    Stories of Mothers of Medically Vulnerable Infants

    Get PDF
    As with any new baby, a medically vulnerable infant must be incorporated into the life of the family. The work of this transition is principally the work of the mother as primary caretaker. The mother considers what it will mean to have this infant in the family, how he will fit in, and what things will change. The mother wonders about how his personality will unfold and what his future will bring. She thinks about her role as a mother and how to best meet her child\u27s special needs. With a medically vulnerable infant, a mother also has to consider the implications of health and developmental problems. She has relationships with multiple health care professionals who are now a part of her family\u27s life. The mothers in this study touched upon all of these matters. They seemed to be exploring and grappling with three overarching issues: a) the infant and his future, b) navigating relationships with health care professionals, and c) discovering what it means to be the mother of this child

    Two hundred and sixteen pigs were weaned at 14 or 21 d of age to determine the effect of weaning age and commingling after the nursery phase on growth and behavior of pigs in a wean-tofinish facility. Pigs were divided into older and younger age groups and allotted 12 pigs/pen with nine replications of each group. At the end of the nursery phase (d 34 after weaning), one-half of the pigs in each group were removed and commingled for the grower/finisher phase and the other half remained in their original pens. Beginning at weaning (d 0), pigs were monitored via camera surveillance following weaning, commingling, and on d 65 after weaning. While in the nursery phase, older pigs had greater gain and feed intake than younger pigs, however, younger pigs were more efficient throughout the nursery phase than older pigs. Toward the end of the grower/finisher period, younger pigs had greater gain, feed intake, and gain:feed than older pigs and reached a common weight 4 d sooner. Younger pigs spent more time standing or moving during the nursery phase than older pigs. Immediately following commingling, the younger, unmixed pigs spent more time feeding. However on d 65 after weaning, the older, commingled pigs and younger, unmixed pigs spent more time feeding than older, unmixed pigs and younger, commingled pigs. In conclusion, younger pigs grew slower than older pigs during the nursery phase; however, younger pigs gained more during the finishing period. Additionally, weaning age and commingling influenced feeding behavior during the grower/finisher period

    Something Old, Something New: MBA Program Evaluation Using Shift-Share Analysis and Google Trends

    Get PDF
    Shift-share analysis is a decomposition technique that is commonly used to measure attributes of regional change. In this method, regional change is decomposed into its relevant functional and competitive parts. This paper introduces traditional shift-share method and its extensions with examples of its applicability and usefulness for program evaluation and development, strategic planning, enrollment management and other traditional functions of higher education administration. To illustrate we provide an appraisal of the impact of demographic and employment changes resulting from the great recession on the MBA program of a regional private university in the state of Connecticut. We establish the validity of our shift-share based analysis with a Google Trends examination of relevant keywords

    Enhancement of fast scan cyclic voltammetry detection of dopamine with tryptophanmodified electrodes

    Get PDF
    Fast scan cyclic voltammetry (FSCV) allows for real -time analysis of phasic neurotransmitter levels. Tryptophan (TRP) is an aromatic amino acid responsible for facilitating electron transfer kinetics in oxidoreductase enzymes. Previous work with TRP-modified electrodes showed increased sensitivity for cyclic voltammetry detection of dopamine (DA) when used with slower scan rates (0.05 V/s). Here, we outline an in vitro proof of concept for TRP-modified electrodes in FSCV detection of DA, and decreased sensitivity for ascorbic acid (AA). TRP-modified electrodes had a limit of detection (LOD) for DA of 2.480 ± 0.343 nM compared to 8.348 ± 0.405 nM for an uncoated electrode. Selectivity for DA/ascorbic acid (AA) was 1.107 ± 0.3643 for uncoated and 15.57 ± 4.184 for TRP-modified electrodes. Additionally, these TRP-modified electrodes demonstrated reproducibility when exposed to extended cycling. TRP-modified electrodes will provide an effective modification to increase sensitivity for DA

