Not Our Problem: Ingroup Glorification Facilitates Moral Disengagement And Exclusion, Matthew Gunderson

Dissertations and Theses @ UNI

The present study examined how ingroup/outgroup identification and harm predict cognitive restructuring and the shifting of blame. Drawing on Moral Disengagement Theory (Bandura, 1999), which holds that individuals create a new version of reality that allows them to violate their moral beliefs, I hypothesized that implicating the ingroup, lower levels of perceived harm, and higher ingroup glorification would result in more moral disengagement. Integrating Moral Disengagement Theory with Moral Exclusion Theory (Opotow, 1990), I further hypothesized that moral exclusion—the removal of others from the moral community—would also be greater. 422 participants recruited over Prolific read a modified news article about …

Students Vs. Suspects: A Qualitative Examination Of Stereotype Threat And The Impact On Behavior Of Black Males, Ryan J. Williamson

Dissertations and Theses @ UNI

This qualitative study focused on the impact of stereotype threat on the behavior of black males in the educational system. Black males currently involved in the juvenile justice system were interviewed about their lived experiences in the educational system. The literature surrounding stereotype threat focuses on academic achievement and performance. It provides spaces in the potential of stereotype threat impacting behavior.

Stereotype threat argues that individuals will confirm a self-characteristic which supports a negative stereotype associated with a specific group within society (Spencer et al., 2016). In theory, people will underperform based on a preconceived notion of failure. If a …

The New Independents: A Historical Analysis Of Webcomics And Webtoon, Leonal A. Sepúlveda S.

Dissertations and Theses @ UNI

Webcomics have now existed as a form of graphic literature for slightly over thirty years, evolving along with computer technology and in turn reflecting the changes in culture, style and preferences for both independent artists on the Internet and their audiences. The evolution of the webcomic illustrates how the changing trends in technology and profit interests shape stylistic and narrative sensibilities. In turn, the offshoot medium of webtoons, whose history parallels the webcomic directly, illustrates the way the presentday independent webcomic sphere is shaped by the demands of contents platforms that demand its creatives constantly produce content to maintain active …

"Land Of The Silver Birch": Environmental Attitudes And Place-Making In A Northern Minnesota Boy Scout Camp, 1960-1975, John Mark Fretham

Dissertations and Theses @ UNI

In 1959, leaders of the Minnesota Valley Council, BSA (headquartered in Mankato, MN) began making plans to create a new Boy Scout camp to replace their recently built camp in Southern Minnesota. The previous fifteen years of the post-World War II era had produced significant shifts in ideas about wilderness, what constituted quality outdoor recreation, growing anxiety about masculinity in the Cold War era, and expansion of the promotion and adoption of a North Woods tourist culture. These changes helped lead the council to begin looking for a site to create a new Boy Scout camp and build Camp Cuyuna …

Media Framing Of Marriage Practices In Afghanistan, Hakima Afzaly

Dissertations and Theses @ UNI

Culturally, in Afghanistan, marriage is given much importance and seen as something that completes life. Through this study, I analyze how marriage practices, such as dowry (Mahr), bride price, and the “virginity ritual,” are described in newspapers and magazines of Afghanistan. In particular, I explore how the popular press, such as 8 Sobh and Khama Press in Afghanistan frame their discussion of marriage practices. The findings from this analysis reveal that newspapers and magazines of Afghanistan frame marriage as an economic issue and a major focus of the articles is on the financial pressure on poor families due to the …

Mandhar Smart Application For The Visual Pollution In Muhaisnah-2 Area – Dubai Uae, Hamda Mohamed Alharmoudi

Theses

People naturally love beauty, beautiful views, and a beautiful environment. Beauty is the human eye that makes him happy and brings pleasure to his heart. If sport feeds the body and science feeds the mind, then beauty feeds the soul and the mind, all the beauty around us feeds the brain that has a positive impact on human life, and the distortion that we encounter in our life has a negative impact on us. Therefore, visual pollution is defined as, everything that is inconsistent with the beauty of the environment that surrounds us which create a harmful change for the …

