High patient turnover (patient throughput generated by admissions, discharges, and transfers) contributes to increased demands and resources for care. We examined how the relationship between registered nurse (RN) staffing and failure-to-rescue (FTR) varied with patient turnover levels by analyzing quarterly data from the University HealthSystem Consortium. The data included 42 hospitals, repre...

Recent populations of the red sunflower seed weevil, Smicronyx fulvus LeConte (Coleoptera: Curculionidae), have been inconsistent or declining, particularly in North Dakota. Consequently, research on weevil biology, including development of resistant germplasm, has been limited. To determine whether cold storage of diapausing larvae could be improved, nonconstant temperature treatments (fluctua...

Ferredoxin-triphosphopyridine nucleotide reductase (FTR) forms complexes with spinach ferredoxin, bacterial ferredoxin, rubredoxin, and flavodoxin. The protein-protein interactions are complete within 3 msec after mixing and the resulting complex contains 1 molecule of FTR and 1 molecule of electron carrier. Complex formation causes changes in the visible spectrum. The complexes are sensitive t...

Biosynthesis of the Caulobacter crescentus polar flagellum requires the expression of a large number of flagellar (fla) genes that are organized in a regulatory hierarchy of four classes (I to IV). The timing of fla gene expression in the cell cycle is determined by specialized forms of RNA polymerase and the appearance and/or activation of regulatory proteins. Here we report an investigation o...

The transcription of a group of flagellar genes is temporally and spatially regulated during the Caulobacter crescentus cell cycle. These genes all share the same 5' cis-regulatory elements: a sigma 54 promoter, a binding site for integration host factor (IHF), and an enhancer sequence, known as the ftr element. We have partially purified the ftr-binding proteins, and we show that they require ...

8.1 Introduction For most of recorded history, textual data have existed primarily in hardcopy format, and the related document retrieval process was essentially a manual task, possibly involving the assistance of cross-reference catalogs. By the mid-1960s, work was under way at the University of Pittsburgh to develop computer-assisted legal research systems [Harrington, 1984–85]. Also, during ...

The flbG (hook operon or transcription unit II) and flaN (transcription unit I) operons of Caulobacter crescentus have a -12, -24 nucleotide sequence motif that is very similar to those of the Nif and Ntr promoters of enteric bacteria and Rhizobium spp. and a conserved ftr (flagellar gene transcription regulation) sequence, previously designated II-1 (D. A. Mullin, S. A. Minnich, L.-S. Chen, an...

This paper examines the incentives that generation firms have in restructured electricity markets for supporting long-term transmission investments. In particular, we study whether generation firms, which arguably play a dominant role in the restructured electricity markets, have the incentives to fund or support social-welfare-improving transmission investments. We examine this question and ex...
