Natural Variation In Gestational Cortisol Is Associated With Patterns Of Growth In Marmoset Monkeys (Callithrix Geoffroyi), Aaryn C. Mustoe, Andrew K. Birnie, Andrew V. Korgan, Jonathan Bruce Santo, Jeffrey French

Psychology Faculty Publications

High levels of prenatal cortisol have been previously reported to retard fetal growth. Although cortisol plays a pivotal role in prenatal maturation, heightened exposure to cortisol can result in lower body weights at birth, which have been shown to be associated with adult diseases like hypertension and cardiovascular disease. This study examines the relationship between natural variation in gestational cortisol and fetal and postnatal growth in marmoset monkeys. Urinary samples obtained during the mother’s gestation were analyzed for cortisol. Marmoset body mass index (BMI) was measured from birth through 540 days in 30- or 60-day intervals. Multi-level modeling was used …

Satellite Evidence For A Large Source Of Formic Acid From Boreal And Tropical Forests, T Stavrakou, J F. Muller, J Peeters, A Razavi, L Clarisse, C Clerbaux, P Coheur, D Hurtmans, M De Maziere, C Vigouroux, Nicholas Deutscher, David Griffith, Nicholas Jones, Clare Paton-Walsh

Faculty of Science - Papers (Archive)

Formic acid contributes significantly to acid rain in remote environments1, 2. Direct sources of formic acid include human activities, biomass burning and plant leaves. Aside from these direct sources, sunlight-induced oxidation of non-methane hydrocarbons (largely of biogenic origin) is probably the largest source3, 4. However, model simulations substantially underpredict atmospheric formic acid levels5, 6, 7, indicating that not all sources have been included in the models. Here, we use satellite measurements of formic acid concentrations to constrain model simulations of the global formic acid budget. According to our simulations, 100–120 Tg of formic acid is produced annually, which is two …

Animal Pain: What It Is And Why It Matters, Bernard E. Rollin

Animal Welfare Collection

The basis of having a direct moral obligation to an entity is that what we do to that entity matters to it. The ability to experience pain is a sufficient condition for a being to be morally considerable. But the ability to feel pain is not a necessary condition for moral considerability. Organisms could have possibly evolved so as to be motivated to flee danger or injury or to eat or drink not by pain, but by ‘‘pangs of pleasure’’ that increase as one fills the relevant need or escapes the harm. In such a world, ‘‘mattering’’ would be positive, …

A Non-Invasive Assay For Monitoring Stress Responses: A Comparison Between Wild And Captive-Reared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Sinan Ali, Culum Brown

Aquaculture Collection

The stress response of wild and captive reared rainbowfish (Melanoteania duboulayi) following chasing by a simulated predator was examined. Cortisol release rate was monitored using a flow through system by measuring water borne hormone levels. Tests using known cortisol concentrations revealed that the technique yielded 95% of the cortisol present in the water. Cortisol release rates increased several fold in both populations after being chased but peaked at different time periods. Wild fish showed a typical stress response with release rate rising to (2.29±0.22 ng g⁻¹ h⁻¹) 2 h after exposure followed by rapid recovery. The captive-reared …

Diversification Or Cotton Recovery In The Malian Cotton Zone: Effects On Households And Women, Jeanne Yekeleya Coulibaly

INTSORMIL Scientific Publications

This dissertation investigates income diversification alternatives from the cotton economy and compares those initiatives with present policy measures to restore the cotton sector in Mali. It also derives the welfare implications for women of these various policy measures.

During the decade preceding 2011, farmers’ incomes in the cotton zone of Mali have been significantly affected by the downturn of the cotton economy explained by many factors including the low farm gate cotton price, the declining cotton yields and soil fertility concerns. In 2011, the Malian government substantially increased the farm gate cotton price as a result of the world cotton …

A Population-Genetic Perspective On The Similarities And Differences Among Worldwide Human Populations, Noah A. Rosenberg

Human Biology Open Access Pre-Prints

Recent studies have produced a variety of advances in the investigation of genetic similarities and differences among human populations. Here, I pose a series of questions about human population- genetic similarities and differences, and I then answer these questions by numerical computation with a single shared population-genetic dataset. The collection of answers obtained provides an introductory perspective for understanding key results on the features of worldwide human genetic variation.

