Ecology And Management Of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) In Southern Pine Forests, T. D. Schowalter

Faculty Publications

Bark beetles (Coleoptera: Curculionidae: Scolytinae) have been an important historic and current factor affecting pine forest production in the southern United States. Although tree mortality to bark beetles often detracts from forest management goals, the natural role of bark beetles is canopy opening, thinning, and diversification of stand structure and composition, effects that contribute to some ecosystem services in forests managed for multiple uses. Strategies to prevent bark beetle outbreaks exploit their sensitivity to host tree spacing and reliance on pheromones to attract sufficient numbers to overwhelm tree defenses. Tree species selection at planting or through selective thinning can favor …

Caffey, Kevin R. Carman, John W. Fleeger, Samantha B. Joye, Qianxin Lin, Edward Maltby, Edward B. Overton, Lawrence P. Rozas

Faculty Publications

On 20 April 2010, the Deepwater Horizon explosion, which released a US governmentestimated 4.9 million barrels of crude oil into the Gulf of Mexico, was responsible for the death of 11 oil workers and, possibly, for an environmental disaster unparalleled in US history. For 87 consecutive days, the Macondo well continuously released crude oil into the Gulf of Mexico. Many kilometers of shoreline in the northern Gulf of Mexico were affected, including the fragile and ecologically important wetlands of Louisiana's Mississippi River Delta ecosystem. These wetlands are responsible for a third of the nation's fish production and, ironically, help to …

Concurrent Effects Of Resource Pulse Amount, Type, And Frequency On Community And Population Properties Of Consumers In Detritus-Based Systems, Donald A. Yee, Steven A. Juliano

Faculty Publications

Episodic resource inputs (i.e., pulses) can affect food web properties and community dynamics, but detailed mechanistic understanding of such effects remain elusive. Natural aquatic microsystems (e.g., tree holes, human-made containers) are colonized by invertebrates that form complex food webs dependent on episodic and sometimes sizeable inputs of allochthonous detritus from adjacent terrestrial environments. We investigated how variation in pulse frequency, amount, and resource type interacted to affect richness, abundance, composition, and population sizes of colonizing invertebrates in water-filled tires and tree hole analogs in a forest habitat. Different container types were used to assess the generality of effects across two …

Development Of A Protocol To Measure Gene Expression In The Mouse Tibia, Daniel Hoover

Biomedical Engineering

Numerous molecular factors active in bone tissue direct fracture repair and remodeling which can be altered by disease conditions such as Peripheral Arterial Disease (PAD) and Osteoporosis. Methods of molecular biology are commonly applied to investigate the expression and role of these molecular factors. This project presents a robust three-step protocol for examining gene expression in the mouse tibia. The protocol begins with isolating RNA from a flash frozen tibia sample. The isolated RNA is reverse transcribed into cDNA. Finally, PCR is performed to indentify expressed genes. Establishing this protocol will allow further research into the mechanisms of bone remodeling …

Costs And Benefits Of Jasmonic Acid Induced Responses In Soybean, A. K. Accamando, J. T. Cronin

Faculty Publications

In response to herbivory, plants have evolved defense strategies to reduce herbivore preference and performance. A strategy whereby defenses are induced only upon herbivory can mitigate costs of defense when herbivores are scarce. Although costs and benefits of induced responses are generally assumed, empirical evidence for many species is lacking. Soybean (Glycine max L. Merr.) has emerged as a model species with which to address questions about induced responses. To our knowledge, this is the first study to examine the fitness costs and benefits of jasmonic acid-induced responses by soybean in the absence and presence of soybean loopers (Chrysodeix includens …

Enhancing Content Knowledge Of In-Service Science Teachers Through Model And Modeling, Naheed Perveen, Sadia Muzzafar Bhutta

Institute for Educational Development, Karachi

The guiding question for this paper is; how does model and modeling enable student-teachers to develop a conceptual understanding of the cell as a structural and functional unit of living things? A teaching unit ‘The Cell’ was designed in view that models are a major teaching and learning tool for developing scientific thinking, whereas modeling means a process of forming representation. The teaching and learning strategies reported here encapsulated four modeling phases. Firstly, student-teachers modeled historical development of cell through a time line and role play and discussed the evolutionary and tentative nature of science. Secondly, the candy factory analogy …

A Prospective Observational Study Of Mycophenolate Mofetil Treatment In Progressive Diffuse Cutaneous Systemic Sclerosis Of Recent Onset., Fabian A. Mendoza, Md, Sarah J. Nagle, Jason B. Lee, Md, Sergio A. Jimenez

Jefferson Institute of Molecular Medicine Papers and Presentations

OBJECTIVE: A prospective observational study of mycophenolate mofetil (MMF) treatment in patients with diffuse progressive cutaneous systemic sclerosis (SSc) of recent onset.

