Reconciliation and research in Afghanistan: an analytical narrative

This article examines the evolution of western policy towards the idea of pursuing negotiations with the Taliban, or ‘reconciliation’, in Afghanistan and the role that research and expert opinion played in that process. The official western position has evolved iteratively from initial rejection to near complete embrace of exploring the potential for talks. It is widely assumed that the deteriorating security situation was the sole determinant of this major policy reversal, persuading decision‐makers to rethink what had once been deemed unthinkable. Moreover, given the politicized and sensitive nature of the subject, we might expect the potential for outside opinion to influence decision‐makers to be low. Nevertheless, this article demonstrates that it would be a mistake to underestimate the role that research and expert knowledge played—the story is more nuanced and complex. Research coalesced, sometimes prominently, with other key drivers to spur and shape policy change. Importantly, it often took experts to make sense of events on the ground, especially where the failure of the military approach was not recognized, understood or palatable to those in official circles. Research interacted with changing events, policy windows, the emergence of new personalities and the actions of various intermediaries to shape emerging positions. More broadly, the case of reconciliation in Afghanistan reveals the difficulties and challenges, but also the variety of opportunities and techniques, for achieving research influence in conflict‐affected environments.     

Mead-Halls of the Oiscingas: A New Kentish Perspective on the Anglo-Saxon Great Hall Complex Phenomenon

THE GREAT HALL complex represents one of the most distinctive and evocative expressions of the Anglo-Saxon settlement record, and is widely cited as a metaphor for the emergence of kingship in early medieval England. Yet interpretation of these sites remains underdeveloped and heavily weighted towards the excavated findings from the well-known site of Yeavering in Northumberland. Inspired by the results of recent excavations at Lyminge, Kent, this paper undertakes a detailed comparative interrogation of three great hall complexes in Kent, and exploits this new regional perspective to advance our understanding of the agency and embodied meanings of these settlements as ‘theatres of power’. Explored through the thematic prisms of place, social memory and monumental hybridity, this examination leads to a new appreciation of the involvement of great hall sites in the genealogical strategies of 7th-century royal dynasties and a fresh perspective on how this remarkable, yet short-lived, monumental idiom was adapted to harness the symbolic capital of Romanitas.     

Contesting Commerce: Gibbons v. Ogden, Steam Power, and Social Change

The U.S. Supreme Court case Gibbons v. Ogden (1824) ¹ represents one of the most significant yet least understood cases in the history of American jurisprudence. Most accounts depict the case as a constitutional showdown between former New Jersey Governor Aaron Ogden and his estranged business partner, a Georgian businessman and planter named Thomas Gibbons. Ogden charged Gibbons with operating a steamboat on the Hudson River in violation of the Fulton–Livingston Steamboat monopoly that controlled steam travel in the state of New York. In March 1824, Chief Justice John Marshall ruled for the Supreme Court that Gibbons' federal coasting license trumped a state grant issued to Ogden by the Fulton–Livingston syndicate. ²     

Mobilization of ore fluids during Alpine metamorphism: evidence from hydrothermal veins in the Variscan basement of Western Carpathians,Slovakia

Hydrothermal polymetallic veins of the Gemeric unit of the Western Carpathians are oriented coherently with the foliation of their low‐grade Variscan basement host. Early siderite precipitated from homogeneous NaCl‐KCl‐CaCl₂‐H₂O brines with minor CO₂, while immiscible gas–brine mixtures are indicative of the superimposed barite, quartz–tourmaline and quartz–sulphide stages. The high‐salinity aqueous fluid (18–35 wt%) found in all mineralization stages corresponds to formation water modified by interaction with crystalline basement rocks at temperatures between 140 and 300°C. High brominity (around 1000 ppm in average) resulted from evaporation and anhydrite precipitation in a Permo‐Triassic marine basin, and from secondary enrichment by dissolution of organic matter in the marine sediments at diagenetic temperatures. Sulphate depletion reflects thermogenic reduction during infiltration of the formation waters into the Variscan crystalline basement. Crystallization temperatures of the siderite fill (140–300°C) and oxygen isotope ratios of the parental fluids (4–10‰) increase towards the centre of the Gemeric cleavage fan, probably as a consequence of decreasing water/rock ratios in rock‐buffered hydrothermal systems operating during the initial stages of vein evolution. In contrast, buoyant gas–water mixtures, variable salinities and strongly fluctuating P–T parameters in the successive mineralization stages reflect transition from a closed to an open hydrothermal system and mixing of fluids from various sources. Depths of burial were 6–14 km (1.7–4.4 kbar, in a predominantly lithostatic fluid regime) during the siderite and barite sub‐stages of the north‐Gemeric veins, and up to 16 km (1.6–4.5 kbar, in a hydrostatic to lithostatic fluid regime) in the quartz–tourmaline stage of the south‐Gemeric veins. The fluid pressure decreased down to approximately 0.6 kbar during crystallization of sulphides. U‐Pb‐Th, ⁴⁰Ar/³⁹Ar and K/Ar geochronology applied to hydrothermal muscovite–phengite and monazite, as well as cleavage phyllosilicates in the adjacent basement rocks and deformed Permian conglomerates corroborated the opening of hydrothermal veins during Lower Cretaceous thrusting and their rejuvenation during Late Cretaceous sinistral transpressive shearing and extension.
