Cultural Competence: New Conceptual Insights into its Limits and Potential for Addressing Health Disparities

The increasing interest in the role of racism and racialization in health disparities, calls for exploring new paradigms in addressing and eliminating health disparities related to race/ethnicity. Cultural competence is conceptualized as one of the keys ways to address racial/ethnic disparities in public health and healthcare. However, for cultural competence to fulfill this role, it requires a critical understanding of the underlying socio-political and economic processes of power, privilege and institutional racism that create, support and maintain existing health disparities. This paper outlines how the concept of cultural competence can be made more robust, by incorporating concepts such as Public Health Critical Race praxis (PHCR) and cultural humility, to more fully tackle the impact of structural inequities on health disparities

Twisted Alexander Invariants of Twisted Links

Let L be an oriented (d+1)-component link in the 3-sphere, and let L(q) be the d-component link in a homology 3-sphere that results from performing 1/q-surgery on the last component. Results about the Alexander polynomial and twisted Alexander polynomials of L(q) corresponding to finite-image representations are obtained. The behavior of the invariants as q increases without bound is described.Comment: 21 pages, 6 figure

Twisted Alexander Polynomials and Representation Shifts

For any knot, the following are equivalent. (1) The infinite cyclic cover has uncountably many finite covers; (2) there exists a finite-image representation of the knot group for which the twisted Alexander polynomial vanishes; (3) the knot group admits a finite-image representation such that the image of the fundamental group of an incompressible Seifert surface is a proper subgroup of the image of the commutator subgroup of the knot group.Comment: 7 pages, no figure
