All Rsif Scholars' Publications

This study aimed to evaluate the role of trees outside forests on agricultural land (TOF‑AL) in preserving the initial aboveground biomass (AGB) of forests within the agricultural landscape of Mongala province in the Democratic Republic of Congo. In 2024, tree inventories were conducted over four months in the forests and agricultural lands of Mongala province to analyse AGB. The effects of artisanal logging and charcoal production activities on the AGB conservation rate were considered. This study indicates that 78.3% of the trees encountered in agricultural lands were large‑diameter trees (diameter at breast height (DBH) ≥ 60 cm). In forest areas, …

Effect Of Aflasafe Tz01® On Aflatoxin Reduction And Emerging Challenges With Fusarium Mycotoxins In Maize From Rural Tanzania, Sambwe Fundikira, Martin Kimanya, Rashid Suleiman, Marthe De Boevre, Kokeb Tesfamariam Kokeb Tesfamariam, Sarah De Saeger

All Rsif Scholars' Publications

Aflatoxins are carcinogenic secondary metabolites produced by Aspergillus species and are common contaminants of many crops including maize. Atoxigenic Aspergillus flavus strains, formulated as biocontrol products such as Aflasafe® TZ01, that comprises a mixture of four native atoxigenic strains, are used as pre-harvest agents to suppress toxigenic strains and reduce aflatoxin levels. This study assessed the intended and potential unintended impacts of Aflasafe® TZ01 on mycotoxin contamination in maize. A total of 158 samples 79 from treated and 79 from untreated fields were collected from Chemba and Kiteto districts in Tanzania. Multi-mycotoxin analysis was conducted using liquid chromatography coupled with …

Brucellosis is a neglected zoonotic disease in most developing countries, including South Sudan. Precise identification of Brucella species is crucial for addressing public health and epidemiological concerns associated with brucellosis. The study aimed to identify Brucella species using real-time polymerase chain reaction (qPCR) from seropositive samples that were acquired from an earlier investigation. A total of 143 genomic DNA samples were extracted from brucellosis Rose Bengal plate test (RBPT) seropositive samples from humans (n=7), cattle (n=103) and goats (n=33). The samples were collected from Terekeka and Juba counties, Central Equatoria State (CES), South Sudan. The qPCR targeting the Brucella-specific IS711 …

Jstmapp: A Web-Based Joint Spatiotemporal Modelling And Mapping Application For Epidemiologists, Alfred Ngwira, Samuel O.M Manda, Esron D. Karimuribo, Sharadhuli I. Kimera

All Rsif Scholars' Publications

Disease mapping models help create disease risk maps, which public health policymakers can use to design disease control and monitoring programmes. These models are now routinely implemented using spatial statistical software packages that use frequentist estimation methods, such as SaTScan and HDSpatialScan, and Bayesian estimation methods, such as the Windows version of Bayesian inference using Gibbs sampling (WinBUGS) and R integrated nested Laplace approximation (INLA). We aimed to develop a user-friendly joint disease spatiotemporal modelling and mapping application (JSTMapp) for epidemiologists and health statistics analysts based on Bayesian methods. Using the R package Shiny and utilising the proven and embedded …

Effect Of Malt Barley Cluster Farming On Food Security In Amhara Region, Ethiopia, Betelhem Tsedalu Adane, Irene Susan Egyir, Ama Asantewah Ahene-Codjoe, Taeyoon Kim

All Rsif Scholars' Publications

Cluster farming is the practice of merging neighbouring farms into a unified production unit to grow specific crops collaboratively. This is a promising method to enhance food security by improving agricultural productivity through coordinated resource use and enabling access to inputs, technologies, and markets. Despite this benefit, no empirical studies have examined how malt barley cluster farming affects smallholder farmers’ food security. This study adopts descriptive and econometric analysis, including the endogenous switching regression model (ESRM) and control function approach to account for selection bias and endogeneity in estimating the causal effect of malt barley cluster farming. Cross-sectional data were …

Sarcoidosis With Isolated Osseous Manifestations Mimicking Metastatic Malignancy, Ahmed Ismail, Ahmed Saleh, Yanis Boumber

Department of Medicine Faculty Publications

Sarcoidosis is an inflammatory disease of unknown etiology that commonly involves multiple organ systems, with the lungs and lymph nodes most frequently affected. Osseous involvement, although recognized, is considered uncommon and often overlooked due to its nonspecific clinical and radiographic features. Patients may be asymptomatic or present with pain, swelling, and functional limitations of the affected limb. Imaging can reveal findings such as bone lesions that mimic malignancy, including lytic or sclerotic changes. Diagnosis relies on histopathological confirmation of non-caseating granulomas. Treatment is directed at symptom relief and preservation of limb function. Here, we present a rare case of isolated …

The guidance also addresses the challenges of maintaining …

It’S Time To Stop Calling People "Stakeholders", Bethann Garramon Merkle, Evelyn Valdez-Ward, Priya Shukla, Skylar R. Bayer

Human–Wildlife Interactions

Although the term “stakeholder” has been widely used in science communication, recent expansion in the discourse around the negative connotations of the term necessitate that scientists and practitioners cease using the term. We discuss why this shift is necessary, how it affects our own praxis, and suggest resources for working through more respectful and just language. Looking to the science communication literature can help recalibrate terminology in positive ways.

