From Inarticulacy to Care

This article seeks to critically re-open the closed structure of news coverage of ethnic minorities by proposing a dialogical model of representation, which evokes mutual understanding across differences through well-crafted narratives of minority experiences. Informed by Mikhail Bakhtin and Charles Taylor, it explores the notion of “dialogue” within journalistic narratives and delineates two dialogical approaches, namely the evaluative articulation of moral values and the polyphonic incorporation of different voices. The former suggests that journalists should employ nuanced languages to situate ethnic minorities’ aspirations and experiences in a common “horizon of significance”. The latter challenges the hegemonic monologue of an ostensibly objective narration and accentuates the manifold voices from ordinary people, urging the journalists to rethink their positionality as narrators. Two cases are analyzed to reveal how the dialogic representation can be realized in news reporting, calling for a transition from “ethics of inarticulacy” to ethics of care in journalism practices.

Smart responsive organic microlasers with multiple emission states for high-security optical encryption

Modern high-security cryptography and optical communication call for covert bit sequences with high coding capacity and efficient authentication. Stimuli-responsive lasing emissions with easily distinguishable readout are promising in the coding field as a novel cryptographic primitive, while the application is frequently restricted by the limited number of emission states. Here, we report a strategy of achieving multiple competitive lasing signals in responsive organic microspheres where a donor–acceptor pair was introduced. The competitive lasing from the donor and acceptor was reversibly switched by modulating the competition between the radiative rate of the donor and the rate of energy transfer, and the generated multiple lasing signals enabled a quaternary coding for recognizable cryptographic implementation. Data encryption and extraction were demonstrated using a 4 × 4 microlaser array, showing vast prospects in avoiding the disclosure of security information. The results offer a comprehensive understanding of excited-state dynamics in organic composite materials, which may play a major role in high-security optical recording and information encryption.

溴乙烷的水解和消去反应对比实验改进研究

卤代烃的水解和消去反应是高中化学教材选修五有机化学的重要反应。改进实验以溴乙烷为例,针对教材演示实验现象不明显、耗时较长等不足,设计溴乙烷水解和消去反应的对比实验,巧妙将溴乙烷的水解反应产物乙醇收集后用于作为消去反应的反应物。改进后的实验反应速率快、实验现象明显、操作方便,可在同一连续反应的装置中熟悉和掌握水解和消去反应的区别与联系,以及两者反应条件和产物的差异,有助于提高学生"宏观辨识与微观探析"的化学核心素养。
