Research on human grasp typically involves the grasp of objects designed for the study of fingertip forces. Instrumented objects for such studies have often been designed for the simulation of functional tasks, such as feeding oneself, or for rigidity such that the objects do not deform when grasped. The goal of this thesis was to design a collapsible, instrumented object to study grasp of breakable objects. Such an object would enable experiments on human grip responses to unexpected finger-object events as well as anticipatory mechanisms once object fragility has been observed. The collapsible object was designed to be modular to allow for properties such as friction and breaking force to be altered. The instrumented object could be used to study both human and artificial grasp.

The generation of walking motion is one of the most vital functions of the human body because it allows us to be mobile in our environment. Unfortunately, numerous individuals suffer from gait impairment as a result of debilitating conditions like stroke, resulting in a serious loss of mobility. Our understanding of human gait is limited by the amount of research we conduct in relation to human walking mechanisms and their characteristics. In order to better understand these characteristics and the systems involved in the generation of human gait, it is necessary to increase the depth and range of research pertaining to walking motion. Specifically, there has been a lack of investigation into a particular area of human gait research that could potentially yield interesting conclusions about gait rehabilitation, which is the effect of surface stiffness on human gait. In order to investigate this idea, a number of studies have been conducted using experimental devices that focus on changing surface stiffness; however, these systems lack certain functionality that would be useful in an experimental scenario. To solve this problem and to investigate the effect of surface stiffness further, a system has been developed called the Variable Stiffness Treadmill system (VST). This treadmill system is a unique investigative tool that allows for the active control of surface stiffness. What is novel about this system is its ability to change the stiffness of the surface quickly, accurately, during the gait cycle, and throughout a large range of possible stiffness values. This type of functionality in an experimental system has never been implemented and constitutes a tremendous opportunity for valuable gait research in regard to the influence of surface stiffness. In this work, the design, development, and implementation of the Variable Stiffness Treadmill system is presented and discussed along with preliminary experimentation. The results from characterization testing demonstrate highly accurate stiffness control and excellent response characteristics for specific configurations. Initial indications from human experimental trials in relation to quantifiable effects from surface stiffness variation using the Variable Stiffness Treadmill system are encouraging.

The unprecedented rise of terrorist network ISIL has brought the revolutionary Salafi agenda to the forefront of global politics. This thesis provides an analysis of the ideology and an overview of ISIL. The research is comprised of reports on the organization from prominent think-tanks, books analyzing the tenets and thinkers of Salafi radicalism and original source material confiscated from ISIL's predecessor al-Qaeda in Iraq (AQI). An international coalition is posited as a solution to the threat as well as the Middle Eastern terrorist threat more broadly. However, the likelihood of such international cooperation is minimal, and the commitment it would require may make it unfeasible.

Within sixty years, the People’s Republic of China has risen from a struggling post-civil war state to the second largest economy in the world, comprising of 16.71 percent of the global economy as of 2015. While China has grown, its presence internationally has grown as well—China has utilized its capital to foment important relationships and foster soft power dynamics, making billions available in development aid and investment projects across the globe, most notably in Africa and Latin America, where Chinese goods have begun to dominate the markets there as they have in American counterparts. However, within Latin America China has been investing in countries that are traditionally seen as “risky” financial investments. This paper hypothesizes that the returns on Chinese investments in Latin America are not financial, but political—that China is investing in expansion of its soft-power and legitimizing its beginnings of global hegemony. The paper also explores the success of these initiatives by comparing the level of Chinese investment to changes in Latin American foreign policy alignment, discourse, and agreements through utilizing case studies of Venezuela and Bolivia.

