GREEN ENERGY HARVESTING FROM CONCENTRATED SALTWORKS BITTERNS BY REVERSE ELECTRODIALYSIS
2022
Concentrated bitterns discharged from saltworks have extremely high salinity, often up to 300 g/L, thus their direct disposal not only can have harmful effect on the environment, but also generates a depletion of a potential resource of renewable energy. Here, reverse electrodialysis (RED), an emerging electrochemical membrane process, is introduced to capture the salinity gradient power (SGP) intrinsically conveyed by these bitterns also aiming at the reduction of concentrated salty water disposal. A RED unit at the laboratory scale has been adopted to study the SGP potential with different ion exchange membrane and different operating conditions. In particular, membranes supplied by Fujif…

Per una classe dirigente autonoma, performante e responsabile
2022
Il saggio intende mettere in luce il filo conduttore del percorso riformatore, ormai trentennale, del nuovo modello di rapporti tra politica e amministrazione. Oggetto specifico dell’indagine sono il principio della distinzione delle funzioni di indirizzo e controllo politico-amministrativo e i principi correlati dell’autonomia, della valutazione della performance e della responsabilità dirigenziale. Vengono in particolare analizzate le cause che hanno finora impedito lo sviluppo di una classe dirigente realmente autonoma nelle decisioni (e resistente agli eventuali condizionamenti impropri della classe politica) e soprattutto performante e responsabile dei risultati che produce nell’intere…

2022
River restoration aims to apply environmentally-friendly structures for bank protection in meandering rivers to restore their natural habitat. Enhanced Permeable Groin (EPG) is a novel river restoration technique that can improve the fish habitat environment in a river system by creating a series of eco-friendly scour pools. This study reports the results of two groups of 3D velocity measurements in a 180-degree channel bend in cases with and without an EPG for clear water conditions to characterize the mechanisms leading to the primary stages of the scouring phenomenon. The analysis revealed that the presence of an EPG amplified the velocity magnitude in the regions near the tip of the van…
Corporate entrepreneurship and governance: Mergers and acquisitions in Europe
2022
Mergers and acquisitions (M&A) are a form of corporate entrepreneurship involving strategic decisions that require discussion and approval by the board of directors of the acquiring firm. We focus on board attributes to analyze the entrepreneurial function of the board of directors and its involvement in corporate entrepreneurship. Building on different theories (agency theory, resource dependence theory, stewardship theory, and stakeholder theory), we examine whether board composition affects the number of acquisitions, the risk involved in bids, and the creation of value for the acquirer's shareholders. For a sample of European firms over the period 2002 to 2020, we find that board size a…

Evaluating of the sustainability of complex rural ecosystems during the transition from agricultural villages to tourist destinations and modern agri…
2022
Many agricultural villages have transformed from traditional agricultural communities into tourist destinations to eliminate the progressive degradation, abandonment, ecological and social crises that threaten sustainable development. Today rural villages are complex ecosystems that represent the result of the historical relationship between man and nature in the socio-economic dimension. A tool for assessing the sustainability of rural villages is the analysis of the interaction between man and the environment. Preserving healthy rural ecosystems, in dynamic balance with the interrelation between social development and the functioning of the natural ecosystem is an indispensable goal of su…
Grid Stability Improvement Using Synthetic Inertia by Battery Energy Storage Systems in Small Islands
2022
In this paper, the synthetic inertia need of the small island of Pantelleria in the Mediterranean Sea is assessed. Firstly, the optimal renewable energy mix able to minimize the Levelized Cost of Energy for the generation system of the island is evaluated, considering the yearly load demand and the characteristics of the local natural resources. The optimal energy mix introduces in the island a quota of power generation with static power converters interfaced to the grid that could jeopardize the security of the system if not suitably controlled. Therefore, the inherent inertial response of the diesel generators of the system is calculated hour by hour for each month of one year, considerin…
Wireless software and hardware platforms for flexible and Unified Radio and Network Control (WiSHFUL)
2022
In the last years, we have assisted to an impressive evolution of wireless technologies for short distance communication (like IEEE 802.11, IEEE 802.15.4. Bluetooth Low Energy, etc.) due to the need of coping with the heterogeneous requirements of emerging applications, such as Internet of things, the Industry 4.0, the Tactile Internet, the ambient assistant living, and so on. Indeed, for optimizing the technology performance in these scenarios, it is often required to support some forms of protocol adaptation, by allowing the dynamic reconfiguration of protocol parameters and the dynamic activation of optional mechanisms, or some targeted protocol extensions.In both cases, prototyping, tes…

