Nuclear weapons possess enormous potential to inflict damage on our world. The majority of countries in the world denounce the proliferation of these weapons, but a minority of countries have a desire to proliferate. This essay analyzes the impact of regime type and alliance strength to a nuclear state on protégé proliferation decisions. Prior research focuses on single factors in proliferation decisions and fails to take in to account the multi-faceted factors that influence the international system that states operate in. The analysis finds that regime type gives an indication about a state’s likelihood to proliferate, but does not explain proliferation choices comprehensively. Alliance strength plays a large role in a state’s security calculations and must be analyzed in conjunction to regime type to understand proliferation decisions.

An in-depth analysis on the effects vortex generators cause to the boundary layer separation that occurs when an internal flow passes through a diffuser is presented. By understanding the effects vortex generators demonstrate on the boundary layer, they can be utilized to improve the performance and efficiencies of diffusers and other internal flow applications. An experiment was constructed to acquire physical data that could assess the change in performance of the diffusers once vortex generators were applied. The experiment consisted of pushing air through rectangular diffusers with half angles of 10, 20, and 30 degrees. A velocity distribution model was created for each diffuser without the application of vortex generators before modeling the velocity distribution with the application of vortex generators. This allowed the two results to be directly compared to one another and the improvements to be quantified. This was completed by using the velocity distribution model to find the partial mass flow rate through the outer portion of the diffuser's cross-sectional area. The analysis concluded that the vortex generators noticeably increased the performance of the diffusers. This was best seen in the performance of the 30-degree diffuser. Initially the diffuser experienced airflow velocities near zero towards the edges. This led to 0.18% of the mass flow rate occurring in the outer one-fourth portion of the cross-sectional area. With the application of vortex generators, this percentage increased to 5.7%. The 20-degree diffuser improved from 2.5% to 7.9% of the total mass flow rate in the outer portion and the 10-degree diffuser improved from 11.9% to 19.2%. These results demonstrate an increase in performance by the addition of vortex generators while allowing the possibility for further investigation on improvement through the design and configuration of these vortex generators.

In which industry that has ever been profit generating, does a firm profit from their failure? The United States has a mass incarceration problem. With 25% of the world prison population residing in the US, spending on detention costs the US government $80 billion annually. Over 50% of the individuals incarcerated in America are of black or Latino descent. This massive growth in the incarcerated population of America began in the 1970s and with the passive support of American citizens has created an industry whose players profit from the detention of people. Currently, the privately run detention facilities in the United States hold 7% of state prisoners, 18% of federal prisoners, and nearly 75% of ICE's undocumented detainee population. The detention of people for profit is an idea rooted in the same profit motive that allowed the institution of slavery to flourish. However even after the 13th Amendment abolished slavery in the U.S., the oppressive forces behind slave-era economics have been perpetuated through legislation and policies that continued the stratification of society and reinforcement of the social order. With the help of corporate lobbyists, political action committees, and organizations such as the American Legislative Exchange Council, the corporate shareholders of private prisons, such as CoreCivic and The GEO Group, are able to directly align their profit-driven interests with those of federal and state legislators. By the incorporation of legislation and policy into state and federal law, the shareholders of private prisons are able to directly affect legislation as well as their own potential for profit. The justification for the usage of private prisons is thought to be seen in the price savings and flexibility that it provides for federal and state governments. However, due to the law enforcement contractor's exemption from public record laws, there is no clear evidence of where the cost savings occur, or even if there are cost savings at all. Is it ethical for a for-profit-prison corporation to be responsible for the care, security, and rehabilitation of an individual, when if they fail to rehabilitate the individual, it will add to the number of inmates under their control? The measure of a prison's failure to rehabilitate an inmate is considered the recidivism rate, and is affected when an inmate leaves a detention facility, commits another crime, then is arrested. This profit motive is causing our society to incarcerate increasing numbers of people in private prisons. For-profit prisons financially benefit from long-term incarceration and recidivism. The passive investments from public and private employees and institutions through investment corporations are the legs that allow the private prison industry to stand. Twenty-nine investment firms, such as The Vanguard Group and Fidelity Investments, own nearly two-thirds of the two largest players in the private prison industry. This includes the passive investments by public institutions such as the Arizona State University Foundation's $600 million endowment fund as well as the $500 million directly invested into CoreCivic and GEO Group from the University of Texas/ Texas A&M Investment Management Company. The goal of abolishing private prisons will require years of litigation against the giants of the industry as well as the governmental entities supporting them. However, we can start today by demanding divestiture by our school and similar institutions as well continuing to share the knowledge of the oppressive forces associated with the detention of individuals for profit.

