Assessing the Voids in the Space Liability Framework: Space Privatization and Space Debris

Description

This thesis seeks to examine shortcomings in space law by focusing on two interconnected aspects: privatization and space debris. The aspects of privatization and space debris will be examined under the context of the Outer Space Treaty (OST) and other relevant legal instruments. Privatization and space debris are two current challenges that the OST fails to regulate efficiently. While the OST was being drafted, the international community did not foresee problems such as privatization and space debris. This is significant because we are witnessing an increase in privatization of space activities and corporations as well as a massive accumulation of dangerous space debris. While the OST grants states the power to regulate private space companies and the accretion of space debris, national laws rarely align with the OST, leading to the abuse of international space laws. We will make recommendations at the end of the thesis in an effort to revise the use of soft language in the OST to attune national laws with international laws as well as address the growing ambiguity surrounding privatization and space debris.

This thesis surveys and analyzes applications of machine learning techniques to the fields of animation and computer graphics. Data-driven techniques utilizing machine learning have in recent years been successfully applied to many subfields of animation and computer graphics. These include, but are not limited to, fluid dynamics, kinematics, and character modeling. I argue that such applications offer significant advantages which will be pivotal in advancing the fields of animation and computer graphics. Further, I argue these advantages are especially relevant in real-time implementations when working with finite computational resources.

Hate in America and Across the Pond: Analysis of Case Law and the Emerging Differences in Free Speech Rights across Two Western Societies

Description

Normally, the United States and most of Europe are grouped into the same category as “Western countries”, yet their ideological differences have become larger in the last 50 years, especially in regards to free speech/expression protections. This raises the possibility that extremely broad free speech/expression protections aren’t intrinsic values of a Western society, but are instead an American experiment that was gradually adopted by Western Europe. Analyzing historical documents from both Europe and the United States, this becomes much more of a probability than a possibility and would help explain the recent differences in case law regarding free speech rights in American and European jurisprudence. Furthermore, Europe is also experiencing a potential threat to social stability in the form of massive, sudden demographic shifts, something that America has not experienced on nearly the same scale. Due to the heightened sensitivity towards hateful expression resulting from such a demographic shift, governmental action in the form of restrictions on racially, religiously, and ethnically charged forms of expressions may be deemed necessary in order to preserve social cohesion. Often throughout history, governments have deemed it necessary to limit free expression/speech and the spread of information in order to prevent any threat to its ability to rule, regardless of whether or not said government is tyrannical or democratized. Although not a direct threat to power, in a representative democracy social unrest created by increased division in the populace rooted in the spread of hateful ideology is nonetheless still a threat to those who depend on social harmony in order to govern in a representative democracy. In analyzing these two possible reasons for emerging differences and considering supporting textual and historical evidence, it becomes much clearer as to what the differences in case law and fundamental beliefs regarding the extent of free speech protections are attributable to.

Space Junk: Finding a Feasible Solution to Space Debris Removal (Including Recycling and Chemical Processes)

Description

Orbiting space debris is an active issue that affects the capability of space launch for future satellites, probes, and space shuttles, and it will become a nearly insurmountable problem without action. Debris of varying sizes and speeds orbit the Earth

Orbiting space debris is an active issue that affects the capability of space launch for future satellites, probes, and space shuttles, and it will become a nearly insurmountable problem without action. Debris of varying sizes and speeds orbit the Earth at a range of heights above the atmosphere and need to be removed to avoid damage to crucial equipment of active orbiting satellites including the International Space Station. Finding a feasible solution to space debris removal requires that several facets be covered to become a reality; these include being aware of the problem in magnitude and source. This literature assessment covers the magnitude of space debris in low-earth and geosynchronous orbit as well as collision events which have increased the amount of space debris. There have been efforts made by several space agencies to control the amount of space debris added to orbit by current and future launches over the last decade \u2014 serving as a temporary fix before removal can be executed. This paper explores known removal efforts through mitigation, projects conceived and tested by DARPA, related space policies and laws, CubeSat technology, and the cataloguing of known space debris. To make space debris removal a reality, roadblocks need to be removed to acquire permission from states or countries for space missions. For example, these restrictions are in place to protect the assets of several countries and organizations. Guidelines set to curb the growth of space debris fail to prevent the growth due to the restrictions for ownership rights making them not as effective. This paper covers space policy and laws, the economy, satellite ownership, international conflict, status of space debris, and the overall feasibility of space debris removal. It will then discuss currently proposed solutions for the removal of space debris. Finally, this paper attempts to weight the advantages and disadvantages of the idea that space debris removal should include the opportunity to recycle materials. For example, defunct satellites and other discarded space crafts could be used for future launches. It will conclude with a personal exploration of what materials can be recycled, what chemical processes can be used to break down materials, and how to combine recycling and chemical processes for space-based recycling stations between Earth and the moon. The overall question that drives the search for making space debris removal a reality is whether it is feasible in multiple areas including technologically, legally, monetarily, and physically.

