Entrepreneurial Orientation As A Basis For Classification Within A Service Industry: The Case Of Retail Pharmacy Industry, Thanigavelan Jambulingam, Ravi Kathuria, William R. Doucette

Business Faculty Articles and Research

To date, service classification research has primarily taken a macro view, creating service typologies or taxonomies by using dimensions such as customer contact or degree of labor intensity. Such classification schemes, though helpful in deciphering critical management issues and positioning strategies between service industries, tend to treat an entire industry, such as airlines, as a single homogenous entity. However, organizations in the same industry often use intangible resources, such as entrepreneurial orientation processes, to compete with one another. Resource-advantage theory suggests that organizations utilize intangible resources to build long-term strategies and a sustainable competitive advantage leading to superior performance. We …

Gaining Compliance And Losing Weight: The Role Of The Service Provider In Health Care Services, Stephanie Dellande, Mary C. Gilly, John L. Graham

Business Faculty Articles and Research

This research provides and empirically tests a conceptualization of health care services in which customer compliance outside of the service organization is necessary for successful health outcomes. Using data from service providers and customers in a weight-loss clinic, the authors examine the provider's role in gaining customer compliance. They find that provider expertise and attitudinal homophily play a role in bringing about customer role clarity, ability, and motivation. This study demonstrates that compliance leads to goal attainment, which results in satisfaction. More important, compliance also leads to satisfaction directly; consumers who comply with program requirements have greater satisfaction with the …

Synthesis Of Nanocrystalline Nickel-Zinc Ferrites Via A Microemulsion Route, Vuk Uskoković, Miha Drofenik

Pharmacy Faculty Articles and Research

Nanostructured NiZn-ferrites were synthesized using a low-temperature co-precipitation method within the reverse micelles of ternary CTAB/1-hexanol/water microemulsions. The influence of pH on the precipitation reaction was investigated. It was found that a higher pH resulted in more crystalline particles. Subsequent oxidation of the ferrous ions precipitate, which leads to the formation of spinel ferrites, is discussed. Diffraction-lines broadening and specific surface area measurements yielded an average particle size of ~ 3 nm. The saturation magnetization of the samples was 20 times smaller than for traditionally synthesized NiZn-ferrites, while the coercivities were 10 - 100 times larger than bulk NiZn-ferrites, which …

Photoreactive Bicyclic Amino Acids As Substrates For Mutant Escherichia Coli Phenylalanyl-Trna Synthetases, Thomas Bentin, Ramin Hamzavi, Jahan Salomonsson, Hervé Roy, Michael Ibba, Peter E. Nielsen

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Unnatural amino acids carrying reactive groups that can be selectively activated under non-invasive biologically benign conditions are of interest in protein engineering as biological tools for the analysis of protein-protein and protein-nucleic acids interactions. The double ring system phenylalanine analogues benzofuranylalanine and benzotriazolylalanine were synthesized, and their photolability was tested by UV irradiation at 254, 320, and 365 nm. Although both showed photo reactivity, benzofuranylalanine appeared as the most promising compound because this amino acid was activated by UVA (long wavelength) irradiation. These amino acids were also tested for in vitro charging of tRNA^Phe and for protein mutagenesis via …

Divergence In Non-Cognate Amino Acid Recognition Between Class I And Class Ii Lysyl-Trna Synthetases, Jeffrey D. Levengood, Sandro F. Ataide, Hervé Roy, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Lysine insertion during coded protein synthesis requires lysyl-tRNA^Lys, which is synthesized by lysyl-tRNA synthetase (LysRS). Two unrelated forms of LysRS are known: LysRS2, which is found in eukaryotes, most bacteria, and a few archaea, and LysRS1, which is found in most archaea and a few bacteria. To compare amino acid recognition between the two forms of LysRS, the effects of l-lysine analogues on aminoacylation were investigated. Both enzymes showed stereospecificity toward the l-enantiomer of lysine and discriminated against noncognate amino acids with different R-groups (arginine, ornithine). Lysine analogues containing substitutions at other positions were generally most effective as …

Speech-Language Pathologists' Opinions On Communication Disorders And Violence, Dixie Sanger, Barbara J. Moore-Brown, Judith Montgomery, Susan Hellerich

Communication Sciences and Disorders Faculty Articles and Research

Purpose: This study investigated the opinions of speech-language pathologists (SLPs) regarding their role, education, and training in serving students with communication disorders who have been involved in violence.

Method: A survey consisting of 26 items was given to 598 SLPs from eight states representing geographic regions of the United States.

