Although forms of address are widely used in textual and other types of disclosure, empirical evidence of their effects is rare. China provides a unique setting in which to test the economic consequences of the forms of address used in audit reports. From 2003 to 2011, about 60% of auditors surveyed addressed their clients by their real names in audit opinions, while the others used honorifics. Based on a sample of Chinese audit opinions, I report the following findings. First, the announcement of an audit opinion that uses the client’s real name elicits a greater market response than the announcement of an opinion featuring an honorific form of address. Second, the effects of real-name forms of address are stronger in firms with weak board governance. Third, the association between audit fees and audit risk factors, such as loss-making, is stronger in firms that are addressed by their real names in audit reports. I conclude from these findings that the forms of address used in audit opinions may reveal private information on audit quality. The results of this study are consistent with the power-solidarity effect described by sociolinguists.

Perspective is a distinctive feature of external perception. There is a question of how to account for perceptual constancy in spite of changing perspectives. Alva Noe proposes the notion of ＂perspectival property＂ [P-property] and appeals to the perspectival aspect of perceptual content. His proposal conflicts with perceptual experiences and hence incurs many criticisms. Drawing on Husserl＇s phenomenology and Gibsonian psychology, I propose the notion of ＂perspectival awareness＂ [P-awareness]. I will argue that P-awareness is embodied pre-thematic self-awareness instead of the experience of a special kind of objective property. With the notion of P-awareness in mind, I then elaborate on the embodied subjective feature of perspective.

In this work, a novel heterojunction composite Ag_(2)S/KTa_(x)Nb_(1-x)O_(3)was designed and synthesized through a combination of hydrothermal and precipitation procedures. The Ta/Nb ratio of the KTa_(x)Nb_(1-x)O_(3)and the Ag_(2)S content were optimized. The best 0.5% Ag_(2)S/KTa_(0.5)Nb_(0.5)O_(3)(KTN) sample presents an enhanced photocatalytic performance in ammonia synthesis than KTN and Ag_(2)S. Under simulated sunlight, the NH_(3)generation rate of 0.5% Ag_(2)S/KTN reaches 2.0 times that of pure KTN. Under visible light, the reaction rate ratio of the two catalysts is ***, XPS, and TEM analysis revealed that Ag2S was intimately decorated on the KTN nanocubes surface, which promoted the electron transfer between the two semiconductors. The band structure investigation indicated that the Ag_(2)S/KTN heterojunction established a type-Ⅱ band alignment with intimate contact, thus realizing the effective transfer and separation of photogenerated carriers. The change in charge separation was considered as the main reason for the enhanced photocatalytic performance. Interestingly, the Ag_(2)S/KTN composite exhibited higher NH3generation performance under the combined action of ultrasonic vibration and simulated sunlight. The enhanced piezo-photocatalytic performance can be ascribed that the piezoelectric effect of KTN improved the bulk separation of charge carriers in KTN. This study not only provides a potential catalyst for photocatalytic nitrogen fixation but also shows new ideas for the design of highly efficient catalysts via semiconductor modification and external field coupling.

Magnetic titanium dioxide core-shell nanoparticles（Fe3O4@TiO2 NPs） were synthesized as particles withappropriate size for intravenous injection. They subsequently were functionalized with p-aminothiophenol（PATP） tofacilitate the covalent attachment of target drugs through azo coupling reaction, which can be universally observed ina variety of drugs containing phenols, anilines, and imidazoles. The proposed drug nanocarrier was designed to po-ssess the ability to release drugs upon UV irradiation because of the photocatalytic property of the TiO2 shells. All theresults indicate the potential application of the Fe3O4@TiO2 NPs in targeted drug delivery with greater chemical sta-bility and universality.
