The Ecology And Evolution Of Spatial Memory In Corvids Of The Southwestern Usa: The Perplexing Pinyon Jay, Russell P. Balda, Alan Kamil

Papers in Behavior in Biological Sciences

The corvids of the southwest possess many adaptations for the harvest, transport, caching and recovery of pine seeds. However, there is a large degree of between-species variation in the distribution of these traits. These corvids have a well-accepted phylogeny (Hope, 1989), live within close proximity to one another and have relatively well-known natural histories. They therefore present an excellent opportunity to apply the comparative method (Kamil, 1988) to the study of these species differences (Balda et al., 1997). The comparative method for the study of adaptation and evolution of behavioral traits begins with a careful study of the natural histories …

Preface: Animal Cognition In Nature, Russell P. Balda, Irene M. Pepperberg, Alan Kamil

Papers in Behavior in Biological Sciences

This volume, Animal Cognition in Nature, is the result of an ongoing synthesis of several ideas that were considered revolutionary, if not heretical, in the 1960s. At that time, animal behavior, whether studied in field or laboratory, by ethologists or psychologists, was generally interpreted as the result of simple processes relating specific stimuli to specific behaviors. Examples from that time include S–R models, sign stimuli, IRMs, etc. Theoretical constructs such as mental representations, memory or attention were avoided. Today, students of animal behavior work in an entirely different atmosphere. This is the result of several developments.

One of these developments …

Telomerase Expression In Chickens: Constitutive Activity In Somatic Tissues And Down-Regulation In Culture, Ranga N. Venkatesan, Carolyn Price

Department of Biochemistry: Faculty Publications

Although human and rodent telomeres have been studied extensively, very little is known about telomere dynamics in other vertebrates. Moreover, our current dependence on mice as a model for human tumorigenesis and aging poses a problem because human and mouse telomere biology is very different. To explore whether chickens might provide a more useful model, we have examined telomerase activity and telomere length in chicken tissues as well as in primary cell cultures. Although chicken telomeres resemble human telomeres in that they are 8–20 kb in length, the distribution of telomerase activity in chickens resembles what is found in mice. …

Differential Gene Expression In Insects: Transcriptional Control, Lawrence G. Harshman, Anthony A. James

School of Biological Sciences: Faculty Publications

Studies on transcriptional control of gene expression play a pivotal role in many areas of biology. In non-Drosophilid insects, the cuticle, chorion, immune response, silk gland, storage proteins, and vitellogenin are foci for advances in basic research on promoter elements and transcription factors. Insects offer other advantages for gene regulation studies, including the availability of applied problems. In non-Drosophilid insects, the most serious problem for transcriptional control studies is the lack of homologous in vivo expression systems. Once this deficiency is addressed, the full impact of research on transcription control will be realized throughout the field of entomology.

Evolutionary Change In A Receiver Bias: A Comparison Of Female Preference Functions, Alexandra Basolo

School of Biological Sciences: Faculty Publications

Female poeciliid fishes of the sister genera Xiphophorus and Priapella share a preference for males with swords, despite phylogenetic information suggesting that swords arose in Xiphophorus after the divergence of the two genera. This study examines the strength of sword and body-size preferences in a representative of both genera. A comparison of the preference functions reveals that the strength of the preference favoring a sword in P. olmecae is significantly stronger than that in X. helleri. This result demonstrates that the pre-existing bias is not evolutionarily fixed, and that there has been change in the bias favoring the sword, …

Substituted Polythiophenes From Highly Reactive Zinc Reagents, Reuben D. Rieke

Department of Chemistry: Faculty Publications

A novel Zerovalent zinc species and an organozinc reagent are disclosed. The zerovalent zinc species is directly pro duced by reaction of a reducing agent on a zinc salt, preferably Zn(CN)₂. The organozinc reagent results from the reaction of the zerovalent zinc species and an organic compound having one or more stable anionic leaving groups. These organozinc reagents include a wide spectrum of functional groups in the organic radical, and are useful in a variety of reactions schemes.

