Recreational anglers' valuation of near-shore marine fisheries in Florida

This report describes and summarizes the results from a state-wide survey of Florida resident saltwater anglers. The survey was designed to provide estimates of the economic value anglers place on marginal changes in management of selected near-shore marine species. The Contingent valuation method was used to elicit angler willingness to pay for changes in management for redfish, seatrout , mullet, sheepshead, pompano. and king mackerel. Contingent valuation is a process in which respondents are presented with a detailed scenario that describes an opportunity to express their willingness to pay for a proposed change in current conditions. The process consists of three parts. First. the change in current conditions, or the "good" to be valued is described. Second, the payment method is described. The payment method is usually closely related to typical methods of buying goods similar to the one to be valued. Finally. the respondent is asked how much they would pay for the good described in the scenario. A special saltwater fishing license stamp that would allow the holder to take advantage of the described management change was used as a payment mechanism. (PDF contains 147 pages.

Putting You First: First-Generation Student Perceptions, Needs, and Engagement at Virginia Commonwealth University

You First at Virginia Commonwealth University (VCU) submitted a Request for Assistance with the need for increased engagement with VCU first-generation (FG) students. To address this request, a doctoral Capstone team conducted problem and context analysis, a literature review, a mixed-methods study analyzing institutional data, a survey of current FG students at VCU, and focus group sessions with FG students at VCU. The goal was to identify FG student perceptions of their FG identities, determine the needs of FG students, and uncover factors that impact FG students’ engagement with You First. Findings suggested that the underlying cause of minimal engagement with FG students is the lack of awareness of You First services and programs. The Capstone team identified key challenges for FG students and ways for You First to continue to improve its support of FG students. Recommendations focused on increasing awareness of You First, promoting FG student connections, providing more accessible information, formalizing partnerships across the institution, and cultivating inclusivity among FG students’ families

Promises of Law: The Unlawful Dispossession of Japanese Canadians

This article is about the origins, betrayal, and litigation of a promise of law. In 1942, while it ordered the internment of over twenty-one thousand Canadians of Japanese descent, the Canadian government enacted orders in council authorizing the Custodian of Enemy Property to seize all real and personal property owned by Japanese Canadians living within coastal British Columbia. Demands from the Japanese-Canadian community and concern from within the corridors of government resulted in amendments to those orders stipulating that the Custodian held that property as a “protective” trust and would return it to Japanese Canadians at the conclusion of the war. That is not what happened. In January 1943, a new order in council authorized the sale of all property seized from Japanese Canadians. The trust abandoned, a promise broken, the Custodian sold everything. This article traces the promise to protect property from its origins in the federal bureaucracy and demands on the streets to its demise in Nakashima v Canada, the Exchequer Court decision that held that the legal promise carried no legal consequence. We argue that the failure of the promise should not obscure its history as a product of multi-vocal processes, community activism, conflicting wartime pressures, and competing conceptions of citizenship, legality, and justice. Drawing from a rich array of archival sources, our article places the legacy of the property loss of Japanese Canadians at the disjuncture between law as a blunt instrument capable of gross injustice and its role as a social institution of good faith

CellLab-CTS 2015: continuous-time stochastic cellular automaton modeling using Landlab

CellLab-CTS 2015 is a Python-language software library for creating two-dimensional, continuous-time stochastic (CTS) cellular automaton models. The model domain consists of a set of grid nodes, with each node assigned an integer state code that represents its condition or composition. Adjacent pairs of nodes may undergo transitions to different states, according to a user-defined average transition rate. A model is created by writing a Python code that defines the possible states, the transitions, and the rates of those transitions. The code instantiates, initializes, and runs one of four object classes that represent different types of CTS models. CellLab-CTS provides the option of using either square or hexagonal grid cells. The software provides the ability to treat particular grid-node states as moving particles, and to track their position over time. Grid nodes may also be assigned user-defined properties, which the user can update after each transition through the use of a callback function. As a component of the Landlab modeling framework, CellLab-CTS models take advantage of a suite of Landlab's tools and capabilities, such as support for standardized input and output

Characterization of Transient Noise in Advanced LIGO Relevant to Gravitational Wave Signal GW150914

On 14 September 2015, a gravitational wave signal from a coalescing black hole binary system was observed by the Advanced LIGO detectors. This paper describes the transient noise backgrounds used to determine the significance of the event (designated GW150914) and presents the results of investigations into potential correlated or uncorrelated sources of transient noise in the detectors around the time of the event. The detectors were operating nominally at the time of GW150914. We have ruled out environmental influences and non-Gaussian instrument noise at either LIGO detector as the cause of the observed gravitational wave signal

Periods of High Intensity Solar Proton Flux

Analysis is presented for times during a space mission that specified solar proton flux levels are exceeded. This includes both total time and continuous time periods during missions. Results for the solar maximum and solar minimum phases of the solar cycle are presented and compared for a broad range of proton energies and shielding levels. This type of approach is more amenable to reliability analysis for spacecraft systems and instrumentation than standard statistical models

The Landlab v1.0 OverlandFlow component: a Python tool for computing shallow-water flow across watersheds

Representation of flowing water in landscape evolution models (LEMs) is often simplified compared to hydrodynamic models, as LEMs make assumptions reducing physical complexity in favor of computational efficiency. The Landlab modeling framework can be used to bridge the divide between complex runoff models and more traditional LEMs, creating a new type of framework not commonly used in the geomorphology or hydrology communities. Landlab is a Python-language library that includes tools and process components that can be used to create models of Earth-surface dynamics over a range of temporal and spatial scales. The Landlab OverlandFlow component is based on a simplified inertial approximation of the shallow water equations, following the solution of de Almeida et al. (2012). This explicit two-dimensional hydrodynamic algorithm simulates a flood wave across a model domain, where water discharge and flow depth are calculated at all locations within a structured (raster) grid. Here we illustrate how the OverlandFlow component contained within Landlab can be applied as a simplified event-based runoff model and how to couple the runoff model with an incision model operating on decadal timescales. Examples of flow routing on both real and synthetic landscapes are shown. Hydrographs from a single storm at multiple locations in the Spring Creek watershed, Colorado, USA, are illustrated, along with a map of shear stress applied on the land surface by flowing water. The OverlandFlow component can also be coupled with the Landlab DetachmentLtdErosion component to illustrate how the nonsteady flow routing regime impacts incision across a watershed. The hydrograph and incision results are compared to simulations driven by steady-state runoff. Results from the coupled runoff and incision model indicate that runoff dynamics can impact landscape relief and channel concavity, suggesting that on landscape evolution timescales, the OverlandFlow model may lead to differences in simulated topography in comparison with traditional methods. The exploratory test cases described within demonstrate how the OverlandFlow component can be used in both hydrologic and geomorphic applications

Infinite dimensional non-positively curved symmetric spaces of finite rank

This paper concerns a study of three families of non-compact type symmetric spaces of infinite dimension. Although they have infinite dimension they have finite rank. More precisely, we show they have finite telescopic dimension. We also show the existence of Furstenberg maps for some group actions on these spaces. Such maps appear as a first step toward superrigidity results.Comment: Some references have been adde
