The specific objectives are to determine the advantages and disadvantages of the program, to become familiar with the perceptions of the milk according to various socioeconomic groups, and to investigate the level of awareness in order to propose strategies for development and education if necessary. Ultimately, this investigation identifies improvements to the program to satisfy the various needs of health …

Mother Goats Do Not Forget Their Kids’ Calls, Elodie F. Briefer, Mónica Padilla De La Torre, Alan G. Mcelligott

Sentience Collection

Parent–offspring recognition is crucial for offspring survival. At long distances, this recognition is mainly based on vocalizations. Because of maturation-related changes to the structure of vocalizations, parents have to learn successive call versions produced by their offspring throughout ontogeny in order to maintain recognition. However, because of the difficulties involved in following the same individuals over years, it is not clear how long this vocal memory persists. Here, we investigated long-term vocal recognition in goats. We tested responses of mothers to their kids’ calls 7–13 months after weaning. We then compared mothers’ responses to calls of their previous kids with …

Development Of Scn Connectivity And The Circadian Control Of Arousal: A Diminishing Role For Humoral Factors?, Andrew J. Gall, William D. Todd, Mark S. Blumberg

Faculty Publications

The suprachiasmatic nucleus (SCN) is part of a wake-promoting circuit comprising the dorsomedial hypothalamus (DMH) and locus coeruleus (LC). Although widely considered a "master clock," the SCN of adult rats is also sensitive to feedback regarding an animal's behavioral state. Interestingly, in rats at postnatal day (P)2, repeated arousing stimulation does not increase neural activation in the SCN, despite doing so in the LC and DMH. Here we show that, by P8, the SCN is activated by arousing stimulation and that selective destruction of LC terminals with DSP-4 blocks this activational effect. We next show that bidirectional projections among the …

Recent Advances In Integrating Owl And Rules, Matthias Knorr, David Carral Martinez, Pascal Hitzler, Adila A. Krisnadhi, Frederick Maier, Cong Wang

Computer Science and Engineering Faculty Publications

As part of the quest for a unifying logic for the Semantic Web Technology Stack, a central issue is finding suitable ways of integrating description logics based on the Web Ontology Language (OWL) with rule-based approaches based on logic programming. Such integration is difficult since naive approaches typically result in the violation of one or more desirable design principles. For example, while both OWL 2 DL and RIF Core (a dialect of the Rule Interchange Format RIF) are decidable, their naive union is not, unless carefully chosen syntactic restrictions are applied.

We report on recent advances and ongoing work by …

A Tableau Algorithm For Description Logics With Nominal Schema, Adila Krisnadhi, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We present a tableau algorithm for the description logic ALCOV. This description logic is obtained by extending the description logic ALCO with the expressive nominal schema construct that enables DL-safe datalog with predicates of arbitrary arity to be covered within the description logic framework. The tableau algorithm provides a basis to implement a delayed grounding strategy which was not facilitated by earlier versions of decision procedures for satisfiability in expressive description logics with nominal schemas.

Health Disparities Experienced By People With Disabilities In The Us: A Behavioral Risk Factor Surveillance System Study, Jennifer Renee Pharr, Timothy J. Bungum

Environmental & Global Health Faculty Research

The Americans with Disabilities Act became law in 1990; since then research has shown that people with disabilities continue to experience barriers to health care. The purpose of this study was to compare utilization of preventive services, chronic disease rates, and engagement in health risk behaviors of participants with differing severities of disabilities to those without disabilities. This study was a secondary analysis of 2010 data collected in the Behavioral Risk Factor Surveillance System national survey in the United States. Rao Chi square test and logistic regression were employed. Participants with disabilities had significantly higher adjusted odds ratios for all …

Analysis Of A Genetic Isolate: The Case Of Carloforte (Italy), R. Robledo, L. Corrias, V. Bachis, N. Puddu, A. Mameli, G. Vona, C. M. Calò

