Driving Strategies in Performance Excellence
Only a small number of U.S. businesses have implemented the Baldrige Criteria for Performance Excellence to improve their performance. The purpose of this multiple case study was to explore strategies that executive business leaders use to implement the Baldrige Criteria for Performance Excellence. The study population consisted of 6 business executives and 2 organizations in the U.S. state of Texas, all with experience in implementing the Baldrige Criteria for Performance Excellence. The theory of high performance work systems provided the conceptual framework for the study. Data were gathered from interviews and record reviews that were conducted within the organizations. Inductive analysis was used to identify words, phrases, ideas, and actions that were consistent among participants and organizations as well as to identify patterns and themes. Triangulation of sources between the interview and record review data was used for consistency. Three main themes emerged from data analysis: organizational leaders embedded the Baldrige Criteria for Performance Excellence into native work models; they also used robust strategy deployment systems with accountability for action plans to spread the Baldrige Criteria for Performance Excellence; and, rather than specifically create goals to align with the Baldrige Criteria for Performance Excellence, they identified actions to reach organizational strategic goals that were created using the Criteria as a business model. Implications for positive social change arising from this study include the potential to increase the number of available jobs by improving overall organizational performance through the increased implementation and use of the Baldrige Criteria for Performance Excellence among U.S. organizations
Soil Chemistry Analysis as an Effective Cultural Resource Management Tool: A Magical Mystery Tour
In Situ Recalibration of Ion Selective Electrodes
Reference electrode drift resulting from the exchange of ions at the solution/reference electrode chamber interface is the number one reason why ion selective electrodes and pH sensors in particular require recalibration, costing companies up to 70 % of the total lifetime cost of a pH probe. In this work, a novel and innovative methodology is proposed in which the reference potential is tracked, allowing for in-situ recalibration of the sensor without the need for end-user intervention
Anti-CTLA-4 (CD 152) monoclonal antibody-induced autoimmune interstitial nephritis
Targeted immune-modulating agents are entering clinical practice in many specialties, providing novel therapeutic possibilities but introducing new potential toxicities. We present the first reported case, to our knowledge, of immune-mediated nephritis following the administration of Tremelimumab (CP-675, 206), an anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) monoclonal antibody. High-dose steroid therapy led to a rapid improvement in renal function, avoiding the need for renal replacement therapy.Peer reviewe
Abnormal arterial-venous fusions and fate specification in mouse embryos lacking blood flow.
The functions of blood flow in the morphogenesis of mammalian arteries and veins are not well understood. We examined the development of the dorsal aorta (DA) and the cardinal vein (CV) in Ncx1 -/- mutants, which lack blood flow due to a deficiency in a sodium calcium ion exchanger expressed specifically in the heart. The mutant DA and CV were abnormally connected. The endothelium of the Ncx1 -/- mutant DA lacked normal expression of the arterial markers ephrin-B2 and Connexin-40. Notch1 activation, known to promote arterial specification, was decreased in mutant DA endothelial cells (ECs), which ectopically expressed the venous marker Coup-TFII. These findings suggest that flow has essential functions in the DA by promoting arterial and suppressing venous marker expression. In contrast, flow plays a lesser role in the CV, because expression of arterial-venous markers in CV ECs was not as dramatically affected in Ncx1 -/- mutants. We propose a molecular mechanism by which blood flow mediates DA and CV morphogenesis, by regulating arterial-venous specification of DA ECs to ensure proper separation of the developing DA and CV
Chlamydia trachomatis: Management in Pregnancy
Chlamydia trachomatis is a sexually transmitted disease (STD) commonly diagnosed in pregnancy. C. trachomatis has been linked to several pregnancy complications including premature rupture of membranes (PROM), preterm labor and birth, low birth weight, intrauterine growth retardation, and postpartum endometritis. Infants born to mothers through an infected birth canal are at risk for acquiring C. trachomatis pneumonitis, conjunctivitis, and nasopharyngeal infection. The standard treatment of C. trachomatis in pregnancy is erythromycin. Recently, amoxicillin and clindamycin have been added as alternative regimens for those patients intolerant of erythromycin. This paper reviews the effectiveness and tolerance of the alternative regimens compared with erythromycin and the success of antepartum treatment of chlamydia in preventing the poor pregnancy outcome and neonatal morbidity associated with C. trachomatis
A mechanistic study of the EC′ mechanism – the split wave in cyclic voltammetry and square wave voltammetry
In this paper, a detailed investigation of electrochemical reactions coupled with homogenous chemical steps using cyclic voltammetry (CV) and square wave voltammetry (SWV) was carried out to study the electrocatalytic (EC’) mechanism. In CV, parameters including scan rate, electrode material and redox reactant were investigated while in SWV, parameters including substrate concentrations and frequencies were altered to demonstrate EC’ mechanism. Mechanistic studies focused on the EC’ mechanism using L-cysteine with ferrocenecarboxylic acid and 1,1 ′-ferrocenedicarboxylic acid respectively. Voltammetric responses were recorded and under conditions of high chemical rate constant and low substrate concentration, a split wave was observed in both CV and SWV studies
