A Lost Generation: Perpetual Education Insecurity Among The Rohingya, Robin E. Al-Haddad, Kendra L. Duran, Saleh Ahmed

Global Studies Faculty Publications and Presentations

Education security exists when every child has equal access to quality education. Rohingya refugee children suffer widespread rates of education insecurity both in their home country, Myanmar and in their host country, Bangladesh. While the right to education is recognized in several human rights instruments, access to education is not ubiquitous, making the ability to achieve this right challenging for many Rohingya. Government restrictions on accredited education, COVID-19 related school closures, failures in launching a pilot of the Myanmar curriculum, and recent government plans to relocate refugees to Bhasan Char Island have created a ‘lost generation’ of Rohingya youth. This …

Puffins, The Charismatic Clowns Of The Sea: Examining The Relationship Between Community Identity And The Social Construction Of Animals, Megan Henry Tuennerman

Senior Independent Study Theses

This study analyzes the factors, internal and external, that affect the relationship between community identity and the social construction of animals, and the ways in which that social construction impacts the environment. Studied through the lens of the relationship between Atlantic Puffins and the human communities they live near, these questions situate our understanding of human societies as within, as opposed to above, the environment. Without this perspective, enacting environmental protections across the globe is ineffective. The study was conducted using ethnographic methods, including 11 formal interviews with community members and experts, along with observations in Iceland and Canada. Results …

Microplastics As Carrier Of Pahs Released From Oil Spills: Measuring Ingestion And Bioaccumulation Rates In Copepods, Manasi Desai

Senior Independent Study Theses

Microplastics (MP; plastics < 5mm) are a growing problem in the marine environment due to a large influx of plastics entering the marine environment through rivers, wastewater and litter from land. MP are known to adsorb nonpolar compounds in the water including polycyclic aromatic hydrocarbons (PAHs) released from oil spills. In this study, I quantified the ingestion rates of a marine copepod (Calanus finmarchicus) on clean polystyrene MP beads (12 um) and phenanthrene loaded MP beads (0.8 pg PAH pellet -1). I measured the phenanthrene load in copepods ingesting phenanthrene sorbed MPs and copepods exposed to phenanthrene only to measure the role of MP as a vector for PAHs into marine food webs. Additionally, I examined the fecal pellets to check the presence of MPs and if phenanthrene was still adsorbed to them. The results showed that microplastics do not act as vectors as there was no significant difference between the body load of phenanthrene in copepods from ingestion of PAH sorbed MPs and the body load from passive uptake of phenanthrene in solution. Copepods ate significantly lower phenanthrene loaded MP (1.81 x 104 beads cop-1 day-1) than microplastics only (2.67 x 104 beads cop-1 day-1) suggesting that copepods can reject particles based on chemical content. Accumulation of phenanthrene within the copepods (GC-MS analysis) showed individual copepods can accumulate between 3.48 to 4.11 ng of PAH which potentially can biomagnify in the marine food web upon predation. Fecal pellet analysis showed that an average of 2013 MP beads are present with a mean phenanthrene load of 0.15 pg bead-1. For the social science research, I conducted a literature review examining the current Indian plastic waste management strategies, legislations and its implementation. My results find that the Indian government over the years has progressively enacted and amended its policies to try to keep pace with the issue of plastic pollution. However, key challenges in the implementation such as poor enforcement, inadequate training for recycling lack of plastic alternatives and proper waste disposal infrastructure all contribute to the unsuccessful management of waste. Usage of plastic in road construction has shown to be a viable option in reducing plastic waste in India and also improving road conditions.

Re-Imagining Design For Affordable Housing In Mexico, Kenza Fernandez Dominguez

Scripps Senior Theses

Since the presidency of Enrique Peña Nieto, affordable housing developments in Mexico have been produced in a massive, unsustainable scale. The speed at which these developments are produced equates to the carelessness that goes into their planning. At large, the developments’ monotonous design is aesthetically dehumanizing and fails to promote a sense of community. These developments lack basic infrastructure, and their residents have abandoned them, which has incentivized increased criminal activity.

In this paper, I will be looking at successful models of affordable housing globally, exploring the histories of communal living, and function of architectural collages. Based on my findings, …

Where's The Beef? Meat Shortages, Farmer Needs, And Long-Term Recovery Policies In A Pandemic Era, Kim Vu-Dinh

Faculty Scholarship

COVID-19 not only affected every hospital bed in the nation--if not the world; it also affected nearly every dinner table in America and beyond. Supply chain disruptions caused by the pandemic highlighted deep-seated problems with how we get our meat, and how difficult we make it for American farmers to sell to the family next door. Within a few months of the first reported case in the US, hundreds of workers from just two meat-processing plants on American shores became infected with COVID-19, and imports from around the world came to a standstill as factories and shipping companies were forced …
