PCOM Scholarly Works

We are researchers and clinicians working on Alzheimer's disease (AD) or related topics, and we write to express our concern that one particular aspect of the disease has been neglected, even though treatment based on it might slow or arrest AD progression. We refer to the many studies, mainly on humans, implicating specific microbes in the elderly brain, notably herpes simplex virus type 1 (HSV1), Chlamydia pneumoniae, and several types of spirochaete, in the etiology of AD. Fungal infection of AD brain has also been described, as well as abnormal microbiota in AD patient blood. The first observations of HSV1 …

Remote Sensing Derived Fire Frequency, Soil Moisture And Ecosystem Productivity Explain Regional Movements In Emu Over Australia, Nima Madani, John S. Kimball, Mona Nazeri, Lalit Kumar, David L.R. Affleck

Numerical Terradynamic Simulation Group Publications

Species distribution modeling has been widely used in studying habitat relationships and for conservation purposes. However, neglecting ecological knowledge about species, e.g. their seasonal movements, and ignoring the proper environmental factors that can explain key elements for species survival (shelter, food and water) increase model uncertainty. This study exemplifies how these ecological gaps in species distribution modeling can be addressed by modeling the distribution of the emu (Dromaius novaehollandiae) in Australia. Emus cover a large area during the austral winter. However, their habitat shrinks during the summer months. We show evidence of emu summer habitat shrinkage due to …

Environmental Controls On The Increasing Gpp Of Terrestrial Vegetation Across Northern Eurasia, P. Dass, Michael A. Rawlins, John S. Kimball, Y. Kim

Numerical Terradynamic Simulation Group Publications

Terrestrial ecosystems of northern Eurasia are demonstrating an increasing gross primary productivity (GPP), yet few studies have provided definitive attribution for the changes. While prior studies point to increasing temperatures as the principle environmental control, influences from moisture and other factors are less clear. We assess how changes in temperature, precipitation, cloudiness, and forest fires individually contribute to changes in GPP derived from satellite data across northern Eurasia using a light-use- efficiency-based model, for the period 1982–2010. We find that annual satellite-derived GPP is most sensitive to the temperature, precipitation and cloudiness of summer, which is the peak of the …

Monitoring Yogurt Culture Fermentation And Predicting Fermentation Endpoint With Fluorescence Spectroscopy, Timothey P. Mains, Frederick Alan Payne, Michael P. Sama

Biosystems and Agricultural Engineering Faculty Publications

Determination of the endpoint of yogurt culture fermentation is a process parameter that could benefit from automation. The feasibility of using a fluorescence sensor technology based on 280 nm excitation and 350 nm emission to predict the endpoint of yogurt culture fermentation was investigated and compared with the endpoint prediction from a near-infrared (880 nm) light backscatter sensor. Yogurt cultures with three levels of milk solids (8%, 10%, and 12%) and three temperatures (40°C, 43°C, and 46°C) were tested with three replications in a 3 x 3 factorial design (n = 27). Prediction models were developed for each optical measurement …

From Obedience To Contagion: Discourses Of Power In Milgram, Zimbardo, And The Facebook Experiment, Timothy Recuber

Sociology: Faculty Publications

When the public outcry concerning the ‘Facebook experiment’ began, many commentators drew parallels to controversial social science experiments from a prior era. The infamous Milgram (1963) and Zimbardo (1973) experiments concerning the social psychology of obedience and aggression seemed in some ways obvious analogs to the Facebook experiment, at least inasmuch as all three violated norms about the treatment of human subjects in research. But besides that, what do they really have in common? In fact, a close reading of Milgram, Zimbardo, and the Facebook experiment reveals something about the way power—both as a subject of scholarly inquiry and as …

Unequal Edge Inclusion Probabilities In Link-Tracing Network Sampling With Implications For Respondent-Driven Sampling, Miles Q. Ott, Krista J. Gile

Statistical and Data Sciences: Faculty Publications

Respondent-Driven Sampling (RDS) is a widely adopted linktracing sampling design used to draw valid statistical inference from samples of populations for which there is no available sampling frame. RDS estimators rely upon the assumption that each edge (representing a relationship between two individuals) in the underlying network has an equal probability of being sampled. We show that this assumption is violated in even the simplest cases, and that RDS estimators are sensitive to the violation of this assumption.

