Et Tu, Torsten? This critique of my Economic Policy paper generates many emotions. It is certainly an honor for my research to be taken seriously by such an eminent scholar as my friend Torsten Persson. And while any publicity is good, a negative citation dominates a positive one. There is irony; I came up with the original idea in a hallway conversation with Harry Flam a few feet from Persson’...

A traditional view of the nature of species holds that populations within species maintain genetic cohesion through substantial intraspecific gene flow and that the whole genome of a species is protected from interspecific gene flow by strong reproductive isolation. Both aspects of this view have been challenged. Reproductive barriers between recently evolved species can be incomplete and perme...

This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological informatio...

Two new species of Dolichothele Mello-Leitão, 1923 are described from Brazil and Bolivia, D. mottaisp. n. from Distrito Federal and the state of Goiás, Brazil, and D. camargorumsp. n. from the state of Rondônia, Brazil, and the La Paz region, Bolivia. Males of the two new species resemble Dolichothele bolivianum (Vol, 2001) in having a small subapical keel on the distal embolus and females in p...

The concept of using an optical fibre to map dynamic perturbations along the sensing fibre was first proposed by Taylor et al. (Taylor 1993) in 1993 and later demonstrated by his team in 2005 (Juarez 2005). The proposed sensor was only capable of detecting the dynamic perturbations along the sensing fibre by monitoring the changes in the pattern of the backscattered coherent Rayleigh noise (CRN...

I noticed with interest the article “Pesticide Spraying for West Nile Virus Control and Emergency Department Asthma Visits in New York City, 2000” by Karpati et al. (2004). I am a physician who treats hundreds of patients with chronic illness from chemical overexposure. Many of these patients have toxic encephalopathy, reactive airway disease, and other chemically induced organ system damage. W...

health reforms that emphasize public health and improvements in primary care can be cost-effective measures to achieve health improvements, especially in developing countries that face severe resource constraints. in their paper “shanghai rising: health improvements as measured by avoidable mortality since 2000,” gusmano et al suggest that shanghai’s health policy-makers have been successful in...

The association of harmful forms of illicit drug use with serious mental health problems is a key issue for national and international drug policy. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) refers to ‘comorbidity/ dual diagnosis’ as the ‘temporal coexistence of two or more psychiatric disorders as defined by the International Classification of Diseases, one of which i...
