Significant learning principles as reedmaking pedagogy
Reedmaking is as integral to oboists’ skills as performers and teachers as any other element of their musical study. Reeds regulate almost all aspects of oboists’ music making, including pitch, line, and tone. But reedmaking is also the part of oboists’ professional training least integrated with their overall music education. Currently available resources on oboe reedmaking are written for the practitioner, and tend to be technical rather than pedagogical in nature. They do not cater to oboists’ varying backgrounds in reedmaking; nor do they take into account a given student’s unique physiology, technique, or variations in the instruments themselves. Indeed, techniques for teaching reedmaking have barely changed since the oral tradition of the nineteenth
century. Given these shortcomings, there is great opportunity for instructional reexamination and intervention in the teaching of reedmaking.
This dissertation blends reedmaking’s pedagogical traditions with principles from L. Dee Fink’s theory of “significant learning” into a useful, task-based guide for oboe professors in modern collegiate settings. First, it surveys historical writings on reedmaking and reedmaking pedagogy from the invention of the oboe to present day. It then examines relevant data and narratives about typical modern reedmaking pedagogy in the context of higher education. Third, it envisions reedmaking curricula based on significant learning principles. Finally, it explores broader implications for the oboe studio, other performance studios, and the expansion of a literature of reedmaking pedagogy
Growing Together Separately: An Analysis of the Influence of Individualism in an Alternative Educational Setting
Alternative educational settings that attempt to challenge Individualism are pervaded by Individualizing influences from the larger school system. This thesis examines the influences of Individualism in a school garden program at a Southern California continuation high school. Program members included high school students, college student interns, and two co-directors. Research was conducted during the spring semester of 2014. By providing an analysis of the Individualizing and non-Individualizing influences present in the program and the ways in which these influences interacted to inform the program structure and program members’ experiences and understandings, my thesis sheds new light on the complex ways alternative educational settings incorporate some aspects of Individualism, even as they challenge it
Fire to Vellum
Oswic’s simple life changed the day his mother died from poison. After finding a strange cache of trinkets and books in the loft of the barn, he begins to question everything and everyone he has known, including reality. Forced from his land and his home, Oswic takes his plough horse, the few fragments of truth from his life, and leaves Hægelfirth in search of the one person he believes can tell him of his past, the storyteller. But, it won’t be his past he needs to worry about when he starts to slip in and out of reality; seeing the future in strange visions. Believing he is witnessing the effects of the old gods’ magic on the world, Oswic sets off on a quest to destroy every piece of magical writing that exists in England. Will he succeed
Geochemical and rheological constraints on the dynamics of the oceanic upper mantle
Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution September 2007I provide constraints on mantle convection through observations of the rheology and
composition of the oceanic upper mantle. Convection cannot be directly observed, yet is
a fundamental part of the plate tectonic cycle. Relative motion among plates is accommodated
by localized deformation at their boundaries. I demonstrate that in the ductile regime,
strain localization occurs when different mineral phases are mixed together, limiting grain
annealing. Upper mantle flow is by dislocation creep, resulting in seismic anisotropy due
to mineral alignment. I use a shear zone in the Josephine Peridotite to quantify the relationship
between mineral orientation and shear strain, providing an improved framework
for the interpretation of seismic anisotropy. The upper mantle is generally assumed to be
homogeneous in composition. From detailed isotopic and chemical analyses of abyssal
peridotites from the Southwest Indian Ridge, I show that the mantle is heterogeneous at a
range of length-scales. Abyssal peridotites recovered at ocean ridges are generally interpreted
as the depleted residues of melt extraction. I find that melt-rock reaction is a significant
part of the melt extraction process, modifying the composition of the lithospheric
mantle. The generation of heterogeneous lithosphere provides a source for asthenospheric
heterogeneity, via subduction and mantle convection.This work has been supported financially by a variety of sources, including a Hollister

Bilateral intralobar pulmonary sequestration : a case report
Bronchopulmonary sequestration is a congenital lung malformation consisting of a non-functioning lung segment. Arterial supply to such a segment is found to be systemic rather than pulmonary, and by definition there is no communication with the tracheobronchial tree. It accounts for about 6% of all congenital pulmonary malformations. Bilateral bronchopulmonary sequestration is yet more uncommon. These malformations can be classified as either intralobar sequestration (the commoner type), or extralobar sequestration (in 14- 25%).peer-reviewe
From GIS to UAVs: Emerging Opportunities for Drone Support Services in Academic Libraries
In 2015, The Claremont Colleges Library purchased a drone for its Emerging Technology Loan program. At the time, Federal Aviation Administration regulations were still in their infancy in regards to drone use in public and for teaching and research –lending wasn’t even a consideration. After three years of waiting for the regulations to catch up with the demand, The Claremont Colleges Library GIS Specialist was able to pilot a drone lending program that circulates both the drone and the GIS Specialist for course integration. This paper outlines the history of GIS at The Claremont Colleges Library, its evolution toward drone services, and the successes, challenges, and lessons learned along the way
Raising the Dead: Clues to Type Ia Supernova Physics from the Remnant 0509-67.5
We present Chandra X-ray observations of the young supernova remnant (SNR)
0509-67.5 in the Large Magellanic Cloud (LMC), believed to be the product of a
Type Ia supernova (SN Ia). The remnant is very round in shape, with a distinct
clumpy shell-like structure. Our Chandra data reveal the remnant to be rich in
silicon, sulfur, and iron. The yields of our fits to the global spectrum
confirm that 0509-67.5 is the remnant of an SN Ia and show a clear preference
for delayed detonation explosion models for SNe Ia. We study the spectrum of
the single brightest isolated knot in the remnant and find that it is enhanced
in iron by a factor of roughly two relative to the global remnant abundances.
