Morphometric Analysis Of Anguina Amsinckiae From Three Host Species, Dan James Pantone, John A. Griesbach, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Amsinckia species (fiddleneck) in the South Coast Ranges of California were surveyed to determine if any of the 12 different California species of Amsinckia are hosts of the nematode, Anguina amsinckiae (Steiner and Scott, 1935) Thorne, 1961. Previously only Amsinckia intermedia Fischer and Meyer was reported as a host of Anguina amsinckiae. The survey established that there are at least two additional hosts of Anguina amsinckiae: Amsinckia lycopsoides Lehmann and Amsinckia gloriosa Suksdorf. Seven sites containing nematode-infected Amsinckia plants were discovered. Every site contained two or more species of Amsinckia; however, only one site contained more than …

[Minimizing The Trauma Of Judicial Ethical And Disciplinary Problems], Edward F. Hennessey

Nebraska Law Review

All speakers today have emphasized the necessity of doing everything valid that we can do to sustain public confidence in the judiciary. First and foremost, we have recognized the need for mandatory and early education of judges as to the code of judicial conduct, and as to ethical considerations for judges. Second, we have found that bench and bar committees in dialogue with judges have been helpful. Third, chief judges must be willing to act to keep foreseeable situations from escalating into disciplinary proceedings. Fourth, openness and the appearance of openness are a necessity for the investigating and disciplinary process. …

Physically Disabled Women And New Directions In Public Policy, 1977-1987., Mary Jo Deegan

Department of Sociology: Faculty Publications

Women with physical disabilities now demand new directions in public policy. Starting a mere decade ago, in 1977, a driving momentum redefined the self-concepts, expectations, and united actions of disabled women. This burgeoning social movement is documented here through the geometric growth of writings articulating the vision of a more active and independent group. An overview of this Iiterature and its policy implications is provided.

A Cross-Cultural Analysis Of Several Forms Of Parenting: Mother, Genitrix, And Mater, Michael R. Hill

Department of Sociology: Faculty Publications

Melissa Stern was born March 27, 1986, in New Jersey. For one so young, she has experienced or been the subject of interstate flight and fugitive hegira, legal battles involving her own court-appointed attorney, social controversy, the voracious attention of an insensitive media industry, and a place in history as the famous Baby "M". Judge Sorkow (1987: 26-27), in his opinion awarding custody of Melissa to her genetic father and terminating all parental rights of her genetic mother, notes professional evaluations indicating Melissa to be a "a mellow, alert, easy-to-care-for child who is blessed with a 'sunniness of disposition that …

Leaders And Non-Leaders, Paul Brooks, Will Norton Jr., John W. Windhauser

College of Journalism and Mass Communications: Faculty Publications

Newspaper editors often think of community leaders as being different from other newspaper readers. Such an assumption is supported with studies showing that opinion ' leaders have greater exposure to mass media than their followers and read different types of articles than do non-leaders.

But a recent study in Oxford, Miss., shows that media use patterns by leaders and non-leaders in a small rural community do not differ as much as previous studies seem to indicate. Perhaps the main reason that former studies reported vast differences in these two groups was the selection of opinion leaders. Earlier studies were skewed …

Stings Of Ants Of The Tribe Pheidologetini (Myrmicinae), Charles Kugler

Insecta Mundi

The definition of the Tribe Pheidologetini in the ant subfamily Myrmicinae has always been problematic. Emery (1922) erected the tribe to contain the genera Pheidologeton, Oligomyrmex, Aneleus, Lophomyrmex, Trigonogaster, Ekebomyrma, Carebara and Paedalgus, but Wheeler (1922) put all these genera in the Solenopsidini. Neither Emery nor Wheeler satisfactorily defined either tribe. More recently, Ettershank (1966) proposed the “Pheidologeton genus group” composed of Pheidologeton, Oligomyrmex (including most Aneleus) , Lophomyrmex, Carebara, Paedalgus and Anisopheidole, but still uncertainty remains as to relationships of these genera and even the definitions of the genera themselves. New characters and new means of analysis are needed …

A Study Of The Factors Which Influenced The Perception Of Cooperation Between County Extension Agents And Vocational Agriculture Teachers In Nebraska, Robert Duwaine Boettcher

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

The primary purpose of this study was to determine the factors which county agents and vocational agriculture teachers perceived to influence the extent of cooperative arrangements and activities that exist in Nebraska. A questionnaire was used to survey county extension agents and vocational agriculture teachers in Nebraska. The sample was drawn from all agents and teachers in Nebraska in April 1986. A 50 percent sample of each population was selected to receive surveys with 34 of the 45 county agents and 61 of the 70 vocational agriculture teachers providing valid responses. The results were tested for frequency and then cross …

The Radial Distribution Of Dose Around The Path Of A Heavy Ion In Liquid Water, M. P. R. Waligorski, R. N. Hamm, Robert Katz

