Exclusion From The Good Life: The Impact Of Anti-Asian Racism On Asian Nebraskans, Heather Fryer, Sharon Ishii-Jordan

Truth and Reconciliation History Project

To understand how Americans of Asian descent experienced, adjusted, and overcame negative experiences in Nebraska, recognizing the external forces on their lives is paramount. The experiences of Asians in their diaspora across the U.S. and Nebraska during a 150-year span have been shaped by both external (global and domestic) and internal (personality and resilience) factors. The presence of stereotypes specifically targeted toward Asian Americans due to exotic imaginings, pseudoscience, and economic fears, in addition to the images created by national media, gave rise to society’s acceptance of stereotypes. These external factors contributed to a belief that continues to this day …

Young Adults’ Self-Perceptions Of Parenting Styles And Attachments Influencing Juvenile Criminality, Keristin Zanda Scott

Walden Dissertations and Doctoral Studies

Parenting styles, parent-to-child attachments, and parental involvements are contributing factors leading to juvenile delinquency. Adolescents are committing offending acts at a younger age, recidivating, and perpetrating with peers or parents. However, there is a lack of empirical research on juvenile perceptions of parenting, juvenile criminality, and desistance implications. The purpose of this interpretive phenomenological study was to explore past juvenile criminal offenders’ lived experiences and the corresponding influence parenting styles had on their deviant behaviors. Ainsworth and Bowlby’s attachment theory, Baumrind’s parenting style theory, and Bandura’s social learning theory provided a lens for examining young adults’ perceptions of parenting related …

Impacts Of The Conductive Networks On Solid-State Battery Operation, Shimao Deng, Yixian Wang, Tianxiao Sun, Wenlong Li, Mingyuan Ge, Jian Wang, Peter Cloetens, Piero Pianetta, David Mitlin, Yijin Liu

Faculty, Staff and Student Publications

The micromorphology of composite cathodes is known to play a vital role in determining all‐solid‐state battery (ASSB) performance. However, much of our current understanding is derived from empirical observations, lacking a deeper mechanistic foundation. The “rocking chair” concept of battery chemistry requires maintaining charge neutrality, emphasizing the necessity of examining electrode micromorphology from the perspective of conductive networks. This study systematically investigates the microscopic electrochemical impacts of conductive network micromorphology by varying the Li+‐to‐e− channel ratio in cathodes comprising LiNbO3‐coated LiNi0.8Co0.1Mn0.1O2, Li6PS5Cl, and carbon fibers. Utilizing multiscale synchrotron‐based spectro‐microscopy, we unravel that unbalanced Li+ and e− conducting channels intensify charge …

The Sudanese Identity In The Mirror Of Colonial And Post-Independence History, Abdalla Galaleldeen

The Journal of Social Encounters

After independence, Sudan’s political elite adopted colonial-inspired policies that sought to divide the country into North and South (Arabs versus Africans). This policy was further reinforced by the civil wars and by the failures of the Sudanese political elite to construct a cohesive national identity. In the post-independence period, one elite group aligned itself with an Arab identity, while another embraced an African identity. Logically, therefore, both identities—Islamic-Arab and African—encompass the majority of the population. Yet, while Islamists and Africanists each claimed to represent this majority, neither addressed the contradictions inherent in their positions. As the tension between the Islamic-Arab …
