Molecular Imprinted Polymers Coupled to Photonic Structures in Biosensors: The State of Art
No full textOptical sensing, taking advantage of the variety of available optical structures, is a rapidly expanding area. Over recent years, whispering gallery mode resonators, photonic crystals, optical waveguides, optical fibers and surface plasmon resonance have been exploited to devise different optical sensing configurations. In the present review, we report on the state of the art of optical sensing devices based on the aforementioned optical structures and on synthetic receptors prepared by means of the molecular imprinting technology. Molecularly imprinted polymers (MIPs) are polymeric receptors, cheap and robust, with high affinity and selectivity, prepared by a template assisted synthesis. The state of the art of the MIP functionalized optical structures is critically discussed, highlighting the key progresses that enabled the achievement of improved sensing performances, the merits and the limits both in MIP synthetic strategies and in MIP coupling

Precision agriculture by proximal and remote sensing: from the 3D modelling and tree metrics computation to the analysis of rural landscape
No full textL'agricoltura di precisione (AP) rappresenta un nuovo modo di impiegare la tecnologia digitale per rendere l'agricoltura più efficiente e produttiva utilizzando dati accurati. Le principali soluzioni tecnologiche di PA oggi disponibili appartengono ai campi del telerilevamento e del rilevamento prossimale. Tra queste, l'uso dei sistemi Lidar (light detection and ranging) e di visione stereoscopica sono utilizzati per la modellazione tridimensionale degli elementi vegetali (modelli 3D, point clouds, mesh, etc.). In merito a quest'ultimo aspetto la maggior parte degli studi è in ambito forestale, mentre l'utilizzo dei sistemi modellazione 3D presenta ampi spazi di studio e applicazione nel settore delle colture permanenti. Come vedremo in successivamente, il lavoro di dottorato si è concentrato su sistemi agricoli per la coltivazione dell'olivo. In particolare perché concentrarsi sul settore olivicolo ci permette di testare le potenzialità della PA in un settore cruciale non solo dal punto di vista produttivo delle culture permanenti, ma anche ecologico e paesaggistico. Questo approccio del lavoro ci permette di avere impatto in un promettente campo di innovazione tecnologica. Pertanto, il progetto di dottorato si concentra su tre linee di ricerca principali. La prima linea di ricerca mira a dimostrare l'elevata accuratezza dei dati metrici estratti da test su singoli alberi mediante ricostruzione del modello a partire da nuvole di punti campionati attraverso un dispositivo Mobile Laser Scanner Lidar (MLS). La seconda linea di ricerca si concentra sul rilevamento con Laser Scanner Mobile delle strutture arboree in oliveti specializzati. Applicando diversi algoritmi di classificazione degli alberi e di mashing delle chiome per derivare il volume di singole chiome con elevata precisione. L'analisi è condotta confrontando i volumi ottenuti dal rilievo MLS con due verità a terra o primitive (forme toroidali e paraboloidi).
La terza e linea di ricerca si è concentrata sull'analisi del paesaggio all'interno in un caso di studio in centro Italia (DOP Cartoceto). L'analisi del paesaggio è condotta adottando diversi approcci di analisi diacronica dei cambiamenti di uso del suolo e metriche del paesaggio. Per l'analisi è stato necessario costruire un robusto dataset multi temporale (ortofoto aeree, carte storiche, etc.). In particolare è stato possibile ricostruire lo stato di uso del suolo per cinque periodi nell'arco di oltre 70 anni, in ambiente GIS, individuando le diverse tipologie di modelli colturali di oliveto all'interno del territorio indagato. Successivamente è stato possibile misurare un pool di metriche del paesaggio (diversità, entropia, forma, frequenza, etc.) per analizzare le trasformazioni del paesaggio fornendo una chiara visione delle dinamiche di cambiamento avvenute in quelle aree. I risultati complessivi conseguiti nello sviluppo di queste tre linee di ricerca appaiono molto soddisfacenti. Essi rappresentano quindi un significativo stimolo sia per i singoli olivicoltori sia per le strutture associative che gestiscono il comparto olivicolo locale, in particolare il consorzio di produzione dell’olio extravergine di oliva di Cartoceto DOP, per introdurre pratiche innovative fondate sull’utilizzo di tecnologie digitali avanzate all’interno di questo importante comparto agricolo.Precision agriculture PA is a new concept adopted worldwide. Precision farming methods use large amounts of data and information to improve agricultural resource use and crop quality. In essence, PA is the science of improving agriculture sustainability by assisting farmers' decisions using high-tech sensors and analytical tools. The main PA technology solutions available today belong to remote and proximal sensing fields. Among them, Lidar (light detection and ranging) and stereoscopic vision systems are used for the three-dimensional modelling of plant elements (3D models, point clouds, meshes, etc.). Regarding the latter, most studies are in forestry, while the use of 3D modelling systems has a broad scope for study and application in permanent crops. As we will see in the following paragraphs, the doctoral work focused on agricultural systems for olive cultivation. Above all because focusing on the olive sector has a twofold significance. On the one hand, it allows us to test the potential of PA in a crucial sector from the production point of view of permanent crops. On the other, to test the seminal contribution of PA from the ecological and landscape point of view. This approach of the work allows us to seek to have an impact in the promising field of farming technological innovation. Therefore, the PhD project focuses on three main lines of research. The first line of research aims to demonstrate the high accuracy of metric data extracted from single tree tests by model reconstruction starting from point clouds sampled through a Mobile Laser Scanner Lidar (MLS) device. The second line of research focuses on the Mobile Laser Scanner survey of tree structures in specialised olive groves by applying different tree classification and canopy mashing algorithms to derive the volume of individual canopies with high accuracy. The analysis is conducted by comparing the volumes obtained from the MLS survey with two ground truths or primitives (toroidal and paraboloid shapes). The third line of research focused on landscape analysis inside a case study in central Italy (PDO Cartoceto). The landscape analysis is conducted by adopting different approaches of diachronic analysis of land use changes and landscape metrics. The analysis uses a robust multi-temporal dataset (orthophoto maps, historical maps, aerial images, etc.) to reconstruct the land use for five periods over more than 70 years in a GIS environment. The dataset allowed for identifying the different types of olive grove cropping patterns within the investigated area. Further, the landscape transformations have been analysed by measuring a pool of landscape metrics (diversity, entropy, shape, frequency, etc.) to provide a clear view of the dynamics of change that occurred in those areas. The overall results achieved in the development of these three lines of research appear very satisfactory. They, therefore, represent a significant stimulus for both individual olive growers and the associative structures that manage the local olive sector, particularly the Cartoceto DOP extra virgin olive oil production consortium, to introduce innovative practices based on the use of advanced digital technologies in the agricultural sector

The Lettere of Andrea Calmo: authorial artifices and historical reality
No full textopenNonostante l’edizione di Vittorio Rossi del 1888, la raccolta di "ingegnosi cheribizzi" e di "fantastiche fantasie" di Andrea Calmo è ancora avvolta da un certo mistero. L’autore, dissimulando la propria identità dietro alla “maschera” dell’umile pescatore veneziano, è stato in grado di offrire uno spaccato della cultura e della società nella Venezia cinquecentesca.