Reliģiski-filozofiski raksti XXXII ir par telpas pieredzēšanu: par to, kā mēs izdzīvojam sevi vietā, kurā esam, un kā mēs izjūtam sevi šajā savā vietā vai vietā, kura tā arī nav kļuvusi vai nekad nebūtu varējusi kļūt par mūsu dzīves pasauli. Kā veidojas šī savas vietas izjūta? Vai vieta, kurā mēs dzīvojam, vienmēr ir mājas? Vai šo vietas izjūtu veido mūsu individuālā pieredze vai varbūt tā ir vairāk atkarīga no kādām kolektīvām prasībām? Varbūt to nosaka mūsu piederība tradīcijām, kurās esam audzināti un kuras arī saucam par savām, bet varbūt tieši mūsu vietas pieredze ir tā, kas nosaka to, kādai tradīcijai mēs izvēlamies piederēt vai kuras veidošanā piedalāmies?

Giotto’s legacy and western Sicily. The restoration of a late 14th century Maiestas Domini in the Basilica of San Francesco d’Assisi in Palermo, Italy
2022
Tra novembre 2019 e luglio 2020, l'intervento di restauro di un dipinto murale raffigurante la "Maiestas Domini", situato all'interno della Basilica di San Francesco d'Assisi a Palermo, è stato l'occasione per intraprendere un percorso di indagine tecnica e storico-artistica che ha approfondito lo stretto legame tra la Sicilia e le manifestazioni pittoriche "post-giottesche", con particolare attenzione alle opere d'arte su supporto murario e al ruolo svolto dall'iconografia all'interno della tradizione figurativa locale, tra eredità dell'arte normanna e influenze toscane e iberiche Between November 2019 and July 2020, the restoration of a mural painting depicting the "Maiestas Domini," loca…
THE SCHOOL AT THE SERVICE OF THE SOCIETY: CONSEQUENCES FOR THE "NEW WORLD"
2022
Introduction In this article I shall seek to demonstrate the remarkable contemporary relevance of John Dewey’s pedagogic ideas, found in publications such as My Pedagogic Creed, The School and Society and Democracy and Education. Through a brief analysis of these works I will highlight how much Dewey believed in a school that is connected to society and which places itself at its service, contributing to the birth or consolidation of a democracy understood not just as a form of government, but as a way of life. In view of this analysis and in light of the present pandemic caused by COVID-19, I will consider the importance today of the school. Following Dewey, I will take into account the ro…
Exploring the conceptual framework and measurement model of intrinsic capacity defined by the World Health Organization: A scoping review
2022
WHO has defined intrinsic capacity (IC) as the composite of all physical and mental capacities of an individual covering five subdomains: cognition, locomotion, sensory, vitality, and psychological. Despite this well accepted definition, the conceptual and measurement model of IC remains unclear, which hampers a standardized operationalization of the construct. We performed a scoping review to give a comprehensive overview of the extent to which the current literature of IC addresses and assumes the conceptual framework and measurement model of IC as reflective or formative. For inclusion, we considered all types of articles that were published in peer-reviewed journals except for protocol …
Distracted driving in relation to risky road behaviors and traffic crashes in Bogota, Colombia
2022
The growing evidence on road distraction during the recent years has shown how road distractions might be playing a relevant role on traffic crash causation. However, the empirical insights about how it works in low- and middle-income countries (LMICs) are really limited so far. The case of Colombian non-professional drivers remains virtually unexplored on this regard. This research aims to assess the effect of road distractions, driving-related issues and road behaviors on the self-reported crashes suffered by drivers in Bogotá, Colombia. To do so, a sample of 659 drivers (64% males and 36% females) with a mean age of 37.9 years (SD = 11.7) was gathered, who answered an online survey on ro…
In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries
2022
Contains fulltext : 284232.pdf (Publisher’s version ) (Closed access) The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., "If you do not practice these steps, you can endanger yourself and others") or potential gains (e.g., "If you practice these steps, you can protect yourself and others")? Collecting data in 48 languages from 15,929 participants in 84 countries, we…
Le grafie e le visioni in Oltremare di Umberto Di Segni
2022
Between the end of 1993 and the beginning of 1994, the Galleria d’Arte Moderna in Bologna held an extraordinary exhibition on Italian architecture in the overseas territories, accompanied by a catalogue which, through period drawings and photos, gave an insight into a very interesting moment in the history of Italian architecture. The “Quarta Sponda”, at that time thought of as the nineteenth region of the Homeland, was to be a true extension of Italy that would be inhabited, according to a well-defined colonisation programme, by one hundred thousand colonists.The role of architecture was central to the process of founding new agglomerations and representative buildings envisaged by the Fas…
Freud "rivisto". Nuove interpretazioni femministe dello sguardo
2022
Gli studi sullo sguardo femminile hanno ormai una lunga anche se forse non consolidata tradizione interdisciplinare che risale almeno agli anni ’70 del Novecento. Se è stato di sicuro l’ambito dei Film Studies, e soprattutto quello dei Feminist Film Studies, ad aver dato un imprescindibile impulso a questi studi (è scontato riferirsi all’ormai classico Visual Pleasure and Narrative Cinema di Laura Mulvey così come agli studi di Mary Ann Doane) alla fine del Novecento e all’inizio del ventunesimo secolo la messa in questione di una “differenza” di genere all’interno delle pratiche, delle tecnologie, delle specificità dello sguardo si è allargata ad ambiti diversi. In questo saggio ci concent…

