The political irruption of short video: Is TikTok a new window for Spanish parties?
2022
This paper analyses the use of TikTok by the main Spanish parties. The article studies the intensity of use of the short video social network by the accounts of the Partido Popular, Vox, Podemos and Ciudadanos, their narratives and themes, and the views obtained based on them. The research applies a content analysis to the videos published by these groups from account creation until the end of 2020, a period in which the PSOE had no presence. The corpus amounts to 182 units of analysis. The results show that the partisan use of TikTok is still in its infancy and that its intensive use is limited to newly emerging parties, with more favourable results for the most polarised groupings.

Total petroleum hydrocarbons (TPH) determination in surfactant stabilized marine water emulsions
2022
Bilge waters are wastewaters produced on boats during navigation and usually contain hydrocarbons and oils. They cannot be released into the sea if not below certain hydrocarbon concentration limits set by current legislation. Surfactants are often used to improve the solubility of petroleum hydrocarbons in water and in this work, the analytical approach proposed is suitable to determine accurately the concentration of hydrocarbons in surfactant-rich waters, as found in bilge water or similar wastewater. The method relies on the surfactant precipitation by addition of potassium and calcium salts, which also promote TPH extraction through a “salting out” effect. This allows for an accurate d…
Speeding up new product development through entrepreneurial orientation in SMEs: The moderating role of ambidexterity
2022
International audience; This paper analyzes the influence of small and medium-sized enterprises' (SMEs) entrepreneurial orientation (EO) on its capacity to quickly introduce new products to the market (namely, speed to market). Specifically, we suggest that firms will exhibit greater speed to market when displaying either low or high levels of EO. We also suggest that the EO – speed to market relationship will be contingent on firms' ambidexterity, or its capacity to simultaneously embrace exploratory and exploitative strategies. To test our hypotheses, we collected survey data from 384 SMEs belonging to four sectors in Spain: biotechnology, ceramic tiles, toys and footwear. Our findings co…
Frammenti di biografie plurali
2022
Ritorno a Palermo dopo tredici anni trascorsi in Umbria. Anni importanti in cui ho frequentato l’università laureandomi in filosofia e conseguendo un dottorato di ricerca; indagando sui temi del disagio psichico e della crisi della presenza in De Martino; sotto la guida di Tullio Seppilli, che di De Martino era stato allievo e il cui rigore nella ricerca è stato per me un esempio indimenticabile. Scappata a diciotto anni da una terra che mi aveva schiacciata con la sua violenza. In primo luogo sul versante privato. Una gelida brutalità di cui – quando sono andata via, determinata a non tornare – non percepivo fino in fondo i risvolti sul piano politico e della limitazione degli spazi fisici…
Taranto città arcipelago. Un caso di emergenza abitativa
2022
Lo scritto restituisce in chiave critica gli esiti della sperimentazione progettuale, sviluppata in occasione del seminario itinerante di progettazione architettonica Villard, sul tema della rigenerazione dei quartieri di Edilizia Residenziale Pubblica a Taranto. Una città fortemente segnata dalla sensibile questione legata alle oltre millecinquecento richieste di accesso da parte dei cittadini aventi diritto ad una casa. Una condizione che determina un forte disagio sociale nelle famiglie meno abbienti escluse dall’assegnazione di alloggi per la limitata offerta di abitazioni pubbliche. Le aree oggetto di studio del Seminario coincidono con tre distinte parti della città di Taranto: Tambur…

Il risveglio dal sogno
2022
«La storia è l’incubo da cui mi voglio svegliare». Queste parole sono pronunciate da Stephen Dedalus, nelle primissime pagine del capolavoro di James Joyce, l’Ulisse. Ci troviamo all’inizio del romanzo quando Dedalus introduce una delle classiche domande che assillano il pensiero filosofico, religioso, letterario e artistico contemporaneo: la storia ha ancora un senso?
Adjunctive Brivaracetam in Older Patients with Focal Seizures: Evidence from the BRIVAracetam add‑on First Italian netwoRk Study (BRIVAFIRST).
2022
BACKGROUND: The management of epilepsy in older adults has become part of daily practice because of an aging population. Older patients with epilepsy represent a distinct and more vulnerable clinical group as compared with younger patients, and they are generally under-represented in randomized placebo-controlled trials. Real-world studies can therefore be a useful complement to characterize the drug's profile. Brivaracetam is a rationally developed compound characterized by high-affinity binding to synaptic vesicle protein 2A and approved as adjunctive therapy for focal seizures in adults with epilepsy. OBJECTIVE: The aim of this study was to assess the 12-month effectiveness and tolerabil…

