Christian nonconformity by J. H. Yoder and M. L. King
Get PDFThis 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
Get PDFThe 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
Long Term Versus Temporary Certified Emission Reductions in Forest Carbon-Sequestration Programs
Get PDFUnder the Clean Development Mechanism (CDM) of the Kyoto Protocol, forest projects can receive returns for carbon sequestration via two credit instruments: temporary (tCERs) or long-term certified emission reductions (lCERs). This article develops a theoretical model of optimal harvesting strategies that compares private optimal harvest decision under these two instruments. We find that risk neutral landowners are likely to prefer instituting lCERs over tCERs to maximize surplus. A particular type of early harvest penalty implemented under the lCERs is critical in determining the length of rotation intervals and the carbon credit supply. When this penalty is an increasing function of the difference in biomass before and after harvesting across verification periods, the landowner may choose longer or shorter rotation intervals compared to the Faustmann rotation. The resulting supply curve may have a backward bending region over a range of carbon prices.forest rotation, long term certified emission reductions (lCERs), carbon sequestration

A comparative study of Tam3 and Ac transposition in transgenic tobacco and petunia plants
Get PDFTransposition of the Anthirrinum majus Tam3 element and the Zea mays Ac element has been monitored in petunia and tobacco plants. Plant vectors were constructed with the transposable elements cloned into the leader sequence of a marker gene. Agrobacterium tumefaciens-mediated leaf disc transformation was used to introduce the transposable element constructs into plant cells. In transgenic plants, excision of the transposable element restores gene expression and results in a clearly distinguishable phenotype. Based on restored expression of the hygromycin phosphotransferase II (HPTII) gene, we established that Tam3 excises in 30% of the transformed petunia plants and in 60% of the transformed tobacco plants. Ac excises from the HPTII gene with comparable frequencies (30%) in both plant species. When the β-glucuronidase (GUS) gene was used to detect transposition of Tam3, a significantly lower excision frequency (13%) was found in both plant species. It could be shown that deletion of parts of the transposable elements Tam3 and Ac, removing either one of the terminal inverted repeats (TIR) or part of the presumptive transposase coding region, abolished the excision from the marker genes. This demonstrates that excision of the transposable element Tam3 in heterologous plant species, as documented for the autonomous element Ac, also depends on both properties. Southern blot hybridization shows the expected excision pattern and the reintegration of Tam3 and Ac elements into the genome of tobacco plants.
Making a market for Miscanthus: Can new contract designs solve the biofuel investment hold-up problem?
Get PDFWe 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
Get PDFWe 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
Mining housekeeping genes with a Naive Bayes classifier
Get PDFThe first author was supported by the Student Awards Agency for Scotland. The second author is supported by BBSRC grant BBS RC BB/D006473/1, and under the Advanced Knowledge Technologies (AKT) Interdisciplinary Research Collaboration (IRC), which is sponsored by the UK Engineering and Physical Sciences Research Council under grant number GR/N15764/01.Background: Traditionally, housekeeping and tissue specific genes have been classified using direct assay of mRNA presence across different tissues, but these experiments are costly and the results not easy to compare and reproduce. Results: In this work, a Naive Bayes classifier based only on physical and functional characteristics of genes already available in databases, like exon length and measures of chromatin compactness, has achieved a 97% success rate in classification of human housekeeping genes ( 93% for mouse and 90% for fruit fly). Conclusion: The newly obtained lists of housekeeping and tissue specific genes adhere to the expected functions and tissue expression patterns for the two classes. Overall, the classifier shows promise, and in the future additional attributes might be included to improve its discriminating power.Peer reviewe
