Se proposant de réinterpréter le cogito à partir de l'idée de l'âme et la preuve de l'existence du moi, ce livre montre qu'il existe une théorie psychologique de l'âme qui met l'accent sur les aspects constitutifs du cogito. Parlant de son identité cartésienne, il importe de prendre en compte son contenu propositionnel. A partir de l'explication de notions comme moi, existence ou pensée, l'ouvrage arrive à la conclusion selon laquelle l'axiome 'pour penser, il faut être,' explique et légitime le passage (...) du Je pense au Je suis. Or pour parvenir à la nature gnoséologique de la pensée, il importe de savoir que l'immédiateté existentielle de la pensée se conjugue avec sa complexité logique. Ce propos s'achève sur la question de l'être de la pensée tout en montrant que la généalogie propre au cogito couvre l'exigence d'une investigation sur l'être de Dieu."--Page 4 of cover. (shrink)

Niger is regularly affected by food insecurity, mainly due to the high sensitivity of its agricultural sector to climate variability. Despite the support from multiple development institutions and households’ willingness to address food security, hunger and malnutrition continue to challenge many vulnerable households. This study aims to analyze household livelihood strategies toward food security and assess factors determining their resilience. To address the issue, cluster analysis and the principal component analysis were used to identify the different livelihood strategies and to (...) construct a resilience index, respectively. Regression analysis was used to identify the most significant factors determining households’ resilience. The results indicate there were six different household types—pastoralist-extensive agriculturalists, farmers, agro-pastoralists, public service employees, entrepreneurs and wage employees—however, the majority of households obtained their livelihood from both agriculture and livestock (agro-pastoral systems). The principal component analysis highlighted that the pastoralist-extensive agriculturalists are the most resilient followed by public service employees, while households focused on wage labor are the least resilient, followed by entrepreneurs. In terms of gender, the study reveals that households headed by men are more resilient than those headed by women. However, the resilience components including income and food access, assets and adaptive capacity are the most correlated with the households’ resilience to food insecurity. Furthermore, the regression analysis results reveal that the household size, crop production, farming experience, livestock size and number of coping strategies are the most significant factors determining household resilience to food insecurity. Consequently, to face the challenges of climate change and food security, rational investments in agriculture are necessary to transit rural household land-use practices to climate-smart agriculture.
