A Survival Model For Unthinned Loblolly Pine Plantations That Incorporates Non-Planted Tree Competition, Site Quality, And Incidence Of Fusiform Rust, Dean W. Coble, Young-Jin Lee Jan 2002

A Survival Model For Unthinned Loblolly Pine Plantations That Incorporates Non-Planted Tree Competition, Site Quality, And Incidence Of Fusiform Rust, Dean W. Coble, Young-Jin Lee

Faculty Publications

Future biomass yields are functionally related to the number of trees surviving at a given age. A stand level survival model was developed that incorporates competition of non-planted trees, site quality, and the incidence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme). The model consists of a system of two equations, one of which represents the number of surviving trees infected by fusiform rust while the other represents the number of trees not infected by fusiform rust. Data from unthinned loblolly pine (Pinus taeda L.) plantations in East Texas were used to fit …

The Stephen F. Austin Experimental Forest, Cary C. Russell, Ronald E. Thill, David Kulhavy Jan 2002

The Stephen F. Austin Experimental Forest, Cary C. Russell, Ronald E. Thill, David Kulhavy

Faculty Publications

On December 14, 1944, the Seventy-Eighth United States Congress passed a bill that authorized the transfer of 2,560 acres in Nacogdoches County, Texas, to the research branch of the United States Forest Service (USFS). This land became the Stephen F. Austin Experimental Forest (SFAEF) on September 19. 1945. One of eighty-one federal experimental forests and ranges nationally, it is the only one of its kind in Texas. Located seven miles west of Nacogdoches, three quarters of the Forest consists of bottomland hardwood forests along the Angelina River and the remainder of mixed pine and hardwood uplands.

Soil Leachate Responses During 10 Years Of Induced Whole-Watershed Acidification, Pamela J. Edwards, James N. Kochenderfer, Dean W. Coble, Mary Beth Adams Jan 2002

Soil Leachate Responses During 10 Years Of Induced Whole-Watershed Acidification, Pamela J. Edwards, James N. Kochenderfer, Dean W. Coble, Mary Beth Adams

Faculty Publications

Soil solution was collected from zero-tension lysimeters for 10 yr on two small central Appalachian watersheds in West Virginia, U.S.A. Ammonium sulfate fertilizer was applied to one catchment 3 times per year during each year. The other watershed was used as a reference to account for ambient baseline conditions. Ca and Mg concentrations collected below the A- and B-horizons of the treated watershed increased and then decreased over time as a result of the treatment. By contrast, Ca and Mg concentrations in the C-horizon continued to increase throughout the study period.

Preliminary Results: Effects Of Fertilization, Herbicide Application, And Prescribed Burning On Understory Regeneration On Pine Plantations In East Texas, Betsy Ott, Brian Oswald, Hans Williams, Kenneth Farrish Jan 2002

Preliminary Results: Effects Of Fertilization, Herbicide Application, And Prescribed Burning On Understory Regeneration On Pine Plantations In East Texas, Betsy Ott, Brian Oswald, Hans Williams, Kenneth Farrish

Faculty Publications

Biodiversity and species rareness are increasingly the focal points for assessment of habitat quality. Managed pine plantations are often viewed as monocultures with little of value beyond their timber crop. The purpose of this study is to assess vegetative biodiversity in the understory of two pine plantations in which different vegetative control mechanisms are being evaluated. Controlled burn, herbicide treatment, and a combination of both are being compared on fertilized and unfertilized plots on two loblolly pine (Pinus taeda) plantations in east Texas. This study will compare species diversity and frequency on untreated and treated plots. One-square meter …

Crown area is an important factor in determining stem development. This study examined the changes in stem diameter per unit area of crown due to treatment with fire, herbicide, fertilizer, and tree-thinning practice. The experimental sites were mid-rotation loblolly pine (Pinus taeda) plantations that were thinned one year before treatment. Site 1 was strictly row-thinned and Site 2 was thinned by and within each row. Five replicates were installed on each site. Each replicate consisted of 8 subplots (0.1 ha) containing a central 0.04 ha measurement plot. A randomized-block split-plot design was used at each site, with fertilizer …

