The Colorado River system exhibits the characteristics of a heavily over-allocated or 'closing water system'. In such systems, development of mechanisms to allow resource users to acknowledge interdependence and to engage in negotiations and agreements becomes necessary. Recently, after a decade of deliberations and environmental assessments, the Glen Canyon Dam Adaptive Management Program (GCD...

This is an account of a general helminthological survey of Southern Rhodesia, a tract of country 151,000 square miles in area with a native population of 1,040,000, with 48,000 Europeans and about 4,000 Asiatics. The time occupied in this extensive work was only nine months, and the technical staff apparently only consisted of Dr. Blackie and Mr. McDonald. As a consequence of attempting such a ...

The rapidity of environmental degradation and the recent popularity of the concept of sustainability have made clear how successful traditional societies have been in coexisting with nature. Architects, in responding to this rising awareness, are searching for models of the reinterpreta­ tion of tradition, seeking examples and guidelines. Three practitioners who anticipated the need for a reexa...

The article sheds light on how ecotourism can be organized in Southern Africa using newer business models as the point of reference. Using chaos theory, the resource based view and dynamic competencies as theoretical basis, the article illustrates how firms within ecotourism can find new ways of organizingas means to become more competitive given a more dynamic and turbulent business environmen...

Atmospheric neutrino and solar neutrino data from the first phase of Super-Kamiokande (SKI) are presented. The observed data are used to study atmospheric and solar neutrino oscillations. Zenith angle distributions from various atmospheric neutrino data samples are used to estimate the neutrino oscillation parameter region. In addition, a new result of the L/E measurement is presented. A dip in...

Characteristics of the El Niño–Southern Oscillation (ENSO), such as frequency, propagation, spatial extent, and amplitude, strongly depend on the climatological background state of the tropical Pacific. Multidecadal changes in the oceanmean state are hence likely tomodulate ENSOproperties. To better link background state variations with low-frequency amplitude changes of ENSO, we develop a diag...

The theory of noise-induced phase transitions in a pendulum with a randomly vibrating suspension axis is outlined. It is shown that such transitions are associated with ordering of the system state. The results of numerical simulation of the transitions under consideration are given. The problem of distinguishing noiseinduced oscillations and chaotic oscillations of dynamical origin is discusse...

The main features of four-neutrino 3+1 and 2+2 mixing schemes are reviewed, after a discussion on the necessity of at least four massive neutrinos if the solar, atmospheric and LSND anomalies are due to neutrino oscillations.

We show that the redshift-space quadrupole will be a powerful tool for constraining dark energy even if the baryon oscillations are missing from the monopole power spectrum and bias is scale and time dependent. We calculate the accuracy with which next-generation galaxy surveys such as KAOS will measure the quadrupole power spectrum, which gives the leading anisotropies in the power spectrum in...
