Density fractionation reworked: Reduce material and costs

Increase Safety, Reduce Costs

Do hospital mergers reduce costs?

Proponents of hospital consolidation claim that mergers lead to significant cost savings, but there is little systematic evidence backing these claims. For a large sample of hospital mergers between 2000 and 2010, I estimate difference-in-differences models that compare cost trends at acquired hospitals to cost trends at hospitals whose ownership did not change. I find evidence of economically ...

Inflation with a stringy minimal length , reworked

In this paper we revisit the formulation of scalar field theories on de Sitter backgrounds subject to the generalized uncertainty principle (GUP). The GUP arises in several contexts in string theory, but is most readily thought of as resulting from using strings as effective probes of geometry, which suggests an uncertainty relation incorporating the string scale ls. After reviewing the string ...

Control Automation to Reduce Costs of Control

Much compliance effort concerns adherence to contracts. Controls are added to the business process to make sure the other party will fulfill his part of the contract. Controls have costs. In this paper we argue that fully automated controls help to lower control costs, because (i) they help to prevent misstatements (compliance by design) or (ii) they increase the quality of audit evidence and t...

Innovative approaches to reduce diabetes costs.

According to the American Diabetes Association, the cost of treating diabetes in North Carolina was approximately $5.3 billion in 2006. Reigning in diabetes-related costs requires collaboration between third-party payers, health care professionals, and people with diabetes. This article reviews innovative policy changes that affect all 3 groups and are intended to improve diabetes-associated ca...