Integration Versus Apartheid In Post-Roman Britain: A Response To Thomas Et Al. (2008), John E. Pattison

Human Biology Open Access Pre-Prints

The genetic surveys of the population of Britain conducted by Weale et al. and Capelli et al. produced estimates of the Germani immigration into Britain during the early Anglo-Saxon period, c.430-c.730. These estimates are considerably higher than the estimates of archaeologists. A possible explanation suggested that an apartheid-like social system existed in the early Anglo-Saxon kingdoms resulting in the Germani breeding more quickly than the Britons. Thomas et al. attempted to model this suggestion and showed that it was a possible explanation if all Anglo-Saxon kingdoms had such a system for up to 400 yrs. I noted that their explanation …

Computing Inconsistency Measure Based On Paraconsistent Semantics, Pascal Hitzler, Yue Ma, Guilin Qi

Computer Science and Engineering Faculty Publications

Measuring inconsistency in knowledge bases has been recognized as an important problem in several research areas. Many methods have been proposed to solve this problem and a main class of them is based on some kind of paraconsistent semantics. However, existing methods suffer from two limitations: (i) they are mostly restricted to propositional knowledge bases; (ii) very few of them discuss computational aspects of computing inconsistency measures. In this article, we try to solve these two limitations by exploring algorithms for computing an inconsistency measure of first-order knowledge bases. After introducing a four-valued semantics for first-order logic, we define an …

The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante

Psychology Faculty Publications

The electrophysiological correlates of recognition memory retrieval were examined in order to identify the neural conditions that precede accurate memory retrieval, characterize the processes that contribute to high and low confidence memory responses, and determine which memory processes are impaired after brain injury. Human electroencephalogram (EEG) was recorded during recognition confidence and source memory judgments in three experiments. In Experiment 1, mid-frontal pre-stimulus theta oscillations were found to precede the stimulus presentation of items that were successfully recollected, but they were not found to be predictive of item familiarity. Moreover, during stimulus presentation, recollection was associated with an increase in …

Lessons From Chimpanzee-Based Research On Human Disease: The Implications Of Genetic Differences, Jarrod Bailey

Laboratory Experiments Collection

Assertions that the use of chimpanzees to investigate human diseases is valid scientifically are frequently based on a reported 98–99% genetic similarity between the species. Critical analyses of the relevance of chimpanzee studies to human biology, however, indicate that this genetic similarity does not result in sufficient physiological similarity for the chimpanzee to constitute a good model for research, and furthermore, that chimpanzee data do not translate well to progress in clinical practice for humans. Leading examples include the minimal citations of chimpanzee research that is relevant to human medicine, the highly different pathology of HIV/AIDS and hepatitis C virus …

Empathy-Based Conservation: An Interdisciplinary Approach To Conservation Policy And Decision-Making, Kaitlyn Delashmutt

Department of Environmental Studies: Undergraduate Student Theses

In the late 20^th century, neuroscientists in Italy discovered a neuron in the brain capable of mentally mimicking the emotions derived from the actions of others (Rizzolatti and Craighero, 2004). It is the process that makes your elbow ache when someone else knocks their elbow on the counter or the uncontrollable smile that creeps up when someone smiles at you. No questions asked, people intuitively sense what others are feeling. The old school of thought was that humans deduced through logic and reason the actions of others and interpreted the emotions through a rational process (Carew et al, 2008). …

Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis estimates total factor productivity (TFP) growth in the agricultural sector of fourteen regions in Central America and the Caribbean. First, TFP is measured parametrically and non-parametrically, using the Ordinary Least Square (OLS) method and the Maximum Likelihood (ML) method to estimate a translog production function and the Malmquist index approach. Secondly, the thesis incorporates an environmental bad, CO₂ emissions from expansion of agricultural land by sacrificing forest area and estimates environmentally adjusted productivity (EAP) growth rates using an output distance function in order to assess how the growth of TFP rates changes when such a bad is …

Learned Recognition And Avoidance Of Invasive Mosquitofish By The Shrimp, Paratya Australiensis, Joshua D. Bool, Kristen Whitcomb, Erin Kydd, Culum Brown

Sentience Collection

Little is known about the learning ability of crustaceans, especially with respect to their anti-predator responses to invasive species. In many vertebrates, anti-predator behaviour is influenced by experience during ontogeny. Here, predator-naïve glass shrimp (Paratya australiensisis) were exposed to a predatory, invasive fish species, Gambusia holbrooki, to determine whether shrimp could learn to: (1) avoid the scent of Gambusia via classical conditioning; and (2) restrict their activity patterns to the night to reduce predatory encounters. Conditioned shrimp were placed in containers in aquaria containing Gambusia for 3 days during which time they could be harassed but not consumed by Gambusia. …