Frameless-Finding And Refining A Sampling Frame For Surveying Recreational Fisheries: Lessons From Estimating Swedish Harvest Of Western Baltic Cod, Hege Sande, Nuno Prista, Annica De Groote, Michele Casini, Cynthia Jones, Andreas Sundelöf

OES Faculty Publications

To achieve sustainable fisheries, advice to management should be based on reliable science and unbiased data. Attaining quality data (i.e. precise and unbiased) on recreational fishing can be challenging, particularly when prior knowledge of the sector is limited and a proper sample frame of recreational fishers or vessels does not exist. In this study, a registry of access points was constructed for the Swedish south–west coast and used as a spatial sample frame in determining both effort and catches of the private boat fishery. Sampling dates, times for sampling, and access points visited were selected using probabilistic methods, ensuring unbiased …

Subsurface Eddy Facilitates Retention Of Simulated Diel Vertical Migrators In A Biological Hotspot, K. Hudson, M. J. Oliver, J. Kohut, J. H. Cohen, Michael S. Dinniman, John M. Klinck, C. S. Reiss, G. R. Cutter, H. Statscewich, K. S. Bernard, W. Fraser

OES Faculty Publications

Diel vertical migration (DVM) is common in zooplankton populations worldwide. Every day, zooplankton leave the productive surface ocean and migrate to deepwater to avoid visual predators and return to the surface at night to feed. This behavior may also help retain migrating zooplankton in biological hotspots. Compared to fast and variable surface currents, deep ocean currents are sluggish, and can be more consistent. The time spent in the subsurface layer is driven by day length and the depth of the surface mixed layer. A subsurface, recirculating eddy has recently been described in Palmer Deep Canyon (PDC), a submarine canyon in …

OES Faculty Publications

The mass of well-preserved calcite in planktonic foraminifera shells provides an indication of the calcification potential of the surface ocean. Here we report the shell weight of 8 different abundant planktonic foraminifera species from a set of core-top sediments along the Mid-Atlantic Ridge. The analyses showed that near the equator, foraminifera shells of equivalent size weigh on average 1/3 less than those from the middle latitudes. The carbonate preservation state of the samples was assessed by high resolution X-ray microcomputed tomographic analyses of Globigerinoides ruber and Globorotalia truncatulinoides specimens. The specimen preservation was deemed good and does not overall explain …

Emerging Technologies And Approaches For In Situ, Autonomous Observing In The Arctic, Craig M. Lee, Michael Degrandpre, John Guthrie, Victoria Hill, Ron Kwok, James Morison, Christopher J. Cox, Hanumant Singh, Timothy P. Stanton, Jeremy Wilkinson

OES Faculty Publications

Understanding and predicting Arctic change and its impacts on global climate requires broad, sustained observations of the atmosphere-ice-ocean system, yet technological and logistical challenges severely restrict the temporal and spatial scope of observing efforts. Satellite remote sensing provides unprecedented, pan-Arctic measurements of the surface, but complementary in situ observations are required to complete the picture. Over the past few decades, a diverse range of autonomous platforms have been developed to make broad, sustained observations of the ice-free ocean, often with near-real-time data delivery. Though these technologies are well suited to the difficult environmental conditions and remote logistics that complicate Arctic …

A Subsurface Eddy Associated With A Submarine Canyon Increases Availability And Delivery Of Simulated Antarctic Krill To Penguin Foraging Regions, K. Hudson, M. J. Oliver, J. Kohut, Michael S. Dinniman, John M. Klinck, M. A. Cimino, K. S. Bernard, H. Statscewich, W. Fraser

OES Faculty Publications

The distribution of marine zooplankton depends on both ocean currents and swimming behavior. Many zooplankton perform diel vertical migration (DVM) between the surface and subsurface, which can have different current regimes. If concentration mechanisms, such as fronts or eddies, are present in the subsurface, they may impact zooplankton near-surface distributions when they migrate to near-surface waters. A subsurface, retentive eddy within Palmer Deep Canyon (PDC), a submarine canyon along the West Antarctic Peninsula (WAP), retains diurnal vertically migrating zooplankton in previous model simulations. Here, we tested the hypothesis that the presence of the PDC and its associated subsurface eddy increases …
