The practice of assigning monetary values to ecological goods and services, in order to resolve what David Pearce calls the “zero price problem” has been a subject of debate practically since it was first proposed. At present, many working in the area of ecological economics are cautious of its use and even some who endorse monetary valuation justify its use on pragmatic rather than purely theo...

This study aims to assess niche segregation among the five main toothed whales 25 that frequent the NW Iberian Peninsula waters: the common dolphin, the harbour porpoise, 26 the bottlenose dolphin, the striped dolphin and the long-finned pilot whale. We used cadmium 27 (Cd) and stable isotope ratios (δ 13 C and δ 15 N) as ecological tracers to assess degree of 28 segregation in diet/trophic lev...

Given a sequence of n elements, the All Nearest Smaller Values (ANSV) problem is to nd, for each element in the sequence, the nearest element to the left (right) that is smaller, or to report that no such element exists. Time and work optimal algorithms for this problem are known on all the PRAM models 3], 5], but the running time of the best previous hypercube algorithm 6] is optimal only when...

BACKGROUND The RD(50) (exposure concentration producing a 50% respiratory rate decrease) test evaluates airborne chemicals for sensory irritation and has become an American Society for Testing and Materials (ASTM) standard method. Past studies reported good correlations (R(2)) between RD(50)s and the occupational exposure limits, particularly threshold limit values (TLVs). OBJECTIVE The main ...

A wetland inventory and assessment was made as a basis for development of a national wetlands policy for Colombia (CMWP). Major wetlands were identified from a 1:1 500 000 scale national hydrological map. Of 57 major wetlands in 27 catchments or wetland complexes, wetlands in 16 of these were selected for assessment. Wetland type, ecological status and wetland value for each wetland was scored ...

The paper examined the value system in Philippine firms against the backdrop of Eastern-Western cultural dynamics in East Asia. The Asian milieu presents co-existence of cultural stasis and unease -balance and tension between Eastern values and Western ideas. Successful Asian countries demonstrated their ability to blend conflicting cultures and highlight certain values in order to promote nati...

Modularity is a recurrent and important property of bipartite ecological networks. Although well-resolved ecological networks describe interaction frequencies between species pairs, modularity of bipartite networks has been analysed only on the basis of binary presence-absence data. We employ a new algorithm to detect modularity in weighted bipartite networks in a global analysis of avian seed-...
