Children at Play

Alchemy was frequently described in terms of women s work and children s games , by which it was implied that the processes were both repetitive (such as washing sheets) and also playful once they had been mastered (as in the joy of children at play.) Paracelsus described alchemy in terms of the daily activities of baking bread, making wine or weaving a cloth ... 

EXT. SOMEWHERE IN THE FOREST—DAY Meryl is out of breath. Anna is still in the lead, staggering ahead. They approach a group of five children at play. They have not seen other children in a long time. They stand statuesque for a moment and then are lured in by the children s game. 

The layman is keenly aware of the salient roles that variation and selection play in the realization of useful varieties in animal husbandry and agriculture. The richness of life forms of the animal and plant world, for food, labor, and esthetic appreciation are all primarily the result of the processes of variation and selection whether applied consciously or unconsciously by man and nature. The artist is keenly aware of the technique of variation and selection as in the development of themes into symphonies in music, in the plastic and pictorial arts, and in architecture. City planning, cooking in the home, adaptation of natural resources such as the harnessing of river systems, and children at play, all share methodologically a common bond with molecular modification and pharmacologic selection. 

It is known that zinc and cooper play an important role in immune system functioning (Kelley et al., 1995 Skalny and Rudakov, 2004 Zinc, 2001). Deficiency of these metals causes immune system dysfunctions. Recently these dysfunctions are seen to be widely distributed, especially in children. It is known also that sensitivity of the immune system to external influences differs in different age periods and it was found (Evstafyeva et al., 2002) that the influence of toxic metals is more significant in 7-11-year-old urbanized children. At the same time zinc and cooper deficiency was found in 1-6-year-old children, zinc deficiency and copper lowered contents, in... 

Following this success, Leopold was inundated with invitations for the children to play, for a fee. Leopold seized the opportunity and booked as many concerts as possible at courts throughout Europe. A concert could last three hours, and the children played at least two per a day. Today, Leopold might be considered the worst kind of stage parent, but at the time, it was not uncommon for prodigies to make extensive concert tours. Even so, it was an exhausting schedule for a child who was just past the age of needing an afternoon nap. 

EXT. SOMEWHERE IN THE FOREST—DAY They are playing King of the Mountain. The sun slightly begins to set. As Meryl is about to reach the top, WE FAINTLY HEAR THE SOUNDS OF HORSES. The children continue to play. The children stop playing. They look up at MERYL and stare in terror. THREE DARK KNIGHTS ARE ON HORSEBACK BEHIND MERYL. The children look down at ANNA S hands and back away. 

At hazardous waste sites, radiostrontium that is found in excess of natural background levels is most likely to be in soil and presents a special hazard for young children. Hand-to-mouth activity resulting in inadvertent soil consumption or intentional consumption of soil (pica behavior) will result in oral exposure to radiostrontium. Young children often play close to the ground and frequently play in dirt, which increases their dermal exposure to radiostrontium in dust and soil. The degree of hazard in each case depends on the form of strontium present at the waste site. 

A similar situation can arise in our children s play area. Seeing that the attendant is trying to return the balls to the bin, the kids might take on the challenge and begin to try to throw the balls out the opening. This increases the rate of escape and at first allows them to get ahead of the poor attendant, but as the concentration of the balls on the floor increases, his rate of return increases until the two rates are again equal. 

The main stream of the chemistry community either de facto ignored most of this theoretical effort, or considered it with the sympathetic eye of the wise father looking at children s play indeed, everybody knows that chemistry is to be carried out in a laboratory, and in a laboratory only. 

In one study undertaken at a children s hospital, Han et al. [53] observed a doubling in patient mortality which coincided with an implementation of a CPOE system introduced in an attempt to reduce clinical risk. Interestingly two other smdies were carried out on different implementations of the same system. One showed no impact on mortality [54] whilst the other showed some reduction [55] perhaps suggesting that factors relating to the deployment and implementation of the system rather than the application itself were at play. 

At 51 40, coach Joe Soares is out of the hospital. On a visit to his childhood home in Rhode Island, he tells us a bit more about himself. Born in Portugal, he describes himself as living the American dream— in other words, this adds even more texture to the fact that he s coaching Canada. But as we see him play with children at the house, we have a sense, confirmed by his sisters, that Joe is different since his illness we see him bragging to childhood neighbors about his son. (A transformation like this, while important to good drama, can never be manufactured or overstated. Jf it happened, great if it didn t, you... 

A comparison of results obtained on children and adults solving the same problem in either individual or paired conditions has not yet been done. However a few studies of constructive interaction among adults (e.g. O Malley etal. 1985, Miyake, 1986) suggest that mechanisms at play could be similar to those involved in children interaction. Noticeably, these authors refer to inter-individual conflict and a distribution of roles ( task-doer and criticizer) between the partners.
