Description
In the Alto Mayo Protection Forest (AMPF) of San Martín, Peru, unsustainable farming practices in coffee agroecosystems are the main drivers of deforestation and habitat loss. Previous studies indicate that across Latin American coffee farms, using shade-grown coffee result in higher biodiversity on the farms with a larger abundance of floral and faunal species. In AMPF, conservation agreements have been implemented between cultivators and Conservation International to ameliorate the environmental damages incurred by poor farming practices, as well as to increase cultivator livelihoods. To measure the effectiveness of these agreements, we compared camera trap data to drone-captured shade cover data to find the correlation between higher shade cover and biodiversity among subscriber plots. While our results showed no interrelationship between shade cover and species abundance or richness, this study was a small subset of the larger study, representing only 15% of the total subscriber plots and 24% of the overall sectors. Therefore, we predict that the results of the larger study will be more conclusive and will better indicate the predicted positive relationship between biodiversity and agroecology in AMPF.

Description
In baseball, a starting pitcher has historically been a more durable pitcher capable of lasting long into games without tiring. For the entire history of Major League Baseball, these pitchers have been expected to last 6 innings or more into a game before being replaced. However, with the advances in statistics and sabermetrics and their gradual acceptance by professional coaches, the role of the starting pitcher is beginning to change. Teams are experimenting with having starters being replaced quicker, challenging the traditional role of the starting pitcher. The goal of this study is to determine if there is an exact point at which a team would benefit from replacing a starting or relief pitcher with another pitcher using statistical analyses. We will use logistic stepwise regression to predict the likelihood of a team scoring a run if a substitution is made or not made given the current game situation.

The objective of this paper is to find and describe trends in the fast Fourier transformed accelerometer data that can be used to predict the mechanical failure of large vacuum pumps used in industrial settings, such as providing drinking water. Using three-dimensional plots of the data, this paper suggests how a model can be developed to predict the mechanical failure of vacuum pumps.

Description
The following report provides details on the development of a protective enclosure and power system for an anti-poaching gunshot detection system to be implemented in Costa Rica. The development of a gunshot detection system is part of an ongoing project started by the Acoustic Ecology Lab at Arizona State University in partnership with the Phoenix Zoo. As a whole, the project entails the development of a gunshot detection algorithm, wireless mesh alert system, device enclosure, and self-sustaining power system. For testing purposes, four devices, with different power system setups, were developed. Future developments are discussed and include further testing, more specialized mounting techniques, and the eventual expansion of the initial device network. This report presents the initial development of the protective enclosure and power system of the anti-poaching system that can be implemented in wildlife sanctuaries around the world.

Description
Two large sectors of water consumption within cities are: city owned irrigated landscape (such as parks) and household consumption. A related, third sector of consumption that has very little research behind it is shared landscapes in residential communities. Neighborhood communities, including those with formal Homeowner’s Associations and informal Neighborhood Associations, have common landscapes they are responsible for up-keeping and irrigating. 208 neighborhood communities exist within the City of Tempe. Each year the city provides $30,000 in grant funding to these 208 neighborhoods to implement water conservation projects. This thesis focuses on ten neighborhoods who had applied and were granted funding to implement a conservation project between the years 2011 and 2016. My findings showed that this program has not been effective in reducing water consumption, wither due to the lack of implementation or the small-scale of the projects. From my research and synthesis, I suggest a layer of accountability be added to the program to ensure projects are effective and participants are implementing their projects and that the program is effective overall. This study provides the City of Tempe with relevant and viable information to aid management of water consumption and conservation within neighborhoods.

Description
Drilling in Section 1002 has been an ongoing debate since the region was designated as a potential area for drilling projects, pending congressional approval in 1980. In 2017, the area was officially opened up for oil and gas development through its passage in the GOP Tax Cuts and Jobs Act of 2017. This act requires 2 lease sales of 400,000 acres, with an allowed 2,000 acre physical footprint (not including pipelines, ice roads, or gravel mines). Using Social-Life Cycle Assessment methodology to assess the process of oil extraction in Section 1002, significant benefits and drawbacks of drilling in this region, with economic, cultural, and social impacts ranging from the local level to the state level to the national level were identified.
Stakeholders impacted by oil development in the Section 1002 region include the Kaktovik community who lives within the Program Area, the Gwich’in people who live south of ANWR, the corporations who will be leasing the land, as well as the employees who will be working on the projects. These stakeholders share similar values and interests, however, when it comes down to the attainment of these values, there are significant differences in opinion. This debate comes down specifically to the desire to ensure stability for one’s family and community, as this means 2 different things to the majority stakeholders on this issue: The Inupiaq and the Gwich’in. The Inupiaq ,who live in Kaktovik specifically ,are particularly keen on the idea of drilling in the Section 1002 region, because the revenues and opportunities that come with the oil and gas development provide access to better standards of living and a more westernized way of life. The Gwich’in, however, value their relationship to the land and the caribou that are at risk of significant change. These 2 groups are critical to the debate, but the state and federal governments have the final say, and a financial incentive to move forward with the lease sales.
Utilizing the S-LCA framework, life cycle impacts of drilling on society are found using indicators that are identified and assessed using both qualitative and quantitative means. Although some conclusions are uncertain due to the forward-looking nature of this S-LCA, the Increasing/Decreasing trends can be identified and confidently attributed to the specific indicators.
Significant Results:
Significant issues this study has highlighted include the resulting impacts, both positive and negative, on the communities affected by oil and gas development in Section 1002. Significant stakeholders include the Kaktovik community, the Gwich’in people, the oil and gas workers in the state of Alaska, and the oil and gas companies themselves. The local residents are the most affected by the impacts of development, with significant issues pertaining to potential for significant lifestyle change, the increased risk of impact on subsistence species, the risks associated with pollution, and the effect on the economy through revenues and job availability.

