Design And Evaluation Of A Suspension Seat To Reduce Vibration Exposure Of Subway Operators: A Case Study, Pierre Marcotte, Sylvie Beaugrand, Jérôme Boutin, Christian Larue

Études primaires

Subway operators have complained about discomfort caused by whole-body vibration. To address this problem, a suspension seat with extensive ergonomic features has been adapted to the confined space of the subway operator cab. The suspension was modified from an existing suspension in order to reduce the dominant frequency of the subway vertical vibration (2.4 Hz). The suspension seat has been extensively tested on a vertical hydraulic shaker. These tests have shown that the SEAT value was lower for a higher vibration level, for higher subject weight, and for the suspension adjusted at median height. The seat also produces a lower …

Resisting Technological Gravity: Using Guiding Principles For Instructional Design, Jason K. Mcdonald

Faculty Publications

Instructional designers face tremendous pressure to abandon the essential characteristics of educational approaches, and settle instead for routine practices that do not preserve the level of quality those approaches originally expressed. Because this pressure can be strong enough to affect designers almost as gravity affects objects in the physical world, the metaphor of technological gravity has been proposed to describe why designers choose one type of practice over another. In this essay, I discuss how designers can develop guiding principles to help them resist technological gravity. I describe three types of principles, in the areas of what instruction is, …

Plasma Pharmacokinetics And Tissue Disposition Of Novel Dextran- Methylprednisolone Conjugates With Peptide Linkers In Rats, Suman Penugonda, Hitesh K. Agarwal, Keykavous Parang, Reza Mehvar

Pharmacy Faculty Articles and Research

The plasma and tissue disposition of two novel dextran prodrugs of methylprednisolone (MP) containing one (DMP-1) or five (DMP-5) amino acids as linkers were studied in rats. Single 5-mg/kg doses (MP equivalent) of each prodrug or MP were administered intravenously, and blood and tissue samples were collected. Prodrug and drug concentrations were quantitated using HPLC, and noncompartmental pharmacokinetic parameters were estimated. Whereas conjugation of MP with dextran in both prodrugs substantially decreased the clearance of the drug by ∼200-fold, the accumulations of the drug in the liver, spleen, and kidneys were significantly increased by conjugation. However, the extent of accumulation …

Louder Speech Leads To Greater Intelligibility Improvements Than Amplification Of Habitual Speech In Parkinson Disease, Christopher Dromey

Faculty Publications

Amplification may be helpful in improving speech intelligibility for some speakers with Parkinson disease. Because the gain used in the present study was limited to the dB increase from habitual to loud speech, it is unclear how performance might increase with higher amplification levels. Increases in the signal to noise ratio in the present study only account for about one third to one half of the intelligibility improvements that accompany loud speech. Thus, loud speech differs from habitual speech in more than just its amplitude. Articulation appears to play a lesser role in these improvements, whereas source spectral changes may …

Bidirectional Interference Between Speech And Postural Stability In Individuals With Parkinson's Disease, Christopher Dromey, Eon Jarvis, Stuart Sondrup, Shawn Nissen, K. Bo Foreman, Leland E. Dibble

Faculty Publications

Because people frequently talk while engaged in other activities, and because Parkinson's disease (PD) is known to diminish multi-tasking performance, we examined dual task interference between speaking and postural stability in 9 individuals with PD, 7 age-matched and 10 healthy young controls. Participants repeated a target utterance and performed a rise to toes task in both single and dual task conditions. Diphthong transitions were measured from audio recordings and postural variables reflecting planning, coordination, and stability were derived from a multi-camera motion capture system and force plate recordings. Thus, sensitive measures of both control groups for the isolated postural task, …

Our Top 12 "Key Instructional Elements" That Help To Build An Excellent Lesson And High Quality Physical Education Program, Robert S. Christenson, David C. Barney

Faculty Publications

One of the most fundamental issues in teaching, arguably the biggest, is discovering the most effective lesson elements for each group of learners. This includes a solid curriculum, performance objectives, age-appropriate pedagogical ingredients, ability-level activities and assessments focused on measuring learning to create a great lesson. When these elements are blended artistically with a variety of classroom management skills, necessary equipment, instructional support resources, behavior management rules and high expectations in a nurturing environment, the teacher has created the best possible learning atmosphere for each individual student.

The Impact Of Monetary Regimes On International Trade Are Eu Experiences Relevant For Asia?, Apanard P. Angkinand, Clas Wihlborg

Business Faculty Articles and Research

We extend much research that has been devoted to the effects of the European Monetary Union (EMU) on international trade by introducing monetary regime variables in bilateral export equations with the objective of capturing the effects on trade of changes in monetary regimes relative to the pure EMU effects. To make the analysis relevant from an Asian perspective trade effects of the EU’s internal markets are also separated from EMU effects. To identify these different effects we include three groups of countries in our sample: EMU countries which are also members of the EU, EU countries outside the EMU and …

Financial Liberalization And Banking Crises: A Cross-Country Analysis, Apanard P. Angkinand, Wanvimol Sawangngoenyuang, Clas Wihlborg

