‘Put on your boots and Harrington!’: The ordinariness of 1970s UK punk dress
In 2013, the Metropolitan Museum hosted an exhibition of punk-inspired fashion entitled Punk: Chaos to Couture. The exhibition emphasized the ‘spectacular’ elements of the subculture, reflecting a narrative that dominates accounts of punk dress, whereby it is presented as a site of art school creativity and disjuncture with the past. This is an important aspect of punk dress, but photos of bands and audiences reveal that there was much more to British punk style in the 1970s than what was being sold on London’s King’s Road. Heeding calls to trouble the boundary between the spectacular and the ordinary in subculture studies, this article looks at the ordinariness of 1970s British punk dress, arguing that we should understand punk dress in terms of mass-market commodities, not just customization and designer fashion. Many of these commodities were worn by the skinheads who preceded punk, and this article explores this subcultural continuity by focusing on the role of the Dr.Marten boot and the Harrington jacketin first- and second-wave British punk dress.It does so through discussion of the Cockney Rejects, the 1979 BBC television dramatization of the Sham 69 album That’s Life and the Undertones.Peer reviewedFinal Accepted Versio
La veritat de la Viquipèdia
What does it mean to assert that Wikipedia has a relation to truth? That there is, despite regular claims to the contrary, an entire apparatus of truth in Wikipedia? In this article, I show that Wikipedia has in fact two distinct relations to truth: one which is well known and forms the basis of existing popular and scholarly commentaries, and another which refers to equally well-known aspects of Wikipedia, but has not been understood in terms of truth. I demonstrate Wikipedia’s dual relation to truth through a close analysis of the Neutral Point of View core content policy (and one of the project’s “Five Pillars”). I conclude by indicating what is at stake in the assertion that Wikipedia has a regime of truth and what bearing this has on existing commentaries
Branching rules in the ring of superclass functions of unipotent upper-triangular matrices
It is becoming increasingly clear that the supercharacter theory of the
finite group of unipotent upper-triangular matrices has a rich combinatorial
structure built on set-partitions that is analogous to the partition
combinatorics of the classical representation theory of the symmetric group.
This paper begins by exploring a connection to the ring of symmetric functions
in non-commuting variables that mirrors the symmetric group's relationship with
the ring of symmetric functions. It then also investigates some of the
representation theoretic structure constants arising from the restriction,
tensor products and superinduction of supercharacters in this context.Comment: 24 page
Should Aggregate Patient Preference Data Be Used to Make Decisions on Behalf of Unrepresented Patients?
Patient preference predictors aim to solve the moral problem of making treatment decisions on behalf of incapacitated patients. This commentary on a case of an
unrepresented patient at the end of life considers 3 related problems of such predictors: the problem of restricting the scope of inputs to the models (the “scope” problem), the problem of weighing inputs against one another (the “weight” problem), and the problem of multiple reasonable solutions to the scope and weight problems (the “multiple reasonable models” problem). Each of these problems poses challenges to reliably implementing patient preference predictors in important, high-stakes health care decision making. This commentary also suggests a way forward
Utilizing Imogolite Nanotubes as a Tunable Catalytic Material for the Selective Isomerization of Glucose to Fructose
The isomerization of glucose to fructose is an important step in the conversion of biomass to valuable fuels and chemicals. A key challenge for the isomerization reaction is achieving high selectivity towards fructose using recyclable and inexpensive catalysts. Imogolite is a single-walled aluminosilicate nanotube characterized by surface areas of 200-400 m2/g and pore widths near 1 nm. In this study, imogolite nanotubes are used as a heterogeneous catalyst for the isomerization of glucose to fructose. Catalytic testing demonstrates the catalytic activity of imogolite for the isomerization of glucose to fructose. Imogolite is a highly tunable structure and can be modified through substitution of Si with Ge or through functionalization of methyl groups to the inner surface. These modifications change the surface properties of the nanotubes and enable tuning of the catalytic performance. Aluminosilicate imogolite is the most active material for the conversion of glucose. Conversion of glucose of 30% and selectivity for fructose of 45% is achieved using aluminosilicate imogolite. Modification of imogolite with germanium or methyl groups decreases the conversion, but increases the selectivity. Generally, the selectivity for fructose decreases as the conversion of glucose increases. Interestingly, the imogolite nanotubes have comparable catalytic selectivity at similar conversion as base catalyzed reactions. Catalyst recycling experiments revealed that organic content accumulates on the nanotubes that results in a minor reduction in conversion while maintaining similar catalytic selectivity. Overall, imogolite nanotubes demonstrate an active and tunable catalytic platform for the isomerization of glucose to fructose.American Chemical Society Petroleum Research Fund (ACS-PRF 55946-DNI5)National Science Foundation (NSF CBET 1605037; 1653587 and NSF CBET REU 1645126)Ohio State University Institute of Materials Research (OSU IMR FG0138)The Undergraduate Research Office and Office of ResearchA one-year embargo was granted for this item.Academic Major: Chemical Engineerin
