La presente tesis gravita en torno a la siguiente pregunta: ¿cómo puede ser el liberalismo político una alternativa frente a los desafíos del multiculturalismo? La respuesta se presenta a partir de tres capítulos: en el primero se especifica la estructura y contenido del liberalismo político; en el segundo se caracterizan los desafíos del multiculturalismo en Francia, a partir del asunto del velo islámico y las consideraciones de los actores involucrados; en el tercero se analizan los argumentos y opiniones sobre el asunto del velo en Francia, con base en las catego­as específicas del liberalismo político, especialmente el consenso traslapado. Se concluye que las posibilidades de consenso dependen del apego que tengan los ciudadanos hacia ciertos valores propios de una concepción política de la justicia, de la capacidad para apartarse de su forma particular de ver el mundo (doctrina comprensiva) en las discusiones públicas, así como de la voluntad que tengan los individuos para ser razonables y respetar las directivas de indagación en las discusiones políticas.

Pertenecientes al grupo de la generación perdida. Hemingway, contrariamente a los otros escritores de su generación, poseía una muy escasa preparación académica, estaba dedicado al periodismo. Pero, su estilo desnudo y difícil, a pesar de su aparente sencillez, comenzó a llamar la atención hacia sus extrañas creaciones. Vivió en España al ser un amante de los toros y sentirse atraído por la causa repubicana.Steinbeck, cuatro años más joven que Ernest, pero novelista más saludable, con calidades más finas y saludables que sus compañeros. En Jhon, se unen la agudeza y la sensibilidad, el amor y la gracia amable, grotesca, a veces, pero sin mala intención y una ternura por el hombre pobre, por el torpe, que engrandecen sus novelas.

Combinations of drugs are increasingly being used for a wide variety of diseases and conditions. A pre-clinical study may allow the investigation of the response at a large number of dose combinations. In determining the response to a drug combination, interest may lie in seeking evidence of synergism, in which the joint action is greater than the actions of the individual drugs, or of antagonism, in which it is less. Two well-known response surface models representing no interaction are Loewe additivity and Bliss independence, and Loewe or Bliss synergism or antagonism is defined relative to these. We illustrate an approach to fitting these models for the case in which the marginal single drug dose-response relationships are represented by four-parameter logistic curves with common upper and lower limits, and where the response variable is normally distributed with a common variance about the dose-response curve. When the dose-response curves are not parallel, the relative potency of the two drugs varies according to the magnitude of the desired effect and the models for Loewe additivity and synergism/antagonism cannot be explicitly expressed. We present an iterative approach to fitting these models without the assumption of parallel dose-response curves. A goodness-of-fit test based on residuals is also described. Implementation using the SAS NLIN procedure is illustrated using data from a pre-clinical study. Copyright © 2007 John Wiley & Sons, Ltd.
