An Examination Of Limiting Factors Of Chrysemys Picta Bellii (Western Painted Turtles) In The Lower Willamette River Basin, Oregon, James P. Holley

Environmental Science and Management Professional Master's Project Reports

Oregon’s two native freshwater turtle species, Chrysemys picta bellii (Western painted turtle) and Actinemys marmorata (Northwestern pond turtle), have seen significantly reduced population sizes since the founding of Portland in 1845, with estimates of up to 90% for A. marmorata. This project examined turtle nesting activity at 25 sites across a range of turtle populations and habitats around the Lower Willamette River Basin. All discovered turtle nesting activity was found in areas of high solar exposure. We found 93% of over 400 nest attempts to have been depredated across the 25 sites, well above most other reported rates. At …

Being In Centro: The Anthropology Of Schelling's Human Freedom, Michael Vater Jan 2021

Being In Centro: The Anthropology Of Schelling's Human Freedom, Michael Vater

Philosophy Faculty Research and Publications

Schelling presents the 1809 freedom essay as the idealistic flowering of a vision of system he always held. He is not disingenuous but somewhat perplexing in claiming that the system always was complete in nuce, even though not expounded completely. Tilliette captured the ambiguity nicely in designating Schelling’s oeuvre «une philosophie en devenir». This mid-career essay must be read backwards to the earliest essays republished with it—especially to their views of willing, freedom, and moral responsibility—and simultaneously forward to the late philosophy’s analysis of God’s freedom as freedom from being, even necessary being. I locate Freedom’s …

The Carbon Price Equivalent: A Metric For Comparing Climate Change Mitigation Efforts Across Jurisdictions, Gabriel Weil Jan 2021

The Carbon Price Equivalent: A Metric For Comparing Climate Change Mitigation Efforts Across Jurisdictions, Gabriel Weil

Scholarly Works

Climate change presents a global commons problem: Emissions reductions on the scale needed to meet global targets do not pass a domestic cost-benefit test in most countries. To give national governments ample incentive to pursue deep decarbonization, mutual interstate coercion will be necessary. Many proposed tools of coercive climate diplomacy would require a one-dimensional metric for comparing the stringency of climate change mitigation policy packages across jurisdictions. This article proposes and defends such a metric: the carbon price equivalent. There is substantial variation in the set of climate change mitigation policy instruments implemented by different countries. Nonetheless, the consequences of …

Determinants Of Non-Revenue Water, Haslinda Ab Malek, Mohamad Hafizi Zakaria, Muhammad Luqman Zulkifli, Nur Farahin Roslan

Malaysian Journal of Computing (MJoC)

Water is one of the most essential needs in human daily life. Water losses or Non-Revenue Water (NRW) refers to the treated water that has been produced from water plant which did not reach to the customer. This waste of water has caused the company to suffer losses and hence, burdens the people with increasing water tariff. Moreover, it becomes one of the challenges for commercial water system management because the water company must fulfil the demand from the society which keep increasing day by day. In addition, the demand for water is increasing, as the population is growing. Despite …

Big Data: Potential As An Ocular Epidemiology And Public Health Tool, Michael Moore Jan 2021

Big Data: Potential As An Ocular Epidemiology And Public Health Tool, Michael Moore

Doctoral

Refractive error is a significant cause of vision impairment both through the limited access to correction in some areas and the associated ocular diseases for which refractive errors are risk factors. Having timely, regular access to population level estimates of refractive error and vision impairment is necessary to adequately plan public health resources and resource appropriate interventions. A lack of access to current and regularly updated refractive error and vision impairment prevalence data has been identified as a significant limitation in predicting future population trends with many countries lacking any prevalence data or available data being outdated. This project addresses …

Just-In-Time Pastureland Trait Estimation For Silage Optimization, Under Limited Data Constraints, Patricia O'Byrne Jan 2021

Just-In-Time Pastureland Trait Estimation For Silage Optimization, Under Limited Data Constraints, Patricia O'Byrne

Doctoral

To ensure that pasture-based farming meets production and environmental targets for a growing population under increasing resource constraints, producers need to know pastureland traits. Current proximal pastureland trait prediction methods largely rely on vegetation indices to determine biomass and moisture content. The development of new techniques relies on the challenging task of collecting labelled pastureland data, leading to small datasets. Classical computer vision has already been applied to weed identification and recognition of fruit blemishes using morphological features, but machine learning algorithms can parameterise models without the provision of explicit features, and deep learning can extract even more abstract knowledge …

Differential Etiology: Inferring Specific Causation In The Law From Group Data In Science, Joseph Sanders, David L. Faigman, Peter B. Imrey, Philip Dawid Jan 2021

Differential Etiology: Inferring Specific Causation In The Law From Group Data In Science, Joseph Sanders, David L. Faigman, Peter B. Imrey, Philip Dawid

Faculty Scholarship

In every toxic-tort case, the plaintiff must prove that the defendant exposed the plaintiff to something that caused an injury. The causal proof is in two parts: proof of general causation and proof of specific causation. General causation addresses the question of whether the exposure can cause injury in anyone. In the area of toxic torts, the evidence available to answer this question comes in the form of groupbasedstudies in the fields of toxicology, epidemiology, and genetics—studies that search for the effects of causes. Proof of general causation, however, is not enough. Because court cases focus on the individual, the …

Comparison Of Low-Cost Commercial Unpiloted Digital Aerial Photogrammetry To Airborne Laser Scanning Across Multiple Forest Types In California, James Edward Lamping Jan 2021

Comparison Of Low-Cost Commercial Unpiloted Digital Aerial Photogrammetry To Airborne Laser Scanning Across Multiple Forest Types In California, James Edward Lamping

Cal Poly Humboldt theses and projects

Science-based forest management requires quantitative information about forest attributes traditionally collected via sampled field plots in a forest inventory program. Remote sensing tools, such as active three-dimensional (3D) Light Detection and Ranging (lidar), are increasingly utilized to supplement and even replace field-based forest inventories. However, lidar remains cost prohibitive for smaller areas and repeat measurement, often limiting its use to single acquisitions of large contiguous areas. Recent advancements in unpiloted aerial systems (UAS), digital aerial photogrammetry (DAP) and high precision global positioning systems (HPGPS) have the potential to provide low-cost time and place flexible 3D data to support forest inventory …

Response Of Invertebrate Drift To Dam-Release Restoration Pulse Flows From Lewiston Dam On The Trinity River, Ca, Jasmine S. Williamshen Jan 2021

Response Of Invertebrate Drift To Dam-Release Restoration Pulse Flows From Lewiston Dam On The Trinity River, Ca, Jasmine S. Williamshen

Cal Poly Humboldt theses and projects

The widespread construction of dams to regulate rivers has dramatically altered aquatic ecosystems, but these impoundments also provide a unique opportunity to support freshwater conservation goals by implementing functional flow regimes designed to mitigate dam-related impacts on fisheries. Drifting invertebrates are an important food source for stream-dwelling juvenile salmonids such that drift feeding can be an energetically profitable foraging strategy, yet the effect of streamflow alterations on invertebrate drift dynamics is largely undetermined. Drift net samples were collected on four days before and four days during the ascending limb (14-42 m3/s) of restoration pulse flows in April 2020 …
