Silica Gel: An Experiment In Surface Area, Scott Vermullen

Paper Engineering Senior Theses

Within the paper industry today, there are advancements in technology every year, every month, most likely every day as well. These new technologies work to obtain the same major goals. These goals include faster machine speeds for improved output. They-include less, pollution, and in fact are working towards a pollutant free system. And finally, product quality for today's high demanding consumer market.

To realize these goals, paper makers must effectively utilize the most amount of fiber and filler possible in their sheet. That is, they must bind up fines and filler within the sheet rather than sending it to the …

Western Michigan University Teaching Style Survey: A Nonevaluative Scale Of Teaching Style As Reported By Students, Christopher A. Lewis

Honors Theses

Students know little about the differences between professors that they may at some point come in contact. Students rely heavily on hearsay of others to learn about the teaching style of professors. This hearsay is non-scientific, relying on mainly opinions instead of fact. The Teaching Style Survey (TSS) looks at a professors' teaching style and how it relates to the students' learning style. With this information, students will be able to find professors that complement their learning style, not blindly picking the professor just to fill a time slot. This becomes particularly important when looking at multiple sections and elective …

In order to test the relationship between the elements of social …

Md Ribbing Instability Of Air Knife Coating Application, Bradley W. Fadden

Paper Engineering Senior Theses

The coating application process is an area of great concern for most mills that produce a coated media. During the roll application of the coating onto the sheet, the fluid that is passed to the sheet from the roll, goes through a process known as film splitting. Film splitting is the mechanism for the transfer of the fluid from the application roll to the sheet. Instead of smoothly transferring onto the sheet, the film splits away from the roll and then onto the substrate. Without even transfer and leveling of the coating fluid, the splitting results in stripes or ribs …

The Effect Of Antioxidant Addition On Lightfastness Of Color Ink Jet Printing, Jennifer M. Siuda

Paper Engineering Senior Theses

Fluorescent office lighting has been shown to fade ink jet colors. Fading of ink jet dyes is a problem when the shelf life of documents is important. For effective, low cost ink jet printing, the color quality of the printed paper must be maintained for a duration of time. Research in hot melt adhesives has shown a reduction of color loss associated with the use of antioxidants.

During this thesis, a coating formulation was tested with and without an antioxidant present. The antioxidants tested were alpha tocopherol I vitamin E, and sodium thiosulfate. The addition rate was varied at 2.65 …

The Effects Of Animal Assisted Therapy When Used As An Adjunct To Occupational Therapy In The Rehabilitation Of Persons Who Have Had Cerebral Vascular Accidents, Alice Arlene Briggs

Masters Theses

Occupational therapists can use animals to assist their clients in achieving goals in treatment. Most often dogs are used as they are more easily trained. The dog may fetch a ball thrown by the client or stand still and allow the client to brush it. These activities with the animal increase the client's range of motion, endurance and strength. Dogs as well as other animals are used in various ways to elicit the desired response from the client. No studies were found in the literature that examined the use of animals as adjuncts to, or as modalities in occupational therapy …

Pan, Ppn And Mpan Measurements And The Systematic Relationship Between Mpan And Macr At A Semi-Rural Site In Tennessee, George Nouaime

Masters Theses

Simultaneous measurements of peroxymethacryloyl nitrate (MPAN) and its primary and secondary precursors, methacarolein (MACR) and isoprene, were carried out for the first time in July 1995 at a semi-rural site southeast of Nashville. In addition to these compounds, peroxyacetyl nitrate (PAN), peroxypropionyl nitrate (PPN), other volatile organic compounds (VOCs) and supporting measurements were also collected in collaboration with other research groups. The mean concentrations of PAN, PPN, MPAN and MACR were found to be 485 pptv, 50 pptv, 30 pptv and 0.290 ppbv respectively. MP AN levels, which closely tracked those of MACR during the day, peaked and dropped earlier …

Mastodon, 80% Complete: Poems, Jonathan Johnson

Dissertations

Many of the poems in this collection are set in the vast woods and along the Lake Superior coastline of Michigan's Upper Peninsula. Others take place in and around the poet's remote cabin in northern Idaho where the Selkirk, Bitteroot, and Cabinet mountain ranges converge. However, they all take as their definition of wilderness the complete external beyond the individual consciousness, including the body, other people, and the decaying cultural landscape, as well as vistas of yet unmolested nature. The poems chronicle an ongoing attempt to occupy the borderlands of faith between imaginative will and allegiance to the world, that …

The National German-American Alliance, 1901 -1918: Cultural Politics And Ethnicity In Peace And War, Charles Thomas Johnson

A Study Of Factors Affecting Responses In Electronic Mail Surveys, Kimberly Post Good

Dissertations

Electronic mail is becoming increasingly popular as a means to communicate information expediently and inexpensively. One use of electronic mail that has not been well researched is its viability as a tool for data collection. A handful of studies have focused on the differences that exist in responses and response rates of electronic mail surveying compared to other methods of surveying (telephone and postal mail). One area that has not been studied at all is the factors affecting the response rates of electronic mail surveys.

