We report an unusual case of a medullary sponge kidney that presented clinically and radiologically as a renal mass. Histopathological study after nephrectomy proved the mass to be consistent with ...segmental medullary sponge kidney.
Parallel metaheuristics based on Multiple Independent Runs (MIR) and cooperative search algorithms are widely used to solve difficult optimization problems in diverse domains. A key step in assessing ...and improving the speed of global convergence of parallel metaheuristics is tracing solutions explored by the MIR-based algorithm. However, this generates large amounts of data, thus posing execution problems. This problem can be resolved by using a flow control workflow to govern the execution of the MIR-based parallel metaheuristics. Using a Spares Management and Optimization case study for the logistics industry, this paper analyzes the performance of the flow control workflow with different problem sizes. We show that by appropriately setting workflow parameters, namely: (1) stop criterion to limit the amount of data cached and exchanged, and (2) clustering policy to distribute/aggregate parallel processes to compute nodes selectively, the performance of the algorithm can be improved.
The nature and severity of drug use has been measured both directly and indirectly by various studies employing different indicators, although the majority of studies still tend to use single ...measures of drug use. The need to employ multiple measures in examining drug abuse is constrained by the fact that available data may have been collected through diverse methodologies and measured on different levels or units. The purpose of this study was to develop and test in Philadelphia a model using qualitatively different types of data integrated by the common geographic unit of a census tract. The types of data used included: archival data, key informant data, and survey data. Using this approach the paper examines the relationships of drug use measures to each other, to the social environment, and to drug market factors. Major findings of the analysis indicate that there are several independent measures of drug use as reflected in five composite indicators which differentiate behavioral activities or consequences of drug use. Moreover, heroin use indicators exhibit relationships with social-environmental characteristics and drug market factors which are different from those existing with amphetamine or synthetic drug use.
The role of field instructors in preparing graduate social workers for autonomous & accountable practice is examined, & suggestions are proposed for the learning process. Characteristics of the ...student-instructor relationship, learning plan or contract, supervisory conferences, & instructor models are discussed. The need for the student's active participation in the learning process, & in assessment & evaluation of field work performance, in preparation for future autonomy is described. 31 References. M.
