In 2018, forty-five years after the high-profile abduction of Patricia Hearst by the Symbionese Liberation Army, CNN returned her captivity narrative to mass media in the documentary series The Radical Story of Patty Hearst. A year later, Netflix brought to a close the narrative of Kimmy Schmidt, the ever optimistic and resilient survivor of childhood abduction and fifteen years of captivity in a bunker. Tales of captivity have dominated the digital streaming universe in recent years even as the captivity narrative has proven to be a malleable genre: from the dark dystopia of The Handmaid’s Tale which powerfully depicts …


Association Of Total Zinc Intake With Myopia In U.S. Children And Adolescents, Niamh Burke, John Butler, Daniel Ian Flitcroft, Daniel Mccartney, James Loughman Sep 2019

Association Of Total Zinc Intake With Myopia In U.S. Children And Adolescents, Niamh Burke, John Butler, Daniel Ian Flitcroft, Daniel Mccartney, James Loughman

Articles

Significance: This present study advances our knowledge on the role of lifestyle factors in myopia (short-sightedness), specifically dietary factors. It has been suggested in previous studies that lower zinc status is associated with myopia; however, this article shows no relationship between dietary zinc intake and myopia in U.S. adolescents. Purpose: It has been suggested that low zinc levels may contribute to the development of myopia. The aim of the present study is to examine, for the first time in a Western population, the association of total dietary and supplement zinc intake with myopia. Methods: A total of 1095 children/adolescents aged …

Investigation Of The Accuracy Of Alcohol And Drug Involvement Reporting, William Nicholas Staats

Kentucky Transportation Center Research Report

Executive Summary

Researchers compared the 2013 to 2017 fatal crash data from the KSP database to the crash data from the FARS database to check the consistency and accuracy of alcohol and drug involvement reporting for drivers in the KSP database. The indications of alcohol and drug involvement in the FARS database were used as the ground truth due to the inclusion of laboratory test results confirming the presence of alcohol and/or drugs in a driver’s system. For the five-year study period, the indications for alcohol involvement were 85.8% consistent and the indications of drug involvement were 66.2% consistent between …


Everything In Its Place: A Conceptual Framework For Anti-Music, Nicole L. Carroll Sep 2019

Everything In Its Place: A Conceptual Framework For Anti-Music, Nicole L. Carroll

Sound Scripts

In this paper I describe my live performance practice utilising bespoke synthesisers and controllers. I address the conceptual approach and processes in the context of esoteric systems and give a technical description of the instruments. I situate my work in the context of Victorian Spiritualism and magic ritual. Following their precedent, I amalgamate systems and esoteric concepts to meet the goals of transformation and connecting to unknown forces, designing hybrid systems that allow me to approach a performance as an automatic mediumship process. I work primarily with NASA’s lunar orbital data, W.B. Yeats’ esoteric system detailed in A Vision (1937), …

Steroidal Alkaloid Variation In Veratrum Californicum As Determined By Modern Methods Of Analytical Analysis, Matthew W. Turner, Meagan Rossi, Vannessa Campfield, John French, Ellie Hunt, Emily Wade, Owen M. Mcdougal

Chemistry and Biochemistry Faculty Publications and Presentations

Veratrum californicum is a rich source of steroidal alkaloids, many of which have proven to be antagonists of the Hedgehog (Hh) signaling pathway that becomes aberrant in over twenty types of cancer. These alkaloids first became known in the 1950's due to their teratogenic properties, which resulted in newborn and fetal lambs developing cyclopia as a result of pregnant ewes consuming Veratrum californicum. It was discovered that the alkaloids in V. californicum were concentrated in the root and rhizome of the plant with much lower amounts of the most active alkaloid, cyclopamine, present in the aerial plant, especially in …


Trump's Angry White Women: Motherhood, Nationalism, And Abortion, Yvonne Lindgren Sep 2019

Trump's Angry White Women: Motherhood, Nationalism, And Abortion, Yvonne Lindgren

