Maritime Trade And Imperial Ambitions: Yemeni Politics And Trade In The Indian Ocean World (626/1228-858/1454), Beck Sjostedt

Theses and Dissertations

This thesis explores the role of Yemen, particularly under the Rasūlid dynasty (626/1228-858/1454) in the medieval Indian Ocean trade. I argue that the Rasūlids attempted to create an “imperial maritime space” wherein Yemen would be the imperial core, and the western Indian Ocean and Red Sea the subjugated peripheries. While the Rasūlids managed to organize state power towards their imperial project via diplomacy, military and naval expansion, and a robust and efficient bureaucracy, they never fully realized their goal of creating a thalassocratic empire in the western Indian Ocean. Nonetheless, medieval Yemen played a significant role in the political, social, …

Isomorphism And Network Governance:A Reflection Of The Thai Elderly Quality Of Life Development And Career Promotion Centers, Ratchaphon Amsuk, Piyamart Tupmongkol, Phengkamon Marnarath, Siriprapa Promma

Asia-Pacific Social Science Review

This study aims to examine isomorphism, network governance, and the spectrum of participation, as classified by the International Association of Public Participation, in the management of the elderly quality of life development and career promotion centers (EQCCs). This study applied the concepts of isomorphism from institutional theory, network governance, and spectrum of participation as defined by the International Association for Public Participation (IAP2), as the instruments for analysis. The findings revealed that EQCCs’ isomorphism emerged before and after the establishment. The three isomorphism mechanisms—coercive, mimetic, and normative—affected the isomorphism of the EQCCs, leading to organization homogenization. However, the management of …

Measuring And Modeling Nonlinear Vibrations In Structures With Mechanical Joints, Suzanna Gilbert

Theses and Dissertations

Many assembled structures have bolted or riveted joints. Aside from providing a convenient method of assembly, mechanical joints have an important effect on the structure's dynamic response to its environment. Friction and microslip within the joints help to damp out unwanted vibration. However, the joints also introduce nonlinearity into the response. Most notably, the natural vibrational modes of the structure no longer have constant natural frequencies and damping ratios. Rather, they shift as a function of vibration amplitude. Several methods exist to characterize the dynamics of nonlinear systems, yet they are generally validated on simple benchmark structures, and many still …

The Negotiation Of Identities Through Humorous Discourse In Political Resistance: An Analysis Of Bassem Youssef's 'The B+ Show', Howaida Aref

Theses and Dissertations

This study examines the strategic use of humorous discourse in negotiating identities and expressing political resistance during the 2011 Egyptian Revolution, focusing on Bassem Youssef's satirical YouTube show, "The B+ Show." Employing a mixed-method approach that combines Grice's maxims of cooperative communication and Fairclough's critical discourse analysis framework, the research investigates how humor functioned as a tool for challenging hegemonic narratives and power dynamics through constructing and deconstructing identities in a volatile sociopolitical context. The analysis reveals that Youssef skillfully exploited various discursive resources, particularly intertextuality and the flouting of conversational maxims, to generate implicatures that effectively debunked negative representations …

Methodological Approaches For Enhancing The Energy Efficiency Of Waste-To-Energy Biogas Systems, Evan Walls

School of Geography, Earth and Environmental Sciences

he invention of pottery played a crucial role in human history, promoting human settlement and the transition to an agricultural society [1,2]. Pottery first emerged in East Asia during the Late Pleistocene/Paleolithic across a diverse range of environmental settings, becoming more widespread with the climatic warming of the Holocene/Neolithic [3]. The relatively cold Mongolian Plateau was a key region for early human adaptation. Here, numerous archaeological sites have been discovered since the Upper Palaeolithic, including the earliest pottery sites dating back to approximately 12,000 years ago in the northern areas [4,5]. However, no pottery sites predating 10,000 cal a BP …

From this review, we saw an even bigger risk arises from the Koebner phenomenon. Specific disorders can exacerbate …

Platforms, Privacy, And Power: Examining Predictors Of Online Intimate Information Disclosure And Expression, Alexis Shore Ingber, Danielle Keats Citron, Jonathon W. Penney

Articles & Book Chapters

When intimate privacy is violated, self- and relational development is impaired to the detriment of individuals and society. Despite these costs, there is a lack of systematic empirical and theoretical study of intimate privacy and efforts to protect it. This research helps fill this void through two complementary studies. Through a longitudinal experimental design, results from Study 1 highlight that partner trust and response-efficacy were not only positively predictive of online intimate disclosure, but also strengthened following knowledge of intimate privacy protections. In Study 2, we find individuals are more likely to engage in public-facing online sexual expression if the …

Development And Validation Of A Pronation-Supination Testing Protocol For Rat Elbow Joint Function, Genevieve Jarrell

Mechanical Engineering and Materials Science Independent Study

Post-traumatic joint contracture (PTJC) of the elbow results in pain, stiffness, and loss of motion that can substantially impair daily function. While flexion-extension deficits in PTJC have been well characterized, the effects on pronation-supination remain poorly understood due to limited testing capability. The objective of this study was to develop and validate a method for quantifying rat elbow pronation-supination motion to better characterize elbow dysfunction. An existing load-controlled cyclic testing protocol was adapted using a rack-and-pinion system to convert linear displacement into forearm rotation, generating torque-displacement curves from which range of motion (ROM) and stiffness were evaluated. The protocol was …
