...BACHELOR OF COMMERCE (B.COM.,) PAPER – 2.1 MANAGERIAL ECONOMICS UNIT – I CHAPTER - I SECTION - I Definition of Managerial Economics Managerial economics refers to those aspects of economics and its tools of analysis most relevant to the firm’s decision-making process. According to MeNair and Meriam, managerial economies consists of the use of economic models of thought to analyze business situations. Some writers consider managerial economics as the integration of economic theory with business practice for the purpose of facilitating decision-making and forward planning by management. The underlying idea of all these definitions is that managerial economics means economics applied in decision-making. So we may consider managerial economics as a special branch of economics bridging the gap between abstract theory and managerial practice. It may be pointed out here that effective decision-making at the firms’ level calls for a careful analysis of a choice between alternative courses of action. Economic theory offers a variety of concepts and analytical tools which can be of considerable assistance to the manager in his decision-making process. In fact actual problem-solving may require many skills and tools which are not available in the traditional economist’s. For example, knowledge of accounting and of statistical concepts and methods, which are not taught in economics, can help the analyses to apply more effectively the economic...

Jones Liadh Kelly Jaime Teevan Copyright ©2010 remains with the author/owner(s). Proceedings of the SIGIR 2010 Workshop on Desktop Search (Understanding, Supporting and Evaluating Personal Data Search). Held in Geneva, Switzerland. July 23, 2010. Preface These proceedings contain details on the invited talks and the papers presented at the SIGIR 2010 Workshop on Desktop Search (Understanding, Supporting, and Evaluating Personal Data Search), Geneva, Switzerland, 23 July, 2010. Despite recent research interest, desktop search is under-explored compared to other search domains such as the web, semi-structured data, or flat text. Even with the availability of several new desktop search tools, users are more successful finding information through browsing their personal collections and subsequently show preference for this approach. Problems with existing desktop search tools include performance issues, an overreliance on good query formulation, and a failure to fit within the user’s work flow or the user’s mental model. As the available storage for desktop collections becomes cheaper and more plentiful and new media types continue to appear, the size and types of items stored in personal collections is growing rapidly. The need for effective methods...
