The Impact Of Remittances On Food Security In Times Of Crisis—Evidence From Covid-19 In Latin America And The Caribbean, Colin Cannonier

Funded Scholarship

This study examines the association between workers’ remittances and food insecurity in Latin America and the Caribbean using data from a Coronavirus survey covering over 100,000 individuals during the COVID-19 pandemic. Results indicate that receipt of remittances is associated with an 8.8% decrease (2.5% points) in overall food insecurity. Heterogeneous effects are observed among females, individuals in Latin America, and households with children. Remittances from the USA exhibit a stronger influence on reducing food insecurity. The findings underscore the potential importance of remittances in improving food security at both extensive and intensive margins. Policy issues are also discussed.

Tanga, Sevgan Subramanian, Daniel M. Mutyambai

All Peer-Reviewed Publications

Plant-parasitic nematodes (PPNs) pose a persistent threat to vegetable production in Kenya, contributing to reduced yields and soil degradation. The management of PPNs in vegetables in Kenya has largely remained unaddressed. The integration of ecological intensification strategies such as the vegetable integrated push-pull (VIPP) system and the use of black soldier fly frass fertilizer (BSFF) is gaining traction in sustainable agriculture. The aim of this study was to determine the effects of integrating VIPP and BSFF on nematode abundance and diversity in maize-kale cropping systems. Field trials were conducted in two different agroecological zones in Kenya. Field treatments involved plots …

No Groundwater, No Fish: The Critical Role Of Groundwater In Supporting Non-Glacial, Salmon-Bearing Rivers In South-Central Alaska, Tyelyn Brigino, Kai Rains, Edgar Guerron-Orejuela, Jacob Argueta, Syverine Bentz, Coowe Walker, Mark Rains

School of Geosciences Faculty and Staff Publications

Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year-round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow. Balancing the needs of users becomes increasingly important as climate change introduces greater uncertainty in water resources and fisheries, especially for economically important anadromous species that depend on freshwater resources. We investigated the seasonal and regional variability of groundwater contributions to six non-glacial mainstem salmon-bearing rivers in south-central Alaska. We hypothesized that groundwater contributes more than half of the annual streamflow, and nearly all …

Poly(A) Probe Hcr Rna-Fish Specifically Marks Pyriform Nurse Cells In The Brown Anole Lizard Ovary, Zoe B Griffin, Bonnie K Kircher, Richard R Behringer

Faculty, Staff and Student Publications

Hybridization chain reaction RNA-fluorescent in situ hybridization (HCR RNA-FISH) is a powerful and increasingly used method for visualizing gene expression in cells and tissues. A probe set against polyadenylated RNA (poly(A)) is often used as a positive control for RNA integrity and staining quality. While optimizing this technique in the ovary of the brown anole lizard (Anolis sagrei), we found that the poly(A) probe produced a strikingly specific and intense signal in pyriform cells, a specialized lizard-specific nurse cell type. This staining pattern was found in both whole-mount samples and paraffin sections, suggesting that poly(A) signal intensity can serve as …

Host Modulation Therapy In Periodontitis: From Established Therapies To Emerging Technologies, Aonjittra Phanrungsuwan, Jiaqi Huang, Neeraja Dharmaraj, Alejandra Cobos Perez, Omid Veiseh, Simon Young, Chun-Teh Lee

Faculty, Staff and Student Publications

Periodontitis is a biofilm-induced chronic inflammatory disease, characterized by gingival inflammation and alveolar bone loss. According to a national survey, approximately half of the U.S. adults are affected by periodontal disease. To effectively prevent and treat periodontitis, it is essential to address its underlying causes. The primary etiological factors include polymicrobial synergy and dysbiosis of the oral microbiota, and a dysregulated immune response. The standard therapeutic approach, mechanical removal of biofilm through debridement, sometimes demonstrates limited efficacy, particularly in cases of severe periodontitis, which may require adjunctive or additional therapy. Emerging evidence indicates that periodontal tissue destruction is initiated by …

Nemolizumab As An Alternative Therapeutic Option For Indolent Systemic Mastocytosis, Sezim Minbaeva, Stephen K Tyring