Effects Of Midrotation Intensive Silviculture On Forest Soils In East Texas: First-Year Results, S. A. Wilson, K. W. Farrish, B. P. Oswald, H. M. Williams, J. L. Yeiser

Faculty Publications

Intensive forest management is becoming increasingly common in east Texas. Included in intensive management are such practices as mid-rotation fertilization, prescribed fire, and herbicide application. There is insufficient information about the effects of these treatments on soil physical, chemical, and biological properties when applied at mid-rotation. The objectives of this research are to evaluate the effects of these treatments on soil physical properties including organic matter content and bulk density; chemical properties including soil nitrogen and phosphorus; and on populations of resident earthworms. Five replications were installed in each of two loblolly pine (Pinus taeda L.) plantations aged 15 …

Financial Maturity Concepts With Application To Three Hardwood Timber Stands, Steven H. Bullard, D. L. Grebner, K. L. Belli Jan 2002

Financial Maturity Concepts With Application To Three Hardwood Timber Stands, Steven H. Bullard, D. L. Grebner, K. L. Belli

Faculty Publications

Timber is “financially mature” when its rate of value increase falls below what the landowner can earn in alternative investments that are comparable in duration, risk, liquidity, and other factors. The basic concept of financial maturity is simple, but in application it involves several very important, basic questions and issues.

Innovate Or Evaporate . . . Business Concept Innovation In The Furniture Industry In The Age Of Information, Steven H. Bullard Jan 2002

Innovate Or Evaporate . . . Business Concept Innovation In The Furniture Industry In The Age Of Information, Steven H. Bullard

Faculty Publications

Introduction The U.S. furniture industry has changed dramatically in recent years. Furniture manufacturers, for example, have recently faced competition from foreign producers that has been particularly intense – resulting in factory closings and job losses in many areas of the country, including the Mid-South. In Mississippi, for example, the number of employees in furniture and fixtures industries dropped by 2,100 (6.8%) in the year 2000 (Center for Policy Research and Planning 2001). Similar job losses have been occurring in Tennessee, Virginia, North Carolina and other important furniture-producing states. Nationwide, employment in furniture and fixtures manufacturing dropped by 40,000 (7.2%) from …

Movement Patterns Of Resident And Relocated Northern Bobwhites In East Texas, Xiangwen Liu, R. Montague Whiting Jr., D. Scott Parsons, Donald R. Dietz Jan 2002

Movement Patterns Of Resident And Relocated Northern Bobwhites In East Texas, Xiangwen Liu, R. Montague Whiting Jr., D. Scott Parsons, Donald R. Dietz

Faculty Publications

We compared home range sizes and movement patterns of resident and relocated northern bobwhites (Colinus virginianus) on an area managed specifically for the species in the Pineywoods of east Texas. During the winters of 1990–1992, 155 south Texas, 136 east Texas, and 139 resident bobwhites were radiomarked, released, and thereafter regularly located. Bird locations were plotted on a digitized map, and home range sizes and movement patterns of each group of birds were estimated. Resident bobwhites moved longer daily distances in March and had larger home ranges during the nesting season (May-Jul) than relocated birds (P0.05). Managers that elect to …

Discount Rates For Nonindustrial Private Forest Landowners In Mississippi: How High A Hurdle?, Steven H. Bullard, Max L. Doolittle, Kathryn G. Arano Jan 2002

Discount Rates For Nonindustrial Private Forest Landowners In Mississippi: How High A Hurdle?, Steven H. Bullard, Max L. Doolittle, Kathryn G. Arano

Faculty Publications

Mississippi forest landowners were surveyed to determine average discount rates or “hurdle rates”—the lowest rates of return they consider acceptable—for 3 nonforestry investments, and for 5, 15, and 25 yr forestry investments. The survey included 829 individuals who owned at least 20 ac of uncultivated land and had harvested timber during a recent 5 yr period; survey results are therefore oriented toward commercially active forest landowners. On average, the private nonindustrial forest landowners included in the survey expect timberland investments to earn higher rates of compound interest than relatively low-risk bank savings accounts and certificates of deposit. Relatively short-term (5 …

Effect Of Ga Content On Defect States In Cuin1-XGaXSe2 Photovoltaic Devices, Jennifer T. Heath, J. David Cohen, William N. Shafarman, Dongxiang Liao, Angus Rockett Jan 2002

