The authors offer a new, integrative conceptualization of the relational self based on a synthesis of recent approaches to the self and significant others. This conceptualization provides a sharper and fuller definition of the relational self than does any existing approach alone and a common framework to interpret findings from separate literatures. The authors then present 5 propositions and ...

Thirty male volunteers participated in a study evaluating the effect of workspace envelope (work height and reach distance) and handle orientation on grip force capacity. Maximum voluntary power grip exertions were recorded using instrumented tool handles under three conditions: a pistol grip tool handle oriented horizontally and vertically and a right angle tool handle oriented horizontally. S...

The Naturally-Transitioning Rate-to-Force Controller (NTRFC) for manipulators is presented. In free motion rate control is provided, while in contact the same rate commands are proportional to the force exerted on the environment by the manipulator. The transition between free motion and stable contact with the environment requires no changes in control mode or gains and hence is termed natural...

We present our investigation of the torque exerted on dielectric elliptical cylinders by highly focused laser beams. The calculations are performed with rigorous diffraction theory, and the size-dependent torque is analyzed as a function of the axis ratio. It is found that highly elongated particles will experience a reversal of the torque for a radius that is approximately one third of the wav...

Usually in the presence of a background noise an increased effort put in controlling a system stabilizes its behavior. Rarely it is thought that an increased control of the system can lead to a looser response and, therefore, to a poorer performance. Strikingly there are many systems that show this weird behavior; examples can be drawn form physical, biological, and social systems. Until now no...

In this study we aim to examine how the implicit learning of statistical regularities of successive stimuli affects the ability to exert cognitive control. In three experiments, sequences of flanker stimuli were segregated into pairs, with the second stimulus contingent on the first. Response times were reliably faster for the second stimulus if its congruence tended to match the congruence of ...

This paper elaborates a recent conceptualization of feature-based attention in terms of attention filters (Drew et al., Journal of Vision, 10(10:20), 1-16, 2010) into a general purpose centroid-estimation paradigm for studying feature-based attention. An attention filter is a brain process, initiated by a participant in the context of a task requiring feature-based attention, which operates bro...

-The ship of progress of any country floats on the hard work and dedication of its young generation and its innovative thought. But now wide spread frustration has been found in the youths of society which is decreasing their work efficiency. So the present study has been conducted to study the unrest among graduate students in relation to their gender, intelligence, adjustment and educational ...

People vary in the occurrence and perceived severity of stressors experienced in their daily lives. In the current study, the authors examined the extent to which individual differences in these relatively minor occurrences are determined by genetic endowment as well as environmental influences and how these effects vary by age. Identical (n-sub(pairs) = 111) and fraternal (n-sub(pairs) = 99) t...
