The susceptibility of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) to selected strains of the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin was evaluated through bioassays with direct immersion or foliar exposureunder laboratoryconditions.Results showed thatA.planipennisadultswere susceptible toB. bassiana andM. anisop...

The resolvase Sin regulates DNA strand exchange by assembling an elaborate interwound synaptosome containing catalytic and regulatory Sin tetramers, and an architectural DNA-bending protein. The crystal structure of the regulatory tetramer was recently solved, providing new insights into the structural basis for regulation. Here we describe the selection and characterization of two classes of S...
We present a general formalism for studying the interaction between laser fields and degenerate-Zeemansublevel atoms correct up to the first order in the weak probe field. We derive from this theory the equations of motion for a L-type system involving S1/2, F52↔P1/2, F851↔S1/2, F51 transitions in Rb atoms. These equations are used to numerically investigate the coherent population trapping ~CP...
What leads the United Nations Security Council (UNSC) to intervene in one conflict, but remain inactive in another? This paper analyzes all 221 documented conflicts between 1945 and 2011, trying to unveil the characteristics associated with UN intervention. Including geographical aspects, we find that proximity to two the five permanent members of the UNSC has a significant and meaningful effec...
The Kodila-Tedika & Bolito-Losembe (2014, ADR) finding on no evidence of causality flowing from State fragility to classical corruption or extreme corruption could have an important influence on academic and policy debates. Using updated data (1996-2010) from 53 African countries, we provide evidence of a positive (negative) nexus between political stability/no violence and corruption-control (...
UN Interventions: The Role of Geography This paper argues that UN military interventions are geographically biased. For every 1,000 kilometers of distance from the three Western permanent UNSC members (France, UK, US), the probability of a UN military intervention decreases by 4 percent. We are able to rule out several alternative explanations for the distance finding, such as differences by co...
