Spiders Or Butterflies? Despite Student Preference, Gender-Biased Lesson Models Do Not Impact Interest, Attitude, And Learning In Biology, Amy N. Buxton Mar 2015

Spiders Or Butterflies? Despite Student Preference, Gender-Biased Lesson Models Do Not Impact Interest, Attitude, And Learning In Biology, Amy N. Buxton

Theses and Dissertations

Educational research often emphasizes the prevalent gender gap between males and females in science, technology, engineering, and mathematics (STEM) fields. While many studies have found a gender bias when it comes to specific areas of science, little has been done to analyze the effects of how we teach within each of these subjects. In our study, we took a new angle on gender research by specifically considering whether there is a gender gap in how the models (the specific lesson examples/content used to teach a broader biology topic) used to teach biology affect student interest, attitude, and learning. We first …

Latitudinal Variation In Lifetime Survival And Reproduction In A Burying Beetle, Clinton T. Laidlaw Mar 2015

Latitudinal Variation In Lifetime Survival And Reproduction In A Burying Beetle, Clinton T. Laidlaw

Theses and Dissertations

Temperature variation experienced across a latitudinal range is tied to changes in lifespan and life history across multiple taxa. Two patterns of adaptation to latitudinal temperature variation have been documented – counter-gradient (or co-gradient) variation, and local adaptation. To determine how natural selection has shaped life history variation in a burying beetle, Nicrophorus orbicollis, we quantified lifetime patterns of reproduction in two populations that represent the geographic and temperature extremes occupied by the species. Lifetime reproduction was quantified at two temperatures that represented conditions typical for each population. Burying beetles from different extremes of their geographic range show considerable variation …

Nanoparticle Properties And Synthesis Effects On Surface-Enhanced Raman Scattering (Sers) Enhancement Factor: An Introduction, Nathan D. Israelsen, Cynthia Hanson, Elizabeth Vargis Mar 2015

Nanoparticle Properties And Synthesis Effects On Surface-Enhanced Raman Scattering (Sers) Enhancement Factor: An Introduction, Nathan D. Israelsen, Cynthia Hanson, Elizabeth Vargis

Biological Engineering Faculty Publications

Raman spectroscopy has enabled researchers to map the specific chemical makeup of surfaces, solutions, and even cells. However, the inherent insensitivity of the technique makes it difficult to use and statistically complicated. When Raman active molecules are near gold or silver nanoparticles, the Raman intensity is significantly amplified. This phenomenon is referred to as surface-enhanced Raman spectroscopy (SERS). The extent of SERS enhancement is due to a variety of factors such as nanoparticle size, shape, material, and configuration. The choice of Raman reporters and protective coatings will also influence SERS enhancement. This review provides an introduction to how these factors …

Characterization Of 3d Voronoi Tessellation Nearest Neighbor Lipid Shells Provides Atomistic Lipid Disruption Profile Of Protein Containing Lipid Membranes, Sara Y. Cheng, Hai Viet Duong, Campbell Compton, Mark W. Vaughn, Hoa Nguyen, Kwan H. Cheng Mar 2015

Characterization Of 3d Voronoi Tessellation Nearest Neighbor Lipid Shells Provides Atomistic Lipid Disruption Profile Of Protein Containing Lipid Membranes, Sara Y. Cheng, Hai Viet Duong, Campbell Compton, Mark W. Vaughn, Hoa Nguyen, Kwan H. Cheng

Physics and Astronomy Faculty Research

Quantifying protein-induced lipid disruptions at the atomistic level is a challenging problem in membrane biophysics. Here we propose a novel 3D Voronoi tessellation nearest-atom-neighbor shell method to classify and characterize lipid domains into discrete concentric lipid shells surrounding membrane proteins in structurally heterogeneous lipid membranes. This method needs only the coordinates of the system and is independent of force fields and simulation conditions. As a proof-of-principle, we use this multiple lipid shell method to analyze the lipid disruption profiles of three simulated membrane systems: phosphatidylcholine, phosphatidylcholine/cholesterol, and beta-amyloid/phosphatidylcholine/cholesterol. We observed different atomic volume disruption mechanisms due to cholesterol and beta-amyloid. …

