Incidence and energetics of AGN winds in the distant Universe
No full textThe initial growth phases of active galactic nuclei (AGN) and their central supermassive black holes (SMBHs) are crucial in galaxy evolution, with AGN feedback playing a significant role. However, selecting sources in the feedback phase remains challenging. This thesis focuses on the selection and characterization of AGN in the feedback phase, emphasizing the study of ionized outflows and their impact on host galaxies. The first part presents methods used to isolate ~1400 AGN candidates from the eROSITA Final Equatorial Depth Survey (eFEDS) catalog and the outflow properties derived for a subsample of 23 sources with confirmed ionized winds. For z > 0.5 AGN with detected ionized outflows, we report correlations between mass outflow rate, outflow kinetic power, and AGN bolometric luminosity. However, a weak correlation between maximum outflow velocity and AGN bolometric luminosity highlights the importance of sample selection. Spatially resolved spectroscopic data from MUSE was used to study the morphology and kinematics of ionized gas in a red, obscured quasar within an interacting system. Extended ionized outflows with high velocities and mass outflow rates were observed, likely AGN-driven rather than star formation-driven. However, kinetic coupling efficiencies were low, suggesting the outflows are not energetically significant. Finally, machine learning techniques enhanced AGN selection in the feedback phase. A Random Forest Classifier achieved 95% accuracy in classifying AGNs into feedback and non-feedback phases. This work demonstrates the potential of machine learning in identifying AGN feedback phases in large-scale surveys like eRASS1. This thesis provides insights into the selection, characterization, and impact of AGN outflows on their host galaxies, advancing our understanding of galaxy evolution. Findings suggest that outflows may or may not significantly impact host galaxies, depending on kinetic coupling efficiencies
The criminal protection of the marine environment. Origins, development and protection techniques in the national, supranational and comparative context.
No full textLa ricerca si propone di fornire un contributo allo studio del diritto penale dell’ambiente, prendendo in considerazione la disciplina penalistica che rileva nel caso di offesa – effettiva o potenziale – delle acque marine.
Nello specifico – in ragione dei sempre più frequenti casi di inquinamento e disastro ambientale causati dalle immissioni di sostanze tossiche nelle acque marine, riconducibili alle attività di impresa ed alla navigazione – l’obiettivo del lavoro è quello di soffermarsi, partendo dalla dimensione internazionale ed europea del fenomeno, sulle disposizioni penali vigenti nel nostro ordinamento a salvaguardia delle risorse naturali marine, sulle modalità con cui le stesse sono tipizzate e sui possibili autori di tali reati, valutando – in termini più generali – se sia veramente effettivo l’attuale impianto nazionale di tutela oppure se non sia necessario ripensare il ruolo del diritto penale in tale settore.
Per ampliare il contesto dell’indagine, verrà presa in considerazione la corrispondente disciplina francese, spagnola e statunitense; tale scelta si fonda sulla circostanza che i tre più significativi disastri ambientali marini della storia moderna si sono verificati rispettivamente a largo delle coste bretoni (petroliera Erika), galiziane (nave Prestige) e della Louisiana (piattaforma petrolifera Deep Water Horizon).The research aims to contribute to the study of environmental criminal law, taking into consideration the criminal provisions that are relevant in the case of offense - actual or potential - of marine waters.
Specifically - due to the increasingly frequent cases of pollution and environmental disasters caused by the introduction of toxic substances into marine waters, attributable to business activities and navigation - the purpose of the work is to dwell, starting from the International and European dimension of the phenomenon, on the criminal provisions in force in our legal system for the protection of marine natural resources, on the ways in which they are typified and on the possible perpetrators of these crimes, evaluating - in more general terms - whether the current national system of guardianship or whether it is not necessary to rethink the role of criminal law in this area.
