in recent decades, the concept of cultural capital has created a lot of scientific studies over the world in the sociology of education. these studies mainly based on the two models: bourdieu's cultural reproduction and dimaggio's cultural mobility. these have achieved different results. this study aimed at evaluating the theoretical models in an empirical condition. middle and high school stud...

In most stochastic inventory models, such as continuous review models and periodic review models, it has been assumed that the stockout period during a cycle is small enough to be neglected so that the average number of cycles per year can be approximated as D/Q, where D is the average annual demand and Q is the order quantity. This assumption makes the problem more tactable, but it should not ...

This paper presents a keyword spotting method based on searching a syllable lattice structure. The Mandarin syllables are represented in initial-final models. By one-stage dynamic programming, an utterance is converted into a sequence of topN-candidate syllables. It comes out a syllable lattice structure for this input utterance. A vocabulary of predefined keywords is represented as a set of sy...

This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...

The task of keyword spotting is to detect a set of keywords in the input continuous speech. In a keyword spotter, not only the keywords, but also the non-keyword intervals must be modeled. For this purpose, filler (or garbage) models are used. To date, most of the keyword spotters have been based on hidden Markov models (HMM). More specifically, a set of HMM is used as garbage models. In this p...
