Distribution, Abundance And Natural Enemies Of The Invasive Tomato Leafminer, Tuta Absoluta (Meyrick) In Kenya, G. Kinyanjui, F. M. Khamis, F. L.O. Ombura, E. U. Kenya, S. Ekesi, S. A. Mohamed

All Peer-Reviewed Publications

Tuta absoluta (Meyrick) has become a serious menace to sustainable production of tomato in Kenya. A survey was conducted between April 2015 and June 2016 to determine its distribution, abundance, infestation, and damage levels on tomato, and associated natural enemies. Trap counts of T. absoluta moths were recorded in all surveyed 29 counties, which indicated its nationwide distribution irrespective of altitude. Tuta absoluta was present in both open fields and greenhouses. The highest moth/trap/day was 115.38 ± 15.90. Highest leaf infestation was 92.22% and the highest number of mines and larvae per leaf were 3.71 ± 0.28 and 2.16 ± …

Paleoindian Response To Climate Change In The Northern Jornada Del Muerto, Christopher Wayne Merriman

Anthropology ETDs

Human-environment interaction is a long-standing and productive line of inquiry that includes the study of cultural responses to climate change. However, demonstrating a causal relationship between climate change and the consequent culture change is rarely straightforward for numerous reasons. In this dissertation I develop an optimality model to predict how Paleoindians should have responded to changes in precipitation across the Late Pleistocene-Early Holocene. The water supply model (WSM) ranks water supplies much like the diet breadth model ranks food resources. To adjust the WSM for climate change, paleoclimate records from playas in the northern Jornada del Muerto were used in …

Impacts Of Deepwater Horizon On Fish And Fisheries: What Have We Learned About Resilience And Vulnerability In A Coupled Human-Natural System?, S.A. Murawski, C.B. Paris, Tracey Sutton, M. Cockrell, S. O'Farrell, J. Sanchirico, E. Chancellor, L. Perruso

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The Deepwater Horizon (DWH) oil spill occurred in a region of the Gulf of Mexico (GoM) supporting abundant, diverse and valuable communities of fishes and fishers. The economy of the northern GoM is inextricably tied to the natural resource bases of the region (tourism, fishing, oil and gas, etc.) and thus the coupling between the human and ecological systems is tight and subject both feed-back and, to some extent, feed-forward controls. Management actions taken during the 87-day DWH spill incident included the closure of over 280,000 km² of productive fishing area (about 1/3 of USA federal waters in the …

Developing A Practice In Remote Sensing For Next-Generation Human Rights Researchers, Theresa Harris, Jonathan Drake, Umesh K. Haritashya, Wumi Asubiaro Dada, Fredy Cumes

Biennial Conference: The Social Practice of Human Rights

Remote sensing is increasingly recognized as an important tool for documenting human rights abuses. When used alongside interviews, case studies, surveys, forensic science, and other well-established research methods in human rights and humanitarian practice, remotely sensed data can effectively geolocate and establish chronologies for mass graves, forced displacement, destruction of cultural heritage sites, and other violations. But as a highly technical field of science that relies on ever-changing technologies, remote sensing and geospatial analysis are not readily accessible for human rights and humanitarian practitioners. The community of practice grew out of innovative work by practitioners at NGOs and specialized inter-governmental …

Investigating Depth Estimation To Archaeological Magnetic Source Bodies, Jeremy G. Menzer

Graduate Theses and Dissertations

Magnetometry is the most widely applied archaeo-geophysical technique. Current practice standards employ the technique to map only in a two-dimensional plan view fashion, but in deep geologic studies depth estimators are routinely applied to magnetic datasets. These estimators provide three-dimensional information to magnetic source-bodies. There are many different depth estimators employed in geologic study that all require various degrees of processing complexity. This study investigates two mathematically simple techniques, half-width rules and multi-height methods. Half-width rules are likely the oldest depth estimators within the field while multi-height techniques are but a minor footnote in the literature. The applicability of these …

