Objective: According to the cognitive reserve hypothesis (Stern, 2009), individuals who have developed a high level of reserve should resist better to the effects of aging than individuals with lower cognitive reserve. In this study, we identified the factors of cognitive reserve that impact most memory performance in aging. Methods: 118 healthy older participants performed one yes/no recognition task and one 3-alternative forced-choice recognition task. For each recognized item, participants provided a Remember/Know/Guess judgment. Furthermore, participants completed a questionnaire assessing different aspects of cognitive reserve (level of education, occupation, physical, social, cultural and intellectual activities). We determined the moderators of cognitive reserve that explain a significant proportion of variance for each memory index through stepwise regression analyzes (p<0.05). Results: In the forced-choice test, the level of education explained positively the use of recollection and negatively the level of false alarms associated with familiarity. In the yes/no recognition task, the precision of recognition was explained positively by the physical activities. Recollection was positively explained by the physical activities and the level of education. Finally, the level of false alarms associated with familiarity was explained negatively by the level of education although the precision of the use of the familiarity is explained positively by physical activities. Conclusion: The more older adults were educated and/or were practicing physical activities, the better their recollection was. The impact of the moderators of the cognitive reserve is dependent on the format of the recognition task. [less ▲]

On 26 May 2000, an estimated 250,000 people – Australian novelist and essayist Gail Jones included – walked across the Sydney Harbour Bridge in support of the Australian Reconciliation process. More importantly, eight years later, Jones claimed that “in writing [her novel Sorry] [she] rehearsed [her] own concern that the reconciliation process not be forgotten – since it has certainly faded from the political agenda since the bridge walk of 2000[” (2008: 84). This and her claim that “the heartwarming Sorry Books [...] ought seriously to be considered within the genre of the poetics of political dissent, and not as casual or sentimental acts of mere signature” (2008: 164) are indicative of Jones’s writing and of her wish to subvert the stereotypical and ambiguous discursive manifestations of the Australian Reconciliation. By the same token, her novels Sorry (2007) and Five Bells (2011) offer a complex picture of the ethics of reconciliation, namely one that includes “an admission of uncertainty, a calculation of difficulty, and an awareness that justice – and human relations – is rarely written in black and white” (Jones 2008: 86). My paper will thus seek to explore how Jones, by drawing on forms of narrative indirections in both, Sorry and Five Bells, distances herself from white Australian writers who deal with the Stolen Generations in a way that seems to appropriate Aboriginal and Torres Strait Islander peoples’ experiences. Sorry and Five Bells, then, offer an alternative to standard reconciliation practices, with a view to bridging the gap between white Australia’s history and the history of the Aborigines.

Objective. Normal aging is characterized by decreased recollection, but better preserved familiarity. Memory tasks that facilitate the use of familiarity should allow attenuating age-related differences in memory. The study tested two hypotheses: (1) can the reliance on familiarity during recognition memory be promoted by increasing the difference in perceptual processing fluency between old and new items; (2) can this manipulation reduce age-related difficulties in episodic memory? Methods. Twenty-four young and 24 older adults performed two verbal recognition memory tasks. In the No-Overlap task, target words and new words did not share any letter. Prior exposition to the target words thus induced increased processing fluency of the words and letters, so that fluency difference was a salient and reliable cue to discriminate between old and new words. In the Overlap task, target and new words had letters in common, so fluency cues were less useful. Recollection and familiarity was assessed with the Remember/Know/Guess paradigm. Results. There was an age effect on recollection but intact familiarity. Moreover, (1) memory performance was better in the No Overlap than the Overlap task, with a greater hit rate and a smaller false alarm rate associated with familiarity. (2) Age-related differences in recognition accuracy (hits – false alarms) were significantly attenuated in the No Overlap task compared to the Overlap task. Conclusion. These findings suggest that minimizing the perceptual similarity between targets and distractors, and thus increasing processing fluency differences, allowed to reduce the effect of age on recognition memory performance by facilitating the use of familiarity.

We compare two CO2 time series measured at the High Alpine Research Station Jungfraujoch (3580 m a.s.l., Switzerland) in the period from 2005 to 2013 with an in-situ surface measurement system using a nondispersive infrared analyzer (NDIR) and a ground-based remote sensing system using solar absorption Fourier Transform Infrared spectrometry (FTIR). Although the two data sets show an absolute shift of about 13 ppm, the slopes of the annual CO2 increase are in good agreement within their uncertainties. They are 2.04 ± 0.07 ppm yr-1 and 1.97 ± 0.05 ppm yr-1 for the FTIR and the NDIR system, respectively. The seasonality of the FTIR and the NDIR system is 4.46 ± 1.11 ppm and 10.10 ± 0.73 ppm, respectively. The difference is caused by a dampening of the CO2 signal with increasing altitude due to mixing processes. While the minima of both data series occur in the middle of August, the maxima of the two datasets differ by about ten weeks, the maximum of the FTIR measurements is in middle of January, whereas the maximum of the NDIR measurements is found at the end of March. Sensitivity analyses revealed that the air masses measured by the NDIR system at the surface of Jungfraujoch are mainly influenced by central Europe, whereas the air masses measured by the FTIR system in the column above Jungfraujoch are influenced by regions as far west as the Caribbean and the United States.

