Here's my definition of a professional image.  It consists of business attire in addition to being well-spoken and educated on whatever it is you do for a living.  Image isn't confined to the tangible but also what one exudes, IMO.

The word "SCHEMA" means BLUEPRINT. N/w schema, though not a standard term, it means the set of rules which have been laid to implement the n/w being talked about.\nThe Schema is designed on the basis of the protocol suit being used.\n\nIf you have heard about the Conceptual schema, etc in DBMS, this is similar to that; diff being in the technology ref to.

It sounds like it means don't overexamine things (level downward to our dullest perception) and use common sense.  Something like that.\n\nEverybody does need common sense though, if you think about it.  No matter how much higher education you have, if you don't have any common sense, you might be worse off than an auto mechanic who has common sense.  A business man with all of these degrees making choices without using common sense is a disaster waiting to happen.

The term 'blue' refers to 'blue laws' which were originally laws passsed in the U.S. that prevented people from transacting business on the Sabbath (Sunday). In time, the term 'blue laws' came to refer any law or rule that was designed to enforce personal morality. \n\nConsequently, actions that violated those moral codes were called "blue". A comedian who uses obscene language in his act is said to be 'working blue'. Likewise a film that features explicit extended sexual scenes that shock the public morality are called 'blue movies.'

Well, as you can see below, it could mean a "Bold Rooster", or a "Bold Gaullian" (for lack of a better name for one from Gaul).  It depends on the context.  For instance, if it is from Caesar, it is most likely referring to the Gauls.  But if it is about agriculture, cooking, etc...you get my point.

i grew up on a farm and know hard work ! we had forty acres to farm and had lots of animals too. i had to do chores before school while it was still dark outside ,then go to school then come home and do more chores. so i know lots of Americans willing to work ,not to mention the construction field , roofing ,cleaning. not every American has a college degree and the government is selling us out ! what will the blue collar working class do this is a very sad situation and its not a racial issue.

It means we place trust and confidence in police officers that we don't place in other people... just because they are police officers.  It means we expect them to behave in a trustworthy and capable manner, just because they are cops.  It has to do with the expectations we have of our uniformed officers... just because they wear the uniform.

The phrase "blue blood" is used to mean "from an aristocratic background," because pale, untanned skin–a sign of nobility–allows blue-tinged veins to show through.\n\nThat may be a probable reason for this phrase..

An unskilled worker is someone who has only the lowest level of qualifications, education, or experience. Unskilled or general (blue-collar) workers are distinguished from the clerical or salaried (white-collar) employees who have acquired specific skills [through a formal vocational education or training] which they place at their employers’ disposal. \nUnskilled workers are utilised to handle routine jobs within transport, handling, private security, agriculture, or monitoring of processes or stationary machines. \nOfficial statistics now use the definition of ‘wage earners in a job that presupposes skills at basic level’, and not the term ‘unskilled’.

It comes from the fact that if you work in a field or on a farm with your shirt on your neck and face and extremities will generally get sunburn, yet the core of your body will not. So, when that person takes off their shirt, they will have a 'redneck' in comparison with their body.  But in context it usually means a 'hick' a 'hillbilly' or a stereotypical southerner.
