王梵志诗“不善广平王”校注商兑

王梵志诗＂不善广平王＂,前贤的校注或存疑,或相左。从训诂释义及敦煌写卷别本字形两方面可以证明,＂善＂字当校为＂若＂字;从历史故实、生活经验及语义表达及用韵的实际情况需要等方面可以证明,＂广平王＂不误。     

虚拟微语境差异与机构话语的语用策略运用

面对面交流中,机构话语的语用策略运用比较稳定,然而在虚拟语境下却发生了变化。其中,交互轮次的显著差异构成了两种不同氛围的微环境。本文以医患对话中患者首轮咨询使用的语用策略为研究对象,采用定量分析的手段对比了八种策略在不同微环境中的使用差异。结果显示三种积极礼貌策略和两种消极礼貌策略呈现出显著差异,而另外两种消极礼貌策略和一种非礼貌语用策略则没有达到显著性水平。以上结论为进一步开展虚拟语境定量话语分析提供了借鉴。     

职校生技能满意度与学习动机关系研究

采用技能满意度量表与学习动机量表对职校生进行问卷调查,主要是为了探讨职校生技能满意度与学习动机的特点及两者之间的关系。研究表明,职校男女生在技能满意度及各维度得分上存在某些差别,但差异性不显著;各年级学生在学校满意度上存在显著性差异,学习动机方面不存在显著的性别与年级差异。技能满意度各维度与学习动机两个维度之间存在显著正相关。

Ultrabithorax is a key regulator for the dimorphism of wings,a main cause for the outbreak of planthoppers in rice

Rice planthoppers, the most devastating rice pests, occur in two wing forms: the short-wing form for rapid population growth and long-wing form for long-distance migration, which together create the mechanism for outbreak. Here we show that Ultrabithorax (Ubx) is a key regulator for switching between the long- and short-wing forms of rice planthoppers. Ubx is expressed in both forewing and hindwing pads, which is different from the canonical model of Ubx expression. In brown planthoppers, expression of Ubx (NlUbx) is regulated by nutritional status of the rice host. High-quality young plants induce NlUbx expression leading to the short-wing form; low-quality ripe plants reduce NlUbx expression resulting in long-wing form. We also showed that NlUbx is regulated by the insulin receptors NlInR1 and NlInR2. The default expression of NlInR1 inhibits NlUbx resulting in long-wings, while high-quality hosts induce NlInR2 expression, which represses NlInR1 thus promoting NlUbx expression to produce short-wings.     

Superconductivity in chromium nitrides Pr3Cr10-xN11 with strong electron correlations

Exploration of superconductivity in Cr-based compounds has attracted considerable interest because only a few Cr-based superconductors (CrAs, A₂Cr₃As₃ and ACr₃As₃ (A = K, Rb, Cs, Na)) have been discovered so far and they show an unconventional pairing mechanism. We report the discovery of bulk superconductivity at 5.25 K in chromium nitride in Pr₃Cr_10-xN₁₁ with a cubic lattice structure. A relatively large upper critical field of H_c2(0) ∼ 12.6 T is determined, which is larger than the estimated Pauli-paramagnetic pair-breaking magnetic field. The material has a large electronic specific-heat coefficient of 170 mJ K⁻² mol⁻¹—about 10 times larger than that estimated by the electronic structure calculation, which suggests that correlations between 3d electrons are very strong in Pr₃Cr_10-xN₁₁, and thus quantum fluctuations might be involved. Electronic structure calculations show that the density of states at the Fermi energy are contributed predominantly by Cr 3d electrons, implying that the superconductivity results mainly from the condensation of Cr 3d electrons. Pr₃Cr_10-xN₁₁ represents a rare example of possible unconventional superconductivity emerging in a 3D system with strong electron correlations. Nevertheless, clarification of the specific pairing symmetry needs more investigation.