Description
Woodland/Alloy Casting, Inc. is an aluminum foundry known for providing high-quality molds to their customers in industries such as aviation, electrical, defense, and nuclear power. However, as the company has grown larger during the past three years, they have begun to struggle with the on-time delivery of their orders. Woodland prides itself on their high-grade process that includes core processing, the molding process, cleaning process, and heat-treat process. To create each mold, it has to flow through each part of the system flawlessly. Throughout this process, significant bottlenecks occur that limit the number of molds leaving the system. To combat this issue, this project uses a simulation of the foundry to test how best to schedule their work to optimize the use of their resources. Simulation can be an effective tool when testing for improvements in systems where making changes to the physical system is too expensive. ARENA is a simulation tool that allows for manipulation of resources and process while also allowing both random and selected schedules to be run through the foundry’s production process. By using an ARENA simulation to test different scheduling techniques, the risk of missing production runs is minimized during the experimental period so that many different options can be tested to see how they will affect the production line. In this project, several feasible scheduling techniques are compared in simulation to determine which schedules allow for the highest number of molds to be completed.

Description
As the public becomes increasingly aware of the morality of wildlife institutions like zoos and aquariums, these places are now having to face possible negativity and lack of support from their communities. In light of this, these institutions are now focusing their goals and efforts towards conservation education and outreach programs in order to continue contributing to biodiversity conservation. Research has proven that wildlife institutions like zoos and aquariums are effective ways to teach the community about wildlife and conservation. To measure how effective aquariums are at educating their patrons on conservation, a short survey was administered to 100 patrons of the OdySea Aquarium in Scottsdale, Arizona. The object of the survey was to assess which type of conservation messaging was preferred by the general public and if patrons of the aquarium were likely to engage in pro-conservation behaviors after their visit. It was found that the majority of respondents preferred interactive exhibits as their choice to learn about conservation and wildlife. In addition, almost all respondents agreed that they would continue practicing behaviors that supported pro-conservation actions after their visit to the aquarium. My results also showed that patrons of the aquarium were well educated about plastic pollution and the rehabilitation that OdySea accomplishes for the sea turtles due to their overexpression of mentioning plastic in their open-ended questions. My findings indicate that this aquarium is succeeding in promoting conservation and wildlife education as well as supporting cultivation within their patrons that will benefit the future health of this planet.

Description
White-nose syndrome (WNS) is a fungal infection devastating bat populations throughout eastern North America. WNS is caused by a fungus, Pseudogymnoascus destructans (Pd), that invades the skin of hibernating bats. While there are a number of treatments being researched, there is currently no effective treatment for WNS that is deployed in the field, except a few being tested on a limited scale. Bats have lowered immune function and response during hibernation, which may increase susceptibility to infection during the winter months. Antimicrobial peptides (AMPs) are a crucial component of the innate immune system and serve as barriers against infection. AMPs are constitutively expressed on skin and facilitate wound healing, stimulate other immune responses, and may also stay active on bat skin during hibernation. AMPs are expressed by all tissues, have direct killing abilities against microbes, and are a potential treatment for bats infected with Pd. In this investigation, the fungicidal activity of several readily available commercial AMPs were compared, and killing assay protocols previously investigated by Frasier and Lake were replicated to establish a control trial for use in future killing assays. Another aim of this investigation was to synthesize a bat-derived AMP for use in the killing assay. Sequences of bat-derived AMPs have been identified in bat skin samples obtained from a large geographic sampling of susceptible and resistant species. Contact was made with GenScript Inc., the company from which commercially available AMPs were purchased, to determine the characteristics of peptide sequences needed to synthesize an AMP for lab use. Based on recommendations from GenScript Inc., peptide sequences need to have a hydrophobicity of less than 50% and a sequence length of less than 50 amino acids. These criteria serve as a potential barrier because none of the known bat-derived sequences analyzed satisfy both of these requirements. The final aim of this study was to generate a conceptual model of the immune response molecules activated when bats are exposed to a fungal pathogen such as Pd. Overall, this work investigated sources of variability between trials of the killing assay, analyzed known bat-derived peptide sequences, and generated a conceptual model that will serve as a guideline for identification of immune response molecules on the skin of bats in future proteomics work.

Description
Beginning in 2011, the Gulf of Mexico and all of the surrounding coastlines saw a rapid influx of pelagic Sargassum seaweed. The issue continues to worsen, and as larger amounts of Sargassum continue to wash ashore the affected regions are becoming threatened on multiple fronts. These previously unseen quantities of Sargassum seaweed are creating a host of serious environmental, economic, and health concerns. Affected areas are desperately searching for solutions to help remove the seaweed while wondering if these Sargassum covered beaches will become the new norm. While currently these concerns are centralized in coastal regions of the Gulf of Mexico, there is no evidence that the issue will not proliferate leading to wide-scale global problems. This paper investigates the various concerns created by the inundation of the Sargassum seaweed, researches the unique characteristics of the thriving species of Sargassum in hopes of identifying a solution, and explores the potential market value these solutions may have in an attempt to mitigate the large-scale impact of the Sargassum invasion.
