This paper argues that theorizations of the state which are sensitive to both its durability and its permeability, and theorizations which can account for the massive interconnections between local and global forces as well as different material and discursive sites are missing from contemporary work in the sociology of education. Drawing on Foucault's notion of 'governmentality' as a key resource for addressing this impasse, the authors highlight the constant fabrication of racial identity through the production of the pure space of racial origins or 'resentment'—the process of defining one's identity through the negation of the other. This dynamic, the article maintains, now informs key discourses both in popular culture and education. The authors conclude that these processes operate in tandem in the prosecution of the politics of racial exclusion in our times, informing key policy debates, including those around affirmative action and bilingual education.  相似文献

Using a mathematical procedure, we determine appropriate sampling rates for logging heart rate, at a variety of exercise intensities. The mathematical procedure involves correlating exercise and heart rate data to determine a dynamical mathematical model, from which the frequency response of the relationship between exercise intensity and heart rate can be determined. The sampling rate is then straightforwardly deduced by making appropriate measurements on the frequency response curve. We show how careful consideration needs to be given to the choice of dynamical model structure and the work regimen, so that consistent and convincing conclusions can be drawn. We demonstrate that the dynamics of the work-rate/heart-rate system are dependent on the nominal work/heart rate, but a 5-s sampling period, as used in many commercial heart rate monitors, appears to be adequate, especially when some averaging is performed before logging.  相似文献

In this study, we examined the effects of number of years of playing rugby on neck function. Active cervical spine range of motion and proprioception were assessed in 14 non-rugby-playing but trained sportsmen (mean age 28 years, s = 7) and 46 rugby players (26 rugby forwards: mean age 26 years, s = 5; mean years played 14 years; 20 backs: mean age 24 years, s = 5; mean years played 14 years). Active cervical range of motion in flexion, extension, left and right lateral flexion, plus left and right rotation were measured using a cervical range of motion device. The ability to reposition the head in a central position with eyes closed was taken as a measure of proprioception. Results show that rugby forwards generally had the least active cervical range of motion, particularly neck extension (forwards, 43 degrees ; backs, 55 degrees ; controls, 58 degrees ), with the decrement correlating with the number of years played. In addition, repositioning was significantly worse in rugby players after neck extension than non-rugby players (6 degrees vs. 3 degrees ). The active cervical range of motion of rugby forwards is similar to that of whiplash patients, suggesting that participation in rugby can have an effect on neck range of motion that is equivalent to chronic disability. Reduced active cervical range of motion could also increase the likelihood of injury and exacerbate age-related neck problems.  相似文献

Campus communities can be severely affected by a disaster. It is, therefore, important for counselors to establish contingencies for these unexpected events. The authors present a case study outlining specific outcomes of a natural disaster. Results showed that levels of anxiety and irritability declined significantly over the course of an academic year following the event. The Conservation Resources model is used as a framework for addressing the effects of a disaster.  相似文献
