The Penguins' Revolution: An Analysis Of Student Response To The Multi-Dimensional Chilean Educational Crisis, Abigail Hall

Honors Theses

Through exploration and analysis of economic, historical and political factors stemming from the authoritarian period (1973-1990) to the present day, this project offers an interdisciplinary explanation of the emergence of the "Penguin's Revolution" in Chile. In May-June 2006, 700,000 high school students paralyzed the Chilean education system by protesting in the streets, taking over schools and not attending classes. Students organized under the Coordinating Assembly of Secondary Students (ACES) demanded that the government take responsibility for providing universal high quality and equal education. The roots of student discontent lie in the multi-dimensional education crisis, generated by the semi-privatized, decentralized educational …

Pressure Perturbation Calorimetry And Guest-Host Chemistry Of Ndmg And N-Map With P-Sulfonatocalix[6]Arene, Cassandra Newell

Honors Theses

The aim of this project is to provide an explanation for recently obtained binding constants for two similar guest molecules, NDMG and N-MAP, with a p-sulfonatocalix[6]arene host in ammonium acetate buffer. This work was done primarily using pressure perturbation calorimetry, which is a technique that determines the coefficient of thermal expansion, α, which is in turn related to the solute molecule's effect on the order of the surrounding water molecules. A series of experiments were designed to test the effects of suspected confounding variables on the validity of PPC data. PPC was then used to study NDMG and N-MAP in …

Search For Novel Molecular Species Formed By Cold Rydberg Atoms In A Magneto-Optical Trap, Alexander Gill

Honors Theses

This describes a search for novel ultra-long-range molecular resonances between rubidium Rydberg atoms in a magneto-optical trap (MOT). We use the technique of photoassociative spectroscopy by directly scanning the wavelength of our Rydberg excitation laser about a 5p3/2 - 90p3/2 transition in a weak electric field and by scanning mm-waves about a 39sl/2 - 39p3/2 transition. The results of both of these surveys are inconclusive.

Diode Lasers For Use In Experiments On Cold Rydberg Atoms, Bill Whitledge

Honors Theses

This project was to measure the atomic density of (85)Rb atoms in a magneto optical trap using a low-intensity probe laser. Additionally, a dark spontaneous force optical trap was constructed in an attempt to boost the trap density. The dark spot failed to appreciably increase the overall trap density (which remained steady at - N = 10^10 atoms/cm^3) but it did increase the density of dark-state atoms in the trap by an order of magnitude. This is a useful result since many experiments on cold Rydberg atoms involve exciting atoms starting in the ground state rather than the first excited …

Interactions Of Electrons And Rydberg Atoms In Ultra-Cold Plasmas, Cristian Vesa

Honors Theses

This thesis discusses an experimental technique for investigating electron temperature control by Rydberg atoms in ultra-cold plasmas. The objective we set ourselves was twofold. Firstly, we sought to gain an insight into the processes whereby the creation of Rydberg atoms within the plasma lengthens the lifetime of the plasma. To this end, we created the plasma using a Littman dye laser and subsequently, at a variable time delay, we excited neutral atoms in the plasma to specific Rydberg states using a narrow bandwidth pulsed dye laser. Secondly, we employed radio-frequency (rf) electric fields to excite electron oscillations within the plasma …

Photochemical Generation And Intramolecular Chemistry Of Β-Alkoxycarbenes, Kimberly Graves

Honors Theses

The photolytic phenanthrene-based precursors for both β-methoxycarbene and β-ethoxycarbene were synthesized with and without a deuterium label attached to the a carbon. The incorporation of this deuterium label allowed distinction between a 1, 2-H shift and a 1, 2-O shift pathway to the respective alkyl vinyl ether, without the influence of a primary kinetic isotope effect. Photolyses of these precursors gave rearrangement products of the expected β-alkoxycarbenes. In the case of β-methoxycarbene, no methyl vinyl ether was observed due to its volatility. However, the appearance of aldehyde peaks in the NMR spectra, from an apparent further rearrangement to acetaldehyde through …

Hamiltonian Constraint Analysis Of Vector Field Theories With Spontaneous Lorentz Symmetry Breaking, Nolan L. Gagne

