Over-Reaction To The Calpers Focus List?, Tyler Yoder, Dean Johnson, Joseph Goebel, William A. Ogden, Srinivasan Sundaram

College of Business Publications

The California Public Employees Retirement System (CalPERS) has over $ 200 billion in assets. Over the years it has gained an activist reputation. The size of investment provides it with a strong voice and the incentive to incur monitoring costs. CalPERS nudges the management and the board to act in the best interest of the shareholders. CalPERS regularly examines its portfolio and seeks change in firms that can potentially perform better. Some firms heed to this attention while those that ignore the attention end up on the focus list. This study examines the reaction of the market to the publishing …

The Design And Implementation Of Metrics To Assess A Marine Science Environmental Education Program, Chelsea A. Werner

Open Access Theses

Environmental education, particularly marine science education, is an emerging discipline. Evaluations of existing programs are necessary and best practices must continue to be developed. Students from Miami Science Museum’s Upward Bound Math and Science program participated in a new series of environmentally focused activities called the Eco-Ambassadors program. This program consisted of seven activities, including kayaking, habitat restoration, and a film workshop. An assessment of the Eco-Ambassadors program, consisting of a pre-survey and a post-survey, was conducted for this study in order to determine the success of the program. The surveys assessed student’s experiences, interests, knowledge, and attitudes. No statistically …

A New Approach To Light-Weight Ablators Analysis: From Micro-Tomography Measurements To Statistical Analysis And Modeling, Nagi N. Mansour, Francesco Panerai, Alexandre Martin, Dilworth Y. Parkinson, Alastair A. Macdowell, Abdelmoula Haboub, Timothy A. Sandstrom, Tony Fast, Gerard L. Vignoles, Jean Lachaud

Mechanical Engineering Faculty Publications

The morphology characteristics and ablation behavior of a highly porous carbon fiber preform are studied using a combined experimental/numerical approach. Morphological characterization of the three-dimensional structure of the material is performed by hard X-rays synchrotron micro-tomography at the Advanced Light Source of Lawrence Berkeley National Laboratory. The resulting micro-tomography voxels are used to compute geometrical properties of the carbon preform, like porosity, specific surface area and tortuosity, that are otherwise indirectly measured through experimental techniques. The reconstructed volumes are used to build a computational grid for numerical simulations of the fibers' ablation. By modeling the diffusion of oxygen through the …

Flow-Tube Oxidation Experiments On The Carbon Preform Of Pica, Francesco Panerai, Alexandre Martin, Nagi N. Mansour, Steven A. Sepka, Jean Lachaud

Mechanical Engineering Faculty Publications

Oxidation experiments on the carbon preform of a phenolic-impregnated carbon ablator were performed in the NASA Ames ow-tube reactor facility, at temperatures between 700 and 1300 K, under dry air gas at pressures between 103 and 104 Pa. Mass loss, volumetric recession and density changes were measured at different test conditions. An analysis of the diffusion/reaction competition within the porous material, based on the Thiele number, allowed us to identify low temperature and low pressure conditions to be dominated by in-depth volume oxidation. Experiments above 1000 K were found at transition conditions, where diffusion and reaction occur at similar scales. …

“Poor Forsaken Colored Girls:” Rebecca Latimer Felton, White Supremacy, And Prison Reform, 1865-1900, Amanda Helms

College of Liberal Arts & Social Sciences Theses and Dissertations

The main argument of this thesis is that The Women's Prison Reform Movement, from 1865-1900, was constructed around both gendered and racial ideologies that linked so-called "proper" womanhood to whiteness and marked black women as subhuman, impure, and unable to be reformed, and that this served to exclude black women from the designation of 'woman' and therefore from the Women's Prison Reform Movement. I also argue that overt acts of racism, as well as systematic white supremacy, were foundational in the movement from the beginning. In a brief examination of the early prison and convict lease system in the Southern …

Addressing The Intersection Of Sexual Identity And Sexual Behavior For Women Who Have Sex With Women: Understanding Risk And Exploring Options, Joan Pinnell

