Neural signals encoding shifts in beliefs
Dopamine is implicated in a diverse range of cognitive functions including cognitive flexibility, task switching, signalling novel or unexpected stimuli as well as advance information. There is also longstanding line of thought that links dopamine with belief formation and, crucially, aberrant belief formation in psychosis. Integrating these strands of evidence would suggest that dopamine plays a central role in belief updating and more specifically in encoding of meaningful information content in observations. The precise nature of this relationship has remained unclear. To directly address this question we developed a paradigm that allowed us to decompose two distinct types of information content, information-theoretic surprise that reflects the unexpectedness of an observation, and epistemic value that induces shifts in beliefs or, more formally, Bayesian surprise. Using functional magnetic-resonance imaging in humans we show that dopamine-rich midbrain regions encode shifts in beliefs whereas surprise is encoded in prefrontal regions, including the pre-supplementary motor area and dorsal cingulate cortex. By linking putative dopaminergic activity to belief updating these data provide a link to false belief formation that characterises hyperdopaminergic states associated with idiopathic and drug induced psychosis
Sentence Building in Reading and Composition
The primary objective of this article is to describe an instructional technique called sentence building as a means of developing the ability to read more complex sentences with understanding and to write more complex sentences. The process may be viewed as a preliminary step to reading and writing paragraphs. A secondary objective is to develop an awareness that instruction in reading and composition should be based on oral language skills and may be taught concomitantly
Native not Queer: Performance and Identity Conflict for Sherman Alexie\u27s Native Americans
Images of Indians in popular culture often perpetuate stereotypes and overlook the diversity of Native American tribes and identities. In the works of contemporary Native American author/filmmaker Sherman Alexie, I argue, we see how “Indianness” requires a performative element deriving from stereotypes that seem authentic and legitimate to others by conforming to dominant myths of Indian identity. The conflicts surrounding representation of Native Americans include the difficulty of exploring queer Native American identities. My paper utilizes Lisa Tatonetti\u27s framework in her essay Visible Sexualities or Invisible Nations, in which Indian identities are unable to accommodate queerness due to pervasive legacies of settler colonialism in their depictions of LGBTQ Native people. These representations subsequently lack the intersectionality available for other racial identities. For example, Alexie\u27s The Business of Fancydancing presents the tension between the reservation and the gay urban space in which the main character is unable to synthesize both identities. Alexie\u27s characters frequently utilize and juxtapose cultural stereotypes to examine how they differ from expected components of Native American identity. Examining this film and other works by Alexie, I argue that the performative demand to appear Indian enough in these texts disrupts the synthesis of queer and Native American identities
Increasing Communication Between Administrators and Reading Personnel
What do administrators believe are the strong and weak points in their district\u27s reading program? How do they evaluate the performance and capabilities of reading personnel? Do principals at the elementary and secondary levels differ in their expectations of the reading program

Martha Thomas Fitzgerald Papers - Accession 273
The Martha Thomas Fitzgerald Papers consist of biographical data, correspondence, minutes, newspaper clippings, memoranda, reports, and photographs (of particular interest are the many photographs of rural S.C. school houses in the 1920s). The collection pertains to Mrs. Fitzgerald’s work with the South Carolina Department of Education, the South Carolina House of Representatives, and her work with various civic organizations such as the Altrusa Club, the League of Women Voters, the Daughters of American Colonists, United Daughters of the Confederacy (UDC), Business and Professional Women’s Club (BPW), Delta Kappa Gamma, South Carolina Vocational Rehabilitation, and the Salvation Army. There is also information on the Status of Women Commission Council on Aging, agriculture, Queens College, University of South Carolina, Winthrop University, Columbia University, public health, South Carolina history, City of Columbia, South Carolina, and Richland County, South Carolina. Correspondents include Strom Thurmond and three letters from John F. Kennedy when he was senator. Mrs. Fitzgerald was the first woman elected to the South Carolina House of Representatives in a general election.https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/1160/thumbnail.jp