To broaden the context of the investigation, the corresponding French, Spanish and US discipline will be taken into consideration; this choice is based on the fact that the three most significant marine environmental disasters in modern history occurred respectively off the coasts of Breton (tanker Erika), Galicia (ship Prestige) and Louisiana (oil platform Deep Water Horizon)
Housing in the age of circular economy. Models and paradigms for the regeneration of suburbs
No full textIl patrimonio residenziale italiano ammonta a 12,2 milioni di edifici, di cui il 57,5% ha più di 50 anni ed è stato costruito in assenza di normative specifiche, in termini di sicurezza sismica, resistenza al fuoco, efficienza energetica e accessibilità, e manifesta un’avanzata obsolescenza. Agire su questo patrimonio significa operare tramite le due macro categorie di intervento: demolizione/ricostruzione o riqualificazione energetica. Questa ricerca dottorale vuole indagare la demolizione/ricostruzione di comparti urbani periferici, costruiti tra 1945-1965, quale strategia di rigenerazione urbana, integrandola in un modello edilizio basato sui criteri dell’economia circolare. Vengono definite le caratteristiche costruttive e i principi di questo modello di progettazione ecosistemica, denominato Integrho, che coniuga i criteri di ecodesign nel ciclo di vita (Building in Layers, Design for Disassembly e il Design out Waste) con quelli di bioclimaticità e di adattabilità funzionale.
Il lavoro è stato improntato secondo due livelli gerarchici, scala urbana e scala edilizia, tra loro correlate mediante quella intermedia dell’isolato, al fine di ottenere un obiettivo di natura metodologica: definire uno strumento di supporto decisionale, capace di indirizzare tra le categorie di intervento attraverso parametri oggettivi, valutati con analisi comparative speditive. Tale metodologia viene applicata al contesto di Bologna, e si fonda sulla creazione di un’approfondita base conoscitiva attraverso la catalogazione delle 8.209 pratiche edilizie di nuova costruzione presentate tra 1945 e il 1965. Tale strumento georeferenziato, contenente informazioni tipologiche, costruttive ecc., è impiegato per valutare in modo quantitativo e speditivo i consumi energetici, i materiali incorporati, gli impatti ambientali e i costi economici dei differenti scenari di intervento nel ciclo di vita. Infine, l’applicazione del modello edilizio Integrho e del paradigma Ri-Costruire per Ri-Generare ad uno degli isolati periferici selezionati, è impiegata come esemplificazione dell’intero processo, dalla fase conoscitiva a quella strumentale, al fine di verificarne l’attendibilità e l’applicabilità su larga scala.The Italian residential building stock amounts to 12.2 million units, of which 57.5% have more than fifty years and were built without a regulatory framework regarding seismic safety, fire resistance, energy efficiency and accessibility. Nowadays, they show a condition of irreversible obsolescence. How renovate this heritage means choosing between the two macro-categories intervention strategies: demolition/reconstruction or refurbishment. This doctoral research aims to investigate the demolition and reconstruction of residential urban blocks from 1945-1965 as a possible strategy for urban regeneration, integrated with a model based on circular economy principles. The construction characteristics and guidelines of this ecosystemic design model, named Integrho, which combines whole-life-cycle ecodesign criteria (Building in Layers, Design for Disassembly, and Design out Waste) with bioclimatic and functional adaptability criteria, are defined. The work has been structured according to two hierarchical levels: urban scale and building scale; these two levels are mutually connected through the intermediate dimension of the urban block. The methodological goal is to define a decision-support tool that directs between the two macro-categories of intervention: demolition/reconstruction or refurbishment, employing objective parameters assessed through simplified comparative analyses. The methodology is applied to Bologna’s urban area and is founded on creating an in-depth knowledge base by cataloguing the 8.209 residential building permits from 1945 to 1965. This georeferenced tool, containing data, i.e. typology, construction techniques, etc., is employed to estimate the energy consumption, the quantities of construction materials, the environmental impacts and the economic costs of different scenarios in the whole life cycle quantitatively. Finally, the application of the Integrho building model, and the “Reconstruction for Regeneration” paradigm to one of the selected suburban blocks, is used as an exemplification of the entire process, from the knowledge phase to the instrumental one, to verify its reliability and applicability of methodology on a large scale
