We often describe lives (or parts of lives) as meaningful or as not meaningful. It is also common to characterize them as more or less meaningful. Some lives, we tend to think, are more meaningful than others. But how then can one compare lives with respect to how much meaning they contain? Can one? This paper argues that (i) only a notion of rough equality can be used when comparing different ...

In general, the result of the elimination of weakly dominated strategies depends on order. We define nice weak dominance. Under nice weak dominance, order does not matter. We identify an important class of games under which nice weak dominance and weak dominance are equivalent, and so the order under weak dominance does not matter. For all games, the result of iterative nice weak dominance is a...

this experiment was conducted to determine gene action for different traits of chickpea including days to 50% flowering, days to maturity, plant height, 100-seed weight, number of primary branches, and number of pods per plant and seed yield since 2006 to 2009 in sararood dry land research sub institute in kermanshah. five genotypes arman, hashem, ilc588, iccv2 and ilc3279 were selected and cro...

In this study, 76 men came into the lab in pairs and engaged in a 7-minute videotaped mate competition for the attention of an attractive female confederate. Pre-competition testosterone (T) levels were positively associated with men’s dominance behaviors and with how much the confederate indicated that she ‘‘clicked’’ with each participant. Dyadic analyses showed that self-reported dominance m...

objective: in recent years different hypotheses with respect to the formation of cerebral laterality were proposed. some of the researchers claim that cerebral dominance and laterality are determined by genetic factors, just as the case with eye color and blood type. however, another group states that in addition to genetic factors, environmental factors, too, have a remarkable role in hemisphe...

Handedness and eye-dominance are undoubtedly associated statistically, although a previous meta-analysis has found that the precise relationship is difficult to explain, with about 35% of right-handers and 57% of left-handers being left eye dominant. Of particular difficulty to genetic or other models is that the proportions are distributed asymmetrically around 50%. The present study asked whe...

In response to the commentaries on our paper (Spencer et al., 2009) we summarize what a developmental systems perspective offers for a twenty-first century science of development by highlighting five insights from developmental systems theory. Where applicable, the discussion is grounded in a particular example-the emergence of ocular dominance columns in early development. Ocular dominance col...

The development of ocular dominance columns in primary visual cortex has attracted much interest from both experimentalists and theoreticians. One key parameter of these columns is their periodicity - it is thus important to understand how this is determined. Novel experimental work demonstrates that the periodicity is influenced by the temporal patterning of afferent activity, as predicted by ...
