Book Description
The reactive scattering for H- + H2 and H+ + H2 and its isotopologues were investigated using different methods. The studies aimed at providing insights into elementary reactions, and go beyond these to more complexchemical reactions. By comparison of the reaction probabilities of H+ + H2 using adiabatic and non-adiabatic methods, it was found that, at low collision energies, the reaction preferentially occurs adiabatically, but at higher collision energies non-adiabatic effects should be taken into account. For H- + H2 and its isotopologues, we can see that, at low collision energies, the reaction probabilities and reaction cross section using SM-PES and AY-PES are very similar but different from PS-PES. The reaction cross sections investigated with quasi-classical trajectoriesare higher than those calculated with quantum wavepackets. For the collision H- and D- with HD, the main reaction path ways are different with the different collision energies.

Book Description
Hélène Seydoux establece brillantemente cómo en la ópera, más que en otras formas artísticas –literatura, teatro o cine–, las mujeres reciben el máximo privilegio al otorgar a las cantantes el mayor espacio lírico. Seydoux analiza las grandes óperas de los grandes compositores y trata de buscar un modelo emblemático femenino que sirva como referente común en el ámbito del bel canto, mientras trata de buscar paralelismos con la época, la sociedad, el momento en el que las óperas fueron creadas intentando establecer hasta que punto estas son reflejo de esas condiciones. Porque la ópera también es una interpretación del mundo. La autora, se aleja de la tesis de la musicología y ayuda al lector a descubrir (o a redescubrir) los placeres de la tragedia lírica, la comedia bufa o el drama jocular.

Book Description
In classical mythology Astraea, the goddess of justice, chastity, and truth, was the last of the immortals to leave Earth with the decline of the ages. Her return was to signal the dawn of a new Golden Age. This myth not only survived the Christian Middle Ages but also became a commonplace in the Renaissance when courtly poets praised their patrons and princes by claiming that Astraea guided them. The literary cult of Astraea persisted in the sixteenth century as writers saw in Elizabeth I of England the imperial Astraea who would lead mankind to peace through universal rule. This and other late flowerings of the Astraea myth should not be taken as the final phases of her history. Frederick A. de Armas documents in this book what may well be the last great rebirth of Astraea, one that is probably of greater political, religious, and literary significance than others previously described by historians and literary critics. The Return of Astraea focuses on the seventeenth-century Spanish playwright Pedro Calderón de la Barca, and analyzes the deity's presence in thirteen of his plays, including his masterpiece, La Vida es Sueho. Her popularity in this period is partially attributed to political motives, reflecting the aspirations and fears of the Spanish monarch Philip IV. In this broad study, grounded on such diverse fields as astrology, iconography, history, mythology, and philosophy, de Armas explains that Astraea adopts many guises in Calderón's dramas. Ranging from the Kabbalah to Platonic thought and from satires on Olivares to cosmogonic myths, he analyzes and reinterprets Calderón's theater from a wide range of perspectives centered on the playwright's utilization of the myth of Astraea. The book thus represents a new view of Calderón's dramaturgy and also documents the popularity and significance of this astral-imperial myth during the Spanish Golden Age.

Book Description
Costa Picazo recopila, traduce y anota las poesías de guerra de cinco poetas ingleses (Edmund Blunden, Robert Graves, Wilfred Owen, Isaac Rosenberg y Siegfried Sassoon) y un grupo de mujeres poetas (Marian Allen, Nora Bomford, Vera Brittain, Eleanor Farjeon, Charlotte Mew, May Sinclair y Elizabeth Underhill, entre otras). Tierra de nadie es un libro acerca de una de las guerras más terribles del siglo XX, en la que más de setenta y cinco millones de hombres fueron movilizados y más de la mitad resultaron muertos o desaparecidos. Es un libro sobre el horror de la guerra y, a pesar del espanto, sobre poesía. La Gran Guerra fue una contienda de trincheras, de dos frentes enemigos separados por un vacío que no era de nadie. Las profundas excavaciones, situadas en lados opuestos, prote-gidas por alambre de púa y ametralladoras, estaban separadas por una extensión de terreno infértil, que la lluvia y el defectuoso sistema de desagües convertían en lodazal. Las trincheras eran un claro ejemplo de deterioro y putrefacción. Allí se amontonaban los vivos y los muertos, estos últimos absorbidos por el fango y todos en medio de las ratas y el hedor. En ese contexto, cinco poetas ingleses (Edmund Blunden, Robert Graves, Wilfred Owen, Isaac Rosenberg y Siegfried Sassoon) y un grupo de mujeres poetas (Marian Allen, Nora Bomford, Vera Brittain, Eleanor Farjeon, Charlotte Mew, May Sinclair y Elizabeth Underhill, entre otras) demostraron que el espíritu humano sobrevive al horror y es capaz de afirmarse en medio del caos, y eternizarse.

Book Description
La anorexia y la bulimia son trastornos de la conducta alimentaria en alarmante expansión. Difundidas sobre todo entre las mujeres adolescentes, expresan sin embargo un sufrimiento que va más allá del problema nutricional. Este libro quiere devolver a estos trastornos el significado de «fenómenos complejos», en los que se entrecruzan influencias socioculturales, relacionadas con las profundas transformaciones del rol de la mujer en una sociedad que exhibe cuerpos eternamente jóvenes y eficientes; aspectos psicológicos individuales, que en la problemática relación con el cuerpo expresan dificultad para asumir el crecimiento; y dinámicas familiares, donde la rigidez de los lazos y mitos compartidos parecen detener las propias capacidades evolutivas de las jóvenes. Hay pues un hilo conductor que atraviesa los múltiples componentes invo-lucrados en estos trastornos: el imposible intento de suspender el tiempo del desarrollo y del crecimiento. De este tiempo suspendido, el cuerpo anoréxico y bulímico ofrece una sugestiva metáfora, cuyos significados se van reconstruyendo pacientemente en esta obra. Una guía esencial que ayudará a comprender mejor el sentido de un sufrimiento cada vez más extendido entre las generaciones jóvenes.

Book Description
Ranging from fatherhood to machismo and from public health to housework, Changing Men and Masculinities in Latin America is a collection of pioneering studies of what it means to be a man in Latin America. Matthew C. Gutmann brings together essays by well-known U.S. Latin Americanists and newly translated essays by noted Latin American scholars. Historically grounded and attuned to global political and economic changes, this collection investigates what, if anything, is distinctive about and common to masculinity across Latin America at the same time that it considers the relative benefits and drawbacks of studies focusing on men there. Demonstrating that attention to masculinities does not thwart feminism, the contributors illuminate the changing relationships between men and women and among men of different ethnic groups, sexual orientations, and classes. The contributors look at Mexico, Argentina, Ecuador, Brazil, Colombia, Peru, Venezuela, Chile, and the United States. They bring to bear a number of disciplines—anthropology, history, literature, public health, and sociology—and a variety of methodologies including ethnography, literary criticism, and statistical analysis. Whether analyzing rape legislation in Argentina, the unique space for candid discussions of masculinity created in an Alcoholics Anonymous group in Mexico, the role of shame in shaping Chicana and Chicano identities and gender relations, or homosexuality in Brazil, Changing Men and Masculinities highlights the complex distinctions between normative conceptions of masculinity in Latin America and the actual experiences and thoughts of particular men and women.
