Nutrient Relations Of Some Northern Minnesota Forest Communities, Richard H. Bares

Theses and Dissertations

Quantitative information on chemical and physical properties of soils under aspen and jack pine and chemical properties of peat and water under black spruce and tamarack, is limited. The present study quantifies soil particle size, electrical conductivity (E.C.), water soluble and replaceable calcium (Ca) , magnesium (Mg), potassium (K), sodium (Na) , manganese (Mn) and strontium (Sr) concentrations in soils under aspen and jack pine communities. Aspen was found on alkaline clay soils with high Ca and Mg concentrations, and jack pine grew on wel1-drained, acidic, sandy clay loams high in Mn. Organic soils under peat and tamarack were analyzed …

On The Dutch Expletive And Related Syntactic Problems, Kornelis J. Boot

Theses and Dissertations

In his Über das niederländische Adverbialpronomen 'er' Bech argues that the subject expletive of Dutch is inserted when the NP subject has an indefinite article. Bech also claims that the subjective expletive is a local subject and not a logical subject.

This thesis proposes that the use of the subject expletive cannot be based upon a traditional structuralist concept. The author rejects some of Bech's claims and argues for a semantic distinction between definiteness and non-definiteness as a basis for expletive insertion. An attempt is also made to apply the same distinction in accounting for the use of het with …

States' Rights And Dualism: An Administrative Study Of Andrew Jackson's Indian Policy, John N. Olsgaard

Theses and Dissertations

This study attempts to provide the tools necessary for an accurate formulation of Andrew Jackson's administrative policies regarding the removal of the Five Civilized Tribes to the west of the Mississippi River. Such an undertaking integrates the biographical material available on Jackson with the narrative data compiled on the removal of the tribes, in a manner that will promote better understanding of the justifications, politics, and personal biases of the individuals involved.

This paper challenges the predominant view that Jackson was guided by an ideological affinity for states' rights philosophy in his presidential relations with the Indians. Jackson was not …

The Effects Of A Physical Conditioning Program On Selected Measures Of Self Concept, Kirby Franz Weise

Theses and Dissertations

Thirty-nine female college students participated in a class designed to increase their muscle strength and cardiovascular fitness. Changes were monitored on thirteen physical variables and eleven self concept variables. Nineteen females acted as a "control group," to test whether just the decision to change one's physical fitness affects self concept. They were measured on four self concept variables eight weeks prior to as well as at the beginning and end of their eight-week conditioning course.

During the sixteen week semester the experimental females, as a group, improved significantly on ten of the thirteen physical variables and nine of the eleven …

An Analysis Of The Piscine Parasitofauna Of Four North Dakota Streams, Daniel R. Sutherland

Theses and Dissertations

Analyses of the fish, parasites and water of four North Dakota rivers in the Missouri River and Hudson Ba.y drainages were made. A total of 277 fish representing 13 families was. collected from June 28 through November 2, 1975 from 19 sampling stations on the Missouri River below Garrison Dam, the James River above Jamestown Reservoir, the Sheyenne River above Lake Ashtabula and the entire Wild Rice River. The abiotic factors of water temperature, dissolved oxygen, chlorides, nitrates, nitrites, sulphates, orthophosphates, pH and turbidity were determined for each sampling station using Standard Methods or Hach procedures. Of the fish examined …

The Attribution Of Fault To Rape Victims: Subject Variables Affecting Blaming, Stephan Podrygula

Theses and Dissertations

This study investigates the subject variables involved in the attribution of fault to rape victims. A consideration of attribution theory, in particular Heider's "naive analysis of action," suggests that innocent victims of misfortune will be blamed, however implausible this at first seems. Heider's theory has led to two specific theoretical explanations for blaming, E. Walster's defensiveness hypothesis and Lerner's just world hypothesis, both of which are examined in some detail. The relevant theoretical and experimental literature is reviewed, an assessment of the current standing of these explanations is made, and unresolved issues are raised. Several issues and questions based on …

