Global Farm Animal Production And Global Warming: Impacting And Mitigating Climate Change, Gowri Koneswaran, Danielle Nierenberg

Agribusiness Collection

BACKGROUND: The farm animal sector is the single largest anthropogenic user of land, contributing to many environmental problems, including global warming and climate change.

OBJECTIVES: The aim of this study was to synthesize and expand upon existing data on the contribution of farm animal production to climate change.

METHODS: We analyzed the scientific literature on farm animal production and documented greenhouse gas (GHG) emissions, as well as various mitigation strategies.

DISCUSSIONS: An analysis of meat, egg, and milk production encompasses not only the direct rearing and slaughtering of animals, but also grain and fertilizer production for animal feed, waste storage …

Systematic Reviews Of Animal Experiments Demonstrate Poor Contributions To Human Healthcare, Andrew Knight

Experimentation Collection

Widespread reliance on animal models during preclinical research and toxicity testing assumes their reasonable predictivity for human outcomes. However, of 20 published systematic reviews examining human clinical utility located during a comprehensive literature search, animal models demonstrated significant potential to contribute toward clinical interventions in only two cases, one of which was contentious. Included were experiments expected by ethics committees to lead to medical advances, highly-cited experiments published in major journals, and chimpanzee experiments—the species most generally predictive of human outcomes. Seven additional reviews failed to demonstrate utility in reliably predicting human toxicological outcomes such as carcinogenicity and teratogenicity. Results …

Honestly, Who Else Would Fund Such Research? Reflections Of A Non-Smoking Scholar, Michael L. Marlow

Economics

Many public-health researchers are quick to raise charges of bias to explain away the few studies that reach politically incorrect conclusions. Claims of bias are often thrown at researchers who are funded by the industries targeted for aggressive intervention. This paper discusses whether it makes sense that bias is a relevant issue only when researchers have connections to private industry or find fault with government intervention. I focus on the issue of whether smoking bans harm any restaurant or bar owners. This area of research has experienced a large number of claims of bias and deception, leveled against research that …

Bull Nutrition, Julie Walker, George Perry, Ken Olsen

SDSU Extension Extra Archives

Bull nutrition is often overlooked by many producers, except when problems arise. Bulls are often managed as one group even though there may be large differences in age, size, and body condition. Seedstock producers are the primary individuals managing the development program of bulls being sold. For commercial producers, feeding programs usually include feeding purchased bull(s) from delivery until the breeding season and bulls retained from one breeding season to the next. The debate over the correct method for developing bulls is not settled: Should you develop bulls at a moderate rate of gain? Or should you develop bulls on …

Heritability Of Longevity In Captive Populations Of Nondomesticated Mammals And Birds, Robert Ricklefs, Carlos Cadena

Biology Department Faculty Works

We used variance components analysis and offspring–parent regression to estimate the heritability of age at death in zoo populations of several species of mammals and birds. A meta-analysis over 14 species of mammals indicated a variance–component heritability of 0.53. More conservative regression estimates of heritability for the same species averaged 0.17. Offspring–parent regressions were not significant for any of eight species of birds. Heritabilities for data simulated with frailty and age-at-death models showed that sources of variation in age at death cannot be distinguished from observed heritabilities. The CVA in age at death in six mammal species, based on parent–offspring …

Greenpeace, Earth First! And The Earth Liberation Front: The Progression Of The Radical Environmental Movement In America, Christopher J. Covill

Senior Honors Projects

Causes of worldwide environmental destruction created a form of activism, Ecotage with an incredible success rate. Ecotage uses direct action, or monkey wrenching, to prevent environmental destruction. Mainstream conservation efforts were viewed by many environmentalists as having failed from compromise inspiring the birth of radicalized groups. This eventually transformed conservationists into radicalists. Green Peace inspired radical environmentalism by civil disobedience, media campaigns and direct action tactics, but remained mainstream. Earth First’s! philosophy is based on a no compromise approach. They took direct action tactics further than Green Peace was willing too. Earth First’s! direct action campaigns epitomize modern environmental radicalism. …

