For a new leader, the process of entering and establishing a position of leadership in a complex organization presents a major challenge. This challenge seems particularly acute when authority, goals and technology are ambiguous, as in many professional service organizations. In this paper, we integrate ideas from the literature on socialization and role theory as well as that on executive succession processes to view new leader integration as a mutual adjustment process between two trajectories – that of the organization and that of the new leader. It is argued that this may lead to four possible types of integration outcomes: assimilation, transformation, accommodation and parallelism. Drawing on a case study of a large hospital, the paper identifies several mechanisms that can be mobilized by the new leader to enhance his or her room for manœuvre as the integration process evolves. The mechanisms can be classified as collaborative or affirmative, with each type having different risks and advantages. The case analysis further reveals that leader integration processes may be differentiated between different activity domains, dynamic over time (as the use of one type of integration approach alters the potential for another later), and interactive across different activity domains (as events in one part of the organization have consequences for those occurring in another).  相似文献

Most recent empirical analyses of production in the sports economic literature have focused on Major League Baseball. This paper extends that literature by analysing football production in the National Football League (NFL). Using the Poisson regression model, we measure the performance of NFL teams and head coaches. The measure is based on a production process where player skills are converted into games won. The evidence reveals that quality coaching is an important component in the production process. It appears that efficient coaching can account for an additional three to four victories in a given season. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

Technical networks (transport, telecommunications, energy etc.) possess paradoxical virtues. They produce ‘structuring effects’ on space, obtaining comparative advantages for the places they serve. But they are ubiquitous factors which also enable a homogenization of space. The myths of deterritorialization and dual space are refuted by empirical analyses of the interaction between networks and territories. Networks ‘format’ market areas and political territories. They create matrixes which until now were controlled by the public powers. Linked to current transformations – globalization, deregulation – the present mode of development of the technical macro‐systems brings about a telescoping of geographical scales which is having an adverse effect on the historic compromise between networks and territories. The boundaries of traditional political space have become obsolete and an economic rationale in the form of an extension of the technical networks predominates. In order to rediscover their policy‐making capacity, local authorities must pay more attention to controlling the occupation of public space as well as to the design and organization of the networks’ hubs. They should encourage the emergence of users as players in the regulation of public utilities so that debates on universal service and territorial equality may be activated. Les réseaux techniques (transport, télécommunication, énergie etc.) sont parés de vertus paradoxales. Ils produiraient des ‘effets structurants’ sur l’espace, procurant des avantages comparatifs aux lieux desservis. Mais, facteurs d’ubiquité, ils permettraient aussi une homogénéisation de l’espace. Ces mythes de la déterritorialisation et de la dualisation de l’espace sont réfutés par les analyses empiriques des interactions entre réseaux et territoires. Les réseaux ‘formatent’ des aires de marché et des territoires politiques; ils fabriquent des métriques, dont les pouvoirs publics avaient jusquà présent la maîtrise. Liées aux transformations en cours – globalisation, dérégulation – le mode de développement actuel des macro‐systèmes techniques entraîne un télescopage des échelles géographiques qui met à mal le compromis historique entre réseaux et territoires. Il y a obsolescence des frontières des espaces politiques traditionnels et prédominance de la logique économique dans l’extension des réseaux techniques. Afin de retrouver des capacités d’action, les collectivités locales doivent porter plus d’attention au contrôle de l’occupation de l’espace public ainsi qu’à la conception et à l’organisation des noeuds de réseau. Elles ont aussi à favoriser l’émergence des usagers comme acteurs de la régulation des services en réseau, afin que soient activés les débats sur le service universel et sur l’équité territoriale.  相似文献

Abstract.  This survey presents the set of methods available in the literature on selection bias correction, when selection is specified as a multinomial logit model. It contrasts the underlying assumptions made by the different methods and shows results from a set of Monte Carlo experiments. We find that, in many cases, the approach initiated by Dubin and MacFadden (1984) as well as the semi-parametric alternative recently proposed by Dahl (2002) are to be preferred to the most commonly used Lee (1983) method. We also find that a restriction imposed in the original Dubin and MacFadden paper can be waived to achieve more robust estimators. Monte Carlo experiments also show that selection bias correction based on the multinomial logit model can provide fairly good correction for the outcome equation, even when the IIA hypothesis is violated.  相似文献

The changing legal landscape of the right of the employer to control and monitor employee behavior is examined. Two distinct areas are defined: behavioral monitoring and behavioral restrictions. Relevant statutory laws and the developing common law are discussed. We also examine potential employee reactions to such policies by evaluating the reactions of graduate students to six employer policies including weight restrictions, grooming requirements, use of GPS locators, drug testing, ban on off-duty smoking, and email and internet monitoring. Students responded to these policies by determining the reasonable interest of the employer in the behaviors being monitored or controlled and the manner in which policies were implemented. Their comments suggest that employees may accept some level of monitoring or behavioral restrictions if the employer can make a convincing social account of the need for a policy. Additionally, the policy must be clearly communicated and properly implemented. However, restrictions on off-duty behavior were typically poorly received with the exception of illegal drug use.  相似文献

We study the effect of environmental regulation (taxation) on emissions when the only available abatement method consists of product-mix changes. Firms choose to produce one or both varieties of a product—a pollution-intensive (dirty) and a non-pollution-intensive (green)—and compete in a differentiated Cournot duopoly. We characterize the equilibrium market structure as a function of the tax rate and show that increases in the tax can promote product-mix changes that lead to a jump in emissions for some tax range, an effect we call the perverse effect of taxation. Our work emphasizes the key role horizontal product differentiation in this process and shows that the perverse effect does not require the presence of vertical product differentiation. Further, the perverse effect of taxation is especially strong in the presence of incomplete regulation, that is, when only one of the markets is subject to taxation.  相似文献

Recent evidence shows that there is great heterogeneity in the price setting frequency across sectors, and that those changing prices frequently do so even under low inflation. What happens to price setting strategies of sticky price goods under moderate inflation? We built a dataset of monthly newspaper and magazine prices for Colombia, for the period 1960–2005, an exceptional example of prolonged moderate inflation. Within this macroeconomic scenario, and the novel database, we study the frequency of price adjustment, the relative importance of time- and state-dependent theories, and their evolution as inflation declined from moderate rates to single digits.  相似文献
