This review of the research literature on the heritability of criminal behavior organizes the studies by four basic research methodologies: family studies, twin studies, adoption studies, and gene-environment interaction studies. Interpretation of the relationships observed in these studies is made ambiguous and problematic by critical methodological inadequacies in the research itself: The met...

Two major characteristics of males that affect the likelihood of achieving copulation are the sexual motivation and mating competency of the male. The behavior of domestic animals, including their sexual behavior, is dependent upon a complex interaction between the organism's internal and external environment. In male pigs, as in other mammalian species, it is clear that testicular steroids are...

Nearly all aspects of human development are influenced by genetic and environmental factors, which conjointly shape development through several gene-environment interplay mechanisms. More recently, researchers have begun to examine the influence of genetic factors on peer and family relationships across the pre-adolescent and adolescent time periods. This article introduces the special issue by...

We review a range of studies on the genetic contribution to behavior in canid species. We begin by identifying factors that make canids a promising model in behavioral genetics and proceed to review research over the last decade that has used canids to identify genetic contributions to behavior. We first review studies that have selectively bred dogs to identify genetic contributions to behavio...

In addition to attention to natural light as a renewable, costless and environment-friendly source of energy in the late 20th century, numerous studies have been conducted into the effect of natural light on human being’s soul and body and all such studies reiterate the undeniable role of natural lighting on people’s behavior, attitudes, and efficiency. However, in spite of the awareness of the...

previous studies have shown that when people enter a new cultural environment which is different from their own culture, they face a lot of problems to adapt themselves with the new environment. this may result in intense dissatisfaction with the new situation. the data for the present study were collected from a randomly-selected sample of 300 people, from among a population of 1100, through q...

From the results of two Human behavior studies in small group interactions we constructed iteratively a Collaborative Virtual Environment named “VIRSTORY”. This system is a digital storytelling with speech and 3D gesture recognition technologies using like input devices. It includes several modules: multimodal interaction module, behavior module to animate autonomous expressive characters, etc.

Behavior setting theory was developed by Roger Barker to explain small-scale social systems, as well as the study of behavior in its natural environment. It is somewhat unusual in being both a big-T theory (its abstract superstructure) and a grounded theory (its research guiding part). Among its advantages are conceptual integrity and well defined terminology, readily available empirical confir...

Early experiences can modify regulatory factors affecting gene expression in such a way that, although the DNA sequence itself is not changed, the individual's physiology and behavior is substantially influenced. In some instances these epigenetic effects are exerted upon exposure, while in other instances they are transmitted across generations via incorporation into the germline. Examples of ...

In 2000, ETSI has approved and published a standard for interactive broadband satellite services (DVB-RCS) . One of the most important features of this standard is the implementation of DAMA strategies aiming at a fair and efficient use of the shared resources in the satellite return channel. A DAMA scheme introduces a new control loop, based on a signaling exchange between STs and the NCC, ins...
