Coming To

Coming to aims to explore the power of voice and personal narrative in engaging with experiences different from one’s own. The project was triggered by personal analysis and exploration within the genre of personal nonfiction; looking at the way that texts within this field engage with and draw us closer to different cultures, communities, and experiences through authorial presence and strong narrative voice. Coming to attempts to embody these characteristics within a creative piece. It focuses on my experience with a fellow honors student, Daniella Runyambo. Daniella is a student originally from the Democratic Republic of the Congo (DRC). The piece endeavors to capture both of our stories, and primarily the personal change catalyzed within me throughout my time with Daniella

Results on Transversal and Axial Motions of a System of Two Beams Coupled to a Joint through Two Legs

In recent years there has been renewed interest in inflatable-rigidizable space structures because of the efficiency they offer in packaging during boost-to-orbit. However, much research is still needed to better understand dynamic response characteristics, including inherent damping, of truss structures fabricated with these advanced material systems. We present results of an ongoing research related to a model consisting of an assembly of two beams with Kelvin-Voight damping, coupled to a simple joint through two legs. The beams are clamped at one end but at the other end they satisfy a boundary condition given in terms of an ODE coupling boundary terms of both beams, which reflects geometric compatibility conditions. The system is then written as a second order differential equation in an appropriate Hilbert space  in which well-posedness, exponential stability as well as other regularity properties of the solutions can be obtained. Two different finite dimensional approximation schemes for the solutions of the system are presented. Numerical results are presented and comparisons are made.Fil: Burns, J. A..

Program Evaluation of Clark County Department of Family Services, Parenting Project

The Clark County Department of Family Services, Parenting Project, hereinafter referred to as Parenting Project, partnered with the University of Nevada, Las Vegas, School of Environmental and Public Affairs to participate in a program evaluation. The evaluation will serve as a tool to determine the effectiveness of the services delivered to the community by Parenting Project and to aid them in overall program improvement and implementation. This Program Evaluation focuses on two of the six core parenting classes that are currently offered free to the public, more specifically the Nurturing Parents and Families program and the ABC’s of Parenting. The identified programs utilize a pre-posttest inventory known as the Adult / Adolescent Parenting Inventory (AAPI-2). The AAPI-2 measures the risk of abusive parenting behaviors and is collected from each program participant. Data collected from the years 2005 - 2014 were used in the evaluation of the two programs

Vertical distribution of microbial and meiofaunal populations in sediments of a natural coastal hydrocarbon seep

We studied the vertical distribution of microbes and meiofauna in natural hydrocarbon seep sediments to determine if there was a relationship between profiles of benthic trophic structure and the unique biogeochemical conditions present at the seep. Three stations in the Santa Barbara Channel represented a gradient of natural petroleum seepage, from very active, to moderate, to none. Seasonal differences were examined by sampling in the three major oceanographic seasons, upwelling (April), mixed (July), and Davidson (December). Densities of microbes and meiofauna were highest in July, and decreased in winter. All population sizes decreased with increasing depth in the sediment. Harpacticoids and Chl a were practically restricted to the surface sediments. Harpacticoids and Chl a were more dense (number per unit volume or strata of sediment) and abundant (number per unit area of sediment or sum of the strata) at the comparison site than at the seep sites. Density and abundance of nematodes, bacteria cell counts, and bacterial biomass were greater at the station with the most active seepage rates. Bacterial biovolumes appeared constant among sediment depths and stations, but cell biovolumes were larger in July. The data are consistent with the hypothesis that organic enrichment via petroleum utilization is responsible for increased abundances of bacteria and nematodes at the seep. There were strong correlations between densities of harpacticoids and microalgae, and densities of nematodes and bacteria. These links indicate that seeping petroleum might have an enhanced effect on the detrital (bacterial based) food web, but a toxic effect on the grazing (microalgal based) food web

Educating pharmacists on the risks of strong opioids with descriptive and simulated experience risk formats: A randomized controlled trial

Objectives. High opioid prescription rates in the United States and Europe suggest miscalibrated risk perceptions among those who prescribe, dispense, and take opioids. Findings from cognitive decision science suggest that risk perceptions and behaviors can differ depending on whether people learn about risks by experience or description. This study investigated effects of a descriptive versus an experience-based risk education format on pharmacists’ risk perceptions and counseling behavior in the long-term administration of strong opioids to patients with chronic noncancer pain. Methods. In an exploratory, randomized controlled online trial, 300 German pharmacists were randomly assigned to either a descriptive format (fact box) or a simulated experience format (interactive simulation). Primary Outcome Measures. 1) Objective risk perception, 2) subjective risk perception, and 3) intended and 4) actual counseling behavior. Results. Both risk formats significantly improved pharmacists’ objective risk perception, but pharmacists exposed to the fact box estimated the benefit-harm ratio more accurately than those exposed to the simulation. Both formats proved equally effective in adjusting pharmacists’ subjective risk perception toward a better recognition of opioids’ harms; however, pharmacists receiving the simulation showed a greater change in their actual counseling behavior and higher consistency between their intended and actual counseling than pharmacists receiving the fact box. Conclusion. The simulated experience format was less effective than the descriptive format in improving pharmacists’ objective risk perception, equally effective in motivating pharmacists to counsel patients on less risky treatment alternatives and more effective in changing the reported actual counseling behavior. Implications. These exploratory findings provide important insights into the relevance of the description-experience gap for drug safety and raise questions for future research regarding the specific mechanisms at work
