District metered area design through multicriteria and multiobjective optimization
2022
[EN] The design of district metered areas (DMA) in potable water supply systems is of paramount importance for water utilities to properly manage their systems. Concomitant to their main objective, namely, to deliver quality water to consumers, the benefits include leakage reduction and prompt reaction in cases of natural or malicious contamination events. Given the structure of a water distribution network (WDN), graph theory is the basis for DMA design, and clustering algorithms can be applied to perform the partitioning. However, such sectorization entails a number of network modifications (installing cut-off valves and metering and control devices) involving costs and operation changes,…
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.
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…

Optimal standalone data center renewable power supply using an offline optimization approach
2022
Abstract Because of the increasing energy consumption of data centers and their C O 2 emissions, the ANR DATAZERO2 project aims to design autonomous data centers running solely on local renewable energy coupled with storage devices to overcome the intermittency issue. In order to optimize the use of renewable energy and storage devices, a MILP solver is usually in charge of assigning the power to be supplied to the data center. However, in order to reduce the computation time and make the approach scalable, it would be more appropriate to use a polynomial time algorithm. This paper aims at showing and proving that it is possible to provide an optimal power profile via a deterministic algori…
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…
Portable Spectroscopic Techniques for the Non-invasive Identification of two historical yellow pigments: Applications and Practical Challenges
2022
Abstract Decades of technological advances in instrumental analysis have transformed many techniques from laboratory in portable analytical tools with increasing their applicability in situ to the study of cultural heritage. It is known that the painting realisation varies from artist to artist, and the identification of the pigments provides a decisive contribution to trace their authenticity and to support an appropriate restoration work. However, in some cases, due to the complexity of painting composition, it is difficult to distinguish between pigments having a similar chemical composition and colour. Here, a systematic study through combined use of portable non-invasive spectroscopic …
Triggering Open Innovation Processes Through Organizational Emotional Capability and Rival's Absorptive Capacity Orientation
2022
In this article, we analyze the direct effects of the open innovation (OI) processes of acquisition and exploitation on innovation performance (IP), as well as the effects of two antecedents of OI: organizational emotional capability (EC) and rivaĺs absorptive capacity orientation (RACO). RACO implies processing external information in an analytical manner, whereas an intuitive approach is implicit in EC. The research model is tested in a sample of medium-low-technology Colombian small and medium-sized enterprises (SMEs) using structural equations by the consistent partial least squares method. Our results provide evidence on a significant effect of the OI acquisition process on IP, as well…
I diritti degli animali
2022
Il contributo affronta il tema dei diritti degli animali nell'ambito delle opere di Paolo Cendon, analizzandolo nel quadro delle fragilità esistenziali. Per danno da perdita dell’animale di affezione si intende, infatti, il danno non patrimoniale, di tipo esistenziale, derivante al proprietario dalla perdita o dal ferimento dell’animale di affezione, capace di caratterizzare e, talvolta, dominare, del tutto, la rete affettiva familiare. Non si tratta, cioè, di risarcire la lesione di un diritto alla vita dell’animale, bensì di compensare la lesione del diritto alla relazione affettiva intrattenuta con l’animale, nell’ambito della quale l’individuo può esplicare la propria personalità relazi…
Single crystal X-ray structural dataset of 1,2,4-dithiazolium tetrafluoroborate
2022
Herein, we present the crystallographic dataset of 1,2,4-dithiazolium tetrafluoroborate. Single crystal X-ray structural analysis evidences that the 1,2,4-dithiazolium ring is almost planar. The 1,2,4-dithiazolium and tetrafluoroborate ions contribute in hydrogen bonding wherein the N-H·N hydrogen bonding in 1,2,4-dithiazolium dimer forms an eight-membered pseudo ring with the R22(8) Etter's graph set. The information provided in this data contributes to the understanding of structural chemistry and hydrogen bonding interactions in dithiazole derivatives.

The role of health literacy in the association between academic performance and substance use.
