Quasi-Experimental Evaluation Of Undergraduate Learning In A Multidimensional Wellness Course, Kristi Leonard

Dissertations and Theses @ UNI

Introductory wellness courses are common among American institutions of higher education. These courses are typically of a unidimensional approach, focusing on just the physical component of wellness. Some wellness educators would argue that a multidimensional approach is a richer and more valuable learning experience. Furthermore, technology has played a larger role in wellness education, as it is being created, developed, and implemented into the field. Therefore, college wellness educators and curriculum designers need to determine the implications for both online and face-to-face instructional methods in their execution of teaching the holistic concept of wellness to their students.

The purpose of …

The Difference Connection Makes : Roles The Middle School Teacher Plays In Changing Adolescent Girls’ Lives, Denise M. Pralle

Dissertations and Theses @ UNI

Within the classroom setting, 'fitting in' can be a very difficult matter for both students as well as teachers. A sense of community and respect for others, which prevails in the elementary grades, seems more subdued among middle-schoolers as competition and the struggle for independence becomes part of the hidden curriculum. Adolescent girls especially struggle to imitate what developmental psychologists suggest is necessary at this age: independence and disconnection from others. However, disconnection at this stage of development may partially account for the competition, disrespect of others, and loss of morality in and out of the classroom. Connected classroom teachers …

This legislation affected aspects of English, science, and mathematics. The most significant change resulted in the increase of mathematics study from two years of mandatory study to three years in order to graduate. Any district that did not already require students to take three years had to decide how to react to this new requirement. This quantitative research study was designed to examine what effects this change had …

Perceptions Of Dimensions Of Service Quality And Recreational Benefits In Collegiate Recreational Sports Programs, Christopher Berne Denison

Dissertations and Theses @ UNI

An enduring and essential element of collegiate recreational sports programs is an emphasis on providing high quality, high impact programs and services. In addition, participants in collegiate recreation settings have an expectation to receive benefits as a result of their participation. If recreational sport programs cannot meet the expectations of participants in their pursuit of these benefits, continued participation is unlikely. As collegiate recreational professionals work to continually improve their programs and services, they should also understand the needs and wants of their participants. Understanding what participant needs and wants are should allow leisure service providers to improve the programs …

Recalcitrant Arguments, Kiranjeet Kaur Dhillon

Dissertations and Theses @ UNI

On January 26, 2011, Reuters photojournalist Amr Abdallah Dalsh took an image of a unknown veiled woman gesturing at Dalsh and his camera. Using TinEye, a reverse image search engine, I found that 86 circulations and 22 recirculations of the photo were primarily in the United States. US graphic artist Nick Bygon created one of the recirculations, which primarily appeared on US blogs. The photo achieved this level of circulation in the US because it is consistent with, and therefore legible within the symbolic language, of the liberal democratic order.

The Texas Heart Institute Journal

Arterial remodeling, an early change of atherosclerosis, can cause dilated arterial diameter. We measured coronary artery diameter with use of noncontrast 64-slice multidetector computed tomography (MDCT), and studied its association with coronary artery calcium levels and traditional coronary risk factors.

We included 140 patients from the ACCURACY trial whose noncontrast MDCT images showed measurable coronary arteries. Using 3 measurements of left main coronary artery (LMCA) and right coronary artery (RCA) diameters within 3 mm of the ostium, we associated the results with traditional coronary risk factors and calcium scores.

The prevalence of LMCA and RCA calcium was 22% and 51%, …

Foreign Affairs Federalism: A Revisionist Approach, Daniel Abebe, Aziz Z. Huq

Faculty Scholarship

In April 2010, the Arizona legislature enacted the Support Our Law Enforcement and Safe Neighborhoods Act. Commonly known as SB 1070, the law created a slate of new criminal offenses and arrest powers covering aliens within Arizona's borders. SB 1070 proved divisive. It inspired copycat legislation in several states, provoked sharp criticism from the legal academy, and – most relevant here – catalyzed a lawsuit by the U.S. Department of Justice seeking a preliminary injunction against the state law on the ground that it was preempted by federal law. Initially, the federal government's litigation prospects seemed dim. One term before …
