First measurement of the Sivers asymmetry for gluons using SIDIS data
2017
The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. It was extracted from measurements of the azimuthal asymmetry of hadrons produced in semi-inclusive deep inelastic scattering of leptons off transversely polarised nucleon targets, and it turned out to be non-zero for quarks. In this letter the evaluation of the Sivers asymmetry for gluons in the same process is presented. The analysis method is based on a Monte Carlo simulation that includes three hard processes: photon-gluon fusion, QCD Compton scattering and leading-order virtual-photon absorption process. The Sivers asymmetries of the three processes are simul…
Parenthood and gender inequality : Population-based evidence on the child penalty in Finland
2019
This study presents evidence on the effect of parenthood on labor market outcomes in Finland. We use population-based data drawn from administrative registers and an event study design centered around the birth of the first child using the specification proposed in Kleven et al. (2019b). The study confirms that women encounter large short- and long-term child penalties in gross labor earnings and that penalties are associated with employment participation. Taxes and social security transfers considerably reduce the child penalty, which also varies by the number of children. peerReviewed
Four Career Stories from Doctoral Students to Doctoral Holders : Qualitative Longitudinal Examination
2023
Aims: Universities and their doctoral programs open a range of career opportunities for doctoral students and doctors. There is a need to problematize assumptions related to the construction of doctoral careers. This study addresses this need by examining the development of doctoral career paths and the factors influencing them from a qualitative longitudinal perspective. This study focuses on the narrative career stories of doctoral students and doctoral graduates from a temporal perspective and at the individual level.
 Study Design: The study was conducted as qualitative longitudinal research among Finnish doctoral students and later same persons as doctoral holders (N=9). The aim o…
Incidenza di sintomi e malattie respiratori nell’arco di 18 anni in un campione di popolazione generale
2016
Background: recenti evidenze scientifiche mostrano come la prevalenza di sintomi/malattie respiratori stia continuando ad aumentare nella popolazione generale. Pochi studi riportano dati sull’incidenza (INC). Obiettivo: valutare INC di sintomi/malattie respiratori e di fattori di rischio associati in una coorte di soggetti residenti a Pisa. Metodi: un campione di popolazione generale ha partecipato a due indagini trasversali condotte nel 1991-93 (basale) e nel 2009-11 (follow-up) (n=1107) tramite questionario standardizzato su stato di salute e fattori di rischio; un sotto-campione ha eseguito la spirometria. INC di sintomi/malattie respiratori è stata calcolata sul campione di soggetti sen…
Subclinical cardiovascular damage in patients with HCV cirrhosis before and after treatment with direct antiviral agents: a prospective study
2018
BACKGROUND Cirrhosis is associated with morpho-functional cardiovascular alterations. AIMS To detect early features of cardiovascular damage in HCV-compensated cirrhotic patients using myocardial deformation indices and carotid arterial stiffness, and, further, to evaluate their short-term behaviour after HCV eradication with direct antiviral agents (DAAs). METHODS Thirty-nine consecutive patients with HCV cirrhosis, without previous cardiovascular events, were studied and matched for age, gender and cardiovascular risk factors to 39 controls without liver or cardiovascular disease. Patients and controls underwent a baseline echocardiographic evaluation including global longitudinal strain …

High heart rate amplifies the risk of cardiovascular mortality associated with elevated uric acid.
2021
Abstract Aims Whether the association between uric acid (UA) and cardiovascular disease is influenced by some facilitating factors is unclear. The aim of this study was to investigate whether the risk of cardiovascular mortality (CVM) associated with elevated UA was modulated by the level of resting heart rate (HR). Methods and results Multivariable Cox analyses were made in 19 128 participants from the multicentre Uric acid Right for heArt Health study. During a median follow-up of 11.2 years, there were 1381 cases of CVM. In multivariable Cox models both UA and HR, either considered as continuous or categorical variables were independent predictors of CVM both improving risk discriminat…
Endofenotipos neurocognitivos potenciales para el trastorno bipolar: velocidad motora manual, memoria visual, velocidad de procesamiento
2017
Antecedentes: Son pocas las investigaciones que se centran en el estudio de las disfunciones neurocognitivas en pacientes con trastorno bipolar (TB) como posibles marcadores de rasgo para esta enfermedad, menos aún son las que comparan el rendimiento motor, la memoria visual o la velocidad de procesamiento de la información, en estudios transversales o longitudinales, incluyendo a la vez, controles (CS) y familiares sanos de primer grado de los pacientes (TB-F); hasta la redacción de esta tesis, aunque el número va en aumento, en la investigación psiquiátrica el trastorno bipolar sigue ocupando un lugar secundario frente a la esquizofrenia, siendo insuficientes los estudios que buscan evide…
Longitudinal Strain Analysis and Correlation with TIMI Frame Count in Patients with Ischemia with No Obstructive Coronary Artery (INOCA) and Microvas…
2023
Background: The aim of the study is to evaluate the subclinical alterations of cardiac mechanics detected using speckle-tracking echocardiography and compare these data with the coronary angiography indices used during coronary angiography in a population of patients diagnosed with ischemia with no obstructive coronary artery (INOCA) and microvascular angina (MVA). Methods: The study included 85 patients admitted to our center between November 2019 and January 2022 who were diagnosed with INOCA compared with a control group of 70 healthy patients. A collection of anamnestic data and a complete cardiovascular physical examination, and echocardiogram at rest with longitudinal strain were perf…
Dépenses d’enseignement dans les collèges privés et publics et indice de positionnement social : une analyse spatiale et longitudinale
2023
Introduction En France, depuis 1963, date d’instauration de la carte scolaire, l’affectation des élèves dans un collège est fonction de son lieu de résidence. Ainsi, chaque élève est affecté à un collège public à proximité de son domicile. Par essence, cette méthode d’affectation reproduit au sein des collèges la ségrégation résidentielle. La possibilité d’obtenir des dérogations à cette affectation administrative, l’assouplissement de la carte scolaire de 2007, et la liberté de scolariser so...
