In the change management literature, most studies on recipients' resistance to change include only the views of agents or of recipients, thereby ignoring that these parties may have different perceptions. In this quantitative study, we include the perceptions of both parties in studying the recipients' resistance and the impact of the agent's leadership behavior. In a sample of 117 agent-recipients groupings, covering 110 different change projects in 90 organizations, we found that agents perceive higher levels of recipients' resistance than do the recipients themselves. Additionally, we found that agents who create space to enable recipients to think and act differently (by employing creating behavior) report higher levels of recipients' resistance, whereas recipients perceive their resistance to be lowered when agents facilitate an emotional connection to the change (framing behavior). The depth of the change appeared to moderate the relationship between agent's leadership behavior and recipients' resistance, indicating that agents and recipients differ in which change leadership behaviors they perceive as increasing or decreasing resistance at different levels of change depth. These findings imply to reconsider the relationship between agent and recipients and we propose some promising avenues for future studies in resistance research.  相似文献

羌族剪纸是羌族文化艺术的精华。经历了2008年“汶川大的地震”、灾后重建、城镇化发展之后,羌族剪纸的“文化语境”正发生着较大变化。以茂县羌族剪纸为例,其变化的外部原因包括现代流行服饰的融入、自然灾害、城镇化进程以及茂县手画花样市场的兴起对花样剪纸的冲击等,而内部原因则表现为传统习俗的变化、宗教祭祀的淡化及服饰审美观念的变化等。因此,羌族剪纸传承和发展需注意处理好传承与传播、活态与活用、变与不变等关系。  相似文献

为提高SLS成型系统堆积方向微细结构的制作质量,以过度烧结深度、烧结密度和Z向尺寸偏差为优化指标,采用多指标的正交试验设计方法,通过极差分析法,讨论激光功率、预热温度、激光扫描速度、分层厚度等成型工艺参数对试件质量的影响,利用综合平衡法确定了最优工艺参数组合。试验结果表明:激光功率选取16 W,预热温度选取98℃,激光扫描速度选取3 m/s,分层厚度选取0.15 mm时,试件的制作质量为最优。试验结果有助于SLS快速成型系统提高堆积方向微细结构的制作质量。  相似文献

The depths, which have been used to detect outliers or to extract a representative subset, can be applied to classification. We propose a resampling-based classification method based on the fact that resampling techniques yield a consistent estimator of the distribution of a statistic. The performance of this method was evaluated with eight contaminated models in terms of Correct Classification Rates (CCRs), and the results were compared with other known methods. The proposed method consistently showed higher average CCRs and 4% higher CCR at the maximum compared to other methods. In addition, this method was applied to Berkeley data. The average CCRs were between 0.79 and 0.85.  相似文献

This paper investigates the determinants of countries’ choices of monetary policy framework. A brief narrative focused on groupings of countries motivates an econometric analysis which draws on previous work on the determinants of exchange rate regimes, bringing in standard factors as well as the trade networks of potential anchor currency blocs and the financial market depth that are emphasised in the narrative. The model turns out to be able to predict three quarters of countries’ choices, and there is no obvious systematic pattern in the errors. The results have important implications for how countries should choose their monetary policy frameworks.  相似文献

Female genital cutting (FGC) is a persistent social norm in the Liben district of southern Ethiopia. This study explores whether the sexual experiences of married men and women differ by women's FGC status. Qualitative in-depth interviews were conducted with 28 women with different types of FGC (or no FGC) and 21 husbands. Compared to others, women with more severe FGC reported traumatic sexual experiences and decreased sexual desire. Nonetheless, participants largely endorsed FGC for daughters, revealing pressure to maintain the practice. Opportunities for change exist, as women and men recognized the sexual pleasure and healthy birth experiences of uncut women.  相似文献

The smoothness of Tukey depth contours is a regularity condition often encountered in asymptotic theory, among others. This condition ensures that the Tukey depth fully characterizes the underlying multivariate probability distribution. In this paper we demonstrate that this regularity condition is rarely satisfied. It is shown that even well-behaved probability distributions with symmetrical, smooth and (strictly) quasi-concave densities may have non-smooth Tukey depth contours, and that the smoothness behaviour of depth contours is fairly unpredictable.  相似文献

服饰图案切割路径规划是服饰图案自动切割技术的关键部分之一。文中用改进的离散人工蜂群算法实现了激 光切割系统对异形满版服饰图案的切割工艺路径规划优化。首先,把满版服饰图案激光切割路径规划转化为广义旅行 商问题求解,证明了路径规划转化成普通TSP问题比转化成第一类广义TSP问题更为有效,并给出了路径规划中“图案 始切割点”的优化选择方法。然后结合部分匹配交叉和启发式变异搜索方法的人工蜂群算法求解TSP问题,证明了与 A*算法及遗传算法相比,该方法更为优越。并且该方法已应用于激光切割机切割异形满版服饰图案路径规划的生产实 践,运行可靠,比未规划时的工艺路线平均提高效率33.7%。该方法提供了一种解决TSP问题的新方法,具有一定的理 论意义和价值  相似文献
