La fusión de los sefardís con los dominicanos

Enrique Ucko: Académico judío-alemán que llegó a República Dominicana, como refugiado, en 1939.Artículo publicado por primera vez en Cuadernos Dominicanos de Cultura, 1944, y en el que su autor explica cómo los judíos sefardíes, que empezaron a venir desde principios del siglo XIX al territorio que hoy es dominicano, terminaron fusionándose completamente con un pueblo que los acogió con calidez y fraternidad y que no mostró para con ellos ningún tipo de prejuicio religioso o racial. En este país, esas familias hebreas no se vieron forzadas a ocultar su origen, sino que, al contrario, pudieron enarbolarlo con orgullo. Muchos de sus descendientes asumieron el culto católico y ascendieron a los más altos puestos de la Iglesia Católica y del Estado sin que su condición hebrea reconocida significara ningún obstáculo. Otros muchos asumieron la masonería, culto en el que volvieron a encontrar el mesianismo, la cábala y todo el misticismo que en las formas del judaísmo ortodoxo y liberal ya no les satisfacían. El mejor símbolo de la fusión referida es el cementerio de la avenida Independencia de la ciudad de Santo Domingo, camposanto en el que las tumbas judías, cristianas y protestantes están todas juntas y mezcladas, y en el que panteones familiares judíos conjugan a la vez nichos o túmulos individuales con símbolos hebreos, cristianos o masónicos, signo de que los miembros de las familias judías asentadas en el país tuvieron la libertad de profesar distintas fes

Predicate Dispatching in the Common Lisp Object System

I have added support for predicate dispatching, a powerful generalization of other dispatching mechanisms, to the Common Lisp Object System (CLOS). To demonstrate its utility, I used predicate dispatching to enhance Weyl, a computer algebra system which doubles as a CLOS library. My result is Dispatching-Enhanced Weyl (DEW), a computer algebra system that I have demonstrated to be well suited for both users and programmers

Genetic Diversity of PCR-Positive, Culture-Negative and Culture-Positive Mycobacterium ulcerans Isolated from Buruli Ulcer Patients in Ghana.

Culture of Mycobacterium ulcerans from Buruli ulcer patients has very low sensitivity. Thus confirmation of M. ulcerans infection is primarily based on PCR directed against IS2404. In this study we compare the genotypes obtained by variable number of tandem repeat analysis of DNA from IS2404-PCR positive cultures with that obtained from IS2404 positive, culture-negative tissue. A significantly greater genetic heterogeneity was found among culture-negative samples compared with that found in cultured strains but a single genotype is over-represented in both sample sets. This study provides evidence that both the focal location of bacteria in a lesion as well as differences in the ability to culture a particular genotype may underlie the low sensitivity of culture. Though preliminary, data from this work also suggests that mycobacteria previously associated with fish disease (M. pseudoshottsii) may be pathogenic for humans

The origins of Avebury.

The Avebury henge is one of the famous megalithic monuments of the European Neolithic, yet much remains unknown about the detail and chronology of its construction. Here, the results of a new geophysical survey and re-examination of earlier excavation records illuminate the earliest beginnings of the monument. The authors suggest that Avebury's Southern Inner Circle was constructed to memorialise and monumentalise the site of a much earlier ‘foundational’ house. The significance here resides in the way that traces of habitation may take on special social and historical value, leading to their marking and commemoration through major acts of monument building
