One hypothesis advanced to account for the greater retentivity of psychomotor behaviour, as compared to that of newly acquired verbal behaviour, is that nonverbal actions are more often overlearned and are less susceptible to proactive interference (i.e., competition arising from things learned in the past).
Therefore, the metal price should not be too high to lose the clients because of the drastic competition arising from the open market.
At present, due to a tendency to instrumentalize education in early childhood as a result of the competition arising from international tests over some fields of learning, a large number of Chilean educators have reacted by joining the Declaration that the World Organization of Early Childhood Education made in Gothenburg, Sweden last year on the "Right of Children to Play and Learn by Playing".
Competition arose from other genres.
One well-described staphylococcal mechanism is via competition arising from allelic variation within agr-dependent signal transduction (Regassa et al. 1992; Yarwood et al. 2002; Weinrick et al. 2004; Schlievert et al. 2007; Horswilll and Nauseef 2008; Peterson et al. 2008).
A major difference between the stem cell theory and the barrier theory is evident in the context of new oncogenic selective pressures such as those imposed by cancer therapy, resource restriction in the microenvironment, and within-tumor cell competition arising from new mutations.
Originally, disputes exist between the 'eye rivalry' theory that binocular rivalry arises from low-level competition between monocular neurons [9], and the 'stimulus rivalry' theory that binocular rivalry reflects high-level competition between stimulus representations [10].
With increasing challenges and competitions arising from globalization and a knowledge-based economy, the effective use of communications and information technology, and knowledge is the key to economic and social advancements.
However, our main result of clonal competition arises in a natural way from immune interactions.
Differences between this model and those studied in the literature on time competition arise mainly from the control variables, the type of market and the market mechanism.
The common factor among these previous studies is that despite sperm from each tactic facing different sperm competition conditions arising from different male competition behaviours, courtship behaviours, mating order, mating duration and sperm expenditure [ 33], how and where released sperm meet with eggs (i.e. fertilization environments) are basically the same among competing males.
