The immediate motivation of this paper is California Bill AB 394, legislation which mandates fixed nurse-to-patient staffing ratios as a means to address the current crisis in the quality of health care delivery. Modeling medical units as closed queueing systems, we seek to determine whether or not ratio policies are effective at managing nurse workload. Our many-server asymptotic results suggest that ratio policies cannot provide consistently high service quality across medical units of different sizes. As a remedy, we recommend policies that deviate from the restrictive linear nature of ratio policies, employing the 'square root rule' commonly used to staff large service systems. Under some quality of care assumptions, our policies exhibit a type of 'super' pooling effect, in which, for large systems, the requisite workforce is significantly smaller than the nominal patient load.

In all the literature on the theory and practice of negotiation, the governing metaphor remains consistently one of war or fighting. This is true not only for tactical schools of power-based negotiation, but even for more constructive, interest-based approaches. Our language is infused with talk of tactics, flanks, concessions, gaining ground and winning. This article explores the possible consequences of abandoning this picture in favor of the far too little explored metaphor of the dance. We will see that both the content and the process of negotiation can change dramatically once when we think of bargaining as an aesthetic activity which provides intrinsic joy as well as extrinsic benefits. In such a dance, there is plenty of room for competition as well as cooperation, as movements can be spirited and confrontational as well as smooth and harmonious. We identify many forms of dance in negotiation, and explore three: the dance of positioning, where passions and presentations interact proudly; the dance of empathy, when the partners come to better understand each other; and then the dance of concessions, where the deal is struck and the music comes to an end. Finally, we will try to show how the dance can be employed pedagogically, in teaching and training negotiation and mediation. In particular, the Brazilian dance of capoeira illustrates holistically and experientially how movement and rhythm can be interpreted both as fight and as a dance and how we can come to see a process as both aesthetic and purposeful at the same time. First feeling, then thinking and finally speaking, we can use this medium to explore the dynamics of confrontation and cooperation in a negotiation setting.

How do firms cope with the challenges of disruptive change in their industry? Numerous studies have highlighted that success with any prior technology creates a negative legacy effect for the next radical technological shift. We question the overly pessimistic view of such legacy effects and ask how quickly firms embrace echnological breakthroughs by radically innovating and who wins in the longer term? In this paper, we argue that legacy is a multi-faceted construct whose diverse aspects could simultaneously have different effects on innovation speed and market performance. We identify three main types of legacy related to echnology, organizational, and country-level influences. Previous research tends to focus on technological or market effects in isolation, whereas we seek to study the effects of both firm and country legacy simultaneously on speed to radical innovation and market performance over time. Based on a conceptual framework we develop six hypotheses concerning the legacy effects on initial speed radical innovation and subsequent market performance. We chose the European retail banking industry and the focal innovation of transactional Internet banking as a suitable empirical context to employ quantitative hypothesis testing. Detailed and longitudinal (1996-2001) data were collected for a sample of 123 banks from six European countries: United Kingdom, Germany, France, Sweden, Finland, and Denmark. We specified a model and used threestage least squares (3SLS) as a method to estimate simultaneous regression equations due to endogeneity of a key variable. We show that the prevailing negative view of legacies is likely to be overstated.

In this paper we examine the role of disruptive or upsetting events in people's professional lives and explore how they influence individuals' investments in their careers. Based on previous research we have assumed that due to considerable societal and economic changes in Russia and the reported negative consequences felt by many individuals, the context of that country is a fruitful arena for an investigation of the role of upsetting events on individuals' careers. At the same time, despite the negative events and a disruption of many traditional career-supporting structures, a significant number of Russians managed to reinvent their careers and achieve tremendous objective and subjective success in their careers in a relatively short time period.

This paper examines stories about career investments of 140 successful entrepreneurs from Russia. A significant portion of these people explicitly reported influence of upsetting events on their own career investments. Based on the exploration of career stories, the paper introduced a typology of the upsetting events in the Russian context. The events were generally classified into those that represented "macro" and "micro" upsetting events. Macro events refer to changes in socio-economic, and political systems. Micro events refer to the events that only concern the individual him- or herself, or may include events at work or at home. Our analysis of the career investments of the Russian entrepreneurs using the intelligent career concept shows that when faced with the upsetting events individuals tend to (a) reconsider their existing events, (b) divest from their old ways of knowing, and (c) invest in relatively new ways of knowing.

Our study calls a particular attention to the role of career divestments, or discontinuing certain ways of investing in order free resources for a different investment expected to be more fruitful in terms or returns. Attention to divestment may be warranted due to the increased unpredictability of working lives of today's career actors.

This study contributes to responding to a call for a better understanding of the role of upsetting events on people's careers and the society at large. We also bring further our understanding of human adjustment to the sometimes upsetting changes in their surroundings through working life, thus enhancing our understanding of the role of careers in socio-economic systems. Last but not least, the study also contributes to a better understanding of careers in modern Russia. With the increasing role of Russia on the international political and economic arena, understanding people through looking at their working lives is a good start for multiple potential research endeavors in the fields of career research and beyond.

This paper investigates situations where a sizable sub-set of consumers prefer an inferior (dominated) offer made by an established brand to a superior (dominating) offer made by a less-established brand. Established brands are those for which consumers hold more confident beliefs concerning overall quality. Through a series of eight experiments, we test the hypothesis that the preference for a dominated established brand is linked to ambiguity aversion, a seemingly unrelated pattern of choice behavior between monetary gambles. We first show a correlation between ambiguity aversion and the preference for dominated established brands. We then demonstrate that the preference for established brands is enhanced when ambiguity aversion is made more salient in unrelated preceding choices. To further study the ambiguity-reducing properties of established brands, the last experiments assign brand names to monetary gambles, and it appears that (a priori unrelated) established brand names increase the likelihood of choosing ambiguous gambles. Overall, this research argues that brand equity for longstanding brands derives (at least in part) from consumers' tendency to avoid ambiguity.

Cross-country or cross-industry studies of technology diffusion typically estimate how independent factors affect diffusion speed or timing, often based on a two-stage approach. In many applications, however, countries (industries) differ most in the saturation level of diffusion. In a novel, single-stage econometric approach to a standard diffusion model, we therefore estimate how the saturation level co-varies with independent factors. In our application to diffusion of an important retail information technology, we focus on the competitive effect of hypermarkets (superstores). We also find standard scale, income and labor substitution effects.

This working paper explores the challenges of accelerated development of organizational talent. The meaning of the word 'accelerated' is that such development takes place at a pace that is significantly higher than that of 'traditional' development that allows an individual to learn the intricacies of the current job, observe incumbents in a higher level position (usually, one level up), practice elements of the boss' job when being delegated tasks, undergoing formal training, or benefiting from the knowledge accumulated by others and codified in the knowledge management systems. Accelerated development means, contrary to the usual, more traditional developmental path, bypassing traditionally expected career steps, stretched over a longer period of time learning opportunities, and/or age-related developmental progression. Accelerated development is a necessity for organizations facing unprecedented growth, lack of qualified individuals in the internal or external labor markets, and significant pressures from other organizations that are ready to 'poach' talented executives and employees and offer them even higher levels of responsibility and remuneration. Organizations also respond with accelerated development initiatives to the individuals engaged in career entrepreneurship, i.e., those who make alternative career investments in order to enjoy quicker returns in terms of career growth and progression.
