Due Process Hearing Officers: Characteristics, Needs, and Appointment Criteria
This is the publisher's version, also found here: http://sped.org/Characteristics and training
needs of due process hearing officers in
North Carolina were surveyed. It was
found that current regulations governing
appointments of hearing officers are
insufficient to ensure appointment of
qualified and impartial persons. Criteria
were analyzed and suggestions for
training and appointments are made
Signature of nearly icosahedral structures in liquid and supercooled liquid Copper
A growing body of experiments display indirect evidence of icosahedral
structures in supercooled liquid metals. Computer simulations provide more
direct evidence but generally rely on approximate interatomic potentials of
unproven accuracy. We use first-principles molecular dynamics simulations to
generate realistic atomic configurations, providing structural detail not
directly available from experiment, based on interatomic forces that are more
reliable than conventional simulations. We analyze liquid copper, for which
recent experimental results are available for comparison, to quantify the
degree of local icosahedral and polytetrahedral order
Fabrication of free-standing ordered fluorescent polymer nanofibres by electrospinning
The authors are grateful to the Engineering and Physical Sciences Research Council for financial support.We demonstrate a static fabrication approach to make free-standing ordered arrays of fluorescent nanofibres through control of the transverse electrospinning field. The alignment and the density of the nanofibre arrays are optimised by careful design of both the source and collector electrode geometries which can control the transverse electric field over the full path of the jet. In doing so, we fabricate suspended fluorescent nanofibres with an aspect ratio of 10(4), and with a substantially increased density and order parameter (by a factor of similar to 10 compared to random deposition). Electrostatic modelling suggests that the field distribution of the component is the main contribution to the ordering between the plates. This method offers increased efficiency for the creation of ordered fibres collected over a small area and the characterisation of their photoluminescent properties.Publisher PDFPeer reviewe
Procedural Due Process: The Two-edged Sword That the Untrained Should Not Unsheath
The issue of procedural due process is examined in this article by first analyzing
the associated legal requirements of P.L. 94-142 and then identifying the "triggers"
which professionals and parents can use to initiate a due process hearing.
Problems and unresolved issues associated with interpreting and applying due process
safeguards in terms of initiating, conducting, and governing the hearing and
hearing officer are discussed. The concluding section of the article identifies
specific training implications and creeds of due process hearing officers
