Curriculum-Oriented Cai Based On Instructional Technology To Be Used For Teaching Secondary School Students Introductory Library Skills, Theresa K. Toohil

CCAC Theses and Dissertations

In 1990, the New York State Education Department presented a syllabus that required the teaching of curriculum-oriented library skills and suggested the use of computers to be integrated with the teaching of these skills whenever possible. Schools in New York State are now trying to implement the suggestions in the syllabus. Many authors of educational articles have written at length concerning the incorporation of computer-assisted instruction (CAl) into the classroom, but clear directions have not been provided in the literature for the design or implementation of the necessary software.

The purpose of this study was to design a program based …

Dissertation Report Is 8995 Using Dialog Cip At Winona State University To Educate End-Users, Kathryn Sullivan

CCAC Theses and Dissertations

Graduate students need to know the resources of their university library in order to do research and cannot be expected to remember any library training they may have received as undergraduates. A class offered by the library on how to search databases available through DIALOG's Classroom Instruction Program (CIP) was proposed, in cooperation with existing research classes in the student's field. A study was conducted at Winona State University. Winona, MN, with research classes offered by two professors in the field of special education. The study was to determine whether the information presented in an instruction session based on six …

On A Unique Tree Representation For P4-Extendible Graphs, B. Jamison, S. Olariu

Computer Science Faculty Publications

Several practical applications in computer science and computational linguistics suggest the study of graphs that are unlikely to have more than a few induced paths of length three. These applications have motivated the notion of a cograph, defined by the very strong restriction that no vertex may belong to an induced path of length three. The class of P₄-extendible graphs that we introduce in this paper relaxes this restriction, and in fact properly contains the class of cographs, while still featuring the remarkable property of admitting a unique tree representation. Just as in the case of cographs, the …

Intelligent Structural Operators For The K-Way Graph Partitioning Problem, Gregor Von Laszewski

Northeast Parallel Architecture Center

A parallel genetic algorithm for the graph partitioning problem is presented, which combines general heuristic algorithms with techniques that are described in evolution theory. In the parallel genetic algorithm the selection of a mate is restricted to a local neighborhood. In addition, the parallel genetic algorithm executes an adaptation step after an individual is generated, with the genetic operators crossover and mutation. During the adaptation step the solution is improved by a common algorithm. Another selection step decides if the adapted descendant should replace the parent individual. Instead of using a uniform crossover operator a more intelligent crossover operator, which …

An Analysis Of The Monitored Electronic Alarm Activations In The Perth Metropolitan Area, Lynnette M. Bloom, James M. Cross, David Mcdougall

Research outputs pre 2011

This study as indicated in [7] was carried out under the auspices of Edith Cowan University's Institute of Security and Applied Technology and had the support of the Western Australian Police and the Perth-based Central Monitoring Agencies. The data analysed was obtained essentially from Police records, backed up by data from two of Perth's larger security companies, and consists of all the monitored alarms in the Perth Metropolitan Area which were attended by the police in the months of May and September 1989.In our consideration of the frequency of alarms by time of day and day of week, and the …

On Separable Torsion- Free Modules Of Countable Density Character, R. Gobel, Brendan Goldsmith

Articles

The endomorphism algebras of modules of large cardinalities have been extensively studied in recent years using the combinatorial set-theoretic techniques of Shelah-the so-called black-box methods (see, e.g., [4, 5, 151). Despite the spectacular success of these methods, they are not suitable for realization theorems at small carinalities. Of course at the level of countability (or rather more generally for cardinals ~2’~) there are in some cases the original dramatic results of A. L. S. Corner [ 1, 2, 31 and the more recent generalizations of Gobel and May [ 111. Very recently the study of realization problems at cardinalities

Ab Initio Study Of The Intermolecular Potential Of Ar–H2o, G. Chalasinski, M. M. Szczesniak, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The combination of supermolecular Møller–Plesset treatment with the perturbation theory of intermolecular forces is applied in the analysis of the potential‐energy surface of Ar–H₂O. The surface is very isotropic with the lowest barrier for rotation of ∼35 cm⁻¹ above the absolute minimum. The lower bound for D_e is found to be 108 cm⁻¹ and the complex reveals a very floppy structure, with Ar moving freely from the H‐bridged structure to the coplanar and almost perpendicular arrangement of the C₂ –water axis and the Ar–O axis, ‘‘T‐shaped’’ structure. This motion is almost isoenergetic (energy change …