Introduction: The teaching’s evolution in nursing education has to answer the challenge to stimulate the student’s skills development. According to literature review, it’s necessary to compare High-Fidelity Simulation (HFS) with other pedagogical methods. Furthermore, the comparison with Problem Based Learning (PBL) was not studied yet. Methods: Two indicators were evaluated : student satisfaction self-confidence. For this, two validated scales were used : Student Satisfaction Learning Scale and Self-Confidence in Learning Using Simulations Scale. 141 nursing’s students were involved in the study. They were exposed to the two pedagogical methods (PBL and HFS). The experience was organized according a complete cross plan. Results: The results demonstrated a higher level of the student’s confidence and the student’s satisfaction in learning for the HFS compare to PBL. Carry-over effects were study. It was concerning the teaching style (questions 3 and 5) as well as the varieties of educational tools (questions 2 and 4). The perception of the value of the PBL during the second period was systematically lower while the score obtained for the HFS for the two periods remains almost identical. Conclusion: A clear superiority of the HFS compared with the PBL is perceived by the students. This result seems to open new opportunities with the HFS method in the education nursing student. Nevertheless, research must be conducted in order to better understand the value of this new pedagogic approach. [less ▲]

Cette thèse vise à analyser les organisations pastorales et leurs rôles dans la gestion des conflits fonciers. En Afrique subsaharienne et particulièrement au Niger, le foncier est au centre des enjeux de l’agro-pastoralisme. La sécurisation des droits d’accès aux ressources et des systèmes de tenure foncière sont essentiels pour la gestion et la résolution des conflits fonciers (Herrea et al., 2007). La région de Maradi constitue la zone de contact entre le Nord pastoral et le Sud agricole. Dans cette partie centrale où la pression foncière, aggravée par la croissance démographique, se pose avec acuité, le spectre des conflits fonciers est malheureusement devenu un phénomène chronique, une donnée permanente (GADO., 2000). La pluralité des normes et plusieurs sources de droit contribuent à complexifier le règlement des litiges fonciers entre acteurs dans les départements de Dakoro et Guidan Roumdji (Moutari., 2001). Or la dynamique globale des systèmes d’élevage est déterminée par la complémentarité des espaces agro-pastoraux. Cette complémentarité est remise en cause par ces pressions foncières et suscite des changements organisationnels dans les communautés du centre Sud du Niger (Yamba., 2004 ; 2000). C’est le rôle des associations pastorales à Dakoro et Bermo qui est l’objet de cette recherche. En effet les organisations paysannes en Afrique Subsaharienne et au Niger en particulier jouent un rôle important dans la définition des politiques agricoles et deviennent des conditions indiscutables de la réussite des actions à promouvoir à l’échelle locale (Courade et Deveze., 2006 ; Mercoiret, 2006 ; Mercoiret et al. 2004). La méthodologie de travail relève de l’approche ethnographique. Les outils et instruments d’enquête sont les questionnaires et les entretiens ouverts avec les acteurs locaux sur les dynamiques territoriales, les modes d’action des associations pastorales et les conflits fonciers. Les résultats viennent aussi des travaux et des documents des projets, des ONG et des rapports des services techniques de l’Etat. Pour un souci de fiabilité des données, nous avons tenu à réaliser des séances de restitution des données et de triangulations pour confronter les informations de diverses sources. Au total 104 personnes sont enquêtées dont 30 % auprès des associations. Ces investigations ont concerné aussi les secrétaires des commissions foncières, les préfets, les agents des projets et des ONG et le président du tribunal de Dakoro ainsi que les leaders pastoraux, les transhumants, les agriculteurs et associations pastorales.

BACKGROUNG: Depression is a highly prevalent disorder which is usually considered as differentially experienced depending on gender. Behavioral theories of depression pinpoint the importance of the behavioral avoidance in the maintenance of depression. However, little is known about the specific impact of the behavioral avoidance and activation on each depressive symptom as well as on gender differences on the behavioral features of depression. METHODS: This study’s aim was two-fold: (1) to assess the presence of gender differences on the BDI-II; (2) to investigate the respective predictive value of behavioral avoidance and of behavioral activation on each depressive symptom assessed by the BDI-II depending on gender. Community adults and adults attending mental healthcare composed the sample. RESULTS: Results showed differences in symptomatology profiles depending on gender (e.g. higher scores of sadness, self-criticalness in women, higher scores of past failure and loss of pleasure in men). Behavioral avoidance positively predicted almost all depressive symptoms in women and in men while behavioral activation negatively predicted almost all symptoms in both gender. Nevertheless, the strengths of these relationships were different for some symptoms (e.g. pessimism). LIMITATIONS: The use of self-report instruments; the lack of assessment of causal or precipitating factors of the depressive symptomatology; the higher number of women in the sample. CONCLUSIONS: Results are discussed with respect to previous findings and present clinical implications: (1) to underline the relevance of the combination of gender-specific assessment tools; (2) to highlight the need of tailored psychological intervention.
