Energy Impacts Of Water Based Recreation, J. Clair Batty, David A. Bell, E. Bruce Godfrey, Craig Howell, J. Paul Riley, Thomas C. Stoddard

Reports

The overall objective of the study reported here was to determine to what extent energy accounting could supplement and/or complement economic benfit/cost analyses of water management projects and to specifically examine the energy impacts of water based recreation. The energy accounting literature was carefully reviewed and an energy accounting methodology applicable to water management was devised. Data pertaining to receation at five reservoirs in Utah were assembled from visitation recoreds and on-site surveys. Energy requirements for site construction, travel to and from the recreation site, and recreation at the site were estimated. It was determined that energy devoted to water …

The Influence Of Salinity On Larval Development And Population Dynamics Of Anopheles Merus Dönitz (Diptera: Culicidae), F. W. Mosha, C. M. Mutero Jan 1982

The Influence Of Salinity On Larval Development And Population Dynamics Of Anopheles Merus Dönitz (Diptera: Culicidae), F. W. Mosha, C. M. Mutero

All Peer-Reviewed Publications

Variations in density of adults of Anopheles merus Dön. in Jimbo Village on the Kenya Coast were found to be correlated both with rainfall and with salinity at their breeding sites. Densities started to increase at the beginning of the rains when several breeding sites were formed. This was followed by a decline in numbers resulting mainly from the decrease in salinity in the semi-permanent breeding sites. A second rise occurred after the end of the rains, corresponding with an increase in salinity in the semi-permanent breeding sites due to evaporation. Peak density coincided with salinities of 30–50% sea water …


Extensions, Generalizations, Characterizations And Testing For Independence Through Infinite Divisibility, Edward Joul Danial Jan 1982

Extensions, Generalizations, Characterizations And Testing For Independence Through Infinite Divisibility, Edward Joul Danial

Doctoral Dissertations

This dissertation investigates various related topics around the exciting concept: "Infinite Divisibility." First, two intricate distributions, namely, the univariate generalized Waring and the hyper-Poisson are proved to be infinitely and noninfinitely divisible, respectively. Analysis and computer approaches are employed. This itself extends the use of some results introduced by Katti, Steutel and Warde. Secondly, generalizations to Warde, Katti and Steutel's sufficient conditions and related results are achieved. Then, numerical application is presented. Thirdly, characterizations through infinite and finite divisibility are obtained. The Poisson, negative binomial, geometric, Bernoulli and uniform c haracterizations in terms of infinite divisibility are deduced. Some of …


Absolute Theory Of Relativity & Parameterized Special Theory Of Relativity & Noninertial Multirelativity, Florentin Smarandache Jan 1982

Absolute Theory Of Relativity & Parameterized Special Theory Of Relativity & Noninertial Multirelativity, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

In this book we present our 1972 hypothesis that there is no speed barrier in the universe and one can construct arbitrary speeds -

thus refuting the speed of light postulate.

While Einstein considered a relative space and relative time but the ultimate speed

of light, we do the opposite: we consider an absolute time and absolute space but no

ultimate speed, and we call it the Absolute Theory of Relativity (ATR). The ATR has no time dilation, no length contraction, no relativity of simultaneity, and no relativistic paradoxes.

We then parameterize Einstein’s thought experiment with atomic clocks,

supposing that …


Outwitting The House Sparrow [Passer Domesticus (Linnaeus)], William D. Fitzwater Oct 1981

Outwitting The House Sparrow [Passer Domesticus (Linnaeus)], William D. Fitzwater

Great Plains Wildlife Damage Control Workshop Proceedings

With the decline of house sparrow populations during the first quarter of this century, control research attention shifted to other avian species so little new is available on either life history studies or management. Solutions to animal damage control problems are generally through (1) environmental controls, (2) protection of crops and/or sites, and (3) population reduction. In the case of sparrow problems, environmental controls are of limited application as the birds prefer the habitat modifications made by man. Protection of crops or sites relies on repellents which are generally ineffective against this particular species. The only viable population level controls …

Mathematics As Rhyme, Vern Poythress Jun 1981

Mathematics As Rhyme, Vern Poythress

ACMS Conference Proceedings 1981

Using the analogy between the universe and a choral poem, one may view mathematics as the “rhyme” of the universe. In that perspective new light is thrown on the unique subject matter of mathematics, the a priori character of its truths, and the relation of mathematics to other areas of knowledge. A route is thereby opened for richer use of creativity in mathematics.


Science As Allegory, Vern Poythress Jun 1981

Science As Allegory, Vern Poythress

ACMS Conference Proceedings 1981

The universe is God’s choral poem, and science is a system of allegories within it. That is the thesis that I propose to expound and defend. Yet it is not a “thesis” at all, if the word “thesis” commits me to a certain kind of strict logical defense. I am not putting forward my thesis that science is allegory as the endpoint of a deductive or inductive argument. Rather, it is a springboard for a program of exploration and reflection that turns upside-down some conventional ways of thinking about science.

Support Systems Of Mexican-American Women And Their Attitudes Regarding Infant Feeding, Susan Marie Krantz

Loma Linda University Electronic Theses, Dissertations & Projects

This was a descriptive study of 37 recently migrated to the United States, Spanish-speaking, Mexican-American women. Attitudes and support systems associated with their choice to breast or bottle feed their infants were studied. The purpose of this research was to answer the following questions:

1. What are the differences in the attitudes of Mexican- American primiparas who choose to breast feed and those who choose to bottle feed?

