Public And Private Worlds? Social History, Gender And Space, Fiona Williamson

Research Collection School of Social Sciences

Michael McKeon’s The Secret History of Domesticity is an important contribution to cultural and literary history, exploring how concepts of public and private evolved. His quest to uncover the ‘division of knowledge’ takes the reader on a journey through the low and high culture of literary genre, the history of print, art, architecture, entertainment, politics and social theory. This essay compares McKeon’s reading of public and private in light of the recent ‘spatial turn’ in social and gender history. The ‘spatial turn’ offers a close lens into the lived experience of past peoples in the same way that McKeon claims …

Constraining The Temperature History Of The Past Millennium Using Early Instrumental Observations, P Brohan, Rob Allan, J. Eric Freeman, D. Wheeler, Clive Wilkinson, Fiona Williamson

Research Collection School of Social Sciences

The current assessment that twentieth-century global temperature change is unusual in the context of the last thousand years relies on estimates of temperature changes from natural proxies (tree-rings, ice-cores, etc.) and climate model simulations. Confidence in such estimates is limited by difficulties in calibrating the proxies and systematic differences between proxy reconstructions and model simulations. As the difference between the estimates extends into the relatively recent period of the early nineteenth century it is possible to compare them with a reliable instrumental estimate of the temperature change over that period, provided that enough early thermometer observations, covering a wide enough …

Marijuana Use Development Over The Course Of Adolescence Among North American Indigenous Youth, Jacob E. Cheadle, Kelley J. Sittner Hartshorn

Department of Sociology: Faculty Publications

This study investigated the links between marijuana use trajectories and marijuana abuse/ dependence (DSM-IV) using five waves of data from 718 North American Indigenous adolescents between 10 and 17 years from eight reservations sharing a common language and culture. Growth mixture models indicated that 15% of youth began using by 11–12 years of age and that another 20% began shortly thereafter. These early users had odds of abuse/dependence 6.5 times larger than abstainers. Girls were also unexpectedly found to be particularly at risk of early use, and this did not reflect other background and psychosocial factors, including friend use. While …

All Peer-Reviewed Publications

The utilization of native trichogrammatids for biocontrol of Helicoverpa armigera (Hbn.) and their potential integration with pesticide use are currently receiving attention. In this study the interaction of adults of Trichogramma sp. nr. mwanzai and Trichogrammatoidea sp. nr. lutea with commonly used pesticide products was investigated. The toxicity of eight pest control products commonly used in vegetable crops in Kenya, were evaluated by exposing the adults of the two species to detached potted tomato leaves at different intervals after spraying. Two biologically derived products, Achook ® (neem-based) and Dipel ® (Bt ssp. kurstaki)-were found to be harmless and had no …

The Engagement Of Highly Skilled Egyptian Migrants In Oecd Countries, Iman Dawood

Faculty Journal Articles

Within the Middle East and North Africa region, Egypt can certainly be considered the number one emigration country in terms of total number of emigrants1 . But even within a larger pool of countries, the developing countries for instance, Egypt still occupies a position within the list of top ten-emigration countries according to the World Bank2 . Egypt is also amongst the top remittance-receiving countries with only thirteen other countries worldwide receiving a higher level of remittances in the year 20103 . While accounts of the actual number of Egyptian migrants vary greatly due to the unavailability of accurate and …

Noise Impacts From Professional Dog Grooming Forced-Air Dryers, Peter M. Scheifele, Michael T. Johnson, David C. Byrne, John G. Clark, Ashley Vandlik, Laura W. Kretschmer, Kristine E. Sonstrom

Electrical and Computer Engineering Faculty Research and Publications

This study was designed to measure the sound output of four commonly used brands of forced-air dryers used by dog groomers in the United States. Many dog groomers have questions about the effect of this exposure on their hearing, as well as on the hearing of the dogs that are being groomed. Readings taken from each dryer at 1 meter (the likely distance of the dryer from the groomer and the dog) showed average levels ranging from 105.5 to 108.3 dB SPL or 94.8 to 108.0 dBA. Using the 90 dBA criterion required by the US Occupational Safety and Health …

The Unprecedented Assimilation Of Mobile Telephony In Ireland: A Phenomenon Of The Celtic Tiger Era Or A Result Of Cultural Traits?, Andreas Scheibelhut

Masters

Following the universal acceptance of mobile telephony the once elitist gadget has become an indispensable democratic tool of everyday communications over the last three decades. Controversially, this thesis illustrates that its level of both adoption and usage did not develop in a similar homogenous pattern in selected OECD countries. In particular, the Irish performance is rather astonishing given the speed of adoption as well as the exceptional high revenue figures achieved by the wireless operators. Consequently, this work determines a selection of factors that drive and encourage both the adoption and usage of cellular telephony in Ireland. The Irish experience …

Strategic Activity In The Today’S Multinational Subsidiaries, Donal O'Brien, Pamela Sharkey Scott, Patrick Gibbons

