Hostos at the Hotel America
Rafael Bernabe
Centro Journal , 2009,
Abstract: For Eugenio María de Hostos, a veteran opponent of Spanish rule in Puerto Rico, the Spanish-American War posed a dilemma: he admired U.S. democracy, but feared its imperial inclinations. An account by the New York Times, republished here for the first time, helps trace Hostos s intervention in mid-1898. The introduction discusses five issues he raised between 1898 and 1903: the attitude toward U.S. occupation; the role of the United States as a democratic model; the duties of the United States in Puerto Rico; the possibility that it would deviate from them; Hostos s views on the turn of events after 1898.

Abstract: To assess a carbapenem-based de-escalating strategy in nosocomial pneumonia (NP), a prospective observational study was conducted in critically ill patients with NP treated empirically with imipenem ± aminoglycoside/glycopeptide in 24 intensive care units of Spanish general hospitals. Overall, 244 patients were assessable (91% with late-onset NP). The primary outcome was therapeutic success 7–9 days post therapy.Microbial identification – based on cultures of tracheal aspirates in 82% of patients, cultures of protected specimen brush in 33%, and cultures of bronchoalveolar lavage in 4% – was only available for 131 (54%) patients. Initial antibiotics were inadequate for 23 (9%) patients. Of the remaining patients, antibiotics were streamlined in 56 (23%) patients and remained unchanged in 14 (6%) patients based on microbiology data, in 38 (16%) patients despite microbiology data favouring de-escalation, and in 113 (46%) patients due to unknown aetiology. Overall, de-escalation was implemented in only 23% of patients with potentially multiresistant pathogens, compared with 68% of patients with the remaining pathogens (P < 0.001). Response rates were 53% for patients continuously treated with imipenem-based regimens and 50% for the de-escalated patients. Higher Acute Physiology, Age, and Chronic Health Evaluation II scores were associated with greater mortality, whereas adequate empiric antibiotic therapy protected against fatal outcomes. No increase of superinfection rates caused by emerging pathogens was observed. The costs associated with de-escalation were mainly dependent on the duration of hospitalization.This study mainly highlights the current practice of a specific algorithm of de-escalation solely based on the available microbiological data, and highlights the barriers to using it more widely. In this setting, de-escalation was less likely to occur in the presence of potentially multiresistant pathogens. Prior antibiotic administration and the low use of bron
A reassessment of the phytogeographic characterization of Temperate Pacific South America

Revista chilena de historia natural , 2000, DOI: 10.4067/S0716-078X2000000400005
Abstract: in 1980, a study of geographic distribution patterns and geographic affinities of benthic algae of temperate pacific south america (5-55 os) provided a first characterization of these coasts. high endemism and limited floristic exchange with the tropical pacific and with islands in the south pacific at various distances from the continent were two outstanding features of the marine flora. a partial blockage of species exchange partially accounted for a peculiar latitudinal pattern of species richness that increases with increasing latitudes. in contrast, there was reduced species richness in comparison with other climatically equivalent regions that have contact with more effective routes of migration. over the last two decades, more than 30 taxonomic and biogeographic studies on this benthic marine flora have been completed, adding a significant number of new records for the area. new studies test the above characterization and indicate that the new data add support to several key aspects of the phytogeographic characterization of this coastline. the relative importance of the various floristic components at different latitudes, the isolated character of this flora and the latitudinal pattern of increasing species richness to higher latitudes are shown

Revista chilena de historia natural , 2000, DOI: 10.4067/S0716-078X2000000400006
Abstract: according to biogeographic studies made two decades ago, marine benthic algal species of the pacific temperate coast of south america could be grouped into five components according to their geographic affinities. each of these components was distributed differentially along the coastline between 4o and 56os and thus, their contribution to the overall flora varied depending on the latitude. species composition changed at specific latitudes in such a way that three groups could be observed: from 4 to 6os, from 6 to 30os and from 30 to 55os. since 1980, new information on marine algae along this coastline allows a review of the previous phytogeographic characterization. the presence/absence of algal species, separated by division and geographic affinity, was recorded for each degree of latitude from 4o to 56os and used to analyze the similarity in species composition and possible changes in distribution patterns. results show the same five geographic components detected 20 years ago with similar distributions. differences observed are a further southward intrusion of subtropical elements, a decrease in endemic species number and relative contribution to the flora at the southern tip of south america, and two breaking points in species composition at 12o and 42os. another two breaking points occur at 20os and at 33os in phaeophyta and rhodophyta species composition respectively. the inclusion of single-record species does not affect significantly the distribution of species along this coastline