The Effects Of Ultrasonic Vibration, Tension And Torsion On The Charge Acceptance Of The Alkaline Silver Electrode ; Ii. Potentiostatic Studies Of The Oxide Growth Rate Law For The Alkaline Silver Electrode ; Iii. The Determination Of Ionic Transport In Silver Oxide Using Radiotracer Techniques With Ag[Superscript 110m], Reed Harold Chase

Theses and Dissertations

The effect of ultrasonic vibration on the anodic oxidation of silver foil in KOH was studied. An increase in charging capacity of approximately 20% was found to be the result of cavitation erosion. Silver wire was exposed to tension and torsion during oxidation but no change in charge acceptance was caused by these stresses. The oxide growth rate on silver foil electrodes was compared to rate equations that have been proposed for other metals. Uhlig's equations for the growth of semiconductor oxides was found to describe most of the data. The data did not fit other rate equations. Determination of …

The Supreme Court, Philosophy And Freedom Of Choice: An Analysis, Walter N. Blevins

Theses and Dissertations

It is a major contention of this thesis that to argue, debate and philosophize about choice and freedom of choice is one thing, but arguments as to the existence of free choice and claims to its exercise do not mean much, unless within the framework of social and political life the freedom is recognized and protected by some legal authority— in this case, the United States Supreme Court.

This thesis is directed at two areas of political research. First will be a survey and examination of current philosophic literature in order to specify and describe the various models employed in …

Processing Pictorial Information: Effects Of Informativeness, Location, And Duration, Richard L. Metzger

Theses and Dissertations

When an observer views a picture, enough information processing occurs prior to the first eye movement to direct the eyes to an informative portion of the picture. This early processing is influenced by the overall coherency of the picture and the informativeness of the various sections of the picture. The present study tested the hypothesis that the processing of pictorial information proceeds in a hierarchical manner from the most informative sections of a picture to the least informative sections. The hypothesis was evaluated by observing changes in the recognition accuracy of high medium and low informative sections of a picture, …

Frontier In Transition: A Demographic History Of Benton Country, Minnesota, 1850-1870, Stephen J. Schilling

Theses and Dissertations

The purpose of this thesis is to examine closely the transformation of a frontier area into a settled community. The demographic history of Benton County, Minnesota, from 1850 to 1870, is examined in detail. The major emphasis is on the structure of the population and its changes over a twenty-year period. The central goal is to determine if there was a pattern to these chanoes. Generalizations applied to the entire frontier will then be compared to this one county to see if they are valid.

The manuscript census was the major source of information. The demographic information for each individual, …

Effect Of Altitude On The Peripheral Degradation Of Thyroxine In The Uinta Ground Squirrel (Citellus Armatus), Stuart K. Ware

Theses and Dissertations

Various methods were employed to detect changes in the peripheral degradation of thyroxine (T4) in adult Uinta ground squirrels (Citellus armatus) collected at two different altitudes (5400 and 9000 feet.) Plasma half-life of injected T4-125I (tl/2) was significantly decreased with altitude, as was T4-125I distribution space (TDS) and T4 degradation and secretion rate (TSR). In vitro deiodination of T4-125I by heart homogenates was not affected, while urinary excretion of thyroxine derived iodide was increased at high altitude 44-70 hours post-injection. Both total and free serum T4 concentrations were reduced at high altitude, although not significantly. The cause of the reduced …

Potential Diets For Carp Production, Rex Carlton Infanger

Theses and Dissertations

The objective of this study was to determine the feasibility of raising carp on pig manure and coli, Brassica campestris. The use of pig feces as a source of fish food has been questioned by researchers (Hickling 1968). Coli was selected for dietary intake by fish since it is used for human consumption by the Indians of Guatemala. Commercial fish food (Silver Cup) was used for a control diet. These diets were both combined and used as a single source of food.

