Language Play And Racial Dysphemism In The Marrakchi Language Space, Spencer Fausel Jun 2024

Language Play And Racial Dysphemism In The Marrakchi Language Space, Spencer Fausel

Dissertations, Theses, and Capstone Projects

This study seeks to divulge the meaning and popular usage of two phonetically similar yet reportedly distinct dysphemisms spoken and understood in the Marrakchi dialect of Moroccan Arabic (Darija). Darija speakers across the North African lingua-space use the term "qlawi" to denote testicles. In Morocco, speakers utter "qlawi" to express negation or pejorative notions of being, the term commonly wielded to disparage or vituperate a frustrating person or object—drawing connections to the subaltern, the lowly, the destitute, the stupid, the possessionless, and potentially to the racialized (non)object. The word itself can stand as a syntactic substitute for “nothing” in certain …


Socially Racialized And Statistically Invisible: U.S. Census Recognition Of The Middle Eastern And North African Diaspora, Aliana J. Jabbary Jun 2024

Socially Racialized And Statistically Invisible: U.S. Census Recognition Of The Middle Eastern And North African Diaspora, Aliana J. Jabbary

Dissertations, Theses, and Capstone Projects

This thesis delves into the recent decision by the U.S. Executive’s Office of Management and Budget (OMB) to revise the statistical categorization of Middle Eastern and North African (MENA) individuals within federal statistical collection, particularly focusing on the U.S. Decennial Census’ racial and ethnic classifications as outlined in the OMB’s Statistical Policy Directive no. 15. Historically classified solely as racially White, the MENA diaspora’s statistical invisibility within federal data has significant impacts on policy eligibility and access to legal protections, contributing to their social erasure from the national identity. Through a comprehensive analysis of racialization and Orientalism scholarship, alongside an …


Empirical Essays On Retail Investors, Institutional Investors, And Anomalies, Yuqing Yang Jun 2024

Empirical Essays On Retail Investors, Institutional Investors, And Anomalies, Yuqing Yang

Dissertations, Theses, and Capstone Projects

This dissertation consists of five chapters on market efficiencies through retail and international mutual fund investors.

Chapter 1 This chapter briefly introduces this dissertation.

Chapter 2 This chapter Anomalies Never Disappeared: The Case of Stubborn Retail Investors delves into the “stubborn” retail investors and finds that anomalies traded against by retail investors never disappear in the long run, defying the conventional wisdom that anomalies are disappearing in recent years as market efficiency improves. Incorporating retail trading, I develop asset pricing models that surpass existing prominent models in explaining these long-run alphas. I hypothesize that retail investors exacerbate anomalies: the more …


The Mazdakites, The ʿAyyārs And The Mithraists, Parvaneh Pourshariati Apr 2024

The Mazdakites, The ʿAyyārs And The Mithraists, Parvaneh Pourshariati

Publications and Research

No revolutionary movement in Iranian Late Antiquity has attracted as much attention as the fascinating and enigmatic Mazdakite uprising of the late fifth century. The scholarly consensus about these has it that 1) they engaged in ibāḥat al-nisā, sharing of wives; 2) advocated the sharing of property and 3) that their past time was wine imbibing and merrymaking. I shall argue here that, as Shaki correctly suspected but did not pursue the topic, the description of the Mazdakite in our primary sources (the Letter of Tansar, Ibn Qutayba, Ṭabarī, Dīnkard, Shahrestānī), actually follows the praxis of the ʿayyārs, chivalrous men …


A Pearl Ravaged: The Paradox Of Haiti And Its Socioeconomic Origins, Isabel Ishibe Exel Feb 2024

A Pearl Ravaged: The Paradox Of Haiti And Its Socioeconomic Origins, Isabel Ishibe Exel

Dissertations, Theses, and Capstone Projects

Saint-Domingue was once the most profitable colony of the Caribbean, the so-called pearl of the Antilles. Nowadays, Haiti is known for being the poorest country in the Western Hemisphere, a dramatic shift that raises the question of the factors contributing to Haiti's current state, marked by persistent violence, natural disasters, and political instability. Various discourses have framed Haiti as a country doomed for failure. However, relying on binary concepts such as success and failure is counterproductive to a refined analysis. How, then, should we structure this conversation? My ultimate goal for this work is to provide a nuanced analysis of …


Containerization Of Seafarers In The International Shipping Industry: Contemporary Seamanship, Maritime Social Infrastructures, And Mobility Politics Of Global Logistics, Liang Wu Feb 2024

Containerization Of Seafarers In The International Shipping Industry: Contemporary Seamanship, Maritime Social Infrastructures, And Mobility Politics Of Global Logistics, Liang Wu

Dissertations, Theses, and Capstone Projects

This dissertation discusses the mobility politics of container shipping and argues that technological development, political-economic order, and social infrastructure co-produce one another. Containerization, the use of standardized containers to carry cargo across modes of transportation that is said to have revolutionized and globalized international trade since the late 1950s, has served to expand and extend the power of international coalitions of states and corporations to control the movements of commodities (shipments) and labor (seafarers). The advent and development of containerization was driven by a sociotechnical imaginary and international social contract of seamless shipping and cargo flows. In practice, this liberal, …