Conference Papers

This working paper presents an ongoing empirical study into strategy development at the subsidiary management level of the Multinational Enterprise (MNE). The multinational subsidiary is a unique context to study management processes relating to strategy but so far, despite the emergence of the concept, there has not been a coherent approach identifiable in the literature. It is recognised that subsidiaries evolve over time and through their own actions and initiatives have the potential to modify the power structures of the Multinational Enterprise (MNE) but little is known about the role of the subsidiary manager in this process. We suggest that …

Understanding Interaction Through The Lens Of Materiality And The Processual Nature Of Artifacts, Conor Horan, John Finch, Emma Reid

Conference papers

The elements and processes to understand organisational business-to-business interactions have been extensively explored. The context and forms these interactions takeunderpinmajor threads of research in the Markets-as-Networks tradition of understanding business networks. Standard operating procedures (SOPs), job specs, contracts andbriefs as physical objects play material roles within these business-to-business interactions, guiding and managing how these relationships play out. This paper primarily builds on the rich Markets-as-Networks tradition by refocusing attention on the role artifacts play in the interaction process. In addition there appears to be non-material artifacts, without physical forms, that also aid in guiding and managing interactions. This paper incorporates …

Extending A Mobile Device's Interaction Space Through Body-Centric Interaction, Xiang Chen, Nicolai Marquardt, Anthony Tang, Sebastian Boring, Saul Greenberg

Research Collection School Of Computing and Information Systems

Modern mobile devices rely on the screen as a primary input modality. Yet the small screen real-estate limits interaction possibilities, motivating researchers to explore alternate input techniques. Within this arena, our goal is to develop Body-Centric Interaction with Mobile Devices: a class of input techniques that allow a person to position and orient her mobile device to navigate and manipulate digital content anchored in the space on and around the body. To achieve this goal, we explore such interaction in a bottom-up path of prototypes and implementations. From our experiences, as well as by examining related work, we discuss and …

Setting The Bar For "Injury" In Environmental Exposure Cases: How Low Can It Go?, John C. Cruden, Carla Burke, John Guttmann, Robert V. Percival

Faculty Scholarship

On May 16, 2012, ELI convened a panel of experts to provide an overview and analysis of the tension between regulatory and common-law standards for injury in the context of toxic tort litigation. The speakers discussed and debated emerging trends in toxic tort litigation, including claims for property damage or medical monitoring regarding exposure to environmental contamination that never exceeds applicable regulatory standards. The panel also analyzed recent court opinions on the bounds of "injury" in environmental contamination cases and the potential for plaintiffs to recover damages based upon relatively low concentrations of chemicals. Issues explored by the panel included …

Agricultural Secrecy: Going Dark Down On The Farm: How Legalized Secrecy Gives Agribusiness A Federally Funded Free Ride, Rena I. Steinzor, Yee Huang

Faculty Scholarship

This briefing paper examines the agricultural secrecy granted by section 1619 of the 2008 Farm Bill, its implications for transparency and oversight, and its impact on other federal agencies such as the U.S. Environmental Protection Agency (EPA). In an era of fiscal responsibility, tight budgets, and increasing pressure on the environment, the public has a right to know whether the U.S. Department of Agriculture (USDA) is making the best decisions about how to allocate public funds.

Each year, agricultural producers in the United States receive billions of dollars in federal payments: crop subsidies, crop insurance, conservation payments, disaster payments, loans, …

Leveraging Whole Life Cycle Costs When Utilising Building Information Modelling Technologies, Barry Mcauley, Dermot Kehily, Alan Hore

Conference papers

Building Information Modelling (BIM) is now being increasingly used as a technology tool to assist design professions in conceiving, designing, constructing, and operating the built environment in many countries. The BIM model provides design professions with the framework to perform exercises in design, programming, cost and value management, and concept energy analysis, in order to achieve the most economical and sustainable building solution. The BIM model though sophisticated is not extensively used to provide estimation software with the data requirements for Life Cycle Costing (LCC), such as, escalation of future expenditure and/or present value costs, discount rates, and study periods. …

Velocity-Selective Direct Frequency-Comb Spectroscopy Of Atomic Vapors, Jason E. Stalnaker, S. L. Chen, M. E. Rowan, K. Nguyen, T. Pradhananga, C. A. Palm, Derek F. Jackson Kimball

Faculty & Staff Scholarship

We present an experimental and theoretical investigation of two-photon direct frequency-comb spectroscopy performed through velocity-selective excitation. In particular, we explore the effect of repetition rate on the 5S_1/2 → 5D_3/2,5/2 two-photon transitions excited in a rubidium atomic vapor cell. The transitions occur via stepwise excitation through the 5P_1/2,3/ states by use of the direct output of an optical frequency comb. Experiments were performed with two different frequency combs, one with a repetition rate of ≈ 925 MHz and one with a repetition rate of ≈ 250 MHz. The experimental spectra are compared to each …

A Renewed Approach To Undergraduate Worship Leader Education, Allen Hendricks

Doctoral Dissertations and Projects

The church music degree program at Charleston Southern University, based on a European traditional/classical sacred music degree model, has been attracting fewer and fewer students. The last two students pursuing this degree were graduated in May, 2011. Prior to their graduation, the administration encouraged the music department to investigate current career markets and the worship leadership training strategies of other institutions. The purpose of this project is to design a suitable worship leadership degree and thus assist the university in its mission to equip churches with properly trained ministry leaders. Survey instruments will be used to discover the expectations of …

