Participatory research methods with young children : a systematic literature review
2023
This systematic literature review aimed to ascertain what participatory methods for young children have been used in peer-reviewed empirical articles. A systematic literature search yielded 75 articles. Based on their methodology, the studies were divided into six categories: (1) multi-method and the Mosaic approach, (2) observation and ethnography, (3) language-based methods, (4) visual methods, (5) creative and playful methods, and (6) children as co-researchers. The participatory features of these methods were then analyzed. The articles foregrounded the importance of the reflective use of methods, ethically grounded research practices, and carefully considering young children’s particip…
L'économie matérielle de la France (1830-2015). L'histoire d'un parasite ?
2018
This article explores the long-term dynamics of material use in France over a period of 185 years. It is based on material flow accounts that are perfectly consistent with the standards of Material Flows Analysis at the national economic scale. This work - which covers domestic extraction, imports and exports - is the first long-term study of material flows for France, with annual and national data for most of the period. Our database allows us to study the evolution of French metabolism during the industrialization of the country, together with the increasing dependence on abiotic materials. We highlight a singular metabolic trajectory: that of a state that benefits from successive world-s…
La mesure de l'efficacité scolaire par la méthode de l'enveloppe : test des filières alternatives de recrutement des enseignants dans le cadre du pro…

Data envelopment and school effectiveness: contract teachers' efficiency compared to civil servants in the Education for all process) In the context of EFA process, countries, in general the most depressed LDC, both constrained by scarcity of funding and urgency for expanding school access have set up new tracks for teacher recruitment on annually renewable contracts. Those teachers are often not professionally trained in regards with traditional pedagogical curricula. They receive much lower salaries than regular civil service teachers. This has been a controversial policy, but there is very limited evidence on the effectiveness or failure of contract teachers in improving student learning…
Obesity and survival in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathological subtypes: a pooled…
2013
Obesity is an unfavorable prognostic factor in breast cancer (BC) patients regardless of menopausal status and treatment received. However, the association between obesity and survival outcome by pathological subtype requires further clarification. METHODS: We performed a retrospective analysis including 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, GEICAM/9805, GEICAM/2003-02, and BCIRG 001) evaluating anthracyclines and taxanes as adjuvant treatments. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differences o…
Ģenētiskais algoritms optimizācijas metodēs
2017
Bakalaura darbā tiek aprakstīts ģenētiskais algoritms, kas ir viens no optimizācijas metožu jaunākajiem un mazāk pazīstamajiem algoritmiem. Teorijas apskatā aplūkots ģenētiskā algoritma konstrukcijas elementi: derīguma (fitness) funkcijas izveide, reproducēšanās, krustošanās un mutāciju operatori. Praktiskajā pielietojumu daļā apskatīti vairāki piemēri (tanī skaitā ceļojošā pārdevēja problēma). Piemēru realizācija veikta ar paketi R .Sniegts neliels metožu salīdzinājums.
On the ‘expanded local mode’ approach applied to the methane molecule: isotopic substitutions CH3D ←CH4 and CHD3 ←CH4
2014
Operator perturbation theory and the symmetry properties of the axially symmetric XYZ3 (C3v) type molecules are used for the determination of the spectroscopic parameters in the form of functions of structural parameters and parameters of the intramolecular potential function. Several relations between sets of spectroscopic parameters of these molecules are obtained. The ‘expanded local mode’ model and the general isotopic substitution theory are used to estimate the relations between spectroscopic parameters of CH3D and CHD3, on one hand, and with the Td symmetric isotopic species, CH4, on the other hand. Test calculations with the isotopic relations show that even without including prior …