Comparative Analysis Of Kmer Counting And Estimation Tools, Ankitha Vejandla

School of Computing: Dissertations, Theses, and Student Research

The rapid development of next-generation sequencing (NGS) technologies for determining the sequence of DNA has revolutionized genome research in recent years. De novo assemblers are the most commonly used tools to perform genome assembly. Most of the assemblers use de Bruijn graphs that break the sequenced reads into smaller sequences (sub-strings), called kmers, where k denotes the length of the sub-strings. The kmer counting and analysis of kmer frequency distribution are important in genome assembly. The main goal of this research is to provide a detailed analysis of the performance of different kmer counting and estimation tools that are currently …

Examining Psilocybin And Lsd Consumption Through A Geographical Lens, Nicole Sarah Caruana

Characterizing Relational Values To Inform Message-Framing At The Boa Ogoi Historical Site, Cole G. Stocker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In an increasingly polarized political climate–particularly in the U.S.– environmental issues such as climate change and its effects on the environment have become hot-button partisan talking points resulting in further division. This has led to research on ways to communicate science which does not further inflame political tensions, but rather reinforces and validates the audience’s values. Science communication research provides the foundation for my case study, which focuses on characterizing the environmental values and worldviews of land managers residing and working near the Boa Ogoi Historical Site in southern Idaho. The Northwest Band of Shoshone Nation (NWBSN) is in the …

Russian Logics And The Culture Of Impossible: Part 1. Recovering Intelligentsia Logics, Ksenia Tatarchenko, Anya Yermakova, Liesbeth De Mol

Research Collection College of Integrative Studies

This article reinterprets algorithmic rationality by looking at the interaction between mathematical logic, mechanized reasoning, and, later, computing in the Russian Imperial and Soviet contexts to offer a history of the algorithm as a mathematical object bridging the inner and outer worlds, a humanistic vision that we, following logician Vladimir Uspensky, call the “culture of the impossible.” We unfold the deep roots of this vision as embodied in scientific intelligentsia. In Part I, we examine continuities between the turn-of-the-twentieth-century discussions of poznaniye—an epistemic orientation towards the process of knowledge acquisition—and the postwar rise of the Soviet school of mathematical logic. …

Modeling User Relationships In Online Communities Of Creators, Berkeley Andrus

Theses and Dissertations

Those who study creativity, especially from a computational perspective, have long understood the role of social influence in the creative process. This has motivated many efforts to simulate social mechanics in artificial creative systems. However, these simulations have often replicated generic or assumed human behaviors rather than specific anthropological data. In this work we take a more focused approach by quantitatively measuring interactions between creators in online social communities and replicating observed phenomena in a simulated environment. The primary contributions of this thesis are 1) defining quantitative metrics for comparing human and simulated social networks of creators, 2) providing social …

Facilitating Heuristic Evaluation For Novice Evaluators, Anas Abulfaraj

College of Computing and Digital Media Dissertations

Heuristic evaluation (HE) is one of the most widely used usability evaluation methods. The reason for its popularity is that it is a discount method, meaning that it does not require substantial time or resources, and it is simple, as evaluators can evaluate a system guided by a set of usability heuristics. Despite its simplicity, a major problem with HE is that there is a significant gap in the quality of results produced by expert and novice evaluators. This gap has made some scholars question the usefulness of the method as they claim that the evaluation results are a product …

Human-Centric Cybersecurity Research: From Trapping The Bad Guys To Helping The Good Ones, Armin Ziaie Tabari

USF Tampa Graduate Theses and Dissertations

The issue of cybersecurity has become much more prevalent over the last few years, with a number of widely publicised incidents, hacking attempts, and data breaches reaching the news. There is no sign of an abatement in the number of cyber incidents, and it would be wise to reconsider the way cybersecurity is viewed and whether a mindset shift is necessary. Cybersecurity, in general, can be seen as primarily a human problem, and it is for this reason that it requires human solutions and tradeoffs. In order to study this problem, using two perspectives; that of the adversaries and that …

Late Pleistocene And Early Holocene Sea-Level History And Glacial Retreat Interpreted From Shell-Bearing Marine Deposits Of Southeastern Alaska, Usa, James F. Baichtal, Alia J. Lesnek, Risa J. Carlson, Nicholas S. Schmuck, Jane L. Smith, Dennis J. Landwehr, Jason P. Briner

