Computationalism And The Problem Of Other Minds, Stuart M. Glennan Jan 1995

Computationalism And The Problem Of Other Minds, Stuart M. Glennan

Scholarship and Professional Work - LAS

In this paper I discuss Searle's claim that the computational properties of a system could never cause a system to be conscious. In the first section of the paper I argue that Searle is correct that, even if a system both behaves in a way that is characteristic of conscious agents (like ourselves) and has a computational structure similar to those agents, one cannot be certain that that system is conscious. On the other hand, I suggest that Searle's intuition that it is “empirically absurd” that such a system could be conscious is unfounded. In the second section I show …

Artificial Intelligence Techniques Applied To Automatic Ship Guidance, Neil A.J. Witt Jan 1995

Artificial Intelligence Techniques Applied To Automatic Ship Guidance, Neil A.J. Witt

Other Faculty of Science and Engineering Theses

It has been estimated that over eighty per cent of marine accidents have been caused by operator error. The skills of the operator in the handling of the vessel are variable and are subject to external influences. Over the past seventy years many advances have been made in the field of ship control. Early developments on proportional controllers have led to today's modern control systems which have interfacing capabilities with electronic navigation equipment. This research investigates traditional control methodologies and introduces the concept of applying artificial intelligence (AI) methods to the ship guidance problem. Research into AI techniques has been …

Evidence Of The Establishment Of Cotesia Flavipes (Hymenoptera: Braconidae) In Continental Africa, C. O. Omwega, S. W. Kimani, W. A. Overholt, C. K.P.O. Ogol Jan 1995

Evidence Of The Establishment Of Cotesia Flavipes (Hymenoptera: Braconidae) In Continental Africa, C. O. Omwega, S. W. Kimani, W. A. Overholt, C. K.P.O. Ogol

All Peer-Reviewed Publications

Cotesia flavipes Cameron has been released several times in Africa for biological control of gramineous stem borers. Establishment has been reported on the Indian Ocean islands of Mauritius, Réunion and Madagascar, however, several attempts to introduce C. flavipes into continental Africa are reported to have failed. Recently, several cocoon masses of C. flavipes were recovered from south-western Kenya where the parasitoid was never released. Identifications of the parasitoids from south-western Kenya were based on morphological characters, allozyme frequencies, and mating experiments with laboratory populations of C. flavipes. It is hypothesized that C. flavipes became established from individuals escaping from a …

All Peer-Reviewed Publications

The bioactivity of materials from the leaves of Ocimum kilimandscharicum was tested against Sitophilus zeamais Mots chulsky (Coleoptera: Curculionidae), Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) and Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) in maize and sorghum grains in the laboratory. Exposure of adults of the three insect species to dried ground leaves and essential oil extract of O. kilimandscharicum induced 100% mortality after 48 h. Fresh and dried whole leaves were not toxic to Sitophilus zeamais or R. dominica. Grains treated with dried ground leaves and essential oil extract caused significant reductions in the number of progeny and survival rate of all …

Linkage Relationships Among Loci Controlling Morphological Traits In Cowpea (Vigna Unguiculata (L.) Walp.), S. M. Githiri, P. M. Kimani, R. S. Pathak

All Peer-Reviewed Publications

Linkage among loci controlling various morphological traits in cowpea were determined using F2 progenies. Data were collected on individual plants of four crosses segregating for several loci. Recombination estimates between the following pairs of loci were as follows: Sw (swollen vs normal stem base)-Fbc (cream vs green flower buds) (41±4.8%), Pus(purple vs green stems)-Cbr (cocoa-brown vs straw-yellow dry pods) (31±5.7%), Pup(purple vs green immature pods)-Cbr (30±5.7%), Pus-Pup (4±1.5%), Ndt (non-determinate vs determinate)-Pd (peduncle colour) (26±2.8%), Ndt-Hg (semi-erect vs erect plant type) (26±2.8%), Pt(purple vs green pod tips)-Bk (greyish-black vs straw-yellow dry pods) (19±2.4%) and Hg-Bpd (normal vs branching peduncle (24±9.5%). …

Biosystematics Of The Cotesia Flavipes Complex (Hymenoptera: Braconidae): Interspecific Hybridization, Sex Pheromone And Mating Behaviour Studies, Susan W. Kimani, William A. Overholt Jan 1995