2022
Abstract Background To address social inequalities in adolescent substance use and consequent disparities in health, it is important to identify the mechanisms of the association between substance use and academic performance. We study the role of health literacy (HL) in the association between academic performance and weekly smoking, monthly alcohol use and cannabis ever-use among adolescents in Europe. Methods SILNE-R school survey data, which was collected in 2016–17 with paper-and-pencil-method from Hanover (GE), Amersfoort (NL) and Tampere (FI), were used (N = 5088, age 13–19). Health Literacy for School-aged Children instrument was used to assess students’ HL. Logistic regression anal…
The sanitation service of seagrasses – Dependencies and implications for the estimation of avoided costs
2022
Seagrasses are capable of sanitizing coastal seawaters polluted by fecal bacteria. In this work, the reduction of Enterococci concentration in the presence of a seagrasses’ assemblage (Pacific Ocean) was related to the decrease in the probability of gastroenteritis. A linear model fitted to data extracted from the literature showed a 20% reduction of this probability in the presence of these plants. Seagrass sanitation effect was estimated to allow avoiding ca. 24 million gastroenteritis cases/year, globally. Considering a global cost of gastroenteritis of ca. US$ 372 million/year, the global avoided cost, assuming that the sanitation service was always effective, was estimated to be ca. US…
Oblique angle co-deposition of nanocolumnar tungsten thin films with two W sources: Effect of pressure and target current
2022
Two series of tungsten thin films are sputtered on silicon and glass substrates by oblique angle co-deposition technique with an original configuration. Two opposite distinct tungsten targets are simultaneously used, both tilted with an oblique angle of 80°. The growth is performed at low (0.33 Pa) and high (1.5 Pa) argon sputtering pressure and the current intensity applied to the targets varies between 50 and 250 mA. The effect of these deposition parameters on the films microstructure and electrical properties is investigated by scanning and transmission electron microscopy, X-ray diffraction and pole figures, and van der Pauw method. Due to self-shadowing effect, all tungsten sputtered …
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 …
Inquadramento clinico del paziente vasculopatico
2022
Le patologie vascolari sono uno dei più rilevanti problemi per la sanità nazionale e quindi rappresentano una importante branca della medicina. I segni, le manifestazioni e le evoluzioni delle malattie vascolari vanno spesso integrati con altre patologie capaci di influenzarne il percorso. L’aumento della durata della vita, con il conseguente invecchiamento della popolazione, rende il paziente vasculopatico una figura presente costantemente negli ambulatori di medicina. I dati dell’Istituto Nazionale di Statistica (ISTAT) riportano che in Italia l’età media della popolazione è di 44,9 anni e che la fascia di popolazione con età superiore a 65 anni è del 22,3%. Inoltre l’Italia è il Paese ch…

Similar but Different? The influence of job satisfaction, organizational commitment and person-job fit on individual performance in the continuum bet…
2022
Permanent organizations and temporary organizations, such as projects, represent two poles of a continuum of organizational temporariness. The literature has shown that organizational temporariness can influence organizational outcomes and employee behavior. Using a sample of 341 members of temporary organizations, we investigate job satisfaction and organizational commitment in a permanent organization and person-job fit in a temporary organization as antecedents of employee performance. We further examine how the degree of organizational temporariness moderates these relationships. The findings show that job satisfaction and organizational commitment negatively influence employee performa…
Review on mechanical joining by plastic deformation
2022
Mechanical joining technologies are increasingly used in multi-material lightweight constructions and offer opportunities to create versatile joining processes due to their low heat input, robustness to metallurgical incompatibilities and various process variants. They can be categorised into technologies which require an auxiliary joining element, or do not require an auxiliary joining element. A typical example for a mechanical joining process with auxiliary joining element is self-piercing riveting. A wide range of processes exist which are not requiring an auxiliary joining element. This allows both point-shaped (e.g., by clinching) and line-shaped (e.g., friction stir welding) joints t…
