Magnetic Monopoles, Center Vortices, Confinement and Topology of Gauge Fields
The vortex picture of confinement is studied. The deconfinement phase
transition is explained as a transition from a phase in which vortices
percolate to a phase of small vortices. Lattice results are presented in
support of this scenario. Furthermore the topological properties of magnetic
monopoles and center vortices arising, respectively, in Abelian and center
gauges are studied in continuum Yang-Mills-theory. For this purpose the
continuum analog of the maximum center gauge is constructed.Comment: talk given by H. Reinhardt on the Int. Workshop ``Hadrons 1999'',

A general solution in the Newtonian limit of f(R)- gravity
We show that any analytic -gravity model, in the metric approach,
presents a weak field limit where the standard Newtonian potential is corrected
by a Yukawa-like term. This general result has never been pointed out but often
derived for some particular theories. This means that only allows to
recover the standard Newton potential while this is not the case for other
relativistic theories of gravity. Some considerations on the physical
consequences of such a general solution are addressed.Comment: 5 page
Energies of Quantum QED Flux Tubes
In this talk I present recent studies on vacuum polarization energies and
energy densities induced by QED flux tubes. I focus on comparing three and four
dimensional scenarios and the discussion of various approximation schemes in
view of the exact treatment.Comment: 9 pages latex, Talk presented at the QFEXT 05 workshop in Barcelona,

Informing or Exploiting? Public Reponses to Giuliana Rancic’s Health Narrative
Popular entertainment journalist Giuliana Rancic has shared her struggles with pregnancy loss, infertility, and breast cancer in an array of public forums. In this study, we analyzed online comments responding to public discourses surrounding Rancic’s revelations, including her miscarriage and fertility treatments, her breast cancer diagnosis, and her decision to undergo a double mastectomy. Our goal was to explore how the public framed Rancic’s health challenges. Using a narrative lens, we argue that online comments reveal the tensions that celebrities like Rancic must manage as they contend with public scrutiny of their stories. Online commenters in this study framed Rancic’s narrative as a privileged vantage point in which she exploited her health struggles for personal and financial gain. Our analysis of these comments also demonstrates how Rancic’s narrative exists in concert with other discourses that challenge and disrupt her own account of events. The examination of these mediated discourses has implications for understanding the role of celebrity experiences in personal and public conversations about health
