Predictors of New Graduate Nurses’ Organizational Commitment During a Nurse Residency Program

Retaining newly graduated nurses is critical for organizations because of the significant cost of turnover. Since commitment to an organization is associated with decreased turnover intent, understanding factors that influence new graduates’ organizational commitment is important. In a sample of nurse residency program participants, predictors of organizational commitment over time were explored. Perceptions of the work environment, particularly job satisfaction and job stress, were found to be most influential. Nurse residency programs provide extended opportunities to model professional role behaviors for new nurses, enhance knowledge development and clinical application, and promote successful integration to the work environment (Bratt, 2009). Despite these benefits, only 21% of new graduates reported having a formal internship or residency program and 6% had no formal orientation (Kovner et al., 2007). In a national survey of registered nurses (RNs) conducted by the Department of Health and Human Services (2010), it was revealed that almost 40% of new graduates plan to leave their current position within 3 years and almost 22% had already changed position or employer. For those new nurses who left their position, most of the reasons (73%) centered on issues related to the characteristics of the workplace, with stressful work environment being cited most frequently, followed by lack of good management and inadequate staffing. Accreditation organizations including the Commission on Collegiate Nursing Education (2008) and the National Council of State Boards of Nursing (2009a) have advocated for the development of transition to practice programs for newly graduated nurses. In addition, the recently released report of the Institute of Medicine (2010) put forth a key recommendation for organizations to provide nurse residency programs for newly licensed nurses. This report also advocates for the need to evaluate the outcomes of these programs, including their influence on patient outcomes and the retention and competency development of new nurses

Perceptions of Professional Practice and Work Environment of New Graduates in a Nurse Residency Program

New nurses continue to face challenging work environments and high expectations for professional competence as they enter practice. Nurse residency programs are gaining prominence as a mechanism to ease new graduates’ transition to practice. This study examined new graduates’ perceptions of their professional practice competence and work environment throughout a yearlong nurse residency program. Employing a repeated measures design, data were collected at baseline, at 6 months, and at 12 months. Results showed that job satisfaction was significantly lowest at 6 months and highest at 12 months. Job stress was found to be lowest at 12 months and organizational commitment was highest at baseline. Of the variables related to professional practice, clinical decision-making was highest at 12 months and quality of nursing performance significantly increased at each measurement point. These data add to the growing evidence supporting the efficacy of nurse residency programs

Design-for-test structure to facilitate test vector application with low performance loss in non-test mode.

A switching based circuit is described which allows application of voltage test vectors to internal nodes of a chip without the problem of backdriving. The new circuit has low impact on the performance of an analogue circuit in terms of loss of bandwidth and allows simple application of analogue test voltages into internal nodes. The circuit described facilitates implementation of the forthcoming IEEE 1149.4 DfT philosophy [1]

Kentucky Law Survey: Environmental Law

Under the rubric of environmental law, this Survey addresses three separate topics: air quality control, water conservation and development, and zoning. In the exploration of these three topics, relevant decisions from the Kentucky courts and the Kentucky Department for Natural Resources and Environmental Protection, as well as opinions from the Kentucky Attorney General, are analyzed

Self-assembling nanoparticles containing dexamethasone as a novel therapy in allergic airways inflammation.

Nanocarriers can deliver a wide variety of drugs, target them to sites of interest, and protect them from degradation and inactivation by the body. They have the capacity to improve drug action and decrease undesirable systemic effects. We have previously developed a well-defined non-toxic PEG-dendritic block telodendrimer for successful delivery of chemotherapeutics agents and, in these studies, we apply this technology for therapeutic development in asthma. In these proof-of-concept experiments, we hypothesized that dexamethasone contained in self-assembling nanoparticles (Dex-NP) and delivered systemically would target the lung and decrease allergic lung inflammation and airways hyper-responsiveness to a greater degree than equivalent doses of dexamethasone (Dex) alone. We found that ovalbumin (Ova)-exposed mice treated with Dex-NP had significantly fewer total cells (2.78 ± 0.44 × 10(5) (n = 18) vs. 5.98 ± 1.3 × 10(5) (n = 13), P<0.05) and eosinophils (1.09 ± 0.28 × 10(5) (n = 18) vs. 2.94 ± 0.6 × 10(5) (n = 12), p<0.05) in the lung lavage than Ova-exposed mice alone. Also, lower levels of the inflammatory cytokines IL-4 (3.43 ± 1.2 (n = 11) vs. 8.56 ± 2.1 (n = 8) pg/ml, p<0.05) and MCP-1 (13.1 ± 3.6 (n = 8) vs. 28.8 ± 8.7 (n = 10) pg/ml, p<0.05) were found in lungs of the Dex-NP compared to control, and they were not lower in the Dex alone group. In addition, respiratory system resistance was lower in the Dex-NP compared to the other Ova-exposed groups suggesting a better therapeutic effect on airways hyperresponsiveness. Taken together, these findings from early-stage drug development studies suggest that the encapsulation and protection of anti-inflammatory agents such as corticosteroids in nanoparticle formulations can improve efficacy. Further development of novel drugs in nanoparticles is warranted to explore potential treatments for chronic inflammatory diseases such as asthma

