A Job Embeddedness Comparison Of Professors Based On Employment Status And Type, Jeremy Todd Bowser

Doctoral Dissertations and Projects

The purpose of this study was to explore the possibility of difference in the job embeddedness attitudes of full-time and part-time professors, and possible differences in job embeddedness attitudes between professors at community colleges and state universities. This research project focused on Criminology and Criminal Justice departments. The dependent variables were on-the-job and off-the-job embeddedness, and the independent variables were school type and employment status. The timely study was based on the recent trend toward hiring adjunct professors in lieu of tenured professors at community colleges and universities. The literature review identified a lacuna in the embeddedness literature within the …

Novice Elementary Teachers’ Experiences With Preparedness To Teach Mathematics: A Phenomenological Study, Ashleigh Rose Chaves

Doctoral Dissertations and Projects

The purpose of this transcendental phenomenological study was to describe novice elementary teachers’ experiences with preparedness to teach mathematics in a large school district in southeastern Massachusetts. In defining the novice elementary teachers’ experiences, I looked at the participants’ self-efficacy through the lens of Bandura’s self-efficacy theory. Self-efficacy was defined as how confident the novice teachers were in regard to their ability to teach mathematics. The focus of this study was how adequately prepared the teachers felt teaching elementary mathematics but also investigated how the teachers felt about their readiness to address the challenges students experience in mathematics.

How Relationship Status And Sociosexual Orientation Influence The Link Between Facial Attractiveness And Visual Attention, Aleksandra Mitrovic, Juergen Goller, Pablo Tinio, Helmut Leder

Department of Educational Foundations Scholarship and Creative Works

Facial attractiveness captures and binds visual attention, thus affecting visual exploration of our environment. It is often argued that this effect on attention has evolutionary functions related to mating. Although plausible, such perspectives have been challenged by recent behavioral and eye-tracking studies, which have shown that the effect on attention is moderated by various sex- and goal-related variables such as sexual orientation. In the present study, we examined how relationship status and sociosexual orientation moderate the link between attractiveness and visual attention. We hypothesized that attractiveness leads to longer looks and that being single as well as being more sociosexually …

Impact Of Nutrition On Inflammation, Tauopathy, And Behavioral Outcomes From Chronic Traumatic Encephalopathy, Jin Yu, Hong Zhu, Saeid Taheri, William Mondy, Stephen Perry, Mark S. Kindy

Pharmacy Faculty Publications

Background: Repetitive mild traumatic brain injuries (rmTBI) are associated with cognitive deficits, inflammation, and stress-related events. We tested the effect of nutrient intake on the impact of rmTBI in an animal model of chronic traumatic encephalopathy (CTE) to study the pathophysiological mechanisms underlying this model. We used a between group design rmTBI closed head injuries in mice, compared to a control and nutrient-treated groups.

Methods: Our model allows for controlled, repetitive closed head impacts to mice. Briefly, 24-week-old mice were divided into five groups: control, rmTBI, and rmTBI with nutrients (2% of NF-216, NF-316 and NF-416). rmTBI mice received four …

The Iranian Metaphysicals, Elise K. Burton

International Dialogue

Anthropologist Alireza Doostdar’s first book, The Iranian Metaphysicals, is a well-written and theoretically sophisticated contribution to scholarship on modern Iranian history and society. Combining vividly portrayed ethnography with archival research and textual analysis, he offers an unprecedented account of Iranians’ experiences with and beliefs about the supernatural. The term ‘metaphysical’ emerges directly from his Iranian interlocutors, who use the Persian equivalents metafiziki or mavara’i to describe paranormal practices and phenomena ranging from sorcery and traditional occult sciences, to spirit possession and séances, to clairvoyance and teleportation. Although many elite Iranians, secularist and orthodox Shi‘i alike, have condemned interest in the …

Soil-Plant Interface, Carbon Sequestration And The Eco Physiological Growth Of Salsola Imbricata And Zygophyllum Mandaville Using Locally Grown Rhizosphere And Endophytic Bacteria, Nour Elhouda Debouza

Civil and Environmental Theses

Salsola imbricata and Zygophyllum Mandeville are halophytic plants available widely in the UAE. These two species have important environmental services such as sand dune fixation, which will potentially improve plant cover and help tackle the problem of desertification. The species were selected due to their availability and role in the desert environment of the UAE. Plants are also constantly involved in interactions with a wide range of bacteria in the soil. These plant-associated bacteria colonize the rhizosphere (rhizobacteria), and the internal plant tissues (bacterial endophytes). Endophytic bacteria are those capable of colonizing live internal plant tissues which can be isolated …

Biological Activity Of A Tertiary Amine Plant Growth Regulator, Bmve, In Arabidopsis Thaliana And Wheat (Triticum Aestivum), Jaspinder Singh

