PC_Eyewitness and the sequential superiority effect: computer-based lineup administration.

Computer technology has become an increasingly important tool for conducting eyewitness identifications. In the area of lineup identifications, computerized administration offers several advantages for researchers and law enforcement. PC_Eyewitness is designed specifically to administer lineups. To assess this new lineup technology, two studies were conducted in order to replicate the results of previous studies comparing simultaneous and sequential lineups. One hundred twenty university students participated in each experiment. Experiment 1 used traditional paper-and-pencil lineup administration methods to compare simultaneous to sequential lineups. Experiment 2 used PC_Eyewitness to administer simultaneous and sequential lineups. The results of these studies were compared to the meta-analytic results reported by N. Steblay, J. Dysart, S. Fulero, and R. C. L. Lindsay (2001). No differences were found between paper-and-pencil and PC_Eyewitness lineup administration methods. The core findings of the N. Steblay et al. (2001) meta-analysis were replicated by both administration procedures. These results show that computerized lineup administration using PC_Eyewitness is an effective means for gathering eyewitness identification data.

PC_Eyewitness: a computerized framework for the administration and practical application of research in eyewitness psychology.

Eyewitness identification evidence is an important aspect of our legal system. Society relies on witnesses to identify suspects whom they have observed during the commission of a crime. Because a witness has only a mental representation of the individual he or she observed, law enforcement must rely on verbal descriptions and identification procedures to document eyewitness evidence. The present article introduces and details a computer program, referred to as PC_Eyewitness (PCE), which can be used in laboratories to conduct research on eyewitness memory. PCE is a modular program written in Visual Basic 6.0 that allows a researcher to present stimuli to a participant, to conduct distractor tasks, to elicit verbal descriptors regarding a target individual, and to present a lineup for the participant to provide an identification response. To illustrate the versatility of the program, several classic studies in the eyewitness literature are recreated in the context of PCE. The program is also shown to have applications in the conduct of field research and for use by law enforcement to administer lineups in everyday practice. PCE is distributed at no cost.

Development of a rubella vaccination strategy: contribution of a rubella susceptibility study of women of childbearing age in Kyrgyzstan, 2001.

To contribute to the development of a rubella vaccination strategy, we conducted a study to determine age-specific susceptibility among women aged 15-39 years by testing for rubella-specific IgG antibodies. Of 964 women, 13% were found to be susceptible to rubella. Significantly higher susceptibility among women >25 years old was observed. Susceptibility data are important but are not sufficient to develop a vaccination strategy. After considering all available information, we suggested vaccination of women aged <35 years and selective vaccination of older women who were planning pregnancy.

Immunization information systems national research and evaluation agenda.

Immunization Information Systems (IIS) are operational in most states and are useful in programmatic and clinical assessments. To ensure that IIS reach their technical and usability potential, and to promote their use, we conducted a Delphi survey to develop a national IIS research and evaluation agenda. Experts with a wide range of IIS knowledge were asked to generate research and evaluation topics that document their utility in achieving and sustaining clinical and public health goals. Topics were then collated by the authors into 13 main categories and were ranked by the survey experts in order of importance. Provider perspectives and needs was ranked as the top research priority. Both data quality and technical data exchange also ranked high, as well as increasing provider participation and IIS cost and cost savings. Lower-ranked research priorities included data sharing between states and factors affecting IIS population-based measurements. Development of an IIS research and evaluation agenda allows policy makers to ensure that their decisions coincide with expert views on national priorities and enables researchers to conduct studies addressing topics recognized as nationally important. It also allows for targeted funding decisions.
