School-family relationship: a survey on the communicative and participatory methods of non-indigenous families
2022
Il complesso processo educativo basato sull’educazione delle giovani generazioni comporta un’assunzione di responsabilità da parte delle due principali agenzie educative: la famiglia e la scuola. Per la buona riuscita del processo educativo è necessario che tra le due agenzie ci sia un accordo implicito o esplicito sugli aspetti terminologici e concettuali, affinché si stabilisca una comprensione comune per gli interlocutori e si crei un contesto chiaro e trasparente che non lasci spazio a interpretazioni fallaci (Quaranta, 2019). I cambiamenti socioculturali hanno determinato un pluralismo culturale, religioso e nuove sfide tecnologiche e problematiche comunicative e partecipative (Pati, 2…
Imaging standardisation in metastatic colorectal cancer: a joint EORTC-ESOI-ESGAR expert consensus recommendation
2022
Background: Treatment monitoring in metastatic colorectal cancer (mCRC) relies on imaging to evaluate the tumor burden. Response Evaluation Criteria in Solid Tumors (RECIST) provide a framework on reporting and interpretation of imaging findings yet offer no guidance on a standardized imaging protocol tailored to mCRC patients. Imaging protocol heterogeneity remains a challenge for the reproducibility of conventional imaging endpoints and is an obstacle for research on novel imaging endpoints. Patients and methods: Acknowledging the recently highlighted potential of radiomics and artificial intelligence (AI) tools as decision support for patient care in mCRC, a multidisciplinary, internatio…
Tra due poli: fonti e caratteri giuridico-istituzionali dei rapporti tra Papato e vescovati siciliani in età normanna (secc. XI-XII)
2022
The aim of this work is to examine the sources relating to the legalinstitutional relations between the Papacy and the bishoprics of the island of Sicily, between the 11th and 12th centuries. The investigation aims to verify in what ways, and according to what forms, each pope directed his action to get in touch with the bishops in charge of the different ecclesiastical sees. On the other hand, it is also intended to examine whether the Sicilian bishops themselves attempted in some way to accredit their action towards the Apostolic See. The two poles evoked in the title – the Sicilian Monarchy and the Church of Rome – represent respectively the two highest authorities for the Churches of th…
The system of protected areas as the core element in a new vision of the Metropolitan City of Palermo
2022
Un processo di urbanizzazione può certamente essere considerato una delle più significative alterazioni antropiche del sistema ambientale in un territorio. Il presente studio vuole comprendere le caratteristiche spaziali della crescita urbana e i suoi impatti sulle componenti ambientali nella Città Metropolitana di Palermo, un'area in cui i livelli di consumo di suolo inedificato e di pregio, e le conseguenti forme di frammentazione ambientale e territoriale, rischiano di compromettere non solo il valore paesaggistico-ambientale dei territori coinvolti ma anche la loro identità. Partendo da queste premesse, questo contributo esplora il rapporto di reciprocità tra ambiente costruito e territ…
Challenges and opportunities for citrus wastewater management and valorisation: A review.
2022
Citrus wastewaters (CWWs) are by-products of the citrus fruit transformation process. Currently, more than 700 million of m³ of CWWs per year are produced worldwide. Until nowadays, the management of CWWs is based on a take-make-use-dispose model. Indeed, after being produced within a citrus processing industry, CWWs are subjected to treatment and then discharged into the environment. Now, the European Union is pushing towards a take-make-use-reuse management model, which suggests to provide for the minimization of residual pollutants simultaneously with their exploitation through a biorefinery concept. Indeed, the recovery of energy nutrients and other value-added products held by CWWs may…

Integration of lot sizing and safety strategy placement using interactive multiobjective optimization
2022
We address challenges of unpredicted demand and propose a multiobjective optimization model to integrate a lot sizing problem with safety strategy placement and optimize conflicting objectives simultaneously. The novel model is devoted to a single-item multi-period problem in periodic review policy. As a safety strategy, we use the traditional safety stock concept and a novel concept of safety order time, which uses a time period to determine the additional stock to handle demand uncertainty. The proposed model has four objective functions: purchasing and ordering cost, holding cost, cycle service level and inventory turnover. We bridge the gap between theory and a real industrial problem a…

PNRR, lavoro pubblico e dintorni
2022
La legislazione di attuazione del PNRR contiene misure sul reclutamento e sulla progressione di carriera del personale pubblico, nonche´ sulla dirigenza, dirette allo scopo del rafforzamento della capacita` amministrativa delle istituzioni pubbliche. Esse presentano alcune luci e molte ombre su cui vale la pena soffermarsi. Peraltro, i grandi processi di trasformazione e transizione in atto reclamano un forte coinvolgimento delle parti sociali per garantire una loro gestione e una (auspicabile) crescita economica socialmente eque e sostenibili.
Che cos'è la filosofia? L'essenza della filosofia oltre la distinzione fra analitici e continentali
2022
Porsi la domanda che «cos’è la filosofia?» significa già fare filosofia, e trovarsi nella condizione dell’esule, dello spaesato. La filosofia, sostiene Heidegger, è un campo vasto e indeterminato; “indeterminato” significa che il pensatore, non appena viene posta la domanda sulla definizione della sua attività, si ritrova in qualche modo estraniato rispetto all’elemento del suo operare. La determinazione della filosofia è opera di quanti cooperano alla costruzione del sapere, nei suoi ambiti disparati, e preservano, ad un tempo, il senso stesso dell’indeterminatezza. Non esistono ambiti del sapere che non possano essere anche filosofici, né si possono limitare a priori i temi, le linee di r…

