Extending Responsiveness to Intervention to Mathematics at First and Third Grades

Responsiveness to intervention (RTI) is an innovative approach to the identification of learning disabilities (LD). The central assumption is that RTI can differentiate between two explanations for low achievement: poor instruction versus disability. If the child responds poorly to validated instruction, then the assessment eliminates instructional quality as a viable explanation for poor academic growth and instead provides evidence of a disability. For children who do respond nicely, RTI serves a critical prevention function. Most of RTI research has been focused on early reading. In this article, we describe two ongoing programs of research on RTI in the area of mathematics: one on a comprehensive mathematics curriculum at first grade and the other focused on word problems at third grade. For each research program, we describe the sample, explain how students are identified as at risk for mathematics disability, provide an overview of the interventions to which responsiveness is gauged, and describe some results to date.     

Braided composite materials for the production of lightweight, high rigidity golf shafts

Braiding is not currently used in the production of golf shafts. The objective of this work was to develop, through a modelling process consisting of altering lamina sequence, a golf shaft, using braided laminas, which would have mass, stiffness and torque comparable to commercially available composite and steel shafts. A 2D conical braided composite model was previously developed and validated to predict elastic constants of braided closed meshed structures. Energy methods were used to calculate the stiffness and torque of shafts using prescribed industry approaches. Shaft mass was calculated based on geometry and density of constitutent materials. Modelled shafts had both braided and unidirectional layers and compared favourably with or were better than commercially available composite and steel shafts in terms of deflection force and twist angle; they had the same weight as composite shafts but were much lighter than steel shafts. If these findings are verified, braided composites would be a viable and effective approach to the design of future golf shafts.     

‘Muscles for Motherhood’: A Genealogical Analysis of Medicalized Ways of Knowing Female Footballers in New Zealand, 1921 and 1973–1975

ABSTRACT

Michel Foucault argued that females gradually became integrated into the sphere of medical practices through a process which he termed as a ‘hysterization of women’s bodies’ (Foucault, The History of Sexuality, Volume One: An Introduction, New York: Pantheon Books, 1978, 104). In this article, we draw on Foucault to examine how women’s bodies, exercise and motherhood impacted on the historical development of female football in New Zealand within two time periods (1921 and 1973–1975). Employing his genealogical framework, we analyze newspaper reports, historical documents and conducted in-depth interviews to demonstrate how medical/scientific discourses both constrained and enabled the participation of women in football. We conclude that while medical knowledge was used to publicly disqualify the legitimacy of the female footballer in 1921, and hence her abrupt disappearance from the sporting realm, the absence of such medical knowledge in the early 1970s, combined with societal changes associated with second wave feminism, paved the way for the eventual ‘normalization’ of female football in New Zealand.     

心的中心地位:道家之间的论战

心与身体其他感觉器官的关系问题,备受先秦两汉所有重要思想流派的争议。众所周知,传统儒家认为心是主"情"的器官,并具有分析其他感官之间差异的能力1。对于孟子来说,"四端"学说就是关于"心"的内容,最为显著的是恻隐之心,它能促进人们德性的成长2。对于儒家来说,与其他自然的感觉器官相比,"心"是较为高级的。因为它不仅具有思考的能力,而且能评估人们所遇之事;而其他感知器官,仅仅是在于接触其他事物3。"心"比其
