Weight management and its role in breast cancer rehabilitation
Overweight and obesity are risk factors for post-menopausal breast cancer, and many women diagnosed with breast cancer, irrespective of menopausal status, gain weight after diagnosis. Weight management plays an important role in rehabilitation and recovery since obesity and/or weight gain may lead to poorer breast cancer prognosis, as well as prevalent co-morbid conditions (e.g. cardiovascular disease and diabetes), poorer surgical outcomes (e.g., increased operating and recovery times, higher infection rates, and poorer healing), lymphedema, fatigue, functional decline, and poorer health and overall quality of life. Health care professionals should encourage weight management at all phases of the cancer care continuum as a means to potentially avoid adverse sequelae and late effects, as well as to improve overall health and possibly survival. Comprehensive approaches that involve dietary and behavior modification, and increased aerobic and strength training exercise have shown promise in either preventing weight gain or promoting weight loss, reducing biomarkers associated with inflammation and co-morbidity, and improving lifestyle behaviors, functional status, and quality of life in this high-risk patient population
A Model of Three-Dimensional Lattice Gravity
A model is proposed which generates all oriented simplicial complexes
weighted with an invariant associated with a topological lattice gauge theory.
When the gauge group is , it is the Turaev-Viro invariant and
the model may be regarded as a non-perturbative definition of simplicial
quantum gravity. If one takes a finite abelian group , the corresponding
invariant gives the rank of the first cohomology group of a complex
\nolinebreak : , which means a topological
expansion in the Betti number . In general, it is a theory of the
Dijkgraaf-Witten type, determined completely by the fundamental group of
a manifold.Comment: 20 page
The Outsiders: An essay on Transport Planning Methods
This paper examines the concept of transport disadvantage and how people who are defined as such are ill served by commonly used transport planning processes. The notion of mobility and the difference between need and demand are examined as are the issues of access and equity especially in reference to transport subsidies. Non-mainstream transport solutions such as paratransit or community transport are explored. Transport planning is examined with criticism of some forms of transport modelling with reference to transport disadvantage. Finally a case is made for public participation in transport planning processes and for transport planning at a local level
Novel QCD Phenomenology
I review a number of topics where conventional wisdom in hadron physics has
been challenged. For example, hadrons can be produced at large transverse
momentum directly within a hard higher-twist QCD subprocess, rather than from
jet fragmentation. Such "direct" processes can explain the deviations from
perturbative QCD predictions in measurements of inclusive hadron cross sections
at fixed x_T= 2p_T/\sqrt s, as well as the "baryon anomaly", the anomalously
large proton-to-pion ratio seen in high centrality heavy ion collisions.
Initial-state and final-state interactions of the struck quark lead to
Bjorken-scaling single-spin asymmetries, diffractive deep inelastic scattering,
the breakdown of the Lam-Tung relation in Drell-Yan reactions, as well as
nuclear shadowing and antishadowing. The Gribov-Glauber theory predicts that
antishadowing of nuclear structure functions is not universal, but instead
depends on the flavor quantum numbers of each quark and antiquark, thus
explaining the anomalous nuclear dependence measured in deep-inelastic neutrino
scattering. One cannot attribute such phenomena to the structure of the hadron
or nucleus itself. It is thus important to distinguish "static" structure
functions computed from the square of the target light-front wavefunctions,
versus "dynamical" structure functions which include the effects of the
final-state rescattering of the struck quark. The importance of the J=0
photon-quark QCD contact interaction in deeply virtual Compton scattering is
emphasized. The scheme-independent BLM method for setting the renormalization
scale is discussed. Eliminating the renormalization scale ambiguity greatly
improves the precision of QCD predictions and increases the sensitivity of
searches for new physics at the LHC. Other novel features of QCD are discussed,
including the consequences of confinement for quark and gluon condensates.Comment: Invited talk, presented at the Gribov-80 Memorial Workshop on Quantum

Worshipping Bacchus: Prohibition in Savannah, 1899-1922
‘Worshipping Bacchus: Prohibition in Savannah, 1899-1922’ examines the failure of prohibition at the local level. Savannah’s citizens determined to quench their thirst in defiance of state and subsequently national law. In the process, they received unofficial sanction of the local government, whose leaders refused to criminalize the manufacture and sale of alcohol. Prohibitionists could not use their significant organizational ability and lobbying to compel enforcement. Their efforts demonstrated not only the weakness of the state executive but more importantly the real power held by local governments