Einaudi's education. History of the series for children and young adults (1933-1983)
No full textLo scopo del presente lavoro è quello di far emergere gli intenti e i criteri con i quali furono ideate le collane per l’infanzia pubblicate dalla casa editrice Einaudi e di determinare il modello di infanzia pensata come destinataria delle pubblicazioni. Le collane prese in esame nello studio sono state: "Libri per l'infanzia e la gioventù" (1942); "Libri per ragazzi" (1959-1983); "Letture per la scuola media" (1965-1983); "Tantibambini" (1972-78). Oltre alle collane di fiabe da tutto il mondo, non propriamente destinate all’infanzia ma centrali per la riflessione in casa editrice sul tema, è stato anche preso in esame un progetto di pubblicazione mai portato a termine in collaborazione con il Movimento di Cooperazione Educativa che segnò l’inizio del rapporto editoriale tra Mario Lodi e l’Einaudi. La ricerca è frutto dell’esame della documentazione inedita conservata all'Archivio Storico Giulio Einaudi Editore di Torino, con particolare riferimento alla corrispondenza tra autori e redattori. Da un’attenta analisi delle fonti è emerso come i curatori delle collane selezionarono testi lontani da una concezione edulcorata dell’infanzia, ma che, al contrario, portassero nelle case dei lettori personaggi «veri», cioè estremamente realistici e calati nel mondo contemporaneo, con tutte le sue contraddizioni. In controtendenza rispetto alla produzione antecedente e coeva, si invitarono scrittori per adulti a scrivere per l’infanzia, accordando alla letteratura per l’infanzia pari dignità rispetto a quella per adulti, e si proposero temi considerati difficili, presupponendo un’infanzia matura al punto da potersi scontrare con le ingiustizie e le sfide della vita. Importante fu la componente ideologica, genericamente di sinistra, in alcuni casi comunista, che attraversa gran parte delle pubblicazioni prese in esame e che informò le scelte editoriali, in accordo con gli orientamenti della casa, rendendo le collane Einaudi un esempio dell’esito della convergenza tra cultura, pedagogia e letteratura tipico della letteratura per l’infanzia.The purpose of this study is to highlight the intentions and criteria with which the children's series published by the Einaudi publishing house were conceived, and to determine the model of childhood imagined as the target audience for these publications. The series examined in this study include: "Libri per l'infanzia e la gioventù" (1942); "Libri per ragazzi" (1959-1983); "Letture per la scuola media" (1965-1983); "Tantibambini" (1972-78). In addition to the collections of fairy tales from around the world, not strictly intended for children but central to the publisher's reflection on the theme, a publishing project in collaboration with the Cooperative Education Association, which marked the beginning of the editorial relationship between Mario Lodi and Einaudi, was also examined. The research is based on the examination of unpublished documentation preserved at the Historical Archive Giulio Einaudi Editore in Turin, with particular reference to correspondence between authors and editors. A careful analysis of the sources showed that the editors of the series selected texts that were far from a sugar-coated conception of childhood, but rather brought "real" characters into the readers' houses, extremely realistic and immersed in the contemporary world, with all its contradictions. In contrast to previous and contemporary production, adult writers were invited to write for children, granting children's literature equal dignity with adult literature, and proposing difficult topics, assuming the readers as capable of confronting life's injustices and challenges. An important aspect was the ideological component, generally left-wing, sometimes communist, which runs through much of the publications examined and informed editorial choices, in accordance with the publisher's orientations, making the Einaudi series an example of the outcome of the convergence between culture, pedagogy, and literature typical of children's literature
The indigenous peoples displaced by environmental disasters. A study on the impact on the right to religious freedom.
