简介:the way a military general organises his army would affect the behaviour of the troops in battle. In the same way,the general must change his strategy accordingly. In other words,an existing organisation or structure should not be viewed as constraints to change if the strategy dictates that the change is necessary. In this aspect

简介:The title should be centered at the top of page 1 (DO NOT use a title page - it is a waste of paper for our purposes),The title is not a section,The body of the Results section is a text-based presentation of the key findings which includes references to each of the Tables and Figures. The text should guide the reader through your results stressing the key results which provide the answers to the question investigated. A major function of the text is to provide clarifying information. You must refer to each Table and/or Figure individually and in sequence (see numbering sequence)
