Partnership Networks for Urban Development: How Structure is Shaped by Risk

In delivering public policy, governments worldwide increasingly partner with diverse sets of stakeholders. This spreads commercial risk, but particularly where agendas diverge, introduces new risks related to trust in relationships. The “risk hypothesis” distinguishes between networks for “cooperation” problems, where partners have high individual payoffs for uncooperative behaviors, and “coordination” problems, where partners subscribe to a common goal and uncooperative behaviors are less rewarding. We used mixed‐methods to study networks of local and state government, developers, and consultants that center on joint‐venture partnerships for developing new urban, residential projects. Statistical network methods showed that within the mix of partners involved in development projects, only state governments displayed structural patterns associated with solving “cooperation” problems (rather than coordination). In other words, the patterns of state government interactions showed they are most exposed to risky relationships. In contrast to the state governments’ apparent exposure to risk, qualitative data showed they are not only well trusted but also overall the partnership networks reported very low levels of conflict. By exploring the distribution of “cooperation” and “coordination,” we identified which stakeholders perceived most risk. In our case, how the state governments’ structure interactions in response to risky relationships leads to an overall network characterized by trust.     

The Arab Peace Initiative: Now or Never

It has been almost a year now since President Obama set out for Cairo to deliver what has been seen as one of the largest overtures by the United States to publicly engage the Middle East. Unfortunately, despite the high hopes that this new administration garnered and the continuous efforts of high‐level American officials to put an end to the Arab–Israeli conflict, there is little fruit to bear on the ground. More often than not, the diplomatic breaches and hurdles to even get to the negotiating table have consumed the headlines, and 1 year later the multilateral relations in the region seem tepid at best. The repeated failures of the bilateral negotiations between Israel and the Palestinians and Israel and Syria may be attributed to a number of factors, including a deep‐seated mistrust that has not been addressed, concerns over the long‐term security, and domestic political constraints to make the required concessions to reach an agreement. Yet while all of these elements contributed to the despondent current state of affairs, the one critical missing ingredient has been the absence of a comprehensive framework for peace representing the collective will of the Arab states. Now more than ever, the Arab Peace Initiative (API) offers the best possible chance of achieving an inclusive peace, provided that all parties to the conflict understand its significance and historic implications that have eluded all parties for more than six decades. The likelihood that the current lull in violence will continue if no progress is made on the political front is slim. If the Arab states want to show a united front, especially as the Iranian nuclear advances threaten the regional balance of power, they must finally and publically resolve to promote the API in earnest.     

Metamorphic and basin fluids in quartz–carbonate–sulphide veins in the SW Scottish Highlands: a stable isotope and fluid inclusion study

Metalliferous (Fe–Cu–Pb–Zn) quartz–carbonate–sulphide veins cut greenschist to epidote–amphibolite facies metamorphic rocks of the Dalradian, SW Scottish Highlands, with NE–SW to NW–SE trends, approximately parallel or perpendicular to regional structures. Early quartz was followed by pyrite, chalcopyrite, sphalerite, galena, barite, late dolomite–ankerite and clays. Both quartz–sulphide and carbonate vein mineralisation is associated with brecciation, indicating rapid release of fluid overpressure and hydraulic fracturing. Two distinct mineralising fluids were identified from fluid inclusion and stable isotope studies. High temperature (>350°C) quartz‐precipitating fluids were moderately saline (4.0–12.7 wt.% NaCl equivalent) with low (approximately 0.05). Quartz δ¹⁸O (+11.7 to +16.5‰) and sulphide δ³⁴S (?13.6 to ?1.1‰) indicate isotopic equilibrium with host metasediments (rock buffering) and a local metasedimentary source of sulphur. Later, low‐temperature (T_H = 120–200°C) fluids, probably associated with secondary carbonate, barite and clay formation, were also moderately saline (3.8–9.1 wt.% NaCl equivalent), but were strongly enriched in ¹⁸O relative to host Dalradian lithologies, as indicated by secondary dolomite–ankerite (δ¹⁸O = +17.0 to +29.0‰, δ¹³C = ?1.0 to ?3.0‰). Compositions of carbonate–forming fluids were externally buffered. The veins record the fluid–rock interaction history of metamorphic host rocks during cooling, uplift and later extension. Early vein quartz precipitated under retrograde greenschist facies conditions from fluids probably derived by syn‐metamorphic dehydration of deeper, higher‐grade rocks during uplift and cooling of the Caledonian metamorphic complex. Veins are similar to those of mesothermal veins in younger Phanerozoic metamorphic belts, but are rare in the Scottish Dalradian. Early quartz veins were reactivated by deep penetration of low‐temperature basin fluids that precipitated carbonate and clays in veins and adjacent Dalradian metasediments throughout the SW Highlands, probably in the Permo‐Carboniferous. This event is consistent with paragenetically ambiguous barite with δ³⁴S characteristic of late Palaeozoic basinal brines.
