Two Comparisons Of Rural Public Television Viewers And Nonviewers In, Will Norton Jr., John W. Windhauser, Susan Langdon Norton Sep 1992

Two Comparisons Of Rural Public Television Viewers And Nonviewers In, Will Norton Jr., John W. Windhauser, Susan Langdon Norton

College of Journalism and Mass Communications: Faculty Publications

A study of public television viewers in Oxford, Mississippi, in 1977 and 1989 found both consistency and differences in viewing patterns. In both periods, viewers watched television in general about six hours a day. But viewers of all education levels were much more likely to watch public television in 1989 than in 1977, when watchers tended to be those with higher levels of education. The amount of time spent watching public television inched up in 1989, and there is evidence that viewers assimilated public television more into their regular viewing. The study concludes that public television appeals to a broader …

Solutions Of The Heat Conduction Equation In Multilayers For Photothermal Deflection Experiments, William A. Mcgahan, Kevin D. Cole Aug 1992

Solutions Of The Heat Conduction Equation In Multilayers For Photothermal Deflection Experiments, William A. Mcgahan, Kevin D. Cole

Department of Mechanical and Materials Engineering: Faculty Publications

Exact expressions are presented for the deflection of a laser beam passing parallel to and above the surface of a sample heated by a periodically modulated axisymmetric laser beam. The sample may consist of any number of planar films on a thick substrate. These exact expressions are derived from a local Green’s function treatment of the heat conduction equation, and contain an exact analytical treatment of the absorption of energy in the multilayered system from the heating laser. The method is based on calculation of the normal component of the heat fluxes across the layer boundaries, from which either the …


Lipoxygenase Inhibitors Shift The Yeast/Mycelium Dimorphism In Ceratocystis Ulmi, Ellen C. Jensen, Clyde Ogg, Kenneth W. Nickerson Aug 1992

Lipoxygenase Inhibitors Shift The Yeast/Mycelium Dimorphism In Ceratocystis Ulmi, Ellen C. Jensen, Clyde Ogg, Kenneth W. Nickerson

Papers in Microbiology

The yeast-mycelium dimorphism in Ceratocystis ulmi, the causative agent of Dutch elm disease, was switched by gossypol, nordihydroguaiaretic acid, and propylgallate. In each case the mycelial form was converted to the yeast form. These compounds are recognized lipoxygenase inhibitors. Inhibitors of cyclooxygenase and thromboxane synthetase did not cause mycelia to shift to the yeast form. We suggest the following two-part hypothesis: (i) that lipoxygenase is a target for antifungal antibiotics and (ii) that many phytoalexins (antimicrobial compounds of plant origin) are targeted toward fungal lipoxygenases. In addition, in a study to determine potential lipoxygenase substrates, a fatty acid analysis …

Papers in Biotechnology

The effect of pronuclear microinjection of DNA and culture in excised mouse oviducts on the development of porcine zygotes was assessed in this study. Precocious ovulation was induced in prepubertal gilts with pregnant mare's serum gonadotrophin and hCG. Zygotes received either pronuclear microinjection of buffer alone, buffer containing a DNA construct, or no microinjection. Zygotes were cultured in vitro in either modified Krebs-Ringer bicarbonate medium (KRBI for 144 h or in mouse oviduct (MO) explant culture with KRB for 48, 72, 96, or 120 h. Pronuclear microinjection of DNA resulted in a lower (P < .05) cleavage index (CII than did buffer or no microinjection (CI 2.16 k .10 vs 2.80 f .13 and 2.93 f .lo). The CI loss was greatest for DNA-injected zygotes at the two-cell stage of development. Coculture of zygotes in MO resulted in a higher CI (P < .01) than did culture in KRB. Culture in MO for 72 h was the most beneficial system compared with MO for 48, 96, or 120 h (P < .05; CI 3.25 k .12 vs 2.66 k .18, 2.79 f .14, and 2.40 .14, respectively). Microinjection of DNA, not merely the mechanical procedure, was detrimental to early zygote development and may be the cause of low pregnancy rates.

