Mental Health Services In Schools: School Psychologists' Current Practices And Perspectives, Nicole Carlson

Dissertations and Theses @ UNI

It is estimated that approximately 7 .5 to 9 million children and adolescents are in need of mental health services, but that only 20% of these youths actually receive the services they need (National Association of School Psychologists [NASP], 2002). Because of this, schools across the nation have begun to take preventative measures, specifically school-based mental health services. School psychologists are uniquely prepared to provide these services, but little attention has been paid to their needs and concerns regarding such services. Therefore, members of NASP were given a survey to assess current practices and perspectives regarding mental health services in …

The Effects Of The Nutriactive Healthy Experience Intervention On Nutrition Knowledge In Kindergarten And First Grade Students, Jennifer Marie Bruss

Dissertations and Theses @ UNI

Over the past 30 years obesity in elementary school age children has gone from almost non-existence to common place. With obesity on the rise, the occurrence of diseases associated with it such as Type II diabetes, hypertension and dyslipidemia have also risen for children. These diseases are often carried into adulthood since overweight children are more likely to become overweight or obese adults. This will create another generation of obese children, continue to strain a failing health system, and add additional problems to our economy as the current obese generation heads into retirement.

An Analysis Of Intuitive Eating Among College Students, Danielle Marie Vsetecka

Dissertations and Theses @ UNI

In response to the world's increasing obesity rates, the use of traditional dieting and weight loss techniques is at an all time high. Although dieting rates have rapidly increased, the world's rising obesity rates show no sign of slowing and the effectiveness and effects of dieting have long been questioned. As an alternative to dieting and exercise, a non-dieting approach to weight regulation has emerged. Intuitive eating is one of its main tenants and is defined by allowing individuals to listen to internal body cues to determine hunger and fullness levels to meet nutritional and physical needs. However, few studies …

The Effects Of Facial Attractiveness, Weight, And Immediacy On Social Influence: A Test Of Dynamic Social Impact, Melinda Bullock

Dissertations and Theses @ UNI

Social impact theory (Latane, 1981) explains social influence as a multiplicative function of strength, immediacy, and number. Dynamic social impact theory (Latane, 1996a) states that four phenomena occur as a result of social influence: a) clustering (those living close together have similar attitudes), b) correlation (once unrelated attitudes become associated), c) consolidation (reduction in overall attitude variance), and d) continuing diversity (in spite of social influence attitudes diversity persists). This study used these two theories to examine how facial attractiveness, weight, and immediacy affect social influence. It. was expected that clustering, correlation, and consolidation would occur to a greater extent …

An Examination Of Group Agreement Among Functional Ankle Instability Participant Inclusion Criteria, Shantelle A. Howe Weichers

Dissertations and Theses @ UNI

Functional ankle instability (FAI) has been commonly identified in the literature as a cause of ankle injury and dysfunction. However, the participant selection criteria for FAI research have not been consistent. Numerous authors have used various selection criteria, with seemingly no two criteria being alike. Although these inconsistencies in FAI research participant selection criteria may explain the contradictions that have been reported in FAI research, the true nature of these selection criteria differences is unknown. It is uncertain exactly if, and to what magnitude, these selection criteria differed. The purpose of this study was to examine group agreement regarding selection …

A Case Study Using Guided Reading And Teacher Read-Alouds While Monitoring English Language Learners' And Native English Speakers' Reading Achievement, Kelsey M. Baker

Dissertations and Theses @ UNI

The number of English Language Learners (ELLs) in the United States continues to increase (U.S. Census Bureau, 2002); therefore, schools and educators are affected by the growing differences in students' language skills, prior experiences, and progress. This research addresses the need for understanding ELLs and how ELLs benefit from adults effectively reading aloud to them. Further research is needed on effective reading instruction for ELLs for several reasons. First, teachers are becoming ELL teachers by default and feel overwhelmed because of the responsibility to teach both language and content (Gersten, 2002). Second, an achievement gap exists between ELLs and native …

Machining Process Changes As A Function Of Surface Roughness, Specific To Machining Cylindrical Bores, Thomas Patrick Olsen

Dissertations and Theses @ UNI

Manufacturing needs to minimize non value added costs such as reducing inventory, (non machined and finished goods), reduce work in process, and most of all eliminate waste. To exist, customers must be satisfied at the time of purchase and throughout the products lifecycle. To be competitive and remain a world class manufacture, companies must be flexible and be willing to change. Single point flexible manufacturing versus fixed spindle rigid machining greatly improves the ability to make changes. If a process …

Quantifying Granivory In A Reconstructed Prairie: Affects Of Season, Species, Seed Predators, Sacrificial Food, And The Chemical Deterrent Capsaicin, Craig M. Hemsath

Dissertations and Theses @ UNI

Floral diversity of reconstructed prairies is often low compared to remnant prairies. Studies have demonstrated it is feasible to increase forb diversity in these prairies through overseeding and mowing, but overall rates of seedling establishment range from 0.1% to 1% of sown pure live seed. One explanation may be the ubiquitous populations of granivorous animals eating much of the seed . In this thesis I measured the amount of granivory occurring in a reconstructed prairie. I also tested how season, seed species, seed predator, sacrificial food, and chemical deterrents affect granivory in the reconstructed prairie. I hypothesized that granivores remove …
