Student Perceptions of the Clinical Education Environment
This Masters Project surveyed nursing clinical students at a University School of Nursing
in the Pacific Northwest using a recently developed tool, the Student Evaluation of Clinical
Education Environment (SECEE, version 3). Use of the SECEE (version 3) helped identify
differences in student perceptions of various clinical learning environments. Results of nonparametric
statistics were non-significant due to the small sample size; however there appeared
to be consistent preference by students for clinicals at Magnet designated facilities. Additionally,
higher instructor facilitation scores were also noted among students assigned to the university
main campus (n = 31, M = 45.19, SD = 9.39) compared to students assigned to the distance
campus (n = 9, M = 36.89, SD = 20.63). The findings have implications for nursing education,
specifically the potential benefit of student learning at Magnet designated facilities and the
importance of adequate support and engagement between university faculty and students in
distance learning environments
Land Use Change: A Spatial Multinomial Choice Analysis
Urban decentralization and dispersion trends have led to increased conversion of rural lands in many urban peripheries and exurban regions of the U.S. The growth of the exurban areas has outpaced growth in urban and suburban areas, resulting in growth pressures at the urban-rural fringe. A thorough analysis of land use change patterns and the ability to predict these changes are necessary for the effective design of regional environmental, growth, and development policies. We estimate a multinomial discrete choice model with spatial dependence using parcel-level data from Medina County, Ohio. Accounting for spatial dependence should result in improved statistical inference about land use changes. Our spatial model extends the binary choice “linearized logit” model of Klier and McMillen (2008) to a multinomial setting. A small Monte Carlo simulation indicates that this estimator performs reasonably well. Preliminary results suggest that the location of new urban development is guided by a preference over lower density areas, yet in proximity to current urban development. In addition, we find significant evidence of spatial dependence in land use decisions.Land Use Change, Multinomial Logit, Spatial Dependence, Community/Rural/Urban Development, Land Economics/Use, Research Methods/ Statistical Methods, R14, C21, C25,
Reply to Comments of Steuernagel on the Afshar's Experiment
We respond to criticism of our paper "Paradox in Wave-Paricle Duality for
Non-Perturbative Measurements". We disagree with Steuernagel's derivation of
the visibility of the Afshar experiment. To calculate the fringe visibility,
Steuernagel utilizes two different experimental situations, i.e. the wire grid
in the pattern minima and in the pattern maxima. In our assessment, this
proceduere cannot lead to the correct result for the complementarity properties
of wave-particle in one particular experimental set-up
Energetics and Electronic Properties of Interstitial Chlorine in CdTe
Indexación: Scopus.We acknowledge support from Chilean funding agency FONDECYT under Grants No. 1170480 (W.O.) and 1171807 (E.M-P.). Powered@NLHPC: This research was partially supported by the supercomputing infrastructure of the NLHPC (ECM-02).The role of interstitial chlorine in the electronic properties of CdTe is addressed by density functional theory calculations including hybrid functionals and large unit cells. The stability and diffusion energy barriers of the impurity are analyzed as a function of the Fermi level position in the band gap. Chlorine is found to be stable in at least five interstitial sites with rather close formation energies, suggesting that they are all probable to be found. In p-type CdTe, the most stable sites are at the center of a CdTe bond and at a split-interstitial configuration, both acting as shallow donors. Whereas in n-type CdTe, it is found at the tetrahedral site surrounded by Cd hosts, acting as a shallow acceptor. We also find that chlorine can induce a deep acceptor level in the bandgap after binding with three Cd host atoms, which can explain the experimentally observed high resistivity in Cl-doped CdTe. The energy barriers for chlorine diffusion in both p-type and n-type CdTe are also discussed. © 2018 WILEY-VCH Verlag GmbH & Co.

Anomalous optical absorption in a random system with scale-free disorder
We report on an anomalous behavior of the absorption spectrum in a
one-dimensional lattice with long-range-correlated diagonal disorder with a
power-like spectrum in the form S(k) ~ 1/k^A. These type of correlations give
rise to a phase of extended states at the band center, provided A is larger
than a critical value A_c. We show that for A < A_c the absorption spectrum is
single-peaked, while an additional peak arises when A > A_c, signalling the
occurrence of the Anderson transition. The peak is located slightly below the
low-energy mobility edge, providing a unique spectroscopic tool to monitor the
latter. We present qualitative arguments explaining this anomaly.Comment: 4 pages, 4 postscript figures, uses revtex
Deadlock detection of Java Bytecode
This paper presents a technique for deadlock detection of Java programs. The
technique uses typing rules for extracting infinite-state abstract models of
the dependencies among the components of the Java intermediate language -- the
Java bytecode. Models are subsequently analysed by means of an extension of a
solver that we have defined for detecting deadlocks in process calculi. Our
technique is complemented by a prototype verifier that also covers most of the
Java features.Comment: Pre-proceedings paper presented at the 27th International Symposium
