A Global Ex-vessel Fish Price Database: Construction and Applications

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.      

How much does tax erode fund excess returns?

We model the tax drag from active fund management based on reported monthly holdings of active equity funds. Tax drag erodes 65 percent of the 0.74 percent excess return in Broad Market funds, but only 21 percent of the 1.80 percent excess return in Small-Cap funds for Australian superannuation (pension) fund investors. Tax drag varies with investment style; market state, which is most detrimental during bull markets; and fund turnover. For high-income individual investors, tax drag is exacerbated to the extent that active management only generates meaningful after-tax excess return for Small-Cap funds of certain styles.     

‘Swift Rail’—funding local rail transit through smarter growth

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.     

Motives for a secular pilgrimage to the Gallipoli battlefields

Pilgrimage is a journey to a non-substitutable site embodying the highly valued, the deeply meaningful, or a source of core identity for the traveller. Secular pilgrimage is an important yet under-researched sector of the tourism industry. Where the motives for religious pilgrimage are well documented, little is known of the motives for secular pilgrimages. This paper presents the results of an empirical investigation of one case of secular pilgrimage, the journey of Australians and New Zealanders to the Gallipoli battlefields in Turkey. Five distinct motives for visits to the pilgrimage site are identified – spiritual, nationalistic, family pilgrimage, friendship and travel motives – and differences in their importance noted across seven visitor groups. These motives share some commonality with the motives for religious pilgrimage, and conversely, with the motives for leisure tourism; yet, other motives are unique to the secular pilgrimage. Suggestions for future research on secular pilgrimage are provided.     

Spatial Planning and Transport in London and the South East—Can Policy Co-Ordination and Delivery be Achieved?

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.     

Computing maximin efficient experimental designs using the methods of semidefinite programming

In the paper, we solve the problem of computing the maximin efficient design with respect to the class of all orthogonally invariant criteria. It turns out that on a finite experimental domain, the maximin efficient design can be computed by the methods of semidefinite programming. Using this approach, we can deal with the non-differentiability inherent in the problem, due to which the standard iterative procedures cannot be applied. We illustrate the results on the models of polynomial regression on a line segment and quadratic regression on a cube.     

Self-appraisal,life goals,and national culture: An asian-western comparison

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.     

A conditional distribution approach to uniform sampling on spheres and balls in Lp spaces

Liang and Ng (Metrika 68:83–98, 2008) proposed a componentwise conditional distribution method for L _p -uniform sampling on L _p -norm n-spheres. On the basis of properties of a special family of L _p -norm spherical distributions we suggest a wide class of algorithms for sampling uniformly distributed points on n-spheres and n-balls in L _p spaces, generalizing the approach of Harman and Lacko (J Multivar Anal 101:2297–2304, 2010), and including the method of Liang and Ng as a special case. We also present results of a numerical study proving that the choice of the best algorithm from the class significantly depends on the value of p.
