Ramadan Exposure In Utero and Child Mortality in Burkina Faso: Analysis of a Population-Based Cohort Including 41,025 Children.
2017
Ramadan exposure in utero can be regarded as a natural experiment with which to study how nutritional conditions in utero influence susceptibility to disease later in life. We analyzed data from rural Burkina Faso on 41,025 children born between 1993 and 2012, of whom 25,093 were born to Muslim mothers. Ramadan exposure was assigned on the basis of overlap between Ramadan dates and gestation, creating 7 exclusive categories. We used proportional hazards regression with difference-in-differences analysis to estimate the association between Ramadan exposure at different gestational ages and mortality among children under 5 years of age. Under-5 mortality was 32 deaths per 1,000 child-years. U…
Adjuvant Imatinib in Patients with GIST Harboring Exon 9 KIT Mutations : Results from a Multi-institutional European Retrospective Study
2022
[Purpose] The effect of high-dose imatinib (800 mg/day) on survival in the adjuvant treatment of patients with resected KIT exon 9–mutated gastrointestinal stromal tumors (GIST) is not established. Here, the association of dose and other clinicopathologic variables with survival was evaluated in a large multi-institutional European cohort.
A high salivary calcium concentration is a protective factor for caries development during orthodontic treatment
2020
Background This research aimed to evaluate the salivary concentrations of fluoride (F-), calcium (Ca2+), and phosphate (Pi) after brackets bonding, and to identify the role of [F-], [Ca2+], and [Pi] on the development of active caries lesion (ACL) in individuals under fixed orthodontic treatment. Material and Methods A longitudinal investigation with twenty-two individuals from 11 to 22 years of age was performed in four phases (baseline and after 1, 3, and 6 months). Analyses were carried out considering the salivary concentration of [F-], [Ca2+], and [Pi], as well as the caries index. Data were analyzed using the Friedman test, followed by the Wilcoxon test and the multivariate Cox model …
Business Models and Economic Approaches for Recovering Energy from Wastewater and Fecal Sludge
2015
Universal access to water, sanitation and energy services are key challenges in low income countries. The conventional model of providing water, sanitation and waste disposal as a social service is no longer viable because national authorities lack financial and human resources for operation and maintenance and for addressing the sanitation needs locally. Human excreta and wastewater represent resources that can be used to generate new income and support livelihoods through use as a source of energy. The reduction, removal and reuse of wastes must become financially feasible and economically profitable and yield high returns. This requires innovative and sustainable business models and fina…

On Obtaining Classification Confidence, Ranked Predictions and AUC with Tsetlin Machines
2020
Tsetlin machines (TMs) are a promising approach to machine learning that uses Tsetlin Automata to produce patterns in propositional logic, leading to binary (hard) classifications. In many applications, however, one needs to know the confidence of classifications, e.g. to facilitate risk management. In this paper, we propose a novel scheme for measuring TM confidence based on the logistic function, calculated from the propositional logic patterns that match the input. We then use this scheme to trade off precision against recall, producing area under receiver operating characteristic curves (AUC) for TMs. Empirically, using four real-world datasets, we show that AUC is a more sensitive meas…
Teaching of energy issues: A debate proposal for a global reorientatiom
2007
The growing awareness of serious difficulties in the learning of energy issues has produced a great deal of research, most of which is focused on specific conceptual aspects. In our opinion, the difficulties pointed out in the literature are interrelated and connected to other aspects (conceptual as well as procedural and axiological), which are not sufficiently taken into account in previous research. This paper aims to carry out a global analysis in order to avoid the more limited approaches that deal only with individual aspects. From this global analysis we have outlined 24 propositions that are put forward for debate to lay the foundations for a profound reorientation of the teaching o…
Presentazione di Gesù al tempio. Proporzioni e composizione
2009
Lo studio individua i sistemi proporzionali e compositivi del quadrone in stucco raffigurante La presentazione di Gesù al tempio, situato nella chiesa di S. Spirito, realizzato da Giacomo Serpotta agli inizi del XVIII secolo; all’interno del quadrone si alternano sia figure a tuttotondo, sia altorilievi che bassorilievi. Oltre lo studio delle proporzioni si sono analizzati alcuni elementi della grammatica visiva come la composizione e lo spazio. La rappresentazione illusoria dello spazio - di cui Giacomo Serpotta era un interprete eccezionale - come infinita e molteplice continuità spaziale, nasce da una nuova concezione dello spazio maturata dalla crisi della cultura umanistica e rinascime…
Il lavoro culturale a scuola. Un metodo fenomenologico di formazione dell'intelligenza
2016
Una scuola buona, in ogni ordine e grado, ha il compito della promozione culturale. Qui tale compito viene inteso come educazione del pensare, ossia formazione dell'intelligenza e della ragione. La prima tesi sostenuta e argomentata nel testo è che la chiave di volta di quest'opera formativa è costituita dall'intelligenza, vista e intesa come capacità del soggetto di vedere. L'impegno maggiore del saggio è però nel presentare e interpretare la fenomenologia come una pratica di ricerca del senso costituita al fondo da un affinamento dell'intelligenza: nella scelta dei concetti adeguati per intendere il senso di una realtà; nella formulazione delle proposizione che riconosce la verità o la fa…
LEADING SECONDARY SCHOOL STUDENTS TO FACE THE DISCIPLINARY, EPISTEMOLOGICAL AND SOCIETAL CHALLENGES OF CLIMATE CHANGE: DESIGN AND ANALYSIS OF MULTI-D…
The scientific community has been debating climate change (CC) for over two decades. In the light of certain arguments put forward by the aforesaid community, the EU has recommended a set of innovative reforms to science teaching, such as incorporating environmental issues into the scientific curriculum, thereby helping to make schools a place of civic education. However, despite these European recommendations, relatively little emphasis is still given to climate change within science curricula. The main goal of the research project described in this thesis is to study if, how and why the scientific contents related to CC could be reconstructed so as to integrate the many dimensions involve…
