You may enclose your SIG membership renewal with your ballot without fear of compromising its secrecy.

For SIG Chair

Nikolaus Bezruczko
"A MESA graduate, my professional specialization is social measurement and evaluation consulting. In particular, ability and aptitude test development to assess visual arts and social competence. Over the past 20 years, I have extended this expertise into longitudinal data base analyses. Through experiences with foundations, universities, and government, I have found social research ideologically divided and uncommitted to scientific advances. Antiquated methods are frequently unrelated to scientific logic. Unless we incite reform, increasing fragmentation and incoherence of the social sciences will embarrass and discredit us all. If elected Rasch SIG chair, I will pursue opportunities to express the strong links between Rasch methods and scientific thinking emphasizing their necessity for social research survival. I believe by making our links with scientific tradition explicit, not only do we model effective scientific practices for our peers but provide them with a coherent social research vision."
Nikolaus Bezruczko, Ph.D.,

Mary Lunz
"I specialize in the multi-facet analysis of performance examinations. I have worked in Rasch measurement for 15 years, publishing many papers on oral examination analysis and computerized adaptive testing. Currently, I serve as Secretary/Treasurer of the Institute for Objective Measurement. My goal is to encourage the expansion of the use of the Rasch model for analysis of education and social science applications"
Mary E. Lunz, Ph.D,

For Secretary

George Karabatsos
As an Assistant Professor at the Louisiana SU Health Sciences Center, my research interests involve developing the mathematical and philosophical foundations necessary to construct practical, objective measurement in the health and social sciences (conjoint additivity, inferential stability). This includes the design, application, teaching, and publication of better methods for measuring and verifying the quality of variables in medical education, health care, and psychology. I have a special interest in analyzing the current methods, and developing new methods, for detecting measurement disturbances in Rasch analysis (i.e., aberrant person responses, item multidimensionality). My current projects at the LSUHSC include the development of an evaluation system designed to measure medical students' patient communication skills within simulated medical scenarios; the development of mathematical models to measure the diagnostic decision processes of medical students within the context of computerized medical scenarios simulating patient illnesses; the construction of computer- assisted learning and testing at the LSU Health Sciences Center; the demonstration and implementation of fundamental measurement principles to health care services research.
George Karabatsos, Ph.D.,

Tom O'Neill
"I am the Psychometrician for the American Dental Association. I have worked for health-related certification boards and associations for the last ten years. My professional interests include performance assessment, computer adaptive testing, and issues related to cheating. In my view, the most important contribution that measurement professionals can do for the fields that they support is to help them to create stable and clearly understood constructs. Rasch measurement will excel in this arena over the next 15 to 20 years."