Biosystematics Of The Cotesia Flavipes Complex (Hymenoptera: Braconidae): Interspecific Hybridization, Sex Pheromone And Mating Behaviour Studies, Susan W. Kimani, William A. Overholt

All Peer-Reviewed Publications

Mating behaviour, sex pheromone attraction and reciprocal breeding of Cotesia flavipes Cameron (Hymenoptera: Braconidae), C. sesamiae (Cameron) and C. chilonis (Matsumura) were studied. These three putative species comprise the Cotesia flavipes complex. Wing fanning and antennal vibration were the initial courtship signals from the males. Antennal stroking by the male was also an important contact signal and a prerequisite to successful mounting and copulation. Interspecific crosses revealed that males of C. flavipes exhibited courtship behaviour, and mounted and copulated with females of C. chilonis and C. sesamiae; the males transferred sperm but progeny from these crosses did not include females. …

Repellent And Acaricidal Properties Of Ocimum Suave Against Rhipicephalus Appendiculatus Ticks, Esther N. Mwangi, Ahmed Hassanali, Suliman Essuman, Edward Myandat, Lambert Moreka, Mark Kimondo Jan 1995

Repellent And Acaricidal Properties Of Ocimum Suave Against Rhipicephalus Appendiculatus Ticks, Esther N. Mwangi, Ahmed Hassanali, Suliman Essuman, Edward Myandat, Lambert Moreka, Mark Kimondo

All Peer-Reviewed Publications

An oil extracted from the leaves of a tropical shrub Ocimum suave was found to repel as well as kill all stages of the tick Rhipicephalus appendiculatus. In an in vitro bioassay for the larvae, the LC50 of the oil in liquid paraffin was 0.024%. A 10% solution was found to kill all immatures and more than 70% of adults feeding on rabbits. Rabbits were protected for 5 days against attaching larvae using a 10% solution. Preliminary experiments undertaken with cattle kept in the field suggest that the oil may have potential in tick control, and a role in integrated …

Importance Of Adult Food Sources To Host Searching Of The Larval Parasitoid Microplitis Croceipes, Keiji Takasu, W. J. Lewis Jan 1995

Importance Of Adult Food Sources To Host Searching Of The Larval Parasitoid Microplitis Croceipes, Keiji Takasu, W. J. Lewis

All Peer-Reviewed Publications

We conducted field experiments to determine the effects of food availability and parasitoid hunger on the searching behavior of Microplitis croceipes (Cresson) (Braconidae; Hymenoptera) in small corn and soybean plots. In both corn and soybean plots where food was not available, females which were well-fed prior to release parasitized more hosts than unfed females. Well-fed females spent more time hovering and less time searching undamaged leaves than did unfed females. Because hovering time is an indicator of active host searching, the better parasitization rate by well-fed females can be explained by the greater proportion of time spent in active host …

All Peer-Reviewed Publications

Extracts of the root bark of Turraea floribunda have yielded four new limonoids of the havanensin class: 28-nor-4α-carbomethoxy-11β-acetoxy-12α-(2-methylbutanoyloxy)-14,15-deoxyhavanensin-1,7-diacetate; 28-nor-4α-carbomethoxy-11β-hydroxy-12α-(2-methylbutanoyloxy)-14,15-deoxyhavanensin-1,7-diacetate; 18-nor-4α-carbomethoxy-11β-acetoxy-12α-(2-methylbutanoyloxy)-14,15-deoxyhavanensin-1-acetate; and 28-nor-4α-carbomethoxy-7-deoxy-7-oxo-11β-acetoxy-12α-(2-methylbutanoyloxy)-14,15-deoxyhavanensin-1-acetate. The structures were determined by spectroscopic methods. The structure for the first of these compounds was also confirmed by X-ray diffraction methods. © 1995.

