Enforcing The Nuclear Nonproliferation Regime: The Legality Of Preventive Measures, Cristian Defrancia Jan 2012

Enforcing The Nuclear Nonproliferation Regime: The Legality Of Preventive Measures, Cristian Defrancia

Vanderbilt Journal of Transnational Law

Efforts to limit the proliferation of nuclear weapons and nuclear-weapons-related technology have increasingly involved economic, technological, and military forms of coercion implemented in an environment of low-level conflict. Coercive counterproliferation measures have included a range of actions, including targeted economic sanctions, industrial sabotage, cyber attacks, targeted killings, and military strikes. While the nonproliferation obligations of states are well-established under relevant treaties, state practice, and the international monitoring system of the International Atomic Energy Agency (IAEA), norms relating to the enforcement of those obligations are not clearly defined in legal instruments. This Article reviews the legality of prevention and enforcement measures …

Top-Down Estimate Of Dust Emissions Through Integration Of Modis And Misr Aerosol Retrievals With The Geos-Chem Adjoint Model, Jun Wang, Xiaoguang Xu, Daven K. Henze, Jing Zeng, Qiang Ji, Si-Chee Tsay, Jianping Huang

Department of Earth and Atmospheric Sciences: Faculty Publications

Predicting the influences of dust on atmospheric composition, climate, and human health requires accurate knowledge of dust emissions, but large uncertainties persist in quantifying mineral sources. This study presents a new method for combined use of satellite-measured radiances and inverse modeling to spatially constrain the amount and location of dust emissions. The technique is illustrated with a case study in May 2008; the dust emissions in Taklimakan and Gobi deserts are spatially optimized using the GEOSChem chemical transport model and its adjoint constrained by aerosol optical depth (AOD) that are derived over the downwind dark-surface region in China from MODIS …


An Analysis Of Laboratory Inspections At The University Of Kentucky, Rachel Eldridge Jan 2012

An Analysis Of Laboratory Inspections At The University Of Kentucky, Rachel Eldridge

MPA/MPP/MPFM Capstone Projects

Recent news stories about laboratory accidents in which students were severely injured and killed have brought much-needed attention to lab safety. Creating a positive safety climate on college and university campuses is very important in reducing accidents. At the University of Kentucky, all laboratories are inspected once every year, and the results are recorded in a lab inspection database. These data include the department, building, lab classification, type of violation, room number, and the name of the PI (Principal Investigator). I want to analyze inspections to find out whether department and the lab classification are significant in looking at violations. …


Critical Pedagogy In The Classroom: Library Instruction That Gives Voice To Students And Builds A Community Of Scholars, Michelle Reale Jan 2012

Critical Pedagogy In The Classroom: Library Instruction That Gives Voice To Students And Builds A Community Of Scholars, Michelle Reale

Library Faculty Scholarship

When librarians apply critical pedagogy in a classroom, they can both impart knowledge and ignite breakthrough thinking among students. By partnering with professors and decentralizing the power in the classroom, librarians can tap into knowledge that students already possess and encourage them to express their own ideas. This article describes the process in a 200-level literature interpretation course taught primarily to English majors at Arcadia University.


Changing The Conversation In Education Law: Political Geography And Virtual Schooling Book Review Essay, Aaron J. Saiger Jan 2012

Changing The Conversation In Education Law: Political Geography And Virtual Schooling Book Review Essay, Aaron J. Saiger

Faculty Scholarship

In Five Miles Away, A World Apart, James E. Ryan concludes that the educational reforms of the hour, school accountability and school choice, will exacerbate rather than undermine the systematic educational advantages enjoyed by wealthier Americans. Paul Peterson, in his Saving Schools, argues that increasingly centralizing American schools have become sufficiently centralized that, as a labor-intensive industry, few productivity gains are available from governance reform, even as demand escalates for the customization of education to individual needs. Both volumes therefore pin their hopes for change upon political geography-the relationship between people and educational institutions in space. Ryan argues that changing …

