Statistical Consulting In A Geographically Dispersed Organization, Richard M. Engeman, William E. Dusenberry

United States Department of Agriculture Wildlife Services: Staff Publications

There has been much discussion in the recent statistical literature concerning the optimal manner for a consulting statistician to operate within a larger organization. Marquardt (1979) described the "total involvement" approach, involving a statistician from conceptualization of a project to the final report; Finney (1982) discussed the questions a statistician should ask for effective consulting; and Bishop, Peterson, and Tragser (1982) argued that a statistician's most substantive contributions are made during the planning stages of a study. McCulloch et al. (1982) described a program for training statistical consultants, and Hunter (1981) discussed the roles a statistician may assume.

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson

Publications (WR)

Several limnological studies have been conducted in Lake Mead during the past decade. The recent studies clearly show that most of Lake Mead is deficient in nutrients, especially phosphorus, and very low in productivity. The reservoir-wide average total phosphorus concentration for 1981 - 1982 was only 9 mg/m³. This is below levels found In most oligotrophic lakes and reservoirs. Algal biomass, as measured by chlorophyll-a, averaged only 1.5 mg/m³. That also places Lake Mead in the oligotrophic range. Transparency, as measured by a Secchi disc, averaged 9-5 m in Lake Mead during 1981-1982. That far exceeds …

U.S. Input-Output Data: A 1984 Update, Ronald E. Miller

Accounts and Data

This paper calls attention to the U.S. national input-output data for 1977 and the U.S. multiregional input-output data for the same year; both of these data sets became available during 1984. In particular, the commodity-by- industry accounting scheme which underpins both the 1972 and 1977 U.S. national models (as well as the U.S. 1977 multiregional model), is contrasted with the industry-by-industry approach of the original Leontief framework, which was the basis of the pre-1972 U.S. national tables.

Some Comments On The Concepts Of Dose And Dose Equivalent, Robert Katz, Werner Hofmann

Robert Katz Publications

Although dose is the simplest and most widely used measurement of a radiation field, it does not always lead to an unambiguous estimate of response. This is reflected in the very wide range of relative biologic effectiveness (RBE) values for biological systems. The ambiguity arises from the focus on energy deposition as the source of biological effect, whether in macroscopic or microscopic volumes. The properties of the biological detector play a role equally important to the properties of the radiation field in their interaction. To predict even the most experimentally accessible biological response, cell killing, we must know the probability …

Expression Of Epstein-Barr Virus (Ebv) Dna And Cloned Dna Fragments In Human Lymphocytes Following Sendai Virus Envelope-Mediated Gene Transfer, David J. Volsky, Thomas Gross, Faruk Sinangil, Charles Kuszynski, Ronald Bartzatt, Timothy Dambaugh, Elliott Kieff

Chemistry Faculty Proceedings & Presentations

Purified EBV DNA and cloned DNA fragments were trapped in Sendai virus (SV) envelopes during envelope reconstitution. The DNA-loaded reconstituted envelopes (RSVE/DNA) served as gene-transfer vehicles using the capability of RSVE to fuse with normal and tumor cells. The efficiency of RSVE-mediated EBV DNA transfer into lymphoid tumor cells and fresh human lymphocytes was 5-10% of the enveloped 3H-labeled EcoRI fragment B of EBV DNA. Purified intracellular EBV (B95-8 strain) DNA induced EBV nuclear antigen (EBNA) in 0.2-1% of human lymphocytes, transiently stimulated cellular DNA synthesis, but did not fully transform cells. Cloned Sal I F1 fragment [approximately equal to …

Characterization Of Glycated Proteins By 13C Nmr Spectroscopy, Carolyn I. Neglia, Helga J. Cohen, Albert R. Garber, Suzanne R. Thorpe, John W. Baynes

Faculty Publications

13C NMR spectroscopy has been used to characterize Amadori (ketoamine) adducts formed by reaction of [2-13C]glucose with free amino groups of protein. The spectra of glycated proteins were acquired in phosphate buffer at pH 7.4 and were interpreted by reference to the spectra of model compounds, N alpha-formyl-N epsilon-fructose-lysine and glycated poly-L-lysine (GlcPLL). The anomeric carbon region of the spectrum (approximately 90-105 ppm) of glycated cytochrome c was superimposable on that of N alpha-formyl-N epsilon-fructose-lysine, and contained three peaks characteristic of the alpha- and beta-furanose and beta-pyranose anomers of Amadori adducts to peripheral lysine residues on protein (pK alpha approximately …

