A citizen scientist is a volunteer who collects and/or processes data as part of a scientific enquiry. Projects that involve citizen scientists are burgeoning, particularly in ecology and the environmental sciences, although the roots of citizen science go back to the very beginnings of modern science itself.

Ostensibly theoretical disputes in political science often involve competing approaches to explanation. Competing positions include skepticism, covering law arguments, reconstructions of propensities, system models, and explanations featuring causal mechanisms. Mechanismand process-based accounts including cognitive, environmental, and relational effects deserve more attention than they have re...

This paper will examine possible extinction properties of behavior-specific manual restraint. It will analyze the possibility of extinction being produced via restraint with respect to the target behavior’s possible environmental functions. The theoretical analysis will involve the analysis of behavioral properties of restraint during two temporal periods: (1) during the restraint itself and (2...

Environment may be considered as our surroundings which includes everything around us. Environment pollution is a big threat to the healthy existence of humankind. Several methods are involve in amelioration however, some of them are not possible in some situations or not economically and environmentally practical in other situation , Thus phytoremediation is a promising green technology to con...

since, in the same vein as public spaces, urban green spaces play a significant role in establishing social interactions in the iranian cities, security concerns need to be taken more seriously in such places than other social environments, the insufficiency of which could diminish their functional capacity. this could in turn lead to a source of subsequent difficulties in urban spaces. therefo...

this paper presents a mapping procedure for risk mapping of water and wind erosion, whichhelps to identify protective measures needed in the planning and management of natural parks. the map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (usle-rusle), and the map of wind erosion risk was developed using quirantes’ method. usi...

edi tor ’s note: NEHA strives to provide up-to-date and relevant information on environmental health and to build partnerships in the profession. In pursuit of these goals, we feature a column from the Environmental Health Services Branch (EHSB) of the Centers for Disease Control and Prevention (CDC) in every issue of the Journal. In this column, EHSB and guest authors from across CDC will high...

In the last decades, it has been demonstrated that many animal species orient in the Earth magnetic field. One of the best-studied examples is the use of the geomagnetic field by migratory birds for orientation and navigation. However, the biophysical mechanism underlying animal magnetoreception is still not understood. One theory for magnetoreception in birds invokes the so-called radical-pair...
