This study explores the relationship between perceived bridging social capital and specific Facebook-enabled communication behaviors using survey data from a sample of U.S. adults (N=614). We explore the role of a specific set of Facebook behaviors that support relationship maintenance and assess the extent to which demographic variables, time on site, total and “actual” Facebook Friends, and t...

The study of geo-social behaviors has long been a scientific problem. In contrast to traditional social science, which suffers from the problems such as high data collection cost and imported user subjectivity, a new approach is presented to study social behaviors based on mobile phone sensing data. Different from other similar studies on mobile social sensing, three different types of geo-soci...

Emergency evacuation (egress) is considered one of the most important issues in the design of buildings and public facilities. Given the complexity and variability in an evacuation situation, computational simulation tool is often used to help assess the performance of an egress design. Studies have revealed that social behaviors can have significant influence on the evacuating crowd during an ...

In many vertebrates, reproduction is regulated by social interactions in which dominant males control access to females and food. Subordinate males that displace dominant individuals must rapidly adopt behavioral and physiological traits of the higher rank to gain reproductive success. To understand the process of phenotypic plasticity during social ascent, we analyzed the temporal expression p...

Chimpanzee is the most intellectual species among the animal kingdom. One-year (2009-2010) study on Chimpanzee was conducted to access the impact of captivity on their social behavior at Lahore Zoo. The group consisted of two pairs; one adult and other sub-adult housed in two separate cages. The data was recorded by instantaneous point-sampling technique to determine the frequency, prevalence a...

Adaptive trade-offs between foraging and social behavior intuitively explain many aspects of individual decision-making. Given the intimate connection between social behavior and feeding/foraging at the behavioral level, we propose that social behaviors are linked to foraging on a mechanistic level, and that modifications of feeding circuits are crucial in the evolution of complex social behavi...

An important extension to our understanding of evolutionary processes has been the discovery of the roles that individual and social learning play in creating recurring phenotypes on which selection can act. Cultural change occurs chiefly through invention of new behavioral variants combined with social transmission of the novel behaviors to new practitioners. Therefore, understanding what make...

years of age worldwide (39%). also in iran it is the cause of 45% of deaths. cardiovascular diseases place a huge social, economic and health burden on the society. patients suffer from this disease when they are at their highest social and economic productivity. the risk of this disease is related to modifiable factors such as smoking and high blood pressure, and also non-modifiable factors su...