The Status Of Teachers Unions: Are Rumors Of Their Demise Exaggerated?, Charles J. Russo

Educational Leadership Faculty Publications

Recent legislation raised questions about the status of teachers unions and public-sector collective bargaining. Although the changes in Florida, Idaho, and Tennessee occurred with a minimum of disruption, the same was not true in Ohio and Wisconsin. Voters in Ohio repudiated a law that would have placed significant limits on the rights of public employees to bargain collectively (McNeil 2011a). Conversely, voters in Wisconsin defeated a recall election intended to remove the governor and legislators who acted to curtail the bargaining power of teachers unions (Stein 2012).

Organized labor and collective bargaining in education have grown to the point at …

Stochastic Reactor Modelling Of Multi Modes Combustion With Diesel Direct Injection Or Hydrogen Jet Ignition Start Of Combustion, Alberto A. Boretti

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Recent papers [1-5] have proposed two different systems to more efficiently and more rapidly burn the fuel in highly boosted, high compression ratio, directly injected internal combustion engines permitting multi-mode combustion operation. in a first system, a second direct injector is coupled with the standard Diesel direct injector and glow plug. the second direct injector introduces most of the fuel while the Diesel direct injector only introduces a minimum amount of fuel to control the start of the combustion about top dead center. the fuel injected before the Diesel ignition injection burns premixed, the fuel injected after the Diesel ignition …

Erratum: Search For Gravitational Waves From Binary Black Hole Inspiral, Merger, And Ringdown (Physical Review D - Particles, Fields, Gravitation And Cosmology (2011) 83 (122005)), J. Abadie, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

Since the publication we have discovered two errors in the calculation of upper limits on binary black hole (BBH) coalescence rates inferred from the nondetection of gravitational waves. The errors caused systematic biases of opposite signs and different sizes in the 90% confidence rate limits; when errors are corrected, the resulting limits are a factor 3 to 5 smaller than those quoted. Here we give a brief description of the errors and report their impacts on the upper limit results.

We present a novel experimental tool allowing for kinematically complete studies of break-up processes of laser-cooled atoms. This apparatus, the 'MOTReMi,' is a combination of a magneto-optical trap (MOT) and a reaction microscope (ReMi). Operated in an ion-storage ring, the new setup enables us to study the dynamics in swift ion-atom collisions on an unprecedented level of precision and detail. In the inaugural experiment on collisions with 1.5MeV/amu O8 ⁺-Li the pure ionization of the valence electron as well as the ionization-excitation of the lithium target was investigated.

Non-Fermi Liquid Transport And "Universal" Ratios In Quantum Griffiths Phases, David Nozadze, Thomas Vojta

Physics Faculty Research & Creative Works

We use the semi-classical Boltzmann equation to investigate transport properties such as electrical resistivity, thermal resistivity, thermopower, and the Peltier coefficient of disordered metals close to an antiferromagnetic quantum phase transition. In the quantum Griffiths phase, the electrons are scattered by spin-fluctuations in the rare regions. This leads to singular temperature dependencies not just at the quantum critical point, but in the entire Griffiths phase. We show that the resulting non-universal power-laws in transport properties are controlled by the same Griffiths exponent λ which governs the thermodynamics. λ takes the value zero at the quantum critical point and increases throughout …

Production Scheduling And Waste Disposal Planning For Oil Sands Mining Using Goal Programming, E. Ben-Awuah, H. Askari-Nasab, Kwame Awuah-Offei

Mining Engineering Faculty Research & Creative Works

In oil sands mining, timely provisions of ore and tailings containment with less environmental footprints are the main drivers of profitability and sustainability. The recent Alberta Energy Resources Conservation Board Directive 074 requires oil sands waste disposal planning to be an integral part of mine planning. This requires the development of a well integrated strategy of directional mining and tailings dyke construction for in-pit and ex-pit tailings storage management. The objectives of this paper are to: 1) determine the order and time of extraction of ore, dyke material and waste that maximizes the net present value; 2) determine the destination …

A Method To Generate Pressure Gradients For Molecular Simulation Of Pressure-Driven Flows In Nanochannels, Zhi Liang, Hai-Lung Tsai

Mechanical and Aerospace Engineering Faculty Research & Creative Works

One of the Difficulties in Molecular Simulation of Pressure-Driven Fluid Flow in Nanochannels is to Find an Appropriate Pressure Control Method. When Periodic Boundary Conditions (PBCs) Are Applied, a Gravity-Like Field Has Been Widely Used to Replace Actual Pressure Gradients. the Gravity-Fed Method is Not Only Artificial, But Not Adequate for Studying Properties of Fluid Systems Which Are Essentially Inhomogeneous in the Flow Direction. in This Paper, a Method is Proposed Which Can Generate Any Desired Pressure Difference to Drive the Fluid Flow by Attaching a "Pump" to the Nanofluidic System, While the Model is Still Compatible with PBCs. the …
