Frontiers of Literary Studies in China-Selected Publications from Chinese Universities 2016年第2期10卷 343-345页

作者： John A. Crespi Colgate university

In a sense, the title of Christopher Rea＇s book is misleading. It is not a newhistory of laughter in China; it is the ordyhistory of laughter in China. Calling the book a ＂history,＂ on the other hand, is less subject to dispute. The Age of Irreverence devotes meticulous attention to primary sources, and crafts its findings into a narrative of humor in popular culture from the turn of the twentieth century through the 1930s, with a nod in the epilogue toward the socialist era and beyond. As a scholarly intervention, however, the book＇s central argument most directly targets not history, but literary studies. The introductory chapter makes this clear in its discussion of ＂lost laughter＂; specifically, the idea that scholarly attention to trauma and suffering in modem Chinese literature has neglected a rich and heterogeneous discourse of fun that, in its time, engaged a huge audience of educated Chinese.

Aims: The aim of this study was to validate the Greek translation of the university of california, Los Angeles Loneliness Scale (UCLA) in Greek adults with HIV. Methods: The UCLA Loneliness scale (version 3) was administered to 140 people with HIV. Participants also completed the Greek Hospital Anxiety and Depression Scale (G-HADS). Validity and reliability analyses were performed. Results: The Cronbach’s α coefficient for the total UCLA score was 0.9. Test-retest reliability analysis in a subgroup of patients (n = 40) revealed good short-term stability over a 2-week interval (ICC 0.8 - 0.9, p < 0.0005). Exploratory factor analysis generated a three factors structure for the Greek translation. Convergent validity was supported through the scale’s high correlations with G-HADS anxiety (0.382, p < 0.01) and depression (0.524, p < 0.005). Conclusion: The Greek UCLA Loneliness scale (version 3) is a valid and reliable instrument that can be usefully implemented into clinical practice in order to diagnose and treat loneliness among the Greek HIV positive patients.

作者： Eric O.Potma Department of Chemistry University of California

In scanning probe microscopy(SPM),a sharp tip scans across a sample to produce an image with nanometer-scale resolution or better. SPM contrast is derived from the physical interplay between the tip and the sample. A special class of SPM techniques measures forces when the tip–sample junction is illuminated by an external light source. Photo-induced forces can be sensitive to the optical properties of the sample, thus enabling nanoscale imaging with spectroscopic,material-specific contrast.

Contrary to the current consensus, I argue that the existing evidence for high-temperature superconductivity in hydrides under high pressure is not compelling. I suggest that the focus of the field should urgently shift to establish unequivocally experimentally whether or not superconductivity in pressurized hydrides exists, instead of continuing to search for new materials that might show elusive signals of unproven superconductivity at ever higher temperatures. The implications of a negative finding for the theoretical understanding of superconductivity are discussed.

The search for magnetic topological materials has been at the forefront of condensed matter research for their potential to host exotic states such as axion insulators, magnetic Weyl semimetals, Chern insulators,etc. To date, the MnBi2nTe3n+1family is the only group of materials showcasing van der Waals-layered structures, intrinsic magnetism and non-trivial band topology without trivial bands at the Fermi level. The interplay between magnetism and band topology in this family has led to the proposal of various topological phenomena, including the quantum anomalous Hall effect, quantum spin Hall effect and quantum magnetoelectric effect. Among these, the quantum anomalous Hall effect has been experimentally observed at record-high temperatures, highlighting the unprecedented potential of this family of materials in fundamental science and technological innovation. In this paper, we provide a comprehensive review of the research progress in this intrinsic magnetic topological insulator family, with a focus on single-crystal growth, characterization of chemical disorder, manipulation of magnetism through chemical substitution and external pressure, and important questions that remain to be conclusively answered.
