Alfred Russel Wallace Notes 14: Background For Wallace's 1845 Kington Essay, Charles H. Smith Nov 2020

Alfred Russel Wallace Notes 14: Background For Wallace's 1845 Kington Essay, Charles H. Smith

Faculty/Staff Personal Papers

‘An Essay, On the Best Method of Conducting the Kington Mechanic's Institution’ is one of the earliest written works by Alfred Russel Wallace (1823−1913) known to have reached print. The circumstances of its writing are still not clear, though I here review pertaining facts and theories that seem to indicate Wallace actually was the author of the essay, which had been questioned.


Alfred Russel Wallace Notes 13: Wallace On Prayer, Charles H. Smith Nov 2020

Alfred Russel Wallace Notes 13: Wallace On Prayer, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) is known to most for his natural history explorations and theoretical biology, but he also developed thoughts on a number of subjects relatable to a wider appreciation of evolutionary cosmology. His adoption of spiritualism, for one, was attuned to this mission, and in turn his otherwise difficult-to-interpret two-sided position on prayer.


Alfred Russel Wallace Notes 12: How Good Was Wallace's Memory?, Charles H. Smith Nov 2020

Alfred Russel Wallace Notes 12: How Good Was Wallace's Memory?, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) continues to be criticized for inconsistencies in his recollections of the earlier events in his life. This criticism, while not entirely unjust, has nevertheless been overplayed. Critics have not attended to the general understanding that self-biography is under the influence of two aspects of memory: that pertaining to remembrance of the qualities of past situations, and a secondary ability to assign absolutes of name or date to such memories. All evidence suggests that Wallace’s memory in the first sense was excellent throughout his life, but that he was prone to lapses of the second type.

Validation Of A Novel Vo2max Protocol, Griffin Green Apr 2020

Validation Of A Novel Vo2max Protocol, Griffin Green

Masters Theses & Specialist Projects

Though there are several to choose from, the Bruce protocol is the most commonly utilized treadmill protocol when assessing maximal oxygen consumption (VO2max). Originally developed for cardiac patients, the Bruce protocol may not be an appropriate treadmill protocol for young or trained individuals with higher levels of cardiorespiratory fitness. The steep grade used often leads localized muscular fatigue, which may cause participants to end the test prior to reaching their true VO2max. Another popular protocol, the Astrand, also utilizes a steep grade, but the speed remains constant. Similar to the Bruce, the Astrand protocol may not prompt a maximal cardiovascular …


Effects Of Alpha- And Beta-Adrenergic Receptor Blockade Upon Inflammatory Responses To Acute And Chronic Sleep Fragmentation, Nicholas David Wheeler Apr 2020

Effects Of Alpha- And Beta-Adrenergic Receptor Blockade Upon Inflammatory Responses To Acute And Chronic Sleep Fragmentation, Nicholas David Wheeler

Masters Theses & Specialist Projects

Generally, sleep is viewed as a recuperative process and its dysregulation has

cognitive, metabolic, immunological, and inflammatory implications that are largely deleterious to human health. Epidemiological and empirical studies have suggested that sleep fragmentation (SF) as result of obstructive sleep apnea (OSA) and other sleep abnormalities leads to pronounced systemic inflammatory responses, which are influenced by the sympathetic nervous system (SNS). However, the underlying molecular mechanisms contributing to SNS regulation of SF-induced inflammatory states are not fully understood. To assess the effects of the SNS system, C57BL/6j female mice were placed in automated SF chambers (12L:12D) and subjected to either …

Inflammatory Bowel Disease Diagnosis Using Metagenomic Classification, Michael Riggle

Masters Theses & Specialist Projects

Inflammatory bowel disease (IBD) is a set of disorders that involve chronic inflammation of digestive tracts, e.g., Crohn's disease (CD) and ulcerative colitis (UC). Millions of people around the world have inflammatory bowel disease. However, it is still difficult to treat IBD due to its unknown cause. In fact, accurately diagnosing inflammatory bowel disease (IBD) can be very challenging too since some of IBD symptoms can mimic those of other conditions. In this work, we apply classification methods to help improve the success rate of diagnosis. We study four formulations of IBD classification: i) IBD and non-IBD (binary classification), ii) …

