<p>U ovoj doktorskoj disertaciji prikazana je koncepcija, realizacija i potvrda nove metode<br />jednovremenog etaloniranja strujnih mernih transformatora sa dve različite merne<br />aparature. Pregledom stručne literature ne postoji podatak da je ova metoda ranije<br />primenjivana. U disertaciji su prikazane različite merne metode za ispitivanje i<br />etaloniranje mernih transformatora koje imaju primenu u savremenoj praksi i koje<br />podrazumevaju i različite merne mogućnosti. Takođe je i ekperimentalno potvrđeno<br />jednovremeno ispitivanje i etaloniranje strujnih mernih transformatora sa nekoliko<br />mernih aparatura koje su zasnovane na različitim metodama. Sprovedna istraživanja i<br />eksperimentalni rezultati pokazuju i potvrđuju niz prednosti ovakvog načina<br />etaloniranja. Detaljna analiza komponenti merne nesigurnosti pokazala je da se<br />primenom ove metode postiže poboljšanje merne nesigurnost etaloniranja za skoro red<br />veličine u odnosu na klasično pojedinačno etaloniranje sa dve različite merne<br />aparature. Analiza uticajnih veličina na mernu nesigurnost pokazuje da se po ovoj novoj<br />metodi etaloniranja eliminiše niz komponenti od kojih su najznačajnije: uticaj<br />nejednakosti referentnih struja i ispitnog opterećenja. Istraživanja su takođe pokazala<br />da jednovremena metoda osim što doprinosi podizanju tačnosti etaloniranja strujnih<br />transformatora, ima primenu i u etaloniranju mernih aparatura za ispitivanje tačnosti<br />mernih transformatora i interkonparaciji strujnih etalon transformatora. Kroz<br />konkretne primere realizovane u praksi, razmotreni su i prikazani načini etaloniranja<br />mernih aparatura za ispitivanje tačnosti ovom novom metodom. Interkomparacijom dva<br />merna sistema visoke klase tačnosti Nacionalnog merološkog instituta Kanade<br />(National Research Council Canada), od kojih je jedna razvijena u Elektrotehničkom<br />Institutu &quot;Nikola Tesla&quot;, pokazana je i prednost primene jednovremene metode u oblasti<br />primarne metrologije strujnih mernih transformatora.</p> / <p>The dissertation presents the concept, its realisation and verification of the new method<br />of simultaneous comparison of the current transformers by two different measuring<br />apparatus. It is shown by searching the literature, that this method has not been used<br />before. In this dissertation different measuring methods for testing and calibration of<br />current transformers, with their different measuring capabilities are presented. Most of<br />them have been used in recent practice. Furthermore, the experimental verification of<br />new simultaneous calibration method is presented. For this reason some measuring<br />apparatus based on different measuring methods were used. Conducted research and<br />experimental results confirmed a number of advantages of this calibration method.<br />Detailed analysis of the components of the uncertainty of measurements shown that<br />using simultaneous method uncertainty of measurements have been improved<br />comparing to method with two individual calibration by different apparatus. In that case<br />some of the measuring uncertainty components can be neglected. The most significant<br />is component caused by variation of referent current and component caused by variation<br />of burden. The research has also showed that simultaneous method can be used for<br />calibration of measuring apparatus for current transformer accuracy testing and their<br />inter-comparisons. The ways of calibration of apparatus for current transformer accuracy<br />testing are considered and presented, through concrete examples realized in practice.<br />A high-accuracy comparison of two NRC (National Research Council Canada)<br />calibration systems were carried out by new simultaneous method. One measuring<br />system is developed at Electrical Engineering institute Nicola Tesla, Belgrade.<br />Accordingly the advantage of simultaneous method applied at the primary metrology of<br />current transformer is verified.</p>

