A brief intervention to improve emotion-focused communication between newly licensed pediatric nurses and parents

Indiana University-Purdue University Indianapolis (IUPUI)Parents have increasingly participated in their children’s bedside care. Parental participation has led to more provider-parent interactions and communication during such stressful events. Helping parents through such stressful events requires nurses to be skilled communicators. Brief methods of training emotion-focused communication with newly licensed nurses are needed, but as yet are rare. The purpose of this study was to evaluate the impact of a validated brief communication (Four Habits Model) training program for newly licensed pediatric nurses. The intervention focused on ways to improve nurses’ emotion-focused conversations with parents. Information processing and Benner’s novice to expert informed this study. The intervention is based on the four habits model, with “habits” providing a structure for nurses to organize their thinking and behavior during emotion-focused conversations with parents. Thirty-five pediatric nurses with 0–24 months of nursing experience at a large mid-western children’s hospital participated in the study. Mixed methods provided data for this experimental study, using a group-by-trials repeated measures ANOVA design. Participants randomized to the intervention group participated in a one-hour three-part training: adapted four habits model content, simulated nurse-parent communication activity, and debrief. Participants randomized to the control group observed a one-hour travel video. Key outcome variables were Preparation, Communication Skills, Relationships, Confidence, Anxiety, and Total Preparation. Compared with the controls, the intervention group improved significantly in the following areas: Preparation, F(1,33) = 28.833, p < .001; Communication Skills, F(1,33) = 9.726, p = .004; Relationships, F(1,33) = 8.337, p = .007; Confidence, F(1,33) = 36.097, p < .001; and Total Preparation, F(1,33) = 47.610, p < .001. Nurses’ experience level had no effect, with the exception of Anxiety. Nurses with more experience (≥ 12 m) showed a greater reduction in Anxiety, when compared to nurses with less experience (< 12 m), F(1,31) = 5.733, p = .023. Fifty-two percent of the nurses involved in the intervention later reported specific examples of implementing the four habits when working with parents in clinical settings. A one-hour four habits communication-training program is effective in improving newly licensed nurses’ preparation for emotion-focused conversations with parents

UNDERSTANDING TECHNOLOGY ADOPTION THROUGH SYSTEM DYNAMICS MODELING: IMPLICATIONS FOR AGRIBUSINESS MANAGEMENT

This work demonstrates the utility of sophisticated simulation tools in aiding agribusiness managers' decision making. The system dynamics model developed here provides insight into the use of such models to evaluate potential adoption rates and diffusion patterns of yield mapping and monitoring technologies. The model allows for comparative analyses of the possible effects of different profit assumptions on adoption and diffusion.Agribusiness, Research and Development/Tech Change/Emerging Technologies,

Swelling and shrinking kinetics of a lamellar gel phase

We investigate the swelling and shrinking of L_beta lamellar gel phases composed of surfactant and fatty alcohol after contact with aqueous poly(ethylene-glycol) solutions. The height change $\Delta h(t)$ is diffusion-like with a swelling coefficient, S: $\Delta h = S \sqrt{t}$. On increasing polymer concentration we observe sequentially slower swelling, absence of swelling, and finally shrinking of the lamellar phase. This behavior is summarized in a non-equilibrium diagram and the composition dependence of S quantitatively described by a generic model. We find a diffusion coefficient, the only free parameter, consistent with previous measurements.Comment: 3 pages, 4 figures to appear in Applied Physics Letter

Radio Galaxy Clustering at z~0.3

Radio galaxies are uniquely useful as probes of large-scale structure as their uniform identification with giant elliptical galaxies out to high redshift means that the evolution of their bias factor can be predicted. As the initial stage in a project to study large-scale structure with radio galaxies we have performed a small redshift survey, selecting 29 radio galaxies in the range 0.19<z<0.45 from a contiguous 40 square degree area of sky. We detect significant clustering within this sample. The amplitude of the two-point correlation function we measure is consistent with no evolution from the local (z<0.1) value. This is as expected in a model in which radio galaxy hosts form at high redshift and thereafter obey a continuity equation, although the signal:noise of the detection is too low to rule out other models. Larger surveys out to z~1 should reveal the structures of superclusters at intermediate redshifts and strongly constrain models for the evolution of large-scale structure.Comment: 7 pages, 3 figures, accepted by ApJ Letter

Measurement of ligand coverage on cadmium selenide nanocrystals and its influence on dielectric dependent photoluminescence intermittency

Photoluminescent quantum dots are used in a range of applications that exploit the unique size tuneable emission, light harvesting and quantum efficient properties of these semiconductor nanocrystals. However, optical instabilities such as photoluminescence intermittency, the stochastic switching between bright, emitting states and dark states, can hinder quantum dot performance. Correlations between this blinking of emission and the dielectric properties of the nanoenvironment between the quantum dot interface and host medium, suggest surface ligands play a role in modulating on-off switching rates. Here we elucidate the nature of the cadmium selenide nanocrystal surface, by combining magic angle spinning NMR and x-ray photoelectron spectroscopy to determine ligand surface densities, with molecular dynamics simulation to assess net ligand filling at the nanocrystal interface. Results support a high ligand coverage and are consistent with photoluminescence intermittency measurements that indicate a dominant contribution from surface ligand to the dielectric properties of the local quantum dot environment

Salt grains in hypervelocity impacts in the laboratory: Methods to sample plumes from the ice worlds Enceladus and Europa

The plumes naturally erupting from the icy satellite Enceladus were sampled by the Cassini spacecraft in high-speed fly-bys, which gave evidence of salt. This raises the question of how salt behaves under high-speed impact, and how it can best be sampled in future missions to such plumes. We present the results of 35 impacts onto aluminum targets by a variety of salts (NaCl, NaHCO3, MgSO4, and MgSO4·7H2O) at speeds from 0.26 to 7.3 km s−1. Using SEM-EDX, identifiable projectile residue was found in craters at all speeds. It was possible to distinguish NaCl and NaHCO3 from each other, and from the magnesium sulfates, but not to separate the hydrous from anhydrous magnesium sulfates. Raman spectroscopy on the magnesium sulfates and NaHCO3 residues failed to find a signal at low impact speeds (<0.5 km s−1) where there was insufficient projectile material deposited at the impact sites. At intermediate speeds (0.5 to 2–3 km s−1), identifiable Raman spectra were found in the impact craters, but not at higher impact speeds, indicating a loss of structure during the high speed impacts. Thus, intact capture of identifiable salt residues on solid metal surfaces requires impact speeds between 0.75 and 2 km s−1
