Teaching note – was the champions league draw rigged?          下载免费PDF全文

Henk Tijms 《Teaching Statistics》2015,37(3):104-105

This teaching note gives a real‐life example of Bayesian thinking. It discusses how credible accusations are that the outcome of the draw for the quarter‐finals in the 2013 European Champions League Football was manipulated.  相似文献   

Genetic and Environmental Etiologies of the Longitudinal Relations Between Prereading Skills and Reading          下载免费PDF全文

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post‐first grade (M = 7.4 years), and post‐fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print knowledge, rapid naming, phonological awareness, vocabulary, and verbal memory) were primarily responsible for relations with word reading and spelling. However, relations with post‐fourth‐grade reading comprehension were due to both genetic and shared environmental influences. Genetic and shared environmental influences that were common among the prereading variables covaried with reading and spelling, as did genetic influences unique to verbal memory (only post‐fourth‐grade comprehension), print knowledge, and rapid naming.  相似文献

Organisational forms of science communication: the UK and Spanish European higher education systems as paradigms     

Ojeda-Romano  Gabriela  Fernández-Marcial  Viviana  Wilkinson  Clare  Stengler  A. Erik 《Higher Education》2022,84(4):801-825

As key elements in research and development systems, higher education institutions have been taking a leading role when it comes to communicating science and technology, but their performance has been inconsistent so far. In this critical and comparative study of the UK public engagement model and the Spanish scientific culture model, eighteen practitioners from higher education institutions across both regions were interviewed. A mixed qualitative data analysis has been performed identifying similarities and differences that unravelled the science communication management model in the two different higher education systems. This article provides evidence on how the institutionalisation of science communication is strongly influenced by key driving forces in the higher education context as well as the policies of administrations and other agents.

Writing to learn: can reflection journals be used to promote self-reflection and learning?     

Duan Ning Magdeleine Lew  Henk G. Schmidt 《高等教育研究与发展》2011,30(4):519-532

The purpose of the present study was to evaluate whether there is evidence of reflection in student-written journals and to investigate whether students show improvements in their reflective skills through journal keeping. To that end, the reflection journals of 3460 first-year students enrolled in a polytechnic were studied by means of an automated coding procedure. Data used in the analyses were students' journals for an entire week, collected once at the beginning and again at the end of an academic year. Outcomes of the content analyses suggest that there is evidence of reflection in students' journals and that students reflected on three general categories related to their learning: critical review of past learning experiences, cognitive learning strategies and summaries of what was learnt. Furthermore, the findings also indicate that students show improvements in their reflective skills as they progressed through the academic year. The findings when taken together suggest that reflection journals can be used to promote self-reflection and learning amongst students.  相似文献   

Complex three-dimensional high aspect ratio microfluidic network manufactured in combined PerMX dry-resist and SU-8 technology     

Meier RCh  Badilita V  Brunne J  Wallrabe U  Korvink JG 《Biomicrofluidics》2011,5(3):34111-3411110

In this paper we present a new fabrication method that combines for the first time popular SU-8 technology and PerMX dry-photoresist lamination for the manufacturing of high aspect ratio three-dimensional multi-level microfluidic networks. The potential of this approach, which further benefits from wafer-level manufacturing and accurate alignment of fluidic levels, is demonstrated by a highly integrated three-level microfluidic chip. The hereby achieved network complexity, including 24 fluidic vias and 16 crossing points of three individual microchannels on less than 13 mm(2) chip area, is unique for SU-8 based fluidic networks. We further report on excellent process compatibility between SU-8 and PerMX dry-photoresist which results in high interlayer adhesion strength. The tight pressure sealing of a fluidic channel (0.5 MPa for 1 h) is demonstrated for 150 μm narrow SU-8/PerMX bonding interfaces.  相似文献

Measures of international collaboration in scientific literature: Part II     

Abraham Bookstein  Henk Moed  Moshe Yitzahki 《Information processing & management》2006,42(6):1422

This paper continues the attempt of Part I to develop a coherent family of measures of influence between classes of documents, for example, language or nationality classes, as indicated by citation choice. In this paper we focus on situations in which there is some ambiguity as to how to assign items to a class. For simplicity, we change our focus from citations to co-authorship patterns, restricting most of our discussion to papers with two authors. Like the earlier paper, we propose very simple models of the citation decision, and base our measures on the parameters that appear in the model.  相似文献   

Szenario-basierter Systemtest von Software-Produktfamilien     

Andreas Reuys  Erik Kamsties  Klaus Pohl und Sacha Reis 《Informatik - Forschung und Entwicklung》2005,20(1-2):33-44

Zusammenfassung In der Produktfamilienentwicklung werden durch zwei Entwicklungsprozesse, Domain und Application Engineering, zun"achst wiederverwendbare Entwicklungsartefakte produziert, um diese anschlie?end zur Konstruktion von kundenspezifischen Applikationen einzusetzen. Die Wiederverwendbarkeit wird durch die explizite Definition der Variabilit"at der geplanten Applikationen einer Produktfamilie erzielt. Diese proaktive Wiederverwendung ist bisher in den konstruktiven Entwicklungsphasen realisiert, jedoch noch nicht im Test. Mit ScenTED (Scen_ario based TE_st Case D_erivation) wird in diesem Beitrag eine wiederverwendungsorientierte Technik zur Testfallerstellung f"ur den Systemtest, dem Test eines ausf"uhrbaren Systems gegen spezifizierte Use-Cases, von Produktfamilien vorgestellt. ScenTED basiert auf zwei Kernideen: der Erhaltung der Variabilit"at in Testf"allen und der Szenario-basierten Verfeinerung der Testf"alle. Durch die Erhaltung der Variabilit"at wird die Wiederverwendbarkeit von Testf"allen gesichert; die Szenario-basierte Verfeinerung erm"oglicht Nachvollziehbarkeit durch die durchg"angige Nutzung von Szenarien. In diesem Beitrag wird die ScenTED-Technik an einem Beispiel erl"autert und Erfahrungen aus dem industriellen Einsatz diskutiert.

Product family engineering consists of two development processes: Domain engineering and application engineering. Reuseable artefacts are created in the domain engineering process. These artefacts are used for the creation of customer specific applications during the application engineering process. Reusability is achieved with the explicit definition of variability that specifies the potential applications of the product family. The proactive reuse has been realized in the construnction phases of the development process, but not within the test phases. We propose ScenTED (Scen_ario based TE_st Case D_erivation) for the creation of reusable test cases for a use case based system testing in product family engineering. ScenTED has two key ideas: The first is the preservation of variability in test cases and the second idea is the scenario-based refinement of test cases. The preservation of variability ensures the reusability of test cases. The scenario-based refinement enables the traceability from requirements to test cases. We present the ScenTED technique in this article with an example and discuss an industrial case study.
