Grounding is one of the most important parts of an electrical system. Earthing systems are done to protect the power system and the personnel from the danger of electrical shocks. Ceylon Electricity Board (CEB) uses a special structure for transformer earthing arrangement. The used structure is copper bonded earth rod with a concrete filled steel cage. Due to the complexity of the structure and the nonlinear variations in soil parameters, it is challenging to determine resistance before implementing the structure. We can use an analytical formula for structures to find the resistance. [4] But for complex structure, as we use here, it is challenging to produce an analytical formula. The other solution is to use a Finite Element Method(FEM) to solve the problem.[2] But is also a time-consuming task.[1] So, we propose a combination of FEM and a neural network-based solution for this task.[1]. We propose to generate a data set using FEM and implement it in a neural network.

Energy consumption modelling of electrical loads plays a crucial role in modern-day energy management systems for green commercial buildings. This project focuses on the development of power baseline modelling using deep learning techniques for a diverse range of electrical loads. The baseline model, an estimation of power or energy consumption before implementing energy management, is widely used to identify savings by comparing with the measured data after implementing energy management. Energy efficiency is crucial for both commercial and non-commercial applications. Power baseline models give reference to identify energy saving or loss. We can assess energy saving after implementing energy conservation strategies and identify energy wastage of the system when actual power consumption is higher than the power baseline model prediction. In this study specifically, a comparison is made between Karl's Pearson's and Random Forest-based deep learning approaches and Recurrent Neural Network (RNN) models. This project incorporates both simulations and real-world data to conduct the study.

Municipal solid waste management is a major issue for many nations striving for a sustainable future. According to the United Nations Environmental Programme report [1], Municipal solid waste management is both a resource and a burden as it contains valuables and leftover waste that need to be managed carefully to keep the public healthy. Biodegradable and non-biodegradable components make up the majority of this waste; the latter includes things like plastics, tires, e-waste, glassware, building debris, metals, ceramics, some textiles, and batteries. Notably, there is significant worry about non-biodegradable waste, especially plastics. Sri Lanka is currently experiencing an economic crisis, import restrictions, shortages of goods, and hike in foreign exchange rate, all of which highlight the need to adopt a circular economy. Natural ecosystems are seriously threatened by Sri Lanka's rapidly increasing plastic usage, which is increasing at a pace of 16% per year [2]. Every year, over 265,000 megagrams (Mg) of plastic are consumed [2], most of which wind up in landfills. Sri Lanka has not yet adopted practices akin to those of other nations that recycle plastic waste into the circular economy. Failure to convert plastic waste could lead to adverse impacts such as reliance on imports, financial losses, unstable foreign exchange rates, shortages of necessities, rising demand for plastics, problems with the carbon cycle and environmental equilibrium, resource depletion, and failure to meet the Sustainable Development Goals.

In the current world, the escalating waste problem has reached an alarming level. With the rapid growth of the population, the amount of waste generated has also increased, leading to significant challenges in its organic decomposition. Like many other regions, Sri Lanka is also facing many challenges due to inadequate waste management practices. One of the areas that help to solve this problem effectively is the development of waste recycling technology. Municipal solid waste takes a long time to decompose naturally and often produces unpleasant odors. Therefore, it is essential to develop an appropriate technology to accelerate their decomposition to manage the problem at the grassroots level. This research aims to provide a technical solution to these pressing issues in waste management and recycling. The scope of this research is to improve an ordinary kitchen garbage composting machine by introducing controlling variables such as temperature and humidity, heating capacity, aeration, and optimization of the local climate within the composting chamber to develop a conducive environment for microbial activities. This would enhance the microbial growth rate and increase the quality of compost while reducing the residence time of garbage. Other than this the research aims to reduce the odor during the recyclin.

