Changes in Family Income around the Time of Birth of Children in Germany between 1985 and 2004
2010
Während der Verlauf und die Ursachen des Geburtenverhaltens intensiv erforscht wurden, sind die finanziellen Folgen einer Geburt empirisch kaum beachtet worden. Daher werden hier kurzfristige Wohlstandsveränderungen von Familien (hinsichtlich verfügbarem Haushaltseinkommen und Äquivalenzeinkommen) rund um die Geburt eines Kindes in längsschnittlicher Perspektive analysiert und auf ihre Ursachen untersucht. Zu diesem Zweck wurden die Daten des Sozio-oekonomischen Panels (1984-2005) mittels Fixed-Effekt-Panelregressionsmodellen analysiert. Als Ergebnis kann festgehalten werden, dass die finanziellen Folgen einer Geburt in den letzten Jahren deutlich gewachsen sind und vor allem das erste Kind…
A fast hierarchical dual boundary element method for three-dimensional elastodynamic crack problems
2010
In this work a fast solver for large-scale three-dimensional elastodynamic crack problems is presented, implemented, and tested. The dual boundary element method in the Laplace transform domain is used for the accurate dynamic analysis of cracked bodies. The fast solution procedure is based on the use of hierarchical matrices for the representation of the collocation matrix for each computed value of the Laplace parameter. An ACA (adaptive cross approximation) algorithm is used for the population of the low rank blocks and its performance at varying Laplace parameters is investigated. A preconditioned GMRES is used for the solution of the resulting algebraic system of equations. The precond…
A fast dual boundary element method for 3D anisotropic crack problems
2009
In the present paper a fast solver for dual boundary element analysis of 3D anisotropic crack problems is formulated, implemented and tested. The fast solver is based on the use of hierarchical matrices for the representation of the collocation matrix. The admissible low rank blocks are computed by adaptive cross approximation (ACA). The performance of ACA against the accuracy of the adopted computational scheme for the evaluation of the anisotropic kernels is investigated, focusing on the balance between the kernel representation accuracy and the accuracy required for ACA. The system solution is computed by a preconditioned GMRES and the preconditioner is built exploiting the hierarchical …
Individual characteristics associated with fat liking
2015
Introduction: Various studies have shown that sensory liking influences dietary behaviors and that individual characteristics, such as socio-demographic or psychological factors, are related to dietary intake and weight status. However, little is known about individual profiles associated with fat liking. Objectives: The aim of the present study was to investigate the associations between liking for fat sensation and socio-demographic, economic, psychological, lifestyle and health characteristics in a large sample of adults. Method / Design: Individual factors and liking scores were collected using validated questionnaires from 37,181 French adults participating in the NutriNet-Santé study,…

Patrones espacio-temporales y ecología del comportamiento de aves limícolas en lagunas continentales
2018
Las áreas húmedas en su estado natural son fuentes de beneficio sustancial para la sociedad: almacenamiento de agua, protección contra inundaciones, recarga y descarga de acuíferos, purificación del agua, recreación y producción de granos y energía son algunas de las muchas funciones y valores que estos ecosistemas proporcionan. Esto hace que las áreas húmedas estén entre los ecosistemas más productivos de la Tierra, con enorme importancia ecológica y social para la humanidad, siendo la disponibilidad de los recursos hídricos un aspecto extremadamente importante para la sostenibilidad de una región. Por otra parte, más del 50% de los humedales alrededor del mundo ya han sido destruidos o mo…
Interindividual variability of food memory performance
2008
International audience; To investigate consumer's memory performance for a regularly product, 95 usual consumers of a precise soft-drink were invited to took part in a memory task, during which they were offered a series of samples, consisting in some samples identical to their favourite drink (target samples), and some samples slightly varying in sweetness, sourness of flavour intensity (distractor samples).

La gestión en educación física. Dos modelos de gestión, el mismo individuo
2020
In the development of this writing, we intend to critically analyze the idea of management in Physical Education and problematize it with the issues of inclusion and inequality. To do this, first there is a brief etymological review of the concept of management, and then we analyze how Physical Education links management to economic and business Sciences. The analysis material used are books, manuals and articles on Physical Education management. From the analysis of this material, the second point of the work arises to explain two management models in Physical Education that we call: individual management and self-management. These models are presented as different and opposite, but in the…
The Effects of Individual Values on Online Shopping Spending
2019
Although individual values have been found as important antecedents of human behaviour, their effects on online shopping behaviour remain poorly understood. In this study, we aim to address this gap in prior research by examining the effects of individual values on both total online shopping spending and the specific types of online shopping spending in terms of orders made (1) with traditional computers versus mobile devices, (2) from businesses versus other consumers, and (3) from domestic versus foreign online stores. The examination is based on the data from 565 Finnish online shoppers, which was collected via an online survey between February 2019 and March 2019 and is analysed by usin…
