Using a sample of over 5000 establishments in Germany, we analyze the antecedents and effects of profit sharing (PS) and employee share ownership (ESO) with respect to the ability of firms to meet their recruitment and retention objectives and to achieve employment growth. We draw on both economic and behavioral perspectives to argue that firms that adopt PS and ESO plans do so in order to attract and retain employees. Using logistic regression and a propensity score matching technique, we find that firms that face higher recruitment problems, and those that have greater employment growth objectives, are more likely to use ESO and PS. Unlike ESO, PS enhances firm-level employment growth. However, neither ESO nor PS help firms to fully resolve recruitment and retention problems. 相似文献

“信号与系统”和“数字信号处理”优化整合的实践与探索 总被引:1,自引:0,他引:1
《价值工程》2013,(3):171-172
近年来,随着信息技术的迅速发展及超大规模集成电路和计算机的普遍应用,新的信号处理和分析技术不断涌现。有关信号与系统和数字信号处理的概念、理论和分析方法不断发展,使用领域也不断扩大。鉴于信息类专业两大核心课程《信号与线性系统》和《数字信号处理》知识结构和教学内容存在的问题,针对当前三类本科院校学生的特点,提出了构建新的教学体系,优化整合教学内容,并对相关课程进行了实践及探索。以教学内容,教学方式,实验教学,考核方式等为主体思路,进行两课的优化整合。 相似文献

本文运用三时期参数变结构协整方法,着重研究我国进出口对经济增长的间接作用,以及产生间接作用的介体与路径。协整结果发现,大多数考察变量与进出口之间存在显著的参数变结构现象。实证研究得出,进出口通过投资、人力资本、技术进步、消费与经济结构这些介体对经济增长的间接作用有正有负,而加总效应都是正值,出口间接作用的弹性测算值较大,而进口间接作用的弹性测算值较小。 相似文献

Institutional, or sector-by-sector input–output tables have traditionally been used in regional and interregional modelling. This paper examines the origins of this tradition and argues instead, both theoretically and empirically, for the integration of make and use submodels within models of production, demand and interregional trade, outlining the manner in which they can be integrated. Further, it is argued that structural rather than reduced-form models represent a sounder theoretical base. Finally, a Danish interregional model (LINE) based on a social accounting matrix framework that employs these principles is presented. The paper also deals with the issue of data construction at the regional and interregional levels, based on the make and use approach. It is argued that when data are constructed at a low level of sectoral and spatial aggregation under accounting consistency constraints, data quality and validity are high. 相似文献

This paper examines British and Irish work-related values and attitudes. It is set in the context of the importance of eliciting high work commitment and effort from employees as a necessary condition for enhanced competitive performance. More specifically it seeks to establish if British and Irish work values and attitudes conform to what we would expect from Hofstede's indices. On the basis of the original international research presented here, Hofstede's indices are found not to be very reliable predictors of work values and attitudes in Great Britain and the Republic of Ireland. The results suggest that work effort is associated with different values in these two countries. 相似文献
