Responding to Interactive Troubles – Implications for School Culture
Responding to interactive troubles in schools can create processes of exclusion and marginalization. Certain basic assumptions can become knitted into school culture in ways that give rise to specific exclusionary practices. However, it does not have to be this way. Inclusionary ways of responding to interactive troubles can also be produced, given a school culture that nurtures relational ways of engagement. This article presents such relational practices and argues thoroughly for their use
A number or a person?: perspectives on credit scoring and fair mortgage lending: article four in a five-part series
This fourth article in a five-part series on credit scoring showcases three different perspectives. Up for debate is how lenders can ensure fair treatment to all mortgage applicants and how consumers can be educated about the effect their credit score has on loan pricing.Mortgage loans
MOE11 Emittance Growth from the Thermalization of Space-Charge Nonuniformities
Beams injected into a linear focusing channel typically have some degree of
space-charge nonuniformity. In general, injected particle distributions with
systematic charge nonuniformities are not equilibria of the focusing channel
and launch a broad spectrum of collective modes. These modes can phase-mix and
have nonlinear wave-wave interactions which, at high space-charge intensities,
results in a relaxation to a more thermal-like distribution characterized by a
uniform density profile. This thermalization can transfer self-field energy
from the initial space-charge nonuniformity to the local particle temperature,
thereby increasing beam phase space area (emittance growth). In this paper, we
employ a simple kinetic model of a continuous focusing channel and build on
previous work that applied system energy and charge conservation quantify
emittance growth associated with the collective thermalization of an initial
azimuthally symmetric, rms matched beam with a radial density profile that is
hollowed or peaked. This emittance growth is shown to be surprisingly modest
even for high beam intensities with significant radial structure in the initial
density profile.Comment: Paper MOE11, XX International Linac Conference, Monterey, CA 21-25

CLIMODE bobber data report : July 2005 - May 2009
This report summarizes direct observations of Eighteen Degree Water (EDW) subduction
and dispersal within the subtropical gyre of the North Atlantic Ocean. Forty acoustically-tracked
bobbing, profiling floats (“bobbers”) were deployed to study the formation and
dispersal of EDW in the western North Atlantic. The unique bobber dataset described
herein provides insight into the evolution of EDW by means of direct, eddy-resolving
measurement of EDW Lagrangian dispersal pathways and stratification. Bobbers are
modified Autonomous Profiling Explorer (APEX) profiling floats which actively servo
their buoyancy control mechanism to follow a particular isothermal surface. The
CLIVAR Mode Water Dynamics Experiment (CLIMODE) bobbers tracked the 18.5°C
temperature surface for 3 days, then bobbed quickly between the 17°C and 19°C
isotherms. This cycle was repeated for one month, after which each bobber profiled to
1000 m before ascending to the surface to transmit data. The resulting dataset (37/40
tracked bobbers; more than half still profiling as of January 2010) yields well-resolved
trajectories, unprecedented velocity statistics in the core of the subducting and spreading
EDW, and detailed information about the Lagrangian evolution of EDW thickness and
vertical structure. This report provides an overview of the experimental procedure
employed and summarizes the initial processing of the bobber dataset.Funding was provided by the National Science Foundation under Grant No. OCE-0424492
CLIVAR Mode Water Dynamics Experiment (CLIMODE) fall 2005, R/V Oceanus voyage 419, November 9, 2005–November 27, 2005
CLIMODE (CLIVAR Mode Water Dynamic Experiment) is a program designed to understand and quantify the processes
responsible for the formation and dissipation of North Atlantic subtropical mode water, also called Eighteen Degree Water (EDW).
Among these processes, the amount of buoyancy loss at the ocean-atmosphere interface is still uncertain and needs to be accurately
quantified. In November 2005, a cruise was made aboard R/V Oceanus in the region of the separated Gulf Stream, where intense
oceanic heat loss to the atmosphere is believed to trigger the formation of EDW. During that cruise, one surface mooring with
IMET meteorological instruments was anchored in the core of the Gulf Stream as well as two moored profilers on its southeastern
edge. Surface drifters, APEX floats and bobby RAFOS floats were also deployed along with two other moorings with sound
sources. CTD profiles and water samples were also carried out. This array of instruments will permit a characterization of EDW
with high spatial and temporal resolutions, and accurate in-situ measurements of air-sea fluxes in the formation region. The
present report documents this cruise, the instruments that were deployed and the array of measurements that was set in place.Funding was provided by the National Science Foundation under Grant No. OCE 04-24536
A Comparison of Potential Mixes in Two Southeastern Lakes: Lake Jocassee, SC and Carters Lake, GA
In the Southeast United States most lakes tend to be warm monomictic lakes, mixing during one season each year. However, under circumstances of great relative depth, lakes may tend towards meromictic conditions. In this case the bottom layer of the lake, or the monimolimnion, never mixes completely. Carter’s Lake in Chatsworth, Georgia was created in 1977 after the creation of Carter’s Dam, and is an example of a meromictic lake. Lake Jocassee is a reservoir located in Salem, South Carolina on the Savannah River Basin. The reservoir was created in 1973 upon the completion of The Jocassee Pumped Storage Hydroelectric Station. Like Carter’s Lake, Lake Jocassee is very deep and large, and has the possibility of behaving as a meromictic lake. Past data suggests that Lake Jocassee behaves more frequently as a warm monomictic lake while occasionally not mixing completely. We wanted to further study Lake Jocassee’s morphometry to dig deeper into the possibility of meromixis within the lake by looking at the level of mixing in the Winter of 2014