Sri Lanka is aiming to make its electricity sector more environmentally friendly by 2050 by achieving carbon neutrality in the electricity industry. As a result, electricity generation is being planned to reach 70% of it by Renewable Energy (RE) sources [1]. According to the latest Long Term Generation Expansion Plan 2023-2042, our country will have 31% of its energy share from solar power [2]. However, the low efficiency and high cost of solar panels are currently a barrier to achieving this goal. The purpose of this study is to propose a method to increase the efficiency of the glass/FTO/CdS/CdTe/Cu/Au solar cell which was developed under laboratory conditions. CdTe solar cells are second-generation thin film solar cells that are more economical and can increase efficiency subsequently than the first-generation Si solar cells [3]. Solar Cell Capacitance Simulator (SCAPS 1D) software is used for the simulations and the software is validated using practically measured cell output parameters and simulation results to ensure its suitability for the study.

Published: July 2024

Bio-based adhesives are derived from renewable resources such as plant-based materials, animal by-products, and microbial sources. Latex-based bio adhesives, specifically those made from natural latex derived from plant sources, have garnered significant research interest. While natural rubber remains the most commonly used bio source for latex adhesives, this study explores the potential of Pterocarpus indicus wild (PIW) latex as an alternative and discusses modifications that can be made to enhance its adhesive properties. Additionally, this research examines the effect of additives such as Polyvinyl Alcohol (PVA) on the adhesive properties of natural latex while evaluating their capacity for adhesive performance. The major challenges faced by existing bio-based adhesives, including low bonding strength and water resistance are acknowledged. Consequently, this study offers guidance on advancing new plant sources for bio-based adhesives, addressing the limitations of current adhesive products. Adhesives are social substances and can be defined as a mixture in a liquid or semi-liquid state, capable of joining permanently to surfaces, by an adhesive process [1]. Bio- based adhesives are a type of adhesive that is made from natural and renewable resources, such as plant-based materials [2]. These adhesives are becoming increasingly popular due to their sustainability and environmentally friendly nature, as they have a reduced carbon footprint and are biodegradable. The disadvantages of the current bio sealants can restrict their use in some circumstances. Their lower strength and longevity compared to conventional adhesives are significant drawbacks. Some bio-based adhesives are also moisture-sensitive and may lose their adhesion when exposed to moisture or high humidity [3]. Due to the higher expense of obtaining and processing natural materials, bio- based adhesive production has another disadvantage. Additionally, bio-based adhesives' scalability and broad use may be constrained by the lack of readily available natural materials. Additionally restricting their use in some applications, some bio-based adhesives have a lower shelf life than conventional adhesives.

Robot controllers are crucial when executing high-level algorithms. Sometimes designing these controllers from scratch will be the best solution for building robots. However, the process will consume much time to build all the electronics and other mechanical hardware from scratch. Therefore, for rapid prototyping continuing from the available hardware will help a lot to save time. Additionally, low-level controllers are crucial when it comes to autonomous robot manipulations [1]. The outcomes produced via these embedded systems [2] will directly pass to the actuators to operate robots. Therefore, the accuracy of these controllers will also cost the overall accuracy of the entire system [3]. There are many types of controlling mechanisms to control wheelchairs. The pieces of evidence from the literature give many examples[4-7]. Out of these controlling techniques, controlling via a joystick [8] is the default controlling mechanism for almost all wheelchairs. When designing novel controlling mechanisms, the way of perceiving environmental details and delivering control signals that are produced with the algorithms is very important and crucial. When exploring the literature, it shows that layered architecture is preferred for implementing controller mechanisms[9,10]. However, the possibility of integrating hardware systems on top of available designs are challenging task to achieve. Even though the literature shows many developments for controlling mechanisms, scaling these hardware units to align with the present knowledge expansions on the algorithms is far below the expected level. Therefore, this work proposed a novel layered hardware unit to replace existing joystick-based controllers and integrated software modules with the help of the proposed layered architecture. Moreover, the work suggests injecting the data by replacing the already available joystick controller of the wheelchairs. In the rest of the article, section II will introduce proposed architectures, and section III will showcase the results based on the observations and follow up with the discussion. Section IV will conclude the paper with future directions.

