New insight into BRST anomalies in superstring theory

Based on the extended BRST formalism of Batalin, Fradkin and Vilkovisky, we perform a general algebraic analysis of the BRST anomalies in superstring theory of Neveu-Schwarz-Ramond. Consistency conditions on the BRST anomalies are completely solved. The genuine super-Virasoro anomaly is identified with the essentially unique solution to the consistency condition without any reference to a particular gauge for the 2D supergravity fields. In a configuration space where metric and gravitino fields are properly constructed, general form of the super-Weyl anomaly is obtained from the super-Virasoro anomaly as its descendant. We give a novel local action of super-Liouville type, which plays a role of Wess-Zumino-Witten term shifting the super-Virasoro anomaly into the super-Weyl anomaly. These results reveal a hierarchial relationship in the BRST anoamlies.Comment: 29 pages, PHYZZ

Engaging Hashima: Memory Work, Site-Based Affects, and the Possibilities of Interruption

How is memory embodied, narrated, interrupted, and reworked? Here, we take a postphenomenological approach to memory work that is attentive to how site-based affects prompt and ossify, but also transmogrify, memory of place. With reference to an intensely traumatized, but also domesticated and entropied, environment—the island of Hashima, off the coast from Nagasaki City in Japan—we demonstrate the relevance and explanatory reach of culturally specific accounts of memory, time, and place; how an attentiveness to cultural context in the making of meaning helps mark out the epistemological violences that accrue around sites such as Hashima as objects of analysis in and of themselves; and the affective capacities of the materialities and forces that compose such sites, which can present a welter of surfaces and interiorities that are sensuously “felt” as memory

The low-turbulence wind tunnel at Tōhoku University

SummaryA general-purpose low turbulence wind tunnel was constructed using the design method of Bradshaw. Sound absorbent material was used in every four corners to decrease sound intensity produced by a fan. The longitudinal component of turbulence intensity at the centre of the closed working section is less than 0.02% of the mean velocity in the speed range between 18 m/s arid 53 m/s. The mean velocity variations across the working section are within ±0.1% of the mean velocity.Performance measurements have been done at representative tunnel cross sections to clarify the behaviour of flow in the tunnel. This work differs from previous studies in the sense that emphasis is placed not only on velocity distributions, but also on turbulence intensity distributions at several cross sections of the tunnel.The critical Reynolds number for a flat plate at zero incidence, Rec = 3.5 x 106, measured in a stream of the very low turbulence intensity of 0.016%, is larger than that reported by Schubauer and Skramstad.</jats:p

‘I’d rather work in a supermarket’: privatization of home care work in Japan

The rise in nuclear family households and more married women engaging in paid work have forced governments to address the issue of aged care for the elderly to a greater degree. A good illustration is home care in Japan where the government introduced a Long Term Care Insurance scheme (LTCI) (2000) focused on offering affordable almost universal care by extending existing home care services. Japan's home care services were privatized in 2006 and, while this is not unique to Japan, the combination of cost-cutting measures and the client-driven model encompassed in the LTCI has had a significant impact on employment conditions and the organization of work in home care services. This research assesses the impact on employment conditions and the organization of work in Japan's former government-run home care sector compared with the pre-LTCI period and argues that privatization has resulted in work intensification and deteriorating employment conditions.Griffith Business School, Dept of Employment Relations and Human ResourcesFull Tex
