A Community Health Nursing Care Plan, Gayle Clark

Loma Linda University Electronic Theses, Dissertations & Projects

Structured nursing care plans are recognized tools in the effective utilization of the nursing process. Community health nursing services have not commonly used structured nursing care plans. The purpose of this study was to improve the management of patient problems through the deliberate use of the nursing process by providing the public health nurse with a structured nursing care plan. A plan was developed which consisted of a nursing history outline, a plan for action tool, and an evaluation form.

The nursing problem of milk anemia was selected to be managed by public health nurses in the study. Six nurses …

Uniform Convergence Of Lacunary Fourier Series, Julio Edgardo Barety

Mathematics & Statistics ETDs

Let G be a compact group and its dual group which we suppose to be countable. We suppose that S = {_n}_n≥0 is a non-decreasing sequence of finite subsets of having the property that = . If F is the topological dual of a homogeneous Banach space B provided with its norm topology, one can then define in a natural way convergence in norm in F with respect to the sequence S. With F one can associate two Banach spaces F_b and F_c consisting of those elements of F whose Fourier series has bounded …

Patricia-Ii Two Level Overlayed Indexes For Large Libraries., James Leon Clark

Mathematics & Statistics ETDs

PATRICIA is a Practical Algorithm To Retrieve Informa­tion Coded In Alphanumeric. The library index built by PATRICIA is entirely core resident. PATRICIA-II extends PATRICIA by building both a lower index and an upper index. This allows for the indexing of a much larger library. The lower index is core resident and the upper index is divided into upper pages which are stored on disk. At any given time only the lower index and one upper page are in core. Upper pages reference only themselves, not each other. In addition to these innovations, PATRICIA-II retains all of the features of its …

Application Of Fast Poisson Solvers To The Numerical Approzimation Of Parabolic Problems., Billy Lewis Buzbee

Mathematics & Statistics ETDs

Let T be a positive constant, let D^n be the interior of the unit hypercube in R^n with boundary ∂D^n, let a(t;x1,x2,…,xn) be a strictly positive funtion, and consider the parabolic problem ut= ∇*a ∇u + s(t;x1,x2,…,xn) in D^nx[0,T]

Where

U(t)=0 on ∂D^nx[0,T]

And

U(0)=f

This report compares three A-stable marching procedures for approximating this problem by finite differences. The procedures considered are the pure explicit procedure (APX) with 6t sufficiently restricted to insure A-stability, the pure implicit procedure (PM) or backwards difference equation, and a recently developed pure implicit procedure (SOC) which is second order correct in time and …

Patients' Reactions To Witnessing Cardio-Pulmonary Resuscitation, Lynn Andree Finch

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to describe the reactions to stress in patients witnessing a cardio-pulmonary resuscitation, in order to determine if the witnessing patients' needs are being met adequately, and to determine the effect of a specific psychological stressor on patients.

All resuscitations ("STATS") done over a two-month period at Loma Linda University Medical Center, with oriented patients in the room, were observed and recorded on an Observation Guide. A Questionnaire was also solicited from medical-surgical nursing personnel who had observed "STATS" with witnessing patients in the last three months. The Guide and the Questionnaire were developed from …

Post-Abortion Counseling And Anxiety Levels Of Unmarried Adolescents Having Therapeutic Abortions, Linda Levisen

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the effectiveness of a post-abortion counseling program. It was hypothesized that unmarried adolescents who received counseling following a therapeutic abortion would exhibit significantly fewer negative affects than those who received no counseling. The affects measured were anxiety, depression, hostility, and guilt. Twenty clients were randomly selected for this study. Prior to the abortion, the twenty clients were-tested for negative responses to the unwanted pregnancy. Ten clients received post-abortion counseling twice following the abortion and were tested at each visit for negative affective responses to the abortion. The other ten clients received no …

Branches And Completions For Real Algebraic Curves, Arthur E. Bukowski

Mathematics & Statistics ETDs

Let Q be a real ideal in a commutative ring A over an ordered field k. Do the classical results of cummutative rings hold for the ideal Q, the realradical of Q, and the real primes of A? We deal with these questions in Section 1. We prove that the minimal realprimes of Q are the minimal primes of Hence the minimal real primes of A are the minimal primes of some a_iϵ A}. A finitely generated realsimple ring isin fact a field and so any maximal realideal in a finitely generated ring A|k is a maximal ideal. …

Some Problems In Combinatorial Number Theory., Frank Ernest Higgins

Mathematics & Statistics ETDs

In this paper we consider three unrelated problems in combinational number theory. The first of these pertains to minimal residual polynomials, the second to certain group factorizations and the third to the addition of positive integers in their Zeckendorf representations.

