These climate change impacts are especially strong within the California coastal zone, which falls under the jurisdiction of the California Coastal Commission. The Commission has a history of rigorous environmental protection and is committed to protecting California’s coast through proactive planning and regulation, however they will need to initiate coastal policies with ambitious targets to facilitate effective climate change adaptation and mitigation. This study analyzed existing California climate policies and Coastal Commission policies to identify …

Measuring Cocoa Agricultural Productivity: A Spatio-Temporal Econometric Approach, Yurlady Chaverra-Palacios

Master's Theses

A significant increase of 50.5 percent in the national production of cocoa was registered between 2011 and 2015 in Colombia. Nevertheless, 5,890 tons were imported in 2015 to supply domestic demand. Unlike other crops, the production of cocoa has made a significant contribution to the income of approximately 38,000 families of which 90 percent are small farm-producers with very little capital. Facilitating credit for investment is one of the main strategies of the national government to increase cocoa productivity. Correspondingly, the impact of the credit for investment on the cocoa agricultural productivity and if those investments have a spillover effect …

Frogs Hiding In Plain Sight: Phylogenetic Systematics Of Myanmar’S Occidozyga Species Complex, And The Identification Of A Novel Species, Allison Bogisich

Master's Theses

Different species can be difficult to distinguish from one another when they are morphologically similar. Such cryptic species are the reason many anuran species go undetected. For this study, the taxonomic identity of the Occidozyga complex across Myanmar was investigated. An integrated approach was used combining molecular, morphological and phylogeographic data to better assess its taxonomy. Results indicate the presence of three new candidate species within Occidozyga, and three evolutionarily significant unit (ESU) lineages. Two mitochondrial gene fragments (16S, COI) and one nuclear gene fragment (Rhodopsin) were examined from DNA isolated from forty-seven preserved specimens from the California Academy …

Eugenics In Education Policy And The Impact On African American Students, Ruth Jones

Master's Theses

Eugenics was defined as a science which used selective breeding as a mechanism to increase desirable traits in a population while restricting and eliminating undesirable traits. Eugenicists fell out of favor in the United States after the fall of Nazi Germany. Yet, eugenic ideas continued to prevail as they heavily influenced medical, social, and academic systems in the U.S. The country’s education system still carries the legacy of eugenicists who helped to build it. The purpose of this qualitative study is to identify eugenic ideas in federal, district and local school policy and determine their connection to the very local …

Breaking The Chains: Reversing The School-To-Prison Pipeline Through The Academic Experiences Of Formerly Incarcerated Black Males, Folasade Ogunbanwo

Master's Theses

This case study explores the academic experiences of formerly incarcerated Black males. The goal of the case study is to inform policymakers and critical race scholars who take interest in the prison-to-school pipeline and ultimately dismantle the school-to-prison pipeline. The historical impact of slavery has manifested into this vicious pipeline and the overrepresentation of Black males in the prison industrial complex. This case study is to demonstrate how the net is casted on those affected by the incarceration system and that break the cycle for themselves by pursuing an education to create an upward academic trajectory.

Bilinguals’ Double Phonemic Boundary: Not One Of Normal Nature, Gianna Duncan

Master's Theses

The present investigation reports the conditions that propel bilinguals’ double phonemic boundary, a phenomenon where bilinguals’ perception of speech sounds is affected by the linguistic context in which they are immersed, and theories that support bilinguals’ phonetic category structures while taking into consideration different auditory biases that could influence the double phonemic boundary such as contrast-effects, range-effects, and resource allocation. Thirty-three right-handed participants performed a Go/No-Go-Task. The sample consisted of 16 English monolinguals and 17 Spanish-English bilinguals. Participants were instructed to press a response button, using the right or left hand, when detecting 3 target sounds embedded in 6 background …

The Temperature-Dependent Mechanics Of Human Articular Cartilage Under Large-Strain Shear, Lauren Marshall

Master's Theses

Articular cartilage is a soft tissue that facilitates joint movement and protects bone contact surfaces. Human articular cartilage sees a range of temperatures in vivodepending on external thermal conditions. Researchers recently demonstrated that cartilage dissipates energy during physiological loading to elevate the temperature to enhance cell viability. Despite these important insights, researchers often consider the knee isothermal, thus the large deformation mechanical response under transient thermal conditions remains largely unknown. We aimed to quantify the mechanical responses at 24°C, 40°C, 70°C, and 24°C repeated, and apply our data to determine whether the mechanical responses of cartilage vary within the …