Breeding Biology And Bee Guild Of Douglas’ Dustymaiden, Chaenactis Douglasii (Asteraceae, Helenieae), James H. Cane, Byron Love, Katharine A. Swoboda-Bhattarai

Department of Entomology: Faculty Publications

Douglas’ dustymaiden, Chaenactis douglasii (Hook.) Hook. & Arn., is a widespread, inconspicuous, short-lived perennial wildflower that blooms in early summer and is found in basin sagesteppe to upper montane areas throughout the U.S. Intermountain West. The species is proving practical to grow for seed and is expected to be used for western rangeland rehabilitation. Through manual pollination experiments, C. douglasii was found to be only weakly self-fertile; 15% of flowers from geitonogamy and autogamy treatments yielded filled achenes. In contrast, 57% of outcrossed flowers produced achenes filled with endosperm, with every capitulum yielding some fertile seeds. Freely visited flowers from …

The European Corn Borer And Bt Corn In The United States, Blair D. Siegfried, Richard L. Hellmich Jan 2012

The European Corn Borer And Bt Corn In The United States, Blair D. Siegfried, Richard L. Hellmich

Department of Entomology: Faculty Publications

The European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae) has been a major pest of corn and other crops in North America since its accidental introduction nearly a hundred years ago. Wide adoption of transgenic corn hybrids that express toxins from Bacillus thuringiensis, referred to as Bt corn, has suppressed corn borer populations and reduced the pest status of this insect in parts of the Corn Belt. Continued suppression of this pest, however, will depend on managing potential resistance to Bt corn, currently through the high-dose refuge (HDR) strategy. In this review, we describe what has been learned with …


A Molecular Key For The Identification Of Blow Flies In Southeastern Nebraska, Upeka Samarakoon, Steven R. Skoda, Frederick P. Baxendale, John E. Foster Jan 2012

A Molecular Key For The Identification Of Blow Flies In Southeastern Nebraska, Upeka Samarakoon, Steven R. Skoda, Frederick P. Baxendale, John E. Foster

Department of Entomology: Faculty Publications

Immature blow flies (Calliphoridae) are typically the first colonizers of cadavers. Identification of the early instars using traditional, morphology-based keys is difficult because of their small size, similarity, and simplicity in external morphology. Information derived from molecular genetic data would augment the accurate identification of immature flies. Nine species of blow flies commonly found in southeastern Nebraska were used to examine the utility of molecular-based keys. Polymerase chain reaction–restriction fragment length polymorphisms (PCR–RFLP) were investigated with 10 common, inexpensive, restriction enzymes from an amplicon of approximately 1500 bp spanning the mitochondrial cytochrome oxidase I gene. A simple molecular taxonomic key, …


Factors Influencing Web Tenure In A Tropical Spider And Comparison Between Forest And Non-Forest Habitats, Daniella R. Barraza Jan 2012

Factors Influencing Web Tenure In A Tropical Spider And Comparison Between Forest And Non-Forest Habitats, Daniella R. Barraza

Scripps Senior Theses

Webs are fundamental to the ecology of Nephila clavipes, the golden orb-weaver spider, because they serve as sites for prey capture, reproduction, competition, predation, and parasitism. In addition to the presence of the female N. clavipes, males and kleptoparasites reside on the web in varying numbers. Webs are also found in clusters with conspecific females. Web site selection and length of web tenure is a behavioral decision vital to the spider’s fitness and the ecology of her species. I conducted a field census to quantify these factors and analyze their influence on web tenure, compare web ecology between a forest …


Adenine Uracil Guanine: An Exploration Of Certainty In Science, Alicia M. Hendrix Jan 2012

Adenine Uracil Guanine: An Exploration Of Certainty In Science, Alicia M. Hendrix

