The Impact Of Sustainable Responsible Investment On The Environmental And Financial Performance Of Listed Companies (In The Context Of European Regulatory Framework), Leila Kamara

Engaged Management ReView

Although socially responsible investment (SRI) first emerged in the United States in the 1970s, its influence is now global and booming. The most striking illustration is the increase of signatories to the United Nations Principles for Responsible Investment (PRI): The number of signatories surged from around 100 in 2006 to more than 5,000 in 2025 (Peillex & Comyns, 2020), confirming that SRI is now central to investment strategies. The landscape of environmental, social, and governance (ESG) investment has seen the emergence of new stakeholders, including data providers. However, persistent limitations regarding data transparency, accessibility, and comparability have prevented investors from …

Ecological Restoration Strategies Based On Plant And Soil Characteristics For Dumps Of Surface Coal Mines In Cold Arid Regions, Wang Hao, Li Haichao, Jiang Xinjun, Cao Shumiao, Yang Fan, Wang Qiangmin, Xu Ganggang, Shi Hui

Coal Geology & Exploration

Objective The dumps of surface coal mines in cold arid regions represent ecologically vulnerable areas formed under extreme disturbance. However, a lack of systematic studies on the vegetation and soils in dumps, including their spatial variation patterns and synergistic mechanisms caused by vertical differences of the dumps, leads to insufficient theoretical bases for formulating differential ecological restoration strategies in engineering practice.Methods By integrating field ecological surveys and physicochemical tests in the laboratory, this study investigated the dump with elevations ranging from 2498 m-2632 m of the Heishan coal mine on the northern slope of the Tianshan Mountains, Xinjiang. Based …

Distinguishing Drought Experiences: From Perception To Measurement And Their Significance On Productivity Value In Uganda, Parisa Pakrooh, Fabio Gaetano Santeramo, Giuseppe Maggio

Fondazione Eni Enrico Mattei Working Papers

Weather shocks increasingly threaten agricultural productivity in Sub-Saharan Africa. While the negative effects of drought on production have been documented in numerous studies, the behavioral dimension of adaptation, particularly how households perceive drought and what shapes these perceptions, remains less explored. The study focuses on Uganda to distinguish between self-reported drought (subjective) and data-driven drought (objective) and how their divergence is associated with agricultural outcomes. The study relies on four waves of household surveys (UNPS for 2009/10, 2010/11, 2011/12, and 2013/14) with historical re-analysis data on temperature and precipitation from 1981 to 2015. Log-linear and logit models are applied to …

Injectable, In Situ Forming Peptide Nanofiber Reinforced Composite Hydrogels For Age-Related Macular Degeneration, Shambhavi Bagewadi Ms

Theses and Dissertations

Cell therapy for age-related macular degeneration (AMD) is limited by the absence of a functional substrate such as Bruch’s membrane (BM), which is critical for retinal pigment epithelial (RPE) cell survival and integration. Although preformed substrates have been explored, their implantation can disrupt the fragile retinal architecture, compromise ocular immune privilege and increase infection risk. To address these limitations, an injectable hydrogel capable of forming in situ was developed. The hydrogel consists of thiol-modified hyaluronic acid (HA-SH) and polyvinyl alcohol (PVA). Peptide nanofibers were incorporated to enhance structural reinforcement. Three self-assembling peptides - RADA-16, GAGA and GAGA-YIGSR were designed and …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Wet tropical forests are experiencing rising temperatures and increased frequency and intensity of extreme climatic events, such as cyclones, which can increase rates of soil erosion and surface runoff. Fungal litter mats, formed by agaric decomposer fungi, play a crucial role in stabilizing slopes, preventing erosion, and aiding nutrient cycling; however, little is known about how warming affects litter mat growth and function. We investigated two litter mat-forming fungi, Gymnopus johnstonii and Marasmius aff. crinis-equi, in warmed (+4°C above ambient) and control plots in the Luquillo Experimental Forest, Puerto Rico. Growth and time-to-leaf colonization were monitored over 6 weeks …

Improving Nursing Compliance With Pressure Injury Prevention In Postoperative Patients In The Cardiovascular Intensive Care Unit, Chingyi Lam

