BACKGROUND As new interventions to reduce childhood mortality are identified, careful consideration must be given to identifying populations that could benefit most from them. Promising reductions in childhood mortality reported in a large cluster randomized trial of mass drug administration (MDA) of azithromycin (AZM) prompted the development of visually compelling, easy-to-use tools that synt...

In poignant remembrance of the last Christmas in the Confederate White House, Varina Davis, First Lady of the Confederacy, reflected upon that special event in an extended article for the New York Sunday World, some thirty-two years after the Confederacy’s final Christmas. Davis recounted the event fondly and praised the transformation of her female peers into perfect models of Confederate endu...

This paper evaluates transformative policy innovations with respect to security and taxation in the three main Colombian cities: Bogotá, Medellín, and Cali. In the first two, such policies were associated with huge success. Elsewhere we (Gutiérrez et al. 2009) have tagged these transformation processes as ‘urban/metropolitan miracles’. The term comes from the fact that both common citizens and ...

In the past year, several papers on health outcomes in Korean veterans of the Vietnam War have been published. All of these papers base their exposure classifications on an ‘E4 score’ which is a proximity-based measure of ‘exposure opportunity’ calculated from a model developed at Columbia University. Calculation of an Exposure Opportunity Index (EOI) or E4 score from this model requires two in...

The American Board of Pathology (ABP) has recently approved a physician-scientist research pathway (PSRP) for pathologists in training. This new pathway was specifically created to increase the recruitment of new physician-scientists to our specialty. Other specialties, such as internal medicine, pediatrics, radiology/radiation oncology, and dermatology, have formally Board approved research tr...

Police investigation units represent a knowledge-intensive and time-critical environment. Knowledge sharing is a key process in investigations. In this paper, we present an empirical study of performance in police investigations. Police investigation units are defined as value shops, where primary detective work is performed. Knowledge sharing is found to have a significant influence on the pol...

We study the phase transition of the coalitional manipulation problem for generalized scoring rules. Previously it has been shown that, under some conditions on the distribution of votes, if the number of manipulators is o ( √ n), where n is the number of voters, then the probability that a random profile is manipulable by the coalition goes to zero as the number of voters goes to infinity, whe...

This report provides an overview of mentoring: the career enhancing and psychosocial functions, the stages of development in the mentoring relationship, and a selective review of the research literature. We argue that the traditional mentoring relationship is difficult to establish and maintain in a military environment for a number of reasons including the rank structure and job environment. T...