At Sea Test 2 recovery cruise : Cruise 206 on board R/V Knorr April 10 - 15, 2012 Woods Hole - Woods Hole, MA
The R/V Knorr, on Cruise 206, carried out the recovery of three moorings for the Coastal
and Global Scale Nodes (CGSN) Implementing Organization of the NSF Ocean
Observatories Initiative. These three moorings are prototypes of the moorings to be used
by CGSN at the Pioneer, Endurance, and Global Arrays. Knorr departed from Woods
Hole, Massachusetts on April 10, 2012 and steamed south to the location of the mooring
deployments on the shelf break. Over five days, April 10-15, Knorr surveyed the bottom
at the planned mooring sites, recovered the moorings, and carried out preliminary
investigations of mechanical and electrical functionality on the recovered moorings and
mooring hardware, including observations of biofouling and corrosion. Knorr returned to
Woods Hole on April 15, 2012.Funding was provided by the National Science Foundation contract #SA9-10 through the

CLIVAR Mode Water Dynamics Experiment (CLIMODE) fall 2006 R/V Oceanus voyage 434 November 16, 2006–December 3, 2006
CLIMODE (CLIVAR Mode Water Dynamic Experiment) is a research program designed to
understand and quantify the processes responsible for the formation and dissipation of North
Atlantic subtropical mode water, also called Eighteen Degree Water (EDW). Among these
processes, the amount of buoyancy loss at the ocean-atmosphere interface is still uncertain and
needs to be accurately quantified.
In November 2006, cruise 434 onboard R/V Oceanus traveled in the region of the separated Gulf
Stream and its recirculation, where intense oceanic heat loss to the atmosphere in the winter is
believed to trigger the formation of EDW. During this cruise, the surface mooring F that was
anchored in the core of the Gulf Stream was replaced by a new one, as well as two subsurface
moorings C and D located on the southeastern edge of the stream. Surface drifters, ARGO and
bobbers RAFOS floats were deployed, CTD profiles and water samples were also carried out.
This array of instruments will permit a characterization of EDW with high spatial and temporal
resolutions and accurate in-situ measurements of air-sea fluxes in the EDW formation region.
The present report documents this cruise, the methods and locations for the deployments of
instruments and some evaluation of the measurements from these instruments.Funding was provided by the National Science Foundation under contract No. OCE04-2453