Life satisfaction and tax morale: The role of trust in government and cultural orientation
2022
Taxes are essential for a government to function correctly, because they fund public services and promote long-term growth in a country. Tax morale is a positive attitude toward taxation shaped by extrinsic and intrinsic motivations, including numerous psychological factors. However, these factors are far from completely clear and a better understanding of what drives tax morale can greatly help governments in the design of tax policies and their administration. In this paper we test the novel hypothesis that life satisfaction is one of the psychological aspects affecting tax morale. Using longitudinal data from the World Value Survey, we show that people more satisfied with their own life …
Il mese di produzione influenza la qualità di formaggi tipici?
2022
Il settore lattiero-caseario mediterraneo rappresenta una delle più importanti attività legate al lavoro delle terre montane e marginali e alla produzione di prodotti tipici e di qualità. Un prodotto “tipico” è il risultato di diversi fattori strettamente legati all’origine geografica e alle tradizioni sociali e culturali dell’area di produzione. Tali prodotti sono da sempre uno strumento per valorizzare la biodiversità, la cultura e l’economia di definite aree mediterranee. L’Unione Europea riconosce ufficialmente questa diversificazione di prodotto attraverso l’attribuzione di marchi di qualità a denominazione di origine protetta (DOP) e a indicazione geografica protetta (IGP). Nella poli…
Posterior epidural intervertebral disc migration and sequestration: A systematic review
2022
Posterior epidural intervertebral disc migration and sequestration (PEIMS) is a rare and debilitating complication of degenerative disc disease. Radiological differential diagnosis is often challenging, complicating the accurate planning of appropriate treatment strategies. We systematically reviewed the literature on PEIMS, focusing on clinical-radiological features and available treatments. PubMed, Scopus, Web of Science, and Cochrane were searched to include studies reporting clinical data of patients with PEIMS. Clinical characteristics, treatment strategies, and functional outcomes were analyzed. We included 82 studies comprising 157 patients. Median age was 54 years (range, 19-91). PE…

The Redesigned Serpens, a Low-Cost, Highly Compliant Snake Robot†
2022
The term perception-driven obstacle-aided locomotion (POAL) was proposed to describe locomotion in which a snake robot leverages a sensory-perceptual system to exploit the surrounding operational environment and to identify walls, obstacles, or other structures as a means of propulsion. To attain POAL from a control standpoint, the accurate identification of push-points and reliable determination of feasible contact reaction forces are required. This is difficult to achieve with rigidly actuated robots because of the lack of compliance. As a possible solution to this challenge, our research group recently presented Serpens, a low-cost, open-source, and highly compliant multi-purpose modular…
Gli ebrei in Italia, il dibattito su Israele e la questione ebraica. Quattro riflessioni recenti
2022
La storia degli ebrei nell'Italia contemporanea è stata molto discussa dalla recente storiografia. In questa nota si prendono in esame quattro libri pubblicati tra il 2018 e il 2020 che affrontano il tema da prospettive differenti come il ruolo politico degli ebrei nell'Italia liberale e negli anni della grande guerra, la storia delle persecuzioni in età fascista, il problematico avvento della Repubblica, la raffigurazione degli ebrei e di Israele nelle sinistre italiane e la più generale percezione di Israele nel mondo politico e culturale italiano.

2022
In the present study, the chemical composition of the essential oil from aerial parts of Parentucellia latifolia (L.) Caruel collected in Central Sicily was analyzed by gas chromatography and gas chromatography–mass spectrometry. The results showed the presence of sesquiterpene hydrocarbons, with germacrene D and germacrene B accounting, respectively, for 59.2% and 24.3% of the total oil. Different colonies of bacteria and fungi frequently affect cellulosic objects such as books stored in libraries and museums. The antibacterial and antifungal activity against some microorganisms infesting historical-artistic craftsmanship was determined, demonstrating that the essential oil was particular…

