Legitimacy, Innovation, And Harmonization: Precursors To Operationalizing Biofuels Sustainability Standards, Jody M. Endres

Southern Illinois University Law Journal

How to balance land uses to sustainably feed, clothe, and power a burgeoning population aspiring to western lifestyles will be a profound, if not the most profound, challenge to policymakers in the 21st century.  And, climate change’s unpredictable effects on natural systems will exacerbate already complex, uncertain, and contentious land use decision-making.  While biomass-based energy policies gained momentum throughout the 2000s as one way to reduce greenhouse gas emissions, assumptions about biofuels’ environmental and societal benefits are beginning to come under closer scrutiny.  In response, public laws have incorporated varying forms of sustainability considerations.  Many private standards have emerged, however, …

Collaborative Online Writing Assignments To Foster Active Learning, Richard F. Olivo

Neuroscience: Faculty Publications

To help students master the content of a neurophysiology course, they were asked to participate in collaborative writing projects. In the first two years, students contributed to a class wiki by summarizing one lecture and editing summaries of several others. In the second two years, students worked in teams of three or four to write a series of illustrated chapters spanning the entire semester. The second assignment kept students more engaged than the wiki project, and although they found it a significant amount of work, they also believed that it helped them learn the subject matter. Working in teams, however, …

Electroluminescence From Zno Nanostructure Synthesizes Between Nanogap, Cheng Jiang

Master's Theses (2009 -)

This thesis presents the investigation of a nanoscale light-emitting diode (LED) device. The nanoscale LED has a great potential to be used as a light source for biomedical screening and fluorescence lifetime spectroscopy. It can also be developed to a single photon emitter for the application of quantum computing. The nano-LED has the electrical structure of a metal-semiconductor-metal (MSM) junction. The MSM junction has been formed on the nanogap device that is fabricated on a SOI wafer by optical lithography and KOH solution silicon etching. The Ni evaporated on the surface of the nanogap device performs the metal contact for …

The Importance Of Host Plant Limitation For Caterpillars Of An Arctiid Moth (Platyprepia Virginalis) Varies Spatially, Richard Karban, Patrick Grof-Tisza, John L. Maron, Marcel Holyoak

Biological Sciences Faculty Publications

Spatial dynamic theories such as source–sink models frequently describe habitat-specific demographies, yet there are surprisingly few field studies that have examined how and why interacting species vary in their dynamics across multiple habitat types. We studied the spatial pattern of interaction between a chewing herbivore and its primary larval host plant in two habitat types. We found that the interaction between an arctiid caterpillar (Platyprepia virginalis) and its host (Lupinus arboreus) differed in wet vs. upland dry habitats, as did yearly population dynamics for the caterpillar. In upland sites, there was a strong positive relationship between …

Neo-Allopatry And Rapid Reproductive Isolation, Daniel Montesinos, Gilberto Santiago, Ragan M. Callaway

Biological Sciences Faculty Publications

Over the past 3 centuries, many species have been dispersed beyond their natural geographic limits by humans, but to our knowledge, reproductive isolation has not been demonstrated for such neo-allopatric species. We grew seeds from three species of Centaurea (Centaurea solstitialis, Centaurea calcitrapa, and Centaurea sulphurea) that are native to Spain and have been introduced into California, and we tested to what extent seed production was affected by pollen source. Compared with within-population crosses, seed production decreased by 52% and 44%, respectively, when C. solstitialis and C. sulphurea from California were pollinated with conspecific pollen from native populations in Spain. …

Gametes: A Fast, Direct Algorithm For Generating Pure, Strict, Epistatic Models With Random Architectures, Ryan J. Urbanowicz, Jeff Kiralis, Nicholas A. Sinnott-Armstrong, Tamra Heberling, Jonathan M. Fisher, Jason H. Moore

Dartmouth Scholarship

Background: Geneticists who look beyond single locus disease associations require additional strategies for the detection of complex multi-locus effects. Epistasis, a multi-locus masking effect, presents a particular challenge, and has been the target of bioinformatic development. Thorough evaluation of new algorithms calls for simulation studies in which known disease models are sought. To date, the best methods for generating simulated multi-locus epistatic models rely on genetic algorithms. However, such methods are computationally expensive, difficult to adapt to multiple objectives, and unlikely to yield models with a precise form of epistasis which we refer to as pure and strict. Purely and …