Business Faculty Articles and Research

Several studies indicate that financial liberalization contributes to the likelihood of a financial crisis. We focus on banking crises and argue that they are most likely to occur after an intermediate degree of liberalization. Using a recently updated dataset for financial reforms in 48 countries between 1973 and 2005, we find an inverted U-shaped relationship between liberalization and the likelihood of crisis. We ask whether the relationship remains when institutional characteristics of countries and dynamic effects of liberalization are considered. The empirical results indicate that the relationship between liberalization and banking crises depends strongly on the strength of capital regulation …

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

This thesis details the design of an electric machine to perform as both a starter and alternator in a series hybrid electric vehicle. The focus of the work is on practical design aspects specific to single-sided axial flux permanent magnet machines with non-overlapped windings. First, a characterization of the rotor losses in these machine types is presented through experimental validation of finite element analysis estimates. The approaches taken to model the axial flux geometry, especially in two-dimensions, are detailed, and the difficult issue of validating the finite element analysis estimates with experimental data is addressed with a prototype 24-slot, 20-pole …

Modeling Biological Structures Via Abstract Grammars To Solve Common Problems In Computational Biology, David J. Russell

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Grammars are generally understood to be the set of rules that define the relationships between elements of a language. However, grammars can also be used to elucidate structural relationships within sequences constructed from any finite alphabet. In this work abstract grammars are used to model the primary and secondary structures present in biological data. These grammar models are inferred and applied to efficiently solve various sequence analysis problems in computational biology, including multiple sequence alignment, fragment assembly, database redundancy removal, and structural prediction.

The primary structures, or sequential ordering of symbols, of biological data are first modeled with Lempel-Ziv (LZ) …

Growth And Characterization Of Silicon Carbide Thin Films Using A Nontraditional Hollow Cathode Sputtering Technique, James Huguenin-Love

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Silicon carbide (SiC) is considered a suitable candidate for high-power, high-frequency devices due to its wide bandgap, high breakdown field, and high electron mobility. It also has the unique ability to synthesize graphene on its surface by subliming Si during an annealing stage. The deposition of SiC is most often carried out using chemical vapor deposition (CVD) techniques, but little research has been explored with respect to the sputtering of SiC.

Investigations of the thin film depositions of SiC from pulse sputtering a hollow cathode SiC target are presented. Although there are many different polytypes of SiC, techniques are discussed …

The Work-Family Interface In The United States And Singapore: Conflict Across Cultures, Adam M. Galovan, Tamara Fackrell, Lydia Buswell, Blake L. Jones, E. Jeffrey Hill, Sarah June Carroll

Faculty Publications

This article examines the work–family interface in a cross-cultural comparison between two nationally representative samples from the United States (n 􏰀 1,860) and Singapore (n 􏰀1,035) with emphasis on work–family conflict. Family-to-work conflict was negatively related to marital satisfaction in both Singapore and the United States, although the effect was stronger in the United States. Similarly, family-to-work conflict was positively related to job satisfaction in the United States but was negatively related in Singapore. As expected, schedule flexibility was negatively related to depression in the United States, but in Singapore the relationship was positive. These findings suggest that theoretical relationships …

Coping activities included a variety of tasks and were performed by individuals, by both spouses in a shared effort, …

Experimental Investigation Of Dielectric Barrier Impact On Breakdown Voltage Enhancement Of Copper Wire-Plane Electrode Systems, Elham Foruzan, M. Ziaee-Nezhad, A. A. Shayegani-Akmal, K. Niayesh

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Non-pressurized air is extensively used as basic insulation media in medium / high voltage equipments. An inherent property of air-insulated designs is that the systems tend to become physically large. Application of Dielectric barrier can increase the breakdown voltage and therefore decrease the size of the equipments.

In this paper, the impact of dielectric barrier on breakdown voltage enhancement of a copper wire-plane system is investigated. For this purpose, the copper wire is covered with different dielectric materials. Depending on the air gap and dielectric strength of the barrier the breakdown can be initiated in the solid or gas dielectric. …

The Need For Evidence-Based, Spiritually Oriented Psychotherapies, P. Scott Richards, Everett L. Worthington Jr.

Faculty Publications

Despite a proliferation of spiritually oriented psychotherapies during the past 2 decades in the mental health professions, outcome research is lacking. In this present article, 6 published outcome reviews that shed light on the efficacy of these psychotherapies are discussed. Although there is general support for the efficacy of spiritually oriented treatment approaches, the data base is relatively small and has methodological limitations. Spiritually oriented cognitive approaches for religious clients with depression and anxiety meet evidence- based standards of efficacy. Several other spiritually oriented approaches are probably efficacious but need additional investigation. Methodological recommendations for improving the quality of future …

Book Review: Smith, J.K.A.: Desiring The Kingdom: Worship, Worldview, And Cultural Formation, Christina Belcher

International Christian Community of Teacher Educators Journal

What if education was not first and foremost about what we know, but about what we love? (Smith, 2009, p.18)

This is one of the driving questions that frames Smith’s book; a question worthy of educational reflection. Smith organizes his argument around the ideas of the dichotomy between thinking and doing; work and worship [liturgy]. His argument is that worldview must not be merely cognitive and intellectual, but must include a robust ‘social imaginary’ (flowing from the work of Charles Taylor) that is grounded in the practices of Christian worship. So far so good.