Most daily living tasks consist of pairing a series of sequential movements, e.g., reaching to a cup, grabbing the cup, lifting and returning the cup to your mouth. The process by which we control and mediate the smooth progression of these tasks is not well understood. One method which we can use to further evaluate these motions is known as Startle Evoked Movements (SEM). SEM is an established technique to probe the motor learning and planning processes by detecting muscle activation of the sternocleidomastoid muscles of the neck prior to 120ms after a startling stimulus is presented. If activation of these muscles was detected following a stimulus in the 120ms window, the movement is classified as Startle+ whereas if no sternocleidomastoid activation is detected after a stimulus in the allotted time the movement is considered Startle-. For a movement to be considered SEM, the activation of movements for Startle+ trials must be faster than the activation of Startle- trials. The objective of this study was to evaluate the effect that expertise has on sequential movements as well as determining if startle can distinguish when the consolidation of actions, known as chunking, has occurred. We hypothesized that SEM could distinguish words that were solidified or chunked. Specifically, SEM would be present when expert typists were asked to type a common word but not during uncommon letter combinations. The results from this study indicated that the only word that was susceptible to SEM, where Startle+ trials were initiated faster than Startle-, was an uncommon task "HET" while the common words "AND" and "THE" were not. Additionally, the evaluation of the differences between each keystroke for common and uncommon words showed that Startle was unable to distinguish differences in motor chunking between Startle+ and Startle- trials. Explanations into why these results were observed could be related to hand dominance in expert typists. No proper research has been conducted to evaluate the susceptibility of the non-dominant hand's fingers to SEM, and the results of future studies into this as well as the results from this study can impact our understanding of sequential movements.

Electromyography (EMG) and Electroencephalography (EEG) are techniques used to detect electrical activity produced by the human body. EMG detects electrical activity in the skeletal muscles, while EEG detects electrical activity from the scalp. The purpose of this study is to capture different types of EMG and EEG signals and to determine if the signals can be distinguished between each other and processed into output signals to trigger events in prosthetics. Results from the study suggest that the PSD estimates can be used to compare signals that have significant differences such as the wrist, scalp, and fingers, but it cannot fully distinguish between signals that are closely related, such as two different fingers. The signals that were identified were able to be translated into the physical output simulated on the Arduino circuit.

The difficulty of measuring complex goals within nongovernmental organizations is well detailed in nonprofit management literature. For many years, NGOs have faced obstacles ranging from the technical difficulties of measuring intangible missions to ambiguous or unreliable performance criteria to political issues in the design of measurement systems that cater to diverse stakeholders. But despite the challenges, many nongovernmental organizations and researchers are rising to the challenge to design and implement effective systems of measurement. This thesis outlines the lessons learned from a study of the history and development of performance measurement, existing measurement systems and their implementation, as well as various insights gained from interviews conducted in Spring 2013 with leaders of nonprofit and nongovernmental organizations that are facing or that have faced these and many more obstacles in performance management. With these goals, this paper will strive to answer two main questions. What are performance measures and how do they differ by sector? What are performance measurement systems and why are they important?

Energiewende refers to the final legislation that sealed the decision to phase out Germany's nuclear power plants prematurely following the Fukushima nuclear disaster. This policy has been in place as of 2011, however, there has been little research done on the comprehensive effects of it within Germany, on German global relationships and obligations. As such, this paper has identified the top areas that have been affected by the legislation as the climate sector, the humanitarian sector and the security sector. In addition to identifying these areas, they have analyzed in the international sphere and this is analysis is used to determine the impact that the German legislation has on political realities in surrounding countries. The impacts are then compared to German obligations, as outlined in numerous treaties from within the three main areas discussed. Not only that, but the effects are also examined within the domestic sphere. The domestic effects are also compared to German obligations from international treaties, while focusing on high priority German issues, such as poverty. This paper ultimately examines the real policy influence that Germany has exhibited as a result of enacting a unique, and ambitious energy policy in a time in which many are still uncertain of the safety, or lack thereof, of nuclear power. The aim is to provide Germany, and countries beginning to question the role of nuclear power, with concurrent solutions to ensure a successful phase out that allows adherence to international and domestic obligations while also illustrating the positive role that nuclear power can play in energy production and policy.

The HIV pandemic spawned a global biomedical research effort which continues today. Because of multinational clinical studies, doctors and health officials possess more tools than ever before for the effective prevention and treatment of HIV/AIDS. The relationship between the United States and Sub-Saharan African nations features prominently within this global research effort. More specifically, many of the most significant HIV-related research findings emanate from clinical trials with a unique multinational configuration: the study protocol is largely designed and funded by American sources but executed at clinical research sites in Sub-Saharan African countries like South Africa and Zimbabwe. This thesis investigates the context and ethics of this configuration, with a focus on US-backed trials conducted in South Africa specifically. Using data collected from semi-structured interviews conducted at South African HIV clinical research sites, this thesis uncovers two significant ethical problems: insufficient benefits delivered to South African clinical trial participants, and informal processes occurring alongside formal protocol. By examining scope, effects, and implications of these problems, it becomes clear that although this research system delivers powerful results, there exists room for improvement.
