The Halftone Effect In Color Photographic Enlargements, Rick Crowsey

Theses

In continuous-tone photography, a 'Halftone Effect" sometimes occurs that alters the tone reproduction in a distinctive way. Highlight contrast is decreased and middletone densities are lowered. Published data show that this effect occurs in black-and-white photography when the grain pattern of the negative is reproduced very sharply in the print . High-magnification enlargements are especially susceptible. Does a corresponding effect occur in color photography? A search of the literature reveals no answer. The research here described is to determine, by direct measurements of densities in sharp and blurred enlargements, the magnitude of the halftone effect in particular color enlargements from …

The Effects Of Training Parents In Divergent Questioning On The Creativity Of The Pre-School Child, Judith E. Brown

Theses

This study was designed to investigate whether teaching mothers to ask divergent questions would have a direct effect on their four year old child 's creativity. It was hypothesized that children whose mothers received the training in divergent questioning techniques would do better on a test of creativity than children whose mothers, did not receive the training.

Twenty mother and child groups were included in the study. The twenty were divided randomly into two groups, ten groups to receive the treatment and ten to receive no treatment. Six treatment sheets were then administered in the homes to the experimental group …

The Effect Of Temperature And Relative Humidity During Drying On The Covering Power Of Processed X-Ray Films, John M. Lauffer

Theses

With the constantly decreasing silver reserves and correspondingly higher costs, film manufacturers are continually searching for methods to reduce the amount of silver that is used. By using closely controlled conditions of temperature and saturated salt solutions to provide control of relative humidity during drying of processed x-ray film, it was found that the covering power may be as low as 70$ of its maximum value depending on the conditions used for drying the film. The highest values for covering power existed when the film was dried at low temperatures and high relative humidities or high temperatures and low relative …

Image Degradation In A Diffusion Transfer Process, Peter Petch

Theses

The Diffusion Transfer Process is now widely used in the Graphic Arts industry, and it is important to determine to what length different factors affect the optimum use of it. The effects of exposure, age of the processing solution, and line frequently on the image quality of the Kodak PMT system were studied. Exposure was varied by exposing the material to a standard illuminance for different amounts of time; the processing solution was aged by bubbling air through it for varied amounts of time; line frequency was varied by using a Kodak sinusoidal target and examining the images of two …

Edge Sharpness Effects On Computer-Generated Holograms, Clinton S. Potter

Theses

Computer-generated holograms refer to a class of holograms which are produced as a graphical output from a computer. This paper investigates the relation. ship between the resolution in the system used to re duce the graphical artwork to a reasonable size for diffracting light and the quality of the reconstructed hologram. A number of reduction schemes are examined including a one-step reduction onto a general purpose film, a one-step reduction onto a high resolution film and a two-step reduction scheme using coherent illumination during the second reduction.

Scene Illuminate Effect On Additive Two-Color Reproduction, John C. Manfredo

Theses

Whether a two-color reproduction from a red and green additive process is acceptable depends largely on the nature of the scene and its illumination. Additive two-color reproduction will be explored here using different scene illuminants and also different red and green filter combinations. Two projection methods are also examined. Red and green separations were produced by photographing a scene through 16 different filter combinations and 3 different scene illuminants. These separations are then projected two different ways. One method involves projecting the separations back through the red and green filters they were taken through, while in the other method the …

A Comparison Of The Random Dot And The Conventional Halftone Printing Process With Respect To Color Characteristics, Sanat Hazra

Theses

A comparative study was made of random dot printing and conventional halftone printing with respect to color characteristics. Random dot printing is similar to continuous tone printing or very high frequency screen ruling and is capable of overcoming the limitatio of halftone printing. The randomly selected dots are achieved by the grain structure of the pre- sensitized printing plates. The advantages and the disadvantages of this process over conventional halftone printing process are discussed. The images and the test targets of both the processes were exposed to, and printed from a single plate for each process color so as to …

Predicting Color Print Filtration And Exposure, James A. Klingshirn

Theses

A method of mathematically modeling the response of a system in which color reflection prints are made from a negative was investigated. Data was generated by making a series of prints with different yellow and magenta filtrations at a series of exposures. First, second and third order regression curves were fit to the filtration versus reflection density curves and the exposure versus density curves that were thus generated. The predictions of the sets of equations were compared to the data and it was found that the filtration could be predicted more accurately than the exposure time, because, the response curves …

