Height Data
No full textThese are height measurement data for female, individually-known African elephants in the Samburu and Buffalo Springs National Reserves. These data were used in the manuscript "Orphaning stunts growth in African Elephants", currently under review. The first Excel worksheet is titled "GW.growth.curve". It shows the median of the height measurements taken from an elephant on a single date by author George Wittemyer. These medians were used to create a von Bertalanffy growth curve upon which we structured the Bayesian analysis that addressed our main hypotheses. The second worksheet titled "All.data" shows all measurements taken by either author. The third worksheet shows a summary of author Jenna Parker's measurements, including which individuals were not included in the main analysis because we are unsure of their exact birthdate
Access to inaccessible 5-membered heteroarynes
No full textUniversity of Minnesota Ph.D. dissertation. June 2024. Major: Chemistry. Advisor: Courtney Roberts. 1 computer file (PDF); xxxii, 401 pages.Aryne chemistry is a powerful method for accessing difunctionalized products. Therefore, these intermediates have promising applications in discovery chemistry as they allow making iterative structural changes to targets using a common intermediate which can glean important insights on structure function relationships. Arynes have seen promising utility in the synthesis of heterocycles which are prevalent in the pharmaceutical industry, however, the field has been limited by the scope of heteroarynes which can be accessed using existing methods. Five-membered N- and O-heteroarynes are predicted to be “inaccessible” due to ring strain; yet heteroaryne intermediates would represent a promising common intermediate for installing heterocycles into target compounds. Herein we disclose the first examples of accessing 7-aza-2,3-indolynes and other N-heteroarynes using Ni-complexes. Work is underway to insights into the transmetallation step which is key for aryne formation. Additionally, work is underway to apply these complexes in difunctionalization reactions that would allow for rapid synthesis of heterocyclic compound libraries to be utilized in discovery chemistry.Humke, Jenna.

Virilization and Enlarged Ovaries in a Postmenopausal Woman
No full textA patient with postmenopausal bleeding and virilization was found to have bilaterally enlarged ovaries with a yellow cut surface. Histology revealed cortical stromal hyperplasia with stromal hyperthecosis. This hyperplastic condition should not be mistaken for an ovarian neoplasm.Peer reviewe
Welfare: as American as baseball
No full textThere are great many things that Americans can truly claim as their own, welfare is one of them. Welfare has become and American staple that rivals fords and baseball. America has created an ideology that is both accepting and allowing of consumerism and inefficiency, when it comes to fiscal responsibility. Americans idealize capitalism and also charity work, causing a collision of ideas politically and socially. The allowance for both has brought on two schools of thought. In one school, we as a culture press for innovation and poise in society, in the other we see classes of people who are constantly behind the economical curve. As they have come to coexist, the principles of our society have learned to accept that some people will accelerate and others will struggle with assistance of the government. Welfare has become cyclical (from adult to child, and then to that child as an adult) because we as a culture accept that welfare exists through legislation, ideals and in the business sector. Welfare has become a truly American innovation, spreading, and expanding, creating an entire genre of social status. Welfare is an American staple because even though we as a culture recognize its continued presence, we have yet to understand it. Comprehensive approaches to both education and the dolling out of American tax dollars would correct and also alleviate the fiscal beating that we as a society experience, and also remove the stigma applied to welfare recipients.M.A.L.S.Includes summaryIncludes bibliographical references (p. 52)by Jenna L.

From Wunderkammern to Kinect: The Creation of 'Shadow Worlds'
No full textThis paper focuses on two projects, Still Life No. 1 and Shadow Worlds | Writers' Rooms [Brontë Parsonage], to reveal the creative approaches the authors take to site, technology, and the self in their production of shadow worlds as sites of wonder. Informed by the uncanny (re-animation and the double) and an interest in the limen (thresholds in the real and virtual realms), the projects explore white light and infrared digital 3D scanning technologies as tools for capture and transformation. The authors will discuss how they suture the past with the present and ways that light slips secretly between us, revealing other realms
Bodies of evidence: the image, the flesh, and the modern crisis of the human
No full textBodies of Evidence is a study of the transnational optics of anti-blackness across German and U.S. settler colonial projects, with a particular attention to the afterlives of visual discourses in present-day politics and memory. This dissertation analyzes case studies from the U.S., Germany, and German South West Africa, what is present-day Namibia, to track the trace of settler colonial and racial ideologies across seemingly discrete and ruptural violences. Rather than continue to treat these histories and archives as distinct or hierarchical instances of violence, I argue for the importance of interpreting them as part of a broader, uninterrupted narrative. Bodies of Evidence adopts a transnational scope that places settler colonial violence—including the Herero and Nama genocide in German South West Africa—alongside European genocide, framing these events as part of the same ideological and scopic regime. My interdisciplinary analysis builds upon critical race theory, critical visual studies, postcolonial and Black feminist scholarship, museum studies, biological anthropology, among other interdisciplinary and theoretical threads. I critically interpret visual and material evidence with a methodological emphasis on framing the positionality of the viewer in relation to questions about the gaze and modes of looking. Thinking through the looped gaze, parallactic witnessing, and the ethics of looking, I argue that we can transform the act of looking if we understand how the circulation and containment of colonial violences continue to shape ways of seeing.Ph.D.Includes bibliographical referencesby Jenna R.

Development of transition-metal catalyzed cross-coupling reactions involving amide electrophiles with heterocyclic nucleophiles
No full textThere are many technological challenges that face society today, one of which is the ability to develop precise control over chemical reactions. Many of the high-value molecules used as pharmaceuticals, agrochemicals, and important materials must be made using synthetic techniques. These industries require efficient and cost-effective methods to synthesize their products. Cross-coupling reactions are one such method that have become heavily used. Although amides are an extremely prevalent and important functional group, there has been little investigation into performing these cross-coupling reactions with amide as coupling partners. Thus, it remains a challenge in the field of organic synthesis. We have demonstrated reactivity for cross-coupling reactions with amide electrophiles and heterocycle nucleophiles in order to generate ketone products containing heterocyclic units. By targeting these medicinally-important heterocyclic compounds, this research will be useful in making important target compounds more accessible while also developing a new class of electrophiles to use in cross-coupling reactions.</p
