Adoptive Parenthood: an Exploratory Study of the Influence of Pre-adoption Communication Satisfaction on Post-adoption Family Adjustment and Coping

Description: There are over a million adopted children in the United States, which makes up over 2% of the population. in spite of the fact that the majority of children are adopted into loving and caring homes, early life trauma puts them at higher risk for developing behavioral and emotional problems than non-adopted children. Due to these issues, many adoptive parents encounter post-adoption stress. This stress is often linked to minimal education regarding short- and long-term challenges associated w… more

“Almost Astronauts”: Short Stories

Description: In this collection of short stories, I abduct experiences from my own life and take them on an imaginative journey. I experiment with elements of structure and point of view, often incorporating the magical or surreal to amplify the narrator’s internal landscape. As demonstrated in the title story, “Almost Astronauts,” these stories all deal with a sudden and sometimes destructive shift in the narrator’s perspective.

Alterations in Fatty Acid Amide Hydrolase (Faah) Transcript Levels and Activity Lead to Changes in the Abiotic Stress Susceptibility of Arabidopsis Thaliana

Description: N-Acylethanolamines (NAEs) are a class of bioactive lipids, and FAAH is one of the enzymes responsible for degrading NAEs in both plants and animals. in plants, FAAH appears to be closely associated with ABA, a phytohormone which has long been associated with plant stress responses, since the overexpression of FAAH in Arabidopsis results in ABA hypersensitivity. Therefore, it is reasonable to speculate that alterations in FAAH transcript levels will result in altered stress responses in plant… more

Alternative Complementation in Partially Schematic Constructions: a Quantitative Corpus-based Examination of COME to V2 and GET to V2

Description: This paper examines two English polyverbal constructions, COME to V2 and GET to V2, as exemplified in Examples 1 and 2, respectively. (1) the senator came to know thousands of his constituents (2) Little Johnny got to eat ice cream after every little league game. Previous studies considered these types of constructions (though come and get as used here have not been sufficiently studied) as belonging to a special class of complement constructions, in which the infinitive is regarded as instanti… more

The Argei: Sex, War, and Crucifixion in Rome and the Ancient Near East

Description: The purpose of the Roman Argei ceremony, during which the Vestal Virgins harvested made and paraded rush puppets only to throw them into the Tiber, is widely debated. Modern historians supply three main reasons for the purpose of the Argei: an agrarian act, a scapegoat, and finally as an offering averting deceased spirits or Lares. I suggest that the ceremony also related to war and the spectacle of displaying war casualties. I compare the ancient Near East and Rome and connect the element of … more

Baseband Noise Suppression in Ofdm Using Kalman Filter

Description: As the technology is advances the reduced size of hardware gives rise to an additive 1/f baseband noise. This additive 1/f noise is a system noise generated due to miniaturization of hardware and affects the lower frequencies. Though 1/f noise does not show much effect in wide band channels because of its nature to affect only certain frequencies, 1/f noise becomes a prominent in OFDM communication systems where narrow band channels are used. in this thesis, I study the effects of 1/f noise on … more

Bearing Strength of Cold Formed Steel Bolted Connections in Trusses

Description: The existing design provision in North American Specification for Cold- Formed Steel Structural Member (AISI S100) for the bearing strength of bolted connections were developed from tests on bolted connected sheets which were restrained by bolt nut and head with or without washers. However, in the cold-formed assemblies, particularly in trusses, the single bolt goes through both sides of the connected sections, making the connected sheets on each side unrestrained. the warping of the unrestrain… more

Charlotte Perkins Gilman: Naturalist Playwright

Description: This study explores Charlotte Perkins Gilman’s use of the dramatic form to challenge Herbert Spencer’s social Darwinism by offering feminist adaptations of Darwin’s theories of natural and sexual selection. As she does in her career-defining manifesto, Women & Economics (1898), Gilman in her lesser-known plays deploys her own brand of reform Darwinism to serve the feminist cause. Despite her absence in histories of modern drama, Gilman actively participated in the establishment and development … more

Childhood Bereavement and Parents’ Relationship With Children

Description: It has long been recognized that childhood bereavement is a risk factor for depression in adulthood. Research also has consistently demonstrated that parental depression is linked to poor parent-child relationship quality. The current study examined whether bereavement in childhood increases likelihood of current depressive symptoms among parents and explored whether this vulnerability in the parent then alters the quality of the parent-child relationship. Archival data for a sample of 86 famil… more

Continuity of Caste: Free People of Color in the Vieux Carré of New Orleans, 1804-1820

Description: Because of its trademark racial diversity, historians have often presented New Orleans as a place transformed by incorporation into the American South following 1804. Assertions that a comparatively relaxed, racially ambiguous Spanish slaveholding regime was converted into a two-caste system of dedicated racial segregation by the advent of American assumption have been posited by scholars like Frank Tannenbaum, Gwendolyn Midlo Hall, and a host of others. Citing dependence on patronage, concubin… more

The Development of Anti-submarine Warfare in the Mediterranean: the American Contribution and the Bombardment of Durazzo

Description: The Entente powers began World War I without any formal anti-submarine countermeasures. However, the Entente developed countermeasures through trial and error over time. Success was moderate until America joined the war. with America came the arrival of subchasers to the Mediterranean Theater of Operations. This highly specialized vessel helped turn the tide against U-boats. a true counter to the U-boat threat in the Mediterranean did not come until October 2, 1918 with the bombardment of Duraz… more

Effect of Resistance Training on Cytokines in Hiv+ Men with Chemical Dependence

Description: Human immunodeficiency virus (HIV) and substance abuse (drug and/or alcohol) independently impair the immune system; importantly, the combination of HIV infection and substance abuse might produce more than an additive effect on this system. Tumor necrosis factor-alpha (TNF-?) and Interferon gamma (IFN?) are pro-inflammatory cytokines involved in differentiation of Th0 cells into Th1 cells. Interleukin 4 (IL-4) and Interleukin 10 (IL-10) are anti-inflammatory cytokine involved in differentiatio… more

Effects of Layer Double Hydroxide Nanoclays on the Toxicity of Copper to Daphnia Magna

Description: Nanoparticles may affect secondary pollutants such as copper. Layer Double Hydroxides (LDH) are synthetically produced nanoparticles that adsorb copper via cation exchange. Pretreatment of copper test solutions with LDH nanoparticles followed by filtration removal of LDH nanoparticles demonstrated the smallest LDH aggregates removed the most copper toxicity. This was due to increased surface area for cation exchange relative to larger particle aggregates. Co-exposure tests of copper chlorid… more

The Effects of Textual Fluency on the Rate of Acquisition and Application of Intraverbal Relations

Description: Intraverbal behavior governs core elements of academic and intellectual behavior. These intraverbal relations can be explicitly taught when an individual is prompted to provide an appropriate response with pictures, text, or other stimuli following a verbal stimulus. It is possible that a focus on fluency of the target repertoires may lead to more conclusive data. the current study assessed the effects of precision teaching based instruction for component textual repertoires on the acquisition … more
