So, Where Is Queer? A Critical Geography Of Queer Exhibitions In Australia, Andrew W. Gorman-Murray Jan 2008

So, Where Is Queer? A Critical Geography Of Queer Exhibitions In Australia, Andrew W. Gorman-Murray

This paper interrogates the geography of queer exhibitions in museums and galleries in Australia. The analysis draws on data from Museums Australia's database of queer exhibitions (1982-2005), which are cross-tabulated with geographical variables such as location, scale and state/territory population. The findings show an uneven geographical distribution of exhibitions, how geography also frames the themes of queer exhibitions, and an imbalanced geography, in which regional histories are few, national and state scale histories are prevalent, and minimal exhibitions occur outside metropolitan areas. This is problematic because queer identities, communities and histories vary across scales and between places. Appreciation of geography …

Ions formed from lipids during electrospray ionization of crude lipid extracts have been mass-selected within a quadrupole linear ion trap mass spectrometer and allowed to react with ozone vapor. Gas-phase ion−molecule reactions between unsaturated lipid ions and ozone are found to yield two primary product ions for each carbon−carbon double bond within the molecule. The mass-to-charge ratios of these chemically induced fragments are diagnostic of the position of unsaturation within the precursor ion. This novel analytical technique, dubbed ozone-induced dissociation (OzID), can be applied both in series and in parallel with conventional collision-induced dissociation (CID) to provide near-complete structural assignment …
