Specifying Interdatabase Dependencies In A Multidatabase Environment, Marek Rusinkiewicz, Amit P. Sheth, George Karabatis

Kno.e.sis Publications

The problem of interdatabase dependencies and the effect they have on applications updating interdependent data are addressed. A model that allows specifications of constraints among multiple databases in a declarative fashion is proposed. The separation of the constraints from the application programs facilitates the maintenance of data constraints and allows flexibility in their implementation. It allows investigation of various mechanisms for enforcing the constraints, independently of the application programs. By grouping the constraints together, it is possible to check their completeness and discover possible contradictions among them. The concepts of polytransactions, which use interdatabase dependencies to generate a series of …

Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer

Feeding Behavior Collection

Individual daily consumption of supplementary solid food ('creep feed') was measured from Day 10 to weaning at Day 28 for 39 piglets in four litters, and its relationship to body weight and weight gain up to Day 42 was investigated. Individual consumption was measured by combining the weight of the feed removed from the dispensers (monitored electronically) and a video image of piglet activity at the feeder. Creep feed consumption varied greatly, both between and within litters. On average, pigs began feeding on Day 12 (range Day 10-28), intake was relatively low (usually < 5 g day ^‒1) until Day 20 but increased …

Age Differences In The Maintenance And Restructuring Of Movement Preparation, Paul Amrhein, George Stelmach, Noreen Goggin

Department of Psychology Faculty Scholarship and Creative Works

In 2 experiments, 56 elderly (aged 65–78 yrs) and young Ss (aged 20–28 yrs) performed simple reaction time (RT), choice RT, and movement plan restructuring tasks, using a stimulus precuing paradigm. In Exp 1, the precue display (200 ms) and preparation interval (250, 500, 750, or 1,000 ms) were experimentally determined. In Exp 2, the precue display interval was S determined. For the restructuring task, the precue specified the response on 75% of the trials, enabling movement plan preparation with respect to movement parameters of arm and direction. On remaining trials, the precue incorrectly specified the response, requiring movement plan …

Enhanced Attraction To Blood By Pigs With Inadequate Dietary Protein Supplementation, David Fraser, D. E. Bernon, R. O. Ball

Nutrition Collection

In two experiments, 60 individually penned growing pigs were exposed daily to two sections of cotton cord, one of which had been soaked with pigs' blood and subsequently dried, while the other was plain. The animals' preference for chewing-on the blood-impregnated cord was quantified by direct observation. When fed a standard "control" diet of corn, barley, and soybean meal with mineral and vitamin supplements, the pigs had a clear but modest preference for chewing the blood-impregnated cord. Omission of the protein supplement (soybean meal) from the diet for 4 wk led to a major increase in attraction to blood and …

Arkansas Cooperative Beef Bull Performance Test 1991, M. W. Eaton, A. E. Brown Jr., J. A. Hornsby, R. W. Parham, J. D. Shockey, W. C. Loe

Arkansas Agricultural Experiment Station Research Series

Performance testing of beef bulls was initiated to improve productivity of Arkansas beef cattle through breeding. This cooperative testing program provides cattlemen with reliable information for identifying animals with superior breeding value for the traits of production measured in the test. By using the information as a basis for herd sire selection, a breeder can greatly increase the chances of obtaining a bull that will sire rapid-gaining, more efficient, highquality calves. Such calves can increase profits for both the breeder and the feeder. This testing program provides information that is useful to financial institutes in arranging their lending programs and …

Use Of Pollen Concentration In Paleopharmacology: Coprolite Evidence Of Medicinal Plants, Karl Reinhard, Donny L. Hamilton, Richard H. Hevly

Karl Reinhard Publications

Nearly 2,400 plant species have been documented ethnographically as having medicinal value among Native Americans. Therefore, it is not surprising that evidence of medicinal plants appears in some of the over 1,000 coprolites analyzed from the southwestern U.S. Three medicinal species identified in pollen analysis of coprolites are discussed. Willow (Salix) is the most common analgesic in the Native American pharmacopoeia. Prehistoric use of this plant is documented in coprolites from Bighorn Cave in the Black Mountains of Arizona and also in a burial from the Mimbres Valley, New Mexico. Historically, Mormon tea (Ephedra) served as …

Kin Recognition In Vertebrates: What Do We Really Know About Adaptive Value?, Andrew R. Blaustein, Marc Bekoff, John A. Byers, Thomas J. Daniels

