Gendered Violence And Identities: Exploring The Role Of Violence Against And Abductions Of Women In Cracking India And Lajwanti, Erin Mammel

Electronic Theses and Dissertations 2020 - Present

This article argues that representations of women’s bodies as symbols of honor during the partition of India and Pakistan in Bapsi Sidhwa’s Cracking India and Rajinder Singh Bedi’s Lajwanti frame violence against these bodies, and forced conversions and marriages, as forms of dishonor among religious rivals within split territories, which attempt to uphold men’s nationalistic identities. Many scholars, such as Rachna Mehra and Rituparna Roy, have studied the displacement of recovered and rehabilitated women in these texts. There has been less scholarship, however, that explores gendered forms of violence with Hindu nationalist notions of masculinity. Through the lens of postcolonial …

Best Friends And Popular Peers As Sources Of Influence During Late Childhood And Early Adolescence, Mary Page James

Electronic Theses and Dissertations 2020 - Present

Across the transition into adolescence, changes in the child’s social world give rise to growing peer influence. As adult supervision declines and time with peers increases, children and adolescents become increasingly susceptible to influence from friends and popular peers. Unclear, however, is the relative magnitude of each and whether the scope of their influence varies across different domain behavior. Friends dominate private settings, where behaviors that promote reciprocity are particularly salient. Popular peers dominate public settings, where behaviors that promote hierarchy are particularly salient. The present study concerns the unique hypothesis that peer influence is domain specific, such that best …

The Interaction Of Temporal And Structural Abstractions And Their Influence On Behavior, Ryan Gallagher

Electronic Theses and Dissertations 2020 - Present

The prefrontal cortex (PFC) plays a crucial role in complex behaviors such as planning, decision-making, and adaptive problem-solving, which require integrating new information over time. Research has shown that information related to these behaviors is organized along a hierarchical rostro-caudal abstraction gradient in PFC, with abstract information represented in rostral (anterior) regions and concrete relationships in caudal (posterior) regions. Abstraction involves generalizing information by emphasizing broader concepts over specific details and can be understood more specifically by the context its applied to. However, past studies often confound different forms of abstraction, making it unclear how these different types of abstraction …

Movie Genre Classification Using Script Texts, Michael Roman Cuomo

Electronic Theses and Dissertations 2020 - Present

Genres are used to classify movies so that they can be grouped with others that have similar themes and structures. These classifications are categories created by humans. In the process of creating a movie, a script is often the first creation to write and share ideas about a topic. The script contains large amounts of text that is used to describe the dialog, setting and direction of the film. Although the script contains important information for the film, the amount of text can present a challenge for machine learning algorithms. Often in studies on film classification, if text is used, …

Interleukin-1 Type I Receptor Implicated In Emergence And Severity Of Generalized Tonic-Clonic Seizures In A Transgenic Mouse Model Of Adult-Onset, Progressive Epilepsy:, Tashi Dillon

Electronic Theses and Dissertations 2020 - Present

Interleukin-1 β (IL- 1β) is a proinflammatory cytokine with proconvulsive properties that is elevated in epilepsy. The hippocampal dentate gyrus (DG) buffers hyperexcitability, and deficits in granule neuron gating contribute to epileptogenesis. Excess brain derived neurotrophic factor (BDNF) may drive hyperexcitable circuit assembly, promoting a seizure-producing breakdown of the gating function. We use a transgenic mouse model of forebrain BDNF (TgBDNF) overexpression that exhibit spontaneous generalized tonic/ clonic seizures (GTCSs) at ~3 months, which progress as evidenced by prolonged periods of post-generalized EEG suppression (PGES). This is accompanied by hippocampal hypertrophy and brainstem cell loss. A strain globally lacking IL-1 …

Do Marketers Need To Know? How Firms' Newfound Quest For Customer Data Is Eroding Firm Performance, Victor Garcia

Electronic Theses and Dissertations 2020 - Present

Crowding Out Whistleblower Altruism: Examining The Impact Of Whistleblower Incentives And Recognition On Retaliatory Behaviors, Megan Nicole Hiner