Coconut is the third largest cash crop grown in Sri Lanka. There are a variety of coconut-based products available, and deshelling is an essential step in the manufacturing processes of all those products. However, the deshelling process faces several safety concerns which are yet to be addressed. It was found through field visits that on average, 4 accidents per month are reported by the laborers who work in deshelling machines. These injuries are caused by slippage of coconut when it is held onto the cross cutter of the deshelling machine. Another concern was that the coconut kernel was damaged slightly by the cross-cutter, the cutting wheel of the current machine. This damage is significant when a large-scale coconut processing plant with over 200,000 nuts daily capacity is considered. The scarcity of skilled laborers to operate the deshelling machines is another challenge. Training new laborers is both a time-consuming and costly process. Therefore, this research aims to develop a new mechanism for coconut deshelling to be used in an industrial setup. The mechanism intends to enhance the safety of the operation while reducing the damage to the kernel and to reduce human intervention in the process. The scope of this project is limited to deshelling a coconut starting from dehusked coconut and the intended output is kernel with brown skin while dehusking and paring will be out of the scope
On the stability of linear systems with a quadratic integral
Authors: Kozlov V. V.
Published: July 2024

The problem of stability of non-degenerate linear systems admitting a first integral in the form of a non-degenerate quadratic form is considered. New algebraic criteria for stability, as well as complete instability of such systems, have been established in the form of equality to zero of traces of products of matrices, which include an additional symmetric matrix. These conditions are closely related to the symplectic geometry of the phase space, which is determined by the matrix of the original linear system and the symmetric matrix defining the first integral. General results are applied to finding conditions for complete instability of linear gyroscopic systems.

Authors: Malai N. V. , Sohan P. V. , Shostak Yu. I.
Published: July 2024

A theoretical description of the photophoretic motion in a viscous nonisothermal binary gas mixture of a large evaporating spherical droplet with significant relative temperature differences in its vicinity is carried out in the quasi-stationary approximation for small Reynolds and Pecle numbers. When describing the properties of a gaseous medium, a power-law type of dependence of the coefficients of molecular transport (viscosity, diffusion and thermal conductivity) and density on temperature was taken into account. Numerical estimates have shown the nonlinear nature of the dependence of the photophoretic force and velocity on the average temperature of the droplet surface.

Authors: Petrov O. A. , Volzhankina K. A.
Published: July 2024

The properties of octa(4-tert-butylphenyl)tetrapyrazinoporphyrazine in 2-methylpyridine were studied. During the acid-base interaction of molecules, a kinetically stable complex was formed with proton transfer. The addition of morpholine, piperidine, n-butylamine, and diethylamine to 2-methylpyridine led to the destruction of this complex, unlike the addition of tert-butylamine and triethylamine. The influence of the proton-accepting ability and spatial structure of the nitrogen-containing base, as well as the basicity of the medium, on the process of the tetrapyrazinoporphyrazine macrocycle decomposition was considered, and a destruction scheme was proposed.

Published: July 2024

Due to a decline in diet quality during adolescence, youth are less likely to consume adequate nutrient dense foods to meet recommended requirements. Iron intake in particular is crucial for healthy physical and brain development in adolescence, but few studies have examined the role of iron intake in adolescents’ behavior problems. The current study examined the associations between iron intake and two types of behavior problems in early adolescents – aggression and rule breaking. The sample included 272 middle school students (Mage =12.08; 53% female; 47% Black, 37% White, 9% Hispanic, 6% other racial/ethnic group). Multivariate regression analyses adjusting for sociodemographic covariates revealed that higher iron intake was linked to lower aggressive behaviors (β = - .16, p < .05), but was not associated with rule breaking. These findings support the role of iron intake in healthy behavioral development in adolescence.