A Multistep Approach To Single Nucleotide Polymorphism-Set Analysis: An Evaluation Of Power And Type I Error Of Gene-Based Tests Of Association After Pathway-Based Association Tests, Alessandra Valcarcel, Kelsey Grinde, Kaitlyn Cook, Alden Green, Nathan Tintle

Statistical and Data Sciences: Faculty Publications

The aggregation of functionally associated variants given a priori biological information can aid in the discovery of rare variants associated with complex diseases. Many methods exist that aggregate rare variants into a set and compute a single p value summarizing association between the set of rare variants and a phenotype of interest. These methods are often called gene-based, rare variant tests of association because the variants in the set are often all contained within the same gene. A reasonable extension of these approaches involves aggregating variants across an even larger set of variants (eg, all variants contained in genes within …

Government As Owner Of Intellectual Property? Considerations For Public Welfare In The Era Of Big Data, Ruth L. Okediji

Vanderbilt Journal of Entertainment & Technology Law

Open government data policies have become a significant part of innovation strategies in many countries, allowing access, use and re-use of government data to improve government transparency, foster civic engagement, and expand opportunities for the creation of new products and services. Rarely, however, do open data policies address intellectual property rights that may arise from free access to government data. Ownership of knowledge goods created from big data is governed by the default rules of intellectual property laws which typically vest ownership in the creator/inventor. By allowing, and in some cases actively encouraging, private capture of the downstream goods created …

Classroom Context And The Relations Between Social Withdrawal And Peer Victimization, Ellyn Bass, Jonathan Santo, Josafa M. Da Cunha, Cara Neufeld

Psychology Faculty Publications

This study examined the relationship between social withdrawal (isolation and unsociability) and peer victimization by exploring the moderating influences of gender, classroom norms of social withdrawal, individualism, and collectivism. One hundred fifty-eight adolescents (Mage 5 14.11, SD 5 1.10; 46.3% boys) in 7th and 8th grade from Curitiba, Brazil, completed peer assessments of isolation, unsociability, peer victimization, and self-reports of classroom individualism and collectivism. Isolation and unsociability were aggregated into classroom norms. Data were analyzed using multilevel modeling. Isolation and unsociability positively predicted victimization. Unsociability was a positive predictor of victimization in low-unsociability classrooms. Isolation was negatively associated with victimization …

Hybrid Diesel-Electric Drivetrain For Small Agricultural Field Machines, Joseph Jackson, Joseph S. Dvorak

Biosystems and Agricultural Engineering Faculty Publications

In this project, a series electric drivetrain sized for small agricultural machinery was developed and tested. Electric drives have noted benefits in simplicity, controllability, integration with other electronics such as those that provide autonomous action, and in efficiency over a wide operating range. Their biggest drawback for agricultural use is the limited capacity of electrical energy storage. A series hybrid drivetrain provides a method to overcome these capacity constraints through the use of chemical energy storage. The series hybrid drivetrain in this research was designed using well-established components. It consisted of a diesel-electric generator, a lead acid battery pack, a …

Using Wii Technology And Experiential Learning To Teach Newtonian Mechanics To Rural Middle School Students, Joseph S. Dvorak, Tanya C. Franke-Dvorak, Shane Neel

Biosystems and Agricultural Engineering Faculty Publications

This study looked at the effects of an experiential learning activity using the accelerometer in the Wii Remote to teach basic concepts of Newtonian mechanics, e.g., acceleration, to middle school students in a rural school district. A major prerequisite for students at the mid-level in biosystems engineering programs is that they have a good knowledge of basic science, including physics. Education in these concepts must begin before college, such as at the middle school level. Improvements in science education are vitally necessary to achieve essential learning outcomes for middle school students in the U.S. and to prepare these students for …

