Within the concept of cultural tourism, this article defines relatively new concepts of creative and hobby tourism, which are detected as recent niche markets. Cultural tourism is a narrow specialized market, while creative and hobby tourism relate to even more specialized segments. Even these specialized forms of tourism have their market whose growth is very probable taking into account chang...

While caribou hunting structures are well known in the circumpolar region, equivalent features are difficult to investigate further south due to significant changes in sea level and subsequent human activity. The discovery of hunting structures on submerged landforms beneath modern Lake Huron provides a new window into caribou hunting in the mid-latitudes. This paper summarizes current findings...

The study of socio-technical systems has been revolutionized by the unprecedented amount of digital records that are constantly being produced by human activities such as accessing Internet services, using mobile devices, and consuming energy and knowledge. In this paper, we describe the richest open multi-source dataset ever released on two geographical areas. The dataset is composed of teleco...

A ta Enom ca Et Tustica, ol 2 (216), N o. 2, p. 10-236 ABSTRACT: Natura 2000 is often equated with protected areas where human activities are significantly limited or even excluded in order to preserve biodiversity. However, Natura 2000 is based on other settings. Most of the activities and projects in the Natura area can be carried out with the mitigation of possible negative impacts. Sometime...

The availability of food resources has been suggested as a major factor in the substantial increase in reproductive output, survival, recruitment and, ultimately, population growth rates in most organisms. In fact, the artiWcial increase in food availability resulting from human activities has been suggested as a factor in the substantial increase in population size of several seabirds in recen...

The slum question is not marginal to urban planning and social development – it is at its very heart. All the more so now that urban growth takes place primarily in developing countries in which populations move from rural to urban regions at a very fast pace. And around one billion of people (with a perspective of 2 billion in 2030), the third of the world’s total urban population, live in suc...

Observers segment ongoing activity into meaningful events. Segmentation is a core component of perception that helps determine memory and guide planning. The current study tested the hypotheses that event segmentation is an automatic component of the perception of extended naturalistic activity, and that the identification of event boundaries in such activities results in part from processing c...

Access to electricity, granting relative independence of human activity on the dark phase of the day, has been pointed out as an important cause for the absence of seasonal changes in the daily rhythms of humans living in urban areas. Featuring a population of adult Guarani natives living without access to electricity, the present naturalistic study was designed to explore possible effects of d...

desertification of the arid and semi-arid lands of the world has been proceeding for more than a thousand years.human-induced degradation in these areas is regularly cited as one of the principal causes of desertification.euphrates and tigris basin as the case study of this research in some aspects is almost unique in the world. but thisbasin has been confronted to progressive desertification. ...

concentrations of lead (pb) were found in the shells of the oyster saccostrea cucullata and sediments in may 2010. samples were obtained at four sites on qeshm island, at three sites on hormoz island, and at three sites in lengeh port along the intertidal coast of the persian gulf of iran. the levels of pb in sediments and shells were analyzed by graphite furnace atomic absorption spectrophotom...