Climate Change And Critical Agrarian Studies, Ian Scoones, Saturnino M. Borras Jr., Amita Baviskar, Marc Edelman, Nancy Peluso, Wendy Wolford Jan 2024

Climate Change And Critical Agrarian Studies, Ian Scoones, Saturnino M. Borras Jr., Amita Baviskar, Marc Edelman, Nancy Peluso, Wendy Wolford

Publications and Research

Climate change is perhaps the greatest threat to humanity today and plays out as a cruel engine of myriad forms of injustice, violence and destruction. The effects of climate change from human-made emissions of greenhouse gases are devastating and accelerating; yet are uncertain and uneven both in terms of geography and socio-economic impacts. Emerging from the dynamics of capitalism since the industrial revolution — as well as industrialisation under state-led socialism — the consequences of climate change are especially profound for the countryside and its inhabitants. The book interrogates the narratives and strategies that frame climate change and examines the …


Globalization And Transnational Organized Crime: Family Disintegration In Africa And The Impact On Women And Girls, Oluremi Alapo Jun 2023

Globalization And Transnational Organized Crime: Family Disintegration In Africa And The Impact On Women And Girls, Oluremi Alapo

Open Educational Resources

Documented incidents of trafficking in women and children in West Africa date as far back as the 1960s. Significant public recognition and focus only happened around the 1990s. Although no exact figures and data on the number of trafficked victims, there are indicators to show that the incident in the sub-region is reaching alarming proportions. One of such indicators is the growing number of women and children, especially children in cities and big towns of West African states and European countries who are in these places as a result of urban and illegal transborder migration as well as a growing …


Understanding The Afghan Diaspora: Exploring The Factors Driving Migration And The Impact Of Migration Policies On Recent Afghan Evacuees Resettling In The United States, Aya H. Mohamed Jun 2023

Understanding The Afghan Diaspora: Exploring The Factors Driving Migration And The Impact Of Migration Policies On Recent Afghan Evacuees Resettling In The United States, Aya H. Mohamed

Dissertations, Theses, and Capstone Projects

Afghanistan has been at war with the West since the late 1900’s, remaining in a state of constant turmoil. During the Cold War (1979), Afghanistan had fought a war with the Soviet Union, known as the Soviet- Afghan War. During this time, Afghanistan was invaded by both the Soviet and US, creating a ground for terrorism and the rise of the Taliban in Afghanistan. In order to then eradicate the terrorist regime, the Taliban, the United States went to war with Afghanistan in 2001. The Taliban were suppressed by U.S. forces until August 2021, during which President Biden executed a …


Obesity Risk And Comorbidities Among Colombians In New York City And In Colombia, Carlos A. Devia May 2023

Obesity Risk And Comorbidities Among Colombians In New York City And In Colombia, Carlos A. Devia

Dissertations and Theses

Introduction: The prevalence of obesity and overweight in adults and children continues to increase worldwide, accounting for the mortality and morbidity from several diseases. Obesity disproportionally impacts Latinos in the United States (U.S.), and despite their diversity in origins, ancestry, and culture, it is still unclear the burden of obesity by specific Latino groups. For example, little information is available about how obesity impacts Colombians in the U.S. (the largest South American population). New evidence also indicates that Latino immigrants may no longer be arriving with healthy weight status to the U.S. because Latin American countries are undergoing epidemiologic and …

Diasporic Women’S Mutability In South Asian Postcolonial Literature, Tasnim S. Halim May 2023

Diasporic Women’S Mutability In South Asian Postcolonial Literature, Tasnim S. Halim

Theses and Dissertations

Though Western scholarship tends to homogenize South Asian experiences, researchers and novelists shed light on different classes of South Asian postcolonial and migratory women who experience mutability, or the internal and external changes as a trauma response after British colonial rule ended and the 1947 Partition abruptly fractured national identity. Though this mutability has positive and negative transformative qualities, it also allows women characters the power to remove themselves from cycles of oppression, work towards healing, and transforming their physical bodies from sites of repressed trauma to sites of expression and agency. What binds them is not only their physical …

The Origins Of The Iraq War: The Role Of Anthrax In The Weapons Of Mass Destruction Claims, John P. Koenig May 2023

The Origins Of The Iraq War: The Role Of Anthrax In The Weapons Of Mass Destruction Claims, John P. Koenig

Student Theses and Dissertations

The 2001 Anthrax Attacks were a critical factor in the Weapons of Mass Destruction (WMD) claims that sparked the Iraq War. Despite its significance, little systematic work has been done regarding the topic. Existing studies primarily focus on the role of the Military Industrial Complex and intelligence failures as the primary explanations for the origins of the Iraq War. These explanations are limited, as they rely on hindsight biases. This thesis contends that anthrax was the catalyst for WMD claims that sparked the Iraq War. The 2001 Anthrax Attacks reinforced the belief that Iraq harbored WMDs and posed a threat …