Hofstra Law Review

A majority of white women-- fifty-two percent-- voted for Donald Trump in the 2016 presidential election. White working-class women supported Trump in even greater numbers: sixty-one percent of white women without college degrees voted for Trump. This result seems remarkable considering Trump's derogatory statements about women and his staunch opposition to legal access to abortion. Why did white women, especially those most likely to need access to reproductive healthcare-- poor and working-class women-- vote heavily against their own interests to embrace a candidate who called for punishing women who access abortion? Much recent commentary has considered this question and drawn …


Revisiting Masterpiece Cakeshop - Free Speech And The First Amendment: Can Political Correctness Be Compelled, Terri R. Day Sep 2019

Revisiting Masterpiece Cakeshop - Free Speech And The First Amendment: Can Political Correctness Be Compelled, Terri R. Day

Hofstra Law Review

This Article questions whether religious objectors, who refuse to provide their services in facilitating a same-sex marriage, are discriminating on the basis of sexual orientation or refusing to adopt a politically correct, albeit legal, view of marriage. If the latter, then, compelling political correctness can have a boomerang effect, creating more LGBTQ discrimination. Given this administration's strong support for religious freedom and two new conservative justices on the Supreme Court, a legislative religious exemption in public accommodation laws may be safer for LGBTQ rights than risking a Supreme Court ruling constitutionally enshrining a religious right to discriminate.

Dermatoglyphic Measures In Relation To Depressive Symptoms Among Non-Clinical Adolescents And Young Adults, Yosefa A. Modiano Sep 2019

Dermatoglyphic Measures In Relation To Depressive Symptoms Among Non-Clinical Adolescents And Young Adults, Yosefa A. Modiano

Dissertations, Theses, and Capstone Projects

Depressive disorders are highly prevalent and can be devastating. Increasingly, depressive symptomatology is understood from a dimensional perspective such that non- or sub-clinical presentations may share a similar etiology. Depression etiology is believed to include genetic and environmental factors that may contribute to underlying vulnerability (diathesis) by way of neurodevelopment. Birth cohort studies have provided empirical evidence of the relationship between prenatal insult and later experience of adverse outcomes, including increased risk for depressive disorders. Retrospective investigation of the possible influence of prenatal disturbance on later experience of depressive symptoms has methodological limitations. Dermatoglyphic measurements offer a more methodologically viable …


Murine Genetic Variance In Sugar And Fat-Conditioned Flavor Preferences: Roles Of Dopamine, Opioid And Nmda Receptors And Nutritive Sensing, Tamar T. Kraft Sep 2019

Murine Genetic Variance In Sugar And Fat-Conditioned Flavor Preferences: Roles Of Dopamine, Opioid And Nmda Receptors And Nutritive Sensing, Tamar T. Kraft

Dissertations, Theses, and Capstone Projects

As obesity and diabetes have emerged as a severe public health crisis, understanding the mechanisms underlying the consumption of sugars and fats has become a topic of vigorous study. From a biological standpoint, genetic dispositions, neurochemical and hormonal influences, and predetermined orosensory and postingestive signals that modulate the hunger and satiety process may govern physiological aspects of the obesity puzzle. In addition to an innate appetite and attraction for simple carbohydrates and fats, learning plays an important role in modulating preferences for sugar- and fat-rich foods in rodents, including inbred mouse strains. Marked genetic variance has been observed among murine …


The Interaction Of Attention And Memory On The Reorienting Negativity, John C. Moses Sep 2019

The Interaction Of Attention And Memory On The Reorienting Negativity, John C. Moses

Dissertations, Theses, and Capstone Projects

The three-stage model of distraction asserts that when we are presented with salient but task-irrelevant information, our sensory systems first detect the distracting stimulus by way of sensory memory buffers, which is indicated electrophysiologically by the mismatch negativity (MMN). Following detection, attentional resources are involuntarily allocated towards the processing of the distraction, as represented by the P3a. Finally, attentional resources are shifted away from the distracting stimulus and returned to the task-relevant information, as indicated by the reorienting negativity (RON). A great deal of research has focused on this last step in the model, largely centering around defining the mechanisms …