METHODS: Twenty-five previously untreated consecutive patients with recent-onset (< 24 mo) diffuse progressive cutaneous SSc received MMF as the only disease-modifying therapy. Modified Rodnan skin score (mRSS) and affected body surface area (BSA) were compared from initiation of MMF to study end. Pulmonary function tests performed at the same institution before therapy and at study end were available in 15 patients. Histopathology and real-time PCR assessment of fibrosis-related gene expression were performed before and after treatment in skin biopsies from 3 patients.

RESULTS: At 18.2 ± 8.73 months of MMF therapy (median 2000 mg/day) the mRSS decreased from 24.56 ± 8.62 to 14.52 ± 10.9 (p = 0.0004) and the affected BSA from 36% ± 16% to 14% ± 13.3% (p = 0.00001). Pulmonary function tests remained stable from initiation of MMF to the end of the study. Skin histopathology showed a remarkable reduction in accumulation of fibrotic tissue. Real-time PCR …

Department of Radiology

Abstract

BACKGROUND:

In papillary and follicular thyroid cancers (PTC, FTC), nodal and distant metastasis are generally considered important determinants of recurrence and survival, respectively. However, there is no consensus about the threshold primarytumour size (PTS) for these determinants. The aim of this study was to assess size relationships for developing nodal, pulmonary, bone and overall distant metastases.

METHODS:

This prospective study covered 139 (93 females and 46 males) consecutive biopsy proven patients with PTC (114/139, mean age 41.0 ± 15.7 years, M: F, 35%:65%) and FTC (25/139, mean age 39.2 ± 14.3 years, M: F: 24%:76%).

(When) Does A Contract Claim Trump A Takings Claim? Lessons From The Water Wars, David W. Spohr

Washington Journal of Environmental Law & Policy

As in other river basins, the disparity in the Columbia is growing between ever-expanding water demands and ever-shrinking water availability. Looming near the forefront of decisions on how to manage such waters is the potential liability the government faces if it reduces water distributions to further environmental objectives. While recent cases raise fascinating takings and contract issues, the most interesting issue may be the intersection of the available remedies. Does the contractual relationship between an aggrieved water user and the government preclude a takings claim, even where the contract claim ultimately fails? On one end of the spectrum, courts have …

Jumpstarting The Stalled Gender Revolution: Justice Ginsburg And Reconstructive Feminism, Joan C. Williams

UC Law Journal

Justice Ruth Bader Ginsburg, since about 1980, has been painted as a feminist committed to “formal equality.” Recent work has contested this depiction. This Article uncovers additional evidence that Ginsburg’s goal was not mere formal equality; her goal was to deconstruct the breadwinner-homemaker system in which men and women were seen as belonging to separate spheres. Ginsburg saw this system as subordinating women, and in that sense is an antisubordination theorist. Yet lumping her together with Catharine MacKinnon, often seen as legal feminism’s foremost antisubordination theorist, proves confusing for a number of reasons. A chief difference is their attitudes towards …

The Law Of Gender Stereotyping And The Work-Family Conflicts Of Men, Stephanie Bornstein

UC Law Journal

This Article looks back to the early equal protection jurisprudence of the 1970s and Ruth Bader Ginsburg’s litigation strategy of using men as plaintiffs in sex discrimination cases to cast a renewed focus on antidiscrimination law as a means to redress the work-family conflicts of men. From the beginning of her litigation strategy as the head of the ACLU Women’s Rights Project, Ginsburg defined sex discrimination as the detrimental effects of gender stereotypes that constrained both men and women from living their lives as they wished—not solely the minority status of women. The same sex-based stereotypes that kept women out …

A Tale Of Three Families: Historical Households, Earned Belonging, And Natural Connections, Allison Anna Tait

