Synopsis We describe the first effort at creating a global ex-vessel fish price database, which is required for understanding the economic
behavior of participants in the world’s fisheries. We demonstrate potential applications of the database by linking it to
a spatially defined catch database, which makes it possible to attach landed values to species in both time and space. This
is the first database available publicly where interested members of the public, researchers and managers can easily find
and access ex-vessel prices of the world’s major commercial fish species. Preliminary results indicate that the average real
price of a number of species have declined between 1950 and 2002. The estimated landed value of fish globally, in year 2000
dollars, was about US$24 billion in 1950. It increased steadily to about US$90 billion in the early 1970s, reached a peak
of US$100 billion at the end of the 1980s, and declined to about US$80 billion in 2000. The top 15 fishing countries cumulatively
account for 79% of total real landed value, with Japan leading, even though the value of its landings has been declining.

Many medium-size cities suffer from severe traffic congestion and poor accessibility, limiting their potential to improve their economy, environment, and social equity. These problems could be addressed by creating high-quality transit linking such cities with suburban and other catchment areas through use of existing rail lines and abandoned former railway alignments. This concept, termed ‘Swift Rail’, would call for an innovative approach to local railway and transport development. 相似文献

The railway system in London and the south east is fundamental to London in its roles as the capital of the country and as a world-class financial and business centre. This article examines the formal strategies for spatial planning and railway investment in London and the south east and shows that there is a distinct dichotomy between spatial and transport planning. The authors explain the key investments needed in the network. They call for the Government to demonstrate how land use planning and transport investment are dovetailed together and properly funded, and for the Strategic Rail Authority to act more in concert with regional and local interests. 相似文献

A simulation study on the possibilities to reproduce a ‘true’ rank order of preferences and an underlying configurational structure of weighted distances between ideal points and real stimulus objects by PREFMAP-2 (Phase 2) is performed. Eleven hypotheses are evaluated with respect to three measures of reproduction quality. The results are mainly derived from three-way analyses of variance. Input rank orders can be reproduced quite well. This is not true for the underlying configurational designs, from which input rank orders are thought to be derived. Cluster designs, small numbers of stimulus objects and error are main effects to limit the quality of the results. 相似文献

In recent years, a growing literature has claimed that the market microstructure is sufficient to generate the so-called stylized facts without any reference to the behaviour of market players. Indeed, qualitative stylized-facts can be generated with zero-intelligence traders (ZITs) but we stress that they are without any quantitative predictive power. In this paper we show that in most of the cases, such qualitative stylized facts hide unrealistic price motions at the intraday level and ill-calibrated return processes as well. To generate realistic price motions and return series with adequate quantitative values is out-of-reach using pure ZIT populations. To do so, one must increasingly constrain agents?? choices to a point where it is hard to claim that their behaviour is completely random. In addition we show that even with highly constrained ZIT agents, one cannot reproduce real time series from these. Except in a few cases, first order moments of ZITs never equal real data ones. We therefore claim that stylized facts produced by means of ZIT agents are useless for financial engineering. 相似文献

Positive leniency in self-appraisal was studied for its cross-cultural properties in three Asian and three Western countries. Nine hundred and eighty-three mid-level bank managers were surveyed by indigenous field workers to measure self-appraisal, life goals, and other demographic variables. Positive leniency was found in the three Western countries but not in the three Asian countries while controlling for size and type of organisation, managerial level and several demographics including sex, age, education and religious preference. Our measure of self-appraisal also served as a measure of organisational success. The relationship between success and work motivation was then examined for its cross-cultural properties. Organisational success and work motivation correlated across the six countries although the intensity of work motivation varied. The importance of work and of family were highly valued in all six countries as well. 相似文献

ABSTRACT The results of this study suggest that marketing strategies need to be adjusted to changing cultures. Culture affects marketing decisions regarding product, price, promotion and place (the 4 Ps). Many marketing studies have been reported based on Hofstede's seminal work on national culture (1980). Marketing managers need to be cautious about assuming the validity of the Anglo cluster equating the cultures of the United States (U.S.) and Canada. We should recognize that national cultures are changing in the U.S., Canada and Mexico, as well as most other countries in the world. Our findings for a very recent sample of people attending executive and MBA programs would seem to apply to the upwardly-mobile business class. Contrary to the ubiquitous Hofstede data found in textbooks, we found no significant differences in Power Distance between the U.S., Mexico and Canada. Our findings regarding differences in Uncertainty Avoidance show that Mexico did not have a significantly higher mean than the U.S., but that the U.S. had a higher mean than Canada. The U.S. and Canada did not differ significantly on Individualism/Collectivism. Our results suggest that caution should be taken in automatically assuming cultural parity between the U.S. and Canada and that established cultural positions between the North American Free Trade Agreement (NAFTA) member nations may be changing. 相似文献
