Description
South Mountain is the largest municipal park in the nation. It is a bundled amenity, providing a series of linked services to the surrounding communities. A dataset of 19,209 homes in 155 neighborhoods within three miles of the park was utilized in order to complete a hedonic estimation for two nearby urban villages, Ahwatukee Foothills and South Mountain Village. Measures of access include proximity to the park, trailhead access, and adjacency to the park. Two regressions were estimated, the first including lot characteristics and subdivision fixed effects and the second using the coefficients for each subdivision as the dependent variable. These estimates describe how the location of a house in a subdivision contributes to its conditional mean price. As a result they offer a direct basis for capturing amenities measured at the neighborhood scale on home values. Park proximity, trailhead access and adjacency were found to significantly influence the price of homes at the 5% confidence level in Ahwatukee, but not in South Mountain Village. The results of this study can be applied to issues of environmental justice and park access in determining which areas and attributes of the park are associated with a high premium. Though South Mountain was preserved some time ago, development and future preservation in the City of Phoenix can be informed by such studies.

AARP estimates that 90% of seniors wish to remain in their homes during retirement. Seniors need assistance as they age, historically they have received assistance from either family members, nursing homes, or Continuing Care Retirement Communities. For seniors not wanting any of these options, there has been very few alternatives. Now, the emergence of the continuing care at home program is providing hope for a different method of elder care moving forward. CCaH programs offer services such as: skilled nursing care, care coordination, emergency response systems, aid with personal and health care, and transportation. Such services allow seniors to continue to live in their own home with assistance as their health deteriorates over time. Currently, only 30 CCaH programs exist. With the growth of the elderly population in the coming years, this model seems poised for growth.

Description
Catastrophe events occur rather infrequently, but upon their occurrence, can lead to colossal losses for insurance companies. Due to their size and volatility, catastrophe losses are often treated separately from other insurance losses. In fact, many property and casualty insurance companies feature a department or team which focuses solely on modeling catastrophes. Setting reserves for catastrophe losses is difficult due to their unpredictable and often long-tailed nature. Determining loss development factors (LDFs) to estimate the ultimate loss amounts for catastrophe events is one method for setting reserves. In an attempt to aid Company XYZ set more accurate reserves, the research conducted focuses on estimating LDFs for catastrophes which have already occurred and have been settled. Furthermore, the research describes the process used to build a linear model in R to estimate LDFs for Company XYZ's closed catastrophe claims from 2001 \u2014 2016. This linear model was used to predict a catastrophe's LDFs based on the age in weeks of the catastrophe during the first year. Back testing was also performed, as was the comparison between the estimated ultimate losses and actual losses. Future research consideration was proposed.

Description
We examine the bias resulting from temporal and spatial aggregation of weather variables in environmental economics. In order to include temporally and/or spatially continuous environmental variables (such as temperature and precipitation), many studies discritize them. The finer the scale of discrization chosen, the more difficult it can be to obtain a complete and reliable data set. Studies performed at very fine scales often find tighter and more dramatic relationships between variables such as temperature and income per capita. We examine this question by repeating the same empirical study at various temporal and spatial scales and comparing the resulting parameter estimates.

Description
This paper examines the multifaceted challenges surrounding college students' nutrition, with a specific focus on Arizona State University (ASU). Examining economic shifts, psychological influences, nutrition knowledge, and body image dynamics, it reveals the profound impact on students' food security and eating behaviors. Despite existing initiatives, persistent gaps in resources remain, necessitating comprehensive interventions to support students effectively. In response, "The Ultimate Health Resource for ASU Students," a website, was developed as an innovative solution. This platform aims to empower students by providing a centralized hub to access vital resources, connect with peers, and discover nutritious recipes. Proposed strategies encompass expanding food pantry offerings, developing mobile applications for nutritional guidance, and fostering partnerships with local organizations. By tackling these challenges head-on and fostering a culture of support, ASU can ensure that all students have equitable access to nutritious food options and the necessary resources to thrive academically and personally. The website serves as a place of empowerment, offering practical solutions and fostering a sense of community among ASU students striving for optimal health and well-being.

Description
Bone loss affects millions of people every year posing a major public health problem. Currently, autograft and allograft bones are the only options for treating bone loss. Although, they pose many limitations including donor availability, immunogenicity risks, and the potential to carry a risk of disease and/or infection transmission to name a few. Therefore, there is a pressing clinical need to create a novel treatment that will promote bone repair. Alpha-ketoglutarate (aKG) was investigated as it plays an important role in cellular energy metabolism as a key intermediate in the Krebs cycle. It has been shown to stimulate the production of collagen in the bone repair process. However, controlling the release of aKG is important in being able to control where and how much new bone growth is stimulated. To address this aKG was delivered via a hyaluronic acid hydrogel and its release was controlled via the degradation of poly(alpha-ketoglutarate) microparticles (paKG MPs). paKG MPs were synthesized and characterized based on size, shape, and uniformity. The release of aKG from paKG MPs was evaluated, as well as the addition of paKG MPs into norbornene functionalized hyaluronic acid and maleimide functionalized hyaluronic acid hydrogels. Initial cell work was also done to grow osteoblasts for future work. It was found that paKG MPs were of the desired size and shape. The release of aKG from the paKG MPs was found to be sustained. The addition of paKG MPs in norbornene functionalized hyaluronic acid (NorHA) was found to be ineffective due to the opaqueness of the MPs. Maleimide functionalized hyaluronic acid (MaHA) hydrogels were chosen as an alternative delivery system for this reason. Future tests will be done on the addition of paKG MPs into MaHA hydrogels. Osteoblasts were also successfully grown and will be used in future studies.

Description
Mining is a key component of both the Brazilian and Chilean economies and accounts for an outsized share of these countries’ exports. Yet, it is a common target for environmental criticism, especially due to its impacts on local populations and ecosystems. Brazil and Chile have adopted markedly different trade strategies over the past three decades, most notably with regards to their involvement in international trade agreements. This paper investigates how these differences in trade policy since 1990 have affected the sustainability of each country’s mining sector by identifying and comparing the channels through which free trade agreements influence the environmental impacts of resource extraction.
