It is difficult to find indicators for measuring the achievement of objectives during the progress of project portfolios. This article presents an approach for developing key strategic perfor‐mance indicators considering this limitation. The indicators proposed help measure the achievement of a portfolio's strategic objectives taking into account the realization of key benefits. This approach helps identify strategic interdependences between projects that the portfolio is composed of, facilitating the understanding of how the performance of a single project affects the overall performance of a portfolio. The key perfor‐mance indicators can also be used for monitoring the materialization of risks and opportunities influencing the strategic performance of a portfolio.  相似文献

The global financial and economic crisis has prompted some scholars to suggest that a fundamental regulatory shift away from neoliberalism will take place – both in general and in the field of EU competition regulation. This paper shows that so far no radical break with the neoliberal type of competition regulation is heaving into sight. It sets out to explain this from the vantage point of a critical political economy perspective, which identifies the circumstances under which a crisis can result in a regulatory paradigm shift. Contrasting the current situation with the shift in EC/EU competition regulation after the crisis in the 1970s, the paper argues that the preconditions for a fundamental shift in this issue area are not present this time around. Several reasons account for this: the current crisis has been construed by economic and political elites as a crisis within and not of neoliberal capitalism; the social power configuration underpinning the neoliberal order remains unaltered; no clear counter-project has surfaced; the European Commission has been (and remains) in a position to oppose radical changes; and finally, there are no signs of a wider paradigm shift in the EU's regulatory architecture.  相似文献

文章提出了一种可以描述故障后系统稳定程度的灵敏度指标,根据系统稳定性逐渐恶化指标趋于零的特点,计算了系统部分参数的临界值;根据稳定指标与故障切除时间在一定范围内的良好线性关系,估算了系统故障临界切除时间;并在单机无穷大系统与10机典型新英格兰系统下进行验证,证明了该方法的正确性。  相似文献

Group Support Systems may be “distributed”; for nonsimultaneous use by being embedded in a Computer‐Mediated Communication System (CMCS). In this manner, large groups may use them for complex tasks over an extended period of time. Will executives use such systems, and what are their reactions? This case study of elites engaged in formulating recommendations for the White House Conference on Productivity demonstrates that executives can use such systems, given that “critical success factors”; are met. Perceived information richness is strongly correlated with perceptions of productivity enhancement as a result of system use.  相似文献

This paper explores the effect of time‐varying velocity on output responses to policies for reducing/stopping inflation. We study a dynamic general equilibrium model with sticky prices in which we introduce time‐varying velocity. Specifically, we endogenize time‐varying velocity into the model developed by Ireland (1997) for analyzing optimal disinflation. The nonlinear solution method reveals that, depending on velocity, the “disinflationary boom” found by Ball (1994) may disappear even under perfect credibility and that early output losses may be much larger than previously thought. Indeed, we find that a gradual disinflation from a low inflation may even be undesirable.  相似文献

Drawing on and contributing to materialist state theory, the regulation approach and institutional economics for more than three decades, Bob Jessop can certainly be considered one of the foremost Marxist political economists of our time. Recently, he has taken on board the cultural turn in social analysis by developing a highly original cultural political economy of the knowledge-based economy. As a contribution to the further development of a cultural political economy that is sensitive to the cultural dimensions of social life while retaining an emphasis on capital accumulation and state regulation, this article directs attention to the limits of Jessop's approach and suggests possible amendments to the theory. In particular, the article highlights the need to move beyond a concern with regulation towards a cultural political economy of complexity and emergence.  相似文献

This article considers processes of urban development within the context of mega‐event preparations in Rio de Janeiro. We begin with a brief overview of these development processes, highlighting their connections to political and economic change in recent years. Proponents of these mega‐event‐led initiatives argue that Rio is undergoing a period of inclusive growth and integration: a perspective we call here a ‘post‐Third‐World city' narrative of urban renewal. Critics, however, contend that urban officials are harnessing mega‐events (e.g. the 2014 World Cup and the 2016 Olympic Games) to push forward a neoliberal agenda of socially unjust policies benefiting the interests of capital and marginalizing the city's poor and especially its favelas (i.e. the ‘city‐of‐exception' thesis). In this article we explore the insights of these two perspectives and consider why they have grown popular in recent years. Though we side generally with the city‐of‐exception thesis, we argue that important geographic and historical particularities must also be accounted for. Without carefully situating analytical perspectives empirically—in particular, cases in which theoretical models are drawn from European and North American contexts—urban researchers risk concealing more than they reveal in analyses of rapidly developing countries like Brazil.  相似文献

某角速度传感器的输入与输出成近似线性关系,测量输出的电压值即可得到目标运动的角速度。为了提高测量的精度,通过对角速度传感器零位和灵敏度的误差进行校正,可得到更为精确的目标运动角速度。实验表明,该校正方法能有效提高角速度传感器的测量精度,有一定的实用性。  相似文献
