Intercomparison of spanish advanced lidars in the framework of EARLINET
2007
To extend and reinforce the action of the EARLINET- ASOS project, a nucleus of Spanish advanced lidars was created. Four systems were intercompared satisfactorily in terms of backscatter coefficients at two elastic wavelengths. Peer Reviewed
A Long-term Approach to Teachers' Legitimate Cultural Practices: Stability in a Time of Change?
2015
National audience; While the link between legitimate culture and categories of graduates has been redefined in recent years, how much is this also true for schoolteachers? Sharing many of the dynamics experienced by other graduates and facing changes in their sociological characteristics, primary and secondary school teachers may have developed new cultural practices. Using Ministry of Culture and Communication surveys, I demonstrate that variations over time in cinema and theatre attendance and regular book reading are not the same for "primary school teachers and comparable occupations," "teachers in secondary and tertiary education, scientific occupations" and other categories of graduat…
Constant Hierarchic Patterns of Physical Functioning Across Seven Populations in Five Countries
1998
This research was aimed at identifying critical steps in the decline in physical function that often parallels aging. Six basic and nine instrumental activities of daily living (ADLs) were classified into four domains of disability characterized by specific underlying physical impairment. The hierarchical order of this classification was verified in two random samples representative of the older home-dwelling population. The concordance level of disability and results of performance-based measures of physical function were also tested. Finally, the cross-cultural reliability of the model was verified in seven population-based samples of older persons living in five European countries. In ol…
Patterns of Experienced Aging with a Finnish Cohort
1993
A cohort study of eighty-year old residents in Jyväskylä (pop. 66,000), central Finland, was carried out in 1990 as part of the EVERGREEN-project. A total of 262 persons born in 1910 were interviewed in the cohort study. The survey data produced a fairly accurate picture of the respondents' objective situation. In order to shed further light on how the respondents felt about growing old, tape recorded narrative stories were collected from a subsample of twenty persons (10 women and 10 men). The stories revealed the subjective meanings and evaluations attached by the individuals concerned to their own aging. Being members of the same culture and the same age cohort, they also shared the sam…

Comparison and multiresolution analysis of irregular meshes with appearance attributes
2004
We present in this dissertation a method to compare and to analyse irregular meshes with appearance attributes. First, we propose a mesh comparison method using a new attribute deviation metric. Considered meshes contain geometric and appearance attributes (e.g. color, texture,temperature). The proposed deviation assessment allows the computation of local attribute differences between two meshes. We present an application of this method to mesh simplification algorithm quality assessment.Then we propose two multiresolution analysis schemes for irregular meshes with appearance attributes. First, a mesh is decomposed in a discret number of levels of detail. We introduce a surface geometry rel…
A geometrical criterion for nonexistence of constant-sign solutions for some third-order two-point boundary value problems
2020
We give a simple geometrical criterion for the nonexistence of constant-sign solutions for a certain type of third-order two-point boundary value problem in terms of the behavior of nonlinearity in the equation. We also provide examples to illustrate the applicability of our results.
Study of the performance of a resolution criterion to characterise complex chromatograms with unknowns or without standards
2017
The search for best conditions in liquid chromatography is routinely carried out with information provided by chemical standards. However, sometimes there are samples with insufficient knowledge about their chemical composition. In other cases, identities of the components are known, but there are no standards available, and in other cases the identities of peaks in chromatograms taken under different conditions are ambiguous. Most resolution criteria used to measure separation performance cannot be applied to these samples. In this work, a global resolution function valid for all situations was developed based on automatic measurements of peak prominences (area fraction exceeding the line …
Argumentation Skills as Prerequisites for Collaborative Learning Among Finnish, French and English Secondary School Students.
2005
International audience; Argumentation skills of secondary school students were evaluated in Finland (n = 290), France (n = 54), and England (n = 41). The data were collected from 4 tasks comprising 7 variables. The results indicated that most of the students had correctly justified arguments and conclusions, and composed clear claims and relevant arguments. However, many students had difficulties in recognising the main claim and arguments for it in an expository text, and in commenting analytically on an argumentative text. Thus the students possessed the prerequisites for argumentative reasoning and writing but need further practice in analytical and critical reading.
La diversificación y consolidación de los servicios sociales para las personas mayores en España y Suecia
2011
La información sobre los servicios públicos para las personas mayores a menudo se limita a la atención residencial y a la ayuda a domicilio. Sin embargo, estos servicios básicos son en muchos países complementados o sustituidos por otros servicios de menor envergadura, como el transporte, comidas a domicilio, teleasistencia y centros de día. Esta diversificación partió de un racionamiento de los servicios para lograr una asignación más racional de los recursos y, si se podía, un menor gasto. En este trabajo se utilizan diversos datos sobre estos servicios en España y Suecia. Cuando se consideran todos los cuidados, la cobertura de atención es mucho mayor que si sólo se contemplan los servic…
