A convenient regression formula for predicting Skytrax’s Official World Airport Star ratings

Skytrax audits and ranks airports internationally in its yearly ‘Official World Airport Star Ranking’. Unfortunately, its activity is severely restricted, at most covering just 3% of those airports listed by Skytrax as open to review by passengers in its website in 2010. This research article explored the possibility of using a readily available variable as predictor, as an alternative way of ranking the remaining 97% of airports in a simpler and more straightforward manner. The regression formula retained correlated highly with the criterion variable, accounting for 45% of its variance, thus supporting the viability of using customer reviews as a possible way of predicting ranking scores for airport not officially audited by Skytrax

Predicting Skytrax’s Official World Airline Star ratings from customer reviews

Skytrax audits and ranks airlines internationally in its yearly ‘Official World Airline Star Ranking’. Unfortunately, its activity is severely restricted, at most covering just 30% of those airlines listed as open for review by passengers in its website in 2010. This research article explored the possibility of using a readily available variable as predictor, as an alternative way of ranking the remaining 70% of airlines in a simpler and more straightforward manner. The regression formula retained correlated highly with the criterion variable, accounting for 47% of its variance, thus supporting the viability of using customer reviews as a possible way of predicting ranking scores for airlines not officially audited by Skytrax

Airline passengers’ rights to information and the strange case of the right to be informed about destinations

This research explored whether airline passengers wanted more rights to know about the safety and economic conditions of their flights, as well as the right to be reimbursed if they decided not to flight because of perceived risks. Overall, passengers agreed somehow on having more safety rights, but not so regarding financial rights. Surprisingly, they also wanted to have the right to be informed about their destinations (hotels, attractions, etc), something that is foreign to the purpose and duties of air transport

New technologies in general aviation

This research explored the technological needs of GA pilots at international levels. Overall, single pilot operators tend to value costs as the most important feature of any technology, followed by technology that helps with pre-flight tasks as well as during flight. Remote monitoring, post-flight analysis and 3-D displays are technological features of lesser importance

1975 Trials on doublegee

75A16, 75A17, 75C13, 75MO36, 75MO37, 75WH21, 75WH22. Biological control of doublegee

Longevity of doublegee seed under continuous pasture

Locality: Avondale, Wongan Hills and Chapman Research Stations. Background. Since 1974 pegged areas on the three research stations have been under continuous pasture and have been sampled annually to study the fate of the viable doublegee seed population. Each site was sprayed for doublegee control in the growing season before the first samples were taken in late summer of 73/74. The sites were again sprayed in the 1974 growing season except for Wongan Hills. The Wongan Hills site was cropped in 1976 and no further data is available. 74C7, 75WH65, 75WH66, 76AL11, 76C9, 76C6, 77C3, 77GE9, 77LC26, 77ME28, 77M028, 77N034, 77WH3

The effect of applied nitrogen and subterranean clover on the growth of doublegee

Until 20 years ago doublegees in Western Australia were mainly confined to the red-brown earth soils of the wheatbelt. Since then, they have spread to light loamy sand soils in the wheatbelt, many of which have carried subterranean clover from the mid-1940s onwards. It has been widely presumed that the spread of doublegees on to the lighter sandy soils of W.A. can be associated with the establishment of subterranean clover on these soils. This report summarises the results of a glasshouse experiment on the effect of clover and nitrogen on the growth of doublegee

Herbicides on tomato, capsicum and eggplant

SUMMARY Stomp controlled the widest range of weeds with a wide margin of crop tolerance. Recommend. 3 l/ha or lower before transplanting. Bensulide controlled grasses well, but did not control nightshade. Recommend 12 l/ha after transplanting. Lasso controlled a wide range of weeds, but the margin of selectivity is narrow. Recommended maximum 4 l/ha. Surflan controlled all weeds well, except nightshade, when applied after transplanting. The margin of selectivity is narrow on tomato and zero for nightshade. Recommend 1.5 1 after transplanting. Trifluralin controlled 3 weeds, and the margin of selectivity is narrow. Recommend rate of 4 l/ha. Trials - 80MD26, 80MD17, 80MD30, 80MD28, 80MD29