Xunzi And Naturalistic Ethics, Sor-Hoon Tan Mar 2015

Xunzi And Naturalistic Ethics, Sor-Hoon Tan

Research Collection School of Social Sciences

The ascendency of science in modern times makes it commonplace to accept that science presents the only true and correct image of reality. This has led to naturalization attempts in various domains, from epistemology, metaphysics, to philosophy of mind, and ethics. Naturalistic ethics may mean different things depending on what we consider natural. David Copp equates it with the empirical – emphasizing the relevance of empirical evidence to justification – while admitting that what is empirical is itself problematic.1 One might count as empirical that which can be observed by our physical senses, or more narrowly that which can be …

Lay Theories About Social Class Buffer Lower-Class Individuals Against Poor Self-Rated Health And Negative Affect, Jacinth J. X. Tan, Michael W. Kraus Mar 2015

Lay Theories About Social Class Buffer Lower-Class Individuals Against Poor Self-Rated Health And Negative Affect, Jacinth J. X. Tan, Michael W. Kraus

Research Collection School of Social Sciences

The economic conditions of one’s life can profoundly and systematically influence health outcomes over the life course. Our present research demonstrates that rejecting the notion that social class categories are biologically determined—a nonessentialist belief—buffers lower-class individuals from poor self-rated health and negative affect, whereas conceiving of social class categories as rooted in biology—an essentialist belief—does not. In Study 1, lower-class individuals self-reported poorer health than upper-class individuals when they endorsed essentialist beliefs but showed no such difference when they rejected such beliefs. Exposure to essentialist theories of social class also led lower-class individuals to report greater feelings of negative self-conscious …

Comparison Of Regular Ringer's Solution And Glucose Ringer's Solution On The Longevity Of The Hirudo Medicinalis' Retzius Cell, Nicole Arielle Peretti Mar 2015

Comparison Of Regular Ringer's Solution And Glucose Ringer's Solution On The Longevity Of The Hirudo Medicinalis' Retzius Cell, Nicole Arielle Peretti

Master's Theses

In 1882, Sydney Ringer, a professor of medicine at University College in London, experimented with the frog ventricle to better understand how each constituent of blood influences contraction. The ultimate goal was to create an artificial circulating fluid to use for the perfusion of isolated organs, in this case, a frog heart. Today, Ringer’s solution is still used in research for physiological studies requiring the survival and maintenance of specimens outside of their host bodies. One such example is the use of medicinal leech ganglia for electrophysiological measurements. In this thesis, I am comparing two Ringer’s solutions, original versus added …

Dissolved Fe And Al In The Upper 1000 M Of The Eastern Indian Ocean: A High‐Resolution Transect Along 95°E From The Antarctic Margin To The Bay Of Bengal, Maxime Grand, Christopher Measures, Mariko Hatta, William Hiscock, William Landing, Peter Morton, Clifton Buck, Pamela Barrett, Joseph Resing Mar 2015

Dissolved Fe And Al In The Upper 1000 M Of The Eastern Indian Ocean: A High‐Resolution Transect Along 95°E From The Antarctic Margin To The Bay Of Bengal, Maxime Grand, Christopher Measures, Mariko Hatta, William Hiscock, William Landing, Peter Morton, Clifton Buck, Pamela Barrett, Joseph Resing

