Displaying Group Cohesiveness: Humour And Laughter In The Public Lectures Of Management Gurus, David Greatbatch, Timothy Adrian Robert Clark

Research Collection Lee Kong Chian School Of Business

As perhaps the highest profile group of management speakers in the world, so-called management gurus use their appearances on the international management lecture circuit todisseminate their ideas and to build their personal reputations with audiences of managers. This article examines the use of humour by management gurus during these public performances. Focusing on video recordings of lectures conducted by four leading management gurus (Tom Peters, Rosabeth Moss Kanter, Peter Senge and Gary Hamel), the article explicates the verbal and nonverbal practices that the gurus use when they evoke audience laughter. These practices allow the gurus to project clear message completion …

Seasonal Movements Of Yellow-Phase American Eels ( Anguilla Rostrata) In The Shenandoah River, West Virginia, Stephen D. Hammond

Graduate Theses, Dissertations, and Problem Reports (ETD)

American eels undergo extensive upstream migration in Atlantic coastal river systems. Few studies, however, have focused on movements of large yellow-phase American eels near dams in upper watersheds of Atlantic coastal rivers. We examined relationships between stream flow, water temperature, and lunar phase, and movements of radio-tagged yellow-phase American eels (518--810 mm TL) near Millville hydroelectric dam in the lower Shenandoah River, West. Movements of yellow-phase American eels differed among seasons. Water temperature and stream flow were associated with upstream migration during spring. Downstream movements during fall corresponded with decreasing water temperatures and darker nights near the new moon. Localized …

Aquaculture-Related Stress On Rainbow Trout (Oncorhynchus Mykiss) And Arctic Char (Salvelinus Alpinus), Christopher D. Nelson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Recent expansions in aquaculture characterize it as one of the fastest growing segments of the U.S. agricultural sector. Expansion has been facilitated by increased production of many important aquatic species including catfish, salmon, trout, tilapia, shrimp, oysters, and crawfish. West Virginia aquaculture, also an expanding industry, is currently characterized by small-scale, widely dispersed farms. To facilitate future expansion of aquaculture in West Virginia, focuses on product quality as well as production efficiency, identification of limiting factors and investigation into new or alternative management techniques are needed. Objectives of this project were to determine the effects of nitrite and carbon dioxide …

Enhancing Quality And Extending Shelf Life Of Rainbow Trout (Oncorhynchus Mykiss) By Vitamin E Supplementation And Post-Harvest Antimicrobial Intervention, Nalini Kamireddy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rainbow trout were fed a control (191 mg/kg) or the control diet supplemented with 5000 mg alpha-tocopherol/kg. Fish were sampled at 2, 3, 4, 5, 7, and 9 weeks of feeding; at each week fillets were evaluated at 0, 7, and 14 d. Supplementation increased fillet alpha-tocopherol content, and TBARS value were not affected. A feeding by storage time interaction was observed for fat content, psychrotrophic counts, cook yield, and shear force. For antimicrobial intervention, fillets were not treated or were dipped in water, 50 ppm ASC, and 1000 ppm ASC for 30 s. Fillets were stored at 1--2°C for …

Brook Trout (Salvelinus Fontinalis) Movement And Habitat Use In A Headwater Stream Of The Central Appalachian Mountains Of West Virginia, Marisa Nel Logan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Brook trout (Salvelinus fontinalis) are the only salmonid native to the Appalachians. They are a resilient species, populating small, low productive streams. Although such streams have historically been abundant in the Appalachians, brook trout populations have been threatened due to habitat degradation such as logging and acidification of waters. The objective of this study was to evaluate brook trout habitat use, home range, and movement patterns in an Appalachian headwater stream during spring and more specifically high flow events. I implanted brook trout with radio tags and tracked their movement for approximately 30 days during late spring 2002 and early …

Population Level Dynamics Of Grasshopper Sparrow Populations Breeding On Reclaimed Mountaintop Mines In West Virginia, Frank K. Ammer

Graduate Theses, Dissertations, and Problem Reports (ETD)

During 2001 and 2002, I surveyed three mountaintop mining/valley fill (MTMVF) complexes in southern West Virginia to determine vegetation characteristics important to nest site selection and to estimate nest success for Grasshopper Sparrow populations inhabiting these complexes. I also performed genetic analyses to assess overall population structure, mating system, parentage, kinship, and gender of individuals comprising these populations. A total of 415 grasshopper sparrows were captured and systematic searches of study plots produced 75 active nests. Nest survival for 2001--2002 breeding season (33%) is comparable to survival rates previously reported in the literature. Nest survival rates decreased with increased reclamation …

Metallothionein Isoform 3 Expression In Human Bladder Urothelium, Seongmi Park

Graduate Theses, Dissertations, and Problem Reports (ETD)

