In “A White Heron” by Sarah Orne Jewett‚ the main character Sylvia‚ is described as a “child of nature” who is somewhat cautious of those she does not know. For eight years‚ she lived in a “crowded manufacturing town‚”. Her grandmother‚ who rescued Sylvia from the city‚ believes that Sylvia had never been truly “alive” until her arrival on the farm. Sylvia believes she has found a comfortable home in the “out-of-doors.” and it is obvious that Sylvia feels more at home with a more “natural” society

Return on Shareholders Funds (ROSF) Ratio Definition: The Return On Shareholders Funds (ROSF) ratio is a measure of the profit for the period which is available to the ordinary shareholders with the ordinary shareholders’ stake in a business. Formula: Return On Shareholders Funds = ((Net profit after taxation & preference dividend) / (Ordinary share capital + Reserves)) * 100% Example 1: If the net income of PPC Ltd is $80‚000 whereas shareholder’s funds are $500‚000. Then‚ the ROSF =
