面对错综复杂和快速变化的商业环境,组织要想做出快速响应,领导者的有效倾听显得非常重要。通过文献综述发现,现有研究尚未对领导倾听的概念形成统一界定,且理论视角和研究层次较为单一,这不利于我们深入理解领导倾听的内涵及其多层次效应。事实上,作为一种领导行为,领导倾听不仅会对领导者自身产生影响,而且会给团队及其下属带来影响。因此,本研究基于二元互动情境,从沟通信息和支持员工两方面对领导倾听的内涵进行探索性研究,并从领导力效能的评价对象(领导者、团队、员工)出发,结合多层次、多理论、多研究方法的全景研究范式逐步揭示领导倾听对不同对象的不同效应、黑箱机制及边界条件。本研究不仅开拓了倾听研究的新思路和新视角,而且为企业增强领导倾听的积极效能提供了管理启示。

The annular volute is typically used in a slurry pump to reduce the collisions between solid particles and the volute tongue and to achieve a better resistance to blocking. However, only limited studies regarding annular volutes are available, and there is no systematic design method for annular volutes. In this study, the influence of volute casing cross-sectional flow area on the hydraulic loss, pressure pulsations, and radial force under varying working conditions in a centrifugal ceramic pump are discussed in detail. Experimental tests were conducted to validate the numerical results. The results indicated that, when the volute casing flow area increases, the hydraulic performance decreases marginally under the rated working conditions, but increases at the o-design points, specifically under large flow condition. However, the volute casing with a larger flow area has a wider high-e ciency region. In addition, the increase in the volute casing flow area will decrease the pressure pulsations in the volute, regardless of the working condition, and decrease the radial force on the shaft, therefore, providing an improved pump operational stability. It is anticipated that this study will be of benefit during the design of annular volutes.

Relativistic outflows often exhibit extreme observational characteristics due to beaming effects, which makes measuring their jet power a challenging task. Although the spectral energy distribution(SED) obtained from multi-wavelength data can constrain the physical parameters of these jets, accurately estimating the Doppler factor remains difficult. To address this challenge, we assemble a comprehensive sample containing available SEDs of synchrotron and inverse Compton(IC) components, monochromatic luminosity, and broad-line region(BLR) emissions. We employ a parabolic equation to fit the synchrotron radiation SEDs,constraining jet physical parameters within the framework of a one-zone leptonic model. Our study delves into the jet properties and Doppler factor estimations, yielding the following key findings:(1) The fitting results of SED data for the entire sample reveal normal distributions of jet physical parameters for two subclasses of blazars.(2) Correlation analysis demonstrates that synchrotron peak luminosity exhibits a proportional relationship with both the radio and the γ-ray luminosities.(3) We introduce a novel method for estimating Doppler factors, which uncovers discrepancies between Doppler factors from this work and others from different techniques.