Groundwater Flow In A Compressible Unconfined Aquifer With Uniform Circular Recharge, Vitaly A. Zlotnik, Glenn Ledder Jun 1992

Groundwater Flow In A Compressible Unconfined Aquifer With Uniform Circular Recharge, Vitaly A. Zlotnik, Glenn Ledder

Department of Earth and Atmospheric Sciences: Faculty Publications

The distributions of the hydraulic head and velocity components of the transient groundwater flow in an unconfined compressible aquifer of finite thickness under constant uniform circular recharge are obtained from the linearized mathematical model by the use of integral transforms. The result generalizes Dagan’s (1967) solution which was derived by neglecting the compressibility. By treating the compressibility parameter as a small value, the formula for the hydraulic head is analyzed by asymptotic methods, resulting in approximations to the exact solutions for the head and velocities on small and large time scales. The hydraulic head and flow velocities can be accurately …

Biological Collections At The University Of California, Davis: Scope, Status, And Needs, Scott Lyell Gardner, Lynn S. Kimsey, Marilyn S. Warburton, Patrick E. Mcguire

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The rich heritage of agricultural and biological research and teaching on the Davis campus of the University of California is reflected in its vast holdings of scientific collections of living and nonliving preserved biological materials. More recently, as the campus expanded, important collections were developed to support research and educational programs in human and veterinary medicine, anthropology, and geology. A task force reviewed the results of campus-wide surveys and its findings are reported here. Recommendations for future activities are put forth.

Using The Project Approach With Toddlers, Debbie Leekeenan, Carolyn P. Edwards May 1992

Using The Project Approach With Toddlers, Debbie Leekeenan, Carolyn P. Edwards

Department of Child, Youth, and Family Studies: Faculty Publications

“From the very beginning, curiosity and learning refuse simple and isolated things: they love to find the dimensions and relations of complex situations....” (Malaguzzi, 1987, p.19)

While working with children at a university laboratory school, we have pondered the question of how to develop curriculum for very young children in a meaningful way that emphasizes content as well as process. In general, curriculum for toddlers (ages one through three) involves activity centers that change from day to day. Because toddlers tend to be immersed in the immediate moment and in the process rather than the product of their activity, teachers, …


Deterrents To Female Enrollment In Secondary Agricultural Education Programs In Nebraska, Lloyd C. Bell, Susan Fritz Apr 1992

Deterrents To Female Enrollment In Secondary Agricultural Education Programs In Nebraska, Lloyd C. Bell, Susan Fritz

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

“Scientific and professional expertise in the food and agricultural sciences is a national resource critical to the continuing security of this Nation.” This renewable resource, however, is being depleted by an annual employment shortfall of ten percent. Approximately 4000 employment opportunities go unfilled because of too few new college graduates with expertise in agriculture, natural resources, veterinary medicine, and closely aligned fields (Coulter, 1986).

Students usually equate a career in agriculture with farming or ranching only, rather than with the science or business of agriculture which leads to a pervasively negative opinion of pursuing a career in agriculture (Orthel, Sorensen, …

Responses Of The Adc Program To A Changing American Society, Bobby R. Acord Mar 1992

Responses Of The Adc Program To A Changing American Society, Bobby R. Acord

Vertebrate Pest Conference Proceedings: 15th (1992)

Changes in the Animal Damage Control (ADC) program are reviewed relative to changes in American societal background and attitudes. Many of the program changes that occurred in the past were imposed on ADC in response to external factors, while more recent program changes have been and will continue to be more self-directed. Examples of ADC's proactive approach to dealing with critical issues are provided.


