Chronology Of Sediment Deposition In Upper Klamath Lake, Oregon, Steven M. Colman, J. Platt Bradbury, John P. Mcgeehin, Charles W. Holmes, David Edginton, Andrei M. Sarna-Wojcicki

United States Geological Survey: Staff Publications

A combination of tephrochronology and ¹⁴C, ²¹⁰Pb, and ¹³⁷Cs measurements provides a robust chronology for sedimentation in Upper Klamath Lake during the last 45 000 years. Mixing of surficial sediments and possible mobility of the radio-isotopes limit the usefulness of the ¹³⁷Cs and ²¹⁰Pb data, but ²¹⁰Pb profiles provide reasonable average sediment accumulation rates for the last 100–150 years. Radiocarbon ages near the top of the core are somewhat erratic and are too old, probably as a result of detrital organic carbon, which may have become a more common component in recent times as …

Limnological And Climatic Environments At Upper Klamath Lake, Oregon During The Past 45 000 Years, J. Platt Bradbury, Steven M. Colman, Walter E. Dean

United States Geological Survey: Staff Publications

Upper Klamath Lake, in south-central Oregon, contains long sediment records with well-preserved diatoms and lithological variations that reflect climate-induced limnological changes. These sediment archives complement and extend high resolution terrestrial records along a north–south transect that includes areas influenced by the Aleutian Low and Subtropical High, which control both marine and continental climates in the western United States. The longest and oldest core collected in this study came from the southwest margin of the lake at Caledonia Marsh, and was dated by radiocarbon and tephrochronology to an age of about 45 ka. Paleolimnological interpretations of this core, based upon geochemical …

Grassland Vegetation And Bird Communities In The Southern Great Plains Of North America, Robert N. Chapman, David M. Engle, Ronald E. Masters, David M. Leslie Jr.

United States Geological Survey: Staff Publications

Structure and composition of vegetation and abundance of breeding birds in grasslands seeded to Old World bluestem (Bothriochloa ischmaeum) were compared to native mixed prairie in the southern Great Plains of North America. Abundance of birds was determined using fixed-radius point counts. Detrended correspondence analysis was used to compare plant community composition and canonical correspondence analysis was used to examine the relationships between plant species composition and vegetation structure with the bird community. Plant species composition differed distinctly between seeded grassland and native mixed prairie, but the differences were not reflected in habitat structure, bird community composition, or …

Reduced Acetylcholine Receptor Density, Morphological Remodeling, And Butyrylcholinesterase Activity Can Sustain Muscle Function In Acetylcholinesterase Knockout Mice, Michael Adler, Heather A. Manley, Angela L. Purcell, Sharad S. Deshpande, Tracey A. Hamilton, Robert K. Kan, George Oyler, Oksana Lockridge, Ellen G. Duysen, Robert E. Sheridan

United States Army: Publications

The vertebrate neuromuscular junction is designed for rapid transmission of excitatory signals for initiation of muscle contraction.5 Among the features responsible for the high throughput of this synapse are the close proximity of the presynaptic and postsynaptic membranes,10 the direct coupling of acetylcholine (ACh) binding to the opening of the ion channel associated with the nicotinic acetylcholine receptor (nAChR),27 the brief open time of this channel,21,27 and the presence of cholinesterase (ChE) for hydrolysis of ACh.21,30 At the endplate, there are two distinct ChEs for transmitter hydrolysis: acetylcholinesterase (EC 3.1.1.7, AChE) and butyrylcholinesterase (EC 3.1.1.8, BChE).33 Both enzymes can …

K-4 Pre-Service Classroom Teachers' Beliefs About Useful Skills, Understandings And Future Practice In Music, Francine Morin

Research & Issues in Music Education

The purpose of this study was to investigate K-4 pre-service classroom teachers’ beliefs about useful skills, understandings, and future practices in music. Questionnaire (N=74) and interview (N=35) data were gathered from teacher candidates enrolled in music methods courses at a large, western Canadian university. Music skills and understandings such as singing, listening, and integrating music across other subject areas were rated as "most useful," indicating a definite valuing of pedagogical content knowledge over content knowledge like music fundamentals, music history, or playing accompaniment instruments. Future music practices discussed by pre-service teachers were closely aligned to the beliefs they hold about …

Comparing Two Approaches For Teaching Rhythm Reading Skills To First-Grade Children: A Pilot Study, Delores Gauthier, Robert E. Dunn

Research & Issues in Music Education

This pilot study compared two approaches for teaching rhythm reading skills to first-grade children. Two intact first-grade classes participated in six lessons focusing on simple rhythms (4 beats using eighth and quarter notes). The lessons were based on the same musical materials; only the approach was varied. After random assignment, Class 1 experienced the “Subdivision Approach” where the quarter note is the beat, and eighth notes are subdivisions of the beat. Class 2 used the “Additive Approach” where, in this case, the eighth note is the “shortest sound” and a quarter note is the equivalent of two short sounds.

