The Spiral in the Tusk of the Narwhal

The spiral in the tusk of the narwhal has been fancifully, but never satisfactorily, explained. Spiral growths are common in the animal kingdom and share the feature of having straight axes.

The need to keep the tusk straight completely and satisfactorily explains the spiral.Key words: Monodon monoceros, dentition, morphology, asymmetryMots clés: Monodon monoceros, dentition, morphologie, asymétri

Super behaviour: a note on young Australian adults’ engagement with their superannuation accounts

We examine the behaviour and attitudes towards superannuation of 25-34 year old Australians. Our results suggest that they are generally uninterested in their superannuation accounts.

Overall the results suggest significant lack of interest in, and engagement and concern with issues related to their retirement planning

Superannuation knowledge, behaviour and attitudes in young adults in Australia

This report presents the results of a study examining superannuation knowledge, behaviour and attitudes in 994 young adult superannuation fund members (25-34 years old) in Australia. Respondents completed a 75 question online survey instrument which included questions on demographics and superannuation knowledge, behaviour and attitudes. It is the first large-scale study to focus exclusively on superannuation and the young adult population in Australia. The report concludes there are serious deficiencies in knowledge, behaviour and attitudes among young adults. Knowledge of basic facts about superannuation is poor. Young adults are unengaged by and uninterested in superannuation or retirement planning. Attitudes can be described as worried and skeptical