Semiochemicals From Froth Of Egg Pods Attract Ovipositing Female Schistocerca Gregaria, R. K. Saini, M. M. Rai, A. Hassanali, J. Wawiye, H. Odongo Jan 1995

Semiochemicals From Froth Of Egg Pods Attract Ovipositing Female Schistocerca Gregaria, R. K. Saini, M. M. Rai, A. Hassanali, J. Wawiye, H. Odongo

All Peer-Reviewed Publications

A chemical signal, originating from the froth of egg pods attracts gravid female Schistocerca gregaria (Orthoptera: Acrididae) to common egg laying sites. Behavioural experiments indicated that females preferred to oviposit in moist sand contaminated with froth (60% egg laying vs 34% in sterilized sand). Extracts and volatiles collected from froth were also attractive to gravid females. In fact, froth volatiles elicited the strongest egg laying response (80% egg laying). Results with froth extracts obtained by sequential extraction with solvents of increasing polarity suggest that both non-polar and polar compounds are involved in the attraction of gravid females. Electroantennogram recordings with …

Optimization Of The In Vitro Feeding Of Rhipicephalus Appendiculatus Nymphae For The Transmission Of Theileria Parva, S. M. Waladde, S. N. Mwaura, G. N. Njihia, F. N. Mwakima

All Peer-Reviewed Publications

An apparatus for artificial feeding of Rhipicephalus appendiculatus nymphae was modified to improve feeding performance. Heparinized blood was supplied above a treated artificial membrane while the ticks attached below on its undersurface. The feeding apparatus was incubated at 37 °C in an atmosphere of 3% CO2 concentration and a relative humidity of 75–80 °0. Under these conditions, 91 °0 of the engorged nymphae attained a mean weight of 6–11 mg, and an average of 93 °0 of those nymphae moulted into adults. When this system was used to feed nymphal ticks on blood infected with Theileria parva piroplasms, the mean …

Lipophorin And Apolipophorin-Iii In Solitary And Gregarious Phases Of Schistocerca Gregaria, Dorington O. Ogoyi, Ellie O. Osir, Norah K. Olembo Jan 1995

Lipophorin And Apolipophorin-Iii In Solitary And Gregarious Phases Of Schistocerca Gregaria, Dorington O. Ogoyi, Ellie O. Osir, Norah K. Olembo

All Peer-Reviewed Publications

Lipophorin was isolated from the hemolymph by KBr density gradient ultracentrifugation. Apolipophorin-III (apoLp-III) was isolated from low-density lipophorin (LDLp). High-density lipophorin (HDLp) (Mr ∼-620,000) consisted of two apoproteins, apoLp-I (Mr ∼-224,000) and apoLp-II (Mr ∼-81,000). Isolated apoLp-III (Mr ∼-20,000) had two isoforms in non-denaturing gels. Injection of adipokinetic hormone-I resulted in the formation of LDLp in both locust phases. Lipid content of HDLp was estimated at 48.4% and 51.8% for solitary and gregarious locusts, respectively. In LDLp, lipids constituted 59.8% and 57.1% for gregarious and solitary locusts, respectively. The results suggest that the gregarious locusts were more efficient in the …

Effect Of Pubescence In Cowpea Resistance To The Legume Pod Borer Maruca Testulalis (Lepidoptera: Pyralidae), S. Oghiakhe Jan 1995

Effect Of Pubescence In Cowpea Resistance To The Legume Pod Borer Maruca Testulalis (Lepidoptera: Pyralidae), S. Oghiakhe

All Peer-Reviewed Publications

Pubescence (trichomes) in wild and cultivated cowpeas, Vigna vexillata and V. unguiculata, adversely affected oviposition, mobility, and food consumption and utilisation by the legume pod borer, Maruca testulalis (Geyer), in tests conducted with TVnu 72 (wild, highly resistant and highly pubescent), TVu 946 (semi-wild, moderately resistant and pubescent) and IT82D-716 (cultivated, highly susceptible and pubescent). In free-choice and no-choice tests, significantly (P < 0.05) fewer eggs were laid on 3-week-old potted plants of TVnu 72, the highly pubescent and wild species; this species also received fewer eggs on abaxial and adaxial leaf surfaces. Ovipositional activity on stipules, stem, branches, terminal shoots, adaxial and abaxial leaf surfaces of the susceptible cultivar, IT82D-716 was higher (P < 0.05) than on TVu 946 and TVnu 72. More eggs were laid on the abaxial surfaces than on the adaxial surfaces of leaves for all tests conducted, except for the TVnu 72 no-choice test. Significant negative correlations (r = -0.99** and r = -0.99**) were found between mean number of eggs laid and length and density of non-glandular trichomes. There was a significant negative correlation (r = -0.99**) between larval velocity and length of non-glandular trichomes on pod surface. Similarly, significant negative correlations (r = -0.85* and -0.89*) were found between larval velocity and density and length of non-glandular trichomes on leaf surface. Pods of IT82D-716 and TVnu 72 were the most - and least - preferred for settling by larvae of M. testulalis, respectively. There was a significant positive correlation (r = 0.99**) between larval penetration time on pods and length of non-glandular trichomes. Weight loss, number of feeding punctures and number of larvae on whole pods of TVnu 72 were lower and significantly different (P < 0.05) from IT82D-716 and TVu 946. This study showed that it would be advantageous to use TVnu 72 in a breeding programme to incorporate pubescence into high-yielding commercial cultivars for resistance against M. testulalis and possibly other major pests. © 1995.

