The aim of this study was to provide farmers an efficient tool for supporting optimal decisions in the beef heifer rearing process. The complexity of beef heifer management prompted the development of a model including decisions on the feeding level during prepuberty (age <10 mo), the time of weaning (age, BW, calendar month), the feeding level during the reproductive period (age ≥10 mo), and t...

In this article, we use a multimethod approach to shed light on the strategic use of presidential pets.We draw on primary source materials to demonstrate that pets are an important power center in theWhite House. Then we turn to presidents’ strategic use of their pets in public.We present a theoretical framework and statistical evidence to explore the conditions under which presidents are most ...

protocols thus permit many different sorts of systems to coordinate in ways that were previously impractical. For example, nobody ever actually wrote software to tie information about any hotel’s room inventory to every airline’s flight schedules. Yet every hotel now can do this. This same abstraction and generality also mean that many previously difficult local problems can now be solved easil...

Neuroacanthocytosis syndromes are characterized by the presence of “thorny” red blood cells and neurodegeneration of the basal ganglia, along with peripheral neuromuscular findings, seizures, and a variety of neuropsychiatric features. In recent years significant progress has been made in understanding the molecular pathophysiology of these disorders; cases are now identified as autosomal reces...
