Susceptibility Of The Legume Flower Thrips To Metarhizium Anisopliae On Different Varieties Of Cowpea, S. Ekesi, N. K. Maniania, W. Lwande Jan 2000

Susceptibility Of The Legume Flower Thrips To Metarhizium Anisopliae On Different Varieties Of Cowpea, S. Ekesi, N. K. Maniania, W. Lwande

All Peer-Reviewed Publications

The susceptibility of Megalurothrips sjostedti to Metarhizium anisopliae when reared on susceptible, tolerant, and moderately resistant varieties of cowpea at different constant temperatures was evaluated in the laboratory. Insects were exposed either to direct spray of the conidia or to fungus-treated floral tissues. Mortality was significantly higher on the moderately resistant variety at all temperatures compared to the susceptible and tolerant varieties. Correspondingly, lethal time and lethal concentration values were significantly shorter and lower, respectively, on the moderately resistant variety compared to the other varieties, thus indicating that the two control methods are compatible as part of an integrated pest …


The Uses Of History In Struggles For Racial Justice: Colonizing The Past And Managing Memory, Katherine M. Franke Jan 2000

The Uses Of History In Struggles For Racial Justice: Colonizing The Past And Managing Memory, Katherine M. Franke

Faculty Scholarship

In this Commentary, Professor Katherine Franke offers an analysis on Richard Delgado and Jean Stefancic's California's Racial History and Constitutional Rationales for Race-Conscious Decision Making in Higher Education and Rebecca Tsosie's Sacred Obligations: Intercultural Justice and the Discourse of Treaty Rights. These two Articles, she observes, deploy history for the purposes of justifying certain contemporary normative claims on behalf of peoples of color: affirmative action in higher education for Delgado and Stefancic, and sovereignty rights for native peoples in Tsosie's case. Franke explores the manner in which stories of past conquest and discrimination contribute to contemporary conceptions of racial …


Effects Of The Entomopathogenic Fungus Metarhizium Anisopliae On Glossina Fuscipes Fuscipes In Lake Victoria Island, Marco Brese Jan 2000

Effects Of The Entomopathogenic Fungus Metarhizium Anisopliae On Glossina Fuscipes Fuscipes In Lake Victoria Island, Marco Brese

All Master’s Theses

Glossina spp. Commonly known as tsetse flies are vectors of trypanosomes which can cause african human and animal trypanosomiases. The control of those diseases and their vector has shown some limitations. The 'dissemination technique' was considered to become a suitable method for tsetse control. It involves the contamination of flies with a lethal or sterilising agent and is based on the spread of the agent through natural contact events between tsetse flies. In the first part of the study, fluorescent pigment powder was used to detect whether there are regular contact events between specimens of g. Fuscipes fuscipes in the …


The Effect Of Heat On Fingertip Sensitivity Of Meat Processing Workers, Brian James Finder Jan 2000

The Effect Of Heat On Fingertip Sensitivity Of Meat Processing Workers, Brian James Finder

Dissertations and Theses @ UNI

Current research indicates that acute non-freezing cold exposure elicits short-term performance problems; namely reduced upper extremity temperature, blood flow, tactile sensitivity, and dexterity. However, various animal-related studies indicate that humans are at increased risk of incurring semi-permanent upper extremity nervous system dysfunction as a result of repeated cold exposure.

The purpose of this research was to examine various factors that may contribute to hand/arm nervous system impairment of individuals who work in a refrigerated meat-processing environment. The methodology used was primarily the Experimental Method and from studies conducted by other researchers, was driven by the following questions:

(1) How would …

Assessing The Classification Accuracy Of Digitized National Aerial Photography Program Imagery: Comparison With Botanical Data, Mark Arthur Alexander Jan 2000

Assessing The Classification Accuracy Of Digitized National Aerial Photography Program Imagery: Comparison With Botanical Data, Mark Arthur Alexander

Dissertations and Theses @ UNI

The ability to acquire and use remotely sensed data has revolutionized large-scale ecological studies by reducing dependence on difficult and expensive field survey techniques for acquisition of land use and land cover data. Multispectral satellite imagery, typically from the Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and the SPOT High Resolution Visible (HRV) instruments, has proven particularly valuable in surveying and classifying vegetation cover (Frank & Thorn, 1985). Further studies have concluded that alpine vegetation communities and habitats can be mapped successfully by including the geomorphic parameters of elevation, slope, and incidence when classifying remotely sensed data.