In particolare, è il quarto libro delle Lettere ad aver suscitato maggiore interesse tra gli studiosi ed i lettori: pubblicato nel 1566, a diversi anni di distanza dai primi tre, questo libro si distingue per il fatto che tutte le epistole sono indirizzate a delle donne immaginarie o realmente esistite.
In questa sede si propone, in primo luogo, uno studio della biografia del Calmo accompagnata da un’analisi del contesto storico-culturale della Venezia cinquecentesca; in secondo luogo, invece, viene proposto un commento di alcune lettere dell’ultimo libro dell’opera calmiana, che cerchi di far luce principalmente sull’aspetto linguistico e contenutistico del testo.Despite Vittorio Rossi's 1888 edition, Andrea Calmo's collection of "ingegnosi cheribizzi" and "fantastiche fantasie" is still shrouded in a certain mystery. The author, dissimulating his own identity behind the "mask" of the humble Venetian fisherman, was able to offer a cross-section of culture and society in sixteenth-century Venice.
In particular, it is the fourth book of the Letters that has aroused greater interest among scholars and readers: published in 1566, several years after the first three, this book stands out for the fact that all the epistles are addressed to women imaginary or actually existed.
Here we propose, first of all, a study of Calmo's biography accompanied by an analysis of the historical-cultural context of sixteenth-century Venice; secondly, however, a commentary on some letters from the last book of Calmo's work is proposed, which seeks to shed light mainly on the linguistic and content aspect of the text
Trusted Tales: Creating Authenticity in Literary Representations from Ex-Yugoslavia
No full textThis research deals with questions of authority and authenticity and how they are expressed, constructed, and appropriated within the Anglophone book market. It considers the body of literature written about ex-Yugoslavia since the 1990s Balkan conflicts by exiled writers from the region which has entered the international literary canon. Books’ routes from original publishers into English translation are discussed through practices of trust, one of the crucial social devices underpinning their exchange. Within these cross-cultural processes, the role of cultural brokers is crucial. Symbolic and cultural resources are specifically mobilised through their powerful author brands.
By exploring authenticity in the context of book publishing, I further look at how ideas and practices of community are employed and negotiated by writers and those who promote their books. My field is multi-sited and fluid, reflecting how different individual and national positions are enacted and performed through strategies ranging from unconscious dispositions to deliberate intentions. This research thus brings together ideas of the author as an authentic, representative voice together with exile as a position that grants them a new lease of relevancy in the post-socialist context.
Although ex-Yugoslav books occupy a ‘high end’ niche of the UK market, constrained by commercial as well as political, cultural, and institutional forces, in public discourse ideas of the ‘free market’ and ‘free speech’ are mobilised to produce various types of modernisation narratives. The (post)socialist production of literature is perceived as having to ‘evolve’ into a capitalist model: this would allow not only healthy competition and consumer choice but guarantee an individual writer ‘free speech’ as a basic human right. Therefore, the most general question this research raises is what kind of foreign literature gets translated into English, under what socio-cultural conditions and which politics of representation it serves within the project of world literature
Intellectual Capital Disclosure: Some Evidence from Healthy and Distressed Banks in Italy
No full textThe article investigates the intellectual capital disclosure of Italian banks over the years 2016–2017, applying the specific lens of healthy and distressed banks. To this end, we used content analysis and encoding techniques. The main results point out that intellectual capital (IC) disclosure is generally poor and that the intensity of disclosure varies slightly between healthy and distressed
banks. Regarding the quality of disclosure, healthy banks present a higher, albeit modest, tendency to disclose non-qualitative and forward-looking information, maybe due to the fact that they are more focused on the strategies and the relationships with stakeholders as opposed to a more short-term approach of the distressed banks. To complement our study on healthy and distressed banks, we repeated the analysis focusing on bank size and independent directors. In this case, results do not show relevant differences in terms of IC disclosure. Hence, our findings suggest the need to consider banks’ IC disclosure as a strategic asset for increasing, among others, transparency and reputation
