Privatization in Bosnia and Herzegovina: Insights from and into the craft of interorganizational process analysis.

International efforts to help Bosnia and Herzegovina privatize its state-owned enterprises proved dif.cult, but the complex web of interorganizational relationships (IORs) among international donors, implementers, contractors, and local players, at times, seemed even more daunting to effective implementation of reforms than the technical dif.culties of the task itself. By employing a theoretical framework of IOR development over time, important stages in the evolution of the International Advisory Group on Privatization were identi.ed, and variables within each discussed. Analysis employed linear and nonlinear process logics to help explain what linked some variables withinand betweenthese various phases. Insights seemed valuable for practitioners seeking to implement interdependent tasks, organizational representatives trying to form relationships with others, and scholars trying to understand process theories of IOR formation. In addition, this research provides an introduction to the complexities of international development assistance — a crucially important and under-researched arena.

OPTIMIZING A SHORT-END ELECTROPHORETICALLY MEDIATED MICRO-ANALYSIS (EMMA) ASSAY FOR CREATININE

In this work electrophoretically mediated micro-analysis (EMMA) is used in conjunction with short end injection to improve the in-capillary Jaffé assay for creatinine. Key advances over prior work include (i) using simulation to ensure intimate overlap of reagent plugs, (ii) using OH- to drive the reaction, (iii) using short-end injection to minimize analysis time and in-line product degradation. The potential-driven overlapping time with the EMMA approach, as well as the borate buffer background electrolyte (BGE) concentration and pH are optimized with the short end approach. The best conditions for short-end analyses would not have been predicted by the prior long end work, owing to a complex interplay of separation time and product degradation rates. Raw peak areas and flow-adjusted peak areas for the Jaffé reaction product (at 505 nm) are used to assess the sensitivity of the short-end EMMA approach. Optimal overlap conditions depend heavily on local conductivity differences within the reagent zone(s), as these differences cause dramatic voltage field differences, which effect reagent overlap dynamics. Simul 5.0, a dynamic simulation program for capillary electrophoresis (CE) systems, is used to understand the ionic boundaries and profiles that give rise to the experimentally obtained data for EMMA analysis. Overall, fast migration of hydroxide ions from the picrate zone makes difficult reagent overlap. In addition, the challenges associated with the simultaneous overlapping of three reagent zones are considered, and experimental results validate the predictions made by the simulation. With one set of “optimized” conditions including OH- (253 mM) as the third reagent zone the response was linear with creatinine concentration (R2 = 0.998) and reproducible over the clinically relevant range (0.08 to 0.1 mM) of standard creatinine concentrations. An LOD (S/N = 3) of 0.02 mM and LOQ (S/N=10) of 0.08 mM were determined. A significant improvement (43%) in assay sensitivity was obtained compared to prior work that considered only two reagents in the overlap.