Effect Of Ga Content On Defect States In Cuin1-XGaXSe2 Photovoltaic Devices, Jennifer T. Heath, J. David Cohen, William N. Shafarman, Dongxiang Liao, Angus Rockett

Faculty Publications

Defects in the band gap of CuIn1-xGaxSe2 have been characterized using transient photocapacitance spectroscopy. The measured spectra clearly show response from a band of defects centered around 0.8 eV from the valence band edge as well as an exponential distribution of band tail states. Despite Ga contents ranging from Ga/(In+Ga)=0.0 to 0.8, the defect bandwidth and its position relative to the valence band remain constant. This defect band may act as an important recombination center, contributing to the decrease in device efficiency with increasing Ga content.

Sediment Denitrification In The Gulf Of Mexico Zone Of Hypoxia, C R. Childs, N N. Rabalais, R. Eugene Turner, L M. Proctor, C R. Childs Jan 2002

Sediment Denitrification In The Gulf Of Mexico Zone Of Hypoxia, C R. Childs, N N. Rabalais, R. Eugene Turner, L M. Proctor, C R. Childs

Faculty Publications

The largest zone of anthropogenic bottom water hypoxia in the Western Hemisphere occurs seasonally in the northern Gulf of Mexico between the Mississippi River delta and the coast of eastern Texas. This zone of hypoxia reaches its greatest extent in the summer months and is a consequence of seasonal stratification of the water column combined with the decomposition of organic matter derived from accelerated rates of primary production. This enhanced productivity is driven primarily by the input of inorganic nitrogen from the Mississippi River. There are 3 likely sinks for fixed nitrogen within this zone of hypoxia: sequestration in the …

Do Banks Price Owner–Manager Agency Costs? An Examination Of Small Business Borrowing, James C. Brau Jan 2002

Do Banks Price Owner–Manager Agency Costs? An Examination Of Small Business Borrowing, James C. Brau

Faculty Publications

Ang, Cole, and Lin (2000) provide evidence that supports the theoreticalwork of Jensen and Meckling (1976) on agency costs. As a further examination, I conduct a test to determine the economic significance of owner–manager agency conflicts. Using the same data source and empirical framework as Ang, Cole, and Lin (2000), I test to determine if banks chargeapremiumwhenextendingloans tofirmswith variousownership structures. In empirical tests, I find that banks do not require an owner–manager agency premium either through increased interest rates or through the requirement of collateral. Instead, I find that the interest rate is significantly affected by the length of the …

Peppering Knowledge Sources With Salt: Boosting Conceptual Content For Ontology Generation, Deryle W. Lonsdale, Yihong Ding, David W. Embley, Alan Melby Jan 2002

Peppering Knowledge Sources With Salt: Boosting Conceptual Content For Ontology Generation, Deryle W. Lonsdale, Yihong Ding, David W. Embley, Alan Melby

Faculty Publications

This paper describes work done to explore the common ground between two different ongoing research projects: the standardization of lexical and terminological resources, and the use of conceptual ontologies for information extraction and data integration. Specifically, this paper explores improving the generation of extraction ontologies through use of a comprehensive terminology database that has been represented in a standardized format for easy tool-based implementation. We show how, via the successful integration of these two distinct efforts, it is possible to leverage large-scale terminological and conceptual information having relationship-rich semantic resources in order to reformulate, match, and merge retrieved information of …

Religious Premises, Legislative Judgments, And The Establishment Clause, Scott C. Idleman Jan 2002

Religious Premises, Legislative Judgments, And The Establishment Clause, Scott C. Idleman

Faculty Publications

This article addresses the constitutionality under the First Amendment Establishment Clause of the legislative use of religious premises - particularly religious moral premises--in the formulation of regulatory and criminal statutes. Although much scholarly writing has been devoted to analyzing the philosophical acceptability of such legislative reliance, very little has been written specifically addressing the issue under the Establishment Clause, which is, of course, a question of great potential significance to actual or prospective litigants, to legislators and legislative drafters, and ultimately to judges. The analysis consists of three perspectives: the tests or doctrines of the Establishment Clause, the special role …