In section II We show that for any given positive integer m there exists a unique integer monic polynomial P of least degree and whose coefficients satisfy certain inequalities with the property that m divides P(x) for every integer x. This polynomial is called the minimal residual polynomial modulo m. We then show that this polynomial assumes various forms which …

Two Emotional Factors And Weight Loss Among Females Attending A Weight Control Class, Karen Lynn Carrigg, Eileen Rae Wangerin

Loma Linda University Electronic Theses, Dissertations & Projects

A descriptive study was conducted on twenty-four females attending a weight control class to discover the effect of weight loss upon levels of self-esteem and anxiety, as an understanding of the relation of these factors to reduction and control of weight would prove helpful to community health nurses in counseling with overweight and obese persons in the community.

The entire sample was tested for self-esteem (TSCS) and A-State and A-Trait anxiety levels at the initial class of the weight control program sponsored by the Health Education Department of Loma Linda University Medical Center, and again after seven weeks of class …

Assisting Mothers To Successfully Breast Feed Their Babies, Annabelle Moore

Loma Linda University Electronic Theses, Dissertations & Projects

This experimental study tested the effect of a teaching program on success of a group of mothers desiring to breast feed their babies. It was hypothesized that mothers receiving specific instructions on the physiology of lactation and the proper sucking technique would have greater success than mothers not so instructed.

To be categorized as successful the mothers had to have an adequate supply of milk and had to express satisfaction with breast feeding. Criteria for adequacy of milk supply consisted of weight gain of the infant within accepted norms without use of supplementary formula.

Twenty breast feeding mothers who delivered …

A Clinical Comparison Of Six Orthodontic Techniques, Erik H. Madsen

Loma Linda University Electronic Theses, Dissertations & Projects

Controversy exists concerning the relative superiority of various orthodontic techniques because of the difficulties encountered in making comparative clinical studies of these techniques which are scientific and statistically meaningful. The purpose of this study was to clinically compare six different orthodontic techniques which are currently being taught, relative to a number of criteria, and to do it in a scientifically significant manner.

In order to eliminate as many of the irrelevant variables as possible, the patients were required to pass a relatively stringent screening to participate. Among other things, the patients had to have first molars in Class I relation …

Selected Factors Related To Ability To Regain Bladder Function Following Indwelling Catheterization, Jongkolnee Padmasiri

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory retrospective study was designed to evaluate selected factors, including the ability to regain bladder function related to post indwelling urethral catheterization in an acute general hospital population.

The records of 107 patients who met the study criteria became the study population. These patients had three-way urethral catheters, continuous antibacterial irrigation and closed drainage system. Twenty patients died (19 percent) before the catheter was removed. Of the 87 patients who were alive, 37 percent (32 patients) had in-adequate bladder function. Of these 32 patients, no attempt was made to remove the catheter from 15 prior to their hospital discharge. …

Selecting The Best Linear Model From A Subset Of All Possible Models For A Given Set Of Predictors In A Multiple Linear Regression Analysis, David L. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sixteen "model building" and "model selection" procedures commonly encountered in industry, all of which were initially alleged to be capable of identifying the best model from the collection of 2^k possible linear models corresponding to a given set of k predictors in a multiple linear regression analysis, were individually summarized and subsequently evaluated by considering their comparative advantages and limitations from both a theoretical and a practical standpoint. It was found that none of the proposed procedures were absolutely infallible and that several were actually unsuitable. However, it was also found that most of these techniques could still be …

A Two Sample Test Of The Reliability Performance Of Equipment Components, Miki Lynne Coleman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to develop a test which can be used to compare the reliability performances of two types of equipment components to determine whether or not the new component satisfies a given feasibility criterion.

Two types of tests were presented and compared: the fixed sample size test and the truncated sequential probability ratio test. Both of these tests involve use of a statistic which is approximately distributed as F.

This study showed that the truncated sequential probability ratio test has good potential as a means of comparing two component types to see whether or not the …

Sequential Analysis For Tolerances Of Noxious Weed Seeds, Seung Tokko

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The application of a sequential test, the sequential probability ratio test, for the tolerances of noxious weed seeds is studied. It is proved that the sequential test can give a similar power curve to that of the current fixed sample test if the test parameters are properly chosen.

The average sample size required by a sequential test, in general, is smaller than that of the existing test. However, in some cases it requires relatively a larger sample than current test.

