The rhetoric of auscultation: Corporeal sounds,mediated bodies,and abortion rights

This essay argues that corporeal sound, including the spoken voice and the auscultated heartbeat, can be understood as material rhetoric, and that material rhetoric, by extension, should be understood as both a force and a networked fluid. I illustrate this argument through the case study of abortion practices and policies, arguing that both mandated heartbeat auscultation and physician speech-and-display provisions represent the forceful fluidity of material rhetoric and demonstrate the power of such rhetoric to carve out networks of meaning. Through this networking, sound’s material role in defining autonomy takes on a powerful role in debates over fetal personhood.     

Development of a competency model and tailored assessment method for high school science teachers utilizing a flipped learning approach

Many professional development programs aim to improve student outcomes by enhancing teacher competencies. Effective evaluation of these programs requires a clear delineation of the competencies to be gained. A competency model was developed to evaluate the impact of a teacher professional program that aimed to improve teachers’ ability to effectively implement technologically engaged modules in a flipped classroom setting. Competencies were identified via participatory evaluation techniques and assessments were aligned to the competencies. The competency of teachers in the knowledge, skills, and abilities needed for creation and delivery of effective flipped lessons can be tracked using a radar graph to guide tailored professional development.

     

Experimental study on bonding properties between steel strand and concrete at cryogenic temperatures

To study the bonding properties between steel strand and concrete at room and cryogenic temperatures, a series of center pullout experiments were conducted on 96 bonding anchorage specimens at the lowest temperature of-165 ℃. The impacts on the bonding property of such parameters as the temperature, concrete strength, the relative concrete cover thickness, and the relative anchorage length were analyzed. The test results indicate that the changes in temperature have a clear effect on the bonding property between steel strand and concrete. As the temperature decreases, the bond stress, which corresponds to a 1 mm slip of steel strand in relation to concrete, and the ultimate bond strength initially increase and subsequently decrease at the inflection point of-80 ℃. The impact of the concrete strength on the bonding property, as shown by the tensile strength and the moisture content interaction, indicates that the bond stress vs concrete strength curve initially increases and later decreases with a decrease in temperature; the bond stress vs concrete cover thickness curve linearly increases, but the bond stress vs anchorage length curve linearly decreases at first and finally levels off.     

Transitions in Leisure Careers and Their Parallels in Work Careers: The Effect of Constraints on Choice and Action

Careers are increasingly characterized by multiple jobs and employers, and thus the issue of transitions between career components and through career stages is of greater importance than in the past. Transitions have also been extensively studied in the context of serious leisure. This paper uses findings from the literature on serious leisure and leisure constraints to develop propositions about the role of transitions in work careers and the effects that constraints have on transitions.     

Indigenous knowledge in environmental education processes: Perspectives on a growing research arena

What, then, is the problem? Indigenous knowledge has not, or not entirely disappeared from the collective memory. It has not lost any parcel of its age old efficiency either. Besides, it should not be considered a problem that it coexists today with so called modern science (i.e. an imported, supposedly rational system of knowledge and know-how). The real problem is elsewhere: about the very form of this coexistence. (Hountondji, 2002, p. 24, emphasis original)