David Versus Goliath: The Power Of Weakness In Asymmetric Warfare—Lessons From History, Nicholas K. Petaludis Feb 2023

David Versus Goliath: The Power Of Weakness In Asymmetric Warfare—Lessons From History, Nicholas K. Petaludis

Dissertations, Theses, and Capstone Projects

Under what conditions do violent nonstate actors (VNA) succeed against states? Why does David sometimes beat Goliath? Since at least the time of Thucydides and the Peloponnesian Wars, the realist narrative in international relations measures power primarily in relative, coercive, and deterrent terms. Strong states should accordingly face fewer constraints and enjoy more options while pursuing their national interests. Unconventional warfare, and its subsets of terrorism and insurgency, should—given these circumstances, end in VNA failure. Sometimes, however, VNAs find success. By comparing the literature on historical and current case studies, I propose that a set of preconditions and two mechanisms …


The Bracero Program And The Exploitability Of Migrant Workers, Kayla E. Dantona Feb 2023

The Bracero Program And The Exploitability Of Migrant Workers, Kayla E. Dantona

Dissertations, Theses, and Capstone Projects

This thesis explores the exploitability of migrants working in the United States. Historically, the United States government has emphasized the economic utility of migrant workers, while ignoring their basic human rights. Policymakers have viewed these people as a disposable work force and seek to control them by generating widespread fear of deportation, racialized segregation, discriminatory treatment, and with the help of governing and policing entities willing to turn a blind eye to these injustices, as long as they continue to profit financially.

This thesis will look at the Bracero Program with a historic lens to exemplify the system of exploitation …


Civil Society Organizations Serving Children In Vietnam: Opportunities And Constraints Working With Government Agencies, Trang P. Kelly Feb 2023

Civil Society Organizations Serving Children In Vietnam: Opportunities And Constraints Working With Government Agencies, Trang P. Kelly

Dissertations, Theses, and Capstone Projects

When Vietnamese civil society organization (CSO) administrators manage their relationships with government authorities to ensure children receive social services, they operate under Vietnam’s complex political, socioeconomic, and cultural constraints in environments where the Vietnamese government employs soft power to control CSOs and their donors. This study adds to the literature on the nature of CSO in Vietnam. It details the current imbalance of power between state-sponsored organizations (SSOs) and non-SSOs and provides an updated view of how Vietnamese non-SSOs mix social, economic, and political roles as employers and advocates.

Combining a qualitative exploratory and interpretative case study, I address a …

Water is a fundamental need of all living things. The right to clean water is classified as a human right under United Nations Resolution 64/292.As such it is the responsibility of governments to ensure its citizens are not deprived of this essential resource.

This thesis explores the water management efforts of Pakistan and India. These countries are facing a water crisis, whereby numerous citizens have died due to dehydration and diseases contracted …


Non-Governmental Organizations And The Implementation Of The Convention On The Elimination Of All Forms Of Discrimination Against Women In Uzbekistan, Sayyora Khaydarova Jan 2023

Non-Governmental Organizations And The Implementation Of The Convention On The Elimination Of All Forms Of Discrimination Against Women In Uzbekistan, Sayyora Khaydarova

Dissertations and Theses

The Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) is a landmark international treaty aimed at promoting and protecting women's rights globally. Its implementation is monitored by a Committee of experts which, in so doing, relies extensively on the active engagement of non-governmental organizations (NGOs). The purpose of this thesis is to highlight the role of NGOs in contributing to the implementation of norms of CEDAW in Uzbekistan. Thanks to their symbiotic relationship with governmental authorities and the Committee and as shadow reporters, information providers and advocates NGOs have significantly contributed to the country's noticeable but …

Dissertations and Theses

This study assesses the extent to which indigenous peoples have been included in the National Determined Contributions (NDCs) of four Latin American countries: Costa Rica, Colombia, Ecuador and Bolivia. By examining the consequences of their exclusion, the study highlights the political marginalization of indigenous peoples. In addition, the study explores avenues for voicing indigenous concerns through regional organizations such as the Organization of American States (OAS) and the Inter-American Court of Human Rights (ICHR). By identifying lessons for Latin American states and advocating for regional cooperation, the research aims to strengthen the position of indigenous peoples in international climate negotiations …

Countering Dispossession: For Palestinians In The Diaspora, Maintaining Cultural Identity Is A Means Of Resistance, Reem Farhat Dec 2022

Countering Dispossession: For Palestinians In The Diaspora, Maintaining Cultural Identity Is A Means Of Resistance, Reem Farhat

Capstones

For decades, Palestinians have pushed back against Israeli appropriation of Palestinian culture, by calling it out online and making efforts to protect it through international organizations. On social media, Palestinians in the diaspora have resisted against erasure and appropriation of their heritage by learning, sharing, and teaching others about their culture online. Chef Nadia Gilbert, embroidery artist Asma Barakat, and TikToker Serena Rasoul have all maintained online presences dedicated to educating their followers on Palestinian culture. To them, practicing these aspects of their heritage in the diaspora is a means of resistance.
