“A Zone of Deep Shadow”: Pedagogical and Familial Reflections on “The Clash of Civilizations”

This paper examines the media coverage of the murder of a young Muslim girl in Mississauga, Ontario in December 2007. We examine how that coverage moved from concerns for a terrible family event to the use of the language of Samuel Huntington’s “Clash of Civilizations.” We explore the nature of this exaggeration that occurs in times of threat and the “hardening” and eventual clashing of identities that can follow. We interweave with these matters considerations of the pedagogical and familial consequences of such identity-exaggeration under threat. We propose that the provisional, negotiated, and casual conviviality of identities that precedes times of threat are cast into what Ivan Illich called “a zone of deep shadow.” We propose, also, that it is this locale of an interdependent, co-determining conviviality of identities that can profitably be the locus of rich and intellectually vital classroom conversations.

A numerical study of the Burgers’ equation

Time and space splitting techniques are applied to the Burgers’ equation and the modified Burgers’ equation, and then the quintic B-spline collocation procedure is employed to approximate the resulting systems. Some numerical examples are studied to demonstrate the accuracy and efficiency of the proposed method. Comparisons with both analytical solutions and some published numerical results are done in computational section.     

优秀羽毛球男子双打运动员第三拍技术的探讨

采用文献资料法、观察法、数理统计法等对新赛制下男子优秀羽毛球运动员的第3拍技术进行了研究,试图分析新规则实施后,当今世界顶尖男子双打选手如何根据接发球效果处理第3拍技术。研究结果表明:男子双打比赛中,当接发球主动时,第3拍的效果以一般居多,其次是被动;当接发球一般时,第3拍的效果则以一般为多数;当接发球被动时,第3拍的效果则以主动为多数。通过提高发球质量,研究对手的接发球规律,第3拍是可以争取主动的。     

Memories of Math: Visitors' Experiences in an Exhibiton about Calculus

Abstract Handling Calculus is a set of interactive exhibits about mathematics developed by the Science Museum of Minnesota and TERC. The exhibits are designed to engage visitors with kinesthetic, application‐oriented, and concept‐focused approaches to calculus and pre‐calculus concepts. As we examined visitor interviews collected during the evaluation of Handling Calculus, it was striking how often respondents' experiences with the exhibits stimulated memories they associated with school math. Respondents recognized math terms and symbols, reconstructed graphing skills, and recalled fragmentary concepts they had learned in school. In addition, they recounted stories about their former math teachers and the ways in which they had been taught mathematics, as well as a range of both positive and negative emotions they associated with school math. Respondents recognized and valued the hands‐on and whole‐body approaches used in Handling Calculus, contrasting the exhibits with their paper‐and‐pencil school experiences. Some respondents wondered if they would have done better at school calculus if their teachers had used the approaches taken by Handling Calculus.     

A multilevel hypernetworks approach to capture meso-level synchronisation processes in football

ABSTRACT

Understanding team behaviours in sports performance requires understanding the interdependencies established between their levels of complexity (micro-meso-macro). Previously, most studies examined interactions emerging at micro- and macro-levels, thus neglecting those emerging at a meso-level (reveals connections between player and team levels, depicted by the emergence of coordination in specific sub-groups of players–simplices during performance). We addressed this issue using the multilevel hypernetworks approach, adopting a cluster-phase method, to record player-simplice synchronies in two performance conditions where the number, size and location of goals were manipulated (first-condition: 6 × 6 + 4 mini-goals; second-condition: Gk + 6 × 6 + Gk). We investigated meso-level coordination tendencies, as a function of ball-possession (attacking/defending), field-direction (longitudinal/lateral) and teams (Team A/Team B). Generally, large synergistic relations and more stable patterns were observed in the longitudinal direction of the field than the lateral direction for both teams, and for both game phases in the first condition. The second condition displayed higher synchronies and more stable patterns in the lateral direction than the longitudinal plane for both teams, and for both game phases. Results suggest: (i) usefulness of hypernetworks in assessing synchronisation of teams at a meso-level; (ii) coaches may consider manipulating these task constraints to develop levels of local synchronies within teams.