    Initiating a Research-Focused Academic Career in Chemical Engineering: Perspectives from Faculty at Different Career Stages

    Get PDF
    Each fall, eager young researchers participate in the Meet the Faculty Candidates poster session at the AIChE Annual Meeting, and many more apply to tenure‐track faculty openings at academic institutions across the United States and throughout the world. These individuals embark on this journey with the eventual goal of becoming full professors. The process of initiating an academic career and developing a successful independent research program is an arduous journey that involves multiple stages. These stages include being hired into a faculty position, building an independent research program that involves recruiting students and can include constructing a laboratory, identifying research areas and specific problems to investigate, and establishing oneself as a scientific leader of a particular subject matter area within a broader community. Faculty candidates commonly seek advice from mentors or peers who have recently navigated the faculty interview and hiring processes to successfully obtain an academic position. Additionally, they often review the wealth of resources that are available on the Internet and in print. However, it can be daunting to sieve through this collective knowledge base to identify relevant information, as it invariably contains conflicting viewpoints and advice that may be subjective, generic to any research‐focused faculty position, or highly field specific

    Corona, Jet, and Relativistic Line Models for Suzaku/RXTE/Chandra-HETG Observations of the Cygnus X-1 Hard State

    Get PDF
    Using Suzaku and the Rossi X-ray Timing Explorer, we have conducted a series of four simultaneous observations of the galactic black hole candidate Cyg X-1 in what were historically faint and spectrally hard low states. Additionally, all of these observations occurred near superior conjunction with our line of sight to the X-ray source passing through the dense phases of the focused wind from the mass donating secondary. One of our observations was also simultaneous with observations by the Chandra-High Energy Transmission Grating. These latter spectra are crucial for revealing the ionized absorption due to the secondary's focused wind. Such absorption is present and must be accounted for in all four spectra. These simultaneous data give an unprecedented view of the 0.8-300 keV spectrum of Cyg X-1, and hence bear upon both corona and X-ray emitting jet models of black hole hard states. Three models fit the spectra well: coronae with thermal or mixed thermal/non-thermal electron populations, and jets. All three models require a soft component that we fit with a low temperature disk spectrum with an inner radius of only a few tens of GM/c^2. All three models also agree that the known spectral break at 10\,keV is not solely due to the presence of reflection, but each gives a different underlying explanation for the augmentation of this break. Thus whereas all three models require that there is a relativistically broadened Fe line, the strength and inner radius of such a line is dependent upon the specific model, {thus making premature line-based estimates of the black hole spin in the Cyg X-1 system. We look at the relativistic line in detail, accounting for the narrow Fe emission and ionized absorption detected by HETG. Although the specific relativistic parameters of the line are continuum-dependent, none of the broad line fits allow for an inner disk radius that is >40 GM/c^2.Comment: 22 pages, 16 figures.

    A spatial-temporal analysis of section 404 wetland permitting in Texas and Florida: Thirteen years of impact along the coast

    Get PDF
    Over the past 200 years, an estimated 53% (about 47 million ha) of the original wetlands in the conterminous United States have been lost, mainly as a result of various human activities. Despite the importance of wetlands (particularly along the coast), and a longstanding federal policy framework meant to protect their integrity, the cumulative impact on these natural systems over large areas is poorly understood. We address this lack of research by mapping and conducting descriptive spatial analyses of federal wetland alteration permits (pursuant to section 404 of the Clean Water Act) across 85 watersheds in Florida and coastal Texas from 1991 to 2003. Results show that more than half of the permits issued in both states (60%) fell under the Nationwide permitting category. Permits issued in Texas were typically located outside of urban areas (78%) and outside 100-year floodplains (61%). More than half of permits issued in Florida were within urban areas (57%) and outside of 100-year floodplains (51%). The most affected wetlands types were estuarine in Texas (47%) and palustrine in Florida (55%). We expect that an additional outcome of this work will be an increased awareness of the cumulative depletion of wetlands and loss of ecological services in these urbanized areas, perhaps leading to increased conservation efforts