Effects Of Chemical Amendments To Swine Manure On Runoff Quality, Elizabeth L. Bullock, Dwayne R. Edwards, Phillip A. Moore Jr., Richard S. Gates

Biosystems and Agricultural Engineering Faculty Publications

Land-applied swine manure can be an environmental concern when runoff losses of manure constituents occur. The use of chemical amendments to mitigate these losses has been investigated for poultry litter, but materials such as swine manure have received less attention in this context, particularly at the plot scale or larger. The objective of this experiment was to evaluate the impacts of aluminum sulfate (alum; Al₂(SO₄)₃), aluminum chloride (AlCl₃), and ferric chloride (FeCl₃) addition on runoff of selected constituents of land-applied swine manure. Manure was collected from feeder pigs fed a …

Methods For Calculating Relative Cross-Track Error For Asabe/Iso Standard 12188-2 From Discrete Measurements, Joseph D. Rounsaville, Joseph S. Dvorak, Timothy S. Stombaugh

Biosystems and Agricultural Engineering Faculty Publications

ASABE/ISO Standard 12188-2 provides test procedures for positioning and guidance systems in agricultural vehicles during straight and level travel. While the standard provides excellent descriptions of test procedures, it does not provide detail on methods to carry out the calculations necessary to calculate relative cross-track error (XTE), which is the primary error statistic used to judge accuracy. Given the travel speed and sampling constraints provided by the standard, the difference between a method based on nearest points or one based on path interpolation could hypothetically be as large as 25 cm. In this project, the standard was used to estimate …

A Comprehensive Benchmarking Study Of Protocols And Sequencing Platforms For 16s Rrna Community Profiling, Rosalinda D’Amore, Umer Zeeshan Ijaz, Melanie Schirmer, John G. Kenny, Richard Gregory, Alistair C. Darby, Migun Shakya

Dartmouth Scholarship

In the last 5 years, the rapid pace of innovations and improvements in sequencing technologies has completely changed the landscape of metagenomic and metagenetic experiments. Therefore, it is critical to benchmark the various methodologies for interrogating the composition of microbial communities, so that we can assess their strengths and limitations. The most common phylogenetic marker for microbial community diversity studies is the 16S ribosomal RNA gene and in the last 10 years the field has moved from sequencing a small number of amplicons and samples to more complex studies where thousands of samples and multiple different gene regions are interrogated. …

Identification Of Compounds Of Allelopathic Extracts From Two Species Of Metapeyssonnelia (Rhodophyta) Growing On The Hydrocoral, Millepora Complanata, In Puerto Rico, Maria I. Reyes-Contreras, Aniuska Kazandjian, David L. Ballantine

Gulf and Caribbean Research

Two Puerto Rican species of the encrusting red alga Metapeyssonnelia are known to overgrow and kill the hydrocoral Millepora complanata. The overgrowth is accompanied by bleaching or tissue lightening regions surrounding the growing margin of the algae on the coral tissue. Lipophilic and hydrophilic extracts from Metapeyssonnelia corallepida and M. milleporoides were obtained and analyzed by GC-MS. The following compounds were identified from M. corallepida: squalene and 5-(hydroxymethyl)-2-(dimethoxymethyl)-furan3-methoxycarbonyl-1,1-diethyl-2-buten-4-olide and from M. milleporoides: 2,4-dit-butyl phenol, 2(3H)-furanone and dihydro-4,4-dimethyl-(CAS), terpenes, furanones and phenol. Aliquots of crude extracts of both Metapeyssonnelia species applied to coral fragments resulted in visible changes …

Diets Of Atlantic Sharpnose Shark (Rhizoprionodon Terraenovae) And Bonnethead (Sphyrna Tiburo) In The Northern Gulf Of Mexico, Tyler Harrington, Jeff Plumlee, J. Marcus Drymon, David Wells