Optimal selection of touristic packages based on user preferences during sports mega-events
2022
Sport mega-events, such as the Soccer World Cup or Olympic Games, attract many visitors from all over the world. Most of these visitors are also interested in, besides attending the sports events, visiting the host nation and the neighboring countries. In this paper, we focus on the upcoming FIFA World Cup Qatar 2022. As per the schedule of the tournament, a national team can play 7 matches at most. Therefore, a supporter will have six short breaks (of three to five days) between consecutive matches in addition to two longer ones, immediately before and after the tournament, during which they can plan some touris- tic trips. We study the problem faced by a touristic trip provider who wants …
Memristors and nonequilibrium stochastic multistable systems
2022
The main aim of this special issue is to report the recent advances and new trends in memristors and nonequilibrium stochastic multistable systems, both theoretically and experimentally, within an interdisci-plinary context. In particular, memristors are multistable systems whose switching dynamics is a stochastic process, which can be controlled by internal and external noise sources, unveiling the constructive role of random fluctuations. Furthermore, the use of memristors as memory elements in neuromorphic systems with noise-assisted persistence of memory states, chaotic dynamics, metastable chaos and chaos synchronization, new stochastic nonlinear models, noise-induced phenomena such as…

2022
The Madonie district, one of the 72 pilot areas of the National Strategy for Inner Areas in Italy in the center of Sicily, is composed by 21 municipalities that really have a great potential, due to their historical background and natural landscape, but it needs new strategies to emerge. Many people from northern cities have returned to their home villages in recent years, to live and work, but they have not found some important and necessary services as there are in smart cities, and to date, these villages do not adopt smart strategies. Many changes need to be made, one solution is to transform them into smart villages through rehabilitation, such as improving the historic center with str…

Evaluation of crack-closure by second harmonic thermoelastic stress analysis
2022
The work illustrates a new experimental approach to evaluate crack-closure in samples undergoing Fatigue Crack-Growing. Crack-closure leaves a peculiar signature on both amplitude and phase of the harmonic of the temperature signal at twice the loading frequency (Second Harmonic), due to the periodic nature of the internal elastic compression stresses. Thermoelastic Stress Analysis (TSA) is successfully applied to reveal such signatures on Single-Edge-Notched steel samples. A methodology is also proposed to evaluate the Crack-Opening-Load from temperature data. The work finally explores the influence of crack-closure on crack-tip identification and on the evaluation of the Stress Intensity …

Prospezione speleoarcheologica della falesia «Piana di Sopra» a San Vito lo Capo (TP)
2022
The northern coast of Trapani is characteristed by a series of phenomena linked to Quaternary glaciations. These phenomena have modeled esplanades, terraces, cliffs, leaf grooves and caves of great natural beuaty. The extreme strip of the Peninsula of S. Vito lo Capo, the Piana di Sopra, is made up of parareciphal limestones with Orbitoline and Rudist from the Cretaceous. This area has a strong density of cavities of marine origin estimated at four cavities per kilometer. These cavities are an important anthropological testimonly to a continual human presence from deep prehistory onwards. A fundamental prerequisite for a study of the prehistory of an area is its geomorphologic description w…

Minimal Dose of Resistance Exercise Required to Induce Immediate Hypotension Effect in Older Adults with Hypertension:Randomized Cross-Over Controlle…
2022
To determine the optimal exercise volume to generate a hypotension response after the execution of a single strength exercise in elderly subjects with hypertension (HT), a randomized crossover design was performed. A total of 19 elderly subjects with HT performed one control session and three experimental sessions of resistance training with different volumes in a randomized order: three, six, and nine sets of 20 repetitions maximum (RM) of a single elbow flexion exercise with elastic bands. The systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean heart rate (MHR) were tested at the beginning and immediately afterwards, at 30 and 60 min, and at 4, 5, and 6 h after the res…

A Short Review of Simple Analytical Methods for the Evaluation of PAHs and PAEs as Indoor Pollutants in House Dust Samples
2022
Studies on indoor air quality are indispensable when considering that people spend approximately 85% of their time in confined environments. This short review mostly takes into consideration research that uses passive samplers to evaluate the quality of indoor environments (houses, school, cars, etc.). This short review summarizes most analytical methods to detect and quantify PAHs and PAEs in house dust used as a passive sampler. The objective of house dust analysis is to identify the presence, amount and distribution of specific hazardous substances in confined spaces and, if possible, to identify their sources. Household dust and the compounds present in it can enter the human body by in…
DEVELOPING AN INTEGRATED FRAMEWORK FOR ANALYZING WAYS OF REASONING IN MATHEMATICS
2022
Mathematics education literature involves studies that sought a way of investigating the mode of reasoning in mathematics textbooks because textbooks are the main resource for teachers in planning their mathematics lessons. In this vein, this study aimed to analyze the ways of reasoning in mathematics textbooks that are currently used in five countries: Slovakia, Czech Republic, Italy, Norway, and Turkiye, as a part of a Horizon 2020 Project. We initially started with a framework that aimed to examine the effect of teachers’ participation in the lesson study on the improvement of students’ mathematical reasoning (Project LESSAM). However, as the textbook analysis of different countries proc…
Sing and Measure: Sound as Voice as Quanta
2022
The universal concept of a “music of the spheres” traverses the history of philosophy, science and art, from Pythagoras to Kepler and beyond. In modern times, a sphere in three dimensions—the Bloch sphere—is used to illustrate the state of a qubit, the basic unit of quantum information. On the same spherical surface, the fundamental components of voice production can be located, so that any utterance can be seen as the evolution of a unit two-dimensional vector having complex coefficients. Indeed, any sound can be analyzed and decomposed into overlapping sinusoidal components, broadband noises, and impulsive transients, which in turn can be associated to fundamental means of vocal sound pro…