Stability and transitions in school-aged children's physical education need satisfaction profiles : A latent transition analysis
2022
This study examined stability and transitions of school-aged children's self-determination theory-based need satisfaction profiles in physical education (PE) over three years. Participants were 1121 (girls 573, boys 548) Finnish school children. The self-report data were assessed using identical procedures from 2017 to 2020. Three latent need satisfaction profiles were identified: Low, Mid, and High need satisfactions. Transitions mainly occurred between grade 5 and 6 in elementary school, after which the profile memberships remained relatively stable. The profile memberships were not school- or PE group dependent over time. These results indicate that school-based actions to achieve a posi…
Tra terra, mare e cielo: le terrazze del raccontare di Giorgio Caproni
2022
Nel saggio sono indagati i multiformi significati e le diverse declinazioni attribuite agli spazi domestici nella produzione di Giorgio Caproni. Partendo dalla disamina di "La Maliarda" e passando in rassegna altri racconti caproniani, vengono individuate alcune costanti tematiche e la funzione meta narrativa associata al topos della terrazza. Essa, territorio di confine tra terra, mare e cielo, è infatti luogo privilegiato delle “città dell’anima”, è spazio del paradosso, della memoria e, soprattutto, luogo della narrazione.

Strategic choice in times of stagnant growth and uncertainty: An institutional theory and organizational change perspective
2022
This conceptual study provides insight into the strategic behaviors of firms facing slow growth in times of economic stagnation. Recognizing the inevitability of periods of economic stagnation—with another downturn expected as early as 2022, we note that most industry classifications are considered mature and characterized by a few extremely large companies in each industry group. We introduce the Fortune 500 as an important cross-industry collective of these large firms and suggest that they now comprise an institutional field. This development explains their isomorphic behavior during the recession triggered by the financial crisis of 2008 as well as their subsequent motivation for change…
Significance of immunohistochemistry biomarkers in prediction of malignant transformation of oral lichen planus
2022
Background: Oral lichen planus (OLP) is a chronic inflammatory disorder with increased risk for malignant transformation. Biomarker validation is a pivotal step in moving newly discovered biomarkers towards clinical implementation. We performed a systematic review of studies on biomarkers related to OLP, wherein biomarkers have been described in at least two independent studies. Our aim was to determine whether any of these biomark-ers might be promising in predicting the increased risk of malignant transformation of OLP. Material and Methods: We searched the following databases until August 2021: PUBMED, EMBASE, and Web of Science. Due to high heterogeneity, a qualitative rather than quant…