Sentience Collection

The ability of an animal to discriminate between kin and non-kin (kin recognition) has been the subject of numerous recent investigations. Grafen (Anim. Behav., 1990, 39, 42-54) recently reported that the evidence in support of kin recognition is weak and the data illustrating a preference for kin to associate in the laboratory may be more consistently explained as species recognition. It is suggested here, however, that in many cases it may be impossible to distinguish between species recognition and kin recognition, but in some cases, kin recognition seems apparent. It is also emphasized that very little is known about the …

The Effects Of Bilateral Injections Of Neuropeptide K Into The Medial Preoptic Area On Male Rat Copulatory Behavior, Peter Malen '91

Honors Projects

The first mammalian neuropeptide to be characterized was substance P (sP) , and it is now recognized that sP is a member of a structurally related family of peptides, the tachykinins. Extensive studies have demonstrated. that sP and some related tachykinin peptides play key roles as neurotransmitters and neuromodulators. The synthesis of different members of the tachykinin family is in part due to the modifications' of three sP-encoding preprotachykinin (PPT) mRNA's that are derived from a single sP gene. At least four tachykinin peptides can be synthesized as a result of these differential modifications including sP, neurokinin A, neuropeptide and …

Intracerebral Injections Of Substance P Fragments (5-11) And (1-7) Into The Dorsal Midbrain Central Gray Have No Effects On Lordosis Behavior In The Female Rat, Jodi K. Block '91

Honors Projects

Substance P (sP), a neuroactive peptide, has now been implicated in a wide range of behaviors. One in particular is female rat sexual behavior. Recently, it has been shown that bilateral injections of sP into the dorsal midbrain central gray (dMCG) of estrogen-primed female rats facilitate sexual behavior (lordosis). Uncertainty remains, however, concerning the mode of action of synaptically released sP. Indeed, most of our understanding of sP activity has revealed that its full structural sequence is not needed for biological activity. This has led to speculation that sP may be processed into one or more types of fragments before …

Effect Of Straw On The Behaviour Of Growing Pigs, David Fraser, P. A. Phillips, B. K. Thompson, T. Tennessen

Social Behavior Collection

The effects of straw on the behaviour of young growing pigs were studied in two experiments. In Experiment 1, group of three pigs, aged about 7 weeks, were housed in raised decks with or without straw bedding. Time-lapse video recording showed no major differences between treatments in the amount or daily pattern of overall activity and feeding. Detailed observations showed that bedding reduced the incidence of rooting and chewing on pen-mates, but had little effect on other social activities such as mounting and aggressive biting. Experiment 2 compared groups of eight growing pigs aged about 10 weeks, housed in floor …

On The Relationship Between Parsimonious Covering And Boolean Minimization, Venu Dasigi, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Minimization of Boolean switching functions is a basic problem in the design of logic circuits. The designer first comes up with a switching function expressed in terms of several binary input variables that satisfies the desired functionality, and then attempts to minimize the function as a sum of products or product of sums. It turns out that a sum of products form of a switching function that has no redundancy is a union of prime implicants of the function.

In this paper we would like to explicate some of the relationships of the boolean minimization problem to a formalization of …

On Serializability Of Multidatabase Transactions Through Forced Local Conflict, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth

Kno.e.sis Publications

The main difficulty in enforcing global serializability in a multidatabase environment lies in resolving indirect transitive conflicts between multidatabase transactions. Indirect conflicts introduced by local transactions are difficult to resolve because the behavior or even the existence of local transactions is not known to the multidatabase system. To overcome these problems, we propose to incorporate additional data manipulation operations in the subtransactions of each multidatabase transaction. We show that if these operations create direct conflicts between subtransactions at each participating local database system, indirect conflicts can be resolved even if the multidatabase system is not aware of their existence. Based …

Describing The Flora Of The United States: Botanies At Libraries In Syracuse, Dudley J. Raynal

The Courier

The first written descriptions of the flora of North America were those of sixteenth-century Europeans who marvelled at the botanical treasures brought to them by explorers of the New World. The earliest account of American natural history was that of the English botanical explorer Thomas Hariot who wrote his Briefe and True Re, port of the New Found Land of Virginia in 1590 after returning from an expedition arranged by Sir Walter Raleigh. Hariot carried to En, gland tubers, fruits, and seeds of plants previously unknown in Europe. Perhaps thirty different plant species had been introduced into Europe from the …

Review Of Colorado Flora: Eastern Slope By William A. Weber., Robert B. Kaul

Great Plains Research: A Journal of Natural and Social Sciences

All 2260 plant species of eastern-slope Colorado--from the continental divide east to the Nebraska and Kansas borders--can be identified using this book. That figure includes not only the native species but also the numerous introduced ones that survive without cultivation and often provide severe competition for the native flora. Much of Colorado's native plains flora was eliminated in the past century by plowing and by grazing livestock. It is largely replaced by a few durable native and many aggressive exotic species that thrive under those conditions, but remnants of the original flora exist on escarpments and in a few level …