<p>The primary objective of this research was to identify and<br />analyse the challenges faced by ethnic minority students<br />while studying and building an academic career in the higher<br />education system of Serbia. The secondary objective was to<br />analyse the unconscious and conscious gender biases towards<br />ethnic minority women, when building their academic careers<br />and in reaching decision-making position in academia. The<br />tertiary objective of was to raise awareness about the<br />increased demand for human resources in the technical fields<br />and that therefore more women should be steered towards the<br />studying engineering.<br />The research was conducted based on 2192 filled in<br />questionnaires and 45 semi-structured interviews. The<br />research results showed that language, intersecting with<br />gender, ethnicity and class result in a new inequality concept.<br />It was shown that women are under-represented in technical<br />fields, which has its roots in gender stereotypes. Finally, it<br />was shown that women are less motivated to reach higher<br />positions in the Serbian higher education system than men.<br />The author proposes a set of policy recommendations for<br />solving/mitigating the identified challenges, e.g. deconstruction<br />of gender stereotypes via improved teaching<br />aids in elementary and high schools, optimised Serbian<br />language teaching to eliminate the language difficulty faced<br />at the start of their higher education; as well as the founding<br />of an ethnic minority research centre, which would research<br />the challenges faced by ethnic minority communities.</p> / <p>Primarni cilj istraživanja je identifikacija i i analiza prepreka<br />u sistemu visokog obrazovanja tokom studiranja i izgradnje<br />karijere u akademskoj zajednici žena iz nacionalnih zajednica<br />sa posebnim osvrtom na žene iz mađarske nacionalne<br />zajednice. Sekundarni cilj je analiza nesvesne i svesne rodne<br />pristrasnosti prema ženama etničkih manjina u toku izgradnje<br />akademske karijere i pri dosezanju visokih pozicija unutar<br />akademije. Tercijarni cilj istraživanja je podizanje svesti o<br />tome, kako je potražnja za ljudskim resursima na trži&scaron;tu rada<br />u oblasti tehničkih nauka značajna i da je stoga potrebno<br />usmeriti veći broj žena ka tim oblastima. Istraživanje je<br />sprovedeno pomoću 2192 popunjena upitnika i 45 polustrukturirana<br />intervjua. Istraživanjem je utvrđeno da jezik,<br />koji je u intersekciji sa rodom, nacionalno&scaron;ću i klasom,<br />rezultira novim konceptom nejednakosti. Takođe je dokazano<br />da su žene nedovoljno zastupljene u tehničkim oblastima, &scaron;to<br />je najvećim delom moguće pripisati rodnim stereotipima.<br />Konačno, utvrđeno je da su žene manje motivisane da<br />dosegnu visoke pozicije od mu&scaron;karaca u sistemu visokog<br />&scaron;kolstva. Autorka predlaže skup mera za re&scaron;avanje i/ili<br />ublažavanje identifikovanih izazova, npr. dekonstrukcija<br />rodnih stereotipa pomoću unapređenih nastavnih materijala u<br />osnovnim i srednjim &scaron;kolama, prilađen program učenja<br />srpskog jezika za učenike iz etničkih manjina sa ciljem<br />izbegavanja jezičke barijere na početku studija; odnosno<br />osnivanje centra za istraživanje statusa i izazova zajednica<br />etničkih manjina.</p>

<p>The research work carried out in this thesis is aimed&nbsp;&nbsp; at fuzzifying algebraic and relational structures in the framework of Ω-sets, where Ω is a complete lattice.<br />Therefore we attempt to synthesis universal algebra and fuzzy set theory. Our&nbsp; investigations of Ω-algebraic structures are based on Ω-valued equality, satisability of identities and cut techniques. We introduce Ω-algebras, Ω-valued congruences,&nbsp; corresponding quotient&nbsp; Ω-valued-algebras and&nbsp; Ω-valued homomorphisms and we investigate connections among these notions. We prove that there is an Ω-valued homomorphism from an Ω-algebra to the corresponding quotient Ω-algebra. The kernel<br />of an Ω-valued homomorphism is an Ω-valued congruence. When dealing with cut structures, we prove that an Ω-valued homomorphism determines classical homomorphisms among the corresponding quotient structures over cut&nbsp; subalgebras. In addition, an&nbsp; Ω-valued congruence determines a closure system of classical congruences on cut subalgebras. In addition, identities are preserved under Ω-valued homomorphisms. Therefore in the framework of Ω-sets we were able to introduce Ω-attice both as an ordered and algebraic structures. By this Ω-poset is defined as an Ω-set equipped with&nbsp; Ω-valued order which is&nbsp; antisymmetric with respect to the corresponding Ω-valued equality. Thus defining the notion of pseudo-infimum and pseudo-supremum we obtained the definition of Ω-lattice as an ordered structure. It is also defined that the an Ω-lattice as an algebra is a bi-groupoid equipped with an Ω-valued equality fulfilling some particular lattice Ω-theoretical formulas. Thus using axiom of choice we proved that the two approaches are equivalent. Then we also introduced the notion of complete Ω-lattice based on Ω-lattice. It was defined as a generalization of the classical complete lattice.