Resolution Of A Racemic Isoleucine Mixture By Using Methyl L-Mandelate, Rani Maharani, Ace Tatang Hidayat, Dadan Sumiarsa, Achmad Zainuddin, Ika Wiani Hidayat

Chimica et Natura Acta

A methyl ester of L-mandelic acid was found to be an effective resolving agent for resolution of commercial DL-isoleucine. The resolution was based on Steglich esterification between methyl L-mandelate and Boc-DL-isoleucine. The two resolved isomers were easily separated by using a conventional flash-column chromatography, giving quantitatively good yields. Unfortunately, the methyl L-mandelate was found to be ineffective to resolve four stereoisomers of Fmoc- isoleucine.

Effect Of Enhanced Patient Education On Patient Satisfaction And 30-Day Readmission Rates After Cardiac Arrhythmia Ablation, Kristin A. Bott

Doctoral Dissertations

Patient satisfaction and 30-day hospital readmission rates are metrics used to assess quality of patient care. Dissatisfied patients pose a high risk of readmission (Boulding, Glickman, Manary, Schulman, Staelin, 2011) and during the vulnerable discharge period, 1 in 7 patients may experience an unavoidable readmission within 30-days post-procedure (Jencks, Williams, &Coleman,2009). Successful patient education programs have been linked to improved patient satisfaction and subsequently reduced unnecessary readmissions (Murdock& Griffin, 2013; Hansen et al., 2011). In an effort to increase satisfaction and reduce readmissions much of the healthcare community’s attention has turned to interventions that have these primary aims. Increased patient …

Factors That Affect Reattempting The Emergency Medical Technician Cognitive Certification Examination, Kim Darlene Mckenna

Dissertations

Certification as an Emergency Medical Technician (EMT) is often the entry point for firefighting careers and is a pre-requisite to enter Advanced EMT or paramedic programs. EMT candidates in most of the United States must pass the National Registry of EMTs cognitive examination (NREMT-C) to be eligible for state licensure. Many candidates who fail their first NREMT-C attempt never take even one of the five additional possible attempts within the specified two-year time frame. Using binary logistic regression with de-identified existing NREMT test data from 2007 though 2012, this research attempted to develop a model to show the relative contribution …

The Public Consequences Of A Personal Choice: The Impact Of The Decision To Be Childfree In Family-Friendly America, Emily Ingalls

Dissertations

The topic of diversity and inclusion has garnered increased interest over the past decade, with 78% of executives listing the topics as critical initiatives (Forbes, 2011). One group that has received little attention but continues to be stigmatized is the childfree population, or those individuals who deliberately choose not to have children. Previous research has examined opinions of this group generally and in the workplace, specifically, but this research frequently considers childfree and childless people under the same umbrella. This study examined ratings of the childfree in the workplace compared to childless adults as well as to parents. The potential …

Impact Of A Growth Mindset Intervention On Academic Performance Of Students At Two Urban High Schools, Lisa Brougham

Dissertations

Urban high school students have greater challenges with respect to retention and graduation rates than their non-urban peers (Farrington et al., 2012). Many academic initiatives have attempted to resolve the problems of retention and poor academic performance with little sustained success. For this study, the empirical literature was reviewed to identify a remedy for poor academic performance that may be implemented by school counselors. Focusing on non-cognitive skills, specifically developing a growth mindset, has shown promising results (Aronson, Fried, & Good, 2002; Blackwell, Trzesniewski, & Dweck, 2007; Yeager & Dweck, 2012). The underlying theoretical framework for this study is Dweck’s …

The Journey Of Individuation: A Jungian Alternative To The Theory And Practice Of Leading Authentically, Dm Ladkin, C Spiller, G Craze

Plymouth Business School

Along with increasing interest in the concept of ‘authenticity’ as it applies to leadership, critique of dominant authentic leadership theorizing is also on the rise. This paper joins that critique in relation to a key aspect of dominant theorizing: its neglect of the unconscious and its role in shaping one’s experience and behaviour. This oversight results in an unrealistic version of ‘authenticity’ which over-emphasizes pro-social, positive conduct, prescribes components through which authenticity is achieved, and directs individuals to act from an individually determined ‘true self’ rather than recognizing the role that both others and the wider context play in the …

Editorial, Aac Abeysinghe, D Kasturiratne

Plymouth Business School

Researching is now flourishing in Sri Lankan universities. Bourgeoning number of annual conferences and faculty journals evidence this. The provision of research funding must have influenced this development. Our brief survey of these journals, however, indicates that 95% of the papers fall in one dominant paradigm - positivism. In contrast, well-ranked international journals publish both positivist and post/anti positivist papers almost equally. This suggests that we need to think of a methodological diversity.
