Development Of Tripodal And Bipodal Ligand Frameworks And First-Row Transition Metal Reagents For Selective C-N Bond Construction Methodologies, Anshika Kalra

Doctoral Dissertations

"We present a family of anionic Mn(II) reagents supported by trisphenylamido- amlne frameworks that offer guidance with regards to ligand selection for developing C—N bond construction methodologies (extensively used in the synthesis of petrochemicals, household chemicals) through nitrene- transfer chemistry. We subsequently extend the study to include the corresponding Fe(II), Co(II), and Ni(II) reagents, to gain insights in their comparative reactivity/selectivity patterns. Attenuated levels of electrophilicity of anionic complexes proved to be more suitable for discriminating aromatic from aliphatic olefins for aziridination purposes, especially for Mn(II) complexes. However, in the case of Co(II) reagents, we observe that additional stereoelectronic parameters …

Secure Data Sharing In Cloud And Iot By Leveraging Attribute-Based Encryption And Blockchain, Md Azharul Islam

Doctoral Dissertations

“Data sharing is very important to enable different types of cloud and IoT-based services. For example, organizations migrate their data to the cloud and share it with employees and customers in order to enjoy better fault-tolerance, high-availability, and scalability offered by the cloud. Wearable devices such as smart watch share user’s activity, location, and health data (e.g., heart rate, ECG) with the service provider for smart analytic. However, data can be sensitive, and the cloud and IoT service providers cannot be fully trusted with maintaining the security, privacy, and confidentiality of the data. Hence, new schemes and protocols are required …

Synthesis Of Glycopharmaceuticals For The Treatment Of Microbial Sepsis, Nicholas Forsythe, Alexei Demchenko, Catherine Alex

Undergraduate Research Symposium

Carbohydrates (glycans) form the basis of all living organisms and, consequently, are ubiquitous both in nature as biologically active compounds and in medicine as pharmaceuticals. One important application of carbohydrate-based drugs (glycopharmaceuticals) is the treatment of microbial sepsis, an acute illness that causes 100,000+ human deaths annually in the US alone. Exposure of the patient’s blood system to E. coli bacteria causes a massive, and often fatal, immune response. One important cellular receptor that senses the bacterium and is critically involved in triggering the immune response is CD14. Significant efforts by our team and others have been made to develop …

Holding On To Who They Are: Pathways For Variations In Response To Toxic Workplace Behavior Among U.S. Intelligence Officers, Greta Creech

Antioch University Dissertations & Theses

The U.S. intelligence community is a critical mission industry responsible for protecting lives and safety in ways that impact the global security environment. Research on the deleterious impact of toxic workplace behavior on other critical mission fields, such as health care and the U.S. military, is robust. However, intelligence scholars publishing within the unclassified arena have been silent on the phenomenon, how personnel respond to it, and how it may impact the intelligence function. This lack of scholarship has afforded an opportunity to understand what constitutes toxic behavior in the intelligence environment and how it may affect U.S. national security …

Parasite And The Ideological Barriers To Emancipatory Politics, Soravis Jayanama

Journal of Social Sciences

In this essay, my contention is two-fold. One, Bong Joon-ho’s f ilm Parasite (2019) is not simply about class inequality but more importantly addresses the question “what is (not) to be done?”.To appreciate this point, we have to investigate it alongside Bong’s previous f ilms, especially Snowpiercer (2013) and Okja (2017). Although these three f ilms possess vastly different storylines,they all wrestle with this burning political question from different angles: seizure of state power and revolution (Snowpiercer), “folk politics” (Okja), and neoliberal privatization of social problems (Parasite). They all implicitly demand for better or more concrete visions of systemic transformation. …

Sickle Cell In A Poor Community In Haiti: Attention, Emotion, And Sleep, Sarajane Rodgers