Published: July 2024

We introduce a game where players selfishly choose a resource and endure a cost depending on the number of players choosing nearby resources. We model the influences among resources by a weighted graph, directed or not. These games are generalizations of well-known games like Wardrop and congestion games. We study the conditions of equilibria existence and their efficiency if they exist. We conclude with studies of games whose influences among resources can be modelled by simple graphs.
Optimal Local Identifying and Local Locating-dominating Codes
Authors: Herva Pyry , Laihonen Tero , Lehtilä Tuomo
Published: July 2024

We introduce two new classes of covering codes in graphs for every positive integer r. These new codes are called local r-identifying and local r-locating-dominating codes and they are derived from r-identifying and r-locating-dominating codes, respectively. We study the sizes of optimal local 1-identifying codes in binary hypercubes. We obtain lower and upper bounds that are asymptotically tight. Together the bounds show that the cost of changing covering codes into local 1-identifying codes is negligible. For some small n optimal constructions are obtained. Moreover, the upper bound is obtained by a linear code construction. Also, we study the densities of optimal local 1-identifying codes and local 1-locating-dominating codes in the infinite square grid, the hexagonal grid, the triangular grid and the king grid. We prove that seven out of eight of our constructions have optimal densities.
Global Types and Event Structure Semantics for Asynchronous Multiparty Sessions
Authors: Castellani Ilaria , Dezani-Ciancaglini Mariangiola , Giannini Paola
Published: July 2024

We propose an interpretation of multiparty sessions with asynchronous communication as Flow Event Structures. We introduce a new notion of asynchronous type for such sessions, ensuring the expected properties for multiparty sessions, including progress. Our asynchronous types, which reflect asynchrony more directly and more precisely than standard global types and are more permissive, are themselves interpreted as Prime Event Structures. The main result is that the Event Structure interpretation of a session is equivalent, when the session is typable, to the Event Structure interpretation of its asynchronous type, namely their domains of configurations are isomorphic.
Revisiting the change curve: A rigorous examination and three case studies prompting a re-evaluation of a timeless concept
Authors: Hagemann Michael , Cechlovsky Sascha
Published: July 2024

BACKGROUND: Numerous models of the so called ‘change curve’ exist, yet there is a paucity of scholarly inquiry regarding empirical substantiation, practical implementation, and general applicability.

OBJECTIVE: This study explores the change curve, aiming to examine whether and how the various phases of the curve manifest in a business context, thus assessing their relevance, which represents a novel approach.

METHODS: The analysis, employing a mixed-methods approach of qualitative and quantitative elements, is inductive and interpretative, focusing on exploring and understanding the complexity of the cases. Data collection of this exploratory research was conducted utilizing a multi-faceted approach that included online surveys, semi-structured interviews, on-site observations through Gemba Walks.

RESULTS: A pivotal discovery arises from the validation of the four phases of the change curve. Irrespective of disparate project contexts, individuals manifest akin responses within their respective phases of the change curve, amenable to effective facilitation through judicious interventions. These interventions, derived and systematized from empirical case studies for the first time, underscore their potential utility in guiding individuals through the change process.

CONCLUSIONS: The validation of the four phases and their pragmatic utility warrant further exploration in subsequent scholarly inquiries, aiming to ascertain their robustness across diverse organizational contexts.
Revealing Molecular Patterns of Alzheimer’s Disease Risk Gene Expression Signatures in COVID-19 Brains
Authors: Liu Yan , Xu Weiyue , Yang Pan , Liu Xingshun
Published: July 2024

Background:

Various virus infections are known to predispose to Alzheimer’s disease (AD), and a linkage between COVID-19 and AD has been established. COVID-19 infection modulates the gene expression of the genes implicated in progression of AD.

Objective:

Determination of molecular patterns and codon usage and context analysis for the genes that are modulated during COVID-19 infection and are implicated in AD was the target of the study.

Methods:

Our study employed a comprehensive array of research methods, including relative synonymous codon usage, Codon adaptation index analysis, Neutrality and parity analysis, Rare codon analyses, and codon context analysis. This meticulous approach was crucial in determining the molecular patterns present in genes up or downregulated during COVID-19 infection.