Human Biology Open Access Pre-Prints

We reviewed data collected during several studies concerning the genetic isolate of Carloforte (Sardinia, Italy) and analyzed new data on Y-chromosome markers. Carloforte is also a language island, where people still speaks Tabarchino, an archaic form of Ligurian dialect. Demographic data indicate that, in the early years of its history, Carloforte population was characterized by a high degree of endogamy and consanguinity rates that started to decrease around 1850, when marriages with Sardinian people began to occur more frequently. Cultural factors, mainly language, account for the high endogamy. Genetic data from classical markers, mtDNA and Ychromosome markers confirmed the strong …

Vocal Expression Of Emotions In Mammals: Mechanisms Of Production And Evidence, Elodie Briefer

Communication Skills Collection

Emotions play a crucial role in an animal’s life because they facilitate responses to external or internal events of significance for the organism. In social species, one of the main functions of emotional expression is to regulate social interactions. There has recently been a surge of interest in animal emotions in several disciplines, ranging from neuroscience to evolutionary zoology. Because measurements of subjective emotional experiences are not possible in animals, researchers use neurophysiological, behavioural and cognitive indicators. However, good indicators, particularly of positive emotions, are still lacking. Vocalizations are linked to the inner state of the caller. The emotional state …

Individuals With Non-Specific Low Back Pain In An Active Episode Demonstrate Temporally Altered Torque Responses And Direction-Specific Enhanced Muscle Activity Following Unexpected Balance Perturbations, Stephanie L. Jones, Juvena R. Hitt, Michael J. Desarno, Sharon M. Henry

Exercise and Sport Studies: Faculty Publications

Individuals with a history of non-specific low back pain (LBP) while in a quiescent pain period demonstrate altered automatic postural responses (APRs) characterized by reduced trunk torque contributions and increased co-activation of trunk musculature. However, it is unknown whether these changes preceded or resulted from pain. To further delineate the relationship between cyclic pain recurrence and APRs, we quantified postural responses following multi-directional support surface translations, in individuals with non-specific LBP, following an active pain episode. Sixteen subjects with and 16 without LBP stood on two force plates that were translated unexpectedly in 12 directions. Net joint torques of the …

Chronic Exercise Modifies Age-Related Telomere Dynamics In A Tissue-Specific Fashion, Andrew T. Ludlow, Sarah Witkowski, Mallory R. Marshall, Jenny Wang, Laila C.J. Lima, Lisa M. Guth, Espen E. Spangenburg, Stephen M. Roth

Exercise and Sport Studies: Faculty Publications

We evaluated the impact of long-term exercise on telomere dynamics in wild-derived short telomere mice (CAST/Ei) over 1 year. We observed significant telomere shortening in liver and cardiac tissues in sedentary 1-year-old mice compared with young (8 weeks) baseline mice that were attenuated in exercised 1-year-old animals. In contrast, skeletal muscle exhibited significant telomere shortening in exercise mice compared with sedentary and young mice. Telomerase enzyme activity was increased in skeletal muscle of exercise compared with sedentary animals but was similar in cardiac and liver tissues. We observed significant age-related decreases in expression of telomere-related genes that were attenuated by …

Rapid Range Expansion In The Great Plains Narrow-Mouthed Toad (Gastrophryne Olivacea) And A Revised Taxonomy For North American Microhylids, Jeffrey W. Streicher, Christian L. Cox, Jonathan A. Campbell, Eric N. Smith, Rafael O. De Sá

Biology Faculty Publications

We investigated genetic variation within the Great Plains narrow-mouthed toad, Gastrophryne olivacea, across its geographic range in the United States and Mexico. An analysis of mitochondrial DNA (mtDNA) from 105 frogs revealed remarkably low levels of genetic diversity in individuals inhabiting the central United States and northern Mexico. We found that this widespread matrilineal lineage is divergent (ca. 2% in mtDNA) from haplotypes that originate from the western United States and western coast of Mexico. Using a dataset that included all five species of Gastrophryne and both species of the closely related genus Hypopachus, we investigated the phylogenetic …

Reconciling Owl And Non-Monotonic Rules For The Semantic Web, Matthias Knorr, Pascal Hitzler, Frederick Maier

