Effects Of Chocolate On A Person’S Immediate Mood, Aaron Tighe, Katherine Hannemann

Undergraduate Psychology Research Methods Journal

The following presents a study of chocolate and its effect on a person’s immediate mood. Prior research has suggested that chocolate affects a person biologically through neurotransmitters in the brain which can lead to an elevation in a person’s mood. Our study hopes to take this evidence a step further and discover if chocolate can alter one’s mood immediately, or if the chemicals in chocolate are released gradually, taking longer to affect a person’s mood. The participants were mainly recruited through the Human Subject Pool at Lindenwood University and were administered two surveys: one before a treat was consumed, and …

The Gospel Of Cosmopolitanism: Conflict Resolution In Barbara Kingsolver's Fiction, Catherine Altmaier

Masters Theses & Specialist Projects

Despite Barbara Kingsolver's ability to create unique characters and storylines, two factors remain constant throughout each of her novels: strong female protagonists and conflict resolution. Though conflict exists in almost all fiction, the way that Kingsolver's characters deal with their situations often speaks louder than any other aspect of her writing. Moreover, though her characters often vary wildly from story to story, their methods of conflict resolution seem to undoubtedly connect them. Through her continuing desire to emphasize "the question of individualism and communal identity," {Reading Group Guides) Kingsolver often promotes the ideas of cosmopolitanism, which have recently been articulated …

Unexpected Diversity And Complexity Of The Guerrero Negro Hypersaline Microbial Mat, Ruth E. Ley, J. Kirk Harris, Joshua Wilcox, John R. Spear, Scott R. Miller, Brad M. Bebout, Julia A. Maresca, Donald A. Bryant, Mithcell L. Sogin, Norman R. Pace

Biological Sciences Faculty Publications

We applied nucleic acid-based molecular methods, combined with estimates of biomass (ATP), pigments, and microelectrode measurements of chemical gradients, to map microbial diversity vertically on a millimeter scale in a hypersaline microbial mat from Guerrero Negro, Baja California Sur, Mexico. To identify the constituents of the mat, small-subunit rRNA genes were amplified by PCR from community genomic DNA extracted from layers, cloned, and sequenced. Bacteria dominated the mat and displayed unexpected and unprecedented diversity. The majority (1,336) of the 1,586 bacterial 16S rRNA sequences generated were unique, representing 752 species (>= 97% rRNA sequence identity) in 42 of the …

What Use Is Half A Wing In The Ecology And Evolution Of Birds?, Kenneth P. Dial, Ross J. Randall, Terry R. Dial

Biological Sciences Faculty Publications

The use of incipient wings during ontogeny in living birds reveals not only the function of these developing forelimbs in growing birds’ survival but also the possible employment of protowings during transitional stages in the evolution of flight. When startled, juvenile galliform birds attempt aerial flight even though their wings are not fully developed. They also flap their incipient wings when they run up precipitous inclines, a behavior we have described as wing-assisted incline running (WAIR), and when they launch from elevated structures. The functional benefit of beating these protowings has only recently been evaluated. We report the first ontogenetic …

Fisheries Research Report No. 155 - Identification Of Western Australian Grey Nurse Shark Aggregation Sites., J. Chidlow, Daniel J. Gaughan, Rory Mcauley

Fisheries Research Reports

Final report to the Australian Government, Department of the Environment and Heritage

The first phase of this project involved a desktop study to broadly identify areas where Western Australian Grey Nurse Sharks potentially aggregate for further investigation with field surveys. These areas were identified from information obtained from commercial shark fishers, previously unpublished research data, as well as anecdotal reports of sightings or captures from recreational divers and fishers, professional dive stores, dive clubs and charter boat operators. A total of 25 survey areas were identified during the desktop study, 16 of which were in depths less than 30m and …

B Cells At The Interface Of Innate And Adaptive Immunity In Systemic Lupus Erythematosus: Requirements For The Activation Of Autoreactive B Cells In Autoimmune Disease, Sean Ryan Christensen