Results:

G/C ending codons were preferred in upregulated genes while not in downregulated genes, and in both gene sets, longer genes have high expressivity. Similarly, T over A nucleotide was preferred, and selection was the major evolutionary force in shaping codon usage in both gene sets. Apart from stops codons, codons CGU – Arg, AUA – Ile, UUA – Leu, UCG – Ser, GUA – Val, and CGA – Arg in upregulated genes, while CUA – Leu, UCG – Ser, and UUA – Leu in downregulated genes were present below the 0.5%. Glutamine-initiated codon pairs have high residual values in upregulated genes. Identical codon pairs GAG-GAG and GUG-GUG were preferred in both gene sets.

Conclusions:

The shared and unique molecular features in the up- and downregulated gene sets provide insights into the complex interplay between COVID-19 infection and AD. Further studies are required to elucidate the relationship of these molecular patterns with AD pathology.

Authors: Kouhnavard Bahram , Khosravi Danesh Mojtaba , Shamsipour Mansour , Mazloumi Adel
Published: July 2024

BACKGROUND: Tea harvesting is a common agricultural occupation, usually conducted in mountainous regions with steep slopes and high altitudes. Despite the utilization of modern technology and mechanized equipment in agriculture, a substantial portion of tea harvesting continues to be traditional and physically strenuous. This dependence on manual labor can lead to a higher likelihood of musculoskeletal disorders among tea harvesting farmers. OBJECTIVE: The objective of this research was investigation of prevalence and risk factors of musculoskeletal disorders in tea harvesting farmers. METHODS: In this review study, we analyzed all published articles on the prevalence and factors influencing musculoskeletal disorders in tea harvesting farmers from March 10, 2010, to November 10, 2023 (last search date). We systematically searched for articles using keywords (risk factor, risk assessment, lower limb, upper limb, musculoskeletal disorders, tea harvesting, posture, manual handling, discomfort, ergonomics, prevalence, farmers) in PubMed, Google Scholar, SID, Web of Science, Scopus, Magiran, Iran Medex, Cochrane Library, and Embase. The quality of the articles was evaluated using the Mixed Methods Appraisal Tool (MMAT), 2018 version. Unrelated articles were excluded following PRISMA statement guidelines, and only articles directly related to the study were reviewed. GraySource and BASE databases were also utilized to identify Gray sources.. RESULTS: Initially, 128 articles were found across different databases, and a total of 17 articles were selected for the final assessment. The primary areas of the body that workers are commonly exposed to musculoskeletal issues are the back, hands, wrists, shoulders, neck, and knees. The research identified four main categories of factors: personal, occupational, environmental, and psychosocial that contribute to musculoskeletal problems. Among these factors are women working in physically demanding environments, lifting heavy bags of harvested tea, time pressures during tea collection, repetitive hand motions from using harvesting tools, the height of the tea plants in the field, working in wet and slippery conditions, uneven ground surfaces, extended working hours, low pay, and lack of support from employers. CONCLUSIONS: Ergonomic interventions such as redesigning tea harvesting tools, enhancing tea plants and workspaces, teaching ergonomic principles of body posture and manual movement, and organizing work with job rotation and adequate rest are recommended to alleviate musculoskeletal disorder symptoms.

The occurrence of geothermal spring not only enhances human health, but also plays a crucial role in generating community’s revenue that boosts up the standard living of locals. An endeavor has been made to delineate the prospective areas of geothermal spring in Kon Tum province, Vietnam by the utilization of joint-geophysical techniques. The blended mode as mentioned is opted for its superiority in providing the rapidassesments of temperature in shallow temperature survey, comprehensive understanding the subsurface structure in electrical resistivity tomography in copporating with the validation in well log interpretation. The results found that the overlapping region of high temperature (35°C) region and low resistivity (200 Ωm) is observed in the east in the vicinity of Dlak Bla river, and it probably broadens to the west of the study area. The outcome of geophysical approaches strongly concur with the well log interpretation, revealing the presence of water-bearing zone encountered in fractured granite. The results also corroborated the existence of concealing fault F5 as a branch of the NE-SW fault F2 which is favorable for creating a route to form the geothermal spring. The output of this research could be considered as an intentive consultation for Kon Tum’s planners and makers on expanding the investigation and exploitation.