Analysis And Finite Element Approximation Of Optimal Control Problems For The Stationary Navier-Stokes Equations With Dirichlet Controls, M. D. Gunzburger, L. S. Hou, Tom Svobodny

Mathematics and Statistics Faculty Publications

Optimal control problems for the stationary Navier-Stokes equations are examined from analytical and numerical points of view. The controls considered are of Dirichlet type, that is, control is effected through the velocity field on (or the mass flux through) the boundary; the functionals minimized are either the viscous dissipation or the L4-distance of candidate flows to some desired flow. We show that optimal solutions exist and justify the use of Lagrange multiplier techniques to derive a system of partial differential equations from which optimal solutions may be deduced. We study the regularity of solutions of this system. The n, finite …

Optimal Processor Assignment For Pipeline Computations, David Nicol, Rahul Simha, Alok N. Choudhury, Bhagirath Narahari

Electrical Engineering and Computer Science - All Scholarship

The availability of large-scale multitasked parallel architectures introduces the following processor assignment problem for pipelined computations. Given a set of tasks and their precedence constraints, along with their experimentally determined individual response times for different processor sizes, find an assignment of processors to tasks. Two objectives interest us: minimal response given a throughput requirement, and maximal throughput given a response time requirement. These assignment problems differ considerably from the classical mapping problem in which several tasks share a processor; instead, we assume that a large number of processors are to be assigned to a relatively small number of tasks. In …

Groundwater Hydrology Of A Population Of Lindera Melissifolia In Arkansas, J. Dainette Priest, Robert D. Wright

Journal of the Arkansas Academy of Science

Groundwater hydrology was monitored from October through August in and around a bottomland forest pond containing Lindera melissifolia, pondberry. The study site exhibited a series of low ancient dunes and depressions, with seasonal ponds in the depressions. Ponds showed no surface inlets or outlets. Shallow wells were made and soil cores removed along a transect from the top of one dune across the pond to a lower dune. Piezometers were installed in the wells and groundwater levels monitored. Soil core samples were analyzed to determine particle size distribution at soil profile positions selected during field analysis. It was shown that …

Preparation Of A Series Of N-Phenylamides Of 5-Bromo-6-Chloronicontinic Acid And 5-Bromo-2-Chloronicontinic Acid, Frank L. Setliff, Jody Z. Caldwell

Journal of the Arkansas Academy of Science

A series of N-phenylamides of 5-bromo 6-chloronicotinic acid and 5-bromo-2-chloronicotinic acid were synthesized by treatment of their freshly prepared acid chlorides with the appropriately ring substituted anilines. Thirty new compounds were prepared, and their structures were ascertained by elemental analyses and spectroscopic techniques. Spectroscopic trends in the infrared spectra of the two series were examined in an attempt to correlate structural and electronic effects to hydrogen bonding tendencies.

A Visualization Model For Massively Parallel Algorithms, Rashi Khanna, Bruce M. Mcmillin

Computer Science Faculty Research & Creative Works

A visualization model has been developed to analyze the performance of a massively parallel algorithm. Most visualization tools that have been developed so far for performance analysis are based generally on individual processor information and communication patterns. These tools, however, are inadequate for massively parallel computations. It is difficult to comprehend the visual information for many processors. The model, SMILI (Scientific visualization in Multicomputing for Interpretation of Large amounts of Information), addresses this problem by using abstract representations to attain a composite picture which gives better insight to the behavior of the algorithm. Chernoff s Faces have been selected to …

Minimax-Optimal Stop Rules And Distributions In Secretary Problems, Theodore P. Hill, Ulrich Krengel

Research Scholars in Residence

For the secretary (or best-choice) problem with an unknown number N of objects, minimax-optimal stop rules and (worst-case) distributions are derived, under the assumption that $N$ is a random variable with unknown distribution, but known upper bound n. Asymptotically, the probability of selecting the best object in this situation is of order of (log n)^-1. For example, even if the only information available is that there are somewhere between 1 and 100 objects, there is still a strategy which will select the best item about one time in five.

