Demons and Abelian Projection QCD: Action and Crossover
I evaluate S_{APQCD}, the exact action of Abelian projection QCD, using the
microcanonical demon method. Starting with a trial action consisting of L=1,
L=2, & L=3 LxL plaquettes plus a Smit-van-der-Sijs magnetic monopole ``mass''
operator, I show that coefficients of the L=2 and L=3 plaquettes vanish at all
beta_{SU2}. In fact, at strong coupling S_{APQCD} is essentially the 1x1
compact QED action with beta_{U1}=beta_{SU2}/2. Beyond beta_{SU2}>=2, S_{APQCD}
gains an exogenous negative 1x1x1 magnetic monopole mass shift. Note that my
approach differs fundamentally from the Smit-van-der-Sijs approach in that I do
not make an a priori assumption about monopole or plaquette size in S_{APQCD}.
Indeed, these results suggest that QCD monopoles are pointlike, in contrast to
the ``effective'' condensation picture put forth by Smit and van der Sijs.Comment: to appear in Physics Letters B347 (1995) 367-37
Dynamic literature mapping : typography in screen-based media
This paper chronicles the development of a visual map representing a literature search on key theorists and thinkers in two principal topics: Typography and New Media. Its aim is to visualise and facilitate conceptual connections between key ideas and philosophies across disciplines. This literature map was drawn up by reviewing available influential literature within these topics. Related categories were later added and a further series of literature searches were conducted to build references in each topic. This on-going cyclical process serves to construct a comprehensive contextual map of knowledge. The benefit of the map is twofold. Primarily, aiding the researcher to navigate and understand complex layers of information. Secondly, allowing the researcher to present and share representations of knowledge. The clarity of the representation is crucial in eliciting the participation of fellow design researchers and practitioners to the development and growth of the literature map
Capturing tacit knowledge: Documenting and understanding recent methodological innovation used in Design Doctorates in order to inform Postgraduate training provision
This paper presents a preliminary review of recent Design PhDs that identify and analyse the methodological innovation that is occurring in the field, in order to inform future provision of research training for Design PhDs. Six recently completed Design PhDs are used to highlight possible philosophical and practical models that can be adopted by future PhD design students. Four characteristics were found in Design PhD methodology; thesis-structural innovation, a ‘pick and mix’ research design approach, situating practice in the enquiry and the validation of visual analysis. The paper concludes by offering suggestions on how research training can be improved for Design PhD candidates. By being aware of recent methodological innovations in the field, design educators will be better informed when developing resources for future design doctoral candidates, and assisting supervision teams in developing a more informed and flexible approach to practice-led research