This research analyzes …


Photodecomposition Of Crystal Violet Dye In Water Solution And Suspensions Of Metal Oxides, Tatiana Yurievna Zakharian Jan 2000

Photodecomposition Of Crystal Violet Dye In Water Solution And Suspensions Of Metal Oxides, Tatiana Yurievna Zakharian

Dissertations and Theses @ UNI

Photodecomposition and photodecolorization of crystal violet dye were studied in water solution, hydrogen peroxide solution and suspensions of metal oxides. Spectroscopic evidence for the formation of methylated pararosanilines and demethylated derivatives of Michler's ketone as the reaction intermediates was obtained for the photodecomposition of crystal violet in water solution. The mechanism of formation of the intermediates was discussed in terms of charges of individual atoms calculated using Spartan software.

Photooxidation of crystal violet was shown to occur faster in hydrogen peroxide solution due to the higher oxidation potential of hydrogen peroxide and hydroxyl radicals. A mechanism similar to photooxidation in …


After The "Social Meaning Turn": Implications For Research Design And Methods Of Proof In Contemporary Criminal Law Policy Analysis, Bernard E. Harcourt Jan 2000

After The "Social Meaning Turn": Implications For Research Design And Methods Of Proof In Contemporary Criminal Law Policy Analysis, Bernard E. Harcourt

Faculty Scholarship

The social norm movement in criminal justice has received a lot of attention in academic and public policy circles. This essay critically examines social norm writings and explores some of the implications for methods of proof and research design in the social sciences. In the process, the essay offers an alternative theoretical approach. This alternative focuses on the multiple ways in which the social meaning of practices (such as juvenile gun possession, gang membership, or disorderly conduct) and the social meaning of policing techniques (such as juvenile snitching policies, youth curfews, or order-maintenance policing) may shape us as contemporary subjects …


The Constitutional Implications Of Human Cloning, Elizabeth Price Foley Jan 2000

The Constitutional Implications Of Human Cloning, Elizabeth Price Foley

Given the theoretical inevitability of human cloning, this Article attempts to fill a current intellectual void by providing an analysis of the most significant legal implications of cloning human beings. Part II sets forth the basic science behind cloning and how cloning differs from other, non-traditional forms of procreation such as in vitro fertilization and artificial insemination. Part III discusses the most commonly feared “science fiction” abuses associated with human cloning and current laws that may prevent such abuses from occurring. Part IV discusses the possible constitutional impediments to banning human cloning, including the First Amendment, the procreational liberty interest …


The Man On The Moon, Immortality, And Other Millennial Myths: The Prospects And Perils Of Human Genetic Engineering, George J. Annas Jan 2000

The Man On The Moon, Immortality, And Other Millennial Myths: The Prospects And Perils Of Human Genetic Engineering, George J. Annas

Faculty Scholarship

The year 2000 provides an opportunity to reflect and speculate on human life in the year 3000. We cannot know what human life will be like a thousand years from now, but we can and should think seriously about what we would like it to be. What is unique about human beings and about being human? What makes humans human? What qualities of the human species must we preserve to preserve humanity itself? What would a "better human" be like? If genetic engineering techniques work, are there human qualities we should try to temper, and ones we should try to …


The Identification Of Listening Styles Of Agricultural Curricula Majors Through The Administration Of The "Listening Styles Profile"., Jennifer L. Thomas Jan 2000

The Identification Of Listening Styles Of Agricultural Curricula Majors Through The Administration Of The "Listening Styles Profile"., Jennifer L. Thomas

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study was designed to determine listening preferences of undergraduate agricultural curricula majors attending West Virginia University during the1998 spring semester according to the Listening Styles Profile. The Listening Styles Profile defines listening preferences in four main categories: People-Oriented, Action-Oriented, Content-Oriented, and TimeOriented. The objectives of this study were to define listening preferences of undergraduate agricultural curricula majors and determine if listening styles are influenced by demographics. The demographic variables included: home location, rank, gender, grade point average, and major. It was concluded that agricultural curricula majors are predominantly People-Oriented listeners. Listener preferences of agriculture majors are not influenced by …


Economic Feasibility Of Trout Production In West Virginia: A Mixed Integer And Quadratic-Programming Analysis., Frank H. Fidler Iv Jan 2000

Economic Feasibility Of Trout Production In West Virginia: A Mixed Integer And Quadratic-Programming Analysis., Frank H. Fidler Iv