Spatial And Temporal Partitioning Between Sympatric Rodents: Zapus And Peromyscus, Emma Bernice Speer

Theses and Dissertations

Partitioning space and time by seemingly sympatric rodents, Zapus princeps and Peromyscus maniculatus, were examined as possible mechanisms allowing coexistence. The two populations were studied in Central Utah with an electrically monitored grid. Spatial separation of individuals and the populations minimized confrontations and created local allopatric distribtuions. Temporal partitioning was not used as a mechanism to allow coexistence and was apparently independent of spatial partitioning. The Peromyscus population was composed primarily of males which may have been due to less favorable habitat and/or presence of Zapus. The data show that Peromyscus tend to avoid Zapus, possibly due to deleterious aggressive …

Voltammetric And Electrochemical Kinetic Studies Of The Halides And Halogens At A Platinum Rotating Ring-Disk Electrode In Anhydrous Acetic Acid, Donald Harrison Cranney

Theses and Dissertations

The electrochemical behavior of the iodine-iodide couple was investigated in both basic and neutral acetic acid solutions at a platinum rotating ring-disk electrode. Voltammetric curves were obtained and discussed. Various kinetic parameters were determined and by comparing to theoretical kinetic parameters a probable reaction mechanism was deduced. The mechanism that best fit experimental results is the following I- + S = I(S) + e- I(S) + I- = I2 + S + e (slow). The electrochemical behavior of bromine, bromide, and chloride was also investigated in the same media. Voltammetric curves were recorded and discussed with emphasis on the hysteresis …

Sensitivity Of Process Variables On Rigid Polyurethane Foaming, Bruce A. Pugsley

Theses and Dissertations

Inadequate understanding and/or control of the polyurethane rigid foam process normally requires five to ten percent overpack of cavities to obtain correct fill and foam characteristics. This practice of overpacking has resulted in excessive waste and cost.

The Osteology And Myology Of The Head And Neck Region Of Callisaurus, Cophosaurus, Holbrookia, And Uma, The "Sand Lizards", Douglas Charles Cox

Theses and Dissertations

Blainville (1835) wrote the first description of a sand lizard and named it Callisaurus draconoides. Since his time various authors have published articles concerning sand lizards. Girard (1851) described Holbrookia maculata, Trochel (1852) described Cophosaurus texanus, and that same year Baird and Girard synonymized Cophosaurus with Holbrookia providing the name Holbrookia texana, which has stood for over 100 years. Subsequently, Baird (1858) described Uma notata.

Population Characterization And Feeding Behavior Of A Subtidal Neogastropod, Amphissa Columbiana, Bruce C. Stone

Theses and Dissertations

The neogastropod Amphissa columbiana is found abundantly in subtidal areas of the San Juan Archipelago. Two populations studied were composed of distinct age classes of sexually immature and mature specimens. Reproduction appears to take place in the fall by snails at least two years old. Amphissa is a chemoreceptive scavenger that usually feeds on carrion and on dead and injured animals. Feeding behavior is mediated by chemical attractants from dead and traumatized tissue. An unusual feeding association is formed where Amphissa congregate around feeding predators to share their meals. A specific defense mechanism is deployed by Amphissa especially in response …

A Study Of Selected Photo Fries Rearrangements, Elwood Lloyd Loveridge

Theses and Dissertations

The Fries rearrangement of phenyl esters is reviewed and compared to the reaction when light is the source of energy. The products are different due to different mechanism of reaction. Light energy causes either free radical or concerted reactions. The S-phenylthiol esters and anilides were studied also. Although many of the rearrangements are the same, we did not see any alkyl migration nor decarboxylation type reactions with either the sulfur or nitrogen compounds. Three papers have been published from this work: Bradshaw, J. S., Knudsen, R. D. and Loveridge, E. L., J. Org. Chem., 35, 1219 (1970); Bradshaw, J. S., …

The Snowy Egret (Egretta Thula Brewsteri) A Life History Study At Utah Lake With Comments On The Subspecies Status, Gerald Leigh Gunnell