Habitat Loss And Its Behavioral Effects On A Female Gray Hawk In The Lower Rio Grande Valley Of Texas, Usa, Michael T. Stewart, Ashley M. Tanner, Brian A. Millsap, William S. Clark

Human–Wildlife Interactions

Habitat loss is a major threat to wildlife worldwide. While habitat loss is commonly associated with the fragmentation, degradation, or destruction of large tracts of suitable space, habitat loss in urban environments can be much more incremental and nuanced. We tracked an adult female gray hawk (Buteo plagiatus) in the Lower Rio Grande Valley of Texas, USA, before and after 70% of the trees (7.6 ha) were cleared from the core of the nesting territory. While the hawk’s overall activity budget between within-patch and exploratory movements was unchanged, the hawk undertook substantially longer exploratory movements after the trees …

Evaluating Lethal Coyote Management In The Chicago Metropolitan Area Using A Conflict Recurrence Metric, Jeffrey T. Schultz, Scott Beckerman, Robert Erickson, Danielle Montgomery, Stewart W. Breck

Human–Wildlife Interactions

Human–coyote (Canis latrans) conflict in urban environments is prevalent in cities throughout the United States. Urban areas commonly use nonlethal techniques to mitigate coyote-caused conflicts but will also incorporate selective removal of individual coyotes when conflicts persist. However, little research has evaluated these management strategies. This study analyzed coyote removal efforts conducted in the Chicago Metropolitan Area from 2010 to 2020. To evaluate the management actions, we used “time without incidence”—the time elapsing from an initial conflict until either a subsequent conflict occurred in the same area, or when the data collection period ended—as an index of effectiveness. …

Use Of Scat Dna To Estimate Coyote Abundance On A Newly Colonized Barrier Island, Sonia M. Hernandez, Michael J. Yabsley, Sarah C. Webster, Elizabeth M. Kierepka, Rochelle R. Beasley, Carly L. Landa, Heather W. Barron, Kelly Sloan, Holly Milbrandt, James C. Beasley

Human–Wildlife Interactions

Coyotes (Canis latrans) have expanded in mainland eastern North America and are known to have successfully colonized numerous islands. However, there are scarce data on the densities of coyotes in these ecosystems, in which coyotes can have substantive negative impacts. Coyotes first colonized Sanibel Island, a barrier island off the western coast of Florida, USA, in 2011, and their presence has been linked to declines in several sensitive species. However, the population size of coyotes has only been estimated from anecdotal reports and camera traps. Our goal was to estimate the size of the coyote population on Sanibel …

Cost-Effective Strategies For Feral Swine Control: Exploring Trapping Equipment Cooperatives, Phil Kenkel, Riza Radmehr, Rodney Holcomb, Mckenzie Boyce

Human–Wildlife Interactions

Feral swine (Sus scrofa) in the United States have become a growing concern, with a population of ≥6 million and causing annual damages of ≥$1.5 billion USD. Because of their high reproductive capacity, effective control methods are crucial to reducing or slowing their population growth. While remotely monitored and triggered traps have proven to be an effective control strategy, the cost of sophisticated trapping equipment, which can cost ≥$7,000 USD, is often cost prohibitive for many landowners. Despite the pressing need to address the challenge of making effective feral swine control methods more affordable, there are few studies …

Refine Fuels Treatments In The Wildland–Urban Interface With Wildlife In Mind, Miles Becker, Catrin M. Edgeley, David Stoner

Human–Wildlife Interactions

Conserving urban tree and shrub cover provides many benefits for wildlife and people, yet often becomes a lower priority than fuels treatments to mitigate fire risk in the wildland–urban interface (WUI). We support the principle that considering multiple objectives on privately owned property is valuable and can be achieved. Data sharing and collaboration between wildfire experts and wildlife biologists could improve the quality and extent of managing both animals and fire. Furthermore, the adoption of statewide policy and municipal regulations for preventing wildfires in the WUI provides an opportunity to incorporate ecological functions in the same directives for a balanced …

The Damage Done: How The Disease Model Of Addiction Harms Marginalized People In Canada, Sara Gordon

All Faculty Publications

Over 50,000 Canadians have died of unregulated drug poisoning since 2016. And while the toxic drug crisis is the leading cause of death in British Columbia for people between the ages of 10 and 59, some British Columbians are at a higher risk than others. In 2023, First Nations people—who comprise 3.4% of BC’s population—accounted for 17.8% of its toxic drug deaths. Other marginalized communities are also at heightened risk: racialized people, young people, and people living in poverty or without shelter are all disproportionately impacted. These disparities reflect more than a public health crisis—they largely exist due to legal …

