Single-handedness

Recent experiments and observations, however, prove that single-handedness is merely the result of faulty or restricted education. Careful observations have shown that out of every hundred persons born into this world eighty are congenitally ambidextrous — that is to say, they will instinctively reach for an object with either hand

But as we rise in the evolutionary scale of normal creatures, and as we exclude disease, ambidexterity progressively gives way to single-handedness, generally right-handedness.

One step in my method of correcting the stutterer is to build up a single-handedness or sidedness in the individual.

In the complexes, the direction and affinity of the hydroxy group for hydrogen bond toward the carboxy group of poly-12 may be the most important factor to control both the helical sense and an extent of the single-handedness, and therefore, the complexes with amino alcohols showed an intense ICD independent of the bulkiness of the substituent (R) with the same Cotton effect signs as the primary amines.

So not only does the hand of the amino acids dictate the hand of the helix they form, but more profoundly, single-handedness appears to be necessary for helices to form at all.

In scientific language this preferred single-handedness is referred to as homochirality; nature clearly exhibits this, but the exact origins of this trait remain shrouded at present, though various theories have been postulated to try to explain how it first arose.

The process practices autarchy, exclusivism or single-handedness instead of a radical universalism, based on democracy and equality that can be achieved through a united struggle.

In the UK, much of the progress in general practice over the recent past has evolved in the context of group practice and the primary health care team — the credo of modern-day doctoring. Single-handedness puts a question mark over the primacy and validity of these ideas.
