A Territorial-driven approach to capture the transformative momentum of the Social Economy especially from the agricultural cooperatives
2021
In the last few lustrums, the literature has searched for more precise methods to assess the socio-economic importance of the Social and Solidarity Economy (SSE). On that basis, this article offers a new way of assessing the SSE impact, enhancing the understanding of the SSE potential for socio-economic transformation. An evolutionary micro–meso–macro and territorial theoretical framework is developed, utilizing, along with the assistance of a qualitative methodology, studies on the transformation promoted by the SSE on the sugar cane cluster of Veracruz (Mexico). The main results of the article are that the SSE boost beneficiaries, while the protagonists of the transformation c…

Exploring travelers’ willingness to pay for green hotels in the digital era
2021
The past few years have witnessed an intensifying effort by hotels to respond to customers’ growing environmental sensitivities. A critical aspect of this market trend is the actual willingness of tourists to pay (WTP) for green products and services offered by green hotels. Previous studies in this research field have mainly focused on the relationship between guests’ attitudes and their behavioral intentions, neglecting the influence of external and situational factors. In light of this, the present paper contributes to knowledge by analyzing the influence of e-Word-of-Mouth (e-WOM) and physical image, as it emerges from digital platforms, and the effect of green hotel attributes on the t…
Ulisse modello di decorum: a proposito di Cic. Tusc. 2, 48-50.
2021
The paper deals with the character of Ulysses within the frame of the Tusculanae disputationes with a particular focus on the sequence 2, 48-50. The comparison between the hero and other mythological figures (e.g. Philoctetes) allows us to observe the role of Ulysses as a model for decorum, analysing at the same time the way in which Cicero reinterprets actions and behavior of the character starting from the fragments of Pacuvius’ Niptra.
Aloe-Based Edible Coating to Maintain Quality of Fresh-Cut Italian Pears (Pyrus communis L.) during Cold Storage
2021
Pear fruits are known for their antioxidant and nutritional characteristics. However, they are very susceptible to rapid decay. Edible coating (EC) represents a good strategy to maintain postharvest quality. The effects of two EC in slowing down the senescence processes in fresh-cut ‘Coscia’ pears were investigated: EC1 (A. vera gel, hydroxypropyl-methylcellulose and pomegranate seeds oil (PSO), EC2 (A. vera gel and hydroxypropyl-methylcellulose). Weight loss, firmness and colour decrease more slowly in both EC-treated than in untreated (CTR) slices; soluble solid content increases faster in CTR, indicating a faster ripening process. The specific investigation of undesired microorganisms di…
Controlling Oxidative Addition and Reductive Elimination at Tin(I) via Hemi-Lability.
2021
We report on the synthesis of a distannyne supported by a pincer ligand bearing pendant amine donors that is capable of reversibly activating E–H bonds at one or both of the tin centres through dissociation of the hemi-labile N–Sn donor/acceptor interactions. This chemistry can be exploited to sequentially (and reversibly) assemble mixed-valence chains of tin atoms of the type ArSn{Sn(Ar)H} n SnAr ( n = 1, 2). The experimentally observed (decreasing) propensity towards chain growth with increasing chain length can be rationalized both thermodynamically and kinetically by the electron-withdrawing properties of the –Sn(Ar)H– backbone units generated via oxidative addition. peerReviewed

Lower limb muscle strength and muscle mass are associated with incident symptomatic knee osteoarthritis: a Longitudinal Cohort Study
2021
Recent literature suggests that sarcopenia, often represented by low lower limbs muscle mass and strength, can be considered a potential risk factor for knee osteoarthritis (OA), but the available literature is still limited. We therefore aimed to investigate whether sarcopenia is associated with a higher risk of radiographic (ROA) and symptomatic knee OA (SxOA) in a large cohort of North American people in the context of the OA initiative. Sarcopenia at baseline was diagnosed in case of low skeletal muscle mass (i.e., lower skeletal mass index) and poor performance in the chair stands test. The outcomes of interest for this study included ROA (radiographical osteoarthritis) if a knee devel…
Cognitive Frailty: An Update
2021
This review article provides an update of the empirical research on cognitive fragility conducted in the last four years. The studies retrieved were classified in four different categories. The first category includes articles relating cognitive frailty to cognitive reserve and which continue to highlight the importance of educational level. The second category includes recent research on cognitive fragility biomarkers, involving neuroimaging, metabolism and, in a novel way, microbiota. The third category includes research on how cognitive frailty is related to motor development and physical functioning, exploring e.g. the use of technology to study motor markers of cognitive frailty. Final…
Arendt, Eichmann and the Politics of the Past
2021
Part of the Pro et Contra series. Arendt, Eichmann and the Politics of the Past offers a critical analysis of the original American debate over Hannah Arendt’s report of the trial of Adolf Eichmann. First published in 2008, Tuija Parvikko’s book discusses both the campaign against Arendt organised by American Zionist organisations and the controversy Arendt’s report caused within American Jewish intellectual circles. Parvikko’s analysis carefully draws from the historical background of the report, discussing Arendt’s early studies of Zionism and her critique of the Jewish state. The volume also gives an account of Eichmann’s capture in Argentina and the reception of the report among legal s…

