    Description: This unique book presents a new perspective on citizenship by treating it as a continuing focus of dispute. The authors develop a view of citizenship as always emerging from struggle through an exploration of the entanglements of politics, culture and power that are both embodied and contested in forms and practices of citizenship. This book will mainly appeal to scholars and students engaged by the question of citizenship, across a range of disciplines, as well as policymakers and practitioners.

    Description: The book presents a novel examination of urban commons which provides a robust base for education initiatives and future public policy guidance on the protection and use of urban commons as invaluable urban green spaces that offer a diverse cultural and ecological resource for future communities. The book's central argument is that only through a deep understanding of the past and a rigorous engagement with present users, can we devise new futures or imaginaries of culture, well-being and diversity for the urban commons. It argues that understanding the genesis of, and interactions between, the different pressures on urban green space has important policy implications for the delivery of nature conservation, recreational access and other land use priorities. The stakeholders in today’s urban commons, whether land users, policy makers or the public, are the inheritors of a complex cultural legacy and must negotiate diverse and sometimes conflicting objectives in their pursuit of a potentially unifying goal: a secure future for our urban commons. The book offers a unique and strongly interdisciplinary study of urban commons, one that brings together original historical investigation, contemporary legal scholarship, extensive oral history research with user groups, and research examining the imagined futures for the urban common in modern society. It explores the complex social and political history of the urban common, as well as its legal and cultural status today, using four diverse case studies from within England as exemplars of the distinctively urban common. These are Town Moor in Newcastle, Mousehold Heath in Norwich, Clifton and Durdham Downs in Bristol and Valley Gardens in Brighton. The book concludes by looking forward and considering new tools and methods of negotiation, inclusivity and creativity to inform the future of these case studies, and of urban commons more widely. This book will be of great interest to students and scholars of the commons, green spaces, urban planning, environmental and urban geography, environmental studies and natural resource management.

    Description: This paper is not subject to U.S. copyright. The definitive version was published in Marine Geology 329-331 (2012): 34-45, doi:10.1016/j.margeo.2012.09.006.
    Description: Pockmark fields occur throughout northern North American temperate estuaries despite the absence of extensive thermogenic hydrocarbon deposits typically associated with pockmarks. In such settings, the origins of the gas and triggering mechanism(s) responsible for pockmark formation are not obvious. Nor is it known why pockmarks proliferate in this region but do not occur south of the glacial terminus in eastern North America. This paper tests two hypotheses addressing these knowledge gaps: 1) the region's unique sea-level history provided a terrestrial deposit that sourced the gas responsible for pockmark formation; and 2) the region's physiography controls pockmarks distribution. This study integrates over 2500 km of high-resolution swath bathymetry, Chirp seismic reflection profiles and vibracore data acquired in three estuarine pockmark fields in the Gulf of Maine and Bay of Fundy. Vibracores sampled a hydric paleosol lacking the organic-rich upper horizons, indicating that an organic-rich terrestrial deposit was eroded prior to pockmark formation. This observation suggests that the gas, which is presumably responsible for the formation of the pockmarks, originated in Holocene estuarine sediments (loss on ignition 3.5–10%), not terrestrial deposits that were subsequently drowned and buried by mud. The 7470 pockmarks identified in this study are non-randomly clustered. Pockmark size and distribution relate to Holocene sediment thickness (r2 = 0.60), basin morphology and glacial deposits. The irregular underlying topography that dictates Holocene sediment thickness may ultimately play a more important role in temperate estuarine pockmark distribution than drowned terrestrial deposits. These results give insight into the conditions necessary for pockmark formation in nearshore coastal environments.

