Christian nonconformity by J. H. Yoder and M. L. King
No full textThis Bachelor thesis with the title Christian nonconformity by J. H. Yoder and M. L. King, deals with the specific status of Christian in society. The first part of the thesis is dedicated to the ethical concept of J. H. Yoder and the second part is dedicated to the ethical concept of M. L. King. The final part is attempting to compare both approaches with a focus on nonconformity. In the comparison is persuaded the social aspect in particular and shows the relationship between the society and the Christians according both concepts. The author of the work uses as literal sources particularly the essays and speeches from M. L. King and from the book of J. H. Yodera: The politics of Jesus. Powered by TCPDF (www.tcpdf.org
Hyperfine splitting of [Al VI] 3.66 mu m and the Al isotopic ratio in NGC 6302
No full textThe core of planetary nebula NGC 6302 is filled with high-excitation photoionized gas at low expansion velocities. It represents a unique astrophysical situation in which to search for hyperfine structure (HFS) in coronal emission lines from highly ionized species. HFS is otherwise blended by thermal or velocity broadening. Spectra containing [Al vr] 3.66 mu m P-3(2) <- P-3(1), obtained with Phoenix on Gemini South at resolving powers of up to 75000, resolve the line into five hyperfine components separated by 20-60 km s(-1) as a result of the coupling of the I = 5/2 nuclear spin of Al-27 with the total electronic angular momentum J. The isotope Al-26 has a different nuclear spin of I = 5, and a different HFS, which allows us to place a 3 sigma upper limit on the Al-26/Al-27 abundance ratio of 1/33. We measure the HFS magnetic dipole coupling constants for [Al vr], and provide the first estimates of the electric quadrupole HFS coupling constants obtained through astronomical observations of an atomic transition
The mass of Kepler-93b and the composition of terrestrial planets
No full textKepler-93b is a 1.478 ± 0.019 R ⊕ planet with a 4.7 day period around a bright (V = 10.2), astroseismically characterized host star with a mass of 0.911 ± 0.033 M ☉ and a radius of 0.919 ± 0.011 R ☉. Based on 86 radial velocity observations obtained with the HARPS-N spectrograph on the Telescopio Nazionale Galileo and 32 archival Keck/HIRES observations, we present a precise mass estimate of 4.02 ± 0.68 M ⊕. The corresponding high density of 6.88 ± 1.18 g cm–3 is consistent with a rocky composition of primarily iron and magnesium silicate. We compare Kepler-93b to other dense planets with well-constrained parameters and find that between 1 and 6 M ⊕, all dense planets including the Earth and Venus are well-described by the same fixed ratio of iron to magnesium silicate. There are as of yet no examples of such planets with masses >6 M ⊕. All known planets in this mass regime have lower densities requiring significant fractions of volatiles or H/He gas. We also constrain the mass and period of the outer companion in the Kepler-93 system from the long-term radial velocity trend and archival adaptive optics images. As the sample of dense planets with well-constrained masses and radii continues to grow, we will be able to test whether the fixed compositional model found for the seven dense planets considered in this paper extends to the full population of 1-6 M ⊕ planets.Peer reviewe

Health Status and Access Disparities Among the Uninsured Working-Age Population in a Safety-Net Healthcare Network in Tarrant County, Texas
No full textThe objective of this research was to determine if healthcare access disparities exist across race and gender in a publically funded safety-net healthcare system in Texas. Data were examined from a representative random sample of 1468 adults aged 18-64 who were patients in this safety-net system in July and August of 2000 and were analyzed using binary logistic regression and chi-square measures of significance. Major Findings: On measures of health status - overall health rating (p =.051), limited employment (p =.000), energy level (p =.001), and worry (p =.012) - Anglos reported the worst health; Mexican Americans, the best health; with African Americans intermediate. Mexican Americans were more likely to have never had health insurance, and to also have had insurance in the past year; Anglos were least likely to have ever had insurance (p =.015) or to have had insurance in the past year (p =.000). On use of EDs (p =.028), problems getting prescription medicines (p =.029), and foregoing other necessities of life to pay for healthcare, Mexican Americans were least disadvantaged with African Americans reporting greatest use of EDs among both men and women, and Anglos the most problems with prescription medicines and foregoing care, especially among women. Logistic regression revealed that health status was the strongest predictor of problems accessing healthcare in all groups; the poorer health status of safety-net patients, the more problems they had accessing care. Patterns of poor reported health status and greater problems accessing care among Anglos relative to other groups is discussed in terms of social drift and relative deprivation

Making a market for Miscanthus: Can new contract designs solve the biofuel investment hold-up problem?
No full textWe present designs for optimal contracts to solve the investment hold-up problem for perennial crops for the biofuel industry. A fixed-price contract is ex-ante efficient but renegotiation-proof for a limited range of discount parameters. A perfectly- indexed contract is both renegotiation-proof and ex-post efficient. Provided long-run land prices are stationary, the expected cost for both contracts converges to the long-run expected price of land for a risk-neutral farmer.Biofuels, Miscanthus, contract theory, industrial organization, renegotiation-proof contract, Marketing,
Demonstration of transverse-magnetic deep-ultraviolet stimulated emission from AlGaN multiple-quantum-well lasers grown on a sapphire substrate
No full textWe demonstrate transverse-magnetic (TM) dominant deep-ultraviolet (DUV) stimulated emission from photo-pumped AlGaN multiple-quantum-well lasers grown pseudomorphically on an AlN/sapphire template by means of photoluminescence at room temperature. The TM-dominant stimulated emission was observed at wavelengths of 239, 242, and 243 nm with low thresholds of 280, 250, and 290 kW/cm[superscript 2], respectively. In particular, the lasing wavelength of 239 nm is shorter compared to other reports for AlGaN lasers grown on foreign substrates including sapphire and SiC. The peak wavelength difference between the transverse-electric (TE)-polarized emission and TM-polarized emission was approximately zero for the lasers in this study, indicating the crossover of crystal-field split-off hole and heavy-hole valence bands. The rapid variation of polarization between TE- and TM-dominance versus the change in lasing wavelength from 243 to 249 nm can be attributed to a dramatic change in the TE-to-TM gain coefficient ratio for the sapphire-based DUV lasers in the vicinity of TE-TM switch.Copyright 2015 American Institute of Physics.