Faculty Publications

A high‐resolution section of dissolved iron (dFe) and aluminum (dAl) was obtained along ~95°E in the upper 1000 m of the eastern Indian Ocean from the Antarctic margin (66°S) to the Bay of Bengal (18°N) during the U.S. Climate Variability and Predictability (CLIVAR) CO2 Repeat Hydrography I08S and I09N sections (February–April 2007). In the Southern Ocean, low concentrations of dAl (<1 n M) reflect the negligible dust inputs impacting the water masses subducted in the circumpolar domain. The low dAl concentrations characterizing the Southern Ocean terminate near 45°S, probably because of the advection of subtropical water masses that received dust and sedimentary inputs in their formation region. Our subsurface dFe data near the southern Kerguelen Plateau were significantly higher than historical observations in other Indian sectors of the Southern Ocean. We surmise that the offshore advection of dFe‐rich waters along the western flank of the southern Kerguelen plateau and enhanced vertical mixing could contribute to this elevated subsurface dFe inventory. Elevated subsurface particulate and dFe levels downstream of the northern Kerguelen Plateau may reflect long‐range lateral transport from the plateau's sediments and/or remineralization inputs. At the northern edge of the south Indian subtropical gyre, the deposition of Australian dust, possibly combined with the advection of dAl‐enriched waters from the Indonesian Throughflow, creates a region of elevated dAl in the upper 400 m but without a corresponding enrichment in dFe. In the northern Indian Ocean, the South Equatorial Current constitutes a remarkable biogeochemical front separating the oxygen‐rich and dFe‐poor subtropical gyre waters from the dFe‐rich and oxygen‐depleted waters of the northern Indian Ocean. By tracing the accumulation of macronutrients and dFe along the advective pathway of Indian Central Water, we show that the central waters of the northern Indian Ocean receive excess dFe in addition to that produced by remineralization inputs. The resuspension of shelf sediments and release of pore waters probably contribute to the elevated dFe and dAl levels observed below the highly stratified upper layers of the Bay of Bengal.

Dust Deposition In The Eastern Indian Ocean: The Ocean Perspective From Antarctica To The Bay Of Bengal, Maxime Grand, Christopher Measures, Mariko Hatta, William Hiscock, Clifton Buck, William Landing

Faculty Publications

Atmospheric deposition is an important but still poorly constrained source of trace micronutrients to the open ocean because of the dearth of in situ measurements of total deposition (i.e., wet + dry deposition) in remote regions. In this work, we discuss the upper ocean distribution of dissolved Fe and Al in the eastern Indian Ocean along a 95°E meridional transect spanning the Antarctic margin to the Bay of Bengal. We use the mixed layer concentration of dissolved Al in conjunction with empirical data in a simple steady state model to produce 75 estimates of total dust deposition that we compare …

Fluoxetine Prevents The Development Of Depressive-Like Behavior In A Mouse Model Of Cancer Related Fatigue, Diana M. Norden, Raymond Devine, Sabahattin Bicer, Runfeng Jing, Peter J. Reiser, Loren E. Wold, Jonathan P. Godbout, Donna O. Mccarthy

College of Nursing Faculty Research and Publications

Cancer patients frequently suffer from fatigue, a complex syndrome associated with tiredness and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, escalates during treatment, and can persist for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with decreased survival in patients with incurable disease. We have previously shown that increased pro-inflammatory cytokine expression in the brain contributes to depressive- and fatigue-like behaviors in a mouse model of CRF. Inflammatory cytokines increase the activity of indoleamine 2,3-dioxygenase (IDO) and kynurenine 3-monooxygenase (KMO), which competitively reduce serotonin synthesis. Reduced serotonin …

Synthesis Of 2-Acylphenol And Flavene Derivatives From The Ruthenium-Catalyzed Oxidative C-H Acylation Of Phenols With Aldehydes, Hanbin Lee, Chae S. Yi Mar 2015

Synthesis Of 2-Acylphenol And Flavene Derivatives From The Ruthenium-Catalyzed Oxidative C-H Acylation Of Phenols With Aldehydes, Hanbin Lee, Chae S. Yi

Chemistry Faculty Research and Publications

The cationic ruthenium hydride complex [(C6H6)(PCy3)(CO)RuH]+BF4− has been found to be an effective catalyst for the oxidative C–H coupling reaction of phenols with aldehydes to give 2-acylphenol compounds. The coupling of phenols with α,β-unsaturated aldehydes selectively gives the flavene derivatives. The catalytic method mediates direct oxidative C–H coupling of phenol and aldehyde substrates without using any metal oxidants or forming wasteful byproducts.

