The concurrence of the current postanalytical phase management with the national recommendations: a survey of the Working Group for Postanalytics of the Croatian Society of Medical Biochemistry and Laboratory Medicine

IntroductionThe detection and prevention of errors in the postanalytical phase can be done through the harmonization and standardization of constituent parts of this phase of laboratory work. The aim was to investigate how well the ongoing management of the postanalytical phase corresponds to the document “Post-analytical laboratory work: national recommendations” in Croatian medical biochemistry laboratories (MBLs).Materials and methodsAll 195 MBLs participating in the national external quality assessment scheme, were invited to undertake a part in a survey. Through 23 questions the participants were asked about management of the reference intervals (RI), delta check, reflex/reflective testing, postanalytical quality indicators and other parts of the postanalytical phase recommended in the national recommendations. The results are presented in numbers and percentages.ResultsOut of 195 MBLs, 119 participated in the survey, giving a response rate of 61%. Not all of the respondents provided answers to all the questions. Delta check has not been used in 59% (70/118) of the laboratories. Only 22/113 (20%) laboratories use reflex and/or reflective testing. In 53% of the laboratories, critical results were reported within 30 minutes of the confirmation of the results. In 34% (40/118) of the laboratories, turnaround time and reporting of critical results are two most often monitored postanalytical quality indicators.ConclusionThe results showed the critical results reporting and monitoring of postanalytical quality indicators are in the line with the recommendations. However, the management of RI verification, the use of delta check and reflex/reflective testing still must be harmonized among Croatian MBLs.

Vectors of identity development during the first year: black first-generation students’ reflections

In this study, black South African first-generation students’ experiences related to identity development during their first year at a higher education institution were explored. Chickering and Reisser’s [1993. Education and Identity. 2nd ed. San Francisco, CA: Jossey-Bass] seven-vector identity development theory served as overarching framework. The focus group discussions and individual interviews of ten black first-generation students were analysed thematically. Participants experienced their first year as a time of instability, mostly due to inadequate preparation for the psychological, social, and especially academic challenges of higher education. Black first-generation students’ ability to remain connected to their family while forming new social connections on campus enabled them to feel safe in their exploration of new worldviews, relationships, and occupational considerations. Black first-generation students’ unique progression in vector attainment confirms the importance of research on the application of Chickering’s theory in a more diverse higher education environment.     

An exploration of the feature-positive effect in adult humans

Experiment 1 compared the acquisition of a feature-positive and a feature-negative discrimination in humans. In the former, an outcome was signaled by two stimuli together, but not by one of these stimuli alone. In the latter, the outcome was signaled by one stimulus alone, but not by two stimuli together. Using a within-group design, the experiment revealed that the feature-positive discrimination was acquired more readily than the feature-negative discrimination. Experiment 2 tested an explanation for these results, based on the Rescorla-Wagner theory, by examining how novel discriminations, based on a combination of a feature-positive and a feature-negative discrimination, were solved. The results did not accord with predictions from the theory. Alternative explanations for the results are considered.     

Mathematics and Science Performance of Primary School Students in the Netherlands

In this contribution the results of Dutch students of grades 3 and 4 in primary education on the TIMSS mathematics and science test are discussed. Despite severe criticism from subject matter experts on the test, the Netherlands score very high in the international ranking list. The nature of the criticism and the features of Dutch mathematics and science education are described to serve as a background for interpreting these surprising results.