Understanding the meaning of nurse practitioner autonomous practice in Oklahoma; A Gadamerian approach
No full textDespite more than 45 years of nurse practitioner (NP) history, the ability of NPs to practice autonomously as primary care providers continues to be influenced by cultural, socioeconomic, and political factors. Relatively little attention, however, has been given to the NP's own understanding of what autonomy means within the context of daily practice. The purpose of this qualitative study was to elicit an understanding of the meaning of autonomy as interpreted by NPs through the lived experiences of their everyday practice in primary health care.
This was a Gadamerian hermeneutic study that also incorporated Gilligan's feminist perspective. Purposive and network sampling were used to ensure that a broad swath of NPs from diverse primary health care practice settings was achieved. Data were collected from nine NPs during individual, face-to-face interviews of one to two hours duration. Each interview was audio-taped and transcribed by the author or a transcriptionist.
Interpretive analysis incorporated Gadamer's hermeneutic model of the hermeneutic circle and development of understanding through the fusion of horizons. Gilligan's theory that the development of one's identity is defined through relationships of responsibility and care molded the context of hermeneutic interpretation. Findings revealed that "Having Genuine NP Practice" was the major theme, reflecting the participant's own overall meaning of his or her autonomy. Practicing independently and alone (in the room) with the patient provided the context within which participants shaped the meaning of Having Genuine NP Practice, including its four sub-themes: (a) relationships, (b) self-reliance, (c) self-empowerment, and (d) defending the NP role.
The participant NPs perceived their practice as autonomous despite a restrictive practice environment. Understanding how NPs in this study shaped Having Genuine NP Practice provided insight into their daily practice, their professional self, the integral part that relationships occupy in the everyday life of being an NP, and daily struggles. This study highlighted the impact of a traditional, hierarchical culture and the social impediments to achieving full autonomy. New knowledge of what Having Genuine NP Practice means enables the NP profession to influence health care reform better
Individuals-area relationships: The relationship between animal population density and area. Ecology
No full textAbstract. We compiled studies that report data on the relationship between animal population density and patch or island area for 287 individual species and 21 faunas. We tested the assumption of the equilibrium theory of island biogeography that population densities are independent of area by performing a meta-analysis using the linear correlation coefficient, r, as a measure of the effect of area on population density. We fit meta-analyses that used a random-effects model to these data to test for the effects of taxa, habitat, latitude, spatial scale, and overall population density. We also fit meta-analyses that used a fixedeffect model to the same data to estimate the repeatability of measurements of the correlation between population density and area within species. Contrary to the equilibrium theory of island biogeography, our results indicate that, on average, animal population densities are positively correlated with area, which suggests that density compensation may be uncommon. This result was found for individual species, but not for faunas. We found taxonomic differences in the correlation between population density and area, with insects and birds having on average large or moderately large positive correlations, respectively, and mammals having correlations near zero.

The Use of Topical Oxygen Therapy to Treat a Calciphylaxis Wound During a Global Pandemic: A Case Report
No full texthttps://kent-islandora.s3.us-east-2.amazonaws.com/node/12481/83395-thumbnail.jpgIntroduction. Calciphylaxis is a rare, highly morbid pathological syndrome of vascular calcification and tissue necrosis. It is predominantly seen in patients with end-stage renal disease (ESRD) on chronic dialysis. There is no definitive standard of care for calciphylaxis, and the overall prognosis for patients, particularly those with ulcerated lesions, is bleak. One important role of wound care clinicians during the COVID-19 pandemic is to ensure that the continuity of care of an at-risk population is maintained while limiting the patient’s potential exposure to the virus. Innovative therapies paired with alternative treatment sites of service are one such method. Case Report. A 56-year-old female with ESRD on at-home peritoneal dialysis (PD) presented to the outpatient wound clinic with a punch biopsy-proven calciphylaxis lesion. Within days, state-wide “shelter-at-home” orders due to the COVID-19 pandemic went into effect. To prevent disruption in care and to minimize risk to the patient, the lesion was treated with bi-weekly self-application of a continuous topical oxygen therapy (cTOT) device paired with weekly telemedicine visits. The wound completely resolved after 9 weeks of topical oxygen therapy with no complications or device malfunctions. Conclusions. This case, to the authors’ knowledge, is the first to document healing in a calciphylaxis wound with the use of cTOT. Topical oxygen therapy may be a beneficial adjunctive therapy in the treatment of wounds caused by calciphylaxis. Finding creative ways to navigate this current health care crisis is essential to help mitigate risk for vulnerable patients with advanced comorbidities.</p