Development Of Business Models For Indigenous Genetic Improvement In Small Ruminant Farms Through Reproductive Biotechnology, Sarawanee Khunmanee, Theerawat Swangchan-Uthai, Junpen Suwimonteerabutr, Pintira Thiangthientham, Sanya Supappornchai, Mongkol Techakumphu Sep 2019

Development Of Business Models For Indigenous Genetic Improvement In Small Ruminant Farms Through Reproductive Biotechnology, Sarawanee Khunmanee, Theerawat Swangchan-Uthai, Junpen Suwimonteerabutr, Pintira Thiangthientham, Sanya Supappornchai, Mongkol Techakumphu

The Thai Journal of Veterinary Medicine

This study aimed to establish a business model of reproductive biotechnology in small ruminant. Sets of questionnaires were administered to interview 115 farmers from different regions in Thailand. Data including age, educational background, farm size and type, source of replacement breeders, breeding technology, farm problems and attitude toward the technology were collected. Logistic regression analysis along with neutral network analysis was used to identify factors associated technology interest with P< 0.05. Results showed that among 115 participants, 72.2% were interested in reproductive biotechnology. In univariate logistic regression analysis, farmer’s age [OR=0.96, 95% CI (0.93,1.00)], educational background [OR=1.17, 95% CI (0.13,0.80)], production problems [OR=1.28, 95% CI (1.12,1.478)] and marketing problems [OR=1.40, 95% CI (1.18,1.67)] were independently associated with technology interest (P< 0.05). Similar to the neural network analysis, farmer’s age, overall farm problems, marketing problems, production problems and educational background were the primary factors influencing technology interest of farmers. Next, the data from 18 semi-structured interviews were interpreted to establish suggested business models of reproductive biotechnology package. This indicated that a single business model could not fit the expectation of all farmers. Thus, six business models were established and 2 models were initially implemented in 7 farms with a moderate successful rate. In conclusion, the implement ofreproductive biotechnology in small ruminant farm should be addressed to the young farmers with high education to improve the animal genetic value and sustain their livelihoods. However, the different farm managements play a key role in the success of these business models.

Nonrandom Territory Occupancy By Nesting Gyrfalcons (Falco Rusticolus), David L. Anderson, Peter J. Bente, Travis L. Booms, Leah Dunn, Christopher J.W. Mcclure

Public Policy and Administration Faculty Publications and Presentations

We know little regarding how specific aspects of habitat influence spatial variation in site occupancy by Arctic wildlife, yet this information is fundamental to effective conservation. To address this information gap, we assessed occupancy of 84 Gyrfalcon (Falco rusticolus Linnaeus, 1758) breeding territories observed annually between 2004 and 2013 in western Alaska. In line with the theory of population regulation by site dependence, we asked whether Gyrfalcons exhibited a nonrandom pattern of site selection and if heterogeneous landscape attributes correlated with observed occupancy patterns. We characterized high- and low-occupancy breeding territories as those occupied more or less often than …

Relational Liaising To Integrate Informed Learning Into The Disciplinary Classroom, Kim L. Ranger

Books and Contributions to Books

This conceptual chapter sets the stage for how librarians can support informed learning. It looks at how the intersections between informed learning, Bakhtin’s philosophy of communication, and relational leadership contribute to a model of relational liaising. The chapter provides examples of practical applications, interdisciplinary collaboration, and shared leadership which librarians and other teachers can adapt for specific arts, humanities, or social sciences disciplines. Many of the illustrations are set within communication-related curricula but also include the arts.