Understanding tourism in social farming as a form of social innovation
Authors: Ferrara Annapia
Published: July 2024

Tourism in social farming contexts has important implications for the inclusive development of rural areas. However, current literature on the topic is still scarce and many organizational aspects of this activity are still unexplored. To provide a systematic understanding of the phenomenon, this study presents a literature review to identify tourism in social farming as a form of social innovation. The results of this research reveal how tourism in social farming responds to specific societal challenges, how it fosters social actors' agency and which kind of relationships it stimulates among them. In the end, a comprehensive framework is proposed. Conclusions will detail the theoretical and practical implications of this study while leaving room for reflection on future research.

Culture e pratiche inclusive che emergono dalla cooperazione tra territori comunità e istituti accademici, rappresentano un elemento cruciale sia dal punto di vista concettuale che progettuale per stimolare la nascita di comunità orientate alla promozione dell'educazione. In ragione di ciò, negli ultimi anni, le università italiane hanno assunto questo orizzonte di senso e di intervento nell'ambito delle iniziative ascrivibili alla Terza Missione e all'Impatto Sociale al fine di promuove il valore sociale delle iniziative e, allo stesso tempo, di rendere valutabile l'impatto prodotto da queste ultime in termini di efficacia e di successo per tutti gli attori coinvolti. Da questo punto di vista, l'articolo presenta uno studio di caso di un progetto multi-regione finanziato dal bando "Un passo avanti" promosso dall'Impresa Sociale Con i Bambini avente come obiettivo il sostegno di interventi capaci di innescare processi innovativi, generare nuove relazioni e fornire progetti di impatto sociale per il contrasto alla povertà educativa minorile. I risultati presentati permettono di tracciare alcune utili piste di riflessione e alcuni criteri di intervento per le Università allo scopo di migliorare i processi orientati a promuovere culture e pratiche inclusive in raccordo con le Università, i territori e gli stakeholders locali nella prospettiva di promuovere comunità educanti.

Fare formazione oggi: lo schema di riferimento operativo tra gruppo, transculturalità e istituzione
Authors: Bianchera Luciana , Cavicchioli Giorgio
Published: July 2024

Gli autori trattano il tema del fare formazione negli ambiti gruppali ed istituzionali con un'attenzione specifica a come questi interventi possano essere pensati e declinati nella attuale situazione sociale. Le riflessioni muovono da uno schema di riferimento concettuale e operativo basato sulla psicoanalisi operativa di E. Pichon-Rivière e J. Bleger per la concettualizzazione e l'intervento attraverso i dispositivi gruppali e nei contesti delle istituzioni di cura. La dimensione culturale viene considerata come un aspetto che caratterizza molti contesti del lavoro formativo nella attualità dei servizi psicosociosanitari ed educativi. L'attitudine e la capacità di accogliere il cambiamento da parte degli operatori viene segnalata come una necessità attuale nel lavoro formativo. Ciò presuppone di saper integrare ed evolvere gli schemi di riferimento attraverso i quali operare gli interventi formativi gruppali ed istituzionali. La riflessione proposta tiene anche conto di alcuni movimenti che si riscontrano oggi nell'ambito comunitario, nella Polis all'interno della quale avvengono i processi formativi che coinvolgono gruppi e istituzioni. Si pone così la considerazione per cui la formazione abbia assunto, ancora di più in questi ultimi anni, un ruolo di accoglienza dei dilemmi e dei conflitti soggettivi, intersoggettivi, gruppali ed istituzionali connessi al compito della cura.
Il velo androcentrico. Maschio e femmina tra natura e propaganda
Authors: Gallo Bianca
Published: July 2024

