Peacebuilding at the Local Level: Refugee Return to Prijedor'

During the 1992-95 war, Prijedor was synonymous with mass killing, ethnic cleansing and detention camps. A decade after the end of the war, international agencies consider this town to be an example of successful foreign intervention. Thousands of Muslim displaced persons (DPs) returned to their pre-war homes, mosques have been rebuilt, and hard-line Serb nationalists have lost much influence. How could Prijedor turn from a hopeless case of ethnic violence to an example of successful intervention? This essay argues that Prijedor's (relative) success is due more to the determination of Muslim DPs than to the international peacebuilding strategy. The initial post-Dayton international intervention exacerbated the problem of internal displacement, raised ethnic tensions and left Prijedor in the hands of the same indicted war criminals responsible for the war. Against the advice of international agencies, which feared a backlash among the Bosnian Serbs, in 1998 Muslim DPs began returning home. Eventually, large-scale return improved ethnic relations and helped marginalize Bosnian Serb extremists. The essay concludes by highlighting the lessons from Prijedor, and identifies the domestic and international contribution to Prijedor's post-settlement success.

A precisely-dated lake-level rise marked by diatomite formation in northeastern Ireland

The intercorrelation of palaeoclimate events from various studies is often hindered by a lack of precise chronological control. Tephra isochrons can overcome this problem by providing direct site linkages. This paper outlines a study of Holocene peat and diatomite deposits that accumulated within the floodplain of Lough Neagh, Northern Ireland. The Icelandic Hekla 4 tephra has been identified at the base of diatomite deposits at a number of sites and provides firm dating evidence for a widespread flooding event in the area at ca. 2300 BC. The evidence is consistent with other studies in Ireland and elsewhere for increased wetness at this time. The results demonstrate that the terrestrial deposits around Lough Neagh contain an important record of Holocene lake-level change. Dendrochronological evidence from the Lough Neagh area provides additional information about lake-level fluctuations over the past two millennia.

Fully differential cross sections for transfer ionization - a sensitive probe of high level correlation effects in atoms

The transfer ionization process offers a unique opportunity to study radial and angular electron correlations in the helium atom. We report calculations for the multiple differential cross sections of the transfer ionization process p + He --> H + He++ + e(-). The results of these calculations demonstrate the strong sensitivity of the fully differential cross sections to fine details of electron correlation in the target atom. Specifically, angular electron correlation in the ground state of helium results in a broad peak in the electron emission spectra in the backward direction, relative to the incoming beam. Our model explains some of the key effects observed in measurements of multiple differential cross sections using the COLTRIMS technique.

Excitation rate coefficients for transitions from the ground level of Gd XXXVII

Excitation rate coefficients, for transitions from the ground level to excited levels of Gd XXXVII, have been calculated over the temperature range 5002500 eV using the R-matrix method. It is observed that the contribution of resonances enhances the rates by up to an order of magnitude over the available (non- resonant) results of Hagelstein.