Determination Of Selenium In Food Supplements By Differential-Pulse Cathodic Stripping Voltammetry In The Presence Of Added Copper, Walter Holak, John Specchio Dec 1994

Determination Of Selenium In Food Supplements By Differential-Pulse Cathodic Stripping Voltammetry In The Presence Of Added Copper, Walter Holak, John Specchio

Department of Nutrition and Food Studies Scholarship and Creative Works

Selenium was determined by cathodic stripping voltammetry in a 1 mol l -1 HCl acid solution containing added CuII. In this medium, selenium was preconcentrated on the hanging mercury drop electrode and stripped cathodically in differential-pulse mode. After a deposition period of 1 min, 0.2 ng ml-1 of selenium could be detected. The method was applied to the analysis of food supplements. Total selenium was determined after digestion of the sample with HNO3 - HClO4 and reduction to the electroactive SeIV by heating with HCl. Inorganic selenium (i.e., selenite and selenate) was similarly determined after extraction with dilute sodium hydroxide …

Summary Results Of A Survey Of Economic Development In Texas Cities (Report 95-1), Delbert A. Taebel Nov 1994

Summary Results Of A Survey Of Economic Development In Texas Cities (Report 95-1), Delbert A. Taebel

Center for Economic Development Research and Service Publications - Archive

Economic development is the new kid on the block in city government. If one looks at any textbook on municipal administration published more than 10 years ago, economic development as a city function would not even have been mentioned. Yet, because of the dozens of conferences and flurry of articles focusing on economic development, it may seem to many that economic development has been around for a long time. Indeed, seven years ago the Institute of Urban Studies published an initial study entitled "Local Economic Development in Texas." Since then, of course, economic development has become a permanent program in …

Religious Imagery And The American Association For Adult Education: The Gospel Of The Aaae, Frederick Milacci Oct 1994

Religious Imagery And The American Association For Adult Education: The Gospel Of The Aaae, Frederick Milacci

Faculty Publications and Presentations

Using the findings from an analysis of articles appearing in the Journal of Adult Education, this paper shows how early adult educators used religious imagery to express their fervor and enthusiasm for the field of adult education. This religious-like sense of mission and purpose among early leaders in the field was grounded in the belief that adult education could bring hope and help to a troubled world and provides a refreshing alternative to the present-day push towards professionalization.

Urban Microclimates And Growth Of Sweetgum Street Trees, Roger Kjelgren, James R. Clark Oct 1994

Urban Microclimates And Growth Of Sweetgum Street Trees, Roger Kjelgren, James R. Clark

Plants, Soils, and Climate Faculty Publications

Microclimates characteristic of urban park, plaza, and canyon spaces were related to physiology and growth of even-aged sweetgum (Liquidambar styraciflua L.) street trees. Microclimates, tree growth, and physiological responses were characterized diurnally and seasonally. Park and plaza sites received unobstructed sunlight while the canyon was limited to four hours of direct solar radiation in midsummer. Potential seasonal insolation was 44 per cent of the potential maximum at the canyon and over 90 per cent at the park. Heating from paved surfaces at the plaza resulted in cumulative pan evaporation nearly 50 per cent greater than the other sites. Tree growth …

Proximity Of Release Points Of Pheromone Components As A Factor Confusing Males Of The Spotted Stem Borer, Chilo Partellus, Approaching The Trap, Slawomir A. Lux, Ahmed Hassanali, Wilber Lwande, Florence N. Njogu Aug 1994

Proximity Of Release Points Of Pheromone Components As A Factor Confusing Males Of The Spotted Stem Borer, Chilo Partellus, Approaching The Trap, Slawomir A. Lux, Ahmed Hassanali, Wilber Lwande, Florence N. Njogu