    Notes: Computer models are presented for a microstrip amplifier based on a dc superconducting quantum interference device (SQUID). In this device, the signal is applied between one end of the spiral input coil and the square washer on which it is deposited. The amplifier exhibits substantial power gain when the signal frequency is such that a half wavelength is approximately equal to the length of the microstrip formed by the coil and the groundplane. The resonant frequency is lowered significantly by the inductance of the square washer transformed into the input coil; this reduction is consistent with predictions of a simple model and with analog simulations. With the washer grounded, the gain of the amplifier peaks at a frequency that is lowered from the unloaded resonant frequency by the damping of the resistance associated with the source. The position and magnitude of the peak are in good agreement with both a lumped circuit model and with a model representing the microstrip as a transmission line. When the counter electrode of the SQUID is grounded and the washer floats, feedback from the output of the SQUID to the input via the capacitance of the microstrip plays a major role and is well described by simulations using the transmission line model. Measurements of the input impedance of the microstrip amplifier show that the return loss can be positive or negative, depending on the sign of the feedback and whether the frequency is above or below the resonant frequency. This behavior is in good accord with simulations. © 2000 American Institute of Physics.

    Notes: We describe a high transition temperature superconducting, first-order gradiometer intended for biomagnetic measurements in an unshielded environment. The gradiometer involves a single-layer, planar flux transformer with two loops of unequal size, the smaller of which is inductively coupled to the pickup loop of a directly coupled magnetometer. In this configuration, the presence of the flux transformer reduces the sensitivity of the magnetometer by only about 5%. The flux transformer is patterned in a thin film of YBa2Cu3O7−δ deposited on a 100 mm diam wafer, and has a baseline of 48 mm. The flux transformer and magnetometer substrates are permanently bonded together in a flipchip arrangement. The common mode rejection of uniform magnetic field fluctuations in any direction is better than 1 part per 100. The outputs of two such gradiometers are subtracted to form a second-order gradiometer, which rejects first-order gradient fluctuations to about 1 part in 100. With the aid of three orthogonally mounted magnetometers, one can reduce the response of the gradiometers to uniform field fluctuations to below 100 ppm. This system is used to detect magnetic signals from the human heart in an unshielded environment. © 2000 American Institute of Physics.

    Notes: A spectrometer based on a dc superconducting quantum interference device (SQUID) has been developed for the direct detection of nuclear magnetic resonance (NMR) or nuclear quadrupole resonance (NQR) at frequencies up to 5 MHz. The sample is coupled to the input coil of the niobium-based SQUID via a nonresonant superconducting circuit. The flux locked loop involves the direct offset integration technique with additional positive feedback in which the output of the SQUID is coupled directly to a low-noise preamplifier. Precession of the nuclear quadrupole spins is induced by a magnetic field pulse with the feedback circuit disabled; subsequently, flux locked operation is restored and the SQUID amplifies the signal produced by the nuclear free induction signal. The spectrometer has been used to detect 27Al NQR signals in ruby (Al2O3[Cr3+]) at 359 and 714 kHz. © 1996 American Institute of Physics.

    Notes: We describe the design and construction of a single-coil, two-channel probe for the detection of low-field magnetic resonance using dynamic nuclear polarization (DNP). The high-frequency channel of the probe, which is used to saturate the electron spins, is tuned to the electron Larmor frequency, 75 MHz at 2.7 mT, and matched to 50 Ω. Low-field, 1H nuclear magnetic resonance (NMR) is detected through the second, low-frequency channel at frequencies 〈1 MHz. The performance of the probe was tested by measuring the DNP of protons in a manganese (II) chloride solution at 2.7 mT. At the proton NMR frequency of 120 kHz, the signal amplitude was enhanced over the value without DNP by a factor of about 200. © 1997 American Institute of Physics.

    Notes: A microscope has been constructed in which a high-transition temperature dc superconducting quantum interference device (SQUID) in vacuum is brought to within 140 μm of samples at room temperature and pressure. The SQUID is mounted on the upper end of a sapphire rod, cooled to liquid nitrogen temperature, below a 75-μm thick sapphire window. Samples can either be placed directly on the window or scanned over the SQUID to produce magnetic images. A square-washer SQUID with inner and outer dimensions of 30 and 50 μm can resolve 130 μm magnetic features. The instrument is intended primarily for biological applications. © 1996 American Institute of Physics.