Mummies And Mummification Practices In The Southern And Southwestern United States, Mahmoud Y. El-Najjar, Thomas M. J. Mulinski, Karl Reinhard

Karl Reinhard Publications

Mummification was not intentional for most North American prehistoric cultures. Natural mummification occurred in the dry areas of North America, where mummies have been recovered from rock shelters, caves, and overhangs. In these places, corpses desiccated and spontaneously mummified. In North America, mummies are recovered from four main regions: the southern and southwestern United States, the Aleutian Islands, and the Ozark Mountains of Arkansas. This chapter is limited to a discussion of burial practices and a tabulation of the location of mummies in the southwestern United States with some comments on mummies of the southern United States, including the Ozarks.

New Investigative Techniques [In Mummies, Disease & Ancient Cultures], Theodore A. Reyman, Henrick Nielsen, Ingolf Thuesen, Derek N. H. Notman, Karl Reinhard, Edmund Tapp, Tony Waldron

Karl Reinhard Publications

In this chapter, we shall see how the amplification of minute amounts of genetic material by the polymerase chain reaction (PCR) has enabled researchers to identifY both native and infectious DNA in these bodies. The use of amplified bacterial and viral DNA may turn out to be Aidan Cockburn's 'magic bullet' for solving some of the mysteries of infectious disorders in ancient populations. In the same fashion, native DNA may give us clues to a variety of genetic abnormalities that existed in those distant times. These newer techniques will be the focus of the revised technical section in this second …

Human Dental Microwear Caused By Calcium Oxalate Phytoliths In Prehistoric Diet Of The Lower Pecos Region, Texas, Dennis Danielson, Karl Reinhard

Karl Reinhard Publications

Recent research demonstrates that silica phytoliths of dietary origin are associated with microwear of human teeth. Previous research has shown that severe enamel microwear and dental wear characterizes Archaic hunter-gatherers in the lower Pecos region of west Texas. Calcium oxalate crystals are especially common in Archaic coprolites. The vast majority are derived from prickly pear and agave, which were the dietary staples in west Texas for 6,000 years. The calcium oxalate phytoliths are harder than enamel. Therefore, calcium oxalate crystals are the most likely source of previously documented dental microwear and wear in the lower Pecos region.Am J Phys Anthropol …

Martineau In Current Introductory Textbooks: An Empirical Survey, Michael R. Hill

Department of Sociology: Faculty Publications

Harriet Martineau is now making significant appearances in introductory textbooks used in the u.s. and Canada. There was a time, not so long ago, when only the Hess, Markson, and Stein "intro text" made note of Harriet Martineau. Although ample room for progress remains, the situation is improving.

I made a comprehensive effort, during the 1997 meetings of the American Sociological Association in Toronto, Canada, to survey all introductory sociology textbooks that were prominently displayed by publishers in their booths in the Sheraton Exhibition Hall. Some ninety publishers displayed textbooks, journals, and sociological monographs. Of forty-three works clearly identifiable and …

Loading Capacity And Chromatographic Behavior Of A Porous Graphitic Carbon Column For Polychlorinated Biphenyls, Kathy R. Echols, Robert W. Gale, Kevin Feltz, Jerome O’Laughlin, Donald E. Tillitt, Ted R. Schwartz

United States Geological Survey: Staff Publications

A porous graphitic carbon column (Hypercarb) was used for the fractionation of polychlorinated biphenyls (PCBs) into classes of 2-4 ortho chlorines, 1 ortho chlorine and 0 ortho chlorine congeners. A method was developed that combined the fractionation of PCBs, polychlorinated dibenzo-p-dioxins and dibenzofurans in a variety of biotic environmental samples. Many of these samples have high concentrations of PCBs which cause fractionation problems as adsorption sites on the graphitic surface are occupied. The loading capacity of the column for PCBs was determined by injecting up to 1 mg of total PCBs and monitoring changes in chromatographic behavior of …

Continuous Lake-Sediment Records Of Glaciation In The Sierra Nevada Between 52,600 And 12,500 14c Yr B.P., Larry Benson, Howard M. May, Ronald C. Antweiler, Terry I. Brinton, Michaele Kashgarian, Joseph P. Smoot, Steve P. Lund

