    The purpose of this project was to develop a resource manual to facilitate effective instructional strategies for at-risk junior high school students. To accomplish this purpose, current research and literature related to at-risk student characteristics, their special needs, and programs and strategies developed to assist them was reviewed. Additionally, on site visits to selected programs and interviews with teachers and administrators were conducted. At-risk students are young people who lack motivation to do well in school or work. They live marginally outside the socially accepted code for children and youth. School systems which have large numbers of at-risk students need to be flexible and creative in developing programs to meet the needs of these students. Parents and community members need to become knowledgeable and more involved with supporting programs for at-risk students

    Newsletter Networks in the Feminist History and Archives Movement

    Get PDF
    This article examines how networks have been critical to the construction of feminist histories. The author examines the publication Matrices: A Lesbian/Feminist Research Newsletter (1977–1996), to argue that a feminist network mode can be traced through the examination of small-scale print newsletters that draw on the language and function of networks. Publications such as Matrices emerge into wide production and circulation in the 1970s alongside feminist community archives, and newsletters and archives work together as interconnected social movement technologies. Newsletters enabled activist-researchers writing feminist histories to share difficult-to-access information, resources, and primary sources via photocopying and other modes of print reproduction.&nbsp; Looking from the present, the author examines how network thinking has been a feature of feminist activism and knowledge production since before the Internet, suggesting that publications such as Matrices are part of a longer history of networked communications media in feminist contexts

    Not the Truth We Seek: The Story of a Mime, Fierce Women, Proposals, & Pro Wrestling

    THE SPARK I have always believed that the best theater comes from a very real and sometimes very painful place. My parents were undergoing a brutal and very open separation and then divorce throughout my junior and senior year of high school. In the middle of the constant war zone that was our home, my brother and I would simply go from one room to the other with our heads down and as quick as possible. The only day we would linger in the living room would be Mondays. On Monday nights, my brother and I owned the living room as we would watch the three hour Monday Night RAW that is presented by the wrestling supergiant, World Wrestling Entertainment (WWE). This would be the defining thing that my brother and I could use to escape all the pain from the divorce. Little did I know that it would effect everything I do and believe when it comes to theater as an actor, a director, a choreographer, and a writer

    Simultaneous concentration and velocity maps in particle suspensions under shear from rheo-ultrasonic imaging

    No full text
    International audienceWe extend a previously developed ultrafast ultrasonic technique [T. Gallot , Rev. Sci. Instrum. 84, 045107 (2013)RSINAK0034-674810.1063/1.4801462] to concentration-field measurements in non-Brownian particle suspensions under shear. The technique provides access to time-resolved concentration maps within the gap of a Taylor-Couette cell simultaneously to local velocity measurements and standard rheological characterization. Benchmark experiments in homogeneous particle suspensions are used to calibrate the system. We then image heterogeneous concentration fields that result from centrifugation effects, from the classical Taylor-Couette instability, and from sedimentation or shear-induced resuspension

    Submitted to Physics of FluidsWe use X-ray imaging to study viscous resuspension. In a Taylor-Couette geometry, we shear an initially settled layer of spherical glass particles immersed in a Newtonian fluid and measure the local volume fraction profiles. In this configuration, the steady-state profiles are simply related to the normal viscosity defined in the framework of the Suspension Balance Model (SBM). These experiments allow us to examine this fundamental quantity over a wide range of volume fractions, in particular in the semi-dilute regime where experimental data are sorely lacking. Our measurements unambiguously show that the particle stress is quadratic with respect to the volume fraction in the dilute limit. Strikingly, they also reveal a nonlinear dependence on the Shields number, in contrast with previous theoretical and experimental results. This likely points to shear-thinning particle stresses and to a non-Coulomb or velocity-weakening friction between the particles, as also evidenced from shear reversal experiments
