Emerging Dynamics Of Human Campylobacteriosis In Southern Ireland, Susan Bullman, Daniel Corcoran, James O'Leary, Derry O'Hare, Brigid Lucey, Roy D. Sleator

Department of Biological Sciences Publications

Infections with Campylobacter spp. pose a significant health burden worldwide. The significance of Campylobacter jejuni/Campylobacter coli infection is well appreciated but the contribution of non-C. jejuni/C. coli spp. to human gastroenteritis is largely unknown. In this study, we employed a two-tiered molecular study on 7194 patient faecal samples received by the Microbiology Department in Cork University Hospital during 2009. The first step, using EntericBio® (Serosep), a multiplex PCR system, detected Campylobacter to the genus level. The second step, utilizing Campylobacter species-specific PCR identified to the species level. A total of 340 samples were confirmed as Campylobacter genus positive, 329 of …

Using A Multi-Sensory Teaching Approach To Impact Learning And Community In A Second Grade Classroom, Melissa Stoffers

Theses and Dissertations

The purpose of this study was to examine how multi-sensory education impacts learning and community in a second grade general education classroom. Lesson plans that targeted multiple senses - and oftentimes included team-building activities - were developed and implemented in the classroom. Qualitative data was collected through interviews, focus groups, student work, and a teacher research journal. After analyzing the data, it was revealed that multi-sensory education can lead to student motivation and engagement, as well as provide a generative space for the use of technology and making connections to the outside world. Multi-sensory education can also help teachers to …

Photodissociation Of N2O: Energy Partitioning, Johan A. Schmidt, M. S. Johnson, U. Lorenz, George C. Mcbane, Reinhard Schinke

Peer Reviewed Articles

The energy partitioning in the UV photodissociation of N₂O is investigated by means of quantum mechanical wave packet and classical trajectory calculations using recently calculated potential energy surfaces. Vibrational excitation of N₂ is weak at the onset of the absorption spectrum, but becomes stronger with increasing photon energy. Since the NNO equilibrium angles in the ground and the excited state differe by about 70°, the molecule experiences an extraordinarily large torque during fragmentation producing N₂in very high rotational states. The vibrational and rotational distributions obtained from the quantum mechanical and the classical calculations agree remarkably …

Who’S Pandemic Influenza Preparedness Framework: A Milestone In Global Governance For Health, Lawrence O. Gostin, David P. Fidler

Georgetown Law Faculty Publications and Other Works

In May 2008, the World Health Organization (WHO) adopted the Pandemic Influenza Preparedness Framework for the Sharing of Influenza Viruses and Access to Vaccines and Other Benefits (PIP Framework). The PIP Framework’s adoption ended years of difficult negotiations, which began after Indonesia refused to share samples of avian influenza A (H5N1) with WHO in late 2006. Indonesia justified its actions on the need to create more equitable access for developing countries to benefits, such as vaccines and antivirals, derived from research and development on shared influenza virus samples. The global health community feared that failure to share influenza virus samples …

Antecedents And Continuity Of Compliance In Preschoolers, Lauren Gindin

Master's Theses

Self-regulation, and compliance behavior specifically, has been implicated in the development of successful socialization. Difficulty self-regulating has led to negative outcomes in areas such as academic success and mental health, and a number of possible contributors, such as temperament, maternal sensitivity and attachment, have been identified. In this study, we examined these possible predictors of preschool compliance behavior through causal modeling utilizing a large and diverse longitudinal dataset from the NICHD Study of Early Child Care and Youth Development. We aimed to predict compliance and delay of gratification performance in children across 2, 3 and 4.5 years of age by …

Naive Bayesian Spam Filters For Log File Analysis, Russel William Havens

Theses and Dissertations

As computer system usage grows in our world, system administrators need better visibility into the workings of computer systems, especially when those systems have problems or go down. Most system components, from hardware, through OS, to application server and application, write log files of some sort, be it system-standardized logs such syslog or application specific logs. These logs very often contain valuable clues to the nature of system problems and outages, but their verbosity can make them difficult to utilize. Statistical data mining methods could help in filtering and classifying log entries, but these tools are often out of the …

Species Interactions During Diversification And Community Assembly In An Island Radiation Of Shrews, Jacob A. Esselstyn, Sean P. Maher, Rafe M. Brown

College of Natural and Applied Sciences

Background: Closely related, ecologically similar species often have adjacent distributions, suggesting competitive exclusion may contribute to the structure of some natural communities. In systems such as island archipelagos, where speciation is often tightly associated with dispersal over oceanic barriers, competitive exclusion may prevent population establishment following inter-island dispersal and subsequent cladogenesis.