The FIFA World Cup is one of the most anticipated, inspiring, and intense sporting events in the world. Soccer has integrated itself not only in sports circles, but also in politics, commerce, and society as a whole. The sport has about two hundred million active players and is still growing, especially in areas such as North America and Asia. As of mid-2007, FIFA’s membership included 208-member associations, making it not only one of the largest and most powerful sports governing bodies, but also one of the most popular in the world.
Since 1930—with the exception of the break for World War II—every four years, the world’s best national teams face off in a soccer tournament. The last two tournaments hosted by South Africa in 2010 and Brazil in 2014 will be the emphasis of this paper. Each tournament featured the thirty-two countries and captured a television audience of over three billion people throughout the month-long tournament, one billion of which tuned in for the final. For comparison, the Super Bowl XLIX where the New England Patriots defeated the Seattle Seahawks 28 to 24 was the most watched event in United States’ history with a viewership of 114.4 million people.
Countries spend years planning and preparing to win a bid to host one of these mega events. Bids are often times awarded eight to twelve years in advance. There has been a recent trend of developing countries hosting the FIFA World Cups and the future bids already awarded follow that trend. Many people ask the question of whether all the money spent on infrastructure, construction, and tourism to host this tournament and gain international exposure are really worth it? Simply put, the 2010 FIFA World Cup was valuable to South Africa while the 2014 FIFA World Cup was not worth the costs to Brazil.

Description
Shape Memory Polymers (SMPs) are smart polyurethane thermoplastics that can recover their original shape after undergoing deformation. This shape recovery can be actuated by raising the SMP above its glass transition temperature, Tg. This report outlines a process for repeatedly recycling SMPs using 3D printing. Cubes are printed, broken down into pellets mechanically, and re-extruded into filament. This simulates a recycling iteration that the material would undergo in industry. The samples are recycled 0, 1, 3, and 5 times, then printed into rectangular and dog-bone shapes. These shapes are used to perform dynamic mechanical analysis (DMA) and 3-point bending for shape recovery testing. Samples will also be used for scanning electron microscopy (SEM) to characterize their microstructure.

Description
The primary purpose of this paper is to analyze urgent care centers and explain their role within the U.S. healthcare system. The introduction of urgent care into the market for health care services has brought with it a new way for consumers to receive non-emergent healthcare outside of traditional hours. Urgent care is often cited as a plausible alternative to care received at an emergency department or primary care physician's office. One of the key questions the author attempts to answer is: "To what degree are urgent care centers an economic substitute to emergency departments or physician's offices?" This paper looks at both projected demand from currently operating urgent care centers and consumer preference surveys to estimate the willingness of consumers to use urgent care. The method used to accomplish this task has been compiling scholarly research and data on urgent care centers. After a thorough examination of relevant studies and datasets, urgent care centers have been found to be just as preferred as emergency departments when considering non-emergent cases, specifically among individuals aged 18-44. The clear majority of consumers still prefer visiting a primary care physician over an urgent care center when it comes to episodic care, however. When taking into account wait times, differences in cost, and ease of access, urgent care becomes much more preferred than an emergency department and weakly preferred to a physician's office. There are still some concerns with urgent care, however. Questions of capacity to meet demand, access for underserved communities, and susceptibility to adverse selection have yet to be fully explored.

Description
The purpose of this project is to develop a risk assessment tool for the University of California, Riverside (UCR). UCR is health enterprise that manages operations under an environment of innate and uncontrollable risks. Therefore, a risk assessment tool is highly advisable under California State Laws and federal laws. In the case of overlapping laws, federal law will always prevail unless State law explicitly states otherwise. California Health Information Privacy Manual states that California must follow numerous state guidelines and a federal set of guidelines called HIPAA (Health Insurance Portability and Accountability Act of 1996). HIPAA is put in place to protect and serve as an organizational tool to develop a stronger and more secure infrastructure of security measures within healthcare enterprises. Under HIPAA is a Security and Privacy Rule that was implemented by The U.S. Department of Health and Human Services (HHS) and will serve as the basis for the risk assessment tool I developed. The Security and Privacy Rule's main goal is to set a national standard of how electronic protected health information (ePHI) will be appropriately used and disclosed by organizations subject to this rule, also known covered entities. Covered entities include health plans, health care providers and health care clearinghouses unless specifically stated otherwise. Permitted uses and disclosures of PHI or ePHI are outlined in detail and covered entities are expected to follow all aspects of it that pertain to their role within a healthcare system. Under HHS, the Office of Civil Rights (OCR) strictly enforces the Security and Privacy Rules and can issue civil money penalties and/or other major consequences making this a sizable and critical issue in healthcare environments. Each risk and impact must be assessed to determine an overall risk score. This score will then determine what risks need to be immediately addressed and which risks are most critical to UCR. To do this, potential impacts were determined for each section. The impact score can be decided by using a chart that will be discussed in the development section. The likeliness of the risk can be determined by a UCR professional via the provided chart and an overall risk score can be assigned. From here, an action plan can be set and carried out to eliminate possible hazards and imminent risks. Once a Risk Assessment tool is developed, potential risks can be indentified and dealt with appropriately in regard to level of impact and the likelihood of the risk occurring. By reducing risk, a healthcare enterprise can gain greater financial stability, decrease loss and protect vital information that is critical to the success organization.

