Greening Curve Lessons Learnedin the design of the EPA Campus

By considering value broadly and making design trade-offs in other areas, EPA justified design decisions that might never have survived purely economic scrutiny, such as the use of certified sustainably-harvested wood. The VE modifications are interesting to study both for what they contain as well as for what they do not contain.

How to Make Fireproof Concrete

You can make your own fireproof concrete with materials available at home improvement stores. If you are planning to build blocks, you will need to have you forms ready beforehand so you can pour the mix right into the forms when the concrete is at the proper consistency.

Erikson's Psychosocial Theory of Human Development

Initiative is the capability to devise actions or projects, and a confidence and belief that it is okay to do so, even with a risk of failure or making mistakes. Guilt means what it says, and in this context is the feeling that it is wrong or inappropriate to instigate something of one's own design.

Objectives and Goal Setting

One of the best ways to tell whether or not an area is a clearly defined objective area, is to ask the question: Could I assign a person to be responsible for this area of activity? If you can assign a person, on a continuing basis, to be responsible for everything going on in their area, it is probably a clear objective area. Find more criteria for solid objective and goal setting.
