Multi-variate analysis predicts clinical outcome 30 days after middle cerebral artery infarction
2000
BACKGROUND AND PURPOSE: To evaluate the functional prognostic value of proton magnetic resonance spectroscopy performed within the 5 days of an infarction of the middle cerebral artery territory, compared with previously demonstrated prognostic factors. METHODS: Proton magnetic resonance spectroscopy was performed on 77 consecutive non-comatosed patients during the acute stage of middle cerebral artery infarction. The functional status was determined for each patient via the Orgogozo score. Proton magnetic resonance spectroscopic data were acquired in the infarction and in contra-lateral normal tissue and the results were expressed as metabolite ratios. Correlations were evaluated between t…
Diferenças de sexo no uso de estratégias de enfrentamento em pessoas com lesão medular
2017
12 Páginas Objetivo: profundizar en la experiencia de afrontamiento en personas con lesión medular (LM), teniendo en cuenta tanto el afron- tamiento actual como el afrontamiento durante momentos iniciales tras sufrir la LM. Materiales y métodos: estudio transversal de encuesta. Participaron 127 personas con LM de larga evolución, 95 hombres y 32 mujeres. Los datos fueron recogidos por medio de un cuestionario online con información sociodemográfica y el Cuestionario de Afrontamiento del Estrés (CAE). Se han realizado análisis descriptivos, pruebas t de Student y análisis multivariados de la varianza (Manovas) Resultados: las comparaciones intrasujetos muestran que la estrategia de focalizac…
Autonomic Modulation Improves in Response to Harder Performances While Playing Wind Instruments
2020
Background: Despite inducing autonomic benefits similar to exercise, playing wind instruments is a physical, and cognitive task of high attentional requirements, which demands musicians maximal efforts, leading to sympathetic hyperarousal and autonomic worsening. In this context of controversy, it remains unknown the autonomic response to playing highly demanding music performances, as compared to an easier one, which might be of interest in wind musicians' cardiovascular health. Objectives: This study aimed to investigate differences in the autonomic control of the heart with regard to task demands (TD), avoiding emotional influences (rehearsal performance). Methods: Eight healthy male pro…
Housing market shocks in italy: A GVAR approach
2020
Abstract In this paper, we use a Global Vector Autoregression (GVAR) model to assess the spatio-temporal mechanism of house price spillovers, also known as “ripple effect”, among 93 Italian provincial housing markets, over the period 2004 − 2016 . In order to better capture the local housing market dynamics, we use data not only on house prices but also on transaction volumes. In particular, we focus on estimating, to what extent, exogenous shocks, interpreted as negative housing demand shocks, arising from 10 Italian regional capitals, impact on their house prices and sales and how these shocks spill over to neighbours housing markets. The negative housing market demand shock hitting the G…
Molecular characterisation of k-casein gene in Girgentana dairy goat breed and identification of two new alleles
2015
The k-casein fraction plays an important role in the formation, stabilisation and aggregation on casein micelles and thus affects technological and nutritional properties of milk. In this study, exon 4 of k-casein (CSN3) gene was sequenced and analysed in Girgentana goat breed. Analyses of the obtained sequences showed the presence of A, B, D, and G known alleles and two new genetic variants, named D’ and N. The new D’ allele differs from D in one transition, G284→A284, which did not cause amino acid change. The new N allele differs from A in five single nucleotide polymorphisms (SNPs): T245/C245, G284/A284, G309/A309, G471/A471 and T591/C591, while it differs from C in one transition, i.e.…
Assessing Teacher’s Discourse Effect on Students’ Learning: A Keyword Centrality Approach
2020
The way that content-related keywords co-occur along a lesson seems to play an important role in concept understanding and, therefore, in students’ performance. Thus, network-like structures have been used to represent and summarize conceptual knowledge, particularly in science areas. Previous work has automated the process of producing concept networks, computed different properties of these networks, and studied the correlation of these properties with students’ achievement. This work presents an automated analysis of teachers’ concept graphs, the distribution of relevance amongst content-related keywords and how this affects students’ achievement. Particularly, we automatically extracted…
Is «Social language variation» an operational category for language corpus planning?
2019
Hem constatat les dificultats d’aprofundir les relacions conceptuals entre la variació social i la funcional, que comencen quan ens preguntem quins factors socials són pertinents per descriure el col·loquial. Creiem que cal tenir en compte, en ordre decreixent, les «adscripcions identitàries» que Block (2014) analitza: capital lingüístic, capital cultural, edat, gènere, activitat habitual, «habitus/ideologia/actituds», «classe social», ètnia i religió. En aquest context d’incertesa conceptual, no és estrany que la variació social sigui una dimensió sociolingüística tractada inadequadament en la normativa catalana: Badia (1994) confon els termes diastràtic i diafàsic i llegint els textos nor…
SLFTD: A Subjective Logic Based Framework for Truth Discovery
2019
Finding truth from various conflicting candidate values provided by different data sources is called truth discovery, which is of vital importance in data integration. Several algorithms have been proposed in this area, which usually have similar procedure: iteratively inferring the truth and provider’s reliability on providing truth until converge. Therefore, an accurate provider’s reliability evaluation is essential. However, no work pays attention to “how reliable this provider continuously providing truth”. Therefore, we introduce subjective logic, which can record both (1) the provider’s reliability of generating truth, and (2) reliability of provider continuously doing so. Our propose…
Effects of stress on chewing and food intake in patients with anorexia nervosa
2021
OBJECTIVE The present study investigates the impact of psychosocial stress on chewing and eating behavior in patients with anorexia nervosa (PAN ). METHOD The eating and chewing behavior of PAN were examined in a standardized setting by means of a chewing sensor. These procedures encompassed n = 19 PAN , age, and gender matched to n = 19 healthy controls (HC). Food intake and chewing frequency were assessed in two experimental conditions: rest versus stress (via Trier Social Stress Test). To verify stress induction, two appraisal scales were employed. In addition, chronic stress, psychological distress and eating disorder symptoms were assessed. RESULTS In terms of food intake and chewing f…
Context Effects in the Evaluation of Bodily Symptoms: Comparing Three Versions of the Health Norms Sorting Task
2017
The illness-related evaluation of bodily symptoms is considered to be an important maintaining factor in somatoform disorders. However, little is known about context variables that could influence this evaluation process. In the current study, participants completed three versions of the Health Norms Sorting Task (HNST) and evaluated bodily symptoms in different contexts (i.e., different evaluation perspectives and time frames of evaluation). Additionally, the three HNST versions were presented in different orders. Bodily symptoms were evaluated more often as a sign of illness when a specific time frame (i.e., one week) was given. However, this context effect was only large when participan…
