Mathematical economics
1. Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. By convention, the applied methods refer to those beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, and other computational methods. An advantage claimed for the approach is its allowing formulation of theoretical relationships with rigor, generality, and simplicity.
2. It is argued that mathematics allows economists to form meaningful, testable propositions about wide-ranging and complex subjects which could less easily be expressed informally. Further, the language of mathematics allows economists to make specific, positive claims about controversial or contentious subjects that would be impossible without mathematics. Much of economic theory is currently presented in terms of mathematical economic models, a set of stylized and simplified mathematical relationships asserted to clarify assumptions and implications.
3. Economics became more mathematical as a discipline throughout the first half of the 20th century, but introduction of new and generalized techniques in the period around the Second World War, as in game theory, would greatly broaden the use of mathematical formulations in economics.

Transport economics
1. Transport economics is a branch of economics that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip (the final good, in the consumer's eyes) may require the bundling of services provided by several firms, agencies and modes.
2. Although transport systems follow the same supply and demand theory as other industries, the complications of network effects and choices between dissimilar goods (e.g. car and bus travel) make estimating the demand for transportation facilities difficult.
3. In transport, demand can be measured in number of journeys made or in total distance traveled across all journeys (e.g. passenger-kilometers for public transport or vehicle-kilometers of travel (VKT) for private transport). Supply is considered to be a measure of capacity. The price of the good (travel) is measured using the generalized cost of travel, which includes both money and time expenditure.

Checks and Balances
1. The U.S. Constitution establishes three branches for the federal government: executive, legislative, and judicial. The three branches work together to help the country. Each branch has its own responsibilities and powers. No branch has more power than the other branches. They have balanced powers. Each branch has separate duties to check the powers of the other branches.
2. When a new state – the USA – was born, the Founders of the state thought that if there was no balance of power among different branches of government it would lead to tyranny. The problem was how to create a system of government with balanced powers. That’s why James Madison (1751 – 1836) favored the constitution that limited government by means of a) separation of powers; b) a system of checks and balances, where checks – limitation of the duties of each branch, and balances – separate powers to each branch.
3. Congress has the power to make laws, but the President may veto any act of Congress. Congress, in its turn, can pass a law over a veto by a two-thirds vote in each house. Congress can also refuse to provide funds requested by the President. The President can appoint important officials of his administration, but they must be approved by the Senate. The President also has the power to name all federal judges: they, too, must be approved by the Senate.
4.  The system of checks and balances makes compromise and consensus necessary. This system protects against extremes. It means, for example, that new presidents cannot radically change governmental policies just as they wish.

Criminal Procedure
1. Criminal procedure, also called the criminal process, is the mechanism through which crimes are investigated, the guilt of criminals adjudicated, and punishment imposed. Criminal procedure makes the criminal law work. Criminal law defines what conduct is criminal and prescribes the punishment for criminal conduct. Criminal procedure aims to make sure that criminal sanctions are applied only to those who are guilty, and only through procedures that are recognized as fair. One goal of the criminal process is to punish the guilty, but other goals are to protect the innocent and to ensure that even the guilty are protected from abuse by the government.
2. The stages in criminal procedure are investigating, prosecuting, trying, deciding guilt, sentencing and carrying out the sentence. Different bodies can be given one of these jobs. For example, the police can be in charge of investigating the crime; a prosecution service of prosecuting; the judges of presiding over the trial; a jury of deciding whether to convict; an appeal court of settling whether the trial was fair; a prison service of carrying out the sentence if the suspect is convicted and sentenced to prison.
3. No one authority (police, prosecution, judge, jury, prison service) should have too much power. State powers should be sliced up, and the slices should be able to keep a check on one another. The police will not be able to prosecute unless they can persuade the prosecution service that there is a strong case. The judge will if necessary rule at the trial that the prosecution has not produced enough evidence. If the jury think the judge has shown bias during the trial they will probably acquit the suspect even though they might otherwise convicted him. If the suspect is convicted but thinks the procedure has been unfair he can persuade the government to advise the head of state to pardon him.

A company commercial lawyer
1. Sophie Brittle is talking about her work at Melton Deans.
I’m a partner in a medium-sized regional law firm, working within the Company Commercial Department. I head up a team of eight, comprising six lawyers and two paralegals – legal researchers – undertaking projects work for Public Sector clients. Our main client is a Government Department. We’re instructed by them to advise and act on Private Finance Initiative Projects, also known аs the PFI. This involves negotiating with a number of other parties comprising the funders, the building contractors and facilities management and ensuring that the client’s aims and objectives аге met and their best interests protected.
2. A significant proportion of my time is spent in all parties meetings. As these transactions are complex, and the meetings are attended by all sides and their legal advisers. I have to make sure comprehensive notes are taken by an assistant solicitor. Following a meeting, documents reflecting the terms agreed are prepared and circulated for approval.
3. Within the practice, I’m a member of the Executive Committee and have responsibility for aspects of financial management within the department. I also deal with recruitment, training, and development within the department. During a working day as a fee earner, I have to combine my chargeable work for clients with administrative duties.
