Comparison of Torpedograss and Pickerelweed Susceptibility to Glyphosate
Torpedograss (Panicum repens L.) is one of the most invasive
exotic plants in aquatic systems. Repeat applications of
(N-phosphonomethyl) glycine (glyphosate) herbicides provide
limited control of torpedograss; unfortunately, glyphosate
often negatively impacts most non-target native species
that grow alongside the weed. This experiment studied the
effect of glyphosate on pickerelweed (Pontederia cordata L.), a native plant that shares habitats with torpedograss. Actively growing plants of torpedograss and pickerelweed were cultured in 8-liter containers and sprayed to wet with one of four rates of glyphosate: 0%, 0.75%, 1.0%, or 1.5%. Each treatment included a surfactant to aid in herbicide uptake and a surface dye to verify uniform application of the treatments. All herbicide treatments were applied with a backpack sprayer to intact plants and to cut stubble of both species. Four replicates were treated for each species-rategrowth combination during each of two experiment periods. Plant dry weights 8 weeks after herbicide application suggest that torpedograss was effectively controlled by the highest rate of glyphosate applied to cut stubble. Pickerelweed was unaffected when the highest rate of glyphosate was applied as a cut-and-spray treatment. These data suggest that a cut-and-spray application of a 1.5% solution of glyphosate may be an effective strategy to control torpedograss without deleteriously affecting pickerelweed.

From working-class origins to academia: community college women who have crossed the great class divide
There is a paucity of research about the experiences of women from working-class families who become faculty or administrators in higher education institutions. Most research and literature about the experiences of female faculty and administrators focus on those women who work in four-year college and university settings. This phenomenology focused on the experiences of nine working-class women who are faculty and administrators at a large, Midwestern, multi-campus community college. The participants shared their perceptions and experiences as children and adolescents in a working-class family, as students, as wives and mothers, and as community college professionals, and how these shaped their lives both personally and professionally.;This research illuminated the experiences of women whose lives bridged the chasm between working-class America and the doors of two-year colleges. Among the findings were the participants\u27 consistent commitment to working two and sometimes three jobs throughout their lives, and a common work ethic that has been a thread throughout their personal and professional lives. A reoccurring theme was the participants\u27 constant search and effort to establish different kinds of community throughout their lives. Their efforts to find supportive educators, peers, and colleagues during their early years, college experiences, and professional lives, is nothing short of remarkable. Their narratives give rise to the premise that community colleges should aim to work together to share innovations in student services, curriculum development, and professional development. Although community colleges are local institutions, their goals for developing human resources should be all-encompassing in scope. The participants in the study revealed that their pathways enabled them to empathize with, relate to, and encourage students. Therefore, community colleges should seek to develop programs and opportunities for faculty and administrators who are female. Investigations of needs, interests, and talents among working-class women who are faculty and administrators will do much to shape their career tracks, leadership styles, and resultant roles in community colleges
ES-SEN-TIAL
This thesis is in support of the exhibition entitled ES-SEN-TIAL on display in Tipton Gallery located in Downtown Johnson City from February 27, 2017 to March 10, 2017.
The exhibition is a presentation in fiber medium of the human impact on the landscape, specifically using the extractive industry of coal mining as example. This is accomplished through the use of digital imagery printed on textiles, hand and machine embroidery, and surface design techniques of dyeing and layering. This body of work reflects the artist’s interest in art activism and the utilization of photography, fiber arts, ideas and techniques, as creative process to formally explore the landscape
Can Neuroscience Help Predict Future Antisocial Behavior?
Part I of this Article reviews the tools currently available to predict antisocial behavior. Part II discusses legal precedent regarding the use of, and challenges to, various prediction methods. Part III introduces recent neuroscience work in this area and reviews two studies that have successfully used neuroimaging techniques to predict recidivism. Part IV discusses some criticisms that are commonly levied against the various prediction methods and highlights the disparity between the attitudes of the scientific and legal communities toward risk assessment generally and neuroscience specifically. Lastly, Part V explains why neuroscience methods will likely continue to help inform and, ideally, improve the tools we use to help assess, understand, and predict human behavior
