Retention Of Administrators In Nursing Homes: What Can Management Do?, Douglas A. Singh, Robert C. Schwab

Faculty Publications

Annual turnover among nursing home administrators may be 40% or higher. To investigate the factors that could lead to greater administrator retention, responses to a survey (53% response rate) were analyzed using factor analysis and multiple regression models. Results show that higher retention is observed when administrators are allowed to function independently, are involved in decision making, are treated fairly, and are given reasonable goals to achieve. Organizations must hire administrators whose values match theirs. Multifacility chain organizations and for-profit facilities appear to have a greater need to embrace organizational principles that lead to greater job satisfaction.

Electro-Deposition Of Polymer Chains On An Adsorbing Wall: Density Profiles And Wall Coverage, Grace M. Foo, Ras B. Pandey

Faculty Publications

Growth of polymer density in an electro-deposition model of polymer chains on an impenetrable wall is studied on a two dimensional discrete lattice using a Monte Carlo simulation. Polymer-polymer repulsion and polymer-wall attraction for the adsorbing wall (along with the neutral and repulsive interactions) are considered in an external field. Effects of the field strength (B), temperature (T), and chain length (L-c) on the density profile of the polymer chains and wall coverage are investigated. The spatial density profile shows onset of oscillation near the wall at a characteristic field (B-c) which depends on chain length and temperature, In low …

Unfolding Of The Period-Two Bifurcation In A Fiber Laser Pumped With Two Modulation Tones, Scott Glasgow, T. C. Newell, A. Gavrielides, V. Kovanis, D. Sukow, T. Erneux

Faculty Publications

The effect of a small second frequency component on a pump modulated neodymium fiber laser is investigated experimentally and theoretically. This term, whose frequency is exactly half the primary driver, incites an unfolding of the attractor. It breaks the period two pitchfork bifurcation and splits the period one orbit. The modification of the bifurcation diagram is studied analytically by employing a map derived from the class B laser rate equations. We determine specific conditions and scaling laws for this phenomenon. Our analytical predictions are in good agreement with recorded experimental data.

Faculty Publications

Using the ZEUS detector at HERA, we have searched for heavy excited states of electrons, neutrinos, and quarks in e+p collisions at a center-of-mass energy of 300 GeV. With an integrated luminosity of 9.4 pb-1, no evidence was found for electroweak production and decay of such states. Limits on the production cross section times branching ratio and on the characteristic couplings, f/Λ, are derived for masses up to 250 GeV. For the particular choice f/Λ = 1/Mf*, we exclude at the 95% confidence level excited electrons with mass between 30 and 200 GeV, excited electron neutrinos with mass between 40 …

The L3 Neuron And An Associated Prothoracic Network Are Involved In Calling Song Recognition By Female Crickets, John Stout, Nathan Carlson, Hilary Bingol, James Ramseier, Michael Bronsert, Gordon Atkins

Faculty Publications

In young virgin Acheta domesticus females, the spiking response of the prothoracic L3 auditory interneuron discriminates between calling songs (CSs) with phonotactically attractive and unattractive syllable periods (SPs), which parallels phonotactic discrimination. Presentation of a CS with an originally attractive SP, but with the intensity modulated so as to minimize L3's selective response, results in a CS with little phonotactic attractiveness. Conversely, a CS with an originally unattractive SP becomes much more attractive when the CS is intensity modulated in ways that duplicate L3's selective response. L3's discriminatory response to CS SP deteriorates with age, in parallel with decreased phonotactic …

Major Features And Forcing Of High‐Latitude Northern Hemisphere Atmospheric Circulation Using A 110,000‐Year‐Long Glaciochemical Series, Paul A. Mayewski, L. David Meeker, Mark S. Twickler, Sallie I. Whitlow, Qinzhao Yang, W. Berry Lyons, Michael Prentice

Charged particle production has been measured in deep inelastic scattering (DIS) events over a large range of x and Q2 using the ZEUS detector. The evolution of the scaled momentum, xp, with Q2, in the range 10 to 1280 GeV2, has been investigated in the current fragmentation region of the Breit frame. The results show clear evidence, in a single experiment, for scaling violations in scaled momenta as a function of Q2. © 1997 Elsevier Science B.V.

