Macroeconomics, One important feature of today's global environment is global trade which, if you remember history class, isn't new. Countries and organizations have been trading with each other for centuries. Global trade today is shaped by two forces: regional trading alliances and trade mechanisms that ensure that global trade can happen. When organizations do go international, they often use different approaches. Managers who want to get into a global market with minimal investment may start with global sourcing (also called global outsourcing), which is purchasing materials or labor from around the world wherever it is cheapest. The goal: take advantage of lower costs in order to be more competitive. A global manager must be aware of economic issues when doing business in other countries. First, it's important to understand a country's type of economic system. The two major types are a free market economy and a planned economy. A free market economy is one in which resources are primarily owned and controlled by the private sector. A planned economy is one in which economic decisions are planned by a central government. Actually, no economy is purely free market or planned. Question 31 What investigations are necessary to exclude secondary polycythaemia?

Question 35 What is the mechanism of development of splenomegaly in chronic leukaemia?

Question 36 In idiopathic thrombocytopenic purpura (ITP), thrombocytes are mainly destroyed in the spleen owing to an immune mechanism. Why, therefore, is there no splenic enlargement as there is with other diseases?

Question 37 Where exactly is the Traub's space? How exact is the percussion of the Traub's space as a sign indicating the size of the spleen?

Question 38 Can you please tell me the indications and complications of blood transfusion. Question 39 Several times I have read the phrase 'white blood cells elevated with a left shift'. I am wondering what 'left shift' or 'left deviation' stands for.