Velo androcentrico è il termine utilizzato da Bruno Bettelheim a indicare quell'atteggiamento universalmente diffuso che tende a considerare di valore le sole attività e vicende maschili, e a offuscare il ruolo del femminile nella storia dell'umanità.Alla luce delle osservazioni di Bettelheim sul ruolo della psicoanalisi, in questo lavoro si intende esaminare quale sia la rappresentazione della relazione maschio/femmina a cui si fa solitamente riferimento. Lo stesso Freud ha ripetutamente auspicato che la biologia in particolare e, più in generale, la ricerca scientifica potesse permettere di fare luce sulle componenti fisiologiche dei processi mentali. Egli sosteneva che poiché non era possibile parlare scientificamente dei sentimenti, pur tentando di descriverne "gli indizi fisiologici", per il momento non si potesse «far altro che attenersi al contenuto rappresentativo che più immediatamente risulta associato al sentimento» (Freud, 1929, p. 558). Le recenti acquisizioni della ricerca scientifica hanno permesso ora di soddisfare, nel suo senso originario, quell'interesse di Freud per la neurologia. Inoltre, seguendo la via indicata da Freud nell'indagare le vicende umane, si farà riferimento alle rappresentazioni dei sentimenti umani presenti nella grande letteratura.
Man(u)tenere i campi gruppali. Conversazione con Stefano Alba sul ruolo dello psicologo in comunità
Authors: Paracchino Cecilia , Carola Davide
Published: July 2024

Il lavoro che segue è il tentativo scritto di dare forma e struttura a oltre tre ore di confronto e dibattito condiviso tra i membri del sottogruppo "Terzo Settore" della sezione Osservatorio di Gruppi e il dott. Stefano Alba1 , soggetto autorevole e storico membro della COIRAG. La conversazione affronta il macro-tema riguardante lo psicologo/psicoterapeuta al lavoro in contesti più "sociali" (comunità, case famiglia, centri diurni, gruppi-appartamento, residenze assistenziali ecc.), che sovente incrociano la strada del giovane laureato in Psicologia e contribuiscono alla sua formazione: quali sono le criticità riscontrabili, le analogie e differenze con il "classico" setting da studio privato, che tipo di apporto terapeutico può essere messo in campo e in che modo, quali sono le dinamiche in gioco. Nelle intenzioni degli autori si è cercato di mantenere quella che a loro avviso è la vera natura del contributo che segue: un lavoro di gruppo, attraverso il gruppo, che grazie agli stimoli e gli spunti del dott. Alba ha potuto dare luce e co-costruire le riflessioni seguenti.  1 Psicologo, psicoterapeuta, gruppoanalista.

L'Italia repubblicana dalla sicurezza marittima stato-centrica a quella postmoderna: studi e prospettive
Authors: De Ninno Fabio
Published: July 2024

La nota prova a tracciare un bilancio e a fornire un primo quadro interpretativo degli studi sulla sicurezza marittima nell'Italia repubblicana. In particolare, cerca di sottolineare il passaggio da una sicurezza centrata su una visione marittima oggetto di una sicurezza nazionale centrata su un modello nazionale a uno internazionale-sovranazionale tipico degli stati postmoderni e frutto dei processi di trasformazione subiti dal mondo marittimo italiano nel periodo della Guerra fredda a causa dei processi di globalizzazione dell'integrazione in sistemi economici e militari come la Cee/Ue e la Nato.

The present (and future) value of the past. Heritage marketing strategies within long-lived firms of Made in Italy
Authors: Riviezzo Angelo , Garofano Antonella , Napolitano Maria Rosaria
Published: July 2024

The present contribution summarizes a research path that started from studies on corporate longevity and came to investigate heritage marketing as a management philosophy and a strategic process aimed at exploiting the organization's historic patrimony as a competitive asset. Our aim as management scholars was to provide an integrated reading of heritage marketing in the context of long-lived firms, where the potential of the past as a strategic resource for present and future success emerges in all its strength. Based on the in-depth analysis of firms that have developed the Made in Italy system over the centuries, we explored heritage marketing from a process view and proposed a model for developing heritage as a key component of identity, positioning, and fu- ture directions. In this article, we argue the complexity of the strategic process aimed at valorizing corporate heritage and highlight the need for integrating the methods typical of busi- ness management and marketing with those deriving from other disciplines. Specif- ically, we propose some reflections on how history-informed research can be used to manage the peculiarities and potential of corporate heritage in long-lived firms
