Kernel-type estimators for the distortion risk premiums of heavy-tailed distributions

A new kernel-type estimator for the distortion risk premiums of heavy-tailed losses is introduced. Using a least-squares approach, a bias-reduced version of this estimator is proposed. Under suitable assumptions, the asymptotic normality of the given estimators is established. A small simulation study, to illustrate the performance of our method, is carried out.     

The High‐Rise Home: Verticality as Practice in London

This article investigates the relationship between verticality and home. It develops the idea of ‘verticality as practice'. This appreciates verticality not as something that takes place in three‐dimensional landscapes, but as the outcome of everyday practical activity. Examining a modernist high‐rise estate, the Aylesbury Estate in London, the article identifies and examines a range of vertical practices, illustrating how they are intertwined with home. Vertical practices, such as those associated with the view, help to make a unique and special home, becoming intensely meaningful to residents. However, they also unmake dimensions of home when they interact with the estate's marginality.

Promoting Giving Campaigns in University Websites: A Cross-cultural Comparison between the United States and South Korea

ABSTRACT

This study was designed to compare the ways the websites promote giving campaigns between the United States and South Korea. Furthermore, this study explored how the campaign appeals are associated with the distinct cultural values between universities in the United States and Korea. Guided by a content analysis of 200 universities in the United States and South Korea, the findings of this study demonstrated that, compared to the Korean university websites, U.S. university websites more frequently targeted university-affiliated donors, including alumni, students, parents, and so forth, and used multimedia-based exemplars about the giving campaigns.
