For the first time in the history of the American Jewish community, delegates from all corners of the country and from all groupings in Jewish life gathered at a national conference on January 13–14, 1951 to discuss not fundraising and philanthropy, not emergencies and responsibilities overseas, not even the frequently raised spector of anti-Semitism, but Jewish education. 相似文献

Bicycle suspensions aim to improve riding performance and rider comfort through reduced impact and vibration transmission
to frame and rider. This study compared vibration damping of five mountain bike suspension systems and a rigid fork on gravel
and in trail conditions by quantifying accelerations at the axle and frame. Spectral analyses of the acceleration signals
revealed two distinct frequency regions from 0 to about 100 Hz and from about 300 to 400 Hz. The various suspension systems
were all effective in attenuating vibration over the low frequency region. Vibration amplitudes at the frame were considerably
less than at the axle for the suspension conditions (30–60% reduction) while only minor attenuation was observed with the
rigid fork (10–15%). In the high frequency region between 300–400 Hz, the signal was strongly attenuated at the frame for
all conditions, including the rigid fork. Trail conditions elicited greater amplitude low frequency vibrations than did gravel
conditions. While all suspension systems were somewhat effective in reducing vibration of the frame, air-oil forks had significantly
better vibration attenuation than did elastomer or linkage systems. 相似文献

With the fall of communism in 1989, Eastern and Central Europe would quickly become part of an already strong global tide of privatization in higher education. Nowhere else did private higher education rise so suddenly or strongly from virtual nonexistence to a major regional presence. A fresh database allows us to analyze the extent and dimensions of that presence, including various national and subregional quantitative dimensions. Yet the private sector is strongly challenged on several fronts, including paradoxically by the public sector’s own partial privatization, sometimes closely linked to the private-sector growth. Nonetheless, private higher education has continued to grow thus far into the new century, with shifting national and subregional patterns. Higher education privatization remains a noteworthy reality in Eastern and Central Europe but it is an evolving reality. 相似文献

The primary purpose of the present paper is to call attention to Hawkins’ (4) procedure for testing a sequence of observations for a shift in location. Such a procedure could have applicability for assessing change within a single subject. Monte Carlo results are provided which suggest that Hawkins’ procedure is robust with respect to moderate violations of its underlying assumptions of homogeneity of variance and normality. A hypothetical example is also discussed for illustrative purposes. 相似文献

Abstract A computer based simulation model that traces the recreational use patterns within park and wilderness areas has been employed as a teaching tool in a recreation management course at the University of Vermont. Use of the Wilderness Travel Simulation Model in the classroom reduces the complexity of the system under study, allows students to act as managers (devising and testing their own management strategies), and increases the students' exposure to the characteristics of an actual park or wilderness area. The value of the model as a teaching tool was supported by the students' high degree of interest and enthusiasm in the class. 相似文献

The purpose of this study was to investigate attitudes of intercollegiate student athletes regarding their use of counseling services. The authors assessed student athletes’ perceived barriers to seeking counseling services and their preferred characteristics of a helping professional. Several barriers to counseling were identified. Results suggest student athletes have strong preferences for counselor characteristics, including familiarity with sports, gender, and age. Practical applications of these findings are discussed. 相似文献
