在乡村振兴战略背景下,城市居民的乡村度假旅游有助于推动城乡融合,探明城市居民的乡村度假行为机制对于乡村度假旅游的发展具有积极意义。文章依托“情感认知评价”理论,构建环境认知对乡村寄宿避暑度假者忠诚度的影响模型,以江西靖安县三坪村为案例地,探讨乡村寄宿避暑度假者忠诚度的影响因素及作用机制。结果表明:第一,环境认知对度假者忠诚度有显著正向影响;第二,地方依恋在环境认知对度假者忠诚度的影响关系中具有中介作用;第三,幸福感在环境认知对度假者忠诚度的影响关系中具有中介作用;第四,地方依恋与幸福感在度假者环境认知和忠诚度之间具有链式中介效应。文章揭示了城市居民乡村度假行为机制,拓展了地方依恋理论的应用领域,可为乡村度假旅游发展提供参考。

【目的】基于司法案件异构属性图,提出一种高效的案件相似度计算模型,用于提升案件相似度比较的速度和精确率。【方法】以案件的法律文书内容及其他相关信息构建案件异构属性图,将案件文本相似性问题转化为图相似性问题,结合图注意力网络和邻域节点共识匹配,能够有效学习到司法案件异构属性图的局部信息和全局信息,进而计算案件的相似度。【结果】在2019年中国法研杯的相似案例匹配数据集上,所提出模型在计算量(FLOPs)仅有冠军模型1.02%的情况下,达到了优于冠军模型的结果。【局限】本文模型的精度与属性图构建的复杂性呈正相关,但通过离线方式预先构建案件异构属性图,不会影响算法的时间复杂度。【结论】基于司法案件异构属性图有效利用了司法领域文本中的深度语义和法律主客体之间的隐含信息,提升了案件相似度比较的速度和精确率。

Increased penetration of wind energy in the electric grid has necessitated studying the impact of wind integration on the transient stability of the power system,with urgency to develop appropriate electromechanical models of the wind turbine generator(WTG).The representation and control of the WTG’s electric signals are typically in a rotational dq coordinate system whose reference angle is provided by a phase-lockedloop(PLL).The PLL is commonly considered as a measurement device and is often absent in existing WTG electromechanical *** paper studies the impact of PLL on the DFIG-based WTG electromechanical response by theoretical and simulation *** dynamics of the PLL are found to greatly influence the WTG electromechanical response,suggesting that PLL should be regarded as an indispensable control loop rather than a measurement device,and its impact should be modeled when establishing the WTG electromechanical model.