This research study sought to build upon the existing research base of what is known …

An Analysis Of Police Perceptions Of Community Policing And Female Officers, Rhonda Kaye Delong

Dissertations

Traditional and community policing differ in their approach to crime and other social concerns. Traditional policing emphasizes reactive response and enforcement while community policing emphasizes proactive response and community partnership. Often, these two types of departments select officers with specific characteristics which fit well with the philosophy of the department. Characteristics such as age, education, years of military experience, rank, years of police experience, type of department, and family members in the military and the police are examined in this study to determine perceptual differences among officers regarding the community policing philosophy and the role of women in policing. A …

The Effect Of Managers' Clarification Of Business Linkage Of Training On Trainees' Transfer Of Training, Elizabeth J. Benanzer

Dissertations

This study investigated the hypotheses that if managers were engaged in specific activities aimed at increasing their understanding of the linkage of employee training to business goals, then they would in turn create a more positive transfer environment, resulting in greater transfer of training received by their employees. Some managers of trainees participated in a workshop in which they used an “impact mapping” procedure to clearly explain the relationship between training of their employees and strategic goals of the business; another group of managers did not receive this impact mapping training. Then, all managers’ employees participated in a supervisory training …

The Effect Of Remedial Education Programs On Academic Achievement And Persistence At The Two-Year Community College, Lyn Ann Batzer

Collision Spectroscopy Of Low Energy Capture By Multiply Charged Ions From Atomic Targets, Kadir Akgungor

Dissertations

State-selective differential cross sections for single-electron capture processes in very slow collisions of Ar^q+ (q = 4 - 6) ions with Ne, and Ar^6+ ions with He have been studied experimentally at laboratory collision energies between 15 and 100 qeV, and at scattering angles between 0° and 8° by means of translational energy-gain spectroscopy technique. The translational energy spectra show that only a few final states are populated depending on the charge state of the projectile, the projectile laboratory scattering angle, and the collision energy. These measurements also show that the dominant reaction channels are due to capture into excited …

An Assessment Of Generalization Across Settings Of A Parenting Strategies Program For Adhd Children, Barbara M. Todd-Nelson

Dissertations

When collapsed across gender and subject pools, Attention-Deficit/ Hyperactivity Disorder (ADHD) affects three to five percent of school-aged children (DSMIV, 1994). Intervening upon environmental contingencies for ADHD-diagnosed children is one of the least intrusive forms of treatment and is often very effective (Atkeson & Forehand, 1978; Forehand & King, 1977; Barkley, 1986; Webster-Stratton, 1993). As noted by many researchers (Allen, Tamowski, Simonian, Elliott & Drabman, 1991; Drabman, Hammer, & Rosenbaum,1979; Stokes & Osnes, 1989), it is necessary to assess generalization of treatment effects across the behavior therapy literature. Few have examined generalization from the home setting to the classroom. Since …

Programmed Instruction: Within-Subject Analysis Of Four Types Of Instructional Material, Matthew L. Miller

Dissertations

Skinner (1958) expressed the need for an increase in the effectiveness and efficiency of education. In particular, he suggested that programmed instruction could provide such efficiency. The present study used a within-subject design to compare the effects of four types of instructional materials: those requiring overt construction responses, overt discrimination responses, covert reading of text with highlighted key words, and covert reading of standard text. The material requiring overt responding produced greater learning than did the covert reading materials, with or without highlighting. There was no difference found between the two types of overt responding; nor were there differences between …

Theoretical And Conceptual Lacunae In Sociological Theories Of Development: The Puerto Rican Anomaly, Dennis Malaret

Dissertations

Puerto Rico is presently facing serious economic and social problems which are characteristic of a neocolony. Many of these problems are associated with Puerto Rico's historical path of industrial development adopted in 1940s. This study, therefore, focuses on economic and development policies implemented in Puerto Rico since the early 1900s and the political and economic role the U.S. has played in such policies.

To understand Puerto Rico's structural problems, a theoretical framework has been developed. This framework combines developmentalist theories such as modernization, dependency, capitalist world economy and indigenous Puerto Rican theorizing. These theories have been critically assessed for their …

Affective Orientation, Alexithymia, And Multidimensional Empathy In Counselors-In-Training, Terrilyn J. Krueger

Dissertations

The purpose of this study was to investigate the predictive relationship between two affective measures, affective orientation and alexithymia, and five empathy measures in 67 master’s degree level counselor trainees. It was hypothesized that affective orientation would be predictive and alexithymia inversely predictive of five distinct dimensions of empathy: communicated, observed, emotional, cognitive, and relational. Communicated empathy was measured by trainees’ audio-taped responses to a client stimulus which were assessed by “blind” raters. Observed empathy was measured by practicum supervisors based on their observations of trainees with clients. Emotional, cognitive, and relational empathy were assessed by trainees’ self-reported responses about …

A Portrait Of Assessment In Reformed Mathematics Classrooms, James R. Kett

Dissertations

During the past decade, the National Council of Teachers of Mathematics published three documents (1989, 1991, 1995) which propose changes in content, instruction, and assessment. These documents call for instructional and assessment goals that support students as they construct their own meaning to mathematics. A next step is to develop assessment models consistent with these goals which would guide and support classroom teachers.

As a result of mathematics reform, many curriculum development projects are underway. One such project is the Core-Plus Mathematics Project (CPMP) . This research documents the assessment practices of four CPMP teachers working in 9th and 10th …

Subjects individually performed four computerized work tasks (SYNWORK) simultaneously, and the total number of points earned on the tasks was the main dependent variable. A within-subject reversal design was used, with hourly pay (A), individual (B) and group (C) monetary incentives implemented in an ABCB pattern. Subjects, when working under the group incentive pay condition, were told that the number of points they earned during each session would …

Civil Society In Palestine: A Palestine Profile, Shadia Kanaan

Masters Theses

One definition of civil society dominated all theoretical and historical perspectives when it comes to the special case of civil society in Palestine. "Civil society is concerned with a society's total self re-producing ability through its inner strength in a manner that is distinct from the state" (Bishara 1995, 143). The hypothesis of this work is that civil society in Palestine existed and flourished in spite the absence of a national state and had played a fundamental role in the social and economic development of Palestinian society throughout its history. Civil society in Palestine poses an exception to the theory …