The Effect Of Guilt Free Claims On Restrained And Non-Restrained Eaters' Purchase Intention, Perception Of Product Healthfulness, And Amount Willing To Pay For A Novel Product, Alexis Ludwig

Master's Theses

Products with health-related claims that are perceived to be tasty are more likely to be purchase by consumers than products without a claim. Restrained eaters rely more on external cues such as food packaging rather than internal cues such as hunger signals in a way to control their caloric intake.^1,2 Restrained eaters may be more susceptible to marketing and food claims compared to non-restrained eaters. We propose a guilt free message will affect perception of healthfulness. We also propose a guilt free message and eating restraint will affect purchasing decisions. Lastly, perception of healthfulness and valuing nutritious products mediates …

Regular screening for psychoactive substance misuse in primary care and other health care settings enables earlier identification and management of substance misuse; however, wide-scale implementation of Screening, Brief Intervention and Referral to Treatment (SBIRT) services is lagging. The early exposure of health professional students to simulated interprofessional SBIRT education is one solution to address barriers in the uptake of service delivery methods in health care settings. Methods. The feasibility of a newly-developed SBIRT simulation curriculum was tested with 35 interprofessional Urban Service Track Scholars during two separate training events in April and November of 2018. Results. The evaluation …

1-Norm Support Vector Machine On Single-Trial Eeg And Ecg Data To Identify Neural Oscillatory Features In The Ketamine Model For Schizophrenia, Xiao Yang

Master's Theses

Ketamine provides a useful model for studying the physiopathology of schizophrenia as it induces and exacerbates schizophrenic symptoms in healthy individuals and patients, respectively. However, it remains unclear how ketamine affects neural oscillations across frequency bands and the extent to which changes in cortical firing are independent from ketamine’s cardiovascular effects. The present study used 1-norm support vector machine (SVM) as a classification approach to determine sources of psychophysiological signal, considering both EEG and ECG, characterizing primary effects of ketamine administration. EEG and ECG recordings of 11 participants were collected before (saline) and after the ketamine (0.5 mg/kg) intravenous infusion …

The Role Of Akap18 And Protein Phosphatase Inhibitor-1 In The Heart: Defining Their Binding Domain, Shania Aponte Paris

Master's Theses

Cardiovascular disease remains the number one cause of mortality worlwide. Heart failure occurs when the heart does not meet the body’s demand. Although significant medical advances have been made, 50% of heart failure patients still die within five years of prognosis, suggesting the need for more research. Alterations of inhibitor-1 (I-1) levels and activity have been associated with heart failure. I-1 PKA-mediated phosphorylation activates its inhibitory activity against PP1, which leads to calcium re-uptake into the sarcoplasmic reticulum (SR). Calcium mishandling plays an important role in cardiac diseases, such as heart failure. Since I-1 is at the top of this …

More Than Just A Myth: How Shapeshifter Rhetoric Relates To Esl Students 2019, Amber Kent

Master's Theses

The academic analysis surrounding the shapeshifter, or shapeshifter mythologies has, so far, been related to modern issues of violence, militarization, feminism, gender studies, or studies simply focusing on the compilation of shapeshifter myths themselves. This essay will map out the current discussion surrounding shapeshifter mythology to illustrate that it has often fallen into two forms of analysis: that of an anthropological or sociological analysis, where shapeshifter myths were analyzed as a method for understanding different cultures and their development, and that of a poststructural analysis, where shapeshifter myths are analyzed as a means of deconstructing binaries such as good/bad and …

“Flowing Along The Wall”: Anarcha-Feminist Bioethics And Resistance In Octavia E. Butler’S Dawn 2019., Theresa Mendez

Master's Theses

Science fiction (sf) texts conversant with the temporal play between past, present, and future push readers to imagine the extremes of human and environmental existence, interaction, and potential. Simultaneously, despite the sf genre’s tendency to traffic in extremes, these texts provoke readers to consider the ways in which these imagined worlds are grounded in history as well as in the contemporary social moment. As Donna Haraway has argued, “the boundary between science fiction and social reality is an optical illusion” (306). This illusory boundary must continue to be traversed in order to consider how sf literatures, particularly those which imagine …

