Newspapers as a Form of Settler Colonialism: An Examination of the Dakota Access Pipeline Protest and American Indian Representation in Indigenous, State, and National News

Beckermann, Kay Marie January 2019 (has links)
Settler colonial history underlies much of contemporary industry, including the extraction and transportation of crude oil. It presents itself in a variety of contexts; however, this disquisition applies a traditional Marxist perspective to examine how settler colonialism is present in news media representation of American Indian activists during the Dakota Access Pipeline protest. Rather than focus on the benefit of using colonized labor for financial gain, this disquisition pushes Marxism into settler colonialism in which the goal is to eliminate the Indigenous and continue to widen the gap between social classes. This research is important for two reasons. First, the media are powerful, making it the perfect vehicle to disseminate inaccurate representations of American Indians. These incorrect representations come in the form of media frames that created an altered reality for news audiences. Second, the term settler colonialism, in particular its relationship with American Indian protest, has been little studied in the American field of communication. A comparative qualitative content analysis was applied to media artifacts from the protest that occurred in North Dakota. Artifacts were discovered using a constructed week approach of two online versions of print publications—the Bismarck (ND) Tribune and the New York Times—and one digital only news site, Indian Country Today. One hundred twenty four artifacts were examined in total. Five dominant frames emerged from the analysis: blame, cultural value, water, American Indian stereotypes, and confrontation. These frames were considered dominant due to the number of coded excerpts that appeared in at least 20% of the artifacts. The frames either contribute to or resist settler colonialism based on the publication in which it appears. The Bismarck Tribune contributed the most to settler colonialism; the New York Times neither rejected nor acknowledged it while Indian Country Today resisted through recognition of America’s settler colonial past, sovereignty, and government-directed violence. The implication of this research is that elimination of the American Indian is ubiquitous in American news media. The mainstream media contributes to widening the gap between social classes, ensuring the dominant class stays in power and Indigenous issues are ignored.

The Coalescence of Education and Criminal Justice in the United States: The School-Prison Nexus and the Prison-Industrial Complex in a Capitalist Society

January 2020 (has links)
abstract: The education and criminal justice systems have developed in relation to one another, intersected through specific events, policies, practices, and discourses that have ultimately shaped the experiences and lives of children of color. Racism, white supremacy, and oppression are foundational to the United States and evident in all systems, structures, and institutions. Exploring the various contexts in which the education and criminal justice systems have developed illuminates their coalescence in contemporary United States society and more specifically, in public schools. Public schools now operate under discipline regimes that criminalize the behavior of Black and Brown children through exclusionary practices and zero-tolerance policies, surveillance and security measures, and school police. Children of color must navigate complex and interlocking systems of power in schools and the broader society that serve to criminalize, control, and incapacitate youth, effectively cementing a relationship between schools and prisons. Describing these complex and interlocking systems of power that exclude children from schools and force them into the criminal justice system as the “school-to-prison pipeline” is increasingly insufficient. The “school-prison nexus” more accurately and completely embodies the relationship between education, incarceration, and the political economy. In the United States, where capitalism reigns, the school-prison nexus serves as an economic imperative to further fuel the political economy, neoliberal globalization, and the prison-industrial complex. In both the education and criminal justice systems, Black and Brown children are commodified and exploited through the school-prison nexus as a mechanism to expand free-market capitalism. / Dissertation/Thesis / Masters Thesis Social and Cultural Pedagogy 2020

Industry-Situated STEM Labs: A Case Study of a Novel Application

William H Walls (9745313) 18 December 2020 (has links)
Abstract: The purpose of this research was to understand: (1) the influence that an industry-situated STEM lab experience has on students’ (ages 10-18) perceptions of careers in manufacturing, and (2) the challenges and opportunities that this space presents. To answer these questions, this study analyzed participant pre- and post-draw a manufacturer tests as well as manufacturing career perception surveys that included Likert-scale items and open response questions. Along with these data sources, five semi-structured interviews were conducted with industry stakeholders in order to understand the conception and operation of the STEM lab, as well identify any challenges or opportunities to improve or replicate success for other industries. From there, the data were analyzed through thematic coding for the drawings, open-response questions, and interviews, and a Mann-Whitney U test was performed on the survey results in order to look for general shifts in responses to specific questions from before to after the STEM lab experience. The results gained from the three different data collection techniques were looked at in aggregate and used to triangulate specific understandings, questions, and recommendations. The results confirmed a lack of students’ awareness and understanding of manufacturing, misperceptions surrounding the careers within, and a disconnect between industry needs and educational output. Along with the data, literature on vocational psychology supports the need for students to participate in authentic learning opportunities to build self-efficacy and form more accurate outcome expectations with regards to future career selection. However, the data did reveal that the industry-situated STEM lab experience likely led the participants to an improved understanding of the manufacturing ecosystem and provided an opportunity for local educators to engage with industry. While this research looked at a novel application of a STEM lab and highlighted its influence on students’ perceptions of manufacturing careers, there is obviously no “silver bullet” for fixing the talent pipeline for manufacturing and continuous work in this area needs to be done.

Data Analytics of Energy Data

Havo, Oskar January 2022 (has links)
The thesis concerns mainly the construction of a pipeline that enables the analyzing,visualizing, and forecasting of time-series data in an intuitive and streamlined process.The main data set consists of four measurements: purchased heating, purchasedelectricity, and purchased cold water from select buildings at the Lule ̊a Universityof Technology campus as well as the outside temperature of the campus. This isused to establish a proof of concept, demonstrating the validity of this pipeline andits subsystems. Using this pipeline you are able to upload data, visualize data andanalyze data online and also create future forecasts of these measurements which arealso displayed online.As the global demand for energy efficiency increases, tools, like this one, is moreimportant than ever in order to give the decision-makers more insight. In the caseof the campus buildings, you might be able to more easily identify anomalous valueswhich point to some oversight that can then be amended. For instance, if two identicalbuildings exist and one of them consumes 50% more heating, you can conclude thata problem exists and now you know where the problem lies so you can amend theissue.Forecasting future consumption is also helpful since it would allow you to reducethe purchasing of fossil fuels, such as gas, which is the case at La Trobe Universityin Melbourne. Using forecasting they can better predict how much gas they need topurchase and when the peak consumption hours are so that they can adjust their solarproduction accordingly. Thus, forecasting future consumption can further reduce theglobal need and impact of fossil fuels.To conclude, this pipeline can be used as a tool to reduce the environmental impactof the Lule ̊a University of Technology campus buildings. The pipeline can then beapplied to other areas to help them solve their problems. Some of the findings ofthis thesis include comparisons of common forecasting algorithms and the benefits ofusing weekday/weekend models.In the future, this might also inspire others to make similar projects, just like LaTrobe University inspired us at the Lule ̊a University of Technology.