Yale Medicine Thesis Digital Library

Systemic autoimmune disease is characterized by loss of immunologic tolerance to a restricted set of self-nuclear antigens. These macromolecular complexes can be grouped into two categories: DNA-containing autoantigens such as chromatin, and RNA containing autoantigens such as Smith antigen (Sm) and related ribonucleoprotein complexes. Elucidating the mechanism for selective targeting of these molecules in systemic lupus erythematosus (SLE) may provide clues to the etiology of disease. We hypothesized that Toll-like receptors (TLRs), germline-encoded pattern-recognition receptors of the innate immune system, could dictate target antigen specificity in SLE. Using genetic ablation of various TLRs in murine models of SLE, we have …

Turing Pattern Dynamics For Spatiotemporal Models With Growth And Curvature, Julijana Gjorgjieva

HMC Senior Theses

Turing theory plays an important role in real biological pattern formation problems, such as solid tumor growth and animal coat patterns. To understand how patterns form and develop over time due to growth, we consider spatiotemporal patterns, in particular Turing patterns, for reaction diffusion systems on growing surfaces with curvature. Of particular interest is isotropic growth of the sphere, where growth of the domain occurs in the same proportion in all directions. Applying a modified linear stability analysis and a separation of timescales argument, we derive the necessary and sufficient conditions for a diffusion driven instability of the steady state …

Geochemistry Of Benthic Foraminifera As An Environmental Indicator: A Study From Multiple Hydrographic Regimes, Chandranath Basak

All-Inclusive List of Electronic Theses and Dissertations

The geochemistry (stable isotopes and Lracc clements) or living (sLaincd) calcareous benthic foraminifera was compared with ambient botlom water stable isotope values to provide modern analog conditions and calibrations for environmental and paleoenvironmental assessments. Stable isotope values of live (stained) bcnthic foraminifera were investigated from push core and multicorer samples from the North Pacific (on the Aleutian margin, water depth 1988m) and the South Australian Bight (water depth 2476m and 1634m). Living benthic foraminifera specimens collected from contaminated sites in the Venice Lagoon were analyzed for trace elements. Both the isotopic and the trace element study involved interpretation of modern …

Rapid Assimilation Of Yolk Enhances Growth And Development Of Lizard Embryos From A Cold Environment, Melissa Ann Blake

All-Inclusive List of Electronic Theses and Dissertations

Selection for rapid growth in cold environments results in a geographic pattern known as countergradient variation. The eastern fence lizard, Sceloporus undulatus, exhibits countergradient variation in growth rate across latitudinal clines. In a common-garden experiment, S. undulatus embryos from cold environments grew more efficiently than embryos warm environments, even when the energetic contents of eggs were equalized. To examine the physiological mechanisms of higher growth efficiency, I measured the energetics of embryos during the first 49 days of incubation. Specifically, I recorded body mass, residual yolk, total respiration, and developmental stage for embyos from two populations (Virginia and South Carolina). …

The Exponential Function, Shawn A. Mousel

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

One of the basic principles studied in mathematics is the observation of relationships between two connected quantities. A function is this connecting relationship, typically expressed in a formula that describes how one element from the domain is related to exactly one element located in the range (Lial & Miller, 1975). An exponential function is a function with the basic form f (x) = ax , where a (a fixed base that is a real, positive number) is greater than zero and not equal to 1. The exponential function is not to be confused with the polynomial functions, such as x2. …

Analysis Of Distal-Less Gene Expression In Ciona Intestinalis, Michelle Cangiano

Senior Honors Projects

Several homeobox-containing genes related to Distal-less (Dlx/Dll) have been isolated from a wide variety of organisms and have been shown to function as developmental regulators. In Drosophila only one Distal-less gene has been identified so far, and in vertebrates many components of the Distal-less family have been characterized. This suggests that, during the evolution of the Chordate phylum, the Dlx genes arose from an ancestral Distal-less gene via gene duplication. Three Dll homeoboxes have been isolated from the protochordate Ciona intestinalis and their clustered arrangement has been described. Since Ciona is regarded as one of the most primitive extant chordates, …

Bilinear Models From System Approach Justified For Classification, With Potential Applications To Bioinformatics, Richard Aló, Francois Modave, Vladik Kreinovich, David Herrera, Xiaojing Wang

Departmental Technical Reports (CS)

When we do not know the dynamics of a complex system, it is natural to use common sense to get a reasonable first approximation -- which turns out to be a bilinear dynamics. Surprisingly, for classification problems, a similar bilinear approximation turns out to be unexpectedly accurate. In this paper, we provide an explanation for this accuracy.