2. What are the differences in the practice, recommendations, and proximity of location of significant members of the women's support systems?

Twenty-one breast feeders and 16 bottle feeders were interviewed in Spanish …


A Hybrid Metric To Measure Software Complexity, Warren Harrison, Kenneth I. Magel May 1981

A Hybrid Metric To Measure Software Complexity, Warren Harrison, Kenneth I. Magel

Computer Science Technical Reports

Software complexity is an important facet of the software development process, especially in regard to maintenance. A number of complexity metrics have been developed to measure the complexity contributed by: program size, flow of control, data structures, or a combination of two or more of these. Several representative measures from each of these groups are described.

A new hybrid complexity metric, the Extended Scope Metric, is presented and compared with other popular complexity metrics. While the new metric appears to be an improvement over existing metrics due to its enhanced context sensitivity and comprehensiveness, conclusive results cannot be determined until …


Lifestyle As A Determinant Of Participation Among Dispersed Forest Recreationists, John R. Butler May 1981

Lifestyle As A Determinant Of Participation Among Dispersed Forest Recreationists, John R. Butler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study assesses the usefulness of lifestyle as a determinant of outdoor recreation behavior. Two objectives of the study are: (1) develop an operationalized concept of lifestyle that is based on theory, and (2) apply this concept in a model which uses lifestyle as a variable influencing recreation behavior.

The first objective was approached through an integrative review of the literature. Lifestyle was set in context of cultural theory. The basic postulate of the proposed theory of lifestyle is: If an individual's lifestyle is similar to that of another, certain social psychological processes are similar. Therefore, their patterns of needs, …

A System For The Observation Of Voles Under Semi-Natural Conditions With Applications To: Social Interactions, Competition, Food Habits, Habitat Preference And Bait Accpetance., D. S. Wilkie, M. A. Novak

Eastern Pine and Meadow Vole Symposia

A laboratory system to study microtine rodents has been developed that avoids many of the intrinsic restrictions of earlier laboratory and field studies. The system is composed of two interconnected plexiglas tables with a soil substrate and hay cover. The system permits unconstrained visual observation of voles as they move within a runway network of their own construction. The flexibility of the system facilitates its use in various avenues of microtine research.

A Suggested Course In Introductory Computer Programming, Warren A. Harrison, Kenneth I. Magel Jan 1981

A Suggested Course In Introductory Computer Programming, Warren A. Harrison, Kenneth I. Magel

Computer Science Faculty Research & Creative Works

Introductory programming courses have long been a popular topic of discussion. Often it is either the only computer course a student takes, or it is the foundation upon which all further training in computer science is built. The usual goal of such a course is to introduce the student to the use of a computer to solve simple problems in his or her particular discipline. Generally, the method of presenting the material may be separated into two distinct schools of thought, which we have termed the "Black Box School of Thought" and the "White Box School of Thought". In this …

Regulation Of Biomedical Research, Andrew N. Rowan Jan 1981

Regulation Of Biomedical Research, Andrew N. Rowan

Experimentation Collection

The idea of abolishing or simplifying government regulations has a large following in Washington at the moment. As Reagan and his minions start to prune the growth of the past twenty years, we must hope that they are able to distinguish between the healthy growth which provides needed support and the unnecessary growth which strangles necessary initiatives. However, there is one area where we need more regulation rather than less, namely, biomedical research. In calling for more regulation in biomedical research, I do not mean the imposition of outside controls by allegedly ignorant and insensitive bureaucrats (although I think some …


Visual Impacts Of Forest Management Activities: Findings On Public Preferences, United States Department Of Agriculture, Forest Service Jan 1981

Visual Impacts Of Forest Management Activities: Findings On Public Preferences, United States Department Of Agriculture, Forest Service

Forestry

A major concern of forest land managers is the visual impact that activities such as timber harvest, road building, and mining have on the forest landscape. Management of the visual resource is a regular part of planning on National Forests, and many other public and private forest land managers are increasing their efforts to protect and enhance this resource. The Forest Residue and Harvesting Research Program at the Intermountain Station includes studies of the impact of harvest and roading activities on visual quality. Preliminary results were reported earlier (Schweitzer, Ullrich, and Benson 1976). This report updates earlier findings and presents …

The Quality Outdoor Recreation Component In Multi-Purpose Conservation Areas: A User Assessment Devised, And Applied To Pinehurst Lake Conservation Area, Gerald Carl Thomas Jan 1981

The Quality Outdoor Recreation Component In Multi-Purpose Conservation Areas: A User Assessment Devised, And Applied To Pinehurst Lake Conservation Area, Gerald Carl Thomas

Theses and Dissertations (Comprehensive)

Recreational demand for out-of-doors space and facilities continues to increase into the 1980’s. Accordingly, multi-purpose conservation areas, by the nature of their designations, require ongoing assessment of the attributes which determine the quality of the recreational experience they afford.

A problem with the master planning process for these multi-use areas is that in the past, little or no consideration has been given to user-recreationist input in the development stages of the master plans. The purpose of this study is to devise a method of assessing user satisfaction towards the recreational quality available at multi-use conservation areas, and to show how …