Brevi considerazioni sulla necessità di emancipare la vittima del reato dallo «status» di offeso
2022
Con la sentenza 203/2021, la Corte costituzionale ha dichiarato non fondata la questione di legittimità costituzionale dell'art. 2, comma 2 bis, l. 24 marzo 2001 n. 89: continua, pertanto, a rimanere esclusa dal novero dei legittimati a dolersi dell'eccessiva durata dell'iter procedimentale la vittima del reato, la quale, ancorché abbia subìto un patimento cagionato dall'eccessivo protrarsi delle indagini preliminari cui consegua l'estinzione del reato per prescrizione e quantunque abbia presentato querela ed esercitato i diritti e le facoltà accordatele dall'ordinamento nella veste proprio di persona offesa, non avrà diritto a beneficiare del rimedio ristorativo previsto dalla legge Pinto,…
Enlarged PLIN5-uncoated lipid droplets in inner regions of skeletal muscle type II fibers associate with type 2 diabetes
2022
Skeletal muscle physiology remains of paramount importance in understanding insulin resistance. Due to its high lipid turnover rates, regulation of intramyocellular lipid droplets (LDs) is a key factor. Perilipin 5 (PLIN5) is one of the most critical agents in such regulation, being often referred as a protector against lipotoxicity and consequent skeletal muscle insulin resistance. We examined area fraction, size, subcellular localization and PLIN5 association of LDs in two fiber types of type 2 diabetic (T2D), obese (OB) and healthy (HC) individuals by means of fluorescence microscopy and image analysis. We found that T2D type II fibers have a significant sub-population of large and inter…
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 …
Evolution of the optimal catalytic systems for the oxidative dehydrogenation of ethane: The role of adsorption in the catalytic performance
2022
Three samples that correspond to the evolution of optimal catalytic systems for the oxidative dehydrogenation of ethane have been synthesized and compared in terms of catalytic behavior and adsorption properties: (i) vanadium oxide supported on alumina, (ii) Sn-promoted NiO, and (iii) multicomponent MoVTeNbO with the M1 structure. The main difference in catalytic performance lies in the extent of the overoxidation of the ethylene formed, following the order VOx/Al2O3 > NiSnOx > MoVTeNb-M1. Accordingly, the selectivity to ethylene at medium and high ethane conversion follows the order MoVTeNb-M1 > NiSnOx > VOx/Al2O3. These results are confirmed by the relative reaction rates observed for the…
Diversità di genere e sistema sanitario: un’analisi su un campione di aziende sanitarie italiane
2022
Il lavoro analizza in che misura la diversità di genere fa parte delle attuali pratiche delle aziende sanitarie. Attraverso un’analisi di tipo statistico-inferenziale su un campione di 39 strutture ospedaliere appartenenti al Gruppo San Donato, ha lo scopo di valutare se la presenza delle donne nel CdA influenza la performance aziendale. I risultati suggeriscono che la diversità nelle aziende sanitarie è un tema poco esplorato e non mancano opportunità e ostacoli al percorso di carriera delle donne. L’analisi di correlazione e regressione conferma che la presenza delle donne è positivamente correlata all’indice di performance delle strutture; la strada per arrivare alla parità non è breve e…

The dark side of phubbing in the workplace: Investigating the role of intrinsic motivation and the use of enterprise social media (ESM) in a cross-cu…
2022
Despite the increasing phenomena of supervisor phubbing (a counterproductive workplace behaviour of managers), very few studies have explored its outcomes in organisations. This study aims to bridge this gap by investigating the relationships between supervisor phubbing and key employee outcomes. We conducted two studies in cross-cultural settings. In Study 1, which was conducted in Pakistan (a collectivistic culture), we collected 370 useable responses through an online survey from the employees working in the service sector organisations. Study 2, which was conducted in the United States of America (an individualistic culture), utilised the Prolific data collection service to gather 352 r…
The impact of retro-cue validity on working memory representation: Evidence from electroencephalograms.
