Whilst much research has been conducted on decision support for electronic negotiations and some research has been done on communication support in this area, there is a lack of research on the interplay between these two elements of negotiations. The questions whether both are equally important, whether one effects the other, or whether they show counter-effects are important both for negotiation training (i.e. what should be the focus for becoming a good negotiator) and for system research (i.e. which system support elements need to be developed). The current paper presents results of a controlled laboratory experiment with negotiators that were provided with decision support and communication support and negotiators that had only communication support available. The impact of decision support on the communication process and on outcome dimensions as well as the impact of communication behaviour on the negotiation process and the qualitative dimensions of the outcome will be discussed. 相似文献

Immigrant earnings: age at immigration matters 总被引:5,自引:1,他引:4
A correlation between age at immigration and earnings is observed in Canadian census data. The evidence supports three underlying sources of the effect; first, work experience in the source country yields virtually no return in the host country; second, the return to education varies with age at immigration, and, finally, an 'acculturation' effect is observed for immigrants who are visible minorities or whose mother tongue is not English. Further, it is found that educational attainment, and relatedly earnings, vary systematically across age at immigration with those arriving around age 15 to 18 obtaining fewer years of education.

We implement a controlled, multi-site experiment to develop and test guidance principles for benefits transfers. These argue that when transferring across relatively similar sites, simple mean value transfers are to be preferred but that when sites are relatively dissimilar then value function transfers will yield lower errors. The paper also provides guidance on the appropriate specification of transferable value functions arguing that these should be developed from theoretical rather than ad-hoc statistical approaches. These principles are tested via a common format valuation study of water quality improvements across five countries. While this provides an idealised tested, results support the above principles and suggest directions for future transfer studies. 相似文献

The making of statistical inferences in distributional form is conceptionally complicated because the epistemic 'probabilities' assigned are mixtures of fact and fiction. In this respect they are essentially different from 'physical' or 'frequency-theoretic' probabilities. The distributional form is so attractive and useful, however, that it should be pursued. Our approach is In line with Walds theory of statistical decision functions and with Lehmann's books about hypothesis testing and point estimation: loss functions are defined, risk functions are studied, unbiasedness and equivariance restrictions are made, etc. A central theme is that the loss function should be 'proper'. This fundamental concept has been explored by meteorologists, psychometrists, Bayesian statisticians, and others. The paper should be regarded as an attempt to reconcile various schools of statisticians. By accepting what we regard 88 good and useful in the various approaches we are trying to develop a nondogmatic approach. 相似文献

Using a model of wage determination that allows for wage inertia, price expectational and price catch-up influences and quarterly
data on annual wage change in new major Canadian settlements for 1967–1987, this paper shows that the Anti-Inflation Board
(AIB) wage control programme has a much larger wage restraining influence than is estimated in previous studies. In contrast,
the Six and Five wage control programme exerts only a modest restraining influence. Both results are of special interest because
the wage determination model used here allows for not only the direct effect of wage controls, but also the indirect wage
restraining effect of controls operating through lagged wage changes.

The present paper provides the original formulation and a joint response of a group of statistically trained scientists to fourteen cryptic issues for discussion, which were handed out to the public by Professor Dr. D.R. Cox after his Bernoulli Lecture 1997 at Groningen University. 相似文献

Between 1982 and 1988 a growth study was carried out at the Division of Pediatric Oncology of the University Hospital of Groningen. A special feature of the project was that sample sizes are small and that ages at entry may be very different. In addition the intended design was not fully complied with. This paper highlights some aspects of the statistical analysis which is based on (1) reference scores, (2) statistical procedures allowing for an irregular pattern of measurement times caused by missing data and shifted measurement times. 相似文献

Using Meta-Analysis and GIS for Value Transfer and Scaling Up: Valuing Climate Change Induced Losses of European Wetlands 总被引:2,自引:0,他引:2

There is growing policy and academic interest in transferring ecosystem service values from existing valuation studies to other ecosystem sites at a large geographic scale. Despite the evident policy demand for this combined transfer and “scaling up” of values, an approach to value transfer that addresses the challenges inherent in assessing ecosystem changes at a national or regional level is not available. This paper proposes a methodology for scaling up ecosystem service values to estimate the welfare effects of ecosystem change at this larger geographical scale. The methodology is illustrated by applying it to value the impact of climate change on European wetlands for the period 2000–2050. The proposed methodology makes use of meta-analysis to produce a value function. The parameters of the value function include spatial variables on wetland size and abundance, GDP per capita, and population. A geographic information system is used to construct a database of wetland sites in the case study region with information on these spatial variables. Site-specific ecosystem service values are subsequently estimated using the meta-analytic value function. The proposed method is shown to enable the adjustment of transferred values to reflect variation in important spatial variables and to account for changes in the stock of ecosystems. 相似文献
