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…
In-mouth mechanism leading to the perception of fat in humans: from detection to preferences. The particular role of saliva
2013
In humans, the perception of fat in food is a complex process involving many sensory modalities (texture, aromaand flavour). Themouth is the first place in which the process of digestion begins. During this process, a bolus is formed in which saliva is significantly incorporated. For solids and semi-solid fatty matrices, saliva and the shear forces applied during mastication contribute to their breakdown and/or destabilisation in emulsified systems. These mechanisms are often dependent on the fat content of the food and thus play an important role in not only the perception of texture but also the release of compounds responsible for the flavour of “fat”. In addition, saliva is directly inv…
The "Film and Creative Engagement Project" : Audiovisual Accessibility and Telecollaboration
2020
ABSTRACT: Globalisation and the advancement of ICTs invite the development of learners’ strategies and communication skills in higher education to participate fully in digitally networked societies. This paper analyses the results of a pilot study which is part of Film and Creative Engagement (FaCE), a collaborative research project between Manchester Metropolitan University (MMU), UK, and Instituto Tecnológico de Estudios Superiores de Monterrey (ITESM), Campus Laguna in Torreón, Mexico. There were two main aims: (1) to create a short project that was inspiring, stimulating and enjoyable that could be transferable to other high education institutions; and (2) to provide a training that cou…
Influence of bioremediation stimulators in soil on development of oat seedlings (Avena sativa) and their aminopeptidase activity / Wpływ pozostałości…
2015
Abstract The selection of bioremediation techniques is important for purification of contaminated soil for agricultural use. Studies on soil contaminated with petroleum substances have indicated that the applied method of remediation has a bigger impact on the development of oat seedlings than the level of contamination. A yeast inoculum appeared to be a technique which was the friendliest to vegetation of oat
Zones d'ammonites et de foraminifères du Vraconnien au Turonien : Une comparasion entre les domaines boréal et téthysien (NW Europe / Tunisie central…
2008
International audience; Depuis la fin du 19ème siècle, l'intervalle comprenant l'Albien supérieur élevé, le Cénomanien, le Turonien et le Coniacien basal a été subdivisé d'abord en zones d'ammonites puis, à partir du milieu du 20ème siècle, en zones de foraminifères planctoniques, deux groupes de macro- et de microfossiles particulièrement efficaces en bio-chronostratigraphie grâce à leur taux d'évolution rapide. Toutefois, des différences de compositions fauniques entre le domaine boréal (Europe du Nord-Ouest) et le domaine téthysien (Méditerranée) ont longtemps empêché des corrélations précises entre ces deux domaines. Aujourd'hui, dans un intervalle de temps couvrant environ 16 millions …
A methodological approach exploiting modern techniques for forest road network planning
2016
A well-developed road network allows all forest activities, including wood harvesting, firefighting and recreational activities. However, forest road construction and maintenance involve economic and environmental costs. For these reasons, forest road network planning is a fundamental phase of forest management, maximising the benefits and reducing costs and impacts. Thanks to modern technologies in data collection both for terrestrial and forest characteristics, new methods and tools have been developed to improve and facilitate road planning. The aim of this study was the development of a Decision Support System for helping managers during forest road network planning, exploiting Multi-Cr…
La enseñanza de la física cuántica: una comparativa de tres países
2020
espanolLa investigacion en ensenanza de la teoria cuantica en los niveles medio, de formacion docente y en carreras universitarias es un tema de actualidad. Aqui presentaremos algunos de nuestros estudios sobre este tema, los cuales fueron realizados junto a otros colegas en Espana, Argentina y Colombia, en ese orden temporal. La metodologia utilizada fue el analisis de los curriculos vigentes de nivel medio y de formacion docente, de libros de textos y entrevistas semi estructuradas a docentes. A ello, se suma una reflexion sobre algunas propuestas de transformacion didactica de las que hemos participado. Es muy interesante el hecho de que, mas alla de las diferencias en tiempos y sistemas…
Evolución de las concepciones de los docentes sobre dualidad en la física cuántica
2021
Este estudio muestra los cambios de concepciones sobre el concepto de dualidad en física cuántica en un grupo de docentes, antes y después de un curso de capacitación. Se presentan diagramas de evolución como instrumento metodológico para analizar y visualizar resultados. Los diagramas de evolución muestran categorías iniciales y de llegada de las concepciones de los profesores, que participaron de una secuencia de enseñanza-aprendizaje basada en la discusión de los modelos clásicos de ondas y partículas, de sus límites de validez y de las contribuciones de cada uno al modelo actual de estructura de la materia, en que no se habla de ondas, ni partículas, sino de características diferentes a…

Whose voice? Understanding stakeholder involvement in law drafting affecting Sami reindeer herding
2019
A communication and a legal approach are combined to investigate stakehold-er involvement in law drafting affecting Sami reindeer herding. The thesis fo-cuses on Finland, participation in law drafting in the Act on Metsähallitus (For-est Management and Park Services) and consultation related to the adoption of the International Labour Organization (ILO) Convention No. 169 concerning Indigenous and Tribal Peoples in Independent Countries. The research aims at gaining a better understanding of communication preceding and during law drafting processes regarding indigenous land use. It clarifies the changing con-text of the law drafting in which the issue of land use is addressed. Study 1 provi…
