Civic Aspirations: Why Some Higher Education Faculty are Reconnecting Their Professional and Public Lives
In higher education today, most institutions reward faculty for such things as research productivity, course enrollment, and academic completion. There is little incentive for them to focus on educating students in their civic development. In spite of this, civic engagement programs are popping up across higher education, and faculty have played a critical role in initiating these programs on their campuses. Building on research by Harry Boyte and KerryAnn O'Meara. The Kettering Foundation seeks to make visible the motivations of these faculty. In this study for Kettering, based on faculty interviews, Claire Snyder-Hall explains this movement using Hannah Arendt's concept of "public happiness," a sense of fulfillment from engaging with others. Beyond higher education, this study has relevance across fields to practitioners struggling to integrate their civic aspirations into their professional work
Limiting Behaviour of the Mean Residual Life
In survival or reliability studies, the mean residual life or life expectancy
is an important characteristic of the model. Here, we study the limiting
behaviour of the mean residual life, and derive an asymptotic expansion which
can be used to obtain a good approximation for large values of the time
variable. The asymptotic expansion is valid for a quite general class of
failure rate distributions--perhaps the largest class that can be expected
given that the terms depend only on the failure rate and its derivatives.Comment: 19 page

Dissection of Melanogenesis with Small Molecules Identifies Prohibitin as a Regulator
SummaryBioactive compounds can be used to selectively modulate gene function. We utilized a chemical genetic approach to dissect the mammalian pigmentation pathway and identify protein regulators. We screened a tagged library of 1170 small molecules in a cell-based assay and discovered a class of pigment-enhancing chemicals. From this class we characterized the small molecule melanogenin. Using melanogenin bound to an affinity matrix and amino acid sequencing, we identified the mitochondrial protein, prohibitin, as an intracellular binding target. Studies employing siRNA demonstrate that prohibitin is required for melanogenin to exert its propigmentary effects and reveal an unsuspected functional role for this protein in melanin induction. This represents a mechanism by which propigmentary signals are transduced and ultimately provides a potential target for the treatment of pigmentary disorders
Improved Satellite Robustness Through Application of Erosion Resistance and High Emissivity Coatings
Spacecraft can experience charging throughout operation due to high flux of incident electrons (ex. during geomagnetic substorm). As a result, different materials/components may experience a range of potentials which may lead to plasma-induced arcs, damaging spacecraft components. 54% of spacecraft failures are due to enhancement of radiation belt particles and magnetospheric plasma that cause charging/discharing Current space charge mitigation technologies: Metallic coatings System chassis ground leads to as many surfaces as possible Not effective in severe sub-storm conditions and do not enable local application of coatin
Exact master equation for a noncommutative Brownian particle
We derive the Hu-Paz-Zhang master equation for a Brownian particle linearly
coupled to a bath of harmonic oscillators on the plane with spatial
noncommutativity. The results obtained are exact to all orders in the
noncommutative parameter. As a by-product we derive some miscellaneous results
such as the equilibrium Wigner distribution for the reservoir of noncommutative
oscillators, the weak coupling limit of the master equation and a set of
sufficient conditions for strict purity decrease of the Brownian particle.
Finally, we consider a high-temperature Ohmic model and obtain an estimate for
the time scale of the transition from noncommutative to ordinary quantum
mechanics. This scale is considerably smaller than the decoherence scale.Comment: Latex file, 28 pages, Published versio
First observation of Li ground state
The ground state of neutron-rich unbound Li was observed for the first
time in a one-proton removal reaction from Be at a beam energy of 53.6
MeV/u. The Li ground state was reconstructed from Li and two
neutrons giving a resonance energy of 120 keV. All events
involving single and double neutron interactions in the Modular Neutron Array
(MoNA) were analyzed, simulated, and fitted self-consistently. The three-body
(Li+) correlations within Jacobi coordinates showed strong
dineutron characteristics. The decay energy spectrum of the intermediate
Li system (Li+) was described with an s-wave scattering length
of greater than -4 fm, which is a smaller absolute value than reported in a
previous measurement.Comment: Accepted for publication in Phys. Rev. C as a Rapid Communicatio
R-Parity Violation at HERA ?
We examine the possibility that the high-Q^2 events seen at HERA are due to
the production and decay of squarks of R-parity violating supersymmetry. The
relevant R-parity violating coupling(s) is identified and shown to lie between
0.03 and 0.26. Consequences of such a coupling at other experiments, such as
the LEP and Tevatron, are discussed
Soliton molecules in trapped vector Nonlinear Schrodinger systems
We study a new class of vector solitons in trapped Nonlinear Schrodinger
systems modelling the dynamics of coupled light beams in GRIN Kerr media and
atomic mixtures in Bose-Einstein condensates. These solitons exist for
different spatial dimensions, their existence is studied by means of a
systematic mathematical technique and the analysis is made for inhomogeneous
media
Higher Education Exchange: 2012
This annual publication serves as a forum for new ideas and dialogue between scholars and the larger public. Essays explore ways that students, administrators, and faculty can initiate and sustain an ongoing conversation about the public life they share.The Higher Education Exchange is founded on a thought articulated by Thomas Jefferson in 1820: "I know no safe depository of the ultimate powers of the society but the people themselves; and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is not to take it from them, but to inform their discretion by education."In the tradition of Jefferson, the Higher Education Exchange agrees that a central goal of higher education is to help make democracy possible by preparing citizens for public life. The Higher Education Exchange is part of a movement to strengthen higher education's democratic mission and foster a more democratic culture throughout American society.Working in this tradition, the Higher Education Exchange publishes interviews, case studies, analyses, news, and ideas about efforts within higher education to develop more democratic societies