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Plant growth regulators are synthetic compounds that influence plant growth and development and can increase growth, yield, and nutritive value of food crops. Research in the past has shown that a class of plant growth regulators known collectively as substituted tertiary amines have the potential to increase crop productivity, photosynthetic efficiency, and overall plant vigor. However, earlier efficacy studies that involved spraying plants were sometimes inconsistent or showed only minimal benefits. A new delivery method involving seed application of tertiary amines before sowing has shown promise in field trials for multiple crop species (US patent 9464283) (Yokoyama, Chan, Oyama, & …

Inferentialism, Title Vii, And Legal Concepts, Lee Farnsworth

University of Chicago Law Review

We are all textualists now, or so it has been claimed. But textualism, the practice of interpreting statutes solely by reference to their words, is often associated with conservative judicial outcomes. This is especially true when a focus on statutory text is combined with the belief that the meanings of words are fixed. This combination creates a sort of textualist originalism, in which judges interpret statutes in accordance with what the words of a statute meant to the relevant linguistic community at the time of a statute’s enactment.

In reaction to this conservative interpretive method, rejecting textualism but keeping an …

Near-Infrared Chiral Plasmonic Metasurface Absorbers, Leixin Ouyang, Wei Wang, Daniel Rosenmann, David A. Czaplewski, Jie Gao, Xiaodong Yang

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Chirality plays an essential role in the fields of biology, medicine and physics. However, natural materials exhibit very weak chiroptical response. In this paper, near-infrared chiral plasmonic metasurface absorbers are demonstrated to selectively absorb either the left-handed or right-handed circularly polarized light for achieving large circular dichroism (CD) across the wavelength range from 1.3 µm to 1.8 µm. It is shown that the maximum chiral absorption can reach to 0.87 and that the maximum CD in absorption is around 0.70. The current chiral metasurface design is able to achieve strong chiroptical response, which also leads to high thermal CD for …

A Socioecological Approach To Online Dating Goals And Self-Presentational Strategies In North American And Chinese Cultures, Cheuk Yue, Cherry Wan

Bachelor of Social Sciences – Senior Theses

In this study, a content analysis investigating the relationship goals and self-presentational strategies on online daters’ personal advertisements from both North America (n = 300) and Hong Kong China (n = 300) was conducted. Significant differences between the two cultures were found by adopting a socio-ecological approach. Great cross-cultural differences were found. Compared with Chinese, the North American were more likely to seek for an open and casual relationship, namely sexual interests and friendship, self-improvement and showing own uniqueness. In contrast, Chinese were more likely to initiate a committed relationship such as soulmate and romantic activities, express loneliness and resistant …

Isobavachalcone Sensitizes Cells To E2-Induced Paclitaxel Resistance By Down-Regulating Cd44 Expression In Er+ Breast Cancer Cells, Junfeng Shi, Yi Chen, Wenxing Chen, Cuiju Tang, Honghong Zhang, Yuetong Chen, Xiuwei H. Yang, Zhi Xu, Jingsun Wei, Jinfei Chen

Pharmacology and Nutritional Sciences Faculty Publications

Oestrogen receptor (ER) is expressed in approximately 60%‐70% of human breast cancer. Clinical trials and retrospective analyses have shown that ER‐positive (ER+) tumours are more tolerant to chemotherapeutic drug resistance than ER‐negative (ER−) tumours. In addition, isobavachalcone (IBC) is known as a kind of phytoestrogen with antitumour effect. However, the underlying mechanism of IBC in ER+ breast cancer needs to be elucidated further. Our in vitro experiments showed that IBC could attenuate 17β‐estradiol (E₂)‐induced paclitaxel resistance and that E₂ could stimulate CD44 expression in ER+ breast cancer cells but not in ER− cells. Meanwhile, E₂ could …

Troubled Waters: Threats And Extinction Risk Of The Sharks, Rays And Chimaeras Of The Arabian Sea And Adjacent Waters, Rima W. Jabado, Peter M. Kyne, Riley A. Pollom, David A. Ebert, Colin A. Simpfendorfer, Gina M. Ralph, Shakha S. Al Dhaheri, K. V. Akhilesh, Khadeeja Ali, Mohamud Hassan Ali

Biological Sciences Faculty Publications

The extinction risk of sharks, rays and chimaeras is higher than that for most other vertebrates due to low intrinsic population growth rates of many species and the fishing intensity they face. The Arabian Sea and adjacent waters border some of the most important chondrichthyan fishing and trading nations globally, yet there has been no previous attempt to assess the conservation status of species occurring here. Using IUCN Red List of Threatened Species Categories and Criteria and their guidelines for application at the regional level, we present the first assessment of extinction risk for 153 species of sharks, rays and …

Compound 1 possessed selectivity toward the NCI-H929 cell line (IC …

Carnivorous Pitcher Plants Eat A Diet Of Certain Spiders, Regardless Of What's On The Menu, Marc A. Milne, Deborah A. Waller