My thesis project, "An Ethical Evaluation of the Practice of Psychiatric Patient Boarding in the Emergency Department" sets out to address a relatively nameless problem in the healthcare system in the United States. This problem is the boarding of psychiatric patients in emergency departments nationwide. What is psychiatric patient boarding? This term refers to the increasingly common practice of care provided to psychiatric patients upon arrival at an emergency department. When inpatient psychiatric beds or services are not available, "boarding" is performed by simply storing mentally ill patients in hallways or other emergency room areas while they wait for the availability of psychiatric treatment, which may take hours, or in more extreme cases has been cited to last for days at a time (Alakeson et. al, 2010). While any individual can expect to wait a prolonged period of time for medical care in the increasingly overcrowded emergency departments, the psychiatric patient experience is astonishingly unique. A psychiatric patient presenting, or arriving, at the ED in crisis can often times find him or herself not only waiting hours to be admitted and assessed as a medical patient would, but with a limited and ever attenuating supply of psychiatric treatment rooms and services, these patients will often times be harbored in an ED room designed for short-term medical treatment without care until psychiatric services become available. Patients can be left waiting for days for an in-patient vacancy; all the while not receiving true psychiatric treatment and in some cases being held against their will in a chaotic environment far from conducive for treatment of a mental health ailment. In this analysis, I will discuss and review aspects of psychiatric patient boarding from various literature, such as why boarding occurs from a hospital and historical standpoint, negative implications of boarding for psychiatric and medical patients, and the burden placed on the hospital when practicing psychiatric boarding. To learn further on the topic, I will share the results from 14 semi-structured, qualitative interviews performed with ED healthcare professionals, being physicians, charge nurses, nursing staff, and certified nursing assistants or patient safety advocates. This portion of my investigation is designed to offer a perspective that the literature cannot, being a first hand outlook on psychiatric boarding from those working on the front line, focusing on topics of all aspects, such as causation, consequences for all involved parties, and proposed solutions.

How the EnvZ/OmpR Two-component Regulatory System Affects fepA Gene Expression in Escherichia coli

This study focused on the connection between the EnvZ/OmpR two-component regulatory system and the iron homeostasis system in Escherichia coli, specifically how a mutant form of EnvZ11/OmpR is able to reduce the expression of fepA::lacZ, a reporter gene fusion in E. coli. FepA is one of several outer membrane siderophore receptors that allow extracellular siderophores bound to iron to enter the cells to power various biological processes. Previous studies have shown that in E. coli cells that expressed a mutant allele of envZ, called envZ11, which led to altered expression of various iron genes including down regulation of fepA::lacZ. The wild type EnvZ/OmpR system is not considered to regulate iron genes, but because these envz11 strains had downregulated fepA::lacZ, this study was undertaken to understand the connection and mechanisms of this downregulation. A large number of Lac+ revertants were obtained from the B32-2483 strain (envz11 and fepA::lacZ) and 7 Lac+ revertants that had reversion mutations not directly correcting the envZ11 allele were further characterized. With P1 phage transduction genetic mapping that involved moving a kanamycin resistance marker linked to fepA::lacZ, two Lac+ revertants were found to have their reversion mutations in the fepA promoter region, while the other five revertants had their mutations mapping outside the fepA region. These two revertants underwent DNA sequencing and found to carry two different single base pair mutations in two different locations of the fepA promoter region. Each one is in the Fur repressor binding region, but one also may have affected the Shine-Dalgarno region involved in translation initiation. All 7 reveratants underwent beta-galactosidase assays to measure fepA::lacZ expression. The two revertants that had mutations in the fepA promoter region had significantly increased fepA activity, with the revertant with the Shine-Dalgarno mutation having the most elevated fepA expression. The other 5 revertants that did not map in the fepA region had fepA expression elevated to the same level as that found in the wild type EnvZ/OmpR background. The data suggest that the negative effect of envZ11 can be overcome by multiple mechanisms, including directly correcting the envZ11 allele or changing the fepA promoter region.

Since the acceptance of Einstein's special theory of relativity by the scientific community, authors of science fiction have used the concept of time dilation to permit seemingly impossible feats. Simple spacecraft acceleration schemes involving time dilation have been considered by scientists and fiction writers alike. Using an original Java program based upon the differential equations for special relativistic kinematics, several scenarios for round trip excursions at relativistic speeds are calculated and compared, with particular attention to energy budget and relativistic time passage in all relevant frames.

My mother died after a long battle with breast cancer in 2008. I was only nine when she was first diagnosed, and so much of my life has been shaped by her struggle for survival. She will always be the most amazing women I have ever known, and she taught me more about life, kindness, hope, and overcoming the odds than anyone else. I want to share my experience with you as a friend \u2014 not as a doctor, or a counselor, but as a friend. I want to tell you some of my stories with the emotions behind them. I will share how I learned t cope with whatever situation came our way and how I found unexpected ways to help my mom. I want you to find solace through our shared emotions even if they are at different times in our journeys. This is why in the following chapters, my stories are not chronological but categorized through the major emotions that drove my stories. I hope this book can help those who find themselves in similar situations to the one I found myself in when my mom picked me up from fourth grade with a bandana on her head instead of her normal, beautiful brown hair. This thesis is a creative exploration of emotions and finding hope in times of great loss.