Results: Participants acknowledged that violence is an increasing concern. They also recognized the valuable role they have in planning prevention programs and serving on multidisciplinary teams. In contrast, SLPs' opinions suggested that they did not feel well trained to deal with violence, nor did they feel that …

Aminoacyl-Trnas: Setting The Limits Of The Genetic Code, Michael Ibba, Dieter Söll

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aminoacyl-tRNAs (aa-tRNAs) are simple molecules with a single purpose—to serve as substrates for translation. They consist of mature tRNAs to which an amino acid has been esterified at the 3′-end. The 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases (aaRSs, of which there are two classes), one for each amino acid of the genetic code (Ibba and Söll 2000). This would be fine if it were not for the fact that such a straightforward textbook scenario is not true in a single known living organism. aa-tRNAs lie at the heart of gene expression; they interpret …

Nitric Oxide Inhibition Of Adenylyl Cyclase Type 6 Activity Is Dependent Upon Lipid Rafts And Caveolin Signaling Complexes, Rennolds S. Ostrom, Richard A. Bundey, Paul A. Insel

Pharmacy Faculty Articles and Research

Several cell types, including cardiac myocytes and vascular endothelial cells, produce nitric oxide (NO) via both constitutive and inducible isoforms of NO synthase. NO attenuates cardiac contractility and contributes to contractile dysfunction in heart failure, although the precise molecular mechanisms for these effects are poorly defined. Adenylyl cyclase (AC) isoforms type 5 and 6, which are preferentially expressed in cardiac myocytes, may be inhibited via a direct nitrosylation by NO. Because endothelial NO synthase (eNOS and NOS3), β-adrenergic ( AR) receptors, and AC6 all can localize in lipid raft/caveolin-rich microdomains, we sought to understand the role of lipid rafts in …

Hepatitis B Vaccination For Patients With Chronic Renal Failure, Robert J. Schroth, Carol A. Hitchon, Julia Uhanova, Ayman M. Noreddin, Shayne P. Taback, Michael Moffatt, James M. Zacharias

Pharmacy Faculty Articles and Research

Background Chronic renal failure patients are at particular risk of hepatitis B virus infection. Early studies have demonstrated that renal failure patients benefit from vaccination; however, not all studies have consistently shown benefit.

Objectives To determine the beneficial and harmful effects of hepatitis B vaccine and of a reinforced vaccination series in chronic renal failure patients.

Search methods We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Renal Group Controlled Trials Register, The Cochrane Controlled Trials Register on The Cochrane Library (Issue 1, 2002), PubMed/MEDLINE (1966 to July 2003), EMBASE (1985 toNovember 2003), Current Clinical Practice Guidelines (Canadian …

Non-Prescription And Household Substances Of Abuse, J. Mallari, L. Nguyen, Jeffery A. Goad

Pharmacy Faculty Articles and Research

"Reasons for abuse of [household products and over-the-counter (OTC) medications] can vary widely depending on the type of product used. Because these items can be readily found in pharmacies and stores, it is important for pharmacists to become familiar with the signs and symptoms of abuse, and street names by which these agents are known (see Table 1). Pharmacists, especially in the community setting, may be able to identify patterns of abuse since they are in contact with patients more frequently than other healthcare providers."

The Evolving Role Of Lipid Rafts And Caveolae In G Protein-Coupled Receptor Signaling: Implications For Molecular Pharmacology, Rennolds S. Ostrom, Paul A. Insel

Pharmacy Faculty Articles and Research

The many components of G-protein-coupled receptor (GPCR) signal transduction provide cells with numerous combinations with which to customize their responses to hormones, neurotransmitters, and pharmacologic agonists. GPCRs function as guanine nucleotide exchange factors for heterotrimeric (α, β, γ) G proteins, thereby promoting exchange of GTP for GDP and, in turn, the activation of ‘downstream’ signaling components. Recent data indicate that individual cells express mRNA for perhaps over 100 different GPCRs (out of a total of nearly a thousand GPCR genes), several different combinations of G-protein subunits, multiple regulators of G-protein signaling proteins (which function as GTPase activating proteins), and various …

Hepatic Disposition Of Cyclosporine A In Isolated Perfused Rat Livers, Reza Mehvar, Anjaneya Chimalakonda

Pharmacy Faculty Articles and Research

PURPOSE. To develop an isolated perfused rat liver model to study the hepatic disposition of cyclosporine A (CyA) in both sexes.

METHODS. Livers were isolated from male (n = 6) and female (n = 7) rats and perfused with a physiological buffer in a single-pass manner. A bolus 1-mg dose of CyA was injected into the inlet catheter and periodical samples (0-15 min) were collected from the outlet perfusate. The concentrations of CyA in the outlet perfusate, collected bile (0-15 min), and liver tissue (at the end of perfusion) were quantitated by HPLC and subjected to statistical moment analysis. …
