Human Resource Planning For Mergers And Acquisitions, Thomas Jide Fiki

Theses

When a firm is acquired or merged, everyone feels shaken.

When organizations merge, the people in them are touched by several real and poignant issues, with each issue having the potential for lowering morale and productivity. When mergers or acquisitions fail, either by falling short of stated objectives or more disastrously - by divestiture - a chief culprit is often inadequate or nonexistent human resource planning.

A solid people plan - which takes into account what and how to communicate before and during a merger not only helps retain a semblance of order and direction within the company facing a …

Empirical Study On Employee's Ownership, Anthony Chuks Ibida

Theses

Employees Ownership in the United States has been in existence for many years and it seemed to be a utopian idea of no real consequence to the general public. Now employee ownership has gone a drastic change and it has become a major focus of media attention, and we are observing an extra ordinarily rapid increase in interest and involvement among practitioners in law, banking, and organizational consulting, along with growing government interest.

As the name indicates employees ownership or worker cooperative firms have a long but spotty history in the United States. Some researchers traced over eight hundred firms …

Separation Of Chromium From Waste Sludges By An Electric Membrane Process, Freeman Nai-Tchun Ho

Theses

The process is characterized by using metallic membrane as a filter which is charged by a separate DC-power supply and it may become experimentally very effective in increasing the separation potency and migration flux. The technique of integrating migration with electromembrane was evaluated for the removal of chromium. The transport was found to be adequately described by an equation in which the rate is proportional to the chromium concentration. The rate of dichromate ions transported across the membranes and the gel water content of membrane increased when the ratio of electromembrane potential and cell system potential was increased. The back …

A Data Compression System Using Arithmetic Code, Seokrim Choi

Theses

Generally it is difficult to compress data, from statistically unknown sources, with significant compression ratio. To achieve this, the compression scheme should have an ability to gather context information of the source, adaptively. For better compression, it is desirable to separate the context gathering scheme from coding itself. Arithmetic code is very flexible and can accept any kind of context gathering scheme which can generate probabilities. One context gathering algorithm which generates Markov type probability adaptively is studied and implemented in software using Arithmetic code. This scheme performs well and results in compression ratio better than any existing algorithms such …

Recruitment Of Engineers In A Small Company, Robert Cohen

Theses

With most recruitment techniques written for large companies, recruitment of engineers in a small company may be a large problem. A detailed analysis of the engineering employer and employee is constructed making note of large and small company differences.

Just-In-Time In The United States : Culture And Competitive Manufacturing, Wolfram Pabst Von Ohain

Theses

Richard Schonberger, 'the' Guru of Just-in-Time' in the United States, wrote in the preface of his 1986 book World Class Manufacturing:

"...Japanese success is rot mature-based. Its basis is a quite different set of concepts, principles, policies, and techniques for managing and operating a manufacturing enterprise. All of it is easy to understand, not hand to accept (once known), eminently teachable and learnable, and not so difficult to apply.

If Just-in-Time is such 'a piece of cake' one would expect that most American companies would practice Just-in-Time. As commonly known, most American companies do not follow the philosophy of Just-in-Time. …

An Investigation Of Quantification Of Image Quality With Respect To Screen Ruling On The Appearance Of Multicolor Print, Yi-Sheng Lu

Theses

Using a finer screen ruling will result in an improved final image quality in the color printing process. Studies have shown that beyond certain screen frequencies any further increase in the number of lines per inch has negligible benefit on multicolor process printing when using the half-tone printing precess. The objective of this research is to quantify the image quality of multicolor process printing by comparing the results of using several different screen rulings. The final image quality was subjectively evaluated based on the appearance of otherwise identical reproductions with the only difference being the screen ruling. The results of …

A Study Of The Discernibility Of Electrophotostatic Copied Typestyles As Compared With Non-Electrophotostatic Copied Typefaces, Laura A. Melchionne

Theses

This paper reports the results of an investigation into the discernibility of seven typefaces when overlayed by 15 different gauges brought into contact with each type face. Discernibility was tested under two conditions; standard (original typeset words) and electrophotostatically copied (second generation copies of the original typeset words) . The question that this investigation was attempting to answer was whether or not certain typefaces are more discernible after electrophotostatic copying than other typefaces. The seven typefaces were chosen because they have a known aesthetic preference that can be catergorized in three groups; most preferred, inbetween and least pre ferred. Preference …

A Study Of Toray's Negative Working Driographic Printing Plate And The Effect Ink Tack Has On Toning In The Non-Image Area, Larry M. Capitano

Theses

Driography is a planographic printing process. A driographic printing plate differs from a conventional offset lithographic plate in that water is not required to keep the non-image area clean of ink during printing. Water, or fountain solution, is not required during printing because a silicone rubber coating which repels ink is used for the non-image area of a driographic plate. The first driographic plate was introduced in the early 1970's by the 3M Company. The plate was a positive working printing plate and has since been discontinued. Driography has since been researched by a number of companies but only one …

A Finite Element Solution Of Thermal Wave Propagation In Elastic Media, Dominic N. Dalo

Theses

The rational theory of thermodynamics is used to develop equations governing the propagation of thermal waves. A new vector quantity is introduced to account for the thermal waves. The phenomenon of thermal wave propagation is illustrated by considering the problem of one-dimensional heat conduction in a finite slab subjected to a heat flux pulse. The solution is obtained via the finite element method. A discussion of the results and their significance is also presented.