Animals In Biomedical Research: The Undermining Effect Of The Rhetoric Of The Besieged, John P. Gluck, Steven R. Kubacki

Experimentation Collection

It is correctly asserted that the intensity of the current debate over the use of animals in biomedical research is unprecedented. The extent of expressed animosity and distrust has stunned many researchers. In response, researchers have tended to take a strategic defensive posture, which involves the assertation of several abstract positions that serve to obstruct resolution of the debate. Those abstractions include the notions that the animal protection movement is trivial and purely anti-intellectual in scope, that all science is good (and some especially so), and the belief that an ethical consensus can never really be reached between the parties.

Distributive Effects Of Forest Service Attempts To Maintain Community Stability, Steven E. Daniels, William F. Hyde, David N. Wear

Sociology, Social Work and Anthropology Faculty Publications

Community stability is an objective of USDA Forest Service timber sales. This paper examines that objective, and the success the Forest Service can have in attaining it, through its intended maintenance of a constant volume timber harvest schedule. We apply a three-factor, two-sector modified general equilibrium model with empirical evidence from the timber-based counties of western Montana. Departure from a market responsive timber policy can have positive impacts on the wood products sector, but the net effects on the local community are very small. The costs to the public treasury of pursuing such a policy dwarf these small community benefits.

Introgression Of Coyote Mitochondrial Dna Into Sympatric North American Gray Wolf Populations, Niles Lehman, Andrew Eisenhawer, Kimberly Hansen, L. David Mech, Rolf O. Peterson, Peter J. P. Gogan, Robert K. Wayne

USGS Northern Prairie Wildlife Research Center

Mitochondrial DNA (mtDNA) genotypes of gray wolves and coyotes from localities throughout North America were determined using restriction fragment length polymorphisms. Of the 13 genotypes found among the wolves, 7 are clearly of coyote origin, indicating that genetic transfer of coyote mtDNA into wolf populations has occurred through hybridization. The transfer of mtDNA appears unidirectional from coyotes into wolves because no coyotes sampled have a wolf-derived mtDNA genotype. Wolves possessing coyote-derived genotypes are confined to a contiguous geographic region in Minnesota, Ontario, and Quebec, and the frequency of coyote- type mtDNA in these wolf populations is high (> 500%). The …

Reflective Ethology, Applied Philosophy, And The Moral Status Of Animals, Marc Bekoff, Dale Jamieson

Experimental Research and Animal Welfare Collection

Currently there is an unprecedented interest in ethological studies of nonhuman animals. Much of this interest is motivated by a desire to learn more about animals themselves. For scientists assuming this stance, a secondary goal is to use this knowledge to assess the place of humans in the natural order of things, stressing continuity or discontinuity depending on one's views. Others, however, study animals primarily to apply this knowledge to human behavior. We argue that behavioral research demands the rigorous application of methods that are minimally harmful to the animals being studied. We argue for a moderate, but rigorous and …

Refuge Land Acquisition: Helping Preserve Back Bay's Wildlife Heritage, Julia Herrick, Ben Mathias, Janet Taylor

V. Poster Abstracts

The once-renowned waterfowl populations and bass fishery of Back Bay, Virginia have declined dramatically in recent years. Lands surrounding Back Bay are increasingly threatened by on-going and potential land development. These lands serve as an important filter for pollutant and sediment-laden runoff from adjacent areas. The boundary of the Back Bay National Wildlife Refuge was expanded in 1989 to include an additional 6,340 acres of brackish marsh, forested swamp, and "critical edge" upland habitat, important to a variety of wildlife species and for its natural filtering effect. Within the U.S. Fish and Wildlife Service's policy of working with willing sellers, …

Dietary And Parasitological Analysis Of Coprolites Recovered From Mummy 5, Ventana Cave, Arizona, Karl Reinhard, Richard H. Hevly

Karl Reinhard Publications

Four coprolites were excavated with Burial 5 at Ventana Cave. a partially mummified five-year-old child. Two coprolites were granular and dark in color and two were fibrous and light in color. The coprolites are remains of the child's intestinal contents and were submitted for dietary and parasitological analysis. No parasites were found. The fibrous coprolites proved to be remains of highly masticated mesquite pods (Prosopis). The granular coprolites consist of seeds of saguaro cactus (Carnegiea gigantea). Pollen analysis reveals two dietary pollen types, both derived from cactus. No evidence of cultivated plants except for a trace amount of …