The third isoform of metallothionein, MT-3 is shown to have a restricted pattern of tissue distribution with expression confined to the neural tissue. Previous work done by this laboratory has shown that MT-3 is not expressed in the normal bladder but is over-expressed in bladder cancer with levels correlating to the type and grade of tumor. Recently, a new bladder epithelial cell line UROtsa has been characterized that does not express the MT-3 gene and may serve as a useful in vitro model system of the normal human urothelium. The goal of this study was to see the effect of …

On The Contribution Of Mmp-2 And Mmp-9 To The Postnatal Cerebellar Corticogenesis, Albert E. Ayoub

Graduate Theses, Dissertations, and Problem Reports (ETD)

The development of the cerebellar cortex is dependent on orchestrated cell-cell, cell-matrix interactions, as well as intrinsic genetic programs. Matrix metalloproteinases (MMPs) are proteolytic enzymes that degrade ECM molecules and are involved in neuronal migration, process extension, and synaptic plasticity. The current study investigated (1) the developmental expression and activity of MMP-2 and MMP-9, and (2) the effect of blocking the activity of MMP-2 and MMP-9 by a specific inhibitor on the histogenesis of the cerebellar cortex. Cerebella were collected from rat pups every three days starting at postnatal day 3 (P3) until P25---a period equivalent to the third gestational …

Effects Of Fasting And Transportation On Pork Quality Development And Extent Of Postmortem Metabolism, J.M. Leheska, D.M. Wulf, R.J. Maddock

Animal Science Faculty Publications

One hundred seventy-seven pigs were used to determine the interaction effects of fasting and length of transport prior to harvest on pork muscle quality. The study design was a 2 × 2 × 3 factorial, which involved two genetic sources, fasting (F) or no fasting (N) of pigs 48-h prior to harvest, and three transport times (0.5, 2.5, or 8.0 h) on a semitrailer to the packing plant. Genetic source was a significant source of variation (P < 0.05) for most composition and muscle quality variables. Fasting reduced hot carcass weight 3.6% (P < 0.05), but length of transport did not affect hot carcass weight (P > 0.05). There were no differences (P > 0.05) in percent lean among fasting and transport treatments. Fasted pigs had higher longissimus dorsi (LD) ultimate …

Potential Field Theory And Its Applications To Classical Mechanical Problems, Shannon Rae Stillwagon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advances in many scientific fields are expected to come from work in nanotechnology. Engineering at nano-scales presents novel problems that classical mechanics cannot solve. Many engineers are uncomfortable designing at this level because classical or continuum mechanics does not apply and quantum mechanics is said to apply in a tangible way. There are unique opportunities to contribute to the design, controls, and analysis of systems that are particularly suited to mechanical engineering. Within the derivations of classical mechanics are assumptions that limit its use to bulk engineering. These assumptions are examined to determine what principles can be extended to smaller …

Distributed Dispatchers For Partially Clairvoyant Schedulers, Kiran S. Yellajyosula

Graduate Theses, Dissertations, and Problem Reports (ETD)

This work focuses on the empirical evaluation of distributed dispatching strategies on shared and distributed memory architectures for hard real-time systems. The dispatching model accommodates process parameter variability and analyzes the effect of variable execution times.;Hard real-time systems are modeled in the E-T-C scheduling framework and dispatched if a valid schedule exists. We examine the dispatchability of Partially Clairvoyant schedules of different sizes and varying deadlines under reasonable assumptions. The effect of scaling up the number of processors used by the dispatcher is also studied. The results validate the superiority of the distributed strategies over sequential dispatching and scalability of …

Evaluating Runoff Water Quality And Ammonia Volatilization In Three Turkey Litter Application Methods, Michael Dale Shamblin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Poultry litter is an important nutrient source in crop production. However, the traditional practice of broadcasting poultry litter on the soil surface could result in nutrient losses in runoff as well as substantial ammonia volatilization losses, which could adversely affect both the environment and agricultural productivity. This research compared nutrient runoff (natural and simulated) losses on 1 m x 2 m plots and ammonia volatilization from different turkey litter application methods (broadcast, surface-banded, incorporated band, and control) applied in triplicate. No significant differences were observed between any of the treatments in any of the runoff constituents measured. Over three runoff …

Soil Characterization, Classification, And Biomass Accumulation In The Otter Creek Wilderness, Jamie Schnably

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study evaluated soils of the Otter Creek Wilderness in the Monongahela National Forest. Thirteen sites were sampled and analyzed according to landscape position: three terrace soils (T), four ridgetop soils (R), three sideslope soils with argillic horizons (SSA), and three sideslope soils with cambic horizons (SSC). At each site, one pedon was described and sampled, and biomass data were collected. Standard chemical and physical properties, clay mineralogy, extractable sulfate and sulfated adsorption capacity were analyzed. The SSA soils had the highest pH, the most diverse vegetation, and the highest base saturation. These soils had a low risk for acid …

