What Lies Beneath: Treatment of Canvas-backed Pennsylvania Coal Mining Maps for Digitization

An ongoing program to preserve approximately seven hundred oversized, canvas-backed, coal mining maps from the CONSOL Energy Mining Map Collection was initiated by the University of Pittsburgh (Pitt) in 2007, supported by funding from the United States Department of the Interior Office of Surface Mining and Reclamation (OSM) and the Pennsylvania Department of Environmental Protection (PA-DEP). The main goal of this project is to stabilize and clean the mining maps for digitization at the OSM National Mine Map Repository (NMMR) located in Pittsburgh, Pennsylvania. The digitized data of the underground mines will be incorporated into Geographical Information Systems relative to mine safety, land reclamation, current mining operations, and new development

State of the Art of Soil Improvements with Case Histories

This paper presents an overview of selected soil improvement techniques, with significant case histories. The soil improvement techniques discussed include Vibro-Compaction, Vibro-Replacement (stone columns), Dynamic Deep Compaction, compaction grouting, chemical grouting, jet grouting and soil fracture grouting

Behind the Concrete Curtain: Acknowledging and Curbing Greenhouse Gas Emissions from Hydroelectric Facilities and River Impoundments

From its early use as kinetic power to kick start the industrial revolution, a consensus emerged that hydroelectric power is clean, renewable, and reliable. In contemporary parlance it is universally classified as either “carbon free” or “low-carbon.” The history of hydropower in the United States supports this belief, and its use has rarely been scrutinized. However, an emerging consensus indicates scrutiny is necessary (for hydroelectric power and other energy sources avoiding acute assessment) given the challenges foisted upon us by anthropogenic climate change. This Article will put the standard hydropower consensus to task and analyze whether it holds water as a resource that can be heavily relied upon in a clean energy transition. First, a review of the United States’ history with hydropower will summarize the construction of a ubiquitous pro-power narrative that pervaded hydroelectric conversations well into the 1970s. A narrative that has recently found favor again as the global community seeks a path to avoid the worst effects of climate change. Second, this Article will discuss the nascent scientific consensus around the impact of twentieth and twenty-first century proliferation of hydropower and river impoundments. Third, this Article will explore current federal legislative tools available to account for and mitigate future impacts, including suggestions to amend current legislation to require analysis of hydroelectric impact on climate change. Finally, this Article will analyze national policy regarding prospective development and reliance on hydropower

Using an identity lens : constructive working with children in the criminal justice system

Research has shown that identity, and how you feel about yourself, can be key to moving forward with life and away from crime. Working with the University of Salford, Youth Offending Teams and supported by the Barrow Cadbury Trust, this resource has been developed to promote a constructive, identity-focused approach to ultimately help divert children away from progressing further through the criminal justice system. Using the principles of the Nacro-led Beyond Youth Custody programme, this toolkit outlines how these can be applied to working with children before custody to support them towards positive outcomes and prevent further offending

Applying a Team Performance Framework to better Understand the Handoff Process: Part 2

In healthcare, handoffs are crucial when it comes to transitioning care of patients from one provider to another. Handoffs are communication events between providers that include the background and treatment plan, as well as all pertinent information involving the patient (Paterson, 2010). There are many factors that influence the reliability and transfer of the information being passed during a handoff. In order to understand the way these factors influence and change the handoff process, they were organized according to the input - mediator - output – input (IMOI) model. The IMOI model claims that the productivity and effectiveness of interactions between team members can be influenced by cognitive, affective, and external factors (Weaver, Feitosa, Salas, Seddon, & Vozenilek, 2013). The IMOI also clarifies that the output affects the performance of the team in the future through a feedback loop. This paper focuses specifically on the Output – Input stages, as well as future implications that come from understanding handoffs within the IMOI model

