Edging towards understanding: Illuminating student experiences of liminality in introductory sociology
No full textThe chapter, "Edging towards understanding: Illuminating student experiences of liminality in introductory sociology" was written by Alison M. Thomas (Douglas College Faculty). This book had its beginnings on the edge of the North Atlantic Ocean, when international scholars from all over the globe met in Halifax, Nova Scotia at the 6th International Biennial Threshold Concepts Conference held over the three days of 15-17 June 2016."-- Preface.
International Biennial Threshold Concepts Conference (6th : 2016 : Dalhousie University)
Since the first literature about the Threshold Concepts Framework was published in 2003, a considerable body of educational research into this topic has grown internationally across a wide range of disciplines and professional fields. Successful negotiation of a threshold concept can be seen as crossing boundaries into new conceptual space, or as a portal opening up new and previously inaccessible ways of thinking about something. In this unfamiliar conceptual terrain, fresh insights and perceptions come into view, and access is gained to new discourses. This frequently entails encounters with 'troublesome knowledge', knowledge which provokes a liminal phase of transition in which new understandings must be integrated and, importantly, prior conceptions relinquished. There is often double trouble, in that letting go of a prevailing familiar view frequently involves a discomfiting change in the subjectivity of the learner. We become what we know. It is a space in which the learner might become 'stuck'. Threshold Concepts on the Edge, the fifth volume in a series on this subject, discusses the new directions of this research. Its six sections address issues that arise in relation to theoretical development, liminal space, ontological transformations, curriculum, interdisciplinarity and aspects of writing across learning thresholds" -- Provided by publisher.book chapterPublished
Reduced dimension modeling of leading edge turbulent interaction noise
No full textA computational aeroacoustics approach is used to model the effects of real airfoil geometry on leading edge turbulent interaction noise for symmetric airfoils at zero angle of attack. For the first time, one-component (transverse), two-component (transverse and streamwise), and three-component (transverse, streamwise, and spanwise) synthesized turbulent disturbances are modeled instead of single frequency transverse gusts, which previous computational studies of leading edge noise have been confined to. The effects of the inclusion of streamwise and spanwise disturbances on the noise are assessed, and it is shown that accurate noise predictions for symmetric airfoils can be made by modeling only the transverse disturbances, which reduces the computational expense of simulations. Additionally, the two-component turbulent synthesis method is used to model the effects of airfoil thickness on the noise for thicknesses ranging from 2% to 12%. By using sufficient airfoil thicknesses to show trends, it is found that airfoil thickness will reduce the noise at high frequency, and that the sound power P will reduce linearly with increasing airfoil thickness
Domain wall motion in perpendicular anisotropy nanowires with edge roughness
No full textWe study field-driven domain wall (DW) motion in nanowires with perpendicular magnetic anisotropy using finite element micromagnetic simulations. Edge roughness is introduced by deforming the finite element mesh, and we vary the correlation length and magnitude of the roughness deformation separately. We observe the Walker breakdown both with and without roughness, with steady DW motion for applied fields below the critical Walker field Hc, and oscillatory motion for larger fields. The value of Hc is not altered in the presence of roughness.The edge roughness introduces a depinning field. During the transient process of depinning, from the initial configuration to steady DW motion, the DW velocity is significantly reduced in comparison to that for a wire without roughness. The asymptotic DW velocity, on the other hand, is virtually unaffected by the roughness, even though the magnetization reacts to the edge distortions during the entire course of motion, both above and below the Walker breakdown.A moving DW can become pinned again at some later point ('dynamic pinning'). Dynamic pinning is a stochastic process and is observed both for small fields below Hc and for fields of any strength above Hc. In the latter case, where the DW shows oscillatory motion and the magnetization in the DW rotates in the film plane, pinning can only occur at positions where the DW reverses direction and the instantaneous velocity is zero, i.e., at the beginning or in the middle of a positional oscillation cycle. In our simulations pinning was only observed at the beginnings of cycles, where the magnetization is pointing along the wire.The depinning field depends linearly on the magnitude of the edge roughness. The strongest pinning fields are observed for roughness correlation lengths that match the domain wall width
