Le innovazioni sociali delle attività agricole. Esempi di buone pratiche in Puglia
Full text linkL’agricoltura è chiamata a svolgere una funzione più ampia di quella produttiva tradizionale, a cui accosta altre funzioni, quali quelle ambientali, paesaggistiche, culturali, ivi compresa l’erogazione di servizi sociali e di benessere (come benefici multipli forniti dagli ecosistemi) per la collettività, che mirano anche a contrastare il declino, lo spopolamento e la trasformazione delle aree rurali. La legge 141 del 18 agosto 2015 promuove l’agricoltura sociale, puntando all’integrazione tra pratiche agricole e servizi sociali attraverso la diversificazione delle attività rurali. Lo scopo del contributo è esplorare e catalogare le funzioni esercitate dalle imprese che svolgono attività di agricoltura sociale ed il livello di innovazione in termini di servizi alla collettività. Tali attività sociali rappresentano forme di innovazione con ricadute, in particolare, all’interno dei sistemi rurali. Gli indicatori di analisi documentale scaturiscono dalla letteratura nazionale e straniera e si guarda ad esempi di modelli virtuosi con riferimento alla regione Puglia, come esempi di buone pratiche per illustrare empiricamente la tipologia di innovazione sociale agricola adottata
Memoria, narrazioni e mappe di comunità: l’esperienza dell’Ecomuseo nel Mar Piccolo di Taranto

The rediscovery of characteristic rural landscapes. An opportunity to create new activities?
Full text linkFor some years now, researchers in many geographical and other disciplinary fields have believed that historical rural landscapes contain an educational value for the landscapes of the future, in terms of analysis as well as protection in general and geo-economic aspects in particular, as an identity expression of the territory and as a preponderant element for the recovery of the same. In fact, in landscape studies the idea is widespread that historical and characteristic rural landscapes are not only the elements of a cultural heritage capable of preserving the memory of the past but also the bearers of a rational perspective for the future of European agriculture. The COVID-19 pandemic caused social and economic changes; critical issues highlight the need for a more integrated approach, taking into account the rediscovery of rural landscapes to practice open-air activities. Through a review of the international literature and the analysis of case studies, the paper aims to highlight the renewal processes of some cultural practices abandoned over the years but which today are an integral part of the local economy. In particular, the paper analyses the cases of two characteristic citrus groves in Apulia and Sicily, in the south of Italy. They demonstrate how the renewal of ancient practices such as the cultivation of citrus fruits together with the value of landscapes can represent an opportunity for an economic development of territories.Depuis quelques années, de nombreuses études géographiques et dans d’autres champs disciplinaires considèrent que les paysages ruraux historiques contiennent une valeur éducative pour les paysages du futur, tant en termes d’analyse que de protection en général et d’aspects géo-économiques en particulier, en tant qu’expression de l'identité du territoire et comme élément prépondérant pour la récupération de celui-ci. En effet, l’idée est répandue dans les études paysagères que les paysages ruraux historiques ne sont pas seulement des éléments d’un patrimoine culturel capables de conserver la mémoire du passé, mais aussi porteurs d’une perspective rationnelle d’avenir pour l’agriculture européenne. Grâce à une revue de la littérature internationale et à l’analyse d’études de cas, l’article vise à mettre en évidence les processus de renouvellement de certaines pratiques culturelles abandonnées au fil des ans et qui, aujourd’hui, font pourtant partie intégrante de l’économie locale. En particulier, l’article observera les cas d’anciennes plantations d’agrumes. Les deux paysages historiques analysés, en Pouilles et en Sicile, montrent comment le renouveau de pratiques anciennes comme la culture des agrumes peut représenter une opportunité de développement pour les territoires méditerranéens
Inter- and intra-specific competition between Paracentrotus lividus and Arbacia lixula in resource-limited barren areas
No full textThe sea urchins Paracentrotus lividus and Arbacia lixula coexist in the infralittoral zone along the
Mediterranean and north-east Atlantic coasts. Through their grazing activity they can produce and maintain
barren grounds, habitat characterised by low algal diversity and productivity. This study addresses the
coexistence of these species within severely limited barren grounds by assessing differences in population
structure, feeding preferences and conditions. Density, size structure, feeding conditions and gut contents of
the two species, along with the associated algal assemblage were analysed in a hierarchical sampling design
(Locations: thousands of meters apart; Sites: hundreds of meters apart). The algal assemblage, dominated by
encrusting corallines (EC), was depauperate with bare rocks representing around 67% of the total percent
cover, and homogeneous both at the Site and at the Location level. Sea urchins showed significant variability
in density and gut conditions only at the Site level. No compensative mechanisms have been observed
(no inverse correlation between the two species). The gut contents of the two species were quite different:
A. lixula fed mainly on encrusting corallines, while P. lividus fed on non-encrusting macrophytes. Food
limitation was detected for P. lividus, as a consequence of intra-specific competition. Our results highlight
that in barren conditions a large trophic niche differentiation occurs, demonstrating that the two urchins
play complementary and synergic roles in the maintenance of barrens in the Mediterranean
Revitalizing tourism through citrus routes. Exploring new practices and challenges
No full textCitrus fruits have always played a vital role in the Mediterranean diet, and their cultivation has
been a significant part of the region’s heritage. In recent years, the tourism industry has recognized the potential of citrus farms as attractive destinations for tourists. With their beautiful flowering, colorful leaves, and fruit picking activities, citrus farms have become popular tourist attractions. This trend has prompted a shift towards multipurpose agriculture, with citrus farms serving not only as places of production but also as tourism hotspots. The rural heritage of citrus fruits has become a valuable asset for the development of new tourism paths. This
study focuses on two case studies in Southern Italy, in Apulia and Sicily, investigating the characteristics of integrated relational tourism in territories with a citrus production focus. The methodological approach is focused on exploratory qualitative analysis, collecting data from local citrus producers to understand their experiences and perceptions of citrus tourism. The exceptional quality and genuineness of Apulian and Sicilian citrus fruits are essential for promoting a healthy lifestyle and enriching the tourist offer. The study highlights the renewal of
cultural practices that were once abandoned but have now become an integral part of the local economy. However, to sustain this growth, citrus tourism must integrate personalized, creative, unique, and innovative experiences to attract more tourists
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
An investigation on the effect of Li+/Ni2+ cation mixing on electrochemical performances and analysis of the electron conductivity properties of LiCo0.33Mn0.33Ni0.33O2
No full textTwo alternative synthesis procedures, i.e. co-precipitation and sol gel, have been used to prepare LiCo0.33Mn0.33Ni0.33O2 samples. Inductive coupled plasma optical emission spectroscopy (ICP-OES), X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) have been used in order to determine the stoichiometry, the structural characteristic and the morphology of the materials. The results show that these samples obtained by sol gel have a high level of crystal defectivity, particularly in terms of Ni2+/Li+ cation mixing. We show that the defectivity reflects directly on electrochemical performances since lithium diffusion is hindered by nickel cations in the 3a sites as well as by a distorted structure. Then, co-precipitation samples have been selected as the most promising for battery application. The results confirm that this sample may be effectively used as cathode in advanced lithium ion polymer batteries formed by a Li4Ti5O12 anode and a PVdF LiPF6 EC:PC gel polymer electrolyte
