Age-Group Differences In Friend Influence Over Academic Achievement And Physical Activity, Laury-Ann Bedard Leclerc

Electronic Theses and Dissertations 2020 - Present

Speculation about the developmental shifts in the magnitude of peer influence has outstripped empirical research. Friends are assumed to be particularly influential at the onset of adolescence, as adult oversight declines and the salience of peers increases. Few studies, however, have explored age-group differences in the magnitude of friend influence over academic achievement and physical activity. The present longitudinal study compares friendship dyads in late childhood (grades 4-5) versus early adolescence (grades 6-7), describing the strength of their mutual influence across peer- and self-reports of academic achievement and physical activity. Participants included 170 adolescents (99 girls, 71 boys) in 85 …

Investigating The Portrayal Of Native Americans In Florida’S K-12 Social Studies/History Textbooks: A Critical Content Analysis, Marisa Miceli Schnirman

Electronic Theses and Dissertations 2020 - Present

Textbook bias is an enduring and contentious issue in the United States. U.S. textbooks have long been criticized for perpetuating bias and reinforcing dominant narratives that marginalize minority groups, such as members of Indigenous nations. This study confirms that biases continue to exist in textbooks and promote the harmful narrative that Indigenous peoples are people of the past. This narrative undermines the survivance (Vizenor, 1998), contributions, and very existence of Indigenous peoples. Using a critical lens, this content analysis examines the portrayal of Indigenous peoples in select fourth-grade, eighth-grade, and high school social studies and history texts used in Florida …

The Effect Of Political Ideology On The Persuasiveness Of Gainvs. Loss-Framed Climate Change Messages: Testing Competing Hypotheses, Sada Rice

Electronic Theses and Dissertations 2020 - Present

Motivating climate change mitigation is a critical priority. This study examined how message framing (gain vs. loss) interacts with political ideology to influence persuasion. Two competing hypotheses were tested. The Regulatory Focus Fit Hypothesis predicted that liberals (promotion-oriented) would prefer gain-framed messages, while conservatives (prevention-oriented) would prefer loss-framed ones. The Differential Context Hypothesis predicted the opposite: liberals would respond better to loss frames due to alignment with threat-based media narratives, while conservatives would prefer gain frames due to lower reactance and perceived novelty. Messages were also tailored to match individual regulatory focus or the broader political context. Results did not …

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, …