Chern-Simons States In Spin-Network Quantum Gravity, Rodolfo Gambini, Jorge Griego, Jorge Pullin

Faculty Publications

In the context of canonical quantum gravity in terms of Ashtekar's new variables, it is known that there exists a state that is annihilated by all the quantum constraints and that is given by the exponential of the Chern-Simons form constructed with the Asthekar connection. We make a first exploration of the transform of this state into the spin-network representation of quantum gravity. The discussion is limited to trivalent nets with planar intersections. We adapt an invariant of tangles to construct the transform and study the action of the Hamiltonian constraint on it. We show that the first two coefficients …

Faculty Publications

Events containing an isolated prompt photon with high transverse energy, together with a balancing jet, have been observed for the first time in photoproduction at HERA. The data were taken with the ZEUS detector, in a γp centre of mass energy range 120-250 GeV. The fraction of the incoming photon energy participating in the production of the prompt photon and the jet, xγ, shows a strong peak near unity, consistent with LO QCD Monte Carlo predictions. In the transverse energy and pseudorapidity range 5 ≤ EγT < 10 GeV, -0.7 ≤ ηγ < 0.8, EjetT ≥ 5 GeV, and -1.5 ≤ ηjet ≤ 1.8, with xOBSγ > 0.8, the measured cross section is 15.3 ± 3.8 ± 1.8 pb, in good …

Large Quantum Gravity Effects: Backreaction On Matter, Rodolfo Gambini, Jorge Pullin

Faculty Publications

We re-examine the large quantum gravity effects discovered by Ashtekar in the context of (2 + 1)-dimensional gravity coupled to matter. We study an alternative one-parameter family of coherent states of the theory in which the large quantum gravity effects on the metric can be diminished, at the expense of losing coherence in the matter sector. Which set of states is the one that occurs in nature will determine if the large quantum gravity effects are actually observable as wild fluctuations of the metric or rapid loss of coherence of matter fields. © World Scientific Publishing Company.

Where Are We Now?: Life After Electromation, Rafael Gely

Faculty Publications

Given the expectations that preceded the Board's decisions, and the reactions that followed, it is somewhat surprising how little attention has been given to the decisions the NLRB has issued since Electromation and E.I. du Pont. While in general these recent decisions are consistent with the holdings in Electromation and E.I. du Pont, they provide us with the opportunity to analyze the manner in which the Board is currently dealing with the legality of workplace cooperative efforts. This article explores that issue. Part II of the article provides a brief overview of the workplace cooperative efforts problem. Part III reviews …

Faculty Publications

The chemical engineering curriculum in the United States has trained generations of technical experts who have successfully optimized chemical processes and products once they entered the chemical industry. The U.S. chemical industry, however, has entered a critical stage in which it must be able to create new and differentiated value through technical innovations that arc essential for long-term survival. This innovation process will require new skills that go far beyond the traditional expertise for the optimization of tasks possessed by young chemical engineers. The innovators must be able to identify new opportunities, explore the boundaries of technology, evaluate critical issues, …

This paper presents measurements of D*f± production in deep inelastic scattering from collisions between 27.5GeV positrons and 820GeV protons. The data have been taken with the ZEUS detector at HERA. The decay channel D*+ → (D0 → K-π+)π+ (+c.c.) has been used in the study. The e+p cross section for inclusive D*± production with 5 < Q2 < 100GeV2 and y < 0.7 is 5.3±1.0±0.8nb in the kinematic region 1.3 < pT(D*±) < 9.0GeV and |η(D*±) | < 1.5. Differential cross sections as functions of pT(D*±), η(D*±), W and Q2 are compared with next-to-leading order QCD calculations based on the photon-gluon fusion production mechanism. After an extrapolation of the cross section to the full kinematic region in pT(D*±) and η(D*±), the charm contribution Fcc̄2(x,Q2) to the proton structure function is determined for Bjorken x between 2 · 10-4 and 5 · 10-3. © 1997 Elsevier Science B.V.