All Peer-Reviewed Publications

The effect of proximity of the release points of the two pheromone components (Z)-11-hexadecenal and (Z)-11-hexadecen-1-ol of the spotted stem borer, Chilo partellus (Lepidoptera: Pyralidae) on behavior of the males and on trapping efficiency was investigated. Separating the dispensers of the two components in the trap by a mere 3 cm resulted in a threefold decrease in trap performance, compared to very close release of the components. The result is attributed to possible distortion of the pheromone signal, resulting in confused behavior of C. partellus males in the vicinity of the trap. The ethological and practical implications of the phenomenon …

All Peer-Reviewed Publications

Olfactometric bioassays showed that nymphs of crowded desert locusts, Schistocerca gregaria, aggregated in response to volatiles derived from their feces and to volatiles emitted from the feces of young adults, but were indifferent to volatiles emitted by older adult feces. On the other hand, young and older adults were not only responsive to their own fecal volatiles but also cross-responsive to each other's and that of the nymphs. Charcoal-trapped volatiles from the feces and synthetic blends of the fecal volatiles also elicited similar responses. Young adults responded moderately to a blend of nymphal volatiles and those derived from nymphal feces. …

Growth And Water Relations Of Kentucky Coffee Tree In Protective Shelters During Establishment, Roger Kjelgren Jul 1994

Growth And Water Relations Of Kentucky Coffee Tree In Protective Shelters During Establishment, Roger Kjelgren

Plants, Soils, and Climate Faculty Publications

Growth and water relations of Kentucky coffee tree [Gymnocladus dioica (L.) K. Koch] whips in translucent tubelike shelters were investigated. In a container study, 1.2-m-high shelters were placed over whips following transplanting, then diurnal microclimate, water relations, and water use were measured. Shelter air temperature and vapor pressure were substantially higher, and solar radiation was 70% lower, than ambient conditions. Sheltered trees responded with nearly three-times higher stomatrd conductance than nonsheltered trees. However, due to substantially lower boundary layer conductance created by the shelter, normalized water use was 40910 lower. In a second experiment, same-sized shelters were placed on whips …

Inter-Relations Of Solvable Potentials, Asim Gangopadhyaya, Prasanta K. Panigrahi, Uday P. Sukhatne

Physics: Faculty Publications and Other Works

Solvable Natanzon potentials in nonrelativistic quantum mechanics are known to group into two disjoint classes depending on whether the Schrödinger equation can be reduced to a hypergeometric or a confluent hypergeometric equation. All the potentials within each class are connected via point canonical transformations. We establish a connection between the two classes with appropriate limiting procedures and redefinition of parameters, thereby inter-relating all known solvable potentials.

What We Know About Acquisition Of Adult Literacy: Is There Hope?, Helen Abadzi

Curriculum and Instruction Faculty Publications - Archive

Literacy acquired in childhood positively influences quality of life, but the effects of literacy acquired in adulthood are not well known. Experience shows that literacy is not easily disseminated to adults and that the skills of neoliterates are not stable. Dropouts, mastery, and retention rates are about 50 percent at each stage, so the effectiveness rate of some projects may only be 12 to 15 percent. As a result, literacy projects are now rarely funded by the World Bank despite requests from governments. To find causes for the low effectiveness of programs, two literature reviews were conducted on the topic …

Natural Attraction Of Livestock Ticks By The Leaves Of A Shrub, S. M. Hassan, O. O. Dipeolu, M. M. Malonza Jun 1994

Natural Attraction Of Livestock Ticks By The Leaves Of A Shrub, S. M. Hassan, O. O. Dipeolu, M. M. Malonza

All Peer-Reviewed Publications

During examination of leaves of different plants on Rusinga Island, Kenya, ticks were commonly found on the leaves of a plant identified as Acalypha fruticosa Forsk. var. villosa Hutch (Euphorbiaceae). Larvae of Rhipicephalus appendiculatus were the predominant ticks encountered, found quiescent on the undersurface of the leaves. Laboratory investigations showed that significant numbers of ticks were attracted by odours from this plant. It was concluded that the leaves of A. fruticosa are attractive to this tick and have potential for use as a trap to control ticks. © 1994 Centre for Tropical Veterinary Medicine.
