humane treatment, that will leave readers so disheartened. Optimism and conviction give way to despair and backtracking. Private madhouses, once excoriated by the public asylum "masters", are eventually but grudgingly endorsed. Medical treatments, avowedly eschewed in favour of moral treatment, are similarly embraced in time. The authors' cautionary tale of unbridled faith in institutionalizati...

South Cascade Glacier mass balance , 1935 – 2006

A simple model uses daily observations of precipitation and temperature at a nearby weather station to estimate glacier-average seasonal mass-balance components at South Cascade Glacier, Washington, USA, from 1935, 24 years before measurements began at the glacier. This is 13 years earlier than measurements that can be derived using the NCEP–NCAR reanalysis database (begins 1 January 1948). Alt...

(ii) idRn ∈ G, recall idRnT = T = T idRn for any T ∈ G (iii) If T ∈ G, then T is bijective and T−1 ∈ G Proof. (i) and (ii) are fairly easy exercises. For (iii), we have that T ∈ G is surjective by definition, so only need to check one to one. For x,y ∈ R, Tx = Ty =⇒ 0 = ‖Tx−Ty‖ = ‖x−y‖ =⇒ x = y. So T is bijective, and T−1 is surjective. T−1 is an isometry since for x,y ∈ R, ‖T−1x− T−1y‖ = ‖TT−1...