Robert Katz Publications

Monte Carlo calculations of the radial distribution of dose in liquid water, incorporating energy deposition due to primary excitations and ionizations, have been performed for protons of energy 1, 10, 20, 50, and 100 MeV. By combining these results with earlier semi-empirical formulae used in track structure theory calculations, a corrected analytic formulation has been developed which on radial integration closely reproduces the value of stopping power for protons in the energy range 0.1–1000 MeV. After including a β-dependent ‘effective charge’ formula, this corrected formulation is tested against all published measurements of radial distribution of dose from energetic ions in …

Revision Of The Nearctic Glyphicnemis Foerster (Hymenoptera: Ichneumonidae, Gelinae), John Luhman

Insecta Mundi

GLYPHICNEMIS Foerster is a small Holarctic genus in the subtribe Endaseina of the Gelini. Nearctic species were placed in PHYGADEUON Gravenhorst until Townes (1944) placed them in the subgenus GLYPHICNEMIS within ENDASYS Foerster . However, earlier Cushman (1925) had transferred PHYGADEUON CRASSIPES Provancher, a junior synonym of G. MANDIBULARIS (Cresson), to GLYPHICNEMIS, and the Palearctic species, at first placed in PHYGADEUON, were included by Habermehl (1916) i n GLYPHICNEMIS, reduced t o a subgenus within STYLOCRYPTUS Thomson (1873). This status was continued until Townes (1970) listed and described GLYPHICNEMIS as a seperate genus.

Contribucion Al Conocimiento De Los Pepsinae Sudamericanos (Hymenoptera, Pompilidae) Iii. El Genero Priocnemis Schiødte En Chile, Arturo Roig Alsina

Insecta Mundi

El género Priocnemis SchiØdte no se puede considerar como caracteristico de la Región Neotropical y son pocas las especies descritas que se conocen de ella. Sin embargo en el área extra-tropical sudamericana se halla bastante bien representado por un grupo de especies que presenta características particulares, como veremos más adelante. Son varias las especies presentes en la Argentina, Uruguay y Chile, pero por el momento vamos a referirnosala fauna de este último país. Debemos aclarar que no consideramos aquí las especies correspondientes a Sphictostethus Kohl, que han sido tratadas como Priocnemis por algunos autores, ya que constituye un género bien …

Praestochrysis Of The Ethiopian Region With A Key And Descriptions Of New Species(Hymenoptera: Chrysididae), R. M. Bohart

Insecta Mundi

Praestochrysis Linsenmaier contains those species of Chrysidinae with five teeth on the posterior margin of tergum III, first flagellomere (F-I) less than 3 times as long as broad (often much shorter), and clypeal length below antennal sockets (subantennal distance) not more than diameter of the midocellus (MOD). The genus is widespread in the Old World, but a majority of the known species are in the Ethiopian Region. Host records are rather few, but it is likely that nearly all species attack moth larvae and emerge from their cocoons. Praestochrysis shanghaiensis (F. Smith) is a well known parasitoid of the silk …

The Systematics And Biology Of The Flea Beetle Genus Crepidodera Chevrolat (Coleoptera: Chrysomelidae) In America North Of Mexico, Richard H. Parry

Insecta Mundi

Crepidodera Chevrolat is a genus of small metallic-colored flea beetles belonging to the family Chrysomelidae. Although these insects are quite common in the field and numerous in museum collections, the members of the genus in North America are, until now, poorly known. Heikertinger (1948-1950) recognized 4 taxa and recently, Lazorko (1974) described 3 additional species. These 7 species were recognized primarily on the basis of genital differences and were otherwise difficult to identify.

Examination of a large accumulation of museum material and investigations in the field have indicated the presence of several additional species in the North American fauna. A …

Analysis Of Mosquito Larvicidal Potential Exhibited By Vegetative Cells Of Bacillus Thuringiensis Subsp. Israelensis, Corey J. Walther, Graham A. Couche, Mary Ann Pfannenstiel, Sara E. Egan, Lisa A. Bivin, Kenneth W. Nickerson

Papers in Microbiology

Vegetative Bacillus thuringiensis subsp. israelensis cells (6 x 10⁵/ml) achieved 100% mortality of Aedes aegypti larvae within 24 h. This larvicidal potential was localized within the cells; the cell-free supernatants did not kill mosquito larvae. However, they did contain a heat-labile hemolysin which was immunologically distinct from the general cytolytic (hemolytic) factor released during solubilization of B. thuringiensis subsp. israelensis crystals. The larvicidal potential of the vegetative cells was not due to poly-3-hydroxybutyrate. Instead, it correlated with the ability of vegetative cells to sporulate during the bioassays. No toxicity was observed when bioassays were conducted in the presence …

Differential Effects Of Lithium Chloride On In Vitro Growth Of Clavibacter Michiganense Subsp. Nebraskense Depending Upon Inoculum Source, Mary L. Smidt, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

The bacterium Clavibacter michiganense subsp. nebraskense (Corynebacterium michiganense subsp. nebraskense) was grown in broth cultures and inoculated into corn plants. The plating efficiency of cells from broth cultures was essentially the same on nutrient broth-yeast extract and the semiselective medium for this bacterium, CNS. However, when cells were isolated from Goss bacterial wilt- and blight-infected corn, very few were recovered on CNS compared with the amount recovered on nutrient broth-yeast extract agar. When lithium chloride was omitted from the CNS, recoveries from infected corn were nearly the same as on nutrient broth-yeast extract agar. No other ingredient of CNS …

