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...

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...

The genus Vanhartenidia Lelej, 2006 is newly recorded from Egypt. A new species, V. mandishaensis El-Torkey & Soliman, sp. nov. is described and illustrated from Bahariya Oasis (Giza, Egypt).

The paper reviews the relationship between spatial and transportation planning in the Southern African Development Community (SADC) region of Sub-Saharan Africa. It argues that most urbanisation in the region has largely occurred subsequent to the 1950s and, accordingly, urban development has been profoundly and negatively affected by the (misguided) spatial and institutional tenets of modernis...

The significance of light massive neutrinos as hot dark matter is outlined. The power of neutrino oscillation experiments with respect to detect such neutrinos in the eV-region is discussed. Present hints for neutrino oscillations in solar, atmospheric and LSND data are reviewed as well as future experiments and their potential.

The two lead articles for this issue by Shamian and El-Jardali and by Clements, Dault and Priest provide an opportunity to consider how two agendas - teamwork in healthcare and the healthy workplace - can be strengthened to gain mutual advancement. Both agendas are in the pan-Canadian Health Human Resource (HHR) strategic plan in Canada and were also identified within the Health Council of Cana...
