e la valorizzazione del capitale umano.
Valorizzazione del capitale umano nei sistemi organizzativi complessi: il Diversity Management culturale nella prospettiva dell'Age Management
Authors: Falci Laura
Published: August 2023

La proposta si inserisce nell'interesse della ricerca sociologica ai molteplici processi che descrivono la complessità sociale della contemporaneità, attraversata da mutamenti demografici e investita dalle conseguenti trasformazioni in ambito socio-culturale nei sistemi organizzativi complessi, che vedono esponenzialmente accresciuto il grado di diversità al loro interno. Nasce così – come esigenza organizzativa quanto democratica in senso più ampio – la necessità di gestire tali mutamenti, comprendendo dal profondo gli elementi d'ostacolo alla promozione delle diversità nelle culture organizzative, attraverso lo strumento del Diversity Management (DM), che si prefigge di riconoscere e valorizzare il capitale umano di cui ogni singola persona che abita l'organizzazione è depositaria. L'articolo fornisce, infine, riflessioni teoriche applicate all'age diversity management, come esempio di incontro intergenerazionale e proficuo scambio di conoscenza al di là degli stereotipi e dei pregiudizi.
Il primo Servizio di psicologia di base in Italia
Authors: Cozzuto Armando
Published: August 2023

La Legge Regionale del 3 agosto 2020, n. 35, redatta e presentata dall'Ordine degli Psicologi della Regione Campania, ha istituito il "Servizio di psicologia di base", volto a sostenere e integrare l'azione dei medici nell'inter- cettare e rispondere ai bisogni assistenziali di base dei cittadini. Attualmente, tutte le ASL del territorio hanno deliberato e pubblicato un primo elenco degli psicologi idonei. Inoltre, l'osservatorio regionale sta lavorando alla formazione interna e sta predisponendo il programma formativo. Tali aspetti rappresentano un primo passo per il futuro della professione di psicologo, e fanno da apripista per quella che può definirsi una svolta storica per la professione psicologica nel nostro paese.
