Beyond enmeshment: evidence for the independence of intrusiveness and closeness-caregiving in married couples.
In a 1996 article on family theory, we (Green & Werner) proposed that family enmeshment should not be equated with high cohesion and that the construct of enmeshment fails to discriminate between twoExpand

What is new about the new Comet Yanaka (1988r)
A deficiency in the observed abundances of C2 and CN in Comet Yanaka (1988r) is explained in terms of the properties of its organic refractory dust component and the fact that it is a new comet.Expand

Looking for the Homochiral Signature of Life: The Seth Cigar
One of the most characteristic features of life is its homochirality: all biomolecules are of one hand, e.g. terrestrial life is based on all-L amino acids and all-D sugars. Non-living systems areExpand
