Performing Absence as Intervention:The Case of Lee Lozano

The artist has long been understood in conventional Western art history, art criticism, and curatorial practice as the site of active agency, as the origin of the meaning and value of the work of art. By the later 20th century, during a period of social crisis across Europe and North America, however, theorists such as Roland Barthes and Jacques Derrida put pressure on this model. At the same time artists began mobilizing their agency in radically different ways as part of a broad societal challenging of Western hegemony, patriarchal and white dominant models of subjectivity, and structures of power more generally. Jones examines one extreme example of such a mobilization from the 1960s New York art world—the case of American artist Lee Lozano, who ostentatiously proclaimed her plan to &#8216;drop out&#8217; and leave this vibrant scene at the height of her career—to explore how artistic authorship itself could be seen as a key site for the interrogation of power in the world. The case of Lozano allows to pose the question: is a performance of withdrawal from art institutions the ultimate intervention in a period of social crisis? Or was she effectively &#8216;copping out&#8217; just at the moment when many of her colleagues (for example, in New York, feminists such as her friend Lucy Lippard, and the anti-racist protestors participating in the 1970 Art Strike) were publicly agitating on the streets and in the museums for equity and inclusion?

Her book entitled In Between Subjects: A Critical Genealogy of Queer Performance was published in 2021. Her current work addresses the structural racism and neoliberalism of the 21st century world of art and academia. Keynote Lecture in the context of the international Symposium ’Drafts in Action.

Composite two-generator links

AbstractNorwood showed that two-generator knots are prime and provided an example of a composite two-generator link of two components. Here a generalization of a theorem of Norwood shows that certain free products with amalgamation are not generated by any two group elements. This result is used to show that any composite two-generator link has Hopf link summand. The knot summmand is a two-generator knot in which one generator may be chosen to represent the class of a meridian

Al Lado, Afuera. // Beside, Outside.: The Performance of Solidarity between Archive and Repertoire in Guatemala and Canada

My research-creation dissertation investigates the question 'how are human rights enacted/performed? by examining solidarity activism in Guatemala and the hemispheric networks that enable it. The essay film al lado, afuera. // beside, outside. (2018, 21:12 min.), a synthesis of interviews with contemporary activists looks at human rights accompanimentthe process of situating oneself as an unarmed volunteer, assuming a physical presence alongside social activists who are victims of political threats, in order to dissuade violence, bear witness, and activate international solidarity networks. The performatic repertoire of accompaniment activism is explored upon the backdrop of the LAWG (Latin American Working Group)s collection of solidarity documents (1965-1997) and a large wall drawing that maps my research on networks of solidarity activism, thereby contextualizing this little-known embodied activist practice and exploring entanglements between the material archive and the ephemeral repertoire. Solidarity movement ephemera and a series of posters, created from graphic and textual elements of selected LAWG documents, highlight the material and historical foundation of todays accompaniment activism in Guatemala. By continuing to scan these documents in the gallery space as a durational performance throughout the exhibition, I highlight the labour performed in solidarity activism, and the change-of-state from paper materials to digital files, thereby mirroring of the trajectory from pre-Internet campaigns of letter-writing, information bulletins, flyers and posters, etcetera to todays digital forms of solidarity mobilization, and the various temporalities of solidarity. In transforming the collection from a material to a digital archive, I am creating an open source online repository of these crucial materials, as well as a gallery installation that highlights the aesthetics and materiality of pre-Internet solidarity activism, posing the question how does the materiality of solidarity evidenced in the LAWG collection work in tandem with embodied performances of solidarity activism

Trends of intervention for paediatric stone disease over the last two decades (2000–2015): A systematic review of literature

Objective: To ascertain the publication trends of interventions for paediatric kidney stone disease (KSD) we conducted a systematic review of literature over the last 16 years. Patients and methods: With a rise of paediatric KSD and related interventions, a systematic review using PubMed was done over the last 16 years for all published papers on ‘Paediatric stone disease intervention – ureteroscopy (URS), shockwave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), open stone surgery, and laparoscopic stone surgery’. The search was limited to English language articles with a published abstract, whilst case reports, animal and laboratory studies, were excluded. We also analysed the data in two time periods, period-1 (2000–2007) and period-2 (2008–2015). Results: During the last 16-years, 339 papers were published on paediatric stone disease intervention on PubMed. This included papers on URS (95), PCNL (97), SWL (102), open stone surgery (34) and laparoscopic stone surgery (11). During period-1 and period-2 there were 30 and 65 papers on URS, 16 and 81 papers on PCNL, 33 and 60 papers on SWL, nine and 25 papers on open surgery, respectively. When comparing the two periods, there were 92 published papers for all interventions in period-1 and this had risen almost threefold to 247 papers in period-2. Conclusions: Our systematic review shows that intervention for KSD in the paediatric age group has risen over the last 8 years. Whilst URS, SWL, open surgery and laparoscopic surgery have all doubled, PCNL has risen fivefold reflecting an increase in the new minimally invasive PCNL techniques

Modelling arterial thrombus formation in vitro

Purpose of reviewModels of arterial thrombus formation represent a vital experimental tool to investigate platelet function and test novel antithrombotic drugs. This review highlights some of the recent advances in modelling thrombus formation in vitro and suggests potential future directions.Recent findingsMicrofluidic devices and the availability of commercial chips in addition to enhanced accessibility of 3D printing has facilitated a rapid surge in the development of novel in-vitro thrombosis models. These include progression towards more sophisticated, 'vessel on a chip' models which incorporate vascular endothelial cells and smooth muscle cells. Other approaches include the addition of branches to the traditional single channel to yield an occlusive model; and developments in the adhesive coating of microfluidic chambers to better mimic the thrombogenic surface exposed following plaque rupture. Future developments in the drive to create more biologically relevant chambers could see a move towards the use of human placental vessels, perfused ex-vivo. However, further work is required to determine the feasibility and validity of this approach.SummaryRecent advances in thrombus formation models have significantly improved the pathophysiological relevance of in-vitro flow chambers to better reflect the in-vivo environment and provide a more translational platform to test novel antithrombotics

Le sexe et l’enseignement (de l’histoire de l’art)

Les débats sur la sexualité et le genre ont récemment resurgi avec force aux États-Unis à l’occasion de la controverse sur le mariage homosexuel et de l’irruption dans la culture de masse de sujets et de thèmes touchants au transgenre ; on songe sur ce dernier point notamment à la série télévisée Transparent, d’Amazon Studios, mettant en scène un homme d’âge mûr confronté au désarroi de ses enfants après avoir décidé de changer de sexe, à l’émission I am Cait, diffusée sur la chaîne E !, qui ..