Predictive Probabilities In Employee Drug-Testing, John M. Gleason, Darold T. Barnum

RISK: Health, Safety & Environment (1990-2002)

Substance abuse in the U.S. has been estimated to cost $99 billion annually through lower productivity. Yet the authors urge caution in attempting to reduce these costs and health and safety Risks. In doing so, they cite commonly high frequencies of false negatives and false positives in employee drug tests - the latter having the potential to do great injustice to many drug-free employees.

The Problem Of Mutual Exclusion: A New Distributed Solution, Rajeev Chawla

Theses and Dissertations

In both centralized and distributed systems, processes cooperate and compete with each other to access the system resources. Some of these resources must be used exclusively. It is then required that only one process access the shared resource at a given time. This is referred to as the problem of mutual exclusion. Several synchronization mechanisms have been proposed to solve this problem. In this thesis, an effort has been made to compile most of the existing mutual exclusion solutions for both shared memory and message-passing based systems. A new distributed algorithm, which uses a dynamic information structure, is presented to …

The Gulf Of California As A Large Marine Ecosystem, Patricia A. Morrissey

Marine Affairs Theses and Major Papers

Large marine regions characterized by unique bathymetry, hydrography and productivity, within which marine populations have adapted reproductive, growth, and feeding strategies constitute large marine ecosystems (LME) (Sherman and Alexander, 1986). The Gulf of California a semi-enclosed sea off the western coast of Mexico qualifies as a LME as it presents physical and biological characteristics not found in the adjoining Pacific. This area sustains the largest commercial fishery in the country which is the sardine fishery. the sardine population resident in the Gulf of California has coupled its reproductive and migration strategies to the environment of this region. Fluctuations of the …

Impacts Of The Unclos Iii Consent Regime On U. S. Marine Scientific Research, 1982-1989, Matthew Patrick Murphy

Marine Affairs Theses and Major Papers

The 1982 Conference on the Law of the Sea (UNCLOS III) has given states jurisdiction over unprecedented scopes of ocean space. Marine scientific research is among the activities under coastal state control. This thesis examines five possible areas of impact of coastal state control on United States research programs. These are: 1. research which was denied outright, 2. reasons for denials, 3. research which was delayed, 4. the extent to which researchers avoid requests in the waters of restrictive states, and 5. the level of interest among UNOLS institutions in cooperative arrangements with foreign governments. The international legal framework for …

Alyeska, Sullom Voe And The Oil Pollution Act Of 1990: A Comparison Of Tanker Safety Regulation And Environmental Monitoring, Neil V. Kelly

Marine Affairs Theses and Major Papers

The Exxon Valdez oil spill in 1989 highlighted deficiencies in the Trans Alaska Pipeline System's (TAPS) marine operation on both regulatory and operational levels. The United States Congress passed the Oil Pollution Act of 1990 to promote the prevention of oil spills and to improve our ability to mitigate the effects of spills that occur. An oil terminal roughly analogous to the TAPS terminal at Valdez, Alaska, exists at Sullom Voe in the Shetland Islands, west of Norway and to the north of Scotland in the North Sea. The Sullom Voe terminal has had an environmental advisory group guiding policy …

Striped Bass Management In Rhode Island, Thomas N. Fetherston Ii

Marine Affairs Theses and Major Papers

The management of highly migratory marine species is a difficult and complex task. No creature better represents the myriad problems faced by those attempting interstate fisheries management than the striped bass of the Atlantic coast. Their high stock levels in the late 1960s attracted unprecedented attention from commercial and sport fishermen alike. The dramatic crash of these stocks in the late 1970s, subsequent attempts at coastwide management, eventual Federal intervention and finally the rebound of the Atlantic striped bass population is an interesting case study. This paper will focus on what transpired in the State of Rhode Island during this …