On Gauge-Invariant Decomposition of Nucleon Spin

We investigate the relation between the known decompositions of the nucleon spin into its constituents, thereby clarifying in what respect they are common and in what respect they are different essentially. The decomposition recently proposed by Chen et al. can be thought of as a nontrivial generalization of the gauge-variant Jaffe-Manohar decomposition so as to meet the gauge-invariance requirement of each term of the decomposition. We however point out that there is another gauge-invariant decomposition of the nucleon spin, which is closer to the Ji decomposition, while allowing the decomposition of the gluon total angular momentum into the spin and orbital parts. After clarifying the reason why the gauge-invariant decomposition of the nucleon spin is not unique, we discuss which decomposition is more preferable from the experimental viewpoint.Comment: The version to appear in Phys. Rev.

Molecular-beam epitaxial growth of a far-infrared transparent electrode for extrinsic Germanium photoconductors

We have evaluated the optical and electrical properties of a far-infrared (IR) transparent electrode for extrinsic germanium (Ge) photoconductors at 4 K, which was fabricated by molecular beam epitaxy (MBE). As a far-IR transparent electrode, an aluminum (Al)-doped Ge layer is formed at well-optimized doping concentration and layer thickness in terms of the three requirements: high far-IR transmittance, low resistivity, and excellent ohmic contact. The Al-doped Ge layer has the far-IR transmittance of >95 % within the wavelength range of 40--200 microns, while low resistivity (~5 ohm-cm) and ohmic contact are ensured at 4 K. We demonstrate the applicability of the MBE technology in fabricating the far-IR transparent electrode satisfying the above requirements.Comment: 18 pages, 7 figures, accepted for publication in the PAS

Nucleon structure from mixed action calculations using 2+1 flavors of asqtad sea and domain wall valence fermions

We present high statistics results for the structure of the nucleon from a mixed-action calculation using 2+1 flavors of asqtad sea and domain wall valence fermions. We perform extrapolations of our data based on different chiral effective field theory schemes and compare our results with available information from phenomenology. We discuss vector and axial form factors of the nucleon, moments of generalized parton distributions, including moments of forward parton distributions, and implications for the decomposition of the nucleon spin.Comment: 68 pages, 47 figures. Main revision points: improved discussion of chiral fits and systematic uncertainties, several minor refinements. Accepted for publication in Phys.Rev.

Nucleon Electromagnetic Form Factors from Lattice QCD using 2+1 Flavor Domain Wall Fermions on Fine Lattices and Chiral Perturbation Theory

We present a high-statistics calculation of nucleon electromagnetic form factors in $N_f=2+1$ lattice QCD using domain wall quarks on fine lattices, to attain a new level of precision in systematic and statistical errors. Our calculations use $32^3 \times 64$ lattices with lattice spacing a=0.084 fm for pion masses of 297, 355, and 403 MeV, and we perform an overdetermined analysis using on the order of 3600 to 7000 measurements to calculate nucleon electric and magnetic form factors up to $Q^2 \approx$ 1.05 GeV$^2$. Results are shown to be consistent with those obtained using valence domain wall quarks with improved staggered sea quarks, and using coarse domain wall lattices. We determine the isovector Dirac radius $r_1^v$, Pauli radius $r_2^v$ and anomalous magnetic moment $\kappa_v$. We also determine connected contributions to the corresponding isoscalar observables. We extrapolate these observables to the physical pion mass using two different formulations of two-flavor chiral effective field theory at one loop: the heavy baryon Small Scale Expansion (SSE) and covariant baryon chiral perturbation theory. The isovector results and the connected contributions to the isoscalar results are compared with experiment, and the need for calculations at smaller pion masses is discussed.Comment: 44 pages, 40 figure
