Coordinating Theory,Evidence, and Practice:

Concern about the harmful effects of industrial toxins has resulted in growing numbers of citizens fighting against toxic exposure in their communities. This paper describes key concepts derived from theories used to examine collective action in response to the threat of toxic exposure. These concepts are defined, synthesized into a theoretical framework, and illustrated. The framework provides an organizing perspective that social workers can use to respond to the problem of toxic exposure. The framework is one step toward advancing theory and research for organizing communities to respond to toxic exposure and other social problems when collective action is a viable response.     

Group sequential x2 statistic for testing the difference of two mean vectors in clinical trials

In this study we discuss the group sequential procedures for comparing two treatments based on multivariate observations in clinical trials. Also we suppose that a response vector on each of two treatments has a multivariate normal distribution with unknown covariance matrix. Then we propose a group sequential x² statistic in order to carry out repeated significance test for hypothesis of no difference between two population mean vectors. In order to realize the group sequential test where average sample number is reduced, we propose another modified group sequential x² statistic by extension of Jennison and Turnbull ( 1991 ). After construction of repeated confidence boundaries for making the repeated significance test, we compare two group sequential procedures based on two statistics regarding the average sample number and the power of the test in the simulations.     

An exact test for nbue class of survival functions

Let F(x) be a life distribution. An exact test is given for testing H₀ F is exponential, versusH₁Fε NBUE (NWUE); along with a table of critical values for n=5(l)80, and n=80(5)65. An asymptotic test is made available for large values of n, where the standardized normal table can be used for testing.     

Campus Walkability,Pedometer-Determined Steps,and Moderate-to-Vigorous Physical Activity: A Comparison of 2 University Campuses

Objective and Participants: At 2 Arizona State University (ASU) campuses, the authors measured student activity and distance walked on campus, as well as student-reported walkability around the student union. Methods: Students from ASU-Polytechnic (n = 20, 33% male) and ASU-Tempe (n = 20, 60% male) recorded distance walked on campus and wore physical activity monitors for 5 days. Results: Polytechnic students spent an average of 36.9 minutes in moderate-to-vigorous physical activity each week; Tempe students spent 69.5 minutes (p < .001). At Polytechnic, students walked an average of 7,674 steps per weekday; at Tempe, 11,294 steps (p = .003). Female students at Polytechnic walked an average of 1.3 km/d; at Tempe, 4.3 km/d (p < .001). At Polytechnic, men walked an average of 1.4 km/d; at Tempe, 3.1 km/d (p = .03). Tempe students rated campus walk-ability as very good, whereas Polytechnic students rated it fair (p < .001). Conclusions: Students at both campuses met activity recommendations; noted differences may be attributed to the built environment's contribution to walkability.     

理学统治地位的确立与元中期学风的转变

元代中叶科举考试的恢复，奠定了程朱理学的统治地位，从而引起了元代中期学术风气的变 化，这种变化主要有三个特点，即趋于正、趋于实、趋于古。这种学风，对元中期雅正文学 思潮的形成产生重大影响。