United States Geological Survey: Staff Publications

The chemistry of the carbonate-free clay-size fraction of Owens Lake sediments supports the use of total organic carbon and magnetic susceptibility as indicators of stadial-interstadial oscillations, Owens Lake records of total organic carbon, magnetic susceptibility, and chemical composition of the carbonate-free, clay-size fraction indicate that Tioga glaciation began ~24,500 and ended by ~13,600 ¹⁴C yr B.P. Many of the components of glacial rock flour (e.g., TiO₂ , MnO, BaO) found in Owens Lake sediments achieved maximum values during the Tioga glaciation when valley glaciers reached their greatest extent. Total organic carbon and Si02 (amorphous) concentrations reached minimum values …

Early Life History Stages Of Gulf Sturgeon In The Suwannee River, Florida, Kenneth J. Sulak, James P. Clugston

United States Geological Survey: Staff Publications

Egg sampling confirmed that Suwannee River Gulf sturgeon Acipenser ozyrinchus desotoi, a subspecies of Atlantic sturgeon A. o. oxyrinchus use the same spawning site at river kilometer (rkm) 215 from the mouth of the river each year. Forty-nine eggs were recorded in 1995, and 368 were recorded in 1996. Spawning began 4-7 d after the March new moon in both years and lasted 10-11 d; in 1996, a second 10-d spawning round began on the April new moon. Developmental synchrony among eggs recovered suggested serval discrete spawning events in both years. Total eggs deposited for three 1996 sampling days …

An Investigation Of The Amount Of Emphasis Placed On Content And Delivery By Instructors Of Public Speaking, Paul J. Siddens Iii

Faculty Publications

A study examined how much emphasis instructors of public speaking place on content and delivery when teaching and delivering oral and written critiques. The study sought to determine whether when teaching a hybrid introduction to communication course; or public speaking course; instructors are challenged with teaching their students about issues related to the content of the speech; such as the introduction and conclusion; organization; supporting evidence; and issues related to physical and vocal delivery such as appearance; gestures; eye contact; volume; rate; and vocal variety. This was a pilot study to test the research questions; survey instrument; and methodology used …

Operating An Acoustic Doppler Current Profiler Aboard A Container Vessel, C. N. Flagg, G. Schwartze, E. Gottlieb, Hans Thomas Rossby

Graduate School of Oceanography Faculty Publications

Since October 1992 an acoustic Doppler current profiler (ADCP) has been in near-continuous operation on board a 118-m-long container vessel, the container motor vessel Oleander, which operates on a weekly schedule between Port Elizabeth, New Jersey, and Hamilton, Bermuda. The ADCP collects information on currents from the surface to depths as great as 404 m depending on zooplankton concentrations, ship’s speed, sea state conditions, and the ship’s load factor. The southbound transits provide more and better data because the ship is loaded and rides deeper resulting in less bubble formation and entrainment underneath the vessel.

Gambling On The Internet, Aaron Craig

Computer Law Review and Technology Journal

This article analyzes current proposals to regulate gambling on the Internet and suggests that their flaws stem primarily from a failure to appreciate the complexity of the vice/economic gain dichotomy that has been incorporated in American gambling regulatory policy. Americans have historically prohibited some forms of gambling while tolerating others. An Internet gambling regulatory system should view the Internet as a medium across which current gambling policies should be extended. Regimes that legalize all forms of gambling on the Internet are politically untenable and unwise. Proposals to outlaw all forms of gambling fail to recognize the Government's interest in permitting …

The Gift Of Language, Joseph Vining

Articles

Style and substance cross-are genetically related as we now might want to say. Each draws on and is implied by the other. One point at which they cross is our sense of the nature of human language, what language is and can be, what it is not and can never be. The language of law is part of human language. Law is a distinctive form of thought, but it lives in human language. "Rule" might be thought synonymous with "law," but for all its talk of rules, the practice of law does not begin with a descriptive statement, or a …

Thoughts From Across The Water On Hearsay And Confrontation, Richard D. Friedman

Articles

This article draws on the history of the hearsay rule, and on recent decisions of the European Court of Human Rights, to argue that the right to confrontation should be recognised as a basic principle of the law of evidence, and that aspects of the Law Commission's proposals for reform of the hearsay rule, and of the Home Office's proposals for restrictions on the right of cross-examination, are therefore unsatisfactory.

