Some research indicates that since the 1980s human demands on the biosphere have exceeded its regen-errative capacity. One way to solve this problem is to minimize the inappropriate ex-ploitation from environment. This essay wil focus on energy self-sustained project, which is a specific way to reduce energy requirements. Energy self-sustained project refers to that energy production is equal to the amount consumed. Three concepts are quoted in the fol-lowing to assess whether the project achieve zero-energy or not. First, ecological footprint, which provides an indication of the human load on the biosphere, is uti-lized to measure the inputs and outputs of the bioregion, which is also beneficial for defining the potential energy. Another one is life cycle assessment, which evaluates environmental load that relates to the entire life periodic system of a product, is helpful to measure the products used in the energy self sustained project. In addi-tion, net energy, and gross resource abundance, definitions for selection, or hierar-chy of different energy resources, can evaluate the new energy resources in project. Geos Neighbourhood, located in colorado, was planned as the largest net-zero energy neighbourhood in the United States. To meet the energy self sustainability, earth and sun power completely sustain the community＇s energy needs, and re-place al fossil fuels. Compared with the traditional communities, Geos Neighbour-hood minimize the adverse impact on the environment. As tools for assessment, ecological footprint, life circle assessment, and net energy, are al used to analyse the planning and design principles in the neighbourhood. By the research, the de-sign principles and energy use in Geos Neighbourhood wil be re-examined that whether the zero energy project achieves the reduction of ecological footprint, and energy self sustainability. In addition, life circle assessment wil re-examine the ma-terials used in the community also. Final y, the concept of ＇net energy＇ wil test solar energy and earth power which is the major energy used in Geos Neighbour-hood.展开更多

This research paper introduces a self-assessment instrument that focuses on ten major finance topics and reports the results of the administration of the self-assessment tool for finance education at the undergraduate and graduate level in courses taught in the United States and abroad. Ten topics of importance to most finance curriculum design were selected as the focus topics. The research methodology employed uses a pre-/post- test comparison with ＂understanding＂ being measured on a five-point Lichert scale as implemented in five different fmanee courses. Significant measurable differences occurred in each of the courses using this finance assessment instrument with overall average improvement of understanding by the students as much as one entire point. For exarnple, 1.5 mean score for the pre-test and 2.4 mean score for the post -test for an introductory finance class at the undergraduate level in a college of business. Additional improvements were assessed in each of the courses surveyed.展开更多
