the application of deep learning and planning techniques, with the aim of constructing generalized plans capable of solving multiple problem instances. We construct a Deep Neural Network that, given an abstract problem state, predicts both (i) the best action to be taken from that state and (ii) the generalized “role” of the object being manipulated. The neural network was tested on two classical planning domains: the blocks world domain and the logistic domain. Results indicate that neural networks are capable of making such
predictions with high accuracy, indicating a promising new framework for approaching generalized planning problems.
In the story, Awaken, humans contest over territory with the avians — a sentient bid species. Years ago, the humans moved to underground dwellings in order to protect themselves from aerial assaults and developed sophisticated technology to keep the avians away from their crops. Over time, the avains became a legend humans tell their children to get them to behave, but a segment of the government remembers the real threat avians pose and are determined to vanquish their avian enemies. Kial Damian Johnson was created by his mother and father, who are involved in that segment of the government, with avian and human DNA. He finds himself drawn into the continuous battle between avians and humans. He learns that Yellowstone is going to erupt soon and neither avians nor humans can survive without sharing their resources, and he attempts to bring about peace between the two sides.
The narrative deals with issues prevalent in Animal Studies through giving the bird population a voice and a visible culture, and also reflects on current world issues as we strive to work together globally in the Anthropocene. Through researching and conducting interviews, I crafted this story to contribute to the environmental discourse. I wrote this story in a Young Adult style in order to invite the youth to engage in the conversation about issues of cross-cultural environmental sustainability.
As we count down the years remaining before a global climate catastrophe, ever increases the importance of teaching environmental history and fostering environmental stewardship from a young age. In the age of globalization, nothing exists in a vacuum, yet our traditional education system often fails to reflect the abundant connections between content areas that are prevalent outside of schools. In fact, many of the flaws of the field of education have been exacerbated by the COVID-19 pandemic and a forced transition to online schooling, with many educators reverting to outdated practices in a desperate attempt to get students through the year. The aim of this project was to design a unit curriculum with these issues in mind. This month-long environmental history unit engages students through the use of hands-on activities and promotes interdisciplinary connections. The unit can be taught in a physical, online, or hybrid American history class, and will hopefully inspire and motivate students to become environmental stewards as they look toward their futures on this planet.
Drylands, though one of the largest biomes, are also one of the most understudied biomes on the planet. This leaves scientists with limited understanding of unique life forms that have adapted to live in these arid environments. One such life form is the hypolithic microbial community; these are autotrophic cyanobacteria colonies that can be found on the underside of translucent rocks in deserts. With the light that filters through the rock above them, the microbes can photosynthesize and fix carbon from the atmosphere into the soil. In this study I looked at hypolith-like rock distribution in the Namib Desert by using image recognition software. I trained a Mask R-CNN network to detect quartz rock in images from the Gobabeb site. When the method was analyzed using the entire data set, the distribution of rock sizes between the manual annotations and the network predictions was not similar. When evaluating rock sizes smaller than 0.56 cm2 the method showed statistical significance in support of being a promising data collection method. With more training and corrective effort on the network, this method shows promise to be an accurate and novel way to collect data efficiently in dryland research.
Food waste is a crucial issue in stores, restaurants and other institutions. Specifically, there is a high amount of food waste in grocery stores, especially in the produce section. As a result, environmental damage occurs, and many individuals struggle to have food in their homes. This thesis will analyze the cause, quantity, and effect of this waste, and how it can be changed or mitigated. An overarching question was posed to analyze these causes and effects of waste, asking how does the amount of produce waste that occurs in Scottsdale, Arizona contribute to environmental issues and what is being done to remedy this issue? As this is a difficult question to answer on its own, the research was broken down into two more answerable questions, which are Why does produce get wasted in grocery stores? How much of this occurs? and What remedies already exist to limit/reduce this waste? These questions are important because they contribute to knowledge and understanding about food waste, consumer waste, as well as the overall environmental impact of being wasteful. It is also important for both retailers and consumers to understand that waste has an immense and negative impact on the environment and contributes to climate change, and that taking steps to reduce this waste is essential.
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.