<br />We proved results that characterizes Ω-structures and many other interesting results.<br />Also the connection between Ω-algebra and the notion of weak congruences is presented.<br />We conclude with what we feel are most interesting areas for future work.</p> / <p>Tema ovog rada je fazifikovanje algebarskih i relacijskih struktura u okviru omega- skupova, gdeje Ω kompletna mreza. U radu se bavimo sintezom oblasti univerzalne algebre i teorije rasplinutih (fazi) skupova. Na&scaron;a istraživanja omega-algebarskih struktura bazirana su na omega-vrednosnoj jednakosti,zadovoljivosti identiteta i tehnici rada sa nivoima. U radu uvodimo omega-algebre,omega-vrednosne kongruencije, odgovarajuće omega-strukture, i omega-vrednosne homomorfizme i istražujemo veze izmedju ovih pojmova. Dokazujemo da postoji Ω -vrednosni homomorfizam iz Ω -algebre na odgovarajuću količničku Ω -algebru. Jezgro Ω -vrednosnog homomorfizma je Ω- vrednosna kongruencija. U vezi sa nivoima struktura, dokazujemo da Ω -vrednosni homomorfizam odredjuje klasične homomorfizme na odgovarajućim količničkim strukturama preko nivoa podalgebri. Osim toga, Ω-vrednosna kongruencija odredjuje sistem zatvaranja klasične kongruencije na nivo podalgebrama. Dalje, identiteti su očuvani u Ω- vrednosnim homomorfnim slikama.U nastavku smo u okviru Ω-skupova uveli Ω-mreže kao uredjene skupove i kao algebre i dokazali ekvivalenciju ovih pojmova. Ω-poset je definisan kao Ω -relacija koja je antisimetrična i tranzitivna u odnosu na odgovarajuću Ω-vrednosnu jednakost. Definisani su pojmovi pseudo-infimuma i pseudo-supremuma i tako smo dobili definiciju Ω-mreže kao uredjene strukture. Takodje je definisana Ω-mreža kao algebra, u ovim kontekstu nosač te strukture je bi-grupoid koji je saglasan sa Ω-vrednosnom jednako&scaron;ću i ispunjava neke mrežno-teorijske formule. Koristeći aksiom izbora dokazali smo da su dva pristupa ekvivalentna. Dalje smo uveli i pojam potpune Ω-mreže kao uop&scaron;tenje klasične potpune mreže. Dokazali smo jo&scaron; neke rezultate koji karakteri&scaron;u Ω-strukture.Data je i veza izmedju Ω-algebre i pojma slabih kongruencija.Na kraju je dat prikaz pravaca daljih istrazivanja.</p>

Therefore, it is necessary to use methods that can measure these curvatures with good accuracy levels. The preparation of a glide path prior to root canal instrumentation is widely suggested because can avoid possible operative errors, such as loss of centralization and apical transportation, especially in curved root canals. There is no consensus concerning the methods that can be used to measure radicular curvatures, nor regarding the efficacy of glide path. The present investigation has the objective of performing two systematic reviews in order to answer the following questions: 1- What are the methods, described in the literature, used to measure the angles and other characteristics of the curvatures of the root canals? 2- The glide path is able to reduce the apical transportation and the loss of centralization of the endodontic preparation? Also, how does the glide path - manual or engine-driven - result in minor operative errors? Methods: Using the appropriate terms for each review, electronic searches were performed on six databases: PubMed, PubMed Central (PMC), Embase, Scopus, EBSCO Dentistry & Oral Sciences Source (DOSS) and Virtual Health Library (VHL). We used studies published in English or in any language with Latin alphabet. There was no time limit for publications. In addition, in the second review, the included studies, the risk of biases was analyzed. Results: In review 1, about the methods of measurement of curvatures, 6,336 studies were obtained and of these, 31 articles that described innovative methods. Eleven studies described the methods used to measure only the angle of the radicular curvatures, for which they used 2D images. 13 studies also used 2D images, however, in addition to the angles, evaluated other features of the root canal curvatures (position, length, direction, height and shape). In addition, seven studies evaluated curvatures using 3D methods. In review 2, regarding glide path, 2,146 articles were obtained, and 18 studies fulfilled the inclusion criteria, composing the final analysis. 