Carreras polĂticas en la Junta Departamental de Florida :Â inestabilidad y amateurismo 1985-2005
ArtĂculo originalEste trabajo estudia las carreras polĂticas en Florida a partir del anĂĄlisis de los integrantes de la Junta Departamental de Florida entre 1985 y 2005. El tamaño de la circunscripciĂłn departamental surge como una variable relevante a la hora de explicar el patrĂłn de carrera dominante (de tipo alternativo) orientado principalmente hacia la polĂtica local. Asimismo, el estudio demuestra que Florida cuenta con elenco polĂtico inestable, con altas tasas de retiro de la polĂtica y bajas tasas de buscadores de reelecciĂłn. La debilidad del sistema polĂtico para mantener de un cuerpo legislativo estable, combinado con una caĂda del nivel educativo de los miembros de la Junta, configuran un escenario caracterizado por la baja profesionalizaciĂłn de la polĂtica y un extendido amateurismo a en el proceso de polĂticas pĂșblica
Restauration dâune zone corallienne dĂ©gradĂ©e et implantation d'un jardin corallien Ă Bora Bora, PolynĂ©sie française
The restoration of coral reef habitats by coral transplantation is a hot topic in the news
toda y due to the accelerating degradation of the coral reef ecosystem all over the world. There
is much discussion about research programs for the transplantation of corals and about ac tuai
field realizations and the motivation for coral reef restoration. But the implementation of such
a project depends on a social request considering local or global cultural and economical situations
. Projects are very costly and only applicable when important economical interests are
involved such as the fight against erosion or tourism development.
In the lagoon of Bora Bora in French Polynesia, a fringing zone, degraded by coral sand
extractions, led to an erosion of the coast damaging local private property in a sec tor weil oriented
toward tourism activities. The reconstruction of this degraded site (20,000 sq.m)
required physically filling up holes, implementation of spurs, and putting into place artificial
concrete structures to promote the natural colonization of corals and other reef organisms in
order to reduce swell impacts. The creation of a coral reef garden was also part of the project
with the transplantation of corals collected in the vicinity. Fifty groups of three different types
of concrete blocks have been set out on the site and six others constitute the coral reef garden
on which 311 coral colonies are transplanted.
Two and a half years after this restoration, the project proved to be successful. The coral
reef garden flourished; it showed much diversification and little mortality among the corals
colonies, and the natural colonization on the concrete substrate was teeming with corals, seaurchins,
mollusks, and fishes. But thirty months later, an exceptionally violent meteorological
and oceanographical situation led to a catastrophic event which caused many transplanted
coral as weil as natural colonies in the vicinity to be killed off. Lagoon waters temperatures
were recorded as high as 34°C and of the 311 transplanted coral colonies only 119 survived,
most of them bleached or partly dead. All colonies of the genus Acropora died, while those of
the genus Psammocora survived.
Methods for restoration and creation of coral reef gardens are highly controlled but they
cannot always escape such catastrophic events such as the one in Bora Bora in December 2001. Physical restoration was successful but the biological transplantation of corals failed.
Thus, when we consider how expansive a restoration project is, it is essential to conduct an
historical inquiry on a potential coral transplantation site before implementing any projectLes problĂšmes de restauration de zones coralliennes, avec transplantations de coraux,
sont à l'ordre du jour compte tenu de la dégradation accélérée de cet écosystÚme à la surface
de la planĂšte. Les motivations des recherches dans ce domaine et celles des projets de restauration
sur le terrain sont évoquées. Elles répondent à une demande sociale exprimée en fonction
de considérations culturelles et économiques. Les projets sont coûteux et ne peuvent concerner
que des cas trĂšs limitĂ©s avec des intĂ©rĂȘts Ă©conomiques importants (lutte contre
l' érosion, développement du tourisme).
