Christmas carol social experiment

In the night of 18th of December, 2011, me, join a Christmas carol. He notice that six out of ten Filipino people do not give money if someone carols, making the Filipino people considered to be half parsimonious and half generous in a social conclusion.

I notice that some Filipino people do not give because of being busy, and just simply parsimonious. I also notice that abundantly, old people were the one who gives money to the children that carols. when old people were the one who carols, the parsimonious people became generous, how plastic, or they just respect the old people. It doesn't mean that we have just the word "po" and "opo", we are now respectful, no!, that is not enough. I thought Christmas was for everyone, but why?, where's the equality of the children and the old people.

Tropism

tropism (from Greek τροπή, trope, "a turning") is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the stimulus (as opposed to nastic movements which are non-directional responses). Viruses and other pathogens also affect what is called "host tropism" or "cell tropism" in which case tropism refers to the way in which different viruses/pathogens have evolved to preferentially target specific host species, or specific cell types within those species. Tropisms are usually named for the stimulus involved (for example, a phototropism is a reaction to light) and may be either positive (towards the stimulus) or negative (away from the stimulus).
Tropisms are typically associated with plants (although not necessarily restricted to them).[1] Where an organism is capable of directed physical movement (motility), movement or activity in response to a specific stimulus is more likely to be regarded by behaviorists as a taxis (directional response) or a kinesis(non-directional response).
In English, the word tropism is used in sometimes derisive way to indicate an action done without cognitive thought: However, "tropism" in this sense has a proper, although non-scientific, meaning as an innate tendency, natural inclination, or propensity to act in a certain manner.

Chemotaxis


Chemotaxis is the phenomenon in which somatic cellsbacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by swimming towards the highest concentration of food molecules, or to flee from poisons (for example, phenol). In multicellular organisms, chemotaxis is critical to early development (e.g. movement of sperm towards the egg during fertilization) and subsequent phases of development (e.g. migration of neurons or lymphocytes) as well as in normal function. In addition, it has been recognized that mechanisms that allow chemotaxis in animals can be subverted during cancer metastasis.
Positive chemotaxis occurs if the movement is toward a higher concentration of the chemical in question. Conversely, negative chemotaxis occurs if the movement is in the opposite direction.

Weissenberg effect

The Weissenberg effect is a common phenomenon that occurs when a rotating rod was place to a Non-Newtonian fluid. It creates a hurricane-like structure that is cause by a long chain of molecules. It was named after Karl Weissenberg who discover this effect. The Weissenberg effect(http://www.sumitomoseika.co.jp)
