Guiding Preachers in Development of Narrative Skills for Sermon Illustrations

Preachers can and must cultivate storytelling skills. They may find help in a Narration Worksheet charting the essential elements of story: plot, setting, character, point of view, and unity. A Plot Movements Worksheet helps keep the narrative flowing from situation, through stress and searching to solution and a new situation

What Do You Mean “Truth through Personality”? The Phillips Brooks Definition of Preaching in Historical Context

Applying historical-grammatical hermeneutics to the Brooks definition of preaching as truth through personality helps us hear Brooks say that the sum of all truth is Christ. His truth does not stand in indifference to his person as some theologians insisted. By personality Brooks stressed not only the divine person of Christ but also the preacher” character. The contemporary usage of both words, the eight lectures in context, and the colorful history of the 1870” tell the story

Rainbows Around the Throne: Theological Aesthetics in Evangelism to Same-Sex Attracted Men

Cultural barriers and worldview differences between American evangelicalism and the LGBTQ+ movement have historically hindered evangelism to same-sex attracted men. Although recent Christian theologians have offered wisdom for including same-sex attracted believers in the church and for combating prevailing secular worldviews, evangelistic strategies to reach gay unbelievers remain underdeveloped. This thesis identifies five desires common within the population of same-sex attracted men (beauty, friendship, romance, sexuality, and masculinity) and proposes a method of evangelism which targets these desires using theological aesthetics to communicate the beauty of the gospel creatively and compellingly. A focus on aesthetic apologetics, aesthetic community, and aesthetic biblical theology can demonstrate that the God of the Christian gospel is beautiful, satisfying, and worth trusting

The OSIRIS Lens-Amplified Survey (OLAS) I: Dynamical Effects of Stellar Feedback in Low Mass Galaxies at z ~ 2

We introduce the OSIRIS Lens-Amplified Survey (OLAS), a kinematic survey of gravitationally lensed galaxies at cosmic noon taken with Keck adaptive optics. In this paper we present spatially resolved spectroscopy and nebular emission kinematic maps for 17 star forming galaxies with stellar masses 8 < log($M_*$/$M_{\odot}$) < 9.8 and redshifts 1.2 < z < 2.3. OLAS is designed to probe the stellar mass ($M_*$) and specific star formation rate (sSFR) range where simulations suggest that stellar feedback is most effective at driving gaseous outflows that create galaxy-wide potential fluctuations which can generate dark matter cores. We compare our kinematic data with the trend between sSFR, $M_*$ and H$\alpha$ velocity dispersion, $\sigma$, from the Feedback In Realistic Environments (FIRE) simulations. Our observations reveal a correlation between sSFR and sigma at fixed $M_*$ that is similar to the trend predicted by simulations: feedback from star formation drives star-forming gas and newly formed stars into more dispersion dominated orbits. The observed magnitude of this effect is in good agreement with the FIRE simulations, in which feedback alters the central density profiles of low mass galaxies, converting dark matter cusps into cores over time. Our data support the scenario that stellar feedback drives gaseous outflows and potential fluctuations, which in turn drive dark matter core formation in dwarf galaxies.Comment: 9 pages (5 figures) with 9 page appendix (17 figures).

Item Bank Development and Testing of the Perioperative Non-Opioid Modalities (PNOM) Questionnaire: A Pilot Study

Abstract Background: There are validated tools available to identify surgical patients at risk of persistent opioid use, as well as protocols to decrease perioperative opioid use. However, there are no validated tools to assess the barriers and facilitators to using non-opioid modalities for the treatment of perioperative pain. Objective: The purpose of this study was to develop the item bank for a new instrument entitled the Perioperative Non-Opioid Modalities (PNOM) questionnaire and examine its initial psychometric properties. The PNOM was designed to examine the barriers, moderators, and facilitators surrounding the nurse anesthetists\u27 use of non-opioid modalities for the treatment of perioperative pain. Method: A quantitative, survey study design was used in this pilot study of the PNOM questionnaire with a 7-point Likert type scale. Forty-two CRNAs completed the investigator-developed PNOM questionnaire then, subsequently, twenty-two of these CRNA’s completed the PNOM again to determine the stability of their responses using the test/retest reliability procedure. Results: After dissemination of the PNOM questionnaire to a pilot sample of participants and subsequent analysis of responses, results demonstrate that the PNOM questionnaire has been shown to have preliminary reliability and validity as a tool to assess these barriers and facilitators. This was demonstrated by an overall Cronbach’s alpha of 0.737. The final PNOM questionnaire consisted of 39 items that measured barriers and facilitators to CRNAs’ use of non-opioid modalities for the treatment of perioperative pain. After analysis, all 39 items were included in the final PNOM questionnaire. Each item showed satisfactory internal reliability with Cronbach’s alpha greater than 0.70. Conclusion: The validation study of the PNOM questionnaire is now underway to establish its reliability and validity as a clinical tool to examine the knowledge and opinions of CRNAs on the use of non-opioid modalities to curb the opioid epidemic. In its final iteration, it may be used in the assessment of barriers and facilitators to non-opioid modality use and the development of educational and training needs of the anesthesia provider in order to promote the use of non-opioid modalities

Inferences on the Timeline of Reionization at z~8 From the KMOS Lens-Amplified Spectroscopic Survey