No full textLos pueblos indígenas, tradicionalmente, debido a una combinación de factores históricos, sociales, económicos y ambientales se encuentran en una especial situación de vulnerabilidad. La marginación y discriminación que, generalmente, sufren se plasma en dificultades en los accesos a los servicios más básicos y a oportunidades económicas.
En un contexto mundial en el que los desastres ambientales de desenlace repentinos o de progresión lenta propios del cambio climático están aumentando, los pueblos enraizados en territorios y vinculados íntimamente a un modo de vida a sus recursos naturales se encuentran particularmente afectados. Estos desastres, no solo amenazan la seguridad física y la subsistencia de estas comunidades, sino que, como medida de adaptación adoptada, también los obligan a desplazarse forzosamente en busca de condiciones de vida más seguras integrándose en sociedades ajenas.
Para los pueblos indígenas, este desplazamiento forzado no solo implica la pérdida de sus hogares y medios de vida, sino que también resulta en la ruptura de su conexión espiritual y religiosa con sus territorios ancestrales. Estos territorios no solo son vistos como tierras físicas, sino también como espacios sagrados que albergan la historia, las tradiciones y las creencias espirituales de estos pueblos.
La presente tesis tiene por objetivo analizar la particularidad propia de la espiritualidad indígena, y como el factor religioso se ve afectado debido a un desplazamiento forzoso que, en muchas ocasiones, se convierte en permanente, produciéndose la desvinculación completa de los territorios ancestrales. Es ante esta circunstancia, donde, bajo la luz de los textos internacionales y jurisprudencia, buscamos obtener respuestas y propuestas ante la vulneración del derecho humano a la libertad religiosa, siendo este uno de los principales retos a los que se enfrentan identitariamente los pueblos indígenas, llegando a repercutir en la subsistencia de los mismos.Indigenous peoples, traditionally, due to a combination of historical, social, economic, and environmental factors, find themselves in a particularly vulnerable situation. The marginalization and discrimination they generally suffer manifest in difficulties accessing basic services and economic opportunities.
In a global context where sudden or slow-progressing environmental disasters, characteristic of climate change, are increasing, peoples rooted in territories and intimately linked to a way of life and their natural resources are particularly affected. These disasters not only threaten the physical safety and subsistence of these communities but, as an adaptation measure, also force them to move forcibly in search of safer living conditions, integrating into foreign societies.
For indigenous peoples, this forced displacement not only implies the loss of their homes and livelihoods but also results in the rupture of their spiritual and religious connection with their ancestral territories. These territories are not only seen as physical lands but also as sacred spaces that house the history, traditions, and spiritual beliefs of these peoples.
The purpose of this thesis is to analyze the particularity of indigenous spirituality, and how the religious factor is affected by forced displacement, which often becomes permanent, resulting in the complete disconnection from ancestral territories. It is in this circumstance, under the light of international texts and jurisprudence, that we seek to obtain responses and proposals regarding the violation of the human right to religious freedom, which is one of the main challenges faced by indigenous peoples identitarily, ultimately impacting their subsistence.I popoli indigeni, tradizionalmente, a causa di una combinazione di fattori storici, sociali, economici e ambientali, si trovano in una particolare situazione di vulnerabilità. La marginalizzazione e la discriminazione che, generalmente, subiscono si manifestano in difficoltà nell'accesso ai servizi più basilari e alle opportunità economiche
In un contesto mondiale in cui i disastri ambientali, sia di natura improvvisa che progressiva, propri del cambiamento climatico, stanno aumentando, i popoli radicati nei territori e intimamente legati a un modo di vita e ai loro risorse naturali sono particolarmente colpiti. Questi disastri minacciano non solo la sicurezza fisica e la sopravvivenza di queste comunità, ma, come misura di adattamento adottata, li costringono anche a spostarsi forzatamente in cerca di condizioni di vita più sicure integrandosi in società estranee.