Bibliotherapy To Help Young Children Cope With Their Problems, Marjorie J. Semon

Theses

Since children are facing many stresses both from within and without, it is felt that bibliotherapy may be a way of helping them face and cope with their problems. After a search to see if a curriculum guide had been developed to help kindergarten children through bibliotherapy, none was discovered. An extensive review of existing literature was then made to learn about children and stress at the pre-operational level, as well as an in-depth study of bibliotherapy from its history, research on bibliotherapy pertaining to young children, the qualifications of the bibliotherapist, how one determines whether the need exists, and …

Written in 1981 as part of the Master of Arts in Voluntary Association Administration Program at Lindenwood College, the paper provides both a theoretical and practical examination of interest group dynamics and advocacy strategies within human service networks.

The paper begins by tracing the historical development of interest groups and their theoretical underpinnings, highlighting contributions from political thinkers such as James Madison, John C. Calhoun, and E.E. Schattschneider. It …

The Study Of Factors That Affect Cell Depth During Etching In Direct Transfer Gravure, Somchai Sringkarrinkul

Theses

This thesis is to study the four main factors which affect cell depth in copper cylinder etching in direct transfer gravure, and using ferric chloride as an etchant. The multivariate regression method was used to analyze the sample responses (cell depth) of nine different treatments of an etched-screened-tone scale . The regression equations for predicting cell depths from the four variable factors were calculated and the optimum condition which would give the best tonal gradation was predicted. Also the factors which cause uneven cell depth were detected.

Systems Approach To St. Louis State Hospital's Referral Program, Reza Vahidi

Theses

This thesis presents a systems approach to analyzing and redesigning referral and billing processes at St. Louis State Hospital in Missouri. Recognizing the growing complexity of hospital operations, the study applies systems theory to evaluate inefficiencies in the hospital’s referral program, particularly in its interactions with external agencies and community physicians. The hospital historically relied on manual procedures and fragmented communication methods that contributed to delays, inaccuracies, and underutilization of available resources.

The study examines the referral workflow from intake to admission, identifying systemic bottlenecks and proposing structured changes to improve coordination. Emphasis is placed on streamlining communication between hospital …

A Descriptive Survey Of Rural Doctor Procurement Programs, J. H. Seitz

Theses

Various techniques have been used by many rural communities in an effort to recruit and maintain physicians. However, evidence indicates that if the doctor procurement program gets the community involved, results will surely follow. The community effort basically is the one factor that helps recruit and maintain physician manpower to their community. The doctor procurement committee is the foundation to form a solid structure that shows the physician that there is cooperation, dedication, desire and a sense or belonging. It is these factors, along with others discussed in this thesis that convinces the physician to relocate in the rural community.

Some Observations On The Development Of Pharmacy And Recommendations For Improving The Allocation Of Resources At St. Joseph's Hospital, Ivy Ann D. Lee-Sharpe

Theses

It is the intent of this paper to trace the developmental history of pharmacy alluding to the profession as an integral part of medicine when treatment was simple, magically connected and filled with superstitions. It separated when medical knowledge expanded, technology advanced and regulations formalized pharmacy. Social and environmental factors established the needs for specialists to handle, compound, prepare and dispense drugs and medicines. The institutionalization of care and the entrance of the pharmacists in these institutions were influential in this separation and will be discussed. Although formally separated, pharmacy stayed intimately linked with medicine in literature and formal education …

Laboratory Experiences In Listening Comprehension For English As A Second Language Program, Sima Mokhtari

Theses

This study is undertaken in an attempt to help teachers to consider listening comprehension as a skill which is different from pronunciation, reading, and writing. Comprehending the second language is one of the most difficult tasks for the language learner and it is the most neglected skill in second language teaching. This neglect sterns from our ignorance about the nature of the process of listening comprehension, and from the lack of our knowledge about techniques on what and how to teach students to comprehend the spoken language.

The listening comprehension skills are separate from pronunciation and grammar. This paper presents …

Granularity: Investigating Equations That Convert (T) To (D), Frederick Catt

Theses

An investigation was done on three published expanded equations, that convert (T) to (D). T. Celio, J. Altman and M. Abouelata published equations of the same form, but with differing constants. Their equations were derived by using an assumed square-wave transmittance trace. The investigation was to find the best predictor of (D) from (T) . Both practical and simulation tests were run. The density range was extended, to check for failure at both high and low densities. Standard granularity measurement procedures were followed as close as possible. Results, from the practical tests, showed Altman 's equation the best predictor of …