Assessment of sleep disturbances with the athlete sleep screening questionnaire in Chinese athletes.
2021
This study investigated the factors that are associated with sleep disturbances among Chinese athletes. Sleep quality and associated factors were assessed by the Athlete Sleep Screening Questionnaire (ASSQ, n = 394, aged 18–32 years, 47.6% female). Sleep difficulty score (SDS) and level of sleep problem (none, mild, moderate, or severe) were used to classify participants' sleep quality. Categorical variables were analyzed by Chi-square or fisher's exact tests. An ordinal logistic regression analysis was used to explore factors with poor sleep (SDS ≥8). Approximately 14.2% of participants had moderate to severe sleep problem (SDS ≥8). Fifty-nine percent of the athletes reported sleep distu…

Cardiac Remodeling According to the Nocturnal Fall of Blood Pressure in Hypertensive Subjects: The Whole Assessment of Cardiac Abnormalities in Non-D…
2021
Objective: Several epidemiological studies suggest that the preservation of the physiological circadian rhythm of blood pressure or its disruption affects the extent of the organ damage developed by the patient. If we classify the circadian rhythm of blood pressure into four nocturnal profiles, significant differences emerge in terms of organ damage burden and prognosis: reverse dippers have the worst prognosis while dippers and mild dippers fall into an intermediate risk range. The risk profile of extreme dippers is still debated, and the available data are very conflicting and inconclusive. Starting from this gap of knowledge, we aimed to evaluate, retrospectively, in a cohort of hyperten…
Resistenza a taglio di campioni rimaneggiati di Opalinus Clay
2021
La nota presenta una selezione dei risultati di un ampio programma sperimentale condotto con l’obiettivo di caratterizzare, dal punto di vista della resistenza a taglio, dei campioni rimaneggiati di Opalinus Clay, attraverso l’esecuzione di prove triassiali non convenzionali. I risultati mostrano chiaramente l’influenza del grado di preconsolidazione sul comportamento meccanico del geomateriale e in particolare sulla resistenza a taglio, che risulta caratterizzata da un picco di resistenza poco marcato e da un comportamento dilatante. La presenza di giunti all’interno del provino altera completamente il comportamento originario del materiale, che diventa duttile e contraente. Inoltre, in ta…
Un’altra geografia è possibile. Annotazioni sparse a partire da Geografia come immaginazione di Giuseppe Dematteis
2021
In un suo celebre saggio, pubblicato nel 1992, Stuart Hall proponeva di immaginare il lavoro teorico come una “lotta con gli angeli”. Raccontando del suo incontro da lettore con Althusser, scriveva: “La sola teoria che abbia valore è quella con cui si deve combattere, non quella di cui si parla in modo disinvolto” (Hall, 2006, p. 289). I libri – o, meglio, le letture – per cui vale la pena hanno in sé la capacità di interrogarci, di disturbarci, di manomettere i nostri sistemi di teorie, rappresentazioni, immaginazioni. È quel che da sempre mi accade con gli scritti di Giuseppe Dematteis ed è anche dentro e attraverso queste lotte che si è costruito il mio modo di fare geografia e di stare …

Changes in Drop Out Intentions: Implications of the Motivational Climate, Goal Orientations and Aspects of Self-Worth across a Youth Sport Season
2021
The main objective of this work was to study the motivational antecedents of the intention to drop out of youth sport from the postulates of the achievement goal theory (AGT), placing special emphasis on the motivational climate that coaches create in their teams. Specifically, we analyzed whether changes in the perception of the motivational climate between the beginning and the end of the season predicted changes in players’ goal orientations, whether these, in turn, predicted changes in self-esteem and contingent self-esteem, and finally, whether the latter predicted the intention to drop out. Participants in the study were 552 players (Mage = 11.23, SD = 1.14), who completed the questio…

Efficiency advantages of the separated electric compound propulsion system for CNG hybrid vehicles
2021
As is widely known, internal combustion engines are not able to complete the expansion process of the gas inside the cylinder, causing theoretical energy losses in the order of 20%. Several systems and methods have been proposed and implemented to recover the unexpanded gas energy, such as turbocharging, which partially exploits this energy to compress the fresh intake charge, or turbo-mechanical and turbo-electrical compounding, where the amount of unexpanded gas energy not used by the compressor is dedicated to propulsion or is transformed into electric energy. In all of these cases, however, maximum efficiency improvements between 4% and 9% have been achieved. In this work, the authors d…

Slow Pyrolysis as a Method for Biochar Production from Carob Waste: Process Investigation and Products’ Characterization
2021
The zero-waste city challenge of the modern society is inevitably addressed to the development of model’s waste-to-energy. In this work, carob waste, largely used in the agro-industrial sector for sugar extraction or locust beangum (LBG) production, is considered as feedstock for the slow pyrolysis process. According to the Food and Agriculture Organization of the United Nations (FAO), in 2012, the world production of carobs was ca. 160,000 tons, mainly concentrated in the Mediterranean area (Spain, Italy, Morocco, Portugal, and Greece). To evaluate the biomass composition, at first, the carob waste was subjected to thermo-gravimetric analysis. The high content of fixed carbon suggest…