Methodology/Principal Findings: Using a combination of tools, we test the hypothesis that the distributions of shrew (Crocidura) species in the Philippines are the result of competitive exclusion preventing secondary invasion of occupied islands. We first compare ecological niche models between two widespread, allopatric species and find statistical support for …

A Unified Approach To Non-Negative Matrix Factorization And Probabilistic Latent Semantic Indexing, Karthik Devarajan, Guoli Wang, Nader Ebrahimi

COBRA Preprint Series

Non-negative matrix factorization (NMF) by the multiplicative updates algorithm is a powerful machine learning method for decomposing a high-dimensional nonnegative matrix V into two matrices, W and H, each with nonnegative entries, V ~ WH. NMF has been shown to have a unique parts-based, sparse representation of the data. The nonnegativity constraints in NMF allow only additive combinations of the data which enables it to learn parts that have distinct physical representations in reality. In the last few years, NMF has been successfully applied in a variety of areas such as natural language processing, information retrieval, image processing, speech recognition …

Religion And Infant Mortality In The U.S.: A Preliminary Study Of Denominational Variations, John P. Bartkowski, Xiaohe Xu, Ginny Garcia-Alexander

Sociology Faculty Publications and Presentations

Prior research has identified a number of antecedents to infant mortality, but has been focused on either structural (demographic) forces or medical (public health) factors, both of which ignore potential cultural influences. Our study introduces a cultural model for explaining variations in infant mortality, one focused on the role of community-level religious factors. A key impetus for our study is well-established religious variations in adult mortality at the community level. Seeking to extend the growing body of research on contextual-level effects of religion, this study examines the impact of religious ecology (i.e., the institutional market share of particular denominational traditions) …

Methods and systems for realizing high resolution three-dimensional (3-D) optical imaging using diffraction limited low' resolution optical signals. Using axial shift-based signal processing via computer based computation algorithm, three sets of high resolution optical data are detennined along the axial (or light beam propagation) direction using low resolution axial data. The three sets of low resolution data are generated by illuminating the 3~D object under observation along its three independent and orthogonal look directions (i.e., x. Y. and z) or by physically rotating the object by 90 degrees and also flipping the object by 90 degrees. The three sets of …

The Effect Of Postpartum Depression On Child Cognitive Development, Joshua Lees

Theses and Dissertations

The incidence of postpartum depression (PPD) in Western societies is approximately 10-15% and its cause is multi-faceted. Because mothers largely constitute infants' social environment and mediate their experience of the external world, it is imperative to investigate the effects of PPD on child growth and development. Within this paper, the author explores previously conducted Post-Partum Depression research, in regards to its effects on child cognitive development. Following this literature review, a brief experimental study is conducted and explained on a sample population of mothers' of special needs children, serviced by an Early Intervention provider. During this experimental analysis, the researcher …

Calcineurin Is Required For Trpv1-Induced Ltd Of Ca1 Stratum Radiatum Interneurons, Tyron Deray Jensen

Theses and Dissertations

Learning and memory in the brain are thought to be dependent on synaptic plasticity. In response to sensory input, synapses can be strengthened or weakened, known as long-term potentiation or long-term depression (LTD), respectively. Transient receptor potential vanilloid 1 (TRPV1) has been shown to mediate a novel form of presynaptic LTD in hippocampal interneurons. TRPV1 is currently being heavily studied in the PNS and being targeted by pharmaceuticals for its anti-nociceptive and anti-inflammatory properties. However, much less is known regarding TRPV1 function in the CNS, including the signal mechanism mediating hippocampal LTD despite its obvious importance. Here we performed whole-cell …

Characterization Of The Serologic Responses To Plasmodium Vivax Dbpii Variants Among Inhabitants Of Pursat Province, Cambodia, Samantha Jones Barnes

USF Tampa Graduate Theses and Dissertations

The Plasmodium vivax Duffy Binding Protein (DBP) is the ligand in the major pathway for P. vivax invasion of human reticulocytes, making it an appealing vaccine candidate. Region II of DBP (DBP-RII) is the minimal portion of the ligand that mediates recognition of the Duffy Antigen Receptor for Chemokines (DARC receptor) on the reticulocyte surface and constitutes the primary vaccine target. Analysis of natural variation in the coding sequences of DBP-RII revealed signature evidence for selective pressure driving variation in the residues of the putative receptor-binding site. We hypothesize that anti-DBP immunity in P. vivax infections is strain-specific and hindered …

Note On The Assumption Of Hydrologic Stationarity, Nicholas C. Matalas

Journal of Contemporary Water Research and Education

Recent arguments that empirical evidence points to
hydrologic nonstationarity that is a consequence of
climate change cannot be dismissed. Yet the operational
assumption of hydrologic stationarity used extensively in
water management should not be discarded without
further study. It remains to be determined if assumed
forms of hydrologic nonstationarity would tax the ability
of water systems, through their robustness and resilience,
to absorb the additional stresses that would follow from
those assumptions. One approach to making the
determination is by way of an assessment of the expected
economic regret in water management resulting from the
use of the assumption of …

Biology Department Faculty Works

Invasive species can displace natives, and thus identifying the traits that make aliens successful is crucial for predicting and preventing biodiversity loss. Pathogens may play an important role in the invasive process, facilitating colonization of their hosts in new continents and islands. According to the Novel Weapon Hypothesis, colonizers may out-compete local native species by bringing with them novel pathogens to which native species are not adapted. In contrast, the Enemy Release Hypothesis suggests that flourishing colonizers are successful because they have left their pathogens behind. To assess the role of avian malaria and related haemosporidian parasites in the global …

The Culture Of Skydiving, Steven Wade

Mahurin Honors College Capstone Experience/Thesis Projects

ABSTRACT

The culture of skydiving is made up of a community of individuals who regularly jump at a given drop zone. This culture places a high value on individual achievement, self-reliance, and adherence to routine, and it promotes a strong sense of community among its members. The relationships formed between skydivers through the common experience of skydiving go beyond the activity itself. Skydive Kentucky in Elizabethtown supports its community through several unique rites of passage as an individual gradually becomes a member of the group. This drop zone also hosts cookouts and card games for its regular members. Throughout this …