Current Status And Long-Term Trends In Water Quality And Living Resources In The Virginia Tributaries And Chesapeake Bay Mainstem From 1985 Through 2011, Daniel M. Dauer, Harold G. Marshall, John R. Donat, Michael F. Lane, Suzanne C. Doughten, Cindy Johnson

Status and Trends for Virginia Chesapeake Bay

The period prior to the implementation of the Chesapeake Bay Monitoring Program was characterized by a marked decline in the water quality of the Chesapeake Bay. The disappearance of submerged aquatic vegetation in certain regions of the Bay, declines in the abundance of some commercially and recreationally important species, increases in the incidence of low dissolved oxygen events, changes in the Bay's food web, and other ecological problems have been related to the deteriorating water quality (e.g. USEPA, 1982,1983;Officer et al.,1984; Orth and Moore, 1984). The results of concentrated research efforts in the late 1970s and early 1980s stimulated the …

Professional Learning Communities’ Impact On Science Teacher Classroom Practice In A Midwestern Urban School District, Dan Carpenter

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of this reputation-based, multiple-site case study was to explore professional learning communities’ impact on teacher classroom practice. The goal of this research was to describe the administrator and teachers’ perceptions with respect to professional learning communities as it related to teacher practice in their school. Educators and administrators were asked what types of practices teachers took from collaborative professional learning communities and tried in their classrooms.

This reputation-based, multiple-site case study was important to Nebraska educators because many school districts had implemented professional learning communities in a variety of forms in the schools. There had been little, if …

Impacts Of Climate Change On The Surface Water Balance Of The Central United States, 1984–2007, Bo Dong

School of Natural Resources: Dissertations, Theses, and Student Research

The climate system and the hydrologic cycle are strongly connected with each other. Understanding the interactions between these two systems is important, since variations in climate can trigger extensive changes in the hydrologic cycle, with significant impacts on agriculture, ecosystems, and society. Observations over the central U.S. in recent decades show numerous changes in climatic variables. This includes decreases in cloud cover and wind speed, increases in air temperature, and seasonal shifts in precipitation rate and rain/snow fraction. To assess the impacts of these variations in climate on the regional water cycle, a terrestrial ecosystem/land surface hydrologic model (Agro-IBIS) is …

The Reminiscence Effect In Autobiographical Memory And Tests Of Its Prominent Accounts, Justin T. Coleman

Department of Psychology: Dissertations, Theses, and Student Research

The reminiscence effect, in which people aged 40 and over remember more autobiographical memories from between ages 10 to 30 than from adjacent periods, producing a “bump” in lifespan distributions, is a highly robust effect. When it was discovered to occur for highly positive emotional memories, but not negative ones, the cultural life script account of reminiscence was proposed. The cultural life script account asserts that individuals possess scripts for important events in the normative life that structure autobiographical recall. The reminiscence effect is explained by the fact that in life scripts, positive events have highly prescribed timings and cluster …

Organellar Signaling Expands Plant Phenotypic Variation And Increases The Potential For Breeding The Epigenome, Roberto De La Rosa Santamaria

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

MUTS HOMOLOGUE 1 (MSH1) is a nuclear gene unique to plants that functions in mitochondria and plastids, where it confers genome stability. Phenotypic effects of MSH1 down- regulation were studied in sorghum inbreed line Tx430 and Arabidopsis ecotype Columbia-0, with the hypothesis that RNAi suppression of MSH1 triggers retrograde signaling from organelles to the nucleus, alters the epigenome, and derives heritable phenotypic variation suitable for artificial selection. An array of morphological traits and metabolic pathways was detected, including leaf variegation, male sterility and dwarfism, associated with altered gibberellic acid metabolism, higher levels of reactive oxygen species (ROS), and decreased synthesis …

Novelty Interactions Between Herbivorous Fish And Sargassum: Insight Into Macroalgal Phase Shifts, Christopher Pickens

Independent Study Project (ISP) Collection

Herbivores play a key role in the maintenance of algal and coral communities. A reduction in herbivory has been shown to result in a shift to a macroalgae dominated system, which can have significant effects on the biodiversity and restorative capabilities of coral reefs. Several studies have been done to better understand how herbivorous communities respond to macroalgae. These have shown that only certain herbivorous taxa are capable of removing macroalgae and there are several factors (depth, density, etc.) that affect the susceptibility of macroalgae to herbivory. However, few studies have yet to determine if the novelty of the resource …

Confronting The Crisis In Scientific Publishing: Latency, Licensing And Access, Jorge L. Contreras

Joint PIJIP/TLS Research Paper Series

The serials crisis in scientific publishing can be traced to the long duration of copyright protection and the assignment of copyright by researchers to publishers. Over-protection of scientific literature has enabled commercial publishers to increase subscription rates to a point at which access to scientific information has been curtailed with negative social welfare consequences. The uniformity costs imposed by such over-protection can be addressed by tailoring intellectual property rights, either through legal change or private ordering.