Spatial Analysis Of Maize Yields And Household Dietary Diversity In Sub-Saharan Africa: Causal Evidence From A Machine Learning Instrument, Addi Joof

Master's Theses

MAIZE YIELDS AND HOUSEHOLD DIETARY DIVERSITY IN SUB-SAHARAN AFRICA: EVIDENCE ON THE CAUSAL EFFECT FROM A MACHINE LEARNING INSTRUMENT

Addi Joof, University of San Francisco, May 2026

This paper provides estimates of the effect of maize yield on household dietary diversity across seven Sub-Saharan African countries, using data from 36,474 maize-growing households in the Living Standards Measurement Study Integrated Surveys on Agriculture (LSMS-ISA) panels for the period 2008--2021. OLS estimates which include district and country-by-wave fixed effects yield a positive and significant coefficient of 0.070 (SE = 0.006, p < 0.001), implying that a 10 percent increase in maize yield raises the Household Dietary Diversity Score (HDDS) by approximately 0.007 food groups. Because self-reported yields are subject to classical measurement error and unobserved household characteristics confound the OLS estimate, we construct an instrumental variable using a Random Forest model trained on satellite-derived agro-environmental features including the Enhanced Vegetation Index, Normalized Difference Vegetation Index, Growing Degree Days, precipitation, and soil moisture obtained from Google Earth Engine at the GPS-coordinate-by-year level. Our preferred 2SLS specification, which adds region fixed effects to absorb persistent sub-national geographic variation, returns a positive point estimate of 0.217 (SE = 0.206; 95% CI: -0.19 to +0.63, p = 0.294) larger than OLS and consistent with downward attenuation bias, but imprecisely estimated and statistically indistinguishable from zero at conventional levels. We interpret the OLS estimate of 0.070 as a credible lower bound on the true effect, with the IV evidence pointing to a moderately larger but uncertain magnitude. Heterogeneity analysis reveals a declining gradient across consumption quintiles the effect is strongest among the poorest households (Q1: 0.055, p < 0.01) and diminishes with wealth (Q5: 0.015, not significant) while showing no gradient across market-integration levels. These patterns are consistent with own-consumption, rather than market income from surplus sales, as the primary pathway from yield to dietary diversity. OLS estimates are positive and significant in five of six estimable countries. The findings suggest that maize yield improvements can serve as a nutrition co-investment, particularly for subsistence-oriented smallholders, though the available data do not permit a sharp causal quantification of the effect size.

Linking Fishery Productivity To Child Health In The Coastal Tropics, Francisco Flores-Mejia

Master's Theses

Fish are a primary source of calories, macronutrients, and income for coastal communities around the world, but overfishing and environmental changes have dramatically reduced productivity in the majority of small-scale fisheries. The social costs of these losses are believed to be large, particularly in poorer communities, but most estimates of fishery productivity effects on households are contextual and difficult to generalize. We combine a remote sensing measure of pelagic fishery productivity with geolocated child health and growth data from 34 countries in the coastal tropics. We estimate that the difference between sustainedly good versus bad fishing conditions corresponds up to …

Herd Conditions And Food Security: Evidence From Kenya, Kira J. Enriquez

Master's Theses

Food insecurity is worsening across Kenya's Arid and Semi-Arid Lands, where over three million people currently face acute hunger. Among pastoral communities in these regions, livestock are the central productive asset and primary food source. When herds deteriorate, households face falling milk production and the erosion of assets that would otherwise buffer consumption during difficult periods. This paper tests whether livestock body condition and rangeland forage quality predict household food coping behavior, and whether those relationships differ above and below a Micawber-style herd size threshold. Using a panel of 232 pastoralist households surveyed across five ASAL counties between 2021 and …

Examining The Ligands, Location, And Function Of Toll-Like Receptor 10, Kiefer Keanu Tam

