The image of cruise ship holidays on Italian television: a comparative analysis.
2017
By conceptualizing the cruise ship as the destination in itself, this contribution discusses the role of destination image in cruise passengers' decision-making processes and focuses on the role and contents of visual texts such as TV commercials in the promotion of cruise tourism. A content analysis is performed over TV commercials broadcast by different cruise lines to Italian travellers. Specific components of the image of ships as tourist destinations as promoted through TV advertising campaigns are identified.
Automated scoring of teachers’ pedagogical content knowledge : a comparison between human and machine scoring
2020
To validly assess teachers’ pedagogical content knowledge (PCK), performance-based tasks with open-response formats are required. Automated scoring is considered an appropriate approach to reduce the resource-intensity of human scoring and to achieve more consistent scoring results than human raters. The focus is on the comparability of human and automated scoring of PCK for economics teachers. The answers of (prospective) teachers (N = 852) to six open-response tasks from a standardized and validated test were scored by two trained human raters and the engine “Educational SCoRIng Toolkit” (ESCRITO). The average agreement between human and computer ratings, κw = 0.66, suggests a convergent …
One and Two Dimensional Convolutional Neural Networks for Seizure Detection Using EEG Signals
2021
Deep learning for the automated detection of epileptic seizures has received much attention during recent years. In this work, one dimensional convolutional neural network (1D-CNN) and two dimensional convolutional neural network (2D-CNN) are simultaneously used on electroencephalogram (EEG) data for seizure detection. Firstly, using sliding windows without overlap on raw EEG to obtain the definite one-dimension time EEG segments (1D-T), and continuous wavelet transform (CWT) for 1D-T signals to obtain the two-dimension time-frequency representations (2D-TF). Then, 1D-CNN and 2D-CNN model architectures are used on 1D-T and 2D-TF signals for automatic classification, respectively. Finally, t…
A Cooperative Multi-Agent System for Crowd Sensing Based Estimation in Smart Cities
2020
The concept of Smart City has spread as a solution to ensure better access to information and services to citizens, but also as a means to reduce the environmental footprint of cities. To this end, a continuous and wide observation of the environment is necessary to analyze information that enables government bodies to act on the environment appropriately. Moreover, a diffused acquisition of information requires adequate infrastructure and proper devices, which results in relevant installation and maintenance costs. Our proposal enables reducing the number of necessary sensors to be deployed while ensuring that information is available at any time and anywhere. We present the HybridIoT syst…
StateOS : A Memory-Efficient Hybrid Operating System for IoT Devices
2023
The increasing significance of operating systems (OSs) in the development of the internet of things (IoT) has emerged in the last decade. An event-driven OS is memory efficient and suitable for resource-constrained IoT devices and wireless sensors, although the program’s control flow, which is determined by events, is not always obvious. A multithreaded OS with sequential control flow is often considered clearer. However, this approach is memory-consuming. A hybrid OS seeks to combine the strengths of the event-driven approach with multithreaded approach. An event-driven cooperative threaded OS represents a hybrid approach that supports concurrency by explicitly yielding control to another …
«Corpi normali, corpi devianti». Sessualità, razza e abilità nella costruzione dei modelli corporei normativi
2018
Il capitolo analizza le modalità attraverso le quali la produzione di conoscenze e saperi specifici contribuisce a definire corpi ideali e, pertanto, normativi. Attraverso la riflessione sociologica sulla «razza», il genere e la sessualità nonché l’abilità corporea si intende fornire strumenti per comprendere in che modo le società producono «corpi normali» e «corpi devianti» e su quali assetti ideologici si fonda la suddetta distinzione.
Il corpo «straniero» nei contesti formativi e lavorativi della nostra società
2021
In ogni epoca storica, l’umanità è stata segnata da processi migratori. Sui migranti, sappiamo oramai che sono uomini e donne, adulti e bambini che, liberamente o sotto costrizione, lasciano, da soli o in gruppo, il proprio Paese di origine al fine di trovare altrove una nuova stabilità fisica, lavorativa, economica e soprattutto identitaria. Fin dalle origini della storia dell’uomo, tutte le migrazioni sono state sempre segnate da due aspetti fondamentali che riguardano lo spazio e il tempo. All’interno di questo capitolo si sviluppa una riflessione sulla rappresentazione collettiva del corpo in termini anche di spazio politico, cioè un corpo in movimento, quello di colui o colei che si tr…
Probing the origin of ultra-high-energy cosmic rays with neutrinos in the EeV energy range using the Pierre Auger Observatory
2019
Neutrinos with energies above 1017 eV are detectable with the Surface Detector Array of the Pierre Auger Observatory. The identification is efficiently performed for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for Earth-skimming τ neutrinos with nearly tangential trajectories relative to the Earth. No neutrino candidates were found in ∼ 14.7 years of data taken up to 31 August 2018. This leads to restrictive upper bounds on their flux. The 90% C.L. single-flavor limit to the diffuse flux of ultra-high-energy neutrinos with an Eν -2 spectrum in the energy range 1.0 × 1017 eV -2.5 × 1019 eV is E2 dNν/dEν < 4.4 × 10-9 GeV cm-2 s-1 sr-1, placing str…

Urban Growth and Real Estate Income. A Comparison of Analytical Models
2016
I processi di crescita urbana sono notoriamente complessi dipendendo da un’ampia varietà di fattori demografici, socio-culturali ed economici. L’analisi è ancora più complessa nelle aree metropolitane che sono il risultato di antichi processi di agglomerazione in una fase d’intenso accrescimento dell’insediamento e, più recentemente, della formazione di policentrismo urbano. L’investigazione richiede l’acquisizione, l’analisi e l’elaborazione d’idonee informazioni a livello delle unità territoriali omogenee, basandosi su modelli consolidati o su nuovi protocolli da verificare. Il presente contributo analizza la crescita urbana secondo un approccio di piccola scala, individuando i distretti …
