why do we study the structure of an economy

WHY STUDY ECONOMICS AS AN UNDERGRADUATE? Economics is the study of how societies, governments, businesses, households, and individuals allocate their scarce resources. Our discipline has two important features. First, we develop conceptual models of behavior to predict responses to changes in policy and market conditions. Second, we use rigorous statistical analysis to investigate these changes. Economists are well known for advising the president and congress on economic issues, formulating policies at the Federal Reserve Bank, and analyzing economic conditions for investment banks, brokerage houses, real estate companies, and other private sector businesses. They also contribute to the development of many other public policies including health care, welfare, and school reform and

 why was the constitutional convention closed to the public

why was the constitutional convention closed to the public

As evidenced by the Watergate scandal and the countless other БgatesБ that have followed, the American people do not like their politicians conducting government in secret. Which is ironic because the American government was created in secret. This week (May 29) in 1787 at the Constitutional Convention in Philadelphia, which would produce the Constitution on which our government is based, the convention delegates agreed to protect themselves from the Бlicentious publications of their proceedingsБ by voting to keep those proceedings a complete secret from all outsiders, including (especially) the press. And except for one unfortunate incident in which a delegate mislaid his convention notes, that secrecy rule was unfailingly observed. бThose mislaid notes, by the way, were found by another

There was this recent Why not just use text files? What can RDBMS do that a simple text file cannot? Or, why not use several different text files to represent different tables? Heh. LetБs challenge that through a witty comparison (also given as an Short story (not to be taken too seriously): Some people just put their keys, wallets, make-up, letters, pencils, more make-up, change, and all the other stuff in a huge purse, spending hours to find stuff when we need to catch the train. Stuff, which they might have actually put in that other purse. LetБs call this purse the text file I like to structure my stuff. My index says: Wallet in the back pocket, key in the front right pocket, mobile phone in the front left pocket, glasses on my nose. LetБs call this structure the RDBMS. Long story:

 why we need to protect endangered species

why we need to protect endangered species

The Endangered Species Act (ESA), passed in 1973, was enacted to halt the rapid loss of plant and animal life. Frequently referred to as the crown jewel of our nation s environmental laws, the ESA has been responsible for saving many species formerly on the brink of extinction, including the bald eagle, gray wolf and California sea otter. The ESA is the only piece of environmental legislation to date that does not demand a cost-benefit analysis before going into action, making it uniquely effective. Once a species is declared threatened or endangered, the ESA ensures that it will be protected and all efforts will be made to assist in its recovery. The Endangered Species Act is not just our strongest environmental law it also articulates a noble vision. In it, for the first time in world

 why do we need to pray for each other

why do we need to pray for each other

Learning to pray for others is one of the first things we learn as Christians: we see it commended on every other page of the New Testament; we see it modelled in every other meeting of Christians we participate in; and Christian parents model it to their children from birth. Have you ever stopped to think about why we pray for others, however? Or why we ask prayer from others? I was made to really consider the question when I first read through 2 Corinthians 1. And what the Apostle Paul says there continues to provoke me to thought and wonder every time I read it. More of that passage in a moment; but I guess, at the most basic level, we pray for our friends because we love them. We desire their good, we desire their growth: we desire their conversion and conformity to Christ. And what

 why do praying mantis eat the male after mating

why do praying mantis eat the male after mating

Surprisingly enough, this is actually a myth! Sort of. It has been around for a long time and its said that the female will detach and consume the head of her mate during, or sometimes immediately after, copulation. Occasionally she will even eat the whole body. The reason given for this is, it provides the female with a vital source of protein to help her produce lots of healthy eggs. This rumour was challengedPwith one notable study published in 1984. A group of entomologists closely watched 30 pairs of praying mantises and not one of the males was unfortunate enough to suffer from post-coital decapitation. This has also been observed and noted by numerous other scientists, further confirming the discovery. Although the males arent quite out of the danger zone, sometimes the females do

 why do people think obama is a socialist

why do people think obama is a socialist

Look at his actions! Look at some of the legislation our Dear Leader has tried to (and / or has) passed over the course of his presidency. The Affordable Care Act (AKA Obamacare) is a system of national healthcare in which those who could not afford healthcare otherwise are being given benefits they cannot afford, and those who do not need these benefits (or who need other coverage options) are forced to take them anyway, and pay extra for all others. This is the distribution of wealth - socialism. It is unfair to the producing members of society - the job makers and those who work hard in their professions. It takes money away from them to pay for those who do not work hard and cannot afford healthcare for themselves. What, then, is the incentive for anybody to produce if it will just be

 why do plants need to produce amino acids

why do plants need to produce amino acids

Plants need to build the complex molecules they need from minerals (elements and simple compounds), which they get from the soil. Animals on the other hand get their complex molecules ready made from their food в they need very few minerals to supplement their diet. If a plant shows poor growth it may be due to a lack of one or more minerals in the soil. It's possible to do chemical tests to find out which minerals are deficient, but it's often more convenient to add a general fertiliser. This is sometimes called NPK fertiliser because it contains the elements nitrogen (N), phosphorus (P) and potassium (K). ...
