Lesbian, gay, bisexual and transgender psychology:an international conversation among researchers

This article reports on a conversation between 12 lesbian, gay, bisexual and transgender (LGBT) psychologists at the first international LGBT Psychology Summer Institute at the University of Michigan in August 2009. Participants discuss how their work in LGBT psychology is affected by national policy, funding and academic contexts and the transnational influence of the US-based stigma model of LGBT psychology. The challenges and possibilities posed by internationalism are discussed with reference to the dominance of the United States, the cultural limits of terms such as 'lesbian, gay, bisexual and transgender', intergenerational communication between researchers and the role of events such as the Summer Institute in creating an international community of LGBT psychologists. © 2010 Taylor & Francis.

True chemical shift correlation maps:a TOCSY experiment with pure shifts in both dimensions

Signal resolution in H NMR is limited primarily by multiplet structure. Recent advances in pure shift NMR, in which the effects of homonuclear couplings are suppressed, have allowed this limitation to be circumvented in 1D NMR, gaining almost an order of magnitude in spectral resolution. Here for the first time an experiment is demonstrated that suppresses multiplet structure in both domains of a homonuclear two-dimensional spectrum. The principle is demonstrated for the TOCSY experiment, generating a chemical shift correlation map in which a single peak is seen for each coupled relationship, but the principle is general and readily extensible to other homonuclear correlation experiments. Such spectra greatly simplify manual spectral analysis and should be well-suited to automated methods for structure elucidation. © 2010 American Chemical Society.
