Validation of a laboratory and hospital information system in a medical laboratory accredited according to ISO 15189

Introduction

The aim of the study was to present a protocol for laboratory information system (LIS) and hospital information system (HIS) validation at the Institute of Clinical Chemistry and Laboratory Medicine of the Merkur University Hospital, Zagreb, Croatia.

Materials and methods:

Validity of data traceability was checked by entering all test requests for virtual patient into HIS/LIS and printing corresponding barcoded labels that provided laboratory analyzers with the information on requested tests. The original printouts of the test results from laboratory analyzer(s) were compared with the data obtained from LIS and entered into the provided template. Transfer of data from LIS to HIS was examined by requesting all tests in HIS and creating real data in a finding generated in LIS. Data obtained from LIS and HIS were entered into a corresponding template. The main outcome measure was the accuracy of transfer obtained from laboratory analyzers and results transferred from LIS and HIS expressed as percentage (%).

Results:

The accuracy of data transfer from laboratory analyzers to LIS was 99.5% and of that from LIS to HIS 100%.

Conclusion:

We presented our established validation protocol for laboratory information system and demonstrated that a system meets its intended purpose.     

Dynamic Transition Patterns in Acculturation Among Hispanic Adolescents

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, M_age (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed.     

SOCIAL CLASS AND PERFORMANCE ON AN INTELLIGENCE TEST

Noting the wide differences in verbal abilities of middle and lower class children, the investigators proposed that two groups of children, one from the lower class, one from the middle class, who achieve comparable total scores on a group intelligence test, would get their scores by successfully completing different sets of items. In the first study children were placed in social classes based on their fathers' occupations, following guidelines from the Warner scale. Middle class children were matched with lower class children on total Otis scores. No item-social class interaction was found. The study was repeated using the occupational categories of the Dictionary of Occupational Titles as a guide to social class standing. Again no item-social class interaction appeared. If two social class groups are equated on total intelligence scores, one social class sample appears to succeed on essentially the same test items as does the other social class sample. A given score on an intelligence test appears to represent the same skills for one social class as it does for another social class.     

College attrition,student use of campus facilities,and a consideration of self-reported personal problems

Five groups of undergraduate students, Dropouts (academic dismissals), Low Stopouts (voluntary leavers with low GPA), Low Persisters (continuing students with low GPA), High Stopouts (voluntary leavers with high GPA), High Persisters (continuing students with high GPA), were compared in terms of their use of various campus facilities and their responses to a checklist of personal problems. The High Stopouts and High Persisters did not differ in use of facilities. However, among the low academic performance students, the Low Persisters made significantly greater use of facilities than the Low Stopouts, who, in turn, made significantly greater use of facilities than Dropouts. These findings, for the most part, did not appear to be related to the self-reported importance of personal problems. It was concluded that among low performance students, the broad use of campus services and facilities can be taken as a measure of student integration in the college community.     

A teacher education program in elementary science that connects content,methods, practicum,and student teaching

Conclusion To educate teachers who have adequate content knowledge, possess the necessary skills to implement effective teaching strategies, and are confident and have positive attitudes toward science and the teaching of science, alternative teaching models are necessary. The University of Wyoming model provides such an alternative. Based on observations and interviews of students and the mentor teachers, it is apparent that it has created a very positive response in prospective teachers who have participated in it. The Wyoming model provided an effective process to train future elementary teachers. Even though it focused on science, the basis is general enough that it could be successfully extended to other disciplines with only minor modifications; however, all of the major components of the Wyoming model are vital to its success. Content courses designed specifically for prospective teachers have been successful in giving the students the content knowledge and providing opportunities for effective modeling. The seminars provide strong mechanisms to connect content to methodology and make the content relevant to teaching and to children. Because of their modeling, peer coaching, and sharing their time and students, the mentor teachers are essential partners in helping the university educate future teachers. Finally, the cooperation of all partners—district administrators, teachers, science content and science education university faculty, and students—is necessary to provide early and continuous experiences to prospective teachers.

Computers in Artificial Intelligence Education

Both the origin and development of artificial intelligence (AI) are connected with the origin and development of computers. Computers play a very important role in engineering education. AI influences such disciplines like CAD, CASE, CAE, and others. The specific experience concerning AI education at a technical university has been gathered in this paper. There is stressed need of good balance between theoretical background and individual training with computers as well as importance of personal experience in solving practical AI.     

Observations of Parent Reactions to Sex-Stereotyped Behaviors: Age and Sex Effects

To examine differential socialization of boys and girls by mothers and fathers, home observations were completed for families of 92 12-month-old children, 82 18-month-old children, and 172 5-year-old children. Mothers gave more instructions and directions than did fathers, while fathers spent more time in positive play interaction. Differences in parents' reactions to 12- and 18-month boys and girls were as expected, with the exception that boys received more negative comment for communication attempts than did girls. The suggestion in the literature that fathers would be more involved in sex typing than mothers was not confirmed in this study. The only 2 significant sex-of-parent x sex-of-child effects occurred at 18 months; fathers gave fewer positive reactions to boys engaging in female-typical toy play, and mothers gave more instruction to girls when they attempted to communicate. We argue that the second year of life is the time when children are learning many new skills and when parents are still experimenting with parenting styles and may well use stereotypical responses when unsure of themselves.     

The Adolescent in the Online Game

This article addresses the need for changes in current views on adolescent development. It presents observations of adolescent behavior in the online game Dragon Nest that were conducted by specialists from the Crossroads Center for Social and Psychological Adaptation and Adolescent Development, Moscow State University of Psychology and Education, in 2013. These observations helped form theories about age-specific tasks arising in adolescence. The restorative approach was selected as the theoretical basis for this work. This approach represents the practical application of the cultural-historical theory and the activity theory to the provision of social and psychological assistance to adolescents. An analysis of adolescent activity in a game, the structure of communication, and observations of adolescent relationships in online gaming space make it possible to form theories on the role of communication among peers in today’s society in terms of adolescent individuation and development.     

Special education placement decisions made by teams and individuals: A cross-cultural perspective

The present study looked at whether special education placement decisions made by teams are superior to those made by individuals. The investigation was conducted in Puerto Rico to determine whether the benefits of the cooperative group process exist in another culture. Results indicated that teams in Puerto Rico generated significantly less variability (i.e., errors) in their placement decisions than did the same specialists acting independently.
