INDICADORES DE LA CALIDAD DEL PROCESO DE ACOGIMIENTO FAMILIAR
2016
Abstract:INDICATORS OF THE QUALITY OF THE FOSTER CAREOne of the difficulties in choosing the families who come to foster care is related to the lack of studies that indicate the features needed to support optimal integrated development of children in foster care and also help in the process both the family as the child to generate the necessary resources. The sample consisted of 53 families with 80 children in foster care for three years. The aim was to identify characteristics that allow promote the development of the child. The results underline the importance of establishing secure links between the child and the foster family, the integration of the child in the foster family (the emerg…
Conjunction of Conditional Events and t-Norms
2019
We study the relationship between a notion of conjunction among conditional events, introduced in recent papers, and the notion of Frank t-norm. By examining different cases, in the setting of coherence, we show each time that the conjunction coincides with a suitable Frank t-norm. In particular, the conjunction may coincide with the Product t-norm, the Minimum t-norm, and Lukasiewicz t-norm. We show by a counterexample, that the prevision assessments obtained by Lukasiewicz t-norm may be not coherent. Then, we give some conditions of coherence when using Lukasiewicz t-norm
An infinite family of counterexamples to a conjecture on positivity
2021
Recently, G. Mason has produced a counterexample of order 128 to a conjecture in conformal field theory and tensor category theory in [Ma]. Here we easily produce an infinite family of counterexamples, the smallest of which has order 72.
Self-reported dependence on mobile phones in young adults: A European cross-cultural empirical survey
2017
Background and aims: Despite many positive benefits, mobile phone use can be associated with harmful and detrimental behaviors. The aim of this study was twofold: to examine (a) cross-cultural patterns of perceived dependence on mobile phones in ten European countries, first, grouped in four different regions (North: Finland and UK; South: Spain and Italy; East: Hungary and Poland; West: France, Belgium, Germany, and Switzerland), and second by country, and (b) how socio-demographics, geographic differences, mobile phone usage patterns, and associated activities predicted this perceived dependence.\ud \ud Methods: A sample of 2,775 young adults (aged 18–29 years) were recruited in different…
Functional Data Analysis and Mixed Effect Models
2004
Panel studies in econometrics as well as longitudinal studies in biomedical applications provide data from a sample of individual units where each unit is observed repeatedly over time (age, etc.). In this context, mixed effect models are often applied to analyze the behavior of a response variable in dependence of a number of covariates. In some important applications it is necessary to assume that individual effects vary over time (age, etc.).
‘You play like a Woman!’ Effects of gender stereotype threat on Women's performance in physical and sport activities: A meta-analysis
2018
Abstract Objectives The purpose of this quantitative review was to provide an estimation of the effect of stereotype threat on women's performance in sport. Design This review employed a meta-analytic technique. Method a meta-analysis with random effects model was performed on 24 effects. Publication bias was tested through funnel plots and Egger's regression test. Results Findings show a symmetric distribution of effects, making it possible to conclude that no file-drawer problem affected the collected sample of effects. Aggregating the results of the reviewed studies, a medium effect of stereotype threat manipulation on women's sport performances emerged (d = 0.33). Collected studies were…
Determination of Fusarium mycotoxins enniatins, beauvericin and fusaproliferin in cereals and derived products from Tunisia
2011
Abstract In this study, 51 samples of cereals (wheat, Barley, maize and Sorghum) and by-products (mainly pasta and couscous) purchased from Tunisian supermarkets were examined for contamination with the emerging Fusarium mycotoxins: Enniatins ENs (EN A, EN A 1 , EN B and EN B 1 ), beauvericin (BEA) and fusaproliferin (FUS). The extraction of the samples was performed with methanol using an Ultra-turrax homogenizer. Mycotoxins were analyzed with a liquid chromatography (LC) coupled to a diode array detector (DAD). The frequencies of contamination of total samples with ENs were 96%. EN A 1 was the most common EN found with the highest prevalence of 92.1%, levels ranged between 11.1 and 480 mg…
Polish is quantitatively different on quartzite flakes used on different worked materials.
2020
Metrology has been successfully used in the last decade to quantify use-wear on stone tools. Such techniques have been mostly applied to fine-grained rocks (chert), while studies on coarse-grained raw materials have been relatively infrequent. In this study, confocal microscopy was employed to investigate polished surfaces on a coarse-grained lithology, quartzite. Wear originating from contact with five different worked materials were classified in a data-driven approach using machine learning. Two different classifiers, a decision tree and a support-vector machine, were used to assign the different textures to a worked material based on a selected number of parameters (Mean density of furr…
Opening the black box of accounting for Greenhouse Gas Emissions: The different views of institutional bodies and firms
2018
Abstract This paper highlights the current accounting approaches to greenhouse gas (GHG) emissions. In particular, it explores and critically discusses the treatment of emission rights (ER) under carbon trading schemes from two distinct angles. On the one hand, it reviews the domestic solutions adopted by accounting bodies and, on the other, it examines current practices followed by firms in the European Energy Exchange (EEX). Regarding the former group, there are substantial differences, which would suggest some potential difficulties in finding a common solution for the future. Not surprisingly, there is still a diversity of approaches with regard to how firms report ER. Although the most…
