How U.S. and Chinese journalists think about plagiarism

A comparison of 1,096 professional journalists in China and the United States on attitudes toward attribution and plagiarism reveals Chinese journalists were more likely to see attribution as a practice to be embraced regardless of career longevity and culture, suggesting journalistic norms are more important than a collectivist orientation. Attribution was more likely to be embraced by those who see principles as more important than expediency, affirming research that plagiarism is hardly a monolithic concept. Overall, journalists in the two nations did not vary significantly in their attitudes toward plagiarism, despite vast differences in culture and politics as well as evidence that in some other fields China is more accepting of reusing material without attribution. The data show that among journalists, attitudes toward plagiarism are shared across national boundaries, reinforcing related research showing that a journalism culture exists and is shared at least in part across national boundaries.

知识协同如何促进企业生态位演化？——基于青岛双星的案例研究

本文基于商业模式创新的理论视角,对“传统制造企业不同类型的知识协同行为如何驱动企业生态位演化”这一问题进行了嵌入式单案例研究。通过对青岛双星股份有限公司的案例分析,构建了“商业模式创新视角下知识协同驱动企业生态位演化的过程模型”。研究发现,在生态位第一次演化阶段,通过取长补短型知识转移促进效率型商业模式创新推动了企业生态位占据;在生态位第二次演化阶段,通过问题解决型知识共享促进新颖型商业模式创新推动了企业生态位扩展;在生态位第三次演化阶段,通过需求聚焦型知识创造促进锁定型商业模式创新推动了企业生态位深化。揭示了知识协同对企业生态位跃迁的作用机制,拓展了企业生态位演化的前因研究,为传统制造企业实现生态位跃迁提供了理论依据和实践启示。     

学生科学探究的自主性辨析

我国基础教育各门课程均强调科学探究,但对科学探究的界定却不甚明了,以致一些研究者片面强调学生与科学家的相似性以及学生的自主探究。通过国际研究发现,受学生认知水平、班额大小和课时等内外因素的影响,学生的科学探究需要在教师指导下进行,其指导程度应根据实际情况进行调整。

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.