Probabilistic solution of a homogeneous linear second-order differential equation with randomized complex coefficients
2022
In this paper, an exact expression for the first probability density function of the solution stochastic process to a randomized homogeneous linear second-order complex differential equation is determined. To complete the probabilistic analysis, the first probability density functions of the real and complex contributions of the solution stochastic process are also calculated. To compute the densities, the random variable transformation method is applied under general hypothesis, all coefficients and initial conditions are absolutely continuous complex random variables. The capability of the theoretical results established is demonstrated by several numerical examples. Finally, we show the …

2022
Abstract This study was dedicated to apply biological treatment using Lactobacillus (LAB) fermentation separately or in combination with an acoustic screening method for the prevention of mycotoxins in Fusarium spp. contaminated wheat-based products. Wheat samples of different contamination were treated separately using antimicrobial LAB strains (L. casei, L. plantarum, L. paracasei, and L. uvarum) and the changes on the level of deoxynivalenol (DON) and its conjugates such as 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), and DON-3-β-D-glucoside (D3G)) were evaluated using UHPLC-QqQ-MS/MS and UHPLC-Orbitrap-HRMS. Additionally, an acoustic device was used to analyse DON…
Metal stresses modify soluble proteomes and toxin profiles in two Mediterranean strains of the distributed dinoflagellate Alexandrium pacificum
2022
WOS:000789651000009; HABs involving Alexandrium pacificum have been reported in metal-contaminated ecosystems, suggesting that this distributed species adapts to and/or can tolerate the effects of metals. Modifications in soluble proteomes and PST contents were characterized in two Mediterranean A. pacificum strains exposed to mono- or polymetallic stresses (zinc, lead, copper, cadmium). These strains were isolated from two anthropized locations: Santa Giusta Lagoon (Italy, SG C10-3) and the Tarragona seaport (Spain, TAR C5-4F). In both strains, metals primarily downregulated key photosynthesis proteins. Metals also upregulated other proteins involved in photosynthesis (PCP in both strains)…
Baveno VII – Renewing consensus in portal hypertension
2022
To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD – defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled “Personalized Care for Portal Hypertension”. The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the …

Investigation of archaeological amphorae from the Egadi battles
2022
Abstract Archaeological ceramics are considered one of the most important sources of both technological and chronological information. Here, the investigation of some archaeological underwater amphorae from the Egadi’s Battle, that decided the end of the First Punic War (241 B.C.), is reported. X-ray Diffraction (XRD), X-ray Fluorescence (XRF), petrography, and Thermoluminescence (TL) were used to determine the composition of the amphorae and to evaluate the compatibly of their age with the above Battle. Considering the historical importance of the act and the well-defined historical collocation these amphorae represent an interesting archaeometric case study.
Finitary unification in locally tabular modal logics characterized
2022
We provide necessary and sufficient conditions for finitary unification in locally tabular modal logics, solely in terms of Kripke models. We apply the conditions to establish the unification types of logics determined by simple finite frames. In particular, we show that unification is finitary (or unitary) in the logic determined by the fork (frame F4, see Fig. 6), the rhombus (frame F5), inGL.3m,GrzBd2,S4Bd2and other logics; whereas it is nullary in the logic of F6, and of the pentagon FN5. In Appendix analogous results are given for superintuitionistic logics.
Catalan Sociolinguistics
2022
Humans learned to talk a thousand years ago, but our written abilities are more modern. Technological progress—from writing to digitalization—have crucially changed the way we communicate with each other. Yet, research about linguistic uses, which happens under the area of sociolinguistics, is only a modern phenomenon. In fact, the concept sociolinguistics was only coined in 1949. In the Catalan culture, the first sociolinguistic studies took the form of anti-Franco essays. It was only during the late 1960s that these essays took a sociological dimension thanks to Lluís-Vicent Aracil and Rafael-Lluís Ninyoles. Nowadays, in a context of increasing multidisciplinary approaches, Catalan sociol…
Food sustainability perception at universities: Education and demographic features effects
2022
The 2030 Agenda of the United Nations merged in 17 goals the strong need to change the pattern of human life on the planet in a path of strengthening sustainability especially in an era that is widely defined as Anthropocene. The Global Action Program (GAP) on Education and Sustainable Development was adopted based on the power of education and knowledge with the idea of 'green universities' aimed at improving the perception of sustainability for future policy decisions. Based on a Best-Worst (BW) scaling methodological approach, in this study we quantified the preferences of generation Y at University of Turin as they relate to issues explicitly connected to the ordinary consumption of foo…
