Cover cropped and tilled table grape vineyard: Data on leaves and stems

Data presented are on mass, length, SPAD and some physiological parameters of leaves and stems in a table grape vineyard of Italia variety grafted onto 1103 Paulsen, covered with a plastic sheet to advance ripening and managed with two soil systems in the Puglia region, South-eastern Italy in 2015 and 2016. The two systems differed for the soil management since in one area of the vineyard a cover crop was used (Trifolium repens L.), whereas in the other area only soil tillage was adopted. The data of the two seasons include: (a) mass of leaves of primary shoot, secondary shoot and opposite the cluster; (b) length of secondary shoots; (c) number of both secondary shoots and leaves of secondary shoots; (d) SPAD values and area of leaves opposite both first and second cluster on the primary shoot; (e) mass of stems of both primary and secondary shoots; and (f) some physiological parameters (Ψstem, temperature, Fv/Fm). The data in this article support and augment information presented in the research article 'Cover crops in the inter-row of a table grape vineyard managed with irrigation sensors: effects on yield, quality and glutamine synthetase activity in leaves' (Sci. Hortic. 281, 2021 https://doi.org/10.1016/j.scienta.2021.109963)

Information balance between newspapers and social networks

[EN] Competing newspapers, tend to publish the same information in a given time frame. However, each editor tends to aggregate and present the news according to certain criteria such as editorial policies, filtering strategies, readers base, etc. Thus, the proper choice and filtering of information makes one newspaper different from the other and, the proper management of such criteria, may deem the success or failure of a newspaper. From the editor’s perspective, the news selection process is a trade-off between informativeness and attractiveness, as determined by the readership. Moreover, is it possible that cultural and political inputs from social media may impact the news selection process? Political news on social networks represent nowadays a valuable informative asset that gives the possibility to correlate newspaper information with public request expressed on social networks. We believe that it is possible to develop a theory to mitigate the newspaper’s cultural identity with the public information needs collected on social media. In our work, we show how to measure the society's request for information through the analysis of public reaction to certain articles on social networks, in particular we present how studying the hashtags and articles shared can be conveyed to understand social dynamics in nowadays discussion.Mazzeo Rinaldi, F.; Russo, A.; Giuffrida, G.

Efeitos do solo e clima numa vinha de uva de mesa com cultura de cobertura. Gestão da rega utilizando redes de sensores

[ENG] TThe use of mulches in vineyards and orchards is a traditional agricultural practice used with the aim of saving moisture, reducing weed growth and improving organic matter content in the soil. In table grape vineyards trained to overhead system in Puglia region (Southeastern Italy), plastic sheets covering the canopy are often used to either advance ripening or delay harvest. In this environment, the living mulches could contribute to the modification of the microclimate around the canopy below the plastic sheets. This condition has an influence on the climatic demand and on both the vegetative and productive activities, mainly in stages with a high evapotranspiration. However, the presence of living mulches could increase the demand of available water and nutrient resources and this could cause a lower yield. The aim of this study was to acquire a suitable knowledge to manage irrigation and verify the influences of living mulches on the vine by using wireless sensor networks to measure the vapor pressure deficit, soil water potential and content.[POR] A utilização de coberturas do solo em vinhas e pomares é uma prática agrícola tradicional, utilizada com o objetivo de preservar a humidade do solo, reduzir o crescimento de infestantes e melhorar o teor de matéria orgânica no solo. Em vinhas de uva de mesa, conduzidas em sistema de pérgula na região de Puglia (sudeste da Itália), são frequentemente usadas coberturas de plástico para promover o avanço da maturação ou o atraso da colheita. Neste ambiente a utilização de enrelvamentos pode contribuir para a modificação do microclima do copado. Esta condição pode influenciar a demanda atmosférica, bem como a atividade vegetativa e reprodutiva da videira, principalmente em períodos de elevada evapotranspiração. No entanto, a presença do enrelvamento pode originar um aumento da demanda dos recursos disponíveis, nomeadamente água e nutrientes, o que poderá provocar uma quebra de produção. O objetivo deste estudo foi adquirir conhecimento para a gestão da rega e, simultaneamente, verificar a influência dos enrelvamentos na atividade da videira, usando para o efeito redes de sensores “sem fio” para medir o déficit de pressão de vapor, o potencial e o conteúdo de água no solo.The development of this work was supported by: The Spanish Ministry of Science and Innovation through the project RIDEFRUT (ref.