Autopsy In The Cancer Patient: The Nurse's Role, Patricia Rushton

Faculty Publications

Nurses spend many hours with dying cancer patients, developing close relationships with both the patients and their families. However, nurses are frequently not involved in the process of requesting an autopsy, either by choice or tradition. During this time of great stress, the nurse can be more involved. The nurse who understands the reasons for autopsy and its ramification for the grieving process can be actively involved in supporting the physician who makes the request and the family members who must make the this difficult decision. It is possible that the nurse can be the health team member designated to …

Azimuthal Modulation Of C-Band Scatterometer Over Southern Ocean Sea Ice, David G. Long, David S. Early

Faculty Publications

In a continuing evaluation of the ERS-1 C-band scatterometer as a tool for studying polar sea ice, the authors evaluate the azimuthal modulation characteristics of Antarctic sea ice. ERS-1 AMI scatterometer mode data sets from several study regions dispersed in the Antarctic seasonal sea ice pack are evaluated for azimuthal modulation. When appropriate, the incidence angle dependence is estimated and removed in a study region before determining whether azimuthal modulation is present in the data. Other comparisons are made using the fore and aft beam measurement difference. The results show that over the ice pack, azimuthal modulation is less than …

These dimers form infinite stacks in the crystal stabilized by π-π interactions between the aromatic ring systems.

In Vivo Kinetics Of A Redox-Regulated Transcriptional Switch, Huangen Ding, Bruce Demple

Faculty Publications

SoxR is a transcription activator governing a cellular response to superoxide and nitric oxide in Escherichia coli. SoxR protein is a homodimer, and each monomer has a redox-active [2Fe-2S] cluster. Oxidation and reduction of the [2Fe-2S] clusters can reversibly activate and inactivate SoxR transcriptional activity. Here, we use electron paramagnetic resonance spectroscopy to follow the redox-switching process of SoxR protein in vivo. SoxR [2Fe-2S] clusters were in the fully reduced state during normal aerobic growth, but were completely oxidized after only 2-min aerobic exposure of the cells to superoxide-generating agents such as paraquat. The oxidized SoxR [2Fe-2S] clusters were rapidly …

A Unified Green's Function Analysis Of Complicated Dfb Lasers, Jim D. Freeze, Michael A. Jensen, Richard H. Selfridge

Faculty Publications

An efficient full-wave analysis technique for one-dimensional optical domains, known as the recursive Green's function method (RGFM), is presented for evaluation of distributed feedback (DFB) laser cavities with arbitrary material profiles. The method first constructs the Green's function of an inhomogeneous domain and subsequently uses Green's theorem to determine the laser optical field, lasing wavelength, and threshold gain. The technique is applied to investigate the performance of three DFB laser structures: a chirped-grating configuration, a modulated stripe width design, and a reduced duty cycle complex-coupled device. These structures are evaluated in terms of their single-mode lasing behavior and the uniformity …

Time Series Measurements Of Chlorophyll Fluorescence In The Oceanic Bottom Boundary Layer With A Multisensor Fiber-Optic Fluorometer, Eurico J. Dsa, Steven E. Lohrenz, Vernon L. Asper, Roy A. Walters

Faculty Publications

An in situ multisensor fiber-optic fluorometer (MFF) has been developed to acquire long-term chlorophyll fluorescence measurements in the oceanic bottom boundary layer to characterize the finescale pigment structure at vertical spatial scales comparable to physical measurements. The eight fluorescence sensors of the MFF are composed of dual optical fibers of varying lengths (1.5-8 m), with the fiber ends oriented at 30 degrees to each other and enclosed by a small light baffle. Strobe excitation blue light is passed through one of each pair of optical fibers and stimulated chlorophyll fluorescence is carried back to a photomultiplier. Two sets of four …

Evolution And Nebulousness In Theories, Barry N. Markovsky

Faculty Publications

Social scientists have a clear choice in how they may approach theory development. One path leads to "nebulous" theories that lack any real explanatory power. The other path capitalizes on evolutionary principles of variation and selection, vastly increasing the chances for explanatory success. I illustrate these ideas by reference to "artificial life" programs, and discuss the implications for theory construction in the social sciences.

How Will Lawyering And Mediation Practices Transform Each Other?, John M. Lande

Faculty Publications

This article sketches out some aspects of both lawyering and mediation practice that may be affected by development of a litimediation culture. Part II examines the growth of the private market for mediation and an accompanying specialization of mediation practice. These changes seem likely to require mediators to develop market niches with identifiable characteristics of their mediation practices. Simultaneously, lawyers, as regular buyers of mediation services, will be expected to recognize and make decisions based on significant distinctions between mediation providers.
