Alaskan prospects: Using the mining prospector image in early twentieth-century Alaska

Seger, Christina Rabe The University of Arizona 2001 해외박사(DDOD)

In the first two decades of twentieth-century Alaska, various groups portrayed the mining prospector as a central Alaskan figure despite the fact that the actual prospector was neither the image maker nor always part of the desired end. Political and economic interests and policies were promoted aggressively by rhetorical arguments; in Alaska, these arguments used the ideals found in the nineteenth-century prospector image as an ideological cover and a material means for early twentieth-century economic and political goals of industrial growth and regional development. The prospector was one of the most complex of Western characters, a prototype that was a product of American cultural, economic, legal and political ideals and notions about the individual and individualism. The mining industry, federal agencies overseeing Alaskan mining, and Alaskan promoters all used prospector images to entice mineral seekers to Alaska, but they also worked to direct prospectors in material ways to ultimately aid their own industrial-based goals of Alaskan growth and settlement. Actual Alaskan prospectors could not fully live up to their images. They faced many challenges in Alaska, but were able, through hard effort, to achieve a limited self-sufficiency. Prospector images were also at center-stage of ideological and rhetorical debates to determine land use policy of Alaskan coal lands, despite the simple fact that actual mineral seekers had little to do with coal mining development. Prospector images also carried political meanings in the struggle for Alaskan home rule. Using this fluid iconic figure did have material consequences, although in the end the political economy had greater influence in Alaskan development.

Effects of dietary fat and protein from corn coproducts on growth, carcass characteristics, ruminal metabolism, and genomic regulation of marbling development in early-weaned beef cattle

Segers, Jacob R University of Illinois at Urbana-Champaign 2013 해외박사(DDOD)

Four experiments were conducted to evaluate the effects of dietary fat and protein from corn coproducts on growth, carcass characteristics, ruminal metabolism, methane production, and transcriptional regulation of marbling. In Exp. 1, crossbred heifers (n = 150) and steers (n = 100) were used to evaluate 1 of 5 growing diets in a 2 x 2 + 1 factorial arrangement of treatments: 1) corn-based control; 2) low fat, low protein coproduct blend; 3) high fat, low protein coproduct blend; 4) low fat, high protein coproduct blend; 5) high fat, high protein coproduct blend. Low protein and low fat diets were formulated to be isonitrogenous with similar fat content to control (16.0% CP, 3.0% fat), and high protein and high fat diets were formulated to be 20.0% CP and 5.0% fat respectively. Calves were weaned at 90 d, blocked by sex and then by weight into 25 pens (10 hd/pen). The objective of this experiment was to determine if differing concentrations of protein and fat in coproduct-based growing diets of early-weaned calves affect feedlot performance and carcass composition. Calves were fed experimental diets for 112 d and then acclimated to a common feedlot diet for an additional 112 d. Body weight, hip height (HH), and ultrasound data were collected at the end of each 112d feeding phase. Carcass data included HCW, LM area (LMA), 12th rib back fat (BF), marbling score (MS), KPH, and USDA QG. In Exp. 2, Longissimus lumborum of thirty crossbred calves (Age = 95 +/- 1.7 d; BW = 179 +/- 18 kg) were fed diets from experiment 1. Biopsies were collected from the LM at 0, 112, and 224 d for transcriptional analysis via RT-qPCR of 14 genes associated with adipogenesis and lipogenesis within the muscle. The objective of this experiment was to examine the effect of dietary fat and protein concentration on serum concentrations of leptin, IgF1 and growth hormone, and gene expression of fourteen genes that regulate lipid metabolism and adipogenesis. Serum was collected at d 0, 112, and 224 and analyzed for leptin, insulin-like growth factor 1, and growth hormone concentration. Data were analyzed to ascertain the effects of protein level, fat level, time, and their interactions on gene expression and blood metabolite concentration. Carcasses from cattle fed control during the growing phase tended (P = 0.09) to have higher marbling scores while other carcass parameters were not different (P ? 0.13). These data indicate that feeding differing levels of dietary fat and protein during the growing phase does affect intramuscular adipogenesis at the transcriptional level, but differences in gene expression were not sufficient to affect carcass quality among cattle fed coproducts. In Exp. 3, 40 steers (age = 134 +/- 3 d; BW = 185 +/- 11 kg) were randomly allotted to 1 of 5 dietary treatments: 1) corn-based control (CNT), 2) 0% corn distillers solubles (CDS), 3) 10% CDS, 4) 19% CDS, or 5) 27% CDS. Diets 2--5 included coproducts (corn gluten feed and soybean hulls) and were formulated to achieve fat concentrations of 3, 5, 7, and 9%, respectively. Diets were fed once daily for 106 d growing phase. All steers were fed a corn-based diet from d 107 to 196 (finishing phase). Contrasts were used to examine a) the difference between CNT and 10% CDS; b) linear and quadratic effects of CDS inclusion. This research provides insight into the effects of elevated protein and fat from corn coproducts on the molecular regulation of intramuscular fat development. Feeding differing levels of dietary fat and protein during the growing phase does affect intramuscular adipogenesis at the transcriptional level, but differences in gene expression were not sufficient to affect carcass quality among cattle fed coproducts in our small subset. However, coproducts with no corn fed during the growing phase resulted in carcasses with similar marbling scores to those fed corn-based growing diets suggesting that starch may not be necessary to produce high quality carcasses from early-weaned calves. Additionally, These data indicate a difference in the behavior of fat from CDS in the rumen compared to other fat supplements such as corn oil. Increased performance with increased CDS inclusion and the lack of adverse effects on ruminal metabolism and carcass traits make CDS a viable option for beef cattle diets.