Publications and Research

We leverage a data set of >720 shell-bearing marine deposits throughout southeastern Alaska (USA) to develop updated relative sea-level curves that span the past ~14,000 yr. This data set includes site location, elevation, description when avail-able, and 436 14C ages, 45 of which are published here for the first time. Our sea-level curves suggest a peripheral forebulge developed west of the retreating Cordilleran Ice Sheet (CIS) margin between ca. 17,000 and 10,800 calibrated yr B.P. By 14,870 ± 630 to 12,820 ± 340 cal. yr B.P., CIS mar-gins had retreated from all of southeastern Alaska’s fjords, channels, and passages. At …

Communicating And Co-Producing Information With Stakeholders: Examples Of Participatory Mapping Approaches Related To Sea Level Rise Risks And Impacts, Pragati Rawat, Khairul A. Anua, Juita-Elena (Wie) Yusuf, Jon Derek Loftis, Ren-Neasha Blake

School of Public Service Faculty Publications

This chapter discusses practical approaches for using participatory mapping as a tool to visualize and communicate sea level rise (SLR) and climate change risks, to share information about the vulnerability to, and threats of, climate change, and to co-produce knowledge with stakeholders. The examples presented in this chapter are from demonstrated applications in communities in Virginia (USA) that involve participatory mapping and that utilize a web-Geographic Information System (GIS). The web-GIS is innovatively combined with other technologies and participatory processes to create low-cost high-tech approaches so that even people with little to no knowledge of GIS can interact with maps …

Battling Over Bathwater: Greywater Technopolitics In Los Angeles, Sayd Randle

Research Collection College of Integrative Studies

In Los Angeles, domestic wastewater recycling ("greywater") systems are controversial, loved by local environmentalists and disdained by the city's water agencies. Drawing on fieldwork among greywater advocates and public water agency workers, this article examines how greywater systems function as nodes that unsettle relations between residents and the public agencies that manage the city's water grid. Elaborating the longstanding frictions over greywater reuse in LA reveals how these fixtures are mobilized by advocates to rescript the roles of both individuals and the state within the urban waterscape. Detailing public agency workers' resistance to this form of selective disconnection from the …

Shape-Based Classification Of Partially Observed Curves, With Applications To Anthropology, Gregory J. Matthews, Karthik Bharath, Sebastian Kurtek, Juliet K. Brophy, George K. Thiruvathukal, Ofer Harel

Computer Science: Faculty Publications and Other Works

We consider the problem of classifying curves when they are observed only partially on their parameter domains. We propose computational methods for (i) completion of partially observed curves; (ii) assessment of completion variability through a nonparametric multiple imputation procedure; (iii) development of nearest neighbor classifiers compatible with the completion techniques. Our contributions are founded on exploiting the geometric notion of shape of a curve, defined as those aspects of a curve that remain unchanged under translations, rotations and reparameterizations. Explicit incorporation of shape information into the computational methods plays the dual role of limiting the set of all possible completions …

Long-Term Socio-Ecological Research In The Biosphere Reserve In Mapimi, Mexico: A Multidimensional Participatory Observatory Of Rangeland/Pastoral Systems, V. M. Reyes Gómez, Elisabeth Huber-Sannwald, N. Martínez Tagüeña, I. Espejel Carvajal, S. Lucatello, M. A. Bowker, C. L. Lauterio Martínez

IGC Proceedings (1977-2023)

Since the creation of the UNESCO Biosphere Reserve Mapimi (BRM) in Mexico 45 years ago, pastoralism has undergone a series of transformations. Upon the arrival of the Spaniards, horse breeding flourished until 1900; thereafter extensive cattle production lasted for six decades. Only recently, farmers have adopted alternative management types for organic meat production. National and international efforts to achieve the Sustainable Development Goals (SDGs) require basic, applied, and participatory research efforts. In the socio-ecological pastoral system BRM, first halophytic ecosystems were examined for their ecohydrological role in rangeland productivity. In 1996, a long-term ecological research site was installed to monitor …

Wildlife Conservation And The Role Of The Indigenous Communities Living Around Conservation Areas, N. Parmisa, K. A. Galvin

IGC Proceedings (1977-2023)