Success In Rat Control In Kuwait, K.S. Al-Sanei, T.M. Zaghloul, A.M. Salit, M.T. Omar, M.M. Balba

Vertebrate Pest Conference Proceedings: 11th (1984)

The preliminary rat survey prior to the actual attack phase of Rat Control Program in Kuwait revealed an infestation rate with the Norway rat, Rattus norveqicus, in buildings ranging between 32.7% and 70.7%. The comparatively high infestation was observed in 92.5% of Kuwait buildings. Moreover the infestation reached 99% in certain districts of the country. This high infestation was associated with an increase in rat-borne diseases particularly murine typhus, salmonellosis, rat-bite fever and certain parasitic diseases.

A programme for rodent control in Kuwait was initiated through a political decision by the cabinet which gave the full responsibility of rodent …

Hazards To Golden-Mantled Ground Squirrels And Associated Secondary Hazard Potential From Strychnine For Forest Secondary Pocket Gophers, R. Michael Anthony, Gerald D. Lindsey, James Evans

Vertebrate Pest Conference Proceedings: 11th (1984)

Radio telemetry and capture-recapture techniques were used to evaluate the hazards to golden-mantled ground squirrels ( Spermophilus lateralis) from hand baiting with 0.5% strychnine-treated for western pocket gophers (Thomomys mazama) on conifer plantations in eastern Oregon. Toxicology data were collected on field-killed and caged ground squirrels and on caged mink (Mustela vison, great horned owls (Bubo virginianus), and red-tailed hawks (Buteo jamaicensis). Ground squirrel populations were reduced 50% to 75% following underground baiting for pocket gophers. Maximum amount of strychnine found in cheek pouches and carcass of a field-killed golden-mantled ground …

Commingling Of Norway And Roof Rats With Native Rodents, Rex O. Baker

Vertebrate Pest Conference Proceedings: 11th (1984)

The ecology of plague relies on the intermixing (commingling) of animal hosts and their ectoparasites. There has been a noticeable increase in commingling of rats and ground squirrels in Southern California in recent years. This paper discusses this phenomenon in Los Angeles and Orange Counties, where it occurs, how it results from man's activities, and the ecology of varying locations. The role of fleas as vectors of plague and the intermixing of fleas between hosts are discussed. Action to reduce the incidence of commingling and the threat of plague to the urban society is addressed.

Efficacy Of Three Anticoagulant Rodenticides For The Control Of Poison-Shy Rattus Rattus, Devendra Bhardwaj, Ishwar Prakash

Vertebrate Pest Conference Proceedings: 11th (1984)

House rats (Rattus rattus) which do not consume a lethal dose of zinc phosphide develop poison-shyness after a single exposure. The surviving poison-shy rats cannot be baited again with zinc phosphide for about three months. Poison-shy rats were separately given anticoagulant baits (brodifa-coum 0.005%, coumatetralyl and warfarin 0.025%) in no-choice tests. The first two anticoagulants were found to be the most efficient ones. It was observed that those R. rattus which had consumed 56.7 mg/kg or more zinc phosphide died sooner (P < 0.05 to 0.1) after anticoagulant poisoning when compared with normal rats. It is conjectured that prothrombin inhibition is accelerated in the liver of poison-shy R. rattus due to the action of phosphine present in the earlier ingested sublethal dose of …

Preliminary Investigations Of The Effectiveness Of Trimethacarb As A Bird Repellent In Developing Countries, R.L. Bruggers, P. Sultana, J.E. Brooks, L.A. Fiedler, M. Rimpel, S. Manikowski, N. Shivanarayan, N. Santhaiah, I. Okuno

Vertebrate Pest Conference Proceedings: 11th (1984)

Preliminary information on the effectiveness of trimethacarb as a bird repellent on broadcast seed and ripening crops was obtained during 1982 and 1983 from studies in Haiti, India, the Philippines, Bangladesh, Mali, and the United States. R50 and LD50 determinations for nine pest bird species to cereal crops in these countries indicated birds were not as sensitive to trimethacarb as to the avian repellent methiocarb. Rice and millet seed germination was not inhibited at 0.125 and 0.25% treatment levels. Wheat seed germinated well at treatments of ≤0.5% in Bangladesh. Sorghum seed did not germinate as well at any treatment level. …

Repellent Or Aversive Chemicals In Sheep Neck Collars Did Not Deter Coyote Attacks, Richard J. Burns, Guy E. Connolly, Richard E. Griffiths Jr.