Per i popoli indigeni, questo spostamento forzato non comporta solo la perdita delle loro case e mezzi di sostentamento, ma comporta anche la rottura del loro legame spirituale e religioso con i loro territori ancestrali. Questi territori non sono solo visti come terre fisiche, ma anche come luoghi sacri che custodiscono la storia, le tradizioni e le credenze spirituali di questi popoli.
La presente tesi si propone di analizzare la particolarità propria della spiritualità indigena e come il fattore religioso viene influenzato da uno spostamento forzato che, in molte occasioni, diventa permanente, provocando il distacco completo dai territori ancestrali. In questa circostanza, alla luce dei testi internazionali e della giurisprudenza, cerchiamo di ottenere risposte e proposte di fronte alla violazione del diritto umano alla libertà religiosa, che è una delle principali sfide identitarie affrontate dai popoli indigeni, con ripercussioni sulla loro stessa sopravvivenza
Studies on Procopius of Caesarea's Anecdota: a linguistic and stylistic commentary on Proc. An. 1-12.
No full textLa tesi consiste in un saggio di commento ai primi dodici capitoli degli Anecdota di Procopio di Cesarea, preceduto da uno studio d’inquadramento generale sull’autore e l’opera.
Sebbene negli ultimi anni l’attenzione sull’autore sia particolarmente viva, un commento agli Anecdota risulta tuttora assente. Nell’impossibilità di commentare in maniera capillare ed esaustiva, nel corso dei tre anni di dottorato, l’intera opera nei suoi trenta capitoli, si è ridotto il campo d’indagine ai primi dodici, culminanti con la cosiddetta demonologia, apice dell’invettiva procopiana. L’elaborato si apre con uno studio introduttivo che contestualizza l’opera, affronta le questioni più dibattute (e.g. datazione, genere, affidabilità, etc.), approfondisce i temi principali e problematizza l’aspetto linguistico-stilistico, non esauribile, contrariamente all’opinione più diffusa, in una mera forma di purismo. Segue il testo greco, secondo l’edizione critica più recente (Mihăescu 1972), corredato da traduzione a fronte; sono elencati nel saggio introduttivo tutti i passi in cui ci si discosta dall’edizione di riferimento. Il commento vero e proprio a Proc. An. 1-12 è articolato per lemmi: l’analisi, pur non tralasciando la prospettiva storica, si concentra sulla dimensione filologica, testuale, stilistica e letteraria. L’attenzione particolare riservata alla lingua permette di cogliere le continuità all’interno dell’eterogenea produzione procopiana e apre a una comprensione più profonda dell’opera, della sua ideologia e del suo contesto.The dissertation consists of a commentary on the first twelve chapters of Procopius of Caesarea's Anecdota, preceded by a general study on the author and the work. Although scholarly attention on the author has increased in recent years, a commentary on the Anecdota is still a desideratum.
The dissertation opens with an introductory study that contextualizes the work, addresses the most debated issues (e.g., dating, genre, reliability, etc.), and problematizes the linguistic-stylistic aspects; it includes the Greek text, based on the most recent critical edition (Mihăescu 1972), along with a facing translation. The Greek text follows, according to the most recent critical edition (Mihăescu 1972), accompanied by a facing translation; in the introductory essay, all the passages deviating from the reference edition are listed. The commentary on Proc. An. 1-12 is structured by lemmata: the analysis, while not neglecting the historical perspective, focuses on the philological, textual, stylistic, and literary dimensions.
The particular attention given to language reveals ongoing themes within Procopius's heterogeneous production and opens up a deeper understanding of the Anecdota, its ideology, and its context
La democrazia deliberativa negli Stati Uniti: teoria e prassi
No full textThis dissertation aims to analyse the development of the deliberative model of democracy in the U.S., both in an empirical and theoretical levels, from its origins in the eighties of the last century until now.
In the first part we study the political and historical elements that build the crisis of the Liberal political system in the seventies in the U.S. and its effects on the political behaviour of citizens.
