As robots become more prevalent, the need is growing for efficient yet stable control systems for applications with humans in the loop. As such, it is a challenge for scientists and engineers to develop robust and agile systems that are capable of detecting instability in teleoperated systems. Despite how much research has been done to characterize the spatiotemporal parameters of human arm motions for reaching and gasping, not much has been done to characterize the behavior of human arm motion in response to control errors in a system. The scope of this investigation is to investigate human corrective actions in response to error in an anthropomorphic teleoperated robot limb. Characterizing human corrective actions contributes to the development of control strategies that are capable of mitigating potential instabilities inherent in human-machine control interfaces. Characterization of human corrective actions requires the simulation of a teleoperated anthropomorphic armature and the comparison of a human subject's arm kinematics, in response to error, against the human arm kinematics without error. This was achieved using OpenGL software to simulate a teleoperated robot arm and an NDI motion tracking system to acquire the subject's arm position and orientation. Error was intermittently and programmatically introduced to the virtual robot's joints as the subject attempted to reach for several targets located around the arm. The comparison of error free human arm kinematics to error prone human arm kinematics revealed an addition of a bell shaped velocity peak into the human subject's tangential velocity profile. The size, extent, and location of the additional velocity peak depended on target location and join angle error. Some joint angle and target location combinations do not produce an additional peak but simply maintain the end effector velocity at a low value until the target is reached. Additional joint angle error parameters and degrees of freedom are needed to continue this investigation.

For many years, the countries of Sub-Saharan Africa, like many other unindustrialized nations, followed the internally-oriented import substitution policies developed by theoreticians like Raul Prebisch. These measures were meant to force nations to develop their industrial capabilities in isolation from the rest of the world. However, these policies did little to improve the economy of many emerging countries. It was not until Asian countries switched to externally-oriented strategies that progress was made in their developing economies. In the early 1980s, a "Washington Consensus" was practiced that included a trade provision for the opening of emerging markets. Since then, many Sub-Saharan African nations have implemented policies that have opened up their markets to the rest of the world. However, most of these countries have not realized the benefits typically ascribed to open trade, causing some economists to doubt the economic growth benefits of trade liberalization. This thesis examines the connection between trade liberalization in Sub-Saharan Africa to review the consequences of recent trade reforms on the region's development and to identify some of the factors which contributed to individual countries successfully, or unsuccessfully, implementing trade liberalizing policies. It finds that the relationship between economic growth and trade liberalization is not as important as other growth factors and that there are multiple paths toward economic development.

Over the course of 2015-2017, the ASU-SCMA/UASGC Outreach program was developed at Arizona State University (ASU) to support both high school students and college students interested in supply chain management careers. In particular, the program targets the high school students of the Urban Assembly School for Global Commerce (UASGC) and the college students of the ASU Supply Chain Management Association (ASU-SCMA). High school students are partnered with college students in a year-long mentoring program that allows both parties to develop professional supply chain skills. The work of the ASU-SCMA/UASGC Outreach Program is particularly important because it provides UASGC with much needed resources to address urban poverty issues in New York using career and technical education. The Urban Assembly describes its student group as "at-risk, under-resourced youth," and of those youth: - 85% are low-income - 83% enter high school below grade level in at least one subject - 20% require Individualized Education Plans (Special Needs) (urbanassembly.org). The Outreach Program addresses the above issues by providing the high school students with collegiate mentors that develop supply chain and college readiness resources in the form of a case study, site tour, supply chain simulation and presentations. In order to be considered successful, the program must first, equip the high school mentees with tools and skills for a professional career, specifically supply chain management, that they would not otherwise be exposed to; and second, motivate the collegiate participants who are about to enter the workforce to continue to participate in mentoring throughout their careers. This program documents the efforts and results of the pilot year for the Outreach Program that took place from September 2016 through March 2017. Through this pilot program, it was determined that the ASU-SCMA/UASGC Outreach Program is effective and valuable. In fact, the program found that: - 75% of the high school students agreed or strongly agreed that the program helped them learn new business skills. - 75% of the high school students agreed that the program taught them new, interesting things about supply chain. - 75% of the high school students became more interested in college. 100% of the college mentors agreed or strongly agreed that they gained new and important supply chain and professional skills. The success of the pilot year has led to plans for the Outreach Program to become an annual project for ASU-SCMA. This is a program that will continue for the foreseeable future.

