对历史客观题史料选择的探讨——以2021年某省高考历史卷第6题为例

历史客观题在设置题干情境信息时,应尽可能选用那些能够反映事件核心属性、揭示事件主旨特征的关键性史料,而力戒对史料进行片面的裁剪和择取那些枝蔓性、辅助性和偏颇性的史料,这是对史料信息做出准确解释和深刻认知的前提与重要保证,也是发挥史料实证功能的内在要求。唯有如此,才能发挥出历史客观题的正确导向功能。

Novel master–slave synchronization criteria of chaotic Lur’e systems with time delays using sampled-data control

This paper investigates the problem of master–slave synchronization of chaotic Lur’e systems (CLSs) with time delays by sampled-data control. First, a novel Lyapunov–Krasovskii functional (LKF) is constructed with some new augmented terms, which can fully capture the system characteristics and the available information on the actual sampling pattern. In comparison with existing results, the constraint condition of the positive definition of the LKF is more relax, since it is positive definite only requiring at sampling instants. Second, based on the LKF, a less conservative synchronization criterion is established. Third, the desired estimator gain can be designed in terms of the solution to linear matrix inequalities (LMIs). The obtained conditions ensure the master–slave synchronization of CLSs under a longer sampling period than remarkable existing works. Finally, three numerical simulations of Chua’s circuit and neural network are provided to show the effectiveness and advantages of the proposed results.

指向大规模测量建构的学生参与研究评析

以往研究者对学生参与的概念、建构、测量工具、影响因素和影响后果做了较为细致的研究.为了在中国语境下延续这一话题研究,需要对学生参与及其相关概念进一步做出明确区分,结合我国实际数据研发本土化检测工具,并且开展影响因素和影响后果的实证研究,为提高广大学生的参与水平做准备.     

工作压力类型及其绩效和离职倾向差异分析——以大学教师为例

依据压力交互作用理论,结合939份问卷调查结果,从压力感和压力反应两个维度,把大学教师工作压力状况划分为高压力感、高压力反应等四种类型,综合分析压力源和压力反应对教师工作绩效和离职倾向产生的影响。结果表明高压力感对工作绩效的不同维度具有正向促进作用,而高压力反应对离职倾向则更具有预测力。这些结论不同于"高压力感造成了工作绩效下降和离职倾向升高"的传统观点。     

Distinct neuron populations for simple and compound calls in the primary auditory cortex of awake marmosets

Marmosets are highly social non-human primates that live in families. They exhibit rich vocalization, but the neural basis underlying this complex vocal communication is largely unknown. Here we report the existence of specific neuron populations in marmoset A1 that respond selectively to distinct simple or compound calls made by conspecific marmosets. These neurons were spatially dispersed within A1 but distinct from those responsive to pure tones. Call-selective responses were markedly diminished when individual domains of the call were deleted or the domain sequence was altered, indicating the importance of the global rather than local spectral-temporal properties of the sound. Compound call-selective responses also disappeared when the sequence of the two simple-call components was reversed or their interval was extended beyond 1 s. Light anesthesia largely abolished call-selective responses. Our findings demonstrate extensive inhibitory and facilitatory interactions among call-evoked responses, and provide the basis for further study of circuit mechanisms underlying vocal communication in awake non-human primates.