Built On Lies: Preliminary Reflections On Evidence Law As An Autopoetic System, Richard O. Lempert

Articles

This Symposium on Truth and Its Rivals seems most concerned with what one might think of as the "output" side of evidence law that is, whether the rules of evidence enhance the likelihood that trial verdicts will capture the true state of the matter giving rise to the litigation. From this perspective, the legitimate rivals to truth are values that may justify decisions that eclipse the truth. The most obvious examples are rules of privilege, which allow probative information to remain concealed even where it is essential to accurate fact finding.

Contracting In Cyberspace, Jeff C. Dodd, James A. Hernandez

Computer Law Review and Technology Journal

Cyberspace law has started to take some shape as lawyers and merchants increasingly look to the same models and structures for guidance. Proposed statutes dealing directly with cyberspace contracting issues are working their way through the process of uniform and legislative law making. A few of these statutory laws have already made it through the gauntlet.4 Although this unsystematic growth through practice has led to a motley collection of legal standards governing cyberspace contracting, most of the issues that these standards purport to deal with relate to only five root problems:

(a)   Authority. When is the contract "my" contract? What …

Nurse Practitioner Utilization Of Computer Technologies In Practice, Jo Ann Dumas

Master's Projects

The research demonstrated that nurse practitioners (NP's) underutilized computer applications that would improve client care in their practice. Computer use by NP's in public clinics, private practice, health maintenance organizations (HMO 's) and other settings in the greater San Francisco Bay area was described. The descriptive research used a non-experimental design. Subjects were 200 nurse practitioners. The survey instrument was developed by the researcher. Of 104 respondents, 86 (83%) used computers at work. "Obtaining client records from other agencies or departments" was rated the most useful computer application for improving client care. "Internet searches" was rated the next most useful …

Does The Congestive Heart Failure Program Improve Patient's Functional Health Status?, Lily Lu

Master's Projects

Congestive heart failure (CHF) is a significant health problem in the U.S. There are over 2 million Americans diagnosed with CHF, with 200,000 CHF related deaths every year. A CHF Comprehensive Care Program in a Northern California medical center began in August, 1997 to case manage and educate CHF patients and their family members. The program educated CHF patients to self-manage the chronic condition by daily weight, low sodium diet, medication adherence, activity and rest balance, and daily exercise. This study used a one group. Pre and post test study design to evaluate the effectiveness of the CHF program. The …

It's a curious broadside, a work of austere graphics and polite prose far removed from the mischievous engravings and bawdy ballads usually appearing on such sheets. Drawn from an address that 345 printers had signed and 138 had presented to the queen, the original text was committed to parchment "and accompanied by a Copy surperbly printed on white Satin, edged with white Silk Fringe, backed with purple Satin, and mounted in an Ivory Roller with appropriate Devices." Even in the published version, the arch is full of intricately detailed work. The printers took pride in their craftmanship: "This Specimen of …

Filtration Modeling Of A Plate-And-Frame Press, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The porosity distribution and filtrate production during cake filtration in a plate-and-frame filter press were simulated mathematically. The model considered filtration that occurs after the filling process, not filtration that occurs as the suspension fills the cell. Governing equations for the temporal porosity distribution were developed for a plateand- frame press. The governing equations were solved numerically using an alternating-direction-implicit scheme. Appropriate initial and boundary conditions were determined based on characteristics of the plate-and-frame press and of the suspension properties. Predicted porosity and velocity distributions were calculated for assumed constitutive parameters.

Freeing The Tortious Soul Of Express Warranty Law, James J. White

Articles

I suspect that most American lawyers and law students regard express warranty as neither more nor less than a term in a contract, a term that is subject to conventional contract rules on formation, interpretation, and remedy. Assume, for example, that a buyer sends a purchase order to a seller and the purchase order specifies the delivery of 300 tons of "prime Thomas cold rolled steel." The acknowledgment also describes the goods to be sold as "prime Thomas cold rolled steel." Every American lawyer would agree that there is a contract to deliver such steel and furthermore would conclude that …
