During the liulf year ending January 31, 1911, there have been two groups of boys in a special class in Girard College, one group known as the "Retarded Class," the other as the "Delinquent Class." There were twenty-four boys in the Retarded Class and twenty-eight in the Delinquent Class. Retarded boys are those who have remained unduly long in a grade without promotion, the repeating having be...

in this paper, the temperature and annual precipitation data has been applied in 44 years for the synoptical stations northwest zone of iran. among the stations, eight of them, which have the perfect data and coverage, has been considered to analysis applied. in this study transfer function models have been used to analysis time series. in this method, firstly, the stations have been modeled th...

We prove that there is a one-to-one correspondence between selfdual metrics on 3CP of positive scalar curvature admitting a non-trivial Killing field but not being conformal to LeBrun metrics, and a class of normal quartic surfaces in CP whose equations can be explicitly written down. As a consequence, we show that the moduli space of these self-dual metrics on 3CP is non-empty and diffeomorphi...

BBOSWELL: Boswell: What I admire in Ramsay is his continuing to be so young. Johnson: Why yes sir, it is to be admired. I value myself upon this, that there is nothing of the old man in my conversation. I am now sixty-eight and I have no more of it than at twenty-eight. Boswell: But sir, would you not wish to know old age? He who is never an old man does not know the whole of human life; for ol...

[Purpose] The purpose of the study was to investigate the postural control and cognitive performance of older adults when stepping backward with and without a concurrent cognitive task. [Subjects and Methods] Thirty young adults and twenty-eight older adults (mean age=21.3 ± 1.2 and 72.2 ± 5.7 years, respectively) were recruited. Participants were asked to step backward and then maintain a sing...

This paper evaluates the role of collaborative learning in an Asian educational institution. The paper begins with a description of the current education landscape, particularly on learners of today which exhibit 21 century learning skills. The concept of collaborative learning is next described with an emphasis on Johnson and Johnson five key elements of collaborative learning. A research stud...