Scripps Senior Theses

Collaboration and communication between conventionally diverse fields can allow for deeper understanding and clearer analysis of the concepts within each. Two fields traditionally seen as dichotomous are those of art and science. Historically they approach problems in opposite ways. However, I would argue that they in fact investigate very similar questions, hoping to discover the ways that the world works. It makes sense, then, that historically these fields have sometimes been able to interact. Artists have engaged with science by creating work through scientific processes including crossbreeding flowers, genetically modifying organisms, and sequencing nucleotides. Others have referenced scientific ideas, like …


Review Of Griffith Taylor – Visionary Environmentalist Explorer By Carolyn Strange And Alison Bashford, Christina E. Dando Jan 2012

Review Of Griffith Taylor – Visionary Environmentalist Explorer By Carolyn Strange And Alison Bashford, Christina E. Dando

Geography and Geology Faculty Publications

Few would argue the inherently visual nature of geography, our use (and love of) maps, our emphasis on fieldwork and observation. Carolyn Strange and Alison Bashford’s biography Griffith Taylor: Visionary, Environmentalist, Explorer is as much a visual biography as a textual one, drawing on extensive visual materials as well as diaries and letters. Through images and texts, Strange and Bashford create a portrait of a complicated geographer, revealing a leading geographer of the twentieth century whose contributions cover the spectrum and the globe.

Mutation At The Human D1s80 Minisatellite Locus, Kuppareddi Balamurugan Jan 2012

Mutation At The Human D1s80 Minisatellite Locus, Kuppareddi Balamurugan

Faculty Publications

Little is known about the general biology of minisatellites. The purpose of this study is to examine repeat mutations from the D1S80 minisatellite locus by sequence analysis to elucidate the mutational process at this locus. This is a highly polymorphic minisatellite locus, located in the subtelomeric region of chromosome 1. We have analyzed 90,000 human germline transmission events and found seven (7) mutations at this locus. The D1S80 alleles of the parentage trio, the child, mother, and the alleged father were sequenced and the origin of the mutation was determined. Using American Association of Blood Banks (AABB) guidelines, we found …

The Influence Of Biochar Production On Herbicide Sorption Characteristics, Sharon A. Clay, Douglas D. Malo Jan 2012

The Influence Of Biochar Production On Herbicide Sorption Characteristics, Sharon A. Clay, Douglas D. Malo

Agronomy, Horticulture and Plant Science Faculty Publications

Biochar is the by-product of a thermal process conducted under low oxygen or oxygen-free conditions (pyrolysis) to convert vegetative biomass to biofuel (Jha et al., 2010). There are a wide variety of end-products that can be manufactured depending on processing parameters and initial feedstocks (Bridgewater, 2003). The pyrolytic process parameters such as temperature, heating rate, and pressure can change the recovery amounts of each end-product, energy values of the bio-oils, and the physico-chemical properties of biochar (Yaman, 2004).


A Direct D-Bar Reconstruction Algorithm For Recovering A Complex Conductivity In 2d, Sarah J. Hamilton, C. N. L. Herrera, J. L. Mueller, A. Von Herrmann Jan 2012

A Direct D-Bar Reconstruction Algorithm For Recovering A Complex Conductivity In 2d, Sarah J. Hamilton, C. N. L. Herrera, J. L. Mueller, A. Von Herrmann

Mathematics, Statistics and Computer Science Faculty Research and Publications

A direct reconstruction algorithm for complex conductivities in W2, ∞(Ω), where Ω is a bounded, simply connected Lipschitz domain in R2 , is presented. The framework is based on the uniqueness proof by Francini (2000 Inverse Problems 6 107–19), but equations relating the Dirichlet-to-Neumann to the scattering transform and the exponentially growing solutions are not present in that work, and are derived here. The algorithm constitutes the first D-bar method for the reconstruction of conductivities and permittivities in two dimensions. Reconstructions of numerically simulated chest phantoms with discontinuities at the organ boundaries are included.