The Indigenous Kenyan Maasai community has coexisted with the wildlife surrounding it for decades from Nairobi National Park, Maasai Mara and Amboseli. These parks border Maasai lands. Although the northern, eastern, and western perimeters of the Nairobi National Park are fenced, the southern part is not. It is at this point that the Maasai community’s land meets the park. This area also acts as a wildlife dispersal area where wildlife can freely migrate to other parks, including Maasai Mara and Amboseli. The park is only 117sq kms and its vitality depends on the plains to the south where the Maasai …

Producing Useful Knowledge For Sustainable Development, K. A. Galvin

IGC Proceedings (1977-2023)

Africa makes a relatively minor contribution to global greenhouse gas emissions compared with developed nations, yet the African continent will be increasingly vulnerable to climate change processes in the coming decades. Critical challenges include meeting basic needs for food, water, shelter, and other necessities without undermining biodiversity and ecosystem services. Coordination efforts to address multiple global change related stressors has generally occurred at the national level and taken an external approach, with national governments favoring collaboration with foreign-based NGOs and other international institutions. However, the involvement of actors at the local level correlates with decisions that are better adapted to …

Climate Change Policy Narratives And Pastoralist Predicaments In The Horn Of Africa: Insights From Ethiopia And Kenya, T. Campbell

IGC Proceedings (1977-2023)

Drawing on the findings of a two-country case study, this paper examines the discourses and narratives found in contemporary climate change and national development policy in Ethiopia and Kenya, the actors shaping those policy narratives, and in turn, their consequences for pastoralism. The research reveals that while concerns around climate change and calls for strengthening resilience of dryland communities have given a new impetus to pastoral development, old arguments and assumptions that depict pastoral areas, and pastoralists, as unproductive and in need of modernisation remain deeply embedded in policy making. These open up spaces for the state, investors, and local …

Valuing The Expertise Of Mobile Herders In Arid South Africa--A Photographic Essay, C. F. Cupido, W. Ellis, M. I. Samuels

IGC Proceedings (1977-2023)

Pastoralism has been practiced for millennia in numerous ecosystems across the world. Throughout history, pastoral systems and in particular herding have been replaced by the commercialization of livestock production, which essentially made herders redundant in many sub-Sahara countries resulting in job losses. Herding is however still practiced in many countries, but the essential role of the herder is in many instances snubbed upon and disregarded as trivial work, hence their low social standing within the community. Literature however indicates that herding does offer many benefits over commercial paddock systems e.g. improving rural livelihoods, reviving customary practice, reducing stock theft, reducing …

Towards A Holistic Understanding Of Pastoralism, M. Cabeza, P. Manzano, D. Burgas, L. Cadahía, J. Eronen, Á. Fernández-Llamazares, S. Bencherif, Ø. Holand, M. Fortelius, O. Seitsonen, María E. Fernández-Giménez, K. A. Galvin, N. Chr. Stenseth

IGC Proceedings (1977-2023)

Pastoralism is a globally-important livelihood, with large social, environmental and economic importance across much of our planet. Yet, it is also a vulnerable practice with widespread crises, urgently calling for better systemic understanding. The current disciplinary compartmentalization of research not only hampers this but allows perpetuation of unfortunate misconceptions. Furthermore, a long-standing marginalization of the livelihood prevails, with pastoralism being largely overlooked in international environmental and economic forums or sustainability agendas.

Here we call for transformative approaches to pastoralism research that can advance an integrated understanding of these social-ecological systems through a comparative lens. We develop a framework that uses: …

Interplays Between Policy And Practice On Rangelands In Kazakhstan Since The 1990s, C. Kerven

IGC Proceedings (1977-2023)

Kazakhstan contains a large share of the world’s remaining “near-natural” temperate grassland, so how the Kazakh rangelands are managed has global implications for plant and animal biodiversity, carbon stocks, and at a national level for the wellbeing of Kazakhstan’s land, people and the economy.

The extensive livestock and rangeland management systems of Kazakhstan were transformed after the early 1990s. Privatisation had deep and very damaging structural impacts. There are now considerable inequities in the distribution of state support, landed resources and livestock, with the appearance of a minority of large-scale livestock owners. Government policies allowed these livestock owners to register …
