This study does not simply count the number of migrants, it also examines the attributes of migrants to determine the human capital, or productive skills, they possess and are willing to provide to the market. Each person, due to characteristics such as education and work experience, has a different level of skill. While there is no way to identify exactly how much human capital a person posses...

This paper tests whether aggregate matching is consistent with unemployment being mainly due to search frictions or due to job queues. Using U.K. data and correcting for temporal aggregation bias, estimates of the randommatching function are consistent with previous work in this field, but random matching is formally rejected by the data. The data instead support ‘stock-flow’ matching. Estimate...

one of known methods for measuring, forecasting and managing risk is value at risk, which recently has been used by financial institutions extensively. value at risk (var) is a method for recognizing and evaluating risk and uses standard statistical techniques that have daily using in other contexts. this research is seeking a career for managing investment risk in stock exchange and selection ...

Public–private sectoral wage differentials have been studied extensively using quantile regression techniques. These typically find large public sector premiums at the bottom of the wage distribution. This may imply that low skill workers are ‘overpaid’, prompting concerns over efficiency. We note several other potential explanations for this result and explicitly test whether the premium varie...

In 2013, Canadian scholars delivered a 1-week workshop to 30 junior public health professionals in Rwanda. The goal was to improve the Rwandans' skills and confidence with respect to writing scientific papers for submission to international peer-reviewed global health journals. As a result of the workshop, there was a statistically significant improvement in participants' reported confidence in...

There are differences in the way infants learn, perceive, and understand the environment as compared to adults (Bornstein, 1989; Nelson, 2000; Craik and Bialystok, 2006). While an adult has an established, clear perception of his environment, infants are still forming perceptions of the world (Hall et al., 1989; Holt, 1991; Zitelli and Davis, 2007). The mechanisms underlying these differences a...

Novel experience and learning new skills are known as modulators of brain function. Advances in non-invasive brain imaging have provided new insight into structural and functional reorganization associated with skill learning and expertise. Especially, significant imaging evidences come from the domains of sports and music. Data from in vivo imaging studies in sports and music have provided vit...

This study presents a statistical downscaling (SD) method for high-altitude, glaciated mountain ranges. The SD method uses an a priori selection strategy of the predictor (i.e., predictor selection without data analysis). In the SD model validation, emphasis is put on appropriately considering the pitfalls of short observational data records that are typical of high mountains. An application ex...

This paper presents a multi-stock discrete time market model. In this model, we consider an optimal solution in the multi-stock portfolio selection. Specially, the model allows that the optimal strategy to maximize an exponent function of the expected value is quasi myopic.

We propose a new computational method of input selection for stock market forecasting with neural networks. The method results from synthetically considering the special feature of input variables of neural networks and the special feature of stock market time series. We conduct the experiments to compare the prediction performance of the neural networks based on the different input variables b...
