IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument. 相似文献
This study provides a glimpse into understanding the potential benefits as well as harm of playing video games from the perspective of six Malaysian secondary school students, aged 16-17 years old. The rationale of the study is to enable parents, educators, administrators and policy makers to develop a sound understanding on the impact of playing video games before making any judgment on the contemporary youth culture. Thus, further decision on the acceptance of video games as a new innovation in school or at home could be considered. Although this study is not very extensive, the findings suggest that playing video games contributes to cognitive, social, motivational and emotional development. However, potential harms do exist. Parents play an important role in guiding their children either directly or indirectly, as indicated by the respective students. Caution is advised in the interpretation of the study＇s findings as it is solely based on the perspectives of the students, as the first person＇s views. Nevertheless, each student has their very own perspective on the impact of video games on them. 相似文献
This study investigated how peer comments made using a video annotation tool (VAT) through an online learning community improved student-teachers’ level of reflective thinking and communication competence throughout the simulated (i.e., role-play) context of consultation practice. Eighty student-teachers from two classes of the course “Comprehensive School Guidance” participated in this study, and all recorded two videos for their tripartite practice on parent consultation for self-evaluation and peer comment. Forty student-teachers were in the comparison class and provided general comments to their peers on the learning platform, while those in the experimental class used the VAT on the learning platform to provide specific comments to their peers. Two post-practice online questionnaires and reflective journal entries, which aimed to measure communication competence and reflective thinking ability, were administered to the student-teachers after the first and second consultation practice. The reflective journal entries were segmented into units of analysis that were scored using a 4-level model of reflective thinking (from 1 to 4), with a higher score indicating demonstration of a higher level of reflective thinking for that particular segment. Both the number of reflective notes made and the average level of reflective thinking in student-teachers’ journal entries were indicators of reflective thinking ability. Two mixed ANOVAs were conducted to examine whether student-teachers in the experimental (VAT) class improved their reflective thinking ability and communication competence more significantly than those in the comparison (non-VAT) class. The results showed that student-teachers in both the VAT and non-VAT classes had statistically higher scores for communication competence and reflective thinking in the second role-play practice. Student-teachers with the support of VAT, in comparison to those without, significantly improved their average reflective thinking ability. Focus group interviews were also conducted to investigate how VAT could support student-teachers’ learning process and to learn their perceptions of the strengths and limitations of the VAT. The results indicated that the VAT could enhance student-teachers’ learning by reducing communication barriers created by the tendency to avoid direct observations of peers’ weaknesses, enhancing reflection-in-action during practice, and contextualizing written comments by referring to specific video segments. However, student-teachers felt that the VAT should also allow users to draw on the video screens.
Taking into account uncertainties in model parameter values is a crucial point for studying robustness in modeling and in control. This paper proposes to construct in a systematic and graphical procedure two forms of the linear state equation usually found in the literature for dealing with the robustness problem in the case of structured uncertainties on parameters. It is shown how to model uncertainties in a bond graph approach, in the case of additive or multiplicative parametric variations. 相似文献
The underlying calculus assumption of Holland’s theory was tested in two samples of primary school students (N1 = 400 and N2 = 250) with an average age of 13.86 and 14.14 years, respectively. Both exploratory and confirmatory multidimensional scaling and Hubert and Arabie’s randomization test of hypothesized order relations were calculated. The circular spatial arrangement of RIASEC types was not confirmed in either of the two samples. The study discusses possible causes of the inappropriateness of using Holland’s model in an adolescent sample.
A key tenet of the Home–School Knowledge Exchange Project is that children's learning will be enhanced if the knowledge and experience that are to be found both at home and in school can be brought together. In this paper we explore ways of connecting home and school to support literacy learning at Key Stage 1, focusing on the home‐to‐school direction. We discuss how shoeboxes, filled with children's artefacts, can support a range of literacy‐related activities in school. It is suggested that the extensive diversity of knowledge and interests reflected in the chosen objects presents teachers with an invaluable opportunity to personalise children's literacy learning. 相似文献
The present study investigated preservice teachers’ self‐efficacy in classroom management involving students with symptoms of Attention Deficit/Hyperactivity Disorder (ADHD). A total of 137 Chinese preservice teachers were randomly presented with one of four vignettes involving a student character with ADHD symptoms, with manipulations including the character’s gender and diagnostic label of ADHD. Upon reading the vignette, participants responded to questions concerning their self‐efficacy in inclusive classroom management involving the character. Findings based on analysis of covariance indicated an interaction effect of the vignette character’s gender and label on teachers’ self‐efficacy. Specifically, teachers perceived greater self‐efficacy in a classroom involving a girl with an ADHD label than in a classroom involving a girl with no label or a boy with a label. Findings enriched the literature concerning the roles of gender and label in preservice teachers’ self‐efficacy toward inclusive classroom management. 相似文献
ABSTRACTAdvocacy is a complex set of applications that applies knowledge of human behavior in the social environment to promote the rights of others. The purpose of this study was to explore the usefulness of student-created public service announcements (PSAs) to help BSW students learn cause-based advocacy. Our results suggest that assigning a PSA project supports competencies in cause-based advocacy, professional identity development social work, critical thinking, engagement with research-informed practice, and capacity to respond to contexts. 相似文献
ABSTRACTIn the past few decades, the internationalisation of higher education has become an increasingly popular trend across different parts of the globe. The fierce global competition and the aggravating unemployment rate, coupled with low teaching and research quality revealed by universities in mainland China, have inevitably compelled a growing number of Chinese students, in particular the financially-able ones, to pursue higher education overseas or to enrol in transnational higher education offered in mainland China. Realising the severe problem of ‘brain drain’ and having a strong conviction to transform its higher education system to become more international for enhancing the global competitiveness of its higher education system, the Chinese government has made different attempts to enhance higher education quality by learning and incorporating new ideas and practices from overseas institutions, particularly encouraging the development of transnational higher education to change the higher education landscape. With particular reference to examining the way these students evaluate their future prospects in choosing different alternatives for further studies in higher education, this study sets out against the context briefly outlined above to critically analyse the motivation of students who choose to study abroad or enrol in Sino-foreign cooperation universities. This study also discusses the extent to which the internationalisation of higher education would affect the situations of ‘brain drain’ and graduate employment in China. 相似文献