Narrowed Tcr Repertoire And Viral Escape As A Consequence Of Heterologous Immunity, Markus Cornberg, Alex T. Chen, Lee A. Wilkinson, Michael A. Brehm, Sung-Kwon Kim, Claudia Calcagno, Dario Ghersi, Roberto Puzone, Franco Celada, Raymond M. Welsh, Liisa K. Selin

Interdisciplinary Informatics Faculty Publications

Why some virus-specific CD8 TCR repertoires are diverse and others restricted or “oligoclonal” has been unknown. We show here that oligoclonality and extreme clonal dominance can be a consequence ofTcell crossreactivity. Lymphocytic choriomeningitis virus (LCMV) and Pichinde virus (PV) encode NP205–212 epitopes that induce different but highly cross-reactive diverseTCRrepertoires. Homologous viral challenge ofimmune mice only slightly skewed the repertoire and enriched for predictable TCR motifs. However, heterologous viral challenge resulted in a narrow oligoclonal repertoire with dominant clones with unpredictableTCRsequences.This shift in clonal dominance varied with the private, i.e., unique, specificity of the host’s TCR repertoire and was simulated using …

Assessing Past Strategies For Countering Terrorism, In Lebanon And By Libya, Louis Kriesberg

Peace and Conflict Studies

American strategies to deal with terrorist attacks against Americans in Lebanon in the 1980s and by Libya since the beginning of the 1980s are examined. The consequences of the various strategies employed by U.S. government officials over time and the strategies employed by American non-governmental actors and by international organizations are compared. In addition, alternative strategies that might plausibly have been employed are also discussed. Official actions that relied largely on military methods and were conducted unilaterally tended to be less effective, even counterproductive, compared to actions that were multilateral and relied significantly on diplomatic approaches, often aided by intermediaries.

Something Must Be Done: An Argument For The Partial Deregulation Of Research On Bipolar Disorder And The Implementation Of Rolling Informed Consent, Janalee S. Kraschnewski

University of Michigan Journal of Law Reform

Bipolar disorder (BD) cripples the lives of countless individuals across the globe. The healthcare community has had difficulty securing effective, long-term treatment for this disease. This Note argues that enlarging the pool of possible research subjects through partial deregulation of BD research would facilitate the development of better treatment. This Note further proposes the implementation of a system of rolling informed consent to ensure that actual and full consent is obtained from BD research subjects.

On The Geomorphology, Hydrology, And Biogeochemistry Of Stream-Lake Interactions In The Sawtooth Mountains, Idaho, Usa, Christopher D. Arp

Biology

This dissertation focuses on the geomorphology, hydrology, and biogeochemistry of streams and lakes as coupled, interacting ecosystems in the Sawtooth Mountains, Idaho, USA. The study design used intensive field studies of several ecosystems nested within a broader comparative study of many ecosystems. Stream geomorphology was affected by lakes due to the glacial legacy of lakes and subsequent modification of water and sediment flux. Hydrologically, streams below lakes had more frequent and longer duration floods, and lakes were shown to attenuate summer floods, but not spring snowmelt floods. Biogeochemically, nutrient uptake among streams showed high phosphate and low nitrate uptake downstream …

Evolutionary Consequences Of An Introduced Predator: Adaptive Change In Daphnia Melanica In Response To Exotic Salmonids In The Sierra Nevada, Debra L. Fisk

Biology

The introduction of exotic species into a novel habitat, like all drastic environmental alterations, can lead to rapid evolution of both native and exotic species. Few studies have focused on the rapid adaptive evolution of native species to the introduction of a foreign species. Therefore, I wanted to determine if the introduction of exotic size-selective predators (salmonids) to alpine lakes in the Sierra Nevada, CA, has led to an adaptive response in the native prey species, Daphnia melanica. I conducted two common garden experiments with D. melanica from multiple populations, and collected data for morphological and life-history traits. With …
