Characteristics of temporal fluctuations in the hyperpolarized state of the cortical slow oscillation

We present evidence for the hypothesis that transitions between the low- and high-firing states of the cortical slow oscillation correspond to neuronal phase transitions. By analyzing intracellular recordings of the membrane potential during the cortical slow oscillation in rats, we quantify the temporal fluctuations in power and the frequency centroid of the power spectrum in the period of time before “down” to “up” transitions. By taking appropriate averages over such events, we present these statistics as a function of time before transition. The results demonstrate an increase in fluctuation power and time scale broadly consistent with the slowing of systems close to phase transitions. The analysis is complicated and limited by the difficulty in identifying when transitions begin, and removing dc trends in membrane potential

Cultural Identity Silencing of Native Americans in Education

This descriptive phenomenological study investigated: How is cultural identity silencing psychologically experienced by young adult Native Americans in education? Cultural identity silencing is the denial of the existence of cultural identity. Phenomenological interviewing and Giorgian analysis resulted in a descriptive structure of how cultural identity silencing is psychologically experienced by Native Americans in educational settings. These results contribute to a greater understanding of how Native Americans experience colonialist educational systems and thus has implications for survivance, identity development, and the decolonialization of education

An Evidence Based Methodology for Cultural Institutions Seeking to Identify and Profile their Local Populations

This is the author accepted manuscript. The final version is available from Taylor & Francis (Routledge) via the DOI in this record.Community is a term utilised in policy to describe a collective target audience for public services. Political requirements mean that delivering direct and indirect benefits to local people is regarded as essential to obtaining public sources of funding for cultural organisations. Regardless of any external pressure, cultural organisations strive to be conscious, receptive or inclusive of the views of the public. This paper summarises how a robust approach was developed to identify and profile groupings of residents within an area in relation to their local civic museum (UK). This method resulted in a nuanced understanding of a museum’s local population, identifying groupings upon which to base its future plans. Crucially, the methods outlined in this paper are transferable to cultural institutions in different settings worldwide. Our discussion contributes to the wider endeavour of evidencing impacts of museums on variously defined communities