The Impact Of Tourism On Block Island, Thomas Green

Marine Affairs Theses and Major Papers

This thesis examines the impacts of tourism on the residents of Block Island. More specifically the study seeks to identify the specific areas of concern, as perceived by the residents, in three major areas of impact: economic, social and environmental. It was hypothesized that the residents of Block Island, a mature tourist destination area, had formulated perceptions of the impacts of tourism and that these perceptions, if analyzed, would identify protection of the environment and threats to the Island's lifestyle as major concerns. Factor analysis was employed to analyze survey responses from residents on questions regarding tourism on Block Island. …

The Siia: A Mechanism For Addressing Pollution Problems Plaguing New Jersey's Coastal Zone, Laurie J. Sands

Marine Affairs Theses and Major Papers

New Jersey has been plagued in recent years by beach closures resulting from elevated bacteria levels after rainfall events. The Sewage Infrastructure Improvement Act (SIIA) was adopted to correct these problems by addressing both point and nonpoint sources of pollution found in discharges of stormwater. However, there are problems with the SIIA such as overly burdensome requirements, limited resources and lack of future funding and direction. This research identifies these problems and examines existing State and federal legislation to find the necessary components to correct these concerns. The results show that by pursuing a legislative amendment to the SIIA, redistributing …

International Journal of Speleology

Data on the age structure, fecundity, egg morphology and feeding habits of the Spelaeiacris tabulae population from Wynberg cave are reported and compared with other Rhaphidophoridae species. S. tabulae shows a certain degree of adaptation to cave life, as usual in the other temperate species of Rhaphidophoridae.

Integration Of Abductive And Deductive Inference Diagnosis Model And Its Application In Intelligent Tutoring System, Jingying Zhang

Computer Science Theses & Dissertations

This dissertation presents a diagnosis model, Integration of Abductive and Deductive Inference diagnosis model (IADI), in the light of the cognitive processes of human diagnosticians. In contrast with other diagnosis models, that are based on enumerating, tracking and classifying approaches, the IADI diagnosis model relies on different inferences to solve the diagnosis problems. Studies on a human diagnosticians' process show that a diagnosis process actually is a hypothesizing process followed by a verification process. The IADI diagnosis model integrates abduction and deduction to simulate these processes. The abductive inference captures the plausible features of this hypothesizing process while the deductive …

On The Normalized Yield (Events/Rad/Dalton) Of Biological Molecules Irradiated With Energetic Heavy Ions, Robert Katz

Robert Katz Publications

When irradiated with electrons or γ-rays, a number of biological molecules display an approximately linear relationship between the reciprocal of the D₃₇ dose and molecular weight. This is conventionally plotted as a relation between target molecular weight and true molecular weight, where the target molecular weight M_t is given as: M_t × (D₃₇) = α (1) where α is approximately 10¹⁰ Da-rad/eV of the energy assumed to be “deposited in the target” in a single “hit” for expression of the end-point. We emphasize that D₃₇ is expressed in rads for we will later …

Radial Distribution Of Dose, Robert Katz, Matesh N. Varma

Robert Katz Publications

The radial distribution of dose about the path of a heavy ion, principally from delta rays, is one of the central contributions of atomic physics to the systematization of high LET radiation effects in condensed matter, whether the detection arises in chemical, physical, or biological systems. In addition to the radial distribution of dose, we require knowledge of the response of the system to X-rays or gamma-rays or to beams of energetic electrons such that the electron slowing-down spectra from these radiations can approximate the slowing-down spectra from delta rays even at different radial distances from the ion's path. A …

Additional Fossil Evidence On The Differentiation Of The Earliest Euprimates, Kenneth D. Rose, Thomas M. Bown

United States Geological Survey: Staff Publications

Several well-preserved jaws of the rare North American omomyid primate Steinius vespertinus, including the first known antemolar dentitions, have been discovered in 1989 and 1990 in the early Eocene Willwood Formation of the Bighorn Basin, Wyoming. They indicate that its dental formula is as primitive as those in early Eocene Donrussellia (Adapidae) and Teilhardina (Omomyidae) - widely considered to be the most primitive known euprimates - and that in various dental characters Steinius is as primitive or more so than Teilhardina. Therefore, despite its occurrence at least 2 million years later than Teilhardina, S. vespertinus is the …
