It is believed that health and safety of workers should be worked with children and early teenagers, the perspective that adults are more aware of these issues by providing them with health and quality of life in their daily lives, this is want the ERGOSHOW. The choice of media means for transmitting content of Ergonomics, Health and Safety (OSH) is justified because of the great popularity of ...

Three hypotheses concerning the control variables in visuomanual pointing were tested. Participants pointed to a visual target presented briefly in total darkness on the horizontal plane. The starting position of the hand alternated randomly among 4 points arranged as a diamond. Results show that during the experiment, movement drifted from hypometric to hypermetric. Final positions depended on...

The aims of this pilot study were to determine whether the weight of a backpack, its position on the spine or time carried affected adolescents cervical and shoulder posture. Standing posture measured from the sagittal and frontal planes of 13 students was recorded photographically under several load carrying conditions. Cervical and shoulder position angles were calculated and compared. Resul...

What is compassion? And how did it evolve? In this review, we integrate 3 evolutionary arguments that converge on the hypothesis that compassion evolved as a distinct affective experience whose primary function is to facilitate cooperation and protection of the weak and those who suffer. Our empirical review reveals compassion to have distinct appraisal processes attuned to undeserved suffering...

Point-light biological motion stimuli provide spatio-temporal information about the structure of the human body in motion. Manipulation of the spatial structure of point-light stimuli reduces the ability of human observers to perceive biological motion. A recent study has reported that interference with the spatial structure of pointlight walkers also reduces the evoked eventrelated potentials ...

We examine lateralization of lateral displays in convict cichlids, Amatitlania nigrofasciata, and show a population level preference for showing the right side. This enables contesting pairs of fish to align in a head-to-tail posture, facilitating other activities. We found individuals spent a shorter mean time in each left compared with each right lateral display. This lateralization could lea...

Nearly all species of sexually dimorphic ungulates sexually segregate. Several hypotheses have been proposed to explain this phenomenon, including the social-factors hypothesis (SFH) and the predation hypothesis (PH). Interestingly, previous studies have accepted and rejected each hypothesis within and across species but few studies have simultaneously tested both hypotheses in the same populat...

An increase in the period over which a muscle generates force can lead to the generation of greater force and, therefore, for example in jumping, to greater jump height. The aim of this study was to examine the effect of squat depth on maximum vertical jump performance. We hypothesized that jump height would increase with increasing depth of squat due to the greater time available for the gener...

The dynamic environment of a van modified to accommodate a person driving from a wheelchair was measured to determine the effects of position within the van and the type of seat used. The project measured accelerations as a subject sat in three positions within the van and upon two different seats. Three separate van maneuvers at different speeds were used to change the dynamic environment. Van...
