The New North: Patents And Knowledge Economy Analysis In Alaska, Salma Zbeed

Dissertations and Theses @ UNI

In the last few years, Alaska's economy suffered as world oil prices plunged to very low levels, and the analysts predicting that Alaska output will continue to dwindle in the years to come. As a result of Alaska's dependence on oil economy, the state now faces a budget deficit. Modern economic development theories suggest searching for ways to manage northern frontiers. Investment in a knowledge –based economy seems to be new one of the appealing alternatives, and investing the human capacities is necessary. There is enough evidence from both central and peripheral regions that geographic proximity between the people and …

Saving Local Communities Using Scrip Money To Fight The Great Depression In North Central Iowa, Bryan Carl Bjorklund

Dissertations and Theses @ UNI

In 1933, during the depths of the Great Depression, the Mason City Chamber of Commerce authorized the issuance of 10,000 yellow certificates with a face value of $1.00. This local effort to fight the economic disaster was represented in the unique certificates known as stamp scrip money. The overall goals of the program was to offer the unemployed work relief, build a road to further connect the city, experiment in the road building process using concrete macadam, and to stimulate local business all through the issuance of the 10,000 certificates.

The Programmatic Manipulation Of Planar Diagram Codes To Find An Upper Bound On The Bridge Index Of Prime Knots, Genevieve R. Johnson

Dissertations and Theses @ UNI

The “bridge index” of a knot is the least number of maximal overpasses taken over all diagrams of the knot. A naïve method to determine the bridge index of a knot is to perform Reidemeister moves on diagrams of the knot, and this method quickly becomes tedious to implement by hand. In this paper, we introduce a sequence of Reidemeister moves which we call a “drag the underpass” move and prove how planar diagram codes change as Reidemeister moves are performed. We then use these results to programatically perform Reidemeister moves using Python 2.7 to calculate an upper bound on …

Valproic Acid: A Neural Outgrowth Model For The Autism Spectrum Disorder, Hannah M. Bergan

Dissertations and Theses @ UNI

Autism spectrum disorder has been dramatically on the rise since the early 1990s, with one in forty-five children being diagnosed in 2014. It is known that contributing factors to autism spectrum disorder may have genetic and epigenetic origins, as well as environmental triggers. What is still unclear, however, is the impact of teratogenic drugs, consumed by the mother, have on a developing fetus in utero. How can they lead to the child developing autistic-like behaviors? The current study documents the effects of one teratogenic drug Valproic acid, a known histone deacetylase inhibitor. It establishes the role it plays on developing …

Using Blended Learning To Improve Undergraduate Introduction To Literature Courses: A Mixed Methods Approach, Julie Leigh Klein

Dissertations and Theses @ UNI

Blended learning is being used more and more in higher education. However, for humanities and other loosely content structured areas, blended learning can be challenging. It has generally been reserved for subject areas such as computer programing, mathematics, business, science, and statistics--courses where competence is commonly assessed by administering work on which performance is either right or wrong. Furthermore, agreement has not yet been reached on how to best incorporate the face-to-face and online teaching resources. This study examines one approach of implementing web-based instruction to improve undergraduate Introduction to Literature courses at a midsized Midwestern university.

This study was …

A Presidential Paradigm Shift: Changes In Presidential Rhetoric Regarding Cuba, Alyssa Chellan Dixon

Honors Program Theses

On March 22, 2016, United States President Obama and Cuban President Raúl Castro sat side-by-side in the Estadio Latinoamericano baseball stadium, watching the Tampa Bay Rays and the Cuban national team face off in a historic game. Such an event would have been unprecedented in the several decades prior to its occurrence. Indeed, though at the U.S.-Cuba game Obama and Raúl Castro were even as friendly to have participated in doing “the wave” together,ii relations between the U.S. and Cuban governments were anything but, even during the preceding U.S. presidency of George W. Bush.

The United States has had a …

Effect Of Disorder On The Magnetic And Electronic Structure Of A Prospective Spin-Gapless Semiconductor Mncrval, P. Kharel, J. Herran, Pavel Lukashev, Y. Jin, J. Waybright, S. Gilbert, B, Staten, P. Gray, S. Valloppilly, Y. Huh, D. J. Sellmyer

Faculty Work

Recent discovery of a new class of materials, spin-gapless semiconductors (SGS), has attracted considerable attention in the last few years, primarily due to potential applications in the emerging field of spin-based electronics (spintronics). Here, we investigate structural, electronic, and magnetic properties of one potential SGS compound, MnCrVAl, using various experimental and theoretical techniques. Our calculations show that this material exhibits ≈ 0.5 eV band gap for the majority-spin states, while for the minority-spin it is nearly gapless. The calculated magnetic moment for the completely ordered structure is 2.9 µ_B/f.u., which is different from our experimentally measured value of …