Gulf and Caribbean Research

Diets of two coastal sharks, Atlantic Sharpnose Shark (Rhizoprionodon terraenovae) and Bonnethead (Sphyrna tiburo), were examined along the Texas and Alabama coasts in the northern Gulf of Mexico (GOM). Atlantic Sharpnose Sharks were collected from the northwest (n= 209) and northcentral (n= 245) GOM regions while Bonnetheads were collected from two locations within the northwest GOM (Galveston, Texas, n= 164; Matagorda, Texas, n= 79). Dietary analysis was conducted using stomach contents identified to the lowest taxonomic level, which were quantified using the index of relative importance (IRI) and non-parametric statistical analyses. Atlantic Sharpnose Sharks were revealed to …

Maternal Allostatic Load During Pregnancy: Predicting Length Of Gestation, Molly Malany Sayre

Sociology, Anthropology, and Social Work Faculty Publications

Allostatic load, or the “wear and tear” on the body due to stress, is thought to have a negative impact on length of pregnancy and contribute to health disparities in preterm birth. However, the magnitude of the effect on birth outcomes is unknown, in part due to questions of timing of measurement of allostatic load during pregnancy. This study used linear regression analysis of data from 156 pregnant women to test whether allostatic load is a predictor of length of gestation in the study sample, finding that third trimester allostatic load predicted length of gestation among women with full-term births. …

Adolescent Methylphenidate Treatment Differentially Alters Adult Impulsivity And Hyperactivity In The Spontaneously Hypertensive Rat Model Of Adhd, Sucharita S. Somkuwar, Kathleen M. Kantak, Michael T. Bardo, Linda P. Dwoskin

Psychology Faculty Publications

Impulsivity and hyperactivity are two facets of attention deficit/hyperactivity disorder (ADHD). Impulsivity is expressed as reduced response inhibition capacity, an executive control mechanism that prevents premature execution of an intermittently reinforced behavior. During methylphenidate treatment, impulsivity and hyperactivity are decreased in adolescents with ADHD, but there is little information concerning levels of impulsivity and hyperactivity in adulthood after adolescent methylphenidate treatment is discontinued. The current study evaluated impulsivity, hyperactivity as well as cocaine sensitization during adulthood after adolescent methylphenidate treatment was discontinued in the Spontaneously Hypertensive Rat (SHR) model of ADHD. Treatments consisted of oral methylphenidate (1.5 mg/kg) or water …

Critical Needs In Drug Discovery For Cessation Of Alcohol And Nicotine Polysubstance Abuse, C. E. Van Skike, Sarah E. Maggio, A. R. Reynolds, E. M. Casey, Michael T. Bardo, Linda P. Dwoskin, M. A. Prendergast, Kimberly Nixon

Psychology Faculty Publications

Polysubstance abuse of alcohol and nicotine has been overlooked in our understanding of the neurobiology of addiction and especially in the development of novel therapeutics for its treatment. Estimates show that as many as 92% of people with alcohol use disorders also smoke tobacco. The health risks associated with both excessive alcohol consumption and tobacco smoking create an urgent biomedical need for the discovery of effective cessation treatments, as opposed to current approaches that attempt to independently treat each abused agent. The lack of treatment approaches for alcohol and nicotine abuse/dependence mirrors a similar lack of research in the neurobiology …

Effect Of Vitamins C And E On Endothelial Function In Type 1 Diabetes Mellitus, Rachel-Marie Cazeau, Hong Huang, John A. Bauer, Robert P. Hoffman

Exploration And Implementation Of Innovative Efficiencies/Devices In Beet Processing For Energy Production, Patrick Mcinerney

Theses

The imminent depletion of fossil fuels, as well as concerns for energy security and the obligation to respond to climate change has led to expanding worldwide popularity of Anaerobic Digestion (AD) of energy crops. Sugar beet is a popular AD feedstock due to its favourable characteristics; however it can be quite labour intensive requiring a range of specialist equipment to process the crop prior to undergoing AD. A crucial stage of this process involves the size reduction of beet by a mechanical chopper unit; this pretreatment breaks open the cellulose structure of the crop and increases the surface area available …