2022
Visual working memory (VWM) performance can be improved by retrospectively cueing an item. The validity of retro-cues has an impact on the mechanisms underlying the retro-cue effect, but how non-cued representations are handled under different retro-cue validity conditions is not yet clear. Here, we used electroencephalograms to investigate whether retro-cue validity can affect the fate of non-cued representations in VWM. The participants were required to perform a change-detection task using a retro-cue with 80% or 20% validity. Contralateral delay activity and the lateralized alpha power were used to assess memory storage and selective attention, respectively. The retro-cue could redirect…
Empirical study of multidimensional Child-Langmuir law with plasma ion source extraction using round apertures
2022
Abstract One dimensional Child-Langmuir (CL) law is commonly used in ion source physics to describe space charge limited ion extraction from the plasma. Recently 2D and 3D CL laws have been derived, but plasma ion extraction does not strictly meet the assumptions in these CL laws. Investigations on the applicability of the CL laws to ion source extraction were conducted using filament-driven ion source, measuring the beam currents as a function of extraction voltage. The experiments are complemented with simulations where IBSimu is used for studying the behaviour of plasma meniscus. Three different voltage regions were identified with low, moderate and high voltage. With moderate voltages t…
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.
La partecipazione popolare al procedimento legislativo prevista dallo Statuto: vincolo giuridico o politico-parlamentare?
2022
This paper aims to analyze the participation of organized interests in the legislative process, disciplined by the article 12.3 of the Sicilian Statute. The results of the research show that no other regional statute, and not even the Rules of procedure of the two chambers of the Parliament, adopts the same mechanism of participation. The Sicilian Statute can be considered an interesting example of how the decision- making process can include organized interests as already experimented with the public debate on large infrastructures.
Challenge Demands and Resilience
2022
Abstract. This study investigates the relationship of challenge demands (i. e., time pressure, job complexity) on employee resilience. We provide insights into potential pathways (i. e., learning, cognitive irritation) for how challenge stressors influence employee resilience. We employed a two-wave, time-lagged design to examine the influences of challenge stressors and explanatory pathways on employee resilience 2 months later. The data from 359 participants (52.1 % male) were analyzed using a Bayesian time-lagged path model. Results indicate that time pressure and job complexity are negatively related to employee resilience via cognitive irritation. In contrast, we found a positive, ind…
Yeast interaction on Chardonnay wine composition: Impact of strain and inoculation time.
2022
Abstract It is of great importance to understand the molecular characteristics and substantial chemical transformations due to yeast-yeast interaction. Non-targeted metabolomics was used to unravel must in fermentation composition, inoculated with non-Saccharomyces (NS) yeasts and Saccharomyces cerevisiae (S) for sequential fermentation. ultrahigh-resolution mass spectrometry was able to distinguish thousands of metabolites and provides deep insights into grape must composition allowing better understanding of the yeast-yeast interactome. The dominance of S, characterized by a metabolic richness not found with NS, is dependent on inoculation time and on the yeast species present. Co-inocula…
The Emerging Role of Dual GLP-1 and GIP Receptor Agonists in Glycemic Management and Cardiovascular Risk Reduction
2022
The incretin pathway is a self-regulating feedback system connecting the gut with the brain, pancreas, and liver. Its predominant action is on the postprandial glucose levels, with extraglycemic effects on fat metabolism and endovascular function. Of the two main incretin hormones released with food ingestion, the actions of glucagon-like peptide-1 (GLP-1) have been exploited for therapeutic benefit. However, little attention has been paid to glucose-dependent insulinotropic polypeptide (GIP) until the recent experimental introduction of dual agonists, or "twincretins". Interestingly, simultaneous activation of both receptors is not only replicative of normal physiology, it seems to be an i…
The role of psychological inflexibility in adolescent satisfaction with the educational track and school dropout intentions
2022
This study aimed to obtain novel understanding of the associations between psychological inflexibility and adolescents' engagement with upper secondary studies. The participants were 885 Finnish adolescents (mean age 15.74 at the outset) whose psychological inflexibility was measured with the short form of the Acceptance and Fusion Questionnaire for Youth (AFQ-Y8) in the fall of the final (ninth) grade of basic education. School engagement was measured as satisfaction with the educational track and as school dropout intentions, and they were measured twice in the first study year after the transition to upper secondary education. The results showed that high psychological inflexibility in t…
