“…Although the overall Pb-isotopic composition of the sputtered zircon and the bulk sample are identical under steady-state conditions (Shimizu and Hart 1982a), it is almost certain that the Pb isotopes within the ionised component (≤ 1% of all sputtered Pb atoms are ionised; Stern 1997, Williams 1998) are fractionated at some level. Isotopic fractionation in SIMS is controlled by a number of experimental factors, including the primary beam species and conditions, the composition of the sample, the sputter yield, the secondary ion mass and energy, and the ionisation probability of the particular element (e.g., Slodzian et al 1980, Shimizu and Hart 1982b, Benninghoven et al 1987).…”

“…The U and Pb contents (± 20%) were calibrated against SL13 zircon (238 μg g -1 U, 572 Ma). The 232 Th/ 238 U values (± 2%) were calculated using 248 ThO + / 254 UO + and session-specific Th/U discrimination factors determined from TEMORA 2 or QGNG (see Stern 1997 for details). Calibration of 206 Pb/ 238 U ratios was accomplished with either TEMORA 2 or QGNG utilising a power-law relation 206 Pb + / 238 U + = a x ( 254 UO + / 238 U + ) m , where the exponent m is measured or assumed for each session (2.0 ± 0.5; see Table 2).…”

An igneous zircon reference material (OG1) was characterised for U‐Pb isotopes by ID‐TIMS, and utilised to evaluate SIMS (SHRIMP) instrumental mass fractionation (IMF) of radiogenic Pb isotopes (207Pb*/206Pb*). The TIMS 207Pb*/206Pb* reference value for OG1 was 0.29907 ± 0.00011 (95% confidence limit), 3465.4 ± 0.6 Ma. The high 207Pb* (∼ 30 μg g−1), negligible common Pb, and isotopic homogeneity permitted precise (± 1–2‰) 207Pb*/206Pb* measurements within the analytical sessions. External reproducibility of mean 207Pb*/206Pb* ratios between sessions was demonstrated for one instrument, yielding a mean IMF of +0.87 ± 0.49‰. The mean 207Pb*/206Pb* ratios between instruments were dispersed beyond uncertainties, with session IMF values from +3.6 ± 1.7‰ to −2.4 ± 1.3‰, and a grand mean IMF value (twenty‐six sessions) of +0.70 ± 0.52‰, indicating a tendency towards elevated 207Pb*/206Pb*. The specific causes of variability in IMF are unclear, but generally reflect subtle differences in analytical conditions. The common practice in SIMS of assuming that IMF for Pb+ is insignificant could result in systematic age biases and underestimated uncertainties, of critical importance for precise correlation of Precambrian events. Nevertheless, a zircon RM such as OG1 can be readily incorporated into routine dating to improve 207Pb*/206Pb* accuracy and external reproducibility.

“…Regulatory independence, whether formal and based on statute or informal 'rules of the game' , can be a matter of degree. 21 For instance, there is evidence of UK regulators becoming more responsive to political concerns over time. 22 There can be a number of reasons to structure a regime that has decisions being made by an independent agency, such as specialist expertise for efficient implementation, policy independence from political influence, credible commitment to consistent decision-making over a longer time horizon than many political decisions, and trading off various types of transaction cost (such as political decision-making, commitment, agency, and uncertainty).…”

Spectrum Auctions: Designing markets to benefit the public, industry and the economy

Access to the radio spectrum is vital for modern digital communication. It is an essential component for smartphone capabilities, the Cloud, the Internet of Things, autonomous vehicles, and multiple other new technologies. Governments use spectrum auctions to decide which companies should use what parts of the radio spectrum. Successful auctions can fuel rapid innovation in products and services, unlock substantial economic benefits, build comparative advantage across all regions, and create billions of dollars of government revenues. Poor auction strategies can leave bandwidth unsold and delay innovation, sell national assets to firms too cheaply, or create uncompetitive markets with high mobile prices and patchy coverage that stifles economic growth. Corporate bidders regularly complain that auctions raise their costs, while government critics argue that insufficient revenues are raised. The cross-national record shows many examples of both highly successful auctions and miserable failures. Drawing on experience from the UK and other countries, senior regulator Geoffrey Myers explains how to optimise the regulatory design of auctions, from initial planning to final implementation. Spectrum Auctions offers unrivalled expertise for regulators and economists engaged in practical auction design or company executives planning bidding strategies. For applied economists, teachers, and advanced students this book provides unrivalled insights in market design and public management. Providing clear analytical frameworks, case studies of auctions, and stage-by-stage advice, it is essential reading for anyone interested in designing public-interested and successful spectrum auctions.

“…Indeed, as Julia Stern puts it, 'the reproduction of mothering' makes up the major subject of the novel. 51 But Eliza's motherhood is manifested mostly and primarily through her pregnancy, which makes her a potential mother more than a mother within the narrative. This somewhat oblique connection with motherhood, I argue, makes The Coquette an even more interesting literary example, one that illustrates the entangled political and material consequences of motherhood.…”

Coquettish Mothers across the Atlantic: Gendered Liberty, Disciplinary Sexuality and Colonial Productivity in Lady Susan and The Coquette

This article reads Jane Austen's Lady Susan alongside Hannah Webster Foster's The Coquette in the context of the shifting British colonial relationship with America. I present the coquettish mother as a historically significant literary figure who embodies the rival claims of Enlightenment liberty and the necessity to control national (re-)production via an exploitative, colonial logic that enables ideological formations of domesticity. My analysis of the socially corrective drive captured in these novels suggests that British anxiety over the loss of the American colonies prompted an urgent and ongoing effort to redefine productivity by obscuring the economic consequences of female sexuality.