In the second part we discuss the origins and development of the deliberative theory of democracy, its main authors, approaches and elements. The key aspect of this model of democracy is to reverse the apathy and strength the political participation of citizens through public deliberation.
In the last part we expose the practical level of the deliberative democracy: how this theory of has been put into practice in the American political domain. We describe the main projects of deliberative democracy rose from civil society from the eighties until today. Finally, we expose the James Fishkin’s proposal of deliberative poll. This is the link between the empirical and theoretical levels of the deliberative model of democracy
Integrated approaches for tailoring risk assessment in potential or confirmed BRCA1/2 variant carriers
No full textBackground
Prompt and proper identification of germline BRCA1/2 pathogenic variants (PVs) is essential to inform clinical decisions in breast cancer/ovarian cancer (BC/OC) patients and their families.
Aim
To improve identification and risk assessment of germline BRCA1/2 PV carriers.
Materials and Methods
Study_1: The recent ClinGen ENIGMA BRCA1/2 classification criteria were systematically applied to all the BRCA1/2 variants of uncertain significance (VUS) identified in our laboratory.
Study_2: Pathogenicity and associated penetrance of the Italian founder BRCA1:c.5017_5019del(p.His1673del) variant were assessed by combining data from 72 Italian carrier families and additional sources.
Study_3: Clinical-pathological features of OC patients associated with germline BRCA1/2 PVs were identified through a systematic literature review with meta-analysis and analyzed using logistic regression models and machine learning approaches in a series of 1009 OC patients to develop a risk score.
Results
Study_1: 135 out of 166 (81.3%) VUS detected in 231 index cases were re-classified: 128 (94.8%) as Benign/Likely Benign and 7 (5.2%) as Pathogenic/Likely Pathogenic.
Study_2: BRCA1:c.5017_5019del(p.His1673del) variant carriers displayed significantly increased risk for OC (HR = 33.0, 95%) and uterine cancer (HR = 8.0), but not for BC (HR = 0.7). The variant was classified as Pathogenic for different types of evidence.
Study_3: The systematic literature review with meta-analysis and the analysis of our OC cohort showed that histotype, family history of BC/OC, previous BC and age at diagnosis are independently and significantly associated with BRCA1/2 status. ORs derived from multivariable logistic regression calibrated according to machine learning analyses results were used to assign weights from 1 to 3 to each feature, developing a score ranging from 0 to 10 associated with increasing risk of BRCA1/2 PVs (score 0 =0.6%; score ≥7 =88%).
Conclusions
These results are relevant for a significant number of patients and families and could make their clinical management more precise and effective
Cardiac amyloidosis: hemodynamic profile and prognostic implications
No full textBackground: Cardiac amyloidosis (CA) is a hypertrophic phenotype cardiomyopathy characterized by a clinical presentation predominantly defined by heart failure. This study evaluates the invasive hemodynamic characteristics and their prognostic implications in consecutive patients diagnosed with CA (in its three main etiologies: light chain amyloidosis AL, transthyretin variant amyloidosis ATTRv, and transthyretin wild-type amyloidosis ATTRwt) who underwent RHC at IRCCS S. Orsola Hospital in Bologna between 1992 and December 2023.
Results: A total of 274 patients were enrolled (121 [44.2%] AL, 66 [24.1%] ATTRv, and 87 [31.7%] ATTRwt). At baseline, the hemodynamic profile was characterized by elevated biventricular filling pressures and pulmonary hypertension, with a median mean pulmonary artery pressure (mPAP) of 24 mmHg [IQR: 18–30], predominantly post-capillary or combined pre- and post-capillary. The stroke volume index (SVi) was reduced, with a median of 30 mL/m² [IQR: 24–37], and the cardiac index (CI) was at the lower limit of normality, with a median of 2.4 L/min/m² [IQR: 1.9–2.8]. Patients with advanced NYHA class at presentation (III/IV) presented a more severe echocardiographic and hemodynamic profile. Invasive hemodynamic parameters showed a good correlation with echocardiographic measurements. During a median follow-up of 30 months, 159 deaths were recorded. Classic cut-offs for RAP, PCWP, mPAP, and SVi emerged as predictors of mortality in Kaplan-Meier curves. In multivariate Cox regression analysis, independent predictors of overall mortality included age at diagnosis, AL etiology, advanced NYHA functional class at presentation (III/IV), estimated glomerular filtration rate (eGFR), RAP, and SVi.