à Bora Bora, en Polynésie française, une zone lagonaire frangeante, dégradée par des
extractions de sédiment corallien, provoquait une érosion littorale. Son ré-aménagement comporte
une restauration physique des lieux (comblement des fosses, réalisation d'épis...) et la
mise en place de structures artificielles pour permettre la colonisation naturelle de coraux et
autres organismes, afin de jouer le rÎle de brise houle. Ce projet s'accompagne de la création
d'un jardin corallien avec structures artificielles sur lesquelles sont fixés des transplants de
coraux. Deux ans et demi aprÚs la fin des travaux, le jardin corallien affiche une communauté
corallienne florissante et diversifiée avec trÚs peu de mortalité des colonies transplantées, une
croissance normale et la colonisation naturelle de coraux et d'autres organismes des récifs
coralliens (oursins, mollusques, poissons). Cependant, un événement météorologique et océanographique
exceptionnel, trente mois aprÚs la création du jardin corallien, a entraßné une
forte mortalité des coraux transplantés comme ceux naturellement en place dans le secteur. Si
les techniques nécessaires à la restauration de zones dégradées et à la création de jardins
coralliens sont totalement maßtrisées, ces réalisations n'échappent pas aux variations temporelles
des conditions de milieu qui peuvent ĂȘtre catastrophiques. Dans un tel cas, comme Ă
Bora Bora en décembre 2001, la restauration physique reste à l'actif de l'opération, mais
l'échec de la restauration biologique est à noter. Une étude historique, sur plusieurs décennies,
des zones sujettes à des mortalités exceptionnelles s'impose donc avant tout choix de
sites pour la réalisation de jardins coralliens dont les coûts sont trÚs élevé
Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTICâHF: baseline characteristics and comparison with contemporary clinical trials
Aims:
The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTICâHF) trial. Here we describe the baseline characteristics of participants in GALACTICâHF and how these compare with other contemporary trials.
Methods and Results:
Adults with established HFrEF, New York Heart Association functional class (NYHA)ââ„âII, EF â€35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokineticâguided dosing: 25, 37.5 or 50âmg bid). 8256 patients [male (79%), nonâwhite (22%), mean age 65âyears] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NTâproBNP 1971âpg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTICâHF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressureâ<â100âmmHg (n = 1127), estimated glomerular filtration rate <â30âmL/min/1.73 m2 (n = 528), and treated with sacubitrilâvalsartan at baseline (n = 1594).
Conclusions:
GALACTICâHF enrolled a wellâtreated, highârisk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation
Mollusques et faune benthique du lagon de Takapoto
Mollusques et faune benthique du lagon de Takapoto.
At least 93 species of Molluscs (58 Gastropods, 34 Bivalves, 1 Cephalopod) exist within the closed lagoon of the Takapoto atoll. The distribution by biotop and by bathymetric level is studied for the most abundant species ; they are Area ventricosa, Chama imbricata and Tridacna maxima for the endofauna, Rhinoclavis fasciatus, Vexillum cadaverosum, Fragum fragum and Lioconcha philippinarum for the epifauna. The Tridacna (14 million individuals â 530 tons of living matter) and the Area (38,5 millions â 340 tons) constitute most of the exemples of the malacological fauna, but the Mother-of-pearl, Pinctada margaritifera, intensively exploited in French Polynesia, is also the subject of quantitative estimates and breeding tests.
Along with Molluscs, Corals (mainly Porites, Millepora, Montipora), Echinoderms (Halodeima atra) and Crustaceas (Brachiurs) represent a significant amount of the marine Invertebrates, while the sciaphil fauna (a few species of Sponges) is scarce compared to what is located on the outer slope. In this case we have a fauna typical of a closed atoll, where the uniformity and proliferation of 2 or 3 species in each zoological phylum is opposed to heterogeneousness and wealth of species found in open lagoons like Rangiroa and Mururoa.Richard Georges, Salvat Bernard, Millous Olivier.

Scottish subtlety: André Morellet's comments on the Wealth of Nations
The manuscripts of Andre Morellet (kept in the Municipal Library of Lyons) contain numerous notebooks in which Adam Smith's Wealth of Nations is discussed. They are an interesting but little used source for the study of the early reception of Smith's work in France. The frequent comparisons Morellet makes between Smith's views and those of contemporary French economists provide new insights into the, often subtle similarities and differences between the leading economic theorists of the second half of the eighteenth century.Smith Turgot Physiocrats,