Judicious Use Of Communication For Inherently Parallel Optimization, Andrew W. Mcnabb Mar 2015

Judicious Use Of Communication For Inherently Parallel Optimization, Andrew W. Mcnabb

Theses and Dissertations

Function optimization---finding the minimum or maximum of a given function---is an extremely challenging problem with applications in physics, economics, machine learning, engineering, and many other fields. While optimization is an active area of research, only a portion of this work acknowledges parallel computation, which is now widely available. Today, anyone with a modest budget can buy a cluster with hundreds of cores, pay for access to a supercomputer with thousands of processors, or at least purchase a laptop with 8 cores. Thus, an algorithm that works well in serial but cannot be parallelized is needlessly inefficient in real-life computationalenvironments.We address …

Rapid Imbibition Of Water In Fractures Within Unsaturated Sedimentary Rock, Chu-Lin Cheng, E. Perfect, B. Donnelly, H. Z. Bilheux, A. S. Tremsin, L. D. Mckay, V. H. Distefano, J. C. Cai, L. J. Santodonato

School of Earth, Environmental, & Marine Sciences Faculty Publications

The spontaneous imbibition of water and other liquids into gas-filled fractures in variably-saturated porous media is important in a variety of engineering and geological contexts. However, surprisingly few studies have investigated this phenomenon. We present a theoretical framework for predicting the 1-dimensional movement of water into air-filled fractures within a porous medium based on early-time capillary dynamics and spreading over the rough surfaces of fracture faces. The theory permits estimation of sorptivity values for the matrix and fracture zone, as well as a dispersion parameter which quantifies the extent of spreading of the wetting front. Quantitative data on spontaneous imbibition …

The Loss Of Hh Responsiveness By A Non-Ciliary Gli2 Variant, Jinling Liu, Huiqing Zeng, Aimin Liu Mar 2015

The Loss Of Hh Responsiveness By A Non-Ciliary Gli2 Variant, Jinling Liu, Huiqing Zeng, Aimin Liu

Engineering Management and Systems Engineering Faculty Research & Creative Works

Hedgehog signaling is crucial for vertebrate development and physiology. Gli2, the primary effector of Hedgehog signaling, localizes to the tip of the primary cilium, but the importance of its ciliary localization remains unclear. We address the roles of Gli2 ciliary localization by replacing endogenous Gli2 with Gli2ΔCLR, a Gli2 variant not localizing to the cilium. The resulting Gli2ΔCLRKI and Gli2ΔCLRKI;Gli3 double mutants resemble Gli2-null and Gli2;Gli3 double mutants, respectively, suggesting the lack of Gli2ΔCLR activation in development. Significantly, Gli2ΔCLR cannot be activated either by pharmacochemical activation of Smo in vitro or by loss …

The Internationalization Of Agency Actions, Jason Marisam Mar 2015

The Internationalization Of Agency Actions, Jason Marisam

Fordham Law Review

    U.S. agencies routinely base their domestic regulations on international considerations, such as the benefits of coordinating American and foreign standards or the foreign policy advantages of a particular policy. I refer to this phenomenon as the internationalization of agency actions. This Article examines what the internationalization of agency actions means for agency decision-making processes, institutional design, and legal doctrine. It creates a stylized model of how agencies determine whether to coordinate their standards with foreign regulations. Among other institutional design findings, it shows that court opinions that reduce the stringency of judicial review when agencies implement internationally coordinated standards make …

Vibrational Microspectroscopy For Cancer Screening, Fiona Lyng, Ines Ramos, Ola Ibrahim, Hugh Byrne Mar 2015

Vibrational Microspectroscopy For Cancer Screening, Fiona Lyng, Ines Ramos, Ola Ibrahim, Hugh Byrne

Articles

Vibrational spectroscopy analyses vibrations within a molecule and can be used to characterise a molecular structure. Raman spectroscopy is one of the vibrational spectroscopic techniques, in which incident radiation is used to induce vibrations in the molecules of a sample, and the scattered radiation may be used to characterise the sample in a rapid and non-destructive manner. Infrared (IR) spectroscopy is a complementary vibrational spectroscopic technique based on the absorption of IR radiation by the sample. Molecules absorb specific frequencies of the incident light which are characteristic of their structure. IR and Raman spectroscopy are sensitive to subtle biochemical changes …
