La Literatura como profeta de la Ciencia : Einstein y El Quijote : VII Escuela de Verano : Centro Regional de Educaci??n de Personas Adultas de la Comunidad de Madrid (CREPA) : 29 y 30 de junio de 2005

En este volumen se recogen las actas de la S??ptima Escuela de Verano de Educaci??n de Personas Adultas organizada por el Centro Regional de Personas Adultas (CREPA) y el Centro Regional de Innovaci??n y Formaci??n (CRIF) 'Las Acacias', de la Comunidad de Madrid. La celebraci??n del centenario de la teor??a de la relatividad, del cincuentenario de la muerte de Albert Einstein, y del IV centenario de la publicaci??n de El Quijote es el punto de partida de las ponencias, grupos de debate, talleres y comunicaciones llevados a cabo en este encuentro. Los trabajos est??n relacionados con la ciencia, la lengua, la literatura, las nuevas tecnolog??as, la formaci??n profesional, la interculturalidad, la psicolog??a, la educaci??n y el consumo.

A Albert Einstein : in memoriam

Reflexi??n sobre la concepci??n desarrollada por Albert Einstein sobre el espacio en su teor??a especial de la relatividad y sobre la gravedad en su teor??a general de la relatividad, que revoluciona las creencias tradicionales sobre el universo y funda la cosmolog??a moderna.

El centenario de Einstein.

Generació Einstein 3.0. La comunicació en un món nou

Imaginem-nos que volem vendre alguna cosa a un jove: un producte, una idea o potser unes pràctiques a la nostra empresa. Com ho faríeu? Quins mètodes podríeu fer servir? Ho faríeu de la mateixa manera que ho heu fet sempre? Penseu que els vostres anuncis, textos publicitaris, llocs web o cartells encara serien vàlids? Creieu que tots els diners invertits en comunicació i màrqueting us ajudarien a assolir l’objectiu? Si la resposta a aquestes preguntes és que sí, aleshores no cal que continueu llegint. Podeu continuar comunicant-vos amb els joves com ho heu fet fins ara, perquè us funciona. Però si us passa com a tots nosaltres i reconeixeu que la comunicació amb els joves no és tan fàcil, que de vegades us sembla que no us veuen o no us senten, aleshores us convidem a continuar llegint. No pretenem oferir totes les respostes, ja que no tenim la clau dels seus cors, però sí que volem mirar d’entendre el seu comportament, la seva manera de pensar i les seves accions

Movements and Habitat Use by Temperate-Nesting Canada Geese During the Postbreeding Period in Southern Québec

Individual behavior that reduces vulnerability to predation can affect population dynamics of animals. Temperate-nesting Canada Geese (Branta canadensis maxima) have increased steadily throughout the Atlantic flyway and have become a nuisance in some parts of their range. The objective of our study was to describe movements and habitat use during the postbreeding period of Canada Geese recently established in southern Québec. More specifically, we wanted to determine whether geese were using areas where hunting was allowed to assess the potential of harvest to control the number of geese. We tracked a sample of geese fitted with radio or conventional alphanumeric collars throughout the fall in three zones characterized by different habitats and hunting pressure. Before the hunting season, geese left the breeding area where hunting was allowed to reach suburban areas where firearm discharge was prohibited or hunters’ numbers were low. These postbreeding movements occurred when juveniles were approximately three months old. We observed few local movements among zones once migrant geese from northern breeding populations reached the study area. Radio-collared geese used mainly natural habitats (75.4 ± 2.6%), followed by urban (14.4 ± 2.7%), and agricultural habitats (10.3 ± 0.8%). They were located 73.8 ± 6.2% of the time in areas where hunting was prohibited. Geese that attended their juveniles during brood rearing were more prone to use areas where firearm discharge was restricted than geese that had abandoned or lost their brood. This study shows that under the prevailing regulations, the potential of hunting to manage the increasing breeding population of Canada Geese in southern Québec is limited.

Mean-field description of a dynamical collapse of a fermionic condensate in a trapped boson-fermion mixture

We suggest a time-dependent dynamical mean-field-hydrodynamic model for the collapse of a trapped boson-fermion condensate and perform numerical simulation based on it to understand some aspects of the experiment by Modugno et al. [Science 297, 2240 (2002)] on the collapse of the fermionic condensate in the K-40-Rb-87 mixture. We show that the mean-field model explains the formation of a stationary boson-fermion condensate at zero temperature with relative sizes compatible with experiment. This model is also found to yield a faithful representation of the collapse dynamics in qualitative agreement with experiment. In particular we consider the collapse of the fermionic condensate associated with (a) an increase of the number of bosonic atoms as in the experiment and (b) an increase of the attractive boson-fermion interaction using a Feshbach resonance. Suggestion for experiments of fermionic collapse using a Feshbach resonance is made.
