Revival of test bias research in preemployment testing.

We developed a new analytic proof and conducted Monte Carlo simulations to assess the effects of methodological and statistical artifacts on the relative accuracy of intercept- and slope-based test bias assessment. The main simulation design included 3,185,000 unique combinations of a wide range of values for true intercept- and slope-based test bias, total sample size, proportion of minority group sample size to total sample size, predictor (i.e., preemployment test scores) and criterion (i.e., job performance) reliability, predictor range restriction, correlation between predictor scores and the dummy-coded grouping variable (e.g., ethnicity), and mean difference between predictor scores across groups. Results based on 15 billion 925 million individual samples of scores and more than 8 trillion 662 million individual scores raise questions about the established conclusion that test bias in preemployment testing is nonexistent and, if it exists, it only occurs regarding intercept-based differences that favor minority group members. Because of the prominence of test fairness in the popular media, legislation, and litigation, our results point to the need to revive test bias research in preemployment testing.

Fire Company Staffing Requirements: An Analytic Approach

Fire Company staffing is an important issue. Properly done it ensures sufficiency of hands to perform a variety of tasks required for success on the fire ground. Directly or indirectly staffing affects losses and outcomes and is likely an element in firefighter and civilian safety. While the issue continues as part of a political consensus process, no recent attempts have been documented that suggest a process for local agencies to determine the appropriate company size based on their level of risk assessment and acceptability. This approach provides the practitioner with a model to utilize when considering this issue. It avoids the one-size-fits-all question by demonstrating a methodology for using community demands to determine appropriate fire unit sizing. The resulting process is relatively easily done once the community demands and expectations are identified. The article also considers additional factors other than staffing that can affect the outcome of community testing and that might support or raise questions regarding reliability and validity of the processes.

Moving or Merging IT Departments? The Hardware and Software are the Easy Parts

Although the technical complications in moving or merging a data or telecom department are considerable, it is the human considerations that are most important and critical to the success of the change. This article shows several methods for handling these issues, with real world examples, in order to prevent problems with the change.Eric Klein has an MS degree in information systems and a BBA degree in management information systems, both from Pace University, New York, USA. He has taught classes at both the undergraduate and graduate level at Pace University in New York, USA, the Academic College of Tel Aviv-Yaffo, Israel, and Polytechnic University, Israel in Practical Networking.His practical experience in management consulting is from his experiences at Moran Stahl & Boyer in New York, and as a Senior Technical Consultant for MCI.

Estimating the effect of dialysis staffing ratio regulations on mortality and hospitalizations for Medicare hemodialysis patients

Background and Objectives

Eight states and Washington, DC have implemented regulations mandating a minimum ratio between treatment staff and patients receiving hemodialysis in a facility in an effort to improve the quality of hemodialysis treatment. Our investigation examines the association between minimum staffing regulations and patient mortality for four states and hospitalizations for two states that implemented these rules during our sample period.

Design, Setting, Participants, and Measurements

We utilized a synthetic difference in differences estimation to analyze the effect of minimum staffing ratios on hemodialysis treatment quality, measured by deaths and hospitalizations for end-stage renal disease patients. We used data gathered by the US Renal Data System and aggregated at the state level.

Results

We are unable to find evidence that mandated dialysis staffing ratios area associated with a reduction in mortality or hospitalizations. We estimate a slight reduction in deaths per 1000 patient hours and a slight increase in hospitalizations, but neither are statistically significant.

Conclusions

We were unable to find evidence that minimum staffing ratios for hemodialysis facilities are associated with improved patient outcomes. Our findings highlight the need for future work, studying the impact of these regulations at the facility level.