9 studies evaluated the glide path per se and 11 evaluated the impact of glide path on final engine-driven endodontic preparation. Conclusion: Revision 1 suggested that most methods for root canal curvature measurement have potential clinical applications; however, there is a lack of consensus on the ideal technique. In addition to the angle, other features, such as radius and position of curvature, need to be measured and should be considered when evaluating root canal curvature in both clinical and research purposes. Revision 2 revealed that engine-driven confection of glide path, when compared to manual, presents similar or better results of apical transportation and maintenance of root canal centralization. It was also observed that the preparation of glide path, prior to endodontic preparation, is associated with similar results or with a reduction of the apical transportation and the maintenance of the preparation centralization. It was also observed that deviations occur in all situations. / A grande maioria dos condutos apresenta curvaturas e o conhecimento destas curvaturas permite ao cl?nico uma melhor escolha da terap?utica endod?ntica. Para tanto, faz-se necess?rio o emprego de m?todos que possam medir essas curvaturas com bons n?veis de acur?cia. A confec??o de um glide path pr?vio ? instrumenta??o dos canais radiculares ? amplamente sugerida, pois pode evitar poss?veis erros operat?rios, tais como a perda de centraliza??o do preparo e o transporte apical, especialmente em canais radiculares curvos. Como n?o h? consenso quanto aos m?todos que podem ser utilizados na medi??o das curvaturas radiculares, tampouco referente a efic?cia do glide path, a presente investiga??o tem o objetivo de realizar duas revis?es sistem?ticas, a fim de responder ?s seguintes quest?es: 1- Quais s?o os m?todos, descritos na literatura, empregados na mensura??o dos ?ngulos e demais caracter?sticas das curvaturas dos canais radiculares? 2- O glide path ? capaz de reduzir o transporte apical e a perda de centraliza??o do preparo endod?ntico? Al?m disso, qual a forma de confec??o do glide path ? manual ou motorizada ? resulta em menores erros operat?rios? M?todos: Utilizando os termos apropriados para cada revis?o, foram realizadas buscas eletr?nicas em seis bases de dados: PubMed, PubMed Central (PMC), Embase, Scopus, EBSCO Dentistry & Oral Sciences Source (DOSS) e Virtual Health Library (VHL). Foram utilizados estudos publicados em ingl?s ou em qualquer idioma com alfabeto latino n?o houve qualquer limite temporal para as publica??es. Al?m disso, na segunda revis?o, os estudos inclu?dos tiveram o risco de vieses analisado. Resultados: Na revis?o 1, acerca dos m?todos de mensura??o das curvaturas, foram obtidos 6.346 estudos e destes, restaram 31 artigos que descreviam m?todos inovadores. Onze estudos foram descritos a fim de mensurar apenas o ?ngulo das curvaturas radiculares, para isso utilizaram 9 imagens em 2D. 13 estudos utilizaram tamb?m imagens em 2D, entretanto, al?m dos ?ngulos avaliaram outras caracter?sticas das curvaturas dos canais radiculares (posi??o, comprimento, dire??o, altura e forma). Al?m disso, sete estudos avaliaram as curvaturas atrav?s de m?todos em 3D. J? na revis?o 2, a respeito do glide path, obteve-se 2.146 artigos, sendo que 18 estudos preencheram os crit?rios de inclus?o, compondo a an?lise final. 9 pesquisas avaliaram a confec??o do glide path per se e 11 avaliaram a repercuss?o do glide path no preparo endod?ntico motorizado final. Conclus?o: a revis?o 1 sugeriu que a maioria dos m?todos de mensura??o de curvaturas dos canais radiculares tem potenciais aplica??es cl?nicas, no entanto, h? uma falta de consenso sobre a t?cnica ideal. Al?m do ?ngulo, outros fatores, como raio e posi??o da curvatura, precisam ser mensurados e devem ser levados em considera??o ao se avaliar a curvatura do canal radicular tanto em tratamentos cl?nicos como em ambientes de pesquisa. J? a revis?o 2 revelou que a confec??o motorizada, quando comparada com a confec??o manual, do glide path apresenta resultados similares ou melhores de transporte apical e manuten??o da centraliza??o do canal radicular. Observou-se, tamb?m, que a confec??o do glide path, previamente ao preparo endod?ntico, est? associada com resultados similares ou com a redu??o do transporte apical e a manuten??o da centraliza??o do preparo. Tamb?m foi observado que ocorrem desvios em todas as situa??es.

