School Nurse Communication Tool and Efficiency in the High School Setting

Approved May 2020 by the faculty of UMKC in partial fulfillment of the requirements for the degree of Doctor of Nursing PracticeIn a high school health room, the school nurse will see a diverse population of students with conditions ranging from chapped lips to difficulty breathing. The school nurse must possess the ability to efficiently, and accurately understand the presenting problem, past medical history, and medications to quickly return the student to the classroom where academic learning will resume. The purpose of the quasi-experimental, quality improvement, retrospective study was to determine if the use of a school nurse communication tool over a 16 week semester decreased the time in minutes that the high school student was in the health room in a public suburban high school setting. The participants were the high school students that presented to the health room at a public high school within a suburban Midwest city. The sample size was 1475 students. Using the seven-item communication tool, time spent in the health room by high school students was measured at baseline and intervention. The use of the communication tool did not significantly decrease the time in minutes the student was in the health room. The tool served as a guide for the school nurse to provide compassionate care in a safe environment such that the student was returned to class while empowered to make healthy behavior choices based upon health promotion education

Linguistic politeness across Austria and Italy: Backing out of an invitation with an instant message

The study compares how native speakers of German from the area of Innsbruck (Austria) and native speakers of Italian from the area of Rome (Italy) perceive the communicative act of backing out of an invitation for dinner at the last minute, in a situation of low social distance. The purpose of the study is twofold: to shed light on the orientation of Austrian German and Italian languages/cultures in terms of linguistic politeness, and to expand empirical cross-cultural research to a less-commonly investigated speech act. Data collected by means of a discourse completion task (DCT) are triangulated with responses to an assessment question and metapragmatic comments, and analyzed following a quantitative approach. The analysis of the DCT findings shows some cross-group differences in the choice of speech act realization strategies and internal modifiers. However, the overall results reveal more similarities than differences between the two populations regarding the informants’ perception of face threat in last-minute cancellations. This seems to disprove the idea that the two groups belong to different cultural frameworks in terms of politeness orientation, at least as far as it concerns the specific speech act under investigation

Band-theoretical prediction of magnetic anisotropy in uranium monochalcogenides

Magnetic anisotropy of uranium monochalcogenides, US, USe and UTe, is studied by means of fully-relativistic spin-polarized band structure calculations within the local spin-density approximation. It is found that the size of the magnetic anisotropy is fairly large (about 10 meV/unit formula), which is comparable with experiment. This strong anisotropy is discussed in view of a pseudo-gap formation, of which crucial ingredients are the exchange splitting of U 5f states and their hybridization with chalcogen p states (f-p hybridization). An anomalous trend in the anisotropy is found in the series (US>>USe<UTe) and interpreted in terms of competition between localization of the U 5f states and the f-p hybridization. It is the spin-orbit interaction on the chalcogen p states that plays an essential role in enlarging the strength of the f-p hybridization in UTe, leading to an anomalous systematic trend in the magnetic anisotropy.Comment: 4 pages, 5 figure

Advances in the Direct Study of Carbon Burning in Massive Stars

The C12+C12 fusion reaction plays a critical role in the evolution of massive stars and also strongly impacts various explosive astrophysical scenarios. The presence of resonances in this reaction at energies around and below the Coulomb barrier makes it impossible to carry out a simple extrapolation down to the Gamow window-the energy regime relevant to carbon burning in massive stars. The C12+C12 system forms a unique laboratory for challenging the contemporary picture of deep sub-barrier fusion (possible sub-barrier hindrance) and its interplay with nuclear structure (sub-barrier resonances). Here, we show that direct measurements of the C12+C12 fusion cross section may be made into the Gamow window using an advanced particle-gamma coincidence technique. The sensitivity of this technique effectively removes ambiguities in existing measurements made with gamma ray or charged-particle detection alone. The present cross-section data span over 8 orders of magnitude and support the fusion-hindrance model at deep sub-barrier energies

Excited State Lifetime Measurements in Rare Earth Nuclei with Fast Electronics

We investigated the collectivity of the lowest excited 2⁺ states of even-even rare earth nuclei. The B(E2) excitation strengths of these nuclei should directly correlate to the size of the valence space, and maximize at mid-shell. The previously identified saturation of B(E2) strength in well-deformed rotors at mid-shell is put to a high precision test in this series of measurements. Lifetimes of the 2⁺1 states in ¹⁶⁸Hf and ¹⁷⁴W have been measured using the newly developed LaBr₃ scintillation detectors. The excellent energy resolution in conjunction with superb time properties of the new material allows for reliable handling of background, which is a source of systematic error in such experiments. Preliminary lifetime values are obtained and discussed in the context of previous and ongoing work

Octupole states in Tl-207 studied through beta decay

The beta decay of Hg-207 into the single-proton-hole nucleus Tl-207 has been studied through gamma-ray spectroscopy at the ISOLDE Decay Station (IDS) with the aim of identifying states resulting from coupling of the pi s(1/2)(-1), pi d(3/2)(-1) and pi h(11/2)(-1) shell model orbitals to the collective octupole vibration. Twenty-two states were observed lying between 2.6 and 4.0 MeV, eleven of which were observed for the first time, and 78 new transitions were placed. Two octupole states (s(3/2)-coupled) are identified and three more states (d(3/2)-coupled) are tentatively assigned using spin-parity inferences, while further h(11/2)-coupled states may also have been observed for the first time. Comparisons are made with state-of-the-art large-scale shell model calculations and previous observations made in this region, and systematic underestimation of the energy of the octupole vibrational states is noted. We suggest that in order to resolve the difference in predicted energies for collective and noncollective t = 1 states (t is the number of nucleons breaking the Pb-208 core), the effect of t = 2 mixing may be reduced for octupole-coupled states. The inclusion of mixing with t = 0, 2, 3 excitations is necessary to replicate all t = 1 state energies accurately.Peer reviewe

Do nuclei go pear-shaped? Coulomb excitation of Rn-220 and Ra-224 at REX-ISOLDE (CERN)

Volume: 93The IS475 collaboration conducted Coulomb-excitation experiments with post-accelerated radioactive Rn-220 and Ra-224 beams at the REX-ISOLDE facility. The beam particles (E-beam: 2.83 MeV/u) were Coulomb excited using Ni-60, Cd-14, and Sn-120 scattering targets. De-excitation gamma-rays were detected employing the Miniball array and scattered particles were detected in a silicon detector. Exploiting the Coulomb-excitation code GOSIA for each nucleus several matrix elements could be obtained from the measured gamma-ray yields. The extracted matrix element allows for the conclusion that, while Rn-220 represents an octupole vibrational system, Ra-224 has already substantial octupole correlations in its ground state. This finding has i(m)plications for the search of CP-violating Schiff moments in the atomic systems of the adjacent odd-mass nuclei.Peer reviewe

Competition between Allowed and First-Forbidden beta Decay : The Case of Hg-208 -> Tl-2(0)8

The beta decay of Hg-208 into the one-proton hole, one neutron-particle Tl-208(81)127 nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N > 126, Z 0(-)beta decay where the daughter state is core excited is unique, and can provide information on mesonic corrections of effective operators.Peer reviewe
