XML conceptual modeling with XUML

HongXing Liu, YanSheng Lu, Qing Yang
2006 Proceeding of the 28th international conference on Software engineering - ICSE '06  
In order to design or integrate XML schemas, it is necessary to first design the conceptual structures with a proper conceptual model.  ...  Based on XUML, we further present a framework of the methodology which is dedicated to the design of XML documents and XML databases. In this paper, the focus is put on XUML.  ...  Firstly, we are specifying the XUML meta-model formally; secondly, we are planning to implement a XUML-based CASE tools; lastly, we will further develop and evaluate the XUML-Based methodology.  ...

On the Relationship Between Classical Test Theory and Item Response Theory

Tenko Raykov, George A. Marcoulides
2015 Educational and Psychological Measurement  
The frequently neglected and often misunderstood relationship between classical test theory and item response theory is discussed for the unidimensional case with binary measures and no guessing.  ...  Keywords binary item, classical test theory, item response theory, observational equivalence, unidimensionality For much of the past century, classical test theory (CTT) was the dominant framework for  ...  These relationships can be seen as closely tied to those between factor analysis (FA) and IRT, which have been pointed out in the methodological literature over the past 30 years or so (e.g., Kamata &  ...

Fully informed? A methodology for assessing covert informant coverage in policing and law enforcement

Colin Atkinson
2019 The Police Journal  
The future testing of such a methodology in practice will represent a critical area for further development and debate.  ...  Drawing upon social penetration theory, this article proposes a new methodology to support police and law enforcement agencies in systematically mapping the breadth and depth of informant coverage.  ...  To arrive at this advanced methodology, it is first necessary to sketch a basic analysis of informant coverage, a 'binary approach', and an account of how such methodologies can be integrated into routine  ...
