High Frequency Data Acquisition System for Modelling the Impact of Visitors on the Thermo-Hygrometric Conditions of Archaeological Sites: A Casa di D…
2018
[EN] The characterization of the microclimatic conditions is fundamental for the preventive conservation of archaeological sites. In this context, the identification of the factors that influence the thermo-hygrometric equilibrium is key to determine the causes of cultural heritage deterioration. In this work, a characterization of the thermo-hygrometric conditions of Casa di Diana (Ostia Antica, Italy) is carried out analyzing the data of temperature and relative humidity recorded by a system of sensors with high monitoring frequency. Sensors are installed in parallel, calibrated and synchronized with a microcontroller. A data set of 793,620 data, arranged in a matrix with 66,135 rows and …
The Predictors of Literacy Skills among Monolingual and Bilingual Finnish–Swedish Children During First Grade
2021
The aim of the study was to examine which predictor variables are related to literacy skills among monolingual Swedish (n = 269) and bilingual Finnish–Swedish (n = 229) children at the first grade in the Swedish-speaking schools in Finland. The participants were assessed in phonological awareness, letter knowledge, rapid automatized naming (RAN), word recognition, reading fluency, and spelling. The results showed that RAN was the most significant predictor of reading and spelling skills in both language groups, and monolingual children performed significantly better in RAN. Moreover, letter knowledge predicted reading and spelling skills in both groups. However, no significant differences b…
Income and Physical Activity among Adults: Evidence from Self-Reported and Pedometer-Based Physical Activity Measurements
2015
This study examined the relationship between income and physical activity by using three measures to illustrate daily physical activity: the self-reported physical activity index for leisure-time physical activity, pedometer-based total steps for overall daily physical activity, and pedometer-based aerobic steps that reflect continuous steps for more than 10 min at a time. The study population consisted of 753 adults from Finland (mean age 41.7 years; 64% women) who participated in 2011 in the follow-up of the ongoing Young Finns study. Ordinary least squares models were used to evaluate the associations between income and physical activity. The consistency of the results was explored by us…
Is personality related to permanent earnings? Evidence using a twin design
2018
Using twin survey combined with register-based panel data on labor market outcomes, the authors examine the association between personality characteristics and long-term earnings among prime working-age individuals. The long-term earnings were measured over the 1990–2008 period. The sample contains 4,642 twin pairs, of which 53% are females. In contrast to previous studies, this paper uses the within-twin dimension of the data to control for shared family background and confounding genetic factors. The results suggest that unobserved genetic differences may introduce omitted variable bias in standard ordinary least square results. After controlling for shared environment and genetic backgro…
Constant sign and nodal solutions for parametric anisotropic $(p, 2)$-equations
2021
We consider an anisotropic ▫$(p, 2)$▫-equation, with a parametric and superlinear reaction term.Weshow that for all small values of the parameter the problem has at least five nontrivial smooth solutions, four with constant sign and the fifth nodal (sign-changing). The proofs use tools from critical point theory, truncation and comparison techniques, and critical groups. Spletna objava: 9. 9. 2021. Abstract. Bibliografija: str. 1076.
Psychological processes of ACL-patients' post-surgery rehabilitation : A prospective test of an integrated theoretical model
2020
Objectives: The aim of this prospective study was to examine the utility of an integrated model comprising constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) in predicting adherence to a post-surgery rehabilitation program in patients receiving anterior cruciate ligament (ACL) reconstruction. Constructs of the integrated model measured at baseline were expected to predict patients' rehabilitation adherence two months later. Method: Patients (N = 121, M age = 27.62, range = 18–53; 36.66% female) scheduled to have ACL reconstruction surgery within two months were recruited from a Hong Kong public hospital. At baseline and two-month follow-up, patients com…
A New Reliable Performance Analysis Template for Quantifying Action Variables in Elite Men’s Wheelchair Basketball
2019
This study aimed to develop a valid and reliable performance analysis template for quantifying team action variables in elite men’s wheelchair basketball. First action variables and operational definitions were identified by the authors and verified by an expert panel of wheelchair basketball coaching staff in order to establish expert validity. A total of 109 action variable were then placed into 17 agreed Categorical Predictor Variable categories. The action variables were then used to develop a computerized performance analysis template for post-event analysis. Each possession (n = 200) from an international men’s wheelchair basketball game was analyzed by the first author on two occasio…
Progressive non-linear damage of variable angle tow composite plates by a Ritz approach
2022
In this work a Ritz model for progressive non-linear damage analysis of variable angle tow composite plates is presented. The damage is treated in the framework of continuum damage mechanics and its evolution is based on a linear softening law with which four damage indices are computed for degrading the mechanical properties of the material. A set of analyses have been carried out to investigate how damage evolves in VAT composite plates under progressive loading.
Estudio sobre la repercusión en la rotura de manguito de rotadores de las variables cardiometabólicas: glucosa, triglicéridos y colesterol
2016
A pesar de los importantes avances médicos llevadas a cabo en el campo de las tendinopatías durante las últimas décadas, aun no se conoce a ciencia cierta algunos aspectos relacionados con la fisiopatología del tendón. Recientemente, se ha sugerido que determinados factores cardio-metabólicos (colesterol, trgiliceéridos, glucosa) pueden infuir en los procesos patológicos del tendón, especialmente en aquellos del miembro infeiror, como el tendón de Aquiles o el tendón rotuliano. Sin embargo, la evidencia actual sobre la repercusión de estos factores en tendones del miembro superior es todavía menor, lo que requiere de nuevas investigaciones al respecto. Por tanto, el objetivo de este estudio…
Análisis 3D de la aceleración en crol en el dominio temporal y frecuencial
2012
El Estudio hace un repaso a las metodologías usadas por diferentes autores en lo que respecta al análisis, tanto frecuencia como temporal del nado a crol. El estilo libre (nado en crol) en natación, al igual que el resto de estilos (braza, espalda, mariposa) poseen una determinada coordinación para realizarse correctamente según la reglamentación vigente (FINA, 2011). En este trabajo se pretende indagar en los movimientos que se realizan en el estilo crol, principalmente las aceleraciones y desaceleraciones que se producen durante la fase de nado en el cuerpo del nadador que afectan al rendimiento. Se podría definir el término Aceleración como "toda variación de velocidad con respecto al ti…
