Nonparametric inference of doubly stochastic Poisson process data via the kernel method

Doubly stochastic Poisson processes, also known as the Cox processes, frequently occur in various scientific fields. In this article, motivated primarily by analyzing Cox process data in biophysics, we propose a nonparametric kernel-based inference method. We conduct a detailed study, including an asymptotic analysis, of the proposed method, and provide guidelines for its practical use, introducing a fast and stable regression method for bandwidth selection. We apply our method to real photon arrival data from recent single-molecule biophysical experiments, investigating proteins' conformational dynamics. Our result shows that conformational fluctuation is widely present in protein systems, and that the fluctuation covers a broad range of time scales, highlighting the dynamic and complex nature of proteins' structure.Comment: Published in at http://dx.doi.org/10.1214/10-AOAS352 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

The Myth of the City Image in Contemporary Chinese Society

In the past three decades, China\u27s cities have experienced rapid urbanization in a transitional political and economic environment; correspondingly, the city image has become one of the most important symbols of the progress in Chinese development. Within the Chinese mainstream media, the transformation of the city image has long been heralded as a successful microcosm of Chinese political and economic reforms. However, the social reality behind the prosperous facade of the city\u27s image is that city leaders are reshaping urban spaces to cater to the needs of the dominant class, multinational corporations, and global capitalism. Moreover, the construction of the city\u27s image obfuscates the widening gap between rich and poor, class conflicts, and the reconstitution of capitalist class power. I hypothesize that the idea of the contemporary city image is a myth, and intend to reveal the meanings and connotations which the myth conceals. More specifically, I conduct a case study of the 2008 Beijing Olympic campaign by comparing the representation of the city image offered by mainstream and alternative media sources. I examine how the mainstream media helped to construct the myth in accordance with government directives and how it was contested within the alternative media. In this way, I explore the power relations and class struggle behind the myth from a social justice perspective

Developing a Scale to Measure Destination Gender

Whether they depict the rugged landscape of the American West or the seductive charm of a South Asian beach, photographs and their accompanying text are powerful drivers of tourism demand. But what lies behind our response to such tourism tropes? Rosen College researchers have produced a new study which reappraises destination marketing through a gender-based lens. Led by Dr. Tingting Zhang, the study has developed and validated a cross-cultural scale to determine ‘destination gender’, or whether a location should be thought of as having masculine or feminine gender traits and appeal
