Pour qui sont ces civilisations ? Partie 1

Samuel P. Huntington définit une civilisation en termes psycho-culturels comme « une entité culturelle... comme la forme la plus élevée de regroupement d'individus culturellement identiques, forme qui caractérise un groupe humain de la manière la plus large indépendamment de ce qui le distingue des autres espèces ». Dans son article "If not Civilizations, then What ?", publié dans Foreign Affairs, en réponse à ses détracteurs, Huntington présuppose qu'il n'existe pas d'autre alternative civil..

Insights into the mechanism for gold catalysis: behaviour of gold(i) amide complexes in solution

We report the synthesis and activity of new mononuclear and dinuclear gold amide complexes . The dinuclear complexes and were characterised by single crystal X-ray analysis. We also report solution NMR and freezing point depression experiments to rationalise their behaviour in solution and question the de-ligation process invoked in gold catalysis

Failure of artesunate-mefloquine combination therapy for uncomplicated Plasmodium falciparum malaria in southern Cambodia

<p>Abstract</p> <p>Background</p> <p>Resistance to anti-malarial drugs hampers control efforts and increases the risk of morbidity and mortality from malaria. The efficacy of standard therapies for uncomplicated <it>Plasmodium falciparum </it>and <it>Plasmodium vivax </it>malaria was assessed in Chumkiri, Kampot Province, Cambodia.</p> <p>Methods</p> <p>One hundred fifty-one subjects with uncomplicated falciparum malaria received directly observed therapy with 12 mg/kg artesunate (over three days) and 25 mg/kg mefloquine, up to a maximum dose of 600 mg artesunate/1,000 mg mefloquine. One hundred nine subjects with uncomplicated vivax malaria received a total of 25 mg/kg chloroquine, up to a maximum dose of 1,500 mg, over three days. Subjects were followed for 42 days or until recurrent parasitaemia was observed. For <it>P. falciparum </it>infected subjects, PCR genotyping of <it>msp1</it>, <it>msp2</it>, and <it>glurp </it>was used to distinguish treatment failures from new infections. Treatment failure rates at days 28 and 42 were analyzed using both per protocol and Kaplan-Meier survival analysis. Real Time PCR was used to measure the copy number of the <it>pfmdr1 </it>gene and standard 48-hour isotopic hypoxanthine incorporation assays were used to measure IC₅₀for anti-malarial drugs.</p> <p>Results</p> <p>Among <it>P. falciparum </it>infected subjects, 47.0% were still parasitemic on day 2 and 11.3% on day 3. The PCR corrected treatment failure rates determined by survival analysis at 28 and 42 days were 13.1% and 18.8%, respectively. Treatment failure was associated with increased <it>pfmdr1 </it>copy number, higher initial parasitaemia, higher mefloquine IC₅₀, and longer time to parasite clearance. One <it>P. falciparum </it>isolate, from a treatment failure, had markedly elevated IC₅₀for both mefloquine (130 nM) and artesunate (6.7 nM). Among <it>P. vivax </it>infected subjects, 42.1% suffered recurrent <it>P. vivax </it>parasitaemia. None acquired new <it>P. falciparum </it>infection.</p> <p>Conclusion</p> <p>The results suggest that artesunate-mefloquine combination therapy is beginning to fail in southern Cambodia and that resistance is not confined to the provinces at the Thai-Cambodian border. It is unclear whether the treatment failures are due solely to mefloquine resistance or to artesunate resistance as well. The findings of delayed clearance times and elevated artesunate IC₅₀suggest that artesunate resistance may be emerging on a background of mefloquine resistance.</p

Agency, Values, and Well-Being: A Human Development Model

This paper argues that feelings of agency are linked to human well-being through a sequence of adaptive mechanisms that promote human development, once existential conditions become permissive. In the first part, we elaborate on the evolutionary logic of this model and outline why an evolutionary perspective is helpful to understand changes in values that give feelings of agency greater weight in shaping human well-being. In the second part, we test the key links in this model with data from the World Values Surveys using ecological regressions and multi-level models, covering some 80 societies worldwide. Empirically, we demonstrate evidence for the following sequence: (1) in response to widening opportunities of life, people place stronger emphasis on emancipative values, (2) in response to a stronger emphasis on emancipative values, feelings of agency gain greater weight in shaping people’s life satisfaction, (3) in response to a greater impact of agency feelings on life satisfaction, the level of life satisfaction itself rises. Further analyses show that this model is culturally universal because taking into account the strength of a society’s western tradition does not render insignificant these adaptive linkages. Precisely because of its universality, this is indeed a ‘human’ development model in a most general sense

Methodological perspectives and research implications

This study is one of a number done by academic and other research institutions for the Department of State as part of its external research program. The program is planned and coordinated by the Department of State Research Council and managed by the Office of External Research in the Bureau of Intelligence and Research. It is designed to supplement the Department's own research capabilities and to provide independent, expert views to policy officers and analysts on questions with important policy implications