New Methods for Assessing the Sustainability of Wood-burning Energy Facilities

Methods to assess wood-based bioenergy projects have tended to focus on technological and physical constraints. Less is known about how longer-term environmental, economic, and social systems—the three pillars of sustainable development—have influenced technological development in the context of woody biomass energy. This research offers new methods for assessing the sustainability of wood-based energy projects by combining spatial analysis, semi-structured interviews, and archival data analysis. By integrating quantitative and qualitative methods, this project offers ways to understand how social and environmental dynamics from the past shape technological development in the future. A propensity analysis of biomass energy plants in Michigan, USA was performed using US Census data grouped by social, economic, and environmental categories. This quantitative analysis helped to characterize community and landscape types in which woody biomass plants were developed in Michigan in the late-twentieth century. To help illustrate some of the often-hidden social and political dimensions of energy development, such as access to decision-making and attitudes toward bioenergy projects, transcripts of public hearings, media coverage, and other archival sources were examined, and 30 stakeholder interviews were conducted. By integrating these qualitative and quantitative approaches, this paper aims to provide a more comprehensive approach to assessing the sustainability of wood-based biofuel technologies

Detection Of KOI-13.01 Using The Photometric Orbit

We use the KOI-13 transiting star-planet system as a test case for the recently developed BEER algorithm (Faigler & Mazeh 2011), aimed at identifying non-transiting low-mass companions by detecting the photometric variability induced by the companion along its orbit. Such photometric variability is generated by three mechanisms, including the beaming effect, tidal ellipsoidal distortion, and reflection/heating. We use data from three Kepler quarters, from the first year of the mission, while ignoring measurements within the transit and occultation, and show that the planet's ephemeris is clearly detected. We fit for the amplitude of each of the three effects and use the beaming effect amplitude to estimate the planet's minimum mass, which results in M_p sin i = 9.2 +/- 1.1 M_J (assuming the host star parameters derived by Szabo et al. 2011). Our results show that non-transiting star-planet systems similar to KOI-13.01 can be detected in Kepler data, including a measurement of the orbital ephemeris and the planet's minimum mass. Moreover, we derive a realistic estimate of the amplitudes uncertainties, and use it to show that data obtained during the entire lifetime of the Kepler mission, of 3.5 years, will allow detecting non-transiting close-in low-mass companions orbiting bright stars, down to the few Jupiter mass level. Data from the Kepler Extended Mission, if funded by NASA, will further improve the detection capabilities.Comment: Accepted to AJ on October 4, 2011. Kepler Q5 Long Cadence data will become publicly available on MAST by October 23. Comments welcome (V2: minor changes, to reflect proof corrections

Applying a Team Performance Framework to better Understand the Handoff Process: Part 1

Handoffs require critical information transfers that are clear, comprehensible, and correct from receiver to sender. There are many factors that influence the reliability of the information in a handoff procedure, and impact the subsequent choices that are made that affect patient care. Using the Input – Mediator – Output – Input model multiple factors that influence the information transfer process have been identified to better handoff communication and in turn, lead to better patient care. The IMOI model is a recently developed theory that claims the productivity and value of interaction among team members can be influenced by cognitive, affective, and external factors (Weaver et al., 2013). This clarifies that the output affects the future performance of a group through a feedback loop, as well as reflects variability in mediational influences. This paper focuses on the first two parts of the IMOI model; input and mediators. Individual characteristics affect the handoff process for both the sender and receiver, including attitudes, expertise, experience, expectations, and fitness for duty. The inputs of a handoff are the individual characteristics of the providers and the patient case, where mediation is the shared process to develop an outcome. The attitudes, expertise, experience, and fitness for duty influence the composition of the team, but are moderated by factors such as interventions, communication, resources, team monitoring, and team orientation. By understanding these factors, providers can create a safer environment and provide safer patient care

Psychology and the Church: An Exemplar of Psychologist-Clergy Collaboration

Despite the increasing attention being given to clergy-psychologist collaboration, many psychologists may wonder what clergy-psychologist collaboration looks like in actual practice. The authors describe an example of clergy-psychologist collaboration involving a careful needs-assessment phase followed by the development of a wide spectrum of preventive, consultative, and direct services. Current challenges include funding, establishment of trust, and the integration of psychology and spirituality. Implications for professional psychologists are discussed

The long-line graph of a combinatorial geometry. II. Geometries representable over two fields of different characteristics

AbstractLet q be a power of a prime and let s be zero or a prime not dividing q. Then the number of points in a combinatorial geometry (or simple matroid) of rank n which is representable over GF(q) and a field of characteristic s is at most (qν − qν−1)(2n+1)−n, where ν = 2q−1 − 1
