    • A Kaleidoscope of Digital American Literature

      Brogan, Martha L.; Rentfrow, Daphnée (Digital Library Federation and Council on Library and Information Resources, 2005-09)
      This report will be useful to anyone interested in the current state of online American literature resources. Its purpose is twofold: to offer a sampling of the types of digital resources currently available or under development in support of American literature; and to identify the prevailing concerns of specialists in the field as expressed during interviews conducted between July 2004 and May 2005. Part two of the report consolidates the results of these interviews with an exploration of resources currently available. Part three examines six categories of digital work in progress: (1) quality-controlled subject gateways, (2) author studies, (3) public domain e-book collections and alternative publishing models, (4) proprietary reference resources and full-text primary source collections, (5) collections by design, and (6) teaching applications. This survey is informed by a selective review of the recent literature. Daphnée Rentfrow assisted in writing and editing the report. This 176 page report is also available from purchase for $30 from CLIR or the DLF. It is freely available in html or pdf formats from their web sites.

    • Kangaroo Care as Analgesic for Preterm Infants Undergoing Heel Sticks

      Hay-Roe, Jillian Veronica (The University of Arizona., 2010-05)
      More than half a million infants are born preterm each year in the United States. Preterm infants often undergo many painful procedures starting minutes after birth. A preterm infant may have as many as 10 painful procedures in a 24 hour period. The experience of pain leads to negative physiological responses, creating additional risks for the preterm infants' immediate and long-term health. Research demonstrates that infants are often undertreated for pain. Kangaroo care is a promising, non-pharmacologic analgesic, implemented as skin-to-skin contact between the infant and a caregiver. The purpose of this paper is to review relevant research about the use of kangaroo care as pain management for preterm infants, and to present a proposal for implementing and evaluating a best practice protocol for kangaroo care as an analgesic in a neonatal intensive care unit.
    • Kangaroo Care, Facilitated Tucking and Non-Nutritive Sucking to Reduce Pain in Neonates: A Best Practice Proposal

      Hartley, Kelsey Alexis (The University of Arizona., 2014)
      Increasing survival rates of preterm infants and a greater understanding of the long-term consequences of prematurity and early exposure to pain have generated a greater need for non-pharmacological pain management measures in the neonatal intensive care unit (NICU) setting. These pain management interventions are necessary to decrease the potentially unfavorable consequences of early exposure to pain, and to promote positive long-term outcomes in this 5 population. The purpose of this thesis was to propose a best practice plan for kangaroo care, facilitated tucking and non-nutritive sucking interventions for infants receiving care in the NICU. Synthesis of available research is presented to support the use of these interventions as methods of non-pharmacological pain management, and to formulate policies for implementation in the hospital setting. Policies included in this paper were specifically developed for use in the NICU at St. Joseph's hospital in Tucson, Arizona. Effectiveness of the aforementioned interventions will be evaluated using an informal written questionnaire, distributed to nurses on the targeted unit.

    • Kartchner Caverns: Habitat Scale Community Diversity and Function in a Carbonate Cave

      Curry, Joan; Ortiz-Ortiz, Marianyoly; Rich, Virginia; Vedantam, Gayatri; Curry, Joan; Maier, Raina M. (The University of Arizona., 2012)
      This dissertation examines the microbial and functional diversity in Kartchner Caverns, a limestone cave in Arizona, USA. Kartchner is highly oligotrophic due to the lack of photosynthesis and the limited inputs of organic material from the surface. This characteristic poses a challenge for microbial life in the cave. The first objective of this work was to evaluate the bacterial richness, diversity and taxonomic composition of speleothems surfaces within Kartchner Caverns in order to gain insight into the distribution patterns associated with these communities. Secondly, the metabolic strategies used by cave communities to survive harsh cave conditions were investigated based on phylogenetic associations and metagenomics. Both objectives were directed toward answering the questions "who are there?" and "what are they doing?". The 454-pyrotag analysis of the V6 region of the 16S rRNA gene revealed an unexpectedly high bacterial diversity with each speleothem supporting a unique bacterial community profile. A focused study on one room of the cave revealed three community types: Type 1 was dominated by the phylum Proteobacteria; Type 2 by Actinobacteria; and Type 3 by Acidobacteria. Phylogenetic associations of the sequences generated by the 454 sequencing and by a Sanger clone library suggested cave microbial communities are supported by chemoautotrophic activities such as nitrite and iron oxidation. Results from the phylogenetic associations guided the metagenomic analysis which supports the presence of chemoautotrophic activities in the cave. Genes for two complete CO2 fixation mechanisms, the Calvin-Benson-Bashan and the rTCA cycles were identified in the cave metagenome, as well as genes for ammonia and nitrite oxidation. These genes are associated with both Bacteria and Archaea suggesting members of both domains are acting as primary producers in the cave ecosystem. Comparative analysis of cave samples to other environments suggests an overabundance of DNA repair mechanisms which could be potentially used by cave communities to overcome the toxicity due to high concentrations of calcium on the speleothem surfaces. This work provides the first comprehensive analysis of the microbial diversity and potential strategies used by microbial communities to survive under the extreme conditions found in a semi-arid limestone cave environment.
    • Karyometry Identifies A Deviant Phenotype In The Fallopian Tube Epithelium Of Postpartum Subjects And Subject At High Risk Of Ovarian Cancer

      Alberts, David S.; Atluri, Sri Sai Swetha (The University of Arizona., 2019)
      With the highest mortality rate of all gynecologic cancers, ovarian cancer is a deadly reproductive malignancy among women. Previous studies have identified the fallopian tube epithelium to be the site of origin for high grade serous ovarian carcinoma. Survival is high when the cancer is discovered while it is still localized to the site of origin, but it is rarely detected that early due to the late manifestation of symptoms and ineffectiveness of current screening methods. Karyometry is a quantitative histopathology technique that detects chromatin abnormalities at the nuclear level using imaging analysis. This study investigates whether karyometry can detect nuclear abnormalities of fallopian tube epithelium in women carrying the BRCA1 or BRCA2 mutation versus the fallopian tube epithelium of women who are at normal risk of developing ovarian cancer. Fallopian tube tissue from 11 women who were at normal risk, 13 women who carried the BRCA1 or BRCA2 mutation, and 13 postpartum women was analyzed using karyometry. There was a distinct deviation in mean nuclear signatures between the normal and high risk groups and between the normal and postpartum groups. In this preliminary analysis, karyometry detected nuclear abnormalities in the fallopian tube epithelium of high risk women.

    • Kenaf Varietal Comparisons at the Safford Agricultural Center, 1996-97

      Clark, L. J.; Carpenter, E. W.; Ottman, Michael J. (College of Agriculture, University of Arizona (Tucson, AZ), 1998-10)
      Growing conditions for Kenaf were not as favorable in 1997 as in 1996 lowering the highest yield to less than 5 tons per acre. The highest yielding variety, C118-92K, was also the highest yielding variety in 1996.
    • Kenaf Varietal Comparisons at the Safford Agricultural Center, 1998

      Clark, L. J.; Carpenter, E. W.; Ottman, Michael J. (College of Agriculture, University of Arizona (Tucson, AZ), 1999-05)
      Cool spring weather delayed planting into mid May reducing the number of heat units available for plant development. A new variety to our testing program produced the highest yield, DRC 96-1 produced 4.58 tons per acre.