Job crafting consists of informal individual initiatives to modify the work, in order to optimize resources and demands and or to make it more engaging and rewarding. Individuals shape their work experience through actions that redefine the tasks and relationships involved in the work, as well as through cognitive changes in the way they perceive work. The theoretical model of job crafting proposes that such actions take place at different organizational contexts and are independent of the degree of autonomy, complexity and authority involved in each work. Since its emergence in the qualitative research in 2001, the proactive approach of job crafting has attracted growing interest from researchers and practitioners, as an alternative that explains and highlights the energetic and daily efforts of the individual to change their working environment. In Brazil, research in job crafting is at an early stage. Five different interconnected studies were undertaken to deepen the theoretical and empirical knowledge about job crafting and to advance its research in Brazil. The first study presents a systematic review of the international scientific literature on job crafting. Evidences revealed an increase of scientific publications about the construct, driven by the development of measures. We found a lack of production in our context and the need to adapt measures to assess the construct and promote empirical research about job crafting in Brazil. The second study, which theoretically introduces the theme, aimed to meet the need to contribute to a chapter about job crafting for book to be published in Brazil. The chapter situates the job crafting approach, revises its conceptualization in the international literature, describes the state of the art in the evaluation of the construct, portrays the main antecedents and outcomes of job crafting according to recent empirical studies and discusses some benefits and practical implications. The third study presents the adaptation and validation of the Job Crafting Questionnaire to the Brazilian context. We conducted two studies with professionals in Brazil to investigate the internal structure of the instrument through exploratory and confirmatory techniques. The results indicated that the instrument presented adequate psychometric characteristics, being a valid measure for assessing job crafting in general populations in Brazil. The fourth study presents a systematic review and a meta-analysis on the relationship between job crafting and well-being. The positive relationship between both constructs was corroborated. We found that the job crafting has a greater effect on the positive dimension of the well-being. This study also brought evidences of a significant difference between the effect of job crafting on occupational and general well-being measures, indicating a better performance of the latter. Finally, we undertook an exploratory study about the job demands-resources model in the Brazilian context. Drawing on the network analysis technique, we investigated the relationships between the variables of working conditions, work engagement, job crafting and well-being, predicted by the job demands-resources model. Results supported some relationships predicted by the theoretical model. However, the job crafting, which predicted work engagement, did not happen at the expenses of the working conditions (resources and demands). This finding indicates the need to investigate other intrinsic precedents of job crafting. These five products of the master?s thesis advance research in job crafting in Brazil. / A tem?tica central da presente disserta??o s?o os comportamentos proativos no trabalho denominados de job crafting. Tais comportamentos consistem em iniciativas individuais informais que buscam modificar o trabalho, para otimizar seus recursos e demandas e ou para torn?-lo mais envolvente e gratificante. Os indiv?duos moldam sua experi?ncia de trabalho atrav?s de a??es que redefinem as tarefas e as rela??es envolvidas no trabalho, bem como por meio de mudan?as cognitivas na forma de perceber o seu trabalho. O modelo te?rico do job crafting prop?e que tais a??es acontecem em diferentes contextos organizacionais e s?o independentes do grau de autonomia, complexidade e autoridade envolvidos no trabalho. Desde o seu surgimento na pesquisa qualitativa em 2001, a perspectiva proativa do job crafting tem despertado crescente interesse de pesquisadores e profissionais, como uma alternativa que explica e salienta os esfor?os proativos e cotidianos do indiv?duo para alterar seu contexto de trabalho. No Brasil, a pesquisa em job crafting encontra-se em est?gio inicial. Foram empreendidos cinco estudos diferentes e interconectados que buscaram aprofundar o conhecimento te?rico e emp?rico sobre o job crafting e avan?ar sua pesquisa no Brasil. O primeiro estudo apresenta uma revis?o sistem?tica da produ??o cient?fica internacional sobre o job crafting. Verificou-se um