Biological Sciences Faculty Publications

The purple pitcher plant, Sarracenia purpurea, is a low-lying carnivorous plant that uses pitcher-shaped leaves to catch arthropod prey for nutrition. Spiders make up a significant portion of these prey. To determine the tendency of specific spider taxa to be captured by the plant, we compared the composition (by taxonomic family) of three spider assemblages: those captured by the plant, those residing on or over the plant, and those found nearby in the local environment. Although there were some broad similarities within the three spider assemblages, significant differences existed when specific families and guilds were considered. While some families …

Quantification Of Cloud Condensation Nuclei Effects On The Microphysical Structure Of Continental Thunderstorms Using Polarimetric Radar Observations, Kun-Yuan Lee

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Aerosols serving as cloud condensation nuclei (CCN) are crucial to the microphysical structure of thunderstorms. They can also alter the rate of cloud microphysical processes, the moisture profile and the local temperature as a result of latent heating/cooling in the early stage of thunderstorm development. Continental thunderstorms are characterized by high complexity and are highly influenced by environmental conditions. The purpose of this study is to determine the influences of CCN concentration on the microphysics of continental thunderstorms, using a sample of storms from northwestern Oklahoma. The Weather Surveillance Radar-1988 Doppler (WSR-88D) at Vance Air Force Base (KVNX) was upgraded …

Depression Among Chinese Lbc: Understanding Depression In Context Of A Family-Oriented Culture, Lanyan Ding

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Background: Left-Behind Children (LBC) refers to children who are under 18 and must live separately from at least one of their parents for longer than six months because of parents’ labor migration (Zhou & Duan, 2006). The long-term family separation might greatly impair the family environment and increase the risk of developing depression among LBC. This research examined the relationships among family structure (left-behind status), caregiving, and child depression using archival data from the China Family Panel Studies (CFPS) in both cross-sectional and longitudinal analyses.

Methods: In Study 1, multilevel regression analyses investigated how contextual factors (family structure …

Studies On The Physicochemical Characterization Of Flours And Protein Hydrolysates From Common Beans, Hollman Andres Motta Romero

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Pulses represent a rich source of nutrition and have several potential health benefits such as the reduction of the risk of developing cardiovascular diseases, obesity, and diabetes. Beans from the species Phaseolus vulgaris and Cicer arietinum are important crops raised in some regions of the United States, including Western Nebraska. Nevertheless, the traditional preparation procedures involved in the cooking of these beans are tedious and time-consuming, thus leading to the underutilization of these resources. Therefore, the present work focused on evaluating alternative utilizations of these beans in order to improve their economic value.

One alternative to improve the consumption of …

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

School of Natural Resources: Dissertations, Theses, and Student Research

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made …

Groundwater Recharge Response To Reduced Irrigation Pumping In Western Nebraska, Justin Philip Gibson

School of Natural Resources: Dissertations, Theses, and Student Research

Given current and continued investment in irrigation scheduling technologies, a need exists to better estimate the longevity and magnitude of water savings at watershed level to avoid the paradox of irrigation efficiency. This paradox occurs within a watershed as not all irrigation inefficiencies lead to the system losing water. For example, irrigation pumping rates in excess of crop water demand may lead to enhanced groundwater recharge or surface runoff that migrates to a stream. Thus, increases in efficiency may not lead to similar magnitudes of water savings. I hypothesize that water savings longevities are short given previous work demonstrating rapid …

Comorbidities, Risk, And Socioeconomic Factors Of Uninsured Cancer Survivors, Abu-Sayeef Mirza, Smitha Pabbathi, Yuanyuan Lu, Noura Ayoubi, Aldenise P. Ewing, Michael Jaglal, Richard Roetzheim

College of Medicine & TGH Faculty Publications

Cancer patients can be well-connected to resources during treatment but become lost to follow-up and subsequently may receive treatment in free clinics for chronic morbidities. Few studies have examined outcomes for uninsured patients with cancer histories in free clinics, but research examining socioeconomic determinants emphasizes poor cancer outcomes for patients with lower socioeconomic statuses (SES).

Demographic data and chronic disease measures were extracted from medical charts of patients treated in 8 free clinics in 2016 in Tampa Bay. Descriptive statistics and Pearson correlation coefficients were used to demonstrate relationships between socioeconomic factors, cancer diagnoses, and comorbidities. Charlson Comorbidity Index (CCI) …

Biological Effects On Uranium Isotope Fractionation (238U/235U) In Primary Biogenic Carbonates, Xinming Chen, Stephen J. Romaniello, Achim D. Herrmann, Elias Samankassou, Ariel D. Anbar

Faculty Publications

© 2018 Elsevier Ltd Determining whether U isotopes are fractionated during incorporation into biogenic carbonates could help to refine the application of 238U/235U in CaCO3 as a robust paleoredox proxy. Recent laboratory experiments have demonstrated that heavy uranium (U) isotopes were preferentially incorporated into abiotic aragonite, with an isotope fractionation of ∼0.10‰ (238U/235U). In contrast, no detectable U isotope fractionation has been observed in most natural primary biogenic carbonates, but the typical measurement precision of these studies was ±0.10‰ and so could not resolve a fractionation of the magnitude observed in the laboratory. To resolve this issue, we have developed …