College of Liberal Arts & Social Sciences Theses and Dissertations

Variable inconsistencies and conflicting theories on female sexual orientation compromise women’s sexual health research. Subsequently, health risks associated with female-to-female sex play are largely unknown and providers continue framing services for sexual identities. The study’s focus was first, to establish whether discordance between sexual behavior and identity among women who have sex with women (WSW) correlates with risky sexual behaviors and then, to explore healthcare providers’ and practitioners’ methods for addressing the intersection of patients’ sexual identity and reported behaviors. After WSW sexual health-related response outcomes from a NYC Community Health Survey sample were assessed, practitioners from three providers were …

Subtelomeric Hotspots Of Aberrant 5-Hydroxymethylcytosine-Mediated Epigenetic Modifications During Reprogramming To Pluripotency, Stormy J. Chamberlain, I-Ping Chen

UCHC Articles - Research

Mammalian somatic cells can be directly reprogrammed into induced pluripotent stem cells (iPSCs) by introducing defined sets of transcription factors. Somatic cell reprogramming involves epigenomic reconfiguration, conferring iPSCs with characteristics similar to embryonic stem cells (ESCs). Human ES cells contain 5-hydroxymethylcytosine (5hmC), which is generated through the oxidation of 5-methylcytosine by the TET enzyme family. Here we show that 5hmC levels increase significantly during reprogramming to human iPSCs mainly due to TET1 activation, and this hydroxymethylation change is critical for optimal epigenetic reprogramming, but does not compromise primed pluripotency. Compared with hES cells, we find iPS cells tend to form …

Preharvest Quarantine Treatments Of Chlorantraniliprole, Clothianidin, And Imidacloprid-Based Insecticides For Control Of Japanese Beetle (Coleoptera: Scarabaeidae) And Other Scarab Larvae In The Root Zone Of Field-Grown Nursery Trees, Jason B. Oliver, Christopher M. Ranger, Michael E. Reding, James J. Moyseenko, Nadeer N. Youssef, Alicia M. Bray

Agricultural and Environmental Sciences Faculty Research

Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), is an important quarantine pest of nurseries. Nursery plant movement from P. japonica-infested regions is regulated by the U.S. Domestic Japanese Beetle Harmonization Plan (DJHP), which classifies states by risk categories. Treatments for category 2 states include preharvest soil surface treatment of nursery plants grown in field soil using Discus SC, Marathon (1G or 60 WP), or Flagship (0.22G or 25 WG). In this study, Discus, Marathon 60 WP, or Flagship 0.22G DJHP standards were compared with labeled rates of non–DJHP-approved insecticides, including neonicotinoids clothianidin (Arena 50WDG), generic imidacloprid (Quali-Pro Imidacloprid 2 F …

Tools For Assessing Climate Impacts On Fish And Wildlife, Chad B. Wilsey, Joshua J. Lawler, Edwin P. Maurer, Donald Mckenzie, Patricia A. Townsend, Richard Gwozdz, James A. Freund, Keala Hagmann, Karen M. Hutten

Civil, Environmental and Sustainable Engineering

Climate change is already affecting many fish and wildlife populations. Managing these populations requires an understanding of the nature, magnitude, and distribution of current and future climate impacts. Scientists and managers have at their disposal a wide array of models for projecting climate impacts that can be used to build such an understanding. Here, we provide a broad overview of the types of models available for forecasting the effects of climate change on key processes that affect fish and wildlife habitat (hydrology, fire, and vegetation), as well as on individual species distributions and populations. We present a framework for how …

Top-Down Regulation Of Litter Invertebrates By A Terrestrial Salamander, Bernard Michael Walton

Biological, Geological, and Environmental Faculty Publications

Terrestrial plethodontid salamanders are abundant predators within the forest floor litter of eastern North America, and are hypothesized to regulate soil and litter invertebrate density and species composition. I tested this hypothesis during a 6-yr study of the effects of the Eastern Red-backed Salamander (Plethodon cinereus) on the invertebrate community of a forest site in northeast Ohio. Salamander surface density, invertebrate abundance, and community composition were monitored within 30 open, circular plots. Variation in plot occupancy by P. cinereus was achieved by supplying plots with differing amounts of artificial cover (0, 1, or 4 ceramic tiles) that served …