Electronic Theses and Dissertations 2020 - Present

Whistleblowers play an instrumental role in exposing organizational wrongdoing and, thereby, helping to remedy the damage endured by stakeholders. However, whistleblower retaliation is rising, its personal impacts to the whistleblower are severe, and fears of retaliation serve as a strong deterrent to prospective whistleblowers. In this dissertation, I draw on motivation crowding theory, which posits that external interventions can crowd out or crowd in intrinsic motivations for engaging in a behavior. I employ a third-party perspective of motivation crowding theory and utilize a 2x3x2 between-participants experimental design to examine factors that impact employees’ perceptions of whistleblower intent and acts of …

Veterans In Times Of Crisis: The Impact Of Veteran Status On Unemployment, Lubor Olsovsky

Electronic Theses and Dissertations 2020 - Present

The purpose of this research is to investigate the impact of veteran status on unemployment in times of crisis. Driven by the social identity theory, we argue that people’s identity deriving from his or her military background makes them more valuable assets in the work environment, specifically in times of crisis, because of their human capital. We utilize the coronavirus pandemic as the exogenous shock in the labor marketplace, capturing the crisis environment. Due to the veterans’ human capital driven by their leadership and entrepreneurial characteristics from their military experience, we argue that individuals with veteran backgrounds have stronger labor …

Top Management Team Composition And Financial Reporting Quality: A Faultline Perspective, Tyler Ricco

Electronic Theses and Dissertations 2020 - Present

This study examines whether faultlines within top management teams (TMT) influence financial reporting quality (FRQ). Faultlines reflect hypothetical divisions within a group based on team members’ unique demographic characteristics and experiences. Using a large sample of U.S. firms from 2003 to 2020, I construct a faultline measure based on executive gender, age, tenure, education, and board experience. I test whether faultlines negatively associate with FRQ, proxied by measures of restatements and accruals quality. I further investigate faultline type, based on the demographic (gender and age) and task-related (tenure, education, and board experience) components. The main results do not support the …

Decreasing Food Waste In Home Kitchens By Increasing Food Literacy, Thao Rich

Student Publications

In a world that produces enough food for all of its occupants, a staggering amount of it bypasses empty stomachs and goes into landfills every day. There it sits in a plastic bag, which delays decomposition and increases the harmful greenhouse gas emissions. There are numerous reasons for the inequitable distribution of food ranging from politics to logistics, but the fact is that each person can make a dent in reducing their carbon footprint by simply reducing the amount of food they place in the trash each week. Food waste reduction is a small goal that requires no additional spending, …

"We'll Never Get This Opportunity Again": Lived Experiences Of Platform-Based Gig Workers, Catey Hoehn

Cal Poly Humboldt theses and projects

Platform-based gig work has rapidly expanded in the United States, leading to growing concerns about economic precarity, algorithmic management, and the sustainability of labor performed through apps. Gig work has been accused of fostering exploitative conditions, masking control through the language of flexibility, and deepening cycles of debt and insecurity for workers. However, the lived experiences of gig workers often reveal complexities that differ from public narratives and company portrayals. This thesis builds on sociological studies of labor precarity to examine how platform-based gig workers experience, internalize, and resist algorithmic control. Utilizing qualitative semi-structured interviews, fifteen rideshare and delivery drivers …

Twice-Exceptionalism And The Complexity Of Supporting Students Who Are Both Gifted And Disabled, River Johnathon Taylor

Cal Poly Humboldt theses and projects

Drawing on ideas from disabilities studies about compulsory able-bodiedness as well as experiences of disability being fluid and context dependent, this study posits that giftedness, just like disability, is a complex multidimensional form of identity that is both context and temporally dependent. Twice-exceptionalism is defined as an identity in which an individual is gifted in at least one domain of human productivity and manifests at least one disability. Students with unique learning needs (students with disabilities, students with giftedness, and students with twice-exceptionalism) face many complex challenges within Humboldt County, California.