The Effect Of Solid Ink Density On Shifts In Hue In Gray Component Replacement, Hans P. Kellogg

Theses

With advances in computer storage and electronic dot generation scanners a new color separation process has become possible. Although in theory the Gray Component Replacement (GCR) process has been possible since the early twenties, it has only recently been available through contemporary color separation methods. GCR is the process by which the gray component of a particular color reproduction is removed from the reproduction and replaced with black ink. The gray component is defined as specific combinations of the least predominant color and the other remaining inks. A printing form was designed to include three different color reproduction processes: the …

Alternatives To Lay Off, Davidson Nwaneri Okere

Theses

In the recent years, there have been some changes in the American corporate life. These changes have been occasioned by some external factors which adversely affect the profitability of the companies. In order to address this problem, many corporations have resorted to cutbacks which more often than not, affect a great bulk of the human resources.

The purpose of this study therefore, is to explore the strategies which companies could use, rather than lay off, during business downturns; and still remain competitive and profitable.

Chapter one of this study focuses on what companies should do to help the affected workers …

A Model For Automatic Optical Scaling Of Type Designs For Conventional And Digital Technology, Bridget Lynn Johnson

Theses

In the history of type design, two methods have been used to scale type-- to produce enlarged or reduced letterforms from a reference size. With original handcut fonts, designers performed optical scaling (scaling by eye) that varied the proportions of letterform features over a range of sizes in a nonlinear manner. That is, letterform feature proportions were size dependent. This was an entirely manual and intuitive process. More recently, however, the use of the lens, as well as computational and other technologies, has allowed letterforms to be scaled automatically from a reference character, a simple proportional enlargement or reduction. To …

A Null-Balance Visual Densitometer, Ramon P. Baez

Theses

This thesis deals with the development of a Visual Densitometer, for measuring transmission density, called a "Null-Balance Visual Densitometer". This is a simple instrument made using a calibrated continuous tone negative step wedge. It was used for measuring continuous tone reference patches as used for process control of color separations, in place of an electronic densitometer. The measurements were made by a comparison between the control step wedge and the samples in close proximity over a light table. The basis for this instrument is the human eye's ability to differentiate between two areas of brightness in close proximity. The study …

Culture In Vivid Color: The Villa Montezuma Windows, Marit Velma Zinko

Theses

For a full century the cultural significance of the large stained glass windows at the Villa Montezuma has been misunderstood. Now, with all the expense, effort, and energy expended to restore this beautiful historical house, it is both appropriate and timely to take a closer look at this legacy so that it can be fully appreciated and enjoyed by future generations. To properly understand these windows it is necessary to first take a brief but close look at Jesse Shepard, to understand what kind of man he was in 1887 when he came to San Diego; next to take a …

White Chief: The Story Of Edward H. Davis, Charles Mitchell Hudgins

Theses

With Mother Earth for a couch, To sleep under the fragrant conifers; To breath the purity of the ranges; To watch the procession of the constellations; To listen to the music of the wind harps of the sierras; To leave care, worry, responsibilities behind us; To be in harmony with nature at all times; To live simply, to think severely, the love deeply, to be content; And to learn patience and tolerance from the mighty mountains; That me thinks is to be happy. Edward H. Davis Mesa Grande August 26, 1933

Characterization Of Monoclonal Antibodies Against Digoxin, Susan K. Alexandrovich

Theses

Five antibodies directed against digoxin were grown and characterized. Two separation techniques were tested to find the better method of separating bound the free fractions of ligand after competitive reactions with the antibodies. Charcoal separation was chosen. The antibodies were analyzed for affinity constant by the Scatchard Analysis. Cross reactivity data for two of the antibodies were collected. Four of the antibodies have satisfactory affinity constants for use in a digoxin assay. Cross reactivity studies showed varying amounts of cross reactivity with digoxin metabolites, but none with the steroids and lipid tested.

Signature File Access Methodologies For Text Retrieval: A Literature Review With Additional Test Cases, Karen Caviglia

Theses

Signature files are extremely compressed versions of text files which can be used as access or index files to facilitate searching documents for text strings. These access files, or signatures, are generated by storing "hashed" codes for individual words. Given the possible generation of similar codes in the hashing or storing process, the primary concern in researching signature files is to determine the accuracy of retrieving information. Inaccuracy is always represented by the false signaling of the presence of a text string. Two suggested ways to alter false drop rates are: 1) to determine if either of the two methologies …