Collagen 11a1 Is Indirectly Activated By Lymphocyte Enhancer-Binding Factor 1 (Lef1) And Negatively Regulates Osteoblast Maturation, Rachel A. Kahler, Sorcha M.C. Yingst, Luke H. Hoeppner, Eric D. Jensen, David Krawczak, Julia T. Oxford, Jennifer J. Westendorf

Biomedical Research Institute Publications and Presentations

Alpha 1 (XI) collagen (Col11a1) is essential for normal skeletal development. Mutations in Col11a1 cause Marshall and Stickler syndromes, characterized by craniofacial abnormalities, nearsightedness and hearing abnormalities. Despite its link to human diseases, few studies have characterized the factors that control Col11a1 transcription. We previously identified Col11a1 as a differentially expressed gene in Lef1-suppressed MC3T3 preosteoblasts. Here we report that Lef1 activates the Col11a1 promoter. This activation is dependent upon the DNA binding domain of Lef1, but does not require the ß-catenin interaction domain, suggesting that it is not responsive to Wnt signals. Targeted deletion of Col11a1 with an antisense …

Effects Of Music On Emotional And Physiological Responses, Jenifer Fritz

Undergraduate Psychology Research Methods Journal

Past research has suggested that music with fast tempos and rhythms have different physiological and emotional effects than music with slow tempos and rhythms. If these beliefs and studies are accurate, an individual will have physiological changes and report different emotions and moods after listening to music, and these changes will depend on the style of music that was heard. Twenty-nine participants were asked to report current emotions, moods, and musical preferences before and after listening to one of four musical selections: rock, rap, classical, and no music. Emotion and mood state were not affected by any of the musical …

Small Mammal Diversity And Population Densities In Monteverde, Costa Rica: A Follow- Up Study Of Rothman (1999), May 2008, Caroline C. Burdick

Monteverde Institute: Tropical Ecology and Conservation

Widespread deforestation and El Niño events may have an effect on Costa Rican’s climate, and overall, Monteverde’s climate is becoming drier and less predictable due to short-term global warming impacts. Due to widespread habitat fragmentation and hunting, the population of small and medium-sized mammals has decreased dramatically. This study investigates rodent species richness, abundance, and diversity in three life zones in Monteverde, Costa Rica, to determine whether they have changed since a similar study conducted in 1999. Small mammals were sampled in Tropical Lower Montane Wet Forest, Tropical Premontane Moist Forest, and Tropical Lower Montane Rain Forest in the Monteverde …

Coregulation Of A Neighboring Est With Rhogap, Tia Hughes

Masters Theses & Specialist Projects

It has been reported that the crossveinless-c locus of Drosophila melanogaster corresponds the RhoGAP88C gene. This determination was based on three criteria: proximity in genetic map position, complementation tests, and similarity of phenotype between RhoGAP88C RNAi constructs and the phenotype of hypomorphic cv-c' mutant homozygotes, both of which eliminate posterior crossveins (Denholm et al. 2005). There are several genes that map to this region of chromosome 3, including both RhoGAP88C, and a poorly annotated PDZ-domain containing gene corresponding to Expressed Sequence Tag (EST) Clot 13975 (approximately 60 kb upstream from the RhoGAP88C transcriptional start). A P-element insertion P[PZ]l(3)06951 is located …

Love And Low Serotonin, Leslie Parrish

Masters Theses & Specialist Projects

The following is a novella that depicts a young man and woman in search of differing goals, but the essence of their goals does have something in common: each of their pursuits, if obtained, allows for self-control and recovered lifestyle. However, their lives are far from average throughout the story. Themes such as bulimia, drug use, loveless sex, voyeurism, lucid dreaming and emergency room healthcare are explored in the form of fiction. Both of the main characters in this story explore their world with a measure of obsession, and like any worthy character, their obsessions transform into decisions and actions …

The Effectiveness Of A "None Of The Above" Answer Option In Multiple Choice Grammar Tests, Andrea Sides