Investigating Fake and Reliable News Sources Using Complex Networks Analysis

The rise of disinformation in the last years has shed light on the presence of bad actors that produce and spread misleading content every day. Therefore, looking at the characteristics of these actors has become crucial for gaining better knowledge of the phenomenon of disinformation to fight it. This study seeks to understand how these actors, meant here as unreliable news websites, differ from reliable ones. With this aim, we investigated some well-known fake and reliable news sources and their relationships, using a network growth model based on the overlap of their audience. Then, we peered into the news sites' sub-networks and their structure, finding that unreliable news sources' sub-networks are overall disassortative and have a low–medium clustering coefficient, indicative of a higher fragmentation. The k-core decomposition allowed us to find the coreness value for each node in the network, identifying the most connectedness site communities and revealing the structural organization of the network, where the unreliable websites tend to populate the inner shells. By analyzing WHOIS information, it also emerged that unreliable websites generally have a newer registration date and shorter-term registrations compared to reliable websites. The results on the political leaning of the news sources show extremist news sources of any political leaning are generally mostly responsible for producing and spreading disinformation

Effetti di diverse tipologie di inerbimento sugli aspetti qualitativi della cultivar Italia in provincia di Bari

Il sud Italia, in modo particolare Puglia e Sicilia , rappresenta il principale areale di coltivazione dell'uva da tavola con oltre il 90 % della produzione nazionale. AI fine di ottenere una gestione sempre più sostenibile sia dal punto di vista ambientale sia economico e nello stesso tempo ottenere produzioni di qualità, negli ultimi anni sono state avviate delle sperimentazioni per una gestione del terreno eco-compatibile con pratiche quali inerbimento, pacciamatura, ecc . Da anni sono disponibili risultati di sperimentazioni e applicazioni su vite da vino specialmente in ambienti settentrionali; invece molto limitate e quasi scarse sono le infoomazioni per la viticoltura da tavola. Attualmente si sta diffondendo, anche negli ambienti del meridione d'Italia, la tecnica dell'inerbimento sia naturale sia artificiale per diverse specie arboree da frutto. Sulla base di queste considerazioni si è pensato di impostare una prova di inerbimento in un vigneto di vite ad uva da tavola in Puglia. La prova è iniziata nell'annata 2009/2010 in un vigneto commerciale di cinque anni condotto in irriguo e sito in agro di Acquaviva delle Fonti (BA). La cultivar utilizzata nella prova è Italia, innestata su 1103P, e la fooma di allevamento il tendone. Le tesi messe a confronto sono state: TI, inerbimento con trifoglio sotterraneo (Trifolium subterraneum L.); T2, inerbimento con festuca (Festuca arundinacea Schreb.); TI , inerbimento naturale; T4 , controllo lavorato. I risultati del primo anno della sperimentazione, tuttora in corso, mostrano che non sono emerse differenze significative tra le tesi a confronto per le caratteristiche biometriche della bacca e per la produzione di uva/ceppo, quest'ultima variata tra i 23,03 kg del controllo lavorato ed i 25,76 kg dell'inerbimento naturale. La colorazione della buccia della bacca ha presentato invece delle differenze statisticamente significative: il valore della luminosità (L*) nelle tesi inerbite con trifoglio (41,59) e festuca (41 ,03) è stato superiore rispetto all'inerbimento naturale (39,63) ed al controllo lavorato (40,41). La saturazione (C*) è risultata significativamente più bassa nel controllo lavorato rispetto alle tesi inerbite , mentre la tinta (h°) non ha mostrato differenze tra le tesi. L'inerbimento non ha influito, in generale, sulla consistenza della bacca ed anche per gli altri parametri chimici (°Brix, pH, acidità titolabile) non sono state rilevate differenze degne di rilievo tra i dati ottenuti per le diverse tesi