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this study was to determine the profitability and risk-return characteristics of trout production in West Virginia. A combination of primary data (from a producer survey) and secondary data (from published sources and expert opinion) was used. Two sets of models (mixed-integer and quadratic-programming/portfolio) were estimated. Raceways and tanks were the two types of systems analyzed, for three different production capacities. The alternatives for the portfolio analysis included investment in a CD (to represent opportunity cost), food-fish production for sale to processors, and recreational or fee fishing. Results show that as production levels increase, raceway systems are generally …


Symposium: Regulatory And Liability Considerations, Michael S. Baram, Ellen Flannery, Patricia Davis, Gary Marchant Jan 2000

Symposium: Regulatory And Liability Considerations, Michael S. Baram, Ellen Flannery, Patricia Davis, Gary Marchant

Faculty Scholarship

You can tell from remarks by prior speakers that regulatory approvals and liability prevention are of critical importance to progress in biomaterials. Gene therapy trials and the tragic outcomes of some of those trials have raised the specter of government suspension of clinical studies, termination of funding, and potential liability for personal injury under malpractice or products liability doctrines. Regulatory requirements and the terms of research grants and contracts have to be very carefully addressed by organizations testing, developing, making, selling and using biomaterials, biotechnology, and medical devices. However, many regulatory requirements are incomplete, ambiguous and confusing because the agencies …

Herbert Wechsler And The Criminal Law: A Brief Tribute, Harold Edgar Jan 2000

Herbert Wechsler And The Criminal Law: A Brief Tribute, Harold Edgar

Faculty Scholarship

The great English architect Christopher Wren is buried in his most famous church, St. Paul's London. The inscription on his memorial stone concludes with the words: Lector, si monumentum requiris, circumspice. Reader, if you seek his monument, look around you.

That instruction serves well those who would appraise and honor Herbert Wechsler's contributions to American criminal law. When he joined the Columbia Law School faculty in 1933, this school did not teach criminal law and much of the profession thought the topic was not worth studying.' What fabulous good fortune it was that Herb thought otherwise. Throughout a long and …


Environmental Justice And Natural Areas Protection Trends & Insight, Michael B. Gerrard Jan 2000

Environmental Justice And Natural Areas Protection Trends & Insight, Michael B. Gerrard

Faculty Scholarship

There are 3,119,963 square miles in the continental United States. That sounds like plenty of space to put just about anything. However, when the facility seeking a home is environmentally controversial, finding even one square mile can seem almost impossible.

This country is now in its third major era in making siting decisions. The first era – unconstrained siting – lasted until the late 1960s. Then began the second era – protecting natural areas. In the early 1990s, we embarked upon a third era – environmental justice. The growing tensions between protecting natural areas and achieving environmental justice suggest that …


Drug Treatment Courts And Emergent Experimentalist Government, Michael C. Dorf, Charles F. Sabel Jan 2000

Drug Treatment Courts And Emergent Experimentalist Government, Michael C. Dorf, Charles F. Sabel

Faculty Scholarship

Despite the continuing "war on drugs," the last decade has witnessed the creation and nationwide spread of a remarkable set of institutions, drug treatment courts. In drug treatment court, a criminal defendant pleads guilty or otherwise accepts responsibility for a charged offense and accepts placement in a court-mandated program of drug treatment. The judge and court personnel closely monitor the defendant's performance in the program and the program's capacity to serve the mandated client. The federal government and national associations in turn monitor the local drug treatment courts and disseminate successful practices. The ensemble of institutions, monitoring, and pooling exemplifies …


Optimal Standardization In The Law Of Property: The Numerus Clausus Principle, Thomas W. Merrill, Henry E. Smith Jan 2000

Optimal Standardization In The Law Of Property: The Numerus Clausus Principle, Thomas W. Merrill, Henry E. Smith

Faculty Scholarship

A central difference between contract and property concerns the freedom to "customize" legally enforceable interests. The law of contract recognizes no inherent limitations on the nature or the duration of the interests that can be the subject of a legally binding contract. Certain types of promises – such as promises to commit a crime – are declared unenforceable as a matter of public policy. But outside these relatively narrow areas of proscription and requirements such as definiteness and (maybe) consideration, there is a potentially infinite range of promises that the law will honor. The parties to a contract are free …


Fox Hunting, Pheasant Shooting And Comparative Law, Alan Watson, Khaled Abou El Fadl Jan 2000