Introduction For Informed Learning Applications: Insights From Research And Practice, Kim L. Ranger Sep 2019

Introduction For Informed Learning Applications: Insights From Research And Practice, Kim L. Ranger

Books and Contributions to Books

Informed learning practice encompasses a range of approaches including collaboration between librarians and classroom instructors (whose primary responsibility is teaching regularly-scheduled courses) to construct connections between informed learning theory, information literacy practice, and disciplinary scholarly products to foster reflective and deep engagement with information. Informed learning differs from other approaches to information literacy in that the focus is on both the process of learning disciplinary content and the knowledge gained as a result of interacting with information (information literacy experiences) while seeking, evaluating, and citing. Reflection, transformation, and relationship are vital elements of informed learning, and scholarly communication is integrated …


Diabetes-Related Amylin Dyshomeostasis: A Contributing Factor To Cerebrovascular Pathology And Dementia, Han Ly, Florin Despa Sep 2019

Diabetes-Related Amylin Dyshomeostasis: A Contributing Factor To Cerebrovascular Pathology And Dementia, Han Ly, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

Type 2 diabetes (T2D) increases the risk for cerebrovascular disease (CVD) and dementia. The underlying molecular mechanisms remain elusive, which hampers the development of treatment or/and effective prevention strategies. Recent studies suggest that dyshomeostasis of amylin, a satiety hormone that forms pancreatic amyloid in patients with T2D, promotes accumulation of amylin in cerebral small blood vessels and interaction with Alzheimer's disease (AD) pathology. Overexpression of human amylin in rodents (rodent amylin does not form amyloid) leads to late-life onset T2D and neurologic deficits. In this Review, we discuss clinical evidence of amylin pathology in CVD and AD and identify critical …

Thwarting Repair: Gutter, Stutter, Are You My Mother?, Chase Gregory

Faculty Journal Articles

Alison Bechdel’s graphic memoir Are You My Mother? A Comic Drama (2012) presents an interesting challenge to literary critics: as an object that extensively theorizes itself, it leaves little room for interpretation beyond its surface-level claims. This article reads against the grain of Are You My Mother? ’s own analysis in order to make room for readings that resist taking the text at its word. Although Are You My Mother? proclaims loyalty to the psychoanalytic theories of Donald Winnicott, Bechdel employs the metaphor of the mirror and the formal qualities of comics to complicate the reductive assertions of her avatar’s …

Opposite Sides Of The Same Coin: Worker Classification In The New Economy, Griffin Toronjo Pivateau Sep 2019

Opposite Sides Of The Same Coin: Worker Classification In The New Economy, Griffin Toronjo Pivateau

Hofstra Labor & Employment Law Journal

Massive changes have disrupted the institution of employment. The growth of the service sector, technological advancements, and developments in the finance market have created a demand for new employment models. Employers have responded by increasingly utilizing independent contractors to fill positions traditionally held by employees.

Designating a worker as either "employee" or "independent contractor" determines the degree to which employment law applies to the worker. An independent contractor falls outside many of the benefits and protections that the law provides employees. Currently, courts, states, and administrative agencies use a confusing array of employment tests, created for different purposes and different …

Purpose and Significance: Therapeutic riding (TR) is equine-assisted riding lessons that are adapted for people with a wide variety of impairments and is often used as an adjunct to traditional therapies. Previous research has shown that TR helped to improve sensory functioning, cognition and social skills in children with Autism Spectrum Disorder (ASD) but sessions have typically been for 10-12 weeks. The purpose of this study was to investigate if social skills and sensory functioning improved after only 8 weeks of TR.

Subjects: Children were recruited from a local TR center. Participants included seven children (5M, 2F) with a diagnosis …


Water Entry Impact Dynamics Of Diving Birds, Saburel I. Sharker, Sean Holekamp, Mohammad M. Mansoor, Tadd T. Truscott Sep 2019

Water Entry Impact Dynamics Of Diving Birds, Saburel I. Sharker, Sean Holekamp, Mohammad M. Mansoor, Tadd T. Truscott

Biology Faculty Publications

Some seabirds (such as northern gannets and brown boobies) can dive from heights as high as 30 m reaching speeds of up to 24 m s−1 as they impact the water surface. The physical geometry of plunge diving birds, particularly of the beak, allows them to limit high impact forces compared to non-diving birds. Numerically simulated data for one species (northern gannet) provides some insight into the impact forces experienced during diving, however, no reliable experimental data with real bird geometries exist for comparison purposes. This study utilizes eleven 3D printed diving bird models of three types of birds: plunge-diving …
