Measurement is fundamental in science. Social sciences generally and psychology, in particular, depend on objective, valid, and reliable psychometric scales. In the 20th century, the psychology of religion and spirituality spent a long time searching for comprehensive and trustworthy instruments to assess psychological constructs in the field of empirical studies of religion and spirituality....

Tourism is often introduced as a subject in formal education curricula because of the increasing and significant economic contribution of the tourism industry to the private and public sector. This is especially the case in emerging economies in Asia and Africa (Hsu, 2015; Mayaka Cuffy et al., 2012). Tourism in South Africa – which is the geographical setting of this research...

The Mott metal-insulator transition is investigated as a quantum phase transition. The U - t - t’ model at half-filling is considered as a paradigm; the sign of t’ is not relevant and is taken to be positive. The phase diagram presents two Mott insulating phases with distinct symmetries and one global metallic phase which is presumed to be a Luttinger liquid for the charge degrees of freedom....

The possibilities of industry to process and to engineer materials at the nanometer level rapidly increase and products using materials engineered at the nanometer level emerge on the markets. In the long term, it is hardly possible to estimate, from the present point, where the ability to engineer materials on the nano-scale will lead human beings, whether the dream of a molecular nanotechnology...

Despite the undeniable practical benefits of documentation during software development and evolution activities, its creation and maintenance is often neglected, leading to inadequate and even inexistent documentation. Thus, it is not unusual for developers to deal with unfamiliar code they have difficulties in comprehending. Browsing the official documentation, or accessing online resources,...

Nanotechnology, a research area that covers many scientific disciplines such as Medicine, Biology, Physics and Chemistry has found a great interest in research institutions and wide applications in industries. This is due to many reasons; from these we note the control down to the molecular level providing thereby a greatest efficiency and an important added value as a reason of the low cost of...