Bodyweight Management And Relationship To Health In The Horse (Equus Caballus), Beverly Ann Gartland

Masters Theses & Specialist Projects

The health of the horse is of interest to animal caretakers. Horses that fall within a prescribed range of bodyweight and body condition may be healthier than horses that are lower or higher. Two studies were conducted related to body weight and condition of the horse. The first study examined if restricting the amount of space available for horses to graze could reduce bodyweight without having a strong impact on time budgets of the horse or removing horses from pasture. This method was determined to be effective in preventing weight gain, although there was an increase in grazing behavior displayed …

Does Infant Temperament And Parental Involvement Influence Infant Cardiac Physiological Regulation?, Mary Richter Apr 2020

Does Infant Temperament And Parental Involvement Influence Infant Cardiac Physiological Regulation?, Mary Richter

Masters Theses & Specialist Projects

The ability to self-regulate allows infants to stay at a baseline level during periods of stress (Porges, 1995). Baseline respiratory sinus arrhythmia (RSA) may be used as an indicator of self-regulation and how well an individual can respond to changes in the environment (Stifter & Corey, 2001). Differences in infant temperament can influence a child’s ability to self-regulate (Dale et al., 2011), but moderators of this relationship have not been thoroughly examined in the literature. Parents who are more involved might have more opportunities to teach children important regulatory strategies (Blandon et al., 2010). The current study examined the association …


Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel Apr 2020

Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel

Masters Theses & Specialist Projects

Substrate-borne vibrations, or biotremors, are utilized by vertebrates found in unique environments because biotremors are an effective way to transmit signals through dense media. Previous studies have shown that veiled chameleons (Chamaeleo calyptratus) are able to produce biotremors via specialized neck muscles. I hypothesized that during courtship and/or breeding, the veiled chameleon, a tree-dwelling species, would communicate with biotremors through branches. Additionally, I hypothesized that female call characteristics would differ between reproductive condition (i.e., receptive and non-receptive), while male call characteristics would differ between behavioral contexts (i.e., territorial vs. courtship). Chameleons were paired (one male, one female) and placed on …


Effects Of Pharmacologically-Induced Sleep Loss On Parental Care In Arctic-Breeding Songbirds, Wesley Payette Apr 2020

Effects Of Pharmacologically-Induced Sleep Loss On Parental Care In Arctic-Breeding Songbirds, Wesley Payette

Masters Theses & Specialist Projects

Sleep loss is well known to impair cognitive function, immunological responses, and general well-being in humans. However, sleep requirements in mammals and birds may vary dramatically, especially with changes in environment. In circumpolar regions with continuous light, sleep requirements may be little, particularly in breeding birds. The effects of sleep loss on several fitness parameters were examined in two species of Arctic-breeding passerine birds: Lapland longspurs (Calcarius lapponicus) and snow buntings (Plectrophenax nivalis). Adult males were implanted during the nestling phase (4 days post-hatch) with osmotic pumps containing an anti-narcolepsy drug, modafinil, to extend the active period for 72 h. …

Toxicity Of Novel Platinum Compounds In Mammalian Cancer Cells, Vanesa Veletanlic Apr 2020

Toxicity Of Novel Platinum Compounds In Mammalian Cancer Cells, Vanesa Veletanlic

Masters Theses & Specialist Projects

There are currently three FDA platinum compounds approved for use as chemotherapeutics, where each drug has variable efficacies for different cancer types depending on cancer’s tissue of origin. The approved compounds are platinum(II) complexes with four coordination sites on the platinum atom allowing two types of ligands to attach: leaving ligands, which are removed from the platinum atom in solution, and non-leaving ligands, which remain complexed to the platinum. Carboplatin, the preferred compound used to treat ovarian and small-cell lung cancers, has a characteristic cyclobutanedicarboxylic acid leaving ligand and two ammonia non-leaving ligands. A novel compound, 1,1-cyclobutanedicarboxylato(ethylenediamine)platinum (II), or Pt(en)CBDCA, …