The Impact Of Category Separation On Unsupervised Categorization, Shawn W. Ell, Gregoryh F. Ashby

Psychology Faculty Scholarship

Most previous research on unsupervised categorization has used unconstrained tasks in which no instructions are provided about the underlying category structure or the stimuli are not clustered into categories. Few studies have investigated constrained tasks in which the goal is to learn pre-defined stimulus clusters in the absence of feedback. These studies have generally reported good performance when the stimulus clusters could be separated by a one-dimensional rule. The present study investigated the limits of this ability. Results suggest that even when two stimulus clusters are as widely separated as in previous studies, performance is poor if within-category variance on …

Four Types Of Activities That Affect Animals: Implications For Animal Welfare Science And Animal Ethics Philosophy, D. Fraser, A. M. Macrae

Ethnozoology and Animal Welfare Collection

People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology testing; (3) people cause direct but unintended harm to animals through crop production, transportation, night-time lighting, and many other human activities; and (4) people harm animals indirectly by disturbing ecological systems and the processes of nature, for example by destroying habitat, introducing foreign species, and causing pollution and climate change. Each type of activity affects vast numbers …

Molecular Systematics Of The Middle American Genus Hypopachus (Anura: Microhylidae), Eli Greenbaum, Eric N. Smith, Rafael O. De Sá

Biology Faculty Publications

We present the first phylogenetic study on the widespread Middle American microhylid frog genus Hypopachus. Partial sequences of mitochondrial (12S and 16S ribosomal RNA) and nuclear (rhodopsin) genes (1275 bp total) were analyzed from 43 samples of Hypopachus, three currently recognized species of Gastrophryne, and seven arthroleptid, brevicipitid and microhylid outgroup taxa. Maximum parsimony (PAUP), maximum likelihood (RAxML) and Bayesian inference (MrBayes) optimality criteria were used for phylogenetic analyses, and BEAST was used to estimate divergence dates of major clades. Population-level analyses were conducted with the programs NETWORK and Arlequin. Results confirm the placement of Hypopachus …

A History Of Low Back Pain Associates With Altered Electromyographic Activation Patterns In Response To Perturbations Of Standing Balance, Jesse V. Jacobs, Sharon M. Henry, Stephanie L. Jones, Juvena R. Hitt, Janice Y. Bunn

Exercise and Sport Studies: Faculty Publications

People with a history of low back pain (LBP) exhibit altered responses to postural perturbations, and the central neural control underlying these changes in postural responses remains unclear. To characterize more thoroughly the change in muscle activation patterns of people with LBP in response to a perturbation of standing balance, and to gain insight into the influence of early- vs. late-phase postural responses (differentiated by estimates of voluntary reaction times), this study evaluated the intermuscular patterns of electromyographic (EMG) activations from 24 people with and 21 people without a history of chronic, recurrent LBP in response to 12 directions of …

The Evolution Of Lateralized Foot Use In Parrots: A Phylogenetic Approach, Culum Brown, Maria Magat

Sentience Collection

Cerebral lateralization refers to the division of cognitive function in either brain hemisphere and may be overtly expressed as behavioral asymmetries, such as handedness. The evolutionary history of laterality is of considerable interest due to its close link with the development of human language. Although considerable research effort has aimed at the proximate explanations of cerebral lateralization, considerably less attention has been paid to ultimate explanations. The extent to which laterality is constrained by phylogeny or shaped by ecological forces through natural selection has received little attention. Here, the foot preference of 23 species of Australian parrots was examined to …

The Knowledge-Driven Exploration Of Integrated Biomedical Knowledge Sources Facilitates The Generation Of New Hypotheses, Vinh Nguyen, Olivier Bodenreider, Todd Minning, Amit P. Sheth

Kno.e.sis Publications

Knowledge gained from the scientific literature can complement newly obtained experimental data in helping researchers understand the pathological processes underlying diseases. However, unless the scientific literature and experimental data are semantically integrated, it is generally difficult for scientists to exploit the two sources effectively. We argue that, in addition to the semantic integration of heterogeneous knowledge sources, the usability of the integrated resource by scientists is dependent upon the availability of knowledge visualization and exploration tools. Moreover, the integration techniques must be scalable and the exploration interfaces must be easy to use by bench scientists. The end goal of such …
