On the Nature of Neural Causality in Large-Scale Brain Networks: Foundations, Modeling and Nonlinear Neurodynamics
Title
On the Nature of Neural Causality in Large-Scale Brain Networks: Foundations, Modeling and Nonlinear Neurodynamics.
Creator
Mannino, Michael, Bressler, Steven L., Florida Atlantic University, Charles E. Schmidt College of Science, Center for Complex Systems and Brain Sciences
Abstract/Description
We examine the nature of causality as it exists within large-scale brain networks by first providing a rigorous conceptual analysis of probabilistic causality as distinct from deterministic causality. We then use information-theoretic methods, including the linear autoregressive modeling technique of Wiener-Granger causality (WGC), and Shannonian transfer entropy (TE), to explore and recover causal relations between two neural masses. Time series data were generated by Stefanescu-Jirsa 3D...
Show moreWe examine the nature of causality as it exists within large-scale brain networks by first providing a rigorous conceptual analysis of probabilistic causality as distinct from deterministic causality. We then use information-theoretic methods, including the linear autoregressive modeling technique of Wiener-Granger causality (WGC), and Shannonian transfer entropy (TE), to explore and recover causal relations between two neural masses. Time series data were generated by Stefanescu-Jirsa 3D model of two coupled network nodes in The Virtual Brain (TVB), a novel neuroinformatics platform used to model resting state large-scale networks with neural mass models. We then extended this analysis to three nodes to investigate the equivalence of a concept in probabilistic causality known as ‘screening off’ with a method of statistical ablation known as conditional Granger causality. Finally, we review some of the empirical and theoretical work of nonlinear neurodynamics of Walter Freeman, as well as metastable coordination dynamics and investigate what impact they have had on consciousness research.

An examination of relationships between mindfulness, personality, anxiety, and depression in Americans and Japanese college students.
Creator

Abstract/Description
Mindfulness – nonjudgmental awareness of the present moment - has recently garnered significant attention in psychological literature for decreasing clinical symptoms. Certain personality traits such as emotionality, however, can predict higher levels of anxiety and depression. The present study examines whether mindfulness mediates the relationship between personality traits and perceived stress and depression in nonclinical populations.

Show moreMindfulness – nonjudgmental awareness of the present moment - has recently garnered significant attention in psychological literature for decreasing clinical symptoms. Certain personality traits such as emotionality, however, can predict higher levels of anxiety and depression. The present study examines whether mindfulness mediates the relationship between personality traits and perceived stress and depression in nonclinical populations. A total of 321 participants from two samples—American and Japanese undergraduates —self-reported scores on measures of mindfulness, personality, perceived stress and depression. Cross-cultural comparisons following measurement invariance tests also allow for insight into the definition of mindfulness, especially given the Eastern religion origin of mindfulness. Results demonstrate that mindfulness partially mediates the relationships between personality clinical symptoms, particularly for extraversion and conscientiousness. These results can play an important role for developing mindfulness-based treatment and prevention programs and bridge an important gap between Western conceived and Eastern religion mindfulness.

Perceptions of the environment: an ethnographic study of sensory awareness and environmental activism among south Florida yoga practitioners.
Creator
Weisner, Meagan L., Cameron, Mary, Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, Department of Anthropology
Abstract/Description
The practice of yoga is an increasingly popularized movement within the West that incorporates the desire for physical fitness, spiritual consciousness, and environmentalism. Emanating from the New Age movement, the popularity of yoga has proliferated as a subculture that seeks to encourage mind–body wellbeing while representing an ethos that assumes environmental responsibility. This thesis examines the techniques of modern yoga and the influence that asana (posture) and meditational...
Show moreThe practice of yoga is an increasingly popularized movement within the West that incorporates the desire for physical fitness, spiritual consciousness, and environmentalism. Emanating from the New Age movement, the popularity of yoga has proliferated as a subculture that seeks to encourage mind–body wellbeing while representing an ethos that assumes environmental responsibility. This thesis examines the techniques of modern yoga and the influence that asana (posture) and meditational relaxation have on the senses and subsequently on environmental awareness and activism.

"mental crisis" of John Stuart Mill: The destruction of a mechanical consciousness
Title
The "mental crisis" of John Stuart Mill: The destruction of a mechanical consciousness.
Creator
Dhuwalia, Raj Kumar., Florida Atlantic University, Buckton, Oliver
Abstract/Description
In Chapter Five of his Autobiography, John Stuart Mill discusses a "mental crisis" which struck in 1826 and lingered for some time. Mill addresses one causative element of this crisis, a perception of himself at twenty as a "mechanical man." Yet these much-quoted words understate a greater point. I shall argue that Mill's crisis was the destruction of an almost purely mechanical consciousness, or at least a strike at his foundations of a breadth and severity that has not been fully addressed...
Show moreIn Chapter Five of his Autobiography, John Stuart Mill discusses a "mental crisis" which struck in 1826 and lingered for some time. Mill addresses one causative element of this crisis, a perception of himself at twenty as a "mechanical man." Yet these much-quoted words understate a greater point. I shall argue that Mill's crisis was the destruction of an almost purely mechanical consciousness, or at least a strike at his foundations of a breadth and severity that has not been fully addressed by Mill scholarship. I shall consider various aspects of Mill's life and thought before and after the crisis as a means of identifying the nature of this fundamental change in Mill. These aspects of Mill's thought include philosophy, economics, epistemology, poetry, and politics, and these aspects of Mill's life include education, his relationship with his father and Bentham, his early activism, his influences, and his perceptions of man and society.