Antioch University Dissertations & Theses

Hemoglobin disorders or inherited blood diseases affect about 5% of the world population. One main category of these disorders is sickle-cell disease (SCD). SCD can cause many physical complications, such as kidney problems, leg ulcers, and chronic pain. Less frequently discussed symptoms include complications like attention problems and emotion regulation. The study looked at a small sample of pediatric and adult patients (N=22) with SCD at a primary care clinic in a very poor community in Haiti, researching sleep and emotion regulation, given their shared neurobiological systems. As these symptoms can influence attention, the relationships among attention, emotion, and sleep …

Construction Of A Developmental Social Privilege Integration Scale, Abigail M. Martin

Antioch University Dissertations & Theses

The APA’s 2017 multicultural guidelines task psychologists with the aspirational goal of understanding the nuances of historical and contemporary systems of power, privilege, and oppression. Scholars such as Helms (1984) demonstrated the critical need to readjust psychology’s focus from oppressed groups to privileged groups. In her seminal 1988 article, McIntosh insisted that in order to “redesign social systems,” privileged groups must first acknowledge their “unseen dimensions” (p. 1). Similarly, Black and Stone (2005) and Johnson (2018) asserted the lack of social privilege awareness is part of American culture, which helps to maintain the invisibility of privilege and the status quo …

Adult Attachment Interview Classification: Comparing Two Coding Systems, Patricia M. Hastings

Antioch University Dissertations & Theses

Research on the Adult Attachment Interview (AAI) provides an opportunity to study the ways in which early childhood relational experiences might influence an individual over a lifetime. It is not yet clear, however, whether results from different coding systems for the AAI are equally useful. The first purpose of this study was to compare attachment classification distributions obtained from coding AAIs with the Berkeley and Dynamic-Maturational Model (DMM) coding systems. The second purpose was to explore whether AAI classifications derived from the Berkeley or DMM system were more strongly associated with mother and mother-child dyad outcome variables.

The Impact Of Assertiveness And Religiosity On The Expression Of Dissent Among U.S. Immigrant Nigerian Workers, Peter Osiabia Azorji

Walden Dissertations and Doctoral Studies

AbstractScholars have studied dissent in general, but few have focused on the impact of cultural contexts and characteristics on dissent. Literature on the influence of cultural factors on expression of disagreement in organizations, by immigrant Nigerian workers in the US has not received adequate attention. There is therefore a compelling need to bridge this gap. This quantitative nonexperimental correlation study examined the impact of assertiveness and religiosity (variables that may be influenced by culture), on expression of minority dissent among Nigerian immigrant workers in the United States. The inquiry was based on two theoretical models: Bourhis et al.’s interactive acculturation …

The Need For A Strong And Stable Federal Public Health Agency Independent From Politicians, Jacqueline Salwa, Christopher Robertson

Faculty Scholarship

The COVID-19 pandemic has revealed the precariousness of federal public health institutions in the United States, and how disastrously things can go when those institutions are undermined by political forces. Such institutions can be disbanded, underfunded, populated with incompetent political hacks, manipulated, or sidelined. As a field, public health in particular needs some political space, given that it requires deep scientific expertise and needs to communicate to the public clearly, reliably, and with authority to engender trust. Key public health agencies, such as the Centers for Disease Control and Prevention (CDC) in particular, should be buttressed against future political encroachment, …

Evaluation Of Various Separation Techniques For The Removal Of Actinides From A Rare Earth-Containing Solution Generated From Coarse Coal Refuse, Deniz Talan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rare earth elements have emerged as a vital commodity due to their significance in the production of high-tech devices as well as their utilization in defense and military systems. They are deemed critical due to potential scarcity, supply constraints, and the lack of minable concentrations. Therefore, alternative sources are needed to meet the demand and continue manufacturing rare earth-required products. Coal and coal by-products, in that regard, have presented a significant opportunity and proven to contain a considerable amount of rare earths. However, toxic elements such as thorium and uranium are frequently seen in the same mineralization as rare earths. …
