    Retelling racialized violence, remaking white innocence: the politics of interlocking oppressions in transgender day of remembrance

    Transgender Day of Remembrance has become a significant political event among those resisting violence against gender-variant persons. Commemorated in more than 250 locations worldwide, this day honors individuals who were killed due to anti-transgender hatred or prejudice. However, by focusing on transphobia as the definitive cause of violence, this ritual potentially obscures the ways in which hierarchies of race, class, and sexuality constitute such acts. Taking the Transgender Day of Remembrance/Remembering Our Dead project as a case study for considering the politics of memorialization, as well as tracing the narrative history of the Fred F. C. Martinez murder case in Colorado, the author argues that deracialized accounts of violence produce seemingly innocent White witnesses who can consume these spectacles of domination without confronting their own complicity in such acts. The author suggests that remembrance practices require critical rethinking if we are to confront violence in more effective ways.

    Community profiling and gene expression of fungal assimilatory nitrate reductases in agricultural soil

    Although fungi contribute significantly to the microbial biomass in terrestrial ecosystems, little is known about their contribution to biogeochemical nitrogen cycles. Agricultural soils usually contain comparably high amounts of inorganic nitrogen, mainly in the form of nitrate. Many studies focused on bacterial and archaeal turnover of nitrate by nitrification, denitrification and assimilation, whereas the fungal role remained largely neglected. To enable research on the fungal contribution to the biogeochemical nitrogen cycle tools for monitoring the presence and expression of fungal assimilatory nitrate reductase genes were developed. To the ∼100 currently available fungal full-length gene sequences, another 109 partial sequences were added by amplification from individual culture isolates, representing all major orders occurring in agricultural soils. The extended database led to the discovery of new horizontal gene transfer events within the fungal kingdom. The newly developed PCR primers were used to study gene pools and gene expression of fungal nitrate reductases in agricultural soils. The availability of the extended database allowed affiliation of many sequences to known species, genera or families. Energy supply by a carbon source seems to be the major regulator of nitrate reductase gene expression for fungi in agricultural soils, which is in good agreement with the high energy demand of complete reduction of nitrate to ammonium

    Polyamory: Intimate practice, identity or sexual orientation?

    Polyamory means different things to different people. While some consider polyamory to be nothing more than a convenient label for their current relationship constellations or a handy tool for communicating their willingness to enter more than one relationship at a time, others claim it as one of their core identities. Essentialist identity narratives have sustained recent arguments that polyamory is best understood as a sexual orientation and is as such comparable with homosexuality, heterosexuality or bisexuality. Such a move would render polyamory intelligible within dominant political and legal frameworks of sexual diversity. The article surveys academic and activist discussions on sexual orientation and traces contradictory voices in current debates on polyamory. The author draws on poststructuralist ideas to show the shortcomings of sexual orientation discourses and highlights the losses which are likely to follow from pragmatic definitions of polyamory as sexual orientation
