Time Taken as a Determinant of Advancement in Shotokan Karate Black-Belt Tekki Kata Performance
18 experienced black-belt subjects were individually timed on the kata Tekki Shodan. A significant relationship was found between years training and increased performance time and also between increased performance time and grade, both independent of age.
Time Taken as a Determinant of Advancement in Shotokan Karate Black-Belt Heian Kata Performance
30 experienced black-belt subjects were individually timed on each of the five Heian kata. Significant relationships were found between years of training and increased performance time on all the kata and for four with age controlled. The multiple correlation was significant.
AN INTRODUCTION T O THE SOILS OF THE SOUTH-EASTERN PORTION OF THE AUSTRALIAN ARID ZONE
Summary 
 
Seven soil regions, each of which is dominated by soils belonging to one or two great soil groups, are defined and mapped. The outstanding feature is the presence of a variety of soils with widely differing characteristics. The soils are deeper, have more profile differentiation and are finer-extured than those in most-arid regions and are frequently overlain by currently-forming deposits of wind-transported materials. Because the vegetative cover is better developed and there are only small areas of rocky hills and bare rock pediments, water erosion and deposition are not as prominent as in other arid areas.
