A hidden dimension? Work ideology and psychological contracts.
This paper explores whether the concept of psychological contracts underpinned by relational/transactional exchanges provides an adequate description of knowledge workers’ contracts. Interviews were conducted with scientists from the CSIRO. The analysis identified content of the psychological contract for the knowledge worker best understood by reference to an ideological currency. It raises questions over the role of normative occupation-specific beliefs about work, and the sharing of common currency elements by individuals in the same organization within the same occupation. The analysis lends support to calls in the literature for a reconsideration of the transactional/relational interpretative framework that underpins the psychological contract
The psychological contract of knowledge workers
Purpose: This paper explores whether the concept of psychological contracts underpinned by relational/transactional exchanges provides an adequate description of knowledge workers’ contracts.
Methodology: The research approach uses interviews with 10 scientists from within a pre-eminent Australian scientific research and development organisation, the Commonwealth Scientific & Industrial Research Organisation (CSIRO).
Findings: The research strong evidence of an ideological currency within the psychological contract for this set of knowledge workers.
Implications: The research raises questions over the role of normative occupation-specific beliefs about work, and the sharing of common currency elements by individuals in the same organization within the same occupation. The analysis lends support to calls in the literature for a reconsideration of the transactional/relational interpretative framework that underpins the psychological contract
Hyperfine, rotational and Zeeman structure of the lowest vibrational levels of the Rb \tripletex state
We present the results of an experimental and theoretical study of the
electronically excited \tripletex state of Rb molecules. The
vibrational energies are measured for deeply bound states from the bottom up to
using laser spectroscopy of ultracold Rb Feshbach molecules. The
spectrum of each vibrational state is dominated by a 47\,GHz splitting into a
\cog and \clg component caused mainly by a strong second order spin-orbit
interaction. Our spectroscopy fully resolves the rotational, hyperfine, and
Zeeman structure of the spectrum. We are able to describe to first order this
structure using a simplified effective Hamiltonian.Comment: 10 pages, 7 figures, 2 table
Fractal Conductance Fluctuations in Gold--Nanowires
A detailed analysis of magneto-conductance fluctuations of quasiballistic
gold-nanowires of various lengths is presented. We find that the variance
when analyzed for much
smaller than the correlation field varies according to with indicating that the graph of
vs. is fractal. We attribute this behavior to the existence of
long-lived states arising from chaotic trajectories trapped close to regular
classical orbits. We find that decreases with increasing length of the
wires.Comment: 5 pages, Revtex with epsf, 4 Postscript figures, final version

Spectral Properties of delta-Plutonium: Sensitivity to 5f Occupancy
By combining the local density approximation (LDA) with dynamical mean field
theory (DMFT), we report a systematic analysis of the spectral properties of
-plutonium with varying occupancy. The LDA Hamiltonian is
extracted from a tight-binding (TB) fit to full-potential linearized augmented
plane-wave (FP-LAPW) calculations. The DMFT equations are solved by the exact
quantum Monte Carlo (QMC) method and the Hubbard-I approximation. We have shown
for the first time the strong sensitivity of the spectral properties to the
occupancy, which suggests using this occupancy as a fitting parameter in
addition to the Hubbard . By comparing with PES data, we conclude that the
``open shell'' configuration gives the best agreement, resolving the
controversy over ``open shell'' versus ``close shell'' atomic
configurations in -Pu.Comment: 6 pages, 2 embedded color figures, to appear in Physical Review
Superconducting Proximity Effect and Universal Conductance Fluctuations
We examine universal conductance fluctuations (UCFs) in mesoscopic
normal-superconducting-normal (N-S-N) structures using a numerical solution of
the Bogoliubov - de Gennes equation. We discuss two cases depending on the
presence (``open'' structure) or absence (``closed'' structure) of
quasiparticle transmission. In contrast to N-S structures, where the onset of
superconductivity increases fluctuations, we find that UCFs are suppressed by
superconductivity for N-S-N structures. We demonstrate that the fluctuations in
``open'' and ``closed'' structures exhibit distinct responses to an applied
magnetic field and to an imposed phase variation of the superconducting order
parameter.Comment: (4 pages, 5 figures). Corrected typos in equations, added references,

Radiological risk assessment for the remote-handled transuranic waste storage options at Argonne National Laboratory - East.
Interim storage of the remote-handled transuranic (RH/TRU) waste is needed at Argonne National Laboratory-East (ANL-E). Two on-site facilities, the northwest (NW) vaults in the 317 Area and the converted spent nuclear fuel pool in Building 331, were identified as potential storage locations through previous studies. To assist the decision making process of selecting a storage location, radiological risk assessments were conducted to analyze potential radiation exposures that would be associated with storage of the RH/TRU waste in these two facilities. Three drum storage scenarios (one for the 317 Area and two for Building 331) considering different drum handling procedures and stacking patterns were developed. Time-motion information on worker activities that would occur in the procedures was collected and recorded in spreadsheets. Using the time-motion information, potential external doses were estimated for the involved workers for each step in the procedures. The sum of the potential external doses over all the activity steps gave the total collective dose for each scenario. The results show that during the storage phase, storing waste drums in half-liners in Building 331 would result in the lowest collective radiation exposure; however, it would also require the most human resources. When retrieving waste drums for off-site shipment was considered, storing waste drums in the 317 Area would be the most favorable option because it would require the least amount of human resources and would also result in the lowest collective radiation exposure
Photoassociation of sodium in a Bose-Einstein condensate
We report on the formation of ultra-cold Na molecules using single-photon
photoassociation of a Bose-Einstein condensate. The photoassociation rate,
linewidth and light shift of the J=1, vibrational level of the
\mterm{A}{1}{+}{u} molecular bound state have been measured. We find that the
photoassociation rate constant increases linearly with intensity, even where it
is predicted that many-body effects might limit the rate. Our observations are
everywhere in good agreement with a two-body theory having no free parameters.Comment: Fixes to the figures and references. Just the normal human stupidity