Administrative Procedures And Contracts For Vertebrate Pest Programs, Bruce A. Colvin, Curtis A. Meininger, Michael J. Grealy Mar 1992

Administrative Procedures And Contracts For Vertebrate Pest Programs, Bruce A. Colvin, Curtis A. Meininger, Michael J. Grealy

Vertebrate Pest Conference Proceedings: 15th (1992)

A proactive (rather than reactive) approach to rodent control includes effective planning, administration, and coordination. Centralized coordination, detailed scheduling, and well-defined contract specifications provide a solid basis for managing an integrated pest management program. Documentation and data management help to ensure cost effective and efficient operations. The ability to work with people and bureaucracies is essential for the science of rodent control to be applied effectively in real world situations and for vertebrate pest programs to succeed.


An Integrated Approach To The Management Of Urban Canada Goose Depredations, Steven D. Fairaizl Mar 1992

An Integrated Approach To The Management Of Urban Canada Goose Depredations, Steven D. Fairaizl

Vertebrate Pest Conference Proceedings: 15th (1992)

Canada geese (Branta canadensis) in the Reno-Sparks, Nevada urban area have become a problem of increasing significance. Nuisance complaints from city parks, golf courses, and housing developments augment the bird hazard to aircraft operations at the local airport. Eleven goose collisions with commercial aircraft, between January 1986 and April 1989, caused $250,000 in structural damages but no injuries or loss of human life. The Federal Aviation Administration required action be taken to reduce the hazard if airport certification was to continue. A multi-agency task force was formed to develop and implement an integrated pest management plan. Population surveys …


Urban Crow Roosts In California, W. Paul Gorenzel, Terrell P. Salmon Mar 1992

Urban Crow Roosts In California, W. Paul Gorenzel, Terrell P. Salmon

Vertebrate Pest Conference Proceedings: 15th (1992)

We reviewed the historical and current status of the American crow (Corvus brachyrhynchos), urban crow roosts and control efforts in California. Crows aggregate in traditional winter roosting areas. In the late 1930s most crows in California roosted in the Sacramento Valley in rural locations. Crow roosts were not a concern except for potential damage to adjacent farmlands. From the 1960s through 1980s crows colonized urban areas for nesting and winter roosting. A phone survey of vertebrate pest management officials indicated all known roosts were in urban areas, with most occurring in the Sacramento Valley. From 1970 to 1989 …

A Cage Trap For Live-Trapping Mountain Lions, James D. Shuler Mar 1992

A Cage Trap For Live-Trapping Mountain Lions, James D. Shuler

Vertebrate Pest Conference Proceedings: 15th (1992)

The use of cage traps to capture mountain lions (Felix concolor) has the potential to become a valuable tool in the USDA-APHIS-ADC program. Because of California public sentiment, many of the traditional methods can no longer be used or are being severely restricted. Due to increasing requests for assistance, California ADC personnel have had to develop a method that will be highly selective, humane, and effective in rural and urban areas. The development of the mountain lion cage trap and it’s applications are described.


Estimation Of Relative Pesticide Leaching In Nebraska Soils, P. J. Shea, L. N. Mielke, W. D. Nettleton Mar 1992

Estimation Of Relative Pesticide Leaching In Nebraska Soils, P. J. Shea, L. N. Mielke, W. D. Nettleton

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A computational procedure (RIPS, Relative Index for Pesticides and Soils) was developed as a conservative estimator of pesticide leaching and groundwater contamination based on soil and pesticide properties, and water table depth. RIPS values offer guidance in pesticide selection and identify situations where a detailed site-specific evaluation should be conducted.

Lek Formation In Sage Grouse: The Effect Of Female Choice On Male Territory Settlement, Robert M. Gibson Mar 1992

Lek Formation In Sage Grouse: The Effect Of Female Choice On Male Territory Settlement, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Previous studies of female choice in sage grouse, Centrocercus urophasianus, have identified two processes that could drive the local clustering of male territories at leks: (1) fidelity of females to previous mating sites (“temporal spillover” hypothesis), and (2) “spatial spillover” of matings from an attractive male to his immediate neighbors (“hotshot” hypothesis). The effects of each process on male territory settlement were investigated using observations of the resettlement of vacant territories and of individual site fidelity during a 7-year field study. The frequency with which vacant territories were resettled both within and between seasons increased with mating success of …