Natural And Experimental Infection With An Attaching And Effacing Strain Of Escherichia Coli In Calvest, Rodney A. Moxley, David H. Francis

School of Veterinary and Biomedical Sciences: Faculty Publications

Gnotobiotic calves were inoculated with an 05:K4:H^-, urease-positive strain of Escherichia coli isolated from a 2-day-old calf with diarrhea. The calves developed elevated temperatures and passed loose mucoid feces, with or without blood. The E. coli strain was negative for heat-stable and heat-labile enterotoxins but produced high levels of Shiga-like toxin. Bacteria attached diffusely to the epithelium of the large intestine and multifocally to the epithelium of the ileum. The duodenum and jejunum were not affected. At the sites of bacterial attachment, microvilli were effaced, enterocytes were degenerate, and necrosis and exfoliation had occurred. These results confirm a …

Economies Of Scale And The New Technology Of Daily Newspapers: A Survivor Analysis, Seth W. Norton, Will Norton Jr.

College of Journalism and Mass Communications: Faculty Publications

The economics of the newspaper industry occupies a special place in industrial organization. Unlike the vast majority of enterprises, this business is intimately linked to the protection of freedom of expression. Constitutional democracies generally have monitored it with special care. In the United States the Newspaper Preservation Act of 1970 provides some antitrust immunity for segments of the industry. Ignoring a captive regulation (pro-producer, wealth-maximizing) rationale for the act, we may presume that the United States Congress deems daily newspaper viability as an objective superior to the conventional reasons for antitrust. The received logic rests on the notion that newspapers …

The Multidimensionality Of Joining, Suzanne T. Ortega, J. Allen Williams Jr.

Department of Sociology: Faculty Publications

By focusing on membership in voluntary associations in general, the question of whether correlates of affiliation vary by organizational type tends to have been neglected. This is a significant omission from the standpoint of describing the characteristics of “joiners.” Additionally, most of what we know about the reasons for belonging has been inferred from observations of who joins. In this study, nine frequently identified correlates of voluntary association membership were examined in relation to five different types of organizations. Only two, education and race, were found to be related to all types. Thus, results indicate that affiliation is not a …

Implications And Management Of Feral Mammals In California, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 12th (1986)

"Feral" is defined. For each of the principal species of feral mammals in California we note the broad ecological implications they have on the environment and the potential or actual management approaches being followed. The main emphasis of this paper, and all of the slides shown, was on how wild horses and burros, two controversial feral species, are managed in California and in other western states. The feral pig is about to become the number one big game animal in California, and mustrats (Ondatra zibethica (L.)), which were introduced or escaped into the Sacramento Valley—-hence locally feral--are the state's …

An Integrated Approach To Bubonic Plague Control In A Southwestern Plague Focus, Curtis E. Montman, Allan M. Barnes, Gary O. Maupin

Vertebrate Pest Conference Proceedings: 12th (1986)

Plague is widespread among rodents and their fleas in the western United States, but most human cases occur in several definable, ecologically unique, and geographically limited high risk areas in the Southwest and Pacific Coast states. Control strategies to prevent human cases in high risk areas must vary from one epizootic focus to another, depending on such basic ecological factors as rodent/flea species involved; their distribution, abundance, seasonality, and relationship with the plague organism; climatic factors that affect transmission; the lifestyles of human residents; and others. This paper briefly summarizes preliminary results of a long-term program to define human risk …

The Complexities At The Interface Among Domestic/Wild Rodents, Fleas, Pets, And Man In Urban Plague Ecology In Los Angeles, County, California, Bernard C. Nelson, Minoo B. Madon, Arthur Tilzer

Vertebrate Pest Conference Proceedings: 12th (1986)

Bubonic plague was first found in Los Angeles County in 1908. The largest epidemic of pneumonic plague in the United States occurred in the county in 1924, and the last cases of plague associated with domestic rodents in the United States occurred here in 1925. Sporadic plague activity was recorded from 1925 to 1975. Since 1975, plague has been found annually and is now endemic in the San Gabriel Mountains and the interface, that area where suburban encroachment intermingles with wilderness areas along the southern edge of these mountains. Within these two areas, plague is amplified and is a risk …

Genetic Engineering Of Livestock Improvement, Gordon E. Dickerson

World Congress on Genetics Applied to Livestock Production: 3rd (1986)

Genetic engineering requires clearly defined objectives, adequate genetic variability and effective methods of selection. In a given production-marketing System, relative importance of genetic change in alternative traits can be estimated from expected effects on cost per unit of output, using available biological and economic information. Diversity among existing breeds and their crosses is a primary and quickly usable genetic resource, and its management for future needs is a public concern. Better physiological and biochemical understanding of the genetic controls of animal development and function is important to permit more effective selection for efficiency of animal production under diverse environments. Long-term …