Honors Theses

Recent investigations of various quantum-gravity theories have revealed a variety of possible mechanisms that lead to Lorentz violation. One of the more elegant of these mechanisms is known as Spontaneous Lorentz Symmetry Breaking (SLSB), where a vector or tensor field acquires a nonzero vacuum expectation value. As a consequence of this symmetry breaking, massless Nambu-Goldstone modes appear with properties similar to the photon in Electromagnetism. This thesis considers the most general class of vector field theories that exhibit spontaneous Lorentz violation-known as bumblebee models-and examines their candidacy as potential alternative explanations of E&M, offering the possibility that Einstein-Maxwell theory could …

Reactions Of Atomic Carbon With Acid Chlorides, Daniel B. Herrick

Honors Theses

This thesis is the first report of reactions of atomic carbon with acid chlorides. Carbon is known to react with phosgene to afford dichlorocarbene. We report a similar reaction with carbon and acid chlorides, generating alkylchlorocarbenes. We examine both the nature of the carbene products generated through deoxygenation and the general reactivity of carbon with the acid chlorides. We report two ways in which carbon reacts with acid chlorides. First, as expected from prior work with phosgene, carbon deoxygenates the carbonyl group yielding alkylchlorcarbenes, which rearrange as expected. Second, carbon abstracts the chlorine, and generates the acyl radical, which, in …

Separating People And Wildlife: Zoning As A Conservation Strategy For Large Carnivores, Courtney L. Larson

Honors Theses

Large carnivores are some of the world’s most difficult species to conserve because of their large spatial requirements, low population density, and high potential for conflict with humans. However, large carnivores are valuable for ecological, cultural, and ethical reasons. Carnivore management can take a wide variety of forms, including translocation, sterilization, livestock compensation programs, regulated hunting, improved livestock husbandry practices, and zoning, among others. The objective of this thesis was to conduct a comparative analysis of examples of zoning from around the world to examine whether it is an effective carnivore management strategy.

Diffeomorphism Invariance In General Relativity, John P. Chung

Honors Theses

Einstein's general relativity is a geometrical theory of gravity in which the effects of gravity are due to the curvature of space and time. In contrast, all of the other fundamental particle interactions are described as quantum field theories that are invariant under gauge transformations. In efforts to unify gravity with these other particle theories, it is desirable to reexpress Einstein's general relativity as a gauge theory. The gauge symmetry in Einstein's theory can be identified as invariance under diffeomorphism transformations. This work examines the nature of this symmetry, how it is implemented, and how it behaves as a gauge …

Effect Of Observed Biological And Non-Biological Movement On Human Action And Coordination, Walter L. Campbell

Honors Theses

Recently, it has been demonstrated that an individual’s rhythmic limb movements exhibit greater variability when viewing spatially incongruent biological limb movements, but not when viewing spatially incongruent non-biological movements. Some researchers have concluded that a ‘mirror-neuron system’ might mediate the intrinsic bidirectional link between perception and action underlying interpersonal, but not environmental, coordination (e.g., Kilner et al., 2003; Tognoli et al., 2007). The current study aimed to: 1) contest this recent finding; and 2) demonstrate that the self-organized entrainment processes of coupled oscillators can explain the differing influences of biological and non-biological movements. In the first experiment, participants intentionally coordinated …

Phosphorus Primer For Maine’S Lakes, Lindsay B. Philips

Honors Theses

Phosphorus plays a major role in aquatic systems and the life that they support. It is a macronutrient that constitutes 0.5lf microorganisms and zooplankton by mass. Phosphorus is of great importance in terrestrial, agricultural, and plant systems as a macronutrient, and when it comes to aquatic systems, we tend to look at phosphorus in terms of its influence on lake primary productivity. Lakes are often phosphorus sinks because they are maintained by hydrological sources that are capable of causing nutrient influx. To understand phosphorus cycling in lake systems, it is important to consider the many sources and forms of phosphorus …

Competition Or Community? Manifest And Unexpressed Functions Of The No Child Left Behind Act Of 2001, Sara Benjamin

Honors Theses

Any contemporary discussion of the American education system inevitably includes a discussion of current federal policy as set out in The No Child Left Behind Act of 2001 (NCLB). Signed into law on January 8, 2002, NCLB has sparked tremendous controversy in the field of education. Although the title would suggest otherwise, NCLB does not aim to make sure no child is left behind. Instead, one might argue that it aims to provide quantifiable measures of comparison so as to allow the U.S. to assert educational and economic dominance in the global community. Thus, we can see a distinction between …