Effect Of Background Synaptic Activity On Excitatory-Postsynaptic Potential-Spike Coupling, Veronika Zsiros

Theses and Dissertations (ETD)

Neurons receive large amount of synaptic inputs in vivo, which may impact the coupling between EPSPs and spikes. We mimicked the in vivo synaptic activity of the cell with the dynamic clamp system. We recorded from pyramidal cells in neocortical slices in vitro to investigate how timing and probability of spike generation in response to an EPSP is affected by background synaptic conductance under these conditions. We found that near threshold, background synaptic conductance improved the precision of spike timing by reducing the depolarization-related prolongation of the EPSP. In cells with ongoing spike activity and background synaptic conductances, an …

Internal Phosphorus Loading In Spring Lake: Year 1, Dr. Alan Steinman, Dr. Rick Rediske

Scientific Technical Reports

The rate of phosphorus release from sediments, and the degree to which alum reduces phosphorus release from sediments, was investigated in Spring Lake during the summer of 2003. Triplicate cores were sampled from 4 sites in the lake, and exposed to one of four treatments in the laboratory: 1) oxygen/alum; 2) oxygen/ no alum; 3) nitrogen/alum; or 4) nitrogen/no alum. Both soluble reactive phosphorus (SRP) and total phosphorus (TP) release rates were virtually undetectable in the alum treatments (both with and without oxygen). Low, but detectable, release rates were measured in the oxygen/no alum treatment. The highest release rates were …

Dietary Feedback Effects And Gender Differences In Stages Of Change For Fat And Fiber Intake Behavior, Janis M. Boury

Graduate Theses, Dissertations, and Problem Reports (ETD)

The stages of change (SOC) model has addressed changes people make to important habits such as smoking or diet. This study had three purposes (a) examining the influence of cultural role expectations for males and females on decisional balance (DB), (b) examining changes in stage assignment following feedback for the hidden nutrients of fat and fiber, (c) comparing the effects of feedback and tailored messages on change in fat and fiber intakes.;This study was an experimental control group design with 273 participants at baseline, 235 at intervention, and 197 at post-intervention. Most participants had some college. Baseline included general and …

Rethinking Injury And Proximate Cause, John C.P. Goldberg

San Diego Law Review

Injury and proximate cause form two components of a plaintiff's prima facie negligence case. Although equals in this sense, they have received starkly different treatment at the hands of judges and scholars. Proximate cause has long attracted attention, yet has also managed to defy repeated efforts at characterization and explanation. Injury by contrast, seems to have been largely ignored. One of the many virtues of professor Perry's paper is that it prompts reconsideration of this disparate treatment from both ends. By offering a subtle and rich account of the related concept of "harm," Perry permits us to see that the …

Response Cost In The Treatment Of Lunging In Dogs, Jennifer L. Sobie

Masters Theses

Contemporary professional applied animal behavior management employs a diagnostic and treatment approach for unwanted pet behavior that incorporates ethology-based causal factors. As in behavior therapy for humans, behavioral assessment includes descriptive functional analysis when possible to determine relevant contingency variables. But this information is then considered in the context of an appropriate motivational classification, such as social or prey-directed motivation or fear-motivated, and treatments are designed accordingly. A different view is that behavior can be treated effectively without a presumption of the motivation through analysis of the manifestation of the behavior itself. This study sought to evaluate the efficacy of …

Shifting The Focus Of 4-H Record-Keeping From Competition And Subject Matter To Youth Development And Life Skills, Keith G. Diem, Annette Devitt

Journal of Extension

Youth can gain a lot of valuable knowledge and skills in 4-H, especially through 4-H clubs and long-term projects. But they typically don't recognize what they learn while participating. Record-keeping can help them realize more of the value of their involvement in clubs, camps, projects, and other educational activities. And record-keeping can also help Extension staff document the impact of their 4-H programs. A new format for record-keeping developed in New Jersey incorporates key elements deemed needed in a contemporary 4-H record book, including goal setting and reporting of life skills and S.C.A.N.S. workforce competencies.

Doorway, Doormat, Or Doghouse? The Challenges Facing 4-H Youth Development Scholarship In Land-Grant Universities, Kirk A. Astroth

Journal of Extension

Beginning with establishment of a 4-H professional research and knowledge base in 1986, to the recent launch of an on-line master's degree in youth development by a consortium of land-grant universities, to the implementation of the U.S. Department of Labor's certificate in youth development, youth development has attained recognition as a discipline with an identified academic base. Land-grant universities should join the effort to enhance the scholarship of 4-H youth development professionals, not stifle it. The challenge is to identify appropriate standards and definitions of scholarship. This article presents some of the challenges facing 4-H youth development scholarship in land-grant …