Vertebrate Pest Conference Proceedings: 11th (1984)

Since 1974 the Fish and Wildlife Service has studied a "toxic collar" to poison coyotes that attack collared sheep and goats. The collar patent (McBride 1974) indicates that the same collar could deliver chemicals to repel coyotes, thus saving both the coyote and the livestock.

This report summarizes our experience with nonlethal tests of collars. During collar tests with 10 different toxicants, 21 coyotes received sublethal doses followed by aversive behavior or potentially aversive reactions. The subsequent predation history of these coyotes was examined for prey-avoidance. After a sublethal test, all coyotes killed lambs or kids in about 40 days, …

Vole Control In Field Crops, Jerry P. Clark

Vertebrate Pest Conference Proceedings: 11th (1984)

There are five species of meadow voles found in California. The two that are most economically important are Microtus californicus and Microtus montanus. Meadow vole populations are extremely cyclic, reaching a peak every four to six years. During these periods when the vole population is increasing in numbers, damage to crops like alfalfa, artichokes, potatoes, and sugar beets can occur. The best time to survey for vole activity is before the crop is planted. The grower or farm operator should look for vole activity in grassy borders around the crop or along roadsides and ditch bank areas. Snap-trapping may …

Performance Of Sodium Cyanide Ejectors, Guy Connnolly, Gary D. Simmons

Vertebrate Pest Conference Proceedings: 11th (1984)

Performance of three models of sodium cyanide (NaCN) ejectors was evaluated at Port O'Connor, Texas, early in 1982. M-44s, M-50s, and coyote getters were test-pulled and reset at 7-day or 21-day intervals for 42 days. Each pull was recorded as good if, in our judgment, it would have taken a coyote. Based on 402 to 430 test pulls of each ejector model, the percentages of good pulls were 40% for M-50s, 73% for M-44s, and 99% for coyote getters. M-44s with shortened plungers performed better than standard M-44s.

Most pulls of M-50s resulted in ejection failure due to corrosion between …

Nuisance Bats: Current Technology In Their Management And Control, Robert L. Corrigan

Vertebrate Pest Conference Proceedings: 11th (1984)

Managing nuisance bat colonies can be accomplished via exclusion (bat-proofing) or in limited cases via the use of repellents. Exclusion is emphasized as the first and most desirable approach providing it is also practical. New products and devices have recently become available which may significantly aid in making exclusion programs more possible and practical. Repellents such as lights, fiberglass batting and various improvised mechanical devices may all have some utilization. Controlling nuisance bats can be accomplished via the use of toxicants and trapping, although there is considerable opposition from many bat researchers towards the use of toxicants. Toxicants that have …

Woodpeckers: A Serious Suburban Problem?, Scott R. Craven

Vertebrate Pest Conference Proceedings: 11th (1984)

Damage to homes and buildings caused by woodpeckers is a widespread and locally severe problem in vertebrate pest control. This paper describes the distribution, characteristics, and impacts of woodpecker damage as determined by questionnaires, interviews, and published accounts. Woodpecker damage results from territorial behavior, feeding, or nesting activity. Some plywood and cedar are especially vulnerable. Average loss per incident is about $300, although some cases result in much greater losses. Disturbance and aggravation are also important factors. Abatement measures include scare devices, structural modification, chemical treatment of the siding, and shooting or trapping (with a permit). Success is variable. Recommendations …

Keynote Address—Politics Of Pesticides, David H. Dietz

Vertebrate Pest Conference Proceedings: 11th (1984)

The politics of pesticides is a rather humorless topic, as I'm sure most of you know. I've always been told that when you start an address or make a speech you ought to have some kind of humor, if for no other reason that you at least get your audience to listen to you for two minutes during any presen-tation. For those of you that may be members of the Audubon Society or members of the Sierra Club, I'll, in advance, make my apologies for the joke I'm about to tell. It's not really meant as a put down if …

Rat Control In Alberta, Michael J. Dorrance

Vertebrate Pest Conference Proceedings: 11th (1984)

A rat control program, administered and coordinated by Alberta Department of Agriculture, has kept Alberta essentially free of Norway rats (Rattus norvegicus) since 1950. A control zone, 29 x 600 km, along the eastern border prevents rats from moving into Alberta from the east. Sporadic rat infestations within the interior of Alberta are reported by concerned citizens and eradicated by government personnel. Strong support for the program by citizens and local governments was developed through public education and information. The program has been successful for a variety of reasons including geography, climate, legislation, availability of warfarin, the relatively …

