Regional allocation of skills

This paper addresses three questions: (1) why does the share of skilledworkers in regional population tend to be higher in wealthier regions? (2)what determines changes in this share over time? and (3) why is it that internalmigration tends to raise average skill levels of the receiving regions relativeto that of the sending regions? I construct a two--region dynamic model withagglomeration and congestion to answer these questions. It is shown that,under certain relationship between wages and demand for land, unskilledworkers are discouraged more strongly from living in a wealthier region andare less mobile than skilled workers.

Improving How Listening Skills are Taught in the Efl Classroom: Guidelines to Producing Better Speakers of the English Language

This research paper is concerned with the need to improve how listening skills are taught in the Capeverdian EFL classroom. Teaching English through listening is not an easy task, especially when there are many factors that impede the learning process such as: lack of adequate materials and conditions; lack of qualified teachers with good pronunciation, and lack of innovative approaches to teaching listening skills. If our goal as teachers is to produce good English speakers we must invest in training good listeners. In this work I will focus on the following aspects: an evaluation of how effectively listening skills are taught in the Capeverdian EFL classroom; a look at how we can turn teaching problems into positive solutions; how to improve teaching listening skills and materials and recommendations for best practices in teaching listening skills in the EFL classroom. In conclusion I will include listening activities which reflect these best practices and offer recommendations for further research.

Early repolarization, acute emotional stress and sudden death.

We herein report the case of a 36-year-old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor.

Nonparametric bounds on the returns to language skills

This paper applies the theoretical literature on nonparametric bounds ontreatment effects to the estimation of how limited English proficiency (LEP)affects wages and employment opportunities for Hispanic workers in theUnited States. I analyze the identifying power of several weak assumptionson treatment response and selection, and stress the interactions between LEPand education, occupation and immigration status. I show that thecombination of two weak but credible assumptions provides informative upperbounds on the returns to language skills for certain subgroups of thepopulation. Adding age at arrival as a monotone instrumental variable alsoprovides informative lower bounds.
