The problem of unsupervised audio classification continuous to be a challenging research problem which significantly impacts ASR and Spoken Document Retrieval (SDR) performance. This paper addresses novel advances in audio classification for speech recognition. A new algorithm is proposed for audio classification, which is based on Weighted GMM Network (WGN). Two new high-level features: VSF (V...

this study is an attempt to develop a model of the simultaneous structure of the aggregate dynamic supply and demand to be used for estimation of parameters from data related to iran’s economy. the method for developing the model is an application of the dynamic and simultaneous process of aggregate supply and demand. obtained differential equations are used for solve the model. to estimate the...

Sundays Are Blue: Aren’t They? The Day-of-the-Week Effect on Subjective Well-Being and Socio-Economic Status This paper analyses whether individuals are influenced by the day of the week when reporting subjective well-being. By using a large panel data set and controlling for observed and unobserved individual characteristics, we find a large day-of the-week effect. Overall, we find a ‘blue’ Su...

Foreign direct investment (FDI) brings host countries capital, productive facilities, and technology transfers, as well as new jobs and management expertise. Thus, it is important to understand the basic reasons for FDI inflow and make clear what gains from FDI are. In the present paper, based on theoretical findings we formulate clear message stating that inflow of FDI does not need to be expl...

Gender Differences in Job Separation Rates and Employment Stability: New Evidence from Employer-Employee Data I analyze the job separation process to learn about gender differences in job separation rates and employment stability. An essential finding is that employer-employee data are required to identify gender differences in job separation probabilities because of labor market segregation. F...

Using 1985–1999 data from the German Socio-Economic Panel Study (GSOEP) to analyze wages we confirm the hypothesis that existing computer wage premiums are determined by individual ability or other unobserved individual characteristics rather than by productivity effects. While a rather large personal computer (PC) wage premium was found in the crosssectional regressions even after the inclusio...

Ambition and Jealousy: Income Interactions in the “Old” Europe versus the “New” Europe and the United States This paper asks how income distribution affects individual well-being and tries to explore the idea that this relation depends on the degree of mobility and uncertainty in the economy. It mostly concentrates on the relation between satisfaction and reference income (defined as the income...

This paper examines the causal relationship between growth and poverty reduction in developing countries between 1970 and 1998. For this purpose, we apply a modified form of traditional Granger causality tests to suit the short times series that are available, and use panel data model evaluation techniques to test the out-of-sample forecasting performance of competing models. We conclude that t...

An understanding of the spatial dimension of economic and social activity requires methods that can separate out the relationship between spatial units that is due to the effect of common factors from that which is purely spatial even in an abstract sense. The same applies to the empirical analysis of networks in general. We are able to distinguish between cross-sectional strong dependence and ...

Unlike policy makers‟ belief that geographical proximity to incumbent exporters encourages non-exporters to start exporting through positive information externalities, the empirical evidence in early studies is mixed. To make a contribution to fill the gap, this paper reexamines the relationship between the spatial and industrial agglomeration of exporting firms and the probability of being an ...