Fox Hunting, Pheasant Shooting And Comparative Law, Alan Watson, Khaled Abou El Fadl

Scholarly Works

The Roman jurists, ancient rabbis and Muslim jurists were very different people. Above all, the rabbis and Muslim jurists were engaged on a search for law as truth. And the Roman jurists were much more obviously upper-class gentlemen.91 But the similarities are great. All three had a passion for legal interpretation. They delighted in discussing hypothetical cases. They chased after solutions by ways of reasoning devised by themselves. Practical utility, while present, was in the background. At times, to outsiders, their opinions seem outr6, even callous, remote from reality. They have little interest in what actually happens in court: their …

Limaria Hians (Mollusca: Limacea): A Neglected Reef-Forming Keystone Species, J. M. Hall-Spencer, P. G. Moore Jan 2000

Limaria Hians (Mollusca: Limacea): A Neglected Reef-Forming Keystone Species, J. M. Hall-Spencer, P. G. Moore

School of Biological and Marine Sciences

1. The case is made for recognition of the marine bivalve Limaria hians as a reef-forming species, which plays a key architectural role in certain benthic communities around the United Kingdom and Ireland. 2. This species uses byssal threads to construct nests that can coalesce to form reefs that cover hectares of seabed, contain multiple conspecifies and bind sediment. In so doing, L. hians modifies physical, chemical and biological processes at the sediment-water interface. 3. Such nests support a high diversity of associated organisms in coarse-grade sediments (19 species of algae and 265 species of invertebrates from six discrete nests …

A Checklist And Distribution Maps Of The Amphibians And Reptiles Of South Dakota, Royce E. Ballinger, Justin W. Meeker, Marcus Thies

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Fourteen species of amphibians and 30 species of reptiles are documented from South Dakota, based on the examination of 7,361 museum specimen records. No species of the herpetofauna is endemic to the state, which contains a mixture of species from especially the southern and western regions of the United States. Four amphibians (Ambystoma tigrinum, Bufo cognatus, Pseudacris triseriata, and Rana pipiens) and three reptiles (Chrysemys picta, Heterodon nasicus, and Thamnophis radix) occur statewide in appropriate habitats. Three amphibians and 11 reptiles reach their northern distributional limits in the state, and two amphibians …


A Floristic Study And Species Checklist For The Republican River Valley In Nebraska, With Emphasis On Plants Of Concern For Conservation, Steven J. Rothenberger Jan 2000

A Floristic Study And Species Checklist For The Republican River Valley In Nebraska, With Emphasis On Plants Of Concern For Conservation, Steven J. Rothenberger

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A botanical survey of the Republican River Valley in Nebraska was initiated during the 1995 growing season and continued through 1998. A major objective of this study was to discover and tabulate rare plants (as designated by the Nebraska Natural Heritage Program), but a general floristic study was also completed. Natural areas, selected because of species composition or location, were identified and described. The study area is characterized by a high degree of human disturbance. Most county floras, with the exception of Webster, are poorly represented. Seven species of conservation concern are reported, which is 1.4% of the total collected …


Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman Jan 2000

Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

New distributional records are presented for 20 species of mammals in Nebraska. The majority of these records appear to represent changes in geographic distribution rather than just better sampling in poorly known areas. One group of mammals, including the opossum, northern myotis, evening bat, red bat, woodchuck, white-footed mouse, and gray fox, is expanding westward, probably in response to increasing woodlands along river systems. Another group, including the meadow vole, masked shrew, and least weasel, is expanding southward, possibly in response to new prey species and changing microclimates. The eastern woodrat appears to be expanding northward in eastern Nebraska. The …


Effects Of Age And Group Size On Habitat Selection And Activity Level In Xenopus Laevis Tadpoles, Danielle R. Golden, Geoffrey R. Smith, Jessica E. Rettig Jan 2000

Effects Of Age And Group Size On Habitat Selection And Activity Level In Xenopus Laevis Tadpoles, Danielle R. Golden, Geoffrey R. Smith, Jessica E. Rettig

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

We experimentally examined the effects of age and group size on habitat selection and activity level in Xenopus laevis tadpoles. Tadpoles were introduced into an experimental arena at two ages (early and late) and at three group sizes (one, two, and six tadpoles). Group size did not affect habitat selection or activity level. Late tadpoles were more active and used the bottom of the arena more than early tadpoles. Our results suggest that an intrinsic cue (age) is important in determining the behavior of these tadpoles.