Current open access channels of distribution offer alternative approaches to scientific publishing, but neither the Green OA self-archiving nor the Gold OA author-pays models …

Cox Inhibitors Indomethacin And Sulindac Derivatives As Antiproliferative Agents: Synthesis, Biological Evaluation, And Mechanism Investigation, Snigdha Chennamaneni, Bo Zhong, Rati Lama, Bin Su

Chemistry Faculty Publications

Cyclooxygenase (COX) inhibitors Indomethacin and its structural analogs Sulindac exhibit cell growth inhibition and apoptosis inducing activities in various cancer cell lines via COX independent mechanisms. In this study, the molecular structures of Indomethacin and Sulindac were used as starting scaffolds to design novel analogs and their effects on the proliferation of human cancer cells were evaluated. Compared to Indomethacin and Sulindac inhibiting cancer cell proliferation with IC50s of more than 1 mM, the derivatives displayed significantly increased activities. Especially, one of the Indomethacin analogs inhibited the growth of a series of cancer cell lines with IC50s around 0.5 μM–3 …

Ceg 4110/6110-01: Introduction To Software Computer Engineering, Nikolaos Bourbakis

Computer Science & Engineering Syllabi

This course is concerned with the techniques of designing and constructing large programs. Some of the required basic concepts necessarily have to be developed using small programs as examples. To this extent, we also study programming-in-the-small. The overall objectives are to present an overview of issues in the development of software, to discuss terminology, to illustrate via example case studies, and to give sufficiently detailed advice on how to develop quality software and present a way of communication via UML. Hands-on experience is emphasized through the use of homework and a class project.

Collected Faculty Scholarship

A mouse model with compromised mitochondrial fatty acid synthesis has been engineered in order to assess the role of this pathway in mitochondrial function and overall health. Reduction in the expression of mitochondrial malonyl CoA-acyl carrier protein transacylase, a key enzyme in the pathway encoded by the nuclear Mcat gene, was achieved to varying extents in all examined tissues employing tamoxifen-inducible Cre-lox technology. Although affected mice consumed more food than control animals, they failed to gain weight, were less physically active, suffered from loss of white adipose tissue, reduced muscle strength, kyphosis, alopecia, hypothermia and shortened lifespan. The Mcat-deficient phenotype …

Liposome Encapsulation Of A Photochemical No Precursor For Controlled Nitric Oxide Release And Simultaneous Fluorescence Imaging, Alexis D. Ostrowski, Brian F. Lin, Matthew V. Tirrell, Peter C. Ford

Chemistry Faculty Publications

Described are photochemical studies of the nitric oxide precursors, trans-Cr(L)(ONO)(2)(+) (L = cyclam = 1,4,8,11-tetraazacyclotetradecane, CrONO, or L = mac = 5,7-dimethyl-6-anthracenylcyclam, mac-CrONO) encapsulated in phosphatidylcholine liposomes. The liposomes provide a means to maintain a localized high concentration of NO releasing complexes and are easily modified for in vivo targeting through self-assembly. Steady, controlled release of NO is seen after photolysis of the liposome-encapsulated CrONO as compared to the burst of NO release seen by the unencapsulated complex in oxygenated solutions. The quantum yields for photochemical NO release from liposome-encapsulated CrONO and mac-CrONO were determined in both oxygenated and anoxic …

Discrete Arginine Topologies Guide Escape Of Miniature Proteins From Early Endosomes To The Cytoplasm, Jacob S. Appelbaum

Yale Medicine Thesis Digital Library

Polypeptides and peptide mimetics sample a wide chemical space with broad potential to modulate cellular function, but their application to cytoplasmic targets is limited because when added to cells their cytosolic concentration remains low. This limitation is due to a diffusion barrier (the plasma membrane) and absence of dedicated import machinery. Highly cationic peptides and proteins sometimes gain cytosolic access, but how they do so is not well understood. Using a small library of cationic miniature proteins, I probe the influence of positive charge number and orientation on the ability the miniature protein to access the cytoplasm. Using a novel …