Mislaid landscapes: Environmental change and interstitial terrain in Calvino, Pasolini, Celati, Vinci and Cipri & Maresco

Seger, Monica The University of Wisconsin - Madison 2010 해외박사(DDOD)

This dissertation is a study of landscape representation in twentieth and twenty-first century Italian texts. It operates primarily from the fields of environmental criticism and landscape studies, while also considering the work of cultural critics such as Julia Kristeva and Giorgio Agamben. This study aims to examine the ways in which modern and contemporary Italian voices approach a natural landscape forever altered by post-war industrial culture, land that is home to what is often referred to as second nature. After an introduction detailing the socio-historical framework of post World War I1 Italy in relationship to environment, it considers a series of individual voices. The first chapter studies two of Italo Calvino's novellas, La speculazione ediliza (1957) and La nuvola di smog (1959), both of which question an interest in expansion during Italy's early economic boom years. The second is dedicated to Pier Paolo Pasolini's film work, focusing in particular on films such as Accattone (1961), set in Rome's bare periphery. The third chapter then rams to more recent times with Gianni Celati's meanderings along the banks of the polluted Po valley in his first person book Verso la foce (1989). From there the focus moves to Simona Vinci, a younger contemporary author, to trace the growth of an ecological awareness throughout her career since the mid-1990s. Special attention is paid to her 2007 novel Strada Provinciale Tre . The final chapter returns to film with the directorial team Daniele Cipri and Franco Maresco. Their Palermo based shorts and feature-length films, such as A memoria (1995) and Toto the visse due volte (1996) depict a complete merger of realms natural and cultural just as they challenge notions of health, beauty and (pro)creation in regards to both man and land. While all of these texts differ greatly in style, they are ultimately united in reworking traditional definitions of nature and landscape as they question just what sorts of landscape are, or are not, ascribed positive value in a society.

Literal intergroup contact: Embodied relational cues and the reduction of intergroup bias

Seger, Charles R Indiana University 2010 해외박사(DDOD)

Existing evidence shows that a brief, casual interpersonal touch results in positive behavior toward the toucher. Theoretically this effect arises because touch is an embodied cue to friendship or closeness, as demonstrated by its role in attachment and relationship development. According to research on intergroup contact, feelings of friendship toward an individual outgroup member reduce prejudice toward the entire social group. This research examined whether the effects of touch extend beyond the toucher as an individual, to influence feelings about that individual's social group. The initial study demonstrates that interpersonal touch decreases implicit, though not explicit, prejudice toward the toucher's social group (African Americans). The second study replicated this effect for African American and Asian touchers, while also demonstrating a novel effect: touch increases participants' general tendency to report empathic emotions in response to scenarios in which others were treated negatively. In the third study, half of the participants formed a negative attitude toward the African American toucher before the touch. Although touch did not affect implicit prejudice toward African Americans, touch did buffer the effects of a negatively evaluated toucher on implicit evaluations of the group. An implicit measure of self-esteem was unrelated to the implicit attitude measure. Throughout these studies, implicit evaluations of other social groups (e.g., Caucasians) were not affected by touch. Not only are these results unique in demonstrating that the effects of interpersonal touch can extend beyond the toucher to an entire social group, they suggest that the these effects of touch are automatic and occur outside of conscious awareness.

Role of Elementary School Leaders in Special Education Decisions

Seger, Christa Mae Montana State University ProQuest Dissertations & 2020 해외박사(DDOD)

This study was designed to gain an understanding of tasks elementary building leaders are personally involved with special education building tasks and identify building leaders who self-identify as highly engaged in special education. Instructional leaders must have a full understanding of educational practices as they relate to special education. Building level leaders are asked to perform many different tasks daily. With over 7.0 million students identified as needing special education services, many building leaders struggle with their knowledge of special education and their role. Many Educational Leadership programs do not require a building leader to be educated specifically in the area of special education practices and law thus creating a disconnect in instructional leadership. A case study design was used in answering the four research questions. A survey, Questionnaire on the Special Education Roles and Functions of the School District and/or Building Level Administrator, was administered to elementary building level leaders in one western urban school district in Denver, Colorado. Once quantitative data was collected and analyzed, a qualitative phase using interviews with self-identified highly engaged elementary leaders was conducted. The findings suggest principals who are highly engaged in special education tasks have an understanding of their role and what strategies are needed to be an effective special education instructional leader. These strategies include being (a) collaborative, (b) accountable, and (c) being in a position to create trusting, authentic relationships with stakeholders. It is important for building leaders to have appropriate training to (a) access information through on-the-job training, (b) to prevent a lack of knowledge in IDEA tasks, and (c) be held accountable for ensuring special education programs are adequately supported in their building.
