Looking up at the GUT / Planck World

The importance of the mass spectroscopy of the superparticles is emphasized. It will be shown that the gauge coupling constants give us information on the GUT-scale mass spectrum once the superparticle masses are known. The gaugino masses will provide us a model-independent test of the grand unification irrespective of the symmetry breaking pattern. The sfermion masses carry the information on ...

Looking Down , Around , and Up : Mechanistic

Accounts of mechanistic explanation have emphasized the importance of looking down—decomposing a mechanism into its parts and operations. Using research on visual processing as an exemplar, I illustrate how productive such research has been. But once multiple components of a mechanism have been identified, researchers also need to figure out how it is organized—they must look around and determi...

Looking up for AML in Down syndrome.

Children with trisomy 21/DS represent a clinically and genetically unique subset of pediatric patients with AML, with patients ,4 years of age having a 500-fold increased risk of developing the disease. Taub et al report improved event-free survival and overall survival in a prospective cohort of children with DS that examined the impact of early intensification of cytarabine therapy and reduct...

Looking Up and Looking Out: Career Mobility Effects of Demographic Similarity Among Professionals

We investigate the role of workgroup sex and race composition on the career mobility of professionals in ―up-or-out‖ organizations. We develop a nuanced perspective on the potential career mobility effects of workgroup demography by integrating the social identification processes of cohesion, competition, and comparison. Using five years of personnel data from a large law firm, we examine the i...
