Invasive Weeds, Wildfire, and Rancher Decision Making in the Great Basin

In this article, a numerical stochastic dynamic programming model (SDP) is developed to characterize the decision problem of a rancher operating on rangelands in northern Nevada that are affected by invasive annual grasses and wildfire. The model incorporates decisions about herd size management of a cow-calf operation and fuels treatment to reduce the size of rangeland wildfires. Currently, high transactions costs to obtain permits to implement land treatments on federally-owned rangelands appear to limit rancher involvement. The results of the model suggest that ranch income motives alone are likely insufficient for private ranchers to adopt preventative land treatments. The current treatment cost ($20 per acre at the minimum) appears to be prohibitively expensive relative to the benefits derived from the treatments under the low-productivity, semi-arid rangeland conditions.stochastic dynamic programming, cow-calf operation, rangeland, ecosystem, Livestock Production/Industries, Resource /Energy Economics and Policy,

College and Career Ready through Personalized Learning: Business and Industry Perspective of the Don Tyson School of Innovation

This qualitative research study describes perceptions of Northwest Arkansas’ business, industry and post-secondary institutions as to the Don Tyson School of Innovation (DTSOI) and its ability to prepare students for Northwest Arkansas’ college and career needs. Designated as one of the first schools of innovation in Arkansas through ACT 601 of 2013 by the Arkansas Department of Education (ADE), the DTSOI employs Science, Technology, Engineering, and Mathematics (STEM) in every aspect of curriculum. The DTSOI represents the first school in Arkansas to hold the distinction of holding both school of innovation status as well as being a public, district- conversion charter school. This model is the first in Arkansas to embrace a student-centered, time flexible, competency-based, blended, personalized learning experience. Students at SOI have the opportunity to attain their high school diplomas while also acquiring professional industry credentials, internship experience, early college experience, and even an Associate’s Degree. In addition to new curricular and instructional models, the DTSOI offers students deeper experiences in developing “soft or executive skills” deemed by Northwest Arkansas business, industry and post-secondary members as valuable employment traits. Created with combined effort from post-secondary educational partners, local businesses, and industry, DTSOI includes executive skills in every aspect of curriculum to promote student career readiness. Currently in the fourth year of operation (2017-2018), the program is predicated on being agile enough to both prepare students to excel in post-secondary education and career readiness, adapting as industry needs change. In this study, stakeholders were asked whether they see evidence of SOI’s success, based on their knowledge and perception of the school programs and interactions with DTSOI students

Television Histories: Shaping Collective Memory in the Media Age

From Ken Burns’s documentaries to historical dramas such as Roots, from A&E’s Biography series to CNN, television has become the primary source for historical information for tens of millions of Americans today. Why has television become such a respected authority? What falsehoods enter our collective memory as truths? How is one to know what is real and what is imagined—or ignored—by producers, directors, or writers? Gary Edgerton and Peter Rollins have collected a group of essays that answer these and many other questions. The contributors examine the full spectrum of historical genres, but also institutions such as the History Channel and production histories of such series as The Jack Benny Show, which ran for fifteen years. The authors explore the tensions between popular history and professional history, and the tendency of some academics to declare the past “off limits” to nonscholars. Several of them point to the tendency for television histories to embed current concerns and priorities within the past, as in such popular shows as Quantum Leap and Dr. Quinn, Medicine Woman. The result is an insightful portrayal of the power television possesses to influence our culture. Winner of the 2001 Ray and Pat Browne Award for Outstanding Textbook given by the Popular Culture Association Offers much food for thought in this highly visual age. —Alliance (OH) Review As an example of well-reasoned, original research, Television Histories makes an important contribution to the study of the medium. —Anthony Slide, Classic Images This book is even more timely and provocative because much of the material discussed is being rebroadcast now that digital television is opening even more new channels. —Choice An engrossing collection that slides the thorny subject of television, history, and memory under a microscope. . . . Digs deep into a contemporary phenomenon, and its many conclusions are right on target. —Film & History Helps those of us who care about history think more clearly about how television can shape historical thinking among our friends, neighbors, and students. —Florida Historical Quarterly Television Histories, a pioneer work, weaves an inspired and informed interdisciplinary analysis of television and history. The chapters are enlightening, readable, and entertaining; the editors and the authors have produced a work that enriches and strengthens the study of film and history. —Michael Schoenecke The stuff serious thinkers in a media age should read, mark and remember. —Rockland (ME) Courier-Gazette An insightful and important addition to the literature that sheds light on an often controversial subject for professional historians. —Southern Historian Most of the essays are likely to be of considerable value to any attentive student of television. —Television Quarterly Working from the thesis that people learn about history through television more than any other medium, Edgerton and Rollins look at what TV subliminally teaches us by what is shows and does not show. —Varietyhttps://uknowledge.uky.edu/upk_film_and_media_studies/1020/thumbnail.jp

Rangeland Fires and Cheatgrass: Values at Risk and Support for Preservation

The high desert sagebrush ecosystems of the Great Basin evolved with fire. However, the introduction of cheatgrass (t. bromus), a highly flammable invasive annual grass, has contributed to the increased intensity and frequency of wildfires we have seen in recent years. Cheatgrass-fueled fires often kill native perennials, which creates openings for further cheatgrass expansion. Winters with more moisture than usual result in more cheatgrass and increased fire risk. Over time the result is ever larger areas dominated by cheatgrass and other invasive weeds that burn with greater frequency, and increasingly severe fire seasons

CD80 Expressed by CD8+ T Cells Contributes to PD-L1-Induced Apoptosis of Activated CD8+ T Cells

Tumor cells are capable of limiting antitumor CD8+ T cell responses through their cell surface expression of PD-L1. In addition to PD-1 expressed by CD8+ T cells, PD-L1 also binds to CD80 expressed by CD8+ T cells. The influence of the PD-L1/CD80 interaction on CD8+ T cell function has not been fully characterized, so we sought to investigate the impact of the PD-L1/CD80 interaction on PD-L1-induced apoptosis of activated CD8+ T cells. We found that CD8+ T cells that lacked CD80 expression got activated to the same extent as wild-type CD8+ T cells, but when cultured with anti-CD3 and PD-L1/Fc protein, activated CD8+ T cells that lacked CD80 expression survived better than activated wild-type CD8+ T cells. These findings indicate that PD-L1 induces apoptosis in activated CD8+ T cells in part by signaling through CD80. Thus, in the design and implementation of checkpoint blockade therapies that target PD-L1, it is essential that both binding partners for PD-L1, PD-1, and CD80 are considered
