Integrated Behavioral Health Training in Counselor Education: A Call to Action
The American healthcare system is beginning to adopt an integrated behavioral health model as a way to meet the ever-changing and holistic needs of patients by creating opportunities for collaboration among medical and behavioral health professionals. Professional counselors play a vital role in integrative behavioral health through their meaningful participation on interdisciplinary healthcare teams. Professional counselors are key to any interdisciplinary team because they embrace a biopsychosocial wellness perspective and have undergone clinical and academic training. However, many counseling programs do not specifically educate or train counselors in how to work in integrated care settings. As such, counselor educators must adapt to this evolving system of healthcare by providing students with didactic and experiential learning opportunities to promote competence and readiness to practice in this new wave of healthcare
Planar Symmetry Detection and Quantification using the Extended Persistent Homology Transform
Symmetry is ubiquitous throughout nature and can often give great insights
into the formation, structure and stability of objects studied by
mathematicians, physicists, chemists and biologists. However, perfect symmetry
occurs rarely so quantitative techniques must be developed to identify
approximate symmetries. To facilitate the analysis of an independent variable
on the symmetry of some object, we would like this quantity to be a smoothly
varying real parameter rather than a boolean one. The extended persistent
homology transform is a recently developed tool which can be used to define a
distance between certain kinds of objects. Here, we describe how the extended
persistent homology transform can be used to visualise, detect and quantify
certain kinds of symmetry and discuss the effectiveness and limitations of this
method.Comment: 9 pages, 13 figure
Investigation and comparison of multi-state and two-state atom laser output-couplers
We investigate the spatial structure and temporal dynamics created in a
Bose-Einstein condensate (BEC) by radio-frequency (RF) atom laser
output-couplers using a one-dimensional mean-field model. We compare the
behavior of a `pure' two-state atom laser to the multi-level systems
demonstrated in laboratories. In particular, we investigate the peak
homogeneous output flux, classical fluctuations in the beam and the onset of a
bound state which shuts down the atom laser output.Comment: 9 pages, 8 figure
The Role of Source Coherence in Atom Interferometery
The role of source cloud spatial coherence in a Mach-Zehnder type atom
interferometer is experimentally investigated. The visibility and contrast of a
Bose-Einstein condensate (BEC) and three thermal sources with varying spatial
coherence are compared as a function of interferometer time. At short times,
the fringe visibility of a BEC source approaches 100 % nearly independent of pi
pulse efficiency, while thermal sources have fringe visibilities limited to the
mirror efficiency. More importantly for precision measurement systems, the BEC
source maintains interference at interferometer times significantly beyond the
thermal source
80hk Momentum Separation with Bloch Oscillations in an Optically Guided Atom Interferometer
We demonstrate phase sensitivity in a horizontally guided,
acceleration-sensitive atom interferometer with a momentum separation of 80hk
between its arms. A fringe visibility of 7% is observed. Our coherent pulse
sequence accelerates the cold cloud in an optical waveguide, an inherently
scalable route to large momentum separation and high sensitivity. We maintain
coherence at high momentum separation due to both the transverse confinement
provided by the guide, and our use of optical delta-kick cooling on our
cold-atom cloud. We also construct a horizontal interferometric gradiometer to
measure the longitudinal curvature of our optical waveguide.Comment: 6 pages, 6 figure
An LSE action plan for a strong and sustainable recovery
What does ‘building back better’ actually mean? Nicholas Stern, Sam Unsworth, Anna Valero, Dimitri Zenghelis, James Rydge and Nick Robins (LSE) set out the actions the government needs to take to deliver a sustainable recovery
