Liberalization, Contention, And Threat: Institutional Determinates Of Societal Preferences And The Arab Spring In Tunisia And Morocco, Matthew Thomas Lacouture

Dissertations and Theses

Why do revolutions happen? What role do structures, institutions, and actors play in precipitating (or preventing) them? Finally, What might compel social mobilization against a regime in the face of potentially insurmountable odds? These questions are all fundamentally about state-society (strategic) interactions, and elite and societal preference formation over time. The self-immolation of Muhammad Bouazizi in Sidi Bouzid on December 17, 2010, served as a focal point upon which over twenty years of corrupt, coercive authoritarian rule were focused into a single, unified challenge to the Ben Ali regime. The regime's brutality was publicized via social media activism and satellite …

Enzymatic Control Of The Related Pathways Of Fatty Acid And Undecylprodiginine Biosynthesis In Streptomyces Coelicolor, Renu Singh

Dissertations and Theses

Streptomyces coelicolor produces fatty acids for both primary metabolism and for production of the components of natural products such as undecylprodiginine. Primary metabolism makes the longer and predominantly branched-chain fatty acids, while undecylprodiginine utilizes shorter and almost exclusively straight chain fatty acids. The first step in fatty acid biosynthetic process is catalyzed by FabH (β-ketoacyl synthase III), which catalyzes a decarboxylative condensation of an acyl-CoA primer with malonyl-acyl carrier protein (ACP). The resulting 3-ketoacyl-ACP product is reduced by NADPH-dependent FabG into 3-hydroxyacyl-ACP, which is dehydrated by FabA to form enoyl-ACP. The NADH-dependent FabI (InhA) completes the cycle. Subsequent rounds of …

How The Eu Membership Has Affected Turkey’S Political Environment, Emre Kantarci

Dissertations and Theses

This thesis aims to analyze and argue how the membership process for the European Union has affected Turkish politics and to what outcome it led Turkey. Starting with the EU candidacy, Turkey has gone through radical political changes, most of which have proved negative given the history of the country. Such changes included the weakening of the Turkish Army, strengthening of Kurdish separatism, the rise of Islamic-oriented parties, and Turkey’s political shift away from western-orientation. First, the EU and its history will be analyzed analyzed as a way to illustrate the requirements for Turkey as a candidate nation. Afterwards, I …

Morphology Of Brain Sulci Trabeculae And Its Effect On Brain During Impacts, Sharlin Anwar

Dissertations and Theses

Traumatic brain injury (TBI) is an intracranial injury caused by direct contact or non-contact head impacts to the brain. TBI is a major problem that accounts for high incidents of hospitalizations each year. Thus, it is important to understand and predict the occurrence of TBI in an impact. It has been shown that the subarachnoid space (SAS) trabeculae play an important role in damping the effect of an impact, thus reducing the injuries. However, the influence of sulci parameters and the sulci trabeculae in TBI due to impact is unexplored. Studies have shown that inclusion of sulci in brain models …

Health, Wellbeing, And Academic Achievement Among Urban College Students, Elise Tanzini

Dissertations and Theses

The post-secondary educational environment is full of demands—both academically and outside of the direct college setting—and as a result, stress is a prevailing concern for college students. Chronic, high levels of stress have been linked to a number of negative health outcomes, such as anxiety and depression, and academic outcomes, such as lower academic achievement. Using a diverse sample of undergraduate and masters students [n=84; mean (SD) age = 22.89 (5.99) years] from an urban, public college, the current study measured students’ experiences of stress (Perceived Stress Scale) and the adaptive and maladaptive strategies they utilized to cope with stress, …

Gendered Political Economy: The Economic And Social Factors That Affect Women’S Political Participation, Ginger Albertson

Dissertations and Theses

There is a prevailing attitude that increasing women’s economic participation leads to their empowerment, or increases their agency in influencing decision making. This is despite large data evidence to the contrary and acknowledgement by financial institutions that a link cannot be established. This thesis examines what impact labor participation has on women’s influence in their community and their political participation, how non-income related skills like advocacy increases women’s self-confidence and agency, and the role non-formal training and networks play in increasing women’s participation in decision making and political participation. I find that when conducting a data comparison there does not …

The Synthesis And Characterization Of Dual-Modified Carboxymethylcellulose For Bioadhesive Applications, Fabrice Bernard

Assessment Of Injection Behavior Of Commercially-Available Bone Bsms For Subchondroplasty Procedures, Dinely A. Colon

Dissertations and Theses

Subchondroplasty is a procedure that utilized bone substitutes materials (BSMs) or bone cement to correct bone defects in the subchondral bone. The two main materials used to compose BSMs are poly-methyl-methacrylate (PMMA) and calcium phosphate cement (CaP). Currently, there is no optimal bone material substitute in the market that can provide both the adequate mechanical support and the right viscosity to reach the affected area in the subchondral bone. In addition, there is also no established parameter for their proper use, based on the defect size and location. PMMA possesses comparable mechanical properties to bone (i.e. 96 MPa in compressive …