As a solution to the problem a method of truncation is considered. A kind of mixed procedure is suggested. This …

A Review Of "Longitudinal Study" In Developmental Psychology, Emily H. Finley

Dissertations and Theses

The purpose of this library research thesis is to review the "longitudinal study" in terms of problems and present use. A preliminary search of the literature on longitudinal method revealed problems centering around two areas: (1) definition of "longitudinal study" and (2) practical problems of method itself. The purpose of this thesis then is to explore through a search of books and journals the following questions:

1. How can “longitudinal study” be defined?

2. What problems are inherent in the study of the same individuals over time and how can these problems be solved?

A third question which emerges from …

A Simple Method For The Construction Of Empirical Confidence Limits For Economic Forecasts, William (Bill) H. Williams, M. L. Goodman

Publications and Research

A simple method for the construction of empirical confidence intervals for time series forecasts is described. The procedure is to go through the series making a forecast from each point in time. The comparison of these forecasts with the known actual observations will yield an empirical distribution of forecasting errors. This distribution can then be used to set confidence intervals for subsequent forecasts. The technique appears to be particularly useful when the mechanism generating the series cannot be fully identified from the available data or when limits based on more standard considerations are difficult to obtain.

An Extension Of The Cochran Q Test, Soo-Young Cho

Loma Linda University Electronic Theses, Dissertations & Projects

The familiar x ² test is ordinarily used to compare percentage distributions of categorical data for two or more independent samples. A more accurate com parison of the percentages is sometimes obtained if the samples consist of matched individuals. The NcNemar test is generally used when comparing only two related samples. Where there are three or more samples the Cochran Q test is used. Both of these tests apply only to the case of dichotomized responses. This thesis extends the Cochran Q test to the case where the responses are multinomial. A generalized statistic corresponding to Cochran's result is obtained. …

Some Applications Of Decompositions Of The Identity To Ordered Vector Spaces., John Annulis

Mathematics & Statistics ETDs

We study decompositions of the identity (for definition see Vulikh [13]) in Dedekind a-complete vector lattices. In Chapter 1, we define and develop a notion of continuous elements with respect to a decomposition of the identity. We shall also develop a spectral theory for these elements. In Chapter 2, two Stieltjes-type type integrals are defined with respect to decompositions of the identity. The relationship of these integrals to the continuous elements is then explored. In Chapter 3, we prove two results in ordered vector spaces. The first result is that every infinite dimensional Dedekind complete vector lattice has a base …

A Maximum Principle For An Optimal Control Problem With Integral Constraints., Vernon Bakke

Mathematics & Statistics ETDs

In this problem necessary conditions are obtained for an optimal control problem ·whose state variables are given in terms of integral equations. The conditions are obtained separately for Volterra equations and Fredholm equations. The main result for each case is the maximum principle and multiplier rule. For the Volterra equations, transversality conditions are obtained.

A New Confidence Interval For The Mean Of A Normal Distribution, David Lee Wallace

All Master's Theses

A typical problem in statistical inference is the following: An experimenter is confronted with a density function f(x; ϴ) which describes the underlying population of measurements. The form of f may or may not be known, and ϴ is a parameter (possibly vector-valued) which describes the population. The statistician's job is to estimate or to test hypotheses about the unknown parameter ϴ. In this paper, we shall consider interval estimation of the mean of the normal density function.

The Effect Of Early Postpartum Teaching Of Infant Feeding On Maternal Concern, Linda M. Richter, K. Judy Toews

Loma Linda University Electronic Theses, Dissertations & Projects

An experimental study was conducted on thirty primiparae during the postpartum period to determine if individualized instruction regarding infant feeding would result in a lower level of maternal concern in this area. The study sample was randomly and evenly divided into a control and an experimental group. It was statistically determined that the two groups were homogeneous in regard to age, education, occupation, previous information (prenatal classes and reading) and help at home. The experimental group received individualized instruction by the researchers concerning their chosen method of infant feeding on the second postpartum day. There was no instruction given the …

The Effects Of A Topically Applied Anti-Inflammatory Agent On Root Resorption In The Replanted Teeth Of Canines, William L. Young

Loma Linda University Electronic Theses, Dissertations & Projects

Root resorption is a constant finding on the roots of replanted teeth. In this study it was suggested that root resorption is perhaps related to inflammation and that teeth incubated in an anti-inflammatory agent such as triamcinolone acetonide, a corticosteroid, before replantation would have less resorption. To investigate this hypothesis nineteen mature teeth in five mongrel dogs were extracted and replanted. Ten of the teeth were incubated for five minutes in the steroid and nine control teeth for the same period in a saline solution. Before euthanizing the animals at one, three, five, and seven weeks, a clinical evaluation of …