Computer Science and Engineering Faculty Publications

We propose a description logic extending SROIQ (the description logic underlying OWL 2 DL) and at the same time encompassing some of the most prominent monotonic and nonmonotonic rule languages, in particular Datalog extended with the answer set semantics. Our proposal could be considered a substantial contribution towards fulfilling the quest for a unifying logic for the Semantic Web. As a case in point, two non-monotonic extensions of description logics considered to be of distinct expressiveness until now are covered in our proposal. In contrast to earlier such proposals, our language has the 'look and feel' of a description logic …

Lessons Learned From Citizen Science In The Classroom. A Response To "The Future Of Citizen Science.", Steven A. Gray, Kristina Nicosia, Rebecca C. Jordan

Democracy & Education

Mueller, Tippins, and Bryan’s contrast of the current limitations of science education with the potential virtues of citizen science provides an important theoretical perspective about the future of democratized science and K–12 education. However, the authors fail to adequately address the existing barriers and constraints to moving community-based science into the classroom. We contend that for these science partnerships to be successful, teachers, researchers, and other program designers must reexamine questions about traditional science education and citizen-science programs and attend to certain dimensions, including: framing these projects around the nature of science, creating a dialog with experts and allowing access …

Valuing Improvements To Coastal Waters Using Choice Experiments: An Application To Revisions Of The Eu Bathing Waters Directive, Stephen Hynes, Dugald Tinch, Nick Hanley

Working Papers

Planned changes to the European Union’s Bathing Waters Directive (2006/7 EC) will force member states to produce improvements in a number of parameters of coastal water quality. This study uses the choice experiment method to estimate the economic benefits attached to such improvements, based on a sample of recreationalists on beaches in Ireland. The analysis indicates that improvements in all of the bathing water related attributes studied result in positive willingness to pay, and also show evidence of scope effects. Using random parameters and latent class modelling techniques, potential heterogeneity in preferences is then investigated and shown to be present …

Individual Prey Choices Of Octopuses: Are They Generalist Or Specialist?, Jennifer A. Mather, Tatiana S. Leite, Allan T. Batista

Sentience Collection

Prey choice is often evaluated at the species or population level. Here, we analyzed the diet of octopuses of different populations with the aim to assess the importance of individual feeding habits as a factor affecting prey choice. Two methods were used, an assessment of the extent to which an individual octopus made choices of species representative of those population (PSi and IS) and 25% cutoff values for number of choices and percentage intake of individual on their prey. In one population of Octopus cf vulgaris in Bermuda individuals were generalist by IS=0.77, but most chose many prey of the …

Physiology Collection

The aim of this study was to compare effects of inorganic sulfate versus chelated forms of supplemental Cu, Mn, and Zn on milk production, plasma and milk mineral concentrations, neutrophil activity, and antibody titer response to a model vaccination. Holstein cows (n = 25) were assigned in 2 cohorts based on calving date to a 12-wk randomized complete block design study. The first cohort consisted of 17 cows that had greater days in milk (DIM; mean of 77 DIM at the start of the trial) than the second cohort of 8 cows (32 DIM at the start of the trial). …

The Trade And Welfare Impacts Of Australian Quarantine Policies: The Case Of Pigmeat, John C. Beghin, Mark Melatos

Department of Agricultural Economics: Faculty Publications

We analyze the trade and welfare impact of quarantine measures imposed by Australia on imports of pigmeat. In particular, we account for changes to Australia’s pigmeat quarantine policy over time, including those changes related to the recent resolution of a WTO dispute between Australia and the European Union. Using a random utility model and applying it to corner solutions in import decisions, tariff equivalents (by major trading partner) are estimated for the different pigmeat quarantine regimes implemented by Australia during the period 1988-2009. The welfare impact on consumers, producers, and foreign exporters is computed using a partial equilibrium model calibrated …

Directed toward the EU and its trade partners, the project’s first overall objective was to collect and analyze new data on NTMs for key and representative agri-food products. This involved three components: creating a large symmetric international database on the diverse types of governmental standards and regulations used to address food safety and quality issues, constructing measures of heterogeneity among these standards and regulations; and evaluating the …

Design From Within: A Resident-Based Approach To Nursing Home Design, Maureen D. Carland Ma

All Student Scholarship

This paper examined the value and impact of obtaining stakeholder input in the design of long-term care facilities. Most previous literature focused on obtaining input from an architect’s or nurse’s perspective, and very few studies have analyzed input from the residents—the primary stakeholder (Woo, Mak, Cheng & Choy, 2011). Specifically, this paper identifies and examines stakeholder input at The Maine Veterans’ Home in Scarborough, Maine.

