Few studies have focused on observable behavioral outcomes and findings have been mixed [ 5]. 'Students for Peace', a multi-component violence prevention project with 9000 middle school students, failed to reduce fights at school and absenteeism due to feeling unsafe at school [ 6].
Numerous studies have focused on the behavioral and physiological responses as well as potential longer term consequences of such disturbances to long-lived animals like water birds during different periods in their annual routine (e.g., Burger 1981; Bélanger and Bédard 1990; Madsen 1995; Béchet et al. 2004; Klaassen et al. 2006).
Although most studies have focused on morphological and behavioral traits [ 1- 4]), there is rapidly growing evidence of multiple genetic criteria of mate choice (reviewed in [ 5, 6]).
While risk factors for behavioral disorders have been identified in several studies, few studies have focused on the evolution of these disorders.
As only a few studies have focused on the detection of behavioral QTL in either the quail [ 11, 12] or the chicken [ 10, 13- 15, 51- 53], comparison with previous studies is less comprehensive than for production traits.
Most of the studies have focused on the cellular, physiological, morphological, behavioral, and reproductive phenotypic traits associated with new genes [ 1, 5- 7].
Few studies have focused on HIV/AIDS related behaviors by using health promotion theoretical frameworks in China [ 19], and no study has applied the information-motivation-behavioral skills (IMB) model to condom use among adolescents.
In Turkey, most studies have focused on the risk factors for early childhood caries and its behavioral, clinical and microbiological determinants [ 6- 9].
Most studies have focused on the critical impact of maternal care (or the lack of) on behavioral and brain development.
A number of studies have focused on the development of standard tests to evaluate the variability of the behavioral response of sheep to novelty, social isolation, attraction for conspecifics or the presence of a human [ 23– 26].