Abstract: In 1980, a study of geographic distribution patterns and geographic affinities of benthic algae of temperate Pacific South America (5-55 oS) provided a first characterization of these coasts. High endemism and limited floristic exchange with the Tropical Pacific and with islands in the South Pacific at various distances from the continent were two outstanding features of the marine flora. A partial blockage of species exchange partially accounted for a peculiar latitudinal pattern of species richness that increases with increasing latitudes. In contrast, there was reduced species richness in comparison with other climatically equivalent regions that have contact with more effective routes of migration. Over the last two decades, more than 30 taxonomic and biogeographic studies on this benthic marine flora have been completed, adding a significant number of new records for the area. New studies test the above characterization and indicate that the new data add support to several key aspects of the phytogeographic characterization of this coastline. The relative importance of the various floristic components at different latitudes, the isolated character of this flora and the latitudinal pattern of increasing species richness to higher latitudes are shown El estudio de los patrones de distribución geográfica de las algas marinas bentónicas en la costa temperada de Sudamérica (5-55 oS) permitió en 1980 caracterizar estas costas como con un alto grado de endemismo y con intercambio florístico limitado con localidades situadas en el Pacífico Tropical o con las islas oceánicas del Pacífico Sur dispuestas a distintas distancias de la costa. Este bloqueo parcial al intercambio de especies explicaría la baja riqueza de especies de estas costas en comparación con costas climáticamente equivalentes pero con un número mayor de vías de emigración así como el patrón latitudinal de riqueza de especies que en esta zona muestra un incremento en el número total de especies hacia latitudes mayores. En las últimas dos décadas en esta zona se ha realizado un número cercano a 30 estudios taxonómicos de algas bentónicas y fitogeográficos, agregando un número significativo de nuevos registros para el área. Una puesta a prueba de esta caracterización fitogeográfica a la luz de estos nuevos hallazgos indica que los nuevos datos agregan sustentación a la caracterización biogeográfica, incluyendo la importancia relativa de distintos componentes florísticos a distintas latitudes en estas costas, el carácter aislado de esta flora y el patrón latitudinal de incremento en riqueza de e

Abstract: According to biogeographic studies made two decades ago, marine benthic algal species of the Pacific temperate coast of South America could be grouped into five components according to their geographic affinities. Each of these components was distributed differentially along the coastline between 4o and 56oS and thus, their contribution to the overall flora varied depending on the latitude. Species composition changed at specific latitudes in such a way that three groups could be observed: from 4 to 6oS, from 6 to 30oS and from 30 to 55oS. Since 1980, new information on marine algae along this coastline allows a review of the previous phytogeographic characterization. The presence/absence of algal species, separated by division and geographic affinity, was recorded for each degree of latitude from 4o to 56oS and used to analyze the similarity in species composition and possible changes in distribution patterns. Results show the same five geographic components detected 20 years ago with similar distributions. Differences observed are a further southward intrusion of subtropical elements, a decrease in endemic species number and relative contribution to the flora at the southern tip of South America, and two breaking points in species composition at 12o and 42oS. Another two breaking points occur at 20oS and at 33oS in Phaeophyta and Rhodophyta species composition respectively. The inclusion of single-record species does not affect significantly the distribution of species along this coastline De acuerdo a estudios biogeográficos realizados hace 20 a os, las especies de algas marinas bentónicas de la costa temperada del Pacífico de Sudamérica se agrupan en 5 componentes de distinta afinidad geográfica. Cada uno de estos componentes posee una distribución diferencial a lo largo de estas costas entre los 4o y los 55oS. De esta forma su contribución a la flora varía dependiendo de la latitud. La composición de las especies cambia en determinadas latitudes de manera que se pueden reconocer tres grupos: uno se encuentra de 4o a 6oS, otro de 6o a 30oS y el tercero de 30o a 55oS. A partir de 1980, el aporte de nuevos estudios en algas ha permitido una revisión de esta caracterización fitogeográfica. La presencia /ausencia de las especies, separadas dentro de cada división por afinidad geográfica, fue registrada para cada grado de latitud entre los 4o y los 56oS, y usada para analizar la similitud en la composición de especies y los posibles cambios en sus patrones de distribución. Los resultados muestran los mismos 5 componentes geográficos encontrados 20 a os a
Two Reflections on Transnational Mobility in the Western Mediterranean
Bernabe Lopez Garcia
Revista CIDOB d'Afers Internacionals , 2000,
Abstract: The author replies to Alain Roussillon’s discussion with the following reflections: Is it the same thing to say “intercultural” in Rabat, Barcelona or Paris? He approaches transnational mobility in the Western Mediterranean through the migrants, their relationship with their country of origin and their children’s language/culture in the host countries.

CONSTRAINTS FROM LEPTON UNIVERSALITY AT THE Z PEAK ON UNIFIED THEORIES
J. Bernabe'u,A. Pilaftsis
Physics , 1995, DOI: 10.1016/0370-2693(95)00320-K
Abstract: We suggest the use of a universality-breaking observable based on lepton asymmetries as derived from the left-right asymmetry and the $\tau$ polarization at the $Z$ peak, which can efficiently constrain the parameter space of unified theories. The new observable is complementary to the leptonic partial width differences and it depends critically on the chirality of a possible non-universal $Z$-boson coupling to like-flavour leptons. The LEP/SLC potential of probing universality violation is discussed in representative low-energy extensions of the Standard Model (SM) that could be derived by supersymmetric grand unified theories, such as the SM with left-handed and/or right-handed neutral isosinglets, the left-right symmetric model, and the minimal supersymmetric SM.
