Labour Migrancy And Ethnic Stereotypes: Experiences From Mufindi Tea Plantation, Ca. 1920s To 2000s, Hezron R. Kangalawe

Zamani: A Journal of African Historical Studies

While tea plantations brought good fortunes to some parts of Southern Highlands in Tanzania such as Mufindi and Rungwe during the British mandate, its production sites became centres of ethnic contestations in relation to work discipline. The colonial and post-colonial enterprises labelled some ethnic groups as “reliable labourers” and others “unreliable”. This article, uses the tea plantations in Mufindi district, Iringa, to debate the labour question and ethnic identity in tea plantations between 1920s and 2000s. It argues that tea plantations were practical point of colonial stereotyping whose architects were anthropologists. Interviews in Mufindi tea plantations and factories, archival and …

Collaboration In The Spread Of Missionary Christianity In Africa: The Case Of The Apostolic Church Of Nigeria, Caleb Abiodun Adeleye, Oluwasegun Peter Aluko

Zamani: A Journal of African Historical Studies

This article explores the significance of collaboration in the spread of missionary Christianity in Africa through a historical study of The Apostolic Church of Nigeria (TACN).

In this study, the valorization of sludge as an organic fertilizer for lettuce cultivation was evaluated, offering a sustainable waste-to-resource solution. Sludge from two wastewater treatment plants (Mazouna and El Kerma) were collected between 2019 and 2021. Comprehensive physicochemical analysis was conducted to determine its nutrient value and contaminant levels. In addition, the efficacy and safety of the fertilizer were assessed by measuring lettuce growth and the bioaccumulation of heavy metals in plant tissues. The analyzed sludge, with an organic matter content of 9.91%–83% …

Does Green Electricity Mitigate Carbon Emission Externalities? Industry-Specific Effects On Firm Profitability, Operational Efficiency, Valuation, And Market Risk In Taiwan Listed Companies, Mutiara Eka Puspita, Wei Hwa Pan, Bon Long Hsia, Huynh Phu Tan

Bulletin of Monetary Economics and Banking

his study explores the relationship between carbon emissions and firm financial performance across industries and how green electricity adoption moderates this effect. Using 9,925 firm-year observations from the Taiwan Economic Journal, we estimate panel regressions and compare Fixed Effects robust and Driscoll-Kraay (1998) standard errors to ensure robustness. Two-way and three-way interaction models reveal a green electricity paradox: biotech firms benefit, while financial and high-tech sectors decline. These findings highlight the need for sector-specific ESG investment models and tailored policy support to ensure an equitable green transition. The study contributes by integrating environmental-financial dynamics with industry heterogeneity in emerging markets

Policy Solutions In The Ev Battery Supply Chain Addressing Unethical Social And Environmental Practices, Mateo Mazariego-Halpern

Undergraduate Theses, Capstones, and Recitals

California should adopt a phased supply chain accountability framework for electric vehicles sold in the state, combining the immediate implementation of a voluntary Fair Trade Decal program with the mandatory adoption of COFFEE (Corporate Operations Free From Environmental Evil) Standards based on CAFÉ standards, by 2035. This thesis identifies a critical gap in U.S. EV policy: current federal legislation regulates where batteries are sourced but not how cleanly or ethically they are produced. The consequences of this regulatory gap are severe, with emissions simply shifting further down the supply chain rather than being eliminated, child labor and indigenous displacement going …

The Role Of Urban Forests In Mitigating Flooding Effects: A Case Study In Savannah, Georgia, Gillian Bush

Quantifying Terrain Controls On Satellite-Based Snow Water Equivalent Estimation: A Spatially Explicit Machine Learning Approach, Brant Giovannetti

Geography and the Environment: Graduate Student Capstones

Terrain variables are widely incorporated into machine learning Snow Water Equivalent (SWE) models but are rarely evaluated for their independent contribution relative to spectral predictors. Using a four-tier stepwise Random Forest framework with Harmonized Landsat Sentinel-2 imagery and Airborne Snow Observatory LiDAR ground truth, this study isolates the contribution of elevation, slope, northness, and eastness across Peak and Ablation snowpack regimes in the East Taylor River Watershed, Colorado. During peak snowpack, adding terrain improved R² by 0.214, with elevation alone accounting for 42.8% of model importance. During ablation, full-dataset terrain gains were modest, increasing R² by only 0.036. However, when …

