Story-telling: A telling approach in healthcare education

Paper presented at the 2nd The Narrative Practitioner international conference at NEWI in Wrexham, UK, 23-25 June 2008.This powerpoint presentation and associated notes discusses storytelling as a teaching strategy within healthcare. It gives the background to investigating the use of storytelling and discusses the findings from the literature. It is further supported by a small piece of research undertaken, which identifies ‘good reads’ recommended by healthcare lecturers

Digitized synchronous demodulator

A digitized synchronous demodulator is constructed entirely of digital components including timing logic, an accumulator, and means to digitally filter the digital output signal. Indirectly, it accepts, at its input, periodic analog signals which are converted to digital signals by traditional analog-to-digital conversion techniques. Broadly, the input digital signals are summed to one of two registers within an accumulator, based on the phase of the input signal and medicated by timing logic. At the end of a predetermined number of cycles of the inputted periodic signals, the contents of the register that accumulated samples from the negative half cycle is subtracted from the accumulated samples from the positive half cycle. The resulting difference is an accurate measurement of the narrow band amplitude of the periodic input signal during the measurement period. This measurement will not include error sources encountered in prior art synchronous demodulators using analog techniques such as offsets, charge injection errors, temperature drift, switching transients, settling time, analog to digital converter missing code, and linearity errors

Classifying Finite Dimensional Cubulations of Tubular Groups

A tubular group is a group that acts on a tree with $\mathbb{Z}^2$ vertex stabilizers and $\mathbb{Z}$ edge stabilizers. This paper develops further a criterion of Wise and determines when a tubular group acts freely on a finite dimensional CAT(0) cube complex. As a consequence we offer a unified explanation of the failure of separability by revisiting the non-separable 3-manifold group of Burns, Karrass and Solitar and relating it to the work of Rubinstein and Wang. We also prove that if an immersed wall yields an infinite dimensional cubulation then the corresponding subgroup is quadratically distorted.Comment: 24 pages, 11 figures. Minor corrections and clarifications. Some figures are redrawn. The proof of Theorem 6.1 is rewritten for clarity and to correct error

Are You My Mother?: Conceptualizing Children’s Identity Rights in Transracial Adoptions

I. Adoption and the Clash of Rights Perspectives Adoption law in the United States, depending on whom you ask, is either at a turning point or hopelessly gridlocked. 1 Many issues seem to defy consensus. Media reports of high profile adoption cases 2 have attracted enormous attention, not only because of their inherent drama, but also because they implicate highly contested definitions of what makes a family. Many of the most volatile adoption issues are couched in terms of rights: the birth mother\u27s right to confidentiality; the adoptive parent\u27s right to be treated equally without regard to race, ethnicity, religion, or sexual orientation; the rights of a racial, ethnic, or national community to custody and control of children born into that community; the adult adoptee\u27s right to information about her origins; the right of unwed fathers to veto the birth mother\u27s adoption decision, and so on, ad infinitum. These clashes of rights highlight the tensions between claims of blood and nurture, biological and social connection, and individual and communal definitions of self. Of all the debates, the furor over racial matching in adoption is perhaps the most problematic for American legal culture. Most recently in the United States, Congress enacted the Multiethnic Placement Act (MPA). 3 Originally designed to avoid delay stemming from reluctance to place children in homes with parents of another race or ethnicity, the MPA has become a battleground for competing visions of individual and group identity and has revived longstanding controversies about ..

Between

Between is a performance inhabited by three dancers and up to 30 viewers that explores the tension between visual spectacle and intimacy. A collaboration with Angela Woodhouse, the piece offers the choice of experience as spectator or participant; moments when the attention is directed or divided; and it explores the tensions between distance and actual contact. It has been touring since 2010 to six venue

Quasi-isometric groups with no common model geometry

A simple surface amalgam is the union of a finite collection of surfaces with precisely one boundary component each and which have their boundary curves identified. We prove if two fundamental groups of simple surface amalgams act properly and cocompactly by isometries on the same proper geodesic metric space, then the groups are commensurable. Consequently, there are infinitely many fundamental groups of simple surface amalgams that are quasi-isometric, but which do not act properly and cocompactly on the same proper geodesic metric space.Comment: v2: 19 pages, 6 figures; minor changes.
