Wives,Children … Husbands: Supporting Roles

In 1965, Hugo L. Black asked his wife, Elizabeth, to host a dinner party. The purpose: to help him persuade Carolyn Agger, wife of Washington attorney Abe Fortas, to allow her husband to accept President Lyndon B. Johnson's offer of a seat on the Supreme Court. A tax lawyer at the same firm as Fortas, Agger was displeased that the move would mean a big cut in his salary; she thought he should spend a few more years in his lucrative private practice before becoming a judge. After all, he was only fifty‐five. Elizabeth Black described the tense occasion in a diary entry:     

Solubility of corundum + kyanite in H2O at 700°C and 10 kbar: evidence for Al‐Si complexing at high pressure and temperature

The solubility of the assemblage corundum + kyanite in H₂O was determined at 700°C and 10 kbar, using a piston‐cylinder apparatus and rapid‐quench/fluid‐extraction techniques. Weighted mean concentrations of total Al and Si were 5.80 ± 0.03 mmol kg^?1 H₂O and 0.308 ± 0.003 mol kg^?1 H₂O, respectively (1σ errors). The Al concentration is nearly five times higher than that of corundum solubility in pure H₂O. This difference is interpreted to arise from complexing between Si and Al to form HAlSiO_4,aq species. Charged or more polymerized species are also possible, but their abundance cannot be constrained based on these experiments. Assumption of a single aqueous aluminosilicate complex permits calculation of the thermodynamic consequences of Al‐Si interaction in high‐pressure fluids, as well as phase diagrams for the system Al‐Si‐O‐H. Formation of Al‐Si complexes leads to a large increase in dissolved Al with increasing Si in solution, such that Al concentration in equilibrium with kyanite + quartz is predicted to be 7.1 mmolal, higher than with kyanite + corundum. The elevated concentration of Si in deep‐crustal and mantle aqueous fluids suggests that Al must readily be dissolved and transported by Al‐Si complexing in high‐pressure metamorphic and metasomatic environments. The results provide a simple explanation for the common observation of kyanite + quartz segregations in eclogites and Barrovian metamorphic rocks.     

Hydraulic observations from a 1 year fluid production test in the 4000 m deep KTB pilot borehole

A long‐term pump test was conducted in the KTB pilot borehole (KTB‐VB), located in the Oberpfalz area, Germany. It produced 22 300 m³ of formation fluid. Initially, fluid production rate was 29 l min^?1 for 4 months, but was then raised to an average of 57 l min^?1 for eight more months. The aim of this study was to examine the fluid parameters and hydraulic properties of fractured, crystalline crusts as part of the new KTB programme ‘Energy and Fluid Transport in Continental Fault Systems’. KTB‐VB has an open‐hole section from 3850 to 4000 m depth that is in hydraulic contact with a prominent continental fault system in the area, called SE2. Salinity and temperature of the fluid inside the borehole, and consequently hydrostatic pressure, changed significantly throughout the test. Influence of these quantities on variations in fluid density had to be taken into account for interpretation of the pump test. Modelling of the pressure response related to the pumping was achieved assuming the validity of linear Darcy flow and permeability to be independent of the flow rate. Following the principle ‘minimum in model dimension’, we first examined whether the pressure response can be explained by an equivalent model where rock properties around the borehole are axially symmetric. Calculations show that the observed pressure data in KTB‐VB can in fact be reproduced through such a configuration. For the period of high pumping rate (57 l min^?1) and the following recovery phase, the resulting parameters are 2.4 × 10^?13 m³ in hydraulic transmissivity and 3.7 × 10^?9 m Pa^?1 in storativity for radial distances up to 187 m, and 4.7 × 10^?14 m³ and 6.0 × 10^?9 m Pa^?1, respectively, for radial distances between 187 and 1200 m. The former pair of values mainly reflect the hydraulic properties of the fault zone SE2. For a more realistic hydraulic study on a greater scale, program FEFLOW was used. Parameter values were obtained by matching the calculated induced pressure signal to fluid‐level variations observed in the KTB main hole (KTB‐HB) located at 200 m radial distance from KTB‐VB. KTB‐HB is uncased from 9031 to 9100 m and shows indications of leakage in the casing at depths 5200–5600 m. Analysis of the pressure record and hydraulic modelling suggest the existence of a weak hydraulic communication between the two boreholes, probably at depths around the leakage. Hydraulic modelling of a major slug‐test in KTB‐HB that was run during the pumping in KTB‐VB reveals the effective transmissivity of the connected formation to be 1 to 2 orders of magnitude lower than the one determined for the SE2 fault zone.     

‘Attaque and Break Through a Phalanx of Corruption . . . the Court Party!’ The Scottish Representative Peers' Election and the Opposition, 1733–5: Three New Division Lists of the House of Lords of 1735*

In the early 1730s, Archibald Campbell, the earl of Ilay, gained a dominant position in Scotland, and Sir Robert Walpole, the prime minister, entrusted him with the distribution of patronage there. Ilay took full advantage of this power, and controlled the votes of the financially weak Scottish peers in the election of 16 representative peers. The excise crisis of 1733–4, however, changed the political scene in Scotland. Although they had been chosen as supporters of the court party, some of the Squadrone Volante members (the duke of Montrose and the marquess of Tweeddale) and two courtiers (the earls of Marchmont and Stair) raised a standard of revolt against Walpole and Ilay. The Scottish opposition co‐operated with the English country party (‘the Patriots’) and such Scottish tories as the duke of Hamilton. In the 1734 peers' election they launched a challenge to the ministry, but the opposition was crushed by a bankrolled election campaign organised by the court party. Although the English and Scottish opposition petitioned in the house of lords to criticize the ‘undue practices’ of Walpole and Ilay at the election, the ministry was backed up by English and Scottish courtiers and bishops, and overwhelmed the opposition. Three new division lists related to the aftermath of the Scottish election shed much light upon the party alignment of the upper House in the middle of the 1730s.     

The Legacy of Isaac Schapera (1905–2003)

'I would like to be remembered – although I am sure that I will not be – as the equivalent, to the Tswana, of what Pepys is to English ethnography.' Isaac Schapera interviewed by Jean and John Comaroff, 1988     

“We Seem to Have Always Spoken in Prose . . .” Policy Analysis Is a Clinical Profession: Implications for Policy Analysis Practice and Instruction

The purpose of this article is (i) to propose the concept of policy analysis as a clinical profession, (ii) to relate to the clinical intellectual processes involved in policy analysis, and (iii) following studies in other clinical disciplines, to infer implications for policy analysis and policy analysis instruction. The article will highlight notions of clinical reasoning and clinical cognitive processes relevant to policy analysis and will address reasoning errors associated with bounded rationality and uncertainty in the clinical analytic process. The article seeks to promote awareness of clinical notions and of their relevance for policy analysis practice and instruction.
