 Study urges caution in contaminant source tracking
When researchers sent E. coli challenge isolates (the sources of which were unknown to those conducting the tests) for testing, many isolates either remained unclassified or were classified to incorrect sources.
Some E. coli strains have been found in more than one animal source, such as when animals live in close proximity with one another, though no evidence to support this premise was found in the USGS study.
For the immediate future, researchers and end users would be prudent to use caution and to incorporate quality-control measures to validate the accuracy of source tracking results.

Limited efforts to track sources of natural bacterial populations have been made; the approaches used were based on quantification of indicator organisms at various sites; however, these studies invariably have raised more questions than answers.
This validated tracking system for identification of sources of microbial pollution can be used to identify and assess the impact and contribution of non point sources of microbial pollution and to establish and characterize the impact of the point sources of microbial pollution in fecal runoff.
The method can be used to identify the sources of fecal coliforms at the species level and map their distribution, transport, and movement in watersheds, rivers, lakes, and drinking-water-distribution systems.

Setting both the Tracking Source and Frequency lets you and your employees plan how often you will document their efforts and give them feedback on how well they're doing.
To track Behavioral Expectations on the Dimensions, however, you will need to plan how to observe your employees' Behavioral Expectations such as "Greets customers promptly and courteously" or "Reviews work carefully for completeness and accuracy." You can monitor trends related to the employee's Behavioral Expectations using the STAR method.
As you select tracking measures, think about how often you will be able to observe or document each expectation, since it may not be possible to directly observe each employee on a daily basis.

 Bacterial Source Tracking (BST)
While great strides have been made to identify levels or concentration of fecal pollution in our waterways, finding the source or cause of that pollution is necessary if the problem is to be corrected.
As humans, domestic animals, and wildlife cohabitate many regions of the country, simply reporting high fecal bacterial counts in a waterway does not indicate whether the source is the result of a leaky septic tank, the adjacent feed lot, or the large deer population.
Activities are currently underway to provide grant and contracted services to federal and state agencies, as well as to private citizens and citizen groups seeking to identify the source of fecal contamination in their region or state.

 Mergere Adds Open Source Tracking to Source Code Management - Computer Business Review   (Site not responding. Last check: )
Mergere Inc, an open source tools firm targeting application lifecycle management, is adding features to its repository to improve the tracking of open source code itself, which is playing a larger role in internal software development projects.
Traditionally, most source code control and change management tools do a pretty good job of tracking who is responsible for which versions of which code if the software in question was developed internally.
Starting a new Apache open source project, Archiva, Mergere is using the technology to provide a form of sandbox where you collect open source artifacts, label them as such, and place flags or alerts like when the development team should check on the status or rights to the code.
