Strategizing through analyzing and influencing the network horizon   总被引:2,自引:0,他引:2  
How does a firm keep on being valuable in a network? One requirement is that the firm has a sufficient overview of the network and its dynamics. In other words, a firm's strategy depends on the firm's overview of the network—its network horizon. How comprehensive or limited should its network horizon be? Is it necessary to know the network beyond the direct counterparts? Such issues have not received much attention. In this article, we discuss network horizons and argue that limited network horizons are both inevitable and useful. However, such myopia requires that a firm's counterparts effectively and efficiently mediate between the firm and the rest of the network. Based on a case study, we introduce and discuss three mediating functions of counterparts: a joining, a relating, and an insulating function, and we claim that in order to support a firm's strategizing, managers need to analyze and influence counterparts' mediating functions and thereby the firm's network horizon.  相似文献

Predicting the geo-temporal variations of crime and disorder   总被引:2,自引:0,他引:2  
Traditional police boundaries—precincts, patrol districts, etc.—often fail to reflect the true distribution of criminal activity and thus do little to assist in the optimal allocation of police resources. This paper introduces methods for crime incident forecasting by focusing upon geographical areas of concern that transcend traditional policing boundaries. The computerised procedure utilises a geographical crime incidence-scanning algorithm to identify clusters with relatively high levels of crime (hot spots). These clusters provide sufficient data for training artificial neural networks (ANNs) capable of modelling trends within them. The approach to ANN specification and estimation is enhanced by application of a novel and noteworthy approach, the Gamma test (GT).  相似文献

WORLD OUTLOOK     
Events in the Gulf have finally brought an end to the world economic boom of the last eight years. The oil price shock itself is only partly responsible for the downturn. The previous tightening of monetary policy in the face of inflationary pressures and the end of a rapid period of credit and asset price expansion had severely weakened the ability of some economies to respond to the shock. This is reflected in the diversity of response, most obviously in the United States where Fed fine tuning and the credit crunch have already weakened the economy. The rise in oil prices has led to a sudden collapse in consumer confidence and a swift cutback in output. Although we do not expect the recession to be deep, the financial problems will delay recovery. The Japanese economy was already in financial difficulties before the shock, although the real economy was stronger and here we expect a sharp deceleration from almost 6 per cent growth last year to around 3.5 per cent. In contrast the German economy, partly shielded by the substantial appreciation of the DM over the last year, has been affected less by the oil price shock and we expect the consumer and investment boom to continue this year as the economies merge. This provides a welcome boost to other European economies.  相似文献

This paper uncovers an increasing proportion of quoted UK companies omitting cash dividends. Using a large panel of quoted UK firms, we estimate panel data probit models for the incidence of dividend omissions and cuts as functions of financial characteristics including cash flow, leverage, investment opportunities, investment and company size. These variables account for most of the increase in omission since 1995. There is relatively little evidence to link this to the major tax reform of 1997 that abolished tax refunds on dividend income payable to tax‐exempt institutions. Significant persistence effects indicate companies are slow to adjust their balance sheets through their dividend.  相似文献

ABSTRACT   This paper critically explores the common distinction made between words and deeds (or ideas and techniques) in the diffusion of management knowledge literature. The concern with whether management ideas are really being implemented in an organizational context intuitively points to the possibility of a contrast between simply talking about a practice or 'hype' and practical implementation. Drawing on empirical research on the diffusion of customer service culture in two call centres where 'verbal labour' predominates, it is argued that this distinction is important, but overdrawn. Eschewing discursive reductionism, the concepts of 'talk in work' and 'talk about work' are developed to illustrate how talk can be a technique of implementation in its own right.  相似文献

passive drinking     
The threat to health from passive smoking is now well understood. Andrew Wilson, a freelance healthcare journalist, reveals the alarming results of recent research into ‘passive drinking’. Without wishing to cause alarm Economic Affairs wonders how seriously we should treat these new findings?  相似文献

Insights from the resource dependence approach, dynamic fit, and strategic choice theories are used to explore the strategies adopted by Chinese enterprises, their settings, and the relationship between strategy, environment, and performance. Results from 959 firms indicate that respondents operating under ‘more marketized’ institutional settings tend to locate themselves in more munificent environments and place greater emphasis on meeting customer needs. Firms in China do not trade off one strategic direction against another, and certain strategy/environment coalignments have significant implications for performance. In particular, performance is better in more marketized and munificent environments and amongst firms who adopt an ‘aggressive’ strategic posture. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

This article examines the puzzle of why futures prices continue to react to USDA crop reports despite the fact that reports appear to be no longer "newsworthy," that is, provide no better production estimates than private forecasts. The information value of reports is measured in terms of their influence on rational agents' harvest-time corn price expectations, which are uncovered using a Hamilton-type modeling approach. Results show that reports are still "newsworthy," as they would contribute to agents' price expectations if released a day early. Thus futures price reactions, which closely reflect price expectations, are rational and consistent with efficient markets hypothesis.  相似文献