Faculty, Staff and Student Publications

Indolent systemic mastocytosis (ISM) is a clonal mast cell disorder characterized by recurrent symptoms that can persist despite treatment with antihistamines, leukotriene antagonists, and mast cell stabilizers. Treatment options are limited when symptoms remain refractory, and avapritinib is contraindicated or declined. We describe the case of a 62-year-old female with an 11-year history of ISM who developed worsening pruritus and urticaria despite extensive conservative and biologic therapies, including topical corticosteroids, hydroxyzine, montelukast, omalizumab, and dupilumab. Given her history of stroke, she declined avapritinib. Nemolizumab was initiated with a 60 mg loading dose followed by 30 mg every four weeks. After …

Skeletal Markers: Interpreting Trauma, Healing, And Survival Through Osteological Remains From Medieval Pomerania, Michael Mulliner-Szyndler

Cal Poly Humboldt theses and projects

Traditionally, studies in bioarcheology have cited the presence of individuals with evidence of healed traumatic injuries and certain pathologies as an indication of social care either at the time of the trauma or throughout the individual’s lifetime. Here, I present three case studies of individuals who present with signs of having survived traumatic injuries and related pathologies. These individuals are from a late medieval cemetery in Żelewo, in the historical region of Pomerania in present-day northwestern Poland. The site is associated with the nearby town of Kołbacz, which is home to the oldest Cistercian monastery in Pomerania. This study aims …

The Phenomenon Of Existential Ecumenism In Contemporary Ukraine, Iryna Kondratieva, Andrii Marchenko, Oleksii Marchenko

Occasional Papers on Religion in Eastern Europe

An analysis of existential ecumenism as a dimension of inter-church unity, which is being formed in modern Ukraine due to a common existential threat from the Russian aggressor, when Ukrainian churches unite in an ecumenical response to war crimes, focusing on practical cooperation in real life, on the tasks of social service, and not on existing doctrinal or institutional differences. Existential ecumenism combines the main ideas of existential philosophy, with its emphasis on the value of the human person, the significance of the themes of human freedom and human choice in the face of meaninglessness and death, and ecumenism as …

Detecting Habitat Use Of Three Endemic Freshwater Fish Of Far Southwestern Australia, Paige Rhiannon Wilson

Theses: Doctorates and Masters

The wetland ecosystems of far southwestern Australia face multiple threats including land clearing, historical cattle grazing, changed hydrology, extensive groundwater extraction, and changed fire regimes. Each is exacerbated by a drying climate, and together they provide a significant challenge to the on-going survival of the freshwater fish in this region particularly fish that are endemic, range restricted, and therefore, more likely to be more vulnerable. This study focuses on three such species: Galaxiella munda, Galaxiella nigrostriata and Lepidogalaxias salamandroides, the latter two of which are known to aestivate.

In order to make conservation decisions regarding management of wetlands for …

The Experience Of Homelessness Among Older Adults In Bhutan - A Narrative Inquiry Study, Phuntsho Om

Theses: Doctorates and Masters

A shift in the demographics of homelessness started to occur in the 1900s, with a significant increase in the number of middle-aged or elderly men and women being recognised as a part of the homeless population. The rising urgent global concern of homelessness of older adults necessitates a deeper understanding of the lived experience and holistic well-being of these marginalised adults. This thesis aimed to explore the phenomenon of homelessness of older adults in Bhutan, which is an often neglected topic in both national and international gerontological research.

Employing narrative inquiry within the constructivist approach as articulated by Pino Gravidia …

Lidar-Based Point-Cloud Human Modeling: Pose Estimation, Body-Parts Segmentation, 6g Localization, And Applications, Omar Rinchi

Doctoral Dissertations

"The human body represents a rich source of physiological and behavioral information, where precise analysis of anatomy, body parts, 3D pose, and motion enables cross-disciplinary precision applications. This dissertation formulates this challenge as a human modeling problem, where proposed algorithms convert the human body into a three-dimensional digital twin capturing anatomical structure and pose. These representations are further analyzed using additional algorithms to enable precision applications. To realize this vision, LiDAR sensing is adopted due to its privacy-preserving nature, robustness to lighting conditions, color-blind sensing characteristics, and decreasing cost.