Theses and Dissertations

This study was conducted to augment the limited information available regarding the Snowy Egret in the Utah Lake area of Utah. Field observations included the following: nesting habits; egg and clutch sizes; sexual, defense, and feeding behaviors. Analysis was made of the distinguishing subspecies characteristics (culmen, tarsus, and wing length) of the Snowy Egrets and of the distribution of the birds. Field observations showed that growth measurements of the young varied from 16.75 g at hatching to 260.58 g after 17 days. Culmen and tarsus measurements were 15.41 mm and 14.12 mm to 53.18 mm and 62.18 mm, respectively, after …

Defense Mechanism And Feeding Behavior Of Pteraster Tesselatus Ives (Echinodermata, Asteroidea), James Milton Nance

Theses and Dissertations

Pteraster tesselatus is noted for its external secretion of massive amounts of mucus. The mucus repels most animals, and fouls their respiratory physiology, if contact is maintained for any length of time. It provides protection essentially 100% of the time from Solaster dawsoni and Pycnopodia helianthoides, the only local stars that attempt to feed on Pteraster. The mucus, which is a simple mucopolysaccride, is produced in three different types of unicellular glands located in the epidermal tissues along the supradorsal membrane. Pores along the lateral walls of the ambulacral grooves provide fresh sea water for the dermal branchiae contained in …

Effect Of Hemorrhage On Blood Flow To Marrow And Osseous Tissue In Conscious Rabbits, Glenn T. Syftestad

Theses and Dissertations

The purpose of this experiment was to characterize cardiovascular responses in skeletal tissue 15 minutes and 16 hours following reversible hemorrhagic hypotension and to validate a quantitative method for measuring blood flow rates in marrow and bone.

Cardiac output and regional blood flow determinations were made using the radioactive microsphere technique. Microspheres (15 u dia) were injected into unanesthetized rabbits via a chronically implanted left atrial catheter. Blood flow and cardiac output measurements were made by injecting individual microsphere isotopes, each with a different label (®^Sr, 5 1 c r Gr l ^ C e ) , at three specified …

The Effects Upon Specific Nonverbal Behaviors Of Focusing Student Clinician's Attention On These Behaviors Through Videotape Feedback And Instruction, Pamela Hagen Gudmundson

Theses and Dissertations

The purpose of this study was to determine if a systematic approach to the study of nonverbal movements through the use of videotape playback and instruction provides a useful procedure for teaching nonverbal patterns and actions to student clinicians.

Thirty female student clinicians who had completed between ten and 400 hours of clinical practice were divided into three groups and matched according to the number of practicum hours completed by each student.

Group I received a one-hour training session which involved viewing of their videotapes accompanied by verbal instructions to attend to specific, defined, nonverbal behaviors. Group II received a …

Nonverbal Immediacy In Dyads As A Function Of Degree Of Acquaintance And Locus Of Control, Bryan D. Bartels

Theses and Dissertations

Mehrabian (1971) has summarized evidence that nonverbal "immediacy" behaviors such as interpersonal distance, gaze, and shoulder orientation are important in communicating interpersonal attraction. Several authors (Duke & Nowicki, 1972; Efran, 1968; Efran & Broughton, 1966) have conceptualized nonverbal immediacy differences between friends and strangers within the context of Social Learning Theory (SLT). Duke and Nowicki, for example, proposed that interpersonal distancing is mediated by specific expectancies in interactions among friends, but by generalized expectancies, such as locus of control (Rotter, 1972), when interactions involve strangers. Some support for this hypothesis is provided by a study showing that locus of control …

Affective Influences On Nonverbal Immediacy, Steven F. Dreyer

Theses and Dissertations

This dissertation focused on compensatory relationships among the nonverbal "immediacy" behaviors—interpersonal distance, gaze, trunk lean, and body orientation--which are hypothesized to be important in the communication of interpersonal attitudes (Mehrabian, 1972; Patterson, 1973). Argyle and Dean (1965) have proposed that in social situations there are both approach and avoidance forces (e.g., affilia- tive needs, fear of intimacy) which eventually balance at some level of mutual comfort for the interactants. Once a comfortable intimacy-equilibrium has been established, any change in immediacy by one interactant requires a compensatory adjustment by the other. Since distance, gaze, trunk lean, and body orientation are assumed …
