BACKGROUND Physician migration from poor to rich countries is considered an important contributor to the growing health workforce crisis in the developing world. This is particularly true for Africa. The perceived magnitude of such migration for each source country might, however, depend on the choice of metrics used in the analysis. This study examined the influence of choice of migration metr...

This paper investigates the relation between the level of detail (LoD) in UML models and defect density of the associated implementation. We propose LoD measures that are applicable to both classand sequence diagrams. Based on empirical data from an industrial software project we have found that classes with higher LoD, calculated using sequence diagram LoD metrics, correlates with lower defect...

Measuring complexity of business process models is a rather new area of research. Since there are only a few contributions, it is not yet clear which metrics are needed in order to guide and increase the quality of model design. In this paper, we propose a density metric inspired by social network analysis in order to quantify the complexity of an EPC business process model on a scale between z...

there have been different indices identified for desertification. among these is technogenic desertification index which seems much more efficient. in this study, some of technogenic desertification indices were studied and evaluated. first land use maps of the region were taken from irs-pan satellite image and aerial photos analysis. after evaluating the area of different uses, lands that had ...

Wind resource in the continental and offshore United States has been reconstructed and characterized using metrics that describe, apart from abundance, its availability, persistence and intermittency. The Modern Era Retrospective-Analysis for Research and Applications (MERRA) boundary layer flux data has been used to construct wind profile at 50 m, 80 m, 100 m, 120 m turbine hub heights. The wi...

Traditionally, monitoring solutions are based on collecting a reduced set of external metrics about the system such as performance, memory consumption or response time. However, these tools are limited to detecting and diagnosing failures or errors in complex systems like application servers and grid services. New applications have embedded monitoring logic merged with business logic to better ...

Theories of word recognition agree that multiple word candidates are activated and compete for recognition when a word is read or heard. Orthographic and phonological density metrics have provided significant, but partial, accounts of this activation and competition process. We extend this approach to examine the impact of semantic neighborhood density on visual semantic access. We compare meas...

Cohesion and coupling metrics at package and subsystem level play a crucial role in guiding software packaging (partitioning) and analyzing the maintainability and reusability of software. There has been a number of attempts to propose frameworks to assess the cohesion and coupling metrics at class level. A little work has been done at a higher level. In this paper, we survey the existing cohes...
