领导力发展是组织管理领域的前沿研究主题,也是人力资源管理实践中亟待突破的现实问题。过往研究多关注组织内部培训和挑战性工作经历对领导力发展的促进作用,但成效提升存在瓶颈。新的研究趋势强调跨领域的“全人”发展,特别是非工作场景经验对领导力发展的重要作用。本文采用“家庭−工作增益”理论视角,探讨父母角色经验如何通过工具性、情感性和效率性增益路径影响领导角色有效性,在理论层面上提出基于“父母−领导增益”视角的领导力发展模型。未来研究可明确父母角色经验和领导角色有效性之间的定性和定量关系,并尝试从强化增益意识等方面开展干预研究,以促进实践中的领导力发展。

汉语既是话题凸显型语言,又是主观性凸显的语言,以前的研究很少将汉语的这两个特征关联起来,也没有仔细深入研究过话题构式主观性产生的理据。本研究从话题的空间性、述题的时间性的维度阐释时空性与汉语话题构式主观性的内在关联。本文把时空性视为一个由弱到强的连续体。话题的空间性越弱、述题的时间性越弱,该构式表达的主观性越强。时空性与话语的主观性在两个维度实现内在关联:1)时空性越弱,时空定位不断泛化,越接近思维与语言的虚拟性,越能实现认知上的主观能动性,主观性就越强;2)时空性越强,时空定位越准确,客观性就越强。

A method for moving object recognition and tracking in the intelligent traffic monitoring system is presented. For the shortcomings and deficiencies of the frame-subtraction method, a redundant discrete wavelet transform （RDWT） based moving object recognition algorithm is put forward, which directly detects moving objects in the redundant discrete wavelet transform domain. An improved adaptive mean-shift algorithm is used to track the moving object in the follow up frames. Experimental results show that the algorithm can effectively extract the moving object, even though the object is similar to the background, and the results are better than the traditional frame-subtraction method. The object tracking is accurate without the impact of changes in the size of the object. Therefore the algorithm has a certain practical value and prospect.

Mechanical stimulation technology is critical in agricultural crop production because it is constantly regarded as a developing green technology to regulate plants to meet people's need for green and healthy agricultural products. Various environmental mechanical stimulation impacts seed germination, seedling growth, flowering date, fruit quantity, and fruit quality throughout the life cycle of a horticultural plant. This study first outlines the basic characteristics of six types of common mechanical stimulation in nature:precipitation, wind, gravity,touch, sound, and vibration. The effects of various mechanical stimulation types on the seed, seedling, flowering, and fruit of horticultural plants throughout their whole life cycle are then presented, as reviewed in the recent 100 years of existing literature. Finally, potential future study directions are discussed. The main challenge in mechanical stimulation technology is to uncover its potential capabilities for regulating and controlling plant development and fruit quality in green agriculture instead of agricultural chemicals.

The Luzon Strait is the main impact pathway of the Kuroshio on the circulation in South China Sea （SCS）. Based on the analysis of the 1997–2007 altimeter data and 2005–2006 output data from a high resolution global HYCOM model, the total Luzon Strait Transport （LST） has remarkable subseasonal oscillations with a typical period of 90 to 120 days, and an average value of 1.9 Sv into SCS. Further spectrum analysis shows that the temporal variability of the LST at different depth is remarkable different. In the upper layer （0–300 m）, westward inflow has significant seasonal and subseasonal variability. In the bottom layer （below 1 200 m）, eastward outflow exhibits remarkable seasonal variability, while subseasonal variability is also clear. In the intermediate layer, the westward inflow is slightly bigger than the eastward outflow, and both of them have obvious seasonal and subseasonal variability. Because the seasonal variation of westward inflow and eastward outflow is opposite, the total transport of intermediate layer exhibits significant 50–150 days variation, without obvious seasonal signals. The westward Rossby waves with a period of 90 to 120 days in the Western Pacific have very clear correlationship with the Luzon Strait Transport, this indicates that the interaction between these westward Rossby waves and Kuroshio might be the possible mechanism of the subseasonal variation of the LST.

应用热分析仪对柠条生物质燃料的燃烧过程进行分析,研究颗粒度、升温速率和风量对燃烧特性与动力学参数的影响。结果表明:(1)颗粒度为0.16 mm试样在升温速率为20 K/min,风量为40 mL/min的工况下,着火温度为221.1℃,最大燃烧速率温度为336.2℃,燃尽温度为559.4℃,最大燃烧速率0.6 mg/min,平均燃烧速率为0.129mg/min,相对于10 K/min和30 K/min升温速率,20 K/min工况下的燃料动力学参数最优,活化能为39.094 kJ/mol,频率因子为2.175×10~7L/min;(2)升温速率的增大会使平均燃烧速率和燃烧特性指数增大,着火温度降低;风量对燃烧速率无影响,但较大风量不利于挥发分析出和燃烧稳定性;颗粒度对挥发分析出有显著影响,颗粒度较大时需较高升温速率和风量才可充分燃烧,而颗粒度较小时即使风量较小也能充分燃烧。