Opening Remarks—Eleventh Vertebrate Pest Conference, Dell O'Clark

Vertebrate Pest Conference Proceedings: 11th (1984)

On behalf of the Vertebrate Pest Council, it is my pleasure to welcome all of you to Sacramento and to the 11th Vertebrate Pest Conference. The first Vertebrate Pest Conference was held 22 years ago here in Sacramento in 1962. The conference is now over two years into its third decade of existence. In all this time, the basic goals of the Conference have not changed; that is, to provide a basis for dissemination of information on vertebrate pests and their control. Some things have changed in these 22 years, most of which have been for the good. The first …

Groundwater Quality And Mineral Deposits Relationships In The Ozark Mountains, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Ninety-nine groundwater sites were sampled in northern Arkansas in order to determine the effect of local manganese, phosphate, pyrite, lead-zinc and uranium mineralization on the groundwater chemistry. Most of this study (75 springs) was concentrated in the Batesville manganese district. Hydrogeochemical exploration for these types of manganese deposits appears possible with 44 percent of the springs within 2000 feet of mineralization having anomalous metal concentrations (especially manganese). Because only a few springs were sampled in the remaining areas, the results are not conclusive; however, only the pyrite and small lead-zinc deposit would appear worthy of additional investigation. None of the …

Wetlands And Coal Surface Mining: A Management Handbook, Milady A. Cardamone, Jan R. Taylor, William J. Mitsch

KWRRI Research Reports

As the third phase of a three-year project, this report outlines management options for protecting wetlands during the surface mining of coal, particularly for the portion of the Eastern Interior Coal Region that is found in Kentucky, Indiana, and Illinois. It is presented in manual form for use by coal mine operators, regulatory agencies and research institutions.

The previous phases of the project produced an atlas of the most heavily-mined areas of the western Kentucky coal field, which classified and identified wetlands in these areas, and discussed some specific impacts of mining on these wetlands. The need to present information …

Finite Element Simulation Of Saturated-Unsaturated Subsurface Flow, George E. Blandford

KWRRI Research Reports

A two-dimensional transient model for flow through saturated-unsaturated porous media is developed, The model numerically solves the pressure head dependent or moisture content dependent form of Richard's equation. The model code uses isoparametric quadratic triangular and/or quadrilateral finite elements for the geometric representation and for the weak Galerkin spacial integrations. An implicit, unconditionally stable single-step numerical time integration scheme with an oscilliatory noise reduction option is utilized for the temporal discretization. The highly efficient symmetric skyline (profile) solution scheme is used to solve the resulting simultaneous equations. The nonlinear subsurface flow parameters are approximated using cubic spline interpolation. The element …

Discharge And Travel Time Determinations In The Royal Spring Groundwater Basin, Kentucky, John Thrailkill, Douglas R. Gouzie

KWRRI Research Reports

Groundwater flow in many karst regions, including the Inner Bluegrass Karst Region of central Kentucky in which the study area was located, is unlike groundwater flow in granular aquifers. At least the major flows are turbulent and often with a free surface in large conduits, and applying concepts based on Darcy's Law to describe and model these flows is inappropriate. Parameters such as linear velocity, channel geometry, and conveyance used to describe surface streamflows are more applicable, and the primary objective of the project was to estimate these in a groundwater basin using the travel time of dye slugs and …

Toxicological Studies On Aquatic Contaminants Originating From Coal Production And Utilization: The Induction Of Tolerance To Silver In Laboratory Populations Of Fish And The Chronic Toxicity Of Nickel To Fish Early Life Stages, Wesley J. Birge, Jeffrey A. Black, James F. Hobson, Albert G. Westerman

KWRRI Research Reports

Aquatic toxicity studies were performed on two important coal-derived contaminants, silver and nickel. Silver was investigated with regard to metal-induced tolerance in laboratory populations of the fathead minnow (Pimephales promelas). Fish were exposed to acute silver concentrations following acclimation to sublethal exposures of this metal. Based on median lethal times (LT50), animals which had received 14 days prior exposure to 1.5 and 15 μg Ag/L were three to four times more resistant to silver than were previously unexposed organisms. This metal-induced resistance was not a sustained response. After organisms which had been acclimated to 15 μg/L had been transferred to …