Masters Theses & Specialist Projects

This study examines the use of "none of the above" (NOTA) as an answer option in a multiple-choice grammar test. Results from previous research on this topic have been mixed. Two forms of a grammar test, one without a NOTA option and one with a NOTA option, were developed and administered to a sample of 160 undergraduate students. Differences between the forms in item difficulty and discrimination were examined. Analysis revealed no differences in item discrimination or item difficulty between items without a NOTA option and items with a NOTA option. A discussion of the results, limitations, and suggestions for …

Pcr-Ddge Comparison Of Fecal Bacteria From Captive And Wild Populations Of The Endangered San Esteban Island Chuckwalla (Sauromalus Varius), Tina Kelley

Masters Theses & Specialist Projects

Most modern reptiles are carnivorous or insectivorous, whereas less than 2% of the >7,800 currently recognized species are considered to be herbivorous. Of these, herbivory is confined entirely to lizards; less than 3% of known lizard species eat significant amounts of plants. Most, if not all, herbivorous animals utilize a population of symbiotic microorganisms which can break down plant structural polymers. This study analyzes the bacterial populations from fecal/uric acid deposits of wild and captive samples of the endangered, herbivorous San Esteban chuckwalla (Sauromalus varius: Iguanidae). Substrate and diet samples were also analyzed. Most studies of digestive symbionts use indirect …

Quality Assurance Of Radiation Therapy Planning Systems: Current Status And Remaining Challenges., Jacob Van Dyk

Oncology Publications

Computerized radiation therapy planning systems (RTPSs) are pivotal for treatment planning. The acceptance, commissioning, and quality control of RTPSs are uniquely complex and are described in the American Association of Physicists in Medicine Task Group Report 53 (1998) and International Atomic Energy Agency Technical Report Series No. 430 (2004). The International Atomic Energy Agency also developed a document and data package for use by vendors and purchasers to aid with acceptance testing of RTPSs. This document is based on International Electrotechnical Commission standard 62083 (2000) and describes both "type" tests to be performed in the factory and "site" tests to …

An Integrodifferential Equation Modeling 1-D Swarming Behavior, Andrew Leverentz

HMC Senior Theses

We explore the behavior of an integrodifferential equation used to model one-dimensional biological swarms. In this model, we assume the motion of the swarm is determined by pairwise interactions, which in a continuous setting corresponds to a convolution of the swarm density with a pairwise interaction kernel. For a large class of interaction kernels, we derive conditions that lead to solutions which spread, blow up, or reach a steady state. For a smaller class of interaction kernels, we are able to make more quantitative predictions. In the spreading case, we predict the approximate shape and scaling of a similarity profile, …

Statewide Feral Hog Abatement Pilot Project, 2006-2007, Billy Higginbotham, Greg Clary, Larry Hysmith, Michael J. Bodenchuk

National Conference on Feral Hogs (2008)

The two year Feral Hog Abatement Project was implemented in January 2006. On-site technical assistance (direct control) was provided to landowners at three pilot sites (Post Oak Savannah/Pineywoods, Blacklands Prairie and Coastal Prairie) while group educational events (indirect control) emphasizing adoption of efficient landowner-initiated control methods were conducted statewide. Both groups of clientele participating in the project and were surveyed to measure the overall economic impact of this Texas Department of Agriculture-funded initiative. Data spanned the period 2005-2007 so as to estimate the economic impact of technical assistance and educational programs to the agricultural community.
Wildlife Service technicians worked with …

Reliability Of Peak Cardiorespiratory Responses During Aquatic Treadmill Exercise, William M. Silvers, Dennis G. Dolny

International Journal of Aquatic Research and Education

Twenty-four college-age participants took part in 2 protocols on an aquatic treadmill (ATM) submerged to the xiphoid process. ATM speed was increased to 212.2 + 19.2 m/min, and water-jet resistance was increased 10% every minute thereafter. Rest between sessions was at least 6 days. Oxygen consumption (VO2), heart rate (HR), minute ventilation (VE), tidal volume (VT), breathing frequency (f), and respiratory exchange ratio (RER) were measured continuously. Rating of Perceived Exertion (RPE) was recorded immediately after each test, and blood lactate (LA) was measured 3 min after. There were no significant differences for Trial 1 vs. Trial 2 for any …
