Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation
2019
In this article, the synthesis by means of the spray pyrolysis method, of the CaMoO4 and rare-earth cation (RE3+)-doped CaMoO4:xRE3+ (RE3+ = Eu3+, Tb3+, and Tm3+; and x = 1, 2, and 4% mol) compounds, is presented. The as-synthesized samples were characterized using X-ray diffraction, Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first-principles calculations, at the density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energie…
Ethical underpinnings for the development of health literacy in schools : ethical premises (‘why’), orientations (‘what’) and tone (‘how’)
2018
Background Schools are seen as crucial environments to influence and develop the health literacy of new generations, but without sufficient reflection on the ethical underpinnings of intentions and interventions around health literacy. In contrast, we argue here that ethics are fundamental to all education. The article adopts a ‘One world’ approach that generalizes broadly across the so-called Global North and Global South. It also generalizes across various age groups among school pupils, advocating age appropriate application of the arguments advanced. Main text Our analysis examines why health literacy should be promoted in schools and argues that the purpose should embrace the values of…
Ohjaajien toiminta elintapamuutosten tukemisessa tyypin 2 diabeteksen ehkäisyn ryhmäohjauksessa
2016
The purpose of the study was to describe the supervisors’ action in the support of changing one’s living habits in two weight management groups in the type 2 diabetes prevention program. The data consists of 17 video-recorded 90-minute “Small decision a day” weight management group counselling sessions of two groups with 10 and 20 participants in the years 2004-2005. The supervisors’ talk was analyzed with the deductive analysis from five teaching perspectives including theirs beliefs, intentions and actions. The transtheoretical change model and the participants’ talk were analyzed with the inductive analysis. Quantitative methods were used to give more information about the counselling se…
Longitudinal and cross-sectional associations of adherence to 24-hour movement guidelines with cardiometabolic risk
2022
This study aimed to examine 1) adherence to 24-hour movement guidelines over a 2-year follow-up in children aged 6-8 years and 2) association of this adherence with cardiometabolic risk factors. Physical activity and sleep were assessed by a monitor combining heart rate and accelerometry measurements. Screen time was reported by the parents. Body fat percentage, waist circumference, blood glucose, serum insulin, plasma lipids and blood pressure were assessed, and a cardiometabolic risk score was calculated using z-scores. Children were classified as meeting the guidelines if they had on average ≥60min/day of moderate-to-vigorous physical activity during the valid days; ≤120min/day of screen…
The 2D:4D ratio and its relationship with other androgenisation parameters in parents of individuals with autism spectrum disorders.
2013
The 2D:4D ratio is the quotient between the index and ring fin-ger lengths and is a non-direct indicator of androgenisation. If prenatal tes-tosterone levels in the amniotic fluid are high then the probability increases of developing lower ratio values. It has been suggested that people with au-tism spectrum disorders (ASD) and their parents may have highly andro-genised brains, and for this reason the 2D:4D ratio is used as a marker of such idiosyncrasies. This study aims to analyse if parents of people with ASD differ from the general population in several parameters of andro-genisation related to the 2D:4D ratio. The sample was composed of 43 parents of offspring with ASD and 42 controls…
A Particular Focus on the Prevalence of α- and β-Thalassemia in Western Sicilian Population from Trapani Province in the COVID-19 Era
2023
Thalassemia is a Mendelian inherited blood disease caused by α- and β-globin gene mutations, known as one of the major health problems of Mediterranean populations. Here, we examined the distribution of α- and β-globin gene defects in the Trapani province population. A total of 2,401 individuals from Trapani province were enrolled from January 2007 to December 2021, and routine methodologies were used for detecting the α- and β-globin genic variants. Appropriate analysis was also performed. Eight mutations in the α globin gene showed the highest frequency in the sample studied; three of these genetic variants represented the 94% of the total α-th…
E-Sports y brecha de género: la percepción de las profesionales españolas
2019
The present paper aims to identify the causes of under-representation of women in E-sports. According to a genre perspective, interest in videogames at the amateur level is quite similar. However, in its professional level, female participation becomes very limited. The fact that physical effort is irrelevant (a requirement for ?traditional sports?) could be considered a variable that would negatively affect greater to equality in the conditions of access and participation of women in electronic sports. Against any predictions, the data on the presence of women are elocuent: few women, with much lower wages than men to remunerate same skills, and a general complaint by the female profession…
Circumstances of the rise of the so-called Islamic State according to Patrick Cockburn’s perspective
2018
The aim of this article is to analyze the rise of the so-called Islamic State in the perspective of a Middle Eastern and commentator for “The Independent”, Patrick Cockburn, who also publishes in the “London Review of Books. The text begins with a sketch of the geopolitical determinants for the spread of the Islamic holy war, i.e. jihad. Then, it focuses on the disturbing phenomenon of sectarianism – directed mainly at the Shia branch of Islam – the attitudes of extremist Sunni preachers. The third chapter presents the complex combination of events that has contributed to the growth of extremist tendencies in Iraq. The subject of further deliberations is the conversion of the initially secu…
Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
Pressure-Dependent Tuning of Photoluminescence and Size Distribution of Carbon Nanodots for Theranostic Anticancer Applications
2020
Carbon nanodots (CDs) have recently attracted attention in the field of nanomedicine because of the biocompatibility, cost-effective nature, high specific surface, good near infrared (NIR) photothermal conversion into heat and tunable fluorescence properties, which have paved the way toward incorporating use of CDs into innovative anticancer theranostic platforms. However, a reliable synthesis of CDs with established and controlled physiochemical proprieties is precluded owing to the lack of full manipulation of thermodynamic parameters during the synthesis, thus limiting their use in real world medical applications. Herein, we developed a robust solvothermal protocol which allow fine contr…