This feature, along with similar knots seen in Tycho's SNR, argues for the
presence of modest small-scale composition inhomogeneities in SNe Ia. The
presence of both Si and Fe, with abundance ratios that vary from knot to knot,
indicates that these came from the transition region between the Si- and
Fe-rich zones in the exploded star, possibly as a result of energy input to the
ejecta at late times due to the radioactive decay of 56Ni and 56Co. Two cases
for the continuum emission from the global spectrum were modeled: one where the
continuum is dominated by hydrogen thermal bremsstrahlung radiation; another
where the continuum arises from non-thermal synchrotron radiation. The former
case requires a relatively large value for the ambient density (~1 cm^-3).
Another estimate of the ambient density comes from using the shell structure of
the remnant in the context of dynamical models. This requires a much lower
value for the density (<0.05 cm^-3) which is more consistent with other
evidence known about 0509-67.5. We therefore conclude that the bulk of the
continuum emission from 0509-67.5 has a non-thermal origin.Comment: 34 pages, 9 figures (1 color), accepted to ApJ (10 June 2004 issue);

Modified Appleby Procedure with Arterial Reconstruction for Locally Advanced Pancreatic Adenocarcinoma: A Literature Review and Report of Three Unusual Cases.
BACKGROUND: Pancreatic body and tail ductal adenocarcinomas are often diagnosed with local vascular invasion of the celiac axis (CA) and its various branches. With such involvement, these tumors have traditionally been considered unresectable. The modified Appleby procedure allows for margin negative resection of some such locally advanced tumors. This procedure involves distal pancreatectomy with en bloc splenectomy and CA resection and relies on the presence of collateral arterial circulation via an intact pancreaticoduodenal arcade and the gastroduodenal artery to maintain prograde hepatic arterial perfusion. When the resultant collateral circulation is inadequate to provide sufficient hepatic and gastric arterial inflow, arterial reconstruction (AR) is necessary to supercharge the inflow. Herein, we review all reported cases of AR with modified Appleby procedures that we have identified in the literature, and we report our experience of three recent cases with arterial reconstruction including two cases with arterial bypasses not requiring interposition grafting.
METHODS: Perioperative and oncologic outcomes from our Institutional Review Board-approved database of pancreatic resections at the Thomas Jefferson University were reviewed. Additionally, PubMed search for cases of distal or total pancreatectomy with celiac axis resection and concurrent AR was performed.
RESULTS: From the literature, 12 reports involving 28 patients were identified of distal and total pancreatectomy with AR after CA resection. The most common AR in the literature, performed in 12 patients, was a bypass from the aorta to the common hepatic artery (CHA) using a variety of interposition conduits. In our institutional experience, patient #1 had a primary side-to-end aorto-CHA bypass, patient #2 had a primary end-to-end bypass of the transected distal CHA to the left gastric artery in the setting a replaced left hepatic artery, and patient #3 required an aortic to proper hepatic artery bypass with saphenous vein graft and portal venous reconstruction. All patients recovered from their operations without ischemic complications, and they are currently 16, 15, and 13 months post-op, respectively.
CONCLUSIONS: The criteria for resectability in patients with locally advanced pancreatic body and tail neoplasms are expanding due to increasing experience with AR in the setting of the modified Appleby procedure. When performing AR, primary arterial re-anastomosis may be considered preferable to interposition grafting as it decreases the potential for the infectious and thrombotic complications associated with conduits and it reduces the number of vascular anastomoses from two to one. Consideration must also be given to normal variant anatomy of the hepatic circulation during operative planning as the origin of the left gastric artery is resected with the CA. The modified Appleby procedure with AR, when used in appropriately selected patients, offers the potential for safe, margin negative resection of locally advanced pancreatic body and tail tumors
Evaluating Access and Barriers to Mindfulness Among Opioid-Dependent Patients in Bangor, Maine
Mindfulness has been shown to aid in addiction recovery and can help prevent relapse. The Family Medicine Center & Residency Program at Eastern Maine Medical Center (EMMC) in Bangor, Maine has provided mindfulness resources to their opioid-dependent patients; however, the center has no quantitative data on the current understanding and utilization of mindfulness techniques among this patient population. A survey tool was created and distributed to opioid-dependent patients in the clinic to identify barriers to practicing mindfulness. The collected data was submitted by one of the clinic providers in a grant proposal. Grant funding could go toward addressing these barriers.https://scholarworks.uvm.edu/fmclerk/1152/thumbnail.jp
Stellar Collisions and the Interior Structure of Blue Stragglers
Collisions of main sequence stars occur frequently in dense star clusters. In
open and globular clusters, these collisions produce merger remnants that may
be observed as blue stragglers. Detailed theoretical models of this process
require lengthy hydrodynamic computations in three dimensions. However, a less
computationally expensive approach, which we present here, is to approximate
the merger process (including shock heating, hydrodynamic mixing, mass
ejection, and angular momentum transfer) with simple algorithms based on
conservation laws and a basic qualitative understanding of the hydrodynamics.
These algorithms have been fine tuned through comparisons with the results of
our previous hydrodynamic simulations. We find that the thermodynamic and
chemical composition profiles of our simple models agree very well with those
from recent SPH (smoothed particle hydrodynamics) calculations of stellar
collisions, and the subsequent stellar evolution of our simple models also
matches closely that of the more accurate hydrodynamic models. Our algorithms
have been implemented in an easy to use software package, which we are making
publicly available (see http://vassun.vassar.edu/~lombardi/mmas/). This
software could be used in combination with realistic dynamical simulations of
star clusters that must take into account stellar collisions.Comment: This revised version has 37 pages, 13 figures, 4 tables; submitted to
