The purpose of this paper was to analyze the structure of difficult concepts learning within the classroom. The sample of the study was 18 fourth grade students in Central Taiwan, and the exam tools were produced by teachers for math exams. In this paper, a combination of the Rasch Model GSP chart analysis theory, the misconception domain, the Interpretive Structural Modeling (ISM) and Grey Str...

Rhythmic patterns are an important structural element in music. This paper investigates the use of rhythmic pattern modeling to infer metrical structure in musical audio recordings. We present a Hidden Markov Model (HMM) based system that simultaneously extracts beats, downbeats, tempo, meter, and rhythmic patterns. Our model builds upon the basic structure proposed by Whiteley et. al [20], whi...

agricultural sustainability refers to the ability of a farm to produce food indefinitely, without causing irreversible damage to ecosystem health. the main objective of this study was to formulate a structural model to analyze the effects of ecological, social, and economic factors on sustainable agricultural development in qazvin province of iran. to achieve this aim, a structural model with 4...

In this paper we give worked examples of adding national data to international datasets in order to add value to the secondary analysis of this data. We also show how more sophisticated techniques, including multilevel modelling and structural equation modelling, can be applied to such enhanced data to go beyond the potentially misleading simple correlational analysis. The paper is illustrated ...

in this study, the effect of environmental concern, attitudes and behaviors of the university students on the environmentally conscious purchasing behavior was investigated with the help of structural equation model (sem). sem is an effective data analysis tool that expresses the complicated causative relations between the latent variables. in this study, we collected the data from 400 univers...

the present paper aimed at studying the current models of credit portfolio management. there are currently three types of models which consider the risk of credit portfolio: the structural models (moody's kmv model, and credit- metrics model), the intensity models (the actuarial models) and the econometric models (the macro-factors model). the development of these three types of models is based...
