\u3cem\u3eThe Spanish Earth\u3c/em\u3e and \u3cem\u3eSierra de Teruel\u3c/em\u3e: The Human Condition as Political Message

Compares two films on the Spanish Civil War that Hemingway and Malraux were involved in producing. Contends that The Spanish Earth and Sierra de Teruel, as propaganda, share a humanistic ideology intended to personalize the distant war in Spain and thus gain the sympathy of American and other democratic audiences

Interview with John J. Michalczyk and Raymond G. Helmick on Through a Lens Darkly: Films of Genocide, Ethnic Cleansing, and Atrocities, by John J. Michalczyk and Raymond G. Helmick

Michalczyk and Helmick have a particular interest in conflict resolution, and here they combine their expertise to create a well-crafted, informative collection of essays on the role of film in conveying the horrors of genocide and myriad human rights violations over the past two centuries. Whereas many studies of film and genocide focus on the Holocaust and, more recently, Rwanda, Michalczyk and Helmick's collection examines films on Native Americans, Armenians, the Rape of Nanking, Cambodia, the Balkans, the Sudan, and the Congo--as well as the Holocaust and Rwanda. They devote a section of the book to each, providing a broad yet cohesive perspective on this genre. The contributors are international scholars with expertise in diverse areas--philosophy, religion, history, and sociology--along with firsthand knowledge of and experience with genocide; each brings a unique point of view to the study of genocide and film. For example, Ajak Mabior contributes "No Heaven on Earth: Lost Boys of Sudan (2003)" and Willy Moko-Mubelo "Atrocities and Exploitation in the Democratic Republic of Congo." Surprisingly jargon-free, this collection makes an excellent resource for genocide and film studies. Recommended. All readers. Choice Review.Title supplied by cataloger

Joint neutron crystallographic and NMR solution studies of Tyr residue ionization and hydrogen bonding: Implications for enzyme-mediated proton transfer

Proton transfer is a fundamental mechanism at the core of many enzyme-catalyzed reactions. It is also exquisitely sensitive to a number of factors, including pH, electrostatics, proper active-site geometry, and chemistry. Carbonic anhydrase has evolved a fast and efficient way to conduct protons through a combination of hydrophilic amino acid side chains that coordinate a highly ordered H-bonded water network. This study uses a powerful approach, combining NMR solution studies with neutron protein crystallography, to determine the effect of pH and divalent cations on key residues involved in proton transfer in human carbonic anhydrase. The results have broad implications for our understanding of proton transfer and how subtle changes in ionization and H-bonding interactions can modulate enzyme catalysis
