Moving occupation into treatment: clinical interpretation of legitimizing occupational therapy\u27s knowledge .
Clinical interpretation of health and the human spirit for occupation .
In reading and contemplating Yenca\u27s (1998) article, I was immediately struck by the utility of the ideas she offers on a number of clinical fronts. We are presented with occupation-based strategies that are directly applicable to our work with patients and program development; we can make use of the language and ideas that are offered as a way to begin talking to one another (therapist to therapist) in clinical settings about occupation; and we are given the opportunity to think about the contribution, value, and efficacy of occupation and how we might convert those ideas into clinically based research actions. This last point is especially useful given Yerxa\u27s powerful view of the complex and compelling human and person issues that are looming on the horizon (achieving healthfulness, finding valued substitutes for work). In response to these person dilemmas of the future, it is exciting to consider what kinds of new treatment approaches, programming ideas, and research questions might be most appropriate for us to develop on me basis of our understanding of the importance of occupation to health

An RF Circuit Model for Carbon Nanotubes
We develop an rf circuit model for single walled carbon nanotubes for both dc
and capacitively contacted geometries. By modeling the nanotube as a
nano-transmission line with distributed kinetic and magnetic inductance as well
as distributed quantum and electrostatic capacitance, we calculate the complex,
frequency dependent impedance for a variety of measurement geometries. Exciting
voltage waves on the nano-transmission line is equivalent to directly exciting
the yet-to-be observed one dimensional plasmons, the low energy excitation of a
Luttinger liquid.Comment: 4 pages, 4 figures. To be published in the proceedings of IEEE-NANO

Representation in Westminster in the 1990s : The ghost of Edmund Burke
Why are 'trustee' notions of representation still invoked in the UK House of Commons in the 1990s? In answering this question this article analyses the premises of Burkean theory and the arguments that these premises are of little relevance in the late twentieth century. Despite these dismissals of trusteeship, Burkean ideas are still articulated in the Commons some 200 years after they were first voiced. The idea of trusteeship can prove extremely useful to justify the actions of representatives when those actions conflict with constituency 'opinion', party policy or the wishes of interest groups. Examples of the occasions when Burkean notions have been invoked in the 1990s are provided
A combined R-matrix eigenstate basis set and finite-differences propagation method for the time-dependent Schr\"{od}dinger equation: the one-electron case
In this work we present the theoretical framework for the solution of the
time-dependent Schr\"{o}dinger equation (TDSE) of atomic and molecular systems
under strong electromagnetic fields with the configuration space of the
electron's coordinates separated over two regions, that is regions and
. In region the solution of the TDSE is obtained by an R-matrix basis
set representation of the time-dependent wavefunction. In region a grid
representation of the wavefunction is considered and propagation in space and
time is obtained through the finite-differences method. It appears this is the
first time a combination of basis set and grid methods has been put forward for
tackling multi-region time-dependent problems. In both regions, a high-order
explicit scheme is employed for the time propagation. While, in a purely
hydrogenic system no approximation is involved due to this separation, in
multi-electron systems the validity and the usefulness of the present method
relies on the basic assumption of R-matrix theory, namely that beyond a certain
distance (encompassing region ) a single ejected electron is distinguishable
from the other electrons of the multi-electron system and evolves there (region
II) effectively as a one-electron system. The method is developed in detail for
single active electron systems and applied to the exemplar case of the hydrogen
atom in an intense laser field.Comment: 13 pages, 6 figures, submitte
Differential Mortality and Retirement Benefits in the Health and Retirement Study
This analysis uses data from the Health and Retirement Study (HRS) to examine the sources of variation in mortality for individuals of varying socio-economic status (SES). The use of the HRS allows a distinction between education and a measure of career earnings as primary determinants of socio-economic status for men and women separately. We use those predictions of mortality to estimate the distribution of annual and lifetime OASDI benefits for different birth cohorts spanning the birth years from 1900 to 1950. We find differential rates of mortality have had substantial effects in altering the distribution lifetime benefits in favor of higher income individuals
Localised states in an extended Swift-Hohenberg equation
Recent work on the behaviour of localised states in pattern forming partial
differential equations has focused on the traditional model Swift-Hohenberg
equation which, as a result of its simplicity, has additional structure --- it
is variational in time and conservative in space. In this paper we investigate
an extended Swift-Hohenberg equation in which non-variational and
non-conservative effects play a key role. Our work concentrates on aspects of
this much more complicated problem. Firstly we carry out the normal form
analysis of the initial pattern forming instability that leads to
small-amplitude localised states. Next we examine the bifurcation structure of
the large-amplitude localised states. Finally we investigate the temporal
stability of one-peak localised states. Throughout, we compare the localised
states in the extended Swift-Hohenberg equation with the analogous solutions to
the usual Swift-Hohenberg equation