Conclusions: The hemodynamic profile of patients with cardiac amyloidosis is characterized by concomitant systolic and diastolic dysfunction, elevated biventricular filling pressures, and reduced SVi. Both RAP and SVi are independently associated with mortality in this population
The dark and bright side of remote work: social isolation, concentration, and performance of remote workers
No full textThis dissertation, comprised of three separate studies, focuses on the relationship between remote work adoption and employee job performance, analyzing employee social isolation and job concentration as the main mediators of this relationship. It also examines the impact of concern about COVID-19 and emotional stability as moderators of these relationships. Using a survey-based method in an emergency homeworking context, the first study found that social isolation had a negative effect on remote work productivity and satisfaction, and that COVID-19 concerns affected this relationship differently for individuals with high and low levels of concern. The second study, a diary study analyzing hybrid workers, found a positive correlation between work from home (WFH) adoption and job performance through social isolation and job concentration, with emotional stability serving respectively as a buffer and booster in the relationships between WFH and the mediators. The third study, even in this case a diary study of hybrid workers, confirmed the benefits of work from home on job performance and the importance of job concentration as a mediator, while suggesting that social isolation may not be significant when studying employee job performance, but it is relevant for employee well-being. Although each study provides autonomously a discussion and research and practical implications, this dissertation also presents a general discussion on remote work and its psychological implications, highlighting areas for future researchQuesto lavoro di tesi dottorale, composto da tre diversi studi, si è concentrato sul rapporto tra adozione del lavoro a distanza e performance dei lavoratori, analizzando come mediatori principali di questa relazione l'isolamento sociale dei dipendenti e la concentrazione sul lavoro. Ha inoltre esaminato l'impatto delle preoccupazioni per il COVID-19 e della stabilità emotiva come moderatori di alcune delle relazioni testate. Il primo studio, utilizzando un questionario e focalizzandosi sul lavoro remoto emergenziale, ha trovato che l'isolamento sociale ha avuto un impatto negativo sulla produttività e la soddisfazione del lavoro a distanza e che le preoccupazioni per il COVID-19 hanno influito sulla relazione in modo diverso per i lavoratori con alti e bassi livelli di preoccupazione. Il secondo studio, uno studio di diario che analizzava un contesto di lavoro ibrido, ha trovato una correlazione positiva tra l'adozione del lavoro da casa (WFH) e la performance sul lavoro, quando isolamento sociale e concentrazione sul lavoro venivano considerati come mediatori. Inoltre, ha trovato che la stabilità emotiva fungeva da cuscinetto o amplificatore nei rapporti tra WFH e i mediatori menzionati. Il terzo studio, anche in questo caso uno studio di diario in un contesto di lavoro ibrido, ha confermato i vantaggi del lavoro a distanza sulla performance lavorativa e la significatività della concentrazione sul lavoro come mediatore. Inoltre, ha aperto la strada alla considerazione per la quale l'effetto dell’isolamento sociale è da ritenersi non significativo nello studio della performance lavorativa dei dipendenti, sebbene rilevante per il loro benessere. Anche se ogni studio fornisce in esso discussioni e implicazioni di ricerca e pratiche, questo lavoro di tesi si conclude con una discussione generale sul tema del lavoro a distanza e i correlati psicologici che comporta, e fornisce alcuni punti di attenzione per la ricerca futura
