Students' school‐level symptoms mediate the relationship between a school's observed moisture problems and students’ subjective perceptions of indoor…
2020
Moisture damage can influence the subjective assessment of indoor air quality (subjective IAQ) in various ways. We studied whether the frequency of symptoms reported across students at school level mediates the relationship between observed mold and dampness in a school building and students' subjective IAQ. To answer this research question, we tested a multilevel path model. The analyzed data were created by merging two nationwide data sets: (a) survey data from students, including information on subjective IAQ (N = 24,786 students); (b) data from schools, including information on mold and dampness in a school building (N = 222). After the background variables were adjusted, schools' obser…

Data Compensation with Gaussian Processes Regression: Application in Smart Building's Sensor Network
2022
Data play an essential role in the optimal control of smart buildings’ operation, especially in building energy-management for the target of nearly zero buildings. The building monitoring system is in charge of collecting and managing building data. However, device imperfections and failures of the monitoring system are likely to produce low-quality data, such as data loss and inconsistent data, which then seriously affect the control quality of the buildings. This paper proposes a new approach based on Gaussian process regression for data-quality monitoring and sensor network data compensation in smart buildings. The proposed method is proven to effectively detect and compensate for low-qu…
A Numbers-Based Approach to a Free Particle's Spacetime
2020
A possibility is proposed to define the proper spacetime of a free nonzerorest- mass m_0 particle based on the connection of its lasting proper time to an open sequence of natural numbers counting de Broglie time periods (h/c^2)(m^(-1)_ 0 ) [see R. Ferber, A Missing Link: What is Behind de Broglie's" Periodic Phenomenon"?, Foundations of Physics Letters 9, 575 (1996)]. It is suggested to define a set of twodirectional intervals of the particle's proper space (proper distances) following the construction of positive and negative integers from the ordered pairs of the natural numbers, which belong to the sequence 1, 2, ..., n defining the elapsed interval of de Broglie time t_n. Corresponding…
Temporal Denoising of Kinect Depth Data
2012
The release of the Microsoft Kinect has attracted the attention of researchers in a variety of computer science domains. Even though this device is still relatively new, its recent applications have shown some promising results in terms of replacing current conventional methods like the stereo-camera for robotics navigation, multi-camera system for motion detection and laser scanner for 3D reconstruction. While most work around the Kinect is on how to take full advantage of its capabilities, so far only a few studies have been carried out on the limitations of this device and fewer that provide solutions to enhance the precision of its measurements. In this paper, we review and analyse curr…
Howard S. Becker e gli “approcci moderni” nello studio dei problemi sociali
2018
The article discusses the intellectual biography of sociologist Howard S. Becker taking into account his contribution to the sociological study of social problems. Becker believes in the possibility of an objective study of the properties of social problems. However he admits that the objective properties of a phenomenon are neither sufficient nor necessary to define something as a “social problem”.
Inter- and Intraobserver Variation in the Assessment of Preoperative Colostograms in Male Anorectal Malformations: An ARM-Net Consortium Survey
2020
Aim:Male patients with anorectal malformations (ARM) are classified according to presence and level of the recto-urinary fistula. This is traditionally established by a preoperative high-pressure distal colostogram that may be variably interpreted by different surgeons. The aim of this study was to evaluate the inter- and intraobserver variation in the assessment by pediatric surgeons of preoperative colostograms with respect to the level of the recto-urinary fistula. Materials and Methods:Sixteen pediatric surgeons from 14 European centers belonging to the ARM-Net Consortium twice scored 130 images of distal colostograms taken in sagittal projection at a median age of 66 days of life (rang…
Tensions and striving for coherence in an academic’s professional identity work
2017
The emergence of ‘new managerialism’ in academic institutions and professions has given rise to tensions between one’s professional self and work context. Such tensions often originate from a misalignment between institutional and personal values. This study builds on a dialogical approach to identity and discusses the role of inner tensions and conflicts in terms of making sense of one’s professional identity. These aspects are explored and exemplified by introducing a sample case of one individual student and university researcher/teacher, Anna, who participated in one-year Pedagogical Studies for Adult Educators. Leaning on the narratives of Anna’s learning diaries and a later interview,…
The Supremacy of the Constructivist Approach in the Field of Physics Education: Myths and Real Challenges
2012
We intend, first of all, to show that the supposed 'supremacy of the constructivist epistemology' in the field of physics teaching is just a myth that hides the actual supremacy of the ineffective transmission/reception model. We then centre our analyses and proposals on the real challenges to improve students' learning and attitudes. Résumé Nous essayons de montrer que la prétendue « suprématie de l'épistémologie constructiviste » dans le domaine de la didactique de la physique n'est qu'un mythe, qui cache la suprématie effective du modèle inefficace de la transmission/réception. Nous centrons ensuite nos analyses et propositions sur les défis réels pour améliorer l'apprentissage et les at…
Metodi digitali per l'insegnamento classico e umanistico
2020
Il volume propone una riflessione critica di carattere metodologico su alcuni strumenti e tecniche digitali per l'insegnamento scolastico ed universitario in ambito umanistico, con un'attenzione particolare alla didattica delle lingue, letterature e culture classiche. Per ciascuno strumento digitale, si valuta se esso comporti un effettivo miglioramento dal punto di vista dei metodi, alla luce di alcuni obiettivi e principi educativi generali: sono presentate e discusse solo innovazioni digitali che, in chiave costruttivista, rendano l'apprendimento più attivo, più critico, più creativo e più orientato verso un contributo positivo alla società. Una serie di proposte didattiche accompagna la…