The study employs a qualitative analysis methodology, based on diffusion of innovation theory and conceptual framework, to analyze current policies in Egypt and identify challenges and gaps in their implementation. It also analyzes responses from 23 interviews with experts in the field, manufacturers, dealers, EV …

Beyond Emergency: Charting Pathways To Sustainable Development In Fragile And Conflict-Affected Settings: A Case Study Of Yemen, Sharif Abdurabu Salem Farid Alsahbool

Theses and Dissertations

For nearly a decade, Yemen's eastern governorates of Hadramawt, Shabwah, and Al‑Mahrah have been relatively stable, yet the international aid system has kept delivering short‑term humanitarian relief like food baskets and water trucking instead of shifting to sustainable development that could rebuild people's lives, create jobs, fix infrastructure, and strengthen local government. This thesis investigates why this transition has taken so long. Based on 21 interviews with government officials, international NGO staff, and local NGO managers in these three governorates, the study develops a new way of understanding the problem. It introduces three ideas: the 'emergency mentality', which is a …

Erosion And Accretion: Mobilities Of Sand, People, And Memory At Queer Riis Beach, Jah Elyse Sayers

Dissertations, Theses, and Capstone Projects

The People’s Beach at Jacob Riis Park on the Rockaway Peninsula of Queens, New York, is a vibrant place of queer and trans public-space placemaking—and especially Black and working class queer and trans placemaking. A distinct queer ecology emerges in the interplay of the dynamic movement of the barrier island, queer and trans—especially queer and trans Afro-diasporic—mobilities. This queer ecology, while articulated with, also defies and exceeds logics and workings of private property. In response to a convergence of pressures on Black, queer, trans, and working-class placemaking on the beach site in the 2020s, beachgoers have mobilized longstanding provisional socialities …

Pedagogy Of Care: Exploring Climate Justice Frameworks In Cuny Undergraduate Courses, Ismerlyn Gonzalez

Dissertations, Theses, and Capstone Projects

Climate justice centers the human rights of communities most impacted by the climate crisis rather than solely focusing on the scientific aspects of environmental challenges and disasters. Higher education institutions play a key role in advancing climate justice education, but research shows that frameworks are not consistently defined across institutions. The IRB-approved study that produced the findings in this capstone sought to explore how climate justice frameworks are implemented at the CUNY undergraduate level and learn more about the instructors delivering these courses. From February to April 2026, instructors from different CUNY undergraduate campuses were surveyed, interviewed, and asked to …

Should Dams Respond To Power Prices? Environmental Economics And Emissions Effects Of Hydropower Peaking, Levi Stephen Konrad-Shankland

Environmental Studies Senior Theses

Hydroelectricity stands to be particularly important to a decarbonizing power grid because unlike many renewables it is dispatchable. However, ramping up and down hydropower production at short notice to respond to power demand—hydropeaking—worsens many of the environmental harms of hydroelectricity (Bipa et al., 2024). In Chapter 1, I create a microeconomic framework to explain how and why revenue-motivated dams hydropeak.

In Chapter 2, I assess the extents to which six different case study dams around the US hydropeak, first by decomposing actual flow regime into combinations of counterfactual management objectives, and second with an index of flow variation alignment with …

Urban Sacred Grove: A Visioning For Collective Care, Preservation, Environmental Justice, And Resilience, Oluwadara A. Ojugbele

Dissertations, Theses, and Capstone Projects

My capstone explores how the concept of sacred groves—a community-based practice of conserving forest areas for cultural, spiritual, or religious purposes—can be reimagined as a framework for urban environmental stewardship and community care. Sacred groves have historically varied across time and place but consistently serve as protected spaces that honor divine forces, ancestors, and community values. In the Yoruba context, groves demarcate lush forests as abodes for oriṣas (divine forces) and spiritual beings, often containing shrines and artifacts that embody cultural beliefs. My capstone draws on the sacred grove concept and aims to illustrate how urban communities might adopt sacred …