Weaponizing Tear Gas: Bahrain’S Unprecedented Use Of Toxic Chemical Agents Against Civilians., Richard Sollom, Holly G. Atkinson

Publications and Research

The Bahraini government’s response to the early 2011 pro-democracy protests was brutal, systematic, and violent. In addition to birdshot and rubber bullets, government law enforcement attacked unarmed protestors with toxic chemical agents including tear gas. The government’s crackdown on the medical profession was especially harmful, as security forces arrested and detained doctors, raided health facilities, and obstructed patients from receiving necessary care. This report’s findings are based on field research that the authors conducted in Bahrain (April 2012) to investigate excessive use of force by law enforcement officials since June 2011—the end of Bahrain’s state of emergency. The medico-legal team …

Investing In An Agricultural Legacy, Leo Paul Goeringer

Graduate Theses and Dissertations

America's agricultural producers continue to age. According to the U.S. Census of Agriculture, the average age of farm operators increased from 55.3 in 2002 to 57.1 in 2007. During the same period, the Census shows a thirty percent decrease in the number of farmers under age 25. Young and beginning producers (YBPs) entering agriculture face high startup costs and a shortage of land to own or rent.

With these concerns in mind, this manuscript details the impact of an innovative proposed loan program for YBPs in Arkansas, which would offer concessionary interest rates and loan fees by participating banks for …

Using Attribute Behavior Diversity To Build Accurate Decision Tree Committees For Microarray Data, Qian Han, Guozhu Dong

Kno.e.sis Publications

DNA microarrays (gene chips), frequently used in biological and medical studies, measure the expressions of thousands of genes per sample. Using microarray data to build accurate classifiers for diseases is an important task. This paper introduces an algorithm, called Committee of Decision Trees by Attribute Behavior Diversity (CABD), to build highly accurate ensembles of decision trees for such data. Since a committee's accuracy is greatly influenced by the diversity among its member classifiers, CABD uses two new ideas to "optimize" that diversity, namely (1) the concept of attribute behavior–based similarity between attributes, and (2) …

Paternal Lineage Analysis Supports An Armenian Rather Than A Central Asian Genetic Origin Of The Hamshenis, Ashot Margaryan, Ashot Harutyunyan, Zaruhi Khachatryan, Armine Khudoyan, Levon Yepiskoposyan

Human Biology Open Access Pre-Prints

The Hamshenis are an isolated geographic group of Armenians with a strong ethnic identity who, until the early decades of the twentieth century, inhabited the Pontus area on the southern coast of the Black Sea. Scholars hold alternative views on their origin, proposing eastern Armenia, western Armenia and Central Asia, respectively, as their most likely homeland. To ascertain whether genetic data from the non-recombining portion of the Y chromosome is supportive any of these suggestions, we screened 82 Armenian males of the Hamsheni descent for 12 biallelic and 6 microsatellite Y-chromosomal markers. These data were compared with the corresponding datasets …

The Evolution Of Natural Plant Communities Through Crop Migration And Crop-To-Weed Gene Flow, Meredith G. Schafer

Graduate Theses and Dissertations

With the rising demand for food and biofuels, the efficiency of crop production has become vital to assuring food security. Genetically engineered (GE) crop varieties are broadly thought to be a solution for improving the efficiency of crop production, but concerns regarding their release have heightened as more discoveries have focused on the influence of genetically engineered crops on native and weedy plant species. Risk assessment of GE crop varieties focuses on two main areas: feralization of crop systems and crop-weed hybridization. Risks include naturalization, transgene introgression, and the formation of novel genotypes in natural systems. In this study, roadside …
