In this paper we seek to explain the behavior of the long term interest rate in the U.S. over the last 50 years using the idea that investors had only limited information about the process generating short term interest rates. Investors are assumed to behave according to the expectations hypothesis of the term structure but use econometric methods to learn about the appropriate model for short ...
Causal structure learning from time series data is a major scientific challenge. Extant algorithms assume that measurements occur sufficiently quickly; more precisely, they assume approximately equal system and measurement timescales. In many domains, however, measurements occur at a significantly slower rate than the underlying system changes, but the size of the timescale mismatch is often un...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
Hierarchical analysis is one of the prioritization methods of phenomena. This method provides comparison and use of expert people. In this research, the men-tioned method was applied in order to weight and prioritize valuation factors and indicators for applied science in primary school. The methodology of this research is descriptive survey. The statistical population is all experts (education...
