Development of new methodologies and tools for physiological measurements of indoor thermal comfort and well-being in buildings
No full textThe quality of indoor environments significantly affects occupants' well-being, with thermal conditions playing a vital role in health, work efficiency, and energy consumption. Traditional thermal comfort models rely on steady-state assumptions, failing to account for dynamic physiological responses to environmental changes. To address this gap, recent research has focused on developing Personal Comfort Models (PCMs) based on physiological data from wearable sensors.
This thesis explores the application of wearable devices in multidomain comfort. By integrating physiological measurements and Machine Learning (ML), the research aims to advance PCM development. It also evaluates the effects of thermal discomfort in warm environments on work productivity, providing scientific evidence for the benefits of PCM adoption.
The measurement chain includes physiological signals: Electroencephalogram (EEG), Heart Rate Variability (HRV), Electrodermal activity (EDA), and Skin Temperature (ST). Those signals were acquired via wearable devices, Interaxon MUSE, and Empatica e4. Experimental campaigns were conducted in NEXT.ROOM, a controlled environment. For each domain of investigation, appropriate protocols were followed, specifically fifty-two participants were exposed to three temperature settings (cold: 18°C ± 0.4, neutral: 25°C ± 0.2, warm: 32°C ± 0.5), while 24 participants underwent sessions combining temperature and lighting (Neutral: 4114 K, Red: 2010 K, blue Blue 178,000 K), resulting in a total of 416 tests. Physiological data were collected for 5 min after the acclimation period. Thirty-six participants were exposed to three different audio signals while EEG data was continuously recorded for 6 min in the test session. The data were pre-processed to eliminate artifacts, and customs procedures were employed for feature extraction. The identified features were used to create the PCM based on ML, and the uncertainty analysis of the wearable devices was applied to the measurement chain.
The findings show significant physiological differences across thermal conditions, with Beta TP10, Gamma TP10, cvsd, and Tonic Perc25 demonstrating p-values < 0.05 in the contrast cold vs warm conditions. In neutral light conditions, the results showed higher EEG Approximate Entropy (ApEn) values in the temporoparietal region compared to blue (p = 0.000009) and red (p = 0.000011). In the acoustic domain, increased delta and theta activity was recorded during exposure to annoying stimuli (p < 0.001), while alpha waves rose with pleasant sounds (H-statistic = 11.1, p < 0.001). These results indicate that wearable EEG devices provide valuable insights into visual and acoustic perceptions.
The study further examined the relationship between physiological parameters and thermal sensation (TS), testing various ML algorithms. The results of the uncertainty analysis revealed that Random Forest achieved an accuracy of 86 ± 0.04%. Additionally, it explored the impact of thermal comfort on cognitive and motor performance, revealing that participants in warmer environments had slower initiation times (F(1, 81) = 4.777, p = 0.032, η2 = 0.056) but maintained accuracy, indicating a compensatory mechanism for cognitive strain.
In conclusion, this thesis highlights the importance of integrating wearable technologies with PCMs for real-time monitoring of thermal comfort. Adjusting environmental conditions based on physiological responses can enhance individual well-being and improve energy efficiency in buildings
Changes and New Religious Orientations Among Practicing Catholics?
No full textThis essay takes its cue from a re-examination of a previous research report. In particular, this paper aims to present some additional reflections, which have also been shaped by discussions with recent research on lived religiosity. The 2017 study involved 2675 individuals of Catholic faith who completed a detailed questionnaire, representing
an opportunistic sample, and another 372 people who formed the comparison group. The objective was to investigate the languages, forms, and structures of religious experience and religiosity. In this new interpretation, we instead focus on those elements of the 2017 study that suggest new shared attitudes or possible historical transformations of religiosity among the subjects initially consulted
Gli ultimi forzati delle galere del papa. Il viaggio da Civitavecchia a Malta nel 1797
No full textIl presente contributo analizza un episodio finora marginale nella storiografia sulla schiavitù mediterranea: il trasferimento di forzati appartenenti allo Stato pontificio da Civitavecchia a Malta nel 1797, un anno prima dell’abbandono dell’arcipelago da parte dell’Ordine di San Giovanni e del suo trasferimento alla Repubblica francese. La corrispondenza presa in esame, tra l’inquisitore Giulio Carpegna e la Segreteria di Stato pontificia, consente di ricostruire il destino dell’ultimo carico di forzati a vita del papa inviato a Malta. Il contributo chiarisce anche le peculiarità della schiavitù atlantica e di quella mediterranea, mettendo in luce le specificità della seconda - caratterizzata da reciprocità, temporaneità e reversibilità - e il suo radicamento nelle logiche politico-religiose della guerra di corsa

No full textA Mountain of Content. An Early Look at Paramount+ and Its Strategies
No full textLaunched in the first territories in September 2021 and turned into a global portal in the following year, Paramount+ is the evolution of CBS All Access into a modern streaming portal. Paramount+ model results in a vertical integration by an IP-holding corporation in the direction of on-demand distribution, through a proprietary channel that allows it to have full control over products. Carrying a disparate constellation of brands, Paramount+ showcases an array of intellectual properties that digs into a vast legacy ground. In this, Paramount+ has so far operated, for its original
contents and placement strategies that are still far from solid, reflecting the still quite acerbic functional nature of the portal itself. This paper examines Paramount+ early attempts at original content branding and its experimental transmedia expansion of IP; therefore, it aims to return a discursive picture of the direction the portal is taking via its content portfolios, assessing the effects of successes and failures. Due to territorialization reasons, the
analysis of positioning is here carried out in the Italian context: this limitation becomes an opportunity for an initial assessment of the glocal dimension of the portal and to discuss the relationship between Paramount+ and

Effect of the Rovatti Method® (Physiotherapeutic Scoliosis-Specific Exercises) in an Adolescent Patient with Idiopathic Scoliosis: A Case Report
No full textBackground and Clinical Significance: The study aims to investigate the application of the Rovatti Method® in improving Cobb angles, angle of trunk rotation (ATR), aesthetics, and quality of life in the conservative treatment of adolescent idiopathic scoliosis (AIS); Case Presentation: The case concerns the application of the Rovatti Method® in treating a 13-year-old girl with mild right thoracolumbar AIS. This method involves the use of elastic bands designed to guide and enhance proprioceptive and mechanical stimuli during the patient’s active self-correction exercises. The treatment lasted 7 months; A a radiographic control showed an improvement in the right thoracolumbar curve, with Cobb angles decreasing from 21° to 14°, ATR from 10° to 8°, TRACE (Trunk Aesthetic Clinical Evaluation) decreasing from 8 to 4 points, and the Scoliosis Research question-naire (SRS- 22) improving from 2.27 to 3.05 points.; Conclusions: Concerning this hy-pothesis-generating observation case, the Rovatti Method® may represent a kinesiological approach for the treatment of AIS, potentially contributing to improvements in Cobb angles, ATR, aesthetics, and quality of life