Binding Rights: Contractual Federalism And The Right To Housing In Canada, Alexandra Flynn

All Faculty Publications

Canada’s housing crisis continues to deepen, exacerbated by constitutional fragmentation and intergovernmental reluctance to implement human rights-based housing policy. While the federal National Housing Strategy Act recognizes housing as a human right, its application is limited and its legal force is limited to the federal level, leaving provinces and municipalities unbound. This article argues that contract law – particularly conditional funding agreements between the federal government and subnational actors – can serve as a pragmatic and legally coherent mechanism to bind municipalities to housing obligations, including the recognition of housing as a human right. Drawing on the Canada Health Act …

Unseen Connections: A Storymap Exploring Case Studies In Water-Energy Transitions And Environmental Justice, Alida Cantor, Elizabeth Bartholomew, Kate Berry, James Blair, Dustin Mulvaney, Nancee Hunter

Geography Faculty Publications and Presentations

Climate change is one of the most important challenges in the world today. Communities and decision makers at many levels, from local to international, are working to ensure that energy, water, and other societal infrastructures can transition and adapt to address climate change (IPCC, 2023). One major mitigation strategy involves the decarbonization of energy systems (Rockström et al. 2017). Despite wide recognition of the need to decarbonize globally, renewable energy infrastructures and technologies are often locally controversial, involving claims of environmental injustice and disputes over land and water (Cantor, Turley, and Maxfield 2023; Jerez, Garcés, and Torres 2021; Turley et …

Law-Following Ai: Designing Ai Agents To Obey Human Laws, Cullen O'Keefe, Ketan Ramakrishnan, Janna Tay, Christoph Winter

Fordham Law Review

Artificial intelligence (AI) companies are working to develop a new type of actor: “AI agents,” which we define as AI systems that can perform computer-based tasks as competently as human experts. Expert-level AI agents will likely create enormous economic value but also pose significant risks. Humans use computers to commit crimes, torts, and other violations of the law. As AI agents progress, therefore, they will be increasingly capable of performing actions that would be illegal if performed by humans. Such lawless AI agents could pose a severe risk to human life, liberty, and the rule of law.

The Role Of Psychological Capital On Organisational Citizenship Behaviours Within The Ghanaian Public Sector: A Conservation Of Resources Perspective., Duke Debrah Afrane

Doctoral

The public sector of Ghana has been plagued with low productivity issues for over a decade. Psychological capital is a resource that can increase citizenship behaviours, which help to boost productivity. Conservation of resources theory provides a mechanism for explaining the role that psychological capital plays in encouraging organisational citizenship behaviours. This mechanism is reflected in the value of psychological capital among employees and context-specific factors within the omnibus and discrete contexts of the Ghanaian public sector. The thesis explored this through a two-phase research method. Firstly, employing semi-structured interviews to explore the value of psychological capital, and identify perception …

Differences In Cellular And Humoral Immune Responses To A Primary And Secondary Immunization With Herpesvirus Of Turkey (Hvt) Vaccine In Layer Pullets, Allie K. Bowerman, Chrysta N. Beck, Jossie M. Santamaria, Gisela F. Erf

2025 Research Poster Competition

In poultry production, chickens are routinely vaccinated with live herpesvirus vaccines for protection from lymphoma causing Marek’s disease virus. However, information on the immune responses to these vaccines is limited. This study examined cellular and antibody responses to primary and secondary vaccinations with herpesvirus of turkey (HVT). Six unvaccinated 9-wk-old, and six HVT-vaccinated (s.c. at hatch) 19-wk-old, layer pullets received a first (V1) or a second (V2) HVT vaccination, respectively, by intradermal injection of HVT-vaccine into the pulp of growing feathers (GFs; 10 µL/GF; 16 GFs/bird). GFs were collected before (0h), and at 0.25, 1, 2, 3, 5, 7, and …

Leukocyte Infiltration Profiles At The Site Of Intradermal Injection Of Silikon-1000 In Scleroderma-Prone Ucd200/206 And Healthy White Leghorn Chickens, Katee L. Johnson, Jossie M. Santamaria, Chrysta N. Beck, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Intradermal injections of silicone-based fillers for the face and body may cause chronic inflammation and fibrotic reactions in some individuals. Chickens from the UCD 200/206 White Leghorn (WL) line spontaneously develop a fibrotic autoimmune disease known as scleroderma/systemic sclerosis (SSc). Using the SSc-prone UCD and healthy WL chickens, a longitudinal study was conducted to examine the cellular inflammatory responses to intradermal (i.d.) injections of sterile SILIKON-1000. Specifically, the pulp (a skin derivative) of growing feathers (GFs) was i.d. injected with sterile SILIKON-1000 or phosphate-buffered saline (PBS) as injection control (8 and 3 birds/line, respectively; 10 µL/GF; 20 GFs/bird). Two GFs …
