学术创业企业从0到1的成长

学术创业企业的成长伴随着从科研网络向产业网络的跨越,为了解析其成长机理,本文以中美两国共14个学术创业案例为依据,从“社会网络—合法性”视角分析企业网络的动态演化,并着重探讨了各阶段合法性约束的种类、身份转化劣势的作用机制以及合法性策略选择的情境条件。研究发现：（1）学术创业者在创业者存在身份转换劣势,并给企业带来合法性约束。（2）根据网络边界跨越方式的不同,创业者建立合法性的策略可分为直驱型策略和迂回型策略。（3）合法性策略的选择受到企业所在网络的多样性和自身技术新颖性的影响。基于学术创业的特殊情境,论文提出身份转换劣势的概念,并为企业成长理论和合法性理论做出贡献。

Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing

Complex oxides with tunable structures have many fascinating properties, though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach. Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic (1-x)BiTi_(1-y)/2Fe_yMg_(1-y)/2O₃–(x)CaTiO₃ (BTFM–CTO) solid solution in large area, confirming its ferroelectricity at the atomic scale with strong spontaneous polarization. Careful compositional tuning leads to a bulk magnetization of 0.07 ± 0.035 μ_B/Fe at room temperature, enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0 × 10⁻⁷ s/m. This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film, making it possible to explore a much wider space of composition, phase, and structure that can be easily scaled up for industrial applications.

Xu Beihong and the New China: thoughts centered on the painting At the World Peace Congress

This essay analyses a politically tinged painting by Xu Beihong (1895–1953), a representative modern Chinese painter. He composed the work in 1949, just before the founding of the People’s Republic of China, or the New China. In this article’s discussion of the perplexing work, the author attempts to unveil Xu’s understanding of revolution and of the relationship between art and politics, in relation to his difficulties in exploring and practicing art in the early Republic period (1912–1949). Based on this, the author discusses the painter’s mindset in the social and political context of the New China. She also tries to reveal that Xu’s art practices were restrained by the realities he was in – a crucial point to understanding his achievements and predicaments. As an artist who resisted the western modernism in the course of modernization, and who idealistically pursued the highest good and beauty through “realist” approaches and historical expressions, Xu’s predicaments interestingly reflect the complicated relationship between art and revolution in China’s road to modernization, and provide a foundation for further explorations into the core issues and the particularity of modern Chinese paintings.