Women's feminist collective identity: A liberal feminist analysis of feminist identification and feminist consciousness

Women's feminist collective identity: A liberal feminist analysis of feminist identification and feminist consciousness.
Creator
Hiller, Tiffany Ann., Florida Atlantic University, Appleton, Lynn M.
Abstract/Description
Data from the 1992 American National Election Study are used to examine three issues: first, who is most likely to identify as a feminist; second, who is likely to show a feminist consciousness; and finally who possesses both the feminist identification and feminist consciousness that demonstrate a feminist collective identity. The results indicate that feminist identification and feminist consciousness are separate but related constructs and that overall feminist collective identity among...
Show moreData from the 1992 American National Election Study are used to examine three issues: first, who is most likely to identify as a feminist; second, who is likely to show a feminist consciousness; and finally who possesses both the feminist identification and feminist consciousness that demonstrate a feminist collective identity. The results indicate that feminist identification and feminist consciousness are separate but related constructs and that overall feminist collective identity among women is weak. The findings indicate a need to make clear which dimension--feminist identification or feminist consciousness--is being used in efforts to understand women's feminist collective identity and how these three concepts interact with cohort, employment status, income, education, race, and marital status.

Fallen from disgrace: tales of disillusion in Amiri Baraka’s Dutchman and v.s. Naipaul’s Guerrillas.
Creator
Osborne, Tamar C., Dagbovie-Mullins, Sika A., Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, Department of English
Abstract/Description
Despite radical differences in their political commentary, Amiri Baraka and V.S. Naipaul’s literary careers have obsessively centered on the divided Self of the colonized artist. Esther Jackson argues that Baraka’s “search for form” becomes “symbolic of a continuing effort to mediate between warring factions within the perceiving mind” (38). Similarly, many critics have interpreted Naipaul’s grave manifestos as the outpourings of a writer disenchanted with his own past and national identity....
Show moreDespite radical differences in their political commentary, Amiri Baraka and V.S. Naipaul’s literary careers have obsessively centered on the divided Self of the colonized artist. Esther Jackson argues that Baraka’s “search for form” becomes “symbolic of a continuing effort to mediate between warring factions within the perceiving mind” (38). Similarly, many critics have interpreted Naipaul’s grave manifestos as the outpourings of a writer disenchanted with his own past and national identity. For Selwyn Cudjoe, Naipaul’s work is “reflective of a man who failed to discover any psychological balance in his life” (172-173). This thesis analyzes how Amiri Baraka’s Dutchman and V.S. Naipaul’s Guerrillas engage with various fairy tale conventions in order to narrate the colonized victim’s divided Self. These narratives ultimately function as anti-fairy tales, revealing the black protagonist’s accursed position in the symbolic order.

Voice of society"
Title
"The Voice of society": Dickens' surprising lesson in diplomacy spoken by the "innocent" table in Our Mutual Friend.
Creator
Hernandez, Patricia., Harriet L. Wilkes Honors College
Abstract/Description
In Our Mutual Friend Dickens plays with the idea of people becoming things and things becoming people. One such person, who is initially introduced as a table, is Melvin Twemlow. This member of the aristocracy plays an almost comical, minor role within one sub-plot of the novel, but over the course of the novel progresses from a "feeble" character into a strong, morally authoritative voice. Dickens concludes his novel with a debate concerning who is, or should be, "the voice of society" and...
Show moreIn Our Mutual Friend Dickens plays with the idea of people becoming things and things becoming people. One such person, who is initially introduced as a table, is Melvin Twemlow. This member of the aristocracy plays an almost comical, minor role within one sub-plot of the novel, but over the course of the novel progresses from a "feeble" character into a strong, morally authoritative voice. Dickens concludes his novel with a debate concerning who is, or should be, "the voice of society" and the last word of the debate is given to the mysterious table-man character. Rather than allowing a central protagonist to champion his thoughts, Dickens surprises his readers by making an exemplary moral figure of a mild, minor character from among the ranks of the pompous aristocracy. Twemlow's speech makes a familiar Dickensian point about the need for social reform in a strange, politically incorrect way.