Forensic Characterization And Discrimination Of Manila Envelopes, María Isabel Sánchez Melo

Master's Theses

Envelopes can be found at crime scenes when ransom, threat letters or potentially harmful substances are sent to victims. Therefore, they are important probative items of evidence analyzed by forensic document examiners. Manila envelopes are commonly used in the United States to transport or send documents as they are made of thick and durable paper. Although there are many studies on the forensic analysis of office paper and paper-based banknotes, and only a few on white envelopes, there does not exist previously published research on the physical or chemical characterization of manila envelopes. The goal of this research was to …

A Machine Learning Technology For Rapid Detection Of Carbon Nanotubes/Dna Hybridization In Biosensor Healthcare Applications, Steven K. Ang

Master's Theses

In molecular biology, the term “DNA hybridization” generally refers to the process of forming a double stranded nucleic acid from joining two complementary strands of DNA. The degree of genetic similarity of the DNA resulting from hybridization can be detected ei ther by using the chemical characteristics of DNA samples or by utilizing reliable biosensors which transform the chemical characteristics into a source of electrical measurements. In past research about such sensors, known as DNA Hybridization Detection Systems, the thermal and electrical characteristics of carbon nanotubes are utilized to detect whether hybridization takes place or not. However, human interpretation of …

Characterizing Vegetative Communities Across The Salt Marsh To Upland Ecotone In Connecticut: Indications Of Tidal Inundation Stress In The High Marsh, Matthew J. Ormrod

Master's Theses

The viability of Connecticut’s future salt marshes remains uncertain as pressure from multiple anthropogenic stressors and accelerated relative sea level rise continue to undermine the dynamic ecogeomorphic mechanisms that allow these landscapes to persist in times of environmental change. Observed rates of relative sea level rise in the Long Island Sound estuary appear to be accelerating since recording began in the early 1930s. Furthermore, as much as 90% of the land parcels expected to undergo habitat change as marine ecosystems migrate landward are privately owned and managed. This finding suggests that, in addition to these intrinsic ecogeomorphic feedbacks that make …

Dynamic Shifting Of Virtual Network Topologies For Network Attack Prevention, Lenoy Avidan

Master's Theses

Computer networks were not designed with security in mind, making research into the subject of network security vital. Virtual Networks are similar to computer networks, except the components of a Virtual Network are in software rather than hardware. With the constant threat of attacks on networks, security is always a big concern, and Virtual Networks are no different. Virtual Networks have many potential attack vectors similar to physical networks, making research into Virtual Network security of great importance. Virtual Networks, since they are composed of virtualized network components, have the ability to dynamically change topologies. In this paper, we explore …

Ac Direct Drive Led Lighting Using Low Cost Analog Components, Miles Head

Master's Theses

This project explores the rapidly expanding area of AC direct drive for LED lighting. AC LED driving does not use typical DC-DC converter-based driving but uses semiconductor switches and a linear regulator to activate a number of LEDs proportional to the input voltage at any given time. This allows bulky, expensive magnetics to be eliminated from the system. The goal of this project was to design a scaled-down physical AC LED direct drive system to validate the conclusions of methods for improving efficiency from a previous investigation that found minimizing voltage across the linear regulating MOSFET led to higher efficiency …

Mapping Sex Offenders And Treatment Centers In Relation To Social Disorganization, Amber Amin

Master's Theses

Research shows that the clustering of Registered Sex Offenders (RSOs) is connected to social disorganization. Residential patterns disrupt the reintegration of the RSO population. Utilizing data from Queens and the Bronx, NYC, this study examines RSO clustering in the two boroughs and explores the proximity of community resources to RSO addresses that may assist reintegration. Using data from the New York Megan’s Law and census data for Queens and Bronx Counties, maps were created to study the residential patterns of RSOs. The results show clustering of RSOs in areas with variables pertaining to high social disorganization and a lack of …

Macrobenthos Responses To Dam Removal And Habitat Restoration In The West River, Connecticut, Robert W. Sheridan