Master's Theses

Toll-like receptors are a class of innate immune pattern recognition receptors that detect pathogen-associated molecular patterns and regulate downstream inflammatory responses. Toll-like receptor 10 remains the only human TLR whose ligand specificity, cellular localization, and immunological function are not fully defined. Emerging evidence suggests that TLR10 may play an anti-inflammatory role and can heterodimerize with TLR2 to modulate immune signaling. Previous studies from our laboratory demonstrated that stimulation with heat-killed Mycobacterium tuberculosis promotes TLR2-TLR10 heterodimerization and trafficking to the cell surface. In this study, we expanded our ligand panel to include additional gram-positive bacteria, particularly anti-inflammatory probiotic species, to further …

Kicau Kericau: The Chirps And Warbles Of A Bird-Human Story, Airien Ludin

Masters Theses

This thesis tells the tale of bird-human relationships and what it means to live alongside one another, subverting the hierarchical view of humans as above birds inherited from colonial history. It asks how the practice of illustration can function as a site of Two-Eyed Seeing, where scientific and local knowledge are held together as an entangled narrative. It also examines how mendongeng (storytelling), as I have experienced it within Indonesian culture and everyday contexts, can help us understand birds as a companion species with their own agency.

The Parent Phone Use Regulation Efficacy Scale (P-Pure): Initial Validation And Associations With Problematic Smartphone Use, Self-Regulation, Impulsivity, Mindfulness, And Self-Efficacy, Brandon T. Mcdaniel, Sabrina Uva, Adam M. Galovan

Health Services and Informatics Research

Parents often rely on smartphones in daily life. While smartphones offer benefits, they also present challenges, such as potential distraction and delayed responsiveness. It is also possible that problematic smartphone habits may develop, such as repeated checking or difficulty controlling use. Furthermore, self-efficacy around regulating one’s phone use is tied to the ability to change, meaning self-efficacy could be a key mechanism impacting the effectiveness of interventions regarding problematic phone use. Thus, we developed and explored the validity of the Parent Phone Use Regulation Efficacy Scale (P-PURE) to assess parents’ self-efficacy in managing phone use around their children. We developed …

Slouching Towards Inefficiency? The Cardiometabolic And Cognitive Costs Of Poor Posture, Ava Mae Fitzenrider

Honors Projects

Posture affects all of our lives. It is both static and dynamic, adapting continuously to environmental demands. One postural alteration frequently observed in occupational settings is hyperkyphosis, which can be induced by sitting position. During computer use, individuals commonly adopt a slouched posture, which can exacerbate hyperkyphosis, and contribute to dis-ease within the body. Previous research has demonstrated that such postural deviations can negatively affect pulmonary function, as well as other bodily functions. Despite these findings, the effects of acute hyperkyphosis (“slouching”) on cardiometabolic function and cognition remain largely unexplored. Therefore, the purpose of this study was to examine the …

Soft Power, Arab Media And Sports Mega Events: Coverage Of Fifa 2022 And Lessons For Future Arab Hosting, Lynne Kennedy, Maaira Shahbaz, Ala Al Rajabi

All Works

Sport mega-events (SMEs) increasingly transcend athletic competition, functioning as strategic instruments for national identity formation, statecraft, and soft power projection. This dynamic is particularly pronounced in the Gulf, where Qatar’s successful hosting reignited regional rivalries and attracted unprecedented global scrutiny. While existing scholars have extensively examined Western media portrayals of SMEs, a notable gap remains for academic engagement with Gulf media. Dismissed as state-controlled and analytically lacking, we contend that such media offer a rich site for exploring how small states use media as soft power, to construct and contest legitimacy, identity, and global influence. This analysis suggests how state-aligned …

Peninsula Medical School

This seminar addresses the complexity of the management of epilepsy in adults with intellectual development disorders (IDD), advocating holistic and multidisciplinary care aligned with the learning objectives of the International League Against Epilepsy. Epilepsy is significantly more prevalent in people with IDD, presenting unique diagnostic, therapeutic, and psychosocial challenges. Accurate diagnosis is hampered by limitations in communication, necessitating reliance on caregivers' observations. In adults with IDD and epilepsy, utilization of diagnostic tools, e.g., video electroencephalograph (EEG) monitoring, is helpful but can be challenging. Management requires careful consideration of cognitive and behavioral comorbidities and the effects of antiseizure medications (ASMs) on …