Turkish Journal of Physics

A low-latitude anticenter field (l = 189°, b = +21°) is investigated by using the full calibration tools of RGU photometry. The observed RGU data are reduced to the standard system and the separation of dwarfs and evolved stars is carried out by an empirical method. Stars are categorized into three metallicity classes, i.e. -0.25

Gore's Metamorphosis In State Farm V. Campbell: When Guideposts Make A Detour, Anthony Geraci

St. Thomas Law Review

This paper discusses the significance of State Farm v. Campbell and how it removes what little effectiveness punitive damage awards were left with after Leatherman.1 Part II briefly explores the past of punitive damages and explains the modem jurisprudence of punitive damages in America. Part III sets forth State Farm v. Campbell. Part IV, Section A argues that State Farm has removed the deterrence function from punitive damages because the Court has given corporations all the tools they need to make an effective cost/benefit analysis. Furthermore, State Farm has removed the punishment function from punitive damages because it has instituted …

Mpdls Is Not A Disease: A Proposition For A Model Punitive Damage Limiting Statute In Light Of The Constitutional Guideposts From Bmw And State Farm, Christopher Price

St. Thomas Law Review

What would a football game be without the first down marker? Perhaps it would result in confusion, frustration and ultimately an arbitrary decision by a referee to determine what is and what is not a first down. In the same vein as a football game played without first down markers, a court attempting to impose punitive damages without clear and distinguished markers will likely render inconsistent and perhaps even unfair decisions. The United States Supreme Court in State Farm v. Campbell' ignored an opportunity to establish a bright-line test for lower courts to confidently impose punitive damages without running afoul …

The State Farm Punitive Damage Multiplier In The Courts: Early Returns, Charles S. Doskow

St. Thomas Law Review

On May 22, 1981, on a two-lane highway in rural Utah, Curtis Campbell attempted to pass six tractor-trailers.' He was not successful. When the wreckage cleared, the driver of an oncoming car was dead, the driver of one of the cars in line ahead of him was paralyzed, and the United States Supreme Court's punitive damages jurisprudence suddenly exploded. In one fell swoop, the United States Supreme Court, with the aid of the bad faith of State Farm Mutual Automobile Insurance Company ("State Farm"), led by the editorial page of the Wall Street Journal, accomplished what the business community of …

Fire In Southern Appalachians: Fuels, Stand Structure And Oaks, David L. Loftis, Mary A. Arthur, Rex Mann, Jeffrey Lewis

Joint Fire Science Program Research Project Reports

Managers responsible for maintaining the diversity and productivity of Southern Appalachian forests are increasingly turning to prescribed fire as an important management tool in oak dominated forests. The decision to use fire with increasing frequency and spatial extent is based, in part, on an emerging sense of the prehistoric significance of fire in this landscape and its potential to control the proliferation of fire-sensitive competitors in contemporary forests. While it is well documented that fire has been an important ecological force in Southern Appalachian forests for a very long time, there has been little research to demonstrate that prescribed fire …

Smart Materials, Precision Sensors/Actuators, Smart Structures, And Structronic Systems, H. S. Tzou, H.-J. Lee, S. M. Arnold

United States National Aeronautics and Space Administration: Publications

Many electroactive functional materials have been used in small- and microscale transducers and precision mechatronic control systems for years. It was not until the mid-1980s that scientists started integrating electroactive materials with large-scale structures as in situ sensors and/or actuators, thus introducing the concept of smart materials, smart structures, and structronic systems. This paper provides an overview of present smart materials and their sensor/actuator/structure applications. Fundamental multifield optomagnetopiezoelectric-thermoelastic behaviors and novel transducer technologies applied to complex multifield problems involving elastic, electric, temperature, magnetic, light, and other interactions are emphasized. Material histories, characteristics, material varieties, limitations, sensor/actuator/structure applications, and so forth …

Response Of Nebraska Sand Hills Natural Vegetation To Drought, Fire, Grazing, And Plant Functional Type Shifts As Simulated By The Century Model, Jennifer Mangan, Jonathan T. Overpeck, Robert S. Webb, Carol Wessman, Alexander Goetz

School of Natural Resources: Faculty Publications

The Nebraska Sand Hills exist in a semi-arid climatic environment and the land surface is grassland growing on sandy soils. These soils have been periodically active throughout the Holocene, but are currently stabilized by the vegetation. However, a shift in climate could cause grassland death and eventual sand dune remobilization. Our studies used the CENTURY nutrient cycling and ecosystem model to investigate the impacts of drought, plant functional type, fire, grazing, and erosion on Nebraska Sand Hills vegetation and dune stability. Fire and grazing alone had little impact on the vegetation, but when combined with mild drought, biomass decreased. Overall …

A Self-Calibrating Palmer Drought Severity Index, Nathan Wells, Steve Goddard, Michael Hayes

School of Natural Resources: Faculty Publications

The Palmer Drought Severity Index (PDSI) has been used for more than 30 years to quantify the long-term drought conditions for a given location and time. However, a common critique of the PDSI is that the behavior of the index at various locations is inconsistent, making spatial comparisons of PDSI values difficult, if not meaningless.

A self-calibrating Palmer Drought Severity Index (SC-PDSI) is presented and evaluated. The SC-PDSI automatically calibrates the behavior of the index at any location by replacing empirical constants in the index computation with dynamically calculated values. An evaluation of the SC-PDSI at 761 sites within Nebraska, …
