Hidden regular variation defines a subfamily of distributions satisfying regular variation on E = [0,∞]\{(0, 0, · · · , 0)} and models another regular variation on the sub-cone E = E\∪di=1 Li, where Li is the i-th axis. We extend the concept of hidden regular variation to sub-cones of E (2) as well. We suggest a procedure for detecting the presence of hidden regular variation, and if it exists,...

The Mediterranean species of the genus Mitromorpha Carpenter, 1865 as currently conceived, are herein reviewed. The genus is represented in the Mediterranean Sea by eleven species, of which seven are here described as new, all included conservatively in the subgenus Mitrolumna Bucquoy, Dautzenberg & Dollfus, 1883: Mitromorpha (Mitrolumna) columbellaria (Scacchi, 1836), Mitromorpha (Mitrolumna) ...

The article by Mitra and colleagues in this issue of the Journal presents an interesting scenario on arsenic contamination from Bangladesh (1). The paper further confirms the health effects of arsenic and contributes to the literature, especially regarding the inverse relationship between body mass index and the duration of disease. Many tubewells in Bangladesh have been contaminated with arsen...

* We thank Amil Petrin and Ken Train for providing guidance on the application of their methods. We have benefited by helpful suggestions and insights from Lee Branstetter, Judith Dean, Devashish Mitra, and seminar participants at the NBER China Working Group Meetings, the University of Nottingham, and the 2010 AEA meetings. Abstract Deeper international integration through an inflow of foreign...

In this paper, a method for measuring the perceptual image quality of JPEG-2000 coded images has been proposed. The image quality is characterized by the average edgespread in the image, or more specifically the average extent of the slope’s spread of an edge in the opposing gradients’ directions. The proposed method is, in effect, a way of measuring the amount of blurring in the image. The eff...