crescimento de publica??es cient?ficas sobre o construto, impulsionado pelo desenvolvimento de medidas. Constatou-se a aus?ncia de produ??o no nosso contexto e a necessidade de adaptar medidas para aferir o construto e impulsionar a pesquisa emp?rica sobre o job crafting no Brasil. O segundo estudo introduz teoricamente a tem?tica e objetivou atender ? necessidade de contribuir com um cap?tulo sobre job crafting para um livro ainda in?dito no Brasil1. O cap?tulo situa a abordagem do job crafting, revisa sua conceptualiza??o na literatura internacional, descreve o estado da arte na avalia??o do construto, retrata os principais antecedentes e desfechos do job crafting de acordo com recentes estudos emp?ricos, e discute alguns benef?cios e implica??es pr?ticas. O terceiro estudo apresenta a adapta??o e valida??o do Job Crafting Questionnaire para o contexto brasileiro. Conduziu-se dois estudos com profissionais no Brasil para investigar a estrutura interna do instrumento por meio de t?cnicas explorat?rias e confirmat?rias. Os resultados indicaram que o instrumento apresentou caracter?sticas psicom?tricas adequadas, sendo uma medida v?lida para avalia??o do job crafting em popula??es gerais no Brasil. O quarto estudo apresenta uma revis?o sistem?tica e uma metan?lise sobre a rela??o do job crafting com o bem-estar. Corroborou-se a rela??o positiva entre ambos construtos. Constatou-se um maior efeito do job crafting sobre a dimens?o positiva do bem-estar. Verificou-se a exist?ncia de uma diferen?a significativa entre o efeito do job crafting nas medidas de bem-estar ocupacionais e gerais, indicando um melhor desempenho destas ?ltimas. Por fim, apresenta-se um estudo explorat?rio sobre o modelo de recursos e demandas no trabalho no contexto brasileiro. Valendo-se da t?cnica de an?lise de redes, foram investigadas as rela??es previstas no modelo de recursos e demandas no trabalho, entre as vari?veis de condi??es de trabalho, engajamento no trabalho, job crafting e bem-estar. Os resultados corroboram algumas rela??es previstas no modelo te?rico. Por?m o job crafting, apesar de preditor do engajamento no trabalho, n?o aconteceu em virtude das condi??es de trabalho (recursos e demandas). Este achado indica a necessidade de investigar outros precedentes de natureza intr?nseca do job crafting. Estes cinco produtos da disserta??o avan?am o conhecimento sobre a pesquisa em job crafting no Brasil.

La tesi mira a esaminare la genesi del Calloandro di Giovan Ambrogio Marini nel contesto del ricco e dinamico contesto sociale e culturale della Genova della prima metà del XVII secolo. Le pagine prefattorie premesse alle varie edizioni dell’opera rappresentano un contributo importante per la definizione di un genere la cui diffusione non fu accompagnata, in Italia, da uno studio teorico e sistemico. Dopo una ricognizione delle fonti sulla biografia e la produzione letteraria dell’autore, nel primo capitolo viene proposta una sintesi dettagliata della trama del romanzo che illumina gli elementi fondamentali del testo e del genere. Nel secondo, si prosegue con l’analisi della struttura narrativa dell’opera, soffermando l’attenzione sulle tecniche di costruzione dell’intreccio. Quindi, si procede all’individuazione nel romanzo greco d’epoca ellenistica e nella tradizione comica i modelli letterari che influenzarono in modo più significativo la fantasia del Marini nella composizione del Calloandro. Nel quarto capitolo è affrontato il sistema dei personaggi, in cui, tra le molte figure generiche e inconsistenti, si distinguono alcuni personaggi complessi e imprevedibili: questi fanno del Calloandro un esperimento maturo del genere in cui il realismo psicologico di matrice ligure si combina con il gusto per l’avventura proprio dei romanzi di produzione veneta. / This thesis examines the origin of Giovan Ambrogio Marini’s Calloandro in Genoa’s rich and dynamic social and cultural context of the first half of the XVII century. Introductory pages to the novel’s various editions represent an important contribution about the novel’s developement in Italy, where the success of the genre wasn’t followed by a theoric and systemic study. After a research on the sources concerning the author’s biography and literary production, the first chapter presents a detailed synthesis of the novel’s plot which fixes some fundamental elements of this kind of work. The second chapter is about the novel’s narrative structure focusing on the techniques of the plot’s building. Then the third chapter describes literary models which influenced Marini’s work, in particular the Greek novels of Hellenism and the comic tradition. The fourth chapter analyses the characters' system: there are some subtle and unforeseeable characters, among many generic and insubstantial figures, that make Calloandro a unpredictable novel in which the psychological realism, typical of Ligurian novels, is combined with the taste of adventure, typical of the Venetian novels.
