  • Whereas the selection of segmentation variables mainly drawn from management needs is straightforward, the selection of variables used as descriptors of the identified segments is more complex. This complexity stems not only from the enormous num- ber of possible variables, but also from the necessary twofold link these variables have to offer, namely the link with the selected segmentation variables on the one hand, and the link with secondary data on media profiles, distributional coverage etc.

  • The asynchrony, heterogeneity, and inherent loose coupling that characterize applications in a wide-area network promote event interaction as a natural design abstraction for a growing class of software systems. An emerging build- ing block for such systems is an infrastructure called an event notification ser- vice [Rosenblum and Wolf 1997]. We envision a ubiquitous event notification service accessible fromevery site on a wide-area network and suitable for supporting highly distributed appli- cations requiring component interactions ranging in granularity from fine to coarse.

  • Many more women are active today compared to when the first studies of activity in America were conducted. However, as a group, girls and women are still less active than boys and men. Some of this difference in activity between males and females can be explained by the historical disparity in opportunities for females. Since 1972, when Title IX was implemented, more females have become involved in organized sport. We have yet to discover the effects of this increased participation on lifetime activity among females....

  • From the perspective of behavioral economics, rationality is bounded by asymmetrical preferences. Consider, for example, status quo bias. Samuelson and Zeckhauser (1988) reported that when Harvard University changed some of the health insurance options it offered employees, newly hired personnel were more likely to enroll than were people already on the university’s payroll; those employees generally chose to keep their current plans. The appeal of the status quo can be explained, in part, by the concept of loss aversion.

  • Though it is widely recognized that the population of the United States is aging, much of our current understanding in the field of individual decision making is based on data from student populations. While this could be a consequence of subject availability, it may reflect a common though largely unsubstantiated belief that decision making ability declines with aging (Peters 2000). Many older individuals are productive and intellectually viable throughout their lives. Still, others are vulnerable to dementia and neurodegenerative illnesses, such as Alzheimer's disease.

  • The benefits of nonemergency fund operations are the services that come out of the infrastructure they build, not the income generated during construction for carpenters and bricklayers. In evaluating fund projects, the value added as a result of the extra services coming from the project should be considered. This distinction is relevant for projects that upgrade or replace infrastructure, as op- posed to those that build new infrastructure.

  • The Table below organizes known bad bank examples and current proposals according to the source of capitalization and organizational form. As the Table shows, the majority of known bad banks have been established based on a decentralized organizational model. Retriva and Securum (Sweden) as well as BIH (Berlin) were founded through the subdivision of a bank threatened with insolvency into a good and bad bank. In all three of these cases, the government provided the funding for the bad bank and also recapitalized the good bank in exchange for a shareholder stake. ...

  • We have consistently found that in order to gain lasting commitment to the sales training process, we must recognize that people are different and they need the flexibility to incorporate what they already know with the new ideas we bring; this is the only way to get sincere and lasting buy-in and ownership. Beyond a base level of common program methodology and standards, we work privately with each participant to custom-tailor a plan that works with their unique personality, style and comfort level.

  • This report evaluates the responses of the United Nations to the questions of human cloning governance. The difference between reproductive human cloning and using of cloning technology for research is explained followed by an ethical analysis of cloning. Discussion of ethics at the UN level often brings to mind the notion of deep, profound, commonly held principles to guide human actions. While general ethical principles, such as the principle of doing no harm in medical practice, are widely respected, the question of what amounts to harm is less easily defi ned.

  • The macroeconomic configuration at the present time is conducive to sizeable interest rate exposures in the financial industry. Because virtually all firms are tempted to take the same risks (“herding”), there is also a very important systemic dimension. All firms will not be able to get out when expectations of future rates change – leading to “overshooting” in market interest rates or even illiquidity in interest rate hedging markets.

  • Weblogs and message boards provide online forums for discussion that record the voice of the public. Woven into this mass of discussion is a wide range of opinion and commentary about consumer products. This presents an opportunity for companies to understand and respond to the consumer by analyzing this unsolicited feedback. Given the volume, format and content of the data, the appropriate approach to understand this data is to use large-scale web and text data mining technologies.

  • To support replication, each spanserver implements a single Paxos state machine on top of each tablet. (An early Spanner incarnation supported multiple Paxos state machines per tablet, which allowed for more flexible replication configurations. The complexity of that de- sign led us to abandon it.) Each state machine stores its metadata and log in its corresponding tablet. Our Paxos implementation supports long-lived leaders with time-based leader leases, whose length defaults to 10 seconds.

  • Some organizations may use outside consultants to collect information or review executive performance. Keep in mind that evaluating the executive is like running an EKG on the heart of the organization: you will not get any closer to the pulse of the organization. If you use an external service, it should be as a contributing part of the overall effort. And, whether the in-person evaluation is presented by a com- mittee, a board officer, or the entire board, the final evaluation must be the voice of the entire board. It is only as a single entity that the board has any...
