Qualitative Insight 2: Energy and mass are complementarities particularly relevant in special relativity and space and time are complementarities in general relativity.
Now let us switch gears and look at the complementarities in quantum mechanics.
The complementarities we are considering are wave and particle.
In this paper, we first discuss three types of R&D strategies, which are internal R&D, external R&D and cooperative R&D, and then specify appropriate econometric models to explore the complementarities among these R&D strategies.
Our empirical results suggest that as the innovation output is measured either by the proportion of sales from new products or by the marginal rate of return on R&D investment, the complementarities among these R&D strategies are significant, and moreover, the complementary effect between internal R&D and external R&D is the strongest (8).
The first two innovation indicators are frequently used as dependent variables in previous studies on complementarities among R&D strategies.
Sexual moral norms must seek to facilitate the integration of holistic complementarity--that is, the integration of orientation, personal, and biological complementarities
. This integration does not allow for the absolute condemnation of particular sexual acts without due consideration of a person's sexual orientation and the meaning of this sexual act for persons in relationship--that is, in personal complementarity--which is expressed in and through genital complementarity.
This study, sponsored by the Friedrich Ebert Stiftung (FES), identifies the complementarities
and comparative advantages and benefits which the SAARC member-countries would gain by regional cooperation in land transport and communications.
In an economy without complementarities, markets have a strong role as shock absorbers.
By contrast, with complementarities there can be a magnification of small shocks.
Another potential result of complementarities is multiple equilibriums.