Detections and non-detections of Lyman alpha (Ly$\alpha$) emission from $z>6$ galaxies ($<1$ Gyr after the Big Bang) can be used to measure the timeline of cosmic reionization. Of key interest to measuring reionization's mid-stages, but also increasing observational challenge, are observations at z > 7, where Ly$\alpha$ redshifts to near infra-red wavelengths. Here we present a search for z > 7.2 Ly$\alpha$ emission in 53 intrinsically faint Lyman Break Galaxy candidates, gravitationally lensed by massive galaxy clusters, in the KMOS Lens-Amplified Spectroscopic Survey (KLASS). With integration times of ~7-10 hours, we detect no Ly$\alpha$ emission with S/N>5 in our sample. We determine our observations to be 80% complete for 5$\sigma$ spatially and spectrally unresolved emission lines with integrated line flux $>5.7\times10^{-18}$ erg s$^{-1}$ cm$^{-2}$. We define a photometrically selected sub-sample of 29 targets at $z=7.9\pm0.6$, with a median 5$\sigma$ Ly$\alpha$ EW limit of 58A. We perform a Bayesian inference of the average intergalactic medium (IGM) neutral hydrogen fraction using their spectra. Our inference accounts for the wavelength sensitivity and incomplete redshift coverage of our observations, and the photometric redshift probability distribution of each target. These observations, combined with samples from the literature, enable us to place a lower limit on the average IGM neutral hydrogen fraction of $> 0.76 \; (68\%), \; > 0.46 \; (95\%)$ at z ~ 8, providing further evidence of rapid reionization at z~6-8. We show that this is consistent with reionization history models extending the galaxy luminosity function to $M_\textrm{UV} \lesssim -12$, with low ionizing photon escape fractions, $f_\textrm{esc} \lesssim 15\%$.Comment: Accepted for publication in MNRA

HST Grism Observations of a Gravitationally Lensed Redshift 10 Galaxy

We present deep spectroscopic observations of a Lyman-break galaxy candidate (hereafter MACS1149-JD) at $z\sim9.5$ with the $\textit{Hubble}$ Space Telescope ($\textit{HST}$) WFC3/IR grisms. The grism observations were taken at 4 distinct position angles, totaling 34 orbits with the G141 grism, although only 19 of the orbits are relatively uncontaminated along the trace of MACS1149-JD. We fit a 3-parameter ($z$, F160W mag, and Ly$\alpha$ equivalent width) Lyman-break galaxy template to the three least contaminated grism position angles using an MCMC approach. The grism data alone are best fit with a redshift of $z_{\mathrm{grism}}=9.53^{+0.39}_{-0.60}$ ($68\%$ confidence), in good agreement with our photometric estimate of $z_{\mathrm{phot}}=9.51^{+0.06}_{-0.12}$ ($68\%$ confidence). Our analysis rules out Lyman-alpha emission from MACS1149-JD above a $3\sigma$ equivalent width of 21 \AA{}, consistent with a highly neutral IGM. We explore a scenario where the red $\textit{Spitzer}$/IRAC $[3.6] - [4.5]$ color of the galaxy previously pointed out in the literature is due to strong rest-frame optical emission lines from a very young stellar population rather than a 4000 \AA{} break. We find that while this can provide an explanation for the observed IRAC color, it requires a lower redshift ($z\lesssim9.1$), which is less preferred by the $\textit{HST}$ imaging data. The grism data are consistent with both scenarios, indicating that the red IRAC color can still be explained by a 4000 \AA{} break, characteristic of a relatively evolved stellar population. In this interpretation, the photometry indicate that a $340^{+29}_{-35}$ Myr stellar population is already present in this galaxy only $\sim500~\mathrm{Myr}$ after the Big Bang.Comment: Accepted to ApJ.

Prospects for extending the Mass-Metallicity Relation to low mass at high redshift: a case study at z~1

We report J-band MOSFIRE spectroscopy of a low-mass (log$(M_*/M_\odot)=8.62^{+0.10}_{-0.06}$) star-forming galaxy at $z=0.997$ showing the detection of [NII] and [SII] alongside a strong H$\alpha$ line. We derive a gas-phase metallicity of log$(\text{O}/\text{H})=7.99^{+0.13}_{-0.23}$, placing this object in a region of $M_* - Z$ space that is sparsely populated at this redshift. Furthermore, many existing metallicity measurements in this $M_* - z$ regime are derived from only [NII]/H$\alpha$ (N2), a diagnostic widely used in high-redshift metallicity studies despite the known strong degeneracy with the ionization parameter and resulting large systematic uncertainty. We demonstrate that even in a regime where [NII] and [SII] are at the detection limit and the measurement uncertainty associated with the [NII]/[SII] ratio is high (S/N~3), the more sophisticated Dopita et al. diagnostic provides an improved constraint compared to N2 by reducing the systematic uncertainty due to the ionization parameter. This approach does not, however, dispel uncertainty associated with stochastic or systematic variations in the nitrogen-to-oxygen abundance ratio. While this approach improves upon N2, future progress in extending metallicity studies into this low-mass regime will require larger samples to allow for stochastic variations, as well as careful consideration of the global trends among dwarf galaxies in all physical parameters, not just metallicity.Comment: 11 pages, 3 figure