Since the global financial crisis of 2007-8, interest in worker-cooperatives and alternative forms of organization has surged. Mondragon, located in the Basque region of Spain, represents the largest federation of worker-cooperatives around the world, consisting of 98 cooperatives and 143 subsidiaries, which earned a total revenue of $14.5 billion in 2019. While previous attempts to establish a similar model have historically reached limited success, Mondragon has achieved a unique balance of remaining economically viable, on the one hand, and staying true to its founding principles of democratic governance, on the other. This paper sets out to analyze the democratic structure and the cooperative culture at the heart of the Mondragon model, as well as the new type of human relationship that it fosters. In particular, this relationship is one in which individual well-being is bound up with communal well-being that avoids the antagonistic clash between the capital and labor.

This thesis will bring together students to engage in entrepreneurship by finding, measuring and sharing strategic market opportunities. From a student’s perspective, it will take a deep dive into the world of startup ecosystems, markets and trends utilizing both qualitative and quantitative market research techniques. The information gathered has been curated into a productive, meaningful manner, through a report titled “The State of Startups: A Student Perspective.” <br/> The first key theme of this thesis is that market intelligence can be a powerful tool. The second key theme is the power of knowledge implementation towards competitive strategies. The first section of the thesis will focus on identifying and understanding the current “startup” landscape as a basis on which to build strategic and impactful business decisions. This will be accomplished as the team conducts a landscape analysis focused on the student perspective of the student-based North American “entrepreneurial” ecosystem. The second section of the thesis will focus specifically on the personal experiences of student startup founders. This will be accomplished through the analysis of interviews with founders of the startups researched from the first section of the thesis. This will provide us with a direct insight into the student perspective of the student-based North American “entrepreneurial” ecosystem.

Long distance travel around the globe can potentially be revolutionized with the use of an intercontinental rocket that uses low earth orbit as its medium. This transport system can increase growth in many new businesses like tourism travel between the continents. This research evaluates the technical and non-technical possibilities of using a double-stage reusable rocket, where the second stage is also a reusable, rocket-powered passenger vehicle using a low earth orbit space journey with a stabilized re-entry method that ensures passenger comfortability. A potential network of spaceports spanning the globe is postulated within a range of 4,000 km to 8,000 km(2,160 nm to 4,320 nm) of each other, and each located within an hour by any other means of ground transport to population hubs greater than four million. This will help further connect the world as the journey from one major city to another would take at most an hour, and no point on the habited continents would be more than 4,000 km(2,160 nm) from a spaceport. It is assumed that the costs of an international first class flight ticket are in the thousands of dollars range showing how there is a potential market for this type of travel network. The reasoning and analysis, through a literature review, for an intercontinental rocket vehicle is presented along with the various aspects of the possibility of this kind of travel network coming to fruition in the near future.

Titanium has been and continues to be a popular metal across any form of manufacturing and production because of its extremely favorable properties. In important circumstances, it finds itself outclassing many metals by being lighter and less dense than comparably strong metals like steel. Relative to other metals it has a noteworthy corrosion resistance as it is stable when it oxidizes, and due to the inert nature of the metal, it is famously hypoallergenic and as a result used in a great deal of aviation and medical fields, including being used to produce replacement joints, with the notable limitation of the material being its cost of manufacturing. Among the variants of the metal and alloys used, Ti6Al4V alloy is famous for being the most reliable and popular combination for electron beam manufacturing(EBM) as a method of additive manufacturing. <br/>Developed by the Swedish Arcam, AB, EBM is one of the more recent methods of additive manufacturing, and is notable for its lack of waste by combining most of the material into the intended product due to its precision. This method, much like the titanium it is used to print in this case, is limited mostly by time and value of production. <br/>For this thesis, nine different simulations of a dogbone model were generated and analyzed in Ansys APDL using finite element analysis at various temperature and print conditions to create a theoretical model based on experimentally produced values.
