Characterizing Relational Values to Inform Message-Framing at the Boa Ogoi Historical Site

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 process of building a cultural interpretive center at Boa Ogoi, as well as restoring the land surrounding the site of the 1863 Bear River Massacre to ecological conditions similar to the years before the event. The Tribe has shown interest in working with their neighbors, particularly those upstream. This could help them achieve larger restoration goals for Boa Ogoi, particularly improving the highly degraded water quality on the site. This research seeks to inform the Tribe’s and the Tribe’s restoration collaborators’ communication efforts with upstream landmanagers. My first study uses interview data with 12 nearby land managers to identify important values underlying the relationship that local land stewards have with the management of their land. I compare these values with a profile of the dominant political and religious groups of the area. Interview participants largely identify as land stewards who feel a responsibility to care for land as well as their communities. In my second study, data from my interviews highlighted important plant and animal species in the region, specifically beaver, mule deer, elk, and Russian olive. My analysis of the relationships that landowners have with these species shows that they manage them largely out of a sense of responsibility to their neighbors and community, as well as a responsibility to future generations. Many of the study participants were members of families who had resided in the area for multiple generations, which gives many of them knowledge of and preferences related to managing these species. Understanding how these individuals value the species in question could be important for building working relationships between the Tribe and their neighbors, such as collaborative invasive species management and a collective effort to improve habitat for valued game species like mule deer

Aerodynamic performance of conventional and advanced design labyrinth seals with solid-smooth abradable, and honeycomb lands

Labyrinth air seal static and dynamic performance was evaluated using solid, abradable, and honeycomb lands with standard and advanced seal designs. The effects on leakage of land surface roughness, abradable land porosity, rub grooves in abradable lands, and honeycomb land cell size and depth were studied using a standard labyrinth seal. The effects of rotation on the optimum seal knife pitch were also investigated. Selected geometric and aerodynamic parameters for an advanced seal design were evaluated to derive an optimized performance configuration. The rotational energy requirements were also measured to determine the inherent friction and pumping energy absorbed by the various seal knife and land configurations tested in order to properly assess the net seal system performance level. Results indicate that: (1) seal leakage can be significantly affected with honeycomb or abradable lands; (2) rotational energy absorption does not vary significantly with the use of a solid-smooth, an abradable, or a honeycomb land; and (3) optimization of an advanced lab seal design produced a configuration that had leakage 25% below a conventional stepped seal

An investigation into linearity with cumulative emissions of the climate and carbon cycle response in HadCM3LC

We investigate the extent to which global mean temperature, precipitation, and the carbon cycle are constrained by cumulative carbon emissions throughout four experiments with a fully coupled climate-carbon cycle model. The two paired experiments adopt contrasting, idealised approaches to climate change mitigation at different action points this century, with total emissions exceeding two trillion tonnes of carbon in the later pair. Their initially diverging cumulative emissions trajectories cross after several decades, before diverging again. We find that their global mean temperatures are, to first order, linear with cumulative emissions, though regional differences in temperature of up to 1.5K exist when cumulative emissions of each pair coincide. Interestingly, although the oceanic precipitation response scales with cumulative emissions, the global precipitation response does not, due to a decrease in precipitation over land above cumulative emissions of around one trillion tonnes of carbon (TtC). Most carbon fluxes and stores are less well constrained by cumulative emissions as they reach two trillion tonnes. The opposing mitigation approaches have different consequences for the Amazon rainforest, which affects the linearity with which the carbon cycle responds to cumulative emissions. Averaged over the two fixed-emissions experiments, the transient response to cumulative carbon emissions (TCRE) is 1.95 K TtC-1, at the upper end of the IPCC’s range of 0.8-2.5 K TtC-1

The City by the Pool

This volume offers a new and up-to-date synthesis of Lincoln's long history as a major city and regional capital, from prehistory to 1945. The 'City by the Pool' was a major religious centre long before the Roman invasion and from bronze-age shamans to early Baptists people have always been attracted here for spiritual as well as mundane purposes. The authors argue for the presence of a major ritual causeway of the late Bronze and Iron Age and outline the extent to which ritual monuments also contributed to the character of Roman Lincoln. This book is based on more than a hundred publicly-funded excavations and building surveys undertaken between 1945 and 2000. It surveys all aspects of city life, from housing and fortifications to the water supply and rubbish disposal. It includes a CD Rom with a Geographic Information System (GIS) and a relational data-base known as LARA (the Lincoln Archaeological Research Assessment)

Brief Note: Fallicambarus (Creaserinus) fodiens (Cottle 1863) (Decapoda: Cambaridae) in West Virginia: A New State Record

Author Institution: Department of Zoology, The Ohio State University, University DriveA population of F. (C.) fodiens was found in the floodplain of the Ohio River, Mason County, West Virginia. This is a new state record and the second record of the species on the unglaciated Appalachian Plateau. An analysis of burrow diameters indicated that three age classes are probably present

Some rare cases of chimerism in twin cattle and their proposed use in determining germinal cell migration

Three dizygotic, heterosexual twins with chimerisms carrying marker chromosomes are described. Phenotypic and cytogenetic methods were used to identify these animals. The occurrence of germinal cell migration causing gonad chimerism can be detected by the marker chromosome event under conditions described in this repor

Implementing virtual pheromones in BDI robots using MQTT and Jason

Robotic coordination is a crucial issue in the development of many applications in swarm robotics, ranging from mapping unknown and potentially dangerous areas to the synthesis of plans to achieve complex tasks such as moving goods between locations under resource constraints. In this context, stigmergy is a widely employed approach to robotic coordination based on the idea of interacting with the environment by means of markers called pheromones. Pheromones do not need to be "physical marks", and a number of works have investigated the use of digital, virtual pheromones. In this paper, we show how the concept of virtual pheromones can be implemented in Jason, a Java-based interpreter for an extended version of AgentSpeak, providing a high-level modelling and execution environment for multi-agent systems. We also exploit MQTT, a messaging infrastructure for the Internet-of-Things. This allows the implementation of stigmergic algorithms in a high-level declarative language, building on top of low-level infrastructures typically used only for controlling sensors and actuators