Human modeling using LiDAR is challenging due to sparse, irregular, and …

Reinterpreting Stochastic Optimal Control Under Ecological Uncertainty: Inferring Decision Urgency From Vegetation Biomass Dynamics, Komi Mensah Agboka, Tobias Landmann, Elfatih M. Abdel-Rahman

All Peer-Reviewed Publications

Stochastic optimal control provides a rigorous framework for systems subject to uncertainty, yet its operational use in ecological crisis contexts remains limited by interpretability. We reinterpreted a stochastic control formulation in which selected parameters emerged as indicators of decision urgency rather than normative preferences. Vegetation biomass was modeled as a stochastic stock subject to nonlinear loss driven by feeding pressure (e.g., desert locust activity) and multiplicative noise, with uncertainty represented by a time-varying volatility term that integrated extreme rainfall anomalies and conflict-related disruption. Rather than prescribing an optimal policy, we inverted the closed-form solution of the control problem to infer …

All Peer-Reviewed Publications

The toxicity of fumigant formulations of essential oils (EOs) from curry tree (Murraya koenigii (L.) Spreng (Rutaceae)) against African malaria adult mosquito (Anopheles gambiae sensu stricto (Giles, 1902) (Diptera: Culicidae: Culicini)) was evaluated to identify most effective chemotype of the curry tree against the mosquitoes. Ninety-two compounds (91.78%–96.47% coverage) in the EO profiles were identified, among which EO isolated from curry tree chemotype from Kibwezi was most toxic. This chemotype had a median lethal dose (LD50) of 3.6 × 10⁻³ mg/cm³ (95% CI: 2.70–4.58) and a lethal time (Ti50) of 1.91 ± 0.086 h (p < 0.001). The equivalent LD50 of EOs of chemotypes from Mombasa, Makindu, and Malindi in Kenya was 4.9 × 10⁻³, 6.6 …

Fundamental Rights Betrayed: How Pregnancy Exclusions In Advance Directive Statutes Silence Pregnant People’S Wishes, Molly Hill

Journal of Metals, Materials and Minerals

Bacterial cellulose extracted and purified from Nata de coco was employed as a platform for Cu2+ ion adsorption. 4-vinylbenzyl chloride (VBC) was successfully grafted at the hydroxyl position by using gamma irradiation. The optimum was typically related to VBC concentration of 2% (v/v) and a radiation dose of 50 kGy. FTIR significantly reported the functional group of C-Cl related to VBC. No change of crystallinity and morphology was observed. The thermal decomposition was stable up to 200℃. The modification of branched polyethylenimine (PEI) was prepared in order to change the functionality to N‒H stretching. This was expected to adsorb Cu2+ …

Controlled Release Of Holy Basil Essential Oil Nanoemulsion Encapsulated In Gelatin/ Carboxymethyl Cellulose Hydrogel For Wound Care, Shehbaz Ameer, Pranut Potiyaraj, Tu Minh Tran Vo

Journal of Metals, Materials and Minerals

Holy basil essential oil (HBEO) is a therapeutic agent recognized for its antioxidant, anti-inflammatory, and wound-healing properties. However, its clinical use is limited by poor aqueous solubility, volatility, and instability. Nanoemulsion (NE) is an effective strategy to overcome these limitations. In this study, 1% HBEO in 0.5% polyvinyl alcohol (PVA) aqueous solution formulation yielded nanosized droplets (182±3 nm, PDI = 0.286) and showed sustained release, with 92% drug release over 30 h, compared to the rapid release for 1% HBEO in pure water. To further enhance stability and biocompatibility, the HBEO nanoemulsion (HBEONE) was incorporated into a glutaraldehyde (GA) crosslinked …

Paternal Age Is Associated With Offspring Bone Health—But Not Soft Tissue Composition Or Fracture: The Vitamin D In Pregnancy Study, Mia A. Percival, Kara B. Anderson, Julie A. Pasco, Marc Sim, Sarah M. Hosking, John D. Wark, Natalie K. Hyde

Research outputs 2022 to 2026

Summary: Emerging evidence suggests that paternal health may be associated with offspring later life heath. In this study, advanced paternal age at childbirth was associated with poorer offspring bone mineral density and content at age 11 years. These findings suggest that paternal age may impact childhood musculoskeletal development, warranting further investigation. Introduction: Maternal health during pregnancy is known to impact offspring’s later life health. However, emerging evidence suggests that paternal factors may also be important. Advanced paternal age is associated with poorer offspring outcomes, yet few studies assess musculoskeletal outcomes. This study investigated the association between paternal age at childbirth …