The Emotions Of Change: A Case Study, Kerri S. Kearny, Kayla D. Siegman

Organization Management Journal

The purpose of this article is to report on a specific team intervention, a rapidly constructed response to a request for help with a situation that was believed by the chief executive officer (CEO) to have reached a crisis stage. The effort was, of necessity, “on the fly,” and the roles of consultant, participant, researcher, and collaborator were blurred and evolving as answers to the immediate problem were sought. This article presents and reflects on four tools used as a part of the intensive work with the emotional aspects of the team’s experiences of revolutionary organizational change. In extended follow-up …

Idiopathic Inflammatory Myopathies: Pathogenic Mechanisms Of Muscle Weakness, Sree Rayavarapu, William Coley, Travis B. Kinder, Kanneboyina Nagaraju

Genomics and Precision Medicine Faculty Publications

Idiopathic inflammatory myopathies (IIMs) are a heterogenous group of complex muscle diseases of unknown etiology. These diseases are characterized by progressive muscle weakness and damage, together with involvement of other organ systems. It is generally believed that the autoimmune response (autoreactive lymphocytes and autoantibodies) to skeletal muscle-derived antigens is responsible for the muscle fiber damage and muscle weakness in this group of disorders. Therefore, most of the current therapeutic strategies are directed at either suppressing or modifying immune cell activity. Recent studies have indicated that the underlying mechanisms that mediate muscle damage and dysfunction are multiple and complex. Emerging evidence …

Comparing Effects Of Insecticides On Two Green Lacewings Species, Chrysoperla Johnsoni And Chrysoperla Carnea (Neuroptera: Chrysopidae), K. G. Amarasekare, P. W. Shearer

Agricultural and Environmental Sciences Faculty Research

This study compared lethal and sublethal effects of five insecticides, chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin, on adult and second instars of two green lacewing species, Chrysoperla carnea (Stephens) and Chrysoperla johnsoni Henry, Wells and Pupedis (Neuroptera: Chrysopidae) in the laboratory. Formulated pesticides were tested using concentrations equivalent to the high label rate dissolved in 378.5 liters of water. Novaluron and lambda-cyhalothrin were toxic to larvae and no treated larvae survived to the adult stage. Larva to adult survival was reduced in chlorantraniliprole, cyantraniliprole, and spinetoram treatments. Larva to adult developmental time and sex ratio were not different among the …

Diarrhea As A Risk Factor For Acute Lower Respiratory Tract Infections Among Young Children In Low Income Settings, Christa L. Fischer Walker, Jamie Perin, Joanne D. Katz, James M. Tielsch, Robert Black

Global Health Faculty Publications

Background

Diarrhea and acute lower respiratory tract infections (ALRI) are leading causes of morbidity and mortality among children under 5 years of age. We sought to quantify the correlation of diarrhea and respiratory infections within an individual child and to determine if infection with one illness increases the risk of infection with the other during the same time period.

Methods

We quantified the likelihood of an ALRI and a diarrhea episode occurring during the same week compared to the likelihood of each occurring independently in two cohorts of children under 3 years of age using a bivariate probit regression model. …

Response Of Nitrous Oxide Flux To Addition Of Anecic Earthworms To An Agricultural Field, José A. Amador, Edward J. Avizinis

Natural Resources Science Faculty Publications

The burrowing and feeding activities of earthworms may have a strong effect on the flux of N₂O from agricultural soils. As such, shifts to agricultural management practices that increase the number of earthworms require an understanding of the role of earthworms in N₂O dynamics. We conducted a field experiment to examine the effects of addition of anecic earthworms (Lumbricus terrestris) on N₂O flux in a field previously planted with corn (Zea mays) in southern Rhode Island, USA. Plots were amended with (¹⁵NH₄)₂SO₄ and …

Fuel Treatments And Fire Severity: A Meta-Analysis, Erik J. Martinson, Philip N. Omi

Joint Fire Science Program Synthesis Reports

We employed meta-analysis and information theory to synthesize findings reported in the literature on the effects of fuel treatments on subsequent fire intensity and severity. Data were compiled from 19 publications that reported observed fire responses from 62 treated versus untreated contrasts. Effect sizes varied widely and the most informative grouping of studies distinguished three vegetation types and three types of fuel treatment. The resultant meta-analytic model is highly significant (p < 0.001) and explains 78% of the variability in reported observations of fuel treatment effectiveness. Our synthesis highlights several considerations that both support and inform the current fuels management paradigm.
