Social Utility in Ultimatum Bargaining 总被引:3,自引:0,他引:3
In this article we will provide an overview of factors that influence the weight that self-interest and equity related motives receive in ultimatum bargaining. These factors are grouped into three main categories: factors relating to the context of the game, factors relating to the parties involved, and factors related to characteristics of the game. Results of the studies are discussed in relation to the concept of social utility. The authors point out possible omissions in the literature—especially the lack of interest for the behavior of recipients—and recommend directions for future research. 相似文献

The acetaldehyde accumulation in blood during the equilibration time of samples processed by gas-liquid chromatographic headspace technique is reported. The quantitative loss of blood ethanol concentration is recorded at various temperatures and times of the preheating process.When the equilibration process is performed at 40 °C, minimal errors, due to ethanol oxidation, are observed. 相似文献

Modifying and implanting existing RFID-tags into extracted human molars was described previously [P. Thevissen, G. Poelman, B. Puers, M. De Cooman, G. Willems, Implantation of RFID-tag into human molars to reduce hard forensic identification labor. Part 1. Working principle, Forensic Sci. Int. 156 (2006)]. Maximal vertical occlusal load during which the implanted RFID-tags remain active was evaluated in vitro. The temperature dependency of the implanted RFID-tags was studied on the extracted teeth to find out the maximal obtainable temperature before failure and a test with embedded thermistors to verify temperature distributions. The maximal working temperature of the implanted RFID-tags was revealed and gave indications for the set-up of measuring intra oral and intra tooth temperature during the cremation of a human body. Fatigue was induced on the implanted teeth by thermocycling. The results of this investigation showed the need of putting an extra insulating layer around the modified tags before implantation. The different in vitro tests indicated that the implanted RFID-tags can support certain oral and forensic circumstances. 相似文献

Major incidents occurred, occur and will still occur all over the world, at any place at any time. Such an event is not always handled like it should and could be. The reason for this is not necessarily a deficiency in preplanning or the non-existence of procedures or guidelines. A possible solution to make things work more fluidly could be the creation of a genuine vision and mission statement on disaster handling followed by the alignment of all involved services within the statement. This would be a real challenge for all authorities and services involved in the planning phase and the preparation for major incidents. 相似文献

Pink teeth have most often been observed in victims of drowning but have also been reported in subjects who died suddenly and unnaturally. There is general agreement that there is no obvious connection between the occurrence of pink teeth and the cause of death, but the condition of the surroundings (especially humidity) must certainly play an important role in the development of the pink-tooth phenomenon. The frequency and distribution of postmortem pink coloration of the teeth have been studied among a representative sample of 52 cadavers. All the bodies were victims of a single shipwreck that occurred on March 13, 1997, in the middle of the Otranto Canal (Mediterranean Sea). The bodies were recovered from the seawater after approximately 7 months. A distinct pink coloration of the teeth was found in only 18 cadavers (13 females and 5 males) of ages ranging between 13 and 60 years. The phenomenon was more pronounced in younger individuals due to age-related changes of the root canal, less penetrable by the pigment responsible for the postmortem pink staining. By histochemical methods and autofluorescence, hemoglobin and its derivatives have been identified as the most likely pigments responsible for this postmortem process that can be considered analogous to postmortem lividity. These data are consistent with previous reports on pink teeth, indicating that the diffusion of the blood in the pulp into the dentinal tubules causes the red discoloration of the teeth. Based on the results, the pigmentation is more prominent on the teeth with single roots rather than in the posterior teeth with multiple roots. 相似文献

This article based, on 38 in-depth interviews with Rotterdam cocaine retail dealers, aims to present a clearer picture of
how cocaine supply lines in the Netherlands are organized in order to fine-tune policy with respect to crime, public order
and safety on the different trade levels. On the retail level the market for cocaine is strictly separated in a market for
crack cocaine versus a market for powder cocaine. The crack dealers are often hard drug users themselves living in relatively
poor circumstances. Although dealing cocaine is their main activity, they tend to be involved in other activities related
to the drug scene, e.g. smuggling cocaine via Amsterdam airport. The cocaine distribution line for supply on the local market
is seldom more than two steps. Because the supply for the Rotterdam cocaine retailers comes mainly from small-scale imports,
successful police operations against large-scale imports of cocaine will have little influence on the local cocaine supply
in the Netherlands. 相似文献

A serious problem in questioned document examination is to establish the age of written lines. With respect to paper dating, in the past, Max Frei theory (based only on microscope analysis) claimed that strokes are time-dependent. Therefore, according to this theory, it has been asserted that from the analysis of the strokes depth changes it is possible to try to date the handwritten document (to find out that the document is older than ...). In the present work, we investigate the strokes depth change by a laser profilometer considering not only the time but also microclimatic variations. First, we analyze the stability of stroke characteristics along the time. In particular, we demonstrate that if the document is preserved without change of temperature and humidity, the depth of the strokes has not appreciable changes. In this way, we have the purpose to verify the real possibility of documents dating by means of Max Frei theory. Subsequently, we test how the 3D profile of strokes changes in connection with the microclimatic variations. In particular, we test humidity variations. With this experiment, we show that humidity variations reduce the strokes depth. Moreover, this effect shows a non-linear trend, leaving a hysteresis on the depth. Finally, we show that the analysis of 3D stroke profile is unable to determine the age of documents. 相似文献
