Vacationing in the City: The Local Impacts of Contemporary Tourism in Three European Cities
Full text linkThis thesis critically analyzes the local impacts of urban tourism in contemporary Venice, Italy, Lisbon, Portugal, and Valencia, Spain. The analysis focuses on the cities’ varying stages of over-tourism crises and hones in on one aspect of tourism’s impacts on each city. Venice serves as a case study of an evident over-tourism crisis with specific consideration for Venice’s economic dependence on tourism. Lisbon acts as an example of an imminent tourism crisis with an emphasis on the social consequences of tourism. Finally, Valencia showcases proactive tourism management as a means to prevent tourism-induced crises altogether, with particular focus on the environmental sustainability opportunities afforded by tourism. This thesis synthesizes news articles, tourism data, resident anecdotes, and scholarly research to construct each destinations’ contemporary analysis. By examining how these cities recognize, measure, and respond to urban tourism’s impacts on their economies, communities, and environments, this thesis highlights the importance of proactive tourism management as a tool to mitigate tourism-induced crises. As European tourism continues to reach unprecedented levels, this thesis’ findings underscore the growing importance of strategic tourism management to mitigate the risks of over-tourism
Scarcity and Economic Decision Making
No full textThose who experience a sense of material scarcity or poverty are oftentimes blamed for making bad financial decisions. This paper finds that the Scarcity Theory, introduced by Sendhil Mullainathan and Eldar Shafir, allows individuals to understand why people in a state of material scarcity make financially harmful decisions. This theory explains that financial scarcity causes individuals to fall into a scarcity mindset, where their cognitive and emotional functions are harmed, and alter their decisions. These “suboptimal” decisions may seem like bad decisions, but oftentimes those in poverty have no other choice but to solve a problem immediately and suffer the consequences of their decisions in the future. These consequences can cause those in poverty to fall victim to poverty traps, which create a cycle of poverty. Although there are negative consequences that come with many of the poor’s decisions, such as taking out payday loans, they are often the only options to survive in a state of scarcity. Government and organizational reform through policies such as cash transfers and more sustainable job designs are necessary to address the cycle of poverty that individuals fall into. Specifically, Universal Basic Income can be implemented to relieve individuals of their scarcity mindsets
Enhancing Culturally Responsive Pedagogy in Teaching and Learning for White Faculty: Can Professional Development Help?
Full text linkPedagogies traditionally used by faculty in U.S. higher education tend to center white students and their success, simultaneously disregarding the learning strengths of BIPOC (Black, Indigenous, and People of Color) students. Culturally Responsive Pedagogy (CRP) may align better with BIPOC students; however, white faculty use of Keywords: culturally responsive pedagogy, professional development, teaching and learning, white racial consciousness CRP is limited and/or superficial. Therefore, professional development for CRP is needed to enhance and deepen the teaching and learning practices of white faculty. Using a multiple case study method, this study examines how white faculty from a diverse range of disciplines understand and enact CRP, focusing on the role of professional development in their CRP practice. Findings demonstrate that a faculty’s context and white racial consciousness impact the effectiveness of CRP-related professional development. This study demonstrates that individual, institutional, and structural beliefs and practices that advance white ways of knowing must be addressed and diminished in order for CRP-related professional development to be effective
Using Motivation Science to Understand and Overcome Common Psychological Barriers to Non-Native Language Learning in Beginner and Intermediate College Courses
Full text linkThis project examined whether established findings from the motivation science literature could be successfully applied to increase non-native language learning outcomes and persistence among college students. Participants were enrolled in beginner and intermediate language courses at a small private college. The study was longitudinal and involved “diagnosing” and immediately implementing interventions to counter deficits experienced by individual students regarding six specific motivational antecedents: expectancies for success, utility value, costs, autonomy, belonging, and growth mindsets. Over the course of a semester, participants’ motivational experiences in these areas were measured and they then completed tailored “just-in-time” intervention activities designed to increase their motivation. The longitudinal aspect of the study allowed us to track general motivational trends experienced by the participants (expectancies, costs, and belonging were relatively constant, while growth mindsets, utility value and autonomy decreased over the semester), and also determine the effectiveness of the individual interventions. Interventions for utility value and autonomy were relatively effective at specific times during the semester, while those for growth mindsets and costs had little effect. Overall, the interventions had short lasting effects, perhaps due to their infrequency and brevity). Additionally, we did not observe significant differences in motivational experiences by gender. Limitations of the study were primarily due to the time constraints, as all aspects of the project needed to be completed in a one-year time frame
How the United States has Failed to Enact Competitive and Stable Energy Policy Through Federalism
Full text linkThis research focuses on the effects of energy policy in the United States. Because of the impacts of energy production and transmissions emissions, energy policy has become synonymous with climate policy. As such, there seems to be two schools of thought regarding energy policy. On the one hand, “green” energy policies have been endorsed for their potential to reduce carbon emissions and dependence on non-renewable resources. On the other, continuing to use legacy energy sources, namely fossil fuels, has been endorsed for its affordability and ease of use through existing infrastructure. At the federal level, green policies have been embraced by liberal leaders, most recently with the Inflation Reduction Act assigning $370 billion to invest in renewable and sustainable energy sources. Pro-fossil fuel policy can be associated with President Trump’s recent litany of Executive Orders which he claims will allow America to “drill baby drill.” States have similarly embraced these two ends of the energy policy spectrum. However, as government control changes, and different governments dispute and challenge one another’s policies, energy policy across the country seems to swing back and forth between these two ends
Tight Spherical Embeddings (Updated Version)
No full textThis is an updated version of the paper [14] which appeared in the proceedings of the 1979 Berlin Colloquium on Global Differential Geometry. This paper contains the original exposition together with some notes by the authors made in 2025 (as indicated in the text) that give references to descriptions of progress made in the field since the time of the original version of the paper. The main result of this paper is that every compact isoparametric hypersurface Mn ⊂ Sn+1 ⊂ Rn+2 is tight, i.e., every non-degenerate linear height function ℓp, p ∈ Sn+1, has the minimum number of critical points on Mn required by the Morse inequalities. Since Mn lies in the sphere Sn+1, this implies that Mn is also taut in Sn+1, i.e., every non-degenerate spherical distance function has the minimum number of critical points on Mn. A second result is that the focal submanifolds of isoparametric hypersurfaces in Sn+1 must also be taut. The proofs of these results are based on Münzner’s [23]–[24] fundamental work on the structure of a family of isoparametric hypersurfaces in a sphere
Looking To the Portrait (Creative)
No full textThis porcelain piece of art displays two women together. One woman holds a bouquet of flowers and seems to be almost comforting her companion, who holds a painting of a man, but at first one’s attention is drawn to the women, rather than the objects they hold. Both women wear powdered wigs and intricate dresses, which appear to be resembling what would be worn in the eighteenth century. Although the women are both dressed in magnificent gowns and objectively are the most eye-catching part of the figure, their attention is drawn to the small painting of the unidentified man. The angle of the camera makes it seem as though the viewer is the third person in this scene, looking on as the woman in blue admires a painting in her handhttps://crossworks.holycross.edu/photographing_antiquity/1083/thumbnail.jp
