Females of avian brood parasites, like the shiny cowbird (Molothrus bonariensis), locate host nests and on subsequent days return to parasitize them. This ecological pressure for remembering the precise location of multiple host nests may have selected for superior spatial memory abilities. We tested the hypothesis that shiny cowbirds show sex differences in spatial memory abilities associated ...

This paper presents the application of differential semantics to identify the semantic space (structure) used by men and women to describe their perception of properties on sale. 112 men and 43 women evaluated 112 images of flats on sale at the time of the study in the city of Valencia (Spain) using 60 adjectives. The set of attributes or variables which capture the user’s perception of a prope...

This study aims to investigate the gender differences in spatial navigation using the tasks of 2-D matrix navigation and recognition of real driving scene. The results can be summarized as followings. First, female subjects responded faster in 2-D matrix navigation task than male subjects when landmark instructions were provided. Second, in recognition task, male subjects recognized the key ele...

Observing Delta Scuti stars is most important as their multi-frequency spectrum of radial pulsations provide strong constraints on the physics of the stars interior; so any new detection and observation of these stars is a valuable contribution to asteroseismology. While performing uvby-beta photoelectric photometry of some RR Lyrae stars acquired in 2005 at the Observatorio Astronómico Naciona...

On the way to autonomous systems, one of the key issues concerns spatial reasoning what involves solving problems with uncertainty. From the starting point of human nature, information must be represented in a way that any system can reason with imprecise knowledge about different physical aspects and make correct decisions from them. Keeping this idea in mind, this paper presents the qualitati...

In most countries, females live several years longer than males. Many biological and behavioral reasons have been presented in the scientific literature to explain this “female advantage.” A crosssectional regression study, using 50 explanatory variables and data collected from 169 countries, provides support to the behavioral hypothesis. Four variables, unrelated to biological sex differences,...

BACKGROUND Employing innovative mapping and spatial analyses of individual and neighbourhood environment data, we examined the social, physical and structural features of overlapping street-based sex work and drug scenes and explored the utility of a 'spatial isolation index' in explaining exchanging sex for drugs and exchanging sex while high. METHODS Analyses drew on baseline interview and ...

the contemporary globalization which is based on post-fordist economy, was formed on the basis of informational capitalism, and has been differentiated from other concepts due to some characteristics like information economy, global economy, and network economic activities.     the characteristics of post-fordist economy create a situation where capitals and productions are changed from place-...