UC Law Journal

Cases targeting family regulation in the 1970s turned, for the first time, on three contrasting and sometimes competing theories of the family: historical households, earned belonging, and natural connections. This Article introduces and defines these three theories and offers a descriptive account of how the theories were used by litigants and the Supreme Court alike to measure discrimination, evaluate the rights of individual family members, and, often, increase household equality. The theory of historical households, developed with great success by Ruth Bader Ginsburg, invoked a Blackstonian family defined by gender hierarchy and the law of coverture, and posited that this …

High-Amylose Resistant Starch Increases Hormones And Improves Structure And Function Of The Gastrointestinal Tract: A Microarray Study, Michael J. Keenan, Roy J. Martin, Anne M. Raggio, Kathleen L. Mccutcheon, Ian L. Brown, Anne Birkett, Susan S. Newman, Jihad Skaf, Maren Hegsted, Richard T. Tulley, Eric Blair, June Zhou

Faculty Publications

Background/Aims: Type 2 resistant starch from high-amylose maize (HAM-RS2) is associated with increased fermentation, increased expression of proglucagon (gene for GLP-1) and peptide YY (PYY) genes in the large intestine, and improved health. To determine what other genes are up- or downregulated with feeding of HAM-RS2, a microarray was performed. Methods: Adult, male Sprague Dawley rats were fed one of the following three diets for a 4-week study period: cornstarch control (CC, 3.74 kcal/g), dietary energy density control (EC, 3.27 kcal/g), and 30% HAM-RS2 (RS, 3.27 kcal/g). Rat microarray with ∼27,000 genes and validation of 94 representative genes with multiple …

The Kappa Opioid Agonist, Salvinorin A, Attenuates Locomotor Effects Of Morphine But Not Morphine-Induced Conditioned Place Preference, Stacy Dianne Engebretson

Masters Theses

Salvinorin A (SA), a selective kappa opioid receptor agonist, is the main psychoactive ingredient in the plant Salvia divinorum. The addiction potential of this naturally occurring hallucinogen is currently under investigation using well-validated preclinical screening procedures, including conditioned place preference (CPP). The primary aim of the current study was to determine the effects of SA on CPP established by morphine in adult rats. A secondary aim was to determine if the vehicle used to dissolve SA, dimethylsulfoxide (DMSO), influenced the outcome of SA place conditioning. Rats were randomly assigned to one of four treatment groups: morphine (10 mg/kg) vs. …

An Essay On The Ontology Of Reasons, Jeremy Anon Dickinson

Philosophy - Dissertations

I argue that many recent anti-psychologistic accounts of agential reasons are unsatisfactory. I also argue that psychologistic accounts are false. Then I develop and defend an anti-psychologistic, propositionalist theory of reasons whereby agential reasons are propositions. I also develop a corresponding anti-psychologistic account of reason-explanation that is able to help resolve some of the more difficult problems for theories of anti-psychologism. Next, I argue for a Russellian theory of propositionalism. Finally, I argue against teleological theories of reasons.

Involvement Of Microrna Families In Cancer, Stefan Wuchty, Dolores Arjona, Serdar Bozdag, Peter O. Bauer

Mathematics, Statistics and Computer Science Faculty Research and Publications

Collecting representative sets of cancer microRNAs (miRs) from the literature we show that their corresponding families are enriched in sets of highly interacting miR families. Targeting cancer genes on a statistically significant level, such cancer miR families strongly intervene with signaling pathways that harbor numerous cancer genes. Clustering miR family-specific profiles of pathway intervention, we found that different miR families share similar interaction patterns. Resembling corresponding patterns of cancer miRs families, such interaction patterns may indicate a miR family’s potential role in cancer. As we find that the number of targeted cancer genes is a naı¨ve proxy for a cancer …

An Evolutionary Search Paradigm That Learns With Past Experiences, Liang Feng, Yew-Soon Ong, Ivor Tsang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

A major drawback of evolutionary optimization approaches in the literature is the apparent lack of automated knowledge transfers and reuse across problems. Particularly, evolutionary optimization methods generally start a search from scratch or ground zero state, independent of how similar the given new problem of interest is to those optimized previously. In this paper, we present a study on the transfer of knowledge in the form of useful structured knowledge or latent patterns that are captured from previous experiences of problem-solving to enhance future evolutionary search. The essential contributions of our present study include the meme learning and meme selection …
