In the present study, we investigated the relationship between perceived constructiveness and perceived immediacy and frequency of supervisor performance feedback and work performance. In two pilot studies, we obtained support for the two‐dimensionality of our measure of supervisor performance feedback. In the main study, perceived constructiveness of supervisor performance feedback and work performance was positively related when perceived immediacy and frequency of supervisor performance feedback was high. We discuss theoretical and practical implications and directions for future research. © 2016 Wiley Periodicals, Inc.  相似文献

2003年以后,农村土地纠纷取代税费争议成为农民维权抗争的焦点,失地农民群体不仅经济利益遭受损失,社会利益也处于边缘化状态[1]。文章基于54封失地农民的来信,试图通过对基础资料的分析,归类失地农民维权途径与反馈结果,展示失地农民诉求受阻的具体环节,呈现失地农民维权途径与反馈机制的运行机理,以期化解农民的利益表达机制梗阻。  相似文献

We consider a policy game between a high-income country hosting a drug innovator and a low-income country hosting a drug imitator. The low-income country chooses whether to enforce an International Patent Regime (strict IPR) or not (weak IPR), and the high-income country chooses whether to allow parallel imports (PI) of on-patent drugs or market-based discrimination (MBD). We show that, for a moderately high imitation cost, both (strict IPR, PI) and (weak IPR, MBD) emerge as the subgame prfect Nash equilibrium (SPNE) policy choices. For relatively smaller imitation costs, (weak IPR, MBD) is the unique SPNE policy choice. The welfare properties reveal that although innovation may be higher at the (strict IPR, PI) policy regime, the market coverage and national welfare of the low-income country, and the total welfare are all lower. This opens up the efficiency issue of implementing TRIPS and at the same time allowing international exhaustion of patent rights.  相似文献

在正交频分复用(OFDM)系统中,定时误差、多普勒效应以及本地振荡器不稳定等因素都会引起估计频率产生偏移,致使子载波星座相位发生旋转,并随着时间而不断累积,最终导致解调失效。为此,提出了用均方误差短时反馈算法来矫正旋转相位的新方法。该方法利用在反馈时间段内计算得出的残余相偏来直接矫正后续接收数据的相位。仿真结果表明,该算法很好地满足实时跟踪的要求,具有运算简单、速度快等特点,同时也提高了系统的性能。  相似文献

Abstract

As Ireland has followed other countries in modernizing its public sector according to the principles of ‘new public management’ (without introducing market mechanisms on the same scale as its Anglo-Saxon counterparts), the capacity of its public managers to supply the leadership required to drive this programme forward has been identified as a crucial factor affecting its sustainability. A broadly representative sample of Irish public managers has been surveyed using the Leadership Effectiveness Analysis diagnostic instrument to identify those behaviours that need to be developed since they are infrequently used or can moderate the liabilities associated with frequently used behaviours. The findings of this study are interpreted within the context of a broader literature that debates the distinctiveness, significance and malleability of organizational leadership, in general, and the possibility of achieving a balance between different and, at times, conflicting public leadership behaviours, in particular.  相似文献

The dynamic links between stock market indices are analyzed in a GARCH-M framework, using daily data from France, Germany, Italy and the USA. It is shown that indices in the periods before and after the introduction of the Euro as a single currency display a very distinct behaviour. Consistent with the literature, in the earlier period price changes are found to have an impact the next day on other markets. In the latter period this type of co-movement disappeared within Europe. Feedback trading has been shown to induce (negative) autocorrelation in national stock markets. In this paper an international version of the feedback trading model is used to illustrate that the lead–lag relationships across countries and the strength of these links depend on the currency regime.  相似文献
