...115 Double loop learning in organizations By uncovering their own hidden theories of action, managers can detect and correct errors Chris Argyris Why are employees reluctant to report to the top that one of their company's products is a "loser" and why can't the vice presidents of another company reveal to their president the spectacular lack of success of one of the company's divisions? The inability to uncover errors and other unpleasant truths arises from faulty organizational learning, says this author. Such habits and attitudes, which alJow a company to hide its problems, lead to rigidity and deterioration. The author descrihes how this process can be reversed hy a method he calls double loop learning. Chris Argyris is James Conant Professor of Education and Organizational Behavior at Harvard University, and is the author of numerous publications on executive leadership and organizational effectiveness. Several years ago the top management of a multibillion dollar corporation decided that Product X was a failure and should be dropped. The losses involved exceeded $ioo million. At least five people knew that Product X was in serious trouble six years before the company decided to stop producing it. Three were plant managers who lived daily with the production problems. The two others were marketing officials, who perceived that the manufacturing problems could not be solved without expenditures that would raise the price of the product to the point where...

...MA, Gustin MS, Zhang H, 2001) Once in the atmosphere, it can be deposited in soils and waters, hence causing harm to the environment or the people who would later drink from the water. The Clinton White House defined green manufacturing as a process that reduces human and ecological tasks, enhances, cost effectiveness, improves process efficiency, and creates products and processes that are environmental friendly and benign (President, 1995). Having this stated, green manufacturing is a process that improves productivity, competitiveness, and profitability. The benefits of having a green manufacturing process in an organization’s production are immeasurable. While it may be tough and expensive to implement a greener technology in a production, green technology would nevertheless save a lot of money for an organization. A good example of this would be the production of compact fluorescent lamp where it produces the same amount of visible light as an incandescent light bulb, it uses lesser energy while having a longer life time. This cost saving benefit has been taken by organizations to redesign their production process. Indeed, those organizations...

The objective of this paper is to provide a means of renewable hydrogen based fuel utilization. The development of a high efficiency, low emissions electrical generator will lead to establishing a path for renewable hydrogen based fuel utilization. A full-scale prototype will be produced in collaboration with commercial manufacturers. The electrical generator is based on developed internal combustion engine technology. It is able to operate on many hydrogen-containing fuels. The efficiency and emissions are comparable to fuel cells (50% fuel to electricity, ~ 0 NOx). This electrical generator is applicable to both stationary power and hybrid vehicles. It also allows specific markets to utilize hydrogen economically and painlessly. Introduction Two motivators for the use of hydrogen as an energy carrier...

...CHAPTER - 1 INTRODUCTION 1 INTRODUCTION OF THE STUDY In the modern world of tough competition and rivalry among the companies it has become necessary that one should be able to understand each and every aspect of the functioning of the organization than only concentrating on his work alone. So in order to make students aware of the overall working of the organization the university as well as the institution has made it mandatory to conduct a detailed study into the working of an organization and also to submit a report at the end of the study. Since the industrial revolution in the early 18th century, the world has witnessed a significant growth in the field of infrastructure, industry and allied activities. In India after the globalization in 1993, the foreign counterparts started coming to India and the need for doing project was realized and now it has become an important component of economic development. Projects are defined as an economic activity with well defined objectives and having a specific beginning and end. The engineering industry is one of the second largest components of India‟s manufacturing sector over the year. This particular sector has registered an average growth of 16% during the last two decades. It includes production of the electronic gadgets and machines and drives to run those machines. Need for the study To learn about the origin and development of the company. The role of each department in an organization dealing in industrial...

Amin In order to resolve the problem of low thermal and chemical stability of thermoplastic elastomers, dynamic vulcanization techniques were used in late ] plastic. In dynamic vulcanization the thermoplastic and elastomers are both cross-linked and physically mixed together. This gave rise to a second generation of thermoplastic elastomers which had better tensile strength and oil resistance as compared to those formed by physical mixing only [8]. ] ] ] _ were introduced which were made by same dynamic vulcanization process but using natural and butyl rubbers in place of EPR and EPDM. Natural and butyl rubbers have the advantages like low cost, very good over molding properties, reusable and very easily recyclable scrap [9,10]. Butyl rubber based thermoplastic elastomers have excellent adhesion with other thermoplastics hence it is still used to date for many over molding applications [11].

...（1） In 1945, just after World War II, the alliance between the United States, Britain and the Soviet Union ended. An intense rivalry between communist and non-communist nations led to the Cold War. It's called the Cold War because it never led to armed or "hot" conflict. At the end of World War II, at the Yalta Conference, Germany was divided into four occupied zones controlled by Great Britain, France, the Soviet Union, and the United States. Berlin was also divided into four sections. Lack of a mutual agreement on German re-unification was a important background of the Cold War. And on March 5, 1946, Winston Churchill, gave his "iron curtain" speech while at Westminster College in Fulton, Missouri, which marked the start of the Cold War. The cold war did not end until the collapse of the Soviet Union in 1991. During this period, the United States and the USSR confronted each other in politics, economy, ideology, and so on. And they nearly divided this world into two camps, socialist camp and capitalist camp, what made the conflict on ideology especially sharp. Every incident in the world could not happened without reasons, and the original cause may happened quite long ago. So there are long term causes and short causes of the Cold War. One of the short term causes is that the US President had a personal dislike of the Soviet leader Josef Stalin. At the Potsdam Conference starting in late July 1945, serious differences emerged over the future development of Germany and...

...Subject: Surface Engineering TERM PAPER TOPIC: SMART COATINGS Abstract: Materials that are capable of adapting their properties dynamically to an external stimulus are called responsive, or smart. The term "smart coating" refers to the concept of coatings being able to sense their environment and make an appropriate response to that stimulus. The standard thinking regarding coatings has been as a passive layer unresponsive to the environment. The current trend in coatings technology is to control the coating composition on a molecular level and the morphology at the nanometer scale. The idea of controlling the assembly of sequential macromolecular layers and the development that materials can form defined structures with unique properties is being explored for both pure scientific research and industrial applications. Several smart coating systems have been developed, examined, and are currently under investigation by numerous laboratories and industries throughout the world. Examples of smart coatings include stimuli responsive, antimicrobial, antifouling, conductive, self-healing, and super hydrophobic systems. In this paper a number of application-wise prominent smart coatings are discussed with their individual merits & demerits. INTRODUCTION: A new generation of anticorrosion coatings that both possesses passive matrix functionality and actively responds to changes in the local environment has prompted great interest from material scientists...