An aim of fundamental immunology is quantifying the diversity of the T cell receptor (TCR) repertoire to elucidate the vast recognition by T cells for protection against pathogen and cancer. The utilization of DNA origami nanostructures engineered to capture single cell paired TCR mRNA sequences has transformed the financial and time requirements of repertoire establishment. To further support this protocol, confocal laser scanning microscopy was implemented following transfection to visualize the stability of the DNA origami within primary immune lymphocytes.

Abstract: The Ultimate Fighting Championship or UFC as it is commonly known, was founded in 1993 and has quickly built itself into the world's foremost authority on all things MMA (mixed martial arts) related. With pay-per-view and cable television deals in hand, the UFC has become a huge competitor in the sports market, rivaling the popularity of boxing for almost a decade. As with most other sports, the UFC has seen an influx of various analytics and data science over the past five to seven years. We see this revolution in football with the broadcast first down markers, basketball with tracking player movement, and baseball with locating pitches for strikes and balls, and now the UFC has partnered with statistics company Fightmetric, to provide in-depth statistical analysis of its fights. ESPN has their win probability metrics, and statistical predictive modeling has begun to spread throughout sports. All these stats were made to showcase the information about a fighter that one wouldn't typically know, giving insight into how the fight might go. But, can these fights be predicted? Based off of the research of prior individuals and combining the thought processes of relevant research into other sports leagues, I sought to use the arsenal of statistical analyses done by Fightmetric, along with the official UFC fighter database to answer the question of whether UFC fights could be predicted. Specifically, by using only data that would be known about a fighter prior to stepping into the cage, could I predict with any degree of certainty who was going to win the fight?

Humans have traveled since the dawn of humanity over 200,000 years ago. As time progressed and technology increased, so too did human motivations and drivers for travel. This thesis aims to understand these human motivations and drivers, ultimately answering the question, "Why Travel?" To answer this question, this research starts from the earliest of humans, classifying groups of individuals across time into respective buckets based on a similar motivation. In doing so, four traveler segments were identified: the Survivors, the Inventors, the Adventurers, and the Colonists. Each segment describes an era in time of a specific group of humans, each distinctly aligning with a specific reason for travel. In the early 1800s, the advent of commercial travel altered the future of travel. This began with the invention of the locomotive and was followed by the airplane and automobile. With this onset of commercial travel, transportation arrives to its current state in 2018 with a new type of traveler: the Modern Traveler. This is a turning point in the history of travel, as prior to commercial travel, groups of individuals could be grouped under one specific reason. Post commercial travel, human motivations and drivers become diverse and discrete, with no two individuals sharing the same motivations. To further understand this human desire for travel in a modern sense, a survey was administered to uncover these drivers. The findings revealed one broad reason: humans travel for the experience. With this overarching view of travel, five drivers were also apparent. First, humans travel to visit friends and family. Secondly, family vacations are an important factor in the motivation to travel. Third, humans desire the ability to experience a culture different than their own. Fourth, humans are intrigued by new places and can be motivated to travel by the ability to have new experiences. Fifth and finally, rest and relaxation are a key driver in human travel. With a greater understanding as to "why humans travel," and the drivers behind the "experience" individuals seek through travel, such understandings could be used to segment these individuals into distinct traveler profiles. These segments, the Backpacker, the Solo-Traveler, the Groupie, the Cultural Traveler and the Party Lover, were used to better group motivations for travel. One conclusion can be drawn from this research: travel is diverse and so are travelers. One reason cannot define the motivations of a modern traveler, rather today's traveler is bound by multiple. However, segmenting an individual provides valuable insights into their own diverse traveler persona.
