Climats tropicaux d'aujourd'hui à demain : variabilité et changements
2008
Present and future tropical climates : their climate variability and their climate changes The oriffttality of tropical climates is re-examined under the light of climate variability and climate change, both present and future . The interannual variability of rainfall is on average larger in the tropics than in the extra-tropics, but it is also spatially more contrasted. Human communities have often responded to this constraint through efficient coping strategies. The regions showing the most variable climate do not necessarily have lower population densities, an indication that in the long run variability is not decisive. However, the recent demographic growth of these regions is often low…
Cropping system dynamics, climate variability, and seed losses among East African smallholder farmers: a retrospective survey.
2014
Abstract Climate variability directly affects traditional low input and rain-fed farming systems, but few studies have paid attention retrospectively to the cropping system’s ability to mitigate climate risk. This study analyzes the impacts of rainfall variability on farmers’ seed variety losses over time, considering changes in smallholder farming systems. The cropping system dynamics, in favoring maize at the expense of sorghum and pearl millet, have induced an increasing risk of seed loss during drought. Combining ecological anthropology and climatology, a retrospective survey asking farmers about the period 1961–2006 was carried out at three altitudinal levels (750, 950, and 1100 m) on …
Legumes and the environment
2017
Prod 2017-358a BAP GEAPSI INRA; International audience; The ability of legumes to fix atmospheric nitrogen gives them a crucial role in sustainable farming systems. Their presence can provide several other valuable ecological services. In Europe these assets have been neglected whilst developing highinput farming systems for maximizing yields. Diverse strategies are presented for maximizing ecological services provided by legumes in order to re-integrate them in cropping systems. Key words: Inputs, intercrop, ecological services, mineralization, weeds, N-fixation, value chain The second plenary session of the International Legume Society conference was dedicated to talks on “Legume and envi…
Soil organic carbon storage capacity of old and modern wheat varieties
2022
Despite the possible mitigation of carbon emissions by favoring carbon transfer to terrestrial carbon sinks, little is knownabout the capacity of different crop genotypes to enhance soil carbon sequestration. We hypothesize that carbon sequestrationpotential linked to old wheat varieties (released before 1960) is higher than the one linked to modern ones while old varietiesare known to develop bigger and deeper root systems. Moreover, modern varieties are often cultivated using syntheticchemical inputs known to modify soil carbon dynamics. We conducted a field experiment by cultivating four modern andfour old wheat varieties, with and without chemical inputs (nitrogen, herbicide and fungici…
Noise characterization of analog to digital converters for amplitude and phase noise measurements
2017
International audience; Improvements on electronic technology in recent years have allowed the application of digital techniques in phase noise metrology where low noise and high accuracy are required, yielding flexibility in systems implementation and setup. This results in measurement systems with extended capabilities, additional functionalities and ease of use. In most digital schemes the Analog to Digital Converters (ADCs) set the ultimate performance of the system, therefore the proper selection of this component is a critical issue. Currently, the information available in literature describes in depth the ADC features only at frequency offsets far from the carrier. However, the perfo…
Runs of homozygosity in the Italian goat breeds: impact of management practices in low-input systems
2021
Abstract Background Climate and farming systems, several of which are considered as low-input agricultural systems, vary between goat populations from Northern and Southern Italy and have led to different management practices. These processes have impacted genome shaping in terms of inbreeding and regions under selection and resulted in differences between the northern and southern populations. Both inbreeding and signatures of selection can be pinpointed by the analysis of runs of homozygosity (ROH), which provides useful information to assist the management of this species in different rural areas. Results We analyzed the ROH distribution and inbreeding (FROH) in 902 goats from the Italia…
Neighborhood resources associated with active travel in older adults: A cohort study in six European Countries
2020
Objectives: To study associations between perceived neighborhood resources and time spent by older adults in active travel. Methods: Respondents in six European countries, aged 65–85 years, reported on the perceived presence of neighborhood resources (parks, places to sit, public transportation, and facilities) with response options “a lot,” “some,” and “not at all.” Daily active travel time (total minutes of transport-related walking and cycling) was self-reported at the baseline (n = 2,695) and 12–18 months later (n = 2,189). Results: Reporting a lot of any of the separate resources (range B’s = 0.19–0.29) and some or a lot for all four resources (B = 0.22, 95% confidence interval [0.09, …
The Efficiency of Ambulatory Medical Services. Case Study - The Integrated Ambulatory Units of the Psychiatric Hospital “Dr. Gheorghe Preda” Sibiu
2017
Healthcare costs are an important issue for developed countries, focusing on accessibility, the quality of service and financial efficiency. The global direction of health insurance systems is to resolve the case through primary care, ambulatory and day hospital care. Hospitalizations need to be reduced. In psychiatry, however, there is a particular situation due to the increased incidence of new cases that cannot be treated by ambulatory care units. Efforts have been made to develop ambulances and service accessibility, to capitalize on benefits and to provide quality to patients. Although the number of services rendered significantly increased, in psychiatry there is an increase in the nu…
Revista de educación
2000
Resumen tomado de la publicación En este trabajo pretendemos realizar una aproximación al contenido de la calidad en la educación, aplicándolo al ámbito concreto de la educación intantil. Pensamos que el concepto de calidad tiene interés científico como instrumento de evaluación de la actividad educativa, así como interés práctico para la toma de decisiones respecto a la política educativa.

Liikkuvatko oppilaat välitunneilla? : Liikkuva koulu- hankkeessa mukana olleiden 4.-9. luokkalaisten oppilaiden välituntiaktiivisuus
2012
Latonen, E. & Pajunoja, T. 2012. Liikkuvatko oppilaat välitunneilla? Liikkuva koulu- hankkeessa mukana olleiden 4.- 9. luokkalaisten oppilaiden fyysinen aktiivisuus. Liikunta-pedagogiikan pro gradu- tutkielma, 89s. Tutkimuksen tarkoituksena oli selvittää 4.-9. luokkalaisten tyttöjen ja poikien, ala- ja ylä-koululaisten sekä kaupunki- ja maaseutukoulujen oppilaiden välitunnin viettopaikkaa ja fyysisen aktiivisuuden määrää välitunneilla. Lisäksi tarkastelimme koulun ulkopuolisen liikunnan yhteyttä välituntiliikuntaan, sukupuoleen, luokka-asteeseen ja asuinpaikkaan. Käytimme tutkimusaineistona Liikkuva koulu-hankkeesta saatua aineistoa, jotka kerättiin 4.-9. luokkien oppilailta syyslukukaudell…
