Determinants of the interannual relationships between remote sensed photosynthetic activity and rainfall in tropical Africa
2007
International audience; The response of photosynthetic activity to interannual rainfall variations in Africa South of the Sahara is examined using 20 years (1981-2000) of Normalised Difference Vegetation Index (NDVI) AVHRR data. Linear correlations and regressions were computed between annual NDVI and annual rainfall at a 0.5° latitude/longitude resolution, based on two gridded precipitation datasets (Climate Prediction Center Merged Analysis of Precipitation [CMAP] and Climatic Research Unit [CRU]). The spatial patterns were then examined to detect how they relate to the mean annual rainfall amounts, land-cover types as from the Global Land Cover 2000 data set, soil properties and soil typ…
From Mobile Crimes to Crimes of Mobility
2020
Piipponen, Mäntymäki and Rodi-Risberg suggest that many contemporary crime narratives across the globe host a heightened interest in diverse and ambiguous mobilities, border crossings and borderlands. They propose that such mobilities and crossings reflect on recent sociocultural developments on local and global levels and communicate specific geopolitical anxieties. They position their own mobilities research perspective within existing crime fiction scholarship, especially within the so-called transnational and spatial turns. Introducing some key observations of mobilities research, they suggest that mobility can be considered both as an object of study in its own right and a critical len…
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
The global ranking game : narrowing academic excellence through numerical objectification
2018
The objective of this article is to study some of the intended and unintended effects on academe of the evolving global ranking game. I will start with some broader points on the global ranking game, the formal terms and economic interests it promotes, then continue with a presentation of the Shanghai ranking and its main rival the Times Higher Education. Through reversed engineering, I will bring out the main problems of the Shanghai ranking. I will finish with some of the key features of the demand side, the uses and effects of the tool: the psychosocial mechanisms that reproduce ranking and the lock-ins it creates. peerReviewed

Teoría de la educación : educación y cultura en la sociedad de la información
2011
Se exponen las principales perspectivas en el estudio del comportamiento informacional: la perspectiva del usuario y la del sistema. En el primer caso, se asume una visión global del proceso de búsqueda de información y se desarrollan modelos teóricos y metodológicos para guiar la investigación en este campo. Se presentan como ejemplo la teoría del Sense-Making de Brenda Dervin y el modelo de Proceso de Búsqueda de Información de Carol Kuhlthau. En el segundo caso, se asume una perspectiva parcial del proceso de búsqueda de información, centrándose fundamentalmente en las transacciones entre usuario y el sistema o entre el usuario y la información. Se describen los estudios del uso de recur…
Subtropical streams harbour higher genus richness and lower abundance of insects compared to boreal streams, but scale matters
2018
Aim: Biological diversity typically varies between climatically different regions, and regions closer to the equator often support higher numbers of taxa than those closer to the poles. However, these trends have been assessed for a few organism groups, and the existing studies have rarely been based on extensive identical surveys in different climatic regions. Location: We conducted standardized surveys of wadeable streams in a boreal (western Finland) and a subtropical (south-eastern Brazil) region, sampling insects identically from 100 streams in each region and measuring the same environmental variables in both regions. Taxon: Aquatic insects. Methods: Comparisons were made at the scale…
Funkcje i zadania edukacji regionalnej
2017
In the paper, the author presents the position of sociologists and educators talking about the regional education. He compares their interpretations concerning the basie terms, such as: regionalism, cultural heritage, regional education, or regional identity. The article is a reflection showing the influence of ”the global village” and glocalisation on the formation of regional enclaves striving for the broadly understood identity. The leitmotiv of discussion is the sentence: ”think globally-act locally.”
